The safety and health ledger system, which gives the responsibility of safety and health management for construction site workers to the construction project owner, was introduced as part of the overall revision of the Occupational Safety and Health Act. There is a need to explain the system's effectiveness in terms of economic feasibility to solve the execution problem of the system caused by low awareness and implementation rate. In this study, the economic effect of implementing the safety and health ledger system was analyzed using cost-benefit analysis based on the data discussed at the time of the introduction of the system. Results show that creating and managing the design safety and health ledger caused additional costs in implementing the system. As a result of comparing the cost of preparation and the direct and indirect benefits caused by the reduction of industrial accidents, the benefits were evaluated higher than the costs. Thus, it is thought that the safety and health ledger system reduces construction work accidents and generates economic effects.

In the past 20 years, accidents in the construction industry have declined in absolute numbers. On the other hand, disasters occurring at small and medium-sized construction sites account for more than 80% of the entire construction industry and are showing a continuous increase. A system for preparing a safety and health register in stages was enacted to preemptively prevent accidents by mandating responsibility for safety to owners with relatively strong authority in the construction industry. Considerable is needed to become an effective legal system. Although there have been many studies related to safety management plans and hazard prevention plans, there are no studies on the safety and health register. Therefore, in this study, an improved safety management procedure connected with the orderer's safety and health management procedure was presented as a plan for reducing accidents at small and medium-sized construction sites. All information was made as a data-based procedure to reduce the burden on the manager. The results of this study are expected to be used as basic data for the development of a safety management support information system for small and medium-sized construction sites.

A total of 136 coliform bacteria isolated from spring water (112 strains) and ground water (24 strains), submitted to Seoul Health and Environmental Research Institute from June to July in 1997, were characterized biochemically and microbiologically. Colonical characteristics of each isolate were also noted, including color and texture on EMB agar. Among the 136 isolates, 50.7% were greenish metallic sheen color, 44.2% were pink and 5.1% were violet. The sixty four percent were smooth, 34.6% were mucoid and 0.7%. were rough. Twenty three bacterial species were identified by IMViC and API 20E test. Among the 136 coliform bacteria known to species, 39 isolates (28.6%) were Escherichia spp., 32 isolates (23.5%) were Klebsiella ssp., 30 isolates (22.1%) were Enterobacter spp., 19 isolates (14.0%) were Serratia spp., 6 isolates (4.4%) were Citrobacter spp., 4 isolates (3.0%) were Kluyvera spp. and 7 isolates (5.1%) were other bacterial species. Strains, which were gas-positive in lactose broth but gas-negative in Kligler Iron Agar were Ent. intermedium, Ser. liquefaciens, Ser. marcescenes and Salmonella arizoae. Strains, which were H2S production were also Kleb. pneumoniae, Kleb. oxytoca, Kleb. ornithinolytica, Ent. sahazahii, Ent. cloacae, Ser. liquefaciens, Ser. fica ria, Cit. freundii and Sal. arizoae. In the present study, most of coliform isolated from spring and ground water were E. coli, Klebsiella spp. and Enterobacter spp. Since coliform with pink colony in EMB agar was isolated as frequent as coliform with greenish metallic sheen colony, coliform with pink colony should be considered as important colony. Our results suggested that new coliform strains may be emerging on the basis of biochemical and microbiological testes.

Food-Health indicators have been developed and utilized internationally in the 'Food' domain of environment and health indicators. In Korea, however, Food Safety Health Indicators which are in the introductory stage had been developed separately from Environmental Health Indicators. The aim of the current study is to suggest feasible applications of the domestic Food Safety Health Indicators as a case study. We introduced 3 possible applications which are as follows: 1) production of two types of Integrated Food Safety Health Index; 2) conduction of correlation analysis between the Integrated Food Safety Health Index and Food Safety Health Indicators; 3) conduction of regression analysis to evaluate the relationship between the Integrated Food Safety Health Index and socioeconomic status. As a result, we provided the calculated Integrated Food Safety Health Index I and Integrated Food Safety Health Index II, which represents the regional food safety level in relative and absolute terms, respectively. Integrated Food Safety Health Index I was significantly correlated with the outbreaks of food-borne diseases (caused by Campylobacter jejuni, Bacillus cereus, Salmonella spp. and unknown cause) and incidence of E.coli infections. Integrated Food Safety Health Index II significantly decreased as the proportion of foreigners and women increased, and increased as the population density increased. Utilization of such Integrated Food Safety Health Indicators may be helpful in understanding the overall domestic food safety level and identifying the indicators which must be considered with priorities to enhance the food safety levels regionally and domestically. Furthermore, analyzing the association between Integrated Food Safety Health Index and factors other than food safety could be useful in conducting risk management and identifying susceptible populations. Food Safety Health Indicators can be useful in other applications, and may serve as a supporting material in establishing or modifying policy plans to enhance food safety. Therefore, keen interests by researchers accompanied by further studies on food safety health indicators are needed.

