  • This study was conducted to examine the influence of different styles of attribution to fine dust on preventive behaviors. In addition, the mediating effect of risk perception on the relationship between attribution styles and preventive behaviors was examined. Survey data was collected from 930 Korean people from a variety of ages and regions, and a hierarchical multiple regression analysis was used to test the hypothesis. The results indicated that both external and internal attribution to fine dust had a significant positive effect on preventive behavior. The multiple regression analysis revealed that both knowledge and dread had a significantly positive effect on preventive behaviors. In addition, risk perception (knowledge and dread) partially mediated the relationship between the external attribution to fine dust and preventive behavior. However, internal attribution showed only a direct effect on protection behaviors. The significance and limitations of the study were also discussed.

  • Irreparable massive rotator cuff tears can significantly impact daily life; and these types of tears can be difficult to repair completely, especially in younger patients who are more active and have higher functional requirements. Since its introduction by Mihata and the colleagues, superior capsular reconstruction (SCR) has gained popularity in the treatment of irreparable massive rotator cuff tears and has shown promising short-term results. A variety of studies have focused on the clinical and biomechanical outcomes of this procedure. This article reviews the biomechanics, indications for the surgical procedure, graft options, surgical technique, and rehabilitation from SCR.

Stem width of 'Kospeed' was similar to that of 'Florida 80' and 'Hwasan 101'. Cold tolerance of 'Kospeed' was better than that of 'Florida 80'. Dry matter (DM) yield (13,257kg/ha) of 'Kospeed' was similar to that of 'Florida 80'. In vitro dry matter digestibility (IVDMD) and total digestible nutrient (TDN) of 'Kospeed' were 73.2% and 65.3% which are 2.1% and 1.7% higher than those of 'Florida 80', respectively. Acid detergent fiber(ADF) and neutral detergent fiber (NDF) of 'Kospeed' were 29.1% and 53.1% which are 2.1% and 2.3% lower than those of 'Florida 80', respectively.

  • This study was conducted at the National Institute of Animal Science from 2010 to 2017. As a variety that is sufficiently productive in the southern regions to replace imported varieties and sufficiently cold-resistant to be cultivated in the central-northern regions, "IR605" was developed and submitted to the Korea Seed & Variety Service in an application for protection. The novel Italian ryegrass variety "IR605" is a diploid with green leaves, a semi-erect growth habit before wintering, and an erect growth habit in the spring. "IR605" was a medium maturing variety with a heading date of around May 15th. "IR605" had a flag leaf width of 9.9 mm, flag leaf length of 26.7 cm, and plant length on the heading date of 100 cm, which was approximately 5 cm longer than "Kowinearly." The stem thickness and ear length of "IR605" are 0.08 mm thicker and 0.5 cm longer than those of "Kowinearly", respectively. The cold-resistance of "IR605" was weaker than that of "Kowinearly", but strong enough to be cultivated in Pyeongchang, Gangwon province. The dry matter yield of "IR605" (9,308 kg/hectare) was 20% higher than that of "Kowinearly", which was further pronounced in the southern region of Haenam, where there was a 52% increased (p < 0.05). The in vitro dry matter digestibility of "IR605" was 68.4% at which was slightly higher than that of "Kowinearly", The total digestible nutrients was 58.5%, which was slightly lower than "Kowinearly". Overall, the feed quality characteristics of "IR605" were similar to those of "Kowinearly".

