This research focuses on the life and works of architect Yi Hunwoo, who was active in early 20th century. Yi has been previously mentioned in a few research documents, but not as a main subject of interest. Thanks to digitalized historic databases, the authors of this research were able to access more information about Yi. It was discovered that he was born in Korea in the late 19th century and then attended the Nagoya Higher Technical School in Japan. After repatriation, he participated in a few public projects in Korea as an in-house architect at the Governor-General's office, then started his own practice and produced his individual projects. He also contributed articles on innovations in residential design to newspapers. Chronologically, his activities as an architect preceeded those of Park Gilyong, who has been conventionally regarded as the first Korean modern architect so far. This research would like to establish Yi Hunwoo as a historic figure whose professional career spanned the earlier stage of the Korean modern architecture, based on the records of his life and professional activities. The authors do not wish to present the architectural analysis nor evaluation of his works, which will be subject to future researches.

The Nannophya species in Korea was thought to consist of only Nannophya pygmaea. Previous studies on the species, including life history and development, conservation and restoration, habitat characteristics, genetic studies, distribution, behavior, and taxonomy have been conducted. However, a new Nannophya species, Nannophya koreana, was recently discovered in Korea. Moreover, this new species was found to inhabit both Korea and Japan. Thus, the previous studies should be reevaluated in relation to the new species, Nannophya koreana, and the latter should be treated as an endangered species worldwide given the current population instability.

Objective : The aim of this study was to take a census of elementary school children who have atopic dermatitis(AD) especially the residents of Je-Cheon. Method : We conducted a questionnaire survey of the elementary school children in Je-Cheon who have atopic dermatitis. 96 patients with AD were involved in the survey. The questionnaire was made up of their family history, past history, weaning food, breast-fed or not, dietary treatment and Children's Dermatology Life Quality Index(CDLQI), etc. The student's T-test was used for statistical analysis. Results : Parents and siblings brothers and sisters past history has an effect on patients with AD. With regard to past history of patients, allergic rhinitis was the most common ailment. Formula feeding was common in the group under 6 months of age and the mean age of the start of weaning was 7.25 months. Fruit juice and weaning food of powder type were the first weaning foods in this study. Many parents introduced a grain diet, live diet, bone - soup, egg, milk, cheese and bean curd to their children under 12 months of age. A restricted diet was the most common dietary treatment method in this study. The highest scoring question for CDLQI was itching; the lowest one was related to bullying. Conclusion : We analyzed the patients' family history, past history, weaning food, dietary treatment and Children's Dermatology Life Quality Index(CDLQI), etc. Through this survey, we better understand the actual conditions of elementary school children who had AD in Je-Cheon.

In 2019, the Aerospace Medical Association of Korea celebrated its 30th anniversary. On the other side of the world, it was also the 62nd anniversary of Russian launch Sputnik 1 of the world's first artificial satellite on October 4, 1957. In additionally, the world, especially the United States was shocked, when on November 3, 1957, Sputnik 2 blasted into Earth orbit with a dog named "Laika"; it was the role of veterinarian's activities for aerospace medical research and exploration. Veterinarians (Vets) are responsible for the health of all the animals for aerospace medicine whether on the ground or in space. Vets can enhance animal and public health and this knowledge of Vets and astronauts can extend their mission durations, go to nearby Earth Asteroids, Mars and other heavenly bodies to study their living and non-living characteristics. This review article is the brief history of the original growth of the veterinarian's activities for the aerospace medical research, in order to stimulate future strategies for improvements in the space life sciences and exploration.

Basic concept of this study is that architectural form as a material at present has meaning for the dweller's life on the past historical plane. Main method to recover history is ethnographic interview to dwellers. Secondary method is to analyze ancestors' writings, buildings in the background of the family photos, and past drawings and then to relate them with architectural form at present. Taxonomy is a starting point: general name of the building by outside researcher is quite different from it by inside dwellers. 'Haengrang-chae', servant quarter, has never been used for servants. Function of the haengrang went outside thatched houses at the front village. Firsthand observation or simple analyses as results of several precedent research are reexamined and criticized through this study. The mansion has moaning when we synthesize with the site location based on farming land and tenant farmer, and decline of the Kyongpo Lake. Territoriality of the mansion is reinterpreted to 'In-Out Structure' by Yin-Yang thinking, Dwellers extend buildings gradually to outside village, surrounding rear hills, the lake, DongHae Sea, and finally goes to imaginative Taoist heaven beyond real nature through the literary life. Confucius principle, known to govern upper class house at Yi Dynasty also affect general composition of the buildings: perpetuation of the family by ancestor worship, elder dominance and male dominance, fraternity love in the extended family, charity display by reception of guests, Taoist scholarly life harmonized with nature. However, the study of the particular life and usage of the dwellers reinforces or corrects general supposition of precedent researches. Unique shape of the house has been formed by convenience of the dwellers' life style, early modernized free thought over the rigid Confucius design principle, and female power in male dominant society.

