This study was carried out with 2,195 boy and girl middle school students in Inchon to examine environmental elements which may change vision and cause shortsightedness, and also to find out common knowledge of eye health. Its results are as follows. 1) As school year goes up, the normal eye sighted diminish but the visually handicapped regardless of left and right eyes increase. 2) Among weak sighted students below 0.9, boys are 42.2% and girls are 55.3%, the latter are larger by 13.1 %. Vision weakens rapidly especially for third year girl students. 3) Environmental, individual, everyday life elements which cause shortsightedness are studied, (1) environmental elements; illumination in watching TV and studying (2) individual elements; distance from TV and books, posture in studying (3) everyday life elements; hour of watching TV, hour of using game tools average, hour of studying 4) Knowledge of eye health is generally poor without regard to sex and wearing glasses. So adolescent students are in advance educated proper eye care to prevent shortsighted elements.

Due to advance in Internet technology, most tourists tend to search travel information in the Online Travel Communities(OTC). Given this new paradigm in terms of finding travel information, most of relevant studies in this area are still dealt with explaining tourists' behaviors regardless of the types of communications. Therefore, to overcome some limitations in previous studies, we attempt to examine the relationships between both formal and informal communications and tourists' behavioral changes in the OTC context. Specifically, we developed a research model by employing the PPM(push-pull-mooring) framework and tested it to understand why and how tourists' behaviors might be changed. Survey data collected from 323 online tourists were used to test the model the model using SEM(structural equation modeling). The implications of our empirical findings for both research and practice are discussed.

A fuzzy learning control algorithm is proposed in this paper. In this method, two fuzzy controllers are used as a feedback and a feedforward type. The fuzzy feedback controller can be designed using simple knowledge for the controlled system. On the other hand, the fuzzy feedforward controller has a self-organizing mechanism and therefore, it does not need any knowledge in advance. The effectiveness of the proposed algorithm is demonstrated by experiment on the position and force control problem of a parallelogram type robot manipulator with two degrees of freedom. It is shown that the rapid learning and the robustness can be achieved by adopting the proposed method.

Purpose - The aim of this study is to evaluate the effectiveness of a corporate training program. The case study of HCL Technologies was used to investigate how training programs improve the performance of employees on the job, as well as to identify unnecessary aspects of the training for the purpose of eliminating these from future training programs. Research design, data, and methodology - An exploratory research design was used to conduct the study. The research sample size included 50 HCL employees. The sampling technique for the data collection was convenience sampling. Results - Training is a crucial process in an organization and thus needs to be well designed. Specifically, the training programs should provide adequate knowledge to all employees, ensure correct methods are used for the selection of trainees, and avoid any perception of biasness. Conclusions - Employees were not fully satisfied by the separation of the training program into two parts, on the job and off the job training, but if sufficient data is provided to employees in advance, this could help them during the training process.

Virtual reality (VR) simulators have been extended to transfer knowledge and education, and demands for exhibition systems for science education and cultural experiences has also increased. Existing VR simulators, which are based on the dynamics equations of motion, cannot easily be adapted to changes in simulation contents. In order to effectively transfer knowledge and maintain interests through educational applications, an experiential system that has multi-sensory effects as well as motion effects is required. In this study, we designed and implemented a motion generation that is tailored to experiential exhibition systems and multi-sensory VR effects. Both the sense of motion which is generated from the movement of the viewpoint of the visual image, and motion effects which are constructed in advance, are applied to motion simulation. Motion effects which occur during interaction between the user and the exhibition system can be easily added. Various sensory cues that are appropriate to the exhibition system are also considered.

Better utilization of the knowledge of employees in any organization has long been accepted as a vital component of a corporation's competitiveness. This has been considered even more important in the construction industry due to the dynamic and intermittent nature of construction projects. With the rapid advance of network technologies during the last decade, construction companies quickly shifted their focus of knowledge management to interactive online repositories. However, the efforts of leveraging organizational knowledge has remained fragmented in the construction industry until recent years. In addition, companies have begun to realize that actual returns on this investment in network technologies would be far less than initial expectations if online efforts do not incorporate companies' general offline knowledge management efforts, which are done without the use of computer network. Thus, this paper focused on assessment of implementing current Lessons-Learned Systems at the large construction companies in Korea to provide the foundation for developing a renovated conceptual Lessons-Learned System model.

The breast feeding habits of 507 college students were evaluated between March 27 to April 26 (2006). Data were collected from self-administered questionnaires and analyzed using SPSS for Windows V.12.0. The study population consisted of 245 (48.3%) male and 262 (51.7%) female college students that answered ‘yes’ when asked whether they had been breast feed. A total of 52.7% of the study population were fed with breast milk (most frequent answer), as opposed to 11.0% that were fed with infant formula (least frequent answer) during their infancy. When asked whether they ever got educated on breast feeding, 78.1% of the college student subjects answered ‘no’. A total of 95.1% of the female college students replied ‘yes’ when asked if they intended to breast feed their child. Moreover, 62.2% of the college student subjects indicated that their parents had an influence on their decision to breast feed. A comparison between male and female college students indicated that female college students had a superior knowledge level of the general characteristics of breast feeding over the male subjects (p<0.05) . Moreover, a comparison of the different levels of college attained suggest that freshman college students had the highest knowledge level, followed by senior, sophomore and junior college students in terms of advantage, BF Tabu (p<0.05). Also, students provided with education on breast feeding had a higher knowledge level than college students with no formal education. In summary, the results suggest that the knowledge on breast feeding in college students were different by general characteristics such as gender, major and school year, and education on breast feeding in advance was appeared to be an important factor, therefore nutritional education course on breast feeding is recommended for the college students.
