The purpose of this study was to compare and analyze dietary self-efficacy and Nutrition Quotient (NQ) according to the degree of food-related content use in university students. From October to November 2022, a total of 332 college students (140 males and 192 females) attending universities in Chungcheongbuk-do were surveyed to collect data on general information, food-related content use level, dietary self-efficacy, and NQ for adults. The average dietary self-efficacy score of the group that did not use food content was 3.08 points, which was significantly higher than the group that watched it sometimes (2.89 points) and the group that watched it often (2.83 points) (p=0.0191). The total NQ score of 48.85 points was the highest among the three groups (p=0.0270). For subjects who responded that they had no experience of eating food at all after using food content, their dietary self-efficacy was 3.03, which was significantly higher than the group with occasional or frequent food consumption experience (p=0.0194). Results of this study can be used as basic data for clarifying the relationship between the use of food-related content and eating habits in university students and for proper eating habits education for university students.

The occurrence of eggs and adults of Pochazia shantungensis, Lycorma delicatula, and Lymantria dispar was investigated in 11 cities in the Chungcheongbukdo region. The results showed that the overwintering eggs of P. shantungensis occurred in 24.2% of the region in 2021 and 22.1% in 2022, while adults occurred in 25.2% in 2021 and 24.3% in 2022, indicating the highest occurrence among the pests studied. The occurrence of overwintering eggs of L. delicatula was relatively low, with 2.6% of the region affected in 2021 and 1.9% in 2022. Adult L. delicatula occurred in 3.2% of the region in 2021 and 3.6% in 2022. Overwintering eggs of L. dispar occurred in 4.1% of the area in 2021 and 1.7% in 2022, showing a decreasing tendency compared to the previous year, and their occurrence was only low to middle in terms of the degree of occurrence. Adult L. dispar occurred in 4.6% of the region in 2021 and 2.7% in 2022, showing occurrences that were insignificant compared to L. delicatula. According to a survey of host preferences, both the wintering eggs and adults of P. shantungensis were found in apples and peaches between 2021 and 2022. In both 2021-2022, adult L. delicatula had a high incidence in peaches, apples, and grapes, and winter eggs were the highest in grapes. However, the incidence in apples and peaches was low. A high incidence density of L. dispar moth adults and overwintering eggs was found in apples in both 2021 and 2022.

본 연구는 2016년부터 2020년까지 충북 보은지역의 참진드기류의 시기별 분포를 조사하였다. 참진드기류는 다양한 환경(매년 4지점)에서 채집하였고, 5년 동안 충북 보은지역에서 채집된 참진드기류는 2속 3종으로 작은소피참진드기(Haemaphysalis longicornis), 개피참진드기(Haemaphysalis flava), 일본참진드기(Ixodes nipponensis)로 총 17,704개체의 참진드기가 채집되었다. 작은소피참진드기는 가장 많은 28.83 T.I. (68.40%) 값을 보였고, 개피참진드기 1.49 T.I. (3.53%), 일본참진드기 0.02 T.I. (0.06%)순으로 채집되었고 종 동정이 되지 않는 유충은 11.81 T.I. (28.01%)로 조사되었다. 우점을 차지하는 작은소피참진드기는 봄철 (5-6월)에, 유충은 8월과 9월에 가장 많은 수가 채집되었다. 대부분의 채집지에서 작은소피참진드기가 가장 많이 채집되었고 무덤과 초지에서만 유충이 많이 채집되었다. 개피참진드기는 충북 보은지역에서 채집된 개체수는 적지만 모든 채집지에서 분포하는 것으로 나타났다. 5년간 채집된 3종의 참진드기류에 대하여 총 828 pools의 SFTS 감염률을 조사한 결과 모두 음성으로 병원체 감염이 확인되지 않았다.

This study aimed to investigate the use of environmentally friendly agricultural products (EFAPs) in Chungcheongbuk-do and the perception and satisfaction of school dietitians with EFAPs. The study survey was conducted from April to Jun 2018. Among 195 dietitians, 54.4% were nutrition teachers and 51.3% were working in elementary schools. Of the participants, 65% answered that the percentage of EFAPS in the total food cost was 10~30%. The most used EFAP food group was grains (64.6%), followed by vegetables (26.2%). The main reasons for using EFAPs were subsidies for EFAPs from local governments (85.1%) and students’ health (52.3%). The average daily subsidy for EFAPs from the local governments was 201~500 won at 45.1%, and 200 won or less at 34.9%, which was based on one meal per student. In questions on satisfaction with using EFAPs, satisfaction with safety (3.93 out of 5 points) scored the highest, followed by nutrition (3.74), freshness (3.70), appearance (3.32), diversity (2.85), and price (2.78). Therefore, to expand the use of EFAPs in school food service, it is necessary to expand the provision of subsidies and increase EFAP production diversification.

