긴장성 두통은 성인들에게 나타나는 두통 중 가장 흔한 일차성 두통이다. 장기간의 두통은 만성 두통을 야기시키고 일상생활에 큰 영향을 미친다. 본 연구의 목적은 긴장성 두통의 병원성 요인과 심인성 요인의 관리에 적합한 시청각적 엔터테인먼트와 연부조직 가동술을 통해 긴장성 두통에 기여하는 바를 비교하고자 한다. 연구대상은 6개월 이상 간헐적 혹은 지속적인 두통을 호소한 자로 선정된 30명에서 시청각적 엔터테인먼트군, 연부조직 가동술군, 시청각적 엔터테인먼트와 연부조직 가동술군 각각 10명씩 배정하였다. 배정된 군에서는 사전검사 후 4주간 주 3회씩 총 12회의 중재를 받고 사후검사를 실시하였다. 평가는 압력통각역치감각과 바이오피드백을 이용한 정신 생리학적 변수, 뇌파를 측정하였다. 측정된 결과는 이요인 반복측정 분산분석을 통해 측정 시점에 따른 군간의 교호작용을 분석하였다. 압력통각역치 결과, 오른쪽 등세모근의 결과에서 교호작용이 나타났으며 (p<.05), 시청각적 엔터테인먼트를 통한 중재군에서 가장 큰 증가의 폭을 보였다. 따라서 병원성 요인의 근육에 대한 직접적인 접근이 아닌 심리학적인 요소에 입각한 시청각적 엔터테인먼트를 통해 근육에 대한 통증역치에 긍정적인 영향이 보였지만 통계학적으로 유의하지 않았던 정신생리학적 변수와 뇌파에도 긍정적인 평균값의 변화량이 관찰되었다. 이를 통해 긴장성 두통의 관리에 있어 시청각적인 자극은 고려되어야 한다고 제언한다.

Although Korean university students' primary concern is academic success in their higher degrees in the UK, they highly desire to develop English communicative competence through a number of opportunities to speak with natives speakers. The paper aims at examining to what extent they are able to be socialised into a new environment while they are studying at UK universities. The in-depth, longitudinal interviews with the targeted group of six Korean masters' students at the University of York was undertaken to observe the pace of their progress in developing social skills. Reluctance and hesitance to contact and interact with their supervisors and other academic staff persisted for most of them to the final term caused by cultural reasons such as face and hierarchy rather than language problems. Despite the six participants' variation in their patterns of social interaction, they struggled with pressures towards monoculture-biased interaction with Korean people, which was quite extreme for the five participants. This passivity can be explained by several reasons such as the students' lack of communicative competence and other situational factors on one-year course. It is important to note that students' failure to develop network with native speakers is strongly associated with experience of cultural withdrawal and frustration with developing communicative competence in English.

Purpose : To provide data on exercise prescription for obesity management and prevention of cardiovascular disease in girl's high school and to prepare basic data for more effective exercise program for lifestyle improvement and prevention of lifestyle-related diseases. This study examines the effects on brain nerve growth factor and inflammatory factors, and the relationship between obesity factor and brain neuron cell production factor and inflammatory factor changes by complex exercise. Methods : The subjects of the study were obese students with a body fat percentage of 30 % or higher after obtaining body fat percentage of high school girls in C-city. Among them, 20 students who wanted to participate in the program of this study and did not participate in special exercise and diet therapy within the last 6 months were radio-sampled into groups of exercise group and control group, but attendance rate was low and The final exercise group (9) and control group (9) were measured, except for one student who did not respond. Results : Analysis of the range of variation in body composition, BMI, lean body mass, and the interaction between the groups showed significant differences (p<.05). TC, TG, HDL-C, and LDL-C as variables of blood lipids, TC and TG were not significantly different and TG was significantly different (p<.05) in interactions. HDL-C showed a significant difference (p<.01) in interactions, an increase in exercise group, and a significant decrease in control group (p<.05). There was a significant difference (p<.05) in BDNF interaction, an increase in the exercise group and a decrease in the control group, but no significant difference. NGF tended to increase in both exercise and control groups. IL-6 had a significant difference in timing (p<.05) and significantly decreased (p<.01) in the exercise group, and TNF-α interacted with timing (p<.05), and a significant increase in the control group. Conclusion : This study confirmed 12-week compound exercise program was effective in increasing the expression of basal fitness or CNS factor, but not enough to actually improve brain function. Fat mass and obesity are also affecting vascular inflammatory factors.

