The conflict management of forest recreation, especially conflict management between hikers and MTB users, has drawn much attention as one of major issues in forest policy making. The main purpose of this study was to investigate hikers' conflict perception against MTB users and their attitudes toward the necessity of conflict management actions, and to identify factors influencing those attitudes. The research data were collected through online surveys of 644 men and women hikers who are aged 20 or older and not participating in MTB riding. The major findings of this study can be summarized as follows: First, the levels of goal interference and social value conflicts against MTB users were not so high, but rather, the awareness level of compatibility was much higher than that of conflict, and hikers' awareness level of safety risks posed by MTB users was also considerably high. Second, hikers' attitudes toward the necessity of conflict management actions were generally shown to be considerably positive, but those attitudes toward indirect management actions such as information, education, and compliance with norms of conduct, were significantly positive than those attitudes toward direct management measures such as zoning, enforcement, and regulations. Finally, the results of the multiple regression analysis showed that four factors that most significantly affect hikers' attitudes toward direct or indirect conflict management actions are behavioral norms conflict, safety risk, compatibility and age. Safety risks had most important influence on hikers' attitudes toward the direct management actions, but behavioral norms conflicts had most important influence on indirect management actions.

Free cash flow is known as a typical type of agency conflict between managers and shareholders in a firm. The insurance industry, which is not growing, is particularly susceptible to such excessive cash flow. We herein investigate the effects of stock ownership plans on reducing agency conflicts. We adopt undistributed cash flow to proxy free cash flow, and size, default risk, group membership, leverage, investment opportunity, and stock options are selected as explanatory variables. We find that stock option plans are effective(at a 10% level) in reducing free cash flow.

In this study, the risk level of architectural works was calculated by applying work period and number of input workers based on accidents records from 2012 to 2014 and the architectural works were divided into four groups(High-High, High-Low, Low-High, Low-Low) according to risk levels of fatal accidents and loss time accidents. And then questionnaire on the job stress level of workers was performed for 670 workers working in the architectural work using Korean Occupational Stress Questionnaire Form developed by KOSHA. And then the relationship between the risk level and job stress level of four groups was analyzed. Results showed that 1) risk levels of fatal and loss time accidents applied by work period and input workers were analyzed to be different with those of previous research based on the number of fatal and loss time accidents; 2) job stress level of workers has been analyzed to have a significant relationship with the risk level of fatal and loss time accident; 3) specially, the average of job stress level of 'HH(High-High)' group was higher than those of other groups; 4) among the subfactors of job stress, interpersonal conflict, job insecurity, organizational system and lack of reward were analyzed to be key factors to affect the risk level.

이 연구는 국내의 여성교도관들의 다양한 스트레스 관련요인과 그 영향력을 분석하기 위한 경험적 연구이다. 가장 중요한 연구의 검증주제는 어떠한 직업과 가정의 갈등요인들이 여성교도관들의 스트레스에 미치는지 그리고 영향력은 어떠한지를 분석하고자 하였다. 더 나아가 일반적으로 교도관들의 스트레스와 관련되어 있다고 알려져 있는 개인적 단위의 요인들과 조직적 단위의 요인들의 영향력과 유의미성 역시 검증하였다. 이 연구의 분석을 위해서 국내의 12개의 교도소에서 근무하고 있는 여성교도관들 172명을 대상으로 설문조사를 수행하여 데이터를 수집하고 회귀분석을 실시하였다. 분석결과 여성교정공무원들의 스트레스에 영향을 미치는 요인들은 보안과 근무여부, 생활만족도, 상관의 조직운영에 대한 인식, 그리고 육아와 가사를 근무와 병행하는 어려움, 남성중심조직문화의 어려움의 5가지 변수들이었다. 주목할 만한 것은 보안과 근무여부, 생활만족도, 상관의 조직운영에 대한 인식 그리고 육아와 가사와 근무병행의 어려움의 네 가지 요인들은 모두 여성교도관들의 스트레스를 감소시키는 요인들이었다. 그러나 남성중심조직문화의 어려움은 여성교도관들의 스트레스를 증가시키는 요인인 것으로 나타났다. 여기서 육아와 가사와 근무병행의 어려움과 남성중심조직문화의 어려움은 여성교도관들의 직업-가정갈등요인으로 분석에 사용되었다. 이와 같은 결과는 여성교도관들이 남성들에 비해 특별히 다른 스트레스 요인을 가지고 있지는 않으며 심지어 육아와 가정생활과 관련된 업무의 부담까지도 스트레스 요인으로 인식되지 않고 있다는 점이다. 그러나 남성중심적인 업무환경은 여전히 여성교도관들의 스트레스를 증가시키는 가장 심각한 위험요인이라는 것이 발견되었다. 이와 같은 연구의 발견에 근거한 논의가 결과와 논의에서 해석되고 논의되었다.

The shrinkage preliminary test ridge regression estimators (SPTRRE) based on Wald (W), Likelihood Ratio (LR) and Lagrangian Multiplier (LM) tests for estimating the regression parameters of the multiple linear regression model with multivariate Student's t error distribution are considered in this paper. The quadratic biases and risks of the proposed estimators are compared under both null and alternative hypotheses. It is observed that there is conflict among the three estimators with respect to their risks because of certain inequalities that exist among the test statistics. In the neighborhood of the restriction, the SPTRRE based on LM test has the smallest risk followed by the estimators based on LR and W tests. However, the SPTRRE based on W test performs the best followed by the LR and LM based estimators when the parameters move away from the subspace of the restrictions. Some tables for the maximum and minimum guaranteed efficiency of the proposed estimators have been given, which allow us to determine the optimum level of significance corresponding to the optimum estimator among proposed estimators. It is evident that in the choice of the smallest significance level to yield the best estimator the SPTRRE based on Wald test dominates the other two estimators.

