  • When people write a character with a pen stably, proper compliance planning is necessary. In this paper, after investigating the property of character writing task, we propose a fundamental grasp model for character writing and also analyze compliance characteristics for effective character writing using multi-fingered hands. For this, the general stiffness relation of multi-fingered hand is firstly described. Next, we investigate the grasp configurations for grasping a pen and then, we analyze the conditions of the specified stiffness matrix in the operational space to successfully and more effectively achieve the given character writing task. Through the analysis, an effective grasp modeling for successful character writing is shown. And also, we conclude that the operational compliance characteristics should be properly planned for character writing, stably and precisely.

  • In this paper, a simple idea is proposed to change the compliance center of the Remote Center Compliance (RCC) by adjusting the elasticity of the Elastomer Shear Pad (ESP). To vary the elasticity of the ESP, a hole is made in the ESP along its stiffness axis, and a stiffness adjusting rod (SAR) is inserted into the hole. By adjusting the insertion depth of the rod, lateral stiffness of the ESP can be varied, and the compliance center of the VRCC can be controlled accordingly. To verify the effectiveness of the proposed idea, a prototype VRCC is designed and, the position of the compliance center with various lengths of the inserted rod are measured.

  • In this paper, the design result of robotic tools and the development of robot control system for chemical coupler assembly are presented. This research aims to eliminate the risk of chemicals exposed to human operators by developing the robotic tools and robot automation system for chemical tank lorry unloading that were done manually. Due to tight tolerance between couplers, even small pose error may result in very large internal force. In order to resolve the problem, the 6-axis compliance device is employed, which can provide not only enough compliance between couplers but also F/T sensing. The 6-axis compliance device having large force and moment capacity is designed. A simple linear gripper with rack-and-pinion is designed to grasp two sizes of couplers. The proposed robot automation system consists of 6-DOF collaborative robot with offset wrist, 6-axis compliance device with F/T sensing, linear gripper, and two robot visions.

  • As the tasks of robots become more diverse, some complicated tasks have come to require force and position hybrid control. A compliant device can be used to control force and position simultaneously by separating the twist of the robot's end effector from the twist of compliance and freedom by using stiffness mapping of the compliant device. The development of a fuzzy gain scheduling scheme of control for a robot with a compliant device is described in this paper. Fuzzy rules and reasoning are performed on-line to determine the gain of twists based on wrench error and twist error and twist of compliance and twist of freedom ratio. Simulation results demonstrate that better control performance can be achieved in comparison with constant gain control.

  • Purpose - The purpose of this research is to investigate the effect of ex ante governance mechanisms that can be exercised by franchisers on franchise contract compliance and various relationship outcomes. There are many previous studies on control mechanisms in inter-firm relationship, however, most studies focus on ex post governance mechanisms and identify the effects of behavior control and outcome control on performances. Based on transaction cost theory and agency theory, this study defines the ex ante governance mechanisms of franchisers as contractual completeness and extra contractual incentives. The author have examined the two ex ante control mechanisms on contract compliance, recontract intention, multi-shop running intention and opportunistic behaviors of franchisee. Research design, data, and methodology - In this study, 137 questionnaires of food and beverage franchise stores were collected through a specialized research company. The reliability and validity of the variables were analyzed using SPSS 18.0 and AMOS 18.0 programs and hypotheses were verified through the structural equation modeling. Results - As a result of hypothesis testing, contractual completeness and extra contractual incentives have a positive effect on the contract compliance of the franchisee. It is shown that franchisee's contract compliance has a positive effect on recontract intention and multi-shop running intention and has a negative effect on opportunistic behaviors. Conclusions - This study examines the ex ante governance mechanisms such as contractual completeness and extra contractual incentives, which is relatively rare compared to ex post governance mechanism in B2B relationship. According to the results of this research, these two tools can be used as ex ante control mechanisms for franchise headquarters to use their franchisees. In addition, franchisee's contract compliance affects various relationship outcomes between franchisor and franchisees.

