GMDP 신경모델을 이용한 비선형시스템의 학습속도 개선에 관한 연구

卓漢浩,金昌圭,金炫悳 진주산업대학교 1995 論文集 Vol.34 No.-

The traditional MLPs have practical difficulties: for examle, a large number of units is required and the learning speed is slow. This paper presents a noval neuron model, called Generalized Multi Dendrite Product(GMDP) unit. Multilayer feedforward neural networks with GMDP units are show to be capable of realizing higher-order neural networks. The standard backpropagation learning rule is extended to this neural network. Simulation rules show that single layer GMDP networks provide an efficient model for solving general problems on function approximation.

The purpose of this study is to determine the effect of exercise training on the strength and balance ability of the elderly. The results of this study are: 1) After 8 weeks exercise training, knee muscle strength showed a significant increment. 2) After exercise training, forward functional reach and balance index of KAT 2000 showed a significant increment. Results indicate that strengthening exercise can result in improved muscle strength and balance in the elderly. Further studies are required to show long-term effects of exercise training on the elderly.

In the 21st century, the traffic culture is changing rapidly with the advent of high-speed train and it is called as the traffic revolution age. The policy management for inducing the creativity becomes important for research institutes since the research institutes play an important role in the lead and distribution of new technologies. Therefore, the approach strategy of this investigation is based on the viewpoint of the organizational culture for better performance of research and development through stimulating inducements of creativity and active action of members. A questionnaire survey was performed on five research institutes including a professional railway research institute (PRRI) and four industrial research institutes for the current research, and a development plan for organizational culture of a PRRI has been presented based on the comparison study between two different types of research institutes.

This study was performed to identify personality trait of patients with methamphetamine and alcohol abuse by analyzing MMPI profiles. 93 methamphetamine abuse patients, 59 alcohol abuse patients and 52 healthy subjects completed MMPI. Each MMPI profile in three groups was analyzed by F-test and discriminant function analysis. Alcohol abuse patients showed higher scores n F, Sc(8), and Si(0) profiles of MMPI than the patients with methamphetamine abuse. 3 variables(F, Si, Pd) were discriminated in there two groups. Methamphetamine abuse patients showed higher cores in F. K. Hs(1), Hy(3), Pd(4), Pa(6), Sc(8), and Ma(9) profiles of MMPI than the normal controls. 5 variables (Pa, Pd, Si, K, L) were well discriminated in these two groups. The alcohol abuse patients showed higher scores in F, Hs(1), D(2), Hy(3), Pd(4), Mf(5), Pa(6), Pt(7), Sc(8), and Ma(9) profiles of MMPI than the normal controls, but lower scores in K subscale, 3 variables(F, Pb, Pa) were well discriminated in these two groups. Specially these results indicated that alcohol abuse patients had more psychotic symptoms than methamphetamine abuse patients. These results may suggest that addicted individuals have personality traits to be drug addicts, but it was unclear that these results were ue to predisposing personality traits or results of drug abuse.

정상 보행과 발가락 보행의 하지 근육 근 활성도 비교 : An Electromyographic Analysis3.

김택훈,최흥식,김창인,이진복 한국전문물리치료학회 2002 한국전문물리치료학회지 Vol.9 No.2

This study was designed to identify the effects of walking conditions (normal walking vs. toe-walking) on electromyographic (EMG) activity of gastrocnemius, tibialis anterior, and soleus muscle. Seven healthy adult males participated in this study. The exclusion criteria were orthopedic or neurologic disease, congenital anomaly or acquired deformity, or pain in low back or lower extremities. The maximal voluntary isometric contraction for each muscle was used for the reference contraction, and EMG activity of each muscle during normal walking and toe-walking was expressed as a percentage of reference contraction. The gait cycle was determined with two foot switches, and gait was normalized as 100% gait cycle for each condition. The maximal values of EMG activity in terminal stance (30~50% of gait cycle) of each condition were compared for data analysis. No significant differences were found in EMG activity of the tibialis anterior and soleus (p<.05), whereas significant decrement was found in EMG activity of gastrocnemius during toe-walking compared to normal walking (p<.05). There is a limitation to generalize the results of this study, because small number of subjects participated for this study and only EMG was used for data collection. The treatment methods should be developed to improve gait efficiency by substituting the weakened muscles secondary to upper motor neuron, or by strengthening the distal muscles in lower extremity.

개화기의 국가주의와 1920년대 민족개조론의 관계 연구

김택호 한국현대문예비평학회 2003 한국문예비평연구 Vol.- No.13

The nationalism in 1920's was derived from the desire of finding the spiritual culture thought apart from the material modernity. That was not enough explanation to describe The Theory of Modifying People in 1920's. Actually, the origin of The Theory of Modifying People in 1920's unique thought was from ideologies of modern intellectuals who lived in civilized period of korea. They had both nation-centered idea and elitism, so they strongly tended to think of common people just as an object. The Theory of Modifying People in 1920's showed disagreement with material modernity anti-socialism and critical point of view to the common people. So the Essence of The Theory of Modifying People in 1920's are both the nation-centered nationalism and anti-socialism.

미끄럼 바닥에서 안정성 유지를 위한 균형 전략과 평가방법

Slipping during various kinds of movement often leads to potentially dangerous incidents of falling. The purpose of this paper was to review some of the research performed in the field including such topics as rating scales for balance, kinematics and kinetics of slipping, adaptation to slippery conditions, postural and balance control, and protective movement during falling. Controlling slipping and fall injuries requires a multifaceted approach. Environmental conditions (state of floor surface, tidiness, lighting, etc), work task (walking, carrying, pushing, lifting, etc), and human behavior (anticipation of hazards, adaptation to risks, risk taking, etc) must be accounted for in the assessment of slip and fall-related risks. Future directions of research must deal with modeling of basic tribophysical, biomechanical, and postural control process involved in slipping and falling.

九雲夢硏究

孟澤永 淸州大學校 1983 論文集 Vol.16 No.1

For the bases of the novel Ku-un-mong, two hypotheses are possible. First, the auther Kim Man-Chung, So-po, had a correct understanding of Korean script with which he valued Sa-mi-in-gck as On-so(諺騷), a masterpiece in Korean letters comparable to that of Kul-won. Second, Kim held in his writing the conviction that the good of popular novels could not be denied. In a psychoanalytical interpretation of Ku-un-mong we should keep these in mind; otherwise we are apt to miss the characteristics of the novel. This paper picks out Mother-complex as a motif of the novel and makes it clear that Don-Juanismis is contained in the motif but feminism or homosexuality is not, becaue which was widely present in the writings of the Cho-son dynasty pericd. At the bottom of Kuun-mong lies Don-Juanism which brings the main theme-wealth, rank and fame are in this world found to be but an empty dream-and which conditions the atmosphere of the novel as a fantastic one. The novel, like other fantastic fictions, is interpersed with superhuman actions in an unreal fairly land, which are proved to be a dream. Thus dream is identified with actuality in the classical work. Ku-un-mong seems to be motivated partly by the anxieties of the authors highly respected mother who was a woman of wide knowledge and partly by the bitterness that be had experienced during the exile to a remote island. From the latter would the fantastic narrative have resulted of the structure 'real-fantastic-real' or 'The upper world-this world-the upper world'. It may fairly be presumed that the fictional mode of dreaminess or sleepwalking, apparently most adoptable to SO-po was fit for the narratives in the hard times of Cho-son dynasty. The mode had been a stereotype in the in the early novels written in classical Chinese.
