GTAP-AGR: A Framework for Assessing the Implications of Multilateral Changes in Agricultural Policies
Authors: Keeney Roman , Hertel Thomas
Published: June 2023

Global models of agricultural trade have a long and distinguished history. The introduction of the GTAP data base and modeling project represented a significant advance forward as it put modelers and trade policy analysts on common ground. After an initial generation of GTAP based modeling of agricultural trade policy using the standard modeling framework, individual researchers have begun introducing agricultural specificity into the standard modeling framework in order to better capture the particular features of the agricultural economy pertinent to their research questions. This technical paper follows in that same tradition by reviewing important linkages between international trade and the farm and food economy and introducing them into the standard GTAP modeling framework, offering a special purpose version of the model nicknamed GTAP-AGR. We introduce this agricultural specificity by introducing new behavioral relationships into the standard GTAP framework. We focus particular attention on the factor markets, which play a critical role in determining the incidence of producer subsidies. This includes modifying both the factor supply and derived demand equations. We also modify the specification of consumer demand, assuming separability of food from non-food commodities. Finally, we introduce the important substitution possibilities amongst feedstuffs used in the livestock sector. Where possible we support these new behavioral relationships with literature-based estimates of both the mean and standard deviation of behavioral parameters. The express purpose of this is to support systematic sensitivity analysis with respect to policy reform scenarios performed with GTAP-AGR. In addition to documenting these extensions to the standard modeling framework, the paper has an additional goal, and that is to gauge the performance of the GTAP-AGR model and how it differs from the standard GTAP framework. We do this primarily by comparing the farm level supply and demand response in terms of policy incidence for the two frameworks. In addition, we evaluate the ability of both models to reproduce observed price volatility in an effort to validate the performance of these models. Finally, we evaluate the results of the two models in a side-by-side comparison of results from full liberalization of agricultural and non-agricultural support.
Towards An Integrated Land Use Database for Assessing the Potential for Greenhouse Gas Mitigation
Authors: Lee Huey-Lin , Hertel Thomas , Sohngen Brent , Ramankutty Navin
Published: June 2023

This paper describes the GTAP Land Use Data Base designed to support integrated assessments of the potential for greenhouse gas mitigation. It disaggregates land use by agro-ecological zone (AEZ). To do so, it draws upon global land cover data bases, as well as state-of-the-art definition of AEZs from the FAO and IIASA. Agro-ecological zoning segments a parcel of land into smaller units according to agro-ecological characteristics, including: precipitation, temperature, soil type, terrain conditions, etc. Each zone has a similar combination of constraints and potential for land use. In the GTAP-AEZ Data Base, there are 18 AEZs, covering six different lengths of growing period spread over three different climatic zones. Land using activities include crop production, livestock raising, and forestry. In so doing, this extension of the standard GTAP Data Base permits a much more refined characterization of the potential for shifting land use amongst these different activities. When combined with information on greenhouse gas emissions, this data base permits economists interested in integrated assessment of climate change to better assess the role of land use change in greenhouse gases mitigation strategies.
Reconciling Trade Statistics from China, Hong Kong and Their Major Trading Partners--A Mathematical Programming Approach
Authors: Wang Zhi , Gehlhar Mark , Yao Shunli
Published: June 2023

This paper develops a mathematical programming model to simultaneously estimate re-export markups and reconcile bilateral trade statistics between China, Hong Kong, and their trading partners. The model is applied to sector level trade flows to resolve discrepant reporting in an efficient manner. Adjustments in trade flows are based upon statistical reporters’ reliability information. The program is implemented in GAMS and retains many desirable theoretical and empirical properties. Estimates are used for generating trade flows and markups for Hong Kong’s re-exports used in the forthcoming version 7 GTAP database. The model’s flexibility has potential for expanded use in other regions where re-exports and associated markup cause discrepant trade flows.
New Estimates of Soil and Biomass Carbon Stocks for Global Economic Models
Authors: Gibbs Holly , Yui Sahoko , Plevin Richard
Published: June 2023

