Recent market competition forces the price to be determined in the design stage so that the design would meet the target price of the product. However, most commercial PDM(Product Data Management) systems currently in use lack such a cost estimation function. In this paper, we propose detailed structure and functions of a new approach to estimate the cost of new products using integrated BOM in PDM. Such system will reduce the total life cycle cost of the products to be designed.

We analyze the effects of the sellers' strateiges on the final bid prices in internet auctions. We focus on the following three strategies of the seller adoption of the buy-price, setting the starting bid price, and adoption of 'the effective fixed price' which means that the starting bid price is set near the buy-price. In addition, the number of units sold single-unit or multi-unit, and item characteristics, such as whether the food is a search product (functional product) or an experience product (non-functional product), are also considered. We use real data on bids for 4 items from an online auction site. We find that in an auction for experience products when sold as single units, adopting the buy-price strategy raises the final bid price. We also find that in multi-unit auctions, starting the auction at 'the effective fixed price' raises the final bid price.

It is difficult to determine an appropriate discount price for daily perishable products to increase profit from a long-term standpoint. Even if the discount pricing is efficient to increase profit of the day, consumers memorize the sales price and they might hesitate to purchase the product at a regular price the following day. The authors discussed the inventory clearance pricing for a single period in our previous study by constructing a mathematical model to derive an optimal sales price to maximize the expected profit by considering the reference price effect of demand. This paper extends the discussion to handle the discount pricing for multiple periods. A mathematical analysis is first conducted to reveal the properties on an objective function, which is the present value of total expected profits for multiple periods. An algorithm is then proposed to derive an optimal price for asymmetric consumers. Numerical experiments investigate the characteristics of the objective function and optimal pricings.

Garlic and onion are staple agricultural products to Koreans and also are important with regard to agricultural producers' income. These products' acreage responses are highly correlated with each other. Therefore, it is necessary to test whether there is a cointegration relationship between garlic acreage and onion acreage when one tries to estimate the acreage response's function. Based upon the test result of cointegration, it is confirmed that there is no statistically significant cointegration relationship between garlic acreage and onion acreage. In this case, vector autoregressive model is preferred to vector error correction model. This study investigated the dynamic relationship between garlic and onion acreage responses using vector autoregressive (VAR) model. The estimated results of VAR acreage response models show that there is a statistically significant relationship between current and lagged acreage of more than one lag. Therefore, it is recommended that government should consider the long-run period's relationship of each product's acreage when it plans a policy for stabilizing the supply and demand of garlic and onion. For the price variables, garlic price only affects garlic acreage response while onion price affects not only onion acreage response but also garlic acreage response. This implies that the stabilizing policy for onion price could have bigger effects than that for garlic price stabilization.

Hangwa is a traditional food, corresponding to the current consumption trend, in need of marketing strategies to extend its consumption. Therefore, the purpose of this study was to analyze consumers’ consumption patterns and perception of Hangwa to increase consumption in the market. A questionnaire was sent to 250 consumers by e-mail from Oct 8~23, 2009 and the data from 231 persons were analyzed in this study. Statistical, descriptive, paired samples t-test, and importance-performance analyses were conducted using SPSS WIN 17.0. According to the results, Hangwa was purchased mainly 'for present' (39.8%) and the main reasons for buying it were 'traditional image' (33.3%) and 'taste' (22.5%). When importance and performance of attributes considered in purchasing Hangwa were evaluated, performance was assessed to be lower than importance for all attributes. The attributes in the first quadrant with a high importance and a high performance were ‘a sanitary process’, ‘a rigorous quality mark’ and ‘taste’, which were related with quality of the products. In addition, those with a high importance but a low performance were ‘popularization through advertisement’, ‘promotion through mass media’, ‘conversion of thought on traditional foods’, ‘a reasonable price’ and ‘a wide range of price’. In conclusion, Hangwa manufacturers need to diversify products and extend the expiration date based on technologies to promote its consumption. In terms of price, Hangwa should become more available by lowering the price barrier for consumers who are sensitive to price.

본 연구의 목적은 우리나라 김 산지 수출량 결정 모형을 개발하는데 있다. 모형의 설명변수에는 국내시장의 연도별, 월별 생산물량과 산지가격, 그리고 수출가격과 환율이 포함되었다. 추정 결과 김 수출은 단기적인 생산량의 증가 보다 장기적인 생산량의 증가에 더 큰 영향을 받는 것으로 나타났다. 또한 환율이나 수출가격이 상승할 경우 수출량이 탄력적으로 반응하였다. 반면에 산지가격이 상승할 경우 김 수출은 감소하나, 비탄력적인 모습을 보였다. 따라서 김의 수출을 증가시키기 위해서는 중장기적인 생산량 증대를 위한 기반시설 확립, 수출가격이나 환율변동에 대한 보다 정확한 예측 및 관련 정보제공이 중요하다고 판단된다.

