This study was carried out in order to analyze a repletion possibility about color change of base paper after elevated heat exposure when wooden fillers were added. Fillers may reduce production cost because its price is usually inexpensive than pulp with higher bulkiness. Wooden fillers have lower density than inorganic fillers, so they may increase bulk more than inorganic fillers. Never the less wooden fillers have disadvantage of yellow color by heat exposure, so the addition level should be carefully controlled. Brightness and whiteness changes after elevated heat exposure depending on coating weight were analyzed. With wooden fillers addition, breaking length and surface strength decreased but bulkiness increased. As the exposure time of elevated heat increased the coating paper with wooden fillers addition had higher brightness and whiteness values than those of inorganic fillers.

제품의 LIFE CYCLE이 짧아지고 있는 추세에 이미 출시된 제품에서 칼라 변경만을 통해 신제품과 같은 효과를 볼 수 있는데 칼라변경은 기능추가나 금형 수정에 비해 상대적으로 비용이 적게 들어가기 때문에 그 효용성은 더욱 크다고 할 수 있다. 본 연구는 현재 판매되고 있는 A사의 가습기를 Trend 분석을 통해 칼라와 그래픽 요소의 변경만으로 신 제품화하여 가습기 칼라 변경에 대한 경쟁력을 높이기 위한 디자인 사례연구이다.

For waste recyle, we were investigated on Gardenia blue color production using Gardenia by-product by Bacillus subtilits. Optimum conditions for producing blue pigment were found to be 30$^{\circ}C$, initial pH 6.5, glucose as a carbon source 3% and yeast extract as a nitrogen source 0.5%, respectively. Optimum conditions for fermentor culture were agitation speed 400rpm, aeration 2 vvm and inoculum 5%. The optimum perculture time for inoculum was 20 hrs for blue pigment production.

The purpose of this study is to investigate the content and changes of modern Korean men's wear advertisement from the 1960s to the 1990s by reviewing fashion magazines and pictorials. Research problems were as follows.; First, analyze the types and their units of measurement in men's fashion advertisements from 1962 to 1998. Second, examine the differences of quantitative change in men's fashion advertisements according to each period. The total 857 advertisements were selected from Shin Dong-A, Joongang Magazine, and Bokjangwolbo from 1972 to 1998. For analyze the result, frequency analysis and $x^2$-test were used. Results were as follows. First, through the review of literatures and pre-tests, 6 units of measurement were identified. They were product type(formal wear, casual wear, sports wear, dress shirts, accessory, inner wear, fabric and the others), brand type(national brand, licensed brand, imported brand, others), appeal type(image, product, others), representation type(photograph, illustration, others), medium type(man, product, others), and color type of advertisement(black & white picture, color picture). Second, for the types of advertisements, formal wear, national brand, image appeal, figure medium, photograph for presentation and color picture are the most frequently shown in men's fashion advertisements from 1962 to 1998. Third, for product, more accessory advertisements were found than the clothing in the 60s and the 70s, and casual wear advertisements in the 80s and formal wear advertisements in the 90s were dominated. National brand type was dominant through all four period. Product appeal type in the 60s and the 70s and image appeal type in the 80s and the 90s were prevailed. For medium, product type in the 60s and the 70s and figure type in the 80s and the 90s were dominated. Black & white picture in the 60s and the 70s and color picture in the 80s and the 90s were prevailed. Lastly, photograph was the most frequently used for presentation type through all periods.

Ocean Color product들은 해양 생태계를 이해하기 위해 중요한 변수이다. 고위도 지역에서는 해빙이 바다로 유입되어 ocean color product에 광학적인 영향을 미친다. 본 연구에서는 북극 다산기지 근해의 피요르드에 대한 광학적 특성을 평가하고 높은 공간해상도를 가진 Landsat-8 OLI 영상의 엽록소-a(chlorophyll-a)와 부유물질(suspended sediment) 농도를 산출하고자 한다. 엽록소-a와 부유물질 농도를 추정하기 위해서 band ratio를 이용한 다양한 회귀 모델을 테스트했다. 위성영상과 관측된 실측 값과의 시간적인 차이 때문에 사용된 회귀모델은 높은 상관관계를 가지지는 못하였다. 하지만 Landsat-8 OLI 영상을 이용한 모델에서 생산된 엽록소-a와 부유물질 농도는 북극해 주변 피요르드와 해안지역에 대한 고해상도 위성 데이터를 활용한 모니터링 가능성을 보여주었다. 북극해 주변의 기후변화 패턴을 이해하기 위해서는 해양 생태계 변화에 ice meltig이 어떠한 영향을 미치는지를 이해하는 것이 필요하다. 본 연구의 결과는 고위도지역에서 ice melting이 해양생태계 변화에 미치는 영향을 고해상도로 모니터링을 하는데 사용된다. 극지연구소는 2002년부터 스발바드 다산기지을 운영하고 있으며 한국의 북극 기지를 기반으로 연구를 수행하였다.

