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.

In this paper, we invented a new structure of fast ATC(Automatic Threshold Control) circuit. Using the structure we made a new burst-mode limiting amplifier with fast ATC function using commercial $0.8{\mu}m$ BiCMOS technology. It's ATC function worked so fast that even the first bit of burst-data could be detected, which confirmed that the new structure was useful for fast ATC. However, in the beginning of a burst, distortions in duty-cycle occurred and increased up to 59% of duty-cycle as amplitude of input signal increased. But we confirmed that after 10 cycles passed, duty-cycles was staying below 52% of duty-cycle for any magnitude of input signal.

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.

Block-rate structures are widely used in utility-pricing, including the Korean residential electricity sector. In the case of the current pricing structure, Korean citizens are highly concerned about incurring excessive electricity costs. For these reasons, there have been many discussions concerning mitigation of the strict pricing structure. Existing studies on the residential electricity demand function under block-rate structure have the following three issues - the consumer's budget constraint is non-linear, perceived price under block-rate structure is uncertain, block-rate structure has endogeneity in the price variable. In this context, this paper estimates the residential electricity demand function using micro-level household expenditure data and simulates the impact of alternative block-pricing schedules.
