Nonalcoholic Fatty Liver Disease as a Risk Factor for Prolonged Corrected QT Interval in Apparently Healthy Korean Women
Authors: Chung Tae-Ha , Shim Jae-Yong , Lee Yong-Jae
Published: March 2020

Background and Aims: Nonalcoholic fatty liver disease (NAFLD) is clinically important because of its association with an increased risk of sudden cardiac death as well as liver-related mortality. Most cases of sudden cardiac death could be mediated by an arrhythmogenic process. Thus, we aimed to determine the association between NAFLD and corrected QT (QTc) interval in apparently healthy Korean women.

Methods: This cross-sectional study included 764 women aged 20 to 74 years old who underwent a health examination program between 2014 and 2015. The QTc interval was calculated using Bazett’s formula (QTc = QT/√RR). Multiple linear and logistic regression analysis were performed to assess independent relationships between NAFLD and QTc interval and prolonged QTc (≥ 450 milliseconds) was calculated after adjusting for confounding variables.

Results: The overall prevalence of NAFLD was 23.5% in general healthy women. The standardized β coefficient (95% confidence interval) of the QTc increment in patients with NAFLD was 6.4 milliseconds (1.2–11.8) through multiple linear regression analysis after adjusting for age, body mass index, smoking status, and regular exercise as well as mean arterial pressure, fasting plasma glucose, triglycerides, high-density lipoprotein cholesterol, aspartate aminotransferase, alanine aminotransferase, calcium, potassium levels and menopause status. Similarly, the odds ratio (95% confidence interval) of NAFLD for prolonged QTc was 2.05 (1.13–3.71) according to multiple logistic regression analysis after adjusting for the same covariables in women aged 20 to 74 years old.

Conclusion: We demonstrated the arrhythmogenic potential of NAFLD, implying that careful monitoring of patient electrocardiograms is necessary to evaluate the possible arrhythmic risk in general healthy women with NAFLD.
Seronegative Coeliac Disease Masquerading as Irritable Bowel Syndrome type Symptoms
Authors: Henry Darrien X. , Sanders David S , Basu Kumar , Schiepatti Annalisa , Campbell Jennifer A.
Published: March 2020

Coeliac disease affects 1% of the population but internationally delays in diagnosis are frequent. A relationship between irritable bowel syndrome type symptoms and coeliac disease is well established and most IBS guidelines recommend that patients presenting with IBS type symptoms should be tested serologically for coeliac disease. Seronegative coeliac disease accounts for 3-5% of all cases of coeliac disease and it is a diagnostic challenge which requires a high level of clinical suspicion and consideration of duodenal biopsies prior to confidently excluding this diagnosis. We report the first case of seronegative coeliac disease masquerading as IBS type symptoms. We suggest that if patients have evidence of haematinic deficiency, subsequent weight loss, features of malabsorption or a family history of coeliac disease, then a duodenal biopsy should be considered irrespective of negative serology.
A Rare Case of Aeroportia Due to Acute Gastric Dilatation - when the Radiologist Goes beyond the Imagess
Authors: Moldovanu Claudia Gabriela , Caraiani Cosmin , Furnea Bogdan , Graur Florin
Published: March 2020

Background & Aims: The development of an esophagorespiratory fistula (ERF) in patients with esophagealcancer (EC) is associated with poor prognosis. We observed a high rate of vocal fold paralysis (VFP) in patientswith ERF. Data on prevalence and complications of VFP in ERF are lacking. The present study investigated theincidence of VFP in patients with malignant ERF and examined possible risk factors and the impact on survival.Methods: We performed a retrospective case-control study of 46 institutional cases of EC patients with ERFin a time period of eleven years. Patients were matched to 92 randomly selected controls (EC patients withoutERF) in a 1:2 fashion for tumor localization and histology. Demographics, clinical characteristics, recurrence,treatment modalities as well as survival were analyzed.Results: Esophageal cancer patients with ERF developed more often VFP than EC patients without ERF (59%vs. 21%; p=0.02; odds ratio (OR) 4.9). Esophageal cancer patients with ERF had a more pronounced weightloss (7.1 vs. 11.5 kg; P = 0.008), as well as higher rates of esophageal (p=<0.001; OR 22.9) and tracheal stenting(p=<0.001; OR 76.8). Proximal tumor growth (p=0.004; OR 7.9), fistula formation to the trachea (p=<0.001;OR 17.2) and recurrent disease (p=0.04, OR 4.7) was associated with VFP development in EC patients withERF. Vocal fold paralysis in ERF did not adversely affect five-year survival.Conclusions: Vocal fold paralysis is a common complication in more than half of the patients with ERF inEC. It is associated with proximal tumor growth, fistula formation to the trachea and disease recurrence, butdoes not influence survival.
Social responsibility of a stock exchange: Corporate governance at Borsa Istanbul
Authors: Inci A. Can
Published: March 2020

