  • 고도의 정보사회가 될 것으로 예견되는 21세기 전 세계는 창의적이고 원천적인 과학기술을 지속적으로 창출하면서 선진적 우위확보를 위해 치열한 경쟁을 벌이고 있다. 우리나라도 지금까지 이룩한 경제성장을 발판으로 이제부터는 더욱 생산적이고 독창적인 세계 일류 지식과 과학기술을 창출해 내야 할 위치에 있다. 세계적으로 새로운 지식은 대부분 학술지와 도서를 통해 발표되고 있으며, 미국의 과학정보기구인 ISI(Institute for Scientific Information)는 세계의 우수 학술지를 평가하여 그 중에서 가장 영향력이 높은 3~4%의 학술지를 SCI(Science Citation Index), SSIC(Social Science Citation Index), AHCI(Arts and Humanities Citation Index)로 전별하여 발표하고 있음은 잘 알려진 바와 같다. 우리 학계에서도 수 년 전부터 연구업적 등의 평가에 이들 분류를 적극 활용하고 있으며, 개개의 연구자들도 연구성과를 SCI 등에 등재된 학술지에 발표하기 위한 노력을 배가하고 있는 실정이다. 그러나 안타까운 것은 우리나라에서 발간되는 학술지 중 과학기술 분야 단 5종만이 SCI에 등재되어 있을 뿐이어서 우리의 학문이 세계적으로 교류되고 인정받는데 상대적으로 불리한 위치에 있다는 사실이다. 국내 학술지가 이들Index에 등재될 경우 우리의 연구성과가 보다 빠르고 쉽게 국제적으로 소개.인정되며, 이는 우리의 과학기술 수준을 한 단계 높이는데 첩경이 될 것이라는 점은 의심의 여지가 없다. 과학기술 평가과정은 측정 가능한 연구투자와 연구결과 현상으로 간주할 수 있는데, 일반적으로 연구투자는 연구투자에 필요한 모든 요소들이 실체적이며 평가하는 데에 있어서 인력, 재정 자원, 장비, 재료, 건물 등과 같이 구체적이고 경험을 요구하지 않기 때문에 그 모든 연구결과보다 평가하기가 용이하나 과학기술의 연구결과는 연구 과정을 통해 보다 비실체적이고 양적으로 측정하기 어려운 지식으로 구성되어 있어 평가하는데 어려움이 뒤따른다. 과학기술 연구결과를 양적이나 질적으로 측정하는데 있어 일반적으로 이용되는 시스템은 없으나 국가의 과학기술 수준은 보통 그 나라 과학기술 활동의 연구결과를 과학기술 생산성이나 연구결과물 즉 논문 등의 출판을 통한 배포나 인용분석 등에 기초한 양적 평가지표를 이용해 측정하는 서지적 방법에 의해 평가되고 있다.연구활동 결과로 발표된 연구논문은 새로운 연구논문의 자료로 인용되게 되는데, 일반적으로 인용이 많이 된 논문일수록 질적인 가치가 높다고 하므로 논문의 발표량과 인용된 횟수는 연구활동을 평가하는 척도로 활용점에 따라 과학기술분야 논문의 국가별, 기관별, 분야별 논문수와 피인용도는 과학기술 수준 평가의 척도가 될 수 있으며 이러한 평가는 과학기술 정책 수립 및 투자, 연구활동에 대한 평가 등의 중요한 자료로 활용될 수 있다. 과학기술분야 전반에 걸친 SCI 기반의 NSI, NCR 데이터베이스를 분석하여 우리나라 과학기술분야의 수준을 평가할 수 있는 지표를 산출하여 우리나라의 과학기술 수준을 정확히 파악하고, 세계 추세를 분석하여 앞으로 나아갈 정책방향을 설정하는데 도움이 되도록 하며, 국내 기관별, 분야별 분석을 통하여 과학기술 수준을 평가할 수 있는 객관적인 자료를 제공함과 동시에 국내 연구 인력간의 건전한 경쟁을 유도하여 과학기술 발전에 기여하고자 한다.

  • The objective of this study was to investigate the site and growth characteristics of dominating Cornus controversa in the hardwood stands at Mt. Gariwang and Mt. Joongwang area located in Pyungchang-gun, Kangwon-do. The C. controversa was mainly distributed at the rather steep slope and aspect facing from northeast to northwest, and altitudes ranging from 800 to 1,100m. The C. controversa grew at relatively deep A soil layer with high moisture and nutrients. Major competing species in upper stories were Quercus mongolica, Acer mandshuricum, Salix hulteni, Acer pictum, and herb plants such as Polystichum tripteron, Dryopteris crassirhizoma, Meehania urticifolia, Pseudostellaria pahbiniana, Ligularia fischeri, Impatiens noli-tangere, Corydalis speciosa in the floor. The average annual diameter growth of C. controversa according to the altitude was $4.06({\pm}0.90)mm$ below 900m, $2.51({\pm}0.65)mm$ from 900 to 1,000m, $3.28({\pm}0.12)mm$ from 1,000m to 1,100m and $2.81({\pm}0.35)mm$ above 1,100m. Good annual growth was shown at northwest site, but no difference due to micro-topography.

