This study was carried out to explore the 4th Industrial Revolution technology from the perspective of the landscape industry to provide the basic data necessary to increase the virtuous circle value. The 4th Industrial Revolution, the characteristics of the landscape industry and urban regeneration were considered and the methodology was established and studied including the technical classification system suitable for systematic research, which was selected as a framework. First, the 4th Industrial Revolution technology based on digital data was selected, which could be utilized to increase the value of the virtuous circle for the landscape industry. From ‘Element Technology Level’, and ‘Core Technology’ such as the Internet of Things, Cloud Computing, Big Data, Artificial Intelligence, Robot, ‘Peripheral Technology’, Virtual or Augmented Reality, Drones, 3D․4D Printing, and 3D Scanning were highlighted as the 4th Industrial Revolution technology. It has been shown that it is possible to increase the value of the virtuous circle when applied at the ‘Trend Level’, in particular to the landscape industry. The ‘System Level’ was analyzed as a general-purpose technology, and based on the platform, the level of element technology(computers, and smart devices) was systematically interconnected, and illuminated with the 4th Industrial Revolution technology based on digital data. The application of the ‘Trend Level’ specific to the landscape industry has been shown to be an effective technology for increasing the virtuous circle values. It is possible to realize all synergistic effects and implementation of the proposed method at the trend level applying the element technology level. Smart gardens, smart parks, etc. have been analyzed to the level they should pursue. It was judged that Smart City, Smart Home, Smart Farm, and Precision Agriculture, Smart Tourism, and Smart Health Care could be highly linked through the collaboration among technologies in adjacent areas at the Trend Level. Additionally, various utilization measures of related technology applied at the Trend Level were highlighted in the process of urban regeneration, public service space creation, maintenance, and public service. In other words, with the realization of ubiquitous computing, Hyper-Connectivity, Hyper-Reality, Hyper-Intelligence, and Hyper-Convergence were proposed, reflecting the basic characteristics of digital technology in the landscape industry can be achieved. It was analyzed that the landscaping industry was effectively accommodating and coordinating with the needs of new characters, education and consulting, as well as existing tasks, even when participating in urban regeneration projects. In particular, it has been shown that the overall landscaping area is effective in increasing the virtuous circle value when it systems the related technology at the trend level by linking maintenance with strategic bridgehead. This is because the industrial structure is effective in distributing data and information produced from various channels. Subsequent research, such as demonstrating the fusion of the 4th Industrial Revolution technology based on the use of digital data in creation, maintenance, and service of actual landscape space is necessary. 본 연구는 조경산업의 관점에서 4차 산업혁명 기술을 탐색하여, 선순환적 가치증대에 필요한 기초자료를 제공하고자 수행하였다. 