Accentuated intraday volatility and uncertainty leads to mispricing, inefficiency, and the potential unfair treatment of some market participants. As an important financial institution, the stock exchange is required to find mechanisms to reduce volatility for good corporate governance and for social responsibility. In this paper, one such mechanism, closing call auction, is explored in the actively traded industrials sector of the emerging Borsa Istanbul. Evidence of the successful implementation of the mechanism is provided. Volatility decreases and efficiency of the prices increases after the implementation of the closing call auction. The exchange executives’ positive engagement in good corporate governance is documented and is suggested to other stock exchanges as a social responsibility instrument.
Determinants of the choice of combined modes for foreign market entry: the case of Korean firms entering into Uzbekistan
Authors: Ra Wonchan
Published: March 2020

The choice of an entry mode is one of the most critical decisions for firms expanding abroad. There are a variety of foreign market entry modes such as exporting, licensing, and foreign direct investment. While many firms use only one single mode, others frequently employ multiple different combined modes for a foreign entry in a package. Mode combination can be an effective way to achieve better performance in foreign operations because of the different modes in a combination package complement each other. The topic of mode combination, however, has not yet been extensively studied theoretically and empirically. In this paper, we examine factors affecting firms’ choice between a single-mode and a combined mode by establishing hypotheses and testing them using questionnaire survey data on Korean manufacturing firms’ recent entry into Uzbekistan.

Published: March 2020

Absztrakt:

Bevezetés: Az őrszemnyirokcsomó-biopszia (SNB) bevezetésével a
hónalji blokkdissectiók (ABD) aránya jelentősen csökkent. Az extracapsularis
terjedés (ECT) jelenléte az őrszemnyirokcsomókban azonban bizonytalan
jelentőségű. Módszer: Retrospektív vizsgálatunkban 635
T1-T2N0M0 klinikai stádiumú emlőrákos beteg adatait elemeztük, akiknél SNB-t
végeztünk 2014 és 2018 között. Az esetek 25%-ában (158 beteg) igazolódott
őrszemnyirokcsomó- (SN) áttét. Az SN-áttétes betegeinket két csoportra osztottuk
aszerint, hogy igazolódott-e az SN-ben ECT, vagy nem. Vizsgálatunk fő célja az
volt, hogy elemezzük a masszív (>3) nyirokcsomóáttét arányát az ECT-negatív
és -pozitív betegeknél, akiknél ABD történt. Eredmények: Az
ECT-negatív csoportba 91/158 beteg (58%), míg az ECT-pozitívba 67/158 beteg
(42%) került. Az ECT-negatív betegek 42%-ánál, az ECT-pozitívok 69%-ánál történt
ABD. Nem találtunk szignifikáns különbséget a következő változókban: életkor,
tumorméret, szövettani típus, grade és lymphovascularis invázió jelenléte,
valamint a hormon- és HER2-receptorok arányai között. Amennyiben az SN-ben nem
igazolódott ECT, de ABD történt, akkor a pN1-érintettség aránya 82%-os, míg a
pN2+pN3 aránya 18%-os volt. Az ECT-pozitív ABD-s csoportban a pN1-érintettség
60%-os volt, míg a pN2+pN3 arány 40%-osnak bizonyult, amely az ECT-negatív
csoport kétszerese; ez a különbség szignifikáns (p = 0,038).
Következtetések: Az ECT a hónalj masszív
nyirokcsomó-érintettség prediktora, ezért ha ECT igazolódik, akkor ez egy olyan
tényező, amelyet az ABD-ről való döntésben figyelembe kell venni.
Bridging the gap between learning and evaluation
Authors: De Backer Fauve
Published: March 2020

