21세기는 디지털 기술의 발전으로 방송과 통신의 영역이 없어지고, 관련된 모든 통신 매체가 통합하여 폭넓은 서비스 제공을 가능하게 할 것이다. 또한 2001년 HDTV 방송이 수도권을 중심으로 시작되고, 위성방송채널도 100개이상 허가될 예정이므로 우리나라도 다채널 TV 방송 시대가 도해하게 되었다. 따라서 본 논문에서는 ISDB 시대의 TV 방송의 미래 환경과 서비스 영역을 고제하고, 한반도 주변 한글 문화권 형성을 위한 위성방송 기술을 분석하여 맞춤형으로 디지털 화면책 출판을 서비스하는, 새로운 대화형 독서출판 위성 TV 전승 시스템을 제안 하였다.

Masonry is a composite non-homogeneous structural material, whose mechanical properties depend on the properties of and the interaction between the composite components - brick and mortar, their volume ratio, the properties of their bond, and any cracking in the masonry. The mechanical properties of masonry depend on the orientation of the bed joints and the stress state of the joints, and so the values of the shear modulus, as well as the stiffness of masonry structural elements can depend on various factors. An extensive testing programme in several countries addresses the problem of measurement of the stiffness properties of masonry. These testing programs have provided sufficient data to permit a review of the influence of different testing techniques (mono and bi-axial tests), the variations caused by distinct loading conditions (monotonic and cyclic), the impact of the mortar type, as well as influence of the reinforcement. This review considers the impact of the measurement devices used for determining the shear modulus and stiffness of walls on the results. The results clearly indicate a need to re-assess the values stated in almost all national codes for the shear modulus of the masonry, especially for masonry made with lime mortar, where strong anisotropic behaviour is in the stiffness properties.

As offshore activities move into deeper ocean, conventional fixed-base platforms drastically increase in size and cost, One of alternatives available is a guyed tower, in which environmental loads are supported by guylines instead of structural members. The guying system of the guyed tower is designed on one hand to be stiff enough to limit the structural displacement in normal operations, but on the other hand to be soft enough to permit large slow sways during the presence of design-level storms. This compliancy provides an efficient means of withstanding harsh environment so that the disproportionate increase in size of deep water platforms can be kept to a rational limit. Novel configurations contain always some degrees of potential risks mainly due to the lack of experience. The most critical hazard inherent to a guyed tower may be the pullout of anchor piles. Once it happens, the guyline fails to function and it may eventually lead to the total collapse of the system. It is the aim of this paper to discuss and quantify the anchor-pullout risk of a guyed tower. A stochastic analysis is made for evaluating the first-upcrossing probability of the tension acting on anchor piles over the uplift capacity. Nonlinearities involved in the mooring stiffness and hydrodynamics are taken into account by using time-domain analysis. A simplified two dimensional dynamic model is developed to exemplify the underlying concept. Real hurricane data in the Gulf of Mexico spanning over 70 years are incorporated in a numerical example of which result clearly indicates highly potential risk of anchor pullout.

EPS-TOPIK is a test of Korean proficiency which is enforced at the level of Korean government for the selection of competent foreign workers. Therefore, it must ensure validity and reliability, and practicability as a language assessment tool. For seeking a way of developing EPS-TOPIK, in this paper, the current state of EPS-TOPIK was investigated based upon the materials published by the Korean government, and the questions of EPS-TOPIK were analysed. Together with this, newspaper articles both in Korea and in foreign countries were also analyzed, and the directors of the EPS center abroad were interviewed. According to the survey results, as expected, the local environment of Korean education is poor in a number of ways to improve the Korean communication skills of foreign workers, as well as to prepare the EPS-TOPIK. To improve the efficiency of the EPS-TOPIK and to enhance the Korean communication skills of foreign workers, the Korean language institutions including the King Sejong Institute, which are in charge of the Korean language education should closely cooperate with the Human Resources Development Service of Korea, which is responsible for all of the influx of foreign workers.

The advent of Internet of Things (IoT) makes common nowadays computing environments involving programming not a single computer but several heterogeneous distributed computers together. Developing programs separately, one for each computer, increases programmer burden and testing all the programs become more complex. To address the challenge, this paper proposes an RPC-based unified programming language, UniPy, for development of MGC (eMbedded, Gateway, and Cloud) applications in IoT systems configured with popular computers such as Arduino, Raspberry Pi, and Web-based DB server. UniPy offers programmers a view of classes as locations and a very simple form of remote procedure call mechanism. Our UniPy compiler automatically splits a UniPy program into small pieces of the program at different locations supporting the necessary RPC mechanism. An advantage of UniPy programs is to permit programmers to write local codes the same as for a single computer requiring no extra knowledge due to having unified programming models, which is very different from the existing research works such as Fabryq and Ravel. Also, the structure of UniPy programs allows programmers to test them by directly executing them before splitting, which is a feature that has never been emphasized yet.

The purpose of this study is to examine the status and limitations of the activation plan as a result of the change in urban regeneration paradigm. In particular, the change in housing life was considered following the guidelines of the New Deal project. Specifically, the three types - General Neighborhood, Housing Support, and DongneSaligi - were analyzed from the perspective of organization, space and program. In addition, the master plan and unit project, the organization and progress, and the budget plan were reviewed. As a result, the New Deal project for urban regeneration is importance on economic regeneration, which, unlike the integrated and continuous guide proposed by the government, could limit the individual progress of transitional organizations, 2-dimensional planing and various programs. Thus, first, in order to supplement the organization's verticality and inefficiency in progress, the annual business assessment should be discouraged and the permit and progress of the project should be determined at the local government level. Second, integrated and multidimensional planning is necessary to produce synergy effects in the physical environment. Finally, the link between program unit projects and the economic effects can be considered.

The purpose of this study was to understand the timing of Gentrification by the study through the analysis of licensing data for food service businesses under the correlation with regional policies and systems. In addition, by analyzing the change in location patterns of the food service business in the district unit plan zones, the cause, development patterns and regional differences were identified. Starting with the Seoul hanok declaration in 2008, the approval of the food service business began to increase, and the floating population increased with the restoration of the Suseong Valley in 2012, and the concentration of food service business increased significantly on the waterway (Jahamun-ro 7-gil). Since the designation of Ikseon-dong as an urban environment readjustment zone in 2004, the approval of new food service business has been very low until around 2014, when the cooperative establishment committee is dissolved, and as the district unit plan for the preservation of hanok and regional management is being established, the number of new permits has exploded to date and restaurants in hanok conservation zones has been active.

This study examines the significance and problems of the Fourth Amendment to the Fisheries Act, which went into effect in January 2023. Following the passage of the Aquaculture Industry Development Act, the fourth amendment to the Fisheries Act sought to reform the fisheries legislative framework, while also including significant changes. In particular, a number of new systems for managing fishing gear have been implemented, and local governments now have some autonomy in fisheries management, which has allowed for adjustments to be made to meet the needs of the fishing industry and changes in socioeconomic situations. However, as independent legislation for each fisheries sector continues, the subject of regulation under the Fisheries Act, as well as the Act's position as a basic legal system, has been continuously reduced, overshadowing the Act's objective. As a result, a full-fledged assessment of changing the legislation's name in the future is required, as well as addressing issues such as the lack of difference in the legislative purpose clause and the necessity for further revision of the definition clause. Therefore, any future revisions to the Fisheries Act should aim to overhaul the existing framework, including fishing licenses and permits.
