  • A study of scientific methods in a study of comparative on the oriental medicine and the western medicine evidence to find on the cause-effect relationship. The rationality in a study of process and the confidence in a study of result were improved by a study of methods on the cause-effect relationship. Also a comparative study on the Jeong(精) of the oriental medicine and the cell of the western medicine, after established a model of the cause-effect relationship secured a suitability of a comparative subject and operationalization of a comparative variable to the rationality in a study of process. The Jeong(精) and the cell are the character of a unit and the character of a matter on the human body. The Jeong(精) and the cell are a point of similarity in the function. The Jeong(精) and the cell are a relation in the mechanism. Our paper reviewed a study of comparative methods on the oriental medicine and the western medicine, and suggest an identic interpretation on the human body.

  • In this paper, I suggest methodological ways of studying comparative literature regarding ongoing discussions of world and national literature. The role of comparative literature studies has widened in the contemporary era, in which nations have become rapidly entangled and the concept of the world as a unified entity is under question. In this regard, I critically review the traditional principles of the hospitality of cosmopolitanism and the exclusivity of the borders of national literatures. Further, I suggest that scholars adopt the concept by Sigmund Freud of "unfamiliar familiarity" as a methodological motive for studies of comparative literature. Based on this concept, scholars can further develop the unique methods of the discipline of comparative literary studies for teaching and research amidst the ongoing phenomenon of globalization. They can also use these methods to simultaneously contribute to solving the problem of "comparison without a unifying category of the world," as revealed by the results of deconstructional and postcolonial studies. Regarding community-based discussions of literature, I introduce the "bridge and door" metaphor, put forth by Georg Simmel, as a key concept in methodological consideration of translation and in comparative literary studies. In this paper, adopting the metaphor of the bridge and door as an intertextual and social model for comparative studies, I define the new role of comparative literary studies in literary transnationalism, which is particularly necessary when different languages and cultures overlap and become entangled. Regarding the rapidly changing contemporary world community, comparative literary studies, as an experimental discipline, is uniquely capable of examining this kind of community, which forms itself beyond and beneath individual nations.

  • 이 논문은 교육평가학과의 관계를 점검함으로써 비교교육학의 학문적 위상을 정립하는 데 도움을 주려는 목적으로 작성되었다. 비교교육학은 교육학의 분과 학문이면서 교육학의 다른 분과 학문들을 포괄할 수도 있다는 점에서 독특한 성격을 지닌다. 그리고 교육평가학은 평가의 내용을 다루기도 하지만 평가 방법론이 연구 영역에 포함된다는 특징을 지닌다. 교육평가학과 비교교육학 간 접점으로는 먼저 점차 확대되고 있는 국제비교평가를 들 수 있다. 국제비교평가는 1960년대 12개국의 수학교육을 비교하기 위해 실시된 국제수학연구를 필두로 대상 과목과 참여국가가 점점 확대되고 있다. 국제비교평가는 단지 참여국의 순위 경쟁이 목적이 아니라 각국의 교육과정 및 교육실천을 다각도로 비교함으로써 교육 개선을 위한 시사점을 제공하기 위해 실시되고 있다. 국제비교평가에는 다집단 분석을 실시할 수 있으며, 특히 국가 간 사회문화적 차이 등 측정구인 외의 요소가 어떻게 작용하고 있는지 밝히는 차별적 문항기능 분석이 가능하다. 또한 국제비교평가 자료는 다른 교육 자료들과 마찬가지로 위계적 구조를 지니고 있어 다층모형 또는 위계적선형모형이 적절하다. 따라서 문항반응이론을 확장시킨 다층문항반응이론을 적용할 수 있으며, 이를 통해 국가 간 차이에 대한 다차원적 진단이 가능하다. 교육평가학의 방법론적 진보에도 불구하고 비교 교육학과의 간극으로 인해 그 도구들은 적절히 사용되지 못하고 있다. 이를 해결함으로써 비교 교육학은 학문으로서 진일보할 수 있을 것이다. 결론적으로 방법론을 쉽게 풀어 널리 알림으로써 연구자가 도구를 손쉽게 사용할 수 있도록 하는 교육평가 학계의 노력과 함께 이러한 도구들을 사용함으로써 보다 정밀하고 정확한 분석을 통해 정책적 시사점을 도출하고자 하는 비교교육 연구자들의 노력이 함께 요구된다.

