Health industry, a knowledge based high value-added industry, is being considered as a strategic area for the 21C and many advanced countries are making every endeavors for the promotion of health industry along with information technology, new materials, and mechatronics. Korean health industry, however, has been excluded from the governmental supports as well as bound by strict regulation so far, and there is a significant gap in technology compared with advanced countries. In 21C, technology is the main factor of national competitiveness and that is why the role of R&D institutes are so important in the high level of competition to cope with the technology protection policies of advanced countries. In this article, with Directory of Korean R&D Institutes published by Korea Industry Technology Association, I reviewed the trends of R&D institute of health industry. Main findings of the research can be summarized as follows. The portion of health industry R&D institute is 3.6% of total R&D institute but the amount of R&D investment is over than 5% This means health industry are knowledge based and R&D intensified industry, meanwhile the variations of same industry R&D institutes of health industry is huge in R&D investments and other activities. Regional distributions of health industry institutes show some kind of different patterns in each industry areas. Medical devices and Medical informatics's preference of metropolitan region are distinguished with other industry areas. Many of the institutes are located in same site of it's company rather than operating separate building for R&D specific uses. It is better for transforming ideas to products and close cooperation of research body with product lines, but it is a handicap for networking and communicating with other research institutions too. It takes 18.4yrs for bearing R&D institute on the average. For a long times 'copy products' or 'me too products' policies were easy way to maintain business entities. But recently, it is recognized that research activities are essential component of sustaining it's own business firms. This means technology itself is leading power of corporation itself in the high level of competition.
As the trend shows that corporate investment for staff's welfare facilities has increased alongside employee's enhanced economic and conscious level which has resulted from economic growth and industrialization this study aims at analyzing interior design elements in staff's welfare facilites especially in cafeteria and suggesting new directions for designing those spaces. The method and scope of this study in firstly to described general points such as function and role of public food service and interior design elements in staff's cafeteria and then to grasp and analyze the present conditions of the staff's cafeteria for enterprises and financial organizations which has been built after 1990. The conclusion of his study can be summarized as follows : First it is desirable to locate employee's cafeteria on upper or top floor which has relatively good atmosphere. Second it is recommended to make overall atmosphere of employee's cafeteria impressive and in commercial restaurant. Third the separation of service circulation serveries and eating area is necessary. Fourth material for each parts should be easy to maintain and durable. Fifth more illuminance that the regulation is recommended and lighting fixture should be selected in terms of economics and maintenance. Sixth selecting bright and warm colors with partial application of accent colors is effective. Seventh furniture should be harmonized with the ambience of the space and required to be convenient and durable. Eighth to provide visual and auditory pleasure during eating it is desirable to equip the minimal A/V system. In addition diverse aspects such as improving employee's welfare caring for company the way of treating employee an boosting corporate images should be considered when designing staff's cafeteria and interior designer should be able to satis managerial aspects productivity and effectiveness as well as pursuing functional aesthetic facts.

Recently, virtualization has become an essential component of cloud computing due to its various strengths, including maximizing server resource utilization, easy-to-maintain software, and enhanced data protection. However, since virtualization allows sharing physical resources among the VMs, the system performance can be deteriorated due to device contentions. In this paper, we first investigate the I/O overhead based on the number of VMs on the same server platform and analyze the block I/O process of the KVM hypervisor. We also propose an in-memory block cache mechanism, called QBic, to overcome I/O virtualization latency. QBic is capable of monitoring the block I/O process of the hypervisor and stores the data with a high access frequency in the cache. As a result, QBic provides a fast response for VMs and reduces the I/O contention to physical devices. Finally, we present a performance measurement of QBic to verify its effectiveness.

Purpose: In general, orientals including Korean, have a mesocephalic face whereas Caucasians, among the western, have a dolichocephalic face. Unlike the western, in orientals including Korean, prominent malar bones are recognized as stubborn and unattractive appearance. That is why reduction malarplasty is one of the most popular aesthetic surgical procedure in Korea. Many surgical methods to reposition prominent malar bones have been performed by means of a coronal incision or a combined incisions, using both the intraoral and the external incision. Bicoronal approach has advantage such as wide operative field, easy to maintain symmetry and possibility of combining facial lift but has shortcoming, such as external scars, long operative time, and the possibility of facial nerve or artery injury. Intraoral approach has advantages of short operative time, simplicity of procedure and no external scar. But this approach is associated with problems of cheek drooping, limited exposure and difficulty in making symmetry. Methods: During 8 years, we performed a reduction malarplasty without internal fixation through an minimal intraoral incision and dissection in 39 patients. Results: The patients were followed for 46 months, with satisfactory results and no cheek drooping. There was no patient who want to revise the inappropriate operative result such as asymmetry and incomplete correction. Conclusion: We conclude that minimal intraoral incision and dissection could acquire satisfactory result of reduction malarplasty along with prevention of cheek drooping.
The aim of the research was to analyze programs, outcomes, promotion process, and operation methods of neighbourhood making to provide basic information for progressive improvement directions in the future. Buk-gu in Gwanju city, samdeok-dong in Daegu city and dongpirang in Tongyeong city were selected for a comparative analysis. The main bodies of neighbourhood making for promoting a local amenity were analysed for this research. The results indicated that a voluntary and continuous participation of residents was expected in the case of neighbourhood making led by the residents. However, a steady budget support from the outside was necessary for the continuous management and improvement of neighbourhood organization. For this, a voluntary agreement was required through the consultative group and committee formation. The member of civil organization has a limitation in the ability to develop and maintain continuos activities in the case of neighbourhood making led by a civil organization. This research found that operation methods including the constant checking, the search for new ideas through assessment of the resident's participation, local festivals for a community formation and real satisfactions of residents' desires were needed in the neighbourhood making led by a civil organization. A participation rate in neighbourhood making was low in the case of neighbourhood making led by administrative bodies. This result indicated that the long-term strategics for space renewal and community revitalization were important. Various easy ways of residents' participation to reflect their interests and operation systems were also needed. Finally, current local issues, active residents' participation and residents' opinions would be included in the process of neighbour making in the future.

