This study examined the quality characteristics of 10 different lines of native peppers collected from organic farms in Chungbuk province. The study found a strong correlation between the redness (a*) and ASTA values, which both contribute to the perceived quality of peppers. The highest values were observed in the Iyugsa line. The content of capsaicinoid and beta-carotene also showed a positive correlation, with Chilsungcho having the highest statistically significant value. While the total polyphenol content did not correlate with the other indicators, Chilsungcho again had the highest levels. The Yuwolcho line exhibited the highest ABTS radical scavenging ability, while the Eumseongcho line showed the highest DPPH radical scavenging ability. Taking into account the overall bioactivity quality, Chilsungcho had the highest values in terms of total polyphenol, beta-carotene, capsaicinoid, and redness. It also had the second highest total flavonoid content, ABTS, and DPPH radical scavenging activity, all statistically significant. Therefore, Chilsungcho can be considered an excellent choice when considering physiological activity. Furthermore, this study provides valuable information about the unique characteristics of these 10 native pepper lines, which can assist in selecting the appropriate pepper for food manufacturing and serve as a helpful resource for future research.
This study aims to explored changes in vocabulary use in Jeongamchon, which was founded by immigrants from Chungcheongbuk-do, Korea, in China. The data were collected from the first generation of Chungcheongbuk-do and Jeongamchon immigrants as well as the second generation of Jeongamchon immigrants. The data were divided into eight categories. The Jeongamchon community preserved a considerable number of dialects from Chungcheongbuk-do but also showed the transition of words into Chinese Korean. Examples of Chungcheongbuk-do dialect words that are highly conserved in Jeongamchon include words frequently used in daily life such as words about the human body and titles for relatives and family members. In contrast, words from Chungcheongbuk-do dialects indicating entities that do not exist in Jeongamchon, which can be attributed to differences in geographical environments or sociocultural differences between Chungcheongbuk-do and Jeongamchon, were at the verge of extinction. The indigenous vocabulary items in Jeongamchon, which refer to objects reflecting sociocultural differences from Chungcheongbuk-do, were substituted into the Chinese-Korean dialect, reflecting local culture.
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.

1950년 교육법 개정에 따라 ‘고등학교’가 다수 신설된 지 벌써 72년이 지났다. 그럼에도 고등학교 명칭에 관한 심도 있는 연구는 아직까지 수행된 바가 없었다. 그래서 충북 중학교에 이어 충북 고등학교 명칭 특성을 분석하였다. 2022.04.01. 기준 82개 고등학교 명칭에 관한 분석 결과는 다음과 같다. 학교명의 어종은 한자어가 90.2%로 압도적이었고, 평균 음절수는 3.7음절로 중학교 명칭보다 길었다. 생성 유형은 결합지명이 50.6%로 가장 많았고, 행정지명이 30.1%, 인문지명이 19.5%였다. 행정구역 관련 학교명은 80.5%였는데, 시・군・구 관련 학교명(50.0%)이 가장 많았으며, 중학교보다 상위 행정구역과 관련된 명칭의 비중이 높았다. 개명 사례는 총 82건으로 중학교에 비해 훨씬 빈번하고 복잡하였다. 폐지 사례는 13건이었는데, 대부분 읍・면부 소재 일반계 공립 고교들이었다.
지방선거는 정치대표성의 확보와 지방의 정책결정 기관의 유능성 확보와 지방 정치엘리트 충원, 교육 및 훈련 측면에서 중요하다. 지방 정치엘리트는 지방선거로 충원되며, 이들의 역량은 지방의 정책결정 및 정치대표성 및 전문 성 등을 가늠할 수 있는 척도다. 따라서 지방 정치엘리트의 인구통계학적 현황을 반영한 정치대표성은 지방 정치의 정치 지형에 영향을 미치는 중요한 요소이다. 이러한 관점에서 이 논문은 민선 7~8기 충북의 지방선거에서 광역· 기초의회의 선거 결과를 빈도 분석하여, 정당별·성별·연령·학력 및 직업 등 인구통계학적 현황과 특성을 분석하였다. 정당별 특성에서, 거대 양당의 의석 독점 또는 양분 현상으로 중앙정치에 의한 지방 정치 현안과 의제의 부재를 고착화하였다. 성별·연령별 특성에서, 비례대표제도를 통해 여성의 지방의회 진출이 미약하게 이루어지고 있으나 지역구 선거에서 여전히 여성의 정치대 표성은 낮았다. 또한 연령별 특성에서 ‘30대’ 당선자가 기초 의회에 진입하게 되어, 지방 정치의 새로운 변화를 가져올 것으로 기대된다. 학력별·직업별 특성에서는 고학력 인구의 증가로 지방 정치엘리트 역시 고학력이 다수였고, 정당과 정치인 중심으로 과대 대표되고 있다.