We synthesized a range of geographically-explicit forest, grassland and cropland biomass and soil carbon input data sources and used geographic information systems (GIS) software to calculate new estimates of soil and biomass carbon stocks for use with global economic models, particularly for the Global Trade and Analysis Project (GTAP). Our results quantify the average amount of carbon stored in soil and biomass in each of the 246 countries, stratified by agro-ecological zones (available in the accompanying spreadsheet). We also provide the data aggregated to the 134 regions defined for the GTAP 8.1 database both in spreadsheet form and in GTAP’s native binary file format. Finally, we provide an add-on to FlexAgg2 program to further aggregate the 134 regions as desired. Our analysis makes substantial refinements to the estimates of carbon stocks used for modeling carbon emissions from indirect land use change. The spatial detail of our analysis is a major advantage over previous databases because it provides estimates tailored to the regions of interest and better accounts for the variation of carbon stocks across the landscape, and between wetland and non-wetland regions.

Future-mindedness on homeless and beggars undergoing rehabilitation
Authors: Nurchayati Nurchayati , Rizqiyah Aulia Rachmah
Published: June 2023

Homelessness and beggary are social problems, particularly for urban community. The Indonesian government has long used rehab centers to train vagrants and beggars to be fully functioning members of society. Future-mindedness is one of the life-attitudes that the homeless and beggars are to learn to adopt. Using the case study approach, this qualitative psychological research explores future-mindedness among vagrants and beggars undergoing rehab programs. Data were collected through semi-structured interviews with four participants and two of their significant others. The thematic analysis conducted on the interview data produced three key findings: a) the circumstances that had helped bring about beggary and vagrancy; b) the ways the beggars and vagrants learned to plan their lives; and c) the factors that enabled them to think about the future. This study concludes that employment, place of residence, and family life formed the center of these people’s future plans. Rehab programs—if they are to succeed—must take into account both the personal context and the social environment in which beggars and vagrants have lived their lives and are learning to re-think their futures.

Effect of proton irradiation on the properties of high-voltage integrated 4H-SiC Schottky diodes at operating temperatures
Authors: Lebedev  A. A.  , Kozlovski V. V.  , Levinshtein M. E.  , Malevsky D. A.  , Oganesyan G. A.
Published: June 2023

The effect of proton irradiation (proton energy 15 MeV) on the parameters of high-voltage 4H-SiC integrated Schottky diodes (JBS) was studied for the first time in the operating temperature range Ti (23 and 175oC). The blocking voltage of the diodes under study, Ub, was 600 and 1700 V. For devices with U_b = 600 V, the fluence range was 5·1013-1·1014 cm-2; for devices with U_b=1700 V, the fluence range was 3·1013-6·1013 cm-2. An increase in the irradiation temperature leads to a noticeable decrease in the effect of irradiation on the current-voltage characteristics of the diodes. The effect of annealing on the current-voltage characteristics of irradiated devices is studied. Keywords: Silicon carbide, Schottky diodes, proton irradiation, current-voltage characteristics, annealing.

Published: June 2023

Background

Zambia is facing a severe shortage of health care workers, particularly in rural areas. Innovative educational programs and infrastructure have been established to bridge this gap; however, they encounter substantial challenges because of constraints in physical and human resources. In response to these shortcomings, strategies such as web-based and blended learning approaches have been implemented, using virtual patients (VPs) as a means to promote interactive learning at the Levy Mwanawasa Medical University (LMMU) in Zambia.

Objective

This study aimed to evaluate the students’ knowledge acquisition and acceptance of 2 VP medical topics as a learning tool on a Zambian higher education e-learning platform.

Methods

Using a mixed methods design, we assessed knowledge acquisition using pre- and posttests. In a randomized controlled trial setting, students were assigned (1:1) to 2 medical topics (topic 1: appendicitis and topic 2: severe acute malnutrition) and then to 4 different learning tools within their respective exposure groups: VPs, textbook content, preselected e-learning materials, and self-guided internet materials. Acceptance was evaluated using a 15-item questionnaire with a 5-point Likert scale.

