The retail business of drugstore was introduced to Korea for the first time 10 years ago. Since Olive Young introduced a retail store in the name of drugstore in 1999 for the first time in Korea, new distribution channel combining drugstore, cosmetic products and dairy products, etc has been made. At initial stage, the new distribution channel grew up slowly because of low specialty and economic stagnation. However, the three big distribution channels, that is to say, Olive Young (CJ), Watsons (GS) and W Store (Kolon Well Care), etc, were established to produce new distribution system following large-scaled discount stores as well as convenience stores. The purpose of the study is to investigate ways making Korean style drugstore be new retail business in addition to traditional markets, department stores, E-Mart and other general super markets and to examine problems preventing the drugstore from being promoted and to find out solutions. The speciality retailers that is called a category killer attacking department stores as well as marts is expanding market quickly. New consumption trend that gives priority to wellbeing is being expanded in accordance with high level of standards of living life: The drugstore is thought to be new alternative of distribution because it keeps special products. Young ladies who are main customers of drugstores respond to the trend sensitively to have more buying power that is thought to be promising. And, consumers' desire has become concrete and special. This is because consumers want not only convenient shopping but also special shopping system that is current trend. These days, so called Multi-shop and Total shop and other special shops have been recently opened. Special multi-shop has been concentrated on fashion product and miscellaneous goods so far: Health total wellbeing shop shall be popular in accordance with wellbeing trends. Drugstores can play an important role. Drugstores were opened for the first time ten years ago. In

Aerosol formation and growth by water vapor reactions were investigated in a 2.5-㎥ indoor smog chamber filled with the unfiltered ambient air. The relative humidity of test ambient air was elevated at 59~64% or 84~88% by adding water vapor. The aerosol number size distribution and the concentrations of O₃, NO, NO₂, and SO₂ were measured during the experiments. The O₃, and NO₂ gases were well reacted with the water vapor at high relative humidity of 84~88%, and the reaction rates of these gases seemed to be decreased at low relative humidity of 59~64%. The formation and condensational growth phenomena of ambient aerosols by water vapor reactions were observed in a Teflon bag, depending strongly on the initial particle size distribution. The water vapor reactions might be affected by the contents of oxidants produced by photochemical reactions under sunlight.

ABSTRACT - This study was performed to evaluate hepatoprotective effect of daewhang-whangryunhaedok-Tang(DWT) on liver injured rats induced by CCI_4 and the acute oral toxicity of it in mice. The activities of serum transaminase(ALT/AST), alkaline phosphatase(ALP) and lactic dehydrogenase(LDH), the levels of serum total cholesterol(TC) and triglyceride(TG), change of liver enlargement, and inhibitory activities of lipid perotidation, catalase and glutathione-S-transfrease(GST) in liver microsome were determined in hepatotoxic rats induced by CCI_4. DWT was significantly reduced the serum ALT, AST, ALP, LDH. TC and TG lecels. And, the increase of lipid peroxidation, decrease of catalase and GST activities in the liver microsome of CCI_4-intoxicated rat were significantly improved by the treatment of DWT. Male and female mice were administered maximum dosages of 5.000 mg/kg b.w. of DWT. After single oral administration of DWT to mice, we observed them daily for 2 weeks.DWT did not induce any toxic signs in the mortalitie, clinical signs, body weight changes, and gross necropsy finfings of mice. Based in these results. It is concluded that DWT may have the hepatoprotective effect on CCI_4 induced hepatotoxicity in rats. Also. DWT may have no side effect and its LD_50 value may be over 5.000mg/kg b.w. in mice.

Whangryunhaedok-Tang (WT) is formulated with Coptidis Rhizoma, Phellodendri Cortex, Scutellariae Radix and Gardeniae Fructus, and Daewhang-whangryunhaedok-Tang (DWT) is made by the combination of Rhei Rhizoma, a wellknown anticostipation drug in WT. Therefore, DWT has been evaluated for antihyperlipidemic effects on experimental hyperlipidemic rats and mice induced by corn oil and high cholesterol-diet. Oral administration of DWT significantly inhibited the increase of serum triglyceride and LDL-cholesterol levels, and the decrease of serum HDL-cholesterol levels in hyperlipidemic rats induced by corn oil. Also, oral administration of DWT significantly prevented the increase of serum total cholesterol, triglyceride and LDL-cholesterol, and liver total cholesterol and triglyceride in 1% cholesterol-diet fed mice. These results suggest that DWT is effective for the treatment of hyperlipidemia.

