This paper presents a software design simulation method for controlling multiple mechanism carrier system (MMCS), which is mainly used in a wrapping machine or a case packing machine. This method uses a mechanical tool-work interactive model proposed in this paper, in order to represent the interactive behaviors between some tools and a work driven by their tools, in which low effect states of a work are defined. Based on this method, a 3-D simulation system has been built. It consists of shape modeling of each device, behavior definitions of tools, and control logic using if-then expression. By applying it to a ase packing machine having about 30 mechanical devices and 100 inputs/outputs for control, the effectiveness of this method has been shown in general verification of control logic specification in an early software design phase and the possibility of smooth communication tool between mechanical and software designers.

The blanking interface between an ES system and a radar system on the same platform cause the unwanted radar signal separation in the process of the signal measurement of the ES system. In this paper, we propose the novel radar signal blanking method for ES. The proposed method extracts a standard of judgement which we can decide whether a radar signal is separated by the blanking interface and presents how to merge the separated signals. Test result is presented to show the performance of the proposed method.

The purpose of this study is to assess and develop effective MIS planning method by applying the CSF method. With the comparative analysis of the Rockart's basic concept of CSF and the examples of the corporations which employed CSF methodology, a new CSF method more suitable to Korean business environment is proposed and applied to another company for evaluation. The new CSF methodology consists of three steps. The first step is to preexamine the business conditions. The second step contains an Introductory Workshop, interview with the managers, survey questionnaire, Focusing Workshop, and decision of the priorities for system development. The third step is a real development of an information system out of the first and second steps. As a result of this study, it is found that revised CSF method can induce top management to participate more in the activities of information system development and that it can make top management to focus on the critical area. The fulfillment of the information requirement out of the enhanced MIS planning will lead to more successful management activities.

In this paper, we focus on the process of using open source software (OSS) and factors that should be considered when using project-based OSS. We also elaborate on how to avoid using OSS licenses in an OSS-based technology development process, why dual OSS licenses and security threats should be avoided, and the method of notification after use. In addition, the OSS license verification method and environment are described in the course of project development. In the verification method, the OSS license used for technology development in the course of project execution is validated in advance by the person who decides whether or not to use the OSS, and then additional verification using the tool after technology development. It is expected that this paper will be helpful for establishing the OSS usage consideration and the license verification procedure, and environment in the future.

Requirements traceability link information is the basis for determining whether requirement change requested throughout the software development life cycle should be reflected in the system. Setting up complete requirements traceability links requires considerable effort. However, the commensurate benefits can be obtained in later development or further maintenance phases. For this reason, setting up and managing requirements traceability links in the software development phase are tasks that cause considerable resistance to developers. This study proposes a method for generating requirement traceability links in business applications. The key feature of the proposed method is that the traceability link from the requirements element, which is the basis of the corresponding element to the analysis element, is automatically established at the same time the elements of the analysis model are identified. This can be a way to reduce developer effort while increasing the efficiency of the traceability model. A case study on a Course Registration System demonstrates the feasibility of applying the proposed requirements traceability management method to actual software development.

The defense system development process is a process of developing various systems that perform functions in various functional areas such as battlefield awareness, command control, force application, and logistical support. In other words, the defense system development process is a process of developing many systems simultaneously in various functional areas. Various systems developed through this process should be interoperable so that they can be integrated and operated in a joint warfighting environment. To successfully implement this, the US Department of Defense uses the Joint Capability Integrated Development System(JCIDS) for the defense system development, and within this JCIDS processes the Capability Based Assessment(CBA) methodology as its core technology. This CBA methodology transforms the mission activity requirements to functional capability requirements logically and transforms the functional capability requirements to system requirements logically also. Smart City is a city that improves the convenience and quality of life of the citizen by integrates various systems that perform various functions of the city and smarties various functional systems with smart services by using IT technology. In other words, defense system development and smart city development have a common feature of the process of developing many systems simultaneously in various functional areas. In order to address the problem of having to develop many systems simultaneously in each functional area, it is important to logically transform the various mission scenarios into functions and logically transform the functions into systems. Therefore, a joint capability integrated development system and its core methodology, Capability Based Assessment(CBA), can be applied to smart city development. This paper proposes a method for performing a smart city concept design method using the capability based evaluation (CBA) method.

Overweight and obesity induce serious health problems that exert negative effects on dog's welfare. Body condition score (BCS) is a common method to evaluate the body fat mass in animals. By palpating and observing fats under the skin it is possible to predict animal's body fat accumulation condition. BCS is also a useful tool to estimate body fat composition in dogs. However, BCS can be subjective when it was performed by non-professionals like pet's owners. To develop a method to avoid the misevaluation of BCS twenty-four Beagles were enrolled and performed BCS evaluation. In addition, the length of chest and abdominal girths were measured. In correlation analysis, the sizes of chest and abdominal girth were significantly correlated with BCS. Especially, the difference and ratio of the chest and abdominal length were highly correlated with the BCS. With that, we suggested that this simple measurement of chest and abdominal girths by a measuring tape would be an effective method to estimate BCS scores in dogs that helps non-professionals to manage their own dog's nutritional condition by monitoring body fat accumulation condition.

The suitability of the pattern manufactured with the development figure was considered by reviewing the development conditions that can be directly connected to the basic pattern in the human body surface development figure with the cast bandage method. The method to prepare the sleeve basic pattern was based on the cylindrical surface development method, and the sleeve basic pattern covering the 45 and 90 degrees momentum of the arm-movement was made by using the cast-type body surface development figure prepared with the horizontal line of the sleeve hem placed horizontally in the plan and by combining the cast-type body surface development figure in the standing position with the figure in the moving position. The test clothing was prepared with the sleeve pattern adding the bodice pattern in the standing position and the momentum and was worn on the FRP replica. The relationship theory of the body surface development figure with the pattern was derived by reviewing the suitability from the wearing state. The sleeve-cap height of the sleeve basic pattern resulted in about 80% in the standing position when the needs for a physical activity are 45 degrees and the about 50% when the needs for a physical activity are 90 degrees. The additional size of the diagonal length of the sleeve-cap could be set as "0" if the sleeve-cap height is low by 50% and as 50% of the additional size in the standing position if the sleeve-cap height is 80%.
