         <description><![CDATA[<p><strong>[OSEN=임영진 기자] 한 계단만 올라서면 정상이다.</strong></p><p><br/></p><p>가수 싸이가 미국의 권위있는 음악 사이트 빌보드가 집계해 발표하는 메인차트에서 2위를 차지했다. 빌보드 측은 “싸이가 가파르게 치고 올라오고 있어 다음 주 중 정상의 자리에 오를 것”으로 내다봤다.</p><p><br/></p><p>빌보드는 27일(한국시간) 새벽 주요 차트인 핫(Hot)100의 순위를 정리해 발표했다. 공식 게재는 하루 뒤인 28일 이루어지지만 순위 발표는 이에 앞서 수반됐다. 빌보드 측은 “싸이의 ‘강남스타일’이 2주 전 64위로 빌보드 핫100에 진입한 데 이어 2주 만에 11위를 거쳐 2위로 급상승했다. 마룬파이브의 자리를 위협하고 있다”고 밝혔다. 마룬파이브는 ‘원 모어 나이트(One More Night)’로 1위를 차지했다.</p><p><br/></p><p>이어 “세계적으로 히트하고 있는 ‘강남스타일’은 차트 내에서 순위가 치솟고 있다. 이번 주 집계에 따르면 ‘원 모어 나이트’와 ‘강남스타일’ 간 점수 차가 좁아 다음 주 ‘강남스타일’이 정상에 들 수 있을 것”이라고 예상했다.</p><p>미국 음반시장의 변화를 가장 빠르게 체감할 수 있는 아이튠즈 차트에서도 싸이는 지난 15일부터 무려 11일간 차트 정상을 차지하는 기록을 세운 바 있다. 27일 오전 현재 ‘강남스타일’은 아이튠즈 차트 2위를 달리고 있다</p><p><br></p>]]></description>

         <description><![CDATA[<p><strong>[마이데일리 = 안경남 기자] "사실 손 맞고 들어갔어요."</strong></p><p><br/></p><p>독일의 스타 스트라이커 미로슬라브 클로제(라치오)가 또 한 번 페어플레이 정신을 발휘해 시선을 끌고 있다. 클로제는 지난 27일(한국시각) 벌어진 이탈리아 세리에A 나폴리와의 원정경기에서 손을 사용해 득점을 한 뒤 심판에게 이 사실을 털어놓으며 자신의 득점을 무효로 만들었다.</p><p><br/></p><p>경기 시작 4분, 동료가 쏜 코너킥을 골키퍼 바로 앞에서 장기인 헤딩슛으로 연결시켜 골망을 흔들었다. 하지만 실제로 공은 클로제의 머리가 아니라 손에 맞았다. 마라도나의 '신의 손' 장면과 흡사했다.</p><p><br/></p><p>골 선언 직후 클로제는 손을 들어 잘못을 시인하려 했지만 동료들이 그를 감싸며 '이적행위'(?)를 말렸다. 하지만 클로제는 나폴리 선수들의 항의가 이어지는 과정에서 재차 심판에게 자신의 반칙을 고백했고 골은 없던 것으로 됐다. 나폴리 선수들은 클로제를 감싸 안았다. 나폴리 주장 파올로 칸나바로는 "상을 받을 만하다"면서 그의 용기 있는 행동을 칭찬했다. 선제골을 잃은 라치오는 나폴리에게 0대3 완패를 당했다.</p><p><br/></p><p>클로제의 '양심선언'은 처음이 아니다.</p><p>그는 독일 브레멘 시절인 2005년 빌레펠트와의 경기에서 골키퍼와 충돌 후 페널티킥을 얻자 "골키퍼가 먼저 공을 터치했다"고 주심을 설득해 팀에게 주어진 페널티킥을 무효화시켰다. 바이에른 뮌헨 시절인 2010년에는 피오렌티나와의 UEFA 챔피언스리그 16강전에서 결승골을 터트린 뒤 경기 후 인터뷰에서 "사실은 그 골은 오프사이드 위치에서 터트린 득점이었다"고 고백해 논란을 일으키기도 했다.</p>]]></description>

         <description><![CDATA[<p>헬륨의 성질</p><p>18족 원소들 중에서 가장 가벼운 헬륨은 공기보다 가벼운 기체로 파티 때 사용하는 풍선에 넣는 기체로 널리 알려져 있다. 모든 와 마찬가지로 색깔이나 냄새가 없고 반응성이 매우 낮다. 헬륨의 안정한 화합물은 알려진 것이 없다. 헬륨은 개개의 원자로 존재하며 모든 원소들 중에서 끓는점과 녹는점이 가장 낮다.</p><p>헬륨의 많은 용도 중 하나가 액체 상태의 헬륨을 이용하는 것이다. 액체헬륨은 MRI의 초전도 자석을 냉각시키는 데 사용된다. 이와 비슷하지만 훨씬 규모가 큰 입자가속기의 초전도체 자석에도 액체헬륨이 사용된다. 그리고 기체 상태의 헬륨은 입자의 충돌로 발생한 열을 제거하기 위해 사용된다. 우주공학에서는 액체헬륨이 로켓 연료로 사용되는 수소와 연료를 연소시키는 데 필요한 산소를 액화시키고 발사 전까지 차갑게 유지하는 데 사용된다.</p><p>헬륨을 가지고 노는 재미있는 방법 중 하나는 파티용 풍선에서 헬륨 기체를 들이마셔 목소리가 이상해지도록 만드는 것이다. 사람들의 예상과는 달리 헬륨을 마신다고 목소리의 진동수가 변하는 것은 아니다. 사람의 성대는 공기 속에서나 헬륨 속에서 똑같은 진동수의 목소리를 낸다.</p><p>그러나 소리의 속도는 헬륨 안에서 훨씬 더 빠르기 때문에 입이나 코 안의 공간이 줄어 든 것과 같은 효과를 내 더 높은 진동수를 가진 소리가 공명하도록 한다. 헬륨은 독성이 없기 때문에 한 모금 마시는 것은 해롭지 않지만 계속 마실 경우 죽음에 이를 수도 있다. 허파가 헬륨으로 가득 차면 산소가 몸의 조직에 공급되지 못해 질식할 수 있기 때문이다.</p>]]></description>
