Objectives : The study is to gain some basic material for the improvement of dental clinics' homepages through a survey investigation, in which college students of three Dental Hygienic departments participated in Kwangju and Cheollanamdo Province. Methods : In the investigation three factors were analyzed : the degree of knowledge on dental clinics' homepages, the degree of recognition on them, and whether they have paid a visit on them or not. A total of 509(96.8%) respondents are valid except 17sheets of responses. Results : 1. When asked about the degrees of knowledge on the formation of the homepages by students' years, the correct rate on Information Service was higher in a row of the second year, the first year, and the third year. And it shows statistically significant difference(p<0.05). In the part of Counseling Service, the rate of correct answers was highest in the second year, and then the first year and the third year. It also shows significant difference(p<0.05). In case of Visual Service, the second year got the highest rate of correct answers, and then the first year and the third year. Here is significant difference by the school years<0.01) 2. It was asked whether they have visited the dental clinics' homepages. The results are like this: 145 sophomores(28.5%) have visited them, and 115 juniors(22.6%) and 85 freshmen(16.7%), and it show significant difference (p<0.001). 3. It was asked how many sites they have visited. Among the freshmen, not a few students visited two sites (34, 9.9%), among sophomores 48 students visited five sites(13.9%), and among juniors the highest answers were two sites (41, 11.9%). It shows signigicant difference(p<0.01). 4. It was asked what is the purpose of the visits. At this 27 freshmen answered for having counseling(7.8%), and 80 sophomores(23.3%) and 43 juniors(12.5%) answered they visited them for the purpose of gaining some materials about their major. It shows significant difference(p<0.001). 5. It was asked with what opportunity they have visited them. They answered through searching activities like this : freshmen (68, 19.8%), sophomores (130, 37.9%), and juniors (98, 28.6%). It shows significant difference(p<0.05). 6. In regard with the recognition of the homepages, all the participants said that the management of the homepages are closely related with the images of the clinics($3.96{\pm}0.781$). But it is found that they do not think that the effective management of dental clinics' homepages is the task of dental hygienic workers as a part of dental hygienic($3.12{\pm}0.971$). 7. There is some difference concerned with the homepages among each group of students; sophomores have highest recognition on them and then juniors and freshmen, and it shows significant difference(p<0.01). In addition, those who have visited them show higher recognition than those who have never visited them(p<0.001). Conclusions : There are some differences among each group of students in regard with the formation service, the purpose of visiting them and such experiences, and the opportunities. Whereases they think that the management of the homepages are closely related with the images of the clinics, they do not think that the effective management of dental clinics' homepages is the task of dental hygienic workers as a part of dental hygienic. Therefore it is necessary to study actively for the qualitative improvement of the dental clinics' homepages, which will result in the higher recognition on the homepages by the dental hygienic students and the workers.

The most important task in Korean dairy industry is to keep the seasonal and annual balance of raw milk supply and demand. Too much surplus milk supply which causes dumping sale of market milk makes dairy industries get in trouble of management, and eventually affects to farmers and consumers economically. As balancing of supply and demand is so important in the fee economic market system, the adaption of the quota system of milk production and seasonal price differentiation has been recommended very often as a method of controlling the milk supply and demand. However, this recommendation did not go through successfully due to the strong objection of dairy farmers. Recently, the voice of consumer's requirement for safer and more hygienic, and high protein, low fat level dairy product is getting stronger. By knowledge of this kind changes, quality improvement in nutrients and hygiene is the most positive way to expand the volume of milk consumption. To meet the consumer's demand, therefore, it is necessary to revise the level of milk fat content and the hygienic grading system for the payment system of raw milk.

외식산업의 빠른 성장과 함께 호텔을 비롯한 일반음식점에서의 식중독의심사건 발생빈도가 증가하고 있어 현장에서 신속하고 간편하게 위생상태를 판단할 수 있는 모니터링기법이 필요하게 되었다. 본 연구는 서울시내 5개 호텔을 대상으로 개인위생 (작업자의 손), 조리기구 (칼, 도마, 행주, 캔오프너, 식품보관용기, 슬라이스머신칼날), 시설 설비 (냉장고손잡이, 작업대, 싱크대)에 대한 위생관리 실태를 조사하였고 그에 대한 검증법인 ATP 조사법의 상관관계를 도출하고자 하였다. 5개 호텔의 위생관리 실태조사 결과, 50점 만점 중 개인위생 46.6점, 조리기구 위생관리 40.2점, 시설 설비 위생관리 40.3점으로 개인위생은 비교적 관리가 잘 되고 있었으며, 조리기구와 시설 설비의 위생관리는 미흡한 것으로 나타났다. ATP검사 결과, 작업자의 손은 $40.8{\pm}6.77\;RLU/cm^2$로 조리기구와 시설 설비에 비해 높은 값을 보였으나, 모두 1,000 RLU/$cm^2$의 기준 이하로 위생관리 상태가 양호한 것으로 나타났다. 위생실태조사 결과 점수와 ATP 값의 상관성 분석을 실시한 결과, 각 호텔별 작업자 손, 조리기구, 시설 설비 모두에서 음의 상관관계를 가지며 높은 상관성을 보였다 ATP검사법은 신속, 간편, 일관성을 바탕으로 호텔을 비롯한 외식업체에서 감시원이 수행하는 주관적인 위생실태조사를 대체 할 수 있는 객관적인 위생관리 방법이 될 것으로 판단된다.
