Security infrastructure of Educational Network responds to threats by collecting and analyzing security events from various information protection system based on the integrated management system. Even if this system provides useful and detailed information to the administrator, there are some problems that this system does not provide effective response process and management systems for various threatening situations and the simultaneous threat processes. To solve this problem, we propose and develop security agents that enable the administrator to effectively manage integrated security for Educational Network. The proposed solution provides the administrator with efficient management techniques and process scheduling for various security events so that the administrator can response promptly to problems with the initial threat to Educational Network. 교육망의 보안 인프라는 통합관리시스템을 기준으로 다양한 정보보호시스템의 보안 이벤트를 수집하고 분석을 통하여 위협을 관리하고 대응한다. 이러한 체계는 관리자에게 유용하고 자세한 정보를 제공하지만, 다양한 위협 상황과 동시 다발적인 위협에 대해서 효과적인 대응 프로세스와 관리체계를 제공하지 못하고 있는 문제점을 많이 가진 교육망에 대한 해결방안으로 관리자에게 다양하고 세부적인 정보 제공보다는 관리자가 초기 위협에 신속하게 대응할 수 있도록 관리기술과 다양한 보안 이벤트들의 처리 스케줄링을 통해서 통합보안관리가 가능하도록 보안 에이전트를 제안 개발하였다.

최근 미래 인재가 갖추어야 할 21세기 핵심 역량으로서 집단 창의성이 강조됨에 따라, 집단 창의성 계발 방안으로서 협업과 공감을 강조하는 디자인적 사고를 과학 교육에 도입하는 방안을 고려해 볼 필요가 있다. 그리고 디자인적 사고의 효과적인 도입과 전략 마련을 위하여 디자인적 사고에 대한 이해가 선행될 필요가 있다. 이에 이 연구에서는 일반모델 덧씌우기 방법, 초점집단면접, 중요사건기법 분석을 통해 디자인적 사고의 속성을 규명하였다. 연구 결과, 4개의 역량군과 15개의 핵심 역량을 추출할 수 있었다. 즉, "팀의 조직", "의사소통", "자기조절", "설득력", "주도성"의 5개 역량으로 구성된 협업 역량군, "분석적 사고력", "전략적 사고력", "직관적 사고력"의 3개 역량으로 구성된 통합적 사고 역량군, "사용자 지향", "관계형성", "대인이해"의 3개 역량으로 구성된 인간중심 역량군, "성취지향", "정보수집", "호기심", "유연성"의 4개 역량으로 구성된 다학제 역량군을 들 수 있다. 이 연구 결과는 국내 과학 교육에 디자인적 사고를 효과적으로 도입하고, 집단 창의성 계발을 위한 프로그램 개발이나 전략 마련 등을 위한 기초 자료로서 활용될 수 있을 것으로 기대된다. Group creativity has recently been heightened as a core competence in the 21st century. Therefore, there is a need for introduction of concepts on design thinking emphasizing the collaboration and empathy to science education as an effective method for fostering group creativity. Understanding design thinking for effective introduction should be preceded, so we explore the characterizations of design thinking through the generic model overlay method, focus group interview, and critical incident technique analysis. The results reveal 4 cluster units of competency and 15 core competencies. The collaboration cluster consists of 5 competencies and they are as follows: organization of the team, communication, self-control, persuasiveness, and initiative competency. The integrative thinking cluster consists of 3 competencies and they are as follows: analytical, strategic, and intuitive thinking competency. The human-centeredness cluster consists of 3 competencies and they are as follows: user-orientation, relationship building, and interpersonal understanding competency. The multidisciplinary cluster consists of 4 competencies and they are as follows: achievement orientation, information seeking, curiosity, and flexibility competency. Findings are expected to provide the basic data for developing programs and establishing strategies in order to foster group creativity as well as introducing design thinking to science education effectively.

Hypokalemia is a common finding in various clinical settings; it is associated with diuretic use and loss of potassium via the gastrointestinal tract. Less common causes are renal tubular acidosis, diabetic ketoacidosis, excess insulin, primary hyperaldosteronism, and medications, such as amphotericin B. Nafcillin, a narrow-spectrum penicillin class antibiotic, which is selectively prescribed for methicillin-susceptible Staphylococcal aureus infections, and is commonly associated with gastrointestinal side effects, such as nausea, vomiting, and abdominal pain. However, in rare cases it can cause hypokalemia, which is usually overlooked. Severe hypokalemia was detected in a 59-year-old male patient hospitalized due to traumatic cerebral hemorrhage who received 12 g of nafcillin per day for more than 2 weeks for sepsis caused by methicillin-sensitive Staphylococcus epidermidis. We confirmed the association between nafcillin and hypokalemia through further evaluation and a review of the relevant literature. Clinicians should be aware of hypokalemia as a complication when using high doses of nafcillin. (Korean J Med 2021;96:139-142)

Fibro-osseous pseudotumor is an unusual ossifying fibro-proliferative lesion. Typically, this lesion affects the young adults, mainly women, and presents as a painful, localized, fusiform, and often erythematous swelling in the soft tissue of the fingers, especially the region of the proximal phalange. We present a case of fibro-osseous pseudotumor on the left index finger of a 22-year-old woman. Diagnosis was confirmed by histopathologic features, followed by complete excision of the lesion. At the 7-month follow-up, there was no recurrence. We suggest that fibro-osseous pseudotumor should be considered in the differential diagnosis of any digital mass.

