Purpose: The purpose was to investigate the relations among job stress, depression, social support, and coping strategies of nurses. Method: The data were collected from 362 nurses. A self-administered questionnaire was used to assess general characteristics, job stress, depression, social support and coping strategies. Results: The prevalence of depression was 41.7%. Scores of job demand and insecurity, and organizational climate were very high. Logistic regressions showed that nurses, who were single, their 20s, had less than a career year, or working in private hospitals, associated with an increased risk of depression. The sub-scales of job stress except interpersonal conflict and lack of autonomy contributed to an increased risk of depression (lower group; OR=0.248, 95% CI:0.14-0.43). Also individual and organizational support and control coping strategies were associated with depression(lower group: OR=2.993, 95% CI: 2.11-6.30; OR=2.993, 95% CI: 1.51-5.65; OR=2.372, 95% CI=1.43-3.93). Conclusion: These findings indicated that the job stress, especially organizational climate, insecurity of job, lack of reward, individual and organizational support, and control coping strategies contributed to a risk of depression. In order to prevent the depression, the organizational support and strategies will be needed. The depression in specific context and organizational climate should be considered in future studies.

Purpose: This study intended to grasp real context of Cardiovascular disease (CVD)-related factors of Korean blue-collar workers, especially CVD-related knowledge, perception, beliefs, benefits and barriers of behaviors according to the health belief model. Methods: We interviewed twenty two workers working in two small-sized companies and performed two series of focus group interviews. Data were analyzed by deductive content analysis approach based on Elo & $Kyng{\ddot{a}}s$. Results: Excepting participants who have CVD risk factors, most participants had lower level of CVD risk perception. The level of CVD knowledge was low but there was difference by gender. CVD-related beliefs were 'fatal disease', 'caused by lifestyle' and 'difficult to prevent by themselves'. The risk reduction behaviors were motivated by current or family history of hypertension. But there were barriers to interfere practice of preventive behaviors such as poor quality of food provided by cafeteria in the workplace, frequent overtime, victim mentality as one of vulnerable social group, housework and financial burden, lack of facilities for rest and physical activity in the workplace. Conclusion: To develop intervention for reducing CVD risks in Korean blue-collar workers, we need to focus on improving CVD knowledge and perception and modifying work-related environments such as low quality of food and lack of facilities for rest and physical activity in the workplace.

Context: In the last half century, discovering, developing and introducing of clinical agents from marine sources have seen great successes, with examples including the anti-cancer compound trabectedin. However, with increasing need for new anticancer drugs, further exploration for novel compounds from marine organism sources is strongly justified. Objective: The major aim of this study was to evaluate the antitumor and antioxidant potential of Sargassum tenerrimum J.Agardh (Sargassaceae) on Ehrlich ascites carcinoma (EAC) in Swiss albino mice. Materials and Methods: An ethanol extract of S. tenerrimum (EEST) from whole algae was used to evaluate cytotoxicity followed by in vivo assessment of toxicity, using biochemical parameters including hepatic and non-hepatic enzymes. Antioxidant properties were examined in animals bearing EAC treated with daily oral administration of 100-300 mg/kg extract suspension. Results: Antitumor effects of EEST in EAC bearing mice was observed with LD50 1815 mg/kg. Parameters like body weight, tumor volume, packed cell volume, tumor cell count, mean survival time and increase in life span in animals in the EAC bearing animals treated with EEST 300 mg/kg was comparable with control group. Significant differences were also seen with changes in total protein content, hepatic enzymes contents, MDA level, and free radical scavenging enzymes in untreated vs. EEST treated group animals. Conclusions: Evaluation of antioxidant enzymes and hepatic enzymes in the EAC animal model treated with EEST exhibited similar effects as the positive control drug 5-flurouracil. S. tenerrimum extracts contain effective antioxidants with significant antitumor activity.

There are multiple process mechanism in causal reasoning, which is estimation of the causal strength between cause and result. Further, because these mechanisms operate on different time phase during causal reasoning, it is highly possible that different individual difference factors are related to individual mechanisms of causal reasoning. Especially, the phenomena of conditionalization and discounting reflect attention to multiple potential causes when people infer the relationship between cause and effect. In this study, we manipulated self-construal which is an individual difference factor that reflects context sensitivity in cognition. As results, no difference was observed in conditionalization between individuals with an independent self-construal and those with an interdependent self-construal. However, independent self-construal group was observed to be lower in discounting than the interdependent self-construal group. The results indicate that conditionalization and discounting are independent cognitive process in human causal reasoning.

The three cities, Yeosu, Suncheon, and Gwangyang, in located in Gwangyang Bay which functions as a representative coastal industrial area in Korea, form a single functional area of living, municipality, and economy. In this regional context, some local merchants and scholars are promoting a inter-municipal cooperation of three cities. This study analyzes how the group of specialists perceives and evaluates the inter-municipal cooperation of three cities. The group of specialists highly evaluate the potential of future development of Gwangyang Bay region, and the relevance and necessity of feasibility of inter-municipal cooperation of three cities. It is estimated that the inter-municipal cooperation of three cities would need 8.3 years for its full-fledged shape. In order to accomplish the inter-municipal cooperation, the sharing the development vision of Gwangyang Bay region and the understanding and consent of the residents for the inter-municipal cooperation are suggested as the most important factors.

