The purpose of this study is to examine the influence of terror information on fear of terror. This study examined how indirect delivery of terror information influence on the public's fear toward terror to identify the reason for fear toward terror and to analyze the varying influence based on the information type. Terror is an unjust way where individual or group with certain purpose use various types of violence such as murder, abduction, kidnapping, sniping, and plunder to raise social fear status and accomplish their own will. When terror occurs, many people show fear toward terror and they withdraw from all life activities due to fear. Thus, terror goes beyond creation of fear by using the violence. Instead, terror has a negative influence on people's lives in all social, economic, and cultural fields. This study examined how terror information influencing on indirect terror experience influences on the fear of terror. The result showed that both confirmed information and unconfirmed information influencing on indirect experience had significant influence on the fear of terror. Also, the result showed the unconfirmed terror information had higher influence on the fear compared to the confirmed information.

Although virtual reality technology may not be deemed as having a satisfactory quality for all users, it tends to incite interest because of the expectation that the technology can allow one to experience something that they may never experience in real life. The most important aspect of this indirect experience is the provision of immersive 3D audio and video, which interacts naturally with every action of the user. The immersive audio faithfully reproduces an acoustic scene in a space corresponding to the position and movement of the listener, and this technology is also called spatial audio. In this paper, we briefly introduce the trend of spatial audio technology in view of acquisition, analysis, reproduction, and the concept of MPEG-I audio standard technology, which is being promoted for spatial audio services.

From the digital perspective, customer journey and customer experience management are emerging as important issues for companies. While digital customer experience has become more important due to the recent surge in online sales of the home appliance products, customers' experience in online is not differentiated as offline-focused traditional methods are maintained. This study aims to analyze the characteristics and mutual influences of customer experiences at each stage of online purchase journey, and to explore the effects on the product repurchase intention, focusing on online purchasers of home appliance which are high-involvement products. As a result, both cognitive and affective experiences of the research phase directly affect satisfaction, whereas affective experience at the purchasing stage indicated indirect effects through cognitive experience. The experience of the research phase positively affects the next phase, the purchasing experience, and the experience of the purchasing phase leads to the intention to repurchase the product. However, it is also found that, depending on the choice of online channels, the experience of research phase may affect the product repurchase intention than the purchase experience.

With concerns for consumers' return behaviors affecting internet shopping malls' profits and product management in the internet clothing market, this study is designed to investigate determinants affecting return and path models for return behaviors. For an empirical study, questionnaires are prepared and respondents in their 20s and 30s with internet clothing purchase experience are selected using the convenience sampling. A total of 517 questionnaires are used for the final analysis. Data are analyzed by using SPSS 12.0 software and descriptive statistics, $x^2$-test, discriminant analysis, regression analysis, and path analysis is conducted. The results are as follows. First, ones who have returned after purchasing clothing items in internet shopping reached 63.4% of the total consumers. Respondents returned items with price at 50 thousand won or less stood at 67.2%, and the most frequent return shopping malls are open markets with their return rate at 51.1%. Second, variables such as risk perception, information search, impulse buying, buying experience, and age have a positive effect on return experience. Impulse buying and buying experience turn out to have a significant effect on the degree of return, but risk perception, information search, age, and gender to have an insignificant effect. Return intention is significantly affected by risk perception, gender, and age. Third, the analysis of path model for return experience shows that perceived risk has a positively effect, and information search has a direct effect as well as an indirect effect through buying experience or impulse buying. The analysis of path model for the degree of return shows that risk perception does not have effect, but information search has indirect effect through buying experience or impulse buying. This study is thought to find consumers' return behavior characteristics in online shopping, and help businesses operating online shopping malls to efficiently manage returns and set up strategies against returns.