Results

A total of 63 third- and fourth-year Bachelor of Science clinical science students participated in the study. In the severe acute malnutrition–focused group, participants demonstrated a significant increase in knowledge within the textbook group (P=.01) and the VP group (P=.01). No substantial knowledge gain was observed in the e-learning group or the self-guided internet group. For the appendicitis-focused group, no statistically significant difference in knowledge acquisition was detected among the 4 intervention groups (P=.62). The acceptance of learning materials exhibited no substantial difference between the VP medical topics and other learning materials.

Conclusions

In the context of LMMU, our study found that VPs were well accepted and noninferior to traditional teaching methods. VPs have the potential to serve as an engaging learning resource and can be integrated into blended learning approaches at LMMU. However, further research is required to investigate the long-term knowledge gain and the acceptance and effectiveness of VPs in medical education.

Economic Evaluation of Digital Therapeutic Care Apps for Unsupervised Treatment of Low Back Pain: Monte Carlo Simulation
Authors: Lewkowicz Daniel , Bottinger Erwin , Siegel Martin
Published: June 2023

Background

Digital therapeutic care (DTC) programs are unsupervised app-based treatments that provide video exercises and educational material to patients with nonspecific low back pain during episodes of pain and functional disability. German statutory health insurance can reimburse DTC programs since 2019, but evidence on efficacy and reasonable pricing remains scarce. This paper presents a probabilistic sensitivity analysis (PSA) to evaluate the efficacy and cost-utility of a DTC app against treatment as usual (TAU) in Germany.

Objective

The aim of this study was to perform a PSA in the form of a Monte Carlo simulation based on the deterministic base case analysis to account for model assumptions and parameter uncertainty. We also intend to explore to what extent the results in this probabilistic analysis differ from the results in the base case analysis and to what extent a shortage of outcome data concerning quality-of-life (QoL) metrics impacts the overall results.

Methods

The PSA builds upon a state-transition Markov chain with a 4-week cycle length over a model time horizon of 3 years from a recently published deterministic cost-utility analysis. A Monte Carlo simulation with 10,000 iterations and a cohort size of 10,000 was employed to evaluate the cost-utility from a societal perspective. Quality-adjusted life years (QALYs) were derived from Veterans RAND 6-Dimension (VR-6D) and Short-Form 6-Dimension (SF-6D) single utility scores. Finally, we also simulated reducing the price for a 3-month app prescription to analyze at which price threshold DTC would result in being the dominant strategy over TAU in Germany.

Results

The Monte Carlo simulation yielded on average a €135.97 (a currency exchange rate of EUR €1=US $1.069 is applicable) incremental cost and 0.004 incremental QALYs per person and year for the unsupervised DTC app strategy compared to in-person physiotherapy in Germany. The corresponding incremental cost-utility ratio (ICUR) amounts to an additional €34,315.19 per additional QALY. DTC yielded more QALYs in 54.96% of the iterations. DTC dominates TAU in 24.04% of the iterations for QALYs. Reducing the app price in the simulation from currently €239.96 to €164.61 for a 3-month prescription could yield a negative ICUR and thus make DTC the dominant strategy, even though the estimated probability of DTC being more effective than TAU is only 54.96%.

Conclusions

Decision-makers should be cautious when considering the reimbursement of DTC apps since no significant treatment effect was found, and the probability of cost-effectiveness remains below 60% even for an infinite willingness-to-pay threshold. More app-based studies involving the utilization of QoL outcome parameters are urgently needed to account for the low and limited precision of the available QoL input parameters, which are crucial to making profound recommendations concerning the cost-utility of novel apps.
A Web-Based Instrument for Infantile Atopic Dermatitis Identification (Electronic Version of the Modified Child Eczema Questionnaire): Development and Implementation
Authors: Fang Heping , Chen Lin , Li Juan , Ren Luo , Yin Yu , Chen Danleng , Yin Huaying , Liu Enmei , Hu Yan , Luo Xiaoyan
Published: June 2023

Background

Atopic dermatitis (AD) is a chronic inflammatory cutaneous disease that affects 30.48% of young children; thus, there is a need for epidemiological studies in community settings. Web-based questionnaires (WBQs) are more convenient, time-saving, and efficient than traditional surveys, but the reliability of identifying AD through WBQs and whether AD can be identified without the attendance of doctors, especially in community or similar settings, remains unknown.

