To establish the differential diagnosis and treatment method in bovine ovarian cysts, specially ovarian cysts with corpus luteum, serum progesterone concentration, rectal palpation and ultrasonography for measuring the cystic wall thickness and diameter of cyst and corpus luteum were investigated from 1,188 dairy cows with ovarian cysts. The plasma progesterone concentrations were 0.3$\pm$0.4 (mean$\pm$SD) ng/ml in 629 cows with follicular cysts, 3.7$\pm$1.1 ng/ml in 431 cows with luteal cysts, and 3.8$\pm$1.2 ng/ml in 128 cows with coexist of ovarian cysts and corpus luteum, respectively. The cystic wall thickness by ultrasonography were 1.6$\pm$0.4 mm in 629 cows with follicular cysts, 4.2$\pm$1.5 mm in 431 cows with luteal cysts, and 1.6$\pm$0.6 mm in 128 cows with coexist of ovarian cysts and corpus luteum, respectively. The days from initial treatment to insemination in follicular cysts were 28.1$\pm$6.9 days in treatment of GnRH alone, 15.9$\pm$2.9 days in combination of GnRH and dinoprost, and 15.1$\pm$3.1 days in combination of GnRH and cloprostenol. The percentages of cows conceived within 100 days after initial treatment were 61 %, 68% and 73% in treatment of GnRH alone, combination of GnRH and dinoprost, and combination of GnRH and cloprostenol, respectively. The days from initial treatment to insemination in luteal cysts were 3.8$\pm$0.6 days in treatment of dinoprost alone and 3.8$\pm$0.7 in cloprostenol alone. The percentages of cows conceived within 100 days after initial treatment were 69.5% and 68.5% in treatment of dinoprost and cloprostenol, respectively. The days from initial treatment to insemination in coexist of cysts and corpus luteum were 3.7$\pm$0.7 days in treatment of dinoprost alone and 3.8$\pm$0.6 in cloprostenol alone. The percentages of cows conceived within 100 days after initial treatment were 87% and 84% in treatment of dinoprost and cloprostenol, respectively. These results suggest that the best choice for treatment agents in ovarian cysts were combination of GnRH and PGF$_2$$\alpha$ in follicular cysts, and the PGF$_2$$\alpha$ in luteal cysts and in coexist of cysts and corpus luteum, respectively. In conclusion, it is suggest that ultrasonography is useful diagnostic tool for diagnosis and selection of treatment remedy in cystic ovaries of bovine.

How to see nature and how to define the relation between nature and the human certainly influence fundamental attitude toward nature and any results derived from the attitude. Therefore, in order to figure out a way for how the humans and nature should coexist, the thesis has began a philosophical analysis on the origin of the biomimetics. Based on findings from the analysis, the thesis would work on the features of biomimicry space, presenting related possibilities. For the philosophical characteristic of the thesis which was an ecological world view, introduced at the end of mechanical world view era, the ideas of Spinoza, Nietzsche, Bergson and Deleuze about nature were quoted. Based on what the philosophers have said, the thesis looks into successful ideas, designs and ways of living that nature has shown by itself. After all, the purpose of the thesis is to investigate the constantly changing space of the biomimetics by organic forms, autonomous systems and dividing programs. Based on this, nine cases were analyzed to derive the characteristics. As a result, organic forms, autonomous systems and dividing programs characteristics of ecological appear simultaneously in harmony. Biomimicry space can coexist with nature and the human is an effective way.

With development of global network in the 21th century, Korea has recklessly accepted western culture occurred damages to our identity. Development of traditions in a modern way contribute us Korea identity and future vision. This study has studied about combination traditional material and contemporary material with a view to diversified user's desires and individuality. This object shows that function and decoration coexist together, and design reflects mans life and thinking of the age as a reflection of sociocultural phenomena. The purpose of this work to create the object that meets mans requirement and even foresees the possibility of such requirement through converting into various appearances. Different concepts including closed singleness and expansion within open structure coexist one element. also this objects suggest that transformative expressions that simplify or transform, the forms can be freely changed by consumer's emotional changes. Here, light and form are experimented for creating diversified emotions. Considering design as positively responding behavior against the limitations given by environment instead of the solution to simple functional requirement, future design will find Its value more In more active response.

