Production mechanism and characteristics of dissolved organic nitrogen derived from soluble microbial products (SMPs-DON) in a drinking water biological aerated filter
Authors: Kang Jia , Liu Shu-li , Ma Teng-fei , Gao Xu
Published: May 2019

Dissolved organic nitrogen derived from soluble microbial products (SMPs-DON) generated during the drinking water biological treatment process poses a great threat to water supply safety due to the potential carcinogenic risk. To further study the production mechanism and characteristics of SMPs-DON in drinking water biological aerated filtration (BAF), Illumina MiSeq sequencing is applied to characterize the microbial community. In addition, an excitation–emission matrix combined with the parallel factor model (EEM-PARAFAC) and gel filtration chromatography (GFC) are used to analyze the component and molecular weight (MW) distribution of the SMPs-DON. Results showed that the production of SMPs-DON in drinking water BAF can be explained using Illumina MiSeq sequencing from the perspective of the microbial community. Also, according to the EEM-PARAFAC analysis, the fluorescence intensity scores of fulvic-like and humic-like substances were almost unchanged, whereas the scores of protein-like substances first increased and then decreased, which was consistent with the variation in the DON concentration. SMPs produced initially primarily consisted of macromolecules with MW >20 kDa, and then they were degraded and small molecular SMPs with MW <5 kDa accumulated. This study provides theoretical guidance and technical support for ensuring drinking water safety and reducing secondary pollution risks from drinking water biological treatment.
The Use of Social Media by Dental Students for Communication and Learning: Two Viewpoints
Authors: de Peralta Tracy L. , Farrior O. Fields , Flake Natasha M. , Gallagher Desmond , Susin Cristiano , Valenza John
Published: May 2019

Social media have become a major part of an interconnected society, impacting personal and professional lives. This Point/Counterpoint presents two opposing viewpoints on the question of whether social media should be used in dental education as a learning and communication tool for dental students. Viewpoint 1 argues that social media benefit student learning and should be used as a tool in dental education. This argument is based on evidence concerning use of social media and improved learning across health professions, improved peer‐peer communication in clinical education, improved engagement in interprofessional education (IPE), and provision of a mechanism for safe and improved communication between practitioners and patients, as well as faculty and students. Viewpoint 2 argues that potential problems and risks in using social media outweigh any benefits found in learning and therefore social media should not be used as a tool in dental education. This viewpoint is supported by evidence of negative effects on learning, the establishment of a negative digital footprint in the public's view, risk of privacy violations when using social media, and the new phenomenon of Internet addiction with its negative physiological effects on social media users.
Applications for self-monitoring of gestational diabetes mellitus in pregnancy; part of the improvement of connected health in Europe (Preprint)
Authors: Drusany Starič Kristina , Trajkovik Vladimir , Belani Hrvoje , Bukovec Petra
Published: May 2019

BACKGROUND

The rapid development of mobile application technology and personalized medicine also in Europe, stimulate the self-monitoring. Self-monitoring allows the patient to actively participate in the treatment process, with a positive impact on the result of the treatment. Mobile applications thus offer a new way to promote healthy behaviors, such as healthy diet, physical activity and measurement of blood glucose levels in the care for women with gestational diabetes. However, there are many factors, which make significant barriers preventing wide use of mobile applications in general medical praxis.

OBJECTIVE

The main aim of this study is to evaluate the most commonly used mobile apps used to manage gestational diabetes and compare them to each other.

METHODS

This paper presents a study, which investigates the mobile applications that can potentially support controlling of the blood sugar in pregnant women. After a broad overview of mobile applications on the Google Play Store and iTunes, we found 90 mobile applications that fit our keywords search terms and our inclusion criteria. Among these 90 applications, only 4 were designed for the management of gestational diabetes and not diabetes in general. All 4 were downloaded and analysed. Among the rest 86 applications that were designed to manage diabetes in general we downloaded, evaluated and compared to each other 5 applications with the highest download rate.

RESULTS

The characteristics of the most commonly used applications were described. Differentiations between useful mobile applications were investigated.

