This paper addresses for the first time the use of complete data information criteria in unsupervised learning of the Naive-Bayes model. A Monte Carlo study sets a large experimental design to assess these criteria, unusual in the Bayesian network literature. The simulation results show that complete data information criteria underperforms the Bayesian information criterion (BIC) for these Bayesian networks.

It is not easy to select a linear mixed model since the main interest for model building could be different and the number of parameters in the model could not be clearly defined. In this paper, performance of conditional Akaike Information Criteria and its bias-corrected version are compared with marginal Bayesian and Akaike Information Criteria through a simulation study. The results from the simulation study indicate that bias-corrected conditional Akaike Information Criteria shows promising performance when candidate models exclude large models containing the true model, but bias-corrected one prefers over-parametrized models more intensively when a set of candidate models increases. Marginal Bayesian and Akaike Information Criteria also have some difficulty to select the true model when the design for random effects is nested.

Recently, to use the evaluated firewall is recognized as a solution to achieve the security and reliability for government and organizarions in Korea. Results of firewall evaluation using ITSEC(Information Technology Security Evaluation Criteria) and CCPP(Common Criteria Protection Peofile)have been announced. Because there are problems to apply ITSECor CCPP for the firewall evaluation in korea environment, korea government and korea Information security Agency (KISA) decided to develop our own security dvaluation critrtia fir firewalls.As a result of the efforts, Korea firewall security evaluation criteria has been published on Feb. 1998. In this paper, we introduce Korea security evaluation criteria for firewalls. The ceiteria consists of functional and assurance requirements that are compatible with CC Evaluation Assurance Levels(EALs)

Effective recommendation of similar business groups is a critical factor in obtaining market information for companies. In this study, we propose a novel method for enhancing similar business group recommendation by incorporating derivative criteria and web crawling. We use employment announcements, employment incentives, and corporate vocational training information to derive additional criteria for similar business group selection. Web crawling is employed to collect data related to the derived criteria from 'credit jobs' and 'worknet' sites. We compare the efficiency of different datasets and machine learning methods, including XGBoost, LGBM, Adaboost, Linear Regression, K-NN, and SVM. The proposed model extracts derivatives that reflect the financial and scale characteristics of the company, which are then incorporated into a new set of recommendation criteria. Similar business groups are selected using a Euclidean distance-based model. Our experimental results show that the proposed method improves the accuracy of similar business group recommendation. Overall, this study demonstrates the potential of incorporating derivative criteria and web crawling to enhance similar business group recommendation and obtain market information more efficiently.

Recently IT industry has its eyes on IT Converged Technology as its future growth engine. Now, local governments are busy with planning U-City Constructions to improve their competitiveness. While this shows the ripple effect of U-City Constructions, the related standards or laws don't still seem to be established. The existing Construction Criteria which comprehends only construction could not apply to U-City development. Therefore Construction-Information Converged Technology Criteria should be needed. And fundamental research of Criteria should be preceded. The objective of this research is to develop Structure of Construction-Information Converged Technology Criteria on U-City. The new comprehensive Criteria for Construction-Information Converged Technology would be fundamentally basic standard for U-city development. Thereafter local governments, the main body of the projects, could use Construction-Information Converged Technology Criteria so that there must be lest trial and error to Construction U-City Project.

Objectives: In this paper, the survey on internet usage patterns of health consumers was conducted and analyzed in order to determine internet health information assessment criteria for providing correct consumer health information on web-sites. Methods: By using a survey questionnaire with 16 questions on general information and 20 questions on internet health information, data were collected from September 16 to 25, 2005 from 476 participants through an internet web site, http://www.hp.go.kr. Frequency analysis, t-test, and multiple regression were used in order to analyze the difference in assessment criteria, factors influencing assessment criteria, factors influencing user satisfaction, etc. Results: General characteristics of the study population were: the persons over age 40 were the smallest age group; women were accounted for 74.2%; and the persons with average income were the largest income group; and the persons with average health status were the largest health group. Most widely used health information were: exercise, disease, and diet, in order. There was significant difference(p=.001) in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. There was no significant difference in other assessment criteria. We also found that contents of websites and easy to use were more important factors than elucidation of information providers and information sources including speciality of information in quality assessment criteria of internet health information. Discussion and Conclusion: Results of this paper were compared with the previous studies from the literatures. Contrary to the previous studies in the literature, there was significant difference in importance of assessment criteria between the persons in medical institutions and the persons not in medical institutions. In order to apply the study results to develop health contents for consumer, there is a need for further upgrade the proposed assessment criteria based on expert opinion.

The purposes of this study were to identify buyers' need criteria on product/vendor selection criteria of apparel buyers in department store and to investigate the relatonships among buyers' need criteria, information search behavior, types of buying task and influential factors on buying behavior of buyers(individual characteristics, organizational characteristics, and customer perception characteristics). A questionnaire was developed to measure research subjects based on theoretical study empirically. The questionnaire was administered to 159 apparel buyers of 11 department stores in Seoul. The results of empirical studies were summarized as follows. 1. The need criteria of buyers on product/vendor selection criteria were classified into five types : vendor characteristics; quality characteristics; price characteristics; brand characteristics; product characteristics and the need criteria differed significantly by influencing factors on buying behavior of buyers. 2. There were no relationships between information types and amounts of information search but information types differed significantly by need criteria and individual characteristics 3. Types of buying task were significantly different according to need criteria of buyers and organizational characteristics. 4. Buying policy of department store was significantly different according to organizational characteristics.

With an increasing awareness of information security, the market demand for better information security goods and services causes shortage in well trained information security manpower. This study analyzes the priorities of the options available to the qualitative information security manpower training policy. The analysis is conducted through four hierarchies: goals, criteria, sub-criteria and alternatives for each of which priorities are developed through the rating approach of the Analytic Hierarchy Process (AHP). 3 criteria and 8 sub-criteria are involved in the four hierarchies. The analysis result indicates that the fundamental information security technology is the most desirable.

The volume of the party wear market is gradually growing in the Korean fashion market. The study attempted to examine psychological clothing benefits as the criteria for market segmentation, and identify differences in information sources. and clothing evaluative criteria in each segmentated market. The summary of the key findings are as follows. Three segments were identified by psychological clothing benefits: pleasurably self-expressing group, fashion-seeking group, and indifferent group. The differences in search information sources between the classified groups were identified The fashion-seeking group had a higher mean score on mass media. The pleasurably self-expressing group had higher scores on advice from friends, colleagues, or companions. The differences in evaluative criteria between the classified groups were also identified. Among the evaluative criteria, the splendid boldness and polished silhouette criteria showed a marginal difference between each group. This study can contribute as a cornerstone for future studies on party wear and market strategies.
