Purpose: The purpose of this study was to examine the effects of a cognitive behavioral stress management program on diabetic self-care and glycemic control with type 2 diabetic patients. Methods: Thirty three diabetic patients who were older than 40 were recruited from a public health center and conveniently assigned into both experimental(n=16) and control groups(n=17). Participants in the experimental group had attended the weekly cognitive behavioral program for 8 weeks. Data were collected from June 2005 to August 2006 and analyzed by independent t-test using the SPSS WIN program. Results: After an 8 week intervention, participants in the experimental group reported on increasement of diabetic self-care behaviors and an increasement of blood glucose levels, which were significantly different from those in the control group. Conclusion: On the basis of those findings, we concluded that the cognitive behavioral stress management program has positive effects on diabetic self-care and glycemic control for the patients with DM. Further research is needed to identify the long-term effects of the cognitive behavioral program.

Annual average precipitation of Korea is 1,277 mm and around 2/3 of annual precipitation and 74 % of available water resources occurred during monsoon period. In recent years, many agricultural reservoirs have been heightened to increase flood control capacity, reduce flooding damage at downstream areas, and provide sustainable environmental flow during drought period. Thus in this study, the flood control effects of heightening of reservoir banks were simulated with HEC-ResSim and HEC-RAS models. These modes were applied to Bonghak reservoir and it was found that flood control effects were 3~4.5 % with 7 -m heightening. Also, with proper operation (1 m lower of full water level) of reservoir right before the monsoon period, flooding at downstream could be prevented even with design storm of 80 -year recurrence interval. As shown in this study, heightening of agricultural reservoir provides positive effects in flood control and flood damage reduction.

Objective: The aim of this study is to investigate visual feedback effects and human performance in the foot mouse control. Background: Generally, computer mouse tasks are controlled by visual feedback. In order to understand the characteristics of a foot mouse control, it is important to investigate the patterns of visual feedback involved in foot-mouse control tasks. Human performance of foot mouse control is also an important factor to understand the foot mouse control. Method: Three types of mouse control were determined to investigate visual feedback effects and human performance in the foot mouse control. Visual feedback effects in the foot mouse control were compared with those of a typical hand mouse. The cursor movement speed and mental workload were measured in the three types of tasks and two types of mouses. Results: Mouse control tasks with an element of homing-in to the target were more quickly performed by the hand mouse than the foot mouse. Mental workload was also higher in the foot mouse than the hand mouse. However, in the steering movement, human performance of the foot mouse control was not lower than that of the hand mouse control. Visual feedback in the foot mouse control was less required than in the hand mouse control. Conclusion: The foot mouse was not efficient in the most mouse control tasks, compared to the hand mouse. However, the foot mouse was efficient in the steering movement, moving a cursor within a path with lateral constraints. Application: The results of this study might help to develop the foot mouse.

This study examined whether parental psychological control influences adolescents' depressive feelings through personality features of dependency and self-criticism. Participants were 315 high school students (M=16 years) who completed questionnaires tapping two types of parental psychological control and student personality and depressive symptoms. Both girls and boys perceived equal levels of maternal and paternal separation-anxious psychological control. Boys perceived higher achievement- oriented psychological control of fathers than mothers; girls perceived equal levels of maternal and paternal achievement-oriented control. Structural relations between types of psychological control, personality features, and depressive symptoms were equivalent for both mothers and fathers and for both boys and girls. Results confirmed that separation-anxious and achievement-oriented control have negative effects on adolescents' adjustment through differential pathways; dependency and self-criticism, respectively.

In Advanced Vehicle Control System(AVCS), Autonomous Intelligent Cruise Control(AICC) is generally understood to be a system that can be achieved in the near future without the demanding infrastructure components and technoloties. AICC is an automatic vehicle following system with no human engagement in the longitudinal vehicle direction. This paper presents a fuzzy control algorithm to develop the AICC system. The control performance was studied information of vehicles using computer simulations. The most improtant aspects of the work reported here are the adoption of the fuzzy adaptive control law, and the use of filtering concept to reduce the slinky effects that may appear in a formation of vehicles equipped with AICC systems. The simulation results demonstrate the effectiveness of the fuzzy adaptive AICC system and its beneficial effects on traffic flow.

The implementation of a robust $H_{\infty}$ Control, which is numerically efficient for uncertain nonlinear dynamics, on longitudinal and lateral autopilots is realised for a quarter scale Piper J3-Cub model accepted as an unmanned aerial vehicle (UAV) under the condition of sensor noise and disturbance effects. The stability and control coefficients of the UAV are evaluated through XFLR5 software, which utilises a vortex lattice method at a predefined flight condition. After that, the longitudinal trim point is computed, and the linearization process is performed at this trim point. The "${\mu}$-Synthesis"-based robust $H_{\infty}$ control algorithm for roll, pitch and yaw displacement autopilots are developed for both longitudinal and lateral linearised nonlinear dynamics. Controller performances, closed-loop frequency responses, nominal and perturbed system responses are obtained under the conditions of disturbance and sensor noise. The simulation results indicate that the proposed control scheme achieves robust performance and guarantees stability under exogenous disturbance and measurement noise effects and model uncertainty.

Purpose: This study was conducted to examine the effects of simulation-based infection control training on the ICU nurses' perception, clinical performance, and self-efficacy of infection control. Methods: Thirty-eight nurses were assigned into two groups using a career stratified randomization. In the experimental group, the subjects received a simulation-based infection control training, whereas the control group participated in a conventional lecture-based training. Two weeks after the completion of the training sessions, the participants were evaluated for perception, clinical performance, and self-efficacy regarding the infection control. Results: The experimental group that received simulation-based infection control training showed an improvement in perceiving the infection control compared to that of the control group, but the difference was not statistically significant. In terms of the clinical performance, the experimental group and the control group scored $26.05{\pm}3.22$ and $18.53{\pm}3.37$ points respectively, demonstrating a statistical significance (p<.001). There was no significant difference between the two groups in regards to the self-efficacy. Conclusion: The developed simulation-based infection control training showed positive effects in improving clinical performance of infection control over conventional lecture-based training, confirming that a simulation-based training is an effective method in advancing the practical performance of ICU nurses.

This study examined the effects of parental psychological control, dysfunctional perfectionism, and self-conscious emotions on depression in adolescents. The sample consisted of 471 adolescents (212 boys, 259 girls) attending high schools in Seoul. The results from Structural Equation Modeling indicated that dysfunctional perfectionism and self-conscious emotions mediated the impact of parental psychological control on depression only in the mother-daughter relationship, such that with mothers' greater psychological control, girls experienced higher levels of dysfunctional perfectionism and self-conscious emotions, and reported higher depression scores. Similarly, dysfunctional perfectionism functioned as a mediator in the association between parental psychological control and adolescent depression. This tends to support findings from previous studies emphasizing the importance of same sex parent-adolescent relationships. Dysfunctional perfectionism also had the largest direct effect of all variables analyzed on depression. Parental psychological control did not show statistically significant effects on self-conscious emotions for either boys or girls. These findings suggest that interventions designed to promote adolescents' mental well-being should focus on parenting of the same sex parent as well as adolescent cognitive characteristics.