CONCLUSIONS

Applications can provide support for women to act on a certain issue by themselves without visiting an obstetrician. Although most of the applications were very useful, we suggested improvements. The greatest policy concerns of connected health are quality, privacy and safety of the gathered data.
Leaderboard Design Principles to Enhance Learning and Motivation in a Gamified Educational Environment: Development Study (Preprint)
Authors: Park Sungjin , Kim Sangkyun
Published: May 2019

BACKGROUND

Gamification in education enhances learners’ motivation, problem-solving abilities, decision-making abilities, and social skills such as communication. Numerous ongoing studies are examining the application of gamification design methodology and game mechanics to a learning environment. Leaderboards are a type of game mechanic that assist learners in goal setting and unleash the motivation for learning.

OBJECTIVE

The aim of this study was to develop leaderboard design principles to assist learners in efficient goal setting, improve learning motivation, and promote learning in gamified learning environments.

METHODS

This study implemented 2 different strategies. First, we analyzed previous research on leaderboards that focus on educational efficacy and influence on social interactions. Second, we collected and analyzed data related to cases of leaderboards being used in educational and sport environments.

RESULTS

This study determined 4 leaderboard design objectives from previous studies. Based on these objectives, we developed 3 leaderboard design principles. First, macro leaderboards and micro leaderboards should be designed and used together. Second, all the elements used to measure learners’ achievements in an educational environment should be incorporated into the micro leaderboard. Third, leaderboards should be designed and considered for application in contexts other than learning environments. This study further analyzes best practices considering the 3 leaderboard design principles.

CONCLUSIONS

This study contributes toward resolving problems associated with leaderboard design for the application of gamification in educational environments. Based upon our results, we strongly suggest that when teachers consider applying gamification in classrooms, the leaderboard design principles suggested in this research should be incorporated.
Is routine baseline brain imaging needed for all newly diagnosed non-small-cell lung cancer patients?
Authors: Abdel-Rahman Omar
Published: May 2019

Aim:Dedicated brain imaging is advocated by the National Comprehensive Cancer Network guidelines for newly diagnosed non-small-cell cancer (NSCLC) patients beyond stage I. The current study assessed the performance characteristics of this recommendation.Methods:Through accessing the Surveillance, Epidemiology and End Points (SEER) registry (2010–2015), all patients (regardless of stage) with newly diagnosed NSCLC and complete information about TN stages and presence or absence of brain metastases were extracted. In the current study, the following performance characteristics of the above recommendation were assessed: sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), number needed to investigate (NNI) and accuracy.Results:A total of 182,977 NSCLC patients were included. For the overall cohort, PPV (for the recognition of brain metastases) was 13.8% and NNI to detect one case of brain metastasis was 7.2. Likewise, NPV (for the exclusion of brain metastases) was 97%, sensitivity was 92.1%, specificity was 31.1% and overall accuracy was 37.6%. When stratified by histology, patients with adenocarcinoma have PPV of 17.2% and NNI to detect one case with brain metastasis of 5.8. NPV (for the exclusion of brain metastases) was 97%, sensitivity of 91.4%, specificity of 35.4% and overall accuracy of 32.6%. On the other hand, patients with squamous cell carcinoma have PPV of 6.3% and NNI to detect one case with brain metastasis of 15.8. NPV (for the exclusion of brain metastases) was 98.9%, sensitivity of 94.6%, specificity of 26.3% and overall accuracy of 29.7%.Conclusion:In view of the poor specificity, the current study calls for reconsideration of the universal recommendation of dedicated brain imaging (in addition to PET/CT scan) among NSCLC patients beyond stage I.

Evolution of corporate governance towards intrinsic value
Authors: Grove Hugh , Lockhart James C.
Published: May 2019

The major research question addressed by this paper is how to evolve corporate governance beyond its traditional shareholder focus towards the broader perspective of a stakeholder focus with intrinsic value. Intrinsic value refers to the monetary value of a company, stock, currency, or product determined by fundamental analysis, without reference to extant market value. It is ordinarily calculated by summing the discounted future income generated by the company, stock, currency or product to obtain its present value. In this paper we observe the evolution of corporate governance towards an intrinsic, long-term value focus by the boards of directors, corporate executives, owners and shareholders, regulators and legislators, and other stakeholders. These major players are encouraged to develop more wisdom in order to assess the emerging threats, challenges, and opportunities from technology for intrinsic value, especially with the perspective of the public corporation as a separate legal personhood, as advocated by the European Parliament’s Committee on Legal Affairs in 2015. The rapid increase in the development of artificial intelligence (AI) and other technologies has tremendous significance for these major players broadly contributing to effective corporate governance. To facilitate the development and evolution of intrinsic value for public corporations and other entities, these major players need wisdom for more effective corporate governance in challenging times. Accordingly, this paper discusses the evolution of corporate governance and board members’ perspectives from a shareholder focus to a stakeholder focus with intrinsic value; the key success factor being wisdom for boards; the three-dimensional wisdom scale; and, the AI challenge, including the “Deadly Soul” of a new machine, to the wisdom of company executives and their boards of directors.

