This study was carried out in order to understand the plan, design, constructing and actual condition of management of modernized horticultural facilities in Kyungpook Province which had been constructed from 1992 to 1995 funded by Government support. The aim of this study is to provide reference data for success of the forth project. It was performed by making up a question about driving of project and management condition of equipment after constructing. The results obtained from this study are as follows: 1. 73.5% of facilities horticulture farmhouse recognized that the prospect of greenhouse is bright, but 92.5% of the farmhouse also recognised that they need technical consultation on protected horticulture farming. Therefore, technical educations would must be enhanced about foundation of greenhouse and cultivation technique. 2. The holding times of explanatory meetings, cause of understanding to farmhouse, were one or two times in greenhouse construction, and 62.5% of the farmhouse expressed the insufficiency at the explanation and educational data. For this reason, it was judged that the construction contract had been delayed more than 5 months in 49.3% of the farmhouse after the decision of project budget. 3. In constructing after a contract, the rates of construction delay is 53.4% and defect occurrence is 41.1%. The biggest reasons of construction delay was insufficiency of worker and materials supply. Each percentage is 29.1%. And the reason of defect occurrence is badness of machinery equipment(62.9% ). 4. In management of greenhouse, a pipe-constructed plastic film greenhouse changes plastic film every one and three years because of sticking dust on plastic film. It was needed to about in cleaning technique of coverings. Because that used 3-5 years only half of the expected life span. 5. The order of broken rating in the subsidiary equipment is like this lollop ventilator (42.8%), a general control system(33.3%) especially, in the case of a general control system, the rate of all family can control is 52.7%. so, it is time to develop easy control equipment which every one could use as soon as possible. 6. When choose heat generator as decide capacity, the most priority is the mount of heat generator the percent is 45.5% heat generator and as decide model, the private purchase's percent is 77.3%. It is higher than a public bidding heat generator the percent is 22.7% heat generator when it compare with a public bidding. In the case of $CO_2$ generator, using rate is only 19.0%. The using rate is very low, so it needs education how to use depends on the way of the subsidiary equipment. 7. In the case of seedlings, it is asked to use factory-processed seedling effectively. because it's difficult to get security of labors(58.8%), hoped crops (55.9%) access same crops(29.4%) much more and changing of crops depends on market situation. that is the main reason the lack of knowhow.

In the middle of economic and mental riches in the 21st century, the importance of well being and the pursuit of happiness are emerging as the new trend. Thus the lifestyle that values comfortable and practical naturalness and intrinsic merits has come to influence the human life rather than the old showing-off and formal desire. In addition to this, the spread of the five day week has given more leisure time, which has led to the increasing interest in health and leisure. The interest in sports has skyrocketed since the successful holding of the 2002 Korea and Japan World Cup event. All these changes to the lifestyle have contributed to the fusion of luxury wear and sports wear. As the result of the consumers in the 21st century having more classified and upgraded way of living thanks to the settlement of the above-mentioned lifestyle and the enlargement of the leisure sports culture, there has appeared the wellness kin, who value the importance of life and the nature and believe in the idea that they can reconstruct the environment in the way they can enjoy their lifestyle and pursue happiness. They favor healthy fashion items and think much of exercise, nutrition, and rest. They pursue the natural and comfortable style, whose ideas came from simple exercises such as health training and yoga and the easy and comfortable look observed at resorts. Their fashion style can be divided into three of fitness fashion, yoga fashion and resort fashion. First, the boxer fashion is characterized by the relaxing design and practicality. The major items of the fashion include running shirt-styled upper clothes, training pants, hooded shirts and sneakers. Simple and comfortable look should be induced from the combination of the items. Second, the yoga fashion was motivated by the comfortable yoga wear. It advocates stress-free spirit and comfortable and stable naturalism. Along with the advantages of the good feeling to wear and the functionality to help exercise better, the yoga fashion gives the wearer enough room to move around in, using the unique lines. Third, the resort wear refers to the kinds of clothes you tend to wear at the beach and the park. There are various kinds of the resort look; bathing suits, the beach wear you can wear with the bathing suit, the resort evening wear, the full-side look that you try on top of the bathing suit and is made of the same material of the bathing suit, and the marine look, the symbol of the summer. In short, the study attempted to investigate many trends occurring as the result of human recent increasing interest and concern in the quality of life, and the impacts of them on the fashion world. This kind of research that examines the background of the times and society will help to grasp with the fashion trends of the present and the future. And more studies should be conducted on the development of new and original design in clothes fashion, which reflects the characteristics identified in this kind of research.

