The purpose of this study is to observe the meaning of Minimalism and the characteristics in modem fashion design. The Minimalism appeared in 1960's has affect on fashion design which are simple miniskirt or Courrage look of those days. It leads a fashion system to the simple style goes with the life style of modem persons although the characteristics are somewhat different the styles in 1960's with those of 1990's. Minimal style is not just simple style but abbriviate expression constrained at the minimum. The styles appeared to be an undecorated simple line which are a sleeveless onepiece, a simple suit with no pocket and no collar and narrow shoulder. Colors are monochrome coordination and pursue a simplicity which is monotone variation. Patterns also appeared to be a geometric or abstract pattern for example check and stripe, which intend to minimum expression. Matirials are hightech glossy coating textures which have a futuristic image. In conclusion, the Minimalism in 1990's appeared to be a post-minimalism associated with postmodernism and a hightech-minimal under the technology development.

A lot of data, particularly in the medical field, contain variables that have a measurement error such as blood pressure and body mass index. On the other hand, recently smoothing methods are often used to solve a complex scientific problem. In this paper, we study a Bayesian curve-fitting under functional measurement error model. Especially, we extend our previous model by incorporating covariates free of measurement error. In this paper, we consider penalized splines for non-linear pattern. We employ a hierarchical Bayesian framework based on Markov Chain Monte Carlo methodology for fitting the model and estimating parameters. For application we use the data from the fifth wave (2012) of the Korea National Health and Nutrition Examination Survey data, a national population-based data. To examine the convergence of MCMC sampling, potential scale reduction factors are used and we also confirm a model selection criteria to check the performance.

The characteristics of a disk-loaded cylindrical dipole (DLCD) antenna that determine its performance are analyzed by using the method of moments. The current integral equation that is considered with extended boundary condition is derived. Numerical results for the input impedance and radiation pattern of the antenna are presented. The antenna factor with the antenna gain is computed to check the possibility of using this antenna as the broadband antenna for the special case in such as electromagnetic compatibility testing. The comparisons of the computed results with measured data are made. These results will allow this antenna to be used with confidence in various applications.

The Performance of a PEMFC stack is strongly dependent on the uniform reactants distribution on MEA. The uniform distribution can be achieved by flow-field pattern and manifold design optimized to satisfy operating conditions. This paper investigates uniform reactants distribution in channels by changing manifold shape and inlet mass flow rate. Typical U and Z shape and modified U and Z shape manifolds with buffer zone were designed. To check the uniform reactants distribution, standard deviation of mass flow rate was compared. The numerical results show that the inlet mass flow rate, inlet shape, and manifolds shape are critical factor for uniform distribution.

Taking a bledes axle of rotary tiller as a example, this paper discusses influences of four loading essential factors, which are strengthened amplitude, cycle times, loading sequence and loading frequency. in fatigue life. Determination principles of above four factors and monitoring methods of fatigue damage by local strain are dealt with. The actual field testing check of farm machinery is rapidly simulated by laboratory program fatigue test can shorten the period of development and improvement of a product. In the time of in-door simulation test, damage monitoring and four loading essential factors, which are strengthened amplitude , cycle times, loading sequence and loading frequency, have to be dealt with . If these problems are solved successfully, it is possible to accelerated test speed, reduce costs and manhours, and raise accuracy of test result. However strengthening method, loading pattern and influence of loading frequency on test result have not so far been discu sed systematically, damage monitoring is even more a difficult problem. Authors have studied above problems with the object of blades axle of rotary tiller.

본 논문에서는 물리적으로 짧은 길이를 갖지만 발룬의 접지면에 원형 slot을 추가하여 최저동작주파수를 확장하고 유전체 적층구조 이용하여 평형급전특성을 개선한 소형 광대역 발룬을 설계하였다. 설계한 발룬은 반사손실 -10 dB 기준으로 1~7 GHz에서 동작하며 1 GHz 기준으로 전기적 길이는 $0.05{\lambda}$ 이다. 그리고 평형급전특성이 개선된 효과를 검증하기 위하여 제안한 발룬과 간단한 다이폴을 결합하여 방사패턴을 측정하여 패턴의 왜곡정도로 발룬의 성능을 검증하였다.

NMOS IC layout에서 직사각형 도형의 갯수에 비례하는 검사시간을 소모하는 설제규칙 검사의 알고리즘의 제안되고 그것에 의한 program이 개발 되었다. 일반적인 설계규칙 검사 algorithm의 시간소모는 0(nlogn) 혹은 0(n**1 . 2)에 비례하는데 반하여 (n은 직사각형 도형의 갯수) 이 논문에서는 pattern의 DF(direct format) data와 bit-map plane을 연관 지음으로써 0(n)에 비례하는 시간소모를 달성 할 수 있었다.

An analysis method for the electromagnetic scattering of a gaussian beam wave by finite periodic conducting strip grating on a groudned dielectric slab is considered. The intergral equation for the unknown current induced on the conducting strip surface is derived and solbed numerically by use of the method of moment. From knowledge of the strip current, the quantities of interest such as radiation pattern, the space wave power radiated into the free space, and the coupled surface wave power propagating along the dielectric slab are computed for the appropriately chosen parametes Some similarity between scattering behaviours of the present geometry and the infinite geometry is examined by observing the Off-bragg as well as bragg blaxing penomena in both geometries.The validity of the numerical results are assured by a check of the power conservation relations.

In this paper, there is intended to introduce the new tunnel face shape, that is concave shaped face, and discusses its effects on the tunnel stabilization. Therefore, a comparative analysis in which the stability of a concave face was compared to that of a conventional plane face on the basis of displacement patterns in the tunnel face was conducted using a model test. In order to check and confirm displacement patterns on the concave face according to the radius of curvature as well as those around the face according to lateral pressure coefficient(k), two experimental concave models, produced at a scale of 1:2 and 1:5(tunnel radius), of the forefront of the curved area extended from plane face was built and tested.
