As economy is growing and income level is increasing, more people are pursuing relaxation and leisure in their life. As the sports market in Korea is flourishing, sports wear companies have begun to focus marketing their brand by carefully selecting advertising models in order to get more exposure for their brands. The purpose of this study was to analyze, the effects of the advertising model types had on the company's brand recognition, and consumer subjectivity on consumer's preference and purchasing intention were studied. The subjects for the study were 260 men and women in their 20~30s living in Seoul and Gyunggi province. Three-way ANOVA was conducted for the data analysis. The results showed significant interactions between the three independent variables on preference. Although there were various advertising model types due to the improvement of media, (brand advertisement employing) the well known celebrity model was more effective for raising consumer brand awareness compared to non-celebrity models.

The number of vehicles applied diesel engine are rapidly rising for fuel economy. Accompanying this trend, application of an after-treatment system is strictly required as a result of reinforced emission regulation. The Diesel Particulate Filter (DPF) system is considered as the most efficiency method to reduce particulate matter (PM) by car makers but also in retrofit market. In recently, various kinds of partial flow DPF are widely used for proper filtration performance and reducing of pressure drop but it is difficult to define the characteristics of these filters because the filtration mechanism is obscure according to the status of these systems. In this paper we investigated the characteristics of cell open type DPF according to the status of filter especially, PM loading. The PM loading mass in the p-DPF are predicted from increase of differential pressure of DPF and the trend of filtration efficiency so that we can measure filtration efficiency and Balance Point Temperature (BPT) of this p-DPF according to PM loading.

The number of vehicles applied diesel engine are rapidly rising for fuel economy. Accompanying this trend, application of an after-treatment system is strictly required as a result of reinforced emission regulation. The Diesel Particulate Filter (DPF) system is considered as the most efficient method to reduce particulate matter by car makers but also in retrofit market. In this paper we discussed the optimization of active regeneration timing by comparing the fuel consumption from back pressure caused by PM loading and from active regeneration. The effects of back pressure of DPFs during PM loading, active regeneration condition and engine emission(PM) on additional fuel consumption are experimentally investigated and the proper regeneration timings according to DPF systems and fuel loss for 160,000km are determined.

As diesel engines have high power and good fuel economy on top of less $CO_2$ emissions, their market shares are increasing not only in commercial vehicles but also in passenger cars. LNT, urea-SCR and combination of them have been developed for after-treatment of the exhaust gas to reduce NOx on diesel vehicles. The aim of this study is to investigate the $NH_3$ generation characteristics of LNT catalyst downstream. It was found from the experiments of the LNT catalyst that $H_2$ was useful as a reductant in SCR catalyst because it can enhance the de-NOx performance and improve $NH_3$ selectivity. The $NH_3$ generation of the LNT, when hydrothermally aged at $900^{\circ}C$ for 18 hr, increased to about 90ppm at $300^{\circ}C$ due to Pt sintering and Ba agglomeration. LNT catalyst was most sulfur poisoning at $500^{\circ}C$. The $NH_3$ slip increased due to the reduction of residence time according to SV increase.

The construction market has a major impact on the overall United States economy. Recent statistics estimate the gross domestic product (GDP) of the U.S. construction industry at some $416.4{\$}$ billion dollars, representing approximately $4.5\%$ of the U.S. GDP. Because the business environment in construction is highly competitive, the participants in the industry must improve their performance and processes to survive. Hence, Benchmarking has been generating interest in the construction industry. This paper provides an overview of the CII Benchmarking and Metrics Program. Following some background and a descriptive discussion of the database, an abridged presentation of result of data analysis. The adoption of benchmarking in Korean construction industry can be another opportunity to improve Korean construction industry.

In this article, since the financial crisis, Korean employment movement to service market, productivity gap between manufacturing and service industry was significant compared with other countries. The results from productivity decomposition show that negative structural changes, which employment increase is contrary to the productivity, have been intensified since the financial crisis. It is caused from a different developing pattern. While the proportion of employment was reduced, productivity has improved in manufacturing industry. While the developing was due to the high increase of the employment proportion in service industry, productivity was not improved significantly. This tendency is clearly revealed in international comparisons. In Korea the negative trend of structural changes in service industry are intensified compared to manufacturing industry after the financial crisis.

This paper study on the effect of the removal or reduction of the tariff on Korea-India trade by CEPA between Korea & India and then examines the effects of increased exports & imports to Korea on India. Despite the analysis is based on data over a short period of time, this paper shows that CEPA between Korea & India has substantially increased Korean exports(42.7%) and imports(37%) to India in 2010. It is also shown that CEPA between Korea & India has had a considerable impact on market. As a result can be summarized as follows. The potential fields of expanding the trade between the two countries due to the tariff concessions of the removal or reduction. Consequently the effect of the removal or reduction of tariff will be low our expectation but CEPA between Korea & India would have a positive effect on Korea's exports to India in the long term. This paper has examined the impact of CEPA between Korea & India on general economy. It needs a further study to estimate trade diversion effect of CEPA and to find out the impacts on specific industry.
