According to developing digital media, the delivery and the collection of information are changing with a variety of ways. Especially, digital, as it is, is easy for its sound, video and letter to be mixed. Therefore, media character, Audio-Visual will appear in total. Hypertext must be a basic form in the traveling way of media information which includes such digital Quality in originality. Taking advantage of digital media trait of hypertext , most users can make a research on a variety of studying method. On this thesis, a style of made-up hypertext is taking a part of recent digital culture, and I want to present a different method in research, using two hypertext skills, adventurous choice and joint origination

The objective of this study is to develop an optimal joint cost from the perspectives of both the manufacturer and the retailer. The integrated production-inventory model with Weibull distribution deteriorating items is assumed to have a constant demand rate. A limited retailer storage space and multiple delivery per order are considered in this model. A numerical example including the sensitivity analysis is given to validate the results of the production-inventory model.

In this paper we propose an effective genetic algorithm for solving the integrated inventory and routing problem of supply chain composed of multi-warehouses and multi-retailers. Unlike extant studies dealing with integrated inventory and routing problem of supply chain, our model incorporates more realistic aspect such as positive inventory at the multi-warehouses under the assumption of inventory policy of power of two-replenishment-cycle. The objective is to determine replenishment intervals for the retailers and warehouses as well as the vehicles routes so that the total cost of delivery and inventory cost is minimized. A notable feature of our algorithm is that the procedure for evaluating the fitness of objective function has the computational complexity closing to linear function. Computational results show effectiveness of our algorithm.

The subway concrete box structure can`t establish expansion joint because of animal power delivery of the subway rail. In this case, As increase of structure volume, it is subjected to cause temperature crack. The temperature crack due to the heat of hydration classified a nonstructural crack. but it has a bad effect on durability of concrete structures. especially, in case of a subway concrete box structure, when a water-proof facilities is beaked on an outer-wall, the water leakage occurs through a penetration crack generated from a wall of the concrete structure too. This paper, for the subway concrete box structure, examined a condition of temperature crack occurrence by a heat of hydration concerned external temperature from analysing by a three dimensional finite element method.

The purpose of this paper was to propose the efficient strategies of internet fashion shopping malls to success in the internet shopping mall market growing rapidly. Representative 5 internet fashion shopping malls - Halfclub, Fashionplus, e-Hyundai, Hansol CSClub and LGeShop - were selected and in-depth interviews were performed to analyze their marketing 4P's strategies. The results of this study are as fellows. Five shopping malls'main targets are women in twenties and early thirties. The price strategies are various according to shopping malls'character. In general, there are small amounts of discounts on new products(about 5%) which are sold by department stores. Shopping malls executed delivery of goods by cooperation with distribution companies and direct distribution of subcontract companies. Shopping malls are sending e-mails to the members as a promotion strategy. CRM(Customer Related Management) is partially implemented. Joint purchase and various events are conducted frequently. Shopping malls guarantee exchange and refund services.

사회적경제조직은 그동안 다양한 유형과 분야에서 양적인 성장을 가져왔으나 주로 정부가 주도하는 형태로 추진되어왔고 아직 선진국과 비교해 볼 때 제도적 정비나 지원체계 및 지원방식 등 질적으로 개선해야 할 여지가 많다. 본 연구에서는 선행연구를 통해 나타난 사회적경제조직의 문제점, 사회적경제조직의 현황과 실태분석, 정책전달 체계, 사회적경제조직 발전의 장애요인, 활성화의 문제점 등을 검토하였다. 이를 통해 미래 사회적경제조직의 활성화를 위한 정책 방향과 추진과제를 제시하여 보았다. 그 결과 사회적경제조직의 활성화를 위한 정책방향은 민간·지자체 주도, 진출분야의 확대, 성장생태계 조성을 위한 맞춤형 지원, 다양한 연계협력이 필요하고 추진 과제로는 제도개선을 위한 법령제정 및 개정, 사회적경제조직의 역량개발과 교육, 다양한 연계협력체제 강화, 투자생태계 조성, 공동판로개척 등이 필요하다.

VRE 감염증은 항균제의 과다한 사용 후 출현하는 새로운 형태의 감염성 질환으로, 현재 심각한 임상 문제로 대두되고 있다. 최근 국내에서도 신경학적 장에나 당뇨병, 종양 등의 기저질환을 가진 성인 환자들에서 소수의 감염 예가 보고되고 있으나 소아기, 특히 신생아에서의 감염증은 잘 알려지지 않았다. 저자들은 생후 4일된 신생아에서 발생한 vancomycin 내성 E. faecalis 패혈증 l례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

The purpose of this study was to identify the risk factors of osteoporosis. The data were collected from women who visited Physical Examination Center of a university hospital located in Taejon during the period of September 1997-August 1998. The sample was divided into two groups(the osteoporosis group of 44 cases and the control group of 66 cases). The results were summarized as follows ; 1. Sociodemographic characteristics(education and family income) and BMI showed no significant difference between the osteoporosis group and the control group. 2. There was no significant difference in coffee, unbalanced diet, diet method and meal habit between the osteoporosis group and the control group. 3. The osteoporosis group reported more incidence of operative menopause due to hysterectomy and oophorectomy, but this was not statistically significant. There was no significant difference in use of oral pill use, past disease and family history of fracture between the osteoporosis group and the control group, but the odds ratio(OR 3.11, 95% CI : 1.30-7.41) of present illness was statistically significant in the osteoporosis group. 4. There was no significant difference in the reproductive history including number of delivery and abortion and feeding method between the osteoporosis group and the control group. 5. The osteoporosis group showed significant results of lower menopausal age, shorter duration of menstruation and longer duration after menopause compared to the control group. 6. The osteoporosis group reported significantly lower level of physical activity in such variables as work activity and walking time. 7. A logistic analysis showed that shorter period of menstruation, lower level of physical activity, non-alcohol drinking group, and presence of disease were related to the possibility of occurring of osteoporosis.

Purpose: To identify Osteoporosis and the related risk factors in middle-aged women, the descriptive survey was done. Method: The subjects were measured in 465 residents who were 40-60 aged healthy women. They underwent ultrasound measurement and health examination in G city's Health Center in Gyeonggi-do, Korea from July 2000 to March 2001. The self-reported questionnaire consisted of total 17 items about risk factors related to osteoporosis. The evaluation of bone density was based on ultrasound measurements of right heel. All data were analyzed by SAS-PC Program. Result: Mean age of the subjects was 46.7. Mean T score related to bone density was -1.30, ranged from -3.52 to 3.06. In diagnosis classification according to T score, 74.8% of subjects was normal, 12.9% was osteopenia, 12.3% was osteoporosis. Among risk factors, there were significant differences by age (t=15.35. p=0.000), parity (F=12.81, p=0.000), menopause status (t=22.05, p=0.000), period after menopause (F=5.20, p=0.006). The higher frequency of delivery, postmenopausal and longer period after postmenopause of subjects had the lower the bone density. Conclusion: It would be necessary to develop and apply the community-based health promotion program for middle-aged women to prevent osteoporosis.
