To investigate the effects of haunch repair on the system seismic performance of steel moment-resisting frames (steel MRFs), a case study was conducted for a 13-story frame damaged during the 1994 Northridge earthquake. It was assumed that only those locations with reported damage would be repaired with haunches. A new analytical modeling technique for the dual panel zone developed by the author was incorporated in the analysis. Both the inelastic static and dynamic analyses did not indicate detrimental side effects resulting from the repair. As a result of the increased strength in dual panel zones, yielding in these locations were eliminated and larger plastic rotation demand occurred in the beams next to the shallow end of the haunches. Nevertheless, the beam plastic rotation demand produced by the Sylmar record of 1994 Northridge earthquake was still limited to 1.7% radians. The repair resulted in a minor increase in earthquake energy input. In the original structure, the panel zones should dissipate about 80%(for the Oxnard record) and 70%(for the Sylmar record) of the absorbed energy, assuming no brittle failure of moment connections. After repair, the energy dissipated in the panel zones and beams were about equal.

In Korean Building Code 2005(KBC-2005), the Seismic Zone Factor is regulated by separating the seismic zone into two part. This seismic zone factor is not matched to regional seismic characteristics of our country because the factor is based on International Building Code 2000 (IBC-2000) of USA. This study inquiry for having a sufficient grasp of the seismic characteristics of south Korea region and appling for the seismic cope plan. We have collected and analyzed earthquake record happened in domestic region. There are two kinds of earthquake record. One is Historical earthquake data, another is Instrumental earthquake data. I used Instrumental earthquake record data which reliance is higher than historical earthquake data for proposing attenuation formulas by analyzing a correlation the epicenter and the distance.

This paper is propose for some guidelines in making curriculum for the training of archivists for Koran records. This paper pays special attention to the revival of the culture of record-keeping tradition of our owns. Without it's revival, a blind introduction of archival sciences based on Western civilizations can be ended up another version of cultural and academic imperialism as such in the field of the record-management of Korean records. Rapidly growing information and computer technology of our owns must be incorporated in the making of archivist training programs. It proposes that the opening of archival science major as a department at the graduate school level is in the long run essential, yet that of an associate master degree program can be in real an alternative. A training of archivists is not just to produce of a technician but a crafts(wo)man who would be in the vanguard of the renaissance of the record-keeping culture in Korea.

40 species of the family Caprellidae Leach, 1814 are recorded in Korean waters. Caprella aino Utinomi, 1943 was newly collected from seaweed farms from the southeastern waters of Korea. C. aino was firstly reported in Japanese waters in 1943. Adults of C. aino and Caprella mutica Schurin, 1935 are easily distinguished in that C. aino have pereonite II and gnathopod II without setae and two small tubercles of articulation of gills in pereonite III-IV, while C. mutica do pereonite II and gnathopod II covered with setae and those of pereonites III-VII with many tubercles. However, subadult C. mutica is hardly distinguishable from C. aino in that tubercles of pereonite III are less developed and they have inconspicuous setae of pereonite II and gnathopod II. Nevertheless, C. aino is distinguished from subadult C. mutica because adult C. aino have dorsal tubercles on pereonite IV, V, VI, VII unlike that of C. mutica. We report C. aino as a new record in Korean water with comparison of C. mutica.

임베디드 시스템이 소형화되면서도 많은 기능들이 요구됨에 따라 여기에 올라가는 임베디드 소프트웨어 역시 점점 복잡해지고 있다. 특히 멀티 쓰레드 환경에서 수행되는 임베디드 소프트웨어의 경우, 실행도중 오류가 발생했을 때 버그의 원인을 찾기가 어려울 뿐 아니라, 버그를 재현하는 것 또한 쉽지 않다. 효과적인 디버깅을 하기 위해서는 프로그램 실행 중에 버그가 발생했던 상황을 그대로 재현해야 한다. 본 논문에서는 프로그램이 실행하는 도중에 이벤트가 발생하는 시점의 이벤트 정보를 record 하고, 나중에 이를 이용하여 버그가 발생한 시점으로 replay 할 수 있는 기법을 개발하였다. VPOS[1]에 이 기법을 적용함으로써 임베디드 소프트웨어의 결함을 좀더 쉽게 탐지하여 효율적인 디버깅이 가능하도록 하였다.

