Indoor pollutants seem to have a negative affect on people from vulnerable households who are considered to be weak by the department of environmental health, such as the elderly, infants, children, patients, and pregnant women. In this study, the concentrations of pollutants were measured, especially those pollutants that endanger vulnerable households such as PM10, HCHO, TVOCs, TBC and fungi. The measurements were taken from September to October of 2013 in the Chungnam area. The results were as follows: PM10 33.2 μg/m3, HCHO 20.35 μg/m3, VOCs 132.30 μg/m3, TBC 562.71 CFU/m3 and fungi 362.04 CFU/m3. In the case of TBC and fungi, there were excessive concentrations at 30.9% and 49.3% compared to the standards set by WHO. In the case of fungi, buildings built before the 1980s showed a concentration of 446.23 CFU/m3, those built in the 1980s and 1990s had a concentration of 320.21 CFU/m3 and those built in the 2000s had a concentration of 313.43 CFU/ m3 indicating that fungi concentration was higher when the building was older. The correlation analysis between indoor air pollutants and factors affecting indoor concentrations indicate that HCHO (r = 0.423), TVOCs (r = 0.329), and humidity (r = 0.359) showed a significant difference (p < 0.01). The current study focused on vulnerable households that were unable to protect themselves from indoor pollutants and where poor living circumstances prevailed such as households that do not receive much sunlight; thus, more attention and focus needs to be given to these particular households

Aim of this study is to investigate the nutrition knowledge, dietary behaviors, and dietary habits by the gender in high school students in Chungnam province. Girls students had a higher score than boys students for nutritional knowledge, not in the significant difference. However, boys students had a higher score for dietary behaviors than girls students. Dietary habits showed a significant difference in the unbalanced food habit and eating speed by the gender, and the eating speed of boys students was faster than that of girls students. For boys students, the nutritional knowledge and dietary behaviors did not have the significant correlation. Otherwise, girls students had the positive correlation between the nutritional knowledge and dietary behaviors, and had the characteristics of behaviors that the higher the nutritional knowledge score, the better eating habit. In addition, the boys and girls students had the positive correlation between the score of nutritional knowledge and the frequency of breakfast, and the score of nutritional knowledge and the frequency/regularity of breakfast, respectively. Because some dietary habits/behaviors are related closely to their nutritional knowledge, the high school students need the systematic and steady nutritional education to apply their known nutritional knowledge to actual life.

In terms of awareness of Korean traditional food, elementary students are most affected by their parents. The objective of this study was to analyze upper grade elementary students’ parental awareness and preference of Korean traditional foods in the Chungnam Area. In a survey of 126 parents, 58% of subjects were interested in Korean traditional foods, but there was no significant difference according to age. About 87% of parents thought that inheritance of knowledge on Korean traditional foods was needed. The reasons for inheritance of knowledge on Korean traditional foods were ‘To stick to style of Korean traditional foods’ (68.2%), ‘Palatable’ (21.8%), ‘Education for children’ (6.4%), and ‘Beautiful and fine custom’ (3.6%). The awareness point of ‘Korean traditional foods are easy for cooking’ increased with increasing age (p<0.01). In all age groups, subjects highly recognized that Korean traditional foods are good for health. There were significant correlations between overall preferences for Tteok and Hankwa (r=0.351, p=0.001), Hankwa and Korean traditional drink (r=0.374, p=0.001), and Korean traditional drink and Tteok (r=0.406, p=0.001). As a result, preferences for other items also increased when preference for one of the three traditional foods increased. Therefore, education on Korean traditional foods is necessary in order to satisfy parental preferences.

