The effects of personal(gender, physical growth) and environmental(communication with parent, intimacy of friendship, school performance, and satisfaction of school-life) factors on adolescent's self-esteem were examined in a samlpe of 525 first and second grades in middle school. The subdomains of the self-esteem were peer-related self, home self, teacher-related self, academic self, physical appearance self, physical competence self, personality self, and general self. T-test, Pearson's correlation, and regression were used as statistical analysis. Results were as follows. First, there was evidence of a gender difference in the level of the subsdomains of self-esteem: teacher-related, physical-appearance, physical-competence, and personality. Second, the factor which was the most powerful predictor of each subdomain of the self-esteem was as follows 1) the most powerful predictor of the peer-related self was the intimacy of friendship, 2) the most powerful predictor of the home self was the communication with parent, 3) the most powerful predictor of the teacher-related self was the satisfaction of school-life, 4) the most powerful predictor of the academic self was the school performance, 5)the most powerful predictor of the physical-appearance self, the physical competence self, and the personality self was the satisfaction of school-life, 6) the most powerful predictor of the general self was the school performance.

Brassica와 Raphanus 간에 속간 교잡종을 육성하기 위해서 34개의 교배 조합을 설정한 다음 수분 12일이 경과된 배주를 BA와 GA 1.0 ㎎/L가 첨가된 MS배지에 접종하고 배의 발아율을 조사하였다. BA나 GA 첨가는 배의 발아에 큰 영향을 미치지 않았다. 무 속의 '내병총태'와 '중국청피'를 부계로 교잡한 조합에서 배의 발아율이 낮았으나 갓(Brassica juncea)을 부계로 교잡한 조합에서는 비교적 배의 발아율이 높았다. 이러한 결과는 배주배양시 배지에 첨가한 casein hydrolysate, malt extract, BA, kinetin 및 glutamine이 배의 발아에 미치는 영향보다는 부계나 모계의 교잡조합에 따라 배의 발아율에 상당한 차이가 있다는 것을 의미한다.

Using radioactive $^{40}K$ in potassium, a study was conducted to evaluate the potassium supplying power of different soil types developed on different parent materials. A conversion factor based on two parameters namely $\frac{available\;K_{soil}}{total\;K_{soil}}$ and $\frac{K_{plant}}{K_{soil}}$ was developed and found to be closely related to plant response. According to this characterization soils derived from the various parent materials were ranked as basalt >Silla series>gneiss>porphyry>granite${\gg}$schist. From the point of view of potassium response as measured by yield as similar response pattern was observed. That is, soils derived from basalt to be most responsive as compared to the other soils. The variations among the soils may be accounted for to their potassium bearing mineralogical composition and their stability.

Objectives: The Child Report of Post-traumatic Symptoms (CROPS) and the Parent Report of Post-traumatic Symptoms (PROPS) are screening measures for post-traumatic symptoms in children. The present study aimed to investigate the reliability and validity of the Korean versions of the CROPS and the PROPS. Methods: The Korean versions of the CROPS and the PROPS were administered to a sample of 304 children aged 6 to 15 years old. The internal reliability, test-retest reliability, factorial validity, predictive validity and concurrent validity were evaluated. Results: The reliability of the CROPS and the PROPS was shown to have excellent internal consistency and test-retest correlation. The single factor structure of the PROPS was good and that of the CROPS was borderline acceptable according to confirmatory factor analysis. Other validity measures such as the predictive validity and concurrent validity were also shown to be satisfactory. Conclusion: This study demonstrated that the Korean versions of the CROPS and the PROPS were reliable measures with satisfactory psychometric qualities. Because it takes less than 5 minutes to fill out the CROPS and the PROPS, respectively they can be quick and easy screening scales for assessing post-traumatic symptoms in Korean children.

