RNA-mediated regulation of chromatin structures

Youngtae Kwon,Yun Doo Chung 한국유전학회 2020 Genes & Genomics Vol.42 No.6

It is now evident that transcriptional gene regulation usually requires the re-organization of chromatin architecture. Increasing evidence suggested various kinds of RNAs are involved in this process. Especially the nascent RNAs retained at their site of transcription can serve as a scaffold for organizing transcriptionally either favorable or unfavorable chromatin structures. An emerging concept of phase separation explains how these chromatin structures can be maintained as physically discrete subcompartments within membrane-less nucleoplasm. Evidences that support the crucial role of nascent RNAs in the formation of phase-separated condensates are now rapidly growing.

In order to prevent cones from being damaged by cone insects, Gravitarmata margarotana and Dioryctria abietella, sprinkler system was installed on the Pinus koraiensis Seed Orchard. Such a test was conducted at Chung-ju, Chungcheong buk-do, Korea in 2002. Insectides of Diflubenzuron 25% WP ×2500 and Cyfluthrin 2%EC ×1000 were sprayed at fifteen-day and twenty-day intervals during the period of insects adult occurrence by sprinkler system. The Gravitarmata margarotana generally emerged for about 53 days from middle April to early June, and peak emergence was 10 days from April 20 to April 30. Dioryctria abietella generally emerged for about 108 days from late April to early August, and peak emergence was 10 days from May 20 to May 30. Damage rate of cones were 8.7~9.7% and 10.9~12.7% on average with crown insecticide spraying with Cyfluthrin and Diflubenzuron, while 67.5% when not treated. Control effectiveness of this insecticide spraying was 85.6~87.1% and 83.9%와 81.2%, respectively. When it considers the forest environment, it is recommended diflubenzuron which is low toxic pesticide. In conclusion, effectual times and number of diflubenzuron 25% WP application with sprinkler system against cone insects were from early May through late August and six times at twenty-day interval.

정청희,권태엽 한국스포츠심리학회 1992 한국스포츠심리학회지 Vol.3 No.1

본 연구의 목적은 경쟁결과와 성별이 원인지각에 미치는 영향을 검증하는 것이다. 연구를 위한 검사도구는 McAuley등이 1989년에 개발한 원인차원척도 질문지를 우리 설정에 맞게 번안한 후 타당성과 신뢰도를 검증하여 사용하였다. 연구 대상은 중학교 3학년에 재학중인 남자 28명과, 여자 20명으로 총 48명이다. 피험자들은 체육수업의 마지막 단계에서 체육교사에 의하여 배드민턴 기능 평가를 받았으며 성적편차 4점을 기준으로 능력별 대진표를 작성하였다. 작성된 대진표에 따라 피험자들은 서울대학교 체육관에서 배드민턴 경기를 하였고, 경기가 끝나는 즉시 승자와 패자로 분류하여 질문지에 반응하도록 하였다. 자료분석은 이원변량 분석의 통게기법으로 하였다. 연구결과는 다음과 같다. 첫째, 경쟁결과에 따라 내재성, 안정성, 외적 통제가능성, 내적 통제가능성의 원인지각 차원에 유의한 차이가 있었다. 즉, 승자는 패자에 비하여 자신의 결과를 내적이고 안정적인 것으로 원인지각 하였다. 그리고 외적 통제가능하고 내적 통제가능한 것으로 원인지각 하였다. 둘째, 성별에 따라 외적 통제가능성, 내적 통제가능성의 원인지각 차원에 유의한 차이가 있었다. 즉, 남자는 여자에 비하여 자신의 결과를 외적 통제불가능하고, 내적 통제가능한 것으로 원인지각 하였다. 셋째, 경쟁결과와 성별에 따라 외적 통제가능성의 원인지각 차원에서 상호작용 효과가 유의한 것으로 나타났다. The purpose of this study was designed to apply the causal dimension scale Ⅱ in a competitive sport setting and to examine differences competitive outcome and sex upon their causal attributions about performance. The subject of this study were 48 male and female in the middle school student. Of particular, interest are the causal attributions made by participants tested badminton in physical education class. With meet Director is permission, the investigator briefly explained the study to all the players at the beginning of the game, stating that the study concerned subject's causal perception of their competitive outcome. Upon completion of the game, subjects were asked to assess their competitive outcome in terms of the causal dimensions of internality, stability, external controllability and internal controllability using the CDS Ⅱ. Two-way analysis of variance were conducted to determine whether the differences in causal attribution existed between 1) winners and losers, 2) male and female. The results obtained from this study were as follows 1. Winners made more internal, stable, external controllable and internal controllable causal attributions than losers on their competitive outcome. 2. Male and female did not differ in the internality, stability of their causal dimensions. Male made more external uncontrollable, internal controllable causal attributions than female on their competitive outcome.

