The majority of Apartment in Korea were supplied massively constructing new town in the mid 80s. The apartment houses constructed during this time are rapidly becoming obsolete. Furthermore, it is predicted that the necessity and revitalization of remodeling apartments will increase in the future. This study is aimed to analyze the remodeling planning factors of the deteriorated apartment houses and selecting priorities as a type of urban regeneration. For consumer focused remodeling, I have investigated remodeling planning factors and selecting priorities, and managed to present political subjects and directions to revitalization of remodeling apartments. This study has divided the interested parties related to the remodeling apartment house project into 4 different categories; residents, public institutions, private enterprises, academic community. And these 4 subcategories have been compared and analyzed their respective priorities in regards to remodeling planning factor of the deteriorated apartment house. The first priority of residents and private enterprises is economic feasibility. This differs from public institutions and the academic community’s preference of stability. These parties had wide gaps in regards to their second priority. Residents and private enterprises choose stability, while public institutions sway towards space application, and the academic community tends to choose the overall publicness of a building. It has derived the result reflected the importance and the priority of remodeling planning factor each interested parties considers. Stability was the first priority, followed by economic feasibility, space application, and publicness. The aggregate of these results have a significant influence into the required material necessary for future remodeling apartment projects.

We propose a universal spintronic logic device based on the current-induced magnetic domain wall (DW) motion. The majority gating operation is demonstrated by micromagnetic simulation using spin-orbit torque (SOT)-driven DW motion in Hall bar structures with perpendicular magnetic anisotropy. The logic gates including AND, OR, NAND, NOR are demonstrated, indicating the universality of DW majority gate. The simulation is partially confirmed by experiment, in which we found that the asymmetry in DW motion induced by Dzyaloshinskii-Moriya interaction or local Oersted field can cause the device malfunction. Our result suggests that the DW motion can be used not only in memory device but also in logic device, which could be useful in future processing-in-memory computing technology.

Background : Punctuation marks are a visual symbol that effectively convey the content and meaning of a text, fulfilling the same typographic role as type on the printed page. Punctuation marks are a unique point in modern visual culture, which is changing from a reading culture to a print culture. This study examin punctuation marks, which have only been studied for their usage in the field of national literature, from a functional and visual design perspective. Methods : This study presented typographic features by collecting and characterizing all punctuation marks used in 22 issues of ‘So Nyun’, the first general magazine of modern periods in Korea. 24 types of punctuation marks that were continually used were collected from ‘So Nyun’, and they were grouped into three categories based on function and usage. Additionally, the characteristics of each of the three categories were presented. Results : Choi Nam-sun tried to preach modernity not only through content but also through visual layout through ‘So Nyun’. The three categories of use of punctuation marks revealed in ‘So Nyun’ resulted in use for classification of information, use for highlighting information, and creation of visuality. ‘So Nyun’ visually shows modern characteristics through the use of experimental yet universal punctuation marks, which can be said to be a model of modern writing. Conclusions : By analyzing the typographic characteristics of ‘So Nyun’ with a focus on punctuation marks and presenting their significance, the design modernity revealed in ‘So Nyun’ is raised. By recognizing Choi Nam-sun as a modern designer through the usage of Punctuation Marks based on experimentation and universality, this study aim to expand the scope of Korean design research into the modern period.

Since the 1990s, the second generation of Zirconium alloys containing main alloy compositions of Nb, Sn and Fe have been used as a replacement of Zircaloy-4 (Zr-Sn-Fe-Cr), a first-generation Zirconium alloy, to meet severe and rigorous reactor operating conditions characterized by high-burn-up, high-power and high-pH operations. In this study, the mechanical properties and creep behaviors of Zr-Sn-Fe-Cr and Zr-Nb-Sn-Fe alloys were investigated in a temperature range of $450{\sim}500^{\circ}C$ and in a stress range of $80{\sim}150\;MPa$. The mechanical testing results indicate that the yield and tensile strengths of the Zr-Nb-Sn-Fe alloy are slightly higher compared to those of Zr-Sn-Fe-Cr. This can be explained by the second phase strengthening of the $\beta$-Nb precipitates. The creep test results indicate that the stress exponent for the steady-state creep rate decreases with the increase in the applied stress. However, the stress exponent of the Zr-Sn-Fe-Cr alloy is lower than that of the Zr-Nb-Sn-Fe alloy in a relatively high stress range, whereas the creep activation energy of the former is slightly higher than that of the latter. This can be explained by the dynamic deformation aging effect caused by the interaction of dislocations with Sn substitutional atoms. A higher Sn content leads to a lower stress exponent value and higher creep activation energy.

This paper entirely explains the Korean astronaut program from astronaut selection to launch and return and introduces technology and results through this program in detail. The Korean astronaut program launched Nov. 2005 with the objectives to develop the manned space technology such as astronaut selection, training and space experiment and to disseminate concerns to the public about the science and space. In 2006 to select the Korean astronauts, the standards for selecting astronauts were set and then the selection processes from 1st stage to 4th stage were performed. In 2007, the 2 Korean astronauts took the astronaut training and the 18 domestic science experiments and 3 international experiments which the Korean astronaut, Dr. Yi, performed in ISS last April were developed. In April 2008, the Korean astronaut was transported to ISS by Soyuz in Baikonur in Kazakhstan and returned to the ground with performing the mission and space experiments. This paper will explain these processes as the above(astronaut's selection, training, space experiment, etc.) in detail.
