This study examined individual characteristic factors and environmental factors as determinants of entrepreneurial intentions. As for individual characteristic factors, individuals' career orientations and entrepreneurial self-efficacy were examined. As for environmental factors, social supports and successful role models, labeled as personal environmental factors, were examined, and social perceptions for entrepreneurs, labeled as social environmental factors were also examined. Data were collected from undergraduates of business department, and graduates of the same department. The samples of 208 and 81 for each group were used for final analysis. Results showed that as a whole, career orientations affected entrepreneurial intentions. Specifically, entrepreneurial orientations had positive effects. and security orientations had marginally negative effects on entrepreneurial intentions, while, unexpectedly, autonomy orientations had no significant effects. Entrepreneurial self-efficacy had the strongest positive effects on entrepreneurial intentions. Social supports and successful role models, which were not identified as distinct variables by the respondents, were integrated as a new variable of 'network environments' for analysis in this study. Network environments positively affected on entrepreneurial intentions. Social perceptions for entrepreneurs, however, did not affect on entrepreneurial intentions. Based on the results of career orientations, self-efficacy, and network environment, the implications for activating entrepreneurship were discussed.

This study aimed to clarify any factors that may have effect on the appropriateness of hospital admission and hospitalization with the intention of facilitating more efficient occupancy of hospital beds and better medical services in the aspect of their quality, minimizing unnecessary occupancy of beds, and ultimately helping patients requiring acute treatments to use immediately hospitals. This paper selected 154 Stroke patients who left neurology department of one general hospital from March, 1, 2006 to September, 31, 2010 as targets to meet the rate according to medical care security and to see the trend of recent 4 years. As study method, this paper analized medical treatment record with AEP to evaluate the appropriateness of hospital admission and stay and the collected data was computerized through SPSS 12.0. Based upon the results above, the conclusion was drawn that the higher appropriateness of hospital admission and the shorter length of hospital stay will lead to the higher appropriateness of hospitalization. In other words, it is required to provide hospitalized patients with all kinds of behaviors including medical treatments and nursing care service, management of pharmaceuticals, tests, rehabilitation and symptoms, as well as instructions and information for patients. Meanwhile, as it was found that the length of hospital stay may affect the appropriateness of hospitalization, the longer length of hospital stay may result in reduced bed turnover rate. In this light, it is necessary to organize a task force team responsible for evaluation and control of the appropriateness of hospitalization and hospital stay length to improve the quality of medical service in a medical center, so that patients can leave the center timely. Ultimately, governmental supports such as expansion of long-term care facilities will reduce the necessary length of hospital stay so that patients with stroke can receive rehabilitative treatments and long-term care service shortly after completion of acute treatments.

Recently many treatment strategies have been developed to prevent suicidal ideation as it is increasing. Various community facilities and university centers are carrying out research to develop efficient treatment programs. This study examined how music can be used therapeutically for a case who is going through severe suicidal ideation. Various music therapy techniques are utilized including song psychotherapy, music and imagery and role play instrumental improvisation. A woman with severe depression for seven one-hour session. Both quantitative and qualitative data were collected to examine the changes in the suicidal ideation. As results, there were lots of changes in the client's attitude towards life through exploring inner world. Much of stability and sense of security were gained and emotional hardship was resolved in the process of therapy. The client was able to structure future plans productively as the suicidal ideation was reduced. In the process of role play instrumental improvisation, music allowed her to express issues regarding relationships with others, attitudes and in other areas as well. Music was used "as therapy" and solved many repressed emotions related to the trauma including psychological inhibition, tension, helplessness, lack of energy. Further music was able to bring the "false" ego with "true ego". The study implies that various psychotherapeutic interventions can alleviate depression and reduce suicidal ideation.

In this paper, we propose practical results for cache replacement policy by measuring cache hit and search time for each replacement algorithm through cache simulation. Thus, the structure of each cache memory and the four types of alternative policies of FIFO, LFU, LRU and Random were implemented in software to analyze the characteristics of each technique. The paper experiment showed that the LRU algorithm showed hit rate and search time of 36.044% and 577.936ns in uniform distribution, 45.636% and 504.692ns in deflection distribution, while the FIFO algorithm showed similar performance to the LRU algorithm at 36.078% and 554.772ns in even distribution and 45.662% and 489.574ns in bias distribution. Then LFU followed, Random algorithm was measured at 30.042% and 622.866ns at even distribution, 36.36% at deflection distribution and 553.878ns at lowest performance. The LRU replacement method commonly used in cache memory has the complexity of implementation, but it is the most efficient alternative to conventional alternative algorithms, indicating that it is a reasonable alternative method considering the reference information of data.