2011년 6월부터 10월까지 충남 가야산의 현존식생을 대상으로 식물사회학적 군집분석을 수행하였다. 가야산 천연림의 상관우점종은 신갈나무군락과 소나무군락, 소사나무군락, 떡갈나무군락, 굴참나무군락이 전체적으로 우점하고 있었고, 인공식재림의 상관우점종은 잣나무림과 리기다소나무림이 나타났다. 집괴분석에 의한 식생유형은 능선부의 신갈나무군락유형, 남사면의 소나무군락유형, 산복부의 소사나무군락유형, 계곡림유형의 총 4개 유형으로 구분되었으며, 종다양도 지수를 보면 식생단위 4의 종다양도 지수가 0.6976으로 가장 낮았으며, 식생단위 2의 종다양도 지수가 1.1256으로 가장 높게 나타났다. 우점도는 모든 식생단위에서 0.1~0.2인 0.3 이하로, 다수의 종이 우점하고 있는 것으로 나타났다. 또한 4개로 구분된 식생유형 중 계곡림유형은 다른 식생유형보다 출현종이 많은 것으로 나타났으며, 이는 계곡림의 특성으로 판단된다.

The purpose of this study was to estimate the preference, intake frequency and eating behavior for kimchi as well as analyze the differences by gender among fourth to sixth grade students (n=410) in a Chungnam region. Approximately 64% of the students liked the spicy taste of kimchi, 75.9% liked the saltiness, and 48.5% liked well-fermented kimchi. The disliking factors of kimchi were its sour taste (38.5%), strong scent (20.1%), and salty taste (15.4%). The most preferred type of kimchi was Baechukimchi, followed by Kkakduki, Yeolmukimchi, and Chonggakkimchi. Further, the most frequently consumed type of kimchi was Baechukimchi, followed by Kkakduki, Chonggakkimchi and Yeolmukimchi. Oisobaki, welsh onion kimchi, sesame leaf kimchi, Gatkimchi, Nabakkimchi and Baekkimchi were rarely consumed. About 34% of the students consumed 5 to 7 pieces of kimchi per meal, and 84.1% enjoyed eating kimchi, mostly because of its good taste (61.3%). The reason for not eating kimchi was because other side dishes are more delicious (30.2%). About 80% of the students responded that they prepared kimchi at home. Moreover, 74.3% of the students eat kimchi much more at home than at school. Improvements to be made for kimchi at school were as follows: less salty (34.9%), less spicy (27.6%), and sweet (22.5%). In conclusion, students enjoyed eating kimchi because of its good taste. Further, they showed preference for Baechukimchi, Kkakduki, and Yeolmukimchi and consumed them frequently. Because kimchi appears to be more preferred and more frequently consumed, it is necessary to develop a menu using kimchi along with the proper eating guidance for helping students consume various types of kimchi at school or at home.

자유무역협정 등에 의한 세계 농산물 시장의 개방과 지구 온난화 문제로 발생하는 생물상의 변화가 심화되면서 충남지역에서도 돌발해충의 밀도가 급증하고 있으며 주요해충의 발생양상도 변하고 있다. 특히 사과과원에 발생한 갈색날개매미충은 기주범위가 넓고 야산 대부분의 수목에 산란하여 피해를 주기 때문에 농경지 방제에도 불구하고 지속적인 피해를 주고 있으며 2009년 급격히 밀도가 낮아진 꽃매미는 2012년부터 다시 밀도가 증가하는 추세에 있다. 2011년부터 발생한 미국선녀벌레는 충남의 태안, 당진, 예산에서 발생하였으나 현재는 주변으로의 확산이 확인되지는 않고 있다. 소과류인 블루베리의 면적이 확산되면서 국내 미기록종의 과실파리가 발생하였고 시설재배 작물인 토마토에서는 충남전역에서 녹응애의 발생이 확인되었고 오이 시설재배지에서는 초촉성과 촉성재배에서 차먼지응애에 의한 피해가 빈번히 발생하고 있다. 또한 딸기 주산단지인 논산에서는 작은뿌리파리에 의한 유묘기 피해가 확산되고 있다. 백합의 주산단지이니 충남 태안의 경우 연작피해를 줄일 수 있는 상토이용 베드재배가 늘어나면서 작은뿌리파리의 발생이 심각해 졌을 뿐만 아니라 마늘, 맥문동에서는 뿌리응애에 의한 피해가 확산되고 있다. 이들 해충들에 대한 정확한 발생생태와 방제방법에 관한 연구는 시급한 실정이다.

