Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

Primary retroperitoneal mucinous cystadenocarcinoma is a very rare malignancy, and little is known concerning its Pathogenesis, optimal treatment, and prognosis. A 29-year-o1d pregnant woman (21 weeks) Presented with abdominal discomfort CA 19-9, CA 125, and CEA were normal Abdominal CT scanning revealed a 19x15x13 cm retropentoneal tumor Exploratory laparotomy and tumor excision were performed. Mucinous retropentoneal implants were removed as completely as possible Histologically, the tumor showed focal areas of capsular invasion, but free resection margins The uterus and both ovaries were normal in appearance No adjuvant therapy was pursued. Six months later, Peritoneal and bilateral ovarian metastases were discovered. Hence, we report the details of this case of primary retroperitoneal mucinous Cystadeno-carcinoma and present a review of the literature.

The wireless sensor network consists of a number of sensor nodes which have physical constraints. Each sensor node senses surrounding environments and sends the sensed information to Sink. The inherent vulnerability in security of the sensor nodes has promoted the needs for the light weight security protocol. In this paper, we propose a non-hierarchical sensor network and a security protocol that is suitable for monitoring the man-made objects such as bridges. Furthermore, we present the efficient way of setting the routing path by storing IDs, MAC(message authentication code) and the location information of the nodes, and taking advantage of the two node states, Sleep and Awake. This also will result in the reduced energy consuming rate.

Objective: This study was performed to examine the relationship between community-based social support and psychosocial distress in workers. Methods: The study subjects were 596 workers recruited from 11 companies in Chungju city. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, job stress, work-based social support, community-based social support and level of psychosocial distress. Results: Hierarchical multiple regression analysis showed that workers with no chronic disease, exercise and sufficient sleep had a higher score of psychosocial distress than those with chronic disease, no exercise, and not enough sleep. Coworker's work-based social support and community-based social support were negatively associated with psychosocial distress. The R square value of total independent variables on psychosocial distress was 0.409, and that of community-based social support on psychosocial distress was 0.052. Conclusion: This study showed that community-based social support served as a protective factor against psychosocial distress in some workers. We recommend the establishment of a worksite stress reduction program in occupational level as well as community-based social support.

The ν_6 band of the ethane gas molecule was theoretically synthesized. The intensity and the frequency of each rotational line were computed with VAX-11 computer. The theoretically synthesized spectrum was compared with the experimentally obtained spectrum, which was taken through FT-IR spectrophotometer MX-3600. The R and P branches of the ν_6 band contour of the ethane gas molecule were different from the regular symmetrie top molecule and rather similar to the linear molecules as if there were no K dependence. The absorbance of the P-branch spectrum was overlapped by the unknown branches of the neighbour bands The intensities and frequencies of the unknown lines were not indentified. The overall band contour of the observed spectrum was quite well coincided with the theoretical spectrum except the P-branch.

This study was conducted to evaluate blood pressure associated with body mass index and blood lipids. Study subjects were 3,076 persons (1,623 males and 1,453 females) who visited to General Health Screening Center located in Chonan. Data were collected from 2001 to 2003. Height, weight and blood pressure were measured by a trained nurse. The level of total cholesterol, HDL cholesterol, triglyceride, and fasting blood sugar were selected as biometric test variables. Statistical analysis, such as t-test, simple correlation, and stepwise multiple regression were performed using SAS package program. The mean (standar deviation) of age, BMI, systolic blood pressure, diastolic blood pressure, fasting blood sugar, triglyceride, total cholesterol, HDL cholesterol, and LDL cholesterol in study subjects were 48.4 ±11.8 years, 23,7 ± 3.2 kg/m^(2), 124.6 ± 16.3 mmHg, 80.9 ± 10.7 mmHg, 97.6 ± 24.9 mg/㎗, 154.4 ± 105.6 mg/㎗, 203.2 ± 39.2 mg/㎗, 51.0 ± 12.8 mg/㎗, and 121.8 ± 35.6 mg/㎗, respectively. In multiple regression analysis of BMI and blood lipids on systolic blood pressure after controlling for confounders (age, sex, and fasting blood sugar), BMI, HDL cholesterol, and triglyceride were found to be significant positive independent predictors of systolic blood pressure. In multiple regression analysis of BMI and blood lipids on systolic blood pressure after controlling for confounders (age, sex, and fasting blood sugar), BMI, triglyceride, HDL cholesterol, and LDL cholesterol were found to be significant positive independent predictors fo systolic blood pressure. With above results, it was found that BMI and blood lipids were significantly associated with blood pressure.

비만은 동맥경화의 위험인자로서 혈중에 triglyceride의 농도를 종가시키고, 상대적으로 HDL-Cholesterol의 농도를 감소시킴과 동시에 수축기 혈압을 상승시킨다. 본 연구에서 홍삼제품류를 4년 또는 5년 동안 복용해 온 건강한 사람 (ginseng군)과 홍삼제품을 복용하지 않은 건강한 사람 (control군)을 대상으로 하여 신체 계측치로부터 비만지수를 구하고 이것과 혈중의 triglyceride (TG)농도, TG/HDL-Cholesterol ratio 및 수축기 혈압과의 상호관계를 연구한 바, ginseng군에서는 대조군에 비해 혈중의 TG 농도가 일정하게 유지되었고, TG/HDL-Cholesterol ratio 및 수축기 혈압도 일정하게 유지되었다. 이러한 현상은 ginseng군에서 기호품으로 alcohol을 섭취하거나, 흡연을 한 경우에도 상관없이 일정하게 유지 되었다. 이 결과는 홍삼제품류를 장기 복용하면 비만의 저하 및 고혈압 또는 동맥경화의 위험인자가 억제될 수 있고, 결론적으로 비만, 고혈압 및 동맥경화를 예방할 수 있을 것으로 추정한다. Obesity is the risk fcactor of atherosclerosis and not only increases triglyceride concentration in blood but also decreases relatively the ratio of TG to HDL-Cholesterol in blood. In case of obesity, systolic blood pressure is also increased in responding the increase of TG in blood. Index of obesity in red ginseng-taking group (ginseng group) was lower as compared with non-red ginseng-taking group (control group). The TG concentration, the ratio of triglyceride to HDL-cholesterol in blood and systolic blood pressure were decreased in the subjects of ginseng group compared with that in control group. It is inferred that long-term intake of ginseng products may help to prevent the risk of atherosclerosis and obesity.

This study aims of identifying the historical development trace and classifying the characters of spa-resorts(20 cases) since 1876 untll the modern era in Korea. The main findings of this study, on the historical development trace and the transition changes of the economic, social situation and the rise and fall of spa utilization, are the classification of the 4 epochs, consisting of 5 periods; (i)Korean traditional utilization spas (ii) Japanese utilization and development spa (iii) Post-Liberation-stagnant period (iv) Revival of spas utilization (v)Active development period. Following these, 3 primary factors ; (a) Favorable Locations (b) Utilization spheres (c) Activities Facilities; are identified, and divided into 16 categories. The quantitative analyses findings on the 16 categories, are the 4type of formation (A, B, C, D). Subsequently, major of the spas start off, are of the A and D type, while the changes from type A to B are also found.
