우리나라 대다수 조사전문기관은 지역 성 나이대 할당표본추출에 의한 전화조사를 하고 있다. 그러나 평일에는 인구사회적 속성에 따른 개인별 재택률의 차이가 심하므로 체계적 응답자선택편향(respondent selection bias)이 우려된다. 문제 해결을 위해 조사시간대를 할당변수로 추가한 '시간균형할당표본추출'(time-balanced quota sampling) 방법과 저녁시간대 할당을 부분적으로 완화한 '시간균형준할당표본추출'(time-balanced quasi-quota sampling) 방법을 제안한다. 그리고 우리나라 통계청에서 2004년에 수집한 생활시간조사 원자료를 가상적 모집단으로 설정하여 새로운 할당추출법과 기존할당추출법에 의해 얻는 몬테칼로 표본들을 비교할 것이다.

Relative importance of maritime transport that takes charge of main current of freight in country' economy is very large. Especially, port and facility carry out important role which treats freight of import and export smoothly and improves international trade as turning point, to achieve key role on connection and association between sea and land. For such reason, enlargement of port facilities or development of port needs to grasp exactly the utilization of port, attributes and selective factors of shipper. On the other hand, the amounts of physical distribution on Mokpo port located in Korean west coast are increasing, with fast economic growth of East Asian including China. This study uses discrete choice model that is measuring to analyze attribute and characteristic of Mokpo port, and analyzes port selection by decision factors of shipper. This paper composed a questionnaire using the result of preceding research, to decide port selection factor among competitive ports. Through factor analysis on a basis of the questionnaire' result, five principal components were extracted. These are resorted out by Logit model, to grasp competitive elements of port. This research fin present direction which raises competitive power of ports in west coast of Korea, especially on alternative and concentration of middle-class port as Mokpo may be useful.

The purpose of this study is to analyze the factors influencing consumers purchasing of domestic, imported and craft beer through AHP analysis and to provide implications for marketing for each beer market. In this study, theories and calculations related to AHP analysis were thoroughly examined and selection attributes were determined by referring to existing theories. A total of 164 consumers who have purchased beer were the target of the survey. The results were analyzed by AHP analysis and the differences were analyzed. It was confirmed that the domestic, imported, and craft beer had the highest weight in the taste in the first layer. At this time, we can confirm that imported, and craft beer has a relatively high weight on taste and domestic beer has a relatively high weight on brand image. We also found that design and advertising images do not have a significant impact on beer selection. Even though it is study on beer, we can find people have different preference between their orgin. In this study, it is possible to show what type of factors does the beer manufacturing and distribution company should concentrate on by analyzing factors that consumers consider, unlike other studies focusing on consumption status of existing beer.

This article performs a detailed data scrutiny on a chronic kidney disease (CKD) dataset to select efficient instances and relevant features. Data relevancy is investigated using feature extraction, hybrid outlier detection, and handling of missing values. Data instances that do not influence the target are removed using data envelopment analysis to enable reduction of rows. Column reduction is achieved by ranking the attributes through feature selection methodologies, namely, extra-trees classifier, recursive feature elimination, chi-squared test, analysis of variance, and mutual information. These methodologies are ranked via Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) using weight optimization to identify the optimal features for model building from the CKD dataset to facilitate better prediction while diagnosing the severity of the disease. An efficient hybrid ensemble and novel similarity-based classifiers are built using the pruned dataset, and the results are thereafter compared with random forest, AdaBoost, naive Bayes, k-nearest neighbors, and support vector machines. The hybrid ensemble classifier yields a better prediction accuracy of 98.31% for the features selected by extra tree classifier (ETC), which is ranked as the best by TOPSIS.

Advances in healthcare technology and rapid economic growth lead to the increased life expectancy and consequently the size of elderly population. Korea is one of the countries that are rapidly aging. Thus, it is particularly important to prepare for the aging society. Recently, the number of healthcare institutions for the elderly citizens has increased. The purpose of selecting a hospital for the elderly is, in general, maintenance of health rather than improvement of health receiving proper treatment. Unlike choosing a hospital for treatment, customers of a long term care hospital have a different set of factors to consider. Especially, when choosing a long term care hospital, the influence of patient's family is greater than the patient. This study examines the factors they consider for long term care hospital. A total of 198 questionnaires were collected from the families of actual patients of long term care hospitals. Twelve questionnaires were found to be non-usable because of missing and unsatisfactory responses. Consequently, 186 questionnaires were used for the analyses. Findings of this study are as follows. First, seven factors have been identified to consider when choosing a long term care hospital for the elderly. They include convenience of facilities, costs variety of facility programs, service hours, reputation, accessibility, quality of medical staff, medical facilities, and facility size. Second, This study measured both importance and satisfaction with these attributes and analyzed the difference between them. Satisfaction was lower than importance in the categories of convenience of facilities, costs, and programs, and accessibility. On the other hand, satisfaction was higher in terms of service hours, reputation, and quality of medical staff. Finally, the current study found positive impact of accessibility and quality of medical staff on reuse intention of a long term care hospital.

This study conducted to find influences of selection attributes on consumer satisfaction as perceived by low-cost restaurant visiter by considering personal value. Developed survey was distributed and 428 sample who visited the low-cost franchise restaurant were employed the statistical analyze. The internal value and the external value included individual value in order to estimate the influence of the choice factor of the low-cost franchise restaurant on the quality of the product, and the choice factors were consisted of 3 variables that are quality, accessibility and service. Regression analysis was conducted to verify the relationships among the variables. As a result, the internal value (${\beta}=.236$, p<.0.01), and external value (${\beta}=.352$, p<.001) have the significant positive relationships with respect to quality. Second, the external value (${\beta}=.305$, p<.001) has the positive relationship with regard to accessibility, but the internal value has no significant relationships with level of accessibility. Third, the internal value (${\beta}=.828$, p<.001) has the significant positive relationship with regard to service, but there was no significant influences between external value and service in this study. Fourth, the internal value (${\beta}=.472$, p<.001), the external value (${\beta}=.479$, p<.001) were critical antecedents of the quality. Last, while quality (${\beta}=.858$, p<.001) has significant positive relationship with satisfaction, but it didn't show any relationships with accessibility and service.
