There have been emerging many use-cases applying recommendation systems especially in online platform. Although the performance of recommendation systems is affected by a variety of factors, selecting appropriate features is difficult since most of recommendation systems have sparse data. Conventional matrix factorization (MF) method is a basic way to handle with problems in the recommendation systems. However, the MF based scheme cannot reflect non-linearity characteristics well. As deep learning technology has been attracted widely, a deep neural network (DNN) framework based collaborative filtering (CF) was introduced to complement the non-linearity issue. However, there is still a problem related to feature embedding for use as input to the DNN. In this paper, we propose an effective method using singular value decomposition (SVD) based feature embedding for improving the DNN performance of recommendation algorithms. We evaluate the performance of recommendation systems using MovieLens dataset and show the proposed scheme outperforms the existing methods. Moreover, we analyze the performance according to the number of latent features in the proposed algorithm. We expect that the proposed scheme can be applied to the generalized recommendation systems.

Although the Internet has been a important communication tool in modern societies, researchers did not pay attention to its' positive impacts on individual's psychological process. The Internet provides users with a unique environment such as visual isolation, non face-to-face communication, and easiness to escape from social influences. This environment enables people to take free action according to their personality and disclose themselves. From the uses and gratification perspective, the current research reveals that individuals with high extraversion are inclined to maintain social networking sites and those with high openness participate in web communities. The findings indicate that individuals' social use of the Internet may reflect their personality. To fill the research void like this, this study proposes a new research model in which well bing as well as perceived value are positively linked to satisfaction and continuance to use. The statistical results obtained by applying PLS to the valid 150 questionnaires showed that the well bing has stronger positive influence on satisfaction and continuance to use than the perceived value. Therefore, a practical implication is suggested that the web site need to be designed in a way of arousing users' well bing more strongly.

Purpose - This paper examines the value relevance of socially responsible activities in the Korean retail firms. Recent studies predict positive relationships between socially responsible activities and the value of corporation. Research design, data, and methodology - We use the environmental score, social score, governance score and the sum of these three scores to represent a fim's effectiveness of socially responsible activities. These scores are published by the Korean Corporate Governance Service. This paper adopts a share price valuation model to evaluate the effect of socially responsible activities on a firm's share price, which controls for the book value of assets and current earnings. The ordinary least square method is employed to examine the relationship. The sample of Korea retail firms is examined from 2011 to 2016. We also conduct sub-sample analysis based on the categorization of chaebol affiliates and non-chaebol affiliates. Results - The entire sample analysis finds neither negatively nor positively significant relationship between socially responsible activities and the value of a corporation. In contrast, our examinations find a significantly positive valuation effect of social score within non-chaebol retail firms. Conclusions - The results weakly support the positive valuation effect of socially responsible activities. The results are consistent with recent studies that highlight heterogeneous effects of socially responsible activities on corporate policies and valuation.

The reviewing of an analysis of the Korea-China FTA due to guidance introduced for the new regulations or exceptional regulations compared to the KORUS, Korea-EU, Korea-ASEAN FTA. Commodity sectors in the Korea-China FTA and the KORUS, Korea-EU, Korea-ASEAN FTA(the majority in the country and trade criteria analysis result) compared and analyzed the results, rules of origin and the customs clearance procedures of origin, preferential tariff rate of origin and the origin preferential specific rules are somewhat difference, but customs and trade facilitation regulations are already quite consistent with the Korea customs system. Relatively important research results were as follows. First, the calculation of the regional value content in KORCHINA FTA is that I'm to use the deduction method can comprehensively reflect a regional value ratio, with respect to the materials acquired originating status as the FTA in the US and EU use the product non it's not to consider the value of the originating materials originating materials can be utilized for intermediate goods. Second, even if a non-treaty country in the middle with the exception of direct transport rules, and acknowledge the country of origin are under customs control, there are provisions for the period are temporarily stored in a non-treaty countries separately, that period goods imported into the non-treaty countries and up to three months from the day. If the situation of the occurrence of force majeure be greater than three months, but has so exceed six months. Third, the materials acquired originating status in the Korea-China FTA not to consider the value of non-originating materials used in its products as the KORUS FTA and Korea-EU FTA, that can be utilized originating materials for intermediate goods. It is expected that higher utilization of rules of origin. Meanwhile, Korea-China FTA has provisions to allow requests for preferential tariff applied on imports Customs declaration of intention to apply pre-condition for a preferential tariff applied to the importer. In other words, if the import customs tariff preference when applying post-intention not to advance is to be noted that any preferential treatment to prevent the later application.