Authors: Li Yan , Sun Ce , Jiang Yu , Yi Xian , Zhang Yingwei
Published: May 2019

To research the law of the icing accretes on near the tip part of rotating blade of large-scale horizontal axis wind turbine (HAWT) influenced by liquid water content (LWC), the icing distribution on a HAWT rotor with rated power of 1.5 MW was simulated based on a Quasi-3D computation method. About 30% part length of blade from tip along span wise to blade root which are the most serious icing area was selected to research. Eight sections of this 30% part were decided and the ice distribution on each sections were simulated. Five kinds of LWC from 0.2 g/m3 to 1.4 g/m3 and two kinds of temperatures including ?6?C and ?18?C were selected. The medium volume droplet is 30 mm. Three kinds of icing time were selected to analyze the effects of icing time on ice accretion. The icing shape evaluate method was applied to quantitatively analyze the icing shape obtatined under different conditions. The results show that the icing shapes are all horn icing shape under the different LWC when the temperature is ?6?C. The icing shapes change from horn icing shape to streamline icing shape with LWC increasing under the temperature of ?18?C. The icing accretes on blade surface layer by layer with icing time increasing. The closer the section blade tip, the more icing accretes. This study can be as reference for the research on anti-icing and de-icing technologies for large-scale HAWT.

Authors: Guo Jingna , Liu Jiangfeng , Li Qiang , Xu Chen , Chen Zhanqing , Huang Bingxiang , Chen Shuliang
Published: May 2019

In the excavation process, the coal pillar will undergo shear failure due to repeated loading and unloading from mining stress. Meanwhile, plastic flow will occur after shear failure. The permeability change of the coal pillar under plastic flow is closely related to the loading path. Through a permeability test of the coal sample after shear yielding under cyclic loading and unloading conditions, the variation law of permeability of a coal seam under plastic flow was obtained. The results show that the permeability of the coal sample increases as the axial strain decreases during the unloading phase. During the loading phase, as the axial strain increases, the permeability of the coal sample decreases. Scanning electron microscope tests show that the crack opening is larger at lower confining pressures. As the confining pressure increases, the crack opening decreases and moves toward the middle of the sample.
Exploration of work motivation structure and profiles based on self-determination theory among Korean employees
Authors: Park JiHyeon , Chang JaeYoon
Published: May 2019

The Self-determination theory (SDT) posits the existence of distinct taxonomy of motivation (i.e., amotivation, external, introjected, identified, integrated, and intrinsic motivation). The purpose of this study was to explore whether SDT’s work motivation structure can be applied to the understanding that of Korean employees, and to identify the motivational profiles for Korean employees together with their relationships with a variety of organizational outcomes. Data was collected from two separate samples of Korean employees(Study 1: 509 employees; Study 2: 153 employees). The results showed that unlike SDT taxonomy, autonomous motivations were not classified into three distinctive categories(identified, integrated, and intrinsic motivation). The results also revealed that there were three distinct motivational profiles(i.e., autonomous motivated, controlled motivated, and amotivated), and the largest proportion of Korean employees was covered by controlled motivated cluster. The autonomous motivated cluster had the most favorable levels of adaptive organizational outcomes(i.e., organizational commitment, job satisfaction), whereas the amotivated cluster was strongly related to non-adoptive organizational outcomes(i.e., turnover, emotional exhaustion). Based on these results, discussion was made regarding the distinct features of work motivation structure and motivational profiles in Korean work setting, and also future research directions were suggested.

