본 연구는 학부모들이 보습학원이라는 형태의 사교육에 참여하는 논리를 밝히고자 하는데 목적이 있다. 연구 목적을 이루기 위해 Lareau(2003; 2012)가 제시한 문화적 논리(cultural logic)의 개념을 통해 현상을 이해하고자 하였다. 문화적 논리는 개인의 행동을 이해하기 위한 분석틀로, 개인의 행동은 사회경제적 상황을 바탕으로 한 문화적 틀 안에서 이해될 수 있다는 이론이다. 본 연구는 우리나라 학부모들의 문화적 논리가 ‘자녀교육을 통한 자녀에 대한 책임의식’ 담론을 중심으로 형성되어 있으며, 자녀에 대한 책임은 다름 아닌 ‘사교육’을 중심으로 행해진다는 데 주목한다. 그러나 ‘사교육’에 참여하는 양태는 모든 학부모에게서 동일하게 드러나지는 않는다. 보습학원에 참여하는 이른바 ‘보습학원엄마’는 자녀에게 사교육 을 제공해주어야 한다는 기본적인 논리에 더해, 다양한 양질의 사교육을 제공해주어야 한다는 부차적인 책임의식 또한 느끼고 있다. 이는 기존 다수 논의 되었던 중산층의 사교육 참여담론과 일치하는 부분으로, 보습학원엄마 또한 중산층의 사교육 참여 문화적 논리를 인지하며 때로는 받아들이는 것으로 드러난다. 그러나 다른 한편으로는 자신이 속해있는 사회경제적 자본 아래에서는 보습학원에 보내는 것이 현 상황에서 가장 적당한 선택지라는 인식 또한 강하게 자리 잡고 있다. 그러므로 보습학원 엄마들은 자녀에게 좋은 사교육을 제공해주어야 한다는 부모의 책임의식과 자신이 보유한 사회경제적 제약 사이에서 내적으로 지속적으로 충돌하고 갈등하는 과정을 겪는다. 그러나 충돌과 갈등은 방치되지 않으며, 또한 해결되지도 않는다. 다만 잠시동안 일시적인 타협이 이루어지는데, 이는 다름 아닌 보습학원이라는 형태로 제공되는 사교육의 지점에서 잠시 소강을 맞게 된다. 즉, 보습학원은 부모의 책임의식과 사회경제적 제약의 타협점으로 역할한다고 볼 수 있다. 연구 결과를 바탕으로 본 논문은 기존 논의되었던 교육열 담론이나 중산층 중심의 과도한 교육개입의 논의를 넘어서서 사교육 현상을 다양한 각도로 이해할 수 있는 시각을 제시한다. 이 같은 확장을 통해 우리나라에 명실공히 존재하는 사교육이라는 ‘교육현상’을 교육적 틀 안에서 새로이 논의할 가능성을 연다는 데 본 연구의 의의가 있다.

The purpose of this study is to examine the circumstances of teachers’ struggles in relation to the social context of education. Teachers have endured troubled school fields for a long time. However, studies so far have not been very interested in how teachers have endured or how changes in school contexts relate to their struggle. Current research focuses on the professional development of teachers or deal with the difficulties of specific teachers in specific situations. These studies are limited in their ability to interpret and establish connections between teachers’ struggles and the socio-cultural context. Therefore, the purpose of the study was to view teachers’ struggles as a socio-cultural phenomenon rather than an issue specific to individual teachers. In addition, the focus was on the connection between teachers’ struggles and the structural context of the Korean education. The study includes Lee Sun-young (pseudonym), a teacher with ten years of experience, who faced challenges in her school. The study was conducted with a narrative inquiry methodology. The findings revealed the narrative structures of “persuaded career path”, “classroom enduring alone”, “teachers without communication”, and “hiding oneself”. Based on the findings, the discussion highlights that the culture of an “unsupportive school” fosters the emergence of the “self-blaming teacher” within the context of an “isolated classroom.” In other words, the school structure in which individual teachers are responsible for everything in the classroom isolated them and made themselves devalued. Therefore, it is suggested that fostering relationships built on recognition and mutual respect is necessary. This study contributes to understanding the relationship between personalities, school culture, and structure in relation to teachers’ struggles. It also addresses and narrows the academic gap in the literature on teachers’ struggles.

