대전의 3대 하천인 갑천, 유등천, 대전천에 대하여 2002년 4월부터 2004년 3월까지와 2006년 1월부터 12월까지 3년간 조류분포에 대한 조사를 수행하였다. 조사결과 관찰된 조류는 총 13목 34과 126종 12,027개체(최대합계수)로 나타났다. 우점종은 흰뺨검둥오리, 쇠오리, 집비둘기, 참새, 쇠백로 등의 순서였다. 관찰된 조류는 크게 6개 분류군이었으며, 가장 많은 종이 관찰된 분류군은 교목성 산림조류로 54종이었고, 가장 적은 종이 관찰된 분류군은 잠수성 오리류로 7종이었다. 또한 개체수는 관목성 산림조류가 721개체로 가장 적었으며, 수면성 오리류가 4,974개체로 가장 많았다. 각 하천별 조류분포를 보면 갑천은 총 13목 34과 114종 14,885개체(최대합계수), 유등천은 총 12목 30과 90종 6,642개체(최대합계수), 대전천은 총 11목 28과 69종 4,202개체(최대합계수)가 관찰되었다. 각 하천별로 조사된 종수, 개체수, 종다양도, 종풍부도, 단위면적당 밀도 등의 조류군집분석 지수에 의한 하천별 유사성을 분석한 결과, 갑천과 유등천 그리고 유등천과 대전천은 서로 유사한 특성을 가지는 하천이며, 갑천과 대전천은 서로 다른 특성을 갖는 하천으로 구분되었다. 또한 각 하천 구간별 상위 10위 우점종을 대상으로 유사성을 분석한 결과 각 하천의 상류는 산림성조류, 중류는 해오라기류와 수면성 오리류, 하류는 수면성 오리류와 일부 잠수성 오리류가 서식하였다. 이러한 결과는 대전 3대 하천에서 일부 구간이 자연형 하천으로 남아있는 갑천과 유등천이 도심지역인 대전천에 비하여 다양한 조류가 서식한다는 것을 의미하며, 각 하천의 상류와 하류가 조류의 서식에 적합하다는 것을 의미하므로 향 후 도시하천의 정비나 활용에 있어 자연성이 유지되는 구간에 대한 보전 및 관리가 필요하였다.

We surveyed 821 children (ages 12-15 y) in Daejeon city and Cunngcheong province, Korea for their use of vitamin·mineral supplements (VMS), either over-the-counter drugs and/or health functional foods (HFF). We also considered the significant variables of VMS use, including demographic characteristics, health-related variables, eating habits and nutritional beliefs of VMS by subjects. The frequency of VMS use was 24.8% and, in comparison to counterparts, it was higher in subjects attending middle school (p<0.001), in those living in a large city (p<0.001), in those with a high monthly family income (p<0.05), and in those with high concerns about school performance by parents (p<0.01). Selfhealth concerns by subjects (p<0.05) and concerns about health of offspring by parents (p<0.01) were higher in users than in nonusers. Eating habits of subjects did not affect the use of VMS. Users had a more positive view concerning the potential health benefits of VMS than did nonusers (p<0.05). Most users took VMS when they were healthy (78.9%) and expected ‘disease prevention and health maintenance’ (44.6%). However, most users did not feel any special effects from VMS use (58.8%), and they got their information on VMS through family and relatives (53.9%). Users of VMS preferred vitamin C supplements (44.2%) and Ca-supplements (56.9%). Therefore, the results show that VMS use is widely spread among the subjects, and that use of VMS is influenced by multiple variables and subjective criteria. Therefore, practical guidelines on VMS use for children’s health and growth should be given through nutritional education.

