The purpose of this study is to interpret the growth and the present status of in 6 major Korean cities and 9 provinces libraries using statistical data. The data were collected from The Statistics on Libraries in Korea, and were analyzed for a time series by using the Excel program. The result shows that there are great differences in major statistics of libraries in Korea due to the historical backgrounds and various political and social conditions of the country. The differences are also more likely related to the size of the library collections, budget and number of staffs.

The purpose of this study is to investigate the characteristics of the elderly based on the types of Kyungrodang participation and explores ways toward development of Kyungrodang. A national sample data, collected by the Korean Institute for the Health and Social Welfare in 2004 is analyzed by employing Chi-Square test of independence, ANOVA, and multiple logistic regression(n=3,005). A significant difference is noted in age, area, and socioeconomic status among the elderly based on the types of Kyungrodang participation. The results show that those elderly living in rural areas with older and lower socioeconomic status are more likely to participate at Kyungrodang, whereas, elderly living in urban areas with younger and higher socioeconomic status are less likely to participate at Kyungrodang and discontinue to use the services. Although there is a difference between the gender, the most significant reason for not using and discontinuing Kyungrodang is because the elderly can not get along with the other participants. In other words, the major problem that needs to be solved is to socializing and providing service programs satisfying all participants. Based on the results and recent socioeconomic changes of the older population, some policy issues are suggested for the development of Kyungrodang.

This study investigated intake frequency and opinions regarding native local foods in school foodservice and compared eating status between students in Gyeongsang-do and Jeolla-do. Questionnaires were distributed to 300 students at elementary schools located in Gyeongsang-do and Jeolla-do. The results of this study were as follows. First, intake frequencies of Gyeongsang-do-native local foods by students in Gyeongsang-do was significantly higher than compared to students in Jeolla-do (P<0.01). Second, there was no significant difference in concern for native local foods between students in Gyeongsang-do and students in Jeolla-do, although opinions regarding native local foods in school foodservice by students in Gyeongsang-do were higher compared to students in Jeolla-do (P<0.01). In conclusion, there was a regional difference in terms of intake frequency of Gyeongsang-do-native local foods, whereas there was no regional difference in terms of intake frequency of Jeolla-do-native local food. Students in Gyeongsang-do showed more positive attitudes regarding native local foods in school foodservice than students in Jeolla-do. This result implies that regional differences between Gyeongsang-do and Jeolla-do regarding native local foods should be removed. In order to develop native local foods, it will be necessary to develop a program to actively apply native local foods in school foodservice and provide more chances for elementary school students to experience various native local foods.

A pre-feasibility test is done for renewable energy hybrid power systems at off~grid islands in which the current power supply is provided only by diesel generation. We apply Homer (Hybrid Optimization Model for Electric Renewables) which was developed by the National Renewable Energy Laboratory (NREL) for the analysis to identify the cost-minimizing combination of power generating facilities for the given load profiles. Chuja-Do, Geomun-Do and Youngsan-Do have been selected for our analysis considering the wind resources data of the Korea Institute of Energy Research (KIER). Information on wind speed, solar radiation and temperature is also used for the analysis. System component cost information from overseas market has been used due to the lack of domestic information. Site specific Load profile for electricity demand for those islands are reconstructed based on the partial survey results obtained form other sources. The LCOE of the least cost hybrid power systems for Chuja-Do, Geomun-Do and Youngsan-Do are $0.278/kWh, $0.234/kWh and $0.353/kWh, respectively Considering the fact that diesel generation is being subsidized at the price of $0.300/kWh by the government, first 2 cases are economically feasible for the introduction of renewable energy hybrid systems to those islands. But the third case of Youngsan-Do does not meet the criteria. The basic differences of these pre-feasibility test results are from the differences of the site specific renewable energy conditions, especially wind resources. In summary, promoting hybrid systems in the off-grid remote island should be based on the economic feasibility test results. Not all the off-grid islands are feasible for introducing this renewable energy hybrid system.

