Appearance matters in society today. Women want to feel good and look their best. They do make-up, wear garment and accessory for their good looking. Doing make-up, we have to know how we are look and to consider face shape. But it is difficult to recognize face shape. Because there is no standard face shape of adult women of quantitative analysis. The purpose of this study was to offer standard face shape of adult women in Korea. Furthermore, the study was to determine and differentiate face shape of each age group to set the basic data for the Korean beauty industry. In this study, photographs of 600 Korean women, age between $20{\sim}50's$, were indirectly measured in Venus face2D program. The measurements were analyzed by statistical methods. As a result of basic statistical data analysis, the average lengths of face were 196mm, lengths of forehead-hairline between eyebrows were 62mm, lengths of eyebrow between noses were 68mm, length of nose between chin were 66mm, and width of face were 150mm. By comparing to each age group's face using ANOVA, the statistically noticeable differences were found in measurements.

Advanced afterburner used in the most modernized gas turbine has new designing paradigm to cope with reinforced power density. The most distinct change is the designing trend to integrate fuel injectors and flame holder in order to manage higher temperature of inlet air. F414 and F110-GE-132 engine adopted this methodology and installed a variable nozzle utilizing CMC(Ceramic Matric Composite) material and active cooling of nozzle flap with ejector nozzle in order to enhance the life cycle of engine components and an economical aspect. These technological trends can be utilized for an advanced ramjet engine and combined cycle engine like TBCC.

Scott 결선 변압기는 3상전원에서 단상부하를 공급해야하는 계통에서 많이 사용되고 있다. 특히 전기철도가 이에 해당되며 국내에서는 전기철도의 화장으로 Scott변압기가 154kV급의 송전계통에 연계되어 설치 운전되고 있다. Scott변압기의 특성상 단상인 부하측 또는 3상인 전원측에서 사고 발생시 각상에 흐르는 불평형 사고전류의 예측이 어려워 관련기기의 선정과 각종 보호계전기의 정정이 쉽지 않았으며 과도현상 해석도 쉽지않았다. ATP(Alternative Transient Program)는 전력계통의 과도현상뿐만 아니라 단락 및 지락과 같은 정상상태 해석 및 고조파 분석도 가능하며 그래픽 유저 인터페이스를 위한 ATPDraw도 개발되어 데이터 입력과 사용법이 보다 간편하게 되었으며, 출력파형을 위한 PlotXY도 개발되어 계산결과를 다양한 형태의 그래프로 출력할 수 있게 되었다. 무엇보다도 User Group에 가입하면 무료로 모든 프로그램을 사용할수 있는 장점도 있다. 본고에서는 ATP를 사용하여 Scott변압기의 모델링과 이를 통한 단락 및 지락 사고 둥의 해석 사례를 소개하였다.

We investigated the morphological characteristics of the pearlescent pigment by using scanning electron microscope, energy dispersive X-ray spectrometry and thermal analyzer. The result is that the shape of pigment is platy polygonal form through observing the pearlescent pigment by the scanning electron microscope. The size of pigment is various and not formed in standardized size or shape. The pigment flakes were measured about from $30{\mu}m$ to $300{\mu}m$. The tip of the piece of pigment is pointed shape or angled. The result of observing them by the scanning electron microscope in magnifying high power is that the edge and the lateral face of them is an round form and the measurement of thickness is about $9{\mu}m$. As well using the high magnification scanning electron microscope, the surface of the pigment flake observed like rugged as coating with the $TiO_2$ element, the diameter of the coating particle is around 60 nm, then the coating particle consists of granular substance. Analysis of the configuration elements of pearlescent pigment using by the energy dispersive X-ray spectrometry is that O, Si, C, Na, Ca, Ti, Zn detected in the surface of pigment and its lateral face identifies similar components. In thermal analysis, there are no contained quantity differences between them in beginning from $100^{\circ}C$ to $800^{\circ}C$ showing thermal analysis, 1.1% out of contained quantity reduced at $115^{\circ}C$, 1.7% dropped at $416^{\circ}C$, and 1.9% decreased at $797^{\circ}C$.