The current study explored structural relationships of ego-resilience, affect experience, meaning in life, and job satisfaction. Also, this study examined the moderating effects of transformational leadership between affect experience and meaning in life meaning. We collected data from 730 soldiers working at ROK Air Force air wing located at Gyeonggi-do. The results from mediation analysis showed that positive and negative affect mediated between ego-resilience and meaning in life, respectively. Also, meaning in life mediated between positive and negative affect, and job satisfaction, respectively. The results from regression analysis reported that transformational leadership moderated between positive and negative affect, and meaning in life, respectively. Additionally, transformational leadership moderated the mediation effects between positive and negative affect, and job satisfaction, respectively. In the discussion section, we discussed about theoretical and practical implications of this study.

Authors: Park SunHee , Lee JeeYoung
Published: May 2019

This study examined the effect of interpersonal character strength of service employees on their emotional aspect of happiness. Interpersonal character strength has been shown to be a critical skillset required for service encounter employees, thus is expected to increase the levels of employee happiness, as well as to moderate the relationship between emotional labor strategies (e.g. deep acting and surface acting) that employees useand their positive emotion. The results from a sample of 129 receptionists working at imported electronics show rooms and service centers showed that interpersonal character strength indeed had a significant positive effecton happiness, even after controlling demographic variables and other character strengths. Furthermore, interpersonal character strength moderated the relationship between deep acting and happiness so that emotional laborers with high interpersonal character strength experienced more positive emotion when using deep acting strategy, as compared to those with low interpersonal character strength. These findings offer suggestions for organizations and their employees to develop both deep acting strategy and interpersonal character strength in order to enhance the level of happiness of employees.

Authors: Ko YeYoung , Yoo TaeYong
Published: May 2019

The first purpose of this study was to investigate the effects of self-development motive and impression management motive on continuous learning activity. The second purpose was to examine the mediating effects of feedback seeking behavior on the relationship between two motives(self-development motive, impression management motive) and continuous learning activity. The third purpose was to testify the moderating effects of the leader-member exchange quality on the two motives(self-development motive, impression management motive) and feedback seeking behavior. Using the survey research method, data were collected from 239 employees who were working in a variety of organizations in Korea. The results of this study showed that self- development motive was positively related to continuous learning activity, whereas impression management motive was not positively related to continuous learning activity. The self-development motive and impression management motive were positively related to feedback seeking behavior and feedback seeking behavior was positively related to continuous learning activity. Therefore, feedback seeking behavior had partial mediation effect on the relationship between self-development motive and continuous learning activity, and feedback seeking behavior had full mediation effect on the relationship between impression management motive and continuous learning activity. Finally, leader-member exchange(LMX) quality had moderation effect on the relationship between impression management motive and feedback seeking behavior. Specifically, the positive relationship between impression management motive and feedback seeking behavior was stronger when LMX quality was high than low. Based on these results, we discussed the implications and limitations of the study, and the suggestions for the future research.
Development of the Korean culture adjustment scale for Chinese workers in Korea and exploration into the different internal structure of Korean Chinese and Han Chinese
Authors: Gao Qinghua , Yoon Jungmee , Lee Soonmook , Lee Bitna
Published: May 2019

This study was conducted to develop a scale which can measure the Korean culture adjustment of Chinese workers employed in Korea. In the study 1, we selected 4 sub-dimensions and 24 questions that measure the characteristics of Korean culture adjustment through literature review and in-depth interviews. In the study 2, we conducted surveys on 405 Chinese workers to verify the constructs of the Korean culture adjustment scale. Subjects were divided into the two groups of Korean Chinese and Han Chinese, exploratory analysis was conducted in Exploratory Structure Equation Model frame. If sub-divisions are observed by group, the Korean Chinese group showed a 3 dimensional (adjustment to occupational environments, adjustment to living environments, psychological adjustment) structure and the Han Chinese showed a 4 dimensional (adjustment to occupational environments, adjustment to living environments, psychological adjustment, communicational adjustment) structure. In particular, communicational adjustment was a factor drawn only from the Han Chinese through factor analysis. This implied that the reason is because the language used by the Korean Chinese is similar to the Korean language. In the study 3, multi-group analysis was performed to observe whether a measurement model of the Korean culture adjustment scale can generalize or differentiate between groups. As a result, equal interpretation between groups was possible for questions forming coidentity. The Korean culture adjustment scale developed in this study is significant in that it can assess the unique Korean culture adjustment of Chinese workers.
The relation between calling and career adaptability
Authors: Min Jihyun J , Kang Esther , Lee Hyejoo J
Published: May 2019

