The systematic management of technology infrastructure increasingly becomes critical as it represents the driving power for creating competitive advantage of nations and enterprises. In this sense, public facility and equipment, which is one major asset of technology infrastructure, should be managed effectively, systematically and efficiently to increase its overall equipment effectiveness. However, the manual and off-line communication was the unique way to communicate between the suppliers who provide facilities in the public sector and the customers who utilize the facilities in the industrial sector. This communication way caused invisibility of available usage time and increase of idle time, thereby decreasing the equipment effectiveness. This paper presents an web-based scheduling system that enables real-time collaboration and information sharing for increasing the equipment effectiveness. The designed system performs scheduling, facility management, order management and customer relationship management in an on-line platform, and carries out the processing and storing of relevant information in an integrated database. The paper includes a development approach to identify business process models and standardized system models by using object-modeling technique. The deliverable of the present work will contribute to increasing the equipment effectiveness by enhancing visibility, transparency and predictability by means of the integration with a legacy Enterprise Resource Planning.

There have been growing concerns among people about food safety due to insufficient information on foodborne pathogens. In this study, we developed a risk priority of 15 foodborne pathogens. For the priority determination we collected risk profile criteria information from CODEX Alimentarius Commission and developed countries. The basis for criteria we selected from information of surveillance were frequency and severity of disease,frequency of consumption and probability of cross-contamination. We also considered foodborne pathogens which have been managed in developed countries though those pathogens are not currently managed appropriately in Korea. Priorities were divided into three groups following these consideration. The first priority group includes Norovirus,pathogenic E. coli, Salmonella spp, Clostridium botulinum and Listeria monocytogenes. The second priority group includes Vibrio parahaemolyticus, Stapylococcus aureus, Campylobacter jejuni and Bacillus cereus, and the third priority group includes Clostridium perfringens, Yersinia enterocolitica, Shigella spp, Cronobacter sakazakii and Hepatitis A virus. Our results could be applied to prevent foodborne illness from fresh produce.

학습자의 주관적 웰빙을 위한 리터러시 교육의 가능성 탐색

이채윤 ( Lee Chaeyun ),최인찬 ( Choi Inchan ),조병영 ( Cho Byeong-young ) 한국어교육학회 2023 국어교육 Vol.- No.183

오늘날의 교육은 학습자가 자신의 인격을 성장시키고 지속가능한 방식의 좋은 삶을 살아가도록 하는 것에 방점을 둔다. 이에 국어교육 역시 학습자의 건강하고 행복한 삶의 영위를 궁극적인 목표로 두고, 학습자가 다양한 담화 맥락의 의미 구성 과정을 경험하면서 자신의 삶을 긍정적으로 이해하고 성찰하도록 도울 필요가 있다. 이러한 맥락에서 이 연구는 주관적 웰빙과 리터러시 개념을 탐구하고, 리터러시 경험을 통해서 학습자의 주관적 웰빙을 긍정적으로 변화시키는 교육적 실제의 가능성을 검토하였다. 이때 주관적 웰빙을 ‘삶에 대한 이해, 정서에 대한 태도, 자아실현’으로, 리터러시를 ‘능력과 역할, 사회적 영향력, 실천과 성장’으로 해석함으로써 두 개념을 교육의 맥락에서 논하고자 하였다. 그리고 그간의 국어교육 연구를 바탕으로 리터러시와 주관적 웰빙이 어떻게 상호 연결될 수 있을지 확인하고, ‘전환적 의미 디자인’의 관점에서 학습자의 주관적 웰빙을 위한 리터러시 교육의 원리를 제안하였다. 이러한 시도는 국어교육이 학습자의 행복한 삶을 어떻게 지원할 수 있을지를 고민한 결과이자, 우리의 교육이 미래 세대의 유연한 성장과 지속가능한 삶을 목표로 한 실천이 되어야 한다는 요구에 응하기 위한 것이라 하겠다. Contemporary education is centered on fostering learners’ personal growth and enabling them to lead a good and sustainable life. In line with this objective, Korean language education places the ultimate goal on promoting learners’ healthy and happy lives. It is crucial to assist learners to positively understand and reflect on their lives by experiencing the process of meaning-making in various discourse contexts. This study delves into the concepts of subjective well-being and literacy, examining the potential of educational practices to positively transform learners’ subjective well-being through literacy practices. Subjective well-being is interpreted as ‘understanding of life’, ‘attitude toward emotions’, and ‘self-realization’, whereas literacy is interpreted as ‘abilities & roles’, ‘social influence’, and ‘practice & growth’. By interpreting these two concepts within the context of education, this study discusses their connections. Building upon previous research on Korean language education, this study investigates how literacy and subjective well-being can be interconnected. It also proposes principles for literacy education for learners’ subjective well-being from the perspective of ‘transformative design for meaning’. This endeavor is a result of contemplating how Korean language education can contribute to learners’ happy lives and response to the demand for our education to be a practical effort toward the flexible growth and sustainable lives of future generations.

