Colored apiculus, awn, and long empty glume are indicators of wildness and are usually eliminated during rice domestication. Genetic analysis was conducted to clarify the inheritance patterns of awn, apiculus color, and long empty glume in Korean rice collection. Based on individual characterization of F$_2$ progenies derived from crosses between parents with colorless and purple apiculus, two (3 colored: 1 colorless) or three dominant genes (9 purple: 3 red: 4 colorless) are estimated as controlling this character by simultaneous complementary action. Different inheritance systems were detected between S237 and S245 of 'Shareibyeo' which belong to the weedy type. To determine the genes responsible in awning and long empty glume characters, the inheritance of landrace varieties of rice ('Naengdo' and 'Yuna') was investigated. In the crosses of awned land race and awnless cultivar, three dominant genes are supposed to control the awning genetic system by 63 awned: 1 awnless individual. As for long empty glume, one recessive gene, g-l on the chromosome 4, was the one controlling the segregation ratio of 3 normal empty: 1 long empty glume. By analyzing the Korean rice collection, the inheritance systems of these wild characters may lead to a better understanding of rice domestication in the future.

The purpose of this study was to Investigate men's clothing in regard to (1) the effect of wearer's age and clothing: rues on impression formation, and (2) the effect of perceiver's age on impressions formed by the wearer's age and the fuction of clothing cues. The experimental design of this study was between-subjects 24_full factorial design by 4 independent variables. The subjects consisted of 192 subjects in each of two male perceiver groups according to age(20s and 50s). The experimental moterials developed for the study were a set of stimuli al)d a response scale. The stimuli consisted of 16 color photographs made by identical manipulations of 4 independent variables consisting of 2 levels each. Each one of the sixteen sub-samples included 12 subjects from 2 perceiver groups. The independent variables provided by the photographs were (1) wearer's age (20s and 50s), (2) suit color (navy blue and beige),' (3) suit style (single breasted and double breasted), and (4) necktie color (analogous and complementary colors) . The 7-point semantic differential response scale which was designed to measure the impression of the stimuli was composed of 30 bipolar adjectives. The responses to the semantic differential scales were analyzed using factor analysis and ANOVA. The results were as follows:1) Wearer's age, suit color, suit style, and necktie color had significant effects on impression of the 3 factors (appearance·potency, individuality activity, and evaluation) partiafly. However, the suit style was the most dominent clothing cue : the single breasted suit conveyed positive impression of individuality' activity to both of the wearer's age groups than double breasted suit did on both of the perceiver's age groups. 2) Perceiver's age partially influenced impressions formed by the age and the clothing cues of men clothed in suits : the young perceiver's group was less affected by them than middle aged group.

본 논문은 3차원 공간상에서 행해지는 수신호들을 인식하는 시스템을 다룬다. 수신호 입력을 위한 장치로는 두 대의 컬러카메라를 사용한다. 비전에 기반을 둔 제스처 인식 방식은 그 자체의 비접촉식 특성으로 인해 사용자 편의 면에서 우수한 것으로 알려져 있다. 그러나 여타의 카메라를 입력 장치로 사용하는 방식들이 그러하듯이 배경과 조명 변화에 대해 취약하다는 것이 문제시된다. 본 논문에서는 특수한 장갑이나 표식을 사용하지 않고도, 배경 및 조명 변화에 강인하게 입력 영상에서 손영역을 검출하기 위해, 적응 손 컬러 모델과 함께 이전 위치 정보를 이용하였다. 손 영역 영상으로부터 수신호를 인식하기 위해서, 본 논문은 '손 자세'와 '손 궤적'을 기본요소로 하는 수신호 정의 방식을 바탕으로 한다. 확장성 있는 손 자세 분류를 위해서 소그룹 개념을 통한 2단계의 분류방식을 제안한다. 3차원 수신호 영상을 얻기 위해 사용된 두 대의 카메라로부터 얻은 영상들에 대한 상호보완적 선택 방법도 제시한다. 제안된 수신호 인식 방법은 차량 주행 시뮬레이터에 적용하여 실제 환경에서의 적용 가능성을 검증하였다.

