본 연구의 목적은 대규모 주택단지 개발지로 계획되어 있는 대구광역시 북구 연경동 및 동구 지묘동 일원을 대상지로 선정하여 조망점 선정을 통해 조망대상 및 대상장을 정량적으로 평가해 보고, 이를 토대로 시뮬레이션을 실시하여 계획적 차원에서 개선방안을 제시해 보는데 가장 큰 의의를 두었다. 연구결과를 요약하면 다음과 같다. 우선 조망대상 선정을 위한 문헌분석 결과, 도출된 조망대상은 총 24개로 나타났으며, 최종적으로 도출된 주요 조망대상은 4가지로 나타났다. 다음으로 도출된 조망점 선정기준은 총 15개로 나타났으며, 이들은 다시 공통적인 특성에 따라 조망성, 접근성, 공공성으로 재분류하였다. 예비조망점은 공공성 및 접근성을 평가하여 선정하였으며, 평가 결과, 총 42곳의 예비조망점이 선정되었다. 최종조망점은 선정된 예비조망점을 대상으로 조망성을 평가하여 선정하였으며, 평가 결과 29개의 최종조망점이 선정되었다. 마지막으로 문헌분석 결과, 도출된 평가지표는 총 26개로 나타났다. 조망점별 가치평가 결과, 29곳의 대상장 중 I등급은 2곳, II등급은 3곳, 가장 낮은 V등급에 해당하는 대상장은 3곳으로 나타났다. 다음으로 개선방안을 위한 문제점 분석 결과, 개발계획도면을 고려하지 않은 대상장-1의 경우, 토지모자이크의 다양성 등 4가지 개선지표가 선정되었다. 또한 개발계획도면을 고려한 대상장-2의 경우, 배후 산림으로의 조망이 잘 이루어지며, 시각회랑의 확보가 가능한 건축물 배치 형태는 직각배치, 층수는 약 10층인 것으로 나타났다. The purpose of this study is to quantitatively measure the view target and the view area through the selection of landscape control point by selecting Jimyeong-dong Dong-gu and Yeongyeong-dong Buk-gu Daegu, which are planned as the large scale housing complex development area, as the target places. It is very meaningful that from the simulation based on this measurement, the improvement methods are attempted to be suggested at the project level. The results of this study are as follows. First, the total number of viewing targets derived from the literature analysis for the selection of the viewing targets was 24, and finally derived main viewing targets were 4 places. Second, the total number of selection criteria of the derived landscape control point was 15, and these were re-categorized as prospect, accessibility and publicness according to the common property. The preliminary LCPs were selected by measuring the publicness and accessibility, and because of the said measurement, a total of 43 preliminary LCPs were selected. The final LCPs were selected by estimating the prospect of the selected preliminary LCPs, and as a result of estimation, a total of 29 final LCPs were selected. Finally, the total number of evaluation indicators derived from literature analysis was 26. Because of the valuation by the landscape control point, it was found that the 2 view areas were the I grade, 3 areas were II grade and 3 areas were the V grade, the lowest grade among 29 view areas. From the analysis on problems for the improvement methods, 4 improvement-indicators including the diversity of land mosaic were selected for the view area-1 without considering the development project drawing. In addition, for the view area-2 with considering the development project drawing, the landscape as the scenery forests was well formed, and the arrangement of architectures for the security of view corridor was right angle arrangement, and their floor number was 10.

