Environmental Impact Assessment(EIA) in Korea has developed as a tool for environmental conservation and decision making since Environmental Impact Statement(EIS) preparation in 1981. For effective implementation of it, we do system development and method enhancement continuously. The recently introduced GIS (Geographic Information System) can integrate geographic and attribute data, which will be applied to scoping, assessment, and alternative assessment, etc. in EIA. This study has three major components. First, it explains building of EIA factors of natural environment, living environment, and socio-economic environment of the study area defined in EIS preparation regulation. Second, the study presents applications of assessment method concerning suitability analysis of landfill site using GIS. Finally, it shows integration of GIS and odor impact assessment. Based on these analysis, the study makes some recommendations and conclusions.

We propose an economic and facile method for the preparation of silica nanoparticles through a two-step process utilizing chlorosilane residues. Mixed chlorosilane residue was alcoholized with absolute ethanol as a first step to form tetraethoxysilane (TEOS). The TEOS was then utilized as a silicon source to synthesize silica nanoparticles in a sol-gel method. The alcoholysis process was designed and optimized utilizing the Taguchi experimental design method and the yield of TEOS was as high as 82.2% under optimal synthetic conditions. Similarly, the Taguchi method was also utilized to study the effects of synthesis factors on the particle size of silica nanoparticles. The results of statistical analysis indicate that the concentration of ammonia has a greater influence on particle size compared to the mass fractions of TEOS and polyethylene glycol (4.6% and 9.7%). The purity of the silica particles synthesized in our experiments is high, but the specific surface area and pore volume are small.

It was 1976 when the preparation of consolidated financial sheet was first prescribed in this nation. Since then, the prescription has been revised several times. Revised in April 1992, enforcement regulations of the Securities Exchange Act provided that every listed corporation has its consolidated financial sheets and an auditor's opinion about them attached to its business report. In other words, the outside audit of consolidated financial sheets became inevitable. The Act of the Outside Audit of Corporation was revised in December 1993 to provide that all corporations must prepare consolidated financial sheets and receive the outside audit of the documents beginning their settlement of accounts in December 1994. In case of overseas corporations, consolidated financial sheets and the Equity Law have been applied since their settlement of accounts in December 1995. Now those sheets must be prepared by all local and overseas corporations that involve relations of governance or dependence. The preparation and public notification of consolidated financial sheets has been settled as a system. This nation has not yet introduced consolidated tax return using consolidated financial sheets. Such tax return system is already being used by most of the world's economic powers such as U.S., Europe and Japan. This study shows that reduction in corporation tax is the biggest reason for avoiding consolidated tax return system, even though the system can facilitate the settlement of consolidated accounting. Consolidated tax return, which is being implemented in about 20 countries including U.S., needs to be introduced by this nation where consolidated financial sheets are publicly notified.

This study considered measures to support the establishment of surveying and spatial information in preparation for the unification of South and North Korea and the subsequent construction of national infrastructure. The organization identified and analyzed spatial information about North Korea, road and railway-oriented SOC construction projects, and examined the applicability of the latest technologies to narrow the technical gap with North Korea and quickly establish land spatial information. To prepare a support process appropriate for the situation in North Korea, technical and human support details and considerations were reviewed through a case analysis of spatial information construction for developing countries. In addition, the main result was "Presenting Efficient Utilization of Human Resources and Equipment for the Establishment of Spatial Information in North Korea," establishing an efficient utilization plan for the human resources and equipment needed in the support process based on technology support. It is expected that the South Korean government will minimize the negative impact on future land infrastructure construction by first conducting research in inter-Korean economic cooperation and national infrastructure construction and establishment of spatial information construction plans.

The failures of tailing dams have caused irreparable damage to human lives, assets and environment and this has ultimately resulted in great economic, social and environmental challenges worldwide. Due to this, investigation into mechanical behaviour of tailings has received some attention. However, the knowledge and understanding of mechanics of behaviour in iron tailings is still limited. This study investigates the mechanics of iron tailings from Nigeria considering grading, effects of fabric resulting from different sample preparations and the possibility of non-convergent behaviour. This was achieved by conducting series of one-dimensional compression tests in conjunction with index, microstructural, chemical and mineralogical tests. The materials are predominantly poorly graded, non-clayey and non-plastic. The tailings are characterised by angular particles with no obvious particle aggregations and dominated by silicon, iron, aluminium, haematite and quartz. The compression paths do not converge and unique normal compression lines are not found and this is an important feature of the transitional mode of behaviour. The behaviour of these iron tailings therefore depends on initial specific volume. The preparation methods also have effect on the compression paths of the samples. The gradings of the samples have an influence on the degree of transitional behaviour but the preparation methods do affect the degree of convergence. The transitional mode of behaviour in these iron tailings investigated is very strong.

