The number of the functionally disabled elderly has been increasing in Korea and their families should have been in charge of supporting and taking care of them. This study was designed to grope for devices which were helpful to improve the psychological welfare of the functionally disabled elderly in the present situation. The results of this study were as follows: First, considering the level of psychological welfare of the functionally disabled elderly, the depression degree of the subjects was 52.9 which was higher than the middle point, 50. And the degree of family support the functionally disabled elderly were aware of, it also was high ; the score was 34.6 compared to the middle point, 33. On the other hand, the degree of public support that the functionally disabled elderly received was 2.01 which was lower than the middle point, 4.5. Second, the level of the depression of the functionally disabled elderly followed by background variables, the degree of agreement with family support, and public support represented significant differences among group according to religion, the type of previous occupation, the ownership of house, the type of residence, the presence of spouse, education level, and the source of income. Third, the relative influence toward the depression of the functionally disabled elderly was shown in the order of importance as follows: family support, the degree of functional disability, the ownership of house, public support, the presence of spouse, the source of income, the number of daughters, the degree of functional disablity.

The first purpose of this study is to distinguish difficult chapters in 'Speed of objects' chapter and find the factors which give difficulty to the teachers and students. Also, it attempts to compare the students' assessment scores with the degree of difficulty in teaching and also with the degree of difficulty in learning. This report is expected to help science teachers develop their PCK(Pedagogical Content Knowledge) for teaching the chapter professionally. 15 teachers who had taught the 'Speed of Objects' chapter and their 386 students took part in the survey to acquire information about the difficulties in teaching and learning. 386 students also received a test to examine their understandings of the chapter. The results of this study are as follow; First, the degree of teachers' and students' difficulty is only affected by the contents, and the degree of onerousness felt by teachers is higher than that of students. Second, The topics caused higher difficulty to teachers were 'Understanding the meaning of motion(2nd lesson)', 'Understanding the meaning and unit of speed(5th lesson)', 'Changing unit of speed(6th lesson)', 'Drawing a distance-time graph(7th lesson)', and 'Understanding the relative motion(10th). The topics that led higher difficulty to students were the contents of 5th, 6th, and 7th lessons. Third, the 'Speed of Objects' chapter can be divided into 4 types of difficulty according to the degree of teaching and learning; 'Strong difficulty', 'Learning difficulty', 'Weak difficulty', and 'Teaching difficulty'. Last, students showed low achievement to the tasks that were related with 'Strong difficulty' and 'Teaching difficulty'.

The purpose of this study was to investigate the differences of the general characteristics of subjects, the utilizing realities and the degree of satisfaction in the shopping mall and purchasing intention between group I that specializes in fashion design and group II that doesn't specialize in it. The results are summarized as the following six aspects. First, as a result of the general characteristics of subjects and the utilizing realities, the most different variables were the visiting frequency and the goods purchasing frequency. The result indicated that group II took more interests than group I. Second, as a result of the degree of satisfaction according to the factors of the general characteristics of subjects and the utilizing realities in the shopping mall, both group I and group II showed high degree of satisfaction in factor 1 (variety of event) whereas both groups showed relatively low degree of satisfaction in factor 3 (variety of goods). Third, as a result of the degree of satisfaction according to the general characteristics of subjects and the utilizing realities, group I showed significant differences in the degree of satisfaction according to a monthly allowance of pocket money and goods purchasing frequency and group II showed significant differences in the degree of satisfaction according to grade, the utilizing reason, goods purchasing frequency. Fourth, as a result of purchasing intention of fashion goods according to the general characteristics of subjects and the utilizing realities, group I showed the higher purchasing intention of fashion goods in group that the terms of payment was on-line payment than group that they was credit card. On the other hand, group II showed a significant difference in grade, which showed that group that was above third grade had the higher purchasing intention of fashion goods than group that was under third grade. Fifth, as a result of purchasing intention of fashion goods according to the degree of satisfaction, group I showed significant differences in factor 1 and factor 3 among the degree of satisfaction. In other words, group that had high degree of satisfaction in factor 1 showed the higher purchasing intention of fashion goods than other groups and group that had medium degree of satisfaction in factor 3 showed the higher purchasing intention of fashion goods than other groups. In group II, on the other hands, group that had high total degree of satisfaction showed the higher purchasing intention of fashion goods than other groups. Sixth, as a result of relative influencing power of independent variable with respect to purchasing intention of fashion goods in group I, the higher degree of satisfaction in factor 1 and the lower degree of satisfaction in factor 3 showed, the higher purchasing intention of fashion goods showed. As a result of relative influencing power of independent variable in group II, however, the higher grade and the higher degree of satisfaction in factor 1 showed, the higher purchasing intention of fashion goods showed.

