The purpose of this study was to investigate the prevalence of EBD (Emotional and Behaviour Difficulties) and to examine relationships of EBD to family and classroom psychosocial functioning. Two studies were carried out. The subjects were 840 children aged 7 to 12 for the first study and 448 children aged 12 for the second study. CBQ for children's behaviour, FACES III for family functioning and a short version of CES for classroom functioning were used. The prevalence of EBD was 9.4% by parents, 10.6% by teachers and 2.1% by both on the basis of Korean cut-off points. It was 13.7%, 20.8% and 4.3%, respectively, based on England points. More children were identified as EBD in boys, in one-child families and in lower academic group. EBD tended to be higher with lower levels of psychosocial functioning but classroom-control. The relationships were more consistent and high with children's rather than adults' perception, and with teachers' rather than mothers' ratings. The findings were discussed in terms of the scale validity, the concept of 'open systems' and differences in the validity of ratings.

The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study. the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large genial angle in orthognathic surgical cases with skeletal Class III malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was small in male.

The present study revealed comparison the pressure distribution on the surfaces of regular cross plan shaped building with angular cross plan shaped building which is being transformed from basic cross plan shaped building through the variation of internal angles between limbs by $15^{\circ}$ for various wind incidence angle from $0^{\circ}$ to $180^{\circ}$ at an interval of $30^{\circ}$. In order to maintain the area same the limbs sizes are slightly increased accordingly. Numerical analysis has been carried out to generate similar nature of flow condition as per IS: 875 (Part -III):1987 (a mean wind velocity of 10 m/s) by using computational fluid dynamics (CFD) with help of ANSYS CFX ($k-{\varepsilon}$ model). The variation of mean pressure coefficients, pressure distribution over the surface, flow pattern and force coefficient are evaluated for each cases and represented graphically to understand extent of nonconformities due to such angular modifications in plan. Finally regular cross shaped building results are compared with wind tunnel results obtained from similar '+' shaped building study with similar flow condition. Reduction in along wind force coefficients for angular crossed shaped building, observed for various skew angles leads to develop lesser along wind force on building compared to regular crossed shaped building and square plan shaped building. Interference effect within the internal faces are observed in particular faces of building for both cases, considerably. Significant deviation is noticed in wind induced responses for angular cross building compared to regular cross shaped building for different direction wind flow.

To deepen the understanding of shear behaviour in beams without transverse reinforcement, the relative importance of five contributing factors to concrete shear resistance($v_c$), which are i)flexural compression zone, ii)friction at crack faces, iii)dowel action, iv)arch action and recently identified, v)residual tensile stresses across cracks, was explained physically using two analytical methods based on the truss concept. One is called "Modified Compression Field Theory(MCFT)" considering ii) and v) explicitly, and the other "Crack Friction Truss Model(CFTM)" more dominantly ii) in determining concrete resistance. To verify their effectiveness, the predictions using MCFT and CFTM were also made for twenty KAIST beam tests($f'_c$=53.7Mpa), designated more likely to the development of the size effect law based on the fracture mechanics concept. Experimental findings with varying of a/d, longitudinal reinforcement ratios, and obtained from MCFT enabled additional explanations for some phenomena which were difficult to measure in tests. However, MCFT seemed somewhat conservative for beams with higher longitudinal reinforcement, while somewhat unsafe for beams with larger depths. More tests are necessary leading to firm conclusions in these areas.

The purposes of this study were to classify the family types based on the intra system dynamics and to examine sociodemographic backgrounds and the life satisfaction of these families. The data were collected by means of questionnaire distributed to a stratified sample of 544 housewives in Seoul who lived with housbands and children. The questionnaire included FACES II and III Communication Scale managerial behavior scale and life satisfaction Scale. Frequency percentile mean correlation factor analysis cluster analysis one-way ANOVA with scheffe test and chi-square test were used to analyze the data. This study had resulted in four major findings. The first was that highly positive relationships were found among four intra system dynamics elements. The first was that highly positive relationships were found among four intra system dynamics elements. The second finding was that families were clustered by four types named personal-oriented enervated dynamic and managerial-orien ed family. The third finding was that the four types of family were influenced by education level and job of husbands and family income. The last one was that the differences in life satisfaction were found among four types of family. The housewives of dynamic family type showed the highest level of satisfaction whereas the lowest level of life satisfaction was found among housewives of enervated family type. The recommendations for future esearch and better ways to educate and counsel families were suggested.