In analyzing the effect of the central place improvement projects, this study classifies subject residents into two groups of the residents of the project target regions and those of surrounding villages, and conducts verification. As a result of analysis, Variety of cultural programs is the only factor that positively affects the satisfaction level of the residents of the project target region, and it has been analyzed at the significance level of 10% that a one-unit increase in securing rest areas lowers the satisfaction level of the residents of surrounding villages. This shows that the effect of the central place improvement projects currently promoted is at a low level, and there is also a risk of conflict between the residents in the target region and those in surrounding villages. Although there is no statistical significance, analysis shows that a method to provide the residents in surrounding villages with the project-related information and to guarantee their participation in the project enhances the satisfaction level of the residents of surrounding villages. Therefore, institutional improvements reflecting this need to be made.

Biotechnology has reached the level of giving birth to new forms of life and with this is a growing controversy in the conflict between science and ethics. Especially, GMOs are closely linked to the food products we consume and thus, the majority of the public shows a very sensitive reaction to the safety of GMO food products. Many perspectives arose surrounding the issues of safety on the human body and the ecology. This outlines diverse structural mechanisms to be set up to ensure safety such as risk assessment, risk management etc. Despite the precautionary principle guaranteed in many ways, the problem arises whether and how this principle can be taken in the safety assessment. GMOs due to its uniqueness do not end with just the possession of the technology involved but must also be considered with the prerequisite that they could be cultured again. Therefore the reinforcement of safety assessment system is necessary. That is, the reinforcement of risk assessment including field tests, the consideration of socio-economic effects, the coordinated system of relevant authorities, the development of technology for safety assessment.

Objective : The purpose of this study was to investigate the association of depressive/anxiety symptoms with psychosocial factors including ego resilience, social conflict, and social support as well as hemoglobin A1c in patients with diabetes mellitus (DM). Methods : The subjects were 144 patients with DM. Depressive/anxiety symptoms were evaluated by the Hospital Anxiety and Depression Scale. Sociodemographic factors, hemoglobin A1c, ego resilience, social conflict, and social support were measured. Multiple regression analyses were performed to examine the impact of hemoglobin A1c, ego resilience, social conflict, and social support on depressive/anxiety symptoms. Results : A total of 32.6% and 24.3% of participants were identified with depressive and anxiety symptoms, respectively. Depressive/anxiety symptoms positively correlated with the social conflict score. Conversely, ego resilience and social support negatively correlated with depressive/anxiety symptoms. In the final model of the multiple regression analyses, ego resilience was associated with a lower level of depressive (β=-0.083, p=0.019)/anxiety (β=-0.125, p=0.001) symptoms whereas social conflict was related to a higher level of depressive (β=0.353, p=0.011)/anxiety (β=0.460, p=0.003) symptoms. Also, hemoglobin A1c positively associated with anxiety symptoms (β=0.495, p=0.012) whereas social support negatively related to depressive symptoms (β=-0.464, p=0.004). Conclusion : We found possible risk and protective psychosocial factors of underlying depressive/anxiety symptoms among patients with DM. Our findings suggest that enhancing ego resilience and social support as well as decreasing social conflict would be crucial in the prevention and management of depressive/anxiety symptoms in patients with DM.

This study was designed to identify the relationships of role-conflict and role-overload, coping strategies, and stress response of clerical workers. The subjects were 115 clerical workers from two company. The instruments were the role-conflict and role-overload scale developed by Lee(1989), coping scale developed by Latack(1986), and the stress response scale developed by Chang(1993). Analysis of data was done by descriptive statistics, Cronbach's $\alpha$, Pearson correlation coefficietnt, ANOVA. The results of this study were summarized as follows ; 1. The average score for the level of stress response was $83.6({\pm}9.1)$. The high risk stress group was 86.1% of the clerical workers, the latent stress group members was 13.9%, and healthy group was 0%. The overall stress level was very high. 2. Considering the coping strategies by sociodemographic factors, the use of control coping strategies showed significant differences by work-time. The use of symptom management coping strategies showed significant differences by sex, age, married status, year of career, pay, and type of work. The organizational coping strategies showed significant differences by year of education and type of work. 3. The clerical workers who had worked below 44 hours per week complained significantly lower stress response(F=4.942, p<.05). 4. Above 65% of all respondents answered that they needed all of organizational level coping strategies. 5. The role-confilct positively related to escape and organizational level coping strategies(r=.562, r=.495, p<.05). The role-overload didn't related to individual level coping strategies, but positively related to organizational level coping strategies(r=.320, p<.05). 6. The control coping strategies and the escape coping strategies positively related to symptom management, organizational level coping strategies(r=.409, r=.324, r=.316, r=.339, p<.05). 7. The relationship between role-related stress and stress response revealed positive correlation(r=.482, r=.431, p<.05), and the relationship between stress response and control, symptom management coping strategies revealed negative cor-relation(r=-.3204, r=-.3146, p<.05). In conclusion, this study revealed that relationship of role related stress, coping strategies, stress response was statistically significant. The result of this study support that coping strategies vary across situation of stress. Based on survey results, future studies should consider coping strategies in specific stress situation and concept of symptom management coping strategy. Also organizational or training interventions could be developed and initiate to help to increase the use of adaptive coping strategies in light of individual and situational differences.
