The Public Service Charter is one of the administrative reform programs introduced to promote customer oriented administration. It's main purpose is to achieve citizens' confidence in the government by satisfying them with elevated quality of the public services. This study focuses on analyzing current conditions and achievements of the Public Service Charter in the Republic of Korea and proposing it's development plan. Since it was introduced to Korea in 1998, the Public Service Charter has been disseminated and contributed to the spreading of the citizens' understandings of the government's initiatives for customer satisfaction plans. Still, it has several problems as follows; A lot of public servants and citizens lack in understandings of this program. CEOs don't have enough concern in it. Evaluation is not organically connected to performance management. The correction and compensation procedure are not well operated. To solve these problems, the government needs to set up an institutional foundation establishing a legal base, uplifting CFO' concerns, and building a department with full responsibility, and to promote employees and citizens' participation through education and PR. It's also important to enhance post management by efficient evaluation and performance management, substantial correction and compensation procedure.

This paper reports on the main results of 3 study that compared students' beliefs, skills, and understandings in an innovative approach to differential equations to more conventional approaches. The innovative approach, referred to as the Realistic Mathematics Education Based Differential Equations (IODE) project, capitalizes on advances within the discipline of mathematics and on advances within the discipline of mathematics education, both at the K-12 and tertiary levels. Given the integrated leveraging of developments both within mathematics and mathematics education, the IODE project is paradigmatic of an approach to innovation in undergraduate mathematics, potentially sewing as a model for other undergraduate course reforms. The effect of the IODE projection maintaining desirable mathematical views and in developing students' skills and relational understandings as judged by the three assessment instruments was largely positive. These findings support our conjecture that, when coupled with careful attention to developments within mathematics itself, theoretical advances that initially grew out research in elementary school classrooms can be profitably leveraged and adapted to the university setting. As such, our work in differential equations may serve as a model for others interested in exploring the prospects and possibilities of improving undergraduate mathematics education in ways that connect with innovations at the K-12 level

영상기억은 시각기억 처리 과정의 최초 저장 기제로서 오랫동안 이론적인 타당성을 인정받아왔다. 그러나 최근 관심이 대폭 증가한 시각단기기억과 시각장기기억에 비해 영상기억에 대한 연구자들의 관심은 상대적으로 부족했던 것이 사실이다. 이러한 관심의 부족은 영상기억 및 시각지속 현상에 대한 이론 및 방법론적 이해의 결여가 그 원인인 것으로 짐작된다. 본 연구는 영상기억 및 시각지속 현상에 대한 이론적 배경과 경험적 연구 사례를 개관해 영상기억에 대한 상세한 이해를 도모하였다. 더 나아가 영상기억의 타당성에 대한 현상학적, 생태학적 비판들의 핵심 내용들을 토대로 향후 영상기억 연구의 방향을 가늠하는데 목적을 두었다.

The purpose of this study is to investigate college science students' and science teachers' understanding of chromosomal behavior in the context of cell division. The research problems were as follows: 1. What is the level of college science students' understandings of chromosomal behaviors? 2. What is the level of science teachers' understandings of chromosomal behaviors? 3. What is the level of understanding by grade and major area? The sample consisted of 28 sophomore, 17 junior and 23 senior biology students; and 23 middle school science teachers and 14 high school biology teachers. The instrument of the study was a short answer required paper and pencil test. The results of the study were as follows: 1) About 15 percent of the sample could not count the number of chromosome in a cell in appropriate. 2) Seventy percent of the students, and 80 percent of the teachers identified homologous chromosomes as ones with the similar shape and size, and 30 percent of the whole sample could not pair two homologous chromosomes. 3) About 70 percent of the students and 30 percent of the teachers could not mark corresponding allele on chromosome. 4) Biology major students showed higher understanding of overall chromosomal behaviors than non Biology students. Based upon the results, some implications were made. The major one was a development of a teaching model in which students can improve the ability to connect chromosome theory to mendelian genetics.

Pressure pulsation Inside the discharge and suction cavity of rotary and scroll compressor are often a major source of objectionable noise and vibration. The key factor of these noise and vibration is due to the cavity resonance. It is not only necessary to understanding the characteristics of pulsation in order to reduce the excitation force of gas to the cavity but also to verifying the phenomena of cavity resonance. For the purpose of these understandings, measurement and simulation of cavity resonance can lead to a better understandings how they occur and be very important to identify the ways to reduce the noise efficiently. In this paper, modeling of the cavity(internal acoustics inside the shell) is discussed and simulated using FEM. Results from the simulation are compared with those measurement in experiments. In describing of cavity mode by experiments, it is very important to specify the exact conditions under which they are measured. Finally, this paper shows the one example of reduced cavity resonance in the compressor.

The purpose of this study was to investigate beginning elementary teachers' beliefs about the nature of science. Defining teachers' beliefs as a broad construct, we tried to examine the teachers' understandings about the nature of science. The methodology of this study was a qualitative approach through semi-structured interviews. In an urban area of Korea, five beginning elementary teachers were chosen. The cross-case and grounded theory study design were adopted for the data analysis. The results of data analysis were checked by teachers for internal validity. This study identified the teachers' beliefs about the nature of science suggested by many researchers. The results of this study showed that: 1) beginning elementary teachers did not well understand and were unfamiliar with the meanings of various terms about the nature of science; 2) their beliefs abut the nature of science were broad and various; 3) they understood some parts of the nature of science; 4) there were differences within their understandings about subconcepts of the nature of science.
