김신곤(Kim, Shinkon),서일정(Seo, Il-Jung) 한국전자상거래학회 2010 전자상거래학회지 Vol.11 No.2

상품의 브랜드 수가 지속적으로 증가하면서, 소매업체의 제한된 자원인 매대 공간을 효과적으로 관리하는 것이 소매업체의 중요한 과제가 되고 있다. 매대 공간 관리를 위한 전형적인 도구인 플래노그램을 효과적으로 설계하기 위해서는 상품의 진열위치 데이터를 수집하여 매대 수준의 판매 분석이 필요하지만, 기존의 매대 공간 관리 시스템은 전체 매장 수준의 판매 데이터와 상품 규격 정보만을 바탕으로 플래노그램을 작성하고 있다. 본 연구에서는 효과적인 매대 진열의 계획과 운영을 위하여 RFID 기술, 위치인식기술, BI 기술을 접목하여, 매대 수준에서 상품의 판매 상황을 수집하고 분석할 수 있는 RFID 기반의 플래노그램 시스템을 제안하였다. 또한 이를 위한 시스템 구성을 제안하고 차원 모델을 설계하였으며 활용 시나리오를 통해 그 유용성을 제시하였다. As a number of brands are increasing continuously in retail stores, retailers face a critical challenge that manages a limited shelf space effectively. To design a effective planogram which is a typical tool for managing shelf space, it is necessary to gather and analyze the detailed data for goods' locations and specifications displayed in the shelf. However, the current shelf space management systems implement a planogram based on overall sales volume and goods specification only. Combining RFID technology with localization and BI technology, this study proposes new RFID-based planogram system and develop its conceptual design. Also, system architecture and the dimensional model (star schema) of the data mart for the effective RFID-based planogram system are presented. Usefulness and applicability of the proposed systems are discussed through the application scenario.

정보통신 기술의 발전으로 농업분야에서도 다량의 데이터로부터 가치 있는 정보를 생성하고 그 활용을 위해 빅데이터 기술을 적용하는 연구가 활발히 진행되고 있다. 농업에서 재배 가능한 작물과 품종은 기온, 강수량, 일조시간 등의 자연환경의 영향에 따라 결정된다. 본 논문은 마늘의 생육과정과 일별로 측정되는 기상변수를 활용하여 농작물 생산에 영향을 미치는 기상기후 요인을 도출하고 마늘을 대상으로 단위면적당 생산량 예측(단수) 모형을 도출하였다. 기상변수는 마늘의 생육단계를 고려하여 빅데이터 분석 기법을 이용하였다. 탐색적 자료 분석과정에서는 통계청, 농촌진흥청, 농촌경제연구원으로부터 생산량, 도매시장 반입량, 생육 데이터 등 다양한 농산물 생산 데이터를 제공받아 활용하였다. 또한 기상청으로부터 AWS, ASOS, 특보현황 등 다양한 기상관측 데이터를 수집하여 활용하였다. 상관관계 분석 과정은 변수선택, 후보모형 도출, 모형진단, 시나리오 예측 등을 통해 도출한 모형의 모형 적합도와 생산량 예측력을 비교하여 마늘생산단수예측 모형을 설계하였다. 수많은 기상요인 변수는 요인분석을 이용하여 차원을 감소시키고 설명변수로 선정하였다. 이 방법을 이용함으로써 회귀분석에서 발생할 수 있는 다중공선성과 낮은 자유도의 문제를 효과적으로 통제할 수 있었으며 회귀분석의 적합도와 예측력을 높일 수 있었다. The development of information and communication technology has been carried out actively in the field of agriculture to generate valuable information from large amounts of data and apply big data technology to utilize it. Crops and their varieties are determined by the influence of the natural environment such as temperature, precipitation, and sunshine hours. This paper derives the climatic factors affecting the production of crops using the garlic growth process and daily meteorological variables. A prediction model was also developed for the production of garlic per unit area. A big data analysis technique considering the growth stage of garlic was used. In the exploratory data analysis process, various agricultural production data, such as the production volume, wholesale market load, and growth data were provided from the National Statistical Office, the Rural Development Administration, and Korea Rural Economic Institute. Various meteorological data, such as AWS, ASOS, and special status data, were collected and utilized from the Korea Meteorological Agency. The correlation analysis process was designed by comparing the prediction power of the models and fitness of models derived from the variable selection, candidate model derivation, model diagnosis, and scenario prediction. Numerous weather factor variables were selected as descriptive variables by factor analysis to reduce the dimensions. Using this method, it was possible to effectively control the multicollinearity and low degree of freedom that can occur in regression analysis and improve the fitness and predictive power of regression analysis.

Functional dyspepsia has been considered, until recently, to be a nebulous syndrome, in part because of the lack of a structural explanation for the symptoms and because of the apparent heterogeneity of the patients labeled with this diagnosis. Although many definitions have been offered, there is now reasonable consensus that dyspepsia refers to persistent or recurrent pain or discomfort that is centered on the upper abdomen ; the discomfort may be characterized by postprandial fullness, early satiety, nausea or upper abdominal bloating. The diagnosis of dyspepsia must not be restricted to those with meal-related symptoms because there is no clinical condition, including chronic peptic ulceration, in which the symptoms are exclusively confined to the postprandial period. The majority of the patients with chronic or recurrent dyspepsia do not have a peptic ulcer or any other recognized structural or biochemical abnormality that definitely explains the symptoms ; these patients are classified as having functional dyspepsia. Ideally, therapy for functional dyspepsia should be targeted at correcting an individual's underlying pathophysiologic disturbances. However, the mechanisms that produce symptoms in patients with functional dyspepsia remain poorly understood. A polyvalent digestive product Combizym� has a powerful combination of enzymes with broad activity and broad pH spectrum. It acts from the stomach to the small intestine and has a complete digestive effect on protein, carbohyrate and fat. We treated Combizym� in patients with functional dyspepsia with open, noncomparative study. The results are as follows ; 1. The improvement of the symptoms were 96.4 % in nausea and vomiting, 92.6 % in bloating, other symptoms were also improved over 75 %. 2. There was only mild pruritus in a patient and others were well tolerated during the experiment. 3. Overall improvement rate was 86.7 % of 30 patients. In conclusion, Combizym� is a safe and effective digestive drug in patients with functional dyspepsia.
