  • This study intended to examine the effects of each factor on teacher efficacy. A questionnaire survey was administered on 225 home economics teachers in middle school in Gyeonggi-do, and a total of 194 copies of the questionnaire excluding poorly filled-out 31 copies were used for the final analysis. A questionnaire in a self-administering design was used to collect data on individual characteristics, teacher efficacy, self-esteem, development of expertise, and educational environment of school perceived by the middle school home economics teachers. The findings of this study are summarized as follows; First, there were significant differences in teacher efficacy according to age, education and service years. Second, significant differences were found in teacher efficacy according to self-esteem, development of expertise and educational environment of school. That is, the more positive self-esteem, development of expertise, participation of parents, characteristics of students and other teachers, and teachers' perception about teaching-learning aids were, the higher home economics teachers' efficacy became. Third, the study revealed that teacher efficacy was influenced by development of expertise, educational environment of school and self-esteem. Considering these results, positive self-esteem of teachers, practical teacher training, expansion of self-development training opportunity, aids from educational authorities in terms of money and time are needed to improve teacher efficacy of home economics teachers. Efforts should be made to help teachers have positive attitudes toward parents, students, and other teachers.

  • The purpose of this study was to examine the effects of storytelling lessons using picture books on the resilience of adolescents and the parent-child relationships in the family unit of home economics subject in middle school. For this purpose, I selected picture books of five themes on family type, family relationship, family conflict, sexual violence, domestic violence, and family loss, and developed a teaching-learning process plan for 'Family class with picture book' using storytelling elements and techniques. The teaching-learning plan was applied to 194 middle school students in technology·home economics classes, and the learning effet was evaluated by comparing pre- and post-tests. As a result, the resilience level perceived by adolescents increased significantly after class, but no significant effect was found on self-expansion, which is a sub-factor of sociality. In the parent-child relationship of adolescents, the effect of instruction was shown in all areas, and the affectional bonds felt in the relationship with mother than with father showed higher increase. In the family unit of home economics, storytelling lesson through picture book seems to have a positive influence on the adolescents in their relationship with the family by bringing up the potential power in them to stand against the adversities they may face.

  • This study examines whether the variables used in the Unified Theory of Acceptance and Use of Technology(performance expectancy, effort expectancy, social influence, and facilitating conditions) is applicable to continuous usage of uTradeHub at a time of expansion in the use of uTradeHub. In addition, the role of user satisfaction(mediating effect) and CEO support(interaction effect) in the relationship is identified attempting to provide basic data to help uTradeHub management strategy establishment. A total of 101 valid responses collected through questionnaires were used for empirical analysis(using SPSS 24.0), and the results are as follows. First, for the effect of the integration technology acceptance factor on user satisfaction(H1), only performance expectancy, effort expectancy, and social influence were significant, but facilitating conditions was not significant. Second, for the effect of user satisfaction on the continued use of uTradeHub(H2), there was a significant result. Third, the mediation effect on verification of user satisfaction(H3) was full where performance expectancy, effort expectancy, and social influence prompted continuous usage through user satisfaction. Fourth, for interactive effect verification of CEO support(H4), an interaction effect was shown only in the influence relationship of performance expectancy and social influence on user satisfaction.

  • This research explores the relationship between gender equity within family and second birth in Korea. For a factor analysis on the intention of having additional children for women with one child, I have used the data from the 2005 National Survey on Marriage and Fertility Trend" of the Korea Institute for Health and Social Affairs. Among 516 samples(year of 20-44), women planning to have second birth are 54.7%, and others have answered that they have no intention to have second birth. As a result, main causes affecting progressing to second birth seemed to be family planning on family cycle, such as controlling age gaps between first and second child, composing children genders as they wish etc. The variable of "gender equity between couples" in progressing to second birth are of significant only with married working women group. In case of married working women, more the husband's houseworking hours increase, the more prone to progress to second birth. However, in case of housewives, gender equity level, such as husband's housework hours or share of housework are not of significant influence in progressing to second birth. Not only working mothers but also housewives need the realization of gender equity within the family and the expansion of social support system for work-family life balance.

  • Objectives : To identify the factors affecting users' satisfaction with the Order Communicating System(OCS) and to highlight the factors important for the successful establishment of OCS. Methods : A Users Satisfaction survey was sent to 4,513 people, consisting of 1,503 doctors, 2,379 nurses, 255 pharmacists and 370 administrative workers in 16 hospitals which had introduced OCS. The response rate was 63.9%. Measurement of users' satisfaction was peformed with the instrument which was used in Doll's study. Some aspects of Doll's instrument were adjusted according to the aims of this study. The classifying sections of this survey included age, job and status classification, computer experience, OCS education, duration of daily OCS use, type of order entering, number of personnel in the Hospital Information System's department, cost of OCS, problem frequency, proportion of work managed by hand, OCS type, and Hospital establishment type. Results : There was a positive correlation between satisfaction level and managerial status throughout all job classifications. Irrespective of the importance of OCS education as a factor relating to users' satisfaction, the additional work load caused by OCS lowered users' satisfaction. Different factors affected users' satisfaction according to job and status classification. The composition of factors affecting the pharmacist and administrative worker satisfaction levels was simpler than that of the doctor and nurse levels. There were no statistically significant differences between the actual computer experience duration of daily OCS use and users' satisfaction with OCS. Conclusions : There was an understandable relationship between users' attitude to OCS and factors affecting users' satisfaction. The results of this study could be used as a basis for the successful expansion of the operation of OCS. But more detailed studies on users' satisfaction and further improvements of methodologies are required for the successful establishment of OCS.

