The purpose of this study were to investigate a study of body composition, physical fitness, change of vascular compliance and nutrient intake status a before and after bodybuilders match. In this study, participants were 6 bodybuilders. The analyzed data brought about the following results by using paired t-test with SPSS 20.0. The results of the research were as follows. In to body weight and BMI were significantly increased but sit and reach were significantly decreased after match. There was non significantly difference in vascular compliance. Calories, lipids, carbohydrates, fiber and ash had significantly increased after match than before match. Calcium, iron, sodium, potassium, vitamin A, retinol, vitamin B1, vitamin B6, niacin, vitamin C, vitamin E had significantly increased after match than before match. Therefore, Bodybuilders need correct regular diet habit and exercise prescription after match. 본 연구는 B광역시 남자 보디빌딩 선수 6명을 대상으로 신체조성, 체력, 혈관탄성도 및 영양소 섭취상태를 시합 전·후를 분석하는데 목적이 있다. 자료처리는 SPSS 20.0 프로그램을 이용하여 paired t-test를 실시하였고, 연구결과에서 다음과 같은 결론을 얻었다. 시합전에 비해 시합후에 체중과 BMI는 유의하게 증가하였고, 유연성은 유의하게 감소하였고, 혈관탄성도는 유의한 변화가 없었다. 그리고 열량, 지질, 당질, 식이섬유 및 회분은 시합 전 보다 시합 후 유의하게 증가하였다. 또한, 칼슘, 철분, 나트륨, 칼륨, 비타민 A, 레티놀, 비타민 B1, 비타민 B6, 나이아신, 비타민 C, 비타민 E는 시합 전 보다 시합 후 유의하게 증가하였다. 이상을 종합하여 볼 때, 시합 전보다 시합 후에 영양소의 섭취증가로 인해 체중이 증가하는 것을 알 수 있으며, 이상의 연구 결과에서 시합전, 후의 식습관, 맞춤형 운동처방 및 체계적인 컨디셔닝 관리가 요구된다.

Lead-free (K,Na)NbO3 Thick Films for Flexible Non-volatile Memory Applications

Kwak Yeong Min,Lee Tae Kwon,Kong Dae Sol,Ko Young Joon,Jeong Dong Geun,Jung Jong Hoon 한국물리학회 2020 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.77 No.9

We report the sol-gel fabrication and electrical characterization of flexible (K,Na)NbO3 (KNN) thick films. Muscovite mica allows the growth of high-quality polycrystalline KNN thick films with flexible functionality. Because of the trade-off between increase of grain-size and volatilization of alkaline ions, the electrical polarization is optimized at certain temperature of 720 °C. The remnant and saturation polarization of flexible KNN films were recorded to Pr=10.3 μC/cm2 and Ps = 23.3 μC/cm2, respectively, which are quite close to those of rigid films with the same chemical compositions. The KNN thick films are bendable even up to bending radius of R = 3.1 mm, and the Pr and Ps at bending states are almost the same as compared to those at unbending state. Even in the convex and concave bending, the KNN thick films show excellent non-volatile memory characteristics. The Pr is almost the same even after the 108 times of switching and the 104 sec of retention.

실험동물은 생후 4주령 Sprague Dawley계 수컷 흰쥐 24마리로 흑마늘운동군(6마리), 운동군(6마리), 흑마늘군(6마리), 대조군(6마리)으로 총 24마리로 구분하여 운동은 총 4주간 트레드밀로 실시하였으며, 시료 채취 하기 바로 직전에 고강도 운동을 실시하였다. 흑마늘 섭취는 흑마늘진액을 구강 투여시켰으며, 연구결과 다음과 같다. 4주간의 흑마늘 투여와 유산소운동 후 고강도 운동을 실시하였을 때 TBARS 농도는 흑마늘운동군이 흑마늘군, 운동군과 대조군에 비해 유의하게 낮았다. 흑마늘군과 운동군은 대조군에 비해 유의하게 낮았다. HSP 70 발현은 흑마늘섭취군이 다른군에 비해 상대적으로 낮게 나타났다. COX-2 발현은 모든군에서 비슷한 발현을 보이고 있으며 규칙적인 운동과 흑마늘 섭취는 산화적 스트레스를 줄일 수 있을 것으로 기대된다. The purpose of this study was to investigate the effects of black garlic supplementation and exercise on TBARS, HSP 70, and COX-2 expression after high-intensity exercise in rats. Twenty-four male Sprague-Dawley rats (4 weeks) were used in this study. Experimental groups were a control group (A, n=6), black garlic supplementation group (B, n=6), exercise group (C, n=6), and black garlic supplementation with exercise group (D, n=6). High-intensity exercise was performed by treadmill running (every 10 min speed increased gradually; 15~24 m/min, 0° grade) and 2.86 g/㎏ black garlic for 4 weeks. The findings of this study were as follows: TBARS levels were significantly lower in the D group compared to the other group and B and C groups were significantly lower in TBARS levels than in the A group. HSP 70 expression was lower in the B group compared to the other groups. COX-2 expression has showed a similar expression in all groups. Therefore, it is considered that black garlic intake and exercise may reduce oxidative stress.

