Consumer perception of the meaning of 'green' and 'green products' as well as how they use green claims (including terms, certifications, and marks) should be examined to help consumers pursue green behavior in everyday life. This study investigates what type of green claims prevail in the Korean consumer market and how consumers perceive the meaning of 'green' and green claims. For these purposes, media analysis, in-context research (shop visit) and a survey were conducted to collect green claims (including green terms and certified/noncertified green marks). Green claims in the consumer market were first summarized and analyzed; subsequently, the most frequently used 7 green marks and 15 green terms were selected to construct a consumer survey questionnaire on consumer perceptions of green claims. An online survey was performed via Embrain and the survey respondents consisted of 500 adult consumers over the age of 20. The field research results showed frequent green claims in the Korean consumer market. However, certified (and hence trustworthy green product information labels) were uncommon in the market. The only green claim widely known and used by consumers was the energy consumption efficiency label. Consumers were interested in the green information label not because it affected their utility cost nor because it was important for environment protection.

본 시험은 미국과 유럽으로부터 도입된 5개 초종 23개 품종의 한지형 잔디의 생육특성, 추위와 가뭄에 대한 내성, 내병성 및 녹색도를 조사하기 위하여 1995년 연암축산원예전문대학 잔디시험 포장에서 실시하였다. Kentucky bluegrass는 8개 품종중에 Newport 와 Glade가 우수하였는데 Newport는 균일성, 피복도, 질감 등에서 최고의 품질을 나타내었으며 여름철의 질병에도 강하였으나 녹색도가 옅고 가뭄에 대한 저항성, 가을철의 녹병에는 약하였고 늦가을의 녹색도가 유지되지 않는 단점이 있었으며 Glade 품종은 녹색도가 진하며 밀도, 피복도, 균일성, 여름철 질병과 녹병에 대한 저항성 등에서 모두 중상정도로 우수하였으나 가뭄에 대한 저항성과 질감이 다소 나쁘고 Pythium blight에 약하였다. Tall fescue는 5개 품종 중 Revel과 Revel Jr. 품종이 진한 녹색을 나타내었으며 밀도, 균일성, 피복도 등 거의 모든 조사항목에서 다른 품종에 비해 우수한 결과를 나타내었다. Red fescue는 봄철의 질감은 뛰어났지만 모든 품종이 여름장마철에 질병으로 사멸하였다. Ryegrass는 4개 품종중 Dandy 품종이 질감을 제외한 거의 모든 조사항목에서 다른 품종에 비해 매우 우수한 결과를 나타내었다.

This study looked at worked on remaining landscapes in terms of landscape ecology. It presented some ways to conserve and to activate remaining landscapes with examples of agricultural lands in Hwa-won Gun, Ok-po Myun. The results are as follows: We investigated 20 remaining landscape types and 90 remaining landscapes, and classified them in terms of forest and water zones. To evaluate the investigated remaining landscapes, we produced a grading system using 8 criteria such as vitality, stability, field suitability, type of inner scenery formation, connection, recreation, and culture/tradition. Our evaluation of the vitality found that Grade I had the mast remaining landscapes; Grade II had 28, Grade III had 16, Grade V had four, and Grade IV had none. We evaluated the outer landscape influence using 3 criteria such as divisibility, vitality, and indication. We found from evaluating the type of inner scenery formation that most of the landscapes superior to Grade III were adjacent to water zones and that linear landscapes evaluated as Grade I, and II played an important role in this connection. We evaluated the recreation probability using marks, frequencies, and emergencies of peculiar types. Based on the results, we proposed some ways to conserve and to activate the remaining landscapes classified by grades using the results of the last evaluation. Additionally, we proposed some ways to activate the restoration of the linear axis of the green space function the formation of a buffer green space around matric space, the improvement of the axis of the green space center, and the formation of additional green tracts of land to play the role of stepping stones. We proposed the possibility of improving uniformed farm land structures. This study did not consider the weighting values of the evaluation index. Therefore a more objective study will be needed with an expert-survey in the future.

본 논문은 RFC2963에서 제안된 single rate Rate adaptive Shaper (srRAS)를 설계한 것이다. srRAS는 RFC2693에서 제안된 하향의 single rate Three Color Marker (srTCM)과 함께 사용된 쉐이퍼이다. 그것은 가변 속도로 출력되는 tail-drop FIFO (First Input First Out) 큐이다. srTCM은 srRAS로부터의 IP 패킷 스트림을 측정한 후 그 패킷을 green, yellow, 또는 red로 마킹해 준다. 이 쉐이퍼는 AF PHB (Per Hop Behavior)를 제공하는 DS (Differentiated Service) 네트워크의 입력에서 사용되도록 제안되었다. 그리고 srRAS는 srTCM의 상향 트래픽의 버스트성을 줄여줄 수 있다. 본 논문은 srRAS의 알고리즘, 구조, 그리고 FPGA 및 관련 기술을 통하여 구현할 수 있는 방안을 언급하였다.

