본 연구는 거리화단 화훼경관 조성 전·후의 스트레스 변화 를 알아보기 위하여, 순창 소재의 경찰관 총 18명을 대상으로 타액 채취 및 설문조사를 실시하였다. 생리 측정은 타액 코르 티솔, 혈압, 심리 측정은 식물 재배 활동 수준, 스트레스수준, 거리화단 화훼경관에 대한 간이 SD 감성을 측정하였다. 타액 코르티솔, 혈압의 사전/후 비교는 대응표본 t-test, 타액 코르 티솔, 혈압의 성별에 따른 집단간 사전/후 비교는, 독립표본 t-test, 스트레스수준, 간이 SD는 윌콕슨 부호 순위 검정 등으 로 분석하였다. 화훼경관 조성 전보다 조성 후 총 코르티솔 수 치가 낮아졌고, 식물 재배 활동 수준은 높아졌으나 통계적 유 의성은 없었다. 혈압은 여자의 경우 거리화단 화훼경관 조성 전과 조성 후 모두 정상 혈압이었고, 남자의 경우 거리화단 화 훼경관 조성 전 고혈압 전단계에서 조성 후 주의혈압으로 낮 아지는 긍정적 효과가 있었다. 거리화단 화훼경관 조성 전·후 의 스트레스수준을 총 4단계(총 4단계: 단계가 높을수록 스트 레스가 높은 수준임)로 문항 전체의 총합 수치로 알아본 결과, 화훼경관 조성 전에는 4단계(50.0%), 2단계(38.9%), 3단계 (11.1%) 순이었으나, 조성 후에는 4단계(44.5%), 2, 3단계(각 22.2%), 1단계(11.1%) 순으로 거리화단 화훼경관 조성 전에 는 1단계(정상적인 스트레스 상태로 스트레스요인 자체가 심 각하지 않거나 좋은 스트레스로 받아들인 경우)가 0%에서 조 성 후 11.1%로 높아졌다. 화훼경관 조성 전·후 SD법을 이용 하여 쾌적감, 자연감, 그리고 진정감에 대해 평가한 결과, 화 훼경관 조성 후 쾌적감, 자연감, 진정감이 높은 것으로 나타났 다(p<.05). 거리화단 화훼경관에 따른 식물 재배 활동 수준과 주요 변수간의 상관관계를 알아본 결과, 화훼경관 조성 후 식 물 재배 활동 수준과 스트레스수준, 스트레스수준과 진정감은 부(-)의 상관관계, 식물 재배 활동 수준과 쾌적감, 자연감, 진정 감과는 0.5 이상의 높은 정(+)의 상관관계가 있었다(p<.05). 따라서 식물 재배 활동 수준이 높아질수록 쾌적감, 자연감, 그 리고, 진정감은 높아지고, 거리화단 화훼경관이 없는 공간보 다 화훼경관이 있는 공간에서 쾌적감, 자연감, 그리고 진정감 을 더 크게 느끼는 것으로 판단되었다. 본 연구에서 거리화단 화훼경관을 통하여 고위험군의 높은 스트레스는 줄여주고 식 물에 대한 흥미, 관심과 심리적 안정효과는 높여 줄 수 있는 유용한 가능성이 있을 것으로 생각되었다.

나리(Lilium spp.)는 절화, 정원 식물 및 화분 식물과 같은 관상용 가치로 인해 가장 중요한 화훼 작물 중 하나이다. 나 리는 연작으로 인한 환경 스트레스에 민감하며, 환경 스트레 스의 원인 중 하나로는 염 스트레스가 있다. 본 연구는 분홍 색 오리엔탈 나리 'Medusa', 'Lake Carey', 'Ovada'의 생 육 시기별 염스트레스에 따른 표현형 및 색 관련 화합물 함 량 변화를 조사하였다. 염 처리는 생육 시기에 따라 다양한 처리기간(무처리, 발아 전, 발아 후, 전체 생육기간)에 주 1 회 염(8dS･m-1)처리를 실시하였다. 생육 시기별 염스트레스 에 의한 개화의 차이가 있었지만, 전체 생육기간동안 염 스 트레스 처리시 모든 품종에서 개화가 이루어지지 않았다. 염 스트레스 처리 시기에 따라 초장과 꽃의 크기가 감소율이 달 랐으며 'Medusa', 'Lake Carey'는 발아 후 염 처리에서 정 상 개화하였다. 또한, 염스트레스는 꽃과 같은 식물에서 생성 되는 색 관련 화합물인 페놀과 플라보노이드 함량도 시기별 로 차이가 있었다. 품종마다 차이는 있지만, 발아 전이 발아 후 염 처리보다 총 페놀과 총 플라보노이드 함량이 더 낮은 것을 확인하였다. 이 결과는 생육 시기에 따라 염 스트레스 에 의한 나리의 표현형과 화색 관련 화합물의 함량의 변화에 차이가 있었으며 생육초기 염스트레스에 의한 피해가 높은 것으로 판단된다.

