This study was carried out to investigate the current state of occupational health management and characteristics of employees working in small-scale-enterprises (SSE) employing less than 50 workers. Samples were chosen among the two thousands employees working in 838 factories where located in Youngdungpo-Ku, Seoul, Korea. The study results were as followed: 1. Most factories investigated in the study were manufactures (68.6%) which were established in 5 to 10 years ago (29.2%), employing less than 5 workers (72.9%) and registered in accident compensation insurance (23.0%). 2. Health screening was undertaken in 24.9% workplaces for periodic health examination and in 1.5% for special health examination. Environmental monitoring was done in 3.3% factories. Very few factories displayed Material Substance Data Sheet (MSDS) in 3.1% among the total factories. 3. Workplaces usually had their own toilets in 75.9% and washing basin in 58.6% as types of sociowelfare facilities. 4. Employees responded in the study were mostly in the range of age from 30 to 39 in 34.7%. male in 84.8%. the married in 70.3%. manual workers in 42.0%. mostly working regularly 51 hours per a week in 48.2% and earned 710.000 Won to 1.000.000 Won per month in 35.0%. Medical utilization for employees were covered by factories sponsored medical insurance in 12.7% and by provincial sponsored medical insurance in 83.4%. 5. Two point six percents of employees were suffered by diseases. The health complaints indicated were mainly digestive problems in 46.7% and hypertension in 24.4%. 6. Employees wore personal protective equipments for work such as gloves in 48.1%. safety shoes in 30.5%. ear plug in 5.5% and mask in 6.9%. Based on the results of study, we recommend that various types of occupational health management should be developed according to workplace working condition of each factory. In addition to the development of occupational health strategies. we think that it is more important to monitor and to allocate how effectively they operate each other on the basis of longitudinal continuity. Besides, we would like to insist that these all management effort should be focused on prevention of disease and occupational health education of employees.

This study was performed to find out the patterns of Listeria spp. contamination during Kimbab preparation at the specialized restaurants. Samples were collected from ingredients, containers, equipments, and environments from two Kimbab restaurants from July through September, 2004. Isolation rate of Listeria spp. was $43.2\%$ among 264 samples. Strains isolated were Listeria innocua $35.9\%$, L. murrayi $6.8\%$, and L. grayii $0.3\%$. No L. monocytogenes was detected. Contamination level of ingredients, containers, equipments, and Kimbab sampled during afternoon was all significantly higher than the samples collected during morning(P < 0.05). The most influencing factor of contamination was improper handling or no disinfection procedures during Kimbab preparation. Safety controls are recommended as follows; prevention of cross-contamination during ingredients Preparation, temperature control for ingredients and Kimbab during holding, cleaning and disinfection of chopping boards and knives during preparation processing, and frequent changes of disposable gloves. Kimbab restaurants should recognize the importance of safety control using the Good Hygienic Practices.

The objective of this study was to evaluate microbiological Quality of HACCP application in elementary school foodservice operations. Microbiological Quality of utensils and non-heated foods such as salad was measured two times at five elementary schools in Daegu. The two experimentations differed in that after the first experimentation employees were educated and trained on HACCP based sanitation standards with a goal of improving microbiological Quality of foodservice. Microbiological Quality, time, and temperature were evaluated at three critical control points (CCPs): washing and disinfecting, personal hygiene and non-cross contamination. Micro-biological Quality was assessed using 3M petrifilm to measure total plate count and coliform group. The first experimentation showed low microbiological Quality due to cross contamination of utensils and cooking gloves; high microbiological count of the garlic, powdered red pepper, and ginger; and not thoroughly washing and disinfecting vegetables. In the second experimentation, microbiological Quality was greatly improved by washing and thoroughly disinfecting raw ingredients and utensils, and using good personal hygiene. However, microbiological Quality of seasonings was still low. Immediate corrective actions were required in one of the foodservice operations that was assessed. These results strongly suggest that foodservice operations should address non-heated food Quality. It is essential to measure microbiological Quality regularly and continually train and retrain employees on hand washing and disinfecting raw ingredients. Further studies are needed to determine whether pathogens are present in raw vegetables and seasonings.

