The target echoes contain information on the target such as the orientation, kinematics, and internal structure, as well as the external geometrical shape of the target. In addition, the pattern of the target echoes depends on the arrangement of the transmitters and receivers in space. Therefore, the study of the target echoes in a multi-static SONAR system can be useful for detecting and tracking submerged objects using an underwater surveillance system. For this purpose, an acoustic measuring system for multi-static target echoes was designed and tested in an acoustic water tank. Some preliminary data are presented and discussed.

A cooperating control algorithm for two nonholonomic mobile robots is proposed. The task is composed of collision avoidance against obstacles and carrying a ladder. The front robot and the rear robot are called the leader and the follower, respectively. Each robot has a nonholonomic constraint so it cannot move in perpendicular directions. The environment is initially supposed to be unknown except target position. The torque that drives leader is determined by distance between the leader and the target position or the distance between it and the obstacles. The torque by target is attractive and the torque by obstacles is repulsive. The two mobile robots are supposed to be connected by link that can be expanded and contracted. The follower computes its torque using position and orientation information from the leader by communication. Simulation results show that the robots can drive to target position without colliding into the obstacles and maintain the distance in the allowable range.

Silver doped ZnO (SZO) films were prepared by rf magnetron sputtering on glass substrates with extraordinary designed ZnO target. With the doping source for target, use AgNO$_3$ powder on a various rate (0, 2, and 4 wt.%). We investigated dependence of coating parameter such as dopant content in target and substrate temperature in the SZO films. The SZO films have a preferred orientation in the (002) direction. As amounts of the Ag dopant in the target were increased, the crystallinity and the transmittance and optical band gap were decreased. And the substrate temperature were increased, the crystallinity and the transmittance were increased. But the crystallinity and the transmittance of SZO films were retrograde at 200$^{\circ}C$. Upside facts were related with composition. In addition, the Oxygen K-edge features of the SZO films were investigated by using near edge X-ray absorption fine structure (NEXAFS) spectroscopy. Changes of optical band gap of the SZO films were explained compared with XRD, XPS and NEXAFS spectra.

The purpose of this study is examine the factors influencing performance of long-term orientation and Corporate Social Responsibility(CSR) activities. This model tests various theoretical research hypotheses relating to social enterprise, CSR activities and long-term orientation. The proposed model is analyzed to target 115 social entrepreneurs with Smart Partial Least Square(PLS) 2.0. The result of hypothesis testing are as follows. First, long-term orientation positively influence community responsibility, environmental responsibility, and product(service) responsibility. Second, community responsibility positively influence financial and non-financial performance. Third, environmental responsibility positively influence non-financial performance, but does not significantly influence financial performance. Finally, product(service) responsibility does not significantly influence financial and non-financial performance. The results of this study will provide various implications to improve performance, long-term orientation, and CSR activities in social enterprise.

This paper reports the structural and optical properties of ZnO/glass thin films grown by radio-frequency magnetron sputtering with a powder target. In contrast to ZnO ceramic target typically used, a ZnO raw powder target was sputtered in this study. ZnO grew with the (0002) preferred orientation along the surface normal direction. Initially, the surface of ZnO thin films was flat considerably and then it became rougher as the thickness increased. The optical transmittance was as high as 88% in the range of 400-1000 nm. The bandgap energy of 3.23 eV at the 220 nm thick sample was estimated.

The automation of final inspection and tuning process in the manufacturing of electric products is hot issue now, because it is the only part that has not been wholey automized yet, mainly due to the difficulties to handle so small size of VR which is the final tuning point in the most of electric products. For the automation of this process, at first the accurate measurement of position and orientation of SMD VR on PCB in real time is strongly needed. In this paper, a new image processing algorithm to detect the center position and orientation of target VR by using machine vision is proposed for automatic final tuning of the 8mm camcoder's performance. In the method, the outline feature of object is used actively. The usefulness of the proposed methods were tested by several experiments, and the results showed enough accuracy for both of position and orientation. Additatively, we discussed about the total visual system construction and preprocessing of image.

The purpose of this study was to examine consumers' behaviors toward ready-to-eat foods and to develop ready-to-eat food market segmentation in Korea. The food-related lifestyle and purchase behaviors of ready-to-eat foods were evaluated using 410 ready-to-eat food consumers in the Republic of Korea. Four factors were extracted by exploratory factor analysis (health-orientation, taste-orientation, convenience-orientation, and tradition-orientation) to explain the ready-to eat food consumers' food-related lifestyles. The results of cluster analysis indicated that "tradition seekers" and "convenience seekers" should be regarded as the target segments. Chi-square tests and t-tests of the subdivided groups showed there were significant differences across marital status, education level, family type, eating-out expenditure, place of purchase, and reason for purchase. In conclusion, the tradition seekers consumed more ready-to-eat foods from discount marts or specialty stores and ate them between meals more often than the convenience seekers. In contrast, the convenience seekers purchased more ready-to-eat foods at convenience stores and ate them as meals more often than the tradition seekers. These findings suggest that ready-to-eat food market segmentation based on food-related lifestyles can be applied to develop proper marketing strategies.

Variables such as R&D capability and organizational orientation have been dealt with in previous studies on factors that affect the success of new products/services in technology-based companies, but there have been few studies examining the causal relationship of these variables from an integrated perspective. Therefore, this study aims to analyze the effect of the organizational orientation and R&D capability of technology-based SMEs, consisting of customer orientation, innovation orientation, and competitor orientation, on the success of new products/services. In addition, we want to analyze the influence of a company's product/service competitiveness on the success of new products/services. The survey was commissioned by a research company, and 382 valid copies were analyzed by conducting a survey to corporate members in the technical job-related industry. The questionnaire analysis was performed using SPSS 26.0 and Smart PLS 3.0.Customer orientation, innovation orientation, and competitor orientation were found to have a positive effect on product/service competitiveness. It can be said that market changes in product/service competitiveness, technology improvement capability, target market analysis, etc. meet the objectives of most research projects, such as the success of new products/services. In addition, product/service competitiveness was found to have a positive effect on the success of new products/services. It can be seen that R&D capability has a positive effect on the success of new products/services and plays an important role in business expansion of SMEs. From this analysis result, it was found that the organizational orientation and R&D capability of a company have a positive effect on the success of new products/services. Based on the results of this study, implications were presented on the factors that a company must have for the success of new products/services.
