This study was conducted to find out the effects of rainfall occurring during the paddy sun-during process of traditional paddy harvesting operations on the quality of milld rice. Rice varieties used for the experiment were MINEHIJARI variety a japonica and SUWEON 264 vareity , a sister-line of TONG-IL . Sun-drying days after the paddy cutting, times of storm occurrance during sun-drying period, and storm duration were treated as variables. The results is summarised as follows : 1. Brown rice recovery exposed to rainfall during the sun-druing period were ranged 81.6-82.1% and 79.4-80.2% for MINEHIKARI and SUWEON 264 varieties, respectively. which showed negligible effect by rainfall. 2. Milling recovery of MINEHIKARI variety was not affected by storm duration but by the by the sun-drying days after cutting as the sun-drying days increased to eight and four days when the variety met the rainfall one and two times, respectively. The range of milling recoveries of MINEHIKARI variety were 75.18-74.07% and 75.24-73.46% as the variety met the rainfall one and two times, respectively, and it were estimated that up to 0.9% and 1.5% of milling recovery would be reduced by one and two times of rainfall during sun-drying period. 3. The milling recovery of SUWEON 264 variety was affected only by the increase of drying days after cutting when it met one time of rainfall during the sun-drying period, while it was begun to reduce by the storm duration more than 11hours as the drying paddy met two times of rainfall. The milling reveries of the paddy met one and two times of rainfall were ranged 74.24-73.21% and 74.02-72.36% which were estimated to be reduced up to 0.9 % and 1.8% by the increase of the drying days after cutting and storm duration , respectively. 4. The head rice recovery of MINEHIKARI rice variety showed notable decrease as the drying days after cutting increased, and also it was greatly reduced even by the five hours of storm duration when one time of rainfall occurred but it was not affected by storm duration when the rainfall occurred two times. Head rice recoveries of MINEHIKARI met one and two times of rainfall during the sun-drying period were 65. 15 -40.85% and 61.86 - 30.03 %, which showed terrible reduction as much as up to 25% and 35% compared to that which did not met rainfall during the sun-drying process. 5. Head rice recovery or SUWEON 264 variety was very much reduced as the sum-drying days after cutting increased. Storm duration less than five hours during the sun-drying process did not affect on the decrease of head rice recovery when the variety was exposed to one time of rainfall, while storm duration affected considerably on the reduction of head rice recovery of SUWEON 264 variety exposed to two times of rainfall. The range of head rice recovery, 56.43 - 33.94% and 51.28 - 21.03% , for the paddy exposed to rainfall one and two times were evaluated that up to 24% and 37% of reduction in head rice recovery would be brought about compared to the head rice recovery of the sundriedpaddy that did not met the rainfall.

Objective : The effects of electroacupuncture(EA) stimulation on heart rate variability(HRV) for healthy adults are investigated with power spectrum analysis(PSA) of HRV. Methods : The HRVs of every 10 minute for 22 healthy volunteers(13 men and 9 women) were measured for an hour with SA-3000P(Medicore Co., Ltd., Korea). The median age with arithmetic range of 13 men and 9 women was 26.00 years with 22.75~27.00 years. The initial 20 minutes were defined as baseline period(pre-EA period), the following 20 minutes as the EA period and the last 20 minutes as the post-EA period. In each EA periods, volunteers received EA(2Hz, 0.6~0.8ms duration, maximal tolerated stimulation without discomfort) on the right Zusanli(ST36), Shangjuxu(ST37) acupoints while supine, resting. Results : Heart rate of volunteers at post-EA period was significantly decreased compare to that of pre-EA period, while SDNN at post-EA period was significantly increased. Heart rate at EA period was significantly decreased compare to that of pre-EA period, but Ln(LF) and LF/HF at EA period were significantly increased. Ln(HF) at post-EA period was significantly decreased compare to that of EA period, while the other variables were not significantly changed. Conclusions : The results suggest that EA in healthy adults is associated with changed activity in the sympathetic and parasympathetic nervous system. Further study is needed for investigating the effects of EA on HRV and autonomic nervous system.

Purpose: Neuroendocrine carcinomas of the stomach account for only about $0.3\%$ of all gastric tumors. The prognosis of this disease is very poor compared with the common type of gastric adenocarcinoma. The purpose of this retrospective study was to review the clinicopathologic features of 18 cases of this unusual gastric tumor and to establish a treatment strategy for this tumor. Materials and Methods: Excluding 2 cases of non-curative resection and 1 case of operative mortality, 18 cases of typical neuroendocrine carcinoma who had curative resection from January 1991 to December 2000 at Asan Medical Center were analyzed; 6841 gastric cancer patient were treated surgically during the same period. Results: The mean age at the time of diagnosis was 58.6 years (range: $35\∼75$ yr). Sixteen patients were male, and two were female. Eleven tumors ($61.1\%$) developed in the lower part of the stomach, three ($16.7\%$) in the middle part, and three ($16.7\%$) in the upper part. One tumor involved the entire stomach. Eight cases ($44.4\%$) were Borrmann type 2, and six case ($33.3\%$) were Borrmann type 3. The mean tumor size was 6.94 cm (range: $0.6\∼15$ cm). Nine cases ($50\%$) showed recurrence of the disease, and eight of them died within 20 months. Of the nine recurred cases, 7 cases ($77.8\%$) showed liver metastasis. The mean disease-free interval was 6.8 months (range: $2.5\∼11$ months) after surgical resection, and the mean survival was 17.9 months (range: $8\∼40$ months) for recurrence cases. One patient with liver metastasis was treated with a liver-wedge resection just after diagnosis and was still alive for 37.5 months postoperatively. There were 9 deaths after the median follow- up period of 40 months (range: $8\∼72$ months). Conclusion: Gastric neuroendocrine carcinomas frequently recur at the liver, even in early stage cancer, and have a poor prognosis. We experienced a case of successful control of hepatic metastasis by surgical resection and a case of a small cell carcinoma which was successfully controlled with systemic chemotherapy.

