This study is an analysis of slope failure examples of cut sedimentary hills during construction road in Kyoungsang Basin, especially Yangsan Fault system (Ilkwang-Dongrae fault). This area involved a lot of hillslope failures compared to other areas during road construction. The exposed failure slopes were first face-mapped, and then back analyzed based on the limit equilibrium method to assess the shear strength parameters of discontinuity (bedding). The results of this analysis indicate that the shear strength parameters of discontinuity (bedding) are significantly smaller than those used in the design stage and presented in the existing works. The filling in the bedding and emerging groundwater may be decreasing strength parameters. Especially, the clay in the bedding plays a key role in the effect of the shear strength. The study also suggests that the bedding angle and the internal friction angle are proportional to each other. Using this relationship and knowing the bedding angle, the friction can easily be estimated.

The food used in the royal palace of Chosun dynasty(朝鮮王朝) are viewed from various aspects of the dishes for ordinary meal, royal banquet, reception for the foreign representatives, wedding feast, and ancestral rites. Unfortunately most of knowledge on the food used in the royal palace is not accurate as it had been delivered orally and includes only that of the late Chosun dynasty era. Accordingly more accurate knowledge on its historical change could be illustrated by the ancient literature, including uigue(full account, 儀軌), dungrok(memorandum, 膳錄) or balgi(list, 件記). Though it is different from the preparation of King´s dinner table in kitchen, the uigue on ordinary meal, while King Jungcho(正祖) and his troupe visited the Hwasung(華城) has been handed down as the literature on the ordinary meal of the royal palace. Twenty seven kinds of uigue and dungrok on royal banquet for a celebration, from the 45th year of Sook Jong(肅宗, 1715) to the 6th year of Kwang Moo(光武, 1902), remain & reveal the change of features on dishes and food materials for royal banquet. Twenty kinds of uigue and dungrok on foods for reception of Chinese representatives, from the first year of Kwang Hae Koon(光海君, 1609) to the 21st year of Injo(仁祖, 1643), remain and antedate those on foods for royal banquet approximately 100 years. These have been precious materials for historical view on foods used in the royal palace. Twenty kinds of dungrok and uigue of karaedogam(嘉禮都監), in which dishes, food materials, and table setting diagram for dongrae feast (同牢宴) were put on record, remain as the litherature of wedding feast. Wangchosilrok(dynastic record, 王朝實錄) and numerous kinds of uigue have been helpful for study on foods used in ancestral rites. Detailed kinds and cooking procedures of foods for ancestral rites were clearly explained in Taesangji(太常志). A full view on foods used in the royal palace will be reproduced only through analytic study of these ancient litheratures.

The purpose of this study is to deeply understand consumer characteristics of department stores in pusan to cope with intensive competition of distribution channels. To complete this purpose, literature study was done through secondary data, than statistical research was conducted from 23th April to 17th May, 2001, through interview with 600 consumers of Hyundai department store in Pusan. Consumers of department stores earn more money than average, and they purchase fashion goods rather than necessities at department stores. Thus to deal with discount store, department stores need to lay stress on prestigious image and fashion goods. And to deal with other competitive department stores, they have to develope more distinctive and superior marketing mix than counter part. These days distribution situations of pusan are changed owing to prohibition of shuttle bus, opening of second section of subway line 2, and opening of Lotte department store at Dongrae. Thus departments stores also have to investigate the change of shopping behavior of consumers.

Background : Willingness to satisfy patients(WSP) among nurses is essential to promoting patient satisfaction which is a critical component in the quality of health care and its outcomes. This study was carried out to empirically find out the affecting factors of WSP among nurses in hospital settings. Methods : The model contains seven job relating determinants and two intervening variables as follows: i) job relating variables of professional status, task requirements, pay, physician-nurse interaction, nurse-nurse interaction, organizational policies, and autonomy, ii) intervening variables of job satisfaction and organizational commitment. Data were collected from 205 nurses in two general hospitals owned by one foundation located in Pusan, Korea, using a structured and self-administered questionnaire. Results : The major results were as follows: First, the results of ANOVA on WPS by personal characteristics showed a statistically significant relationships between WPS and hierarchical orders(p<.01) ana tenure(p<.10). Comparing with the lower orders and shorter tenure, the higher orders and the longer tenure showed better WPS. Second, the results of simple correlation analysis between WPS and determinants and intervening variables showed the following variables, in order of importance, were statistically significant(p<.01): work satisfaction(+), organizational commitment(+), task requirements(+), nurse-interaction(+), professional status(+), physician-nurse interaction(+). Third, the results of path analysis showed that two intervening variables of job satisfaction and organizational commitment, and three determinants of task requirements, professional status, and nurse-nurse interaction had a positively significant direct effect to WPS. Conclusion : The results suggest that nurses who are more satisfied with task requirements, status, nurse-nurse interaction, overall job satisfaction, and organizational commitment, will behave in ways that patients find more satisfied.

We investigated the temperature effects on the virulence, development, reproduction, and otility of two Korean isolates of entomopathogenic nematodes, Steinernema glaseri Dongrae strain and S. longicaudum Nonsan strain. In addition, we studied the growth and virulence of their respective symbiotic bacterium, Xenorhabdus poinarii for S. glaseri and Xenorhabdus sp. for S. longicaudum, in an insect host at different temperatures. Insects infected with the nematode-bacterium complex or the symbiotic bacterium was placed at $13^{\circ}C,\;18^{\circ}C,\;24^{\circ}C,\;30^{\circ}C,\;or\;35^{\circ}C$ in the dark and the various parameters were monitored. Both nematode species caused mortality at all temperatures tested, with higher mortalities occurring at temperatures between $24^{\circ}C\;and\;30^{\circ}C$. However, S. longicaudum was better adapted to cold temperatures and caused higher mortality at $18^{\circ}C$ than S. glaseri. Both nematode species developed to adult at all temperatures, but no progeny production occurred at $13^{\circ}C\;or\;35^{\circ}C$. For S. glaseri, nematode progeny production was best at inocula levels above 20 infective juveniles/host at $24^{\circ}C\;and\;30^{\circ}C$, but for S. longicaudum, progeny production was generally better at $24^{\circ}C$. Steinernema glaseri showed the greatest motility at $30^{\circ}C$, whereas S. longicaudum showed good motility at $24^{\circ}C\;and\;30^{\circ}C$. Both bacterial species grew at all tested temperatures, but Xenorhabdus sp. was more virulent at low temperatures $(13^{\circ}C\;and\;18^{\circ}C)$ than X. poinarii.

