First I chose a patient group and a comparative group composed of 23 members each. Then the body temperature differences in these groups was taken with D.I.T.I. The results are as follows. 1. Average body temperature of the Hwa-Byung patient group is $36.6^{\circ}C$ and that of the comparative group is $36.4^{\circ}C$. So there is no meaningful body temperature difference. 2. The hwa-Byung patient group has higher temperature than the comparative group by ${\triangle}T>1.0^{\circ}C$ at the following acupunture points in these body parts upper and lower, left and right, anterior and posterior, trunk and limb. Especially, the body temperature difference was clear in the CV-17 (jun-Joong) and the GV-4(Myung-moon). 3. When the body temperature was compared in the upper and lower part of the back, it had meaningful differences at the upper and lower acupunture points of the back in the Hwa-Byung patient group but not in the comparative group. 4. When the body temperature was compared in the left and right part of the body, its average difference was ${\triangle}T>1.0^{\circ}C$ in the two groups and the result were meaningless. 5. When body temperature was compared in the anterior and posterior part of the body, its average difference was ${\triangle}T>1.0^{\circ}C$ in the two groups and the result were meaningless. 6. When body temperature was compared in the trunk and limb part of the body, its difference in the patient group was meaningful compared with the non-patient group. From the above results, I think that D.I.T.I. could be used to objectively visualize heat sensation of the Hwa-Byung patients and make an objective concept of Han Yul in oriental medicine.

This paper represents modeling and optimization techniques for solar cell process on single-crystalline float zone (FZ) wafers with high efficiency; There were the four significant processes : i)emitter formation by diffusion, anti-reflection-coating (ARC) with silicon nitride using plasma-enhanced chemical vapor deposition (PECVD); iii)screen-printing for front and back metallization; and iv)contact formation by firing. In order to increase the performance of solar cells, the contact formation process is modeled and optimized. This paper utilizes the design of experiments (DOE) in contact formation to reduce process time, fabrication costs. The experiments were designed by using central composite design which is composed of $2^4$ factorial design augmented by 8 axial points with three center points. After contact formation process, the efficiency of the solar cell is modeled using neural networks. This model is used to analyse the characteristics of the process, and to optimize the process condition using genetic algorithms (GA). Finally, find optimal recipe for solar cell efficiency.

PURPOSE: This study examined the effects of a horse riding simulator, gym ball, and McKenzie exercises on back pain and static balance. METHODS: Among 30 participants with chronic back pain and more than 5 points of ODI, 28 participants were selected. Groups of performing either horse riding, gym ball, or McKenzie were chosen randomly to work out two times a week for six weeks. The static balance was measured using a gym plate and the degree of pain was measured by the VAS and K-ODI. RESULTS: When each exercise was applied to back pain patients, the VAS was changed in all three groups but only in the gym-ball exercise group. The K-ODI varied in all three groups but not in the gym-ball exercise group, In the anterior - posterior static balance, all three groups showed changes, but only the riding exercise group was not significant. In the left-right static balance, all three groups were significant. CONCLUSION: This study showed that six-week exercise for back pain patients was effective in improving back pain and balance ability. Continuous exercise minimizes the risk of recurrence and is effective in preventing and treating back pain.

On last year's KSR conference, the general of systems engineering technology was introduced on the focus that the SEMP(Systems Engineering Management Plan) being applied for a national project of 'Urban Maglev Program'. Since this SEMP covers very wide work scopes of 'plan, application, control of the program', 'design, analysis, test & evaluation of the system', and 'special engineering activities', it is very important that the tasks and responsibilities of all participants of the project, involving the tasks to collaborate between them, are clearly defined and described. By the point, the updating of SEMP should be done continuously. In this paper, the updating points and typically the management plan of TPM (Technical Performance Measurement), which is more concretely defined, will be explained.

