This study used the finite element method analysis to estimate enforced replacement shapes and replacement depth. The data were expected to be used as the fundamental data of the design through the comparison with the results of the elastic wave exploration and investigation. The results of the research are summarized in the following. (1) After dividing the breakwater into 5models, on which elastic wave exploration was performed, the enforced replacement shape has been obtained by the finite element method. The result was satisfactory compared to the results of the elastic wave exploration. (2) The enforced replacement shapes of the breakwater were compared in different ways; in the design, in the elastic wave exploration in field and in this study. While the enforced replacement shape in the design is substantially different from that in elastic wave exploration in field, it turned out to be similar to the results of this research. (3)If an enforced replacement shape is standardized in configuration of breakwater, depth of soft soil and th value of soil property, it can be used as the standardized section in designing breakwaters.

To find the prevalence and related factors of low back pain experienced by some beauticians. a survey was made toward 252 beauticians in Kwangju City from March 1st to April 1st, 1998. The results were as follows; 1. The prevalence rate of low back pain among the respondents for the last week was 59.5%. 2. The aid group and staff group with low back Pain had significantly longer duration of work than those without low back pain. Managers who had bad posture with twisted or too much extended back showed a significantly higher prevalence of low back pain than those with good posture during work(P<05). 3. Aid group with low back pain showed significantly higher points at total stress score, depression score, general health score and vitality score than those without low back Pain. The staff group with low back pain showed significantly higher points for total stress score, sleep disorder and anxiety score, depression score, general well-being and vitality score than those without low back pain. Managers with low back Pain showed significantly higher points of stress at social performance and self confidence (P<05) than those without low back pain. The above results suggest that low back pain is related to different jobs and work environments for beauticians. So effective measures and further studies against risk factors must be made considering their jobs. To prevent or reduce low back pain, appropriate management of stress for beauticians is necessary.

An inflammatory difference between the gastric antrum, body and fundus was studied in 39 H.pylroi positive duodenal ulcer and 29 H. pylori chronic gastritis patients. Also we studied correlation of H. pylori colony count and inflammatory severity. Patients with newly diagnosed duodenal ulcer and chronic gastritis were endoscoped and two biopsy secimens each taken from the antrum, body and fundus. Although intestinal metaplasia in antrum and inflammatory activity in fundus were more severe in chronic gastritis patients. another inflammatory difference was equally likely to be found between two groups. There was no definite histological inflammatory difference between duodenal ulcer and chronic gastritis patients. A positive correlation was found between the number of H. pylori and the severity of inflammation.

진행성 골화성 섬유 이형성증은 2 백만명 중에 1명 발생하는 매우 드문 유전질환이다. 저자들은 2차례의 외상후 심해진 진행성 섬유 이형성증환자에서 최근 다시 발생된 외상후 생긴 병변부위에 biphosphonate와 steroid 투여로 최근수상부위의 근육 골화와 경화를 현저한 호전을 보였으나, 기존의 골화가 이미 진행된 병변에서는 잘 반응하지 않음을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Fibrodysplasia ossificans progressiva(FOP) is an extremely rare hereditary disorder characterised by progressive heterotopic ossification of the soft tissue. The resulting progressive immobilization of the limbs, jaw and chest wall generally leads to severe disability. We present an 20-rear-old man with advanced FOP. He had two operative interventions by prior traffic accident and recent biopsy. It resulted abnormal ossification. Treatment for this disorder is avoidance of exacerbating factors and medical strategies is biphosphonate and steroid. We observed the course of ossification and muscle atrophy during biphosphonate and steroid therapy in advanced FOP.

The length of small intestine is about 75% of total gastro-intestinal tract, but the incidence of malignacy is account for 2% of it. Whereas most of small intestinal malignancy is duodenal cancer, and the most common histologic type is adenocarcinoma. Duodenal small cell carcinoma is extremely rare. We had a case of a 66-year-old female who visited the hospital to evaluation for RUQ discomfort. Endoscopy was done and large ulcerative lesion is founded at duodenum. The histologic finding was small cell carcinoma. We performed Abdomen-pelvis CT and bladder wall thickening was seen. For confirm the lesion, cystoscopic biopsy of bladder wall was done and pathologic finding was small cell carcinoma, too. In positron emission tomography-computed tomography (PET-CT), we can find multiple metastasis to duodenum, bladder, lung and brain. Finally we diagnosed duodenal small cell carcinoma with multiple metastasis. After 4-cycles of chemotherpy, Irinotecan and Cisplatin, the mass size was markly decreased. However she was expired due to unknown origin infection. We present a extremly rare case of duodenal small cell caricnoma with bladder wall, lung and brain.

