In 2013, the small retailer organized support service, which commenced in 2009, has been expanding its place in the policy by transforming into a small retailer cooperating support service. This support service supports two main sides. One of them is strengthening the financial aspects of the scale by organizing the small retailers in order to make the distribution efficient. The second is improving the management and enhancing the efficiency through visitation education. This research focuses on studying the effects of the visitation education which is one of the two aspects of small retailers support service. Empirical analysis on the effects of the visitation education's quality on the loyalty of support service and business performance was performed in detail by dividing the structure of the companies into chain form and combined form of small retailers. According to the results of the analysis, the visitation education's quality positively affected the support service's loyalty without any restrictions on the structures of the retailers. However in the business performances, the visitation education's quality only showed positive effects on the combined form of small retailers. Therefore, it is implied that in order to continuously receive support program by increasing the loyalty of the retailers, the quality of the visitation education must be increased and the retailer support service need to be considering the structure of the companies in order to improve small retailer's business performance.

Recently, the LCD manufacturing industries try to maximize the productivity of LCD panels due to sharp increase in the market need of LCD display. Usually, the increase in manufacturing speed induces additional vibration of glasses and manufacturing machineries. This kind of vibration can induce bad effects on the manufacturing accuracy, and even can damage the glasses. The vibration signal of glass itself is very useful to predict the allowable maximum level of manufacturing speed. Therefore, it is necessary to measure the vibration of the glass itself and a very thin vibration measurement system attachable on the glass is needed. Since in some processes the glasses need to go through very thin gaps such as 2.5mm, We develop a glass vibration measurement system with the thickness of 1.3mm. The system measures the glass vibration using MEMS type accelerometers and store vibration data in a Nand-Flash memory. The performance of the develop system has been verified on a real LCD manufacturing line and the accuracy of vibration measurement is comparable with that of an accurate commercial vibration measurement system.

Because of the stagnancy of business activity and an excessive competition, the number of the people who quitting of one's business is increasing rapidly. Especially, government is further efforts on the upbringing for the small and micro business. But the ratio of cessation of business is increased gradually due to the influence of saturated market, consumer confidence shrinking, lack of funding and appearance of super supermarket. The another characteristic of growth rate for the cessation of business is the increase of the second foundation of business desire to succeed. But government's business transformation policy is inadequate. So, this study is willing to give an improvement of the government's support system through extraction actually and dependable data about business transformation and analysis to found a various gain model that continuous growth in small and micro business.

Recently, demands for high-performance flash-based storage devices (i.e., flash SSD) have rapidly grown in social network services, cloud computing, super-computing, and enterprise storage systems. The industry and academic communities made the NVMe specification for high-performance storage devices, and NVMe-based flash SSDs can be now obtained in the market. In this article, we evaluate performance of NoSQL databases that social network services and cloud computing services heavily adopt by using NVMe-based flash SSDs. To this end, we use NVMe SSD that Samsung Electronics recently developed, and the SSD used in this study has performance up to 3.5GB/s for sequential read/write operations. We use WiredTiger for NoSQL databases, and it is a default storage engine for MongoDB. Our experimental results show that log processing in NoSQL databases is a major overhead when high-performance NVMe-based flash SSDs are used. Furthermore, we optimize components of log processing and optimized WiredTiger show up to 15 times better performance than original WiredTiger.

In recent years, the construction of high-rise buildings are promoted. According to these, there are many needs about new technologies to strengthen the building performance and high-strength steel is regarded as one of these for promoting building performance. In Korea, high-strength steels which stress are over 600MPa are on market and in aborad, super high-strength steels over 1000MPa are developing and they expected to promote the building performance. But there are still doubts about applying high-strength steel members because of size effect and worry of brittle fracture. In this reports, we propose results of performance and analysis tests for use with general steel. We propose the characteristic of high-strength steels first and next the results of performance test to show they satisfy the performance that designers expect. And last, we compare the results of test and analysis for acquire the alanysis reliability in non-linear analysis with high-strength steels.

Polyketone fiber, a newly developed high strength fiber, has a tenacity and modulus similar to the paramid fiber, and can be used for reinforcing mechanical rubber goods(MRG), such as tires, hoses, and technical textiles. In addition, aliphatic polyketone, which has excellent strength, modulus, chemical stability and reasonable price, is being developed only in South Korea. It will be expected for replacement of super fiber such as aramids and increasing the technical textile market share. This paper surveys the mechanical properties of polyketone fiber yarn for technical textiles. For this purpose, two kinds of yarns are prepared, mechanical properties of coated and uncoated polyketone yarns such as tensile strength, elongation and modulus were examined before and after weather resistance test(temperature $60^{\circ}C$, humidity 60%, amount of power $0.67w/m^2$). The differences of mechanical properties between uncoated and coated yarns for high functional technical textiles and composite materials are estimated through this study.

Recently, China opened Yangshan port and provides a variety of benefits for shipping companies. Japan plans to reduce logistics costs and improve efficiency through the established 'super major ports' project. According to the 'hub and spokes' system, the number of direct calls toward North-Chinese ports are increasing. This changing environment has negative effects on the amount of transshipment cargos in Korean ports. In order to make a hub port of a domestic port, it is necessary to develop northeast Asian Feeder networks. Therefore, this paper analyzes the structure of northeast Asian feeder networks through the case study of European feeder networks strategy. Finally, we suggests the plans to reinforce feeder networks, which are strategic terminal operation, strategic alliances between shipping companies and port co-operation, for win-win strategy in the competitive northeast Asian market.
