This study examined the effect of preschooler's emotional intelligence, child-teacher relationships (intimacy, conflict and dependency) on children's social competence. A sample of 269 children (142 boys and 127 girls) aged 3 to 6 in Seoul or Gyeonggi-do participated in the Emotional Intelligence Scale, the Child-Teacher Relationships Scale and Social Competence Scale by teachers. Descriptive statistics, t -test, Pearson's correlation analysis and regression analysis analyzed data via SPSS ver. 20.0. This study followed a mediated effect model. The results showed that: (1) The emotional intelligence of girls was significantly higher than boys. However, the child-teacher relationship and children's social competence had no significant difference relationship to gender. (2) There was a mediating effect of child-teacher relationships between preschooler's emotional intelligence and social competence. The effect of emotional intelligence on social competence was partially mediated by intimate relationship, conflict relationship and dependency relationship. The degree of mediating effect was investigated in regards to conflict relationship, dependency relationship and intimate relationship. This study demonstrated that child-teacher relationships mediate the relationship between emotional intelligence and social competence of preschoolers.

본 연구에서는 누적강우을 고려한 침투수 거동을 평가하기 위해 ADR 측정센서와 간극수압계를 사용하여 흙매질의 물성 변화를 측정하였다. ADR 측정센서의 측정 정밀도를 향상하기 위한 의존성 파악 및 강우조건에 따른 흙매질 특성 변화를 분석하였다. 또한, 강우/비강우조건 하에서 모형사면 내 침투수 거동 특성도 함께 검토하였다. ADR 측정센서를 활용한 체적함수비 의존성 검토 실험의 결과는 표준사와 화강풍화토에서 체적함수비 증가에 따라 측정전압도 함께 증가하였다. 온도 의존성 검토의 경우, 고함수비 조건인 체적함수비 0.15에서 0.45 범위에서는 측정 대상 매질의 온도를 고려해야만 한다 모형사면 실험에서는 누적강우조건하에서 체적함수비와 간극수압의 변화 양상을 충분히 확인하였다. 특히, ADR4와 PWP3이 설치된 모형사면 하단부에서 측정치가 높게 나타나는데, 이것은 누적강우에 의해 발생된 침투수가 사면 하단부에서 유출면으로 작용하고 있으며, 모형사면 파괴의 시작지점으로 작용함을 알 수 있다.

The objectives of this study were to characterize the health status, the requirement of home nursing care, and dependency of daily life of the elderly so that the result could be used to provide basic data necessary for establishing home nursing care practices. The study subjects were 249 elders over 65 years old who resided at home in low income areas of three districts in Pusan. The field survey was conducted from December 27, 1993 through January 27, 1994, with a structured questionnaire. Statistical analysis was done by X²-test and Student's T-test using SPSS/PC/sup +/ program. The result were as follows; 1. Alcohol drinking rate was 50.0% for men and 27.7% for women, and cigarette smoking rate was 77.8% for men and 27.1% for women. 92.9% of elders aged 65-75 exercised regularly as compared to 81.9% of elders aged 75 and over(p<0.05). 2. 63.9% of male and 85.9% of female elders had chronic diseases showing singnificant differences(p<0.01), and both sexes had 1.7 kinds of chronic diseases in average; musculoskeletal diseases were the most common in 25.7%, while 6.8% of the elderly had cardiovascular diseases. 3. Partially movable elderly was 6.9% for men and 6.8% for woman, showing 47.1% of causes being cerebrovascular accidents. 4. The home nursing requirement was the highest for medication(66.3%), intramuscular injection(53.8%), and measurement of blood pressure·body·temperature·pulse rate(47.0%). 5. Among Physical Activities of Daily Life, bathing(10.4%) and movement(4.0%) showed high dependency rates, and among Instrumental Activities of Daily Life, phone calling(25.3%), shopping(24.5%), going out by bus(22.5%) showed high dependency rates. 6. For five categories of home nursing showing high requirements such as physical health examination, blood pressure·temperature·pulas rate measurements, medication, and intravascular injection, the requirements were different by age groups, education, and marital status(p<0.05).

