It is important to construct a firm basis for accusing potential violators of academic integrity in order to avoid spurious accusations and false convictions. Educational researchers have developed many statistical methods that can either uncover or confirm cases of cheating on tests. However, most of them rely on simple correlation-based measures, and often fail to account for patterns in responses or answers. In this paper, we propose a new statistical index denoted by a Standardized Signed Entropy Similarity Score to resolve this difficulty. In addition, we apply the proposed method to analyze a real data set and compare the results to other existing methods.

The most methods for intrusion detection are based on the misuse detection which accumulates hewn intrusion information and makes a decision of an attack against any behavior data. However it is very difficult to detect a new or modified aoack with only the collected patterns of attack behaviors. Therefore, if considering that the method of anomaly behavior detection actually has a high false detection rate, a new approach is required for very huge intrusion patterns based on sequence. The approach can improve a possibility for intrusion detection of known attacks as well as modified and unknown attacks in addition to the similarity measurement of intrusion patterns. This paper proposes a method which applies the multiple sequence alignments technique to the similarity matching of the sequence based intrusion patterns. It enables the statistical analysis of sequence patterns and can be implemented easily. Also, the method reduces the number of detection alerts and false detection for attacks according to the changes of a sequence size.

As the results of studies based on the Russian Activities-Oriented Theory, the gifted students in many fields have common insights for the true nature of the problem, or the actual state. From Russian Activities-Oriented Theory of view, gifted students have the ability to discern the essential elements involved in each actual state and change of state of things, and to solve the problem, based on these elements. Enhancing these abilities of the students, the educator can develop the average student into a gifted one. This study result of the Russian specialist suggests the possibility of a stream of education that can develop gifted students. Hence, this paper discussed the points and processes of formation of the Russian Activities-Oriented Theory, and inquired on what is the true nature of the problem or the meaning of actual state and how it affects the studies of the student. The paper also investigated the actual conditions of wrong learning about some mathematical concepts and discussed the role of insights to the true nature of the problem in the learning process of the student.

This study is designed to find out the determinants of housewives' caregiving behavior to their elderly parents-in-law. For this purpose, a tentative path model, constructed with major socio-demographic variables in the caregiver's family as exogenous variables, is proposed to account for caregiver's behavior to elderly parents-in-law. The model is estimated with data collected from a probability sample of housewives in Kwangju, Korea. Estimation of the model, separately for caregiver's fathers-in-law and mothers-in-law, in terms of maximum likelihood(ML) procedures in LISREL8 reveals that housewives' educational attainment, father-in-law's age, father-in-law's health status, and family size have statistically significant causal. effects on care giving behavior to fathers-in-law, and that housewives' educational attainment, mother-in-law's age, family size, and caregiving attitude have significant causal effects on caregiving behavior to mothers-in-law. Comparison of the two estimated models indicates caregiver's educational attainment, caretaker's age, and family size are prominent determinants of caregiving behavior that can be commonly generalized to the two models. Except for these common determinants, however, a nonnegligible amount of differences is identified between the two models. The findings are discussed and interpreted with suggesting some salient theoretical and policy implications.

Candidate images refer to a holistic impression of a candidate which is composed of various dimensions of attributes. This study investigated how online and offline news media, campaign media such as political ads, televised debates, and candidate web-sites, and interpersonal political talk influenced voters' images of a candidate in such dimensions as personal traits, job-performance abilities, and policy capabilities, and further their political decision making in the 17th presidential election in Korea. The analysis focused on President Lee, Myung Bak who won the election by obtaining nearly 50% of the effective votes. According to the data analyses, first, uses of offline newspapers positively influenced voters' images of candidate Lee's personal traits such as his morality, integrity, trustworthiness, and compassion, yet online news uses had an opposite effect on voters' impression of his job-performance and economic policy capabilities. Secondly, among various campaign media, television ads and candidate web-sites positively contributed to the formation of candidate Lee's images, yet showed little direct effect on vote choice, indicating that campaign media mainly indirectly influenced voters' political decision making. Each of the first, second, and third televised candidate debates revealed unique effects on image formation and vote choice. Thirdly, the network size and frequency of political talk negatively influenced image formation regarding candidate Lee's personal traits and economic policy capabilities, yet the discussion network size positively contributed to the Lee votes. Forth, among various dimensions of candidate images, voters' perceptions of candidate Lee's personal traits appeared to be the most significant predictor of the support for him.

The purpose of this study was to examine to identify factors affecting wellness of workers. This study collected questionnaire data from 172 workers from two large workplaces more than 1,000 workers are located in G city. Data were analyzed using descriptive statistics, Pearson correlation coefficient and Hierarchical regression with IBM SPSS statistics 20.0 program. Wellness of worker was correlated with exercise self-efficacy(r=.23, p<.05), autonomous motivation(r=.38, p<.001), exercise behavior(r=.61, p<.001). Hierarchical regression analysis showed that exercise self-efficacy(${\beta}=.34$, p<.001), exercise behavior(${\beta}=.30$, p<.001), subjective health status(${\beta}=-.23$, p<.001), subjective economic status(${\beta}=-.13$, p=.016) explained 57.3%(F=39.29, p<.001) of wellness of workers. Based on the finding, there is a need to develop an intervention program that consider exercise self-efficacy, exercise behavior, subjective health status and subjective economic status.

The purpose of this study is to survey aspects of factors in stages of change and decisional balance on oral examination of adults in their 20s by applying transtheoretical model. Transtheoretical model is the one that was developed in order to explain a human being's behavioral change. The stages of change consist of precontemplation stage, contemplation stage, preparation stage, action stage, and maintenance stage. Decisional balance is utilized with comprising 2 elements such as pros and cons in transtheoretical model, and was mentioned that pros and cons have unique form every behavioral stage of change. As a result of applying the regular oral examination behavior based on transtheoretical model, it was indicated to be precontemplation stage with 79 people(22.1%), contemplation stage with 156 people(43.6%), preparation stage with 38 people(10.6%), action stage with 47 people(13.1%), and maintenance stage with 38 people(10.6%). Subjects, who maintain regular oral examination, were indicated to recognize pros highly in the decision balance. Subjects, who don't have intention of receiving oral examination, were indicated to have characteristic of recognizing cons highly.
