The objective of this study is to describe more positively and concretely the entity of traditional village through the quantitative and scientific analysis process using positive data. Dan-Gye, a traditional village in San-Cheong, has been populated since more than 500 years ago because of its ideal conditions for settlement. In this study, the fluctuations on the numbers of households in Dan-Gye were analyzed from the first settlement era to the present, and the transformations of housing sites and roads since 1913 were also analyzed. The results are as follows. 1) The village Dan-Gye has a history of more than 500 years, and the first inhabitants were the Ryus. As time went by, the Ryus' power became weak gradually, but the powers of the Kwons and the Parks who had flowed later into this village became prosperous to make up a prominent family village in the late period of Cho-Sun dynasty. Such powers had reached the peak in the early period of Japanese occupation, and although the powers became weak gradually after that time, those two families have overwhelmed other families in population and possession of large houses until now. But as the confucianism in every-day life fell off and the inhabitants moved to cities, the existence of a family community became meaningless. 2) The Kwons and the Parks have possessed the large parts of the village's housing sites. As time went by, the sites have been divided and fields have been changed to housing sites for the increasing families, and such division and change have been made chiefly on perimeter areas. 3) The characteristics of the road in Dan-Gye where traditional roads existed began to be destroyed by Japanese construction of new roads, and such destruction has continued due to the bank construction after a flood and the road constructions after 1970s.

Objective of the study was to investigate characteristics and meanings of the agricultural extension work during the period of Japanese $rule(1906{\sim}1945)$ through historical review on the work. The agricultural extension work during the period of Japanese rule was categorized into six patterns such as agricultural extension work by (1) government agricultural administration system, (2) agricultural experiment/research institute, (3) public school, (4) through the movement of rural development(Nong-chon-Jinheung Undong), (5) pro-government private organization, and (6) pure private organization. In conclusion, the characteristics of the extension work were defined; 1) a tool and/or method for colonial rule, 2) non-democratic and top-down extension work by administration, 3) authoritative and coercive work initiated by governmental system, 4) nation wide work of cooperation with public and private organization, 5) extension work focused on production increasing food and industrial materials, and 6) extension work initiated by government system without participation of pure private organization. The meanings of the extension work were reviewed in two ways. Firstly, in macro point of view, the work has negative meaning that was utilized as a tool and/or method for Japanese colonial rule, since the extension work was implemented under the direction of agricultural policy and was also directly related to the policy of Japanese colonial government. Secondly, in micro point of view, the work has significant meaning either negative or positive such as 1) beginning of modernized extension work based on experiment and research, 2) introduction of forcible agricultural extension work, 3) inducement of distrust tendency to agricultural policy and agricultural extension work, 4) establishment of basis in hardware of agricultural extension work, 5) production of experience in software of agricultural extension work, and 6) improvement of recognition toward scientific farming and improvement of level in agricultural techniques.
This study was carried out to lead the scientific management of the urban forest by estimating the forest environment. Forest environmental information was constructed using IDRISI system based on survey data, soil, plant, and digital elevation data. Forest environmental information was consisted of soil depth, soil organic content, soil hardness and parent rock as a soil environmental factor, and forest community, tree age, crown density as a plant environmental factor. Plant activity and topographic environment also were analyzed by using remote sensing data and digital elevation data. Environmental function of urban forest was estimated based on results of soil conservation and forest productivity. 70% of urban forest is located in elevation of lower than 200m and 55% of forest area have the slope of lower than 15 degree. Analyzed soil conservation status and forest productivity were almost the same as the soil chemical properties of collected soil sample and the vegetation index estimated using remote sensing data, respectively. Thus, the constructed forest environmental information could be useful to give some ideas for management of urban forest ecosystem and establishment of environmental conservation planning, including forests, in Taejon. The best forest environmental function was appeared at the natural ecology preservation zone. Current natural parks and urban parks were appeared to establish the environmental conservation plan for further development. The worst forest environmental function was appeared at the forest near to the industrial area and an overall and systematic plan was required for the soil management and high forest productivity because these forest was developing a severe soil acidification and having a low forest productivity.
Plant have developed sophisticated defence mechanisms against microbial pathogens. The recent accumulated information allow us to understand the nature of plant immune responses followed by recognition of microbial factors/determinants through cutting-edge genomics and multi-omics techniques. However, the practical approaches to sustain plant health using enhancement of plant immunity is yet to be fully appreciated. Here, we overviewed the general concept and representative examples on the plant immunity. The fungal, bacterial, and viral determinants that was previously reported as the triggers of plant immune responses are introduced and described as the potential protocol of biological control. Specifically, the role of chitin, glucan, lipopolysaccharides/extracellular polysaccharides, microbe/pathogen-associated molecular pattern, antibiotics, mimic-phytohormones, N-acyl homoserine lactone, harpin, vitamins, and volatile organic compounds are considered. We hope that this review stimulates scientific community and farmers to broaden their knowledge on the microbial determinant-based biological control and to apply the technology on the integrated pest management program.

