The purpose of this study is to examine the leisure activities of housewives, to identify the factors that influence leisure activities, and to explore the factors contribute to their life satisfaction. So, this study analyses the effects of econo-demographic and socio-cultural variables and of leisure constraint factors on the leisure activities of housewives. And it deals with how these variables and the leisure activities influence life satisfaction of housewives. For these puoposes, 508 housewives residing in Seoul & Daegu were selected for interviews. For data analysis such statistical methods as ANOVA, t-test, Pearson's correlation, adn Multiple Regression Analysis can be summarised. The main findings of the research are as follows: 1. Leisure acivities are classified in Self-developmental, Home-oriented, Time-consuming, Social and Children-concerned types by the technique of factor analysis. The average particiation level was high in Time-consuming type, but low in Self-developmental type. 2. The participation level of leisure activities shows significant differences by selected variables: The Self-developmental type shows significant differences by housewife's education level, income, husband's occupation, role orientation, home management type and leisure constraints. And Children-concerned type was differed to number of family nember, number of children, age of housewife and age of housewife and age of the youngst child. 3. The preference level of leisure activities differ by housewife's education level, income, husband's occupation, home management type and leisure constraints in the Self-developmental and the Social type. And the preference level of Home-oriented leisure activities was high in the middle class of income and husband's occupation. 4. The preference and participation level of leisure activities show differences. And the variables affecting the differences were housewife's age, education level, home management type, role orientation, leisure constraint factors in the Self-developmental type, and were demographic variables such as number of family member, housewife's age in the Home-oriented type. 5. The variables which affected the level of life satisfaction independently were leisure space, income, the participation level of the Self-developmental and the Social type and the preference level of the Self-developmental type.

The development of the lobe pattern in the human dentition plays a part in the form and function of each individual teeth. In order to determin the morphological categories used to describe the occlusal surfaces of the maxillary and mandibular molars, the variation of the developmental grooves which separate each lobe in the molars was examined and analysed. The obtained conclusions were as follow. 1. Most of the maxillary first molars with more distinct and more developmental grooves than the other molars but in most cases of the third molar, a heart-shaped outline due to poorly developed or abscent distolingual cusp was most frequent and in this case the third molar had the 3 cusps separated by the central developmental groove and the buccal developmental groove. 2. In most cases, the mandibular first molar had the 5-cusp type that the groove patter resembles a Y, the second molar the 4-cusp type arranged in such a way that the buccal and lingual developmental grooves meet the central developmental groove at right angle on the occlusal surface and many instances of the mandibular third molars had the 5-cusp thpe with a+groove pattern which separatess the mesiolingual cusp from the distobuccal cusp and the 4-cusp type with a+groove pattern. 3. The maxillary and mandibular third molar were most variable in the developmental groove.

The purpose of this study is to explore the application structure of customized "lifelong education: (versus) higher education" for individuals with developmental disabilities in two types.As for the research method, expert consultation was composed secondary with literature analysis as the primary procedure.The contents of the study were presented by classifying the application structure of customized lifelong education versus higher education for individuals with developmental disabilities into two types. Accordingly, the first research content is a school type-centered structure, which can be understood as a type that focuses on higher education while linking aspects of lifelong education. And the second research content is a structure centered on the type of independent life of individuals with developmental disabilities, which can be understood as a type that focuses on lifelong education while linking with the aspects of higher education. As a result of the study, the aspect that the research contents considered above can be gradually realized through the currently established infrastructure at Daegu University in the current situation in Korea has been improved.

Purpose: This study examined the perceived quality of life of families of individuals with developmental disabilities who regularly participate in physical activities. It also explored differences in the quality of family life based on variables such as family relationships, family income, gender, disability type, and age. Methods: A survey was administered to 69 family members of individuals with developmental disabilities who regularly participate in physical activities. The collected data were analyzed using descriptive statistics, independent samples t-test, and one-way analysis of variance. Results: The average overall quality of life for families of individuals with developmental disabilities who participate in continuous physical activities was 3.49. After analyzing each subtype, psychological health was found to be 3.91, the burden for people with developmental disabilities was 2.75, community participation was 3.76, cohesion was 3.83, and openness was 3.49. No statistically significant differences were found in family relationships or family classes, disability type, age, or gender of the individuals with developmental disabilities across the variables. Conclusion: When planning service development and support to improve the quality of life for families of individuals with developmental disabilities, it is necessary to develop systematic programs at the family level rather than providing support based on various variables.

A gene (hpkA), encoding a histidine protein kinase homolog, has been identified in the upstream region of the espAB operon in Myxococcus xanthus. It encodes a 333 amino acid (35,952 Da) protein with a histidine protein kinase domain in the region from amino acid 90 to 317. Null mutations in the hpkA gene caused formation of loose irregular fruiting bodies, while wild-type strains developed tight hemispherical fruiting bodies under developmental conditions. Sporulation of the hpkA mutant was delayed by at least 12 h compared to that of the wild-type. It appeared that the hpkA mutation increased the expression of the espAB operon by more than 2-fold compared with the wild-type under developmental conditions. Expression of the hpkA gene was low under vegetative conditions, but was highly induced under developmental conditions.

This study aims to explore how the transformational leadership (consisting of three factors"charisma, individualized consideration, and intellectual stimulation) and the organizational culture (typified by developmental, rational, consensual, and hierarchical culture) are related to the organizational effectiveness (consisting of job satisfaction, organizational commitment, and intention to leave a job) of dental clinics. We found the following empirical results through a survey of 378 persons who work in dental clinics. Firstly, the respondents acknowledged charismatic leadership as the typical type of leadership ; as for organizational culture, a culture of consensus is recognized as the representative type. Secondly, transformational leadership has different effects according to the type of organizational culture: a positive influence in developmental and rational cultures, but a negative influence in consensual and hierarchical cultures. Thirdly, developmental culture has proven to be the most suitable for increasing job satisfaction and organizational commitment. The developmental, rational, and consensual cultures have all contributed to reducing intention to leave among clinic staff, whereas in the hierarchical culture, intention has been elevated. Fourthly, transformational leadership has a positive effect on the job satisfaction and organizational commitment; the intent to leave has been lessened under individualized consideration and charismatic leadership, but has been increased under leadership of intellectual stimulation. Fifthly, it is consideration and charisma that help to increase organizational effectiveness. These influences will become more effective through a developmental culture. Based on the above empirical results, we propose practical measures to improve the organizational effectiveness of clinics, in particular dental clinics. In order to build developmental culture, the doctor (manager) should produce an atmosphere in the clinic in which staff members are able to create and jointly own ideas and then promote awareness of staff participation. Additionally, in order to bring leadership of charisma and consideration into full play, the doctor should shape a relationship of mutual trust mainly by recognizing and praising the work of clinic staff. Finally, the doctor needs to acknowledge that organizational effectiveness can be significantly improved by increasing the transparency of the business.
