As recently too many local museums have been built in the whole country, most of them cannot attract enough spectators. In order to resolve this problem, it is needed for local museums to differentiate their spaces and programs related to their exhibition. Thus, the purpose of this study was to analyze the characteristics of spaces and programs of local museums from the perspective of spatial marketing to activate them, and contribute to development of local cultures. This study targeted historical public museums located in Seoul and Incheon. Through preceding research, an analysis frame was established based on the keywords related to spatial marketing, and then the characteristics of spaces and programs of local museums were analyzed based on the frame. The study results are as follows. 1) Access convenience refers to openness that public museums located in Seoul and Incheon can embrace accessible locations, points of interest, and convenient facilities easily recognized by pedestrians. 2) Symbolic formativeness is to express symbolic historical contents in the museum lobby or exhibition to show the identity of local museums. 3) Visibility is needed for direct guidance signs or spaces to let spectators know directions and locations. 4) Public concern is for spectators and local residents to participate in local museums to share and utilize their partial spaces. 5) Interactivity is to induce activation of local museums by utilizing experience exhibition contents and having spectators directly contact exhibits. 6) Interest is related to cultural festival programs of exhibition to arouse spectators' and local residents' curiosity. 7) Participation is to activate spaces and spectators by providing educational programs. 8) Usefulness is to induce spectators' interest in local museums by providing historical, social, and cultural information. These results are expected to be used as baseline data to suggest a new direction for activation of local museums from the perspective of spatial marketing.

Because of efficient space utilization and fast key search times, B-trees have been widely accepted for the use of indexes in HDD-based DBMSs. However, when the B-ree is stored in flash memory, its costly operations of node updates may impair the performance of a DBMS. This is because the random updates in B-tree's leaf nodes could tremendously enlarge I/O costs for the garbage collecting actions of flash storage. To solve the problem, we make all the parents of leaf nodes the virtual nodes, which are not stored physically. Rather than, those nodes are dynamically generated and buffered by referring to their child nodes, at their access times during key searching. By performing node updates and tree reconstruction within a single flash block, our proposed B-tree can reduce the I/O costs for garbage collection and update operations in flash. Moreover, our scheme provides the better performance of key searches, compared with earlier flash-based B-trees. Through a mathematical performance model, we verify the performance advantages of the proposed flash B-tree.

Objectives: This study examines that the compatibilities between the health promotion programs in community health center and the leading health indicators in National Health Plan. Methods: We analyzed health promotion programs associated with three health indicators; smoking(smoking rate in male), alcohol use(alcohol use rate in adults), obesity(obesity rate) in twenty five community health centers in Seoul. First, we classified three groups(excellent, fair and poor groups) using average scores of Seoul, that of Korea and National Health Plan2010 goals in three health indicators. Afterwards, we examined the compatibility between contents of health promotion programs regarding leading health indicators and the specific program activities. Results: The compatibility levels between health indicators and contents of health promotion programs was 80 % for smoking among fair and poor groups while fair and poor for smoking reported 60% and 70%, respectively. For obesity, excellent group reported 80% and fair group had 91%. Conclusion: In conclusion, although all districts were able to access available data for health indicators and health statistics every year, it seems that they did not only utilize these data enough in conjunction with health promotion programs but also did not integrate specific activities according to National Health Plan systematically.

This paper proposes the two algorithms which generate a minimal decision rule and approximate inference operation, adapted the rough set and the factor space theory in fuzzy knowledge base. The generation of the minimal decision rule is executed by the data classification technique and reduct applying the correlation analysis and the Bayesian theorem related attribute factors. To retrieve the specific object, this paper proposes the approximate inference method defining the membership function and the combination operation of t-norm in the minimal knowledge base composed of decision rule. We compare the suggested algorithms with the other retrieval theories such as possibility theory, factor space theory, Max-Min, Max-product and Max-average composition operations through the simulation generating the object numbers and the attribute values randomly as the memory size grows. With the result of the comparison, we prove that the suggested algorithm technique is faster than the previous ones to retrieve the object in access time.

This research tries to interpret Montage der Assoziation shown in animations. Eisenstein's 'Montage' is "Montage der Assoziation" where a variety of Montage pieces are combined, symbolizing one aggregate image. Though influenced by Russian Formalist Film Theory and Kuleshov, Pudivkin and Rudolf Amheim, by contraries, he recognized Montage as an issue between an artist and the audience and an anti-representation apparatus. Especially, he developed the mind action issue previously advocated by Eikhenbaum and deemed the audience's role an essential part in completing a film. Montage expression implied in Eisenstein's theory can be regarded as attraction, collision, and dynamic and intellectual Montage. However, with an in-depth approach, Montage der Assoziation can be interpreted by repetitive, relative and juxtaposed analysis. The reason is that animation Montage is a visual action which takes place in a row among scenes and in the frame. This research addresses communications with the audience which are attained by Montage der Assoziation. In other words, this research makes an in-depth access to how Montage der Assoziation appears and communicates with the audience in an animation work.

