This study investigated the relationships between factors of aggression and satisfaction with life and the differences of irrational belief, primary secondary anger thought, and satisfaction with life among four groups classified based on the levels of hostility and verbal aggression. 268 middle school boys in Chungnam areas served as subjects. The results showed that hostility showed the most negative correlation with satisfaction with life. Stepwise regression analyses showed that hostility negatively predicted satisfaction with life, whereas verbal aggression positively predicted satisfaction with life. Factors of irrational belief, primary/secondary anger thought were negatively correlated with satisfaction with life. Analyses of variances revealed that covert hostility group showed higher scores on self-depreciation, disregard and disappointment in intimate relationship situation, hopelessness, whereas overt hostility group showed higher scores on derogation of others/revenge. In addition, covert hostility group showed lower scores on satisfaction with life than other groups. Finally, limitations of this study and suggestions for future study were discussed.

The purpose of this study were to identify the difference of demographic variables, motivation and dissatisfaction to purchase of groups who classified by frequency of purchase. Data were collected via intercept surveys conducted at nine regional branches of two major department stores situated in Seoul. Participants(n=1,120), who had previously purchased women's private brand apparel, were asked to complete a questionnaire. The results of this study were as follows; The subjects were classified into 3 groups by frequency of purchase and their demographic variables were analyzed. The customer groups of high frequency who were 18 to 39 years old had some college education, housewives and white collar workers. Their monthly household income is one to three million won and their monthly expenditure is 100,000 to 300,000 won on apparel shopping. The most important purchase motivation of lower frequency groups was design, whereas that of middle and high frequency groups was good quality over price.

The purpose of this study was to investigate, longitudinally, interruption behavior which children who do stutter (CWS), children who do not stutter (CWNS) and their mothers and relationship with disfluency of children showed during interactions with their mothers. Subjects for this study consisted of 2-5 year old CWS (male 2 and female 4), an age-matched group of CWNS (male 3 and female 3), and their mothers. Frequencies of normal disfluency (ND) and abnormal disfluency (AD) in children group and frequency of interruption and simultalk duration in children and mothers group were measured two times (initial visit and 12 months later) over the course of one year. As a result, no significant difference was observed in frequency of interruption and simultalk duration both between two mother groups and between two child groups at initial visit and 12 months later. However, frequency of interruption increased significantly over the course of one year in CWS group. A significant group difference was found in frequency of interruption of mothers but, no significant difference was observed in simultalk duration of mothers at initial visit. In the CWS·mothers group, no factors were related with disfluency of children at initial visit and 12 months later. These findings suggest that interruption is not just negative behavior, and that reducing interruption should be considered in child·parent interaction therapy for CWS.

This study aims to examine the correlations between undergraduates' major-interest congruence and stress coping behaviors and major adjustment. And in order to find there is any group violating Holland's congruence hypothesis, this paper divides them into four groups according to the degree of major-interest congruence and major adjustment. Also, it examines the difference of stress coping behaviors among the four groups. The followings are the chief results of this paper. First, according to the result of analyzing the effects of major-interest congruence and stress coping behaviors on major adjustment, congruence did not affect major adjustment significantly. Second, according to the result of dividing them into four groups by the degree of major-interest congruence and major adjustment, there is one group with high congruence but low major adjustment and also a group with low congruence but high major adjustment. Third, according to the result of examining the difference of stress coping behaviors among the four groups by the degree of major-interest congruence and major adjustment, there is significant difference among the four groups. Above results imply that in major adjustment, we should consider factors other than major-interest congruence, and stress coping behaviors are particularly important for it. Therefore, it is necessary to train their stress coping behaviors and also develop programs to facilitate major adjustment. Also, it implies that in the use of Holland's theory, it is crucial to use it based on the client's various information and uniqueness rather than to apply it in a conventional or unconditional way.