The present study examined the 3 dimensional space distribution characteristics of sea water intrusion using data available from previous observations. For this study, we used 3D FEMWATER, which is a 3 dimensional finite element model. The target area was around Daechang-ri, Gimje-si, Jeollabuk-do. The area is relatively easy to formulate a conceptual model and has observation wells in operation for surveying sea water intrusion. Considering the uncertainty of numerical simulation, we analyzed sensitivity to hydraulic conductivity, which has a relatively higher effect. According to the result of the analysis, the variation of TDS concentration had an error range of $-1,336{\~}+107 mg/{\iota}$. Taking note that the survey data from observation wells were collected when the boundary between fresh water and sea water in the aquifer was in equilibrium, we set the range of time for numerical simulation and estimated the spatial distribution of TDS concentration as the range of sea water intrusion. According to the result of estimation, the spatial distribution of TDS concentration calculated when 1,440 days were simulated was taken as the range of sea water intrusion. Using the result of calculation, we can draw not only vertical views for a certain section but also horizontal views of different depth. These views will be greatly helpful in understanding the spatial distribution of the range of sea water intrusion. In addition, the result of this study can be used rationally in proposing an optimal quantity of water pumping through investigating the moving route of sea water intrusion over time in order to prevent excessive water pumping and to maintain an optimal number of water pumping wells per interval.

Fibroblasts of large animals are easy to isolate and to maintain in vitro culture. Thus, these cells are extensively applied to donor cell for somatic cell nuclear transfer, and to substrate cells to generate induced pluripotent stem cells after transfection of requited genes to be essentially required for direct reprogramming. However, limited mitotic activity of fibroblasts to differentiate along a terminal lineage becomes restrictive for their versatile application. Recently, commercial culture medium and systems developed for primary cells are provided by manufactures. In this study, we examined whether one of the systems developed for primary fibroblasts of human are effective on porcine ear skin fibroblasts. To this end, we performed proliferation assay after five days culture in vitro of porcine fibroblasts in medium DMEM, which is generally used for fibroblasts culture, and medium M106 for human dermal fibroblasts, supplemented with various concentrations of FBS and LSGS contained mainly growth factors, respectively. Consequence was that presence of 15% FBS and 0.1 ${\times}$ concentrations of LSGS in DMEM showed most active proliferation of porcine fibroblasts.
Men should be able to do whatever they want to and want to safely protected at home which is special domain for them. The disabled live mentally uncomfortable lives at home which should be a place where they should be comfortable and convenient. Renovation projects started in Incheon since 2009 by commencing renovation projects for the disabled by the government and welfare centers. Since the project is a program supported by the government or welfare centers thus priority on renovation was decided and carried out by in-depth interview to decide areas to renovate because of limited budgets. This paper is aimed to propose plans for renovating homes according to priority for renovation for dwellers when renovating homes for the disabled with limited budgets. Renovating home for the disabled can be broadly divided into physical, environmental, esthetic renovations, and physical renovation is a basic renovation for daily lives without restrictions in living and include easy movements, accesses to each rooms and adequacy of movement, easily accesses related with easily accessible distance and height, safety to prevent accidents caused by physical inabilities. Environmental renovation is general supports becoming the base of daily living and include control for controlling lighting, heating, air quality for comfortable environments in living space and pleasantness to maintain bright and pleasant interior with sufficient light. Esthetic renovation includes expression of identity by expressing image of one self and visual effects or spatial consideration for hobbies to enjoy comfortable and rich lives.
Software change is an essential operation for software evolution. To maintain the system competently, managers as well as developers must be able to understand the structure of the system but the structure of software is hidden to the developers and managers who need to change it. In this paper, we present a system (OntCIA) for supporting change impact analysis for rating and billing domain based on the semantic web technology. The basic idea of OntCIA is to build a domain knowledge base using an OWL ontology and RDF to implement change impact analysis system that would support the managers and software developers in finding out information about structure of large software system. OntCIA allows users to incrementally build an ontology in rating and billing domain and provides useful information in response to user queries concerning the code, such as, for example 'Find the modules which have a role for confirming new subscription'. The strengths of OntCIA are its architecture for easy maintenance as well as semantic indexing by automatic reasoning.
Web crawler should maintain fresh data with minimum server overhead for large amount of data in the web sites. The overhead in the server increases rapidly as the amount of data is exploding as in the big data era. The amount of web information is increasing rapidly with advanced wireless networks and emergence of diverse smart devices. Furthermore, the information is continuously being produced and updated in anywhere and anytime by means of easy web platforms, and smart devices. Now, it is becoming a hot issue how frequently updated web data has to be refreshed in data collection and integration. In this paper, we propose dynamic web-data crawling methods, which include sensitive checking of web site changes, and dynamic retrieving of web pages from target web sites based on historical update patterns. Furthermore, we implemented a Java-based web crawling application and compared efficiency between conventional static approaches and our dynamic one. Our experiment results showed 46.2% overhead benefits with more fresh data compared to the static crawling methods.
