This paper is designed to find and develop new concepts for the sustainable traditional village in Korea. To this end, it is necessary that concern for the traditional village should diversify and expand, and not concentrate solely on the cultural properties and architecture-oriented historic elements. In consideration of this notion, this paper suggests introduction of maintenance and management as a practical concept for the embodiment of the sustainable traditional village. This paper aims to explore the concrete maintenance and management systems of Korean and Japanese cases, to analyze differences and characteristics between the two nation\\\\`s, and through these comparisons, to suggest sustainable maintenance and management methods for the traditional village in Korea. Primary data was collected by field and interview survey on each village in the two nations several times during about a two year period. The major findings of this paper are presented in three categories--maintenance management frame, maintenance management contents, and necessary principles for progressive maintenance management, and are as follows; In the first step, suggests the basic directions, boundaries, and systems for the maintenance and management of sustainable traditional villages. And in the second step, analyzes the relationship among the contents of maintenance and management methods with focus on the village space, village attraction, and village community. Our results suggests diverse maintenance and management contents for the sustainable village maintenance and management. Finally, the basic principles for the application, and use as valuable tools for sustainable village maintenance and management, are strongly recommended.

The traditional village, which is subject for this paper, can be defined as a community having unique combinations of natural, cultural, and social characteristics of that nation, which reflects settlement environments during hundreds of years. Now, in spite of tis potential power of traditional village, national strategies do not find satifsactory directions in Korea. In terms of this concenrs, this paper tries to analyze and diagnose about successful precedents(Tsumage village and Shiragawa village, Japan) with focus on the village management. And this paper aims to explore concrete management systems of Japanese cases, to find clues for practical application, and to suggest several instructive concepts in the light of management system of traditional village management. The analysis is progressed in three viewpoints(village space, village attraction, and village community). And it is extracted that diverse management systems are necessary to secure sustainable traditional village and their way of life, particularly in the face of the pressure of tourism. As a result of exploring of Japanese two cases, representative characteristics, which are found, are as follow; Fist, objective of management is not tourism development but maintenance of sustainable life system. Second, management systems are having not compulsory but spontaneous open decision making process, and in particular, village management is mainly operated by the local government and semipublic institute(inhabitants-oriented0 which have the strongest influential power in village composition units. Finally, village management programs are mostly experience-type and are composed of public law and regulations, diverse operation program, and individual efforts of inhabitants for village management. Because this paper mainly focused on two precedents, there should be more diverse cases. however, extracted conclusions have practical meanings for village management and can be used in re-establishing management concepts of Korean traditional villages.

Since FAO introduced the Globally Important Agricultural Heritage Systems(GIAHS) in 2002, 36 sites of 15 countries so far have been listed on GIAHS. This study aims to find the important agricultural heritages of Korea and to prepare the methods for them to be selected as GIAHS. We have analyzed the proposals of the 36 GIAHS listed in order to study the characteristics of their components of the agricultural heritage which worked for being selected. To analyze the components of the agricultural heritage first, agricultural heritage was classified into 13 types and 42 components in light of GIAHS criteria. Then central themes were set to analyze the relevant contents in the proposals. They were, the type of GIAHS Site, significant agricultural landscape, the agriculture-forestry-fisheries-livestock linkage systems, the multi-layered, inter-cropping, circulation cultivation systems, the soil and water management systems, the conservation of agrobiological diversity and genetic resources, the history of the agricultural heritage, the succession of traditional farming techniques, the cultural diversity and so on. Most GIAHS are located in mountains, grasslands, rivers and coasts, desert than in plains, through which GIAHS assure us that it is the heritage of human challenge to overcome the harsh geographic environment and maintain a livelihood. In these sites the traditional farming techniques are carried on, such as mountain clearings, terraced rice paddies, and burn fields, and the unique irrigation systems and agricultural landscapes are well maintained, and the eco-friendly traditional farming techniques utilizing abundant forest resources and agriculture are well handed down. The origin or home of crop growing, a variety of genetic crop storage, the world's largest crop producer and preserving cultural diversity are also important factors for the selection.

This paper describes a new rotor position sensorless control method for SRM drives based on an improved simplified flux linkage method. In the traditional simplified flux linkage method, every phases take turns conduction and current chopping control method is used. Every phases take turns conduction means turning on the incoming working phase while turning off the working phase. This conduction mode causes coupling between turn-on and turn-off angles, which goes against optimal efficiency or torque ripple minimization with sensorless speed control. In the improved simplified flux linkage method, turn-off angle is calculated by flux loop, the turn-on angle can be given arbitrarily and has no relations with the turn-off angle, and the current chopping control method is used. The speed and rotor position can be estimated then. Finally, a sensorless SRM speed control system and an experiment platform with DSP are built and validity of this method is confirmed.

