Purpose: To report a case of verteporfin photodynamic therapy (PDT) for juxtafoveal choroidal neovascularization (CNV) secondary to angioid streaks. Case summary: An 54-year-old male presented with metamorphopsia of the right eye. It was diagnosed as juxtafoveal CNV secondary to angioid streaks and treated with verteporfin PDT-Best corrected visual acuity (BCVA) and macular thickness by optical coherence tomography (OCT) were measured. Over 14 month follow-up period, baseline BCVA was 0.3 and it increased to 0.4 by the final examination, while macular thickness decreased from 264 μm to 229 μm. No side effects of PDT were noted. Conclusions: Verteporfin PDT for CNV-associated with angioid streaks does not appear to significantly alter the course of the disease undergoing enlargement and disciform transformation of the neovascular process. However, we expected that the actual clinical findings improved during short term follow-up. The severity of symptoms of CNV-associated with angioid streaks in a single patient varies over time, so long-term follow-up and careful examination is needed.

Purpose: To evaluate the early effect of orbital reconstruction with MacroPore® by assessment of orbital volume through orbital computed tomography (CT) in cases of orbital wall fracture Methods: We performed orbital reconstruction with MacroPore® in patients with orbital wall fracture smaller than 3 cm×2 cm. Orbital CT was done preoperatively and 6 months postoperatively. We then evaluated the results by measuring the orbital volume through Rapidia 2.8 program. Results: The study comprised 14 patients. The site of fracture was the medial wall in one patient, inferior in seven, and both medial and inferior in six patients. The site of insertion of MacroPore® was the medial wall in one patient, inferior in 12, and both medial and inferior walls in one. The mean volume of the affected orbit before operation was 20.23±2.78 cm3, that of the unaffected orbit was 18.27±2.24 cm3 (p- value=0.000), and the mean volume of the affected orbit after operation was 19.06±2.57 cm3, that of the unaffected orbit was 18.06±2.24 cm3 (p-value=0.000). The mean enophthalmos before operation was 1.00±0.62 mm, and after operation was 0.64±0.46 mm. The mean difference of orbital volume between the affected and the unaffected orbits before operation was 1.96±0.33 cm3, and 1.00±0.87 cm3 after operation (p-value=0.000). The mean volume of the affected orbit before operation was 20.23±2.77 cm3, and 19.06±2.57 cm3 after operation (p-value=0.000). Each cubic centimeter decrement in volume caused a 0.67±0.68 mm mean decrease of enophthalmos. Conclusions: We concluded that MacroPore® was safe orbital implant and effective in decreasing the orbital volume at early orbital reconstruction in cases of orbital wall fracture smaller than 3 cm×2 cm through a comparison of orbital volume before and after operation.

Minimalism, which appeared in artistic circle of 1960’s, has been tendency with time gap. Critic used the term of Minimalism so that express the present situation that the only formative characters of minimal art, simplicity and clearance, became known in the world. The minimal architecture came out in the social situation of minimal tendency and in the architectural situation that complicated and inscrutable form danced widely. Corporal perception is one among several tendencies that human, disregarded in architecture since 1960’s, became important. This is closely connected with phenomenology and found in minimal art. Activation of perception is the architect’s efforts for unsettled character. This is achieved through using features of corporal perception. Dialogic character can intensify through endless excitements. So minimal architects expose just as looks change or can show factors that is changing but non-physical through perceptual activation. The purpose of this study was to analyze the housing mobility behavior according to the income change and to predict the probability of upward and downward movements. A binary logit model was used with the data which were obtained by the Korea Research Institute for Human Settlements in 1989. The sample size was 1620 households in Seoul. The results of this study were as follows; the upward movement probability in rental housing or in single housing was higher than that in owned housing or in apartment housing as household income increased.

As the Townhouse in the Block-typed Detached Housing Sites are pursuing an advanced, public space in townhouse haven't been considered than the individual gardens. But Public Exterior spaces are very important factors for Multi-family Housing Complex as community and interacting with neighborhoods. Therefore the purpose of this study is to investigate the planning aspects of townhouse, and find directions for improvement by searching for problems. For this, we have looked into the governments policy for the Block-typed Detached Housing Sites. The planning characters are divided and researched as ① Site planing ② Public Exterior planning ③ Parking planing ④ Private Exterior planning. According to the results of analysis, the attributes can be found problems due to the absence of regulations and design guidelines. Therefore this study suggests the improvement direction to exterior space planning of townhouse in new town.

