This research investigated the sensory processing ability and selected subjects who had sensory processing problems, and divided the subjects into an experimental group and control group. The experimental group was educated with sensory processing intervention on the activities of daily living to determine its influence on the quality of life. The study was based on 230 university students with similar majors in 3 universities of Chungcheong area in the beginning of May, 2013. From here, 32 subjects who had issues with their sensory processing ability were selected. The 230 students were given a survey on the quality of life, individual characteristics, and sensory processing ability. Later, the 32 subjects who had problems with their sensory processing ability were divided into an experimental group and control group. The control group performed sensory processing intervention, whereas the control group did not. After the sensory processing intervention method for 6 weeks, the quality of life was re-evaluated. As a result, the total score of the quality of life after intervention was 98.69 in the experimental group and 84.81 in the control group (p=0.001). The physical score was 16.43 in the experimental group and 14.64 in the control group (p=0.008). The psychological score was 14.71 in the experimental group and 11.75 in the control group (p<0.001). The social score was 14.67 in the experimental group and 13.17 in the control group (p=0.032). The environment score was 14.66 in the experimental group and 12.34 in the control group (p=0.006). The experimental group showed a significant increase in all areas of the quality of life, whereas the control group did not. Through this result, it can be seen that a sensory processing intervention method in daily life can increase the quality of life for subjects with problems in sensory processing ability. Overall, it will be necessary to apply a treatment of various sensory intervention programs for adults and promote a better quality of life.

The purpose of this study was to analyse the properties of leisure activity and the life satisfaction in the case of Korea Science Academy(KSA) students and Min Jok Leadership Academy(MLA) students. The participants consisted of KSA students(male:122, female:44) and MLA students(male:71, female:113) with voluntary consent. We had achieved the following results. 1) For leisure activity, KSA and MLA's male students showed the highest ratio for participation in the sports, KSA's female students in the taste-culture activity and MLA's female students in the sight-seeing. 2) The response showed that stress treatment was the principal reason of leisure activity's need. 3) Over 50% of the male students were satisfied with the present leisure activity but 12% of the KSA male students and 14% of the MLA female 14% answered to the "unsatisfactory" or "very unsatisfactory". 4) Mental stress treatment showed the highest ratio in the response to the question asking the principal straight motive of leisure activity. 5) 75$\sim$80% students considered the leisure activity as an important means to maintain health and physical fitness. 6) Though most students participated in the activities with friends, 30% of the students answered that they participate by themselves. 7) It was shown that 51% and 40% of KSA male and female students, 40% of MLA male students and 48% of MLA female students participated in leisure Activity planlessly. 8) The average leisure time of the most students was less than 2 hours a day and Male students were observed to have more leisure time than female, and KSA students to have more time than MLA students. 9) In weekdays, KSA's male students enjoyed mostly the sport for leisure activity, but taste-culture activity showed the highest ratio in the case of MLA students and KSA female students. 10) In the case of male students, 38% of KSA and 54% students of MLA did not play computer game at all, and 70% of the female students in total did not play computer game. Also, the proper control-method was in need because the result showed that KSA's male students spent more time in playing computer game than MLA's male students did. 61% of KSA female students and 53% of MLA female students answered that they did not play compute game at all during weekends. Whereas It showed that 26% of KSA male students played computer game over 3 hours during weekends. 11) The biggest reason for being unable to participate in the leisure activity was the insufficiency of time due to homework or studying for quiz. The laziness also showed high percentage of 19$\sim$25% varying between the groups. 12) The life satisfaction of KSA male students was visibly higher(p<.05) than that of MLA male students but the significantly difference wasn't shown in the case of female students.

