  • Recently, component-based software development is getting accepted in industry as a new effective software development paradigm. Since the introduction of component-based software engineering (CBSE) in later 90's, the CBSD research has focused largely on component modeling, methodology, architecture and component platform. However, as the number of components available on the market increases, it becomes more important to devise metrics to quantify the various characteristics of components. In this Paper, we propose metrics for measuring the complexity, customizability, and reusability of software components. Complexity metric can be used to evaluate the complexity of components. Customizability is used to measure how efficiently and widely the components can be customized for organization specific requirement. Reusability can be used to measure the degree of features that are reused in building applications. We expect that these metrics can be effectively used to quantify the characteristics of components.

  • In so many real estate development projects, there were strong needs to have a powerful tool to check feasibility of those projects. But there were not enough tool and measure to cover risk of real estate development and construction. Therefore I tried to find a real tool to measure investment value of development properly and efficiently, by means of case studies of many real estate development projects. Finally I found a fact that no tools of investment value analysis are perfect and efficient to hedge all kinds of risks in projects. Especially NPV(Net Present Value) and IRR(Internal Rate of Return) were not sufficient by themselves to measure investment value. So I found out that MIRR(Modified IRR), XIRR(X-IRR), ARR(Average Rate of Return), PP(Payback Period) and so on, would be supplementaries of proper and efficient investment value analysis.

  • In this paper, we present a novel pulse train identification method for two step stagger pulse train. Generally radar uses a fixed pulse train, and it is easy for electronic warfare system to measure the pulse repeat interval(PRI) and identify the radar. But it is very difficult to measure the PRI of stagger pulse radar because the pulse interval is periodically changed. We suggest a novel method to measure the PRI and identify the radars using the second deviation of pulse train. This method is faster comparing with Histogram method. We have a good PRI measurement results for 2 step stagger signals.

  • In order to increase the accuracy and efficiency in measuring obesity conducted outside the hospitals, we examined not only the Body Mass Index and cutoff values of waist circumference of 3,281 adults but also considered their gender, age and various body characteristics. This study included 1,505 males (45.9%) and 1,776 females (54.1%) who visited the comprehensive health checkup center. The average body fat content of male participants was 22.2%, and their Body Mass Index was 24.4kg/$m^2$. The average Body Mass Index of female participants was 22.9kg/$m^2$. The average of waist circumference of male subjects was 86.2cm while that of female subjects was 76.9cm. The conventional method to measure obesity using BMI and WC only does not reflect the actual body fat which may change according to one's gender and age. Therefore, for those who visit individual's place to measure obesity outside the hospitals only based on BMI and WC, we need a new standard to measure obesity more accurately.

  • Cooling towers have been installed on rooftops or outside of buildings and widely applied to control the indoor temperature in residential areas and buildings. However, the noise and vibration resulting from their operation may cause problems in adjacent buildings. The purpose of this study is to measure the noise and vibration of an industrial cooling tower located adjacent to industrial plants and to investigate its influence on the surroundings according to an authorized evaluation standard. Further, in order to measure the effect of the vibration of the tower on the precision equipment inside the plant, an experiment is conducted to measure the vibration of the ground in the plant and the targeted precision equipment. The measurement results indicate that the noise in the cooling tower is 4 to 9 dB(A) higher than the maximum level defined in the standard of 68dB(A). The effect of the vibration of the tower on the precision equipment is comparatively minimal, because that in the supporting frame of the building is weaker than that on the floor where the precision equipment is located. The vibration of the floor on.

  • SCM system is required inter-industrial cooperation as well as inter-organizational cooperation. It means not only standardization of inter-organization but also standardization of inter-industry. SCM makes possible one circulation from fiber to retail industry in the respects of information and product flows. QR is the SCM of textile apparel industry, which satisfy customer need with least cost and maximum profit. Customer-oriented supply chain system focused on information sharing, cost reduction, inventory control, lead time reduction, quick response on customer demand. How we can measure the performance of successful SCM is issued on the approach of Balanced Scorecard which evaluates 4 perspectives such as customer perspective, internal business perspective, financial perspective, and innovation and learning perspective. This can project the blueprint of textile fashion business to right direction with vision.

  • This paper deals with method to measure the user's driving-will force and to control the power-assisted wheelchair. To solve this problem, we extract the user's driving-will by using the mathematical motor model. And then, we get the linear and angular velocity at the center of the vehicle. Wheel velocities are also measured from center velocity. Finally, power-assisted electric wheelchairs are controlled by these data. Here all processes are verified by simulation.

  • Successful Six Sigma methodology involves continual success of projects, each incrementally moving the organization closer to its strategic goals of shareholder return and customer satisfaction. However, Six Sigma methodology has some disadvantages in long-term technical strategy parts, systematic technology management techniques and concrete idea creativity methodology. To complement these Six Sigma problems, Triz technique is considered. Triz focuses on solving such problems efficiently, effectively, and creatively. The purpose of this paper is to improve the temperature inspection method of a refrigerator through the DAGEV(Define-Analyze- Generate-Evaluate-Verify) cycle of Triz.