This study is aimed to understand the development phase of the department stores in Seoul. We analyzed the location, zoning, scale, area and characteristics of architectural planning on 50 cases from 1970"s to present. Through these analyses we ascertained that the location, zoning and scale are related with the character’s of the site as central place and have the period division. The period division is 1) A formative period in CBD & Cheonglyanglee subcenter(1970-1979), 2) A reinforcement period of the subcenter(1979-1988), 3) A expansion period of regional center(1988-1999), 4) A reinforcement period of center place(2000-). Based on these we analysed the characteristics of architectural planning in the escalator and it"s hall, function & program and roof-garden & common space. We draw that the location & zoning is closely connected with Seoul’s urbanization and periodical conditions for central place had influence on the architectural planning of department store in Seoul.

학습관리시스템은 교수자 및 학습자에게 교육과정의 효과적 관리에서부터 학습자 간의 상호작용까지 물리적 환경에 제한 되었던 교실 수업을 온라인에서의 폭넓은 학습 환경으로 확장시켜 주는 데 중추적 역할을 해왔다. 나아가, 학습관리시스템에 사용자가 남긴 로그 데이터들을 분석하면 그들의 온라인 활동 양상을 읽을 수 있고, 분석 결과들에 기반하여 개별 학생들의 학업을 촉진시킬 수도 있다. 학습관리시스템에 존재하는 빅데이터의 활용, 적절한 데이터 마이닝 기술, 그리고 분석 결과의 시각화는 학습 분석학이라고 하는 새로운 학문 영역의 주요 관심사에 해당한다. 본 연구는 이러한 학습 분석학의 한 응용으로서 학습자의 온라인 행동 양상을 시각적으로 보여주는 대시보드를 설계하여 실제 학생들에게 적용하고 이들의 반응을 확인하고자 하였다. 자료의 수집과 분석은 크게 4가지 단계로 이루어졌다. 첫째, 국내 소재 가상캠퍼스를 활용하는 대학의 학생들을 대상으로 사전 요구조사를 실시하였고, 둘째, 이를 기반으로 설계된 대시보드의 사용성 검사를 실시하였으며, 셋째, 대학 내 중형 수업에 해당하는 서로 다른 두 개 반을 대상으로 대시보드를 제공하여 반 학기 동안 언제든지 확인할 수 있도록 하였다. 마지막으로, 학기가 종료된 후 대시보드의 사용 경험을 설문을 통해 조사하였다. 연구결과, 전반적으로 대시보드에 대한 학생들의 이해도는 높은 편 이었고, 대시보드와 실제 자신의 행동인식 간의 일치도 또한 양호한 편이었으나, 대시보드에 대한 인지된 유용성은 상대적으로 저조하게 나타났다. 또한 대시보드의 세부 항목별 이해도에 차이가 나타나서, 이러한 연구 결과를 바탕으로 대시보드를 수정하고 개선하기 위한 설계 시사점이 도출되어 향후 연구 방향과 함께 논의되었다. Learning Management System (LMS) has played important roles to support teaching and learning from the effective course management to the communication and collaboration between an instructor and students, and among students. Further, web log files that instructors and students leave in LMS not only explain their online learning patterns but also enable to provide a useful treatment and learning guidance to students. Use of big data such as the log files, technics of educational data mining (EDM) and provision of appropriate treatments throughout the visualized dashboard have been attractively recognized among researchers and practitioners who connect them with smart learning. This study includes four phases. First, we investigated how students in a large university used Moodle LMS in their virtual campus and how they perceived the needs of learning analytics dashboard. Second, based on the preliminary investigation, we designed and developed a visual dashboard presenting students’ online learning patterns. Third, we conducted a usability test in order to extract design implications for the effective dashboard. Fourth, after implementing the dashboard treatment to students, we surveyed the conformity between their perceptions and tracked online behaviors, the level of understanding, and perceived usefulness on the dashboard. While participants of this study revealed high level of understanding and fair level of conformity, their perceived usefulness was relatively lower. Throughout the survey results as well as the usability test which involved stimulated recall methods as well as interview we learned students had different levels of understanding on six major contents including total login time, login frequency, login regularity, visiting on board, time spent on board, and download of learning materials. Based on the implications from the experiment and survey results, multiple directions to improve the usefulness of dashboard were reviewed and discussed in conclusion. This study is meaningful since the developed dashboard is expected to make an advancement of LMS by adding such learning analytics dashboard in the system.

