Importation of fruits has been completely liberalized since July 1, 1997, in Korea. This makes the future of Korean fruit industry unstable. In order to cope with this unfavorable situation, long-term fruit supply and demand forecast should be made and fruit policy should be put into implementation accordingly. Major fruits covered in this study are apples, pears, peaches, grapes, persimmons, oranges and miscellaneous fruits. Their overall demand is expected to increase by 22% compared with the average of 1995-1996 in 2020. Considering the past trend, yields of those fruits were forecast first and acreage forecast was made later on. The major concern of this study was a future forecast of necessary acreage for each of the major fruits mentioned above. With self-sufficiency of them in mind, their necessary acres were forecast and those of apples, peaches, grapes, and persimmons would increase whereas those of oranges and pears would decrease according to the assumption which reflects the past trend.

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.

The cardiopulmonary bypass or cerebral circulation arrest is often used in the treatment of complex aneurysm or of arteriovenous malformation to decrease the risk of intraoperative aneurysm rupture. Although experimental studies have suggested that some drugs may protect the brain from ischemic injury, there are limitations in maintaining cerebral perfusion arrest without incurring neurologic deficits due to the initiation of detrimental processes including excitotoxic neuronal injury, activation of phospholipases, influx of calcium, and generation of damaging free radicals. The purpose of this study is to determine wheter mannitol or thiopental has any favorable effects on the recovery of neurologic deficits and on the regional cerebral blood flow(rCBF), somatosensory evoked potential(SEP) and electroencephalogram(EEG) in cats which underwent 15 minutes-complete global ishcemia-reperfusion. The complete global ischemia was produced in 38 cats by temporary intrathoracic occlusion of the innominate artery and the subclavian artery following ligation of bilateral mammary arteries and simultaneous induction of hypotension. The cats were allocated randomly to one of 4 treatment groups : (1) control group, 8 cats received equal volume of saline solution : (2) thiopental group, 10 cats received 45㎎/㎏ thiopental intravenously, (3) mannitol group, 10 cats received 2g/㎏ mannitol intravenously, (4) combined mannitol and thiopental group, 10 cats received equal dose of mannitol and thiopental intravenously. The drugs were administrated in a equally divided dosage before and after the ischemic episode. The results were as follos : 1) Eight animals which received saline showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours after the ischemia. 2) Ten thiopental-treated animals also showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours the ischemia. 3) Both mannitol-and combined treated groups showed early recovery of EEG, good recovery of SEP and EEG without the severe postischemic hypoperfusion, and 7 of 10 mannitol-treated animals and 8 of 10 combined treated animals were significantly recovered in all parameters. There were not significant differences in all parameters between the mannitol-and combined treated groups. 4) Thirty-four of 38 animals involved in this 15 minutes-ischemia resulted in the severe neurologic deficits inspite of treatment with mannitol, thiopental or both of them. These results suggest that, in cats, mannitol treatment is effective but not thiopental in preventing severe neurologic injury following complete global ischemia and the duration of complete ischemia should be far less than 15 minutes.

Rice industry has been the core of agriculture in Korea. In order to strengthen its viability under the open market system, Korea needs to improve its competitiveness in terms of production cost, price, and quality of rice. This study aims to analyze the current situation and prospects of rice economy in China. China is the largest country of rice production and consumption in the world. In recent year, 2000, about 188 million M/T(32% of world rice production) of rice produced on the 30 million ha in the country. Average yield is 6.27㎏/㏊ based on paddy rice. China is the main exporter of Japonica-type(short & medium grain) rice in international market. Japonica-type rice accounts for about 32% of total rice in China, and the component is increasing trend now. The average production cost of China rice was about US$130/MT(milled basis) in 2000.

Agricultural Parity Ratio Its effects upon-Grain supplyAccording to economic theory, favorable or unfavorable agricultural prices usually can induce a marked influedce upon the rate at which new technology is adopted, and , in return, upon the rate of change in agricultural supply. In order to apply this theoretical hypothesis to grain production in Korea, various agricultural parity ratios were made up and used as explanatory variables in both production and yield response functions of grain croup. Other variables such as weather and new variety fo high-yielding rice were also included in this analysis. Both price elasticities of supply and yield were calculated from estimated econometric models. Three kinds of model were employed on oredr to estimate and analyze the different responses to different parity conditions over time, The reuslts show that favorable parity conditions have impacts upon the agricultural supply positively. Elasticities of supply range from 0.15 to 0.35 according to the three models estimated in this study. They show that if a favorable parity ratio is maintained over a longer period, the more elastic is the supply response. The same results were obtained in yield analysis. Therefore, it is argued that favorable agricultural parity ration should be created and maintained in order to improve agricultural productivity and thereby increase total grain production.

There is mo formal evaluation system to identify a array of legal decision elements of a construction site. This paper introduces the constitution of hierarchy for applicable legal contents on a construction site to evaluate the architectural use and the size. The introduction to new evaluation system of architectural legal contents is an evolutionary process where acceptability is based on the analysis of applicable legal items for a construction site. This ability to make good feasibility is a very important aspect of the construction process. The method used relied on subjective judgements based on the analysis of architectural legal items related with construction permit. In making systems we should decide the applicable legal items which are most appropriate to constitute the methodology. The case study requires us to consider the effective legal items available which influence the use and the size of the architectural buildings.
