  • In early 90s the worldwide awareness about the energy crisis and global warming had been increased and emission reduction (by improving energy efficiency), as well as increasing the capacity of clean and renewable energies, showed themselves as the most important steps towards the sustainable development approach. However, investigations on Iran's environmental situation show huge decline in recent decades and apparently there is no sense of urgency about these issues through the vision of Iranian politicians. In this article the idea of replacing the old gas turbines of Polkalleh natural gas compressor station - as one of the main compressor stations of Iran - with newer and more efficient gas turbines is evaluated, emphatically for reducing greenhouse gases emissions and their environmental costs and decreasing natural gas consumption as well. Clearly such idea is costly, but analyzing its economic impacts, huge declines in annual costs and greenhouse gases emissions can be seen as well. So an investment about $95 million can decrease 40% of Polkalleh compressor station annual costs, 25% of natural consumption and 30% of $CO_2$ and $NO_x$ emissions. Besides the simple payback period of this investment is about 2.5 years from the cut-expenses of annual costs.

  • 본 연구는 생태 위기 앞에서 요구되고 있는 생태학적 기독교 영성을 통항 기독교교육의 방향과 실천을 제언하는 글이다. 환경파괴와 생태계의 문제는 인류의 생존까지 위협할 수 있는 심각한 위기로 인식되고 있다. 그로 인하여 지금까지 인류가 당연히 여기고 있던 물질문명의 발전에 의문을 던지게 되었고 생태 위기의 근원에 자리하고 있는 인간의 의식과 사고의 변화가 불가피하게 되었다. 문명의 위기는 새로운 영성을 요구하며 생태 위기 앞에서 요구되는 영성은 생명 친화적인 영성이어야 한다. 1970년대 이후 등장한 생태 위기에 대한 담론들은 생태 위기에 대한 근본적인 시각을 제공해준다. '내재성', '상호 관련성', '치유와 해방', '지속성'이라는 생태 영성의 개념들은 위의 다양한 담론들의 논의들을 이해하고 집약할 수 있는 개념들이다. 이를 기초로 하여 본 논문은 하나님과 인간, 몸의 영역으로 나누어 기독교적 생태 영성을 살펴보았다. 이를 통하여 만물 위에 군림하시는 초월적인 하나님이 아니라 만물이 출현하도록 자신을 비우시고 만물의 고통을 함께 나누시며 만물을 유지하시고 그 안에 거하시는 하나님 이해를 통하여 소박한 삶을 위한 자기 비움의 실천적 자리로서 기독교교육을 제안하였다. 거기에서 묵상과 환대는 소박한 삶을 위하여 내면을 풍성하게 할 수 있는 실천적 기독교교육의 자리가 될 수 있다. 몸을 경시하는 이분법적 사고와 내세지향적인 시각에서 몸의 영성을 강조하는 생태학적 기독교 영성을 통하여 통전적인 앎의 자리로서 기독교교육을 제안하였다. 거기에서 성만찬은 몸의 영성을 회복하는 통전적인 교육과 생태학적 교육이 동시에 이루어질 수 있는 자리로서 중요한 의미를 갖는다. 이를 통하여 기독교교육은 이성만이 아니라 통전적으로 그리스도를 알아나가며 생태계와 이웃과 '더불어' 살아가는 법을 배우는 교육의 장이 되기를 기대해 본다.