The following conclusions are induced from a study on the acupuncture therapy depending on hyungsang of the persons. The study is made on the basis of 'Internal classic (內經)& and &Clinical Lectures by Dr. Jeesan&. The acupuncture originated from the treatment of spasm with numbness in the southern area. The acupuncture is basically a remedy for the exterior disease of meridian but also it can be a cure for the interior disease of Jang and obstinate disease with accurate method. Three mechanisms of acupuncture are described in 'Internal classic'. The first is to make meridian circulate smoothly. The second is to regulate Ki and Hyul. The third is to regulate points through which the meridian-Ki goes in and out smoothly or adversely. There are two ways of acupuncture in 'Internal classic'. One is based on pulse and symptom and the other on the Hyungsang. The former is more generally used therapy, to which depletion method, Asi point method(阿是穴 療法), Inyoung-kigu pulse comparison method (人迎氣口脈法) and method depending on jang-bu disease belong. Acupuncture is done on Su points(輸穴) and back-su point(背兪穴) in case of jang-disease. In case of bu-disease, the treatment is done on Hap points(合穴) and Mo-points(募穴). The latter includes two methods; one according to invariable Hyungsang. And the other to variable Hyungsang. The method of acupuncture according to invariable Hyungsang usually selects Won-points(原穴). Different Hyungsang requires different method of acupuncture; In case of Dam type, the acupuncture is mainly practiced on four-Kwan points with reinforcing and reducing methods achieved by the direction of the needle tip pointing to. In case of Bangkwang type, the acupuncture is usually done on Jungwan(中脘) and Poongyung(豊隆) with reinforcing and reducing methods by means of respiration. In case of female, more effective are the acupoints on the right and lateral parts of the body selected on the basis of five su-points of the twelve meridians matching the heavenly stems and earthly branches. In case of male, more effective are the acupoints on the left, front and rear parts of the eight extra meridians. In case of acupuncture to the person with Hyungsang of five jang and six bu, each person's intrinsic Hyung, color, pulse, must be observed. Because symptoms of jang-bu disease also must be checked up. Acupuncture is done on the Won-points of the meridians related to the jang and bu where the disease starts. The disease of five jang is so obstinate that it requires both of medication and acupuncture for a long time. In case of acupuncture to the person with Hyungsang of animal types, diagnosis is made on the basis of shape, temper, function and color. And the treatment is given on the Won-points of corresponding exterior and interior meridians. For the fish type, the acupuncture is done on the kidney meridian of foot-soyin and the urinary bladder of foot-taiyang. For the bird type, on the heart meridian of hand-soyin, the pericardium meridian of hand-gualyin, and the small intestine meridian of hand-taiyang For the deer type, on the liver meridian of foot-gualyin and the gallbladder meridian of foot-soyang. For the turtle type, on the lung meridian of hand-taiyin and the large intestine meridian of hand-yangmyung.

This study presents the estimates of heritabilities of body measurement traits and carcass traits, and genetic and phenotypic correlations of those traits for crossbred pigs in Korea. Body and ultrasound (A mode: Piglog 105) measurements in 221 pigs including body weight, length, height and width, three back fat thickness at the points of 4th, 14th rib and chine bone, eye muscle area and lean meat percent were collected at the ages of 70, 145 and 180 days and then slaughtered to measure carcass weight, back fat, belly, collar butt, spare rib, picnic shoulder, hind leg, loin, tenderloin, lean meat yield and intramuscular rough fat content in loin. Genetic analysis was done using a multi-trait animal model. Heritabilties of the body measurements were ranged from 0.331 to 0.559 and three measurements of back fat thickness were also high as range varying from 0.402 to 0.475 for the ages of 145 and 180 days. However, eye muscle area was moderate (0.296) at the age of 180 days. Heritabilities of retail cut yields were also high as ranged from 0.387 to 0.474 and of IMF content in loin was 0.499. Heritabilities of the cut percent traits were ranged from 0.249 to 0.488. Important positive genetic and phenotypic correlations were noted for all carcass yield traits (0.298 to 0.875 and 0.432 to 0.922, respectively). IMF showed low negative genetic correlations with carcass yield traits, such as carcass weight, picnic shoulder, hind leg, loin, tenderloin and lean meat yield whereas low positive genetic correlations with back fat, belly, collar butt and spare rib. Loin, tenderloin and lean meat percent showed negative genetic correlations with carcass weight, back fat thickness, collar butt, spare rib and picnic shoulder percent. The four body measurements at the ages of 70, 145 and 180 days had positive genetic correlations with belly, shoulder butt, spare rib, picnic shoulder and hind leg percent, but negative genetic correlations were shown with loin and tenderloin percent except body measurements at 70 days. The results suggest that carcass yield are negatively correlated with intramuscular fat content, which is a major factor deciding pork quality and the yield of loin and tenderloin are not increased as much as increase in body size. However, the proportions of belly and collar butt are increased with the body size. In conclusion, selection strategy should be designed according to the preference on composition of carcass in each country.

