계절에 따른 정원의 경관 변화 특성을 알아보고자, 우수 정 원 4개소를 대상으로 계절별 식재 특성과 색채 변화를 분석하 였다. 대상 정원에서 계절별로 조사된 식재 종수 합은 346분 류군이었고, 교목:관목:초본의 식재 백분율(%)은 8:21:71로 나 타났다. 초본은 봄을 기준으로 여름과 가을에 각각 6%와 15% 증가하였다. 관목은 봄에서 가을까지 계절 변화에 따라 64-100% 증가하였다. 계절에 따라 정원의 포인트 식물이 달라 졌으나, 꽃이 만발하는 초본과 관목으로 나타났다. 색채 분석 결과, 정원의 주조색은 식물 생육이 왕성한 봄과 여름에는 녹 색에서 짙은 녹색으로 나타났고, 가을에는 갈색으로 확인되었 다. 강조색은 계절에 따라 분명하게 달라졌으며, 주로 계절별 특징적인 화색이나 잎무늬로 결정되었다.

우리나라 정원의 식물 이용 현황을 알아보고자 전국 36개 정원을 대상으로 정원식물을 조사하였다. 정원은 6가지 유형 으로 구분하였다. 그 결과, 36개소 정원에는 정원식물 712종 류가 식재되고 있었다. 교목, 관목, 초본의 비중은 평균 1:2:7 이었다. 개별 정원(10×10㎡)에서 교목은 평균 2.5종으로 12.6%, 관목은 4.1종 20.7%, 초본은 13.2종 66.7%를 차지했다. 식재 빈도 상위 5%에 40여 종이 포함되었으며, 맥문동, 일본조팝나 무, 수국, 회양목, 단풍나무, 옥잠화, 에키네시아, 산철쭉이 대 표적이었다. 양지형 정원에는 관목이 상대적으로 적고 초본이 많았으며 다른 유형보다 20~40% 이상 다양했다. 그늘형은 초 본보다 교목이 많았으며, 건조형 및 습지형과 마찬가지로 식 재 다양성이 20% 감소했다. 옥상정원의 도시형 정원은 초본 이 전체의 80~90%를 차지하고, 해안형 정원에는 목본과 초본 이 1:1로 목본 중심의 식재 특성을 보였다. 결과적으로 정원 유형에 따라 식재 다양성과 구성 비율이 명확한 차이를 나타 냈다.

원전 해체 공정 중 절단 및 용융작업에서 발생되는 방사성 에어로졸은 작업종사자의 호흡을 통해 내부 피폭을 유발하게 된다. 이에 따라 해체 중 방사성 에어로졸로 인한 작업종사자의 내부피폭 평가가 필요한 실정이다. 정확한 내부피폭평가를 위해서는 작업종사자의 작업환경 실측값이 필요하지만 실측에 어려움이 있을 시에는 국제방사선방호위원회(ICRP)에서 제시하는 섭취량 분율 및 입자 크기 등의 권고 값을 통해 내부피폭선량을 추정할 수 있다. 본 논문에서는 입자 크기의 선정은 ICRP에서 권고하는 작업종사자의 고려 입자 크기인 5 μm을 적용하였다. 발생량의 경우, 불가리아의 Kozloduy 부지 내의 용융시설에서 발생 된 에어로졸의 포집량 데이터를 이용하여 섭취량을 산정하였다. 또한 이를 이용해 작업종사자의 체내 및 배설물에서의 방사능 수치를 계산하고 BiDAS 전산코드를 통해 내부피폭 평가를 수행하였다. Type M이 0.0341 mSv, Type S가 0.0909 mSv로 두 흡수 형태 각각 국내 연간 선량 한도의 0.17%, 0.45% 수준을 나타내었다.

