Combining power generation and water production by desalination is economically advantageous. Most desalination projects use fossil fuels as an energy source, and thus contribute to increased levels of greenhouse gases. Environmental concerns have spurred researchers to find new sources of energy for desalination plants. The coupling of nuclear power production with desalination is one of the best options to achieve growth with lower environmental impact. In this paper, we will per-form a sensitivity study of coupling nuclear power to various combinations of desalination technology: {1} thermal (MSF [Multi-Stage Flashing], MED [Multi-Effect Distillation], and MED-TVC [Multi-Effect Distillation with Thermal Vapour Compression]); {2} membrane RO [Reverse Osmosis]; and {3} hybrid (MSF-RO [Multi-Stage Flashing & Reverse Osmosis] and MED-RO [Multi-Effect Distillation & Reverse Osmosis]). The Korean designed reactor plant, the APR1400 will be modeled as the energy production facility. The economical evaluation will then be executed using the computer program DEEP (Desalination Economic Evaluation Program) as developed by the IAEA. The program has capabilities to model several types of nuclear and fossil power plants, nuclear and fossil heat sources, and thermal distillation and membrane desalination technologies. The output of DEEP includes levelized water and power costs, breakdowns of cost components, energy consumption, and net saleable power for any selected option. In this study, we will examine the APR1400 coupled with a desalination power plant in the Kingdom of Saudi Arabia (KSA) as a prototypical example. The KSA currently has approximately 20% of the installed worldwide capacity for seawater desalination. Utilities such as power and water are constructed and run by the government. Per state practice, economic evaluation for these utilities do not consider or apply interest or carrying cost. Therefore, in this paper the evaluation results will be based on two scenarios. The first one assumes the water utility is under direct government control and in this case the interest and discount rate will be set to zero. The second scenario will assume that the water utility is controlled by a private enterprise and in this case we will consider different values of interest and discount rates (4%, 8%, & 12%).

본 연구는 재정패널을 이용하여 공무원연금 납부 가구의 경제행태를 국민연금 가구와 비교하여 분석하였다. 첫째, 공무원연금 가구의 소득은 국민연금 가구보다 평균적으로 높다. 둘째, 공무원연금 가구 순자산은 국민연금 가구보다 현격히 작다. 이는 공무원연금의 저축구축효과 뿐만 아니라 비공무원 가구의 상속자산이 공무원연금 가구보다 높은 데에서 기인할 수 있다. 셋째, 공무원연금 가구의 월 소비 지출은 국민연금 가구보다 유의하게 높다. 기초통계량 분석과 고정효과분석을 통하여 공무원연금 가구 효과가 유의하게 존재함을 볼 수 있다. 공무원연금 가구의 순자산이 작고 월 소비 지출이 큰 이유는 해당 가구가 안정적이고 지급률이 높은 공무원연금소득을 기대하고 있기 때문에 저축의 필요성을 덜 느끼기 때문이라고 해석할 수 있다.

본 연구논문은 IMF 경제위기가 우리의 가족생활에 미친 영향을 살펴보았다. 경제위기가 가져온 생활수준의 변화와 경제적 고통의 내용과 함께 가족간의 접촉의 정도나 가족폭력, 가족해체 등 가족관계에 일어난 변화를 살펴보았다. 또한 친족 친지와 주고받은 경제적 도움의 정도나 소비지출행동의 변화를 통해서 완만한 사회변화 과정에서는 잘 드러나지 않았던 한국 가족의 특성 및 가족생활의 단면을 살펴 보았다. 뿐만아니라 경제위기가 장차 성별관계에 미칠 영향을 여성들의 취업동기의 강화나 역할행동의 변화라는 관점에서 검토해 보았다. 경제위기는 가족관계에 변화를 가져왔다. 전체적으로 실업이 생긴 가족들은 가족관계에 무엇인가 달라졌다고 느낀 경우가 많았고, 긍정적으로든 부정적으로든 부부 간의 접촉빈도가 높아졌다. 부부간의 폭력이나 해체의 가능성이 비교적 낮게 나타난 반면, 자녀에 대한 폭력이 이보다 직접적으로 반영되었다. 사회적 보장제도나 친구에 비해서 친족은 여전히 가장 중요한 경제적 의지의 대상으로 존재하고 인다는 사실도 확인되었다. 특히 친정이 도움의 자원으로 활용되고 있다는 점은 주목할 만하다. 이러한 사실들은 기존의 서구사회를 대상으로 한 조사결과들과 다소 다른 것들이므로, 우리사회를 해석하는 중요한 자료가 될 수 있을 것이다. 뿐만 아니라, 경제위기의 소비 변화를 통해서 우리사회에서 문화비용과, 병원비. 그리고 사교육비가 지출의 신축성을 가진 부분인 것이 드러났다. 그리고 경제위기에 직면하여 여성들의 취업에서 경제적 동기가 강화되는 측면과 함께 역할행동의 변화가능성도 일부 제시되었다.

The purpose of the study is to microscopically re-clarify the reality of renovation and conflicts that females faced within their families since the modernization period. The research method is the literature review. Families have been considered based on the formation of individual spaces for housing by husband and wife. The study will analyze changes in daily lives and housing consciousness to understand how such housing areas are transforming. The results of the study are as follows. From the perspective of symbolic interaction, in a traditional society, Korean females have been experiencing alienation and isolation in private areas in their daily lives due to family centrism and male chauvinism. Since industrialization, the female's role as the major consumer has been emphasized. Also, in terms of housing space, the symbol of family interaction was influenced more by utility, rationality, and equality than spatial hierarchy. From the perspective of the dailiness of phenomenological traditions, the modern girl's housing consciousness, which appeared during modernization under colonial rule, is considered as revolutionary from traditional society. Soon after in industrialized society, females appeared as leaders of 'sweet home'. They also became the main body to create the space for living by giving meaning to the interior of housing. Considering dailiness from the Marxist perspective, under the colonial social system, females became the subject of colonization through education, socialization, and the labor market. The modern public system presents the female as 'a wise mom and good wife' or laborer causing the colonization of her life. After industrialization, the socialization of housing and prioritization of spending caused the daily lives of females to become colonized by the consumption market.

