In order to increase the fruit ripening acceleration of sweet persimmon, used chemicals treatment and obtined the examination results as follows: 1) The suitable time of Ethrel spray on sweet persimmon is considered about on September 25th. 2) The fruit fo sprayed Ethrel on September 25th was accelerated the ripening for 8 to 10 days. 3) The whole surface spray on September 25th was showed lower of fruit's weight, hardness, tannin and the sweetness higher than the fruit surface sprayed. * The whole surface spray was showed lower of fruit weight, tannin and higher of sweetness than control. * The fruit surface sprayed was showed higher of fruit weight and sweetness and lower of hardness and tannin than control. 4) The fruit weight sprayed on October 4th was high of Ethrel 50ppm, and the hardness, sweetness and tannin were tended to the same as treated on September 25th. 5) Etherel spray section had increased the softening as well as accelerate the fruit ripening. 6) Gibberellin mixed section had increased the fruit bardness and raised the storage effect, however the fruit fleshiness was showed some suspensible tendency. 7) 2,4,5-TP Section was showed the low of hardness and storage effect, however it had some ripening effect.

剪斷變形과 回轉貫性을 考慮한 圓筒쉘의 動的解析

權宅鎭,韓相乙,徐三悅 成均館大學校 科學技術硏究所 1986 論文集 Vol.37 No.2

Not only is the knowledge of natural frequencies and modes of structures important from a design viewpoint to avoid resonance condition, but it is also the foundation for forced response calculations. And the increasing use of thick shells in industry has necessitated efficient theoretical analysis particularly in dealing with the effect of transverse shear deformation. The present paper is concerned with the formulation of suitable stress-strain relations and the basic equilibrium equations of shell structures, which consider the effect of tranverse shear deformation and rotatory inertia, are deduced by application of Hamilton's principle. Also, these equations are applied to circular cylindrical shell and the results are compared with the simplified classical theories.

권승구 동국대학교 사회과학연구원 2005 사회과학연구 Vol.11 No.2

Agriculture is evaluated as an industry that has low competitive power and efficiency. However, the competitive power and efficiency are evaluations only in the side pf price aspect. Environmental aspect besides price factor is very important competitive power and efficiency as a part of multifunctionality. Especially, constructionpolicy of ecological village based on combination of agriculture, region, and environmental ecology is considered as a good alternative plan. In the sense of the meaning agriculture is a hope and future industry in the 21 century.

퍼지추론 방법을 이용한 교통경로선택의 모델링

오성권 圓光大學校 1996 論文集 Vol.31 No.2

퍼지모델링의 설계 방법을 교통경로선택의 모델동정을 위하여 제안한다. 제안된 퍼지모델은 최적화이론, 퍼지구현규칙을 사용하여 "IF... THEN..."의 효율적인 형태로 시스템구조와 파라미터 동정을 시행한다. 이 논문에서 간략추론, 선형추론, 변형된 선형추론의 3가지종류의 퍼지모델링 방법을 제시한다. 이 퍼지추론 방법은 인간의 교통행동의 정확한 추정과 정밀한 묘사를 위해 교통경로선택 모델을 개발하기 위해 이용된다. 퍼지규칙의 전반부 구조와 파라미터를 동정하기 위해 개선된 컴플렉스법을 사용하고, 최적 후반부 파라미터를 동정하기 위해 최소자승법이 사용된다. 교통경로선택 데이타가 제안된 퍼지모델 성능을 평가하기 위해 사용된다. 제안된 방법이 기존의 다른 연구들-즉 BL, PS, FL, NN, FNNs모델 등- 보다 더 높은 정확도를 가진 퍼지모델을 생성함을 보인다. A design method of fuzzy modeling is presented for the model identification of route choice of traffic problems. The proposed fuzzy modeling implements system structure and parameter identification in the efficient form of "IF..., THEN..", using the theories of optimization theory, linguistic fuzzy implication rules. Three kinds of method for fuzzy modeling presented in this paper include simplified inference (type 1), linear inference (type 2), and proposed modified- linear inference (type 3). The fuzzy inference method are utilized to develop the route choice model in terms of accurate estimation and precise description of human travel behavior. In order to identify premise structure and parameter of fuzzy implication rules, improved complex method is used and the least square method is utilized for the identification of optimum consequence parameters. Data for route choice of traffic problems are used to evaluate the performance of the proposed fuzzy modeling. The results show that the proposed method can produce the fuzzy model with higher accuracy than previous other studies-BL(binary logic) model, PS(production system) model, FL(fuzzy logic) model, NN(neural network) model, and FNNs (fuzzy-neural networks) model-.

