This study was designed to analyze the differences in science achievement and satisfaction between the environments of Face-To-Face (FTF) and Computer Mediated Communication (CMC), and between the interactions of Teacher-Students (TS) and Students-Students (SS). The activities for the interaction in the FTF and the CMC were carried out in the environments of traditional classrooms and the on-line network of communication computer, respectively. These experiments for four different groups (CMC-TS, CMC-SS, FTF-TS and FTF-SS) were performed with respect to 103 students of three 10th grade classes at a girls' high school in Chungju city. The questionnaires were composed of 5questions for achievement, and 13 questions on Likert scale for satisfaction. The data was analyzed using ANOVA, and through examination of each question about the satisfaction. The mean of the science achievement in learning activity was significantly higher in the CMC environment than the FTF. Also, the score in the TS interaction was meaningfully higher than the SS. Under the common environment of the CMC, science achievement and satisfaction in the TS interaction were significantly higher than in the SS. A similar result has been obtained in the satisfaction case even in the common environment of the FTF. The itemized analysis for the satisfaction shows a high score in the individual condition of CMC and TS, compared to that of FTF and SS, respectively. Thus, the school activity, formed in the TS interaction in the CMC environment is more effective at improving science achievement and satisfaction in the teaching and learning of science.

본 연구에서는 국가의 연구개발활동조사에서 기업연구개발활동 통계에 대한 효과적인 산출방법을 제시하고자 하였다. 이를 위하여 국내 외 연구개발 통계방법을 조사한 후 이를 토대로 우리나라에서 기업연구개발활동에 대한 자료의 수집 및 분석에 대한 개선방안을 제시하였다. 대부분의 국가에서는 대기업은 전수조사, 소규모 기업은 표본조사를 수행하고 있으나, 우리나라에서는 연구소 등록법인에 대하여 전수조사를 행하고 있다. 전수조사는 비용이 많이 들고 비 표본오차로 인하여 모집단에 대한 체계적인 추정이 불가능하다는 문제점이 있다. 현재 산업기술진흥협회에 등록된 연구기관의 수가 20,000개를 넘어서고 있어 전수조사는 한계에 다다른 것으로 생각되어 표본조사 도입에 대한 타당성과 방법론을 중점적으로 검토하였다. 먼저, 표본조사의 타당성을 평가하기 위하여 현재 전수조사를 통해 수집된 자료를 이용하여 표본조사를 수행한 결과를 비교 분석하였다. 산업별(24개), 그룹별(8개)로 구분하여 216개 셀별로 모집단수/표본수를 곱하여 산정 (셀별추정법)한 결과, 전수 통계치와 거의 동일하게 나타났다. 따라서, 산업별, 그룹별로 세분하여 모집단수/표본수를 곱하여 추정하는 셀별추정법이 타당한 것으로 평가할 수 있다. 이상의 분석결과를 토대로 새로운 조사설계방안을 제시하면 다음과 같다. 직전연도 조사기업은 직전연도 연구개발비 수준과 기업종류(대기업, 벤처기업, 중소기업), 그리고 산업에 따라 셀을 분할한다. 대기업, 연구개발비 수준이 높은 기업 등 주요한 셀에 대하여는 전수조사를 실시한다. 나머지 셀에 대하여는 각 셀별 연구개발지출의 분포가 동질적이기 때문에 표본 추출방법은 단순임의추출법(SRS)을 사용한다. 다만 전년도 미계상된(또는 미포함된) 기업에 대하여는 신규 대형 연구소 진입 등을 고려하여 규모비례확률추출법(PPS)을 고려하는 것이 바람직할 것으로 판단된다. 일부 기업들이 특정 항목에 대한 자료를 제공하지 않는 항목무응답의 경우, 누락된 자료에 대하여는 대체기법(Imputation Algorithm)에 따라 이를 추정한다. 이러한 표본조사방법은 전수조사에서 발생하는 비 표본오차를 해소하고, 자료수집비용 및 소규모기업의 행정적 부담을 경감할 수 있다는 장점이 있다. 향후 연구에서는 좀 더 구체적인 조사방법론을 강구할 필요가 있으며, 이와 함께, 연구개발에 대한 다양한 측면의 정보를 수집하기 위해 새로운 설문지를 개발할 필요성이 있다.