Swine atrophic rhinitis is a respiratory disease that causes nasal turbinate loss and septal deformation due to Bordetella bronchiseptica and Pasteurella multocida. Turbinate loss facilitates pathogens to infect lungs, which leads to various respiratory diseases and productivity reduction. In this study, descriptive analysis was implemented for atrophic rhinitis and pneumonia. From 6 pig farms shipped to slaughterhouses in Chungbuk province, 20 heads and 20 lungs were collected by each farm from March 2020 to September 2020. Their atrophic rhinitis lesions and lung lesions were scored and blood samples were also collected to test the seroprevalence of several respiratory diseases. Pasteurella multocida from nasal swab was cultured and antibiotic resistance tests were performed. Correlation between atrophic rhinitis scores and lung lesion scores was not found. Abdominal nasal lesions were more severe than dorsal lesions. Differences in lung lesion scores were relatively small between lobes. The score of pneumonia was higher in castrated pigs than in female pigs. There was no relationship between lesion score and seroprevalence of respiratory diseases. Antibiotic resistance levels for Pasteurella multocida differed by farm, and several antibiotics were not effective. The results of this study imply that antimicrobial susceptibility tests are highly recommended before administration.
This study investigated on the nutritional components and physiological activity of four wild vegetables namely Salvia plebeia R. Br., Angelica acutiloba, Gynura procumbens and Saururus chinensis Baill for the development of representative wild vegetables in Chungbuk. Salvia plebeia possessed the highest radical scavenging activity and beta-carotene, but exhibited the lowest α-glucosidase inhibitory activity compared to the other three vegetables. Angelica acutiloba showed high crude protein content and α-glucosidase inhibitory activity, but contained low total polyphenol content, radical scavenging ability and beta-carotene compared to the other three vegetables. Gynura procumbens showed high mineral content, beta-carotene, vitamin K1 content and α-glucosidase inhibitory activity, but showed the lowest total polyphenol content and radical scavenging ability compared to the other three vegetables. Saururus chinensis showed high crude fiber content and total polyphenol content, but contained the lowest mineral and vitamin K1 content. To conclude, it is suggested to use Salvia plebeia or Saururus chinensis as antioxidant food materials and Angelica acutiloba and Gynura procumbens as food materials and sources of α-glucosidase inhibitors. In particular, it is believed that Saururus chinensis, which possessed high content of crude fiber, is suitable for low-calorie food materials such as diet products.
110년의 충북 중등교육의 역사에도 불구하고, 충북 교육에 관한 체계적인 연구는 매우 미흡하다. 그래서 충북 중학교의 특성에 대한 분석을 시작하였다. 2021. 04. 01. 기준 128개 중학교의 명칭에 대한 분석 결과는 다음과 같다. 학교명의 어종은 한자어가 98.4%로 압도적이었고, 평균 음절수는 2.63음절로 상당히 짧았다. 명명 유연성은 행정구역명 관련 학교명이 67.2%로 가장 많았고, 인문지명이 18.0%로 다음을 차지하였다. 면명에서 연유한 다수의 중학교가 폐지되면서 행정지명의 비중이 상당히 감소하였다. 1970년 25.6%를 차지하였던 사립중학교는 현재 14.8%로 감소하였다. 1981년 20.6%를 차지하였던 여자중학교는 현재 13.3%로 감소하였다. 1952년 이후 개명 사례는 15건이 있었는데, 사립중학교와 여자중학교의 비중이 상대적으로 높았다. 1952년 이후 실제 폐지된 중학교는 19개교인데, 대부분 농촌 지역의 공립중학교였다.
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.
