  • The young casual wear market has been recently increased by the great buying power of the target consumers, although they don't have their own discretionary income. The purpose of this study was to investigate clothing attitudes of the adolescent consumers of the young casual wear market according to the groups of personality types. The questions on introversion/extroversion of MBTI test were adopted to measure introversion/extroversion in personal characteristics. The questions in "The personality diagnosis of high school students" developed by Lee, Chongseung and Chung, Bummo were adopted to measure stability, dominance, sociability and autonomy. Variables of clothing attitudes were composed with attentiveness, modesty and conformity. A total 488 high school students in Seoul participated in the survey. SPSS Win 10 statistical package was used to analyze the data: frequency, t-test, ANOVA and factor analysis. After statistical analysis, the following results were found. Groups of introversion and extroversion, and groups of low, medium and high degree of stability, dominance, sociability and autonomy showed no significant difference based on sex difference and school types. Students who has a high extroversion showed a high degree of attentiveness in clothing attitudes. Students who has the lowest sociability and the lowest autonomy showed a high degree of attentiveness. Students with the lowest autonomy showed a high degree of conformity. The younger the students were, the higher their attentiveness and modesty in clothing attitudes.

  • The plant communities of the eastern ridge in Mt. Cheonma, Central Korea, Quercus mongolica, Q mongolica-Acer pseudo-sieboldianum, and Q. mongolica-Rhododendron schlippenbachii communities in the northern slope and Q. variabilis and Q. cutissima communities in the southern slope were detected by Zurich-Montpellier method. The undergrowth of Q mongolica community in the northern slope was dominated by Ainsliaea acerifolia, Carex siderosticta, Astilbe chinensis var. davidii, Heloniopsis orientalis, Pseudostellaria palibiniana, ranging 3.3 to 2.2 in dominance-sociability, while the those of Q variabilis and Q acutissima in the southern slope were dominated by Spodiopogon cotulifer, Artemisia keiskeana, Carex humilis, Atractylodes japonica, Lysimachia clethroides and Disporum smilacinum with similar degree in dominance-sociability to that of Q mongolica community. The two communities were considered as regenerating forest after severe disturbance judging by their age structure. The relationship between Shannon's diversity index (H') and Simpson's dominance index (i) was in reciprocal proportion in both two communities. The Q. mongolica and Q. variabilis communities were showed 13 and 12 m respectively. Seasonal changes of undergrowth coverage in the two communities were seemed to be affected especially with soil moisture among environmental factors such as temperature, light intensity, relative humidity and organic matter.

  • This study was carried out to get the genetic information on the germination rate and fat acidity after 12 weeks' storage at $35^{\circ}C$. Germination rate decreased with longer storage period, while fat acidity increased. Germination rate was higher in the order of Koshihikari, Hanmaeum and Unkwangbyeo after 12 weeks' storage at $35^{\circ}C$. Fat acidity of Koshihikari and Hanmaeum was gradually increased, but that of Unkwangbyeo was dramatically increased after 4 weeks' storage at $35^{\circ}C$. The genetic mode on germination rate and fat acidity using the joint scaling test was shown to be additive-dominance gene effects. Additive([d]) effect was higher than dominance effect([h]) in all crosses. The average degree of dominance, [h]/[d], was less than 1, indicating that germination rate and fat acidity was partially dominant. Germination rate and fat acidity based on frequency distribution of 2 crosses were quantitative characters expressed by polygenes.

  • The present study was undertaken in middle altitudinal (1500 to 2500 masl) moist temperate forest of Mandal-Chopta area in the Garhwal region of Uttarakhand, India. The aim of the present study was to assess the variation in species composition and diversity in different vegetation layers viz. herb, shrub and tree, at different altitudes. Shannon-Wiener diversity index ($\bar{H}$), $Nha^{-1}$, total basal cover per hectare (G), Simpson concentration of dominance, Pielou Equitability, species richness (SR), Margalef index, Menheink index of species richness and ${\beta}$-diversity were calculated to understand community composition. Tree G ranged from 84.25 to 35.08 $m^2ha^{-1}$ and total stem density varied from 990 to 1470 Nha-1. Total SR (herb, shrub and trees) among different forest types ranged between 31 and 58. Maximum G of herb and shrub layers was recorded at lower altitudes between 1500 and 1650 masl. ${\beta}$-diversity was higher in herb layers as compared to tree and shrub layers. Dominance-diversity curves were also drawn to ascertain resource apportionment among various species in different forest types. Values of species diversity, $\bar{H}$, $Nha^{-1}$ and G were higher in the study area as compared to similar forests growing in other parts of Uttarakhand Himalaya.

