In recent years, due to a lack of expertise, many organizations have been devoting large portions of their budget to outsourcing. Outsourcing is now often regarded as a solution for all problems. However, the lack of clear understanding of the effectiveness of outsourcing could lead to many problems in organizations even though outsourcing is known to provide advantages to some organizations. Moreover, outsourcing could have a negative effect on knowledge management in some aspects. There have been and continue to be numerous studies into outsourcing; however, their findings primarily relate to cost reduction in short-term. Regardless of increasing demands on outsourcing and the importance of knowledge management, little research has focused on decision-making structure from knowledge management perspective. This paper attempted to quickly identify promising movements with potentially significant effects on IT/IS outsourcing.

This study was performed with the questionnaire survey on mercury knowledge and mercury exposure avoidance behavior, which was conducted among 1076 dental personnel in September, 2004. As for the factors effecting the mercury knowledge, it seems that they are closely related with the personnel's educational backgrounds, and their understandings of causing environmental hazardousness in the dental offices. And also, the factors effecting the behavior of mercury exposure avoidance are strongly connected with the knowledge points on mercury, the knowledge of air states in the dental clinic offices, the use of pincettes and gloves in squeezing, and rubber dam and gloves in mulling, the experience of environmental education on mercury, etc. In the survey, the higher points in mercury knowledge is closely related with the higher points in the behavior of mercury exposure avoidance. Nevertheless, the very fact that the lower points in the behavior among personnel takes on the aspect of the relatively higher points in knowledge on mercury may be understood that the generally acquired knowledge on mercury cannot be the critical factor of the behavior of mercury exposure avoidance.

The purpose of the study was to develop an internet nutritional counseling program using an expert system to assist obese people to lose weight through behavior modification. The internet counseling program for weight loss was developed by the accumulation of knowledge dealing with eating habits and exercising behaviors in expert system tool, Knowledge Engineering Agent (KEA) by a dietitian without any help of computer expert. To accumulate knowledge into KEA, survey was performed in 150 obese people, dietitians reviewed and consulted each survey case, and the consulted contents were learned and accumulated into KEA. Survey questionnaire was the same as that of the internet consulting program, and it included general characteristics, dietary habits, lifestyle, and exercise patterns related to obesity. Also, the dietitian selected proper factors inferred from the survey questionnaire of each case, and added the conclusions for them. Conclusions were made for helping clients to correct bad eating behaviors and accumulate good behaviors to lose weight. Counseling was divided into two parts; a two-week part and a daily part. Two-week counseling was performed based on 4 step questionnaires, and daily counseling was done for daily food consumption and physical activity. When clients answered survey questionnaires in a counseling internet program, the recommendations on how to eat, to exercise and to deal with stress in a real time for each case, was given. In conclusion, a counseling internet program for weight reduction can be used to give advices how to deal with obesity in a man-to-man way in a real time using KEA where nutritional knowledge based on behavior modification for weight loss was accumulated.

Cancer is one of the leading causes of death in Thailand as well as other countries. Evidences from studies in Asia show that alcohol consumption has been linked to an increased risk for various types of cancer. In the qualitative participatory action research presented here, the possibilities of a volunteer women's movement to reduce harmful alcohol consumption by facilitating the creation of emancipatory knowledge in the Thai-Isaan community was explored. During in-depth interviews with 10 female volunteer participants, the following themes emerged: merit making, developing a sense of personal empowerment, and the experience of participating in an action plan that utilized various strategies. The project activities empowered participants to create and share knowledge which was then applied toward action for change. Adoption of this type of program by local health care providers to reduce health problems and risks related to alcohol misuse in similar contexts and cultures is recommended.

Gustation, initiated by the detection of taste molecules by specific receptors expressed in taste cells, plays an essential role in food selection and consequently in overall nutrition for humans. In the past decade, a remarkable amount of knowledge of taste perception in the neurology, molecular biology, and genetics has emerged, particularly in basic tastes- sweet, bitter, sour, salt and umami. Among them, sweet, bitter and umami are recognized via the specific G-protein coupled receptors. Salt and sour are primarily mediated by apically located ion channel-type receptors. Because excessive salt or sugar consumption leads to high rates of diet-associated diseases and it comes from eating prepared or processed foods, an understanding of the underlying mechanisms in salt and sweet perception is crucial in food industry. This review will focus on recent progress of the perception of salt and sweet taste to provide basic knowledge for reducing salt and sugar consumption.

This study aims to investigate effects of scaffolding on writing apprehension and media literacy in engineering freshmen's synchronous online writing course, and the relationships between the two variables. 'Scaffolding' is in-time support provided by a teacher/tutor or competent peer that enables students to meaningfully gain skills at problem solving process. Also, it is one of the most frequently mentioned concepts in education as well as one of the more necessary teaching strategies in an online writing course. In this study, provided treatments for the experiment were supportive scaffolding for domain-specific knowledge and reflective scaffolding for meta-cognitive knowledge. Participants were 102 engineering undergraduate students, who were assigned to two experimental groups by scaffolding types. A process-based writing course in online learning environment was conducted for 8 weeks. The writing tasks were given according to writing process. The findings were that, firstly, there were statistically significant writing apprehension's reduction and self-expression's improvement through the scaffolding provided in writing class. Secondly, writing apprehension's reduction and self-expression's improvement were significant in supportive scaffolding group. Thirdly, media literacy predicted writing apprehension. The practical implications of these findings are discussed herein, with particular attention on ways for writing apprehension's reduction as well as media literacy's enhancement.

This paper presents a methodology in which the knowledge of design intents and change requests is communicated unambiguously cross collaboration partners through features. The domain of application is focused on the plastic part design for enabling effective collaboration between the product design and plastic mold making. The methodology takes the feature-based design approach and allows design features and knowledge to be reused in plastic injection mold design. It shortens the mold design lead-time, reduces mold design efforts, and enables unambiguous and fast design change management between product and mold designers. These contribute to the reduction of product development cycle time.
