This study aims to help understanding on design of basic pattern of shirt collars and to suggest schemes to raise completeness of shape by reviewing problems shown in finished products after sewing. From March 2009 to August 2009, 12 patterns for education and firms were collected centering on basic shirt collar form respectively. There are four problems generally raised from a completed shirt collar. In case of overlapping shirt collar on front neck point, the sewing point of shirt collar should be drawn at front neck point of collar band at a distance of about 0.2~0.3cm, and the center front of band and one of bodice should be arranged in a straight line. In case of the problem about right and left length difference of shirt collar, it is raised by closing so the problem was solved by prolonging about 0.2 cm of the center front of left collar. It was evaluated that adjusting notch point when sewing would be more rational solution than solving something on patterns for distance difference problem of shirt collar between right and left part at center front. And a problem about getting loose of front garment between collar band below and the first button was also raised. It was designed 0.2cm cut of collar band. Around basic shirt collar form, above mentioned solutions are applied to the patterns for education and manufacture experimental clothing. So as a result of sensory evaluation, generally good ratings on all items were received.

In this paper we introduce and consider a new class of variational inequalities with four operators. This class is called the extended general mixed quasi variational inequality. We show that the extended general mixed quasi variational inequality is equivalent to the fixed point problem. We use this alternative equivalent formulation to discuss the existence of a solution of extended general mixed quasi variational inequality and also develop several iterative methods for solving extended general mixed quasi variational inequality and its variant forms. We consider the convergence analysis of the proposed iterative methods under appropriate conditions. We also introduce a new class of resolvent equation, which is called the extended general implicit resolvent equation and establish an equivalent relation between the extended general implicit resolvent equation and the extended general mixed quasi variational inequality. Some special cases are also discussed.

This article investigates various transcription techniques for the Legendre pseudospectral (PS) method to compare the pros and cons of each approach. Eight combinations from four different types of collocation points and two discretization methods for dynamic constraints, which differentiate Legendre PS transcription techniques, are implemented to solve a carefully selected test set of nonlinear optimal control problems (NOCPs). The convergence property and prediction accuracy are compared to provide a useful guideline for selecting the best combination. The tested NOCPs consist of the minimum time, minimum energy, and problems with state and control constraints. Therefore, the results drawn from this comparative study apply to the solution of similar types of NOCPs and can mitigate much debate about the best combinations. Additionally, important findings from this study can be used to improve the numerical efficiency of the Legendre PS methods. Three PS applications to the aerospace engineering problems are demonstrated to prove this point.
Recently open data has been spread rapidly in the world include Korea. Accordingly in international trade field open data and using it became a key point to get competitiveness. In this study, the author make an attempt to suggest the way for quality improvement of international trade information by looking for some problems with crating and using the information. Thus, the problems of using information are can be point out as follows. Firstly the range of open data is narrow. Secondly the management of the open data is not conducted properly. Thirdly the suppliers of the open data didn't prepare some investigation system for their data's usability for user. Expansion of the organizations who open data is one way to solve quantitative problem. There are four suggestions to solve qualitative problems. Firstly the guidelines should be established and operated in each organizations respectively. Secondly the criterion of expenses for open data should be arranged among the concerned parties. Thirdly the ability of the manpower and organization who charged in the quality improvement of information should be reinforced both quantitatively and qualitatively. Lastly the system for data usability for user should be equipped in early stages. Finally the author emphasize the establishment of total management system for using open data in international trade is not needed only the efforts of the specific parties but also all parties led by Ministry of Industry, Trade and Energy in order to carry out above suggestions successfully.