Due to abnormal weather conditions caused by climate change, natural disasters and damages are gradually increasing around the world. Global climate change as accompanied by warming is projected to exert adverse impact on production of potato, which is known as cool season crop. Even though, role of potato as a food security crop is expected to increase in the future, the climate change impacts on potato and adaption strategies are not sufficiently established. Therefore, this study was conducted to analyze the damage pattern of potatoes due to high temperature treatment and to evaluate the response of cultivars. T he high temperature treatment (35~38℃) induced heat stress by sealing the plastic house in midsummer (July), and the quantity and quality characteristics of potatoes were compared with the control group. T otal yield, marketable yield (>80 g) and the number of tubers per plants decreased when heat treatment was performed, and statistical significance was evident. In the heat treatment, 'Jayoung' cultivar suffered a high heat damage with an 84% reduction in yield of >80 g compared to the control group. However, in Jopung cultivar, the decrease was relatively small at 26%. Tuber physiological disturbances (Secondary growth, Tuber cracking, Malformation) tended to increase in the heat stress. Under heat conditions, the tubers were elongated overall, which means that the marketability of potatoes was lowered. T he tuber firmness and dry matter content tended to decrease significantly in the heat-treated group. T herefore, the yield and quality of tubers were damaged when growing potatoes in heat conditions. T he cultivar with high heat adaptability was 'Jopung'. T his result can be used as basic data for potato growers and breeding of heat-resistant cultivars.

The current study was performed to investigate the effect of recycling coir substrates on the growth, fruit yield, and quality of strawberry plants. Analysis of physical properties revealed that the pH of a fresh coir substrate was 5.04 while those of substrates reused for one and two years were 5.20 and 5.33, respectively. The electrical conductivity (EC) of a new substrate was as high as 4.58 dS·m−1. This can cause salt stress after transplanting. The EC tended to decrease as the substrate was recycled, and the EC of a two-year recycled substrate was 1.48 dS·m−1. The fresh substrate had lower nitrogen and calcium concentrations, but higher phosphate, potassium, and sodium concentrations than the recycled coir substrate. The coir substrates recycled for one or two years maintained better chemical properties for plant growth than the fresh substrate. Strawberry growth varied depending on the number of years that the coir substrate was recycled. In general, strawberries grown in substrates that had been reused for two years did better than those grown in substrates that had been reused once or were fresh. Ninety days after transplanting, a plant grown in a substrate that had been reused for two years contained 25 leaves, which was 3.6 more than with a fresh substrate. In addition, the plants grown in a substrate that had been reused for two years exhibited larger leaf areas than those grown in other substrates. Coir substrates that had been reused for one year increased the number and area of leaves, but not as much as the substrate that had been reused for two years. One- and two-year reused coir substrates increased the weight of strawberries produced relative to the unused substrate, but the difference was not statistically significant. The plants grown in two-year reused substrates were longer and wider, as well. Also, the number of fruits per plant was higher when substrates were reused. Specifically, the number of fruits per plant was 28.7 with a two-year reused substrate, but only 22.2 with a fresh substrate. The fruit color indices (as represented by their Hunter L, a, b values) were not considerably affected by recycling of the coir substrate. The Hunter L value, which indicates the brightness of the fruit, did not change significantly when the substrate was recycled. Neither Hunter a (red) nor b (yellow) values were changed by recycling. In addition, there were no significant changes in the hardnesses, acidities, or soluble solid-acid ratios of fruits grown in recycled substrates. Thus, it is thought that recycling the coir substrate does not affect measures of fruit quality such as color, hardness, and sugar content. Overall, reuse of coir substrates from hydroponic culture as high-bed strawberry growth substrates would solve the problems of new substrate costs and the disposal of substrates that had been used once.

