Recently, there have been a number of news reports on natural disasters, like earthquakes. typhoons, floods and tsunami, all over the world. Korea does not seem to be safe from such disasters or terror threats. As places with high numbers of visitors. libraries need to take preventive measures to be prepared for such disasters and threats. This paper analyzes the current status of emergency measures adopted by 75 public libraries in Seoul. Daejeon and Jeonbuk in Korea. For each library surveyed. the causes of and ways to recover from disasters were reviewed and detailed analyses were carried out in low areas: Implementation of preventive measures disaster management and equipment, status of human resources and assignment of people to disaster recovery, safety courses offered to library users and training methods. In addition, each area was analyzed in regard to possible solutions and ideas for improvement, as well as suggestions to upgrade disaster recovery systems in the future.

They have been indicating that they cannot make their new employees to be committed immediately to working and suggesting the need for development of the program for improving the undergraduate students' practical ability in the business of architectural engineering. Specifically, in case of local colleges and universities, it is relatively difficult to establish the relationship with local industries or institutes and get a chance to visit various construction sites and meet with experienced professionals. In this study, a new course in the business of architectural engineering is developed for improving the undergraduate students' practical ability. In addition, the class website is developed to provide multimedia educational materials for distance education. Surveys on the programs and course materials developed through this research study will be conducted periodically to improve them continuously. It will encourage their sustainable use.

In order to manage the lectures efficiently in the university and improve the educational outcome, the process is needed that make diagnosis of the present educational outcome of each classes on a lecture and find factors of educational outcome. In most studies for finding the factors of the efficient lecture, statistical methods such as association analysis, regression analysis are used usually, and recently decision tree analysis is employed, too. The decision tree analysis have the merits that is easy to understand a result model, and to be easy to apply for the decision making, but have the weaknesses that is not strong for characteristic of input data such as multicollinearity. This paper indicates the weaknesses of decision tree analysis, and suggests the experimental solution using multiple decision tree algorithm to supplement these problems. The experimental result shows that the suggested method is more effective in finding the reliable factors of the educational outcome.

일반적으로 알려져 있는 소에 있어서의 제각은 화학적인 소락제, 송아지 제각기 (tube calf dehorner), 전기인두, 톱 및 선거(線鋸; wire saw) 등을 이용하고 있으나, 제각 처치시 소에 많은 스트레스를 주고 있는 실정에 있다. 2001년도에 일본의 요우카이치시(四日市) 소재 냉동 및 냉장창고업을 하는 일신냉장고(주)에 근무하는 직원이 현내의 비육농장에서 제각하는 것을 보고, 생산자나 소비자로부터 이야기를 나누던 중, 점차적으로 소 사육농장에서 다두사육화가 되면서 우군 무리중에서 순위싸움으로 인해 외상을 입거나, 경쟁에 밀린 소는 사료를 제대로 먹지 못하여 스트레스를 받는 다는 것에 착안하여, 끝이 뾰쪽한 뿔에 복싱 글러브(boxing glove)와 같은 커버를 장착하면 제각을 하지 않고 소 본래의 자연체형을 유지한 체로 안심, 안전, 위험방지가 가능한 소의 뿔 커버를 연구개발하게 되었다. 최초로 제작된 소의 뿔 커버는 고무 특유의 수축작용을 이용해서 소의 뿔에 장착하였으나, 소의 큰 압력에 눌려 하루도 못가 각상피(角上皮)와 같이 탈락하였으며, 그 후 약 3년간은 실패를 거듭한 끝에 4년째인 2005년 봄에 의외의 장소에서 힌트를 얻었는 데, 귀가시 가족중 우연히 이가 빠졌는 것을 보고, 소의 각돌기(角突起)의 각첨부(角尖部)에 고정하는 방법을 생각하게 되었다. 연구를 시작하면서부터 NOSAI 수의사들, JA 동일본조합사료 수의사, 전농축산 서비스 등의 도움을 받았으며, 이후 오리온기업육성기술개발지원사업에 채택되어 4년여간의 연구를 한 끝에 약 30초의 부착시간이 걸리는 1회성의 영구적인 소의 뿔 커버를 특허개발(2005년)하여 2008년도부터 판매하기 시작하여 거세 화우, 교잡종 화우암소, 화우 암소 등에 일본 전역에서 보급되어 시술되고 있다. 최근 수개월전에 제가 아는 지인이 일본서 뿔 커버 2두분을 직접 구입하여 왔는 바, 직접 한우 경산우 암소 2두에 극히 간편하고 쉽게 시술하였기에 소개하여 도움을 주고 저 한다.

