Purpose: This study was to explore the structural relationships among instructional practices, family process, academic emotions, self-directed learning, and school happiness perceived by middle school students. Moreover, it examined gender differences in these variables and the mediating effects of academic emotions and self-directed learning on the relationship between instructional practices, family process, and school happiness. Method: This study utilized the data from the 6th year of the Busan Education Longitudinal Study (BELS), and 2,941 middle school 3rd-grade students were selected as the final analysis subjects. Pearson's product-moment correlation coefficients were analyzed to examine the interrelationships among the variables, and independent sample t-tests were conducted to compare gender differences. Structural relationships between variables were analyzed using AMOS 26.0. Results: Firstly, significant positive correlations among instructional practices, family process, academic emotions, self-directed learning, and school happiness were observed. Secondly, there were significant gender differences in the sub-factors of instructional practices, such as teachers' enthusiasm and perceptions of teaching ability, as well as in the sub-factor of academic emotions such as subject interest, self-directed learning, and school happiness. Finally, academic emotions and self-directed learning were found to mediate the relationship between instructional practices, family process, and school happiness. Conclusion: The findings of this study indicated that both family process and instructional practices had a direct impact on enhancing students' school happiness, and also contributed to improving academic attitudes and promoting self-directed learning, ultimately enhancing overall school happiness. These findings can be utilized as valuable empirical data for exploring ways to enhance middle school students' school happiness.

漢語蘇州方言和合肥方言入聲字的比較研究

吳舒雅(Wu, Shu-Ya),李偉(Li, Wei),吳世畯(Oh, Se-Jun) 대한중국학회 2019 중국학 Vol.67 No.-

中國地域廣袤,方言種類繁多,但是,信息科技飛速發展的今天,方言正在悄然流逝,人們 對地方方言和傳統文化漸漸漠視和遺忘,方言的喪失必將導致傳統文化的失根,所以對方言的重視 和保護很重要。作為一名語言文化研究愛好者,希望通過研究比較更多的方言來讓人們更了解自己 的語言。方言作為母語,在我們學習第二語言的時候會直接影響到第二語言的習得,不僅存在積極 的促進作用,也存在消極的阻礙作用,這就需要我們對兩種語言進行深刻的了解和多方面的比較研究。蘇州和合肥分別歸屬於吳語區和江淮官話區,雖然是兩種方言,但是從地理位置上看,相互接連,可見兩種方言之間一定存在一些共同特點和差別。筆者就蘇州和合肥的語言上進行比較研究,選擇展現入聲字的中古音在兩地的今讀,分別從方言的聲母和韻母的對比進行分析和解說,以此來 找出兩種方言之間的差異。 However, with the rapid development of information technology, dialects are slipping away. People are gradually ignoring and forgetting local dialects and traditional culture. The loss of dialects will surely lead to the loss of traditional culture. As a language and culture research enthusiast, I hope to make people know more about their own language by studying and comparing more dialects. As the mother tongue, dialect will directly affect the acquisition of the second language when we learn the second language, which not only has a positive role in promoting, but also has a negative role in hindering, which requires us to have a deep understanding of the two languages and a comprehensive comparative study. Suzhou and Hefei belong to the wu-speaking area and the jianghuai guanhua area respectively. Although they are two dialects, they are connected with each other from the geographical position. It can be seen that there must be some common characteristics and differences between the two dialects. Based on a comparative study of the languages of Suzhou and Hefei, the author chooses to present the modern pronunciation of the Chinese ancient pronunciation of rusheng characters in the two places, and analyzes and explains the differences between the initial and final vowels of the dialects respectively, so as to find out the differences between the two dialects.

