Since 1990, the Renewable Big Data Research Lab at the Korea Institute of Energy Technology has been observing solar radiation at 16 sites across South Korea. Serving as the National Reference Standard Data Center for Renewable Energy since 2012, it produces essential data for the sector. By 2020, it standardized meteorological year data from 22 sites. Despite user demand for data from approximately 260 sites, equivalent to South Korea's municipalities, this need exceeds the capability of measurement-based data. In response, our team developed a method to derive solar radiation data from satellite images, covering South Korea in 400,000 grids of 500 m × 500 m each. Utilizing satellite-derived data and ERA5-Land reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF), we produced standard meteorological year data for 1,000 sites. Our research also focused on data measurement traceability and uncertainty estimation, ensuring the reliability of our model data and the traceability of existing measurement-based data.

Social indicator survey can identify the state of society as a whole. When we create a policy, social indicator survey can reflect the public opinion of the region. Social indicator survey is an important measure of social change. Social indicator survey has been conducted in many municipalities (Seoul, Incheon, Busan, Ulsan, Gyeongsangnamdo, etc.). But, the result of social indicator survey analysis is mainly the basic statistical analysis. In this study, we propose a new data mining methodology for effective analysis. We propose a 3-step complex data mining in society indicator survey. 3-step complex data mining uses three data mining method (intervening association rule, clustering, decision tree).

The objective of this study was to determine the perceptions and knowledge of farmers of heat stress and tick resistance in cattle. A cross-sectional survey was conducted and 110 farmers in four villages in the sour and sweet velds of the Eastern Cape Province, South Africa were interviewed. The associations among area (municipality), gender, age, level of education, employment and religion were computed using Chi-square tests. The majority of the respondents had on average 4 bulls, 4 cows, 4 heifers, 4 calves, and 4 oxen. Milk was considered as the major (28.3%) reason for keeping cattle. Most farmers owned non-descript (72.6%), and Nguni (45.3%) cattle because of their heat tolerance (54.7%), tick resistance (54.7%), and milking ability (28.2%) traits. Excessive panting (56.6%) and disease transmission (76%) were regarded as the major effects of heat stress and tick infestation in cattle, respectively. About 50% of the respondents agreed that hair length influences tick resistance and 47.17% considered coat colour when acquiring cattle. In the sampled areas, ticks were prevalent in the summer season (93%), and 77.36% of the respondents use acaricides every fortnight. Gall sickness was reported to be a major problem in the cattle herds by 36.79% of the respondents. Our results showed that farmers in the two municipalities had knowledge of cattle adaptation to heat stress and tick resistance.

There is an increasing curiosity in Nordic as well as Far East Asian countries about senior cohousing, where the middle-aged and elderly people, 55+. form a community for independent living. What are the ideas behind senior cohousins? Why are people moving to senior cohousing community? What may senior cohousing provide and mean for individuals and groups of the elderly? Is senior cohousing a sustainable idea for future generations of elderly people? There is a curiosity among elderly people looking for interesting alternatives. Municipalities and state authorities hope that senior cohousing can contribute to the welfare of the elderly as the scope far support by the public sector is decreasing. Actors in the building sector are interested In investment and meeting the demands. In Denmark and Sweden the senior cohousing concept had a revival around 1985. In Denmark there has been a vivid discussion and plenty of books have been published. In Sweden there are few evaluations but an increasing interest. From different points of view, Danish, Swedish and Nordic as well as Far East Asian countries, there is a concern to explore and compare to get more facts and deeper understanding far further actions. This is a comparative study of inhabitants' life satisfaction in cohousing communities in Denmark and Sweden. The study is based on discussions with cohousing providers, study-visits in cohousing communities and a questionnaire to residents themselves. Study-visits took place during springtime and the questionnaires were handled spring and summer of 2002. 655 seniors responded to the questionnaire from 14 seniorbofae llesskaber (rented or housing cooperatives) in Denmark, 11 seniorhus within the SABO sector (municipality owned housing with rental apartments) and 8 housing cooperatives initiated by the Seniorgarden Housing Company in Sweden. Data were analyzed by SPSS program, using frequency, percentage, cross-tab and chi-square test. This paper focused three major areas of interest; 1)characteristics of the inhabitants. 2) participation in common activities and mutual cooperation among residents and 3) evaluative outcomes from the inhabitants' points of view. Mainly the inhabitants expressed quite positive experiences of their living environment and everyday lift and a few difference was found in life satisfaction between Denmark and Sweden.

