We are developing empirical space weather (geomagnetic storms, solar proton events, and solar flares) forecast models based on solar information. These models have been set up with the concept of probabilistic forecast using historical events. Major findings can be summarized as follows. First, we present a concept of storm probability map depending on CME parameters (speed and location). Second, we suggested a new geoeffective CME parameter, earthward direction parameter, directly observable from coronagraph observations, and demonstrated its importance in terms of the forecast of geomagnetic storms. Third, the importance of solar magnetic field orientation for storm occurrence was examined. Fourth, the relationship among coronal hole-CIR-storm relationship has been investigated, Fifth, the CIR forecast based on coronal hole information is possible but the storm forecast is challenging. Sixth, a new solar proton event (flux, strength, and rise time) forecast method depending on flare parameters (flare strength, duration, and longitude) as well as CME parameter (speed, angular width, and longitude) has been suggested. Seventh, we are examining the rates and probability of solar flares depending on sunspot McIntosh classification and its area change (as a proxy of flux change). Our results show that flux emergence greatly enhances the flare probability, about two times for flare productive sunspot regions.

Gender equality has been expected to realize fully in the process of globalization. According to neo-liberal, which views globalization as a rational development, irrational discrimination by culture will disappear. But some feminists criticize globalization as a patriarchal phenomenon. So in this paper, the extent to which women in Korea have achieved equality with men in the workforce is assessed through an examination of the gender gap during 1993-2003. As the result, it was found that women had still lower status than men in spite of laws established to promote gender equality. Then to explore the direction for eliminating the patriarchal gaps, women in traditional Korea were reviewed. Traditionally women were oppressed by the practice of Naeoe differentiating between women and men. But on the other hand it made women to have equal status with men by maintaining their own productive area. So it was suggested that differentiation should be considered as a source of power to be adopted into women's activitism such as NGOs or international women' movement to achieve full equality in inequitable globalization.

The saying likely as "In the rapidly-changing outside management environment, the light-weighted body only able to survive" means the 'lightness' in working space, reducing expenditure for immovable property and unnecessary facility, and also means the flexibility of facility which is ready to cope promptly with the approaching situation. For such reason, as many enterprises do not support an individual workstation for each person but by introduction of sharing system, also reducing the area for working space, they have made the immovable property expense per person curtailed. Though the reduction of the immovable property expense that subsequently gained by merely decreasing of working space brings a remarkable effect of retrenchment, there is also a worrying opinion that because of the narrowed working space than before, or by disappearing of private space, a possible non-productive effect which let working enthusiasm falls down might be brought. By practicing such investigating method, at the first stage survey, the Satisfaction of non-territorial and territorial office user and the order of required improvement are figured out, also arranged the appraisal items as 6 factors in total, and all of the factors were being influenced to the entire satisfaction in statistically meaningful level.

This study investigated the effect of home environment quality and fathers' parenting participation on school readiness of preschool children. The subjects were 101 5-years old children, mothers and teachers at child care centers located in the Gyeonggi area. Home environment quality was measured using a 'Korean Home Environment' questionnaire. Parenting participation by fathers was measured by 'Scale for Productive Roles of Fathers of Children in Their Early Childhood.' Lastly, the children's school readiness measured the 'School Readiness Inventory.' Collected data were analyzed using t-test, correlation analysis, and hierarchical multiple regression. The results of the study showed that the school readiness of preschool children differed by gender. The score of girls' school readiness was higher than boys' school readiness. Such difference was apparent in the school readiness areas of general knowledge, mathematical knowledge, and adjustment. There was a positive correlation between age and the school readiness of preschool children. An increase in children's age also increased school readiness in the areas of linguistic knowledge, mathematical knowledge, and adjustment. Home environment quality and fathers' parenting participation directly influenced the school readiness of preschool children. The pattern of the results suggests that a desirable home environment and fathers' contribution in the family for children are critical components to prepare preschool children for elementary school.

소프트웨어 공학 측면에서 웹 기반 프로젝트는 상당히 비효율적인 분야이다. 웹 기반 시스템을 개발하기 위해서는 사용자 인터페이스 디자이너가 먼저 화면 레이아웃을 설계한 후 그 화면의 레이아웃 소스를 가지고 다시 비즈니스 로직 개발자가 코딩을 하여 프로젝트를 완성한다. 유지 보수를 하는 경우에도 이와 비슷한 형태로 작업이 진행된다. 이러한 웹 기반의 소프트웨어 개발 방법은 JSP의 태그 라이브러리와 같은 다양한 형태로 제안되었으나 실제로 적용하는데 여러 가지 문제점이 있으며 기존의 C/S 기반의 소프트웨어 개발에 비해 생산성 측면에서도 매우 좋지 않다. 본 논문에서 제안한 웹 폼 시스템은 기존에 제안된 방법들이 해결하지 못한 사용자 인터페이스 디자인과 비즈니스 로직을 분리하여 웹 기반 소프트웨어의 개발 생산성을 향상시킬 수 있는 방안을 제시하였다.