A novel three-phase four-wire inverter topology is presented in this paper. This topology is equipped with a special capacitor balance grid without magnetic saturation. In response to unbalanced load and unequal split DC-link capacitors problems, a qusi-full-bridge DC/DC topology is applied in the balance grid. By using a high-frequency transformer, the energy transfer within the two split dc-link capacitors is realized. The novel topology makes the voltage across two split dc-link capacitors balanced so that the neutral point voltage ripple is inhibited. Under the condition of a stable neutral point voltage, the three-phase four-wire inverter can be equivalent to three independent single phase inverters. As a result, the three-phase inverter can produce symmetrical voltage waves with an unbalanced load. To avoid forward transformer magnetic saturation, the voltages of the primary and secondary windings are controlled to reverse once during each switching period. Furthermore, an improved mode chosen operating principle for this novel topology is designed and analyzed in detail. The simulated results verified the feasibility of this topology and an experimental inverter has been built to test the power quality produced by this topology. Finally, simulation results verify that the novel topology can effectively improve the inhibition of an inverter with a three-phase unbalanced load while decreasing the value of the split capacitor.

Small area model provides reliable and accurate estimations when the sample size is not sufficient. Our dataset has an inherent nonlinear pattern which signicantly affects our inference. In this case, we could consider semiparametric models such as truncated polynomial basis function and radial basis function. In this paper, we study four Bayesian semiparametric models for small areas to handle this point. Four small area models are based on two kinds of basis function and different knots positions. To evaluate the different estimates, four comparison measurements have been employed as criteria. In these comparison measurements, the truncated polynomial basis function with equal quantile knots has shown the best result. In Bayesian calculation, we use Gibbs sampler to solve the numerical problems.
The Quality of physical therapy school system has conflicts between physical therpist, and reduces the opportunity of seguential education. So this study was investigated in order to made concrete the problems of educational duality, set up the direction of the school system's improvement, as like the four-year system and recognized the necessity. The curriculums of 13 colleges and 5 universities was analyzed. The curriculum analysis was made up the comparison and the analysis by a liberal arts point, a major point, a clinical practice point, total opening subjects, and so on. The analyzing results were as follows. 1. The average rates of a liberal arts vs. a major opening point are 17:83 in college, and are 27:73 in university. 2. It is a serious problem that college are lower than university in a liberal arts. The best method that can solve it is lengthen the number of school years. 3. There is no difference between college and university in a major subject. Rather college has the more subject's numbers than university. 4. There is no difference between college and university in a clinical practice. Above results suggests that there is not different between college and university in a major subject except for a liberal arts point. It is proper that one should be unificate the curriculum according to the sameness between a state examination and a license. Therefore, it is necessary for graduates from college that provides the opportunity of proceeding to a higher school, demands the seguential system of study cultivating and producing a bachelor, and requires the continual education in a clinical field, a bachelor admitting system of continual education, and clinical therapist's qualification. The present physical therapy educational systems should be unificated because of many right reasons. On the other hand, the follw-up study that improving the school system about the four-years and the more physical therapy should be continue from the viewpoint of education.
Purpose: The study aimed to examine the influence of PNF direct and indirect breathing treatments for patients with cervical spinal cord injuries who had breathing problems. Methods: For each cervical spinal cord patient, force vital capacity (FVC), peak expiratory flow, maximum phonation time (MPT), rib cage width, and VAS were measured pre-intervention and four weeks after post-intervention. The indirect method and the direct method were used for interventions. We treated patients with the indirect method using scapular anterior depression pattern, bilateral extensor pattern with rhythmic initiation, and a combination of isotonic. We treated patients with the direct method, applying pressure on the sternum and using rhythmic initiation (hold relax and stretch reflex) for the rib cage. Training occurred for 50 minutes a day and three days per week for four weeks. Results: FVC, MPT, peak expiratory flow, and rib cage width were increased and decreased at the VAS point for rolling after treatment. Conclusion: Patients with cervical spinal cord injuries who had breathing problems felt uncomfortable when they had conversations on a couch. We found that PNF direct and indirect treatments improved rib cage width and breathing functions of patients with cervical spinal cord injuries.

