현재 KHCM이 출판될 당시와 현재의 대중교통 환경이 달라져 승하차시간 산정방법이 달라질 필요가 있다고 판단된다. 이에 본 연구에서는 승하차시간에 영향을 주는 승하차수, 입석자수, 상면지상고를 변수로 총승하차시간값을 도출하는 모형을 다중회귀모형을 통해 분석하였다. 그 결과 총승차시간의 경우는 승하차수, 입석자수, 상면지상고 순으로 영향력의 차이가 있었으며, 총하차시간의 경우는 하차자수, 상면지상고 순으로 분석되었고, 두 개의 모형에서의 독립변수들은 모두 종속변수와 양의 상관관계를 가지는 것으로 나타났다. 모형을 통해 예측된 순수 승하차시간은 기존의 버스정류장은 물론 TOD를 고려한 신도시 등의 신설 버스정류장 용량 산정에 유용할 것으로 판단된다.

This study examined the dietary life by residence type of 409 university students (198 male and 211 female) in Chungnam They were divided into five groups according their residence: living in the family home a short distance from the university, living in the family home a long distance from the university, boarding house, self-boarding house, and university dormitory. In this study, the intake of food and nutrients and health, and dietary behaviors of each group were investigated through two-week questionnaire. The average age, height, weight, and BMI were 21.4, 175.3 cm, 68.9 kg, 22.3 in males, and 19.9, 162.3 cm, 53.3 kg, 20.2 in females, respectively. Dietary attitude of the students living in home was higher than that of the other student groups. The rate of breakfast intake and the frequency of eating 10 food items of subjects except processed food of self-boarding house group were lower than those of the other 4 student groups. These results suggest that university students of self-boarding house might have low ability of meal management and more reasonable nutrition education is needed for desirable food behaviors.

This study was performed to investigate the dietary habit based on residence types of male college students who registered nutrition course for nonmajor. Self reports on dietary habit and one-day dietary records were obtained from 158 male college students in Chungbuk area. The distribution of residence type of male college student was as follows; self-boarding(43.0%), home(41.1%), boarding with meal(12.7%), and others(3.2%). The mean age of subjects were $22.6{\pm}2.5$, and the mean height and weight were $175.0{\pm}5.6cm\;and\;69.1{\pm}9.3kg$, respectively. The dietary habit of male college students considered to be taken more care of, showing indifference to dietary balance, irregularity of meal, and skipping breakfast. One-day dietary records by 24hr recall methods also showed less diverse food intake(mean DVS, 12.7; mean DDS, 3.92). Especially, the students with self boarding residence were more likely not to eat properly, including indifference to dietary balance, irregularity of meal, skipping breakfast, frequent dining-out, high experience of smoking and drinking, and low DVS and DDS. Also the students with self boarding residence seemed not to make a good choice for food, showing high food intake frequency score in canned food, fast food and instant ramyun, while low score in fruit and fishes. More attention should be taken for self-boarding students to recognize the problems in their own dietary behavior, and more practical suggestion to improve their dietary status would be necessary.

This study was conducted to investigate the effects of residence types ((1) parent house, (2) dormitory or boarding home, (3) boarding home w/o food) on the dietary habits and health status of college women (20-23 y). Overall, 46.1% of college women reported that they were economically middle class and spent 200,000-390,000 won. Additionally, 17.4% of college women considered themselves healthy, while 33.8% reported that they were not healthy. Furthermore, 32.0% of college women had experience to control their weight and 39.8% reported that they exercised to control their weight. There were no significant differences in the height and weight of the subjects according to residential type, but the amount of skeletal muscles mass ($21.0\;{\pm}\;2.6\;kg$) of the subjects that lived in dormitory or boarding home was significantly higher (p < 0.05) than that of women who lived at home. Additionally, 30.8% of students that lived in private residences, 25.0% of students that dwelled in dormitory or boarding homes and 27.7% of students that boarding home w/o food had three regular meals every day (p < 0.05). It has been reported that 18.3% of college students eat processed and instant foods due to their convenience. In the present study, intakes of energy, protein, fat, vitamin A, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, vitamin C, vitamin E and folic acid for the subjects who lived in dormitory or boarding homes was significantly higher than those of students who lived in private residences (p < 0.05). Additionally, intakes of iron, calcium, and zinc were lower in the subjects that boarding home w/o food (p < 0.05). Finally, the blood glucose level was $84.7\;{\pm}\;13.0\;mg/dL$, and differed significantly by residential types (p < 0.05); however, the average glucose levels of all subjects were within the normal range (90-110 mg/dL).

This study was performed to compare the dietary behaviors of university students in Incheon area by residence types. The population was divided into 4 groups by residence types: family home in Incheon, family home in another area except Incheon, boarding house and, university dormitory. The general subject, health behavior, and dietary behavior of each group were investigated using a one-week questionnaire and the results were as follows. The average height, weight, and BMI were 175.67 cm, 69.8 kg, and 22.61, respectively, for males and 161.84 cm, 51.51 kg, and 19.66, respectively, for females. The most common residence type of the students was the family home in Incheon. Smoking rate of the students living in a boarding house was higher than the other groups. The rate of exercising and consumption of supplements were lower than the other groups. Most of the students frequently skipped breakfast. Boarding and dormitory students missed breakfast more than any of the other groups. The main reason for skipping meals was lack of time. The favorite snack type was confectionery and ice cream. Most of the students had snacks between lunch and dinner or after dinner. The frequency of consuming beans, fruits and, dairy products among 13 food items for boarding and dormitory students were lower than the other groups. The results of this study suggest that nutritional education for university students is needed to improve their dietary behavior and to maintain their health.

