High school is regarded as the period when many important physical, mental and social developments occur, and when many health-related behaviors are formed. School health education is one of the major learning resources influencing health potential in the home and community as well as for the individual student. High school health education in Korea has a fundamental systemic flaw however, in that health -related subjects are divided and taught under various subjects at school. In order to achieve quality health education, it is essential to assess the learners' and teachers' educational needs. So far, most of the research projects that had been carried out for improving high school health education were limited to only the learners' educational need. They failed to in elude an educational assessment of the teachers. Therefore, in this study the high school health education teachers' needs relating to health education were investigated through a focus on the teachers' health education activity level, health education activity self-efficacy level, and perceived level of importance in health education content. In this study, research instruments these factors were constructed by Yoo(1997) on the basis of the PRECEDE model. The data for this study were collected from a sample consisting of twenty general and vocational high schools in Seoul and Chongju for a two month period beginning in July, 1996. In analyzing the data, an ANOVA test and stepwise multiple regression were accomplished using an SPSS - PC+ program. The results were as follows: The average level of health education activity and self-efficacy among high school health edu cation teachers were found to be low. But, teachers' perceived importance of health education contents was high. Teachers' activity and perceived importance concerning sex education were lower than in other health education areas. Health education activity of Military drill teachers was higher than that of physical education teachers as well as school nurses. But it was not significant. Health education activity self-efficacy of school nurses was higher than that of other teachers(p<.05). Perceived level of importance of health education contents was the most influential variable in teachers' health education activity. Health education activity self-efficacy level was not an influential variable in teachers' health education activity. The significance of this study is that it has diagnosed the needs of high school health education through the teachers' assessment of a variety of health factors related. These findings suggest that the management of an integrated health education, program requiring large changes in the curriculum of health education is necessary.

본 연구의 목적은 우리나라의 대표적 환경축제인 함평나비축제를 대상으로 환경축제가 지역주민의 충성도 제고라는 측면에서 지향해야 할 방향과 과제를 모색하는 것이다. 이에 지역주민을 대상으로 지역사회 애착도와 같은 축제의 외생적 요인과 축제의 경제 효과, 개최자와 지역주민 간의 의사소통, 그리고 지역주민의 축제 참여의사 같은 내생적 요인이 축제의 만족도 및 충성도에 미치는 영향과 경로를 구조 방정식모형을 통해 분석하였다. 분석 결과 애착도, 참여의사, 의사소통은 축제의 만족도에 정(+)의 영향을 미치고, 이 중 애착도는 충성도에도 정(+)의 영향을 미치며, 만족도는 충성도에 정(+)의 영향을 미칠 것이라는 본 연구의 가설은 유의수준 0.05에서 통계적으로 유의한 것으로 판명되었다. 다만 경제 효과는 연구가설과는 달리 만족도에 별다른 영향을 주지 않는 것으로 분석되었다. 한편 충성도에 미치는 총 영향력은 애착도, 의사소통, 참여의사 보다 만족도가 월등히 높은 것으로 나타났다. 그러므로 충성도 제고를 위해서는 원천적으로 애착도 제고, 의사소통 활성화, 참여의사 제고가 긴요하겠지만 이는 장기적으로 꾸준히 추진해야 할 과제일 것이며 단기적으로는 무엇보다도 만족도 제고에 노력하여야 한다.

This study is about comparing coal thermal plant to LNG combined power plant in respect of environmental and economic cost analysis. In addition sensitive analysis of power cost and discount rate is conducted to compare the result of change in endogenous and exogenous variable. For environmental assessment, when they generate 10,669GWh yearly, coal thermal power plant emits sulfur oxides 959ton, nitrogen oxide 690ton, particulate matter 168ton and LNG combined power plant emits only nitrogen oxide 886ton respectively every year. Regarding economic cost analysis on both power plants during persisting period 30 years, coal thermal power plant is more cost effective 4,751 billion won than LNG combined taking in account the initial, operational, energy and environmental cost at 10,669GWh yearly in spite of only LNG combined power plant's energy cost higher than coal thermal. In case of sensitive analysis of power cost and discount rate, as 1% rise or drop in power cost, the total cost of coal thermal power plant increases or decreases 81 billion won and LNG combined 157 billion won up or down respectively. When discount rate 1% higher, the cost of coal thermal and LNG combined power plant decrease 498 billion won and 539 billion won for each. When discount rate 1% lower, the cost of both power plant increase 539 billion won and 837 billion won. With comparing each result of change in power cost and discount rate, as discount rate is weigher than power cost, which means most influential variable of power plan is discount rate one of exogenous variables not endogenous.

