농가를 방문하는 가금관련업체의 관계자 및 차량은 HPAI 질병 확산의 매개체가 된다. 농가들의 가금관련업체 이용 정보를 이용하면 농가간의 연결을 확인할 수 있고 HPAI 확산 가중 네트워크를 구성할 수 있다. 네트워크 분석중 중심성 측정은 질병에 취약하거나 타 농가에 영향력이 큰 역할을 하는 농가를 분석하는 방법으로 HPAI 초기 확산을 통제하는 방법으로 이용된다. 단, HPAI 바이러스는 네트워크의 연결선 가중치에 따라서 확산 경로가 달라질 수 있다. 기존의 분석 방법은 확산 경로에 있어 대치되는 연결선의 강도와 연결선의 수 중 하나만을 고려하기 때문에 질병 확산을 정확히 모의하는데 한계가 있다. 그래서 본 연구에서는 2008년 발병한 한국 김제 지역의 39개 농가를 대상으로 가금관련업체 이용자료를 적용한 HPAI 확산 네트워크에 연결선의 가중치에 지수를 적용하는 방법으로 기존의 방법과 결과를 비교했다. 이 자료는 가금 산업 네트워크의 한국 지역 농가 적용성을 평가 할 수 있을뿐만 아니라 추후 잠재적인 질병 발병 차단을 위한 정보 제공에 중요한 역할을 할 것이다.

The Muryangsa temple five-storied stone pagoda (Treasure No. 185) was geographically located in the area of the Baekje Kingdom. The architectural style of the Muryangsa temple five-storied stone pagoda is the pagoda at the early Goryeo Dynasty that was succeeded technique of the Baekje Kingdom and form of the Shilla Kingdom. Because this pagoda is located outside during old time that it received serious petrological and biological weathering in rock blocks and occurred the center subsidence in the upper capstone. This study executed ground stability interpretation in order to know what central subsidence in the upper capstone occurred for soft ground. The ground stability interpretation used seismic survey, electrical resistivity survey and GPR survey by non-destructive method. As the result, the ground appeared in the condition which is good. Specially, high resistance zone appeared from electric resistivity survey which come to seem with ground reinforcement harden. Consequently, central subsidence condition in the upper capstone is not by the instability of ground, and is judged with the thing by the structure instability in rock blocks over the upper capstone. This will be applied basic data with the long-term monitoring or preservation countermeasure of the pagoda.

As technology progresses, the supply and use of smartphones has become increasingly popular and has significantly transformed modern life. However, users still feel uncomfortable running some mobile apps, as many are created without a thoughtful consideration of usability. Usability evaluations involve several methodologies to identify specific problems in light of various principles. Although usability testing was initially centered on physical services, it has gradually evolved to consider user satisfaction as its main concern. Public transportation applications should be accessible to everyone, and studies should focus on the user's perspective. However, previous user surveys have concentrated on applications' technical aspects or visual design. As a result, there has been a lack of general usability evaluations. This study aimed to evaluate the usability of mobile transportation applications in real life, with a focus on public transportation in Seoul. All the participants were asked to complete a task, an in-depth interview, and a questionnaire survey. In summary, the results suggest that users do not find inappropriate information attractive when it does not satisfy their purpose of use, but rather tend to consider it as interference.

Korea's Rolling stock workshop were established with the introduction of a railway, and became the center of industrial construction in the modern age of Korea. There still exist a lot of Rolling stock workshop buildings in the Youngsan Rolling stock workshop, the representative case of Korean Rolling stock workshop, and especially the study aims to look into modern architectural properties centered on those well-preserved buildings. Korea's Rolling stock workshop were built considering the proper conditions of location such as the neighboring districts from the port to transport vehicles and materials, the place where railroad lines are centralized, the short returning distance of railroad cars for entry and departure, and had the facility layout according to the order of a working process of vehicles, and the unique structure and the section facade shape with proper functions and sizes according to each purpose. In particular, they actively adopted steel-frame structure and reinforced concrete structure, and came to have the initial characteristics of Korea's modern industrial building which is called the structural transition. Therefore, this study aims to highlight the importance of Rolling stock workshop including the Youngsan Rolling stock workshop as industrial architecture heritage in the modern age of Korea.

