This paper, based on "Minhwa Chaekgeori" paintings from the collection of the National Museum of Korea, identifies and discusses fourteen similar works in domestic and international collections as products of the Seokdang workshop. First, the relevant paintings are identified as products of the workshop known as Seokdang (石堂, literally "stone hall") by the workshop's seal that is stamped on them. Second, analysis of the iconography indicates that the paintings were likely produced in the 1920s. Third, research on certain geographic names and addresses associated with this group of paintings suggests that they might not have been separately commissioned, but are rather examples of partially "ready-made" paintings. Fourth, the paper discusses how the designs of various cultural products in these paintings reflects contemporaneous changes in Korea's diplomatic and commercial relations, i.e., the decline of relations with China and rise of relations with the United States and Europe. Finally, a comparison of the Seokdang chaekgeori paintings with the popular chaekgeori paintings produced by Yi Hyeongrok and Yi Deokyeong in the early twentieth century provides important implications for the succession of tradition and innovation in visual culture.

Meanwhile the service of public health are being improved and the patient-friendly medical environment is constructed due to the development of the medical industry, we need to take more concern for child patient's pain undergoing this change of the medical environment. Currently, pain of child patient is treated by both pharmacologic and non-pharmacologic method. The application of virtual reality(VR) is emerging as a kind of attention-conversion therapy among non-pharmacologic method both at home and abroad. This study has examined and analyzed the development cases and related studies of VR among the world. And derived 'Presence', 'Interactivity', 'Social Interaction', 'Customization', 'Embodiment' as characteristics to be considered in the clinical application of VR for children. Based on this, six measures are proposed to promote VR contents to reduce pain of child patient.

It is very important to study on the structural behaviors of structurally damaged tunnel linings. A series of centrifuge model tests were performed in order to investigate different behaviors of tunnel linings. A 1/100-scaled aluminum horseshoe tunnel linings with a radius 5 cm, height 8 cm were buried in a depth with dry Joomunjin standard sand, the relative density of which was 86%. Such sectional forces as bending moments and thrusts along the tunnel circumference were measured by twelve strain gages. Earth pressures in soil mass and on the outside of lining model were estimated by pressure transducers, ground surface settlements at a center and edges by using LVDTs.

Though old generation criticizes on costume play that it is accepted by young generation without any criticism, it is gaining popularity and is settled with unique Korean characteristics. The study is to understand the characteristics of costume play and investigate on the attitude of costume players enjoying it. For this study, a survey was conducted on costume players who order tailor-made costumes or rent them by using references, existing papers and internet sites. The results are as follows. 1.37% of costume players live in Seoul and Gyeonggi area, 37% in Gyeongsang-do and Busan with 21% in other areas. Two areas shows higher rate than any other regions, as Seoul Comic and Busan Comic are held regularly and there are faster exchange with Japanese culture in these areas with enough money 2. Among costume players, female accounts for 73.7% with 26.3% male. It shows that female likes costume play more than male. It is because woman responds actively to what she likes than man does. The number of male is steadily increasing. By age, high school student is 40%, middle school student is 36%, older than 20 is 16% with 3% of elementary school student. 3.61% of them like the reproduction of character costumes, 14.7% like Pancos and another 14.7% likethe reproduction of character costumes and creation. 69.5% participates in costume play both in groups and individuals, 26.3% in groups and 4.2% in individuals. 45.3% participates in comic more than 8 times in a yew, 43.2%, 1-2 times and 11.6%, 3-4 times. Mostly they want $50,000{\sim}80,000$ won costume. 4. on the criticism of old generation that costume play is nothing but the imitation of Japanese culture, 87.4% of the respondents answered 'absolutely not' They think costume play is one of their favorite cultures. 5. on the parents response to costumeplay, 87% of the respondents answered 'Ethey understand', 13% said 'they cannot understand and dissent'.

