This study aims to explore the ways of reinforcing the competitive edge and substance of company through e-business in furniture industry by presenting the e-business model of furniture industry which faces the opportunity of challenge in the course of industrial restructuring. e-business model can take various types depending on the environment, feature and competitive edge that each company faces. For example, it is general in the fields of manufacturing company to study the model by dividing into Sell Side for sales to the customers, and Buy Side for purchase of raw materials, Integrating both sides. In furniture industry, Sell Side has the feature of giving a priority in the quality and price rather than brand image in the purchase type of consumer. Especially, it shall not be overlooked that majority of furniture is delivered to the consumer indirectly through the construction company. As such, e-business should be promoted in a way to expand the point of contact for consumers, rather than to construct its own point of contact for consumers. The percentage of importation of raw lumber is high and the standardization was insufficient in Buy Side.

This study was undertaken to investigate the knowledge and the use of Korean traditional basic side dishes, dried side dishes and Jabans, by housewives. Among the 59 kinds dried side dishes and Jabans, the most well-known food (above 90% of subjects) turned out to be squid Po (dried strip), kong Jaban (seasoned bean), pollack Po, dried yellow croacker, build -dried anchovy Jaban and laver Boogag in the order. In cooking experience of dried side dish and Jaban, over 40% of subjects for build-dried anchovy Jaban, squid Po, dried yellow croacker and kong Jaban have cooked frequently. The proportion of subjects who has bought the marketed dried side dishes and Jaban products was 61.5%. Major problem of that products was pointed out for a sanitary condition and high price. If marketed dried basic side dishes and Jabans were improved over the aspects, the proportion of subjects who would buy the products was 70.0%. Preparation ability of these basic side dishes was influenced by age and educational level. The working housewives had higher frequency in use than the non-job housewives. The interesting degree for basic side dishes was not significantly different from age, resident area and educational level.

Typical misconceptions on Enterprise Resource Planning (ERP) among practitioners and researchers are reviewed. Companies can make, buy, or rent ERP solutions, but typically, ERP is conceived as ready-made, off the shelf application software package. The benefits of ERP adoption are frequently generalized without proper clarification of the requisite conditions. The specific outcomes of ERP adoption are not adequately differentiated from those of general computerization. To avoid the side-effects caused by those misconceptions, we 1) clarify the concept of ERP and the methods of sourcing it, 2) specify the requisite conditions for the benefits from packaged ERP solutions, and 3) explain the generic characteristics of ERP, direct effects and resultant possible outcomes of the adoption of ERP.

For a shunt power quality controller (SPQC) the DC side voltage value which is closely related to the compensation performance is a significant parameter. Buy so far, very little discussion has been conducted on this in a quantitative manner by previous publications. In this paper, a method to design the DC side voltage of SPQC is presented according to the compensation performance in the single-phase system and the three-phase system respectively. First, for the reactive current and the harmonic current compensation, a required minimal value of the DC side voltage with a zero total harmonic distortion (THD) of the source current and a unit power factor is obtained for a typical load, through the equivalent circuit analysis and the Fourier Transform analytical expressions. Second, when the DC side voltage of SPQC is lower than the above-obtained minimal value, the quantitative relationship between the DC side voltage and the THD after compensation is also elaborated using the curve diagram. Hardware experimental results verify the design method.

On information markets, we can identify different relations between sellers and their customers, with some users paying with money, some paying with attention, and others paying with their personal data. For the description of these different market relations, this article introduces the notion of arity into the scientific discussion. On unary information markets, customers pay with their money; examples include commercial information suppliers. Binary information markets are characterized by one market side paying with attention (e.g., on the search engine Google) or with personal data (e.g., on most social media services) and the other market side (mainly advertisers) paying with money. Our example of a ternary market is a social media market with the additional market side of influencers. If customers buy on unary markets, they know what to pay (in terms of money). If they pay with attention or with their personal data, they do not know what they have to pay exactly in the end. On n-ary markets (n greater than 1), laws should regulate company's abuse of money and-which is new-abuse of data streams with the aid of competition (or anti-trust) laws, and by modified data protection laws, which are guided by fair use of end users' attention and data.

