The traffic accidents in large cities such as Pusan metropolitan city have been increased every year due to increasing of vehicles numbers as well as the gravitation of the population. In addition to the carelessness of drivers, many meteorological factors have a great influence on the traffic accidents. Especially, the number of traffic accidents is governed by precipitation, visibility, cloud amounts temperature, etc. In this study, we have analyzed various data of meteorological factors from 1992 to 1997 and determined the standardized values for contributing to each traffic accident. Using the relationship between meteorological factors(visibility, precipitation, relative humidity and cloud amounts) and the total automobile mishaps, and experimental prediction formula for their traffic accident rates was seasonally obtained at Pusan city in 1997. Therefore, these prediction formulas at each meteorological factor may by used to predict the seasonal traffic accident numbers and contributed to estimate the variation of its value according to the weather condition it Pusan city.

Effect of alkali $SO_3$ and $C_2S$ content and cooling condition of clinker on the formation of unstable alkali and cooling condition of clinker on the formation of unstable alkali was investigated. As a result alkali and $SO_3$ content of clinker were the main factors of unstable alkali formation and equation (7) in which the two factors were the variables showed a good agreement with the observed results. Water soluble alkali content of sulphate was decreased with increase of $C_2S$ content of clinker resulted by the increase of solid solution rate of alkali to clinker minerals. But change of unsatble alkali content accordint to the increase of $C_2S$ content was slight. A increasing tendency of ignition loss of clinker with increase of unstable alkali content was found.

It has been regarded as important in both academic and practical issues how to evaluate service quality. In addition international traveling will be growing due to increasing income and globalization. Thus, it is very important to measure the international airport's service quality properly. This study was conducted to identify the service quality factors which are utilized to measure international airport's service quality. According to the statistical analyses' results of this study, seven service quality factors and thirty two measurement items were found to evaluate international airport's service quality. They are some different from those which PZB(1988b) identified to measure service quality. This result implies that it is necessary to find the service quality factors reflecting the unique characters of the service organization when measuring service quality of a service organization.

Technology transfer from public research institutes is receiving an ever increasing importance in today's fast growing economy. Many factors have been cited as influencing the transfer performance. This study is focused on the strategy of institutes which is characterized by technology strategic factors and organizational/institutional factors. Methodologically, the technology strategy is represented by the information contained in applied patents, and the performance of technology transfer is indicated by the number of licensing contracts and royalty income. To further improve the contribution of public research institutes through technology transfer, I argue that individual institutes become more specialized in specific field and become more open to collaboration. It is also recommended that public research institutes gather together since it is easy to form the consortium of technology licensing office and it is not necessary to be located near the industrial field.

The accidents caused by dielectric instability have been increasing in power grid. It is important to enhance the dielectric reliability of a high voltage apparatus to reduce the damage from electrical hazards. To develop an electrically reliable high voltage apparatus, the experimental study on the electrical breakdown field strength is indispensable, as well as theoretical approach. In this paper, the lightning impulse breakdown characteristics considering utilization factors are studied for the establishment of insulation design criteria of an high voltage apparatus. The utilization factors are represented as the ratio of mean electric field to maximum electric field. Dielectric experiments are performed by using several kinds of sphere-plane electrode systems made of stainless steel. As a result, it is found that dielectric characteristics are affected by not only maximum electric field intensity but also utilization factors of electrode systems. The results are expected to be applicable to designing the air-insulated high voltage apparatuses.

Purpose - This paper aims to find and analyze factors that determine the flows of bilateral foreign direct investment in intra-ASEAN. It specifically focuses on the dimension of macro-economic, natural resources, human resources, and the quality of governance. Research design, data, and methodology - Data were collected from 64 bilateral relations between ASEAN nations from 2002 to 2013. Panel gravity model was utilized to find factors that determine the flows of bilateral foreign direct investment. Results - Significant factors were identified that determine the flows of bilateral foreign direct investment: GDP home country, GDP host country, real interest rate, distance, and total natural resources rent. Unexpectedly, natural resources have a negative effect. Conclusions - In a situation of increasing the flow of FDI among the countries of ASEAN, the government should control the interest rates and maintain good relations with nearby countries. The negative effect of total natural resource rents implies that ASEAN countries should not depend on their natural resources to attract foreign investments.

The franchise form of business relationship remains both relatively unresearched and under-conceptualized despite its current and increasing importance as a business form in modern capitalist industrial society. A franchise is the synergistic combination of a franchisee and franchisor working together to better serve customers, and the success of the franchise system is a function of how well the franchisee and franchisor perform, together and separately. Given the interdependent nature of franchise relationships, the franchise participants need to understand each other as well as the dimensions and dynamics of their franchise relationship. The purpose of this study is to investigate the various factors relationship. The purpose of this study is to investigate the various factors which influence the development of coopertaive relationship in business format franchising system. Based on commitment theory and marketing literature, eight antecedent factors are identified and nine hypotheses are developed.
