수요자의 필요에 즉각 대응하여 제품 및 서비스를 제공하는 온디맨드 경제(On-Demand Economy)에서는 수요자가 가격 결정에 상당한 영향력을 가진다. 여행 관련 분야에서도, 서비스 제공자가 수요자의 요구를 반영하고, 더 나은 서비스를 제공하기 위해 많은 노력을 하고 있다. 본 논문에서는, 판매자가 일방적으로 가격을 결정하는 다수의 여행 관련 서비스 플랫폼과는 달리, 수요자가 여행 관련 서비스 및 가격을 제안하는 역경매 기반의 서비스 플랫폼 방식을 제안하였다. 제안된 매칭 서비스 플랫폼은 다양한 수요자의 요구를 분석하고, 수집된 경험 데이터를 반영하여, 기존의 정형화된 여행 관련 서비스와 차별화된 양방향 서비스 창출이 가능할 것으로 기대된다.

Animal welfare has been gradually gathering more attention from consumers over time, making it increasingly important to assess the level of stress experienced by livestock. Traditionally, stress has been measured by collecting blood to assess cortisol levels, an action that can be considered distressing for the animal. Therefore, we aimed to explore the feasibility of using hair as an alternative medium to blood for stress assessment. We utilized B/F (blood collected at the farm), B/A (blood collected after transport to the auction), and H/A (hair collected at the auction after blood sampling) from calves at the age of 7-9 months transported from the farm to the auction. Hair underwent a washing and extraction process to utilize hair extracts, while blood was centrifuged to analyze using ELISA. The cortisol concentration in the blood was significantly higher in B/A compared to B/F (p<0.05), confirming that the calves experienced stress during transportation. Additionally, H/A was significantly lower than both B/A and B/F (p<0.0001). These results emphasized that cortisol in hair is not suitable for investigating short-term stress in livestock, as it is with blood. While measuring stress indices using hair may not be appropriate for replacing blood, it is considered a highly suitable practice for animal welfare, and further research in this area should be continued.

Purpose - The Garak agricultural wholesale market ('Garak Market') plays a central role in the distribution of agricultural products in Korea and is important in connecting consumers with producers. However, problems regarding inefficiencies and the high-cost structure of the wholesale market's distribution/logistical system are being raised in relation to severe competition among retailers. Furthermore, the service needs of retailers and market users are not being fulfilled due to the inconsistency of the wholesale market's functions and facilities, thus reducing the competitiveness of the market. In this regard, innovative changes are being requested of the agricultural wholesale market according to changes in the agricultural product distribution environment. In particular, the lack of unloading facilities and the outdated unloading system of the wholesale market must be improved to enhance system efficiency. Research design, data, and methodology - This study observed the problems of the unloading system of the agricultural wholesale market in order to present relevant measures for improvement. The need for unloading auctions was also researched in this study. The survey of 70 forwarders belonging to the producing district distributor association of the Garak market was conducted by post. Additionally, 20 auction dealers and 59 shippers and transporters were individually interviewed. The survey on the need for unloading auctions used five-point Likert Scales. The statistical analysis was conducted with SPSS WIN 12.0 software. Results - First, the wholesale market must employ members of the unloading labor union to allow these employees to directly manage the unloading process. Second, it is crucial to revise regulations to ensure that the principal agent pays the unloading cost according to the standard unloading cost system. Third, the vehicle auction carried out for certain vegetable products must be converted to the unloaded auction system. According to the related interviews with the wholesale market's distribution agents, whereas shippers and transporters recognized the need for unloaded auctions, auction dealers tend to have a negative view of this system. Furthermore, the stated reasons in favor of unloaded cabbage, radish, and other vegetable auctions were prevention of constraint, creation of transparent trade conditions, and reduction of corrected seller tickets. Many of the respondents answered that the transport cost reduction rate in unloaded auctions must be below 20%. Fourth, the unloading system must be mechanized and a detailed, reasonable plan must be provided to settle the existing conflict with the unloading labor union. Conclusions - The proposals in this study are expected to play an important role in improving the cargo handling system of the wholesale agricultural product market in the future. Improving the system is expected to help shore up the competitiveness of the industry. If all the related bodies closely cooperate with each other and work harder, taking advantage of the synergies created by the facility modernization project, the Garak market will play a pivotal role in the distribution of agricultural products.