The use of non-dominant linguistic repertoires is often not valued in educational practices, let alone in educational assessment. The competences of multilingual learners are traditionally assessed by tests designed for monolinguals that do not represent the true capabilities of multilingual pupils, because their level of language proficiency in the text language does not reflect their wider abilities. Assessment needs to shift from evaluating a pupil in only the language of schooling towards assessment where the full multilingual repertoire can be used to demonstrate knowledge and competences. In this study, assessment preferences of multilingual pupils are explored, both in assessment accommodations for large-scale testing and in classroom-based assessment that is aligned with assessment for learning. Interviews with 35 pupils in fifth-grade of primary education (age 10–11) in Belgium were conducted. Results indicate that accommodations that use pupils’ first languages are not necessarily the most popular ones, that pupils are in favour of portfolios and oral assessments and that they need more feedback. The findings of this study suggest the need for instruction and evaluation to become more integrated, which would be beneficial for all pupils and could be more inclusive of emergent bilinguals rather than treating them as a separate group.
Corpus-based empirical approach to professionalism
Authors: Kong Kenneth , Lam Phoenix , Cheng Winnie
Published: March 2020

Although research on professional competence has has adopted a number of approaches that have highlighted the importance of practice and values in enacting a professional identity, there is currently no established framework for empirical investigations. Based on a discourse analytic framework, this paper demonstrates how ethical codes in a number of consulting professions (law, accountancy and engineering/surveying) can be analyzed empirically by focusing on the collocation patterns found in the genre. The analysis will focus on how professionals are expected to behave in relation to two identity components in their ideal conducts of behavior: identity roles (or identity shifts) and identity virtues (positive attributes associated with a particular role). The engineering profession is found to have a fairly even representation of most of the identity roles identified: provider to client, unspecified/general, professional peer, employer and professional association. The legal profession places greater emphasis on the roles of provider to client and professional peer, whereas accountancy professionals tend to represent their identity roles more generally, although the role of provider to client remains an important category. With regard to identity virtues, i.e., the ideal dispositions or values displayed, all three professions highlight the primacy of professional standards or competence, with integrity and responsibility also emphasized by some.
Novos sonhos de verão sem fim: surfe, mulheres e outros modos de representação
Authors: Dias Cleber
Published: March 2020

Este artigo pretende analisar a maneira que o filme Blue Cruch (2002) - no Brasil A onda dos sonhos - captura, representa e difunde sentidos sobre o surfe. O fundamento da iniciativa é o de que filmes como esse, captam o que a prática de esportes simboliza, atribuindo-lhes assim significados que podem ser interpretados a partir deles mesmos. Nesse caso, três elementos do seu enredo foram tomados como eixo de análise: i) o modo de representação da mulher; ii) a crescente comodificação como forma de se relacionar com esta modalidade; iii) a tendência realística-documental dos filmes de surfe. São dimensões que dramatizam dinâmicas culturais desta modalidade, encerrando uma ambivalência que traduz as disputas, clivagens e tensões próprias a qualquer prática cultural.

Authors: Silva Marcelo Moraes e , Capraro André Mendes
Published: March 2020

O presente artigo objetiva analisar o contexto sócio-político que favoreceu a fundação de uma instituição que visava especificamente formar profissionais na área de Educação Física, a Escola de Educação Física e Desportos do Paraná. Fundada em Curitiba no ano de 1942, a Escola foi fruto de um cenário político amplo, no qual o Estado, permeado por ideais higiênicos/eugênicos, passa a se preocupar mais com a educação formal. Como reflexo, novas condutas físicas e morais foram incorporadas por meio das práticas presentes nos currículos escolares. A Escola de Educação Física e Desportos do Paraná, mesmo com as suas singularidades, fez parte ativamente deste processo.