목적: 대전지역 대학신입생들의 굴절상태와 안광학상수를 측정하여 성인의 굴절이상 변화에 미치는 요인들을 분석하였다. 방법: 2008년 3월과 2009년 3월 2회에 걸쳐 76명(남 23명, 여 53명)을 대상으로 기본신체검사, 자동굴절검사, 각막곡률반경, 전방깊이, 안축장을 현성 및 조절마비 상태에서 측정하였다. 결과: 등가구면 굴절이상도는 -0.080±0.301D(p=0.001) 근시방향으로 진행하였고, 각막곡률반경은 -0.015±0.040 mm(p=0.000) 감소하였다. 전방깊이는 0.036±0.066 mm(p=0.000) 증가하였으며 안축장의 변화는 유의하지 않았고(p=0.274), AL/CR 비는 0.004±0.020(p=0.004) 증가하였다. 각막곡률반경 변화량과 굴절이상도 변화량은 양의 상관성이 있었고(r=0.578, p=0.000) 굴절이상도 변화량과 AL/CR 비의 변화는 음의 상관성이 있었다(r=-0.542, p=0.000). 굴절이상도 변화량과 안축장 변화량의 상관성은 유의하지 않았다(r=-0.074, p=0.367). 굴절이상도에 따른 변화에서 근시군의 등가구면 굴절이상도가 -0.134±0.316D 증가하여 원시나 정시보다 변화량이 가장 컸다. 근시군에서 굴절이상도 변화와 각막곡률반경 변화는 양의 상관성을(r=0.664, p=0.000), AL/CR 비 변화와는 음의 상관성을 보였다(r=-0.600, p=0.000). 각막곡률반경 변화와 AL/CR 비 변화는 음의 상관성을 보였다(r=-0.719, p=0.000). 정시군에서 굴절이상도 변화와 안광학성분 변화의 상관성은 유의하지 않았다. 원시군에서 굴절이상도 변화와 각막곡률반경 변화만 양의 상관성을 보였다(r=0.490, p=0.024). 결론: 이상으로부터 성인근시도의 증가는 각막곡률반경 변화 및 AL/CR비의 변화와 관련이 있으며, 성인근시의 원인은 안구성장보다 각막곡률반경의 변화가 더 큰 영향을 미치는 요소로 추정된다.

To determine the relationships between soybean food intake, dietary isoflavone intake, and osteoporosis incidence, questionnaire surveys, bone mineral density measurements, and dietary surveys by food record were performed with 19 postmenopausal women (57.6±7.3 yrs of age) in Daejeon city. The subjects were divided into two groups: an ‘osteoporosis group’ (OG, n=10) and a ‘normal group’ (NG, n=9). Mean age, height, and body weight were similar between the two groups but BMI was higher in OG than in NG. Mean age at menarche was not different between the two groups. However, mean number of childbirths was greater in OG than in NG and mean total period of lactation was shorter in OG. Mean exercise time per week was similar between the two groups, and mean time of sunlight exposure tended to be shorter in OG. Mean daily intake of calcium was lower in OG whereas sodium intake was higher in OG. Mean daily intakes of total soybean food (OG: 203.8±84.6 g/d, NG: 285.0±146.3 g/d) and total dietary isoflavone (OG: 29.1±14.3 mg/d, NG: 38.3±23.1 mg/ d) were not different between the two groups. However, greater intakes of soybean food and dietary isoflavone were associated with higher bone mineral density, respectively. The above results indicate that osteoporosis incidence tends to be influenced by BMI, maternal factors, dietary nutrient intakes, soybean food intakes, and dietary isoflavone intakes in postmenopausal women; although no significant differences in soybean food and dietary isoflavone intake were found between the two groups. This tendency implies that greater intakes of soybean food and dietary isoflavone lead to lower incidence of osteoporosis in postmenopausal women.

Antistatic acrylic resin is made from n-butyl methacrylate, methyl methacrylate, dimethyl amino ethyl methacrylate(DMAEMA), 2-ethyl hexyl methacrylate, hydroxy ethyl methacrylate, 2,2'-azobis iso-butyronitrile by synthesis. To achieve a lowest surface resistance of antistatic acrylic resin was applied to a variety of synthesis processes. The acrylic resin has been determined from the value of surface resistance and -then the antistatic acrylic resin including dimethyl amino ethyl methacrylate of the 10%, 20% and 30% is synthesized. Finally, dimethyl sulfate(DMS) on a variety of weight ratios is added to antistatic acrylic resin. When DMAEMA / DMS weight ratio is 1/1, antistatic acrylic resin isn't haze the lower the surface resistance. Compared to the traditional antistatic agent, all aspects of the physical properties is outstanding.

