With the advent of the space age and the need to determine the requirements for a space cabin atmosphere, oxygen effects came into increased importance, even though these effects have been the subject of continuous research for many years. In fact, Priestly initiated oxygen research when in 1775 he published his results of isolating oxygen and described the effects of breathing it on himself and two mice, the only creatures to have had the “privilege” of breathing this “pure air”.Early studies had demonstrated the central nervous system effects at pressures above one atmosphere. Light microscopy revealed extensive damage to the lungs at one atmosphere. These changes which included perivascular and peribronchial edema, focal hemorrhage, rupture of the alveolar septa, and widespread edema, resulted in death of the animal in less than one week. The severity of the symptoms differed between species and was age dependent, with young animals being more resistant.

“A system of private ownership must provide for something more sophisticated than absolute ownership of the property by one person. A property owner needs to be able to do more than own it during his lifetime and pass it on to someone else on his death.”1 Those who own things with a long life quite naturally feel the urge to deal in segments of time. Most of the owner's ambitions in respect of time can be met by the law of contract. But contract does not offer a complete solution, since contracts create only personal rights. Certain of the owner's legitimate wishes can be achieved only if the law allows them to be given effect in rem—that is, as proprietary rights. Legal systems have responded differently to the need for proprietary rights limited in time. Roman law created usufruct and other iura in re aliena; English law created different legal estates. Every system has faced similar problems. One issue has been the extent to which the holder of a limited interest should be restricted in his or her use and enjoyment in order to protect the holders of other interests in the same thing. A common core of principles regulates the relationship between those who hold temporary interests and the reversioners. For instance, every system forbids holder of the possessory interest to damage the thing arbitrarily. But other rules are more controversial. This study focuses upon the rules which do not forbid, but compel, certain courses of action.

This essay discusses based on Qur’anic value and character education. In gobalization era, it has great impact on young behaviour change such as fighting, free sex, drug and other delinquencies. The occurred result is serious enough and it cannot be assumed just as a simple matter again, mainly that the subjects and the victim are young people whose have professions as students. The fact indicates that education world has to give an important role toward preventing national moral decadency in the effort of preparing the better future young generation. In this regard, we are aware that the education goal, basically, is to build better morality of human being or in another term is to “humanize the human being”. An idea regarding the significance of character education was appeared as a given solution in answering the morality problem in Indonesian education world. Character education is part of value education. That why, looking for the character education concept has been very urgent in the effort of preparing excellent, faithful, professional and personalized leaner as being asked by the education goal. The essence of characterized behavior actually is the psychological totality form which includes the whole human individual potency of cognitive, affective and psycho-motoric aspects, and also socio-cultural totality function in the context of interaction with God, him or herself, other human beings and the environment in his or her long life. Furthermore, in Qur’an’s teaching, the figure of the Messenger Peace be upon him (PBUH) is viewed as “the model human being”. In this context, the concept of Qur’anic charactereducation can be found through three moral dimensions that should be actualized in human being personality. They are the morality toward Allah (spiritual quotient/ intelligence), the morality toward our self (emotional quotient) and the morality toward Allah’s creatures, human being and environment (social quotient). Then, school should make the Holy Qur’an as the foundation of character education’s implementation whereas the implementation form in the school can be developed through intra-curricular, extra-curricular or personality and school culture development.
