This study proposes a comprehensive model of purchasing intention of customers in agricultural products online shopping malls. In this study, we derived the factors through the literature reviews and logical reasoning and classified the factors as a business point of view, an information systems point of view and an agricultural characteristics point of view, and developed the integrated research model which is the factors affect purchase intentions by mediating trust and the perceived usefulness. A total of 329 samples of a valid survey data from the members of small agricultural online shopping malls were collected and the research model was empirically analyzed by a confirmatory factor analysis and path analyses using structural equation modeling with the data. The results show that the product quality and the service quality of the business point of view have effects on the trust, however the price adequacy and entertainment have no effect on the trust and the perceived usefulness respectively, also the advertising exposure has no effect on the trust but it has an effect on the purchase intention directly. The information quality and the ease of use of the information systems point of view have an effect on the trust and perceived usefulness. At last, the seasonal product of the agricultural characteristics point of view has effects on perceived usefulness but the regional brand has no effect on the trust. The results of this study provide strategic implications for successful development and operation of agricultural products online shopping malls.
According to the development of new Information Technologies, firms consistently invest a significant amount of money in IT activities, such as establishing internal and external information systems. However, several anti-Information activities-such as hacking, leakage of information and system destruction-are also rapidly increasing, thus many firms are exposed to direct and indirect threats. Therefore, firms try to establish information security systems and manage these systems more effectively via an enterprise perspective. However, stakeholders or some managers have negative opinions about information security systems. Therefore, in this research, we study the relationship between multibusiness firms' performance and information security systems. Information security indicates physical and logical correspondence of information system department against threats and disaster. Studies on information security systems suggested frameworks such as IT Governance Cube and COBIT Framework to identify information security systems. Thus, this study define that information security systems is a controlled system on enterprise IT process and resource on IT Governance perspective rather than independent domain of IT. Thus, Information Security Systems should be understood as a subordinate concept of IT and business processes. In addition, this study incorporates information capability to information security system literature to show the positive relationship between Information Security Systems and Corporate Performance. The concept of information capability suggested that an interaction of human, information, technical and an effect on corporate performance using three types of capability (IT Practice, Information Management Practice, Information Behaviors and Values). Information capability is about firms' capability to manage IT infrastructure and information as well as individual employees who use IT infrastructure and information. Thus, this study uses information capability as a mediating variable for the relationship between information security systems and firms' performance. To investigate the relationship between Information Security Systems and multibusiness firms' performance, this study extends the IT relatedness concept into Information Security Systems. IT relatedness provides understanding of how corporations cope with conflicts between headquarters and business units to create a synergy effect and achieve high performance using IT resources. Based on the previous literature, this study develops the IT Security Relatedness model. IT Security Relatedness is our main independent variable, while Information Capability and Information Security Performance are mediating variables. To control for the common method bias, we collect each multibusiness firm's financial performance and use it as our dependent variable. We find that Information Security Systems influence Information Capability and Information Security Performance positively, and these two variables consequently influence Corporate Performance positively. In addition, this result indirectly shows that corporations under a multibusiness environment can obtain synergy effects using the integrated Information Security Systems. This positive impact of Information Security Systems on multibusiness firms' performance has an important implication to various stakeholders. Therefore, multibusiness firms need to establish Information Security Systems to achieve better financial performance.

The purpose of this study is to develop a model of the TOC (Table of Contents)-based research record system and to comparatively analyze its usability, in order to comprehensively and systematically manage and practically use the various research records generated from the entire process of research and development. For this purpose, the templates for technical recording and the components of each item were proposed to enable technical recording based on TOC, and structured contents were designed to organically connect between these TOC technical records and existing research records. Also, a database logical schema was developed to design a database, and a test collection was constructed on the basis of research records and TOC technical records. Finally, the model of research record system was constructed by designing TOC record search system and user interface including integrated search system. Based on this model, the usability assessment was performed by comparing the existing distributed general systems with the TOC-based research record system. As a result of the comparative analysis of these two systems, the TOC-based research record system showed generally higher utilization of research records than the general systems.
