MCDD performs demultiplexing and demodulation of multi-carrier signals for signal processing schemes such as switching, channel encoding and remodulation in an OBP satellite. During the demultiplexing procedure, several factors such as frequency offset and/or quantization error degrade BER performance. Hence, influences of those factors should be reduced. A influence of the frequency offset can be reduced by inserting guard band between channels, and that of quantization error can be decreased by quantization level control. In case that the data rate of system is not limited, the guard band and the quantization level do not affect each other. In the other case, however, mutual influence between them should be considered. In this paper, we observe the mutual influence when the data rate of the MCDD is limited, and analyze the BER performance.

Purpose: study of the mutual influence of the individual anatomical regions damage in patients associated with falls from heights. Methods: 561 medical reports of patients associated with falls from heights admitted to Republican Research Center of Emergency Medicine (RRCEM), in period of 2010-2013 yy, were analyzed retrospectively. Patient's age range was from 15 to 89. Treatment of these patients held in three stages: period of acute disorders of vital functions; relative stabilization period; stabilization of vital functions. The scope and content of medical diagnostic procedures performed on pre-hospital and intensive care stages. The severity of each injury was scored according to the AIS scale, the total severity of lesions was scored by points due to ISS. Digital material is treated by methods of mathematical statistics. Results: Falls from heights leads to associated injuries for 4 times more than isolated trauma, and increases according to height of fall and falling surface. Patients with TBI+chest trauma, are most serious contingent that has highest mortality and complications (36.8%). TBI+musculoskeletal system trauma are characterized by high blood loss, traumatic shock and fat embolism, forming a vicious circle. Conclusion: in patients associated with falls from heights clinical manifestations of injuries mutual aggravation syndrome will be seen. TBI leads to complication of chest trauma, delayed diagnostics of abdominal and chest trauma, aggravation of coma condition. Developing of high blood loss and fat embolism in musculoskeletal system trauma leads to shock and pulmonary embolism, which increases probability of death in the presence of abdominal or chest trauma, but abdominal trauma or chest trauma has no significant effect on the severity of the musculoskeletal system trauma.

Radiation efficiency and antenna gain, in this paper, can be increased by the slot on EMI shield painted on the mobile phone back cover. When the EMI slot which has proper dimension and location is located on the EMI paining area in the phone, the increment of antenna current density due to mutual coupling between the antenna and slot derives increment of antenna efficiency. For the verification of EMI slot effect, we apply the EMI slot to the mobile phone which is operating on GSM/DCS/USPCS/WCDMA quad band, and measure $S_{11}$ and antenna efficiency. It's shown that resonant frequency is not changed and radiation efficiencies to frequency channels by EMI slot are increased from 0.21 % to 8.96 %.

This is a study on the application of a dialectic way of thinking in terms of design methods, and has contents about the formation of new visual and the ways of process that are triggered by cognitive introspection. A ccordingly, the study has its purposes in interpretation and recommendation of new methodological systems around dialectic principles and ways of thinking on the works of the Dutch Architecture Exhibition carried out in Korea in 2013, with the theme of "Reuse" among the aspects expanding since the reflexive modernization. Firstly, the basic features of Dutch designs were connected to dialectic ways of thinking. After studying the basic concepts of dialectics from Greek philosophies to Kant, Hegel, Marx and Benjamin, the aspects of applying them onto creative works such as art, architecture and design were methodologically systematized. Through this process, it was confirmed that the existing concepts are newly rearranged rationally, logically and scientifically based on dialectic ways of thinking rather than subjectively or emotionally. From the study of the 12 art works, it was confirmed that the value of use and potential obstacles have been used as a design solution. Also, the process which is juxtaposed with the result by itself has been expressed and causes the alienation effect. Therefore, such dialectic ways of thinking was organized into a procedural flow of contradictory recognition on situations, drive due to negativity, mutual penetration, mutual transformation, abstraction, verbalizing and creation of new concepts, and it was confirmed that such finding was valid in securing creative possibilities as 'New Uses' rather than 'Re-uses'.

SCM system is a strategic cooperative that organically integrates all supply chains to improve the performance of a company. For effective SCM system, emphasis is placed on securing long-term, mutual relationships and change management. The implementation of an SCM system is likely to introduce a wide range of changes in and across member organizations and these changes are likely to be met with scepticism and resistance by individuals and organizations in the chain. Thus, the success of an SCM system cannot be guaranteed without effective change management. And we adopted the concept of information orientation (IO) as our method to measure the performance of an SCM system through information quality and information sharing. Therefore, this study examined the influence of mutual, reciprocal relationships among change management on information capability through information quality and information Sharing. The results of this study can be summarized as follows. First, change management had a significant influence on information quality, information Sharing and information capability. Second, information quality had a significant influence on information Sharing and information capability. Third, information sharing had a significant influence on information capability.

