Abstract This study was attempted to evaluate and quantify the differences of physical fitness among 4 swimming events(free style, back stroke, breast stroke, butterfly). To determine whether the differences among them existed or not the following question was addressed, were winning athletes among the 4 swimming events physically different? When significant differences were found, efforts focused on describing and quantifying the differences. On the basis of results, it is planned to select some physical fitness batteries which could best discriminate the successful swimmers. The 5 physique factors and 6physical fitness tests as discriminators, such as hight, weight, chest girth, upper limb length, lower jump, reaction time, one-legged standing time, vital capacity. The subjects included 60 elite swimmers sample from Pusan swimmers Team. The speed computer programs were used for data analysis. The results as follows: 1. physique In height, the average of male butterfly athletes was 170.0±3.0cm and 161.0±3.8cm for female butterfly athletes. The result of ANOVA test showed a significance difference for both man and woman(P<.05). In body weight, there was a significance difference both in male butterfly athletes(67.0±3.4kg) and back strokes(70.0±8.1kg). In case of woman, there also was a significance difference(P<.001) in case of woman, there also was a significance difference(P<.001) in butterfly athletes(54.7±5.5kg). In chest girth, it showed a 95.6±3.1cm for male back strokers and 83.0±3.3cm for female. Both showed a significance difference(P<.05) in 74.6±1.5cm for male butterfly athletes and 72.0±1.4cm for female back strokers. In lower limb length, the significance difference was found in male, female butterfly athletes and female breasts strokers, female free style. In standing broad jump, both male and female free style section shoed a significance difference(P<.001). In whole body reaction time, there was a significance difference for both female back strokers in light (0.33±0.1sec) and man free style sprinters (0.27±0.02sec) in sound. Here, there also was a significance difference in back strokers. In one-legged standing time, male free style section showed an annual significance difference(42.3±22.6sec. on average). In vital capacity, difference on the level of P<.06 (5,307±411ml on average). This study was attempted to evaluate and quantify the differences of physical fitness among 4 swimming events(free style, back stroke, breast stroke, butterfly). To determine whether the diffemces among them existed or not the following question was adressed, werw winning atheletes among the 4 swimming events physically different± When significant differences were found, efforts focused on describing and quantifying the differences.

BACKGROUND: Recently in Korea, the import of agricultural products is rising due to the increasing amount of trade. Unregistered pesticides, allidochlor, propachlor, propham, cycloate, diallate and pebulate are widely used as pesticides for rice cultivation in foreign countries, while they are not registered in Korea. Therefore, the residue amount of imported agri-foods should be verified using the proper official analytical method for each of them that has not registered in Korea. METHODS AND RESULTS: This work was conducted to apply the official method of Korea Food & Drug Administration (KFDA) for determining multi class pesticide multiresidues in agricultural commodities. Brown rice and orange which have different characteristics as a matrix were selected as representative samples for residue analysis. The recoveries of cycloate, diallate and pebulate by GC/MS in fortified brown rice and orange with levels of 0.04~0.4 mg/kg were ranged from 82.8% to 110.3%. The quantification limits of three pesticides in brown rice and orange were 0.04 mg/kg. CONCLUSION: As a result, this method can surely be used as an official method for routine analysis of unregistered pesticides in Korea for imported agri-food.

Pest control is major problem in front of farmer worldwide, an enormous economic loss is observed due to pest every year. There are several chemical pesticides available for controlling agricultural pests. Studies have shown chemical pesticides can cause significant health risks to humans, contaminate water supplies, and to plant itself. To come through this problem, we previously developed some natural pesticides i.e. oak pyroligneous liquor, rice bran and phytic acid which were tested against Perilla frutescens rust disease. We found good pesticide capacity of these natural extracts, so we were veracious to know whether it has toxic effect or not for that we designed the present investigation. In the present study we have determined toxicity on the basis of fish survival assay, seed germination assay and mice feed assay. Briefly, a concentration of 50 and 100μg\ml of all pesticides were supplied in water of fishes for 96hrs. We have taken two kind of fishes for this experiment Misgurnus anguillicaudatus(10) and Cyprinus carpio(10). After completion of the incubation period number of dead fish were calculated. Simultaneously, we determined seed germination test on four types of seed Cabbage, Radish, Black beans and Red kidney beans. A number of 20 seeds in case of red kidney beans 5 seeds were kept in sterile Petri dishes bedded with layer of tissue papers (Kimtec) which were wet with autoclaved distilled water. Treatment of pesticides was done with a concentration of 50 and 100μg\ml for 48 to 96 hrs. The number of non-germinated seeds was counted after the incubation period. In the case of animal toxicity test we supplied pesticides in the drinking water of mice and they were kept under investigation of body weight and death of mice. The results obtained from fish experiment suggest no toxicity of oak and rice bran but at a higher concentration one fish was found dead. In the case of seed germination assay all the seeds were observed to be germinated at both concentrations for all pesticides. No decrease in body weight was found in mice experiment as well as all mice were live. In accordance with all data, we concluded that the use of Oak, Rice bran and Phytic acid as a pesticide is safe and effective especially in the case of Perilla rust disease.

Objective: Although the effects and safety of transcranial direct current stimulation (tDCS) treatment in depressive patients are largely investigated, whether the self-administration of tDCS treatment at patient’s home is comparable to clinic-based treatment is still unknown. Methods: In this single-arm, multi-center clinical trial, 61 patients with mild to moderate major depressive disorder were enrolled. tDCS treatment was delivered at the patient’s home once a day, 5 to 7 times a week for 6 weeks, and each session lasted for 30 minutes. The primary outcome was a total Beck-Depression Inventory-II score, and no concurrent antidepressants were used. Results: The remission rates in both Full-Analysis (FA) (n = 61) and Per-Protocol (PP) (n = 43) groups were statistically significant (FA: 57.4% [0.44−0.70], PP: 62.8% [0.47−0.77]; percent [95% confidence interval]). The degree of depression- related symptoms was also significantly improved in 2, 4, and 6 weeks after the treatment when compared with baseline. There was no significant association between treatment compliance and remission rate in both FA and PP groups. Conclusion: These results suggest that acute treatment of patient-administered tDCS might be effective in improving the subjective feeling of depressive symptoms in mild to moderate major depressive disorder patients.

<P>In this study, we evaluated the repeatability of scans of stone models and impressions of abutment teeth using a blue LED scanner and compared the findings between different abutment teeth types. For the stone models as well as impression of the canines, premolars, and molars, we generated 10 color-difference-maps and reports for each tooth type (n=10 per tooth type). One-way analysis of variance (ANOVA) and independent t-tests were performed to evaluate the repeatability of scans of the stone models and impressions obtained from a blue LED scanner. Our results indicate a high repeatability of scans of stone models and impressions of abutment teeth using the blue LED scanner and suggest a possible clinical advantage for scanning impressions of different abutment teeth types.</P>
