본 연구는 중년 여성을 대상으로 생활습관에 따라 골밀도와 체력에 미치는 영향을 분석하여 운동프로그램에 관련된 유용한 정보를 제공하는데 목적이 있다. 연구를 수행하기 위하여 C보건소를 내원한 여성 331명을 운동습관에 비운동군, 저빈도운동군(주당 2회 이하 운동), 중정도운동군(주당 3회 이상)으로, 음주습관에 따라서는 비음주군과 저음주군(주당 음주), 고음주군(주당 이상), 염분섭취수준에 저염식이군, 중염식이군, 고염식이군으로 각각 분류하였다. 측정변인은 최대산소섭취량, 체지방률, 악력, 유연성, 민첩성, 평형성으로 하였으며, 집단간 차이를 검증하기 따라서 one-way ANOVA를 실시하였다. 운동습관이 많을수록 골밀도는 유의하게 높았으며, 체지방률은 낮게 나타났다. 음주습관과 따른 골밀도 및 체력은 유의한 보이지 않았지만, 염분섭취가 체중과 체지방이 증가하는 경향을 보였다. 결론적으로 규칙적인 운동은 체력유지에 도움을 주며, 고염식이는 체중증가의 요인이 될 수 있을 것으로...

지적장애인은 인지기능과 조정기술의 손상, 낮은 운동능력 등으로 인해 신체활동수준이 부족하고 음식섭취 욕구가 강하여 생활습관질환의 이환율이 높아 삶의 전 영역에 영향을 미친다. 안타깝게도 현대의학으로는 지적장애인의 질을 개선시키기에는 많은 어려움이 있다. 하지만 규칙적인 신체활동은 이러한 문제점을 개선시키는 중요한 중재로 인정되고 본 연구는 유희성과 중독성이 있는 가상현실 게임프로그램을 통한 운동프로그램과 일반적인 빠르게 걷기 프로그램을 통해 건강관련체력과 정신건강수준 등을 비교하였다. 중도탈락자를 제외하고 게임운동프로그램군 5명, 운동프로그램군 4명을 대상으로 비모수검증을 비교분석하였다. 게임바이크운동프로그램군의 체중, 근지구력 요소에서 유의한 개선이 있었으며, 모든 집단의 중성지방, 유연성, 최대산소섭취량, 운동지속시간에서는 통계적으로 유의하지는 않았지만 개선되는 경향을 보였다. 운동프로그램 전·후 우울, 사회적 부적응, 정신건강에서는 운동프로그램군에 비해...

This paper proposes a cooperative environmental learning algorithm working in fully distributed manner. A multi-robot system is more effective for exploration tasks than single robot, but it involves the following challenges: 1) online of map using multiple robots; 2) generation safe and efficient path based on learned map; 3) maintenance scalability with respect to number robots. To this end, we divide entire process into two stages planning. Distributed algorithms are applied each stage...

As many DERs with solid grounding are connected to the distribution system, unwanted reverse fault current is generated during a single-line-to-ground fault. Therefore, it often causes protection problems such as blinding and sympathetic tripping. To ensure reliable coordination between protective devices, should be calculated accurately. Although three-limb core transformers utilized for economic spatial reasons, conventional method that assumes five-limb still used calculate current. The...
