터질 듯 붉게 익은 홍시는 보는 것만으로 구미를 당긴다. 홍시는 맛이 달뿐만 아니라 건강에도 좋은 건강식품이다. 숙취해소에도 좋고, 고혈압을 비롯한 각종 질환에도 효과적이다. 꼭지는 딸꾹질을 멈추는데 쓰이기도 한다. 단풍이 들면 화사한 빛깔을 자랑하는 잎은 달여서 차로 만들 수 있다. 이렇듯 무엇 하나 버릴 것 없는 감의 무궁무진한 매력을 소개한다.

We performed simulations of shipping conditions to export 'Cheongdobansi' astringent persimmon to tropical regions. We stored the fruits at $0^{\circ}C$, $5^{\circ}C$, or $10^{\circ}C$ temperature for 15 days to simulate the transport conditions, and then maintained the fruits at $30^{\circ}C$ for 5 days to simulate the distribution condition. Variables that we focused on are 1) the transport temperature($0^{\circ}C$, $5^{\circ}C$, or $10^{\circ}C$) and 2) the treatment time of ethylene generator(before or after shipping). We examined the ripening ratio and quality of the fruits at the end of the shipping and at that of the distribution. The examination at the end of the shipping showed that all of the fruits were ripened at $10^{\circ}C$ transportation but not ripened at $0^{\circ}C$ or $5^{\circ}C$ transportation in the ethylene treated condition. The untreated fruits were not ripened regardless of the transportation temperature. The examination at the end of the distribution showed that all of the fruits were ripened at $5^{\circ}C$ and $10^{\circ}C$ transportation, while 38.5% of fruits were ripened at $0^{\circ}C$ transportation in the ethylene treated fruits before shipping. The fruits treated after shipping were 63.5% and 59.6% ripened at $0^{\circ}C$ and $5^{\circ}C$ transportation, respectively. Unexpectively, only 19.2 % of fruits treated after shipping ripened at $10^{\circ}C$ transportation.

고수동굴은 현재까지는 관광개발된 석회동굴 중 가장 많은 관광객을 유치하고 있을뿐만 아니라 이 동굴개발에 따른 주민들의 소득증대는 단양지구의 생활향상에 크게 이바지되고 있는 관광자원이다. 이 동굴의 첫 학술조사는 1973년 10월에 한국동굴학회학술조사단 (단장 : 홍시환)에 의하여 실시되었으며 그후 우리나라 천연기념물 제 256호로 지정받게 되고 학교법인 유신학원(이사장 : 박창원)에 의하여 마침내 우리나라 제일가는 관광동굴로 개발하기에 이르렀다. (중략)
