The recent development of information technology in general and consolidation of communications and multimedia technology in particular have brought enormous changes in education and training methods in many business organizations. Numerous studies in the education engineering field report that teaching using multimedia technologies will more enhance the education/training performance than the traditional instructor-teaching method. However, in the management information systems field, few studies are found which directly investigated effects of multimedia technologies on education and training. None of multimedia-related studies can be found in the top-ranked MIS journals published in Korea for the last five years, and only a few stuides are found even worldwide. The major steps of the current research are as follows. First, in order to identify important factors constituting the effectiveness of multimedia systems, previous research related to the effectiveness of multimedia systems was reviewed and analyzed. Second, individual items which can be considered as candidates to represent the effectiveness of multimedia systems were derived from this previous research review, and a survey questionnaire was developed using those derived items. Based on the developed survey questionnaire, a pretest was administered at several domestic business firms with experiences of multimedia systems. Third, survey questionnaires were distributed to and collected from the 517 employees which experienced using multimedia systems.

Recently, the development of sensor technology has led to an increase in research on unmanned aerial photogrammetry in various fields such as digital mapping, monitoring, cadastral survey, coastal survey, and topographic survey. However, existing studies are mainly limited experiments and analysis of specific application field, which is insufficient to demonstrate the validity of unmanned aerial photogrammetry for geospatial information construction. In this study, the studies related to the accuracy of unmanned aerial photogrammetry were investigated. The flight altitude and accuracy of horizontal direction is proportional to the GSD by analyzing the results of the individual studies conducted on the unmanned aerial photogrammetry within the last 5 years. In addition, the accuracy of the evaluation results varied widely according to the experimental conditions, and the problems of the previous studies that lacked the number of samples to evaluate the results were identified. A total accuracy analysis of 322 checkpoints yielded an accuracy of 0.028m in the horizontal direction and 0.044m in the vertical direction. In the future, the results of this study can be used as a basis for the validity of spatial information construction using unmanned aerial photogrammetry.

Facebook is very popular among young people and especially university students. Therefore, Facebook is the most logical platform to be used by academic libraries for promotional purposes and reaching out to user communities. This study aims to measure the effectiveness of using Facebook in connecting with students in academic libraries. A questionnaire survey was conducted to collect research data from students at four Vietnamese universities. A total of 1,670 valid questionnaires were returned, and more than half of the respondents were females between the ages of 18 and 22 years. The survey results found that libraries' Facebook pages did not receive adequate attention and interaction from students. Besides that, the information needs of students and social media content in general affected student acceptance of libraries' Facebook pages. These factors are demonstrated by the great majority of students who used Facebook often for various purposes, but fewer accessed library pages and they were not actively engaged in library posts. Students were interested in the information they already tended to get from libraries and were optimistic about the quality of library posts. However, they still expected more diverse and attractive content from the libraries. The findings of this study can help libraries create a close connection with students by satisfying their needs and expectations on Facebook.

The rapid rise in the application of novel treatment techniques, such as intensity-modulated radiotherapy (IMRT), motivated us to survey the status of Korea's radiation safety management and the shielding designs of facilities employing medical linear accelerators (LINACs). To this end, a questionnaire was used to collect information on LINAC facilities and treatments, workload, shielding design, shielding management, and path of obtaining shielding information. Out of 100 domestic institutions, 52 responded to the survey. Approximately 70% of the institutions utilized IMRT for more than 60% of their cases, and an IMRT factor of 5 was adopted by 75% of these institutions. Over 80% of the institutions accounted for the applied time-averaged dose rate per week and instantaneous dose equivalent rates in their shielding designs. Approximately 45% of the institutions obtained important shielding information via a radiation shielding design company and the NCRP-151 report. Overall, most facilities were shown to follow the standards recommended by the relevant international agencies. However, the requirement to establish standardized shielding design information and clarify ambiguous paths for information acquisition was also highlighted. Therefore, the study's results can be used as a foundation for establishing a safety control system and for creating adequate shielding designs.