  • 본 연구는 현대사회가 과거에 비해 매우 심각한 '생명 위기'의 시대를 맞이한 것으로 보는 한편, 이러한 생명의 위기가 일반 교육은 물론 기독교교육에 있어서도 매우 시급하고 중요한 과제라는 점을 전제한다. 그 이유는 기독교가 생명을 소중하게 여기는 생명의 종교이며 이 생명의 위기에 대처해야 할 막중한 사명을 생명의 하나님께로부터 받았기 때문이다. 이에 본 연구는 기독교의 안식이 오늘날 생명의 위기와 밀접하게 관련된다는 전제하에 기독교교육이 생명 위기의 시대 가운데 실천해야 할 과제를 모색하는 것을 그 목적으로 삼는다. 보다 구체적으로 먼저 연구자는 현대사회를 성찰하여 오늘날 발생하는 주요 생명 위기의 현상에는 고의적 자해에 의한 죽음, 산업재해로 인한 사망 사고, 취약계층의 현실과 이에 대한 무관심 및 무감각, 그리고 자연환경의 파괴가 있다고 진단한다. 또한 이러한 생명 위기의 현상에 있어서 신자유주의, 성과주의, 소비지상주의와 물질만능주의, 이기주의와 인간중심주의가 그 원인으로 작용하고 있다고 비판한다. 그런 후에, 기독교의 안식에 대한 성서적 및 신학적 고찰을 바탕으로 생명의 위기와 긴밀하게 연관되는, 현대사회에서 기독교의 안식이 가진 목적과 의미를 삶과 생명의 주도권이 하나님께 있다는 사실의 인정, 생명력을 공급하시는 하나님과의 만남, 거룩한 삶으로서의 안식의 실천, '생명 사역'으로서의 안식에의 참여라고 해석한다. 끝으로 이러한 기독교의 안식이 가지는 목적과 의미를 바탕으로 기독교교육이 생명의 위기에 대처하기 위해서 적극적으로 실천해야 할 과제로 하나님께서 생명의 주관자가 되심을 일깨우는 교육, '생명문해력'을 함양하는 교육, 생명 위기에 저항하는 교육, 그리고 생명의 안녕과 평화를 추구하는 교육을 제안한다.

  • This paper attempts to prove the possibility that Women in Love can be approached by ecological thought. It is necessary to research the family of Lawrence's childhood, the environmental surroundings and Lawrence's viewpoint of nature to prove the possibility. The most urgent problem for us in the modern world is the ecological crisis due to the destructive aspect of modern civilization. This Lawrence's attitude toward the modern civilization is clearly reflected in Women in Love. Lawrence diagnoses the destructive aspects of modern civilization and the human relationship through Gerald, Gudrun, Hermione and Loerke who represent the industrial society and suggests the apocalyptic vision to the human being from the nature. Lawrence thinks that we must restore the animated power of life to revive the modern man who lost the vital power of life. Birkin and Ursula represent this thought of Lawrence and they accomplish the idealistic human relationship based upon the true love and the real life. They do not have the posture of the binomial contrast that separates the human being from the nature, This posture of the binominal brings to one of the causes of the present ecological crisis. As a result, we can say that Women in Love is the novel that belongs to the category of literary ecology. And we can regard that Lawrence previously presented the paradigm that ecologist advocates.

  • Recently Korea has stepped into a stage of sluggish development, and the unemployment of young people has become a major issue. Especially in 1998 IMF economic shock was influential in formulating government policy and social economic structure on employment. Restructuring now becomes everyday words and further restructuring is already under way. Owing to the growing economic crisis and resultant unemployment and initial appointment shall be considered conditional. Young job seekers are grappling with mastering their native language and unnecessary experiences. These unnecessary experiences are needless waste of time and money. Educational system in university may be affected by environmental changes in population of students and business crisis. Sometimes the departments made a very low rate of employment may be abolished or merged in university. The government will demand us in the work of reform by doing NCS. The government is now ask to teach, train and employ students on the basis of NCS especially in high-school, job training center, and college and university. NCS has advantages and disadvantages. NCS may reduce waste of time and money to make unnecessary experiences, provide standard course to prepare educational system. It will be a big help to adapt properly and make better employment system. The most negative element of the program is application to humanities and social sciences by the same standard with technology and engineering department in the university. Standardization of each educational course will not react quickly to rapidly changing situations in the future.

  • Both internally and externally environmental changes surround the rural areas such as rapid growth of the early-retired employee under the WTO, the Asian financial crisis in 1997, and the financial crisis in 2007 brought about much transformation in our rural residential environment. According to this changes and demands, the rural areas have been transformed from the area for farmer to the area for farmer and non farmer, that is, peoples that to leave the city to go back to farm or return to home village. Of this time, there needs a change in rural development policies which can make the urban residents migrate and settle in the rural areas as they are naturally embracing the rural life according to the social background and demand. In this point of view, we attempted, in this paper, to survey and analyze the changing trends of residential environment following the spatial composition with house types and rural villages in rural areas. The result of this study will be expected to be a reference for the direction of desirable residential environment in rural areas.