With the development of information and communication technology, the demand for indirect experience contents using realistic media is increasing. It is important to keep the overall concept of the models consistently in order to immerse in the contents while watching realistic media. In the case of realistic media that provides an indirect experience of tourist attractions, modeling should be done by reflecting the actual information of the sites in order to provide an accurate experience. In this paper, we propose a three-dimensional modeling method of islands, representative tourism resources of the southern coast, by reflecting actual data. Since the proposed method is performed according to a structured procedure, it makes it easy to maintain the visual consistency of the entire model when several people work together. Implementation results show that the proposed method produces more realistic results than the modeling method using height information simply.

The learning control develops controllers that learn to improve their performance at executing a given task, based on experience performing this specific task. In a previous work, the authors presented an iterative precision of linear decentralized learning control based on p-integrated learning method for the vertical dynamic multiple systems. This paper develops an indirect decentralized learning control based on adaptive control method. The original motivation of the learning control field was learning in robots doing repetitive tasks such as an assembly line works. This paper starts with decentralized discrete time systems, and progresses to the robot application, modeling the robot as a time varying linear system in the neighborhood of the nominal trajectory, and using the usual robot controllers that are decentralized, treating each link as if it is independent of any coupling with other links. Some techniques will show up in the numerical simulation for vertical dynamic robot. The methods of learning system are shown for the iterative precision of each link.

The history of mankind has been at war with the war now going on in this moment. To prepare for this war, war history has been studied and its importance can be summarized in three main points. First, to understand the predictions of war and, second, to develop doctrines to fit changing circumstances, and to hone tactics through indirect war experiences. The curriculum of war history education for noncommissioned officer's department(two-year program) must include war lessons and skills to prepare the war. By indirect experiences through training they will have the ability to perform their duties in the field. This paper focuses to review the contents and methods of war history education which is being taught and to propose the new model for war history education for the students who are commissioned as officers after graduation.

We investigated the toxicity of zinc and aluminum hot-dip galvanized sheet steel to abalone Haliotis discus hannai via changes in the gill and hepatopancreas using histological and transmission electron microscopy analysis. Experimental groups were composed of one control and four exposure conditions (direct or indirect exposure to zinc and aluminum hot-dip galvanized sheet steel). In the control group, aluminum exposure groups (direct and indirect), and indirect zinc exposure group, abalone mortality was not observed until the end of the experiment, and no histopathological changes were observed in the gill and hepatopancreas. However, the direct zinc exposure group exhibited 100% mortality. Ultrastructural analysis of the cytoplasm of ciliated and microvilli-bearing epithelial cells from gill filaments revealed electron-dense vesicles near the cell membrane and disruption of the nuclear membrane. We also observed swollen mitochondria and a loss of mitochondrial cristae. The hepatopancreas showed similar changes, and we detected highly electron-dense particles within the vesicles. These results suggest that abalone exposed directly to zinc hot-dip galvanized sheet steel experience acute toxicity, causing damage to cell organelles in the gill and hepatopancreas and, finally, inducing mortality.

Objective: Studies confirming the lumber spine kinematics of direct or indirect segmental mobility under the application of joint mobilization, which induces passive force on the spine, are insufficient.Therefore, this study aims to obtain the underlying clinical data by identifying direct or indirect segmental mobility produced by Maitland's PA mobilization technique. Design: Randomized controlled trial design. Methods: Thirty subjects with no back pain participated in this study. X-ray testing equipment (SIG-40-525, Ecoray Inc., Korea) was used to verify the segmented movement of their lumbar. Joint mobilization was performed by physiotherapists with more than 10 years of experience in prescription therapy, and radiography was performed once without PA joint mobilization and once without the mobilization for comparing the lumbar vertebrae before and after the mobilization. The radiographs taken were analyzed using the picture archiving and communication system (PACS) program to measure the spinal displacement, intervertebral height, intervertebral angle, and lumbar lordosis angle. Results: Significant differences were observed in the lumbar displacement, intervertebral angle, and lumbar lordosis angle in all lumbar vertebrae before and after the mobilization. The intervertebral height indicated significant differences in all ventral vertebrae and only in L3-L4 and L4-L5 in dorsal vertebrae. Conclusions: This study suggests that the segmental mobility produced through indirect approaches plays an important role in inducing therapeutic effects in patients with back pain.
