Opisthorchis viverrini is an ongoing public health problem in Northeast Thailand. Despite continuous efforts for decades by healthcare organizations to overcome this problem, infection rates remain high. To enable related personnel to identify and address the various issues effectively, a cross-sectional study was performed to investigate prevalence and risk factors for opisthorchiasis. The target group was 3,916 Thai residents of Northeast Thailand who were 15 or over. Participants were recruited using the 30 clusters sampling technique. The data were gathered through questionnaires, focus group discussions, in-depth interviews, and stool examinations for parasite eggs (using the Modified Kato Katz method). The data were analyzed using descriptive and inference statistics; in order to ascertain the risk factors and test them using the odds ratio and multiple logistic regressions. The prevalence of opisthorchiasis was 22.7% (95%CI: 0.26 to 0.24). The province with the highest prevalence was Nakhorn Phanom (40.9%; female to male ratio =1:1.2). The age group with the highest prevalence was 40-49 year olds. All age groups had a prevalence >20%. Four of seven provinces had a prevalence >20%. The factors related to opisthorchiasis were (a) sex, (b) age (especially > 50), (c) proximity and duration living near a water body, and (d) eating raw and/or fermented fish. In order to reduce the prevalence of opisthorchiasis, the focus in populations living in upper Northeast Thailand should be changing their eating behaviors as appropriate to their tradition and context.

The Chemical Substances Control Act has been legislated to counter the risks posed by chemical substances to public health and the environment, but a number of small- and large-scaled incidents related to hazardous chemicals continue to occur every year. The Korean Ministry of Environment takes legal responsibility for prevention, preparedness, and response to nationwide chemical accidents under the Chemical Substances Control Act. The determination of chemical accidents that occur during hazardous chemical handling processes is based on the Article 2 (Definitions) of the law and the administrative criteria for judgement of chemical accidents. However, there are certain ambiguities in the scientific basis for determining chemical accidents under the current regulations. Whether or not a chemical accident has a direct influence on penalties and administrative measures for a workplace where an accident occurred, it is necessary to find reasonable criteria for determining chemical accident based on legal and scientific evidence.

The purpose of this study was to examine the current office work environment and suggest the needs for improvement the quality and efficiency of work. To fulfill this task, information describing various environmental conditions was gathered from generally large offices in Pusan and Major cities in Kyoungnam. Data were collected on questionnaire's general information, lighting, air quality, temperature, health problems, noise and equipment arrangements, and the size fo workspace. The extent to which the attitudes and behaviors of workers were related to these environmental conditions was then examined and scrutinized. According to the development of office automation, the interest in improvement of office environment become increased. Workstation size, individual environmental control, health care, adequate storage space and noise control should be recognized as critical to the worker's environmental satisfactiov. Finally, based on the results of this study, a number ofrecommendations can be made for alleviating some of the problems that have been identified. Designers should be interested in knowing if their environments actually function in the manner in which they were intended.

The objective of this study is to perform an analysis of the heat(heating and cooling) and lighting energy consumption according to the window area ratio and the application of horizontal louver, which is external shading device installed for the purpose of energy savings in office buildings. For this, a building was chosen as a typical example, and the heat and lighting energy consumption was calculated by using the daylight and building energy analysis simulation. The results showed that the total energy consumption, when the lighting control was applied, was reduced by an average of 11.49[%] compared to when there was no lighting control. The smaller the glazing ratio is, the less the total energy consumption is. Also, the application of the horizontal louver increases the total energy consumption under the same condition of glazing ratio.

A high rock embankment by means of dynamic compaction has hardly carried out in domestic area. For the successful accomplishment of such a high rock embankment, construction quality and measurement control are conducted. Plate loading tests are carried out to verify the bearing capacity and safety against the long term settlement. In addition, settlement of each layer is measured in order to verify the effect of dynamic compaction and to predict long term settlement.

Purpose: The purpose of this study was to examine the effects of a walking program for office workers in terms of social cognitive theory, walking activities and physiological indexes. Methods: A nonequivalent control group pretest-posttest design was used. The sample consisted of 50 office workers who were identified as having low levels of physical activity according to the International Physical Activity Questionnaire (IPAQ Research Committee, 2005). The participants were recruited from two companies in Seoul. Of the 50 participants, 26 were assigned to the non-equivalent experimental group and 24 to the control group. The walking program consisted of six didactic sessions via e-mail, two individual telecoaching sessions and three support group meetings over ten weeks. Data were analyzed using SPSS 17.0 program. Results: The non-equivalent experimental group reported significantly higher posttest scores in walking activities and adhering to the walking protocol than the control group. There were no differences in reported self-efficacy, outcome expectations, body mass index and blood pressure between the two groups. Conclusion: These findings indicate that a walking program based on social cognitive theory is effective in increasing physical activities for office workers.

This paper presents a structural design of the "(Tentative Name) Toranomon Hills Residential Tower" which is currently under construction in Tokyo. The building is a reinforced concrete high-rise residential complex building with 54 stories above ground, 4 basement levels, and a building height of about 220 m. It is a requirement to provide the highest grade of residence in Japan, and in terms of the structural design, it is required to provide wide and comfortable spaces with high seismic performance. These requirements are satisfied by providing a total of 774 vibration control walls of two types. Also, to further improve the structural performance, steel fibers at the rate of 1.0vol% are provided in the ultra-high strength concrete used in the column members.