The potential to differentiate into different cell lines, added to the easy and cost-effective method of extraction, makes adipose-derived stem cells (ADSCs) an object of interest in lymphedema treatment. Our study's goal was to conduct a comprehensive systematic review of the use of ADSCs in lymphatic tissue engineering and regeneration. On July 23, 2019, using PubMed/MEDLINE, Cochrane Clinical Answers, Cochrane Central Register of Controlled Trials, and Embase databases, we conducted a systematic review of published literature on the use of ADSCs in lymphatic tissue engineering and regeneration. There were no language or time frame limitations, and the following search strategy was applied: ((Adipose stem cell) OR Adipose-derived stem cell)) AND ((Lymphedema) OR Breast Cancer Lymphedema). Only original research manuscripts were included. Fourteen studies fulfilled the inclusion criteria. Eleven studies were experimental (in vitro or in vivo in animals), and only three were clinical. Publications on the topic demonstrated that ADSCs promote lymphangiogenesis, and its effect could be enhanced by modulation of vascular endothelial growth factor-C, interleukin-7, prospero homeobox protein 1, and transforming growth factor-β1. Pilot clinical studies included 11 patients with breast cancer-related lymphedema, and no significant side effects were present at 12-month follow-up. Literature on the use of ADSCs in lymphatic tissue engineering and regeneration demonstrated promising data. Clinical evidence is still in its infancy, but the scientific community agrees that ADSCs can be useful in regenerative lymphangiogenesis. Data collected in this review indicate that unprecedented advances in lymphedema treatment can be anticipated in the upcoming years.

Background: Ginseng is one of the well-known medicinal plants, exhibiting diverse medicinal effects. Its roots possess anticancer and antiaging properties and are being used in the medical systems of East Asian countries. It is grown in low-light and low-temperature conditions, and its growth is strongly inhibited at temperatures above $25^{\circ}C$. However, the molecular responses of ginseng to heat stress are currently poorly understood, especially at the protein level. Methods: We used a shotgun proteomics approach to investigate the effect of heat stress on ginseng leaves. We monitored their photosynthetic efficiency to confirm physiological responses to a high-temperature stress. Results: The results showed a reduction in photosynthetic efficiency on heat treatment ($35^{\circ}C$) starting at 48 h. Label-free quantitative proteome analysis led to the identification of 3,332 proteins, of which 847 were differentially modulated in response to heat stress. The MapMan analysis showed that the proteins with increased abundance were mainly associated with antioxidant and translation-regulating activities, whereas the proteins related to the receptor and structural-binding activities exhibited decreased abundance. Several other proteins including chaperones, G-proteins, calcium-signaling proteins, transcription factors, and transfer/carrier proteins were specifically downregulated. Conclusion: These results increase our understanding of heat stress responses in the leaves of ginseng at the protein level, for the first time providing a resource for the scientific community.
Half Value Layer calculations theoretically need prior specification of linear attenuation calculations, since the HVL value is derived by dividing ln(2) by the linear attenuation coefficient. The purpose of this study was to establish a direct computational model for determining HVL, a vital parameter in nuclear radiation safety studies and shielding material design. Accordingly, a typical gamma-ray transmission setup has been modeled using MCNPX (version 2.4.0) general-purpose Monte Carlo code. The MCNPX code's INPUT file was designed with two detection locations for primary and secondary gamma-rays, as well as attenuator material between those detectors. Next, Half Value Layer values of some well-known gamma-ray shielding materials such as lead and ordinary concrete have been calculated throughout a broad gamma-ray energy range. The outcomes were then compared to data from the National Institute of Standards and Technology. The Half Value Layer values obtained from MCNPX were reported to be highly compatible with the HVL values obtained from the NIST standard database. Our results indicate that the developed INPUT file may be utilized for direct computations of Half Value Layer values for nuclear safety assessments as well as medical radiation applications. In conclusion, advanced simulation methods such as the Monte Carlo code are very powerful and useful instruments that should be considered for daily radiation safety measures. The modeled MCNPX input file will be provided to the scientific community upon reasonable request.