원전사고 및 시설보수 과정에서 방출되는 방사성물질 중 137Cs은 토양의 주 오염원 중 하나이다. 세슘으로 인한 토양오염은 주민의 거주 및 공업용지로의 재사용을 위해 제염이 불가피하다. 본 연구에서는 다양한 토양복원 기술 중 국내·외에서 실 제 방사성물질로 오염된 토양에 적용한 사례가 있는 토양세척 기술을 선정하였다. 토양세척 공정은 세척제를 사용하여 토양 과 세슘의 표면장력을 약화시켜 토양과 세슘을 분리하는 원리이다. 이러한 토양세척 공정의 세척수 재사용을 통해 공정효율 을 높이고자 세척수에 응집제를 적용하여 미세토양 및 세슘의 제거 성능 실험을 수행하였다. ICP-OES를 통해 세슘 수용액 에 토양을 첨가하여 세슘을 흡착시킨 후 응집제를 첨가하여 세슘의 농도를 측정하였으며 응집제 적용시 최대 세슘 제거율은 약 88%, 최소는 67%였다. Visual MINTEQ Code를 통한 세슘과 토양과의 종결합을 예측하였으며 탁도 측정을 통해 응집제 투여 후 탁도를 측정하여 세척수의 재사용 여부 및 미세토양 제거율을 분석하였다.

The present study aimed to figure out current situation and consumer perception on the advertising of functional climbing wear in Korea. Advertising is about showing consumers how products meet their needs. In case of functional clothing, the most basic need of consumer should be a functional need (Lee, 2014;Shimp, 2010). However, research on advertisement of functional clothing, especially focused on the functional information, has not carried out in Korea. Recently research by Liu and Yoo (2014) investigated changing patterns of magazine advertising of functional climbing wear from 2008 to 2013. It is found that advertisements of professional climbing wear had been changed like fashion apparel ads in terms of functional information, celebrity model dependence, and appeal type (Liu&Yoo,2014). On 2013, over 70% of functional climbing wear ads did not provide any functional information and percentage of celebrity model dependence was dramatically increased from 1.48%to35.30%. In this study, 388 adults in their 20-50’s were surveyed in order to figure out general satisfaction on advertisements of functional climbing wear. The survey consisted of eight questions including satisfaction with reliability, communicability, type of expression, model, and contents of functional climbing wear advertisement. For analysis of characteristics of respondents, years of climbing experience, frequency of climbing, average expenses per single purchase, and frequently exposed advertising media types were asked as well as demographic characteristics. Most of respondents (83.85%) were in their 30-50’s and had 3-5 years climbing experience (29.50%).Frequency of climbing was ‘once every two months’ (35.70%) and ‘1~2 times every month’ (25.26%), and the most frequent average expenses per single purchase was ‘100~300 thousand won’ (65.25%). Frequently exposed advertising media types were TV commercials (33.60%), magazine (23.10%), and internet (9.50%). Purchase frequency was ‘once every two tears’ (31.14%), ‘3~4 times in a year’ (29.11%), ‘1~2 times in a year’ (25.06%). Results showed respondents want ‘more precise information for better understanding of performance of functional climbing wears’ (4.22point out of 5.00). Significant differences in ‘advertisement of functional climbing wear is reliable’ were observed across age and gender; male rather than female group and ages 30 are than other age groups showed higher average value. Age 40’s significantly more wanted to be informed precise information via advertisement and preferred celebrity model than other age groups. Overall, ages 20-30’s were more satisfied with the advertisement of functional climbing wear than age 50’s. The results from this study could provide practical insights to establish guidelines for providing product information in the functional clothing industry.

Based on the research finding, the conclusions are as follows: 1. According to the result of questionnaire survey, at present the apron material that chef wear does not have fire retardant function, chef expect apron material can add this function, they think apron material adding this function can protect physiological health, proving the necessity for developing fire retardant apron. 2. This study use the result of chef’s need expectation, and combine ergonomics data to adjust existing apron structure design, then this study use fire retardant cloth to develop fire retardant apron to meet chef’s need expectation. 3. Through the sensibility evaluation test of fire retardant apron developed by this study, those who exposed to higher temperature fry stove fire, charcoal fire or caldron cook in specific kitchen infield for a long period of time have higher preference and feeling.

