천마(Gastrodia Rhizoma)는 뽕나무 버섯과 편리공생하는 난초과(Orcbidan ceae)에 속하는 다년생 초본인 천마(수자해좇, 정풍초, Gastrodia elata Blume)의 뿌리를 지칭하는 것으로서 잎이 없으며, 땅속의 괴경이 한약재로 이용된다. 주로 고혈압, 신경성질환, 당뇨병 등의 성인병 뿐 아니라 스트레스해소, 피로회복 등에 효과가 있는 것으로 알려져 있는 한약재이다. 천마의 주요 효능으로는 항경련 작용 및 항간질 작용에 대한 보고가 있으며, 약리작용을 나타내는 주요성분은 gastrodin, p-hydroxy benzyl alcohol, p-hydroxy benzyl aldehyde, vanillin등의 ployphenol성분으로 알려지고 있다. 한편 두부는 동물성 단백질 식품과는 다르게 열량과 포화지방 함량이 낮고 콜레스테롤이 함유되어 있지 않으며 ,가격이 저렴하여 경제적인 단백질 식품으로 각광받고 있다. 따라서 임상적, 약리적 효능이 있는 물질을 강화하여 기존두부에 비해 영양학적인 기능성을 향상시킬 목적으로 두유에 천마즙을 혼합하여 제조하였고, 기능성 두부제조시 가수량, 가열시간 및 천마즙의 첨가량이 두부수율에 미치는 영향과 텍스쳐, 색도, 탁도, 세균수 등의 품질특성을 일반 두부와 비교·검토하였다.

선원은 충분한 수면으로 신체적 정신적 피로를 완전히 회복하지 못한 수면부족 상태에서 재승선하여 장기간 항해와 흔들리는 선박 위에서 반복적인 작업 활동을 수행하므로 누적 피로도와 스트레스가 증가하는 악순환을 초래하며 이로 인한 해양 인적사고가 발생할 수 있다. 따라서 사람의 주관적인 판단에 의한 자기평가방법으로 기입하는 설문지 분석이 아닌 선박에 승선하는 동안에 Wearable device를 착용한 상태에서 과학적이고 객관적인 선원의 수면 시간과 효율성을 분석하였다.

This study was conducted to understand the meaning and nature of the compassion fatigue experiences among nurses working in oncology wards. The participants in this study were 11 nurses who worked for at least 6 months in oncology wards. The data were collected using in-depth interviews and analyzed using the phenomenological method by Giorgi. Six categories of the meaning of compassion fatigue were derived as follows; physically difficulty, emotion is control of patient's condition, collapsing in front of cancer patients, reminding of patient-related memory, finding a changed attitude, and searching for how to recover.

본 연구에서는 균열 치유 거동을 가지는 소결된 Mullite/SiC의 모재, 열처리재, 균열재, 치유 균열재의 기계적 특성이 논의되었다. 반타원형 균열의 치수는 $100{\mu}m$ 과 $200{\mu}m$이다. 얻어진 결과는 다음과 같다. (a) Mullite/SiC 복합 세라믹스는 균열 치유 능력이 있었다. (b) 최적의 균열 치유 열처리 조건은 $1300^{\circ}C$, 1시간이었다. (c) 치유 가능한 최대 균열 길이는 직경 $100{\mu}m$의 반타원 균열이다. (d) 균열 치유부는 $1200^{\circ}C$이상에서 충분한 강도를 가졌고, 대부분의 시험편은 균열 치유부 이외의 영역에서 파단 하였다. (e) 공기중에서 예열처리는 본 재료의 피로강도 향상에 유용하였다.

불포화지방산이 풍부한 오리고기는 예로부터 보양식으로 많은 사랑을 받았다. 오리고기가 기력을 회복하는 음식으로 널리 알려진 이유는 필수 아미노산과 레시틴이라는 성분이 풍부하기 때문이다. 아미노산은 근력 향상에 도움을 주고 신체 능력을 강화하며 피로 해소에도 탁월한 역할을 한다고 알려지며, 레시틴이 부족할 경우 피로를 느끼고 면역력이 저하되기 때문에 꾸준하게 섭취를 해주는 것이 중요하다. 오리에 풍부한 비타민A는 체내 병균 저항력을 높여준다. 또한 면역 세포의 기능을 촉진해 감염 질환이 걸리지 않게 몸을 보호하는 역할을 한다. 특히 비타민A가 부족하면 호흡기계 질환이 걸리기 쉬우므로 호흡기 건강에 신경을 쓴다면 평소 비타민A가 풍부한 음식을 먹는 게 좋다. 또한 오리고기에 풍부한 리놀레산은 성장기에 꼭 필요한 필수 지방산으로 인체 기능에 꼭 필요한 요소다. 다른 육류에 비해 열량이 낮고 단백질이 풍부해 다이어트를 할 때도 부담없이 즐길 수 있는 오리고기 신제품을 소개한다.

The main purpose of this paper is to evaluate the possibility of improvement in fatigue resistance of asphalt concrete mixture using the industrial waste material of K fiber. In this research, as an experimental equipment, the MTS with Closed-Loop Servohydraulic System was used and it was designed according to the U.S. standard testing procedure of ASTM D 4123. According to the test results, the optimum content of fiber with the length of 8mm was about 0.2 percent of total mixture weight. The optimum asphalt content for the fiber-reinforced asphalt concrete was about 5.5 percent of total mixture weight. Fatigue resistance of fiber-reinforced asphalt concrete was noticeable compared to the conventional dense-graded 20 asphalt concrete. In addition, the resilient moduli of fiber-reinforced asphalt mixture were $1.15{\sim}1.18$ times higher than those of conventional asphalt concrete.

This study will be targeting 21-24 years old college students majoring in physical education. This study covers the effect of kinesiology taping and icing treatment on the recovery rate of blood lactate concentration, and cardiovascular function so that it can provide the basic data for improving physical performance. As a result of this study, Kinesio taping and icing aid the recovery rate of the maximum load of lactic acid recovery rate and 30 minutes after exercise heart rate after exercise, but increased, after 15 minutes, immediately after exercise heart rate, exercise lactate and heart rate, and 30 minutes after exercise lactate showed no difference. In conclusion, Kinesio taping and icing treatment, reduce pain and fatigue but it is not satisfactory. Further study, applying a more accurate and technical form of exercise programs needs to continuously research the effects of Kinesio taping and icing treatment

The purpose of this study was to examine the effect of D-ribose supplementation on the changes of blood fatigue substances (lactate, ammonia, phosphate and hypoxanthine) after maximal exercise performance in college male students. The experimental trials of each subject were divided into the following conditions: placebo supplement trial and D-ribose supplement trial. The subjects exercised using a Concept II Indoor rowing ergometer for 2,000 m Single Skull event. The subjects ingested 200 mg/kg of D-ribose after breakfast, lunch, dinner, as well as thirty minutes before exercising, for six days. Blood fatigue substances were continuously measured before exercise, immediately after exercise, and thirty minutes after exercise. The results indicated a significant difference in blood phosphate and hypoxanthine levels between the two experimental trials in the 30 minute recovery period (p<0.05). However, there were no significant differences in blood lactate and phosphate levels between the two experimental trials. The results of our study suggest that D-ribose supplementation during maximal rowing exercise for 7~8 minutes may contribute to the improvement of metabolic responses as a beneficial ergogenic aid accelerating fatigue clearance.
