The present study aimed to investigate the effects of kinematic taping therapy on menstrual distress, pain, and $prostaglandinF2{\alpha}$. The experimental subject was a 24 years old woman with the pain of over 5 points on the dysmenorrhea measurement test and no unusual reactions on the taping test. The menstrual distress was measured by the Menstrual Distress Questionnaire (MDQ), and the dysmenorrhea was measured by the Visual Analogue Scale (VAS) before and after the intervention. The prostaglandin $F2{\alpha}(PGF2{\alpha})$ was measured on the first day of menstruation before the intervention and 24 hours after the taping therapy by the blood test. The intervention of kinematic taping was conducted by the instructor of the International Kinematic Taping Academy, and the taping was applied to the lower abdomen and the waist. According to the difference of menstrual distress before and after the intervention, the menstrual distress turned out to be decreased to 96 points after the intervention from the 115 points before the intervention. The dysmenorrhea also reduced 3 points on the VAS from 7 points to 4 points before and after the intervention. The $PGF2{\alpha}$ decreased from $26pg/m{\ell}$ to $20pg/m{\ell}$ before and after the intervention. Besides, the $PGF2{\alpha}$ decreased from $26pg/m{\ell}$ to $20pg/m{\ell}$ before and after the intervention. Results suggest that kinematic taping therapy could be useful to reduce the menstrual distress, pain, and $PGF2{\alpha}$.

Purpose: The purpose of this study was to use an ICF tool in an intervention for anterior cruciate ligament reconstruction (ACLR) patients to examine and evaluate the patients' functional problems, measure the results of the intervention, and present the process of preparing proprioceptive neuromuscular facilitation (PNF) intervention strategies, thereby contributing to changes in and development of relevant future clinical practices. Methods: A PNF rehabilitation exercise program using an ICF tool was applied to ACLR patients five times per week for four weeks. To measure the resulting changes, the ICF evaluation display, the visual analog scale (VAS), the manual muscle test (MMT), the range of motion (ROM) test, the Lysholm knee score (LKS), and the muscle endurance test (MET) were used. Results: After the intervention was applied to the ACLR patients, improvements were achieved in all the tests: ICF evaluation display, VAS, MMT, ROM, LKS, and MET. Conclusion: Utilizing the ICF tool, this study identified functional problems of ACLR patients. When the intervention was applied, physical functions improved, and structural damage was reduced, leading to enhanced levels of functional activities such as postural changes, posture maintenance, gait, movements, and movements between different places. The patients were able to complete the teacher training, which was their goal.

$LaCrO_3$-dispersed Cr alloys for metallic interconnector of solid oxide fuel cell have been studied as function of $LaCrO_3$ content in the range of 5 to 25 vol.% in order to examine the electric conductivity, the oxidation property and the thermal expansion behavior of these alloys. The $LaCrO_3$-dispersed Cr alloys showed high electrical conductivities of $3~5\times10^4$ S/cm at room temperature, and as the $LaCrO_3$content increased the conductivity decreased slightly. During the cyclic oxidation test at $1100^{\circ}C$, the weight change of the Cr alloys decreased with increasing number of oxidation cycle except first cycle, which is attributed to the vaporization of the oxide scale. More addition of the $LaCrO_3$ content reduced also the weight change of the Cr alloys. These mean that the oxide scale formed at the surface of the Cr alloy becomes stable with increasing number of oxidation cycle and$LaCrO_3$ content. The measured thermal expansion of the Cr alloy was well fitted to that of 8 mol% $Y_2O_3$-stabilized $ZrO_2$ electrolyte. These results demonstrate that $LaCrO_3$-dispersed Cr alloy is a useful material for metallic interconnector of solid oxide fuel cell.

Objectives: Executive dysfunction including working memory deficit has been suggested to be one of the major neuropsychological etiologies of attention-deficit hyperactivity disorder (ADHD). The purpose of this study was to investigate the augmentative effects of Cogmed working memory training on the symptoms and neurocognitive functions in medicated children and adolescents with ADHD. Methods: Twenty-five children with ADHD, aged 7 to 19 years, taking ADHD medication participated in this study. The participants were trained for 5 weeks with a commercially available and computerized working memory program ($Cogmed^{(R)}$) without any changes to their medication. The Korean version of the ADHD Rating Scale, Clinical Global Impression Scale, and Comprehensive Attention Test were administered before training and 4 weeks and 7 months after training, respectively. Results: After completing the training, the clinical symptoms and function, rated by the parents and clinician, were improved. In addition, the level of commission errors was significantly reduced in the selective attention (visual/auditory) task, sustained attention to response task, and flanker task. The untrained visuospatial short-term memory and working memory were also improved. These effects were still observed 7 months after the training. Conclusion: Cogmed working memory training can be a promising training option for the additional improvement of the symptoms and deficits in working memory and response inhibition in medicated children with ADHD.

