Nowadays, many commercial ERP products, such as Oracle, SAP, and Baan, etc, are designed based on large-scaled companies. It is difficult for small and medium-size companies with weakness in budgets and resources(e.g., human, organization, technique, and so on) to use them as it was. So, new ERP system need to be provided for small and medium-size companies. In this paper, we model and provide a conceptual ERP model for small and medium-size companies by using "4＋1 View" architecture model of Unified Modeling Language(UML). The conceptual ERP model consists of five subsystems： Manufacturing, Sales, HumanResource and Payroll, Accounting, and Trading. Especially, we describe the conceptual ERP model focusing on "Manufacturing" subsystem by using several diagrams of UML. By using the conceptual ERP model, the ERP system′s developers of small and medium-size companies can obtain many benefits： improving the efficiency of software developing process and helping user requirements gathering and description of ERP system′s nonfunctional aspect as well as functional aspect.

Based on the perspective of international trade and cross-border e-commerce development, this paper explores the impact of cross-border e-commerce on international trade. This paper first describes the current situation of China's cross-border e-commerce and proposes a theoretical model of the influence of China's cross-border e-commerce on its international trade based on the research and summary of a large number of relevant documents. This paper establishes an extended gravity model based on the proposed theoretical model. Relevant data of 13 trading partner countries were used as sample data, and OLS regression analysis and heterogeneity analysis were conducted on gravity model by using Eviews 11.0. Then, in order to study the influence of each variable on import and export trade volume, import and export trade volume were respectively taken as explained variables and further studied by OLS regression analysis. To test the robustness of the model, the empirical analysis results show that cross-border e-commerce does promote the volume of China's international trade.

The study investigates herding behavior in cryptocurrencies in different situations. This study employs daily returns of major cryptocurrencies listed in CCI30 index and sub-major cryptocurrencies and major stock returns listed in Dow-Jones Industrial Average Index, from 2015 to 2018. Quantile regression method is employed to test the herding effect in market asymmetries, inter-dependency and intra-dependency cases. Findings confirm the presence of herding in cryptocurrency in upper quantiles in bullish and high volatility periods because of overexcitement among investors, which lead to high volume trading. Major cryptocurrencies cause herding in sub-major cryptocurrencies, but it is a unidirectional relation. However, no intra-dependency effect among cryptocurrencies and equity market is observed. Results indicate that in the CKK model herding exists at upper quantile in market that may be due when the market is moving fast, continuously trading, and bullish trend are prevailing. Further analysis confirms this narrative as, at upper quantile, the beta of bullish regime is negative and significant, meaning the main source of market herding is a bullish trend in investment, which increases market turbulence and gives investors opportunity to herd. Also, we found that herding in cryptocurrencies exits in high volatility periods, but this herding mostly depends on market activity, not market movement.

This study mainly measures the level of trade facilitation in member countries along the "the Belt and Road" and discusses the impact of trade facilitation on bilateral trade. Based on the research results of domestic and foreign scholars, this study made a new systematic measuring system which covering 4 indicators and 15 subordinate indicators, to obtain the trade facilitation index. Based on the extended gravity model, this paper conducts a panel data, for more than 50 major trading members along the "the Belt and Road" during 2010~2017 as an example to empirically study the relationship between the trade facilitation level of major trading members and the volume of China's import and export trade. The results show that the level of trade facilitation among member countries is not high and the trade facilitation variable has positive value, indicating that the trade facilitation variable has positive effect on increasing bilateral trade. If the trade facilitation increases by 1% respectively, the bilateral trade level will increase by 0.98% separately. Finally, according to the regression results of four aspects of the trade facilitation index system, e-business development plays the most significant role in promoting trade facilitation.

In 2010, the United Nations Commission on International Trade Law (UNCITRAL) initiated work on the settlement of disputes in international e-commerce through online dispute resolution (ODR). The basic goal is to use ODR to resolve disputes with low value but high volume in international e-commerce. The background is that consumers have no way to solve their legal problems in this area. An ODR system is intended to create a new way to enforce their rights. However, the legal situations of the countries in the e-commerce sector, particularly in consumer protection, are very diverse. Thus, no reasonable model for conflict resolution is available. Some countries consider this as public policy and want absolute protection of their consumers. Other countries want to encourage freer e-commerce trading. This diversity of consumer protection policy is an obstacle to ODR. However, sooner or later, reaching an agreement is feasible because each representative is making a reasonable effort to reach the goal.

