The deepening of competition in the airline industry made the motive to evoke the quality management which emphasizes the quality side in the airline service. Espesially, in the service the fact that the customer's loyalty extent is desided buy how the dissatisfaction than satisfaction is dissolved, the complaint which customers feel is controlled and deserved and repurchase intention become higher means the treatment of complaint behavior of dissatisfied customers became key factor in the customer management. Customers have five fundamental alternatives when they have dissatisfied with a purchase or some aspect of it; take no action, discontinue use of the service, tell friends and others about their problem, complain to cabin manager, complain to sort of consumer protection group and KNTO(Korea National Tourism Organization) For the reserch, this study collected 240 questionnaires targeted to native passengers who come to Korea at the Inchon international airport terminal and set up five hypothesis and used muitiful regression analysis, paired-sample T-test, crosstabulations analysis. According to survey, 1st, Evaluation factor of cabin service quality is positively related to customer's satisfaction. 2nd, There is significant difference between the attribution of cabin service quality and subject of dissatisfaction. Specially, They are dissatisfied by the human professionalism such as cabin crew's clean appearance, courteous cabin crew, pertinent service procedures. 3rd, Dissatisfied passengers than satisfied passengers show strong complaint behavior. 4th, Rutine object passengers than object passengers show strong complaint behavior. 5th, Dissatisfied passengers using national airlines were more likely to refuse to use them again than those using foreign airlines. As a result of the reserch, it could be helpful for the airline industry to establish marketing strategy by understanding dissatisfied factors and complaining behaviors of airline passengers. Finally, Airline management should make more efforts to improve service quality.

삼백초(Saururus Chinensis (Lour.) Bail)열수추출물의 항암활성 검색을 위하여 여러 암세포에 대한 저해효과와 항산화효과를 측정하고 발암물질인 MNNG를 투여한 동물조직내의 항산화 효소 활성변화에 미치는 영향 등을 살펴보았다. 그 결과 삼백초 열수추출물은 특히 혈액암 세포인 U937에 대해 가장 높은 저해 활성을 나타내었고, 또한 Chinese hamster V79 cell을 이용한 H2O2로 유도된 세포독성에 대한 억제효과도 나타내었다. 그리고 삼백초 열수추출물은 MNNG를 투여한 다음 감소된 glutathione S-transferase와 superoxide dismutase의 활성과 glutathion의 함량을 높여주었다. 이상의 결과로 삼백초 열수추출물은 항산화에 관련하여 발암을 예방하리라 사료된다. Chemoprevetion effects of Saururus Chinensis (Lour.) Bail water extracts on several tumor cells, Chinese hamster V79 cells and antioxidant enzymes in Wistar male rats were investigated. The water extracts of Saururus Chinensis (Lour.) Bail showed a higher cytotoxicity effect on the human histiocytic leukemia cells(U937) and protective effects against the cytotoxicity of H2O2. The glutathione content was decreased by MNNG treatment but was increased by adding Saururus Chinensis (Lour.) Bail water extracts. Also the activities of glutathione S-transferase and superoxide dismutase were increased by the treatment of Saururus Chinensis (Lour.) Bail water extracts more than with MNNG alone. These results suggest that the water extracts of Saururus Chinensis (Lour.) Bail inhibit the growth on U937 and has a protective effect on liver and stomach damage by the activities of free radical generating enzymes.

The purpose of this study was to develop a wearable platform system that can detect and acquire a soldier’s biosignals (i.e., heart activity signal, respiration rate, etc.) in a nonrestrained, unconscious manner. These detected biosignals are transmitted to a processing device to analyze and monitor the soldier’s physical status. To achieve this, textile-based heart activity electrodes and a strain gauge sensor for the respiration signal measurement were developed, and their performances in detecting each signal were verifed. These sensors were embedded in a chest belt to design a wearable platform that can simultaneously measure heart activity and respiration signals. The sensor part of the chest belt has a dual layer structure to detect high-quality signals. Stretch fabric was used on the outer layer and a respiration sensor was attached to the belt. On the inside layer, a non-stretch fabric was used as the base fabric and a heart activity-sensing electrode, that is capable of taking measurements using a modifed lead-II heart activity signal induction method, was embroidered onto the fabric. Subjects were asked to wear the chest belt, and a biosignal processor module was attached to verify the system’s performance while simultaneously acquiring the heart activity and respiration signals. More specifcally, it was confrmed that the two signals were detected in a stable. It is expected that the biosignal-monitoring wearable platform system developed in this study will be able to efectively analyze and monitor soldiers’ biosignals.