도시지역은 도시형 수해발생, 갈수시의 급수안전도 저하, 평시 하천유량의 감소, 공공수역의 수질악화, 지하수 오염 등 여러가지 문제에 직면하고 있다. 개발로 인한 수환경의 피해를 최소화하기 위한 대안적인 설계방안이 필요하며, 이를 위해서는 개발 전후 물순환 환경 변화에 대한 정량적인 해석이 가장 우선적으로 수행되어야 한다. 본 연구에서는 우리나라와 일본에서 도시유역에의 적용이 활발한 물리적 개념의 분포형 수문모형인 WEP(Water and Energy transfer Process) 모형을 통해 행정중심복합도시 개발 전후의 물순환 변화를 해석하였다. 정밀한 해석을 위해 대상유역을 100m 크기의 정방형 격자로 구분하고 기상 조건, 지표면 조건, 하천, 토양, 지하대수층, 농업용수 이용 등 물순환에 관련된 광범위한 입력자료는 기존 측정 자료 및 관련 문헌, 현장 조사를 통해 각각 구축하였다. 모의의 전 후처리는 WEP+를 통해 수행되었는데, WEP+는 WEP 모형의 방대한 양의 입력자료를 효과적으로 구축하고, 다양한 시계열 및 공간분포 출력자료를 효과적으로 분석할 수 있는 인터페이스를 지닌 전 후처리 프로그램이다. 개발로 인한 물순환 변화는 절성토로 인한 지형 및 토양 조건 변화, 토지이용 및 용수이용 변화에 대한 개발 계획을 모형 입력자료로 구축한 후, 개발전과 동일한 기상조건과 초기 모의조건 하에서 각각 11년간 모의하여 수문 요소 변화를 비교하는 방법을 사용하였다. 물순환 해석 결과는 개발 전후 모의에 대해 유황곡선 및 물수지, 수문요소 공간분포 비교를 통해 수행하였다.

This study tried to reveal the relation among the necessary and sufficient conditions of human relation, which is the core concept of human-centered counseling. The relation of these three conditions are quite different according to what we take as the main content of authenticity. If we take congruence as its content, as Rogers did in his early academic years, three conditions are equal in their importance as instruments which counselor can use. But, if we take presence as its content, as Rogers did in his later academic years, authenticity possesses central position while using empathy and unconditional positive regard as its instruments. In this relation, we can say authenticity is a continuous growing process of self realization. And it also can be sad that the three necessary and sufficient conditions compose productive counseling relation inviting both counselor and client to the self realizing process.

The virtual world is a cyber gaming space where a player interacts with others through their avatars. It is now mainly developed in foreign countries including USA, Canada, and Europe and many experts say that the market capacity of virtual world will be continually expanded in worldwide. The virtual world will mostly be made such that a user accesses the world for free and pays for in-game activities. But it is hardly that we find the effective methodology of payment system for such virtual world due to its' short development history. In the case of Korea, various payment methods of selling in-game assets have been tested in online games. The paper propose an effective revenue model for social virtual world focused on selling in-game assets. The guideline of the proposed revenue model will be expected to contribute creating revenue focused on selling in-game assets, effectively for social virtual world.

In this paper, a new tube-radius-measuring algorithm has been proposed for effectively measuring the radii of small tubes under severe noise conditions that can also perform well when metal scraps that make it difficult to measure the radius correctly are inside the tube hole. In the algorithm, we adopt a fuzzy searching method that searches for the center of the inner circle by using fuzzy parameters for distance and orientation from the initial search point. The proposed algorithm has been implemented and tested on both synthetic and real-world tube images, and the performance is compared to existing circle-detection algorithms, such as the Hough transform and RANSAC methods, to prove the accuracy and effectiveness of the algorithm. From this comparison, it is concluded that the proposed algorithm has excellent performance in terms of measurement accuracy and computation time.

This study attempts to find out the characteristics of digital currency and currency transformation through the analytical descriptions of the literature. In the early days of the emergence of new currency, market-oriented autonomous monetary adjustment was made along with various attempts by the private sector, and then government-centered central currency management and coordination were made for the national monopoly of profits and power. Digital currency can be seen as the emergence of a new form of money that will bring about paradigm changes. CBDC can be divided into direct and indirect types. CBDC is expected to require a strategic approach by the government or firm as it will bring about changes in the ecosystem of related industries. Libra is a stablecoin designed to minimize price fluctuations, and if it succeeds in commercializing it, it is expected to bring about revolutionary changes in the financial industry around the world.
