The Act on Distribution and Price Stabilization of Agricultural and Fisheries Product, which specifies rules and regulations on the trading system of fishery products wholesales markets, has been revised several times, mainly in order to improve the trading system. However, there is still a huge gap between the reality and law when it comes to the trading system of the fishery products wholesale market. This study aims to analyze the problems of the trading system of the fishery products wholesale market and to suggest ways to make improvement. The main problem facing the trading system of the fishery products wholesale market is sales on consignment by intermediate wholesalers, and this paper suggests two alternatives to solve the problem. First, intermediate wholesaler can be converted to market wholesalers, but it also entails other problems. The market wholesaler system has never been successfully adopted in the agricultural and fishery products wholesale market, and it is not clear which system is better between the wholesale market corporation and the market wholesaler system. Second, sales on consignment by intermediate wholesalers can be adopted with a positive view toward it. Negotiation transaction can be carried out for sales on consignment as a transaction method under the current Act on Distribution and Price Stabilization of Agricultural and Fisheries Products. However, since the act cannot provide a solution for listing, it is necessary to introduce Japan's negotiated transaction in advance system as a negotiation transaction method.

Switching to organic farming practices in agricultural production reaches the end of the period it takes an average of five years. During this period, agricultural soil management to improve the investment must be sustained. Results of the survey of environment-friendly agricultural lease rates appear to approximately 54.2% lower than agricultural practices. Environmentally friendly agricultural land is leased on a long transition period of the contract cost, many buried incompleteness, uncertainty of contract fulfillment(opportunistic behavior) occurs when the transaction costs. This ultimately can hinder the spread of organic farming. Thus, the qualitative development of organic farming and land leasing in order to minimize transaction costs, should that occur. The alternative 'cooperative long-term lease contract' is a system.

An efficient agricultural marketing system is very important to producers and consumers to keep the reasonable prices. In these days, the main policy for the efficient agricultural marketing system is to enlarge the direct transaction market. But it is not easy to enlarge the direct transaction market in a few years. This paper proposes a new efficient agricultural marketing system that gives a similar effect with the direct market. The proposed system is mainly composed of three associations; producers', consumers' and retailers'association, and the function of the system is devided into material affairs and commercial affairs. The structure of the system also can be simplified as two to three steps. So the system can reduce the cost of logistics and keep the reasonable prices for both producers and consumers.

정보기술의 빠른 진화, 빅데이터의 등장, 분석기법의 고도화 등으로 인해 다량의 데이터로부터 의미있는 정보를 추출하는 데이터마이닝을 다양한 영역에 활용하고자 하는 시도들이 활발히 진행되고 있다. 그 중의 한 분야가 농산물 유통영역인데, 농산물에 대한 지속적인 수요 증가와 전자경매의 활성화 등으로 수도권 농산물 도매시장에서만도 연간 수천만건 이상의 거래가 이루어 진다. 그러나 급속한 거래량 증가와 더불어 과거로부터 관행적으로 이루어지고 있는 부정거래도 함께 증가하고 있는데 거래참가자들 사이의 결탁에 의해 발생하는 농산물 도매시장의 부정거래는 점차 지능화되는 추세이며, 이들을 감지하고 적발하기가 매우 어려운 실정이다. 이로 인해 농산물 유통환경의 공정거래 질서는 침해되고 시장에 대한 신뢰는 훼손되곤 한다. 따라서 거래투명성을 제고하고 유통비리를 구조적으로 개선하기 위한 과학적이고 자동화된 부정탐지시스템의 필요성이 어느 때보다도 절실히 요구되는 상황이다. 본 연구에서는 데이터마이닝의 의사결정나무를 이용하여 실제 발생하지 않은 거래를 실물 없이 거래한 것처럼 조작하여 대금을 정산하는 행위인 허위거래를 탐지하는 모형을 제시하였다. 이를 위해 실제 농산물 도매시장의 데이터를 수집하였고, 데이터의 정제 및 표준화 등의 선행작업을 수행하였다. 또한 변수 간의 상관관계 및 분포도 분석 등을 통해 데이터의 특성을 파악한 후 예측모형을 구축하여 허위거래와 정상거래를 분류하는 패턴을 도출하였으며, 최종적으로 시험용 데이터를 이용하여 모형을 평가하는 단계를 거쳐 결과의 적합성을 확인하였다. 향후 데이터마이닝을 이용한 부정탐지 모형을 허위거래뿐만 아니라 낙찰부정, 경매조작 등과 같이 다양화되는 부정거래에 적용하게 되면 보다 지대한 효과를 거둘 수 있으리라 사료된다.

