In recent years, Unmanned Aerial Vehicles (UAV) have been developed for both military and civilian activities in regions where the presence of onboard human pilots is risky or not necessary. However, UAV require a high demand of power to achieve its missions such as taking images/videos in a certain area or surveillance activities. Therefore, this situation triggers the need of techniques to reduce power consumption for UAV to complete its mission safely. One of the methods is to use a waypoint optimization procedure which deals with a pre-specified set of waypoints to find a minimum route to fly through those waypoints in order to reduce power consumption. In this paper, due to the UAV's multidisciplinary which makes it impossible to be represented as an analytical model, we design a simulation model of UAV using MATLAB Simulink and AeroSim Blockset, an analysis package in aerospace industry. The simulation model is then coupled with optimization algorithms along with a set of waypoints (flight path) in order to measure at which percentage power consumption can be minimized for UAV.

We estimate consumer price indexes of eight major cities from 1907 to 1939, and then integrate them into a national level one. The data mainly came from the Statistical Yearbooks of the Government-General of Colonial Korea, and if necessary, we supplement them using wages and unit prices of public utility charges which are used as the price of housing and various services. We apply Laspeyres index method, and the composition ratios of consumption expenditure estimated by the commodity flow method are used as weights. The price indexes of 12 item groups as well as aggregate one are also calculated. In case of Seoul, it is possible to calculate the consumer price index from 1907 to 2009, showing a century-long pattern. This consumer price index is critical for measuring the real income and expenditure before the liberation.

This study was to investigate the consumption pattern and nutrition knowledge about vegetables of 184 housewives attending the school of adult and continuing education attached to DukSung Women's University. The results were summarized as follows; the average vegetable expenses were $10,000{\sim}20,000$ won per week. The frequency of purchasing vegetables was $2{\sim}3$ times a week. Respondents usually bought the vegetables at local markets and supermarkets. As for buying vegetables, all of respondents kept in mind all the time the organic vegetables were better. The price was the most important factor of their purchase in the low income households. In the family, the vegetable dishes were favored by housewives most and by sons least. Among the vegetable cooking methods, Kimchi was the most frequently used and salad was the least. Forty four percent of the respondents experienced purchasing ready made vegetable dishes in the market. The reason they bought ready made ones was the special taste of the dishes. The rest of respondents never bought cooked vegetable dishes because they thought the dishes unsanitary. Twenty seven percent of the respondents experienced purchasing. The reason for not purchasing Kimchi was the housewives' traditional prejudice of buying Kimchi in the market. Respondents have a considerable knowledge that 42 kinds of vegetables could be good for certain disease and 10 kinds of vegetables might be harmful for certain disease.

Encouraged by the investment in the rice paddy, the introduction of new varieties (Tong-Il), and the price support program, there has been great success in increasing rice production. Meanwhile, the demand for rice has decreased rapidly as per capita income continues to rise. Rice self-sufficiency has been attained, and a new over-supply problem is emerging. Moreover, the Uruguay Round Agricultural Negotiation would prohibit government price support for agricultural products. In October the Korean government decides the government purchase amount and support price, which works as the price guideline. All interested parties exert political efforts to influence the decision. The continued increase of the government purchase price of rice due to political pressure pushed the government purchase price above the market wholesale price in 1988. Also, the farmers preferred to sell to the government than to the wholesaler. This has discouraged the market mechanism, and the government is to take over the three functions of the market mechanism: stockpiling, seasonal price fluctuation adjustment, and circulation. Another big increase may cause the government purchase price to rise above the consumer price, which might lead to arbitrage opportunities for the farmers and suffocate the market mechanism. However, the current political situations limits the options for the Korean government. This paper argues that a supply control policy will reduce the social cost resulting from the high level of producer price support, and it proposes several second best policies: First, the production of new varieties should be reduced rapidly. Second, the old rice in the government warehouse should be auctioned or disposed of in order to reduce the government handling and management costs. Third, the acreage diversion program should be launched in order to control rice paddy acreage. Fourth, a social welfare program in rural areas should be introduced, since the share of population over 60 is increasing rapidly. Fifth, instead of the price support which is forbidden by the Uruguay Round, Korea should restructure the agricultural industry by developing new crops, by enhancing productivity and by improving the agricultural infrastructure.

21세기에는 인구의 폭발적 증가와 함께 가속화된 산업화로 말미암아 경지 면적은 줄고 농업 환경은 더욱 피폐해질 것으로 예상된다. 지금도 이미 화석 에너지원의 고갈로 대체 에너지 개발이 시급히 요구되고 있으며, 지구의 자연 환경 보존 목소리도 그 어느 때 보다 높다. 한마디로 식량, 에너지, 환경 문제가 새 세기에 우리가 시급히 해결해야할 과제로 주어져 있다. 이에 과학계에서는 식량 및 대체 에너지원의 공급을 증대시키고 환경을 보존할 수 있는 보편적인 수단으로 환경 친화적 유전자 변형 (GM)작물의 활용이 제시되고있다. 따라서 선진국들은 이의 기반이 되는 식물유전체 연구에 대규모 투자를 아끼지 않고 있으며, 이를 이 용한 식물 생명공학산업을 국가 전략 산업으로 집중 육성하고 있다. GM작물 제조 기술은 유용 유전자의 발굴 및 재조합, 식물세포로의 이식 및 재분화를 통한 완전한 식물체 재생, 이를 품종으로 실용화하는 단계로 구성되어 있다. GM작물은 1983년 항생제 저항성 담배가 개발된 것을 시점으로 하여, 1994년에는 연화지 연 토마토 Flaver Saver이후 지금까지 개발 실용화된 작물은 제초제 저항성 콩, 카놀라, 목화, 그리고 해충 저항성 옥수수 등이 있으며,2001년까지 세계적으로 상품화 승인을 얻은 경우는 15 작물 68품종에 이른다. 2001년 경우 GM작물 종자시장은 약 30억 달러에 달하고 있으며, 미국, 아르헨티나, 캐나다 등 세계적으로 52.6백만 ha에 이르는 면적에서 재배되었다. 그러나 GM농산물의 식품 및 환경 안전성에 대한 의구심이 일기 시작하였고, 따라서 이의 생산 및 소비에 대한 전반적 인 문제가 뜨거운 쟁점으로 부각되기도 하였다. 이 에 각국 정부는 객관적 인 안전성을 확보하기 위한 제도적인 장치를 마련하고 있으며, 아울러 과학기술자들은 더욱 안전한 형질전환 기술 개발을 도모하고 있다. 다음 세대의 GM작물은 단순한 제초제 및 병해충 저항성을 넘어서서 특정 영양 또는 건강기능성을 향상시켜 부가가치를 증가시킨 신품종 맞춤작물이 지속적으로 개발 상업화될 것이다. 따라서 고유성을 가진 유용 유전자의 대량 확보 여부가 산업적 경쟁력을 결정하게 될 것이다. 지금까지 개별 유전자 중심으로 이루어지던 유용 유전자 발굴 작업은 유전체학의 출현으로 규모가 대량화되고 그 효율이 증진되었다. 따라서 진 각국은 유용 유전자 발굴에 국가적 차원의 역량을 집중하고 있다. 그러나 우리나라는 정부와 민간의 소규모 지원으로 근근히 기술 습득 차원에 머물러 왔으며, 산업적 경쟁력의 무기가 될 고유한 유용 유전자와 형질전환 기술이 거의 없는 어려운 상황에 놓여 있다. 최근 정부가 시작한 생명공학 분야 대규모 연구지원 사업 기대를 모아 보며 이 분야 과학기술자들의 노력을 촉구한다.
