Environmental Control & Life Support System (ECLSS) technology is essential for humans to live safely in space other than on Earth and celestial bodies (ex, Moon, Mars etc.) in our solar system. Life support systems generally consist of Air Management System (AMS), Water Recovery System (WRS), and Waste Management System (WMS), and it can enable humans to breathe and live in enclosed dwellings in outer space. First, this paper described the development trends of life support systems that have been developed under the leadership of NASA. In addition, we introduced the current development status of life support system in operation on the International Space Station (ISS) and prospected the development trends in Korea.

This is about studying on the environmental ethics of Taoism mainly based on Taoism's Bioautonomous. Taoism is the most comprehensive thought in the traditional thoughts of East Asia. According to Taoism, every individual bio has its own intrinsic value having nothing to do with the value estimated by human beings since it has Daoxing. Human beings, however, have their own bioautonomous which is different from other individual bio. In Taoism human beings are independent for their lives. They do not depend on nature, but they can control themselves. That is to say, their lives depend not on god but on their own wills. The human beings' bioautonomous includes two different meanings: one is that human beings can use other individual bio as a tool for their eternal youth, and the other is that human beings are the main character of realizing the intrinsic value of universal bio and bringing harmony into each individual bio. In Taoism the harmony of universal bio is considered as the top value. Realizing the value of human beings is based on keeping harmonious order of universal bio and realizing the value of other individual bio. the environmental ethics of Taoism is not Biocentrism. Biocentrism argues that each individual bio has teleological center of life, which pursues its own good in its own way, and possesses equal members of Earth's community. As a result, human beings role and responsibility was reduced. But Taoism insists on human beings' bioautonomous. And human beings should be responsible for universal bio's harmony. Therefore the environmental ethics of Taoism is not Biocentrism but Bioautonomous. Bioautonomous environmental ethics of Taoism insists on human beings should be responsible being in relation with other living beings. Because of this point, it can be a theory of biorecovery.

The purpose of this paper is to create an inter-religious dialogue between the Western Christian concept of the spirit and Eastern ch'i philosophy within the category of panentheism. The Hebrew term ruah means 'moving air' and 'wind' which derive from the particular experience of the ancient Hebrew people living in the desert. The Greek pnuema also means 'life' and 'wind' which denote the natural power. Both ruah and pneuma consist of the main idea of the spirit exploring the symbol of relationality of the divine in Western tradition. Eastern ch'i philosophy indicates a vital force for keeping the body and soul alive, which is unconscious and spontaneous. Ch'i as a vital force constitutes cosmogony and cosmology with the constant movement of yin and yang. Yin and Yang as representing earth and heaven are dynamic breaths, blending harmoniously to become all existence. The ethical implication of the inter-religious dialogue between the spirit and ch'i would be the integration and interconnection of heaven, earth, and human beings. The dialogue suggests becoming one body with nature and human community through embodying the non-dualistic spirit of life. The inter-relationality means that since all modalities of existence are made of the cosmic life, human beings are part of the divine cosmic process. This is related to degree of spirituality in the entire chain of being: rocks, trees, animals, humans, and goods represent different levels of spirituality based on the varying composition of the spirit and ch'i. All beings that internally embody with the spirit and ch'i are organically inter-connected, and they are integral part of a continuous process of transformation of life towards holistic liberation of human and nature community.

It is essential to study the effects of hypergravity on the human body in the research field of aerospace medicine. Previous studies have shown that hypergravity could act in a harmful way to the human body. However, recent studies have shown that moderate degree of hypergravity can act in a beneficial way to the human body. The authors have in particular been studying the effects of hypergravity on immune diseases, especially allergic asthma and rhinitis. Therefore, this review paper will introduce the results of recent studies on hormetic (health promotion) effect of hypergravity. In addition, this review paper also examines the mechanism by which hormetic effect of hypergravity could be possible. Furthermore, we will also discuss how to apply these hormetic effects in clinical practice.

Obstructive sleep apnea syndrome (OSAS) can lead to severe complications if left untreated, and therefore should be adequately diagnosed and treated, especially in airline workers. The aviation medical examiner (AME) should induce the patient to cooperate for the diagnosis and treatment of OSAS, by notifying the subject that it does not cause disqualification of the air service and that it is a disease that can be sufficiently controlled and treated by various treatment options. AME should also warn about medical complications and the possibility of serious air accident risks when untreated, and encourage the subject to receive appropriate diagnosis and steady treatment such as continuous positive airway pressure and/or surgical treatment.

인간이 생존하기 위하여 필요한 것들 중에는 음식, 물, 산소 그리고 피신처를 들 수 있을 것이다. 미 우주항공국(The National Aeronautics and Space Administration (NASA))에서는 21세기에 인간을 화성에 보내고, 달과 화성에는 기지를 세워 사람이 살수 있도록 하고자한다. 화성까지의 왕복 소요 시간은 3년여 이상으로 이 기간동안 우주선 승무원들이 소비할 산소, 물 그리고 식량의 양은 방대한 양이며, 우주공간으로 쏘아 올리는데 많은 에너지가 필요하기 때문에, 경제적으로 재생산이 가능한 생명지원시스템을 고려하고 있다.

There are various systems that allow humans to safely maintain their space exploration missions and lives in completely different environments, such as the International Space Station, the Moon (the closest celestial body to Earth), and Mars (the only planet in the solar system for manned mission in the 2030s). Among them, when it comes to maintaining the basic breathing of humans, the human life support air management system is a key device system. Such an air management system can be used not only for space exploration but also for undersea bases and submarines on Earth where humans reside. The air management system basically consists of an oxygen generation system, a carbon dioxide removal system, and a harmful substance removal system. In this paper, in order to develop an air management system that can be used in an underwater residential platform, the development requirements of a ground test module to be used as an experimental facility were analyzed.