Pulse-feeling took its origin from making a diagnosis along meridians in the course of discovering and forming meridians and for a long time its meaning was mixed with meridians in the course of recognizing "The Pulse" then was separated from meridians in the early days of Western Han Dynasty. Ancient pulse-feeling methods are pulse-feeling method by the twelve regular meridians, pulse-feeling method by three regions and nine modes, pulse-feeling method by Inyeong(人迎) and Chon-gu(寸口), etc. Pulse-feeling was changed in proportion to diagnostic purpose and method of treating and if method and region of pulse-feeling is arranged, we will infer correlation between meridians and pulse-feeling and will infer transitional system of past pulse-feeling and will forecast transition of future pulse-feeling. As the result that I study the transition of the above three pulse-feeling methods of meridians diagnosis: 1. Three pulse-feeling methods of meridians diagnosis flowed into diagnostic method by taking pulse of setting six region for Chon(寸), Gwan(關) and Cheok(尺), i.e. the Chon[寸] spot pulse of $\ll$Nan-gyeong$\gg$ and were changed into diagnostic method being fit for use of five Su points, The Front-Mo points and Back-Su points that grasp the pathology of mutual internal organs and treat the disease. 2. Today it is suggesting the transition of another pulse-feeling method that do not apply diagnostic method by taking pulse of setting six region for Chon(寸), Gwan(關) and Cheok(尺), i.e. the Chon[寸] spot pulse of $\ll$Nan-gyeong$\gg$ to 19C Sasang(四象) Constitutional Medicine or 20C Eight Constitutional Medicine.

The following are the results from the infrared body temperature image test to verify the changes in facial temperature according to call duration with a cellular phone. As for the body temperatures, it appears to be the mean value at the upper central point of phone's battery among 7 different points that are measured, and to be the highest at srernocleido-mastoid and scapular trapezius muscle triangle zone$(34.25^{\circ}C\; and\;34.05^{\circ}C\;each)$. The changes of body temperature according to the time duration shows that the body temperature rises according to the length of phone use because of the heat emitted from the battery. As for the temperature changes according to blocking materials, the one without processing appears to be higher in the mean temperature compared to the others that are processed, NSS(Nano Silver Silk) and NSG(Nano Silver Silk Gold) appear to be the lowest in the temperature to show the best blocking property. As for the temperature changes according to measuring points, it appears to be the highest at P4, P5 with all materials, and one with NSG to be the lowest at Pl, P2, P3, and one with NSS to be the lowest at P3, P4, P5, P6, which is due to the thermal conduction of Au and Ag. And the mean temperature at each point appears to be different according to the materials. Therefore, the study conducted with human participants requires a proper particle size of it which would not penetrate cellular tissues and a proper binder and binding treatment for it, to prevent the physical fatigues and the potential diseases. However, it is highly required for back-up researches to verify various aspects in applying nano silver to textile products.

각질세포의 배양법이 개발 후 피부 결손 부위의 치료에 인체 각질세포를 배양하여 얻어진 표피를 이식하는 방법부터 세포부유물을 도포하는 방법들은 Trypsin 처리 과정을 거치면서배양된 세포의 부착능력을 가진 단백질이 손상되어 성공적인 피부 재생이 불가능하다. 본 실험에서는 이러한 효소처리의 단점을 보완하기 위해서 고분자 미립구에 세포를 효소처리 과정없이 동물실험을 한 결과 21일 후에는 대조군에 비해서 표피가 완벽하게 재생되었고 이식 후 세포의 부착면적을 늘리고 생착율을 높일 수 있었다. 이 연구에서 효소처리 없이 고분자 미립구에서 배양된 세포를 이용한 인공피부 재생이 효과적인 것을 보여주었다. 이러한 모델은 앞으로 화상이나 궤양으로 인한 피부 손실 부위 치료에 사용될 수 있을 것으로 생각된다.
