Growth of any country rest in the consumption of industrial wastes for its infrastructure amenities. Countries like India positively desires a vital utilization of industrial waste resembling paper sludge in the construction industry to make various building materials. Also, it is the duty of all civil engineers or researchers to attach them in mounting new materials from the waste dumped as land fillings. In every construction project, about 70% of cost accounts for the procurement of materials. If this, can be minimized consequently the cost of construction will certainly be condensed. Research has established that the waste paper sludge can be reused in the construction field for a probable scope. The construction diligences munch through a massive quantity of non-renewable resources. On the additional dispense, more waste paper board sludge ends up in landfills or dumpsites than those recycled. Consequently, waste paper sludge for use as a construction material composes a step towards sustainable development. Keeping this in mind an endeavor has been made to utilize paper board sludge acquired from the paper board industry and used with several pozzolanic and cementitious materials for a specific purpose. The addition of paper sludge has been varied from 0% to 20% by weight of cement. The tests done with the samples expose that four samples showed significant outcomes with remarkable strength and durability properties which guide to move for the next phase of research for producing lightweight tiles.

Recently, there has been the gradual growth of the public in rural amenities, hobby farming works, much more urbanities, and especially near-retires. However, in spite of popular preference to ruralities, little has been known about their demand on retired rural life. Therefore, this study examined urbanites' attitude to preparatory works for out-migration, preferred residential site condition and life styles in the countryside. For the purpose, data were collected from the survey with the sample of 62 urban trainees who were studying farming technology in department of training on agricultural technology of Korea National Agricultural College, RDA. We carried out the experience farming to candidate with using the abandoned sericultural facilities which are the silkworm rearing house and mulberry fields. The 71% of urban trainees, who answered in this survey, hoped to move into countryside after retirement and to make a monthly income of $1,000 from agriculture. The age distribution of sericulural farmers is about 79% more than that of 60 years old. In the experience farming works. The two candidates made 1,977$ with net income through 32 days worked in spring season. In autumn season, the couple candidates made 1,317$ with net income through 23 days worked. Knowledge of these results will be important to policy-makers and to understand the role that retirement in-migration play in stimulating economic growth of rural agricultural farmers.

Recently, the interest in marine leisure activities has been growing rapidly with the work-life balance trend. In response to this demand, the Korean government is supporting fostering and revitalizing the relevant industries and facilities. In particular, a marina has been making efforts to change itself into a resort with multiple amenities instead of a simple mooring facility. However, the facilities in a marina for the transport of marine leisure equipment mostly consist of cranes and boat-lifts using ropes, which can result in incidents such as damage and accidents during lifting or movement. This paper proposes the equipment and support system for the safe transportation of marine leisure ships. Aluminum transport equipment was designed by performing a structural analysis to achieve a lighter weight than the existing steel products. In addition, a safety support system with alarms for tilting or obstacles and a slope monitoring system was developed to enhance the safety during operation and transportation. The safety support system developed in this study was implemented and installed in the transport system, and verified through commissioning on land.

The paper examines the impact of the COVID-19 pandemic on the stock market prices. The vector autoregression model (VAR) has been used in this analysis to survey 341 stocks on the Ho Chi Minh City Stock Exchange (HOSE) for the period from January 23, 2020 to December 31, 2020. The empirical results obtained from the analysis of 11 economic sectors suggest that there is a statistically significant impact relationship between COVID-19 and the healthcare and utility industries. Additional findings show a statistically significant negative impact of COVID-19 on the utility share price at lag 1. Analysis of impulse response function (IRF) and forecast error variance decomposition (FEVD) show an inverse reaction of utility stock prices to the impact of COVID-19 and a gradual disappearing shock after two steps. Major findings show that there is a clear negative effect of the COVID-19 pandemic on share prices, and the daily increase in the number of confirmed cases, indicate that, in future disease outbreaks, early containment measures and positive responses are necessary conditions for governments and nations to protect stock markets from excessive depreciation. Utility stocks are among the most severely impacted shares on financial exchanges during a pandemic due to the high risk of immediate or irreversible closure of manufacturing lines and poor demand for basic amenities.

