  • The purpose of this study was to investigate the relationship between the head and neck postre and the cervical curvature, especially in forward head postrue(FHP). Sixty patients with craniomandibular disorders and thirty dental students without any signs and symptoms of craniomandibular disordres participated in this study as patient groups and sa control group, respectively. The author evaluated the head and neck posture of all subjects by plumb line and CROM( Cervical Ragne of Motion), and had taken cephaograph in natural head position. On the cephalograph the angle of cervical inclination formed by true horizntal plane and 4th cervical vertebra(C4) and the radius of cervical curvature from C1 to C5 were measured. A specially designed ruler was used for measuring cervical curvature. Occlusal contac number and force with T-scan system, electromygraphic activity of cervical muscles with Bio-EMG, and distance of freeway space with Bio-ECN were recorded, respectively. The collected data were processed by SAS/STAT progrm. The obtained results were as follows : 1. In subjects with longer radius which was less cervical curvature, head positioned more anteriorly than subjects with smaller radius, and they showed slightly straight cervical vertebra. 2. Between the patients and the control group, there were no differences in cervical curvature, in forward head position by plumb line and in CROM. But the patient group had a greater cervical inclination than the control group had. 3. There were positive correlation between cervical curvature and forward head position by plumbline,between forward head position y plumb line and that by CROM in patient group. The cervical inclination, however, had negative correlation with cervical curvature, and with forward head postion by plumb line, respectively. 4. In case of showing more cervical curvature and more forward head position by plumb line the head position was defined as forward head posture. In patient group, subjects without forward head posture showed greater posterior teeth contact force than subjects with forward head posture, but in control group, there were no difference between the two subjects. 5. There were higher electromyographic activity in almost all muscles and smaller freeway space in induced forward head posture than those in natural head position in subjects without forward head posture. In conclusion, head position of patients with craniomandibular disorders were not more anterior than that of normal control person, but they had tendency to head extension. From the result of this study, forward head posture could be defined as posterior rotation of upper cervical segment with a straight lower cercial segment due to loss of normal lordosis.

  • Objectives: The purpose of this study is to investigate the effect of exercise load on sleep structure and stress hormone secretion during sleep. Methods: Five male physical education students were included in this study after giving their written, informed consents in the Research Institute for Sports Science at the University of Hanyang. All subjects have performed for at least 3 years in a regular aerobic exercises such as football, basketball, and running. The subjects were divided into three groups ; NOE(non-exercise), MDE(middle duration exercise), LDE(long duration excercise). MDE group maintained a total of 120 min exercise, and LDE group maintained a total of 300 min exercise by football, basketball or badminton. All subjects were acclimatized to the experimental sleep condition by spending one night under expermental conditions, including the placement of an intravenous catheter. During the subsequent night(24:00-08:00), somnopolygraphic sleep recordings were obtained, and blood for measuring growth hormone, cortisol, testosterone, and $\beta$-endorphin was collected every 120 min throughout the night. Blood samples were obtained from prominent forearm veins of subjects. Then, the samples were immediately placed in ice and centrifuged within 10 min at 3000 rpm at $4^{\circ}C$. Statistical analyses were performed using the SPSS/$PC^+$. Data were analyzed by one-way ANOVA with repeated measures. Results: No significant differences among groups were observed in sleep latency, total sleep time, stage 2 sleep, and slow wave sleep. However, daytime exercise produced significant changes in stage 1 sleep, REM sleep, stage 2 sleep latency, REM sleep latency and sleep efficiency. Stage 1 sleep, stage 2 sleep latency, and REM sleep latency significantly increased in LDE compared to those of NOE and MDE groups. But the amount of REM sleep significantly decreased in LDE. Sleep efficiency of MDE was higher than those of NOE and LDE. The blood concentrations of growth hormone, testosterone, and cortisol during night sleep were significantly lower in LDE than in NOE. $\beta$-endorphin concentrations in blood during night sleep were not different among groups. Conclusion: The daytime exercise load was significantly related to sleep structure and stress hormone secretion during night sleep. Long duration exercise showed a harmful effect on sleep structure and hormone secretion. However, middle duration exercise had a beneficial effect on sleep structure and hormone secretion during sleep.

  • This study aimed to investigate whether mass drug administration (MDA) intervention has an equivalent effect on reducing the prevalence and intensity of Schistosoma haematobium infection regardless of the baseline values. A repeated cross-sectional survey was performed targeting students of 12 primary schools in Al Jabalain and El Salam districts of White Nile State, Sudan, at both 1 week before and 8 months after the MDA. Prior to the baseline survey, schoolaged children in Al Jabalain had received MDA interventions twice in 4 years, while those in El Salam had not. The baseline prevalence was 9.1% in Al Jabalain and 35.2% in El Salam, which were reduced to 1.8% and 5.5% at 8 months after the MDA, respectively. The corresponding reduction rates were 80.3% and 84.4%, not significant difference between both districts. However, changes in the geometric mean intensity (GMI) of egg counts were significantly different between both districts. The baseline GMIs were 14.5 eggs per 10 ml of urine (EP10) in Al Jabalain and 18.5 EP10 in El Salam, which were reduced to 7.1 and 11.2 EP10 after treatment, respectively. The corresponding reduction rates were 51.0% and 39.5%. In conclusion, MDA interventions were found to bring about similar relative reduction in prevalence regardless of the baseline value; however, the relative reduction in infection intensity was more salient in the district with a low baseline value for both prevalence and intensity. This clearly points to the importance of repeated MDA interventions in endemic areas, which will eventually contribute to schistosomiasis elimination.

