  • The purposes of this study were to determine the relevant nursing needs of patients following discharge; to identify the degree of their nursing needs; to identify types and status of discharge order and information given to patients; and to determine their specific nursing needs according to their diagnosis. In addition, opinions toward home care services provided by hospitals or by public health nurses and appointment plans with their physicians were also asked in order to determine the necessity of follow-up care for the patient after discharge. Nine hundred and eighty eight subjects were collected among patients being discharged from one national university hospital and four city hospitals. Data were collected from June,1979 to December,1979 using questionnaires and interviews. On the bases of these data the following findings were observed; 1) Almost 40 percents of total subjects discharged from the hospital with some or great degree of nursing needs in general. The most problematic nursing needs were needs for comfort which include needs for releaving pain, for sound sleep and rest, because these needs can only be met by professional help. More than 50% of total subjects have this problem. 2) Needs for mental health, general metabolism, general hygiene and activities and safety were observed in more than 20 percent of subjects. 3) Discharge orders on diet and oral medication were recorded in patients' charts in 70% of all cases. However, more than fifty percents of patients have not been told these information from doctors or nurses. Even though some of them might have had appointment plans with their physicians, they would not keep the appointments unless they completely understood the necessity of the follow-up care. If they have not had any appointment or would not visit the out-patient clinic, there is no method of caring them and prerenting funther discomfort or complications. Even in injection, ski care, dressing and bath, only one thirds of the subjects having recorded discharge orders understood what they need after discharge. The rest of cases have not known what to do for their further care. 4) More than 80 percents and 70 percents of total subjects agreed to a system of home care services provided by hospitals or public health nurses respectively. That is, regardless of sources of medical expenses, most of patients wanted to be taken care of at home following discharge. 5) While more than half of the patients having benefit of medical insurance or paying fully by themselves had appointment plans with their physicians, only one thirds of the patients fully or partially paid by government had appointment plans with their physicians. These results ex-plain that the appointment plan is directly associated with their economic power. This indicates that the home care services are more needed to the people with lower economical status. 6) Those who have been in the hospital more than 24 days wanted !o have home care services more than those who had less hospital days. They also had more appointment plans than other groups. 7) More than 70 percents of the subjects who had been in a university hospital and approximately 30 percents of the subjects in the city hospitals had appointment plans with their physicians. 8) Those who had the cerebrovascular disease, cancer or hypertension demanded more nursing needs such as needs for comfort, for general metabolism and for mental health. 9) Factors which were associated with the degree of patients' nursing needs were age, duration of hospitalization, opinion toward home care services given by public health nurses, hospital appointments and types of hospital. That is, the older they were and the longer the periods of hospitalization were, the higher were their nursing needs. The more they had nursing needs, the more they wanted to have nursing services and had appointment plans. It can be concluded that there is a great demand for a positive and systematic home care services to the people who have been discharged from hospitals following critical care. This program is definitely demanded for the low income groups of people with less education with the financial assistance of the government or other funding agencies.

  • The purpose of this thesis is to provide the framework of the health education curriculum on a school level which should be accomplishe in futrue and farthermore to establish the health education as a independent and regular course. The relation among the status in quo and the satisfaction degree of health education, the degree of the knowledge about health, the degree of the understanding of the health education and the degree of requirement for the health education curriculum has been analyzed in this paper. The research has been carried out through the questionnaire forms distributed to the girl students and the instructors at a few general senior high school and vocational senior high schools in Seoul, and the consequences are as follows : 1. As to the degree of understanding of the health education, it has been indicated that the health education should be performed one or two hours a week from the elementary school for all the boy and girl students by the experts trained in the departments concerned with health. 2. Concerning the degree of requirement for health education curriculum, the high school girl students have shown the need for first aid, sex education, environmental health, drinking, smoking, drug abuse, maternal and child health, industrial health, safety health, mental health, growth & development, epidemiology, the old health in the order named. On the other hand, the instructors have shown the need for drinking, smoking, drug abuse, sex education, maternal and child health, public health and industrial health also in the order named. The items having low degree of requirement are biostatistics, community health and health administration in case of the gril students and biostatistics, health administration and health economics in case of the instructors. 3. The status in quo and the satisfaction degree of the health education has proved higher in senior high school curriculums than in junior high school curriculums, and the most instructive course about health has turned out to be gymnastics in junior high school and the training course in senior high school respectively. 4. As to the degree of understanding of the health education in case of the girl students, the significance has been found between the health condition and the time for performing the health education, the monthly income and the objects for the health education, and the school records and the school hours per week. The significance has been shown only in regard to the school records in case of the degree of requriement for the health education curriculum. 5. The degree of requirement for the health education in case of the instructors has shown the significance between the teching career and the need for the health education. In addition, the degree of requirement for the health education curriculum has indicated significance with regard to sex and age. 6. The degress of the understanding of the health education according to the degree of knowledge about health and the degree of requirement for the health educatio curriculum have been all turned out to be statistically significant. 8. Among the factors which have an influence on the degree of the understanding of the health education, the recognition of the relation between the health course and the training course has significatly influenced the selection of the health education instructors. In additon, the understanding of the need for the health eduation has significantly influenced the objects for the instructors and the school hours, and the understanding of the need for establishing the health education course has significatly influenced the time for performing the health education.