4차 산업혁명, 조경산업과 도시재생의 특성 등을 고찰하고, 체계적 연구에 적합한 기술 분류 체계를 틀로 선정하는 등 방법론을 설정하여 연구하였다. 먼저, 조경산업의 선순환적 가치증대에 활용이 가능한 디지털 데이터 기반의 4차 산업혁명 기술을 선별하였다. ‘요소기술 수준’에서 ‘핵심기술’인 사물인터넷, 클라우드 컴퓨팅, 빅데이터, 인공지능, 로봇, ‘주변기술’인 가상․증강현실, 드론, 3D․4D 프린팅, 3D 스캐닝이 디지털 데이터 기반의 4차 산업혁명 기술로 조명되었다. 조경산업에 특화하여 ‘트렌드 수준’으로 응용하면 선순환적 가치증대에 활용이 가능한 것으로 나타났다. ‘시스템 수준’은 하나의 범용기술로 분석하였으며, 플랫폼을 중심으로 요소기술 수준, 컴퓨터와 스마트기기 등이 유기적으로 상호연계되어 시스템화된 디지털 데이터 기반의 4차 산업혁명 기술로 조명되었다. 조경산업에 특화하여 ‘트렌드 수준’으로 응용하면 선순환적 가치증대에 효과적인 기술로 나타났다. 요소기술 수준을 응용한 트렌드 수준에서 제시된 모든 활용 방안의 구현과 시너지효과 창출이 가능하다. 스마트정원, 스마트공원 등이 추구해야 하는 수준으로 분석되었다. 트렌드 수준의 인접산업 기술 중에는 스마트시티, 스마트홈, 스마트팜 및 정밀농업, 스마트관광, 스마트헬스케어가 협업에 의한 연계성이 클 것으로 판단되었다. 다음으로, 도시재생 공공공간을 포함한 조경공간의 조성․유지관리 및 서비스에서 도구이자 소재로서, 트렌드 수준으로 응용된 관련 기술의 다양한 활용 방안이 조명되었다. 즉, 유비쿼터스 컴퓨팅의 실현으로 조경공간에서 디지털 기술의 기본적 특성이 반영된 초연결화, 초실감화, 초지능화, 초융합화되는 방안들이 제시되었다. 조경산업이 도시재생 사업에 참여함에 있어서도, 기존 업무를 비롯하여 새로운 성격의 요구 수용 및 조율, 교육, 컨설팅 등에서 가치를 증대하는데 효과적인 것으로 분석되었다. 특히, 조경영역 전반이 전략적 교두보로 유지관리를 연계하여, 트렌드 수준의 관련 기술을 시스템화할 때 선순환적 가치증대에 효과적인 것으로 나타났다. 산업구조 상, 다양한 경로에서 생산된 데이터와 정보를 유통시키는데 효과적이기 때문이다. 향후 디지털 데이터 기반의 4차 산업혁명 기술을 실제 조경공간의 조성․유지관리 및 서비스에 융합하여 실증하는 등의 후속적 연구가 필요하다.

Landscape Architecture is a minority manpower field that requires wide knowledge and experience. Therefore, the service market is narrower than other fields, and education service for practitioners is lacking. The purpose of this study is to propose e-learning content development methodology that can provide customized landscaping practical education according to the level of education and increase the economic efficiency of the development process. First, in theoretical review, the ADDIE model was modified to select the curriculum development model that pursues efficiency and introduced the concept of reusing learning objects in the SCORM-based model. In particular, to overcome the problems presented in the precious studies, the analysis and design stages have been strengthened and faculty designers with integrated knowledge of Landscape Architecture and ICT have led the overall phase. The actual development process is based on a step by step procedure--analysis of landscaping practitioners needs and environments, etc., teaching and learning procedures and the design of activities considering contents reuse, the first development such as actual shooting and editing, and the second development reusing the first development content--and was done in the order of evaluation and revision of professionalism and satisfaction. As a result of the study, the space-based courses composed of modular learning objects were first developed as 216 courses in 8 subjects, as 208 courses in 3 subjects in total, in which the modularized learning object are crossed and combined in units and difficulty-based courses were second developed in 216 courses with 3 subjects in total. As a result of the evaluation the satisfaction assessment of the overall satisfaction was 4.20 and the average value of the eight measures was 3.97, both being close to 4.0. For the professional assessment, the scores of 8 subjects were very high at 84.8 to 96.4 points. in context, the scores of 5 subjects were equal to from 89.9 to 96.4 points. In conclusion, as the study was conducted based on a clear understanding of the digital characteristics of e-learning contents and general characteristic of the landscaping industry, it was possible to develop a curriculum by developing a course composed of modular learning objects and reusing learning objects by unit. In particular, it has been proven to be effective in conveying professional knowledge and experiences via general procedures and provided an opportunity to overcome some analog problems that may occur in offline education. In the future, further studies need to be done by expanding the content and by focusing on segmented subjects. 