The plant parasitic nematodes were surveyed from Zoysia matrella, Agrotis palustris, and Poa pratensis at Anyang Benest Golf Club, Dongrae Benest Golf Club, and Gapyeong Benest Golf Club and from A. palustris at Castle Pine Golf Club. Criconema sp., Ditylenchus sp., Helicotylenchus sp., Meloidogyine sp., Pratylenchus sp., Tylenchus sp., and Tylenchorhynechus sp. were separated from unhealthy turf areas. In addition, Tylenchorhynechus dubius was firstly recorded from A. palustris at the green of Castle Pine Golf Club. Meloidogyne sp., Helicotylenchus sp., Ditylenchus sp., and Pratylenohus were separated from Z. matrella, Meloidogyne sp. and Pratylenchus were from A. palustris, and Meloidogyne sp., Tylenchus sp., Tylenchorhynchus sp., Criconema sp., and Helicotylenchus sp. were from P. pratensis. Out of separated nematodes, Meloidogyne was the most serious nematode and widely distributed.

The purpose of this study is to prepare the way for the prevention and improvement of the ocean environment pollution and destruction by researching and analyzing the degree of interests in the ocean environment which the students of seaside vocational high schools have. The concerns of this study are as follows: 1. The vocational high school students in the seaside cities of Busan and Pohang have recognized that the ocean is the object of the highest potential of development and that through the degree of their recognition that they should better preserve the ocean environment prior to a high degree of local seaside development. 2. Although they have recognized that the ocean environment has a great influence on the life of people, their interests in the environment is low. Also, it is shown that they get their knowledge and information through TV. 3. They've understood that the main factor of ocean contamination concerns the home and the causes of ocean contamination are sewage and waste material from daily life. Moreover, their answers reveal that they believe that they should participate in a sanitization activity for the ocean environment voluntarily and put trash into nearby trash cans as opposed to inconsiderately throwing away trash on the beach. 4. Their answers also show that they recognize the elements that can best preserve the ocean environment start at home and with government, and school services through experience activities are the most effective for the education of the ocean environment.

This study is about the armors that high navy officers of Joseon wore during the period of Japanese invasion of Korea(1592~1598). The kinds of armors that these officers wore during this period are Sueungap, cheolgap, pigap, jigap and myeongap. Sueungap, cheolgap, pigap are all described in literatures, which were released in that period and the early Joseon period. According to publications that were released during that period, Yuyeopgap was a type of an iron armor. Armors that are recorded in only literatures published in the early Joseon period include swaejagap, gyeongbeongap, dujeonggap, hwangdongdujeonggap and dudumigap. Myeongap is found only in publications that were made in the above war time. The styles of armors are largely classified into chalgap and dujeonggap. The chalgap-styled armors used gapchal as their main component. Dujeonggap-styled armors used fabrics and dujeong. The names and the manufacturing methods of the gapchal did not changed since its creation in the early Joseon period until the above wartime. But, their shapes were considerably changed between the two times. This is clearly shown in armors that were found in the moat of the Dongrae-eup fortress. Dujeonggap-styled armors that were used during the period of the Japan-Korea war were a successor to those of dujeonggap-styled armors of the early Joseon period. But the former armors were different from the latter in that they had no gapchal inside. They are well represented by Jeong Chung Sin's armor.

The oriental beetle, Exomala orientalis, Is the most important insect pest of turfgrass in Korean golf courses. The study was carried out to get practical information on the sampling of E. orientalis in golf courses. Real numbers of E. orientalis larvae were compared with and observed numbers depending on sampling size (5$\times$5 cm, l0$\times$10 cm, 20$\times$20 cm, 30$\times$30 cm, and 40$\times$40 cm) and times (3 to 15 replicates) in Dongrae Benest Golf Club. Over 95% accuracy was obtained between real data and estimated data at the density of over 303 larvae/m$^2$ when the 20$\times$20 cm was sampled with 4 replications. Larval density of E. orientalis was different depending on year and course sites (tee, fairway, rough, green).

The purpose of this study is to examine the effect of small group inquiry activities using IIM on the science process skills and scientific attitudes of students in higher elementary grades. To verify research problems, the subjects of this study were fifth-grade students selected from two classes of an elementary school located in Busan : the research group was composed of thirty students who participated in small group inquiry activities using IIM teaching model situation, and the other was composed of thirty students(comparative group) who participated in a teacher map- based learning situation. For six weeks, the small group inquiry activities using IIM were executed in the research group, while the teacher-map based instruction was conducted in the comparative group Test showed the following results: First, the research group showed a significant improvement in their science process skills compared to the comparative group. Second, the research group did not show a significant improvement in their scientific attitudes compared to the comparative group. In conclusion, small group inquiry activities using the IIM teaching model was more effective than the teacher map-based teaching model on science process skills. However, since the study has a limit on the object of the study and the applied curriculum, the additional studies need to be conducted with an extended comparative group and curriculum.
