본 연구는 조경수용 무궁화 우수품종 보급을 위한 유전자원 수집과 특성을 평가하기 위해 최근 국내외에서 육성된 127품종의 1년생 접목묘를 이용하여 2014년부터 2015년까지 2년 동안 생육 및 형태적 특성조사를 실시하였다. 수집된 품종 중 화색 및 꽃이특이한 품종을 조사하여 무궁화를 조경수로 활용도를 높이는데 기여하고자 하였으며 얻어진 결과는 다음과 같다. 최근 국내외에서 육성된 품종들의 화색별 분류로는 크게 분홍색 단심(pink color with red eye spot), 흰색 단심(white color withred eye spot), 붉은 자주색 단심(purplish red color with red eye spot), 분홍보라색 단심(violet pink color with red eye spot), 심홍색단심(crimson color with red eye spot), 흰색 바탕에 붉은색 무늬의 이중색(asadal), 흰색(white color), 푸른색(blue color) 등 총 8종류로 분류되었다. 화색이 붉은 자주색으로서 적색이 강한 꽃으로 국내에서 육성된 품종으로 ‘광명’, ‘난파’, ‘노스페이스’, ‘불새’, ‘비단’,‘송암’, ‘영창’, ‘적퍼소’, ‘키호’, ‘탐라’, ‘화수레드’, ‘환희’ 등이 있었으며, 국외에서 육성되어 국내에 도입된 품종으로는 ‘Aphrodite’,‘Dr. Uemoto’, ‘Freedom’, ‘Pink Cup’, ‘PS 80-1’, ‘Purpureus Variegatus’, ‘Red Giant’, ‘Woodbridge’ 등이 있었다. 화색이 분홍보라색으로서 특이한 품종으로는 ‘꼬마’, ‘도투락’, ‘명미’, ‘병화’, ‘산처녀’, ‘태화’, ‘Hikari-hanagasa’, ‘Little Kim Violet’ 등이 있었다. 화색이 심홍색으로 기존의 꽃에서는 볼 수 없는 특이한 품종으로 ‘종무’와 ‘Ruffled Satin’ 등이 있었다. 최근 국내외에서 육성된 품종중 조경수용 소재로 보급할 수 있는 품종중 기존 품종에 비해 꽃의 크기가 큰 품종으로 무궁화 종간교잡종인 Hibiscus hybrid ‘Daewangchun’, ‘Daeil’,‘Jina’ 등이 있었다. 반면 꽃이 작고 조경적 가치가 높은 품종으로 ‘꼬마’, ‘미백’, ‘안동’, ‘릴킴’, ‘은하수’ 등이 있었다. 백단심계 무궁화‘꼬마’ 품종은 수고가 작은 왜성형으로 꽃의 크기가 5.2cm로 작은 소형화 품종으로 나타났다. 기존 품종에 비해 단심의 길이가 긴품종으로 ‘훈장’과 ‘하이리레드’가 있었다. 홍단심계 무궁화 ‘훈장’은 꽃의 크기는 12.0cm로 중간크기이나 단심길이는 4.8cm로 지금까지육성된 품종중 가장 긴 품종이었다. 또한 홍단심계 무궁화 ‘하이리레드’의 단심길이 역시 4.2cm로 꽃잎 길이에 비해 단심의 길이가 길어 조경적 가치가 높은 것으로 판단되었다. This study was carried out to characterize 127 recently developed cultivars of Rose of Sharon (Hibiscus spp.) in Korea and foreign Countries for landscape uses. The examined factors were growth characteristics such as tree height of a 1-year grafted plant(cm), plant type, growth habit, leaf characteristics such as shape and size, flower characteristics such as color, shape, size, and red eye during 2014 and 2015 for landscape uses. The results are obtained as follows; In the results of flower color of the 127 recently developed cultivars, pink color with red eye spot, white color with red eye spot, purplish red color with red eye spot, violet purple color with red eye spot, crimson color with red eye spot, asadal, blue color with red eye spot, and white color were distributed. In the flower characteristics, Hibiscus hybrid ‘Daewangchun’ had the largest flower size of 16.0cm out of the 127 cultivars. H. syriacus ‘Antong’, ‘Lil Kim’, and ‘Ggoma’ were cultivars with smaller flowers than other cultivars. H. syriacus ‘Hunjang’ had largest red eye, of 5.2cm of length compared to the other cultivars. The cultivars with unique flower color for landscape uses are H. syriacus ‘Kwangmyung’, ‘Nanpa’, ‘North face’, ‘Bulsae’, ‘Bidan’, ‘Songam’, ‘Youngchang’, ‘Jukpeoso’, ‘Kiho’, ‘Tamla’, ‘Hwasoored’ and ‘Hwanhee’. These flowers had a purplish red color and were developed in Korea. H. syriacus ‘Aphrodite’, ‘Dr. Uemoto’, ‘Freedom’, ‘Pink Cup’, ‘PS 80-1’, ‘Purpureus Variegatus’, ‘Red Giant’, ‘Woodbridge’ also had unique flowers with a purplish red color and were introduced from foreign countries. In addition, cultivars with violet pink flowers were H. syriacus ‘Ggoma’, ‘Doturak’, ‘Myungmi’, ‘Byunghwa’, ‘Sancheonyu’, ‘Taehwa’, ‘Hikari-hanagasa’, and ‘Little Kim Violet’. ‘Jongmoo’ and ‘Ruffled Satin’ had flowers with crimson color. Therefore, the new cultivars with unique flower colors were a promising cultivars to a woody landscape plant. Cultivars with large flower sizes were Hibiscus hybrid ‘Daewangchun’, Hibiscus hybrid ‘Daemang’, and Hibiscus hybrid ‘Jina’. H. syriacus ‘Ggoma’, ‘Mibeak’, ‘Antong’, ‘Lil Kim’, and ‘Eunhasu’ had small flower sizes. Cultivars with long red eye were H. syriacus ‘Hunjang’ and H. syriacus ‘Hi Lea Red’. Therefore, the new cultivars, Hibiscus hybrid ‘Daewangchun’, Hibiscus hybrid ‘Daemang’, Hibiscus hybrid ‘Jina’ with large flower sizes, H. syriacus ‘Ggoma’, ‘Mibeak’, ‘Antong’, ‘Lil Kim’, and ‘Eunhasu’ with small flower sizes, H. syriacus ‘Hunjang’ and H. syriacus ‘Hi Lea Red’ with long red eye, were promising cultivars to a woody landscape plant.

