정연승,허정관 동중앙아시아경상학회 2011 한몽경상연구 Vol.22 No.1

갈수록 치열해지는 자동차 산업의 경쟁 속에서 자동차 기업들이 전통적으로 중요시해온 상품력외에 최근 자동차 유통에 대한 관심이 증대하고 있다. 자동차 유통매장은 신차 판매뿐만 아니라, 다양한 애프터세일즈 업무와 고객관리의 거점으로써 그 중요도가 점점 커지고 있다. 이에 본 연구의 목적은 첫째, 장기적인 관점에서 국내자동차의 지속 가능한 경쟁 우위를 담보 할 수있는 최적의 판매채널 구축과 바람직한 미래 유통시스템을 제안하고, 둘째, 국내자동차의 현실적인 경영자원과 제약조건을 고려하여 중장기적으로 적용 가능한 개선안을 도출함으로써 고객지향적인 유통구조로의 단계적 전환에 실무적으로 유용하게 활용될 기초자료를 제공하고자 한다. 본 연구는 이상과 같은 시각에서, 국내와 해외 선진국 자동차 유통시장의 특징, 국내자동차의 직영 및 대리점 판매망의 문제점 등을 구체적으로 고찰하였다. 국내자동차 유통시장과 미일 자동차 유통시장을 비교 분석한 결과, 다음과 같은 5가지의 전략적 대안을 제안하고자 한다. 첫째, 기존 직영판매망과 대리점의 장점을 극대화함으로써, 환경변화에 유연하게 대응해야 한다. 둘째, 새로운 운영방식으로 독립채산제의 도입을 검토할 필요가 있다. 셋째, 해외 유통망과 비교하여 다기능 복합거점 형태로의 전환이 필요하다. 넷째, 고객의 방문을 유도(Pulling)하는 점두판매형 거점으로의 전환이 필요하다. 다섯째, 고급 차종을 위한 고급채널의 별도 운영이다. In the face of stiff competition among automobile industries, automobile companies have been recently interested in automobile distribution rather than the commodities that were regarded as important traditionally. Automobile retailing store becomes more and more crucial not only in the sales of new cars but also in the base for a variety of after-sales business and customer management. The followings are the purpose of this study on the development strategy of domestic automobiles retailing system. First of all, We recommend that the companies should establish the optimal sales channels and desirable Retailing system to guarantee the sustainable competitive advantage of domestic automobiles in the global market from a long-term perspective. Second, taking actual business resources and constraints into consideration, I hope to provide the basic materials to make practical application of change of distribution system toward the customer as companies have to come up with feasible improvement scheme. Therefore, We considered the characteristics of domestic and foreign automobile market, and the problem of operating dual channels such as direct management and agencies in domestic market in all its aspects. From the result of this comparison, five strategic alternatives for domestic automobile makers can be suggested as follow. First, the company should take flexible actions against the change of environment by maximizing the strength of its existing direct-sellers and sale's agencies. Second, the company needs to consider initiating a self-supporting system as a new way of operation. Third, the company should be equipped with multi-complex distribution network to compete with overseas' companies. Fourth, the selling spot needs to move toward over-the-counter dealing spot which pulls the customer. And the last thing is opening a separate distribution channel devoted only for luxury-cars.

The acoustic emission (AE) sensor has been widely used for monitoring the machining states or tool abrasion, etc. This paper presents the relation between machining time and states such as tool abrasion for ceramic machining processes, which can be applicable to develop the dentistry machining center. A commercial PZT-type of AE sensor was used for experiments, and the aquisition data was analyzed in the AE signal strength versus machining time. The results show that it is possible to estimate the tool life and the ceramic machining state. In the future, additional experiments for various machining conditions such as depth of cut and feed rate are strongly necessary so as to design an effective monitoring system for the ceramic machining processes through detecting the AE signal.