대표적인 연성변형구조인 습곡에서 습곡축의 자세는 3차원 습곡구조의 발달양상뿐만 아니라 변형 당시의 최대 수평주응력 방향에 대한 정보를 수집하는데 중요한 역할을 한다. 이러한 이유로 습곡축의 자세를 파악하는 것은 매우 중요하나 습곡축이 노출되는 경우가 흔하지 않기 때문에 습곡과 관련된 구조요소들을 이용한 다양한 방법들이 제시되고 이용되어 왔다. 따라서 이러한 다양한 측정방법에 대해 간략히 소개하고, 이들 방법들에 대한 신뢰성을 평가하기 위하여 같은 습곡에 대해 다른 측정법을 사용하여 측정한 습곡축들을 비교분석 하였다. 이를 위해 습곡구조가 잘 발달해 있는 충북 단양지역 조선누층군의 석회암층들과 평안누층군의 만항층에 걸쳐 6곳의 노두에서 습곡구조의 습곡축 자세를 측정하고 비교하였다. 비교결과 다른 방법에 의해 측정된 것들도 대부분 서로 잘 일치하는 양상을 보여 다양한 측정방법들의 실제 활용이 가능함을 보여주었다. 또한 단양지역의 습곡구조는 서북서 방향의 습곡축을 가지는 한 곳을 제외한 나머지 노두에서 모두 북-북북동 내지 북동 방향의 습곡축을 보였으며, 이는 서북서-동남동 내지 북서-남동 방향 의 최대수평주응력 환경에서 만들어진 습곡들로 판단된다. 서북서 방향의 습곡축은 다른 시기의 습곡작용을 지시하는 것으로 보이며, 북-북북동 방향의 습곡축을 가지는 습곡구조와 북동 방향의 습곡축을 가지는 습곡구조 사이의 주향 차이는 하나의 습곡작용에서 습곡구조의 규모에 따라 다소 차이가 생긴 것으로 해석하였으나, 증거를 확인하는 추가적인 연구가 필요할 것으로 사료된다.

This study aimed to investigate the relationship between eating speed and nutritional status among Korean high-school students using Nutrition Quotient for Korean Adolescents (NQ-A). In this study, a questionnaire survey was conducted in 453 high-school students (227 boys and 226 girls) from September 2019 to October 2019 in Chungbuk area. Based on the self-reported speed of eating data, subjects were classified into a fast group (n=180), a medium group (n=184), and a slow group (n=89). NQ-A scores for each group were measured in each speed group. In the environment section, girls showed a significant difference in usage time of electronic devices, such as TVs and smartphones: the fast group spent significantly more time than the medium group (p=0.035). In the practice section, among boys, the slow group had significantly higher scores for washing hands before eating than the medium and the fast groups (p=0.022). This study suggested that eating speed of high school students is associated with health-related environment factor and practice factor of NQ-A, such as time spent on smart devices or washing hands before eating. The study results can provide baseline data for nutrition education on health management of high school students.

화상병균(Erwinia amylovora)에 의해 발생하는 과수 화상병은 주로 사과, 배 등의 장미과 식물에서 발병한다. 과수 화상병은 국내에서 금지 병원균으로 지정되어 있으며, 2015년 경기도 안성의 배과수원에서 최초 발견되었다. 그러나, 현재까지 근본적인 방제약제가 없는 상황으로 발생지는 매몰이 최선의 방법으로 여겨진다. 따라서 본 연구에서는 2019년을 기준으로 충북지역의 과수 화상병 발생 원인 분석을 통하여 발생 경로 차단을 위한 역학조사를 실시하였다. 1. 충주시 등 3개 시군의 전체 221농가 141ha에서 과수 화상병이 발생하였으며, 세부적인 연도별 발생현황은 2015년(2농가 1ha), 2018년(74농가 51.5ha), 2019년(145농가 88.9ha) 로 나타났다. 2. 과수 화상병의 발생시기는 주로 5월부터 8월 사이로 나타났으며, 특히 6월(73.8%)이 가장 많이 발생하였으며, 7월 (17.2%), 5월(7.6%), 8월(1.4%)순으로 나타났다. 3. 과수 화상병 발생 의심 신고 후 확진 매몰까지 소요기간은 11.9일이었고, 발생에서 매몰까지의 기간은 최단 5일에서 최장 19일로 조사되었다. 4. 병원균의 최초 발생지로부터의 확산 거리는 평균 21 km로 나타났으며 가장 먼거리는 음성군 비산면으로 34 km였다.