This study investigates the changes inconsumer sensibility and product preferences according to theirecofriendly productperceptions. Stimulants (released by three companies of sport casual brands)include three shirts made of recycled polyester and three made of organic cotton. A surveymethod was used to respond to the emotion and image while watching the presented pictures of the clothes. The change in the reactions was analyzed before and after the presentation of eco-friendliness information. The questionnaire consists of sensibility adjectives, open-ended questions about the associated image of eco-friendliness, color attractiveness, product favorability, price satisfaction, and reasons for an eco-friendly productpurchase. The survey was conducted on 200adult male and female participants. Two factors ('eco' and 'design')were identifiedthrough the factor analysis of image adjectives. There was a statistically significant increase in the evaluation of sensibility, color attractiveness, product favorability, and price satisfactiondue to the re-evaluation of the same products after consumers recognized the eco-friendly information of apparel products. When consumers recognize products aseco-friendly, they evaluate the products more positively than before. The result of the analysis of the increases by textile materials shows no significant difference in the sensibility changes depending on the materials. However, with regard to 'eco', the increase of sensibility change for organic cotton products was larger than for recycled polyester products.

Samples of banana were dried in a two-stage heat pump dryer capable of producing stepwise control of the inlet drying air temperature while keeping absolute humidity constant. Two stepwise air temperature profiles were tested. The incremental temperature step change in temperature of the drying air about the mean air temperature of 30 $^{\circ}C$ was 5 $^{\circ}C$. The total drying time for each temperature-time profile was about 300 minutes. The drying kinetics and color change of the products dried under these stepwise variation of the inlet air temperature were measured and compared with constant air temperature drying. The stepwise air temperature variation was found to yield better quality product in terms of color of the dried product. Further, it was found that by employing a step-down temperature profile, it was possible to reduce the drying time to reach the desired moisture content.

The number of children wearing make-up is increasing. "Children's cosmetics" is not a legal term though it is commonly used. The purpose of this study is to analyze discussions on children's cosmetics based on news articles found on the internet. This study also identifies what products are being distributed as children's cosmetics. Keyword searches were conducted using internet portal sites. Information was extracted from news articles and Best Item 100 for children's cosmetics. The results of analyzing news articles and Best Item 100 lists are as follows : 1. There were two main discussion topics in news articles. The first topic was related to marketing(the branding and trends of children's cosmetics). The other topic was about government regulations(side effects, harmful ingredients, control, regulations, attention, proper product usage, product categorization, and the overall safety of children's cosmetics). By 2014, many articles had covered government control and regulation. However, since 2017, news articles have focused on the product categorization and the concern for overall safety has dramatically increased. 2. Three different product categories have appeared in the Best Item 100; they are cosmetics, toys, and other products. In market, consumers recognized children's cosmetics as cosmetics and also as toys. Between 2017 and 2018's Best Item, other products are dramatically down, color cosmetics and single cosmetics are on the rise, and the purchase of domestic products has increased.

중합인산염 종류(STP, TSPP, SAPP 및 SHMP)와 염통의 첨가가 재구성돈육 제품의 물리화학적 성질에 미치는 영향을 조사하였다. 인산염 종류간에 TBA가나 보수력에 대한 효과는 차이가 없었으나, 조리손실을 줄여주는 효과는 STP와 TSPP가 다른 인산염에 비해 높았다. 소염통을 수준별( 5%, 10% 및 15%)로 첨가한 제품과 쇠고기를 비교하여 관능검사를 한 결과, 염통첨가 수준에 관계없이 재구성돈육의 조직과 색깔이 쇠고기와유사하게 나타났고, 다즙성이나 조리감량에서는 쇠고기보다 우수한 것으로 나타났다. 소염통을 돼지 염통으로 대체하였을 때의 효과는, 염통수준별 5%. 7.5% 및 10%)조리 감량 및 지방산화도에서는 크게 차이가 없었고 육색과 다즙성은 7.5% 및 10%첨가구가 5% 첨가구보다 유의하게 개선되었다. 육색 개선도를 기계적으로 측정한 결과, 염통첨가수준에 의한 영향은 redness의 증가에 의한 효과가 주된 것으로 나타났다.