Since the discovery that Mycobacterium aviumsubsp. paratuberculosis (Map) is the causative agent of Johne's disease (JD) in cattle at the end of the nineteenth century, movement of livestock latently infected with Map has led to the spread of JD throughout the world. A new form of enteritis with clinical features of JD in cattle appeared in humans concurrent with the appearance of Map as a disease problem in livestock. The demonstration that Map is a zoonotic pathogen and the causative agent of the new form of enteritis in humans, however, wasn't recognized until late in the twentieth century when methods were developed to detect the presence Map in tissues from patients with the new form of clinical enteritis. The objective of this short review is to provide a brief history explaining how Map has become a major disease problem in livestock and humans and then provide a review of the progress that has been made in treating patients with an enteritis caused by Map and the strategies underway to develop a vaccine to control infection in livestock.

Purpose: It Vas intended to identify problems and derive improvement plans by grasping the current status of safety management of public institutions among construction Vork orders. Method: By comparing the disaster status of public institutions compared to the total construction Vork, the analysis Vas conducted based on the results of the evaluation of the level of safety activities of public institutions Vith a high disaster rate and the results of actual consulting. Result: As a result of comparing and analyzing the current status of safety management of public institutions, the current status and problems of safety management in public institutions Vith a high accident rate Vere similarly discovered. Safety management organizations, document management systems, safety management systems, and risk assessment activities are operated Vithout reflecting the size and characteristics of the organization, so improvement in the relevant field is needed. Conclusion: Safety-related professionals and organizations should be formed according to the size of construction orders, and responsibility and authority should be clearly assigned. Since risk assessment is conducted formally to prepare a safety and health ledger, it is necessary to derive risk factors to prevent safety accidents for the actual construction. It is expected that the level of safety activities can be improved if it is improved by reflecting the size and characteristics of public institutions.

The consumption of ready-to-eat side dishes is rapidly growing in South Korea. These foods are particularly vulnerable to microbiological contamination as they are often cooked without any treatment, such as heating or stored at room temperature after cooking. Hence, in 2022, we analyzed the ready-to-eat side dishes sold in Gyeongsangnam-do, South Korea for microbiological contamination. We collected 100 samples from supermarkets in 7 cities, and then examined them for presence of food-borne pathogens and sanitary indicator bacteria. In the analysis of the food-borne pathogens, Bacillus cereus and Clostridium perfringens were isolated from 51 samples (51.0%) and 3 samples (3.0%), respectively. However, both quantitatively met the Korean Food Standards Codex. Genes of five different enterotoxins and one emetic toxin were analyzed from the 51 isolated B. cereus strains. We detected enterotoxin entFM (100.0%), nheA (94.1%), hblC (58.8%), cytK (56.9%), and bceT (41.2%) in 51 isolates, and emetic toxin gene, CER, in only one (2.0%) isolate. We did not detect C. perfringens toxin gene (cpe) that causes food poisoning in any one of the three C. perfringens isolates. In the case of sanitary indicator bacteria, Kimchi had the highest levels of total aerobic bacteria and coliforms, followed by Saengchae, Jeotgal, Jeolim, Namul, and Jorim, respectively. We counted total aerobic bacteria at two different storage temperatures (4℃ and 20℃) to determine the effect of storage temperature. When stored at 20℃, total aerobic bacteria count increased in most of the ready-to-eat side dishes, except for Jeotgal. This result conclusively shows the need for refrigerating the ready-to-eat side dishes after purchase. Further research is needed to assess the risk and safety of the ready-to-eat side dishes available in the market and determine appropriate safety management practices.
