Recently, the social issues such as low birth rate, an aging population has brought about decreasing labor productivity and productive population. To relieve these problems, the government has planned to set up smart working infrastructure and will raise the number of smart worker to around 30 percent of the total working population by 2015. This study scrutinizes to the meaning of smart working with the concepts of new work pattern and open innovation. The empirical analysis result shows 56.9% of SMBs thought a need for such system and 60.1% of them answered to adopt it. And the market related to smart working of SMBs will increase to 17.5% every year to the point that by 2014. It will be worth 1.54 trillion won and create up to 38,000 job positions. While prior researches on SMB suggested key drivers and guideline for innovation, this study gives some implications of impact and ripple effect of smart working as an innovation factor based on empirical analysis.

The intergenerational transfer between parents and children is a major concern due to low birth rates and aging society of Korea. This study investigated the influences of children's support for parent regarding parents' decision to bequest, including the influences of parental characteristics, household-related factors, and characteristics of children. The data are the 5th wave of KReIS, a sample of 1,834 married household heads(HHs), which were classified into 142 baby boomers (1955-1963), 534 post-liberation HHs (1945-1954), and 1,158 Japanese-era HHs (-1945). The results were as follows: First, 49.3% of baby boomer HHs, 59.2% of post-liberation HHs, and 59.1% of Japanese-era HHs, were willing to make bequest decision. Second, in the baby boomer HHs, although the children's contact with their parents represented an emotional resource transfer, a child's economic resource transfer to his/her parents did not affect the parents' bequest decisions. However, in the post- liberation HHs, children's contact with parents, and economic resource transfers were significant variables. In addition, in the Japanese-era HHs, only children's contact with their parents was a significant variable. Third, in the baby boomer HHs, the variables that influenced parents' bequest decisions were household financial assets and having a daughter rather than having son and daughter. However, the variables that heavily influenced bequest decisions of the post-liberation HHs were the presence of a spouse, home ownership, household expenditures, and satisfaction of relationships with children. In the Japanese-era HHs, the variables that significantly affected parents' bequest decisions were home ownership, household expenditures, and household financial assets.

The sense of crisis regarding regional extinction due to low birth rates and an aging population is expanding. Generally, the local extinction index is used to analyze local extinction. However, it is challenging to diagnose the actual situation of village extinction risk in rural areas, even though the regional extinction index can be analyzed in units such as Si-Gun-Gu and Eup-Myeon-Dong. This difficulty arises because the regional extinction index solely relies on natural population growth indicators (elderly population and female population aged 20-39). Therefore, the purpose of this study is to develop a village extinction index that can identify the disappearance of rural villages. Additionally, the aim is to apply the developed indicators to the village (administrative ri) spatial unit. The existing regional extinction index used only mortality-related indicators as factors for natural population decline and fertility-related indicators as factors for natural population growth. However, the developed village extinction index included not only the factors of natural population change but also incorporated social population growth factors and factors related to the pace of village extinction. This is the key difference between the developed village extinction index and the existing regional extinction index. In this study, the indicators of "total population," "number of young women aged 20-44," "number of elderly population aged 70 or older," and "number of incoming population" were selected to develop a village extinction index. The village extinction index was developed by incorporating both natural population growth indicators and social population growth indicators. The developed village extinction index was applied to administrative villages. This research is expected to provide a more accurate understanding of the current state of rural villages facing extinction.

Massacres of civilians are being committed in the Russia-Ukraine war, and the war is becoming a long-term war due to a lack of support for reserve combat forces. Considering the reality that South Korea is experiencing a rapid population decline and is rapidly entering an aging society, we are at a point where the nature of the war with North Korea must change. Among them, if private security guards are placed under the control of the police as regular security and crime prevention personnel and used as an alternative resource for reserve forces to ensure the safety of wartime areas and residents and prepare for long-term wars, it will help preserve combat power and maintain sustainability.Regarding private security, considering Japan's further development, we compared it with ours and looked into ways to utilize it as a reserve force for a divided country. In a future where low birth rates will lead to a decrease in military strength, if private security guards are used in local security vacuums during peacetime and participate in local defense during wartime, it could help improve the Korean military's reserve force.

Recently, urban shrinkage due to low birth rate and aging population and the decline of local cities are causing a new urban problem of empty houses. This study examines the distribution of vacant homes using spatial panel data collected from 2015 to 2019 at local administraitve districts and estimates the factors of vacant house occurrence using a spatial panel model considering spatio-temporal dependency. As a result, the spatio-temporal dependence of vacant houses was identified and it was estimated using spatial panel model not OLS model. Based on the spatial panel model, it was found that the most influential factor in the occurrence of vacant houses was the housing-related factor. This result shows that policy considerations for housing supply are necessary for the management of vacant housing as well as population movement and poor infrastructure.

