Recently, BIM (Building Information Modeling) has been attracting attention as a next-generation architectural design tool. The strength of BIM technology is that it enables collaborative work and it is shared in real time. The Revit program, an architectural design program for BIM technology, enhances the information input side, making it possible to know the information of components at the design stage. However, in the use of the Revit program, it is impossible to share or reuse a family created by one designer with another designer. In order to overcome this inefficiency, we designed the design drawing as an Excel file and made it easy to create.

The purpose of this study is to provide basic data on sports entertainment programs by collecting data on unstructured data generated by Naver and Google for SBS entertainment program 'Women Who Score Goal', which began regular broadcast in June 2021, and analyzing public perceptions through data mining, semantic matrix, and CONCOR analysis. Data collection was conducted using Textom, and 27,911 cases of data accumulated for 16 months from June 16, 2021 to October 15, 2022. For the collected data, 80 key keywords related to 'Kick a Goal' were derived through simple frequency and TF-IDF analysis through data mining. Semantic network analysis was conducted to analyze the relationship between the top 80 keywords analyzed through this process. The centrality was derived through the UCINET 6.0 program using NetDraw of UCINET 6.0, understanding the characteristics of the network, and visualizing the connection relationship between keywords to express it clearly. CONCOR analysis was conducted to derive a cluster of words with similar characteristics based on the semantic network. As a result of the analysis, it was analyzed as a 'program' cluster related to the broadcast content of 'Kick a Goal' and a 'Soccer' cluster, a sports event of 'Kick a Goal'. In addition to the scenes about the game of the cast, it was analyzed as an 'Everyday Life' cluster about training and daily life, and a cluster about 'Broadcast Manipulation' that disappointed viewers with manipulation of the game content.

The purpose is to evaluate evacuation safety by simulating the toxic effects of hydrogen fluoride leaks in areas surrounding national industrial complexes and to suggest alternatives for areas that do not satisfy evacuation safety. For human casualties caused by hydrogen fluoride leakage accidents, Available Safe Egress Time (ASET) is calculated by the toxic effects quantified with the Areal Locations of Hazardous Atmospheres (ALOHA), an off-site consequence assessment program. The Required Safe Egress Time (RSET) is calculated through Pathfinder, an evacuation simulation program. Evacuation safety is assessed by comparing ASET and RSET. The ALOHA program was used to evaluate the time to reach AEGL-2 concentration in 12 scenarios. The Pathfinder program was used to assess the total evacuation time of the high school among specific fire-fighting objects. Of the 12 accident scenarios, ASET was larger than RSET in the worst-case scenarios 1 and 9. For the remaining 10 accident scenarios, the ASET is smaller than the RSET, so we found that evacuation safety is not guaranteed, and countermeasures are required. Since evacuation safety is not satisfactory, we proposed to set up an evacuation area equipped with positive pressure equipment and air respirators inside specific fire-fighting objects such as the high school.

In this study we explain the necessity of a developing management system of academical achievement in a progrm running the accredited engineering program as an observation and management tool to assure students' succesive achievement of program outcomes, and also present an operation result of the constructed management system. Taking the electronic engineering program in our school as an object, we constructed a relating database to monitor the students' course work completions and achievement of program outcomes, to allow students to build their plans for course work and to enable professors to proceed customized counseling for assigned students. The constructed system also provide various statistics relating program outcomes to allow program professors to proceed effective management of outcomes in the program level. In this paper we show that it is possible to calculate and provide the various statistical indicators, which is needed to effectively run accredited engineering programs, by presenting the results relating successful construction of the system and its operation.

By recent development of wired and wireless communication technology, any service can be delivered through broadcasting networks or communication networks. So contents consumers want to receive broadcasting program via any accessible network. Network independent broadcasting system can receive optimized multimedia contents by combining the high-quality multimedia contents transmitted through broadcasting network and the additional contents delivered through communication network. Additional contents can be other multimedia contents, URL of contents, some texts for indicating information of received multimedia, etc. Network independent broadcasting system is in early stage of development, and receivers and the monitoring system for hybrid broadcast are under development. Thus the multiplexing method and demultiplexing method to perform hybrid broadcasting is on study. In this paper, we designed the demultiplexing algorithm to perform hybrid broadcasting system and implemented demultiplexer system based on modulator interface system standard T2-MI of DVB-T2.

This study analyzed the accomplishment of the outsourcing production policy which forces broadcasting companies to schedule and broadcast more than a certain proportion of outsourcing production programs. According to the results from the examination of whether or not the policy increased the diversity of broadcasting programs, it is positive that a rise in the number of production companies resulting from the implementation of the outsourcing production policy increased the diversity of broadcasting program makers, but programs supplied were limited to certain genres, failing to be diverse. According to the results from the examination of whether or not the competitiveness of broadcasting and video contents increased, production conditions had not improved due to the controversy over the ownership of the right of production between terrestrial broadcasting companies and outsourcing production companies. In addition, though there was the positive effect of increasing export of broadcasting programs, the exports were limited to certain genres.

Nowadays, as it goes on digitalization of the broadcasting and the convergence of the broadcasting and communications , it has been developed into the ubiquitous individual media consuming pattern which can easily and comfortably consume the favorite contents through any devices at anytime and/or anywhere. For this, in this paper, we propose personalized broadcasting service that can provide a convenient access of the contents that users want to watch at anytime by considering the user preference and consumption characteristics as well as an efficient browsing and watching of the particular program segments more advanced than the data broadcasting services. Moreover, it is implemented the TV-Anytime standard based on personalized broadcasting terminal platform by us. The developed services and terminal will used on broadcasting environment in which many services and the contents. The result of that is the broadcasters/service providers and content providers can provide differential broadcasting services which is suitable to each user such as personalized broadcasting service in near future.

This paper describe the passive intermodulation products(PIMs) which are formed in high power Ku-band transponder and antenna subsystem on the Communication St Broadcasting Satellite(CBS)program when two transmit carriers beat together to generate harmonics that fall into the receive band. How the PIMs are initially generated and the effect of PIMs for Ku-Band payload system are analyzed by calculating the PIMs frequencies and the power level of PIMs.

Unlike traditional analog broadcasting, digital broadcasting provides users with various additional services that we have never seen before. To receive these kind of services. data broadcasting includes not only audio, video signal, but also additional data associated with the program. In this paper, we present the efficient parsing and caching mechianism for data carousel in digital broadcasting set-top box. In order to speed up the process of parsing, we use the Message Pool that stores elementary_pid syntax of DSM-CC message packets.