This study attempted to grasp the current status of field training in the Department of Library and Information Science and the training institutions of the students of the Department of Library and Information Science and to propose a development plan based on this. To this end, a questionnaire survey and survey were conducted on the status of field practice in the Department of Library and Information Science at 4-year and 2-year colleges. As a result of the study, first, it was analyzed that field training has an effect on the employment competitive- ness and employment competency of students, and the field training environment has an effect on career decisions of students in the Department of Library and Information Science. Second, it was found that the library with the most field training was found to be a public library, and it was investigated that in order to allow students to experience various institutions and choose their career path, it was necessary to jointly discover and use field training institutes. Third, the evaluation contents or evaluators of the field training did not show a big difference by school, and it was found that most universities are evaluating the field practice using various scales. Lastly, in order to maintain the level of on-the-job training to some extent, it is necessary to develop a training manual and distribute it to each university.

As the hospital environment is changing rapidly, management is therefore obligated to use new ways to provide better service to patients. For example information system is introduced to some hospitals in Korea. Information system has several benefits such a soperational efficiency by on-line delivery and processing of data, accurate and rapid information production, continuous monitoring of performance and feedback, improvement of work process and better service quality. Still, many hospitals cannot be sure that information system is useful for improving organization performance. Because only one or two area of hospital information system were considered for development and with limited development hospital information system cannot be used effectively. The purpose of this study is to suggest the model of information system utilizaton and to analyze the hospital in formation system in Korea. The results are following; 1. In Korea, proportion of operating system of comuter is 31% of UNIX, 11% of IBM OS and 10% of PC LAN. 2. As we expect, scope of application software and amounts of heardware and software invest ments are affected by concern of CEO. 3. Many CIO(chief information officer) say that the biggest problems are lack of after-service and obsolescence of computer equipments in terms of hardware and shortage of application software for hospital in terms of software. 4. Personnel of information system department is so small that hospital information system can't be improved. 5. During the development of information system, full-time participation of end user is only 20% hospital with almost less than 12 person-month. This study was accomplished by survey through mail questionnaires. Response to the survey was only 55% and it was hard to generalize all the result obtained from this survey. However, We hope that this study would be helpful for helth care organization to acknowlege hospital information system in korea and to design the future architecture and frame of information system.

현재 공시지가를 산정하기 위하여 매년 현장조사방법으로 수집되는 지형 지세자료의 정확도를 인정할 수 없다는 지적이 많지만, 이에 대한 구체적 연구는 없는 실정이다. 본 연구는 현장조사방법으로 지방자치단체가 수집한 지형 지세자료의 정확도 분석을 위하여 수치표고모델로 분석한 자료와 부합여부를 조사하였다. 분석결과, 총 1537 필지 중 324 필지가 불부합하여, 불부합 비율은 17.36%이다. 11개 연구지역 중 부불합 비율이 20%이상인 지역은 5개이고, 가장 심함 지역의 불부합비율은 38.71%로 나타났다. 대체로 고도가 높고, 경사가 불규칙하여 지형 지세가 복잡한 지역은 불부합 비율이 높은 반면, 지형 지세가 순탄한 평야지역은 불부합 비율이 낮다. 이상 분석결과는 현장조사방법으로 지형 지세를 조사하는데 한계가 있음을 시사한다. 따라서 우리나라 국토가 고도와 경사가 불규칙한 매우 복잡한 지형 지세임을 고려할 때, 공시지가제도에서 토지의 지형 지세를 정확하고 효과적으로 조사하기 위해서는 먼저 법률적 기준을 정량화하고, 기존의 현장조사 방법을 공간정보 분석방법으로 전환해야 한다.

사회지표조사는 주민들이 생각하는 사회 상태를 총체적으로 파악할 수 있는 조사로서 다양한 시책 개발에 있어 지역의 여론을 반영할 수 있는 장점이 있다. 사회지표조사는 사회 변화를 알 수 있는 중요한 척도라고 할 수 있으며, 많은 지자체 (서울시, 인천시, 부산시, 울산시, 경상남도 등)에서 많은 예산과 시간을 들여 조사를 실시하고 있다. 그러나 조사에 대한 분석 결과가 기초통계분석 위주로 되어 있어 실제 사회지표조사 자료를 제대로 활용하고 있지 못하고 있는 실정이므로 데이터마이닝 등의 다양한 방법의 적용이 필요하다. 이에 본 논문에서는 사회지표조사의 효율적인 분석을 위하여 새로운 데이터마이닝 방법론을 제시하고자 한다. 본 논문에서는 매개연관성규칙, k-평균 군집분석, 의사결정나무를 순차적으로 적용하는 3단계 복합 데이터마이닝의 적용 방법을 제안하며, 이를 2010년에 조사된 경상남도 사회지표조사 자료에 적용하고자 한다.
