  • 적합성 시험(conformance test)은 통신 프로토콜 제품에 대해 그 제품이 프로토콜 표준에 따라 올바르게 구현되었는지를 검증하는 것이다. 그러므로 적합성 시험은 구현제품의 기능과 그 기능의 동작 행위가 프로토콜 표준에서 기술된 요구사항을 만족하는지를 조사하는 것을 요구하며 이를 시험규격으로 표현한다. 이때 프로토콜의 동작행위에 대한 시험 시나리오는 적합성 시험규격의 핵심을 이루는 것으로 시험을 기술하기 위한 국제표준 언어인 TTCN(Tree and Tabular Combined Notation)으로 기술한다. 본 논문에서는 적합성 시험 및 TTCN에 대하여 살펴보았다.

  • This study investigates the problems of fitness and motion suitability for Korean female military winter jackets (inner and outer) and provides data for new pattern development. We analyzed fitness and motion suitability by a questionnaire survey with 39 Korean female soldiers and a wearing evaluation with 8 subjects of the female soldeier's center size. The results of the study are as follows. 1. In the survey result on the fitness with female soldiers, fit of collar showed a score lower than 3.0 for the inner jacket and front interscye breadth, chest circumference, collar height on the outer jacket. The result on the motion suitability showed that both the inner jacket and the outer jacket were above 3.0 (moderate), indicating that the dissatisfactory factors were not large. 2. The wearing evaluation results with the subjects of central army female size, discomfort factor derived the chest circumference, neck circumference, item of the hem circumference and collar height on the outer jacket. This study is meaningful in evaluating the current military winter jacket of female soldiers and it is expected to be used as a basic data for future pattern improvement of military winter jacket for female soldiers.

  • We researched the comfort degree of 8 bodily parts while high school students carry out 9 different motions common to them. We observed high school students to study active effection when they are wearing Saenghwal Hanboks as a school uniform. As a result of this study, the highest degrees of comfort were recorded at standing position, walking, and upright sitting position with one's waist keeping 90 degree. On the other hand, the lowest degrees of comfort were experienced when they bend forward 45 degree and 90 degree each, and also when arms were folded across the chest. Furthermore, students reported that their buttocks, waist, and knees were comfortable during observation period, but that their backs, shoulders, and arm hole were uncomfortable throughout. In general, girls felt more comfortable than boys did, while they were wearing Saenghwal Hanbok as a school uniform.

  • The purpose of this study was to analyze the effect of the shape and attached position of E-textile-based stretchable sensors on motion-sensing performance and to investigate the requirements for the optimal structure of clothes for sensing limb motions. An experimental garment was prepared with different sensor shapes, and attachment positions. A child subject, wearing the experimental garment, performed arm and leg bending and extension motions at $60^{\circ}$, $90^{\circ}$ and $120^{\circ}$ motion angles, at a rate of 60 deg/sec. The changes in voltage triggered by the stretching and contracting of the fabric-sensor were measured, and an acceleration sensor was utilized to verify that the experimental motions were correctly performed. Dummy arms and legs of a child were manufactured to perform an identical test, in order to compare the dummy results with the actual human body experiment results. The analysis showed that the reproducibility and reliability of the rectangular sensor, showing uniform and stable were higher than those of the boat-shaped sensor, in both the dummy and the human body experiments. The attachment position of the sensor was more reproducible and reliable when placed on 4 cm below the elbow and knee joints in the dummy test, when placed in the joints of the elbow and knee, in children experiment. The appropriate shapes and attached positions of the sensor for sensing the motions were analyzed, and the results proved that motion-sensing of the human body is possible by utilizing flexible fabric-sensors integrated into clothes.

  • The purpose of this research is to suggest a new way to approach measuring the waist line of slacks. The pattern formulated enables a construction method that optimizes motion. The method is based on the measurement on the length change of the body surface line. The research reveals: 1. The analysis of expansion and contraction by area showed that G8 markedly shrunk, whilst G15 maximally stretched during M4 motion. 2. The areas that stretched during M2 motion were, in order of size: G10, G17, G16, and G8. Conversely, the areas that shrunk are, in order, G9, G11, and G18. The areas that stretched during M3 motion were G10, G17, G16, G12, and G15; the areas that shrunk were G9, G11, G18, and G8. 3. In constructing the slacks pattern to allow for appropriate movement, we calculated the length between the knee and back of the waist, point (y), using Pythagoras’theorem and trigonometry. The equation was y = 1.005x. 4. In the two pattern N method and L method, y is equal or less than x, but for our research pattern, y was larger than x

  • This study investigates the problems of fitness and motion suitability for Korean male military winter jackets (inner and outer) and provides data for new pattern development. We analyzed fitness and motion suitability by a questionnaire survey with 140 Korean male soldiers and a wearing evaluation with 7 subjects of central army male size. A survey of male soldiers indicated that the fitness and motion suitability satisfaction was over 3.0 (Likert scale) for both inner and outer jackets. There were opinions that the sleeve length was short for the inner jacket and the waist girth and hem girth was slightly large for the outer jacket. In the wearing evaluation results with subjects of central army male size, fitness of total length, sleeve length and collar height showed a score lower than 3.0 for the inner jacket and collar height on the outer jacket. The motion suitability result showed a low score (1.0-2.0) in an arm raising motion for the inner jacket and 2.0-3.0 at neck motion in the outer jacket. In conclusion, there is more dissatisfaction in inner jackets than outer jackets. For the inner jacket, sleeve is short, sleeve hem is narrow, collar height is a little high and the sleeve creeps up during arm motion. The waist girth and hem girth was slightly large and collar height was a little high for the outer jacket.

  • 전기기기는 통상 사용 후 고온부로 인해 회로적 과부하, 부품 고장 및 절연 파괴 등 어떠한 위험요서에 노출되어서는 안 된다. 또한 통상온도 상승 시험 후 감전 및 상해 대한 추가 시험이 반드시 뒤 따르게 되어 있다. 따라서 전기기기의 안전성을 판단하기 위해서 통상온도 상승 시험은 기본 사항이며, 필수적이라 할 수 있다. 본고에서는 전기용품안전기준 K60335-1의 제1부 규격과 개별 규격을 근거로하여, 통상 상태 즉 정상 상태 일 때 일반적인 온도 상승 시험장법 및 적합성에 대해서 설명한다. 또한 각 전기기기별로 온도 시험을 위해서 설치 조건, 동작 시간 및 적합성에 대해서 제시하고자 한다.

  • Based on the qualitative analysis, 4 factors of dance giftedness were operationally defined and test items were initially developed accordingly. The preliminary test data obtained from 206 dancers was analyzed, using item analysis and a series of reliability analyses. In order to dancer the construct validity, four exploratory factor analyses were conducted for 54 items, resulting in 20 items of 4 factors; physique, dance attitude Expressiveness and creativity, movement ability. A confirmatory factor analysis conducted for 292 dancers to test the goodness-of-fit of 4 factor model revealed a satisfactory level of $x^2$, Q, root mean square residual(RMR), goodness of fit index(GFI), Tucker-Lewis index(TLI), comparative fit index(CFI), root mean square error of approximation(RMSEA). The concurrent and cross validity indices proved the validity of 20 items of 4 factors.
