Objectives: A field survey was conducted in a hog-raising industry in order to help develop personal protective equipment for workers which would secure the safety and the health of these workers. The attempt by this study will help enhance safety in the livestock industry and contribute to the advancement of the industry. Method: The study first selected a total of 111 workers from the hog-raising industry as research participants and designed a survey with questions on general characteristics, indoor and outdoor working environments, how the workers would in practice wear or purchase the working clothes, what needs to be improved in these new working clothes, how much the workers would be likely to accept the working clothes and protective equipment, and lastly, conditions of the communicable disease control overgarment. The collected data underwent frequency analysis and cross analysis with SPSS 21.0. Result: The research targets' average age was 50 years. Work efficiency by environmental factor was normal, but all age groups had experience of accidents (79.3%). Major wounded parts were under elbow and under knee. Protective equipment most commonly worn was helmet (83.4%), gloves (98.2%) and boots (99.1%), and satisfaction with them was normal at 3.41. Working clothing most commonly worn was old clothing (31.8%) and everyday wear (17.6%) and satisfaction with it was low. Considering the improvement of working clothing, they required attached pouches, elasticity and deodorization. The acceptability of improved working clothing was high at 69.2%. Conclusion: After problems have been addressed in relevant future research, what has been learned from the concerned study will be referred to as a useful basic reference when the relevant field works to develop high-quality working clothing and protective equipment for workers in the hog-raising industry.

Hyperlipidemia is a major predisposing factor of atherosclerosis and cerebrovascular accidents. In effort to develope a hypolipidemic drug from medicinal herb, We tested three prescriptions of traditional medicine for the lipid lowering effect on diet-induced hyperlipidemic rats. GyejI-Bokryung-Hwan, Ohyak-Sunki-San, and Shihoga-Yongol-Moryu-Tang were selected based on the comnon prescriptions for patients with hyperlipidemia-related diseases. Water extract from each prescriptions was made by the method used in the clinical setting, and administered intragastrically once a day, for 4 weeks. Fenofibrate and lovastatin were given by the same method as the control drugs. Blood levels of total cholesterol(TC), high density lipoprotein(HDL), low density lipoprotein (LDL), and triglyceride(TG) were measured before, 1, 2, 3, and 4 weeks after starting the drug administration. All of the traditional prescriptions did not show lipid lowering effect, while fenofibrate lower the blood cholesterol levels(TC;from 215mg/dl before to 182m41 at 4 weeks-point of drug administration, and LDL ;from 203mg/dl before to aut 161, and 163mg/dl at 3 and 4 week-point respectively). Oyak-Sunki-San increased the level of TC (from 283mg/dl to over 350mg/dl starting from the first week of drug administratin). Effects on TG variable in the cases of traditional medicines and control drug In conclusion, any of the three traditional medical prescriptions did not decrease the level of blood cholesterol.

SMRs (standardized mortality rates) for major diseases, accidents, cancer are considered in small areas of administrative units such as Eup/Myeon/Dong from years 2005 to 2008. Due to small sample issue in small areas, the precision of directly estimated crude SMR for each area can be low. In this study, we consider the HGLM (hierarchical generalized linear model) with MRF (Markov random field) to account for the spatial correlations among the small areas. The effects of covariates for cause of mortality by Dongs in Seoul and disease maps based on the estimated SMR are presented. The results suggest how we analyze and interpret the difference in mortalities by small areas such as Dongs by revealing the spatial patterns.

The neck of the talus is its most vulnerable and fragile segment, because of narrow diameter, devoid of hyaline padding and honeycombed internally by vascular channels etc. Talar neck fractures comprise 50% of all major to the talus. The majority occurs as a result of high-energy injuries, such as motor vehicle accidents or fall from a height. Anatomically, talar surface is covered mainly with articular cartilage and blood supply to the talus is very poor. So, complications, such as non-union, avascular necrosis and post traumatic arthritis, are frequent. The authors reviewed fourteen cases of talar neck fractures treated in our clinics from Jan. 1992 to Mar. 1997, and average follow-up period was over 15 months. The results obtained were as follows; 1. Patients' average age was 31.2 years. 2. The most common cause was traffic accident(9/14, 64%), and hyperdorsiflexion injury of the ankle was common mechanism of the fractures. 3. According to the modified Hawkins classification, type I was four cases, type II was nine cases, type III was one case and type IV was no case. 4. Hawkins sign of subcortical radiolucency was found in 64% (9/14) of the fractures. 5. Avascular necrosis was occurred in 21% (3/14) of the fractures(in two cases of type II fractures, and in one of type III). 6. According to the Hawkins criteria, four cases in type I, five in type II were an excellent result. Two cases, one in type II and one in type III were good result, and two in type II were fair. One in type II was poor result.