There is a serious risk of regional extinction due to low birth rate and aging in Korea. Accordingly, the regional extinction index is applied to diagnose the extinction status of cities, counties, and districts. However, when the regional extinction index was applied to rural villages, most villages were found to be at 'high risk of extinction'. There is no differentiation in the level of extinction of rural villages. Therefore, a village extinction index was developed to apply to rural villages. This study applies and compares the existing regional extinction index and the newly developed village extinction index to rural villages. The purpose is to propose an index that can better diagnose the extinction of rural villages. As a research method, the regional extinction index and village extinction index are applied to all villages in Haengjeong-ri villages in South Chungcheong Province. And the adequacy of the index suitable for rural villages is diagnosed. For this purpose, ➂ stage distribution for each two indices, ➂ demographic aspect diagnosis, and ➂ resident awareness survey were analyzed. When the village extinction index was used, the discrimination problems seen in the regional extinction index were overcome. As a result of the demographic analysis, the regional extinction index showed that villages with a population of 200 or more were at 'high risk of extinction', but the village extinction index was derived as 'high risk of extinction' for villages with underpopulated populations. Lastly, the results of the residents' awareness survey also showed that the village extinction index was well reflected in the actual situation of rural villages when applied. When the village extinction index was applied to rural villages rather than the regional extinction index, it was found to reflect the actual state of rural extinction better.

Nowadays, a 1-2 person household if increasing due to the aging population and the low birth rate. Thus, in August 2011, Seoul held the 'College Student's Idea Competition', which dealt with small but strong housing that has a very reasonable structure in spite of its small scale in order to improve the quality of small housing for a 1-2 person households. The study indicates the characteristic of this small housing in order to target competition entries from college students; 93- works have been processed. First, the properties of residents are investigated through the number of household members and the relations of the residents. To ensure various element techniques of the entries, the study analyzes data via a structured analysis. Along with structured element techniques according to each level, eight element techniques of the furniture level, housing unit level, main building, and district-level are derived. This study suggests various element techniques in response to the efficiency of area in households as well as housing unit levels. Plans of public spaces and community life housing are offered at the level of the main building and at the district-level. Through an analysis of competition, the critical point of small house planning in deliberation is not only about space and economic efficiency of physical unit, but the life of the residents.

Research for efficient management of the National Pension has been emphasized as the current society trends toward aging and low birth rate. In this article, we suggest a statistical model for effective classification and prediction of the reserve for the survivor's pension in Korea. Logistic regression model is incorporated; correct classification rate, and distribution of the posterior probability for the reserve of survivor's pension are investigated and compared with the results from the general logistic models. Assessment of predictive model is also done with lift graph, ROC curve and K-S statistic. We suggest strategies for reducing financial risks in managing and planning the pension as an application of the suggested model.

Demands for housing has diversified recently due to low birth rate and the growth of aging population. Also, a share of idle houses and obsolete houses over 20 years old is gradually rising. Therefore, there is a need for a sustainable, environment-friendly improvement policy that is in line with a new housing paradigm and avoids full-scale new construction, such as a customized housing renovation plan considering local economic circumstances. Therefore, afforestation system applicable to buildings are assessed positively, but lack objective performance evaluation. Through one-year, long-term monitoring of replicated obsolete buildings that have poor insulation performance, this study calculated monthly average power consumption and analyzed power charges by applying pricing plans before and after the revision of progressive tax in order to examine economic effects expected by applying the afforestation system. In the obsolete buildings, the study showed that monthly average power consumption was reduced by 16.6kWh with 5.2% average reduction rate. Highest reduction was made in July at 11.3%. Aggregate monthly power consumption charges were relatively high in winter before and after the revision of progressive tax. Power charges reduction effect was highest in March when monthly power consumption was reduced to 300kWh level by applying the afforestation system.

Japan has generally been considered as the developmentalist welfare state. However, Japan has recently been transformed into a social investment state. Although it still has a developmentalist characteristics with its institutional path dependence, the new social and economic challenges derived from the new social risks such as low birth rates and aging population forced Japan to adopt a new welfare state strategy. The paradigm shift in terms of welfare state strategy was launched by the Third Way positioning of the Democratic party government and succeed to the Second Stage of Abenomics under the Third Abe Cabinet. This paper argues that the welfare state paradigm shift towards a social investment state in Japan is not limited to the Japan's Plan for Dynamic Engagement of All Citizens for a virtuous cycle of growth and distribution, but expands its scope to include the work-family balance policies such as labor market activation for women and public caring for children.
