이유노,김현경,김길하 한국응용곤충학회 2024 한국응용곤충학회지 Vol.63 No.3

청주와 증평에서 채집한 섬서구메뚜기(Atractomorpha lata)의 발생과 온도(20°C, 25°C, 30°C)에 따른 령기별 발육기간, 성충수명, 산란수 및 부화율 등을 조사하였다. 섬서구메뚜기는 5월 말부터 부화약충이 나타나기 시작하여 7월말부터 성충이 출현하고 8월 중순에 성충의 밀도가 가장 높았다. 청주와 증평에서 채집된 모든 령기에 대한 야외개체의 암수 비율은 각각 0.49와 0.45로 유사하게 조사되었다. 섬서구메뚜기 암컷은 6령까 지의 약충기를 거쳐 성충이 되지만 수컷은 5령 약충기만으로 성충이 되었다. 령기별 약충의 발육기간은 온도가 높아질수록 짧았으며 암컷이 수컷보 다 모든 온도에서 더 길었다. 성충의 수명은 온도가 높아질수록 암수 모두 감소하였고 암컷과 수컷 모두 20°C에서 각각 158.9일과 127.3일로 가장 긴 기간 동안 생존하였다. 온도가 높아질수록 산란전기는 짧아졌으나, 산란수는 반대로 증가하였다. 그러나 난괴당 산란수는 온도별 큰 차이를 보이 지 않았다. 섬서구메뚜기의 알은 30°C이상에서만 부화하여 52.0% 부화율을 보였다. 본 연구결과는 섬서구메뚜기를 방제하기 위하여 발생과 발육 에 관한 기초자료로써 활용가능 할 것으로 생각된다. This study investigated the occurrence of Atractomorpha lata in Cheongju and Jeungpyeong and assessed the developmental period, adult longevity, number of eggs, and hatching rate at each developmental stage under different temperature conditions (20°C, 25°C, and 30°C). The first nymphs of A. lata began to appear in late May, adults appeared in late July, and the density of adults was the highest in mid-August. The sex ratios of A. lata at all developmental stages sampled from Cheongju and Jeungpyeong were similar at 0.49 and 0.45, respectively. Females and males exhibited differences as they reached adulthood after the 6th and 5th instar nymph stages, respectively. The developmental period of nymphs at each instar became shorter with increase in temperature; notably, females had a longer period than males at all temperatures. The longevity of adults decreased as the temperature increased, and both males and females survived the longest at 20°C, at 127.3 d and 158.9 d, respectively. As the temperature increased, the pre-oviposition period decreased but the number of eggs laid increased. However, the number of eggs in the egg masses did not differ significantly under different temperature conditions. Eggs of the A. lata hatched only at temperatures above 30°C, showing a hatching rate of 52.0%. The findings of this study provide baseline data for controlling A. lata.

이유대,노영재 한국지구과학회 1991 韓國地球科學會誌 Vol.12 No.4

This paper reports on the investigation of the distributions of sediments and heavy metals in Sooyoung River and its mouth, carried out during the period from July 1990 and August 1991. Since the samples were saline, water analysis was performed by the method of alkaline KMnO₄ and sediment analysis by acidic KMnO₄. Mercury was digested with both nitric and sulfuric acids, and then determined by dithizone CCl4 method. Cadmium, Zinc, Copper, Lead and Chronium were determined by atomic absorption spectroscopy after aliquots of samples were digested with nitric acid and hydrogen peroxide. Mineral components of sediments were identified by XRD and microscopic analysis. The result are as follows : 1. The ranges of COD of water and sediments were 10.6-54.6ppm and 63-26000ppm respectively. 2. The ranges of concentrations of Cadmium, Lead, Copper and Zinc for water were 0.002 -0.024ppm, 0. 013-0.060ppm, 0.013-0.736ppm, 0.003-0.012ppm, respectively. 3. The ranges of concentration of Mercury, Cadmium, Lead, Copper, Zinc and Chromium for sediments were N.D - 0.09ppm, 0 .1-2.07ppm, 0.32-5 2.35 ppm, 1.04 - 20.67 ppm, 7.1-52.50 ppm and 0.23-5.22 ppm, respectively. 4. The mineral components of the sediments were mainly quartz and feldspar.

