  • Ocean general circulation model developed by GFDL on the basis of MOM4 of FMS are examined and evaluated in order to elucidate the global ocean status. The model employs a tripolar grid system to resolve the Arctic Ocean without polar filtering. The meridional resolution gradually increases from $1/3^{\circ}$ at the equator to $1^{\circ}$ at $30^{\circ}N(S)$. Other horizontal grids have the constant $1^{\circ}$ and vertical grids with 50 levels. The ocean is also coupled to the GFDL sea ice model. It considers tidal effects along with fresh water and chlorophyll concentration. This model is integrated for a 100 year duration with 96 cpu forced by German OMIP and CORE dataset. Levitus, WOA01 climatology, serial CTD observations, WOCE and Argo data are all used for model validation. General features of the world ocean circulation are well simulated except for the western boundary and coastal region where strong advection or fresh water flux are dominant. However, we can find that information concerning chlorophyll and sea ice, newly applied to MOM4 as surface boundary condition, can be used to reduce a model bias near the equatorial and North Pacific ocean.

  • This study analyzed the relationships among perceptions of uncertainty, environmental characteristics and strategy maker\`s actual decision such as resource allocation in different organizational subunits by focusing on the hotel general managers in two different countries Korea and Japan. The results show that managerial perceptions of the environment would vary across organizations within an industry but it was surprising to fad that managerial perceptions did not vary more substantially across countries. General managers in both countries perceived government regulator\`s actions to be the most uncertain environmental factor. Hotels in Japan were more geared toward external effectiveness than were hotels in Korea. The findings of this study also suggest that when the organization faces high environmental uncertainty, it places greater emphasis on extemally oriented functions such as market research and product development.

  • This study was conducted to compare the contents of preservatives and general composition on four different types of cheese to provide useful data and information to the consumer. We analyzed preservatives (sorbic acid, benzoic acid, dehydroacetic acid, methyl p-hydroxy benzoate, ethyl p-hydroxy benzoate, propionic acid) and general composition (moisture, protein, fat) from total 102 cheeses which are 46 sliced cheeses, 22 string cheeses, 20 cream cheeses and 14 pizza cheeses. Preservatives were detected from total 14 samples, which are suitable for the authorized limits in Korea. Sorbic acid was detected from 13 samples (197.3~1,736.1 mg/kg) and propionic acid was detected from 1 sample (362.7 mg/kg). Considering from each type of cheese, cream cheese showed the high detection rate (60%); 12 samples of cream cheese contained sorbic acid. The moisture, protein and fat contents of cheeses were in the ranges of 44.3~56.8%, 7.2~24.6% and 19.6~26.8%. Cream cheese had the highest level of moisture (56.8%) and fat (26.8%), but protein level is very low (7.2%).

  • This study is based on grounded theory methodology by Strauss & Corbin(1998). Ten hospitalized subjects were interviewed for data collection. In the process of data analysis, 'acceptance' is found to be the causal condition, while 'health professionals' skillfulness', 'ward environment', 'history of hospitalization', and 'general conditions' were identified as context, 'felling of relief' as the core phenomenon, 'self-efficacy', 'support of others', and 'life style' as the intermediate situation, 'passive reaction', 'alternative reaction' and 'active reaction' as the strategy and 'stabilization', 'satisfaction', 'hope' and 'carrying out' as consequences. 'Feeling of relief' is found to go through the three stages of recognition-generation-maintenance after the five different patterns. 1) In case the health professionals are skillful, the ward environment is favorable, the general conditions of the patients improved and as a result the feeling of relief is strong, during the first hospitalization, the self-efficacy of the subjects tends to be strong. They proceed toward the goal set for themselves with a renewed hope and active or alternative reaction toward the feeling of relief. 2) The subjects tend to proceed toward the goal set for themselves with a renewed hope and active and alternative reaction toward the feeling of relief in case health professionals are skillful, the ward environment is favorable the general conditions of the subjects improved, self-efficacy is strong, and lifestyle is autonomous, during the second hospitalization even though support of others is merely superficial. 3) The subjects tend to stabilize, and satisfy themselves with the given situation with passive and alternative reaction to the feeling of relief in case health professionals are skillful and the ward environment is favorable but the general conditions worsened and accordingly the feeling of relief, is weak and life style is dependent during the second hospitalization although the subjects' self-efficacy is strong and support of others is specific. 4) The subjects tend to stabilize and satisfy themselves with the given situation with passive and alternative reaction to the feeling of relief in case health professionals are unskillful the ward environment is unfavorable, the general conditions improved, support of others is specific but life style is dependent and self-efficacy is weak during the first hospitalization. 5) The subjects tend to stabilize and satisfy themselves with the given situation in case health professionals are unskillful the ward environment is unfavorable but the general conditions improved support of others is specific and as a result self-efficacy is strong but life style is dependent.

