<P>We provide a broad view of East Asian summer monsoon (EASM) precipitation and their changes in the 21st century under the representative concentration pathway RCP4.5 and RCP8.5 scenarios using a high‐resolution (at 40 km) atmospheric general circulation model (AGCM). The simulated fields are validated against the multiple observational data sets in the reference period (1979–2008). Validation of seasonal simulated global climatology and EASM precipitation, annual cycle and various circulation fields including 25 individual Coupled Model Intercomparison Project phase 5 (CMIP5) and CMIP5 MME suggests that AGCM can be used to study the future projected characteristics of EASM. An investigation of uncertainty in precipitation shows larger values in the regions of high‐precipitation belt and low terrain.</P><P>Future projections are categorized as near (2010–2039), mid (2040–2069) and far (2070–2100) futures. The model projects an increased summer precipitation of about 3.2% (2.3%) in near future, about 4.5% (4.5%) in mid‐future and about 2.4% (2.3%) in far future over East Asia region under RCP4.5 (RCP8.5) scenarios when compared to the reference period. As far as regional landmasses are concerned, model projects a gradual increase in the range of 5–15% over northeast China, coastal regions of southern China, Korea and Japan regions and a decrease of about 5–10% over southeastern and northwest parts of East Asia during the 21st century. The projected increase of EASM can be attributed to an increase in atmospheric moistures (relative humidity) over the east coast of China, Korea and northeast China and north and northwestwards enhancement of eddy geopotential height. Extreme events are examined by using various precipitation indices over EASM regions. Results indicate that the indices of heavy precipitation are projected to increase (both frequency and intensity) over Korea, Japan and northeast China in the range of 5–20%, indicating strong sensitivity of EASM to global warming.</P>

Grapevines are cultivated globally, and are also damaged by a large number of insect pests especially including leafhoppers. Leafhoppers are one of the important insect pests on various crops including grape. Among them, the genus Arboridia Zachvatkin (Hemiptera: Auchenorrhyncha: Cicadellidae: Typhlocybinae) was known as insect pests against grape farming. Eighty species were described in the genus in the world, and eight species were recorded in the Korean Peninsula so far, which are: Arboridia apicalis, A. kakogawana, A. koreacola, A. maculifrons, A. nigrigena, A. okamotonis, A. silvarum, A. suzukii. Among them, A. apicalis, A. kakogawana, A. maculifrons, A. nigrigena, A. suzukii have been known as important insect pests on grapes. In this talk, we propose a new species from the Korean Peninsula, and confirmed two new records: A. agrillacea and A. lunula. Additionally we present differential diagnoses of the Arboridia species damaging on grapevines for the field of applied biology.

Left ventricular (LV) hypertrophy caused by aortic valve stenosis (AS) leads to cardiovascular morbidity and mortality. We sought to determine whether aortic valve replacement (AVR) decreases LV mass and improves LV function. Materials and Methods: Retrospective review for 358 consecutive patients, who underwent aortic valve replacement for degenerative AS between January 1995 and December 2008, was performed. There were 230 men and 128 women, and their age at operation was 63.2±10 years (30∼85 years). Results: There was no in-hospital mortality, and mean follow-up duration after discharge was 48.9 months (2∼167 months). Immediate postoperative echocardiography revealed that LV mass index and mean gradient across the aortic valve decreased significantly (p<0.001), and LV mass continued to decrease during the follow-up period (p<0.001). LV ejection fraction (EF) temporarily decreased postoperatively (p<0.001), but LV function recovered immediately and continued to improve with a significant difference between preoperative and postoperative EF (p<0.001). There were 15 late deaths during the follow-up period, and overall survival at 5 and 10 years were 94% and 90%, respectively. On multivariable analysis, age at operation (p=0.008), concomitant coronary bypass surgery (p<0.003), lower preoperative LVEF (<40%) (p=0.0018), and higher EUROScore (>7) (p=0.045) were risk factors for late death. Conclusion: After AVR for degenerative AS, reduction of left ventricular mass and improvement of left ventricular function continue late after operation.

