Recombinant human pBrathyriod hormone related peptide (1-341 (rhPTHrP) has been known to stimulate bone resorption in intact bone tissue culture system. Osteoclast has been known as a primary responsible cell for bone resorption. To examine the effect of rhPTHrP on this cell, we employed disaggregated rat osteodast culture. As a result, we found that rhPTHrP sisnificBntly elevates both the number and total area of resorbed pits in this culture. On the other hand, the conflicting results between disagsregated rat osteoc13st culture and Ca2+-deficient hen osteoclast culture system have been a big obstacle for the progress of bone research. To verify the differences between rat 3nd chick osteoclast system, we performed the same experiment using chick embryonic osteoclast. Since the similar results were obtained from the disaggregated chick osteoclast culture, the discrepancy between chick and rat osteoclast culture study seemed to be due to the difference in culture method, rather due to the species-difference.

Nursing organization culture is common patterns of believing, thinking and behaving resulted from a variety of experiences and interaction nurses in the same setting. This study was performed based on the assumption of existence of different subcultures within meta-culture, to identify the differences of subculture among 5 nursing units and to analyze the relationship between nursing organization culture and organizational commitment In this study, two kinds of instruments were used. One was the instrument of nursing organization culture developed by researcher through literature review and interview with nurses. The other one was Mowday's Organizational Commitment Questionnaire to measure organizational commitment of nurses. Both of them were structured with 5 scale. The answers were analyzed using SPSS program. The results were as follows : The meta-culture of the nursing organization culture was the people stable culture. There were significant differences in people development culture and people stable culture among 5 nursing units and all 5 units had different culture score. Especially, emergency room had strong development culture, and stable culture was dominant in operating room. Other units except emergency room and operating room had high scores in people stable culture than other culture types, but revealed different distribution. There were significant differences of the nursing organizational culture types -people development, task development, people stable, task stable-among 5 units. Four types of nursing organizational culture consisted of competing values in one organization. Nurses's organizational commitments were sign ificantly different among the units. The score per ceived by nurses who work in emergency room, operating room and leu was higher commitment score than that of medical/surgical nursing units Nurse's commitment to nursing organization was also related to total work period as nurse in any setting and work period in this hospital. Organizational commitment was significantly different among the nursing culture types, indicating that the scores of developmental culture were higher than stable culture. In conclusion, there were many different subcultures in nursing organization. In subculture, the organizational commitment was different. Therefore, the change of nursing organization culture or nursing unit culture needs to be considered to hire, give orientation, teach. and reallocate nurses efficiently. Research on nursing organization culture using both qualitative and quantitative method needs to be further considered. Furthermore, the strategy in nursing organization culture for nursing administrator to manage human resources efficiently and to change nursing unit effectively, needs to be developed.

The purpose of this paper is to investigate the user distribution and the accessibilities, and the factors restricting the use of House of Culture, Gwua-Chun city, and to discuss and propose an improved management for House of Culture. The survey and analyses in this paper have showed some considerable aspects of House of Culture. Smaller culture facilities are more effective with respects to the programs and the use of rooms. Most of users of the facilities are housewives and retired old people because those who have jobs can not use in the daytime when the facilities are open. Many cases of House of Culture are parts of village offices, libraries, and culture centers. The rooms are very efficiently composed. Users of House of Culture want larger space facilities and lecture programs for health and sports.

Modern cities are weak in traditional culture with the lack of characteristics and the problem of environmental deterioration. As the important carrier of urban culture, landscape architecture should be responsible for solving these problems. The urban need is paid much attention in the design of South Bank Linear Park in Meizhou city. Following the principle of inheriting and developing urban traditional culture, the design of the whole park is integrated with Hakka culture in Meizhou, which forms the landscape with local features and modern landscape architecture culture, and promotes the urban culture construction.

Culture speaks for the characters of the period, so it is presented by the mutual actions of many factors affecting culture. Foreign culture, introduced by cultural exchange, was modified and accepted into a new form and value system. In the beginning, only foreigners danced these dances, but Chinese started to dance them gradually. Thus, the dancing costume showed the complete fusion of Chinese and exotic styles. Especially, in the Tang dynasty, Chinese accepted foreign culture very actively and with open hearts. They accepted foreign culture based on their traditional culture, and fused them completely. In these costumes, not one culture was prominent, but many cultures from Gandhara to East and West Turkistan and even to Persian and Hellenism were synthesized together. Chinese, in the Tang dynasty, retained on their traditional culture and modified new foreign culture into Chinese style.

