The purpose of this study is to develop competitiveness evaluation index for global aviation training organizations. Research and studies on relevant documents were conducted to establish the index. With no sufficient study results previously done directly associated with global aviation training organization, relevant and related documents, such as studies on competitiveness evaluation index of higher educational institutions, were reviewed as an alternative. Two rounds of delphi surveys were conducted based on the review and consultation from experts in aviation training and human resource management fields. First round of survey with 62 evaluation indices were carried out, through which a total of 29 were selected, and 19 indices were chosen during the second round of survey. However, factor analysis was conducted in order to justify the survey result, which eliminated 3 more indices, with 16 finally selected. This study will provide implications for aviation training organizations which need to further improve their competitiveness globally.

An Economic Sentiment Indicator(ESI) is a composite indicator of business survey indices(BSI) and consumer survey indices(CSI). The ESI designed to reflect economic agents' (this includes producers and consumers) overall perceptions of economic activity in a one-dimensional index. The European Commission has published an ESI since 1985. This paper demonstrates the construction of an ESI for the Korean economy. The BSI and CSI components (having a high correlation and a leading feature with respect to GDP) are selected to construct the ESI and they are aggregated using a weighted average and then scaled to have a long-term average of 100 and a standard deviation of 10. Thus values greater than 100 indicate an above-average economic sentiment and vice versa. The newly constructed Korean ESI that extends to January 2003 shows a good tracking performance of GDP and adequately reflects the overall perception of economic activity.

경기상황에 대한 기업과 소비자들의 인식을 효과적으로 파악하기 위해 기업경기실사지수 (BSI)와 소비자동향지수 (CSI)를 편제하고 있는 한국은행은 2012년부터 이 두 지수를 합성한 경제심리지수 (ESI)를 추가로 개발하여 발표하고 있다. ESI는 그 유용성을 인정받고 있으나 지수의 예측력 측면에서 개선의 여지가 있는 것으로 나타났다. 본 연구에서는 ESI에 대해 유용성 평가 작업을 실시하고 그 결과를 토대로 현행 ESI의 편제방식의 개선 또는 보완 방법을 모색하였다. 실증분석 결과 ESI 구성요소의 최적 가중치 탐색과정에서 슬라이딩 윈도우 방법을 이용한 동적 최적 가중치 탐색은 기존 ESI의 구성방식을 보완하거나 또는 경제상황을 고려하여 ESI 구성항목들의 가중치를 부여하고자 할 때 매우 유용한 방법이라고 판단할 수 있었다.

The aim of this study was to explore the relationship between demographic characteristics and atopic dermatitis, along with adolescents' body mass index. Also, this study explored the association between dietary intakes (fruits, soda, caffeinated beverages, instant food, cracker, vegetables, and milk) of adolescents and atopic dermatitis. Korea Youth Risk Behavior Web-based Survey for 2014 was used for data analysis, in which a total of 3,532,149 middle and high school students participated. Data were analyzed by descriptive analysis and logistic regression based on the complex sample design using SPSS ver.20.0 statistics. The results showed that males had a higher prevalence rate of atopic dermatitis than females. The significant association between body mass index and atopic dermatitis was found (F=46.625, P<0.001). Students who have higher levels of body mass index showed a higher prevalence rate of atopic dermatitis. Finally, the findings showed that the intake of vegetable and milk had associations with atopic dermatitis (F=6.795, P<0.001). Greater vegetable intake was associated with less atopic dermatitis whereas greater milk intake was associated with more atopic dermatitis prevalence. Based on the above results, we found that demographic characteristics, body mass index, and some dietary food intakes of adolescents had influences on prevalence rate of atopic dermatitis.

기업경기실사지수는 기업의 지난 실적과 기업가의 계획이나 판단 등을 기초로 하여 만들어지는 대표적인 경기 전망 지수이다. 이 지수는 경제 현장에서 널리 사용됨에도 불구하고 아직까지 규명된 통계적 성질은 많지 않다. 본 논문에서는 기업경기실사지수에 대한 통계적 성질을 고찰한다. 유한모집단에서 모집단 기업경기실사지수를 정의하고 단순확률표집을 가정한 후 모집단 기업경기실사지수 추정량을 구하며, 기업경기실사지수의 기댓값, 분산, 비편향 분산 추정량, 신뢰구간, 상대표준오차를 구한다. 그리고 기업경기실사지수의 평가지표로서 상대표준오차보다는 신뢰구간이 더 합리적임을 언급한다.

