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.

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 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 objective of this study is to give basic materials for selection and improvement of contents of safety education, which is substantially helpful to elementary students, by analysis of contents of safety education in some subjects and assessment of the needs of elementary students for safety education. For this purpose, this study was analyzed the contents of safety education in five subjects for elementary school and conducted the survey of 883 students in some elementary schools in Seoul from April 7 to 22, 2000. The results were as follows; 1.As a result of analysis of the proportion of contents regarding safety-related education in some subjects, Physical Education occupied the highest proportion (14.09%), and that was followed by Practical Subject (9.55%) and Moral Education (9.34%). However, the proportions in Social Study and Natural Science were very low,1.85% and 1.31% each. In total lines of these five subjects, the numbers of line regarding safety education was contained by 5.78%. 2.Analyzing the proportion of domains of safety education in five textbooks, the Meaning of Safety and Basic Principles occupied the highest portion (29.5%), and that was followed by the Home Safety (24.0%), the Safety in School (17.1%), and the Play and leisure Safety (14.0%). The Coping with Accidents and First Aid, the Safety from Fire and Explosion, and the Traffic Safety occupied relatively low portion, 6.9%, 5.7%, and 2.8% each. 3.As a result of analysis of the proportion of the safety education domain in each subject, the Meaning of Safety and Basic Principles occupied the highest portion (23.6%) in Moral Education, the Home Safely (12.7%) in Practical Subject, and the Play and Leisure Safety (10.9%) in Physical Education. 4.Most of the participants in this survey experienced the Home Accidents (71.1%). And also, they experienced the Play and Leisure Accidents (57.9%), the Accidents in School (49.7%), the Traffic Accidents (45.3%), and the Fire and Explosion Accidents (24.7%) in order. 5.In the average proportion of the needs of participants for safety education in each domain, the Coping with Accidents and First Aid has the highest point (4.05). And, that was followed by the Home safety (3.79), the Safety from fire and Explosion (3.73), the Meaning of Safety and Basic Principles (3.65), the Play and Leisure Safety (3.50), the Safety in School (3.37), and the Traffic Safety (3.35). The average proportion of the needs for safety education of total domains was 3.66. 6.In the needs for safety education regarding the feature of participants, it showed higher scores in female students than male ones (p<0.001), in lower grader than higher grader (p<0.05), and in the students born to wealth than those born poor (p<0.05). Also, the children who recognize the necessity of safety education showed higher scores of the needs for safety education (p<0.001). And it also showed the same results of high score to the children whose parents did the safety education (p<0.001) and to the children and their parents who have the higher degree of practicing safety (p<0.001), and these differences were statistically significant. 7.In the extent of preference for methods of safety education, it showed high score to the Field learning, followed by the Audio-Visual Education, the Discussion, and the Instruction of teacher. In the extent of preference for subject regarding the contents of safety education by each domain, it showed high score to the subject of Safety for 4 domains - the Meaning of Safety and Basic Principles, the Traffic Safety, the Safety from Fire and Explosion, and the Coping with Accidents and First Aid. And also, they preferred Moral Education for 2 domains - the Home safety and the Safety in School, and Physical Education for a domain of the Play and Leisure Safety. 8.While 27 of 36 detail items was contained the content of safety education, the proportion of needs of participants for safety education showed more than average 3.00 score in 34 of 36 detail items. However, none of 9 detail items was included in five textbooks. Also, 2 detail items - the Coping with Disasters and the Safely from Poisoning - were included together 2 parts; One part had the higher ranked 7 items acquired by analysis of the needs, and the other had the higher ranked 7 items acquired by analysis of the contents. But, except those 2 items, none of items were matched with each part.

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.
