Effects of intracerebroventricular captopril on the central pressor response to bradykinin were examined in normotensive and 2-kidney, 1 clip (2KIC) Goldblatt hypertensive rats. The experiment was done under pentobarbital (50 ㎎/㎏. IP) anesthesia. Captopril (1 ㎎)and bradykinin (5 nmol) were administered into the right lateral cerebral ventricle, while arterial blood perssure and heart rate were continuously monitored throughout the experiment. Intracerebroventricular captopril did not affect the blood pressure within 10 minutes in both normotensive and 2KIC hypertensive rats, while it significantly augmented the central pressor response to bradykinin in the hypertensive rats. These observations suggest that an elevation in endogenous kinin levels is without effect on arterial pressure in normotensive and 2KIC hypertensive rats. However, the kallikreinkinin system in the central nervous system plays a role in the regulation of blood pressure, possibly maintaining the hypertension, in 2KIC hypertensive rats.

Despite the theoretical problems of the water spirometer and its poor frequency response, the water spirometer is adequate for the physiological function tests even in healthy people. We must encourage the use of the spirometer as part of routine examination of nearly all adult patients. Recently, Pulmonary function studies are widely used in evaluation of various physical condition. The aim of this study was to report the pulmonary function studies of young athletes. Subjects were 221 young athletes from 11 to 17 years of age. They were elementary school boys and girls, middle school boys and girls, high school boys and girls. The following were mainly observed for the study; frequency of breath, vital capacity, tidal volume, and breath holding time. The results obtained were summarized as follow; 1. Frequency of breath; (cycle/min. M±SD) Elementary school boys show 18±5.5, elementary school girls 19±5.0, middle school boys 17±2.3, middle school girls 17±3.0, high school boys 15±6.5, high school girls 15±5.7. 2.

"정보"의 평지육묘, 가식, Pot 이식, 차광(70%) 단일(8시간) 냉수막 처리를 한 경우 9월 6일 즉 고냉지 Pot 육묘와 같은 시기에 화아분화가 시작되었으며 처리기간은 32±2일 전후가 가장 양호한 결과를 나타내었다. 3. "정보"의 화아분화 기간은 9∼9월의 기상조건, 묘의 소질, 육묘조건에 따라 차이는 있으나 대개 11±4일 정도였다. The experiment was conducted to find out the floral differentiation time of Strawberry on growing treatments during seedling. The results are as follows ; 1. The begining of floral differentiation of "JUNG BO" Showed on September 22 in 20m sea level, without transplanting September 18 in Flat transplauting, September 15 in pot seedling, September 10 in 400m sea level transplanting, September 6 in 800m level seedling. 2. The floral differentiation time of "JUNG BO" Seedling treated in 20m sea level, transplanting to the field, pot transplanting, shading 70% for 8 hrs a day, and water spray curtain started the same day and the length of treatment for 32±2 days showed the best result. 3. The floral differentiation time of "JUNG BO" Seedling varied deend on the climate condition, seedlings strength or weakeness and seedling method, but it took about 11±4 days.

To examine the effect of cigarette smoking on pulmonary function, we undertook a analysis of 44 smokers and 41 nona dickers whose ages were from 20 to 34 years and who were living' in kwang-ju city. FVC(forced vital capacity), FEV₁ (forced expiratory volume for 1 second), FEF 200~1200, FEF 25~75%, and FEV_(1)/FVC% were calculated by determining the distance from the point of maximum inspiration to the point of maximum expiration. The results obtained were summarized as follows : 1) FVC and FEF 200~1200 showed no significant difference between smoking group and nonsmoking group. 2) In age group 30 to 34 years, FEV₁, FEF 25~75% and FEV₁/FVC% in smoking group were significantly diminished compared with nonsmoking group. 3) It seemed that diminution of forced expiratory volume for 1 second in smoking group is ascribed to diminution of FEF 25~75% of the first expiratory rate. In conclusion, the results of the present study suggested that it may be lead to small airway obstruction by long term cigarette smoking.

The purpose of this study is to develop and improve the diagnosis system for farm management. The characteristics of farm diagnosis system is the quality assessment by using checklist in Korea, but that is the quantity assessment by analyzing the farm book-keeping in Japan. The former applies easily to the oneself diagnosis of the farming but has the problem for the precise assessment, the latter has the standard diagnosis indexes with the agricultural income & expenditure, etc. So farmer can compare his own farm records with those standard indexes. But it is difficult to apply for Korean farm diagnosis, because most of Korean farmers don't keep the record on farming activity. Reviewing the problem of the 'Standard Diagnosis Chart' on rice farming, this study find out the improving measurement to the ratio of land readjustment, farm machinery operation and seed choice, etc.

호주의 쌀 산업 동향과 생산비 분석

본고는 호주의 쌀 생산동향과 변화추이, 재배기술 및 생산비 구조를 분석하여, 우리나라 쌀 산업의 경쟁력 제고를 위한 시사점을 모색코자 하였다. 이를 위해 호주의 주요 쌀 생산지를 방문하여 생산농가와 연구기관 등 관련자 접촉을 통해 현지자료를 수집분석하였다. 호주의 쌀 품종 및 재배기술 개발, 경지정리 및 수자원 관리기법, 생산자조합의 체계적인 활동과 저장가공 시설의 적재적소배치 등을 통한 생산비 절감노력 등을 벤치마킹해야 할 것이다. 경영규모의 영세성은 우리 쌀 농업이 지니고 있는 가장 큰 한계점이고, 그 결과 높은 생산비가 우리 농산물의 대외적인 경쟁력을 약화시키고 있다. 쌀을 수출하는 호주 등 주요 국가의 생산비는 우리나라의 10∼45% 수준에 불과한 실정이다. 이러한 상황하에서 자연증가에 의한 호당 경영면적의 확대는 현실적으로 매우 어려운 것으로 나타나고 있다. 우리나라 쌀 산업 발전을 위해서는 무엇보다도 생산비 절감이 매우 절실하고 그 방향은 구조개혁에서 찾아야 할 것이다. 특히, 생산기반의 구조조정 차원에서 경지정리, 교환분합, 임대차 확대, 농지집단화 노력의 배가가 시급하다고 할 수 있다. 이러한 규모화 사업이 품질향상과 더불어 우선적인 정책방향으로 추진되어야 한다. 동시에 선진국에서 막대한 예산을 투입해서 시행하고 있는 직불제도는 우리나라에서도 필요한 것이 사실이다. 다만 구조조정에 역행하거나 모순되는 직불제의 시행보다는 구조조정을 최대한 촉진시킬 수 있는 직불제가 더 현실화된 금액으로 시행되는 것이 바람직하다. 쌀 농민들의 수직적 통합이 보다 적극적으로 진행되어 농업인들의 자생적 경쟁력이 강화되어야 하며, 불합리하게 많이 설치된 RPC를 비롯한 방만한 유통조직도 재정비되어야 할 시점에 있다. This study aims to analyze the trend of Australian rice economy and production cost. Rice cultivating region is Riverina plain area in New South Wales, Australia. In recent years(1998-2000), about 1,291 thousand tonnes(paddy rice base) of rece produced on the 135,000 ha in the country. About 85% of Australian rice production exports to more than 40 countries. That makes Australia is the main exporter of Japonicatype rice in the international market. The current situation and trend of Australian rice industry and structure of production cost are described in this paper.