Farmers need timely information on the nutritional status of their animals and the nutritive value of pastures and supplementary feeds if they are to apply successfully this existing nutritional information. Near infrared reflectance(NIR) spectroscopy has been used over the last forty years to analyse accurately protein, fiber, and other organic components in animal foods. NIR spectroscopy is a rapid, non-destructive, and non-polluting technology. When properly calibrated, NIR spectroscopy is used successfully with both concentrate and forage feeds. NIR methods predict in vitro digestibility accurately and precisely, and can predict in vivo digestibility at least as well as conventional "wet chemistry" methods such as in vivo digestion or the pepsin-cellulase method, and much more rapidly. NIR technology has been applied to the routine monitoring (through analysis of feces samples) of the nutritional status of cattle and other grazing animals. This report reviews the use of near infrared reflectance(NIR) spectroscopy to monitor the nutritive value of animal feeds and the nutritional status of grazing animals.

Purpose In 2016, the market size of mobile(m-) shopping goes beyeond more than half of a total of online shopping. People use smartphones as the main device for m-commerce. Under the circmustances, this study attempts to address why people prefer to use smartphone-based m-commerce. In other words, it is necessary to understand the main value that smartphone-based m-commerce creates. Drawing on the studies of consumption value, this study focuses on utilitarian value in predicting customers' continuance intention in the context of smartphone-based m-commerce, recognizing that utilitarian value is a key extrinsic motivation in the goal-oriented, performance-oriented shopping contexts. Furthermore, this study identifies factors affecting customers' utilitarian value from the perspective of benefits and costs, following the notion that it represents the result of evaluating a trade-off of benefits and costs caused by smartphone-based m commerce. More specifically, in this study, ubiquitous service, location-based service (LBS), transaction speed, and price utility belong to the benefit dimension, whereas technology anxiety and cognitive effort belong to the cost dimension. Design/methodology/approach To test the proposed hypotheses, the study conducted partial least squares (PLS) analysis with a total of 294 data collected on users with experience in smartphone-based m-commerce. Findings The results show that first, utilitarian value is increased by the benefits, such as ubiquitous service, transaction speed, and price utility. However, LBS has no direct effect on utilitarian value. Second, the noteworthy finding is that ubiquitous service and LBS greatly increase transaction speed. Third, technology anxiety and cognitive effort considered as the cost dimension are negatively associated with utilitarian value but their impacts on it are non-significant. Finally, the results support the argument that utilitarian value is a determinant of continuance intention. Overall, the findings imply that utilitarian value greatly depends on the peception on benefits rather than the aspect of cost in smartphone-based m-commerce. Overall, the findings offer new insight into the studies of m-commerce by considering and verifying the impacts of its benefits and costs simultaneously.

Background: Positron emission tomography(PEFT) using fluorine-18 deoxyglucose(FDG), showing increased FDG uptake and retention in malignant cells, has been proven to be useful in differentiating malignant from benign tissues. We indertook the prospective study to compare the accuracy of the whole-body FDG PET with that of the conventional chest computed tomography(CT) for nodal staging of non-small-cell lung cancers(NSCLC). Material and Method: FDG PET and contrast enhanced CT were performed in 36 patients with potentially resectable NSCLC. Each Imaging study was evaluated independently, and nodal stations were localized according to the AJCC regional lymph nodes mapping system. Extensive lymph node dissection(1101 nodes) of ipsi- and contralateral mediastinal nodal stations was performed at thoracotomy and/or mediastinoscopy. Image findings were compared with the histopathologic staging results and were analyzed with the McNema test(p) and Kappa value(k). Result: The sensitivity, specificity, positive predictive value, and negative predictive value of CT for ipsilateral mediastinal nodal staging were 38%, 68%, 25%, 79%, and 61%, and those of PET were 88%, 71%, 47%, 95%, and 75%(p>0.05, K=0.29). When analyzed by individual nodal group(superior, aortopulmonary window, and inferior), the sensitivity, specificity, positive predictive value, and negative predictive value of CT were 27%, 82%, 22%, 85%, and 73%, and those of PET were 60%, 87%, 92%, and 82%(p<0.05, k=0.27). Conclusion: FDG PET in addition to CT appears to be superior to CT alone for mediastinal staging of non-small cell lung cancers.

