  • Purpose: This study is a descriptive and comparative study that compares health state and school adaptation between children in divorced family and in normal family. Study results will provide a basic data for the development of an intervention program designed to help children in divorced family adjust to their crisis. Method: The study subjects consisted of 700 children in 4th. 5th or 6th elementary school grade, residing Seoul and Kyunggi regions. Among these subjects, 123 were children with divorced family and 577 were children with normal family. The health status of the subjects was measured by Health Symptom Questionnaire developed by Shin and revised by the investigators. The instrument consisted of 30 items measuring physical and emotional health symptoms. The level of school adaptation of the subjects was measured by School Adaptation Scale developed by Lee, which consisted of 4 dimensions with 20 items what measures relationship with peer students, learning activity, observance of regulation, and participation of school activity. The investigators visited the schools and collected data in the classes using the questionnaire after explaining the purpose and procedures of the study to the children. The data were analyzed by descriptive statistics, $\yen\"{o}2$-test, t-test, ANOVA using the SPSS PC + statistical program. Result: First, the mean health state score in children with normal family (M=11.99) was higher than that in children with divorced family (M=19.15), showing a significant difference (t=-6.51, p=.000) between the two groups, which suggests that children with normal family have better health state than children with divorced family. Second, the mean school adaptation score in children with normal family (M=38.99) was higher than that in children with divorced family (M=26.97), showing a significant difference between the two groups (t=104.07, p=.000), which suggests that the school adaptation of children with normal family is better than that of children with divorced family. Third, in comparison of health state between the two groups by general characteristics. there were significant differences between the two groups in sex. the most contributing factor to health status of the children, school year. birth order, religion, school achievement, amount of monthly pocket money, parents level of formal education, occupation of parents, economic status (p<.05). Forth, in comparison of the level of school adaptation between the two groups by general characteristics, there were significant differences between the two groups in most variables (p<.05), suggesting that children with normal family had better capacity of school adaptation than children with divorced family. Conclusion: As a result. this study showed that the parent's divorce had great influence on children's health status and school adaptation capacity. The implication for nursing is that there is a need to develop supportive interventions for the high-risk children who have decreased health states and school adaptation capacity due to the divorce of their parents. In addition, it is recommended that further studies should be conducted to explore protective factors for the prevention of health and adaptation problems in children.

  • This study was conducted to find the mediating effect of self-leadership in the relationship between academic self-efficacy and college-life satisfaction of Chinese students majoring in beauty. Surveys were answered by 400 Chinese students from July to August 2019 and analyzed as follows. We used the SPSS22.0 program and Process macro for SPSS to analyze the frequency, descriptive statistics, correlation analysis, and bootstrap method. The results of the analysis showed a positive correlation among the college-life satisfaction, self-leadership, and academic self-efficacy of Chinese students, and self-leadership acted as a partially mediating variable between academic self-efficacy and college-life satisfaction. Therefore, it was found that a higher college-life satisfaction and self-leadership resulted in a higher academic self-efficacy. Based on these results, in order to alleviate the problems of college life maladjustment and low learning efficiency of Chinese students majoring in beauty, the development of self-leadership education programs is becoming more important. This must be emphasized in the Edu-Tech era due to the need for customized education programs for international students amidst the COVID-19 pandemic.

  • This study compares the differences of the fit factor by the order of wearing preference between Particulate filtering facepiece respirators(PFFR) and glasses when participants wore simultaneously and a survey of physical and visual complaint. Recognition level about fit of respirators was investigated and the educational (before- and after-) effect of the fit factor. When participants wore PFFR and glasses, physical complaints were nose pressure, slipping, nose and ear pressure, ear pressure and rim loosen, the most highly physical complaints were nose pressure. Visual complaints were demister, blurry vision, dizziness, visual field, and lens dirty, the most highly visual complaints were demister. But, there was significant difference in physical complaint such as nose pressure(10.3%), slipping (23.0%), nose and ear pressure(14.3%), and rim loosen(16.2%), visual complaint such as visual field(13.8%) and lens dirty(32.4%). For the recognition of fit of respirators, respirators fitness, leak site, an initial point and an object, faulty factor, recognition level was higher. Fit factor was increased after education of proper wearing of respirator. Change of the fit factor was smaller compared to the normal breathing and after 6 actions in case of after education. Questionnaire consisted of general characteristics and physical/visual complaint, recognition of fit. Complaints were measured after the QNFT with multiple choices. Quantitative fit factor was measured by device and compared the result of (before- and after-) educational effect. Also, we selected to 6 actions (Normal breathing, Deep breathing, Bending over, Turning head side to side, Moving head up and down, Normal breathing) among 8 actions OSHA QNFT (Quantitative Fit testing) protocol to measure the fit factors. The fit factor was higher after the training (p=0.000). Descriptive statistics, paired t-test, and Wilcoxon analysis were performed to describe the result of questionnaire and fit test. (P=0.05) Therefore, it is necessary to investigate the quantitative research such as training program and glasses fitting factor about the wearing of PFFR and glasses simultaneously.

