The coastal village in Woljeong-ri, Jeju is highly preferred by tourists because of its unique natural landscape different from inland areas. Especially, the number of buildings in the coastal area of the village is increasing due to escalating commercial value. Buildings are densely developed, along the seaside, resulting in privatization of coastal landscape. This results in blocking of landscape and psychological exchanges between the coastal village and coast. This study analyzed the actual conditions of coastal landscape before and after 2010, when the number of tourists and demand for development were increased in the coastal area of the coastal village in Woljeong-ri, Jeju. In this study, open index, visible horizontal index, elevation angle, elevation blockage and visible facade index were used to compute objective indicators of coastal landscape status. The analysis reveals visible facade index, a complex landscape assessment indicator, was increased by 7 times after 2010 as compared with before 2010. As such, there are many coastal villages in Jeju similar to Woljeong-ri that have a high landscape value and are in need of management. A comprehensive measure including a system for management of coastal landscape is urgently required to create narrative landscape in Jeju.

Objectives : The study is performed to investigate the influence of psychological stress on neck muscles tone and heart rate variability(HRV). Methods : This study was carried out with the data from stress response index score(SRI), surface electromyography(sEMG) and HRV. First subjects were divided into two group according to the SRI points. Subjects in group A had points of SRI in which lower than 30 points. Subjects in group B had points of SRI in which higher than 30 points. Then we investigated how to difference of the index of sEMG and HRV according to each groups. Results : In this study, the muscle contraction of both upper trapezius muscle in stress group were higher than non-stress group significantly. Complexity, root mean square of successive differences of R-R intervals(RMSSD), standard deviation difference between adjacent normal to normal intervals(SDSD), high frequency oscillation power(Ln(HF)), normalized HF(Norm HF) in stress group were lower than non-stress group significantly and normalized LF(Norm LF) was higher. Conclusions : This results show that the stress was associated with neck muscle condition and autonomic nervous system.

Purpose: This paper aims to assess psychological heuristics' effectiveness on cumulative returns after significant stock price changes. Specifically, it compares availability and anchoring heuristics' empirical validity due to conflicting stock return predictions. Research Design, Data, and Methodology: This paper analyzes stock price changes of Korean distribution industry stocks in the KOSPI market from January 2004 to July 2022, where daily fluctuations exceed 10%. It evaluates availability heuristics using daily KOSPI index changes and tests anchoring heuristics using 52-week high and low stock prices as reference points. Results: As a result of the empirical analysis, stock price reversals did not consistently appear alongside changes in the daily KOSPI index. By contrast, stock price drifts consistently appeared around the 52-week highest stock price and 52-week lowest stock price. The result of the multiple regression analysis which controlled for both company-specific and event-specific variables supported the anchoring heuristics. Conclusions: For stocks related to the Korean distribution industry in the KOSPI market, the anchoring heuristics theory provides a consistent explanation for stock returns after large-scale stock price fluctuations that initially appear to be random movements.

Objectives: The purpose of this study was to investigate the psychological characteristics of the Sasang constitutions by using Braverman nature assessment (BNA). Methods: One hundred seventy-four students participated in this study, and among them, the 142 individuals who had clearly identified Sasang constitutional types were used for the analysis. Sasang constitutions and the Braverman temperaments of the subjects were determined by using a questionnaire for the Sasang constitution classification (QSCC) II and BNA, respectively. Body mass index (BMI) was used to compare the inclinations of the Sasang constitutions and Braverman temperament types. Results: Significant differences in Braverman temperament type existed among the Sasang constitutions (P = 0.042), and the relations between Soyangin and the dopamine type and between Taeeumin and the gamma-aminobutyric acid (GABA) type were meaningful. Significant differences were also shown in the comparison with the Yin and the Yang constitutions (P = 0.017), and the post-hoc analysis showed a strong and significant relation between the Yang constitution and the dopamine type and between the Yin constitution and the GABA type. The one-way analysis of variance (ANOVA) and the independent t-test were conducted to examine the BMI and the degree of obesity among the Sasang constitutions and the Braverman temperament types. Concerning the BMI, Taeeumin showed a bigger BMI than the other constitutions (P < 0.001), but no significant differences in the BMI were observed between the Braverman temperament types. Conclusion: Soyangin has a close relationship to the dopamine type and Taeeumin has a close relationship to the GABA type. The correlation between two types were more clear when the Yin and the Yang types were compared to Braverman temperaments. These results may serve as a basis for identifying the psychological traits of Sasang constitutional types, especially in regard to the characteristics related to the four Braverman temperament types.

The purpose of this study was to survey the general characteristics, lifestyle include health habits, subjective health problems include physical, psychological and overall health complaints that occurring among Korean and Japanese nursing students. Data collected with the self-administered Okayama Medical Index Health Questionnaire(devised Cornell Medical Index) from 466 Korean and 688 Japanese Nursing Students were analyzed. The subjects were 18 to 24 years old in their 1st, 2nd, 3rd and 4th year-class of nursing department. The total O.M.I. score(section A-R) ranged from 1 to 110 with an average of 22.3(SD=11.5) in Korean nursing students and 18.3(SD=10.1) in Japanese nursing students. A statistically significant inverse correlation was observed between Korean nursing student and Japanese nursing students for the overall health complaints. Korean nursing students have more health problems than Japanese nursing students in terms of physical and overall health complaints excluding psychological problems. About $4\%$ of Korean nursing students were current smokers and $64.2\%$ of Korean nursing students were drinker. Korean nursing students in the drinker's group were more likely to eat fatty foods(p<.001), and take worst lifestyle and have more subjective health problems than non drinker's group of Korean nursing students. Korean nursing students were more likely to perform bad health behaviors than Japanese nursing students. The drink habit is one of the biggest problems among the nursing student, and then we have to have the mobilizing for 'Change on Alcohol' in our universities. This conclusion should provide grounds for future studies of strategies for health promotion and of prevention measures for psychological ill-health of nursing students.

This study was conducted to investigate the effects of watching a virtual reality (VR) forest video on stress reduction in adults. Experiments were performed in an artificial climate chamber where temperature, humidity and illumination were controlled. To cause stress in subjects, the subjects were asked to multiply two digit numbers by one digit numbers for two minutes. The subjects then watched a VR forest video for five minutes. During the experiment, the heart rate variability (HRV) and heart rate (HR) of subjects were continuously measured for evaluating their physiological state. After measuring the baseline and watching a VR forest video, their psychological state was evaluated using the profile of mood state (POMS), semantic differential (SD) method, and positive affect and negative affect schedule (PANAS). The results of physiological evaluation after watching a VR forest video showed a decrease in the stress index and HR, an increase in the activity of the parasympathetic nervous system, and the standard deviation of normal to normal RR intervals (SDNN). The results of psychological assessment confirmed that watching a VR forest video induced "comfort", "natural", and "soothed" feelings in subjects. In addition, watching a VR forest video decreased "tension-anxiety (T-A)", "depression-dejection (D)", "anger-hostility (A-H)", "fatigue (F)", "total mood disturbance (TMD)", and increased "vigor (V)" compared to the base line, and decreased "negative affect" and increased "positive affect." These results indicate that watching a VR forest video decreases adults' stress index, stabilizes physiological state, and has a positive impact on psychological state. The findings of this study can serve as a basis for providing forest welfare services to people in the blind spots of forest welfare, and can lay a foundation for the adoption of VR, one of the technologies of the fourth industrial revolution in forestry.