본 연구는 절화용 튤립(Tulipa spp.) 4품종을 대상으로 재 식밀도에 따른 생장과 발육 특성을 알아보고 광이용효율을 분 석하여 우리나라에서 튤립 촉성재배시 필요한 기초자료를 얻 고자 실시되었다. 절화용 튤립 ‘Novi Sun’, ‘Timeless’, ‘Il de France’, ‘Dow Jones’ 4품종을 대상으로 구근용 재배 상자 (가로×세로×높이; 60cm×40cm×20cm)에 상자당 48, 70, 96개의 구근을 정식하여 저온처리 이후 비닐하우스로 운반되 었다. 그 결과, ‘Novi Sun’과 ‘Timeless’는 온실 이식 이후 35 일 만에 수확되었으며 ‘Il de France’와 ‘Dow Jones’는 그보 다 빠른 30일 만에 수확되었다. 모든 품종에서 재식밀도가 증 가할수록 생체중, 줄기 직경, 엽면적이 감소하였다. 정상개화 율은 96bulbs/box 처리에서 특히‘Novi Sun’ 32.7%과 ‘Timeless’ 4.7%로 감소하였으며 이 두 품종에서 줄기와 꽃의 건물중이 크게 감소하는 것으로 나타났다. 광이용 효율과 밀접 한 지표인 엽면적지수는 재식밀도가 높아질수록 증가하였다. 광합성 효율은 ‘Novi Sun’과 ‘Timeless’의 경우 저광도에서 재식밀도에 따라 큰 차이가 없는 것으로 나타났다. 엽면적 감 소와 형태적인 변화가 작은 ‘Il de France’과 ‘Dow Jones’에 서 광합성 효율이 크게 변화하였다. 재식밀도에 따라 다양한 생육 반응은 유사한 경향은 있으나 품종에 따라 광합성 효율과 동화산물의 분배가 크게 달라지는 것으로 나타났다. 튤립 촉성 재배 시 정상적인 꽃의 발달과 생육 확보를 위해서는 충분한 재식 간격을 확보할 수 있는 재식밀도로 정식해야 한다.