Published: March 2020

O objetivo deste estudo foi verificar o efeito da Ginástica Laboral (GL) sobre a dor nas costas e sobre os hábitos posturais de trabalhadores que ficam por longos períodos na posição sentada. Participaram 30 trabalhadores do setor administrativo, divididos em grupo controle (n=15) e grupo experimental (n=15), sendo este submetido a sessões de GL durante três meses. Ambos os grupos foram avaliados por um questionário de dor e postura, sendo as respostas codificadas, tabuladas e submetidas ao teste de Wilcoxon para verificar as diferenças entre pré e pós-experimento (α=0,05). Os resultados demonstraram que a GL proporcionou diminuição da intensidade e frequência da dor referida aos trabalhadores do grupo experimental, e mudança do hábito postural durante o trabalho, melhorando a postura sentada.

Published: March 2020

RESUMO Os antibióticos como o norfloxacino constituem os fármacos mais utilizados na Medicina, com consumos expressivos no mundo todo. Por ser quimicamente estável, após sua administração a maior parte do fármaco é excretada de forma inalterada e, geralmente, é removida apenas parcialmente nas estações de tratamento de esgoto (ETEs). Assim, o presente trabalho buscou avaliar a eficiência dos processos biológicos na remediação de norfloxacino investigando os mecanismos de remoção envolvidos. O objetivo foi verificar a biodegradabilidade do fármaco e sua toxicidade. Para realização dos ensaios de biodegradabilidade, coletaram-se lodos na ETE Arrudas (Sabará, Minas Gerais) dos processos de tratamento com lodos ativados, reatores upflow anaerobic sludge blanket (UASB) e biodigestor anaeróbio. Reatores em escala de bancada foram montados com lodo aclimatado e não aclimatado. Amostras tiveram a biodegradabilidade acompanhada por meio da determinação do carbono orgânico total e da absortividade molar do norfloxacino por espectrofotometria de UV/Vis. Determinou-se a toxicidade por intermédio de ensaios com a bactéria Aliivibrio fischeri. Entre as biomassas utilizadas, a mais eficiente na remoção do norfloxacino foi advinda dos reatores UASB (23%), seguida do biodigestor anaeróbio (18%) e, então, dos lodos ativados (13%). Quanto à ecotoxicidade, a degradação anaeróbia promoveu a eliminação da toxicidade do antibiótico, enquanto com relação à degradação aeróbia os efluentes gerados permanecem tóxicos.

Published: March 2020

Exergames, i.e. games which aim to increase player’s physical activity, are a prominent sub-category of serious games (SGs). Recently, location-based games (LBGs) similar to Pokémon GO have gained the attention of exergame designers as they have been able to reach people who would otherwise not be motivated to exercise. Multiple studies have been conducted on Pokémon GO alone, identifying positive outcomes related to, for example, exercise and social well-being. However, with substantial findings derived from a single game, it is unclear whether the identified benefits of playing Pokémon GO are present in other similar games. In order to broaden the understanding of LBGs as exergames, this study investigates the gameplay features and initial reactions of early adopters to a game called Harry Potter: Wizards Unite (HPWU) which was launched in summer 2019. A questionnaire (N=346) was sent to HPWU players to measure the effects playing the game has on their physical activity. During the first week of play, an increase in mild physical activity was recorded among HPWU players, similar to what has been reported with Pokémon GO. Also almost half of respondents (46,82%) reported to play the game socially, showcasing how LBGs can generally have a positive impactalso on players’ social well-being.

Authors: Zhang Huan , Duan Fan , Li Yang , Wang Qinqin , Lu Xueheng , Gan Xiaohong , Xie Zhenguo , Tang Junfeng
Published: March 2020

Background: Knowledge of plant population structure facilitates conservation, management, and utilization of endangered plants.

Research question: What is the current status of the natural populations of Tetracentron sinense in Leigong Mountain Nature Reserve (LMNR) and what future population development trends can be predicted?

Studied species: Tetracentron sinense  

Study site and period of research: T. sinense populations in LMNR in China in 2018.

Methods: The population structure and quantity dynamics of four typical patches were studied using static life tables, survival curves, survival analyses, and time series analyses. 

