Vertical e-Marketplaces have been expanded because of their enough funds and purchasing power, while horizontal e-Marketplaces have not been grown. On the e-Marketplace which is dealing electronic components with the characteristics of short life cycle and diversities, if an e-Marketplace participant holds a large quantity of the same kinds of components, it will result in lowering competitiveness of the company because of its unuseful inventory. Therefore, as a method for increasing competitiveness of e-Marketplace participants, we proposed the inventory sharing method among the participants, and then designed and implemented it in this paper. For providing inventory sharing function, the e-Marketplace system needs intermediary because each system of participants participating e-Marketplace uses its own DBMS respectively. In this paper, we implemented inventory sharing function using XML, which is a standard for exchanging data, as intermediary, and showed an example of the implemented system.

The objective of this study is to offer a basic data for the establishment of marketing strategies such as fixing price of a new product and creation of the development direction of the product through estimating consumers value by attributes of the newly developed university made multi cream. The Choice Experiment was used for analysis, and conditional logit model was estimated to derive the marginal willingness to pay(MWTP) of each attributes of the multi cream. Brand, container type, functionality, price were included as the attributes. As a result, MWTP were estimated at 21,754 Won/unit for large company product, 11,033 Won/unit for small company product and 16,178 Won/unit for university product, 7,476 Won/unit for enriched moisturizing, 12,107 Won/unit for enriched improvements in wrinkles. Consumers have a preference for university brand over small company brand, therefore, if university and small company cooperate and proceed a joint-venture, it will strengthen the competitive power in the low price brand market. Also, it is essential to develop products with enriched functionalities such as moisturizing and improvements in wrinkles.

It is said that the highlight in the media covergence and integration within digital environment era is 'Contents'. Due to the advent of new media and various covergence and integration services, the competition between the platforms has become aggressive. As a result, it is predicted that the negotiation power of a 'Content's industry will be strengthened. In reality, the actual environmental changes in the media environment have accompanied elements of industrial crisis rather than opportunity to expand the market. The changes are especially causing sales structure distortion and proceeds deterioration in the Korean film industry. Moreover, telecommunication and broadcasting businesses are making their entrance into the film industry, through the appearance of the media covergence and integration as a backdrop. Thus, the situation that the Korean film industry is facing is closely associated with the development of the digital technology and new media environment. Eventually, weathering the crisis and pioneering the future will be possible through changes in the media environment. The purpose of this study is to show how the media covergence and integration phenomenon is occurring in the film industry. This study will also focus on what new problems are occurring as a result, and seek out the solutions that are available.

Recently as fine and ultra fine particles become major environmental issues in Korea, it is very important to develop effective solutions to air pollution. Accordingly this study aims at detecting causes of air pollution by using models and examining if diesel price increases contribute to reduction of diesel consumption and air pollution. TSP, PM10, $NO_X$, $SO_X$, CO, and VOC are included as major air pollutants. As a result, we found invert U shape curve between pollution and income for all air pollutants except CO. Consumer price index, coal power capacity, diesel consumption, frequency of yellow dust, number of natural gas buses, number of transport business, annual average temperature, number of manufacturing businesses are also influential in explaining causes of air pollution. As diesel price increases by 1%, air pollutants decline between 0.07~0.12% in the short run. Simultaneously, the additional revenue from increases in diesel prices might be transferred to support expansion of biofuel market. Also, stronger policy should be developed to mitigate the current air pollution problem.

This paper intends to examine the antecedents to the ex-post supply price cut which is typical retailer's unfair trade practices from three perspectives such as market power, efficiency, and retailer's tendency. For the empirical research, we analyzed manufacturer's 79 key account managers who have traded with domestic discount stores. As a result, the harder a retailer tries to increase sales and margin simultaneously, the more the retailer tends to use the ex-post supply price cut against manufacturers. In addition, the most frequent pattern of ex-post supply price cut occurs after retailer's discount at discretion. Finally, we suggest this research's implications, limitations of this research with future research directions.

The gasoline direct injection (GDI) system is considerably spreading in automotive market due to its advantages. Nevertheless, since GDI system emit higher particle matter (PM) due to its combustion characteristics, it is difficult to meet strengthened emission regulation in near future. For this reason, a combined GDI with MPI system, so-called, dual injection (DUI) system is being investigated as a supplemental measure for the GDI system. This paper focused on power and fuel consumption effect by injection mode strategy of DUI system in part load and idle engine operating condition. In this study, port fuel injectors are installed on 2.4 liters GDI production engine in order to realize DUI system. And, at each injection mode, DOE (design of experiment) method is used to optimize engine control parameters such as dual injection ratio, start of injection timing, end of injection timing, CAM position and so on. As a consequence, DUI mode shows slightly better or equivalent fuel efficiency compared to conventional GDI engine on 9 points fuel economy mode as well as MPI mode shows less fuel consumption than GDI mode during idle operation. Furthermore, DUI system shows improvement potential of maximum 2.0% fuel consumption and 1.1% performance compared to GDI system in WOT operating condition.

The major source of harmful air pollutants in Korea have been shifted as economy grows. Particulate matter(PM) and Sulfur dioxide ($SO_2$) emitted from industries and coal-fired domestic sectors were important pollutants in 1970's and later industrializing period of Korea. Then the characteristic of pollution was changed into so-called "developed country type pollution". Vehicles have been responsible for significant amount of Nitric oxide ($NO_x$) pollution and consequent Ozone formation in urban area since 1990's. Variety of control measures have been introduced to deal with the vehicle emissions in Seoul Metropolitan Area (SMA). Emission control technologies have successfully reduced pollutants from vehicles. Three-way catalyst for vehicles fueled by gasoline and liquefied petroleum gas (LPG), for example, has achieved large amount of pollutants. Compressed natural gas (CNG) urban bus have penetrated existing diesel bus market and reduces PM and $NO_x$ emissions in many Korean cities. However, diesel vehicles are still reaming as a critical emission source of urban area. Diesel vehicles gain more popularity than ever because of their better fuel efficiency and driving power. Unfortunately, it is widely known that the pollutant emissions of diesel vehicles are much larger than those of gasoline and LPG vehicles. In this note, we briefly introduce the trends of emission control strategies which are accomplished by automotive industries for about last ten years. Emission regulation, cleaner fuel, diesel particulate filter (DPF) and other measures are discussed from technical as well as legislative perspectives.
