Objectives: The aim of this study was to assess exposure to VOCs and PAHs and the health effects on volunteers who participated in an oil spill cleanup in Yeosu. Methods: Atmospheric VOCs were evaluated in the vicinity of the accident site and questionnaire surveys were conducted to identify personal characteristics and acute health symptoms of clean-up workers seven days after the accident. The levels of metabolites of VOCs (t,t-MA, HA, PGA, MA, MHA) and PAHs (2-NAP, 1-OHP, 2-HF, 1-HPH), oxidative stress markers (TABARS, 8-OHdG) in the urine of workers were analyzed. Their correlation was determined by multiple regression analysis with SAS ver. 9.4. Results: Although the concentration of atmospheric VOCs in the residential areas were low at the time of survey, the levels of VOCs and PAHs metabolites in clean-up workers were higher than those in the control group after clean-up activities. The levels of urinary VOC and PAH metabolites were significantly increased after clean-up compared to those measured before participation. The thiobarbituric acid reactive substance (TBARS) concentrations were also increased and showed significant correlations with those of metabolites of benzene. Conclusion: This study shows that oil spill clean-up activities affect exposure to VOCs and PAHs and the health of clean-up workers. The results suggest the need for check-ups of participants in oil spill cleaning work.

Depression is one of the most common psychologic disorder and dealt as a major public health concern. School students have heavy school work loads and stress from various evaluations representing school performance. In this study, to examine the effect of school performance and stress on depressive symptoms, we assessed the frequency of risk factors for depressive symptoms among 2,717 high school students. From April 2001 to May 2001, using a self-reported questionnaire, we collected data on the frequency of occurrence of depressive symptoms and potential risk factors for depressive symptoms. Depressive symptoms were measured using Center Epidemiologlc Studies Depression (DES-D) index. Thirty-seven percent of high school students reported having high depressive symptoms for a week Female students had a higher prevalence of depressive symptoms than males (OR=1.44, 95% CI 1.22-1.70). In a multiple logistic regression model, we found that good perceived school performance (OR=0.43, 95% CI 0.31-0.60) had a negative association with depressive symptoms. On the contrary, we also found that stress from school performance (OR=2.03, 95% CI 1.69-2.44) associated with high depressive symptoms. In conclusion, high school students had a relatively high prevalence of depressive symptoms. Students with stress from school performance had the higher risk for depressive symptoms.

Helminthological parasites for inhabitants in Boeun-Gun, Chungbuk province were survyed. Total infection rate was 21.4% and helminth ova of-seven species were observed: Clonorchis sinensis 11.7%, Metagonimus sp. 7.0%, Echinostoma hortense 2.7%, Taenia sp. 2.3%, Ascaris lumbri-coides 0.8%, Trichuris trichiura 1.6% and Enterobius vermicularis 3.5%. Infection rate of food-transmitted helminths (C. sinensis, Metagonimus sp. E.hortense, Taenia sp.) was 76.4% (42/55), soil-transmitted helminths (A.lumbricoides, T. trichiura) was 7.3% (4/55), contageous helminths(E. vermicularis) was 16.3% (9/55). Multiple infection rate was 30.9% and most of them were limited in snail-transmitted helminths(C.sinensis, Melagonimas sp., E. hortense). Infection rate of male (18. 3%) was higher than those of female (3.1%). Intensities of C.sinensis and Metagonimus sp. were light or moderate, showed 530 and 444 by mean E.P.G. respectively. In this survey, we newly found the small endemic areas of E.hortense, which was previously reported sporadically in Korea other than in Chungbuk province.

As the number of the elderly increases, concerns about senile dementia and serious game for dementia are growing. The purpose of this study is to explore the types of attitude toward senile dementia. To identify public attitudes toward senile dementia, we conducted Q methodology. A Q set of potential public attitudes toward senile dementia was identified through literature review. From this, 52 potential public attitudes toward senile dementia were identified. Twenty subjects ranked these explanations as possible public attitudes. The attitudes toward senile dementia were classified as 4 types : 'type1 : idealistic & expectant', 'type 2 : aversive & defensive', 'type 3 : active & realistic', and 'type 4 : responsible & compensatory'. This study revealed that people have different explanatory frameworks for the attitude toward senile dementia.

Accurate classification of water area is a preliminary step to analyze the flooded area and damages caused by flood. This is essential process for monitoring the region where annually repeating flood is a problem. The accurate estimation of flooded area can ultimately be utilized as a primary source of information for the policy decision. In this paper, flooded areas was classified using 1:25,000 land use map and a RADARSAT image of Ok-Chun and Bo-Eun located in Chung-Book province taken in 12th of August, 1998. Then we analyzed the flood area based on GIS. A RADARSAT image was used to classify the flooded areas with slope theme generated from digital elevation model. In processing on a RADARSAT image, the geometric correction was performed by a backwardgeocoding method based on ephemeris data and one control point for near real time flood area analysis.

The purpose of this study is to verify the cognitive theory of Multimedia learning in a Smart Pad environment. Specifically, the viability of the multimedia principle and individual difference principle was tested for this study. To accomplish this, participants were divided into two groups based on their prior knowledge level (high/low), and members of each group were given one of two Smart Pad based programs, one text-based and the other text and image based. Results indicate that the use of images and the interaction between image use and prior knowledge did not have a significant effect on cognitive load levels. However, there were significant effects on learning achievement. This study implies that when developing Smart Pad based learning content, the small screen size compared to PC monitors, types and functions of images, and learning objectives should be considered.

Social unrest from retaliatory crimes is increasingly becoming problematic. Recently, there was an accident involving a suspect who went to a hospital and committed acts of retaliatory violence 11 times. This person's reasoning was that he was imprisoned due to the hospital's reporting to the police. He was consequently arrested in Boeun Choongbook on December 27th 2014. Accidents like this one take place frequently around our surroundings. There are regulations and systems in place. Nevertheless, similar cases that continue to take place makes us wonder if criminal judicial systems work well. Lukewarm responses to retaliatory crimes is not only threatening social security, but also placing fears in the minds of ordinary citizens. If retaliatory crimes take place, most citizens become apprehensive about criminal judicial activities of the police and mistrust for criminal judicial system. This at times discourages people from reporting incidents and could eventually increase crime rate and cause various social problems. Even though there are legal and systemic control measures, retaliatory crime is an increasing trend. This study is going to examine tendencies of internal retaliatory crimes and discuss legal-systemical responses.

Purpose: The purpose of this study was to identify the effects of an exercise program on muscle strength, Activities of Daily Living (ADL), health perception, and depression among post-stroke elders. Methods: Nonequivalent control group design with pretest and posttest was used. A total of 23 post-stroke elders who met inclusion criteria were recruited. Muscle strength in upper and lower extremities, ADL, health perception, and self-rated symptoms of depression were measured. The exercise program consisted of deep breathing, range of motion, and muscle strengthening exercises using Thera-band, 30~40 min/day, three days a week, for 12 weeks. Results: Muscle strength of right shoulder (U=11.50, p=.001), right leg (U=13.50, p=.002), and health perception (U=24.00, p=.010) in the experimental group was significantly higher compared to the control group at 12 weeks of post-intervention. Depression scores were significantly lower in the experimental group compared to the control group at 6 weeks (U=28.00, p=.021), at 12 weeks (U=22.00, p=.006) of an exercise program. Conclusion: By applying this program, post-stroke elders showed increases in muscle strength and a decrease in depression as well as improvement of health perception. Further study is needed to verify the effects of the exercise program on cardiovascular physiologic variables through long-term follow-up.
