Purpose: This study analyzed the immediate effects of intra-abdominal pressure with visual feedback on the muscle activation of the upper trapezius and sternomastoid during natural inspiration and forced inspiration in individuals with costal respiration. Methods: The eighteen individuals with upper costal breathing pattern participated in this study. Surface electromyography was used to analyze the muscle activity of the upper trapezius and sternomastoid during natural inspiration and forced inspiration before and after intra-abdominal pressure. Results: A significant difference in muscle activation was observed with the muscle type, inspiration type, and test session (p<0.05). The muscle activities of the sternomastoid and upper trapezius decreased significantly during forced inspiration after intra-abdominal pressure training (p<0.05). On the other hand, there was no significant difference during natural inspiration in both muscles (p>0.05). A comparison of the difference between the pre-test and post-test during forced inspiration revealed the upper trapezius to be significantly larger than the sternomastoid (p<0.05). No significant difference was noted during natural inspiration (p>0.05). Conclusion: The intra-abdominal pressure has positive effects on correcting the breathing patterns in individuals with costal respiration.

Most stochastic taggers can not resolve some morphological ambiguities that can be resolved only by referring to lexical contexts because they use only contextual probabilities based ontag n-grams and lexical probabilities. Existing lexical rules are effective for resolving such ambiguitiesbecause they can refer to lexical contexts. However, they have two limitations. One is that humanexperts tend to make erroneous rules because they are deterministic rules. Another is that it is hardand time-consuming to acquire rules because they should be manually acquired. In this paper, wepropose context-dependent lexical rules, which are lexical rules based on the statistics of a taggedcorpus, and an ambiguity-driven teaming method, which is the method of automatically acquiring theproposed rules from a tagged corpus. By using the proposed rules, the proposed tagger can partiallyannotate an unseen corpus with high accuracy because it is a kind of memorizing tagger that canannotate a training corpus with 100% accuracy. So, the proposed tagger is useful to improve theaccuracy of a stochastic tagger. And also, it is effectively used for detecting and correcting taggingerrors in a manually tagged corpus. Moreover, the experimental results show that the proposed methodis also effective for English part-of-speech tagging.

The purpose of this study is to define concept and characteristics of "Unphenomenon", the design concept conceived by Shiro Kuramata who is a world renowned Japanese interior designer and to explore how his ideas were materialized in his works. This study 1) examines his experience during his childhood reflected in his essay The scenery of the Unphenomenon' and training in Kuwazawa Design Institute that made Shiro Kuramata a true interior designer, and also considers how his design philosophy had been built up and realized under the unique social situation at the time. 2) defines the concept and characteristics of "Unphenomenon" as substance of his design philosophy by surveying remarks in his books and comments made by people around him in press interviews. 3) concludes his own design method and uniqueness by analyzing his works based on them. As a result, the study has founded that 1) transparency as recognitive realization of existence and non-existence: non-existence of physical property, connotation, ambiguity 2) expression of uncommonness by correcting and reinterpreting common prejudices: flotation, distortion of scale and shape 3) realization of insubstantiality by removing and replacing material and shape: replacement into light, removal of the structure, multiple layers of meaning.

Purpose: There are several surgical methods for correcting a velopharyngeal insufficiency (VPI) but in some cases, it is not possible to achieve complete recovery of the velopharyngeal function. This paper introduces a new therapy for treating hypernasality without further surgery using continuous positive airway pressure (CPAP). Methods: CPAP therapy was applied to seven VPI patients for eight weeks from April of 2007 to September of 2009. All patients underwent palatoplasty for the cleft palate and six patients underwent palatal lengthening for VPI before CPAP therapy. A speech pathologist performed an auditory perceptual evaluation to evaluate the improvement in hypernasality after 8-week CPAP therapy. Results: Six patients showed an improvement in hypernasality after CPAP therapy according to the auditory perceptual evaluation. One patient with severe hypernasality responded to the early part of therapy but the hypernasality did not improve after therapy. Conclusion: CPAP therapy might be effective in reducing the hypernasality in patients with VPI by providing resistance training to strengthen the velopharyngeal closure muscles. In particular, CPAP therapy could be more effective for patients who show mild to moderate hypernasality after surgery.

