Amorphous $MgNi_{1-x}Ti_x$ alloys with the composition of x=0.02, 0.03, 0.05 and 0.07 were synthesized by mechanical alloying. The synthesized alloys were investigated by electrochemical test, XRD and SEM. As increasing Ti concentration, the initial discharge capacity was raised more than that of nanocrystalline Mg-Ni 289 mAh/g, but the electrodes were degraded faster. Comparing to other synthesized alloys, $MgNi_{0.95}Ti_{0.05}$ alloy showed the highest initial discharged capacity 474 mAh/g and maintained $54\%$ of the initial capacity after 10 cycles.

The purpose of this study was to define 'sponsorship' as a kind of advertising tool, and to describe its effects on consumer brand attitude and actual purchase behavior. From previous research results, clothing sponsorship was defined as 'indirect advertisement', which has common ad traits as well as the uncommon ad traits, such as indirectness, emotional affinity, and symbolism. Results from empirical research using 1,227 data collected in Seoul and Kyounggi Areas were as follows ; (1) Television drama clothing sponsorship was proved to have effects on brand image, emotional & rational brand attitudes, decision making process, and actual purchase behavior. (2) Each of drama clothing sponsorship factors, such as 'drama', 'role', and 'actress', had different effects on brand memory and attitudes. (3) Consumer decision making process initiated by drama clothing sponsorship followed two different processes, which were called 'rational' and 'heuristic'. The rational process followed every steps of EKB model, which explained consumer's rational shopping, but heuristic model was closer to emotional and impulsive shopping.

The purpose of this study was to investigate the change of consumers' values as appeared in advertisements. Advertisements in men's magazine from 1976 to 1996 were classified by VALSI program. The results were as follows. 1. There was a significant trend that advertisements with outer-directed value decreased while the ones with inner-directed value increased. 2. In case of outer-directed group appeared in advertisements, There was a tendency that the hierarchy of needs shifted from emulators to achievers. However, the shift in hierarchy of needs in inner-directed group was not significant. 3. Even though the advertisements with material value were predominant, there was a tendency that the advertisement with material value decreased while the ones with human value increased.

This study was conducted to identify the characteristics of fatigue and its influencing factors in patients having chronic arthritis. The subjects of this study were 120 patients who visited a Rheumatis Center of H University Hospital. Data were collected from Aug. 9, 1997 to Feb. 5, 1998. For analysing data, SPSS/Win was used for descriptive statistics & Pearson's correlation coefficient, and Lisrel 8.0 was for path analysis. The findings were as follows : 1. Mean score of subjective fatigue was 5.36 and it means moderate degree of fatigue. 2. Fatigue showed positive relationship with pain & depression, and it showed negative relationship with ADL & self efficacy. 3. Fatigue was influenced by pain and depression. and was not influenced by ADL and self efficacy directly. But ADL and self efficacy influenced on fatigue through pain and depression indirectly. According to this findings. the significant influencing factors of fatigue were pain and depression, therefore the development of nursing intervention for relieving pain and depression would be needed.

The purposes of the study were to identify the general predictors of fashion leadership and to compare the fashion leadership predictors among different social groups. Thirty-one variables (thirteen fashion-related variables, five social variables, nine psychological variables, four demographic variables) were included in the regression analysis. Data were obtained from 446 women living in Seoul area by self-administered questionnaire. The results of the study were as follows: 1. Seven variables explained about 64 percent of the total variance of fashion leadership. The most important predictors of fashion leadership were fashion interest, use of marketer-dominated fashion information source, and 'stable-creative' self-image. 2. The predictors that consistently predict fashion leadership across different social groups (students, career women, housewives) were fashion interest and use of marketer-dominated information source. The predictors of innovativeness and opinion leadership were very different among groups.

This research was intended to provide conceptual framework of clothing conformity by determining motivation types of clothing conformity and nonconformity, and their relation-ships. The responses of 714 fulltime employeed subjects from four different cities were analyzed. Business were was used as the situational stimulus. The literature study suggested three different motivation types of clothing conformity including Normative Conformity, Informational Conformity, and Identificational Conformity, and two different types of clothing nonconformity including Anticonformity and Independence. As the results of the empirical analysis, clothing conformity types were found to be Normative Conformity and Identificational Conformity. Clothing nonconformity types were found to be Anticonformity and Independence. Identificatinal Conformity correlated positively with Anticonformity and negatively with Independence, whereas Normative Conformity correlated negatively with Anticonformity and Independence.

The main object of this study was to clarify the concept, scheme, an dimensions of the clothing evaluatie criteria, and to organize its theoretical framework accordingly. The research was carried out in tow ways. The first research was investigated by the critical evaluation of the existing literature, while the other research was investigated by an empirical survey study. The questionnaire was developed for the empirical study. The questionnaire was administered to 640 housewives living in Seoul area during the fall of 1988. Social wear was selected according to the defined times, place, and occasion. As a result of the literature study, the first research problem, the clothing evaluative criteria was loud to exist at three different level - benefit level, element level, and intemediate level -. The colthing evaluative criteria at the benefit le·eel were loud to include four different dimensions-fashionbility, status symbolism, practicality, and economy. The validity of the benefit dimensions was established by the empirical confirmation utilizing factor analysis technique.

This study is intended to help internet marketers by trying to segment consumer who had experience in buying clothing in internet shopping-malls. Concrete purpose of this study was 1)to segment by Buying Motives of Internet Clothing Buyer, 2) to identify demographic traits of segmented groups and 3) to identify buying behavior traits, internet shopping-mall choice criteria of segmented groups. The data of 500 respondents were collected by questionnaires in internet survey site. The results were as follows : 1) 5 factors; convenience, informational, hedonic, economic, easiness of refund were revealed by factor analysis, 2) 3 group types by buying motives; information-oriented, hedonic, convenience-oriented were identified by cluster analysis, 3) 3 groups were different in demographic traits, 4) goal-directed/experience-directed behavior and shopping-mall choice criteria of three groups were different. And then marketing implications were discussed.

This paper proposes a novel soft-switching interleaved boost converter composed of two shunted elementary PFC boost conversion units and an auxiliary inductor. This converter is able to turn on both the active power switches at zero voltage to reduce their switching losses and evidently raise the conversion efficiency and power factor. Since the two parallel-operated elementary boost units are identical, operation analysis and design for the converter module becomes quite simple. A laboratory test circuit is built, and the circuit operation shows satisfactory agreement with the theoretical analysis. The performance of the proposed PFC rectifier was evaluated on an experimental 300[W] PFC prototype.

This paper discusses the ZVS/ ZVZCS Three-Level converter using the minimum auxiliary circuit. A primary auxiliary circuit, which consists of one coupled inductor is added in the primary circuit to provide ZVZCS conditions to primary switches. ZVS is for outer switches and ZCS or ZVS is for inner switches. Many advantages including simple circuit topology high efficiency, and low cost make this converter attractive for high power applications. The principle of operation, feature and design considerations arc illustrated and verified through the experiment with a 2kHz 400kHz IGBT based experimental circuit.
