  • The vacuum-cleaner had made the burden of house chore lighten but the operation labour of a vacuum-cleaner had been so severe. Recently, the cleaning robot was producted to perfectly solve the cleaning labour of a house but it also was not successful because it still had a problem of mess-cleaning, which is the clean-up of big trash and the arrangement of newspapers, clothes, etc. The cleaning robot is to just vacuum dust and small trash and has no function to arrange and take away before the automatic vacuum-cleaning. For this reason, the market for the cleaning robot is not yet built up. So, we need a design method and technological algorithm of new automatic machine to solve the problem of mess-cleanup in house. In this paper, a Home Mess-Cleanup Robot(HMR), which has a practical function of the automatic mess-cleanup, is developed. It need functions of agile automatic navigation, novel manipulation system for mess-cleanup. The automatic navigation system has to be controlled for the full scanning of living room, to recognize the absolute position and orientation of the self, the precise tracking of the desired path, and to distinguish the mess object to clean-up from obstacle object to just avoid. The manipulation system, which is not needed in the vacuum-cleaning robot, must have the functions, how to distinguish big trash to clean from mess objects to arrange, how to grasp in according to the form of mess objects, how to move to the destination in according to mess objects and arrange them. Then, it should be an intelligent system so that the mess cleaning task can be autonomously performed in a wide variety of situations and environments. It need to also has the entertainment functions for the good communication between the human and HMR. Therefore, the Home Mess-cleanup Robot with Entertainmental Human Interface is developed in this paper. Finally, the good performance of the designed machine, HMR'4, is confirmed through the results of the mess clean-up and arrangement.

  • So far, many simulation researches associated with naval ships have been concentrated on the tactical systems and naval ship development. However, studies on the improvement of living conditions for naval ship crews were limited. This study targets a crew mess room which is a typical welfare facility in naval ships and existing modeling and simulation methodologies for naval tactical and strategic systems cannot be applied to the crew room simulations. This paper suggests a simulation modeling framework based on 3-dimensional discrete event simulation methodology for crew mess room congestion assessment and operation scenarios. The simulation modeling framework is verified through practical case simulations. The purpose of simulation modeling framework consists of process and system architecture for operation feasibility tests of welfare facilities in naval ships and is to guide an assessment of the operability performance of a crew mess room.

  • The purpose of this study was to understand purchasing behavior on sauce products and the credibility of advertisement in Busan. For the study, 240 of samples taking cooking courses at welfare centers and private institutes were selected. The questionnaire consisted of demographic characteristics, the practical situation of purchasing sauce products, and the credibility of mess media advertisements. 260 questionnaires were distributed, among which 240 were returned and 233 were used for statistical analysis. The result of the study was as followed. Considering the practical situation of purchasing, the samples took information about sauce products from discount markets, and TV advertisements. Purchasing sauce products was done by themselves, and the main reason that they didn't purchase was health. Seeing the credibility of mess media advertisements, they trusted "The recommendation of a familiar person" most, department stores were the second highest, and TV advertisement was the third. The statistical differences partly existed depending on demographic characteristics: job, and material status. Identifying the decision making factors on sauce products was needed as further study.

  • In this paper, a Smart Home Service Robot, McBot II, which performs mess-cleanup function etc. in house, is designed much more optimally than other service robots. It is newly developed in much more practical system than McBot I which we had developed two years ago. One characteristic attribute of mobile platforms equipped with a set of dependent wheels is their omni- directionality and the ability to realize complex translational and rotational trajectories for agile navigation in door. An accurate coordination of steering angle and spinning rate of each wheel is necessary for a consistent motion. This paper develops trajectory controller of 3-wheels omni-directional mobile robot using fuzzy azimuth estimator. A specialized anthropomorphic robot manipulator which can be attached to the housemaid robot McBot II, is developed in this paper. This built-in type manipulator consists of both arms with 4 DOF (Degree of Freedom) each and both hands with 3 DOF each. The robotic arm is optimally designed to satisfy both the minimum mechanical size and the maximum workspace. Minimum mass and length are required for the built-in cooperated-arms system. But that makes the workspace so small. This paper proposes optimal design method to overcome the problem by using neck joint to move the arms horizontally forward/backward and waist joint to move them vertically up/down. The robotic hand, which has two fingers and a thumb, is also optimally designed in task-based concept. Finally, the good performance of the developed McBot II is confirmed through live tests of the mess-cleanup task.