COVID-19 팬데믹 영향으로 대면 소통이 어려워지면서 비대면 소통의 영향을 파악하는 연구가 진행되고 있으나 메신저 애플리케이션 리뷰를 통해 이를 살펴본 연구는 미비하다. 본 연구는 구글 플레이 스토어 내의 메신저 애플리케이션 리뷰 데이터를 수집하여 LDA(Latent Dirichlet Allocation)토픽 모델링을 통해 팬데믹의 영향을 파악하고, 이에 따른 서비스 전략 방안을 제시하고자 한다. 연구에서는 팬데믹이 시작된 시점과 사용자가 부여한 평점을 기준으로 데이터를 분류하였다. 분석 결과 주로 중장년층이 메신저를 사용하는 것으로 나타났으며, 팬데믹 이후에는 가족과의 소통이 증가한 것으로 확인되었다. 사용자들은 애플리케이션의 업데이트에 대해 불만을 표현하였으며, 변화에 대한 적응이 어려움을 보였다. 이에 업데이트 주기를 조정하고 사용자들의 의견을 적극 수용하는 개발 접근이 필요하다. 또한, 직관적이고 간편한 사용자 인터페이스(UI)를 제공한다면 사용자 만족도를 향상시킬 수 있을 것으로 기대된다. As face-to-face communication has become difficult due to the COVID-19 pandemic, studies have been conducted to understand the impact of non-face-to-face communication, but there is a lack of research that examines this through messenger application reviews. This study aims to identify the impact of the pandemic through Latent Dirichlet Allocation (LDA) topic modeling by collecting review data of 메신저 applications in the Google Play Store and suggest service strategies accordingly. The study categorized the data based on when the pandemic started and the ratings given by users. The analysis showed that messenger is mainly used by middle-aged and older people, and that family communication increased after the pandemic. Users expressed frustration with the application's updates and found it difficult to adapt to the changes. This calls for a development approach that adjusts the frequency of updates and actively listens to user feedback. Also, providing an intuitive and simple user interface (UI) is expected to improve user satisfaction.

The development of information and communication technology and the improvement of the development and dissemination of smart devices have caused changes in the form of tourism, and the concept of smart tourism has since emerged. In this regard, researches related to smart tourism has been conducted in various fields such as policy implementation and surveys, but there is a lack of research on application reviews. This study collects Trip Advisor application review data in the Google Play Store to identify usage of the application and user satisfaction through Latent Dirichlet Allocation (LDA) topic modeling. The analysis results in four topics, two of which are positive and the other two are negative. We found that users were satisfied with the application's recommendation system, but were dissatisfied when the filters they set during search were not applied or that reviews were not published after updates of the application. We suggest more categories can be added to the application to provide users with different experiences. In addition, it is expected that user satisfaction can be improved by identifying problems within the application, including the filter function, and checking the application environment and resolving the error occurring during the application usage.