Buckwheat (Fagopyrum esculentum) is one of the traditional crops and there is a growing global attention as a healthy food because of its rich nutrition. Buckwheat allergy is an IgE mediated immediate-type reaction and it is considered to be a critical allergen because it causes severe allergic reactions by small amount of intake particularly in children. In this issue of Buckwheat allergy, research papers about various topics - major allergens of buckwheat, clinical reports, detection methods and methods to reduce allergenic reaction - were reviewed. Major buckwheat allergens reported and listed on IUIS are Fag e 1 with molecular weight 24 kDa, Fag e 2 with molecular weight 16 kDa and Fag e 3 with molecular weight 19 kDa. PCR and ELISA methods have been used to detect buckwheat allergens. Recently, the LC/MS method has been developed to apply to detect buckwheat allergens. In addition to detection methods development, there have been efforts to reduce buckwheat allergens using chemical and/or physical methods, but not commercialized yet.

이 연구는 OECD Education 2030 보고서에 제시된 학생 주도성의 개념을 면밀히 탐구하여 그 개념과 관련된 쟁점을 정리하고, 국어교육 관련 학술지에 게재된 논문의 학습자 중심 교육이 실현된 양상 속에서 학생 주도성의 면모를 확인함으로써 국어 수업의 설계와 실행에서 학생 주도성 실현의 가능역을 탐색해 보고자 하였다. 학생 주도성은 교육 내용으로서의 주도성과 학습 과정에서의 주도성으로 나뉠 수 있었으며, 협력적 주도 학습과 집단적 주도성을 포함하는 넓은 개념임을 확인할 수 있었다. 이를 국어 수업에 실현할 수 있는 가능역을 탐색하기 위해 『우리말교육현장연구』의 학습자 중심 교육을 실천한 수업 사례 21건을 분석한 결과, 수업 목표 측면에서의 시사점과 수업 방법의 설계 및 실행 측면에서의 시사점을 얻을 수 있었다. 학생 주도성 실현을 위해서는 국가 차원의 교육과정을 교사 차원의 교육과정으로 재구성하고, 학생들에 대한 충분한 이해를 바탕으로 학생들과 상호 협력하여 수업을 꾸려나가는 교사 전문성이 필요하다. This study aimed to explore the possibilities of student agency in Korean language classes by summarizing issues related to the concept of student agency in the OECD Education 2030 project and examining various aspects of learner-centered education in previous research on Korean language education. Student agency can be divided into agency as teaching content and agency in the learning process. Also, it is a broad concept that includes co- agency and collective agency. To explore the possibility of realizing student agency in Korean language classes, 21 cases that practiced learner-centered education in an academic journal, “Field Studies in Korean Language Education” were analyzed, and implications in terms of class goals, class design, and progress were obtained. Findings confirmed that teacher professionalism is required to reorganize the national curriculum into a teacher-level curriculum, and it is essential that teachers cooperate with students based on an adequate understanding of their needs.

Purpose: Major hepatic resection is sometimes inevitable in patients with impaired liver function. We evaluated risk factors that cause postoperative liver failure after major hepatic resection in patients with over a 10% Indocyanine Green Retention rate at 15 minutes (ICGR15). Methods: From Apr. 2002 to Aug. 2009, 32 patients who had over a 10% rate of ICGR15 underwent major hepatic resection (≥4 Couinaud segments). Among the 32, 9 patients showed postoperative liver failure (less than 50% prothrombine time and/or 5 mg/dl or higher of total bilirubin). This high-risk group was compared to the rest who constituted a low-risk group. Results: Patients with esophageal varix were more common in the high risk group (4 versus 2, p=0.043). Other clinicopathologic features showed no difference between the two groups. We had 2 in-hospital deaths in the high risk group. Conclusion: Great care is needed in patients with esophageal varix and limited liver function during major hepatic resection.