Nowdays the prison is the only correctional for juvenile delinquents not to be the second offenders in Korea. Originally the correctional education aims to let criminals go back to the society as a decent citizen after correcting them and prevent them from comminitting crimes repeatedly. Being considered to increase the second offenders in juvenile delinquency, the purpose of this study is to investigate the actual condition and problems of juvenile correctional education in Korea and to find out the solution of problems. First of all, this study examines the actual condition of the juvenile delinquency in Korea. The number of juvenile crimes has been increased from 1985 to 1995. In 1997, the current education in correctinal institutions for juvenile delinquents is inferior to that of developed countries. On the basis of this investigation, improvement plans which will be fit for the circumstances in Korea are suggested. The conclusion of this study are summarized as follows 1. Correctional institutions will be improved to accommodate the proper number of convicts. 2. Correctional officers should be qualified proffessinals who can achieve the aim of correctional education successfully. 3. In order to cultivate he social adaptability of convicts, the expansion of open prison is needed. 4. It is neccessary to classify convicts by means of moderized and scientific methods. 5. Correctinal education consist of various practical courses on jobs, After complenting these vocatinal training, the convict can obtain certificates. 6. The government has to has to plan policies that the released convicts can get jobs for living. 7. Owing to keeping prisons sanitary, it is very helpful for convicts to have thebelief that they are not abandoned by the member of their society. 8. Convicts are given opportunities to participate religious activities by their free-will. If above improvement plans are sufficiently accomplished, correctinal education will obtain good results, It is also effective to minimize the repetition of offence by ex-convicts.

Compressional sound velocities of shelf sediments in the South Sea of Korea, were measured in situ and in the laboratory for six cores. In situ sound velocity was measured using the Acoustic Lance (frequency of 7.5-15 kHz), while laboratory velocity was measured by the pulse transmission technique (frequency of 1MHz). Physical properties were relatively uniform with sediment depth, suggesting little effect of sediment compaction and/or consolidation. Average in situ velocity at each core site ranged from 1,457 to 1,488 m/s, which was less than the laboratory velocity of 1,503 and 1,604m/s. In muddy sediments the laboratory velocity was 39-47 m/s higher than in situ velocity. In sandy sediments, the difference was greater by an average of 116 m/s. Although the velocity data were corrected by the velocity ratio method based on bottom water temperature, the laboratory velocity was still higher than the in situ velocity (11-21 m/s in muddy sediments and 91 m/s in sandy sediments). This discrepancy may be caused by sediment disturbance during core collection and/or by the pressure of Acoustic Lance insertion, but it was most likely due to the frequency difference between in situ and laboratory measurement systems. Thus, when correcting laboratory velocity to in situ velocity, it is important to consider both temperature and frequency.

Purpose: The purpose of this study was to investigate the effects of home exercise program and exercise program of round shoulder adjustments on the level of trapezius muscle activity and attention capacity for middle school students. Method: The participants in this study were composed of 21 middle school students. We made the students lie on the floor in prone position, then measured the height of their acromion from the floor. We chose participants for our study whose measurement values were over 2.5cm. We divided them into two groups, one is for the experimental group, and the other is for the control group. The experimental group exercised three days a week for 6 weeks, including home training, and the control group didn't exercise. We used EMG to measure the trapezius muscle's activity and used a Stroop test for the measurement of the students' attention capacity. Results: The results of our study are as follows. There was no significant difference between the experimental group and the control group. However, there was a significant difference within the experimental group when comparing pre and post training results for Trapezius muscle activity and attention capacity. Conclusion: We found that correcting round shoulder symptom increases the Trapezius muscle activity and students' attention capacity. Future experiments should investigate with systemical management. Also, we need to increase the frequency of the exercise and participants.

