이 연구에서는 예비 교사들이 갖고 있는 TPACK의 실천적 역량을 측정하기 위하여 기존의 연구들에서 사용한 TPACK 측정 설문지와 수행평가를 통해 드러난 TPACK 역량의 관계를 비교하였다. 이를 위하여 이 연구에서는 예비 교사의 TPACK 설문지를 개발하였다. 또한 '달과 천체의 변화'에 관련된 수행평가 과제 및 면담을 통해 예비 교사의 TPACK 역량의 실제를 분석하였다. 설문 분석 결과에서는 예비교사들의 PCK와 TPK이 높게 나타났고, 상대적으로 TCK와 TPACK이 낮은 것으로 나타났다. 그러나 설문에서는 TPK가 낮은 것으로 나타난 예비교사의 수행평가를 분석한 결과 TPK가 높은 것으로 나타났다. 반대로 설문에서는 TPK가 높은 것으로 나타난 예비교사의 수행평가를 분석한 결과 TPK는 낮은 것으로 나타났다. 또한 설문에서 TCK가 낮은 것으로 나타난 예비교사의 수행평가를 분석한 결과, 반대로 TCK가 매우 높은 것으로 나타났다. 반대로 설문에서 TCK가 높은 것으로 나타난 예비교사의 수행평가를 분석한 결과, 실제 TCK 역량은 낮은 것으로 나타났다. TPACK가 설문에서는 높게 나타난 경우에도 수행평가의 실제 결과를 통해서는 TPACK가 낮은 것으로 나타났다. 이를 통해 TPACK 측정 도구들이 실행 역량 보다는 자기효능감을 측정하는 것임을 확인하였다.

The purpose of this study was to investigate the effects of Engel coefficient, Angel coefficient and Schwabe index influencing Household head's life satisfaction. For this study, the data from the 8th analysis of the 2013 Korea Welfare Panel Survey conducted by Korea Institute for Health and Social Affairs were used. For the sample, 903 male Household heads with children under the age of 18, were selected. For statistical analysis, SPSS program (Ver. 21.0) was used. And for statistical methods, frequency and percentile, mean and standard deviation, Pearson's correlation, one way analysis of variance, Duncan's multiple range tests, multiple regression analysis were used. The findings are as follows. First, as a results of analyzing the food costs, education costs and housing costs depending on Income Quintile, the food costs and education costs in the 5th Income Quintile compared with other Income Quintile, were highest. Also, the highest housing cost was in the 2nd Income Quintile, while the least housing cost was in the 1st Income Quintile. Second, by analyzing the differences of Engel coefficient, Angel coefficient and Schwabe index according to Income Quintile, the results show that Engel coefficient and Schwabe index decreases as Income Quintile increases, and Angel coefficient increases as Income Quintile becomes higher. Third, the level of HH's life satisfaction according to Income Quintile, 1st Income Quintile, 2nd Income Quintile, 4th Income Quintile, 3rd Income Quintile, 5th Income Quintile in order, increased. Fourth, as the result of analyzing the influence of Variables related to household and demographics about Engel coefficient, Angel coefficient and Schwabe index, it was shown that the variables effecting Engel coefficient, Angel coefficient, and Schwabe index are age, occupations, Number of workers, House ownership, Income Quintile. Fifth, As a result of analyzing the Variables effecting life satisfaction, especially while Schwabe index is not that significant, Engel coefficient and Angel coefficient are shown to have a significant influence. Therefore, the influence of Food costs and education costs can be confirmed.

