  • Purpose: The effects of telephone intervention on self-care practices and quality of life for gynecological cancer patients under chemotherapy was investigated. Methods: A non-equivalent control group pre-test post-test quasi-experimental design was used. The subjects were women cancer patients who had received less than two chemotherapy sessions at C university hospital of Chonnam province(26 in the experimental group: 25 in the control group). The patient's self-care practices(Na & Lee, 1999; Jang, 2004) and quality of life(Lee & Jo, 1997) were measured three times. using a questionnaire. The data was analyzed by Repeated Measures ANOVA, the Friedman test, and the Mann-Whitney test using the SPSS window version 12.0 program. Results: This study showed that the score of self-care practices and quality of life for the experimental group under telephone counseling were higher than those of the control group. Conclusion: This study revealed that a telephone intervention as supportive nursing care for women cancer patients under going chemotherapy was effective for self-care practices and qualify of life during the recovery period. Futhermore, this study also suggests that telephone counseling can serve as a continuing nursing supportive intervention for women cancer patients for the upcoming stages of further chemotherapy.

  • Feedrate is one of the factors that have the significant effects on the productivity, qualify and tool life in the cutting mechanism as well as cutting velocity, depth of cut and width of cut. In this study, in order to realize the high-efficient machining, a new feedrate optimization method is proposed based on the concept that the optimum feedrate can be derived from the allowable cutting power since the cutting power can be predicted from the cutting parameters as feedrate, depth of cut, width of cut, chip thickness, engagement angle, rake angle, specific cutting force and so on. Tool paths are extracted from the original NC program via the reverse post-processing process and converted into the infinitesimal tool paths via the interpolation process. And the novel NC program is reconstructed by optimizing the feedrate of infinitesimal tool paths. Especially, the fast feedrate optimization is realized by using the Boolean operation based on the Goldfeather CSG rendering algorithm, and the simulation results reveal the availability of the proposed optimization method dramatically reducing the cutting time and/or the optimization time. As a result, the proposed optimization method will go far toward improving the productivity and qualify.

  • At present, company has to produce a product that consumer like with a competitive price, a good quality, and a fitting time to supply. Process control and qualify control are very important to supply with a product uniformly and inexpensively In this paper, the characteristic of product quality is monitored by control chart during the machining process and construction of quality control cycle is considered to divide into two types in this case that different assignable causes lead to shifts having different magnitudes. Then we are intended to find a process shift magnitude which has economical quality cost policy and are considered to quality cost functions to find a process shift magnitude. Those costs are categorized into the well-known categories of prevention, appraisal, and internal failure and external failure. This paper ends with numerical examples that demonstrate the usefulness of the model.

  • An optimal control technique designed for simultaneous tracking and quality control for batch processes. The proposed technique is designed by transforming quadratic-criterion based iterative learning control(Q-ILC) into linear quadratic control problem. For real-time quality inferential control, the quality is modeled by linear combination of control input around target qualify and then the relationship between quality and control input can be transformed into time-varying linear state space model. With this state space model, the real-time quality inferential control can be incorporated to LQ control Problem. As a consequence, both the quality variable as well as other controlled variables can progressively reduce their control error as the batch number increases while rejecting real-time disturbances, and finally reach the best achievable states dictated by a quadratic criterion even in case that there is significant model error Also the computational burden is much reduced since the most computation is calculated in off-line. The Proposed control technique is applied to a semi-batch reactor model where series-parallelreactions take place.

  • While the pavement design is based on mechanical property such dynamic elastic modulus, the quality of highway subgrade during construction is controled by the optimum moisture content(OMC) and maximum dry density(${\gamma}$$\_$dmax/). However, since the quality control based on the OMC and maximum dry density does not consider the mechanical characteristics, there is a conceptional gap between design and PMS(pavement management system). Therefore, it is necessary to develope a new qualify control system using mechanical property for highway construction in more rational way. To achieve this goal, it is planned to perform various laboratory tests to collect mechanical properties of subgrade soil samples from several highway construction sites and to propose the relationship between dry unit weight (or OMC) and mechanical parameters. In this paper, the experimental data so far obtained are presented and analyzed. In addition, further research plan is presented and discussed.
