This study examined research data management practices from the perspectives of university researchers. A survey was conducted for principal investigators of projects in universities selected to be funded by National Research Foundation in 2010 and 2011. Predicated on the analysis of 131 survey responses, there was a great difference in types of research data between Humanities & Social Science fields and Science, Medicine and Engineering fields. Most respondents added value of their data by linking to other types of information or combining data from other sources. For storing data, PC or portable media were generally employed, and around 80% of respondents saw their data having a useful life under 10 years. Data was shared within research team and with outside researchers who requested data. The percentage of respondents who have reused data was higher than that of respondents who have shared data. In order to obtain data for reuse, the majority of respondents drew data from published articles, or contacted data creators. In most cases, mechanisms for managing data did not exist in projects or universities where respondents belong. Since the level of satisfaction with long-term preservation and metadata description of research data was found to be low, it was necessary to develop data archiving services to support the data management procedures.

Although noise-induced hearing loss (NIHL) is a significant public health problem, many people might not be aware that exposure to loud noise could occur hearing loss. The purpose of this study is to evaluate and analyze how importantly and seriously people are aware of NIHL using a 22-question survey. It was administered to random 150 people including between 20 s to 60 s. The questionnaire contained questions about i) views toward general health issues including hearing loss and tinnitus, ii) noise exposure, and iii) views toward hearing protection. Results showed that hearing loss was defined on a likert scale as 'a very big problem' by 17.33 % of respondents compared with other health issues. Surprisingly, most respondents (82 %) had not heard, read, or seen anything lately related to the issue of hearing loss. Many respondents had experience hearing problem or tinnitus under loud noise situations (85 %), however, only 11.33 % of respondents had used earplugs. Fortunately, many could be motivated to try ear protection if they were advised by a medical professional (80 %) or were aware of the potential for permeant hearing loss (78.67 %). We concluded that awareness of the potential for permanent hearing loss with noise and effective methods of hearing protection should be announced to public for preventing NIHL.

At a time of growing importance of safety management in the social welfare facility by the increase of social welfare facilities, this study analysed safety perceptions about facility management, facility conditions, and facility structure and arrangement. This study sample consisted of 204 service providers and service users in 12 social welfare facilities. T-test and ANOVA were used to find the group differences among facility types. The findings were as follows. Firstly, safety perceptions of the service providers were significantly higher than those of service users in terms of facility management, and facility structure and arrangement. Secondly, in terms of facility types, the respondents in the family service center had lower safety perceptions than the respondents in other service in all three areas. Thirdly, facilities that are of 10 years or older had higher safety perceptions than the respondents of facilities that are 6 to 10 years old in the area of facility management, and facility structure and arrangement. Fourthly, in regard to building heights, the respondents in 3 to 4 story facilities had statistically higher safety perceptions than respondents in 1 story facilities. Finally, looking at the relationship between floor area and safety perceptions, safety perceptions of the respondents of less than $400m^2$ facilities or $600m^2$ and more facilities were significantly higher than those of $400m^2{\sim}$ less than $600m^2$ facilities.

As services requesting data transfer from a sender to a multiple number of receivers become popular, efficient group communication mechanisms like multicast get much attention. Since multicast is more efficient than unicast in terms of bandwidth usage and group management for group communication, many multicast protocols providing scalability and reliability have been proposed. Recently, router-supported reliable multicast protocols have been proposed because routers have the knowledge of the physical multicast tree structure and, in this scheme, repliers which retransmit lost packets are selected by routers. Repliers are selected dynamically based on the network situation, therefore, any receiver within a multicast group can become a replier Hence, all receivers within a group maintains a buffer for loss recovery within which received packets are stored. It is an overhead for all group receivers to store unnecessary packets. Therefore, in this paper, we propose a new scheme which reduces resource usage by discarding packets unnecessary for loss recovery from the receiver buffer. Our scheme performs the replier selection and the loss recovery of lost packets based on the LSM [1] model, and discards unnecessary packets determined by ACKs from erasers which represent local groups.