This study investigated the current status of foodservice management and the importance and performance of foodservice management according to the level of knowledge of workers. A survey was conducted between February 2015 and March 2015 for 329 foodservice workers at Community Child Centers in Chungbuk Area. Of these respondents, the majority (78.4%) of them were females. Most of them were in their 40s (40.4%) or 50s (33.4%). If the respondent's correct answer rate of knowledge was 0~50% or 51~100%, the respondent was classified into a ‘Low Group (LG, n=175)’ or a ‘High Group (HG, n=154)’. Among a total of 14 foodservice management questions, 6 items (personal hygiene: 1 item; food material: 2 items; and food processing: 3 items) had relatively higher performance scores for workers in HG than for workers in LG. As a result of Importance-Performance analysis, ‘Use different knives and cutting boards for fish, meat, and vegetables’ was a variable of high importance but low performance. It was found that improvement was most urgently needed. Results of this study can be used to derive important items for improving foodservice management and policy development for foodservice workers at Community Child Centers.

In this study, a survey was conducted among university students (119 men and 134 women) in Chungbuk province using questionnaires to investigate the variables and eating patterns related to the use of food delivery apps. A survey was conducted from March 22, 2019 to April 3, 2019. Of the total respondents, 77.2% reported that they had ordered food at least once using food delivery apps on smartphones. Further, 63.3% of the total subjects had ordered food delivery through smartphone apps once or twice a month, and the most preferred cuisine for food delivery was fast food, followed by Bunsik (Korean street food/snack), western food, and Chinese food. The average satisfaction scorefor food delivery apps was 3.8 points, and the satisfaction score was the highest with the convenient ordering process (4.0), followed by good taste (3.9) and good portion (3.8). The subjects who used smartphone food delivery apps three times or more a month showed a significantly higher frequency of instant food intake (p=0.0132), dining out (p=0.0282), and late-night eating (p=0.0047) than the subjects who ordered food using delivery apps less than three times a month. In conclusion, these study results may be applied as baseline data for dietary education among university students.

The purpose of this study was to investigate the quality characteristics of Doenjang made by seven different traditional soybean paste manufacturers, in Chungbuk province during fermentation. The moisture content of Doenjang declined in the process of fermentation, from 58.07~68.86% to 52.32~63.79%. The salinity increased from 7.47~14.38% to 10.42~17.73%. Sample B was the lowest, and G was the highest. The pH showed a tendency to decline from 5.36~6.22 to 4.30~5.66 except for sample F, which increased 6.33~7.10. In contrast, the total acidity showed a tendency to increase from 0.56~1.77% to 1.11-1.83% except for sample F, which declined 0.71%~0.54%. The lightness declined from 44.33~55.90 to 26.68~49.66. However, the redness and the yellowness generally increased. The content of amino type nitrogen generally increased with the progress of fermentation from 93.33~408.80 mg/kg to 314.07~1,258.13 mg/kg and sample D, with Aspergillus oryzae added, was the highest. The volatile flavor compounds of Doenjang had 10~20 types. Sample D had the fewest number of volatile flavor compounds (10 types of compounds), and sample C had the largest number of it (20 types of compounds). Four types of compounds, ethanol, 3-methyl butanal, ethyl acetate, and 3-methyl butanoic acid, were detected from all samples.

The purpose of this study was to investigate the factors related to milk consumption in university students. A questionnaire, comprised of general questions and factors related to milk consumption, was administered to 269 male and female university students (134 males, 135 females). The results show that the proportion of males reporting that they drink milk because “for good nutrition” was higher than that of females (p=0.0200). Additionally, males initiated more effort to drink milk than females (p=0.0192). Analysis of the groups classified according to milk consumption shows that the proportion of respondents exercising regularly was significantly high in the milk consumption group (p=0.0199). The proportion of respondents often consuming carbonated drinks as snacks was significantly low in the milk consumption group (p=0.0219). Whereas, the proportion of respondents consuming fruits as their main snack was significantly higher in the milk consumption group than in the non-milk consumption group (p=0.0063). Also, the milk consumption group shows significantly higher awareness of the importance of milk than the non-milk consumption group (p<0.0001). These results can be used as a valid foundation to provide university students with nutritional education relative to milk consumption and its associated benefits in the future.