Sin Dae-woo was a scholar representing the Ganghwa School in the late Joseon Dynasty. He was Jeong Je-du's grandson-in-law and also in charge of organizing Jeong Je-du's collection of writings. His three sons had a particularly close relationship with their father, so even when they published a collection of writings after his father's death, the names of the three were combined and marked as Jin-jak-shin. The records they left include Seokcheon Il-seung, who described the history of the family along with the collection of writings, Seongdo Il-rok, a diary of the time of Seongcheon Busa, and many letters exchanged over time. These records draw attention as they contain records of medical life, such as eye diseases that the family suffered, infectious diseases that caused many casualties, and Yakro (distilled herbal essence) that showed records of being used for treatment at the time. In this paper: 1) We examine the medicines, prescriptions, acupuncture, and medication used to treat eye diseases. 2) We carefully examine the epidemic, the responses of the parties to it, and the attitudes of those who stood at the boundary between death and life. 3) We look for clues to the use of Western-origin drugs called Yakro. Intellectuals of the time looked deeper into Lee Kyugyung's book and Seo Yu-gu's book on how they were reflected in Joseon's medical life. In conclusion, in the 18th and 9th centuries, we see that the influential families of the Ganghwa school freely brought in famous acupuncturists, used prescriptions that were included in medical books or not, and used Yakro from western origin that were not traditional methods of Joseon. Thus, we reveal that doctors of the Joseon had the capacity to pursue their medical life more actively and had open-minded exchanges than our existing perceptions.

Life table experiments were performed in order to examine the effects of food quality on Moina macrocopa fed with four kinds of algal foods, Botryococcus sp., Scenedesmus subspicatus, Selenastrum capricornutum, and Chlorella sp., at $20^{\circ}C$ . The temperature effects on M. macrocopa were also assessed, feeding Chlorella at $17^{\circ}C$,$20^{\circ}C$,$25^{\circ}C$, and a combination of $28^{\circ}C$ (light) and $25^{\circ}C$ (dark). The cartilaginous Botryococcs cells were Inappropriate food for Moina. Among the foods tested, Chlorella was the food of the best quality in all accounts of life history traits. Moina grown on Chlorella showed higher net reproductive rate ($R_0$), longer mean and maximum longevities, earlier mean age at maturity, longer mean carapace length at maturity, larger mean clutch size, and shorter mean time interval between clutch productions than those grown on Selenastrum and Scenedesmus. An optimal temperature for Moina was $20^{\circ}C$ . When Moina were grown on Chlorella at $20^{\circ}C$, they showed the highest r, the highest $R_0$, the shortest T, the longest mean longevity, the earliest mean age at maturity, the longest mean carapace length at maturity, and the largest mean clutch size. The results of life table experiments showed that the individual and population growth patterns were much more affected by low temperature $17^{\circ}C$, than by high temperature ($\geq 20^{\circ}C$). In the optimal condition, the r value was very high, 5.1 in $d^{-1}$. In conclusion, the food quality and the temperature are the most important factors to govern the size and continuity of Moina population, by which the individual growth rates and reproductivity of members in the population can be controlled to survive in their environment such as small and temporary water bodies in nature.

Life history characteristics, habitat landscape, and historical events are believed to have shaped the patterns of genetic variation in many taxa. The bony lip barb, Osteohilus vittatus, represent a potamodromous fish that complete all life cycle in freshwater and is widely distributed in Southeast Asia. It usually lives in small rivers and other freshwater habitats, and movement between habitats for either food or reproduction has been typical. These life history characteristics may promote gene flow, leading to less structured populations. However, many freshwater habitats are fragmented, which restricts gene flow. We investigate how this interplay has shaped patterns of genetic variation and phylogeographic structure within this species in the Sundaland, a biodiversity hotspot with a complex geological history, using mitochondrial cytochrome oxidase I (mtCOI) as a genetic marker. Forty-six mtCOI sequences of 506 bp long were collected from ten localities, eight geographically isolated and two connected. The sequences were used for population genetic and phylogeographic analyses. Our results showed a low genetic diversity within populations but high between populations. There was a deep phylogeographic structure among geographically isolated populations but a lack of such structure in the connected habitats. Among geographically isolated populations, sequence divergence was revealed, ranging from 1.8% between Java and Sumatra populations to 12.2% between Malaysia and Vietnam. An indication of structuring was also observed among localities that are geographically closer but without connectivity. We conclude that despite high dispersal capacity, the joint effects of historical events, long-term geographic isolation associated with sea level oscillation during the Pleistocene, and restricted gene flow related to lack of habitat connectivity have shaped the phylogeographic structure within the O. vittatus over the Sundaland.