  • Habitat-forming species increase spatial complexity and alter local environmental conditions, often facilitating the assembly of plants and animals. We conducted a trait-based approach to algal assemblages associated with the freshwater bryozoan, Pectinatella magnifica. Association with algae leads to the inner bodies of the bryozoans being colored green; this is frequently observed in the large rivers of South Korea. We collected the green-colored gelatinous matrices and phytoplankton from waterbodies of the two main rivers in South Korea. Algal assemblages within the colonies and in the waterbodies were compared using the three diversity indices (richness, diversity, and dominance), and the composition of functional groups (FGs) and morphologically based functional groups (MBFGs) between the colonies within and outside of P. magnifica colonies. The most dominant and common species within the colonies were Oscillatoria kawamurae and Pseudanabaena catenata, both of which were assigned to the same FG (codon S1). Of the algal assemblages within the colonies, the dominance was higher, while the richness and diversity were lower, than those in the waterbodies. There was variation in the compositions of FGs and MBFGs in the waterbodies outside the colonies. Total nitrogen and orthophosphate led to dominance, and were significant factors for the variation in FGs in the waterbodies, whereas there were no such significant factors within the colonies. This trait-based approach to the community structure of associated algae provides the status and habitat gradient of these communities, which are stable, isolated, and consistent with the overgrowth of shade-adapted tychoplanktonic cyanobacteria.

  • This paper examines a highly used social networking site (SNS) by studying the behavior of more than 11 million members over a 20 month period. The importance of the most highly active members to the overall network is demonstrated by the significant fraction of total visits by extremely active members in a given period but such members have surprisingly short lifespans (an average of only 2.5 months) as social hubs. We form and test a number of hypotheses concerning these social hubs and the determinants of their lifespan. We find that the speed of achieving social hub status increases the lifespan of a social hub. The norm of reciprocity is strongly confirmed to be present in the social hub population as visits are reciprocated. We also find that increasing local dominance in terms of activities over neighboring agents leads to a longer lifespan of a social hub. Contrary to expectations, local clustering in the vicinity of social hubs is smaller (rather than larger) than overall clustering. We discuss managerial implications in the paper.

  • Objectives: The purpose of this study was to evaluate the influence of eye dominance on color perception, and shade matching. Materials and Methods: A total of 104 participants were selected for the study. There were 3 groups: Group I: 3rd and 4th year dental students and interns (n = 40); Group II: postgraduates (n = 34); Group III: senior residents and faculty members (≥ 6 years of clinical experience) (n = 30). All participants were evaluated for congenital color blindness with Ishihara plates, their dominant eye with Mile's test, and their color perception with the Farnsworth-Munsell 100 hue test. The shade guide test was used for shade matching with a second corresponding set of Vitapan classical shade guides. Results: The results of Mile's test revealed that 60.6% were right-eye dominant and 39.4% were left-eye dominant. There was a statistically significant difference among all participants between the dominant eye and the non-dominant eye in shade matching. Conclusions: The dominant eye has a positive effect on shade matching and the ability to match shades becomes better with an increase in clinical experience.

