  • To assessment the disturbances of the Namgang caused by dam construction, upstream area was selected for the reference reach and downstream area was selected for the comparison reach. And these reaches were surveyed and analyzed according to the assessment criteria of the river disturbances.The artificial factors of river disturbances were classified as river improvement works, dam construction and aggregate dredging. The indexes were physical factors as like epifaunal (bottom), embeddedness, velocity/depth regime, sediment deposition, channel flow status, channel alteration, frequency of riffles, bank stability, vegetative protection, riparian zone etc.The assessment results showed 46% of the assessment criteria which was serious status in dam downstream area and 89.5% of it which was excellent status in dam upstream.Finally, the results showed that physical river environment in downstream area was disturbed by the discharge control and the interception of sediment discharge by dam, consequently this disturbance give rise to impact of ecosystem in river.

  • The purpose of this study was to investigate the effect of a single treatment o voltage pulsed current (HVPC) on edema reduction. Hind limbs of 23 anesthetized were injured by dropping a 400 g weight onto the plantar aspects of the feet. On limb of each frog was randomly selected to receive 30 minutes of continuous, 12 cathodal HVPC at voltages 10 % less than motor threshold levels. Limb volumes measured by water displacement before trauma and at predetermined intervals hours posttrauma. Sources of significant differences were determined by t-test HVPC significantly (p<0.05) reduced edema formation. We hypothesize that HVP also be effective in controlling edema formation after impact injuries in humans.

  • It is naturally to be expected that occupational stress on seafarers has specific characters compared to workers engaged in other industries. Because the physical rigors of working and living at sea has been endured as a part of job. The purpose of this paper is to figure out physical changes on seafarers resulted from ordinary shipboard life on the ocean-going cargo vessel. To do this, we performed biochemical inspections testing blood and urine for 28 crews, and measured heart rate of officers engaging in some bridge duties. The tests showed that creatinine, uric acid, total cholesterol, HDL-C, LDL-C of some crews fell down to level which could make a bad impact on human body. And the heart rate of deck officers had vibrated with rather wide amplitude whenever they have got some work-related psychological pressure.

  • The purpose of the current study is to investigate the underlying reasons of fashion brand repurchase intention formation based on means-end chain theory and to identify whether the price level moderates the relationships between attribute evaluation and re-purchase intention. Questionnaire data from 291 consumers who had purchase experience of casual wear during the last 6 month period through off-line retail shops were analyzed. The results showed that hedonic shopping value had a positive impact on aesthetic attribute and utilitarian shopping value also had a positive impact on physical attribute of fashion product. While aesthetic attribute had a positive influence on brand repurchase intention, physical attribute had no effect on brand repurchase intention. In addition, there was no moderating effect of price level between the links from shopping value to fashion product attribute evaluation. When casual wear companies have to devise price related strategies, they need to pay attention to diverse promotion factors except for product attributes to realize price-based differentiation.

Method : All subjects were treated with air-pressure cervical traction while 15 minutes a day, 3 times per week, for 4 weeks. The effects of air-pressure cervical traction were evaluated by HIT-6(headache impact test), VAS, and flexion, extension, left right flexion, left right rotation of cervical ROM. The measured data were analyzed by using repeated ANOVA. Especially in order to investigate the effect of air-pressure cervical traction. The comparison with among three measurement time. Results : The results of this study were as follows; 1) Prior and two weeks measurement did not show significant differences. The head forward posture than before the experiment, each experimental group was significantly increased(p<.05). 2) Prior and two weeks measurement did not show significant differences. The experimental group than ever cervical ROM of the movable range increased significantly(p<.05). 3) The experimental group was significantly lower than before the VAS(p<.05). 4) HIT score of the experimental group was significantly lower than before(p<.05). Conclusion : These findings suggest that air-pressure cervical traction had effect on the tension headache in the adults.

  • The purpose of this study was (a) to develop carbon nanotube-based shock absorbers for reducing potentially harmful impact forces and excessive foot pronation, and (b) to briefly determine how the effects of carbon nanotube-based shock absorbers on biomechanical variance during drop landing. A university student(age: 24.0 yrs, height: 176.2 cm, weight: 679.5 N) who has no musculoskeletal disorder was recruited as the subject. Hardness, specific gravity, tensile strength, elongation, 100% modulus, tear strength, split tear strength, compression set, resilience, vertical GRF, and loading rate were determined for each material. For each dependent variable, a descriptive statistics was used for different conditions. The property test results showed that tensile strength, tear strength, split tear strength, compression set, and resilience in carbon nanotube-based shock absorbers were greater than general Ethylene Vinyl Acetate(EVA). These indicated that resistance against variable strength in developed carbon nanotube-based shock absorbers were greater than general EVA. In vertical GRF of CNTC was less than those of EVA during drop landing and loading rate of CNTC was greater than EVA. It seems that the use of CNT can be a effective way of reducing and controlling shock from impact.

  • The purpose of this study was (1) to examine the impact of chronic diseases on adolescent's peer relationships, and (2) to investigate the mediating effect of self-perceived health status and resilience on the relationship between their physical health states and peer relationships. The authors used the first-wave panel data from 'the Korean Children-Youth Panel Survey'. The sample included 2,351 first-grade of middle school students(boys 50.1%, girls 49.9%). Among the subjects examined 48.11% had chronic diseases. Using maximum likelihood estimation with Amos18(Arbuckle, 2009), SEM software, structural equation modeling was tested. The major findings were as follows : 1. Adolescents' chronic diseases had a negative impact on peer relationships. 2. Self-perceived health status and resilience had a mediating effect. This suggests that self-perceived health status and resilience could be protective factors when it comes to perceive peer relationships more positively for adolescents with chronic diseases. 3. Resilience was directly affected by self-perceived health status. This indicates that positive self-perception about their health status encourages adolescents with chronic diseases to be more resilient and to more positively affect their perception of their relationships with peers.
