The present paper will be concerned to the investigation of the stress-strain field around the cavity that is loaded or partially loaded at the inner surface by the rotationally symmetric loading. The cavity of the spherical, cylindrical or elliptical shape is situated in a stressed elastic continuum, subjected to the gravitation field. As the contribution to the similar investigations, the paper introduces the new function of loading in the form of the infinite sine series. Besides, in this paper the solution of stresses around an oblong ellipsoid cavity, has been obtained using appropriate curvilinear elliptical coordinates. This analytical approach avoids the solutions of the same problem that lead to expressions that contain rather complex integrations. Thus the presented solutions provide the applicable and explicit expressions for stresses and strains developed in infinite series with easily determinable coefficients by the use of contemporary mathematical packages. The numerical examples are also included to confirm the convergence of the obtained solutions.

The purpose of this study is to examine the relation between the trend of art and fashion which predominate a certain time. In order to achieve this goal, this study intends to analyze how plasticity found in Mondrian's pictures are applied to modern fashion with its focus on formative elements. Mondrian was ahead of abstractionism, a major trend of contemporary art, and defined the theory of neo-plasticism. The theory of neo-plasticism defined by Mondrian is characterized by the limited expression of lines and shapes by using only vertical and horizontal straight lines, and right angles and four-sided figures weaved by the lines, and the use of achromatic color(black, white, and gray) in three primary colors(red, blue, and yellow). Based on his theory, he fully displayed the world of geometric abstraction. Mondrian's formative elements which have been applied in modern fashion can be divided into shape and color, For the element of shape, first, horizontal and vertical lines have been applied to patterns, trimmings, detail, and plane of textiles through simplification of design, representing proportion, balance, and stress in a silhouette, Second, plane and diamond shapes made of horizontal and vertical lines have been applied to textiles or patterns with uniqueness. For the element of color, first, three primary colors and achromatic colors are used to seek the aesthetics of balance and harmony that are produced in the strain of conflict through brightness, chroma, and complementary colors, Second, primary colors of high chroma and brightness which are much stronger than pictures are used to express a modern sense. Formative elements of neo-plasticism, which have been applied to modern fashion suggested by this study, are connected with the trend of art contemporary designers have borrowed, Accordingly, this study will become a very helpful material which provides designers with original ideas in developing materials and patterns which connect design with art.

Background: In contemporary China, most parents are dual-earner couples and there is only one child in the family. We aimed to examine the associations of parents' work stress with suicidal ideation among the corresponding adolescent. We further hypothesized that low parental support experienced by adolescents may mediate the associations. Methods: Cross-sectional data from school students and their working parents were used, with 907 families from Kunming City, China. Stress at work was measured by the effort-reward imbalance questionnaire. Perceived parental support was assessed by an item on parental empathy and their willingness to communicate with the adolescent. Suicidal ideation was considered positive if students reported thoughts about suicide every month or more frequently during the previous 6 months. Logistic regression was used to examine the associations. Results: We observed that parents' work stress was positively associated with low parental support, which was in turn associated with adolescent suicidal ideation. The odds ratio for parents' work stress and adolescent suicidal ideation was 2.91 (95% confidence interval: 1.53-5.53), and this association was markedly attenuated to 2.24 (95% confidence interval: 1.15-4.36) after additional adjustment for parental support. Notably, mothers' work stress levels exerted stronger effects on children's suicidal ideation than those of fathers. Conclusion: Parents' work stress (particularly mother's work stress) was strongly associated with adolescent's suicidal ideation, and the association was partially mediated by low parental support. These results need to be replicated and extended in prospective investigations within and beyond China, in order to explore potential causal pathways as a basis of preventive action.

Several genetic strategies have been proposed for the successful transformation and expression of microbial transgenes in model and crop plants. Here, we bring into focus the prominent applications of microbial transgenes in plants for the development of disease resistance; mitigation of stress conditions; augmentation of food quality; and use of plants as "bioreactors" for the production of recombinant proteins, industrially important enzymes, vaccines, antimicrobial compounds, and other valuable secondary metabolites. We discuss the applicable and cost-effective approaches of transgenesis in different plants, as well as the limitations thereof. We subsequently present the contemporary developments in targeted genome editing systems that have facilitated the process of genetic modification and manifested stable and consumer-friendly, genetically modified plants and their products. Finally, this article presents the different approaches and demonstrates the introduction and expression of microbial transgenes for the improvement of plant resistance to pathogens and abiotic stress conditions and the production of valuable compounds, together with the promising research progress in targeted genome editing technology. We include a special discussion on the highly efficient CRISPR-Cas system helpful in microbial transgene editing in plants.

