최근 우리나라는 유례를 찾아볼 수 없을 정도로 고령화 진행속도가 빠른 나라로 공적 연금재정과 연금제도의 지속가능성에 대한 관심이 증가하고 있는 상황이다. 따라서 사회보장제도 개혁에 성공한 국가로 잘 알려진 스웨덴 사례를 통해 사학연금제도의 유지 및 장기적 재정안정화에 시사하는 바를 찾고자 한다. 스웨덴 정부는 인구고령화에 따른 위험에 상대적으로 안전한 '명목확정기여(Notional Defined Contribution)'방식을 도입하여, 개인의 연금계좌에 연금보험료를 적립하여 수급시점에 본인이 부담한 보험료 상당액을 연금으로 돌려받을 수 있도록 운영하고 있다. 또한 경제상황이 예상 수준보다 침체되고 연금 재정수지가 악화될 경우 이와 연계하여 자동으로 연금가입자의 부담금을 높이고, 지출되는 급여액을 감소시키는 '자동재정균형장치(Automatic Balancing System)'를 도입하였다. 상기와 같이 기여와 급여를 명확하게 연계시키는 스웨덴의 명목확정기여 방식의 연금제도는 장기적 재정안정은 물론이고 안정적인 연금 급여를 제공한다고 평가되고 있다. 스웨덴은 연금개혁 후 확정기여(DC)제도로 전환하여 장기적인 제도 안정성을 추구하지만 사학연금은 확정급여(DB)제도를 유지하면서 급여수준의 하향조정과 보험료율을 점진적으로 상향시켜 재정안정성을 확보하는 것이 가장 큰 차이점이다. 스웨덴의 연금제도와 같이 공적연금의 틀을 유지하면서 사적연금의 장점을 최대로 수용한 명목확정기여 방식의 연금제도를 도입한다면 급격한 재정부담 없이 장기적으로 지속가능한 연금재정 안정화에 기여할 수 있을 것이다. 일견 스웨덴의 정치, 경제상황 및 문화적 특성 차이로 인해 스웨덴의 연금제도 방식을 획일적으로 사학연금제도에 적용하는 것은 불가능하다. 경제상황을 고려한 기여와 급여의 연계 강화를 개혁의 기본방향으로 설정한 스웨덴의 사례를 벤치마킹하여 사학연금 또한 거시경제상황과 조화를 이루는 제도개선 및 자동안정장치를 마련해 보는 것도 고려해 봄직 하다. 지속적으로 스웨덴 및 연금제도 선진 국가들의 연금개혁안을 재검토하여 사학연금제도에 현실적으로 적용할 수 있는 방안과 시사점들을 찾는 노력이 필요할 것이다.

The purpose of this paper was to comparatively investigate the efficient building incentives in Korea and foreign countries and to seek strategies to enhance low energy building integrated design market infrastructure in Korea. The structure of incentive policies were composed of four main component: 1) types of financial aids and beneficiaries, 2) energy performance criteria and verification methods, 3) supports for low energy building integrated design, and 4) funding sources for incentive programs. Every overseas incentive program has adopted a design team incentive along with building owners incentive and the range of target buildings have been extended from new construction to remodeling projects. The main system of the program is the performance standard through which projects were investigated and the level of incentive are decided. Initially, the integrated performance has been investigated through simulation methods, but the construction performance evaluation and energy monitoring methods are emerging. In addition, the direct support and educational support for integrated design has been provided to enhance the foundation of relative markets. Financial funding is also a key component of the program and more aggressive funding strategies have been adopted.

This study started from the awareness of the issue if the citation index newly introduced to evaluate the quality of papers satisfies the proper timing matter, which is a component of performance indicators for the evaluation of government-funded R&D institutes. Accordingly, the study will propose improvement ways to shift the previous evaluation system to quality evaluation for mission-oriented R&D institutes by analysing and using the periodical characteristics such as citation half-life and immediacy index of papers. As a result, it turned out that the speed of academic change is getting faster in proportion to the dependency on the technological development but that the citation speed in the field of public technology is relatively slower and the speed of knowledge transfer in the fields related to industry is faster. In addition, the citation index among the R&D fields showed no differences, and the minimum period for citation index measurement with validity should be over 6 years. The problems of evaluation for mission-oriented R&D institutes were deducted based on the technical and statistical analysis results of the temporal characteristic of citation necessary for quality evaluation of performance among R&D fields. To solve the problems, policy alternatives for object and valid quality evaluation were proposed from the points of evaluation period, evaluation criteria, and evaluation management.

This study discusses mass unemployment and job insecurity due to the 4th industrial revolution and technological progress. In particular, the construction automation service method can contribute to increasing work productivity, preventing on-site safety accidents, and enhancing the competitiveness of the construction industry according to rapid development and convergence between technologies. However, there is great concern that the position of workers will decrease and the income distribution will deteriorate. Therefore, this study is necessary to alleviate the anxiety of the labor market and to find a direction for the government and all walks of life to ponder. To carry out this study, in-depth interviews were conducted with two experts currently engaged in the construction field, and through analysis, we intend to derive meaning and identify current trends, identify necessary improvement measures and institutional areas and suggest research directions. As a result of the analysis, it is possible to suggest a response strategy in a total of three themes: purpose, implication, and strategy. Based on this, there are response strategies in four areas: (1) industrial site response, (2) worker response, (3) education, and (4) training response, and government and corporate response. Through this study, it is necessary to revitalize economic and sociological discussions in the future so that the improvement in productivity and efficiency of society as a whole due to technological innovation of construction automation services does not lead to social problems such as an increase in the unemployment rate and a decrease in jobs in the labor market.