1987년~1998년 신문지면에 사용된 전생활(全生活)백화점의 지역시설로서 의미

박연정(Park, Yeon-Jeong) 한국산학기술학회 2015 한국산학기술학회논문지 Vol.16 No.12

본 연구는 1980년대 말 신문 지면에 등장한 ‘전생활백화점’의 의미를 건축적으로 이해하기 위한 것이다. 전생활백화 점은 판매 이외 생활에 필요한 다양한 프로그램과 서비스를 제공하는 백화점을 설명하기 위하여 나타난 용어이다. 단어 자 체로 보면 ‘전생활’은 전(全)과 생활(生活)의 합성어로 전체 생활을 의미하므로, 구분된 생활이 있다는 것을 전제하고 있는 것이다. 따라서 근대 이후 도시와 건축에서 생활유지를 위해 필요한 공간과 건축물 등을 분류하고 구분한 지역시설로 설명 될 수 있을 것이라 생각하였고, 이를 바탕으로 지역시설로 ‘전생활백화점’을 이해해 보고자 하였다. 지역시설의 구분체계에 서 일반적으로 백화점은 3차(광역) 생활권의 시설이다. 하지만 용어가 등장한 당시 백화점의 입지와 프로그램분석을 통해 백화점이 아파트단지를 중심으로 일상생활범위 내에 위치하고 아파트에 거주하는 그들의 일상생활을 위한 공간들을 포함하 고 있었음을 확인하였다. 즉 전생활의 전(全)은 1차, 2차 생활, 3차 생활의 전체를 의미하는 것으로 이해할 수 있으며, 입지적 으로는 1차생활권에 위치한 3차생활 지역시설이었다. 이러한 특수한 백화점은 현재까지도 유효하기에 유의미하며 더 이상 전생활백화점이라는 용어는 별도로 사용하지 않는다. The purpose of this study is to clarify the architectural meaning of the term 'Whole life Department Store' that appeared in newspapers' in the 1980s. A term of 'Whole Life Department Store' is appeared to explain the emergence of department stores, including the space for a wide range of programs and services they need to live, as well as sales. This word, "Whole life", is a compound of the Whole(全) and Life(生活) and word means the entire life. This will assume that you are separated life. So I was thinking that it could be described as regional facilities that classify and distinguish the necessary space for living and building maintenance, etc. in city and architecture since the modern. And Based on this, I would understand the whole life department as regional facilities. Generally a department store is a regional facilities for higher level living area. I analyzed the location and program of department stores at the time of the emergence of the term. Through this analysis department store was located in the daily range around the apartment complex and contained spaces for the daily life of the inhabitants apartment complex. It is significant in this particular department to be valid today and the term of 'Whole Life' department store is not longer used.

박연정(Park, Yeon-Jeong),유해연(Yoo, Hae-Yeon) 대한건축학회 2017 대한건축학회 학술발표대회 논문집 Vol.37 No.1

The purpose of this study is to analyze the characteristics of housing type in the Haengchon district, which was one of the target areas for castle town renewal projects conducted by the Seoul Metropolitan Government to preserve and protect the residential area around the castle along with the promotion of the Seoul City Wall’s UNESCO inclusion. In the process of recording the life culture of the village, which was carried out in order to establish the rehabilitation plan, it was recognized that the village has various types of houses. The analysis of this is not only to understand the history of the village, It is considered that it can be a major factor in establishment. Therefore, the typology and characteristics of the housing in the rural area were studied. Through the study, it was found that the change of the street had a great effect on the housing type. Especially, since the types of these houses are blocked, it is considered that if different plans can be established in the future, it will be possible to continue to be a healthier village if different plans can be established.