The Kaes$\breve{o}$ng Industrial Park(KIP) is being developed in the region, as a collaborative economic development with South Korea. KIP construction started in June 2003, and in August 2003 North and South Korea ratified four tax and accountancy agreements to support investment. Pilot phase construction was completed in june 2004, and the KIP opened in December 2004. In the KIP's initial phase, 15 South Korean companies constructed manufacturing facilities. Three of the companies had started operations by march 2005. First phase plans envisaged participation by 250 South Korean companies from 2006, employing 100,000 people by 2007. Based on the 2009, 117 factories were employing approximately 41,000 north' workers and 1,000 south' staff. The industrial park is seen as a way for South Korean companies to employ cheap labour that is educated, skilled and speaks Korean which would make communication considerably easier. However the zone still faces a number of obstacles. In the view point of these obstacles, especially this study focused on the complementary issues for the improvement of trade goods management systems between South and North Korea. At the result of this study, it is suggested that, i) to establish portal system based on single window, ii) strengthen user-interface hands of logistic facilities, iii) stable foundations of trade and/or logistic management systems, iv) networking of IT infrastructure with South and North Korea, and so on.

Purpose: The purpose of this study was to investigate the prevalence fate of obesity and to assess the relationship between obese children and their family Characteristics in 3 rural area in the Chung Cheong Nam Do province. Method: The children's height, weight and family characteristics of 327 5th and 6th grade elementary school students were obtained from the individual health records and self-recorded questionnaire surveys from June 25th to July 15, 2004. Results: The results of this study are summarized as follows: 1. The prevalence rate of obesity of 5th and 6th grade of rural elementary school students was 10.5%. 2. 20.9% of obese children had obese family members and 9.4% of obese children did not have any obese family members. The birth order, family size and family structure showed no significantly difference. 3. The obese children were more affected by their parents' concerns of body image (upper quartile of 84.1) and exercise (upper quartile 61.4%) than normal children. However, there was no significantly increase with the parents' concerns about meals. 4. There was no relationship in the obese children by PBI. 5. There was no relationship in the obese children by FACES III. Conclusion: The elevation of a parent's concern of their obese child about meal regulation should be investigated further.

The purpose of this study was to examine children's self-regulation and their problem behavior according to family interaction types. The subjects were 227 children and their mothers, and 14 teachers in Jeonbuk. To obtain family interaction types, self-questionnaires of FACES III are given to mothers. Also, self-questionnaires of children's self-regulation and problem behavior were given to teachers. The data were analyzed by computing t-test, ANOVA, Duncan post test, and multiple liner regression. The results were as follows. First, There was a difference in the children's self regulation and problem behavior, but not in family cohesion and adaptability, according to the children's sex, age, and family variables. Second, it was found that there was a difference in self-regulation and problem behavior according to family interaction types. It showed that self-regulation was higher and problem behavior was lower in the most 'enmeshed' families in cohesion and the most 'chaotic' families in adaptability. Third, considering the relative strength of each variable on children's problem behavior, it was shown that children's sex and age had the greatest influence on problem behavior, followed by self-regulation and family's cohesion. In conclusion, it is suggested that the efforts to improve family cohesion as a psychological environment should be made in order to increase the children's self regulation and to decrease the children's problem behavior.

The objectives of this study were to examine whether there were differences in family cohesion and adaptability perceived by married women when socio-demographic variables authority patterns and sex-role attitudes changed. Dividing the family system type into two parts by the levels of cohesion and adaptability then collected data were examined to test curviliner and linear hypothesis. The subjects were 542 married women living in Pusan. The guestionnaires included FACES III Authority Pattern and Sex-role attitude scales. The data were analyzed with statistical methods such as Frequency Distribution Percentile Mean T-test and X2-test. The major findings were as follows: 1) The levels of family cohesion and family adaptability perceived by married women were high. 2) There were no significant statistical differences in the levels of socio-demographic variables Authority pattern Sex-role attitude among the groups of family system type I based on the curvilinear hypothesis but significant statistical differences were found in preferred variables among the groups of family system type II based on the linear hypothesis. 3) Among the socio-demographic variables family type religion and husband's educational level were significantly correlated with the groups of family system type II,. The percentiles of HH(the levels of cohesion and adaptability were high) families were high when the married women's sex-role attitudes leaned toward modern and authority patterns were husband-dominant.

The purpose of this study is to develop the group program model for reinforcing family relations of single-mother families as one approach to family welfare service. As previous research findings about problems of single parent families were reviewed and the framework for the program development was identified, a 6 sessions group program was planned and applied to 9 single-mother families from June 2nd to July 7th. Program evaluation questionnaire, Scales measuring powerlessness and FACESIII for family relations, social support network tool, and group process recording were used for the evaluation of this program. The participants evaluated this program as very supportive, useful, and educational. The powerlessness was reduced in a statistically meaningful way before and after the program and the result was found to be maintained for 4 months in the follow-up session. The family relations according to FACES III were mostly balanced and didn't show some significant change after the termination of this program. The single mothers had little concrete supports from others, if any, had some from relatives. They rather had to give supports for the other family members and reciprocally gave and took emotional or informational supports with friends or neighbors. Based on these results, the 2 step model consisted of brief group program and long term support group was developed and the practical methods were suggested for the single-mother families with low income.