미술품의 가격결정 요인에 대한 연구는 그 동안 작가나 작품 소재 등 변하지 않는 요인들이 주로 다루어져 왔다. 그러나 미술품은 자산의 기능을 가지고 있고 거래 가능하기 때문에 다양한 외부 요인 변화에 의해 가격이 영향을 받게 된다. 본 연구는 국내 미술 경매 시장에서 주목을 받고 있는 '단색화'가 대중에게 인지도가 상승함에 따라 작품 가격이 변화하는 양상을 분석하고자 한다. 이를 위해 (사)한국미술시가감정협회에서 선정한 낙찰 총액 상위 20명 화가의 12년간의 미술 경매 자료(4,199개 표본)에 이중차감모형(DiD)을 적용하여 추정하였다. 분석 결과, 단색화 인지도 상승으로 인해 약 71%의 가격 효과가 나타났다. 또한 작가의 특성에 따라 인지도 상승으로 인한 가격 효과가 다르며, 시간이 지남에 따라 인지도가 가격에 미치는 효과가 증가하는 것으로 나타났다. 이상의 결과는 인지도, 시장 저변 등에 영향을 미칠 수 있는 정보 제공이 예술시장 정책에 있어 중요하다는 것을 보여준다. 현재 한국 미술계나 미술시장에서 한국 작가 및 작품의 인지도 및 평가가 상당히 저조한 것을 볼 때 미술품의 대중적 인지도 상승 노력이 미술시장의 대중화와 함께 시장규모를 확대시키는데 유용한 방안이 될 수 있다.

The aim of this study was to identify the factors contributing to the auction price and total price of carcasses by using squared semi-partial correlation of carcass traits. The data used in this study were the carcass grades assigned to 7,145 head of Hanwoo slaughtered from 2013 to 2018 in Gyeonggi province and 106,779 head of Hanwoo slaughtered from 2013 to 2018 outside of Gyeonggi province. The rankings of the carcass traits contributing to the auction price were in the order of marbling score (86.70%), backfat thickness (10.42%), eye muscle area (1.40%), and carcass weight (0.92%) in Gyeonggi province. In Hanwoo slaughtered outside of Gyeonggi province, the rankings were in the order of marbling score (88.53%), backfat thickness (9.06%), eye muscle area (1.24%), and carcass weight (0.99%). The rankings of carcass traits contributing to the total price were in the order of marbling score (45.95%), carcass weight (45.60%), backfat thickness (6.49%) and eye muscle area (0.77%) in Gyeonggi province. In Hanwoo slaughtered outside Gyeonggi province, the rankings were in the order of marbling score (49.64%), carcass weight (43%), backfat thickness (5.86%), and eye muscle area (0.66%). Gyeonggi province Hanwoo had thinner backfat thickness than Hanwoo outside Gyeonggi, and it had a higher contribution to auction price and total price. Collectively, Hanwoo in Gyeonggi province showed higher contribution scores for backfat thickness. This study aimed to provide basic information to guide Hanwoo breeding and increase profits for Hanwoo farms through the analysis of each traits according to environmental factors.

As a way to allocate lots of orders to many participants for vehicle allocation problem, this study has used an agent negotiation based reverse auction model. This agent negotiation provides coordination functions allowing all participants to make a profit, and accomplishing Pareto optimum solution from the viewpoint of a whole trucking cargo transportation network. In order to build a strategic cooperation relationship based on information sharing, this agent negotiation provides a coordination mechanism in which all the participants including consignors, brokerage firms, and car owners are able to attain their own profits, and also that ensure a competitive market. This study has tried to prove that the result of an agent-based negotiation is the Pareto optimal solution under the present market environment. We established a mathematical formulation for a comparison with the Integer Programming model, and analysing e-Marketplace, structure of shipping expenses and brokerage system in the trucking cargo transportation industry.
