Subjects : We tried to analysis dermatosurgical prescriptions including 477 WonBang(元方) prescriptions for SangJungHaTong(上中下統) introduced by HwangDoYeon(黃道淵). Methods : Prescriptions in BangYakHapPyun(方藥合編) is generally categorized into SangTong(上統), JungTong(中統), HaTong(下統) which are called PoJe(補劑), HwaJe(和劑), KongJe(功劑) respectively. This study classified and analyzed major diseases and symptoms appeared in dermatosurgical prescription and composition of medicine, as well as in BangYakHapPyun(方藥合編). Results and conclusions : The results of examining dermatosurgical prescriptions in WonBang(元方) of SangJungHaTong(上中下統) in BangYakHapPyun(方藥合編) are as follows; 1. The proportion of dematosurgical prescriptions was SangTong(上統) $\frac{10}{126}$(7.9$\%$). JungTong(中統) $\frac{22}{181}$(12.1$\%$), and HaTong(下統) $\frac{16}{163}$(9.8$\%$), which means that JungTong(中統)(HwaJe 和劑) takes up relatively the largest portion. 2. As for SangTong(上統), upper level herbs used in medicine are Glycyrrhiza uralensis(甘草), Paeonia japonica(白芍藥), Angelica gigas(當歸). Astragalus membranaceus(황기). Ginseng(人蔘), Poria cocos(복령), Atractylodis macrocephalae rhizoma(白朮). Cinnamon(肉桂), Rehmaniniae radix preparat(熱地黃). And these herbs are the components of Sipjundaebo-tang(十全大補湯), one of the most well-known medicine for weak energy and blood(補氣血). 3. As for JungTong(中統), in addition to medicine for weak energy and blood. Ledebouriella seseloides(防風) that removes ill elements on skin surface and Pung(風) called "wind". Limonium tetragonum(桔梗) that eliminates discharges and sputum, Angelica dahurica(白芷) that removes discharge and suppress tumor are applied. Other herbs are Ostericum koreanum(羌活). Skullcap(황령),Schizonepeta tenuifolia(荊芥), Aurantii fructus(地殼), Cimicifuga heracleifolia(升麻), Bupleurum falcatum(柴胡), Lonicerae flos(金銀花). These herbs are more effective for wind-calming treatment. cooling down fever, clearing skin irritation, detoxication. removal of tumor and discharge than replenishing energy and blood. 4. As for HaTong(下統), Angelica gigas(當歸) and Ledebouriella seseloides(防風), the two major herbs for SangTong(上統) and JungTong(中統), are mostly used. In addition, Skullcap(黃芩), Gardenia jasminoides(梔子), Eisenia bicyclis(大黃) are other major components and their key efficacy is to lower fever and KongHa(功下). 5. Herbs applied for SangTong(上統), JungTong(中統), and HaTong(下統) in large quantity are Glycyrrhiza uralensis(甘草) that harmoniously combine different herbal elements and Poria cocos(복령) that discharges humidity and watery elements out of body, removes humid and hot elements, and strengthen gastrointestinal system. Based on this, it is inferred that prescriptions for this study focus largely on treatment of humid and hot elements. In the composition of this prescription, Angelica gigas(當歸), Paeonia japonica(白芍藥), and Cnidium officinale(川芎) are taking up relatively large proportion, which are basic herbs for Samul-tang(四物湯). Therefore, it is incurred here that the concept of "replenishing blood" bears importance in dermatosurgical treatment. 6. As for herb medicines used for more than two types of prescriptions of SangTong(上統), JungTong(中統), and HaTong(下統), most of them are simultaneously used for SangTong(上統) and JungTong(中統), or for JungTong(中統), and HaTong(下統) except for Atractylodis macrocephalae rhizoma(白朮) and Gleditsia sinensis(조각자). This finding implies that prescription or treatment that are simultaneously applied are replenishing and harmonizing, or harmonizing and attacking while replenishing and attacking never go together.

