We report our study on the implementation of Q tensor approach into three-dimensional finite element method (FEM) numerical solver. The comparative simulation results demonstrated the possibility of a different director configuration in between Q tensor method and vector method. The comparative study confirmed that Q Tensor implementation is more appropriate for OCB analysis than the vector method.

For many social scientists, the comparative method has been a part of the common enterprise of describing, explaining, and developing theories about socio-cultural phenomena. However, it is rare that comparison has been methodologically considered in architectural history in spite of the usefulness for understanding the similarities and differences among architectural styles. This research emphasizes the importance of comparative methodology in architectural history and proposes an example which can be introduced from the comparative method for social studies. The application in this study is based on the assumption that an architectural phenomenon is a kind of social phenomenon and comparative method in social study can be applied to architectural history. The method is to generate and test hypotheses through establishing functional correlation between variables treated as the objective facts that differentiate one type of building from another.

The purpose of this study is to find research areas that were less represented by the researchers of mathematics textbooks and to provide feedback for the research and development of mathematics curriculum and textbooks. In order to complete this study, we analyzed comparative studies of mathematics textbooks published in Korean. This study analyzed 107 comparative studies published until recently based on following aspects: countries studied (North Korea, U.S.A., and Japan), Math curriculum studied (6th and 7th mathematics curriculum), and Math contents studied (probability and statistics) and etc. The result of this study suggests that the content area of creative problem solving was particularly less represented by the studies published and require more concern from the mathematics education researchers

As decision makers do not make optimal decisions in practice despite the existence of optimal solutions in many models, there has been a rising interest in behavioral operations management recently. In this study, we aim for a comparative study to analyze the inventory decisions in Korea, America, and China, by conducting the same newsvendor experiment in Korea and compare the results with those of previous studies. From the comparative analysis, some national characteristics in decision-making processes have been observed but there is lowly significant difference in order quantities among the three groups. Korean students show lower level of understanding in demand distributions and tendencies of anchoring on the mean demand and being risk-averse. The finding that individuals make their own decisions differently based on their different behaviors suggests that we need to consider individual approach in analyzing human decision-making processes rather than adapting aggregate approach.

본 연구에서는 '부당한 비교표시 광고'의 법리적 특성은 어떻게 해석되어 적용되고 있는가를 알아내기 위해 공정거래위원회의 심결사례를 분석하였다. 7년 동안 '부당하게 비교하는 표시 광고'로 분류된 심결사례는 38건이었으나 실제로 부당 비교표시 광고로 심결된 사건은 17건이었다. 이러한 오류의 이유는 위반 내용 중 '비교'라는 표현이 있는 경우는 모두 비교광고의 범주에 포함시켰기 때문으로 추정된다. 결과에 의하면, 부당 비교표시 광고의 '부당성' 유형으로는 비교대상 5건, 비교기준 11건, 비교내용 7건 및 비교방법 4건(중복 적용 수)으로 나타났는데 각 부당행위에는 '기만' 또는 '허위 과장'적 요소가 중복으로 존재하고 있었다. 이와 같은 결과들로 미루어 부당한 비교표시 광고의 '부당성'의 의미를 '기만,' '허위 과장', '비교' 및 '비방' 등의 개념들과 상호 복합적으로 고려하여 보다 명확히 규명할 필요가 있으며 의미 적용적 측면에서 합리적인 법 운용방법을 모색해야 할 것이다. 그리고 이러한 개선방안들은 무엇보다도 표시 광고법의 입법목적인 소비자 보호적 차원에서 이루어져야 할 것이다.

