Non-destructive estimation of leaf area is a more efficient and convenient method than leaf excision. Thus, several models predicting leaf area have been developed for various horticultural crops. However, there are limited studies on estimating the leaf area of strawberry plants. In this study, we predicted the leaf areas via nonlinear regression analysis using the leaf lengths and widths of three-compound leaves in five domestic strawberry cultivars (‘Arihyang’, ‘Jukhyang’, ‘Keumsil’, ‘Maehyang’, and ‘Seollhyang’). The coefficient of determination (R2) between the actual and estimated leaf areas varied from 0.923 to 0.973. The R2 value varied for each cultivar; thus, leaf area estimation models must be developed for each cultivar. The leaf areas of the three cultivars ‘Jukhyang’, ‘Seolhyang’, and ‘Maehyang’ could be non-destructively predicted using the model developed in this study, as they had R2 values over 0.96. The cultivars ‘Arihyang’ and ‘Geumsil’ had slightly low R2 values, 0.938 and 0.923, respectively. The leaf area estimation model for each cultivar was coded in Python and is provided in this manuscript. The estimation models developed in this study could be used extensively in other strawberry-related studies.

The purpose of this research is to examine the significance of peer-peer interactions on L1 discussions for L2 reading tasks. This research was designed to see how college EFL students interact during a L1 group discussion assigned as part of an L2 reading task by a means of CA (conversation analysis). Five college EFL students engaged in an L1 group discussion on L2 reading comprehension questions and their conversations were video-recorded for transcription. The peer-peer interaction CA analyzed discussions through a turn-taking system and contextualization cues and has provided pedagogical implications. Observed interactions among students showed that a team leader playing a role as a mediator attempted to focus on the issues arising during the discussion to solve and foster the engagement from other team members. The findings of this study suggest that students effectively find the best ways of reaching desirable conclusions through negotiation-driven interactions. Group discussions with L1 can encourage students to use their linguistic resources to perform the L2 task effectively, which leads to successful completion of the given tasks.

최근 다양한 유기재배 작물의 뿌리를 가해하는 굼벵이류의 피해가 증가하고 있으나, 굼벵이류는 토양 내 발생하는 특징으로 인해 발생시기 및 그 종류에 대한 확인이 어려운 해충이다. 피해를 끼치는 굼벵이의 발생을 파악하기 위해 고구마 유기재배지에 페로몬 트랩을 이용하여 굼벵이의 성충의 종류 및 발생 동향을 조사하였다. 조사지는 무안 유기재배농가와 국립농업과학원 완주군 포장에서 이루어졌다. 3종의 풍뎅이 페로몬 루어를 유인제로 사용하였으 며 6월 초부터 8월 말까지 조사지에 트랩을 설치하여 포획된 풍뎅이를 수집하여 동정을 하였다. 유기재배포장에서 포획된 종은 큰검정풍뎅이, 콩풍뎅이, 청동풍뎅이, 녹색콩풍뎅이, 별줄풍뎅이 등의 풍뎅이와 흰점박이꽃무지 등이 주로 채집되었다. 유기재배 고구마포장에서 풍뎅이 발생소장을 조사한 결과 최대로 발생한 시기는 7월초였다.

Phalaenopsis ‘Blanc Rouse’ 품종은 국립원예특작과학원에서 2013년도에 육성한 신품종이다. 이 품종은 2007년에 백색 바탕에 분홍색의 소형 P. ‘KV 600’ 품종을 모본으로 하고 진한 핑크색의 P. ‘Kang 1’ 품종을 부본으로 교배시킨 후대 계통 중에서 선발하였다. 2010년에 화색, 초장, 화경 및 식물체의 생육상태 등을 고려하여 1차 선발 후 2013년에 2차 특성검정을 통하여 품종의 안정성과 균일성을 확인하고 ‘Blanc Rouse’로 명명하였다. 이 품종은 흰색바탕에 자주색 순판을 가졌으며 꽃 가운데 분홍색의 줄무늬가 크게 형성되어 있는 품종이다. 화형은 꽃잎과 꽃받침이 평편한 모양이고 꽃의 길이와 폭은 4.3cm, 4.8cm로 소형이다. 꽃대가 평균 2개 발생하며 복총상 화서로 화서당 꽃 수가 39.4개로 볼륨이 있어 소형분화에 적합하다. 자연 개화시기는 11월 하순으로 개화가 빠른 조생종 이다. 잎의 길이와 폭은 각각 17.3, 6.2cm이며 엽형은 수평이다. 기내 증식력이 높고 변이가 거의 없으며 내병성이 강하여 재배관리가 용이하다.

Fumigation activity of Frankliniella occidentalis, western flower thrips, and phytotoxicity were evaluated with phosphine(PH3) and ethyl formate (EF) in the asparagus. Fumigation activity of PH3 and EF showed in the order of egg (64.7 mg·h/Land 132.9 mg·h/L), nymph (5.5 mg·h/L and 14.8 mg·h/L), and adult (3.8 mg·h/L and 14.7 mg·h/L) respectively at 5˚C in12 L desiccator. The adsorption of PH3 was 24% at 5˚C. However, the adsorption of EF increased sharply to 98% at 5˚C.PH3 showed 100% control for all development stage of F. occidentalis with 4g/m3 in 0.65m3 at 2˚C for 48h exposure. Thephytotoxicity was not found. The results revealed that the EF is highly absorbable in asparagus, so it is not suitable as afumigant, but PH3 is considered to be suitable as an alternative MB fumigant for control of the F. occidentalis in asparagus.

As the hangover relieving drink market has been expanded, there have been efforts to produce traditional drinks that can be easily taken through reducing material costs after finding materials with high alcohol-degrading activity from agricultural products and manufacturing drinks in a way to produce sikhye. Studies were made to know quality, the ability to relieve hangover and preference of drinks for which seven kinds of agricultural products, including shiitake mushrooms, were added in the forms of fresh juice, extracts and powder. Farm products showed the highest acetaldehyde dehydrogenase (ALDH) when they were added in the form of powder before saccharification and shiitake mushrooms showed the highest enzyme activity when they were added in the form of powder. When added in the form of powder, people showed the lowest preference except when radish and hericium erinaceum were added. When bear puree was added to a mixture of powdered shiitake mushrooms, radish, bean sprouts and dadagi cucumber, enzyme activity got higher and people showed higher preference. An experiment of animal behaviors showed that the mixture had a high ability to relieve hangover in one or two hours after 10% or 40% alcohol was orally administered to mice due to long traveling distance of mice.

Ethyl formate (EF) and phosphine (PH3) is an alternative fumigant to methyl bromide (MB). For applying import sweet pumpkins in Korea, the efficacy of EF and PH3 was evaluated on Tetranychus urticae adult and egg stage which is pest in sweet pumpkins. The eggs of T. urticae were more tolerance than adults in both EF and PH3. When T. urticae eggs were treated with EF for 4 hrs, LCT99=107.63 mg/L and LCT99=45.37 mg/L at 5°C and 20°C, respectively. PH3 treatment at 5°C and 20°C for 24 hrs, eggs were controlled LCT99=49.44 mg/L and LCT99=17.23 mg/L, respectively. The mixed treatment of EF and PH3 showed no significant synergistic effect on T. urticae. However, EF (80 mg/L) and PH3 (4 mg/L) treatment did not cause any external phytotoxicity damages in sweet pumpkin even when treated with the maximum amount of fumigant at 5℃ and 20℃ for 24hrs.