Organizational culture has been, by and large, regarded as one of the most significant factors to manage organizations. Especially the understanding of empowerment is pivotal, leading to explain organizational cultures. For hospital workers whose services are closely related to quality and performance of their hospitals, empowerment is now called upon more than ever before. This study is intended to investigate the relationship between organizational culture types and hospital workers' empowerment levels. The data were collected from 589 hospital workers at one university hospital and two general hospitals using the self reported questionnaire from Jan.9 to Jan.20 in 2004. The findings were as follows: 1. Empowerment levels were significantly different among the four organizational culture types. Developmental culture group showed the highest empowerment score(3.74), and next were group culture(3.64), rational culture(3.62), and hierarchial culture(3.46). 2. There was a significantly positive correlation between group culture and empowerment(r=.298, p<.000), between developmental culture and empowerment(r=.295, p<.000). But there was not a significantly correlation between hierarchial culture, and between rational culture. 3. According to the multiple regression analysis, self-esteem(${\beta}$=.417, p<.001), position (${\beta}$=-.190, p<.001), self-control(${\beta}$=.185, p<.001), and age(${\beta}$=.169, p<.01) were significant among general properties for organizational empowerment. As for organizational cultures, developmental culture(${\beta}$=.165, p<.001), group culture(${\beta}$=.099, p<.01), and rational culture (${\beta}$=.063, p<.05) were significant other than hierarchial culture. In conclusion, it is necessary to promote group culture and developmental culture to enhance hospital worker's empowerment level, and this article elucidates that understanding the organizational culture embedded in each organization is important for efficient management of organization.

This study was carried out to establish improved techniques on organogenesis from callus culture of Gladiolus. Organogenesis from the callus was effective in the half strength of MS solid medium without 2,4-D at 15 $^{\circ}C$ under 24 hours of daylength. Formation of adventitious root was most effective in the liquid shaking culture, and adventitious shoot induction was effective in the liquid stationary culture. From these results, we could find optimal culture conditions for redifferentiation from callus, in addition, liquid shaking culture revealed as more useful when compared with that of solid culture method for the redifferentiation of callus in Gladiolus `Topaz'.

Due to recent increased air traffic,, air traffic controllers in charge of en-route and approach control have faced huge increase in both workload and its intensity. The purpose of this paper is to analyze how much safety culture of air traffic controllers has effect on their complexity mitigation strategies during their duties. It could be expected complexity mitigation improve air traffic flow resulting in enhancing safety eventually. According to empirical analysis against air traffic controllers in civil aviation and air force in South Korea, it was proven safety culture had a statistically positive effect on complex mitigation strategies through safety behavior. In safety culture among air traffic controllers, intrinsic culture had a positive effect on extrinsic value of safety culture. Intrinsic value of safety culture led to air traffic controllers' safety behavior which created work complexity mitigation strategies. Among work complexity mitigation strategies, communication and cooperation was proven to be the most important factor effected by safety culture and behavior. It was implied that enhancing the intrinsic values of safety culture would cause to improve extrinsic safety culture and air traffic controller's work efficiency.

It was investigated whether culture filtrates produced by X. fastiduosa could be used to determine varietal susceptibility in grape cultivars to anthracnose as a substitute for pathogen inoculation or field screening. Bioassay of grape leaves with culture filtrates showed that their phytotoxicities were active and host-selective. Ethyl acetate extracts from those also showed the toxicities and host selectivity among grape cultivars. The sensitive range of plants to culture filtrates and their ethyl acetate extracts was consistent with the host range to the pathogen. Susceptible cultivars were sensitive to even highly diluted culture filtrates but resistant cultivars were not affected even at original culture filtrates. Susceptible cultivars were sensitive to the undiluted culture filtrates than highly diluted culture filtrates and the younger leaves were the more sensitive to the culture filtrates and their ethyl acetate extracts in grapes.
