For the purpose of searching examination in the connection with clinical medicine and the basic theory of Korean Medicine, we comparatively studied on the physiological system of Hyun-Gok (1912~1987) and the Hyunsang system of Ji-San (1927~2000). The results are as follows. The metabolism of Yin and Yang is connected 'Gallbladder (膽)'-'Bladder (膀胱)' and Man (男), Woman (女), Old aged (老), Young child (小) style. Man and Woman are divided in the body form chacteristic not by the sex. 'Gallbladder (膽)'-'Bladder (膀胱)' style are divided in the body form chacteristic by the terms of Yin (陰) and Yang (陽). 'Gallbladder (膽)' style represents excessive Yang and deficient Yin, 'Bladder (膀胱)' style represents excessive Yin and deficient Yang. The four composition factor of the body is connected Material basis (精) type, Vital energy (氣) type, Mental faculties (神) type and Blood (血) type. In the diagnosis of body form on the Hyungsang Medicine, there are several types of body shape and categories of people. The Material basis (精) type, Vital energy (氣) type, Mental faculties (神) type and Blood (血) type are classified by the four composition factor of the body. The structural-mechanics organization of five Internal Organs (臟) is connected five Internal Organs (臟) types and the running-animal (走), bird (鳥), fish (魚), turtle (甲) types in the Hyunsang system. The five Internal Organs (臟) types are percived on the ears, eyes, nose, mouth and facial complexion. And the running-animal, bird, fish, turtle types are accorded to the individual personalities and the most-developed part in the body trunk by the Organ picture (藏象) theory. The six atmospheric influences (六氣) is connected the six Kyung types (六經形). The six Kyung types are regulated by the shape of eyes and nose representing for the relation of Vital energy (氣) and Blood (血). By the comparative study on the physiological system of Hyun-Gok and the Hyunsang system of Ji-San, we can search the connection with clinical medicine and the basic theory of Korean Medicine.

In this study, two types of water-soluble sulfur, LSA and LSB, were developed and the influence of the water-soluble sulfur on the mechanical properties and durability of concrete were experimentally evaluated. In order to evaluate mechanical properties and carbonation resistance of concrete with water-soluble sulfur, compressive strength test, flexural strength test, bonding strength test, and carbonation resistance test were performed. Compressive strength of only concrete with 1% LSA was increased while that of concrete with LSB was proportionally increased with the higher LSB dosage. On the other hand, flexural strength of concrete with LSA and LSB was increased by 12-41% and 36-74%, respectively. Carbonation resistance of concrete with water-soluble sulfur were increased by 25-66%. As a result, it should be noted that the water-soluble sulfur can not only solve the demerit of sulfur concrete but also offer the durability of sulfur concrete.

The aim of this study was to investigate the correlation among bone mineral density(BMD), body composition and body circumference on 20's college women in Hwaseong. A total of 86 subjects were measured with BMD and body composition and body circumference. To evaluate the correlation between BMD and body composition, bone density and body weight, body mass index(BMI), lean body mass, muscle mass, fat mass and body fat mass were compared. The results of this study, weight was considered the strong correlation with BMD than the height and BMI seems to be greater significance rather than the lumbar spine and femur BMD. In addition, the relationship between body composition and BMD, lean body mass, muscle mass, body fat mass were the most relevant factors and BMD. The relationship between BMD and body circumference that have been difficult because of not enough previous studies but somewhat the study showed that association.

Coffer dam for tunnel type spillway in inflow section of Dae-am dam was originally planned as 2 lines sheet piles with Water Zet method. But, the result of pilot test was caused of some problems that vibration during installation of pile could pollute water and water leakage could the lower part. So, sheet piles was not satisfactory for faculty of coffer dam. Structural instability of sheet pile system need to reinforcement. Characteristic of Dae-am dam was small reservoir capacity but wide drainage area, of which it was judgment that security of leakage and stability was difficult during excavation of inlet part. So, we consider that water curtain method utilized with in site pouring concrete pile method was designed at weir part of spillway. We were known about basement rock that geological boring was carried out in weir part. After taking a deep consideration, PRD method was accepted as a new method. Concrete pile by PRD was installed to below country rock. CJM method was carried out with PRD. After making concrete wall using Top-down method, earth anchors were installed for supporting it. According to the result of numerical analysis, as water level rises, wall is stable.

