The purpose of this study is to classify the subtypes of perpetrators of school violence based on their psychological characteristics. In order to classify the students, questionnaires/interviews which consist of 6 factors (Cognitive Impulsivity, Unplanned Impulsivity, Depression, Anxiety, Peer Conformity, and Self assertion) and 19 questions were administered to 86 perpetrators of school violence. Then, a two-step cluster analysis was performed with the survey results of 74 perpetrators. As a result, three clusters were identified and named as follows: 1) Impulsive Vulnerability, 2) Emotional Vulnerability, and 3) Social Vulnerability. Scrutinizing the detailed characteristics of each cluster, the first cluster, Impulsive Vulnerability, showed higher scores on Cognitive Impulsivity and Unplanned Impulsivity, compared to the other two clusters, while Depression and Anxiety scores were lower. The second cluster, Emotional Vulnerability, showed higher scores on Depression and Anxiety, while Cognitive Impulsivity and Unplanned Impulsivity scores were lower. The third cluster, Social Vulnerability, showed the highest score on Peer Conformity among the three clusters. However, Self assertion scores were the lowest in this cluster, and Cognitive Impulsivity, Unplanned Impulsivity, depression, and anxiety scores were lower than in the others. This study will provide a useful insight for facilitating teachers and parents' understanding of the psychological characteristics of school violence perpetrators and thereby contributing to effective intervention.

The purpose of this research is to study the impact of a consulting-recipient company's organizational characteristics have on consulting performance based on a case study of M manufacturing company that received HR consulting. Noticing that the subject company received HR consulting, consulting performance was evaluated in terms of two variables, HR effectiveness and organizational commitment, and the research focused on analyzing HR system improvement and change in awareness of employees. The result showed that all lower factors that describe organizational characteristics - closeness, delegation of responsibilities, ethical management, communication and shared values - had statistically positive impact on HR effectiveness at significance level p<.05. Also, the higher the HR effectiveness, the higher the positive impact on organizational commitment improvement. Moreover, it was shown that all lower factors in organizational characteristics had positive impact on overall consulting performance. Accordingly, the research concludes that, in order to improve consulting performance, i.e., HR effectiveness and organizational commitment, for blue collar workers, the company needs to create a family-oriented and closely-knit working environment, establish rules and systems to delegate responsibilities appropriately, actively promote ethical management and provide strategic activities to facilitate effective communication.

The purpose of the present study was to investigate the mechanism of metabolic partitioning between oxidization and esterification of liver fatty acids synthesized and secreted by the liver from egg yolk-fed laboratory rats. Animals were divided into four groups and orally administered egg yolk daily for 30 days: CON (control group, 1.0 g of saline solution), T1 (1.0 g of pork belly oil), T2 (1.0 g of egg yolk), and T3 (1.0 g of pork belly oil and 1.0 g of egg yolk, alternatively each week). The accumulation rate of [¹⁴C]-labelled lipid in liver was lowest in T2 among all treatments (P<0.05). Phospholipid secretion was higher in T2 than other treatments (P<0.05). The triglycerol secretion was highest in T1 and higher in the order of CON, T3, and T2 (P<0.05). Metabolic partitioning rate of phospholipid from total glycerolipid was highest in T2, followed by T3, CON and T1 (P<0.05). The ¹⁴CO₂ production from total glycerolipid was the highest in T2 and showed a high oxidation rate compared to CON, T1, and T3 (P<0.05). Metabolic partitioning of glycerolipid from the liver decreased in triglycerol of T2 compared to CON, T1, and T3, whereas phospholipids of T2 increased (P<0.05).

This thesis looks closely at the moderating effect of individual variables while we analyzed how corporate's ethics policies have influence on his ethical decision-making behaviors. The subjects of the research were full-time employees (n=211) in the Seoul metropolitan region. The research model was substantiated through statistical analysis of credibility and validity, correlation, variance, and moderated regression analysis (MRA). This study found that within an organization with a code of ethics, the level of enforcement of the code and the level of employee awareness of core values sought by the company determined the level of influence of the code on ethical decision making. In other words, internal factors exerted a greater influence than external evaluation of a corporation's ethical decision making practices and therefore, it is necessary for decision-making practices to be transparent and recognized by the members within an organization. The study also found that the employee's awareness about the long-term visions of the company at a higher level and the employees who have a locus of control to their members internally acted as independent variables as well as control variables on the ethical decision-making. In addition, there were great differences in the level of ethical decision-making among the variables used as controls, which means these differences were related to the individual variables. Accordingly, in order to get ethical decision-making practices at a higher level, a education & training program will be designed and implemented variously as considering on the particular characteristics of the control variables we used in this study.

This study organizational commitment and performance certification could affect vocational trainees for general characteristics of the demographic analysis, and variables according to the learned the difference between organizational commitment, and the result was as follows. First, in males than in females, ages 20s high school education level and marital status were higher in the unmarried than married. Second, vocational training pathways and variance analysis on age 20 in 16 patients (31.4%), 30, 14 (27.5%), 40 (33.3), 50 3 patients (5.9%), 60 1 (2.0%) and were followed in the order of 5-6 hours for a long time trainees prefer to be educated, and female than in male emotional and normative commitment to organizational commitment in the show were high. Ages 40 and an organizational commitment in their 20s and 50s was higher than 30. Qualifications and training satisfaction satisfaction appeared to influence normative commitment certification training influences organizational commitment. However, certification and satisfaction on organizational commitment (-) does not affect the present study showed the figures shown in the policy implications of the authorities gave is preparing to have meaning.