  • 한강하구 염하수로 주변의 조석 조류 변형과 창 낙조 우세를 분석하기 위해서 4개 정점에서 동기간에 관측한 조류자료와 기 관측된 조석자료를 분석하였다. 조석 및 조류의 변형 정도는 $M_4/M_2$ 진폭비를 분석한 결과 상류로 갈수록 증가하며, 조석의 상대 위상차($2M_2-M_4$)를 계산하면 모든 정점의 값이 $180^{\circ}C$ 이하로 창조 우세를 보여준다. 그러나 조류자료의 통계분석 결과를 보면 조석 조화상수의 상대 위상차 결과와는 다르게 최강 평균 낙조가 창조에 비하여 강하게 나타나며, 정조시각을 이용하여 창조, 낙조 지속시간을 계산하면 낙조 지속시간이 길게 나타난다. 각 조류 관측정점의 주축 방향 유속성분의 상관도를 분석한 결과 인천항 이후 염하수로 북쪽입구까지는 상관도 값이 0.9 이상으로 높게 나타났다. 조류 분석결과에서 보여지는 낙조가 우세하고 낙조 지속시간이 긴 형태의 원인을 분석하기 위해서 조화분해 결과를 재구성하였다. 주 분조($M_2$)와 천해 분조($M_4$)를 결합하면 창조가 우세하고 낙조 지속시간이 긴 전형적인 창조우세 형태의 곡선이 나타난다. 그러나 이 곡선에 조류 성분의 산술 합으로 계산한 비 조류성분(잔차류)의 값을 더하면 낙조가 강해지고 낙조 지속시간이 긴 형태로 나타난다. 즉, 천해분조에 의해서 발생하는 상류방향의 흐름을 극복하는 담수와 하구 비선형 효과에 의해서 생성되는 장주기 조류성분과 같은 낙조방향의 평균적인 흐름이 존재하기 때문에 독특한 낙조심화 현상이 염하수로에서 나타난다.

  • 이 논문은 1970년대 유신체제 시기 박정희 대통령의 집권욕과 폭압성을 주제로 통일주체국민회의의 반민주성, 대통령긴급조치의 위법성, 부마항쟁진압의 폭압성에 관한 사례연구로 구성되어 있다. 즉 유신헌법 제정으로 제도화된 대통령 선출기구인 통일주체국민회의, 대통령이 장기집권을 위해서 대학생과 재야세력을 탄압하기 위한 수단으로 단행한 대통령긴급조치, 그리고 유신체제와 박정희 대통령의 집권욕과 폭압성에 대해 저항하고 폭력에 맞선 부마항쟁으로 되어 있다. 이 사례 분석을 위한 연구방법으로는 인과관계 측면(유신체제의 성립과 붕괴), 법 제도적 측면(유신헌법과 대통령긴급조치), 그리고 행태적 측면(박정희 대통령의 집권욕과 폭압성)을 적용했다. 유신헌법을 통해 제도화된 통일주체국민회의와 대통령긴급조치에 의한 유신체제의 성립으로 박정희 대통령은 집권욕과 폭압성에 의한 장기집권에 집착했다. 그리하여 시대정신과 민주헌정의 기틀을 유지하지 못한 것이 대학생과 시민들의 반체제운동의 일환인 부마항쟁을 촉발시키면서 유신체제가 붕괴되기까지의 과정을 이 논문에서는 고찰하고 있다.

  • 본 연구는 의미적 속성을 가진 시각과 청각자극 간의 SOA(stimulus onset asynchrony)가 시청각 통합 현상에 미치는 영향을 살펴보고자 하였다. 시청각 통합 현상 중 표적을 의미하는 자극의 양상이 두 개 이상인 경우 표적에 반응이 빠르고 정확한 중복 표적 효과(redundant target effect)와 청각 자극에 비해 시각 자극에 대한 반응이 빠르고 정확한 시각 우세성 효과(visual dominance effect)를 중심으로 살펴보기 위해서 시각과 청각 단일 양상 표적 조건과 다중 양상 표적 조건을 구성하여 조건들의 반응시간과 정확률을 살펴보았다. 그 결과, 시 청각자극의 SOA가 변하더라도 중복 표적 효과는 이에 영향을 받지 않는 것으로 나타났으며, 두 자극 간의 SOA가 100ms 이상인 조건에서는 청각자극의 우세현상이 나타났다. 이러한 결과는 중복 표적 효과의 경우 두 양상자극 간의 SOA가 변하더라도 안정적으로 지속된다는 점을 시사하며, 청각자극의 경우 시각자극에 비해 약 100ms 이상의 시간적 이득조건이 마련되었을 때에 비로소 우세한 정보처리의 행동결과가 도출될 수 있음을 시사한다.
