Objectives : The purpose of this study was to investigate regional commitment index(RGI) of hospital in Korea, and the relationship RGI and hospital characteristics, such as foundation, region, size. Therefore, we are to suggest fundamental information to make and evaluate healthcare resource policy in hospital- and government-level. Methods : The 'Patient Survey 2002(administered by Ministry of Health and Social Welfare(MOHW)' was analyzed. We selected the patient data of the hospitals above 100 beds. Then, we calculated the RGI, number of same cases divided by all cases in each hospital. By using SPSS/win ver 14.0, statistical analysis such as t-test, ANOVA, correlational and regression analysis was carried out. Results : The results are as follows. 1. Overall mean and standard deviation of RGI were revealed as 0.805${\pm}$0.225 in inpatients, and 0.871${\pm}$0.184 in outpatient. The median of inpatients' and outpatients' RGI were 0.890 and 0.933. The RGI of inpatients of private hospitals were revealed significantly higher than that of the public(public: 0.727, private: 0.822). However, outpatients' RGI was not revealed as significantly different. 2. The RGI of general specialty hospitals were significantly lower than others, therefore we could think that more inpatients and outpatients of general specialty hospitals flowed in from others province or metropolitan cities than other hospital types. 3. The RGI of hospitals holding above 400 beds were significantly lower than others in inpatients and outpatients. 5. The RGI of hospitals were significantly different among sixteen province and metropolitan cities. The RGI inpatients of Gwangju and Daejon metropolitan city were lowest sub-group(0.659, 0.664), and the RGI inpatients of Jeju was revealed as highest, 0.979. 6. Available beds, total doctors, and total employees were negatively correlated with RGI of inpatients and outpatients. 7. The significant influencing factors to RGI of inpatients and outpatients were appeared samely such as available beds, wide healthcare region, hospital size, and foundation type. Conclusions : It is considered that RGI of hospital represent competitive power in healthcare market. Also, the competitive advantage and quality of hospital clustered by characteristics could made out by RGI. Therefore, the results of this study would be useful to develop and evaluate hospital policy of individual hospital or local government.

Most of the materials used in various industrial fields and also in our daily life are multi-component materials or composite materials, and it is well known that there are many cases where adhesion between the constituents within the bonded systems plays an important role. There are various types of performance evaluation tests for the bonded materials, among which tests for evaluating the bond performance under various conditions may be regarded as the most interesting ones for those engaged in work related to adhesion. I have studied on the mechanism of adhesion form the rheological standpoint with my colleagues, including some students from Korea, and I am very happy to be able to have a talk on some of our research works. In Japan, the so-called "adhesives" are usually classified into two categories;adhesives and pressure sensitive adhesives (PSA). Adhesives are the materials which solidify after bonding and are after used as the structural adhesives because the adhesive strength is comparatively strong. On the other hand, the pressure sensitive adhesives never solidify and are used as PSA tapes, labels or decals. About the adhesives, we have examined the dependence of adhesive strength(shear, tensile, peel) upon both temperature and rate of deformation, and found out some empirical rules which are applicable to most of the adhesive systems. We have also developed a simplified theory of adhesion, which is deseribed in terms of mechanical equivalent mode1 and a few failure criteria. Although some of the common rules can be accounted for according to this theory, it must be pointed out that a fracture mechanical approach ms inevitable especially in the region where the meehanical relaxation time of the adhesive is extremely large [W. W. Lim and H. Mizumachi]. About the pressure sensitive adhesives, we have studied on the PSA performance (peel, tack, holding power) as a function of both the viscoelastic properties and surface chemical properties of the materials, and found out some rules, and again we have developed a theory which deseribes the mechanism. And in addition, we have studied on the miscibility between linear polymers and oligomers, because PSA is generally manufactured by blending gums and tackifier resins. Many phase diagrams have been found and some of them have been analyzed on thermodynamic basis, and it became evident that the miscibility is a very important factor in PSA [H. J. Kin and H. Mizumachi]. In this presentation, I want to emphasize the fact that the adhesion performance is closely related to the structure/property of the adhesives.adhesives.

Effects of supplemental charcoal powder and vitamin A on physico-chemical properties in 24 Hanwoo steers were investigated. The Hanwoo steers were randomly assigned to one of the three dietary treatments : 1) Control (commercial feed) 2) T1 (commercial feed supplemented with 2% charcoal powder and 0.2% vitamin A) 3) T2 (commercial feed with 2% charcoal powder). Crude fat content of proximate chemical composition in longissimus muscle was increased at control but moisture of control was rather lower than that of treatment groups (p<0.05). The WHC (water holding capacity) in longissimus muscle was tended to increase in control and shear force was higher in T2 (p<0.05). However, effects of diets charcoal power and vitamin A on pH were not found (p>0.05). Tenderness and flavor of sensory evaluation was improved significantly in control with peculiar and savory taste of Hanwoo being more emphasized. But Juiciness were not difference by treatments. When Hanwoo steers were fed with dietary charcoal powder and vitamin A, the palmitoleic acid and linoleic acid contents were higher compared with that of control (p<0.05), but oleic acid was higher in control than others.