Objective

This study aimed to develop and validate a web-based instrument for infantile AD identification (electronic version of the modified Child Eczema Questionnaire [eCEQ]) and to clarify the possibility of conducting WBQs to identify infantile AD without the attendance of doctors in a community-representative population.

Methods

This study was divided into 2 phases. Phase 1 investigated 205 children younger than 2 years to develop and validate the eCEQ by comparison with the diagnoses of dermatologists. Phase 2 recruited 1375 children younger than 2 years to implement the eCEQ and verify the obtained prevalence by comparison with the previously published prevalence.

Results

In phase 1, a total of 195 questionnaires were analyzed from children with a median age of 8.8 (IQR 4.5-15.0) months. The identification values of the eCEQ according to the appropriate rules were acceptable (logic rule: sensitivity 89.2%, specificity 91.5%, positive predictive value 97.1%, and negative predictive value 72.9%; statistic rule: sensitivity 90.5%, specificity 89.4%, positive predictive value 96.4%, and negative predictive value 75%). In phase 2, a total of 837 questionnaires were analyzed from children with a median age of 8.4 (IQR 5.2-14.6) months. The prevalence of infantile AD obtained by the eCEQ (logic rule) was 31.9% (267/837), which was close to the published prevalence (30.48%). Based on the results of phase 2, only 20.2% (54/267) of the participants identified by the eCEQ had previously received a diagnosis from doctors. Additionally, among the participants who were not diagnosed by doctors but were identified by the eCEQ, only 6.1% (13/213) were actually aware of the possible presence of AD.

Conclusions

Infantile AD can be identified without the attendance of doctors by using the eCEQ, which can be easily applied to community-based epidemiological studies and provide acceptable identification reliability. In addition, the eCEQ can also be applied to the field of public health to improve the health awareness of the general population.
Evaluating the Supporting Evidence of Medical Cannabis Claims Made on Clinic Websites: Cross-Sectional Study
Authors: O'Neill Braden , Ferguson Jacob , Dalueg Lauren , Yusuf Abban , Kirubarajan Abirami , Lloyd Taryn , Mollanji Eisi , Persaud Navindra
Published: June 2023

Background

Since the legalization of medical cannabis in Canada in 2013, prescription of cannabis for medical purposes has become commonplace and a multibillion dollar industry has formed. Much of the media coverage surrounding medical cannabis has been positive in nature, leading to Canadians potentially underestimating the adverse effects of medical cannabis use. In recent years, there has been a large increase in clinic websites advertising the use of medical cannabis for health indications. However, little is known about the quality of the evidence used by these clinic websites to describe the effectiveness of cannabis used for medical purposes.

Objective

We aimed to identify the indications for medical cannabis reported by cannabis clinics in Ontario, Canada, and the evidence these clinics cited to support cannabis prescription.

Methods

We conducted a cross-sectional web search to identify all cannabis clinic websites within Ontario, Canada, that had physician involvement and identified their primary purpose as cannabis prescription. Two reviewers independently searched these websites to identify all medical indications for which cannabis was promoted and reviewed and critically appraised all studies cited using the Oxford Centre for Evidence-Based Medicine Levels of Evidence rubric.

Results

A total of 29 clinics were identified, promoting cannabis for 20 different medical indications including migraines, insomnia, and fibromyalgia. There were 235 unique studies cited on these websites to support the effectiveness of cannabis for these indications. A high proportion (36/235, 15.3%) of the studies were identified to be at the lowest level of evidence (level 5). Only 4 clinic websites included any mention of harms associated with cannabis.

