"Treatise on cold damage and miscellaneous disease" is a ancient formula records on keeping in good health, provided "Internal classic" is a ancient codes on keep in good health. It can be inferred that Zhang Zhongjing was a first inheritor of academic ideology from "formula followed by establishment of the therapeutic principles". Before writing and compiling the "Treatise on cold damage and miscellaneous disease", Zhang zhongjing got the essence of "Internal classic" after composing and utilizing "Plain Questions", "Miraculous pivot and classic of difficult issues", so all the theory foundations of "Treatise on cold damage and miscellaneous disease" came from "Internal classic". The keynote of internal classic lies in obeying the Yin and Yang in natural world and preserving and maintaining the yang-qi of human body to attain the longest life-span. Zhang assimilated the essence of "Internal classic" and then generated a new ideological system - "Treatise on cold damage and miscellaneous disease" when studying it. This article is to expound ideology inheritance of keeping in good health by protecting Yang in "Internal classic" from analyzing the usage of Guizhi in "treatise on cold damage diseases".

In order to provide fundamental data for the achievement of safe environmental condition, investigation of the actual state of the nutriculture practices in Korea was carried out. The result obtained are summarized as follows. 1. Cultivation area of nutriculture was 6 ha and culture types included deep flow technique(43%), nutrient film technique(45%), gravel culture(6%), chaff charcoal culture(3%) and rockwool culture(3%). 2. Greenhouses were mostly made of pentite pipe frames and covered by polyethylene film, and culture beds were handy combination of cement blocks, concrete and styrofoam, which were not standard products. 3. Development of nutriculture system appropriate to our actual circumstances and improvement of establishments are required. 4. Since there was not farmhouse that performs the environmental measurement and environmental conditions of cultivation were very limited. sensor applied environmental control technology of nutriculture should be developed.

Importance of alternative energy has been increasing due to environmental issues and lack of fossil fuels. In addition, heating cost that occupies from 30 to $40\%$ of the total production cost in the protected cultivation sector in Korea needs to be reduced for profitability and global competition. But, study on geothermal energy to solve these problems has not been activated for Korean protected cultivation. This study was conducted to develop an optimized geothermal exchange system through fundamental test of heat transfer characteristics in soil such as thermal diffusivity, changes in soil temperature during heating and cooling operations, and restorations of soil temperature after the heater was fumed off, These issues were investigated using computer simulation for different depths. The simulated characteristics were evaluated through controlled tests. Simulated characteristics of heat transfer in the soil at different depths showed a reasonable agreement with the results of the controlled tests. All of computer simulation and controlled tests, soil temperatures changed at 10cm and 20cm distance from pipe. but don't change at more than 30cm distance. It means that distances of heat transfer of the soil ranged from 20 to 30cm a day. Based on these results, the optimum spacing between adjacent heat exchange pipes and the pitch were selected as 50 and 40cm, respectively.