  • 본 연구는 제주시 지역 일부 초등학교 4 5학년 비만아동 117명 (남자 70명, 여자 47명)과 정상체중아동 117명 (남자 70명, 여자 47명)을 대상으로 일반사항, 체중감량 관련 식행동, 간식 식습관을 조사하였으며, 더불어 24시간 회상법을 이용하여 식이섭취실태를 파악함으로써 초등학교 고학년 학생들의 간식섭취 및 균형 잡힌 영양소섭취를 위한 교육자료 개발을 위한 기초자료를 제공하고자 하였으며, 연구결과는 다음과 같다. 조사대상자의 평균 신장, 체중 및 비만도는 각각 정상체중아동은 143.8 cm, 38.5 kg, -0.42%이며 비만아동은 147.5 cm, 56.6 kg, 35.4%로 모두 체중군에 따라 유의한 차이가 있었으나, 체중군별 열량 섭취량은 유의적인 차이를 보이지 않았다. 하지만 조사대상자의 체중감량 관련 식행동에서 식사량 감소 경험 유무와 살찌는 음식임을 고려하여 섭취하는 비율은 체중군별 유의적인 차이를 보였다. 조사대상자의 총 열량 섭취 열량은 아침, 점심, 저녁, 간식이 각각 289.8 kcal, 569.0 kcal, 499.2 kcal, 325.1 kcal로, 끼니별 열량 섭취 비율은 17.2%, 33.8%, 29.7%, 19.3%로 나타났다. 특히 간식으로 섭취하는 열량은 체중군별 유의적 차이는 없었으나, 특정 간식 음식을 섭취한 아동만을 대상으로 분석하였을 때, 비만군이 정상체중군에 비해 사탕 초콜릿류를 유의적으로 더 많이 섭취하고 있었다. 성별과 체중군별로 간식을 섭취하는 이유로는 공통적으로 '배가 고파서'가 64.1%, '심심해서'는 12% 순으로 나타났다. 간식 섭취 횟수에서 일반 간식의 경우 정상체중군 (2.1회/주)이 비만군 (1.6회/주)보다 자주 섭취하는 것으로 나타났고, 학교나 학원 주변에서 섭취하는 간식의 경우에는 체중군별 차이 (1회/주)가 없었다. 일반 간식과 학교나 학원 주변 간식을 합한 총간식의 섭취 횟수는 정상체중군은 3.1회/주, 비만군은 2.6회/주로 나타났다. 일반 간식에서 자주 먹는 간식 음식은 과일 과일주스, 과자 사탕 초콜릿, 우유 요구르트 순으로 높게 나타났고, 학교나 학원 주변 간식에서는 김밥 삼각김밥 떡볶이 순대, 아이스크림, 과자 사탕 초콜릿의 순으로 높게 나타났으며, 체중군별 간식 선택 음식의 종류에는 유의적 차이가 없었다. 하지만 간식음식을 저열량 고영양 간식과 고열량 저영양 간식으로 구분하고, 간식 음식선택 여부와 섭취 횟수를 고려한 섭취 수준으로 비교하였을 때에는 비만군이 정상체중군보다 저열량 고영양 간식의 섭취수준이 유의적으로 낮게 나타났다. 이상의 결과를 종합해 볼 때 본 제주의 일부 초등학교 5, 6학년 학생들은 체중군별로 비만군이 정상체중군에 비해 체중 감량을 위해 더 노력하지만, 비만군이 정상체중군보다 저열량 고영양 간식을 유의적으로 낮게 섭취하는 것을 알 수 있었다. 고열량 저영양의 부적절한 종류의 간식음식의 섭취는 하루 세끼 식사에 영향을 미치고, 영양 불균형을 초래할 수 있으므로 비만군 뿐만 아니라 정상체중군에서도 올바른 간식 선택 및 식행동 개선을 위한 영양교육이 필요하다고 사료된다. 균형 잡힌 하루 세끼 식사를 충분히 섭취한 후, 부족한 부분을 간식으로 보충할 수 있도록 영양적인 측면과 관련지어 간식 섭취에 대한 적절한 교육이 학교에서 뿐만 아니라 가정연계를 통해 체계적으로 전개되어야 하겠다.

  • Purpose: This study was conducted to identify the sexual maturation, parenting attitude, maturity fear and emotional and behavioral problems of girls in elementary school, and to examine the relation between these variables and factors that influence emotional and behavioral problems. Methods: Participants were 128 second, third and fourth year students from 3 elementary schools. Data were analyzed using t-test, ANOVA and $Scheff{\acute{e}}$ test, Pearson correlation coefficients, and stepwise multiple regression with SPSS/WIN 21.0. Results: Emotional and behavioral problems were related to eating rate, eating breakfast, frequency of late-night snacks and main communicator on pubertal development. Emotional and behavioral problems showed a positive correlation with maturity fear and father's parenting attitude (strictness) and a negative correlation with parenting attitude and father's parenting attitude (intimacy). Maturity fear, father's parenting attitude, eating breakfast, and main communicator on pubertal development had significant influence on emotional and behavioral problems of girls in elementary school. Conclusion: Findings show that for effective management of emotional and behavioral problems in elementary school girls, programs including coping with maturity fear, supportive parenting of father, diet education, and functional communication with mother on pubertal development should be developed.
