The aim of this study was to clarify how the role stress of administrative workers in medical institutions affects burnout, job satisfaction, and organizational commitment. The study conducted surveys on administrative workers at ten general hospitals with more than 200 beds for one month between July 13 and August 18, 2015. The surveys then underwent factor analysis, average variation extraction, a suitability index of the research model, and a path-coefficient estimation analysis of the research model using AMOS 18.0. The main results revealed a positive (+) effect according to the role conflict and role excess on burnout, and a negative (-) effect of burnout on job satisfaction, while they displayed no significant relationship with organizational commitment. These results suggest that clear guidelines and unity in instructions are needed to reduce the role of stress in cooperative tasks between departments and that optimizing the roles of organization members by accurately measuring and weighing tasks can increase the attachment to the organization and ultimately improve the individual job performance.

The purpose of this study was to examine the levels of sustainability of marine sport events by types of events and thus to provide fundamental information that helps developing sustainable marine sport events. In order to accomplish such the purpose, this study employed survey methodology with a total of 285 visitors to marine sport events. Questionnaires were developed based on Tripple Bottom Line theory suggested by previous research and validated throughout a panel of experts to check out content validity. Data collected were analyzed using descriptive statistics and ANOVA with Scheffe post hoc tests. Accordingly following findings were derived from current study. First, among 12 positive sustainability variables, marine space improvement had the highest mean score(M=3.82) but creation of jobs had the lowest mean score(M=3.46). Among 11 negative sustainability variables, traffic jab had the highest mean score(M=3.16) but conflict between participants and residents had the lowest mean score(M=2.73). Second, a festival typed marine sport event had the significantly high mean scores in all positive sustainability index including economic sustainability(M=3.79), social sustainability(M=3.84) and environmental sustainability(M=3.80). Third, a business typed marine sport event had the relatively higher mean scores in all negative sustainability index including economic sustainability(M=3.22), social sustainability(M=3.26) and environmental sustainability(M=3.25). In conclusion, these findings suggest that marine sport event organizers concentrate on marine sport event with more sustainability potentials.

The current study aimed to explore the suicidal behaviors and risk factors of completed suicides using psychological autopsy and use them as index variables to classify suicidal types. In addition, this study looked into the influential factors that affect each suicidal type. related to suicidal behaviors and suicidal risk factors by psychological autopsy. In addiction, the distinctions among the classes were analyzed. For this, psychological autopsies were conducted on the families and the close ones of 128 completed suicides. Then, the index variables were finally chosen for classifying suicidal types. The selected index variables for suicidal risk factors were mental disorders, suicide/self-harm, significant changes in physical appearance, marital conflict, adjustment and relationship issues at work/school, unemployment/layoff, jobless status and serious financial problems. The selected index variables for suicidal behaviors were expressing their suicidal attempts, writing suicidal notes, asking for help, the time/place/method of suicidal behavior, past suicidal/self-harm experience and the first person who witnessed the suicide. The Latent Class Analysis(LCA) and the 3-step method were used for classifying suicidal types. Then external variables(financial changes, cohabitation, existence of stressors, changes in stress level or relationships and family members with mental disorder/alchohol problems/ physical disorders, and work/school stisfaction) were applied for distinguishing classes. As a result, 5 classes(financial problems, adjustment problems, complex problems, psychiatric problems, and response to event[s]) were revealed on suicidal behaviors and 3 classes(residence- suicidal attempt- found by family, nonresidence- nonsuicidal attempt- found by acquaintances, residence- nonsuicidal attempt- found by family) were presented on suicidal risk factors. External variables such as gender, marital status, cohabitation, changes in relationships significantly differentiated among the 3 classes. Especially, class 3(residence- nonsuicidal attempt- found by family) tended to cohabit with others, were married, and had a significantly high level of interpersonal conflicts. When comparing the 5 classes of suicidal risk factors, auxiliary variables such as economic changes, cohabitation, stress, relationship changes, and family-related problems, and school/work satisfaction significantly differentiated the 5 classes. Especially class 3 (complex problems) experienced comparatively less family-related problems, but showed an aggravating level of personal stress. Suicial prevention strategies should be provided considering the characteristics of each class and the influential factors.

Objectives：This study was conducted to investigate the degree of psychopathologies of the family members of children with chronic convulsive disorder and evaluate the structures and dynamics of those families. Methods：The participant patients and family members were recruited from the population attending the outpatient clinic of department of pediatric neurology in Seoul National University Hospital in Korea. All the patients had idiopathic chronic convulsive disorder. Any patient with mental retardation, pervasive developmental disorder and gross brain pathology was excluded. As controls, normal students were chosen and their sex, age, achievement, socioeconomic status were matched to patients. The author interviewed the children and their family members twice and obtained informations about patient-parent relationship, patient-sibling relationship and others. For in-depth evaluation, we used family environment scales(FES), symptom Checklist-90-revised(SCL-90-R), self administered dependency questionnaire for mother(SADQ). Results：After interviewing with the parents of epileptic children, overprotection of parents, hostile feeling of siblings toward index children were higher than controls. The parental conflict was also more expressed than control families. According to results from FES, the scores of the subscales of expression, achievement-orientation, intelligence-orientation and active recreation were significantly lower than control group. The epileptic children showed higher dependency to parents especially in affection, communication and traveling areas of SADQ than control group. Maternal psychopathologies evaluated by SCL-90-R were much higher than the mothers of controls. According to T scores of SCL-90-R, about 40% of mothers with epileptic children had the risk of clinically significant depressive or anxiety disorders. Conclusion：These results suggested that the family members of epileptic children had more relationship problems and psychopathologies than control group and some mothers might have clinically significant depressive or anxiety disorders. so, effective psychiatric family interventions are needed for resolution of conflict and psychopathologies of family members.

