Extant research has proposed that the Object-Spatial-Verbal cognitive style can elucidate individual differences in the preference for modality-specific information. However, no studies have yet ascertained whether this type of information processing evinces structural correlations in the brain. Therefore, the current study used voxel-based morphometry (VBM) analyses to investigate individual differences in gray matter volumes based on the Object-Spatial-Verbal cognitive style. For this purpose, ninety healthy young adults were recruited to participate in the study. They were administered the Korean version of the Object-Spatial-Verbal cognitive style questionnaire, and their anatomical brain images were scanned. The VBM results demonstrated that the participants' verbal scores were positively correlated with regional gray matter volumes (rGMVs) in the right superior temporal sulcus/superior temporal gyrus, the bilateral parahippocampal gyrus/fusiform gyrus, and the left inferior temporal gyrus. In addition, the rGMVs in these regions were negatively correlated with the relative spatial preference scores obtained by individual participants. The findings of the investigation provide anatomical evidence that the verbal cognitive style could be decidedly relevant to higher-level language processing, but not to basic language processing.

We have designed a 32-bit microprocessor with fixed point digital signal processing functionality. This processor, combines both general-purpose microprocessor and digital signal processor functionality using the reduced instruction set computer design principles. It has functional units for arithmetic operation, digital signal processing and memory access. They operate in parallel in order to remove stall cycles after DSP or load/store instructions, which usually need one or more issue latency cycles in addition to the first issue cycle. High performance was achieved with these parallel functional units while adopting a sophisticated five-stage pipeline stucture.

An experimental protocol was developed and tested in this study in order to quantify the motor control capability of the trunk movement for both healthy subjects and low-back pain (LBP) patients. Information processing capacity (bits/second) (Fitts, 1954) and dynamic motor perfor- mance such as flexion/extension velocity and acceleration were measured as motor control parameters under the controlled range of motion (ROM). In this study, the original experimental propocol (Kim et al., 1993, 1994) was re-designed to reduce the length of the test via a series of statistical analyses for clinical application. The accuracy of the shortened protocol was statistically examined and indicated no difference conpared to the original protocol in terms of evaluating information processing capacity. This protocol was also tested among ten healthy subjects and ten LBP patients for validation purpose. The results showed that the information processing capacity was not significantly diffenent between two groups due to the large variation although there was an apparent mean difference. Average movement time showed a significant increase in LBP patients com- pared to healthy subjects. In conclusion, it was found that the new short experimental protocol could quantify the motor control capability of neuromuscular system of the trunk and also showed the applicability to patient population.

The purpose of this study is to investigate the structural relationship between the viewing motivation, viewing commitment, re-audience intention, and game use intention of e-sports competition broadcast viewers. According to the purpose of the study, an online survey was conducted on 300 college students with experience watching broadcasting of e-sports competitions. After excluding inappropriate data from 8 out of 300 people, 292 people's data were used for final data processing. For data processing, the validity and reliability were verified using SPSS 26 and AMOS 23, and then the research hypothesis was verified. We has the results were shown as follows. First, it was found that entertainment, social intercourse and vicarious satisfaction had a positive effect on viewing commitment, but information has not significantly effect on viewing commitment. Second, it was found that viewing commitment had a positive effect on reviewing intention and game use intention. Third, it was found that reviewing intention had a positive effect on game use intention.

High quality camera images, with good contrast and intensity, are needed to obtain the desired information. Images need to be enhanced when they are dark or bright. The histogram equalization technique, which flattens the density distribution of an image, has been widely used to enhance image contrast due to its effectiveness and simplicity. This technique, however, cannot be used to enhance images that are either too dark or too bright. In addition, it is difficult to perform histogram equalization in real-time using a general-purpose computer. This paper proposes a histogram equalization technique with AGC (Automatic Gain Control) to extend the image enhancement range. It is designed using VHDL (VHSIC Hardware Description Language) to enhance images in real-time. The system is implemented with an FPGA (Field Programmable Gate Array). An image processing system with this FPGA is implemented. The performance of this image processing system is measured.

Purpose: This study uses the protection motivation theory and information processing theory to discuss the high number of fraud phenomenon in Indonesia which causes worries to the internet users. The second problem is the large amount of information transparency in e-commerce which actually hinders the users in making decisions so it causes a negative behavior pattern, namely discontinue usage intention. Design/methodology: Therefore, this research hopes to provide insight to the online or e-commerce business community, especially for Tokopedia, to develop its business from understanding the factors influencing consumer attitude when shopping online. The sample are students from Universitas Indonesia, Institut Teknologi Bandung, Institut Pertanian Bogor, Universitas Gadjah Mada and Institut Teknologi Surabaya, with total 900 respondents. Result: The results of this research indicate that ubiquitous connectivity (UC) variable significantly affects variables such as the privacy concern (PC), information transparency (IT) and information overload (IO). PC and IO variables also significantly affect Discontinue Usage Intention (DUI). Conclusion: This study gives a new perspective that despite the phenomenon, the millennial generation especially are not entirely concerned about the privacy concern, however, this study clearly shows that the privacy issue in the digital word continues to be something that needs to be cared for.

Purpose: The purpose of this study is to propose useful suggestions by analyzing the impact of SNS quality and the pressure which comes from SNS usage objectives on SNS discontinuance intention. Methods: We developed a SNS user's discontinuance intention model in terms of SNS quality and pressure of SNS usage. Survey data of SNS users was analyzed using multi-regression analysis for testing hypotheses. Results: We found that information quality plays an important role in lowering the SNS discontinuance intention. In addition, it was founded that pressure of social networking and information processing are positively related with the SNS discontinuance intention. Conclusion: We expect that this research can provide theoretical and practical implications. As for theoretical, this study can suggest the insight on conceptualization of SNS fatigue in the further study. Regarding practical implication, service providers can make their service strategies based on understanding our analysis.

Recently, much attention is paid on the office design be-cause the real world of work has undergone substantial changes, in both spatial and temporal aspects, due to the in-troduction of data processing technologies and new types of production. Today's renewed objectives of office are to define new physical space for work, to deal with economic and organizational changes. In the period of information, the purpose of an office is to improve the productivity for employers employees the comfort and vitality. Today's intellecture resources are necessary for the development in the modern business. The Hypid office, as an alternative in order to correspond the rapid changes, is proposed to give the space for satisfy-ing the basic desires of a human being-eating, resting and working. Accompanying with flexibility and comfortability, this office should include the space for personal purpose and the space for social purpose. Applying the concept of comfort like at home leads to re-lease a worker's stress from the society of information. The future office which is to enhance the quality of culture by in-tegrating indivisual, domestic and social life should commu-nicate efficiency, movement, energy, transformation.
