This paper presents a new approximation for the crystalline lens of the human eye with refracting surfaces based on schematic eye during accommodation. A new model eye describes the iso- indical profiles in the form of symmetric spherical surfaces. A vary important condition which was imposed upon the parameters (thickness, radius) was the lens volume conservation during accommodation.

갱폼이라 함은 주로 고층 아파트에서와 같이 평면상 상ㆍ하부 동일 단면 구조물에서 외부벽체 거푸집과 거푸집 설치ㆍ해체작업 및 미장ㆍ치장(견출) 작업발판용 케이지(cage)를 일체로 제작하여 사용하는 대형 거푸집을 말한다. 여기서 케이지는 갱폼에서 외부벽체 거푸집 부분을 제외한 부분으로 거푸집 설치ㆍ해체작업, 후속 미장, 치장(견출) 등 작업을 안전하게 수행하는데 필요한 작업발판, 안전난간 등으로 구성되어 갱폼 거푸집에 결합된 부분이며, 상부 케이지는 갱품 케이지의 4단 작업발판 중 거푸집 설치ㆍ해체작업용으로 사용되는 상부 2단 작업발판 구성 부분이고, 하부 케이지는 미장ㆍ치장(견출) 작업용으로 사용되는 하부 2단 작업발판 구성 부분을 말한다.(중략)

Organic mercurial fungicides, for seed treatments and dust formulations, has been increasingly used by farmers. Evaluation of the purity of organic mercurial fungicides has been performed by precipitation method at this laboratory. There are several methods for the an alyses of organic mercuric formulation, among which are (1) Precipitation met hod, (2) Volatilization method, (3) Volumetric method, and (4) Dithizon method. These methods, however, show some deffects in specificity (differentiation of organic form) and quantitativity. Polarography applied for the estimation of phenyl mercuric acetate was found to be simple, rapid and accurate. Tile fundamental method of polarography arid accuracy of analysis are discussed statistically and a satisfactory results was obtained.

In this paper, we present an online scheme for parameter estimation of solar cell, based on the model adjustment technique and a genetic algorithm. The ideal diode model and the diode model with series and shunt resistor are used to estimate their parameters. Simulation works using field data in the form of a VI characteristic curve are carried out to demonstrate the effectiveness of the proposed method.

This study investigates the temperature rise of reinforcement bars located in the middle of the form (for reinforcement concrete) during hot weather condition. The temperature was measured for three consecutive days before placing concrete. Test results showed that the temperature started to increase at 7:00 AM before sun rised, and peaked at around 2:00 PM. It was found that the thinner the diameter of a reinforcement bar, the higher is the speed of temperature rise and drop of the bar. The peak level of temperature for D13, D19, D25 and D32 was 54.4℃, 55.2℃, 56.4℃ and 60.2℃, respectively.

In this paper, for n = 2m and odd prime p, new generalized bent functions from the finite field F$\_$p$^n$/ to the prime field F$\_$p/ are constructed from the partial spreads for F$\_$p$^n$/. Closed form expressions for the proposed generalized bent functions and their trace transform are derived in the form of the trace functions. The trace expressions for the bent functions and their trace transforms defined on F(equation omitted) constructed by using PS- are also derived.

This study addresses a microfluidic method to uniformly form diacetylene (DA) liposomes and control their size. DA liposomes are biochemical sensor materials with a unique property such that when they are polymerized to polydiacetylene (PDA) they exhibit non-fluorescent blue to fluorescent red phase transition upon chemical or thermal stress. The liposome size and distribution are important because they significantly affect the phase transition. So far, DA Liposomes, have been prepared by mixing of bulk phases leading to heterogeneous, polydisperse distribution in size. Therefore, additional post-processes are required such as sonication or membrane extrusion to obtain an appropriate size of liposomes. Here, we report a novel strategy using a microfluidic chip and hydrodynamic focusing to form DA liposomes and control their size. Preliminary results obtained by scanning electron microscope (SEM) and dynamic light scattering (DLS) show that the microfluidic strategy generates more monodispersed liposomes than a bulk method.

최근 국내 아파트의 외벽 거푸집공사의 경우 대부분 갱폼 시스템을 통해 철근콘크리트 구조체를 시공하고 있다. 이러한 갱폼 거푸집을 사용한 콘크리트의 경우는 거푸집 탈형 후 외부환경에 노출되고 특히, 건조한 봄, 가을과 일사량이 높은 서중시기의 벽량이 많은 아파트 측벽에 다량의 균열이 발생되어지고 있다. 이에, 본 연구에서는 신축 아파트 건설현장 중심으로 균열량이 많은 아파트 측벽부분의 갱폼시스템에 습윤양생 자동설비장치를 적용하여 초기 콘크리트 양생에 필요한 수분을 공급함으로써 콘크리트의 품질확보와 다량의 측벽균열 저감을 통한 습윤양생 자동장치의 효율성 및 활용성을 검토하고자 하였는데, 그 결과, 양생 효과 및 낙수량 고려 시 습윤양생 자동장치에 0.3mm 사이즈의 노즐을 사용하여 살수양생을 실시할 경우, 자원낭비 없이 콘크리트의 품질향상 및 균열저감에 효과적인 것으로 판단되었다.
