This study was conducted to compare the physical shapes of Korean males in their 20s between those residing in Yenbien, China and those living in Korea. Measurements were checked fur 57 items on 167 Korean male residents in Yenbien, China and 295 Korean male residents in Seoul and the other large cities around it. The conclusions are as follows: 1. The comparison of 58 items in physical measurements of Korean male residents in China and those in Korea showed differences in 49 items. Korean male residents in China had the smaller physical shapes short in limbs and height. 2. The comparison of the factor analysis results for physical measurements did not reveal big differences. In terms of the contribution of variables, however, obesity played an exceptionally large role fur Korean residents in China, while the importance of obesity and vertical length were similar for those in Korea. 3. The comparison of the physical shapes according to the grouping resulted in three types each for both groups, with different features for individual types. Korean residents in China were grouped according to the obesity factor rather than the changes in height, while those in Korea were classified according to both vertical length and obesity.

This study investigates an association among Facebook users' upward comparison (e.g., envy), social support (e.g., favorable comments and like), and life satisfaction, putting their self-esteem as a mediating variable. For this analysis, 1,332 female and male Facebook users in Seoul and other four cities in South Korea were surveyed. Structural equation modeling including confirmative factor analysis were employed as quantitative analysis methods. Results show that Facebook users' upward comparison with other users and social support significantly impact their satisfaction mediated by their self-esteem. Specifically, when users feel envious of other users, this emotion lowers their self-esteem, and subsequently, the self-esteem reduces their satisfaction. On the other hand, sufficient social support for users positively affects their self-esteem, which leads to the increase of their satisfaction. The present study is differentiated from previous studies in that it focuses on Facebook users' emotional changes in the process of sharing massive amounts of posts and finds a stepwise relationship among their feelings, including self-esteem as a mediating variable. Additionally, this study is the first to verify a situation when Facebook users' envy of other users' posts affects the decline in their satisfaction through the mediation of their self-esteem.

A grouping process through the similarity comparison is required to effectively classify and respond a malicious code. When we have a use of the past similarity criteria to be used in the comparison method or properties it happens a increased problem of false negatives and false positives. Therefore, in this paper we apply to choose variety of properties to complement the problem of behavior analysis on the heuristic-based of 2nd step in malicious code auto analysis system, and we suggest a similarity comparison method applying AHP (analytic hierarchy process) for properties weights that reflect the decision-making technique. Through the similarity comparison of malicious code, configured threshold is set to the optimum point between detection rates and false positives rates. As a grouping experiment about unknown malicious it distinguishes each group made by malicious code generator. We expect to apply it as the malicious group information which includes a tracing of hacking types and the origin of malicious codes in the future.

As a result of comparison analysis on body types of Korean women in their twenties and Korean women residing in Japan, the following results had been found. 1. The comparison of 49 items in physical measurements between the Korean women in their 20's and Korean women residing in Japan resulted in the differences in 33 items. 2. The comparison of the factor analysis results for physical measurements did not reveal big differences. 3. The comparison of the physical shapes according to the grouping resulted in three types each for both groups, with different features for individual types. Women residing in Korea were classified into tall and normal body, normal height with obese body, and short and thin body. Women residing in Japan showed different characteristics with tall and obese body, short and thin body and normal height with obese body. As a result of this study, identical ethnic group was found to take on different body types resulting from sociocultural differences and difference in eating habits if their place of residence differs for a long time.

Much research has already been done on Donguibogam. However, comparison of specific characters was not done because researchers found it difficult to compare different editions of the text in one place. Recently, important editions have been published on the Internet, making comparison possible. In this paper, researchers compare eight editions Donguibogam, including the original edition published in 1613 and seven other editions corrected by the Naeuiwon (Joseon Dynasty National Medical Center). The comparison results were summarized and tabulated. The results of the comparison are analyzed and presented in this article as a chart. The result of comparing the characters and the analyzed graph were in agreement. The authors propose that all written and electronic publications of Donguibogam should refer to other editions implied, quoted or referenced within the text and including with proper citations, and reference the original and first edition. Inadequate referencing will pollute future knowledge of this foundational text of Traditional Korean Medicine and may result in perpetration of mis-information. Based on accumulated knowledge and study of historical Korean Medicine texts, the Namsan edition made a mistake in the editing process. The year of publication of Gabsul-yoengyoeng-gegan Edition needs to be studied again and corrections made where appropriate.

In the early stage of weapon system acquisition process, acquisition policy is necessarily established to acquire weapon system in a faster, better, cheaper way. Several alternatives, such as "buy", "domestic research and development", and "technical corporative production", can be considered for the best acquisition policy making. However, the comparison factors for those alternatives have different metrics and values. Therefore, the aim of this paper is to suggest KAAM(Knowledge-based Alternatives Analysis Model) as a scientific method to compare the alternatives having such different metrics and values and giving a weighted and normalized single measurement for the easy comparison. KAAM is a hybrid model incorporating Satty technique, Delphi/Shang method, Consensus method, and SAW method. KAAM is implemented on Microsoft Excel environment and provided tabular form user interface. Finally, an illustrative example is shown using KAAM.

Instead of extracting every selected harmonic component, the current reference of selective active power filter (APF) can be also obtained by filtering out the fundamental component from distorted load current for computation efficiency. This type of mixed current reference contains kinds of harmonic components and easily involves noises. In this condition, selective harmonic compensation must be realized by the current controller. With regard that selectivity is the most significant feature of controller, this paper presents specific comparison analysis between two types of resonant controllers: proportional-resonant (PR) controller and vector-resonant (VR) controller. The comparison analysis covers the relations, performances, and stability of both controllers. Analysis results conclude that the poorer selectivity of the PR controller could be relatively improved, but limitations from system stability make the improvement hardly realized. By contrast, the VR controller exhibits excellent selectivity and is more suitable for selective APF with mixed current reference. Experimental results from laboratory prototype validate the reasonability of analysis. And the features of each resonant controller are concluded.

Objectives:The purpose of this study is to 1) conduct a discrimination analysis of schizophrenia and bipolar affective disorder using MMPI profile through artificial neural network analysis and logistic regression analysis, 2) to make a comparison between advantages and disadvantages of the two methods, and 3) to demonstrate the usefulness of artificial neural network analysis of psychiatric data. Procedure:The MMPI profiles for 181 schizophrenia and bipolar affective disorder patients were selected. Of these profiles, 50 were randomly placed in the learning group and the remaining 131 were placed in the validation group. The artificial neural network was trained using the profiles of the learning group and the 131 profiles of the validation group were analyzed. A logistic regression analysis was then conducted in a similar manner. The results of the two analyses were compared and contrasted using sensitivity, specificity, ROC curves, and kappa index. Results:Logistic regression analysis and artificial neural network analysis both exhibited satisfactory discriminating ability at Kappa index of greater than 0.4. The comparison of the two methods revealed artificial neural network analysis is superior to logistic regression analysis in its discriminating capacity, displaying higher values of Kappa index, specificity, and AUC(Area Under the Curve) of ROC curve than those of logistic regression analysis. Conclusion:Artificial neural network analysis is a new tool whose frequency of use has been increasing for its superiority in nonlinear applications. However, it does possess insufficiencies such as difficulties in understanding the relationship between dependent and independent variables. Nevertheless, when used in conjunction with other analysis tools which supplement it, such as the logistic regression analysis, it may serve as a powerful tool for psychiatric data analysis.