Results: The age structures of the T. sinense populations were spindle-shaped, with few seedlings and saplings, and Deevey type II and ? survival curves. The mortality rate ( q x ) of each patch increased quickly, and then plateaued, finally increasing again. Survival rate ( S x ) showed a contrary trend to q x . Trends in cumulative mortality rate ( F (i) ), killing power ( K x ), mortality density ( f (ti) ), and hazard rate ( ? (ti) ) with increasing age class were similar: increasing at a younger age, gradually stabilizing in middle age, and then increasing slightly in older age. The number of individuals in these T. sinense populations was predicted to decrease sharply in future, with younger individuals being seriously deficient. The results showed that the natural populations of T. sinense in the LMNR were relatively stable but were in an early stage of decline. 

Conclusions: The lack of younger individuals might reflect a bottleneck for regeneration of T. sinense populations , leading to a decline in population size.

Antecedentes: Es importante entender las prácticas agrícolas y los criterios de selección que moldean la diversidad de variedades locales en plantas domesticadas. La región andina comparte con la región mesoamericana y Norteamérica los centros de origen de las cinco especies domesticadas de Cucurbita . Sin embargo, los estudios sobre diversidad biológica de estas especies son escasos en Perú en comparación con México.

Preguntas: ¿Cuáles son las variedades locales de Cucurbita que reconocen, promueven y conservan los agricultores en el Distrito de Tomayquichua? ¿Qué mecanismos promueven la diversidad de estas variedades?

Especies estudiadas: Cucurbita ficifolia Bouché, Cucurbita moschata Duchesne, Cucurbita maxima Duchesne.

Sitio y año de estudio: Tomayquichua, Huánuco, Perú (junio de 2018 y 2019).

Métodos: Se realizaron entrevistas semiestructuradas a 29 familias de agricultores y comerciantes para evaluar la diversidad de variedades locales y las prácticas de manejo de las especies del género Cucurbita .

Resultados: C. ficifolia es la cucurbitácea más diversa en Tomayquichua (13 variedades) seguido de C. moschata (10 variedades), las cuales se siembran en chacras y traspatios. Se reportan siete variedades de C. maxima , con el uso predominante de una variedad comercial en cultivos intensivos.

Conclusión: Las prácticas agrícolas tradicionales parecen mantener la diversidad local de C. ficifolia y C. moschata . Las variedades locales de C. maxima en Tomayquichua parecen ser desplazadas progresivamente por una variedad mejorada destinada a aumentar la producción mediante prácticas agrícolas intensivas. La alta diversidad biológica de C. ficifolia en Perú sugiere un origen andino, pero se requieren estudios genéticos adicionales para aclararlo.

Quality assurance in higher education has become an endeavor of global proportions. With the increasing necessity of quality assurance system, the efforts have been initiated within the higher education sector in Mongolia to seek a feasible internal quality assurance system that is in line with the international standards. The main objective of this article is to identify the problems encountered Mongolian higher education system specifically to the implementation of internal quality assurance in HEIs and explore factors that are influential to the implementation of internal quality assurance system of Mongolia. Thus, this article is expected to give recommendations at institutional level by pinpointing the facts that should be taken into account in developing and implementing a workable and effective internal quality assurance system for Mongolian higher education institutions. This article reviewed literatures on the quality assurance systems in higher education area, and determined the current situation and challenges encountered in quality assurance of Mongolian higher education institutions. The findings of the article indicate that the four main issues — the factors influential to the establishment of effective IQA system, quality assurance structure, lack of understanding towards IQA activities and implementation as the view of preparing only for self-evaluation report, and the lack of transparent information system. The article finds that the participation of both external and internal stakeholders in quality assurance process and activities is the key to the development and implementation of an effective internal quality assurance system.

Published: March 2020

The article considers the theoretical model of the creation of a payment bank of the Eurasian Economic Union. The validity of the creation of an issue bank, which at the same time can carry out the functions of a macroregulator of the Eurasian Economic Union, has been stated and proved. The necessity and economic feasibility of creating the union’s own digital fiat currency is substantiated. This will significantly reduce the sanctions pressure on Russia exerted by the United States, releasing Russia's economy from dollar dependence. Clearing based payments can be effected by means of a blockchain.
Information and Value
Authors: Kuligin Vasily
Published: March 2020

