The purpose of this study was to evaluate clinical characteristics and treatment outcome of patients with head and neck squamous cell carcinoma of unknown primary (HNSCCUP), treated according to the method of our hospital. Six patients with histopathologically and radiologically confirmed HNSCCUP January 2010-December 2016 were enrolled in this study. All patients underwent radical neck dissection involving level I-V, bilateral tonsillectomy, and diagnostic esophagoscopy and postoperative radiotherapy (RT), with or without concurrent chemotherapy. There were no major complications resulting from surgical intervention. Duration of follow-up was 56.3±20.2 months (range, 28-82 months). There was no recurrence or late detection of primary site of HNSCCUP. All patients with HNSCCUP except one were alive, at the time of the last follow-up. The other patient had no recurrence of HNSCCUP, but died of colon cancer at 58 months postoperatively. We have successfully treated patients with HNSCCUP by performing radical neck dissection, bilateral tonsillectomy, and diagnostic esophagoscopy and postoperative RT with concurrent chemotherapy, and recommend using this method as the main treatment method.

It is widely recognized that exhaust emissions,fuel economy and engine torque are affected by the coolant temperature of the engine, and logic would suggest that a cooling system offering a better compromise of coolant temperature of the engine would improve both overall engine power and economy. Coolant temperature and intake air temperature near cooling parts is measured CAMS(Computer Aided Measuring System) with K-type thermocouple and A/D converter.

本 硏究는 演習林內 造林樹種의 成長過程과 一般收穫表上의 成長過程을 比較하여 演習林經營合理化를 위한 基礎資料로 提供하고자 실시하였다. 演習林內 6個小班에서 3個樹種의 標準本으로 選定하였으며 樹幹析解를 通하여 分析한 結果는 다음과 같다. 1) 樹高成長은 25年을 基準으로 할 때 일본잎갈나무, 리기다소나무, 잣나무의 順位였다. 2) 直俓成長은 25年을 基準으로 할 때 일본잎갈나무, 잣나무, 리기다소나무, 잣나무의 順位였다. 3) 材積成長은 일본잎갈나무, 잣나무, 리기다소나무의 順位로 樹高成長보다 直俓成長에 더 影響을 받는다. 4) 演習林內 造林 樹種의 成長이 一般收穫表에 比較에 不良한 成長을 보이고 있다. 5) 成長率에서는 初期成長率은 一般收穫表上과 對等하거나 높은 傾向을 나타내나 樹齡이 增加함에 따라 減少하는 것을 계속적인 推育管理에 疏忽에 起因한다. This study was carried to compare the growth of silvicultural species in the university forest with those of general yield table prepared for the entire country and to afford data for the rationalization of university forest management. The growth researches were made at six subcompartments through stem analysis, and the results obtained in this study were as follows; 1) The height growth on the basis of 25 ages in Larix leptolepis was found the best, and those of Pinus rigida Pinus koraiensis in order. 2) The diameter growth on the basis 25 ages it Larix leptolepis was found the best, and those of Pinus koraiensis Pinus rigida in order. 3) The volume growth Larix leptolepis was found the best, and those of Pinus karalensis Pinus in order, it is affected more the diameter growth than the height growth. 4) The growth of the silvicultural species in the university forest was poor as compared with those of the general yield table. 5) In the growth rate, the silvicultural species in the university forest was higher at the early stage, but as the age progressed the growth rate was radically decreased, was lower than the general yield table. It is to tending-carelessness.

This study was carried out to verify the Nature and Role on the Forest Association in Korea through Historical fact, Theoretical background, and Analysis of the Association's business. the results were summarized as follows : 1. The Forest Association have both the Nature of agency group for National forest resource policies and of Cooperative Association for profit of the union's member. 2. The Forest Association have to be emphasized on the Nature of the local union over the Nature of the functional union. 3. The Forest Association have to be forstered from a point of view Local Forestry Capital. 4. The Forest Association have to be become independent through the variety of economic business. And it's independence have to be supported with the systematical and legal security. 5. In order to accomplish these roles would be taken a decisive support from the Government and carried out it's effort of the Forest Association.
