Tensile stress and strain of rear by shock wave become the cause of rear side scabbing of concrete subjected to high-velocity impact. Improvement of flexural and tensile performance by fiber reinforcement has great effect on the suppression of the rear scabbing.

In this study, local fracture of concrete was evaluated through high-velocity impact test. As results, increase of bending tension performance by fiber reinforcement did not affect penetration depth Control, but it decreased rear side fracture thickness and diameter. Therefore, it was observed that fiber reinforcement decreases scabbing limit thickness.

In this study, impact of high-velocity projectile by mixing steel fiber, polyamide, nylon, polyethylene fiber which have different shape and properties respectively. Scabbing is restrained because of micro-crack caused by the shock wave offset effect and energy dispersive of synthetic fibers are mixed populations.

The purpose of this study is to establish a mathematical equation to evaluate the compressive strength of concrete from the measured impact resonance test values(Ed). The correlation was made between the measured and evaluated compressive strength values and the correlation was quite strong.

According to recent meterological disasters, social awareness for safety of infrastructure is heightened by increasing natural disasters such as Fukushima accident, landslide of Umyeon mountain. Also scale of landslide is increased in Korea but safety review of dam is insufficient. In this study, we reviewed data(reservoir capacity, type of dam, danger map of korea forest service, satellite pictures, geologic map, etc.) and conducted site investigation whose the area is the most dangerous. Based on the results, we choose the most dangerous dam and analysis site close examination, slope stability analysis, scale of debris flow, etc. As a result, we will conduct measures establish on reinforcement and final evaluation of landslide's hazard.

Results - The results of the study supported the statement that there exists a positive relationship between teachers’ professional development and students’ performance. Conclusion - Based on the findings it is surmised that, in order to create a clear learning relationship between teachers and students, management must support the teachers through peer group discussions and training opportunities, and should chooseteachers who can make students pursue the learning of subject knowledge with practical implementation

The paper deals with the impact of the product distribution and information technology sectors on energy resource use, carbon emissions and economic growth by examining the long-run equilibrium relationships and Granger causal relationships among these variables in South Korea. The quarterly time series data from the first quarter of 1970 to the third quarter of 2010 (163 observations) are collected and retrieved from the Bank of Korea database. The paper examines the long-run equilibrium relationships using cointegration techniques and Granger causality using vector error correction models. Test results indicate a long-run equilibrium relationship exists among these variables. In testing directional causality, both the product distribution and the information technology sectors show direct effects on economic growth but only marginal effects on carbon emissions.

Since 2008 the world financial crisis, implemented by the America government monetary payment policy has brought increased liquidity, but the decline in the dollar value of the decline of the export competitiveness of the countries all over the world, especially since 1980, Japan's economy is facing difficulties great, plus American monetary easing, the Japanese economy and more faded. Since 2012 October the Japanese far right parties, Liberal Democrat Andouble government came to power, the Japanese government yen devaluation, depreciation of the yen to Japanese economic recovery, but the Asian countries has been on the Japanese export oriented development mode, and the types of export commodities are more or less the same, therefore, the depreciation of the yen after Japan's exports have the great competitiveness, but at the same time the rest of Asia's export competitiveness has declined. The yen short-term the biggest damage country is South Korea, then China, but the total economic China than South Korea, namely the yen's depreciation on Chinese is very large, especially Chinese ships, iron and steel, auto parts and other heavy industry. Chinese are developing countries, the developing countries China heavy industry development is essential in its economic growth on the road, the developed countries of western countries and Japan have to rely on the development of heavy industry, heavy industry development level decides the development level of a country, RMB appreciation has lasted one and a half years, from a in the short term, has little effect on the Chinese economy. To observe effects of yen depreciation consequences, and through this thesis research the effect of the devaluation of the yen Chinese industry and explore the impact of future devaluation of the yen Chinese.

