Americans continue to have beliefs in the paranormal, for example in UFOs, ghosts, haunted houses, and clairvoyance. Yet, to date there has not been a systematic gathering of data on popular beliefs about the paranormal, and the question of whether or not there is a convincing trend in beliefs about the paranormal remains to be explored. Public opinion polling on paranormal beliefs shows that these beliefs have remained stable over time, and in some cases have in fact increased. Beliefs in ghosts (25% in 1990 to 32% in 2005) and haunted houses (29% in 1990, 37% in 2001) have all increased while beliefs in clairvoyance (26% in 1990 and 2005) and astrology as scientific (31% in 2006, 32% in 2014) have remained stable. Belief in UFOs (50%) is highest among all paranormal beliefs. Our findings show that people continue to hold beliefs about the paranormal despite their lack of grounding in science or religion.

Food and nutritional survey was made on two kinds of milk (one: 30 samples of bottled milk, the others: 30 samples of prepared milk), which are bottled market cow milk in Seoul city to examine the general ingredients, adulteration and degeneration. The results of survey indicated that the bottled milk delivered to home is relatively better than the prepared milk from the view point of food and nutrition. Moreover the quality of the prepared milk is poor because of adulteration through adding water or skim milk powder in order to increase quantity, consequently the prepared milk is under the nutritional standard. However it indicated that some of the bottled milk are rather inferior from the view point of food and nutrition, so certain measure is required for improving the quality of bottled and prepared milk. Most of the bottled milk and the prepared milk containing Coli-form bacteria have a possiblity to harm the citizen's health as a medium of infectious disease, such a fact is really serious problem from the view point of the national health, considering the general trend of milk consumption increase. It is urgent for us to take a scientific inspection on the sanitary management and take a formidable measure in handling of milk.

There is a great deal of current interest in the development of rechargeable batteries with high energy storage capability due to an increasing demand for electric vehicles (EVs) with driving ranges comparable to those of gasoline-powered vehicles. Among various types of batteries under development, a Li-O₂ battery delivers the highest theoretical energy density; thus, it is considered a promising energy storage technology for EV applications. Despite the fact that extensive research efforts have been made in the field of Li-O₂ batteries in recent years, there are still many technical challenges to be addressed, such as low round-trip efficiency, poor reversibility, and poor power capability. In this article, we provide a short review on the fundamental electrochemistry of Li-O₂ batteries with non-aqueous electrolytes and on electrode materials that have been employed in cathodes (oxygen electrodes). The major aim of this mini-review is to highlight the physical and electrochemical origins of scientific challenges facing Li-O₂ battery technology and to overview the strategies proposed to overcome them.

Despite the fact that the sourcing process in B2B e-Marketplaces is one of the most important tasks, the evaluation and selection process of suppliers have been ad-hoc based and mainly dependent on the experience of sourcing managers' subjective knowledge. To remedy the problem, we developed a decision support System (called Wise - I) that helps sourcing managers evaluate suppliers in a more systematic way. The system reflects company's strategy and know-how by adopting company enforced weighted scores for different factors and employing a more scientific method of considering factors other than price and on-time delivery rate, utilizing the AHP method. This paper reports the effectiveness of the system as well as the detailed description of the system. To investigate the effectiveness of the system, we collected information through interview and questionnaire survey. The information was also augmented through the firm key index system, which monitors average delivery lead time and on-time delivery rate. The result indicates that the system leads to the efficiency of purchasing section and the transparency of buying process, therefore reduces delivery time and cost.

This paper is primarily intended to propose a new concept of "aggregate control of road density" which is defined as the area-wide road surface per watershed area. An empirical study for experimental sites was conducted to confirm how a standard GIS technology can be used to assist in estimating the road density in terms of total volume threshold control. Guidelines for a replicable methodology are presented to provide a strong theoretical basis for the standardization of factors involved in the estimation of the road space threshold; the meaningful classification of road types, delination of watershed boundary, interpretation for distribution trends of road density etc. A variety of visual maps using overlay analysis can be generated over large areas quickly and easily to show the fact that some degree of road space already exists in the experimental sites. They could be used as an evidence to limit further construction of road network in comparison with other tributary watershed. It is anticipated that this research output could be used as a valuable reference to confirm the potential of introducing the new concept of "site specific road density" to support more scientific and objective decision-making in the process of road construction project.

