Cavity in the mold is exposed to high pressure during injection molding operation. Injection molded articles with deep depth are often demanded as design variety increases. Subsequently mold becomes weak and deformation increases as the mold depth increases. Thus the injection molds for deep depth articles should be designed to hold out high pressure or stress concentration and large deformation. Through this study, equation for mold design was examined and suggested novel method to determine equation for mold design with deep depth. Novel equation developed in this study was modified from beam theory considering cantilever and two points bending situation while previous equation was modified from just cantilever bending situation. The validity of novel equation was verified through computer simulations for various mold side and wall thickness.

Themed hotels is a new form of hotel development that is rising at home and abroad. In the hospitality industry has a leading position. And The design of the themed hotel is different from tradition as hotel as it more innovative. People are attracted to themed hotel for its' unique interior design especially the guest room. For the sake of promoting the themed hotel's running better, guest room design characteristics can't be neglected. Therefore, this paper will analyze the characteristics of the guest's room design in the themed hotel. This paper initially narrates the concept, features and current situation, and then makes an analysis about the types of theme hotels in combination with examples. Secondly, through the thesis analysis of prior research, key words, hybridity, interactions, symbolic, diversity and regionalism about features of rooms in theme hotel are given. Finally, examples about theme hotels at home and abroad opened after 2005 are taken as the center, through which features of rooms in each theme hotel are analyzed. By the analysis of conclusion, basic current situation of rooms in theme hotels is given. The findings of this research will provide a reference to design the guest's room of the themed hotel.

피난과 관련된 대부분의 사인시스템은 벽의 상단부에 있다는 점에서 고개를 숙인 채 대피해야 하는 지진 상황에서 유용하지 않다. 본 연구는 지진 대피 상황의 분석과 이해를 바탕으로 신속한 지진 대피를 위한 대책으로서 사인 시스템을 제안하고자 한다. 첫째, 지진 대피 상황의 동영상 분석을 바탕으로 지진 상황을 이해한다. 둘째, 지진 상황에서 안전한 대피를 돕는 사인 시스템이 가져야 할 필요요건을 도출하였다. 셋째, 현장조사를 통해 국내에 설치되어 있는 사인시스템이 지진대피 상황을 위한 피난설비로서 적절한 기능을 갖추었는지 적합성을 고찰하였다. 동영상 분석 및 현장 조사를 바탕으로 피난유도등의 설치만으로는 지진 상황에서 신속한 대피를 유도할 수 없다는 결론을 도출하였다. 본 연구에서는 피난유도등 근처에 사인시스템을 설치하여 문의 사용성을 돕는 사인시스템을 제안한다.

Recently, the service for nursing home has been transforming in an overall way, and along with that, the supply of the recuperation facilities for the elderly has been expanding. However, the quantitative expansion of those facilities has not been accompanied by the qualitative supply. In consideration of those shortcomings of the existing facilities, it may be necessary to ensure an improvement in qualitative terms. This study investigated and analyzed the Nursing home, examined the current situation, reconsidered the state of recuperation facilities for the elderly as part of effort to prepare for the silver society, and present measures for improvement in an attempt not to repeat mistakes that have been observed in the existing facilities in planning Nursing home that will be open and built in the upcoming days, which aimed to provide basic data that can be used in the future and explore the direction of relevant design.

Existing non-manifold data structures which use the ordered topological representation method, are designed based on a "Model" which is the highest topological entity. Their non-manifold information is always included in edges and vertices even if they are in the manifold situation. Thus they require large storage spaces than manifold data structures. The proposed data structure reduces its storage space by removing unnecessary information stored in edges and vertices. Topological information is classified into manifold and non-manifold information. The main non-manifold information is radial cycles and disk cycles. The proposed data structure always stores manifold information. For the non-manifold situation, the edge stores radial cycles, and the vertex stores disk cycles. The storage space can be reduced in the later stage of CAD design when the ratio of non-manifold to manifold entities is small.

We examine spectrum sensing in a situation of uncertain channel model. In particular, we assume that, besides additive noise, the observed signal contains an interference term whose probability distribution is unknown, and only its range and maximum power are known. We discuss the evaluation of the detector performance and its design in this situation. Although this paper specifically deals with the design of spectrum sensors, its scope is wider, as the applicability of its results extends to a general class of problems that may arise in the design of receivers whenever there is uncertainty about how to model the environment in which one is expected to operate. The theory expounded here allows one to determine the performance of a receiver, by combining the available (objective) probabilistic information with (subjective) information describing the designer's attitude.

This paper discusses the use of projections for the sums of squares in the analyses of variance for two-way nested design data. The model for this data is assumed to only have random effects. Two different sizes of experimental units are required for a given experimental situation, since nesting is assumed to occur both in the treatment structure and in the design structure. So, variance components are coming from the sources of random effects of treatment factors and error terms in different sizes of experimental units. The model for this type of experimental situation is a random effects model with more than one error terms and therefore estimation of variance components are concerned. A projection method is used for the calculation of sums of squares due to random components. Squared distances of projections instead of using the usual reductions in sums of squares that show how to use projections to estimate the variance components associated with the random components in the assumed model. Expectations of quadratic forms are obtained by the Hartley's synthesis as a means of calculation.

The purpose of this study is to construct the database and to analyze the space and to suggest the possibility of application for architectural planning and design through the approach analysis for educational facilities with the use of the GIS. The properties of the space is to be expressed by optimized path from the analysis of the user and the traffic situation. Analyzed with other site analysis factors(situation, view, noise, configuration of the earth, etc.), the total site analysis is to be made and it is also to be a decision making support system.
