N/A The experiment was carried out for the purpose of studying the carburization of pure iron ingot and sintered iron powder by solid carbon in the atmosphere of CO gas. The volocity of carburization was estimaed by the diffusion coefficient D calculated by carburization equation. The results obtained were as follow: 1. The higher the carburization temperature, carburization depth and carbon concentration were increased, and the melting zone which had 2.8∼3.4%C at the 3∼4㎜ from interface of carburization was formed at 1300℃. 2. The main caxburization mechanism of pure iron ingot and the sintered iron powder were proceeded by CO gas up to 1100℃, solid carbon over than 1300℃, respectively. 3. The main carburization mechanism of pure iron ingot at 1200℃ was proceeded by solid carbon, and sintered iron powder was proceeded bs CO gas, however, in case the reaction time, the carburization was proceeded by solid carbon over than 5hrs. 4. The diffusion coefficient D of carbon were 0.559×10^(-6)㎠.sec^(-1) at 1100℃, 0.237×10^(-6)㎠.sec^(-1) at 1200℃, 0.087×10^(-6)㎠.sec^(-1) at 1300℃, in case of pure iron ingot carburized. 5. The diffusion coefficient D of carbon were 0.124 ㎠.sec^(-1) at 1100℃, 0.102 ㎠.sec^(-1) at 1200℃, 0.480×10^(-6)㎠.sec^(-1) at 1300℃, in the case of sintered iron carburized at the pressuring 4ton/㎠.

Objectives: The aim of this stuty is to investigate the effect of acupuncture at Yanggnungch`on (G34) on the muscle fatigue. Methods: Subjects were asked to perform the elbow flexion and extension to induce the muscle fatigue. Sample group of 16 healthy subjects had acupuncture on Yanggnungch`on (G34) during the resting time, while control group of 13 healthy subjects did not. Surface electromyography (sEMG) was measured after exercise and rest to record muscle fatigue. Results: Acupuncture at Yanggnungch`on (G34) is effective for decreasing the muscle fatigue.

본 연구는 채널 번들링에서 문제가 되는 주제롤 선택하여, 이에 대한수용자들의 응답을 분석함으로써 채널 번들링에 필요한 정보를 도출하였다. 그 결과 첫째, 선호장르의 경우 영화를 가장 선호하는 것으로 나타났다. 둘째, 저렴하지만 다양한 채널상품율 비싸더라도 영화채널을 많이 제공하는 채널상품에 대한 선호도가 높았다. 따라서 일부 채널상품은 티켓 마케팅이 가능함을 확인했다. 셋째, 동일 장르보다는 다양한 장르로 구성 된 채널상품을 조금 더 선호하였다. 넷째, 수신료 지불형태의 경우 메뉴형을 가장 선호하는 것으로 나타났다. 다섯째, 매체별 경쟁력을 보면 저가형 케이블TV 채널상품을 가장 선호하는 것으로 나타났다. 여섯째, 매체나 채널상품을 전환할 의사가 매우 작은 보수적인 형태를 보였다. 마지막으로 지역별 채널 상품에 대한 선호도는 다른 경우가 많았다. 따라서 시장세분화를 고려할 필요가 있다. In this research paper, we have chosen a subject from the channel bundling and by conducting a rigorous analysis on consumer respondence, we have earned the information in need. The results are seven-fold: First, in the case of preference genre study, movie turned out to be the most preferable genre. Second, in the case of investigation on the preferred channel commodity, people tend to embrace a channel commodity that is relatively expensive but provides more movie channels than less expensive one with limitation of channels. This implies that target marketing is available for particular channel commodities. Third, people prefers a channel commodity that incorporates various genres than the one which is consisted of only one genre. Fourth, from various charging methods, the menu layout is most preferred. Fifth is about market competency level of mediums, and in this case, low-cost cable system is most preferred. Sixth, the research shows that people are very conservative in converting a media now in use and that the intention to changing it is very low. Seventh, the preference for local channel commodity turned out to vary in different regions, suggesting that market segmentation should be put into consideration.

The purpose of this paper is to derive and estimate a model of the demand for media based on the assumption that the decision to media is made by producers attempting to minimize the cost of advertising. We employ a translog demand model, whose parameters we estimate by both three-stage least squares and seemingly uncorrelated regression model, based on 1970-2004 annual Korean data. We assess substitute and complementary relationships among four advertising media, as well as the magnitude of their ordinary own-and cross-price elasticities and elasticities of substitution. The estimation results-the estimated elasticities of substitution and the estimated ordinary cross-price elasticities- indicate weak substitutability between media. We find demand by advertisers for each of the four media is own-price inelastic, and that cross-price elasticities suggest slightly more substitute than complementary relationships, although both are rather weak. An important caveat to these results is associated with radio data.

Objective: The purpose of this study was to report a case of a treatment with Scolopendrae Corpus Herbal-Acupuncture for one patient suffering from the Cervical Myelopathy. Scolopendrae Corpus Herbal-Acupuncture has been used as a analgesics and antispasmodics in the oriental medicine and reported to have antiinflammatory effect, sedative action and immunity enhancing activity, on one patient suffering from the Cervical Myelopathy. Methods: TThe patient was treated with Scolopendrae Corpus Herbal-Acupunture, acupuncture, herbal medication. Scolopendrae Corpus Pharmacopuncture was administered two or three times per week and we injected 0.2~1.0 ㎖of Scolopendrae Corpus Pharmacopuncture to the patient`s neck and both arms. The improvement of the symptoms was evaluated by JOA score(Japanese Orthopedic Association score), Nurick grading, VAS(Visual Analog Scale), reflex testing, Finger escape sign, Grip and Release test. Result: After 5 weeks of treatment, the patient`s JOA score, Nurick grading and VAS were improved from 12 to 16, from grade III to grade II and from 10 to 3 respectively. The movement and power of upper and lower limbs were restored to nearly normal range.

Objectives :The purpose of this study is to compare interrelations between stress and muscles of neck through stress response inventory(SRI), 7 zone diagnostic system and surface electromyography(sEMG). Methods :This study was carried out with the data from SRI, 7 zone diagnostic system and sEMG. First subjects were divided into two group according to the SRI points. subjects in group A had points of SRI in which lower than 30 points. Subjects in group B had points of SRI in which higher than 30 points. And subjects were divided into nonstress group(Group C) and stress grouop(Group D) according to the result of 7 zone diagnostic system. Then we investigated how to differentiate the muscle contraction, fatigue, recovery and asymmetry ratio on sEMG for each groups. Results :In this study, the muscle contraction of both upper trapezius muscle and left sternocleidomastoid muscle and left scalene muscle in stress group were higher than nonstress group significantly. And the muscle recovery of left sternocleidomastoid muscle and left scalene muscle in stress group were higher than nonstress group significantly. Conclusions :This results show that the stress was associated with muscle condition.
