In this paper, we analyze the cycle property of the (n,k)-star graph that has an attention as an alternative interconnection network topology in recent years. Based on the graph-theoretic properties in (n,k)-star graphs, we show the pancyclic property of the graph and also present the corresponding algorithm. Based on the recursive structure of the graph, we present such top-down approach that the resulting cycle can be constructed by applying series of "dimension expansion" operations to a kind of cycles consisting of sub-graphs. This processing naturally leads to such property that the resulting cycles tend to be integrated compactly within some minimal subset of sub-graphs, and also means its applicability of another classes of the disjoint-style cycle problems. This result means not only the graph-theoretic contribution of analyzing the pancyclic property in the underlying graph model but also the parallel processing applications such a as message routing or resource allocation and scheduling in the multi-computer system with the corresponding interconnection network.

In this paper, we present a signal analysis environment with visual programming capability, which is called Signal Analysis and Visualization Environment( SAVE). The system allows a user to perform visually programmed analysis of signals and visualize the results. The visualization facility enables the user to compare original signals with processed ones arid also to display signals overlaid synchronously with the events extracted from the signals. The SAVE system has an extensible architecture: each signal processing algorithm is implemented as a separate building block object module, which can be freely added or removed from the SAVE system without any code modification. We describe the overall structure of the SAVE system and the building block objects, which provide the extensibility in collaboration with together. We illustrate some test runs in order to five a taste of how to use and where to use the system.

New areas can be created by combining separate fields of study. Today, boundaries between fields are collapsing because of rapid progress in technologies, which is also the case in music. In 1969, jazz trumpeter and respected artist Miles Davis combined jazz, rock, and classical music into the fusion genre. Classical music is known to be strict, rigorous, and rigid, and it started to take a different form after experiments with musical crossovers. This study examines the potential of more diverse musical crossovers that musicians use to evolve a new genre. Several musicians in Korea have attempted musical crossovers by following global music trends. In the album, "Love and Peace," the classical music pieces "Flight of the Bumblebee" and Beethoven's "Fate" were arranged using a popular music style.

Formal methods for protocol description of a system is based on the implementation id S/W. However, the importance of H/W implementation for a parts of protocol design is increasing. The combination between H/W and IP technology is needed since the implementation environment is changing from S/W to H/W for implementation of specific application protocol. H/W implementation method starting with formal description procedure is essential to guarantree correctness and reliability of the implemented H/W by characteristic of formal description language. Inthis paper, for an automated H/W implementations, ESTELLE, a formal description method, is adopted. A transformation method from specification of ESTELLE to VHDL is suggested. This is an conceptual method that comparing and analyzing similarities between basic units of protocol description such as computation and communication unit and inter processors in H/W. Then we describe transformation model, and suggest example of transformation from ESTELLE to VHDL with Inres protocol.

This is the Study of the Bass performance of the Jimmy Blanton who is first pioneer of Jazz Style Bass playing. Since the contrabass is using in jazz Performances Before jimmy Blanton, playing technique was mainly played repeatedly with simply two or four Beat with Root or 5th degree of Chord Tone. In Other words, there was only root based Note along with Harmony which doesn't have Bass Solos or Melodic phrase Appeared in Bass playing. Jimmy Blanton Was the First Bass Player who changes This Traditional Concept of Jazz bass playing after New Orleans Jazz era. He was introduced variety of accompaniment Style with Various rhythmic phrase and Bass Soloing like a horn Player. We could know that His Style Continues to Such as Ray Brown, Paul chambers who has a big Name after Jimmy Blanton. I analyzed accompaniment Style and solo techniques Of Jimmy Blanton with the Song "Cotton tail and MR.JB Blues" Which He Performed with Duke Ellington. I learned a lot while I'm analyzing his Performing Style from Jimmy Blanton, such as Target Note playing, using Chord Tones and Arpeggios, Melodic Solo Style, Jazz Style Bowing Technique, Question and Answer Phrasing etc. I could notice That He Was the true Pioneer of the First Bass player In the Early Jazz days.

Phenomenological approach suggests a new dimension in landscape evaluation, which is a contrast to the existing scientific evaluation methods. The characteristics of the phenomenological approach is qualitative, holistic, open, and experiential, whereas that of the scientific approach is quantitative, reductive, closed, and experimental. In phenomenological approach, the average response of a group is not considered as meaningful in landscape evaluation. Instead, the individual response, experience, and feeling are considered as important. In phenomenological approach, people try to see the real world as it is, while scientists tend to simplify the real world in order to handle the complex Phenomena easily. Due to its holistic and qualitative nature, the phenomenological approach has limitations to be a practical landscape evaluation technique. However, recent research demonstrate the possibility of practical phenomenological landscape evaluation technique which is able to satisfy the criteria scientific methods should meet.

Since the IFLA FRBR conceptual model, the transition to a data structure centered on entity-relationships has been underway. Reflecting this international trend, the draft of the 5th edition of the Korean Cataloging Rules (KCR5) were presented in May 2024. This study focused on the 'relationship' which provides additional information to users by connecting one entity with other entities. To this end, (1) the types of relationships between entities defined in the conceptual model and RDA cataloging rule were examined, (2) the actual cases of LC and PCC to record relationships in MARC21 based on RDA were analyzed, and finally (3) practical methods and challenges to be solved for applying them to KORMARC format were suggested. This study mainly utilized RDA training materials and data input guidelines of LC/PCC, and referred to full-MARC bibliographic records and authority records of LC and PCC participating libraries. This study aims to broaden the understanding of the new bibliographic structure and to prepare for the transition to the next-generation bibliographic structure such as BIBFRAME in the future.

