In the companion paper, a simple but effective analysis procedure termed an Improved Modal Pushover Analysis (IMPA) is proposed to estimate the seismic capacities of multi-span continuous bridge structures on the basis of the modal pushover analysis, which considers all the dynamic modes of a structure. In contrast to previous studies, the IMPA maintains the simplicity of the capacity-demand curve method and gives a better estimation of the maximum dynamic response in a bridge structure. Nevertheless, to verify its applicability, additional parametric studies for multi-span continuous bridges with large differences in the length of adjacent piers are required. This paper, accordingly, concentrates on a parametric study to review the efficiency and limitation in the application of IMPA to bridge structures through a correlation study between various analytical models including the equivalent single-degree-of-freedom method (ESDOF) and modal pushover analysis (MPA) that are usually used in the seismic design of bridge structures. Based on the obtained numerical results, this paper offers practical guidance and/or limitations when using IMPA to predict the seismic response of a bridge effectively.

This article focuses on the history and evolution of the US court's attitude towards unilateral arbitration and dispute resolution clauses, but also considers the practical approach of national courts to theses clauses. It goes on to consider some potential pitfalls in the operation of unilateral clauses, which should be borne in mind when developing a strategy for bringing or defending a claim which falls within the scope of a unilateral clause. There can be few objections to the general validity of unilateral arbitration clauses. The principle of party autonomy is the driving force behind international arbitration and, provided it is tolerably clear that the parties intended the arbitration clause to operate unilaterally, courts should be reluctant to interfere with the parties' agreement. There are also no persuasive public policy reasons why such clauses should not be upheld in commercial agreements. In addition to the issue of whether such unilateral clauses are permissible under certain law, it is important to be aware of how they should properly operate in practice, that is, useful guidance on the subject of the proper operation and effect of such clauses where they are intended to be used to enable a party to decide whether, and in what circumstances, a claim should be referred to court or to arbitration.

Purpose: This quasi-experimental study was done to develop image-use medication education for older inpatients and to evaluate the effects on their knowledge, self-efficacy, and misuse of medication. Methods: Fifty nine elders (experimental group - 30, and control group - 29) received medication education once a week for 3 weeks. Data were collected before (pretest), right after (post 1), and 4 weeks after the program finished (post 2). Drug Use Knowledge Scale, Self-efficacy for Appropriate Medication Use Scale, and Drug Misuse Scale were used. Analysis included descriptive statistics, $x^2$ test, repeated measured ANOVA. Results: Findings showed significant differences in knowledge of medication and drug misuse between groups according to time(pretest, post 1, and post 2). At post 1 and post 2, knowledge and self-efficacy levels were significantly higher and misuse scores were lower in the experimental group compared to the control group. Conclusion: Findings indicate that elder-tailored medication education consisting of group education and individual guidance with images is effective and practical for medicine safety in elderly inpatients. Moreover, it could lead to a healthier life for elders, even elders with multiple chronic diseases and taking several medications.

We have examined the perception of teachers and students in elementary schools toward the frontier science and analyzed corresponding contents in science textbooks in Korea and the U. S. in order to promote a good guidance for the frontier science education. We prepared separate questionnaires for teachers and children, respectively, and analyzed the responses obtained from 244 teachers and 1,000 students in five elementary schools. For the analysis of how to introduce the frontier science, we investigated textbooks such as Science, Society and Practical Arts of Korean elementary school, and an American science textbook published by Scott Foresman. This study revealed that teachers are well aware of the importance of the frontier science, however, they are inactive in conducting the subject in class rooms because of their insufficient scientific knowledge and poor environment for teaching. It has been found that children had strong interest in the frontier science, however, opportunities to learn the topic are not properly provided. The frontier science m the American science textbook turned out to be more systematically introduced than that in Korean ones.

다양한 멀티미디어와 정보통신 기술의 발달로 인하여 국내 대학도서관들의 도서대출량이 급감하고 있을 뿐만 아니라 대학생들의 독서량도 급감하고 있다. 이에 대학도서관들은 교양학습의 중심으로 교양독서 진흥을 위한 다양한 행사를 진행하고 있지만 대학생들에게 실질적인 도움이 되지 못하고 있다. 이를 해결하기 위하여 현재 국내에서 활발하게 독서행사를 실시하고 있는 4개의 대학도서관을 대상으로 벤치마킹하였다. 결과에 의하면 교양필독서로 추천된 도서는 대학교육시스템 속에서 의무적으로 읽을 수 있는 방안이 적당하고, 도서관 독서행사로는 내적인 동기부여를 할 수 있는 독서토론이 효과적이며, 독서교육에는 글쓰기를 통하여 개인의 직접 경험과 독서 경험을 일체화 시킬 수 있는 방법이 바람직하다. 이를 위해서 대학생들에게 독서지도를 담당할 사서들의 독서력이 필요하다.

Soil microbial communities are immensely diverse and complex with respect to species richness and community size. These communities play essential roles in agricultural soil because they are responsible for most of the nutrient cycles in the soil and influence the plant diversity and productivity. However, the majority of these microbes remain uncharacterized because of poor culturability. Next-generation sequencing techniques have revolutionized many areas of biology by providing cheaper and faster alternatives to Sanger sequencing. Among them, amplicon pyrosequencing is a powerful tool developed by 454 Life Sciences for assessing the diversity of complex microbial communities by sequencing PCR products or amplicons. This review summarizes the current opinions in amplicon sequencing of soil microbial communities, and provides practical guidance and advice on sequence quality control, aligning, clustering, OTU- and taxon-based analysis. The last section of this article includes a few representative studies conducted using amplicon pyrosequencing.

An increasing number of transactions in the bilateral trade between Korea and China rely on collection and remittance, resulting in an increase in exporters' demand for trade financing. Therefore, there is a need to vitalize forfaiting transactions using drafts or promissory notes, which are based on the collections. In the forfaiting transactions, exporters transfer a payment claim to forfaiters on a non-recourse basis through a without recourse endorsement. However, forfaiters do not know importers' creditworthiness and ability to repay drafts or promissory notes; thus, they need a bank aval as a means of credit support. In forfaiting using aval, the drafts or promissory notes are transferred internationally. However, there is no internationally unified law that regulates drafts and promissory notes, and the governing laws related to such drafts and promissory notes do not accept the "principle of party autonomy." Therefore, there is no other choice but to apply the laws of a certain country, in the event of any dispute relating to such drafts or promissory notes. This paper examined forfaiting using aval from the comparative law perspective, focusing on the "Law of China on Negotiable Instruments." The results of this study may to provide businesses involved in international trade with practical guidance and assistance when using forfaiting with aval, especially in trade with China.
