Our study was carried out to determine the control efficacy of sodium hypochlorite (NaOCl) for violet root rot caused by Helicobasidium mompa in apple. The experiment was conducted in the farm located at Chungbuk province in South Korea from 2014 to 2016. When infected apple trees were treated at least two or three times with 31.25 and 62.5 ml/l available chlorine content in NaOCl, it greatly increased the rooting of rootstock, and restored the tree crown density by 44.4-60.5%. In addition, the number of commercial fruit setting was increased by 54.3-64.5%, and the total starch content in shoots was significantly higher than other non-treated apple trees. However, the untreated disease control and thiophanate-methyl WP treated trees showed the symptom of dieback. Therefore, our results indicate that the drenching treatment of NaOCl with 31.25-62.5 ml/l available chlorine content more than two times from late fall to early spring could effectively control the violet root rot and recover tree vigor up to 60%.

In this study, we assessed meteorological and agricultural drought based on the SPI(Standardized Precipitation Index), SMP(Soil Moisture Percentile), and SMDI(Soil Moisture Deficit Index) indices using satellite-based TRMM(Tropical Rainfall Measuring Mission)/GPM(Global Precipitation Measurement) images at the province of Chungcheongbuk-do. The long-term(2000-2015) TRMM/GPM precipitation data were used to estimate the SPI values. Then, we estimated the spatially-/temporally-distributed soil moisture values based on the near-surface soil moisture data assimilation scheme using the TRMM/GPM and MODIS(MODerate resolution Imaging Spectroradiometer) images. Overall, the SPI value was significantly affected by the precipitation at the study region, while both the precipitation and land surface condition have influences on the SMP and SMDI values. But the SMP index showed the relatively extreme wet/dry conditions compared to SPI and SMDI, because SMP only calculates the percentage of current wetness condition without considering the impacts of past wetness condition. Considering that different drought indices have their own advantages and disadvantages, the SMDI index could be useful for evaluating agricultural drought and establishing efficient water management plans.

본 연구는 충북지역의 대표 관광목적지인 청남대의 방문동기와 만족도 간 영향관계에 있어 지역주민과 관광객 집단 간 차이를 분석하는데 목적이 있다. 문헌연구를 통해 구성한 설문지를 바탕으로 청남대를 방문한 경험이 있는 충북권 지역주민 200부, 충북 외 지역에 거주하고 있는 관광객 200부의 유효표본을 확보하여 분석에 활용하였다. 분석결과, 동기와 만족도간 영향관계는 전체표본, 지역주민, 관광객 집단에 따라 차이가 있는 것으로 나타났으며, 모든 집단에서 공통적으로 자연휴식성과 편리성 요인이 만족도에 긍정적으로 크게 영향을 미치는 것으로 나타났다. 동기와 만족도 간 영향관계에 있어 지역주민은 자연휴식성, 편리성, 역사성, 관계성 등 4개 동기요인, 관광객은 자연휴식성, 편리성 등 2개 동기요인이 만족도에 유의한 영향을 미치는 것으로 나타나 집단 간 차이가 있음을 보여주었다. 연구결과를 바탕으로 이론적 실무적 시사점을 제시하였으며, 후속 연구과제를 제안하였다.

This study aims to investigate and analyze the actual conditions of the ecological ponds built in the campus sites of the elementary, middle and high schools which currently manage ecological ponds in order to find problems and directions for improvement concerning the management of the ponds as a way to build nature-friendly ecological ponds which can be used as an ecological work-study site on school campus: this study also intends to provide systematic and technological directions for the management and operation of the ecological pond. This study has selected 10 schools in North Chungcheong Province, where ponds are constructed, and investigated actual conditions of the ponds based on the survey, analysis, and evaluation standards compatible with the school environments, and finally judged the general relevancy of the ponds. The results of this study make us conclude that the most important issue to be considered in the processes of selection and investigation for school ecological pond is the location of the pond.

Background: In South Korea, African swine fever virus (ASFV) has spread among wild boars through Gangwon-do to Dangyang-gun, Chungcheongbuk-do on the southern border of Gangwon-do. To prevent the spread of ASFV to African swine fever (ASF)-free areas, it is necessary to identify areas with a high probability of finding ASFV-infected carcasses and to reduce the density of wild boars in those areas. In this study, we described the propagation trend of ASFV among wild boars, constructed the habitat suitability maps for ASFV-infected carcasses, and suggested areas with a high probability of finding ASFV-infected carcasses and an important route of ASFV transmission. Results: Despite the active quarantine policies in Korea to prevent the spread of ASFV through wild boars, there was no significant difference in the monthly average of number of ASFV-infected carcasses observed between 2020 and 2021. The ASFV-infected carcasses were found more in winter and spring (January to April). Since the first ASF outbreak in wild boars on October 2, 2019, the maximum width of ASFV-infected carcass distribution area was 222.7 km for about 26 months till November 20, 2021. The habitat suitability map, based on GPS coordinates of ASFV-infected wild boar carcasses, shows that highly detectable areas of ASFV-infected carcasses were sporadically dispersed in western and southwestern parts of Gangwon-do, and ranged from north to south of the province along the Baekdudaegan Mountains, whereas poorly detectable areas ranged along the north to the south in the middle parts of the province. Conclusions: Our suitability model, based on the GPS coordinates of ASFV-infected carcasses, identifies potential habitats where ASFV-infected carcasses are likely to be found and ponential routes where ASFV is likely to spread. Among ASF-free areas, the areas with high suitability predicted in this study should be given priority as survey areas to find ASFV-infected carcasses and hunting areas to reduce wild boar populations.

This study found out the influence of CCTV recognition and Self-efficacy on job satisfaction for 275 child care teachers working at daycare centers in Chungcheongbuk-do Province, and verified the regulation effect of Self-efficacy in the process. SPSS(Statistical Package for Social Science) 22.0 was used for data analysis. The results of the study are as follows: First, it was found that factors such as the guarantee of child's right, the guarantee of teachers' rights, and the self - efficacy were influential factors on the job satisfaction of the child care teachers. Second, it has been confirmed that the guarantee of teachers' rights and self-efficacy on the job satisfaction of child care teachers have a regulation effect. This study can be meaningful in that it provided basic data to enhance the quality of child care services by analyzing the factors of influence on the job satisfaction of child care teachers and presenting specific measures accordingly.
