Objectives The purpose of this study is to find out the correlation between Stroop interference and the symptoms of weak children. Methods Questionnaire and performed Stroop interference test were done by 145 patients in OO Oriental Medical Hospital from May to October 2009. 120 patients who were considered as the weak children were divided into two groups: Stroop Interference T score above average group and below average group, and were surveyed again. Results 1. The study showed that age, the highest marked subject and behavior habits correlate to interference score and subjects characteristics. 2. Weak children groups had the highest tendency of having weak heart followed by weak lung spleen, liver, and kidney. Normally, a patient belonged to more than one of the weak children groups. 3. The study showed that a group of children who has weak heart and lung were related to interference score. The group which earned below average interference score had the highest frequency of being children with weak heart group. The group scored above average, however, had the highest chance of being children with weak lung group. 4. The study showed that interference score was related to four out of fifty questions about the weak children symptoms. Plus, related questions were all about the heart weak children symptoms. Conclusions In conclusion, there were significant correlation between interference score and the group consists of children who were weak: more specifically with children with weak heart.

Objectives : As obese children have been increased, the interest in the impact of obesity on growth also have been increased. This study is to examine relations between obesity and skeletal maturity by analyzing body compositions and bone age. Methods : Subjects were composed of 233 children from 6 years to 17 years of age, without any other diseases related to growth, who visited the department of pediatrics, OO oriental medicine hospital and measured their body composition (body mass index, body fat ratio, fitness score) and bone age. Results : 1. As body mass index was increased, the skeletal maturity significantly was also increased. 2. As the mean of bone maturity was increased, the BMI was increased from the underweight type to the normal type to the overweight type; the bone maturity was increased as the fat ratio was increased from the normal type to the obese type to the excessively obese type; and the bone maturity was higher in the weak, obese type than the normal type when classified according to the Fitness Score. 3. The bone maturity of the overweight group in the BMI classification and excessively obese group in the fat ratio classification significantly were increased. 4. Skeletal maturity significantly was increased in children who developed secondary sexual character. 5. The significance of obesity causing increase of the skeletal maturity was higher in boys than in girls. 6. Only in the case of children without development of secondary sexual character, obesity caused an significant increases in the skeletal maturity. Conclusions : Obesity could cause the increase of skeletal maturity, and the obesity could affect more to the boys than girls and more to the children than teenagers.

In the process of development the e-learning course at Cyber University, one important factor to be considered for the effective e-learning contents is the User Interface(UI) of the e-Learning content platform. The User Interface is important because the well-designed UI can help students to perform effectively and easily learning activities. Despite the importance of the usability, few attempts have been carried out to design the e-learning contents UI from the usability perspectives. Thus, the purpose of this study is to explore the usability design elements for the e-learning contents UI. For this purpose, a usability evaluation study on the e-learning contents UI of a cyber university at Seoul was conducted. Implications for the improvement of the current e-Learning contents UI was presented.

Purpose: This study aimed to investigate a clinical effect of Coo-Sun activity focusing on improvement of quality of life in female cancer patients. Methods: The subject of study consisted of 5 female cancer patients at the East-West Cancer Center of OO Oriental hospital. The survey methods of this study are Functional Assessment of Cancer Therapy-General (FACT-G) and State-Trait Anxiety Inventory (STAI). Patients performed Coo-Sun activity 6 times a week and filled out FACT-G and STAI questionnaire after every 3 times training. Results: In FACT-G questionnaire, physical well-being and emotional wellbeing was improved significantly after Coo-Sun activity. And change of social/family well-being and functional well-being score were not significant statistically. In STAI questionnaire, STAI1 was improved significantly after Coo-Sun activity. And change of STAI2 score was not significant statistically. Conclusion: After Coo-Sun activity, quality of life (QOL) in female cancer patients was improved and anxiety was decreased. But this study have limitation to prove effects of Coo-Sun activity completely in female cancer patients. So well designed prospective cohort study will be needed to prove its benefits.