The major problems of food crop cultivation in Korea are low yield of most crops except rice. inefficient cultivation techniques for aged farmers. and low international competibility. Therefore, development of cultivation techniques of food crops should aim the yield. quality improvement, labor reduction and production cost. The primary issue for increasing the yield of soybean, barely and wheat is to reduce the yield gap between the farmer's yield and recommended ones of experiment station. More advanced cultivation techniques needs to be developed. and/or the conventional breeding methods to be reconsidered. The newly developed labor-saving mechanized technique needs to reduce labor hours , and the cost of agricultural implements and machineries. In other words the labor-saving mechanized technique should be developed based on the improvement of total farming system as well as systemic fundamental innovation of cultural methods. The efficiency of solar energy use in food production of Korea in 1997 is as low as $0.52{\%}$ so there is much room to increase yield. It is recommendable that the concept of food Production should be changed to energy Producing efficiency Per unit area basis from volume and weight of food materials. Moreover, introduction of resonable cropping system is needed to increase yield of main crops, farmer's income, solar energy use efficiency, and decrease of land service expenditure. Current cropping system emphasized on economic crops. especially in vegetables , is not desirable for resonable use of arable land. stability of agricultural management and staple food crop self-sufficiency ratio. It is desirable to increase food crops . that are energy of carbohydrate and protein rich and land dependent crops. in cropping system. And the agronomist should develop the cultural methods to replace food crops for food self-sufficiency and stable farming management instead of economic crops in current cropping system. Low-input and environmentally-sound crop cultivation techniques, especially nitrogen-reducing culture technique which is directly related to food crop quality, also needs to be developed urgently. The extended cultivation of corn in upland and barely and wheat in lowland as a feed stuffs is recommended to prevent further decrease of food self-sufficiency ratio, which is mainly caused by the high reliance on imported feed grain. It is also considered that the calculation and presentation methods of standard agricultural income needs to be improved. The current calculation method uses unit land area of 10a regardless of crop kinds , characteristics of agricultural management and cultivation scale. So, it is apt to lead misunderstanding of farm income value. Therefore. it should show an income of average farmers for certain number of years. Research and developing system for food producing is not desirable because they are conducted currently individual crop and mono-culture basis. But actual agricultural income is usually earned by cropping system including upland and lowland. For example. the barley and wheat is usually cultivated in double cropping system. The cooperation among research institutes such as university agribusiness. government and farmers is indispensible. The public information and education on importance and consumption habit of food crops is necessary in Korean society to increase food self-sufficiency through nationwide cooperation.

Soil moisture control system including soil sensing and automatic water supply chain was constructed on open farmland and pot conditions. Soil moisture was controlled by the system showing over the soil moisture contents except 40% treatment. EC was gradually decreased by increasing cultivation days. On applying this system to control soil moisture, the growth and development characters of the bellflower were improved compared with control, cultivation without the automatic irrigation. Of the growth and development characters, plant height with water treatments was higher than that of control in 1st-year plants. Moreover, numbers of branch were increased by the increased soil moisture on farmland and pot condition. Capsule numbers for seed were best at 20%, 30% soil moisture treatment in 1st-year plants, and 20% to 50% treatment in 2nd-year plants. The construction of automatic soil moisture control system provide fundamental data for plant growth and development on open farmland soil condition.

오늘날 수학교육에 있어서 가장 중요한 문제 중 하나는 학교수학의 인간교육적 기반을 회복하는 것이며, 이를 위해서는 '수학을 가르치는 이유는 무엇인가'라는 보다 근원적인 문제에 대한 논의가 새롭게 요구된다. 본 논문은 생활의 문제 해결이나 과학 기술을 위한 유용한 도구적 지식교육을 지향하는 오늘날 수학교육에 대한 문제 의식에서 출발한다. 먼저 '마음의 중층구조 이론에 비추어 이론적 지식 중심의 수학교육의 의미를 분석적으로 논의하고, 과거 교육사상사에서 수학교육이 어떤 인간교육적 이념을 추구해 왔는지를 Platen과 Froebel의 교육론을 통해서 살펴보았다. 그리고 20세기 초수학교육 개혁운동을 선도하여 현대의 수학교육 천학 및 수학 교육과정의 기본바탕을 제시한 F. Klein의 수학교육론을 고찰하였다. 특히 Klein의 수학교육 사상의 이면을 보다 명확히 드러내기 위하여, '마음의 중층구조'에 비추어 그의 수학교육론을 심성함양이라는 측면에서 재음미하였다. 또한 Klein의 수학교육 이념에 대한 보다 발전적인 논의를 위하여 Klein 이후 수학교육 발전과정에서 드러난 몇 가지 연구결과를 종합하여 심성함양으로서 '함수적 사고' 교육에 대한 발전적 고찰을 시도하였다. 이상과 같은 고찰을 통해 실용적 가치 추구로만 여겨졌던 오늘날의 수학 교육과정의 이면에 심성함양으로서의 인간교육적 가치가 핵심을 이루고 있으며, 수학교육은 그러한 가치 추구를 중시함으로써 심성함양에 기여해야 함을 논하였다.