This study was carried out with 436 college students in Chungnam to investigate the relationship between residences and eating patterns of college students. The subjects were devided into two groups; those who live in self-boarding house(SB) and home with parents(HWP). The results were as follows. An average height, weight and BMI were 173.5cm, 66.0kg and 21.9 in male SB and 161.8cm, 50.2kg and 19.2 in female SB and 172.9cm, 67.6kg and 22.6 in male HWP and 161.2cm, 50.9kg and 19.6 in female HWP, respectively. There were no significant differences in the general characteristics between the SB and the HWP. The proportions of disease possession, vitamin/mineral supplements and physical exercise were not significantly different between two groups by residences. Sleeping time of the SB was longer than that of the HWP. And, frequency of cigarette smoking and alcohol drinking of the SB were higher than those of the HWP. The proportions of skipping meals in the SB were higher than those in the HWP. Approximately 40.42% of the SB tended to skip the breakfast, while 11.26% of the HWP did. It turns out that the most common reason why skipped meals was due to a eating habit(44.21%) in the SB and a lack of time(48.85%) in the HWP, respectively. The survey shows that while a great majority of the SB had lunch at campus(50.00%) and home(30.00%), the HWP ate lunch at campus(33.79%) and restaurant(33.33%). About 48% of the SB ate out more than 2-3 times a week compared to 42% of the HWP. The daily intakes of calcium, iron, vitamin A, vitamin $B_2$, niacin and vitamin C in the SB were significantly higher than those in the HWP. The percent RDAs of calcium and iron intakes were lower in female students than in male students. In conclusions, students of self-boarding had more dietary problems than students of home with parents. These results suggest that college students of self-boarding might have low ability of meal management. Therefore, nutrition education for college students is needed, and menus of campus cafeterias should be developed to meet the various needs of students.

The purpose of this study was to analyze the quality of meal and dietary habits of college students according to where they reside. This survey included 260 students and was conducted through questionnaires. The subjects were divided into three groups: first group was composed of students who reside in boarding-houses(BH group, N=72), second was students who reside in self-boarding set up(SB group, N=90), and third was those who lived in the same house with their parents(HWP group, N=98). The average age of the students in the BH, SB, and HWP group were 19.7 yrs, 21.1 yrs, and 21.7 yrs, respectively. There were no significant differences in the weight, height and BMI among the three groups. The BH group had significantly higher frequency of skipping breakfast and smoking than those of the SB and HWP groups. The amount of energy, food, carbohydrates, proteins, fats, vitamins and minerals consumed in the BH group were significantly higher than in the SB and HWP groups. Similarly, the NAR(nutrient adequacy ratio), MAR (mean adequacy ratio), ND(nutrient density) and INQ(index of nutritional quality) of the BH group were significantly higher than those in the SB and HWP groups. There was no significant difference in the KDDS(Korean's Diet Diversity Score) between the three groups. From the data obtained, the SB and HWP students appeared to have more dietary problems than the BH students. These results show that nutrition education for SB and HWP students is needed in order for them to learn proper dietary management and help improve the diet of students living in self-boarding arrangements.

In order to investigate the relationship among physical status, eating habits and life style, this survey was carried out by questionnaire in 1996. College students(413 cases) who resided in Chuncheon answered. The results are as follows: 1) The means of height and weight were $173.9\pm{5.0cm}$, $64.5\pm{8.3kg}$64.5$\pm$8.3kg in male students and $160.9\pm{4.5cm}$, $51.1\pm{5.8kg}$ in female students. 2) Under 20 of BMI(Body Mass Index) were 23.0% of male students and 58.3% of female students. 6.7% of males and 3.0% of females were over 25 of BMI. 3) There was a significant relationship between the type of favorite snacks and gender. There was a significant difference of BMI according to the level of the frequency and the amount of drinking alcoholic beverages. 72.6% of subjects took exercise regularly. But the BMI of subjects taking regular exercise and watching the weight tended to be higher than that of subjects not doing so. 4) Most students(78.5%) skipped breakfast, which was higher in the self-boarding students in than any other. It was because of the lack of time that they skipped their meals. This study suggests that a comprehensive nutrition education program is needed for college students in self-boarding houses and dormitories to improve their eating habits about skipping meals, and especially for female students to prevent inappropriate weight control.

This study was performed to compare dietary behaviors based on residence types of female college students. Self reports on dietary behavior and one-day dietary records were obtained from 227 female college students using anonymous questionnaires. The mean age of the subjects was $20.4{\pm}1.43$, and the height and weight were $162.5{\pm}4.8cm$ and $52.3{\pm}7.9kg$, respectively, The dietary behavior of female college students was inadequate, showing indifference to dietary balance, irregularity of meals, skipping breakfast, and high experience of drinking. One-day dietary records were obtained from 24k recall methods also showed a high number registering skipped meal status ($55.3\%$) and less diverse food intake (DVS, 12.5; DDS, 3.93). The students in self boarding residence were especially more likely not to eat properly and their dietary behaviors were found to be significantly poor. In the case of home residence, food intake frequency scores for milk and dairy products, fruits, and fishes were significantly higher, however the students in self boarding residences showed high food intake frequency scores in salted food, retort food, canned food, and especially instant ramyun. Therefore, more attention needs to be given to them to recognize the problems in their own dietary behaviors and more practical nutritional supports, like developing a menu for breakfast in college cafeterias, would be helpful to improve their dietary choices.