With the prosperous economy, the status of diet and nutrition among the urban and rural Chinese population has been improved significantly. This paper will focuses on three main surveys in China. (1)'Food and Nutrition Surveillance System in China': Phase I focused on analysis of previous data. Phase II was a pilot survey initiated in Beijing, Hebei, Heilongjiang, Ningxia, Zhejiang, Guangzhou, and Sichuan in 1990. (2) 'The China Health and Nutrition Survey' is an ongoing longitudinal project covered 8(9) provinces in 1991,1993,1997,2000. This paper will analysis the adults aged 18 45 of 1991, 1993, 1997, and 2000. (3) Survey on the status of nutrition and health of the Chinese (2002) is an across sectional study covered 31 provinces, autonomous region and the municipalities. The data was used to analyze the status of food consumption and dietary nutrients intake of Chinese population. In the past ten years, the prevalence of malnutrition and nutrition deficiency has been continuously decreased. The consumptions of animal products, milk, and edible oil have been increased, while the dairy and legume products consumption decreased. The unbalance was showed with a downward trend in cereals, vegetables and fruits consumption and a significant increase in animal products and oil intake among urban people. Dietary pattern of some subjects went away to 'high energy density' diet. The deficiency of calcium, retinal and ascorbic acid etc, especially in the rural areas still exist. China is undergoing a remarkable, but undesirable, rapid transition towards a stage of the nutrition transition characterized by high rates of DR NCDs in a very short time. China is facing the dual challenges of nutrition deficiency and nutrition imbalance. The results can help to understand the dietary structure and the status of nutrition among Chinese people over the past years. It will provide the basis for formulating relevant state policies.

Geodetic Reference System was deferred from 2007 to 2010. Although National Geographic Information Institute in Korea takes charge of it, the progress is slow without clear policy alternatives. In this regards, this study aims at suggesting practical measures for introducing World Geodetic Reference System. Successful foreign countries have well established institutional system for improving their geodetic reference systems. In Korea, National Geographic Information Institute, Ministry of Maritime Affairs and Fisheries, and some municipalities have propelled introduction of the World Geodetic Reference System. However, none of them have systemical approaches. Although National Geographic Information Institute has conducted several researches regarding World Geodetic Reference System, comprehensive policy measures by central governments are not yet made. It suggests methods of data conversion, organizational structures, financial resources, and other supportive measures. Introduction of World Geodetic Reference System is nationwide project. However, there is not nationwide project promotion and management system yet. This research suggests overall policy frameworks to effectively propel World Geodetic Reference System.

In order to reduce the farmers' burden of purchasing agricultural machinery and address the shortage of farm workers, the government have been promoting agricultural machinery rental service since 2003. Despite of political purpose, the outcome of agricultural machinery rental service turned out to be adverse, high cost and low efficiency, by the pork barrel projects operated from some municipalities. Therefore, this study was aimed to improve the efficiency of agricultural machinery rental service by analyzing the operation status of agricultural machinery in local government. A questionnaire survey was conducted at 134 cities and counties in terms of rent type, management personnel, business budget, agricultural machinery ownership, rental performance, use rates, operational problems, and improvement plan. This study found that some agricultural machinery rental offices were only focused on the short-term rental service, which caused the increasing number of operating personnel, required facilities/equipment. The short-term rental service has a limitation for promoting the mechanization rate in dry-field farming. Therefore, it should be carried out along with the long-term rental service which a lessee maintains and manages agricultural machinery directly. Furthermore, the reasonable number of agricultural machinery based on regional circumstances should be considered to meet rental demand and collect the minimal rental fee for purchasing new agricultural machinery and replacing old ones.
