This study investigates the effect of nonverbal communication on trust, switching barrier, and repurchase intention. Sample subjects used in this study were customers of a fashion shop in Sunchon. The questionnaires were conveniently sampled from July 2010 to August 2010. Questionnaire data from 335 customers of a national brand were analyzed through a reliability analysis, factor analysis, and multiple regression analysis. The results of this study are as follows. First, nonverbal communication by the service provider was divided into 3 types, physical appearance and paralanguage, postures and proxemics, and facial expressions. Second, it was found that physical appearance and paralanguage, postures and proxemics, facial expression of nonverbal communication had a significant impact on customer trust. Third, given the relationship between nonverbal communication and switching barrier, it was represented that the postures and proxemics and facial expressions (except physical appearance and paralanguage) had a significantly positive influence on the switching barrier. Forth, physical appearance/paralanguage, postures/proxemics, and facial expressions (nonverbal communication) had a positive influence on repurchase intention. Fifth, given the relationship between trust and repurchase intention as well as switching barrier and repurchase intention, it was represented that trust and switching barrier have a significantly positive influence upon repurchase intention. According to the results of this study, the more positive nonverbal communication by the service provider then the higher the customer repurchase intention as well as trust and switching barrier. Fifth, given the relationship between trust and repurchase intention as well as switching barrier and repurchase intention, it was represented that trust and switching barrier have a significantly positive influence upon repurchase intentions.

The cerebral microvessels possess barrier characteristics which are tightly sealed excluding many toxic substances and protecting neural tissues. The specialized blood-neural barriers as well as the cerebral microvascular barrier are recognized in the retina, inner ear, spinal cord, and cerebrospinal fluid. Microvascular endothelial cells in the brain closely interact with other components such as astrocytes, pericytes, perivascular microglia and neurons to form functional 'neurovascular unit'. Communication between endothelial cells and other surrounding cells enhances the barrier functions, consequently resulting in maintenance and elaboration of proper brain homeostasis. Furthermore, the disruption of the neurovascular unit is closely involved in cerebrovascular disorders. In this review, we focus on the location and function of these various blood-neural barriers, and the importance of the cell-to-cell communication for development and maintenance of the barrier integrity at the neurovascular unit. We also demonstrate the close relation between the alteration of the blood-neural barriers and cerebrovascular disorders.

This study was designated to investigate communication barriers of nurses in clinical settings. This study was done in 2 phases, first content analysis on descriptions of 50 nurses in three general hospitals and 40 nursing students on communication barriers for nurses in clinical settings, and second a survey to investigate the factors related to communication barriers and the relation between the nurse's characteristics and the extent of communication barriers in clinical settings from two nurses educators, 13 nursing students who experienced clinical practice and 71 nurses in 11 general hospitals. The results are as follows : 1. Through content analysis, 11 properties of communication barriers for nurses in clinical settings were identified. These were inappropriate communication style as a nurse, lack of professionalism, in appropriate control of emotions, lack of knowledge about the clincal setting, the lack of preparation about content of communication, the problem in trust relation, differences in priorities in needs, uncontroleable situation for nurses, inappropriate nurses' perception about patients, conflict with medical team and inadequate systematic support were identified and grouped in to four categories, communicator, message, feed-back and communication context. 2. The four factors in communication barriers for nurses in the clinical setting were identified and named as ambiguity in the nurses' position, lack of confidence, difference in perspectives with patients and in-adequate nurse-patient relationship. 3. There was a significant difference(F=5.31, P=0.0022, F=3.62, P=0.0316, F=2.80, P=0.067, F=9.01, P=0.0003) among the groups according to work place in rating the extent of the communication barrier in the clinical setting and in the four factors, the nurses working in the psychiatric patient unit rated the communication barrier in the clinical setting lowest among the groups. There was a significant negative correlation between the length of the nurses's carrier and the extent of communication barrier in three factors, ambiguity in the nurses' position, lack of confidence and inadequate nurse-patient relationship.

Purpose: This study was conducted to investigate ICU nurses' perceptions of communication difficulties, the importance of and satisfaction with communication with doctors, other nurses, patients, and family, as well as to explore communication barrier with patient families. Methods: Investigators developed a 15-item communication perception questionnaire and 58-item communication barrier questionnaire. Communication barrier included 4 domains: nurses, family, environment, and patient condition. A total of 151 ICU nurses with a minimum of one year of ICU experience participated. Results: ICU patients ($3.38{\pm}0.73$) were the most difficult group to communicate with, followed by family ($3.32{\pm}0.72$), senior nurses ($3.25{\pm}0.74$), doctors ($3.21{\pm}0.68$), and nurse colleagues ($2.64{\pm}0.73$). Doctors ($4.61{\pm}0.53$) were the most important group to communicate with, followed by nurse colleagues ($4.52{\pm}0.54$), patients ($4.49{\pm}0.58$), senior nurses ($4.44{\pm}0.55$), and family ($4.43{\pm}0.61$). Satisfaction with communication was the highest with colleague nurses ($3.60{\pm}0.68$), then senior nurses ($3.37{\pm}0.74$), family ($3.18{\pm}0.71$), patients ($3.09{\pm}0.75$), and doctors ($3.06{\pm}0.83$).The total score of the communication barrier was $2.83{\pm}0.52$, where each domain was scored as follows: patient condition $3.13{\pm}0.74$, nurses $2.83{\pm}0.60$, environment $2.81{\pm}0.66$, and family $2.76{\pm}0.57$. The ICU nurses reported that communication was difficult due to 'sudden deterioration in the patient's condition', 'being too busy', 'a noisy environment', and 'information not being shared between family members.' Significant differences were noted by age, clinical experience, and marital status of nurse respondents. Conclusion: The findings indicated that development of a protocol on communication between nurses and doctors as well as development of an educational program on communication skills are necessary.