Students approach mathematical problem solving in fundamentally different ways, particularly problems requiring conceptual understanding and complicated strategies. The main objective of this study is to compare students' performance with different thinking styles (Field-dependent vs. Field independent) in mathematical problem solving. A sample of 242 high school males and females (17-18 years old) were tested based on the Witkin's cognitive style (Group Embedded Figure Test) and by a math exam designed in accordance with Bloom's Taxonomy of cognitive level. The results obtained indicated that the effect of field dependency on student's mathematical performance was significant. Moreover, field-independent (FI) students showed more effective performance than field-dependent (FD) ones in math tasks. Male students with FI styles achieved higher results compared to female students with FD cognitive style. Moreover, FI students experienced few difficulties than FD students in Bloom's Cognitive Levels. The implications of these results emphasize that cognitive predictor variables (FI vs. FD) could be challenging and rather distinctive factor for students' achievement.

Various hybrid dampers have been developed in Korea to control the vibration due to a wind and earthquake. In order to minimize the installment space, cost and construction process, the new hybrid friction damper is developed. This hybrid damper is composed of several rotary friction components having two frictional joint. Because of these components, the building vibration due to wind and earthquake can be mitigated by hybrid friction damper. In this paper, various dependency tests were carried out to evaluate on the structural performance of two joint rotational friction component of the hybrid damper. Test results show that two joint rotational components do not depend on a displacement and a frequency of forcing but friction coefficients is reducing as a clamping force is increasing.

Purpose: This study is to examine the effect of auricular acupressure therapy on smoking cessation for male adult in rural areas. Method: Research design was nonequivalent control pretest-posttest design. The samples were 90 male adults(Experimental: 40, Control: 40) in a community. Measures were the number of cigarette smoking per day, dependency on nicotine, and need for smoking. Auricular acupressure therapy, experimental treatment was applied for 2 weeks, 2 times/week, 3 day/time. Data were collected from June 2005 to December 2005. Data were analyzed using SPSS PC+ 12 version. Descriptive statistics, independent t-test, ${\chi}^2-test$, were used for each aim of this study. Results: The number of cigarette smoking per day (t= 13.230, p=.000), dependency on nicotine (t=-29.743, p=.000), and need for smoking (t=-19.799, p=.000) were significantly decreased in the experimental group by application of the auricular acupressure therapy. Conclusion: Auricular Acupressure Therapy can be a better effective primary nursing intervention on smoking cessation for male adults in rural areas through reverification by a study of repetition.

Records from a total of 202 crossbred pigs were classified by their ear type and coat color to examine the presence of interrelationships with growth performances. Crossbred pigs were F2 generations of full sib family out of ten Landrace sows bred by 5 Korean domestic boars. Heavily drooped ear type was predominant, 195 out of 202 pigs over the other two types (1 straight and 6 slightly drooped). Coat colors were classified as four categories, all white, all black, dominant white or dominant black. Ratio among coat color categories did not fall within Mendelian principle of independence regarding two loci involved. There was dependency between ear type and coat color. However, due to rarity of ear types other than heavy drooped, dependency comes from distribution of those rare ear types. Three least squares models to test the effect of ear type and coat colors on growth performances were analyzed. First model analyzed effects on birth weight, body weight at 3 and 6 weeks and ADG' before weaning and between 3 and 5 weeks of age. This model included sex in addition to ear type and coat color. Second model analyzed postweaning growth traits (initial weight, final weight and ADG between these periods) upon initiation of performance testing. This model included effects of sex, test group and start age (as a covariate) in addition. Third model was fit for fasted weight before slaughter and included the effects of sex, test group and age at slaughter (as a covariate). The effects of sex and ear type were not significant source of variation for all traits. Test group was a significant source of variation for all the postweaning traits. Effect of coat color was not significant until the initiation of performance testing and became significant then after. Least squares means of dominantly black pigs were significantly lower than the other three coat colored pigs in final weight around 195 days of age and in ADG from the start of performance test and final weight measure.

Recently expanded and enhanced software system inevitably demands serious managerial considerations on its maintenance cost. This study proposes a systematic and thorough assessment model for software development methods to the end of maintainability, incorporation ISO 9126 quality standards-based criteria. The Analytic Network Process (ANP) is employed in our model to find the effect of any dependency among the items of the criteria and the alternative methods. This study then applies the model empirically in order to evaluate the efficacies of the Structured Method and the Objected-Oriented Method. At first, this study performs the test on the existence and direction of any dependency under the three types of assumptions, and then determines the relative dominance of the two methods.