As contemporary society has become more complicated, specialized, and segmented, people are experiencing more diverse types of stress. In particular, while several factors associated with job stress have been examined among nurses, who belong to a professional group, the existing research has made no quantitative assessments of stress that reflect temporal differences in individuals. Therefore, the aim of this study is to understand the effects of job stress on alpha-amylase with regard to the working hours of nurses, to assess the variations in jobs stress over time, and provide basic data to improve the quality of nursing services. Ninety nurses working in three shifts in general, emergency, and intensive care wards of a university hospital in D City participated in this study. Salivary alpha-amylase (SAA) was extracted and analyzed at two-hour intervals from 07:00 to 15:00 from nurses on the day shift and from 23:00 to 07:00 from those working the night shift. The SAA level was highest between 23:00 and 01:00 for nurses in general wards ($mean{\pm}S.D.\;39.00{\pm}14.88$) and between 11:00 and 13:00 for those in both intensive care units and emergency wards ($mean{\pm}S.D.\;67.50{\pm}62.93$ and $mean{\pm}S.D.\;39.67{\pm}35.96$, respectively). The characteristic variation in SAA was significant between 23:00 and 01:00 (p < 0.01) and for those in their fifties or older (p < 0.01). The activation ratio of alpha-amylase, a stress reactant, showed an increase when the sympathetic nervous system was activated by mental stress; in addition, job stress was manifested with the effect of awakening at different time segments and at different ages among the nurses. With the aim of raising the level of service based on the nurses maintaining their mental health, it is necessary to focus sharply on the time segment for critical control and to conduct repetitive studies to determine the divisions of eustress critical values as well as to expand the population.

This study aims to explore a biological interpretation of farming practices mentioned in 'Sallimgyeongje(山林經濟)', an agricultural literature published in late 18C, in order to substantiate its scientific practicality and suggest the sustainable direction of modern agriculture. First, the research revealed that weeds and pests were effectively controlled by interspecies interactions such as allelopathy, mutualism, and interplanting. Second, qualified seeds were selected without dependence on chemical treatments by using specific gravity and cold water immersion. Third, the literature proposed plowing methods based on the properties of the soil, which implicated an establishment of healthy landscape mosaic by imitating the succession and introducing the moderate disturbance. Fourth, the genotypes of 37 native rice varieties were speculated based on six phenotype standards, and some of them are expected to have high nutritional value and abiotic stress resistance.

In modern society, many adults seek emotional solace by reconnecting with their childhood memories through "kidult" culture, especially as single-person households increase. This trend spans fashion, collectibles, movies, animations, games, and character merchandise, with Hollywood playing a significant role in its growth during the 1980s and 1990s. Kidult culture allows adults to relieve stress, foster creativity, and strengthen social connections, enhancing their quality of life. As this culture gains mainstream acceptance, companies are producing diverse products featuring beloved characters, appealing to a wide age range. The rise in single-person households has amplified the importance of personal expression and individuality, driving the popularity of kidult culture. Companies are leveraging this trend to create innovative designs that resonate with consumer preferences. This cultural expansion promotes new design forms and aesthetics, reflecting the evolving relationship between design and consumption. Kidult culture's growth underscores its significance in contemporary consumer and design culture, offering valuable insights into modern societal trends.