  • Secure digital payment is critical in the successful shaping of global digital business. Digital payments are increasingly being used as a substitute to traditional payments, contributing markedly to the efficiency of the economy. The focus of every digital business transaction is to minimize risks arising from transactions. It is essential to ensure the security of digital payment whether used in internal networks or over wireless Internet. This paper analyses secure digital payment methods from the viewpoint of systemic security and transaction security. According to comparative analysis of digital payment models, this paper proposes a comparative analysis framework to investigate and evaluate secure digital payment. In conclusion, the comparative analysis framework, comparison of digital payment models and mobile payment models proposes a useful academic and practical foundation to enhance the understanding of secure digital payment methods. It also provides academic background and practical guidelines for the development of secure digital payment systems.

  • Comparison studies of the Quantitative Structure Activity Relationship (QSAR) methods with new imidazo-quinolinedione derivatives were conducted using Comparative Molecular Field Analysis (CoMFA), Comparative Molecular Similarity Indices Analysis (CoMSIA), and the Hologram Quantitative Structure Activity Relationship (HQSAR). When the CoMFA crossvalidation value, q2, was 0.625, the Pearson correlation coefficient, r2, was 0.973. In CoMSIA, q2 was 0.52 and r2 was 0.979. In the HQSAR, q2 was 0.501 and r2 was 0.924. The best result was obtained using the CoMSIA method according to a comparison of the calculated values with the real in vitro cytotoxic activities against human ovarian cancer cell lines.

  • Objectives : Since The Journal of Korean Acupuncture and Moxibustion Society(JKAMS) started publishing in 1984, randomised controlled trials(RCTs) and non-randomised clinical studies(NRSs) consistently have increased in quality and quantity. There has been no study on quality assessment of NRSs. Thus, this study evaluted non-randomised comparative clinical trials in the JKAMS to assess the quantity and quality. Methods : Upon extracting NRSs for assessing the intervention effects from all the articles published in the JKAMS from 1984 to 2009, assessments were made on methodological index for non-randomised studies(MINORS). Also, the analysis were made upon the proportion of non-randomised comparative clinical trials within original articles. The mean scores by research methods and years, and total scores and mean scores of yearly research methods were analyzed. Results : A total of 44 trials on non-randomised comparative clinical trials were selected. In 1980s, 4.3% of the total selected original articles, in 1990s, 4.1%, and in 2000s 14.2% were NRSs. According to the research designs, the mean scores of MINORS were Case-control study 18.3, Controlled before and after 18.5, Quasi randomised trial 18.5, and non randomised trial 17.9(out of 24), respectively. Cross-sectional study was the most frequently used(41.9%). Conclusion : Although NRSs consistently increased in quantity, the assessed mean scores were low and most articles used Cross-sectional study. Thus, there should be studied using appropriate research methods in the future.

  • Over the last years, a number of different path following methods for the autonomous parking system have been proposed for tracking planned paths. However, it is difficult to find a study comparing path following methods for a short path length with large curvature such as a parking path. In this paper, we conduct a comparative study of the path following methods for perpendicular parking. By using Monte-Carlo simulation, we determine the optimal parameters of each controller and analyze the performance of the path following. In addition, we consider the path following error occurred at the switching point where forward and reverse paths are switched. To address this error, we conduct the comparative study of the path following methods with the one thousand switching points generated by the Monte-Carlo method. The performance of each controller is analyzed using the V-rep simulator. With the simulation results, this paper provides a deep discussion about the effectiveness and limitations of each algorithm.

  • Various studies have been undertaken in order to effectively understand customer requirements. Kano proposed a dualistic approach, physical fulfillment and customer satisfaction, to differentiate Attractive, Must-be, One-dimensional quality attributes. As there were a few limitations on the Kano's method, researchers have proposed improved methods. However, there have been few empirical evidences that the improved methods are superior to the original Kano's method for identifying relevant quality attributes. The objective of this study is to provide a comparative study on Kano and improved Kanomethods based on empirical analysis of quality attributes on University services. For the analysis of the questionnaire formats, the Kano's original 5 scale questionnaire is more effective than improved methods, direct and 3 scale questionnaire. For the analysis of evaluation methods, the original Kano and Timko's method using the evaluation table are more effective than quantifying methods, Domouchel and Lim's methods.