충북의 한지형 마늘 재배지에서 파총채벌레와 파좀나방의 발생양상과 약제검정을 수행하였다. 파총채벌레 발생양상은 3월 중순에 발생하기 시작하여 5월 중하순경 부터 밀도가 급격히 증가하였다. 파좀나방은 3월 중하순에 발생이 시작되어 수확기인 6월 중순까지 2화기 발생하였다. 9종의 살충제를 이용하여 파총채벌레와 파좀나방의 약제감수성을 조사하였다. 실내 검정 결과 파총채벌레에 대하여 clothianidin SC, chlorfenapyr EC, dimethoate EC, imidacloprid WP, cyantraniliprole + thiamethoxam WG가 100%의 살충효과를 보였다. 파좀나방에 대해서는 cyantraniliprole EC, pyridalyl EW, spinetoram SG, abamectin + chlorantraniliprole SC가 100%의 살충효과를 보였다. 2종 해충에 대하여 실내검정에서 살충효과가 높았던 약제 각각 5, 4종을 대상으로 포장검정을 수행한 결과 모든 약제에서 처리 3일차에서 90% 이상의 방제효과를 나타내었다.

최근 대추에 장님노린재에 의한 피해가 발생함에 따라 대추재배 농가들이 적절한 방제를 할 수 있도록 시기별 발생 밀도, 우점종 조사, 방제 가능 약제 선발 등의 시험을 수행하였다. 대추과원에서 발생하는 장님노린재의 발생 밀도를 2년에 걸쳐 조사한 결과, 약충은 5월 상순부터 발생 하여 7월 중순까지 발생 하였으며, 성충은 5월 하순부터 발생하여 7월 중하순까지 발생하였다. 또한 대추과원에서 발생하는 애무늬고리장님노린재와 초록장님노린재의 밀도의 경우 45개체 중 40개체가(약 89%) 애무늬고리장님노린재 인 것으로 조사되어 대추나무를 가해하는 장님노린재 중 우점종은 애무늬고리장님노린재 인 것으로 나타났다. 대추과원에서 장님노린재 방제에 활용할 수 있는 살충제에 관한 정보를 제공하기 위해 9 종 살충제들을 대상으로 한 야외시험에서 pyrifluquinazon, deltamethrin, diazinon, dinotefuran, etofenprox, fenitrothion, bifenthrin 7종 이 80% 이상 살충력을 나타냈다. 따라서 본 시험에서 조사된 살충제를 이용하여 대추나무 발아 직전부터 방제를 하면 대추과원에서 장님노린재 방제가 가능 할 것으로 판단된다.

콩 재배지에서 콩씨스트선충(Heterodera glycines)과 반짝이씨스트선충(Heterodera sojae)의 지리적 분포에 관한 조사를 강원도와 충청북도 지역에서 수행하였다. 강원지역 10개시군, 67개 포장에서는 콩씨스트선충이 13개소, 반짝이콩씨스트선충이 5개소에서 검출되었고, 두 선충 혼 재하는 포장도 2곳이었다. 충북지역 9개 시군에서는 84개 조사 포장 중 27개소에서 콩씨스트선충이 검출되었고, 반짝이콩씨스트선충 4개소, 두 선충 혼재 발생지 5곳이었다. 강원, 충북 지역에서 콩씨스트선충류 검출 여부에 따라 발생하는 다른 식물기생성선충 속의 다양성과 우점도 지수 는 콩 재배지 사이에 유의한 차이를 나타내지 않았다. 콩씨스트선충과 토양 화학성 사이의 관계 분석에서는 결정계수가 낮게 나타났으며 콩씨스 트선충의 밀도가 높은 토양에서는 pH와 가용성 인산 함량이 높은 것으로 나타났다. 씨스트선충이 검출된 토양의 토성은 사질토가 전체 샘플의 60%를 차지하였다. 점토와 미사의 함량이 높은 토양에서는 콩씨스트선충의 밀도가 낮은 경향을 보였고, 모래 함량이 높은 토양에서 밀도는 높게 나타났다.