본 연구에서는 파프리카(Capsicum annuum L)의 소비증 가 및 홍보를 위해 응답자 소비성향과 파프리카의 인지도를 분석하였다. 의미분별법에 따른 파프리카에 대한 감성반응을 바탕으로 선호도 및 충성도와의 상관관계를 분석하였다. 설 문조사는 2022년 1월부터 2월까지 일반인 155명을 대상으로 임의추출법을 통하여 조사하였으며, 잘못된 답변을 한 13건 을 제외하고 총 142명의 설문지를 분석하였다. 파프리카의 인 지도 9개의 문항을 요인분석을 통하여 재구성한 결과 ‘식미 성’, ‘이용성’, ‘경제성’의 3요인으로 구성되었다. 9가지 문항 중에서 파프리카에 대한 인지도를 문항별로 알아본 결과로 ‘파프리카가 건강에 좋을 것 같다’는 문항의 긍정적 답변이 92.3%의 가장 높은 비율을 나타냈다. 파프리카의 형태 선호 도는 뭉툭한 유형이 가장 높았고, 그 다음은 소형(Mini) ˃ 원 뿔형(Conical) 순으로 선호하는 것으로 나타났다(p < 0.001). 색채 선호도는 노란색 파프리카를 가장 선호하는 것으로 나타 났고, 그 다음은 오렌지색 ˃ 적색 ˃ 녹색 순으로 선호하는 것으 로 나타났으며 통계적으로 유의하였다. 파프리카의 이미지를 보고 느끼는 감성 반응은 3가지 형태간, 그리고 4가지 색채간 통계적으로 유의한 차이를 보였으며, ‘밝은’, ‘맑은’, ‘활기찬’ 이 대표 이미지 감성어휘로 나타났다. 파프리카 이미지에 대 한 감성 2요인(평가적인 요인, 정서적인 요인)과 통제변수인 인구통계학적 변수가 선호도에 미치는 영향을 알아보기 위해, 더미변수를 포함한 다중회귀분석을 실시한 결과, 파프리카 이미지에 대한 평가적인 요인이 높을수록, 그리고 주부의 경 우 선호도는 높은 것으로 나타났다. 또한 파프리카의 인지도 3 요인(식미성, 이용성, 경제성), 선호도, 한국판 삶의 질과 통제 변수인 인구통계학적 변수가 충성도에 미치는 영향을 알아보 기 위해, 더미변수를 포함한 다중회귀분석을 실시하였다. 그 결과, 파프리카 선호도와 삶의 질이 높을수록, 파프리카 인지 도 중에서 식미성 요인, 이용성 요인이 높을수록 충성도는 높 은 것으로 나타났다. 또한 경제성 요인 즉 가격이 높을수록, 그 리고 응답자의 월평균 소득이 낮고, 농림수산업 종사자의 경 우 충성도는 낮은 것으로 나타났다. 설문 응답자들의 충청도 에 영향을 미치는 변수들 중에서 파프리카 선호도는 43%로 가장 높은 설명력을 지니며 가장 영향력 있는 변수로 나타났 다. 이러한 결과에서 파프리카의 형태와 색채 선호도에 대해 구명하는 것은 매우 중요한 것으로 판단되었으며, 최근 파프 리카가 건강에 좋을 것이라는 인식이 높아지고 있다는 것은 앞으로 내수 증가에 긍정적 요인이 될 것으로 생각되었다. 또 한 3가지 형태의 파프리카 중에서 선호도가 가장 높게 나타났 던 뭉툭한 유형의 노란색 파프리카를 생산, 홍보를 지향하여 소비자의 구매 성향에 적합한 파프리카의 재배를 늘리는 것도 중요할 것으로 판단되었다. 추후 파프리카의 소비 촉진을 위 하여 소비자를 대상으로 한 지속적인 연구와 홍보 지원 활동 등을 통하여 파프리카에 대한 소비자 인지도를 높일 필요가 있다고 생각된다.

Pest control treatment was carried out using an unmanned automatic pesticide spraying system that can spray pesticides on crops while moving autonomously to control pests in vegetable greenhouse. As a result of examining the control effect on tomato and strawberry on thrips (Frankliniella occidentalis) and greenhouse whitefly (Trialeurodes vaporariorum) pests, 85.6% of yellow flower thrips were found in tomatoes and 87.5% in strawberries, and 81.7% (tomato) and 80.6% (strawberry) of greenhouse whitefly. In addition, the control effect according to the pesticide treatment method showed a control effect of 81.7% of the chemical spraying treatment by manpower and 83.9% of the automatic moving pesticide spraying treatment (F=22.1, p < 0.001). When comparing the control effect between the two treatment sections, there was no significance, but the automatic transfer spraying treatment showed a 2.2% higher effect. On the other hand, as a result of comparing the spraying time of the drug, the automatic unmanned control sprayer had a spraying time of 5 min/10a, which took about 25 min less than the conventional manpower spraying time of 25－30 min/10a. Based on these results, it was judged that the automatic transfer spraying method could be usefully used for efficient pest control in the facility greenhouse during the peak period of development.

The attraction effects of light emitting diode (LED) trap to Spodoptera exigua and Spodoptera litura adults were evaluated in greenhouse and compared with those of no light trap, which is typical used in commercial trap. At this time, in order to attract these two species of moths, sex pheromone traps were installed at the top side according to the degree of tomato growth inside the tomato cultivation greenhouse around the LED trap. In addition, two types of light-emitting traps (420 nm, 470 nm) were installed in the greenhouse at 1/40 m2, respectively. Also two sex pheromone were installed inside of the greenhouse according to the height of the tomato plants. 10 days later, Blue-light trap(BLB, 470 nm wavelength) was 3.1－3.5 times more attractive than Violet-light trap(VLB, 420 nm wavelength) in S. exigua (105.6 ± 7.3) and S. litura (42.0 ± 3.1) respectively, whereas the no-light trap was little attractive to S. exigua (33.7 ± 2.8) and S. litura (12.0 ± 1.5). On the other hand, after the installation of the sex pheromone trap and the LED trap, there was no damage to S. litura (Fabricius) and S. exigua in the pesticide-free area, indicating a high possibility of control. At this time, the operating cost of the two types of LED traps was 80 won/m2 per unit area, and it was confirmed that both types of moths could be controlled. In addition, as a result of confirming the number of two types of moths caught in the sexual pheromone trap and two types of LED traps after 4 months, it was judged that eco-friendly control was possible as more than 373 moths/trap were attracted to the two types of moths.