The purpose of this study was to investigate the preferences, consumption, and eating frequencies of housewives for commercialized traditional basic side dishes. The investigators visited 18 food markets and questionnaires were distributed to 464 housewives in the Busan area. The number of basic side dishes being sold at the markets were in the order of seasoned dried radish (17 markets; mk), salted garlic stalk (15 mk), braised black soy beans (14 mk), braised peppers and dried anchovies (13 mk), and braised lotus roots (12 mk). The housewives' order of preferences was for stir-fried dried anchovies, braised peppers and dried anchovies, braised seasoned beef, salted perilla leaf, and perilla leaf kimchi equal to seasoned sea lettuce, respectively. The order for eating frequency was stir-fried dried anchovies, braised peppers and dried anchovies, salted perilla leaf, and perilla leaf kimchi, respectively. Salted perilla leaf, perilla leaf kimchi, braised crab preserved in soy sauce, salted bean leaves, seasoned dried radish, and seasoned crab were either occasionally or frequently purchased by over 40% of the women. However, the reasons they did not purchase these products included: the excess use of chemical seasonings, unsanitary, unreliable cooking process, unreliable the origin, and high price, in the respective order. If the commercialized traditional basic side dishes were improved to eliminate these problems, 52.2% of the housewives would buy the products, and 65.6% anticipated increasing their use of these products in the future.

This study was undertaken to investigate the knowledge and the use of Korea traditional basic side dishes, Jangachies, by housewives. Among the 58 kinds Jangachies, the most well-known Jangachies (above 80% of subjects) turned out to be Perilla leaf, Red pepper leaf, Garlic, Young stem of garlic, Green red leaf, Cucumber and dried Radish Jangachi in the order. In cooking experience of Jangachi, 40% of subjects in Perilla leaf, 28.0% in Green red pepper, 24.8% in Garlic and 24.1% in Red pepper leaf Jangachi have cooked frequently. The proportion of subjests who has bought the marketed Jangachi products were 51.6%. Major problem of that products was pointed out for a sanitary condition, high price and poor taste. If marketed Jangachies were improved over the aspects, the proportion of subjects who would buy the products was 76.2%. The frequency of Jangachi intake was very low on a average due to too salty taste and the difficulty in preparation. The older in age, the more in interest level for Jangachi (p<0.05). 39.6% of subject have had preparation ability of Jangachies. With increasing age (p<0.01), decreasing education level (p<0.01) and those who live in rural area (p<0.05), preparation ability of Jangachi tended to be higher.

The objective of this study is to examine the differentiated influence of sell-side advisors and buy-side advisors on mergers and acquisitions (M&A). Unlike prior studies on M&A advisors, the study addresses different roles of target and acquirer advisors, and explores their influences on the cumulative abnormal returns (CAR) and acquisition premiums with an empirical analysis of longitudinal data of M&As conducted by Japanese listed firms except financial companies from 1995 to 2012. M&A data were obtained from the Securities Data Corporation's (SDC) database, and the individual firm data were collected from the Nikkei Economic Electronic Databank System (NEEDS), which provides a wide range of corporate information including financial status, operational performance, and strategy. Using a sample of 452 cases for the CAR and 498 cases for the analysis of acquisition premiums, the empirical results support the hypotheses of the target advisor's positive association with CAR and acquirer advisor's positive association with acquisition premiums. The findings of this study indicate the target advisor's positive contribution to the success of acquisition process and performance, and acquirer advisor's negative influence on the deal progress. The study provides theoretical implications on M&A research and practical insights into the investment banking industry.

This paper illustrates the competition between the mobile pay and credit card systems by utilizing the theory of two-sided markets. Two firms, as platforms, maximize the profit collecting fees from consumers on one side and from retailers on the other side. Consumers pay to buy goods and services with mobile pay, credit card, or cash. The basic model is one that each platform maximizes its profit. We show that the fees for credit card holders and retailers are higher than the respective costs. The fee for retailers of the mobile payment is higher than its cost, while the buyer's fee may be higher or lower than its cost. Applied model is the one that employs the delegation game model. The total profit of the mobile pay system is composed of its profit and the weighted demand for the mobile pay. It is shown that buyers' fee under the applied model is lower than that under the basic model, resulting in an increase of the demand for the mobile pay. The fee for the retailers rises, albeit the sum of fees for the buyers and retailers falls. The profit for the mobile pay system is increased, while that for the credit card company stays the same.
