This study was performed to confirm the actual temperature rise on the surface of Buchanan plugger by evaluating the temperature rise on the surface of it, the peak temperature of pluggers of various size using thermocouple. The heat carrier system 'System B Heatsource' (Model 1005, Analytic Technologies, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200 which Dr. Buchanan's "Continuous wave of condensation" technique recommended on digital display and the power level on it was set to 10. The touch mode was used. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 ㎜ increments from the tip to the 4 ㎜ length of shank. Each thermocouple was secured with cyanoacrylate adhesive and orthodontic resin block. The two wire leads of each thermocouple were connected to the appropriate channels of Data Logger. This was configured to simultaneously record input from the five thermocouples. The heat control spring was touched for 1, 2, 3, 4 and 5 seconds, and the temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01. Ten trials was determined for each plugger. The average of temperature rise and standard deviation was calculated for each size of plugger. The data were statistically analyzed by one-way ANOVA to determine their significance. The results as follows. 1. The position at which the temperature peaked was approximately at 1∼2㎜ far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F type and followed by, in descending order, FM type, M type. ML type showed the lowest peak temperature (p<0.01). This results suggest that the actual temperature on the surface of the pluggers does not correlate well with the temperature set on digital display. Heat concentrates around the tip. The larger plugger reveals lower temperature rise relatively.

국민학교 어린이들의 자세의 諸特性을 分析하여 學校現場에서의 자세교육의 지도자료를 구하는데 연구 목적이 있다. 서울, 경기지방의 남녀 어린이 240명에 대하여 척주 만곡도, 下肢의 상태 등을 계측하여 分析檢討한 結果를 다음과 같이 要約할 수 있다. (1) 연구대상자의 신체 형태의 특징은 細長型인데, 약 28%의 어린이는 전에 병을 앓은 경험이 있고, 50∼60%의 영양 불량아가 있다. (2) 자세에 미치는 환경 요인은 不實한 傾向이 있지만 자세 지도나 자세에 대한 관심도는 비교적 높다. (3) 立位자세의 표준 前傾度는 남자 4˚∼+5˚, 여자 -3˚∼+3˚이다. (4) 흉추부의 표준 만곡도는 남자 3˚∼12˚, 여자 4˚∼12˚이다. (5) 표준 상배 후만각은 남자 155˚∼168˚, 여자 152˚∼166˚이고, 표준 요부전막각은 남녀 모두 152˚∼168˚이다. (6) o脚은 전체 어린이의 7%이고 x脚은 3%를 차지하고 있다. The purpose of this study was to obtain the materials on the posture education at school. The subjects chosen for this study were 240 children from the first to the sixth grades at the elementary schools located in Seoul and Kyong-Gi Province. The children were interviewed each to examine the posture structure, were measured the degrees of vertebrae curvatures and the structure of the lower limbs by the Cureton's conformatuer to find the characteristics of the posture. The results were: (1) The children were near to the type of ectomorph posture. About 28% of the children had previously suffered the serious diseases. The children of unbalanced diet were from 50% to 60% of the total number. (2) 45% of the children used the desks and chairs when they study, and 70% of them had their desks and chairs unfit to their body structures. (3) Under these unfavorable circumstances, the children showed, however, the higher enthusiasm for the posture education which is encouraging. (4) The average Angle ∠α of forward curvature in standing position was about -4˚∼+5˚ among boys and -3˚∼43˚ among girls. (5) The average angle ∠a' of verabrae curvature of the thoracic was 3˚∼12˚ among sboy and 4˚∼12˚ among girls. (6) The male with Kyphosis (hunch back) was about 155˚∼168˚, the female was 152˚∼166˚. The male and female with lordossis of lumber curvature was 152˚∼168˚. (7) The children of bowlegs (O type) and those of knock knees (x type) were 3% of the whole.
어패럴 CAD System의 활용화 방안 연구(Ⅰ) : Hip Block 의 개발
남윤자,이형숙,조영아 한국의류학회 1993 한국의류학회지 Vol.17 No.4
The Purpose of this study was to develop pattern drafting methods of the hip block and sleeve for female college students of 18 to 26 year-old. The study procedures and results were as follows 1. 313 female college students were measured, 17items were analyzed statisitcally. 2. New hip block and sleeve sloper were developed based on the result of the data analysis and fitting tests. 3. The sensory test was applied to evaluate the new hip block and sleeve sloper for female college student by comparing it with Japanese Bunka method sloper. According to statistical analysis of the result of 40items on the questionnaire, all the items showed significant difference(a∠=0.01) between the two, with the new pattern having higher scores. The new drafting method proved to be better fitted at all 40items, and to be comfortable.

This study aimsat the understanding of its real facts and how to organize them through the morphological and synthectical viewpoint to the objective-subjective, objective-genitive, and objective-dative among the objective-suffix appeared in the literature of DUSIUNHAE first and second edition. In the above case, the objective-suffix is unable to be interpreted as an object, for it does not mean the traditional one but is applied another functions. It shows lots of uncertainty and awkwardness through the language consciousness of modern Korean. But these seem to be un voidable situations appearing in the course of interpretation, for the most of literature data of the mediaeval Korean were interpreted the Chinese composition into Korean. (1) So far as it is possible for the object to be interpreted as the subjective meaning, it is followed by the condition to be a subordinate clause. This is the case of forming the double object through the subjective suffix in simple sentence is changed into the objective-suffix in complex sentence. (2) According to the case, how can the various appearance of object be interpreted? The interpreting methods of the first-object are pointed out to be related to the form of predicative and object which the predicative chooses. (3) In case that object in interpreted as a dative, objective suffixes attaching to the direct object and indirect on are not fixed firmly in their word order, especially in the word order of object appearing as a double-object. The objective-dative realized to the indirect object, therefore, is taken as a part of being topic. (4) To the abbreviation of object, all kinds of object, as a rule, is pointed out as a thing to be omitted in general usage, But, as it is known that their appearance and abbreviation are very irregular, it is impossible to regularize them, and the situations where they should be certainly realized are pointed out in this study.