Padded outers (jackets, jumpers or coats) are a popular and “must have” item for cold weather because they provide light weight warmth and good style. This study investigates Korean female’ attitudes and factors on purchase decisions for luxury padding outers by level of involvement. A total of 287 female respondents participated in the survey with data obtained using a random sampling method from on and off line respondents aged20’sto40’sinthe Seoul and Gyeonggi area. The study was based on the Maslow’s Hierarchy of needs and Zaichkowsky’s concept. Respondents were asked to indicate their degree of agreement on a 5 point Likert scaled that measured involvement, attitudes, and decision purchased factors. Factor analysis, cluster analysis, correlation and T test were conducted. A factor analysis on 9 needs/motivation measures about padded outer products indicated two factors of a motivation factor and physiological factor for “expectations to have a more positive outcome”. Involvement related to 10 measures about padded outer products indicated two factors of “personality/desires” and “interest/value”. In addition, two other factors were extracted in attitude measure variables of “positive attitudes” and “negative attitudes” towards premium outers. We realized that “expectations to have a more positive outcome” motivation influenced positive attitudes more than “physiological” motivation about premium padded outers. “Personality” involvement factor correlated highly with “positive” attitude factor towards exclusive padded outers (Pearson r=0.766), while the “interest” involvement factor correlated slightly. We can interpret individuals are very positive towards premium products if someone has expectancy to achieve desirable outcomes and wants to express personality. Clustering from involvement measures based on needs, values and interests were classified into two groups. There was a significant difference in the respondents’ purchase decision factors between two segments based on the levels of involvement (p<0.001). The high product involvement group was brand and country of origin conscious, material conscious, trend sensitive, luxury image seeking, and less padding outer price conscious. The low product involvement group was more color conscious in purchases. The findings imply that different marketing approaches are recommended to target each segment in the outer clothing markets.

This study enhances the capability to reproduce multi-coloured images in woven Jacquard forms where weave structure and pattern design were considerably involved in fabrication. In modern weaving, great convenience and efficiencies were established in both production and design process through digitalisation, while the colour adoption has been constrained as the applicable number of figuring yarns were limited. The enhancement toward colour realisation is traditionally related to weaving capability. Surface colour display is dominated by additive, subtractive or optical mixing (Mathur, 2007). An additive colour system offers the largest gamut among output models yet, the light mixing principle is not suitable to apply to weave colour creation. Pre-dyed opaque yarns are used and juxtaposed; small particles of yarn colours reflect lights and they were observed as a certain form of colour. The common and crucial criterial pertinent to an optical mixing of weave colours were aligned more with the subtractive mixing principle. A weave pattern was designed by subtractive primary colour classification and a multi-weft figuring method. Secondary colours are theoretically produced when coupled CMY layers are mixed(i.e., cyan + magenta = blue, cyan + yellow = green, magenta + yellow = red) and black is generated when all CMY primaries are mixed (Berns, 2000);however, non-bendable colours of threads are employed for colour reproduction in weaving and there is a limit to adopt a pigment mixing principle in the woven form. Therefore, each weave pattern required a modification to redefine primary colour regions and densities once an original artwork was separated and presented in greyscales levels. The weave patterns in an original subtractive scheme were altered by applying region-based segmentation to maximise the accessible colour gamut. In this study, the weaving application developed for the multi-coloured image was introduced and the design process was explained based on a practical experiment proceeded with a newly developed weaving application.

Temperature and insecticide are two important factors that affect survival, reproduction and other physiological processes of insects. To determine interactions of temperature and insecticide treatment on susceptible (S) and imidacloprid-resistant strains (IMI-R) of Aphis gossypii, adults were exposed to three temperatures (17, 22, and 28℃) or combinations of three temperatures (17, 22 and 28℃) and imidacloprid (LC20), and the expression of several genes (heat shock protein 70, cuticle protein, cytochrome P450, and elongation factor) were analyzed. The expression level at 17℃ of heat shock protein 70, cuticle protein, and elongation factor in S strain were up-regulated with increased time and higher than those of IMI-R strain. However, expression of cytochrome P450 was not affected by elevated temperature both S and IMI-R strain. Combined treatment of elevated temperature and imidacloprid were significantly up-regulated only cuticle protein in S strain and higher than those of IMI-R strain.