본 논문은 DiffServ 방식에서 Assured Service를 이용하는 각 사용자 플로간에 수율의 공평성을 향상시키기 위하여 도메인 입구 라우터에서 Aggregate Fairness Marker (AFM)를 제안한다. 각 사용자별 플로의 패킷 표기 방법은 본 논문에서 제안하는 방법인 user flow Three Color Marker (uf-TCM)에 따라서 각각 green 패킷과 yellow 패킷, 그리고 red 패킷으로 구분되어 나온다. yellow 패킷은 uf-TCM에서 손실된 토큰을 소비하는 패킷 및 AFM에서 집합 트래픽에 대한 계약률을 준수하지 못하여 demotion 된 green 패킷에 대한 표기 방법이다. 제안하는 AFM은 플로별 관리 없이 공평한 방법으로 yellow 패킷을 green 패킷으로 promotion 하거나 green 패킷을 yellow 패킷으로 demotion 하여 사용자별 수율의 공평성 및 링크 이용률을 향상시킨다. DiffServ 내부 라우터에서는 yellow 패킷과 red패킷의 패킷 폐기 우선순위를 동일하게 하여 RIO 버퍼 관리 방식을 사용할 수 있게 한다. 성능 평가는 제안하는 AFM과 플로별 관리 없이 수율 공평성 향상을 위해 제안되었던 REDP Marker를 비교하였으며, 시뮬레이션 결과는 본 논문에서 제안하는 방식이 잉여 대역폭이 있는 경우와 최소대역폭이 있는 경우, 그리고 대역폭이 부족한 상황에서 각 사용자 플로간의 수율 공평성 및 링크 이용률 향상에 효과가 있음을 단일 도메인뿐만 아니라 다중 도메인 환경에서도 보인다.

This study was conducted to examine morphological characteristics and the content of cell wall polysaccharides of Brassica campestris var. pekinensis(baechu). First of all, the variety of scientific name and naming of parts of baechu in the literatures of kimchi showed, which will unify marks. So, we propose not so much mid-rib and leaf blade of baechu leaf as white part and green part, respectively. On the other hand, the forms of vessel elements of white part in baechu consist in ring, sclariform and reticulate thickening. The proximate compositions and contents of cell wall polysaccharides of baechu has significant differences between its cultivars. The cell wall pectin from baechu exhibited four peals with molecular weights of 2,000,000, about 100,000 and less than 10,000 by gel filteration chromatography and hemicellulose did two peaks with molecular weights of 2,000,000 and 10,000.

Optically transparent and flexible electronic circuits and displays are attractive for next-generation visual technologies, including windshield displays, head-mounted displays, and transparent screen monitors. Here we report on the fabrication of transparent transistors and circuits based on the combination of nanoscopic dielectrics and organic, inorganic, or hybrid semiconductors. Furthermore, the first demonstration of a transparent and flexible AMOLED display driven solely by $In_2O_3$ nanowire transistors (NWTs) is reported. The display region exhibits an optical transmittance of ~35% and a green peak luminance of ${\sim}300\;cd/m^2$. These results indicate that NWT-based drive circuits are attractive for fully transparent display technologies.

This study was carried out to investigate the effect of grain and veneer thickness on drying rate, required energy consumption, and drying defects such as checking, end waving, and burning during a far-infrared radiation drying process of decorative veneers of hard maple and beech. Most of the veneer could be dried from green to in-use moisture content within 30 to 360 seconds. The drying rates were significantly affected by veneer thickness, but there was little difference between edge-and flat-sliced veneers. The formation of checking during drying test was none or very slight. The percentages of the veneers defected by checks were higher in the flat-sliced veneers than in the edge-sliced veneers. The maximum end wavinesses in the flat-sliced veneers were almost 1.6 to 3 times larger than that in the edge-sliced veneers. All veneers were fee from burned marks during drying test.

Objectives : Southern, northern, and wild types of Osterici Radix, and Notopterigii Rhizoma et Radix imported from China are circulated in Korea. Morphological identification was attempted by comparing external and internal forms of these materials. Methods : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT. Results : 1. Southern type of Osterici Radix has short rhizome and many small and long roots, while northern type of it is mostly composed of rhizomes with little small reds and sometimes looks like bamboo because of the extention of the parts between joints. 2. Parenchymal cell of southern type of Osterici Radix is filled with starch grain, while that of nothern type includes less starch grain with lamination crossed on its cell wall. 3. Surface of root and rhizome of wild Osterici Radix has some marks of fibrous root raised in the form of nodule, but cultivated Osterici Radix does not have this kind of marks. 4. Notopterigii Rhizoma et Radix is mostly composed of rhizomes, and its form is similar to that of a silkworm or joints of bamboo. Parenchymal cell is filled with starch grains, and lamination is crossed on its cell wall but not salient. Conclusion : Southern, northern, and wild types of Osterici Radix, and Notopterigii Rhizoma et Radix circulated in Korea can be easily identified because of their differences in their external and internal forms.
