The purpose of this paper is to analyze storytelling in on-line personal game broadcasting in order to find out unique characteristics of on-line personal game broadcasting. This study selects Youtube channel and as classic cases of on-line personal game broadcasting, and analyzes the cases with Bakhtin's theory of carnival. The on-line personal game broadcasting modifies the broadcasting format of mass media externally. Also, the on-line personal game broadcasting internally moves between interior and exterior of the game text in order to create new narrative events. In this process, the polyphonic utterances of the broadcasting host appeared. The reversal of the tragedy and the comedy leads the audience to catharsis.

Recently, many countries around the world including Korea (Rep. of) have actively introduced online voting using distributed ledger technology (e.g. blockchain). However, online voting using distributed ledger technology based on the widely deployed telecommunication/ICT infrastructure. There is insufficient analysis of potential security threats. In this paper, we suggest a model for online voting system using distributed ledger technology and propose countermeasures by analyzing the security threats that may occur in online voting process in terms of information security.

전 세계 곳곳에서 매년 발생하고 있는 홍수, 가뭄, 수질 문제는 인류가 해결해야 할 공통적인 문제이다. 홍수, 가뭄, 수질 문제뿐만 아니라 수자원의 지역적인 불균형과 인근 지역의 물 분배 문제, 공유하천 문제 등으로 인한 물 사용자 간의 물 갈등, 물 분쟁도 지속되고 있다. 최근 정보통신기술이 발달함에 따라 수자원 관련 각종 위험지표, 물 갈등, 물 분쟁 사례를 자료화하여 활용할 수 있는 온라인 플랫폼이 개발되고 있다. Aqueduct 3.0은 전 세계 물 위험을 식별하고 평가할 수 있는 물 위험평가 프로그램(water risk assessment tool)으로 세계 수자원 협회에서 2019년 기존 프로그램을 업데이트하여, 온라인 플랫폼을 통해 전 세계 각국의 지역별 수자원 분포에 따른 각종 위험지도와 데이터를 무료로 제공하고 있다. 또한 세계 자연기금(World Wide Fund For Nature)도 온라인 플랫폼으로 전 세계의 물 위험 필터도구(water risk filter tool)를 제공하고 있다. 또한 물 갈등 연대기(Water Conflict Chronology)는 태평양 협회에서 전 세계 물갈등 사례를 수집하여 연대별로 정리한 것으로, 업데이트되어 2022년 사례까지 제공하고 있다. 본 연구는 Aqueduct와 Water Conflict Chronology 등 온라인 플랫폼에 탑재된 한반도 관련 수자원 자료를 조사하여 기존 자료와 분석하였다. 연구 결과 Aqueduct와 Water Conflict Chronology 등 온라인 플랫폼이 수자원 관련 교육의 유용한 도구임을 알 수 있었다.

With Covid-19, the era of Untact has arrived. Online is bound to develop because face-to-face has become difficult among the threats of the Corona virus. Even in this era, even worship services to God have been offered online. Teenagers, the generation most accustomed to online, seem to easily adapt to online worship. Online youth worship is expected to continue even in the post-corona era. If so, the theological reflection on whether online youth worship is possible is necessary. Through theological reflection, we need to secure theological justification for online youth worship, and strive to make it a better and more accurate online worship service. Online worship tailored to the eye level of youth and online worship that meets the spiritual needs of youth should be planned, prepared, and implemented. This paper presented the theological justification for online youth worship by looking at the definition of worship, elements of worship, places of worship, and history of worship. In addition, while examining the characteristics of adolescence, it suggested why online youth worship is important and necessary. Then, in order to plan online youth worship that is more advanced and more accurate than the online worship currently being conducted in each church, the reality of online youth worship was presented by examining the purposes, contents, and methods of online youth worship.

