This study aims to demonstrate the impact of BPR in reducing cost in international business organizations by analyzing the impact of decentralization, re-engineering organizational structures, re-engineering human resources, industrial process technology, improving total quality standards, and value engineering. The study population includes all the international business organizations operating in the Middle East, with the condition that they operate in at least four countries. The results showed that there is a significant effect of all dimensions of BPR in reducing costs in international business organizations operating in the Middle East. When studying the impact of the dimensions combined, the moral effect appeared at each processes (decentralization, re-engineering of human resources and industrial process technology), while the moral effect did not appear in (rebuilding organizational structures, improving total quality standards, and value engineering). This does not negate the importance of the impact of these dimensions, but rather shows a disparity between dimensions in reducing cost, when studying its combined effect. The study recommends that organizations should adopt modern management accounting methods, including value engineering, in order to identify and enhance activities that add value to the organization's operations, as well as identify and eliminate non-value adding activities, in order to reduce costs.

As a result of carrying out t-test against the learning activity that used the learning materials designed by level, significant disparity was found. Thus, it was found that hte effect of this learning activity became more visible with lapse of time. But the major cause by which there appeared small significant disparity as a result of testing is that the units of experiment were limited and that the period of using the learning materials was not long. In an analysis on the results of interest test, the experimental class also appeared to show the average score that was higher than that of the comparative class by 0.10 after converting a decimal point. The outcome of attitude test was that the experimental class showed a higher average score by 0.11, as a result of converting a decimal point, than that of the comparative class. So, a large number of students showed an improved reaction. But, there seemed some problems of the learning materials or the method of progressing the activity in changing under achievement students or students who avoided studying math. When the effect of the level-based learning activity was investigated, more than 80% of the experimental class’s students showed a positive reaction. Thus, it could be judged that students, who felt some burden at studying math, might be served more largely, not by teacher’s uniform instruction, but by an individual learning using the level-based learning materials that enabled them to do a systematic self-learning for themselves.

To study the effect of global warming on the growth of plants and plant populations throughout their life cycle under a field-like condition, we constructed a Temperature Gradient Chamber (TGC) in Tsukuba, Japan. The chamber had slender shape : 30 m long. 3 m wide, and 2.5 m high. That satisfactory performance was confirmed by a test throughout all seasons in 1998: the projected global warming condition in the near future was simulated. That is, independent of a great daily or seasonal change in ambient meteorological conditions, air temperatures at the air outlet were warmed 5$^{\circ}C$ higher than those at the ambient (the annual mean was 14.3$^{\circ}C$) with precision of ${\pm}$0.2$^{\circ}C$ (the annual means were 19.2$^{\circ}C$) with a rising rate of approximately 1$^{\circ}C$ every 5 m. This chamber will enable us to study the effects of global warming on growth of plants and plant populations because their abilities to control air temperature are excellent. TGC is expected that it would be utilized for studying the effect of global warming on plant growth under natural weather conditions.

본 연구는 고등학생의 학습탄력성에 관한 요인이 자기효능감과 학업성취감에 미치는 영향 요인은 스트레스 정도에 따라 조절효과가 있는지 분석해 보았다. 이를 위해 본 연구는 문헌연구를 통하여 인과모형과 연구가설을 설정한 다음, G광역시에 소재하고 있는 고등학생 292명을 대상으로 표본을 추출하여 설문조사를 실시하였다. 분석결과, 학습탄력성 요인인 인지능력과 의사소통이 자기효능감과 학업성취감에 미치는 영향은 스트레스 정도에 따라 차이가 있는 것으로 나타났다. 즉, 스트레스 정도가 낮은 고등학생일수록 자기효능감과 학업성취감이 높다는 점에 그 의의를 들 수 있다. 따라서 본 연구는 이러한 분석 결과를 토대로 학업성취감을 고취시킬 수 있는 방안을 제시하였다.

본 연구는 학생들의 수학을 공부하는 이유와 수학 교과목에 대한 평소 생각, 수학을 일상생활에 활용하는 응용 태도, 수학 교과서에 대한 학생들의 반응 등을 조사 분석하여 수학 공부를 해야 하는 이유를 바르게 인식시켜 수학 공부에 대한 동기를 높이고자 한다. 우리가 생활하고 있는 주변에서 수학적인 이론의 기본 지식들이 어떠한 방법으로 사용되고 있는지 실례를 들어서 분석하고 활용한다. 수학공부를 해야 하는 이유를 크게 세 가지로 나누어 첫째는 수학적인 지식을 통하여 삶의 지혜를 얻기 위한 학문으로서의 수학, 둘째는 실용능력배양을 위한 도구과목으로서의 수학, 셋째는 문화인으로서 갖춰야할 교양과 오락으로서 즐길 줄 아는 수학에 대한 쓰임새를 알게 하여 친생활적인 과목이 되도록 한다. 이런 과정의 결과로부터 효과적인 수학 교육 방안을 마련하여 보고자 한다.

Background and purpose: The purpose of this study is to review the recent achievements on ryodoraku and suggest new ryodoraku studies. Methods: The study papers related with ryodoraku, published in foreign countries and Korea up to the present, were collected first by internet search & journal. And then the collected papers were classified and summarized. Results and Conclusion: There are three study trends. One is finding some effect and analysis for some symptoms, another is finding a distinguishing mark and a diagnostic index, and the other is raising several points & providing solution & studying about relativity with another diagnosis. Some studies finding some effect and analysis for some symptoms are to be classified into four items(1. effect of drugs medication. 2. effect of ryodoraku therapy. 3. effect of other treatments. 4. effect of other treatments with ryodoraku therapy). Other studies finding a distinguishing mark and a diagnostic index are to be classified into two items(1. diagnostic index of symptoms. 2. distinguishing mark of disease). The other studies are to be classified into three items(1. ryodoraku introduction and raising several points at issue. 2. improvement machinery and tools. 3. studying about relativity with another diagnosis). Finally we need solving the ryodoraku problems(the condition of measurement and reproducibility, relation with Kyung-rak(經絡) and Ryodoraku, the reason of Ryodoraku points producing and etc.).

This paper presents a dynamic simulation algorithm for studying the effect of United Power Flow Controller(UPFC) on the low frequency power system oscillations and transient stability studies. The proposed algorithm is a Newton-type one and uses current injection type UPFC model, which gives a fast convergence characteristics. The algorithm is applied to studying inter-area power oscillation damping enhancement of a sample two-area power system both in time domain and frequency domain. The case study results show that the proposed algorithm is very efficient and UPFC is very effective and robust against operating point change.
