In this study, we propose a integrated type concentrator and compare with the separated type concentrating method, to accommodate 2B+D ISDN basic access traffic. This system's blocking probabilities are analyzed in terms of each class of bit rate, number of output channels, number of subscriber lines, and offered traffic. The result shows that the proposed method can significantly increase the maximum number of subscriber lines connecting to the system via a T1 carrier, compared with that of the "CCITT proposed" multiplexing scheme or the separated type concentrating method.ng method.

This study was executed to give a help in planning and implementing online learning. For this purpose this study investigated the effect of contents presentation types, levels and metacognition on concept map composition and learning process in online learning. Learning contents types were two, meaning-centered or context-centered. Contents levels were divided into two; basic or deficient. Metacognition was divided into two levels according to the scores of scale. Results showed that meaning-centered type(M=45.00, SE=1.97) got better scores in concept map than context-centered(M=34.71, SE=1.98), Presentation levels and metacognition had no significant influence on concept map. There were interaction effect(F=.002, p>.05) between presentation levels and metacogntion levels. The upper group in metacognition got higher score in deficient types whereas the lower group got higher score in basic type. In online learning process, learner's metacognition was an important factor to complement the contents' defect and lack.

The card-based user interface is one of the easiest navigation methods for smart phones, and many of the contents have recently been exposed as cards. In this paper, we have dealt with the definitions of cards and the components of cards used in smart phones. The card can play multimedia including various images and media, and serves as an entry point into detailed contents through the arrangement of buttons or actions. The card UI had different characteristics depending on the type, if it could be classified into basic type, timeline type, workflow type, and dashboard type. The basic type and the timeline type were not suitable for the hierarchy and order of information, and they were suitable for providing large contents. The workflow type was not significantly different from the amount of content, horizontal content arrangement was possible, and the dashboard type was analyzed to be suitable for providing various data as graph or number.

This paper tried an approach of oral literature as the research subject of Soeburi song in Ulsan. First, UlsanSoeburi song is meaningful as materials collected in Ulsan such as Hansil, Dodoekgol, Dudong and Byeongueong. In addition, it is related to regional identity as song native to Ulsan, which has prototype and archetype. And it shows that Ulsan is the city as well as hometown of Soeburi(meaning ' iron manufacture'). The characteristics of lyrics are different between Hansil Soeburi song and Dodeokgol Soeburi song. Jeiman Choi is considered as a good oral literature poet, because he is a performer who is faithful in official structural principal and in original lyrics(archetype) of Soeburi song. Therefore, SoeburiBulmei song of Jeiman Choi signifies aesthetic meaning, having lyrics which make to feel labor's purity and sacred and melody which overcomes labor's difficulty through united action. On the other hand, SoeburiBulmei song of Dalo Kim in Doseokgol shows that he is a extemporaneous performer even though he performs based on official structural principal. In this paper, transmission and changes of UlsanSoeburi song are divided into basic type, frequent shift type and overall type. 'Basic type' originates from Jeiman Choi's Soeburi song in Hansil. 'Frequent shift type' was created by combining SoeburiBulmei song of Dalo Kim in Doseokgol and SoeburiGeumjul song in Ulsan. 'Overall type' is current Soeburi song, which was created by adding Bulmei song for lulling a baby in Byeongueong near Dalcheon region and Seoknyanggan(smithy) Bulmei song. UlsanSoeburi song is being passed down continuously, strengthening the identity as a representative folk song in Ulsan through endless process of transmission and changes.

SOFC가 실제 발전 목적으로 사용되려면 SOFC의 성능 및 수명의 향상과 아울러 발전 목적에 따른 대용량화가 요구된다. 분산형 전원으로 SOFC를 사용하게 될 경우 수백 kW 이상의 발전 용량이 요구되며, 이러한 대형 SOFC 발전 시스템은 수십 ㎾급 SOFC를 기본 단위로 하여 이들을 서로 연결함으로써 구성 가능하다. 평판형 SOFC의 대형화는 기본적으로 개별 전지의 전극 면적을 확대하여 출력 전류를 증가시키고, 단위 전지를 여러 단 적층하여 출력 전압을 증가시킴으로써 가능해 진다. (중략)

필자는 이 논문에서 LA-MORPH 개념에 바탕을 둔 한국어 어형 분석시스템을 구현하기 위한 사전 작업으로서 한국어 동사의 활용 현상을 기술하였다. 한국어 동사 활용의 특징인 동사의 다형성은 크게 두 가지 측면으로 나눠서 관찰할 수 있다. 하나는 동사 및 어미의 변이형 형성과 관련된 측면이고 다른 하나는 이들 동사 및 어미 변이형의 상호 결합에 관련된 측면이다. 관찰의 출발점은 동사가 구체적으로 실현되어 나타나는 단어 형태이다. 규칙 활용 및 불규칙 활용 동사의 실현 형태를 어간 및 어미로 분절하고 이 작업을 통해 얻어진 동사 및 어미의 변이형과 그 기본형 사이에 존재하는 규칙성을 토대로 변이형 유도 모형을 유형별로 제시하였다. 어미를 어간과의 결합 유형에 따라 세 가지로 분류하고 각각에 대해 동사 변이형과의 결합 양상을 제시하였다. 한국어 정서법의 특성을 고려함으로써 동사 활용현상 중 특히 동사 변이형 및 어미 변이형들 간의 결합 양상 및 규칙 등 기존 문법 및 사전이 완전히 기술하지 못하는 부분을 보완할 수 있었다. 더 나아가 'ㄹ' 불규칙 활용, '으' 불규칙 활용 등 기존 문법에서 불규칙적이라고 간주되는 활용 현상에도 일정한 정도의 규칙성이 존재함을 보였다.

In order to performing the joint operation of Korean army efficiently, informations about surveillance, reconnaissance, and situation awareness need to be possessed jointly. In the first development phase (basis type) of the Korean joint tactical data link system (JTDLS-K), essential tactical information and recognized situation are owned among platforms in common by using existing wireless terminals. In the second development phase (completion type) of the JTDLS-K, a JTDLS which can perform network centric warfare (NCW) will be developed in due consideration of technology development of the basis type and common technology maturity degree. This is a joint battlefield system that can show fighting power simultaneous and polysynthetically through providing command and control messages effectively to each platform, which is participating in the joint and combined operations. In this paper, the development of JTDLS-K with a common data processor based on common link integration processing (CLIP) is described. From the test results of the system presented in this paper, it is demonstrated that quadrature phase shift keying (QPSK) signals can be applied to the system.
