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.

This study looked over the laws and regulations related to forestry workers to analyze the safety accident rates for the past five years (2006-2010), and to suggest improvement plans to reduce the safety accident rates of forestry workers. Findings from comparing information obtained from data are outlined below. The safety accident rates had gradually increased in the forestry fields until 2010, but nowaday it is on the decline. Furthermore, the safety accident rates in the field of forestry were still serious compared to those in the other industrial fields as from 2.1 to 5.1 times. In the results, the workers were especially vulnerable to safety accidents when they fell under the following categories: when falling; within 29 to 90 days after starting the work; over 60 years old; less than one month of service; October; Wednesday; 11 a.m.; and the nether limbs of the body. In the case of Jeollabuk-do, it was reported that more than half of victims did not have any training in safety.

This study aimed to analyze how a variety of relations created by the actions of characters shown in SBS Wednesday and Thursday dramas are communicated by using Greimas' actantial model. This study analyzed the sparsity structure that the subject have in relations between the subject, and a desire structure that the subject have will appear if we look into the interactive and binding relation between the subject and the object in the process of solving those problems. In the relations between the subject and originator, the role of originator in the dramas was limited when his or her character is established as a poor character weaker than the subject and the one to be protected, whereas he or she was more authoritative than the subject in the structure that originator shares a role as an antagonist. Objectors shown in three works gave help to the solution of incident after all by turning coat as another cooperators of the subject and the object, showing a tendency to reach maturity rather than being unhappy.

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.
