  • The purpose of this study was to investigate the work-family reconciliation level of married women in double-income households. Specifically, the study aimed to test the positive spillover effects, asymmetry, and differential functions of work-family reconciliation. The study thus analyzed 1,114 married women in double-income households in the third-year data of the Korean Longitudinal Survey of Women and Families (KLoWF) done by Korean Women's Development Institute (KWDI), with the exception of those who were separated, divorced, or widowed from their husbands. The data were put to descriptive statistics, frequency analysis, and exploratory factor analysis using SPSS 20.0 for Windows. AMOS 20.0 was used to test the hypothesis on positive spillover effects, asymmetry, and differential functions. The analysis results confirm that work-family conflict, family-work conflict, work-family facilitation, and family-work facilitation are different concepts, thus supporting the hypothesis on positive spillover effects. Secondly, the negative effects of family on work were greater than those of work on family, whereas the positive effects of family on work were greater than those of work on family, which finding partially supported the hypothesis on asymmetry among the components of work-family reconciliation. Finally, the married women in double-income households with preschool children experienced more work-family conflict and family-work conflict than those with no preschool children, which result supported the hypothesis on differential functions between the two groups of women. The findings were combined to provide implications for the utilization of family resources, policies for work-family reconciliation, and plans for institutional supports to promote the work-family reconciliation of married women in double-income households.

The experimental design was designed non-equivalent control group, non-synchroniged design. The study method had been done by investigating the experimental group and control group through the questionnaire on 57 patients who had been in patient department in D University hospital in Pusan from January 5th 1998 to the end of February 28th, 1998. Beach ball play was carried out experimental group once per day for 10 minute's for two weeks period from Jan 1998 to Feb 1998. Data was collected before and after the experimenation. Collected data was analyzed by means of frequency, percentage, chi-square test, mean, S.D, t-test with SPSS/PC. The results were summarized as follows : 1. The 1st hypothesis : "The experimental group which received the beach ball play should be higher in depression than the control group" was supported(t=3.11, p=.003). 2. The 2nd hypothesis : "The experimental group which received the beach hall play should be higher in powerlessness than the control group" was supported(t=3.32, p=.002). 3. The 3rd hypothesis : "The experimental group which received the beach ball play should be higher in self-esteem than the control group" was not supported(t=-1.90, p=.064). 4. The 4th hypothesis : "The experimental group which received the beach ball play should be higher in activity of daily living than the control group" was not supported(t=-.47, p=.637). In conclusion, the patients who received beach ball play showed the increase in the degree of depression and powerlessness of stroke patients. So the beach ball play had been judged the nursing intervention to improve their emotional problem in stroke patients.

  • The goal of this study is to examine the sociality and school adjustment of elementary school lower-class students. The following research hypotheses were set up and addressed: Hypothesis 1: There would be significant differences in sociality of the elementary school lower-class students according to activity - making friends group counseling Program. Hypothesis 2: There would be significant differences in school adjustment of the elementary school lower-class students according to activity - making friends group counseling Program. The subjects for the study were 20 first grade students attending N elementary school in Daejeon area. The students were assigned to the two groups-experimental group(N=10) and controlled group(N=10). The experimental group received 10 sessions of the activity - making Friends group counseling program for 40 minutes by 2 times every week, and the controlled group didn't do anything. To verify the hypotheses, two tests(sociality and school adjustment tests) were administered for the pretest and post-test. Means and standard deviations obtained from these tests were analyzed with factorial covariance test using SPSSWIN(10.0). The results were as follows: Hypothesis 1 was confirmed. The scores of experimental group were significantly higher than those of controlled group in sociability, cooperation and independence, but not in observance. Hypothesis 2 was confirmed. The scores of experimental group were significantly higher than those of controlled group in teacher-student relationship, student-student relationship and classes, but not in the keeping rules. The conclusion of the result is that the program have a good effect on the elementary school lower-class students' sociality and school adjustment. Above all, along with long-term adaptability of the research, continuous studies are required.

  • Previous studies have shown that the integrated transfer function (ITF) is independent of turbulence characteristics and can be effectively applied to predict the buffeting response of elongated structures, assuming that the strip hypothesis is valid. However, existing research has not effectively identified the ITF through segment model vibration tests, and the influence of the 3D effect on the accuracy of the strip hypothesis and the characteristics of the ITF in wind tunnel tests has not been quantitatively studied. A segment model vibration measurement device that can change a test model's span-width ratio was designed in this study. An airfoil section and a streamlined box girder section structure were taken as the background, and their ITFs were effectively identified under different L/B (L denotes the turbulent integral scale and B denotes the structural width) and model span-width ratios. The influence laws of the 3D effect on the accuracy of the strip hypothesis and ITF identification in wind tunnel tests were systematically investigated. The results showed that L/B and the structural span-width ratio are two significant controlling factors that affect the accuracy of the strip hypothesis and ITF identification. The research provides an effective experimental method for accurately predicting the buffeting response of elongated structures based on ITFs identified through segment model vibration tests.