A two-year survey of consumers'awareness and perception of genetically-modified (GM) foods was conducted during May through September of 2000 and 2001 with a random sample of Korean consumers. More than 68% of the respondents were exposed to some information related to GM foods. The greatest benefit of the development of GM foods was thought to be the remedy for the food shortage in the future. More than 90% of Korean consumers wanted GM foods to be labeled. About 18% of the respondents would buy GM foods voluntarily, whereas over 49% would not until they found out more. Only 40% of Korean consumers were found to realize that food items originated ken plants contain genes. More consumers responded that they would not buy herbicide-tolerant GM soybean but buy vitamin-enriched GM soybean. It seemed to be that many Korean consumers do not make decisions of acceptance or rejection of GM foods not on the basis of biotechnology but on the basis of the word(5) used to describe the products, such as herbicide and vitamin. Only 4% of Korean consumers responded that GM foods were the greatest safety-threatening factor of Korean foods.

본 연구에서는 수자원 통합모델링 프레임웍을 개발하기 위하여 국내의 모델개발과 프로그램개발 환경에 대한 사용자 요구조사를 실시하였다. 요구조사의 응답자는 총 19명 이었으며, 그 응답자는 대부분 수자원의 지속적 확보기술개발 사업에 참여하고 있는 연구자를 대상으로 하였다. 사용자 요구조사 결과 국내에서는 물관련 전공자들이 모델과 프로그램의 개발을 동시에 수행하는 경우가 많았으며, 대부분 Fortran을 중심으로 다양한 프로그래밍 언어를 사용하고 있었다. 모델개발자들은 모델간의 연계에 대한 필요성은 느끼면서도 모델간의 연계에 대한 실제적인 구현도구를 찾지 못하고 있으며, 모델의 공유에 대한 인식도 낮았다. 따라서 향후 통합모델링 프레임웍의 구체적인 설계 단계에서는 모델개발자가 개발된 모델의 프로그램으로 쉽게 구현할 수 있도록 편리한 사용환경이 요구되며, 모델간의 연계를 위한 프로그램 표준화작업도 동시에 수행되어야 할 것으로 판단된다. 또한 통합모델링 프레임웍의 설계에 있어 사용자의 요구를 충분히 반영하기 위하여 사용자 요구조사를 바탕으로한 통합모델링 프레임웍 개발 가이드라인을 제시하였다.

본 연구는 시간자원의 중요성이 증가하는 현대사회에서 주부가 지각하는 시간압박 감이 점차 높아질것으로 예상되는 가운데 시간압박감이 소비자행동에 어떻게 작용하고 그로 인한 문제점은 무엇인지 밝혀보려는 의도에서 수행되었다. 서울시에 거주하는 주부 546명을 대상으로 시간압박지각정도를 측정하고 이를 바탕으로 소비자집단을 분류된 소비자 집단 사이에 인구.사회 경제적특성과 시간 절약형 내구제의 구매의사결정 과정의 차이가 있는지 분석하였다. 그 결과 시간 압박지각 정도에 따라 고.중.저의 세집단으로 구분되었는데 중간집단에 가장 많은 응답자가 포함되었고 높게 지각하는 집단에 가장 적은 응답자가 포함되었다. 그러나 기존의 연구와는 달리 취업주부의 18.7%가 시간압박을 낮게 지각하는 집단에, 그리고 전업주부의 6.8%가 시간압박을 높게 지각하는 집단에 분류되어 취업주부가 시간압박을 높게 지각하는 전형적인 소비자집단이 아닐수 있음을 발견하였다. 집단별 인구.사회경제적 특성과 시간절약형내구재의 구매의사결정과정의 차이도 부분적으로 밝혀졌으나, 예상과 달리 시간압박감을 높게 지각하는 집단의 시간절약형내구재의 소유와 사용이 오히려 낮게 나타났다.
