  • This is a dimensionless analysis of interior ballistics for the design of gun tube. One of the characteristics of this analysis is to ues the .ETA.$_{j}$ number which means a relative quantity of virtual work to the kimetic energy of projectile at the muzzle. In order to apply the concept of virtual work, it is assumed that the projectile is moved from the beginning to the end of bore under constant pressure of the certain travel distance of projectile. The principle of the analysis is induced from the Le Duc equation, which expresses velocity as a function of projectile travel and is based on the translation of a hyperbolic curve. From this non-dimensional analysis, the optimum design parameters of pressure in the bore, velocity and acceleration of projectile can be obtained from the table of figure without computation. This method was verified by the experimental work.k.

  • This study is a background for developed woodworking educational program. To achieve the propose of this research, related to handwork to figure out the concept, changes and characteristics of handwork and the products of handwork. The areas of woodworking needs basic hand function of gripping and hooking, strong hands and stability of hand operation. Activities of this area can enhance the ability of controlling the strength of hand and the stability of hand operation. The use of both hands in woodworking promotes the coordination of both hands and handling ability. In the woodworking, diverse functions of hands are used with various tools. Each hand may be move differently, and the hand operation is elaborated. These features of woodworking help growing coordinations and hand function, and developing brain and creativeness.

  • Beauty of balance, can be found in antique furniture of the Joseon Dynasty. Balance, give comfort and peace of mind to people. Even today, the balance in various fields, it is easily viewed, and an important one element indispensable in the design. Various lighting is an essential element of the interior to create an atmosphere of space. It is also useful in a variety of ways for beauty, emotional effect, such as the switching of visual atmosphere. This design was designed with the concept of balanced. In addition, I have applied a simple graphic appearance. To give the fun and tension while giving it a well-balanced when you meet the figure. The design of this study is nothing more than a single direction. It will be in the traveling direction of the future as a designer by using a simple structure and phenomena that appear in life, is given to the design without the feeling of rejection to the user.

  • The purpose of this study is to suggest the design guidance of education facilities by analysing Alvaro Siza's education facilities of which considered having idiosyncratic spatial characteristics. Focusing on the his planning of learning and transitional space of education facilities, this study aims at eliciting the spatial characteristics of his architecture. In doing so, this study tries to figure out his basic method of reification of his basic architectural concept which is articulated in learning space and transitional space of education facilities by introducing the boundary element and penetration of light in order to support student's learning activity and foster abundant cognitive experiences. Therefore, this study presents the feasible supplementary design method for future education facilities to be appropriate not just for quantitative factors, but for qualititative aspects such as user's psychological fulfillment, and emotional satisfaction.

  • The purpose of this study is to develop a guideline of process capability evaluation and to apply this guideline improving the quality of products, especially in the small and medium enterprises. In this study we deal in the concept of process capability evaluation, the calculation of process capability index, and the application of a case study. Man must compare the state of process with the standards in evaluating of the process capability. Control chart can be used as a yardstick for judgement for the long term period and the distribution shape of histogram for the short term period. Man should regard to the significant figure by the calculation of process capability index.

  • The HwaSungSungYouk is one of the construction project in viewpoint of today's construction management and various information how to build the HwaSung at the last of the eighteen century had been recorded in HwaSungSungYoukEuGye. The purpose of this study is to analyse the data in HwaSungSungYoukEuGye in viewpoint of today's construction management for estimating the resources of PalDal-mun construction. In the record, there are a 10t of information relate to time management, cost management and human resource management, and the concept of modern construction management will be also use to figure out the construction data of the HwaSungSungYoukEuGye.

  • The Improved Deterministic Truncation of Monte Carlo (iDTMC) is a powerful acceleration and variance reduction scheme in the Monte Carlo analysis. The concept of the iDTMC method and correlated sampling-based real variance estimation are briefly introduced. Moreover, the application of the iterative scheme to the correlated sampling is discussed. The iDTMC method is utilized in a 3-dimensional small modular reactor (SMR) model problem. The real variances of burnup-dependent criticality and power distribution are evaluated and compared with the ones obtained from 30 independent iDTMC calculations. The impact of the inactive cycles on the correlated sampling is also evaluated to investigate the consistency of the correlated sample scheme. In addition, numerical performances and sensitivity analysis on the real variance estimation are performed in view of the figure of merit of the iDTMC method. The numerical results show that the correlated sampling accurately estimates the real variances with high computational efficiencies.

  • Current city that we live in exist many modern architecture have historical meaning and high value. This modern architecture is disappearing because study - definite thesis of concept, division of the time - of preservation wasn't advanced fully and we have the feeling of being victimzed for Japanese imperialism, in addition to lack of recognition for cultural treasure value. These days, a growing number of people tend to focus on preservation and uses of cultural properties including mordern architectures. Therefore, this study aims to figure out constructive uses of mordern architectures by purposing analysis and preservation methods with a selected architectures which deserve to be conserved.

  • Since the concept was first introduced in the 1970s, transit-oriented-development (TOD) has greatly expanded in East Asian cities such as Hong Kong. Rail stations are built together with clusters of residential-commercial towers and government services to form a new style of living - a "rail village." This paper examines the composition, scale, spatial form, organization and operation of several typical rail villages in Hong Kong. The cases range across those planned from the mid-1990s to 2015. Based on the analysis of the rail village composition, the paper derives a development ratio to indicate the density, effectiveness and efficiency of a rail village catchment area. The ratio provides a useful and direct figure for the comparison of different stations, cities and development modes.
