Many recent research reported that men, different from the past, want to represent their individualities through clothing and become important shoppers. The market for men is gradually extended. In this study, a well known relationship between clothing values and brand orientation were tested for male consumers. Data from 334 adult male consumers living in a metropolitan area were collected and analyzed. Results indicated that male consumers with various demographic characteristics such as age, marital status, income, and clothing expense showed different level of clothing values. Regression analysis results indicated that among hedonic clothing value factors, confidence in clothing and fashion orientation had significant influence on brand loyalty. Among utilitarian factors symbolic values expressed through clothing had a strong influence on brand loyalty of male consumers.

Zipper CMOS PLA 의 설계 및 테스트

이건기,한석붕,이문수 慶尙大學校生産技術硏究所 1988 生産技術硏究所論文集 Vol.4 No.-

In this paper, a new circuit type, the Zipper CMOS PLA, is described. Then a testable design and testing method for it will be discussed. The Zipper CMOS PLA has the regular structure of PLA and a NAND-NAND logic Zipper CMOS circuit. Therefore it incorporates all the advantages of dynamic CMOS circuit and array logic. In the testable design, feedback loops are formed in Zipper CMOS PLA by adding simple extra circuits. The oscillation, in test mode, occurs through the loops and can be observed at the outputs. By the proposed method, test application and evaluation are easy. The fault coverage is improved. The algorithms are also proposed, which add the extra circuits to the Zipper CMOS PLA and generate the test patterns. The validity of the designs is verified by performing the logic level simulation. Also the proposed algortithms are realized on VAX 11/750(UNIX) in C language.

김곤호,김건우,김영우,최영도,김종식,김상진,한승희,홍문표 漢陽大學校 工學技術硏究所 1998 工學技術論文集 Vol.7 No.1

Abstract- In a plasma source ion implantation, the target is successively biased by negative voltage pulses with an intrinsic finite rise time, resulting in the time-dependent sheath formation around the target. Measurement of time-dependent sheath during the pulse rise show the ion matrix sheath development which is in proportion to square root of time and pulse rise rate over plasma density but independent of the ion mass.

The objective of this study is aimed at reducing the contour error of AC Servo derives by improving the interpolation error of each axis through sliding mode control system. The errors in machining process by AC Servo motor are due to many elements, such as the delay of the servo drivers, friction and the gain mismatch between x axis and y axis motors and so on. Sliding mode control system is applied to a AC servo drive as a numerical example in this paper. The experiment results which are compared with those of typical PI scheme show the validity of improvement in circular interpolation error of the system.

시비방법별 벼 재배에 따른 전과정평가 방법을 적용한 환경영향 평가

신중두,임동규,김건엽,박문희,고문환,엄기철 한국환경농학회 2003 한국환경농학회지 Vol.22 No.1

Consoli가 설명한 것처럼 전과정평가의 개념 및 일반적인 정의에 따르면, 전과정평가는농업생산에 관련된 환경영향을 평가하는데 부합하는 방법이라고 생각되며, 특별히 전과정 평가방법인 Eco-indicator 95는 농업 체재에 대한 환경영향을 분석하는데 적절한 기법인 것으로 입정되었다. Eco-indicator 95 method를 이용하여 지구온난화 및 수계 부영양화와 관련된 시비체계에 따른 벼 재배에 대해 비교할만한 분석체계를 이루었다. 그렇지만 본 연구에서 전화정평가 항목에 기록된 모든 관련 정보가 환경 영향에 고려되지 않았기 때문에 Eco-indicator 95 method를 농업생산 체계에 적용할 때 몇 가지 난제에 부닥친다. Eco-indicator 95 method에 토양 및 자원의 이용과 같은 몇 몇 중요한 환경적인 문제가 포함되지 않았으며, 이 방법의 다른 문제는 환경 평가를 위하여 현장 정밀연구가 수행되지 않았다는 것이다. 그렇지만 본 연구에서 얻어진 생태지표 지수를 이용하여 벼 재배에 따른 시비방법 간의 차이점을 나타내기에 충분하다고 여겨지며, 가장 높은 생태지표 지수를 나타낸 화학비료를 시용한 구에서 가장 큰 환경영향이 관측되었고, 이러한 차이점은 주로 화학비료 투입에 의한 토양중의 높은 인산 함량의 축적 때문인 것으로 여겨진다. 분석한 시비체재는 특별히 지구온난화 보다는 수계의 부영양화의 환경적인 문제에 기여되는 것으로 나타났으므로 질소 시용비율 및 시용기술 이외에 액비 시용에 따른 양분 용탈이 수계 환경에 명확히 영향을 미치는 것으로 나타났다. The suitability of the Life Cycle Assessment (LCA) methodology to analyze'the environmental impact of rice cultivation with different fertilizing systems is investigated. The first part of an LCA is an inventory of parameters used and emissions released due to the system under investigation. In the following step, the Life Cycle Impact Assessment, the inventory data were analyzed and aggregated in order to finally get one index representing the total environmental burden. For the Life Cycle Impact Assessment (LCIA) the Eco-indicator 95 method has been chosen because this is well documented and regularly applied impact assessment method. The resulting index is called Ec -Indicator value. The higher the Eco-indicator value the stronger is the total environmental impact of an analyzed few system. The rice field experiment conducted in middle parts of korea was chosen as an example for the life cycle impact analysis. In this experiment the treatments were consisted of none fertilizer plot (NF), standard fertilizer plot (SF) applied chemical fertilizers based on soil chemical analysis before rice transplan ing, and efflux fertilized plot (EF) applied with pig wastes fermented as the same rates of SF plot as basis on total nitrogen content. The obtained Eco-indicator values were clearly different among the treatments in the rice trial. The total Eco-Indicator values for SF and EF have been observed 58 and 38% relative to the NF, respectively. For all the treatments the environmental effects of eutrophication contributed most to the total Eco-indicator value. The results appeared that the LCA methodology is basically suitable to assess the environmental impact associated with different fertilizer applications for rice cultivation. A comparative analysis of the fertilizing system's contribution to global warming and eutrophication is possible.