The significance of Boseong Tea Agriculture System lies in its harmonious coexistence with the surrounding environment, producing high quality teas and maintaining its biodiversity. Boseong Tea Agriculture System has been inscribed as Korea's Important Agricultural Heritage System (KIAHS) in 2018, but the Aging Society of tea farmers is threatening the conservation and succession of tea farming of the region. The study suggests designation of Boseong Tea Agriculture System as one of Globally Important Agricultural Heritage System (GIAHS), objecting conservation and succession of Boseong Tea Agriculture System. The study has reviewed GIAHS, KIAHS, Boseong Tea Agriculture System and surveyed tea farmers of Boseong for 3 months from March to May, 2020. The survey method includes face to face interview, phone interview (ones couldn't be reached for face to face interview) and in-depth interview of community leaders and experts, verifying the Aging Society status in Boseong tea agricultural industry. The survey result includes the following. Average age of Boseong tea farmers is 69.4 years old. Family tea-farming over two generation is 36% (54 household), and 79.4% (119 household) depends on 90% of income from tea production. The in-depth interview shows the aging tea farming society is most serious concern of tea farmers and GIAHS designation will support reliability and recognition of Boseong tea, helping conservation and succession of Boseong Tea Agriculture System. GIAHS designation will enhance and share the value of Boseong Tea Agriculture worldwide and be able to inherit the heritage for our future generation.

The Asian cultural landscape is a mirrored ecosystem of great complexity, formed by the interaction of man and nature, coupled with a host of ecological processes. The human dependencies on and environmental adaptation of the bio-organisms and the surrounding landscape constitute the typical cultural landscape. Islands are a good example of a cultural landscape, and each mosaic pattern of marine and coastal ecosystems reflects bio-cultural diversity. Along with land-use patterns, wise use of biological organisms and indigenous knowledge has expanded to islands in the Asia-Pacific region in several ways (sea current and human impact, etc.). Loss in biodiversity and landscape diversity as well as cultural diversity owing to global warming and rapid urbanization are emerging issues for island ecosystems all over the world. In order to sustain the historical coexistence between man and natural systems, we ecologists must continue to search for a holistic solution for academic consilience. In this paper, I present the vision and practical characteristics of island ecology with a view toward the conservation of the traditional landscape and bio-cultural diversities in the seascape.

In today's world, we find ourselves facing energy crises due to factors such as war and climate crises. To prepare for these energy crises, many researchers continue to study systems related to energy monitoring and conservation, such as energy management systems, energy monitoring, and energy conservation. In line with these efforts, nations are making it mandatory for energy-consuming facilities to implement these systems. However, these facilities, limited by space and energy constraints, are exploring ways to improve. This research explores the operation of a data collection system using low-performance embedded devices. In this context, it proves that an optimized version of RocksDB, a Key-Value store, outperforms traditional databases when it comes to time-series data. Furthermore, a comprehensive database evaluation tool was employed to assess various databases, including optimized RocksDB and regular RocksDB. In addition, heterogeneous databases and evaluations are conducted using a UD Benchmark tool to evaluate them. As a result, we were able to see that on devices with low performance, the time required was up to 11 times shorter than that of other databases.

There are many researches to make low-energy building. Lots of them focus on facility systems and insulation performance of building materials. However, not only systematic solutions but also approaches in early design stages are important to reduce energy consumption. Using BIM(Building Information Modelling) is considered as an effective and efficient way to simulate building energy and decide alternatives than traditional energy simulation because BIM based energy simulation makes to reduce much time for energy modeling. This study focuses on development of optimized geometry for super tall office buildings in Seoul, Korea. Specifically, length to width ratio and building orientation are main topics of this study because these two topics are the most basic and preceding factors deciding mass design. In this study, Revit MEP 2011 and Ecotect Analysis 2011 are used to make case models and calculate energy load in early design stages. Energy properties of material abide by Korean Standards for Energy Conservation in Building, Korean Guideline for Energy Conservation in Public Office and ASHRAE Standard in USA. This study presents best length to width ratio of plan and optimized orientation by evaluating the case models. Furthermore, this study suggests what should be considered for each case to decrease energy load.

We propose a transient evaluation scheme using a pressure measurement in a complicate pipeline systems. Conservation of mass and momentum equations in time domain can be transformed into a pressure head and flowrate relationship between upstream and downstream point in frequency domain. The impedance formulations were derived to address measured pressure at downstream to evaluate of flowrate or pressure head at any point of system. Both branched pipeline element and looped pipeline element can be generally addressed in the platform of the basic reservoir pipeline valve system. The convolution of time domain response function with measured pressure head from a downstream point provides flowrate or pressure head response in any point of the designated pipeline system. The proposed method was validated through comparison between traditional method of characteristics and the proposed method in several hypothetical systems.
