In South Korea, the conflict between development and conservation policy still exist among government ministries, and conventional development plan often has priority over conservation policy. Establishment of sustainable development and comprehensive management policy employing the results of ecosystem service studies are highly warranted, but researchers in South Korea are still limited and often misuse the concept of ecosystem services. Thus, we aimed to introduce the concept of Ecosystem Service (ES) and related terminologies such as Social-Ecological Systems (SESs), ecosystem function, trade-off, and human well-being in this paper. Additionally, this article reviewed and arranged key approaches in ES studies as follows: 1) field works, 2) mapping ecosystem services, 3) valuing ES, 4) quantifying trade-offs between ES and 5) understanding SESs. Based on those results, we suggest that field works for basic information have the first priority to be conducted among ES studies. Once basic information is sufficiently accumulated, researchers can perform applied ES research with accuracy. Finally, results of ES studies conducted by five approaches allow decision makers to consider both natural system and society simultaneously, and hence the results can be utilized for sustainable development and conservation policy based on ecosystem-based management.

The purpose of this work is to analyze the factors, criteria and importance that shippers in the international logistics industry take into account in choosing third-party logistics, and thereby to propose the directions of the areas and functions that third-party logistics will need to enhance on the basis of Analytic Hierarchy Process (AHP) methodology. To do that, this work collected and analyzed materials about changing environments of logistic industry and previous studies, and especially conducted a questionnaire survey on the factors to choose third-party logistics with the study subjects of shippers in the international logistics industry. To draw attribute factors, this work repeatedly chose and classified candidate factors through Delphi technique on the basis of the data of previous studies. The analysis results are presented as follows: regarding pairwise comparison between logistic cost and logistic service in relation of conflict, logistic service was recognized to be more important than logistic cost; regarding pairwise comparison between corporate capability and logistic cost, logistic cost was recognized to be more important; and regarding comprehensive evaluation, logistic service factors, including accuracy of order handling, service reliability, freight damage and compensation, a degree of fulfillment of promise, quality of transportation, and problem-solving ability, were found to be in high position.

Purpose: The purpose of this study was to investigate the relationships between psychosocial working conditions and psychological well-being depending on the gender among Korean interactive service workers. Methods: This study was a secondary analysis of the data extracted from the 2011 Korean Working Conditions Survey. For the present analysis, 15,669 workers who interact with others at work were selected. Based on the existing literature, a set of variables was chosen from the KWCS. Psychological well-being was measured using the WHO-5 well-being index. Results: The prevalence of poor psychological well-being was significantly higher among men (43.1%) than women (39.6%). Women were more likely to be exposed to demands for hiding emotions, bullying, and discrimination, whereas men were more likely to be exposed to psychological job demands, cognitive demands, demands for responsibility, role conflict and long working hours. Most factors were associated with poor well-being among women and men except demands for hiding emotions, skill discretion and development, physical violence, and sexual harassment. Conclusion: Based on these results, some practical suggestions are offered to help interactive service workers adjust to their duties.

Since the Millennium Ecosystem Assessment Report was published in 2005, the conflict between development and the preservation of the ecological environment has turned to paying attention to value assessments in rational decision-making. In recent years, the concept of ecosystem services has been recognized as a viable one for making significant decisions. However, a trade-off between increase and decrease occurs between the ecosystem services sub-categories (cultural service, regulating service, supporting service, and provisioning service), for which research centering on target sites is needed. To this end, the present study aims to investigate the trade-off relationship between service categories to search for reasonable decision-making strategies. As the research method, a survey was conducted using the translated version of SoIVES(Social Value for Ecosystem Services) 3.0 questionnaire of the United States Geological Survey. The research findings demonstrate the economic value, based on the derived monetary value of each service category, the economic value of the target site was compared among landscape aesthetic value 8,050,000 won, recreation value 6,750,000 won, biodiversity value 4,610,000 won, healing value 3,970,000 won, life-sustaining value 2,090,000 won, and productive value 220,000 won. And then the primarily recognized value criteria of the Tancheon ecosystem services illustrate landscape aesthetic and recreation value. Besides, this study illustrates visualized trade-off relationships based on user perception, and the derived relations illustrate the trade-off relationship between the cultural service, regulating service, supporting service, and provisioning service, as well as relationships between the components of the sub-categories.