조경은 폭넓은 지식과 경험이 요구되는 소수인력분야로 타 분야에 비해 서비스 시장이 협소하여, 실무자를 위한 교육 서비스가 부족한 실정이다. 이에 본 연구는 교육수요 수준별로 맞춤형 조경실무교육이 가능함과 동시에 개발 과정의 경제적 효율성을 높이는 이러닝 콘텐츠 개발 방법론을 제시하고자 수행하였다. 먼저, 이론 고찰에서 ADDIE 모형을 변형해 효율성을 추구한 교육 과정 개발 모형을 선정하였으며, 스콤 기반 모형의 학습객체 재사용 개념을 도입하였다. 특히, 선행연구에서 나타난 문제점을 보완하기 위해 분석, 설계 단계를 강화하였으며, 조경과 ICT에 대한 융복합 지식을 지닌 교수설계자가 전반적 단계를 주도하도록 하였다. 실제적 개발 과정은 단계별 절차에 의해 조경실무자 요구, 환경 등의 ‘분석’, 콘텐츠 재사용성을 고려한 교수학습 절차, 활동 등의 ‘설계’, 실제 촬영, 편집 등의 1차 개발, 1차 개발 콘텐츠를 재사용하는 2차 개발 등의 ‘개발’, 전문성, 만족도 등에 대한 ‘평가 및 수정’ 단계 순으로 진행하였다. 연구결과, 모듈형 학습객체로 구성된 공간별 과정이 총 8과목 216차시로 1차 개발되었으며, 모듈화된 학습객체를 단위별로 교차․조합한 분야별 과정이 총 3과목 208차시, 난이도별 과정이 총 3과목 216차시로 2차 개발되었다. 이에 대한 ‘평가’로 만족도 평가는 전반적 만족도 4.02, 8개 척도의 평균값은 3.97로 둘 다 4.0에 근접하였다. 전문성 평가는 8개 과목의 평가점수가 84.8~99.0으로 매우 높게 집계되었으며, 내용적으로는 5개 평가항목의 점수가 89.9~96.4점으로 비교적 균등하게 나타났다. 결론적으로 이러닝 콘텐츠의 디지털적 특성과 조경산업의 일반적 특성에 대한 명확한 이해를 바탕으로 연구를 수행함에 따라 모듈형 학습객체로 구성된 교육 과정 개발과 단위별 학습객체의 재사용에 의한 교육 과정 개발이 가능하였다. 특히, 보편적 절차에 의한 전문적 지식과 경험을 전달하는데 효과적임이 검증되었으며, 오프라인 교육에서 발생하는 아날로그적 문제점을 일부 극복할 수 있는 계기를 마련하였다. 향후, 콘텐츠 확충에 의한 추가연구와 세분화된 주제를 대상으로 연구할 필요가 있다.

In 1982, Environmental & Landscape Architecture(ELA), the first off-line printed media in Landscape Architecture, and in 2008, Lafent, on-line internet media, were published. The two media have developed along with the growth of the Landscape Architecture market. The total amount of information in Landscape Architecture area has been increased with knowledge and information-based generation, and its quantitative as well as qualitative needs have grown bigger. This study, therefore, compared and analyzed use orientations of the two media, focusing on the motivation of information use. For the study data, 768 samples collected by survey of subscribers of ELA and members of Lafent were used. As a result of data analysis, the two groups were clearly different in general attributes including gender, age, education, occupation, and the main task. For the main motive of use, ‘acquiring general landscaping knowledge’ for ELA, and ‘news and information in landscape architecture area’ were selected. Thus, the purposes of ‘learning’ for ELA and ‘keeping trend’ for Lafent were a lot. The periods of use of the two media were significantly different. ‘More than 5 years’ and ‘less than a year’ groups of ELA were more than those of Lafent. On the other hand, Lafent which has much shorter history had equal periods of use by category. Like the above results, demand markets are somewhat overlapped between the two journals, but independent areas by demander characteristics and motivational difference exist. Such results are assumed to be the consequences from the information content difference between prints and internet added by difference of general characteristics of demanders. Therefore, it is inferred that the two media needs to establish their direction in the future after considering such differences of demander composition and motivation.

