In this paper, by using agent technology, we proposes and implements the search system that supplies the result close to the user preference through the analysis of user preference. To offer better qualified information to user without redundant search results and unnecessary information of legacy search system. this system uses user's information and generates keywords and categories. Comparing user's favorite category with search result of legacy search system through the agent oriented search engine, it supplies only the result close to the user's category. At the same time, search result is saved into the databases according to each category to be used for search work later. As a result, the redundant information of search result was efficiently removed and the information close to the user's favorite category was obtained.

삼복(三伏; 초복, 중복, 말복)은 한국의 전통적인 세시풍속이면서 오늘날에도 널리 알려져 있는 잡절 중의 하나이다. 한국천문연구원에서 매년 발간하는 역서나 1900년부터 2100년까지의 역일 자료를 계산한 "만세력"에도 삼복 일자를 표시하고 있다. 이 논문에서는 역 관련 자료들을 분석하여 조선시대 삼복 일자의 결정법에 대하여 연구하였다. 현재 규장각에 소장되어 있는 "작력식(作曆式)", "증보작력식(增補作曆式)"에 의하면 초복과 중복은 하지로부터 각각 3번째, 4번째 경일(庚日), 말복은 입추로부터 1번째 경일이며, 만일 하지가 경일인 경우에는 하지일로부터 3번째 경일을 초복으로, 입추가 경일인 경우에는 입추 시각이 오전인 경우 그날을 말복으로 오후인 경우 다음 경일을 말복으로 한다고 되어 있다. 먼저 하지나 입추가 경일이 되는 해를 분석한 결과 일반적으로 하지 시각이 오전인 해의 2년 후에는 시각이 오후인 해가 있었고, 19년 후에 다시 하지 시각이 오전인 해가 돌아옴을 알 수 있었다. 그러나 종종 2+19년 주기가 아닌 2+17년 주기로 나타나는 경우도 있었다. 삼복 일자와 관련하여서는 적어도 1752년(정조 22) 이후부터는 "증보작력식"의 삼복 결정법이 사용되었음을 확인 할 수 있었다. 그러나 일제 강점기에 편찬된 1930년의 역서를 제외하고는 1861년(철종 12) 이후부터는 남병길의 "추보첩례(推步妾例)"에 따라 입추 시각에 무관하게 그날이 경일이면 말복으로 하였음을 알 수 있었다. 현재에는 삼복 결정법에 대한 법적 규정이 없이 "추보첩례(推步妾例)"의 방법이 사용되고 있다.

In the Internet based information technology community, the exchange of product information is more activated in e-commerce of B2C and B2B. We have suggested a XML based unified product description model with which all kinds of product informations can be represented. This model also has a feature to avoid duplication of the product information. In this paper, we will implement this model using Java Beans and EJB (Enterprise Java Beans) of the Java component technology, and then test this system over several products on the web. finally, we will analyze the effect due to the removal of the information duplication.

In the three-dimensional analysis and deformation analysis of large structures, efficient is the use of the multiple method of close range photogrammetry which approaches the object distance. This study analyzes the influence of errors according to the overlap, the control points, and the object distance, to solve the problems which are raised in the multiple method. A wall-board, 7 meters by 3 meters, was used as a test field on which a total of 225 unknown points were equally disposed. The photographs with changing the overlap and object distance were taken by P-31 camera system. a total of 143 negatives are used in this study for computing 3-dimensional coordinates and its standard errors, and bundle adjustment of strips and blocks developed with on-line system is applied. In case of decreasing the number of control points, simulation error increases but actual error decreases and increases again. Due to the changed of object distances Z error represents largely compared to X, Y error, but good results in Z can be obtained by increasing the redundancy. And simulation error or actual error shows best results at the endlap of about 70%. To sum up this study, approprate arrangement of control points and overlap is meaningful, and multiple method by short object distance will be widely used to precision and deformation analysis of critical structures.

Multiplex ligation dependent probe amplification (MLPA) is a PCR-based method to detect gene dosage. Since its introduction, MLPA has been used to test a large number of genes for major deletions or duplications. Genetic testing, as a diagnostic tool for genetic disease, has been used primarily to identify point mutations, including base substitutions and small insertions/deletions, using PCR and sequence analysis. However, it is difficult to identify large deletions or duplications using routine PCR- gel based assays, especially in heterozygotes. The MLPA is a more feasible method for identification of gene dosage than another routine PCR-based methods, and better able to detect deleterious deletions or duplications. In addition to detection of gene dosage, MLPA can be applied to identify methylation patterns of target genes, aneuploidy during prenatal diagnoses, and large deletions or duplications that may be associated with various cancers. The MLPA method offers numerous advantages, as it requires only a small amount of template DNA, is applicable to a wide variety of applications, and is high-throughput. On the other hand, this method suffers from disadvantages including the possibility of false positive results affected by template DNA quality, difficulties identifying SNPs located in probe sequences, and analytical complications in quantitative aspects.

Bid-rigging is a common issue in public construction projects, and appropriate sanctions are required from the relevant authorities. This study analyzes the need for an optimal enforcement model to prevent bid-rigging by considering both civil and criminal aspects. Recently, there have been overlapping sanctions under the Fair Trade Act, such as fines imposed by the Fair Trade Commission and civil lawsuits filed by the client for damages. The purpose of this study is to evaluate the effectiveness of penalty surcharges and compensation systems for preventing bid-rigging, and to consider the possibility of overlapping sanctions in public construction projects. It was found that overlapping sanctions under the Fair Trade Act can be helpful in improving the system. However, in cases where the state is the plaintiff for damages in a lawsuit, it is necessary to consider the penalty surcharge and sentence, reduce the penalty surcharge for joint acts, refund the surcharge after a final judgment, and consider the damage compensation system when imposing a surcharge. This study contributes to the development of an efficient enforcement model to suppress bid-rigging in public construction projects by analyzing the improvement effects of sanctions and compensation.

Twenty-first century will be in the era of culture and art as postmodernims progresses, therefore, geography which is is traditionally concerned with regional study needs to deeply study the culture of region. Regional symbols are clue to identify regional culture which is environments of symbolic space. Especially the study of urban culture come to the needs of times with occurring global city, urban symbols make clear urban culture and urban identity. The aim of this paper is to analyze urban symbols, that is urban songs, urban birds, urban trees, urban flowers to study urban culture in korean cities, urban symbols make clear urban spatial environment which is natural and human, and then, urban symbols make clear urban identity. The analytical results of lyrics of urban songs in the 76 cities of korea include names of mountain, river, sea and place, the names of mountain and river make clear urban identies which is natural and human characteristics, it is environment of symbolic space which brings unity, one body. Especially it is environment of symbolic space which comprise fung-soo(風水) aspects, place names well represent symbolic space. The analytical results of symbolic things, that is urban birds, urban trees, urban flowers in the 78 cities of korea indicate they are gain and gain established, they are also our environments of symbolic space which is curtual settlings of our life, but they are imported not native species but foreign species which have not environment of symbolic space. The results of this paper implicate urban symols should review. because urban symbols fit to our natural and human environments of symbolic space.

This paper presents a multi-costraint optimization model for redundant system reliability. The optimization model is usually formulated as a nonlinear integer programming (NIP) problem. This paper reformulates the NIP problem into a linear integer programming (LIP) problem. Then an efficient 'Branch and Straddle' algorithm is proposed to solve the LIP problem. The efficiency of this algorithm stems from the simultaneous handling of multiple variables, unlike in ordinary branch and bound algorithms. A numerical example is given to illustrate this algorithm.