일반적으로 태양전지 및 반도체 공정에서 불순물 주입 과정인 도핑(Doping)공정은 크게 몇 가지 방법으로 구분해 볼 수 있다. 소성로(Furnace)를 이용하여 열을 통해 불순물을 웨이퍼 내부로 확산시키는 열확산 방법과 진공 챔버 내부에서 전자기장을 걸어 이온을 극도로 가속시켜 진행하는 이온 주입(Ion implantation)이나 이온 샤워(Ion shower)를 이용한 도핑 방법이 있다. 또한 최근 자외영역 파장의 레이저광을 조사하여 광화학 반응에 의해 도펀트 물질를 분해하는 동시에 조사 부분을 용해하여 불순물을 도포하는 기법인 레이져 도핑(Laser doping) 방법이 개발중이다. 그러나 레이져나 이온 도핑 공정기술은 고가의 복잡한 장비가 필요하여 매출 수익성 및 대량생산에 비효율적이며 이온 주입에 의한 박막의 손상을 치료하기 위한 후속 어닐링(Post-annealing) 과정이 요구되는 단점을 가지고 있고 열확산 도핑 방법은 정량적인 불순물 주입 제어가 어렵고 시간 대비 생산량의 한계가 있다. 반면 대기압 플라즈마로 도핑을 할 경우 기존에 진공개념을 벗어나 공정상에서 보다 저가의 생산을 가능케 할 뿐아니라 멀티 플라즈마 소스 개발로 이어진다면 시간적인 측면에서도 단연 단축시킬 수가 있어 보다 대량 생산 공정에 효과적이다. 따라서 본 연구에서는 새로운 도핑 방법인 대기압 플라즈마를 이용한 도핑 공정기술의 가능성을 제안하고자 도핑 공정 시 웨이퍼 내 전류 패스(Current path)에 대한 메카니즘을 연구하였다. 대기압 플라즈마 방전 시 전류가 웨이퍼 내부에 흐를 때 발생되는 열을 이용하여 도핑이 되는 형식이란 점을 가정하고 이 점에 대한 원리를 증명하고자 실험을 진행하였다. 실험 방식은 그라운드(Ground) 내 웨이퍼의 위치와 웨이퍼 내 방전 위치에 따라 적외선 화상(IR image: Infrared image) 화상을 서로 비교하였다. 적외선 화상은 실험 조건에 따라 화상 내 고온의 표식이 상이하게 변하는 경향성을 나타내었다. 이 고온의 표식이 전류 패스라는 점을 증명하고자 시뮬레이션을 통해 자기장의 전산모사를 한 결과 전류 패스의 수직 방향으로 자기장이 형성이 됨을 확인하였으며 이는 즉 웨이퍼 내부 전류 패스에 따라 도핑이 된다는 사실을 명백히 말해주는 것이며 전류 패스 제어의 가능성과 이에 따라 SE(Selective Emitter) 공정 분야 응용 가능성을 보여준다.

This paper deals with the design and implementation of an interface for interoperation between DiskSim, a well-known disk simulator, and a system-level simulator based on DEVSim++. Such inter-operational simulation aims at evaluation of an overall performance of storage systems which consist of multiple computer nodes with a variety of I/O level specifications. A well-known system-level simulation framework, DEVSim++ environment is based on the DEVS formalism, which provides a sound semantics of modular and hierarchical modeling methodology at the discrete event systems level such as multi-node computer systems. For maintainability we assume that there is no change of the source codes for two heterogeneous simulation engines. Thus, we adopt a notion of simulators interoperation in which there should be a means to synchronize simulation times as well as to exchange messages between simulators. As an interface for such interoperation DiskSimManager is designed and implemented. Various experiments, comparing the results of the standalone DiskSim simulation and the interoperation simulation using the proposed interface of DiskSimManager, proved that DiskSimManager works correctly as an interface for interoperation between DEVSim++ and DiskSim.

Public Service Advertising(PSA) is the integrated marketing concept including strategy and technology in all its aspects that pursue the changes of community to seek an agreement of its members by the intentional and the target oriented way. PSA to the exclusion of commercial intention reflects the current social flow and subject since it is focused to the social issue. PSA plays an important role in creating the further cultural value, and also affects present cultural value to advertising message. In this aspect, this study is very valuable to design the plan for further effective management of advertisement and to analyze communication strategy of PSA. This study is to make dear the nature of PSA by the analysis of contents of visual image and linguistics' factors in actual produced and broadcasted TV advertising, called 'Protection of environment' In the results, PSA related the environment is working to linguistic-centered persuading message corresponding to visual factor, this intends to educate and instruct the consumers in 1980's. PSA, therefore, shows a non-description nature without story line and a hero(heroin) on it. In contrast, after 1990's, PSA was made up image-centered and maximized the effectiveness public campaign through the activating consumer's judgement and intervention. We are able to know that it contributes to considering and persuading the consumer to suggest the story format through the visual way to deliver the message. This study of relationship between visual image and linguistics is a common trend appeared in all media including today's advertising, and may be a remarkable result to present proper direction of PSA campaign.