Background: Cancer is one of the leading causes of death in Korea. To reduce cancer incidence, the Korean National Cancer Center (KNCC) has been expanding its organized cancer screening program. In addition, there are opportunistic screening programs that can be chosen by individuals or their healthcare providers. The purpose of this study was to investigate factors associated with participation in organized and opportunistic cancer screening programs, with a particular focus on socioeconomic factors. Materials and Methods: We used data from the Korea National Health and Nutrition Examination Survey (KNHANES), a cross-sectional nationwide study conducted by the Korean Ministry of Health and Welfare from 2007 to 2011. The study included information from 9,708 men and 12,739 women aged 19 years or over. Multinomial logistic regression analysis was conducted, adjusting for age, year of data collection, residential region, current smoking status, current alcohol consumption status, exercise, marriage status, job status, perceived health status, stress level, BMI, limitation of activities, cancer history, health insurance type, and private insurance status, to investigate the association between education level, economic status, and cancer screening participation. Results: In terms of education level, disparities in attendance were observed only for the opportunistic screening program. In contrast, there was no association between education level and participation in organized screening. In terms of economic status, disparities in opportunistic screening participation were observed at all income levels, but disparities in organized screening participation were observed only at the highest income level. Conclusions: Our findings reveal that socioeconomic factors, including educational level and economic status, were not significantly associated with participation in organized cancer screening, except at the highest level of income.

Fishing village is becoming the central base of fishing industry and it plays a major role. However, there is a decrement of marine resources and some difficulties with the deterioration of fishing industry management. In order to solve these problems, there should be some developments(e.g. fishing village toursim development) on various undergoing government and the private organization programs. Nevertheless, there are not guidelines for fishing village tourism development to utilize for practical business. Therefore, it is necessary to understand the current status and guidelines regarding the development of fishing village for coastal planner. The primary purpose of this study is to investigate the characteristics of fishing village development works in Korea and Japan. The second purpose is to identifie success factors after analyzing individual success cases. Based on evidence from the literature and a dialogue with village leader, a literature review on extracting success cases for guidelines were selected according to criteria such as the degree of contribution to an increase in income of the fishing village, the degree of contribution to an increase in consumption of marine products using local natural resources, the number of tourists that visits the village. Finally we propose guidelines for future fishing village development projects. The guidelines based on the successful cases, as well as the major factors about the objectives and direction of fishing village tourism development, suggested as follows. 1)Plans for land use, 2)Development of tourist resources, 3)Plans for views, 4)Plans for resource protection, 5)Plans for operation and marketing.

This study analyzes the motives of Korean women for choosing breast augmentation in a cultural and relational context; in addition, it investigates their evaluations after surgery. Data was collected through in-depth interviews with 10 Korean women in their 20s and 30s who have received cosmetic breast augmentation. Enlarged and made-up breasts are a form of clothing that symbolizes the socio-economic status of women. In the vertical and individualized Korean society, the desire of women for a fashionable body invigorated the appearance management market. Fashion consumers have passively internalized the ideal body trends as the concept of the ideal body-image, which has been constructed by the social structure, markets, and the media. The analysis was rooted in post-modern feminist perspectives on the female body. The ideal body-image internalization process through the social interactions of participants was the main cultural factor to choose breast surgery. The self-image and conformity/individuality of participant were categorized as relational factors for the motivation to undergo breast surgery. The result showed that after surgery the participants achieved positive feedback from their social relationships. They expressed or hid their socio-economic statuses through their purchased fashion bodies. They also showed higher self-esteem and feelings of satisfaction by pursuing individuality and conformity as a member of society. Moreover, they achieved wider fashion options and greater controls over their public/private/secret clothing choices for certain occasions. Cosmetic breast surgery positively empowered individual women while reinforcing the socially manipulated body ideals that oppress women at the same time. Participants internalized socially constructed values and justified their surgery choices.

In Korea, small-scale reclaimed areas have been suffering from many problems because of the lack of comprehensive developing strategy although considerable investments have been inputed by the public sector since 1970's. For 3 reclaimed sites in Chonnam Province chosen as case study areas, the analysis, the third attempt of widely-spanned studies on areal conditions, concentrated on their living conditions. Its results were as follows : 1. Although rural residents have increased their concern on health and medical services, the public sector can only serve basic and emergent level of them, and therefore, the private sector, which is mostly placed in urban areas and costed much higher than public one, has the dominant share of those services. So, because those costs are a great expense to rural residents, their supplying system should be planned with special reference to lightening the economic burden of them. 2. By the development of locally fitted programs and innovative systems, the rural education should be qualitatively improved to deal successfully with its small scale. That will result in increasing the schooling rate to schools in rural communities, lightening the economic burden of rural residents on education services and finally activating them to contribute the betterment of rural education. 3. Servicing level of water supply, sewerage and garbage disposal in the reclaimed areas has been remaining at the lower order even in other rural areas. In the design of rural water supply, average daily consumption per capita should be changed according to the composition rate of fishing households and variety of the source of water supply. 4. Most of rural residents in the reclaimed areas want to establish the welfare facilites for the infant, youth, aged and public bath However in the long-term basis, the cooperative production and processing facilities should be considered for modernized efficient farming.