  • Purpose: This study was to evaluate the effects of a physical activity reinforcement program on exercise compliance, depression, and anxiety in continuous ambulatory peritoneal dialysis(CAPD) patients. Method: A nonequivalent control group with a pre-post test was designed. Data collection was done from December, 2002 to June, 2003 at a hoapital. The degree of depression and anxiety of the patients was assessed by the score of SCL-90-R, and exercise compliance was measured by exercise period, frequency, time and intensity. The experimental group was composed of 19 participants who were educated based on an exercise education protocol and carried out walking exercises two to four times a week after hearing verbal persuasion biweekly through the telephone or a face-to-face interview for 12 weeks, while 17 participants in control group received no intervention. Result: 1. The experimental group showed significant improvement in self-efficacy of exercise compliance (U=79.00, p=.01), exercise period ($x^2$=20.84, p=.00), exercise frequency ($x^2$=9.03, p=.0l), exercise time ($x^2$=9.03, p=.0l) and exercise intensity ($x^2$=11.09, p=.00) compared to those of the control group. 2. The experimental group showed a lower depression score (U=84.50, p=.01) than the results of the control group. 3. However, there were no changes in anxiety level compared to the control group. Conclusion: The physical activity reinforcement program was found to have an effect on exercise compliance and the depression score of CAPD patients. The results provided evidence for the importance of physical activity and verbal persuasion in CAPD patients.

  • On the stage of an international trade with well-developed transportation, communication system and proliferation of free trade, global companies who are eager to sustain business growth by cutting cost and pioneering new market are facing a new challenge named "Global Compliance" of business transparency, export and import regulations, and potential international business environment. The purpose of a global compliance is to monitor and regulate a company's trade activities to reduce the risk of transactions that might violate relevant countries' laws, regulations, or standards. After the 911, for strengthening the non-proliferation of the export control goods, UNSCR1540(United Nations Security Council Resolution 1540(2004)) was declared in order to enforce the members to adopt the rules in the resolution into their national laws and regulations. Companies does not realized that they need to get rid of the risks because they underestimate the importance of international security, caused by their careless management. That is why currently the export control program is not fully observed by the most. Lack of awareness for the export control and the poor system of each members could be the reason for this unstable operating status. With this background, this thesis will study on the meaning of export control, schemes for companies to recognize its importance and governmental guideline to support global companies.

  • = ABSTRACT = Objectives : Incheon metropolitan city has set a model program of community partnership for hypertensive or diabetic patients detection and follow-up since 2005. This study examines the effects of the model on the compliance and the control of blood pressure or blood sugar level Methods : Telephone-surveys were done for 140 persons selected from 408 patients who were detected newly as hypertensive or diabetic patients at Gangwha-Gun and Seo-Gu in Incheon between January 1st and August 31th in 2006, and finally completed in 110 patients(78.6%). Survey questionnaires included socio-demographic(age, gender, and educational level), health behavioral (smoking, drinking, physical activity, and diet), and therapy-related (registration state, compliance, blood pressure or blood sugar control) variables. Odds ratio and 95% CI were derived from logistic regression model. Results : Registered group exhibited high compliance and well managed blood pressure or blood sugar level. The odds ratio of registration were 5.55(95% CI:1.83~16.89) for compliance and 3.78(95% CI:1.43~9.99) for blood pressure or blood sugar control after adjusting for age, gender, disease, and area Conclusions : It is independently related to compliance and blood pressure or blood sugar control whether the patient is registered or not. To control hypertension or diabetes mellitus in terms of compliance and control state, a community-based registration program through community partnership could be a powerful tool.

  • Due to the irregularity of walking ground and the inaccuracy in trajectory control of a leg, the mechanical shock and slip on the ground can be caused in the landing and supporting legs of a walkin g robot, and the robot may lose walking stability. Especially in a jointed-leg type walking robot, those problems are much more severe than in the pantograph type since the leg-weight of the jointed-leg type walking robot is relatively heavier than that of the pantograph type in general. In order to secure the walking stability for the jointed-leg type quadrupedal robot under development in KIST(Korea Institute of Science and Technology), a balancing algorithm consisting of the leg compliance control and the body posture control is implemented in this paper, and the effectiveness of the algorithm is verified through experiments.
