While a lot of research has been done in the area of the B2C e-commerce, heavily on the Internet shopping, a study on the B2B e-commerce has not been improved enough to be competitive for its importance and practical use. We have studied to build an effective database, attempting to complement and further replace in the long term the off-line distribution channel which has yet to be fully evolve with respect to effectiveness and efficiency. For the building of the effective database, we have gathered information from the related institutions and characterized a fishery channel, and surveyed existing literatures and consumers for deriving factors affecting their purchase intentions and satisfactions. Based upon this survey we constructed the entity-relationship diagram(ERD) which possibly provided some perspectives for the future application. This study focuses on the improvement in the distributional efficiency not only minimizing the intra-organizational conflict and resistance but also maximizing the role function of each party of the organization.

This research aimed to verify organizational culture of resort underlying bottom of organization and shared by employees. Healing-seeking and life style oriented experiences are in prevailing recently, which resort industry insomuch as presumably held from its origin. Unfortunately, it is also widely recognized that resort lost its entity, blurring business domains with hotel industry or yielding integrated resort by imitating theme park. In order to probe organizational culture, in-depth interview with 16 resort experts conducted in resort setting, prepared by Gremeis actant model which is effective in finding myth(story) structure of interviewees. Firstly, interviewer matched six actants with resort business involving-group and asked interviewee to metaphor freely based on 3 night resort experiences. Results showed that sender, receiver, subject, object, helper and opponent were matched with resort, visitor, company, product & service, supporters, and opponent group in orderly manners and also interviewees made each actant into metaphor as healing, patient, medical doctor, medicine, helper and charlatan, respectively. Significance and limitation of research were included in the end of article.

Neuromuscular disorders are common causes of weakness and hypotonia in the infantile period and in childhood. Accurate diagnosis of specific neuromuscular disorders depends first on identification of which aspect of the peripheral neuromuscular system is affected-the motor neuron in the spinal cord, the nerve root or peripheral nerve, the neuromuscular junction, or the muscle-and then on the determination of the etiology and specific clinical entity. Spinal muscular atrophy(SMA) is the most common autosomal-recessive genetic disorder lethal to infants. The three major childhood-onset forms of SMA are now usually called type I, type II and typeⅢ. Progression of the disease is due to loss of anterior horn cells, thought to be caused by apoptosis. Diagnosis is based on the course of the illness, as well as certain changes seen on nerve and muscle biopsy and electrodiagnostic studies. More recently, our understanding of the genetics of this disorder has provided a noninvasive approach to diagnosis. We report on a 3-year-old male patient with spinal muscular atrophy type II. He had progressive muscular weakness since 18 months of age. The upper arms were slightly, and the thighs moderately atrophic. There was muscle weakness of both the upper and lower limbs, being more proximal in distribution. Electromyogram revealed a neurogenic pattern.

Typical hypoplastic left heart syndrome(HLHS) is a distinct pathologic entity with aortic atresia, mitral atresia, very hypoplastic or absent left ventricle and thread like ascending aorta. Occasionally, the lesser degree of hypoplasia is found and is called hypoplastic left heart complex(HLHC) by some authors. This HLHC is often associated with critical aortic stenosis. Fetal echocardiography has enabled us to observe human fetal heart in-utero and to diagnose congenital heart disease prenatally over the last 20 years. The diagnosis of HLHS in fetal echocardiography is based on 2-dimensional echocardio -graphic evidence of a diminutive ascending aorta, aortic atresia, mitral atresia or severe stenosis and a hypoplastic left ventricle. Abnormal flow direction through atrial septum or through isthmus greatly aids the diagnosis. This report shows a fetal case who showed hypoplastic left side chambers and retrograde isthmic flow and was diagnosed with hypoplastic left heart syndrome. After birth, although the baby had tachy-dyspnea for the first 3 weeks, she finally recovered without any intervention and showed catch up growth of left side chambers. This case illustrates the extreme difficulty of assessing left ventricle in a fetus.

Ubiquitous computing is a study area explained in a myriad of contexts and technological terms. Payment, however, refers in nature to an act of money transfer from one entity to another, and it is obvious that a payment method will be valued as long as the transaction can be completed with safety no matter what technology was used. The key to U-payment is convenience and security in the transfer of financial information. The purpose of this paper is to find a desirable U-payment scheme by looking at the characteristics of seamlessness under the ubiquitous environments, strong personal device, and peer-based information transactions. We also propose U-SDT Protocol integrating technologies such as Radio Frequency Identification (RFID), Bluetooth, Personal Payment Device, Account Managing Application and Transaction ID as a way to make transactions between users seamless and secure better privacy protection.

