Recently, the interest in artificial environment made by mankind as well as natural environment has been increased. This interest in the environment began to be reflected in the physical education, which environmental problems affect modern people's living quality as a crucial factor affecting directly or indirectly our life. Furthermore, since we entered the era of mass sports the physical education subject has dealt with destruction of natural environment by constructing golf courses, ski slopes, etc., destruction of ecosystem by water sports, mountaineering sports, aero sports, etc., and noise pollution near the sport facilities. Therefore, the purpose of this paper is to examine the means to reinforce environmental education in many ways in the physical education concerning environmental problems. For this purpose this paper analyzed the contents of the 7th curriculum for physical education which can be thought to be teaching materials for environmental education, and described the contents in detail. Also, this paper established the orientation and goals of environmental education in the physical education subject and examined some important teaching and learning methods. In addition, this paper suggested some considerations concerning environmental education and a textbook model for the development of physical education textbooks connecting with the 7th curriculum for physical education, which is to suggest a means to connect physical education with environmental education smoothly. The physical education has an attribute that its activities like swimming, climbing mountains, and camping are performed outdoor. The physical activities in the physical education are, of course, performed in the environment, so we had better implement the environmental education including such physical activities at the same time with physical education. Also, there should be efforts so that the education through environment, the education about environment, and the education in the environment can be implemented along with the physical education.

With the development of location-aware technologies and the activation of smart phones, location based social networks(LBSN) have been activated to allow people to easily share their location. In particular, studies on recommending the location of user interests by using the user check-in function in LBSN have been actively conducted. In this paper, we propose a location recommendation scheme considering time and user activities in LBSN. The proposed scheme considers user preference changes over time, local experts, and user interest in rare places. In other words, it uses the check-in history over time and distinguishes the user activity area to identify local experts. It also considers a rare place to give a weight to the user preferred place. It is shown through various performance evaluations that the proposed scheme outperforms the existing schemes.

The mutual credit of Fisheries Cooperatives is reciprocal financing bring overs and shorts to settlement themselves by filling each other's needs among feeble fishermen economically. The spread of mutual credit through Fisheries Cooperatives reduces private loan dependence and private loan interest rate at fishery village, and that fills up policy financing being restricted by working scale. And seeing movement side of Fisheries Cooperatives, it has done an under board to settle self-supporting foundation of primary fisheries cooperatives early. The mutual credit deposit shows about 53 times increase past an interval of a ten years. This increase rate is an epoch-making record being unparalleled in other banking facilities except Fisheries Cooperatives. Then being unparalleled increase rate, time and savings deposits increase has been contributed a great deal than demand deposits. Thinking important function factors as mutual credit growth, we can classify interior and exterior factors. The exterior factor is income of fishery household in some measure, interior factors are the high deposits interest rate and the enlargement of facilities organization. As these, they have been in a better factors, also have been a restriction factors. The restriction factors are conflict cancellation between mutual credit and them bring into existence a village vault, mutual savings and finance companies, private finance. For the sake of continuance growth rate in mutual credit as past, we should eliminate restricted factors in growth. On the other hand the better factors in growth should be act upon affirmation side continually. Consequently under circumstances not to an amicable settlement bring the fisheries fund demand as policy financing, we should do continuous and sound development of fisheries financing by means of putting in good order of fisheries cooperatives mutual credit. Surveying a problem from these viewpoints, when we study more deep and a full into a subject about growth project of mutual credit, we think to expect continuous growth in mutual credit of Fisheries Cooperatives.

AI (Artificial Intelligence) has attracted interest as a key element for technological advancement in various fields. In Korea, internet companies are leading the development of AI business technology. Active government funding plans for AI technology has also drawn interest. But not everyone is optimistic about AI. Both positive and negative opinions coexist about AI. However, attempts on analyzing people's opinions about AI in a quantitative way was scarce. In this study, we used text mining on SNS (Social Networking Service) to collect opinions about AI. And then we performed a comparative analysis about whether people view it as a positive thing or a negative thing and performed a comparative analysis to recognize popular key-words. Based on the results, it was confirmed that the change of key-words and negative posts have increased through time. And through these results, we were able to predict trend about AI.

The revised curriculum in 2007 adds an open inquiry approach to increase students' creativity and interest in science. Because it is the first time for elementary students to perform the open inquiry due to the national curriculum, it is essential that teachers give students' successful experiences in order to build a positive impression about inquiry activity. The purpose of this research is to develop and apply the open inquiry program. The research findings are as follows: First, we analyzed the students' traits of open inquiry ability during the program. The third and fourth grade students showed weakness in operating and inquiring abilities. They also feared failure and were unable to concentrate in classes which were based on explanation or discussion. When students had unexpected results, however, their inquiring abilities and creativeness increased considerably. Additionally there were some students who were stressed during the science-inquiry activity, due to no interest in science and an inability to think scientifically. Second, we developed an open inquiry program for elementary students. The program was modified, reflected upon the students' traits during open inquiry in class. Through repeated feedback like this, we completed the program. Third, for those who studied in the lessons there was a meaningful change in students' science inquiry abilities and abilities to perform 'formulating a hypothesis' and 'the control of variables'. These students' level of self-inquiry performance improved steadily. Moreover, they obtained a strong attachment to their inquiry and understood the method of quantitative experiments.

