  • The high-rise buildings have been indiscriminately located in the good natural landscape in Busan. They destroy the mountain skyline that is the key role of urban landscape and lower the index of greenness. Busan need the efficient management methods of the mountain skyline to improve the quality of urban life, the amenity of urban landscape, and the index of greenness. This study is to propose the method of building height restriction both through the GIS bases multiple sight surface analysis and through the analysis of the floor area ratio to make up for the weakness of single sight surface analysis has been used as a means of building height restriction. It studies the residential district with Hwangreung Mountain in the background at Deeyeon-don, Nam-gu, Busan. It achieves both objectivity and time efficiency by multiple sight surface analysis. Reflecting the result of this simulation at strategic viewpoints, it enables landscape planning to be comprehensive. Lastly it suggests building height regulation for protecting the mountain skyline which responds to the local conditions.

  • This study was performed to examine the optimum addition amount of Hizikia fusiformis powder to be used with rice flour in the preparation of Hizikia fusiformis Sulgidduk (traditional rice cake). Hizikia fusiformis powder was added to rice powder at ratios of 5, 10, 15 and 20% (w/w). The moisture content of Sulgidduk was increased with the addition of Hizikia fusiformis powder, whereas the pH content was decreased. The addition also lowered the lightness and yellowness values but increased the greenness value. Mineral contents were increased. Hardness, springiness, and brittleness were decreased, and cohesiveness was increased as the added powder content also increased. In the sensory evaluation of Hizikia fusiformis Sulgidduk, color, flavor, taste, softness, chewiness, moistness, cohesiveness, and overall acceptability characteristics were all highest at the 10% addition level. Thus it can be proposed that this is the ideal level of Hizikia fusiformis addition in terms of the sensory properties of the cooked product.

  • 아름다운 자연경관은 인구의 도시집중과 토목 건축 기술 기반의 도시공간구조 다양화로 자연경관은 그 모습을 잃어가고 있다. 이러한 변화 이변에는 자연경관의 보존에 대한 도시민의 욕구가 날로 증가하고 있어 경관자원의 보전 및 보호를 위한 체계가 필요한 실정이다. 체계적이고 종합적인 경관관리로 도시민들에게 우수한 경관을 제공하기 위해서는 경관의 변화 정도를 정량적이고 객관적으로 측정하고 모니터링 할 수 있어야 한다. 따라서 본 연구에서는 건물배치 및 높이에 따른 산림녹시율을 3D GIS기반에서 분석하여 산림녹시율이 인간에게 미치는 영향을 규명하고자 한다.

  • The RapidEye satellite sensor has various spectral wavelength bands, and it can capture large areas with high temporal resolution. Therefore, it affords advantages in generating various types of thematic maps, including land cover maps. In this study, we applied a supervised classification scheme to generate high-resolution land cover maps using RapidEye images. To improve the classification accuracy, object-based classification was performed by adding brightness, yellowness, and greenness bands by Tasseled Cap Transformation (TCT) and Normalized Difference Water Index (NDWI) bands. It was experimentally confirmed that the classification results obtained by adding TCT and NDWI bands as input data showed high classification accuracy compared with the land cover map generated using the original RapidEye images.

  • Mankind has just begun to recognize that the most crucial factor to achieve the sustainable society in the future is green technology. Most countries support the development of green technology to prevent catastrophes from global warming, mainly in the areas of reducing carbon dioxide from the atmosphere. However, most products we consume in everyday life are produced through chemical processes, and we often oversee the fact that the huge amount of waste and energy during these chemical processes will seriously influence our goal to achieve our future society sustainable. Thus the technologies to minimize the amount of disposed waste and energy consumption during chemical processes may be more important than to reduce the greenhouse gases. In this regard this review introduces the recent status of green chemistry and future prospects in order to help our chemists and engineers establish research projects based on the green chemistry principles.

  • This paper demonstrates that it is feasible to evaluate forest degradation and to detect deforestation in the 8156$km^2$ study area affected by expand farming using vegetation indices derived from Landsat TM data. The NDVI-growing stock relation was applied on th Landsat TM data and a 3 second grid DEM, whose coverages could improve the assessment of forest degradation and also estimate the rate of change of forest cover area depending on elevation intervals. The strength of the relationship between the ratio of the greenness and brightness indices and forest degradation conditions would have been more interesting in the deforested areas which were converted to crop farming land.