Accurate knowledge of land use/land cover (LULC) features and their relative changes over upon the time are essential for sustainable urban management. Urban sprawl growth has been always also a worldwide concern that needs to carefully monitor particularly in a developing country where unplanned building constriction has been expanding at a high rate. Recently, remotely sensed imageries with a very high spatial/spectral resolution and state of the art machine learning approaches sent the urban classification and growth monitoring to a higher level. In this research, we classified the Quickbird satellite imagery by object-based image analysis of Dempster-Shafer (OBIA-DS) for the years of 2002 and 2015 at Karbala-Iraq. The real LULC changes including, residential sprawl expansion, amongst these years, were identified via change detection procedure. In accordance with extracted features of LULC and detected trend of urban pattern, the future LULC dynamic was simulated by using land transformation model (LTM) in geospatial information system (GIS) platform. Both classification and prediction stages were successfully validated using ground control points (GCPs) through accuracy assessment metric of Kappa coefficient that indicated 0.87 and 0.91 for 2002 and 2015 classification as well as 0.79 for prediction part. Detail results revealed a substantial growth in building over fifteen years that mostly replaced by agriculture and orchard field. The prediction scenario of LULC sprawl development for 2030 revealed a substantial decline in green and agriculture land as well as an extensive increment in build-up area especially at the countryside of the city without following the residential pattern standard. The proposed method helps urban decision-makers to identify the detail temporal-spatial growth pattern of highly populated cities like Karbala. Additionally, the results of this study can be considered as a probable future map in order to design enough future social services and amenities for the local inhabitants.

Camel milk has a significant and pivotal role in the diet of people residing in semi-arid and arid regions. Ever since ancient times, marketing of camel milk has remained insignificant due to nonexistence of processing amenities in the camel nurturing areas, hence the utilization of unprocessed camel milk has continuously remained limited at family level by the nomads. Due to the superior medicinal values and health promoting effects, incredible growth in the demand of camel milk and dairy products have been noticed all over the world during last two decades. Such emergence has led dairy industry to provide diversified camel dairy products to the consumers with superior nutritional and functional qualities. In contrast to bovine, very few food products derived from camel milk are available in the present market. With the advancements in food processing interventions, a wide range of dairy and non-dairy products could be obtained from camel milk, including milk powder, cheese, yogurt, ice cream, and even chocolate. In some regions, camel milk is used for traditional dishes such as fermented milk, camel milk tea, or as a base for soups and stews. Current review highlights the processing opportunities regarding the transformation of camel milk into various dairy products via decreasing the inherent functionality that could be achieved by optimization of processing conditions and alteration of chemical composition by using fortification method. Additionally, future research directions could be devised to improve the product quality.

This report designs a landscape plan of six reservoirs in Sihung city which has possibilities both in development and in destruction. The report suggests how to create a leisure space in harmony with the surroundings in Sihung city. Building a leisure town will create the local residents' demand in recreational activities and improve the amenities. Therefore this study analyzes eco-friendliness of the land, conditions of fauna and flora, the quality of water and the usage figures of the six reservoirs so as to develop those six reservoirs more eco-friendly. Based on environmentalism, the leisure spot development plan attribute the ultimate importance to local residents' pleasant leisure time and recreations. With this master plan, the report suggests expanding the city's green space, since the city has under 50% out of the optimal percentage of green space per person. In addition, the report intends to plan each six reservoirs developed separately but organically connected at the same time that those six can put together and become a Sihung Green Way which makes the city's leisure space a belt. Apportioning the six reservoirs development levels in order to balance the development, accumulating and arranging buildings and facilities in available spaces according to the governing law, and creating resting area, promenade and parking lot to make an eco-city. Also the report suggests conserving environment and regulating contamination such as ban on fishing to move forward sustainable development. Since the adventives predominate the site, introducing indigenous plants should be necessary soon.

