In terms of junior high school girls' growth patterns during early adolescence, unlike childhood when relatively balanced growth patterns are found and high school years in which the normal adult body type is almost reached, junior high school girls display imbalanced and rapid growth. In fact, diverse size changes by body part occur with a significant difference among individuals. Therefore, it has been difficult for junior high school students to select their exact size when buying a school uniform. This study attempted to develop winter blouse and skirt patterns reflecting the latest comfortable and active school uniform trends, using middle school girl avatars of various body shapes. Skirt and blouse pattern-drawing methods and margins differed. Based on such results, research prototypes were prepared. Then, virtual wear prospective drawings, clothing pressure, and appearance were assessed by body shape. Skirts were assessed with 22 factors while blouses were analyzed with 25 factors. Then, correlations between skirts and blouses were analyzed. According to the analysis, the reason why the dart & pleats position and margin were rated low was confirmed. In a virtual wear assessment on skirt patterns by body shape, a significant difference was found in all categories except for position of the hip circumference, margin of the hips, width of the skirt, and appropriateness of waist line position. The virtual wear assessment on the blouse patterns by body shape also revealed a significant difference in all categories but fit and shape pf the back part. In blouses, a significant difference was observed around shoulders and waist in type 1 and around the belly in type 2. On the contrary, for skirts, a significant difference was found around the hips and waists in type 1 and type 2. Therefore, these factors should be considered in making blouses and skirts. The above results suggested that skirt and blouse patterns should vary by body shape. It is anticipated that there should be further studies comparing brand-name school uniforms for high school girls and school uniforms by body shape.

The purpose of this study is to provide the improvement idea for an school uniform styling that better satisfies female high school students' changing demands, through evaluating images differences according to design variation in school uniforms. This study was carried out with a between-subject design by using the stimulant materials of school uniform design and image assessment scale. The stimulant materials used for this study were 27 designs with blazer/skirt ensemble and 21 designs with vest/skirt ensemble. The survey materials were collected through a questionnaire from a total of 192 female high school students living in Gyeongsangnam-do. As a result of analyses on a image of blazer/skirt ensembles, 4 factors were extracted such as neatness, uniqueness, activeness, and attractiveness. Blazer was the only variables that exerted significant effects on neatness, uniqueness, and attractiveness. As a result of analyses on a image of vest/skirt ensembles, 4 factors were extracted such as attractiveness, neatness, uniqueness, and activeness. Skirt was the only variables that exerted significant effects on attractiveness, neatness, and uniqueness. Neat image was perceived to be high in ensembles of standard blazer/standard collar/horizontal-seam skirt, standard vest/skirt with horizontal color combination, and buttons-down vest/horizontal-seam skirt. Unique image was perceived to be high in ensembles of blazer with bindings/standard collar/solid skirt, and vest with pockets/skirt with vertical bindings. Also, active image was perceived to be high in ensembles of vest with pockets/skirt with vertical bindings, and buttons-down vest/skirt with vertical bindings. Attractive image was perceived to be high in ensembles of blazer with bindings/peaked lapel/skirt with vertical bindings, and standard vest/horizontal-seam skirt. In conclusion, this study reveals that different items and pieces of school uniforms can be combined in many different ways to create quite diverse looks. Thus, this study provides important basic data for research on teenagers' fashion and clothing.

The purpose of this study was to investigate the wearing sensation and satisfaction of high school girls winter uniform' jacket. The subject participated in the study were 599 high school girls attending four different schools. The fabrics were divided into two parts of stretch and non-stretch woven fabrics. The results were as follows: 1. The high school girls showed body image distortion that she recognized herself as fatter than her real body type. Especially, this was severe in the slim body type. 2. In the aspect of the satisfaction for uniforms' jacket made with stretch fabric and non-stretch woven fabric. the elastic fabric was more satisfied than the non-stretch one because its width and length was shorter and fitter than non-stretch one. 3. When they wore the school uniform jacket, the wearing sensation of one made with stretch and non-stretch woven fabrics showed significant differences in arms hole when raising hands, front bust when carrying backpack on their back, backs while studying at desks, the upper arms and the elbows. 4. As for the alteration of school uniform jacket, the non-stretch woven fabric was appeared to be altered more than the stretch one.

