In many international financing transactions Korean companies are required to issue a guarantee. Thus far, however, legal issues on international guarantees have not been fully discussed in Korea. This is partly because most of the international guarantees are governed by a foreign law such as English law or the laws of the State of New York. In this articles the author examines major concepts or terms and conditions of a typical international guarantee, e.g., language on consideration, primary obligor, joint and several guarantee, unconditional and irrevocable guarantee, continuing guarantee, right of subrogation, representations and warranties, covenant or undertaking, currency indemnity, assignment, participation, governing law and jurisdiction clause, etc. For reference, standard forms of a guarantee and a standby letter of credit are attached to the article. In examining the terms and conditions, the author compares them with similar or equivalent concepts under Korean law. The author further discusses some Korean law issues that may arise under international guarantees governed by a foreign law. These issues include the application of the ultra vires doctrine under Article 34 of the Civil Code of Korea, the validity of an international guarantee which a Korean company has issued in violation of the guarantee ceiling set under Article 10 of the Law on Monopoly Regulation and Fair Trade of Korea and the validity of an international guarantee which a Korean party has issued in violation of the Foreign Exchange Transaction Law. In addition, the author discusses some issues under a so-called independent guarantee and a standby letter of credit. In this regard, reference is made to the Uniform Rules for Demand Guarantee (URDG), International Standby Practices (ISP98) and the Convention on Independent Guarantees and Stand-by Letters of Credit adopted by the United Nations in 1995. Finally, the author examines major terms and conditions of typical comfort letters and discusses some legal issues, such as the binding force of the comfort letter. In dealing with the issues the author underscores that to the extent the issues are not properly dealt with by an international norm such as Uniform Customs and Practice for Documentary Credits or ISP 98, the issues must be analyzed by reference to the governing law of the relevant instrument.

This study analyzed reference data for the physics section in science guidebooks for the third-sixth grade in elementary schools, according to the 2015 revised curriculum. It analyzed the reference data by categorizing them in terms of subjects, objectives and presentation forms and the visual data used in the reference data by categorizing their types. The findings show that the ratio of the science knowledge type was highest (53.8%) among the subjects of reference data in guidebooks for the science section, followed by the application to real life, and then, supplementary inquiry experiments and activities. The ratios of other types such as advanced science, environment, scientists and science history were, however, less than 1%, so they need to be improved. The ratio of knowledge provision was highest (40.5%) among the objectives of reference data but the ratios of conceptual supplementation and deepening were similar in ratio. Meanwhile, While the expository type (88.4%) accounted for most of the present forms of reference data, and photographs and illustrations (93.6%) also accounted for most of visual data suggested with reference data. Thus more various types of presentation forms and the extension of visual data seemed to be needed. This study is expected to provide some suggestions for the meaningful use of reference data in guidebooks for teachers and for the development of science guidebooks for teachers in elementary schools.

In learning stage of the preliminary Cut-off indoor positioning scheme, RSSI and UUID data received from beacons at each reference point(RP) are stored in fingerprint map. The fingerprint map and real-time beacon information are compared to identify the nearest K reference points through which the user position is estimated. If the number of K is zero, this scheme cannot estimate user position. We have improved the preliminary Cut-off scheme to get the estimated user position even in the case. The improved scheme excludes the beacon of the weakest signal received by user mobile device and identifies neighborhood reference points using the other beacon information. This procedure are performed repetitively until K > 0. The simulation results confirm that the proposed scheme outperforms K-Nearest-Neighbor (KNN), Cluster KNN and the conventional Cut-off scheme in terms of accuracy while the constraints are guaranteed to be satisfied.

본 논문에서는 객체지향 패러다임을 적용함으로써 도메인 종속적인 시소러스를 효율적으로 구축하고 관리할 수 있는 객체기반 시소러스 시스템을 설계하고 구현하였다. 이때, 객체지향 패러다임은 시소러스의 구축, 개념 브라우징 그리고 질의기반 참조 기능에 적용된다. 이 시스템에서 객체지향 패러다임의 상속 메커니즘은 시소러스에 표현된 개념들간의 관계를 구조적으로 파악할 수 있게 하여 전문가가 시소러스를 반자동 방식으로 구축할 수 있도록 지원한다. 특히, 방대한 시소러스를 여러 전문가들이 서로 다른 호스트에서 구축할 경우, 이 메커니즘에 의해 파악된 정보는 시소러스의 의미적 일관성을 유지시킬 수 있도록 도와주며, 전문가가 직접 개념들간의 관련 정도를 모두 명시해야하는 부담을 최소화할 수 있다. 객체기반 시소러스 시스템은 또한 질의기반 참조 기능과 추상화 방식의 개념 브라우징 기능을 제공한다. 이 기능들은 검색 질의에 이용될 시소러스 개념들을 사용자가 사전에 탐색해 봄으로써 쉽게 검증할 수 있게 한다. 특히, 이 질의 검증 과정은 높은 정확률을 요구하는 도메인에 적절히 이용될 수 있다.