This study was conducted to investigate the thermoregulatory behavior of young males in terms of self-identified thermal tolerance. We recruited 436 male students from Seoul ($24.0{\pm}4.6yr$ in age, $175.3{\pm}5.5cm$ in height, $70.1{\pm}10.6kg$ in body mass, and $23.0{\pm}2.7$ in BMI) in accordance with four types of self-identified thermal tolerance: 1) tolerable of both cold and heat, BCH (N=15); 2) heat tolerable only, HTO (N=118); 3) cold tolerable only, CTO (N=162); and 4) neither cold nor heat tolerable, NCH (N=141). The questionnaire consisted of 55 questions regarding preference to cold or heat environment, seasonal thermoregulatory behaviors including clothing habits, seasonal sleeping environments, health care/physical fitness, and anthropometric items. The results showed that: 1) BCH preferred less auxiliary heating devices, gloves/hats, or thermal underwear in winter and had very few experiences with cold/heat injuries or catching a cold, whereas NCH showed the opposite behavior and experiences as BCH; 2) thermoregulatory behaviors were not symmetrical between summer and winter. Most male students preferred cold beverage/foods to using cooling devices to lower body temperature in summer, whereas auxiliary heating devices were preferred to warm beverage/foods to maintain body temperature in winter; 3) thermoregulatory behaviors of NCH had more items in common with HTO than CTO, while the behaviors of BCH were more closely related to CTO than the behaviors of BCH were more closely related to CTO than HTO. Overall, we confirmed that thermoregulatory behaviors were apparently classified by self-identified thermal tolerance, and such behaviors could be adjusted by improving cold or heat tolerance.

This study was aimed to assess microbiological contamination level of Liriope platyphylla farms (A, B, and C) located in Cheongyang, Chungnam province. Specimens sampled from those farms and L. platyphylla tuberous roots were assessed for sanitary indication bacteria such as total aerobic bacteria, coliforms, and Escherichia coli and pathogenic bacteria such as Escherichia coli O157:H7, Listeria monocytogenes, Salmonella spp., Staphylococcus aureus and Bacillus cereus, quantitatively and qualitatively. As a result, those farms are not contaminated by E. coli O157:H7, L. monocytogenes, Salmonella spp., at all. And S. aureus was only found qualitatively from workers' gloves at a farm. As a whole, those farms (soil, harvest container, harvester, cleanser, washing water and tray) were maintained in a low level of microbiological contamination. However a cleanser was contaminated by coliforms ($4.35log\;CFU/100cm^2$), and it is required to improve farm hygiene. Microbiological contamination level of L. platyphylla tuberous root was decreased in the postharvest process including washing and drying.