While the use of radiation in the medical field provides diagnosis and treatment with important benefits, we cannot deny that the radiation bombing causes some hindrances. The expansion of radiation use in modem medicine is essential, so the radiation use and preparation of proper measure for safety management has risen as a pressing subject. Therefore, in order to make defensive plans for the prevention of health obstacles to general users of radiation and for the provision of basic data of the health education programs to radiation workers by grasping the knowledge, attitude and behavior towards the radiation safety management of radiation workers in each medical institution and by analyzing the factors that affect the actions of radiation safety management, in this study we conducted questionnaires from September 26 to November 5, 2001 targeting 805 radiation workers in 108 medical institutions including university hospitals, general hospitals, hospitals, clinics and public health centers etc. located in Seoul, four metropolitan cities and small and medium cities, and has obtained the following results. 1. The average point of knowledge on the radiation safety management was 10.96 out of 15. As for the general characteristics, the level of knowledge on radiation safety management was higher with older age, high education background and longer career. 2. The average point of attitude on the radiation safety management was 66.36 out of 75. The attitude point for general characteristics were higher with higher education background, longer career and in case of universities, the level of attitude on the radiation safety management was high. 3. The average of action points on the radiation safety management was 56.09 out of 75. In general characteristics, the action level of radiation safety level was higher with older age, longer career, and the reception of radiation education and in case of university hospitals. 4. It is analyzed that the relation of knowledge, attitude and behavior on the radiation safety management is higher as the levels of knowledge and attitude on the radiation safety management is higher. 5. As a result of analyzing the factors that affect the knowledge on the radiation safety management, the variables that can be explained best was in the order of ‘the behavior on the radiation safety management’, ‘work career’, ‘the attitude on the radiation safety management’, and ‘school career’. 6. As a result of analyzing the factors that affect the attitude on the radiation safety management, the variables that can be explained best was in the order of ‘the behavior on the radiation safety management’, ‘the knowledge on the radiation safety management’, and ‘school career’. 7. As a result of analyzing the factors that affect the behavior on the radiation safety management, the variables that can be explained best was in the order of ‘the attitude on the radiation safety management’, ‘the knowledge on the radiation safety management’, and ‘the frequency of radiation education

과거 물리적 공간에서만 수행되던 작전이 사이버 공간을 포함하는 작전으로 바뀌면서 사이버 공격이 사이버 시스템을 활용한 무기체계에 어떤 영향을 미치는지 분석할 필요가 있다. 이를 위해 사이버와 연계한 물리적 무기체계의 영향을 분석하는 도구를 분석하는 것은 의미가 있을 것이다. 한국군은 물리 무기체계의 영향을 분석한 결과가 담긴 미군 JMEM을 확보해 운용하고 있다. JMEM은 재래식 무기체계에만 적용되어 사이버 무기체계의 영향을 분석하는 것은 불가능하다. 이를 위해 물리전의 MOE와 MOP를 기반으로 사이버 무기체계 효율성 분석을 위한 사이버지수를 산출하였다. 또한, 물리 작전에서 무기체계 효과 매뉴얼로 활용되고 있는 JMEM과 연계하여 사이버 공간에서의 전투 결과와 물리 작전의 효과를 비교 분석하여 임무 영향을 판단할 수 있는 프레임워크를 설계 및 시험하였다. 제안된 프레임워크를 입증하기 위해 국내외 군사 매뉴얼과 선행연구를 통해 작전 시나리오를 분석 및 설계하고 자산을 정의하고 실험을 수행하였다. 실험 결과 사이버 임무 효과 값의 감소가 클수록 물리적 작전에 미치는 영향이 커졌다. 다양한 작전에서 사이버 공격으로 인한 물리적 작전의 영향을 예측하는 데 사용할 수 있으며, 전장의 지휘관이 빠른 결정을 내리는 데 도움이 될 것이다.

Purpose: The size of the salad consumption market has expanded since Covid-19, and continuous growth is predicted. Therefore, by extracting influential core purchasers in the salad consumption market and analyzing their purchasing behaviors and consumer types, this study intended to provide basic data for establishing a marketing strategy. Methods: The analysis data is the purchasing data of 576 people who have purchased salads between 2016 and 2020 (panel data of the Rural Development Administration), and in the social network analysis, the centrality structure was analyzed. Results: First, in the results of analyzing the causes of the rapid increase in salad consumption in 2020, it was found that the increase in consumption of new purchasers (n=102) had little effect. The existing consumer type (n = 474), which has been the majority of the salad consumption market so far, were consumers with stable income. However, the results of study indicated that the type of consumers has expanded since low-income class as well as high-income class increased consumption of purchasing salad. Second, in the results of analyzing the types of key purchasers with great influence in the salad consumption market, there was a difference from the results of frequency analysis in age, number of family members, existence/absence of children, and income decile. This suggests that there should be a difference between the type of customers according to the apparent quantitative figure and the actual influential purchasers. Third, in the results of analyzing the salad purchasing behaviors of core purchasers, the purchasing site for existing purchasers was large-scale marts and for new purchasers it was corporate-type supermarkets. Purchases were concentrated on Saturdays for both existing and new purchasers. As for the purchased products, existing purchasers had a high preference for products made of chicken, and new purchasers had a high preference for vegetable/fruit salad. In particular, in the results of purchased products by age group, in the case of 50s and 60s, it was an interesting result that there was a difference between the products purchased by the existing and new purchasers even though they were the same age. Conclusion: When establishing a marketing strategy in the salad consumption market, it is necessary to pay attention to the purchasing behavior of key buyers.
