Present study investigated the relationship between children's psychiatric disorders and their mothers' psychological problems. Ninety-one psychiatric outpatients from a children's hospital were classified into three diagnostic groups - internalizing symptom group(n=35), externalizing symptom group(n=35), and developmental disorder group(n=21) - based on their psychiatric problems. A normal control group was formed by matching on the age and education of mothers. Mothers' MMPI profiles which were classified into five types - normal, depression, anxiety disorder, somatization disorder, and personality disorder - were examined in relation with children's diagnoses. The profiles of the mothers in the normal control group were mostly normal, while depressive profiles were dominant among those of the clinical groups regardless of the children's diagnoses. Therefore, the data implied association between children's psychiatric problems and their mothers' psychological problems. A possibility of negative reciprocal interactions between children and their mothers was discussed. It was also suggested that further research need to examine the specific effects of children's psychiatric problems on the psychological adjustment of their mothers, as well as the effects of parental psychiatric problems on the adjustment of their offsprings.

본 연구는 우려나라 기업집단(企業集團)의 비용함수분석(費用函數分析)을 통해 제조업과 금융업간의 기술적 생산조건을 규명함으로써 제조산업(製造産業)과 금융업겸영(金融業兼營)의 효율성여부를 분석하고, 앞으로의 바람직한 금융소유지배규제정책방향(金融所有支配規制政策方向)을 모색하고 있다. 기업집단의 비용함수분석결과에 의하면 비금융제조업(非金融製造業)과 증권업(證卷業)간에는 범위(範圍)의 경제(經濟)(상호효율증진효과(相互效率增進效果))가 있는 반면 제조업(製造業)과 은행업(銀行業)이나 기타금융업과(其他金融業)의 사이에는 그런 관계가 부재(不在)하며, 우리나라 기업집단(企業集團)들은 평균적으로 규모가 과대하여 비효율(非效率)을 초래하고 있는 것으로 관찰되고 있다. 앞으로 우리 경제(經濟)의 개방화(開放化)와 금융자율화(金融自律化) 그리고 세계경제(世界經濟)의 통합화(統合化)가 진전됨에 따라서 제조업(製造業)과 증권업(證卷業)의 겸영(兼營)및 소유지배관계(所有支配關係)는 지속강화(持續强化)되겠지만 제조업(製造業)과 은행업(銀行業)과의 관계는 오히려 그 연계(連繫)가 약화(弱化)되며, 기업집단(企業集團)의 평균규모도 축소조정(縮小調整)될 것으로 전망된다. 이에 따라 장기적으로 금융소유규제정책(金融所有規制政策)은, 우선은 은행업과 제조업간의 소유지배를 허용하든 금지하든 어느 경우나 뚜렷한 자원배분(資源配分)의 왜곡(歪曲)이나 효율증진효과(效率增進效果)가 나타나지는 않기 때문에, 정부가 특정 소유구조를 강제하기보다는 은행(銀行)이나 기업(企業)들이 자체판단(自體判斷)에 의해 최적소유구조(最適所有構造)를 결정(決定)하도록 하되, 특정 소유지배관계(所有支配關係)의 형성이 금융산업 및 경제내에 경쟁저해적(競爭沮害的) 효과(效果)를 초래하지 않도록 하는 경쟁정책적(競爭政策的)차원에서 접근(接近)하는 것이 바람직할 것으로 판단된다. 그리고 소유집중(所有集中)에 따른 은행(銀行)의 안전(安全) 건전성(健全性) 저해효과(沮害效果)를 방지하기 위해서는 동일인(同一人) 여신한도(與信限度)의 엄격한 운용(運用) 등 건전감독기능(健全監督機能)을 보강해야 할 것이다.

The purpose of this study was to investigate the relationship between the differences in the acoustic measurements (AVQI) and the auditory-perceptual assessments (GRBAS, CAPE-V) of the normal and vocal fold nodules. For this purpose, Total 335 voice samples were analyzed acoustically and three raters performed auditory-perceptual assessments. in the results, AVQI, G, and OS scores of the normal group were lower than those of the vocal fold nodules group. The correlations between the G scale and the OS scale were highly correlated, and the correlation between the AVQI, and auditory-perceptual results (G and OS) was also high value. The threshold values for discriminating AVQI, G, and OS between the two groups were ${\leq}4.06$, ${\leq}1$, and ${\leq}26$, respectively, and the predictive diagnostic power was 0.840, 0.860, and 0.848. In conclusion, AVQI and auditory-perceptual evaluation can improve potentiality the screening of vocal fold nodules and help to determine the diagnosis and treatment plan of voice disorders.