정보기술의 발전은 비즈니스 환경을 변화시켜왔고, 이러한 변화는 공급사슬 내의 거래 당사자들 간의 비즈니스프로세스 변화에도 영향을 주었다. 이러한 변화에 대한 최근의 경향은 파트너들 간의 긴밀한 유대관계를 강조하고 있다. 하지만 이는 정보를 교환하거나 의사결정을 내리는 데에 있어 업무 담당자의 참여를 필요로 하여 의사소통의 시간적 단절을 유발하고, 실시간 내의 정보수집 및 의사결정을 불가능하게 만드는 문제를 안고 있다. 이러한 문제를 해 결하기 위해, 거래 기업간의 응용 프로그램의 자동 의사소통을 바탕으로 한 자동통합이라는 새로운 개념이 도입되고 있으며, 이러한 개념은 미래형 공급사슬 환경의 방향이 될 것이다. 본 연구에서는 자동 통합 환경과 이 환경 하에서의 공급사슬계획을 위한 비즈니스 프로세스 모델을 소개하고, 이러한 공급사슬계획의 효율적인 수립을 위하여 협상과정을 분석하여 협상 패턴을 제시하였으며, 제시된 협상 패턴을 비즈니스 시나리오에 통합시킴으로써 통합된 공급사슬계획에서 협상을 위한 비즈니스 프로세스 모델을 제시하였다.

PET fabrics of various luster, fiber thickness(denier), and weaving structure were dyed at the same conditions and determined their grey scale by using naked eyes, computer color matching (CCM) system, and real industry color (RIC) device to evaluate the effectiveness of RIC device developed in this study. As for the luster of fabrics, bright PET showed more differences when compared with semi-dull and full-dull. PET in both naked eyes and RIC device since the RIC device provide the real image of fabrics to observers. As for the fiber thickness, the results of naked eyes and RIC device were very similar while the result of CCM showed lower color grade. Finally, as for the weaving structures of PET fabrics, all the test results by naked eyes, CCM, and RIC device showed almost same grey scales. In these regards, the RIC device developed in this study was comparable to naked eyes by providing the real image of fabrics, however it was difficult to compare the very bright colors such as yellow and fiber thickness(denier) and weaving structure of fabrics.

E-sports에서 가장 흥행한 작품이라 볼 수 있는 스타크래프트, LOL과 같은 게임들을 포함하여 RTS 장르의 대부분의 게임들의 플레이 방식이 점점 획일화되어 지루함을 주기 시작하였다. 획일화되고 지루한 시스템 속에서 좀 더 변화를 주기 위해선 지금 충분히 발전하고 검증된 장르간의 조합을 통해 해소할 수 있다고 생각되어 새로운 게임 패러다임을 제시하고자 했다. 이를 위해 흥행한 게임 장르 중 RTS와 TCG라는 장르에 주목하여 이 두 장르의 동적인 특징과 정적인 특징을 융합해 새로운 패러다임을 제시하자 한다. 본 논문에서 제안하는 새로운 RTTC(Real-Time Trading Card) 장르의 게임 시스템은 게임의 동적 요소와 정적 요소를 퓨전한 새로운 형태의 게임 시스템을 말한다. 이 혼합된 장르는 실시간 대전이라는 RTS의 특징에 카드라는 랜덤성을 추가하면서 게임의 획일성을 최소화하여 게임을 하는 사람과 게임을 보는 사람 모두를 만족시킬 수 있는 게임의 새로운 패러다임이 될 수 있다.

The antagonistic activity of probiotic strains (Bifidobacterium animalis BB-12, Bifidobacterium bifidum A, Bifidobacterium longum B6, Lactobacillus acidophilus ADH, Lactobacillus paracasei ATCC 25598, and Lactobacillus rhamnosus GG) against nalidixic acid resistant ($NA^R$) Escherichia coli O157:H7 MF1847, E. coli O157:H7 H2439, E. coli O157:H7 ATCC 43894, and E. coli O157:H7 C7927 was investigated using the agar-overlay, well diffusion, and broth culture tests. L. paracasei ATCC 25598 was the most effective probiotic strain in terms of in vitro antagonistic activity against $NA^R$ E. coli O157:H7, followed by L. rhamnosus GG, B. longum B6, and L. acidophilus ADH. The use of selected probiotic strains could be an effective pre-harvest intervention strategy to reduce the risk of $NA^R$ E. coli O157:H7 by maintaining a balanced microflora in animals and might provide many potential benefits in lieu of using antimicrobials.