This study was conducted to investigate the change of workers physiology and sensitivity according to the plant decoration activity using electroencephalographic (EEG), electrocardiogram, and semantic differential (SD) methods on 31 male and female workers in their twenties. Plant decoration activity and writing documents on a computer (WDOC) were carried out for 10 minutes each. The relative slow alpha power spectrum (RSA) has been highly exhibited at most measurement points at plant decoration activity compared to WDOC, and ratio of alpha to high beta spectrum (RAHB) was higher in the parietal lobe responsible for visual function in charge of visual function and showed stable and relaxed effect with little stress or tension. In addition, the relatively fast alpha power spectrum (RFA), which is responsible for visual function, after WDOC was higher than after plant decoration activity in the left parietal lobe (P <.05). Although not statistically significant, the relative high beta power spectrum (RHB) and the ratio of mid beta to theta (RMT), which are stress concentration indexes with tension, were highly regarded as a whole when performing WDOC. There was little difference in heart rate between after both activities. However, high frequency (HF) component indicating parasympathetic nervous system activity was more highly active after WDOC than Planting decoration activity, and the low frequency (LF) component indicating sympathetic nervous system activity tended to be lower after WDOC than after planting activity meaning that plant activity have a sense of stability than WDOC and these results were similar to brain wave analysis. In addition, the sense of comfort, naturalness, calm were significantly higher when the plant decoration activity was performed than when the WDOC was performed in the SD emotional vocabulary survey. These results could be interpreted that plant decoration activity induced more physiologically and psychologically stability and relaxation than WDOC, and enhanced attention ability in appropriate awakening state.

This study was taken place to find out the psychological change with comparing before and after the experience of installation of indoor garden with 55 of subjects out of 62 subjects. More than 50% of subject answered that the garden management would be difficult before they experience the installation but the pressure was decreased while the interest of plants and landscape increased, however, the burden of management decreased and the interest in the kinds of plants and landscape design tended to increase after the experience of the installation. The psychological effect of indoor garden of workers was significantly increased with the question of “Indoor garden improves effect of air cleaning.” after the experience of installation and the loyalty was statistically increased with the question of “Intend to invest more fund to purchase indoor plant” (p <.05). As a result of the comparison of two psychological indicators, the recovery index of the state according to experience of indoor gardening was significantly higher after experiencing the indoor garden than before the indoor gardening experience. As the result of sensibility evaluation of pleasant, natural and calm with semantic differential method, workers feel more of them with the indoor garden. In addition, the loyalty was statistically significantly higher in the question “I would be willing to invest more in plant purchase” after experiencing the composition indoor garden (p <.05). This result is similar to the result that the resident’s recovery index, pleasantness, calm feeling, and emotional index are higher the indoor garden in public resting area with indoor garden than without indoor garden. With this study, the perception of indoor garden changed as a result of the worker’s experience of indoor gardening in the workplace and the view of the indoor garden created by the workers. As the psychological healing effect of indoor garden increased, increase in the cost investment for the emotional health promotion of the workers is expected to have a positive effect on the increase of the indoor garden.

To evaluate the protective effect of Ajuga multiflora BUNGE (AMB) extract on the toxicity of lead acetate (LA), environmental pollutant, cell viability was measured by XTT assay using cultured NIH3T3 fibroblasts. And also, the effect of antioxidant, butylated hydroxytoluene (BHT) on LA-induced cytotoxicity was analysed. For the protective effect of AMB extract on LA-induced cytotoxicity, NIH3T3 fibroblasts were pretreated with 80 or 90 μg/mL of AMB extract for 2 hours before the treatment of LA. And also, the antioxidative effects of AMB extract against LA-induced cytotoxicity were assessed by DPPH-radical scavenging activity, superoxide dismutase (SOD)-like activity and inhibitory activity of lipid peroxidation (LP). In this study, LA significantly decreased cell viability dose-dependently compared with control, and then XTT50 value was determined at 46.1 μM of LA. In the effect of BHT against LA-induced cytotoxicity, it effectively prevented toxic effect of LA by the significant increase of cell viability. In the protective effect of AMB extract on LA-induced cytotoxicity, it significantly increased cell viability which was decreased by LA-induced cytotoxicity, and also it showed the antioxidative effects such as DPPH-radical scavenging activity, SOD-like activity and inhibitory activity of LP. From these results, it is suggested that the cytotoxicity of LA is involved in oxidative stress, and AMB extract effectively prevented the cytotoxicity induced by LA via an antioxidative effect. Conclusively, the natural substance such as AMB extract may be alternative resources for the prevention or treatment of diseases related with oxidative stress.