Purpose: This study was performed to observe the correlation between Hot flush and pulse wave velocity(PWV), ankle brachial index(ABI) in the Climacteric women. Methods: We studied 63 climacteric women visiting OO hospital from 8th January 2007 to 22nd April 2009. The subjects were categorized in two groups, the hot flush group(37) and normal group(26). For the study, the subjects were selected by excluding the patients who receive treatment affect hot flush or have disease affect arterial states. We assessed PWV and ABI of two groups by Oscillometric method using VS-1000(Form PWV/ABI; Fukuda Denshi, Co., Ltd., Japan). From these results, we studied the correlation between hot flush and PWV/ABI by Wilcoxon Mann Whitney Test. Results: 1. It is shown that hot flush group was no significant correlation with normal group. There is no significant factor among R-PWV, L-PWV, R-ABI, L-ABI. However, L-ABI have shown relatively higher correlation with comparison to the other factors.(p-value<0.05) 2. R-PWV, L-PWV significantly increased in menopause group than in premenopause group though there is no relation to the hot flush. (p-value<0.01) Conclusion: Though the results showed no correlations between Hot flush and PWV/ABI in the Climacteric women, L-ABI showed relatively higher correlation with hot flush than others. R-PWV, L-PWV showed significant correlation between premenopause and menopause.

To investigate the effect of a shaded apodizer on the read-out signal in an optical disc system, we consider the is apodizer in which the amplitude transmittance decreases gradually from the center of pupil toward its edge and the iH apodizer in which the amplitude transmittance increases gradually from the center of pupil toward its edge, using the scalar diffraction theory. We also consider the bump shapes which are a cylindric, a semi-conic, and a conic bump, and bump height which is given by $\lambda/4$ and occurs to the phase change $(\pi)$). The read-out signal of is apodizer increases from S = 0 upto maximum value, and then decreases for increasingly larger values of bOo While the iH apodizer has two maximum values. When an optical disc system has a spherical aberration $(W_{40}=0.5\lambda)$, the maximum read-OUt signal of is apodizer is higher than that of iv apodizer which has no apodizer.odizer.

Purpose: The survival of bone marrow derived stem cell was reported several times. But the survival of adipose tissue derived stem cells(hASCs) was not mentioned on. We studied the adipose tissue derived stem cell's survival and effect on articular cartilage in rabbits. Methods: Osteoarthritis was induced in twenty New Zealand white rabbits by intraarticular injection of monosodium iodoacetate(MIA). After four weeks, hASCs were also injected into the knee joints space without any vehicle, but the control group received phosphate buffered saline only. The histologic grade of articular cartilage was measured in 4 and 8 weeks after the transplantation of hASC and the viability of injected stem cells measured by Fluorescent in situ Hybridization (FISH) examination. Results: After 4 and 8 weeks from hASCs transplantation, histologic grade was not significantly difference between two groups(p>0.05), and the Y chromosome of the transplanted hASCs was not detected in articular cartilage. Conclusion: We found that direct injection of hASC in joint space didn't work on damaged articular cartilage repair.

This study intended to find out the most substantial items in cold and heat pattern identification(CHPI) questionnaire based on usual symptoms through CHPI diagnosis and evaluation by experts. 120 participants, faculties of OO university, filled out CHPI questionnaire based on usual symptoms by the way of self-reporting. Then 2 Korean Medicine doctors independently diagnosed them whether they belonged to cold pattern identification(PI) or heat PI, and scored the result of it. Pearson correlation of 2 experts was 0.649 in cold PI and 0.605 in heat PI. Agreement was 75.8%(Kappa value 0.516) in cold PI and 74.2%(Kappa value 0.465) in heat PI. Pearson correlation of 2 experts was 0.649 in cold PI and 0.605 in heat PI. Agreement between two experts was 75.8%(Kappa value 0.516) in cold PI and 74.2%(Kappa value 0.465) in heat PI. Items of high correlation with experts' evaluation followed next: "do not usually like the cold", "usually like the warm", "usually feel cold" in cold PI and "do not usually like the hot", "usually feel hot", "usually feel burning sensation in the body" in heat PI. We could infer from that facts that experts give weight on 'subjective feeling of cold or heat in participants body' and 'preference on sensation of cold and heat'. We also expect this study to be an epidemiological foundation to disclose correlation between usual CHPI and diseases.

One of the computer application fields which started showing noticeable new growth trends in recent years is the real time communication distributed computing application field. Object -oriented(OO) real time(RT) distributed computing is a form of real-time distributed computing realized with a distributed computer system structured in the form of an object network. In this paper, we describes the application environment as the DHS (distributed high-precision simulation) with TMO structure. The TMO scheme is aimed for enabling a great reduction of the designer's effort in guaranteeing timely service capabilities of distributed computing application systems. It has been formulated from the beginning with the objective of enabling design-time guaranteeing of timely action. In the real time simulation techniques based on TMO object modeling, we have observed several advantages to the TMO structuring scheme. TMO object modeling has a strong traceability between requirement specification and design, cost-effective high-coverage validation, autonomous subsystems, easy maintenance and flexible framework for requirement specification.
