Objective: Meditation can elicit trait-like changes in psychological and social styles, as well as enhancement of emotional regulatory capacity. We investigated the relation between personality traits and emotional intelligence in meditation practitioners. Methods: Seventy-two long-term practitioners of mind-body training (MBT) and 62 healthy comparative individuals participated in the study. The participants completed emotional intelligence questionnaires and the Myers-Briggs Type Indicator (MBTI). Results: The MBT group revealed higher scores on all five emotional intelligence factors than did those in the control group, such as emotional awareness and expression, empathy, emotional thinking, emotional application, and emotional regulation (all $p{\leq}0.001$). MBT practitioners also had higher scores on the intuition of perceiving function (t=-2.635, p=0.010) and on the feeling of the judging function (t=-3.340, p=0.001) of the MBTI compared with those in the control group. Only the MBT group showed a robust relationship with every factor of emotional intelligence and MBTI-defined intuitive styles, indicating that higher scores of emotional intelligence were related to higher scores for intuition. Conclusion: Emotional intelligence of meditation practitioners showed notable relationships with some features of personality trait. In-depth associations between emotional intelligence and personality traits would help to foster psychological functions in meditation practitioners.

This paper illustrates key features of an enterprise employment simulation which integrates a system dynamic feedback model with a cost-effectiveness optimisation capability utilising genetic algorithms. Its core is a 3-dimensional array structure tracking staff numbers by rank, by time-in-rank, by years-of-service. The resultant model, which could readily be adapted to non-Defence use, can identify, given user specification of any mix of employment rules, the likely patterns of employment behaviour including: resultant time-in-rank and years-of-service profiles; ability of a Unit to fill all positions to target strength; ability to fill promotional positions within normal rules for substantive promotion; need to fill promotional positions using rules for temporary promotion or transfer from outside; necessary recruitment pattern to sustain target strength.

Objectives: In order to provide basic data for future researchers, this study aims to explore future tasks after reviewing the changes in port safety management due to the enforcement of the Special Act on Port Safety. Methods: The provisions of the Special Act on Port Safety were analyzed and the latest literature related to port safety management was reviewed. Results: There are two major changes that have stemmed from the Special Act on Port Safety: 1. The scope of application for port participants has been expanded, safety education has been made compulsory, and safety management plans have been established and implemented for each business site. 2. The government is operating a port safety consultative body for each port and has hired one port safety inspector for each of the eleven local maritime and fisheries offices across the country. Future tasks include elaboration of port safety accident statistics, strengthening shipping companies' responsibility for stevedore safety, the unification of contracts, and government interest and support for port safety facilities. Conclusions: The primary feature of the Special Act on Port Safety is the emphasis on autonomous safety management by participants in port transportation. In addition, the enactment of the special law has allowed the Ministry of Maritime Affairs and Fisheries to actively intervene in port loading and unloading safety.

This qualitative study investigated different interaction patterns in an online discussion. The data was collected from asynchronous discussion occurred in a graduate course. The data analysis methods include inductive analysis and mapping strategy. The results of the study suggest three layers of interaction: response sequences, interaction amongst participants, and concept map of messages. The visualization of response sequences enabled the researcher to discover complex and dynamic interaction patterns amongst participants. The many-to-many communication feature of online discussion does not always enable direct one-on-one interaction between two participants. Rather, one message contributed to multiple threads in the stream of conversation. In terms of interaction amongst participants, the interaction amongst participants, as indicated in the data, the messages also bind each participant and consequently a group(s) of participants together. It appears that the contribution of one message may not only enable a response to one participant, but also connect many participants to each other. The concept map of messages proposes that response sequences and interaction amongst participants can also be viewed between concepts within messages in the discussion. On the surface, the messages posted by individuals are linked by the system in a linear fashion as they are posted. However, the interaction extends to collaborative conversation amongst participants. Ultimately, a conceptual network of interrelated ideas including multiple perspectives is built in asynchronous discussion.