As materials cure, the internal electrical flow changes, leading to variations in the dielectric constant over time. This study aims to assess the impact of voltage values extracted from time domain reflectometry (TDR) waveforms, measured during the curing of materials, on predicting the dielectric constant. The experiments are conducted over a curing period ranging from 60 to 8640 minutes, with 30 TDR trials. From the measured waveforms, values of V₀, V₁, V₂, V_f, and Δt are deduced. Additionally, curing time is included as an input variable. Groups A and B are distinguished based on the presence or absence of Δt, indicating a physical relationship between Δt and the dielectric constant. The dielectric constant is set as the output variable. The SHapley Additive exPlanations (SHAP) algorithm is applied to the compiled data. The results indicate that Δt and V₁ are the most influential input variables in both Group-A and Group-B. The study also presents the distribution of SHAP values and interacts SHAP values to infer the interrelationships among the input variables. To validate the reliability of these findings, the partial dependence (PD) algorithm is applied to estimate the marginal effects of each input variable, with outcomes closely aligning with those of the SHAP algorithm. This research suggests that understanding the contributions and proportional relationships of each input variable can aid in interpreting the relationships among various material properties.

With the rapid development of the distributed strain sensing (DSS) technology, the strain becomes an alternative monitoring parameter to analyze slope stability conditions. Previous studies reveal that the horizontal strain measurements can be used to evaluate the deformation pattern and failure mechanism of soil slopes, but they fail to consider various influential factors. Regarding the horizontal strain as a key parameter, this study aims to investigate the stability condition of a locally loaded slope by adopting the variable-controlling method and conducting a strength reduction finite element analysis. The strain distributions and factors of safety in different conditions, such as slope ratio, soil strength parameters and loading locations, are investigated. The results demonstrate that the soil strain distribution is closely related to the slope stability condition. As the slope ratio increases, more tensile strains accumulate in the slope mass under surcharge loading. The cohesion and the friction angle of soil have exponential relationships with the strain parameters. They also display close relationships with the factors of safety. With an increasing distance from the slope edge to the loading position, the transition from slope instability to ultimate bearing capacity failure can be illustrated from the strain perspective.

Brand Relationship Quality(BRQ) reflects the intensity and viability of the enduring association between a consumer and a brand so it is assumed to be the indicator which can affect brand performance such as brand satisfaction, brand attitude, and brand loyalty. The purpose of this study is to analyze the structural equation model showing the path between BRQ and brand performance. The subjects were women in their 20s to 40s living in Seoul and other metropolitan areas. 482 copies of questionnaire were analyzed by reliability, Pearson's correlation analysis, confirmatory factor analysis using SPSS 11.0 Package and AMOS 5.0 Package. The results showed that BRQ had positive influence on the brand performance-brand satisfaction, brand attitude, brand loyalty. As for the total effect about brand loyalty, BRQ was the most influential variable compared with other variables- brand satisfaction, brand attitude. The indirect impact of BRQ on brand loyalty is bigger than the direct impact of BRQ and brand satisfaction emerged as the important intermediate variable between BRQ and brand loyalty. Therefore, effective marketing strategy can be accomplished according to differential impact of the BRQ facets to induce consumer's satisfaction, which can lead to brand loyalty.

The purpose of this study is to identify the influences of parental attitude, parenting attitudes, family function and peer attachment on the self-efficacy of middle school students in multicultural families. In particular, peer attachment was used as a mediator to determine the effects of self-efficacy. 302 multicultural family adolescents who enrolled in Seoul and Gyeonggi-do middle schools were surveyed. In order to measure the variables, this study used such scales as parenting attitude scale, family function scale, peer attachment scale and self efficacy scale. The results were analyzed by the PASW 18.0 program. The findings of the study led to the following conclusions; First, it has shown that peer attachment was the only variable that had significant differences by sex in middle school students of multicultural families. Second, the most influential variables of self-efficacy of middle school students in multicultural families was peer attachment among parenting attitude, family function and peer attachment. Third, there was a mediating effect of peer attachment among parenting attitude, family function and self-efficacy for adolescents of multicultural families. The notable distinction of this study was to find that peer attachment variable is the most important factor of self-efficacy. Considering the results in this study, aggressive intervention is necessary in order to improve the self-efficacy of middle school students in multicultural families.