벼 자색 종자과피(Purple pericarp, Prp) 형질은 주요 생리활성물질인 안토시아닌 C3G 생성에 관여하며 흑미를 결정하는 주요 유전형질이다. Prp 유전형질을 가진 흑미와 종자과피에 색이 없는 벼를 교배할 경우 그 후대는 검정색, 갈색, 백색이 각각 9:3:4로 분리된다. 1921년 Nagai에 의하여 제시된 바 벼 종자 색의 9:3:4 유전분리비로 인하여 벼 Prp 형질은 유전자의 열성상위(recessive epistasis) 현상으로 해석되었다. 그러나 흑미를 결정하는 Prp 형질은 두 개의 상보적 유전자들의 상호관계(complementary gene interaction)에 의한 것이기도 하다. 본 연구에서는 이러한 논란이 발생되는 이유를 설명하기 위하여 두 유전자의 조성이 완전한 이형접합인 Pbpb Pppp 유전자형을 가진 $F_1$ 잡종을 만들었다. 이들의 자손은 진한자색(검정), 중간자색, 갈색, 백색 종자이며 각각 3:6:3:4로 분리되었다. 즉, 검정색, 갈색, 백색의 종자가 각각 9:3:4의 비율로 분리된다. 그러나 생화학적인 분석결과 이들은 안토시아닌 중 cyanidin 3-O-glucoside (C3G)가 축적된 검정색 종자와 C3G가 없는 갈색 또는 백색 종자인 두 개의 집단을 분리되며 정확히 9:7의 분리 비를 갖는다. 이 경우 벼 Prp 형질을 갖는 검정쌀 또는 흑미는 전형적인 상보적 유전자의 상호관계에 의한 유전현상이다. 즉, 흑미의 자색 종피 형질 발현에는 Pb 유전자와 Pp 유전자에서 각각 한 개 이상의 우성대립인자의 발현이 필요하다. 그러나 Pb 유전자만 우성대립인자가 존재하는 Pb_ pppp 유전자형의 벼는 C3G를 생성하지 못하고 갈색 종자과피(Brown pericarp, Brp) 형질을 갖게 된다. 즉 갈색쌀는 우성 Pb 유전자의 우성대립인자에 의하여 결정된다. 그러므로 종피색을 결정하는 Prp 형질의 유전양상은 열성상위 현상으로 보이나 흑미의 결정요소인 안토시아닌 C3G의 함유 여부에 관한 유전분석을 시행하면 9:7의 비율로서 전형적인 두 개의 유전자가 모두 관여하는 상보적 유전현상이다. 유전적 정의는 유전자의 최종산물에 의한 물리적 또는 화학적 결정이다. 그러므로 결론하여 검정 쌀의 주요 생리활성물질인 안토시아닌 C3G 생성에 관한 유전현상은 Pb와 Pp 유전자의 상보적 유전자의 상호에 의한 것이다.

Northeastward drifts of massive Sargassum patches were observed in the East China Sea (ECS) and Yellow Sea (YS) by the Geostationary Ocean Color Imager (GOCI) in May 2017. Coverage of the brown macroalgae patches was the largest ever recorded in the ECS and YS. Three-dimensional circulation modeling and Lagrangian particle tracking simulations were conducted to reproduce drifting trajectories of the macroalgae patches. The trajectories of the macroalgae patches were controlled by winds as well as surface currents. A windage (leeway) factor of 1% was chosen based on sensitivity simulations. Southerly winds in May 2017 contributed to farther northward intrusion of the brown macroalgae into the YS. Although satellite observation and numerical modeling have their own limitations and associated uncertainties, the two methods can be combined to find the best estimate of Sargassum patch trajectories. When satellites were unable to capture all patches because of clouds and sea fog in the ECS and YS, the Lagrangian particle tracking model helped to track and restore the missing patches in satellite images. This study suggests that satellite monitoring and numerical modeling are complementary to ensure accurate tracking of macroalgae patches in the ECS and YS.

Mutation breeding is useful for improving agronomic characteristics of various crops. In this study, we constructed soybean Mutant Diversity Pool (MDP) from 1,695 gamma-irradiated mutants through two selection phases over M1 to M12 generations; we selected 523 mutant lines exhibiting at least 30% superior agricultural characteristics, and, second, we eliminated redundant morphological phenotypes in the M12 generation. Finally, we constructed 208 MDP lines and investigated 11 agronomic traits. We then assessed the genetic diversity and inter-relationships of these MDP lines using target region amplification polymorphism (TRAP) markers. Among the different TRAP primer combinations, polymorphism levels and PIC values averaged 59.71% and 0.15, respectively. Dendrogram and population structure analyses divided the MDP lines into four major groups. According to an analysis of AMOVA, the percentage of inter-population variation among mutants was 11.320 (20.6%), whereas mutant inter-population variation ranged from 0.231 (0.4%) to 14.324 (26.1%). Overall, the genetic similarity of each cultivar and its mutants were higher than within other mutant populations. In an analysis of the genome-wide association study (GWAS) using based on the genotyping-by-sequencing (GBS), we detected 66 SNPs located on 13 different chromosomes were found to be highly associated with four agronomic traits: days of flowering (33 SNPs), flower color (16 SNPs), node number (6 SNPs), and seed coat color (11 SNPs). These results are consistent with those previously reported for other genetic resource populations, including natural accessions and recombinant inbred line. Our observations suggest that genomic changes in mutant individuals induced by gamma rays occurred at the same loci as those of natural soybean population. This study has demonstrated that the integration of GBS and GWAS can serve as a powerful complementary approach to gamma-ray mutation for the dissection of complex traits in soybean.