This study was conducted on 236 dental hygienists to find ways to improve patient education by identifying their concern in preventive care, their level of prevention management knowledge, and their impact on patient education by mediating their prevention-related knowledge. It was found that the prevention care concern, prevention knowledge and patient education of dental hygienists have a significant correlation, the higher the prevention care concern, the better the patient education, the better the prevention care knowledge, the better the prevention management knowledge, the better the patient education. The regression analysis and Sobel verification were conducted in order to identify a mediating effect of the preventive care knowledge on the influence that the level of concern on preventive dental care affects the patient education. Therefore, it was confirmed that the level of concern on preventive dental care has not only a direct effect and an indirect effect. Based on the results of this study, it is believed that the preventive education effect of patients will be even higher if institutional support is supported along with the attention of dental hygienists on preventive work and education for preventive knowledge content.

Reactive ion etching (RIE) technique for maskless surface texturing of mc-silicon solar wafers has been applied and succeed in fabricating a grass-like black-silicon with an average reflectance of $4{\pm}1%$ in a wavelength range of 300~1,200 nm. In order to investigate the optimized texturing conditions for mass production of high quantum efficiency solar cell Surface characteristics such as the spatial distribution of average reflectance, micrscopic surface morphology and minority carrier lifetime were monitored for samples from saw-damaged $15.6{\times}15.6\;cm^2$ bare wafer to key-processed wafers as well as the mc-Si solar cells. We observed that RIE textured wafers reveal lower average reflectance along from center to edges by 1% and referred the origin to the non-uniform surface structures with a depth of 2 times deeper and half-maximum width of 3 times. Samples with anti-reflection coating after forming emitter layer also revealed longer minority carrier lifetime by 40% for the edge compared to wafer center due to size effects. As results, mc-Si solar cells with RIE-textured surface also revealed higher efficiency by 2% and better external quantum efficiency by 15% for edge positions with higher height.

Given the rapid development of information and communication technology (ICT) and the deepening of the information gap phenomenon in the context of the COVID-19 pandemic, researchers and practitioners need to understand the changing perceptions of new phenomena such as COVID-19 information gap on the existing information-vulnerable population. In this study, an empirical analysis was performed with the digital information gap survey data in 2020 to understand the potential impact of COVID-19 on the information gap according to the information-vulnerable class. This study is to verify the effect of information gap, marginalized groups, gender, and major factors of information services (contents, social relations, life services, information production, networking, social participation, non-face-to-face services) on the change in perception of digital information technology after Corona. Hierarchical regression analysis was performed. As a result of the analysis, it was found that the higher the content, social relationship, life service, networking, and digital non-face-to-face service, the higher the change in perception of digital information technology after Corona. Therefore, in light of the evolving phenomenon of COVID-19, it is considered that the government needs to provide education and training to strengthen the capabilities of the information-vulnerable class in order to resolve the digital information gap.

This study focuses on the individual characteristics of consumers and creating shared value in relation to recent increasing value consumption. Specifically, it was intended to verify what socio-psychological variables of consumers affect value congruency and product purchase intentions in relation to cosmetics products based on creating shared value activities. In order to verify hypothesis, an online survey was conducted, and the main and mediate effects of the variables were verified through SPSS' Process Macro method. As a result of empirical analysis, the higher the ethical identity, altruism, and consumer effectiveness, the higher the value congruency. Altruism and consumer effectiveness had a positive impact on purchase intentions. We also find that value congruency has a significant mediating effect on the effect of socio-psychological variables on purchase intention. The results of this study provide practical values and implications for companies' need to emphasize consumers' consumption behavior as it can have a significant positive impact on society. It also suggests the importance of finding out what values consumers seek. In other words, this study can provide strategic implications for public relations plans when performing marketing activities by utilizing the values pursued by CSV in companies. Future research will provide strategic implications for promotional measures when marketing is carried out if the consumer's segment is further refined to verify the effectiveness of creating shared value.

This study is a descriptive survey study that applies the planned behavior theory to identify the factors influencing the childbirth intention of unmarried men and women. Data were collected from April 05 to April 23, 2021 for 168 unmarried men and women. As a result of the study, in general characteristics, male, old, highly educated, occupational, and non-regular workers had statistically significantly higher childbirth intentions. As a result of examining the correlation between the variables constituting the theory of planned behavior(TPB), it was found that the more positive the attitude toward childbirth, the greater the subjective norm, and the greater the perceived behavior control, the higher the intention to give birth. Multiple regression analyses showed that the factors affecting fertility intention on men and women. The factors affecting fertility intention in men was attitude, with an explanatory power of 62.2% and the factors affecting fertility intention in women were attitudes and perceived behavioral control, and the explanatory power of these variables on fertility intention was 69.0%. In order to increase the intention to give birth, a comprehensive approach is needed, and the research is meaningful in that the results of this study provided basic data in the development of policies and education programs related to low birth rates in the future.