To investigate the reliability of the MTJs on the roughness of insulating tunnel barrier, we prepared two MTJs with the different uniformity of barrier thickness. Namely, the one has uniform insulating barrier thickness; the other has non-uniform insulating barrier thickness as compared to different thing. As to depositing amorphous layer CoZrNb under the pinning layer IrMn, we achieved MTJ with uniform barrier thickness. Toinvestigate the reliability of the MTJs dependent on the bottom electrode, time-dependent dielectric breakdown (TDDB) measurements were carried out under constant voltage stress. The Weibull fit of out data shows clearly that $t_{BD}$ scales with the thickness uniformity of MTJs tunnel barrier. Assuming a linear dependence of log($t_{BD}$) on stress voltages, we obtained the lifetime of $10^4$years at a operating voltage of 0.4 V at MTJs comprising CoNbZr layers. This study shows that the reliabilityof new MTJs structure was improved due to the ultra smooth barrier, because the surface roughness of the bottom electrode influenced the uniformity of tunnel barrier.

To research the characteristics of $TiO_2$ as an insulator, $TiO_2$ films were prepared with various annealing temperatures. It was researched the currents of $TiO_2$ films with Schottky barriers in accordance with the contact's properties. The potential barrier depends on the Schottky barrier and the current decreases with increasing the potential barrier of $TiO_2$ thin film. The current of $TiO_2$ film annealed at $110^{\circ}C$ was the lowest and the carrier density was decreased and the resistivity was increased with increasing the hall mobility. The Schottky contact is an important factor to become semiconductor device, the potential barrier is proportional to the hall mobility, and the hall mobility increased with increasing the potential barrier and became more insulator properties. The reason of having the high mobility in the thin films in spite of the lowest carrier concentration is that the conduction mechanism in the thin films is due to the band-to-band tunneling phenomenon of electrons.

The present study is a descriptive study to investigate nurses’perception of barriers to research utilization. A total of 274 participants in this study consisted of registered nurses working in a large, urban and academic medical center. A questionnaire packet containing the Barriers Scale, and a demographic profile was distributed to nurses and they were asked to return the packet to a return-box in the Nursing Office after completion. The greatest barrier was insufficient time on the job to implement new ideas. Next was ‘implications for practice are not made clear'. Also the item of the English language in research articles was considered to be the ninth barrier. The greatest mean score of each of the sub-scales was the communication factor. The were followed by the organization, research, and nurse factors. Compared with the means from other studies, the mean scores of the communication and research factors were higher in this study. Nurses who had not taken a class of research methods found the communication and research factors as a higher barrier than those who did. Also, nurses who did not participate in a conference last year perceived the research factor as higher than those who did. It is recommended that English and research classes should be strengthened in educational nursing programs. The researchers should also describe the section of implication for practice as more detail and clearer for the understanding of nurses; Lastly journals in a libraries or online journal systems should be easily accessible.

We studied the Drain-Induced-Barrier-Lowering (DIBL) effect by different drain engineering. One other drain engineering is symmetric source-drain n-channel MOSFETs (SSD NMOSs), the other drain engineering is asymmetric source-drain n-channel MOSFETs (ASD NMOSs). Devices were fabricated using state of art 40 nm dynamic-random-access-memory (DRAM) technology. These devices have different modes which are deep drain junction mode in SSD NMOSs and shallow drain junction mode in ASD NMOSs. The shallow drain junction mode means that drain is only Lightly-Doped-Drain (LDD). The deep drain junction mode means that drain have same process with source. The threshold voltage gap between low drain voltage ($V_D$=0.05V) and high drain voltage ($V_D$=3V) is 0.088V in shallow drain junction mode and 0.615V in deep drain junction mode at $0.16{\mu}m$ of gate length. The DIBL coefficients are 26.5 mV/V in shallow drain junction mode and 205.7 mV/V in deep drain junction mode. These experimental results present that DIBL effect is higher in deep drain junction mode than shallow drain junction mode. These results are caused that ASD NMOSs have low drain doping level and low lateral electric field.