본고는 크게 3부분으로 구성된다. 첫째 학문의 본령, 둘째 학문의 방법, 셋째 학문의 비전이다. 학문의 본령은 공부의 목적, 학문의 방법은 공부 방법, 그리고 학문의 비전은 공부의 달성 결과를 염두에 둔 표현이다. 학문의 본령으로 성인지학을 거론한 것은 양명심학의 목적이 성인지학임을 분명히 밝히고자 함이다. 양명학이 성인지학을 추구했다는 평가는 극히 상식적인 것 같지만 의외로 많은 경우 이에 대한 이해가 미묘하게 갈린다. 이와 같은 현상이 발생하게 된 데에는 신유학의 발단인 송대 이학이 성학을 강하게 추구했다는 것이 상식이 된 마당에, 주자학을 비판한 양명학이 성학을 확고하게 추구했다는 것은 언뜻 보기에 타당한 주장처럼 보이지 않기 때문이다. 학문의 방법으로 거론한 치양지가 양명학의 핵심 공부론임은 굳이 재론의 여지가 없다. 그러나 치양지 공부에 대한 구체적인 이해에 있어서는 명대 양명후학들의 분화가 보여주듯이 다양한 견해가 병존한다. 본고에서는 두 가지 문제를 다루었다. 첫째는 주자가 즉물궁리설(卽物窮理說)를 제창한 이유를 밝힘으로써 주자학 공부론과 양명학 공부론에 대한 기존의 '일존일폐(一存一廢)' 식의 지리한 논의를 반성해보고자 하였다. 둘째는 치양지 공부론에 대하여 일반적으로 범하는 실수를 검토해 보았다. 이는 양지학(良知學)을 올바로 이해하는 관건이기 때문이다. 학문의 비전에서는 양명심학 안에서 천지와 한몸이 되는 경지를 추구하는 인(仁)의 철학을 살펴보았다. 통상적인 양명학 연구는 주자학의 안티테제로서 양명학의 의의 또는 한계를 논하는 것이 밑바탕에 깔려 있어서, 양명 철학 안에서 '만물일체지인(萬物一體之仁)'을 주목하는 경우는 비교적 제한적이었다. 본고에서 상정한 3대 강령들을 한편의 논문에서 다루는 작업은 필연적으로 철학 논문이 갖추고 있는 구체적이고 자세함의 미덕을 희생하지 않을 수 없다. 그러나 대신에 양명심학의 전체적인 특징을 이해하고 그 핵심을 파악하고자 하는 비양명학 전공자들에게는 충분히 일독의 가치가 있을 것이다.

This study was performed to figure out an optimum water environment and to obtain the fundamental data related with saving labor and water consumption for the chinese cabbage being grown in greenhouse . The productivity of cabbage cultivated in boty pots and floor were compared to each other in the aspects of height and weight depending on the soil saturation levels. Obtained results are as follows. ; In case of pot cultivation , the height as well as weight of cabbage in 80% soil saturation level(P80) were measured to be larger than those in the other 2 soil saturation leves (P100 and P60). The weight of floor cultivated cabbages were relatively larger than that of pot cultivated ones. In accordance with saturation ration, the general trend of water consumption rate was maximum in P80 and was decreased in the order of P80 , P100 and P60. And the average indoor temperature as well as the plant growth rate were found to be closely related with water consumption rate.

Owing to the industrialization, the urbanization and cultivation abandonment actual condition, the most abandoned farmlands increased. Those results have occurred inefficient land use and destruction of agricultural ecosystem with the secondary succession. The research for the abandoned farmlands of Korea is fundamental phase. Also, the researches to restore abandoned farmlands are something yet to develop and not established the restoration for ecological value of abandoned farmlands. The objective of research revealed the ecological functions of abandoned farmlands and it presented an application plan. The research method divided in the literature and case study. Using abandoned farmlands, Japan government tries to create the ecological parks for the conservation of a vulnerable plant species, dragonfly biotope, environmental education and research, etc. Accordingly, the goal for the abandoned farmlands coulds be set suitably to Korean situation as of Japanese styles which are characterized by man-made biotopes.
