The purpose of this study is to investigate a structural relationship among elementary students' self-determinant learning motivation, teaching-presence and learning outcomes (learning satisfaction, persistence) in blended learning environment. Participants were 5th and 6th grade students who enrolled in a mathematics learning service. The results showed that self-determinant learning motivation had direct effect on teaching presence, learning satisfaction and learning persistence. Teaching Presence had an direct effect on learning satisfaction and learning satisfaction had an direct effect on learning persistence. Based on the results, proper strategies were recommended to facilitate self-determinant learning motivation and teaching presence before and during learning since they play critical roles for the success of elementary students learning outcomes in a blended learning environment.

The paper studies the influencing factors of continuous usage intention for a scenario based cognitive FAQ service regrading on private information protection. The research result finds that three major factors are significantly positive to the continuous usage intention for the service. First, search easiness is an essential factor and it can be improved using sophisticate categorization. Second, Scenario based FAQ service is effective on understanding and solving questioner's situation. Related information is helpful for problem solving. The research shows that the new approach to private information protection area can lead to a more acceptable and reasonable problem solving tool.

Information and communication technologies(ICT) allow and force people to work anywhere, anytime using remote databases and application systems available in real-time twenty four hours a day and seven days a week. With the real time nature of ICT, individual work is becoming more and more fragmented. Instead of working on a similar task repeatedly, individuals are required to respond to e-mails and inquiries through social networks, work on planning documents, work on presentation documents, work on spreadsheets, input necessary data on company databases, generate necessary reports from the database, run teleconference, etc., all maybe in a day's work. Work fragmentation may impact negatively on productivity as the flow is interrupted, but it may increase the productivity by allowing people to handle multiple tasks in a shorter time period. This study explores the types of work fragmentation and their characteristics. An online survey was administered to collect data about work fragmentation and work characteristics including autonomy, complexity, flexibility, usage of ICT, etc. 300 cases were used in the analysis. Analysis of k-mean cluster indicated four different types of work fragmentation: concentrated, temporally distributed, spatially distributed, and fully fragmented.

This study has performed to find the effective method of human resource management in the hospital organization through the relationship between organizational attitude and individual inclination, where nurses, medical technician and administrative staff of hospital with labor intensive and relationship oriented organization were analyzed. According to the results, the lower individual inclination with changeable level of hospital employees, the higher of outer level and the higher of goal-oriented level, the organizational attitude was shown to be amicable, especially was most highly influenced by changeable level. Therefore, the hospital organization was recommended to find the following methods properly; no only to strengthen the active and logical outgoing tendency, the careful words and actions through the emotion control for the goal orientation, but also to minimize the changeable tendency such as not amicable human relation, the change and delay of decision.

Customized sleep care service needs to be provided differently for individuals since individual has different degree of sleep disorder. Because the brainwave data shows unique waveform characteristics for each person, this characteristic can be used to identify individuals. Personal identification provides an important role in enabling customized services. When you blink, you can obtain brain wave characteristics by measuring the area of the frontal lobe. Therefore, a real-time personal identification algorithm based on blinking EOG for customized sleep care service is proposed in this paper. For evaluation, 10 individuals were tested for personal identification accuracy. The results of the experiment confirmed that a maximum accuracy of 93% were taken. Algorithms can be developed by reflecting characteristics such as changes in the external environment in the future.

In this paper, we propose a personalized user authentication system (PUAS) that can be used in multiple stages in user authentication by customizing the password keyword to be used in user authentication. The proposal concept is that the user oneself defines the password keyword to be used in user authentication so as to cope with a passive retransmission attack which reuses the password obtained when the server system is accessed in user authentication. The authentication phase is also designed so that it can be expanded in multiple stages in a single step. Also, it is designed to store user-defined password related information in an arbitrary encrypted place in the system, thereby designing to disable the illegal access of the network. Therefore, even if an intruder accesses the system using the proposed system, it is possible to generate personal authentication information by generating a password keyword through unique personal information possessed only by an individual and not know the place where the generated authentication information is stored, It has a strong security characteristic.

인터넷이 발전함에 따라 기업의 업무, 커뮤니케이션 등이 온라인으로 전환되고 있으며, 정보 전달의 통로로써 전자 메일의 사용이 나날이 늘어남과 동시에 전자 메일을 통한 스팸메일의 폭발적인 증가로 인한 심각성 또한 대두되고 있다. 현재 스팸메일을 막기 위한 여러 가지 방법이 제안되었으나, 대부분 메일 서버내의 정책에 따른 메일 필터링 방식으로써 완벽한 스팸메일 탐지를 제공하지 못하며, 스팸메일로 인한 메일서버 및 네트워크 자원 손실 문제는 여전히 해결되지 않고 있다. 본 논문에서는 스팸메일 탐지율을 높이고 네트워크 내 자원 손실을 예방할 수 있는 SMTP 보안 게이트웨이를 제안하고자 한다. 본 SMTP 보안 게이트웨이는 스팸메일 차단 규칙에 의한 메일 필터링을 기본적으로 제공하고, 룰에 정의되지 않은 메일에 대해서는 사용자 선택에 기반한 메일 전송을 제공한다. 이는 규칙에 정의되지 않은 스팸메일에 대한 탐지 가능성을 높이며, 궁극적으로 메일서버의 자원 및 네트워크 자원의 가용성을 높일 수 있다.

The purpose of this study is to examine whether or not types of participation in the senior employment that greatly affect the level of life satisfaction is related to depression and to verify the relationship between life satisfaction and depression by using the correlation analysis. The findings of this study suggested that the effect of on the participation in the senior employment against the depression was positive(+) and the depression had a correlationship with life satisfaction. Therefore, the higher the number of participation in the senior employment for the public sector was, the lower the satisfaction of life, and the more time of participating in the senior employment for the private sector was, the higher the satisfaction of life. Based on the results of this study, in order to increase the satisfaction of senior life, the government, the local autonomous entity, and other companies should work together so that they can make a reasonable plan to create the employment of the private sector for jobs of the elderly.

The purpose of this study is to analyze the influence of the number of investors influencing the achievement rate of domestic securities type crowdfunding, to find out why the general investors need to participate and to suggest measures to increase the participation of general investors. The results of this study are as follows. First, the effect of the recruitment amount, the target amount, the recruitment period and the business training is confirmed as factors affecting the achievement rate of domestic securities type crowdfunding. And it was confirmed that the influence factors on achievement rate could have a greater effect as the number of general investors increased. Therefore, the government should make more effort to relax regulations on general investors, and the investor of capital should strengthen the public disclosure of KSM through the KSM market in order to recover the funds of general investors, Crowd funding will be able to attract enough funds.