Objective: The purpose of this study was to evaluate clinical efficacy of fetal fibronectin as a marker to predictor of preterm labor. Materials & Methods: The study group consisted of sixty-eight healthy pregnant women, at gestational age between 24 and 36 weeks, who visited our department with vaginal discharge from April, 1995 to December, 1997. For comparison, we divided all of the pregnant women into two groups by the result of ROM-Check^®, positive groups(N=21) and negative groups(N=47). When preterm labor appeared, 50mg of ritodrine hydrochloride(Yutopar^®) mixed I liter of 5% dextrose solution was administered slowly intravenously. Results: 1) The gestational age at delivery and the interval time from admission to delivery in the positive groups were significantly shorter than those of the negative groups(p<0.05). 2) The positive groups had significantly lower birth weight and Apgar scores than the negative groups(p<0.05). 3) Among the negative groups, in case of tocolytics administration, the interval time from admission to delivery significantly delayed more than that time in case of no tocolytics administration(p<0.05). Conclusions: The detection of the fetal fibronectin in vaginal discharge had a useful method as a predictor of preterm labor. Tocolytics was more effective in the negative groups than in the positive groups.

In the present study, an effort was directed to elucidate the effect of the physical training on the pulmonary function. Nine male athletics major student who have undergone regular physical training for more than five years were randomly chosen as the athletic subjects, and 9 regular male students who have not been engaged in any form of regular physiycal exercise or training were chosen as the non-athletic subjects, and a comparison was made between the two groups. The following were mainly observed by spirometry for the study respiratory rate, tidal volume, vital capacity, maximun voluntary ventilation (MVV), forced expiratory volume for 1 second (FEY, ), percent FEV, to forced vital capacty (FEV 1%), forced expiratory flow for initial 1 liter (FEF 0.2-1.2L), and forced mid-expiratory flow (FEF 25-75%) The results obtained are summarized as follow; 1) The respiratory rate, and tidal volume showed no significant difference between athletes and non-athletes. The VC and MVV in non-athletes was significantly (p< 0.05, p <0.01)increased to 5.552±0.138L, 158.2±3.11L/min comparing with 4.770±0.2444L, 128.3±9.1L/min in non-athletes. 2) FEV, was 4.781±0.193L in athletes and 4.249±0.136L in non-athletes ; FEV 1% 84.12±1.12% in athletes and 73.45±1.79% in non-athletes, both was significantly (p < 0.05)increased in athletes. 3) FEF0.2-1.2L/min was 296.4±11.7L/min in athletes and 227.7±14.5L in non-athletes ; FEF 25-75% was 3.673±0.119L/sec inathletes and 2.810±0.178L/sec in non-athletes, both showing significant(p<0.05) increase in athletes. 4) Some liscussions were made on these results. The lung volumes showed no significant difference between the two groups, but VC, MVV, FEV1, FEV, %, FEFO.2-1.2L and FEF25-75% in athletes were significantly (p<0.05, p<0.01, p< 0.05, p<0.05, p<0.05, p< 0.05 respectively)higher than in non-athletes. It is therefore concluded that the athletes have more powerful respiratory muscles, or higher compliance of the lung and thorax than the non-athletes.
