We have studied the clinical application of burning acupuncture by examining 18recent-published papers in the journal 'ZHONGGUO ZHENJIU(中國鍼灸)' for the bibliographical study and clinical study and have given medical treatment of burning acupuncture on 21 Patients who suffered 'the body chill symptoms(冷症)' at the oriental hospital of Won-Kwang University, Kwang-Ju. As a result, we have come to some conclusions as below. 1. The diseases for which the modern borning acupuncture is efficacious are widely extended to various kinds of field such as surgery, internal medicine, gynecology, ophthalmology, otolaryngology. etc. as well as numbness, meridian muscle disease(經筋病) mentioned in 'Neijing(內徑)' . 2. The effects of burning acupuncture therapy are wen zhuang yang qi(溫壯陽氣), sheng ji lian chuang(生肌斂瘡), san han chu shi(散寒除濕), qu fens zhi yang(祛風止痒), qu yu chu fu pai nong(祛瘀除腐排膿), san jie xiao zhong(散結消腫), zhi tong huan ji chu ma mu(止痛緩急除麻木), qing re xie hue jie du(淸熱瀉火解毒). 3. The recently reported diseases for which burning acupuncture is good are internal and external humeral epicondylitis, atheroma, menorrhalgia, thecal cyst, tragomaschalia, pruritus, traumatic onychophemia, gout of feet, prostatomegaly, aacne, supprative infection of body surface, snapping finger, backache, numbness, pyocyst etc. 4. The subjective symptoms of 'the body chill symptoms(冷症)' were, most of all, feeling cold accompanied by pain(16 case), while just 4 cases were feeling cold only. 5. In the related diseases of the body chill symptoms(冷症), feeling pain like arthralgia was the most case, and then dysmenorrhea, menorralgia, depression, anemia in order. 6. In the D.I.T.I before and after burning acupuncture treatment, 6 patients had shown 'excellent' effects and 8 patients had turned out 'good', while 7 patients had become'fair'. 7. In the degree of patient-satisfaction, 5 patients announced 'excellence' and 6 patients expressed 'good', 4 expressed 'fair', while the other 6 showed no change. 8. In the correlation of D.I.T.I and patient-satisfaction, the better the result of clinical treatment was, the more satisfied the patient was, however, in the case 'fair', we saw the degree of patient-satisfaction was relatively low, so we could admit the judging significance of D.I.T.I.

시멘트계 기질을 사용하는 복합재료는 재료 양생 과정에서 발생하는 건조수축 균열에 취약하다. 본 연구에서는 파이버 보강 콘크리트의 건조수축에 의한 파괴 거동을 시뮬레이션 하고, 파이버의 조건이 균열 특성에 미치는 영향에 대해 분석한다. 수치 해석 모델은 무작위 격자 형태의 기하학적 구조를 공유하는 관로 요소와 rigid-body-spring 요소로 구성되는데, 각 요소가 담당하는 비역학적-역학적 거동의 커플링에 의해 건조수축이 표현된다. 파이버 보강을 모델링하기 위해 rigid-bodyspring network 내부의 semi-discrete 파이버 요소를 적용하였다. KS F 2424 자유 건조수축 실험을 해석하고 시간에 따른 건조수축 변형률 변화를 비교함으로써 재료의 건조수축 관련 계수들을 산정한다. 다음으로 여러 파이버 혼입률에 대해 KS F 2595 구속 건조수축 실험을 시뮬레이션 하고 균열 발생 일자를 선행 실험 결과와 비교하여 해석 모델의 타당성을 검증한다. 또한, 파이버의 길이와 표면 형태를 변화시켜 건조수축 균열 해석을 수행하고 최대 균열 폭을 측정하여 시뮬레이션에서 나타나는 균열 제어 효과를 판단한다.

Physiological Cost Index (PCI) of walking has been widely used to predict oxygen consumption in healthy subjects or patients. The purpose of this study was to evaluate the predictability of physiological cost index of walking for the amount of exercise and cardiac function. Walking exercise was conducted in 67 healthy children (age 4-12) with a self-selected comfortable walking speed on the level surface. Walking speed was calculated, and heart rate was measured before and immediately after the walking. PCI was calculated for statistical analysis. The results were as follows; 1) The walking speed tends to increase and PCI of walking tends to decrease with age. There was significant difference in walking speed and PCI of walking among three age groups (p<.05). The change of walking heart rate tends to decrease with age, however, there was no significant difference among three age groups. 2) Linear regression equation between walking speed and age was 'Y (walking speed) = 2.124X (age) + 48.286' ($R^2$=.337), (p=.00). 3) The walking heart rate tends to decrease with age. Linear regression equation between walking heart rate and age was 'Y (walking heart rate) = 143.346 - 2.63X (age)' ($R^2$=.3425), (p=.00). 4) The walking heart rate decreased as body surface area (BSA) increased. Linear regression equation between walking heart rate and BSA was 'Y (walking heart rate) = 149.830 - 27.115X (BSA)' ($R^2$=.3066), (p=.00). In conclusion, these equations and PCI could be useful to quantify the variation of energy expenditure of children with pathological gait when compared with age-matched healthy children.

