A receptor model application was performed by using a chemical mass balance (CMB) model to identify and apportion the specific source of airborne organic pollutants, particularly polynuclear aromatic hydrocarbons (PAHs). Source profiles of PAHs produced from the combustion of fossil fuels for CMB modeling were prepared by measuring them in emission gases. The emission sources which were examineed for the development of PAH source profiles are a coal-fired furnace using Yontan, a bunker-C iol heating boiler, and gasoline-and diesel engine automobiles. The ambient concentrations of PAHs were determined at four sites in Daejon city in 1991 with a seasonal variation. Wintertime air samples contained more extractable organic matter than summertime samples. The results of CMB modeling were various depending on the sampling sites and seasons, but the emission from bunker-C oil heating boliers was the predominant factor to affect local air quality throughout the year.

Purposes of the study were to find out the joint effects of two salient appearance cues-hair colors and hair lengths on males fashion images, using 729 university students in Daejon city and a Chungnam province. The study was a quasi experiment; the dependent variables were hair lengths(4 levels) and hair colors(4 levels)and the dependent variable was a set of semantic different of scales which was consisted of 40 hi-polar adjectives, The data were analyzed by a factor analysis, 3-way ANOVA, and the results were as follows. Hair lengths effected on the image of five dimensions, salient, social, potency, evaluate and dynamics while hair colors effected on salients, social and potency dimensions. The most significant interaction effect between hair color and lengths were existed on the salient image: For the longer haired males, the color effects became less evident then normal to shorten haired males and it can be concluded that when two salient cues were combined one cue's effect became discounted.

Twenty four metal, nonmetal elements and 4 major anions in total suspended particulates (TSP) collected at two sites in Daejon city from october to december in 1991 by a Hi-vol sampler were thoroughly analyzed by Inductively Coupled Plasma/ Atomic Emission Spectrometry (ICP/AES) and Ion Chromatography (IC). These analyzed data were used to perform a receptor modeling using the Chemical Mass Balance (CMB) for the source apportionment of TSP sample. Approximately 60% TSP weight in industrial complex area was influenced by potential industrial sources and 25% was by heating fuels and automobile emissions, whereas a half of TSP in residential area was influenced by surrounding environment and more than 35% of TSP was influenced by heating fuels. The CMB model provided source apportionment results reasonably and scientifically with a minor limitation.

In order to investigate the complaint rates of subjective fatigue symptoms and the degree of job-satisfaction among dental hygienists based on their socio-demographic and job characteristics and to find out the factors related with subjective fatigue symptoms and job satisfaction. The study subjects were recruited from 274 dental hygienists who worked at dental hospitals and clinics in Daejon city and South Chungcheong Province during the period between Jan. 5 and Feb. 11, 2008. They were asked to complete the self-administered questionnaires asking about their socio-demographic characteristics. job characteristics. daily life styles, job satisfaction and subjective fatigue symptoms, and the major finding of the results were as follows : 1. The mean scores of job satisfaction were 3.12V0.47 of the total full scores(5.00). and the highest scores were in the sub-domain of interpersonal relationship. and the lowest scores were pay. The scores of job satisfaction by socio-demographic characteristics and daily life styles were not significantly differences, but in job characteristics, significantly increased with those feeling satisfied with their job. those with appropriate amount of duty amount, those free of jop autonomy, those feeling satisfied with their monthly income. satisfactory personal relations at work. 2. The mean scores of subjective fatigue symptoms were 27.6V10.9 of the total full scores(60.0), and the highest scores were in the sub-group of bodily projection of fatigue(Group III), and they were followed by difficulty in concentration(Group II). dullness and sleepness(Group I) in their decreasing order of magnitude. The scores of job satisfaction by socio-demographic characteristics and daily life styles were significantly increased with the group of lower age, the group of irregularly breakfast habit and the worse subjective health status. Based on job characteristics. the score of subjective fatigue symptoms were significantly increased with those group of lower clinical career and monthly income, those feeling unsatisfied with their job, those with inappropriate amount of duty amount. those satisfactory personal relations at work 3. The correlation of subjective fatigue symptoms with job satisfaction showed a negative correlation with rM-0.198(pM0.000), and job satisfaction were higher according to the lower subjective fatigue symptoms. The correlation among the scores of sub-domain of job satisfaction and the sub-group of subjective fatigue symptoms were significantly positive correlation. 4. The affecting factors of significance on job satisfaction included clinical career, duty amount salary satisfaction, with the explanatory power of 32.9%. Those on subjective fatigue symptoms included the eucation and the subjective health statuts, with the explanatory power of 20.8%. When considering these results, the job-satisfaction and the subjective fatigue symptoms were significantly correlated with the job related factors than factors of socio-demographic characteristics and daily life styles.

Purpose: This study purposed to supply basic data for nursing intervention plan for middle-aged women healthcare and for finding solutions to nursing problems through understanding middle-aged women's depression, and to examine whether middle-aged women's depression is related with self-concept, self-efficacy, physical condition and social support. Method: The subjects were 200 middle-aged women aged between 35 and 60 and living in Daejon city and K city in Chungcheongnam-do, and the questionnaire survey was conducted from the 15th of August to the 18th of September in 2003 using a structured questionnaire. Collected data were analyzed through descriptive statistics, t-test, ANOVA. Pearson's correlation coefficient and stepwise multiple regression. Result: Middle- aged women's depression was found to be in a negative correlation at a statistically significant level with self-concept (r=-.679, p=0.000), self-efficacy(r=-.489, p= 0.000), physical condition(r=-.650, p=0.000) and social support(r=-.526, p=0.000). The most significant variables of middle-aged women's depression was self-concept(46.2%). Combining with physical condition(13.2%) and self-efficacy(0.9%), the three variables together explained 60.3% of middle-aged women's depression. Conclusion: The results show that middle-aged women's depression is closely related with self-concept, self-efficacy and physical condition. Thus this study suggests that the goal of nursing intervention for middle-aged women to overcome depression should be to help them to have positive self-concept, high self-efficacy and sound physical condition.

