The property of concrete at different places in mass concrete is affected by the age under the same curing temperature. For more accurate analysis of thermal stress in mass cocnrete, it is necessary to obtain the property of concrete with age and curing temperature. In this study, the effects of curing temperature and age (Maturity) on the development of the property of concrete were investigated by using concrete specimens made with type I cement. The curing temperatures are 23$^{\circ}C$, 5$0^{\circ}C$, and 8$0^{\circ}C$, respectively. As the maturity increases, the strength of concrete was increased. The results obtained experimentlly was compapred with the previous models, and good agreements was obtained.

In this paper, viologen derivative is used as charge transfer material to develop sensors for detecting the organic pollutants which are the main reason of harbor pollution. We fabricated self-assembled monolayers of viologen derivative on gold electrode of QCM and investigated an electrochemical behavior property. We also determined electrochemical sensing property about environmental pollution materials such as bezene, phosphate and surfactant through quantitative and qualitative analysis of charge transfer using intrinsic property of viologen derivative by temperature and concentration change. From the achieved results, we can apply and develope the detecting sensors for harbor pollutants.

The purpose of this study is suggesting a basic data for which scientific preservation and rehabilitation of future modern architecture through the analyzing property of clay brick used in modern architecture in a scientific way.The clay brick which is used in the early 1900s has even lower property than present clay brick because of poor plasticity technique at that time. It could be possible to property and effective stability examination of modern architecture from nondestructive testing is significantly associated with property.

블럭계획에서 조화행렬(concordance matrix)이 퍼뮤테이션 행렬(permutation matrix)들의 크로네커 곱(Kronecker product)의 선형결합으로 표시되면, 그러한 블럭 계획들은 특성치 C (Property C)를 갖고 특성치 C를 갖는 블럭계획들은 역행렬의 계산없이 블럭내 분석이 가능하다(Paik, 1985). $L_i$ 계획($L_i$ PBIB design)이 특성치 C에 속하는 것을 보이기 위하여, 조화행렬의 구조가 다중순환형식임을 보였다.

This paper presents a changes of luminescence property for converted white LEDs with the commercially available silicate phosphor. If silicate phosphor's quantity increase step by step. luminescence property will be changing. we analyze luminescence property for these change and carry out the high temperature aging test for 7,000 hours, the high temperature and humidity aging test for 7,000 hours for reliability. LED degradation not only results in reduced light output but also in color changes. so we monitor correlated color temperature (CCT), chromaticity coordinates(x, y) and spectrum intensity. Those results suggest that humidity factor more bad effect in color changes than temperature factor and Lighting quality is related with quantity of phosphor.

The Purpose of this study is to clarify what a difference the individual family value and relationship make on the inheritance consciousness by focussing on right succeed property among the inheritances rights of family. Questionnaire were distributed to about 450 married person with children over 40 year and among them 384 cases are used in final analysis. Inheritance consciousness of the Korea family shows that the property inheritances to greatly different from the inheritance the family head rituals according to consciousness of the individuals. That is to say the succession of the property is decided by inheritances of the individuals where-as these of the family head and rituals are done by the family norm. such results tend to be made due th the fact that Koreans think of a duty to father a son and make him succeed th the heat of the family on the basis of the strong blood tie of the family that Koreans think t important to keep their family fame and to contain the fam ly existence I. e. they respect their patriarchal system.

In this article, we shall prove a common fixed point theorem for two weakly compatible self-maps 𝒫 and 𝔔 on a dislocated metric space (M, d^*) satisfying the following ξ-weakly expansive condition: d^*(𝒫c, 𝒫d) ≥ d^* (𝔔c, 𝔔d) + ξ(∧(𝔔c, 𝔔d)), ∀ c, d ∈ M, where $${\wedge}(Qc,\;Qd)=max\{d^*(Qc,\;Qd),\;d^*(Qc,\;\mathcal{P}c),\;d^*(Qd,\;\mathcal{P}d),\;\frac{d^*(Qc,\;\mathcal{P}c){\cdot}d^*(Qd,\;\mathcal{P}d)}{1+d^*(Qc,\;Qd)},\;\frac{d^*(Qc,\;\mathcal{P}c){\cdot}d^*(Qd,\;\mathcal{P}d)}{1+d^*(\mathcal{P}c,\;\mathcal{P}d)}\}$$. Also, we have proved common fixed point theorems for the above mentioned weakly compatible self-maps along with E.A. property and (CLR) property. An illustrative example is also provided to support our results.

지적재산권보호를 위한 국제협약은 범세계적이거나 지역적차원에서 이미 한 세기 전부터 존재하여 왔다. 우리나라도 국제협약에 적극적으로 가입하고 있다. 이후 국제협약을 어기고 모방사례가 계속 발생시 국가 신인도 문제뿐만 아니라 국제 무역 시장에서 활동하는데 어려움을 겪게 될 상황이 예견된다. 이에 따라 포장디자인의 지적재산권제도의 국내외 현황조사와 모방사례를 분석하고 지적재산권제도의 이해도와 관심도 연구조사를 통하여 포장디자인의 지적재산권 보호제도의 중요성을 인식시키고 WTO체제하에서의 패키지디자인 지적재산권 보호 방안을 연구하는데 본 논문은 주력하고 있다. 본 연구에서는 인트라넷을 이용한 기업의 디자인 정보공유시스템 디자인 구축과정을 롯데백화점 디자인실의 사례를 통해 살펴보았다. 기업의 인트라넷의 온라인시스템을 구축할 때의 요구사항과 필요기능을 제시하였고, 핵심기능에 대한 구현을 제시하였다. 본 연구의 목적은 새로운 개념의 정립이나 기반의 발견에 있는 것이 아니라, 개방성에 의해 사용이 편리한 인터넷 환경을 조직의 기반 디자인 정보공유시스템 구축에 적용하는 인트라넷 개념을 사례를 통하여 구현의 효과와 구축방법을 제안함에 있다. 이를 위해 본 논문에서는 패키지디자인의 지적재산권보호제도의 보호방안을 마련하기 위한 보호제도 현황분석과 분쟁사례연구를 통한 분석과 각종 통계자료 제시, 국내외 패키지디자인의 지적재산권 침해 모방사례 분석 및 소비들과 관련 패키지디자인 업무 종사자들의 실증적 설문조사 분석을 통하여 실질적인 보호 방안을 연구하고 제시하고 있다.

Dynamic characteristics of a wrist power transmission examine closely with mass property, to present a model which is able to induce the vibration is ultimately the purpose. A robot wrist power transmission for analysis model gets the mass property through the approach to be the experimental. A bearing equivalent stiffness which supports the axis and a gear contact equivalent stiffness are determined by the simplicity analysis model compared the result of the experiment. We calculate the vibration tendency of the robot wrist power transmission by an analysis tool which is called the RecurDyn. We compared it with a signal analysis experiment's which a robot operation happens which is based on the ambient noise.
