  • In this study, we individualize the clauses to sort out the troubled ones, draw up a interrelation model in order to visually organize the relations, and finally, suggest the desirable application idea. The interrelation model suggested in this study has been made based on the matrix method. On this matrix, we arranged the environmental factors on horizontal and vertical axis, and when we describe the relation of each factors, we set the horizontal axis as the base and divided the content into three grades : Fine, Medium, and Poor. In addition to that, we expressed those three grades into numerical value like 3 points for Level Fine, 2 points for Level Medium, and 1 point for Level Poor and then, we converted this numerical values into index numbers. We could classify the index numbers such as AS, PS, Q-index, P-index. AS is an index numerically shows the degree of giving environmental effect, PS is an index numerically shows the degree of receiving environmental effect, Q-index is an index shows the aggravate degree, and P-index shows the relation degree. The Q/P-index with large numbers has considerable effect on the environmental system, while the small numbered Q/P-index barely effect on the environmental system. Moreover, we classified the environmental factors into 5 levels(I~V) according to the relations between the Q-index and P-index. Level I is less affected by the environment and has more giving effect, while Level V is more sensitively affected by the environment and has more receiving effect, which we considered important. Therefore, we could come up with the result that if we consider the each level of factors when we evaluate the EIA, the result would be far more accurate and reliable since it contains mutual relation aspect of EIA. The suggested interrelation model in this thesis is presentable as one of those scoping system. We highly believe the need of scoping system in EIA and suggest the interrelation model as the alternative idea for scoping system.

  • The purpose of pilot clinical trial is to evaluate the efficacy and safety of acupuncture therapy on TEWL(Transepidermal Water Loss) and skin hydration. A total of 36 human who visited Dongshin University Oriental Medical Center from October 2nd, 2015 to July 31st, 2016 were included in the pilot clinical trial. Acupuncture therapy was performed at Gokji(LI11) and Daechu(GV14). We observed change of TEWL(Transepidermal Water Loss), skin hydration before and after acupuncture therapy. In the primary endpoint, index of TEWL showed a statistically significant decline($8.01{\pm}2.55{\rightarrow}6.58{\pm}1.97g/h/m2$, $7.40{\pm}2.65{\rightarrow}4.99{\pm}1.89g/h/m2$). Index of skin hydration showed statistical significance($52.83{\pm}6.53{\rightarrow}56.82{\pm}7.24$, $63.50{\pm}8.57{\rightarrow}64.96{\pm}8.48$). To evaluate the safety, vital sign check were conducted and showed no statistically significant result. And there were no severe adverse events during this study. According to the above pilot clinical trial, it is suggested acupuncture therapy were effective for skin moisturizing.

  • Objective: The purpose of this study was to examine the effects lumbar stabilization exercise with kinesio taping on pain, muscle strength, and oswestry disability index (ODI) in patients with chronic low back pain. Design: Two groups pre-post randomized controlled design Methods: Thirty-two subjects were randomly divided in two groups; 1) lumbar stabilization exercise with kinesio taping group (Experimental group, n=16), 2) lumbar stabilization exercise with sham kinesio taping group (Control group, n=16). The intervention was conducted in each group for thirty minutes a day, 5 times a week, for 4 weeks. Both group did 30 minutes of lumbar stabilization application. Evaluations were performed before the commencement of training and again 4 weeks after training was initiated. Visual analog scale (VAS) was used to evaluate pain level of patients with chronic low back pain. Distal muscle test was used to evaluate muscle strength of trunk extension. In addition, ODI was used to evaluate activity daily life of low back pain. Results: After training, the VAS, muscle strength of trunk extension and ODI were significantly more improvement in Experimental group than in the control group (p<0.05). Conclusions: We confirmed that the effects of lumbar stabilization exercise with kinesio taping group on pain, muscle strength, and ODI in patients with chronic low back pain.

  • This test was performed to evaluate the ocular and skin irritation of EPO (Erythropoietin). The results as follows: 1. Ocular irritation test There were no observed clinical signs, body weght changes by EPO during experimental period. The acute ocular irritation index(A.O.I.), mean ocular irritation index(M.O.I.) and Day-7 individual ocular irritation index(I.O.I.) of EPO at dose of 1000U and 10, 000U were 0, respectively. Therefore we evaluated that EPO was non-toxic to eyes. 2. Skin irritation test There were no observed clinical signs, body weght changes and gross pathologic findings by EPO during experimental period. There were no observed erythema, eschar formation and edema formation on intact and abraded skin treated by EPO. The primary irritation index(P.I.I.) of EPO at dose of 1000U and 10, 000U were 0, respectively and were evaluated none irritating product about skin irritation.

  • Objective : This study was performed to evaluate the effect acupuncture on cerebral blood flow by Transcranial Doppler Ultrasonography(TCD). Methods : Monitoring of TCD was examined in stroke patients before and after acupuncture on seven points of CVA. Mean Velocity, pulsatility index, systolic velocity, diastolic velocity values are analyzed from TCD at middle cerebral artery. Results : The results showed a insignificant(p>0.05: Paired T-test) decrease in mean velocity, pulsatility index, systolic velocity, diastolic velocity, which was measured at normal middle cerebral artery. The results showed a significant($p{\leq}0.05$: Paired T-test) decrease in mean velocity, pulsatility index, systolic velocity, which was measured at injuried middle cerebral artery, except diastolic velocity. Conclusion : These results suggest that acupuncture could have a specific effect on injuried cerebral artery.

  • The online retail market continues to grow, especially in China, as e-commerce has developed rapidly in recent years in many countries. Meanwhile, the development and use of new network information technology provides consumers with various contact and experience environments for online shopping. Based on the theory of media weakness, the study began to focus consumer experience on the nature of commercial transactions. The study proposed and designed an initial measure of the consumer information evaluation index, which combines previous findings with implications. Finally, the five-dimensional B2C system was established to evaluate consumers' information experience providing information display, information interaction, information support and information personalization. We researched on evaluation index system for information experience of B2C e-commerce consumers based on samples of Chinese consumers.

  • The present study covers an integrated simulation method to evaluate optical performance of an aspheric plastic lens by connecting an injection molding analysis with a ray tracing simulation. Traditional ray tracing methods have based on the assumption that the optical properties of a lens are homogeneous throughout the entire volume. This assumption is to a certain extent unrealistic for injection-molded plastic lenses because material properties vary at every point due to the injection molding effects. To take into account the effects of the inhomogeneous optical properties of the molded lens, a numerical scheme is developed to calculate the distribution of refractive index induced from the injection molding process. This index distribution is then reflected onto CODE $V^{(R)}$ simulation and used to calculate ray paths in inhomogeneous media. The proposed tracing scheme is implemented on the tracing of an aspheric lens for a mobile phone camera module.

  • Maloperation of protective relays is one of the major causes for cascading tripping in WANS. Another line trip followed by a previous line trip may occur due to overloading of the line, because of the load redistribution or unwanted trip of a backup relay due to change in the flow of fault current. Evaluation of each line is required by considering both of these effects. A new index named Line Security Index (LSI) is proposed in this paper which combines both Vulnerability Index (VI) and Protectability Index (PI) to completely evaluate the security of individual lines and their importance in the power grid. Computer simulations have been performed on the Korean power grid data to establish the feasibility of the proposed idea.
