The purpose of this case study is to report the effect of oriental medical treatment on chronic tension-type headache. Despite the patient was treated by cervical nerve block for headache, headache was not improved. We diagnosed chronic tension-type headache according to ICHD-II(The International Classification of Headache Disorders) and Qi deficiency, dampness and phlegm by oriental differential diagnosis of symptom and signs. We applied herbal medicine, acupuncture, moxibustion and cupping therapy for hospitalization(7 days). Oriental medical treatment may have effective results in treating chronic tension-type headache that was not improved by cervical nerve block treatment. But this is a single case study, so further case-series research should be compiled.

Comparing with single structure constructed with reinforced concrete or steel, composite structures have a great advantage. However, in case of nuclear power structure, the application of a conventional single structure (reinforced concrete or steel structure) inflicts a heavy loss on a economical and constructive efficiency. But, the application of composite slab to nuclear power structure could compensate these deficiency. Therefore, in this study, the structural behavior of composite slab in nuclear power structure is observed to assure economical and constructive efficiency.

This paper proposes a MATLAB program for solving security-constrained optimal power flow using linear programming. Security-constrained optimal power flow can find an optimal generation satisfying bus voltage limits, line flow limits, reactive generation limits, even if contingency occurs. Sensitivity matrixes are obtained based on power flow solutions with and without single line contingency. This program is tested for an IEEE 14bus system with 5 generators Results shows good ability of finding optimal solution in case of a single line contingency.

This study is designed to find out the effects of price on the consumers'perceived quality, value and purchase willingness of clothing in order to get the basic information that is needed in helping clothing manufacturer's strategy for merchandising promotion on price. This study was conducted by means of a questionnaire survey of university students in seoul. SAS program was used for analysis. The conclusions of this study as follow: first, with respect to the price level of clothing, consumers evaluate the perceived quality of high-price case higher than that of low-price case, and evaluate the perceived value and purchase willingness of low-price case higher than those of high-price case. Second, with respect to the brand name level of clothing, consumers evaluate the perceived quality, perceived value and purchase willingness of well-known brand case higher than those of unknown brand can. Third, the interaction between price and brand dosen't appear. Thus from this result we can know that price and brand have the same amount of effect in both single-quo case and multi-que case. Forth, with respect to the price and brand name level of clothing, there exist significant differences in perceived quality, perceived value, and brand name level. Fifth, in the study of the relationship between perceived quality and purchase willingness and the relationship between the perceived value and purchase willingness, perceived value has more effect on purchase willingness than perceived quality.

This study deals with the roundabout installed at the diamond interchange. The goal is to analyze the relative effectiveness of roundabout to signalized intersection. In pursuing the above, this study gives the particular attentions to comparing the performances using VISSIM software. The main results analyzed are as follows. First, the single and double roundabouts are analyzed to have the rapid change of delay in the case of total entering vehicles of more than 2,400pcph for directional rate 10:5:5, 2,800pcph for 10:8:2, and 4,400pcph for 10:2:8. Second, the roundabouts are evaluated to be more effective than signalized intersection in the case of total entering vehicles of less than 4,000pcph for directional rate 10:5:5, and 4,400pcph for 10:2:8. In the case of directional rate 10:8:2, double roundabout of total entering vehicles less than 5,600pcph is analyzed to be more effective than signalized intersection. Finally, the performance of double roundabout is analyzed to be very similar to that of single roundabout in the case of total entering vehicles less than 4,400pcph. However, the double roundabout is evaluated to be more effective than single in the case of total entering vehicles more than 4,400pcph.

This study examines the effect of goal setting training during psychological skills training on improving the happiness of actors using a single case study design. The subject of this study was a famous actor in his late 40s who had received personal psychological training from this researcher, a sports psychological counselor, to strengthen his psychological capabilities. The goal setting training program consisted of 8 sessions of 60~90 minutes each. For the purpose of this study, pre and post tests were conducted using the Oxford Happiness Scale developed by Argyle (2005), and in-depth interviews were also conducted. As a result, goal setting training had a positive effect on improving the happiness of actors.

The purpose of this study is to determine the concepts of heterotopic image and fashion space, and the characteristics of fashion space and images from the perspective of fashion brands and users. This study examines the evolution of fashion space and consumers with it, based on Foucault's theory of heterotopia, which refers to spaces that blend contradictory features not typically found within a single physical structure. This is accomplished by employing a single case study of Ader Error's Ader Space, a Seoul-based brand known for its unique approach to presenting and communicating fashion. Based on an analysis of Instagram posts of Ader Error along with the hashtag searches "aderspace" and "adererror", this study categorizes heterotopia from the perspective of fashion brands into three properties: fashion space as a medium for selling fashion products; fashion space as getaway to hybrid fashion practices; and fashion space as an illusionary place to experience fashion. From the user perspective, the heterotopic image of Ader Space portrayed on Instagram is characterized by the image of fashion products in an extraordinary fashion space, the image of a fashion space beyond space and time, and the image of exposing the hidden and the illusion-compensation of fashion space. This study contributes to a heightened understanding of the evolutionary concept of the fashion space.

Strategic agility plays an important role in maintaining a competitive advantage for companies, where information systems are introduced. The purpose of this study is to analyze the impact of the introduction of the information system on the strategic agility of the company through the analysis of the "H" resort, which has recently built the information system. Research shows that the introduction of resort management information systems promotes the level of strategic sensitivity, collective commitments and resource liquidity, which are key elements of strategic agility. This study confirmed that the establishment of resort information system has a positive effect on practitioners who want to create strategic agility. However, this study is a single case study and it is difficult to argue that the introduction of information systems is a positive for the strategic agility approach.

The purpose of this paper is to diagnose the errors by comparing putting motion with the single pendulum pattern applicable to putting in golf skill and order prescription that correct errors of putting. In the modern-day game of golf, putting remains the key to shooting low scores, and the ability to hole putts can turn a good round into a great round A semi-golfer, subject(sex female, age 20yrs, mass 94.3kg, height 1.65m) who has troubles to do putting is chosen. Six cameras, ProReflex MCU240(240Hz) made by Qualisys company is used to capture putting motion and data is processed by QTM(Qualisys Track Manager) and Mathematica 5.0. The result that differentiates the putting and the single pendulum pattern is acquired To make the pattern of subject's putting to the single pendulum pattern quasi-equal, one tries to lower center of mass gradually. As a result of it, one has a similar pattern like the single pendulum Conclusively, to lower C.O.M one orders prescriptions that increase the weight and length of a putter and lower C.O.M subject's segment. Further improvements to the study could be to train a subject according to prescriptions and to monitor putting again. It will probably be necessary to simulate putting motions and to research relations for body shapes and putting patterns in order to establish suitable putting-motions.
