  • The purpose of this study was to investigate the effect of Forest-walking exercise on gait pattern in the elderly. The subjects (n=37) were assigned to 2 groups: Forest-walking exercise (FWE) group (n=19, $66.34{\pm}4.31$ years old) and In-door treadmill-walking exercise (ITWE) group (n=18, $67.18{\pm}2.78$ years old). The subjects participated in FWE program or ITWE program (3 times/week, 80 min/day) for 12 weeks. The subjects were tested on functional fitness (strength, endurance, agility/balance, BMI) and gait pattern (cadence, velocity, and stability) at the beginning and the end of the 12-weeks program. For data analysis, mean and standard deviation scores were calculated, and independent t-test and repeated two-way ANOVA were used. The results of this study were as follow: First, FWE group was significantly more improved than ITWE group on functional fitness(lower-body muscular strength, lower-body flexibility, mobility, cardiorespiratory endurance) after 12-weeks exercise program. But both groups showed equally improvements on functional fitness (upper-body muscular strength, upper-body flexibility, BMI). Second, FWE group was significantly more improved than ITWE group on cadence, gait velocity, and gait stability after 12-weeks exercise program. Therefore, this study may suggest that Forest-walking exercise based on sensory-motor functional integration improves efficiently functional fitness and gait pattern in the elderly, and further becomes an effective exercise method that makes more dynamic life, and prevents from falling.

  • Perilla is an excellent oil crop for linolenic acid production but still needs more research to improve grain yield and chemical properties. We tried to estimate the possibility for improving grain yield and its quality by applying nitrogen top dressing(4kg per 10a) at 5 days after flowering stage of perilla, using a cultivar Yujin. This study investigated the growth characteristics and seed quality. Nitrogen top dressing on the flowering stage has little affected on such traits as length, node number and diameter of main stem, and branch, cluster and capsules numbers per plant. But compared with standard cultivation as a control, top dressing showed more leaf chlorophyll content by 85%, higher 1000-grain-weight by 31%, and one day extension of maturing period; consequently, grain outyielded by 60% with 123kg per 10a. Seed chemical components also showed 33.3% protein and 48% oil contents that were 11.5% and 6.2% higher than those of control, respectively. Also by top dressing, saturated fatty acid (palmitic and stearic acid) decreased and linoleic acid among unsaturated fatty acids increased. It is concluded that nitrogen topdressing at late flowering stage promotes grain yield and quality of perilla.

  • Objectives : Stroke is the most common disabling neurological disease of adult life. The treatment and rehabilitation of stroke patients is an important and challenging area in the field of medicine. In Korea, a lot of stroke patients are treated using oriental medicine and there have been reports on their functional recovery. The aim of this study was to prove the therapeutic effect of oriental medicine on ischemic stroke. We also tried to identify characteristics of patients whose functional recovery was prominent and studied whether or not the use of fluids, anticoagulants, antiplatelets and neuroprotective agents increased the functional recovery of patients. Methods : We studied 794 patients within 2 weeks after first attack of ischemic stroke who were admitted to Kyung-Hee Oriental Medical Center from 1999 to 2000. Their maximum admission period was 60 days. Results : Motor power grade, NIHSS and MBI scores of patients improved during hospitalization significantly. Factors affecting functional recovery were admission period, motor power grade, NIHSS and MBI at admission. Age, waist-hip ratio and HDL cholesterol also affected functional recovery of patients. Whether or not fluids, anticoagulants, antiplatelets and neuroprotective agents were administered had nothing to do with functional recovery. Conclusion : Oriental medicine is effective for treatment and rehabilitation of ischemic stroke patients. When we manage stroke, we have to consider some important factors.