The objectives of this study were to investigate the consumers' general perceptions and attitudes in response to the leaflet fashion advertisements, and to examine how much differently the level of price and the advertisement type affect brand images and consumers' buying intentions. Subjects for this study were 192 female university students in the twenties. Through the pre-test, several casual brands with such various the level of price as high, middle. and low were selected. Stimuli consisted of 8 photographs of the advertisements types which were manipulated according to the price level(highㆍmiddle & low) and the advertisements type(generalㆍleaflet). The results showed that consumers got the information on the fashion products mostly from the advertisements in magazines. It was also found that consumers showed the highest interests on the design and the discount rate of prices in the leaflet fashion advertisements. The price range(highㆍmiddle & low) of casual brands had significantly affected on the brand image and the consumers' buying intention. And the higher the prices of casual brands were, the worse brand images were when products were advertised by fashion leaflets. The advertisements types(generalㆍleaflet) gave some influences only on the brand image. Based on these results, marketing strategies of fashion advertising would be ,suggested.

This study investigated the effects of imported fisheries products on WTO/DDA tariff negotiations. To calculate the results, the study estimated the demand functions of imported fisheries products by using unit root and cointegration approaches. These approaches allowed us to solve spurious regression problems with macro-economic variables. In addition, this study surmised the effects of change by individually imported fish products from a tariff negotiation model using price elasticities of estimated import demand function. In a process of the analysis for estimating import effects, this study found out that 39 out of 128 imported fish products had positive (+) price elasticities or did not exhibit cointegrations. To cure this problem, this study suggested that the effects of these 39 imported products be estimated with the average variation rate of import volume, rather than by the Ordinary Least Squares approach. In this study, a case-study of tariff formula with coefficient 8 based on a 'Swiss formula' for priority duty rate of 2001 and 2008 was used by to analyze the effect of change in the 128 imported fish products of both years, respectively.

This study is for the development of fashion cultural products that simultaneously evolved with the contemporary use of traditional temple culture in addition, it analyzed the cultural products available in the Korean market. Methodology, this study conducted a literature review and empirical research. We targeted the cultural products carried at twelve web-based shopping malls for Buddhist cultural products and six souvenir shops in Korean Buddhist temples to collect data on those products in order to analyze the items, design motives, materials, and price ranges. The study results showed that interior items represented the largest portion of the targeted goods, followed by accessories/sundries, clothing/fashion items, stationery, and tableware. The most commonly used design motive was lotuses, followed by the images of Buddha or Buddhist Goddesses and Dharma. The most common materials include fibers, jewelry (such as gold and silver), wood, metals, ceramics, paper, and plastic. The most active price range was between KRW10,000 and KRW50,000, followed by less than KRW10,000 and KRW100,000 to less than KRW500,000. This study discovered the potential for traditional temple culture to advance it further in a contemporary manner and indicated the need to develop a wide variety of cultural products and emphasize its global acceptance.

As social distancing strengthened after the COVID-19 incident, people looked for things they could do alone. Additionally, as people have more financial resources, they purchase products they had previously considered purchasing, and the phenomenon of giving gifts to oneself has also appeared. Accordingly, this study analyzed fashion product reviews of KakaoTalk Gift, the service to exchange gift via SNS mobile app, to discover the phenomenon of self-gifting and the differences from interpersonal-gifting. For post-hoc data, in collected 18,354 pieces after excluding unnecessary data using a Python-based web crawling technique. The self-gifting behavior of KakaoTalk Gift different from the previous study for self-gift. Regardless of the gift-giving contexts, it determines that most self-gift products are material items. There are differences in product types and price levels when choosing gifts for others and oneself. As a self-gift, people typically buy luxury jewelry and branded bags/wallets to wear and show off. As interpersonal, among fashion products, people usually buy beauty products that reflect less personal tastes. When gift-giving to others, people buy products to appropriate prices to reduce the burden on both. When gift-giving to oneself, people buy wanted products regardless of the price. This study is significant because it suggests a new direction in self-gift research by limited online places to give gifts.
