Rice grain shape is one of the key components of grain yield and market value. An understanding of the genetic basis of the variation in grain shape could be used to improve grain shape. In this study, we developed a total of 265 F₂ individuals derived from a cross between japonica cultivars (Josaeng-jado and Langi) and used this population for quantitative trait locus (QLT) analysis. Correlation analysis was performed to identify relationships between grain traits (GL: grain length, GW: grain width, L/W: ratio of length to width, TGW: 1,000 grain weight). The grain shape was positively correlated with GL and TGW, and negatively correlated with GW. In QTL analysis associated with grain shape, one QTL for GL, qGL5, detected on chromosome 5, explained 20.3% of the phenotypic variation (PV), while two QTLs, qGW5 (PV=36.1) and qGW7 (PV=26.1), for GW were identified on chromosomes 5 and 7, respectively. Evaluation of the effects of each of the QTLs on the grain shape in the population showed a significant difference in the grain size in positive lines compared with the lines without the QTLs. According to the QTL combination of the allelic-types, the grain shape of the tested lines varied from semi-round type to long spindle-shaped type. The results of this study extend our knowledge about the genetic pool governing the diversity of grain shape in japonica cultivars and could be used to improve the grain shape of this species through marker-assisted selective breeding in Korea.

Objectives:Rapid eye movement(REM) sleep behavior disorder(RBD) is a parasomnia characterized by loss of normal atonia during REM sleep and dream enacting behavior(DEB) including vocalizations, striking behaviors or violent movements. A proportion of RBD patients had showed mild cognitive decline, but it is controversial. This study has an aim to compare neurocognitive functions between idiopathic RBD(iRBD) and normal subjects in the Korean elderly. Methods:Twenty-six iRBD subjects and 25 normal controls were selected by polysomnography, brain magnetic resonance imaging and clinical interview with psychiatrist. All the subjects completed the Korean version of the consortium to establish a registry for Alzheimer’s disease neuropsychological battery(CERAD-KN) as an objective cognitive measure and subjective memory complaints questionnaire(SMCQ). Additionally Pittsburgh sleep quality index (PSQI) for sleep quality, the Epworth sleepiness scale(ESS) for daytime sleepiness and the Korean version of the geriatric depression scale(GDS) for depressive symptoms were done. Results:iRBD subjects showed poorer sleep quality with PSQI than normal controls, but there were no differences in other sleep parameters between groups. In the neurocognitive function test, iRBD subjects showed higher SMCQ score and lower score of Digit span backward test than normal controls. Conclusion:In the elderly, subjects with iRBD had subjective memory complaints and impaired attention function, but not other objective cognitive measures. As attention function as well as subjective memory complaints might an indicator for cognitive disorders, iRBD patients with mild cognitive decline needs to be adequately controlled.

이 논문은 봉산탈춤의 창작과정을 다루고 있다. 논문은 전체 6장으로 구성되어 있는데 제1장에서 창작탈춤의 교육은 가능한가라는 질문을 제기한다. 이어서 한국예술종합학교 연극원에서 개설한 <전통연희의 무대적 수용>이라는 실습과목을 소개하였다. 전체 과정을 강의, 특강 18시간, 탈춤강습 12시간, 연구와 토론 6시간, 장면발표 12시간 등 총 48시간 동안의 케이스 스터디를 소개하고 있다. 탈춤의 구성요소로, 말, 탈, 춤, 판, 흥, 다섯 가지 요소를 제시하였는데, 탈춤이나 전통연희를 잘 모르는 대학생들이나 일반인들에게 전통탈춤을 쉽게 접근하기 위한 방법을 소개하고 있다. 이런 다섯 가지 요소를 가지고 탈춤의 구성요소를 하나의 문장으로 만들면, “말을 타고 춤판에서 흥을 내자”로 요약할 수 있다. 간결한 캐치프레이즈로 탈춤의 구성요소를 파악하고 있다. 이어서 봉산탈춤의 세가지 매력으로 불림, 등퇴장양상, 연풍대 춤을 설명하는데 이 부분이 이 논문의 핵심이라고 할만하다. 탈춤의 연극미학적 특징을 불림과 등퇴장의 기능에서 찾고 있다. 불림이란 장단이나 음악반주를 청하는 외침이지만 등장인물은 불림을 통해서 행동의 목적을 드러내고 있다고 본 것이다. 등퇴장 양상은 각 장면의 시작과 끝을 장식하는 대목으로써 장면구분을 통해서 구성의 기능을 나타낸다고 보았다. 드라마에서 가장 중요한 등장인물의 행동과 구성을 불림과 등퇴장 양상으로 파악하고 분석하고 있다. 결론에서는 메르치아 엘리아데의 ‘환상적 실재’의 개념을 빌려서 전통연희의 현대적 수용에서 형식에 그치는 모방적 수용이 아닌 창조적 수용의 가능성과 경계해야할 형식적 입장을 지적하고 있다. 봉산탈춤의 현재적 수용이라는 명제아래 봉산탈춤의 창작적 요소를 명쾌하게 분석하여 이를 매개로한 창작과정의 실례를 케이스 스터디로 보여 주고 있다. This article discusses the creative process of Bong San Tal Chum. [Bong San Mask Danced Drama] This paper consists of six chapters. Chapter 1 raises a question about whether the creative process might be possible to transform the traditional art forms into the contemporary performance. The author explains his personal but academic experiences when he have taught the subject of <전통연희의 무대적 수용, The Stage Adaptation of Traditional Performance> at the School of Drama, Korean National University of Arts. Chapter 2 deals with the 5 plot elements as words, mask, dance, pan[stage], and heung [a hyped feeling]. Traditional performance, such as Bong San Tal Chum, is not familiar one among most of young generation. So, the author has created a sentence form the above five elements. “Let"s Ride a Horse with Heung in Chum Pan.” Next two chapters deal three attractives form Bong San Tal Chum and their dramatic functions. Those three are Bulrim[불림], Style of entrances and exits, Yeoun Pong Dae[연풍대, one of the dance expression]. Bulrim and the style of entrances and exits of each characters make this Mask Danced Drama so unique and very theatrical. Bulrim tells audience each characters" action and their purpose of entrance. The Style of entrances and exits form various characters helps audience to understand the plot structure. In the conclusion, the author borrows a concept of "fantastic reality" what Mircia Eliade (1907-1986) used to criticise the lifeless adaptation of Rumanian performance form its traditional arts form and emphasizes the importance of the spiritual recreation of the performance environment from the past.

