Data mining technique is used to find hidden knowledge by massive data, unexpectedly pattern, relation to new rule. The methods of data mining are decision tree, association rules, clustering, neural network and so on. Clustering is the process of grouping the data into clusters so that objects within a cluster have high similarity in comparison to one another. It has been widely used in many applications, such that pattern analysis or recognition, data analysis, image processing, market research on off-line or on-line and so on. We analyze Gyeongnam social indicator survey data by 2001 using twostep clustering technique for environment information. The twostep clustering is classified as a partitional clustering method. We can apply these twostep clustering outputs to environmental preservation and improvement.

There were numerous evidences that subjective health evaluation was a powerful indicator for morbidity and mortality in many countries. Since self-rated health (SRH) was a reasonable health measure, identifying predictors for SRH would be beneficial for assessment of overall health, monitoring health status, and development of health promotion programs. Health risks, health behavior, socioeconomic characteristics and social capital were potential indicators for SRH. We examined association. between SRH and indicators such as health risk factors, subjective living condition, income, education level and dietary variety score. Total 4,262 subjects, aged between 20 and 69 years old, were selected from KNHANES 2001; those who completed health examination, nutrition survey, and provided their socioeconomic information. Results of logistic regression showed that it was likely to have better SRH for those who were younger, male and have higher education, higher income, better living condition, no metabolic syndrome and higher dietary variety.

This study provides a physical indicator of landscape that can be guidelines so as to evaluate landscape agricultural region for visual landscape planning, finds out the guideline for visual landscape planning lastly through examining importance of indicators and the preference of each indicator of landscape. The physical landscape indicators were derived from document study and questionnaire survey to evaluate visual landscape on landscape agricultural region. In addition, field study was conducted to examine and inspect the physical landscape indicator, managers' interview and photograph was took for evaluating the landscape simulation. Moreover, the important elements for visual landscape planning of landscape agricultural region, the importance of physical landscape indicator and the preferences of each indicator were derived by conducting questionnaire to experts and general publics. The physical landscape indicator guideline was established from the following procedures. In case of the land, flat area had higher preference than steep region. So, planning an agricultural area at a flat region with open space will be better than establishing an agricultural area on a steep region. In case of the kind of landscape crops, For the background of landscape agricultural region, the seashore type had the highest preference and mountain type and non-background type was followed in order. According to the study, facilities built with natural elements such as straw-roofed pavilion received high preference. Therefore, look-out shed and straw-roofed pavilion should be introduced in the landscape agriculture planning to select materials and colors to keep harmony with the nature. The result of this study could be used as a best choice for improving visual landscape of landscape agricultural region on selecting suitable land, facilities and so on. Moreover, the results of manager interview could be used as a useful tool in the management and formation of visual landscape. The landscape point evaluating visual landscape of landscape agricultural region could be used as a reference for establishing relative guideline for the direct payment program for rural landscape conservation and landscape agreement. In addition, it could be a useful reference to improve the general landscape and revitalize the rural area.

Objectives: To study the change of personality types of Korean medical students focusing on the Myers-Briggs Type Indicator. Methods: A survey was conducted on 84 Korean medical students to investigate the change of personality types focusing on the Myers-Briggs Type Indicator. Results: In both freshman and senior student groups, the ISTJ was the most common type. The order of the number of the type changes during the university years was 1 type (45.2%)>2 types (23.8%)>3 types (14.3%)>0 types (11.9%)>4 types (1.8%), and the score of I, S, T, P type increased. Conclusions: As a result of the Korean medical students' MBTI type changes during the university years, the types were changed rather than fixed.

The aim of this study is to develop suitability site indicator of urban-rural return to fishing and to analysis priority of the indicators. The study is based on literature review, expert survey and AHP(Analytic Hierarchy Process) methods. This study found 5 factors(natural environment, acceptance environment, social overhead capital, economy, fishing environment) and 21 detail variables. as a result of AHP, fisheries resources, acquisition convenience of fishing license, income(except fishing), attitude of local resident, one-person household income, high income fishing were showed high priority. This result indicate that economic foundation is most important factor for suitable site of the returning.

밤 재배 경영주가 스스로 현재의 경영 상태를 체크하여 어느 정도 수준에 위치해 있는지 파악하고 현재보다 상위의 목표를 설정하여 발전해 나갈 수 있도록 밤나무 경영 표준진단표를 개발하여 활용하고자 하였다. 표준진단표의 작성을 위해 밤 관련 연구자와 밤 주산단지의 선도농가를 전문가로 선정하여 2번의 자문회의를 거쳤으며, 밤 재배 경영기반, 경영 및 판매능력, 생산기술수준으로 구성되는 3개의 대분류 항목과 19개의 중분류 항목을 선정하였다. 작성된 표준진단표를 활용하여 대표적인 밤 주산단지인 청양, 공주, 부여, 순천의 4개 지역에서 총 212개 밤 재배 임가의 경영실태를 설문조사 하였고, 이 중 총 159개 임가의 설문지를 결과 분석에 사용하였다. 표준진단표의 총점은 각 평가 인자 항목의 점수를 합계하여 산출하였는데 전체 임가의 평균 점수는 68.0점으로 나타났다. 지역별로는 부여지역이 69.7점으로 가장 높았고, 순천지역이 61.8점으로 가장 낮게 나타났다. 총점이 높은 그룹일수록 ha당 생산량은 많아지는 것으로 나타났지만, 전체 생산량 중 특품 이상 비율이 증가하는 것과는 통계적으로 연관성이 없었다. 밤재배 경영기반과 경영 및 판매능력에서는 고령의 재배자가 많은 순천지역에서의 점수가 낮은 것으로 조사되었다. 생산기술수준에 대해 살펴보면 4개 지역 모두 70% 이상이 친환경재배를 하고 있어 병해충 방제시 항공 방제를 이용하고 있는 임가는 많지 않은 것으로 나타났다.

An indicator system is an effective way to monitor ongoing safety status. Current aviation safety measurements account for many qualitative technical and lagging indicators. Conversely, quantitative and leading indicators have only a tiny proportion. This research added more quantitative leading indicators and reviewed them to harmonize lagging and leading indicators to measure airport safety and provide an index. The South Korean national gate, Incheon International Airport's indicators, were applied as primary data to verify this research practically. Then, examples from International and national authorities were reviewed and extracted for use. Fifty-five safety specialists participated in the focus group discussion and three rounds of the Delphi survey. Finally, 51 sub-indicators were newly chosen. After this process, weights for each indicator could be assigned using the AHP (Analytical Hierarchy Process) to provide an integrated index. The result of the simulation with newly added indicators in the past five years (2020-2022) reliable trend showed in indicators and integrated index. Moreover, this allows monitoring the status of the details of indicators and holistic insight. This study considered that it is more suitable for a single company or service provider to use it according to the exact situation than in a macro- and general-purpose at the country or regional level.

Clustering is the process of grouping the data into clusters so that objects within a cluster have high similarity in comparison to one another. In this paper we used k-means clustering of several clustering techniques. The k-means Clustering Is classified as a partitional clustering method. We analyze 2002 Gyeongnam social indicator survey data using k-means clustering techniques for environmental information. We can use these outputs given by k-means clustering for environmental preservation and environmental improvement.
