IoT (Internet of Things) is connected to all things Internet-based people and things, things and objects that communicate information between said intelligent technologies and services. Shipping each of a variety of devices that act independently from each other, but, it is actively interlock with each other is not easy practically days. Ship it within the means of communication, the communication between the ship, the communication between ship and shore configuration, SAN (Ship Area Network), RFID/USN, broadband communications, satellite communications and IT technology to a variety of marine environments for the safe navigation the ship's safety management system for the configuration you want to discuss the plan.

In this paper, we propose an experimental environment which can be accessed by remote users, where they can select their preferred operating system, and they can use the Power Controllable systems with full permission to access them. The goal of the proposed systems is to provide an experimental environment for the users to join the international experiment that needs high bandwidth network. In order to do that, we provide high performance systems that is directly connected to back-bone network, and we also provide the ability of users to install any application on various operating system. In addition, we provide the ability to keep continuing the system environment of users in shared system environment. We will show how the proposed systems are useful for the users in terms of the user-efficiency to utilize the environment and the response time for the set-up time. This new proposed environments will provide a new experimental method for the scientists who works for international collaborative experimental researches.

The LEX system is a XML-based framework for medical information consolidation. The Lex makes it possible for heterogeneous HISs(Hospital Information Systems) exchange and share HL7 messages by storing the messages into a single Central Clinical Database. In this paper, we propose a HL7 message server independently interoperable from existing HIS to generate HL7 messages, and design an XML database schema suitable for storing and manipulating such data. We also propose a new DTD for efficient transformation of HL7 messages to XML documents for storage saving as well as supporting patient-oriented information retrieval.

Traffic jams of our country are due to the shortage of roadway as compared with the traffic, however. they are sometimes due to inconsistency of the roadway capacity. Inconsistency of the roadway capacity comes from the difference of cycle length, phase length and number of Phase between major intersection and minor intersection. Specialty increasing number of Phase due to left-turn movements bring out decrease of the arterial capacity, deterioration of the arterial offset. The Purpose of this research is to introduce and analyze the continuous flow intersection to solve the bottleneck of the major intersection. The major contents of this research introduce the concept and design consideration for the continuous flow intersection and also analyze delay, fuel consumption and emissions among multiphase intersection, grade separated intersection and continuous flow intersection. This research analyze the sensitivities according to change of the left-turn traffic volume and also evaluate the cost-effectiveness through the total cost analysis among three of them.

To develop a technique classifying patients based on computerized clinical data followed by validity verification by comparing with nurse's examination. Class scores were determined by nurses for a day on 348 resident patients in 7 wards of a general hospital according to KPCS-1. The class scores were simultaneously evaluated by reviewing the computerized clinical data acquired from the hospital management information system. These two class scores were both significantly different among different departments as well as disease patterns. Intraclass correlation analysis resulted a very high correlation coefficient of 0.96(p<0.01) between the two scoring methods, but the clinical data scores were somewhat higher. An automated patient classification system seemed possible to be developed in future with further enhancement of the present results based on computerized clinical data without manual scoring, which can be applied for performance evaluation as well as workforce planning.

The Basic Semantic Register(BSR) is and official ISO register designed for interoperability among eBusiness and EDI systems. The entities registered in the current BSR are not defined in a machine-understandable way, which renders automatic extraction of structural and relationship information from the register impossible. The purpose of this study is to offer a framework for designing an ontology that can provide semantic interoperability among BSR-based systems by defining data structures and relationships with RDF and OWL, similar meaning by the 'equivalentClass' construct in OWL, the hierachical relationships among classes by the 'subClassOf' construct in RDF schema, definition of any entities in BSR by the 'label' construct in RDF schema, specification of usage guidelines by the 'comment' construct in RDF schema, assignment of classes to BSU's by the 'domain' construct in RDF schema, specification of data types of BSU's by the 'range' construct in RDF schema. Hierarchical relationships among properties in BSR can be expressed using the 'subPropertyOf' in RDF schema. Progress in semantic interoperability can be expected among BSR-based systems through applications of semantic web technology suggested in this study.

In recent years, virtual training has attracted a lot of attention because it is as effective as traditional in-person training and provides more cost-effective and safer learning environment. However, the existing virtual training systems rely on the evaluator's qualitative judgement when evaluating and analyzing trainees' performance. Additionally, evaluation and analysis functions are only available on certain systems so those functions need to be developed for each system. In this paper, we propose an extensible evaluation and analysis system for virtual training using experiential knowledge collected from experts for providing effective evaluation and analysis. Specifically, we provide a method of applying Open API so that the proposed system works with different types of virtual training system. In addition, the experiential knowledge is constructed in advance for the evaluation and analysis so that the efficiency of the evaluation with the comparison target is increased. This experiential knowledge can be quantitatively compared to trainees' performance according to the proposed evaluation and analysis procedures.

Nowadays, given the popularity of wearable devices, The smartwatch is considered as the leading product category and taking the main share of wearable device market. So far smartwatch is only used as an accessorial device of smart phones due to its screen size. The objective of this study is to review literatures and find solutions to overcome the screen limitations. In the literature review, several methods are introduced including using other devices as output devices, other object as screens by projecting technologies, and enlarging screen size by flexible display. Based on that, possible solutions including seamless display and user-centered interaction methods were investigated. Future research directions were also introduced at the end of this study.

Existing fashion web sites show only the search results for one type of clothes in items such as tops and bottoms. As the fashion market grows, consumers are demanding a platform to find a variety of fashion information. To solve this problem, we devised the idea of linking image classification through deep learning with a website and integrating SNS functions. User uploads their own image to the web site and uses the deep learning server to identify, classify and store the image's characteristics. Users can use the stored information to search for the images in various combinations. In addition, communication between users can be actively performed through the SNS function. Through this, the plan to solve the problem of existing fashion-related sites was prepared.