PAHs(Polycyclic Aromatic Hydrocarbons) compounds may enter into the marine environment in a number of ways, and PAHs in coastal area and estuary adjacent to urban area and industrial activities region are mainly introduced into marine environment via atmosphere or river. The field surveys to evaluate the pollution of PAHs in rivers of Jinhae bay were carried out in August, 2008. The water samples collected from seven main rivers and Deokdong WWTP(Waste water Treatment Plant) which lead to Jinhae bay. 16 PAHs which had been selected as priority pollutants by EPA were analyzed. The range and mean of dissolved Total PAHs concentrations in the rivers and Duckdong WWTP that lead to Jinhae bay were shown to be 9.79~128.25(mean 36.94)ng/L, while the range and mean of Total PAHs concentrations in SPM(Suspended Particulate Matter) were shown to be 1,81434~8,893.37(mean 4,657.73)${\mu}g$/kg dry wt. The dissolved Total PAHs and Total PAHs in SPM were shown to be high concentrations in the Semhocheon which leads to Masan bay that is the most polluted area of Jinhae bay, while those were shown to be low concentrations at rivers which lead to the west area of the bay. The ranges and means of the loading fluxes from rivers and Duckdong WWTP were calculated at 0.06~12.05(mean 1.86)g/day for dissolved Total PAHs and at 0.12~16.00(mean 2.41)g/day tor Total PAH in SPM. The loading flux of Total PAHs from Duckdong WWTP was shown to be the greatest, occupying more than 80% of Total loading flux from all rivers and WWTP to Jinhae bay. The composition patterns of PAHs compound by the number of benzene ring between dissolved PAHs and PAHs of SPM were different each other. Low molecuar weight PAHs of dissoloved compounds were in high concentration, while high molecular weight PAHs of SPM were in high concentration. These results were due to physical and chemical characteristics of PAHs and were similar to those of other studies. The total PAHs concentrations of dissolved and SPM in this study are lower than those of other studies. The extent of PAHs pollution appeared to be not serious in reverine waters of Jinhae bay.

Geochemical data of soil and water samples were presented in order to assess the environmental impart for drinking water sites. Microscopic observation of rock samples and physical and chemical analysis of soil and water samples were undertaken. The geology of study areas are classified into three groups such as granitic rocks, meta-sedimentary rocks and sedimentary rocks. Enrichment of heavy metals derived from those rocks is not found in this study areas. Soils were analyzed for Cu, Pb, Zn, Cd and Cr using AAS extracted by HNO$_3$+HClO$_4$ and 0.1 N HCl. Heavy metal concentrations in soils are within the range of those in uncontaminated soils. In comparison of metal contents extracted by 0.1 N HCl and HNO$_3$+HC1O$_4$, less than 10% of the heavy metals are present in the exchangeable fraction. In particular, an pollution index has been proposed to assess the degree of soil contamination. Pollution index in soils are between 0.03 and 0.47 therefore, soils are not polluted with heavy metals. Deep groundwaters within granitic rocks have been evolved into Na$\^$＋/-HCO$_3$$\^$-/ type, whereas other deep groundwaters evolved into Ca$\^$2＋/-HCO$_3$$\^$-/ type. The predominance of Na$\^$＋/ over Ca$\^$2＋/ in deep groundwaters within granitic rocks is a result of dissolution of plagioclase, but for sedimentary and meta-sedimentary rocks, dissolution of calcite is a dominant factor for their hydrogeochemistry. The pH, conductivity and contents of the most dissolved ions in the water increase with depth. Shallow groundwaters, however, are highly susceptible to pollution owing to agricultural activities, considering the fact that high contents of nitrate, chloride and potassium, and high K/Na ratio are observed in some shallow groundwaters. In a thermodynamic approach, most natural water samples are plotted within the stability fields of kaolinite and smectite. Therefore, microcline and other feldspars will alter to form clay minerals, such as kaolinite and smectite. From the modelling for water-rock interactions based on mass balance equation, models accord well with behavior of the ions and results of thermodynamic studies are derived.

The purpose of this study was to compare the anthropometry, blood pressure, blood lipid levels, and nutrient intakes in three groups: a group with an impaired fasting blood glucose (IFG) condition (62 males and 30 females); a group with normal blood glucose (73 males and 50 females); and a group with diabetes mellitus (DM) (79 males and 49 females). In male subjects, body mass index (BMI) and obesity index values were significantly higher in the IFG group than in normal and DM groups, but waist/hip ratio (WHR), systolic blood pressure, and diastolic blood pressure were not significantly different from those of the DM group. In female subjects, there was no difference in body weight, BMI, obesity index and WHR values between the IFG and the DM groups. The prevalence of obesity in the IFG group (males 43.6%, females 76.7%) was the highest among the three groups. The percentage of high SBP (40.0%) and high DBP (52.0%) in male subjects of the IFG group was significantly greater than in the DM group or the normal group. In the male subjects, the serum triglyceride concentration was significantly higher in the DM group than in the normal and IFG groups. There was no difference in various nutrient intakes(energy, carbohydrate, protein, fat, calcium, iron, vitamin A and cholesterol) among the three groups. In male subjects, the percentage of energy intake from alcohol was higher in the IFG group (7.0%) than that of the normal (4.5%) and the DM (5.6%) groups. The fasting blood glucose level had a positive correlation with WHR, TG, the athrogenic index and LDL-cholesterol/HDL-cholesterol. This study suggested that the IFG group had a higher obesity index, BMI, blood pressure and serum lipid levels (TG, cholesterol) than the normal or the DM group; furthermore, the IFG group had higher levels of alcohol intake and habits of taking unbalanced diets. Therefore, guidelines for IFG group should emphasize weight control, diet therapy, physical activities and regular balanced diets, in order to prevent diabetes in this group.

