  • Nowadays, there are increasing demands of golf courses and it is necessary to make more golf courses than the present. To do this, we need to improve the environmental problems with the regional inhabitants, and it is said that the first thing to be considered in developing any golf course in Korea is to preserve the environment. In this context, the purpose of this study is to set forth several design factors to lessen the negative impacts which are accompanied with the development of golf courses. 1. The present conditions of golf courses in Korea Many new golf courses have come into being, particularly since the late 1980s, and now, in the year of 1997, over one hundred of golf courses are doing their business, yet the number of golf course is still less than required. So far, over a half of them have been made in the vicinity of Seoul on account of various reasons, and this has adversely affected on our natural environment. This unreasonable development of golf courses has caused serious water pollution, landslides and the other problems. Also, the topography of Korea is not good for golf courses. Although the demands of golf courses are increasing, the suitable sites for them are very limited, and therefore it is sometimes unavoidable to make golf courses on steep hills. Consequently, in designing golf courses in Korea, the most important thing is the balance between natural environment and artificial environment. 2.Eco-friendly golf course design factors 1) The concept of eco-friendly golf courses Ecologically sustainable and sound golf courses which are made by eco-friendly approaches 2)Basic conditions of eco-friendly golf courses (1)The most suitable sites (2) Conservation of existing ground as much as possible (3)Proper use of agricultural chemicals which have great impacts on the environment (4) Reasonable use of fertilizers (5) Developing a specialized fertilizer only for grass (6) Adaptation of organic agriculture (7) Improvement of grass sorts (8) Establishing reservoirs for purifying the water from golf courses 3) Eco-friendly golf courses (1) Location-Enough area /Gentle slope/Winding ground/Including lakes or streams /Not crossing wind's main direction Facing south or southeast /Suitable soIl for grass /Good drainage /Low level of underground water (2)Course layout and design -Consideration about existing contours as much as possible -Adaptation of Scotish design trend -Various holes' configuration -Consideration toward surrounding landscapes -Reducing grass areas -Giving buffer zones -Adapting computer methods in the process of site analysis and design (3) Eco-friendly considerations in constructing and managing golf courses -Protection of wildlife -Reuse of existing forests and preservation of topsoil -Renovation of old-fashioned courses -Reducing grass areas -Purification of water -Standization of management -Strict regulations against chemicals -Recycling organic materials -Through separation of the water inside golf courses and out of bounds -Getting proper construction works done in a due time 4.Eco-friendly considerations from a viewpoint of cultural environment 1) Well-matched landscape design and events planning 2) Implement of identifications and awarding systerns 3)Acknowledgement of superintendents' qualitications in the maintenance of golf courses 4)Increasing public golf courses and keeping good relationships with the neighbors near golf courses Key words: Pro-environmental development, Golf course.

  • 지속가능성이란 사회적, 경제적, 환경적인 영향을 전반적으로 고려하며, 인간의 건강과 생활 증진을 내포하고, 환경자원의 보호와 경제적 번영을 의미한다. 지속가능성에 대한 심도 있는 이해는 이러한 환경적인 영향에 대한 고려뿐만 아니라 원료 및 자원채취, 이송, 생산 협력의 전반적인 순환을 다루어야 한다. 화학산업의 지속가능한 발전은 화학공정안전의 발전을 통한 상호보완적인 강화없이 이루어지기 어렵다. 이러한 관점에서 화학공정안전은 국제시장에서 경쟁력 강화의 기회라고도 할 수 있다. 화학공정안전의 변화하는 새로운 패러다임은 현존하는 시스템과 생산공정의 기본 디자인을 고려한 총체적 순환 전 과정으로부터 나온다. 이렇게 화학공정안전을 향상시키기 위해서는 관리 시스템을 포함한 정량적 위험성 평가 방법과 다양한 공정안전 데이터 및 지식베이스를 포함한 통합 스마트시스템의 개발이 필요하다. 본 논문에서는 화학산업안전의 전 과정 순환의 필요성에 대해 언급하였고, 이를 향상시키기 위한 공정안전 신기술에 대해 논의하였다. 변화하는 공정시스템공학에서 사고 없는 지속 가능한 산업의 발전을 위해서는 3 가지의 S, 즉 안전(Safety), 안정(Stability), 안보(Security)의 조합이 적절히 이루어져야 할 것이다.

