It is predicted the mass retirement of the post-war generation and the lack of young people according to reduces the recruitment. Therefore, industry fields are concerned by the low level of occupational safety and health from issued problem in a variety of industries; the charge of expanding business range/multi-functional, black box of technology, difficulty of systematic training, relative decrease in the skill of workers, loss of know-how in the field of information followed restricted site information. In response to these problems, it is necessary to establish the long-termly and actively based on for the adoption of a safety and health management techniques utilizing IT, which is digital assistant(tablet PC, PDA, etc.), RFID/USN/ICT, database systems, and etc. In this study, we developed and evaluated a worker's safety sensing apparatus using smart phone. The apparatus may be useful to prevent accidents in the construction industry as well as confined space work.

Although intensive development continues on innovative sensor systems, there is still considerable uncertainty in deciding on the number of sensors required and their locations in order to obtain adequate information on structural behavior. This paper is concerned with the sensor locations on a beam-structure for prognostic structural health monitoring. The purpose of this study is to investigate how to determine optimal sensor placement(OSP) from the sensitivity information of a known failure mode. The sensitivity of the forced vibration response of a beam to the variation of stiffness due to a crack is calculated analytically and used to determine the optimal sensor locations for the specified failure mode. The results of this method compared with the results of different OSP methods. The results have shown that the proposed method on optimal sensor placement is very effective in structural health monitoring.

This article is concerned with various aspects of establishing the global standard for occupational safety and health management system (OHSMS). The notion, main features, and brief history of the OHSMS are presented. The OHSAS 18000, its assets and liabilities, are reviewed as a prototype of the global standard. It is also addressed the possibility of combining ISO 9000(quality management system), 14000(environmental management system) and the OHSMS into the integrated management system (IMS) as a whole. The concepts of internal and external customers are presented to explain why the environment, safety and health should be incorporated into the notion of total quality 'Participation of the members' and 'standardization of the 4Ms (Man, Machine, Materials and Method)'are emphasized as the major enablers of the IMS. Finally, the industrial, academic and governmental roles are discussed for developing the IMS and setting it down into the Korean industries.

Recently, a great many people are concerned about promoting their health because medical science and scientific technology has become much larger and more develop. Thus, the person who interested in health wants to confirm his condition whatever he may take a meal or exercise. But it is disappointed of our expectation. By reason that many people doesn't know what changes will occur in their body. In this paper, we are going to introduce our Health Care Managing System which could display a physical variation, in addition, we will also propose how to control serial data from wireless sensors. We implemented this system using ZigbeX and Java application.

This paper is concerned with the attitude of the Guro inhabiants concerning medical care system in terms of the credibility of hospitals. The credibility may be consisted of three components : availability, friendliness, and expertness. These were considered as dependent variables. Independent variables were age/education/income/perception of differentiation. The questionnaire was administered to 127 stratified samples in Feb. 1982. The results were as follows : 1) The group whose age was above 50 years gave a favor for the medical care system in terms of credibility. This fact implied that cultural influence on the perception and attitude about medical care system was very crucial, and it was noticed that doctor-patient relationship have been changing. 2) The attitude of the inhabitants on the credibility was appeared generally as unfavorable and indifferent. 3) According to $X^2$-test, education, income, and perception of differentiation were identified as having statistically significant trelationships with friendliness factor.

Genotyping of Toxoplasma gondii has been performed in 23 PCR positive blood samples from stray cats in Korea. We used 2 separate PCR-restriction fragment length polymorphism (RFLP) patterns of SAG2 gene, amplifying the 5' and 3' ends of the locus. The results revealed that all samples belonged to the type I clonal lineage. Although T. gondii organisms were not isolated from the samples, the results of the present study represent that stray cats with T. gondii infection should be seriously concerned in our environment. Adequate and continuous control programs of stray cats are needed to reduce the risk of transmission of T. gondii as a zoonotic infection threatening the public health.

The purpose of this study was to measure the causal relationships between past consumption, health belief, subjective, attitude, intention and purchase of organic foods. Total 326 copies of questionnaire were completed. The structural equation model was used to measure the causal effect among constructs. The results demonstrated that the confirmatory factor analysis model provided a good model fit. The proposed model yielded a significantly better fit to the data than the baseline model and the extended model. The effects of past consumption, health belief and subjective norm on attitude and intention were statistically significant. The effects of attitude on intention and behavior to purchase organic food were statistically significant. As expected, health belief and subjective had significant effects on behavior to purchase organic foods. Moreover, past consumption, health belief and subjective norm had indirect influences on intention through mediated variables. Based on the empirical results and findings, some suggestions are provided to the institutions concerned so as to facilitate this organic sector's on-going expansion in the food industry.

The significance of father's parenting has been considered as a critical factor in facilitating growth and development and in promoting wellbeing of children. Pediatric nursing is a pertinent science to develop parenting roles, because it deals with knowledge and skills on growth and development and health of child. For this paper current studies were reviewed related to consequences to the family, content and factors influencing paternal parenting, and father's reactions to child rearing participation. Perspectives of future studies in pediatric nursing are summarized as follows. First, paternal parenting has to be studied more actively to contribute to family health and to meet the academic responsibility of pediatric nursing. Second, it is necessary to study the consequences to child's health and health behavior of paternal parenting. Also it is necessary to be concerned about fathers' reactions, like stress in parenting behavior, to understand the parenting father himself. Third, an objective measure of caregiving behavior (not self-reporting) is needed to determine whether the father is behaving appropriately. Further, experimental research has to be implemented to develop intervention programs for paternal parenting. It is hoped that the examination of these studies leads to develop of knowledge and practice in paternal parenting.

This study aims to ascertain occupations potentially at greatest risk of exposure to SARS-CoV-2 based on pre-lockdown working conditions in France. We combined two French population-based surveys documenting workplace exposures to infectious agents, face-to-face contact with the public, and working with colleagues just before the pandemic. Then, for each 87-level standard French occupational grouping, we estimated the number and percentage of the French working population reporting these occupational exposure factors, by gender, using survey weights. As much as 40% (11 million) of all workers reported at least two exposure factors. Most of the workers concerned were in the healthcare sector. However, army/police officers, firefighters, hairdressers, teachers, cultural/sports professionals, and some manual workers were also exposed. Women were overrepresented in certain occupations with potentially higher risks of exposure such as home caregivers, childminders, and hairdressers. Our gender-stratified matrix can be used to assign prelockdown work-related exposures to cohorts implemented during the pandemic.