강동현,이유노,김세은,문하현,김세윤,정진우,구현나,김현경,김길하 한국농약과학회 2023 농약과학회지 Vol.27 No.3

The susceptibility of 11 commercial insecticides against Aphis gossypii adults collected from 13 cucumber fields and nine pepper fields was evaluated. The mortality of the insecticides at the recommended concentration varied depending on the A. gossypii population in each region. Most of the insecticides except sulfoxaflor (63.8% in Gongju and 80.9% in Hamyang, respectively) showed over 90% mortality at each insecticide treatment in A. gossypii populations from cucumber fields. A. gossypii populations collected from the pepper fields showed over 90% mortality except for 3 regions (87.8% in Incheon, 53.6% in Cheongju, 72.4% in Cheonan) when treated with λ-cyhalothrin. The lethal concentrations (LC50 and LC90) of insecticides in each A. gossypii population were obtained and the resistance ratio (RR) and control efficacy index (CEI) were calculated. Hoengseong population collected from the cucumber field showed RR value of  1.0 in all insecticides except dinotefuran, and the Gyeongju population showed RR values of < 1.0 and CEI value of < 0.0004 for sulfoxaflor. The Cheonan population collected from the pepper field showed lower RR and CEI values for pyrifluquinazon, afidopyropen, and flonicamid than laboratory susceptible strain. In the box-and- whisker plot to compare the mortality of populations according to the crop fields, sulfoxaflor showed the least variation in cucumber field and imidacloprid showed the least variation in pepper fields. As a result, this study will be helpful as basic data for effective control of A. gossypii through continuous monitoring.

강동현,이유노,문하현,김세은,구현나,김현경,김길하 한국응용곤충학회 2024 한국응용곤충학회지 Vol.63 No.1

살충제 저항성 목화진딧물 집단(완주, 춘천, 고성)에 대한 3종(afidopyropen, chlorfenapyr, cyantraniliprole) 약제별 감수성과 혼용에 따른 방제 효과를 평가하였다. 3개 야외집단에 대해서 3약제 모두100배 이상의 저항성비를 보였다. 혼합제의 협력작용을 평가하기 위해 반수치사농도(LC 50 ) 을 이용한 조합지수(CI), %M (synergism) , 연합독성계수(CTC), 와들리 비율(WR), 상승비율(SR)와 사충률을 이용한 아보트 비율(AR)로 비교하였다. Afidopyropen + chlorfenapyr은 모든 야외집단에 대해서 살충활성의 증가를 보였고, chlorfenapyr + cyantraniliprole, afidopyropen + cayntraniliprole은 완주, 춘천 집단에 대해서 살충활성의 증가를 보였다. 그러나 chlorfenapyr + cyantraniliprole (CI, 1.63; %M (synergism) , 30; CTC, 64.0; WR, 0.6, AR, 0.54)과 afidopyropen + cyantraniliprole (CI, 6.7; %M (synergism) , 1; CTC, 19.8; WR, 0.2, AR ≤ 0.55)은 고성 집단에 서 길항작용을 나타내었다. 포장조건에서도 afidopyropen + chlorfenapyr, chlorfenapyr + cyantraniliprole, afidopyropen + cyantraniliprole 은 99% 이상의 높은 방제가를 보여 향후 살충제 저항성 목화진딧물 방제용 혼합제 개발에 유용하게 활용될 것이다. The susceptibility of Aphis gossypii populations collected from three fields (WJ, CC, and GS) was evaluated to three insecticides (afidopyropen, chlorfenapyr and cyantraniliprole) and three binary mixtures. Three field populations showed resistance ratios of over 100 to all insecticides. The Combination Index (CI), %M (synergism) , Co-Toxicity Coefficient (CTC), Wadley Ratio (WR), Synergism Ratio (SR) and Abbott Ratio (AR) were used to evaluate combined effect of the insecticides. Afidopyropen + chlorfenapyr (CI ≤ 0.16; %M (synergism) ≥ 94; CTC ≥ 764.5; WR ≥ 6.4; SR ≥ 6.9 and AR ≥ 1.1) showed a synergism in all filed populations. WJ and CC populations showed a synergism in all binary mixtures of insecticides, but GS population showed an antagonism for chlorfenapyr + cyantraniliprole (CI, 1.63; %M (synergism) , 30; CTC, 64.0; WR, 0.6 and AR, 0.54) and afidopyropen + cyantraniliprole (CI, 6.7; %M (synergism) , 1; CTC, 19.8; WR, 0.2 and AR ≤ 0.55). All mixtures (afidopyropen + chlorfenapyr, chlorfenapyr + cyantraniliprole and afidopyropen + cyantraniliprole) showed a control value of over 99% after 21 days of treatment in the field. This study highlights that binary mixtures of three insecticides serve as an effective control strategy for A. gossypii.
