Casts of 180 Korean male and female with normal occulsion of early permanent dentition (from dental age of Hellman III C, to IV A) were studied to measure the mesiodistal crown diameters and to calculate the coefficients of correlation between the teeth. From the study, the following conclusions were made: 1. Mesiodistal dimension of maxillary central incisors, canines, first molars and mandibular canines, first premolars, second premolars and first molars of male are larger than that of female. 2. Korean teeth are roughly intermediate between those of American Caucasian and those of American Negro. 3. In both sexes, the relation between the first and second premolars appeared highly correlated not only in the maxillary arch but also in the mandibular arch, and the relation between the central incisor and lateral incisor appeared highly correlated in the mandibular arch. 4. The relation between the maxillary and mandibular first premolars appeared highly correlated in both sex, and the relation between the maxillary canine and mandibular canine in male as well as between the maxillary central incisor and mandibular central incisor in female appeared highly correlated.

Subspecific difference of the percentage of white immature kernels (WIK) between japonica and indica rice cultivars was analyzed in relation to ripening temperature and yield characters. Thirty-three Chinese and 10 Japanese rice cultivars, including 32 japonica and 11 indica, were cultivated with three different cropping seasons for three years. The results were as follows: (1) Indica had less number of panicles, larger number of spikelets per panicle with higher yield, and longer and narrower kernels than japonica. In japonica, Chinese cultivars had less number of panicles and larger number of spikelets per panicle than Japanese cultivars. In addition, WIK was significantly higher in Chinese cultivars than in Japanese cultivars, because of the higher percentage of milky white kernels, even at similar temperature conditions during ripening. On the other hand, WIK in indica was not significantly different between the production areas and between the cropping seasons. (2) Regardless of subspecies, WIK in a large number of Chinese cultivars increased with increasing temperature during ripening within 20 days after heading, while this relation was uncommon in Japanese cultivars, showing the low temperature response. However, some Chinese cultivars had the low WIK with the low temperature response. (3) WIK in japonicawas positively correlated with 1000-kernel weight, spikelet density, kernel width and thickness, but negatively correlated with panicle length and grain filling percentage, while in indica it was positively correlated with panicle number per area, grain filling percentage, brown rice yield and kernel width, but negatively correlated with kernel length. These results indicated that WIK in both subspecies had a close relation to kernel size, and that WIK was high in japonica cultivars with wide and thick kernels and in indica cultivars with short and wide kernels.

The purpose of this study was to identify job satisfaction and organizational commitment depends on their organizational cultures. A survey, including the Organizational Culture Scale, Job Satisfaction Scale and Organizational Commitment Scale, was administered to 276 nurses working at 4 small to medium sized hospitals in B city. The dominant organizational culture of nursing organization was relation-oriented culture. The mean score of job satisfaction and organizational commitment was 2.68 and 4.25 respectively. Job satisfaction and organizational commitment were positively correlated with innovation-oriented, task-oriented and relation-oriented culture. Organizational commitment was negatively correlated with rank-oriented culture. Innovation-oriented, clinical career, relation-oriented and rank-oriented culture were variables influencing on job satisfaction and innovation-oriented and rank-oriented culture were major variables influencing organizational commitment. In conclusion, innovation-oriented and rank-oriented culture had a significant influence on nurses' job satisfaction and organizational commitment. Therefore, we have to develop strategies to enhancing the innovation-oriented culture and to reducing the rank-oriented culture.

In order to investigate the relation between weather factors, soil water, and tobacco yield grown by nonnulching and mulehing cultivations, a regression analysis was conducted for data collected from 8 years (1971 to 1978) for a flue-cured variety of Hicks. The soil water was calculated by Smith's method. 1 . Tobacco yield was largely correlated to soil water deficit during draught time for nonmulclung cultivation; $Y=6.146+8.6185\times-0.0925$\times2(R=0.935)^{***})$ 2. Tobacco yield was more largely correlated to soil water in flexible draght time interval than in fixed time interval during maximum growing phase.3. This field test was supposed that the optimal soil water condition was 65%field caps city. In this condition tobacco yield was 197. 1-216.5kg/10a for non-mulching cultivation. But the soil water deficit in draught season was little matter for mulching cultivation. The relation between xield and evaporation during May to June was Y: -1199.55+9.4 353$\times$:O. 0155$\times$2 (R=0.904") Maximum tobacco yield was expected to 223.6-251.4kg/10a for mulching cultivation. 5 . Tobacco required high temperature and light even in drying season (maximum growing phase) for mulching cultivation.tion.

This study examined the relation between mother-child verbal interaction strategies and children's narrative competence. Forty-eight 4-year-old middle class children(25 girls and 23 boys) and their mothers were observed in their homes. All the children were asked to produce a new story. Mothers used more descriptive statements and questions, more inferential questions and more evaluative questions than children. Children gave more answers and used more negative feedback than mothers. Mother's use of high-mental demanded question and positive feedback strategies were positively correlated with children's level of narrative structure. Mothers' use of inferential and evaluative questions were positively correlated with narrative length. Children's use of high-mental demanded statements and positive feedback strategies were positively correlated with their level of narrative structure and their use of descriptive and high-mental demanded strategies were positively correlated with narrative length.

Objectives : This study was to investigate the level of organizational culture and self-leadership on organizational effectiveness and the significant factors influencing organizational effectiveness in oral health professional. Methods : Data were obtained from a cross-sectional survey of 297 oral health professional(mean age=$29.95{\pm}8.10$). Participants in the study were recruited when they attended the dental health form in Gwangju. Organizational culture was classified into four factors: relation-oriented, innovation-oriented, hierarchy-oriented, task-oriented culture. Self-readership consisted of five factors: rehearsal/self-observation, self-goal establishment, self-esteem, self-criticism, self-reward. Organizational effectiveness included organizational commitment and job satisfaction. The data was analysed using t-test, one-way ANOVA, Pearson correlation and multiple regression. Results : The dominant organizational culture was rank-oriented culture. The mean score of self-readership score was 3.51 out of a maximum 5 points. Organizational commitment was positively correlated with age, relation-oriented culture, self-goal establishment, self-reward explained 41.9% and job satisfaction was positively correlated with relation-oriented culture and self-esteem explained 48.6%. Conclusions : Based on the findings, the organizational culture and self-readership was correlated with organizational effectiveness. These results suggest that further development should be continued to develop the effective self-readership and organizational culture to improve the organizational effectiveness of oral healthcare professional.
