Individual adoption and sustained usage of information technology(IT) are crucial prerequisites for exploiting IT as integral components of organizational work. Previous studies on technology adoption in workplace suggest that acceptance behavior is influenced by a variety of factors such as individual differences, social influences, beliefs, attitudes, and situational influences. In this paper, we introduce a research model to predict the usage behavior of intranet in workplace and also explain the causal relationships among variables. Based on the survey of 333 intranet users, this study uses structural equation model with LISREL 8.12. This study suggests several major results from surveys and analysis from them. Perceived use is influenced by intranet experience, task equivocality, organizational support, and perceived ease of use, Experience and organizational support determine perceived ease of use. Task equivocality, task interdependence, and organizational support have positive effects on subjective norm. On the other hand, present usage, which is a dependent variable in this model, is influenced by perceived use, experience, task interdependence, and organizational support.

The smart phone is a representative personal device that can provide information onan individual's behavior related to real-life places, where the mobile phone users frequently stay and go, and the people who call or meet with the user. This paper proposes moving modeling that is based on the individual life logs using mobile phone data for identifying individuals. This method can be used to recommend the most suitable phone-service.

The compressive and torsional buckling behavior of carbon nanotube bundles at room temperature is examined with classical molecular dynamics simulation. The critical compressive load and stiffness of a single carbon nanotube in the bundle are found to be similar to those of individual carbon nanotubes. However, the critical torsional moment and stiffness of a single carbon nanotube in the bundle are found to be higher than those of individual carbon nanotubes. In addition, this study demonstrates that van der Waals interactions between the nanotubes in the bundle significantly affect the critical compressive load of the nanotube bundle.

This study was performed to compare the individual characteristics of the vocalization and behavior in the adult female German Shepherd in military service. In this study, a stranger and an other strange dog approached their kennel. Their body postures included ears forward and up, slowly wagged tails, lips raised, mouth open and teeth exposed. It was Interesting that their vocalizations were only the bark without any combination of other vocalizations. There were significant differences between duration of call(DC), pitch(P), Fl formant, F2 formant, F3 formant and F4 formant(p<0.05) except interval between call(IBC) and intensity(I) among their barks. It was suggested that the differences between same breed dogs'barks could be recognized and the data of spectrogram, especially formant contour, could be used to discriminate the sender characteristics. The body postures could also be used to understand their mind.

The microstructure and mechanical properties of concrete will degrade significantly at high temperatures, thus affecting the bond strength between reinforcing steel and surrounding concrete in reinforced concrete members. In this study, the effect of individual and hybrid fiber on the local bond-slip behavior of lightweight aggregate concrete (LWAC) after exposure to elevated temperatures was experimentally investigated. Tests were conducted on local pullout specimens (150 mm cubes) with a reinforcing bar embedded in the center section. The embedment lengths of the pullout specimens were 4.2 times the bar diameter. The parameters investigated included concrete type (control group: ordinary LWAC; experimental group: fiber reinforced LWAC), concrete strength, fiber type, and targeted temperature. The test results showed that for medium-strength LWACs exposed to high temperatures, the use of only steel fibers did not significantly increase the residual bond strength. Moreover, the addition of individual and hybrid fiber had little effect on the residual bond strength of the high-strength LWAC after exposure to a temperature of 800℃.

The extraction and recognition of human motion characteristics need to combine biometrics to determine and judge human behavior in the movement and distinguish individual identities. The so-called biometric technology, the specific operation is the use of the body's inherent biological characteristics of individual identity authentication, the most noteworthy feature is the invariance and uniqueness. In the past, the behavior recognition technology based on the single characteristic was too restrictive, in this paper, we proposed a mixed feature which combined global silhouette feature and local optical flow feature, and this combined representation was used for human action recognition. And we will use the KTH database to train and test the recognition system. Experiments have been very desirable results.

The present research aims to examine whether learning from the supervisor influences readiness for change with the mediating impact of planfulness. Drawing upon the theory of planned behavior, it is hypothesized that learning from the supervisor positively impacts planfulness ability in individuals, which in turn enhances the readiness for change. Through using convenience sampling, the sample of 451 was collected from employees working full-time in the manufacturing and I.T. service organizations in India. Structural equation modeling and regression analysis indicate that learning from the supervisor is positively associated with readiness for change and planfulness. Additionally, planfulness fully mediated the relationship between learning from the supervisor and readiness to change. The findings of the present research highlight that continuous support and learning from the supervisor enhances the planfulness ability of the individual and consequently enhances individual readiness for change. The current research is pioneering in testing the hypothetical model associating learning from the supervisor, planfulness, and readiness for change.

This paper discusses issues faced by individual building industry clients. These form the majority of clients but, because they do not possess high purchasing power, they attract less attention in the industry. Given that key decisions on project definition and procurement strategy are made at the pre-project stage, the industry would benefit from knowing relevant aspects of its clients' attitudes and behaviors, so that it can support them. There is a lack of research on this subject, and so we first describe a theoretical framework and research methodology that were developed for this specific group of clients. Theory adopted from consumer behavioral research was introduced to develop a general behavioral model of individual clients. In this model, individual clients are assumed to seek and then process information after acknowledging normative activities. To validate our model, a field survey was conducted using randomly selected individual clients. Their opinions on the importance and difficulty of 12 normative activities were analysed to establish a general attitude. Information seeking behaviour was investigated by measuring the frequency and type of source that they contacted to conduct the normative activities. The attitudes and information seeking behaviour presented in this research will contribute to the development of project tools for supporting these clients.

As information security(IS) is recognized as an organization's core value, organizations are making efforts to adopt strict IS policies and technologies. However, strict IS policies can cause negative behavior for employees of organizations who need to apply IS to their work. This study confirms that IS can express the role stress of employees, and suggests a way to mitigate the IS role stress. Specifically, we confirm that organization justice and individual social identity can reduce IS role stress, which reduces IS voice behavior. In the study, we surveyed workers of organizations that applied IS policies to their work and obtained 318 samples. Also, we tested the hypothesis by applying the structural equation model. As a result, IS organization justice increased IS voice behavior through social identity and partially reduced IS voice behavior by mitigating IS role stress. In addition, social identity moderated the relationship between IS role stress and IS voice behavior. This study suggests strategies for achieving internal IS goals by suggesting conditions for mitigating IS role stress from an organizational and individual perspective.