Objectives: Receive Operating Characteristic(ROC) curve with the area under the ROC curve(AUC) is one of the most popular indicator to evaluate the criterion validity of the measurement tool. This study was conducted to develop a standardized questionnaire to discriminate workers at high-risk of work-related musculoskeletal disorders using ROC analysis. Methods: The diagnostic results determined by rehabilitation medicine specialists in 370 persons(89 shipyard CAD workers, 113 telephone directory assistant operators, 79 women with occupation, and 89 housewives) were compared with participant's own replies to 'the questionnair on the worker's subjective physical symptoms'(Kwon, 1996). The AUC's from four models with different methods in item selection and weighting were compared with each other. These 4 models were applied to 225 persons, working in an assembly line of motor vehicle, for the purpose of AUC reliability test. Results: In a weighted model with 11 items, the AUC was 0.8155 in the primary study population, and 0.8026 in the secondary study population(p=0.3780). It was superior in the aspects of discriminability, reliability and convenience. A new questionnaire of musculoskeletal disorder could be constructed by this model. Conclusion: A more valid questionnaire with a small number of items and the quantitative weight scores useful for the relative comparisons are the main results of this study. While the absolute reference value applicable to the wide range of populations was not estimated, the basic intent of this study, developing a surveillance fool through quantitative validation of the measures, would serve for the systematic disease prevention activities.

The effects of liquid culture of Coriolus (C) versicolor on weight gain, food intakes, food efficiency ratios, serum and hepatic lipid concentrations were investigated in male rats fed the high cholesterol diets. Eight weeks old Sprague-Dawley rats were given three different types of diet for six weeks, respectively: a control diet ($ 20\% fat +0.5 \% $ cholesterol), two kinds of C versicolor diet (control diet + $ 30\% or 40\%$C. versicozor in water) according to the levels of C. versicolor supplementation. The body weight gains of the rats fed $ 30\% or 40\% $ C. versicolor diets were lower than those in the rats fed the control diet. The food intake, food efficiency ratios, and liver, kidney, epididymal fat pad weights of the rats fed $ 30\% or 40\%$ C. versicoEer diets were similar to those of the rats fed the control diet. The concentrations of hepatic cholesterol and triglyceride in the rats fed $ 30\% or 40\% $ C. versicolor diets were significantly lower than those in the rats fed the control diet. The concentrations in serum total cholesterol, LDL-cholesterol, and atherogenic index ratios were significantly lower in the rats fed $ 30\% or 40\%$ C. versicolor diets compared to those fed the control diet. The HDL-cholesterol/total-cholesterol ratios was significantly higher in the rats fed $ 30\% or 40\% $ C. versicolor diets compared to those fed the control diet. The fecal excretion of total lipid and triglyceride in the rats fed $ 40\% $ C. versicolor diet was significantly higher than that of the rats fed the control diet. There were no significant difference found in the serum trigly-ceride, phospholipid and HDL-cholesterol concentrations among the experimental groups. These results showed that the C. versicolor feeding decreased the hepatic cholesterol, triglyceride, and the serum total cholesterol, LDL-cholesterol and atherogenic index, and increased the serum HDL-cholesterol/ total-cholesterol ratio of the rats.