Data redundancy is problematic in that it not only induces heavy storage management cost but also could bring critical degradation of information systems. Unfortunately, to our knowledge, only few enterprises willingly afford time and efforts for the faithful conceptual design to prevent the degree of inappropriate data as much as they could, while most of enterprises pay rare attention to the notion of that sort of data quality. Wondering if there would be any other way to design the enterprise.wide data design without prior knowledge about business works is our major motivation for this study. In this paper, we present our data modeling methodology in which associations among objects in each sentences of a business job descriptions are treated as the focal point in database design. A proposed agent for automated design tool simply takes a business job description written in natural language as an input, and then designs an entity relationship diagram with some smart rules. We introduce the scope of the proposed agent and its detailed logics with several examples. And then, we verify the appropriateness of the resulted associations among objects. Lastly, we perform case studies to evaluate the devised agent's applicability to a business field.

We are faced with a paradox in the age of information as finding quality information on the Internet becomes a more challenging task because of information overload. This paper describes the prototype for “IPL-Korea” (Internet Public Library in Korea) project which is an attempt to provide the public with quality information in the form of a metadata system. The system involves cataloging of resources, i.e. websites, that are filtered by library and information science majors as well as information professionals. The user focus of this system is on children, youth, women, and seniors; various classification schemes and resource descriptions relevant for each user group are incorporated into the system to allow efficient browsing of the resources. A thesaurus for “IPL-Korea”, which is based on the ERIC thesaurus, is being constructed for easy manipulation of the breath of searching. The “IPL-Korea” metadata system employs the entity-relationship model in the design of its conceptual schema. Metadata is being stored in the Oracle database system and Web interfaces to this database are provided through ASP, ColdFusion, and JAVA technology.

With the abundance of digital contents, the necessity of precise indexing technology is consistently required. To meet these requirements, the intelligent software entity needs to be the subject of information retrieval and the interoperability among intelligent entities including human must be supported. In this paper, we analyze the unifying framework for multi-modality indexing that Snoek and Worring proposed. Our work investigates the method of improving the authenticity of indexing information in contents-based automated indexing techniques. It supports the creation and control of abstracted high-level indexing information through ontological concepts of Semantic Web skills. Moreover, it attempts to present the fundamental model that allows interoperability between human and machine and between machine and machine. The memory-residence model of processing ontology is inappropriate in order to take-in an enormous amount of indexing information. The use of ontology repository and inference engine is required for consistent retrieval and reasoning of logically expressed knowledge. Our work presents an experiment for storing and retrieving the designed knowledge by using the Minerva ontology repository, which demonstrates satisfied techniques and efficient requirements. At last, the efficient indexing possibility with related research is also considered.

The purpose of this study was to propose the developmental direction for small libraries based on a set of various situational analysis of small libraries in Seoul. By analyzing the operational status of the autonomous regions of different operating methods, we also pursued qualitative enhancement of small libraries by autonomous district by proposing optimized operation methods. As a consequence of the study, it was analyzed that the public and private libraries need to be distinguished in consideration of the characteristics of operation according to the operating entity rather than uniform budget support and guidance management. That is, the small libraries scattered throughout Seoul were founded by the principal of their establishment for the purpose of providing knowledge information and reading culture service within the public activity area. Therefore, if Seoul intervenes and manages under the current situation, where the libraries are operating independently in accordance with the purpose of establishment, regardless of whether they meet the user requirements or not in terms of quality or quantity, various problems may be caused. In this background, it seems appropriate to restrict the library management in line with relevant regulations.

In bulding Intelligent Agent Societies (IAS), it is very important to design and implement coordination in accordance with the known requirement and anticipated working conditions. Coordination consists of a set of mechanisms necessary for the effective operation of IAS. Currently, there is little theoretical support that could help in this research is to generate an empirically-based solving systems in which all agent share an identical goal structure and fully cooperate. And we developed a simulation model called "P-System" which produces basic data to be used for statistical analysis to generate a theory of coordination. Coordination among agent in the P-System is dependent on 23 control variables calld TEs(tweakable emtities.)And the level of coordination is represennted by an independent variabe called QMC (Quality Measure Coordination) expressed in numerical terms according tn the definiion of this study. Also, we have studied how to select unbiased subset from the huge total experimental space of the P-System and how to decide the scale of the subset.