Bizarre parosteal osteochondromatous proliferation (Nora`s lesion) is a rare lesion with a tendency to recur. It is usually a solitary lesion that most often develops on the hands and feet. We now present a case of bizarre parosteal osteochondromatous proliferation initially misdiagnosed as subungual exostosis on the left great toe of a 13-year-old boy. The diagnosis was confirmed by radiologic and histopathologic features, followed by complete excision of the lesion. He had a relapse after two months and was treated with re-excision. We suggest that bizarre parosteal osteochondromatous proliferation should be considered in the differential diagnosis of any digital mass. (Korean J Dermatol 2011;49(9):830~832)

이도현 ( Do Hyun Lee ),윤지현 ( Ji Hyun Yoon ),강성주 ( Seong Joo Kang ) 한국과학교육학회 2015 한국과학교육학회지 Vol.35 No.3

이 연구에서는 우리나라의 과학 교육에 도입 가능한 디자인적 사고프로세스를 제안하고, 집단 창의성의 발현 측면에서 프로세스의 타당성을 검토하였다. 이를 위해 국외에서 개발된 다양한 디자인적 사고프로세스로부터 우리나라 과학 교육 상황에 적용 가능한 디자인적 사고 프로세스를 선정하고, 이를 수정 및 보완하였다. 그리고 개발된 디자인적 사고 프로세스를 바탕으로 교육 프로그램을 만들고, 이를 고등학교 학생들에게 적용하였다. 연구 결과, ‘관련 지식 이해’, ‘공감’,‘관점 공유’, ‘아이디어 생성’, ‘프로토타입’의 다섯 단계로 디자인적사고 프로세스를 제안할 수 있었다. 그리고 이를 과학 교육 현장에 적용한 결과, 관련 지식 이해 단계에서는 관계 형성과 정보 수집 요소를, 공감 단계에서는 사용자 지향, 관계 형성, 대인 이해 요소를 확인할수 있었다. 관점 공유 단계에서는 팀의 조직 요소를, 아이디어 생성 단계에서는 분석적, 전략적 사고력 요소를 확인할 수 있었다. 마지막으로, 프로토타입 단계에서는 의사소통과 분석적, 전략적 사고력 요소를 확인할 수 있었다. 집단 창의성 과정에 능숙한 전문가들로부터 발견되는 집단 창의성의 핵심 속성을 학생들로부터 모두 확인할 수는 없었지만, 이 연구에서 개발된 프로세스를 통해 우리나라 학생들이 집단 창의성이 발현되는 과정을 경험하고, 관련 가치를 배울 수 있는 가능성이 있음을 확인할 수 있었다. In this study, we suggested the design thinking process that was possible to be introduced in science education and also examined the validity of the process in terms of group creativity. To do this, the design thinking process applicable to science education was selected from a variety of design thinking processes developed abroad, and then the process was modified and supplemented. We created the education program based on the developed design thinking process and applied it to high school students. The results revealed that we could offer the design thinking process through the five stages: ‘understanding knowledge’, ‘empathy’, ‘sharing perspective’, ‘generating idea’, and ‘prototype’. With the results of the application of the program, we could confirm the relationship building and information seeking attributes in the understanding knowledge stage and the user-orientation, relationship building, and interpersonal understanding attributes in the empathy stage. We could also find the organization of the team attribute in the sharing perspective stage and the analytical · strategic thinking attributes in the generating idea stage. Finally, the communication and analytical · strategic thinking attributes in the prototype stage were confirmed. All of the key attributes of the group creativity found from skilled professionals were not confirmed from the students. However, we could ascertain the possibilities that the students should experience the process of group creativity and learn the relevant values through the developed design thinking process.

A 6-year-old boy presented with a fast-growing, 0.8×0.7 cm-sized, dome-shaped, erythematous nodule on the back. Histopathologically, the lesion showed a spitzoid melanocytic proliferation from the dermo-epidermal junction to the reticular dermis. Melanocytes arranged in nests were epithelioid and spindle-shaped with abundant eosinophilic cytoplasm. The histopathological and clinical features were consistent with atypical Spitz nevus in that they showed no Kamino body, prominent cellular density, more than three mitoses per high power field, a high Ki-67 level, large size, and the lesion was located at an unusual location. Herein, we report a case of an atypical Spitz nevus on the back of a 6-year-old boy. (Korean J Dermatol 2011;49(12):1116~1118)