분화활동에 따른 인간의 생리 및 감성변화를 알아보기 위해 20대 피험자 남녀 총 31명을 대상으로 뇌파, 심박변동성, SD(semantic differential)법을 실시하였다. 실험은 각각 10분씩 유리용기(지름 30cm)에 분화식물을 장식하는 작업, IT활동(문서 작성)하는 작업을 실시 하고 사전/후 측정하였다. IT활동(문서 작성)을 대조구로 하여 분화장식활동을 비교한 결과, IT활동보다 식물활동을 하였을 때 상대적 느 린 알파파(RSA)가 대부분의 측정지점에서 높게 나타났고, 알파/빠른 베타(RAHB)가 시각기능을 담당하는 두정엽(P3, P4)에서 높게 나타 나 스트레스나 긴장감을 거의 동반하지 않은 안정, 이완효과가 있는 것으로 나타났다. 또한 분화장식활동을 한 후보다 IT활동(문서작성)을 한 후 시각기능을 담당하는 상대적 빠른 알파파(RFA)가 좌반구 두정엽 (P3)에서 높게 나타나 몰입도가 높은 것으로 나타났다. 그러나 IT활 동(문서작성)보다 분화장식 활동을 했을 때 뇌활성도(SEF 90)가 좌반구 측두엽(T3), 우반구 후두엽에서 통계적으로 유의성있게 높게 나타 나 스트레스를 동반한 상태에서 고도의 집중력 효과가 있는 것으로 볼 수 있었다. 분화장식활동과 IT활동을 한 후 심박수의 차이는 거의 나 타나지 않았으나 IT활동보다 분화장식 활동에서 자율신경계활동 중 부교감신경계활성의 지표인 HF(high frequency)성분이 더 높게, 교감 신경계활성 지표인 LF(low frequency)성분은 IT활동보다 분화장식활동을 한 후에서 더 낮게 나타나 IT활동보다 분화장식활동이 안정감 을 갖는 경향을 보였으며 이러한 결과는 뇌파분석과 유사한 경향이었다. 분화장식활동과 IT활동에 따른 피험자 선호도는 분화장식활동 (4.00/5), IT활동(2.58/5)로 분화장식활동이 IT활동보다 통계적으로 유의성있게 높게 나타났다. 또한 SD 감성어휘조사에서 IT활동했을 때 보다 분화장식 활동을 했을 때 쾌적감, 자연감, 진정감이 유의성있게 높게 나타났다. 이는 분화장식활동이 IT활동보다 생리·심리적으로 안 정, 이완, 그리고 적절한 각성 상태에서 내적, 외적 주의집중력 향상 효과를 주는 것으로 해석할 수 있다. 따라서 식물을 활용한 분화장식활 동은 스트레스가 있는 대상자들에게 적용하는 것이 유용할 것으로 판단된다. 그러나 뇌활성도(SEF 90)이 IT활동보다 높게 나온 결과는 추 후 지속적 연구를 통해 긴장의 종류를 밝혀내야 할 것으로 생각된다.

The study was surveyed to 269 respondents for investigating psychological response to indoor foliage plants grouped by four type of design materials. 21 indoor foliage plants grouped as filler, mass, form, and line plant, are shown to each respondent for surveying the preference and emotion by SD (semantic differential) scale. It was statically significant that the filler plant group was the least preferred one between the indoor foliage plant and the preference of line plant group was the highest. In filler plant Scindapsus aureus is significantly favored, in mass plant Aglaonema crispum and Syngonium podophyllum, in form plant Ficus banghalensis in line plant Dracaena fragrans ‘Lemon Lime’, respectively. The green is the most preferred color of leaf and gray is the least one. When investigated on the major emotions felt with four types of indoor foliage plant with SD scale, filler plant felt as ‘Bright’, ‘Light’, ‘Pale’, mass plant ‘Warm’, ‘Sharp’, form plant ‘Simple’, ‘Luxurious’ and line plant ‘Sophisticated’, ‘Luxurious’, ‘Pleasant’, ‘Soft’ and ‘Fancy’, respectively. This result will be valuable when the indoor garden is designed with an indoor foliage plant.