In preparation of the increase in the domestic debts and the rise in the US interest rate, the Korean government has started to strengthen the regulation on the property market since 2017. So, it is likely that the sales in the domestic construction market would be decreased. Even in the overseas plant projects market, as there has been the continuous increase in the cost and the resulting increase in the losses, it looks hard for the large construction companies to keep their credit ratings as they are now. This study is designed to check Korean government's property policy and any possible problems caused by the overseas and domestic economic environment, which include the property market policy, interest rate, rise in the property price and lackluster sales in housing market. It showed the change in the credit ratings by finding out the sales, work capability, sales in non-governmental projects, operating profits and PF contingency liabilities. For this study, the questionnaires were sent to 30 practical experts to analyze the effect of the risk factor on the outside credit rating of large construction companies.

In fisheries financing before the liberation of Korea, the accommodation of funds through modern monetary facilities was hardly benefited to most of small-scale Korean fishermen except Japanese fishermen living in Korea and some large-scale Korean fishermen. In fact, since Korean economy was only in the beginning stage of capitalism free from natural economy in the end of Yi Dynasty, it was natural that the supply of funds should be lacked. But after the opening of ports in Korea, the external shapes in Korean society were slowly changed according as heteronomous modernization was pushed forward by means of western capitalism and the intentional invasion of Japanese was gradually weighed. Thus all kinds of fishing equipments and technique were developed by dint of modernization, and modern monetary facilities also came into being. But most of Korean fishermen were hardly benefited by modern monetary facilities. Fishermen who were faced with destitution of funds were forced to rely upon high interest loans in order to make a living or maintain fisheries, and they were severely exploited by usurers. The situation was the same in the period of Japanese imperialism. Japanese felt the necessity of advancement of Korean fisheries and established fisheries institution suitable for all kinds of colonial fisheries policy toward Korea so that they could build up the foundation according to the development of capitalism and carry out the Russo-Japanese War and the Sino-Japanese War. There were a series of bottlenecks in financing on account of the deficiency of fisheries institution in the beginning of Japanese imperialism, but the financial pressure was lightened because the arrangement of institution greatly contributed to the smoothness of fisheries financing in the latter part of it. Despite such improvement of financing, the benefit of funds could not equally reach to all the fishermen. It only reached to Japanese fishermen living in Korea and some large scale Korean fishermen. Thus most of korean fishermen could not free themselves from destitution of financing and the pressure of high interest loans. This phenomenon took place because Korean fisheries had the antinomic characteristics that financial restriction was excessive owing to the industrial speciality of fisheries, on the other hand there was a large financial demand in fisheries in the character of industry.

The purpose of this study was to evaluate the actual state of middle and high school student's behavior about the use of oral hygiene devices for developing appropriate educational objectives to improve oral health. Data were collected by questionnaires from 445 middle and high school students in Jeolla-Bukdo, from April 20 to May 10, 2009. Surveyed data were analyzed by descriptive statistics, ${\chi}^2-test$ and t-test using SPSS V11.5 program. In the event of those who didn't use oral hygiene supplies, the largest group didn't use the devices since they didn't know about them well. Regarding links between experience of using oral hygiene devices and concern for oral health, those who received that education showed more interest in oral health, and the students who felt the need for that education had more interest than the others who didn't. The results of study suggest how to encourage students to utilize appropriate oral hygiene supplies and to help facilitate the development of school oral health education programs and the promotion of school oral health.

This study was carried out to investigate the perception, preference and usage of Korean festival foods of women according to age in Busan. The survey was conducted from October 15, 2012 to November 30, 2012 using questionnaires and the data were analyzed with the SPSS program. In general, younger women (20~30 years old) had a lower interest in Korean festival foods than slightly older women (40~50 years old). Most of women over 40 years of age prepared Korean festival foods at home, but many who were in their 20's (45.9%) and 30's (41.1%) obtained their foods from family and relatives. Overall, 62.5% of the subjects wanted to inherit Korean festival food from family and relatives. The dissemination of information and recipes of Korean festival foods were needed for succeeding to Korean festival foods. The taste score was significantly lower for women in their 20's compared to those over 40. Women under 40 reported a lower ease of cooking compared to women over 50. Tangguk (4.93) on Seollal showed the highest perception degree in the order of Namul (4.91), Tteokguk (4.90), and Sikhye (4.90). Jeon, Yaksik, Sikhye, and Gangjeong were the most highly preferred in every group. The preference degree of Pajeon was significantly higher in women under 40 than in those over 60. Tteokguk and Tangguk were more highly preferred in women in their 30's and 40's compared to the other groups. There was a significant positive correlation between preference for festival food and education level, degree of knowledge, degree of interest, will for inheritance, and will for learning (P<0.01). In conclusion, festival foods rich in local tradition should be developed, publicized and used to educate others. The simplification of cooking methods and the development of processed foods are needed to pass on the traditional food culture of Busan.