Background: The aim of this study was to assess the epidemiological and clinicopathological characteristics of primary extranodal non-Hodgkin's lymphoma (pENL) patients, focusing on treatment and survival outcome. Materials and Methods: Between October 2003 and March 2012, 802 patients with non-Hodgkin's lymphoma (NHL) were diagnosed and treated in two different cancer centers of Southern Turkey. Results: pENL, constituted 12.4% (100/802) of all NHL studied during this period. Median age of the patients was 56 years (range 17-87 years) and the male: female distribution was 3:2. Eighty-five of 100 patients (85%) were in stage I/II, 9/100 (9%) in stage III, whereas 6/100 (6%) were in stage IV. Head and neck constituted the most common site (51/100, 51%), followed by gastrointestinal tract (GIL) (37/100, 37%), and cerebrum (CL) (5/100, 5%). Diffuse large B cell lymphoma (DLBCL) was the most common histological type, observed in 53% of patients, followed by marginal zone extranodal lymphoma (13%). Most of patients (76%) received a CHOP containing regimen. Complete remission (CR) were achieved in 71% of patients. The median follow-up duration of all patients was reported as 37.6 months (range, 0.8-165 months). This period was reported as 137.5 months (range, 117.5-1578.6 months) in gastrointestinal lymphoma (GIL) patients, 119.0 months (range, 91.8-146.1 months) in head and neck lymphoma (HNL) patients, and 18.4 months (range, 12.6-24.1 months) in cerebral lymphoma (CL) patients. Conclusions: Head and neck, and the gastrointestinal tract were the two most common extranodal sites observed. Histologically DLBC accounted for the majority of cases. Most patients were on earlier stages, had low-low intermediate IPI scores and had a favorable prognosis.

Purpose: To report the clinical outcomes and complications of flexor hallucis longus (FHL) tendoscopy using 3 portals. Materials and Methods: Between January 2012 and April 2013, 10 patients (10 ankles) received tendoscopic surgery for the treatment of FHL tenosynovitis. Patients complaining of pain and tenderness along the course of FHL despite over 6 months of conservative treatments were indicated for surgery. The mean age was 41.7 years (range: 18-57) and the follow up period was 12.7 months (range: 6-20). Tendoscopy was performed using posteromedial, posterolateral, and plantar portals. Clinical evaluations included preoperative and postoperative visual analogue scale (VAS), American orthopaedic foot and ankle society (AOFAS) score, and patients' satisfaction. Results: Tendoscopic findings included tenosynovitis in 10 cases, degenerated vinculae in 6 cases, stenosis of the tendon at its entrance into the fibro-osseous tunnel in 5 cases, and degenerative partial tendon tear in 3 cases. Two cases had associated symptomatic os trigonum and 3 cases had posterior ankle impingement syndrome. Preoperative pain decreased from median VAS 6 (range: 4-10) to 2.1 (range: 1-5) at the last follow up and AOFAS score improved from 50.1 (range: 36-63) to 82.1 (range: 61-89) (p<0.05). Nine patients were satisfied or very satisfied with the outcome. Injury of the lateral plantar nerve occurred in one case. Conclusion: FHL tendoscopy using 3 portals is a feasible and useful minimal invasive surgical technique for the management of FHL tenosynovitis.

The current study analyzed the home range size of the Common Kestrel (Falco tinnunculus) by observation using the natural markings in the suburban area of Busan from December 2009 to May 2010. In all, 26 individual kestrels were observed in the study area, of which 14 individual kestrels were frequently observed (more than five times) and 12 were observed less frequently (less than five times). Mean home range sizes of the 14 frequently observed kestrels were estimated using two different methods (minimum convex polygon (MCP) method and fixed kernel (FK) method): 34.49 ha(2.74-163.96 ha) by 100% MCP, 41.35 ha(3.54-99.02 ha) by the 95% FK, 14.33 ha(0.20-31.57 ha) by the 75% FK and 5.75 ha(0.52-14.74 ha) by the 50% FK. The mean home range size was larger for males than for females estimated at 51.50 ha(15.04-163.96 ha) and 11.80ha(2.74-24.48 ha), respectively, by the 100 % MCP method and 8.02 ha(2.38-14.74 ha) and 2.72 ha (0.52-4.28 ha), respectively, by the 50 % Fixed Kernel method. The home range sizes by sexes in breeding pairs differed during the wintering and breeding seasons; the sizes decreased among females but increased among males during the breeding season. Such differences of home range sizes between sexes could be attributed to parental role division during the breeding season. Females stay in the nest or next to it during laying, incubating, and feeding activities, and males go far away from their nest sites to forage areas for their fledglings for most of the breeding period.