Conclusions

Cannabis clinic websites generally promote cannabis use as medically effective but cite low-quality evidence to support these claims and rarely discuss harms. The recommendation of cannabis as a general therapeutic for many indications unsupported by high-quality evidence is potentially misleading for medical practitioners and patients. This disparity should be carefully evaluated in context of the specific medical indication and an individualized patient risk assessment. Our work illustrates the need to increase the quality of research performed on the medical effects of cannabis.
Effectiveness of Telegenetic Counseling for Patients and Families With Suspected Hereditary Cancer: Systematic Review (Preprint)
Authors: Shibuya Yuriko , Harada Tomoyo , Aoki Mikiko , Ota Erika , Kamei Tomoko
Published: June 2023

BACKGROUND

Telegenetic counseling has attracted attention as a preventive measure against the recent COVID-19 pandemic. This systematic review compared telegenetic counseling using videoconferencing versus face-to-face counseling for hereditary cancer.

OBJECTIVE

This study aimed to evaluate the effectiveness of telegenetic counseling using videoconferencing versus face-to-face counseling for people with suspected hereditary cancer.

METHODS

A comprehensive literature search was carried out in December 2021 using the databases of the Japan Medical Abstracts Society, PubMed, CINAHL, PsycInfo, EMBASE, and the Cochrane Library. The eligibility criteria were studies in which randomized controlled trials (RCTs) or cluster RCTs were conducted among patients with suspected hereditary cancer and their families, comparing telegenetic counseling using videoconferencing with face-to-face genetic counseling. The Cochrane risk-of-bias tool was used to assess the risk of bias of each RCT study. This study was reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines.

RESULTS

Two studies comprising a total of 191 participants were included and used for meta-analysis. Participants were individuals who lived in rural areas or in areas without genetic counselors and were suspected to have breast, colon, ovarian, multiple, or genetic cancer. All outcomes were assessed in only 1 study and their effects could not be discussed explicitly. In one study, there were no significant differences in satisfaction, psychological distress, or a number of genetic tests between face-to-face genetic counseling and telegenetic counseling. The cost per patient for genetic counseling was $106.19 for the telegenetics group and $244.33 for the in-person group. The risk of bias was high in both studies, with a high risk of performance bias, detection bias, and attrition bias.

CONCLUSIONS

The results of the two RCTs were described qualitatively. However, the evidence is limited because of the small number of RCT studies on telegenetic counseling and the high risk of bias. Further accumulation of studies is needed in the future.

Published: June 2023

BACKGROUND

Hypoglycemia remains a challenge for roughly 25% of people with type 1 diabetes (T1D) despite using advanced technologies such as continuous glucose monitors (CGMs) or automated insulin delivery systems. Factors impacting hypoglycemia self-management behaviors (including reduced ability to detect hypoglycemia symptoms and unhelpful hypoglycemia beliefs) can lead to hypoglycemia development in people with T1D who use advanced diabetes technology.

OBJECTIVE

This study aims to develop a scalable, personalized mobile health (mHealth) behavioral intervention program to improve hypoglycemia self-management and ultimately reduce hypoglycemia in people with T1D who use advanced diabetes technology.

METHODS

We (a multidisciplinary team, including clinical and health psychologists, diabetes care and education specialists, endocrinologists, mHealth interventionists and computer engineers, qualitative researchers, and patient partners) jointly developed an mHealth text messaging hypoglycemia behavioral intervention program based on user-centered design principles. The following five iterative steps were taken: (1) conceptualization of hypoglycemia self-management processes and relevant interventions; (2) identification of text message themes and message content development; (3) message revision; (4) patient partner assessments for message readability, language acceptability, and trustworthiness; and (5) message finalization and integration with a CGM data–connected mHealth SMS text message delivery platform. An mHealth web-based SMS text message delivery platform that communicates with a CGM glucose information-sharing platform was also developed.

RESULTS

The mHealth SMS text messaging hypoglycemia behavioral intervention program HypoPals, directed by patients’ own CGM data, delivers personalized intervention messages to (1) improve hypoglycemia symptom detection and (2) elicit self-reflection, provide fact-based education, and suggest practical health behaviors to address unhelpful hypoglycemia beliefs and promote hypoglycemia self-management. The program is designed to message patients up to 4 times per day over a 10-week period.

