In order to increase the spectrum efficiency, recently, there is the number of studies for CR technology. For instance, IEEE 802.22 WRAN(Wireless Regional Area Network) WG considered the CR technology as a solution of WRAN system to serve the high speed internet service(1.5 Mbps down stream and 384 kbps up stream) in 100 km overall coverage and 54 MHz-746 MHz band. Basically, in MAC point of view, the WRAN system have been standardizing based on the IEEE 802.16 MAC layer features such as Data transmission method, QoS provision and Bandwidth request schemes. Additionally, the WRAN system further include CR nature functions such as incumbent user protection, self coexistence which would be importantly considered. Also, the inherent WRAN functions are added such as channel bonding and fractional bandwidth usage. This paper mainly explained frame structure, IU protection, self coexistence which are key functions of WRAN system. Finally, in this paper, we expressed a prospect of IEEE 802.22 WRAN standardization.
It is critical to manage risks to complete IS(Information Systems) projects successfully. Identifying risk factors would be the first step for the project risk management. Previous research has discussed the issue with various points of view, such as different risk factors based on project types and roles involved in their projects. This paper empirically explored how people perceive different risk factors by project development methodology, between self-developing IS using programming language like C, Visual Basic and adapting software package already developed by software venders like ERP, CRM packages. There are researches regarding project risk factors for project management in the several point of views. And there are also researches regarding comparison between self-developing and adapting software packages methodology in IS project. However, there are no study on project risk factors comparison between self-developing IS using programming language and adapting software packages already developed by software venders in IS project. This research can be differentiated from previous ones, because it was considered both point of project risk management and development methodology in IS project. This research results implied meaningful messages to enterprise company to be planned IS projects and people who involved in IS projects. They should consider and need to prepare differently according to each development methodology for preventing project risks. It makes them reduce project risks in each case and complete successfully IS projects. Especially, if they have no experiences for implementing software packages, they can forecast the project risks and prepare them in advance.
The purpose of this study is to explore the impact of cultural capital on individuals and society, and to demonstrate the causal relationship between cultural capital and viewing loyalty. Existing studies conducted from a cultural sociological point of view have mainly linked cultural capital to social inequality issues, so the role of cultural capital in personal life and social life has not received attention. To fill this literary gap, this study explored the role of cultural capital centering on the art field. A structural equation model was used to test the research hypotheses, and data were collected for college (graduate) students from three universities in Seoul. As a result of the study, it was found that artistic cultural capital had a significant effect on self-image in the field of personal life. In addition, it was found that artistic cultural capital had a positive effect on tolerant attitudes in the field of social life. Finally, it was found that viewing loyalty, which refers to favorable attitudes and behaviors toward visiting art museums, was significantly affected by artistic cultural capital. The results of this study have academic and practical implications in terms of exploring the practical role of cultural capital.

In venture creation research, studying 'entrepreneurial leadership' is important for uncovering and comprehending the underlying causal process in innovative behavior performance. Although previous studies provide that entrepreneurial leadership enhances followers' innovative behavior, there is few research on entrepreneurial leadership and followers' characteristics interaction. The present study's focus is paradoxical effects of entrepreneurial leadership on self-efficacy and innovative behavior. On the basis of individual regulatory focus, this study suggests that interaction effects of entrepreneurial leadership and followers' regulatory focus differed in promotion view and prevention view followers' innovative behavior. To strengthen the casual mechanism, this study conducted in priming experiment method using employees in SMEs. This study used a 2(entrepreneurial leadership vs. control) x 2 (regulatory focus: promotion vs. prevention) between-participants design. The results of this study provide that (1) Individuals in promotion focus especially benefited from entrepreneurial leadership in terms of its effect on their self-efficacy and innovative behavior; (2) whereas entrepreneurial leadership was negatively related to self-efficacy and innovative behavior of followers' prevention focus. In sum, results of the present study supporting evidence for hypotheses, combined effect of entrepreneurial leadership and regulatory focus on innovative behavior through self-efficacy. Experimental results confirmed hypotheses of this study, revealing that promotion focus show more innovative behavior than prevention focus when their leaders' leadership style is entrepreneurial leadership. Also, the paradoxical effect of entrepreneurial leadership and regulatory focus of followers on innovative behavior was mediated by followers' self-efficacy. This study helps explain how leaders' entrepreneurial leadership boost followers' innovative behavior, particularly for those employees who have promotion focus. The current study contributes to the theory of entrepreneurial leadership and regulatory focus and innovation literature. Findings of this study shed light on the organizational processes that shape innovative behavior in venture/startup corporations and provide contributions for venture business field.