Development process of agricultural technology has been studied with a case study of Korean agriculture. Technological is considered as a transformer of inputs into outputs and hence technological appropriateness, an important aspect of agricultural development strategies, is considered as a dynamic concepts. Considering the concept of agricultural system as a delivery system for providing essential materials and services to producers and consumers, it has been divided into two major groups of dimensions vis. external challenge dimensions and internal response dimensions. Market, investment and agro-ecosystem constitute the external challenge dimensions : whereas trade , technology as well as production and resources allocation constitute internal response dimensions. The system manager is responsible for maintaining equilibrium in the mentioned six sub-systems. Two kinds of alternatives paths of technological development viz. land saving technology and labour saving technolog have been studied. Technology is considered as a combination of four basic components viz. facilities, abilities, facts and frameworks. Adoption of innovation in agriculture depends on profitability, awareness, risk aversion, financial capacity, institutional infrastructure, availability of physical inputs and adaptability to the local conditions. For a cast study of Korea, changes in the agricultural system through external challenge dimensions are investigated. The impacts of industrialization on agro-ecosystem reported are shift of labour from the agricultural sector to non-agricultural sectors and continuously increasing demand of farm the agricultural sector to non-agricultural sectors accompanied by increase in land prices. The impacts on the commodity market discussed are shift in demand from rice, barley and other cereals to meat , dairy products and vegetables : and increasing in supply capacity of agricultural inputs. The process of agricultural development from 1962 to 19 1 9 (i.e. from start of the first to the end of the sixth five year plan) are also discussed in details with several policy measures taken. The trend of agricultural income and productivity are also analyzed. The main cause of increase in the agricultural income is considered as increase in labour productivity. The study revealed that during the span of 1965-88, holding size has not changed significantly, but both the land and labour productivity increased and so did the agricultural income. R&D activities in Korea have changed over time in three stages vix. import of improved technology, localization by adaptive research and technological mastery. For the new technology to be made affordable to farmers, policy measures like fertilizer and food grain exchange system, dual price system in rice and barely and loan for machinery were strengthened.

대체로 활성슬럿지 공법에서 가장 큰 문제점은 처리후의 미생물의 분리, 슬럿지 반송, 잉여슬럿지의 소화이다. 반면에 생물학적 고정막을 이용한 RBC, 실수여과상, 고정층활성 슬럿지 공법들은 이와같은 문제가 해소된다. 최근 침전시설 및 농축조를 설치할 필요가 없느 반고정망 활성슬럿지 공법이 개발되었다. 이 공법은 최종 처분할 슬럿지량도 감소되며, 유출수의 수질도 양호하고 최대축척용량으로 유출수의 수질은 추정할 수 있으나, 반응조가 동적인 수리학적 양상의 결여 되어있었다. 따라서 본 연구에서는 반응조가 좀더 동적 수리학적 양상이 되도록 설계하여 운전하였으며 그 운전결과는 다음과 같다. REMSMAS 공법은 침전시설 및 농축시설없이도 양호한 유출수를 얻을 수 있었으며 슬럿지 부착능력도 RESMAS 공법이나 FAST 공법 보다 크게 나타났으며 최대축척용량에 도달되는 한계운전기일은 대략 유기물부하량에 비례하였다.