Objectives : Accumulation point is a useful acupoint for acute pain diseases. Among the eight extra meridians, only four (Yin Heel, Yang Heel, Yin Link, Yang Link vessel) have accumulation point and the others (Governor, Conception, Thoroughfare, Belt Vessel) do not. However, there is no explanation why these four meridians do not have it. So, the authors researched the literature to look for the reasons. Methods : We investigated 10 books and 1 paper about the 'accumulation point of extra meridians' using several search engines and researched reason why the other 4 meridian do not have it. Results : All of the 16 accumulation points are located on the 4 limbs. The four limbs have more Yang energy than the trunk. The governor, conception, thoroughfare, and belt vessels do not flow in the limbs. It seems that there is no acupoint located on deep gap enough to be the accumulation point among the four vessels. When it comes to the functions of these vessels, they are little related with the acute pain that is the main target of the accumulation point. Conclusions : From the results of this study, it seems to be reasonable that the four vessels do not have accumulation point.

Objectives : This study was performed to find the desirable remaining time of needle in the acupuncture treatment. Methods : The 21 volunteers were given acupuncture at LU9 vertically and needles were remained for 2 min, 10 min, 15 min, 30 min, respectively. The thermographic change induced by acupuncture was measured with Digital Infrared Thermographic Image at the following acupoints: LU11, LU10, LU9, LU8, LU5, LU1, and PC7. The statistical significance of thermographic change was evaluated using paired t-test and post hoc Wilcoxon test. Results : The most significant changes after acupuncture were produced when needles were remained for 10 min or 15 min. LU11, LU5, LU1, and PC7 were the point at which all of the remaining time produced significant change commonly. At LU11, the biggest change was produced when needle was remained for 15 min, while at LU5, LU1, and PC7, the biggest change was produced when needle was remained for 30 min, and the smallest change was produced when needle was remained for 10 min at all of acupoints of LU11, LU5, LU1, and PC7. The unbalance between left side and right was decreased the most largely in 15 min group. Conclusions : The results of this study suggest that the desirable remaining time of acupuncture needle might be 15 min.

본 연구는 열수 전처리에 따른 사료의 영양소 함량과 반추위내 발효특성의 변화를 알아보고자 수행되었다. 본 시험은 2(대조구 또는 열수 전처리)×2(건초; 톨페스큐 또는 사일리지; 옥수수)의 요인설계를 통해 실시하였다. 열수 전처리는 사료에 물을 20% w/v 수준하고, 멸균기를 이용하여 열처리를 20분간 실시하였다(121℃, 0.12 MPa). 제조된 시험사료는 in vitro 배양 시험을 통해 39℃에서 24시간 및 48시간동안 배양하였다. 연구결과, 열수 전처리 후 ADF의 함량은 조사료 종류에 구분없이 모두 유의적으로 증가하였다. In vitro 24시간 배양 후 total VFA는 조사료 종류에 관계 없이 열수 전처리 후에 함량이 유의적으로 낮았으며(p ≤ 0.05), Propionate 함량은 열수 전처리된 옥수수 사일리지에서 옥수수 사일리지 보다 유의적으로 증가하였다(18.9 vs. 26.6%; p ≤ 0.05). In vitro 48시간 배양 후에는 옥수수 사일리지에서 열수 천처리에 의해 propionate 함량이 유의적으로 증가하였으나(p ≤ 0.05), Butyrate 함량은 유의적으로 감소하였다(p ≤ 0.05). 건물과 NDF 소화율의 경우에는 조사료 종류에 관계없이 열수 전처리에 의한 변화가 없었다(p > 0.05). 따라서 열수 전처리된 옥수수 사일리지를 이용할 시 반추동물의 에너지원 공급에 유리할 것으로 판단된다.
