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.

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.

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.

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.

戰略理論에 관한 硏究 : 國家政策을 수행하기 위한 戰略理論

宋澤龜 건국대학교 1977 論文集 Vol.5 No.1

A strategy, which has a close relation with politics and war, is used as means of achieving national goal and policy in persuit of a national benefit. A strategy may be classified into a national strategy (or grand strategy) and military strategy though the limits are not clear. It can be said that the grand strategy is a science of developing and employing elements of national military power including politics, economy, geography, scientific technology, social psychology, military potential, etc., in order to achieve a national goal auld policy, utilizing and controlling resources of a nation or those of between two nations, regardless of war time and peace time. A military strategy is defined as a course of military action designed for support of grand strategy established in accordance with a national policy to achieve a national goal. It is a strategem or science of crushing the will of enemy prior to war through buildillg-up of powerful military power and influence, or bringing in a victory in war. The ultimate purpose of military strategy lies in bringing in peace, that is, negotiation for peace from superior and advantageous position. Inorder to achieve a national goal, strategic activity has to be deployed based on basic policy and, if necessary, strategic victory has to be brough through war. When it is stated that a strategy is, therfore, an application of military tactics in one step lower, and that a military tactics is an application of grand strategy one step lower, and gland strategy, an application of a national policy in one step lower, these strategies form an order of step, yet with close relations to one another. Since strategy is a role as technique and means of crushing the enemy without entering into war, there are net many theories concerning its meaning ; from this point of view, good many tactics have to be devised applicable to the time and situation.

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.