With the advance of Information Technology (IT) and dynamic requirements, diverse application services have been provided for end users. With huge volume of these services and information, users are required to acquire customized services that provide personalized information and decision at particular extent of time. The case is more appealing in healthcare, where patients wish to have access to their medical record where they have control and provided with recommendation on the medical information. PHR (Personal Health Record) is most prevailing initiative that gives secure access on patient record at anytime and anywhere. PHR should also incorporate decision support to help patients in self-management of their diseases. Available PHR system incorporates basic recommendations based on patient routine data. We have proposed decision support service called "Smart CDSS" that provides recommendations on PHR data for diabetic patients. Smart CDSS follows HL7 vMR (Virtual Medical Record) to help in integration with diverse application including PHR. PHR shares patient data with Smart CDSS through standard interfaces that pass through Adaptability Engine (AE). AE transforms the PHR CCR/CCD (Continuity of Care Record/Document) into standard HL7 vMR format. Smart CDSS produces recommendation on PHR datasets based on diabetic knowledge base represented in shareable HL7 Arden Syntax format. The Smart CDSS service is deployed on public cloud over MS Azure environment and PHR is maintaining on private cloud. The system has been evaluated for recommendation for 100 diabetic patients from Saint's Mary Hospital. The recommendations were compared with physicians' guidelines which complement the self-management of the patient.

One of the reasons behind the surfacing of such issues is because the record does not exist and even if the records remained, it is because they are not being properly managed. In Korea, National institutions in the field of visual arts, currently there are no archives that manage only the records for the visual arts as an independent institution, and the reality is that the National Museum of Archives is still in the beginning stage as well. This study has conducted a research on the records collection strategy and the management of the record information of an author who is the creator of the visual arts as a starting point of the visual arts. For this purpose, the definition of visual arts and the concept of an author covered in this study will be examined and the types of documentary that may occur in the field of visual arts were analyzed. In addition, the history of an author is its personal record thus a personal history and private archive have been examined. Based on this background, the cases on the personal record and the management of the record information of domestic and foreign authors were analyzed and the implications were derived.

In introducing memory methods in various educational fields, programs in a mobile environment can be used for the purpose of increasing accessibility and enhancing the effectiveness of education. It is much easier to remember words with meaning than to remember numerical information such as years. From the standpoint of increasing the educational effect, the part that needs to be supplemented with the help of the application can be said to be numerical information. Most studies related to conventional numerical memory have focused on the form that helps memory by imaging numbers. In the paper on memory-based meta-record algorithms in the mobile environment, the application developed in the previous study attempts to supplement this by discovering and simply modifying the user's mistakes in the entered numerical information. In this study, we aim to increase the memory rate by constructing metadata based on personalized log information and correcting mistakes. To do this, applications suitable for the mobile environment are developed, a structure of meta-record data is proposed, and meta-record application algorithms are implemented and evaluated.

In a situation where drone-related crimes continue to rise, research in drone forensics becomes crucial for preventing and responding to incidents involving drones. Conducting forensic analysis on flight record files stored internally is essential for investigating illegal activities. However, analyzing flight record files generated through the exclusive DUML protocol requires a deep understanding of the protocol's structure and characteristics. Additionally, a forensic analysis tool capable of handling cryptographic payloads and analyzing various drone models is imperative. Therefore, this study presents the methods and characteristics of flight record files generated by drones. It also explains the structure of the flight record file and the features of the DUML packet. Ultimately, we conduct forensic analysis based on the presented structure of the DUML packet and propose an extension forensic analysis system that operates more universally than existing tools, performing expanded syntactic analysis.
