Forecasting the electricity consumption through analyzing the past electricity consumption a advantageous for energy planing and policy. Machine learning is widely used as a method to predict electricity consumption. Among them, ensemble learning is a method to avoid the overfitting of models and reduce variance to improve prediction accuracy. However, ensemble learning applied to daily data shows the disadvantages of predicting a center value without showing a peak due to the characteristics of ensemble learning. In this study, we overcome the shortcomings of ensemble learning by considering the temperature trend. We compare nine models and propose a model using random forest with the linear trend of temperature.

Even after three decades of economic reforms, India's labor market is characterized by stark inter-gender differences in terms of both participation rate and working time. Identification of the causes is necessary to remove the disparity and unequal sharing of economic opportunities to make way for women's empowerment. This research attempts in that direction, examining the prevalence of these inequities in rural areas of North-East Indian states using unit-level data from the 2017-18 Periodic Labour Force Survey (PLFS). The methodology for the estimation here is based on Blinder- Oaxaca decomposition method after correcting for sample bias forwarded by Heckman. The analysis shows that in both labor force participation and the wage gap, the females in the region lag behind their male counterparts by a huge margin. Further, the analysis shows that one of the main factors leading to the difference is the disparities in human capital assets. On top of female educational enrollment being low, there is also a huge lack of higher educational attainment, while males have accomplished much better in both the parameters. Moreover, the presence of social stigma against women working and discrimination put the female labor outcomes in a gloomy state.

The Purpose of this research is to draw implications of Multi-Functions of social welfare facilities on non-public social welfare delivery system especially in the rural area where there is not enough welfare infrastructure. The policy formation process of social welfare facilities was reviewed with 'Modified Policy Streams Framework" which combined Kingdon's Model with Mucciaroni's Model. Multi-Functions Policy of Social Welfare Facilities was led by the government with background of powerful President's initial stage of taking the power and finally legislated by amending Social Welfare Service Act in line with efficiency of non-public social welfare delivery system. However, the process did not represent the summation of needs originated from social work practice. The government just play the role of collecting some evidence underpinning the necessity of multi-functions of social welfare facilities and rearanging how to deploy the multi-functions policy. As the result the multi-functions policy is not activated and is not able to be the key criteria in expanding social welfare infrastructure. However, in spite of these limitation, the issue of multi-functions of social welfare facilities can cast the light on expanding infrastructure in the rural area where the gross size of area in larger in comparison to the district in the metropolitan city whereas residents are scattered because more number of social welfare facilities can not be the solution due to the limitation of finance and logic of efficiency.

Objectives: To investigate the patterns of unintentional home injuries in Korea. Methods: The study population was 12,382,088 people who utilized National Health Insurance services due to injuries (main diagnosis codes S00 to T28) during 2006. Stratified samples(n=459,501) were randomly selected by sex, age group and severity of injury. A questionnaire was developed based on the International Classification of External Causes of Injury and 18,000 cases surveyed by telephone were analyzed after being projected into population proportionately according to the response rates of their strata. Domestic injury cases were finally included. Results: Domestic injuries (n=3,804) comprised 21.1% of total daily life injuries during 2006. Women were vulnerable to home injuries, with the elderly and those of lower income (medical-aid users) tending to suffer more severe injuries. Injury occurred most often due to a slipping fall (33.9%), overexertion (15.3%), falling (9.5%) and stumbling (9.4%), with severe injury most often resulting from slipping falls, falls and stumbles. Increasing age correlated with domestic injury-related disability. Conclusions: The present findings provide basic information for development of home injury prevention strategies, with focus on the elderly.

Objectives: Agent Orange TCDD has been related to serious diseases among Korean veterans who were exposed to it. Decades after the end of the war, however, its effects are still being debated. The object of this study was to examine various unmet needs raised among Agent Orange exposed veterans and their families and to find grounds of a new welfare policy for providing alternative legislation. Methods: Literatures concerning Agent Orange, TCDD, the associated diseases, compensation for veterans and Supreme Court sentencing were searched using PubMed, ProQuest, press news and relevant homepages. Results: Agent Orange exposed veterans are eligible for various benefits from the government, including disability compensation for diseases associated with exposure. The Ministry of Patriots and Veterans Affairs has classified certain diseases into two categories, Agent Orange sequela diseases and sequela suspect diseases and has provided differential benefits based on separated laws. Big differences exist in benefits to veterans and their families between the two laws. The absence of definite standards to classify the Agent Orange associated diseases was confirmed by recent Supreme Court sentencing which ruled in favor of US manufacturers. Conclusion: It appears that the evidence for cause and effect of Agent Orange related diseases would never be perfect. The results suggest a need to change welfare principles from presumptive or indefinite disease basis to exposure experiences combined with integrated disability evaluation. We propose to extend eligibility by enacting a new law for Agent Orange exposed Korean veterans.

How would people who buy an insurance policy respond to a low probability risk with a high future cost? Presented with a scenario describing a low probability accident of a chemical plant, participants in four experiments were asked to rate their perception of the risk and also their intention to buy an insurance of a given premium, an insurance, or a ratio insurance. Participants differently responded only to ratio insurance when rating their perception of risk, not to either premium or insurance. The pattern of results in four experiments converged to the conclusion that ratio insurance, an ecologically valid cue, makes people sensitive to the level of risk expressed in low probabilities of an accident. Our results were consistent with the prediction generated by the ecological cue hypothesis which empathizes the importance of frequency over probability in risk perception (Gigerenzer, 2000).

Many saeteomins to settle in South Korea, are materially affluent capitalist countries entered South Korea, but they have not been able to adapt so easily the consumer market and economic activity. In particular, development and support training programs for female saeteomins, 69% of total saeteomins are needed. Therefore, we need to support job programs that they settle in Korea normally and can be a reasonable economic activity. But, we need to operate be the group program because only proceed to the general education program is not enough to settle into a stable. In this paper, we would like to propose a group program for job training and a budget for operating the program to easily settle female saeteomins in South Korea.

This kind of goal orientation in Art Nouveau has provided nature-friendly designs to modern people living in a post-industrial society. For these people who want to have their own style in a natural and comfortable space and take a break from daily hectic daily routines for a moment, hair-by-night styles were created by adding the images of Greek goddesses to the nature-friendly features of Art Nouveau patterns known as 'flower pattern', 'wave pattern', and 'vine pattern'. In terms of the scope of this paper, four designs (Eos, Hestia, Artemis and Demeter) were created by using Art Nouveau patterns which are connected with flowers in an organic manner based on Rene Lalique and Emile Galle patterns.
