Today the concept of corporate social responsibility has become an essential element for coexistence of corporations and the society. In this study the impact of four responsibilities of business organizations proposed by Archie Carroll (economic, legal, ethical, and discretionary) on customer loyalty through the mediating effect of trust and company-consumer identification is analyzed. A questionnaire survey was conducted for four well-known Korean companies (Dong Suh Food, LG Household and Health Care, Samsung Electronics, and Hyundai Motor). After factor analysis, legal and ethical responsibilities were grouped as the same factor, thus three social responsibilities were finally used for hypotheses testing. Major findings were as follows: First, economic responsibilities had positive impact on honesty trust, professionalism trust, favorableness trust, and company-consumer identification, Second, legal/ethical responsibilities were found to have significant effects on honesty trust, favorableness trust, and company-consumer identification. Third, in the case of discretionary responsibilities, professionalism trust, favorableness trust, and company-consumer identification were revealed to have a significant positive relationship. Fourth, only two trust variables (honesty and professionalism) and company-consumer identification had positive influence on the loyalty of customers. These findings are expected to help decision makers to set up corporate objectives and choose action items for corporate social responsibility. At the last part, implications of the study and future research directions were discussed.

Excel is a commercially available computer program that is used worldwide. Excel is widely utilized; it is helpful in household ledgers, corporate tax calculations, management of academic grades or reports, etc. However from the beginning, inaccuracies and errors in calculations have constantly been identified, so the program is updated regularly. Decimal-to-binary conversion is a simple and repetitive task. So, use of a computer program to do this calculation is suitable. Errors in decimal-to-binary conversion are surprising and are not easily understood. Therefore, it is important to identify the flaws in Excel, which unfortunately still exist today. It is necessary to determine the cause of this type of error, and I hope for a fix to be implemented quickly.

Starting her business operation on January 5 2007, Taiwan High Speed Rail(THSR) shapes a new time-space frame for Taiwan western corridor, where more than 90% of national population lives around and more than 95% gross domestic product created from. Comparing with the four-hour traveling time by highway before 2007, THSR reduces the time required to one and half hours from Taipei to Kaohsiung. It will not only benefit the communication along the island from north to south, but also change the location advantages/disadvantages for all cities in these regions. Therefore, this paper establishes a spatial computable general equilibrium model(SCGE Model) to simulate the economic effect of High Speed Rail(HSR). This SCGE model divides Taiwan economy into fifteen geographic regions and thirteen industries. Each region has three sectors: household sector, transportation sector, and industries sector. Following the behavior function of economic theories, the general equilibrium can be achieved simultaneously. Thus, gross regional product (GRP), capital formation, employment income and welfare/utility level can be all observed by calculating the different economic result between cases with-/ without-HSR. Besides, this model presents the social welfare benefit from HSR operation, the polarization phenomenon among regions and within certain region, unbalance distribution of welfare along the HSR line, and industries development divergence among regions etc. These major findings should be useful for regional development policy making.

The compressor is used for many fields not only in the industrial sector, but also as a general household product. The energy consumption required for the compressor operation is very large. The reciprocation compressor is widely used as an air compressor. Regarding the reciprocating air compressor, the discharge of the gas compacted by the method of compressing the gas by using the oscillation of the piston is generated by the piston reciprocation 1 church 1 number. When compressing after compressing the air by the oscillation of the piston, the marine reciprocating air compressor is the vibration generated in the compressor and surrounding structure due to the energy of the generated inertia. If the effect of these harmful elements can be reduced, it supports the service of the vessel. In addition, accidents generated by the noise of the vibration can be prevented. Therefore, in this research, firstly, the structural analysis of the piston part was performed, the safety factor in all results was drawn based upon this, and the reliability of the interpretation was examined in order to create the optimal design for the air compressor.

Heat exchangers are commonly used in practice in a wide range of application, from heat and air-conditioning system in a household, to chemical processing and power production in large plant. An Experimental study was conducted to investigated the fluid flow and heat transfer around four circular cylinders of in-line in a cross flow of air. The local and average heat transfer characteristics for tube banks are investigated in the present study. Heat transfer in a heat exchanger usually involves convection in each fluid and conduction through the wall separating the two fluid. The in-line pitch ratio was in the range $1.5{\leq}L/d{\leq}4.0$, where L is the center distance and d the cylinder diameter, and in the Reynolds number $8,000{\leq}Re{\leq}50,000$. The local and mean Nusselt numbers were estimated. Subsequently, the heat transfer characteristics of four circular cylinders are found to exhibit a strong dependency upon the separation point of their upstream cylinders.

This study found a relationship between the characteristics of the elderly with disabilities and extra health care monthly costs caused by disability and suggests methods for effectively managing health care spending of the elderly with disabilities. This study used data from the 2011 Survey on the Disabled conducted by the Ministry of Health and Welfare and the Korea Institute for Health and Social Affairs. The results of the analysis indicate that the relations between the socio-demographic characteristics of the elderly with disabilities and extra health care monthly costs caused by disability of the elderly are influenced by factors such as gender, age, members of the household, average monthly income and type of health insurance. Elderly people with disabilities spend too much for their medical care. To solve this problem, the government needs to find a variety of policy approaches to improve administrative procedure, establish a medical delivery system and enhance health care services.

Objectives : This study tried to examine whether there is any difference between the middle-aged men and women in terms of the effect of health-related and oral health-related characteristics on their depressive symptoms (PHQ-9). Methods : We used the 2nd year data of the 6th session of the National Health and Nutrition Survey of 2,008 adults(aged40~64 years) for fulfilling the research objectives. Results : The analysis showed that among middle-aged male and female respondents, household income, subjective health conditions, and stress perception among health-related characteristics had common elements affecting their depressive symptoms. The self-reported oral health conditions affected depressive symptoms for male respondents. On the other hand, chewing problems and contraction of periodontal disease affected depressive symptoms of female respondents. Conclusions : Thus, it is necessary to consider the effect of sex in the relationship between health-related and oral health-related characteristics, and to make efforts to develop differential programs to manage and prevent depressive symptoms among men and women.
