This study examined whether industry-level competition affects excess stock returns because of changes in cash holdings. Competitive inter-company threats increase the possibility of the manager's replacement, and function to induce management to make their best efforts, resulting in the amount and quality of the information provided by the enterprise increasing. Therefore, as competition intensifies, agency problems are reduced and stock returns increase because the company's cash holdings are expected to increase. However, there is a view that firms in industries with severe competition tend to have high information asymmetry because competitors may compete in more favorable positions by using detailed information disclosed by the competing firms. Accordingly, as market competition intensifies, the excess stock returns resulting from increased cash holdings are expected to decline. These results show that excess stock returns because of increases in cash holdings increase as the degree of competition in the industry intensifies, thus supporting the positive effect of market competition. Overall, the results of this study provide an understanding that market competition plays an effective external governance mechanism and that investors positively evaluate the cash held by companies with severe industry competition.

This thesis analyzes the effectiveness of master's transformational and transactional leadership on organizational commitment as well as job satisfaction of private security, scrutinizes the difference in master's leadership according to social-demographic group. The sum of this thesis is as follows. To begin with, analyzed the difference of leadership style according to social-demographic characteristics of private security, it showed that monthly income is over 2.5 million won as well as people over 30 years old have higher transformational leadership than the others. That is, the older people's age is and the more someone gains his living, the higher he esteems and trusts his master who has charisma, personal concern and shows intellectual stimulus. And examined thoroughly the difference of organizational commitment as well as job satisfaction in accordance with social-demographic characteristics of private security, people who are 20-25 years old, are college graduates and employees who have worked for 2-3 years do well calculational commitment. It means that the younger he is and the lower academic background is, the higher calculational commitment is by the profit and loss which affects them. Secondly, inquired into consequence of leadership style on job satisfaction. Leadership of intellectual stimulus has negative effect on job satisfaction, whereas it has positive effect on conditional compensation. Exactly, if the master exhibits leadership that stimulate to improve an initiative, it reduces the job satisfaction. On the contrary, for the reason that his master indicates leadership that accompanies conditional compensation, job satisfaction tends to increase. Finally, judged from the effects of leadership style on organizational commitment, the charisma, the lower factor of transformational leadership affects to emotional commitment positively and then, it shows that employees tend to become attached to the organization and have a sense of oneness with it, if their master is able to show charismatic leadership. In conclusion, the private security companies pursue employees whose school career and payment is lower because of incidence in labor expense related with the profit and loss. Owing to it, employees are not satisfied with their job much. And also there is the change in increasing rate of job satisfaction according to business performance of the conditional compensation, i.e. a consideration, a promotion, etc., and the calculational commitment. Therefore, the university should try to focus on the researches for cultivate more professional manpower for business, the companies must try to make better deal, offer welfare for their employees to develop of the private security industry, to rise the job satisfaction of private security. And then, investigation to find private security's own level ought to be done by organic industry-academic cooperation of university and industries.

This study was performed to investigate the performance state and improvement countermeasure of Primary Health care Posts(PHPs). The operation reports of PHPs(1996 330 PHPs, 1999 313 PHPs) located in Kyongsangbuk-Do and data collected by self-administered questionnaire survey of 280 community health practitioners(CHPs) were analyzed. The major results were as follows: Population per PHP in 1999 decreased in number compared with 1996. But population of the aged increased in number. The performance status of PHP in 1999 increased compared with 1996. A hundred forty one community health practitioners(50.4%) replied that the fiscal standing of PHP was good. Only 1.4% replied that the fiscal standing of PHP was difficult. For the degree of satisfaction in affairs, overall of community health practitioners felt proud. The degree of cooperation between PHP and public health institutions was high and the degree of cooperation of between PHP and private medical institutions was high. The degree of cooperation between PHP and Health Center was significantly different by age of CHP, the service period of CHP, and CHP's service period at present PHP. Over seventy percent of CHPs replied that they had cooperative relationship with operation council, village health workers, community organization. CHPs who drew up the paper on PHP's health activity plan were 96.4 % and only 11.4% of CHPs participated drawing up the report on the second community health plan. CHPs who grasped the blood pressure and smoking status of residents over 70% were 88.2%, 63.9% respectively and the grasp rate of blood pressure fur residents were significantly different according to age and educational level of CHP. CHPs received job education in addition continuous job education arid participated on research program in last 3 years were 27.5%, respectively. CHPs performed the return health program for residents in last 3years were 65.4%. Over 95% of CHPs replied that PHPs might be necessary and 53.9% of CHPs replied that the role of PHPs should be increased. CHPS indicated that major reasons of FHPs lockout were lack of understanding for PHP and administrative convenience, CHPs were officials in special government service governors intention of self-governing body. CHPs suggested number of population in health need such as the aged and patients with chronic disease, opinion of residents, population size, traffic situation and network in order as evaluation criteria for PHP and suggested results of health performance, degree of relationship with residents, results of medical examination anti treatment, ability for administration and affairs in order as evaluation criteria for CHP. CHPs replied that the important countermeasures for PHPs under standard were affairs improvement of PHPs and shifting of location to health weakness area in city. Over 50% of CHPs indicated that the most important thing for improvement of PHPs was affairs adjustment of CLIP. And CHPs suggested that health programs carried out in priority at PHP were management of diabetes mellitus and hypertention. home visiting health care, health care for the aged. The Affairs of BLIP should be adjusted to satisfy community health need and health programs such as management of diabetes mellitus and hypertention, home visiting health care, health care for the aged should be activated in order that PHPs become organization reflecting value system of primary health care.

In temperate zone planting rice at different date subjects the Crop to different climatic condition. The present study aimed at comparison of the change in source-sink relationship of the Japonica(J) and that of IndicaxJaponica(I$\times$J) type rice cultivars caused by shift of heading date. Two J- and two I$\times$J-type cultivars were made to head on August 16, August 26, and September 5. Sink capacity was changed by shift of heading date in different mode between the types of cultivars. In both types major determinant of sink capacity was number of effective tillers, and the number of spikelets per panicle was the minor. In J-type earlier planting/heading was beneficial to increased panicle numbers and this was due mainly to a larger diurnal difference in temperature. I$\times$J-type cultivars favored a higher daily mean temperature to increase the sink capacity. The ability of source at heading, in terms of leaf area per panicle, chlorophyll content per spiklet, photosynthetic ability of leaves per unit area at 25$\^{\circ}C$, carbohydrate and N contents of leaves, was not so different among different heading dates in both types. However, the source activity was governed principally by temperature during grain filling. The J-type cultivars headed on Sept. 5 and I$\times$J-type cultivars headed later than August 16 could not have had sufficient source activity in grain filling due to lower temperature.