Purpose: The purpose of this study is to apply the Bayesian estimation methodology for producing 'Korean Standard -Quality Excellence Index' model and prove the effectiveness of the new approach based on survey data by comparing the current index with the new index produced by Bayesian estimation method. Methods: The 'Korean Standard -Quality Excellence Index' was produced through the collected survey data by Bayesian estimation method and comparing the deviation with two results for confirming the effectiveness of suggested application. Results: The statistical analysis result shows that suggested estimator, that is, empirical Bayes estimator improves the effectiveness of the index with regard to reduce the error under specific loss function, which is suggested for checking the goodness of fit. Conclusion: Considering the Bayesian techniques such as empirical Bayes estimator for producing the quality excellence index reduces the error for estimating the parameter of interest and furthermore various Bayesian perspective approaches seems to be meaningful for producing the corresponding index.

This research This research aims at developing systemic evaluation model in terms of biotope preservation through reports, literatures, and expert survey analysis by implementing biotope structure analysis in area level with selecting Hyunpoong and Yuga-myeon, Dalseong county, Daegu metropolitan city as a site. First of all, as a result of biotope type classification of research site, biotope type groups are classified into total 13, and its biotope types are divided into total 61. Also, as a result of literature analysis, total 18 items are drawn such as diversity of biotope typical species as a index item to assess the preservation value of biotope, and the first evaluation index are divided into 10 and the second ones are divided into 8 according to characteristic of index items. As a result of expert survey analysis, All 10 index items, first evaluation index, show high importance average (above 4.7). As a result of implementation of main cause for categorizing evaluation index by characteristic, there are 3 factors such as 'obstructive factor.' Based on above survey analysis result, as a result of estimating the weight of each item, 'restoration factor' showed the highest, 3.4541, but 'factor of habitat stability' showed 3.1468, which is the lowest The systemic value evaluation was set by comprehensively analyzing these results. As a result of biotope preservation value evaluation through applying research site, total 19 types which are abundant in vegetation are classified into I class, 12 types in II class, 5 types in III class, 10 types in IV class, and 15 types in V class respectively. Lastly, as a result of second evaluation, it is analyzed that there are 17 special meaningful space to preserve species and biotope(1a, 1b) and 61 meaningful space to preserve species (2a, 2b, 2c).

There is a serious risk of regional extinction due to low birth rate and aging in Korea. Accordingly, the regional extinction index is applied to diagnose the extinction status of cities, counties, and districts. However, when the regional extinction index was applied to rural villages, most villages were found to be at 'high risk of extinction'. There is no differentiation in the level of extinction of rural villages. Therefore, a village extinction index was developed to apply to rural villages. This study applies and compares the existing regional extinction index and the newly developed village extinction index to rural villages. The purpose is to propose an index that can better diagnose the extinction of rural villages. As a research method, the regional extinction index and village extinction index are applied to all villages in Haengjeong-ri villages in South Chungcheong Province. And the adequacy of the index suitable for rural villages is diagnosed. For this purpose, ➂ stage distribution for each two indices, ➂ demographic aspect diagnosis, and ➂ resident awareness survey were analyzed. When the village extinction index was used, the discrimination problems seen in the regional extinction index were overcome. As a result of the demographic analysis, the regional extinction index showed that villages with a population of 200 or more were at 'high risk of extinction', but the village extinction index was derived as 'high risk of extinction' for villages with underpopulated populations. Lastly, the results of the residents' awareness survey also showed that the village extinction index was well reflected in the actual situation of rural villages when applied. When the village extinction index was applied to rural villages rather than the regional extinction index, it was found to reflect the actual state of rural extinction better.

Objectives : We supposed that identifying the influencing factors on DMFT index in the primary school children in Pocheon be indispensible for the primary school children's oral health program establishment in Pocheon. So, to prepare the basic materials for the primary school children's oral health program establishment in Pocheon, we analyzed the associated factors which could have an influence on the primary school children's DMFT index in Pocheon. Methods : We selected 3,676 primary school children in Pocheon, whose age were from 6 to 11, and surveyed those children by a questionnaire and the oral examination based on WHO's oral health survey method. Data were analyzed with a $x^2$-test and multiple regression analysis using SPSS $15.0^{(R)}$. Results : The results of oral survey in the primary school children in Pocheon revealed as follows: DMFT index, National Health Oral health survey of 2006 people nationwide in the results when compared to younger grade children and older grade in the low and the higher. Subjective oral health awareness, high of viscosity junk food snacks, fruit, gender, dental visits and humidity, oral health education classes, including the variable of attitude was 6(p<0.05). Their higher awareness of dental health, oral health education classes ever the more positive attitude to DMFT index was statistically significant(p<0.05). Solid in the habit of eating junk food snacks to the students of a liquid relative to student intake was higher DMFT index indices(p<0.05). Conclusions : We could reason that one's oral health recognition and behavior should have a relationship with his(her) DMFT index.