When sea tide and wave velocity change, the behavior of silt protectors underwater changes, and a hydraulic force exceeding the anchor wave force is applied. In this study, the movement mechanism of a silt protector has been analyzed using the mass-spring method. The initial position of the silt protector was in the Jindo area near Gwangpo Port (742-1, Gyupori, Chongdo-myeon, Jindo-gun, Jeonnam, Korea). The tension required to exceed the holding power of the anchor was 0.05 m/s at 318 sec., 0.15 m/s at 77 sec., 0.25 m/s at 43 sec., and 0.3 m/s at 37 sec.. As the anchor started to move from the sea floor and the tide speed increased to 0.01 m/s, anchor movement start time shortened by an average of 11.2 sec.. Compared with when tide was the only affecting factor, the silt protector and anchor were found to have moved 19.7 % at 0.1 m/s, 7.6 % at 0.15 m/s, 5.8 % at 0.2 m/s, 4.3 % at 0.25 m/s and 2.8 % at 0.3 m/s, showing an increase. When wave effect was added to the tide, anchor movement started when the flow rate was slow 7.6 % of the time. With a high flow velocity, anchor movement started without any significant difference less than 4.3 % of the time. When tide speed exceeded 0.13 m/s and the direction of the waves matched, the silt protector was not able to perform due to collisions with surrounding sea structures. When installing a silt protector, the fluid flow situation and the silt protector situation must be carefully analyzed using the mass-spring method to apply the result found in this study.

This study was conducted to evaluate the effect of trehalose on the rheological properties of bread flour dough. Farinographic and viscographic properties, pH, total titratable acidity (TTA), and fermentation power were analyzed for flour dough rheology. Flour dough containing trehalose showed greater water absorption capacity and longer development time. However the stability, degree of softening, and farinograph quality number (FQN) were lower for the trehalose-containing flour dough, however, these factors decreased with increasing amounts of trehalose. Trehalose did not affect the beginning of gelatinization temperature and maximum viscosity temperature of flour. The maximum viscosity was the lowest with 6% trehalose, the end of final holding period, breakdown and setback values decreased with increasing amounts of trehalose. Flour dough with 4% trehalose had the lowest pH value for 120 min fermentation at $30^{\circ}C$, and the highest TTA value. Addition of 4% and 6% trehalose showed larger fermentation volume of dough than the control. The results suggested that trehalose positively affected the rheological properties of flour dough such as bread volume, softness, and staling delay.

This article introduces Abe Mituie's activities related to Korean and Japanese Buddhism and two newly discovered materials. He worked as a brain of Japanese cultural rule over Joseon Korea while holding various positions such as the president of KyeongSung Il Bo, the vice president of Kokmin Newspaper and the director of Central Joseon Association. Abe was responsible for Enkak Temple, the head temple of Japanese Rinzai section, and was one of the layman followers of Syak Soen who worked for the spread of modern Japanese Buddhism to Europe and America. He was a respectful Buddhist layman so as to teach Zen Buddhism for young Buddhist monks in Japan. After he started to assume charge in the Kyeong Sung Il Bo, he was also very active in movements in relation to Joseon Buddhism to the extent that he was found to be deeply involved in Joseon Buddhism sections. On the other hand, he concluded Joseon culture to be 'devastated.' He asserted that it was necessary to develop spiritual culture and revive Buddhism in order to resolve the devastation in the Joseon. In addition, he thought that Joseon Buddhism was ruined due to the misgovernment of the Joseon Dynasty, but had its own as great tradition as Japanese Buddhism. Therefore, in his opinion, there was a need to do research on Joseon Buddhism and find some way out of the contemporary difficulties. In order to save the situation, he made efforts to protect and revive Joseon Buddhism while paying continuous visits to Joseon Buddhist temples, supporting the publication of Buddhist canons and proposing to have a regular meeting of 'The Invitation of 30 Head Temples.' From his visit to Youngju Temple and his consistent relationship with Kang Daeryeon, it can be assumed that he was involved in reorganizing power structure in Joseon Buddhism and establishing various institutions. He emphasized the strict adherence of individuals and communities to rules in his lecture for students at Jung Ang Hak Rim. It was a way to revive Joseon Buddhism by creating a new social image of Joseon Buddhism. He continued to work for the restoration of Joseon Buddhism even after he retired from Kyeong Sung Il Bo and returned to Japan. He introduced the originality of Joseon Buddhism history to Japan and sent Japanese monks to Korea in order to do research and contribute to exchange between Korean and Japanese Buddhism. All things taken together, it is evident that Abe Mitzihe regarded Joseon as backward or stagnant from a perspective of evolutionist or orientalist, and was a Japanese elite to believe that it was just for Japan to control Korea. However, he was different from other Japanese elites in that he did not considered Joseon Buddhism merely as the object of propagation. He thought that Joseon Buddhism possessed its own great tradition and culture, but was ruined because of the misadministration of the Joseon Royal House. Therefore, in his opinion, Joseon Buddhism should be recovered by means of some supports, and its revival would lead to the restoration of Joseon culture as a whole, which would be realized by Japanese rule over Korea and Japanese elites' generous assistance.

