Active attention and effort are needed to develop an integrated water management system in response to climate change. In this study, it proposed models for cross-use of agricultural water and river maintenance water using sewage treatment water as an integrated water management system for the Yeongsan River. The impact of the integrated water management models was assessed by applying the concept of Nexus, which is being presented worldwide for sustainable resource management. The target year was set for 2030 and quantitatively analyzed water, energy, land use and carbon emissions and resource availability index by integrated water management models was calculated by applying maximum usable amount by resource. An integrated water management system evaluation model using the Nexus concept developed in this study can play a role that can be viewed in a variety of ways: security and environmental impact assessment of other resources. The results of this research will be used as a foundation for the field of in the establishment of a policy decision support system to evaluate various security policies, as we analyzed changes in other factors according to changes in individual components, taking into account the associations between water, energy, food, and carbon resources. In future studies, additional sub-models need to be built that can be applied flexibly to changes in the future timing of the inter-resource relationship components.

For the past few years, the Korean government has been consistently expanding its national research & development budget to accelerate economic growth through technology innovation and the enhancement of international competitiveness in global markets. The objective of this paper is to define the concept and analyze the current status of national R&D programs by measuring R&D efficiencies. We determine R&D efficiency by reflecting inputs and outcomes of the five main agricultural R&D programs between 2010 to 2015, and by categorizing and regrouping figures that may affect R&D performance. Among 1,128 targeted projects, 832 projects with patents and thesis were selected for analysis in terms of measuring technology efficiency, pure technology efficiency, and efficiency of scale. Also, the Kruskal-Wallis test was also utilized as well. As a result of empirical analysis, figures that affected the efficiency level of national R&D programs included differences in research resources, research management levels and skills, and research field. This study can be utilized as a reference for re-establishing national agricultural R&D policies, such as enhancement of national technology competitiveness in the global market environment, improving and adapting to new agricultural conditions, market expansion, national agricultural R&D efficiency, aging rural population, agricultural management cost increase, and climate change mitigation.

This paper is aimed to analyse the recent changes in family planning as a step in an evaluation of the results of the population control policy which has been strenuously pursued by the government since December 1981. The data used in this analysis comes from the 1985 national fertility and family planning survey conducted by the Korea Institute for Population and Health (KIPH) in May 1985. According to the 1985 survey data, there have been great changes in both the contraceptive practice and fertility rates since the strengthening of the government's population control policy in 1 981. The contraceptive practice rate for married women aged 15-44 has increased from 57.7% in 1982 to 70.3% in 1985, an increase of 12.6% points in the short span of only 3 years. During the same period, the total fertility rate has declined from 2.7 in 1982 to the population replacement level which was planned to achieve by 1 988. More than 80% of women aged over 30 or with two children or more are practicing contraception, while the practice rates of women with 0-1 children are 14.0% and 45.1% respectively. The survey has revealed that the increase of contraceptive practice rate during 1982-1985 has mainly attributed to the high acceptance of sterilization procedures which practice rate of the married women has increased from 28.1% to 40.3% for the period. Also, the survey data shows that 24.7% of those women with only one child is practicing contraception for thepurpose of fertility termination. The government, taking into account of rapid changes in contraceptive practice and fertility rates, is formulating a population plan during the sixth fiveyear economic and social development plan (1987-1991) to achieve 1% ofpopulation growth rate by 1993, which was planned to realize by 2000. In order to meet this demographic goal, the existing population control policy measures should be improved to be suited to the recent contraceptive use and fertility changes. From this standpoint, the following considerations should be put forth; 1) improvement of the current program management systems including target allocation and evaluation schems for recruiting new acceptors in the young 20s groups to use contraceptives for birth spacing and to increase high continuation rates through the strengthening of follow-up services for the acceptors, 2) increase of self-supporting contraceptive users by promoting commercial advertisements on contraceptives through mass media including T.V. and radio, 3) development of social support policies including incentive schems, and strengthening of IE & C activities for increasing the proportion of the one-child family, 4) strengthening of population and family planning education in and out school youth, and 5) strengthening of management capabilities at the provincial and local program managers.

토지이용의 전환에 따른 기후의 변화와 토지가격의 변화를 파악하는 것은 도시민의 후생수준과 지속가능한 개발을 위해 매우 중요한 과제이다. 그러나 도시특성에 관한 정보가 부족하여 활발하게 연구되지 못하였다. 이제 원격탐사를 통한 위성영상의 구득이 쉬워졌고 또 통계청이 기초단위구 자료를 구축함에 따라 이 분야의 연구가 가능하게 되었다. 본 연구는 도시지역의 비도시용 토지가 도시적 용도로 전환됨에 따라 표면온도와 토지가격의 측면에서 어떠한 변화를 유발하는가를 분석하였다. 분석결과 녹지 및 농경지로 사용되던 토지가 공업용토지로 전환된 경우 가장 큰 표면온도의 상승을 초래하였고 상업용지와 단독주택지가 그 뒤를 이었다. 식생지수의 변화도 표면온도의 변화와 비슷한 변화를 보였다. 토지가격의 전환측면에서는 상업용토지로 전환될 경우 가장 큰 가격상승을 초래하였고 그 뒤를 이어 주거지 공업용지의 순으로 나타났다. 이처럼 도시지역의 토지이용의 전환은 표면온도를 상승시킬 뿐 아니라 토지가격도 상승시켜 사회적 부담을 주지만 그 혜택은 사회구성원 중 극히 일부에 한정되는 문제가 있다. 도시정책과 관련된 정책결정권자 및 계획가는 이 문제의 해결을 위해 도시성장관리 정책의 확립 등 보다 효과적인 정책수단을 강구하여야 할 것이다.