한국은 2050년까지 주요 선진국 중에서 고령화가 가장 심각한 사회로 전환되게 될 것으로 예상된다. 기대여명의 증가와 저 출산은 고령화를 더욱 악화시키며, 이는 심각한 사회문제로 발전하게 될 것이다. 이와 같은 문제를 해결하기 위해 한국정부는 2008년에 도시지역에는 주택연금제도를 도입하였으며, 2011년에는 세계 최초로 농촌지역을 대상으로 농지연금제도를 도입하였다. 그렇지만 이와 같은 제도는 설계 당시부터 복지상품이라기 보다는 장기적으로 손실과 수익의 균형에 초점을 둔 금융상품으로 개발되어 실질적으로 노인들에게 크게 인기를 얻지 못하였다. 따라서 본 연구는 농지연금제도를 활성화시켜, 농촌노인들에게 보다 더 많은 혜택을 주기 위해 지역 토지시장을 감안하여 지역별 농지가격상승률을 예측하고 연금액을 산출하였다. 또, 지금까지 사용한 년 혹은 분기별 감정가 대신에 월별, 지역별 실거래 가격을 모형에 적용하여 지역토지시장, 고령화 수준 등 지역 여건에 부합하는 연금액을 산출하였다. 할인율자료도 가장 안정적인 3년 만기 국고채 수익률을 활용하여 미래농지가격을 예측하고, 이를 유동화하여 월 생활자금으로 지급되도록 하였다. 특히 농지규모가 가장 많고, 고령화 정도가 심각하여 농지연금의 잠재적 수요가 가장 높을 것으로 예상되는 경상북도와 전라남도를 사례지역으로 선정하고, 이를 전국평균과 비교하여 지역적인 차이도 함께 분석하였다. 이를 위해 농지가격 및 이자율 시계열 자료의 안정성을 검정하고, 장기농지가격을 예측하였다. 이를 활용하여 경북, 전남, 전국의 노인들의 월평균 지급액을 추정하였다. 분석결과 정책의 잠재적 수요가 가장 높은 두 지역이 가장 낮은 금액이 지급되는 것으로 추정되어 이는 또 다른 지역불균형을 초래할 수 있는 것으로 평가되었다.

The purpose of this study is to compare the differences in the subjective quality of life (QoL) perceived by residents in different settlement spaces such as urban vs. rural and Seoul Capital Area (SCA) vs. Non-Capital Area (NCA). Using the data of the 'Quality of Life Satisfaction Survey for Balanced Development' conducted nationwide by the Presidential Committee for Balanced National Development in 2018, a propensity score matching method was introduced to compare the differences between the types of settlement spaces. The results show that no significant difference is found between all the types in satisfaction with local life, and in the case of happiness, rural residents show a higher level than those living in cities. Looking at the quality of life by QoL domain, the QoL of urban residents in SCA is generally the highest in the basic living environment, medical care, and culture/leisure domains, while the QoL of rural residents in the job/income, environment, community, and welfare domains is higher than that of residents of SCA and NCA cities. Interestingly, in no domains NCA cities show their relative strength. These results show the value of rural areas in the face of increasingly prevailing urbanization trends, and suggests that the value of rural areas must be strengthened for rural development. It is necessary to pursue policy efforts such as rural regeneration based on spatial planning in order to respond to the disorganized development that damages the value of the rural environment and landscape and to harmoniously maintain and develop the rural settlement.

This paper examines if China' each province.city manages its organization well after China's WTO affiliation; and on the ground, judges how much each province city needs to improve. China's each province city data from 2002 to 2006 is used to evaluate technical efficiency by using the input-oriented CCR model and the input-oriented BCC model. Analytical results show that only Shanghai gets continuously the highest efficiency score from 2002 to 2006 and so the other provinces cities need to benchmark Shanghai to elevate their efficiency. There can be regional, cultural and emotional differences among the provinces cities but Tibet, Shaanxi, Gansu, Qinghai, Ningxia and Xinjiang get low efficiency scores even after China's WTO affiliation. The Chinese government can make use of efficiency evaluation results by DEA as basic materials in making economic development schemes in order to reduce these deviations as various minority races constitutes China and there are regional deviations of degree of economic development in China.