The purpose of this research is to propose a system to detect a strip defect on a iron plate using an image processing, one way of finding defects on an iron plate. An existing way of image processing is using a light source which release a light energy in a certain frequency and a light absorbing display which responds to the light source. This research attempts to detect defects by using a image processing and multi-Tread which handles an illumination, without depending on characteristics of light frequency. One of the advantages of this method is that it makes up for the weakness of the existing method which was too difficult for users to notice a defect. Also this method makes it possible to realize a real-time monitoring on a plate of iron. The other advantage of this method is that it reduces the price of hardwares on demand to match the frequency of light emitting display and light absorbing display because this method only needs a hardware which is easy to buy in any market.

This study aims to conduct research into the property of costumeplay that has been established with our unique characteristics despite the critics from the existing generation, and the cospre style preferred by costumeplayers. The research methods include literature study, existing research, and a survey targeting costumeplayers who make costumes upon order or borrow costumes on websites. The findings are as follows. 1. From the results of the survey, 77% of the participants in the costumeplay were secondary school students, 16% were college students, and 5% were primary school students. 2. The distribution of the residences of the costumeplayers was found to be mostly centered in two areas including Seoul/Gyeonggi and Gyeongsang/Busan, which were 39% and 37% each. This is probably because Seoul Comic and Busan Comic were regularly taking place, and these are relatively economically affluent areas and locations where the rapid exchange of Japanese culture occurs. 3. For the cospre style preferred by costumeplayers, 57% of respondents preferred costumes for reviving characters, 18% of them for fan-cospre and 14% of them for reviving a character and creating new characters. Costumeplayers preferred cospre costumes for reviving characters rather than for creating new characters. 4. Most respondents preferred a character-oriented design, posting 31.9%. Next, 17.5% of them selected the Lolita look This is probably because the Lolita look which is much favored in the latest fashion trends affects them, and the rest of the respondents preferred a fantasy/SF group, visual, uniform, and maid look, in order. 5. For costs required for costumeplay for 1 time, 39% of respondents spent about KRW $100,000{\sim}150,000$, and 24% of them about KRW $150,000{\sim}200,000$. However, for buying accessories or small items, over 50% of them spent KRW $30,000{\sim}40,000$.

The construction industry is heavily dependent on labor force as automation to building constructions is difficult due to its characteristics such on-site production, custom manufacturing production. Thus, while securing and fostering high-quality functional manpower for stable construction work are significant, the construction workforce has been persistently lacking compared to demand. Young workers are reluctant to enter the construction industry due to high labor intensity, unstable employment structure, and uncertainty for the future. The employment rate for new jobs in the construction industry is half as high as in others. Currently, the departments related to construction are organized in specialized high school to conduct training for young workers. The graduates have a low ratio of employment rate to the construction industry and functional capacities fallen short of expectations. In this study, the education and training conditions of specialized high schools were analyzed to derive problems and key improvements of the education system were drawn. As an improvement for the analysis results, it provides solutions such as giving advantages of previous education experience, expand industry-academic cooperation with businesses, and expand links with external educational institutions.

올해도 어김없이 발렌타인데이가 지났다. 매년 반복되는 발렌타인데이 풍속에 대해 초콜릿을 앞세운 얕은 상술에 불과하다는 시각이 지배적이긴 하지만, 요즘 연인들은 이런 날조차도 멋지게 자신들의 것으로 만들어 내는 센스를 갖추고 있다. 각종 초콜릿 재료와 아기자기한 포장 장식을 사서 직접 초콜릿을 제작, 정성이 가득 담긴 이벤트를 마련하는 기회로 활용하는 부류가 점차 늘고 있다. 어느 누구도 아닌 바로 ‘내’가 사랑하는 사람에게 줄 선물이기 때문에 나만의 초콜릿 선물을 만든다는 것이다. 이러한 문화는 생활 곳곳에서 발견할 수 있다. 목걸이에도 자신 혹은 연인의 이니셜을 숨김없이 드러내는 제품이 나온다. 맞춤 와이셔츠를 주문하고 소매 깃에 자신의 이름을 새기기도 한다. 시장의 한 축은 대중적인 명품을 추구하는 ‘매스티지(Masstige)’를 향하고 있지만, 그 속에서 사람들은 ‘나’만의 특별한 무언가를 찾고자 한다. 이번호에서는 한창 웹상에서 대두되고 있는 ‘개인화’에 대한 이야기와, 이에 대한 모바일에서의 개인화이야기를 다루려고한다.
