Objectives This study analyzed the correlation between body parameters measured using X-ray and Chuna posture analysis system to determine their clinical value in diagnosing and evaluating skeletomuscular diseases. Methods X-ray and Chuna posture analysis system were performed for 105 patients to measure physical characteristics such as Interacromial angle, Pelvic obliquity angle, Structural leg length discrepancy (SLLD), Midpatella-midtalus angle (MMA) and Q-angle, Anterior head translation (AHT), Anterior superior iliac spine to posterior superior iliac spine angle (ASIS-PSIS angle), Interscapular angle, Scoliotic angle and Cobb's angle. Statistical analysis using statistical analysis techniques and Pearson correlation coefficients was performed to assess the body parameters obtained by X-ray and Chuna posture analysis system. Results Significant correlations were observed between the values for Interacromial angle, Pelvic obliquity angle, SLLD, MMA and Q-angle, AHT, ASIS-PSIS angle, Interscapular angle, Scoliotic angle and Cobb's angle obtained by X-ray and Chuna posture analysis system. Significant correlations were also observed between right MMA and left Q-angle as well as between left MMA and right Q-angle. Conclusions Chuna posture analysis system can be used instead of X-ray measure body parameters and perform posture analysis in clinical practice. This study's findings are expected to serve as a basis for further research on the clinical application of Chuna posture analysis system.

Gingival fibromatosis is a rare condition characterized by varying degrees of gingival hyperplasia. Gingival fibromatosis usually occurs as an isolated disorder or can be associated with a variety of other syndromes. It usually appears at the time of eruption of permanent dentition but, can develop at the time of eruption of the primary dentition and rarely at birth. It may deform palatal contour and subsequently restrict the tongue movement, resulting in interference during speech and mastication. In addition, it incapacitates maintenance of normal lip closure. A 14-month-old girl visited the department of pediatric dentistry, Yonsei University Dental Hospital, for the congenital gingival overgrowth. There was no one in the family, who showed similar pattern of gingival growth. The intraoral clinical examination revealed generalized severe gingival enlargement throughout the maxillary and the mandibular arches. Enlarged gingival tissue was pink and had firm consistency. She was referred for chromosomal analysis, which confirmed absence of any known syndrome. Under local anesthesia, "Punch-biopsy" was performed on the labial area, and the specimen was histologically diagnosed as gingival fibromatosis. For she did not have any medical problem nor familiar history, she was diagnosed as having idiopathic gingival fibromatosis. Regarding her age and behavior, close follow-up was decided.

A bicycle is different from vehicles in the structure that a rider is fully exposed to the surrounding environment. Therefore, it needs to make use of prior information about local weather, air quality, trail road condition. Moreover, since it depends on human power for moving, it should acquire route property such as hill slope, winding, and road surface to improve its efficiency in everyday use. Recent mobile applications which are to be used during bicycle riding let us aware of the necessity of development of intelligent bicycles. This study aims to develop a riding state (up-hill, down-hill, accelerating, braking) recognition algorithm using a low-power wrist watch type embedded system which has 3-axis accelerometer and wireless communication capability. The developed algorithm was applied to 19 experimental riding data and showed more than 95% of correct recognition over 83.3% of the total dataset. The altitude and temperature sensor also in the embedded system mounted on the bicycle is being used to improve the accuracy of the algorithm. The developed riding state recognition algorithm is expected to be a platform technology for intelligent bicycle interface system.

This case study aimed to investigate changes in self-expression following participation in a rap making program with adolescent survivors of childhood cancer. The rap making program was constructed based on the contextual support music therapy model. Three adolescent survivors of childhood cancer participated in six 80-minute individual sessions. During the sessions, each participant engaged in the following tasks: song discussion, lyric creation, and rapping over a selected beat. At pre and posttest, the Self-Expression Scale was completed by participants. Their verbal expressions lyrics were observed during the sessions, and individual interviews with the participants were conducted at the completion of the program. The results demonstrated that the mean rating of the Self-Expression Scale increased after the rap making intervention. Analysis of the participants' verbal expressions and lyrics demonstrated that participants were experiencing difficulties adjusting to school that they wanted to resolve. Furthermore, the analysis of the interviews at posttest found that participants experienced positive changes in self-perception, self-expression, and expectations for their future, compared to the pretest when the participants expressed negative self-perceptions due to difficulties in interpersonal relationships at school and physical limitations. This indicates that rap making can be an effective resource for providing this population with the means to recognize positive attributes about themselves and improve self-expression.

This study aimed to identify middle school students' perceptions and practices of handwriting, and factors affecting their attitudes towards handwriting. Data were collected by means of a survey targeting 346 students enrolled in 9 middle schools(Male=172, Female=172, Unknown=2, M=13.5 years old, SD= .94). Interviews, too, were conducted with 12 students in order to identify the students' perceptions of handwriting. The analyses of both survey and interview data revealed the following: (1) the majority of the interviewee students believed that handwriting is useful for memory and summarization so as to get a better school grade, including performance evaluations; (2) Many of the interviewee students were unsatisfied with their handwriting skills, giving higher scores to their peers' handwriting; (3) 45.7% of the students reported that mother was the one who taught them how to write for the first time; and 49.7% of them had no learning experience of taking notes; (4) Girls than boys and 1st graders than 2 or 3 graders showed more positive attitude towards handwriting; and (5) A multiple regression analysis showed that all the variables entered in the regression model, including sex, grade, affective attitude toward hands-on activities, physical abilities, time spent using a computer, and perceptions of Korean characters, had significant impacts on the students' attitudes towards handwriting.