  • In this study, the factors affecting opportunism in the relationship between suppliers and key accounts were analyzed from the viewpoint of transaction cost theory, market power theory, and relationship marketing theory. As a result of the hypothesis test, Hypothesis 1 stating that demand volatility will have a positive effect on opportunism and Hypothesis 2 that transaction-specific investment will have a positive effect on opportunism were also supported. In addition, Hypothesis 3 stating that channel power will have a positive effect on opportunism was also supported. Lastly, Hypothesis 4 stating that relational commitment will have a negative effect on opportunism was not supported, along with Hypothesis 5 stating that transaction satisfaction will have a negative effect on opportunism. The theoretical and practical implications of this study are as follows. This study has identified the antecedents of opportunism by comprehensively applying the transaction cost theory, market power theory, and relationship marketing theory. In addition, this study can identify what a company should manage specifically to lower opportunism by identifying the antecedents of opportunism. The limitations of this study and the directions for future studies are as follows. First, not all of the antecedents of opportunism of key accounts have been extensively investigated from the viewpoint of the transaction cost theory, market power theory, and relationship marketing theory. In the future, it is necessary to identify additional factors. Second, the study was conducted only in the supplier's viewpoint. In future studies, it is expected that more accurate research results can be obtained by simultaneously examining not only the supplier's point of view but also the buyer's point of view.

  • Three experiments compared two hypotheses on visual selection; perceptual load hypothesis and dilution hypothesis. The perceptual load hypothesis predicts that perceptual load of task-relevant processing determines the level of task-irrelevant processing whereas the dilution hypothesis predicts that competition for limited-capacity attentional resource, not perceptual load, determines the locus of selection. To compare the two hypotheses, we investigated the influence of perceptual load in visual search on response interference by a distractor. Experiment 1 and 2 manipulated perceptual load by the set size of a search array and the colors of a target and non-targets, respectively. As a result, distractor interference decreased with a set size regardless of perceptual load. In order to further test the set size effect, Experiment 3 manipulated the perceptual categories of non-targets and a distractor. The results showed that distractor interference decreased only when non-targets belonged to the same category as a distractor. Overall, the current findings support the dilution hypothesis, but not the perceptual load hypothesis, and provide the evidence that visual selection is constrained by capacity-limited, category-specific attentional resources.

  • Health at infancy and early childhood is considered an important factor for healthy life thereafter. Concept of nursing is inclusive not only of physical care but also psycho-social aspect in order to help achieve maximum state of wellness. Statistical studies reveal concept and structure of family and home tends to change towards nuclear type, ratio of female occupancy tends to increase. These tendencies will influence the method of infants and children. Purpose of this study is to investigate the characteristics of mothers and their children with and without occupation, method of nurturing and analyse data according to various variables, in arnder to give data for care for infants and children. During the period of June 12 though July 22, 1973, 98 mothers and their 224 children; 53 mothers with occupation with 110 children and 45 mothers without occupation with 114 children were Interviewed indirectly through check list. Results of the studies are as follows: 1. Hypothesis 1 ; Tendencies of finger sucking will be greater in children of occupant mothers due to lack of maternal love. Through chi-square examination significant difference is revealed by P>0.05 level, therefore Hypothesis 1 is rejected. (X²=0.24) 3. Hypothesis 2; of occupant mothers tend to have had wanted number of children through family planning. Ratio of wanted versus unwanted children were tested and significant difference is revealed by P<0.05 1eve1. Hypothesis 2 is supported. (X²=8.398). 3. Hypothesis 3: Non-occupant mothers tend to cuddle more while feeding infants. Significant difference Is revealed through Chi-square test by P〈0.05 level. Hypothesis 3 is rejected. (X²=4.34) Conclusion and recommendations: Occupant mothers' higher degree of interest and consideration compared to that of non-occupant mothers in regard to nurturing of their children have been ascertained by this study. These results fight have come up due to the differences of socioeconomic and cultural status of respondents. Further studies on each variable between mothers with and without occupation with similar socio-economic and cultural background are recommended.