Purpose: This study was conducted to evaluate the factors influencing inadequate energy intake among Korean elderly. Methods: Our study included 1,869 elderly people (over 60 years old) who completed a dietary survey from the fifth Korean NHANES (2010). Factors that could affect the nutritional status of the elderly included age, family status, socio-economic factors (education, family income, livelihood security, employment), and health related factors (having chronic disease, functional status, diet therapy, depression, and suicidal thoughts). Energy and protein intake were assessed using the dietary intake data from 24hr recall method. Results: The percentage of people who consumed energy less than 75% of EEA for Koreans was 23.7% in men, 31.1% in women. The carbohydrate contribution to the total energy intake in the inadequate energy intake group was significantly higher than that in the adequate intake group (p < 0.05). Factors significantly related to inadequate energy intake after adjusting for age, family status, education, family income, employment, functional status, and suicidal thoughts were education (OR: 1.480 in men, 1.614 in women) and employment (OR: 1.751 in men, 1.464 in women), age 70 years or older in men (OR: 1.475), and living with family but without spouse in women (OR: 1.496). Conclusion: In summary, the results imply that energy intake of elderly would be affected by the status of social environment with aging and nutrition-related policy for Korean elderly should be based on the social status as well as health related conditions.

Rice is not only main food but also key farm income source of Korean farmers. In spite of the above facts, rice productivity was decreased on account of drought in every 2 or 3 years interval owing to the vulnerability of irrigation facilities throughout Korea in the past decades. As an context of the first five year economic development plan, all weather farming programme including 4 big river basin comprehensive development projects and large and medium sized irrigation water development projects were carried out successfully. Therefore the area of irrigated paddy were increased from 58% in 1970 to 76.2% in 1999. In the past decades, the Government had invested heavy financial funds to develop irrigation water but as an factor share analysis, the contribution rates of irrigation water and investment for farmland base development project have not been identified yet in national agricultural economic level. It is very scarce to find out the papers concerned to macro-economic factor share analysis or contribution rates of water and investment cost to rice production value in Korea considering the production function of the quantity of irrigation water and investment cost as independent variables. Accordingly this paper covered and aimed at identifying (1) derivation of rice production function with the time serial data from 1965 to 1999 and the contribution rates of irrigation water and total investment cost for farmland base development project. The analytical model of the contribution rates was adapted the famous Cobb-Douglass production function. According to the model analysis, the contribution rate of irrigation water to rice production in Korea was shown 37.8% which was equivalent to 0.28 of the production elasticity of water. The contribution rate of farmland base development project cost was revealed 22% and direct production cost of rice was contributed 60% in the growth of rice production and farm mechanization costs contributed to 18% of it respectively. The two contribution rates comparing with the direct production cost were small but without irrigation water and farmland base development, application of high-pay off inputs and farm mechanization might be impossible. Considering the food security and to cope with the frequent drought, rice farming and investment for the irrigation water development should be continued even in WTO system.

This study analysed general characteristic of Physical Therapists and congnition, participation, education, problems and requireanents for CBR. The objects of this study were 37 therapists who work at 27 of 39 PHC in Kyoungki province and data was collected for 20days from Jan. 12 to 31. 1998 and the results computed from 32 responses. First, Female therapists outnumber males. The age category 30 to 35 old represneted $56.2\%$ of the total number studied. $59.4\%$ of therapists had worked more than 7 years and therapists usually$(46.9\%)$ worked from 6 month to 2 years at the PHC. Junior college graduates were $84.4\%$, and respondents with family responsibilirt were $65.6\%$. Second, Recently pain control has become the major requirment of patiants at PH$(53.1\%)$. If they offered expaneded services - a rehabilitation program $(53.1\%)$, home vistation $(31.3\%)$. when asked about a working guide book, nobody had one. Third, $68.7\%$ of therapists were aware of the present level of CBR, $40.9\%$ of them had gotten an information from educated colleagues, and $68.7\%$ of therapists were aware of the present level of CBR, $86.4\%$ of therapists felt responsible to provide rehabilitation Fourth, For CBR, $93.7\%$ had positive ideas in which they could participate. $73.3\%$ wished to composed a team of various rehabilitational specialists. $73.3\%$ wished for the meeting day to be flexible and $86.6\%$ desired to meet once or twice a week. Fifth, Almost all$(96.9\%)$ desired more educational opportunity about CBR. Example, once or twice a year$(56.2\%)$ and training period of 4-7 days $(43.7\%)$. They wanted to learn theory and practice together$(74.2\%)$ and $74.2\%$ wanted the mational multi-rehabilitation center as a educational managing organization. Sixth, The most important requirment for accomplishing CBR by physical therapists was job security and an adequate number of therapists$(84.4\%)$ Required number of physical therapists in the PHC was 3 $(43.7\%)$. The cooperative agency should be the district goverment organization $(56.2\%)$. Factors inhibiting the execution of CBR were lack of administrative support, physical therapists, and equipments for pain control and for therapeutic exercise.