기업 의사 결정 지원을 위하여 거래 데이터를 다양한 관점에서 분석하고 활용하려는 노력과 관심들이 증가하고 있다. 이러한 노력들은 고객 관리나 마케팅에만 국한되는 것이 아니라 부정행위에 대한 감시와 탐지를 목적으로도 다양한 분석 방안들이 연구되고 있다. 부정행위는 기술의 발전을 악용하여 다양한 형태로 진화하고 있으며, 이에 따라 목적에 맞는 부정탐지 방안 연구와 적용을 통하여 탐지 효용의 극대화를 위한 노력의 필요성이 증가하고 있다. 이러한 연구 동향의 일환으로 본 연구에서는 대용량 거래 데이터가 저장 관리되고 있는 국내 최대 농수산물 유통 시장의 2008년부터 2010년까지 상장예외품목의 거래 가격을 분석하여 부정 탐지 규칙을 도출하였으며, 전문가 검증을 통하여 도출 된 규칙의 신뢰성을 확보하였다. 본 연구의 주요 부정거래 분석 방안으로는 정상적인 데이터들은 발생 확률이 높은 반면에 특이한 데이터들의 발생 확률은 낮다고 가정하는 통계적 접근을 통한 이상치 식별 방안을 활용하였다. 이에 따라 부정거래 분석 별로 정의 된 Z-Score 값보다 클 경우 부정거래 탐지 대상이 된다. 다만 상장예외품목 거래의 경우 취급 가능한 중도매인의 수가 제한되어 있으며, 일반적인 상장품목의 거래보다 거래량이 적기 때문에 소수의 이상치가 품목의 평균에 미치는 영향이 크다. 그 예로 다른 소수의 중도매인들이 해당 품목을 정상적인 가격에 거래하였더라도, 특정한 중도매인 한 명이 지나치게 비정상적인 가격에 거래할 경우 모든 거래들이 부정거래로 탐지 될 가능성도 있다. 이러한 문제를 해결하기 위하여 기존의 Z-Score의 개념을 활용하여 수정된 Z-Score(Self-Eliminated Z-Score)를 사용하였다. 또한 부정 유형별 탐지 규칙 관리와 활용을 위한 시스템 프로토타입(prototype) 개발을 수행하였다. 이를 통하여 실제 부정거래 탐지 업무에 적용할 수 있는 효과적인 방안을 제시하였고, 농수산 유통시장의 공정성 및 투명성 확보를 위한 관리 감독의 기능 강화가 가능할 것이다.

In this paper, a design and implementation for direct deal distribution platform is proposed to bypass the complex traditional distribution structure of agricultural market, as one of the fields where distribution patterns have changed. In the case of domestic agricultural distribution, demand and supply are unstable since the sales market is excessively concentrated in the designated wholesale market. Besides sales must go through multiple stages of distribution leading to problems in freshness and stability of agricultural products and downward pressure on profit margins for producers. To solve the above mentioned issues, we propose a cloud service convergence direct deal distribution platform based on asynchronous-driven Node.js. The proposed platform can facilitate a variety of direct trading functions and also access to visualization information related to agricultural products, which may increase user confidence at an intermediary-free direct transactions platform. First, we describe the requirements of intermediary-free direct transactions of agricultural products and transaction entities. Next the database structure and transaction functions are designed and then implemented according to those requirements. Finally, an API based cloud convergence service structure is designed to provide the analyzed information to ensure a trustworthy system.

The objective of this study is to investigate the determinants of trust between the producer and the distributor, focusing on relational norms (mutuality, flexibility, and solidarity) and environmental munificence, in agricultural marketing channels. More specifically, followings are investigated in cucumber marketing channels ; (a) the effects of environmental munificence on relational norms, and (b) tile effects of relational norms on trust. The major findings of this study are as follows ; (1) The cucumber producers' perceived output sector munificience positively affected the mutuality and solidarity of the relational norms. (2) The mutuality and solidarity of the relational norms positively affected the trust. Therefore, the efficient marketing transaction system, mutual efforts for a fair regard between producers and middlemen, and the development of sound moral and trading custom are required in the Korean agricultural market. And also the active roles of government to develop the infrastructure of agricultural marketing and the proper roles of agricultural cooperatives to keep transaction activity fair should be clarified and proactively conducted.

Objectives: This research analyzed and compared housing transaction prices and depression rates according to housing types before and after the COVID-19 pandemic. Methods: Data on housing transaction prices and depression rates from 2018 to 2022 in 25 districts of Seoul, South Korea, were utilized. Dummy variables were employed to account for potential confounders influencing the relationship between the variables. Statistical analysis was conducted using R, and the relationship between depression rates and housing transaction prices was examined through Ordinary Least Squares (OLS) and panel data regression analysis. Results: The results of OLS and one-way random effects models indicated a significant relationship between apartment (p<.05) and officetel (p<.001) transaction prices and depression. However, detached/semi-detached and row/townhouse transaction prices did not exhibit a significant relationship with depression. Conclusion: It was observed that as apartment and officetel transaction prices increased in Seoul before and after the COVID-19 pandemic, depression rates also increased. Considering that changes in housing prices by housing type in South Korea may impact the mental health of local residents, it is deemed necessary to consider healthy housing and housing prices as comprehensive determinants of mental health.