In the field of environmental landscape architecture, the internet medium is used as an effective communication tool not only in the private level but also in the policy level. Recently, the active utilization of mobile web service is emphasized as the time changes, but there is not much improvement or advance in services due to lack of relevant studies. Therefore, this study is intended to provide basic data needed for improvement and advance by researching the quality of mobile web service among multichannel services provided in environmental landscape architecture related internet media. The model for measuring service quality is SERVQUAL, which was verified in the study of Choi(2015), Choi and Koo(2016), and the final valid samples are total 230. First, the subjects were analyzed as the representative media that are possible to acquire comprehensive knowledge related to environmental landscape architecture. Second, the highest importance level in each subsection was ‘protection and security maintenance of customer information’ followed by ‘Reliability about accurate information supply’. Regarding performance level, ‘Reliability about accurate information supply’ and ‘professional knowledge to communicate with users’ are highly evaluated. Third, regarding Importance-Performance Analysis(IPA), the first priority management should is ‘Tangibles’, and the next are ‘Responsibility’ and ‘Empathy’. The ones for maintenance of the status quo are ‘Reliability’ and ‘Assurance’, and there is none for effort reduction. Meanwhile, regarding the importance of each factor and difference in the quality of PC web service and mobile web service studied before, the biggest difference is in ‘Tangibles’, followed by ‘Assurance’, ‘Empathy’, ‘Responsibility’ and ‘Reliability’. It is suggested that the revitalization of Landscape information science(LB1106) presented in the National Science &Technology Standard Classification System is needed. In the future, it is necessary to research the change trend on users’ response through continuous evaluation of improved mobile web service.

This study was carried out to derive the functions of gardens. The rage of subject gardens include the enlarged gardens and similar land-use types such as urban parks, urban forests, plants garden, and open space, etc. As the results of this study, firstly 4 major types of gardens functions (draft) such as ‘culture functions’, ‘environmental functions’, ‘industrial functions’, ‘social functions’ were derived from literature studies. The cultural functions and environmental functions were further divided as 4 sub functions respectively, and the industrial functions and social functions were further divided as 2 sub functions respectively. And each sub function was divided with more detailed functions. Finally the functions of gardens (draft) were verified by FGI (Focused Group Interview) of the field related to gardening, and the final garden function was then grouped into three major categories such as cultural function, ecological function and social function. Each major category was divided into 4 sub categories respectively. Cultural functions were classified into ‘aesthetic beauty', ‘recreation healing', ‘spiritual religious inspiration', ‘cultural heritage and uniqueness'. Ecological functions were classified as ‘ecological environment protection', ‘climate change response', ‘water cycle', ‘disaster control'. The social functions are classified into ‘tourism recreation', ‘quality of life of local residents', ‘education', ‘industrialization'. Next, 12 sub-categories and 29 sub-indicators were set in detail by 2∼3 detailed sub-indicators for each major and sub-category. It is necessary to study the perceptions of experts and the general public on the proposed functions of gardens in this research. Also, further study is needed on the concept of a garden and similarities with public parks which are of similar land usage. 본 연구는 협의의 정원 및 정원과 유사한 성격을 지닌 토지이용형태인 공원, 도시숲, 수목원과 식물원, 오픈스페이스등을 포함한 광의의 정원을 연구범위로 설정하여 정원의 기능을 도출하고자 하였다. 본 연구결과, 먼저 문헌연구를 통해 정원기능 초안을 문화적 기능, 환경적 기능, 산업적 기능, 사회적 기능 등 4개의 대분류로 구분하였고, 문화적 기능과환경적 기능은 각각 4개의 중분류로, 산업적 기능과 사회적 기능은 각각 2개의 중분류로 구분하였다. 각 중분류별로선행연구에서 제시한 복수의 세부기능을 설정하였다. 다음으로 정원 관련분야 전문가 FGI를 통해 초안을 검증하여 최종정원 기능을 문화적 기능, 생태적 기능, 사회적 기능 등 3개의 대분류로 조정하였고, 각 대분류별 4개의 중분류로 각각구분하였다. 문화적 기능은 ‘심미적 아름다움’, ‘휴양치유’, ‘영적 종교적 영감’, ‘문화유산과 고유성’ 등으로 중분류하였다. 생태적 기능은 ‘생태환경 보호’, ‘기후변화 대응’, ‘물순환’, ‘방재조절’ 등으로 분류하였다. 사회적 기능은 ‘관광레크레이션’, ‘지역주민 삶의 질’, ‘교육’, ‘산업화’ 등으로 분류하였다. 다음으로 이렇게 재편된 각 대분류 및 중분류별로 세부기능을 2∼3개 내외의 세부지표를 각각 설정하여 총 12개의 중분류와 29개의 세부지표를 제안하였다. 본 연구에서 제안한정원의 기능에 대한 전문가 및 일반인들의 인식 연구가 필요하며, 아울러 정원의 개념, 유사 토지이용형태인 공원과의유사점과 차이점 등에 대한 연구가 필요하다.

