Design aspects of a bearing casing system of a power plant are mainly focused on the strength and weight of itself to have a more stable system. Since the rotor speed often passes through the critical speed region when the operation begins, the relation between the rotating frequency of the rotor and natural frequency of the casing is very important for a prevention of resonance. However, harmonic components above the rotating frequency have often been overlooked the design for the resonance avoidance. In this paper, it is revealed that resonance vibration is generated when the natural frequency of a bearing casing is close to the one of harmonics of basic rotating frequency(1x), and as a consequence, sensing qualify of seismoprobes attached to the bearing casing structure can be seriously damaged. In order to reduce the resonance vibration, some stiffeners are added to the casing structures. Significant reduction in the magnitude of vibration corresponding to 2x harmonic of basic rotating frequency is observed from both FE analysis and experiment.

The purpose of this study is to correctly understand the shaping process of Mongolian women's costumes, which had close connection with Korean costumes. 'Nomadic' factors of Mongol costumes are trousers and jacket, with deel(袍) pleated in the waistline for horse riding, and knee-covering narrow-sleeved long dress for men and women alike for protection against the cold. However, Married women wore bogthag(gogo: ) containing symbols derived from nomadic way of life. 'Foreign' factors are divided into two kinds; foreign culture applied to Mongolian costumes(woven stuff, Koryo style), and transformation in costumes to adjust to the environmental alteration owing to extended territory(pigap(比甲), Jacket and skirt), the last of which served as the chief distinction between nomadic and Y an fashions. 'Religious' factors are unique patterns and colors while retaining their symbolism. Some aspects(mongke tengri or eternal sky) of Shamanism is reflected in avoidance of washing, while positive effect of Lamanism is evidenced in yellow cosmetic applied on the forehead and 16 sky devil dance clothes.dance clothes.

The author reviewed psychosomatic aspects of bronchial asthma including psychological aspect of bronchial asthma, patients' reactions to illness, reactions of therapists and families, effect of bronchial asthma on mental function, psychotherapy and pharmacotherapy. The therapists' understanding of these aspects is likely to be helpful in their predicting and understanding the type of adaptation their asthmatic patients are making to their illness. Thus, the therapists need to recognize the asthmatics' psychological needs. They also should understand the vicious cycle of anxiety-hyperventilation-panic-fear-avoidance in patients with bronchial asthma and should try to break this cycle. To make it possible, the patients' panic-fear level should be assessed and sometimes it will require psychiatrists' advice. On the other hand, the asthmatics should be trained to be shaped to relate subjective feeling of pulmonary function with objective pulmonary measures, which will enable these patients to perceive their early symptoms and to cope with asthma attack effectively. The therapists need to pay attention to their emotion during evaluation and treatment of patients with bronchial asthma, because they are less likely to perceive stress and express their emotion.

In this study, we ran a collage fashion illustration program. We used in depth personal interviews to find if there are any change in self-image by psychologically analyzing the features of self-images expressed in the pieces of fashion illustration. The total number of objects were five females students majoring in fashion design in Busan. They were hoping to have a psychology consultation to resolve their concerns about the future, family affairs, appearance, and careers. Collage fashion illustration program was used as a experimental tool to find the psychological features shown in the formats and content of collage fashion illustration. We then figure out how pre and post diagnosis were different from each other in terms of ego-identity and DAP. As a result, the formats in collage fashion illustration are related to the self images such as psychological energy, incompetency, suppression, and tendency of self-centered. Also, the contents of the fashion expression are related to the self-images such as dependency, avoidance, wariness, and self-regard. All of the participants have improved self-regard and active action due to improvements in subjectivity, initiative, and goal orientation. Therefore, they could change from pessimistic self-images to optimistic ones.

Technologies for preventing contaminants deposition are a key issue in a modern duct system. When particulate matters deposit inside the exhaust pipes, which are widely used in the Urea-SCR system to reduce $NO_x$ emission from heavy duty diesel engines, many problems arise associated with increased flow resistance and corrosion. Therefore, the development of the urea deposition avoidance technologies is being treated as an important issue of the Urea-SCR system. An analytical study was carried out to investigate the effects of the wall flow around the mixer with the variation of the mixer housing surrounding and supporting the mixer, which is designed to increase the wall flow and then to reduce droplet deposition. The housing angles and the position of the mixer were changed：angles of $0^{\circ}$, $1^{\circ}$, $2^{\circ}$, and $3^{\circ}$, and mixer positions of 0 L, 0.5 L, and 1 L. The axial velocity distributions, maximum velocity, the half-width, and momentum distribution of the wall flow were investigated to examine the effect of the mixer-housing assembly geometry.

