This study was carried out to investigate the relationship between the food and nutrient intake status and eating-out practices of college students. A dietary survey of 361 subjects living in urban areas was conducted by using a 3-day diet record method. The average ages of the male and female subjects were 22.0 and 20.6 years old, respectively. Monthly personal expenses of the male and female students were 316,517 won and 296,888 won, respectively. 43.1% of the male and 50.8% of the female students used between one-quarter and one-half of their monthly personal expenses for eating out. Sixty-five percent of the total subjects ate out more than five times a week The average daily total food intake was 1630.7g in the males and 1453.9g in the females. The average percentage of total food intake from eating out (by weight) was 60.6% in the males and 56.2% in the females; foods eaten out were mainly potatoes, meats, processed foods, and beverages. It was found that 40-65% of daily total nutrient intake came from food eaten out. When they ate out, the male students ate slightly higher amounts of protein, fat and vitamin B1, while the female students ate relatively higher amounts of animal protein, fat, vitamin A and cholesterol. The more the subjects ate out, the more the quantity of total food intake increased. This increase resulted from high intakes of beverages and processed foods in the males, while the increase was from total plant foods, mushrooms, beverages, and milk and dairy products, in the females. The dietary variety score (DVS) was significantly increased in the female subjects when they ate out more than once a day; otherwise, the DVS was not significantly different between any of the male and female groups. The intakes of energy, and of many nutrients such as protein, fat, carbohydrates, calcium, phosphorus, iron, potassium and cholesterol, were increased when the female subjects ate out more than twice a day. The mean adequacy ratio (MAR) was at its highest level of 0.65 in the males when they ate out less than once a day, and at its highest level of 0.67 in the females when they ate out more than twice a day.

하잠기와 초추잠기에 각주마다 뽕나무지조중 잔가지와 정상가지 2개씩을 솎아베기하였을 경우에 가지의 발육과 수량에 어떤 영향을 미치는가를 조사한바 다음과 같은 결과를 얻었다. 1) 봄베기한 뽕나무에 있어서 하잠기에 솎아베기를 하고 추잠기(이 기간 42일간)에 수확을 한 경우에 있어서 (1) 추잠기까지에 그 평균조장이 19% 가 증가하여 솎아베기를 하지않은 경우의 증가율 8% 보다 11% 나 그 증가비율이 높았다. (2) 솎아베기를 하면 이것을 하지않은 경우에 비하여 하잠기와 추잠기의 합계수량에 있어서 유의성은 없지만 9% 정도 증수가 된다. 2) 여름베기한 뽕나무에 있어서 초추잠기에 솎아베기를 하고 추잠기(이 기간 15일간)에 수확을 하는 경우와 만추잠기(이 기간 29일간)에 수확을 하는 경우에 있어서 (1) 그 평균조장은 솎아베기를 한 경우나 하지않은 경우나 다 같이 추잠기까지는 6∼7%, 만추잠기까지는 8% 정도 증가하여 솎아베기의 효과를 인정할 수가 없었다. (2) 초추잠기와 추잠기의 합계수량은 솎아베기를 한 경우가 하지않은 경우에 비하여 6%가 증수가 되어 유의성은 없지만 증수의 경향이 있고 초추잠인와 만추잠기의 합계수량은 솎아베기를 한 경우가 하지않은 경우보다 12%가 단수가 되어 5%의 수준에서 유의성이 인정되었다. (3) 솎아베기가 평균조장의 증가에는 별로 효과가 없지만 수량증가에는 효과를 나타낸 것은 솎아베기를 하므로 말미암아 뽕나무주내의 생활조건을 개선하여 광합성작용을 왕성하게 하므로써 엽중을 증가시킨 까닭이라고 생각된다.

단일 교환기로 다양한 유형을 효율적으로 지원할 수 잇는 멀티캐스트 교환기는 광대역 종합망의 성공적인 확산에 필요 불가결한 요소이다. 본 논문에서는 멀티캐스트 교환기에서 이질적 트래픽이 혼합된 환경을 가정하고 회선 에뮬레이션 트래픽의 성능을 분석하였다. 기존의 연구에서, 모든 호가 동일한 fan-out을 갖는 동질 트래픽 환경에서 fan out이 증가함에 따라 호 불통률이 급격히 증가하는 것이 관찰되었다. 본 논문에서는 fan-out이 서로 다른 호가 혼합된 이질 트래픽 환경에서는 fan-out에 따른 호 불통률 차이가 동절 트래픽 경우보다 오히려 증가하는 결과를 도출하였다. 이 결과는 멀티캐스트 교환기에서 멀티캐스트 호의 성능을 향상시키기 위한 효율적인 자원 할당 알고리듬을 사용해야 한다는 것을 지적하고 있다. 본 논문에서는 멀티캐스트 교환기의 성능을 향상시킬 수 있는 몇가지 방안을 제시하였다.

The purpose of this study was to confirm the effects of flush-out in the reduction of formaldehyde concentration in newly built residential buildings. The field measurements were conducted on two complexes of multi-residential buildings which are located in the suburban area of Seoul. About eight samples of residential buildings were selected to measure the changes in formaldehyde concentrations after flush-out from the two apartment complexes. The concentration of formaldehyde was measured using DNPH cartridge and HPLC. From the results of the field measurements, it was established that indoor formaldehyde concentration decreases 27.6~54.2% in the samples after flush-out. The number of days that the flush-out were conducted was noted to have no significant influence on the reduction rate of formaldehyde concentration when the flush-out continued more than 7 days. The comparison with Bake-out showed that flush-out also can reduce formaldehyde in newly built buildings as same levels of it.
