This study aims to identify a new direction in the consumer-brand relationship by quantitatively approaching from the psychological aspect consumers' brand love, which is the most powerful strategic element in forming an emotional consumer-brand relationship. What significance does brand love have in a consumer-brand relationship? Brand love is the most fundamental in the emotional consumer-brand relationship. Through brand ownership, consumers add meaning to their lives, and love brands by expressing themselves. Love is a scale that understands consumer-brand relationship from the most interpersonal aspect and can be considered as the most essential element in an empathetic relationship. Consumers' brand love not only determines brand image and reliability but through brand loyalty, it also influences market competitiveness. In addition, as a medium that can overcome brand crisis, it serves as a turning point of the relationship and can enhance the strength of consumers' brand love. Under such generational and theoretical background, this study took a psychological approach on love in emotional consumer-brand relationship. Focusing on the most representative theory and classification of love, Sternberg's Triangular Theory of Love, types of brand love were examined. 552 questionnaires were distributed through a survey with mobile phone service and product brands, and a factor analysis was conducted. Types of brand love revealed through the results of this study were very similar to Sternberg's types of love, and it was found that the types of brand love varied based on product category. It can be suggested that the concept of brand love is an important strategic idea in brand communication.

In order to use a recycled aggregate concrete for precast concrete box structures, the structural behaviors should be analytically and experimentally evaluated. In this study, full-scale precast concrete box structures are manufactured using the recycled aggregate (30% replacement) and natural aggregate. Then, the flexural failure test and shear failure test as well as water leakage lest for the structures arc carried out. First of all, test results of compressive strength show that recycled aggregate concrete is only 4% lower than normal concrete. In the flexural and shear failure test, the structural performances of precast box using the recycled aggregate concrete are 95% of the capacities of normal precast concrete box or more. Especially, the water leakage test shows that leakage pressure of recycled concrete box is more than the critical value, 60kPa, as well as 9% higher than normal precast concrete box. These test results are analyzed and compared with results of finite clement analysis. The comparison shows that test results are more excellent than analytical results. Also, the comparison confirms the applicability of recycled aggregate concrete for the use as practical precast concrete box structure.

It has been reported that certain ingredients added to cosmetics clog the skin pores and this can cause outbreaks of comedones which are the primary sign of acne leading to inflammatory acne. This research aims to establish objective evaluation criteria for non-comedogenic cosmetics suitable for acne prone skin. The research has been carried out to examine non-comedogenic test performed in foreign clinical institutions and to establish the evaluation method for detecting comedones outbreaks through repetitive closed back-patch test, Also, usability evaluation on face skin is performed additionally to the same subjects. The analysis of the comedones collected through repetitive closed back-patch test confirmed that the test products, moisturizer and sunscreen product, did not cause comedones. These results had no correlation with the analysis result of the comedones collected from face skin or visual evaluation of acne by Global Acne Grading System (GAGS) in face usability test. Additionally, Oil red O staining was performed on the collected comedones specimen for easy distinction of comedones from hair follicle in image analysis. The analysis result of stained specimen showed higher precision than that of non-stained specimen. This study established a new version of non-comedogenic test for cosmetics, whose objectivity and reliability were improved by inclusion of comedones staining step.

This study conducted a survey on 319 Chinese women in their 20s to 50s living in three large cities in China, with an aim to analyze the influence on the purchasing behavior and satisfaction for Korean cosmetics depending on their complex purchasing tendencies. According to the research, the rational tendency was higher when the subjects were over 40 years old and married, and the impulsive tendency was the highest in those in their 30s. There was no huge difference in regions depending on the two tendencies, while there were statistically significant differences in purchasing period, times and costs when buying cosmetics. In addition, purchasing satisfaction for cosmetics had a positive correlation with purchasing tendencies. The subjects pursued convenience in purchasing as their rational tendency was higher, while they sought the trends as their impulsive tendency was higher. Based on the results, it is expected to maximize purchasing satisfaction of Chinese female consumers depending on their purchasing tendencies, if the Korean cosmetics makers provide reliable quality assurance, product exchange and customer management services. It is also expected to help revitalize the beauty market for China as well as Southeast Asia, if the Korean cosmetics companies implement differentiated marketing strategies targeting the customers in the age group with the impulsive consumption tendency.