Objectives: This study was performed to evaluate the antistress effects of two aromatic blends being composed of synergic essential oils and also to differentiate its effectiveness between two. Methods: The subject were 20(10 for men, 10 for women) for vital factors and another 20(10 for mem, 10 for women) for serum catecholamine. Vital factors(blood pressure, pulse), electroencephalograpy, psychological tests(SACL, STAI) and serum catecholamine were applied to the subjects. Results: 1. All two aromatic synergic blends revealed no significant differnce of vital factors after inhalation but stable conditions generally by lowering pulse and blood pressure after inhalation. 2. Both blends were significantly valuable in antianxiety and antistress effects statistically. There were no statistically difference between two blends. 3. There were no significant difference in all brain waves after inhalation of two blends but generally stable brain waves were seen in all areas. 4. There were antistress effects of both blends in accordance of decreased serum catecholamines after inhalation of both blends. There were no significantly difference between two blends statistically. Conclusion: Both two aromatic synergic blends reached effective antistress and antianxiety states after inhalation of each blends. There were no siginificant difference between two blends. Further studies about the effectiveness between the amount of aromatic essential oils and the duration of inhalation should be considered. Also clinical applications of these two aromatic synergic blending oils to develop the aromatic products would be affordable in the future.

This paper evaporates PbTiO₃layer thickness differently with RF sputtering method on Si Wafer(n-100). This study is performed to examine the characteristics of electric constant, photon energy and dielectric loss according to the thickness of PbTiO₃and increase the reliability and reproduction of PbTiO₃thin film. It is confirmed that the variation of electric constant by frequency resulted from the formation of particles within thin film, the particle size and the polarization on grain boundary. In conclusion dielectric loss depends on the value of imaginary number (ε2), polarizability falls zero(o) by resonance absorption and is close to 0 of tan8 value and Q value of dielectric loss.

New technology has always carried two faces, which are the opportunity and the crisis. Intranet, recently appeared in the computing world, is being accepted as a replacement of traditional Client/Server technology. Since intranet has not been completely built even in its concept, it will give a company the crisis rather than the opportunity. To take the new opportunity for a business and organizational innovation through the intranet, its builder should necessarily acquire the knowledge of the preliminary considerations to the building. The purposes of this article are to define the concept of intranet, to investigate the cases and the building methodologies, and to discuss the preliminary considerations to the building.