  • The reason that compulsory removals of a low-quality housing redevelopment such as involuntary or unintentional migration present a problem for urban communities is that whether involuntary movers adapt themselves to their new home has an influence on the urban communities that surround them. Moreover, involuntary emigrants have higher probability of choosing faulty residential areas than voluntary emigrants do. This gives rise to a problem of another residential migration for involuntary movers. In order to solve these problems, there is a need for a new housing policy that enables original residents to come back to their old community. However studies for resettlement had not conducted subjects about housing redevelopment characteristics which influences the involuntary movers directly. Instead personal microscopic characteristics such as statistics of resettlement, the moving distance, the reason of moving, improvement of living environment, had been main subjects of farmer studies. So the purpose of this study is to analyze an analysis of the relationship between resettlement and housing redevelopment characteristics. The data used in this study was obtained at 47 areas designated by Seoul (metropolis) since 1990 for redevelopment. Cluster Analysis Is used for dividing high rate of resettlement with low rate of resettlement and Regression Analysis is used for the analysis of the relationship between resettlement and housing redevelopment characteristics. The results of examining the effects of a redeveloped housing complex on returning residents at 47 areas designated by Seoul (metropolis) since 1990 fur redevelopment are as follows: First, A housing complex with a high returning rate (remove-in rate?) has no state/public land, unauthorized building owners who are in the low-income brackets, and few interested parties such as union members. This is the characteristic of a redeveloped housing complex with a short-period project span. On the contrary, a housing complex that has a low returning rate is crowded by state/public land, and numerous unauthorized building owners, and interested parties. Second, According to the linear regression analysis, among the factors that affect returning residents, 'physical properties(characteristics) of a region', 'population properties within a region', and 'properties of a project span' indicate a negative(-)influence whereas 'properties of a complex density' shows a positive(+) influence. In a nutshell, the more the physical properties, population properties, projectspan properties, the lower the returning rate and the more the complex density properties, the higher the returning rate. In detail, an area with many small land and new/large buildings, a high population, and a long project duration has a low returning rate of original residents while an area holding large capacity and buildings with many number of floors (multiple-storied building) has a high returning rate.

  • This study was conducted in order to identify factors influencing maternal-fetal attachment among pregnant women, considering the factors presented in Mercer's theory: Becoming a Mother(pregnancy stress, self-esteem, dyadic adjustment, sense of mastery, antepartum stress). The data was collected through structured questionnaires from 140 pregnant women who visited the obstetric clinic and public health centers in a metropolitan area to have prenatal tests from August 23th to November 25th 2014. The data were analyzed by SPSS 20 software using descriptive statistics, the t-test, ANOVA, the Pearson's correlation coefficients and a stepwise multiple regression. The results were as follows: Maternal-fetal attachment in the group of pregnant women under 30 years of age was significantly higher than that in the group of over the age of 31(t=2.79,p=.004). Primiparas had higher maternal-fetal attachment than multiparas(F=3.27, p=.041). There was a negative correlation between pregnancy stress(r=-0.22, p=.009) and maternal-fetal attachment. Self-esteem (r=0.45, p<.001), dyadic adjustment(r=0.42, p<.001), sense of mastery(r=0.24, p=.005) and maternal-fetal attachment were, however, positively correlated. It was found that self-esteem, dyadic adjustment and age were some of the factors influencing maternal-fetal attachment among pregnant women. These variables explained 26.1% of the variance in maternal-fetal attachment. Findings of this study indicate needs for comprehension and assessment of self-esteem and dyadic adjustment in pregnant women through prenatal tests. Also, the intervention programs to improve maternal-fetal attachment among older mothers should be developed and implemented.