Korea companies in China often encounter a series of problems such as Chinese employees frequent job quitting，antipathic to authoritarianism management in Korean companies, mistrust and labor disputes caused by increasing labor disputes and etc. through a deep analysis I found the root to these questions is the cultural differences between China and Korea. Traditional korean culture emphasizes community consciousness, the features of which are authoritarianism, collectivism, and exclusivecronyism. in addition, hierarchical army culture has great impact in Korean society and culture, therefore, Korean companies are featured as collective communities with clear hierarchical employment system. different from korea, as enforcing Communist Party and collapse of feudal Confucianism, hierarchy culture emphasizing differences between gender, age and social level is diminishing, instead, equal consciousness is growing,"everyone is equal" is greatly emphasized in human relations. Korean companies in China needs to get rid of Korean-centered thinking mode and rethink more about Korean way of management, which means to improve parental authoritarian management and use "democratic" management fitting Chinese present situation. creating equal working environment and enhancing democratic communication is important in decreasing cultural differences and increasing humane trust. therefore effective human resources management can be realized.

Purpose The purpose of this – study is to empirically investigate the impact of capital structure on firm performance. Research design, data, and methodology – This study examined the impact of capital structure on the performance of cement companies listed on the Karachi Stock Exchange during the period 2009-2013. The authors hypothesize that there is a negative relationship between capital structure and firm performance. To examine the association, the authors run a Pearson correlation and multiple regression analysis. Results – Results reveal a strong negative relationship between debt to asset and firm performance variables (GPM, NPM, ROA, and ROE). Further, there is a positive relationship between debt to equity and firm performance variables (GPM and NPM), anda negative relationship between debt to equity and firm performance variables (ROA and ROE). Moreover, capital structure variables significantly impact firm performance. Conclusions – This study concluded that financial analysts and managers should emphasize on the optimal level of capital structure and efficient utilization and allocation of resources to achieve the targeted level of productive efficiency in business

Life Cycle Assessment(LCA) has been carried out to evaluate the environmental impacts of glass bottle recycle. The LCA consists of four stages such as Goal and Scope Definition, Life Cycle Inventory(LCI) Analysis, Life Cycle Impact Assessment(LCIA), and Interpretation. The LCI analysis showed that the major input materials were water, materials, sand, and crude oil, whereas the major output ones were wastewater, CO2, and non-hazardous wastes. The LCIA was conducted for the six impact categories including 'Abiotic Resource Depletion', 'Acidification', 'Eutrophication', 'Global Warming', 'Ozone Depletion', and 'Photochemical Oxidant Creation'. As for Abiotic Resource Depletion, Acidification, and Photochemical Oxidant Creation, Bunker fuel oil C and LNG were major effects. As for Eutrophication, electricity and Bunker fuel oil C were major effects. As for Global Warming, electricity and LNG were major effects. As for Ozone Depletion, plate glasses were major effects. Among the six categories, the biggest impact potential was found to be Global Warming as 97% of total, but the rest could be negligible.

This experiment was carried out to establish the optimum cutting time, plant growth regulator, and bed-soilfor rooting by greenwood cutting of Schisandra chinensis. Approximately 7㎝ long-shoots of greenwood cuttings weretransplanted by various cutting times, plant growth regulators, and bed-soils in the plastic-film house. The rooting rate ofgreenwood cutting was 12.5% in the April 5th, 73.5% in the May 8th, and 75.5% in the August 5th. The number and lengthof primary root in greenwood cutting were more in the early May than those in the early August. For mass propagation ofSchisandra chinensis. using greenwood cutting, shoots were treated with plant growth regulators on May to increase rootingrate. Rooting rate was 100% with IAA 50㎎/ℓ,92.9% with NAA 100㎎/ℓ,and NAA 1,000㎎/ℓ,for 60 min. To selecteffective media for rooting, various medias for bed-soil were treated by single and mixture form for 100 days after cutting.Rooting rate was 91.8% in the single treatment of peat moss or decomposition of granite soil, and this result was better thanthose in other treatment. The treatment by 1:1 mixture of peat moss and horticulture bed soil was rooting with 94.0% bestrooting rate.