For playing a multimedia presentation in a Internet, the case that the presentation QoS(Quality of Services) at a destination nay be different from the QoS of multimedia data at the source occurs frequently. In this case, the process of trancoding the multimedia data at the source Into the multimedia data satisfying the QoS at the destination should be requited. In addition, even the presentation description having the homogeneous QoS at both sides may have different transcoding paths due to the limitation of display terminals or network bandwidth. That is, for a multimedia description, it is required to regenerate a proper transcoding path whenever the displaying terminals or the network environment gets decided. And the delay time required to go through the transcoding path may affect the playability of the give presentation. Therefore it should be checked whether the presentation requiring a transcoding process is able to be played in a real time. In this paper, the algorithm for generating all the possible transcoding paths for a given multimedia description under a fixed set of transcoders and the network environment is proposed. The algorithm adopts the concept of QoS transition diagram to Prevent from a trancoding Path being cycled by the repetition of a cyclic Path which generates the same QoS of multimedia data as its input QoS. By eliminating all the cyclic Paths, the algorithm can guarantee the termination of the process. And for the playability check, a method of computing the transcoding time and the delay lime between logical data units are proposed.Finally all the proposed methods were implemented in the stream engine, called TransCore and the presentation-authoring tool, called VIP, we had developed. And the test results with sample scenarios were presented at the last.
As a preliminary investigation to obtain useful auto- and allopolyploids a ten year old tetraploid of Pinus densiflora induced from the colchicine treated seed was observed on the cytological, morphological and physioa logical characters in the present study and the results can be summarized as follows. 1. The number of chromosome at the base of needle was 48 so that it was recognized as a tetraploid. 2. The needles were thicker and the number of them on an individual was less than the 2n plant. The needle combined to a single was appeared 2%. 3. No difference was found in the number of stomata rows on the central part of needle between the tetraploid and 2n plant, however, guard cells of tetraploid increased 36% in the long diameter compared with 2n plant. 4. Microsporangiate storbile developed normally showing the same size with 2n plant while the size of pollen grain increased about 20% larger than 2n plant. 5. Germination percentage in vitro increased until 17 hours but decreased after 26 hours compared with 2n plant. The longest length of pollen tube during the germination period appeared in the tetraploid pollen.

It is crucial In decision making to select a project delivery system (PDS) adjusted accordingly to the project characteristics. Furthermore, selecting a tendering system is the kernel in the process of selecting PDS. In October 2007, the Ministry of Finance and the Economy of Korea launched two new project delivery systems, "Best Value Contract (Design-Bid-Build)" and "Bridging Contracts (Design-Build)" by revising enforcement ordinances of "Act on Contracts to Which the State is a Party" to provoke the tendering systems. In order to support the proposed purpose, this research developed a selection model for suitable tendering system, which helps a public owner select a tendering system appropriate to the project characteristics. First, the framework of the model was set throughout analyzing previous researches and interviewing relevant experts. Additionally, by analyzing the survey result from 265 experts engaged in architectural and civil engineering business, the relative weights of the selection factors and the effectiveness values of the alternatives were suggested as the quantitative evaluation references. Finally, the practical guideline was suggested to apply this model to three public projects scheduled to be delivered. The result of applying the model to three case projects showed that further researches were needed to make the selection process logical and to suggest the standard weights and effectiveness values according to project type.
