Objectives : Chronic pain affects and is affected by physical and psychosocial factors. It also has a complicated and indefinite mechanism. This research is for clarifying relations with chronic pain, stress, and autonomic nerve system by comparing HRV and Stress Reaction Index(SRI) of chronic pain patients with those of acute pain patients. Methods : The subjects were 32 patients who visited Kangnam Kyunghee Hospital for nuchal pain or low back pain treatment from March 2008 to September 2008. Among them, 16 patients who suffered over 6 months are classified chronic pain group and 16 patients who suffered under 6 months as acute pain group. All subjects had their HRV(SA-2000E: Medicore Co..Ltd. Korea) and SRI measured at first visit. We studied the difference of HRV between two groups.(Statistics by Student t-test, p<0.05) Results : R-MSSD, TP, VLF, LF, HF and LF/HF ratio of the chronic pain group were significantly lower than those of the acute pain group. Compared with those of the acute pain group, total SRI of the chronic pain group were low but it's not significant except frustration. Conclusion : The results of HRV of the chronic pain group patients show that chronic pain is related to psychosocial factor and autonomic disturbance.

The seasonal and spatial diversity of picocyanobacteria (Pcy) in lakes of the Great Mazurian Lakes (GLM) system was examined by DGGE analysis of molecular markers derived from the 16S-23S internal transcribed spacer (ITS) of the ribosomal operon and the phycocyanin operon (cpcBA-IGS). The study of nine lakes, ranging from mesotrophy to hypereutrophy, demonstrated seasonal variance of Pcy. The richness and Shannon diversity index calculated on the basis of both markers were higher in spring and lower in early and late summer. No statistically significant relationships were found between the markers and trophic status of the studied lakes or Pcy abundance. There were, however, statistically significant relationships between the diversity indices and sampling time. The analysis pointed to a different distribution of the two markers. The ITS marker exhibited more unique sequences in time and space, whereas a greater role for common and ubiquitous sequences was indicated by the cpcBA-IGS data. Examination of the Pcy community structure demonstrated that communities were grouped in highly similar clusters according to sampling season/time rather than to the trophic status of the lake. Our results suggest that time is more important than trophic status in shaping the diversity and structure of Pcy communities. The seasonal changes in picocyanobacteria and differences in diversity and community structures are discussed in the context of well-established ecological hypotheses: the PEG model, intermediate disturbance hypothesis (IDH), and horizontal gene transfer (HGT).

This study investigated the body image, body stress, eating attitude, and dietary quality in middle school girls. Questionnaires were administered to one hundred fifty seven middle school girls in Seoul area. The subjects were categorized into the five groups according to their body mass index (BMI); 1) severely under-weight (BMI < 16.5 $kg/m^2$), 2) under-weight (16.5 $\leq$ BMI < 18.5 $kg/m^2$), 3) normal weight (18.5 $\leq$ BM I < 23.0 $kg/m^2$), 4) overweight (23.0 $\leq$ BMI < 25.0 $kg/m^2$), and 5) obese (BMI $\geq$ 25 $kg/m^2$). 7.0%, 14.6%, 58.9%, 10.2%, and 10.2% of the subjects were classified as severely under-weight, under-weight, normal weight, overweight and obese groups, respectively. Regardless of the BMI, the subjects had disturbed body image, body stress, and poor eating attitude. The actual BMIs of the normal weight, overweight and obese subjects were significantly different from their desired BMI and perceived BMI, representing these subjects dissatisfied their body shape. Almost all subjects tried to lose their body weight even in the severely under-weight and under-weight groups. There were significant correlations of BMI with body image disturbance (p < 0.05), body stress (p < 0.01) and eating attitude (p < 0.05). These results indicated that middle school girls who have higher BMI seemed to have more body image distortion, body stress and risk of eating disorder. However, any significant difference in dietary quality among the five groups was not observed even though their dietary patterns were not balanced. As a conclusion, it is required that middle school girls should correct their distorted body image and body stress. Also, efforts to improve eating attitude, dietary pattern and nutritional status in the middle school girls are needed.

The purpose of this study is to discovered assessment items for improving athletic efficiency and management of golf courses. Through this, the study intended to provide basic data for creating competitive golf courses and management. Important assessment items were selected by inducing preliminary assessment items and conducting a preliminary survey and a main survey for specialists through a theoretical study. For the survey results studied, reliability and average value for importance were calculated using SPSS/PC Window Release 12.0. As assessment of importance by assessment area, in athletic efficiency assessment, course management level was the highest, followed by fairness of games and operation of games. In management assessment, importance of service level, information management, facility management, management of game assistants, etc. were high. As assessment of importance by assessment item, it was found that 'variety of golf shot' and 'the length of a course' were important in course layout. Also 'start interval among teams' and 'disturbance of play' were assessed as important items in game operation, while 'fair reservation' and 'rounding rotation time' were important in fairness of games. In addition, in information management, 'kind service of golf course staffs' and 'prompt reservation and notification' were found to be important assessment items. In facility management, all assessment indexes were over 4.0, which means all of them are important for quality of golf course and competitiveness. In membership service, 'appropriate price of goods for sale' and 'service for members' were relatively important assessment items. Further, in management of game assistants, 'qualifications and skillfulness of game assistants' was assessed as a very important index. Although the current study only selected important items to assess excellent golf courses, it is necessary to apply the study results to the actual sites and verify them for golf course both at domestic and abroad.

The purpose of this study is to develop a pipe type soil sampler that can easily collect soil cross section servey and soil samples to conduct ecological environment surveys while minimizing ecological disturbance in the area subject to soil survey. Furthermore, this study develop the exponential type estimation specific weight formula (ESWF) that uses pipe type soil sampler to easily carry out soil cross section survey and soil sample while estimating the specific weight of the area using water content and soil sample length variation ratio (SLVRs) and to obtain apparent specific gravity, hardness, and max. porosity which are used as growth of corps and ecological environment index. The calibration results of ESWF showed a high degree of significance, with NSE for actual specific weight (γ₀) and calibration estimation specific weight (γ_ec) 0.95, R² for 0.954, and RMSE for 0.051. The verification results of ESWF showed a high significance, with NSE for actual specific weight (γ₀) and verification estimation specific weight (γ_ev) 0.881, R² for 0.978, and RMSE for 0.055.

The patency of small size vascular grafts is poor, and the blood flow characteristics in the artery graft anastomosis are suspected as one of the important factors influencing intimal hyperplasia. Disturbed flow patterns caused by sixte and compliance mismatch generate unfavorable flow environment which promotes intimal thickening. Tapered vascular yuts are suggested in order to reduce sudden expansion near the anastomosis. The photochromic flow visualization method is used to measure the flout fields in the end-to-end anastomosis model under the carotid and femoral artery flow wave form. The results show that flow disturbance near the anastomosis is diminished in the tapered grafts comparing to the tubular graft. As the divergent ang1e decreases, we can reduce the low and oscillatory wall shear stress zone which is prone to intimal hyperplasia. The flow wave form effects the wall shear rate dis- tribution significantly. The steep deceleration and back flow in the femoral flow wAve form cause low mean wall shear rate and high oscillatory shear index.