PURPOSE: Focusing on the factors that influence the infectious disease emergency response policy (approached by dividing the factors into health policy management and economic policies), both SARS and MERS cases were based on the legal system, manpower, and budget, but there has not been enough learning from the epidemic. This study focused on infectious disease emergency governance, which various studies have neglected despite its social and academic importance. METHODS: The research is based on an analysis of SARS, MERS, and COVID-19 and compares global policies. In this study, infectious disease emergency governance was divided into health policy management and economic factors. This study focused on planning and leadership before and after the outbreak of infectious diseases and how cooperation was achieved to monitor and respond to infectious diseases successfully. RESULTS and CONCLUSION: The limit of this study was that COVID-19 is a currently ongoing infectious disease with high uncertainty. Because it is an ongoing problem, only some data and statistics are reflected, and many limitations prevent a proper comparison under the same criteria as other infectious diseases. In addition, because continuous changes are expected, there is also room for infectious diseases to develop in a completely different pattern from the current situation, and continuous research must be accompanied in the future.

Korea faced an unprecedented crisis in infectious disease management system as the number of confirmed cases of COVID-19 in Korea soared in March 2020. It was difficult not only for the confirmed patients but also for the seriously ill patients to be assigned beds, so the Residential Treatment Centers were introduced under the concept of isolating and treating asymptomatic or mild patients without treating them in hospitals or self-isolation. In this study, we examined user analysis, legal basis, and operational problems, focusing on the operation of the Gyeonggi International 2 Residential Treatment Center (hereinafter referred to as Ansan Residential Center), which quarantined and treated people diagnosed with COVID-19 from overseas. From March 26 to May 13, 2020, for 49 days, 115 confirmed patients with “COVID-19” who were hospitalized at Ansan Residential Treatment Center were analyzed for their general characteristics and medical records including length of stay and treatment results. Major results showed that 56 people were diagnosed with complete recovery in the Residential Treatment Center, 26 were moved to other Residential Treatment Centers on demand and 28 were taken to other hospitals due to worsening health conditions. The operational problems of Ansan Residential Treatment Center were the lack of operating principles, a lack of skilled medical personnel, a long-term delay in payment of allowances for working applicants and a lack of medical video-related facilities. Through this study, we found that Residential Treatment Center can be a positive factor that prevents the spread of COVID-19 in Korea, but we raise the need to comprehensively analyze the performance of the treatment in Residential Treatment Centers at the national level.

Objective : Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) is known to reduce the quality of sleep and is associated with various psychiatric disorders. The aim of this study was to investigate the relationship of PMS with depression, sleep qulity and sleep pattern in Korean female adolescents. Methods : Out of 867 high school female students, 400 female subjects were included in this study. All participants completed self-report questionnaires that included demographic variables, shortened premenstrual assessment form (SPAF), patient health questionnaire-9 (PHQ-9), Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), insomnia severity index (ISI) and Korean translation of composite scale (CS). A total of 394 individuals who completed the questionnaires were analyzed. Results : As score of SPAF, 143 subjects was defined PMDD group. They had more prevalence of eveningness, more depressive symptom, poorer sleep quality, and more excessive sleepiness than non-PMDD groups. Although the PMDD groups showed more menstrual dysmenorrhea, no difference was found in bleeding duration and cycle. PMS symptom had correlations with depression, poorer sleep quality and excessive sleepiness during the daytime. There was no difference in sleep duration between two groups, but PMS might have a relationship with eveningness of chronotype. Conclusions : Among Korean female high school students, the PMS might have an association with depression and poor sleep quality, and it might lead to daytime impairment due to excessive sleepiness. An appropriate evaluation of PMS could be helpful in determining the mental health condition of adolescents.

