The aim of this study was to know the current management status in Korean medical clinics (KMC) and the awareness of Korean medicine doctor. The simple random extraction method from the membership list of 'The Association of Korean Medicine' in 2010 was used for survey. The questionnaire which had used in 2008 was revised, and those were sent to each KMC by mail. A total of 107 data were acquired and frequency analysis was conducted. The result showed that the annual average employees working in each KMC was 2.9 persons and the number of daily outpatient was 33.8 person in 2010. The proportion of sales covered by medical insurance at KMC has been increasing annually as 42.9%, 43.5%, and 44.8% of total sales, whereas the uninsured sales was 57.1%, 56.5%, and 55.2% of total sales in 2008, 2009, and 2010 respectively. All of the responders recognized that the current situation of Korean medical service market was not good and the reason was mainly resulted from undeveloped medical technique, popularized use of functional foods for health and alternative medical care by Western medicine. To expand Korean medical service, the expansion of sales covered by public health medical insurance, government support and advertizement for public relation were needed.

Small BAseline Subset (SBAS) technique using multi master interferograms can be effective to detect surface deformation in forest area. In this paper, The analysis reveals area of 2-dimension surface deformation at Seguam Island in Aleutian Arc., Alaska. We acquired ERS-1/2 data from track 201 and 473 datasets on Seguam Island from 1992 to 2008. This study analyze surface deformation applying Differential Interferometry Synthetic Aperture Radar (DInSAR) and SBAS time series method using two adjacent tracks. As a results, it was calculated that subsidence -1~2 cm in LOS direction and - 2~3 cm in vertical direction. The horizontal direction was repeated contraction and expansion. The observation of 2-dimension displacements explained the volcanic activity on Seguam island. Also, it is believed to be used for basic data to estimate movements of magma source.

This paper is concerned with the analysis of plastic deformation of bimetal co-extrusion process. Two sets of material combination have been adopted for analysis, i.e. combinations of Cu/Al and Fe/Al. In the first set of material combination, the selected materials are AA 1100 aluminum alloy as hard material and CDA 110 as soft one. This type of material selection is to examine the effect of hard core and soft sleeve and vice versa on the deformation pattern in terms of plastic zone and velocity discontinuity along the contact surface between construction materials. Four different cases of co-extrusion process in terms of material combination and interference bonding were simulated to investigate the effect of material arrangement between core and sleeve, and of bonding on the plastic zones and velocity discontinuity. In the other set of material combination, model materials used as core and sleeve were AA 1100 and AISI 1010, which are relatively soft and hard, respectively. Process parameters except diameter ratio of core to sleeve material such as semi-die angle, reduction in area in global sense and die comer radius have been set constant throughout the simulation to concentrate our effort on the analysis of influence of diameter ratio on deformation behavior such as deformation zone, surface expansion, exit velocity discontinuity between composite materials, and extrusion forces.

With the recent expansion of internet shopping mall, the importance of intelligent products recommendation agents has been increasing. for the products recommendation, This paper propose case-based reasoning approach, and developed a case-based bundle products recommendation system which can recommend a set of sea food used in family events. To apply CBR approach to the bundle products recommendation, it requires the following 4R steps : \circled1 Retrieval, \circled2 Reuse, \circled3 Revise, \circled4 Retain. To retrieve similar cases from the case-base efficiently, case representation scheme is most important. This paper used OW(Object Modeling Technique) to represent bundle products recommendation cases, and developed a similarity measure method to search similar cases. To measure similarity, we used weight-sum approach basically. Especially This paper propose the meaning and uses of taxonomies for representing case features.