In this study, the concentration distribution of radon, we analyzed from 55 house, 37 government office, 54 schoolfrom June 2008-June 2011 in Chungnam area. From the result of surveying indoor radon degree of 146 facilities,the annual average geometric concentration of indoor radon was 69.4Bq/m³, 40.5Bq/m³, 51.4Bq/m³ in house,government office, school respectively. As for distribution of concentration based on seasons, the radonconcentration showed the highest concentration in winter in all facilities. According to the result of the analysisby dividing the construction year, into before 60s, 60-70s, 80-90s and 2000s, the radon concentration was lowerin all the newly constructed facilities. As for difference in radon concentration due to the presence or absence ofbasement, concentration of house, government office and schools having basement was 52.2Bq/m³, 44.5Bq/m³,36.4Bq/m³ that of having no basement was 75.2Bq/m³, 53.6Bq/m³, 67.4Bq/m³ respectively. Place having nobasement tend to show higher concentration.

본 연구에서는 충남 연안에서 연안조망의 어획 특성을 파악하기 위하여, 2008년 3월부터 2009년 2월까지 매월 2∼4회 연안조망을 사용하여 어획조사를 실시하였다. 조사 해역은 동경 125도 50분∼126도 05분, 북위 36도 15분∼36도 25분의 해역이었고, 총 19목 63과 96종이 채집되었다. 그 중 어류가 54종, 갑각류가 27종, 복족류 및 이매패류가 9종, 그리고 두족류가 6종이었다. 생체량은 어류가 51.4 %로 가장 많았으며, 갑각류는 34.2 %를 차지하였다. 꽃새우는 7월~11월에 출현량이 많았고, 12월부터 5월까지는 적은 양이 출현하였다. 연안조망의 목표종인 꽃새우는 전체 어획물의 2.1 %로 낮은 채집 비율로 출현하였으며, 꽃새우 이외 어종의 부수적 어획물의 양적 비율이 높아, 꽃새우 어획이 부수어획으로 어획되는 종들의 수산자원에 미치는 영향이 클 것으로 판단된다.

자유무역협정 등에 의한 세계 농산물 시장의 개방과 지구 온난화 문제로 발생하 는 생물상의 변화가 심화되면서 충남지역에서도 돌발해충의 밀도가 급증하고 있 으며 주요해충의 발생양상도 변하고 있다. 과수의 돌발해충으로 갈색날개매미충 의 발생량은 급증하여 지난 3년간 발생량을 비교한 결과 발생밀도와 발생면적이 급격히 증가하였다. 꽃매미의 발생은 2009년 이후 밀도가 급격히 낮아졌으나 2013 년부터 다시 증가추세에 있으며 미국선녀벌레의 밀도가 태안군과 예산군 중심으 로 군집되어 있다. 갈색여치의 경우 충북의 영동지역과 인접한 금산군에서 포도와 인삼을 가해하는 것이 확인되었고 금산과 인접한 논산 벌곡에서도 발생이 확인되 었다. 블루베리 재배면적이 급속히 증가하면서 다양한 해충의 발생이 확인되었다. 특히 충남지역의 경우 국내에 존재하지 않는 과실파리 일종이 확인되었으며 심식 나방으로 추정되는 나방류의 발생도 확인되었다. 이들 해충들에 대한 정확한 동정 과 발생에 대한 보고 그리고 화학약제의 등록 또한 시급한 실정이다.

계획대상지는 충청남도 예산군 고덕면 대천리, 석곡리 일원으로 농업환경과 상업가로지역, 역사문화자원 등이 복합적으로 형성되어 있는 지역이다. 하지만 열악한 교통여건과 부족한 대표이미지로 인해 외부방문객들에게는 통과지역으로만인식되고 내부적으로는 면소재지임에도 불구하고 정비되지 않은 가로 환경과 지역주민들의 다양한 커뮤니티를 지원할수 있는 공공시설의 부재로 인해 갈수록 쇠퇴하고 있는 대표적인 농촌지역이라 할 수 있다. 최근 당진영덕고속도로개통과 고덕IC의 개설, 내포신도시로 충청남도청 이전 등 인근지역의 여건 변화로 인해 그동안 쇠퇴되었던 지역을다시 활성화시킬 수 있는 계기가 마련되었고 따라서 본 계획에서는 주변 여건 변화에 발맞춰 지역 환경을 개선하고대상지가 보유하고 있는 지역자원을 활용하여 통과지역으로서 인식되던 이미지를 개선함으로써 발전적인 지역 활성화 방안을 제시하는데 목적이 있다. 이에 본 계획에서는 ‘경관정비’, ‘지역자원활성화’, ‘정주기반정비’를 계획전략으로 수립하여쾌적한 정주환경 및 도농복합 거점공간으로 조성하고자 계획내용을 수립하였다. 본 계획을 통해 그동안 낙후되고 노후화된지역의 공공시설 및 경관자원의 개선과 고유한 지역자원의 활용을 통해서 고덕면소재지 지역주민의 삶의 질이 향상되고지역경제가 활성화 될 것으로 기대된다.