The article considers a unit of information as a difference between two things exchanged. The opposite of subjective definitions of value makes exchange mutually beneficial. It reveals the immanent contradiction inherent in the exchanged things, which activates the forces of repulsion and attraction. The identity, difference, and their symmetry, which characterize the interaction of the exchange elements, carry information about their internally inherent structure and organization. It is proved that the information necessary for the agents is born in the process of exchange. It can only be detected in the act of choice. The article traces connection of the information with the energy of interests of the exchange participants, their actions, thoughts, completed and unfinished acts. A conclusion is made about the coordinating role of market prices as a system that brings together the agents’ activities by transmitting knowledge in a simplified form.
Public Policy of Telework Management: Experience of Russia and the USA
Authors: Chudinovskikh Marina
Published: March 2020

The relevance of the research into the issue is determined by the need to develop a state policy in the field of telework management (distance employment). The paper presents an analysis of the practice of state management of telework in the United States of America based on a study of the norms of legislation (Telework Enhancement Act), as well as annual reports submitted to Congress. In the article, general and special scientific methods such as systemic, comparative legal, formal logical, statistical, and others were applied. As a result of the study, it was concluded that the Russian Federation is taking the first steps in the field of managing telework, while in the United States, a comprehensive state policy has been formed and implemented since 2010. The telework state policy includes the development of legal acts, allocation of authority among state and municipal bodies, measures to encourage the creation of remote jobs, the organization of accounting, control and supervision of telework. The implementation of an effective telework state policy has a positive effect on employers, employees, society and the environment. The positive economic effect for the state and government is reduction in operating costs, increase in work efficiency and reduction of staff turnover. For employees, distance employment leads to a reduction in stress and an increase in job satisfaction. The effect for society and the environment is reflected in an increase in the level of public safety, a reduction in the traffic load, pollution of the environment, and energy saving.
‘They might mistake you for an “informant”’
Authors: Lasco Gideon
Published: March 2020

This article is a reflection on doing anthropology in the Philippines amid the government’s punitive antidrug campaign and on the impact of ethnographic research on public discourses on drugs. Using my own ethnographic research as a starting point, I outline how a journal article I published about the lived experiences of young men who use drugs took on renewed significance years later, in a different policy regime. I then outline a research agenda for the anthropology of drug use in the country. Despite the ethical, methodological, and personal challenges of drug-related research, the potential to give voice to ‘hidden populations’ and argue for humane, evidenced-based policies should encourage anthropologists and other social scientists to persevere.

This research aim is to examine the application of guided inquiry learning models and social skills to improve the students' analysis skills. Social studies learning that still uses expository learning models makes students get difficulties to have analysis skills. This study was used the quasi-experimental research that pretest and postest control design. The participants of the study was 132 junior high school students in grade 7th on junior high school. The data collection tools was used Social Skills Rating System (SSRS) adapted from Gresham and Elliot (1990) and tested to the learning outcomes. The research data were analyzed with ANOVA technique. The findings of the research conclude that there are differences in analysis skills of the students who taught guided inquiry learning model and expository learning model. There are differences in analysis skills of the students who have high social skills and low social skills. There is an interaction between guided inquiry learning model and expository learning model when integrated with high social skills and low social skills on analysis skills of the students.

Placing Large Group Relations into Pedestrian Dynamics: Psychological Crowds in Counterflow
Authors: Templeton Anne , Drury John , Philippides Andy
Published: March 2020

Understanding influences on pedestrian movement is important to accurately simulate crowd behaviour, yet little research has explored the psychological factors that influence interactions between large groups in counterflow scenarios. Research from social psychology has demonstrated that social identities can influence the micro-level pedestrian movement of a psychological crowd, yet this has not been extended to explore behaviour when two large psychological groups are co-present. This study investigates how the presence of large groups with different social identities can affect pedestrian behaviour when walking in counterflow. Participants (N = 54) were divided into two groups and primed to have identities as either ‘team A’ or ‘team B’. The trajectories of all participants were tracked to compare the movement of team A when walking alone to when walking in counterflow with team B, based on their i) speed of movement and distance walked, and ii) proximity between participants. In comparison to walking alone, the presence of another group influenced team A to collectively self-organise to reduce their speed and distance walked in order to walk closely together with ingroup members. We discuss the importance of incorporating social identities into pedestrian group dynamics for empirically validated simulations of counterflow scenarios.