본 연구의 목적은 비오톱 유형화 방법분석, 우점 비오톱 유형분석, 도시별 인문 자연 환경적 특성분석 및 군집분석을 통해, 국내 도시 비오톱 유형 특성을 분석하고, 전국적으로 적용 가능한 국내 도시 비오톱 유형 체계를 설정해 보는데 가장 큰 의의를 두었다. 연구결과를 요약하면 다음과 같다. 먼저 비오톱 유형화 방법 분석 결과, 분류기준 및 분류위계에서 도시마다 차이를 보이고 있었다. 다음으로 우점 비오톱 유형 분석 결과, 대부분의 도시에서 가장 많은 면적을 차지하고 있는 유형은 산림인 것으로 나타났다. 도시별 특성분석 결과, 도시들마다 상이한 결과를 보이고 있었으며, 군집분석 결과, 도시들은 총 5개의 군집으로 분류되었다. 먼저 Cluster-A의 경우, 낮은 인구수 및 도시화 현황을 보이고 있었다. 또한 타 도시와는 달리 농경지의 면적비율이 가장 높게 나타났다. 더불어 Cluster-C의 경우, 매우 높은 도시화 현황 및 인구수를 가지고 있었으며, 이러한 특성을 바탕으로, '산림 비오톱 중심의 광역형 도시(Large-sized metropoilitan cities-center of forest biotope area)' 군집으로 명명하였다. 이상과 같은 본 연구의 결과는 기존 비오톱 지도의 수정 및 보완 그리고 새로운 비오톱 지도 작성 시 표준화된 비오톱 유형 체계를 바탕으로 혼란을 최소화함은 물론, 도시 특성에 맞는 유형의 세분화 및 보전이 가능하도록 하는데, 중요한 역할을 수행할 수 있을 것으로 판단된다. The purpose of this study is to analyze the biotope characteristics of Korean cities and set up biotope type structures for Korean cities based on biotope type classification, dominant biotope type, city's human and nature environmental characteristics and cluster analysis. The findings of the study are summarized as follows: First, regarding the analysis of biotope type classification, cities showed differences in terms of the standard of biotope classification and classification hierarchy. Next, the analysis of dominant biotope types showed the type of forest represents the largest area in most cities. Moreover, a city's characteristic analysis revealed large differences between cities. As a result of cluster analysis, cities were classified into five clusters overall. First, Cluster A showed a lower population level and urbanization level. Unlike other cities, Cluster A revealed that it has the largest percentage of agricultural areas. Cluster C showed very high levels in terms of population amount and urbanization conditions was named the 'Large-sized metropolitan cities-center of forest biotope area' based on it's characteristics. The findings of this study as summarized above are considered to play an important role in enabling detailed classification and preservation of biotope types fit for the characteristics of cities and minimizing the confusion caused by different biotope mapping methods when revising and complementing biotope maps.

The main thrust of this paper is to investigate current status and problems of heat recovery ventilator operation in high-rise apartment buildings. However, the survey performed in this research reveals that a number of heat recovery ventilators are not operated correctly by residents. First of all, it is found that occupants usually avoid powering their ventilators and just open windows in order to save their utility cost. However, inherent characteristics of high-rise buildings, such as highly air-tight envelopes and lack of operable windows make it difficult to meet the ventilation needs without mechanical ventilation. In addition, depending on occupants' decision in tuning on or off of ventilation units may be the biggest problem in current ventilation system operation. Consequently, the followings are suggested in this research for improving mechanical ventilation performance in high-rise apartment houses.

The main thrust of this paper is to investigate current status and problems of heat recovery ventilator operation in high-rise apartment buildings. Since 2006, installation of decentralized mechanical ventilation device at every single unit in an apartment complex with more than 100 units has been common practice. However, the survey performed in this research reveals that a number of heat recovery ventilators are not operated correctly by residents. First of all, it is found that occupants usually avoidpowering their ventilators and just open windows in order to save their utility cost. However, inherent characteristics of high-rise buildings, such as highly air-tight envelopes and lack of operable windows make it difficult to meet the ventilation needs without mechanical ventilation. In addition, depending on occupants' decision in tuning on or off of ventilation units may be the biggest problem in current ventilation system operation. Consequently, the followings are suggested in this research for improving mechanical ventilation performance in high-rise apartment houses; fully automated ventilation system control for preventing uncertainty caused by manual operation, integration of renewable energy sources for realizing zero-energy ventilation system, and use of centralized ventilation system concept instead of decentralized one which is widely applied these days. Most of all, enhancing the people's level of understanding on high-rise building ventilation is very critical for effective ventilation system operation.

