국내 와인 상품의 활성화를 위한 소재 개발 연구

두영택,임도연 한국상품학회 2022 商品學硏究 Vol.40 No.3

건강식품 문화 확산으로 현대 사회인들은 고품질의 와인을 선호하고 있고 또한 알코올 함량이 비교적 낮은 양조주를 선호하고 있다. 와인의 긍정적인 측면이 언론 매체에 알려지면서 와인 수요는 점점 증가하고 있다. 그러나 한국 국세청 보도 자료에 따르면 와인의 소비 및 점유율은 대부분 수입산 와인이 차지하고 있고 국내산 와인 시장 점유율은 매년 하락하는 추세이다. 증가하고 있는 와인 수요를 국내산 와인으로 활성화 시키기 위하여 와인 제조 방법 및 소재 개발이 절실하기에 항산화 효과가 높은 커피 나무 열매인 커피 은피를 활용하여 와인을 제조하였다. 커피 은피 추출물에 설탕을 중량대비 1 : 0.8~1.2의 비율로 혼합하여 발효액을 제조하여 25~28℃에서 80~120일 동안 발효하여 발효액을 제조하였다. 발효액을 제조한 후 발효액 100중량부에 치아황산나트륨 0.03~0.1중량부, 구연산0.5~1.5중량부, 물 500~800중량부를 혼합한 후, 상기 혼합물에 설탕을 15~20 brix가 되도록 첨가하여 20~28℃에서 15~20일 동안 숙성을 시킨다 숙성을 시킨 후 숙성액 100중량부에 효모분말 0.2~0.5중량부를 접종하고, 15~18℃에서 30~50일 동안 저온발효단계를 진행하여 커피은피 와인을 완성한다. 항산화 효과가 높은 커피 나무 열매인 커피 은피를 활용하여 제조된 커피 은피 와인은 와인 시장에서 와인 제조의 다양화와 건강 기능성 식품의 확장을 가져올 수 있으며 국내 와인 점유율을 높이는데 기여할수 있다. 또한 커피 은피 추출물을 활용한 와인은 커피 부산물인 커피 은피를 활용함과 동시에, 항산화 및 항균 효능이 있는 와인을 제공하여 국내 와인 시장의 활성화와 건강 기능성 식품 연구에 기초자료를 제공하는데 의의가 있다.

[PURPOSE] To examine relationships between cervical range of motion, scoliosis angle, posture, static balance and plantar pressure in patients with chronic neck and back pain, and with postural deviations. [METHODS] Sixty nine male and female adult subjects with chronic neck and back pain participated. Cervical ranges of motion were measured using CROM. Scoliosis angles were measured using scoliometer. Leg lengths were measured using a tape measure. Plantar pressure was measured using foot scan, and static equilibrium was measured using TETRAX. [RESULTS] There was a statistically positive correlation between NDI and MDQ (p<.05), and a negative correlation was found between NDI, MDQ and cervical range of motion(p<.05), while there were statistically positive correlations between scoliosis angle, plantar pressure and stability index (p<.05). [CONCLUSIONS] The increased MDQ resulted in an increase in NDI. Also, as the increased NDI and MDQ resulted in a decrease in cervical range of motion and equilibrium. However, the increased NDI and MDQ resulted in an increase in scoliosis angle, plantar pressure on forefoot and hindfoot. It is concluded that these results suggest that one must maintain correct posture and perform strength exercise together with proper gait in order to resolve difficulties in activities of daily living due to chronic neck and back pain. Also, It is suggested that older patients with chronic neck and back pain would improve static equilibrium.

