Objectives : In this study, we tried to analyze the relationship between effect terms and five tastes in heat-clearing herbs. In order to analyze exactly, we also attempted to extract and refine the effect terms. And finally, we tried to infer the effects of each tastes and suppose new effects of each heat-clearing herbs based on their tastes. Methods : Firstly, we extracted the five tastes and effect terms among the heat-claearing herbs written in Herbology. After that, we divided each effect terms to single meaning term and refined them. We also grouped herbs by tastes and set the effect terms in the order of frequency. So we could analyze the relationship between the tastes and the effect terms and supposed the effect of each herbs. Results & Conclusions : We extracted 7 tastes and 87 effect terms. And they was refined to 63 effect terms. As the result of analyzing the effect terms based the tastes, all of heat-clearing herbs included the effects of heat-clearing and detoxification, regardless of tastes. The herbs which have the bitter tastes, included the effects of drying dampness, fire-purging and blood-cooling. And we supposed new effects in 10 kinds of herbs among them. The herbs which have the sweet tastes, included the effects of blood-cooling and fluid-engendering. The herbs which have the hot tastes, included the effects of inducing diuresis and swelling-dispersing. And we supposed new effects in 2 kinds of herbs, by analyzing the relationship between the tastes and effect terms.

Generally, polyester microfiber has much greater dye uptake than that of regular ones. In spite of high dye up-take visual shade depth of dyed fabric decreases with smaller denier, which results in poor washing fastness of dyed fabric. In this study, in order to investigate the washing fastness, polyester microfiber fabric was dyed by using two type of disperse dyes and treated with 3 different reduction clearing methods. The reduction clearing methods in this study are normal alkaline reduction clearing, $N_2$ gas replacement method, and ultrasonic treatment during reduction clearing. The results were as followings ; The most important factors affecting the washing fastness of polyester artificial suede fabric were found to be the reduction clearing method, the chemical structure of used disperse dyes and the structure and denier of fibers. It was also obtained that the heat treatment of dyed fabric decreased the washing fastness due to the dye migration from inner phase to surface.

Background and Objectives Although lasers have been widely applied in tissue treatment, the light penetration depth in tissues is limited by the tissue turbidity and affected by its absorption and scattering characteristics. This study investigated the effect of using an optical clearing agent (OCA) on tissue to improve the therapeutic effect of 1064 nm wavelength laser light by reducing the heat generated on the skin surface and increasing the penetration depth. Materials and Methods A diode laser (λ = 1064 nm) was applied to a porcine specimen with and without OCA to investigate the penetration depth of the laser light and temperature distribution. A numerical simulation using the finite element method was performed to investigate the temperature distribution of the specimen compared to ex-vivo experiments using a thermocouple and double-integrating sphere to measure the temperature profile and optical properties of the tissue, respectively. Results Simulation results showed a decrease in tissue surface temperature with increased penetration depth when the OCA was applied. Furthermore, both absorption and scattering coefficients decreased with the application of OCA. In ex-vivo experiments, temperatures decreased for the tissue surface and the fat layer with the OCA, but not for the muscle layer. Conclusion The use of an OCA may be helpful for reducing surface heat generation and enhance the light penetration depth in various near-infrared laser treatments.