IEEE 802.11n is an ongoing next-generation WLAN(Wireless Local Area Network) standard that supports a very high-speed connection with more than 100Mb/s data throughput measured at the MAC(Medium Access Control) layer. Study trends of IEEE 802.11n show two aspects, enhanced data throughput using aggregation among packets in MAC layer, and better data rates adapting MIMO(Multiple-Input Multiple-Output) in PHY(Physical) layer. But, the former doesn't consider wireless channel and the latter doesn't consider aggregation among packets for reality. Therefore, this paper analyzes data throughput for IEEE 802.11n considering MAC and PHY connection. A-MPDU(Aggregation-MAC Protocol Data Unit) and A-MSDU(Aggregation-MAC Service Unit) is adapted considering multi-service in MAC layer, WLAN MIMO TGn channel using SVD(Singular Value Decomposition) is adapted considering MIMO and wireless channel in PHY layer. Consequently, Simulation results shows throughput between A-MPDU and A-MSDU. Also, We use Ns-2(Network simulator-2) for reality.

Ion exchange strengthening is a chemical process whereby large alkali ions(such as potassium) are substituted for smaller ions(sodium) within the surfaces of glasses and ceramics, thereby reducing the thermal expansion coefficient of this surface region, and creating beneficial state of compressive stress within the near surface region. The purpose of this study was to determine the effects of ion exchange and etching treatments on the strength of some dental porcelains. Two feldspathic dental porcelains(Vitadur-N, G-Cera) were used in this study. A commercial ion exchange paste and etching gel containing 8% hydrofluoric acid were used for surface conditioning. Transverse strength was measured using a universal testing machine and the technique of EPMA(electron probe micro analysis) was used to access the potassium contents. The results were as follows: 1. Improvement in strength was only obtained by treating the surface placed in tension. 2. No changes in the dimensions of the treated specimens were detected when samples were measured with a micrometer. 3. There was significant increase in transverse strength of G-Cera IV group treated with etching and ion exchange, compared with G-Cera II group only treated with ion exchange. 4. From the results of EPMA test, increase in potassium contents was observed on the surface treated with ion exchange paste.

This study analyzed the impacts of programming characteristics perceived by the consumers of entertainment programs on general programming channels on watching intention and the data of a survey with 360 adult viewers in the capital area. Research questions were verified as follows: First, as a result of multiple regression to analyze the impacts of the factors of programming characteristics perceived by the consumers on their watching intention, setting personal characteristics as a control variable, programming characteristics as an independent variable and watching intention as a dependent variable, the regression model was significant. Thus, the more positive the perceived factors of programming characteristics, the more significant their watching intention improved. Second, the factors of programming characteristics significantly affecting watching intention had greater positive(+) impacts in the following order: Adjacency > substantiality > weight of genre > social evidence > relative advantage > ease of access.

It may not be strange to anticipate that the forth-coming epoch of electronic government would bring us lots of convenience on account of ubiquitous environment with mobile devices. Such environment enables us to access the up-to-date information anytime and also a worker to carry out administration services to perform one's line of duty at anytime with electronic, handy devices such as PDA. What we now recognize from the field of electronic traffic administration services is that the office work flow as well as the public services has been remarkably improved by using of not only text but video and image information under the distributed, mobile environment. One of key requirements of this kinds of services is the feature of exchanging various information among multiple information publishers and subscribers. We call this feature Messaging Services generally The study in this paper focuses on the architecture design of the Messaging Engine software, complying with the pattern-oriented software architecture design methodology. And our contribution also goes to the discovery of three architecture patterns found in the design process and the efficient multi-threading architecture compared to one of the Messaging Engine solutions.

In the post-genomic era, researches on proteins as well as genes have been increasingly required. Particularly, work on protein-protein interaction and protein network construction have been recently establishing. Most biologists publish their research results through papers or other media. However, biologists do not use the information effectively, because the published research results are very large. As the growth of internet field, it becomes easy to access these research results. It is important to extract information with a biological meaning from various media. Therefore, In this paper, we efficiently extract the protein information from many open papers or other media and construct the database of the extracted information. We build a protein network from the established database and then design and implement various pathway analysis algorithms which find biological meaning from the protein network.