Ways of Telicization in Chinese Resultative Compounds

Chenchen Song,Ke Wu 한국생성문법학회 2022 생성문법연구 Vol.32 No.3

In this paper, we build on Song (2018) and undertake a comparative study of the syntactic behavior of verb-resultative (V-R) compounds in three Chinese varieties: Standard Mandarin, Dongying Mandarin, and Wenzhou Wu. They systematically differ from each other in whether they require an obligatory post-V-R morpheme and, if they do, whether the choice of that morpheme is a purely grammatical issue. We find that while both Dongying Mandarin and Wenzhou Wu require a post-V-R morpheme (whereas Standard Mandarin does not), they sharply differ in the choice of said morpheme. We attribute this cross-dialectal variation to the way Chinese varieties telicize their resultative compounds and propose an analysis based on root syntax. After laying out our analysis, which is an extension of the analysis in Song (2018), we further discuss the parameterization of the three-way variation, arguing for a parameter hierarchy-based model over a flat model.

Interleukin-21 (IL-21)+CD4+ T cells are involved in the immune response against hepatitis B virus (HBV) by secreting IL-21. However, the role of IL-21+CD4+ T cells in the immune response against chronic hepatitis C (CHC) virus infection is poorly understood. This study aimed to investigate the role of IL-21+CD4+ T cells in CHC patients and the potential mechanisms. The study subjects in-cluded nineteen CHC patients who were grouped by viral load (low, < 106 RNA copies/ml, n = 8; high, > 106 RNA copies/ml, n = 11). The peripheral frequency of HCV-specific IL-21+CD4+ T cells was higher in the low viral load group and was negatively correlated with the serum HCV RNA viral load in all CHC patients. Meanwhile, IL-21+ cells accumulated in the liver in the low viral load group. In vitro, IL-21 treatment increased the expression of proliferation markers and cytolytic molecules on HCV-specific CD8+ T cells. In summary, these findings suggest that HCV-specific IL-21+CD4+ T cells might contribute to HCV control by rescuing HCV-specific CD8+ T cells in CHC patients.

병렬 테스트를 위한 Exhaustive 테스트 패턴 생성

김우완,김한철 경남대학교 정보통신연구소 1999 연구논문집 Vol.1 No.-

본 논문은 Exhaustive 테스트 방법을 이용 중에 분할 기법을 이용하여 병렬 테스트 가능한 테스트 기법을 제안한다. 제안된 방법은 Exhautive 테스트의 단점인 테스트 수행시간을 줄일 수 있으며, 함수적인 분할 기법을 이용하여 기존 선형적으로 테스트하던 방법을 병렬적으로 테스트할 수 있음을 보여준다. 테스트 패턴 생성을 위해서는 함수 레벨의 기법을 이용하며, 테스트 패턴 생성에는 부울 미분 방법을 사용한다. 또한 이를 이용하여 병렬적으로 삽입할 수 있는 테스트 패턴을 자동적으로 생성하게 된다. In recent years the complexity of digital systems has increased dramatically. Although semiconductor manufacturers try to ensure that their products are reliable, it is almost impossible not to have faults somewhere in a system at any given time. As complexity of circuits increases, more organized and automated methods for test generation become necessary. Up to now, however, most of popular and extensive methods for test generation may be those which sequentially produce an output for an input pattern. They inevitably require a lot of time to search each fault in a system. This paper generates test patterns through the partition method among those using the exhaustive method, and designs and implements a method that can discover faults earlier than other ones proposed ever by inserting a pattern in parallel.