  • Pharynx is a system transporting foods by peristaltic motion(contraction and expansion movement! into the esophagus and functioning as airway passages. In this study, structural changes of pharyngeal dysfunction are analyzed by biomechanical model using CT and FEM(finite clement method). Loading condition was assumed that equal pressure was loaded sequentially to inside of pharyngeal tissue. In order to analyze the pharyngeal muscular dysfunction by biomechanical model. the pharyngeal dysfunctions was classified into 3 cases. Taking into account the clinical complication by neuromuscular symptoms such as pharyngeal dysfunction after stroke. we assumed that a change of material property is caused by muscular tissue stiffness. A deformation of cross sectional area of the pharynx is analyzed increasing the stiffness $25\%,\;50\%,\;75\%$ in each case on the basis of stress-strain relationship. Based on three-dimensional reconstruction of pharyngeal structure using limited factor - techniques and the optimization procedure by means of inverse dynamic approach. the biomechanical model of the human pharynx is implemented. The results may be used as clinical index illustrating the degree of pharyngeal muscular dysfunction. This study may be used as useful diagnostic model in discovering early deglutitory impediment caused by physiological or pathological pharyngeal dysfunction.

  • This study explores the trends of social security expenditures after financial crisis in welfare states. For the purpose, this study analyzes changes in social expenditures during 1980~2003 in 22 OECD countries. The results show that average total social security expenditure(as a percentage of GDP) among the 22 countries increased from 18.0% in 1980 to 22.3% in 2003. Compared to sharp increases during the great expansion period of the welfare state before 1980s, the increase in social expenditures after 1980s is substantially weakened. The slowdown in the increases of social expenditures is remarkable in the social democratic welfare states where social expenditures have already reached a high level. On the other hand, social expenditures are considerably increased in the lagged welfare states such as South European countries and Japan. As a result, the cross-national difference in social expenditures has continuously decreased. These findings suggest that financial crisis is a key factor of welfare-state reorganization. Countries where social expenditures are in high level need more reforms under the pressure of financial deficits. Since 1980s, they have tried various reforms especially in pensions and unemployment benefits. Facing new and increasing demands for social security as well as financial limitations, the welfare state needs major reforms in the social security system to increase effectiveness/efficiency of existing programs and to iron out priorities among programs.

  • It is over 12 years since the launch of Korea Train eXpress (KTX) services. Demand for the KTX has been on the increase continuously but few studies have been produced related to this phenomenon. KTX passenger demand has been constantly increasing due to influencing factors such as the expansion of network, rise of oil prices, etc. In this study, our main focus is to verify that there are other types of elements that are causing an increase in KTX demand; our approach looks at changes in social and psychological aspect that have occurred due to the reduction of travel time and cost, as well as the imposition of a five-day workweek. In other words, we considered diffusion theory in the marketing area, which affects product selection and purchasing attitudes, as a key factor that is causing passenger demand to increase. That is to say that it is hypothesized that the demand for travel on the KTX has increased due to the train's utility, which is spread by the diffusion effect Therefore, the Bass diffusion model was applied to explain the dramatic increase in KTX passenger demand. Based on this foundation, it was also discussed how certain marketing strategies that incorporate the diffusion effect should be considered variously for sustainable management of rail transportation, while considering a steady passenger demand.

  • Previously most of flood prevention efforts have been made for relatively large watersheds near to channel flow. However, as economical development and the expansion of leisure areas to mountainous region, human casualty by flash flood occurs frequently, requiring additional prevention activity. Therefore, to reduce the damage of human lives and property by flash flood, we develop an assessment method for flash flood occurrence for mountainous areas considering various factors involving it. PROMETHEE(Preference Ranking Organization METHod for Enrichment Evaluations) which is one of the MCDM(Multi-Criteria Decision Making) was adopted to assess the contribution of each factor to the risk of the flash flood in the mountainous area. The main evaluation criteria are classified into three categories, namely, the regional and rainfall characteristics, and geographical features. Also, the Entropy method is used to determine the weight of each evaluation criteria without survey. The suggested method based on PROMETHEE with Entropy method is applied to BongHwa region to verify its applicability. After applied, the method successfully assesses the relative risk of flash flood occurrence of each sub region in the BongHwa region. Out of the seventeen sub-regions, five, seven and five of them are evaluated as high-risk, medium-risk, and low-risk, respectively. To verify the results, we searched the historical data of flash flood and the flash flood had occurred in one of high-risk sub-regions at 2008.