This study was conducted to investigate the anti-bacterial effect of chlorine dioxide (ClO2) on extending thevase life of Gerbera jamesonii ‘Jenny’ which was first bredin Korea in 2012. Compared to commercialized biocides,ClO2 had been proved significantly effective for extendingthe vase life of cut gerbera flowers, equally with sodiumhypochlorite, silver nitrate, and 8-hydroxyquinoline sulfate.No bacteria were detected in the vase solutions treated withClO2 and these commercialized biocides on day 6 aftertreatment. But there were no significant differences on thevase life among the three ClO2 concentrations: 2, 5, and10μL•L−1. The ClO2 concentrations were rapidly decreasedon day 2 after treatment regardless of peduncle existence.Nevertheless, the antibacterial effect of ClO2 was main-tained up to day 6, indicating that the initial antibacterialeffect of ClO2 was a key factor for extending the vase life inthe gerbera flowers. The study results verified the antibacte-rial effect of ClO2 on prolonging the vase life of Gerberajamesonii ‘Jenny’ and demonstrated that appropriate ClO2application can prolong the postharvest life of cut gerberasvia its antimicrobial effect.

This study was performed to evaluate antimicrobial resistance of food-borne pathogens isolated from retail meat in Korea. A total of 157 samples of beef, pork, and chicken were collected and analyzed for E. coli, Salmonella, Campylobacter. Resistances to tetracycline were declined in accord with reduced usage of tetracycline in live stock production. E. coli stains from chicken meat had higher multi-drug resistance ratio than strains from other meat. One extended spectrum beta lactamase (ESBL) producing E. coli and two ESBL producing Salmonella were identified in this study. ESBL producing Salmonella strains were confirmed to carry CTX-M-1 type genes.

Lung cancer caused by diverse changes in cells resulted by exposure to carcinogens found in tobacco smoke, the environment, or sequential accumulation of genetic changes to the normal epithelial cells of the lung. An assessment was made of the anti-proliferative activity of constituents from silkworm feces against 11 human cancer cell lines, including A549 and H727 lung cancer cell lines, using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay. The ethanol extract of silkworm feces was proved to have anti-proliferative activity against all 11 species of human cancer cell lines. The biologically active constituent was characterized as vomifoliol (blumenol A) (1) and stigmasterol (2) by spectroscopic analysis ,including MS and NMR. In conclusion, global efforts to reduce the level of antitcancer agents justify further studies on the silkworm feces-derived materials containing vomifoliol and stigmasterol as potential anticancer products or lead compounds for the prevention or eradication from human lung cancer.

In the previous study, the plant essential oils such as clove bud , thyme white and garlic oils gave potent toxicity with the range of 1.5 to 4.5×10-3 ul cm-3 of LC50 values against Bemisia tabaci. Based on the bio-assay results, three plant essential oils(clove bud, thyme white and garlic) were applied to 30% emulsion type. The 100, 200 and 400 fold dilution of these emulsions was showed mild toxicity under port scale treatment against Q biotype. At each fold dilution, clove bud showed 44, 26 and 14%, and thyme white produced 44, 39 and 27%, respectively. Of garlic emulsion, its toxicity was evaluated with 27, 26 and 11%, respectively. But, in case of clove bud and thyme white mixture, their toxicity was more good under the mixture than under the single treatment. Mixture with clove bud 200 fold dilution adding to thyme white 200 fold dilution showed potent activity with 86% mortality. And also 200 adding to 400, and 400 to 400 exhibited 61%, 76%, respectively. These essential oil mixtures showed similar strong toxicity against B biotype under port scale test. In particular, the mixture with clove bud 200 fold dilution adding to thyme white 200 fold dilution showed the highest synergistic effect. Toxicity to plants, except the 100 fold dilution of these emulsions was not observed.