  • Purpose: This study aimed to compare work-related musculoskeletal symptoms, occupational stress and nursing work environments of nurses working in patient-sitter wards and general wards. Methods: The study surveyed 240 nurses with more than one year of experience working in both patient-sitter wards and general wards. The collected data then was analyzed by SPSS statistics version 22. Results: As for the musculoskeletal symptoms, the survey showed that 85.2% and 67.8% of the nurses had such symptoms respectively in patient-sitter wards and general wards. In terms of occupational stress, no significant difference was observed between the patient-sitter ward and the general ward (t=-0.23, p=.821). Lastly, the study showed that there is a significant difference in terms of work environment considering the scores recorded 2.65 and 2.55 points respectively in patient-sitter ward and general ward (t=2.53, p=.012). Conclusion: Follow-up research should look at ways to lower the rate of experiencing work-related musculoskeletal symptoms; analyze work performances and establish work standards to lower occupational stress; and devise measures to improve the work environment for the nurses working in patient-sitter wards.

  • Purpose: This study was conducted to compare the characteristics of organizational structure and occupational satisfaction among nurses in general hospital and small to medium-sized hospital and to investigate the affecting factors on their occupational satisfaction. Methods: The study was based on the cross-sectional descriptive survey. A self-report questionnaire was used to collect data from 343 nurses between June and July, 2010. Data were analyzed by ${\chi}^2$-test, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and multiple regression using the SPSS/WIN 14.0 program. Results: Hierarchical structure was dominant in general hospital whereas relationship was highly valued in small to medium-sized hospital. Occupational satisfaction was positively correlated with work environment built on relationship, innovation and tasks. Factors significantly influencing on occupational satisfaction in general hospital included innovative work environment, nurses' income and their health status ($R^2$=40.3%). For the small to medium-sized hospital, they included innovative work environment, satisfaction in life, tasks and professionalism ($R^2$=40.4%). Conclusion: Organizational structure, especially innovative work environment and relationship-oriented attitude had a significant influence on nurses' occupational satisfaction. Therefore, nursing administrators have to develop and consider organizational structure to improve occupational satisfaction.

  • The aims of this study are to analysis about the contents associated with the ocean environment compared 17 special-subject textbooks to 2 common-subject textbooks, and to make some proposals for construction of contents. The results of it are as follows; 1. Only 17 books among 36 textbooks taught by the fisheries and marine high schools are contained to some contents related with ocean environment. The contents associated with the ocean environment take possession of 90%, 62% each of total pages in the textbooks, 'ocean pollution' and 'ocean environment'. 2. Of compulsory texts, namely, 'general fisheries', 'general ocean' and 'information treatment of fisheries-marine', the former 2 books are composed of 4.5%, 36.2% each relating with ocean environment. But the last one is nothing. 3. Therefore, even a little contents of ocean environment and its conservation, it is necessary to add as the reasonable rate to the characteristics of each book in 36 special-subject textbooks. 4. And also it is shown that the common-subject textbooks,'ocean science', ' earth science I' and 'earth science II', are composed of 35.7%, 10%, 16.7% each. So we'd like to recommend that the contents of ocean pollution and environmental conservation have to add more.