This study summarized findings from an investigation into the awareness and evaluation of traditional foods among 197 male and female university students in the Chungnam area. The results were as follows. Regarding awareness of cooktable setting of traditional foods, 44.67% (88 students) of subjects answered that they had little knowledge. Female students showed a significantly high level of awareness of cooktable setting (p<0.05). Regarding the taste of traditional foods, 64.97% (128 students) of subjects responded appropriately. Regarding the necessity for partial development of traditional foods into a modern style, 61.90% (52 students) of male subjects and 84.96% (96 students) of female subjects were in agreement (p<0.01). Regarding the necessity for traditional food education, 77.16% (152 students) were in agreement, especially female students (86.73%, 98 students) showed considerably higher consent (p<0.05). For the assessment of traditional foods, nutrition (4.57 scores), taste (4.31 scores), and appearance (4.26 scores) were very highly assessed, whereas cookery (3.30 scores) and economic aspects (3.04 scores) scored relatively lower. Traditional desserts were recognized as routine and modern by male students. On the other hand, girls recognized desserts as traditional (p<0.05). Accordingly, we must preserve and pass down Korean traditional foods by increasing awareness through education or experience as well as through planning better cookery and economical aspects by applying certain standards for traditional foods.

The purpose of this study was to investigate the effect of food behavior on dietary food intake status and health condition based on research of food behavior and nutritional intake status of university students in the Chungnam area. The average age, height, and weight of the subject group were 22.1 years old, 174.2 ㎝, and 67.0 ㎏ for the male students and 20.9 years old, 161.8 ㎝, and 53.4 ㎏ for the female students, respectively. From the nutritional intake status data, the averaged daily energy intake of both groups, male and female, are lower than the dietary reference intake(KDRI), as 2, 169.2 kcal and 1, 846.2 kcal, males and females, respectively. The lipid intake ratio was higher than the dietary reference figure, and the carbohydrate intake ratio was determined to be in the proper range. Male students(54.6%) and female students(52.0%) of the entire subject group skipped a breakfast mainly due to insufficient time, and the time at which meals were consumed, was determined to be irregular generally. In a day, male and female students have a heavier dinner than lunch(p<0.05), respectively. Meat and fishes are preferred by the entire subject group, and the number of students, who do not eat carrot and mayonnaise(p<0.05), was determined to be the highest, of all foods surveyed. The averaged daily activity coefficient and the resting energy expenditure shows significant difference(p<0.001) between two groups; was 1.7 and 1.6 and the second was 1, 404.3 kcal/day and 1, 292.5 kcal/day for the male and female groups, respectively. As the number of attempting to reduce body weight(p<0.001), the amount smoking(p<0.001), or the frequency of drinking alcohol increases, BMI decreases. On the other hand, as body shape satisfaction increases, BMI increases also.

The purpose of this study was to provide basic information regarding desirable body image recognition by examining body image recognition 395 middle school students in the Chungnam area. The average age of the subjects was 13.7 years for boys and 12.6 for girls. Their average height and weight were 165.4 ㎝ and 57.1 ㎏ for boys, and 155.7 ㎝ and 48.8 ㎏ for girls. As for body shape, girls thought that they were overweight more often and wanted to lose weight compared to the boys. Over half of the respondents answered that their weight control efforts were not systematic such ad via professional counseling. Weight control by students was attempted by themselves in order to control their weight by skipping meals. Further, the subjects exhibit dietary behavioral problems such as overeating, skipping meals, unbalanced diet, and eating speed. In conclusion, correct body image recognition is needed and families and schools should make efforts to help students properly control their weight and adopt proper eating habits.