  • The recent problems of adolescents are leading us to amphasize school mental health program. Therefore, for the first step of that program, this study was attempted to find out the students' daily life stress, their adaptation beharior to resolve that stress, and their self-concept which has an effect on that beharior, to analyze the relationship among those three variables, and to provide basic data which help maintain and promote students' adaptability and mental health. The subjects were 4 classes each grade, 743 students who were chosen as a sample subject among the total of 3,250 students of a junior girls' school in Seoul by stratified sampling method. The Oquestionnair surrey was done from April 1, 1985 to April 6, 1985. The instruments were (1) a part of Junghoon chois' perceptual Orientation Scale for measuring self-perception of students, (2) Rosenberg's Questionnair for measuring students' evaluation of self-esteem, (3) modified Bell's Adoptive Behavior Questionnair, and (4) the Measuring scale for stress developed by the investigator. The collected data were analyzed by using descriptive statistics, x²-test, t-test, ANOVA, and Pearsons' Correlation. The results are summarized as follows: 1. The range of mean score of self-concept, stress, and adaptation beharior is 1-5 respectively. The mean score of self concept was 3.45. The mean score of stress was 2.53, and the degree of stress was in order of the problem of study and grade marks, girl friend, appearance, and relaxation. The subjects preferred effective long-term adaptation method (Mean=2.81) to ineffective short-term adaptation method. (Mean=2.47) 2. The self-concept had the highest degree when students were 1st grade, in good health condition, taking high grade marks, both parents existing, fathers' educational level being above college, and being in high economic status. The degree of stress was significantly high when students were 3rd grade, in poor health condition, having low grade marks, being in poor economic status, and fathers' educational level being under elimentary school. In relation with adaptation method, 1st grade students used more sbort-term and long-term method, and when students had high grade marks, being in high economic status. they used more long-term adaptation behavior. 3. Two Hypotheses of this research were tested: Hypothesis 1. "The higher the students' self-concept is, the more they use long-term adaptation method." was accepted. (r=.2482, p<.01) (t=-4.99, p<.001) Hypothesis 2. "The higher the students' stress is, the more they use short-term adaptation method." was accepted. (r=.2897, p<.01) (t= -7.51, p<.001) In conclusion, a person in charge of school health can help students to adapt effectively by planning and implementing methods which highten their self-concept and lower their stress. But because the correlation among self-concept, stress and adaptation behavior was at a low level, I think that the study, which confirm the relationship of those three variables, is needed.

  • In H.264/AVC, 4$\times$4 block transform is used for intra and inter prediction instead of 8$\times$8 block transform. Using small block size coding, H.264/AVC obtains high temporal prediction efficiency, however, it has limitation in utilizing spatial redundancy. Motivated on these points, we propose a multi-dimensional transform which achieves both the accuracy of temporal prediction as well as effective use of spatial redundancy. From preliminary experiments, the proposed multi-dimensional transform achieves higher energy compaction than 2-D DCT used in H.264. We designed an integer-based transform and quantization coder for multi-dimensional coder. Moreover, several additional methods for multi-dimensional coder are proposed, which are cube forming, scan order, mode decision and updating parameters. The Context-based Adaptive Variable-Length Coding (CAVLC) used in H.264 was employed for the entropy coder. Simulation results show that the performance of the multi-dimensional codec appears similar to that of H.264 in lower bit rates although the rate-distortion curves of the multi-dimensional DCT measured by entropy and the number of non-zero coefficients show remarkably higher performance than those of H.264/AVC. This implies that more efficient entropy coder optimized to the statistics of multi-dimensional DCT coefficients and rate-distortion operation are needed to take full advantage of the multi-dimensional DCT. There remains many issues and future works about multi-dimensional coder to improve coding efficiency over H.264/AVC.

  • The purpose of this study was to investigate the relationship between thinking style and learning style of gifted children in elementary school. The subjects were 178 fourth, fifth and sixth grade elementary school students who enrolled in gifted education program. They were given the Thinking Style Questionnaire and the Grasha Reichmann Student Learning Style Questionnaire. Descriptive statistics, correlation analysis and canonical correlation analysis were performed. Results indicated that gifted students prefer legislative, judical, liberal, local, hierarchic, external thinking styles known to be related to creative and critical thinking rather than executive and conventional styles. Meanwhile, in the aspect of learning style, independent learning style than the dependent learning style, competitive style than the collaborative style, and participatory style than the avoiding style were significantly scored higher. The canonical analysis showed that thinking styles and learning styles share 59%(Rc=.77) each other, indicating the two variables had significant close relationship. External, liberal, hierarchic, judical, executive, and liberal thinking styles in the order named showed higher cross loading in the independent variable set, likewise independent, participatory, collaborative, and competitive learning styles in the dependant variable set. The results indicate that the external, liberal, hierarchic, judical, executive, and liberal thinking styles can be the significant predictors of independent, participatory, collaborative, and competitive learning styles. The implications of the study related to the gifted education were discussed in depth.