Understanding the genetics underlying heading date and yield-related traits is essential in wheat breeding formaximizing productivity under different environments. Using doubled haploid lines derived from two Korean wheat cultivars, weidentified seven stable quantitative trait loci (QTLs) for yield-related traits, i.e., days to heading date (QDhd.jbnu-3B, QDhd.jbnu-6B,and QDhd.jbnu-7D), culm length (QCl.jbnu-6A), thousand kernel weight (QTkw.jbnu-6A), kernels per spike (QKps.jbnu-3B) and testweight (QTw.jbnu-1A). Compared to the lines carrying the allele for late heading, those carrying the allele for early heading atQDhd.jbnu-3B, QDhd.jbnu-6B, and QDhd.jbnu-7D headed 3.1, 2.0, and 1.7 days earlier, respectively. Interestingly, when the allelesfor early heading at the three QTLs were accumulated, heading date was accelerated by approximately one week, indicating that theseQTLs provide useful genetic resources to fine-tune heading date. However, as the alleles for early heading at all three QTLs wereassociated with decreased kernels per spike, caution is required when deploying them to minimize the negative impacts on yield. Ourstudy provides useful information for developing wheat cultivars with optimal heading date and enhanced productivity.

본 연구는 유아를 대상으로 한 영양교육의 중재효과를 평가하고, 과일·채소의 선호도 및 영양지식 향상에 효과적인 영양교육 유형을 분석하기 위해 체계적 문헌고찰과 메타분석을 수행하였다. 메타분석의 효과크기 결과에 따르면 유아 대상 영양교육은 과일·채소 선호도 및 영양지식을 유의적으로 향상시켰으며, 일반영양교육 보다는 과일·채소 중심 영양교육이 유아의 과일·채소 선호도 및 영양지식 향상에 더 효과적이었다. 또한 유아의 과일·채소 선호도 및 영양지식 향상을 위해서는 원예활동, 요리활동 및 오감활동 등의 직접 노출 활동을 포함하는 영양교육이 더욱 효과적이라는 것을 확인할 수 있었다. 본 연구는 유아대상 영양교육의 효과를 입증했을 뿐만 아니라, 유아의 과일·채소 선호도 및 영양지식 향상에 가장 효과적인 영양교육의 형태를 도출했다는 점에서 의의가 있다. Purpose: A systematic review and meta-analysis of nutrition educational intervention studies was performed to assess the association between nutrition education intervention and fruit & vegetable (F&V) preferences and nutrition knowledge in preschool children. Methods: The relevant studies of nutrition education intervention and F&V preferences and nutrition knowledge published from January 2000 to June 2020 were located using PubMed, Web of Science, Cochrane Library, Research Information Sharing Service, Korean Studies Information Service System databases, and lists of references. A random-effects meta-analysis was conducted to estimate the standardized mean difference with a 95% confidence interval (CI). Subgroup analyses were performed to identify the association between nutrition education and F&V preferences and nutrition knowledge. Results: The results show that the effect sizes (ES) of F&V preferences and nutrition knowledge of preschool children were 0.31(95% CI, 0.23, 0.39), and 1.69(95% CI, 1.27, 2.12), respectively. The result of subgroup analysis, nutrition education focused on F&V (F&V preferences, ES: 0.32; nutrition knowledge, ES: 2.09) presented a slightly larger effect than general nutrition education (F&V preferences, ES: 0.26; nutrition knowledge, ES: 1.62). As for the type of exposure to F&V, direct exposure education (F&V preferences, ES: 0.40) had a greater effect than indirect exposure (F&V preferences, ES: 0.26). This meta-analysis showed that nutrition education intervention had positive effects on the F&V preferences and nutrition knowledge in preschool children. Conclusion: In conclusion, from the meta-analysis and subsequent subgroup analysis, we found that varied types of nutrition education intervention had varying effects on F&V preferences and nutrition knowledge in preschool children.
