This study examines how economic preparation for later life directly influences life after retirement. As people's life cycle is gradually getting longer, preparation for the later time with less economic activity after retirement is becoming more important. Thus, this study analyzes the factors influencing life after retirement. Data comes from the Korean Retirement and Income Study (KReIS) surveyed carried out by the National Pension Research Institute in 2015. The analysis includes Cronbach's alpha, Pearson Product Moment Correlation Coefficient and Sobel Test. This study confirms that voluntary retirement has a positive influence on life satisfaction. Results are in line with previous research about the relationship between voluntary retirement and retired life. When a person retires voluntarily, financial preparation can be made in advance for retirement. In case of involuntary retirement, people may experience a sense of loss in personal standing and financial difficulties due to the unexpected situation. Especially, early retirement from the main workplace leads to unstable later life. The study's policy recommendation, in particular, calls on government and businesses to agree on social responsibility for helping employees to retire in the predictable retirement time and, thus, enabling the retiree to decide all aspects of the path after retirement.

The main purpose of the study is to determine the key aspects of the public-private partnership system in the context of the economic development of the state. At first glance, the mutually exclusive interests of the state and business do not contribute to the development of common and agreed development goals. At the same time, ignoring the versatility of interests and the aggravation of the discussion regarding the two sides under consideration, the study of the theoretical foundations of the interaction between the public and private sectors of the economy allows us to draw the following conclusion: world economic theory from classical political economy to new institutionalism has a clear structured position on the ancient historical depth of existence of the form of partnerships Based on the results of the study, the main elements of the public-private partnership system in the context of the economic development of the state were identified.

Purpose - On the basis of discussing the network economy concept and the commentary of the marginal revenue decreasing of traditional economic theory, The concept of network economy has just been put forward in recent years. The reason why such a concept appears is that the information technology, marked by computer network, plays an increasingly important role in economic activities. Some people define network economy as an economic form based on network technology and human capital. this paper points out network economy existing the marginal revenue increasing and analyzes the reasons that influencing the marginal revenue increasing. Research design, data, methodology - The network economy has fundamentally changed the traditional economic laws. The economic basis of industrial society is the law of incremental marginal cost, which reflects the socialization of high cost in industrial society. Results - As the number of network members increases, the value of the network increases explosively, and the value increases attract more members to join, resulting in more returns. Conclusion - In conclusion, network economy has changed many aspects of traditional economy, resulting in decreasing marginal cost, decreasing transaction cost in and out of enterprise organizations, and making the effect of increasing scale compensation more prominent. This is of great significance to the information construction in China.

본 논문은 국내 녹색건축물인증제도와 독일의 지속가능한 건축물 인증제도의 평가항목을 비교하여 국내인증제도의 발전방향을 제시하는 것을 목적으로 한다. 오늘날 세계적으로 많은 친환경건축물 인증제도가 시행되고 있으나 상호 비교 가능한 평가항목은 제시되지 않은 상황이다. 이에 국제표준규격에서는 지속가능한 건축물에 대한 평가기준을 마련하였고 독일의 지속가능한 건축물 인증제도는 이러한 평가기준을 받아들인 최초의 인증기준이다. 녹색건축물인증제도를 독일의 지속가능한 인증제도와 비교한 결과 녹색건축물인증제도의 평가내용에는 환경측면(62.6%) 이외의 사회문화와 기능측면(25.4%), 경제측면(3.0%)의 평가항목을 가지고 있는 것으로 나타났다. 이는 앞으로 녹색건축물인증제도의 사회측면 및 경제측면의 평가항목개발에 중요한 방향을 제시한다.

The purpose of this study was to investigate the economic effects of a flame retardant aluminum screen developed by a company Economic effects were analyzed in terms of micro and macro-economic aspects. In the macro-economic aspect, economic effects were analyzed under the assumptions that the total import volume of flame retardant aluminum screen was approximately $50m^2$ in 2015 and that possible import substitution rates were 100%, 80%, and 60%. Results showed economic values of 2.25 billion won (100% import substitution rates), 1.8 billion won (80% import substitution rates), and 1.35 billion won (60% import substitution rates). If existing farms which had been using imported flame retardant aluminum screen replaced it newly developed with the flame-retardant aluminum screen developed in this study at rates of 100%, 80%, and 60%, the farms could save 750 million won, 60 million won, and 45 million won, respectively. Furthermore, the social cost savings from fire prevention could be 1.184 billion won. In the micro-economic aspect, if a farm with a typical-size ($1,000m^2$) greenhouse growing red pepper wanted to install flame retardant aluminum screen instead of generic aluminum screen, the farm may only pay an additional cost of 720,000 won. In comparison, if the farm chose fire insurance instead of flame-retardant aluminum screen, then the farm would pay 21,000,000 won for fire insurance. The above results show that the economic effect of flame retardant aluminum screen developed by the company would be be very efficient compared to the imported one.

