본 연구에서는 분자량이 다른 순수 천연고무 용융체와 다양한 유형의 카본블랙을 혼합한 배합고무 융용체의 탄성반응을 조사하였다. 또한 카본블랙과 고무 분자와의 상호작용과 이들 탄성반응이 갖는 상관성을 규명키 위해 입자의 크기와 구조가 다른 카본블랙을 대상으로 결합 고무를 측정하였다. 카본블랙의 함량이 증가할수록 결합고무는 증가하였고 특히 카본블랙 입자의 크기가 작아 비표면적이 넓고 구조가 발달될수록 증가하였다. 카본블랙을 혼합한 배합고무 용융체의 탄성반응은 순수고무의 경우에 비해 크게 향상되었으며 특히 결합고무가 큰 경우에 보다 현저하였다. 순수고무 용융체의 분자량이 증가할수록, 그리고 고무에 혼합된 카본블랙 입자의 크기가 작을수록 응력이완 거동은 지연되었으며 복원거동은 보다 탄성적으로 변하였다. 영구변형 거동에 있어서는 고무 분자량이 감소하고 카본블랙 입자 크기가 증가할수록 그 변형정도가 커졌다. Elastic responses on both pure natural rubber melts with different molecular weights and the rubber compounds mixed with various types of carbon blacks were investigated in this study. Furthermore, the degree of bound rubber was measured for various carbon blacks with different sizes and structures in order to study the interaction between the rubber and carbon blacks, and to study the correlation between the interaction and the elastic responses. As a loading amount of carbon black increased, the degree of bound rubber became higher, particularly for carbon-black particles with smaller sizes and higher structures. The elastic responses of the rubber melt filled with carbon black remarkably improved, as compared with those of unfilled rubber melt, specially in carbon black showing higher contents of bound rubber. Stress relaxation was more delayed and recovery behavior became more elastic, as the molecular weight of the rubber melt increased and the size of carbon-black particles was decreased. Permanent set became higher, as the molecular weight of the rubber melts decreased and the size of carbon-black particles increased.

The research investigates the effect of extracurricular activities to self-esteem and is classified into three factors: -physical factors, artistic factors, and intellectual factors. They were analized by the effects of self-physical, self-effect, self-esteem and self-achievement. The children who have extracurricular activities more than 2 times a week(each at least 50 mins after school). We used a self-physical survey report, a self-effect survey report and a self-esteem survey report as the method of research. However, we excluded some insincere survey datas such as double entrys or blank entrys, only secure data was included and analized by SPSS 10.0. We reach some conclusions from the collected datas used by a standard variance, a analysis of reliability, multiful response cross-tab, one-way anova, correlation, multiful regression followed as below; 1. The school childrens extracurricular activities on participation characteristics shows that depending on sex, family income, the intellectual activities, artistic activities, physical activities follow the academic level of the children in school. Also it shows that the physical activities of school children decrease as the increase in grade. 2. The psychological characteristics follow the dynamic statistic of population and the academic year, it shows the small contrast that is: first, the self-esteem depends on the family income and the academic year. second, the self-effect depends on sex, family income and the academic year. third, the self-physical depends on family income and the academic year. fourth, the self achievement depends on family income, parents academic background(especially mother`s) and the academic year. 3. The psychological characteristics follows the form of activities after school. It shows the small contrast in self-effect, self-physical and self-achievement. 4. We found that there is a high mutual relationship between the psychological characteristic factors. The self-esteem was getting higher as the children improved in self-physical, self-effect, and self-achievement through the extracurricular activities after school.

In this study, the microstructure of the CVD-fabricated Cu(In,Ga)Se₂ (CIGSe) absorber layer by simulating the stacking sequence used in a co-evaporation method, and changes solar cell performance were investigated. The absorber layer prepared by stacking CuSe and (In,Ga)Se between InSe is separated into Ga-free CuInSe₂ and Ga-rich CIGSe, and transformed to CIGSe by selenization heat treatment with slight improvement in the the solar cell efficiency. However, in CVD, since the supply of liquid Cu-Se is not as active as in the co-evaporation method, the nanoocrystalline layer containing a large amount of Ga remained independently in the absorption layer, which acted as a cause of the loss of JSC and FF. Therefore, by using a precursor structure in which CuGa is sputter-deposited on a single layer of InSe deposited by CVD, performance parameters of VOC, JSC, and FF could be greatly improved.

본 논문에서는 포터블 뇌파 바이오피드백시스템을 위한 전치증폭부 및 디지털 신호처리부의 하드웨어 구현에 대한 연구를 수행하였다. 뇌파의 특성을 고려하여 외부 잡음을 제거할 수 있는 뇌파 획득용 전치증폭부를 구현하였다. 측정된 뇌파에는 안전도, 근전도, 심전도 등의 신호들이 포함되어 있으며 이들은 뇌파 분석에 방해가 된다. 따라서 이러한 신호들을 제거하기 위하여 적응여파기 알고리듬을 수행하고 전치증폭부를 실시간으로 구동하는 디지털신호처리부를 구현하였다. 시뮬레이션 파형과 실제 뇌파를 적용한 실험결과를 통하여 개발된 시스템의 성능을 확인할 수 있었으며 휴대형 뇌파 바이오피드백 시스템에 적용 가능함을 확인하였다. In this study, we carried out a study for implementation of the pre-amplifier and the digital signal processing part for the potable EEG biofeedback system. As we consider characteristics of the EEG signal, we designed the pre-amplifier to obtain the EEG signal to be reduced noise signal. Because the EEG signal include EOG, EMG, ECG signals etc, it is difficult to analyze of the EEG signal. Therefore, we developed DSP board and operation program which was embed the LMS adaptive filter algorithm and operate with the pre-amplifier in the real time. The simulation signal and pure EEG signal is used in the experiment. As the result, we confirmed good efficiency of developed system and possibility of application to the portable EEG biofeedback system.

For the hydraulic model experiment, hydraulic properties of the existing spillway were reviewed to derive the optimal design solution in the auxiliary spillway to be constructed newly and hydraulic experiments were conducted by dividing the said model experiment into the experiment 1 and the experiment 2. The results for the experiment 1 as a design scheme found that the discharge capacity was fairly good. In addition, in the approach channel, the approach velocity was observed to be within the tolerance; however, it was revealed that it is necessary to make a supplement by changing the shape of the training wall as an eddy current was generated by the training wall. In the spill water, the pressure of the generating portion was analyzed within the allowance. and it was found to be necessary to improve the shape of the control unit as well as the flow incoming from the spillway to the tunnel section to be properly distributed. The result for the experiment 2 as a design scheme showed that the discharge capacity was very good. Additionally, in the approach channel, the approach velocity was found to be within the tolerance and to improve the central peer shape. In addition to that, in the spillway, it was shown that the pressure of the generating portion reaches within the allowance and a single discharge capacity as an auxiliary spillway for a constant discharge (about 4500 ㎥/s) is secured. Further, it was analyzed that the tunnel inflow is secured and the tunnel section secures the water level less than 70% even during PMF. In the experimental results for the design schemes: the experiment 1 and the experiment 2, it was demonstrated that in the experiment 2, unique features of the spillway structure and risky factors affecting the safety due to the tunnel tubing phenonenon were improved.
