This study empirically analyzes the impact of inventory management performance on the energy efficiency in Korean petrochemical companies. The concept of the distance function is used to define the energy efficiency and the estimation of the distance function is performed using the stochastic frontier analysis. The inventory turnover is selected as the variable indicating the inventory management performance of the company. The main results of this study are as follows. First, the inventory turnover has a positive impact on energy efficiency. Second, during the period over 2011~2015, while the gap in energy efficiency among the companies expanded, the average energy efficiency decreased. Third, the average energy efficiency in upstream process companies was greater than downstream process companies and the gap in energy efficiency among downstream process companies was greater than upstream process companies. Fourth, the average marginal effect of inventory turnover on energy efficiency increased gradually from 2011 to 2015. Finally, the average marginal effect of inventory turnover in downstream process companies was greater than upstream process companies, and the gap in the marginal effect of inventory turnover among downstream process companies was greater than upstream process companies. These results together imply the importance of inventory management in terms of energy efficiency.

This study was prepared to present the research data for the promotion of Korean foods and restaurants in Korea and abroad by an analysis of the recognition and preference of Korean traditional foods and an importance-performance analysis of Korean restaurants by foreign visitors (n=351) and foreign residents (n=365). The most recognized Korean foods among foreigners were Bibimbap>Kimchi>Bulogi>Galbi>Samgyetang;however, the most preferred Korean foods were statistically different; Bibimbap>Kimchi>Bulgogi>Galbi>Rameyeon by foreign visitors and Bulgogi>Bibimbap>Galbi>Samgyetang>Kimchi by foreign residents. Especially, the preferences for Samgyetang and Dakgalbi were increased whereas that for Kimchi was decreased in foreign residents. The Korean foods were described as 'hot and pungent' and 'spicy' by foreign visitors, but 'hot and pungent', 'non-greasy' and 'salty' by foreign residents. In choosing a restaurant, 'quality of food' was most important among foreigners, but 'proper price' was considered more significant than 'sanitation and cleanness' by foreign residents compared with foreign visitors. The satisfaction with Korean restaurants of foreign residents was lower than that of foreign visitors. An analysis of importance and performance of Korean restaurants by foreigners was performed. There were significant differences in the evaluations of Korean restaurants between foreign visitors and foreign residents (p<0.05). The importance of the attributes related with 'foods' and 'sanitation' were rated higher by foreign residents. On the other hand, foreign visitors rated the importance of the attributes related to 'eating environment' and 'employees' more highly. Foreign residents significantly rated the performances of Korean restaurants lower in each attribute except 'additional free side dishes' and 'communications'.

The Korean construction industry has led the miraculous economic boost of Korea by providing solid domestic infrastructures such as highway, roads, and airports. It also played a critical role in global construction market and eaned more than 500 billions dollars in terms of their accumulated international orders. However, domestic construction market has significantly decreased in recent years due to the domestic political environments and global economic crisis. Therefore, the importance of international construction market cannot be more emphasized to the Korean construction market in order for the sustainable growth. There has been, however, little research in the area of identifying required competency elements for the Korean construction industry to stay successful in the global market. The main purpose of this study is to identify elements of core competency to increase global competitiveness for Korean construction industry. Core global construction competency elements were derived from the internal and external environmental analyses along with the extensive literature review, expert interviews and a survey. This study utilized the Importance-Performance Analysis (IPA) and a gap analysis in providing insights on the status competitiveness of the Korean construction industry in terms of required global core competency elements. The analysis shows that project management and financial management are the main areas for improvements required to engineering contractors while construction contractors need to take a more balanced approach among technical, project management, and financial management in order to increase their global competencies.

This study was aimed to identify surgical ward nurses' importance-performance awareness toward early mobilization after abdominal surgery patients. The date were collected from 162 nurses and the importance and performance of early mobilization were analyzed by the IPA method. The collected data were analyzed using the SPSS/WIN 25.0 by implementing descriptive statistics, independent t-test, paired t-test, and ANOVA. Early mobilization was divided into exercise of pulmonary complications and early ambulation. As a result of the study, the areas requiring concentration were 'check risk of aspiration', and areas requiring improvement were 'oral care', 'check lung sound', 'percussion/vibration', 'suction', and 'reinforcement exercise in bed'. Therefore, each item of early mobilization is recommended to reduce the gap between importance and performance in clinical care.

Purpose: The purpose of this study was to develop a tool that measures the quality of nursing service, to measure the quality of nursing service perceived by consumers, and to identify the gaps between ideal and actual nursing services. Method: A questionnaire was developed and distributed to 300 people who had been hospitalized in one of six general hospitals with quality of nursing services in five provincial cities in Korea. For data analysis, the SPSS/WIN(ver 10.0) program was used. Result: The 20 attributes included in the instrument of quality of nursing service is abstracted into 2 factors: tangibility and intangibility. In quality analysis, 15 of 20 attributes are minus scores, meaning that those nursing services are perceived as generally low. However among the minus scores' attributes, only two attributes are significant statistically. Gaps between importance and performance of the nursing service exists in 19 among 20 attributes. Conclusion: Nursing service quality (performance-expectation) needs to be improved, and Gaps (importance-performance) reduced. In addition, a tool measuring nursing service quality has to be developed so nurses can deal successfully with the quality and gaps of nursing service perceived by consumers.
