A new coinage which calls a modern was appeared variously by values, taste, feature of lifestyle and the meaning of a new coinage has influence in the change of lifestyle. Particularly a popular star is a person who situates in the center of a new coinage, his role, behavior, and appearance have great influence in the birth of a new coinage. He is a fashion leader as well as the object of fashion imitation to the new generation being sensitive for fashion. As his fashion is appeared with important fashion icon in fashion market, fashion companies have developed actively star marketing marking him as an advertising model. Therefore, because the fashion trends of a popular star introduce season's fashion trends and can be important factor forecasting fashion behavior of consumer, this study aims at analysis for fashion trends of a popular star including a public entertainer. The dates of this study were collected by TV drama, internet, and magazines, etc. The fashion trends were divided into feminine fashion trend, sexy fashion trend, tomboy fashion trend, and retro fashion trend. Feminine fashion trend was based on feminity but it was classified in masculine look, simple look, chic look, and natural & romantic look according to the standard of a transformation of feminine image. Sexy fashion trend was divided into two sexy images according to the method wrapping oneself in a dress and the method exposing a specific body part. Tomboy fashion trend could be the immature boyish style which concealed bust or hip or pelvis symbolizing feminity. Retro fashion trend could be style being based on 1980's style and Y line. Fashion items as leggings, baby doll dress, tunic style, dot pattern, garsonne look were come into fashion.

Today, natural ventilation systems are widely applied in multi-family housing. However, studies using the wind data trend line of the blower door test are insufficient. Purpose: Through this study, we will propose a computational method about ventilation performance of natural ventilation systems by conducting blower door test. Method: First, we sealed the gaps between the main systems including the natural ventilation system and conducted the blower door test. Next, the natural ventilation system was opened, the blower door test was conducted, and the difference in air flow rate between when closed and when opened was checked. Blower door test was carried out with a pressure difference of 50 Pa. Result: Therefore, the ventilation performance of the natural ventilation system was checked by drawing a trend line using the data to calculate the air flow rate at 2 Pa of the natural ventilation equipment standard pressure difference.

Objective: The aims of this study were to assess the direction and degree of lip-line cant in Korean adult orthodontic patients and to identify the effects of sex and age on changes in the cant severity. Methods: In this cross-sectional retrospective study, lip-line cant was measured in the frontal photographs of 585 Korean patients (92 men and 493 women) aged 18-48 years. The outcome variables (direction and degree of lip-line cant) were assessed in terms of predictor variables (sex, age, sagittal skeletal relationship, and menton deviation angle). Results: The direction of lip-line cant did not differ according to sex, age, or skeletal classification. Patients had $1.6^{\circ}$ of lip-line cant on average before orthodontic treatment. Middle-aged adults displayed a significant trend toward a lower degree of lip-line cant compared to younger adults (p < 0.01). Multiple linear regression analysis showed that the degree of lip-line cant was weakly negatively correlated with age (p < 0.001). Conclusions: While the direction of lip-line cant did not differ according to the parameters explored here, the degree of cant was correlated with age in adults, independent of menton deviation. Specifically, middle-aged adults tended to display significantly lower degrees of lip-line cant than did younger adults.

The recent fashion trend of knit wear is now changing to the various fibrous color combination which emphasizes the plain texture. It supports the human body curvature which is influenced by the slim style of woven wear. In this research work, the general characteristics and knit wear fashion trend are studied. The metallic fiber and fancy yarn are used widely as fiber materials for knit in nowadays. However, the light and functional materials are preferred. The general characteristics of knit which gives the feeling of light and warm are still prevailing using pure wool, kid mohair, and mixed wool with polyester. In order to provide the soft touch feeling, smoothness of fine fiber, and feeling of sponge, several kinds of finishing techniques such as bulky, felting, bonding, and quilting process are usually adopted. The knit wear fashion trend is mainly consisted of the basic design items, and it gives the feeling of luxurious and elegance. The more youthful feeling is adapted for the general style of knit wear of the certain target age. The woven wear trend such as season color, line and pattern are applied in knit wear trend in recent days.

Long-slit spectra, covering the wavelength range 4050~5150$\AA$, have been used to investigate the radial behavior of absorption line features (G4300, Fe4383, Ca4455, Fe4531, Fe4668, and H$\beta$) along the major and minor axes of the bulge of M104. The heliocentric recession velocity of M104 has been derived as 1260$\pm$190${kms}^{-1}$. The strength of a number of metal absorption lines is decreasing with increasing radius, and the minor axis shows much steeper radial line gradients than the major axis. Line index of H$\beta$ has an opposite trend to other metal lines, i.e., increasing outward. The results in this paper imply that the properties of absorption line index distribution in M104 bulge have in many aspects similar trends to those of elliptical galaxies.

