The purpose of this study is to find out effective ways to take care of the 8th and 10th graders' disposition causing math. disliking. To accomplish this goal, we proceeded as follows : First we categorized the 11 factors recognized as the reasons of math. disliking into 4 math. disliking causes such as psychological f: environmental cause, conceptual cause, relational cause and application related cause. Second, to take care of these tow causes, we developed materials which are closely related with the contents of the 8th and 10th graders' school mathematics. Third with these materials we taught the students who had proved to have the math. disliking trend, for one semester. As a consequence of this experiment we arrived at the following results. As for psychological & environmental causes, 35.7% of the 8th graders and 17% of the 10th graders proved to have been improved significantly. This result shows that the curing of the psychological & environmental causes is more effective in the 8th graders than in the 10th graders. i.e., the curing effects of the students' psychological & environmental cause for disliking math. decline as they get older. As for conceptual causes, 35% of the 5th graders and 30% of the 10th graders proved to have been improved significantly. In case of the 8th graders this ratio was similar to that of the other causes. But as for the 10th graders this ratio was a little low compared with that of the case of relation causes and application related causes. As for relational causes, 35% of the 5th graders and 49% of the 10th graders proved to have been improved significantly. Especially the 10th graders improved greatly. Among the four factors that compose this cause, especially hierarchy and connection factors were effectively cured. On application related causes, 47% of the 5th graders and 57% of the 10th graders proved to have been cured significantly. And among the four types of causes listed above, this was the most successfully cured one. Of the two factors of this cause, the basic application factor appeared to have been improved in all experimental groups. In connection with teaching methods, we found out the followings two facts. First, the more teachers push students to solve their tasks with their own efforts, the higher is the ratio of owe. Second, the more teachers teach students personally, the more effective are the teaching results.

Since self-efficacy was suggested by Bandura(1977) as the most important factor that affects human behavior, preceding studies about self-efficacy are frequently related with children, and it is a main stream that only personal factors are chosen as related factors of these studies. Considering we don't have enough studies about family factors that reflect qualitative and relational factors of adolescents' home background, this study was aimed to seize the actual condition of self-efficacy meaning perceived and emotional faith about their own ability. These are our major concerns: 1. What kind of tendency does self-efficacy and appearance stress of adolescents, family functioning show? 2. How strong are relative influences of variables on self-efficacy of adolescents? This study was operated on July and August, 2002, aimed 378 middle school and high school students in Jeon-Nam, Mokpo area. 378 question sheets were used for analysis. Followings are results of this study. First, aimed students' average mark of self-efficacy was 2.09, which meant a normal level. And in low-ranked part, self-control-efficacy was the highest, and confidence task difficulty preference was following. Furthermore, whole self-efficacy showed a little difference from the demographic factor of adolescents. In low-ranked part, however, confidence and self-efficacy showed a somewhat difference. As students grew up, confidence decreased, and male students showed higher self-control-efficacy than female ones. Second, appearance stress and family functioning degree had a strong relation with self-efficacy. Family functioning, had important interrelation not only with whole self-efficacy but also with low-ranked part of self-efficacy. In low-ranked part, self-control-efficacy and task difficulty preference were proportional to the family functioning degree. From these results, we can find that the appearance stress was an actual factor that affected the self-efficacy of adolescents, and their self-efficacy was strongly related with family functioning degree. Accordingly, affirmative emotion in family, harmonic communication among family members and sharing housekeeping works had an immediate influence on elevation of self-efficacy.

This study investigated the impact of long-term relationship orientation on emotional characteristic in fashion stores and relationship characteristic between middle-aged and senior women and salespeople. This study employed survey method with questionnaire. Data were collected from 579 women who were from the age of forty to seventy. The data were analyzed using statistic methods(SPSS 15.0 and Amos 5.0) such as frequency analysis, cronbach $\alpha$, exploratory factor analysis, second-order confirmatory factor analysis, confirmatory factor analysis and structural equation modelling. The findings of this study were concluded as follows; Firstly, the income significantly affected on emotional characteristics(p < 0.01), but had no significant effect on long-term relationship orientation(p < 0.05). The higher income, the more respondents exhibited positive attitude and sensitive emotional characteristics as a sense of sight, hearing, smell, tactile and feeling to salespeople in the fashion stores. The path of structural equation was implemented as income variables $\rightarrow$ emotional characteristics $\rightarrow$ (relationship with salespeople variables $\rightarrow$ )commitment $\rightarrow$ long-term relationship orientation which turned out to be statistically significant at the 95% confidence level. Secondly, senior group(55~70yrs) was more positive relationship with salespeople compared to middle-aged group(40~54yrs). The precondition of get satisfaction and feeling of being cared from the salespeople were critical for long-term relationship orientation. The path of structural equation was carried out as age variables $\rightarrow$ relationship with salespeople variables $\rightarrow$ commitment $\rightarrow$ long-term relationship orientation which turned out to be statistically significant at the 95% confidence level.

