The Integration of biological databases is critically important because of the interconnectedness of biological research. But it's not easy to integrate these databases for the different formats and designers in heterogeneous environments. So initial design is indispensable to integrate heterogeneous databases. In this paper, after we performed conceptual modeling on a popular nucleotide database, GenBank and a protein database, Swiss-Prot and integrated them by considering cross-reference. we also propose the integration system architecture called Bio-Gateway System, which can help users query closely linked information between two biological databases within one system differently from existing systems as well as query easily on condition that user knows fine condition for less effort.

The olfactory bio technology is largely based on its corresponding recognition technology and smell stimulus that acquires, analyzes, and processes volatile organic compounds present in chemical molecules, which are present in the breath or air evoked by an electronic nose artificially imitating the human biological nose. The olfactory bio technology is also based on a scent display technology that automatically diverges various digital flavors based on aesthetics, concentration, duration, and intensity information required to enhance the sensibility using a computer. Recently, attempts have been made to apply noninvasive screening of dementia by sensing, analyzing, encoding, and transmitting bio information obtained through an olfactory interface, both domestically and externally; further, the olfactory medical content technology has been applied to delay or reduce the onset of dementia. In this study, we will focus on early screening of dementia using olfactory biology information and dementia cognitive enhancer content that delays or reduces the onset of dementia.

BRIS has been established by the Ministry of Agriculture, Food and Rural Affairs since 2011 under Article 21 of the Act on the Preservation, Management and Utilization of Agricultural Life Resources. It is an information service that provides information related to agricultural life resources in connection with the Rural Development Administration, the Forest Service, and Korea Seed & Variety Service, Agricultural Resources and Agricultural and Livestock Quarantine Headquarters. The purpose of this study is to evaluate how the users assess the information system quality (information quality, system quality) for the current Bio Resource Information Service (BRIS). Ultimately, the structural equation modeling analyzes the causal relationship between each variable and how it responds to the user's continuous use intention. As a result, information quality among information system quality and information quality among system quality used as the main variables for the evaluation of BRIS were statistically positively influenced by users' perceived usefulness, while system quality It has been analyzed to have a positive effect on the sustained use intention. The user's continuous use intention is positively influenced by the information system quality and perceived usefulness at a statistically significant level. Especially, the perceived usefulness plays a role in mediating the user's continuous use intention.

U-Healthcare is one of the major applications in ubiquitous sensor network. U-Healthcare has potential to become a critical service for the people who immediately require emergency ambulatory attention. This paper describes about the real time pulse monitoring and reporting system, consisting of two components: thus, the one is a reliable bio-sensor that continuously monitors the pulse information of the subject, and the other is the automatic transfer system that transmits pulse information to both his/her family and hospital care system through the Base Station. In the hospital, this bio-information can be used to treat the patient accordingly. I designed the pulse information monitored by a bio-sensor module that transfers the pulse information to both the Base Station and the central monitoring system through transmitting protocols such as Zigbee and TCP/IP, as well as designed the architecture of information packets for the corresponding protocols. Furthermore, the central monitoring system automatically parses the pulse information of the subject into the web database server, which can continuously provides the real time information and status of the subject via an internet browser to the clients who are family members of the subject and the authenticated medical care personnel as well.

In recent years, the developments of medical technology and emergency medical services have been changed to home from the hospital. In this regard, the researches for the prevention or early diagnosis have become actively. In particular, bio-signal monitoring is applied to a variety of u-healthcare application services. The proposed system in this paper is to provide a security technology to protect the medical information measured from the various sensors. Especially, bio-signal information is privacy-sensitive personal information that must be protected. We applied a two-dimensional code technology, QR code, for the protection and management. In the client side, it can analyze the QR code and confirm the results on devices. Finally, with this proposed platform, we show the results of application service to verify the creation and distribution of integrated image file between the bio-signal and medical image information.

OMIM이나 MedLine과 같은 바이오 정보를 포함한 대규모의 데이터베이스에서의 바이오 정보검색이나 추출은 단계별 처리가 상호적인 운용에 의한 것이 아니라 수동 또는 Perl script에 의한 것이 대부분이다. 바이오정보(bio-information)의 효과적 추출과 유추를 위해서는 현재 상이한 스키마로 이루어진 다양한 데이터베이스들 간의 이질적 데이터(heterogeneous data)를 체계적이고 효율적으로 통합하는 표준 방안이 필요하다. 이를 위해서는 서로 다르게 표현된 다양한 개념간의 관계를 표현하는 지식체계가 필요하다. 본 연구에서는 이러한 지식체계인 온톨로지(ontology)와 자원 메타정보(metadata)를 표현하기 위한 국제적 표준안으로 대두되고 있는 시맨틱 웹(semantic web)에서 제공하는 온톨로지, 메타정보, 스키마 통합 안을 발전적으로 적용하여 이질적 바이오 정보의 효율적 통합처리 방안을 제시하고자 하였다.

Value of rural amenity resources scattered in rural area is difficult to be assessed isolatedly. Rural Amenity Resources Map (RARM) is developed for assessing rural resources based on specific territory. In the developing process, knowledge based system is oriented because rural amenity is differed from personal feeling. Possible decision trees in RARM are developed in reviewing process of previous GIS based decision support systems, and information strategy planning is constructed for achieving goals such as rural tourism, down shifting, and rural investment.

웹을 통해서 수천 또는 심지어는 수백만 명의 정보 수집이 가능해짐에 따라 이러한 사용자들로부터 생성된 데이터를 결합하는 알고리즘을 사용하여 새로운 비즈니스를 창출하는 집단지성이 크게 대두되고 있다. 최근 건강정보에 있어서도 웹을 통하여 사용자들이 정보의 획득이 일반화되면서 웹을 이용하는 사용자의 패턴을 이용하여 식중독이나 독감 같은 공공보건 관련 예후를 예측하는데 사용될 수 있다. 본 논문에서는 인터넷 사용자들의 검색 동향을 통해 독감의 유행을 예측하기 위해 국내외의 인플루엔자 표본감시 데이터 및 검색 동향을 비교하였다. 이러한 사용자들이 독감 관련 검색어의 증가는 실제 독감의 유행과 높은 상관관계(p=0.5, p=0.76)를 보였으며, 이는 인터넷 검색 동향만으로도 초기 단계에서 감시하고자 하는 질병의 발생 양상과 유행 양상의 전개를 예측하는데 중요한 역할을 수행할 수 있음을 의미하는 것으로 인터넷 검색 동향을 통해 공공보건을 예측하는 시스템을 제시한다.

PSPICE modeling of a commercial LED driver IC (TOP245P) and PC817A optocoupler is proposed for the switch-mode power supply (SMPS) (applicable to LED driver) design and simulation. An analog behavioral model of the TOP245P IC including the shunt regulator, under-voltage(UV) detection, over-voltage(OV) shut-down and SR flip-flop is developed by using PSPICE. The empirical equation of PC817A current transfer ratio (CTR) is fitted from the datasheet of PC817A. Two types of SMPSs are simulated with the averaged-model and switching-model. The simulation results by the proposed PSPICE models are in good agreement with those in the data sheet and an experimental data.
