Recently the medical field to efficiently process the vast amounts of information to decision trees, neural networks, Bayesian Networks, including the application method of various data mining techniques are investigated. In addition, the basic personal information or patient history, family history, in addition to information such as MRI, HRCT images and additional information to collect and leverage in the diagnosis of disease, improved diagnostic accuracy is to promote a common status. But in real world situations that affect the results much because of the variable exists for a particular data mining techniques to obtain information through the enemy can be seen fairly limited. Medical images were taken as well as a minor can not give a positive impact on the diagnosis, but the proportion increased subjective judgments by the automated system is to deal with difficult issues. As a result of a complex reality, the situation is more advantageous to deal with the relative probability of the multivariate model based on Bayesian network, or TAN in the K2 search algorithm improves due to expansion model has been proposed. At this point, depending on the type of search algorithm applied significantly influenced the performance characteristics of the extended Bayesian network, the performance and suitability of each technique for evaluation of the facts is required. In this paper, we extend the Bayesian network for diagnosis of diseases using the same data were carried out, K2, TAN and changes in search algorithms such as classification accuracy was measured. In the 10-fold cross-validation experiment was performed to compare the performance evaluation based on the analysis and the onset of high-risk classification for patients with HRCT images could be possible to identify high-risk data.

The purpose of this study was to examine influential factors for the transition to college life and career identity of nursing students and what changes social support from parents brought about to them by academic year. The subjects in this study were 542 selected students who majored in nursing in four-year universities located in Seoul and the provinces. A self-administered survey was conducted to find out their general characteristics, social support from fathers and mothers, college adjustment and career identity. A hierarchical regression analysis was made to determine how social support from parents affected the college adjustment and career identity of the nursing students. Social support from parents had an impact on their college adjustment and career identity. The factors that affected college adjustment were academic year, satisfaction level with major and emotional support from mothers, and the factors that impacted on career identity were academic year, satisfaction level with major and informative support from fathers. In order to facilitate the college adjustment of nursing students, professors should try to develop efficient learning methods, meet with parents to inform them of the necessity of social support, share information on the major field of study and learning methods, and provide an opportunity for students to communicate with graduates or students who are years ahead of them in college so that they could have a better understanding of majoring in nursing.

The purpose of this study is to determine the inhibiting factors of dying well for people who want to have a good death. The final respondents in this study were sampled using stratified proportional allocation using a stratified random sampling method, and 1,000 adults aged between 19 and 75 years were selected. The questionnaire used consisted of four items on general characteristics and 20 items related to the inhibiting factors of dying well scored on a 7-point Likert scale. Analysis was conducted using descriptive statistics, correlation analysis, and decision tree analysis. Results showed that, among the inhibiting factors of dying well, "degenerative diseases (such as dementia)" and "loss of control (mental / physical)" scored 5.502 and 5.268 points, respectively; the highest significant positive correlation was found between "bad marital relationship" and "bad relationship with children," followed by "did not receive death education" and "lack of medical policy promotion (dying well)" and "bad relationship with children" and "indifference of others." Considering these findings, it appears that the whole society will make efforts to improve the perception and practice of good death, and life and death education will be expanded if death education for dying well is organized and implemented.

In this paper, we analyzed the factors influencing the size of Korea Polytechnic as a public vocational education and training institution through analysis of demand, region, industry, and demand with established existing campus and new campus in Korea Polytechnic. By analyzing data on admission, training, and employment for 3 years out of 37 campuses, we have sampled 5 campuses by type of Korea Polytechnic, fused with the results derived from the literature analysis and in-depth analysis results, so that the regional campus will play a leading role and the direction of development. The selection of five campuses by type is a precedent study to analyze 37 campuses in the future. As a result of the study, the demand analysis through objective indicators such as the number of high school graduates, the number of employed persons, the presence of nearby industrial complexes, and policy variables is very important and reflects the reality well. Therefore, it is necessary to analyze the demand through the objective indicators in decision making related to the new campus at the pre-analysis stage. In addition to the general data proposed in this paper, that is, common variables in all regions, it is important to consider the factors that can reflect local demand characteristics when considering specific locations.

The high-tech industry, a leader in the national economy, has a larger investment cost compared to general buildings, a shorter construction period, and requires continuous investment. Therefore, accurate construction cost prediction and quick decision-making are important factors for efficient cost and process management. Overseas, the construction information classification system has been standardized since 1980 and has been continuously developed, improving construction productivity by systematically collecting and utilizing project life cycle information. At domestic construction sites, attempts have been made to standardize the classification system of construction information, but it is difficult to achieve continuous standardization and systematization due to the absence of a standardization body and differences in cost and process management methods for each construction company. Particular, in the case of the high-tech industry, the standardization and systematization level of the construction information classification system for high-tech facility construction is very low due to problems such as large scale, numerous types of work, complex construction and security. Therefore, the purpose of this study is to construct a construction information classification system suitable for high-tech facility construction through collection, classification, and analysis of related project data constructed in Korea. Based on the WBS (Work Breakdown Structure) and CBS (Cost Breakdown Structure) classified and analyzed through this study, a code system through hierarchical classification was proposed, and the cost model of buildings by linking WBS and CBS was three-dimensionalized and the utilized method was presented. Through this, an information classification system based on inter-relationships can be developed beyond the one-way tree structure, which is a general construction information classification system, and effects such as shortening of construction period and cost reduction will be maximized.
