Hangzhou, in China, is a city that has a history as long as 2,300 years and is renowned due to its natural scenery of a beautiful lake surrounded by gentle green hills. This world wide famous scenery, known as West Lake(西湖), in 2011, was included in the World Heritage Landscape List. Though this place experienced enormous development and changes during thousands of years, historic sceneries did not disappear with the passage of time. In contrary, they are refined and increased attributing to protection efforts from past dynasties. Therefore, research in landscape transition is significant for building livable environment and preserving historical landscape. This paper mainly focuses on history transition of city Hangzhou. First of all, its urban construction and guiding ideology is analyzed. Then, deep meticulous research is carried out on development and preservation achievements for dynasty Tang, Song, Yuan, Ming and Qing. In the end, from a historical point of view, this paper will provide a new perspective which would contribute to sustainable preservation of historical landscape. From the Song Dynasty to the Qing Dynasty, the West Lake through several times of the rectification and construction, the present landscape was completed during thousand years several times through the construction.

This study aims to assess vulnerability in urban thermal environments of Seoul by using indicators frequently used in previous studies as well as effective indicators for spatial planning like urban and environmental planning. For this purpose, fifteen indicators that influence urban thermal environments such as heat waves, urban heat island effects, and urban micro-climates were identified based on literature reviews. Indicators for presenting urban structure and spatial properties were included; for example, building volume as 'exposure to climate', buildings completed before 1980 as 'sensitivity', and green space areas as 'adaptive capacity'. Among them, twelve indicators were applied to assess vulnerability in urban thermal environments of Seoul by using a GIS spatial analysis combined with fuzzy logic. The results show that the Gangnam area is identified as more vulnerable to a heat environment as compared to the Gangbuk area. In the Gangnam area, Seocho-gu, Gangnam-gu, Dongjak-gu, Yeongdeungpo-gu, Gangseo-gu were relatively high in vulnerability, while Dongdaemun-gu, Gangbuk-gu, Gwangjin-gu, Jungrang-gu were relatively high in the Gangbuk area. Gwanak-gu, Dobong-gu, Eunpyeong-gu, and Nowon-gu, which include forested areas, have low vulnerability in the sectors of 'exposure to climate' and 'sensitivity' due to the impact of Gwanaksan and Bukhansan. However, some areas with high vulnerability like Seocho-gu and Gangnam-gu may have lower vulnerability if the indicator 'status of air conditioning' from the sector of 'adaptive capacity' is used. This study could support the establishment of a practicable thermal environment policy and spatial planning to reduce heat-related risks in the field of urban and environmental planning.

This article explores how to incorporate the topic of the global environmental crisis called the "anthropocene" into archives studies and connect it to ecological practical reasons. In order to encourage discussion of archival studies, which puts the environmental crisis at a kind of archive constant value, this study seeks to examine the possibility of a quality shift in archival studies based on ecology. This article aims to go beyond the pragmatism of preparing improvements to eco-friendly record management, which is recently claimed by the "Green Archive" in Western archival studies. It calls for a new concept called 'ecological archive', which theoretically combines a more archives-based and ecological paradigm, and its epistemological transformation. Specifically, the ecological approach of archives is first discovered in the discussion of archival studies and at the same time, through the "ecological turn" of archives emphasized by recent anthropocene discourses, the concept of "ecological archive" emphasized by this article is embodied. This study uses 'ecological archive' as a universal and theoretical framework for archives as a basic concept for building ecological 'living' archives. In other words, for the construction of ecological archives, we reinterpret and extend so-called democratic values for archives, i.e., post-custodianship, community archives, and archives of emotions. Finally, the records of foot-and-mouth disease killing burial sites, an important site and example of the anthropocene tragedy, exemplifies the methodology of the actual application of ecological living archives. The case analysis aims to seek a new qualitative shift in record management that adapts to global ecological transformation, while also emphasizing the documentation by archival activism in ecological field practices jointly organized by archivists and citizens.

Typhoons and floods are natural disasters that occur frequently, and the damage resulting from these disasters must be in advance predicted to establish appropriate responses. Direct damages such as building collapse, human casualties, and loss of farms and fields have more attention from people than indirect damages such as increase of consumer prices. But indirect damages also need to be considered for living. The agricultural products are typical consumer items affected by typhoons and floods. Sudden, powerful typhoons are mostly accompanied by heavy rains and damage agricultural products; this increases the retail price of such products. This study analyzes the influence of natural disasters on the price of agricultural products by using a deep learning algorithm. We decided rice, onion, green onion, spinach, and zucchini as target agricultural products, and used data on variables that influence the price of agricultural products to create a model that predicts the price of agricultural products. The result shows that the model's accuracy was about 0.069 measured by RMSE, which means that it could explain the changes in agricultural product prices. The accurate prediction on the price of agricultural products can be utilized by the government to respond natural disasters by controling amount of supplying agricultural products.

