The purpose of this study is to examine the change in the beliefs of regular classroom teachers after participating in a gifted education lectures and practicum as well as the effectiveness of the lectures and practicum. Each teacher was asked to complete a pre-/ a mid-/ and post-journal, detailing their expected characteristics and then describing what occurred and how their initial expectations were altered. The teachers mentioned high thinking skills, creativity, fast problem solving skills, and a lack of communication skills as intellectual characteristics of gifted students and high motivation and task commitment as social characteristics. They mentioned the characteristics in textbooks on pre- and mid-journals, but presented their observations in post-journals such as lack of communication skills, competitive spirit, and frustrations. The study found that teachers broadened their view of giftedness, recognized the need to adapt instructions for gifted students, realized the necessity of knowing the students to differentiate instruction patterns, and emphasized teaching-learning strategies for the gifted. These results contribute to the promise of having regular classroom teachers engage in a field experience with gifted students to supplement discussions about gifted education lectures.

A study was conducted to evaluate the weed population as affected by repeated application of fertilizers for 15 years (nonfertilized, PK, NK, NPK, NPK+Compost, NPK+Straw and NPK+lime). Alopecurus aequalis authority did not grow at all without P application and lime reduced the population of A. aequalis. Total number of weeds were the largest at 5-10cm soil layer and increased by application of compost and straw. Monochoria vaginalis dominated in NPK+compost and NP plot. Scirpus hotarui dominated in NPK+straw. Both Eleocharis kuroguwai and Potamogeton distinctus dominated in nonfertilized plot. Numbers of M. vaginalis and S. hotarui were larger low pH 6 while that of E. kuroguwai and P. distinctus at pH 6 to pH 7. Incidence of M. vaginalis and S. hotorui was great at pH's lower than 6, while E. kuroguwai and P. distinctus favored pH's ranging from 6 to 7.

The objective of this study is to evaluate the effect of the water quality improvement by water discharge through dams and to provide a benefit estimation methodology, taking domestic situation into consideration, by the replacement cost approach analyzed with a sewage treatment plant instead of an alternative dam. To this end, facility that alternates a dam must have same functions of the discharged water from the dam and the two facilities must be able to be compared objectively. To estimate the benefit, estimation methodology of alternative facility's cost is established and criteria of cost.benefit analysis that are duration period and ratio of large scale repairing expense was presented. As a case study, the water quality improvement benefit of Song-Li-Won dam was evaluated, which is planned to be built on Nae-Sung stream in Nak-Dong River system. The results of applying this methodology to Song-Li-Won dam are 644,006 million won of the annual average discharge and 1,351,526 million won of maximum discharge. The usage of the framework in this study is expected for estimation of water quality improvement benefit in case water quality improvement project is performed.

We investigated middle school students' awareness of Han-style(Korean cuture) in order to promote it, and developed and applied the Teaching-Learning Lesson Plan according to the traditional clothing culture contents related to Han Style. We selected 5 major fields representing Han Style including Han-gul(Korean alphabet). Han-sik(Korean food). Han-bok(Korean traditional clothes). Han-ji(Korean traditional paper), and Han-ok(Korean traditional house). We analyzed the contents of the food, clothing and shelter in 6 types of high school testbooks under the revised 7th national curriculum, and chose seven traditional clothing-lifestyle culture contents. Also we developed 14-period processes and materials(9 for teachers. 9 for students and 3 for and applied it to usual classes. The mean score of middle school students' awareness of Han Style in the post-test was significantly higher than that in the pre-test. Students evaluated it positively that the classes could raise the pride on the Han-culture and provoke the interest in it through the direct experiencing activities. We suggest that the various themes on Han-style should be developed, and the theoretical classes on the identity as well as the experiencing activities on it.

Port industry has achieved a remarkable growth with a help from increase in container shipment and above all, transshipment that reflects international competitive power of Port industry amounts to 36% of the national harbor shipment. Therefore, this study speculates the impact of Port industry on national economy using the inter-industry relation table. As it considers the reason why international competitive power in Port facilities decreased as absence of investment, it is to present an effective investment plan for Port industry. Though Port industry as one of main national key industries play an important role in production of national economy, it has been evaluated as having relatively less importance. And when Port industry is managed independently, relying on foreign countries without improvement, price increase due to improper agreement of foreign enterprises and problems relating to securing safe transportational vehicles will have tremendous impact on national economy. And they should try to create added-value and support re-export of the exported and imported shipment through their processing and packaging by making Port zones bonded area. production of national economy, it has been evaluated as having relatively less importance.

It has been widely accepted that the environment is an important determining factor of human health. Appreciating the relationship between the environment and human health, Korean government has begun to deal with issues of environmental health. The government proclaimed the year of 2006 to be the first year of Environmental Health and established "The Environmental Health Plan for the next 10 Year". In order to achieve the goals in the plan, there are necessary considerations such as support systems for environment health related research, investigation, law, institution, administration, and so forth. This study suggests basic principles required to establish a legal regime of environmental health which is to implement the environmental health policies in Korea. Several cases of foreign legislation and policy relevant to environmental health are reviewed. Also, existing related legal system in Korea are analysed considering legal and institutional elements for establishing an effective environmental health policy. The main purpose of amending legal system related environmental health is to protect both public health and the soundness of ecosystem. To reach the goals effectively, the concept of 'environmental health' should be clearly established and presented. In addition, an advanced prevention system, including investigation and prevention of the cause of environmental diseases and risk assessment based on the precautionary principle, are substantial in the environmental health legislation. Also the environmental health law should guarantee public participation in decision making as well as the first consideration of susceptible or vulnerable population. This study concludes that the expected legislation related to environmental health should be a nonnative instrument not only for integrating each environmental protection scheme but also for establishing and implementing the policy.

The earth science curriculum and textbooks of the secondary school in South Korea and North Korea were analysed comparatively with the modified TIMSS curriculum frameworks. In the secondary school of North Korea, earth science is not provided with separate subject, but partly taught in geography. Geography is taught by two hour per week in the first to fifth grade of secondary school. Especially the first and the fifth grade geography are deeply related to earth science. The major aim of earth science education in South Korea is to develop creative problem solver having with interest and curiosity in searching natural phenomena and with basic science concepts and inquiry process skills. But on the other hand the aim of geography education of North Korea is to cultivate communist revolutionists who are faithful to IL-Sung Kim and Jung-IL Kim. In both Koreas the category of 'earth feature' and 'earth process' are dealt a lot, but 'earth in the universe' is rarely taught in North Korea, which suggests that separate subject of astronomy is instructed in the North. Generally the scope and sequence of earth science of North Korea comes under those of middle school of South Korea. Especially discrepancy in level of meteorology and astronomy area between North and South Korea is great.

The purpose of this study was to investigate the suitability of elective of the 2009 revised high school science curriculum. This study surveyed 911 students in 126 high schools by using proportionate stratified sampling. Each participating students carried out the on-line survey comprising 13 items about personal and academic suitability. The result of analyzing the response of the questionnaire were as follows. First, there were deviation of study-load, depth, difficulty, etc. between science elective I and II. Second, even though 'science' subject was developed as a subject for improving scientific literacy, it was found that it was considered difficult next to Physics I. Besides, it showed 'science' subject could not function properly to improve the ability to communicate. According to the results of analyzing the degree of interest in science elective, it can not be determined 'no interest in subject' is from the reason of difficulty or large amount of contents to memorize. The results of this study will be useful to provide suggestions for the improvement of next high school science curriculum and textbooks.