  • An autonomous and automatic home mess-cleanup robot is newly developed in this paper. Thus far, vacuum-cleaners have lightened the burden of household chores but the operational labor that vacuum-cleaners entail has been very severe. Recently, a cleaning robot was commercialized to solve but it also was not successful because it still had the problem of mess-cleanup, which pertained to the clean-up of large trash and the arrangement of newspapers, clothes, etc. Hence, we develop a new home mess-cleanup robot (McBot) to completely overcome this problem. The robot needs the capability for agile navigation and a novel manipulation system for mess-cleanup. The autonomous navigational system has to be controlled for the full scanning of the living room and for the precise tracking of the desired path. It must be also be able to recognize the absolute position and orientation of itself and to distinguish the messed object that is to be cleaned up from obstacles that should merely be avoided. The manipulator, which is not needed in a vacuum-cleaning robot, has the functions of distinguishing the large trash that is to be cleaned from the messed objects that are to be arranged. It needs to use its discretion with regard to the form of the messed objects and to properly carry these objects to the destination. In particular, in this paper, we describe our approach for achieving accurate localization using RFID for home mess-cleanup robots. Finally, the effectiveness of the developed McBot is confirmed through live tests of the mess-cleanup task.

  • This study investigates and analyzes the diversity of menu in military meal services that are recognized by the soldiers who are familar with meal services and, suggest the implications on the results of the analysis. For the ranks of respondents in terms of demographic features, the sergeants were 43.2%(186), the corporals were 29.7%(128). It was identified that the diversity of menu had significant influences as 57.5%. Thus, for the satisfaction on the kitchen and mess hall service, the sanitary condition was the most considerable factor as 41.6%. Next, water supply facilities, sewer hygiene and towels in washstaynds were the issues to be considered more. In conclusion, this study was limited only to the air soldiers in Chungcheon. Then, the future study needs to expand the samples more than this study to apply the results to the entire army. Moreover, the study could not be actively performed because of the particularity of the army. Consequently, it is required to make these kinds of researches dynamically performed like for any other meal service industries.

The mechanical design and the basic control of McBot II, which performs mess-cleanup function etc. in house, is actually focused in this paper. McBot II is mechanically modeled in the same method that the human works in door by using the waist and the hands. The big-ranged vertical lift and the shoulder joints to be able to forward move are mechanically designed for the operating function as the human's waist when the robot works. The mobility of McBot II is designed in the holonomic mobile robot for the collision avoidance of obstacle and the high speed navigation on the small area in door. Finally, good performance of McBot II, which has been optimally desinged, is confirmed through the experimental results for the control of the robotic body, mobility, arms and hands in this paper.

  • Popliteal artery injury in blunt trauma of knee joint is not common but poses high rate of amputation due to anatomical characteristics or delayed diagnosis and treatment. The aim of the present study is to review the authors' experiences with this condition and identify factors contributing to disability. We reviewed 7 cases of popliteal artery injury in trauma around knee. Injury mechanism, type of vessel damage, associated injuries, mangled extremity severity scores (MESS), ischemic time and additional treatments were analyzed. Tibial fracture, distal femoral fracture and serious soft tissue defect were combined. Mean MESS was 9.9 point and mean time of revascularization was 7.1 hours. Transfemoral amputation was performed in 2 cases due to vascular insufficiency and devastating infection, and 4 patients were able to walk without any support at the last follow up. Age, the severity of soft tissue injury, ischemic time and MESS are thought to be related to prognosis, and young patients with short ischemic time show best results, but authors experienced one exceptional case. We have to consider multiple factors related to the prognosis in popliteal artery injury with fractures around knee, and careful decision is needed regarding to early amputation.
