Since Seoul city supplied 'Sangsang Children's Park', domestic children's parks are changing from formal facilities to creative play space recently. From eco-friendly safe playground model development project, the awareness of eco-friendly playground, namely children's park is increasing and its necessity is magnified. However, we could not know how well most children's parks aimed at the eco-friendly playground reflect eco-friendly features and whether they are eco-friendly or not because there are not the specific planning guidelines and evaluation standards for making the eco-friendly playground or children's park. Therefore, in this study we established the environment-friendliness evaluation standards of children's parks and estimated the environment-friendly features of the 9 parks built on the subject of green among Sangsang Children's Parks. In the observational survey of the 9 parks, we evaluated the environment-friendliness of these parks in the 8 fields(location and placement, ecological environment, play space, play equipment and facilities, additional facilities, materials and resources, energy saving, environmental load reduction) according to the levels(suitable, partial reflection, unsuitable, non-reflection) of reflection of eco-friendly planning factors. The assessment results showed that 4 items (location and placement, additional facilities, play space, play equipment and facilities) were suitable and others (energy saving, environmental load reduction, ecological environment, materials and resources) were partial reflection or unsuitable. Therefore, on the basis of these results, this study proposed the planning indicators to be considered first and the planning factors that should be complemented and improved in the construction of eco-friendly children's park in future.

In the 21^st century, the demand for eco-friendly leather, such as eco-leather and vegan leather, is steadily increasing. This study examines the influence of eco-friendliness on consumers' purchasing intentions and the possibility of eco-friendly changes in the fashion accessory market, which is dominated by leather material and leather substitutes. This study administered a questionnaire survey to 227 males and females between 20 and 60 years of age in Korea. With a 5-point Likert scale, data were collected on evaluation criteria when purchasing shoes and bags and purchasing intention of various leather substitute materials according to the democratic variables. The eco-friendliness attitude was divided into eco-consciousness and green behavior. As the eco-friendly attitude increased, most purchasing standards increased, but the purchasing criteria, such as trends, brands, and prices, did not correlate with the eco-friendly attitude. The eco-consciousness of a consumer had a high correlation with the design evaluation criteria, while the green behavior of the consumer aligned with durability and comfort criteria when purchasing a bag. There was a preference for recycled leather, vegetable leather, synthetic leather, and chemical leather, and the fabric type was ranked as natural fiber, biodegradable fiber, and synthetic fiber. Consumers with both green behavior and eco-consciousness are more likely to purchase biodegradable textiles and vegetable leather for the material of shoes and bags.

Eco-friendly material and implementation methods have become important along with the existing standardized maintenance concept for the irrigation and flood control. However, the intrinsic function of the hydraulic structure is water supply and disaster prevention. Therefore, the material and work methods should be considered both eco-friendliness, durability and safety which are prerequisite elements to maintain the engineering function. In this study eco-friendly material and work methods would be classified into the vegetation based system, eco-friendly concrete system and stone-material system according to the characteristics of material. The quality standard for durability followed KS specification and related regulations. The quality standard for safety and eco-friendliness was set after literature review, and the database was developed using the standard. The structure applicable to onsite - the eco-friendly material and work method were classified based on the function and material of the hydraulic structure. Finally, database has been established for convenient management and selection of the proper material and work method. The eco-friendly material and work method could be searched easily for the convenience of the users, and the web-based data system has been developed for continuous registration of the material and work methods to be developed in the future.

This study aimed to determine eco-friendly factors on the aspects of library service, materials provided or handled by the library, and programs including educational programs. Furthermore, it was setup to perform a trial evaluation for the eco-friendliness of the library based on the determined evaluation standards by this study. Results are as follows; First, regarding the question of 'Do employees of the library think that establishment of green libraries is necessary?', the employees of the libraries responded yes by 65.52%, but only 4.6% responded that it would not be necessary. Second, in analyzing the most important evaluation areas of green libraries according to the opinions of the libraries' employees, they were ranked in order: the indoor environment, energy and prevention of environmental pollution, and material and resource areas. Third, 11 areas were determined to evaluate the level of greening in the libraries; the highest averages were scored 510 for the area of energy and prevention of environmental pollution, 415 for the area of library resource, and 320 for the area of indoor environment. Last, the libraries were graded based on actual data according to the results to measure the level of greening, two libraries were graded as Diamond, the highest grade, accounting for 15.39% of all libraries; Gold and Silver grades accounted for another 15.39%, together five Certified graded libraries accounted for 38.46%, which was the highest rate among the libraries. Any library scoring less than 20% when compared to the full score was graded as Non-certified, and one library, which scored 15.06% fell into this category. The results of this study set up to serve as basic data for the direction of development for green libraries in our country, as well as reference for the employees of libraries in constructing or remodeling library buildings, establishing service infrastructure, providing information service, and planning library duties in an eco-friendly way.