The current study was conducted to investigate the effects of dietary chitosan-alginate-Fe(II) complex (CAFC) supplementation on carcass and meat qualities of pig m. longissimus during chiller ageing. One hundred and twenty-two LYD (Landrace${\times}$Yorkshire${\times}$Duroc) pigs were sampled from an industrial population. Seventy-four pigs (32 gilts and 42 barrows) were administered 3 ml of dietary supplementation of CAFC per day from 25 to 70 days of age, while the remaining 48 pigs (20 gilts and 28 barrows) were fed the same commercial feeding regime without the supplementation. For assessing the dietary effects on pH, objective meat color, cooking loss, water-holding capacity (WHC), thiobarbituric acid reactive substances (TBARS), volatile basic nitrogen (VBN) and fatty acid composition during ageing, 20 barrows (10 of each treatment) were randomly sampled, and aged for 3, 7, 12, 16, 20 and 25 days in a $1^{\circ}C$ chiller. The results showed that CAFC-fed pigs required approximately 10 fewer feeding days than the control group. Furthermore, the treatment resulted in greatly higher carcass grade whereby the grade A was increased by approximately 35% and 7% for gilts and barrows, respectively. The treatment had no significant effect (p>0.05) on pH, meat color and WHC during ageing. On the other hand, the CAFC-fed pigs showed significantly (p<0.05) lower TBARS values from 20 days of storage. In addition, the sum of unsaturated fatty acids for the treated group was significantly (p<0.05) higher than that for the control group after the storage time. This implied that CAFC supplementation could reduce the formation of free radicals in fatty acids (i.e., lipid oxidation). The treatment also significantly (p<0.05) retarded VBN formation during ageing, indicating a significant reduction in protein degradation. However, as there was no difference in pH between the two groups, the result raised a possibility that antibacterial activity of the CAFC alone could cause reduction in the formation of TBARS and VBN. In this regard, although the treatment effectively slowed down the formation of TBARS and TBA during chiller ageing, it was not resolved whether that was associated with the direct effect of the antioxidant function of chitosan and/or alginate, or a consequence of their antibacterial functions.

최근 우리나라 기술발전과 글로벌화 경향에 맞추어, 의료기기산업도 국제적인 의료기기관리제도에 적합하도록 체질을 개선해 가고 있으며, 국제적인 규제수준에 도달할 수 있도록 완화의 가닥을 잡고 있다. 또한 최근의 입법 경향을 보면 의료기기 산업의 각종 규제는 최소한의 범위에 머물고 새로운 기술의 결합 내지 융합에 개방적인 자세를 취하고 있다. 결합 의료기기에 활용된 의료기술은 대부분이 인체나 환경에 위해성이 없는 의료기술일 가능성이 크므로, 이렇게 위해성이 제로에 가까운 의료기기를 1등급으로 분류하여 위해성이 거의 없는 의료기기와 같이 취급함으로써 발생하는 불필요한 행정력과 시간의 낭비를 최소화할 수 있다. 이를 통하여 의료기기 취급자 특히 판매업자에 포함되는 사업자의 영역이 넓혀지므로, 사업자들의 사업의지를 고양할 수 있으며, 국민의 의료기기에 대한 선택권과 접근권이 제고될 수 있다. 본 논문에서는 결합 의료기기의 중고 수리 및 유통질서를 확립하고 공정한 거래를 촉진하기 위한 제반의 법률을 조사하고 규제를 개선하는 방향을 제시한다.

본 논문에서는 스마트 전력량계 집중장치와 검침서버간에 사용할 수 있는 개방형 프로토콜을 제안하고 성능을 분석하였다. 기존의 집중장치는 DLMS/COSEM 표준프로토콜 기반에서 스마트 전력량계에 대한 연결설정 및 데이터 수집절차를 수행한다. 하지만 수집된 자료를 전달할 때 필요한 집중장치와 검침서버간에는 표준화된 프로토콜이 없어 제품마다 다양한 방식으로 구현되고 있다. 본 논문에서는 집중장치와 검침서버간의 프로토콜로 기존의 DLMS/COSEM 표준프로토콜을 확장한 개방형 프로토콜인 Smart Meter Concentrator Control Protocol(SMCCP)를 제안하였다. 이것은 집중장치로 하여금 검침서버를 대신하여 검침자료를 수집할 수 있는 프록시모드 뿐만 아니라 검침서버와 전력량계간의 직접 통신이 가능한 릴레이모드도 설정하고 자료를 수집할 수 있는 기능을 제공하도록 설계된 것이다. 본 논문에서는 이의 동작을 실증할 수 있는 에뮬레이터 및 프로토콜 분석도구를 구현하였다. 또한 각 모드에 대한 동작과 성능을 평가하기 위하여 OMNET++기반의 시뮬레이터를 구현하여 모드별 평균세션유지시간 및 통신링크 점유율을 측정하고 비교하였다.