The purpose of this study is to examine demographic characteristics, psychological characteristics and patterns of supportive relationships with their children that affect the successful lives of the elderly. A survey was conducted of 410 people aged between 65 and 85, and 405 samples were used for the analysis. First, the supportive relation between the elderly and their children was categorized into four groups depending on the total amount and direction of support. The four groups consisted of the elderly who exchanged little or no support, those who only received support from their children, those who only gave support, and those who both gave and received support. Second, the more the elderly exchanged support and gave emotional support to their children, the better the chance that the elderly would lead a successful life in later years. Third, subjective health conditions most significantly affected the successful lives of the elderly who exchanged little or no support. The level of education was most significant for the elderly who only received support. The level of housing satisfaction mostly affected the elderly who only gave support. Mutual support primarily affected the elderly who both gave and received. Thus, we should provide health programs for the elderly who exchange little or no support to encourage a healthier lifestyle. In addition, opportunities for continuing education should be provided for the elderly who only receive support to make up any deficiency in education. Because spouses are mostly affected for those elderly who exchange little or no support and the elderly who only receive support, we should provide educational programs about how to be better lifetime companions to each other and also provide medical and in-home care for the remaining spouse even after the other partner is gone. Because housing satisfaction greatly affects the elderly who only give support, improvements in the residential environment are essential. Since the level of mutual support is crucial to the elderly who both give and receive support, programs on the development of human resources are needed for the elderly to interact dynamically and intimately with their children.

Fin-type SONOS (silicon-oxide-nitride-oxide-silicon) flash memory has emerged as novel devices having superior controls over short channel effects(SCE) than the conventional SONOS flash memory devices. However despite these advantages, these also exhibit undesirable characteristics such as corner effect. Usually, the corner effect deteriorates the performance by increasing the leakage current. In this paper, the corner effect of fin-type SONOS flash memory devices is investigate by 3D Process and device simulation and their electrical characteristics are compared to conventional SONOS devices. The corner effect has been observed in fin-type SONOS device. The reason why the memory characteristic in fin-type SONOS flash memory device is not improved, might be due to existing undesirable effect such as corner effect as well as the mutual interference of electric field in the fin-type structure as reported previously.

Purpose: This study was done to examine actor and partner effect of dementia knowledge, self-efficacy and depression on dementia preventive behavior in elderly couples. Methods: Participants were 115 couples aged 60 years or over who met eligibility criteria. All measures were self-administered. Data were analyzed using SPSS 18.0 and AMOS 18.0 program. Results: Dementia knowledge in elderly couples showed actor and partner effect on dementia preventive behavior. Self-efficacy in the wife did not have direct effects on dementia preventive behavior, but showed indirect effects through dementia knowledge. Self-efficacy in the husband showed direct effects on dementia preventive behavior and indirect effects through dementia knowledge. Wife's depression had direct actor effect on dementia preventive behavior and indirect effect through self-efficacy and dementia knowledge. Husband's depression did not have direct actor effect on dementia preventive behavior, but indirect effect through self-efficacy and dementia knowledge. Effect size of wives' dementia knowledge, self-efficacy and depression on dementia preventive behavior was larger than that of husbands'. Dementia preventive behavior, dementia knowledge and depression had a mutual effect. Conclusion: Results indicate that to promote dementia preventive activity in elderly couples, programs should be conducted for both of the couple, but focused differently for wife and husband.

In this paper, the effect of daily creativity of engineering students on problem-solving ability is addressed through the dual mediating effect of teamwork competency and self-directed learning ability. To this end, a regression-based statistical mediation analysis has been performed on the dual mediation model in which daily creativity and problem solving ability were treated as independent and dependent variables respectively, and teamwork competence and self-directed learning ability were included as mediation variables. The analysis result confirmed that the daily creativity has direct effect on the problem-solving ability, as well as indirect effects through teamwork competence and self-directed learning ability. In particular, the serial mediating effect of teamwork competency and self-directed learning ability was also confirmed to be statistically significant in the relationship between daily creativity and problem-solving ability. This verifies that problem-solving ability can be improved not only directly by improving daily creativity but also indirectly by improving teamwork competence and self-directed learning ability. In addition, teamwork competency showed greater indirect effect on problem-solving ability than self-directed learning ability, so increasing teamwork competency has a more significant effect on improving problem-solving ability than increasing self-directed learning ability. Therefore, in order to develop better problem-solving ability, it is necessary to identify and improve the learners' teamwork competency first and to strive to create an environment where learners can solve problems based on mutual trust with their teammates.

This study recognized the mutual collaborative characteristics among consultants as important factors in the performance of the government-supported consulting business, and wanted to look at the impact of the cooperative characteristics among consultants on the consulting performance. First, a research model was presented based on theoretical background, hypotheses were set up and surveyed, and hypotheses were verified by multi-circulation analysis. Among the collaboration characteristics among consultants, the most influential was mutual reliable followed by smooth communication, professional competence and role sharing. information sharing was rejected and was found to be relatively less affected than other variables. This can be seen as more important than the quantitative aspect of information sharing because of the collaborative nature of consultants who must work toward common goals. Collaboration among consultants has been positive when carrying out government-funded consulting projects, suggesting that quantitative characteristics should be considered based on the qualitative characteristics based on mutual reliable. In the future, we hope that this data will be useful for identifying collaborative characteristics among consultants when carrying out consulting projects.
