Using back electro-motive force(EMF) signals of a brushless DC motor, the sensorless micro-processor controlled drive system was developed. In this new commutation method, the manual pulses are used for relatively short accelerating phase and then the exact commutational positions are detected based upon the back emf signals. The hardware and software implementations with the experiment to compare the performance of the developed system with the, conventional system using hall effect sensors are included. By reducing the number of the required sensors in the artificial heart control system, the total reliability will be incresed.

This paper presents the efficient 2-D linear brake analysis model which can compensate the lateral leakage flux by changingng the airgap length and magneto-motive force(MMF). The linkage flux of the 2-D analysis is larger than that of 3-D analysis. This is caused by the assumption in 2-D analysis that geometric and physical values are constant along the perpendicular direction(z) to the analysis region. The equivalent MMF have been calculated from the linkage flux difference between the 2-D and 3-D analyses which are performed at zero velocity. The performances of the linear brake have been analyzed effectively by using the compensated 2-D models without using 3-D FEM.

Purpose: The purpose of this study was to identify and compare role conflict and job satisfaction between nurses in ICU and nurses in general ward. Method: The subjects of this study consisted of 141 nurses employed at ICU and 201 nurses employed at general ward, who were recruited from 5 university hospitals with 500 beds located in Seoul and Gyeonggido. The instruments included role conflict scale developed by Kim and Park(1995) and job satisfaction scale translated and modified by Lee(1996). The collected data were analyzed using the SPSS WIN 10.0 program for descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient. Result: In the two groups, there was a inverse correlation between role conflict and job satisfaction. In ICU, nurses' role conflict levels differed significantly depending on religion(p<.05), total experience(p<.05), scheduled to work as a nurse(p<.05). And nurses' job satisfaction levels differed significantly depending on total experience(p<.05), working period in current post(p<.001), scheduled to work as a nurse(p<.001), motive of choosing the nursing science(p<.01), and job satisfaction(p<.001). In general ward, nurses' job satisfaction levels differed significantly depending on marital status(p<.05), educational level(p<.01), total experience(p<.001), motive of choosing the nursing science(p<.01), and job satisfaction(p<.001). Conclusion: Summing up, the nurses at ICU showed higher level of role conflict than the nurses ay general ward. Therefore, it is needed to decrease the level of nurse's role conflict and improve their job satisfaction in ICU.

제품이나 서비스에 대한 사용후기 중에는 과격한 표현이 포함되거나 사업자에게 불리한 내용이 포함된 것들이 많아서, 후기 작성자와 사업자 간에 마찰이 빚어지거나 심지어 법률적 분쟁으로까지 이어지는 경우가 많다. 본 연구는 부정적이고 과격한 표현이 담긴 사용후기관련 사례를 분석한 후, 사례에 나타난 사용후기에 대한 소비자들의 윤리적, 법률적 인식을 비교하기 위해 설문 조사를 실시하였다. 사례연구에 따르면, 대법원 판례는 행위자의 주요한 동기나 목적이 공공의 이익을 위한 것이라면 부수적으로 다른 사익적 목적이나 동기가 내포되어 있더라도, 후기 작성이 상대를 비방할 목적이 있다고 보기 어렵다고 판시한 바 있다. 사례 요지를 바탕으로 소비자들의 인식을 조사한 결과, 사업자에게 불리한 내용의 사용후기일지라도, 응답자들은 대체로 작성자의 법률적 책임수준보다는 이러한 행위에 대한 지지수준이 더 높은 것으로 나타났다. 구체적으로, 이러한 사용후기는 공공의 이익을 위한 정보제공에 더 큰 의미가 있으며, 특히 소비자에게 정확한 정보를 제공하기 위해서 허용되어야 한다는 의견이 우세해서, 연구대상 사례에 대한 대법원 판결과 맥락을 같이 하고 있다. 결론적으로, 사용후기에 대한 윤리의식과 함께 법률적 책임의식을 향상시키기 위한 정책적 노력이 병행될 필요가 있으나, 표현의 자유가 과도하게 침해되지 않도록 균형을 이루는 것이 중요하다.