Purposes: Study purpose were to describe growth patterns of premature infants in weight, length and head circumference from birth to 40th week of corrected ages (CA) and to explore factors affecting patterns. Methods: A longitudinal descriptive study was conducted with 267 premature infants. They were categorized into 2 groups; GA group with measurements at birth and the CA group with measurements at CA, which was categorized into 3 groups (group 1-3) by WHO guideline for gestational age (GA) at birth. Results: GA group presented greater measures in all than CA group at same week of life. Among CA groups, group 3 showed the highest measurements, up to 37 weeks of life, though this disappeared at 38-40 weeks. Reversely, group 1 revealed the highest growth rates in all measures, followed by group 2 and group 3. Significant interaction was observed in all measures between week of life and any type of groups. Conclusions: Higher measures in GA group, as well group 3 among CA groups, supported the superiority of intra-uterine environment overriding quality of regimen from NICU. Regardless of growth acceleration, smaller infants remain smaller, indicating that intra-uterine thrifty phenotype may continue at least up to the 40th week of CA.

Statement of problem: For the long-term success of removable partial dentures, the bonding between metal framework and denture base resin is one of the important factors. To improve bonding between those, macro-mechanical retentive form that is included metal framework design has been generally used. However it has been known that sealing at the interface between metal framework and denture base resin is very weak, because this method uses mechanical bonding. Purpose: Many studies has been made to find a simple method which induces chemical bond, now various bonding system is applied to clinic. In this experiment, shear bond strengths of heat-cured denture base resin to the surface-treated Co-Cr alloy were measured before and after thermocycling. Chemically treated groups with Alloy $Primer^{TM}$, Super-Bond $C&B^{TM}$, and tribochemically treated group with $Rocatec^{TM}$ system were compared to the beadtreated control group. The data were analyzed with two-way ANOVA. Result: 1. Shear bond strength of bead-treated group is highest, and Alloy $Primer^{TM}$ treated group, Super-Bond $C&B^{TM}$ treated group, RocatecTM system treated group were followed. Statistically significant differences were found in each treated group(p<0.05). 2. Surface treatment and thermocycling affected shear bond strength(p<0.05), however there was no interaction between two factors(p>0.05). 3. Shear bond strengths of bead-treated group and Alloy $Primer^{TM}$ treated group showed no statistically significant difference before and after thermocycling(p>0.05), and those of Super-Bond $C&B^{TM}$ treated group and $Rocatec^{TM}$ system treated group showed statistically significant difference after thermocycling(p<0.05).

Objects: The prevalence of asthma has increased in recent decades globally. The objective of the present study is to elucidate whether hospitalization for bronchiolitis in infancy and low socioeconomic status interact for bronchial hyperreactivity during teenage years. Method: We studied 522 children age 13-14 years attending schools in rural and urban areas to investigate the risk factors for bronchial hyperreactivity (BHR), defined as a provocation concentration of methacholine that causes a decrease of 20% ($PC_{20}$) in forced expiratory volume within 1 second. Clinical examination, skin prick test, spirometry, and methacholine challenge were performed on all study subjects, who provided written consent. We used multivariate logistic regression to investigate the risk factors for BHR, and analyze the interaction between hospitalization for bronchiolitis in infancy and low socioeconomic status. Results: Forty-six (10.3%) positive BHR cases were identified. In the multivariate logistic analysis, as independent predictors of BHR, adjusted odds ratio of bronchiolitis diagnosed before 2 years of age in low income families was 13.7 (95% confidence interval, 1.4 to 135.0), compared to reference group, controlling for age, gender, parental allergy history, skin prick test, and environmental tobacco smoke (ETS) exposure. Interaction was observed between bronchiolitis before 2 years old and low socioeconomic status on children's bronchial hyperreactivity (p-interaction=0.025). Conclusions: This study showed that bronchiolitis diagnosed before 2 years of age and low socioeconomic status interacted on children's bronchial hyperreactivity. Prevention of acute respiratory infection in early childhood in low socioeconomic status is important to prevent BHR as a precursor of asthma.

제7기 국민건강영양조사 자료(2016~2018)를 이용해서 고감도 C반응성 단백(hsCRP)과 요산의 비만에 대한 위험도와 상호 작용이 있는지 알아보고자 하였다. 비만은 체질량지수(BMI)가 25 kg/m² 이상으로, 중증 비만은 BMI가 30 kg/m² 이상으로, 병적 비만은 BMI가 35 kg/m² 이상으로 정의하였다. 복합표본 다중 로지스틱 회귀분석에서 주요한 위험인자를 추가하여 보정하였음에도 불구하고 고농도의 hsCRP와 고농도의 요산이 동시에 존재하는 그룹은 기준 그룹보다 비만의 오즈비(odds ratio, OR)가 모든 단계에서 높았다(비만, OR 1.89, P<0.001 vs. 심한 비만, OR 5.04, P<0.001 vs. 병적인 비만, OR 8.20, P<0.001). 비만의 단계가 높아질수록 비만에 대한 hsCRP와 요산의 오즈비가 1.89에서 8.20으로 높아졌다, 이는 BMI가 증가된 참가자일수록 hsCRP와 요산의 관련성이 크다는 것을 암시한다. 더욱이, 복합표본 일반선형분석에서 주요한 교란 요인을 보정한 후 비만에 대한 hsCRP와 요산 사이의 상호 작용이 분석되었다(P for interaction=0.009).
