Aim: The aim of the present study was to evaluate retrospectively histopathologically-diagnosed lesions that were detected in the kidney after radical nephrectomy for a preoperative diagnosis of kidney cancer. Methods: The medical records of 83 patients (51 male, 32 female) were included. Preoperative staging was accomplished by various methods including physical examination, blood hemography and biochemistry, abdominal ultrasonography (US), chest x-ray, abdominal computed tomography (CT) and abdominal magnetic resonance imaging (MRI). Results: Totals of 70 patients underwent radical nephrectomy and 13 nephron sparing surgery. Of the 83 patients, 70 had malignant lesions (renal cell carcinoma, squamous cell carcinoma or other malignancies) 13 had a variety of benign lesions, the most frequently detected being oncoytoma (6), angiomyolipoma (3), xanthogranulamatous pyelonephritis (2), cortical cyst (1) and chronic pyelonephritic change (1). Conclusion: It was concluded that in spite of great technological developments regarding radiological imaging modalities such as US, CT and MRI, benign lesions might still be detected pathologically in patients who undergo radical nephrectomy with the preoperative diagnosis of renal cancer. But, all renal masses should be regarded as malignant and should be managed surgically otherwise proven benign.

Our aim was to test the hypothesis that preoperative serum levels of matrix metalloproteinase-7 (MMP-7) and -9 (MMP-9) and tissue inhibitor of matrix metalloproteinase (TIMP-1) levels correlate with pathological features. Serum levels of MMP-7, and MMP-9 and TIMP-1 were determined in 90 bladder cancer patients and 40 healthy controls using an enzyme linked immunosorbent assay. Preoperative serum MMP-7 and MMP-9 levels were significantly higher in cancer patients than control groups (p<0.001). In contast, serum TIMP-1 levels were lower (p<0.001). Alteration in MMP-7, and MMP-9, and TIMP-1 production may contribute to tumor angiogenesis and be associated with clinic-pathological features.

This paper is aimed to investigate fundamental phenomenon by aerobic digestion process in night-soil treatment experimentally. First of all, digestion time is divided into 5, 10, 15, 20 and 25days and return sludge rate is also divided into 15, 30, 45 and 60% in order to investigate optimum digestion time and return sludge rate. In the following, according to the determined digestion time and return sludge rate, observations on alteration of physical and chemecal characteristics of night-soils under the semi-continuous experiments are carried out. The followings are results of this experimental study; 1) Diserable digestion time is 15 days in aerobic digestion of night-soil, but the settlement of sludge is bad. 2) In case of 15 days digestion time, 15% of influent quantity is proper as return sludge rate, but in the case, the settlement of sludge is also bad. 3) In the case of 15 days digestion time and 15% return sludge rate (1) Between 5 and 10 days, PH attained the peak. After the peak, PH is decreased gradually. (2) The range of PH is about 7.20 to 8.55. Therefore, management of PH is not needed. (3) Most of all BOD is remved within 5 days. (4) The removal of nitrogen is excellent. 4) When night-soil is treated by aerobic digestion process, study on adeqate dillution rate is requird because BOD of night-soil is very high in Korea.

With a specially designed electrochemical cell, the changes in impedance behavior for Inconel 600 and aluminide diffusion coatings under molten sulfate film with thermal cycles (from 800 ˚C to 350 ˚C) were monitored with electrochemical impedance measurements. It was found that corrosion resistance for both materials increased with lower temperatures. At the same time, the state of molten salt was also monitored successfully by measuring the changes in impedance at high frequency, which generally represents the resistance of molten salt itself. After two thermal cycles, both Inconel 600 and aluminide diffusion coatings showed excellent corrosion resistance. The results from SEM observation and EDS analysis correlated well with the results obtained by electrochemical impedance measurements. It is concluded that electrochemical impedance is very useful for monitoring the corrosion resistance of materials under molten salt film conditions even with thermal cycles.

