조종래,엄태현 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.3
Objective : It would be frequent that routine tests in clinical microbiology laboratory are interrupted more than 2 days because of the five-day workweek legislation, which is thought to be launched near future in Korea. We investigated the impacts of the extended storage of bacterial colonies in secondary culture media on the bacterial identification and antibiotic susceptibility tests. Methods and Materials : Five strains of Staphylococcus aureus, 4 coagulase negative staohylococcus(CNS), 3 Escherichia coli. 4 Pseudomonas aeruginosa, and 4 Acineto-bacter baumannii, which are frequently isolated from clinical samples in Ilsan Paik Hospital were used for this study. We did the identification and antibiotic susceptibility tests by VITEK 2 system, using colonies stored for 2 days, 4 days, and 6 days in room temperature. Fesults : There were no changes in identification until 6 day storage. The percentages of the organism-antibiotic combinations in which minimum inhibitory concentration(MIC) changed more than 1 dilution were as follows; S. aureus 9.0%, CNS 17.5%, E. coli 10.0%, P. aeruginosa 23.7%, and A. baumannii 22.4%. The percentages with more than 2 dilution changes, which are considered to be significant, were as follows: S. aureus 0%, CNS 3.8%, 2. coli 1.7%. P. aeruginosa 5.3%, and A. baumannii 6.6%. The very major errors observed in S. aureus, CNS, E. coli. P. aeruginosa and A. baumannnii were 0%, 1.3%, 1.7%, 0% and 2.6%, respectively; for minor errors, 1.0%, 0%, 1.7%, 6.6% and 6.6%, respectively. Major errors were not observed in any of the organism-antibiotic combinations studied. Conclusion : We thought that it would be acceptable for clinical microbiology laboratory to delay the antibiotic susceptibility tests during holidays.

Since SME (Small and Medium Enterprise) sector accounts for about 85% of Korean employment, creating jobs through SMEs is an important task. The growth of SMEs leads to the revitalization of the national economy by creating jobs and income in the local area. Therefore, it is important for government and related public institutions to support SMEs, which play an important role in the national economy, to build a competitive economy. The purpose of this study is to evaluate the effectiveness of the support program for the SMEs in the local area, especially in Busan. Therefore, we analyze the performance of companies and compared effectiveness between the b beficiaries in MOTIE (Ministry of trade,industry and energy) (Group A), TechnoPark (Group B) and other regional public institutions (Group C) and non-beneficiaries(comparison group, Group D). The results were represented by the average rate of sales growth rate and the average rate of employment growth according to the company size, the establishment of company research institutes, the average number of patents, the designation of venture company, the presence of Innobiz (Innovation Business) certification, and the number of R &D employee. The average sales growth rate and the average employment growth rate, which are the main indicators of the results of the validity analysis, as follows. As a result, the average sales growth rate of beneficiaries is 80.04%, which is higher than the average of non- beneficiaries - 26.2%. And the support effect of TechnoPark (Group B) is the highest, and the support effect of other regional public institutions is next. On the other hand, it is shown that dependency of the average employment growth rate on the company size is significant, and that the average employment number of both beneficiaries and non-beneficiaries increases, but the significance level is not significantly different at the 5%. Therefore, it is shown that the relationship of key indicators that improve the efficiency in the beneficiaries by the government support lead directly to the improvement of the performance of sales and employment.

저자들은 원내감염의 주 원인균 중의 하나인 Methicillin 내성 Staphylococcus aureus(MRSA)를 기준으로 하여, 인제대학교 부속 상계백병원의 원내 감염율을 진단하였고, 의료인군의 비강과 손에서 MRSA의 검출율을 조사하여 보균자를 파악하고 또 원내감염의 전파경로를 추정하여 병원내 감염의 기회를 줄이고자 본 연구를 시행하였다. Methicillin resistent S. aureus(MRSA) is one of main causative bacterias of nosocomial infection. Recently their prevalent rate has continuously increased in Korea, so we have studied the incidence rate of MRSA strains which was isolated from microbiology laboratory in Sanggye Paik hospital between September 1st, 1993 and february 28th, 1994. And we compared the incidence rate of MRSA among various groups ; physicians, nurses, aiders, and medical laboratory technicians. The incidence rate of MRSA among S. aureus was 57% (N=227). Among 87 hospital personnels screened, the nasal cavity and hand carrier rates of MRSA in hospital personnel groups which have had direct contact to patients were 78.6% and 50%, respectively, but the one of MRSA in medical laboratory technician group which has not had direct contact to patients were 0% and 0%, respectively, of all isolated S. aureus. We concluded that hospital personnels were primarily infected by MRSA from patients and spread of MRSA from patients to patients in hospital appeared to have occurred secondarily by direct contact from hospital personnels who were nasal cavity or hand carrier of MRSA.