This study is aimed at investigating the compensatory education which was already implemented or is being implemented in the U.S.A. and Japan; and at studying the types of programs and their characteristics; and at sounding out the possibilities of the application of such programs in family and social conditions is Korea. In order to achieve the above mentioned objectives, the established items for the study are as follows: (1) Various types of early children's education (2) Programs of compensatory education for the disadvantaged Children (3) Head Start Program, Early Training Project and Montessori School (4) Integrated Preschool Programs (5) Day-Care Center for employed mothers We investigated the various compensatory education programs for the preschool children who are in economically, socially, culturally disadvantaged conditions. Head Start Programs were federally supported programs for preschool children and opened as summer programs in 1965 for the first time. The purpose of Head Start has been to give preschool children the kinds of experiences they need in preparation for school. The Head Start children were found to be significantly better prepared for school than the normal children. However, after six to eight months, their initial advantages had virtually. disappeared and then the simple problem with Head Start and other such programs was that little long-term good could be evidenced unless the high quality educational environment was maintained. Therefore, to solve this problem, three other programs were funded as part of the overall Head Start. These three programs are the Parent-Child Center, Home Start, and the Child and Family Resources Program. The Early Training Project for disadvantaged children was implemented by Klaus and Gray of Peabody College in 1962. The program was a field research study concerned with the development and testing over time of procedures for improving the educability of young children from low income homes. Its major concern was to study whether it was possible to offset the progressive retardation observed in the public schooling careers of children, living in deprived circumstances. Children, who were trained through the Early Training Project were superior to control groups in the test of IQ and vocabulary as well as linguistic abilities, and preparation for reading. This project showed the possibilities which could prevent preschool children from being disadvantaged socially, culturally and mentally. In 1907, Montessori School was established by Maria Montessori in Italy and her school program has been introduced at present to several countries in the world as one compensatory educations. She first began her experimental methods with retarded children, followed by disadvantaged children from the tenements of Rome. The Montessori approach futures a prepared environment and carefully designed, self-correcting materials. The Montessori curriculum presents tastes that feature sequence, order, and regularity, in addition to those that develop motor and sensory skills. She was interested in children's intellectual development and in developing good work habits. One of the latest developed programs for disadvantaged children is "Integrated Preschool Program" which has successfully integrated handicapped and nonhandicapped children. Several studies have showed that handicapped children in integrated school environments are accepted by and interact with their nonhandicapped peers. In fact, this program provides a number of potential, and perhaps opportunities for nonhandicapped children to serve as valuable resources in fostering the development of their handicapped peers. Next we turn to Japanese programs which are divided into two different types. One is Day-Care Center which was established by Child Welfare Law and the other is kindergarten organized by School Education Law. The kindergarten opened in 1876 and it has been part of school systems since 1947 by the implementation of education law, and the Day-Care Center which started in 1890 for the employed mothers. was changed into Day-Nursery by the enactment of child welfare law in 1947. The laws and operational regulations for the Day-Nursery were set up and were put in effect by the establishment standard acts of children welfare facilities, and the Day-Nursery has been operated in various types by the increasing demand, chiefly because of the socio-economical changes of family structures in both urban and suburban areas. Nursery education for physically and mentally disadvantaged children is for those who are blind, deaf and dumb, mentally retarded; physically disadvantaged by accidents or diseases. Montessori education in Japan was started in 1968 and many research groups for studying Montessori were organized. In 1977, Montessori remedial education society was also organized in which they started a number of studies; a study for developing materials; in-service training for the remedial education; and seminars and lectures, etc It is strongly suggested that we study the early educations that are being implemented in Japan and a variety of compensatory educations that were already implemented in the U.S.A. and modify them for the organization of our own model and properly accommodate them to our social needs.
