The relationship-orientation is an important concept for understanding both of marketing theory and practice. However, not many research have focused on how to develop the relationship-orientation of end users. Therefore, the objective of this research is to confirm the key factors relevant to the relationship-orientation. This research studies(1) the transaction style of individuals, and (2) social influences on the relationship-orientation. Customers want to reduce the number of choice sets because of transaction style, including (1) efficiency of decision making, (2) simplification of information processing, (3) avoidance of future perceived risk, and (4) pursuit of cognitive consistency. Customers are influenced by social factors such as family members, reference groups, and opinion leaders. The following conclusions were drawn based on results of research analysis: (1) efficiency of decision making and avoidance of future perceived risk affect the relationship-orientation, and (2) influences of family members and opinion leaders to the focal relationship affect the relationship-orientation of individuals.

The main purpose of this paper is to Investigate the free vibrations of circular curved members resting on nonhomogeneous elastic foundations. The governing differential equations derived in a previous paper are used. The governing equations are solved numerically to obtain frequencies. Hinged-hinged end constraint is considered in numerical examples. The lowest three natural frequencies are calculated over a wide range of non-dimensional system parameters: the foundation rested ratio, the foundation parameter, the horizontal rise to span length ratio, the slenderness ratio, and the width ratio of the contact area between the member and the foundation.

Front impacted SUV vehicle shows that the front parts of side members are collapsed by the bending due to the transverse load exerted at the end of side members. Side member models were impacted with various angles in order to study the crash performance according to the impact angle. Even for the small impact angle of $10^{\circ}$, crash performance seriously deteriorated and the deformations for impact angle $15^{\circ}$ were similar to those from the front body impact analysis. In addition, the angled front impact analysis for the straight member with hat section was carried out and the effects of inner reinforcement shape on crash performance was investigated.

This paper presents a decentralized coordination for a small-scale mobile robot teams performing a task through cooperation. Robot teams are required to generate and maintain various geometric patterns adapting to an environment and/or a task in many cooperative applications. In particular, all robots must continue to strive toward achieving the team's mission even if some members fail to perform their role. Toward this end, given the number of robots in a team, an effective coordination is investigated for decentralized formation control strategies. Specifically, all members are required first to reach agreement on their coordinate system and have an identifier (ID) for role assignment in a self-organizing way. Then, employing IDs on individual robots within a common coordinate system, a decentralized neighbor-referenced formation control is realized to generate, keep, and switch between different geometric shapes. This approach is verified using an in-house simulator and physical mobile robots. We detail and evaluate the formation control approach, whose common features include self-organization, robustness, and flexibility.

The design of truss type sign support structures is based on the guidelines provided by the American Association of State Highway and Transportation Officials Standard Specifications for Highway Signs, Luminaries and Traffic Signals and the American Institute of Steel Construction Design Specifications. Using these specifications, the column design strength is normally determined using the effective length approach. This approach does not always accurately address all issues associated with frame stability, including the actual end conditions of the individual members, variations of the loads in the members, and the resulting sidesway buckling for truss type sign support structures. This paper provides insight into the problems with the simplified design approach for determining the effective lengths and discusses different approaches for overcoming these simplifications. A system buckling approach, also known as a rational buckling analysis, is used in this study to determine improved predictions for design strength of truss type sign support structures.

This thesis mainly deals with what is th Gurodae, recorded of the YeonggeonUigwe and the SanleungUigwe. Gurodae makes diverse appearance In Uigwes.(久老代, 仇老代, 求路代, 仇老臺, 仇露臺, 求露臺, 仇累臺, 九累臺) It seems that Gurdae was an architectural member used on the roof. Especially that was a member of the eaves. Gurodae looks like a Pyeonggodae, located on the end of the rafters. But it differs in the shape compare to that of Pyeonggodae, Gurodae has the shape of combined members, Pyeonggoaed and Chakgo. Chakgo is a member covering the spae, between two Buyeons So Gurodae has the shape of prominence and depression. The result obtained by surveying the Uigwes is the Gurodae is the Gurodae used until 1789. After the publication of HyeonlyungwonUigwe in 1789, that member was no longer existed on the other Uigwes. In 1794, the making Hwaseong fortress, Gurodae divieed into two members, Chopyeonggodae and Chakgo. Since then Chopyeonggodae and Chakgo never combined again.

