Degummed silk from Bombyx mori was dissolved in 9.3M lithium bromide solution. The regenerated silk fibroin films were completely ${\alpha}$-randomcoil type as shown by x-ray diffraction and infrared spectroscopy. The structural changes in silk fibroin induced by immersion into methanol and dilute hydrochloric acid and its photo-yellowing effect was studied. The changes of crystallinity were measured by infrared spectrometer. Yellowness index caused by ultraviolet irradiation were observed as a function of the structural change on silk fibroin. On treatment with methanol, ${\alpha}$-randomcoil silk film is converted to the ${\beta}$-form structure. After the treatment of hydrochloric acid on ${\beta}$-form structure in silk induced by immersion into methanol, ${\beta}$-form in silk fibroin is partially decreased. Crystallization owing to ${\beta}$-form transition reduced the initial yellowness index by ultraviolet irradiation. A little ${\beta}$-form structure in silk fibroin increased the initial yellowness in comparison with more ${\beta}$-form structure.

A novel index representing burden distribution form in the blast furnace is developed and index estimation model is built with an empirical modeling method to monitor inner condition of the furnace without expensive sensors. To find the best combination of index and modeling method, two candidates for the index and four modeling methods have been examined. Results have shown that 3-D index have more resolution in describing the distribution form than 1-D index and ANN model produces smallest RMSE due to nonlinearity between the indices and charging mode. Although ANN has shown the best prediction accuracy in this study, PLS can be a good alternative due to its advantages in generalization capability, consistency, simplicity and training time. The second best result of PLS in the prediction results supports this fact.

The current study aims at the design of GIS-based systematic and quantitative standards for development available land forms, precluding any planners' subjective manipulation of those irregular lands. More specifically, first, as the elements of land form standards, both LFI (Land Form Index) and ARCI (Adjusted Related Circumscribing Circle Index) are proposed. Second, through the sample survey of ready-developed residential areas, standard minimum and maximum values for LFI and ARCI were extracted. Third, through the application of those standardized ranges of LFI and ARCI values, actual land form standardization process was performed for the lands with LFI and ARCI indices, falling below the range of standardized values. The significance of the current study lies within the objective proof of the possibility of GIS-supported land form standards applications to actual cases, through the introduction of LFI and ARCI as land form standard indices.

Objectives : The purpose of this study is to report a therapeutic effects of a Korean herbal prescription for antibiotics-associated diarrhea. Methods : Modified Hyangsayukgunja-tang was prescribed once or twice a day to a antibiotics-associated diarrhea patient. To observe the therapeutic effects, the frequency of defecation was counted and Bristol Stool Form Index was used. Laboratory tests were conducted periodically. Results : The frequency of defecation was decreased from 9 times a day to once a day. According to Bristol Stool Form Index, stool form was improved from Type 7 to Type 5. The level of red blood cell, hemoglobin and albumin increased slightly from the day of admission to discharge. Conclusions : Hyangsayukgunja-tang can be a choosable treatment option for a serious antibiotics-associated diarrhea.

In this paper, a new index(joint index) which shows the higher confidence than that of the existing technical indices and has simple logical structure and an index which is an applied form of the existing index(OBV-I index) are proposed. The index characteristics which have been known are verified by choosing the three most used technical indices(ADR index, investment psychological rate and VR index) as samples. And the index characteristics of the joint index are compared to those of the OBV-I index. The comparisons are executed not by comparing the investment earning rate of each index but by calculating the unnecessary number of trade days in the total number of trade days according to the index.

Since the forest succession is changing process in the structure and function of a forest for the long period of time, the objectivity of the process could be improved through the development of model or statistical methodology. This study was carried out to estimate succession index based on climax index and species composition parameters, thereupon to compare the succession index with life form and species diversity so as to grasp the information of quantitative successional process for the six community types in the natural deciduous forest of Mt. Jumbong area. The results indicated that Quercus mongolica-Tilia amurensis community had the greatest succession index of 67.5, followed by Abies holophylla-Fraxinus mandshurica community with 67.4. Juglans mandshurica-Cornus controversa community was recorded the smallest value of 60.5. The succession index of overstory tended to increase considerably at the stage of steady state for all community types except Quercus mongolica-Tilia amurensis community. However, The index of midstory hardly varied as the forest succession would progress for all community types. The succession index was negatively correlated to wind-water dispersion type of life form and positively to animal dispersion type at the 5% probability level. On the other hand, the index was not significantly correlated to the species richness and Shannon's species diversity index.

Marine algal flora and community structure were seasonally examined at three sites in the vicinity of the Wolseong nuclear power plant in Korea from February to November 2006. A total of 126 seaweeds including 25 green, 31 brown, 70 red algae, and 1 marine plant were identified. The greatest number of species occurred at Jeonchonri (101 species) followed by intake (88 species) and discharge (29 species) during the study period. Of 126 seaweeds, 76 annuals and 13 warm tolerance species were recorded. Dominant species based on important value (IV > 10) were Ulva pertusa and Enteromorpha linza at intake, U. pertusa and Padina arborescens at discharge, and Sargassum horneri and Corallina pilulifera at Jeonchonri shore. Annual average biomass exhibited a wide range of variations, from 40.67g m-2 in dry weight at discharge to 133.69g m-2 at Jeonchonri. Among six functional groups, dominant group was coarsely-branched form at intake and Jeonchonri, but it was different at discharge site as filamentous form. Seaweed community structures of discharge site were distinguishable in decreasing species richness, biomass, species diversity index (H’), richness index (R), and evenness index (J’). Also, the ratios of green algae, warm tolerance species, annual algae, filamentous form and dominance index (DI) remarkably increased. Such phenomenons of discharge site are usually found under environmentally stressful conditions such as high disturbance. Thus, I can conclude that the heated effluents of nuclear power plant act as environmental stress influencing seaweed community structures and it can be detected with various community indices.

The primary purpose of this study is to compare printed index and abstract user's behaviours with digital index and abstract user's behaviours, and to verify of structured characteristics of a printed index and abstract. The major findings are as follows: (1) When the research topic is not specified enough, users tend to rely on printed indexes and abstracts search, whereas they utilize digital form in order to do retrospective search in the stage of research when the topic is determined. (2) Printed index and abstract users are expecting small number of literatures in search, whereas digital index and abstract users are expecting large number of literatures to be found The former are more satisfied with the result of search than the latter. (3) Digital index and abstract users experience more search failure than printed Index and abstract users. When they fail to find wanted materials, both users turn to the other form of indexes and abstracts. (4) Printed index and abstract users shows significantly less knowledge on online searching than digital index and abstract users.

1. Objectives Theoretically Healthy Condition of four constitution is based on intact state of four fundamental factors - digestion, urination, perspiration, defecation. Each one of these four factors is specifically related to its respective constitution. We made SHI(Sasangin Health Index) 10 items from four factors, and examined clinical efficacy of the four factors as index of health status in four constitution. 2. Methods and Procedures We offered QSCCII, SHI and SF-36 questionnaires to adults who had a periodic medical examination. 233 adults were classified to one of four constitution. We compared means of 8 scale scores of SF-36, and computed the correlation coefficient between 8 scale scores of SF-36 and 10 item scores of SHI in four constitution. 3. Results In Soyangin, stool volume and frequency are weakly correlated with health status(P<0.05). In Soeumin, appetite is weakly correlated with health status(P<0.05). In Taeumin, there is no correlation between perspiration and health status. 4. Conclusions 2 factors - digestion, defecation - had clinical efficacy as index of health status.
