In this study, the factors affecting opportunism that causes conflict in the franchise system between franchisor and franchisee were analyzed based on the transaction cost theory and power-dependency theory. Hypothesis 1 states that franchisor support will negatively affect opportunism. Hypothesis 2 expresses that franchisee transaction-specific investment on the relationship with the franchisor will positively affect opportunism. Hypothesis 3 asserts that franchisee dependency on the franchisor will positively affect opportunism. All of these were supported. However, Hypothesis 4, maintaining that franchisee competitive intensity will positively affect opportunism, was not supported. The theoretical and practical implications of this study are as follows. This study has identified the antecedents of franchisor opportunism that causes conflict in the franchise system by comprehensively applying the transaction cost theory and power-dependency theory. This study can also identify what a company should manage specifically to lower opportunism by identifying the antecedents of franchisor opportunism in the franchise system. The limitations of this study and the directions for future studies are as follows. First, not all of the antecedents of franchisor opportunism in the franchise system have been extensively investigated from the transaction cost theory's and power-dependency theory's viewpoint. In the future, it is necessary to identify additional factors. Second, the study was conducted only from the franchisee's perspective. In future studies, more accurate research results can be obtained by simultaneously examining the franchisee's point of view and the franchisor's point of view.

Appearance is a means of competitiveness for modern people, and one of the factors that harms the desires of modern people is white hair. For the modern man who needs to express beautiful appearance to others by covering white moth, we performed hair analysis after white moth hair dye treatment. The maximum modulus and tangential modulus according to the maximum load, maximum tensile strength, maximum elongation, breaking load, fracture strength, elongation at break, and evaluation interval between 1N-3N experimental group and control group of 1N-Respectively. Maximum load, maximum tensile strength, breaking load and breaking strength tended to be larger than those of the control group, while the maximum elongation and breaking elongation were the highest in the control group and the elongation decreased with the experimental group treatment. The maximum modulus and tangential modulus of the 1N-3N test group were higher than those of the control group at 0~0.15 and 0.15~2.5, respectively. Based on the study on the cosmetic changes of the hair before and after the treatment, it can be used as a basic data to select the correct oxidative hair dye product, the proper amount of application and the time to leave.

Technology cooperation is a necessary factor for small and medium sized firms to be survived and developed because small and medium sized firms can make economy scale and economy scope by new advanced technologies obtained from technology cooperation. Therefore, the technology cooperation of small and medium sized firms can be thought as their specific resource. Due to the importance of technology cooperation, many previous studies paid an attention on its positive effect. Unlike the related studies, this study examined the link among uncertainty of technology environment, relationship characteristics(such as degree of technology cooperation and influential strategy), and relationship tie. The empirical results are reported as follows: Firstly, uncertainty of technology environment positively affected on degree of technology cooperation. Secondly, degree of technology cooperation positively affected on uncoercive influential strategies of both own firm and partner firm. Thirdly, degree of technology cooperation and uncoercive influential strategy of own firm have positive effects on relationship tie while uncoercive influential strategy of partner firm does not. The positive effect of uncoercive influential strategy of own firm means the importance of strategic countermeasures to promote relationship tie in technology cooperation of both own firm and partner firm.

In this study, offshore modular pier system using the ultra-high performance concrete was developed for the offshore construction environment. For the application of offshore modular pier system, the design, fabrication, and construction performance evaluation were performed using ultra-high performance concrete a compressive strength 120 MPa or more and a direct tensile strength 7 MPa or more. For offshore piers previously constructed with precast concrete, it was intended to verify the idea and possibility of solving errors due to position or vertical deformation during the driving of the foundation pile part during the construction stage. Furthermore, a offshore modular pier system was fabricated with ultra-high performance concrete for the construction performance evaluation. The results showed that a offshore modular pier system secured about 9 % of sectional performance of load bearing capacity under ultimate load conditions. If the offshore modular pier system developed through this study is utilized in the future, it is judged that competitiveness due to sufficient durability and constructability can be secured.

The objectives of this study were to determine the effects of thinning intensity on the changes of vegetation structure in Japanese Evergreen Oak(Quercus acuta Thunb.) stands in Wando-arboretum. The flora were composed of 24 families, 33 genera, and 36species in thinned sites. The dominant layer of control site showed higher number of plant species than that of treatment sites. On the while, the sub-dominant layer, shrub layer, and herbaceous layer treatment sites showed higher number of plant species than control site. According to the analysis of importance value, Q. acuta in the dominant layer, Q. acuta and Camellia japonica in sub-dominant layer, and Camellia japonica in shrub layer showed the highest importance values, respectively. The importance value of Trachelospermum asiaticum was the highest in the herbaceous layer. According to the results, species diversity was higher in descending order of heavy thinning, light thinning, and control. This result could be explained by increased light transmissions from higher thinning intensity than in other treatments. In this context, the results of this study may be useful for selecting appropriate tending methods in terms of forest management and biodiversity conservation.

Reinforced open cell micro structured foams were prepared by the polymerization of high internal phase emulsions incorporating inorganic thickeners. Organoclays were used as oil phase thickener, and sodium montmorillonite was used as aqueous phase thickener. Rheological properties of emulsions increased as oil phase thickener concentration and agitation speed increased, due to the reduced drop size reflecting both competition between continuous and dispersed phase viscosities and increase of shear force. Drop size variation with thickener concentration could be explained by a dimensional analysis between capillary number and viscosity ratio. Upon the foams polymerized by the emulsions, compression properties, such as crush strength and Young's modulus were measured and compared. Among the microcellular foams, the foam incorporated with an organoclay having reactive group showed outstanding properties. It is speculated that the exfoliated silicate layers inside polystyrene matrix, resulting in nanocomposite foam, are the main reason why this foam has enhanced properties.