CONCLUSIONS

A rigorous conceptual framework, a multidisciplinary team (including patient partners), and behavior change techniques were incorporated to create a scalable, personalized mHealth SMS text messaging behavioral intervention. This program was systematically developed to improve hypoglycemia self-management in advanced diabetes technology users with T1D. A clinical trial is needed to evaluate the program’s efficacy for future clinical implementation.

During herpetofauna monitoring in Misión Nueva Pompeya locality, Chaco province, Argentina, an adult individual of the toad Rhinella major was captured. We examined the specimen and found a tick attached to the ventral surface of its body. The tick was identified as a nymph of Amblyomma argentinae, an ectoparasite considered specific to reptiles. This finding is the first record of this parasite-host association, and increases the host range of A. argentinae up to 16 species.
HIGH ECTOPARASITIC LEECH LOAD IN THE MOUNTAIN TREE FROG Hyla eximia (Hylidae) CAUSED BY ANTHROPIZATION
Authors: Gómez Benitez Aldo , Reyes Velázquez Erika Adriana , Hernández Gallegos Oswaldo
Published: June 2023

IIn June 2021, parasitism by leeches of the genus Helobdella was observed for the first time in Hyla eximia during an irrigation canal monitoring. This event occurred shortly after the canals were opened to supply an agroecosystem in The Cerrillo, Piedras Blancas, Toluca de Lerdo, State of Mexico, Mexico. The frog was trapped in one of the canal beds, which had an abundant presence of duckweed (Lemna minor). We analyzed the load and distribution of the parasitic leeches on the frog’s body. An obvious difficulty in individual locomotion was observed. The observed parasite load of 65 leeches is one of the highest ever recorded in anurans. Our findings highlight the importance of parasitic load in the host fitness and suggest a potential relationship between anthropization and the magnitude of these interactions.
Development of a 3D-printed bioabsorbable composite scaffold with mechanical properties suitable for treating large, load-bearingarticular cartilage defects
Authors: Joyce M , Hodgkinson T , Lemoine M , González-Vázquez A , Kelly DJ , O’Brien FJ
Published: June 2023

Extracellular matrix (ECM) biomaterials have shown promise for treating small artucular-joint defetcs. However, ECM-based biomaterials generally lack appropriate mechanical properties to support physiological loads and are prone to delamination in larger cartilage defects. To overcome these common mechanical limitations, a collagen hyaluronic-acid (CHyA) matrix, with proven regenerative potential, was reinforced with a bioabsorbable 3D-printed framework to support physiological loads. Polycaprolactone (PCL) was 3D-printed in two configurations, rectilinear and gyroid designs, that were extensively mechanically characterised. Both scaffold designs increased the compressive modulus of the CHyA matrices by three orders of magnitude, mimicking the physiological range (0.5-2.0 MPa) of healthy cartilage. The gyroid scaffold proved to be more flexible compared to the rectilinear scaffold, thus better contouring to the curvature of a femoral condyle. Additionally, PCL reinforcement of the CHyA matrix increased the tensile modulus and allowed for suture fixation of the scaffold to the subchondral bone, thus addressing the major challenge of biomaterial fixation to articular joint surfaces in shallow defects. In vitro evaluation confirmed successful infiltration of human mesenchymal stromal cells (MSCs) within the PCL-CHyA scaffolds, which resulted in increased production of sulphated glycosaminoglycans (sGAG/DNA; p = 0.0308) compared to non-reinforced CHyA matrices. Histological staining using alcian blue confirmed these results, while also indicating greater spatial distribution of sGAG throughout the PCL-CHyA scaffold. These findings have a great clinical importance as they provide evidence that reinforced PCL-CHyA scaffolds, with their increased chondroinductive potential and compatibility with joint fixation techniques, could be used to repair large-area chondral defects that currently lack effective treatment options.
College Students' Social Media Addiction and Sleep Problems: Chain Mediating Effects of Fear of Missing Out and Nocturnal Social Media Use