Chemotherapy response related massive bleeding and management

( Ha Yeol Park ),( Choon Hae Chung ),( Chi Young Park ),( Sang Gon Park ) 대한내과학회 2011 대한내과학회 추계학술대회 Vol.2011 No.1

The goals of palliative chemotherapy are to improve overall survival and the quality of life through relief of symptoms.The other hand, chemotherapy has many side effects such as myelosupression, neuropathy, gastro-intestinal symptom and infertility. In many known side effects of chemotherapy, bleeding occurs in approximately 6-10% of patients with advanced cancer. Most of bleeding is local vessel damage and systemic process such as disseminatated intravascular coagulopathy, abnormalities in platelet function or number after chemotherapy. There is no article about chemotherapy response related bleeding. However, bleeding may occur in chemo-sensitive tumor like lymphoma and in pre radiotherapy patient such as head and neck cancer, rectal cancer after chemotherapy. There are three cases of pure chemotherapy response related bleeding without other bleeding condition. One is pre-radiotherapy given maxillary sinus cancer, another is chemo sensitive gastric cancer and the last case is pre-radiotherapy given rectal cancer. These all cases had a massive bleeding after chemotherapy without other bleeding condition and successful management variable method such as embolization, endoscopy, and thrombotic agent.

Sinmichal is the first waxy wheat variety in Korea. It was developed on the purpose of increasing the added-value byintroducing waxy genes to domestic wheat. It was bred from a cross between Olgeurumil, non-waxy, and a waxy descent of a crossbetween Kanto 107 and Baihuo at the National Crop Experiment Station (NCES) in 1997. It was tested as Suwon 292 in regionaland 5.92 ton/ha, respectively. It was inferior in flour yield to Geurumil, but the ash content was lower than that of Geurumil. Alsoits flour showed soft to semi-hard property based on protein content and sedimentation value. Three distinctive properties were obtainedfrom Rapid Visco-analyzer (RVA) tests of Sinmichal, waxy flour. First, as the temperature of the aqueous slurry of its flour wasoC which was far lowertemperature than the 95oC of other wheats. Secondly, the breakdown viscosity of Sinmichal paste was greater than those of othercomon wheats. Lastly, the final viscosity measured after linearly coling of paste temperature down to 50oC was far lower than that ofnd thecooked products should be remained softer in texture for longer time due to the delayed retrogradation of the gelatinized starch.

Choon-Keun Park,Yong-Seung Lee,Jeoung-Ha Sim,Dong-Choon Ahn 한국실험동물학회 2008 Laboratory Animal Research Vol.24 No.3

To obtain basic data on the miniature pig, we measured the size of the genital organs in five female miniature pigs sacrificed under ketamine anesthesia. The right and left ovaries weighed 5.2±2.2 and 4.5±1.1 g, respectively. The lengths of the genital tract were as follows: uterine tube 182.2±58.8 ㎜, uterine horn 852.0±102.3 ㎜, uterine body 17.1±4.2 ㎜, uterine cervix 89.0±15.1 ㎜, vagina 91.6±9.3 ㎜, and vaginal vestibule 46.4±2.5 ㎜. The diameters of the genital tract were as follows: ampulla of the uterine tube 7.1±0.7 ㎜, isthmus of the uterine tube 3.8±0.5 ㎜, uterine horn 22.1±2.6 mm, thin cranial portion of the cervix 16.6±1.4 ㎜, thick caudal portion of the cervix 26.0±1.6 ㎜, vagina 16.7±2.9 ㎜, and vestibule of vagina 19.9±2.3 ㎜. We found 3.8±1.1 large cervical pulvini and 6.6±1.7 small ones. The pulvini formed 6.6±1.5 folds, and the pudendal cleft was 18.8±3.5 ㎜ long. These results may be helpful in developing the screw type artificial insemination instruments and in comparing data on commercial sows.