This study was conducted to know the visual preference and emotional change for the cut-flower decoration at public indoor space by using vertical, horizontal, and round type which are generally used. The investigation was done with 173 participants of National Institute of Horticultural and Herbal Science in 3 indoor areas designed with cut-flower decoration and 1 area of public place without it, respectively. Psychological evaluation was analyzed with the visual preference of cut flower shape and Semantic Differential method. In addition, the general awareness, loyalty and importance for cut-flower decoration were investigated. Statistical analysis was carried out with paired t-test, one-way ANOVA, cross correlation analysis, and analysis of frequency. As the result of evaluating the emotion of subjects with Semantic Differential, the feeling of comfort, nature and calm were significantly high in the public indoor space with cut-flower decoration. When we surveyed the feeling for the 3 type of cut-flower decoration with 14 pairs of emotional vocabulary, the participants felt ‘tranquil’ and ‘comfortable’ in the public indoor space with horizontal and round shaped decoration while they felt ‘strong’ and ‘anxious’ in the space with vertical shaped decoration. The preference of decoration forms was significantly high with round > horizontal > vertical type in order and vertical shape was highly preferred in twenties and sixties groups compared to other types significantly. In conclusion, we could recommend that round type decoration can be used in indoor place where comfort and calm are required and vertical form will be appropriate for challenging and vibrant twenties and depressed sixties with ageing. This customized cut-flower decoration will improve the environment quality of employment.

This study investigates and analyzed the psychological effect of existence or non-existence of cut-flowers decoration in the conference place by the presenting eight colors of decorations (white, pink, blue, orange, red, green, purple, and yellow) to the participants, 103 numbers of genders. The measurement of psychological condition was carried out and compared with an attention recovery scale, profile of mood states (POMS) and semantic differential (SD method). In addition, paired t-test, One way ANAVA and Pearson’s correlation analysis were used for the statistical analysis. As the result of investigation for the general awareness of cut-flower decoration, the most priority is its color tone and 57.3% of participants which is the highest portion answered that the amount of annual investment for cut-flower decoration is 20,000～99,000 Won. According to the result of comparison for three psychological indexes, the attention recovery scale was significantly higher in the area with cut-flower decoration than the area without it. In POMS, it showed the negative emotions, such as, tension-anxiety, depression, confusion was low while the positive emotion like vigor was significantly higher in the area with cut-flower decoration than the area without it. In addition, the participants could feel the pleasant, natural and clam significantly more in the conference place with cut-flower decoration than the area without it. The order of color preference of cut-flower was Green > White > Pink > Blue > Yellow > Purple > Orange > Red with significant difference. Also, as the result of investigation for the color sensibility of its tone of the cut-flower decoration in conference place with SD method, the participants could feel ‘comfortable’ and ‘calm’ the most with green, white and blue decoration while ‘strong’, ‘vibrant’, ‘uneasy’ of feeling was shown the most in red and orange decoration and ‘warm’, ‘fancy’ in yellow. Based on the result of this study, the workers can have positive psychological effects by having cut-flower decoration or using appropriate colors with cut-flower decoration in the uncomfortable area, such as, conference place.