While Janis Joplin is generally known as a hippie rock star of an untimely death to Korean audience, she is more strongly evoked in the image of blues mama in American context. Blues, definitely based on African-American vernacular tradition, is defined as a matrix, which is "a point of ceaseless input and output, a web of intersecting, crisscrossing impulses always in productive transit," to borrow Houston A. Baker's expression. This article explores how her life and music can be understood in blues tradition, especially in terms of personal and social transgression for which she was criticized, focusing on her blues performance. First of all, born and growing up in southern Texas between 1940s and 1960s, she expressed her innate suspicion against segregation and white supremacy, actively embracing rich black musical heritage of the area. Second, against the normative social and moral expectation of a middle class white woman to be a suburban housewife, she sought her own desire, whether it was professional ambition or sexual possibility. Third, beyond the selling image of a heterosexually lascivious blues mama, she dared to be a homosexual and bisexual, while it was not publically acknowledged. Along with her alcohol and drug dependence, such transgressions against normative social expectation were not made without her inner conflict, leaving a trace of trauma, hesitation, and the blues. While she was "buried alive in the blues," as a sacrifice at the altar of the 1960s, she still remains "alive" provoking "fire inside of everyone of us."

The study provides a quantitative and qualitative description of global research in the domain of quantum machine learning (QML) as a way to understand the status of global research in the subject at the global, national, institutional, and individual author level. The data for the study was sourced from the Scopus database for the period 1999-2020. The study analyzed global research output (1374 publications) and global citations (22434 citations) to measure research productivity and performance on metrics. In addition, the study carried out bibliometric mapping of the literature to visually represent network relationship between key countries, institutions, authors, and significant keyword in QML research. The study finds that the USA and China lead the world ranking in QML research, accounting for 32.46% and 22.56% share respectively in the global output. The top 25 global organizations and authors lead with 35.52% and 16.59% global share respectively. The study also tracks key research areas, key global players, most significant keywords, and most productive source journals. The study observes that QML research is gradually emerging as an interdisciplinary area of research in computer science, but the body of its literature that has appeared so far is very small and insignificant even though 22 years have passed since the appearance of its first publication. Certainly, QML as a research subject at present is at a nascent stage of its development.

Objective: This study assessed the possible existence of genotype by environment interactions for milk, fat and protein yields in Holstein cattle raised in one of the most important milk production basins in Brazil. Methods: Changes in the genetic parameters and breeding values were evaluated for 57,967 animals from three distinct regions of southern Brazil, divided according to differences in climate. The genotype by environment interaction was determined by genetic correlations between regions, estimated by the restricted maximum likelihood, considering the animal model. Bull rankings were investigated to verify the ratio of coincident selected animals between regions for each trait. Results: The estimates of heritability coefficients were similar between two regions, but were lower in the third evaluated area, for all traits. Genetic correlations between regions were high, ranging from 0.91 to 0.99 for milk, fat and protein yields, representing the absence of a genotype by environment interaction for productive traits. The percentage of selection error between regions for the top 10% of animals ranged from 0.88% to 2.07% for milk yield, 0.99% to 2.46% for fat yield and 0.59% to 3.15% for protein yield. Conclusion: A slight change in genotype between areas was expected since no significant genotype by environment interactions were identified, facilitating the process of selecting Holstein cattle in southern Brazil.

This study uses bibliometric methods to analyze publications regarding the use of acupuncture in osteoarthritis over the past 20 years and presents an overview of global research trends. Publications related to acupuncture in osteoarthritis from 2003 to 2022 were retrieved from the Web of Science Core Collection Database. An analysis of the extracted records was conducted according to their publication year, research area, journal title, country, organization, author, and keywords. The VOSviewer program was used to visualize the research trends on acupuncture in osteoarthritis. An analysis of 380 articles indicated a consistent increase in the use of acupuncture for osteoarthritis treatment over the past 20 years. Many articles have been published in research areas such as "integrative complementary medicine" and "general internal medicine." The most prolific journal was Evidence-Based Complementary and Alternative Medicine. In terms of article publication, the most productive country and research organization were China and the Beijing University of Chinese Medicine, respectively. The most frequently occurring keywords were "acupuncture," "knee osteoarthritis," and "pain." This study used a bibliometric analysis to provide an overview of global research trends on acupuncture in osteoarthritis. These findings may suggest the future direction of research on the treatment of acupuncture in osteoarthritis.