Published: March 2020

Objectives: Philip Morris International's heated tobacco product, Marlboro IQOS, is available internationally and soon will be marketed in the United States (US). We examined correlates of curiosity, interest, and likelihood to use IQOS among US young adults. Methods:
Young adults ages 18-30 years (N = 346) were recruited online, viewed a description of IQOS, and completed measures of socio-demographic characteristics, perceived risks, curiosity, interest, and likelihood to use IQOS. Results: Males had greater curiosity, interest, and likelihood
to use IQOS than females. Individuals with household income of $50,000-$75,000 were more curious than those with household income of greater than $75,000. Cigarette smokers, e-cigarette and dual users had greater curiosity, interest, and likelihood of use than non-tobacco
users. Non-white individuals and older young adults had greater likelihood of use. Greater perceived risks of IQOS were negatively associated with curiosity, interest, and likelihood of use. Conclusions: Among young adults, IQOS has greater appeal among males, non-whites, those who

Objectives: In this study, we measured the effects of cigarillo packaging colors and flavor descriptors on appeal and perceived risk among young adults. Methods: United States-based young adults (ages 18-24) recruited via Amazon Mechanical Turk were randomized to view
one of 7 images of cigarillo packages that varied in color (Black and White [B&W], brown, red) and flavor descriptor (none, tobacco, apple). Respondents rated the product's appeal, risk, and addictiveness. Differences in ratings by study condition were assessed using linear regression
models with bootstrapped standard errors. Results: There were 2818 participants, and 26.5% reported having ever used a little cigar or cigarillo. Brown and red packaging were rated as more appealing (vs B&W) across 4 dimensions (all ps < .05). Compared to no flavor descriptor,
tobacco flavor was rated as more "Attention-Grabbing" (b = 0.21, p = .010) and apple flavor was rated higher on all 8 measures of appeal (all ps < .05) and perceived as less addictive (b = -0.13, p = .024). Conclusions: Colors and flavor descriptors on cigarillo packaging increased
appeal and decreased perceived addictiveness. Restricting color and flavor descriptors on packaging may reduce their appeal.

Dünya üzerinde birçok hava olayları, iklimsel değişiklikler ve su kullanımının planlanması hidrolojik döngüden etkilenirler. Su döngüsünün modellenmesi yağış değişkenliği ve taşkın için çok önemlidir. Bu çalışmada Asi Havzasına ait istasyonların 1962-2011 yılları arasındaki hidrometeorolojik parametreleri kullanılarak regresyon analizi yapılmıştır. Havzaya ait parametrelerin birbiriyle oluşturulan kombinasyonları ve akım ile ilişkileri DataFit programı aracılığı ile analiz edilmiştir. Analiz sonucunda en yüksek R², OKH ve KOKH (hata oranları) değerleri incelendiğinde yağış-buharlaşma-akım modeli önerilmiştir. Ayrıca bu parametrelerin trend analizleri parametrik olmayan Mann Kendall Testi ile analiz edilmiştir. Asi Havzasını etkileyen 6 parametre için parametrelerin %85 ve %95 güven aralıklarındaki eğilimleri incelenmiştir.
International Best Practice for Emissions and Fuel Standards: Implementation Possibilities for ASEAN
Authors: Owen Anthony David , Tao Jacqueline Yujia
Published: March 2020

This paper assesses the role that both vehicle emissions and fuel standards can play in moderating the projected increase in emission of pollutants from the road transport sector of Association of Southeast Asian Nations (ASEAN) member countries by adopting international best practice as it currently stands. It concludes that much could be done within ASEAN to align with international best practice in terms of vehicle emission regulations in the transport sector. In addition, exploring alternative fuels such as natural gas, ethanol, and biodiesel could also offer substantial benefits in reducing air pollutants and emissions in the short term as member countries develop their refining capabilities to produce ultra-low sulphur fuel. Until then, it is likely that vehicle emission regulations may be held back at the Euro III (3) level. Despite that limitation, improving existing motorcycle emission regulations could provide abatement possibilities, while also improving local ambient conditions. Recognizing that international best practice is limited for motorcycle emission regulations, ASEAN member countries could play a key role in drafting and possibly shaping such emission standards.

