Importance of productivity improvement has been recognized in Korea manufacturing in recent years as a means of international competitiveness enhancement. Well-established productivity management is what is needed in manufacturing in order to improve productivity. Thus far, Korea manufacturing's emphasis for productivity management has been focused mainly on the measurement of labor productivity. Effective productivity management, however generally requires the following stages : establishment of productivity strategies, productivity measurement, productivity evaluation, productivity planning, and implementation of productivity improvement programs. In this study, company-based and plant-based "productivity management index systems(PIMS)"are developed for application to measurement and evaluation stages of Korea manufacturing's productivity management.

One aims to find out how the operation condition of secondary inlet angle effects the temperature distribution inside a small incinerator. A finite volume commercial code, PHONICS, is used to simulate the temperature field in an incinerator. The computational grid system is constructed by Multi-Block technique. The governing equations based on the curvilinear coordinates are used. Numerical experiments are done with the five variations of secondary air inlet. The temperature distribution is quantified by the statistical deviation of temperature in an incinerator. The computational analysis says that the certain angle of secondary air inlet could improve the uniformity of temperature distribution in an incinerator.

Low alloy steels for nuclear reactor are degraded progressively through microstructural changes due to high operation temperature and irradiation. Strength properties are the most important factors for the selection of materials and the determination of degradation degree. Interfacial properties affected by strengthening particles with the range of nm size and strength distribution in microstructures could not be tested by the conventional mechanical testing methods. Microindentation and nanoindentation technique have been studied as a alternative of conventional methods. Specially, nanoindentation technique with a μN load range and a nm residual indent size range has been highlightened as a tool which is very useful to determine those properties. Since each phase composing microstructure of steels has a characteristic hardness value, it is possible to characterize phase on the basis of that character. In this study, by using of microindentation and nanoindentation technique can be evaluated microstructural mechanical properties of low alloy steels manufactured under 7 different kinds of processes. Through the study, we verified potentialities whether or not indentation technique can be used as a method to determine degree of degradation.

Objectives : This study was conducted to estimate the incidence rate, and to identify the risk factors for the occupational low back pain among shipyard workers. Methods : The study subjects consisted of 9,784 workers who were employed in a ship-building industry (excluded workers who had a history of low pack pain before 1995 or did not take periodic health examination in 1995) . The cases were 220 people who experienced back pain from January 1, 1996 to December 31, 1998. To assess risk factors for occupational low back pain, Cox propotional hazard model was used. Results : During the recent three years from 1996 to 1998, the incidence rate per 1,000 persons was 7.8 in 1996, 8.8 in 1997, and 3.1 in 1998. The main causes of work-related low back pawn were sprain, strain and disc herniation. Lifting was the most common cause of back pain (35.3%) , and carrying (10.2%) and pulling (8.0%) were followed. In Cox proportional harzard model, independent risk factors for back pain were body mass index(R.R. ; 1.54, 95% C.1. : 1.06-2.25), shift work(R.R. ; 1.65, 95% C.1. : 1.19-2.28), and lifting heavy material(R. R., 3.95, 95% C.1. : 2.29-6.82). Conclusions . This study suggests that the risk factors of back pawn In shipyard work-ers were body mass index, shift work and lifting.

국균은 호흡기를 통해 유입되며 심한 면역기능저하 환자에서 기회감염을 일으키는 진균이며 주로 혈관을 따라 폐를 침범하고 심장과 골침범은 매우 드문 것으로 알려져 있다. 저자들은 급성 림프구성 백혈병 환자에서 발생한 침습성 국균 심내막염을 2예을 경험하였다. 19세 남자환자로 동종 조혈모세포이식 후 발생한 고열과 요통의 원인으로 감염성 심내막염 진단하에 수술결과 국균에 의한 감염으로 확증되어 수술적 절제술과 liposomal amphotericin B로 치료하였으나 국균 심내막염의 재발과 국균 척추염의 악화, 뇌 출혈로 사망하였다. 23세 남자환자로 관해요법 후 발생한 고열과 요통의 원인으로 국균 심내막염과 국균 척추염 진단하에 수술적 절제술과 amphotericin B로 치료하여 1년 2개월 동안 국균 심내막염의 재발은 없었으나 지속적인 백혈병의 재발과 국균 척추염의 악화, 침습성 폐 국균증으로 사망하였다. Although Aspergillus endocarditis has rarely been reported, it can cause fatal complications in hematologic malignancy patients and allogeneic stem cell transplant recipients. We experienced two cases of aspergillus endocarditis developed in acute lymphoblastic leukemia patients. Case; A 19-year-old patient developed Aspergillus endocarditis after allogenic hemopoietic stem cell transplantation. He was treated with surgical intervention and liposomal amphotericin B. He died of recurred Aspergillus endocarditis and cerebral hemorrhage probably related with aspergillosis of central nervous system. Case 2; A 23-year-old patient developed invasive Aspergillus endocarditis after induction chemotherapy. Aspergillus endocarditis was successfully treated by surgical intervention and amphotericin B. He died of refractory neutropenic fever and sepsis after the third relapse of leukemia and repetitive chemotherapy. He probably had invasive pulmonary aspergillosis without evidence of endocarditis recurrence. Because the mortality of Aspergillus endocarditis is very high, early diagnosis and surgical intervention are very important for better outcome.