Analyzing the shortcomings and shortcomings of the film based on the Webtoon and the artistry as a popular artwork at the time when the filming of the webtoon is becoming the main trend of the Korean film, it is an analysis of the present state of the Korean film industry, Will be an indicator for. The present generation of young people who do not have the experience and knowledge of popular arts and culture that handed down a small number of high-quality arts by reflecting current literary, art, history, and popular consciousness are concentrating only on instinctive emotion, It is regrettable that it is consistently followed by follow-up and follow-up unconditionally. In this study, we will examine the methodology of the ideal webtoon filmization process by analyzing the structure and industry analysis of Webtoons, and analyzing the weaknesses in the transition process to the movie format. The essence of communicating with audiences will be unchanged even in the rapid change of media and technology. In the setting and expression of its essence, it is based on the humanistic authenticity mentioned above, the avant garde internal necessity of the artist seeking ideal, And the reflection of the original character of high-class culture that creates newness can be considered as a proposition that can include artistry in popular culture.

램제트 엔진은 비추력이 높고 추력 레벨은 낮으므로, 2단 추진기관에 적합한 추진 시스템이다. 1단-추진기관의 작동이 끝나고, 2단 램제트 엔진이 점화 후 안정된 연소에 도달되기까지 비행체의 속도는 항력에 의하여, 초당 약 마하수 0.1 정도씩 감소된다. 1단 연소 후 2단 램제트로 전환되는 지연시간이 길수록 1단에서 요구되는 종말 가속도는 증가되므로, 1단이 차지하게되는 부피는 증가되고 비행체의 크기 또한 늘어나게 된다. 따라서 1단에서 2단 램제트로 천이되는데 소요되는 시간을 가능한 짧게 하는 것이 효과적이다. 그러나 램제트 엔진의 특성상 선결되어야할 다음과 같은 여러 문제들이 있다. 첫째, 1단 작동 시 공기 흡입구와 연소실은 차단벽으로 분리되어 있다가, 1단 연소후 차단막이 제거되어 외부공기가 램제트 연소실로 흡입된다. 흡입되는 공기는 흡입구의 형상에 의하여 램 압축되지만 초음속으로 연소실을 통과하게된다. 연료 주입 구에서 공급되는 연료는 연소실에서 유동의 흐름방향(streamline)에 따라서 연소실로 확산되는데, 연소되기 전에는 유속이 빠르게 노즐로 빠져 나가므로 램제트 연료가 재순환 구역(recirculation zone)으로 침투하는데 쉽지가 않다. 둘째, 연소실 입구에서 발생되는 와류 (ring vortex)는 1단 연료의 고온 연소 가스를 연소실로 확산시키는데, 비 균일한 온도 분포를 유발하여 램제트 연료의 점화에너지가 공급되는 시간이 적당하지 않을 경우 균일한 화염 전파에 악영향을 준다. 셋째, 연소실에서의 빠른 유동 조건은 연료가 연소실에 머무를 수 있는 시간을 감소시키며, 연소실 입구에서 강한 전단 응력이 발생되어 화염이 안정화되는데 악 영향을 미치게된다. 본 논문은 공기 흡입구, 연소실 및 노즐을 통합하여 수치해석을 하였으며 열유동/점화/연소등의 미케니즘을 이해하고, 주요 인자들 중 와류의 영향에 초점을 맞추었다.다고 판단되며 배기 가스 자체에 대기 공기중에 함유되어 있던 습기가 얼어붙는(Icing화) 문제가 발생하기 때문에 배기가스의 Icing을 방지하기 위하여 압축기 끝단에서 공기를 추출하여 배기부분에 송출할 필요성이 있는 것으로 판단되었다. 출구가스의 기체 유동속도가 매우 빠르므로 (100-l10m.sec) 이를 완화하기 위한 디퓨저의 설계가 요구된다고 판단된다. 또 연소기 후방에 물을 주입하는 경우 열교환기 및 기타 부분품에 발생할 수 있는 부식 및 열교환 효율 저하도 간과할 수 없는 문제로 파악되었다. 이러한 기술적 문제가 적절히 해결되는 경우 비활성 가스 제너레이터는 민수용으로는 대형 빌딩, 산림, 유조선 등의 화재에 매우 적절히 사용되어 질 수 있을 뿐 아니라 군사적으로도 군사작전 중 및 공군 기지의 화재 그리고 지하벙커에 설치되어 있는 고급 첨단 군사 장비 등의 화재 뿐 아니라 대간첩작전 등에 효과적으로 활용될 수 있을 것으로 판단된다.가 작으며, 본 연소관에 충전된 RDX/AP계 추진제의 경우 추진제의 습기투과에 의한 추진제 물성 변화는 미미한 것으로 나타났다.의 향상으로, 음성개선에 효과적이라고 사료되었으며, 이 방법이 편측 성대마비 환자의 효과적인 음성개선의 치료방법의 하나로 응용될 수 있으리라 생각된다..7%), 혈액투석, 식도부분절제술 및 위루술·위회장문합술을 시행한 경우가 각 1례(2.9%)씩이었다. 13) 심각한 합병증은 9례(26.5%)에서 보였는데 그중 식도협착증이 6례(17.6%), 급성신부전증 1례(2.9%), 종격동기흉과 폐염이 병발한 경우와 폐염이 각 1례(2.9%)였다. 14) 식도경 시행회수는 1회가 17례(54.8%), 2회가 9례(29.0%), 3회 이상이 5례(16.1%)였다.EX>$IC_{50}$/ 값이 210 $\mu\textrm{g}$/$m\ell$로서 효과적