봄감자 재배기간이 가을감자 품종의 생육, 수량 및 가공품질에 미치는 영향

이규빈,최장규,권도희,이재연,이희태,진용익 한국자원식물학회 2024 한국자원식물학회지 Vol.37 No.2

적 요국내에서 감자는 주로 반찬이나 부식으로 이용해 왔지만 최근에는 칩이나 프렌치프라이 등 스낵이나 간식으로 이용이 증가하고 있다. 가공원료용 생감자를 사용하여 감자를 가공하는 것에 대한 수요는 높지만 감자를 2기작으로 특히 가을에 재배하였을때 가공품질이 어떻게 달라지는 지에 대한 연구는 부족한 실정이다. 따라서 본 연구는 봄감자 재배기간을 달리하여 가을감자를재배하였을 때 생육과 수량 및 가공품질에 미치는 영향을 구명하고자 수행하였다. 봄감자 파종 후 수확을 70일, 80일, 90일, 100 일 총4번에 거쳐 하였으며, 이를 활용하여 각각 강릉과 서천 지역에서 가을재배를 수행하였다. 지상부 출현율은 봄감자 재배기간이 짧은 씨감자를 가을재배 했을 때 높아지는 경향이었다. 경장은 봄재배 기간이 80일 및 90일인 씨감자를 강릉 지역에서 가을재배했을 때 47.2~48.9로 다른 처리에 비해 컸다. 재배기간에따른 경수와 엽색은 통계적 유의성이 없었다. 수확시기에 따라괴경수, 괴경무게, 수량 및 상서수량은 통계적 유의성이 없었으며 품종에 따른 차이는 뚜렷하게 나타났다. 괴경 무게는 강릉에서는 새봉 품종이, 서천에서는 은선 품종이 우수하였다. 전분 함량은 봄에 80일간 재배한 씨감자를 강릉 지역에서 가을재배 했을 때 7.9%로 함량이 높았으며, 서천 지역에서는 유의성이 나타나지 않았다. Glucose 함량은 재배기간에 따라 뚜렷한 차이를 보였는데, 봄감자 재배기간이 긴 씨감자를 가을재배에 이용할 경우 그 함량이 높아졌다. 감자를 2기작으로 재배 시 봄감자 재배기간이 괴경의 생육, 수량 및 가공품질에 미치는 영향에 대해 연구한 결과, 재배기간에 따른 차이는 크지 않았고, 품종에 따른차이가 뚜렷하였다. 은선 품종은 가을재배 시 지상부 생육 및 수량이 뛰어났고, 가공품질은 새봉 품종이 우수하였다. Abstract - In Korea, potatoes have served as a side dish, but their role as snacks, such as chips or French fries, has recently gained traction. While there is a high demand for processing potatoes, there remains a dearth of research on the impact of double cropping, particularly during autumn, on processing quality. Therefore, this study was conducted to determine the effects of different spring potato cultivation periods on growth, yield, and processing quality during autumn cultivation. Following spring planting, harvest was carried out four times: 70 days, 80 days, 90 days, and 100 days. Subsequently, autumn cultivation was carried out in Gangneung and Seocheon regions using these seed potatoes. Results showed an increase in above-ground emergence rate with shorter spring growing period. When seed potatoes with a spring cultivation period of 80 and 90 days were grown in the autumn in the Gangneung region, the stem length was 47.2 to 48.9, which was greater than that of other treatments. However, stem number and leaf color (SPAD) showed no significant differences across cultivation periods. The number of tubers, tuber weight, yield, and marketable yield did not vary significantly with cultivation periods but described clear cultivar dependent differences. The tuber weight of the Saebong cultivar in Gangneung and the Eunseon cultivar in Seocheon was superior. The starch content peaked at 7.9% when seed potatoes grown for 80 days in the spring were harvested after autumn cultivation in the Gangneung region, but there was no significant differences in the Seocheon region. Glucose content showed a clear difference depending on the cultivation period, increasing with longer spring cultivation period during autumn cultivation. In conclusion, as a result of the effect of the spring potato cultivation period on the growth, yield, and processing quality of tubers when cultivating potatoes in double-cropping, the differences depending on the cultivation period were insignificant, while cultivar-based disparities were pronounced. The Eunseon cultivar exhibited robust above-ground growth and yield, while the Saebong cultivar demonstrated excellent processing quality.

The purpose of this study was to investigate the effects of defoliation treatment on the growth and yield of strawberries. There was a remarkable growth in the above-ground part and root of untreated strawberry plants possibly due to higher amount of photosynthesis, while overall plant growth was suppressed as the level of defoliation treatment increased. In both the "Seolhyang" and "Maehyang" cultivars examined, defoliation treatment resulted in small fruits and a low number of fruits per plant. Notably, 50% defoliation significantly reduced the number of fruits per plant to 8.2, compared to 13.8 in untreated plants. Defoliation treatment also negatively influenced the fruit quality including color, sugar content, and solid-acid rate. However, no significant changes in fruit firmness was observed in either cultivar. Therefore, retaining enough leaves without defoliation treatment can be important to increasing fruit yield, producing high quality fruits and saving labor required for defoliation.

In recent years, there has been a growing interest in deep learning-based animal pose estimation, especially in the areas of animal behavior analysis and healthcare. However, existing animal pose estimation techniques do not perform well when body parts are occluded or not present. In particular, the occlusion of dog tail or ear might lead to a significant degradation of performance in pet behavior and emotion recognition. In this paper, to solve this intractable problem, we propose a simple yet novel framework for pet pose estimation where pet pose is predicted on an outpainted image where some body parts hidden outside the input image are reconstructed by the image inpainting network preceding the pose estimation network, and we performed a preliminary study to test the feasibility of the proposed approach. We assessed CE-GAN and BAT-Fill for image outpainting, and evaluated SimpleBaseline for pet pose estimation. Our experimental results show that pet pose estimation on outpainted images generated using BAT-Fill outperforms the existing methods of pose estimation on outpainting-less input image.