Purpose - The competitiveness of small- and medium-sized distribution companies has weakened with the entry of large distribution companies and Super Super Markets (SSMs). These companies have nationwide distribution networks and capital to take over street markets, thereby threatening the very survival of small merchants. In order to help these small- and medium-sized merchants, the government has recently reinforced distribution regulations for large distribution companies. Research design, data, methodology - The purpose of this study is to review domestic and foreign distribution regulations and to provide direction for establishing domestic distribution policies in the future. Results - The government must fully reassess its assistance policy for small and medium distribution companies to enable them to engage in differentiated competition with large retailers, based on their own strengths. This will allow all interested parties to coexist. Conclusions - Government assistance policies for small and medium distributors such as traditional markets must be reorganized. The objective is to ultimately protect small and medium distributors and allow them to coexist on their own strengths, rather than have regulations for large retail stores.

While online research is in full swing due to the COVID-19 pandemic, the Ministry of Education announced a plan to gradually switch face-to-face classes along with 'recovery of daily life'. As such, there is a need for an agreement that appropriately considers the position of promoting face-to-face classes, the position of studying online classes, and the position of students taking classes. Therefore, this paper intends to examine the teaching method of Coexist with COVID-19 centered on the student's position as the host of the class. It is expected that this study will be able to suggest directions for innovative teaching methods that reflect the considerations of teachers' teaching methods and analyze the needs of learners who are consumers.

Hutchinson (1961) proposed that the large number of species in most plankton communities is remarkable in review of the competitive exclusion principle, which suggests that in homogeneous, well-mixed environments species that compete for the same resources cannot coexist. The principle of competitive exclusion would lead us to conclude that only a few species could coexist in such circumstances. Nevertheless, numerous competing species in most natural habitats are able to coexist, while generally only few resources (niches) limit these communities. It is coined “the paradox of plankton” by Hutchinson. We reviewed some literature of the proposed solutions and give a brief overview of the mechanisms proposed so far. The proposed mechanisms that we discuss mainly include spatial and temporal heterogeneity in physical and biological environment, externally imposed or self-generated spatial segregation, horizontal mesoscale turbulence of ocean characterized by coherent vortices, oscillation and chaos generated by several internal and external causes, stable coexistence and compensatory dynamic under fluctuating temperature in resource competition, and finally the role of toxin-producing phytoplankton in maintaining the coexistence and biodiversity of the overall plankton populations. Especially we sited Roy and Chattopadhyay’s reviews and their toxin-producing hypothesis by phytoplankton. This review may be some information to study plankton communities and effect to put the solutions to the paradox that have been proposed over the years into perspective.

Although evolution of construction materials brought about development of modern architecture, they caused destruction of the environment and pollution. This problem is not a new one in terms of ecological esthetics and materials of sustainable architecture in light of the Eastern view of nature and this idea became a background of this study. The basic concept is to try to find out their characteristics from a perspective of ecological esthetics in relation to traditional building materials that nature, architecture, and humans coexist and live with each other to balance. Based on ecological esthetics and precedent studies on materials of traditional architecture, we investigated connections, expressive methods and characteristics in traditional residential construction space. This attempt has meanings in that it can propose a new framework of forming various viewpoints and spatial perceptions in relation to esthetics and traditional construction materials. The current study examined the characteristics by dividing them into tangible and intangible elements based on expressive features of elements of nature. The characteristics found by this process are not simply notion of physical materials, but plays a key role aesthetically and ecologically. Nature and materials take circulation of the law of nature, regulate energy, increase efficiency and play a major role in an economic way. Nature in itself becomes natural alternative energy, and plays its role in an invisible fashion. It examined how expressive characteristics of construction materials are reflected through analyzing residential space and Korean traditional garden having relationships with Eastern viewpoint of nature in relation to Korean traditional construction materials from a perspective of ecological esthetics. Findings of the above study indicate that expressive characteristics of Korean traditional construction materials from a perspective of ecological esthetics are that nature, space, humans coexist and live together and they will provide a clue to an alternative to solve ecological and environmental problems modern society will have in the future. Through this process, it provided a possibility that traditional space and materials can be succeeded in creative and new ways, and it found out the way for nature, space, and humans to coexist and a possibility of ecological esthetics. It addition, it will provide a key base as an alternative of sustainable design of the future.