As most companies in the world are much interested in the overseas market as well as in the domestic market, many Korean food service enterprises came to focus on extending their branches to the overseas market. However, lack of business strategies including market research, marketing strategies, localization, etc. has made them continue to fail in market entry. The purpose of this study is to develop entry mode of determinants of Korean food service enterprises, considering their characteristic factors and environment factors in the overseas market. To do this, companies which have a head quarter in Korea and over 2 year business experience in the overseas market were chosen and used for a self-administered questionnaire survey. Statistical processing, including descriptive statistics, logistic regressing analysis, and multi regression analysis using an SPSS/PC 12.0 statistical package were conducted The result is as follows. First, explanation suitability was 85% of the entry mode in the overseas market. Second, as business size was smaller, product differentiation was higher, and CEO's will for success in the overseas market was higher, independent entry mode in the overseas market was likely to he chosen. Lastly, as the uncertainty of demand and trade barrier were lower, and a sociocultural gap was smaller, independent entry mode in the overseas market was likely to be chosen.

In general, Personal Navigation Systems (PNSs) can be defined systems to acquire pedestrian positional information. GPS is an example of PNS. However, GPS can only be used where the GPS signal can be received. Pedestrian Dead Reckoning (PDR) can estimate the positional information of pedestrians using Inertial Measurement Unit (IMU). Therefore, PDR can be used for GPS-disabled areas. This paper proposes a PDR scheme considering various movement types over GPS-disabled areas as combat environments. We propose a movement distance estimation scheme and movement direction estimation scheme as pedestrian's various movement types such as walking, running and crawling using IMU. Also, we propose a fusion algorithm between GPS and PDR to mitigate the lack of accuracy of positional information at the entrance to the building. The proposed algorithm has been tested in a real test bed. In the experimental results, the proposed algorithms exhibited an average position error distance of 5.64m and position error rate in goal point of 3.41% as a pedestrian traveled 0.6km.

Domestic hydraulic drifters till now have been developed by benchmarking products from overseas leading companies. However, they do not have excellent impact performance as they are not suitable for characteristics (large flow rate and low pressure) of Korean hydraulic drill power pack, and therefore, research on the optimum design has not made much headway. This study performs multi-objective function optimization for hydraulic drifters whose capacity has been redesigned to deal with the large flow rate, and also with the help of this function, it aims to improve impact power and reduce supply and surge pressure. A summary of the research study is as follows: First, we set goals for improving impact power, supply pressure, and surge pressure, and then perform multi-objective function optimization on them. After that, we secure the reliability of the optimized analytical model by comparing the test results of the prototype built by the optimized design with the analysis results of the analytical model. This study used SimulationX, that is the hydraulic system analysis software, and EasyDesign, which is a multi-objective function optimization program. Through this research, we have achieved the results that satisfy the goal of developing high power drifters suitable for Korean type hydraulic drills.

Recently, standardization of installation progress and technology of site acceptance test(SAT) for energy storage system(ESS) are being required due to performance of ESS depending on working condition and environment even though the quality and safety of each component of ESS　is guaranteed. And also, it has been required to perform not only performance testing by H/W equipments but also performance verification by S/W tool, in order to more accurately and reliably validate the performance of the ESS in advanced countries. Therefore, this paper proposes evaluation algorithm for SAT to evaluate performance of ESS and presents modeling of SAT test equipment for ESS by using PSCAD/EMTDC. Furthermore, 30[kW] scaled portable test equipments is implemented based on the proposed algorithm and modeling. From the various simulation and test results, it is confirmed that performance of ESS related to characteristics of capacity and Round-trip efficiency, Duty-cycle efficiency, low voltage ride through(LVRT) and Anti-islanding can be accurately evaluated and that the simulation results of PSCAD/EMTDC are identical to test results of 30[kW] test equipment.

When the fouling of a vessel occurs, its resistance at sea increases and there is a corresponding increase in fuel consumption. The maintenance cost of the vessel also increases because it is time-consuming to remove the fouling. To solve this problem and minimize environmental contamination of sea-water, there have been recent developments in anti-fouling paints as self-polishing copolymers that not include toxic elements such as tin. When these conventional techniques are applied to vessels, polishing is promoted during the operation whereby friction or vibration with seawater occurs. This leads to enhanced anti-fouling performance. However, when fouling is intensified such as during an anchorage, there is no flow of seawater and polishing is suppressed. This leads to a deterioration of the performance of anti-fouling. To solve these problems, we developed a system that induces vibration in a vessel during anchorage. As such, the deterioration of polishing due to insuf icient flow of seawater is inhibited. The reliability of the ultrasonic antifouling system was evaluated by calculating its repeatability. The removal efficiency of fouling of the proposed system was qualitatively evaluated using test specimens. The test revealed that the value of the coefficient of variation for the reproducibility of the frequency and amplitude was 0.2 % and 4.0 % on average. The degree of fouling of the specimens was the highest at 73.3 g in the No.5 sepcimen. Moreover, efficiency of fouling removal was 93.2 % on average compared to the specimens without the proposed system.
