Students recognize illustrations before letters when they look at textbooks. Students find some illustrations difficult to understand, not because there is something wrong with the illustration itself but because information has not been provided or presented in an effective way. For this reason, Illustrations are very important for students to build up the concepts of what they are learning. For the purpose of the study, we have made 12 questions with selected 9 illustrations included in Information and Communication unit of the Physics Ⅰ textbooks according to the revised national curriculum in 2009 and Advancing Physics of UK and then we conducted a survey with 360 students of high school and 22 teachers of science. This study intends to recognition the contents of physicsⅠ textbooks, focusing on the chapter of Information and Communication. For this, a questionnaire on the three types of illustrations was prepared to find out what kind of illustration students thought was easy to understand and why they chose it. Based on the answers to the questionnaire, the conditions for clear and effective communication of textbook information through illustrations were found, by analyzing the advantages and disadvantages of some types of illustrations. In this study, illustrations students thought difficult were picked out be easier and clearer to understand to see which of them are more helpful for students. The features of illustrations easy for students to understand well are as follows: First, the essence of improving illustrations is that the contents should be concise and brief in order not to confuse students. The the illustration should also include each step of the process through which the result was achieved, instead of simply showing the result. Second, the illustration should not be difficult to externally visible; When high school students feel frustrated while trying to understand the illustration, they tend to give up rather than ponder more to get to the meaning. Third, no matter how difficult illustrations are, some good clues and explanations about them make students try to understand what they mean positively rather than lose interest.

서주옥,이성창,김도년 한국도시설계학회 2020 도시설계 : 한국도시설계학회지 Vol.21 No.4

This study aims to propose a public housing reconstruction model that differs from private housing reconstruction, by exploring different reconstruction measures, selecting pilot project complexes, and presenting an outline reconstruction plan. To this end, this research suggests that a circular approach be applied to reconstruction at the local community level to enhance the resettlement of existing tenants in terms of a ensuring base for living, regulations on zoning and other issues be eased to allow for the provision of additional new housing, average citizens be allowed to access these residences, and facilities be built inside the public housing complexes as infrastructure to support people’s daily lives and establish strong centers for local communities. Seventeen of the thirty-four complexes owned by Seoul Housing & Communities Corporation that are due for reconstruction within the next five years are categorized into three reconstruction types: utilizing existing state-owned housing, utilizing government-owned housing sites in the vicinity, and utilizing idle sites within the complex. This paper proves that the reconstruction plans covering the Sanggye-Madeul Complex, the Seongsan Complex, and the Bangwha Complex 11 are feasible with the circular approach to rental housing reconstruction, including (1)easing of zoning regulations, (2)adopting the concept of government-subsidized housing, and (3)attracting infrastructure investment from the private sector. 본 연구의 목적은 서울시 공공임대주택 단지의 재건축 방안을 모색하기 위해 시범단지를 선정하고 개략적인 재건축 계획을 통해 민간과는 차별화되는 공공임대주택 재건축 모델을 제시하고자 한다. 이를 위해 생활권 단위의 순환형 재건축을 통해 기존 생활기반에서 거주자 재정착을제고하고, 용도지역 상향 등 규제 완화를 통해 신규 주택을 추가 공급하는 것으로 계획했다. 추가 공급주택들은 서민계층까지 입주를 확대하고 단지시설은 생활SOC시설로 조성하여 지역 거점화하는 방안을 제시했다. 단지특성에 따라 재건축 유형을 ‘공공 보유주택 활용형’, ‘인근 공공부지 활용형’, ‘단지내 유휴부지 활용형’ 3가지로 개발하였고 서울주택도시공사 소유의 34개단지 중 5년내 재건축 연한이 도래하는 17개 단지를 유형별로 분류하였다. 이 중 상계마들단지, 성산단지, 방화11단지를 시범단지로 선정하였고 생활권 단위의 순환형 재건축을 원칙으로 ①용도지역 상향, ②사회주택 도입, ③생활SOC시설조성을 전제로 계획하여 공공임대주택 재건축이가능함을 입증했다.

서울시 대중교통 이용현황과 비주거 용도지역의 비교분석을 통해 본 도시계획 실효성 검증 연구

서주옥(Suh, Ju Ok),김도년(Kim, Do Nyun),이성창(Lee, Seong Chang) 한국도시설계학회 2019 도시설계 : 한국도시설계학회지 Vol.20 No.3