In order to estimate how diverse the mating types in Pleurotus eryngii from different regions are, pairings between monokaryons derived from inter- and intra-groups were done. Sixteen and 15 alleles were identified at loci A and B from the 12 strains. In the P. eryngii KNR2312, widely used for commercial production, four mating loci, A3, A4, B3, and B4, were determined. Those loci, except A3, were found in 4 strains out of 12 strains. To improve breeding efficiency, especially in mating type determination, RAPD and BSA were performed to screen for a mating type specific marker. The SCAR marker 13-$2_{2100}$ was developed based on the RAPD-derived sequence typing B3 locus. The sequence analysis of 13-$2_{2100}$ revealed that it contained a conserved domain, the STE3 super-family, and consensus sequences like the TATA box and GC box. It seems likely that the SCAR marker region is a part of the pheromone receptor gene.

최근에 상하수관로, 지역난방 열공급관로 등의 유지보수가 증가하면서, 도로절단기에 의한 도로절단 작업도 급증하고 있다. 이러한 도로절단 작업은 소음과 함께 분진(절단슬러지)을 많이 발생시키므로, 저소음, 분진회수 등 친환경적인 기술이 적용될 필요가 있다. 기존에 이러한 문제점을 해결하고자 분진을 회수하는 장비가 개발된 사례가 있으나, 친환경성이 정량화되지 않았다는 한계가 있었다. 이에 본 연구에서는 소음 및 분진과 같은 환경위해요인의 발생원인을 근본적으로 제거할 수 있는 저소음·분진회수형 도로절단기를 개발하고, 이 절단기로 수행하는 도로절단작업 과정에 대한 친환경성을 평가하였다. 이를 위하여 본 연구에서는 진공장치와 슬러지흡입부로 구성된 수냉-슬러지회수 통합시스템을 개발하고, 개발된 시스템을 도로절단기에 적용하였다. 그리고 개발된 장비를 테스트 베드에 적용하고, 친환경성 관련 데이터를 수집하여, 친환경성을 평가하였다. 평가 결과, 개발된 장비의 절단슬러지 회수율은 83% 이상이었으며, 소음도는 82~83 dB, 음향파워레벨은 115 dB 수준이었다. 본 연구의 결과는 향후 도로절단기를 개선하는 과정에서 절단슬러지 회수성능과 저소음 성능을 향상시키는 데에 기초자료로 활용될 예정이다.

관광단지 개발사업은 자연환경이 양호하고 경관이 우수한 지역을 대상으로 추진됨에 따라 주변 지역에 대한 환경부하를 지나치게 가중하는 점이 문제로 제시된 바 있다. 이에 본 연구에서는 2012년~2021년간 이루어진 국내 관광단지 개발사업의 환경영향평가 결과를 토대로 동 사업으로 야기되는 환경영향을 파악하였다. 특히 다양한 환경영향을 종합적·정량적으로 분석하고자 선행연구를 통해 마련된 EA-INDEX를 관광단지의 사업 특성에 적합하게 신규 도출하였으며, 이를 통해 관광단지 개발사업의 환경영향을 크게 자연환경 보전, 자원 보존, 생활환경 보호 부문으로 구분하여 각 세부 지표별로 살펴보았다. 그 결과 지난 10년간 국내 관광단지 개발사업은 친환경성이 증가하는 방향으로 추진·개발된 것으로 나타났으며, 특히 자연환경 보전 부문에서 그 증가 추세가 뚜렷함이 확인되었다. 반면 자원 보존 부문의 경우 친환경성이 감소하는 것으로 확인되었으므로 추후 신규 개발계획 수립 시 이를 제고할 수 있는 노력하는 것이 필요할 것으로 판단된다. 본 연구는 비교적 장기간에 걸친 관광단지 개발사업에 대한 환경적 영향을 파악하고, 특히 개발사업의 친환경성에 대해 각 세부 부문별 영향을 정량적으로 분석한 것에 의의가 있는 것으로 판단된다. 추후 개발사업과 관련한 정책 이벤트, 연관 사회적 이슈 등의 정보를 종합한 분석이 이뤄진다면, EA-INDEX를 활용한 개발사업의 경향 파악에 더욱 폭넓은 해설이 가능할 것으로 기대된다.