The purpose of this study is to investigate, analyze the purchasing behavior of fashion goods according to life style and role model of preteen generation, and provide manager or marketing planner for the reference data so that they can understand preteen generation and make proper strategy efficiently. So called, preteen market focusing on 1014 generation (from ten to fourteen years old) is highlighted. This generation created between the year 1989 to 1993 after Seoul Olympic monopolize parent's love in abundant economic environment and rise to the core of consumption subject. Products aiming at this preteen generation continuously though consumption mind was shrunk greatly due to recession. Only 2~3 years before preteen market was regarded as grey zone which doesn't belong to not only children (between six and nine years old) but also teenagers (between fifteen to eighteen years old). But in recent day their purchasing powers have increased rapidly and age group is divided on details, so that preteen market has become a niche market. Subjects were 333 persons consisting of students in the 4th~6th grade of primary school and the 1st~2nd grade of middle school in Daegu city. Measuring instruments are as follows: 5questions to differentiate preteen generation, 22 questions to measure life style, 17questions (which have six sub-factors such as purchase motive, factor of product selection, utilization of informant, purchase time, purchase place, and purchase method) to measure the purchase behavior of fashion goods measurement, and 16 questions (which have four sub-factors such as parent, entertainer & sports stars, brothers and sisters, friends) to measure model of role. Statistical data were processed by SPSS 10.0 programs. Frequencies, Factor analysis, Cluster analysis, ANOVA, Cross analysis, Multiplex regression analysis, and Duncan's multiple range test were carried out.

Generally, as the welded region of weld structures has the incomplete bead and welded deposit which are able to behave like the surface cracks occasinally, there is a high possibility that the fatigue fracture of the weld structures is due to the surface cracks on the wlded region. This study was done to investigate the effects of post weld heat treatment (PWHT) on the fatigue behaviors of the surface crack of the heat affected zone (HAZ) for the multi-pass welds under the repetitive pure bending moment. The obtained results are summarized as follows : 1. The crack grows to the depth direction initially as the number of cylces increase, the amount of crack length is increased for the surface dir3ction and cive versa for the depth direction. 2. The fatigue life is increased in a order of as weld, PWHT specimens and parent. 3. As the number of cycles increase, the crack length is increased to th surface direction. The increase of the depth length is blunted at the center of specimen thickness. 4. The fatigue crack growth of PWHT specimens to the surface direction is dependent upon the holding time and applied stress during PWHT. In order words, the crack growth rate decreases with the holding time and increases with the applied stress during PWHT. 5. As the crack grows, the aspect formed in the course of crack propagation approaches to semicircle for parent and ellipse with the largest semidiameter for PWHT ($1/4hr, 15kgf/mm^2$) 6. At depth direction, it is difficult to apply to the paris' equation because of the scattered data between the crack growth rate and the stress intensity factor range.

Objectives: The major purpose of the study is to examine structural relation among teenager's perception of parenting attitudes, peer attachment, resilience and meaning in life. In order to achieve purpose of the study, we will develop reliable criterion which can measure variable. Method: We will set up structural relational model from relationship between internal and external variables that can influence teenager's meaning in life and we will examine the relationship between variables through structural equation analysis. we will find structural relationship among parenting attitudes, peer attachment, resilience and meaning in life. Results: We analyzed structural relationship among variables targeting 744 middle school and high school students. Teenager's perception of parenting attitudes have positive influence on peer attachment. This shows that teenager perception of fostering attitude have a positive influence even though teenager percepts parent's foster attitude as overprotective or compassionate. However, if teenager percept fostering attitude as overprotective, teenager perception of parenting attitudes doesn't have influence on resilience. Parent's compassionate attitude not only directly influence resilience but also influence resilience through peer attachment. This validates that individual psychological factor, such as how teenager accept and interpret surrounding environment can influence resilience. Peer attachment relationship not only directly influence resilience but also influence meaning of life through resilience. The resilience has direct effect on meaning in life. Conclusions: When one of education goal is to help teenager to find meaning in life and to reach self-realization, We need to have interest in resilience which is known factor for contributing meaning in life. As previous teenager studies has approached this problem, such as maladjustment, delinquency, and depression, it is significant that this study is examined in positive a psychological perspective which focus on healthy adjustment, such as meaning in life based on teenager's resilience and happiness.

Objective: The purpose of this study was to analyze correlation effect size between Basic Psychological Needs (BPN) and factors affecting BPN. Methods: This research was reviewed and synthesized systematically by meta-analyse. Fifty-eight published studies between 2008 and 2016 were sampled and the effect sizes were acquired. Results: The major findings were as follows. In general, medium correlation effect sizes were found. Competency among sub-factors of BPN showed highest effects. Parental factor was more related to BPN than school and individual factors. Parenting behavior and family psychological backgrounds were the most crucial factors in the parental factors. School adjustment was the most critical factor in the school factors. In school grade, the elementary school was more related to BPN than junior high school and high school. Conclusion: Based on these results, we suggest a number of components for parent-education programs, and information for future research.