金浩植,金鍾大,金在根,韓文洙 嶺南大學校附設 基礎科學硏究所 1986 基礎科學硏究 Vol.6 No.-

Malachite Green derivative bearing butyl group was prepared in the form of Leuco base, 4-butyl-4'. 4"-bis(dimethylamino) triphenylmethane, by the condensation reaction of N,N-dimethylaniline with the formyl derivative of butylbenzene, which had been obtained from butylbenzene by chlormethylation followed by oxidation. The butylbenzene was prepared by the alkylation reaction of benzene with n-butyl choride which had been obtained from n-butyl alcohol and zinc chloride. The antimicrobial and antifungal activity of buty-Malachite Green was evaluated in terms of minimum inhibitory concentration by the dilution method. The butyl-Malachite Green showed considerably increasing activity. This activity was stronger than that of hexyl-Malachite Green. This phenomenon suggested that the activities of the alkyl derivatives increase with decrease in the number of carbon in the alkyl group.

This study aims to review current research on Korean vocabulary and to synthesize the findings based on main points of vocabulary research. With this purpose, this study selected various articles from four major journals published in Korea. A total of 30 vocabulary-related articles in the journals published after 2000 were reviewed and analyzed in terms of the following three perspectives, teaching and learning; assessment and the relationship between other language skill. And this study show that the majority of the research has been conducted on vocabulary teaching and learning among these domains. There were conflicting results of the effects of using implicit and explicit approaches to vocabulary teaching and learning. There is also a dire need for teachers to develop students vocabulary learning strategies. Various factors affecting students' vocabulary competence are examined for effective vocabulary teaching and learning. Considering the current trend of various views in language teaching more balanced vocabulary research in terms of topics should be conducted in the future. Several implications and applications are discussed based on the findings of the study. (Pusan National University)

Supersonically sprayed clay, silica, and silica aerogel hybrid films as thermal and electrical barriers

Kim, Tae-Gun,Park, Chan-Woo,Lee, Jong-Gun,Kim, Min-Woo,Choi, Mun Seok,Kim, Woo Yeong,Yang, Jae Sin,Yoon, Sam S. Elsevier 2018 CERAMICS INTERNATIONAL Vol.44 No.11

<P><B>Abstract</B></P> <P>A thermal barrier coating (TBC) provides protection from thermal damage. While sufficiently thick coatings facilitate thermal protection, space limitations often require the use of high-performing barrier materials, such as clays, silica, and aerogels. Herein, we demonstrate the fabrication of thin TBCs of clay, silica, and silica aerogel microparticles deposited by supersonic cold spraying. The coated films were characterized by scanning electron microscopy and transmission electron microscopy. The effects of varied coating thicknesses from 1 to 5 mm on the TBC performance of each material were studied for both heating and cooling scenarios. We found that the hybrid clay–aerogel coating provided the best thermal insulation. Deposition by supersonic cold spraying is rapid and scalable, with potential applicability for the commercial production of TBCs.</P>