The purpose of this study was to identify differences in teachers perception on educational attributes and effectiveness of IPTV according to demographic factors. To investigate possibility of educational application, the participants of the study were teachers selected from IPTV initiative schools in elementary and middle levels nationwide. 55 teachers participated from 22 IPTV model schools nationwide, which were 9 elementary schools, 6 middle schools, 7 high schools. As results of research, there were some significant foundings. In terms of the perception on educational attributes of IPTV, there are explicit perceptional difference between "capital area teachers" and "the other regional teachers". However, there were no significant difference according to school level. Perception of male teachers were more positive than those of female teachers. Also, there were no significant difference according to teaching experience. On the other hand, in terms of the perception on educational effects of IPTV, we could conclude that teachers from metropolitan cities have more negative perception on IPTV than teachers from other kinds of cities have. Regardless of school levels, teachers showed merely fair perception on effectiveness of IPTV. There was significant difference between male teachers and female teachers in perception on educational effectiveness. Also, Results showed no significant differences according to teaching experiences. Future tasks for the development of IPTV strategies require specific need analysis of teachers and collaborative works of policy makers, teachers, researchers, and IPTV service providers.

The purpose of this study is to measure the impact of motivation on academic achievement and satisfaction of adult learners in an e-Learning environment, and to come up with strategies to improve the effectiveness of e-Learning for adult learners. In order to find answer, devices were developed, tested for validity and reliability, and use for testing variables for 289 adult learners. To measure the impact of achievement motivation on learning in job training, a multiple regression analysis was performed. The analysis results show that achievement motivation has an impact on academic achievement with significance level .001, but does not have an impact on a learner's satisfaction. Further analyses on the subcategories of achievement motivation show that individual-oriented motivation affects achievement with significance level of .001, while social-oriented motivation does not. From this finding, some strategies to boost individual-oriented motivation are suggested to enhance effectiveness of job training in e-Learning environment. Further strategies to boost individual-oriented motivation should be developed by studying various aspects of e-Learning such as learning environments, learning culture, learning modes and methods, and evaluation.

본 연구에서는 커널 퍼저인 Syzkaller 를 사용하여 리눅스 커널의 네트워크 서브시스템을 퍼징하고 그 결과를 분석하여, 높은 커버리지를 달성하기가 왜 어려운지 분석하고 이를 개선하기 위한 방법들을 제안한다. 첫 번째 실험에서는 TCP 및 IPv4 소켓과 관련된 시스템 콜 및 매개변수만 허용하여 리눅스 커널 네트워크 퍼징을 진행하고, 두 번째 실험에서는 Syzkaller 가 지원하는 모든 시스템 콜을 포함하도록 범위를 확장한다. 첫 번째 실험 결과, 퍼징 시작 약 55 시간만에 TCP 연결 수립에 성공하였다. 두 번째 실험 결과, 첫 번째 실험보다 전반적인 커버리지와 라우팅 서브시스템의 커버리지는 개선되었으나 TCP 연결 수립에는 실패하였다. TCP 연결 수립을 위해서는 서버의 IP 주소 및 포트번호를 클라이언트가 무작위 입력 생성을 통해 맞혀야 하는데, 이 과정에서 시간이 오래 걸리기 때문에 연결 수립이 쉽게 이루어지지 않는 것으로 분석된다. 추가적으로, 본 연구에서는 TCP 연결 수립을 쉽게 하기 위한 하이브리드 퍼징, IP 패킷 포워딩 허용, 패킷 description 없이 퍼징 등 Syzkaller 를 이용하여 리눅스 커널 네트워크 서브시스템을 더 효율적으로 퍼징할 수 있는 방법들을 제안한다.

This study examined traditional dance programs in cultural and arts education in local children's centers. We aimed to contribute to the voluntary and active participation of children in cultural and arts education through differentiated cultural and arts educational programs. Interviews were conducted from March 2016- June, 2016 at A Regional Children's Center in Chungnam. Once a week, a 50-minute were held 16 Session as "learning traditional joyful dance". After completing the program, 25 children who participated in the program were asked about the good points and disappointments regarding the program. The interviews used open, structured questions that have been primarily used in phenomenological research. The list of questions was prepared in advance according to the research purpose. The results of the study are as follows: The evaluation of the first program was generally positive. By experiencing activities through cultural and arts education through traditional dance programs for children, children learned to be polite. It also changed positively in conversation. Children who showed negative attitudes toward traditional dance programs gradually participated in activities. Second, I examined the evaluation of lecturers who teach traditional dance. The children's response to the program was positive, with sincere and responsible lecture preparation and progress. The instructor prepared the class in advance, welcomed the children and ran the class in good faith. Instructors who taught traditional dances were proficient in dance, majored in dance and teaching children. The learning effect was high by the instruction of the good dance movement. Rich in lecture experience, he is proficient in dealing with children in class. Material was delivered according to the child's dance level.