Techniques to evaluate gene expression profiling, such as sufficiently sensitive cDNA microarrays or real-time quantitative PCR, are efficient methods for monitoring human pluripotent stem cell (hESC/iPSC) cultures. However, most of these high-throughput tests have a limited use due to high cost, extended turn-around time, and the involvement of highly specialized technical expertise. Hence, there is an urgency of rapid, cost-effective, robust, yet sensitive method development for routine screening of hESCs/hiPSCs. A critical requirement in hESC/hiPSC cultures is to maintain a uniform undifferentiated state and to determine their differentiation capacity by showing the expression of gene markers representing all three germ layers, including ectoderm, mesoderm, and endoderm. To quantify the modulation of gene expression in hESCs/hiPSC during their propagation, expansion, and differentiation via embryoid body (EB) formation, we developed a simple, rapid, inexpensive, and definitive multimarker, semiquantitative multiplex RT-PCR platform technology. Among the 9 gene primers tested, 5 were pluripotent markers comprising set 1, and 3 lineage-specific markers were combined as set 2, respectively. We found that these 2 sets were not only effective in determining the relative differentiation in hESCs/hiPSCs, but were easily reproducible. In this study, we used the hES/hiPS cell lines to standardize the technique. This multiplex RT-PCR assay is flexible and, by selecting appropriate reporter genes, can be designed for characterization of different hESC/hiPSC lines during routine maintenance and directed differentiation.

The focuses and methods in Library science have been changed abreast with the development af library facilities and with the expansion and diversification of its functions. One of current trends in Library science is focussed on the social functions of library: its relations to the public, effective service for the users. and efficieniencies of the management policies, and so. on. To. deal with these issues, we need to borrow methodology from other disciplines such as management, marketing, statistics, etc. This paper is mainly concerned with how we approach to the measurement af services and thus provide tentative standard for evaluating library services. To do. this work properly, we'd better consider the users' needs and expectations. But it is not an easy work since too many factors are involved in the study of the users' needs. Users' needs and expectations are so. varying that it is difficult to find out some general and objective data. That is the reason why although many scholars have urged time after time the necessity of library's effectiveness measurement, few studies demonstrated substantial method for measuring the effectiveness of service. In this paper I propose a device for measuring service: i. e, Conjoint Analysis. Conjoint Analysis, which has originally been developed and applied in marketing research, is used to measure the priorities and preferences of purchasers on the new item. So far as Conjoint Analysis, concerning users' physical and psychological necessities, can numeralize people's needs, it may also be applied to measure service provided by nonprofit organization like library. If this approach prove to be sucessful, I hope this study to make any contribution to the appropriate direction on improving library facilities based on the result from a concret reference evaluation.

Due to the recent changes in residential value, user needs for various spaces in residential space are increasing. However, it is not easy to change and reconstruct the first residential form according to the needs of the user due to the characteristics of the residential space where movement and deformation are difficult. Therefore, this study aims to derive a plan to meet user needs according to changing residential value by using fully autonomous vehicles with a concept of space that can be moved. First, the existing residential space was classified through literature research, and based on this, the space type of the fully autonomous vehicle for the residential was derived through user research. Then, through the survey method and statistical analysis, user needs analysis for residential space, usefulness analysis of derived space type and type specification were carried out. Finally, based on the results of the study, the design direction of the fully autonomous vehicle for residential purpose was presented. Based on the user's perception, it is meaningful that it categorizes the space of the fully autonomous vehicle for residential purposes and suggests the design direction.

Recently, it appears several counterproposals about desirable figures of urban architecture. All of them proposes 'publicity' with cohernt tendency. The reason why it concentrates quantitative expansion of city without united design by urban plannar is that neglect quality values of city. As a solution of poor environment, there cue out the various efforts, about problem of each building, problem of city space, problem of laws and so forth. The reason why necessity of public space was embossed in that architecture extend the activity of citizen and make up the city space. But, each building pursues the private interest, so it is difficult to secure a public space with a high hand. Thus, architecture law has been revised in 1991 and bring the system of open space to match up the publicity and the private interest. Actually, western country brought it and obtained excellent results. While quantity of open space have increased since 1991, a lot of problems revealed in real usage and quality. By means of problem's solution, this study focus on the diversion of recognition for necessity of various open space. In result, on the occasion of approach and openess, except for several building, most glass a facade and the pedestrian can approach easily. Moreover, office buildings near the subway station connected with their low floor. So, the office buildings give openess to pedestrian and a people can approach easily to the buildings. On the occasion of amenity, most have bank and lobby on the first floor and have facilities on the underground floor. It leave open. But the reason why they have bank and lobby is that the space is dry and boring(without elements of nature and rest space). Hence, to make a space full of vitality, it have to plan various design elements and facilities. First of all, plan of indoor public space have to make up facility for the public interest. This study is basic investigation for necessity of indoor public space and through the survey of office buildings, it analyze the character of plan and find out the method of publicity's realization.
