The purpose of this study was to examine the effects of depression, sleep, and self-esteem on a dementia preventive behavior in rural elderly people. The participants were 235 elderly people aged 60 or older who lived in J-Gun, J-Do. Data were collected using structured questionnaires and analyzed using t-test, one-way ANOVA, Scheffe test, Pearson correlation coefficients, and stepwise multiple regression with SPSS/WIN 25.0 program. There were significant differences in the dementia preventive behavior according to religion, the level of education, a cohabitation type, an economic level, and dementia education experience. Participants' dementia preventive behavior was positively correlated with self-esteem (r=.52, p<.001) and sleep (r=.31, p<.001). However, it was negatively correlated with depression (r=-.57, p<.001). Factors affecting the dementia preventive behavior were depression, self-esteem, and religion. The explanatory power of variables was 37%. To increase a dementia prevention behavior in rural elderly people, it is necessary to develop dementia prevention programs to reduce depression and improve self-esteem and to create social conditions to facilitate various social participations such as a religious activity.

Purpose: This study aimed to understand how changes in income due to the COVID-19 pandemic have affected the health behavior and mental health status of self-employed individuals. Methods: We compared the health behavior and mental health status of regular wage workers and self-employed individuals with no change in income, with that of self-employed individuals with reduced income due to the spread of COVID-19. Results: Smoking status, average amount of smoking per day, changes in the amount of smoking and drinking due to COVID-19, drinking frequency per year, monthly binge drinking experiences, subjective stress, and suicidal thoughts experienced by self-employed individuals with decreased income were not only higher than those of wage workers and self-employed individuals with maintained income, but their happiness index was also lower than the latter group. Conclusion: This study suggests that the change in total household income due to COVID-19 adversely affects the health behavior and mental health status of self-employed individuals. However, COVID-19-related policies focus only on economic loss compensation, and the health behavior and mental health management for self-employed individuals is insufficient. Therefore, it is necessary to establish policies for health behavior and mental health management of self-employed individuals.

This study sought to confirm the impact of analytical methods and behavioral economic theory factors on decision-making when making chartering decisions in the dry bulk shipping market. This study on chartering decision-making model was began to verify why shipping companies do not make rational decision-making and behavior based on analytical methods such as freight prediction and process of alternative selection in the same market situation. To understand the chartering decision-making model, it is necessary to study the impact of behavioral economic theory such as heuristics, loss aversion, and herding behavior on chartering decision-making. Through AHP analysis, the importance of the method factors relied upon in chartering decision-making. The dependence of the top factors in chartering decision-making was in the following order: market factors, heuristics, internal factors, herding behavior, and loss aversion. Market factors, heuristics, and internal factors. As for detailed factors, spot freight index and empirical intuition were confirmed as the most important factors relied on when making decisions. It was confirmed that empirical intuition is more important than internal analysis, which is an analytical method. This study can be said to be meaningful in that it academically researched and proved the bounded rationality of humans, which cannot be fully rational, and sometimes relies on experience or psychological tendencies, by applying it to the chartering decision-making model in the dry bulk shipping market. It also suggests that in the dry bulk shipping market, which is uncertain and has a high risk of loss due to decision-making, the experience and insight of decision makers have a very important impact on the performance and business profits of the operation part of shipping companies. Even though chartering are a decision-making field that requires judgment and intuition based on heuristics, decision-makers need to be aware of this decision-making model in order to reduce repeated mistakes of deciding contrary to market situation. It also suggests that there is a need to internally research analytical methods and procedures that can complement heuristics such as empirical intuition.

The purpose of this study was to examine the health knowledge, attitude and behaviors of Korea high school students and find out the relationship between knowledge, attitude and behaviors in an effort to lay the foundation for the development of health-promotion programs and health education for adolescents. The subjects were 505 students in their first and second year of high school in Gangnam-gu and Guro-gu, Seoul. After a survey was conducted for seventeen days from April 23 to May 9, 2003, with self-administered questionnaires, the collected data was encoded and analyzed with SPSS Win 11.0 program. The frequency, percentage, mean and standard deviation were calculated, and χ²-test, t-test, ANOVA, Scheffe Post Hoc Tests and Pearson Correlation procedure were employed. The findings of this study were as follows： 1. There appeared significant differences in general traits, family-related characteristics and health-related features between the students in Gangnam and the others in Guro. 2. The collective average of the Gangnam residents in health knowledge was 13.97, and that of the Guro residents was 14.64. The overall collective average was 14.35(total of 22 points), and 65.2 percent of the students investigated had a correct knowledge. The points showed significant differences in the variables of sex, economic status, mother's occupation,and health concerns. 3. The students from Gangnam scored a mean of 77.55 in health attitude, and the others from Guro got an average of 78.75. The overall collective average was 78.22(total of 110 points), and 71.1 percent took a correct attitude toward health. The points showed significant differences in the variables of sex, religion, mother's education level, health concerns. 4. In the field of health behavior, the Gangnam residents got a mean of 63.99, and the Guro dwellers scored a mean of 62.12. There was a significant gap between the two groups, and the overall collective average was 62.94(total of 102 points). 61.5 percent tried to stay fit in a correct behavior. The points showed significant differences in the variables of sex, economic status, parents' education level, father's occupation, health concern of parents, self-perceived health status, health concern, exercise or diet performance for health, health education times for 1yr. 5. Concerning the relationship of health knowledge to health attitude and behavior, the health knowledge showed significantly positive correlation with health attitude(r＝0.227, p＜0.01), and the health knowledge showed significantly positive correlation with health behavior(r＝0.262, p＜0.001). But their relationship is comparatively low. The health attitude was not significantly correlated to health behavior.