전력선통신 위해방지 기술기준은 전력선통신 장치가 인체나 다른 설비에 위해를 주지 않도록 준수해야 할 기술적 사항을 규정하고 있다. 전력선통신 위해방지 기술기준은 내용면에서 선로설비 설치에 대한 기술기준과 통합 운영하는 것이 효율적이다. 본 논문에서는 국내 전력선통신의 기술적 배경과 기술기준 개편방향에 대해 같이 논하기로 한다.

The paper considers the relation between on-line monitoring and diagnostics on the one hand and high-voltage (HV) withstand and partial discharge (PD) on-site testing on the other. HV testing supplies the basic data (fingerprints) for diagnostics. In case of warnings by on-line diagnostic systems, off-line withstand and PD testing delivers the best possible information about defects and enables the classification of the risk. Because alternating voltage (AC) is the most important test voltage, the AC generation on site is considered. Frequency tuned resonant (ACRF) test systems are best adapted to on-site conditions. They can be simply combined with PD measuring equipment. The available ACRF test systems and their application to electric power equipment -from cable systems to power transformers - is introduced.

The automation and Cell-Line of manufacturing process are going to be new trend in the industry spot. But workers bodily burden by manual labour is still doing repeatedly at many processes. It is appearing to workers bodily burden (Shoulder, waist, hand, wrist, leg) with repeating works at assembly line which is from the static working space. The analysis with 6 Sigma Tool at specific standard assembly line improve the point at issue for unsuitable items and analyzed objects. Physical pain of worker is solved by the improvement action for the factor of 7 items with the result of analysis. It was known to be improved by solving of workers burden related to the change of 6 Sigma level from 2.16 to 4.1 at assembly line.

이 연구에서는 측정의 본성에 대한 견해에 따라 중학생이 구성한 일상 및 과학적 맥락의 그래프에서 나타나는 차이를 조사하였다. 중학교 3학년 학생 151명이 연구에 참여하였다. 일상 및 과학적 맥락만 다른 상황에서 비례, 반비례, 비례하게 증가하다 일정해지는 형태의 그래프를 구성할 수 있도록 유사한 측정값을 갖는 자료를 각각 제시한 후, 학생들이 구성한 그래프를 추세선 구성(추세선의 유형, 내·외삽), 축 변수 설정, 축 눈금 표기와 점 찍기 측면에서 분석하였다. 연구 결과, 집합 패러다임의 학생들은 반비례 그래프의 추세선을 곡선형으로, 점 패러다임의 학생들은 꺾은선형으로 구성하는 경향이 있었다. 내·외삽의 경우, 과학적 맥락의 그래프에서 집합 패러다임의 학생들은 점 패러다임의 학생들보다 내·외삽을 더 잘 수행하는 경향이 있었다. 이때 집합 패러다임의 학생들은 일상 및 과학적 맥락과 무관하게 내·외삽을 잘 수행하였으나 점 패러다임의 학생들은 일상적 맥락보다 과학적 맥락에서 내삽만 수행한 비율이 높았다. 축 변수 설정, 축 눈금 표기, 점 찍기 요소는 패러다임 유형에 따른 통계적으로 유의미한 차이가 없었다. 연구 결과를 바탕으로 중학생의 그래프 구성 능력 함양을 위한 교육적 시사점을 논의하였다.

선 그래프는 막대그래프와 달리 각 변인들의 변화에 기인한 경향을 보여준다. 따라서 선 그래프로부터 경향을 파악할 수 있는지의 여부는 중요하다. 본 연구의 목적은 선 그래프 도식을 지닌 학생들이 선 그래프를 읽고 해석할 때 선 그래프 도식을 지니지 못한 학생들과 비교하여 어떠한 사고과정을 거치는지 파악하는 것이다. 발성사고를 통하여 고등학생틀의 선 그래프 이해 수준과 선 그래프 유형에 따라 선 그래프를 읽는 사고 과정의 특징을 분석한 결과, 동일하게 주어진 시간 동안에 상위 그룹에 해당하는 학생들은 하위 그룹에 속하는 학생들보다 더 많은 문장을 발성사고하였으며, 하위 그룹의 학생들과 달리 적응단계에서 선 그래프의 유형, 경향, 라벨 등을 파악하는데 오랜 시간을 사용하였다. 또한 상위그룹의 학생들은 하위그룹의 학생들보다 초인지적인 문장을 발성사고하는 경우가 더 많았다. 선 그래프 도식을 지닌 학생들과 단순히 일반적인 그래프 도식을 지닌 학생들을 구별하고 그에 따라 정보를 전달하는 방식을 달리하는 융통성이 필요하다.