Early maturing rice is widely utilized to diversify cropping systems in the Honam Plain, Korea. It is based on the principle ofa short growth duration. There is concern regarding quality deterioration of early maturing rice owing to the high temperature during theripening stage as compared to that for mid and mid-late maturing rice. This study was conducted to analyze six pasting property-related andeight quality traits of six early maturing rice varieties (Jopyeong, Odae, Unkwang, Haedamssal, Jinkwang, and Haedeul) on early, ordinary,and late cultivations, and to interpret the relationships between genotypes and environments. As the cultivation time increased, the ratio ofhead rice (HR) and glossiness of cooked rice (Toyo value, TY) increased. The cumulative mean temperature of the ripening stage showeda strong negative correlation with HR and TY at all cultivation times. Pasting temperature, peak viscosity (PV), trough viscosity, final viscosity,and breakdown (BD) decreased, whereas setback (SB) increased as the cultivation time was delayed. Pasting properties were affected moreby climate conditions in the ripening stage than during the growth stage. Additive main effects and multiplicative interaction analysis revealedthat pasting property-related and quality traits were affected more by environment than genotype. Jinkwang and Haedamssal in early and ordinarycultivation and Jinkwang and Haedeul in late cultivation exhibited higher HR and TY and a lower protein content. They also showed higherPV and BD and lower SB, which are characteristics of good eating quality japonica rice. Jinkwang, Haedamssal, and Haedeul are premium-quality,early maturing rice varieties that were recently developed. The cultivation of these varieties could improve the grain quality of early maturingrice at high temperatures during the ripening stage in the Honam Plain.

‘Jonong’ is an early maturing whole crop silage (WCS) japonica rice cultivar characterized by a short growth duration and numerousspikelets. It was developed to enhance the adaptability of WCS rice to double-cropping systems. ‘Jonong’ is derived from a cross between‘Binhae Col.#1’ and ‘Deuraechan’; ‘Binhae Col.#1’ is a semi-early maturing China rice germplasm with numerous spikelets on dense panicles,whereas ‘Deuraechan’ is a high-yielding japonica rice cultivar with numerous spikelets on long panicles. To diversify the genetic variationand shorten the breeding period, an anther culture method was applied to the F₁ plants. ‘Jonong’ was selected through the pedigree method,yield trials, and local adaptability tests, with a high selection pressure for short growth duration and high biomass. The average heading dateof ‘Jonong’ was August 1st, which is 11 days earlier than that of ‘Nokyang’, the standard cultivar for WCS rice. Moreover, the growth durationof ‘Jonong’ is the shortest among all Korean WCS rice cultivars. The culm length of ‘Jonong’ is 88 cm, which 4 cm longer than that of‘Nokyang’ and the highest among all Korean early maturing rice cultivars. ‘Jonong’ has 149 spikelets per panicle, which is 30 more thanthat of ‘Nokyang’, and is the highest among all Korean early maturing rice cultivars. ‘Jonong’ exhibits stable premature heading and is tolerantto lodging. It is moderately resistant to leaf blast and resistant to the rice stripe virus. The feed value of ‘Jonong’ in terms of total digestiblenutrients is good and comparable to that of ‘Nokyang’. Furthermore, compared with ‘Nokyang’, ‘Jonong’ shows a similar level of dry matteryield and a higher rough rice yield. Therefore, ‘Jonong’, an early maturing WCS japonica rice with short growth duration and numerousspikelets, would be suitable for cultivating in winter forage crop-rice double cropping systems (Registration No. 7274).

Interspecific and intersubspecific crosses have been an important strategy for rice breeding programs to obtain useful charactersby expanding genetic diversity. However, the wide cross routinely causes undesirable characters in rice, such as spikelet sterility and poorquality. In this study, we developed near-isogenic lines of R-gene (Xa4+xa5+Xa21+Pi40+Bph18) introgression population to investigate thegenetic relationship between the occurrence of poor characters and R-genes induced by MAS. The ANOVA analysis revealed that Pi40, Bph18,and Xa4 were associated with spikelet fertility (SF), ratio of ripened grain (RRG), third internode length (TIL), panicle extraction (PE), andprotein content (Pro), whereas others showed no association with the 14 traits tested. In the three-way ANOVA, the impact of two R-genes(Pi40 and Bph18) on the poor characters was independent, with no interaction with others. Quantitative trait locus (QTL) analysis identifiedQTLs for PE and TIL traits near Pi40, and in particular, QTLs for five traits (SF, RRG, TIL, PE, and Pro) were negatively affected aroundBph18. The occurrence of a poor character in R-gene pyramiding lines could be associated with linkage drag caused by the Bph18 gene. We speculate that the development of DNA markers that effectively eliminate poor characters will not only improve breeding efficiency usingMAS, but will also help improve traits of japonica rice through wide crossing.
