This study aimed to compare general and female health-related factor between day-work and shift-work worker. It is based on the data of the Korea National Health&Nutrition Examination Survey(KNHANES) 2nd year on 7th period. The number of participants was 10,430. Out of the participants, 1,995 workers' dara was analyzed. The age, marital status, education level, occupational status and childbirth experience of female workers indicated significant differences between day and shift work. By contrast, health-related quality of life did not represent significant differences these factors; income, subjective health cognition, stress perception, depression experience, menarcheal age, menopausal age and breastfeeding period. The shift work is inevitably implemented as an industrial development and flexible work hours. Therefore, social and national attention and measures as well as those of individual workers are required to reduce the side effects from shiftwork.

We developed an authoring tool for designing vibrotactile patterns quickly and easily by using the drag-and-drop paradigm in mobile devices. Designed vibrotactile patterns are registered into a data pool in the XML format, improving the reusability and extensibility of vibrotactile patterns. A multi-channel timeline interface is also incorporated to provide time-synchronized pattern editing for multiple vibration patterns (for multiple vibration actuators). In addition, an internal vibration player is embedded in the authoring tool in order to evaluate the patterns on the spot. A transform function for perceptually transparent vibration rendering can also be set in the editor. Although the authoring tool was developed for mobile devices, it can be used for other applications such as haptic interaction m virtual reality.

The purpose of the study is to investigate the students' learning motive through the application of the learner-centered program Creative Teaching Technique(CTT) conducted by undergraduate school of Medical Record Information Management(MRIM), and to improve learning from the results. A questionnaire survey was carried out that started March to June 2013 among the sixty freshmen college students from the Health Administration Department who participated in the CTT during the 12 weeks training. The main results are as follows. The subjects' cognitive results form CTT were relativiely higher in 'increased voluntary participation(4.03)', 'improved concentration(4.00)', 'increased understanding(3.97)' in order. The effects of the tools used in CTT were higher as well in 'two members in a tem(4.08)', 'three-dimensional tools(4.03)' and 'quiz cards(3.95)' in order. While undergoing CTT, the learners considered reviewing repeatedly the content before starting and finishing as mostly helpful. Concludingly, this learner-centered CTT program identified having positive effects on their participation, concentration and understanding. To maximize the learning effects, development and activating a systematic, continuous and supportive program like this CTT is highly recommended.

최근 청소년층의 인터넷 이용이 급격히 증가하면서, 초등학생 중 90% 이상이 인터넷을 이용하고 있으며, 그 연령대도 낮아져 저학년 어린이의 이용률이 지속적으로 높아지고 있다. 또한 청소년의 30%가 인터넷 중독 또는 중독 직전에 있는 것이 실태이기도 하다. 10대가 현재 가장 많이 사용하고 있는 정보매체인 컴퓨터는, 그것을 사용함에 있어 교육적으로 도움이 되는 면도 있지만 반면에 무분별한 인터넷 용어나 비속어의 사용, 무절제한 지속적인 이용, 유해사이트에의 노출 등 많은 문제가 산재해 있다. 기존의 유해사이트 차단과 컴퓨터 사용시간 제한 등의 사용 관리를 위한 프로그램들이 많이 선보여진 상태이지만 그 활용 면에서 보면, 좀 더 사용자의 특성을 이해하여 어른들보다 절제가 어려운 어린이 사용자를 위해 부모 혹은 선생님과 같은 관리자와 가르침의 역할을 해줄 수 있는 부분이 더욱 필요하다. 본 연구에서는 무형의 소프트웨어 프로그램이 사용자에게 명령을 내리고 그것을 수행하게 하는 것 보다, 사용자가 친숙하게 받아들이고 정서적으로 접근할 수 있는 사용자와 인터렉션이 가능한 캐릭터 형태의 물리적 아바타를 제안하고자 한다. 또한 비속어나 그와 비슷한 단어들을 사용할 시 의미적으로 비속어인지 아닌지 아바타가 추론할 수 있는 기능으로, 인공지능을 부여하여 사용자가 인터넷 채팅이나 게임을 할때 아바타로 하여금 사용자와의 인터렉션을 통해서 올바르지 않은 언어사용에 대한 인지를 쉽게 하고 개선의 효과를 높이며 지속적인 관심을 이끌 수 있는 인공지능을 가진 캐릭터 아바타를 제안하고자 한다.

Most of the university libraries in Korea provide digital reference service(DRS), but the use of DRS is very low. The low usage of DRS seems to result from the lack of subject librarians, of staff, of public relations, and of managers' enthusiastic attitude and understanding of DRS. It is difficult to solve these problems because of the poor circumstances in universities. The collaborative digital reference service(CDRS) is a solution to these problems. Not only CDRS costs little but also can provide reference services in many different subject areas. Though subject specialist librarian, user-friendly system interface, system programs and administrative supports are necessary to implement CDRS, the education and training of the subject specialist librarians is the most important work to be done in the university library situation in Korea.

This study analyzes a correlation between organizational commitment, work values, job satisfaction and loyalty of the middle management in hotel enterprises. In other words, this research aims at drawing up theoretical and working-level implication through establishing the competition model of parameters and independent variables, which have an effect on loyalty of the middle management in hotels. Analysis showed that work values of the middle management play not a key role to mediate between organizational commitment and job satisfaction, and that internal values are higher than external values in route analysis of work values. Meanwhile, it was analyzed that the middle management of hotels make a long-service commitment with great satisfaction on the job. But there was no connection between their job satisfaction and loyalty. Consequently, it was confirmed through the analysis of the competition model that they rather attach significance to internal values and specificity of the hotelier than their satisfaction with work because of economic stability, and the loyalty of the middle management responds sensitively to the organizational commitment variables as a permanent job, sense of belonging, self-esteem.

Since assembled temporary equipment is widely used for construction work that should be carried out before this construction begins, it is essential to secure quality during assembly and prevent safety accidents caused by assembled temporary equipment after installation. However, it was investigated that most construction site managers are not aware of its importance, such as recognizing the quality management of assembled temporary equipment as a task of managing temporary structures that are dismantled after installation for this construction. The quality management work of assembled temporary equipment at the construction site is carried out in different ways for each construction site because there is no formalized procedure and the subject of performing. In addition, it is analyzed that the manager of the general construction company inspects and reflects the parts that need to be inspected without evidence, so transparency is not guaranteed and the result leads to a serious disaster. Therefore, the purpose of this study is to establish a document preparation-oriented system that provides systematic quality evaluation and management procedures for securing the quality of assembled temporary equipment, develops a checklist for quality evaluation and management, and supports history management on the web.

This study investigates the effects of trust and distrust on intention to purchase in open markets, based on the ideas derived from previous studies such as coexistence of trust and distrust, and two distinct trustees in open markets-intermediary and sellers. Specifically, this study i) proposes a trust-distrust model of intermediary and sellers, ii) explores the transfer of trust and distrust from intermediary to sellers, and iii) discovers the antecedents of trust and distrust. The empirical validation using Partial Least Squares shows three results as follows. First, trust in intermediary positively affects intention to purchase through the mediated impact of trust in sellers. That is, trust in intermediary transfers to trust in sellers. Second, distrust in intermediary negatively affects intention to purchase through the mediated impact of customers' perceived risk. Third, structural assurance and perceived website quality positively affect trust in intermediary. The results of this research have implications for intermediary firms not only to build trust but also to manage distrust level. However, this study could not identify any antecedent of distrust, so further research for these antecedents will be needed in the future.
