The study investigates weekday/weekend characteristics of $PM_{10}$ and $PM_{2.5}$ concentrations and meteorological elements in Busan. The $PM_{10}$ concentration is highest on Wednesday and Thursday, and lowest on Sunday. On the other hand, the $PM_{2.5}$ concentration is highest on Wednesday and lowest on Sunday. The location where concentrations of weekdays and weekend differ the most is Hwakjang-dong, the industrial area, and where they differ the least is Gijang-up and Joa-dong, the residential area. Fine particle concentration in the industrial area was consistent at dawn and in the morning, but varied in the afternoon and at night. The visibility of Sunday was 0.49 km higher than that of weekdays, and the solar radiation of Sunday was $0.11MJ/m^2$ higher than that of weekdays. These results indicate that the concentration of fine particles had influence on the change of visibility and solar radiation.

이 연구는 SBS 수목드라마에서 나타난 등장인물의 행위들에서 만들어 내는 다양한 관계들이 어떻게 소통되고 있는지를 그레마스 행위소 모델을 통해 의미를 분석하고자 하였다. 주체와 대상의 관계에서 주체가 가지고 있는 결핍구조를 분석하여 이러한 관계에서 발생하는 문제들을 살펴본다면 서로 다른 장르에서 나타나는 드라마 속의 등장인물 관계를 종합적으로 분석할 수 있다. 이를 해석해보면 같은 사건에서 시작된 발신된 주체와 대상의 결핍 구조는 다르게 나타난 반면, 우연한 사건으로 인한 주체와 대상은 같은 결핍구조를 가지고 있었다. 주체와 발신자의 관계에서는 주체보다 나약하고 보호 받아야하는 불쌍한 인물들로 설정되었을 때는 극중 역할이 제한적이지만 발신자가 주체에게 적대자로써의 역할을 같이하는 구조에서는 주체보다 권위적이었다. 세 작품 속에서 나타난 반대자들은 결국 주체와 대상에게 또 다른 협력자들로 변절하며 사건 해결에 도움을 주며, 불행해지기보다는 한결 더 성숙해지는 경향이 있었다.

The purpose of this study is to find the factors that reduce prediction error in traffic volume using highway traffic volume data. The ARIMA model was used to predict the day, and it was confirmed that weekday and weekly characteristics were distinguished by prediction error. The forecasting results showed that weekday characteristics were prominent on Tuesdays, Wednesdays, and Thursdays, and forecast errors including MAPE and MAE on Sunday were about 15% points and about 10 points higher than weekday characteristics. Also, on Friday, the forecast error was high on weekdays, similar to Sunday's forecast error, unlike Tuesday, Wednesday, and Thursday, which had weekday characteristics. Therefore, when forecasting the time series belonging to Friday, it should be regarded as a weekly characteristic having characteristics similar to weekend rather than considering as weekday.

Fifteen mongrel dogs (14 male and 1 female) were injected intravenously with 30mg of streptozotocin and 50mg of alloxan monohydrate per kilogram of body weight to induce diabetes mellitus. Before treatment with streptozotocin and alloxan fasting serum glucose concentration was determined every other day or thrice a week (Monday, Wednesday, Friday) for 3 months. Among 15 dogs 4 dogs developed diabetes mellitus and survived more than 9 weeks without injection of insulin. After treatment fasting serum glucose and hemoglobin $A_1$ concentrations of the 4 dogs were determined every other day or thrice a week. Fasting serum glucose concentration increased acutely from 24 hours after treatment and then showed severe fluctuation. Hemoglobin $A_1$ concentration increased gradually until 7~9 weeks after treatment and then showed very slow increase afterwards. Correlation of hemoglobin $A_1$ to fasting glucose concentration was relatively weak(r = 0.10~0.80). Hemoglobin $A_1$ and fasting glucose concentration of preceding 7 week showed very high correlation (r = 0.98~0.99). It was indicated that hemoglobin $A_1$ concentration in chemically induced diabetic dogs reflects mean glucose concentration of preceding 7~9 weeks.

Characteristics of the ozone concentrations in Seoul were analyzed for the data between May and September from 1996 to 2000. Observation data from 27 stations in Seoul are used. Among the results from 27 stations, representative results from 2 stations (City hall and Gwanak representing downtown and background areas of Seoul, respectively) are presented. The 24-hour average ozone concentrations of Gwanak (28.6 ppb) are higher than City hall (14.9 ppb). The 24-hour average ozone concentrations on Sunday are higher than other days at both sites. During weekday, the 24-hour average ozone concentrations on Wednesday are higher than other days. Although the mean of the I-hour daily maximum ozone concentrations at Gwanak is higher than City hall, the . ozone concentrations above 95th percentile at City hall are higher than Gwanak. As a result, the number of days on which the 1 - hour ozone concentration exceeding 100 ppb and 120 ppb at Gwanak (17 and 3) are lower than City hall (29 and 9). To sum up, both sites are VOCs limited region and the mean ozone concentration in Gwanak is higher because of the lower N0$_2$ concentration. But high ozone cases occur more frequently in City hall when conditions are right.

The purpose of the study is to evaluate the differential effects caused by the interviewers and the days of the week using the 24-hour dietary recall method on the dietary evaluation of nutrient intakes. Thirteen subjects were interviewed by three trained interviewers on a Monday, Wednesday, and Friday. The consumption of nutrients by the subjects during each day was assessed. The average intake of nutrients was found to be sufficient except in calcium, iron, and vitamin A. there was a significant difference between the food intake on the weekdays and that o the weekend. However, the were no significant differences between the interviewers assessments on the intake of nutrients consumed by the subjects. The standardization of the portion size, interview skill and experience may be a few of the reasons explaining the elimination of the potential error created by variations among the interviewers. This study suggests that repeated 24-hour recalls during weekdays and weekends may be a better method for estimating the nutrients consumed by the subjects.

Purpose: This study, using a pre-post test design of non-equivalence comparative group, was done to determine effects of Kangaroo care (KC) on growth in premature infants and on maternal attachment (MA). Methods: Fifty-three premature infants were assigned to the KC (24) or control group (CG) (29). Data were collected from July 2007 to June 2008. KC was given for 60 min at a time, Monday, Wednesday, and Friday for 10 times. Weight, height, and head circumference (HC) of premature infants were checked before the program started. Following the initial measurement, the program was given and measurements were taken again at the end of the program. For measurement of attachment between mother and infant, data collection was done using structured self-reported questionnaires. Results: KC group had a higher weight (t=2.565, p=.013), height (t=2.182, p=.034) and HC (t=2.468, p=.017) than the CG. Compared to the CG, the KC had significantly higher scores in MA (t=2.026, p=.048). Conclusion: The results of this study suggest that the practice of KC in the nursing environment might actively promote attachment between mother and infant as well as acceleration of growth for premature infants as one of the most efficient nursing intervention.
