The speech synthesis technology is widely used and its application area is also being broadened to an automatic response service, a learning system for handicapped person, etc. However, the sound quality of the speech synthesizer has not yet reached to the satisfactory level of users. To make a synthesized speech, the existing synthesizer generates rhythms only by the interval information such as space and comma or by several punctuation marks such as a question mark and an exclamation mark so that it is not easy to generate natural rhythms of people even though it is based on mass speech database. To make up for the problem, there is a way to select rhythms after processing language from a higher level information. This paper proposes a method for generating tags for controling rhythms by analyzing the meaning of sentence with speech situation information. We use the Systemic Functional Grammar (SFG) [4] which analyzes the meaning of sentence with speech situation information considering the sentence prior to the given one, the situation of a conversation, the relationship among people in the conversation, etc. In this study, we generate Semantic Speech Control Tag (SSCT) by the result of SFG's meaning analysis and the voice wave analysis.

장문수 한국미래교육학회 2015 미래교육연구 Vol.5 No.1

요즘에 청소년들이 즐기는 음악과 학교에서 배우는 음악이 서로 분리되어 있으며 사춘기적인 수줍음과 변성기로 인해 음악 수업시간에 잘 참여하지 않으려는 현실에서 흥미와 참여를 유도하기 위해 우쿨렐레라는 악기를 선택하여 PBL모둠별 활동으로 진행하였다. 악기 특성상 1대 1 지도의 해결책으로 모둠별 전문가 이끔이 방식을 적극 활용하였으며 음악 수업시간에만 한정하지 않고 학급음악회, 교내음악경연대회, 점심시간을 이용한 틈새아르떼 공연, 지역주민과 같이 하는 교외 밖 틈새아르떼 공연 등 다양한 음악활동으로 음악수업에 흥미를 유발하는 계기가 되었고, 모둠원간의 활동으로 소통과 배려하는 마음과 교우관계가 돈독해 지고 있음을 알 수 있었으며, 발표할 수 있는 경험이 쌓이면서 자신감 상승으로 자아효능감을 신장시키게 되었다. Today, music enjoyed by teenagers has a gap from music they learn at school. To induce interest and participation in reality in which they are reluctant to participate in music classes due to their adolescent shyness and mutation, this study selected ukulele as an instrument to conduct various group activities for problem-based learning (PBL). This study adopted the method of recruiting experts to lead each group as a solution to one-on-one guidance. Without limiting the activities to music classes only, various music activities were conducted to arouse interest in music classes such as class concerts, in-school music contests, lunch-hour performances, and extracurricular performances with local residents. Cooperative activities among group members also promoted communication, care and peer relations. As students acquired experience in recitals, their confidence increased, thereby enhancing their self-efficacy as well.

장문수,김유두 한국실천공학교육학회 2018 실천공학교육논문지 Vol.10 No.2

통신망을 이루는 주요 구간 중에 전송망에 해당하는 네트워크 구간에 대하여 소프트웨어 정의 네트워크 제어 기술은 네트워크 산업에 걸쳐 네트워크 운용 및 프로비저닝을 활용한 네트워크 제어 환경의 변화로 자리 잡아가고 있다. 현재 PTN 장비의 보급화와 함께 개발을 추진하고 있으며 프로비저닝을 위한 구성을 단계적으로 수행하고 있다. 실제 상용망의 PTN 장비를 주축으로 프로비저닝을 구성하면서 SDN기반 제어 시스템 구축을 적극적으로 도입하고 있다. 따라서 본 논문에서는 PTN을 주축으로하는 패킷 기반 전송망에서의 SDN 시스템에 대한 내용과 동향을 살펴보고 SDN을 구성하기 위한 오픈소스인 OpenDaylight에대한 연구를 통해 실제 상용망에서 활용하고자 하는 핵심 기술에 대해서 연구한다. 그리고 운영자들을 대상으로 운영 교육 모델에 필요한 소프트웨어 정의 제어 기술에 대해 연구한다. During the major sections of the network, Software-defined network control technology for the network area corresponding to the transmission network is becoming a change in network-controlled environments utilizing network operation and provisioning across the network industry. Currently development is underway along with the deployment of PTN equipment and configuration for provisioning is being phased out. It is actively introducing establishment of SDN-based control system while constructing provisioning of PTN equipment from actual commercial network. Therefore, in this thesis, we are going to look at the contents and trends of SDN systems in packet-based transmission networks based on PTN and use them in research on OpenDaylight, an open source for configuring SDN. It then Network Operator will study the software defined control techniques for operational education.

