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.

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.

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.

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.

幼兒들의 數槪念發達에 관한 硏究

In this paper, it was intended for the children to develop their concepts of numbers in mathematics and to survey the features of their concepts of numbers. For this purpose, the objectives were the normal 69 kindergarden pupils and 494 pre-school children in Kyeongbuk area. And it was divided into 3 parts to find the concepts as follows: a) Calling the numbers in order b) Counting the materials c) Picking up the materials by number The basic abilities of the concepts were also surveyed for this purpose as follows: a) Equivalence in classifications b) Equivalence in numbers c) Conservation of numbers Here the results of this study were found by the method of proceeding parts of the concepts as follows: a) Children's abilities of calling and counting numbers were growing by their ages and developed by almost the same level. The abilities were able to be caught at the age of 4:3∼5, 5:6∼7,6:11∼20. b) Their abilities of picking up the materials by numbers were able to be caught at the ages of 4:3∼4,5:4∼5,6:8∼10and found to be undeveloped as compared with above two abilities. c) The city living children's concepts were a little more developed than those in the rural community and especially the abilities of calling and counting numbers differ city children from rural children by ther growing ages. d) Their concepts of semi-numbers were different in their circumstances but they were not strongly different. In kindergarten, they were developed quicker a year more than the other general children. e) Their equivalences in classification and number were almost same to both children and the age for this abilities seems to be at the age of 5. f) Their abilities of conservation of numbers were later than the other abilities. The age for this abilities are at the age of 6.

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.

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.
