The purpose of this study is to clarify of the distribution routes of cosmetics by their types and differences in choosing them according to ages with the ones in choosing brand by the type according to them. The subjects of the study were females aged 20 plus living in Seoul and Gyeonggi Province between January and February 2008, and 427 questionnaires were used for analysis. For data analysis SPSS 17.0 statistical program was used, and principal component analysis, frequency analysis, ${\chi}^2-test$, ANOVA test and Duncan test were conducted. The results and conclusions of this study are as follows: first, cosmetics store use by product type was examined. Department stores were used most often to purchase skincare, base and color products, while large cosmetics stores were used most frequently to buy hair and body products. Second, The result of the differences in choosing brand by type of cosmetics has found that there are the meaningful differences between Korean low and middle priced brands and foreign high priced ones in skincare and base products. The Korean low and middle priced brands of skin care products show that various distribution routes are simultaneously and highly used as choices in internet, cosmetics specialty stores and large general ones are higher than other distribution routes. Color products have found that there are the meaningful differences in the entire brands. Hair and body products have found that there are the meaningful differences in three brands except the Korean high priced brands. Third, the differences in cosmetics store selection by age were investigated. As for online purchasing, people in their 20's were most likely than other age groups to purchase online. Meanwhile, in case of other stores including door-to-door sales and home shopping, people aged 40 and older were more prone than other age groups to purchase base, color and body products through these stores.

The Inchon port has been heavily congested due to the tidal restriction in passing the lock and the shortage of berths or warehouses. The current congestion is predicted to become worse by the induced traffics near the lock entrance after completion of North harbour expansion and of Kyung-In canal construction. It is also expected that the newly developed configuration of the Inchon port will result in increasing the rate of marine accidents around the lock entrance because of the over-utilization of the limited capacity of the junction from the North harbour and the Kyung-In canal. This study adopts a systematic approach in analysing the physical distribution system of the inner-lock area in order to figure out alternative routes which are designed to improve the port efficiency. Ship maneuvering simulation is also attempted to propose a new approaching route to the canal as an alternative path in order to avoid the traffic accidents caused by the extreme congestion. The result of the ship maneuvering simulation demonstrates that the alternative routes by way of Buk-Sudo, Janbong-Sudo, north of Si-Do and Sin-Do is recommended routes which can satisfy the safety requirements of approaching to the canal entrance.

Purpose: Establishing a competitive advantage in the aviation market is essential as the competition among domestic airlines intensifies. Therefore, this study examined the management strategies of both large domestic airlines and low-cost airlines. Research design, data, and methodology: This study classified domestic airlines into Full Service Airlines (FSA) and Low Cost Carriers (LCC), examined each airline's current status and characteristics, and conducted case analyses of FSA and LCC based on Porter's generic competitive strategy. Results: The analyses determined that LCC primarily implemented a cost-advantage strategy, and FSA implemented a differentiation strategy. However, as competition intensified, FSA pursued cost-advantage strategies while establishing LCC through subsidiaries. There are various specific cost reduction methods, including service simplicity, scalability, high utilization, low landing fees, low-cost unit, and point-to-point flight strategies. Conclusions: LCCs are focusing on cost advantage strategies that reduce costs; however, the FSA also runs special price events that are as good as LCCs and are comparable to LCCs on some routes. Furthermore, LCC has recently expanded its mid- and long-distance routes, making competition for long-distance routes with major airlines unavoidable.

In this study, the initial in vivo pharmacokinetic changes according to the routes of drug administration were investigated using bioimaging techniques. The purpose of this study was to quantify the degree of distribution of each major organ in normal mice over time by acquiring Positron Emission Tomography/Computed Tomography images while administering routes F-18 fluorodeoxyglucose such as intravenous, intraperitoneal and per oral, a representative diagnostic radiopharmaceutical. Dynamic Positron Emission Tomography images were acquired for 90 minutes after drug administration. Radioactivity uptake was calculated for major organs using the PMOD program. In the case of intravenous administration, it was confirmed that it spread quickly and evenly to major organs. Compared to intravenous administration, intraperitoneal administration was about three times more absorbed and distributed in the liver and intestine, and it was showed that the amount excreted through the bladder was more than twice. In the case of oral administration, most stayed in the stomach, and it was showed that it spread slowly throughout the body. In comparison with intravenous administration, it was presented that the distribution of kidneys was more than 9 times and the distribution of bladder was 66% lower. Since there is a difference in the initial in vivo distribution and excretion of each administration method, we confirmed that the determination of the administration route is important for in vivo imaging evaluation of new drug candidates.

Many theories and researches about agricultural products transportation were proposed and introduced until now. These studies have insufficient consideration about factors like region of imported agricultural products and the different speed of each road. In this study the Optimal Routes Selection Model (ORSEM) included factors that aren't taken into account in past studies and consists of database using Internet. Finally the model was developed through advanced marketing potential function and optimization method. The ORSEM focalizes on transport network organization. This model was applied to physical distribution of agricultural products in South Korea and found optimum routes of agricultural products.