Steering pull refers to vehicle’s drifting to the lateral direction without a driver’s steering input while on the straight driving. This study proposes a method to analysis effect analysis of the steering pull design parameter through the simulation of multi-body-dynamic vehicle model. Purpose of Effect analysis is to analyze the relationship of steering pull design variables. The design variables are hard point in front, rear suspension and force elements, tire property, road bank angle. Before conducting effect analysis, a vehicle model based on MBD(Multi-Body Dynamics) was made through reverse engineering, and it was verified by field test. As the design of experiment for effect analysis, a Placket-burman method was used. As a result of conducting an effect analysis of the steering pull factors, it was identified that the suspension hard point, bush property, road bank angle, tire and spring have an influence of 43%, 19%, 17%, 12% and 9%, respectively.

The digestive tract of the spotted sea bass, Lateolabrax sp. composed of esophagus, stomach, intestine and seventeen or eighteen pyloric caeca. The relative length of gut (RLG), that is length of digestive tract to standard length, is 0.79 (n=10). Esophagus have a undeveloped submucosa and well developed muscularis mucosae. In the stomach, muscularis consists of longitudinal and circular muscle layer, and submucosa and muscularis mucosae are well developed. In the body stomach, microvilli are observed in the epithelial layer. Mucosal epithelium of the pyloric caeca and intestine composed of columnar epithelium with developed microvilli in the apical portion. Intestine have a advanced striated border and more abundant goblet cells than the pyloric caeca. Intestine is divided into the anterior, mid and posterior part by the external and histological features. The anterior intestine have a more abundant goblet cells than the other part of the intestine. The mid intestine have a advanced submucosa and more abundant absorptive cells than the other part of the intestine. And the posterior intestine have a advanced mucosal folds and muscularis.

최근 지표환경변화과정에서 발생하는 복잡계적 특성에 대한 관심이 증가하고 있으며, 이러한 문제를 해결하기 위한 도구로 다행위자시스템에 대한 연구가 활발하게 이루어지고 있다. 이 연구는 최근 한국의 산림정책에서 중요하게 다루어지고 있는 산림개방의 문제를 사례로 토지피복변화의 직간접적인 영향을 평가할 수 있는 다행위자시스템(Multi-Agent System)을 개발하여, 강원도 평창과 정선의 가리왕산과 그 주변지역에 적용하였다. 이 연구에서 사용한 다행위자시스템은 LUDAS(Land Use DynAmic Simulator)로 인문환경과 자연환경의 공간적인 이질성과 상호작용을 동적으로 구현하는 강점이 있으며, 산지개방에 따른 사회·경제 및 자연환경적 영향을 종합적으로 비교·평가할 수 있는 장점을 가지고 있다. 모형은 인간 행위자와 그 의사결정으로 이루어져 있는 인문환경시스템, 자연환경과 산림생태계를 대표하는 자연환경시스템, 이를 연결하는 상호작용 연결고리와 정책 시나리오로 구성하였다. 모의 결과는 산림정책의 결과로서 지역주민의 소득과 생태계서비스의 가치, 소득 불평등의 정도로 도출하였다. 그 결과 최적의 산림정책 시나리오는 지형을 고려하여 산지를 개방하고, 지역주민을 대상으로 개방하며, 휴양지 목적의 산지 개방으로 도출되었다. 이 연구는 산림정책 수립과 토지이용 관련 정책연구를 위한 의사결정시스템 개발에 중요한 기여를 할 수 있을 것으로 기대된다. This paper presents a multi-agent system model of land-use and cover changes, which is developed and applied to the Gariwang-san and its vicinity, located in Pyeongchang and Jeongseon-gun, Gangwon province, Korea. The Land Use Dynamics Simulator (LUDAS) framework of this study is well suited for representing the spatial heterogeneity and dynamic interactions between human and natural environment, and capturing the impacts of forest-opening policy interventions to future socio-economic and natural environment changes. The model consists of four components: (1) a system of human population, (2) a system of landscape environment, (3) decision-making procedures integrating human(or household), environmental and policy information into forest land-use decisions, and (4) a set of policy scenarios that are related to the forest-opening. e results of model simulation by dierent combination of various forest management scenarios are assessed by the levels of household income, ecosystem service value and income inequality in the study region. As a result, the optimal scenario of forest-opening policies in the study region is to open the forest to local residential community for the purpose of recreation, considering the distinctive topographical feature. The model developed in this research is expected to contribute to a decision support system for sustainable forest management and various land-use policies in Korea.