The purpose of this study is to show dental hygienist's stable and comfortable attire during dental paitients treatment, and to enhance dental hygienist's image. 486 adult patients who visited local dental clinics or centers in three cities of Jeonbuk province, Jeonju, Iksan and Gunsan were surveyed by self developed questionnaire. The collected data were analyzed with frequency, percentage and chi-square test (${\chi}^2$-test), using SPSS program. The results of this study are as follows: 1. Respondents preferred two-piece skirt (39.1%), the face with whole make-up (45.9%). There were significant differences in gender (p<0.01). 2. 36.2% of respondents preferred pink-colored uniforms. 3. Respondents preferred sandal (44.2%), there were significant differences in age, gender (p<0.01, p<0.05). 4. In terms of indication or identification for dental hygienists, 60.7% of respondents preferred nameplate. There were significant differences in age (p<0.05). 5. 75.9% of respondents thought that favorite uniform and costumes that patients prefer could help them feel easy.

The purpose of this study is to suppose makeup design based on formative elements of facial image according to the facial image type of Korean women in their 20s. For this study, literature review were performed. Surveys were conducted twice for empirical research. The survey targeted 220 university students in their 20s. SPSS 12.0 statistics program was used to analyze the results, and T-test, ANOVA, Scheff$\acute{e}$ test. The results of the study are as follows. First, it was concluded that the effective structural formative elements are different according to the types of facial image. Second, by analyzing the differences in perceiving naked facial image and modified face shape image, modified skin color image, modified makeup color image of all types of facial image, it was found that the formative elements are different according to facial images, and that there are differences in the effectiveness of each factors.

visual cryptography is a simple method in which secret information can be directly decoded in human visual system without any cryptographic computations. This scheme is a kind of secret sharing scheme in which secret of image type is distributed to n random image(we call it share). When the secret image is distributed to n shares, the original pixel is expanded as much as the size of column in basis matrix. It causes the deterioration of contrast in docoded secret image. Therefore, many researches have performed to reduce the size of pixel expansion and to improve the contrast by overlapping the row in basis matrix for (k, n) visual cryptography. In addition, we show that the proposed method can construct the (k, n) visual cryptography with multiple contrasts depending on selecting k out of n slides in a group.

In this paper, we propose an improved method of state exploration called the extended circular exploration (ECE) for the efficiency of state exploration and the reduction of explosively growing state. The ECE does not need to explore all the reachable global states, and It can be applied to JV($\boxDr$$\geq$ 2) -party protocol with alternative routes, i.e., it is applicable to the protocol In which adaptiverouting mechanism can be performed. The ECE eliminates a restriction of topology of the conventional circular exploration(CE) by exploring only those global states which are reachable, provided that the participant processes of any group of transitions proceed at the same speed, and that they can be formed as a cycle. Thus the state space explored if not exhaustive. The algorithm presented can detect deadlock error and unspecified reception error It requires storage space and /or execution time much less than those of the conventional perturbation(CP) . It might be used for a solution of the N-process collision and the interference mechanism.

The reuse by using framework is proposed to improve productivity. It is a set of usable and expandable classes and their connectivity. But frameworks are described with programming languages, it is hard for developers to learn the collaborative patterns of a framework by reading it. Patterns are one approach to improving the documentation. But this should be redesigned to expand and redefine the framework. The necessity of the formal description of architecture information is being proposed to relate to programming language. This paper support the following points. First of all, it has been proposed the description of the needed elements when developing a framework using ADL. Secondly, the current development process has been refined to be suitable for developing the domain framework. Thirdly, it has been proposed the development of a application using a framework implemented by an architecture information described with ADL. Overalls, the main contents of this research is defining the ideas of a description and development of an architecture framework using ADL.
