  • Many investigations about the dynamic analysis of the structural system based on the BBA(Building Block Approach) method which predict dynamic characteristics of synthesized structures from each structure. But it is actually sometimes difficult to remove mounts from structures. In this paper, TFSM(The Transfer Function Separation Method) is developed which can predict dynamic characteristics of separated structures from the data of vibrational experiment of the synthesized structures. By combining TFSM with BBA, this paper also proposes the method which can predict dynamic characteristics of mount-modified structure without removing mounts from structures. And the proposed method is verified by the experimental data of plates.

  • Purpose: The purpose of this study was to develop standard syllabuses of 4 subjects (Structure and Function of Human Body, Pathogenic Microbiology, Pathophysiology, Mechanisms and Effects of Drug) of bionursing. Methods: We developed standard syllabuses of 4 subjects through 3 step discussions and analysis. At first each committee for 4 subjects made the syllabus, after then all researchers discussed together. Finally each committee concluded final one. Committee members consisted of professors who teach that subject at nursing college. Results: Standard syllabus for Biological Nursing I-1 or Structure & Function of Human Body I consisted of 3 parts and 9 themes and for Biological Nursing I-2 or Structure & Function of Human Body II was 3 parts and 9 themes. Standard syllabus for Biological Nursing II or Pathogenic Microbiology consisted of 8 themes and Biological Nursing III or Pathophysiology consisted of 2 parts and 19 themes. Standard syllabus for Biological Nursing IV or Mechanisms & Effects of Drug consisted of 2 parts and 13 themes. Conclusion: The standard syllabuses and titles of 4 subjects of bionursing need to be disseminated to all the nursing college by Academy of Korean Biological Nursing Science. Further researches to investigate curriculum for bionursing and to identify the effects of 4 standard syllabuses were recommended.

  • Two fluoro-substituted 2-pyrazoline derivatives, 1-phenyl-3-(4-methoxyphenyl)-5-(4-fluorophenyl)-2-pyrazoline (1) and 1-phenyl-3-(4-methoxyphenyl)-5-(2-fluoro-phenyl)-2-pyrazoline (2) have been synthesized and characterized by elemental analysis, IR, UV-Vis and fluorescence spectra. The crystal structure of 1 has been determined by X-ray single crystal diffraction. For the two compounds, density functional theory (DFT) calculations of the structures and natural population atomic charge analysis (NPA) have been performed at B3LYP/6-311G** level of theory. By using TD-DFT method, electron spectra of 1 and 2 have been predicted, which are very approximate with the experimental ones. Comparative studies on 1 and 2 indicate that the location change of fluorine atom in 5-position phenyl ring of 2-pyrazoline does not make significant change of geometries and electronic transition bands, but it leads to evident change of atomic charge distributions and peak intensities of UV and fluorescence spectra.

  • In this paper, we use time-frequency localization analysis method to analize the target function and the area of the target space. When we analize the function with the time and frequency axis simultaneously, the characteristic of the function is shown more precisely and the area is covered by a certain block. After we analize the target function in the time-frequency space, we can decide the activation functions and compose the hidden layer of the RBFN by choosing the radial basis function which can represent the characteristic of the target function, RBFN made by this method, designs the good structure proper to the target problem because we can decide the number of hidden node first.

  • Objectives: In this study, we examine whether Sasang constitutions include all 8 attitude-function types, forming a complete paradigm from the perspective of Jungian psychological type theory. Methods: Analysis of the meanings of psychological attitudes and function of each Sasang constitution was performed, comparing them with the typological theories of C.G.Jung and John Beebe, both of whom are eminent minds in Jungian typology. Results and Conclusions: (1) Each Sasang constitution had all 8 psychological attitude-function combinations, which are diversely differentiated by type within their conscious and unconscious psyches. This is likely because attitudes and functions that develop in the conscious mind build up compensating attitudes and functions in the unconscious. (2) It seems that extroversion and introversion coexist within every Sasang constitution as psychological descriptions reported by Lee, Je ma state. The superior and inferior functions are disposed in the order of organ size in Sasang constitutions, but dominance of extroversion or introversion as defined by Jung's concepts of attitude does not seem to be determined by constitution.

  • 본 논문에서는 고속 ATC(Automatic Threshold Control) 회로 구조를 고안하고 이를 이용하여 고속 ATC 기능을 갖는 버스트 모드 제한증폭기를 설계하였고, $0.8{\mu}m$ SiGe BiCMOS 상용 파운드리 기술을 이용하여 제작하였다. 제작된 버스트 모드 제한증폭기는 $PRBS=2^7-1$에서 무에러(error free)의 아이를 보였고, 160ps이내의 지터 특성과 95ps이내의 상승/하강시간을 보였다. ATC특성 측정결과 버스트 데이터의 신호의 초기부터 안정되게 파형을 잘 잡아낼 정도로 빠른 ATC동작이 이루어지고 있어 고안한 ATC회로의 고속특성을 확인할 수 있었다. 그러나 버스트 초기에서 듀티사이클 왜곡이 발생했고, 입력 신호의 크기가 커짐에 따라 듀티사이클이 59%까지 증가하는 특성을 보였다. 그러나 10 사이클이 지난 후에는 모든 입력 신호의 크기에 대해 듀티사이클이 52% 이내로 안정화되고 있음을 확인하였다

  • This study was conducted to evaluate the non-timber forest functions of the Research Forest area of Kangwon National University. In this study, forest recreation function was investigated through survey method answered by forest management experts. The evaluation factors for forest recreation function were separated into external and internal factors. Each factor was classified into intermediate element and detailed element. Therefore in this study, the evaluation factors of forest recreation function were divided into two groups which are the potential of external factors and the suitability of internal factors. Potential of the external factors were divided into accessibility, location, landscape and induction factors while the suitability of internal factor was divided into stand structure, forest structure and human impact. The priority of the potential of external factors was in order that location, accessibility, induction factors and landscape. The most important factors for the location, accessibility, induction and landscape factors are based on regional characteristics.

  • 우리나라의 주택용 전력요금체계는 전력 사용량이 증가함에 따라 가격이 상승하는 구간별 가격체계의 특징을 보이고 있다. 우리나라의 현행 요금체계는 선진국의 경우보다 과도한 누진체계를 갖고 있어, 누진제 완화에 대한 논의가 이어져오고 있다. 기존 국내의 주택용 전력수요함수 추정에 대한 연구는 구간별 가격체계 하에서 주택용 전력수요함수를 추정함에 있어 소비자의 예산제약선이 선형이 아닌 굴절되는 형태를 갖게 된다는 점, 구간별 가격체계 하에서 소비자가 인식하는 가격이 과연 경제학 이론대로 한계가격인가에 관한 점, 가격변수의 내생성에 대한 문제 등을 충분히 고려하고 있지 않은 경우가 많다. 이에 본 연구는 주택용 전력수요함수를 올바르게 추정하여 그 결과를 바탕으로 누진제 완화에 대한 시나리오 분석을 수행하고자 한다.