Purpose: This study was conducted to identify the factors affecting container terminal worker's recovery experience from job stress. Methods: The subjects were 299 workers from one S dock in P city. Data were collected from April 5 to June 5, 2015 and analyzed by SPSS/WIN 18.0 program using descriptive statistics, t-test, ANOVA, $Sheff{\acute{e}}$ test, Pearson's correlation coefficients, and logistic regression. Results: The mean scores of job stress, ego-resilience, and recovery experience from job stress were 47.18, 46.90, and 49.17 respectively. Recovery experience according to the general characteristics showed significant correlation between daily exercise. There was a significant negative correlation between recovery experience and job stress, and a positive correlation between recovery experience and ego-resilience. Recovery experience was 2.54 times higher for a high ego-resilience group than for a low ego-resilience group, and the group that exercised was 2.25 times higher, than the non-exercising group. The group with a low level of interpersonal conflict was 1.97 times higher, than a group with a high level of interpersonal conflict. Conclusion: Based on this study, intervention programs to increase ego-resilience, decrease interpersonal conflict, and encourage over 30-minute-daily exercise for in container terminal workers should be developed to improve recovery experience of job stress.

This study analysed marital comflicts, related factors, and adjustments to those conflicts described by urban Korean women. The purpose was to discover directions for resolution that would enhance the helpfulness of volunteers or prfessionals working with women in counselling settings. The investigator interviewed 20 married women, all mothers and housewives living in Seoul, attending marriage encounter programs and the Lifeline telephone counselling service. An interview schedule using six open-ended questiona guided the data colleciton which took place between May 31 and December 29, 1988. Content analysis of the data revealed, in order of reported frequency, the following areas of conflict: relationships between husband wife, relationships with children, relationships between the wife and her mother-in-Law, unsatisfied sexual needs, the husband's extra marital relationships, lack of self actualization and finacial matters. Analysis of the data suggested the following factors were related to the conflicts: reasons for marriage, traditional views about marriage and divorce including to accept a marriage arranged by the parents, the husband's traditonal attitude toward the sex role of the wife, the husband's patriarchical authoritarianism, and his attitude toward the wife;s empolyment outside the home. The women thought these conflicts severely affected their relationships within the famaily, particularly with their children. Literature suggests links with such poor parent-child-family relationships and adolescent or young people's social problems. Volunteers or professionals working with married women in counselling situation need to be conscious of the possibility of these conflict during assessment, and direct their guidance toward such conflict resolution. The researcher makes several suggestions which include the need for the husband to give emotional supports to his wife, to recognize the worth of housework, to share the work of the home, to fine ways to enhance the wife's self-actualization and to ease dreary housework routines by prviding modern appliances.

This study describes an improved model for estimating pedestrian LOS (Level of Service) by utilizing the space occupied by pedestrians. The method introduced the concept of conflict along the bi-directional pedestrian flow which enables calculating conflict area and average travel time in walking. Especially, the method incorporates the idea of generalized density concept which can consider effective walking area and pedestrian flow rates that might vary during the analysis period. After establishing methodology, adjustments of pedestrian LOS criteria in term of walking space occupied by pedestrians were performed. As a result, walking-occupied space at capacity level is 0.68 and corresponding pedestrian flow rate was calculated as 80 persons/min/m, while different pedestrian-occupied spaces were ordered to classify LOS at the points where the gradient changes. Furthermore, the statistical verification of service levels has shown that there is significant difference among all LOS categories at 5% significance level.