We aim to develop the breast bolus by using a 3D printer to minimize the air-gap, and compare it to commercial bolus used for patients undergoing reconstruction in breast cancer. The bolus-shaped region of interests (ROIs) were contoured at the surface of the intensity-modulated radiation therapy (IMRT) thorax phantom with 5 mm thickness, after which the digital imaging and communications in mdicine (DICOM)-RT structure file was acquired. The intensity-modulated radiation therapy (Tomo-IMRT) and direct mode (Tomo-Direct) using the Tomotherapy were established. The 13 point doses were measured by optically stimulated luminescence (OSLD) dosimetry. The measurement data was analyzed to quantitatively evaluate the applicability of 3D bolus. The percentage change of mean measured dose between the commercial bolus and 3D-bolus was 2.3% and 0.7% for the Tomo-direct and Tomo-IMRT, respectively. For air-gap, range of the commercial bolus was from 0.8 cm to 1.5 cm at the periphery of the right breast. In contrast, the 3D-bolus have occurred the air-gap (i.e., 0 cm). The 3D-bolus for radiation therapy reduces the air-gap on irregular body surface that believed to help in accurate and precise radiation therapy due to better property of adhesion.

Of the total defects that have occurred recently in the Korean construction market, over 30% are caused by the construction of defective waterproofing, and the phenomenon of air pockets in the waterproofing layer, which is caused by the concrete vapor pressure, is known to be the primary cause of defective waterproofing. Accordingly, in this study the theory about the relationship between water pressure and temperature as well as the damp-proofing volume of concrete and, then, the change of vapor pressure volume was measured and analyzed by making a test sample after spraying a dampness remover and a waterproofing material to a prepared test body. As a result of measuring the water vapor pressure for the surface temperature of the waterproofing layer with the fluid-applied membrane temperature based on about $10^{\circ}C$, which is the average temperature of Seoul, it was found that first, the fluid-applied membrane elevated up to about $40^{\circ}C$, and the water vapor pressure generated from the fluid-applied membrane was about $0.3kgf/cm^2$ when the surface temperature of the waterproofing layer was raised up to about $80^{\circ}C$. Second, when the fluid-applied membrane temperature of the waterproofing layer was raised from $30^{\circ}C\;to\;35^{\circ}C,\;about\;0.1kgf/cm^2$ of water vapor pressure was generated, and when supplying a thermal source to raise the fluid-applied membrane temperature of the waterproofing layer from $35^{\circ}C\;to\;40^{\circ}C$, approximately $0.05kgf/cm^2$ of water vapor pressure was generated.

This study measured the effect 3D printing products comprised of different materials and shapes on heat transfer in clothing to derive fundamental data on thermal comfort among clothing comfort. The variables were three types of material (EVA foam, TPU-10%, TPU-10%+EVA), two types of shape (without holes, with holes), and two types of covers(without cover, with cover). All samples (12 types) prepared by combining these variables were placed on the hot plate set at 36℃, and the surface temperature was measured at three points for 10 minutes. The surface temperature change was dependent on the material, shape, and cover of the sample. The sample printed with TPU exhibited higher temperature transfer compared to the EVA foam sample after 10 mins. In addition, the temperature transfer was better when there were holes, and rate decreased when the sample was covered with fabric. We confirmed that material selection of the pad and thermal conductivity of the cover are extremely important in solving thermal stress to the human body caused by functional clothing with protectors. Additionally, as the protector, it is recommended to design the outer shell with a passage, such as a hole, to allow the rapid transfer of heat to the external environment.

Aging is characterized by an age-dependent reduction in bone density. Pronounced bone loss by postmenopausal estrogen deficiency induces a bad effect on dynamic balance of bone metabolism. When the bone density is reduced to the level below the fracture threshold, the risk for fracture is greatly increased. The purpose of this study is to examine what are the effects of the Guisinhwan(GSH : 歸腎丸) on the ovariectomized rat model of postmenopausal osteoporosis. The results of the experiment are as follows: Body weight in control group showed significant increase in comparison with sham, but that in GSH-treated showed no change in comparison with control. The level of serum albumin in control group showed significant decrease in comparison with sham. That in GSH-treated was slightly decreased in comparison with control. The level of serum ALP activity in control group showed significant increase in comparison with sham, but that in GSH-treated was significantly decreased in comparison with control. The level of serum phosphorous, calcium, GOT, GPT, T3 did not significant change among the three groups. The level of serum estrogen in control group showed slightly decreased in comparison with sham, but that in GSH-treated showed no change in comparison with control. The level of serum T4 in control group showed significant increase in comparison with sham, but that in GSH-treated was significantly decreased in comparison with control. Trabecular bone area as well as trabecular thickness in control group showed significant decrease In comparison with sham. Those in GSH-treated showed significant increase in comparison with control. Trabecular number did not significant change among the three groups. Trabecular separation only in GSH-treated showed significant decrease in comparison with control. Osteoclast number in control group showed significant increase in comparison with sham. That in GSH-treated showed significant decrease in comparison with control. Oseoblast surface in control group showed significant increase in comparison with sham, but that in GSH-treated showed no change in comparison with control. According to the above these results, GSH has shown to be capable of preventing and curing osteoporosis caused by old-aged and postmenopause.