  • In the present study, we investigated the physicochemical characteristics and sensory qualities of gruel with added ground yam (20~80%) to increase consumption and application of yams. pH and sugar content of sample gruel decreased with increasing yam content, whereas spreadability increased gradually. Lightness and greenness decreased; however, blueness increased as yam content increased. Viscosity decreased with increasing yam content. Gruel with 40% added yam was the most preferred for flavor, taste, texture, and overall preference. From these results, we found that adding 40% yam was the best to make gruel with high sensory quality.

  • The Hwangtoh is one of the traditional construction material used in wall, plastering material, and ondol (Korean underfloor heating system) with stone and wood. It is an important greenness material and it has much advantages such as; high storage of heat, auto-purification, antibiotic ability, and emission of far infrared rays. But, it is not developed and not used in modern construction because of its low strength and properties of dry shrinkage crack. According to the recent researches and studies, it is evaluated for natural pozzolanic material like flyash or pozzolan. It's possibility on construction material is high because it's chemical and mineralogical proportion is like as Metakaolin and Kaolinite. In this point of view, this study aims to analyze the physical properties on Hwangtoh mortar through an experiment with various activation condition of Hwangtoh, which is natural pozzolanic material, for the purpose of increase the using possibility in construction material.

  • 식생의 생물계절학적 특성은 지표면과 대기의 에너지와 물 순환에 큰 영향을 미친다. 일반적으로 상층군락과 하층군락의 식생은 미기후의 차이 등에 의해 서로 다른 생물계절학적 특성을 가진다. 이러한 식생의 생물계절학적 특성은 반사도 관측을 통해 추정할 수 있다. 과거부터 원격탐사 기법을 활용하여 식생의 생물계절학적 특성을 추정하는 많은 연구가 수행되어 왔다. 그러나 대부분의 연구는 상층군락과 하층군락의 반사특성을 구분하지 않았다. 본 연구에서는 상층군락과 하층군락 식생의 생물계절학적 특성을 구분하여 탐지하기 위해 red, green, blue 그리고 near-infrared 의 네 가지 파장대를 가진 LED 센서를 이용하였다. LED 센서는 광릉 시험림 내의 활엽수림과 침엽수림 관측지에 서로 다른 네 군데의 높이에 설치되어 각 파장대의 반사도를 산출하였다. 또한 반사도를 이용하여 세 가지 식생지수(NDVI, EVI, Greenness index)를 산출하여 상층식생과 하층식생의 개엽기를 추정하였다.

  • Recently, an interest has developed in the use of whole green grains as functional food materials. The present study was conducted to provide the baseline data for the stable production of whole green grains in 20 cultivars of wheat by investigating the greenness of grain with maturation (from $20^{th}$ to $41^{st}$ day after heading, at an interval of 3 days). On the $20^{th}$ day after heading, the grains were dark green with a wrinkled long-oval shape. After the $35^{th}$ day of heading, the grains turned almost yellow with an oval shape. Their redness ('a' value of chromaticity) increased from the $20^{th}$ to $41^{st}$ days after heading, indicating a negative value up to the $32^{nd}$ day after heading. A significant decrease in their chlorophyll content was observed with maturation. The yield of whole green wheat grain (including greenish yellow grain) was the highest from the $32^{nd}$ to $35^{th}$ after heading. Therefore, we concluded that the optimal harvesting period for whole green wheat grain was from the $32^{nd}$ to $35^{th}$ day after heading. The heading time of various cultivars ranged from April 28 to May 5, the time of Jopummil cultivar grew the fastest among them, such as Gurumil, Alchanmil, but Dahongmil got the latest in heading time. The greenness of seven cultivars (Jeokjungmil, Keumkangmil, Jogyeongmil, Jopummil, Baekjungmil, Yeonbaekmil, and Milseongmil) was relatively higher than that of the others. The yield of greenish whole grain was relatively high in six cultivars (Alchanmil, Baekjungmil, Eunpamil, Yeonbaekmil, Dahongmil, and Urimil). Based on their greenness and yield, the Baekjungmil and Yeonbaekmil cultivars have been considered to be optimal for the production of whole green wheat grain.
