Because of the rapid growing traffic volumes of cargo, especially between Seoul and Inchon, and lack of investment into transport infrastructure in the past, in Kyong-in area have suffered from the serious traffic congestion in the public-road and the express-way network, But the further expansion of the traffic volume in near future is difficult due to burden of the higher expansion of the traffic volume in near future is difficult due to burden of the higher construction cost. Although the traffic congestion on the Kyung-in railway, is not very serious comparing with the road sector, the shortage of capacity on some main lines becomes emerged as a problem as railway traffic has increased. Unlike these two modes, the water transport, which has been paid relatively less attention for commodity transport in Kyong-in area, has not any constaint in this respect. Han river has been used as a water transport route in Chosun Dynasty which is called Cho-wun. This paper therefore aims to propose the availability of Han river as the alternative water transportation mode, in order to decrease the congestion between Seoul-Inchon by considering the construction of Kyong-in artificial water channel in near future. In this paper, we investigate the availability of Nanji-do as the physical distribution depot connecting with the circulation express way in the national capital distribution depot connecting with the circulation express way in the national capital. We also estimate the traffic volume by using the push-barge carrier (300DWT) in the same channel through the simulation under some assumptions such as ship's turnaround time, speed, etc.

본 연구는 농산물 직거래에서 큰 비중을 차지하는 농협 상설매장에 대한 소비자의 이용실태와 평가에 대해서 분석해 보고, 농협 상설매장의 활성화 방안을 모색해 보고자 하였다. 농협 상설매장을 이용하는 소비자 257명을 대상으로 설문조사를 실시한 결과 하나로마트는 근린 생식품 매장으로, 하나로클럽은 농산물 및 식품류 할인매장으로 고객들에게 인식되고 있었다. 전반적으로 도시의 소비자들은 거리가 가깝거나 농협이라는 이름이 주는 신뢰성 때문에 농협의 상설매장을 이용할 의사는 높은 편이었다. 농협 상설매장이 믿을 수 있는 농산물의 전문소매점으로서 확실히 자리잡을 수 있다면 경쟁력 있는 농산물 직거래의 경로가 될 수 있을 것이다. 그러나, 조사의 결과에서도 드러났듯이 다른 소매점에 비해 투자가 적고 전문인력이 부족하여 농협매장에 대한 고객만족도는 그리 높지는 않았다. 매장 속성별로 매장의 소프트웨어적인 면(예: 판매원의 친절, 영업시간, 점포의 명성 등)에서는 고객들이 만족하고 있지만 하드웨어적인 면(예: 주차, 편의/부대시설, 셔틀버스 등)에서는 상대적으로 고객만족도가 낮거나, 타 점포와의 비교 우위도가 낮은 것으로 나타났다. 농협에서 이왕 소매사업에 뛰어들었다면 농협 상설매장의 활성화를 위해 많은 노력이 필요할 것으로 보인다. 본 연구에서는 농협 상설매장 활성화를 위한 전략적 시사점과 개선방안을 제시하였고, 연구의 한계와 향후 연구방향을 끝으로 제시하였다.

Purpose - During the last two years, convenient stores (CS) are emerging as one of the most fast-growing retail trades in Korea. The goal of this work is to forecast and to analyze sales at CS using ARIMA-Intervention model (IM) and exponential smoothing method (ESM), together with sales at supermarkets in South Korea. Considering that two retail trades above are homogeneous and comparable in size and purchasing items on off-line distribution channel, individual behavior and characteristic can be detected and also relative superiority of future growth can be forecasted. In particular, the rapid growth of sales at CS is regarded as an everlasting external event, or step intervention, so that IM with season variation can be examined. At the same time, Winters ESM can be investigated as an alternative to seasonal ARIMA-IM, on the assumption that the underlying series shows exponentially decreasing weights over time. In case of sales at supermarkets, the marked intervention could not be found over the underlying periods, so that only Winters ESM is considered. Research Design, Data, and Methodology - The dataset of this research is obtained from Korean Statistical Information Service (1/2010~7/2016) and Survey of Service Trend of Korea Statistics Administration. This work is exploited time series analyses such as IM, ESM and model-fitting statistics by using TSPLOT, TSMODEL, EXSMOOTH, ARIMA and MODELFIT procedures in SPSS 23.0. Results - By applying seasonal ARIMA-Intervention model to sales at CS, the steep and persisting increase can be expected over the next one year. On the other hand, we expect the rate of sales growth of supermarkets to be lagging and tied up constantly in the next 2016 year. Conclusions - Based on 2017 one-year sales forecasts for CS and supermarkets, we can yield the useful information for the development of CS and also for all retail trades. Future study is needed to analyze sales of popular items individually such as tobacco, banana milk, soju and so on and to get segmented results. Furthermore, we can expand sales forecasts to other retail trades such as department stores, hypermarkets, non-store retailing, so that comprehensive diagnostics can be delivered in the future.