This study is conducted with the questionnaire survey of 174 participants to investigate the psychological effect of workers with the indoor-garden in lounge of public building. The measurement of mental state was investigated and compared with loyalty, attention restoration, profile of mood states (POMS) and semantic differential method (SD Method) while statistical analysis was compared and analyzed with paired t-test, frequency analysis, cross correlation analysis, one-way analysis of variance, and Pearson’s correlation analysis. As the result of analysis of three psychological index, the rate of attention of restoration to the worker was significantly higher in the area where the indoor-garden is installed than the area with no indoor-garden (p≦0.001). Emotional examination showed less negative emotions, such as, the tension, depression, anger, exhaustion or confusion while more positive feeling was vitalized in the area where there is indoor-garden in the lounge than the place with no garden. In addition, as the result of comparison for the index of emotion by gender, negative emotions of men decrease but positive feeling increase more than the group of women in the area where there is indoor-garden in the lounge than the place with no garden. As the result of evaluating the emotion of pleasant, natural and relax with SD method, worker might feel them more in indoor-garden of lounge. Detailed items of plant does not seem to affect to the loyalty in the interest of indoor-garden to the workers, however, behavioral element, such as, feasible investment-cost, provides extremely positive effect (p≦.05). Based on this study, the cognizance of healing effect, attention restoration, profile of mood state (POMS) and emotional quotient by the existence of indoor-garden can be concluded that it will provide the positive effects to diffuse indoor-garden and promotion of emotional health for the staff. In addition, indoor-garden can be practically used to reduce the stress and provide the stability of the indoor-staff.

The purpose of this study was to evaluate the effect of essential oil on wound healing rate, an epithelial attachment and collagen density in wound induced rat. This study was a 2×3 factorial design. Factors were treatment period (4 day and 8 day) and treatment type [saline (0.9% NaCl), tyrothricin, mixture of tea-tree, rosemary and melissa oil]. The samples were 24 rats with wound and randomly assigned to six groups of four rats per group. The dependent variables such as a wound healing rate, an epithelial attachment and a collagen density were measured. Dependent variables were statistically significant difference by the two treatment periods and the three treatment types (p<.001). There were not statistically significant interactions between treatment periods and treatment type in all dependent variables (p>.05). These findings will be provide bases to develope effective interventions for patients who have wound to manage their wound.

This study analyzed the questionnaire of 279 participants which counted 26 cases out of total 305 participants. It is organized to find out the influence of indoor-plants for green interior of psychological effect, general awareness and the color or shape of indoor-plants in dining/living area to the preference of consumers and emotional image. 74.6% of participants had the experience of purchasing the indoor-plants for green interior. As the result of general awareness of green interior, the most important factor when the green interior was organized was the shape of plants and the most selected possible amount of investment to the installation was less than 100,000 won which is not high enough. As the result of investigation on participant’s awareness of effect of indoor-plant, 99.3% of participants which was the highest portion answered ‘Indoor-plants improve the psychological stability’ from the selection of five kinds of indoor-plant’s effects. More than 50% of participants showed high interests to the green interior in dining/living area as they selected ‘Preferred’. Decoration of cut-flower and eruption are preferred as the design of dining area. The preference order of 5 types of colors for green interior was white> green> pink> yellow> red and showed significant difference. As the result of investigation on color sensitivity of green-interior area with Standard Deviation method, white and green stimulus group highly shows the emotion of “Clam” and “Comfortable”. In addition, red and pink stimulus group feels hard the emotion, “Fancy”. Cut flower decoration was highly preferred when living area is decorated with 76.6%. Also, there was significant difference in the shapes of green interior in living area with the order of horizontal> round>vertical. According to the result of study on emotional difference with green interior of living area with Standard Deviation, horizontal way has “Calm”, “Comfortable” while vertical provides “Heavy” and “Strong”. This study tries to provide the useful and positive possibility of design direction and improvement of consumption of indoor green-interior by understanding of psychological effect and awareness of indoor-plan.

This study was carried out to investigate the formaldehyde (FA) filtration pattern of additional media for indoor biofilter system. Dry pellet type activated carbon (PAC), activated clay (ACL), zeolite, diatomite, pumice and loess ceramic ball were tested. In the case of dry filter media, formaldehyde purification efficiency was the most excellent with activated clay and then was good with the activated carbon, diatomite, zeolite, and pumice order. PAC and ACL decreased the FA concentration with exponential pattern resulted from dynamic balance between emission and purification. Zeolite, diatomite, pumice, and loess ceramic ball showed high filtration rate at initial time and then increased FA concentration result from breakthrough. PAC, zeolite and diatomite could be recommended as additional filter media for biofilter system considering FA filtration and breakthrough characteristics. FA filtration and breakthrough characteristics were improved with wet media except PAC and ACL. In particular, purification performance improvement and breakthrough mitigation were higher in pumice and loess ceramic balls. PAC+ZEO mixing showed the most high purification performance and breakthrough mitigation in all mixing methods. Thus mixture of PAC with zeolite and vertical mixing could be recommended as additional filter media to improve the FA purification ability and pressure drop with indoor air biofilter system.