  • This study is to observe the effectiveness of the applied model and to present the improvement plan and directions for development for the case management practical model suitable for the actual condition of Korea Labor Welfare Co. and needs of the industrial injury patients. The concrete purpose of this study is: First, observe the difference of stressor experience and experience degree between the experimental group and the comparative group. Second, observe the difference of stress of the experimental group and the comparative group. Third, find out how the stress affects the support degree and satisfaction degree. Fourth, present the improvement plan of case management model, which can promote the psychosocial rehabilitation of the industrial injury patient based on the research results. The outline of the main research results identified in this study is as follows. The stressors the industrial injury patients perceived are health problems, family matters, the problems concerning hospital recuperation (hospital staff and environmental problems), economical problems, problems of coming back to society, problems with companies, problems with Korea labour Welfare Co. and other problems. And the experience of stressor was prominently lower in experimental group than comparative group in the whole problem, health problem, problems with Korea Labour-Welfare Co. and other problems. The stressor experience degree was conspicuously lower in experimental group in the whole problem experience degree, health problem experience degree, problem with Korea Labour Co. experience degree and other problem experience degree. Besides whether or not the case management is applied is having a prominent affect on the primary factor affecting the stressor experience degree, therefore the patients applied with case management has less stressor than the patient who didn't. The difference of degree of tension experienced by the stressor in both groups, the degree of stress, was not conspicuous in statistics so it shows that the application of case management in this research has not affected the degree of tension. The field which had been the most help was emotional support in help level the experimental group perceived through applying case management about industrial accident patients and recuperation, compensation problem, medical treatment problem, family matters has been helpful in this order. The help level of the whole problem was in higher level than the middle value. The stress factor which affects the case management problem settlement is the whole body of stress. The satisfaction level of help through applying case management was highest in emotional support and family matters, recuperation problem, company problem, compensation problem, and medical treatment problem was the next highest. The satisfaction level of the whole problem was higher than the middle value. The stress factor affecting the satisfaction level of help is the whole body of stress. Therefore to reduce the stress level of industrial accident patients and for them to come back to local societies, we need to reinforce the continuance and responsibility of case management model, increase staff, reinforce the role of counsel and medical treatment, intervene in the patient's plan of leaving the hospital, develop social support system and the need to establish After Care Center.

  • These studies were performed to provide some basic informations for developing an automatic system in dairy farming cattle in order that the farmers may easily and automatically detect the maintenance of pregnancy and the fact of abortion of the pregnant cows and also to find out the diseased animals with fever. As a method of automatical detection of the maintenance of pregnancy or the fact of abortion, weighing the pregnant cows was conducted from one month-pregnancy to the term using a digital balance. From the first to the 3rd month of pregnancy the body weight of dairy cows was slowly increased (less than 2% per month), then, relatively high increase (3.4% -4.3% per month) from the fourth to the seventh month followed by decrease (3.3%) in the 8th month and very low increase (0.8-0.9%) from the 9th month to the term were shown, resulting in increase of 128.8 kg (25.05%) of body weight to be compared with the first weight. More than 107, increase of body weight to be compared with the first month-weight was denoted from the 61th month of pregnancy and more than 20% increase from the 7th or the 8th month of pregnancy as wells consequently it was presumed that detection of the maintenance of pregnancy is possible from the 4th or the 5th month of pregnancy. It was possible to diagnose a cow aborted at the 6th month by continual weighing the cow from the 1st month of pregnancy. The calved cows showed considerably higher decrease of body weight even in the third week after parturition (p<0.01)to be compared with the body weight near to the term (81.8-102.0 kg, 14-16% decrease). During the same period of 8months, the pregnant cows gained 127.4 kg (24.78% increase), whereas the non-pregnant cows gained 33.0 kg (0.71% increase) to be compared with the first weight showing considerably higher increase of body weight gain in the pregnant cows than the non-pregnant cows (p<0.01). The statistics of body temperatures of dairy cattle were collected from three clinics including the Teaching Hospital of Chonbuk University and the diseases were classified simply by the major symptoms manifested, denoting the highest temperature in respiratory disease ($39.8{\circ}C$) and the lowest in alimentary disease ($39.6{\circ} C$). These informations of body temperatures were expected to be of value for early and automatical detection of the diseased animals with fever when automatic machinery would be established. The results of periodic weighing the body weight of pregnant cows while milking were also expected to be of great use for the farmers to detect the maintenance of pregnancy and the fact of abortion when the automatic system is established in the near future.
