Buckling Restrained Braced (BRB) frames have been widely used as an efficient seismic load resisting system in recent years mostly due to their symmetric and stable hysteretic behavior and significant energy dissipation capacity. In this study, to provide a better understanding of the behavior of BRB frames with various beam-column connections, a numerical study using non-linear finite element (FE) analysis is conducted. All models are implemented in the Abaqus software package following an explicit formulation. Initially, the results of the FE model are verified with experimental data. Then, diverse beam-column connections are modeled for the sake of comparison from the shear capacity, energy dissipation and frame hysteresis behavior points of view until appropriate performance is assessed. The considered connections are divided into three different categories: (1) simple beam-column connections including connection by web angle and connection by seat angle; (2) semi-rigid connection including connection by web and seat angles; and (3) rigid beam-column connections by upper-lower beam plates and beam connections with web and flange splices. Results of the non-linear FE analyses show that these types of beam-column connections have little effect on the maximum story drift and shear capacity of BRB frames. However, the connection type has a significant effect on the amount of energy dissipation and hysteresis behavior of BRB frames. Also, changes in length and thickness of the angles in simple and semi-rigid connections and changes in length and thickness of plates in rigid connections have slight effects (less than 4%) on the overall frame behavior.

In this paper,the existence between the difference of the organization culture and th organizational performance is studied. Many previous studies verified the relationship between the two. The Korean Company survey is based on Rousseau's orgnization culture style,and is analyzed using the statistical package. Rousseau's culture style is composed of three components :consturctive style, passive/defensive style,and aggressive/defensive style. The characteristics of each orgnizational analusis are examined. The elements of the constructive style represent positive values on attitude varriables which are selected as the organizational performence variables. The elements of the passive/defensive style represent neagtive values of the attitude variables. Thus,they have an inverse relationship with this culture style. However,the aggressive/ defensive culture's results represent the weak positive relationship compared with the passive/defensive style. For the improvement of the organizational performance,the orgnzational culture has to develop the constructive style and it is better to minimize the defensive style.

This study intends to offer suggestions for improving the security and competitive power of traditional liquors by investing in the status of intellectual property rights. Merchandising and the marketing strategies of traditional liquor are also addressed. The data was collected through a questionnaire survey given to 101 CEOs of traditional liquor manufacturers. The major results of this study were as follows: The management types of traditional liquor manufacturers were classified as the company 57 (56.4%), the corporation or the union 29 (28.7%), domestic industry 10 (9.9%), and marketing community or technology center 5 (5.0%). The competitive power degree of traditional liquor products was classified as strength 30 (31.6%), usual 30 (31.6%), weakness 35 (36.8%). The elements of strong competitive power were taste, functional (wellbeing) character, and attractiveness of the brand name. On the other side, reasons for weakness in competitive power were the marketing system, price competitiveness, and advertisement. The trademark registration of the traditional liquor appeared with 53%. The reasons not to pursue a trademark registration included the complicated and unnecessary process of registration acquisition, high registration expenses, etc. The perceptions of CEOs about the consumer's brand awareness for their product were low with an average 2.97. Explanations included insufficient advertisement and public relations, unrefined trademark design, and the meaninglessness of brand names. The marketing strategy of traditional liquor manufacturers according to annual sales were as follows: Manufacturers with high sales emphasized marketing strategies that focused on functional character, traditional image, high quality in image and package materials and design, high price strategies based on quality, and various sale promotions.

This study surveys the state of 'children's snacks' sold within the Green Food Zone and that of High Calorie Foods with Low Nutrition Value (HCFLNV). The main purposes are the analyses of foods in accordance to KFDA Program for HCFLNV and an analysis of differences in HCFLNV that are dependent on relevant factors such as food types, school types, origins, the scale of manufacturing company, area and price. Based on the analyses, educational and political implications have been sought that will form nutritious dietary habits, contribute to the prevention of obesity, and improve health in child consumers. The methodologies of this study are literature studies and surveys. The results of this study can be summarized as following. First, the number of children's snacks is 517 items of total 645 gathered within 150 Green Food Zones. Candies are the most popular item, next are cookies, chocolates, and breads. Second, in the real state survey there are 186 HCFLNV (36.0%) among children's snacks sold within Green Food Zone. Based on the survey results, the marking of HCFLNV on the package of children's snacks and the extension of the ban of HCFLNV sales to all stores within the Green Food Zone are strongly suggested. This provides preliminary data related to children's snacks and food safety. With enforcement of the Special Act on the Safety Management of Children's Dietary Life, the rate of HCFLNV has decreased and the child snack product environment in stores has improved. However, it is necessary to supervise low-priced snacks and promote an awareness of HCFLNV along with the child consumer education of food safety is needed.

Quite a demanding task frequently arises in space engineering, when dealing with the cargo accommodation of modules and vehicles. The objective of this effort usually aims at maximizing the loaded cargo, or, at least, at meeting the logistic requirements posed by the space agencies. Complex accommodation rules are supposed to be taken into account, in compliance with strict balancing conditions and very tight operational restrictions. The context of the International Space Station (ISS) has paved the way for a relevant research and development activity, providing the company with a remarkable expertise in the field. CAST (Cargo Accommodation Support Tool) is a dedicated in-house software package (funded by the European Space Agency, ESA, and achieved by Thales Alenia Space), to carry out the whole loading of the Automated Transfer Vehicle (ATV). An ad hoc version, tailored to the Columbus (ISS attached laboratory) on-board stowage issue, has been further implemented and is to be used from now on. This article surveys the overall approach followed, highlighting the advantages of the methodology put forward, both in terms of solution quality and time saving, through an overview of the outcomes obtained to date. Insights on possible extensions to further space applications, especially in the perspective of the paramount challenges of the near future, are, in addition, presented.
