Endogenous retroviruses (ERVs) have been integrated into vertebrate genomes and have momentously affected host organisms. Horses (Equus caballus) have been domesticated and selected for elite racing ability over centuries. ERVs played an important role in the evolutionary diversification of the horse genome. In the present study, we identified six equine ERV families (EqERVs-E1, I1, M2, P1, S1, and Y4), their full-length viral open reading frames (ORFs), and elucidated their phylogenetic relationships. The divergence time of EqERV families assuming an evolutionary rate of 0.2%/Myr indicated that EqERV-S3 (75.4 million years ago; mya) on chromosome 10 is an old EqERV family and EqERV-P5 (1.2 Mya) on chromosome 12 is a young member. During the evolutionary diversification of horses, the EqERV-I family diverged 1.7 Mya to 38.7 Mya. Reverse transcription quantitative real-time PCR (RT-qPCR) amplification of EqERV pol genes showed greater expression in the cerebellum of the Jeju horse than the Thoroughbred horse. These results could contribute further dynamic studies for horse genome in relation to EqERV gene function.

Using the "Statistical Yearbooks of Korean forestry", we assessed the uptake of nitrogen and base cations by Korean forest. Combined amount of base cations uptake by forest tress during its growth and that of at the time of harvest reached to 1,034 eq/ha/yr. The base cations uptake in the range of 900 ~ 1,100 eq/ha/yr occupied approximately 48.6% out of total. Coniferous forest in the range of 170 ~ 200 eq/ha/yr was 59.9%, deciduous forest in the range of 430 ~ 530 eq/ha/yr was 42.6%, and mixed forest in the range of 270 ~ 370 eq/ha/yr was 35.7% out of total. Deciduous forest recorded higher uptake rate of nitrogen and base cation than coniferous forest in Korea. Combined amounts of nitrogen uptake by forest tress during growth and that at the time of forest, was 1,108 eq/ha/yr and nitrogen uptake was in the range of 1,000 ~ 1,200 eq/ha/yr, Within Korea, forest with nitrogen uptake in the range of 1,000 ~ 1,200 eq/ha/yr account for 45.7% of the entire country. Locations in the range of 320 ~ 390 eq/ha/yr occupied 43.9% of all coniferous forest while deciduous forest in the range of 470 ~ 570 eq/ha/yr was 40.4% of total deciduous forest. As for mixed forest in the range of 270 ~ 370 eq/ha/yr, it occupied 35.9% of all mixed forest of Korea.

Objectives The purpose of this study was to examine the daily lifestyle of Vietnamese immigrant women and to find out if they could affect health-related quality of life improvement. Methods The subjects of this study were 273 women who immigrated to Korea from Vietnam. This study was conducted at Daejeon and nearby Healthy Family Support Centers from September 2019 to January 2020 with the cooperation of the Daejeon City Healthy Family Support Center. Correlation analysis was performed between lifestyle and quality of life, and ANOVA analysis was performed to confirm the difference in health-related quality of life scores for each subgroup of dietary nutrition, sleep quality, and physical activity. A regression analysis was conducted to investigate the contribution of dietary nutrition, sleep quality, and physical activity to the quality of life of Vietnamese immigrant women. The significance level was p<0.05. Results Physical activity showed significant correlations with Euro Quality of Life -Visual Analogue Scale (EQ VAS), sleep quality with EQ VAS and Euro Quality of Life-5Dimension (EQ-5D) Index, and dietary nutrition with EQ-5D Index. There were significant differences in EQ VAS and EQ-5D Index scores for each sleep quality subgroup, and a significant difference in EQ VAS scores for each activity subgroup. The quality of sleep was found to have the greatest effect on EQ VAS and EQ Index of Vietnamese immigrant women, and physical activity on EQ VAS and dietary nutrition had some influence on EQ-5D Index. Conclusions Quality of sleep is closely related to health-related quality of life, and plays an important role in health-related quality of life for Vietnamese immigrant women.

