We should have a new perspective on the words, green and growth, to have a full understanding of them and consider the environment itself as leading to the nation's growth. The green growth policy is to convert the paradigm of economic growth into one with a good circle of environment and growth. However, as each country has a different view of the green growth policy, we will see how the countries carry out the policy and how the companies and people accept it. To do this, we will employ an actual analysis and propose a green growth strategy for the nation. The following are from the actual analysis in the article: 1. The GG policy is not just limited on the environmental problems but related to the nation's well-being as well. 2. Energy policy should be defined as the core thing of the GG policy and energy effectiveness among others things should be carried out on a short term basis. 3. Developing a strategy using IT is necessary for the GG policy. 4. Very careful approach should be taken to build a master plan for the nation bearing effective outcome of the policy. 5. The GG policy should be regarded as a social reformative one motivating the nation's much interest in it.

In this paper, a small supersonic wind tunnel was designed and built to studythe flow characteristics of a supersonic impulse turbine cascade by experiment. Theflow was visualized by means of a single pass Schlieren system. The supersoniccascade with 3-dimensional supersonic nozzle was tested over a wide range ofpressure ratio. Highly complicated flow patterns including shocks, nozzle-cascadeinteraction and shock boundary layer interactions were observed.

An important purpose of screening DSM(Demand Side Management) programs is to determine which programs or technologies seem to be moot worthy of further development, given the characteristics of the particular utility system. Complication found in screening DSM technologies is the consideration of costs and benefits from several perspectives : the utility, society, participants, free riders and nonparticipants. In this paper, a nation-wide DSM screening model is presented using a rigorous mathematical formulation on the financial basis and the concept of marginal coots considering all affected parties inside the nation is fully exploited.

인터넷이 활성화 됨에 따라 공간이나 시간적 제약이 감소하였다. 인식 부족과 사용자 환경에 의해 미진하였던 철도 물류 정보 시스템도 웹을 기반으로 서비스 체제를 변경함으로 인해 효율적이고 편리한 서비스를 제공할 수 있었다. 제안한 시스템은 기존 XML로 처리되는 데이터 뿐만 아니라 철도를 통해 운송되는 화물(컨테이너 등)에 대한 추적 정보를 제공하거나 화물 운송에 대한 실적 및 정산 정보를 알 수 있다. 또한 철도를 통해 운송된 화물에 대한 통계 자료나 화차에 대한 운송 현황 자료 등을 추출하여 물동량 파악이나 철송 업무에 활용할 수 있다.

The ion energy distributions (IEDs) arriving at a substrate strongly affect the etching rates in plasma etching processes. In order to determine the IEDs accurately, it is important to obtain the characteristics of radio frequency (rf) sheath at pulsed rf substrates. However, very few studies have been conducted to investigate pulsing effect on IEDs at multiple rf driven electrodes. Therefore, in this work, we extended previous one-dimensional dynamics model for pulsed-bias electrodes. We obtained the IEDs using the developed rf sheath model and observed that numerically solved IEDs are in a good agreement with the experimental results.

Health promotion programs are becoming a vital component of comprehensive health care services worldwide for individuals and population, and health promotion activities have been a major component in advancing overall health of population. Promoting the health of individuals is akin to promoting the health of the community as these are closely linked to each other. Likewise, the health of every community in every state determines the overall health status of the Nation.(omitted)

With the world becoming increasingly affluent in terms of material wealth, individuals' mental health appears to be lagging. "Dopamine Nation: Finding Balance in the Age of Indulgence" offers a new perspective on the meaning of addiction and its solutions in modern society with disparities. This book discusses addiction from the perspective of the balance between pain and pleasure. However, it also offers insights into the mindsets of modern humans, going far beyond the boundaries of addiction.

We demonstrate a high color gamut liquid crystal display (LCD) system (>100 %) by using a precompensated tri-chromatic LED-backlight module over a temperature range of (25 to $70^{\circ}C$), whose pre-compensated optical characteristic balances the spectral redshift and intensity decrease due to the temperature rising during operation.