The purpose of this study is to identify contradictions in library internship, and address them. As a case study, students who were enrolled in the internship class opened in the 2016 fall semester in a university in Seoul were interviewed. Through applying Activity Theory, the process of internship and contradictions presented in its process were analyzed. The findings indicate that students were satisfied with their internship experience. The internship experience also makes positive impacts on students in terms of understanding the library and information science and deciding their future career as a librarian. Such contradictions as internship duration, operation of the internship process, level of participation or practice, and overlap of part-time experience in a library were identified. This study suggests to make the internship systematic in order to address the contradictions through that all parties in internship are actively participated in internship and that they share information related with the internship.

In this paper, we introduce a modified Moore Method designed for the multivariable calculus course, and discuss about the effective teaching and learning method by observing the changes in the understanding of students' learning and the effects on students' learning in the class implemented by this modified Moore Method. This teaching experiment research was conducted with the 15 students who took the multivariable calculus course offered as a 3 week summer session in 2008 at H University. To guide the students' active preparation, stepwise course materials structured in the form of questions on the important mathematical notions were provided to the students in advance. We observed the process of the students' small-group collaborative learning activities and their presentations in the class, and analysed the students' class journals collected at the end of every lecture and the survey carried out at the end of the course. The analysis of these results show that the students have come to recognize that a deeper understanding of the subjects are possible through their active process of search and discovery, and the discussion among the peers and teaching each other allowed a variety of learning experiences and reflective thinking.

We propose a low cost attendance checking system using NFC (Near Field Communication) and show a case study of an actual operation of the system in a higher education institute. The system offers a direct attendance check service when a student touches NFC tag on a classroom desk with his/her own smartphone. Our service was first developed and operated in 2012, and then additional functions like massive real time processing were reinforced. In the fall semester, 58 courses use the service and 96% of the class attendance was checked with mobile devices. The only hardware requirement of the system was NFC tag on the classroom desk, which reduced hardware cost dramatically. However, it also minimized attendance checking time into 1 minute regardless of enrolled student number.

The purpose of this paper is to study of the attitude of e-learning on the effectiveness of e-learning and the antecedents of e-learning. For this study, samples were collected from students who had attended a cyber lecture at university. Structural equation model was used to analyze the data. The result of this empirical study is summarized as followings. First, the attitude of e-learning has a positive effect on the e-learning effectiveness. Second, ease of use of learning management system, learning motivation, information quality of learning contents has positive effect on the attitude of e-learning, but usefulness of learning management system has no effect on the attitude of e-learning. Therefore, the former consists of learning management system, learning contents and information quality that are provided by e-learning and the latter means learning motivation.

This study was designed to analyze the difference in attendance and academic achievement based on spatio-temporal data relate to e-Learning patterns of university e-Learning learners. This study collected e-Learning data from 68 e-Learning classes, 13,611 learners during 3 years. Collected data were analyzed by t-test and two-way ANOVA. Major study findings were as follows. Firstly, e-Learning learners in school received higher than those of learners outside school both in attendance and academic achievement, while that academic achievement showed statistical significance. Secondly, the attendance and academic achievement by the day was in the order of e-Learning learners mainly in the morning, those in the afternoon and those at night, in addition there was statistical significance. Lastly e-Learning learners in the weekdays appeared higher than those of learners in the weekends both in attendance and academic achievement, also both of them showed statistical significance.