최근 관세청이 15개 수입소비재 품목 가격을 분석한 결과, 수입가격 대비 국내 판매가격은 2.1-4.8배 수준인 것으로 나타났다. 이는 아직도 독점 수입업체들이 폭리를 취하고 있다는 것을 보여주는 결과이다. 독점 수입업체가 아닌 제3자가 제품을 수입할 수 있는 병행수입은 1995년 이미 허용되었으나, 위조품 논란, A/S문제 등 때문에 실제 소비자 후생으로 이어지지 못했다. 정부가 최근 병행수입 활성화 정책을 펴면서 지난해 규모가 3조원으로 늘었으나, 아직 전체 소비재 수입의 5%에 불과하다. 관세청이 정식통관 제품이라는 것을 보증해주는 통관인증제 대상 업체와 품목 확대로 통관 인증업체가 344개로 늘어난 것은 매우 다행스런 결과이다. 이에 본 연구는 현재 국내 병행수입 시장의 실태와 문제점을 분석하고, 정부의 "독과점적 소비재 수입 개선방안"의 검토를 통해 향후 병행수입 제도가 국내 경제 활성화와 수입시장의 경쟁 제고를 위해 나아가야 할 방향을 제시하고자 한다.

Objectives : The object of this study is to evaluate and develop the system that reflects acupoints electrical properties by the multi-frequency using the SPAC (Single Power Alternative Current) stimulation method based on BIA (Bioelectrical impedance method). Methods : The 12 channel meridian impedance measurement system (MIMS) was designed, which sets multi-frequency with 10 steps (1~10kHz). To check acupoints electrical properties, impedance of acupoints were measured from 11 acupoints selected from the LU and ST meridians. Results : Regarding distribution of measurement values by multi-frequencies, we found the lowest response at 1kHz was in common. But frequency bands which represent the highest response at each acupoint were various. Measurement values of each acupoint by multi-frequencies were expressed similar distribution (P<0.05). Also we could check same frequency band which showed the highest response at left/right equal acupoints (P<0.05). Conclusions : Through change of acupoints electrical properties by multi-frequency stimulation, we checked oriental medical diagnostic possibilities by using this system. We would progress variable clinical trials with this system for oriental medical diagnosis.

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 particular, Olive Young succeeded in going into the black after making efforts for a long time by many persons. Drugstores could succeed in the business owing to many persons in the past as well as customers who liked drugstores. However, drugstores once lost ways and recorded poor business results. The three drugstores, that is to say, Olive Young, Watsons making efforts to go into the black and W-Store pursuing traditional drugstore shall compete each other and make effort to satisfy customers' desire. In that way, the three drugstores can be assured of present business as well as future business. The consumers' demand trend has become special at sub-division so that drugstores that can satisfy the demand can succeed in the business. Large businesses may be more interested in the 4th generation retail business to produce good income and to have bright future. Drugstore business and market are likely to expand and develop owing to large business' participation in drugstore business. Drugstores expanded shop at Seoul and Gyeonggi-do until middle of 2000. Drugstore business at station sphere in Seoul and Gyeonggi-do that have high ratio of temporary population has low customer loyalty to have limitation on continuous growth. Since 2009, drugstores have opened new shops at local towns: From the year of 2010, drugstores need to establish multiple shop strategy by accelerating business speed and to allow customers to drop in the shop anywhere in the nation and to enter consumers' life deeply, so that they can strengthen business base definitely. Drugstores need to have price competitiveness to have multiple shop opening strategy and to satisfy consumers and to supply high quality services that is future subject to solve. And, Olive Young and Watsons that are Korean style drugstore need to keep system in order and to strengthen substance as Korean style drugstore and to expand marketing, so that they can get business outcome within 5 years that was done 10 years before and they become the 4th generation retail business. The study had difficulties at collecting material from the three drugstore because of poor cooperation. And, the author had great difficulty at collecting statistical material that was made in disorder. Further effort is needed considering such problems.

홈쇼핑은 미래 유통의 꽃으로 불린다. 그중 TV홈쇼핑은 IT기술의 강국인 한국이 산업을 리더 해나가야 한다. 하지만 중소기업은 어렵다. 이는 방통위의 정책 실패에 기인한다고 본다. 이러한 정책실패를 보완하기 위해 국내 선행 연구와 해외 현황을 분석하고 정책에 반영 하고 자한다. 특히 해외 홈쇼핑 현황과 정책 사례를 통해 국내 사업을 전망하고 중소기업을 활성화 되기 위해서 정부 정책으로 보완해야할 사항은 무엇인지 분석하였고 정부가 적극적으로 반영 해야한다고 본다. 일반 PP의 경우 이미 등록제로 되었으며 홈쇼핑 채널도 등록제로 시장에게 맡겨야한다. 채널이 많아짐으로서 공급자인 중소기업은 보다 더 많은 기회를 얻어갈것이며 소비자 입장에서는 적정한 가격으로 상품가격이 안정될것이고 고품질과 다양한 품목을 홈쇼핑을 통해 얻어감으로서 소비자 후생을 증대시킬 수 있을 것이다. 만약 홈쇼핑을 등록제로 당장 하기 힘든 상황이라면 차선책으로 허가제를 더욱 강하게 만 들어 가야한다. 홈쇼핑은 3년마다 재승인 을 받아야 하기에 재승인 조건을 강화 한다면 일부의 문제를 해결 할 것이다.