The purpose of this study was to investigate the effects of 12-week aerobic exercise training on cardiac QT intervals and cardiovascular risk profiles in type 1 diabetic children. Eleven type 1 diabetic children aged 9-17 years took part in this study as subject. The participants performed aerobic exercise training three times a week for total 12 weeks. The intensity of the training was adjusted at HRR 45% until three weeks and at HRR 55% since four weeks. After a 12-week aerobic exercise training systolic (p<0.05) and diastolic (p<0.05) blood pressure of the subjects was decreased. There was significant decrease in cardiac QT intervals (p<0.05), TC level (p<0.05), and HDL-C level (p<0.05). Therefore, the results of this study suggest that long-term regular physical activity of type 1 diabetic children considered exercise intensity and frequency may effect and play a important role in the prevention of diabetic complications and cardiovascular health care.

To evaluate the health status of the aged in rural area, 476 men and women of 65 years old and older among the residents of Gunwee County in Kyungpook were examined at the county health center between 4th and 22nd of June, 1984. Physical examination included measuring height, weight, chest circumference and blood pressure and chest x-ray. Laboratory tests were done for serum cholesterol, glucose and GOT, and urine glucose and protein. The mean heights of male and female were 160${\pm}$7.0cm and 147.7${\pm}$6.9cm, respectively. The height decreased as the age increased. The mean body weight of male was 53.5${\pm}$7.8kg and 46.7${\pm}$7.5kg for female and the older, the eighter. The mean chest circumference of male was 85.4${\pm}$7.5cm and 79.5${\pm}$79cm for female and it had no remarkable differences by age group. The average height, body weight, chest circumference, and serum cholesterol level of the age 65 years and older in rural area were lower than the standard this may be due to undernutrition of the aged. The mean diastolic and systolic blood pressure of male were 75.9${\pm}$13.5 mmHg/126.3${\pm}$24.1 mmHg and those for female were 73.1${\pm}$13.9 mmHg/125.8${\pm}$32.4 mmHg. Both male an d female in the age group of 65-69 years showed the lowest mean blood pressure. Among the study population 18.3% the borderlin hypertension and 14.3% had hypertension. Average hemoglobin level of the male(12.5${\pm}$0.8 g/dl) was higher than that of the female(11.6${\pm}$0.8 g/dl) (p < 0.01). Mean serum G.O.T. level was 25.2${\pm}$8.7 IU for male and 23.6${\pm}$7.5 IU for female and all of the study population were within the normal range. Mean serum glucose level was 110.4${\pm}$16.0 mg/dl for the male and 110.5${\pm}$15.7 mg /dl for the female and 41.4% of the study population were above the normal limit of serum glucose level. However, there was only one person she had glycosuria. Hyperglycemia could be due to non-fasting before the test. Two of the study population had proteinuria and five persons (1.05%) were diagnosed as pulmonary tuberculosis by the chest x-ray.

Bisphenol A (BPA), a chemical with weak estrogenic activity is reported to affect preimplantation embryos, fetuses and alter their postnatal development. This study amied to determine the relation between the levels of BPA in the amniotic fluid and pregnancy outcomes. ELISA was used to measure amniotic fluid BPA in 120 pregnant women who underwent genetic amniocentesis at 15~20 weeks gestation. The most common indication for amniocentesis was advanced maternal age (35 yrs or older). BPA was detected in all amniotic fluid. The range of amniotic fluid BPA concentrations was from 0.89 ng/mL to 37.13 ng/mL with a mean level of 7.24 ng/mL. We compared the means of amniotic fluid BPA concentrations according to maternal age (${\geq}35$ vs. <35 yrs), fetal sex (male vs. female), gestational age at birth (${\geq}37$ vs. <37 weeks), and infant birth weight (${\geq}2.5$ vs. <2.5 kg). No significant differences were found in these outcomes. This is the first report of amniotic fluid BPA levels in Korean pregnant women. Our findings suggest that BPA may not affect the pregnancy outcomes such as fetal sex, preterm delivery and low birth weight. Whether prenatal exposure to BPA can have teratogenic effect on developing embryo needs to be studied.

The purpose of this study was to investigate high school students' learning style, perception of types of laboratory instruction, and the relationship between the learning style and preferred type of laboratory instruction. The participants of this study were 19 female high school students, from Incheon in Korea, who showed outstanding science grades. Dunn et al's revised Learning Styles Inventory (1997) was used for testing students' learning style. The students were asked to choose preferred and not preferred types of experiments and describe the reason of the choices after implementation of 4 types of experiments: verification, discovery, explorator, and investigation laboratory instructions. The findings of this study were as follows: Firstly, the students had a certain common learning style irrelevant to their personal characteristics, i. e; they showed high (self, teacher, parents) motivation and structure stimuli that was common in Korean students. Second, outstanding students prefer unstructured and open laboratory instructions. And those students were highly influenced by sociological and emotional stimuli. Third, students' learning style was related to their preferred type of laboratory instruction. Students preferring unstructured and open laboratory were influenced by sociological and emotional stimuli, while those preferring structured and closed laboratory were influenced by physiological stimuli.