Background: This study investigated the effects of pelvic floor stabilization exercise of pain, disfunction, psychosocial, electromyography (EMG) activity on the lower back pain with postpartum. Methods: The study included 20 postpartum women who were randomly assigned to a sling exercise group (SEG, n=10) or a general physical therapy group (GPTG, n=10). Outcomes were assessed using to lower back pain with postpartum the quadruple visual analogue scale (QVAS), the Korean version of the Oswestry disability index (KODI), the fear avoidance belief questionnaire (FABQ), the inventory of functional status after childbirth (IFSAC), the edinburgh postnatal depression scale-Korean (EPDS-K), and trunk muscle activity before and after a 4-week exercise intervention. Statistical analysis were performed using a mean, standard deviation, crosstab test, paired t-test, independent t-test. Kolmogorove-Smirnov test was used for test of normality. Results: Compared to the GPTG, the SEG showed significant improvement in the QVAS, KODI, FABQ, IFSAC, and EPDK-K scores (p<.05) after 4 weeks. Conclusion: Postpartum pelvic strengthening exercise proved to have a positive effect.

Several aspects including physical development, reflex acquistion, neuromotor development and learning behavior at Y water maze were compared at the progeny of rats fed low 91.2mg/kg diet) or adequate leves(22mg/kg diet 0 of pyridoxine during growth, gestation, lactation, and adult period. Physical development and development of reflexes (righting reflex, cliff avoidance, negative geotaxis, palmar grasp, and startle reflex to sound) appeared different between control and deficient groups but not significantly. At the 2nd week, rats spent more time in supported standing during 6 minute period was longer in the control then the deficient groups. In the Y-water maze position reversal test, learning ability as judged by the number of errors was not different among three groups, but the rats in supplemented group(DC) reached the escape platform in significantly shorter time than the other two groups, which may suggest their emotional instability. In the visual discrimination test, the performance of rats from the supplemented group had the lower errors than the other groups on the early test days. but as the testing period progressed, the performance of rats in the supplemented group became inferior to those of the control and deficient groups. The performance of control group became superior to that of the deficient group.

This study examined the effect of parents' neglect behavior and children's irrational beliefs on children's anger expression style. The participants were 379 5th and 6th grade elementary school children. The major findings were as follows. Children tended to perceive higher levels of their parents' cognitive and emotional neglect than physical and home environmental neglect. Boys perceived higher levels of their parents' physical, supervisory and home environmental neglect than girls, and girls showed higher level of excessively self-expecting belief than boys. There were statistically significant correlations between the parents' neglect behavior, their child's irrational beliefs and anger expression style. A regression analysis showed that parents' physical and cognitive neglect were predictors of children's anger control. Children's excessive apprehension and avoidance beliefs were the best predictors of children's anger-in, while children's deterministic belief was the best predictor of children's anger-out. Parents' physical neglect behavior appeared to be powerful predictor.

Purpose： This study examined the effects of cognitive-behavioral therapy on problem-solving ability and dysfunctional attitudes in undergraduate students. Method： This study was conducted between September 2004 and May 2005. The subjects consisted of 23 undergraduate students. The experimental group (n=13) participated in a cognitive-behavioral therapy that consist of 8 session over an 8-week period. The control group (n=10) participated in a reality therapy that also consisted of 8 sessions over an 8-week period. Problem-solving ability and dysfunctional attitudes were measured for all subjects before and after therapy. These data were analyzed by unpaired t-test and t-test with the SAS program. Results： Following cognitive-behavioral therapy, the experimental group experienced a significant decrease in score of problem-solving ability and in approach-avoidance style (the subscale in the problem-solving ability). There were no changes in these values after the reality therapy in control group. Conclusions： In light of these results, cognitive-behavioral therapy has a positive effect on problem-solving ability in undergraduate students.