One’s calling can be divided into cognitive (“perceiving a calling”) and applied phases (“living a calling”), with the latter involving the execution of the former in life. We examined if living a calling moderate the relation between perceiving a calling and career adaptability. We hypothesized that the relation between perceiving a calling and career adaptability will differ according to the degree of calling execution by employees. However, for currently unemployed college students, we hypothesized that the level of calling execution would not influence the aforementioned relationship because they would have fewer opportunities for executing their perceived calling. The study results with 392 adult professionals and 248 college students indicated that living a calling significantly moderated the relation between perceiving a calling and career adaptability, in both adults and students but in opposite direction. Thus, whether one has a job or not, living a calling affect the relationship between perceiving a calling and career adaptability.

Authors: Jeon Sohyun , Chang JaeYoon , Lee HyeJoo
Published: May 2019

The purpose of this study was to examine the channeling model to investigate the interaction effect of implicit measure (Conditional Reasoning Test for Aggression: CRT-A) and self-reported measure of aggression to predict helping behavior. Expatriates who were dispatched to China or India (N=101) participated in this study. To reduce the common method bias, their host country co-workers (N=320) evaluated the expatriates’ helping behavior as a behavioral criterion. The results showed that there was a significance difference in helping behavior among the expatriates who had high CRT-A scores. Specifically, latent aggressive individuals who consciously perceived themselves as being non-aggressive but implicitly rationalized their aggressive behavior were less likely to show helping behavior. The academic implications of the current study, along with suggestions for the future research, were discussed.

Authors: Malik Muhammad Shaukat , Sattar Shahzadi
Published: May 2019

The purpose of this research study has been to examine the relationship between despotic leadership, emotional exhaustion and sexual harassment in the presence of organizational cynicism as the moderator. The above-mentioned relationships were empirically tested by collecting and analyzing the data from the government sector hospitals in Pakistan. The target respondents were female nurses working in the six different hospitals of Multan and Bahawalpur region. The sample of 350 nurses was randomly chosen to collect the data. The results of the study proved the positive effect of despotic leadership with the employee emotional exhaustion. The other relation, which is proved, is the significant positive relationship between sexual harassment and the emotional exhaustion in the presence of organizational cynicism as the moderator. Based on the social exchange theory it is inferred that a reciprocal relationship exists in the organizational context between the leaders and the subordinates when the trauma and depression is lent to the subordinates the subordinates feel emotionally deteriorated.
Is Entamoeba Gingivalis a Risk Factor for Periodontal Diseases? A Case-Control Study
Authors: Hassan Sandy Shabaan , Madkour Gihane Gharib , Henin Ramy Wahba , Gad Selvia Wahib Fayek , Abd El-Aal Amany Ahmed
Published: May 2019

Background: Entamoeba gingivalis was the first commensal parasite detected in the oral cavity of humans, and a high incidence has been reported in patients with poor oral hygiene. The current study aimed to investigate the association of Entamoeba gingivalis with gingivitis and periodontitis among Egyptian subjects. Methods: A total of 120 plaque samples were collected for this case-control study and were divided as follows: 40 plaque samples from gingivitis patients (group 1), 40 from stage II grade A and B periodontitis patients (group 2), and 40 samples from healthy volunteers (group 3). Diagnosis of parasitic stages relied on direct microscopic detection using permanent stains, trichrome stain, and hematoxylin and eosin (H&E) stain, in addition to ocular micrometry to confirm the diagnosis. Results: The occurrence of Entamoeba gingivalis within the gingivitis group was significantly higher (40%) than that observed in the control group (22.5%), whereas the occurrence within the periodontitis group was 15%. Samples from diseased subjects, regardless of immune status, were found to be moderately to severely affected with numerous parasitic nests, in contrast to a moderate near mild occurrence that was recorded in the healthy control group. Moreover, Entamoeba gingivalis occurrence was significantly higher (77.4%) in subjects with bad oral hygiene. Conclusion: The results of the present study suggest a potential role for the neglected oral parasitic Entamoeba gingivalis, especially the intensively multiplying forms, in the pathogenesis of periodontal diseases. This certainly needs further elucidation on a larger scale to explore the basis behind such multiplication, which may be related to genetic variation or may be pathophysiological in origin.