This study aimed at investigating the content and meaning of royal garden(宮苑) sightseeing event in Pyoam Gang, sehwang's "Hogayugeumwongi" As the research method, descriptive research method was used, which is to consider and interpret the content and meaning in the historical records. Research results are summarized as follows. 1. "Hogayugeumwongi", which recorded the event that the King personally guided and explained the palace to the vassals, is a very precious historical records in Korean landscape gardening cultural history. Such thing is unprecedented in Joseon Dynasty as well as China. 2. The person who recorded this event was famous for shi seo hwa samjeol in the time, and the point that he was Pyoam, who was appreciated as 'the head(總帥) of artistic and literary circles(藝苑)', adds more value to the future generations. 3. The characteristic of this sightseeing event was to praise the vassals' labor, who contributed to the completion of Kyujanggak, to establish King Jongjo's direct rule in the early period of seizure of power, and eojin(御眞) dosa(圖寫), etc., which expressed the King's dignity. Jongjo utilized Geumwon, a forbidden place in the palace, to give a special privilege to the vassals' effort, who took a great part in realizing his political ideal. 4. One of sightseeing lines toward the backyard of Changdeok Palace could be identified. Though the sightseeing lines toward the backyard were not fixed, however this might be the best sightseeing line which Jongjo intentionally chose to enjoy that day's flavor of autumn. 5. The characteristic of this event was informal and somewhat extemporary 'sightseeing'. Therefore, it is considered, that day's event was relatively private and free 'play(遊)', while 'sanghwaeojoyeon(賞花漁釣宴)', which Jongjo gave to the vassals middle after his reign, was a royal 'banquet', which prepared frames, such as event holding time and form, qualification for participation, e.g. flower viewing, fishing, writing poems, etc. This research has a significance that it considered the content and meaning in historical records including the front and the rear context that "Hogayugeumwongi" was written through the consideration of related historical materials. "Hogayugeumwongi" can be utilized as a material for storytelling with regard to royal garden sightseeing in future as a valuable cultural content, also, follow-up study on this is necessary.

This study was concentrated on the subject of chou formation and physicochemical characteristics on medium flour mixed with 0, 25, 50, 75, 100% of rice flour in order to clarify the possibility to substitute rice flour for wheat flour on chou preparation. The water holding capacity, swelling power, and maximum viscosity were higher in rice flour than those in medium flour but the initial pasting temperature was equal to 65$^{\circ}C$ in the two flour groups. The ratio of setback during cooling became 0.94 in the rice flour and 1.14 in the medium flour. So, the rice flour showed a slow tendency during gel formation as compared with the medium flour. The volumes of the rice choux were ranged from 80.0% to 89.0% according to the mixing ratio of medium flour as compared with that of the chou of wheat flour. But, the choux formation were increased as much as 108.8% out the paste added gelation of glutinous substance and 124.4% at the paste added Span20 of emulsifier compared to the non-addition treatment. The paste of rice flour added gelatin and Span20 showed better dispersion of components, especially, the small granules of lipid were fairly or plentifully dispersed in the paste added Span20 due to emulsifying activity. In sensory evaluation, the chou of l00% rice flour was inferior to that of medium flour on cavity-forming but the choux of wheat flour mixed with 25%, 50%, and 75% of rice flour were equal or superior to that of medium flour on all characteristics tested such as appearance, surface color, cavity-forming, chewiness, and taste. There were no significant differences on the cavity-forming expansion and taste between choux of rice flour and wheat flour Therefore, the results of this study made conclusion that rice flour would be substituted for wheat flour on the chou preparation.

This study was designed to investigate the feasibility of utilizing concentrates of sunmul(soybean curd whey), the waste by-product of soybean curd processing, as functional food ingredients. Sunmul was concentrated by nanofiltration fo11owing ultrafiltration and then freeze-dried. The oil adsorption capacity of the nanofiltraion(NF) powder(97.33g/100g) was similar to that of sunmul powder(94.17g/100g), but was lower than that of ISP(isolated soy protein). However, the water holding capacity of NF powder could not be determined because the NF powder completely dissolved in water. The protein solubilities of sunmul powder and ISP in distilled H$_{2}$O, 0.1M and 0.5M NaCl were lowest at pH 4.0 and increased at more acidic or alkaline conditions. However, the protein solubility of NF powder was at its minimum at pH 6.0 and increased at more acidic or alkaline conditions. Emulsifying activity indexes of NF powder in 4% and 6% solution were minimal at pH 4.0 and 6.0, respectively, which were 3 to 8 times lower than that of sunmul powder. The emulsion stability of 4% sunmul solution was lowest at pH 4.0, but that of NF powder was highest at pH 5.0 and decreased at more acidic or alkaline conditions at all concentrations of solution. The total free amino acid contents of protein in sunmul, and NF power were 99.07 and 2,110.10mg%, respectively, and NF powder exhibited especially high threonine content. Rapid viscosity analysis of dough with 1 to 5% added NF powder demonstrated that all of the peak and final viscosities decreased with increasing NF powder concentration compared to the control.