21세기는 지식 정보화 시대라고 말하며 정보 통신혁명은 모든 매체에서 인터넷을 연결시키면서 우리의 생활 및 사고에 대한 패러다임의 변화를 가져 왔다고 할 수 있다. 따라서 본 연구에서는 미래사회를 대비해야 할 우리 어린이들에게 정보화의 발전과 주5일제 수업으로 더욱 활발해진 개별학습 기회가 혹시나 의미 없는 시간소비를 통해 사이버 폭력 및 사이버범죄 등 정보화(인터넷)의 역기능에 노출 될 위험성이 있다고 볼 수 있다. 이에 정보통신 윤리교육을 강화하여 인터넷의 역기능을 차단하고 창의적이고 탐구적인 학습활동에 흥미를 가지고 적극적으로 참여 할 수 있도록 다음과 같이 운영한다. 첫째, 학생 중심의 자치적인 온라인 커뮤니티 활동을 통해 학생중심의 게시판을 개발 적용한 후 게시판별 분석자료를 통해 학생 이해 및 소질과 적성을 발굴 지도한다. 둘째, 분석자료 내용을 누가 기록하고 그 내용을 가공, 적용하여 또래집단의 원활한 교우관계 조성과 성장발달을 도모하고 여가시간을 효율적으로 활용하는 능력을 길러 궁극적으로 자아실현과 새로운 가치창조의 기호가 되도록 지도하는데 연구의 목적을 두고자 한다.

스토리지 스냅샷은 특정한 시점의 스토리지 시스템의 이미지를 말하며, 데이터의 보호 및 유지를 위한 필수적인 기술이다. 스냅샷 구현을 위해서는 블록 수준, 파일 시스템 수준, 하드웨어 수준으로 구현이되지만, 파일 시스템 캐시에 대한 처리 등으로 인해 스냅샷 일관성이 깨지거나, 하드웨어 혹은 파일시스템에 종속적이여서 여러 파일시스템과 하드웨어에 일관적인 스냅샷을 제공할 수가 없다. 또한, 대부분의 스냅샷들은 정적 스냅샷을 제공하여, 스냅샷 생성시간 동안 시스템의 서비스를 멈춰야 한다. 본 논문에서는 파일시스템과 하드웨어에 독립적이면서, 온라인 스냅샷 방법을 제안한다.

This paper was to figure out why online wine purchasing is not activated despite of the many advantages of having online transactions and to fine key determinants of online wine purchasing intention. Thus, the purpose of this study was to identify the determinants of online wine purchase intention, and examines the relationships between the determinants and online wine purchase intention. Data was collected from those who have experienced in using online wine store to purchase wine, and data was used to test the proposed research model. The findings showed that perceived usefulness and social influence(subjective norm, image) were key determinants of online wine site trust, but they were not related to online wine site trust. It also was found that perceived usefulness, perceived ease of use and subjective norm were positively and significantly related to online wine purchase intention whereas it had no relationship with image. In addition, online wine site trust was shown to influence on online wine purchase intention. Finally, the mediating effects were found in the relationships between perceived usefulness, subjective norm, and online wine purchase intention. Based on the results of the study, implications for future research are drawn.

In this paper, we propose an efficient dynamic workload balancing strategy which improves the performance of high-performance computing system. The key idea of this dynamic workload balancing strategy is to minimize execution time of each job and to maximize the system throughput by effectively using system resource such as CPU, memory. Also, this strategy dynamically allocates job by considering demanded memory size of executing job and workload status of each node. If an overload node occurs due to allocated job, the proposed scheme migrates job, executing in overload nodes, to another free nodes and reduces the waiting time and execution time of job by balancing workload of each node. Through simulation, we show that the proposed dynamic workload balancing strategy based on CPU, memory improves the performance of high-performance computing system compared to previous strategies.

This study is based on the previous research which proved that "seeking convenience", "seeking low-cost" and "pleasures of shopping" are the major shopping motivation of online shopping. Research is conducted by using the trust as mediator, purchase intention as dependent variable. Also, differences between Chinese and Vietnamese consumers are applied in analysis of the model. The results were as follows: First, "seeking low-cost" and "pleasures of shopping" have positive effects on trust. Second, all shopping motivation have positive effect on purchase intention. Third, the trust has positive effect on purchase intention. Fourth, consumers' shopping motivation have significant difference in trust and purchase intention according to Chinese and Vietnamese consumers. The results of this study presented the strategic implications for operators at online shopping area.