KoFlux is a Korean network of micrometeorological tower sites that use eddy covariance methods to monitor the cycles of energy, water, and carbon dioxide between the atmosphere and the key terrestrial ecosystems in Korea. KoFlux embraces the mission of AsiaFlux, i.e. to bring Asia's key ecosystems under observation to ensure quality and sustainability of life on earth. The main purposes of KoFlux are to provide (1) an infrastructure to monitor, compile, archive and distribute data for the science community and (2) a forum and short courses for the application and distribution of knowledge and data between scientists including practitioners. The KoFlux community pursues the vision of AsiaFlux, i.e., "thinking community, learning frontiers" by creating information and knowledge of ecosystem science on carbon, water and energy exchanges in key terrestrial ecosystems in Asia, by promoting multidisciplinary cooperations and integration of scientific researches and practices, and by providing the local communities with sustainable ecosystem services. Currently, KoFlux has seven sites in key terrestrial ecosystems (i.e., five sites in Korea and two sites in the Arctic and Antarctic). KoFlux has systemized a standardized data processing based on scrutiny of the data observed from these ecosystems and synthesized the processed data for constructing database for further uses with open access. Through publications, workshops, and training courses on a regular basis, KoFlux has provided an agora for building networks, exchanging information among flux measurement and modelling experts, and educating scientists in flux measurement and data analysis. Despite such persistent initiatives, the collaborative networking is still limited within the KoFlux community. In order to break the walls between different disciplines and boost up partnership and ownership of the network, KoFlux will be housed in the National Center for Agro-Meteorology (NCAM) at Seoul National University in 2011 and provide several core services of NCAM. Such concerted efforts will facilitate the augmentation of the current monitoring network, the education of the next-generation scientists, and the provision of sustainable ecosystem services to our society.
A considerable change of the Korean nursing system has been made during the last decade not only in its philosophy but also in its function and structure to meet political and scientific need of the modern society. The main purpose of this study is to develope the new concept of comprehensive nursing care, both its Philosophy and ethics, as the basic of modern clinical nursing theory and practice. Comprehensive nursing care is the concept of human centered nursing care, and it helps a man to meet the basic physical, psychological, environmental, socioeconomic and teaching needs. It also helps him to help himself to meet these needs. This concept starts from the individualized nursing care and its ultimate goal is to improve a man to have a better position in his own community so that he may able to have a meaningful life. To accomplish this goal, an individualized nursing care plan as a nursing diagnosis and problem solving method should be set up for different patients with similar diagnosis to meet their needs, because each patient has a different social background. from this viewpoint, nursing is a science as well as abstruse humanity. The performance of comprehensive nursing care is a goal and issue of modern clinical nursing care. If nursing is a science and a profession for man, it should have ethics which recognize the dignity of man and offers infinite service voluntarily, and should be able to show leadership in carrying out the nursing responsibility. This leadership finds a person's potential and encourages him to utilize it. Such concepts should develop into a nursing ideology and this ideology should become a priority in comprehensive nursing care. The following statements are the conclusion of this study. 1) Modern nursing has been developed from disease centered nursing care to comprehensive nursing care based on humanity. The primary principle of nursing was to assist in the treatment of disease, but it has been changed to the professional nursing system independently. 2) The concept of nursing is one of continuous or endless scope of dispersion. It proves that nursing is grasping the professional responsibility to be able to coordinate scientific principles Patient health problems are according to scientific principles rather than adhering to nursing technical discipline as a daily work. 3) In chapter I and Ⅱ, the philosophy and ideology of nursing have been discussed and the flow of concept of clinical nursing and the rate of progress which emerges from naturalizing performance of the concept of comprehensive nursing in clinical nursing studied. The discussion developed the theory that a nurse should be to embody nursing ideas and objectives by establishing definite conviction of professions and study. 4) In chapter lil, nursing planning based on nursing diagnosis as a method to attain ideal nursing care for humanity with a definite idea of establishing philosophy of nursing was presented. 5) From the result of survey on patient needs about treatment and nursing, it was observed that all patient had emotional stress from unknown factors. Therefore it was concluded that nurses should not only educate the patient but also give them the opportunity to communicate freely their needs and anxieties. Furthermore complaints and doubts of the patient should be carefully noted and must be considered to meet these needs. 6) Patient teaching is the most important part of comprehensive nursing care. In chapter, Ⅲ, the important of patient teaching was emphasized by demonstrating the effect of patient teaching for diabetic patient. 7) In Chapter Ⅳ, from the result of the study on nurses attitudes to comprehensive nursing care, it was pointed that the evolution of nursing education and the establishment of a complete concept and value of comprehensive nursing was necessary.