  • In this study, various conflicts in the maritime police organization were diagnosed and police subculture, which is different from dominant mainstream maritime police culture, was concluded to cause conflicts. In addition, maritime police conflicts and conflicts due to the balance, confrontation, and contradiction between bureaucratic and democratic values in the maritime police organization itself are discussed. The results of analysis on the effects of Maritime police subculture on organizational conflict are as follows: First, the influence of cynicism on functional conflict was explored. The higher the level of lies of the persons under investigation, the more functional conflict appeared. Also, if a person showed a low level of credibility among the police, this also led to functional conflict. In addition, if an individual showed low levels of cooperation and credibility with the police, this resulted in hierarchical conflict. Second, the influence of machismo on functional conflict was also explored. It was found that female officers experienced conflicts because of poorer job performance compared to male counterparts. In hierarchical issues, female officers experienced conflict over the reduced scope of tasks assigned to them and lower job performance ability. Third, the effect of non-acceptance of change in functional conflict was not statistically significant. An aggressive attitude toward crime control and rejecting jobs unrelated to crime influenced functional conflict, and an aggressive attitude and performing jobs unrelated to crime lead to functional conflict.

  • Kiwifruit (Actinidia chinensis, Hayward) was stored at $25^{\circ}C$ for 0~30 days and investigated to find out the optimum storage time to obtain the best physical and functional properties for consumers' preference. Kiwifruits was stored at different time period (0, 5, 10, 15, 20, and 30 days) for investigating their physiochemical quality, nutritional components, and functional characteristics. Kiwifruits stored for 20~30 days showed the best physiochemical quality such as higher total acidity and proper firmness. They were also more enriched with dietary fibers, free sugar, and organic acid, although no significant changes were observed in crude protein, crude fat, and moisture content. For functional properties, kiwifruits stored for 20 days showed significantly higher contents of total phenolics, flavonoids, and actinidin. In addition, it showed stronger antioxidant activity, whitening effect, and proteolytic activity when compared with other samples. SDS-PAGE analysis showed the presence of actinidin enzyme in kiwifruits. These results indicated that the kiwifruits stored for 15~20 days possessed excellent quality and high concentrations of nutritional and functional compounds, which could be best for both fresh consumption and product processing.

  • This study was conducted to evaluate the weed suppressing effects of different cropping system including hairy vetch (Vicia villosa) and rye (Secale cereale) cover crops, polyethylene plastic film, and transplanting film mulching in direct sowing and transplanted sorghum field in 2011. Crop growth and development and weed occurrences in the fields were examined to know the efficiency of proposed cropping system. In polyethylene film mulching treatment, heading date of sorghum was earlier by 3 days than control, on the other hands, rye cover crop mulching delayed heading date by 11 days. Besides the effect of cover crop on the heading of sorghum, the residues changed growth characteristics. Plant height of sorghum was increased by 27.3% at hairy vetch treatment although it was reduced by 47.5% in the rye cover crop treatment. Hairy vetch treatment showed beneficial effects on sorghum growth reduced the occurrences of grasses and broadleaf weeds to 84% and 96%, respectively, as compared to control in sorghum fields. While rye cover crop treatment showed poor sorghum growth reduced less strongly grasses and broadleaf weeds by 35% and 71%, respectively. At harvest, yield of sorghum was greater in order of hairy vetch cover crop > polyethylene film mulching > rye cover crop ${\fallingdotseq}$ control in both transplanted and direct sown fields.

