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.

미끄럼 바닥에서 안정성 유지를 위한 균형 전략과 평가방법

김택훈,윤두식 한국전문물리치료학회 2003 한국전문물리치료학회지 Vol.10 No.1

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.

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.

The concentration of free amino acids in urine of control groups and cancer patients were determined by reversed phase high performance liquid chromatography using pre-column derivatization with dansyl chloride and UV detection at 254 nm. Urine samples from the cancer patient of stomach. liver, gall bladder and pancreatic cancer showed a decrease of concentration in all amino acids except for methionine, isoleucine, glutamic acid and alanine as compared with the control groups. The concentration of alanine was most increased of all amino acids, whereas. that of lysine was most decreased. The decrease rate of essential amino acids was larger than that of nonessential amino acids. The concentration of essential amino acids compared with control groups in cancer patients decreased by 20-50%, whereas that of nonessential amino acids decreased by 15∼25%. The ratio of essential to nonessential amino acids (E/NE ratio) in control groups and cancer patients was 0.669 and 0.435, respectively. The ratio in cancer patients compared with control groups was decreased by 34.98%.

Dual phase steel의 衝擊破壞特性에 關한 硏究

吳澤烈 慶熙大學校 1982 論文集 Vol.11 No.-

In this report strength, ductility, formability, energy absorption and deformed angle of dual phage being accompanied martensite volume fraction under the dynamic Impact bending load, is present. The reciprocal relations of thess factor which are studied in connection with variation impact velocity are as follows. (1) Impact maximum load is increased linearly in proportion to Martensite volume fraction increase rate. (2) Imapat maximum load is rapidly increased until fraction on the other hand, is slowly increased after fraction. (3) Loading time is nearly decreased linearly because ferrite volume decrease rate is constant. (4) Due to ferrite volume, energy absorption is decreased in proportion to martensite volume increase rate. (5) Reformed angle condition is similar until impact velocity reach 2.71 m/sec.

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.