82 dental students were divided into 7 groups, and each group used one of the mouthrinses which formulations were 5% sucrose, 0.1% NaF, 3% NaCl, and their combinations. Subjects refrained from toothbrushing and rinsed their mouths twice a day, after waking up and before going to bed, for two days. The degree of plaque attachment was measured by Patient Hygiene Performance Index(PHP) and Simplified Oral Hygiene Index(OHI-S). The plaque was disclosed by erythrosin tablets and pretreatment measurement was done. Then, plaque was removed by thorough toothbrushing. After two days of mouthrinsing, plaque was disclosed and measured by the same method. In all groups, plaque attachment increased over the initial level. There was no significant difference between groups by ANOVA. Ranks were given to each mean of groups, and the effect of mouthrinses were compared with each other by the ranks. Combination of salt and fluoride had greater inhibitory effect on dental plaque formation than fluoride alone. Combination of salt and sucrose had greater facilitating effect on dental plaque formation than sucrose alone.

제어시스템은 원격지의 시스템을 효율적으로 감시하고, 관리하는 목적으로 사용되는 시스템이다. 초창기의 제어시스템은 특정 용도에 맞게 개별적으로 설치되어 운영되었으나, 1990년대 이후에는 시스템의 유지관리 및 다른 시스템과의 상호운용의 요구로 점차 개방형 시스템으로 변하기 시작하면서 보안의 위험에 노출되기 시작하였다. 제어시스템은 전력, 가스, 상하수도, 교통 등의 국가주요시설의 운용에 사용되고 있으며, 해당 시스템에 사이버 침해사고 발생 시 국가적 혼란을 야기 시킬 수 있으므로 특별한 보안관리가 요구된다. 본 논문에서는 국외 제어시스템 관련 보안제품들의 기술동향을 분석하고, 이들 제품들의 특성을 비교하며, 제어시스템 전용 보안기술 개발에 필요한 기술요구사항들을 제시하고자 한다. Industrial control system is the one that is used by the purpose of watching and managing remote systems efficiently. The early industrial control system is established and operated individually, focusing on specification usage. Since 1990's, industrial control system has begun to be expose to the danger of security because it began to be transmitted into open system gradually by request of its managing system and running with different systems together. Industrial control system has been used in running the main faculty of countries such as electric power, gas, water supply and drainage, traffic systems etc. In case cyber infringement accident happens to industrial control system, national confusion will be caused, so industrial control system is required to be managed with security. In this paper, We have analyzed technological trend of Security products on industrial control systems used in overseas, compared among features of these products and are finally going to present technological requirements that is needed to develop security technology in the exclusive use of industrial control systems.

The purpose of this study was to evaluate the validity of new caries activity test which used pH 5.4, 30% sucrose liquid medium. The caries experience and caries activity of 220 second grade elementary school children were examined. Caries experience was measured by dt, ft, dft, DT, FT, DFT, dDT, fFT and dDfFT indexes. Caries activity was measured by the pH drop of the pH 5.4, 30% surcrose liquid medium which was inoculated by dental plaque and incubated for 4 days. Dental plaque was sampled from the subject's upper buccal toothsurfaces by a cotton applicator and the latter was directly put into the test tube containing the medium. Every 24 hours pH was read by observing the color change of pH indicator bromcresol green in the medium with the color standard. 3 or 4 days' pHs were converted to scores and then added together. There was significant correlatation between caries experience and caries activity test score. Pearson' s correlation coefficient between dDfFT index and the sum of caries activity test scores for 96 hours was 0.4186(P=0.0000). High caries activity group(pH<5.0) had 2-3 or 1.5-2-fold more dDfFTs than low caries activity group (pH≥5.0). Therefore, the new caries activity test which uses pH 5.4, 30% sucrose liquid medium may be used to differentiate the high caries activity group which need intensive caries prevention from the low caries activity group as a valid and practical caries activity test.

DNP3 제어시스템 프로토콜 취약점 실험

장문수,이건희,김신규,민병길,김우년,서정택 보안공학연구지원센터 2010 보안공학연구논문지 Vol.7 No.1

제어시스템은 원격지의 시스템을 효율적으로 감시하고, 관리하는 목적으로 사용되는 시스템으로, 전력, 가스, 상하수도, 교통 등의 국가주요시설의 운용에 사용되고 있다. 비공개 제어시스템 프로토콜 표준이 점차 국제 표준으로 공개됨에 따라, 공개된 표준은 공격자에게 제어시스템 및 네트워크 동작에 대한 더 많은 지식을 제공하게 되었으며, 점차적으로 제어시스템에 대한 사이버침해의 가능성과 위험성이 높아지고 있다. 제어시스템에 사이버 침해사고 발생 시 국가적 혼란을 야기 시킬 수 있으므로 특별한 보안관리가 요구된다. 본 논문에서는 DNP3 제어시스템 프로토콜 보안 취약점 및 취약점을 이용한 공격을 분석하고, 실험망을 구성하여 해당 취약점 존재 유무에 대한 실험을 수행 한다.