This study was conducted to investigate the perception and understanding parents had regarding environment friendly agricultural products being used for school foodservice. A trained practitioner surveyed 221 parents of children at elementary schools in Daejeon using a questionnaire, after which the resulting data were analyzed by a Chi-square test. Overall, the parent's responses regarding the foodservice were positive. However, most of the parents do not participate (65%) in the school foodservice if they work, and those that do participate primarily work as meal service aides (58.1%). Parents indicated that the work of urgent field of inspection on food materials (69.9%), and the reason of an agreement (98.2%) for them were the students' health (68.4%). In addition, most parents were positive about the possibility of replacing foods used in the school with environment friendly products (51.6%) and felt that the government should pay the additional expense associated with their replacement. Furthermore, the majority of the parent's surveyed felt that children should be supplied with vegetables (54.9%) purchased directly from farms. The parents' satisfaction with the meal service (25.1%) was lower than that of the students (54.1%). The reason for the satisfaction reported by the parents was concern regarding the health of their children (53.3%). In addition, the majority of the parents (47.3%) responded that environment friendly agricultural products differ from general agricultural products because insecticides and fertilizer were not used. The main objection parents had to using environment friendly products was their cost (59.1%), and most parents felt that a realistic solution to this problem was unified purchase (41.4%). Besides, a problem when replacing with them was the expensive price (38.1%) and true or false (37.7%), and the students' satisfaction (59.5%) was selected the most in an effect of using them, diversity of the product (39.1%) and price reduction (32.6%) for a solution of the increase of using them.

In this study, VOCs originating from vehicles were measured at 8 underground parking lots(two apartments, four department stores, and two large-scale marts) in Daejeon. The indoor air quality at underground parking lots of the department stores and marts was affected by the availability of the ventilation facility and their operation frequency. At the underground parking lots with a ventilation facility, the maximum VOCs concentration was 727㎍/㎥, and the minimum was 73.5㎍/㎥. The average concentration ratio of BTEX to TVOCs at the underground parking lots was almost constant, which was approximately 44.8%. TVOCs and BTEX were strongly correlated with a correlation coefficient (r) of 0.88. The relative ratio of benzene, toluene, ethylbenzene and xylene was 1 : 9.51 : 0.71 : 2.53, directly reflecting the influence of vehicles sources.

This study aimed to offer some basic data for nutrition education to housewives by comparing behaviors of eating out targeted on housewives who live in Daejon surveyed by classification of regions and by family forms. As for their ages, 79 housewives (16.0%) are less than 30, 179 housewives (36.8%) are between 30 and 39, 156 housewives (35.9%) are between 40 and 49 and 74 housewives (15.2%) are more than 50, and as for their final academic careers, 204 housewives (41.9%) graduated from universities, which was the most and as for religions, 172 housewives (35.3%) had no religion, which was the most, and in the case that they had religions, 137 housewives (27.5%) believed in Christianity. And as for occupations, 327 housewives (69.0%) had no job, and in case they had jobs, 123 housewives (25.3%) that occupied the most were professional. As for husbands’ occupations, profession was the most for 143 housewives (29.4%) and as for monthly income, 2 million won~3 million won was most as 40.0%. As for times of eating out, ‘4 times a year’ was said by 131 housewives (26.9%), which was the most, and as for the times of food home service, ‘seldom’ was said by 221 housewives (45.4%), and as to the expense for eating out a month, ‘less than 100,000 won’ was said by 219 housewives (45.0%), which was the most, and as for the reasons of their eating out, ‘for harmony in a family’ was said by 119 housewives (24.4%). As for times of eating out by general items of housewives, it was appeared that the younger, the higher in education, less in religion, more in occupation, the more professional in their husbands’ jobs, the more nuclear in family forms, fewer in number of family members and the more average family income per a month, they had more times of eating out. Regarding the factors influencing on eating out, ‘high price’, ‘nutritive imbalance’ and ‘use of MSG’ were pointed by 204 housewives (41.9%), 83 housewives (17.0%) and 63 housewives (12.9%) respectively as the problems of food service shops. And as for the question why their went to their regular restaurants, 185 housewives (38.0%) said ‘taste of food’, and the most considerable thing when they selected menu at a restaurant was ‘taste of food’ for 167 housewives (34.3%). The survey showed that a lot of housewives thought the prices at restaurants were high, and they valued taste of food most, therefore food service shops should improve the taste and nutrition of food.