Objectives: This study was conducted to investigate the determining factors that have influence on elementary students who go without breakfast and identified their physical, mental and social health that may resulted by skipping breakfast. Methods: For data collection, total 855 elementary students at the 5th and 6th grade in an urban and a rural area were asked to join the survey using a self-administered questionnaire from March 25 to April 9, 2005. The data were analyzed through a series of statistical methods including frequency, percentage, chi-square$(X^2)$ test, t-test and multiple logistic regression analysis. Results: It was found that 24.0 % of respondents would skip breakfast, and influential socioeconomic factors on their skipped breakfast were economic level and mother's occupation. A group that has meals more with family everyday and a group that has breakfast served by mother as usual showed significantly low percentage of going without breakfast at statistical level(p<0.05). In case that other family members used to go without breakfast, there was a tendency to significantly high rate of skipped breakfast(p<0.01). And a group who got up early in the morning and a group who scored high points in the assessment of dietary habit showed significantly low percentage of skipped breakfast(p<0.01). In the result of multiple logistic regression analysis, the significant variables in urban area were economic level, person setting up breakfast, getting-up time and family members who would skip a meal. In rural area, meal-skipping family member, person setting up breakfast and dietary habit were significant variables(p<0.05). In physical influences according to skipping breakfast, students would skip breakfast had more stomach or dizziness(p<0.05). Depression score were higher and school life score were lower in group skipping breakfast, but not statistically significant. Conclusions: In conclusion, in order to reduce the rate of elementary students who often go without breakfast, it is favorable that they should be instructed in the importance of breakfast and the harm of skipped meal, so that they can cultivate positive living habits and dietary attitudes as well. And it is necessary that this health education cover not only students but also all of their family members(especially mother). Furthermore, it is necessary to develop systematic programs for them to get over environment factors.

Purpose: This study was conducted to determine the effects of ankle joint position during closed kinetic chain (CKC) exercise on knee extensor strength and balance in patients with chronic stroke. Methods: Sixteen patients with chronic stroke participated in the study. Participants were randomly assigned to two groups: $15^{\circ}$ ankle joint plantar flexion group (n=8) and ankle joint neutral group (n=8) during CKC exercise. All participants underwent conventional physical therapy for 30 minutes. In addition, the experimental group ($15^{\circ}$ ankle joint plantar flexion group) and control group (ankle joint neutral group) participated in a 20-minute CKC exercise program. In both groups exercise was performed three times a week for four weeks. Outcomes including knee extensor strength and balance ability (Five times sit-to-stand test, Timed up and go test, and Balancia) were measured before and after exercise. Results: Significant differences in knee extensor strength and balance ability were observed between pre- and post-exercise in all groups (p<0.05). The improvement of knee extensor strength and dynamic balance was significantly higher in the experimental group than in the control group (p<0.05). Conclusion: These findings demonstrated that $15^{\circ}$ ankle joint plantar flexion during closed kinetic chain exercise is effective in improvement of knee extensor strength and dynamic balance in patients with chronic stroke.

Intelligent Peripheral(IP) system is to provide specialized resource functions (SRF) such as playing announcement, collecting user information, and receiving messages in the Advanced Intelligent Network (AIN). We analyze the call processing capacity of an AIN IP system being developed in ETRI through an extensive simulation using SLAM II under a variety of AIN service scenarios. We consider televoting (VOT) and universal personal telecommunication (UPT) services which are to be provided at the fit implementation of the AIN in Korea. As the performance criteria to determine the call processing capacity, processor utilization, delay and call loss probability are considered. It turns out that the major processor called SAMP is the bottleneck processor, the service response delay dominates the delay performance, and the call loss probability becomes the primary criterion in determining the call processing capacity of the AIN IP system. It is also shown that the call processing capacity of the AIN IP system is determined by the utilization of the processor and the delay performance when the VOT ratio is below 70 percent but it is determined by the call loss probability due to the lack of service channels for providing the SRF operations.

The Friction Stir Welding (FSW) is a new joining method that was developed at The Welding Institute (TWI) in England in 1991. It applied heating by the rotational friction and material plastic flow. It was developed as a new joining method to solve the problems of epochally in the welding of Al alloys. In the study, 6000series of Alloy composed of AI-Mg-Si, one of the Al alloys that are utilized for shipbuilding and construction, is selected as a specimen and the numerical is executed against the welded zone of FSW. The material used in this study had the unique properties of strength and anti-corrosion, but since the welded joint of this material is easily softened by the welding heat, FSW is executed and the numerical analysis is carried out around the joint. To examine the mechanical behaviors and properties, F.E.M analysis is executed and the developed thermal-elastic-plastic [mite analysis are used.

We propose a new frame length control scheme for cognitive radio systems. In the proposed algorithm, the property that the probability of a primary packet arrival continually increases as time elapses during the primary user's idle period is utilized. When reducing the secondary frame length in accordance with the increasing primary packet arrival probability, spectrum sensing is conducted more frequently as time elapses and the primary packet arrival is detected more quickly. We obtain the optimal frame lengths by maximizing the secondary throughput while satisfying the interference constraint. Numerical results show a significant throughput enhancement via the frame length control.