Loss and damage have become a vital contemporary issue in climate change studies and actions in developing countries. However, studies are scant on this in the fisheries sector around the world. In Bangladesh, there is no study on the loss and damage in fisheries dependent communities. This study assesses economic and non-economic loss and damage to coastal shrimp farms due to cyclone Bulbul in Gabura Union of Shyamnagar Upazila, Satkhira district, using a mixed method approach. Results show that all shrimp farms' dependent communities are affected by cyclone Bulbul to some extent. About 14%, 57%, and 29% of the farms were totally, heavily and moderately damaged due to farm inundation and dyke damage. The estimated mean loss and damage per shrimp farm was worth USD 4,633. Around 31% and 72% of the farms' fencing nets and traps were lost, which was worth USD 333 per farm. There were also loss and damage to other resources such as houses, solar panels, livestock and agricultural crops where the estimated mean loss and damage per household was worth USD 3,170. This study reported that the rich shrimp farmers encountered proportionately more economic loss and damage than their poor counterparts. However, this does not mean that the poor suffered less. The current study found a range of non-economic loss and damage in different aspects of the shrimp farmers' household members such as unbearable mental pain, deterioration of health, physical injuries, disabilities, etc. and access to services (e.g., inadequate food, lack of safe drinking water, lack of medical facilities, disruption of education systems), social infrastructure (e.g., damage of roads and markets) and disturbance of cultural functions. The findings suggest that urgent short- and long-term actions may be taken to save the aquaculture farms and dependent livelihoods from economic and non-economic loss and damage to cyclones in future.

이 연구는 1990년대 초반부터 시작된 북한의 경제특구 실험의 의의를 북한의 체제변화와 한반도 지정학적 질서의 변화 측면에서 살펴보았다. 구체적으로 북한 경제특구 정책의 변화과정을 북한 경제특구 전략 고유의 영역화 논리, 분권화/분산화에 대한 강조, 그리고 중국 개혁개방모델과의 비교 등 세 가지 측면을 중심으로 분석하였다. 이를 통해 북한 경제체제의 변화를 폐쇄에서 개방으로 이해하는 단선적 접근을 비판하고, 북한 특구전략의 역동성을 다층적인 차원에서 접근하였다. 북한의 경제특구전략을 경제난에 의한 불가피한 선택이나 중국과 같은 개혁개방 노선을 따르는 것으로 이해할 수는 없으며, 오히려 특구전략 기저에 작동하고 있는 지정학적 논리와 함께 지방경제발전에 대한 강조를 중심으로 보아야 한다고 주장하였다.

D&B(Drill & Blast) 공법은 터널 시공시 현장지반조건에 대한 신속한 대응능력이 장점으로서, 정보화 시공에 의한 피드백해석(feedback analysis)이 필수적이며 이때 터널변위에 대한 신속하고 정확한 계측이 요구된다. 본 연구에서는 터널내공변위 계측에 있어서의 기존계측 사례와 첨단 IT기법을 이용한 계측사례의 비교 분석을 통한 적용성을 분석하고자 하며 적용성 평가를 위해 00지하철 현장에서 내공침하 비교계측실험을 실시하였다. 또한, 계측비용, 계측빈도, 계측간격, 계측기간, 계측소요시간 등을 평가항목으로 선정하여 실제 현장터널의 내공 및 천단변위 계측시 소요되는 계측 용역의 내역자료를 통해 경제성을 분석하였다. 따라서 터널 시공시 기존방법에 비해 보다 안전하고 경제적인 시공에 기여함으로써 첨단 IT기법을 응용한 레이저스캐너의 현장 적용성이 높다고 판단된다.
