This study explores the emergence of a modern form of Cheongju-eup townscape in the late 1930s by re-examining the 1960s restoration model of Seongan-dong and Jungang-dong in Cheongju, one of the historic cities in South Korea. According to the acquired data from the restoration model, it is found that the construction of a new urban area during the late 1930 was resulted from the following events: the development of a railroad station located outside of the north gate of Cheongju-eup since 1921, the completion of Musimcheon embankment outside the south gate in 1932, and the construction of Chungcheongbuk provincial office outside the eastern gate in 1937. In this period of development, which the author named 'Cheongju-eup period', the streets in the old castle, consisting only of two-story financial buildings, had been expanded from the existing area at the Seongan-gil intersection to the outside the east gate of Cheongju-eup. In addition, public government buildings, which were mainly located in both Seongan-gil and Yulgok-ro in the east-west direction, were newly constructed during the late 1930s in Seokgyo-dong, a new area in which a large number of commercial buildings including department stores, clothing stores, shoes shops, and watch stores were also built along the streets. Moreover, the modern form of Cheongju-eup was to be formed by several construction projects in the area of Jungang-ro in the late 1930s. Until the 1920s, the townscape outside the northern gate of Cheongju-eup, were composed of primary, agricultural, and female schools built on a largest site of Gyoseo-ro and Daeseong-ro as well as a transportation warehouse and a railway office near the Cheongju station. Then, entering the 1930s, new school buildings and domestic industrial shops and factories were built around the area of Jungang-ro ranging from the railway outside the northern gate to Bangadari. As a result, the expansion of townscape with newly constructed buildings in the late 1930s marked the emergence of a modern form of Cheongju-eup.

Banchandeungsok is a book written by a person who lived in the Cheongju area located in northern Chungcheong Province. The literature is regarded as a useful source for showing types of local food in the 1910s, so it was purchased by the National Folk Museum in 2007. The writer categorized dishes described in the recipe section of the book into side dishes, snacks, rice cakes, drinks, and miscellaneous. Following this, each category was distinguished by the name of the dish, the main material, the side material, and the cooking method is presented in tables. Thus, the food culture of Chungcheong Province was arranged based on the above categorized contents. The material from the product and the outside which grow spontaneously divided with the product which flows. The case which is a product the outside, went through what kind of process and could flow toward Sangshin village in Cheongju area probably, to observe tried. The area and time were clear Eumsikdimibang and Gyuhapchongseo Jusigui with comparisons. So tried to observe the time of 1910's Cheongju area culture Dietary life time and a regional feature.

As part of the waterway restoration to renew traditional urban area, this paper is to assume and research Gyoseocheon(Gyoseo waterway) in Late 1960s Cheongju Korea. The main stream of Gyoseocheon flew from Sangjwagol(the head of the valley) of Uam Mt. to the north gate under Cheongju castle at first, and meandering from Sangdang Park, flew through Sudongseongdang and Bangadari Road to Musimcheon since open railroad of 1920s. This waterway, the eco-friendly figure of Gyoseocheon, that flew to inside the downtown with a planted tree and that is open space was so. The sub stream of Gyoseocheon originated in Seoundong and Tapdong were divided into two parts. One was to join the main stream of Gyoseocheon on Sangdang Park via Munhwadong, and the other was to join the sub stream of Musimcheon at northwest corner via south and west gate of Cheongju castle. This waterway as branch sewer were built into the road culvert.

This study is to seek for the reuse of vacant houses in the old settlement of urban area, focused on the Andeokbeol in Cheongju city, Korea. The following results were derived. Firstly, the maintenance and reuse methods of vacant houses are made for a number of house type as well as a variety of locational characteristics(flatland, gentle and steep slope) of the Andeokbeol. Secondly, reuse plans of vacant houses are established for a variety of classes such as local residents, artist and youth activist around cultural complex(Cheongju old cigarette factory), and outsiders. Thirdly, owners, users and intermediaries of vacant houses should find a solution to the reuse of them in company with Andeokbeol residents. And also institutional and administrative support measures are established for reuse of vacant houses.

This study is aimed to clarify the transitional characteristics of old roads and alleys lasting more than 100 years(1915-2015) in traditional urban area(Seongan-dong) of cheongju, historic inland and castle city of Korea. Cheongju castle had been completely destroyed In 1915, and urban structures been also altered last 100 years from 2015 now. Periodically, after destruction of castle, existing roads were extended and transformed to straight line for connecting with around. Expanding urban area to all directions of castle boundary in 1930-40s, town planning were created. These projects were completed in 1960-70s, the street network was built as they are. Since the 1980s, changes had been occurred in the details such as an extension of the unexecuted roads, the opening of fire lane in a block, and etc. In change and construction of roads, urban district plan in 1939 and reorganization since 1967 were planned and established with the type, location, and width of the large, medium and small roads based on data before destruction of castle. Except the width of 25m Sajikro(large3-1) and Sangdangro(large3-8,9,10), the width of 15m Namsaro(medium2-1) and Namjuro (medium2-4) as an extension of the roads, the other roads were small roads equivalent to the existing roads, and so remain intact figure of streetscape. As such, roads of east-west and north-south cross type, roads showing the outline of Cheongju castle fortress, and alleys outside the south gate are sustained in Seongan-dong of cheongju as historic urban area, and also present roads are delicately executed to the existing urban fabric.

Cheongju has been a continuously expanding city due to housing development and new town construction since the 1980s. With time, many urban problems have arisen, such as commercial decline, and degradation of the residential environment in inner city. To revitalize the inner city, this study proposed some planning strategies through the linkage of separated urban regeneration projects maximizing its effectiveness. Therefore, firstly, this study selected the target area in the inner city and identified the cause of the declination and deterioration pattern. Secondly, the main issues were derived by reviewing the locational characteristics and the potential of the target area. Finally, four strategies and detailed projects were suggested for the target area for revitalization of the inner city. Although the effectiveness cannot yet be verified due to its under realization, the results derived from the citizen's participation are having a very important impact and they can be a useful reference for similar planning.

A controller area network (CAN) receiver measures differential voltage on a bus to determine the bus level. Since 3.3V transceivers generate the same differential voltage as 5V transceivers (usually ${\geq}1.5V$), all transceivers on the bus (regardless of supply voltage) can decipher the message. In fact, the other transceivers cannot even determine or show that there is anything different about the differential voltage levels. A new CMOS RC oscillator insensitive supply voltage for clock generation in a CAN transceiver was fabricated and tested to compensate for this drawback in CAN communication. The system consists of a symmetrical circuit for voltage and current switches, two capacitors, two comparators, and an RS flip-flop. The operational principle is similar to a bistable multivibrator but the oscillation frequency can also be controlled via a bias current and reference voltage. The chip test experimental results show that oscillation frequency and power dissipation are 500 kHz and 5.48 mW, respectively at a supply voltage of 3.3 V. The chip, chip area is $0.021mm^2$, is fabricated with $0.18{\mu}m$ CMOS technology from SK hynix.