The purpose of this study was to evaluate the urban park and the green spaces within the public service framework. It was investigated by identifying the priority elements as defined by the residents and to figure out the differences of residents' satisfaction for the parks in new and old downtown. This study surveyed 455 residents from 80 dong (neighborhoods) of 5 Gu(districts) in Daejon. In this study, satisfaction on the urban parks and the green spaces in the old downtown was compared with the new town area. The results were as follows: Those who lived in the new downtown areas showed higher satisfaction than those in the old downtown for the urban parks and the green spaces, as well as in all 8 other evaluation sections. Both new and old downtown residents scored high on the 'city landscape and the natural environment' and 'green spaces and facilitats' items, but scored low on 'citizen's respect' and 'acceptance of resident opinions'. The old downtown residents highly valued on easy access to the parks, while the new downtown residents focused on various activities and programs, as well as resident participation, as the parks. The variables affected the resident's satisfaction on the urban parks in old downtown areas consisted of 'information', 'diversity', 'supply decision'. Among these variables, 'diversity' had the most significant influence on the satisfaction level.

The purpose of this study was to investigate consumer preferred formats of nutrition labels: the type of nutritional information provided on the labels. A survey was conducted on 222 housewives between the age of 20 and 65 in Daejeon city in 1998, using an interview questionnaire showing illustrated nutritional label formats. Among twelve nutrients and caloric values listed on the nutrition labels, the housewives ranked their interest in the items in the following order of calorie (58.56%), calcium (56.76%), cholesterol (54.05%), protein (39.19%) and vitamin C (36.04%). The majority of the subjects (69.37%) checked labels when they bought milk or dairy products, whereas only 8.11% looked at labels when they bought Ramyon or noodles. Most of the subjects (90.99%) preferred products with labels with nutritional information as compared with products without labels. this was especially so true of the younger individuals and of pc-ople who checked food labels more frequently. The subjects preferred labeling which described the nutrient content per Package (55.41%), sewing size (32.88%) and food weight of 1009 (11.71%) as a standard nit. Generally, they prefer-red a simplified list to a detailed list of the number of nutrients, a figure graph to bar graph in nutrition claim, vertical bar graph to horizontal bar graph showing the nutritional content of foods and a web-type graphic format to a radiation-format when describing the item's percentage of the Korean RDA's nutrient content. The subjects who checked labels frequently especially preferred detailed list, while housewives with job or with unhealthy family members preferred a simplified list and graphic, rather than a numerical display. From this result, it is suggested that providing consumers with more nutrients information in a more easily understood graphic format would encourage the consumers to check nutritional labels. Therefore this should be considered when developing the regulations far nutrition labeling or when educating the Public about nutrition. (Korean J Community Nutrition 8(2) : 220∼230, 2003)

King of Jujeong(周定王) named Jusuk(朱橚) was thought to be an exemplary character as a scholar and a politician, who was not an Oriental medical doctor but a compiler publishing a set of three medical books and a set of volumes on famine relief to save people in the areas of natural disasters or spring poverty. He was born on July 1, 1361 as the fifth son of Juwonjang(朱元璋), the first Emperor (1368-1398) of the Myeong-dynasty (1368-1644) of China. It was not clearly known about his mother other than assuming, but hard to ascertain, that she was from Goryeo, the ancient country in the Korean Peninsula, and became a loyal concubine of Juwonjang(朱元璋). He was the brother of Yeongrakje(永樂帝), the third Emperor(1402-1424) of the Myeong-dynasty. As a focal figure in the political forces at that time in the Myeong-dynasty, he had a life full of vicissitudes such as being removed from office, being exiled to a remote place, being scattered far and wide between family members, being implicated in the rebellion and so on. It seemed that he brushed up on his study, taking a class on an emir until the year of 1380 at the age of twenty. And he published "Bosaeng-yeorok(保生餘錄)" and "Bojebang(普濟方)" for eight years from 1381 to 1389 (at age 21-29), "Sujinbang(袖珍方)" in 1391 (at 31), and "Guhwangboncho(救荒本草)" in 1406 (at 46), republishing "Sujinbang(袖珍方)" in 1415 (at 65). Endowed with a brilliant talent from early days, Yeong-rakje(永樂帝) wrote the poem(the poem paying a high tribute to a King) well and composed one hundred pieces of poetry on the story of the Won Dynasty (1271-1368) of China. He leaded a quiet life in his later years and died a natural death at Gaebong(開封, a city in China) at 65 in 1425. He had 15 sons including king of Juheon(朱憲王) Yudon(有敦) and 11 daughters. His books contributed absolutely to the growth of Oriental medical field, and also to the increase in population, having influence on bringing about compilation of the books on Oriental medicine and famine relief of the Joseon Dynasty (the old Korean kingdom from AD 1392 to 1910).
