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.

비료제품에는 의도적 혹은 비의도적으로 농약으로 등록된 indole-3-acetic acid (IAA) 및 indole-3-butyric acid (IBA)성분에 대한 잔류 가능성이 꾸준히 제기되고 있으나, 생장조정제가 아닌 비 료제품에서 mg/L 수준의 옥신류 잔류분석법이 마련되어 있지 않았다. 따라서, 본 연구에서는 생체시료에 미량 잔류하는 IAA 및 IBA 분석에 사용되어 온 liquid chromatography-mass/mass spectrometry (LC-MS/MS)와 gas chromatography-MS 기기분석 법을 활용하여 농축 액상비료제품에 적용할 수 있는지 조사하였으며, 액상 비료제품에 적용 가능한 정밀기기 분석법을 개발하고자 하였다. 수용액 상태의 시료에서 식물 생장호르몬인 IAA 와 IBA를 가장 손쉽게 정제할 수 있는 방법으로 hydrophile-lipophile balance (HLB) solid phase extraction를 활용하였으나, 제한된 조건에서 LC-MS/MS를 통한 정량분석은 적합한 회수율을 확보하지 못하였고, 정성분석만 가능함을 확인하였다. 반면, 비료제품 250배 희석액을 사용하여 HLB 정제, trimethylsilyl chloride을 이용한 methylation을 통한 GC-MS 분석에서는 검출 한계 1.4 mg/L과 93-107%의 회수율로 액상 비료제품에서 IAA 와 IBA 정량분석법을 확립할 수 있었다. In here, we investigated the quantitative analysis method of indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) with liquid chromatography-mass/mass spectrometry (LCMS/ MS) or gas chromatography-MS. Two ways of clean-up pr℃ess were investigated for LC-MS/MS instrumental analysis of IAA, but both a simple dilution and hydrophile-lipophile balance (HLB) solid phase extraction (SPE) were not met the optimal recovery rates for quantitative analysis. On the other hand, the clean-up method for GC-MS was finally optimized through HLBSPE from 250-folds diluted sample and methylation with trimethylsilyl chloride in methanol for 4 h. The limit of detection for methyl ester of IAA and IBA were both 1.4 mg/L, and recovery rates showed 93-107% from the concentrated liquid fertilizer.

The objective of this paper is to show the possibility of demand-controlled ventilation(DCV) using the Korean ventilation standard for apartment houses. A numerical model for predicting realtime occupant number and CO2 concentration under given conditions is developed using a commercial equation solver program. It was found that the current ventilation standard causes unstable ventilation system control in DCV application under CO2-DCV. It is because the ventilation rate(per person) used in Korea is the sum of the outdoor air required to remove or dilute air contaminants generated by both occupant and building itself. It was also found that current Korean ventilation standard modified as a form of ASHRAE standard enhances applicability of the current ventilation standard to the DCV approach.

A dedicated outdoor air system (DOAS) comprised of enthalpy wheel, cooling coil, sensible wheel and supply/exhaust fan is able to decouples ventilation and air-conditioning functions and/or sensible and latent load functions. It removes the entire latent load and a portion of the sensible load inside a conditioning zone using 100% outdoor air ventilation. The remaining sensible load is accommodated by a parallel mechanical cooling system. According to the literature, a DOAS based centralized ventilation system shows good potentials for using in high-rise multi-family houses. The main object of this paper is to develop a simple computer program which can be used in the preliminary design phase of a DOAS applied to high-rise apartment buildings.

본 연구에서는 식물을 원료로 하여 제조된 발효식품들 중 지금까지 BAs에 대한 잔류분석연구가 진행되지 못하였던, 식품군들에 대해 BAs 잔류분석을 실시하였다. 조사대상 식품군으로는 식물 발효진액, 장아찌, 막걸리, 흑마늘, 발효차를 선정하였으며, 발효진액, 막걸리, 흑마늘, 발효차는 HIS, TYR, PUT, CAD, PHE 5종 BAs 의 총 함량이 1,000mg/kg을 초과하지 않았으나, 장아찌시료에서는 19.2?1,214 mg/kg으로 검출되었다. 이러한, 장아찌류의 고잔류 BAs는 간장과 된장 등 원료 장류에 의한 영향이 높을 것으로 사료되며, 장아찌에 대한 BAs 연구는 원료 및 제조 특성별 잔류 분석연구가 보완되어야 할 것이다. Ten major residual biogenic amines including toxic histamine and tyramine were investigated in the plant-based minor Korean fermented food. From the analyses of pickled vegetables, fermented vegetable extracts, fermented tea, black garlic and herbal rice wines, more than 100 mg/kg of histamine were found in pickled soy leaf and pickled mulberry leaf, and also over 1,000 mg/kg of total biogenic amines were found in pickled soy leaf. No sample was found over in black garlic, fermented tea, fermented vegetable extracts and herbal rice wine, less than 100 mg/kg of histamine and/or 1,000 mg/kg of total biogenic amines were observed. Interestingly, all the tested rice wines were found to be over 100 mg/kg of agmatine residue.

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.

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.
