3D SCAN enables easy human body measurement via a digital method in the process of film costume production which used to be done manually. Software-oriented computer graphic, which integrates 3D SCAN data in the process of manual film costume production, can induce quick and diverse design outcomes. While, 3D PRINT, which integrates computer graphic data in the process of manual film costume production, can automate the process of special costume production using a digital method. Integration of 3D Scan + Computer Graphic + 3D Print using integrated platforms for tailored costume production as developed in this study allows significant reduction of costume production period and costs. It also allows efficient integration of costume production outcomes in various industries related with OSMU contents in particular. In other words, using it, we can create a new business market that integrates multiple areas of film content, drama content and game content.

Ferroelectric thin films have attracted much attention for applications in nonvolatile ferroelectric random access memories(NVFeRAM) from the view points of high speed operation, low power consumption, and large scale Integration[1,2]. Among the FRAM, BLT is of particular interest. as it is not only crystallized at relatively low processing temperature, but also shows highly fatigue resistance and large remanent polarization Meanwhile, these submicron ferroelectric capacitors were fabricated by a damascene process using Chemical mechanical polishing (CMP). BLT capacitors were practicable by a damascene process using CMP. The P-E hysteresis were measured under an applied bias of ${\pm}5V$ by using an RT66A measurement system. The electric properties such as I-V were determined by using HP4155A analysers.

Electron beam lithography is one of the importnat technologies which can delineate deep submicron patterns. REcently, electron beam lithography is being applied in delineating the critical layers of semiconductor device fabrication. In this paper, we present a development simulation program for electron beam lithography and study the development profiles of resist when resist is exposed by the electron beam. Experimentally, the development parameter of positive and negative resists are measured and the data is applied to input parameter of the simulation program. Also simulation results are compared of the process results in the view of resist profiles. As a result, for PMMA and SAL 601 resist, the trend of simulation to the values of process parameters agree with real process results very well, so that the process results can be predicted by the simulation.

Recently, Korean software industry has enjoyed fast growth, thus phenomenon drew attention to the need for more precise and standardized cost estimation system for software development. However, many obstacles exist in achieving a more precise and universally applicable cost measurement. These obstacles include : (1) the intangible nature of intellectual efforts, (2) lack of cost standards, (3) lack of quantitative yardstick to determine the potential complication, (4) lack of both cost monitoring during development and coordinating between acquisition process and cost estimation. The purpose of this study is to facilitate software development cost estimation considering acquisition process that will meet korean user's needs, and to create better models that will be cost for software development particularly for Korean environment.

This study is a measurement of effectiveness to a job process for the hospital information system (HIS) used in the hospital industry. Using the effectiveness scale that I developed in the questionnaire of the ISO9241-11 quality model, I measured the importance level of HIS and its significance on a job practices in the large general hospitals within the country. The questionnaire showed that the importance level of domestic HISs was highest in the system used by staffs(mean=3) and to reduce a job process and increase the efficiency of work.

Physical therapists use assumptions about motor control in every aspect of their work in treating stroke patients. An understanding of the recovery process after stroke, some neural mechanism of recovery and therapeutic model is critical factor for physical therapist to evaluate and obtain a higher final stage of recovery. The purpose of this article was to review the recovery process after stroke, some neural mechanism of recovery, the role of rehabilitation in the process of recovery, therapeutic model and its limitation. This article will help understanding of recovery process. evaluation, and treatment of the stroke patients. Each therapeutic method consists of a different set of assumptions and they are not completely independent of one another. Therefore specializing in any techniques of physical therapy will not be enough to treat stroke, so we are in need of integrated approach and objective measurement instrument to adequately evaluate and treat stroke patients.

Carbon nannofiber reinforced Cu matrix composite has potential applications for electrically conducting materials having high strength and electrical conductivity. In this study, we have developed fabrication technology of the nanocomposites using a liquid pressing process. The process is to use the low pressure for infiltration of Cu melt into carbon nanofiber mat as the Cu melt is pressurized directly. The minimum pressure required for infiltration was calculated from force balance equation, permeability measurement and compaction behavior of carbon nanofiber. Also, the melting temperature and the holding time have been optimized.

An on-line measurement of the workpiece hardened depth in laser surface hardening processes is very much difficult to achieve, since the hardening process occurs in depth wise direction. In this paper, the hardened depth is estimated using a multilayered neural network. Input data of the neural network are the surface temperatures at arbitrary chosen five surface points, laser power and traveling speed of laser beam torch. To simulate the actual hardening process, a finite difference method(FDM) is used to model the process. Since this model yields the calculation results of the temperature distribution around the workpiece volume in the vicinity of the laser torch, this model is used to obtain the network's training data and laser to evaluate the performance of the neural network estimator. The simulation results show that the proposed scheme can be used to estimate the hardened depth with reasonable accuracy.

Recently groupware has been popularly adopted by corperations to gain competitive position. In Korea, one of major function of those systems is the Electronic Authorizing System because korean firms have authorizing system but western firms do not. Thus researches on EAS has never been produced before. The purpose of this research is to build the research framework for productivity measurement of EAS. The research model of EAS has investigated three dimensions including Business process, ease of system use and media richness to meet this end. Based on this model, author conducted case study with mailing questionaires. The result of research shows that the factors of the business process and ease of system use raise the productivity but the factor of electronic media a little decreases it. Also author finds business process affects the productivity in three ways such as changing layout of papers for authorizing, changing business process and removing waiting time for authorization. Finally, based on the result of research, this paper adds some recommendations for EAS builder.

Data mining technique is the exploration and analysis, by automatic or semiautomatic means, of large quantities of data in order to discover meaningful patterns and rules. This paper uses a data mining technique for the prediction of defect types in manufacturing Process. The Purpose of this Paper is to model the recognition of defect type Patterns and Prediction of each defect type before it occurs in manufacturing process. The proposed model consists of data handling, defect type analysis, and defect type prediction stages. The performance measurement shows that it is higher in prediction accuracy than logistic regression model.
