하선영,성윤희 한국운동재활복지협회 2023 운동재활·복지 Vol.4 No.2

Children with hypotonia and hypertonia due to muscle tone problems commonly have reduced trunk stability. The study aimed to investigate the trunk and lower extremity muscle contraction pattern in a sitting position in children with muscle tone problems. For typically developing (TD) children (n = 11), children with hypertonia (n = 11), and children with hypotonia (n = 10), the muscle activity of the trunk and lower extremities and the thickness of the abdominal muscles were observed in sitting with both arms relaxed and in sitting with shoulder joint flexed 90°. Muscle activity was measured using surfaced electromyography, while muscle thickness was measured using ultrasonography. As a result, the rectus abdominal muscle activity in the sitting position was significantly lower in the TD children than in the other groups (p < .05), the hamstring activity in the sitting position with the shoulder joint flexed 90° was higher in the children with hypertonia than in the TD children (p < .05). Children with hypotonia had thinner transversus abdominis than in the other groups (p < .05). In summary, in a sitting position, children with hypotonia showed a decrease in the activity of the transversus abdominis, which is considered a local muscle, while children with hypertonia showed excessive activity of global muscles such as the external oblique and rectus abdominal muscle.

Gayageum Byeongchang is a genre of singing vocal songs like Pansori, Danga, folk song, etc. with Gayageum accompaniment by the singer in person. This study examined Teaching·Learrnig method of ‘Gogocheonbyeon,’ Gayageum Byeongchang on the basis of 2009 revised curriculum of music. As for appreciation area, in order to understand Gayageum Byeongchang in the socio-cultural context, its process of formation was investigated from the socio-cultural aspects. For understanding in the historical context, its process of transition was examined. In addition, characteristics of ‘Gogocheonbyeon’ were figured out for better understanding of its musical elements and concept. As for expression area, teaching methods for Sori and Gayageum accompaniment were suggested to express in a correct posture by going after the characteristics of musical pieces. As the basis of Sori, first, method of breathing, pronunciation, and Sigimsae were practiced and story songs were understood. As for rhythm practice, main rhythm patterns of jungjungmori were figured out. As Sea according to rhythm was expressed, playing major beat and minor beat together was practiced. As for Sori practice, songs were sung by understanding signs on melody musical notes and expressing various kinds of Sigimsae with correct pronunciation. As for teaching Gayageum accompaniment, melody of Gayageum accompaniment was reconstituted by associating with rhythm pattern of Jungjungmori. To proceed the procedure from step 1 to step 6 enable to reach the achievement criteria such as ‘to grasp the main rhythmic form of the music and play to the rhythm’, ‘to play and express the stress of the proper rhythm of music’, ‘to distinguish between various Sigimsae of the music’, to understand Jeongganbo, staff notaion and to play with expressing sign or symbol of the score. Like above, composition principle of Gayageum accompaniment melody in accordance with song melody was specifically and systematically as for Gayageum Byeongchang. When a teacher instructs singing together in Gayageum at practical educational sites, it is possible to modify 1∼6 steps depending on students’ ability and school conditions. Whether the step is high or low is not in direct proportion to essential understanding and learning of Gayageum Byeongchang. 가야금병창은 판소리, 단가, 민요 등의 성악곡을 가창자가 직접 가야금으로 반주를 하면서 노래 부르는 장르이다. 본고는 2009 개정 음악과 교육과정에 근거하여 가야금병창 ‘고고천변’의 교수․학습 방안을 제시하는 데 목적을 두었다. 표현영역에서 ‘바른 자세로 악곡의 특징을 살려 표현하기’의 내용체계에 제시된 성취기준을 달성하기 위하여 소리와 가야금반주 지도를 위한 방안을 제시하였다. 소리의 기초로서 먼저 호흡법을 익히고 통성과 시성을 구별하여 적절한 발성으로 요성, 추성, 퇴성 등의 시김새를 연습한다. 노랫말 속의 한자어의 의미를 찾아보고 그것을 문장 안에 대입시켜 해석하고, 단어와 어미의 사투리적 표현, 서자침 등의 발음에 유의한다. 장단 익히기에서는 중중모리 장단의 주박과 부박을 활용하여 다양한 패턴을 연습하였고, 소리 익히기에서는 가락선 악보에 나타난 부호들을 이해하여 정확한 발음으로 여러 가지 시김새를 표현하여 노래 부르도록 하였다. 가야금반주 지도에서는 중중모리 장단의 리듬꼴과 연계하여 단계별로 가야금 반주선율을 재구성하였다. 1단계부터 6단계까지의 과정을 순차적으로 진행하여 ‘악곡의 주요 장단꼴을 파악하여 장단에 맞추어 연주하기’, ‘악곡에 알맞은 장단의 세를 표현하며 연주하기’, ‘악곡의 여러 가지 시김새를 구별하여 표현하기’, ‘정간보나 오선보를 이해하고 악보의 부호나 기호 등을 표현하여 연주하기’ 등의 성취기준에 도달할 수 있다. 이상과 같이 가야금병창에서 노래선율에 따른 가야금 반주선율의 구성 원리를 구체적이고 체계적으로 제시하였다. 실제 교육 현장에서 교사가 가야금병창을 지도할 때에는 1∼6단계 중 학생의 능력과 학교 여건에 따라 조정이 가능하며, 단계의 높고 낮음이 가야금병창의 본질적 이해와 학습과 비례하지는 않는다.