After World War II, Japan experienced a great political and social shift, which brought a concern of emerging public landscape in urban development. This paper analyses the management of the aesthetic intentions in urban design effort. We reviewed the development of various public installation of artworks concerning urban landscape aesthetics through its administrative process in chronological order. The monuments during the first decade marked a shift in emphasis from the militarism of the pre-war and wartime period to one of peace. However, some of the monuments and sculptures are not immune to controversy. This became an issue that could no be ignored by public officials whose responsibility was to place the sculptures while maintaining sensitivity to public opinion. As public administrators began to consider the possibility that sculptures may contribute to improving public amenities, the contextual concepts were basically ignored. Some of the programs in 1970s began to show more respect to the context, while other programs in this period expressed more interest in educational aspects of sculptures in the public spaces. Urban development projects also seek to introduce artworks integrated to their urban design concepts in 1990s. Generally, the administrators responsible for these programs were rarely trained in any relative field study other than public administration. Installing sculptures tended to be considered as part of public works projects on the level of urban planning and construction. The general public is basically removed from participating in the critical decisions that actually impact their lives in relation to the artworks. In conclusion, public art in japan has unique social and historic background both in its advantages and disadvantages. Issues pertaining to art in public spaces have evolved over the decades as the term "sculpture pollution" began to appear by the mid 1990s. most of the problems originated in either the lack of monumentality, contextual consideration, quality, or public participation. From another point of view, these programs played great roll in the development of modern Japanese sculpture and patronizing process, and the creation of new urban landscape with aesthetic value. In this sense, they must be considered as successful and noteworthy examples of cultural administration and urban design policy.

현재, Covid-19의 밀접접촉자를 찾아내어 진단검사를 통해 Covid-19 확산을 차단하고 있다. 하지만 확진자의 잠복 기간이 2주가 되고, 확진자의 동선을 추적하여 접촉자를 찾기에 많은 인력과 시간, 비용이 소요된다. 특히, 확진자의 수가 증가할수록 접촉자를 찾아 사전에 차단하는 비용이 기하급수적으로 증가하여 한계점을 가진다. 접촉자를 찾기 위해 전 국민이 상점이나 식당 등 편의시설을 방문할 때마다 전자출입명부를 기록해야 하는데 이는 개인의 위치 정보에 대한 프라이버시 침해 가능성이 높다. 본 연구에서는 자신의 위치와 시간을 실시간으로 저장하고, KDCA에서 수집된 감염자의 동선 정보를 다운받아 겹치는 지점이 있을 경우에 사용자에게 통지하여 사전에 진단검사를 유도하는 시스템을 설계하고자 한다. 제안 기법은 상점을 방문할 때 전자출입명부를 기록해야 하는 번거로움을 해결하면서 개인정보를 사전에 KDCA에 제공하지 않아 프라이버시 침해를 차단할 수 있다.

헤도닉 가격 모형은 부동산 가격에 영향을 미치는 여러 요소를 모델링하는데 활용되는 대표적 방법이다. 부동산 가격은 전용면적, 방의 개수, 주차공간과 같은 내재적 속성 뿐 아니라 주변 선호/비선호시설의 존재여부에 따라 영향을 받는다. 주변 입지시설의 경우, 그 영향을 파악하기 위해서는 해당 부동산과의 인접거리를 설명변수로 사용하게 된다. 그러나 다수의 입지시설이 인접해 있는 경우에는 설명 변수 간 다중공선성이 발생하는 문제가 존재한다. 본 연구에서는 분산팽창지수 및 능형회귀분석을 이용해 다중공선성을 파악하고 유의한 설명변수를 선별하는데에 활용하였다. 이들 기법을 서울시 구로구 아파트들에 적용한 결과, 전철 차량 기지, 디지털 단지 및 위도에 해당하는 변수간의 다중공선성을 파악하였으며, 능형회귀분석을 통해 적합한 변수들을 체계적으로 선정할 수 있었다. 본 사례를 통해 상기 기법들이 더 정확하고 적정한 헤도닉 가격 모형을 구축하는데 중요한 보완적 기능을 해준다는 것을 알 수 있다.
