This study estimated the number of semi-basement households in Seoul and evaluated their flood vulnerability at the administrative dong level, taking various factors into consideration. Vulnerability assessment indicators, including the percentages of semi-basement households, were selected based on previous studies and consisted of a total of 26 indicators, considering exposure, sensitivity, and adaptability. Social, economic, environmental, and integrated flood vulnerability were all considered in multidimensional evaluation of both flood vulnerability and the multidimensionality of damage. Vulnerability assessment was conducted by calculating and evaluating vulnerability for each dimension. Subsequently, integrated flood vulnerability was assessed by summing the values of the social, economic, and environmental categories and interpreted in comparison to flood inundation maps. The evaluation results showed that in all vulnerability categories, more than half of the administrative dongs in Seoul exhibited high vulnerability. For social flood vulnerability, in particular, the highest number of administrative dongs had a "very high" rating among the four vulnerability categories, indicating a significant potential for population and social system damage in the event of a flood. Additionally, integrated flood vulnerability exhibited very high results in Seoul's southwestern and northeastern areas. These study findings are expected to contribute to region-specific flood response and policy prioritization aimed at reducing semi-basement dwelling damage. Furthermore, identifying the number of semi-basement households in Seoul and demonstrating their societal flood vulnerability can be utilized as valuable data for the purpose of reducing damage to such households.

Fine dust is one of the most critical environmental issues in Korea, and the government recognizes the need to establish customized reduction policies based on regional characteristics. Several studies on air pollutants investigate whether factories affect the distribution of fine dust in a particular region. However, understanding the impact of the entire industry sector requires further investigation. This study identifies the impacts of industrial characteristics on fine dust levels of 141 municipalities across Korea in 2016. A total of 23 variables were used, of which 12 referred to industries and 11 to general characteristics of each city. Due to the high correlation between independent variables, partial least squares (PLS) regression models were used. The analysis identified 14 significant variables for PM10 and 13 for PM2.5. Therefore, the results suggest that local industrial characteristics can significantly influence fine dust levels and provide suggestions for establishing customized reduction policies based on local characteristics.

음정현,채정민,피재환,이성민,최균,김상진,홍태식,황충호,안학준,Eum, Jung-Hyun,Chae, Jung-Min,Pee, Jae-Hwan,Lee, Sung-Min,Choi, Kyoon,Kim, Sang-Jin,Hong, Tae-Sik,Hwang, Choong-Ho,Ahn, Hak-Joon 한국결정성장학회 2010 한국결정성장학회지 Vol.20 No.2

플라즈마 에쳐 내에 사용되는 실리콘 전극과 링 부품은 사용 중에 강한 플라즈마와 접촉하면서 주기적인 가열과 냉각 과정을 거친다. 이 때 부품의 표면에서는 열 응력으로 인하여 PSB라고 하는 띠 형상의 결함이 생성되며 이로 인하여 그 수명을 다하게 된다. 원료인 실리콘 잉곳의 관점에서 그 수명에 미치는 인자를 살펴보았다. 잉곳의 등급, 즉 S/F와 S/A에 따라 불순물과 결함의 농도를 GDMS와 ${\mu}$-PCD로 평가하여 잉곳의 어떤 요소들에 의하여 수명이 결정되는가를 분석하였다. 그 결과, {001} 면상에서 관찰되는 <110> 방향의 면 결함들이 PSB와 연결될 가능성이 있음을 제안하였다. Silicon electrode and ring in a plasma etcher those are in contact with harsh plasma suffer from periodic heating and cooling during their lifetime. This causes the silicon components failure due to thermal stress remaining the persistent slip bands (PSBs) on their surfaces. The factors that determine the lifetime of silicon electrode and ring were discussed with respect to silicon ingot. The impurity level and the average defect concentration measured with glow discharge mass spectrometer (GDMS) and microwave photo-conductance decay (${\mu}$-PCD) were compared with the grade of silicon ingots those are divided to slip-free and slip-allowed ingot. Some silp-allowed samples showed planar defects along <110> direction on {001} surface. The role of these defects was suggested from the viewpoint of the lifetime of silicon components.

This study aims at understanding the evolved trends and expressive features of Korean fashion styling in fashion journals for the recent 3 years and finding out possibilities of Korean fashion to spread throughout the world stage based on this. Findings of research are as follows: There were 34 Korean illustrated magazines which were selected according to standards of Korean images established based on precedent studies, and a total of photos with more than 320 cuts were chosen. For Korean illustrated magazines, more than half of selected illustrated magazines appeared in 2012 when Korean issues were stressed more than before, and many of them appeared in January and May due to seasonal influence by month. For the tendency of Korean illustrated magazines appeared after the year of 2010, expressive methods became more various than those of the past, and many factors were mixed with each other as well. Illustrated magazines were designed and shown along with various intentions rather than simply showing something Korean. In addition, for expressive methods of the recent Korean illustrated magazines, expressions of Korean retro styles, expressions of mixed images, and expressions of various Korean themes. As mentioned above, we expect that studying illustrated magazine styling which is sensitive to trends will provide a opportunity to give a new boost by widening the scope of Korean fashion image research to pursue globalization.

Cost-effective purification methods of silicon were carried out in order to replace the conventional Siemens method for solar grade silicon. Firstly, acid leaching which is a hydrometallurgical process was preceded with grinded silicon powders of metallurgical grade (~99% purity) to remove metallic impurities. Then, plasma treatments were performed with the leached silicon powders of 99.94% purity by argon plasma at 30 kW power under atmospheric pressure. Plasma treatment was specifically efficient for removing Zr, Y, and P but not for Al and B. Another purification step by EB treatment was also studied for the 99.92% silicon lump which resulted in the fast removal of boron and aluminum. That means the two methods are effective alternative tools for removing the doping elements like boron and phosphor.
