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.

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.

The purpose of this study is to survey and analyze on promotional measures of direct foreign investment from, Korean Exporting enterprises. Korean, the continuous export increase in an inevitable subject to our country aiming at realization of a society of high degree industry in the 1980's according to the ecnomic development strategy taking the lead in export. However, the competitiveness of our country had resently become clear, on the basis of analyzing the transition that is gradually worsening from the comparative predommence of export goods of past time.- compared with some important countries such as Taiwan, Hong Kong, Singapore, Philippine etc., due to sudden rise of wage, price export cost etc., and to the prospect that the competition against Red china is expected to become intense in the near future. Also the good old days-will soon be gone when most lines of production enjoyed full protection-and blessings from the government as far as their competition with overseas rivals was concerned. The good news is that our domestic manufactures will be challenged to show greater quality and fidelity to better serve the interest of consumers, the bad news is the some of our vulnerable industries might have to cop out. At the time, the Korean direct foreign investment are important to the Korean economy. Now, the important of direct investment lie in the role of tranferring technology and modern industrial techniques. It was in the 1977s, as Korean began to develop its chemical and heavy industrial. sectors, that the need for foreign technology, and management skills became great. In addition, Korea was then trying to diversity her export markets, and the links with multinational firms involved in direct foreign investment gave her a greater access to foreign markets. As a result of these environmental factors, the decisive measures were taken to encourage direct foreign investment in the 1970s. In general, the Government played an active role in determining the industrial structure of Korea during the 1970s. It did this, first by maintaining tariff walls and quantiative import barriers in their early stages of development; Second, by providing certain industries with a variety of incentives to stimulate their exports, and finally, by protecting them from direct competition with foreign technology. Thus, althouth there was liberalization of foreign trade to same extend and investment regimes in the 1970s, it was highly selective. Also, our direct foreign investment is insufficient in the sale as well as in the contents, and still does not get out of the infant stage in comparison wi th the developed countries. In this thesis, therefore, I should like to suggest several measures for promoting direct foreign investment as follows; (1) In consideration of the lack of national resources the direct foreign investment must be increased in quantity and quality in order to continue to expand the export. (2) The direct foreign investment must go forword in connective with domestic industrial policy, foreign trade policy and resource policy. (3) The aim of the direct foreign investment shouldlie in the long-term advantage of national economy rather than the shorterm profits of each enterprise with a view to increasing the exports and securing the natural resources through the direct foreign investment. (4) As the capital, technology and labor may be transferred by the direct foreign' investment, the closer cooperation with foreign countries in which Korea had intentions: to invest must be made politically, economically, socialogically, and cuturally. (5) The Korean government should expand the related supporting system. This can be done by establishing a powerful organization exclusively charged with supporting the areas of fiances, taxation, investment insureance, and information. As abovemented, to promote our direct foreign investment our government policy must lay emphasis on maximizing the efficency of the foreign investment on the long-term basis rather than the short-term basis.

This study investigated the permanent deformation of dental rubber impression materials in order to evaluate their degree of recovery from displacement during removal through undercut area. We also investigated the stain in compression in order to evaluate the materials' flexibility during removal from the month, or during removal of the cast from the impression. Additional silicone, polyether, and polysulfied rubber impression materials were tested for their properties of permanent deformation and strain in compression according to the testing methods of the ADA specificaltion no. 19. 1.The permanent deformation values were as follows: polysulfide (2.25%), polyether (2.14%), and additional silicone (0.28∼1.21%, 2.38% for Perfect F). Examix, Express and Provil, which are additional silicone rubbers, showed lower permanent deformation values of 0.29%, 0.28% and 0.34%, respectively. Perfect F, although it is an additional silicone rubber, showed the highest permanent deformation value (2.38%) within the tested materials. 2.The strain in compression values were as follows: polysulfide (10.63%), additional silicone (2.88∼10.09%), and polyether (2.38%). The additional silicone rubber samples showed various values. Contrary to our expectations, it is also notable that Vinylate, which is used when taking an one-step impression, had higher stain in compression value (10.09%) than the light body impression materials even though it is classified as a heavy body material. Express (a.s.) had a low strain in compression (2.88%) which is similar to that (2.83%) of Impregum F (p.e.). In light body rubber materials, Permlastic had the highest value (p.s. 10.63%), followed by Perfect F (a.s. 7.38%), Correct VPS (a.s. 7.13%), Examix (a.s. 6.04%), Provil (a.s. 3.82%) and Express (a.s. 2.88%). Although the tested materials showed various values, all of them satisfied the requirements of A.D.A. Specification No. 19, which require that permanent deformation be less than 2.5%, and strain in compression be between 2∼20%.

Korean Medical Licensing Examination(KMLE) 2002 focused on evaluation of the integrative medical knowledge such as primary clinical care or problem-solving competence. We analyzed the correlation among the year-wise student academic scores(grade score), trial examination scores and KMLE score by correlation analysis and multiple regression method. Four times of trial examination were taken in 2001, which were composed according to the principles of KMLE. Trial examination scores were significantly correlated with student grade scores (p(0.05). KMLE score also correlated with student grade score a nd trial examination score. The grade score at senior had higher correlation coefficient than the grade score at junior in correlation analysis. In multiple regressions, grade score at senior and mean score of trial examinatio n score were significant variants affecting KMLE score. Based on this result, regression formula such as [KMLE score] = 110.596+21.449^*[6th grade score of student] + 0.577^*[mean of trial examination score] was established (R2=0.764, p<0.001). Our results show that the trial examination is useful evaluation tool for final assessment of medical achievements. Also a trial examination is used as a reference data for student guidance and control in preparing for KMLE.