We shall propose several estimators for the scale parameter in the uniform distribution when the parameter is functions of a known exposure level, and obtain expectations and variances for their proposed estimators. And we shall compare numerically relative efficiencies for proposed estimators of the scale parameter in the small sample sizes.

Adolescence is a transitional stage of physical development which occurs during the period from puberty to adulthood. Going through this period, various parts of an adolescent's body grow at different rates, leading to different body shapes and proportions when compared to adults. Therefore, this study aimed to investigate the body sizes and shapes of junior high school boys from ages 13-15 based on body measurement items that are used as the basis for school uniform designs including jackets, shirts, and pants. For this, the study sought the basic data needed to develop body shapes and school uniform patterns for junior high school boys using the data from the 6th Size Korea Survey (2010). Specifically, it provided basic data for the development of school uniform patterns that fit well through the classification of bodies into particular types. After extracting body shape componen a cluster analysis using ANOVA was performed. According to the factor analysis conducted to determine body shape components, 5 factors were obtained as follows: Factor 1: bulk and horizontal size, Factor 2: body height and length, Factor 3: shoulder shape and length, Factor 4: characteristics of horizontal size, Factor 5: shape of the upper body with a variance of 82.62%. To classify junior high school boys' body shape was determined using various characteristics, and a cluster analysis was performed with the variables obtained by the factor analysis. For this, body shapes were classified into 3 different types: Type 1 accounted for 33.4%, with a total of 463 subjects. This type was a tall, long body individual with the smallest bulk and size. Type 2 accounted for 22.7%, with a total of 315 subjects. This type was large in bulk and horizontal size, but the lowest in height and length. Type 3 accounted for 43.9%, with a total of 610 subjects. This type was close to average in terms of horizontal size, length, and height. To develop well-fitting school uniforms for junior high school students, there should be further studies on changes in body shape and their associated causes. The study results will be available as basic data for comparing branded school uniform patterns for junior high school boys and developing school uniform patterns based on body shape, using 3D virtual clothing simulations.

본 논문은 동영상 프레임 간 선명도를 균일하게 유지하면서 블러를 제거하는 기법을 제안한다. 고정된 변수들을 이용하는 기존 기법들과 달리, 제안하는 동영상 디블러링 기법은 영상에 따라 디블러 변수들을 조절함으로써 선명도를 균일하게 만들어 준다. 먼저, 입력 프레임의 초기 블러 커널을 추정하고, 디컨볼루션을 수행한 뒤, 선명도를 측정한다. 그리고 균일한 선명도를 유지할 수 있도록 측정된 선명도에 기반하여 정규화 변수와 커널을 조절하고, 다시 디컨볼루션을 수행한다. 실험 결과를 통해 제안 기법이 상당히 균일한 선명도를 유지하면서 디블러링을 수행함을 확인할 수 있다.

In this paper, we derive analytical expressions for the exact pairwise error probability (PEP) of a space-time coded system operating over spatially correlated fast (constant over the duration of a symbol) and slow (constant over the length of a code word) fad­ing channels using a moment-generating function-based approach. We discuss two analytical techniques that can be used to evaluate the exact-PEPs (and therefore, approximate the average bit error probability (BEP)) in closed form. These analytical expressions are more realistic than previously published PEP expressions as they fully account for antenna spacing, antenna geometries (uniform linear array, uniform grid array, uniform circular array, etc.) and scattering models (uniform, Gaussian, Laplacian, Von-mises, etc.). Inclusion of spatial information in these expressions provides valuable insights into the physical factors determining the performance of a space-time code. Using these new PEP expressions, we investigate the effect of antenna spacing, antenna geometries and azimuth power distribution parameters (angle of arrival/departure and angular spread) on the performance of a four-state QPSK space-time trellis code proposed by Tarokh et al. for two transmit antennas.
