This study examined cut slope reinforcement cases in the Pusan-Kyoungnam district, which includes 3 Pusan, 2 East Kyoungnam, 6 Middle Kyoungnam and 3 West Kyoungnam cases. It also analyzed the causes of the collapse and hazards, and the reinforcement method that had been used. The conclusions of the study are presented in the following. (1) The major causes of collapse and hazards in the cut slope are in the following. (ⅰ) The rise of ground water due to a local downpour and the ground seepage of water. (ⅱ) Existence of a soft ground layer. (ⅲ) A decision of slope inclination by an empirical method. (2) It turned out that the main reinforcement methods used for each cut slope were the remethod of gentle slope inclination and the retaining wall method. The auxiliary methods were drainage method for the prevention of water seepage and protection method of surface for the prevention of surface erosion. These methods were applied to almost all the slopes.

This thesis studied an allowable error range of construction distance between piles, Our experiment has altered the distance between piles in various ways to observe characteristics of the piles bearing capacity according to the changes. It was observed that the range of changes in the piles bearing capacity was insignificant when the distance between piles were great, where as the range became greater inversely to the distance between piles. The pulling resistance exceeded the allowable range when the distance between piles was less than 2.0D. It turned out that the allowable error range of construction was 1.0D for the field of our interest.

Purpose: By the definition of UICC TNM classification (fifth edition), the nodal stage of gastric cancer is based on the number of metastatic lymph nodes, which is influenced by the number of resected lymph nodes. And individual differences in the number of resected lymph nodes had been observed in patients with gastric cancer. The aim of this study is to verify the factors which are associated with the difference in the number of resected lymph nodes in patients with gastric cancer. Methods: We reviewed 613 patients with gastric cancer who underwent curative resection and D2 lymph node dissection with 15 or more resected lymph nodes. The number of resected lymph nodes was analyzed according to the characteristics of patients, the types of operation and prognostic factors of gastric cancer. Results: The mean number of resected lymph nodes per patient was 33.0 (median: 31.0, range: 15-88). The number of resected lymph nodes was significantly associated with the types of operation, the location and size of tumor, macroscopic types, depth of tumor invasion and the number of metastatic lymph nodes. Patient's age, gender and the histopathological finding's had no relationship with the number of resected lymph nodes. Conclusions: The number of resected lymph nodes from gastric cancer was different in each patient despite of same D2 lymph node dissection and it was associated with several prognostic factors of gastric cancer.

This study aims to find out the individual and structural variables in the determination of the wages of the sports center staffs, to analyze the precedent factors of the wage satisfaction(variables of job inputs, the variables of job characteristics, the comparisons with the objects compared, the variables of the organization characteristics), and to examine the effects of the wage satisfaction(welfare programs, the levels of wages, the increase of wages, the management of wages) on the indexes of the organization efficiency such as the will to leave jobs, the outcomes of jobs, the organizational committment and so on. The materials were analyzed by using the programs of SPSS/PC+11.0 and LISREL 8.30 by means of the covariance structure analysis. The results of the inspection of the hypotheses through these methods of the study and the analyses of the materials are as follows: First, the results of the comparative analyses of the satisfaction in respect to the individual and structural variables show that females, the older groups, and the married groups have higher satisfaction than males, the younger groups and the unmarried groups. And the higher positions produce higher wage satisfaction. The higher schooling and the longer careers produce lower wage satisfaction, whereas, in terms of the salary management, they show higher satisfaction. In terms of the experiences of leaving jobs, the groups with no such experiences show high wage satisfaction, and the groups with experiences of leaving jobs two times show the lowest satisfaction. In terms of the methods to join the companies, the groups scouted show the highest wage satisfaction and the groups employed by public examinations show the lowest wage satisfaction. Second, the analyses of the precedent factors affecting the wage satisfaction show that the higher awareness of the job inputs, the job characteristics, and the comparison factors with the groups compared show the less satisfaction with the levels of wages. And the higher awareness of the factors of the organizational characteristics show the higher satisfaction. The analyses of the effects of the wage satisfaction on the organizational efficiency show that the higher wage satisfaction has a negative relation with the will to leave jobs, and a positive relation with the outcomes of jobs and the organizational committment.

유암종은 전신에 퍼져 잇는 장크롬친화성 세포에서 기원하는데 위의 유암종은 비교적 드문 질환으로 모든 유암종의 1.9~2.2%에 해당하며 위에 발생하는 종양의 1% 미만에서 보고되고 있다. 유암종은 일반적으로 증상이 비특이적이고 면역조직화학검사에 의해서 진단되기 때문에 과거에는 드물게 발견되었으나 최근 내시경 기기 및 술기의 발전과 검사 빈도의 증가 및 면역조직화학검사의 발달로 진단율이 증가 추세에 있으며, 드물지만 유암종에서 선암과 공존하는 예들이 보고되고 있다. 저자들은 심와부 동통을 주소로 내원한 70세 남자 환자의 상부위장관내시경 검사에서 위체상부의 대만곡에서 0.4×0.4 cm 크기의 중간 함몰을 가진 Yamada 1형의 용종과 함께 전정부의 전벽에서 0.8×0.5 cm 크기의 융기된 점막 소견을 보여 조직학적으로 각각 위유암종 및 위선종임을 확진한 후 내시경적 용종 절제술로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Carcinoid tumors are arisen from enterochromaffin cells, which are scattered throughout the body. These tumors are composed of variable numbers of cells that contain endocrine granules in their cytoplasm, which can be identified by immunohistochemistry and electron microscopy. Gastric carcinoid tumors are relatively rare tumor, the reported incidence being 1.9~2.2% of all carcinoid tumors and less than 1% of all gastric tumors. Sometimes, composite carcinoid tumors and adenocarcinoma is reported. We experienced a case of the coincidence of carcinoid tumor and adenoma at the other site of the stomach in a 70 year old male patient. Gastrofiberscope showed 0.4×0.4 cm sized Yamada type I polyp with central depression on the greater curvature of the proximal body and 0.8×0.5 cm sized focal slightly elevated mucosa on the anterior wall of the antrum. The endoscopic biopsy specimens revealed carcinoid tumor and tubular adenoma with moderate atypism, respectively. The carcinoid tumor and adenoma were removed by endoscopic polypectomy. According to the follow-up gastrofiberoscopy after 7 month later, both lesions were nearly normal mucosa except whitish atrophic change after polypectomy.

Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.

In this paper an efficient method for detection of dominant points using run-length codes is proposed. In order to analysis and recognition of binary images, dominant points of region boundaries are very important. Several special runs are introduced for run-length coding, and an binary image is represented by the special runs. Each special run includes its run property. The proposed method can be obtained chain codes and dominant points, simultaneously, and it is simulated using several binary images. By computer simulation, the proposed method can be used to detect dominant points in boundaries.