This study makes clear Huang Yuan-Yu(黃元御)'s medical thoughts Yi-philosophically. Yi-philosophy(易學) since ancient times is occupied by fundamental problems of various fields of Oriental Science. Confusian Medicine Reseachers of Zhang Jie-Bin(張介賓), Zhang Nan(章楠), Zhu Zhen-Heng(朱震亨) was seriously affected by Yi-philosophy(易學) and Confucianism(儒學). But I don't think that the majority of their medicine theories are occupied by Yi-philosophy(易學) and Confucianism(儒學). But Huang Yuan-Yu(黃元御) studied medicine thoughts on the basis of Tu Shu Yi(圖書易) in almost whole medicine theories and clinical contents. Therefore this study researched medical thinkings of Huang Yuan-Yu(黃元御) on Yi-philosophical medical viewpoint Tu Shu Yi(圖書易)-scientifically. Especially in this paper the author examined a characteristic point in medical thoughts of Huang Yuan-Yu(黃元御), the difference of existing medicine on Nei-Jing(內經) and Yi-medicine of Huang Yuan-Yu(黃元御), a commonness of medicine principles of Huang Yuan-Yu(黃元御) and Li Ji-Ma(李濟馬)), medicine theories of Huang Yuan-Yu(黃元御) on Tu Shu Yi(圖書易) and a background of Yi-philosophical medical standpoint. The results was summarized as follows; First, Huang Yuan-Yu(黃元御)'s standpoint on five phase is that the relation of earth and wood fire metal water is form and use(體用). Huang Yuan-Yu(黃元御) insists that the earth represents existence itself and wood fire metal water is concepts that represents actual states. Second, the concept of Four-Constitution of Huang Yuan-Yu(黃元御) and Li Ji-Ma(李濟馬) is same. Third, Huang Yuan-Yu(黃元御) doesn't have a standpoint of five-phase on Nei-Ching Medicine, but a standpoint of five-phase on Yi-philosophy. Fourth, water, fire, metal, wood is Four-Constitution that middle qi transformed. Fifth, the middle qi is yang-earth and yin-earth of the spleen and stomach, the physiological function of four viscera is maintained by the movement of ascending and descending of yin and yang earth. Sixth, The middle qi is main role of Four-Constitution. Exchanging of water and fire and the movement of ascending and descending of metal and wood depends on the earth. Seventh, generally medicine researchers speak that human mind is a main role of psycho-function of heart, but Huang Yuan-Yu has the standpoint of spleen-stomach oriented seven emotions not human-mind oriented viewpoint. It represents that a existing thinking of heart-earth center is changed to medical viewpoint of spleen-earth center. Eighth, There is enough ground for controversy on where is the middle point of human in five viscera. Is that spleen or heart? Huang Yuan-Yu(黃元御) insists that the spleen and stomach is middle point, but the standpoint in Four-Constitution medicine of Li Ji-Ma(李濟馬) is that middle point is heart.
To investigate the risk perception of environmental issues, two consequtive surveys were conducted to environmental professionals using a standardized questionnaire from September to October in 1999. The number of subjects were 72 for the first survey and 68 for the second one. The questionnaire was consisted of items such as the degree of environmental pollution in Korea, risk perception of some issues on human health and ecosystem, and seriousness of the problems in the real situation in Korea. For the degree of environmental pollution in Korea, the average risk rating in the second test (7.4 point) was significantly higher than that in the first test (7.2 point). The risk perception on the general human health and ecosystem, and the seriousness in Korea situation were analyzed in the order of ′air pollution′, ′water pollution′,′soil contamination′,′waste′,′toxic chemical pollutants′,′food contamination′,′ocean contamination′, ′odor pollution′, and ′noise pollution′. Also ′toxic chemical pollutants′ problem was perceived to be the highest risk on general human health or ecosystem, and on present situation in Korea. ′Automotive vehicle exhaust′ problem was perceived to be the most severe environmental problems among specific 30 items. ′Industrial source air pollution′,′toxic air pollutants′, and ′domestic and industrial source pollutants to surface water′ were relatively severe environmental problems comparing to other problems. The pollution issues were classified into four categories by two aspects of perception; risk in general setting and seriousness in Korea situation. If the issues were highly serious in Korea and low risk perception in general setting then it is named "the Korea-specific group". Those that were all high score in two aspects, named "the Common group". Those that were all low in two aspects, named "the Nonsignificant group". And the issues were high risk perception in general setting and low seriousness in Korean situation, named "the Latent group".