정의권,김성재 중앙대학교 스포츠과학연구소 2001 體育硏究 Vol.- No.14

Sports may be said to be worthy of note as essential contents that can lead the twenty-first century. Therefore, it seems of much significance to develop the sports industry to a new one in the twenty-first century inasmuch as it has been insufficiently developed for a commercial purpose. The results of this study were revealed, as follows: The potential of the growth of ths sports industry is considered an infinite entity as a prospective industry. Greater importance of sports as a new cultural propensity to consume. Development to a form of participatory sports with which production and consumption are combined. Attention be paid to changes in sports paradigms in which a variety of consumer-centered sports phenomena are expected. The enhancement of the commercial value of sports. Transition of mass sports to small-scale but varied individualized sports. Intensification of the personal welfare function of sports. The production of sports is shifted from a supplier-centered to a consumer-centered production. It would be an issue of importance to develop the added value of sports in knowledge base economy. The endlessly augmenting value of the contents of sports by dint of the rapid development of information technology. The development of the sports service industry is a global tendency. The cognition of the sports industry that has been thus far confined to sports articles manufacture and sports facilities is now rapidly growing. The emergence of the importance of sports services including sports information and sports marketing. The contribution of sports to the welfare and promotion of the people as a representative cultural industry. Sports-related business contributes to economic growth and acceleration of employment.

국내 석유화학 공업단지의 대기오염

이상권 한국외국어대학교 외국학종합연구센터 부설 기초과학연구소 1996 기초과학연구 Vol.5 No.-

국내 석유화학 단지의 대기오염의 현황을 살펴보기 위하여 우리 나라의 대표적인 대단위석유화학 공업단지인 울산, 여천, 대산 공단의 대기오염물질 배출현황과 대기오염도 현황을 비교 분석하였다. 공단별 대기오염물질 총배출량은 공단 규모와 직접적으로 연결되어 울산공단에서 가장 많이 배출되고 여천 공단, 대산 공단의 순위였다. 울산 공단의 대기오염도는 86년 이후 일부 항목 (SOx)이 한두 해 기준치를 초과한 것을 제외하고는 전반적으로 대기환경 기준치를 만족하는 수준이었으며 특히 대기오염 특별 대책 지역으로 고시된 이후 대기오염도는 전반적으로 개선되어 가는 경향을 보이고 있다. 여천공단과 대산 공단도 대기환경기준 항목인 SOx, NOx, TSP, CO의 농도는 전반적으로 기준치를 만족하고 있다. 그리하여 국내의 석유화학 공업단지에서 대기환경기준 항목인 SOx, NOx, TSP, CO의 농도를 살펴보면 우리 나라 석유화학 공단들의 오염도는 크게 우려되고 있는 상태는 아니라고 할 수 있다. 그러나 석유화학 공업단지에서의 오염도를 평가하는데 필수적인 항목이지만 현재 국내에서 규제되지 않는 휘발성 유기물질(VOCs:Volatile Organic Compounds)이 측정자료의 미비로 본 연구의 공단별 오염도 비교분석에는 포함되지 않았지만, 여천공단에서 측정된 자료를 살펴보면 이러한 휘발성 유기물질이 인근 주민들이나 근로자들에 대하여 미치는 유해성은 다소 심각할 것으로 예상된다. Air pollution in Ulsan, Yeochun, and Daisan industrial estates has been concerned by many people. This study focused to identification of the air pollution in the estates. Pollutant emissions from Ulsan industrial estates were much greater than from other estates. Annually averaged concentrations of pollutants in Ulsan area ranged within the air quality standards except SO₂. The concentration of SO₂in the estate is also getting decreased as its emission is regulated more strictly. The concentrations of SO₂, NO₂, TSP, CO, and O₃in both Yeochun and Daisan industrial estates were lower enough to satisfy the air quality standards. However communities near the estates has frequently complained of polluted environment and requested for the reduction of pollutant emissions or the movement of residential area. Major pollutants causing the social problem in the estates are not SO₂, NO₂, TSP, CO, and O₃, but volatile organic compounds(VOCs). Most of the VOCs emitted from the petrochemical plants are malodor us or carcinogenic pollutants, while their emissions are not regulated by the domestic laws yet. It is necessary to regulate the emission and the ambient concentration of the VOCs in a petrochemical estate in order to improve air quality.

이상권 경인여자대학 1993 경인논집 Vol.- No.2

본 논문은 企業環境變化에 대응하는 企業의 經營戰略的 變化를 새로운 情報의 欲求 요인으로 보아 이러한 變化가 管理會計시스템 설계시에 어떻게 고려하여야 하는 가를 고찰하고 있다. 주요한 企業의 經營戰略的 變化는 高品質, 底在庫, 유연적 유도라인, 工場自動化, 제품중심별 組織, 情報産業과의 상호 연계하여 변화되고 있으며, 또한 이들의 變化는 企業의 原價行態를 變化시키고, 새로운 情報欲求의 원인이 되어 전통적인 管理會計시스템에서 生産되는 情報는 目的適合性을 상실하게 되었다. 따라서 이들 環境變化에 의한 情報欲求의 變化를 분석하여 環境變化와 經營戰略의 변화에 유용한 管理情報를 生産할 수 있는 管理會計시스템을 설계하여야 한다는 주장을 하고 있다.