The purposee of this study was to identify the effect of perceiver's clothing attitude on male impressions created by the clothing cues and contexts. In addition, the effect of perceiver's evaluations of clothing appropriateness on male impressions. The subjects consisted of 256 male undergraduate students and 256 middle aged men. The experimental materials developed for this study were a set of stimuli and response scales. The stimuli were 8 color Photographs of drawings of a male figure in clothing which were minipulated in two levels, each of three clothing cues including type, style and color. The experimental design was full factorial design of 2(contexts$\times$clothing types$\times$clothing style$\times$clothing color). Each of the 16 sub-samples includes 16 subjects from the two perceiver group. Questionnaires used to measure perceivers responses to the stimuli were 7-point semantic differential scales composed of 37 bipolar adjectives representing personal traits. Four aspects of clothing attitude(fashion interest, status symbols consiousness, clothing conformity, practicality & comfort)were used to classify subjects into groups of 20 five-point likers type questionnaires adapted from the previous research. Clothing appropriateness were developed 5 point likest scales for evaluation of a stimulus person in each context. The data was processed by factor analysis, ANOVA, multiple classification analysis, Duncan's multiple range test, cluster analysis, MANOVA and pearson's product moment correlations. The major findings drawn from this study were as follows: 1. Perceiver's clothing attitude influenced impression formed by the social contexts and clothing crises. In three groups classified by their clothing attitude, the status symbol-oriented group was most affected by the social contexts and clothing cues. 2. Perceiver's evaluation of clothing appropriateness was related with impressions by a stimulus person. In summary the effect of contexts and clothing cues on impression formation varied according to perceiver's clothing attitude and clothing approopiateness.

In this study, elementary school students' science learning characteristics together with the levels of inquiry requirement in elementary school science experiment instruction were investigated in terms of the affective domain. We divided seventy-three students of the fifth ade into two groups according to the levels of inquiry requirement. After each instruction had been implemented, the characteristics of the students' learning in terms of the affective domain were compared and analyzed within the context of the levels of inquiry requirement. There were no significant differences between Level 1(LL) and Level 2(HL) groups in terms of the affective characteristics. These results may be caused by the burden imposed by the difficulty in thinking through and setting up the experimental methods. However, the HL group students' levels of interest in science experiments was higher than that of the LL group. In conclusion, the HL instruction contributed little to the improvement of affective characteristics. Some possible reasons might be that students felt difficulties with the somewhat unfamiliar instructions which required them to design and perform experiments. Higher levels of interest in science experiments amongst HL students' implies that well-organized and continuous exercises involving the design and performance of experiments could improve students' scientific affective characteristics.

Purpose: This study aimed to describe Korean nursing home nurses' perceptions on dysphagia management and their working experiences of older adults with dysphagia. Methods: Using a purposive sampling design, 23 eligible nurses were interviewed as four focus groups from 4 facilities out of nursing homes. The qualitative data from focus group interviews were analyzed using thematic analysis to classify common themes into larger categories. Results: Two main themes on the attributes of caring nursing home residents with dysphagia were 'Need for nursing resources' and 'Need for support'. In addition, four subthemes emerged as a result of analysis: 'need for nursing protocols for assessing and managing dysphagia', 'need for emergency care skills of nurses and nurse assistants', 'need for prompt and accurate management by cooperation of physicians and therapists', and 'need for partnership upon comprehension of visiting family members concerning dysphagia'. Conclusion: Nursing home nurses fully recognized the importance of dysphagia management; however, they experienced substantial barriers due to lack of adequate nursing protocols or partnership with family caregivers, insufficient training for emergency care, and deficient support from medical staff. Development of nursing guidelines tailored to the nursing home context and based on partnership among medical experts and family caregivers is needed.

The purpose of this study is to compare students' perception shaped by two different university classrooms: Traditional Classroom and ALC(Active learning classroom). We conducted survey of 71 university students who were taught by an identical instructor using same pedagogy. The survey questionnaires asked respondents about their perceptions on teaching and learning and physical environments relations, teaching proficiency, social context, student satisfaction and immersion. The data was analyzed using Student's T-test. The results showed that ALC group, compared to the traditional classroom group, demonstrated statistically higher awareness on teaching and learning and physical environments relations, teaching proficiency, and instructor-student unofficial relations. Based on these findings, implications and limitations of this study were discussed.

Purpose: The purpose of this study was to describe the role experiences of occupational health nurse. The research question was "what are daily experiences in practice?" Methods: The data were collected through the focus-group interviews with nine occupational health nurses and analyzed by the grounded theory of Strauss and Corbin (1998). Results: The core category on occupational health nurse role experience was named as "struggling alone with the dual role". The causal conditions included 'unfamiliar area' and 'new work'. The contextual conditions included 'overload of work, 'tasks beyond OHN job' and 'disharmony with colleagues'. The intervening conditions were analyzed as supportive factors and discouraging factors. There were action/interaction strategies 'getting information about tasks', 'working as a professional', 'establishing a cooperative relationship', 'seeking help' by trying to regulate the phenomenon. Finally they succeed in 'establishing the identity' and 'feeling proud', but sometimes they could be 'suffering from low morale', or 'considering turnover'. Conclusion: Through these results, it can be explained that occupational health nurses have been exerting themselves to establish their role with various situation through the conflicted context. Based on the findings, we suggest developing the diverse continuing education programs to be tailored for OHN's needs and reinforcing the occupational health services under the legal and political support.
