도시가스 시공은 특수분야로서 경험이 없으면 시공하기 힘들다. 또한 가스 시공은 국민의 재산보호와 직결되어 있으므로 시공 과정에서 많은 서류가 필요하고 인허가 및 안전점검이 특히 요구된다. 대한설비건설협회 가스설비공사협의회(위원장 이효련)는 지난해 한국도시가스협회와 협의를 통해 도시가스 사용자공급관(공동주택 등)의 행정절차 및 제출서류 간소화 및 표준화와 함께 현장에서 만연하고 있는 도시가스사의 부당행위를 강력하게 건의한 결과 이를 시정조치하여 가스시설시공업 회원사의 경영환경을 크게 개선했다. 본지는 도시가스 사용자 공급관 업무처리 절차를 살펴본다.

The direct and indirect damages caused by fires in underground utility tunnels have a great impact on society as a whole, so efforts are needed to prevent and manage them in advance. To this end, research is ongoing to prevent disasters such as fire flooding by applying digital twin technology to underground utility tunnels. A network is required to transmit the sensed signals from each sensor to the platform. In essence, it is necessary to analyze the application of wireless networks in the underground utility tunnel environments because the tunnel lacks the reception range of external wireless communication systems. Within the underground utility tunnels, electromagnetic interference caused by transmission and distribution cables, and diffuse reflection of signals from internal structures, obstacles, and metallic pipes such as water pipes can cause distortion or size reduction of wireless signals. To ensure real-time connectivity for remote surveillance and monitoring tasks through sensing, it is necessary to measure and analyze the wireless coverage in underground utility tunnels. Therefore, in order to build a wireless network environment in the underground utility tunnels. this study minimized the shaded area and measured the actual cavity environment so that there is no problem in connecting to the wireless environment inside the underground utility tunnels. We analyzed the data transmission rate, signal strength, and signal-to-noise ratio for each section of the terrain of the underground utility tunnels. The obtained results provide an appropriate wireless planning approach for installing wireless networks in underground utility tunnels.

We conducted a survey in collaboration with the Chungcheongbuk-do Office of Education to assess the current status of collections in public libraries affiliated with the Office of Education. The objective of this survey was to identify the current challenges and determine when these libraries are expected to reach a state of collection saturation. Libraries under the jurisdiction of the Chungcheongbuk-do Office of Education are currently facing significant challenges due to severe collection saturation. This underscores the pressing need for the systematic expansion and operation of a collaborative preservation library for a swift response. In the future, it appears that the focus during the transfer process will primarily be on transferring collection-oriented materials. Given the difficulty in providing preservation facilities at individual library levels, materials with preservation value, such as rare books and specialized resources, will need to be transferred to the collaborative preservation library. Additionally, the development of policies and regulations related to material preservation seems necessary. Furthermore, when transferring materials to the collaborative preservation library in the future, it appears that criteria for material transfer will be needed, particularly concerning issues such as a decrease in usage rates for less frequently accessed materials. Subsequent research should consider conducting a survey on the collection saturation status of public libraries under local governments in order to assess the overall need for collection expansion in all public libraries within Chungcheongbuk-do.

The purpose of this study was provide basic data for homemakers' housing notion according to unit size in apartment. This study was conducted by questionnaires that concerning about middle class homemakers whom they lived in Bundang. The results of this study were as follows; 1) In research on the homemakers' general quality, 20pyung unit size was alike 30pyung unit size and 40pyung unit size was similar to 50pyung unit size. 2) Homemakers' perception according to unit size in apartment was various; (a) 20pyungㆍ30pyung unit size-effective household space for husbands' participation, more sports facilities, parking lot space etc. (b) 40pyungㆍ50pyung unit size-homemakers' individual room, ordering and variable unit plan etc. 3) In research on the homemakers' needs, each of unit size was analogous to storage, common facility, new design and new housing form etc.

Weak competitive Small Business are getting attention for their ability to enhance the brand power and marketing co-brand. Under these circumstances, in this study examined the operational status of the domestic co-branded. Also enable co-branding strategy was proposed. First, learn the various aspects of the concept of co-branding, and looked at the advantages and disadvantages of co-branding. Second, the type of co-branded partner combined, joint venture between companies Union type, a leading company driven and private companies and state agencies co-branded. Looked at the type of advantages and disadvantages of each. Thirdly, we presented the current status of the important co-branded domestic. Fourth, we examined the status of the Small and Medium Business Administration supports a co-branded Examined in detail by year look at the status of support for this type of co-branded Industry Distribution and co-branded interrupted. Finally, the short-term aspects and long-term perspective on the domestic co-brand activation strategy based on these materials are presented. The results of this study is expected to be the foundation of domestic co-branded business in the future to explore the ways to improve the system of government support will help to raise.

To get the empirical data of GPR detection and to develop the image prosessing program of GPR detection data, GPR detection were proceed by the underground pipes and cavities buried in the Chamber. In the case of non pavement and asphalt pavement, water filled cavity that was buried in 0.7m depth was able to detection. But in the case of 1.0 m and 1.3 m buring depth, water filled cavity was not able to detection. In the case of non-reinforced and reinforced concrete pavement, it was difficult to detect the cavity caused by signal interference. GPRiPP programs was developed for image processing of the GPR detection data. The major processing algorithm were background removal, stacking and gain function. With proper image processing of gain function and background removal in GPRiPP program, it was showed that similar results can be obtained with conventional image processing program.

가압경수로의 부분충수 운전중 RHR 계통의 기능상실시 사고완화를 위해 가압기 manway와 증기 발생기 출구공동 manway를 동시에 개방한 경우에 대한 실험결과를 CATHAHR2 코드를 이용하여 해석하였다. 해석을 통해 이 경우에 발생하는 물리적 현상을 이해하고 이와 같은 과도기에 대해 코드 예측능력을 평가하므로 써, 실제 원전에서 사고시 적절한 사고대응 방안을 강구하는데 참고가 될 수 있도록 해석적 근거를 제시하고자 한다. 연구결과 CATHARE2 코드는 실험을 통해 관측된 주요 물리적 현상들을 타당하게 예측하였으나, 가압기와 밀림관의 DP를 과대 예측하여 원자로 상부공동의 최대압력을 실험보다 약 7kPa 높게 예측하였다. 노심 노출시간도 노심에서 기포율 분포를 비현실적으로 예측하여 실험보다 약 500초 지연되었다. 실험과 코드의 모의결과를 통하여 노심 노출은 중력주입에 의한 냉각수 보충만으로 충분히 회복될 수 있음을 확인하였다. CATHARE2 코드는 비록 상세한 현상들에 대해 다소 불확실성을 내포하였으나, 전반적인 거동분석에는 타당한 것으로 판단된다. CATHARE 코드는 노심에서 계면 마찰력을 줄임으로써 노심의 차압을 개선할 수 있었고, guide 튜브의 위치를 고온관 중심선과 일치시켜 guide 튜브내 액체의 hold-up 기간을 개선할 수 있었으며, 가압기의 계면 마찰력을 증가시켜서 밀림관에서 "plug and clearing" 현상을 모의할 수 있었다.모의할 수 있었다.
