  • This paper represents the study of an effective self-tuning PID control for a robot manipulator to track a reference trajectory in spite of the presence of nonlinearities and parameters uncertainties in robot dynamic models. In this control scheme, an error model of the manipulator is established, for the first time, by difference between joint reference trajectory and tracked trajectory. It's model Parameters are estimated by the recursive least-square identification algorithm, and classical controller parameters are determined by pole placement method. A computer simulation study was conducted to demonstrate performance of the proposed self-tuning PID control in joint-based coordinates for a robot with payload.

  • Purpose: The purpose of this study was to explore the subjective opinions related to NVP experience in woman. Method: The research method used was Q-methodology. The statement of self-reference was derived from face to face interviews with 10 womans. Statement were categorized by researcher according to semantics. Twenty-seven of the self reference statement from categories of the Q-population were selected. Twenty-five of pregnant womans were selected by consideration of diversity in sociodemographic background. Based on a 1 to 9 point scale, the selected pregnant womans were made to participate in. Q-sorting. Analysis of Q-type was obtained by use of the QUANAL program. Result: There are three type of NVP experience of Korean womans. The first type focused on family support relate to NVP coping. The second type focused on physical self regulation related to NVP coping. The third type focused on actual strategy related to NVP coping. Conclusion: It is suggested that the results of this study may contribute to the development strategies for the purpose of decreasing the incidence of NVP.

  • A self-regulatory community fisheries management program in Korea is designed to enhance fisheries resources, to protect fishing grounds of self-regulatory communities, and to manage their fisheries resources by their own regulations and knowledge. This study explored an applicable ecosystem-based management plan based on the scientific investigation and analysis. This study suggested objectives, indicators and reference points of the ecosystem-based resource management system which are applicable to selfregulatory community fisheries. The objectives of the management system are to maintain sustainable fisheries production, to maintain optimum fishing intensity, to reduce by-catch, to conserve spawning ground and habitat, to maintain optimum habitat environment, to increase/maintain abundance of prey species, to increase/maintain stock biomass, and to conduct stock enhancement on the basis of scientific assessment. The improved methods for the assessment and management are introduced by demonstrating a self-regulatory fishery which targets on hen clam in Dong-li fishing village in Busan.

  • The use of lubrication oil is of many purposes and one among them is to drive the engine mounted on a ship. Hence the supply of clean lubrication oil is important. And an oil purifier is one of key components in marine diesel engines. At present, the element type full-flow oil filter has been widely used for cleaning the engine oil. The self-driven centrifugal oil purifier is a device which is used to remove the impurities in lubrication oil using a jet flow. The flow characteristics and the physical behaviors of particles in this self-driven oil purifier were investigated numerically and the filtration efficiencies were evaluated. For calculations, a Computational Fluid Dynamics method is used and the Shear Stress Transport turbulence model has been adopted. The Multi Frames of Reference method is used to consider the rotating effect of the flows. The influence of centrifugal forcehas been numerically investigatedto improve filtration efficiency of tiny particles. As a result of this research, it was found that the particle filtration efficiency using the only center axis rotating and outer wall rotating system are higher than that of the fully rotating system in the self-driven oil purifier.

  • The purposes of this study are to segment female X-generation consumers by the types of conspicuous clothing consumption behavior and to examine the differences among consumer groups with self-respect, the influence of reference group, materialism, and demographic characteristics. A questionnaire was developed and 18-35 year female living in Seoul responded to a questionnaire. The 499 subjects were analyzed. The results can be summarized as follows : Respondents divided into five consumption groups. such as non-conspicuous clothing consumption group, fashion-oriented clothing consumption group, well-known brand and expensive clothing consumption group, imitation c1othing in well-known brand consumption group and imported clothing consumption group. Imitation clothing in well-known brand consumption group. Imported clothing consumption group are the highest average mark in education and family income. Non-conspicuous clothing consumption group is the lowest average mark in education and family Income of five groups. Well-known brand & expensive clothing consumption group is the highest average mark in the influence of reference group, materialism of five groups. Non-conspicuous clothing consumption group is the lowist average mark in the influence of reference group. materialism of five groups.

  • Silibinin(silybin) is the active component of silymarin from Silybum marianum and has hepato-protective effect. It is water-insoluble and has low bioavailability. To improve its bioavailability, self-micro-emulsifying drug delivery system (SMEDDS) has been developed by Hanmi Pharmaceutical Company (Silyma $n^{R}$ 140 soft capsule). In this study, the pharmacokinetic profiles of Silyma $n^{R}$ were examined and compared it with a reference preparation, L Caps140 of B Pharmaceutical Company. This study was approved by Yonsei University Severance Hospital IRB(approval No. CR0004) and followed the bioequivalence test guideline of Korean FDA. Eighteen healthy adult volunteers were allocated based on 2$\times$2 Latin square cross-over design. They were given 2 capsules (each contains silymarin 140 mg (60 mg as silibinin)) of either drug at each period and crossed over after a week of drug-free washout period. Blood concentration of silibinin was measured by HPLC. The $C_{max}$ and AUC of the Silyma $n^{R}$ were 1542.0 $\pm$ 402.7 ng/ml and 3323.3 $\pm$ 824.7 ng.h/ml, respectively, and were significantly higher than those of reference preparation. The Tmax was 0.8 $\pm$ 0.3 h and significantly shorter than reference preparation. The $K_{e}$ and $T_{1}$2/ of both drugs were comparable. Percent differences in means against reference preparation were +88.3% for AUC, +222.6% for $C_{max}$, and -61.1% for $T_{max}$./.>././.>./.

  • Face recognition technology has lately attracted considerable attention because of its non-intrusiveness, usability and applicability. Related companies insist that their commercial products show the recognition rates more than 95% according to their self-testing. But, the rates cannot be admitted as official recognition rates. So, performance evaluation methods and tools are necessary to objectively measure the accuracy and performance of face recognition systems. In this paper, I propose a reference model for biometrics recognition evaluation tools, and implement an evaluation tool for the face recognition system based on the proposed reference model.