Objectives: This study was aimed to figure out the effect of Onkyung-tang (OKT) on cold hypersensitivity on feet in female patients. Methods: This study was designed to implement multi-center randomized clinical trial in three korean medical hospitals. The female patients who were enrolled in this study were 112 women who suffered from cold hypersensitivity on feet. They were randomly allocated into OKT group or control group in 1:1 ratio. The primary outcome was change in score of visual analogue scale of hypersensitivity on feet, and the secondary outcomes were thermometer of LU4, PC8, ST32, LR3, visual analogue scale of hypersensitivity on hands, result of cold stress test, and score of World Health Organization Quality of Life-BREF. Results: In both group, the VAS of hypersensitivity on feet and hands was decreased while taking the medicine, and the effect of decreasing the VAS continues for the 4 weeks after the end of medication (p<0.001, 0.003, 0.001). In OKT group, the body temperature difference in lower extremity (ST32-LR3) was steadily decreased at every visit and it was statistically significant(p=0.003, <0.001). On the other hand, in control group, the body temperature difference in lower extremity was decreased only while taking the medicine (p<0.001). Conclusions: OKT significantly reduced discomfort coldness on feet in patients, and the effect of treatment was maintained at least for four weeks after medication.

본 논문에서는 기초지반의 강성이 블록식 보강토 옹벽의 거동에 미치는 영향에 대한 내용을 다루었다. 기초지반의 강성이 블록식 보강토 옹벽의 거동에 미치는 근본적인 메카니즘을 고찰하기 위해 보강토 옹벽에 대한 축소모형실험을 수행하였으며 축소모형실험 결과의 타당성을 검토하고 모형실험에서 다룰 수 없었던 다양한 조건을 고려함과 아울러서 현장옹벽 응력수준의 거동을 고찰하기 위해 가상의 현장옹벽에 대해 유한요소해석을 이용한 매개변수 연구를 수행하였다. 모형실험 및 유한요소해석 결과에 의하면 기초지반의 강성이 감소할수록 벽체의 변위는 현저히 증가하며, 이러한 벽체변위 증가 현상은 보강토체 내부변형보다는 보강토체의 강체 거동으로 인해 야기되는 메카니즘을 보이는 것으로 나타나 기초지반에 관련된 문제를 외적안정성의 개념에서 다루고 있는 현 설계기준은 타당한 것으로 나타났다. 본 논문에서는 모형실험 및 유한요소해석 결과를 종합하여 실무적 측면에서의 중요성을 다각적으로 고찰하였다.

The purpose of this study is to investigate the friction characteristics of brake pads according to different ratios of $BaSO_4/CaCO_3$. Four brake pads with different ratios of $BaSO_4/CaCO_3$ were manufactured. The friction characteristics of brake pads were tested using 1/5 reduced scale tester. With increasing of the amount of $BaSO_4$ density and shear strength of brake pads were increased and hardness of brake pads were decreased. In effectiveness, the friction coefficient of brake pad was higher and the stability of friction coefficient was better as the ratio of $BaSO_4$ increased. In fade test, friction coefficient of B3 sample used only $CaCO_3$ was decreased rapidly. B1 sample showed a good noise performance without noise generation. The wear resistance of samples were decreased with increasing of the ratio of $CaCO_3$.

Purpose. With a sample of cognitively impaired nursing home residents and nursing staff, the following were examined 1) the proportion and nature of aggressive behavior, 2) the frequency and types of aggressive behavior, 3) the difference between the residents who demonstrate aggressive behavior and those who do not demonstrate aggressive behavior (age, mental status, functional status, and pain, length of nursing home stay), and 4) nursing staff responses to aggressive behavior by residents. Methods. A cross-sectional descriptive study design was used. Data were collected from cognitively impaired nursing home residents (N=205) and nursing staff (N=60) at two nursing homes using Ryden Aggression Scale I and II, Mini-Mental State Exam, Modified Barthel Index, Verbal Descriptor Scale, and aggressive behavior management questionnaire. Data were analyzed using descriptive statistics including t-test. Results. About $62.9\%$ residents were found to be aggressive and $38.5\%$ were both physically and verbally aggressive. Pushing, making threatening gestures, hitting, slapping, cursing/obscene/vulgar languages, making verbal threats were occurred frequently. Aggressive residents were significantly older, had more cognitive impairment, had more pain, and stayed longer in the nursing home when compared with non-aggressive residents. Considerable proportion of nursing staff responded to aggressive behaviors inadequately. Conclusion. Aggressive behavior among cognitively impaired nursing home residents is prevalent thus needs to be prevented and reduced. Along with environmental modification, educational programs for nursing staff and family caregivers need to be developed and implemented so that they can have extensive knowledge and skills to manage aggressive behaviors.

Objectives : We already know the importance of stability and flexibility on the vertebra. It is important to keep the lumbar lordosis for stability and flexibility. We hope to reduce lower back pain and low extremity pain by changing the angle of the Lumbar Kyphosis through conservative treatment. We have evaluated the effect of conservative treatment with Saamchimbeop Pejeonggyeok by experimenting one patient suffering from Lumbar Kyphosis with lower back pain and low extremity pain. Methods : One patients were diagnosed as Lumbar Kyphosis through X-ray examination. We used conservative treatment, especially Pejeonggyeok Treatment to the patients and measured NRS((Numerical Rating Scale), rating scale for low back pain, low extremity pain and SLR(Straight Leg Raising) test and walking time in whole term of admission, and we also measured flexion, extension angle and lumbar kyphosis using lumbar x-ray lateral view after diganosing by Lumbar Kyphosis. Results and Conclusions : After treating conservative therapy, We figured out that the patient were on the mend, and we found out the angle change in flexion, extension and lumbar Kyphosis. These results suggest that Pejeonggyeok Treatment were effective to improved Lumbar Kyphosis and reduced the low back pain.