Quantitative Analysis of Ciprofloxacin in an Ophthalmic Solution Using UV Absorption Spectrophotometry and Derivative Spectrophotometry
Authors: DERMİŞ Saadet , KILIÇ Sümeyye , ERTEKİN Zehra Ceren , DİNÇ Erdal
Published: May 2019

The
quantitative analysis of ciprofloxacin in an ophthalmic solution was performed
by UV absorption spectrophotometry and first derivative spectrophotometry. The
UV absorption spectra of standard series and samples containing ciprofloxacin
were recorded. Then, the derivative of UV absorption spectra was obtained for
the derivative spectrophotometric analysis of the related drug.  Linear regression equations in the linear concentration
range of 3.0-28.0 µg/mL for analysis of ciprofloxacin were obtained by using
direct absorbance measurement at 278.9 nm and using the dA/dλ values at 283.2
nm. The recovery assay results were found between 97.8 to 102.0 %. It was
observed that the limits of detection and quantification were 0.74 and 2.74
μg/mL for UV absorption spectrophotometry and 0.60 and 2.00 μg/mL for first
derivative spectrophotometry, respectively. Analysis results indicated that the
proposed methods were precise, accurate and reliable for the determination of
ciprofloxacin in commercial samples.
Calculation of Production Reaction Cross Section of Some Radiopharmaceuticals Used in Nuclear Medicine by New Density Dependent Parameters
Authors: KAVUN Yusuf , TEL Eyyup , ŞAHAN Muhittin , SALAN Ahmet
Published: May 2019

In
nuclear medicine, radiopharmaceuticals are used for diagnosis or treatment
purposes. Radiopharmaceuticals containing radionuclide in their structure are
produced by reactors, generators or cyclotrons and are generally used for scintigraphy
or tomographic investigations. The produced radionuclides can be given to the
human body together with organic or inorganic substances.  In this study, 
the production reaction cross sections were calculated for two selected
radiopharmaceutical nuclei (99Tc and 115In) using the semi-empirical cross section formula for the (n, α) reactions developed by Tel et al. (2008).
The density depending on (n, α) reaction cross sections were also investigated with
the four Skyrme Hartree Fock parameters (S3, T3, SKM and SKM*). While the calculated
value from the semi-empirical formula
developed by Tel et al. (2008) gave reasonable results, the density-dependent
calculations were observed lower values than that of experimental values.

What Is the Potential for Applying Cost-Utility Analysis to Facilitate Evidence-Based Decision Making in Schools?
Authors: Hollands Fiona , Pan Yilin , Escueta Maya
Published: May 2019

Education decision makers routinely make choices among programs and strategies to implement. Policy demands increasingly require that such decisions are based on evidence regarding program effectiveness at improving student outcomes. However, research evidence is but one of the considerations that practitioners must juggle, along with local conditions, capacity, resource availability, and stakeholder values. We investigated the feasibility of applying a multicriteria decision-making framework based on cost-utility analysis to facilitate evidence-based decisions by educators. Working with a total of 183 aspiring school leaders in class settings, we determined to what extent they could implement the initial steps of the framework. We subsequently invited three educators to apply the full framework to substantive decisions in their schools and report the results.
Teaching Academically Underprepared Postsecondary Students
Authors: Perin Dolores , Holschuh Jodi Patrick
Published: May 2019

Only 25% to 38% of secondary education graduates in the United States are proficient readers or writers but many continue to postsecondary education, where they take developmental education courses designed to help them improve their basic academic skills. However, outcomes are poor for this population, and one problem may be that approaches to teaching need to change. This chapter discusses approaches to the teaching of academically underprepared postsecondary students and how teaching might be changed to improve student outcomes. A wide variety of approaches is reported in the literature, including teaching of discrete skills, providing strategy instruction, incorporating new and multiple literacies, employing disciplinary and contextualized approaches, using digital technology, and integrating reading and writing instruction. However, the field has yet to develop a clear theoretical framework or body of literature pointing to how teaching in this area might improve. Based on our reading of the literature, we recommend directions for future research that could inform changes in the teaching of underprepared students at the postsecondary level.