This writing is to understand some trends and its meaning of Regionalism Architecture in Jeju Island since 1950's. This thesis began with an interest in the identity crisis implicit in the simultaneous striving for modernism and the so-called regional values in Jeju Island. Regionalism is a response in architectural terms to re-establish continuity in a given place between past and present forms, and also a unique result related to particular places, cultures and climates in region. This is one way of looking at the issues of regional identity. The study began by observing the general characteristics of contemporary ideas on Regionalism in Jeju architecture. This means that tracing the history of development of Regionalism architecture in research area is not the focus of this thesis. The thesis demonstrates that Regionalism architectures in Jeju shows some trends related to the local cultural elements (or ideas) such like traditional architectural forms, natural environment, local construction-materials, etc. In summation, in the perspective of Regionalism architecture,mostofbuildingsin Jeju bring out them only as vernacular architecture as it was once produced, by the simple combination and imitation without any creative interaction of the regional culture. I stress the point in this paper that, in over the last fifty years, there have been very narrowed attempts to design the regional values in the main, and also point out that there are problems in the manner in which local architects have gone about trying to define the regional themes. So, a grate depth is required to understand the phenomenon that Jeju area is with its various nuances of traditions, art, culture, climate and light and then to reinterpret it into the modern building type with all the high sense. In addition to that, some conclusions are reached on future directions and the significance of the study.

In contemporary advertising market, one of main trends is to speak surrealistic visual language which provides 'enjoyable spectacles'. Specially, in the beginning of 21st century, there discovered more and more exhibitions and discourses about surrealism reinterpreted from the viewpoint of postmodernism. Surrealism as a creative style of expression based upon free association, has been a great inspiration for fashion ads for commercial communication as well as fashion design since its origin. However, there has been ignored the idea of analyzing surrealistic image expressed in fashion ads in spite of their flood. Accordingly, the purpose of this study is to grasp its cultural meaning through analyzing aesthetic characteristics of surrealistic image expressed in fashion ads. It will provide a better understanding of surrealistic image in fashion ads reflecting popular taste and preference directly as popular visual culture, focusing on post modern context. A case study of surrealistic fashion ads limits to TV or print commercials and digital ads as image ads stimulating visual expressions. The Results can be summarized as follows. Surrealism is an avant garde style which deconstructs the established meaning system as well as the existing formalistic order and then put them together in the frame of 'dream' and 'unconsciousness'. Defamiliarization questioning the whole edifice of representation can be adapted to. By means of paradox and metaphor, unfamiliar new visual world can be represented. The plastic characteristics of surrealistic image in fashion ads are founded as surrealistic styling of time and space, distortion of object by methods of automatism, depaysement, parody and trompe-l'oeil which bring about the deconstruction of gestalt. Aesthetic values of surrealistic fashion ads appear as dualistic representation, allegoric symbolism, fantastic romanticism. Ultimately they lead to marvelous. mysterious, humorous visual effects. Foster reinterpreted these effects of surrealism from Freud's 'Uncanny Concept'. 'Uncanny' means the phenomenon recurring to familiar being defamiliarized by repression. Surrealistic fashion ads strengthen this shocking effect more and more dramatically in company with our post modern needs for fantastic adventure and thrilling spectacle. It can be thought that surrealistic fashion ads reflects uncanny as an alternative which can relieve us of our stress and anxiety and which realize our potential desire in contemporary post industrial stage.

Ruth Ozeki(Japanese-American female novelist)?s recent novel, A Tale for the Time Being (2013) draws our attention because the fiction shows very interesting fictional experiments, especially in terms of post-humanism. Indeed, the novel is not a science fiction at all which has been, and still is, the typical fictional field employed in the discussion for the transhumanism and posthumanism. It also does not include any cybogs, robots, or aliens which provoke the posthumanism-related issues like mind/body, human/nonhuman, nature/culture relations. Indeed, it seems "merely" represent realistic day-to-day lives of ordinary people living in contemporary Japan and Canada, and in very minute and particular details at that. Indeed, the central action of the main characters of the novel seems very traditional, that is on the one hand writing a diary by a teenage girl who is counting the days and weeks before her suicide and on the other hand reading it by a female novelist who happens to find her diary several years later. Nevertheless, I would like to suggest that underneath this traditional narrative surface are simmering post-humanist and post-anthropocentric worldviews beyond liberal Humanism which takes human beings to be exceptional against human or non-human others. Not only in narrative contents and characterizations but also through narrative structure and strategies, the novel enacts post-humanist and post-anthropocentric worldviews which are interestingly drawn from both age-old Buddhist ideas and modern eco-philosophy and quantum physics. I would like to stress that what triggers the author's fictional experiments helping our rethinking and redefining "what human beings are" and "what the relation between humans and nonhumans" is not merely intellectual interests but her keen and passionate response to the heart-breaking pains and sufferings of human and nonhuman beings caused by the contemporary natural-artificial catastrophes and techno-scientific predicaments.