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 봄철 기온이 높아짐에 따라 마늘 뿌리응애 피해가 늘어나고 있는 실정이다. 이러한 뿌리응애 피해를 최소하 하고자 발생양상과 22종의 약제에 대하여 살비효과를 조사하였다. 마늘 재배시기 중 뿌리응애의 발생은 충북 보은 등 5지역에서 2015년부터 2017년까지 3년간 3월부터 6월까지 뿌리응애 발생밀도를 조사하여 발생양상을 확인하였다. 뿌리응애는 2016년에 가장 많이 발생하였으며, 발생시기는 월동 후 3월 상순부터 발생하여 6월 중순경까지 지속적으로 밀도가 높아지는 양상을 나타내었다. 조사된 5지역 중 가장 높은 밀도로 조사된 보은지역은 6월 상순경 주당 13.3마리가 발생하였다. 뿌리응애에 대하여 우수한 살비효과를 나타낸 약제는 분무처리시 약제처리 10일 후에서 dimethoate, azocyclotin, abamectin, hexythiazox, cabosulfan, spirotetramat, benfuracarb가 90% 이상의 살비효과를 나타내었다
The distribution of mosquitoes collected in Cheongju area in 2016 and 2017 were compared. The collection sites wereestablished from residential area, migratory bird sanctuary, and cattle feedlot using BL trap and BG trap. Culex pipienswere the most collected in residential area, and Aedes vexans were the most collected in migratory bird sanctuary andcattle feedlot in both years. BG trap was more collected than BL trap in residential area and migratory bird sanctuary.However, cattle feedlot was more collected in BL trap. A variety of mosquito species were collected from BG trap thanBL trap. However, the number of Anopheles sinensis collected in cattle feedlot showed significant differences betweenBL trap and BG trap. Based on the results of this study, it is considered that effective monitoring of mosquitoes mightbe done by using appropriate trap type according to the region
As increased the cultivating areas of several minor crops for medicine such as Glycyrrhiza uralensis, Astragalus membranaceus, Taraxacum platycarpum, Gynanchum wilfordii, and Purple granadilla, the occurrence of major pests and their damages were severed. Primarily occurred pests on five minor crops were observed small in size pests such as whiteflies, aphids and thrips, but the other pests are insignificantly infest. Whiteflies showed higher density in G. uralensis but its damage was insignificant level. Aphids were showed higher density at June in all minor crops and then sharply decreased the density with lower degree of damage. The high damage on initial growth stage will be judge to affect on the yield. Thrips on T. platycarpum showed higher density with 44.1%, compare to other crops, sharply increased the density in late-June and optimal peak in mid-July and decreased in late-Aug. Conclusively, major pests on crops, green peach aphid, mites species on A. membranaceus and G. uralensis, olender aphid, mites species and thrips on G. wilfordii were damaged. Detailed investigation and analysis for economic value of the damaged pest for the continual production will be promoted and then followed the procedure the registration of agrochemicals.

 ,  , Seasonal fluctuations of Riptortus pedestris were investigated in four regions including two sites each at Mt. Yangseong (Munui-myeon, Cheongwon-gun), O-chang (Cheongwon-gun), and Jujung-dong (Cheongju) using aggression pheromone traps from April to November in 2010 and 2011. Aggression pheromone and aggression pheromone + soybean traps were set at all investigated sites, and the Mt. Yangseong A and B sites were investigated at a farmland (80 m, asl) and forest (200 and 300 m). The population density of R. pedestris was high in mid June, mid August, and late October in 2010 and in early May, mid June, mid September, and early October in 2011 with trivoltine. O-chang and Jujung-dong populations, which were distinguished in farmlands and forests, were highest from June to August in the farmland and in September in the forest. Similar numbers of R. pedestris were capture in the farmlands and the forest in June–August, September–November, respectively. From the results of the four regions, more R. pedestris adults were captured in the aggression pheromone + soybean trap than that in the pheromone trap. To investigate the migration route by altitude, 500 R. pedestris adults marked with fluorescent paint were released and re-caught insects were counted in traps after 10 and 20 days. The pattern of the re-caught R. pedestris indicated migration from the forest to farmlands during April–June. These results suggest that the insects did not migrate in August because food was plentiful in the forest at 200 m, but they moved to the forest during October due to the scarcity of food and for overwintering. The R. pedestris seasonal fluctuations in 2011 were affected heavily by the environment, particularly rain precipitation.
This study was investigated the seasonal occurrence of Metcalfe pruinosa (Say) in Chungbuk province and established the optimal control timing. Population densities of nymph and adults were investigated and egg hatching period and oviposition period was examined from three locations (Cheongwon, Jincheon, Eumseong area). Egg hatching period was investigated. The first day of egg hatching observed on May 25, the day of peak egg hatching was on May 29, and the perfect accumulative egg hatching ratio was on Jun. 13. Oviposition period of M. pruinosa female was observed the cut branch (cut within 10 cm length, 1 cm dia.) of oak tree, an althea, and an acacia under stereoscope. The first oviposition was observed at Jul. 28 and continually increased until late-Sept. with sharply increased at mid-Aug. Population density of M. pruinosa nymph was observed the cut branch (cut within 30 cm length, 1 cm dia.) of oak tree, an althea, an acacia, and pear tree. Population density began decreased showing after highest density with 25.3 (Jul. 1). The adult was first appeared at Jul. 11 and showed highest population density with 13.1 (Aug. 4) and then continuously decreased.
To control M. pruinosa at pear orchard, optimal control timing for nymph was judged from Jun. 13 to Jul. 2, because of its small size of body and exuviae, low damaging by honeydew producing, low wax materials produced. Second control timing was judged at early Aug., when the adult invading to the pear orchard from near forest and the period before oviposition. The control agents for M. pruinosa were not yet registered, but will be anticipated to register the chemicals such as penitrothion WP, acetamiprid WP, dinotefuran WP, lambda cyhalothrin, thiamethoxam SP in 2012.