As a major obstacle to active online purchase at the level of consumer in China, distrust is raised in this study. Most of previous studies showed that trust is a major variable to cause a relational unity between company and consumer, on the other hand, this study attempts to show that according to the two dimensional point of view regarding trust each dimension of both trust and distrust distinctly contributes to marketing achievement. Interaction, perceived popularity, information usefulness, perceived security risk and perceived dealing risk were created as preceding variable, trust and distrust were constituted as parameter and relation absorption and purchase intention as consequential variable. These variables were analyzed with structural equation modeling (SEM) in LISREL 8.3 program. The results for this study are as follows. First, relation between exchange actors in marketing is divided into two concepts of trust and distrust differently from the previous studies. On the assumption that trust and distrust might exist simultaneously and they would distinctly have an influence on marketing consequency such as relation absorption and repurchase intention, it is identified that trust and distrust are a different dimension in online context. Second, the formative factor of online trust-distrust is identified and it is shown what relationship between internet shopping mall and relation absorption and foregoing purchase intention resulting from online trust-distrust exists. Third, it is shown that in online context the formative factor of online trust-distrust is distinctly contributed to relation absorption and repurchase intention. It is suggested that trust needs to be managed two-dimensionally separating from trust and distrust. Fourth, it is shown that both trust and distrust factor in terms of relation absorption and repurchase intention of consumer in internet shopping mall are significant variables. Trust is linked with repurchase intention through relation absorption, however, distrust is not directly linked with repurchase intention through relation absorption. Thus, the ripple effect of distrust appears to be much higher than that of trust.

본 연구에서는 관리형 유통경로의 구조적 요인들인 공급자 특유투자, 커뮤니케이션, 소매상 의존도가 신뢰에 미치는 효과를 검토하고자 하였다. 또한 이러한 변수들에 대한 관계수명주기의 조절효과를 밝히고자 하였다. 관계적 거래는 하루아침에 성사되는 것이 아니라 장기간에 걸친 반복적 거래 및 사회적 맥락(social context)이 누적된 결과로 발생하기 때문에 관계마케팅을 성공적으로 수행하기 위해서는 관계수명주기에 대한 단계별 검토가 우선되어야 한다. 작물보호제 소매상 296명으로부터 설문자료를 수집하여 분석한 결과, 공급자에 대한 소매상의 의존도가 신뢰를 가장 크게 증가시키는 것으로 나타났다. 특히 관계가 발전할수록 의존도의 영향력은 점점 더 커졌다. 따라서 공급자는 차별화된 제품과 서비스를 제공하여 시간의 흐름에 따라 소매상의 의존도가 더욱 높아질 수 있도록 노력해야 한다. 그리고 공급자 특유투자는 관계 초반에 신뢰를 증가시키는 역할을 하는 것으로 나타났다. 반면에 성숙기 이후에는 유의한 영향력을 보여주지 않았다. 이는 관계 초기에는 상대방을 평가하는 단서가 특유투자에 불과하기 때문에 특유투자의 효과가 크게 나타나지만 관계가 발전하면 상대방을 평가할 수 있는 여러 가지의 단서를 획득하게 되어 특유투자의 효과가 적은 것으로 볼 수 있다. 또한 양자간의 커뮤니케이션은 신뢰를 높여주는 것으로 나타났으며 신뢰는 장기지향성에 긍정적인 영향을 미치는 것으로 나타났다. 성숙기보다 강화기에서 커뮤니케이션의 영향력은 더 크게 나타났다. 본 연구는 관리형 시스템의 관계변수인 공급자 특유투자, 소매상 의존도, 양자 간 커뮤니케이션을 통합적으로 검토하였다는 점에서 의의를 찾을 수 있다. 그리고 관계수명주기의 조절효과를 검토함으로써 관계의 발전단계에 따른 차별적 전략을 제안할 수 있었다.

A district heating(DH) system supplies environmentally-friend heat and is appropriate for reduction of energy consumption and/or air pollutions. The objectives of this paper are to systematize data processing of transition temperature, investigate its effects on fatigue life of DH pipes and optimization for size of DH pipes. A relational database management system as well as reliable fatigue life evaluation procedures is established for Korean DH pipes. Also, since the prototypal evaluation results satisfied both cycle-based and stress-based fatigue criteria. Through the optimum design process, the cross section diminished 18.64% and the CUF diminished 23.35%. So, it can be used as useful information in the future for optimal design, operation and energy saving via setting of efficient condition and stabilization of water temperature.
