The main symptoms of allergic rhinitis are sternulation, rhinorrhea and rhinanchon. It is also characterized by frontal headache, ohotophobia and epiphora. Alleric rhinitis occurs when inhaled alleren is in contact with nasal mucosa which causes immune response. Bojungiki-Tang is one of the most frequently used medical treatment for the allergic rhinitis. Two chronic perennial allergic rhinitis sutterers, whose alleraies are thought to be due to house dust and ticks, were investigated through the eosinoohil numerical index and the subject symptom numerical index for three months. After treatment, both patients showed a lower index for both tests. The symptom index scores diminished from 17 to 3, and from 16 to 5. The eosinophil numerical index taken through blood tests, diminised from 4 to 2, and from 4 to 3. The above results suggest that Bojungiki-Tang has the inhibitory effects on allergic rhinitis.

With the advent of high speed digital signal processing chips, new digital techniques have been introduced to the hearing instrument. This advanced hearing instrument circuitry has led to the need or and the development of new fitting approach. A number of different fitting approaches have been developed over the past few years, yet there has been little agreement on which approach is the "best" or most appropriate to use. However, when we develop not only new hearing aid, but also its fitting method, the intensive subject-based clinical tests are necessarily accompanied. In this paper, we present an objective method to evaluate and predict the performance of hearing aids without the help of such subject-based tests. In the hearing impairment simulation (HIS) algorithm, a sensorineural hearing impairment model is established from auditory test data of the impaired subject being simulated. Also, in the hearing impairment simulation system the abnormal loudness relationships created by recruitment was transposed to the normal dynamic span of hearing. The nonlinear behavior of the loudness recruitment is defined using hearing loss unctions generated from the measurements. The recruitment simulation is validated by an experiment with two impaired listeners, who compared processed speech in the normal ear with unprocessed speech in the impaired ear. To assess the performance, the HIS algorithm was implemented in real-time using a floating-point DSP.

Current fire design codes for determining the temperature within the structural elements that form part of a complete building are based on isolated member tests subjected to the standard fire. However, the standard time-temperature response bears little relation to real fires and doesn't include the effects of differing ventilation conditions or the influence of the thermal properties of compartment linings. The degree to which temperature uniformity is present in real compartments is not addressed and direct flame impingement may also have an influence, which is not considered. It is clear that the complex thermal environmental that occurs within a real building subject to a natural fire can only be addressed using realistic full-scale tests. To study global structural and thermal behaviour, a research project was conducted on the eight storey steel frame building at the Building Research Establishment's Cardington laboratory. The fire compartment was 11 m long by 7 m wide. A fire load of $40kg/m^2$ was applied together with 100% of the permanent actions and variable permanent actions and 56% of live actions. This paper summarises the experimental programme and presents the time-temperature development in the fire compartment and in the main supporting structural elements. Comparisons are also made between the test results and the temperatures predicted by the structural fire Eurocodes.

This paper aims to discuss the effects of learning how to write English interrogative sentences. 122 students who participated in the study learned basic structural components of English questions and practiced writing questions by inversing the subject and the verb in a given declarative sentence. The participants were divided into two groups: Group 1 which was given a brief explanation of interrogative structures and practices, and Group 2 which was given the same explanation and practices in addition to an assignment for which they had to make one or two comprehension questions based on reading a passage. For the pre-tests and the post-tests, they took a TOEIC reading test with 40 questions and a structure test with 25 questions. The results of the tests show that both groups improved significantly in the two post-tests, benefiting from this learning method. However, the additional treatment for Group 2 did not seem to be highly effective. In the questionnaire survey, the participants think that the method of learning English questions has helped them better understand English grammar as well as interrogative structures. The participants were also divided into three different levels: high, intermediate, and low. The intermediate level group students benefited most from learning writing questions as the results of the post-test of the 25-questions test and the final exam of the course show.

The biogas holder is composed of an outer membrane and an inner membrane which are subject to outdoor exposure and gas exposure respectively. The influence of weathering conditions on the photo-degradation of a biogas holder was investigated. Tests were performed under three different methods - outdoor exposure tests (Seosan, Arizona), accelerated tests (Xenon-are lamp) with the outer-membrane of biogas. Moreover, the changes in the aging process were monitored using color difference, gloss, the contact angle and an optical microscope. Changes in physical properties, such as decrease reduction in gloss, decrease in the contact angle, increase in color difference were observed in the aging process. The comparison between membrane 3B, 4B and membrane 5B under xenon-arc were discussed. Membrane 5B was very sensitive to ultraviolet (UV) ray. There were many difficulties in the outdoor exposure test due to acid rain, dust, and stain resistance.

In today's mass production/consumption society, there are many important constituents people need to have/do for their happy life. Very few People think that among those components enjoying Pro-sports in their life is essential, and Many business companies are interested in owning/operating pro-sports teams. Thus, many studies have been progressed on sports management or sports marketing domestically and abroad. This paper studied the preference relationship between subject's majors and products/service and pro-sports. We constructed hypotheses about the relationship and tested them by using ANOVA and Tuckey tests. We found significant results that preference for coke/cider is influenced by subject's majors, and that preference for pro-baseball, pro-football, and pro-basketball is also influenced by subject's major, etc. As the results, we can have important information about who are the most important customers and who should be target customers for marketing and promotion, and with the information related business companies can attain higher profitability and less loss through more effective sports marketing.

The purpose of this study was to investigate the effect of watsu therapy on muscle tone in adult hemiparesis patient after stroke. The subject was a 66 year old patient with left hemiparesis whose self gait was independent with minimal assist. The subject was ambulatory with some degree of limitation and demonstrated a little tremor and asymmetry in the body. A multiple treatment design(A-B-C-B) for a single-subject research was used for this study. The watsu therapy consisted of basic moves, head cradle, underfar leg, near leg cradle in watsu I (transition flow), for 25 minutes, which lasted 12 sessions for a total 21 sessions. A baseline was conducted for a first time and a general ROM exercise was conducted after the first watsu therapy. Tone assessment scale was tested : 1. posturing at rest 2. response to passive movement 3. associated reaction Comparing to the baseline and general ROM exercise, The results showed that the watsu therapy had some positive effects on improvement of three tests and there was a more positive effects of both response to passive movement and associated reaction.