본 연구에서는 경기도 광명시흥지구를 대상으로 경관단위 유형분류를 통해 경관의 생태적, 휴양적 측면에서의 가치평가를 수행한 이후 이에 기초한 개선방안을 제언해보았다. 연구결과를 요약하면 다음과 같다. 경관단위 유형분류 결과 대분류 9개, 중분류 26개, 소분류 59개로 분류되었다. 생태적 측면에서의 1차평가 결과 I등급은 총 13개 유형으로 분석되었으며, 2차평가 결과 생태적 측면에서 특별한 의미를 가진 경관단위(1a, 1b)는 59개 공간으로 조사되었다. 휴양적 측면에서의 1차평가 결과 I등급은 총 15개, 2차평가 결과 양적 측면에서 특별한 의미를 가진 경관단위(1a, 1b)는 56개로 분석되었다. 가치평가 결과에 기초한 개선방안 설정 결과, 산림의 경우 생태적 측면에서는 계획지표“보전지역”을 적용하였으며 휴양적 측면에서는 계획지표 “자연체험 및 휴양 보전지역”을 적용하였다. 이러한 본 연구의 결과는 자연경관이 우점하고 있는 공간에 대한 다양한 개발계획 시 개발과 보전이 조화를 이룰 수 있는 경관계획 또는 생태관광계획 수립 시 중요한 기초자료로 활용 가능할 것으로 사료된다. In this study, after performing a valuation in terms of ecological and recreational aspects of the landscape through the type classification of landscapetope in Gwangmyeong-siheung district, Gyeonggi-do, we suggested improvement plans based on this. The summary of the research results is as follows. As a result of the landscapetope type classification, it was classified into 9 major categories, 26 middle categories, and 59 sub categories. As a result of the first evaluation in terms of ecology, the I grade was analyzed as a total of 13 types, and as a result of the second evaluation, 59 landscapetopes (1a, 1b) with special significance in terms of ecology were investigated. As a result of the first evaluation in terms of recreation, a total of I grades were analyzed, and as a result of the second evaluation, 56 landscapetopes (1a, 1b) that had special significance in terms of quantity were analyzed. As a result of setting improvement plans based on the valuation results, in the case of forests, the planning index “conservation area” was applied in the ecological aspect, and the planning indicator “nature experience and recreation conservation area” was applied in the recreational aspect. The results of this study are considered to be useful as important basic data when establishing a landscape plan or an ecotourism plan that can harmonize development and conservation in various development plans for spaces dominated by natural landscape.

This paper investigates the energy saving potentials of a dedicated outdoor air system (DOAS) applied to a highrise apartment building. As for a typical 132-㎡ apartment unit, two different HVAC systems; centralized DOAS-Ceiling Radiant Cooling Panel and decentralized Energy Recovery Ventilator-Packaged Air Conditioner were installed. Transient behavior and control characteristics of each system were modeled numerically using a commercial equation solver program, and annual cooling coil load and heating load reduction potentials were compared. The research shows that DOAS-Ceiling Radiant Cooling Panel system can reduce the cooling coil load over 21% annually compared with the current Energy Recovery Ventilator-Packaged Air Conditioner pair. In addition, over 40% of annual ventilation heating load can be reduced by use of DOAS.

BACKGROUND: The stabilities of the two alkaloidal insecticides of S. flavescens including matrine and oxymatrine are important factor to establish expiry date and usage manual for crop protection. However, the environmental stability of the compounds had not been studied with the extract and its commercial biopesticide. METHODS AND RESULTS: The environmental stabilities of the two alkaloids were performed with extract of S. flavescens, and its two commercial biopesticides both in controlled aquatic and soil conditions. The half-lives of the total matrines for the extract and its two commercial biopesticides were estimated over 200 days both under aerobic and anaerobic water condition. Under dry soil condition, the initial decay rates of the matrines were calculated 0.0804-0.1275 (t1/2 5.4-8.6 days), and the half-lives under wet soil condition were calculated 33.0-231 days. Total soil bacteria on the wet soil ranged 6.0-8.0 log CFU/g-soil during the experiments period. CONCLUSION: The aquatic mixture of the extract showed excellent stability both with the extract and its biopesticides, however, the stability of soil mixture were shorter than the aquatic mixture, suggesting that soil metal consider as a catalyst for the degradation of the two alkaloids.

Sundried salt was recently registered in food category in Korea in 2008, and food hygiene regulation only applied to several heavy metals and a few inorganic ions. In this report, we investigated the residual amounts of tricyclazole, a highly concerned contaminant from agricultural activity, and estimated their daily intake and hazard index. All 60 sundried salts were collected by region, and qualitatively and quantitatively were analyzed with GC-NPD. In this investigation, only three samples were confirmed the residual tricyclazole in sundried salts. Their maximum residue was 1.7 μg/kg, and their estimated average daily intake was 2.40 × 10<SUP>?8</SUP>~6.22 × 10<SUP>?8</SUP> mg/kg-day. From these results, HI of tricyclazole for sundried salts was 7.53 × 10<SUP>?7</SUP>~2.07 × 10<SUP>?6</SUP> for Koreans, and the values were not considered as serious risk issues currently.
