Despite of increasing studies for product recommendation, the recommendation of product repurchase timing has not yet been studied actively. This study aims to propose deep neural network models usingsimple purchase history data to predict the repurchase timing of each customer and compare performances of the models from the perspective of prediction quality, including expected ROI of promotion, variability of precision and recall, and diversity of target selection for promotion. As an experiment result, a recurrent neural network (RNN) model showed higher promotion ROI and the smaller variability compared to MLP and other models. The proposed model can be used to develop a CRM system that can offer SMS or app-based promotionsto the customer at the right time. This model can also be used to increase sales for product repurchase businesses by balancing the level of ordersas well as inducing repurchases by customers.

Along with the recent trend toward increasing variety and shorter life of products in the market, evaluation of risk for economic investment alternatives is of practical importance in manufacturing companies. This paper assumes that each alternative is composed of demand volume and unit sales price as income factors, and unit variable cost and fixed cost as expense factors. The paper assumes that these four factors move worse from the originally expected values, toward the direction of decreasing profit. Values of these four factors are also assumed to fluctuate from year to year over the entire multi-period. By applying the analysis of the breakeven points to each of the four factors, safer area against these changes is represented on the two dimensional domain called normalized total-cost unit-cost domain. A practical numerical example is analyzed to verify the validity of the proposed method.

As with land crops, cultivated algae are affected by various diseases ranging from large outbreaks of a disease to chronic epiphytes, which may downgrade the value of the final product. The recent development of intensive and dense mariculture practices has enabled some new diseases to spread much faster than before. A new disease is reported almost every year, and the impact of diseases is expected to increase with environmental change, such as global warming. We observed the incidence of diseases in two Pyropia sea farms in Korea from 2011 to 2014, and estimated the economic loss caused by each disease. Serious damage is caused by the oomycete pathogens, Pythium porphyrae and Olpidiopsis spp., which decreased the productivity of the Pyropia sea farms. In Seocheon sea farms, an outbreak of Olpidiopsis spp. disease resulted in approximately US $1.6 million in loss, representing approximately 24.5% of total sales during the 2012-2013 season. The damage caused by green-spot disease was almost as serious as oomycete diseases. An outbreak of green-spot disease in the Seocheon sea farms resulted in approximately US $1.1 million in loss, representing 10.7% of total sales in the 2013-2014 season in this area. However, the causative agent of green-spot disease is still not confirmed. "Diatom felt" is regarded as a minor nuisance that does not cause serious damage in Pyropia; however, our case study showed that the economic loss caused by "diatom felt" might be as serious as that of oomycete diseases. Bacteria and cyanobacteria are indigenous members of epiphytic microbial community on Pyropia blades, but can become opportunistic pathogens under suitable environmental conditions, especially when Pyropia suffers from other diseases. A regular acid wash of the Pyropia cultivation nets is the most common treatment for all of the above mentioned diseases, and represents approximately 30% of the total cost in Pyropia sea farming. However, the acid wash is ineffective for some diseases, especially for Olpidiopsis and bacterial diseases.

본 연구는 주유소와 가전제품취급점이 직영점과 대리점의 양대 유통체제를 가지고 있다는 사실에 착안하여 갈등발생요인과 갈등과의 관계, 갈등이 경영성과에 미치는 영향을 파악하므로써 유통환경내에서 중점적으로 관리되어야 할 갈등원인을 규명하고 이에 따른 갈등이 경영성과에 미치는 영향을 파악해 보고자 하였다. 본 연구의 분석결과를 요약해 보면, 첫째, 주유소와 가전제품취급점이 갖고 있는 갈등원인 중 힘의 불균형, 본사의 역할불이행, 가맹점의 역할불이행, 지각의 차이, 의사소통의 장애는 갈등과 정의 관계를 가지나 역할명확성은 갈등과 부의 관계를 가지는 것으로 나타났으며 이러한 결과는 본사의 일방적 힘의 행사정도가 강할수록, 본사와 가맹점이 서로의 역할을 수행하는 정도가 떨어질수록, 가맹점 취급의 공정성이나 가맹점 지원이 부족할수록, 가맹점 요청에 대한 반응이 부적절하거나 정보의 전달정도가 떨어질수록 갈등이 더 많이 발생한다는 것을 의미한다고 할 수 있겠다. 또한 갈등에 가장 큰 영향을 미치는 갈등원인은 의사소통의 장애로 나타났으며 마지막으로 본 연구의 유통관리적 의미와 시사점에 대하여도 기술하였다.
