This study is to make the preservation plan for sustainable preservation restoration of Namsa-Yedamchon, Sancheong-gun, Gyeongsangnam-do through analyzing the site's characteristics and prototype landscape. Namsa-Yedamchon proudly presents ancient traditions and various historic resources. And several development plan and projects associated with historic resources of this site are in progress. Therefore, it was carried out to make master plan of Namsa-Yedamchon for preserving various prototype landscape. To achieve this, literature search, field survey, local residents' interview and the estimation of value on each prototype landscape were carried out. In literature search, it was analyzed to the previous studies related to this study and past data was collected like past picture, antique books, articles and so on. In field survey, it was carried out to analyze the present condition and the problems of prototype landscape in this site. In addition, the progress of landscape change in this site was analyzed through local residents' interview. The estimation of value on each prototype landscape was carried out to set up the appropriate preservation directions and preservation scope through selecting more important prototype landscape among them. Through these steps, the master plan was deducted and it was divided into 3 type; preservation conservation zone, restoration maintenance zone and renovation utilization according to landscape components, preservation scope, surroundings and so on.

본 연구는 대상자의 수가 적고 연구가간이 짧아 연구 결과를 일반화하기에 제한점이 있으나 원예치료프로그램이 그룹 홈 청소년의 자아존중감에 미치는 영향을 검증한 결과 유의함을 나타내었다. 이는 살아있는 식물을 매개체로 오감을 만족시키므로 창작활동을 통해 자기표현을 함으로 자긍심을 가질 수 있도록 하였으며, 흥미 있고 기분이 상쾌해지는 아름다운 꽃과 식물 기르기를 통해 그룹 홈 청소년들에게 정서적으로 안정감을 주었으며 자기가 완성한 작품을 남에게 선물을 하므로 상호작용이 이루어져 대인관계와 자기존재의식이 확립이 되는 기회를 주므로 원예치료가 청소년 자아존중감의 향상에 영향이 있는 것으로 판단된다.

This study was carried out to investigate the inhibitory effect of Angelicae Dahuricae Radix (ADR) extract on chronic obstructive pulmonary disease (COPD) induced by cigarette smoke condensate (CSC) and lipopolysaccharide (LPS) in mice. COPD was induced by intratracheal instillation of LPS and CSC 5 times for 12 days; this increased airway hyperresoponsiveness (AHR) and inflammatory cells in bronchoalveolar lavage fluid (BALF). ADR extract was administered orally at a dose of 50 and 200 mg/kg. The concentration of imperatorin, a major component of ADR and therefore used as a measure of quality control, was 0.098%±0.018%. Treatment of the mice with ADR extract (50 and 200 mg/kg) alleviated AHR and reduced inflammatory cell counts. Treatment with cyclosporin A (CSA; 10 mg/kg) also modulated AHR and reduced inflammatory cells effectively. Compared with CSA treatment, treatment with ADR (50 mg/kg) extract reduced neutrophil and CD4+/CD3+ cell counts by 22.67% and 44.92%, respectively. In addition, compared with CSA treatment, treatment ADR 200 mg/kg reduced neutrophils, CD4+/CD3+ cells and CD8+/CD3+ cells, by 32.10%, 83.17% and 82.11%, respectively. These results indicate that ADR extract may have an inhibitory effect on COPD induced by LPS and CSC in mice.

본 논문의 목적은 즈비카우스키(Lawrence Zbikowski)와 에버렛(Walter Everett)의 연구 들을 검토하여 가곡 분석의 한 방법론을 도출하고 이를 리스트의 가곡 《오 사랑하라》(O lieb)의 분석에 적용함으로써 그 효용성을 증명하는 데에 있다. 즈비카우스키는 개념적 혼성 이론(Conceptual Blending Theory)을 가곡 분석에 적용시켜 음악과 가사의 상호작용을 통 해 만들어내는 새로운 의미 구성의 양상을 탐구하였다면, 에버렛은 주로 쉔커식 분석에 의존 하면서 음악 표면적 사건 뿐 아니라 깊은 층위에서의 음악적 사건들을 시적 내용과 결부시키 는 분석을 시도하였다. 필자는 실제적인 음악 분석을 통해 가사의 내용과 결부시킬 수 있는 음악적 특징들을 찾아내는 데에 있어서는 에버렛의 방법론을, 음악적 특징들을 시적 내용과 연결시켜 설명하는 작업에는 즈비카우스키의 방법론을 발전적으로 수용함으로써 종합적이 고 체계적인 분석모델을 제시하고자 하였다.