This paper investigates different QA standards such as KEPIC QAP, KEPIC END 1200, ISO/1EC 17025 etc. and as a result defines QA elements for Nuclear Power Plant equipment qualification(EQ) in Korea. This paper also proposes a practical QA certification system appropriate for an Integrated Organization for EQ which is being planned to be established in Korea. Since the level of the Korean EQ technology is comparatively low, the Korean manufacturers of the Nuclear Power Plant(NPP) equipment have usually used overseas EQ services. The EQ related organizations in Korea are making efforts to construct the integrated EQ system. In connection with this, it is required that the QA elements and QA certification system suitable for EQ in Korea be developed.

음악은 수많은 악기가 내는 사운드로 구성되어 있다. 그 중에서도 사람의 목소리인 '보컬' 사운드는 그 어떤 악기보다도 가장 즉각적으로 잘 인지되는 파트이다. 곡에서 중요한 부분을 차지하는 보컬을 여러 사운드 속에서 완벽하게 믹싱하는 데에는 많은 요소들이 고려되어야 하고 또 다양한 단계들이 존재한다. 그 단계 중 EQ에 집중하여 연구하고자 한다. 따라서 본 논문에서는 EQ작업과 관련된 사항들에 대해 EQ의 개념 및 종류로 부터 시작해 보컬 레코딩 시 EQing방법, Subtractive EQ, Additive EQ 등에 관해 알아보도록 할 것이다. EQ는 사운드 믹싱 과정에서 특히나 보컬 사운드를 다루는데 있어서 가장 중요한 도구 중 하나로 손꼽힌다. 보컬 이큐잉은 보컬이 완벽히 트랙 믹스 안에 어우러지게 하기 위해 각 주파수 대역을 부스트 하고 또 컷팅하여 음색을 다듬는 과정이다. 프로페셔널한 보컬사운드를 얻기 위해서는 그 무엇보다도 자신이 스타일적으로 의도하는 사운드가 무엇인지 확실한 방향성을 가지고 가야하고 그를 위해 레퍼런스 트랙을 이용하는 것도 아주 효과적이다. EQing이외에도 컴프레션, 리버브, 코러스, 딜레이 등의 이펙터 작업과 백킹 보컬과 하모니의 조정 등의 다양한 복잡한 단계의 작업이 있고 그 또한 매우 중요한 작업들이다. 그러나 믹싱의 시작에 해당하는 작업인 EQing은 무엇보다도 그 중요도가 큰 관계로 위 사항들을 두루 고려하여 세밀한 작업을 하여야 할 것이다.

Purpose: The purpose of this study is to identify levels of quality of health-related life (EQ-5D) and its related factors among vulnerable elders receiving home visiting health care services in some rural areas. Methods: The subjects of this study were vulnerable elders aged 65 or higher receiving visiting health care benefits by a public health center in a county. Results: Levels of health-related EQ-5D were high when the subjects were males, their ADL and IADL were high. The EQ-5D of the vulnerable elders and social supports had a positive correlation, while their IADL and depression had a negative correlation with the EQ-5D. We can see that the EQ-5D related factors are variables that have significance influence on gender, subjective health status, BMI, IADL, depression levels, and social support. Conclusion: To improve the EQ-5D of the vulnerable elderly, it needs maintenance of independent IADL levels, social supporting systems using small meeting of the elderly in community. It is necessary to maintain independent IADL levels, enhance social supporting systems including small group gatherings for elders living alone by means of places like community halls, and develop specific intervention programs for the prevention and management of depressive elders.

Stomach cancer shows the highest incidence among cancer patients in Korea and it deteriorates the patients' health-related quality of life considerably. This study measured utility weights of severe stomach cancer symptoms using VAS (Visual Analogue Scale), TTO (Time-trade Off) and EQ-5D (EuroQol-5 Dimension) methods. A survey questionnaire was developed to describe the symptoms of severe stomach cancer comprehensively and concisely using VAS, TTO and EQ-5D. A face-to-face interview was conducted for 21 cancer inpatients in a hospital and 25 non-patients. The mean utility weight is 0.498 for VAS, 0.375 for EQ-5D and 0.300 for TTO. Using VAS or TTO methods, there were no statistically significant differences between patients and non-patients while there was significant difference in EQ-5D. The utility weight with VAS and EQ-5D has shown similar trend - higher score in patient group, male and aged while it has opposite trend with TTO.
