자율운항선박 개발은 해운분야의 새로운 발전 동력으로 주목 받고 있으며, 관련 기술개발에 대한 연구가 활발하다. 특히 선박과 육상 간 통신기술 기반의 정보 연결성(connectivity)은 자율운항선박의 실현에 있어 중요한 연구 분야이며, 단위기능 제공에 한정되어 있는 항해 장비 간 통신까지 포함된다. 그러나 수집되는 항해정보들을 체계적으로 분류하고, 이용 및 관리할 수 있는 선내 플랫폼(Platform) 개발에 대한 연구는 미흡하다. 본 연구는 항해장비의 연결성을 향상시키고, 원격운항과 자율운항 선박에 적용될 수 있는 항해정보관리 플랫폼의 기능 및 구조설계와 정보처리에 대한 프로세스 제안을 위한 선행연구로 항해 장비들의 취득정보를 분석하였으며, 응용서비스 및 보안관리에 필요한 정보사항과 기능을 정의하였다. 항해정보관리에 한정 하여 수집되는 정보들에 대해 분석하였으나, 선내 플랫폼 개발의 기초 연구가 될 것이다.

자율운항선박은 제4차 산업혁명 시대의 핵심기술인 사물인터넷과 빅데이터, 인공지능 등이 집약된 미래 고부가가치 선박으로 주목 받고 있으며, 자율운항선박의 도입 및 상용화를 위한 국제적 제도 검토 작업이 활발히 진행되고 있다. 국제해사기구(IMO)는 2017년부터새로운 용어 정립과 함께 기존 협약 규정식별작업(RSE)을 수행했다. 그 결과 기존 협약의 개정과 함께 자율운항선박 운항을 위한 새로운 규정 개발 필요성을 인식하고, 지난해 4월 '자율운항선박 코드(MASS Code)' 개발 로드맵 개발과 함께 세부 기준 개발 작업을 본격화했다. 본 논문에서는 현재 국제해사기구(IMO)에서 개발 중인 자율운항선박 코드를 기반으로 안전한 자율운항선박 운용을 위한 기능요건을 분석하고 세부 기준 및 방향을 제시했다.

본 연구의 목적은 휴대폰이나 무선호출기가 가진 양방향 데이터 전송기술을 활용하여 혈압자료를 주기적 혹은 수시로 송신하고 개인별로 축적된 건강관련데이터를 이용하여 혈압과 관련된 심혈관 질환을 예측하는 시스템을 개발하고자 한다. 본 시스템은 크게 5가지 모듈로 구성되어 있다. 첫째는 가정용 혈압측정기에 무선 데이터 전송 기능이 부가된 혈압측정 및 전송장비이다. 둘째는 무선데이터 송수신을 위한 데이터 전송과 관련된 시스템을 구축하는 부분이다. 셋째는 수신된 개인별 혈압 데이트를 DB화하고 이를 자동으로 검사하여 혈압 이상변동 여부를 수시로 확인하고, 필요시 본인에게 경고 메시지를 보내어서 담당의사와 상의하거나 병원에 가서 정밀진단을 받도록 사전에 건강 이상상태를 경고해 주는 조기경보시스템이다. 넷째는 의사의 전문지식과 개인별 혈압자료를 기초로 하여 인터넷 상에서 스스로 심혈관 관련 질병을 진단해 볼 수 있는 인터넷 기반 심혈관 질병 진단 시스템의 구축이다. 다섯 번째로는 이러한 모든 기능이 복합된 전체 시스템을 통합하고 각 부분을 연결하는 시스템 인터페이스 및 사용자가 아주 쉽게 사용할 수 있도록 하는 사용자 인터페이스 부분이다. 본 논문에서는 이를 위한 전체 시스템의 프레임웍을 제시하고 혈압과 의사의 전문지식에 기초한 심혈관 질병 진단 전문가 시스템에 대하여 구축하고자 한다.

In this paper, we investigate the scheduling algorithm of router system for Internet service based on the qualify-of-service (QoS) level of the input source traffics. We suggest an approprite scheduling algorithm in order to satisfy their QoS requirements for the loss-sensitive traffic and delay-sensitive traffic. For this purpose, we first study the service requirements of the multiplexer in Internet and the definition of QoS based on the ITU-T white recommendations. Second. we suggest a functional architecture of the multiplexer and the scheduling algorithm to satisfy various QoS requirements for Internet service. Finally. the performance measures of interest, namely steady-state packet loss probability and average delay, are discussed by simulation results.