본 연구는 고콜레스테롤 식이 군에 제주산 해조 식이섬유의 첨가 수준을 달리한 식이가 흰쥐의 지방대사에 미치는 영향을 알아보고자 하였다. 체중이 132.3±7.34 g인 Sparague-Dawley종 수컷 흰쥐에게 고콜레스테롤혈증을 유발시키기 위하여 콜레스테롤를 식이 사료의 0.5%가 되도록 첨가하고 제주산 해조 식이섬유 분말은 식이 사료의 각각 1.0% 및 2.5%가 되도록 첨가하여 총 3군으로 나누어 4주간 사육하였다. 체중 증가량과 식이효율은 식이에 의한 영향은 없었다. 혈중 중성지방, 총콜레스테롤, LDL-콜레스테롤은 고콜레스테롤 식이에 비해 제주산 해조 식이섬유를 첨가한 군이 크게 감소하였으며 유의적 차이를 나타냈다. HDL-콜레스테롤은 고콜레스테롤 식이 쥐에 비해 제주산 해조 식이섬유를 첨가한 군이 증가하는 경향을 보였으나 유의적인 차이를 보이지 않았다. 총 콜레스테롤 함량에 대한 HDL-를레스테롤 함량의 비는 제주산 해조 식이섬유를 첨가하였을 때 유의적인 차이를 보이며 증가하였다. GPT, GOT활성의 경우 GPT활성은 군간에 비슷한 경향을 보였으며, GOT활성은 제주산 해조 식이섬유를 첨가한 군이 유의적인 차이를 보이며 감소하였다. 항산화효소인 SOD 및 catalase 활성은 식이에 의한 영향은 없었다. 이상의 결과를 볼 때 제주산 해조 식이섬유의 체내 지방대사에 있어 총 콜레스테롤과 LDL-콜레스테롤, 중성지방 및 GOT 활성을 낮추고 HDL-콜레스테롤/총 콜레스테롤 비는 높이는 효과를 나타냈다. 따라서 제주산 해조 식이섬유는 생체내 항고클레스테롤 및 고콜레스테롤에 의한 스트레스로부터 간을 보호하는 것을 알 수 있었다. This study was conducted to investigate hypocholesterolemia effect of dietary fiber from seaweed in Jeju in rats supplemented with hish cholesterol diet. Seaweed dietary fiber was produced by water extraction of the mixed main red algae including Gracilaria verrucosa, Gelidium amansii, Gigartina tenella, Gloiopeltis furcata and Campylaephora hypnaeoides. Thirty male Sprague Dawley rats weighing 132.3±7.34 were divide into high cholesterol diet and high cholesterol diet plus seaweed dietary fiber 1.0% or 2.5% for 4 weeks. Dietary fiber supplement could significantly decreased serum total cholesterol (TC), triacylglyceride (TG), LDL-cholesterol (LDL-C) and GOT than in high cholesterol diet. HDL-cholesterol level and HDL-cholesterol/total cholesterol ratio in the two groups of seaweed dietary fiber supplement significantly increased comparing to those in high cholesterol diet without dietary fiber. These results suggest that the seaweed dietary fiber may reduce elevated levels of serum cholesterol concentrations.

Centrifuge model tests were performed to find appropriate equations proposed previously of estimating the bearing capacity of the composite clayey soil reinforced with sand compaction pile. Model tests were carried out with changing the replacement ratio of SCP (20%, 40%, 70%), contents of fine materials (5%, 10%, 15%) and ratio of treated width to loading width (1B, 2B, 3B). Test results about bearing capacity of the composite ground were obtained by performing the surcharge load tests with measurements of applied loads and vertical displacement. Bearing capacities against bulging and shear failures were estimated by the existing equations. As results of comparing the estimated bearing capacity with experimental values the bearing capacities estimated by Greenwood's equation (1970) for bulging failure mode were similar to the test results.

본 연구의 목적은 잠제나 기타 구조물에 비해서 파랑제어의 효과는 다소 적지만 트렌치의 설치로 인한 트렌치 전면에서의 반사율을 2차원 수리모형 실험을 통하여 규명하는데 있다. 방파제, 이안제, 돌제 그리고 잠제 등의 구조물에 대한 기존의 방사율 연구에 관한 자료는 많이 있으나 트렌치에 관한 연구는 거의 없는 상태이다. 트렌치를 설치함으로써 해수의 순환, 시공비 절감과 시공의 용이성, 이용수역의 확대, 그리고 준설후의 토양을 해안에 양빈함으로서 토사의 재이용 등의 효과를 기대할 수 있다. 실험방법과 해석은 Goda에 의해서 제시된 2점 관측법을 사용하였으며, 반사율의 변화를 규명하기 위해서 파랑과 트렌치 단면의 제반조건의 변화에 따라 파형경사, 상대수심, 상대파고에 따라 반사율을 비교 검토하였다. 그 결과 트렌치를 설치하였을 경우가 반사율이 크게 나타났고, 반사율의 전반적인 범위는 0.4∼0.7정도의 값을 나타내었다. The purpose of this study is to estimate reflectivity of trench and compare with the others by 2-dimension fixed hydraulic experiment in front of it though it is less effect than submerged breakwater of other structures in the wave control. There are many sources for reflectivity of structures such as breakwater, groin, jetty, and submerged breakwater except trench which is dredged channel. Trench, if constructed, will have more effect of seawater circulation, reduction in coast, ease in construction, expansion of water area, and sand recycling than the others. 2-point measurement which was suggested by Goda was used to analyze reflectivity and the ratios of wave reflection are compared for the wave steepness, relative depth, relative wave height. The result of this study shows higher reflectivity when trench constructed and the range of wave reflection was from 0.4 to 0.7.

A probabilistic analysis model, one of reliability analysis methods introducing the concept of probabilistic variables, was developed to investigate the uncertainty of dominant factors influencing the degree of consolidation in the radial consolidation theories. Based on the developed probabilistic analysis model, sensitivity study of those factors was performed to find their trends of affecting the degree of consolidation in the vertical drain method. Various radial consolidation theories, Proposed by Barron(1948), Hansbo(1979), Yoshikuni(1979) and 0noue(1988), were used for this parametric study with the influencing factors such as size of smear zone, reduction ratio of permeability in the smear zone, discharge capacity, permeability for horizontal flow and coefficient of consolidation for horizontal flow. As results of this sensitivity study, for the given consolidation theory, contribution of each factor to the degree of consolidation was figure out and compared to each other. For the given value of each factor, the sensitivity to the degree of consolidation in the various theories was evaluated and their applicability and limitations were assessed.