  • Human has faced in lack of fossil fuel and environmental crisis because of high population growth and development of industry. Hydrogen, unlimited amount and clean resource from water electrolysis, is remarkably known as the solution of recent energy crisis. One of the special characteristics of hydrogen is that a little amount of catalytic such as platinum and palladium makes nonflammable combustion, in other words catalyst combustion. Catalytic combustion fueled by hydrogen is environmentally friendly. This paper considers some comparisons of characteristic of catalytic combustion between a single layer of platinum catalyst, double layer of platinum and nickel catalysts and mixture of platinum and nickel catalysts. Some experiments of temperature distribution at different positions and characteristic of combustion in low temperature region were done in order to find an applicable possibility as a house-cooking burner.

  • An energy crisis is expected in near future. Fossil fuel such as oil and natural gas has been used and will be no longer supplied enough to demand in the beginning of coming century. The use of the fuel makes a lot of environmental pollution to threaten human being's health especially in big cities and produces a lot of $CO_2$ to make green house effect of the earth. It is the time to use clean fuel such as hydrogen to prevent the expected energy crisis and the pollution. A new engine such as fuel cell can be used instead of the conventional internal combustion engine with 2 to 3 times higher efficiency of the conventional engine. The fuel cell uses hydrogen and oxygen and produces electric energy and pure water, which is a calm engine without air pollution. In big cities the city buses and the taxies powered by hydrogen fuel cells are suggested to be operated for clean environment. A model of the total energy system for production, transportation and utilization of hydrogen is calculated.

  • Purpose - Not all firms are able to completely eliminate the risk arising out of the crisis. Success hides in the ability to perceive the market expectations accurately and take correct decisions. This study aims to analyze the firms' decisions at gross-root level. Research Design, Data, and Methodology - Primary data is obtained with the help of specially designed questionnaires from the agriproducts export firms that are members of export union of Turkey. The study is based on four theoretical structures: general planned behavior theory model, perception-leading behavior control and subjective norm model, perceived-behavioral-control leading perception and subjective norm models, and perceptions and subjective norms leading behavior control model. Structural Equation Models (SEM) is used to conduct the empirical analysis. Results - The findings show perceptions and subjective norms leading behavior control model as the best one, concluding that the environmental pressures and positive perceptions have significant effect on the strategic decisions of the agriproducts export firms. Conclusion - Policy tools like creating positive perception in the markets, providing sufficient information and financial support to the firms and increasing market competition can be used effectively to achieve the said objective.

  • During the past two decades, the Southeast Asian region has experienced a range of major crises. Service industries such as tourism and the marginal and migrant laborers who work in them have usually been at the sharp end of these testing events, from natural and environmental disasters, epidemics and pandemics, global financial slumps, terrorism, and political conflict. The latest challenge is the "Novel Coronavirus" (Covid-19/SARS-CoV-2) pandemic. It has already had serious consequences for Southeast Asia and its tourism development and these will continue for the foreseeable future. Since the SARS epidemic of 2002-2004, Southeast Asian economies have become integrated increasingly into those of East Asia (China, Japan, South Korea, Taiwan, Hong Kong). This paper examines one of the most significant current crises, Covid-19, and its consequences for Southeast Asia, its tourism industry, and its workers, comparing experiences across the region, and the issues raised by the over-dependence of some countries on East Asia. In research on crises, the main focus has been on dramatic, unpredictable natural disasters, and human-generated global economic downturns. Not so much attention has been devoted to disease and contagion, which has both natural and socio-cultural dimensions in origins and effects, and which, in the case of Covid-19, evoke a pre-crisis period of normality, a liminal transition or "meantime" and a post-crisis "new normality." The transition is not straightforward; in many countries, it operates as a set of serial lockdowns and restrictions, and to predict an uncertain future remains difficult.