Half channel angular extrusion(HCAE) is the integration of equal channel angular extrusion(ECAE), which is a well-known severe plastic deformation(SPD) method, with conventional forward extrusion in order to increase the strain per pass and effectiveness of the grain refinement. In the current study, the effects of processing routes during HCAE(Routes A, B, and C) on the strain distribution of the specimens have been investigated for an AZ61 Mg alloy by using three-dimensional finite element analysis. Comparisons with the results from a multi-pass of ECAE are made.

항로는 선박의 통항이 빈번하여 사고의 위험이 높은 지역이지만, 선박의 통항분포에만 초점을 맞춘 연구가 다수였으며, 항로의 특성과 선박의 크기별 통항패턴에 대한 연구는 부족하였다. 이에 본 연구에서는 3개의 주요 항로에서의 통항분포와 통항패턴을 분석하기 위해서 3일간의 선박의 통항현황을 조사하였다. 통항현황을 바탕으로 항로를 10개의 Gate line으로 구분하고 각 Gate line을 통과하는 선박크기를 소형선, 중형선, 대형선으로 세 분류하여 분석하였다. 각 항로의 통항분석을 바탕으로 각 Gate line에서의 통항분포에 대하여 ND-K-S(Normal Distribution-Kurtosis-Skewness)를 적용하여 평가하였다. ND 평가 결과 통항분포에서 대형선은 정규분포를, 중형선은 편도항로에서만 정규분포를 만족하고, 소형선은 정규분포를 만족하지 않는 것으로 평가되었다. K-S 평가 결과 통항패턴은 왕복항로와 편도항로에서 뚜렷한 구분을 보였다. K 평가의 결과 편도항로에서는 고루 항로를 이용하는 통항패턴을 가지지만, 왕복항로에서는 항로의 한 부분에 집중하는 통항패턴을 가지는 것으로 평가되고, S 평가의 결과 편도항로에서는 항로의 중앙을 따라 항행하는 통항패턴을 가지지만, 왕복항로에서는 항로의 우측에 치우치는 통항패턴을 가지는 것으로 평가되었다. 다만 본 연구는 3개의 주요 항로를 비교한 만큼 향후 다양한 환경에서의 항로분석이 필요할 것으로 판단된다.

This paper aims to determining the optimal capacity of Pusan port in view point of Container Physical Distribution cost. It has been established a coast model of the container physical distribution system in Pusan port is composed of 4 sub-systems and in-land transport system. Cargo handling system, transfer & storage system and in-land transport system, and analyzed the cost model of the system. From this analysis, we found that the system had 7 routes including in-land transport by rail or road and coastal transport by feeder ship between Pusan port and cargo owner's door. Though railway transport cost was relatively cheap, but, it was limited to choose railway transport routes due to the introducing of transport cargo allocation practice caused by shortage of railway transport capacity. The physical distribution ost for total import & export container through Pusan port was composed of 4.47% in port entring cost, 12.98% in cargo handling cost, 7.44% in transfer & storage cost and 75.11% in in-land transport cost. Investigation in case of BCTOC verified the results as follows. 1) The optimal level of one time cargo handling was verified 236VAN (377TEU) and annual optimal handling capacity was calculated in 516, 840VAN(826, 944TEU) where berth occupancy is $\rho$=0.6 when regardless of port congestion cost, 2) The optimal level of one time cargo handling was verified 252VAN (403TEU) and annual optimal handling capacity was calculated in 502, 110VAN (803, 376TEU) where berth occupancy is $\rho$=0.58 when considering of port congestion cost.

We examined the evolutionary and ecological processes shaping current geographical distributions of a Korean wood-eating cockroach species, Cryptocercus kyebangensis. Our research aims were to understand evolutionary pattern of DNA sequences, to construct genetic network of Cryptocercus kyebangensis local populations and to understand evolutionary and ecological processes shaping their current geographical distribution patterns via DNA sequence information and genetic networks, using sequence data of two genes (ITS-2 and AT region) from local populations of C. kyebangensis. The results suggest that the ITS-2 and AT region are appropriate molecular markers for elucidating C. kyebangensis geographic patterns at the population level. The MSN-A based on the ITS-2 showed two possible routes, the Hwaak-san and Myeongji-san route and the Seorak-san and Gyebang-san route, for migration of ancestral C. kyebangensis into South Korea. The MSNs (MSN-A and -B) elucidate migration routes well within South Korea, especially the route of Group I and Group II.

Major companies have launched into the film industry since 1990s, which resulted in competition in facilities. In addition, restriction for the number of the prints was removed. Under these circumstances, the cinema has been transformed and developed from the established one-hall cinema into multiplex cinema with large-scaled halls. Contrary to the established cinema, modern cinema are a cultural place within easy access. They accommodate diverse social and cultural needs and their functions have been extending gradually. The waiting areas should not function only as the waiting space for the audience but also the places to attract the audience and provide them with various cultural and art information, and temporary restful break. For this study, the inter-relationship between the structure of the area and the audience are identified objectively by analyzing audience distribution and their routes within the area. The purpose of the study is to provide basic data about the design of the waiting area based on the findings above.