Thirty six patients, female 21(58.4%), male 15(58.4%), with centipede bite visited emergency room of Gimcheon Medical Center, from September 1998 to August 1999. The number of patients accompanying the seasons were increased once in June and were high in August and September; peaked in September, which conforms to the habitude that centipede likes the warmer climate. Frequency accompanying the time was high after sunset(from 6 p.m. to 6 a.m. next morning) than before sunset, which conforms to the habitude that centipede is nocturnal. Distribution of the bite sites was finger(30%), neck(28%), foot(25%) and hand(14%) as same as the previous researches showed. In case of finger and hand, patients got bitten while they were wearing gloves or doing works; foot, wearing shoes. They got bitten the neck while sleeping. Among the localized symptoms were localized pain: 36 patients(100%), swelling: 36 patients(100%), erythema: 26 patients(72.2%), paresthesia: 5 patients (13.9%). Systemic symptoms were dizziness 2 patients(5.6%) and nausea 1 patient(2.8%). Mostly the localized pain was improved within 48 hours, swelling in 48 hours and within 72 hours in case of paresthesia. Systemic symptoms such as dizziness and nausea were improved within 24 hours. Treatment and prognosis of scolopendra have similarity in many countries. We suggest that Korean standard treatment manual is needed so that the localized symptom, systemic symptom and external wound can be cured soon.
Objectives : This study was to study dental hygiene department students' management of infection and their attitude toward infection. Methods : This study was conducted from August 24, 2009 to September 20, 2009. 269 sophomore and junior college students enrolled in the department of dental hygiene from schools located in Gyeonggi-do and Gangwon-do participated in the study. A self-administered questionnaire survey was conducted. Results : 1. As for dental hygiene department students' recognition of the causes of infectious diseases, 80.7% of the respondents said hepatitis B was the infectious disease highly likely to occur in laboratories. 35.3% was correct about the antecedent variables of infection in the workshop, 24.9% about the oral symptoms of HIV and 18.6% about the diseases induced by HBV. The recognition rates were generally low. 2. About whether the respondents ask patients questions about infectious diseases, 80.7% of them answered Yes, but only 56.2% of them said they do so every time, and 17.8% of them said they never do so. 3. As far as washing hands to prevent infectious diseases is concerned, 97.4% of the respondents said hand washing helps prevent infection. 72.5% of them said they wash their hands every time before they practice on a patient, while 84.0% of them said they washed their hands after the lab practice. 90.7% said they use liquid soap containing anti-microbial agents, and 81.8% of them said they use paper towels. 4. With regard to protective gear for prevention of infectious diseases, 98.9% of the respondents said it is desirable to use disposable protective gear for each patient. When it comes to what they actually used as protective gear, 91.1% said aprons, 89.2% gloves, and 87.7% masks. However, a low percentage of the respondents actually use goggles and replace masks when they got damp, 11.2% and 24.2% respectively. Conclusions : As for treating the surface of equipments to prevent infectious diseases, most of the respondents exhibited a high recognition rate. Relative fewer respondents actually treat the surface of equipments than those respondents who are aware of the need to do so. A high percentage of the respondents also said they use alcohol sponge to treat the surface of each equipment in order to prevent infectious diseases.
The purpose of this study was to evaluate the microbiological quality, and to assure the hygienic safety of the food production in the university food service facility located in Seoul in accordance with the Hazard Analysis Critical Control Point(HACCP) concepts. In the hygienic state assessment of kitchen, it has revealed that it was very important to remove water from the kitchen floor and to establish standard method for disinfection of cooking utensils. And foodservice workers were required to have training program for the safe handling of food and utensils since they did treat food without hygienic gloves. The kitchen layout had to be improved because the near distance of table with heating unit and shelf might cause the growth of microorganisms when prepared food was kept on the shelf. In terms of the timetemperature measurement and microbiological quality assessment during each of the food production phases, most of sengchae (raw vegetable dish) and namul (cooked vegetable dish) were treated within danger zone for food safeness ($5~60^{\circ}C$). It has shown that the microbiological quality of raw materials was very much inferior at the time of receiving based on the TPC($10^{5}~10^{7}$), coliform($10^{3}~1O^{6}$), which was not acceptable level(TPC:$10^{6}$, coliform:$10^{3}$) suggested by Solberg. Microbiological growth has increased in the both of sengchae and namul considerably during most of food production phase. Therefore, it is extremely important to reduce holding and serving time and to avoid treating food within the danger zone for food safeness. In addition, the prevention of cross-contamination during mixing the ingredients with improper equipments and with insanitary treatments by workers was also important to keep the food safety in this speciqic university foodservice facility.
Produce, including leafy vegetables, has been implicated in several outbreaks of food illness. To evaluate microbiological safety of lettuce and it's cultivation area, a total of 147 samples were collected from lettuce farms and post harvest facility at Icheon, Gyeonggi province. The collected samples were assessed for presence of sanitary indicator microorganisms (Aerobic plate count, coliform count, Escherichia coli) and foodborne pathogens (Escherichia coli O157:H7, Salmonella spp., Staphylococcus aureus, Listeria monocytogenes, Bacillus cereus). The population of APC was over 4.0 log CFU from most of the samples. While the numbers of APC, and coliform of lettuce at 62 days after transplanting were 4.18 log CFU/g, and 1.00 log CFU/g, respectively, those of 10 days after transplanting were 5.37 log CFU/g, and 2.87 log CFU/g, respectively. B. cereus was highly detected from soil and balance which were contaminated with 3.5 log CFU/g, and 2.6 log CFU/100 $cm^2$, respectively. The number of E. coli recovered from gloves was 3.5 log CFU/hand. However, E. coli O157:H7, Salmonella spp., and L. monocytogenes were not detected. These data suggested that risk management system should be introduced to lettuce farms to enhance safety of lettuce.

Objective : The aim of this study was to investigate the status of infection for infectious diseases and infection control in occupational therapy. Methods : This study was implemented through the survey composed of the status of infection for infectious disease and the infection control and awareness of the infection control. The duration of survey was a month, June, 2016. 111 occupational therapists in 23 room of occupational therapy completed a survey. Results : 34.8% of occupational therapy room experienced the infectious diseases. This study showed the occupational therapists have high performance in almost items of infection control. But the occupational therapist showed the low performance in the items including 'Washing hands over than 15 seconds', 'Washing hands before and after wearing gloves', 'Wearing mask during treatment', 'Throwing away mask after using' and 'Washing your uniform separate from other cloths'. Almost occupational therapists think infection control is important and the education for infection control is needed in occupational therapy. But most of the education is implemented in only medical institution. Conclusion : To improve performance in infection control, individual effort of occupational therapists and institutional strategies are needed. This study will use as basic data for the education about infection control aimed at the occupational therapists.
