  • In this study, the evaluation items related to the effectiveness evaluation of the LVC (Live, Virtual, Constructive) training system of the Air Force were derived and the weights of each item were analyzed. The LVC training system evaluation items for AHP (Analytic Hierarchy Process) analysis were divided into three layers, and according to the level, 3 items were derived at level 1, 11 items at level 2, and 33 items at level 3. For weight analysis of evaluation items, an AHP-based pairwise comparison questionnaire was conducted for Air Force experts related to the LVC training system. As a result of the survey, related items such as (1) Achievement of education and training goals (53.8%), (1.2) Large-scale mission and operational performance (25.5%), and (1.2.1) Teamwork among training participants (19.4%) was highly rated. Also, it was confirmed that the weights of evaluation items were not different for each expert group, that is, the priority for importance was evaluated in the same order between the policy department and the working department. Through these analysis results, it will be possible to use them as evaluation criteria for new LVC-related projects of the Air Force and selection of introduction systems.

  • Women's menopause is a natural process that every woman must eventually experience, but changes in hormones before and after menopause can serve to produce life-threatening crises in some situations, with individual differences. Data for the study was elicited from 22,610 Korean women ranging in age from 45 to 55 years in the 2013 Korean Community Health Survey. Statistical analyses was performed using descriptive, t-test, ANOVA, and hierarchical regression analysis using SPSS IBM 20.0 version. Individual characteristics, lifestyle, history of chronic disease(s), psychological and environmental factors were included as independent and EQ5D weights of Koreans were used as dependent variables. The survey subjects consisted of a total 15,505(58.3%) in their 50s, 1,765 (66.5%) in middle and high school dropouts or graduates, 22,174 (83.3%) living in spouses and 10,534(39.6%) in wages. There was a significant difference in HRQOL among all independent variables except drinking and residential areas. Hierarchical regression analysis showed that age, smoking, obesity and other incidental disease factors (fall, angina, asthma, arthritis, osteoporosis, stroke) had a negative effect on HRQOL. The selected independent variables accounted for 22.7% of HRQOL. It is necessary to find a way to improve HRQOL of Korean perimenopausal women, focusing on the significant variables revealed by the study results.

  • Korea Health Panel Survey (KHPS) has been conducted to provide nationally representative estimates of health care use and expenditures for non-institutionalized population in Korea since 2008. The aim of this study was to present estimates from KHPS on dental utilization and expenditures from 2008 to 2011. While weighted estimates were presented for each year from 2008 to 2011, the focus of this study was on the 2011 estimates and changes in dental utilization and expenditures between 2008 and 2011. Weighted estimates were obtained using population weights and statistical significances were analysed by independent t-test or ANOVA test using SPSS version 20 for Windows. In 2011, 21.1% of Korean population obtained outpatient dental services from dentists. From 2008 to 2011, the percent of people with a dental visit in each year increased slightly. In 2011, the mean number of dental visits was 4.46. While the mean number of dental visits remained stable by 2010, it increased slightly in 2011. The total annual dental expense in 2011 for people with a visit was about 460,000 Korean Won and 10% higher in 2008. In summary, this study results highlight low rates of dental utilization and high dental expenses in Korean population.

  • Background: The purpose of this study is to identify the factors affecting the depressive mood experience in university students by gender. Methods: This study is a descriptive survey that conducted a secondary analysis using data from the 2020 Community Health Survey, which is conducted annually in Korea. The study targets 8,928 college students, 4,682 male students and 4,246 female students. Data analysis was conducted after creating a composite sample plan file that reflected layering variables, colony variables, and weights. Results: Factors affecting the depressive mood experience of both males and females were household income, smoking, subjective stress levels, changes in drinking and smoking, and the number of encounters caused by coronavirus disease 2019 (COVID-19). Factors influencing the depressive mood experience of females were the presence of breakfast, changes in physical activity due to COVID-19, and the presence of helpers in self-quarantine due to COVID-19 (p<0.05). Conclusion: Psychological counseling programs should be promoted to actively utilize mental health in those in their 20s and 30s. Universities also need to detect depressed students early through screening and perform timely and appropriate interventions.