Hybrid power storage system with emergency power function for demand management and power outage minimizes the investment cost in the building of buildings and factories requiring emergency power generation facilities, We propose a new business model by developing technology that can secure economical efficiency by reducing power cost at all times. Normally, system power is supplied to load through STS (Static Transfer Switch), and PCS is connected to system in parallel to perform demand management. In order to efficiently operate the electric power through demand forecasting, the EMS issues a charge / discharge command to the ESS as a PMS (Power Management System), and the PMS transmits the command to the PCS controller to operate the system. During the power outage, the STS is rapidly disengaged from the system, and the PCS becomes an independent power supply and can supply constant voltage / constant frequency power to the load side. Therefore, it is possible to secure reliability through verification of actual system linkage and independent operation performance of hybrid ESS, By enabling low-carbon green growth technology to operate in conjunction with an efficient grid, it is possible to improve irregular power quality and contribute to peak load by generating renewable energy through ESS linkage. In addition, the ESS is replacing the frequency follow-up reserve, which is currently under the charge of coal-fired power generation, and thus it is anticipated that the operation cost of the LNG generator with high fuel cost can be reduced.

The Seonwonjeon(璿源殿) in the Deoksugung Palace was initially the ritual space for the royal family affiliated with the Gyeongungung Palace during the Korean Empire. It is currently, however, empty, as a landscape restoration and maintenance plan is established as a part of the restoration project for the Seonwonjeon area. The following results were obtained through the historical investigation of the original form and examination of similar cases. First, the original topography of the backside grove, which had been in the Seonwonjeon area, is 3.0-5.0m higher than the base of the building, and a terraced flower bed(花階) was installed on the border of the green to set off the difference in a scenic way. Second, the backside grove was composed with fruit trees to bear fruits used in rites and pine trees which symbolize the ritual space. Third, resting places were established at both ends of the site for the convenience of visitors without interrupting the atmosphere of the sacred ground. A trail was also created inside the backside grove along with minimum landscape elements, including functionally required items, such as the signboard, bench, tree guard, ramp, street lights, and landscaping lights. Fourth, the information on original planting in the palace and ritual space was extracted through historical materials, such as literatures, antique paintings, and photographs along with site surveys. Based on the information acquired, a planting plan was established for the courtyard, pedestrian road, resting places, terraced flower bed, pine grove, and fruit tree garden, which constitute the landscaping space of the Seonwonjeon area.

This study studied the value of the spatial organization of the temple and the form of the garden located in the Seojang area in the southwestern regions of China. The value of the Lama temple was looked into by examining the relationship between Lamaism and Lama temple through the spatial organiz ation, building arrangement, and garden of temples that served as the center of history, culture, and politics of the time in the process of converging Buddhism introduced through China's central districts and India with folk beliefs in Seojang through the poor environment. To this end, the value of the space and garden of the Lama temple was derived through the representative Lama temples, Potala Temple, Norbulingka Temple, and Dazhao Temple. First, due to the unique environment in which ice caps and green areas coexist, the representative Lama temples in Seojang, Potala Temple, Norbulingka Temple, and Dazhao Temple, are widely distributed in the form of leaning against valleys and mountain ranges based on folk beliefs and Buddhism's Jatabuli(自他不二) and mandala. the target sites are largely divided into upper and lower spaces. Second, the target sites are largely divided into upper and lower spaces. Buildings for worship are located in the upper space, and spaces for practice and garden are located in the lower space. The garden existed in two main forms. Third, the garden existed in two main forms. Located in the center of the practice space, the garden had an ideal structure to plant bo tree to escape from the two false obsession and go to a world of truth that is with the Buddha behind the world through practice like Sakyamuni, and there was a garden around the temple where meditation and exchange took place. Evergreen coniferous forests are mainly planted in the forests.

(Research background and purpose) Urban development has also had a significant impact on the eco-friendly industry. In the public environment, citizens are stressed in many areas, which has really made them need a natural ecological environment. Therefore, it is necessary to improve the environment into an eco-friendly urban public facility that breathes the urban environment space inside the building with plants. To this end, we want to show that the urban environment can be improved through vertical gardens. And through this, we want to contribute to the popularization of vertical gardens. (Research Methodology) we will analyze the problems of the current public environment in the city and look at the supplementation around vertical gardens. (Result) A study of the public environment in the city found problems such as gloomy environment, poor use of space, dim color, and poor air quality, and wanted to create a vertical garden to provide a pleasant shelter. These vertical gardens have influenced urban public places with improved aesthetics, increased social value, insulation and soundproofing effects of buildings, reduced urban heat island effects, and increased urban green appearance. (Conclusion)This study uses vertical gardens in public spaces to design public spaces that are more comfortable and share mental and physical health together.

Philippines is the second world supplier of coconut by-products. As its first major genomics project, the Philippine Genome Center program for Agriculture (PGC-Agriculture) took the challenge to sequence and assemble the whole coconut genome. The project aims to provide advance genetics tools for our collaborating coconut researchers while taking the opportunity to initiate local capacity. Combination of different NGS platforms was explored and the Philippine 'Catigan Green Dwarf' (CATD) variety was selected with the breeders to be the crop's reference genome. A high quality genome assembly of CATD was generated and used to characterize important genes of coconut towards the development of resilient and outstanding varieties especially for added high-value traits. The talk will present the significant results of the project as published in various papers including the first report of whole genome sequence of a dwarf coconut variety. Updates will include the challenges hurdled and specific applications such as gene mining for host insect resistance and screening for least damaged coconuts (thus potentially insect resistant varieties). Genome-wide DNA markers as published and genes related to coconut oil qualitative/quantitative traits will also be presented, including initial molecular/biochemical studies that support nutritional and medicinal claims. A web-based genome database is currently built for ease access and wider utility of these genomics tools. Indeed, a major milestone accomplished by the coconut genomics research team, which was facilitated with the all-out government support and strong collaboration among multidisciplinary experts and partnership with advance research institutes.