This study was performed to investigate the consumption of coffee beverages and energy contribution ratios of coffee beverages and accompanying snacks by college students in Deajeon City and Chungnam Province in Korea. Questionnaire survey, dietary survey, and snack survey using food record method during 3-days were carried out. As a result, we found that 86.9% of male students and 75.6% of female students consumed coffee beverages usually, with no differences between the two groups. However, the frequency of coffee beverages consumed by female students out-numbered that of male students by 1 cup a day to 1-2 cups a week (p<0.05). Furthermore, male students most likely consumed coffee beverages at schools or academies, but female students consumed them at coffee shops (p<0.01). The reasons male students gave to consume coffee beverages were for scent, taste, fatigue, and to stay awake. Similarly, the reasons female students gave to consume coffee beverages were for scent, taste, habit, and to stay awake (p<0.01). Fully 58.1% of male students and 80.0% of female students ate snacks along with coffee beverages (p<0.01). Most male students substituted a coffee beverage and accompanying snack for a regular meal once a month. Female students were doing it at most 2-3 times a month (p<0.05). The mean daily dietary energy intake of male students was 1,924 kcal/d, and of female students was 1,518 kcal/d (p<0.001), which both were below the estimated energy requirements. Male students obtained 285.6 kcal/d and female students obtained 289.5 kcal/d from coffee beverages and accompanying snacks. There was a significant different in dietary intake of energy (p<0.05), calcium, and iron (p<0.001) for each ratio of reference intake between male and female students. The students who ate larger amounts of coffee beverages and accompanying snacks consumed less dietary energy, protein, calcium, and iron, respectively (p<0.05). These results show that many students consume coffee beverages regularly and obtain large amounts of energy from coffee beverages and accompanying snacks. It also shows that student's dietary nutrient intake tends to be poorer, as he or she obtains more energy from coffee beverages and accompanying snacks. Therefore, it is critical to monitor the influence of consumption of coffee beverages and accompanying snacks on the dietary nutrient intakes and health of college students, and to provide nutrition education about the proper consumption of coffee beverages and accompanying snacks based on scientific evidence.

본 조사는 유구천의 수생식물과 수변계류식물의 목록을 작성하고 관속식물의 다양성을 연구하기 위해 문헌조사를 포함하여, 2009년 8월부터 2010년 9월까지 총 4회에 걸쳐 7개 지점을 조사하였다. 7개 지점의 조사를 통해 유구천의 관속식물은 88과 229속 290종 3아종 30변종 5품종 328분류군으로 확인되었다. 조사지역 내의 한국 특산식물은 개나리(Forsythia koreana (Rehder) Nakai), 오동나무 (Paulownia coreana Uyeki), 병꽃나무 (Weigela subsessilis (Nakai) L.H. Bailey) 등 3분류군이 확인되었다. 산림청 지정 희귀 및 멸종위기 식물은 낙지다리 (Penthorum chinense Pursh), 땅나리 (Lilium callosum Siebold & Zucc.), 꽃창포(Iris ensata var. spontanea (Makino) Nakai), 창포 (Acorus calamus L) 등 4분류군이 확인되었다. 식물구계학적 특정종은 총 27분류군이 확인되었는데, 그 중 중요한 의미를 가지는 III~V등급종은 V등급종이 2분류군, IV등급종이 2분류군, III등급종이 9분류군으로 총 13분류군이 발견되었다. 귀화식물은 10개과 27분류군이 확인되었으며, 이는 조사된 전체 목록 중 약 8.3%를 차지하는 것으로 확인되었다. 유구천은 마을이 하천을 따라 발달하고, 도로나 농경지 등에 따라 인간의 간섭이 지속적으로 증가 할 것으로 여겨지며 이에 따라 귀화식물의 유입도 증가 할 것으로 판단되어진다. 조사지점별 식물들의 집괴분석과 좌표 결정분석 결과 유구천 본류형, 소하천형, 저수지형 등 3개 모둠으로 구별되었다.