In the area of fashion business, market segmentation strategy has been paid attention for the purpose of assigning proficiently marketing resources. The use of fashion information in purchase decision process can serve as a base for market segmentation strategies. The purpose of this study was to identify four segmented profiles which are labelled as Print-oriented, Audio-visual oriented, Store intensive, and Pal advice group. Objectives were to determine fashion interest, fashion attitude and apparel selection criteria from each segment. For this study, the questionnaire was adminisered to 261 teachers and data were analyzed by using ANOVA, Regression and Pearson's Correlations. The results were as follows. 1. Print-oriented group had a positive attitude about fashion and they tended to place value on aesthetic and other-oriented criteria in selecting apparel. 2. Audio-visual oriented group had a strongly positive attitude about fashion but they tended to be less active toward buying fashion products and place much more value on other-oriented criteria in selecting apparel. 3. Store intensive group tended to be active toward buying fashion products. They had a positive attitude about fashion and placed value on aesthetic criteria in selecting apparel. 4. Pal advice group had a less positive attitude about fashion and tended to place value on economical and practical criteria in selecting apparel. Based on the profile of the each segment, it was suggested to express lingual or non-lingual symbols and to create concepts for meeting the needs of the segment

최근 COVID-19 장기화 영향과 원자재 가격 급등으로 국내 대출금리가 가파르게 오르면서 빚으로 버티는 중소기업에 대한 우려가 커지고 있다. 또한, 높은 대출금리와 금융권의 대출심사 시 과도한 제출서류와 재무제표 위주의 심사로 인해 경영 환경에 힘든 중소기업의 대출은 거절되는 경우도 증가하고 있다. 따라서 중소기업의 자금조달과 투자 활성화 방안에 대한 논의가 필요하기에 본 연구는 중소기업의 ESG 제도의 활용을 통한 투자증진방안을 확인하였다. 본 연구의 목적은 비재무적 지표로 활용되는 ESG 평가지표의 활용이 중소기업의 기업가치를 예측하는 데 도움이 되며, 중소기업이 ESG 정보공시에 적극적으로 참여해야 하는 중요성을 제시하는 것이다. 본 연구는 자금조달이 중요한 중소기업의 ESG 도입과 실천의 필요성을 제언하며, 비재무적 지표의 활용이 기업가치를 예측하는 데 도움이 된다는 것을 실증적인 결과로 제시하였다. 연구결과, 중소기업의 ESG 성과와 기업가치는 정(+)의 관계를 가졌다. 중소기업의 ESG 부문별 등급과 기업가치는 모두 정(+)의 영향 관계를 맺는 것으로 볼 수 있다. ESG 종합등급은 기업가치에 긍정적 영향을 미치는 것으로 확인되었고 뿐만 아니라 ESG 환경, 사회, 지배구조 등급이 높은 중소기업일수록 기업가치를 높게 평가받는다는 것을 확인할 수 있었다. 연구결과에 따르면, 중소기업에게도 ESG 평가지표의 활용이 필요함을 제시하고, 중소기업의 성장을 도모하기 위해서는 중소기업의 기업가치를 재조명하는 방안을 연구하는 것이 필요함을 제언한다. 따라서, 본 연구는 중소기업의 ESG 경영과 기업가치의 관계에 대한 이해를 통해 중소기업의 ESG 경영 전략 수립 방안이 필요하다는 점과 ESG 정보공시를 위한 노력이 곧 중소기업의 정보 비대칭성을 해결하는 데 도움이 될 수 있음을 시사한다.
