A facility is built by participating of various parties who are connecting each other by network of contract. Domestic construction industry has been suffering with high cost and low efficiency due to lack of cooperative relationship among companies who participated in the project. The government has tried to resolve this problem by diverse policy support, but practical result has not been realized in the level of satisfaction. This paper defined construction business ecosystem in the aspect of business ecosystem as a network among construction companies based on diverse production system, and diagnosed cooperative business ecosystem in construction industry. For construction business ecosystem to be more cooperative business ecosystem, the result of diagnosis shows that the type of cooperation based capacity and value sharing should be developed and interdependence among companies and cooperative relationship should be durable and reasonable price for construction should be guaranteed for the participant to have a profit from the project.

In ubiquitous environments, invisible devices and software are connected to one another to provide convenient services to users. In order to provide such services, we must have mobile devices that connect users and services. But such services are usually limited to those served on a single mobile device. To resolve the resource limitation problem of mobile devices, a nearby resource sharing research has been studied. Also, not only the nearby resource share but also a resource recommendation through context-based resource reasoning has been studied such as an UMO Project. The UMO Project share and manage the various context information for the personalization resource recommendation and reason based on current context information. Also, should verify resource inference rules for reliable the resource recommendation. But, to create various context information requires huge cost and time in actuality. Thus, we propose a inference verification tool called USim to resolve problem. The proposed inference verification tool provides convenient graphic user interfaces and it easily creates context information. The USim exactly verifies new inference rules through dynamic changes of context information.

Banks traditionally focus on the financial services against the uncertain future liquidity needs, i.e. saving as well as lending. As the business model of banks has been shifted from the originate to hold model to the originate to distribute model since the enactment of Gramm-Leach-Bliley Financial Services Modernization Act in 1999, the financial services encompass information gathering and generating, underwriting and risk sharing through packaging claims for the investors, in addition to the payment and settlement services. Ensued are the financial market integration and diversification of financial services, with which the accessibility to financial services is arguably significantly enhanced. Such integration and diversification necessarily entails the risk of contagion due to the non-fulfilling service over the several other financial services, which would be contained easily under the separate financial services. This paper addresses the pricing of fees for the integrated financial services through which the contagion could spread when the users of financial service are not immune to the failure to fulfill their obligation due to the economic turmoil. Consequently the information asymmetry about the clients is unavoidable. Higher fees could drive out the otherwise good clients out of the pool of customers for the financial services. Then, the risk could be exacerbated due to the proliferation of bad clients who are vulnerable to the financial distress and liquidity crunch. So the banks should take into account the interactional effect of the fees between/among the non interest based activities and interest based activities under the information asymmetry. Contrary to our general perception, the current analysis demonstrates that the bank should focus on the reduction of cost associated with good clients rather than that of bad clients.

This study was conducted to examine the awareness and demands of parents and teachers on the use of IoT healthcare devices at daycare centers. A survey was conducted on 200 teachers and 200 parents. Collected data were analyzed by Frequency analysis, t-test, 𝑥2, using the SPSS WIN 22.0. The results of this study are as follows. First, teachers showed a higher level of preference for using IoT healthcare devices as they showed positive perception and support compared to parents, and showed higher recognition of information leakage than parents. Second, teachers and parents were most hoping to use IoT healthcare devices at emergency response in daycare-centers and had the highest demands for wearable devices. As a result of the both parents and teachers demand cost-sharing. Based on the results of this study, the possibility of utilizing IoT healthcare devices in daycare centers were discussed.

The efficacy of plant breeding has been enhanced by application of molecular markers in population screening and selection. Pepper (Capsicum annuum L.) is a major staple crop that is economically important with worldwide distribution. It is valued for its spicy taste and medicinal effect. The aim of this study was to discover single nucleotide polymorphisms (SNPs), microsatellite markers information, and percentage sharing through orthologous analysis of pepper-specific pungency-related genes. Here, we report the results of transcriptome analysis and microsatellite markers for four pepper varieties that possess a pungency-related gene. Orthologous analyses was performed to identify species-specific pungency-related genes in pepper, Arabidopsis thaliana L., potato (Solanum tuberosum L.), and tomato (Solanum lycopersicum L.). Advancements in next-generation sequencing technologies enabled us to quickly and cost-effectively assemble and characterize genes to select molecular markers in various organisms, including pepper. We identified a total of 9762, 7302, 8596, and 6886 SNPs for the four pepper cultivars Blackcluster, Mandarine, Saengryeg 211, and Saengryeg 213, respectively. We used 454 GS-FLX pyrosequencing to identify microsatellite markers and tri-nucleotide repeats (54.4%), the most common repeats, followed by di-, hexa-, tetra-, and penta-nucleotide repeats. A total of 5156 (15.9%) pepper-specific pungency-related genes were discovered as a result of orthologous analysis.

In order to strengthen assurance of National Health Insurance, co-payment should be reduced. This can happen with collaborative efforts of patients, medical institutes, and government altogether at the same time. This research applied Dutton(1986)'s medical service research model with high R-square, and analyzed 2008 Korea Health Panel Data (Beta Version 1), that was examined by Korea Institute for Health and Social Affairs and National Health Insurance, in order to figure out influential variables on co-payment. In result of Multiple Linear Regression Analysis, R-square was 46.7%, the older the age, the patients who had surgery, the longer days of hospital treatment are, the higher gross income of a household is, the more hospitalized in upper grade general hospitals, and the more upper grade rooms and selecting a doctor are used. The results have statistical significance. When conducting research applying medical service research model, there is a need to apply Dutton(1986)'s medical service research model with high R-square. In order to strengthen assurance of National Health Insurance, first conditions should be that patients are hospitalized in upper grade general hospital, and at the same time, are patients who had surgery with long stay of hospitalization. In addition, if proven that patients used upper grade rooms and selecting a doctor due to lack of regular treatment and rooms, for certain number of days of such hospitalization, it is suggested to be provided with health care insurance in upper grade rooms and selecting a doctor in calculating co-payment limit.

The domestic fashion industry is not able to exceed the level of fashion that exists in advanced countries due to the relatively weak design competitiveness and the differentiated capability of product development. In order for the domestic fashion industry to become a growth industry that is valued in the world market of infinite competition, a step-by-step support system that can demonstrate and maintain the creative ability of designers is needed. Therefore, this study proposes a template - based 3D virtual fashion technology and a digital fashion platform based on it. The proposed template - based 3D virtual fashion technology is designed to clearly communicate the intention of designers and to be able to instantaneously view the results, thereby reducing the time and cost of producing prototypes. In addition, the digital fashion platform based on the template is designed as a collaborative platform based on idea sharing, which dramatically improves the process of confirming the prototype and initiating the product planning and manufacturing stages. This new technology can contributes to the formation of a business environment and a new area within the existing fashion industry and can be utilized for the development of the fashion industry in the future.

BIM(Building Information Modeling) technologies are the most effective for the maintenance of infrastructures because they provide information sharing througout the life-cycle of structures and support close communication between different project stages. Systematic and well-organized data play a fundamental role for the effective maintenance of subway tunnel. In this paper, 3D information models for maintenance of BIM-based subway tunnel structures are developed. Standard classifications for the maintenance and construction information classification system were adopted. A classification system based on construction information classification system was built considering procedures of maintenance work. It provides optimization and standardization of the work flow for the maintenance of subway structures by applying information modeling processes instead of the current maintenance practices. It can effectively reduces the life cycle cost and time for the maintenance. The proposed system can be utilized for the maintenance history management to enhance current maintenance system.