This Paper aims to elaborate on the origin of thinking mind. And this is a cooperative project between philosophy and neuroscience and brain science. I have written this paper in admiration for the achievements of twentieth century neuroscience and brain science, and out of desire to assist the subject in future. Much of the history of modern philosophy, from Descartes and Kant forward, consists of failed models of brain. As Edward O. Wilson precisely said, the shortcoming is not the fault of the philosophers, who have doggedly pushed their methods to the limit, but a straightforward consequence of the biological evolution of the brain. Guiding that investigation down pathways that will illuminate brain research is a task of neuroscience and brain science. Investigating logical relations among concepts is a philosophical task. If we are to understand the neural structures and dynamics that make perception, thought, intentional behaviour possible, clarity about these concepts and categories and their relations is essential. Hence our joint venture of philosophy and science. Sure, it is human beings that perceives, not parts of its brain. And it is human beings that who think and reason, not their brain. But the brain and its activities make it possible for human beings-not for it-to perceive and think, to feel emotions, and to form and pursue projects. Thus We try to investigate and reveal the origin of thinking mind as follow: 1) The difference between chimpanzee and human beings 2) brain and mind 3) the origin of thinking 4) the wisdom of nature.

This thesis explores how JobGeuk ShimChungWangWhoJeon and the Devoted daughter ShimChungJeon scenario have transformed ShimChungJeon, a notable work of Pansori literature, dramatically for modern times. By analyzing the adapter's consciousness and changing direction in these two works, it was found that ShimChungJeon was tailored to audiences in the 1900s. JobGeuk and the scenario are attempts to transform ShimChungJeon to meet cultural needs in the 21st century and to make the works appealing to the public. The aspects of the transformation of JobGeuk ShimChungWangWhoJeon are 1) reinforcement of logical causality, 2) weakening the humor and simultaneously emphasizing the work's surreal nature, and 3) dramatic expression by song. The aspects of the change in direction of the Devoted daughter ShimChungJeon scenario are 1)the insertion of a new narrative, 2)trying to evoke both humor and tragic sadness, 3)seeking newness with the reassignment of time and events. JobGeuk ShimChungWangWhoJeon is the first example of the transformation of ShimChungJeon's dramatic style and Devoted daughter ShimChungJeon is the first transformation of its scenario. These two works show how ShimChungJeon can be adapted to modern times and new cultures, and how ShimChungJeon can be made relevant and be enjoyed by the public regardless of the era.
${\ll}$Hua shu${\gg}$ is one of the Taoist scriptures written by Tan qiao, a taoist in the late Tang dynasty. The logical structure of his scriptures is very complicated, and its content is profound though it has few pages. To understand ${\ll}$Hua shu${\gg}$ precisely the key words which appear in the Taoism scriptures have been examined. The most important words are: 'Tao', 'Emptiness', 'Shape', and 'Variation'. Tan qiao tried to explain nature, human, and society changes by using these key words, and also asserted that humans can affect their change; we slow our aging, more or less; we prevent our society from its decay and make it stable, more or less. Tan qiao asserted the autonomous feature of humans in ${\ll}$Hua shu${\gg}$ which shows how man manages his own life rather than being stuck in his destiny. This goes the same for society. "One's destiny is not fixed but changeable through his efforts". In Taoism, humans are not beings who have no chance to make change other than living their given destinies but are autonomous. This is again what the Taoist Tan qiao wanted to make clear.
Plato said that our cosmos was created from the union of nous and $anank{\bar{e}}$ in Timaeus. In addition to this, 'the third kind', namely $ch{\bar{o}}ra$, exists already with genesis before the birth of the cosmos. Plato explains this $ch{\bar{o}}ra$ with several metaphors. That is, 'receptacle', 'mother', 'gold', 'space', 'place' etc. From Aristotle to contemporary scholars, generally three types of interpretations are presented. First, $ch{\bar{o}}ra$ is a kind of a 'void.' Secondly, $ch{\bar{o}}ra$ is Aristotle's $prot{\bar{e}}$$hyl{\bar{e}}$. Thirdly, $ch{\bar{o}}ra$ has two aspects of space and matter. I will accept the third opinion. Plato's $ch{\bar{o}}ra$ has both a spatial aspect and material aspect. $Ch{\bar{o}}ra$ is a place that accommodates all sensible things in itself. On the other hand, $ch{\bar{o}}ra$ seems to be a mother who nourishes sensible things like a child. In this, Plato lacks a logical consistency. The research of $ch{\bar{o}}ra$ can not deviate from the limits of $eik{\bar{o}}s$ logos.