정원 기능에 대한 인식 비교

The purpose of this study was to investigate the difference in perceptions between gardens and park functions as recognized by two groups, Group A and Group B, in order to confirm the distinction between concepts and functions and then establish the importance of individual functions. The AHP was used to analyze the importance of each group's perceptions by dividing them into garden and park, Group A and non-Group A, respectively. In Group A, the importance of garden functions were considered in descending order of importance to be cultural function, ecological function, and social function. In the general group, ecological function, cultural function, and social function also appeared, but in a different order of importance. As for the park functions, Group A recognized the importance of functions in a similar order of importance to the gardens: cultural function, ecological function, and social function. Group B thought that social function, ecological function, and cultural function have the same significance. At the major classification level, Group A and Group B emphasized the social function of the parks. Group A recognized the importance of the garden's cultural function as the most important, whereas the general group emphasized the importance of the garden's ecological function. As for the mid-class level, Group A recognized the aesthetic beauty, health, ecological environment protection, and water circulation as important functions of the garden. For Group B, the ecological environment protection, aesthetic beauty, water cycle, and health were important. The concepts and functions of gardens and parks are still largely mixed but are gradually becoming differentiated. As a follow-up study, it is important to systematically manage the functions of gardens by establishing design, construction, and monitoring DB techniques for the garden type and examine the hierarchy of various other gardens. 정원이 제도적 차원에서 공적영역으로 확대되며, 기능의 불명확성으로 인해 혼란이 발생하고 있다. 이에 본 연구에서는 정원 조성 및 이용자 관점, 즉 전문가와 일반인을 대상으로 정원 기능의 우선순위 인식을 규명하고, 정책적 방향성을 제시하고자 수행하였다. 연구방법론은 사회과학적 방법론인 AHP를 적용하였으며, 집단A 227명, 집단B 220명의 인식을 분석하고 비교고찰하였다. 먼저 정원의 대분류 기능에 대한 가중치 분석 결과, 집단A는 문화적 기능, 생태적 기능, 사회적 기능의 순으로 중요하게 인식하고 있다. 반면 집단B에서는 생태적 기능, 문화적 기능, 사회적 기능 순으로 나타나, 서로 간 인식 차이가 확인되었다. 둘째, 각 대분류별 중분류의 가중치 분석 결과에서는 문화적 기능에서 심미적 아름다움이 두 집단 모두 1순위로 나타났으며, 영적 종교적 영감, 문화유산과 고유성에서 순위 차이가 있었다. 생태적 기능에서는 생태환경 보호, 사회적 기능에서는 지역주민 삶의 질이 두 집단 모두 1순위로 평가되었으며, 나머지 중분류 우선순위도 모두 동일하였다. 셋째, 대분류 수준의 각 기능별 가중치를 곱셈한 중분류 기능의 종합적 분석 결과에서는 생태환경 보호, 심미적 아름다움, 휴양치유, 물순환에 대해 두 집단 모두 제일 중요하게 인식하였다. 반면 두 집단 모두 산업화를 가장 후순위로 인식하고 있었다. 종합하여 보면 공적 영역으로 확대된 정원은 이용자 중심의 공간 기능이 우선되어야 하며, 산업적 혼란을 방지함과 동시에 전문성이 존중되어야 한다. 즉, 생태환경 보호와 물순환 등의 생태적 기능을 최우선으로 하여, 심미적 아름다움, 휴양치유 등의 문화적 기능을 보완하는 것이 효과적일 것으로 판단된다. 후속 연구로서 정원의 유형과 위계, 기타 다양한 정원에 대한 설계와 시공 및 모니터링 DB를 구축하여, 정원의 흐름을 체계적으로 관리하는 것이 중요하다.
