Recently, the range of using Internet in business is expanding rapidly. And through Internet, companies are strengthening both their internal efficiency and their external competitive advantage in the market. In recent years, building and managing companies' web sites are becoming unavoidable tasks in business. Such a trend is becoming more imperative in business over the world. There is a great deal of research in progress to study the cases of companies with increasing performance from the use of their Internet web sites. But it is considered that there has not been enough of study in the area of levels of Internet application in business especially in strategic areas and application levels among countries. This research is in the same line of the research that was carried out on such topics in 1999. study in 1999 showed that there are significant differences in the usage levels of Internet in business between countries with long history of using Internet and those who are not. The 1999 study also suggested the model on development stages of Internet usage in business. This study is the continuation of the 1999 research and used two years of data to compare and analyze the trend of the Internet development stages in leading corporations in Korea, U.S.A., and Japan. This study found that there have been significant developments in the ability to use Internet in business in three countries. The differences in Internet usage level in each stage among different countries are compared and analyzed in this study.

Thirty one cases, 18 females and 13 males, were operated on for patent ductus arteriosus. There were three adult cases. Patent ductus arteriosus alone was present in 27, while in 4 there were significant associated cardiovascular anomalies. No deaths occurred in 24 patients isolated patent ductus a' eriosus without and with mild to moderate pulmonary hypertension. Severe pulmonary hypertension was present in 4 patients with an isolated patent ductus. An operative death occurred in the 2 patients in this group. One of them died as result of the tearing of the ductus during surgery. The remaining case died 3 days postoperatively., Patent ductus arteriosus with congenital cardiovascular anomalies was present in 4 patients. Single operative death occurred 7 days postoperatively because of bronchopneumonia of right lung and atelectasis of the left lung. There was an increased mortality when patent ductus arteriosus was associated with severe pulmonary hypertension. All survival patients showed very satisfactory postoperative results.

해양 갈조류를 생물흡착제로 이용한 납흡착 특성 연구

서정호,감상규,오영희,이동환,이민규 동의대학교 기초과학연구소 1998 基礎科學硏究論文集 Vol.8 No.1

Lead sorption performances by biomass of nonliving, dried marine brown algae Undaria pinnatifida, Hizikia fusiformis, and Sargassum fulvellum used as biosorbent materials were investigated. As the amount of biosorbent materials added was increased, the lead removal by biosorbent materials increased but the lead biosorption capacities decreased. However, with increasing initial lead concentration the lead biosorption capacities by the biosorbent materials increased but lead removal efficiencies decreased. In the range of initial lead concentration(C_0) 10-500 mg/L the lead biosorption capacities and removal efficiencies by the biosorbent materials increased with increasing pH. Among the biosorbent materials used in this study, the lead biosorption capacities decreased in the following sequence: U. pinnatifida $gt; H. fusiformis $gt; S. fulvellum. The lead biosorption by biosorbent materials were expressed by the Langmuir isotherm better than the Freundlich isotherm. The biosorption rate could be expressed by the first order reaction rate equation for initial lead concentration like that r_ad = 0.288C_0 for U. pinnatifida, r_ad = 0.255C_0 for H. fusiformis, and r_ad = 0.161C_0 for S. fulvellum.

The problem is not to have local feature as tourist resort. 2. The present candition of tourist enterprise: The number of the tourist enterprise in Taegu district is 98, but the tourist industry is only 4.6percent of our country, therefore the speed of tourist development is reduced because of causing over competition by the over prejudiced tendency of the industry compared with other. district and some small industry. 1) The industry of tourist lodging: We have 14 tourist hotel and 944 rooms in Taege district, We are greatly underdeveloped in the scale and the content compared with the international standard. 2) Travel industry: Because of the revision of concerned law in 1987, 7. 1, the number of registered travel indnstry is 53, but the interaction of the travel industry is lacked, therefore the conflict between local travel industry is deepening. 3) Other tourist concerned industry: In hotel incidental, there are no casino, and a turkish bath, on account of the lack of selling tourist souvenir and tourist photo-shops. We cannot reflect the high consumption of the tourist. Ⅳ. Direction for the increase of attracting foreisn tourists. 1.

서환조,박명재,고경식,백영한,조유정,양현종,류경남,정형근,전정열 대한감염학회 1992 감염 Vol.24 No.1

Human sparganosois was reported more than 100 cases in Korean population. However no case reported yet in Korea as a patient was infected by sparganum from other geographical area, such as Thailand. The case we are reported here is a 38 year-old Korean male who had been suffered from mass being a small, round and soft consistance in upper portion of his right thigh. The patients stated that he had an opportunity to eat living snake in Bangkok, Thailand during trip. As therapy praziquantel (75㎎/㎏/day) was given p.o. for 14 days, but in vain to cure. Following medical treatment, surgical exicision was performed to remove a alive, soft, whitish-milky, mobile and elongated sparganum. Serlogical test by micro-ELISA for sparganum-specific antibody revealed a high serum antibody level of absorbance 0.67 (positive criterion: absorbance 0.22).

인공신경망 모델을 이용한 주식시장에서의 투자전략에 관한 연구

서영호,이정호 한국경영과학회 1998 한국경영과학회지 Vol.23 No.4

Since the late 1980s. an increasing number of neural network models have been studied in the areas of financial prediction and analysis. The purpose of this study is to investigate the possibility of building a neural network model that is able to construct a profitable trading strategy in the Korean Stock Market. This study classifies stocks into future market winners and losers from the publicly available accounting information and builds portfolios based on this information. the performances of the winner portfolios and the loser portfolios are compared with each other and against the market index. The empirical result of this research is consistent with the traditional fundamental analysis where it is claimed that the financial statements contain firm values that may not be fully reflected in stock prices without delay. Despite the supporting empirical evidence, it is somewhat inconclusive as to whether or not the abnormal return in excess of market return is the result of the extra knowledge obtained in the neural network models derived from the historical accounting data. This research attempts to open another avenue using neural network models for searching for evidence against market efficiency where statistics and intuition have played a major role.

Four cases of double superior vena cava were noted among 70 congenital cardiac malformation patients who were operated on in this departrment during the past five years. The first case was associated with ventricular septal defect, the second with tetralogy of Fallot, the third with Levocardia accompanied by complete transposition of the great vessels and pulmonary stenosis, and the last with patent ductus arteriosus. The persistence of the left superoir vena cava was confirmed by cardiac catheterization, vena-cavogram, and direct vision during operation. During this period 23 patent ductus arteriosus, 28 tetralogy of Fallot, and 5 cases of ventricular septal defect were operated on in the department. Each case had right sided superior vena cava in addition to the left one, i.e. double superior venae cavae.