  • Three-dimensional quantitative structure-activity relationships (3D-QSARs) on the fungicidal activity against damping-off (Pythium ultimum) with N-phenylbenzenesulfonamide and N-phenyl-2-thienylsulfonamide analogues (1-34) were studied quantitatively using CoMFA (comparative molecular field analysis) and CoMSIA (comparative molecular similarity indeces analysis) methodologies. On the whole, the statistical qualities of CoMSIA models with field fit alignment (FF1-FF5) were slightly higher than that of atom based fit alignment (AF1-AF5) but, the deviations of statistical quality between two alignments in case of CoMFA models were slightly lower. The statistical results of CoMFA and CoMSIA model showed that the optimized CoMSIA model (FF1: $r_{cv.}^2\;(q^2)=0.674$ & $r_{ncv.}^2=0.964$) for damping-off is better predictability and fitness for fungicidal activities than CoMFA model (AF5: $r_{cv.}^2\;(q^2)=0.616$ & $r_{ncv.}^2=0.930$). The fungicidal activities according to the information of the CoMSIA (FF1) model were dependence upon the electrostatic and hydrophobic field of the N-phenylbenzene sulfonamide analogues. Therefore, from the results of graphical analyses on the contour maps with CoMSIA (FF3) model, it is expected that the characters of R4-substituent on the N-phenyl ring as hydrophobic and hydrogen bond acceptor will be contributed to the fungicidal activity against damping-off.

  • The minimum structural requirements of R-phenoxy substituents for herbicidal evaluation of O-(2-(R)-phenoxy)-ethyl-N-aralkylcarbamate (1-15) analogues against phytoene desaturase (PDS) based on the three dimensional quantitative structure-activity relationships (3D-QSARs: CoMFA and CoMSIA) were studied quantitatively. The correlativity and predictability ($r^2_{cv.}=0.753$ and $r^2_{ncv.}=0.964$) of the CoMFA 1 model were higher than those of the rest models. The PDS inhibitory activities from the optimized CoMFA 1 model were depend upon the steric field (44.0%), electrostatic field (36.3%), and hydrophobic field (19.6%) of O-(2-(R)-phenoxy)ethyl-Naralkylcarbamate analogues. From the CoMFA contour maps on the structure of the most active compound (5), if it has the steric favor at meta-, para-position on the phenoxy ring, the negative charge favor in meta-position and positive charge favor in the outside part of para-position, the inhibitory activity will be predicted to increase. Also, if ortho-, para-position, and outside of phenoxy ring are hydrophilic favor, and meta-position is hydrophobic favor, it is predicted that the inhibitory activity against PDS will be able to increase.

  • This experiment was conducted to find out the effects of the six different feeding methods on the development of body weight, testis, comb and pituitary gland, and the sexual maturity of White Plymouth Rock cockerels. From hatching to 22 weeks of age, the weights of whole body, testis, comb and pituitary gland, and the histological changes of testis and the semen characteristics were checked every other week. The results obtained in this expeniment were as follows: 1. The growth rates of the self-feeding groups were faster than those of the limited feeding groups (70 percent of the self-feeding) by about 2 weeks. The weights of testis and comb showed the most marked increase at 20 weeks of age in the self-feeding groups and at 22 weeks of age in the limited feeding groups, respectively. 2. The weights of pituitary gland from hatching to 22 weeks of age at all observation weeks were not recognised significantly among the compared groups except 4, 14 and 16 weeks of age. 3. Correlations between week of age, body weight, testis, comb and pituitary gland, in the course of 22 weeks, were highly significant. 4. The diameters of lumina and tubules in the seminiferous tubules increased very slowly until 10 weeks of age. They showed the most marked increase at 12 weeks of age in the self-feeding groups and at 14 weeks of age in the limited feeding groups, and then continuously increased until 32 weeks of. age. 5. Primary spermatocytes appeared at first at 8 weeks in the all treatment groups, Secondary spermatocytes appeared at first at 10 weeks in the self-feeding groups and at 12 weeks in the limited feeding groups. At 14 weeks of age spermatids and spermatozoa were found at first in the self-feeding groups but spermatids were found in the limited feeding groups. 6. Age of the first ejaculation was between 14 and 16 weeks of age in the all treatment groups. The Average semen. volume and sperm concentration ranged from 0.1-0.2$m\ell$/ ejaculate and 5.6-9.8${\times}$10$\^$8/ sperm/$m\ell$ at the age of the first ejaculation but 0.30-0.35$m\ell$/ ejaculate and 22.4-42.7${\times}$10$\^$8/ sperm int at the 20 weeks of age in the all treatment groups.