In recent times, STEM graduates are confronting a decline in employment rates influenced by economic, social, cultural, and policy-related factors. Career decisions are closely linked to education, college experiences, and university settings. To comprehend the reasons behind the decline in STEM employment, it is essential to explore the relationships among these factors. This study aims to comprehensively examine differences in career motivation and career exploration behavior among 2,393 STEM undergraduates in Korea. Additionally, factors affecting career motivation and career exploration behavior were investigated. The findings indicate significant differences in perceived career motivation and career exploration behavior based on individual backgrounds and university characteristics. And analyzing the data, 37.8% of career motivation is explained by contextual supports, career barriers, individual backgrounds (grade, GPA), university characteristics (major fields, location), field to enter after graduation, and timing of job preparation. For career exploration behavior, 30.1% is explained by contextual supports, career barriers, individual backgrounds (gender, grade, GPA), university characteristics (major field, location), field to enter after graduation, and timing of job preparation. Practical implications underscore the need for tailored educational and policy support, considering individual backgrounds and university characteristics, to effectively address challenges faced by STEM graduates in the evolving employment landscape.

A cultural landscape results from a combination of human activities for resource-use and the response of nature to such artificial interference. Nature provides resources necessary for human life on the Earth in terms of his survival as well as living. Humanbeing has developed civilization using the benefits that nature provides. In the past, a harmonious relationship between mankind and nature had ensured sustainability of resource-use for human. We can find such facts from the existence of cultural landscape. However, rapid economic growth and a development-oriented logic caused from such socio-economic change led to the environmental crises and the depletion of various resources at global level. In the perspective of preparation for such problems, we investigated the background for establishment, function, and value of cultural landscapes, in which a dynamic equilibrium exists between a supply of natural resources and human needs. Furthermore, we discussed a new economic model including ecological consideration, a strategy for ecological management of environment, and a framework for transmission of traditional culture to new generations on the basis of a cultural landscape regime.

The great strategy of China has been changing depending on the time, change of surrounding environment and personality of leaders of the time. However, the process of the change was not the drastic change but has maintained the consistency through the course of modification and development. The great strategy of Mao Ze-dong was to have the objective in 'World Great Nation' with the facilitation of the 'Surpass Strategy' and 'Autonomy, Independence and Alliance strategy' to successfully build up the political great nation, but he entrapped China's politics and economy into the point of no return by excessive war preparation under 'The Principle of Inevitable World War', striving of rapid communism and other policies. The Deng Xiao-ping era also targeted for ‘World Great Nation’ but, unlike Mao Ze-dong, he had the foundation in the 'The Principle of Evitable World War' and undertook the ‘Peace and Development Strategy’ and ‘Peaceful Coexistence' to build up the advantageous surrounding environment for China to focus on the economic construction as the core of the nation by establishing ‘The Reform and Opening Strategy’ and 'Three-step Development Strategy‘ to have the successful soft landing of the Chinese economy with the astonishing economic development. The system of leader's group of China after Deng Xiao-ping succeeded the practical and realistic spirit of Deng Xia-ping, and based on the drastically grown economic strength, the great strategy of China is on the ‘The Great Reinvigoration of Chinese Nation’. This is one step further from the strategy of 'World Great Nation' of the past that it embraces all the minority races in China, Chinese economic sphere, foreign citizens of Chinese origin as well as Chinese residing abroad. China contemplates the time of making 'The Great Reinvigoration of Chinese Nation’ in 2050, 100 anniversary of the birth of new China.

Recently, Our society socioeconomically has faced the sudden changes. The retirement of the baby-boom generation is expected to become mainstream amid the falling birth rate and the aging society at the fastest rate in the world. As such a baby-boom generation is a core pillar of our economic development in the 1970s and 1980s, the rehiring difficulties after retirement, the insignificant old age preparation and their welfare and medical problem has become national issue. The government has implemented the policy for promoting the senior entrepreneur to participate productive economic activity by actively utilizing the senior's strength from this year. However, in spite of the importance of such a senior entrepreneur, the research to study the senior's desire and the concrete characteristics of the senior entrepreneur is nonexistence. Therefore, this paper empirically analysed the senior's concrete nature, entrepreneurial intention and the impact on the senior entrepreneurship, which is the core of the success entrepreneur and provided stimulating measure.