This study, as a case where the environmental conflict and dispute arose between the use and the conservation as in the other protected areas in Korea, took the first step to build ecological citizenship to solve various and complicated issues in a fundamental level by providing a basic information on differentiated environmental perceptions of the locality and the visitors of Seoraksan National Park. The questionnaire survey was employed on September 6th and 7th with 150 residents of the park area and 200 visitors of Osaek-Daechungbong trail. Total number of 13 survey questions was introduced using Dunlap and Liere's NEP index. The result shows that the perception of 'balance of nature' was more dominant to the perception of 'humans over nature' and the perception to the 'limits to growth' was also somewhat positive in both groups. The differences in environmental perceptions between the groups exist; the visitor group tended to have more positive level of acceptance of NEP views. Such differences in perceptions suggest that a different normative approach should be taken to the residents of the national park with less pro-environment in their perceptions when policy making. It thus seemed possible that ecological citizenship could be realized since the younger and the higher education level are, the more pro-environment. The findings of the research may cause some concerns however, because the study has been confined as a case study with basic understanding of environmental perceptions and its differences between the interest groups. More extensive research is required to confirm if this is generalized.

Vestibulo-ocular reflex (VOR) is a compensatory response of the extraocular muscles generated by vestibular signals to stabilize images on the retina during head/body movements. It has been reported that mismatches between retinal and vestibular information, which cause motion sickness or cybersickness, modify VOR. To investigate the characteristic changes of VOR in subjects experiencing cybersickness, we developed a low-cost, multi-purpose VOR measurement system using LabVIEW and Arduino. To test the applicability of the system, we performed two experiments. In Experiment 1, horizontal and vertical VORs of four participants were measured using a vestibular autorotation task. In Experiment 2, eight participants were exposed to a virtual navigation to measure changes of VORs as an index of cybersickness. We observed significantly greater head rotations and eye movements while the participants were exposed to the virtual navigation than to a static image. The results suggest that the present system can help understand the psychophysiological mechanisms of cybersickness symptoms.

Conflicts between humans and wild boars (Sus scrofa) have increased because of causing crop damage and appearing in downtown. Management to reduce population size has mostly been implemented on pests, but knowledges about ecological values are very rare. Rubbing trees by wild boar was investigated to figure out characteristics and for management ecologically from July to October 2013 in a mixed forest, Geochang, Gyeongnam Province, Korea. Pinus rigida was most frequently founded, and rubbing trees, both conifers and deciduous, were mainly located in 200~600 m above sea level. DBH was no significant difference between rubbing and control trees. The use intensity of conifers was higher than that of deciduous. The coverage of foliage layers and the number of woody plants within a radius of 2.5 m of trees (rubbing and control) were also investigated and compared to determine ecological characteristics. There were 1,332 individuals founded from 25 families. In the coverage of foliage layers, the understory and midstory showed statistically significant, but not in the subover and overstory. The number of Shrubs and saplings are higher in rubbing trees than those of control, but no difference in stems. Total individuals, the number of species, species diversity index(H') within a radius 2.5 m is considerably higher in rubbing trees with high intensity than those of low intensity and control. Our results show that wild boar mainly selected and used conifers more frequently as rubbing trees. Wild boar also modified the physical environments around rubbing trees. Consequently, the positive effects such as species diversity is increase. Thus the conservation policies is required after the intensive population reduction every 3-4 years for forest ecological management rather than annual sustainable hunting.

The image of woman shown in an animation was pretty extraordinary as Disney has kept the conservative tendency so far. The two princesses in were described as independent women getting out of the traditional gender role and dependence on men. For this reason, there is a tendency that interprets as a feminist work. Even though the character showing the image of independent woman could be an essential index to define feminist work, it is not enough to define the tendency of works. Thus, this study reviewed if it would be valid to interpret as a feminist work. First, the 'sisterhood' which is the main theme of contained the feminist concept as 'women's solidarity' on top of friendship between sisters. Therefore, when analyzed focusing on the core concept of women's solidarity like difference, empathy, and solidarity, reflected 'differences' in narration, character, and image, etc. When differences in sisters which became the cause for misunderstanding and conflict were acknowledge based on their true love, the process of forming empathy and solidarity was described. The solidarity between Elsa and Anna not only became the power to defeat the enemy, but also reflected the feminist value of forming the community of coexistence like Adelen which was rebuilt after getting back the spring. Thus, it was verified that is a feminist work.

The main purpose of this study is to provide an objective evaluation standard for the assessment of marine spatial characteristics via Ulsan floating offshore wind power project using HEA.. Various levels of damage occur in the waters (5,017.6) near the floating offshore wind power terminals in Ulsan, including commercial damage, ecological destruction and reduction in quality of life due to seascape damage. Alternative restoration projects for calculating the economic value of damage were selected including artificial reef projects and estimates based on HEA. For basic households with a 4.5% social discount rate and a 100% maturity index over four years, the damage was approximately 457 hundred million won. The HEA in this study resolves the possible irrationality in the evaluation of marine spatial characteristics, since the value is calculated based on objective and clear DATA. Therefore, the study results are intended to facilitate conflict resolution between stakeholders in the future during the implementation of the marine spatial plan.
