R&D Personnel information is constructed locally based on the needs of each institute and therefore is distributed over different databases. It does not support inter operability which makes it difficult to access and update that leads to the problem of ineffective usage. In this study, we have categorized the lower level information that forms the domestic S&T Personnel and defined the relationship between each type of information to suggest a standard for the data elements that guarantee the access to specific information in order to support inter operability. We have analyzed the human resource information database of domestic and foreign research institutes for the data modeling. We have also made reference to the standard metadata and database of other types that can be linked with the human resource information in designing the data elements. ISO/IEC 11179, the international standard for the metadata registry(MDR), was adopted to apply the object, attribute and expression to be described to the name of the data element.

The operation of the theater's seasonal program is an important service for the stability of theater management and audience development. However, the domestic theater season system has been around for 20 years, but still has not been established in practice compared to overseas theaters, and academic research is also lacking. Therefore, in this study, the government wanted to draw out elements of 'season system' program services and additional services provided by domestic and foreign theaters, and to calculate the importance of each attribute to suggest a plan to operate a seasonal service suitable for the actual conditions in Korea. Thus, through the analysis of seven theater seasonal programs, a study model consisting of two higher, seven median and 23 lower factors was derived. Based on this survey, 14 theater experts were asked to compare the priorities of each factor. Studies have shown that the composition of packages and works in program services is important, and that monetary factors are important in additional services. In other words, an important element in the seasonal system is judged to be the need to upgrade program services and selectively operate a small number of additional services with large audience needs to attract audiences.

A 10 months old, male Poongsan dog was referred with a history of right forelimb lameness due to hit by a car a few hours before presentation. On the physical examination, the dog showed pale mucous membrane, respiration distress, and skin abrasions. The main laboratory finding was leukocytosis, while hematocrit was normal. Abdominal radiography revealed the loss of abdominal serosal detail, which was diagnosed as peritoneal hemorrhage on ultrasonography (US) and aspiration. On computed tomography (CT), hepatic and splenic injuries were seen characterized by the discontinuity of the capsule with irregular margin and lower density lesions than parenchyma. No contrast enhancing area were shown in the laceration lesion. The accessory spleen was incidentally found by US and CT. In this case, acute intra-abdominal hemorrhage from splenic and hepatic laceration was diagnosed using CT.

This study aims at finding out major factors affecting the attitude, intention and behavior on Mobile advertising and figuring out what their differences between genders are. To do this, new variations such as personalization, permission and incentive are suggested, as well as variations proven by the previous studies. The findings show us that while entertainment, informativeness, credibility, personalization and permission had a positive effect on attitude toward Mobile advertising, irritation had a negative effect on it. Incentive had a positive influence on intention for mobile advertising. Attitude toward mobile advertising had a meaningful influence on intention, and the intention had a meaningful influence on behavior. At last it was revealed that gender difference has a meaningful influence. This study was carried out to find out the effects that evaluation variations have on attitude, intention and behavior on the nature of Mobile advertising. Therefore, it has a significance that gives a theoretical suggestion in that through its evaluation, some considerations are offered at the time of implementing the Mobile advertising, and the basic difference between genders can be explained as well.

A topic map was designed as an efficient information retrieval method that is optimized for classification, organization, and navigation through the use of a semantic link network above information resources. With this, this study aims to design a topic map-based university archives retrieval system to provide the relevant information retrieval. For this study, electronic records that relate to the academic administration within two years of D university were collected, and topic map editing was carried out with Ontopia Omnigator. Topics were classified according to their functional analysis of academic administration. In the end, the number of topics was finalized as 626, with 6 types in general: academic work, staff, college register, student, university, etc. Association was separated into six types as well, which were formed with consideration to the relationships among topics. In addition, there are seven occurrence types: register class, register number, register date, receiver, title, creator, and identifier. It is expected that the associative nature of the designed topic map-based retrieval system in this study will make navigation of large records easy and allow incidental discovery of knowledge.

As the 4^th industrial revolution has been an emerging issue, the government and industry has paid increasing interest to smart factory. The Korean government has made efforts to establish smart manufacturing capabilities of small-to-medium sized firms by providing supports for smart factory. However, the effectiveness of the supports and satisfaction of firms have hardly been analyzed. This study aims to analyze firms' satisfaction by attributes of policy suuports for smart factory and identify priorities for government supports. The results show that 8 out of 11 attributes were one-dimensional and 3 were attractive attributes. Among the 11 attributes, funding support was the top priority. The attributes such as dispatching external experts, consulting for sophistication of smart-factory, and consulting for maintenance and repair were also high priorities. These results imply that firms prefer supports for maintenance and sophistication to adoption or initial establishment of smart factory.

The research of the preserving privacy of sensitive information has been popular recently. Many researches about the techniques of generalizing records under k-anonymity rules have been done. Considering that data anonymity requires a lot of time and resources, it would be important to decide whether a table is vulnerable to privacy attacks before being opened in terms of the improvement of data utilization as well as the privacy protection. It is also important to check to which attack the table is vulnerable and which of anonymity methods should be applied in the table. This paper describe two possible privacy attacks based upon related references. Also, we suggest the technique to check whether data table is vulnerable to any attack of them and describe what kind of anonymity methods should be done in the table. The technique we suggest in this paper can also be applied for checking the safety of anonymity tables in which insert or delete operations occurred as well from privacy attacks.

Block-transform coding is one of the most popular approaches for image compression. For example, DCT is widely used in the internaltional standards standards such as MPEG-1, MPEG-2, JPEG, and H.261. In the block-based transform coding, blocking artifacts may appear along block boundaries, and they can cause severe image degradation eqpecially when the transform coefficients are coarsely quantized. In this paper, we propose a new method for blocking artifacts reduction in transform-coded images. For blocking artifacts reduction, we add a correction term, on a block basis, composed of a linear combination of 28 basis images that are orthonormal on block boundaries. We select 28 DCT kernel functions of which boundary values are linearly independent, and Gram-Schmidt process is applied to the boundary values in order to obtain 28 boundary-orthonormal basis images. A threshold of bolock discontinuity is introduced for improvement of visual quality by reducing image blurring. We also investigate the number of basis images needed for efficient blocking artifacts reduction when the compression ratio changes.

The latest E-commerce sites provide personalized services to maximize user satisfaction for Internet user The collaborative filtering is an algorithm for personalized item real-time recommendation. Various supplementary methods are provided for improving the accuracy of prediction and performance. It is important to consider these two things simultaneously to implement a useful recommendation system. However, established studies on collaborative filtering technique deal only with the matter of accuracy improvement and overlook the matter of performance. This study considers representative attribute-neighborhood, recommendation textile set, and similarity grouping that are expected to improve performance to the recommendation agent system. Ultimately, this paper suggests empirical applications to verify the adequacy and the validity on this system with the development of Fashion Design Recommendation Agent System (FDRAS ).