  • 콘크리트의 배합설계와 압축강도 평가는 지속가능한 구조물의 내구성을 위한 기초적인 자료로서 활용되고 있다. 하지만, 콘크리트 배합설계는 최근 배합요소의 다변화 등의 이유로 인하여 정확한 배합요소 산정이나 기준값 설정에 어려움을 겪고 있다. 본 연구에서는 인공지능 기법 중 하나인 딥러닝 기법을 사용하여 삼성분계 콘크리트의 배합요소를 산정하는 양방향 해석의 예측모델을 설계하는 것을 목적으로 한다. 콘크리트 배합요소 산정을 위한 DNN 기반 예측모 델은 층 수, 은닉 뉴런 수를 변수로 한 총 8개의 모델을 사용하여 성능평가 및 비교를 실시하였으며, 이후 학습된 DNN 모델을 사용하여 소요압축강도에 따른 콘크리트 배합 산정 결과를 출력하였다. 모델의 성능평가 결과, 콘크리트 압축 강도 인자에 대하여 평균 약 1.423%의 오류율을 나타내었으며, 삼성분계 콘크리트 배합인자 예측에 대하여 평균 8.22%의 MAPE 오차를 만족하였다. DNN 모델의 구조별 성능평가 비교 결과, 모든 배합인자에 대하여 DNN5L-2048 모델이 가장 높은 성능을 보였다. 학습된 DNN 모델을 사용하여 30, 50MPa의 소요압축강도를 가지는 삼성분계 콘크 리트 배합표 예측을 진행하였으며, 추후 학습을 위한 데이터 세트 확장과 실제 콘크리트 배합표와 DNN 모델 출력 콘 크리트 배합표 간의 비교를 통한 검증 과정이 필요할 것으로 판단된다.

  • Purpose: This study was conducted to figure out the cognitive characteristics of the elderly living in apartment complex in order to construct basic data for the design of sustainable and age friendly apartment area. Methods: Cognitive map was used to identify and analyze the elderly residents' status of residential environment cognitions. The elderly living in Gongreung-dong apartment was randomly interviewed outdoor area and requested to draw cognitive maps on their living environment. 26 valid cognitive maps collected were analyzed, classified into two different types: Line type and Dot type. The average age, cognitive distance, length of residence, number of elements in the map(complexity) were then compared by Line and Dot type, as well as by gender. Correlations among variables also were analysed. Results: Males showed a tendency to draw dot types, which means they are place-centered, and females drew line types more than males, which means they are way-centered. The average cognitive distance of male group was greater than that of female group. As the age went up, the number of perceived place and the cognitive distance decreased. Oder people tended to draw line types rather than dot types. As the cognitive distance was longer, the perceived place and the number of lines increased. Implications: The age was more related to the recognition of the residential environment. The younger the residents were, the more they recognized the elements. The points that were represented by dots in the cognitive maps are places for memories for the individuals. Creating more memorable spaces will affect the cognition of residents on living environment. It is better to improve the cognitive environments before cognitive abilities of residents decrease.

  • China, as a developing country with a great number of population and relatively less energy resources, reasonably emphasizes the nuclear energy utilization development. For the long term sustainable energy supply, as for nuclear application the basic strategy of PWR-FBR-Fusion has been settled and envisaged. Due to the economy and experience reasons the nuclear power and technology development with a moderate style are kept in China up to now. In China mainland apart from two NPPs with the total capacity of 2.1 GWe in operation, four NPPs are under construction and two NPPs are planned for the Tenth Five Year Plan(2001-2005). Also another one or two NPPs are still in discussion. It could be foreseen that the total nuclear power capacity will reach 8.5GWe before the year 2005 and 14-15 GWe before 2010 respectively. As the first step for the Chinese fast reactor engineering development the 65MWt China Experimental Fast Reactor(CEFR) is under construction. The main components of primary, secondary and tertiary circuits and of fuel handling system have been ordered. The reactor building under construction has reached the top namely 57m above the ground. More than one hundred components and shielding doors have been installed. It is planned that the construction of reactor building with about 40,000$m^2$ floor surface will be completed in the end of the year 2002 and envisaged that the first criticality of the CEFR will be in the end of 2005. The second step of the Chinese fast reactor engineering development is a 300MWe Prototype Fast Breeder Reactor which is only under consideration up to now. Some important technical selections have been settled, but its design has not yet started.