This study was conducted to examine genetic variation on leaf characteristics of Machilus thunbergii populations. Ten populations were subjected to multivariate analysis for 9 characteristics of leaf morphology. Average length of leaf blade, leaf width, petiole length, vein number were 9.8cm, 4.0cm, 1.8cm, 8.4 respectively, while angle of leaf base and leaf apex were $67.9^{\circ}$ and $78^{\circ}$ respectively. The coefficient of variation (C.V.) on leaf characteristics was 20% which indicate similar features among the populations. Nested analysis showed statistically signigicant differences among populations as well as among individuals within populations. Genetic relationship between populations using complete linkage method showed four groups to Euclidean distance 1.2 and did not show a tendency to cluster into the same group. There were three principal components that had a meaningful eigenvalue over 1.0 among the 9 components. The explanatory power of the top three main components on the total variation was 92.8%. The first principal component (PC) was explained about 40.3% which is mainly correlated with maximum leaf width and the second PC was explained about 28.7% which is correlated with leaf blade length. The third PC was explained about 23.8% which is correlated with petiole length ($X_3$). These characters were important factors for analysis of the relationship among natural populations of M. thunbergii.

The purpose of this study is to analyze the process of relationships among participants in a group mentoring program. Sixteen youths who participated as mentees in a group mentoring program were theoretically sampled and participated in in-depth interviews. The analysis was based on Strauss and Corbin's grounded theory approach(1990). The result shows that the qualitative text data were classified into 14 categories and 31 sub-categories. Four different types of mentees' experiences were identified: 'expanded mentoring relationship', 'peer-oriented relationship', 'task-oriented relationship' and 'avoidant relationship'. Through a process analysis, four stages including 'stage of exploring', 'stage of establishing relations', 'stage of conflict' and 'stage of expanding relations' were discovered. Implications for social work intervention and policy development were discussed based on these findings.

This study was conducted to investigate the variation of fruit and seed morphology among populations and among individuals within population of Sorbus commixta Hedl. distributed in Korea. Fruits collected from 42 trees in six natural populations and their six fruit and four seed characteristics were analyzed. In all characteristics, there were significant differences among populations and among individuals within populations. Especially, number of fruits per fruit-bearing branch and number of seeds per fruit showed higher values among populations in total variance component. Coefficients of variation in the number of fruits per fruit-bearing branch and seed weight are relatively high (42.0~75.3%) compared to other traits (11.9~32.1%). As a result of simple correlation analysis, the number of fruits per fruit-bearing branch showed a significant positive correlation with latitude but showed a negative correlation with longitude. According to cluster analysis, geographically close populations showed the tendency of clustering into the same group. Three principal components (PC) were deduced from principal component analysis, which explain the 87% of total variance of fruit and seed characteristics. The highest contribution was seed length and seed weight in PC1, fruit width and seed index in PC2 and fruit length and number of fruits per fruit-bearing branch in PC3.

This study examined the communication and conflict between ship prganization and ship management team. Those are measured and analyzed about both groups, and then the relationships would be investigated objectively and synthetically. Especially, this relationships are enlightened by measuring the level and gap of the communication and group conflict between ship organization and ship management team. The effect of that conflict is analyzed on the organization commitment and job satisfaction of ship organizations. As a result, this study demonstrates the communications have a negative influence on group conflict with statistic significance, also the conflicts effect negatively on the organization commitment and job satisfaction. In the analysis of gaps about the communication and conflict between groups, the level of group conflict is lowest in the group whose gap of communication is small and both communications are activated, and the organization commitment and job satisfaction are highest in the group whose gap of group conflicts is small and both level of the conflicts are low. To conclude, the ship organization and ship management teams in the shipping company have to lessen their conflict each other and heighten the organization commitment and job satisfaction through their smooth communication.
