The unique properties of graphene have earned much interest in the fields of materials science and condensedmatter physics in recent years. However, the biological applications of graphene remain largely unexplored. In this study, we investigated the conditions and viability of a cell culture exposed to graphene onto glass and SiO2/Si, using a human nerve cell line, SH-SY5Y. Cell viability was 84% when cultured on glass and SiO2/Si coated with graphene as compared with culturing on polystyrene surface. Fluorescence data showed that the presence of graphene did not influence cell morphology. These findings suggest that graphene may be used for biological applications.

본 논문에서는 인공지능분야에서 지능을 구현하는데 중요한 개념인 Minsky의 "Mind of Society"를 인간의 뇌를 모방하여 생리학적 뉴런구조를 바탕으로 하여 지능을 구현하려는 인공 신경망과 결합하여 지능적인 퍼지 학습 알고리즘을 제안하였다. 지능 퍼지 학습 알고리즘의 학습구조는 생리학적 뉴런 구조에서 흥분책을 분석하여 퍼지 논리학습 구조로 구성하였다. 즉, 본 논문에서 제안한 학습 알고리즘은 억제 뉴런구조를 전방향 억제 뉴런과 역방향 억제 뉴런으로 구분하여 전방향 억제 뉴런을 퍼지 논리곱 구조로 역방향 억제 뉴런구조를 퍼지 논리 부정 구조로 구성하였다.

전사개시 단계중에 삽입되는 N말단의 methionine이 제거되고 pelB signal sequence를 삽입하여 인체 epidermal growth factor (hEGF)가 직접 분비발현 되도록 고안된 T7과 tac promoter에 의하여 각각 발현되는 pYHB101과 pYHB2를 제조하였다. 또한 T7 promoter에 의하여 발현되지만 signal sequence를 삽입하지 않은 pYHB1도 제조하여 각각 제조된 재조합 plasmid들의 발현 및 분비효율을 비교하였다. pelB signal sequence hEGF 유전자를 갖도록 제조된 pYHB101을 포함하고 있는 균주가 pYHB1보다 균체 성장속도는 낮았지만 pYHB101을 1 mM IPTG로 5시간 induction 하였을 때 13 mg/l의 rhEGF가 분비발현되어 T7 promoter의 발현 체계를 갖는 경우가 tac promoter보다 높은 발현 효율을 보였다. 이때 pYHB101에서 발현되는 rhEGF의 발현량은 준최적 조건에서 14 mg/l이었다. We have designed nucleotide sequences of hEGF structural gene to eliminate the N-terminal methionine residue incorporated during the translation initiation step, and constructed recombinant human epidermal growth factor (rhEGF) secretion plasmids pYHB101, and pYHB2 in which pelB signal sequence-hEGF gene was expressed under the control of the T7, and tac promoter, respectively. We also constructed pYHB1 vector which contains rhEGF gene controlled by T7 promoter. The transformant with pYHB101 showed relatively slow growth pattern compared to the transformant with pYHB1. However, we observed that the transformant with pYHB101 secreted rhEGF of 13 mg/l significantly after 5 hr induction with 1 mM IPTG and that the T7 promoter was more effective than tac promoter when connected to pelB signal sequence. The amount of rhEGF was 14 mg/l under the sub-optimized condition.

Since services in ATM networks are very various and the characteristic of traffic from services is very different from each one, shared buffer mechanism, that shares only one buffer, cannot satisfy QoS, requirement for traffics. Furthermore, it has more difficulty in controlling composite cells in buffer when large ATM switch is implemented. In this paper, we propose cell service scheduling of separated routing allocation mechanism that allocates respective, independent buffer to cells with same traffic characteristic according to priority. We analyzed its performance using computer simulation. Then, we obtained cell loss probability changing buffer size and weighted value, when cell service scheduling is done by unsymmetrical round-robin depending on weighted value that is allocated to respective buffer.

This paper proposes a spatially distributed control scheme for a multi-layered cellular system to achieve flexible and high capacity wireless communication system under any traffic conditions including nonuniform traffic conditions. In the proposed system, terminals with lower mobility are connected to the wideband microcell systems to support variety of service including high bit rate data transmission and terminals with higher mobility are connected to the narrowband macrocell systems to reduce delay. To flexibly cope with temporal and spatial variations of traffic conditions, the ratio of the microcell and macrocell terminals as well as system bandwidth are adaptively and autonomously shared by both system Numerical simulation confirms that proposed scheme expressed flexible distributed location.

The power line channel has time-variant characteristics caused by various kind of electrical devices. This characteristics are synchronized with the main voltage by their own characteristics. The main factors of disturbance are the variation of the channel impedance and noises, In other papers [2] [3], the synchronous noise modeling has been achieved. But the modeling is not satisfied simultaneously with the time domain and the frequency domain and there are not any discussion about short-term variations of the channel impedance which cause to the signal fading. Therefore, this paper researched to solve problems about the signal fading by analyzing the short-term variation of the channel impedance, and proposed the synchronous noise modeling which is satisfied simultaneously in the time domain and the frequency domain.

The purpose of this study was to identify the difference between the Whole Body Reaction Time at offensing movement and that at defencing movement among three age groups of male fencing players. The subjects of this study were twenty-eight male fencing players in Taejon City(10 middle school players, 10 high school players and 8 collegiate players). Base upon the results of this study, the following conclusions were obtained. 1. Whole Body Reaction Time at offensing and defencing movement showed fast record in the order of high school group, college group and middle school, but there was no significant difference. 2. Whole Body Reaction Time at offensing movement showed fast record in the order of college group, high school group and middle school. And there was significant difference between college·high school group and middle school group in the comparison of offensing WBRT. 3. Whole Body Reaction Time at defencing movement showed fast record in the order of college group, high school group and middle school. And there was significant difference between college·high school group and middle school group in the comparison of defencing WBRT. 4. WBRT at offensing movement was faster than that of defensing movement. But there was no significant difference between offense movement and defense movement in the comparison of WBRT.