  • A new sesame variety 'Yunheuk' was developed from Yeongnam Agricultural Research Institute in 2007. A cross was made by 'Yoosung' with weak disease resistance and 'Kunheuk' with high yield capacity & quality, followed by pedigree selection, yield test and regional yield trial (RYT) by the sesame breeding team at the National Institute of Crop Science and Yeongnam Agricultural Research Institute up to 2007. The variety showed higher lodging resistance and more dark seed coloring rather than that of check variety 'Yangheuk'. Average stem length and the number of capsules per plant is 118 cm, 79 cm respectively. Its 1,000 grains weight is about 2.67 g indicating 0.10 g lower than that of 'Yangheuk', and its oil content is about 46.4%. 'Yunheuk' also contains total 2.59 mg/g of such lignans as sesamin and sesamolin. And its dark color density ($L^*$ Value) of seed coat is 22.43 which was about 10% lower than that of check variety. The average yield of 'Yunheuk' was 99.9 kg per 10a at the national-wide regional performance.

  • A new peanut variety 'Daan'(Arachis hypogaea ssp. hypogaea L.) was developed at the Department of Southern Area Crop Science, National Institute of Crop Science (NICS) in Milyang 2014. This was developed from the cross between 'Iksan 31' with Virginia typed short stem and 'Dakwang' with Shinpung-typed larger grain. 'Daan' which is a Shinpung plant type had 13 branches per plant and its length of main stem was 44cm. Each pod has two grains with brown testa and long ellipse-shaped large kernel. Its yield components showed 34 pods per plant, 127 g of 100-seed-weight and 75% of pod shelling ratio in the regional yield trials (RYT). Seed quality showed 47.8% of crude oil and 28.3% of protein content. This variety showed resistant to early leaf spot and had more resistant to late leaf spot, stem rot and lodging, compared to reference variety. In the regional yield trials for 3 years 'Daan' was more productive than reference variety by 16% with 5.00 MT/ha for grain production.

  • Myeloid-derived suppressor cells (MDSCs) actively suppress immune cells and have been considered as an impediment to successful cancer immunotherapy. Many approaches have been made to overcome such immunosuppressive factors and to exert effective anti-tumor effects, but the possibility of using medicinal plants for this purpose has been overlooked. Korean red ginseng (KRG) is widely known to possess a variety of pharmacological properties, including immunoboosting and anti-tumor activities. However, little has been done to assess the anti-tumor activity of KRG on MDSCs. Therefore, we examined the effects of KRG on MDSCs in tumor-bearing mice and evaluated immunostimulatory and anti-tumor activities of KRG through MDSC modulation. The data show that intraperitoneal administration of KRG compromises MDSC function and induces T cell proliferation and the secretion of IL-2 and IFN-${\gamma}$, while it does not exhibit direct cytotoxicity on tumor cells and reduced MDSC accumulation. MDSCs isolated from KRG-treated mice also express significantly lower levels of inducible nitric oxide synthase and IL-10 accompanied by a decrease in nitric oxide production compared with control. Taken together, the present study demonstrates that KRG enhances T cell function by inhibiting the immunosuppressive activity of MDSCs and suggests that although KRG alone does not exhibit direct anti-tumor effects, the use of KRG together with conventional chemo- or immunotherapy may provide better outcomes to cancer patients through MDSC modulation.

  • Condensin is not only responsible for chromosome condensation, but is also involved in double-strand break (DSB) processing in the cell cycle. During meiosis, the condensin complex serves as a component of the meiotic chromosome axis, and mediates both proper assembly of the synaptonemal complex and DSB repair, in order to ensure proper homologous chromosome segregation. Here, we used the budding yeast Saccharomyces cerevisiae to show that condensin participates in a variety of chromosome organization processes and exhibits crucial molecular functions that contribute to meiotic recombination during meiotic prophase I. We demonstrate that Ycs4 is required for efficient DSB formation and establishing homolog bias at the early stage of meiotic prophase I, which allows efficient formation of interhomolog recombination products. In the Ycs4 meiosis-specific allele (ycs4S), interhomolog products were formed at substantial levels, but with the same reduction in crossovers and noncrossovers. We further show that, in prophase chromosomal events, ycs4S relieved the defects in the progression of recombination interactions induced as a result of the absence of Rec8. These results suggest that condensin is a crucial coordinator of the recombination process and chromosome organization during meiosis.