전자부품생산 중·소 제조업체의 물적유통시스템의 효율성과 합리성을 향상시키기 위한 개선방안과 성력화, 정보화 내지 국제화 등의 기업환경변화에 대응해 물적유통을 전략적 측면의 「제3의 이윤원」으로 활용하도록 하는데 필요한 자료를 제공하기 위해서 2009년 6월부터 2009년 8월까지 약 3개월간의 기간을 거쳐 문헌조사방법과 설문지 조사방법을 병행하여 자료를 수집하였다. 연구조사 대상기업으로는 전자부품생산 제조업체 가운데 중·소기업을 중심으로 서울지역에서 27개사, 광주지역에서 10개사, 부산지역에서 12개사, 기타지역에서 10개사, 총 59개사를 선정하여 실태분석을 한 결과 물적유통시스템 구성요인의 효율성과 합리성을 향상시키기 위한 방안으로는 제품부문에서 고객과의 관계지향성을, 시장부문에서는 유통경로구조의 변경과 컨소시엄을 통한 자체 브랜드 개발 및 국내·외 시장에서의 판매계획을, 보관·창고부문의 경우에는 대기업과 연계할 수 있는 방안과 제3자 물류운영체계로의 전환 그리고 정부의 지원을, 수송부문에서는 철도수송의 활용과 「일괄수송협동체계」 내지 전국적인 「네트워크」망 구축 및 단위화물의 적정화를, 포장부문에서는 「유닛 로드 시스템」을 통한 포장규격화와 표준화 및 포장에 대한 전문업체의 교육프로그램 내지 포장기기에 대한 기술혁신이 선행되어야 하며, 재고부문의 경우에는 최고경영자 내지 담당자의 재고에 대한 새로운 접근인식을, 정보 및 컴퓨터 부문에서는 전산화의 정도가 유통 부분간에 상당한 차이가 있지만 궁극적으로 유통분야를 하나로 통합할 수 있는 「통합물류정보서비스(OSS:One-Stop-Service)」망의 구축을, 물류비구성부문에서는 「물류비 산정통일기준」의 제정 및 보급과 확립을, 마지막으로 물적유통시스템부문에서는 전문인력과 투자재원의 확보 및 아웃소싱의 활용을 들 수 있겠다. 결국 물적유통시스템의 합리적인 관리방안은 그 구성요인들의 체계화에 달려있다고 할 수 있으며 그 범위가 워낙 광대함으로 개별 경제적 입장에서 다루기보다는 사회경제적 관점하에서 전체적인 물적유통시스템을 체계화하는 방안으로 접근해야 할 것이다. 그리고 연구의 분석 틀을 가지고 전자부품 생산업체의 물적유통시스템을 개개의 요인으로 나누어 실태분석을 한 결과, 시사점으로는 ① 물적유통시스템의 구성요인이 통합물적유통 시스템으로 흐르지 않는 한 그 구성요인의 운영이 효율적으로 이루어지지 않을 것이다. ② 물적유통분야가 단순한 원가비용절감 분야가 아니라 기업의 중요한 전략적 의사결정분야로 그 중요성이 점차 증대될 것이다. ③ 물적유통 분야를 기업의 주요 경쟁전략 도구로 이용할 수 있다는 점을 들 수 있다. 그리고 연구의 한계점으로는 ① 실태조사를 통한 이론적 고찰에 그쳐 실증적 분석까지 이르지 못했다는 점, ② 임의표본추출에 의한 표본의 설정으로 그 결과에 대한 대표성에 상당한 문제가 있고 또한 결과에 대한 일반화에 제약이 있다는 점을 들 수 있을 것이다. 따라서 향후 이러한 한계점을 극복하기 위한 보다 체계적인 연구가 이루어져야 할 것이다.

WiMAX has been introduced as a competitive alternative for metropolitan broadband wireless access technologies. It is connection oriented and it can provide very high data rates, large service coverage, and flexible quality of services (QoS). Due to the large number of connections and flexible QoS supported by WiMAX, the uplink access in WiMAX networks is very challenging since the medium access control (MAC) protocol must efficiently manage the bandwidth and related channel allocations. In this paper, we propose and investigate a cost-effective WiMAX bandwidth management scheme, named the WiMAX partial sharing scheme (WPSS), in order to provide good QoS while achieving better bandwidth utilization and network throughput. The proposed bandwidth management scheme is compared with a simple but inefficient scheme, named the WiMAX complete sharing scheme (WCPS). A maximum entropy (ME) based analytical model (MEAM) is proposed for the performance evaluation of the two bandwidth management schemes. The reason for using MEAM for the performance evaluation is that MEAM can efficiently model a large-scale system in which the number of stations or connections is generally very high, while the traditional simulation and analytical (e.g., Markov models) approaches cannot perform well due to the high computation complexity. We model the bandwidth management scheme as a queuing network model (QNM) that consists of interacting multiclass queues for different service classes. Closed form expressions for the state and blocking probability distributions are derived for those schemes. Simulation results verify the MEAM numerical results and show that WPSS can significantly improve the network’s performance compared to WCPS.
