This study focuses on investigating and analyzing overall information use behavior of the health fields researchers. Questionaries were 116 researchers in there nursing university or college and EMT college. Four areas were tested on the basis of the purpose that there would exist unique characteristics in the information seeking behavior of health fields researchers. The findings of the study shows that health fields researchers prefer monographs and journals; they tend to use current materials; the first information source for their research activities is the cited references in the book or journal article; they are likely to delegate literature searching to the librarian, but they tend to conduct direct searching in online setting; in general, they react positively for the rapid change in information environment caused by recent development of information technology. It is emphasized that to design an efficient information system and provide an effective information service in the health science related library or information center, it is essential to consider the major characteristics and attributes of health fields researchers in terms of their information use behavior.

Cyanobacteria are the dominant phototrophic bacteria in water environments. Here, the diversity of cyanobacteria in seven Korean reservoir waters where different levels of algal blooms were observed during the summer of 2002, was examined by T-RFLP analysis. The number of T-RF bands in the HaIII T-RFLP profiles analyzed from those water samples ranged from 20 to 44. Of these, cyanobacteria accounted for 6.1 to 27.2％ of the total bacteria. The water samples could be clustered into 2 groups according to the Dice coefficient of the T -RF profiles. The eutrophic Dunpo and oligotrophic Chungju reservoirs were selected, and several representative clones from both reservoir waters analyzed for the nucleotide sequences of their 16S rDNA. The major clones were found to belong to the Microcystis and Anabaena species in the waters from the Dunpo and Chungju reservoirs, respectively, which was in agreement with the T-RFLP result. That is, the Microcystis and Anabaena species were dominant in the eutrophic and polluted Dunpo and oligotrophic Chungju reservoir waters, respectively. These results indicated that there is a correlation between prevalence of cyanobacterial species and levels of pollution in reservoir waters.

Due to the potential growing capability that reflects future value, the market value of internet business companies (IB) are still evaluated high although major players like Amazon continuously suffer losses. Then, how do investors valuate the potential growing capabilities given that traditional financial/accounting based valuation approaches seem to be inappropriate for IB. This study attempts to provide an answer to this issue. We, therefore, analyzed the predictability of various accounting and non-accounting variables for IB value. These include book value, net income, unique visitors, page view, reach rate, public float and institutional holdings. Because of being in infant stage and difficulties in obtaining necessary web traffic data, sample of 20 pure IB were selected from Korea Stock Exchange Market, KOSDAQ, and informal market. The results of this study showed that web traffic date had the strongest relationship with IB value. In particular, unique visitors and reach rate were found to be best predictors for IB value while page view was reasonable indicator. Interestingly, net income was not found to related to IB value. This calls for an attention to the typical characteristics of IB that my hinder the usage of traditional valuation approaches for IB. Another results revealed that none of both public float and institutional holdings was significantly associated with IB value, indicating market’s supply-demand factors were less important than traffic information.

The purpose of this study is to make a Web Color Data Base for practical design system for domestic fashion industry. The market segmentation was based on the results of the previous studies and the characteristics of fashion consumers. Finally, the 14,121 color samples are collected from the survey of 55 manufacturers of domestic fashion industry and 116 fashion brands of major department stores. These color samples are analyzed by the Munsell's H V/C and CIE L*a*b* value. The representative colors are selected concerning the density in CIE L*a*b* color space and the distance between the color samples. As a result, We suggested 2213 representative colors. Also, this color data was constructed on Web site. The data were sorted by the market, season and color code. In addition, the representative color sample book was made for the prototype of .

이 논문에서는 1876년에서 1910년에 이르는 개화기에 국가적 차원에서 일어난 초등수학교육의 변화를 정리하였다. 이를 위해 개화기를 갑오개혁이전, 갑오개혁, 통감부시기로 구분하고 각 시기별로 초등수학교육의 주요 변화를 살펴보았다. 갑오개혁이전시기부터 산술교육의 필요성이 인식되었으며, 갑오개혁시기에 산술교육은 본격적으로 국가교육과정이 되었다. 특히 갑오개혁시기에는 국한문혼용의 초등수학교과서가 발간되었다. 일제의 간섭이 본격화된 통감부 시기에는 '간이'와 '이용'의 교육정책에 따라 산술교육도 축소 또는 약화되었다. 이 시기에 발간된 초등교원용 산술서는 특기할 만하다.

The main objective of this research is to investigate whether the RFM (recency-frequency-monetary value) information of a customer's redemption behavior of loyalty points can improve the prediction of future value of the customer. The conventional measurement of customer value has been primarily based on purchase transactions behavior although a customer's future behavior can be also influenced by other interactions between the customer and the firm such as redemption of rewards in a loyalty program. We theorize why a customer's redemption behavior can influence her future purchases and thereby the customer's total value based on operant learning theory, goal gradient hypothesis, and lock-in effect. Using a dataset from a major book store in Korea spanning three years between 2008 and 2010, we analyze both purchase transactions and redemption records of over 10,000 customers. The results show that the redemption-based RFM information does improve the prediction accuracy of the customer's future purchases. Based on this result, we also propose an improved estimate of customer lifetime value (CLV) by combining purchase transactions and loyalty points redemption data. Managerial implications will be also discussed for firms managing loyalty programs to maximize the total value customers.

Stock price multiple is one of the most well-known equity valuation technique used to forecast equity price. It measures by multiplying "the ratio of stock price to a value driver" by a value driver. The value driver can be earning per share (EPS), sales or other financial measurements. The objective of price multiple technique is to evaluate the value of assets and compare how similar assets are priced in the market. Although stock price multiple technique is common in financial filed, studies on the application of the technique in Thailand is still limited. The present study is conducted to serve three major objectives. The first objective is to apply the technique to measure value of firms in banking sector in the Stock Exchange of Thailand. The second objective is to develop composite price multiple index to forecast equity prices. The third objective is to compare valuation accuracy of different value drivers of price multiple (i.e. EPS, Earnings Growth, Earnings Before Interest Taxes Depreciation and Amortization, Sales, Book Value and Composite Index) in forecasting equity prices. Results indicated that EPS is the most accurate value drivers of price multiple used to forecast equity price of firms in baking sector.

The "Ojangyukbudo五臟六腑圖", cited in "Ojangmun五藏門" of "Euibangyuchwi醫方類聚", was written by Ho Eum, a woman Taoist master who lived in Dang Dynasty. She put stress on the medical theory of the five viscera and the six entrails to overcome the side effects of Oedansul[alchemy for immortality] which prevailed during the period of Dang, and established a medical system which was based on six viscera and entrails and combined with Taoist theories. The major features of "Ojangyukbudo五臟六腑圖" can be summarized in the six-part medical system, the diagrams which describe the principles of viscera and entrails in detail, and the methods of Suyang[修養法:mental training], Tonap[吐納 法:respiration] and Doin[導引法:physical training] for regulating the functions of viscera and entrails and curing diseases. The "Dongeuibogam東醫寶鑑", a medical book from Joseon Dynasty, accepted the methods of Suyang and Doin, and the "Yorayak要略", a transcript from Joseon's later period, accepted the Taoist medicine based on six viscera and entrails, combined it with the contents of "Dongeuibogam東醫寶鑑", thus composing a unique medical system. Especially, the "Yorayak要略" is a literature important for the study of Joseon's Taoist medicine.