An efficient method of formulating the equations of motion of multibody systems is presented. The equations of motion for each body are formulated by using Newton-Eulerian approach in their generic form. And then a transformation matrix which relates the global coordinates and relative coordinates is introduced to rewrite the equations of motion in terms of relative coordinates. When appropriate set of kinematic constraints equations in terms of relative coordinates is provided, the resulting differential and algebraic equations are obtained in a suitable form for computer implementation. The system geometry or topology is effectively described by using the path matrix and reference body operator.

Selection procedures are proposed for selecting the 'best' industrial process with the smallest fraction defective. For normally distributed industrial processes, this is equivalent to selecting in terms of coefficients of variation. For the case of known vairances, selection procedures by Bechhofer (1954), and Bechhofer and Turnball (1978) are appropriate. We treat this problem for the case of uknown variances with or without reference to a standard. The large sample solutions of design constants are tabulated and the performance of these approximate solutions are investigated.

The purpose of this study was to compare the effectiveness of programmed instruction versus lecture and discussion method on the knowledge of basic reference sources among undergraduate library and information science students. The hypotheses of the study were: 1. Programmed instruction will be more effective than the lecture/discussion method with regard to academic achievement. 2. There will be a significant difference in learning time between the experimental and the control groups. Seventy-eight library and information science students were participated m the study from the two universities in Chungchong Province. A programmed instruction manual, including 4-types of reference sources-dictionary, encyclopaedia, bibliography, indexes and abstracts, 40-item multiple choice post-test, and a questionnaire for the students' attitude toward programmed instruction were developed specifically for this research. The post-test only control-group design was selected for this experimental study. Students were given instruction on the specific reference titles in dictionary, encyclopedia, bibliography, indexes and abstracts. The control group was instructed by the lecture and discussion method while the experimental group completed a programmed instruction manual by themselves. Both the control and the experimental group were tested right after the instruction of 4-types of reference sources. In addition, a questionnaire asking students' attitude toward programmed instruction was administered to the experimental group. The findings from this study are summarized as follows: 1. The results showed that there were no significant difference in the mean of the post test score between the two groups. Therefore, programmed instruction is viable as an alternative method of instruction in the teaching of reference sources. 2. There was a significant difference in the mean of time spending for the leaning of bibliography, indexes and abstracts between the two groups. Accordingly, programmed instruction proved to be more efficient than the conventional lecture/discussion method in terms of learning time. 3. Students showed positive response to programmed instruction and evaluated it very interesting and challenging. In conclusion, the programmed instruction method was just as effective as the lecture/discussion method in the teaching of reference sources. And students' attitude toward the programmed instruction was favorable enough to secure a continued use of this method for the teaching of reference sources.

The present study, focusing on the stress-shift constructions, examines the tendency of young children to give wrong wide scope interpretation in language acquisition and questions the validity of the guess pattern hypothesis argued by Grodzinsky & Reinhart (1993). According to the hypothesis, children know that they have to construct a reference-set, keep two representations in working memory, and check whether the interpretation needed in the given context justifies selection of competing reference sets, but their working memory is not big enough to hold the materials needed to complete the execution of this task. Hence they give up and resort to a guess. 1 carried out an experiment of 16 Korean children aged 3;9 to 6;2 to find out whether children have more difficulty in the interpretation of stress-shift constructions than of constructions with a nuclear stress, and therefore perform the interpretation of the former by guessing. Assuming that the tendency is caused by a deficiency in contextual computation rather than reference set computation, I try to explain it in terms of pragmatic considerations.

PWM controlled line-side converters of modern ac traction locomotives inject harmonic currents into the feeding overhead line. This causes problem of electromagnetic interference. Passive and Active filters are usually provided for a reduction of the line harmonics. Active filters are more reasonable than passive filters in terms of weight and space of the filters. Successful control of active filters requires an accurate harmonic current reference. A technique to generate the harmonic current reference is proposed in this paper. The analysis is performed in frequency domain and its effectiveness is verified by simulation.
