The skin is an organ that covers the outside of the human body. And it regulates body temperature, performs sensory function, deliveries the drug, and represents the abnormality of the internal organs. For these reasons, people have been expressing the condition of the body based on the state of the skin of the face to detect sign of health, "you look well", "face with vitality". Depending on the degree of aging and the environment, it is a fact that skin color, skin texture, moisture and firmness could be different. In particular, the color of the skin acts as a factor that affects to determine the subjective impression such as beauty and charm. We could expect consumer's demand through the market of whitening cosmetics and skin treatment. However, existing most of the cosmetics focus on improving whiteness. The number of studies that focused on skin color is not enough. In this study, we found out the skin color condition by carrying out surveys of 100 women between 30s and 40s. Our study would be very useful to develop new cosmetic products and to satisfy customer's needs.

This study aimed to research theoretical reviews of streetscape and to analysis the correlation between visual properties and preference of streetscape in Bukchon around Gahoe-dong which is a dense Hanok area. Therefore we analyzed a relation between visual quantities and preference intended Samcheong-dong 35 street, Gahoe-dong 31 street and Gahoe-dong 11 street the representative streetscape in Bukchon. Also we extracted common factors of images of the streetscape in Bukchon and figured out a relation between the visual image evaluation and the preference by regression analysis. The result of the analysis is as follows. First, it was the streetscape of Gahoe-dong 31 street which get more scores than any other streetscape in preference. And we figured out that the higher the ceiling and the visual quantities of planting the more preference. Second, streetscape in Bukchon was explained by 'aesthetics', 'amenity' and 'orderliness' in psychological view. And there was noticeable difference in aesthetics aspect between Gahoe-dong 31 street the highest preferred place and the Samcheong-dong 35 street the lowest preferred place. Third, as a result of regression analysis on preference and factor scores about psychological variables, we figured out that the factor which explains aesthetics effects most on the preference.

밀도는 플라즈마의 기본적인 물리적 성질을 이해하는데 중요한 인자로 인식되고 있으며 많은 방법들이 밀도분포의 측정에 이용되었다. 이 중 마이크로파 진단법의 하나인 레플렉토메터리는 그 고유한 특성 때문에 현재 밀도분포측정법으로써 폭넓게 활용되고 있다. 그러나 레플렉토메터리 신호에 대한 처리 및 분석 방법은 다양하여 주어진 플라즈마에 가장 절적한 방법을 선택하는 것은 쉽지 않다. 본 논문에서는 레플렉토메터리의 신호로부터 밀도분포를 정확히 재구성하는 알고리즘을 개발하기 위한 기초 단계로써 모의된 레플렉토메터리 선호에 기존의 신호해석법들 중 우수한 해석법으로 알려진 CDM(complex demodulation method)과 웨이브레트(wavelet) 분석법을 적용하여 밀도분포재구성에 대한 양자의 성능을 비교한다. 그리고 플라즈마의 특성에 기초하여 모의된 신호에 실제 상황에서 존재할 수 있는 잡음신호를 첨가하여 이것이 밀도분포 재구성에 미치는 효과를 조사한다.

This study aims to suggest improved design for both non-smokers and smokers to minimize inconvenience of smoke, at the same time, allow smoking in comfortable environment. The study was researched in three categories: First, consciousness research regarding smoking booth, second, preference research regarding product design, and third, research on emotional words about smoking booth by emotion evaluation. The result of design preference research was, first of all, smoking booth for smokers should be designed in both notable and familiar shape rather than stiff and rough shape. Second, color for the booth should apply warm colors such as white, pastel, and bright tone rather than prime colors. Third, the internal circulation filter in smoking booth should be managed thoroughly. In addition, extra seats and ventilation design is necessary to prevent passive smoking. The result of emotion evaluation was that people recognized certain words in four aspects. Each image word for factor 1 was "functional emotion', factor 2 was "psychological emotion", factor 3 as "color emotion", and factor 4 as "shape emotion". User-centered service design is necessary for both smokers and non-smokers, to minimize the damage by smoke and to spend time for short break.

Improving quality is a very important component of maintaining competitiveness of agricultural products. However, evaluation of 'high quality' indicates it is a very abstract concept and independent of some quality attributes, leading to differences in the perception of quality. Thus, there is a pressing need to objectively define 'high quality' and to develop basic technologies for its measurement, for application in the production, storage and distribution of competitive agricultural products. To objectively quantify apple quality, a survey was conducted on consumer preferences and awareness of quality attributes including color, taste, flavor and shape. The survey questionnaire targeted male and female adults (463 persons) ranging in age from 20 to 59 years. The questionnaire was based on purchases made at a wholesale market (50.1%) or a traditional market (18.8%). The majority of purchases were as small packets (62.0%) or as individual pieces (20.5%). Apples of moderate size (fist size, 60.5%) were preferred over small (4.3%) or large (32.6%) apples. The questionnaire provided consumer data on external quality attributes including color, shape and variety. Taste attributes were evaluated in relation to the balance between sour and sweet taste, and flavors peculiar to apples.

This study analyzed the preference depending on street planting types and visual characteristics on Dongdaegu-ro located in Suseong-gu, Daegu Metropolitan City. The Single Row Roadside, Central Sidewalk Plantings, Double Row Parallel and Alternate Plantings were selected as the planting types. The plantings were divided at intervals of 4, 7 and 10 meters. A survey was conducted by dynamic simulation produced from pedestrian perspective. As a result, in single planting, the single central sidewalk planting with 4 meter-interval showed a high landscape preference 4.64. In addition, in double planting, the double alternate planting with 7 meter-interval showed the highest landscape preference 5.01. The factors that had the greatest effect on the landscape preference were 'comfortable' and 'beautiful'. It was considered that they should be preferentially taken into account in producing landscapes by planting. It was considered that they should be preferentially taken into account. It is also considered that this study will be used for objective data and planting plan for establishing the comfortable and high quality streetscape by quantitative evaluation of the visual characteristics and preference according to the street planting types.

To obtain the basic data for the conservation and cultivation of native herb species under the forest, the relations between distribution of native herb species and site factors, distribution of native herb species, and site factors were surveyed on natural forest at subalpine zone in Mt. Odae. Ainsliaea acerifolia, Pseudostellaria palibiniana and Pimpinedla brachycarpa were distributed mainly on broadleaved mixed forest, Clematis fusca var. coreana, Carex siderosticta. Isodon excisus and Vicia unijuga did mainly on gab sites. The distribution of Ligularia fisheri, Aconitum pseudo-laeve var. erectum, Cacalia hastata and Artemisia stolonifera were significantly differed between slope directions. Artemisia stolonifera was distributed more frequently in south directed slope, and Ligularia fisheri, Aconitum pseudo-laeve var. erectum and Cacalia hastata were distributed more frequently in north and west directed slope than the other. The distribution of Aconitum pseudo-laeve var. erectum and Artemisia stolonifera were significantly differed between soil moisture conditions. Artemisia stolonifera was distributed mainly on the dry site, but Aconitum pseudo-laeve var. erectum did mainly on the dry site. Negative correlations between density of Clematis fusca var. coreana, Carex siderosticta. Isodon excises and Vicia unijuga and crown coverage was proved. Aconitum pseudo-laeve var. erectum, Pimpinella brachycarpa, Meehania urticifolia, Smilacina japonica and Pseudostellaria palibiniana were mainly distributed on wet and shady sites under forest canopy, but Pedicularis resupinata, Clematis fusca var. coreana and Artemisia stolonifera did on sunny sites at forest edge or gab.
