인터넷 취업알선은 디지털시대로의 변화에 따라 취업의 새로운 패러다임으로 대두되고 있다. 인터넷 취업알선의 대두를 거래비용이론의 접근에 따르면 탐색비용을 비롯한 거래비용은 줄어드는 대산 도덕적 해이와 역선택 비용은 증가하는 것으로 분석된다. 따라서 인터넷 취업알선이 확산되기 위해서는 두가지 방안이 제시될 수 있다. 단기적으로는 도덕적 해이와 역선택을 축소하기 위하여 개인정보 보호 및 보안 등을 비롯한 시장질서를 정립하는 것이며, 장기적으로는 새로운 비용의 증가분을 담보하는 신뢰의 구축을 위하여 채용부터 인사노무관리 및 해고에 이르기까지 전과정을 수행할 수 있는 인적자원 종합 기업을 육성하고 양성하는 것이다. The internet employment service becomes new paradigm of recruiting in the digital ages. Transaction cost approach explains that emergence of internet employment service results from the reduction of selection and recruiting cost. Because transaction cost is reduced utilizing internet tool, internet employment service becomes very popular. But that service increase the cost of moral hazard and adverse selection. The effective strategy of internet employment service enlargement make, shortly, a rule of internet employment market including solving the security and safety problems. The long term strategy i s developing the human resource firms with the integrated HRM functions in order to basically solve the moral hazard and adverse selection problem by the formation of trust.

Both genetic and environmental factors play important roles in the pathogenesis of Parkinson Disease (PD). The contribution of many environmental factors including dietary factor remains unproven. The purpose the study was to investigate the dietary habits, nutrient intake and dietary quality of Korean PD patients according to the duration of disease. PD patients were recruited from K and S university hospitals from May 2005 to January 2006. This study was carried out after approval by the Institute Review Board (IRB). British Brain Bank criteria was used to diagnose PD. The subjects were classified into 2 groups based on the duration of PD: < 25 months and ≥ 25 months groups. General characteristics, anthropometric measurements, food habits and dietary intakes were investigated. The results of this study were as follows: 1) The mean age of < 25 months group (66.9 ± 8.0 yr) was significantly higher than that of ≥ 25 months group (62.2 ± 8.8 yr) (p < 0.05). No significant differences were found for academic background, occupation, living status and social activity, however, numbers of diseases, exercise and family history of PD were significantly different. 2) Anthropometric measurements were not different between the two groups. 3) The frequency of taking snacks was significantly higher in < 25 months group and the amounts of alcohol consumption were significantly higher in ≥ 25 months group. 4) Daily intakes of most nutrients were very low compared with DRI. 5) The MAR score was significantly lower in < 25 months group (p < 0.05;) however, the scores of DVS, DDS and DQI were not significantly different. As a conclusion an overall nutrient intake and dietary quality of the Parkinson's Disease patients need to be improved regardless of duration of the disease and a well-balanced diet should be emphasized.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

The color intersities of melanoidins and the contents of HMF in skim milk by heat treatment. The contents of HMF in skim milk were detected in all heat-treated skim milk by colormetrical method and HPLC method. The color intensities of melanoidins showed significant dependence on reaction temperature and time. The contents of HMF in skim milk were detected in all heat treated skim milk by colormetrical method. While they were not detected by HPLC method when skim milk was heated at the temperature 70℃ for 30, 50 and 70 minutes. It showed significant dependence of reaction temperature and time.

이주열,이윤석 대한보건협회 2002 대한보건연구 Vol.28 No.4

The purpose of this study is to investigate the effects of smoking school cessation program in the adolescent smokers. In this study, the anti-smoking class and the follow-up support program developed an effective method to help teenagers from stopping smoking. The results of this effort has been analyzed in this paper. At first, the quantity of cigarettes smoked between groups made no difference, but there was an obvious difference in the rate of people who stopped smoking and in the quantity of cigarettes smoked. According to the results of the study, we can conclude that the anti-smoking class is an important method in strengthening ones will to quit smoking, but it has a minimal effect in prolonging the positive effects for the long term. To keep the program attendees smoke-free, continuous moral support is needed; here the follow-up support plays a big role not only in raising the rate of success in the level of reformed smokers, but also in lowing the quantity of cigarettes smoked.