Sustainable development is important because the ultimate objective is efficient development combining the economic, social, and environmental aspects of urban conservation. Despite Korea's rapid urbanization and economic development, the distribution of resources is inefficient, and land-use is not an exception. Land use distribution is difficult, as it requires considering a variety of purposes, whose solutions lie in a multipurpose optimization process. In this study, Yangpyeong-eup, Yangpyeong, Gyeonggi-do, is selected, as the site has ecological balance, is well-preserved, and has the potential to support population increases. Further, we have used the genetic algorithm method, as it helps to evolve solutions for complex spatial problems such as planning and distribution of land use. This study applies change to the way of mutation. With four goals and restrictions of area, spatial objectives, minimizing land use conversion, ecological conservation, maximizing economic profit, restricting area to a specific land use, and setting a fixed area, we developed an optimal planning map. No urban areas at the site needed preservation and the high urban area growth rate coincided with the optimization of purpose and maximization of economic profit. When the minimum point of the fitness score is the convergence point, we found optimization occurred approximately at 1500 generations. The results of this study can support planning at Yangpyeong-eup.ausative relationship between the perception of improving odor regulation and odor acceptance.

This study aims to investigate the changes in the occupational structure of employment in Korea during the last three decades, in which have transformed from industrialized economy to knowledge-based economy very rapidly as well as having experiences of both IMF and financial crisis. For this purpose, we analyze the trends occupational distribution and the socio-demographic characteristics of the occupational structure of employment since 1980. By applying correspondence analysis of Multidimensional Scaling(MDS) methods, we examine the inter-relationships between the employed persons by occupation and their characteristics such as gender, age group, educational attainment, industry, region. We found the occupational structure of Korea has been changed dramatically with the socio-economic transformations during the last four decades. In particular, the occupational (job) structure has been highered in general. However, it has also been dualized extremely into two groups, one is the specialized-skilled-white color jobs and the other is the simple-unskilled-blue color jobs. The results of this study could be utilized as the importation basis for the provision of labour supply and employment policy plan at the national level as well as at the local level.

The purpose of this article is to examine whether Myanmar's experience in which dealing with the most exemplary change among rogue states or pariah state in the 21st century is feasible for North Korea's case. Recently, North Korea's willingness to dialogue, reform and open is similar to the precedent in which the Myanmar military junta dismantled its ruling system and turned over transition period through general elections in 2010 and 2015 each. The so-called 'Myanmar Model' refers to a country branded as a rogue state which has been under the international sanctions and pressure, and opening its political system and the market by choosing transformation. However, rapid changes in speed across the entire society after opening up are impossible because the political elite is only the leading role and implementation in the transition. In case of Myanmar, military culture has penetrated into society due to such a long-lasting military dictatorship, and even democratic bloc has become accustomed to authoritarian decision-making process. Furthermore, the "reserved area" of the old regime still exists in a deformed political structure that can not retrieve the interests of the military. Therefore there could not be achieved political development in term of qualification. North Korea also appears unlikely to achieve political and economic assessment in a short period of time, as civil society has not appeared due to its long dictatorship and very low economic development levels. Like Myanmar, North Korea is also likely to control the pace and direction of upcoming reforms and open, as the dictator or most powerful person chose to reform and open up. Therefore, if North Korea moves toward the 'Myanmar Model', there will be high expectations of new changes in the short term, but it could be delayed or stalled in the mid and long term.

Nowadays, the employment policies for older people is requested to become the new form in the change of information, globalization, and aging. It is discussed, simultaneously, about an age integrated society as the full time jobs' continuation and social jobs after the full time jobs. The discussion of jobs' continuation include from institutional system to age integrated society. Social jobs include from public labor to social wages. jobs' continuation passes over stabilization, regarding it as ideal society. social jobs are interpreted it as residual welfare, excluding the meaning of social solidarity. In fact, most of the debates is overwhelmed by the logic of economy. And so they pass over the quality of life of individuals. Therefore, this study critics the employment policies for older people in the present situation and states a direction improving the quality of life older people.
