Universal designs begins from observing things. This paper understands contradiction and irrationality about drink bottle used unintentionally in our common life. Those have not found out until now. So an example observation about problem derivation and a practice method of Universal design is presented. People of various classes, such as a child, an old person and a woman, a male, the man in the street, and a disabled person, have been using drink bottle recently. However, the design of drink bottle has become on the basis of the fine and common man, so the other people, for example, children or handicapped persons experience many situations which cannot open cap or cannot be drunk without external help. This research posed questions from the children to the elders about drink bottle by the viewpoint of universal design paying attention to such problems. In the research result, the fixed quantity and qualitative quantity about problem are commented. And the fixed quantity utilized frequency analysis and chi-square verification ($X^2$) for the questionnaire result on the basis, and the qualitative quantity pointed out result in the universal design principle through the data of a precedence research result. An alternative plan for drink bottle's design is presented through case observation of conceptual approach to method of Universal design.

In general, forest tending work contributes to preventing landslides by enhancing forest health. In order to quantify beneficial effects of forest tending, landslide occurrences in forest tending area and those in non-forest tending area were compared and analyzed. The landslide had been hit hard in Inje and Pyeongchang county, Gangwon province, following Typhoon 'Bilis' on July 15, 2006. Data on forest tending of Pinus koraiensis and Larix kaempferi stands were acquired from the Inje National Forest Station, North regional forest service. The rate of landslide occurrence was increased sharply just after forest tending work and was decreased as time goes by. The analysis also found that the change in landslide frequency was slight by age class in the non-forest tending area, while it decreased as age class increased in the forest tending area.

현대 사회에서 심장 질환은 3대 사망요인 중 하나로 매우 위험한 질환으로 분류되고 있으며 이에 의한 사망률이 매년 증가하는 추세이다. 기존의 의학적 상식에 의하면 스테로이드계의 남성 호르몬인 테스토스테론은 심장 질환과 관련이 있다고 되어 있다. 테스토스테론은 남성에게 중요한 호르몬으로 적당량이 분비되어야 건강하지만 너무 적게 분비가 되면 남성에게 있어 여러 가지의 병의 원인이 된다. 이와 같은 테스토스테론은 남성의 무명지의 길이에 영향을 주는데 분비량에 비례하여 무명지의 길이가 검지에 비해 길어진다. 따라서 본 논문에서는 심장 질환자와 정상인의 무명지 길이와 검지 길이를 비교, 분석하여 무명지의 길이와 심장 질환의 상관관계를 분석하였다.

The purpose of this study was to evaluate nutrition knowledge and utilization of information on fast food of secondary school students in the two biggest cities, Seoul and Busan. Questionnaires were distributed to a total of 1,265 students (645 at 10 middle schools, 620 at 10 high schools). An average rate of correct answers on nutrition knowledge of fast food was 73.4%. General nutrition knowledge on fast food showed high percentage of correct answers, but the knowledge of vitamin and fiber on fast food was of low percentage. The scores of nutrition knowledge, the fast food (ie. chicken, pizza, gimbab, dukbokki, and ramyon) intake group with $'{\geq}1$ time/week' showed significantly (p<0.01) lower scores than those of the group with $'{\leq}1$ time/month'. The groups with higher interest in health and weight control had significantly (p<0.05) higher scores on nutrition knowledge than those of lower interest groups. Only 19.6% of the subjects had the experience of using the nutrition information for selecting fast food, but 66% of them wanted the developments of the internet-sites to provide information on fast food and on the relationship between fast food and health.