Until now, most of studies on Electronic Data Interchange(EDI) have been focused on the introduction of EDI and the performance of EDI. But recently, there have been increasing researches on diffusion of Electronic Data Interchange. The aims of this study are twofold. First, to find the impacts of various factors on EDI diffusion, second, to examine the relationship between EDI diffusion factors and EDI diffusion degree. To accomplish those aims of study, two kinds of methodologies are adopted in the studies, First, model building by wide investigation on previous papers, Second, empirical research for finding the determinants of diffusion of EDI. The results of testing the hypotheses of this research are summarized as follows. First, The important EDI diffusion variables influencing internal diffusion of EDI consist of top management support, scope for EDI, IS sophistication, compatibility, complexity, relative advantages, competition intensity and external pressure. Second, Top management support, scope for EDI, IS sophistication, compatibility, relative advantages, competition intensity and external pressure are associated with external diffusion of EDI. We are aware of the important fact that top management support, scope for EDI, IS sophistication, compatibility, relative advantage, competition intensity and external pressure were simultaneously associated with internal and external diffusion of EDI.

A milling process with 45 degree chamfered inserts produces a perfect flat surface only in theory. It is due to many unwanted factors including thermal effect, dynamic effect, the problem of the controller used and the problem of accuracy of the machine tool. In this study, introduced is a method to improve the surface roughness by redesigning of the chamfer angle of the insert, which traditionally has been 45 degree. First, the relationship between the fixed machine coordinate and the relative coordinate on the insert is derived. This transfer matrix is used to determine the new insert angle to maximize the flatness of the machined surface. A newly designed insert is manufactured, and used to carry out the experiment. It is proved that she insert designed by the proposed method produced a much flatter surface than a traditional one.

The standard issue in the information and telecommunication industry is increasingly important with the rapid development of technology. This paper proposes an index model which can measure the degree of standardization in the Korean information and telecommunication field. We first classified ICT sector into 14 sub-sectors. Then for each sub-sector, we considered a set of important determinants to measure the level of standardization, and constructed a linear equation using this set of determinants. Finally we estimated the relative degree of importance of each determinant using the AHP methodology. The proposed model found that overall level of standardization in the Korean ICT industry is relatively low, and ‘IMT-2000 technology’ and ‘computer network technology’ among 14 sub-sectors are highly standardized sub-sectors. The validity of the proposed model was also partially proved using two different methods, holistic and historical approach.

This paper explores factors associated with multiple concurrent care and education arrangements in early childhood in South Korea. It draws on a subsample from the Korean Longitudinal Survey of Women and Families. Results show that about one-fifth of the families utilized multiple arrangements for their first preschool child. The primary non-parental option in multiplicity was nurseries or kindergartens. Home care and education options such as home study materials were found to be most prevalent secondary non-parental option, followed by services at private institution as well as relative care. Children's age, care cost, non-parental care time and time constraints were found to be positively related to the incidence of multiplicity for the first preschool child while family income and cost constraints were negatively associated. As a secondary option in the multiplicity, services at private institutions increased with children's age, care cost and when the grandparents live far from the parents' house. Home care and education utilization was found more among mothers with low degree of time constraints. Utilization of relative support decreased with the children's age and meant lower care cost and increased with mother's employment, fathers' education, family income, cost constraints and when grandparents live nearby. This paper, based on the associated factors, suggests how issues of children enrichment and constraints might be related to the multiplicity.