PURPOSE] The purpose of this study was to investigate the correlation between leg length difference with pelvic and shoulder level, weight distribution, ankle muscle strength. [METHODS] The subjects were consisted of 49 female students whose leg length was 15mm or more among 90 female. The height of the pelvis and shoulder level were measured using the Global Posture System (GPS). The foot pressure was measured using a foot scan, and ankle muscle strength was measured using a Commander Muscle Tester. [RESULTS] There was a statistically significant positive correlation between structural leg length, pelvic height, shoulder height, and ankle instability(p<.05), while ankle dorsiflexion and inversion muscle strength were statistically significant negative correlation(p <.05). [CONCLUSION] The greater the difference in leg length, the greater the difference in pelvic level. The greater the difference in shoulder level, the greater the dorsiflexion strength of the ankle joint, especially the higher the shoulder height, the greater the ankle dorsiflexion strength. It was found that the greater the dorsiflexion strength of the ankle joint, the less the inversion strength. In conclusion, misalignment of the lower limb may cause back and neck and shoulder pain and ankle joint injury, so it is necessary to recognize the importance of proper posture and habit of the lower limbs.

두영택 ( Young Taek Doo ),엄우섭 ( Woo Seob Eom ) 서울敎育大學校 初等敎育硏究所 2016 한국초등교육 Vol.27 No.2

본 연구의 목적은 주니어 야구 투수 선수를 대상으로 정적 움직임(등척성 수축)과 동적 움직임(직구, 커브) 시 위팔두갈래근(biceps brachii)과 위팔세갈래근(triceps brachii)의 근 불 균형을 알아보고자 근활성도를 비교하는 것이다. 초·중·고학생 야구 투수 선수 40명을 대상으로 총 5초 동안의 정적 움직임(등척성 수축)과 동적 움직임(직구, 커브) 근전도를 3번 반복 측정하여 최대 수의적 등척성 수축(%MVIC)을 분석하였다. 근전도 전극은 위팔두갈래근은 봉우리뼈(acromion)와 팔꿈치 사이의 1/2 지점에, 위팔세갈래근은 봉우리뼈와 팔꿈치 머리 (olecranon) 사이의 1/2 지점에 각각 부착하였다. 유의 수준은 = .05로 설정하였다. 정적 움 직임 시 위팔두갈래근과 위팔세갈래근의 최대 수의적 등척성 수축은 유의한 차이가 있었다 (p<0.05). 동적 움직임 중 직구와 커브 모두 위팔두갈래근과 위팔세갈래근의 최대 수의적 등 척성 수축은 유의한 차이가 있었다(p<0.05). 정적움직임과 동적 움직임 시 위팔두갈래근과 위 팔세갈래근의 어깨 근육의 근력 불균형은 주니어 야구 투수의 볼 속도, 커맨드능력, 그리고 경기력 등의 저하와 같은 결과를 초래할 수 있기 때문에 본 연구의 결과가 어깨 근육의 근력 불균형이 발생된 주니어 야구 투수의 재활이나 트레이닝의 기초자료로 활용될 수 있을 것으로 생각된다. The purpose of this study was to compare electromyographic activity to muscle unbalance of biceps brachii and triceps brachii during the static movement (isometric contraction) and dynamic movement (straight ball, curve ball) in junior baseball players. The subjects were consisted of forty baseball pitcher in elementary, middle, and high school. After repeated were repeatedly three times measured by electromyographic activity of the static movement (isometric contraction) and dynamic movement (straight ball, curve ball) during the 5 sec, analyzed %MVIC. We attached EMG electrode to acromion and moiety between elbow of biceps brachii, moiety between acromion and olecranon of triceps brachii. Significance level was 0.5. %MVIC.of biceps brachii and triceps brachii during the static movement (isometric contraction) was significantly difference (p<0.05). All %MVIC of biceps brachii and triceps brachii during dynamic movement (straight ball, curve ball was significantly difference (p<0.05). Because shoulder muscle strength unbalance of biceps brachii and triceps brachii during the static movement(isometric contraction) and dynamic movement(straight ball, curve ball) bring to ball velocity, command ability, and performance decline, Therefore, this study will help rehabilitation training and training in junior baseball players who had shoulder muscle strength unbalance by base line data.