본 연구는 비교광고의 메시지 유형이 광고태도와 메시지 수용의도에 미치는 영향을 분석하고 나아가 소비자 정서와 제품유형의 조절효과를 분석하고자 실시되어졌다. 제품유형을 실용재와 쾌락재로 분류하고, 비교광고 메시지는 일면과 양면 메시지로 분류하여 총 4가지 유형의 광고물을 배포하였다. 소비자 정서를 조작하기 위해 절반의 응답자들에게 실험 전 즐겨 마시는 음료수를 제공하여 자연스러운 상황을 연출하였으며, 나머지 절반의 응답자들에게는 아무것도 제공하지 않고 실험을 진행하였다. 실증분석 결과, 비교광고의 메시지유형은 광고태도와 메시지 수용의도에 유의한 영향을 미치는 것으로 나타났다. 나아가 소비자 정서와 제품유형의 조절효과도 모두 유의한 것으로 조사되었다. 본 연구 결과는 광고메시지의 측면성 효과를 비교광고에 접목시켜 분석했다는 점에서 이론적 시사점을 제공하고 있다. 뿐만 아니라 소비자 정서와 제품유형의 조절효과를 검증함으로써 해당분야의 실무자들에게 시사점을 제공할 수 있을 것으로 생각된다.

Background: Xylazole (Xyl) is a veterinary anesthetic that is structurally and functionally similar to xylazine. However, the effects of Xyl in vitro remain unknown. Objectives: This study aimed to investigate the anesthetic mechanism of Xyl using fetal rat nerve cells treated with Xyl. Methods: Fetal rat nerve cells cultured for seven days were treated with 10, 20, 30, and 40 ㎍/ mL Xyl for 0, 5, 10, 15, 20, 25, 30, 45, 60, 90, and 120 min. Variations of amino acid neurotransmitters (AANTs), Nitric oxide-Cyclic GMP (NO-cGMP) signaling pathway, and ATPase were evaluated. Results: Xyl decreased the levels of cGMP and NO in nerve cells. Furthermore, Xyl affected the AANT content and Na⁺-K⁺-ATPase and Ca²⁺-Mg²⁺-ATPase activity in nerve cells. These findings suggested that Xyl inhibited the NO-cGMP signaling pathway in nerve cells in vitro. Conclusions: This study provided new evidence that the anesthetic and analgesic effects of Xyl are related to the inhibition of the NO-cGMP signaling pathway.

The study examined and compared relationships among self-esteem, self-efficacy, and academic achievement of children in poverty and the comparative groups. The subjects of this study were 97 elementary school students who had benefited from the free meal project and 97 students as the comparative group who did not receive the benefit. Descriptive statistics, Cronbach's ${\alpha}$ tests, and multiple regression analysis were employed to analyze the data. The results showed that academic scores of the comparative group were statistically higher than those of children in the poverty group in Korean language, mathematics, science, and sociology. Also, self-esteem of children in the poverty group was lower than that of the comparative group's in terms of leadership and popularity. The poverty group also showed lower self-efficacy in self-regulated efficacy tasks. Finally, multiple regression analysis demonstrated that different sub-factors of self-esteem and self-efficacy predicted the academic achievement of children in poverty group and the comparative groups.

This study examined the comparative advantage of manmade textile (MMT) industries in the United States (US) and South Korea (SK). The Revealed Comparative Advantage (RCA) framework was used to assess the MMT industries' performance in both countries from 2004 to 2013. With the recent ratification of the United States-South Korea Free Trade Agreement (KORUS FTA), it is important to understand the current state of these industries. Using UN Comtrade export data, the RCA index values were calculated and analyzed for 27 MMT commodities, three aggregate groups, and the whole industry. It was found that SK had a consistent comparative advantage for the whole industry. Furthermore, SK had a larger number of products with a comparative advantage. The research findings indicate that the MMT industry in SK is likely to outperform the US following the complete ratification of the KORUS FTA.

This paper will discuss the difference between self assessment of voice disorders and the hearer voice assessment of a comparative group of normal subjects. The study was conducted on 25 voice disorder subjects and 32 hearers of a comparative group of normal subjects. The results are as follows. Firstly, in K-VHI and VHI-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Likewise, in K-VQOL and VRQOL-H, the hearers of the comparative group of normal subjects perceived more serious voice disorders than the voice disorder group in all sub-domains. Secondly, the hearer voice assessment of the comparative group of normal subjects showed no difference in gender regarding the perception of the severity of voice disorder issues. Thirdly, the hearer voice assessment of the comparative group of normal subjects states that in the emotional aspects of VHI-H, professional voice users perceive more serious voice disorders than others. Accordingly, in VRQOL-H, there was no difference in use of the voice between professionals and others.