The purpose of this study was to extract and validate the educational goals and the subjects for developing a music gifted curriculum. Based on literature review and analysis of music gifted curricula in foreign countries, 19 educational goals and 18 subjects were derived from literature review and analysis of music gifted curricula in foreign countries. To validate the educational goals and the subjects, delphi survey was carried out twice with 26 expert panelists in the field of music, music education and music gifted education. Delphi survey was analyzed using the mean, content validity ratio, and the degree of consensus. The final set of educational goals for music gifted education included 6 skills related goals, 4 creative expression related goals, 4 knowledge related goals, and 2 attitude related goals. The final set of subjects included 4 major-specific subjects, 5 foundational subjects, 4 theory-related subjects, 3 integration and social participation related subjects. The results of this study can be used as baseline data to develop a music gifted curriculum by providing ideas for deciding what to teach and why to teach in music gifted education.

Objective : The purpose of this study was to investigate the effect of occupational therapy intervention using a fully immersive virtual reality device on the upper extremity function of patients with chronic stroke. Methods : This study used a single subject (ABA) design. The study subjects was a chronic stroke patient with left lateral deviation. Four baseline periods, 12 intervention periods, and 4 baseline regression periods were performed for a total of 20 sessions for 10 weeks. OT intervention with a fully immersive virtual reality device was used every 30 minutes. BBT and WMFT evaluations were performed at each session and the results were displayed in a line graph. Results : The patient's upper limb function has improved. During baseline recurrence, efficacy of treatment was confirmed after removal of intervention, but no significant changes were observed. Conclusion : It has been found that OT intervention with a fully immersive virtual reality device for upper limb function in chronic stroke patients is an effective intervention. However, the effectiveness of maintaining treatment is not important, so we need to develop an easy-to-use home intervention program.

The purpose of the dissertation is to offer basic data available for being conducive to application of a training program by comparatively analyzing the players' physical strength, the knee joint, a hip joint, power of the trunk joint and muscle power in order to study isokinetic strength and muscle power between short distance athletes and Taekwondo players. This study measured peak power, %Body weight peak power, always power, and %Body weight peak power targeting 8 male athletes and 8 male Taekwondo players who warmed up 10 minutes before from the test to reduce repulsion and unfamiliarity at the instrument. The power of the knee joint($60^{\circ}$/sec), muscle power($180^{\circ}$/sec), were measured by using HUNOM(U.S.A). As a result of the physical strength, statistically, short distance athletes were indicated to be better in muscle strength, muscular endurance than Taekwondo players, and there was no significant difference between flexibility, power, and muscular endurance. Although the short distance athletes were indicated to be better in right and left muscle strength of knee joint than Taekwondo player, there was no significant difference and Taekwonde players were indicated to be higher at the right and left muscle power than short distance athletes.

The number of industrial structures that must be demolished due to functional and structural deterioration has been increased. There is an increasing application of explosive demolition or explosive demolition combined with mechanical demolition to minimize temporal and spatial environmental hazardous factors created during the process of demolition. In this case study, to demolish the turbine foundation structure, which is a large-section reinforced concrete structure, the parital explosive demolition thchnique was conducted. As a result of the partial explosive demolition, the overall crushing of the blasting sections of beam-column joints structure with haunched beams and second-floor columns about the turbine foundation was satifactory, and the explosive demolition was completed without causing any damage to surrounding facilities.

This article is researched to analyze what kinds of projects were conducted by the special grant, the balanced development special account(BSDA), and the municipal projects in the case of Sangjucity and Seochengun, in the introduction time of the bock grants of BSDA and the municipal development plan in 2010. Furthermore this study presents the problems and the direction of improvement. For the territorial integration of a regional development in long-term, I suggest that the spacial grant and BSDA are necessary to be integrated because of ambiguous difference. And also the block grants of current 24 projects in 7 groups should be reclassified as the concept and the functional feature of pluralistic rural development.