  • Since policies of each local government toward regional development have been focusing on only development of the individual applied items such as a character merchandise, co-regional brand, and developing a speciality for the region, the adverse effects of design have been came out. So we carried out this research to minimize the adverse effect of design and also we would like to give the opportunity of thinking of a new way to activate local economy, to create regional identity and to develop local resources by applying the Cl program which have bean used as the way of business improvement coping with the conceptional change of competitiveness with a comprehensive view. Therefore, for design to play an important role in regional development, as standing on the basis of regional development it is necessary to attain the various goals such as activating administrative organization, improving the administrative image, and making the local in go unique. And also it is necessary to develop the communicational strategy as an innovative and expressive program which can consider human network development as an regional resource. To carry out this communicational strategy effectively, in particular, it is not only inevitable to operate the strategic and comprehensive programs promoting the regional development according to the of 6 stages design develop cent program which consists of region's self-verification and self-recognition, self-determination, development of self-innovation, visibility to unify the regional images, creating the design system, and carrying out and verifying the program, but also it is necessary to apply regional development system which can change the regional basic plan, aiming at regional development, into unique regional trait that has an future image by improving the program with constant management and feedback through verifying the design program.

  • Flaxseed (Linum usitatissimum L.), also called linseed and one of the raw materials for making linen, is rich in omega-3 fatty acids, vegetable estrogen, ${\alpha}$-linolenic acid, and dietary fiber. Studies on flaxseed have reported various additional effects, such as the inhibition of cholesterol, blood clotting, and tumor growth. In this study, we investigated the functional components of flaxseed fermented with lactic-acid bacteria. Lactic-acid bacteria was inoculated into heat-treated (roasted) flaxseed and fermented at $37^{\circ}C$ for 72 hr. The fermented flaxseed was extracted with 70% ethanol and the antioxidant effect of the fermented extracts according to the lactic-acid bacteria was analyzed. It was confirmed that the total polyphenol contents had expanded by about 1.5-8 times, and the total flavonoid contents had increased around 1.2 times in the case of fermented flaxseed with lactic-acid bacteria compared to non-fermented flaxseed (NFFS). DPPH radical scavenging and superoxide dismutase-like activities had increased around 5.6 and 2.3 times, respectively, in the fermented flaxseed compared to the NFFS at 100 ppm concentration. The study concluded that fermentation of flaxseed with lactic-acid bacteria is possible and that it is effective to increase the antioxidant effects of flaxseed. These results can be applied to the development of improved foods and cosmetic materials.

  • Juniperus chinensis var. sargentii Henry is a short and creeping evergreen shrub which reaches about 60 cm in height and only occurs in the northeast Asia and in the top of high mountains over the Korea. The Korea Forest Service protects it strictly by law since J. chinensis var. sargentii is an eccentric plant and possibly may be exterminated soon in Korea. This study was carried out to develop the propagation technique by cutting for conservation of genetic resources of J. chinensis var. sargentii. The rooting responses of branch cuttings, obtained from hard(May) and semi-hard wood shoots (August) to four growth regulators, namely, IAA, IBA, NAA and Rooton(exceptionally powder method) applied at various concentrations(0, 100, 200, 500, 1000 and 2000 $mgL^{-1}$) were examined in mixed soil media. Rooting rate showed significant difference between cutting times, among kinds and among concentrations of growth regulators. The optimum cutting time was April to May in hardwood cutting. The application of IBA 1000 $mgL^{-1}$(rooting rate : 36.4%) was most effective in callus formation and rooting of cutting. Relatively, rooting of cutting of the control taken in May was 30.4%. Root characteristics such as number, length and diameter of root were not significantly affected by kinds and concentrations of growth regulators in hardwood cutting.

  • Development education started in some of developed countries of Europe since 1960s. Japan was interested in the development education with realizing the impotance of quality of life in the late of 1970s after high economical growth in 1960s. Just like Eroupe, development education in Japan was done to citizen by development NGOs. But under close cooperation with JICA and MOE, development education was gradually absorbed in formal education. Development education in Japan is done through interdisciplinary studies and the subjects. Geography national curriculum and textbooks in Japan show that the subject aimed to nurture Japanese in the world in the period from the late of 1960s to the late of 1970s. Thus the period can be named the sprouting time of education of development. But with entering the late of 1980s, geography national curriculum started to focus on fostering global citizenship to students. The turn in the educational aims can be counted as practical start of education of development. And education of development through geography was extended the most in the late of 1990s. But in the recent revised geography national curriculum, emphasis on education of development is reduced a little. It can be told that education of development in Japan arrives at the level of the full growth.
