본 연구는 가로수 식재환경 및 생육 상태를 조사하여 가로환경 생육공간의 합리적인 개선을 위한 기초 자료를 제공하기 위하여 그 목적으로 서울시 관악구 가로수의 지상부 및 지하부 생육환경 등을 조사하여 개선방안의 주요 결과를 요약하면다음과 같다. 토양 비옥도는 상업 및 업무가로와 일반생활 및 생태네트워크가로의 측정 결과 치환성 양이온 중 Mg의유의확률이 0.05보다 작은 0.01이므로 통계적으로 유의한 차이가 있고 그 외 나머지 pH, 유기질, K, Ca, Mg, Na,양분 보존능, 염기 포화도는 구시가지와 도심에 따른 유의확률이 0.05보다 커 차이가 없어 일반적으로 가로유형에따라 비옥도 차이는 없는 것으로 사료된다. 토양경도는 상업 및 업무가로의 평균토양 경도지수는 보호판이 설치된지역이 21.5, 미설치된 지역은 35.5이었으며 일반생활 및 생태네트워크가로는 보호판의 설치지역이 24.5, 미설치지역은29.2로 나타났다. 또한 경도지수는 상업 및 업무가로와 일반생활 및 생태네트워크가로에 따른 유의확률이 0.05보다큰 0.741이므로 통계적으로 유의한 차이가 없음을 알 수 있어 가로유형에 따른 차별성이 보이지 않고 있다. The results of measuring the fertility of the earth on commercial and business streets and residential streets showed that the significant probability of Mg among substitutive positive ions, there was a statistically significant difference. There was no difference in the level of fertility depending on street patterns because the pH, an organic element, K, Ca, Mg, Na, nutrition preservation density, and level of saturation of the chemical base was larger than 0.05 in terms of significant probability based on the old city sector and urban center. In terms of the hardness of earth hardness index, the average earth of the commercial and business street was 21.5 mm for areas was installed. For areas without a protective plate, the index was 35.5 mm. The earth hardness index of the average earth of residential streets and parks was 24.5 mm for the area where a protective plate was installed and was 29.2 mm for the area without a plate. In addition, in connection with the hardness index the significant probability for commercial and business streets and residential streets and parks was 0.741, which is larger than 0.05. Thus, there was no statistically significant difference in the street patterns.

This Study newly defined ‘The 4W Hologram’; realistic stage projection technology, and established the basic principles and features. The 4W Hologram is similar to the projection technology previously used in the collaborated production of <KARMA: Rhapsody of Destiny>, <Kicks>, <Larva> and <Bamboo Show>. 3D Hologram technology is dependent on overseas production and high-cost, low-efficiency components, such as foil screens. However, The 4W Hologram has shown to be a low-cost, highly-efficient solution of great commercial value. Therefore, The 4W Hologram represents the next generation of realistic stage projection technology. We aim to create the framework for commercializing The 4W Hologram and wish to set a new standard for projection technology in the future. 본 연구는 국내 융합공연콘텐츠 <카르마 : 운명의 랩소디>, 모던 태권도 <킥스>, 홀로그램 뮤지컬 <라바>와 <뱀부쇼> 등에 유사 홀로그램 형태로 적용되어 안정적으로 상용화를 이룬 입체무대영상기술을 ‘4W 홀로그램’으로 새롭게 정의하고 그 구현원리와 특징을 정리하였다. 기존의 경사형 포일스크린(Foil screen) 기반의 플로팅 방식 입체무대영상기술은 해외기술에 의존한 고비용·저효율의 기술인 것에 반해 본 연구에서 새롭게 정의하는 4W 홀로그램은 국내기술로 상용가치를 높인 저비용·고효율의 차세대 기술이다. 이에 본 연구는 차세대 입체무대영상기술로 부상한 4W 홀로그램 기술을 새롭게 정의하고 표준화함으로써 기술상용화를 위한 이론의 틀을 구축하고 차후 응용기술 개발을 위한 초석을 마련하고자 한다.

This study was conducted to grasp the effect of afforestation of cut slope using coir blocks on the improvement of scenery and the management of non point pollution source. Total four experimental tanks such as general soil slope, coir blocks, installation slope, slope refilling the inside of coir blocks slope with pebble, slope refilling the inside of coir blocks with soil and plant were installed, pollution source water was supplied and the possibility of reduction management of non point pollution source was analyzed at four items of COD, SS, T-N, T-P and main results drawn from this study are as follows. In conclusion, biodegradable materials like coir blocks and soil and plant layers are judged to be helpful in reduction management of non point pollution source inflowing to water space from land area. Thus, the reduction of non point pollution source occurring at land area is thought to be fully controlled at the cut slope, the space prior to inflowing to water ecological space like a stream or a swamp area.

High-performance liquid chromatography (HPLC) and capillary electrophoresis (CE) were used to identify five active components in the modified herbal decoction Bo-Yang-Hwan-O-Tang (mBHT), i.e., amygdalin,decursin, paeoniflorin, salvianolic acid B, and calycosin-7-O-β-D-glycoside. These components were identified by comparing their retention times and mass spectra with those of reference compounds. The conditions of both analytical methods were optimized and validated. Sufficient separation of target analytes was achieved using a buffer consisting of 40 mM sodium borate and 60 mM sodium dodecylsulfate (SDS) containing 10% methanol (pH 9.5) at 250 nm for CE analysis and gradient elution with a water-methanol mobile phase and ultraviolet (UV) photodiode array detector (DAD) at 250 nm for HPLC analysis. The mBHT components were determined within 65 min by HPLC and 16 min by CE. All calibration curves showed high linearity (R > 0.999) within the ranges tested. Intra-day and inter-day precision were less than 1.6% and 1.8% for HPLC and 2.5% and 4.8% for CE, respectively. The accuracy of the methods ranged from 98.8% to 102.3% for HPLC and from 95.9% to 108.2% for CE.
