  • In university laboratories, areas of studies are becoming diverse and complicated according to the development of the industry. New forms of potential risk factors are increasing and they are unlike existing ones. In addition, many students are conducting various experiments in the laboratory. Therefore, they could be exposed to risk more often. Despite these risks, people do not recognize university lab safety activities properly and observe safety precautions. They are exposed to various laboratory accidents continually. In this study, we do not apply the present diagnosis method, checklist, but the safety assessment that is widely used in industry. Then we can find lots of hazard that checklist method could miss. This study will use the 4M and Hazard & Operability to design a new Laboratory safety assessments method.

  • This study was conducted at occupational health laboratories in Seoul and Gyunggi district area from December, 1999 to January, 2000. The main purpose of this study was to survey the actual condition of safety and health by questionnaire and checklist and to assess the performance of fume hoods and the airborne exposures to chemicals in the laboratories. The chemicals in the cabinet were not classified by hazardous properties and the compressed gases were not stored safely. The prevalences of laboratories having first aid kits, fire extinguishers, and safety showers were found to be 18%, 55%, and 9%, respectively. Most laboratory workers were not educated for safety and health. Also, there was no performance evaluation for hazards and risks. The fume hoods in laboratories had not been annually inspected by checklist and the face velocity had been checked more than one time in the previous year for only 18% of them. Five percent of fume hoods had the face velocity more than 4.0 m/sec and 17% had no capture performance. Detected organic solvents were methylenechloride, acetone, ethylbenzene, isopropanol, xylene, methylisobutylketone, trichloroethylene, and toluene. The concentrations of organic solvents were much less than the occupational exposure limits proposed by the Ministry of Labor in Korea. This study showed that the actual condition of safety and health was not appropriate for laboratory workers. It is recommended that laboratory workers should be educated for the treatment and storage of hazardous chemicals and compressed gases to improve the working environment of the occupational safety and health laboratories.

  • The purpose of this study was to explore the care needs of family-caregivers caring for patients with a CVA and the level of self care of the patients. The subjects for the study were 112 patients with a CVA and their caregivers. These patients were seen in a hospital or out-patient-department(OPD) at two oriental medical hospital in Jeonbuk province. The survey instruments used in this study were Kang's ADL checklist for self care of patients and Kim's Likert-style checklist for care needs of family-caregivers to patient with CVA. The survey was conducted from July 4 to August 30, 1999. Internal validity by calculation of Cronbach's alpha was 0.95, which was regarded as high. The survey results were analyzed using the SPSS program, with percentages, means, t-test, ANOVA and Pearson's correlation coefficients. The results of this study are as follows : 1. The level of self care for patients with a CVA was : 1) complete dependence(M=14.9, 13.1%), 2) complete independence(M=23.6, 20.9%), 3) incomplete independence(M=23.9, 21.0%), 4) incomplete dependence(M=26.6, 25.0%), 5) dependence and independence(M=23.0, 20.0%). The items for which there was a high level of self care were : 1) drinking(M=3.62), 2) eating (M=3.25), 3) position returning(M=3.18) : and the items for which there was a low level of self care were : 1) ascending and descending stairs(M=2.08), 2) walking(M=2.47). 3) putting on and taking off trousers(M=2.55). 2. The mean score of the sum of the care needs of the family-caregivers was : 1) need for immediate care and help: 2) need of the way to communicate with patient: 3) need for education and assistance related to physical functional level: 4) need to be informed about the disease, treatment and care: 5) need for social support and consultation: 6) need for appreciation: 7) need for management of nursing problems related to immobility. The highest meed factor was the need for immediate care and help(M=3.47): and lowest need factor was the need for management of nursing problems related to immobility(M=2.80). 3. There were significant differences between the level of care need and general characteristic of the caregivers, there were family-caregivers age(P=0.001), marital status (P=0.276), occupation (P=0.006), monthly income(P=0.000), Patient's relationship to caregivers(P=0.004) and health(P=0.000). 4. There were significant differences between the level of self care and general characteristic of the patients, there were patient paralytic condition(P=0.01), blood pressure(P=0.01), and length of suffering(P=0.03). 5 There were significant differences between the level of care need and the general characteristic factors, which were CVA patient's blood pressure (P=0.05), problem of medical fee (P=0.05). 6. There was significantly correlation with the family-caregivers care need and the level of self care in the CVA patient(r=0.300, P=0.000). As a result, need to promote the level of self care in patients and to meet the care need of family-caregivers for more efficient nursing of CVA patients, is emphasized. Therefore more study is needed on an efficient way to provide rehabilitation and quality nursing interventions for family-caregivers and patients with CVA.

  • The goal of this study is to analyze an effect of productivity elevation. For the goal, the various methods of the productivity elevation were suggested and the system improvements were conducted. The S company was established in Ban-Wol Industrial Complex, Ansan-City, Kyonggi-Do on 2007. The company was hiring 22 employees. The main manufactures were heavy duty equipment parts and the amount of sale was two billion won on 2008. Problems which the company faced were ambiguous production target management and materials loss. To solve the problems, NCT work improvement and automatic welding were induced. There were steel saving of 3,780,000won/month and man-hour saving of 144,000won/month by redesign of the steel sheet for the NCT steel job. Also, changing from handwork to automatic welding, the man-hour saving for the welding job was 320M/H and saving of 4,225,600won/month. The others of systematic improvement for productivity elevation were usage of jig and daily equipment checklist.

  • Purpose: Mobile cranes are machines that contribute to high mortality, and the High Risk Factor (SIF) information, which analyzed 2,574 accidental deaths in the construction industry in the past 6 years (2016~2021), resulted in a total of 61 mobile crane accidents. Despite safety measures in the field, it is not used properly. In this study, we present standard risk assessment indicators that contribute to accident prevention. Method: Through expert interviews, fatal accident case analysis, field analysis, and literature research, we present the standard risk assessment index method of the 4M risk assessment method. Result: As a result of analyzing the risk assessment of eight sites, it was concluded that it cannot make a significant contribution to disaster prevention and should be applied as an improvement measure of the Standard Risk Assessment Index Law. Conclusion: Switching to the standard risk assessment index method at construction sites has been proposed to make it easier for health and safety personnel and workers to use, contributing to the reduction of accidents.

  • Following natural disasters, there is a need to develop temporary housing through the rapid installation of mass-produced prefabricated housing. This study has developed a model construction manual for prefabricated temporary housing installable in underground spaces. First, the temporary housing prototype was drawn based on opinion poll results from earlier studies. $4.32m^2$ was calculated as the basic unit of the temporary housing living space for one person. Units included panel type, box type and mixed-type, for a variety of field conditions and scales. In order to enable space expansion and movement desirable to the user, the prototype was combination of panel and box types. The drawn prototype was utilized as the basic design template for producing prototypes and for the manual. Second, the possibility of utilizing subway stations as temporary housing was verified through the production of the prototype, and the construction process was summarized in the manual. The manual was developed in the form of a checklist to provide a guideline for users to build with prefab materials.