  • As the lifestyle of consumers changes and the need for various products increases, new products are being developed in the market. Each household owns various home appliances which are purchased through the choice of a decision maker. These appliances include not only large-sized products such as TV, refrigerator, and washing machine, but also small-sized products such as microwave oven and air cleaner. There exists latent correlation among possession of home appliances, even though they are purchased independently. The purpose of this research is to analyze the effect of demographic factors on the purchase and possession of each home appliances, and to derive some relationships among various appliances. To achieve this purpose, the present status on the possession of each home appliances are investigated through consumer survey data on the electric and energy product. And a multivariate probit(MVP) model is applied for the empirical analysis. From the estimation results, some appliances show a substitutive or complementary pattern as expected, while others which look apparently unrelated have correlation by co-incidence. This research has several advantages compared to previous literatures on home appliances. First, this research focuses on the various products which are purchased by each household, while previous researches such as Matsukawa and Ito(1998) and Yoon(2007) focus just on a particular product. Second, the methodology of this research can consider a choice process of each product and correlation among products simultaneously. Lastly, this research can analyze not only a substitutive or complementary relationship in the same category, but also the correlation among products in the different categories. As the data on the possession of home appliances in each household has a characteristic of multiple choice, not a single choice, a MVP model are used for the empirical analysis. A MVP model is derived from a random utility model, and has an advantage compared to a multinomial logit model in that correlation among error terms can be derive(Manchanda et al., 1999; Edwards and Allenby, 2003). It is assumed that the error term has a normal distribution with zero mean and variance-covariance matrix ${\Omega}$. Hence, the sign and value of correlation coefficients means the relationship between two alternatives(Manchanda et al., 1999). This research uses the data of 'TEMEP Household ICT/Energy Survey (THIES) 2008' which is conducted by Technology Management, Economics and Policy Program in Seoul National University. The empirical analysis of this research is accomplished in two steps. First, a MVP model with demographic variables is estimated to analyze the effect of the characteristics of household on the purchase of each home appliances. In this research, some variables such as education level, region, size of family, average income, type of house are considered. Second, a MVP model excluding demographic variables is estimated to analyze the correlation among each home appliances. According to the estimation results of variance-covariance matrix, each households tend to own some appliances such as washing machine-refrigerator-cleaner-microwave oven, and air conditioner-dish washer-washing machine and so on. On the other hand, several products such as analog braun tube TV-digital braun tube TV and desktop PC-portable PC show a substitutive pattern. Lastly, the correlation map of home appliances are derived using multi-dimensional scaling(MDS) method based on the result of variance-covariance matrix. This research can provide significant implications for the firm's marketing strategies such as bundling, pricing, display and so on. In addition, this research can provide significant information for the development of convergence products and related technologies. A convergence product can decrease its market uncertainty, if two products which consumers tend to purchase together are integrated into it. The results of this research are more meaningful because it is based on the possession status of each household through the survey data.

  • This study is aimed at identifying the national economic value of the irrigation facilities by reviewing the existing papers on economic values of the irrigation facilities and presenting current status of dual O & M problems of the irrigation facilities. This study suggested the unified O & M system rather than continuing the existing dual O & M system of irrigation facilities based on the surveyed results of the activities of irrigation fraternities in Chungnam Province. The findings and proposals for the successful unified and mono O & M system of the irrigation facilities are as follows: (1) Total number of irrigation facilities in the nation accounts for 67,582, while the total length of irrigation and drainage canals amounted to about 174,259km. On account of the total length of structural canals was estimated at 31%, much losses of water and much O & M costs have been inevitable for the full irrigation rice culture. In spite of the past heavy investment for irrigation facilities, the ratio of rain-fed and partially irrigated paddy fields accounts for 23% in 2003. Both Korea Agricultural and Rural Infrastructure Corporation (KARICO) and the city and Gun Governments have managed the irrigation facilities separately by irrigation fraternities. The KARICO have commanded 59% of irrigation paddy area with 18% of the total irrigation facilities, while the city and Gun governments covered 41% of irrigation paddy area with 82% of the existing number of irrigation facilities representing small and medium scale. (2) The 1999 demand prices of irrigation water per ton expressed in 2000 constant market price was estimated at 388 won, the supply price was amounted to 184 won per ton. Considering the supply and demand curve of the irrigation water, the existing irrigation facilities could not satisfy the demand of irrigation water. (3) In 1999, total present added value of the irrigation facilities during the economic life accounted for 48 trillion won, while total supply cost was 44.7 trillion won. The marginal benefit and cost ratio of irrigation water was 1.08. (4) The total O & M cost per year amounting to 681.1 billion won have been required to maintain and repair the existing irrigation facilities in Korea. For the successful unified O & M of irrigation facilities covering whole irrigated paddy field in Korea, 950 billion won of O & M costs are required to keep up the marginal benefit of irrigation water as 2,800 billion won per year. The total O & M cost as 950 billion won should be allocated 40%, 380 billion won for O & M costs of irrigation facilities and 60%, 570 billion won for improvement of irrigation facilities. (5) The study investigated and reviewed the present O & M status of the irrigation facilities by small and medium irrigation fraternities. Most of the farmers belong to the irrigation fraternities preferred not only unified O & M but also KARICO take-over of the whole O & M activities of the irrigation facilities. The prevailing O & M cost per 10a expended by the Corporation was amounted to 104,890 won, while that of city and Gun governments was only amounted to 4,600 won per 10a. regarding the small amount of O & M cost expended by city and Gun governments, it is evident that the existing irrigation system have been managed ineffectively and deteriorated the facilities comparing that of KARICO. In conclusion, the Government could not satisfied the demand of irrigation water by suppling water with existing irrigation facilities. Therefore new additional investment and financial support for irrigation water development should be made to convert rain-fed and partially irrigated paddy fields into fully irrigated ones. The operation and maintenance cost should be supported to keep the marginal values of rice production of existing irrigation facilities in the national economy and to modernize the obsolete irrigation facilities. By unifying the existing dual O & M systems, all the farmers belong to the irrigated paddy fields have to be equally benefited and could be increased their farm income and be stabilized their rural lives.