The purpose of this study was to investigate the dietary habits and snack consumption behaviors of middle school students with different obesity indexes in the Chungnam area. The survey was carried out using self-questionnaires and included 385 students(119 underweight, 193 normal weight, 66 overweight). The rate of skipping meals was higher for underweight students than overweight students; however, this difference was not statistically significant. The mean time of meal was 10 to 20 minutes and the criteria for choosing to eat a meal were ‘hunger’ and ‘taste’ in all groups. More than half of the subjects ate snacks 1 time a day, which were purchased outside. The typical snack time was ‘between lunch and dinner’. The criteria of for consuming a meal were ‘taste’ and ‘price’ in all groups. In the underweight group, the snack food scores were ice cream(4.4), fruit(4.3), fried chicken(4.1), sports beverage(4.0), fruit juice(4.0), pizza(4.0) and, tteokbokki(3.9). In the normal weight group, the snack food scores were ice cream(4.3), fried chicken(4.2), pizza(4.0), sports beverage(3.9), fruit juice(3.9) and, tteokbokki(3.9) in the overweight group, the snack food scores were ice cream(4.3), fruit(4.3), fried chicken(4.2), yogurt(4.0), sports beverage(4.0), fruit juice(4.0) and, ramen(4.0). In conclusion, the snaking behaviors of the subjects were not significantly different based on their obesity index. However, this study may provide basic information on the snacking behaviors of middle school students, and the findings suggest that nutrition education or counseling can improve snack intake habits and positive behaviors toward healthy adolescents diets.

이 연구는 충청남도 태안군에 생육중인 활엽수종들의 초식에 대한 방어전략을 탐색하고자 67종의 활엽수를 대상으로 방어전략을 결정하는 잎의 형태적 특성, domatia구조, 초식곤충 및 포식응애의 서식여부를 조사하였다. 조사 대상 67종 중에서 46종(68.7%)의 활엽수가 domatia 구조를 채택하고 있는 것으로 나타났다(Table 1). 참가시나무와 태산목 등을 비롯한 21종의 활엽수에서는 domatia 구조가 없었으며, 황매화와 서어나무를 비롯한 31종의 활엽수에서는 엽액 사이에 털이 밀생하여 공간을 만드는 tuft type domatia를 지녔고, 난티잎개암나무와 떡갈나무를 비롯한 12종의 활엽수에서는 pocket 모양구조에 털이 나있는 pocket+tuft type domatia를 지녔고, 왕벚나무와 팥배나무에서는 pocket type domatia를 지녔으며, 아왜나무에서는 pouch type domatia를 지녔음이 확인되었다. 잎 뒷면의 털을 이용한 방어전략으로 태산목에서의 밀융모, 은백양과 포도에서의 밀면모, 보리수나무에서 비늘털 밀생, 칡의 강모 밀생 등이 밝혀졌다. 화외밀선(花外蜜腺; extrafloral nectary, EFN)을 이용한 방어전략은 조사대상 중에서 23종(34.3%)의 활엽수가 이를 채택하고 있는 것으로 나타났다. 대표적인 사례로 앵두나무, 무화과, 가막살나무 및 서어나무 등이었다. 조사 대상 중에서 40종(59.7%)의 활엽수에서 포식응애의 서식이 확인되었으며, 잎에 서식하는 응애 개체수 평균은 떡갈나무에서 23.4마리로 가장 많았다. 잎을 가해하는 미소 절지동물류는 진사진딧물, 단풍알락진딧물, 깍지벌레, 혹응애, 총채벌레등이었으며, 총 개체수는 혹응애, 깍지벌레, 진딧물, 총채벌레 순이었다. 이들의 천적으로는 포식응애, 말벌, 무당벌레류와 그 애벌레, 진딧벌 등이 확인되었다. 이 연구의 결과로 온대 활엽수종에서 상리공생을 포함한 여러 가지 방어전략이 활용되는 경우가 흔함을 확인할 수 있었다.