본 논문은 연속주조에 있어서 내부결함의 주원인 벌징현상을 탄소성과 크리프를 동시에 고려한 3차원모델을 이용하여 2차원모델을 이용한 해석에서 알 수가 없는 측면의 영향을 평가하는데 목적이 있다. 각 부분의 빠른 해석결과를 알 수 있도록 응고해석과 벌징해석을 잇는 전산프로그램을 개발하였다. 2차원 비정상상태에 열전달방정식을 유한차분법을 이용하여 응고해석을 실시하여 주조속도와 슬래브폭에 따른 응고현상을 확인하였다. 벌정해석에 있어 크리프변형의 영향을 분석하였으며, 특히 주조방향의 변형률에 큰 영향을 미치는 것을 확인하였다. 슬래브폭 변화의 영향을 확인하기 위해 2차원해석과 3차원해석의 벌징량과 변형률의 차이를 비교한 결과, 슬래브 폭이 두께의 3배보다 작을 때에는 반드시 3차원 해석이 필요하다는 것을 확인하였다. In this paper, the bulging behavior of the solidified shell in continuously cast slabs has been numerically analyzed using three-dimensional elasto-plastic and creep finite element method. Three-dimensional model has been applied. in order to investigate the effect of the narrow face shell on restraining the bulging deflection. Solidification analysis has been carried out by two-dimensional finite difference method. In this way. strains occurring at the solidification front near the narrow face of the slab. as well as those occurring in the board face have been computed. The accuracy of the model has been verified by comparing the results of analysis with those of experiment. In addition. the effect of the slab width and casting speed on the bulging has been discussed.
Hydroxychloroquine 치료 후 38일과 40일에 재발한 삼일열 말라리아 2예
조종래,엄태현,정재원 대한임상미생물학회 2005 Annals of clinical microbiology Vol.8 No.2
There are two stages in the life circle of Plasmodiumspp in humans: exoerythrocytic and erythrocytic stages. Hydroxychloroquine is the major chemotherapeutic agent against malarial parasites in their erythrocytic stage. The recurrence of Plasmodium vivax malaria, which is usually caused by an inadequate treatment or the presence of drug resistant parasites, has been reported frequently in the world, but rarely in Korea. We experienced two patients who recurred with P. vivaxmalaria after hydroxychloroquine therapy, and treating with insufficient doses of the drug was suspected as the cause of the recurrence.

Backgroud: The concentration of Protein Induced by Vitamin K absence or antagonist-II (PIVKA-II) has been described to be increased in patients with hepatocellular carcinoma(HCC), along with its elevation in vitamin K deficient states by warfarin or discoumarol treatment. The aim of the study was to investigate its clinical value in diagnosing hepatocellular carcinoma(HCC) in comparison with α-fetoprotein(AFP). Patients and Methods: Measurements were performed in sera of 47 patients with control group (acute and chronic hepatitis, liver cirrhosis, alcoholic hepatitis and gastrointestinal malignancies) and 29 patients with histologically proven HCC. Commercial research ELISA test (PIVKA-II test, SCL, Japan) using murine monoclonal anti-PIVKA-II antibodies were used and compared with a commercial AFP-EIA(Abbott, USA) Results: The sensitivity rates for PIVKA-II and AFP were 90% and 69%, respectively, the rate was 97% when PIVKA-II was used in combination with AFP (PIV KA-II+AFP). A significant correlation was seen between PIVKA-II values and AFP values(r=0.57, p〈 0.01), and between tumor size and PIVKA-II values(r=0.672, p〈 0.01). Conclusion: PIVKA-II has a stronger correlation with size of HCC than AFP. PIVKA-II is a useful marker for HCC and could be used in combination with AFP.

Japanese government enacted a Manpower Supporting Act for the SMBs in order to address the problems of the SMB workforce in 1991. The ministry of labor and ministry of commerce jointly proposed the act to handle out not only the workforce scarcity but also youth unemployment. The act was heartily discussed and accepted by both Japanese Houses. The government and the assembly thought workforce scarcity mainly stem from the poor work conditions of SMBs. So, the core part of the enactment of Manpower Supporting Act for the SMBs was to improve the working conditions of SMBs. The act makes the government to set up national plans to improve the condition of getting personnel. The government accredits the businesses that have proper plans to improve personnel management conditions. The accredited businesses hold the rights to get government subsidies and the obligations to report the process of employment improvement. The act has been revised 24 times since it had been enacted. In 1995, the act enlarge the scope of accredited businesses to each business from organizations. Lots of exceptional favors are included in 1995 revision. In 1998, the government heads the main purpose of the law from employment improvement to the creation of decent job opportunity. The government also included the newly start-up businesses to support list. Other revisons are mainly subjected to revisions of other domestic laws. The backgrounds of enacting Manpower Supporting Act for the SMBs in Japan are similar with those of Korean Manpower Supporting Act for the SMBs.
