Various design schemes for network using wireless sensor nodes have been widely studied on the several application areas ranging from the real world information collection to environmental monitor. Currently, the schemes are focused on the design of sensor network for low power consumption, power-aware routing protocol, micro miniature operating system and sensor network middleware. The indoor localization system that identifies the location of the distributed nodes in a wireless sensor network requires features dealing with mobility, plurality and other environmental constraints of a sensor node. In this paper, we present an efficient location system to cope with mobility of multiple mobile nodes by designing a location handler that processes location information selectively depending on the nodes' density in a specific region. In order to resolve plurality of multiple mobile nodes, a routing method for the location system is also proposed to avoid the occurrence of overlapped location data.

본 연구의 목적은 인포메이션 아키텍처(IA)의 원칙에 근거하여 웹 사이트를 평가할 수 있는 정성적 및 정량적 기준을 설정하고, 이 기준을 이용하여 한국 대학사이트를 종합 평가함으로써 대학사이트 설계에 적용될 수 있는 일반적인 기본원칙을 제시하는데 있다. 이 연구에 IA 수업을 수강하고 있는 학생들이 직접 참여하여 컨덴츠조직, 네비게이션시스템 레이블링시스템 검색시스템에 대한 평가기준 및 항목들을 설정하였다. 또한 그들이 피실험자로서 이 기준을 활용하여 무작위를 추출된 27개 대학사이트에 대한 정량적 평가를 하였다. 정성적으로 상세히 분석한 대학사이트의 문제점들은 히 네 범주(컨텐츠조직, 네비게이션. 레이블링, 검색)로 구분하여 기술되었다. 이 분석결과를 토대로 체계적인 컨텐츠조직, 유연성있는 네비게이션시스템, 일관성있는 레이블링시스템, 효율적인 검색시스템을 구축하기 위해서, 대학사이트의 설계에 고려해야 할 일반적인 원칙을 제시하였다.

Analyzed are recent advances in design of novel boronared conjugates of synthetic and natural porphyrins and chlorins. These compounds showed high efficacy as cytotoxic agents for tumor cells in culture and as phototoxins in photodynamic therapy of tumor xenografts. Thus, boronated porphyrins and chlorins emerge as promising class of anticancer agents with potentially multiple advantages: the chemotherapeutic drugs alone and photo- and radiosensitizers in binary treatments.

Nutrition information about food is written on the label paper, which is very inconvenient for visually impaired people to recognize. In order to solve the inconvenience of visually impaired people with nutritional information recognition, this paper proposes a product nutrition information guide system for visually impaired people. In the proposed system, user's image data input through UI, and object recognition is carried out through YOLO v5. The proposed system is a system that provides voice guidance on the names and nutrition information of recognized products. This paper constructs a new dataset that augments the 319 classes of canned/late-night snack product image data using rotate matrix techniques, pepper noise, and salt noise techniques. The proposed system compared and analyzed the performance of YOLO v5n, YOLO v5m, and YOLO v5l models through hyperparameter tuning and learned the dataset built with YOLO v5n models. This paper compares and analyzes the performance of the proposed system with that of previous studies.

Advanced countries have mandated applying BIM in construction projects. Also, Public Procurement Service has planned to mandate applying BIM to all construction project that ordered in PPS from 2016 in KOREA. However, now Seumter that is building administration system is not supported BIM based construction license BIM information from Seumter. Thus, despite the applicant is preparing a BIM model, they do not take advantage of BIM information in Seumter. In previous studies. We developed a BIM based building approval submission system. In this study, we verified the system that developed in previous research. As a result, requirement information input time reduction in Seumter system showed high satisfaction. But there was as low usability because building approval submission system cannot support some information for building approval in seumter. If the system will do utilization and management with the building approval system, the applicant can be using BIM base design document information and saving the time that takes at building approval submission. Study about the system improvement is required for application to building approval system.

Cross-domain event information sharing is a topic of great interest in the area of event based network management. In this work we use data sets which represent actual attacks in the operational Internet. We analyze the data sets to understand the dynamics of the attacks and then go onto show the effectiveness of sharing incident related information to contain these attacks. We describe universal data acquisition system for event based management (UniDAS), a novel system for secure and automated cross-domain event information sharing. The system uses a generic, structured data format based on a standardized incident object description and exchange format (IODEF). IODEF is an XML-based extensible data format for security incident information exchange. We propose a simple and effective security model for IODEF and apply it to the secure and automated generic event information sharing system UniDAS. We present the system we have developed and evaluate its effectiveness.

This paper presents a dynamic development of an ontology-based statistical information system supporting the collection, storage, processing, analysis, and the presentation of statistical knowledge at the national scale. To accomplish this, we propose a data mining technique to dynamically collect data relating to citizens from publicly available data sources; the collected data will then be structured, classified, categorized, and integrated into an ontology. Moreover, an intelligent platform is proposed in order to generate quantitative and qualitative statistical information based on the knowledge stored in the ontology. The main aims of our proposed system are to digitize administrative tasks and to provide reliable statistical information to governmental, economic, and social actors. The authorities will use the ontology-based statistical information system for strategic decision-making as it easily collects, produces, analyzes, and provides both quantitative and qualitative knowledge that will help to improve the administration and management of national political, social, and economic life.

This study perceived that there are limits to prompt and accurate monitoring when an accident occurs and the correct information of egg production stage, such as the date of spawning, cleaning, and refrigerating cannot be identified, since eggshell codes using barcode only show numbers identifying a city and province and the name of producers. To fix this problem, this study partially suggested the RFID (Radio Frequency Identification) technology and IoT-based Connected System. The proposed system in this study shares data with related agencies as the system of agricultural and livestock product information runs as the main server, and the database information of the proposed system is provided by farmhouses, distributors, and sellers. Through various media such as a webpage or mobile application built to provide the relevant information, customers can search and obtain information about agricultural and livestock products they want. Since the information on an entire process is open to the public, information ranging from simple to clear, additional ones such as hazardous elements can be viewed.