This study investigated the effect of social media addiction on sleep problems in college students, and the chain mediating effects in this relationship of fear of missing out and nocturnal social media use. We conducted a survey of 907 college students in China using the Social Media
Addiction Scale, the Fear of Missing Out Scale, the Nocturnal Social Media Use Scale, and the Pittsburgh Sleep Index Scale. Results showed that social media addiction significantly and positively predicted poor sleep quality, and that fear of missing out and nocturnal social media use had
a chain mediating effect in this relationship. Reducing social media addiction and nocturnal social media use, and developing education-guided measures aimed at reducing fear of missing out will be beneficial to improving the sleep quality of college students.
The Effect of Daily Stress on Depression in Chinese Adolescents: A Moderated Mediation Model
Authors: Wang Yao , Yu Zengyan
Published: June 2023

We explored the effects and mechanisms of daily perceived stress on depression among Chinese adolescents. Participants were 1,153 junior high school students who completed The Adolescent Self-Rating Life Events Checklist, the Positive and Negative Affect Scale-Children, the Socioeconomic
Status Scale, the Emotional Control Scale, and the Center for Epidemiological Studies Depression Scale. Results showed that daily stress was positively related to depression, and emotional balance partially mediated this relationship. The relationship between emotional balance and depression
was moderated by emotional control and socioeconomic status, such that the impact of emotional balance on depression was stronger for adolescents with low emotional control and high socioeconomic status. We have revealed the behavioral mechanism underlying the association between daily stress
and depression, enriching the literature on youth positive development. For those working with adolescents, to prevent depression the focus should be on maintaining daily emotional balance by improving emotional control, while paying attention to the emotional problems of adolescents with
low socioeconomic status.

Environmental protection is not only a social dilemma, it is also a temporal dilemma influencing the survival of all human beings. Drawing from the temporal focus literature, we proposed that individuals with a stronger (vs. weaker) future temporal focus would engage in more proenvironmental
behaviors via greater environmental commitment. Integrating trait activation theory, we further proposed that environmental resource scarcity would strengthen the process we had already proposed. We tested our proposals with 591 university students in Eastern China, who completed an anonymous
survey. The data were collected in three waves with a 2-week interval between each wave. A structural equation model was applied to test the hypotheses. Future temporal focus significantly influenced participants' proenvironmental behavior via their environmental commitment, and the positive
influence was stronger when the environmental resource was scarce. This study enriches the environmental protection literature by providing a temporal framework. The theoretical and practical implications of proenvironmental behavior are discussed.

Objectives The purpose of this study is to provide a foundation for career education and guidance for science gifted students by vividly examining the college life experience and career development process of science gifted college students.
Methods This study was conducted using a narrative inquiry method to reveal in-depth detail of the career development experience of the participants. Three college students at a science and technology university in a metropolitan city participated in the study. Transcription data of in-depth interviews centered on semi-structured questionnaires, researcher’s field notes, e-mail and text messages exchanged with the participants, and their writings were collected and analyzed according to the method suggested by Clandinin and Connelly(2000).
Results Results indicated that the research participants’ stories were organized in the order of before entering the college, college life, and future career plans. The meaning of their college life experience in their career development process was [overcoming setbacks and moving on my way], [people who help me grow], and [having outlets for stress]. From the researchers’ perspective, it was found that they were actively participating in college life while struggling to discover and solidify their own personal identity to form social and professional identities.
Conclusions Based on the results, the personal justification of the researchers, practical justification for the field of career education and guidance for science gifted students, and social justification to create a better social environment were revealed. The implications and limitations of the study were discussed.