This article suggests the radionuclides which should be considered more important to the offsite consequence assesment during a nuclear power plant accident. For this purpose, the relative importance to the early health effects of released radionuclides on the major organs during the accident is estimated under the assumption of the same release fraction. The inventories of the 25 elements, 54 nuclides selected in the Reactor Safety Study are calculated by ORIGEN 2 code. The organs of interest in the estimation are G. I. track, bone marrow, thyroid and lung. The result shows the relative potential importance of radionuclides as follows: For G.I. track, Np, Ce, Ru, Y, and Zr are of importance in sequence, Np, I, La, Sr, Ba for bone marrow, I and Te for thyroid, Cm, Ce, Ru, Pu, Zr for lung. In addition to iodine and noble gases, therefore, the potential contribution of those nuclides listed above to the offsite consequences should not be overlooked for some accidents of particular sequence.

The obstructive factors of the smoothly running traffic are street improvement, major commercial buildings like department stores, the large markets, the stadiums, the concert buildings, a lot of steady cars for using parking lot. The accident of cost many lives and traffic congestion from these factors cause the result that it enables to pay the enormous expenditure socially and financially. For solving these problems, Japan adopts the Traffic Flagger System in 1972. This task has the effects of improving traffic flow in the traffic jam and mitigating risk of car accidents as leading pedestrians and vehicles thereby the task carries into effect in the area where the accident took place. Moreover, this security task is rapid growth after adopting and 59.6%(5,317) of the whole security company 8,924 in Japan based on December 2009 registered as the traffic leading security business. While South Korea is demanded of the measures about obstructive factors of the smoothly running traffic, it represents the limitation of the system and the safety management. Thus the current study suggests the we will analyze South Korea's actual condition and then discuss the law and education system for a realizable plan reached the public-Private cooperation for adopting Japan's Traffic Leading Security System.

The prevention of marine accidents has been a major topic in marine society and various policies and countermeasures have been developed, applied to the industries. In order to improve the navigational safety level in the coastal waterways, the navigational safety level must be evaluated from the mariner's perception of safety. So far as human beings are concerned, there are many types of fuzziness in the evaluation of navigational safety level. In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy integral suggested by Choquet to represent the fuzziness in the evaluation process. This paper aims to develop the method for this evaluation from the viewpoint of mariner's operational stress using the fuzzy measure and Choquet integral. In this paper, Korean coastal area is divided into 8 sectors and evaluated the priority for the needs of coastal VTS and navigational aids. The results are found in the order named Mokpo, Yosu, Pohang, Inchon, Busan, Geoje, Gunsan, Donghae coastal area.

The prevention of marine accidents has been a major topic in marine society and various policies and countermeasures have been developed, applied to the industries. The coastal VIS and navigational aids are considered as one of the effective methods to promote marine safety but they need relatively huge amount of budgets to build Thus prior to establishing these coastal VIS and navigational aids, it should be evaluated the navigational risk level in the coastal waterways from the Environmental Stress. So far as human beings are concerned, there are many types of fuzziness in the evaluation of navigational safety level. In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy integral suggested by Choquet to represent the fuzziness in the evaluation process. This paper aims to develop the method for this evaluation from the viewpoint of mariner's operational stress using the fuzzy logic and Choquet integral. In this paper, Korean coastal area is divided into 8 sectors and evaluated the priority for the needs of coastal VIS and navigational aids.

Speeding has been reported as one of the major causes for fatal traffic accidents in Korea. The resolution against this dangerous speeding comes to make the automated speed enforcement system an enforcement tool. The speed detection device, which measures speeds of each incoming vehicles using double loop sensors, requires high accuracy. The object of this study is to develop an accurate speed measurement algorithm using double loop detectors. Some important findings are summarized as follows: 1) It was found that speed measurement errors are caused by scanning rate, distance of two loops, irregular vehicle trajectories, multiple vehicles in detection zone. 2) A proposed algorithm using two signal set proved to reduce variance as well as mean of speed measurement. 3) A proposed filtering algorithm was effective to filter irregular driving vehicles and multiple vehicles in detection zone. A comprehensive field test of developed algorithm resulted in significant improvement of speed measurement accuracy.
