This study, a sub-one of comprehensive research work titled under "A Evaluation System of Amenity / Disamenity Elements in Rural Villages", tried to propose a rational methodology for development of rating tabulation for evaluation of amenity / disamenity elements in rural villages. The system developed in the study has the formalized rating grades between 2 and 5 for convenience/simplification of analysis work. For each evaluation element in the lowest order of the system, 5 types of rating technique were arranged, which were based on statistical analysis using mean and standard deviation values, its existence or not, relative significance of its holding volume and quality, synthesized weight scale of its quality and quantity, and the others. And, standardized 4-steps procedure for rating tabulation was proposed. Finally, through case studies of 4 sample villages representing the flat-plain, upland, seashore and periurban rural areas, the applicability of this rating tabulation system was verified.

This study, a sub-one of comprehensive research works titled under "Rural Resources Evaluation System", tried to propose a rational methodology for development of rating tabulation on evaluation items. Firstly, the database system for handling of original/processed data of each evaluation items was constructed, being mainly focussed on the possibilities of data acquisition and statistical treatment. The rating tabulation system developed in the study has the formalized evaluation classes as 2 or 5 for convenience/simplification of analysis works. For each evaluation item in lower step of the goal system, 5 types of rating technique were arranged, which were based on statistical analysis using mean and standard deviation values(Type I), its existence or not(Type II), relative significance of its holding volume(Type III), synthesized weighting scale of its quality and quantity(Type IV), and the others(Type V). And, standardized 4-steps procedure for rating tabulation was proposed. Finally, the rating tabulation system developed in the study was applied to each evaluation item of goal system, from which the numerically-valued ranking criteria was obtained.

In this study, factor and cluster analysis have been conducted to group the differences in Korean view on national economic policy in the sample of the 2006 Korean General Social Survey (KGSS). According to the 2006 KGSS, the 6 items with a 5-point Likert scale include the questions about whether or the extent to which each respondent supports the specific types of governmental economic policy. In our study, at first, the factor analysis has converted the original 6 items into the 3 composite variables that account for 81% in the total variability. As the second step of factor analysis, factor scores have been computed. Then, the K-means cluster analysis based on the factor scores has been conducted to group the survey respondents into the 3 clusters. In particular, the cross-tabulation analysis has shown that the distribution of the 3 clusters varies with the respondents' socio-demographic characteristics.

이 연구는 BMI 분류기준과 9점-신체상평정척도 분류기준의 일치도를 조사하여 현장적용의 유용성을 확인하고, 여대생들이 체형에 대해 실제로 인식하고 정도를 파악하여 체형인식의 왜곡에 대한 올바른 정보와 비만의 기준에 대한 정보 제공에 목적이 있다. BMI 분류기준과 신체상평정척도 분류기준의 일치도, 그리고 여대생의 BMI에 따른 신체상 인식 정도를 알아보기 위하여 교차분석, Spearman의 등위차상관계수 및 카파통계량을 산출하였다. 분석결과 일반 여자대학생이 판정한 신체상 평정척도 분류기준과 BMI 분류기준은 통계적으로 ${\rho}=.719$(p<.001)로 높은 상관과 ${\kappa}=.506$(p<.001)로 보통 수준의 일치도를 나타냈다. 이러한 결과를 바탕으로 차후 신체상과 관련하여 인종의 특성에 따른 크기와 형태를 조정할 필요가 있으며 인구통계학적 특성이 다르거나 비만도가 높은 대상자를 선별하여 그들의 체형인식과 심리적인 측면에 관한 추가적인 연구가 필요하다.

Purpose. The purpose of this study was to provide basic data regarding the intention to use community care service based on special grading for dementia in the South Korean Society. Methods. A survey was conducted using a questionnaire adapted on the basis of literature review regarding the first to fourth grade under the long-term care insurance system for the aged from May 1 to 30, 2015 and a total of 272 questionnaires were statistically processed using SPSS 21.0. Frequency analysis, descriptive statistics, and cross-tabulation analysis were performed. The non-parametric type of test, ${\chi}^2$ test, was used for statistical testing. Results. This study obtained the following results: First, caregivers had greater intention to ask recipients to use daytime and nighttime care service. Second, there were statistically significant differences in caregivers' education, occupation, monthly average income, co-residence status, intimacy, and care-giving burden (emotional, financial, and social) and recipients' activities of daily living, instrumental activities of daily living, mental health status, dementia status, and intention to use community care service based on special grading for dementia. Conclusions. There are very few statistical data and academic materials regarding special grading for dementia, which has recently been established. The results of this study are therefore expected to help make a systematic analysis of the intention to use community care service by caregivers based on special grading for dementia.

Objectives: The Korean Ministry of Environment has identified cases of people suspected of suffering lung disease potentially caused by polyhexamethylene guanidine (PHMG) used in humidifier disinfectants (HDs). Exposure assessment for the HDs was conducted using a questionnaire during face-to-face interview. The main purposes of this study were to develop a methodology to effectively classify levels of exposure to HDs based on a questionnaire. Methods: We first identified the overall participants' exposure characteristics by HD exposure levels; Second, we selected misclassified subjects and investigated characteristics of overestimated and underestimated subjects, focusing on exposure cases to PHMG-containing HDs. An inhalation reference concentration (RfC) for PHMG was produced on the basis of inhalation toxicity values. We made a cross-tabulation of the exposure classes (Exposure classes 1-to-4) by clinical classes based on the RfC. When the value of the exposure class minus the clinical class was 0 or 1, we assumed these were true values. When the value was ≥2 and ≤ -2, we assigned these cases to the overestimation group and underestimation group, respectively. Results: The overestimated group may have already recovered and responded excessively due to psychological anxiety or in order to receive compensation. On the other hand, relatively high mortality rates and surrogate responses for those under 10 years of age may have resulted in inaccurate exposure assessment for underestimated groups. For the characteristics of exposure, it was shown that for the underestimated group, the exposure was relatively weaker than the overestimated group, even though a high overall clinical rating was determined. Conclusions: This study may suggest ways to reduce bias and overcome the limitations of current HD exposure assessment.

본 연구의 목적은 신용보증기금으로부터 투자받은 기업의 비재무정보를 활용하여 기업 부실에 영향을 주는 요인들을 검증하는 것이다. 본 연구에서는 2014년 3월부터 2022년 12월말까지 신용보증기금에서 투자받은 594개(정상기업 525개, 부실기업 69개) 기업을 표본으로 선정하였다. 기업의 비재무정보를 창업자 특성정보, 기업 특성정보, 기업 투자정보로 구분하여 교차분석과 로지스틱회귀분석을 실시하였다. 교차분석 결과 개인신용등급, 업종, 공동투자여부가 유의한 변수로 선정되었고, 그 변수들을 대상으로 로지스틱회귀분석을 실시하여 개인신용등급, 공동투자여부 등 2개 변수가 부실의 중요한 요인으로 선택되었다. 기업경영에 있어 창업자의 개인신용과 투자지원시 공동투자의 중요성을 알 수 있었다. 중소벤처기업에 투자를 지원하는 기관이 이러한 결과를 심사에 반영하고, 민간투자기관과의 협력관계를 체계적으로 구축하면 부실을 최소화하는데 도움이 될 것이다. 본 연구를 통해 공공기관의 직접투자를 지원받는 기업의 부실에 영향을 미치는 요인들에 대하여 더욱 관심을 갖는 계기가 마련되길 바란다.