The aim of this research is to examine the main concepts of human beings established by the saints and wise men in the Perennial Philosophy, and to reveal that the human view of Perennial Philosophy is consistent with the view of human beings of Daesoon Thought. In addition, Kant, who synthesizes Western modern philosophy, also sets out the ultimate goal of his philosophy of identifying human beings, wherein Kant asks what human beings are. The view of human beings in the Daesoon Thought reveals one kind of answer that can be given to Kant's anthropological question. If we compare this idea with that of the Western world (a Kantian view of humanity) based on this Perennial Philosophy, the characteristics of Daesoon Thought can be revealed clearly. Kant set the ultimate goal of his philosophy to answer the question, "What is man?" With regards to this, he posits four questions: 1) What can I know? 2) What should I do? 3) What can I hope for? 4) What are human beings? And Kant says that the fourth question (related to anthropology) involves three other questions. However, he does not offer up his own definition of human existence anywhere in his works. He regarded humans as being rational, and he did not think that humans had any special cognitive ability to intuit into humanity itself. In the end, Kant leaves the human being as a sort of unknown entity. On the other hand, The concept of humanity in Daesoon Thought (Perennial Philosophy) can provide a straightforward answer to Kant's question. This possible is because human beings in Daesoon Thought are not seen as different from the Dao (道) or deities (神), which can be called the essence of ultimate reality. From the perspective of Daesoon Thought, humans have divine cognitive abilities. In Perennial Philosophy, this could be the best way to simultaneously lead the object of mind and cognition to the divine Ground. Humans have special cognitive or perceptual abilities. The ultimate identity of every person is God. The realization of the divine being by finding one's true nature as a human being (the self) and the essence of the enlightenment of those who have shown this special intellectual intuition through training are both outcomes found at the core of perennial philosophy. These can be expressed clearly and obviously through the essence of Daesoon Thought.
The purpose of this study is to compare the differences of the career development and the occupational view between giftedness in computer science and normal students in elementary school, so the results of this study provide assistance to the teacher for the direction and guidance on the career education of the giftedness in computer science in elementary school. This survey is based on 82 giftedness in computer science and 167 normal elementary school students. The questionnaires used in the study contain questions asking regarding the career development and the occupational view. The results of this study were as follows : First, according to the consciousness analysis result about career, the giftedness in computer science choose to be scientific technicians, the normal students choose to be artists. The both groups get career information from their parents, but they usually don't get career counseling from teachers. The education of giftedness in computer science does not contribute to changing their dreams, while normal students have no interest in computer science. Second, according to the career development analysis result, in comparison with non-gifted students, the gifted in information science had more success in all domains of career development. Third, according to the occupational view analysis result, the information science gifted students had higher meaningful rate than the normal students. Intrinsic domain' had higher meaningful rate among the subordinate domains, there is no difference in 'extrinsic domain' and 'incidental domain' between the information science gifted students and the normal students. Fourth, according to the correlation analysis result of the career development and the occupational view, there is a positive correlation in all domains of them. The high they are in the career development, the more they have the certain occupational view. Likewise, if they have the certain occupational view, they will be more successful in career development. Based on the findings of this research, the directing and guidance on the career education of giftedness in computer science in elementary school is same as the followings. We should educate parents regarding information about career for students who are under the influence of parents greatly and indicate them to apply to their children appropriately. In addition, for making them to have the positive image of the computer science, teacher should provide more information about the area of information and form various curriculums to induce more interests about computer science. We need to strengthen the career education for guiding the gifted to assist them to establish their own goal and realize them how to study and choose their career in the future. In school education field, it must develop and manage the definite and empirical program, not the career development program which is focused on only entrance into advanced school, to boost self-realization ability and the suitable career education program based on the correct understanding on giftedness in computer science. For this, through steady trying and research, teachers should be eater to develop the career education for students. Also, we have to implement the internal stability career education program, so it will help students to be aware of their job and career; therefore, students will be able to plan and prepare for their career in this rapid changing world.
The purpose of this study was to delve into the work values of dental hygiene students. The subjects in this study were 465 students who attended three different colleges in Gyeonggi province. After a survey was conducted, the collected data were analyzed with SPSSWIN 12.0 program. The findings of the study were as follows: (1) As for the type of work values, the largest group of the students investigated attached importance to pay and reputation, as they gave a mean of 4.18 to those things. In detail, they put the most emphasis on economic compensation since they gave it a mean of 4.42. (2) Regarding their detailed outlook, there was significantly strong positive correlation between their view of achievement and of competency, between their view of economic compensation and of position, and between their view of recognition and of position. (3) As to the impacts of their general characteristics, their work values in pursuit of self-realization was statistically significantly different according to their motivation of choosing dental hygiene(P = .042). Their school(P = .011), academic school year(P = .023), actual work experience as a dental hygienist(P = .045) and motivation of choosing dental hygiene (P = .023) made a statistically significant difference to their contribution- oriented view of occupation. And their work values that accentuated pay and reputation varied statistically significantly with their school(P = .000) and academic school year(P = .000).