  • Purpose - This empirical analysis determines the structured causal relations between perceived value, customer satisfaction, and repurchase intention among users of traditional markets. The results of this analysis would help merchants and market operators indevisingan appropriate strategy to successfully manage traditional markets. Research design, data, methodology - The perceived value model of traditional markets includes functional value (price), functional value (quality), emotional value, and social value. In this study, the perceived value of traditional markets is considered as an independent variable, while customer satisfaction and repurchase intention are shown as the dependent variables, where customer satisfaction is also considered as the mediating variable. The study aims to ascertain the extent of influence of the perceived value of traditional markets on customer satisfaction and repurchase intention. We use regression analysis to verify the effects. The measurement items were already deemed as reliable and valid in the previous study, but for this purpose, we made some modifications. We distributed questionnaires to 300 consumers on a national scale, and finally used 241 consumer responses among these as a sample. We analyzed the data using the SPSS 21.0 statistical program. Results - We obtained the following results. First, the order of perceived value dimensions of traditional markets that positively impact customer satisfaction is functional value (price), social value, emotional value, and functional value (quality). Second, the perceived value sometimes directly affects repurchase intention; its effect is typically strong with customer satisfaction as a parameter. The order of perceived value dimensions that positively impact repurchase intention is social value, functional value (price), emotional value, and functional value (quality). Third, the perceived value significantly influences repurchase intention, with customer satisfaction as the mediating variable. Conclusions - We should recognize the importance of perceived value in retail distribution markets, such as traditional markets. Moreover, we need to develop strategies to improve the perceived value. The practical implications of the study are as follows. First, with regards to functional value (quality; price) dimensions, we should have an appropriate assortment of high quality products that are reasonably priced. In addition, customers are satisfied with the friendly service, discounts, and other benefits provided by the merchants. Second, in terms of emotional value dimension, we need to develop differentiated events that provide fun and emotional experience to the customers. Third, in the context of social values dimension, we should strive to positively influence society to enhance social image through activities such as social services and contribution to community development. On the basis of these results, we present the implications, limitations, and future directions for the research. One of the policy implications of the study is that merchants of traditional markets must actively select customers and develop customer value. However, this study is limited in the fact that the population used for data collection is not fully representative, as the survey only covered some specific areas. Moreover, future studies could also benefit with additional research using moderating variables.

  • BACKGROUND The purpose of this study was to find out predictors influencing on the clinical course of stroke during the first 4 weeks after the onset through statistical research, especially whether the blood glucose level after stroke and the stroke with Diabetes Mellitus correlate with functional impairments and neurological outcome or not. METHOD During 7 months period(from 1-1-1997 to 7-31-1997), 32 selected patients prognosed as acute cerebral thrombosis were studied by using Modified Barthel Index, PULSES profile in an attempt to correlate Diabetes Mellitus and hyperglycemia(more than $120mg/d{\ell}$, $150mg/d{\ell}$) with functional impairment and neurological outcome and to evaluate the influence of sex, the side of hemiparesis and age at admission, 1 week and 4 weeks after admision(admitted within 2 days after the onset). RESULT 1. The sex, side of hemiparesis and age had no significant effect upon functional impairment during first 4 weeks after the onset, but recurrent-stroke resulted in significantly higher degree of functional impairment than first-stroke during first 4 weeks after the onset. 2. The patients with Diabetes Mellitusin in acute cerebral thrombosis resulted in significantly higher degree of functional impairment than the patients without Diabetes Mellitus in acute cerebral thrombosis during first 4 weeks after the onset. 3. The patients with hyperglycemia in acute cerebral thrombosis resulted in significantly more severe neurological outcome than the patients without hyperglycemia in acute cerebral thrombosis within 2 days after the onset. CONCLUSION The study suggested that recurrent-stroke and Diabetes Mellitus were the poorer prognosis factors of functional impairment in acute cerebral thrombosis patients during first 4 weeks after the onset. and the poorer prognosis factor of neurological outcome in acute cerebral thrombosis patients was hyperglycemia within 2 days after the onset.

  • As the aluminum (Al) metallization process was replaced with copper (Cu), the damascene process was introduced, which required the planarization step to eliminate over-deposited Cu with Chemical Mechanical Polishing (CMP) process. In this study, the verification of the corrosion inhibitors, one of the Cu CMP slurry components, was conducted to find out the tendency regarding the carboxyl and amino functional group in neutral environment. Through the results of etch rate, removal rate, and chemical ability of corrosion inhibitors based on 1H-1,2,4-triazole as the base-corrosion inhibitor, while the amine functional group presents high Cu etching ability, carboxyl functional group shows lower Cu etching ability than base-corrosion inhibitor which means that it increases passivation effect by making strong passivation layer. It implies that the corrosion inhibitor with amine functional group was proper to apply for 1st Cu CMP slurry owing to the high etch rate and with carboxyl functional group was favorable for the 2nd Cu CMP slurry due to the high Cu removal rate/dissolution rate ratio.