  • Objectives : To measure DALE (Disability-Adjusted Life Expectancy) in Korea to find out how long Koreans live in a state of full heath. Methods : DALE was calculated using the life table of 1999 and the disability prevalence from the National Health Interview Survey (NHIS), which was conducted with a sample of 13,523 households in 1998. The disability prevalence was measured using the annual prevalence of the long-term limitation of activities, which were divided into classes 1, 2, 3, 4, 5 and 6 according to the severity of the limitation. The disability weights were measured for each 6 class by conducting a survey of 16 healthcare professionals. The severity-adjusted disability prevalence was calculated by multiplying the disability prevalence of each class by the disability weights respectively. Healthy life years lost due to disability was calculated by multiplying the life expectancy by the severity-adjusted disability prevalence. Finally DALE was measured as the life expectancy minus healthy life years lost due to disability. Results : DALE for 1999, which refers to the expectation of equivalent years of good health, were 72.5, 69.5 and 75.3 years, for total, for males and for females, respectively. The percentages for DALE out of the life expectancy were 95.8, 96.6 and 94.4% for total, for males and for females, respectively. Conclusions : DALE is a newly developed indicator, which could effectively show the healthy life expectancy of populations. A greater notice and use of DALE would be expected as life expectancies increase and the quality of life changes in Korea.

  • 지역교육청 수요자 만족도조사를 위한 표본설계는 경상남도의 2009년 경남지역교육청 고객만족도 조사의 표본크기에 기초하여 시 군별 지역교육청평가에 맞추어 설계하였다. 대도시의 구단위 지역 교육청과 달리 지방의 시 군 교육청은 학생수와 학교수, 학급당 학생수 등의 변동이 크다. 시간 비용 등을 고려하여 전체 표본크기를 작게 하면서도 각 시 군 교육청 평가에 필요한 최소표본수를 확보하도록 설계하였다. 경상남도는 10개의 시지역과 10개의 군지역을 가지고 있고, 학생수가 상대적으로 작은 군지역교육청 평가에 필요한 최소표본수를 확보하기위해 지역별 평가에 필요한 최소표본을 우선배분한 후, 나머지는 지역별 학급수에 비례배분하였고, 표본학교는 지역과 학교설립유형별로 층화하여 학급수에 비례하여 추출하였다. 표본학교 내에서 조사대상 학생은 2단집락추출하였다. 지역별 추출율의 상이함을 보정하기 위해 가중치를 산정하였다. 조사자료의 분석은 가중치를 적용하여 가중평균, 가중총합 등을 이용하며, 분산의 추정은 통계소프트웨어에서 제공하는 균형반복복제, 잭나이프, 선형화방법 등을 사용할 수 있다.

  • 본 논문에서는 원전해체 시 적용 가능한 제염기술을 조사하여 분석하였다. 이를 기반으로 최적의 제염기술을 선정하기 위해 의사결정 기법(EXPERT-CHOICE)을 사용하여 기술성을 평가하였다. 이 평가방법은 해당 분야의 전문가로 이루어진 전문가 집단에 의해 수행되는 것이 일반적이다. 가중치를 고려한 결과는 각 기준에 대한 가중치에 평가점수를 곱한 총합을 구하는 식으로 수행하였다. 평가 점수를 3단계로 하여 High, Medium, Low로 구분한 후 가중치를 부여하여 차별화 시킬 수 있다. 하위분류 기준의 세분화와 각 기준 별 가중치의 추가 정량화를 통하여 기술성 분석의 수준을 제고할 수 있고, 좀 더 설득력 있는 결과의 도출을 예상할 수 있다. 평가의 기본 가정은 각 기준 별 가중치를 전문가 조사에 의해 부여하며, 평가 기준은 High에 좀 더 비중을 주는 식으로 차별화 하였다. 이를 반영하면 H, M, L는 대략 "10:5:1"의 비율로 평가 점수를 부여받는데, 이는 EXPERT-CHOICE 기법의 최적화 분석에 따른 것이다. 최고 및 최저값을 제외한 나머지 결과값의 평균을 평가치로 고려하였다.
