The use of cultured meat, also known as in vitro meat, is claimed to be a way of meeting the growing demand for meat worldwide in a safe and disease-free manner, without sacrificing animal and lowering greenhouse gas emissions. However, its economic feasibility is limited by its cost, scale-up complexity, public neophobia and technophobia, and an imperfect knowledge of its impacts on human health. Cultured meat, which is obtained from stem cells using tissue engineering techniques, has been described as a potential alternative to the current meat production systems, which have extensive negative effects. To ensure that a food product is safe for human consumption, it is important to consider all aspects of its life cycle. In this context, the current review analyzes the major elements of the cultured meat life cycle, including the incorrect use of chemicals, such as pesticides or antibiotics, as well as improper processing and storage methods that determine the food safety of cultured meat. The purpose of this review is to determine food safety, health issues, and the potential risks associated with cultured meat production.

This Study was conducted at nine Histological Laboratories in the hospitals located in Seoul from August 20 to October 10, 1996. The main purpose of this study was to assess the TWA & STEL exposure to formaldehyde and to evaluate factors affecting formaldehyde concentration in Histological Laboratory. With evaluated factors, proper improvement strategy to minimize exposure was suggested. The results are summarized as follows ; 1. The TWA concentrations of the personal samples ranged from 0.02 to 3.86 ppm and that of one laboratory out of nine was exceeding 0.75 ppm, USA OSHA standard. The TWA concentrations of the area samples ranged from 0.08 ppm to 1.49 ppm and those of three laboratories out of nine were exceeding OSHA standard. 2. When measurement was conducted on the working tables. around Formaldehyde vessel, fixation container and storage cabinet, the geometric means of TWA concentrations were 0.62 ppm, 0.64 ppm. 0.58 ppm and 0.37 ppm respectively. 3. When overnight fixed specimens were examined, the STEL concentrations of personal samples ranged from 0.59 ppm to 5.01 ppm, those of three laboratories out of nine were exceeding 2 ppm, OSHA standard and the STEL concentrations of area samples ranged from 0.31 ppm to 3.08 ppm, those of four laboratories from nine were exceeding OSHA standard. 4. Factors affecting Formaldehyde exposure level were sanitation state of laboratory, volume of the room and opening state of fixation container & formaldehyde vessel(p<0.05).

In order to estimate the utilization pattern of a rural health subcenter, and to identify the recognition for it among the inhabitants in Kogsung district, a questionnaire survey was carried out for objects of 708 population. The results observed were as follows; 1. The annual utilization rate of a rural health subcenter for a basic health service unit was 27.5 per 100 persons, and annual mean visiting times was 1.43 times. 2. The most frequent disease by, annual health subcenter utilization illness was respiratory disease(26.5%), and the next was musculoskeletal disease(23.9%), gastrointestinal disease(15.9%) by order. 3. Favorite reasons for community health subcenter utilization were lower medical cost(23.4%), near distance from living place(20.7%) and lower disease severity(19.5%) by order. But disfavorite reasons for it were non effective treatment(26.2%), insufficient equipment(25.4%) and absence of specialist(17.4%) by order. 4. Insufficient items about community health subcenter utilization were restriction of treatment limit(47.1%), lower reliance(22.4%) and not punctral(21.8%) by order. 5. The results of logistic regression analysis suggested that statistically significant factors in health subcenter utilization were age, educational level and the nearest medical facility class. 6. There was no difference between recognition for a community health subcenter's work and actual utilizing service, and desirable works for it were disease preventing service, disease control of elderly and sanitation control by order. These results suggested that to increase the utilization of rural health subcenter and to promote the accessibility of rural residents to primary health care, there must be considered public relation about health subcenter, expansion of health equipment and recognition about access time.

This paper is examine the mutagenic activities of the water samples from Chun-gye and Joong-rang streams in March, 1968. For this examination, adsorbed of mutagens by 'blue cotton' and Ames method using Salmonella typhimurium was used. The results were as follow; 1. The average revertant colonies of the Chun-gye stream on TA 98 was 120/plate and TA 100 was 267/plate. 2. The average revertant colonies of the Joong-rang stream on TA 98 was l06/plate and TA 100 was 407/plate. 3. Chun-gye and Joong-range streams showed about the same mutagenic activities. 4. The mutagenic activity of treated sewage was higher than of untreated sewage. It is considered that, among the influent materials with Zimpro oxidation fluid, human feces and urine increased mutagenic activities.

Objectives : We conducted an investigation on 14 cases of brucellosis in Gyeongsangbuk-do during 2003-2004 to understand the source of infection and the transmission routes of brucellosis. Methods : The authors visited the each of the health centers and we examined the patients, their written epidemiologic questionnaire and the occurrence of bovine brucellosis. We visited the patients' living and work areas, and we examined their occupations, the date they developed symptoms, the progress of their symptoms, whether or not they were treated, their current status, whether or not they consumed raw milk and raw meat, and if their work was related to cattle breeding and the related details. We reviewed the results of the blood tests and medical records and we examined the cattle's barn. Results : There were 3 patients in 2003 and 11 patients in 2004. All of their brucella antibody titer exceeded 1:160. The patients' symptoms were fever, myalgia, malaise, chills and an influenza-like illness, but the clinical signs were absent on the medical records. Brucella abortus were cultured from 3 of the patients' blood samples. Conclusions : When the authors discovered the transmission routes, they were divided into 4 different sorts. The first route was related to cattle birth such that patients touched the calves or placentas that were infected with the Brucella species. The second route was related to performing artificial insemination on the cattle and the semen that was used for artificial insemination. The third route was due to the ingestion of raw meat and milk. The last route was due to sexual intercourse between the patients.
