초.중등학교에서 활용중인 종합정보관리 시스템 중에서 학교급식 관리시스템은 교육청 단위로의 DB 통합과 전국단위 교육행정정보시스템의 구축, 현장 적합도와 사용자 편이성 미흡 등의 이유로 사용이 중단되어 있다. 이와 같은 문제점을 해결하기 위해서는 시스템의 재구축 또는 개정작업이 수반된다. 본 논문에서는 학교급식관리의 내실화를 실현하기 위해 학교종합정보관리 시스템의 개선점을 도출하고 그 실현 방안을 제시하였다.

시스템의 구조는 확장 또는 부하 균형을 위해 재구성 및 재구조화가 필요하다. 이러한 상황에서, 다수의 새로운 시스템이 기존의 시스템에 추가되며 이전의 시스템이 담당하고 있던 역할의 일부분이 새로 추가된 시스템으로 분산된다. 이러한 자원 관리는 몇 가지 문제를 야기시키는데, 가장 큰 문제점은 일부 시스템 또는 전체 시스템의 재구조화를 위해 일정기간 동안 서비스 제공이 중단된다는 점이다. 이 논문에서는 동적인 자원관리가 요구되는 변화하는 환경에서 자동적으로 새로운 시스템을 추가하고 적응적으로 시스템의 부하를 재조정할 수 있는 이동 컴퓨팅 모델을 제안한다.

The purpose of this study is to provide a more persuasive organ donation campaign based on the understanding of the public based on the personal characteristics and value factors of various age groups. The influence of personal characteristics and value factors (organ donation attitude, organ donation knowledge, self - efficacy, internal medicine, attitude toward discontinuation of life - saving treatment) on the intention of organ donation among 20s to 60s or older was examined. Demographic variables that were predicted to affect individual behavioral intentions such as gender, age, and religion were included. The value factors were also included attitudes toward life-sustaining treatment and afterlife view to identify potential factors. The results showed that attitude toward organ donation, knowledge of organ donation, self-efficacy, attitudes toward life-sustaining treatment had a significant positive effect on organ donation intention.

In this study, we explored the characteristics of instrumental genesis in high school students' scientific inquiries. Twenty-three 10th to 11th graders in a science research club participated in this study. The students in 6 groups autonomously planned and performed their own scientific inquiries for one semester. Their activities were videotaped and recorded. Semi-structured interviews were conducted. Material request papers and group worksheets were also collected for analysis. The results of the study suggested that students' practices were categorized as instrument genesis. When instrument genesis did not occur, the cases at the beginning of and during the practice were described respectively. Instrumental genesis was found to appear in three categories: instrumentation; instrumentation and instrumentalization; and instrumentalization. The characteristics and details of case represented in each category were described and discussed related to affordance as the results of the study. On the bases of the results, the implications for the reconsideration of the instruments in school science inquiries are discussed.

Purpose: This study is intended to confirm the business disruptive risk in the Serious Accidents, and propose a plan to comply with the Serious Accidents Punishment Act through the Disaster Mitigation Activity Management System. Method: Through literature review and case studies, the requirements and characteristics of each of the Serious Accidents Punishment Act, the Disaster Mitigation Activity Management System, and ISO 45001 were compared and analyzed, and implications were derived. Result: The business disruption and financial adverse effects caused by industrial accidents were identified. Based on this and by using the Disaster Mitigation Activity Management System, measures to link the documentation requirements of the the Serious Accidents Punishment Act to the Disaster Mitigation Activity Management System, and to manage the implementation records of the Serious Accidents Punishment Act's duty were derived. Conclusion: When establishing and operating the Disaster Mitigation Activity Management System, it can not only comply with the Serious Accidents Punishment Act but also contribute to maintaining business continuity and ESG management through the prevention of various disasters and the minimization of secondary damage, etc.