TCP-friendly 혼잡 제어 기법에 관한 연구

김우완,천희식,장상동 慶南大學校 附設 工業技術硏究所 2003 硏究論文集 Vol.21 No.1

멀티캐스트 및 실시간 오디오/비디오 스트리밍 어플리케이션과 같은 새로운 커뮤니케이션 트렌드로 인하여 인터넷상에서 non-TCP 트래픽이 증가하는 추세에 있다. 이러한 어플리케이션은 TCP-friendly기준에 따르는 혼잡 제어를 거의 수행하고 있지도 않으며, 유효 대역폭을 웹 브라우저, FTP, 이메일 클라이언트 등과 같이 TCP를 기반으로 하는 어플리케이션과 공평하게 공유하지도 않는다. 그러므로 지금과 같은 추세로 나아간다면 인터넷은 TCP 트래픽의 Starvation과 Congestion Collapse를 발생시킬 가능성이 높다. 이를 위해 TCP 플로우와의 공존을 지원하는 TCP-friendly프로토콜이 개발되고 있다. 본 논문에서는 TCP friendliness를 위한 현재의 접근 방법을 살펴보고, 각각의 특징을 알아보기로 한다. 그리고 유니캐스트 및 멀티캐스트에 관한 여러 혼잡 제어 프로토콜을 상세히 살펴보기로 한다. Non-TCP traffic on the Internet is on an increasing trend due to new communication patterns such as multicast and real-time audio/video streaming applications. These applications inherently do not perform congestion control in accordance with TCP-friendly standard criteria, nor share valid bandwidth with TCP-based applications like Web Browsers, FTP. E-mail Clients, etc. This means that current drift on the Internet may produce a high possibility of starvation and congestion collapse of TCP traffic. To deal with the unwanted situation such as congestion collapse and starvation, many TCP-friendly protocols supporting non-TCP flows in keeping pace with TCP ones are proposed and still being developed. This paper comprehensively surveys current approaches to TCP-friendliness and their properties in detail in order to systematically aid researches in TCP congestion controls that are the subject of wide attention.

캐싱 알고리즘 동작 확인용 시뮬레이터 설계 및 구현

김우완,천희식 경남대학교 정보통신연구소 1999 연구논문집 Vol.1 No.-

멀티프로세서 시스템을 설계할 경우에는 공유 메모리 구조와 메시지 전달방법이라고 하는 두 가지의 패러다임을 바탕으로 하게 된다. 데이터 분할과 동적 부하 분산 문제를 단순화시킬 수 있으며 확장성을 용이하게 지원하는 장점을 가지고 있는 공유메모리 구조의 멀티프로세서 시스템에서 각 프로세서가 자신의 전용 캐시를 가지는 경우에는 메인 메모리와 이러한 전용 캐시내에 존재하는 데이터 사본간에 일관성 문제가 발생한다. 본 논문에서는 일관성 유지를 위해 제안되어 있는 여러 알고리즘 중 처리 노드와 고대역 저지연 인터커백션 네트워크로 구성되는 공유메모리 구조의 멀티프로세서 프로토타입인 DASH 프로토콜을 지원하기 위한 전용 버스 시스템을 완전 개방형인 IEEE Futurebus+ 스탠다드에 준하여 설계한 다음, 이 시스템이 DASH 프로토콜을 지원하며 캐시의 일관성을 유지하기 위해 필요한 각종 행동과 기존의 범용 버스 시스템이 수행하는 행동의 병렬 처리를 지원한다는 점을 전용 시뮬레이터를 통하여 증명한다. The design of a multi-processor system is based on one of the two approaches: a message-passing mechanism, and a shared-memory architecture[1]. The latter alternative gains an advantage over the former in that it can eliminate problems from the data partitioning and simplify dynamic load balancing so that a system adopting the architecture may be scaled with ease. On the other hand, if a certain shared-memory multiprocessor is allowed to have its own private cache memories, a problem how to keep the consistency between a block in main memory and the copy of the block in a cache shall arise[2][4]. This paper designs and implements a dedicated bus system supporting the DASH protocol, a prototype of a shared-memory multiprocessor consisting of processing nodes and high-bandwidth low-latency interconnection networks, in accordance with the completely open IEEE Futurebus+ Standards. The effectiveness and appropriateness of the bus system are verified through a simulation applied to the DASH protocol. In conclusion, the parallel processing of activities related to cache coherency and those related to existing common bus systems surpass the hardware redundancy induced by the dedicated bus system in performance.

Corona 放電型 靜電氣除去裝置의 製作 및 特性에 對한 硏究

李宇一 慶北大學校 生産技術硏究所 1966 生産技術 Vol.1 No.-

The efficiency of the static electricity elimination from charged materials was investigated with various types of corona gaps. It was found that the needle-line-gap was the most effective type. To prevent high voltage hazard, we can use a capacitance coupled needle-line-gap, which proved still effective. The single-lined needle gap was more effective than the double-lined needle gap. The plastic gap holder is better than the metal gap holder which some what shields the electric field due to the charged body.