수년전부터 시작된 물류에 대한 관심은 최근 물류를 구성하고 있는 요소들에 대한 관심으로 다양하고 깊이 있게 발전하고 있다. 초기의 물류에 대한 관심이 전체적인 물류과정에 대한 연 구에 집중되어 있었다면, 최근에는 이를 구성하고 있는 운송, 물류, 유통 등으로 분화시켜 연구 하는 특징을 보이고 있다. 이러한 요소들 중에 하나가 바로 집적화의 문제이다. 물류의 효율성을 최대화하기 위한 방법의 하나로 지역별 최적산업을 적용한 것이 바로 산업단지의 개념이다. 그 동안 산업단지는 지역별로 가장 적절한 산업과 연계하여 효율성을 추구하며 진행되어왔으 며, 이에 따라 학계에서도 관련 연구들이 활발하게 진행되어왔다. 그러나 그 동안의 연구들이 산업단지의 필요성, 활성화, 연계들에 대한 연구들이 주를 이루고 있어, 변화하는 산업단지의 노후화와 개별 기업에 대한 발전 방안 제시가 부족한 것이 사실이다. 본 연구는 그 동안 산업 단지 중심의 발전전략이 기업 중심 발전전략으로 이동해야하는 근거와 방향에 대해 논의하고 자 하며, 관련하여 산업단지 유형별로 그 동안의 성과 추이를 살펴봄으로써 각각 단지들의 특 성과 성과를 파악하고자 한다. 더불어 향후 산업단지의 방향성에 대해 제시하였다. 산업단지 입주가 경쟁력이었던 한계에서 벗어나 산업단지가 나아가야할 방향성에 대해 기존 의 매출액, 고용정도, 수출액, 기업 가동률, 그리고 생산액이라는 고정된 목표에서 벗어나야 함을 나타내었다. 기업이 추구하는 사업의 특성별 입지결정요인이 달라짐을 감안하여 산업단 지의 일률적인 기업 편성의 문제점을 앞으로 개선해야한다. 더불어 산업단지 중심의 발전방안 이 최근변화에 적응하지 못하고 있다는 사실을 인지하여, 지역이나 제품에 적합한 산업단지 기업의 성과 영향요인의 변화를 추구해야 할 것이다. Purpose : By looking at the performance trends for each type of industrial complex, we want to understand the characteristics and performance of each complex. In addition, I would like to present the direction of future industrial parks. Research design, data, methodology : A one-way analysis of variance (ANOVA) was conducted to see if there were any differences in export changes, employment changes, designated area growth rates, and production value changes depending on the country, general, urban high-tech, and agricultural industries. Results : According to the analysis of differences in export changes, employment changes, designated area growth rates, and production value changes according to the country, general, urban high-tech, and agricultural industry, each group showed significant differences in export changes, employment changes, designated area growth rates, and production value changes. Conclusions : It expressed that the entry of industrial complexes should be outside the limits that used to act as competitiveness, and that internal and external factors should be applied to fit the resources and characteristics of the company, not just to move into local industrial complexes.

노랑초파리종군의 발생단계에 따른 단백질의 변화와 유전적 유연관계 : SDA - PAGE 에 의한 수용성 단백질의 분석 Analysis of Soluble Protein by SDS - PAGE

이택준,홍경자,송은숙 한국유전학회 1993 Genes & Genomics Vol.15 No.4

Soluble protein in eight species of the Drosophila melanogaster species group was analyzed by SDS-PAGE in order to investigate protein variations and genetic relationships among the eight species in the three developmental stages of larva, pupa and adult. From the comparison of scanning patterns on the electrophoretic phase by densitometer, three developmental stages showed qualitative and quantitative differences in respective species. In the comparison between species, genetic similarity among the eight species for three stages was calculated by band counting method(Ferguson, 1980). Based on the data of genetic similarity, the biochemical dendrograms in the eight species were constructed. In three developmental stages of 3rd instar larva, pupa, adult, the dendrograms showed same patterns. According to the results, the eight species could be devided into two phyletic groups, one comprises the D. melanogaster, D. simulans, D. lutescens and D. suzukii, while the other includes D. auraria, D. biauraria, D. triauraria and D. rufa. SDS-PAGE proved to be useful in systematics at the stages of larva and pupa as well as adult, although the magnitude of genetic differentiation may be different among the three developmental stages.

The objective of this study was to improve properties of plasma sprayed HAp layer to titanium substrate by introducing an intermediate layer with two different methods. Before applying Zn doped HAp coating on titanium substrate, an intermediate layer was introduced by titanium plasma spray or titanium anodization. Heat treatments were conducted for some samples after titanium intermediate layer was formed. Zn doped HAp top layer was applied by plasma spraying. Three-point bending test and pull-off adhesion test were performed to determine the adhesion of Zn doped HAp coatings to substrates. Long-term credibility of Zn doped HAp plasma sprayed coatings on titanium was assessed by electrochemical impedance measurements in Hanks’ solution. It was found that both titanium plasma sprayed and titanium anodized intermediate layer had excellent credibility. Strong adhesion to the titanium substrate was confirmed after 12 weeks of immersion for coating samples with titanium plasma sprayed intermediate layer. Samples with titanium anodized intermediate layer showed good bending strength. However, they showed relatively poor resistance against pulling off. The thickness of titanium anodized intermediate layer can be controlled much more precisely than that of plasma sprayed one, which is important for practical application.
