We intended to know whether all of the patients with asymptomatic microscopic hematuria should be urologically investigated routinely. We reviewed the medical records with asmptomatic microscopic hematuria from January 1995 to December 1997. Urological studies included intravenous urography or ultrasonography, urine cytology, cystoscopy and biopsy, urine AFB smear and culture and urine PCR for AFB. The age with patients ranged from 9 to 74 years(mean age: 39.7 years). Benign diseases were found in elderly patients and patients with high degree of hematuria, but there was no patients who had urological malignant disease. According to the results, we suggest that follow-up with urine cytology is sufficient to younger patients or low degree of hematuria with asymptomatic microscopic hematuria.

We intended to determine the usefulness of window operation for adult hydrocele repair. We reviewed medical records of 132 patients from January 1995 to June 1998 with primary hydrocele and evaluated complications and recurrence rates of eversion and/or excision, plication, and internal drainage technique. Recurrence rate was highest in internal drainage technique as 85.2%, and those of eversion and/or excision and plication technique were 1.3% and 4%, respectively. Complication rate was highest in eversion and/or excision technique, and lowest in internal drainage technique. Although complication rate was lowest in window operation, this operation could not be successful due to high recurrence, and we suggest that this operation should be abandoned for hydrocele repair.

Background and objectives: Many conditions are responsible for the pathophysiology and progressive mechanisms of congestive heart failure. More recently, it has also become evidence that another class of biologycally activated molecules generically reffered to as cytokine these are also over expressed in congestive heart failure. Therefore, the purpose of this study was to measure concentrations of tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) in mild to severe symptoms of heart failure and compare their values with those found in normal control and analysed correlation relationship between cytokine level, clinical findings and hemodynamic indicies. Subjects and Methodology: Levels of TNF-α and IL-6 were measured on pulmonary artery during cardiac catheterization in heart failure patients(n=32) and normal subjects(n=8) as well as physical examination and echocardiogram. Cytokines assay were performed on plasma using commercially available ELISA(Enazyme-Linked Immunosorbent Assay) kits. Results: Although the levels of TNF-α and IL-6 tend to increase in congestive heart failure group, the cytokines level was not made significantly statistical difference between congestive heart failure group and controls. When analyzing the correlation between the levels of PCWP(pulmonary capillary wedge pressure) and cytokines(TNF-α, IL-6), respectively, there were statistically significant correlation coefficient 0.32,(p<0.05), 0.39(p<0.01). The cytokine IL-6 and pressure of pulmonary artery were significant correlation.(correlation coefficient 0.36, p<0.02) More significantly, there was correlated with TNF-α and IL-6.(correlation coefficient 0.57, p<0.001) Conclusions: There was tended toward high concentration of TNF-α & IL-6 in congestive heart failure and significant difference for PCWP between TNF-α & IL-6, thus may be correlated with development and progression in congestive heart failure.

A feasibility study was performed to see the welding possibility of dissimilar thin-plat materials. These materials were welded for finding the optimum welding condition, and evaluating the soundness of welding zone. The welding was attempted under the condition of laser power 500~600W, pulse width 1.0~2.5ms and frequency 11~18Hz. In this study, the highest tensile-shear strength was observed at laser the low frequency. The suitable welding condition can be obtain at the large pulse width and the low frequency.

A synthesis of (Z, Z)-3, 13-octadecadien-1-yl acetate, one component of the sex pheromone of Synanthedon hector, Butler is described. Starting from 1,9-nonanediol, a sterocontrolled synthesis of (Z, Z)-3, 13-octadecadien-1-yl acetate with high sterochemical purity was achieved by the use of Wittig-olefination reaction and catalytic hydrogenation for the introduction of (Z)-double bond.

The building energy conservation possibility by introducing personal environment module(PEM)system was analyzed by DOE-2.1E building energy analysis program on the 6 stories office building. The results showed energy consumption of the building with PEM system could be increased more than the conventional VAV system when the occupant was not decreased. But the energy consumption rate in the building with PEM could be equal to VAV system when approximately 20% of the occupant is decreased. As a result, basically PEM system can consume more about 9.2%energy than the VAV system, but it can also have the possibility to save energy about 11.4% if it is operating with energy conservative way.

군매장의 효율적 POS시스템 운영방안에 관한 실증적 연구 : 공군과 해군의 매장관리 시스템을 중심으로

POS 시스템은 광범위한 적용대상을 가지고 있다. POS 시스템은 편의점이나 백화점과 같은 유통업체로부터 활용되기 시작하였으나 판매정보 이외에 기존 수집 자료를 기초로 상품정보와 재고관리, 수발주에 따른 물류관리, 고객관리, 인사관리에 이르기까지 종합적인 정보를 제공하는 시스템으로 발전되어 나감으로써 제조업체뿐만 아니라 공공기관에 까지 활용되고 있으며 기업의 통합적인 물류관리를 위하여 필수불가결한 시스템으로 자리잡고 있다. 본 연구는 군에서의 효율적인 POS 시스템의 운영방안을 살펴보려 한다. 영리기업이 POS 시스템을 활용하여 정보를 신속, 정확하게 처리함으로써 고객 만족 또는 이윤추구목적은 달성할 수 있었다면 군도 특정영역에서 조직 목표를 달성하는데 POS 시스템을 유용하게 유효한 성과를 거둘 수 있을 것으로 기대된다. POS system was initially introduced to some leading circulation businesses such as CVS or department stores. Since then POS system has been developing into an integral information system, enlarging its range of application - from basic data collection to product information; inventory management; customer service; and personnel management. As circulation companies struggle to get more competitive edge, the number of companies that make strategic use of the secured information is soaring. In pace with the era of information revolution, military organizations have introduced POS system to some daily sales process at BX shops. Since the POS system will surely increase work efficiency, my suggestion, based on the survey, is that the navy should adopt POS system in its BX management. For better results to its full potential, POS system should be designed and implemented in consideration of various demands from relevant departments. Lastly, some measures should be arranged in order to maximize its benefits.