Social networking sites (SNS), such as Facebook, provide abundant social comparison opportunities. Given the widespread use of SNSs, the purpose of the present study was to examine the impact of exposure to social media-based social comparison on user's negative emotions and discontinuous use intention on SNS. We present evidence that under the use of SNS, social comparison activities diverge into three patterns, with explicit self-evaluation desire made against similar target (lateral comparison), self-defense desire made against less fortunate target (downward comparison), and self-enhancement desire made with more fortunate target (upward comparison). Such social comparison processes frequently arise, as people are increasingly using on SNSs, the downward contacts ameliorating self-esteem with positive emotions, but the upward contacts and standard contacts with lateral status enabling a person to compare his or her situation with others and simultaneously increase negative emotions due to its differences with others. In other words, as people increasingly relying on SNSs for a variety of everyday tasks, they risk overexposure to upward or standard social comparison information that may have a cumulative detrimental impact on future intention on SNS use. This study with survey with 209 SNS users found that these negative emotions lead to negative fatigue (attitude) and then discontinuous use intention (behavior) on SNS. Our findings are among the first to explicitly examine discontinuous use intention on SNS using social comparison theory and our results are consistent with those of past research showing that upward social comparisons can be detrimental.

In recent years, the software vulnerability becomes an important problem to the safety in operating system kernel. Many organizations endeavor to publish patches soon after discovery of vulnerability. In spite of the effort, end-system administrators hesitate to apply the patches to their system. The reasons of hesitation are the reboot disruption and the distrust of patches. To solve this problem we propose a dynamic update system for non-updatable kernel, named DUNK. The DUNK provides: 1) a dynamic update mechanism at function-level granularity to overcome the reboot disruption and 2) a safety verification mechanism to overcome the distrust problem, named MAFIA. In this paper, we describe the design of DUNK and detailed algorithm of MAFIA.

RISC-V is a free and open ISA enabling a new era of processor innovation through open standard collaboration. Born in academia and research, RISC-V ISA delivers a new level of free, extensible software and hardware freedom on architecture, paving the way for the next 50 years of computing design and innovation. In this paper, according to the emergence of RISC-V architecture, we describe the RISC-V processor instruction set constituted by arithmetic logic, memory, branch, control, status register, environment call and break point instructions. Using ModelSim and Quartus-II, 38 instructions of RISC-V has been successfully simulated and synthesized.

석탄 가스화기 내에서 슬래그의 축적에 의한 막힘 현상 등으로 발생 가능한 조업중단을 예방하기 위해 탄의 종류에 따른 슬래그의 유동을 정확히 예측하는 것은 중요하다. 슬래그의 유동은 원료인 석탄의 회 성분 조성 그리고 가스화기 온도의 영향을 크게 받는다. 회가 용융된 형태인 슬래그의 융점 특성을 파악하여 슬래그 거동을 예측하기 위해서는 회를 조성하고 있는 주성분의 비율 뿐 아니라 소량의 성분들도 고려하여야 한다. 또한, 가스화기 조업 조건 중 수증기 분압이 슬래그 점도에 미치는 변화를 파악하여 공정 조건 확립 및 슬래그 계통 제어 로직에 반영 할 수 있다. 따라서, 대표적 열화학 평형계산 프로그램인 Factsage를 이용하여 슬래그 성분의 액상선 온도를 예측해보았다. 슬래그는 회 성분의 조성에 따라 결정 슬래그와 유리 슬래그로 나눌 수 있다. 본 연구에서는 결정 슬래그로는 Alaska Usibelli 탄을, 유리 슬래그로는 Kideco 탄의 조성을 사용하여, 가스화기 조업 조건 중 수증기의 분압에 따라 석탄 슬래그의 형성 및 점도 변화에 직접적인 영향을 미치는 결정 형성에 대한 상관관계를 예측해 보았다. 또한, 슬래그 유동에 영향을 줄 수 있는 요인으로써, 석탄의 품질을 결정하는 인자인 Base/Acid Ratio, Iron in Ash, Calcium in Ash, Silica-to-Alumina Ratio, Inron-to-Calcium Ratio를 달리 변화시켜가며 슬래그 점도 변화에 직접적인 영향을 미치는 결정 형성을 예측하였다. 이 예측결과는 향후 실험 데이터와 비교하여, 슬래그 처리 부분의 모니터링에 기초 자료로 활용될 뿐 아니라, 슬래그점도 측정 시스템의 운전 파라미터를 도출하는데 이용 가능할 것이다.