The standardization of marketing has been one of the most focused research topics in international marketing. The term "global marketing" was often used to mean an internationally standardized marketing strategy based on similarities between foreign markets. Marketing standardization was discussed only within the context of traditional physical marketplaces. Since then, the digital "marketspace" of the Internet had emerged in the 90's, and it became one of the most important drivers of the globalization process opening new opportunities for the standardization of global marketing activities. On the other hand, the opinion that a greater adoption of the Internet by customers may lead to a higher degree of customization and differentiation of products rather than standardization is also quite popular. Considering this disagreement, it is notable that comprehensive studies which focus upon the marketing standardization especially in the context of global e-commerce are missing to a high degree. On this background, the two basic research questions being addressed in this study are: (1) To what extent do companies standardize their marketing in international e-commerce? (2) Is there an impact of marketing standardization on the performance (or success) of these companies? Following research hypotheses were generated based upon literature review: H 1: Internationally engaged e-commerce firms show a growing readiness for marketing standardization. H 2: Marketing standardization exerts positive effects on the success of companies in international e-commerce. H 3: In international e-commerce, marketing mix standardization exerts a stronger positive effect on the economic as well as the non-economic success of companies than marketing process standardization. H 4: The higher the non-economic success in international e-commerce firms, the higher the economic success. The data for this research were obtained from a questionnaire survey conducted from February to April 2005. The international e-commerce companies of various industries in Germany and all subsidiaries or headquarters of foreign e-commerce companies based in Germany were included in the survey. 118 out of 801 companies responded to the questionnaire. For structural equation modelling (SEM), the Partial-Least. Squares (PLS) approach in the version PLS-Graph 3.0 was applied (Chin 1998a; 2001). All of four research hypotheses were supported by result of data analysis. The results show that companies engaged in international e-commerce standardize in particular brand name, web page design, product positioning, and the product program to a high degree. The companies intend to intensify their efforts for marketing mix standardization in the future. In addition they want to standardize their marketing processes also to a higher degree, especially within the range of information systems, corporate language and online marketing control procedures. In this study, marketing standardization exerts a positive overall impact on company performance in international e-commerce. Standardization of marketing mix exerts a stronger positive impact on the non-economic success than standardization of marketing processes, which in turn contributes slightly stronger to the economic success. Furthermore, our findings give clear support to the assumption that the non-economic success is highly relevant to the economic success of the firm in international e-commerce. The empirical findings indicate that marketing standardization is relevant to the companies' success in international e-commerce. But marketing mix and marketing process standardization contribute to the firms' economic and non-economic success in different ways. The findings indicate that companies do standardize numerous elements of their marketing mix on the Internet. This practice is in part contrary to the popular concept of a "differentiated standardization" which argues that some elements of the marketing mix should be adapted locally and others should be standardized internationally. Furthermore, the findings suggest that the overall standardization of marketing -rather than the standardization of one particular marketing mix element - is what brings about a positive overall impact on success.

The present study was conducted to compare the carcass yields and meat characteristics of three types of commercial male chicks White mini broilers, Ross broilers and Hy-Line brown chicks under the identical feeding condition. One-hundred 1-d chicks of each type were randomly placed into four pens per group (25 chicks per pen) and fed corn-soybean meal based commercial diets for 35d, 18d or 49d, respectively. At the end of the feeding trial, the birds were sacrificed and subjected to carcass measurements. The dressing percentages of White mini broilers and Ross broilers were significantly higher (P<0.05) than that of Hy-Line brown cockerels. The rate of breast meat of Hy-Line brown cockerels was significantly lower (P<0.05) than those of White mini broilers and Ross broilers. However, Hy-Line brown cockerels showed higher (P<0.05) leg meats than the others. There were no significant differences in serum total cholesterol and the activities of glutamic-oxaloacetic transaminase and glutamic-pyruvic transaminase among the groups. The breast meats of White mini broilers presented highest lightness value. The yellowness of breast and redness of leg meats of White mini broilers and Ross broilers were significantly higher (P<0.05) than those of Hy-Line brown cockerels. There were no significant differences in the SOD-like activity and change of pH in edible meats among the groups. The meat color in White mini broilers was significantly higher than that of Hy-Line brown cockerels. No significant differences were observed in term of flavor, tenderness and overall acceptability. In conclusion, the physico-chemical properties and sensory characteristics of edible meats were not greatly affected by genotype if they were similar body weights and kept under the identical feeding condition. But the Hy-Line brown cockerels were less desirable as a meat-type strain due to lower carcass yields and inferior growth and feed conversion ratio.