본 연구는 보험소비자의 자발적 구매동기가 보험소비만족에 어떠한 영향을 주는지 확인하고자 하였다. 심리학의 자기결정성 이론에 근거하여 자발적인 구매동기를 유발하는 소비자의 심리적 욕구를 포함하여 보험소비만족에 대한 직 간접적 영향을 파악하고자 하였다. 보험소비자 1,225명 대상의 온라인 설문조사 자료를 이용하여 구조방정식 분석을 통해 연구 가설과 모형을 증명하였다. 연구결과, 소비자가 구매의 필요성을 스스로 인지하는 자발적인 구매동기에 의한 구매시 보험소비만족이 높아지고, 보험소비자율성과 보험소비환경에 대한 긍정적 인지는 자발적 구매동기를 높이며, 이를 매개로 소비만족에 기여하는 것으로 나타났다. 본 연구를 통하여 보험회사의 과도한 마케팅과 보험소비자의 자기과신은 보험소비만족을 저해할 수 있으며, 보험소비자의 자율적권리와 책임 인식을 높이는 금융소비자의 소비태도 교육이 필요하다는 시사점이 도출되었다.

본 논문은 디지털교과서에 대한 태도요인이 학습흥미도와 학습만족에 미치는 영향에 대하여 연구하였다. 이러한 연구를 위해 현재 디지털교과서 연구시범학교에서 학습에 참여하고 있는 학습자 325명으로부터 자료를 얻어 실증적 연구를 수행하였다. 특히 디지털교과서에 대한 태도요인을 교과에 대한 자아개념요인인 우월감, 자신감요인과 교과에 대한 태도요인으로 흥미, 목적의식, 성취동기요인으로 세분화하여 살펴본 결과 자신감, 흥미, 목적의식, 성취동기요인이 학습흥미도에 유의미한 영향을 주었으며, 또한, 이들 태도요인에 따른 학습흥미도는 학습만족에도 유의미한 영향을 주는 것으로 나타났다. 이러한 연구 결과를 통해 앞으로 디지털교과서의 상용화에 대비하여 학습자의 디지털교과서에 대한 태도요인을 고려하여 콘텐츠 설계 및 제작이 이루어져야 할 것이며, 콘텐츠 구성면에서도 학습흥미도를 고려하여 풍부한 학습내용 및 다양한 피드백 경로 제공 등을 통해 학습만족도와 학습성과를 높일 수 있음을 시사하고 있다.

The purpose of this study was to identity the relationship of clothing involvement, consumer characteristics, and clothing buying behavior of college female students in China. A questionnaire was developed to measure clothing involvement, materialism, conspicuous consumption, reference group influence, clothing purchasing modes, fashion information sources. The questionnaire was administered to 390 college female students in Dandong of china. The data were analyzed using percentage, frequency, factor analysis, and t-test. The results of the study were as follows: 1. Subjects were divided into low clothing involved and high clothing involved groups according to the level of clothing involvement. 2. Three dimensions of materialism were derived by factor analysis such as Happiness-pursuing, Life-centered, and Sucess-symbolic. And three dimensions of conspicuous consumption and reference group influence were derived by factor analysis such as luxury oriented, Status symbolic, Brand-name oriented, and Comparative, Informational, Normative exactly. Clothing purchasing motives and fashion information sources were factor analysed as Social and Individual mole, and Printed & Electric-wave media, Marketer managed, Personal exactly. 3. There were significant differences between high involved and low involved consumers in consumer characteristics and clothing purchasing behavior. The high involved consumers showed more importance than low involved consumers about materialism especially in Happiness-pursuing about conspicuous consumption in status symbolic and about influence of reference group in comparative. The high involved consumers put more importance than low involved consumer individual motive as clothing purchasing motive, and marketer managed in clothing fashion information. The high invoked consumers showed more importance than low invoked consumers about evaluating attributes of product, and about store patronage criterion.

This study proposes the use of firework shapes to design fashion accessories in the judgment that they are appropriate for the expression of creative images in consideration of the display of fireworks as a kind of entertainment and a festive symbol. This study promotes the sustainable application of firework shapes to develop the designs of fashion culture items that feature a distinctive personality and uniqueness. In this present study, the proposed fashion accessory design was intended to create an entertaining new atmosphere that uses an Organic Light Emitting Diode (OLED) that draws attention as a futuristic display. In terms of methodology, a literature review of firework shapes and OLED was conducted; in addition, Adobe Illustrator CS2 and Adobe Photoshop CS2 were used to develop six different standard motive designs with formative design elements represented by a variety of firework shapes. Each of the six motifs was further expanded with different color combinations. Rich images are produced with the use of pink, blue, purple, green, yellow, orange, and red, in conjunction with various OLED effects to express the three-dimensional images of fireworks. The motifs are applied to three types of items: bags, bracelets, and necklaces. For the video images, evening and tote bags, pendants, and bangles were used. Shifting images and lights should produce unique images as well as satisfy the consumer desire for entertainment. The Adobe Image Ready software was used to present the motive of fireworks applied to the design of fashion accessories in video images but not in still-cut images due to physical constraints of this paper.