Lipoprotein lipase (LPL)은 지방축적과 대사에 있어 중요한 효소로서 지방조직과 근육 내로의 지방산 유입을 조절하며, 여러 조직에서 합성되고, 조직 특이적인 방법으로 동물의 생리상태, 영양상태 및 발달단계에 따라 유전자 발현이 조절되는 것으로 알려져 있다. 본 연구는 어류의 체지방 축적과 대사과정을 이해하고 성장 및 경제형질 관련 DNA marker를 확보하기 위한 1차적인 연구로서, 한국산 선발계통 및 일본산 양식계통과 이들 두 계통간 잡종 참돔 집단을 이용하여 LPL 유전자 내의 다형성을 탐색하고 분석하였다. PCR-RFLP 분석을 실시하여 참돔 LPL 유전자 exon 2번을 포함하는 영역에서 3개의 (Msp I, Alu I 및 Hsp92II) 다형성을 확인하였고, 각 집단간 대립유전자의 빈도를 분석하였다. Exon 2번에서 관찰된 Msp I 다형성은 염기치환 (C$\longrightarrow$G)이 일어난 형태로서 아미노산 서열에는 변화가 없는 silent mutation 이었으며, 대립유전자의 빈도를 분석한 결과, 각 집단간 뚜렷한 차이는 없었다. Alu I 및 Hsp92II 다형성은 intron 영역에서 발견되었으며, Alu I 다형성으로 인한 4개의 대립유전자형 중 D 대립유전자는 한국산 선발 계통과 한국산 선발계통을 포함하는 교배집단에서만 검출되었다. 이 후의 연구에서는 참돔 LPL 유전자의 exon 영역에 존재하는 다형성을 탐색하고, 형질과의 연관성 및 지방축적 기능과의 관련성 등을 분석하고자 한다.

This study decomposed Concentration Index(CI) and Hiwv Index(HI) of medical care utilization by subgroups: sex, age group, and region. CI and HI were decomposed into "the between group" component, "within group" component, and a residual. The results of analysis are summarized as follows; First, there was no influence of sex on the equity of medical care utilization measured by the numbers of visiting clinic. However, "within group" component of female explained .0441 among HI, .1035. This means that poor women's underutilization of medical care is the important factor in determining its degree of equity. Second, age groups had a decisive effect on the equity of medical care utilization measured by the numbers of visiting clinic. they explained -.0085 among HI, -.0170. Third, internal equality within elderly group was the most important factor in determining HI measured by the medical care cost. Finally, "within group" component of urban area explained .0535 amomg HI, ,1035 measured by medical care cost. This indicated that the urban poor's underutilization of medical care was very important factor in explaining its degree of equity. There was the poor's underutilization of medical care within the groups as female, the elderly, and urban areas. This significantly explained the equity of medical care costs.

This study was conducted to investigate the variation of cone, seed and germination characteristics among populations and among individuals within populations of Picea jezoensis(Siebold & Zuccarini) Carriere distributed in Korea. Cone collected from 25 trees in two natural populations(Mt. Jiri and Mt. Dokyu) and their thirteen cone and seed characteristics as well as three germination behaviors were analyzed. Statistical analysis showed significant differences among populations and among individuals within populations in 9 traits except for seed breadth, seed weight, index of seed wing and mean germination time. Generally, morphological variation of cone and seed wings from Mt. Jiri population has smaller and longer than those of Mt. Dokyu population. Percentage of sound seeds and Tetrazolium test from Mt. Jiri population showed 1.79 and 1.87 higher values than Mt. Dokyu population, respectively. The maximum germination percentage was obtained at the optimum temperature of $20^{\circ}C$ and in this case, mean germination time and germination rate showed 7.5 days and 2.9 ea./day, respectively. In seed germination behaviors, percentage(40.7%) and rate(0.90 ea./day) of germination in Mt. Jiri population were more higher and faster than those of Mt. Dokyu population(17.7%, 0.37 ea./day). According to correlation analysis, P. jezoensis populations with small restricted distribution may have been reduced because seed qualities were correlated with increased levels of inbreeding and disproportion flowering.