In this paper I have considered the subject related with 'the identity of Korean linguistics.' When I have pondered upon the subject I found that all the researches should not be regarded as a part of Korean linguistics only because they followed the scientific methodology. Moreover, it isn't right to accept any of the studies of Korean linguistics only because they relied on the tenet of western linguistic methodology. Although till 1960's various western linguistic methods were introduced to Korean scholars and applied to account for Korean language, abruptly, since 1970's, most theories have inclined to follow tendency of American linguistic trend. Pupils who want to study modem linguistic theories prefer to study at the universities of America rather than other countries in Europe. However, it is necessary to blow that the history of American linguistics isn't really as long as that of European nations and that the humanities has developed fur a long time since the Greek period. If we attempt to contemplate the procedure of the invention of Korean alphabetic system (Hun-Min-Jung-Um) it will be easy to find the fact that the theoretic approaches used to observe and analyze Korean language in 15th century are as good as the most up-to-date theories which have been introduced recently. Therefore, I tried to show that the historical awareness of linguistic theories deserves special emphasis in order to understand the reality of Korean linguistics correctly.

It is well-known fact that woodworking activity could contribute in enhancing creativity, scientific problem-solving ability, spatial perception ability and prosocial behavior of children. However, there is little chance that children experience woodworking at home or in kindergarten. This study was conducted to know how much children and adults have done woodworking in there daily life and how they perceived children's woodworking activity. Woodworking activities for children (N=207, 5 and 6 year old kids) with adults (N=271, only fathers) were carried out in 10 kindergartens of Cheongju. Actually, the survey result shows that very few children and adults experienced woodworking in their daily life. 62.8% of children and 34.3% of adults surveyed responded that they had never done woodworking. However, the greater part of children and adults evaluated the woodworking activity positively. Over 95% of children surveyed responded that their woodworking activity was fun and they want to play woodworking again. Over 73% of adults surveyed responded that children's woodworking activity was safe, and over 99% of adults surveyed responded that they can recommend children's woodworking activity to others. In conclusion, the development of safe tools and programs for children's woodworking activity helps its spread and activation.

The latest educational curriculum in Korea started in 1997, and the 'Departmentalized Classroom System', which is a distinguishing modern concept compared with conventional pedagogy, has already been used in several high schools since 2009 and will be expanded to all middle school and high schools by 2014. However, most Korean schools are not yet physically ready to implement the new system. Moreover, despite many trials during the last three years, the characteristic and architectural function of a place called 'Home-base' is still vague and has caused many controversial arguments. In fact, a large number of home-base designs failed to accomplish their original task and there are counter evidences that shows reality was quite different over architect's personal and subjective radical plan. Therefore, this study seeks to introduce and objective scientific method based on an mathematical model of an optimized algorithm for planning a home-base area in a school design. The algorithm developed in this study is designed to determine the most efficient location for a home-base area to minimize the distance students typically need to walk.

WMSD occurs by accumulating the visible position and movements. Therefore, it is easier to prevent WMSD from occurring than other diseases when each employee is aware of the factors which cause WMSD. Hence, We need to develop exercise remedy, which can be done without using any exercise equipments and regardless places. The exercise prescription for those for LBP was to do the upper body exercise remedy twice in the morning and another twice in the afternoon and the spinal exercise remedy and the lower body exercise remedy once in the morning and once in the afternoon. We measured their maximum muscular strength every second week using a fitness machine so that we could compare the differences of the muscular strength of the test group and the comparison group. Therefore this research presented the fact that the exercise remedy is effective to prevent and cure LBP through a scientific test. And it confirmed that the exercise remedy by the Ergonomic exercise prescriptions is effective on LBP.