  • In Korea, a movement for forming intentional communities is gathering people's interests to improve individualistic living environment, and to create a humanistic lifestyle. However, it is difficult to say if its management is successful or not, because intentional community is just in the experimental stage in Korea. The purpose of this study is to identify actual condition of residents' participation in forming process, shared activities in their daily lives, residents' regulation, common facilities and its management in order to offer basic information for revitalization of intentional communities in Korea. 7 intentional communities including eco-friendly villages, religious communities and a cooperative housing community were collected as the study objects. Upon analysis, those communities were divided into two groups according to their purpose of establishment; "HC (Housing-life focused Community includes cooperative housing community and eco-friendly community)" and "IC (Ideology focused Community includes ideology community and religious community)" in order to identify difference in residents' participation between the two groups. In-dept interviews with representatives of 7 intentional communities by a structured questionnaire were used as study method. The findings of this study are as follows; In general, more active residents' participation is identified in ICs than in HCs. There is no common house, which is considered as essential in intentional community, in HCs, while it was facilitated in all ICs. Role of leader seems more important in ICs than in HCs. About the ownership of housing and land, private owned is common in HCs, while community owned is common in ICs. Shared activities and residents' regulations are evidently less in most HCs than in ICs. Furthermore, in order to run a community sustainable, it is crucial to encourage sense of community among residents, and developing common house and activity programs. Common house design, which can promote proactive residents' participation in shared activity should be studied fitted to Korean circumstances. Above all, proactive participation in the shared activities is one of the most important factors in intentional community.

  • Purpose: Korean society is undergoing the rapid increase and poverty of elderly population. Therefore, the appropriate supply and planning of public rental housing for the low-income elderly is more important. The purpose of this study is to present the basic data for the study and planning of the elderly housing complex by analyzing the cognitive characteristics of the elderly residing in the rental housing. Methods: A questionnaire survey was conducted to identify health characteristics of the elderly living in the 'Gongreung SH Apartment'. 100 random samples were collected and 82 valid samples were analysed. Statistical analysis was performed using Excel and R for the age, sex, health, outdoor walking frequency and characteristics of Cognitive map of the elderly. Results: The characteristics of cognitive map were classified into point shapes and linear shapes. The linear group was lower in average age than the point group and tended to draw the map wider. The wider the map was, the more the number of elements in cognitive map was. The number of elements on the cognitive map decreased as respondents' age increased. On the other hand it was not related to residence period and gender of the elderly. Implication: The cognitive extent of the residential environment tends to decrease with age. Men's cognitive range is wider than women's. There is no corelation between the number of cognitive elements and cognitive map type. Men tend to have a systematic image of city, whereas women focus on relational and social urban factors. For sustainable apartment complex design, various characteristics of the group including men and women, different age and different health status should be considered.

  • As a series of basic research to draw the pilot design measures for developing the habitat apparatus of Sulculus diversicolor supertexta inhabiting the coastal area of Jeju island, this study conducted a water tank experiment to understand the habitat marine environment of Sulculus diversicolor supertexta and the preference of habitat space focusing on the research fisheries performing the discharge of marine products. In the composition degree of marine algae in both fisheries, Donggwi-ri showed the highest gulfweed (79.3%) as brown algae and there were some coralline algae (17.2%) as red algae. Hansu-ri yielded the highest gulfweed (48.1%) as brown algae, which was followed by sea lettuce (10.4%) as green algae. In the preference of habitat space, the shelter angles 40° showed the highest adhesion as number of 82.9, which was followed by 60° and 70° as 69.2 and 68.2 respectively (P<0.05) by reviewing the environmental characteristics of habit of Salculus diversicolor supertexta in the coastal fishery of Jeju Island, when considering the adhesion rate in each of five shelters with different angles. In the future, there should be continuous research and monitoring for designing the fish shelters suitable for the coastal fisheries of Jeju island, and it would be also necessary to add the field-centered sustainable concrete research.