하선영,성윤희 한국신경근육재활학회 2022 한국신경근육재활학회지 Vol.12 No.1

The trunk muscles include the abdominal and scapular muscles, and strengthening them improves trunk stability. We investigated the effect of scapular strengthening exercise with and without band on trunk muscles and abdominal muscles activities. In 34 healthy men, scapular strengthening exercises A (scapular adduction) and B (scapular adduction with shoulder external rotation) with and without bands were applied. Electromyography was used to measure the muscle activity of latissimus dorsi (LD), lower trapezius, and erector spinae, and ultrasonography were used to measure the thickness of the abdominal muscles. Muscle activity was measured during the motion and during maintaining it, and muscle thickness was measured during maintaining the motion. As a result, LD activity was the highest in scapular strengthening exercise A with band, and there was no significant difference in abdominal muscle thickness with or without band. Therefore, scapular strengthening exercise A with band is considered to be the most effective method to improve LD activity.

Abdominal and lower extremity muscles activity and thickness in typically developing children and children with developmental delay

하선영,성윤희 한국운동재활학회 2022 JER Vol.18 No.6

We investigated abdominal and lower extremity muscle activity and thickness in typically developing children and children with developmental delays. A total of 35 children participated: typically developing peers (n= 13), children with hypotonia (n= 10), and children with spasticity (n= 12). Muscle activity and thickness were measured at rest and during activity. Electromyography was used to measure abdominal and lower extremity muscle activities, and abdominal muscle thickness was measured using ultrasonography. There was a significant difference between the groups in the activity of the rectus abdominis and quadriceps muscles at rest and during activity (P< 0.05). There was a significant difference between the groups in the thickness of the external oblique and transversus abdominis muscles during activity (P< 0.05). There was a significant difference between the groups in the thickness of the external oblique and internal oblique muscles in the sitting position (P< 0.05). Therefore, the characteristics of muscle tone should be considered when applying interventions to children with developmental delay.

The relationship between near misses and major accidents can be confirmed using the ratios proposed by Heinrich and Bird. Systematic reviews of previous national and international studies did not reveal the assessment process used in near-miss management systems. In this study, a model was developed for assessing near misses and major factors were derived through case application. By reviewing national and international literature, 14 factors were selected for each dimension of the P2T (people, procedure, technology) model. To identify the causal relationship between accidents and these factors, a near-miss assessment model was developed using a Bayesian network. In addition, a sensitivity analysis was conducted to derive the major factors. To verify the validity of the model, near-miss data obtained from the ethylene production process were applied. As a result, “PE2 (education),” “PR1 (procedure),” and “TE1 (equipment and facility not installed)” were derived as the major factors causing near misses in this process. If actual workplace data are applied to the near-miss assessment model developed in this study, results that are unique to the workplace can be confirmed. In addition, scientific safety management is possible only when priority is given through sensitivity analysis.