Currently serious conflicts of interests are arisen for the use of coastal area in Korea. However, there no mediation program, mediators' consistent policies and reasonable laws to resolve conflict of interests which may be arisen when developing coastal area. The objective of this study is to lay the evaluation criteria for the formalized objective evaluation among disputants of coastal conflicts for the better understanding and characterizing of coastal conflicts in Korea. In order to do so, this study has adopted for the extraction of the evaluation factors to describe the present conditions of conflicts in the selected study area(Sihwa lake), to analyze the problems, and then to explore alternative approaches for resolving the conflicts. As research methodologies, we have depended upon literature review and field survey methods. As field survey methods, we employed structured questionnaires for the various samples from the experts of research institutes, professors, representatives of NGOs and citizens. Survey results suggested that 5 representative elements comprising 35 detailed elements could be identified. Based on these results, this study was able to identify and classify the evaluation factors and help to resolve coastal conflicts in Korea.

The intensity of stormwater runoff is particularly acute across cities located in arid climates. During flash floods loose sediment and pollutants are typically transported across sun-hardened surfaces contributing to widespread degradation of water quality. Rapid, dense urbanization exacerbates the problem by creating continuous areas of impervious surfaces, perforated only by a few green patches. Our work demonstrates how the latest techniques in remote sensing can be used to routinely measure urban land cover types, impervious cover, and vegetated areas. In addition, multiple regression models can then infer relationships between urban land use and land cover types with stormwater quality data, initially sampled at discrete monitoring sites, and then extrapolated annually across an arid city; in our case, the city of Phoenix in Arizona, USA. Results reveal that from 30 storm event samples, solids and heavy metal pollutants were found to be highly related with general impervious surfaces; in particular, with industrial and commercial land use types. Repercussions stemming from this work include support for public policies that advocate environmental sustainability and the more recent focus on urban livability. Also, advocacy for new urban construction and re-development that both steer away from vast unbroken impervious surfaces, in place of more fragmented landscapes that harmonize built and green spaces.

Agricultural meteorological information is an important resource that affects farmers' income, food security, and agricultural conditions. Thus, such data are used in various fields that are responsible for planning, enforcing, and evaluating agricultural policies. The meteorological information obtained from automatic weather observation systems operated by rural development agencies contains missing values owing to temporary mechanical or communication deficiencies. It is known that missing values lead to reduction in the reliability and validity of the model. In this study, the hierarchical Bayesian spatio-temporal model suggests replacements for missing values because the meteorological information includes spatio-temporal correlation. The prior distribution is very important in the Bayesian approach. However, we found a problem where the spatial decay parameter was not converged through the trace plot. A suitable spatial decay parameter, estimated on the bias of root-mean-square error (RMSE), which was determined to be the difference between the predicted and observed values. The latitude, longitude, and altitude were considered as covariates. The estimated spatial decay parameters were 0.041 and 0.039, for the spatio-temporal model with latitude and longitude and for latitude, longitude, and altitude, respectively. The posterior distributions were stable after the spatial decay parameter was fixed. root mean square error (RMSE), mean absolute error (MAE), mean absolute percentage error (MAPE), and bias were calculated for model validation. Finally, the missing values were generated using the independent Gaussian process model.

The condition of financial services in Indonesia is unique, based on various characteristics, behaviors, and preferences. Therefore, the study of finance and banking is interesting to study as a recommendation for government policies. This paper aims to analyze the barriers to accessing formal financial services in Indonesia and why informal financial services are preferred. This paper presents a case study of financial inclusion in selected provinces in Indonesia using the SOFIA dataset from the Ministry of National Development Planning. Overall, this data consists of 20,000 individuals from 4 provinces and 93 regions representing the population in eastern Indonesia. The analysis was carried out by processing individual-level cross-sectional data surveyed in 2017 using the probit binary logistic method. The results identify the individual barriers in accessing formal financial services, including account ownership, saving, and credit activities in the formal financial institutions, and amplify the image by analyzing what determinants affect people to choose informal institutions. We found that some individual characteristics such as age, gender, education, income, employment status, residence, and access to technology significantly affect the barrier to formal financial services in East Indonesia.

Purpose: This paper aims to clarify the concept of well-dying in the sociocultural context of Korea. Methods: Walker and Avant's method was chosen for the concept analysis. Through a literature review of 36 papers, the attributes and definition of well-dying were derived. Results: The literature revealed that in Korean society, well-dying is defined as the process of actively preparing for death throughout life. The attributes of the concept are a reflection on death, death acceptance, searching for meaning, transcendence, advance decision-making, and sharing values with family. The motivation for thinking about death, the hope of dying with dignity, and the Korean cultural view of death precede the concept, followed by dying with dignity, personal and family happiness, and improved quality of life and death. Conclusion: This study may lead to the unification of concept use based on mutual understanding, thus enabling effective communication in research, education, and clinical settings. This can be the rationale for the development of tools and educational programs as well as establishing policies related to well-dying in Korea.