Instead of fertilizing the lands they moved to find other fertile lands and lived a feudal life agriculture and various machincs played a main role in the land reclamation. The best method of land clearing, the time and capacity in the operation and the effect of growing crops should systematically analized prior to the time of 3rd Five-year Economic Development(1972-1976) in order to cultivate 210,000ha of wasteland or the modernization of our country. The present study was investigated to find out a new working-system of mechanical land clearing and development of fertile soil. The results are as follows: 1) The first stage of productive power increases when weeds were mixed soil in the land clearing work in order to supply organic materials and to make soil swollen instead of burning or just removing. 2) The equipments such as bulldozers, harrows, power tillers and so on should be prepared in order to do a systematic work in the land clearing. 3) The work of pulling-up roots is dependent upon the forms of roots spreading under the ground. The work of the pulling-up of the straight roots was most difficult. But before the roots are pulling-up we do not know the forms of roots. 4) The cutting of soil from upside to under side land clearing method (II) Spent 6 hr 7 min 43 sec per 1 Danbo in doing land clearing and control method spent 4 hr 52 min 30 sec per 1 Danbo in doing land cearing. No significant difference could be found between II treatment type and I treatment type. 5) The volume of soil carried by bulldozer $270.38m^3$ per 1 Danbo in I type and in II type, $368.58m^3$ per 1 Danbo or about 36% increased in II type then in I type. But that is not a significant difference when considering the whole productive power of soil. 6) The land clearing of terrace by bulldozers cannot escape making the embankment slope of about $45^{\circ}$, and 25.3% should be decreased in the area. It is recommended to make use of the embankment slope by planting grass for cows. 7) The time of retary tilling increased 2.3 times or 1 hr 42 min 22 sec per 1 Danbo compared to the timesrequired in the harrowing. Because it mixed the Organic matter on ground and the harrowing of subsoil. 8) The havest of pasture growing on the land reclamation in natural slope is as follows. (a) The none fertilizers with reclaimed block of productivity decresed 1/10 than that of the farmland. Therefore the none fer tilizing in the cultivated pasture is unprofitable. (b) The havest of the manured IV treatment block was the best not only in the kinds of fertilizers but also in the kinds of pasture grass.

옛날부터 우리들의 선조들이 한반도에 정착하면서부터 산야를 파서 농경지를 조성하였으며 지력(地力)을 회복하는 대신 토지를 교체하면서 오랫동안 봉건적 농업을 이루어 나왔다. 근대농업은 기계를 도입하였으며 따라서 농지조성도 기계개간을 하게 되었다. 종래와 같이 산지를 파면 된다는 피상적인 형식에 그칠 것이 아니라 실질적으로 개간작업방식, 작업시간, 작업능율, 작물재배효과 등을 종합하여 가장 우수한 방법을 추출(抽出) 연구하여 제3차 경제개발 5개년 계획기간 ($1972{\sim}1976$)에 21만정보의 농경지를 조성하므로서 조국의 근대화에 이바지하고져 기계개간의 새로운 작업체계와 숙지화촉진에 관한 연구를 하게되어 다음과 같은 사실들을 알게 되었다. (1) 토지경사도 $10^{\circ}$정도는 계단전개간보다 원지형개간을 하는 것이 개간작업이나 영농작업에 유리하다. (2) 개간작업에서 잡초를 태우거나 청소하지 않고 가급적 표토에 혼입함으로서 유기물을 공급하고 토양을 팽연하게 하였다. (3) 개간작업은 불도우저, 트랙터, 해로우 자동경운기, 로오타리 틸러등 여러 가지 장비를 갖추어야 일관성있는 작업을 할 수 있다. (4) 발근작업은 나무뿌리가 땅속에 뻗어있는 모양에 관계가 있는 것으로 직근계, 측근계, 사근계 중 직근계가 뽑기 어려웠다. (5) 주름잡이구(IV)의 개간작업이 발근과 첫갈이가 확실하며 쇠토작업도 간단히 처리되었다. (6) 운토량은 $240m^3/10a$로 표준구보다 15.6%정도 증가하였으나 개간작업시간은 2시15분45초/10a로 표준구의 1/3정도 걸렸다. 즉 2/3나 단축되었다. (7) 디스크 해로우잉(쇠토작업)은 기경지(旣耕地)쇠토작업에 비하여 작업시간이 50%증가하여 15분/10a 걸렸다. (8) 토오타리 틸링은 작업시간이 기경지에 비하여 2.4배나 증가하여 1시47분43초/10a이었다. 그 까닭은 심토(心土)의 쇠토작업이 어려웠기 때문이다. (9) 개간지는 토성에 맞추어 비료를 투입하여야 한다. 특히 퇴비는 1,200kg/10a. 석회는 20kg/10a 이상 투입할 것이다. 그리고 퇴비생산을 위하여 앞으로 채초지(採草地)가 필요하게 되었다. (10) 목초재배시험은 현재 재배중이어서 아직 그 결과를 알 수 없으나 개간효과와 숙지화정도가 밝혀질 것으로 기대된다.