The purpose of this study is to analyze differences in between neighborhood satisfaction of apartment residents in five Newtowns. To accomplish this aims, the 361 samples of the apartment residents were partially used from the que.stionnaire data surveyed for a study on the housing consumption behavior of the Metropolitan area by KRIHS (Korea Research Institute for Human Settlements) in 1999. To data analysis, descriptive statistics, t-test, one-way ANOVA, Duncan test, factor analysis, crosstabulation analysis, correlation and multiple regression analysis were performed with the SPSS Win program (Ver. 10. 0). Conclusions are as follows : 1. The apartment residents in five Newtowns were mainly in thirties and forties and in the level of a white-collar worker (office worker). The greater part of this sample possessed their own house and its size was large-sized with a room of four. 2. The present neighborhood satisfaction of the apartment residents in Newtowns was 3.56 points. The eight factors (Traffic facilities, Green space, Educational facilities, Neighborhood facilities, Cultural facilities, Participation condition, Financial condition and Public services) of neighborhood satisfaction were between 3 and 4 points. Household characteristics and housing characteristics did not have an significant effect on the neighborhood satisfaction. But the residential town had an effect on it. Residents in Bundang were satisfied much more than other towns (Chungdong, Ilsan, Pyongchon, Sanbon) with Traffic facilities, Green space, Neighborhood facilities, Cultural facilities, Participation condition and Financial condition. Bundang considered residents more than other Newtowns in six aspects. Residents in Chungdong were satisfied with Cultural facilities. Residents in Sanbon were satisfied with Traffic facilities, Educational facilities and Financial condition.

빠르게 변하는 정보화 사회에서 방대한 양의 문서 정보를 전자 문서로 만들고 관리하는 것은 필수적이다. 이러한 전자 문서를 표현하는 데 있어서 사용하는 문서 내에 포함된 모든 정보를 손실 없이 저장하고 관리하는데 적합한 언어가 전자 문서의 표준인 XML이다. 본 논문에서는 문서의 변경이 발행한 경우에 문서 전체가 아닌 변경이 발행한 내용만 버전을 부여하고 저장함으로써 저장 공간을 절약하였다. 그리고 문서의 변경 내용이 일정한 크기 이하이면 JOIN 연산을 생략할 수 있도록 시스템을 설계함으로써 JOIN연산으로 인한 시스템의 성능 저하를 줄여 효율적인 XML 문서 저장과 빠른 검색 및 버전 관리가 가능한 방안을 제시하고, 이를 적용한 문서 저장 관리 시스템을 구현하였다. In rapidly changing an information=oriented society, it is essential to control massive document information by electronic file, In relation to these electronic document, it is also important to keep and maintain all kinds of information without any losses. It should be allowed to trace previous contents as well as recently updated contents by controlling updated contents with version. For these, XML is recommendable. In this thesis, we intend to save the document storing space by saving only updated contents with version without saving whole documentation, when document is updated. In case of controlling the history of document update by version, we designed system so as to omit “JOIN operation” if document size is under a certainspecific size. Therefore, we implemented a new XML document repository system which is possible for quick search and efficient XML document saving by reducing perfomance deterioration caused by JOIN operation.

The Most powerful tools in the synthetic organic chemists arsenal are organometallic compounds and metal mediated transformations. We reported a general approach for highly reactive metal powder by reducing metal salt in tetrahydrofuran solvents using lithium as reducing agents. Organometallic compound was generated by reaction of metal powder with organo compounds and then it was reacted with α ,β -unsaturated ketone. We synthesized 3-(4-chlorophenyl ) -1- (2-thienyl)ethylpropenoate, ethyl- (2-cyano) -3- (thienyl ) -propenoate and ethyl-(2-cyano)-3-(4-chlorophienyl)-propenoate, which are α , β -unsaturated ketone derivations. Magnesium chloride react with Li+Naph-r to give activated magnesium. The synthesized activated magnesium metal reacted with sec-Butylmagnesium chloride and n-Butylmagnesium bromide to give alkyl magnesiumhalide. The active amyl magnesium derivation reacted with the synthesized α , β-unsatruated ketone to give product.

김동현,박주양 漢陽大學校 環境科學硏究所 2003 環境科學論文集 Vol.24 No.-

전기로 슬래그의 재활용을 위해서는 우선적으로 환경적 안정성이 검증되어야 한다. 본 연구에서는 aging 처리한 전기로 슬래그의 환경 안정성을 availability test와 ANC test를 통한 단기평형 용출과 장기용출 거동을 조사하였다. 또한 모델링을 통해 단기평형 용출실험의 결과와 비교할 수 있었다. 실험결과 공기 중 aging을 수행하는 것은 산중화능을 증대시켜 환경적으로 안정성을 높이는 방법이라 판단된다. 또한 장기용출 실험결과 L/S ratio가 작은 경우 전기로 슬래그 자체의 높은 pH에 의해 반응기 내부의 pH가 영향을 받게 되어 용출된 중금속의 양은 매우 미량이였다. ANC test와 availability test의 결과는 MINTEQA2를 이용한 모델링과 비교되었으며, 전기로 슬래그에 대한 용출특성이 모델링을 통하여 예측 가능할 것으로 판단된다. It is important to comfirm environmental stablity of electric are furnace(EAF) slag which has a low recycling ratio due to expansibility and breaking-down-possibility. The objective of this study is to investigate the environmental stability of EAF slag through availablity test, ANC test and long-term leaching test. Modeling data was compared with the result of short-term equilibrium leaching test. The results of ANC test and availability show Processing aging in the air is the way to increase environmental safety by enhancing acid neutralizing capacity. And result of long term leaching experiment shows that increasing L/S ration of almost every heavy metal at the same flow increased amount of leaching. Compared the results from ANC test and availability test to result of copying by MINTEQA2, each deposit curve of objective materials copied by MINTEAQ2 corresponds to the test results, and that is effective to predict leaching properties of EAF slg.