강섬유보강 초고성능 콘크리트(UHPC)는 압축강도가 200MPa에 이르고, 강성 및 인성이 크기 때문에 이를 이용하면 구조 부재를 얇고 가볍게 설계하는 것이 가능하다. 본 논문은 UHPC를 교량의 바닥판 슬래브에 적용하기 위해서 뚫림전단(punching shear)에 대한 저항능력을 평가한 것이다. 6개의 정사각형 슬래브를 제작하여 4변 완전고정 상태에서 뚫림전단 실험을 수행하였다. 슬래브의 두께는 40mm와 70mm였고, 재하판의 형상비는 1.0~2.5 범위였다. 40mm 실험체는 최대하중 이후에 연성적인 변형률 연화구간이 길고, 70mm 실험체는 상대적으로 더 취성적인 뚫림파괴를 보였다. 기존의 여러 뚫림전단강도 평가식을 이용하여 실험결과를 분석하였는데, 두께가 작은 40mm 실험체에서는 DuctalⓇ 및 JSCE의 식이, 그리고 70mm 실험체에서는 Harajli et al. 및 ACI-DuctalⓇ의 제안식이 상대적으로 실험에 근접한 값을 예측하였다. 그러나 전반적으로 실험결과를 잘 예측하지 못하였으므로 실제 파괴메커니즘에 근거한 새로운 식을 제안하였다. 새로 제안한 식은 실험결과를 비교적 잘 예측하는 것으로 나타났다.

This study was performed to enhance antifungal activity of anthracnose in chili pepper by nanopaticles of thiamine di-lauryl sulfate (TDS) through high pressure homogenization process. Yield of TDS was 79.14% by reaction of thiamine hydrochloride and sodium lauryl sulfate. TDS nanopaticle solution was manufactured through high pressure homogenization process. The turbidity of nanoparticles solution was increased with increasing the concentration of TDS, and nanoparticles solution of 100 ppm was showed the highest turbidity with absorbance of 3.212. The size of nanoparticles solution was measured as average 258.6 nm by DLS. Nanoparticles solution of 100 ppm showed growth inhibition activity with higher than about 80% compared to the control group against Colletotrichum gloeosporioides. Finally, nanoparticles solution was increased effectively the penetration of the TDS nanopaticles on attached cell membrane of hyphae and started to destruct the cells under microscope observation. Consequently, we suggested that the TDS nanoparticle solution by high pressure homogenization process might be suitable biochemical pesticides for improving the antifungal activities against anthracnose in pepper.

This study was carried out to investigate whether Chrysanthermum zawadskii var. latilobum Kitamura (C. zawadskii) extracts has an inhibitory effect against the mutagenicity by cigarette smoke condensates (CSC). C. zawadskii was extracted with 70% ethanol and the yield was 18.5%. We further fractioned 70% ethanol extract sequentially to diethylether, chloroform, dichloromethane, and aqueous water, and gained the yield of 17.5%, 5.6%, 5.8%, 32.8% and 35.5%, respectively. In the Ames test, there was no mutagenic effect of crude extract and its solvent fractions up to 2 mg/plate toward Salmonella typhimurium TA 98 with or without S-9 mix metabolic activations. On the contrary, the crude extract showed an inhibitory activity against the mutagenicity of CSC in the presence of S-9 mix metabolic activation. Diethyl ether layer among five solvent fractions showed the highest inhibitory activity. The inhibitory activity of diethyl ether fraction was also increased in a dose-dependent manner and the inhibitory rate was about 97.7% at the concentration of 1 mg/plate. In this study, we conclude that crude extract of C. zawadskii itself is potentially safe for mutagenicity, and the diethyl ether fraction has an inhibitory effect against the mutagenicity of CSC.

Industrial natural ventilation systems consist of gravity ventilator, the high/low windows and doors. Especially, the high windows play an important role in the industrial natural ventilation systems. Generally speaking, industrial high windows are divided into 3 types; louver type, 45° open type and 90° open type. This study was numerically and experimentally conducted. Three types of windows were tested to know the ventilation characteristics and estimate the ventilation efficiencies. Numerically, computational fluid dynamics software (AIR PAK Ver. 2.0) was used to observe the flow characteristics inside the industrial building and the concentration contours generated by the tracer gas method. Experimentally, the flow visualization technique and the tracer gas method were applied with the model building to characterize the flow pattern inside the model building and to estimate the ventilation efficiencies with the different windows. It was found that 90° open type window was most effective for the discharge of pollutants from the industrial building. On the other hand, the louver type window was found to be less effective than any other windows.