Objectives The purposes of this study is to examine the effects of the factors in E-learning environment due to COVID19 on 2020 National Assessment of Education Achievement(NAEA) for English subject among high school students.
Methods About 3 % of sampling classes were participated in NAEA. The achievement test results and the survey results of 10,526 2nd grade of high school students were used in the analysis except the missing values. The demographic characteristics(gender and regional scale) were served as the control variable and hierarchical regression analysis was used.
Results The research results identifies the factors in E-learning environment affecting scholastic achievement of the English subject after controlling gender and regional scale. Model 1 explains approximately 3.6% and Model 2 shows about 11.9% of coefficient of determination respectably. Students who acknowledge the usefulness of E-learning have higher English scores. Also, students with higher English scores feel that E-learning environment is similar to that of school life. The variables such as ‘time used on private tutoring’, ‘time used on self-directed learning’, ‘anxiety on grade’, ‘interest in learning’ have positive correlation with academic achievement of the English subject. On the other hand, the variables such as ‘sense of belonging to the school’, ‘communication with the teachers regarding career plan’, ‘hangout time with friends’, ‘the amount of home work’, ‘the amount of study’, ‘communication with teachers regarding academic matters’, ‘life style on regular base’ have negative correlation with the academic achievement of the English subject.
Conclusions The students with high level of English academic achievement tend to perceive that the amount of homework and that of learning are reduced in E-learning environment due to COVID19 compared to in-class learning environment. They feel more anxiety on grade, thus spend more time on tutoring and self-directed study in order to make up the lack of study. It is desirable that the results of current study help aware education gap caused by COVID19 and are able to served as a springboard to provide useful information to establish sound educational policy.

Objectives This study is a descriptive research to understand the effects of undergraduate students' SNS addiction proneness, self-esteem on appearance appreciation.
Methods 131 students were extracted with convenience sampling from two universities in U city and included as subjects. Data were collected from July 10 to August 10, 2022, through an online survey method using Google questionnaires, in consideration of the current status of the COVID-19 pandemic and the characteristics of infectious diseases. SPSS 23.0 was used for data analysis and frequency, percentage, t-test, F-test, Pearson correlation, and hierarchical multiple regression were analyzed.
Results Appearance acceptance in undergraduate students' showed a low negative correlation with SNS addiction proneness (r=-.266, p=.002) and a positive correlation with self-esteem (r=.768, p<.001). In the regression analysis, Average number of days accessing SNS (weeks): Less than 6 times a week (β=.17, p=.001), Comparison of negative appearance on SNS: No (β=.18, p=.010), Self-esteem (β=.64, p<.001) appeared as a variable affecting appearance acceptance, explaining 71.7% of appearance appreciation.
Conclusions In order for Undergraduate students' to properly appearance appreciation, it is necessary to increase self-esteem, prevent excessive use of SNS and negative comparison of appearance in SNS, and prepare a plan and education/counseling program to use SNS correctly.
A Study on the Transitivity of Business and Public Interest Advertising in Chinese

Published: June 2023

Objectives The purpose of this paper is to compare the transitivity of business advertising language and public service advertising language in China from the perspective of Systemic Functional Linguistics. Business advertising is a genre that aims to persuade consumers and is highly embedded with consumer sensibilities, while public service advertising is a genre that best reflects the social concerns and changes of an era or country.
Methods According to SFL, there are six types of Process Types in the transitivity: material process, mental process, relational process, existential process, behavioral process, and verbal process. By analyzing Chinese advertising language according to the differences in process types, we can identify the characteristics of business advertising, the characteristics of public service advertising, the differences between business advertising and public service advertising, and the changes in the transitivity at the level of Chinese-Korean translation. Our findings on these issues are as follows.
Results First, business advertising is characterized by a large number of material and mental processes. In particular, mental processes are more prevalent in advertising for alcohol, beverages, and food products. Due to the nature of the industry, advertising for alcohol, beverages, and food products mainly use the senses of sight and taste to recommend products to the audience. This is likely due to the fact that business advertisements use concise language to arouse consumers' desire to buy and generate profits for companies. Second, unlike the high use of mental processes in business advertising, they are very low in public service advertising, and material processes are most prevalent in public service advertising. The prevalence of material processes in public service advertising is likely due to the fact that they are related to the interests of the people as a whole and emphasize the communication purpose of persuasion and appeal to gain the cooperation of the general public. Third, we also examined the changes in the transitivity during the translation process from Chinese to Korean. By comparing the transitivity of the original and translated advertising, we found three types of changes: addition, reduction, and conversion. Through the presentation of major cases of translation variation, we examined the characteristics of each variation and the reasons for its occurrence.
Conclusions The systematic functional linguistic characteristics of Chinese advertising derived from the above analyses would help readers to understand the characteristics of Chinese advertising language, and may also be helpful for those who study Chinese advertising language, develop Chinese slogans, or teach Chinese slogans.