A review of this literature and discussions reveal a development of ideas concerning the elements of nursing models. The elements of a nursing model are the nurses view of the human being, nursing's goal, and nursing activities. It has long been recognized that human beings, at one time or another, require nursing care. Varieties of literature were reviewed in regard to the human being as recipient of nursing care through the theory development in nursing. Florence Nightingale initiated the modern era of nursing and described more clearly man as the recipient of nursing care. She looked at man as responding to the laws of nature whether the person was healthy or sick. Henderson added to Nightingale's concept of man , the recipient of nursing care by emphasizing that man is a whole, complete, and independent being. Her view is further specified by her enumeration of the activities the human being must perform. Johnson has developed a very comprehensive view of man as the recipient of nursing care. Man is a behavioral system which has a tendency to achieve and maintain stability in patterns of functioning. Like Nightingale, Johnson sees that similar patterns occur in both health and illness. Johnson postulates that the whole behavioral system of the human is composed of eight sub-systems: affiliative, achievement, aggressive, dependency, eliminative, ingestive, restorative, sexual. Roger's main contribution to the development of nursing models was her emphasis upon unitary man. She pointed out that man is a unified whole, possessing his own integrity and manifesting characteristics that“are more than and different from the sum of his parts.”Rogers focuses on the life processes of the human and points out that these processes have the following characteristics. Wholeness, openness, unidirectionality, pattern and organization, sentence, and thought. According to Roy, man is a biopsychosocial being in constant interaction with a changing environment. To cope with this changing environment, man has certain innate and acquired mechanisms. Man's ability to respond positively or to adapt, depends upon the degree of the change taking place and the state of the person coping with the change. When she analyzes man as an adaptive organism she further describes man as being composed of four adaptive modes: physiological needs, self-concept, role function, and interdependence. Based on the literary review through the theory development in nursing, general approach by a unified nursing model to a view of the recipient of nursing care may be stated as follows: Man is a unified whole composed of subsystems with a flexible and normal line of defense; his internal regulating mechanisms help him to cope with a changing environment; he functions by the principles of homeodynamics.

This study attempts to examine the problem of properties mentioned in Shin Jae hyo's adapted version of Baktaryeong through the property related behavior of the characters, and discuss Shin Jae hyo's view of properties and his contemporary perception problems. As a result, in Baktaryeong, Nolbu takes the shape of a rich farmer in the existing text with grain centered accumulated properties, and of a wealthy man who is skilled in money management and growth as an economically well-informed person. In contrast, Heungbu is a poor peasant isolated from his own farm without enough property to minimally survive, representing the alienated poor who can not adapt to the currency economy led by the Nolbu people. This adaptation could have been a product of Shin Jae hyo's own view of property. Through the detailed description of Baktaryeong, it can be seen that he found it difficult to observe too much, but he thought that interest in property and money seemed basically to be affirmed in human life. In addition, in terms of issues of the poor, he found that the economic efforts of the lower classes and the care of the rich should be needed for the poor. However, he was forced to put the sense of crisis and the self defense consciousness as a wealthy family of middle class in the local society under the rapidly changing circumstances of the time into the text. That is, Baktaryeong included his own diagnosis of the present reality by drawing the issue of wealth and poverty in existing Heungboga(jeon), which is perhaps more appropriate for reality based on Shin Jae hyo's own view of properties.
The purpose of this paper is to study the solvability of the equation (E). In Section 2, we give preliminary definitions. In Section 3, we prove related two results (Theorem 1 and Corollary 1) concerning the closedness property of accretive operators in the class of spaces whose nonempty bounded closed convex subsets have the fixed point property for nonexpansive self-mapping. Using therem 1, we derive a result (Theorem 2) on the range of accetive operators in (.pi.)$_{1}$ spaces with a view to establishing a new result, which improves a result of Kartsatos [8] and Webb [15]. Further, we give an interesting consequence (Corollary 3) of Theorem 2. In section 4, we apply Corollary 1 to obtain two results (Theorem 3 and 4) for the range of sums of two accretive operators, which generalize two results of Reich [12].