본 연구는 대중교통 이용현황과 비주거 용도지역의 분포를 비교 · 분석하여, 중심기능을 수행하도록 계획한 비주거 용도지역에서 그에 상응하는 도시활동이 일어나는지를 검증하고자 한다. 이에 대표적 대중교통인 지하철과 버스의 이용현황과 패턴을 분석하여 두 교통수단간의 특성을 검토하고, 그에 따라 대중교통 이용량이 높고, 출근시간대 하차, 퇴근시간때 승차인원이 높은 지역을 대중교통 중심지로 선정하였다. 업무, 상업 등의 중심기능 도입이 가능한 상업지역, 준공업지역, 준주거지역을 비주거 용도지역으로 설정하여 대중교통 중심지와 일치여부를 비교 · 분석하였고 그 원인을 파악하였다. 대중교통 중심지와 비주거 용도지역은 대체적으로 일치했으나 비주거 용도지역임에도 불구하고 대중교통 중심지가 위치하지 않는 지역은 불광 · 응암, 천호 · 길동, 구의 · 자양, 신림 · 봉천 등으로 이 지역들은 계획적으로 중심지로 육성하고자 했으나 중심지로 성장하지 못했음을 알 수 있다. 비주거 용도지역은 아니었으나 버스 이용중심지인 공릉2동과 대학동은 대학교가 위치하여 대중교통 이용률이 높음을 알 수 있다. 종합하면 용도지역이 중심지를 계획 · 관리하는 수단 중 하나로 중심지 육성의 기반을 제공할 수는 있으나 실질적으로는 그에 상응하는 도시 활동, 인간 활동이 수반되어야 중심지가 형성됨을 알 수 있다. This study aims to examine the effectiveness of land use zoning by assuming that areas with high traffic volumes with public transportation service may be active urban centers. We analyzed use patterns of subway trains and buses, and reviewed the characteristics of both major means of public transportation. Following this, the data was analyzed to look for areas where there is considerable usage of public transits as well as specifically locate active zones with high population flow during rush hours. To prove the effectiveness of land use zoning, we collectively defined commercial, semi-industrial and semi-residential districts as non-residential areas where business and commercial activities are their major functions. We analyzed and compared those areas with active urban centers to find overlapping regions and hypothesized reasons for when there were no overlaps. We found that active urban centers coincided overall with non-residential areas. We also noted that, towns such as Bulgwang · Eungam, Cheonho · Gil, Guui · Jayang and Sillim · Bongcheon, where there were no active urban centers despite being non-residential areas, were originally planned to be developed into urban centers according to local urban planning, showing failure in achieving the goal set out during planning. Despite not being considered non-residential areas, Gongneung-2-dong and Daehak-dong have been embracing universities and have high densities of commuters using buses around their regions. In summary, though land use zoning may provide a framework for developing urban centers and be a means of designing and managing new urban centers, results indicate that areas should be accompanied by corresponding human activity to grow into urban centers.

건축물 연면적 현황과 도시기본계획의 중심지와의 비교 분석을 통한 물리적 중심지 검증 연구

서주옥(Suh, Juok),김도년(Kim, Donyun),이성창(Lee, Seongchang) 한국도시설계학회 2017 도시설계 : 한국도시설계학회지 Vol.18 No.1

본 연구는 서울의 도시기본계획인 ‘2030서울플랜’이 2014년에 확정ㆍ고시됨에 도시기본계획의 물리적 계획인 중심지계획에 따라 중심지가 재대로 관리ㆍ육성되는지를 검증하고, 중심지 형성요인을 파악하여 향후 계획시 검토방향을 제시하는 것이 목적이다. 중심지는 기존 시가지에 중심지를 지정하는 방식과 신규개발지에 중심지를 지정하는 방식으로 구분할 수 있다. 신규개발 중심지는 상암, 문정을 들 수 있으며 이들은 공공주도 사업으로 조성되어 10~20년 내에 물리적인 변화가 나타났다. 기존 시가지를 중심지로 지정한 경우는 청량리ㆍ왕십리, 창동상계, 미아 등으로 성장가능성 등을 고려하여 지정했음에도 불구하고 물리적인 변화가 나타나지 않았다. 이외에도 도시기본계획상 중심지가 아님에도 자생적으로 성장하여 중심지를 형성한 신사, 서초, 양재, 동대문이 있다. 이들은 대부분 상업용도의 비율이 높은 지역으로 관광객 등이 유동인구가 많아 도시가 자생적으로 변모한 경우이다. 이를 통해 중심지를 형성하는 요인을 살펴보면 신규개발지는 도시계획적 수단이 매우 효과적인 것으로 나타났고, 기존 시가지는 도시계획적인 수단보다는 집객이나 도시활동 등이 중심지 형성에 더 많은 영향을 끼치는 것으로 나타났다. 이와 같이 지역의 성격에 따라 그에 적합한 중심지계획을 수립하여야 할 것이다. According to the confirmation and notification of ‘2030 Seoul Plan’ in 2014, this study aims to examine the current status of the urban centers and build up the framework for future plan based on the factors forming the urban center. The urban centers were categorized based on the realization of plan and purpose of designation. The findings for this study are as followed: newly-developed centers such as Sangam, MunJung have been greatly changed in urban environment for the last 10-20 years by public development projects. In the case of designating the existing city area as the urban center, the physical change did not occur even though the designation was made considering the possibility of growth as Cheongryangri/Wangsinri, Changdong Sanggye and Mia. Though these centers had growth potential, there has no physical changes noticeably. Yangjae, Seocho, Shinsa, Dongdaemun, etc. are not the urban centers of Seoul urban basic planing have experienced substantial growth with high agglomeration of neighborhood commercial facilities and a large floating population. The principal influencing factors to form urban center are urban policy or city planning for newly-developed areas. The growth of urban centers in old city, on the other hand, are influenced by visitor attraction factors, urban activities, etc. The findings suggest that considering the characteristics of urban center is a key factor for effective urban planning.

Many public rental housings which have been supplied since 1989 in Seoul are confronting the stage for remodeling. ‘Act on the Support for Improving the Quality of Lives of Tenants in Long-Term Public Rental Housing’ enacted in March 2009 enabled to establish the systematic basis for the remodeling of public rental housing. Thus, this study aims to develop design elements for the remodeling for the long-term public rental housing in Seoul. The subject of this study is 23 complexes of long-term public rental housing which are located in Seoul and managed by SH. This study proposes three strategies for the remodeling of long-term public rental housing : improvement of settlement environment considering resident characteristics, improvement of negative image by planning better facade and open housing complex, implementation of ‘Low-cost and High-efficiency’ strategies on existing long-term public rental housing. It is recommended that further study to establish systematic basis such as the precise and synthesized examination system and financial scheme to support the remodeling of long-term public rental housing.