Maize is one of a highly valued crop in the national diet of Ethiopians especially in southern and southeastern regions of the country; it is produces across various agro-ecologies of the country. However, its productivity is constrained by blanket application of mineral nutrients, in particular, nitrogen (N). In this study, we aimed to test site-specific nutrient management supported by precision agriculture tools can provide extension agents and farmers better ways to manage nitrogen, to increase net benefit and reduce environmental pollution. The drastic increase in N fertilizer cost, environmental pollution and increased public scrutiny have encouraged development and implementation of improved N management practices. In this context, on-farm and on-station experiment was conducted during 2014 main cropping season in the central rift valley of Ethiopia. The objective of the study was calibrating N fertilizer rate using the handheld NDVI sensor for efficient management of N to optimize grain productivity. The trials were layout in a randomized complete block design with seven levels of N fertilizer with phosphorus applied uniformly. The study evaluated the relationship between grain yield and NDVI using the handheld Green seeker sensor. The result shows that a strong nonlinear relationship (R2=0.79) were exist between NDVI values and harvest grain yield. In similarly fashion positive exponential relationship (R2=0.71) between INSEY and grain yield during vegetative growth stage six (V6) at both locations. Overall this study shows that the handheld NDVI sensor can be an indicator to better manage N fertilizer application.

Published: March 2020

A short term field study was undertaken to understand ant-plant interaction in Rhizophora mucronata and Avicennia marina of Pondicherry mangroves. Our study revealed that both tree species Rhizophora mucronata and Avicennia marina of Pondicherry mangroves harbor rich and abundant ant fauna. A total of 10 species were recorded belonging to subfamilies Formicinae, Myrmicinae, Dolichoderinae and Pseudomyrmecinae during one season i.e. post monsoon. The abundance of ants was high in Avicennia marina with 9 species of ants and in compared with Rhizophora mucronata with only 7 species. Ants which were only found in Avicennia marina are Oecophylla smaragdina, Polyrchachis simplex, Camponotus sp. The foods for these ants are available as insects’ eggs, scale insects and carcasses of herbivorous insects. The nesting behavior of these ants is also documented. The mutualistic ant-mangrove plants interaction is quite obvious from the field observations and is recorded with relevant photographs from the study area.

Published: March 2020

Smart grid is a new highly integrated power grid which refers to the next generation power grid, with advanced features and two-way flow of electricity and communication. The smart grid is expected to provide real-time information and near instantaneous balance between supply side and demand side. It combines with the advanced information and communication technology such as Wireless Fidelity (Wi-Fi). Wi-Fi is a wireless network technology that allows smart meters and other electronic devices to communicate over a wireless medium. In this paper, we have introduced and modeled a new architecture for a community smart grid, where an information center is established as the controller of the community power grid. Based on this new approach, the potential impact of smart battery, smart metering and renewable energy sources have been studied. Then, we provided an optimal approach for power allocation in the new architecture, which can reduce the power taken from the regular utility even in situations of overloading, and reduce the line loss of power scheduling. Finally, we proposed a methodology to analyze the daily load profile for residential clients with renewable energy resources.

Published: March 2020

Homeless adolescents are at great risk for both victimization and perpetration. The key objectives of the study is to know the nature and causes of victimization and deviant behavior among homeless adolescents in Bangladesh, identify the pattern of victimization particularly in employment sector and in social life and the issues that encourage the homeless adolescents to be involved in deviant behavior. This study is based on descriptive research which found significant information on socio-demographic characteristics of homeless adolescents, involvement in work for earning livelihood at early age, scenery of victimization in working environment, and finally participating in deviant behavior. Homeless adolescents become socially victimized as in most of cases, they have no regular contact with their family, and many adolescent even did not complete their primary education, deprived from basic rights of medical, sports and recreational facility. Furthermore, maximum homeless adolescents are day laborers and are involved in risky employment for long time, getting negligible salary and majority of them are become victim of physical torture and sexual harassment. Besides, most of the homeless adolescents get very harsh behavior from public and large numbers of them are arrested by the police during working. Thus, underprivileged homeless adolescents are become precariously victimized in society. Consequently, most of homeless adolescents are involved in pity offences, became drug abuser and gradually involved with various criminal gangs. So the study finally finds that homeless adolescent are being victimized in different perspective and also being involved with delinquency and serious crimes.