Min Yeong Kwak 위기관리 이론과 실천 2018 Journal of Safety and Crisis Management Vol.8 No.2

The purpose of this study was to make the concept of resilience as a basis of nursing practice, research and education related to stress response and adaptation by analyzing and clarifying the concept analysis procedures of Walker & Avant (2005). This study compiled the concept of resilience by reviewing and defining its meaning and drew three properties. The identified attributes were first, the measure of adversity itself, secondly, internal and external characteristics of individuals, thirdly, psychosocial health, achievement of developmental tasks, and satisfaction with life. The results are expected to serve as basic data onto intervention to strengthen the resilience of individuals as well as communities.

본 연구는 최근 우리나라에서 중요성이 부각되고 있는 소방공무원의 외상후 스트레스 예방 및 관리를 위하여 1차 예방교육, 2차 조기발견 및 치료를 위한 개인상담과 집단요법 및 3차 추후관리를 위한 사례관리 프로그램의 3단계로 구성되어진 통합 프로그램을 개발하고 이 프로그램을 실시한 후, 소방공무원들의 외상후 스트레스, 우울 및 수면장애에 미치는 효과를 검정하고자 하였다. Y시의 소방공무원 170명을 대상으로 한 본 연구에서 개발된 프로그램 시행 후 외상후 스트레스, 우울 및 수면장애의 점수가 유의하게 감소하여 프로그램의 효과가 검정되었다. 따라서 일선 현장에 본 연구에서 개발된 외상후 스트레스 통합관리 프로그램을 통한 개인적, 집단적 접근을 통하여 지속적이고 체계적인 심리지원서비스를 제공함으로써 소방공무원의 외상후 스트레스, 우울 및 수면장애를 경감시키는 중재 프로그램으로 활용할 수 있을 것이다. 향후 이 프로그램이 소방공무원의 실무에서 확대 보급되어지고, 중재기간에 따른 효과와 지속성을 검정하는 종단적인 연구가 지속되어져, 소방공무원들의 외상후 스트레스 관리를 위한 체계적인 정책수립이 수반되기를 제언한다. This study intends to develop an integrated program to prevent and manage post-traumatic stress disorder (PTSD) firefighters may suffer, which enhances their mental health based on their working level (individual or group). It examines the effect of this program on post-traumatic stress, depression and sleep disorder of 170 firefighters working at a fire station in Y city in Korea. The data were analyzed with SPSS (Win 18.0) utilizing frequency, percentage, average and a paired t-test. The results of the study showed that the post-traumatic stress, depression and sleep disorder scores were significantly decreased after the program. Therefore, the integrated management program for PTSD among firefighters can effectively maintain psychological stability through systematic and continuous engagement with psychological support activities. Firefighters can also be useful in maintaining a healthy lifestyle, preventing progression to PTSD, be useful in alleviating the secondary pathologies, and prevent the ripple effect of your organization through systematic management.

The green rice leafhopper (GRH), Nephotettix cincticeps Uhler, is one of the most serious insect pests affecting cultivated rice (Oryza sativa L.) in temperate regions of East Asia. To understand the genetic basis of the GRH resistance, a F2 population derived from across between a highly resistant variety,Cheongnam and a susceptible variety, Junambyeo was analyzed by genetic analysis and association mapping. GRH resistance was evaluated using the F2 populations. The results showed that a single dominant gene in Cheongnam. DNA from 22 F2 individuals being either resistant or susceptible were pooled to produce bulk resistant and bulk susceptible DNA samples. Parents and bulks were screened with 192 SSR markers and twolinked SSRmarker, RM6082 and RM20145 were identified.Subsequent mapping in the original mapping population showed that thelocusis flanked by the SSR markers, RM20130 and RM20152 on chromosome 6. To physically map this locus, the-linked markers were landed on the artificial chromosome clones of the reference cv., Nipponbare, released by the International Rice Genome Sequencing Project. The DNA markers found to be closely linked to Grh3 would be useful for marker-assisted selection for the improvement of resistance to GRH in rice.

서남해 해상풍력 실증단지 건설의 기초단계로 실증단지 예정부지에서 해상작업가능시간을 산정하고 분석하였다. 활용 자료로는 해모수 기상타워의 해양 및 기상자료와 기상청 수치모델 자료이다. 해상작업이 가능한 파고와 풍속 기준을 선정하고 기준별 작업시간을 산정한 결과 계절적으로는 고파랑이 지나가는 겨울의 작업시간이 봄, 가을보다 적은 것으로 나타났고 여름의 경우 작업시간이 가장 많은 것으로 나타났다. 그러나 월별로는 7,9월보다 5,6,8월에 가장 많은 작업시간이 나타났다. 그리고 파고1.5 m와 풍속 8 m/s 이상의 기상조건에서는 파고와 풍속이 증가하더라도 작업시간은 크게 변하지 않는 것을 확인할 수 있었다. As a preparation process for successful establishment of demonstration offshore wind farm, analyses have been made for working time at the construction site where working time is defined as the time available for marine operation to take place under given weather conditions. Data used are hourly wave and wind data from met mast, HeMOSU-1, and 3 hour numerical model data from Korea Meteorological Administration (KMA). Seasonal results show the minimum working time during winter and moderate during autumn and spring. The most working time was seen during summer on average. Monthly analyses show the most working time in May, June, and August which was higher than the working time in July and September. Working time reaches at steady state and no significant change was seen above wave height of 1.5 m and wind speed of 8 m/s.