The purpose of this study is to find a model that can measure the public relations programs based on the assumption that the public relations should aim to lift the corporate reputation. It is a trend that corporate's activities are to be measured from the standpoint of cost-benefit efficiency. However, public relations fields in Korea is left behind this trend because the fields lack in sophisticated model. In order to fill this gap, the researchers introduce the reputation measurement model that can calculate individual corporate public relations programs. In addition, this reputation model Is applied to Korean companies with the expectation of producing a PR index which ran be used to measure the reputation as corporate asset, or superbrand. This study examines the effects of superbrand on consumers according to the media use. Based on the expert group interviews and surveys on consumers, the factors of reputation are drawn. These factors contribute to find reputation model and measurement index which are again applied to measure the Korean companies' public relations programs. Using superbrand as dependent variables and managing abilities, corporate responsibility, corporate communication, and product/employee quality, this study seeks to find which factor specifically attribute to lift corporate reputation. Results show that each factor influences the corporate reputation positively. In addition, the researchers find that media use is moderately related to the superbrand building process in cognitive dimension.

This study was designed to suggest the effective CSR strategies for MNCs operating in Chinese market. For this purpose, it compares the multi-years results for the evaluation on CSR activities of Multinational and Chinese firms. It also conducts questionnaire survey in an attempt at developing measures of Chinese publics' perception on the four dimensions of CSR defined by Research Center of Chinese Academy of Social Sciences - responsibility management, economic responsibility, social responsibility, and environmental responsibility. The findings of empirical analyses indicate that the CSR activities of MNCs much fall in all four dimensions compared with them of Chinese firms. Among four dimensions, MNCs have had bad evaluations especially on economic responsibility and social responsibility that are considered more important than the others to Chinese. Those findings imply that the MNCs has so far failed to implement effective CSR activities in China. In order to offset their liabilities of foreignness and compensate for their disadvantages in the lack of governmental supports, MNCs should intensify the CSR in economic and social responsibilities.

In the police, crime intelligence is the basis of decision making for police's original activities in response to crime. Police decision making is done in various ways such as investigation and prevention of individual cases, allocation of resources, organization prioritization, etc. The purpose of this study was to investigate the activities of the UK policing in analyzing crime intelligence and to reflect them in the policing and to draw implications for the comparison with the Korean police. The UK operates a central police agency based on the local police system, and establishes a National Intelligence Model (NIM) system that operates crime intelligence throughout the country. In order to respond to crimes and risks through coordination and cooperation, rather than by centralized police activities, the intelligence department of the police agencies should not only prevent and suppress crime through the analysis of integrated crime information, but also make police decision-making. In contrast, the Korea police operate crime intelligence, such as statistics, case intelligence, and there is no integrated way to use it. In addition, there are few cases in which the organizational decision - making based on crime intelligence is utilized efficiently and systematically. For development, it is necessary to construct an integrated management system and analysis organization for crime intellgence. Criminal Intelligence Analysis Organizations should seek to reorganize the role of the current intelligence department or to operate a separate analysis system through the information system while maintaining the current role of each department.

In this study. 'extended science investigation' was conceptualized as a comprehensive science investigation contrasted with exercise of process and skill component and cookbook style experiment. The extended investigations should be pursued for giving opportunity of more authentic science activities in school science. And one of important educational objectives in students' science investigations is to achieve motivation for investigation which drives and triggers further investigations. It can be discerned as positive and negative by its direction and also as internal and external by its cause. The purpose of this study was to describe change of students' motivation for investigation while they were performing the extended science investigations. The subject was 128 7th grader attending coeducational school in Seoul. Questionnaires and students' reports were analysed complementarily to describe students' motivation for investigation. The number of students who showed positive motivation for investigation did not increase in the developed extended investigations than in the directive investigations in textbook, but the cause of positive motivation for investigation has changed largely from task-exclusive factors to task-inclusive factors. In case of negative motivation for investigation, regardless of the kind of investigation task, task-inclusive factors were recognized as the main causes. Among those whose motivation changed during successive extended investigations, the students who showed change from negative to positive were more than the reverse. And the number of positive intrinsic motivation for investigation was increased at the second half of the extended science investigations. So it can be said that there was a desirable change of motivation for investigation at the second half the extended science investigations.