Purpose - Currently, strengthening small and medium-sized enterprises (SME) in terms of competitiveness is a key economic issue. However, the problem is that many SMEs lack the internal competence required to cope with a rapidly changing market structure. Such problems can act as an obstacle to economic development, yet most SMEs in Korea are dealing with this problem today. A company's source of competitive advantage is changing from quantity to quality, facility to knowledge, and hardwork to creativity. Under such circumstances, a company should place learning and sharing of knowledge and continuously creating new knowledge as its priority. This study aims to identify the effect of a chief executive officer's (CEO) compassion and forgiveness - positive factors in organizational emotion - on learning organization activities and organizational performance, through a theoretical comparison. Research design, data, and methodology - For this study, SMEs based in Daejeon and Chungcheong area were selected. To secure credibility of the data, the subjects were selected among those who have been working at the business for six months or longer. The survey was conducted for 30 days from March 5, 2015 to April 5, 2015. Both offline and online surveys were conducted. Fifty companies were chosen and 700 questionnaires were distributed, with 506 used for analysis. Fifty subject companies (25 from Daejeon, 10 from Chungnam, 10 from Chungbuk, and five from Sejong) were selected and the objective, target, and survey content were explained to a manager at each company either face-to-face or on the phone. Of the total of 700 questionnaires distributed via mail or e-mail, 78.6% or 550 copies were returned. Excluding 44 insufficient questionnaires, the remainder, 506 questionnaires, were used for analysis. Results - This study analyzed how the CEO's compassion and forgiveness affects learning organization activities and organizational performance. First, compassion of the CEO at the SMEs directly affected the learning organization activities and indirectly affected the organizational performance. Second, forgiveness of the CEO at the SMEs did not affect the learning organization activities and organizational performance directly or indirectly. Conclusions - The study conclusions are as follows. First, CEO compassionate behavior at the SMEs was a significant variable that directly and indirectly affected learning organization activities and organizational performance. Therefore, the CEO of an SME can create a positive organizational atmosphere through compassionate behaviors in the organization. Second, the forgiving behavior of the CEO did not have direct or indirect effects on learning organization activities and organizational performance. However, the reason for a CEO to continue his or her forgiving behavior is because it strengthens employee resilience, commitment, and self-efficacy to protect the organization from negative influences such as layoffs, risks, and wrongdoings. The action of forgiveness does not have direct or indirect effects. However, the CEO shall continue such behavior to strengthen members' physiological resilience, commitment, and self - effectiveness, and to protect the organization from risks including layoff and external negative factors.

The effects of joint density and size distribution on the hydrogeologic characteristics of jointed rock masses are addressed through numerical experiments based on the 2-D DFN (discrete fracture network) fluid flow analysis. Using two joint sets, a total of 51 2-D joint network system were generated with various joint density and size distribution. Twelve fluid flow directions were chosen every $30^{\circ}$ starting at $0^{\circ}$, and total of 612 $20m{\times}20m$ DFN blocks were prepared to calculate the directional block conductivity. Also, the theoretical block conductivity, principal conductivity tensor and average block conductivity for each generated joint network system were determined. The directional block conductivity and chance for the equivalent continuum behavior of the 2-D DFN system were found to increase with the increase of joint density or size distribution. However, the anisotropy of block hydraulic conductivity increases with the increase of density discrepancy between the joint sets, and the chance for the equivalent continuum behavior were found to decrease. The smaller the intersection angle of the two joint sets, the more the equivalent continuum behavior were affected by the change of joint density and size distribution. Even though the intersection angle is small enough that it is difficult to have equivalent continuum behavior, the chance for anisotropic equivalent continuum behavior increases as joint density or size distribution increases.

This experiment was carried out to determine the effect of breed and sex on behavioral characteristics and economic traits of performance-tested pigs. Totally 32 tested pigs in 4 different breeds were assigned for behavioral observation. Behavior was recorded for 4 hours(each 2 hours, before and after none) of tested pigs in each tested pen. The average daily gain, age at 90 kg and feed efficiency on the basis of the performance data were collected from 8,477 performance-tested pigs in which pure breeds of Duroc, Yorkshire, Landrace and Berkshire at the Korea Swine Testing Station. The results obtained in this study are summarized as follows; The effect of breed was statistically significant for all traits studied. Average daily gain were the highest(P<0.05) in Duroc and ages at 90 kg were the highest(P<0.05) in Berkshire. In feed efficiency of male, Landrace and Yorkshire were the most efficient. The average daily gain and feed efficiency were superior to those of female, however, the age at 90 kg was not different. Overally, females were superior to males in various traits examined. Berkshire breed had more proportion of time spent in ventral tying and sitting whereas the proportion of time spent in walking, drinking and eating was less than that of other breeds. The male pigs showed more time spent in standing and social behavior.