This study investigated possible ways to replace conventional stirrups used on high-strength concrete members with improved reinforcing materials. Headed bar and high-strength steel were chosen to substitute for conventional stirrups, and an experimental comparison between the shear behavior of high-strength concrete large beams reinforced with conventional stirrups and the chosen stirrup substitutes was made. Test results indicated that the headed bar and the high-strength steel led to a significant reserve of shear strength and a good redistribution of shear between stirrups after shear cracking. This is due to the headed bar providing excellent end anchorage and the high-strength steel successfully resisting higher and sudden shear transmission from the concrete to the shear reinforcement. Experimental results presented in this paper were also compared with various prediction models for shear strength of concrete members.

The study investigated the effects of differences in some electronic course designs on university students' Computational Thinking Skills (CTS). Towards this end, the researcher adopted the experimental research design of a quasi-experimental of two experimental groups. The first group was taught an e-course designed in a sequential pattern, and the other group's course was designed according to the holistic model. A CTSs test was prepared to collect the relevant data, and the data were analyzed statistically using these tests- Pearson correlation Mann Whitney and Alpha Cronbach. Results revealed statistically-significant differences at the level α=0.05 between the mean scores of the first and second experimental groups in favor of the latter in the CTS test. The findings gave ground to put forward some salient recommendations, including the need to expand computational thinking in universities' educational process. It also recommends urging faculty members to enhance e-courses in the educational process and provide technical support to students and faculty members.

This study aims at developing a torsional strength model based on a nonlinear analysis method presented in the previous studies. To this end, flexural neutral axis depth of a reinforced concrete section and effective thickness of an idealized thin-walled tube were formulated based on reasonable approximations. In addition, various sectional force components, such as shear, flexure, axial compression, and torsional moment, were considered in estimating torsional strength by addressing a simple and linear strain profile. Existing test results were collected from literature for verifications by comparing with those estimated from the proposed model. On this basis, it can be confirmed that the proposed model can evaluate the torsional strength of RC members subjected to combined loads with a good level of accuracy, and it also well captured inter-related mechanisms between shear, bending moment, axial compression, and torsion.

Recently, security behavior of members of organizations has been recognized as a critical part of information security at the corporate level. Leakage of customers' information brings more attention to information security behavior of organizations and the importance of a task force. Research on information breach and information security is actively conducted of personal behavior toward security threats or members of organizations who use security technology. This study aims to identify factors of influence on information security behavior of members of organizations and to empirically find out how these factors affect information security behavior through behavior toward attitude, subjective norm and perceived behavior control. On the basis of the research, this study will present effective and efficient ways to foster information security activities of members of organizations. To this end, the study presented a research model that applied significant variables based on integration of Theory of Planned Behavior (TPB) and Theory of Protection Motivation (TPM). To empirically verify this research model, the study conducted a survey of members of organizations who had security-related work experience at companies. So, it is critical for members of organizations to encourage positive word of mouth (WOM) about information security behavior. Results show that based on the integration of TPM and TPB, perceived vulnerability, perceived severity, perceived efficiency and perceived barriers of information security behavior of members of organizations had significant influences on mediating variables such as behavior toward attitude, subjective norm, perceived behavior control and intention. They also had significant influences on organization information security behavior which is a dependent variable. This study indicates companies should introduce various security solutions so that members of the organizations can prevent and respond to potential internal and external security risks. In addition, they will have to take actions to inspect vulnerability of information system and to meet security requirements such as security patches.
