박수연(Park, Soo Youn),김승인(Kim, Seung In) 한국디지털디자인협의회 2014 디지털디자인학연구 Vol.14 No.1

디지털 기술이 발달하면서 사용자들이 자신의 삶을 기록하고자 하는 욕구가 증가하였고 이와 함께 라이프로깅(lifelogging) 트렌드가 확산이 되고 있다. 이러한 트렌드를 반영하여 스마트 디바이스(smart device)에서 사용가능한 애플리케이션과 전용 단말기가 등장하고 있으며 서비스의 질을 높이기 위한 연구가 활발하게 진행되고 있다. 본 논문에서는 애플리케이션 데이원(Dayone)과 모멘토(Momento)를 선정하여 타 서비스에 비해 개발기간이 짧아 사용성 문제점을 빠르게 도출해야하는 앱의 특성을 살려 사용성 평가를 실시하고 사용자들의 사용행태를 파악하여 관련 서비스들의 기능과 활용도를 개선시킬 수 있는 가이드라인을 제시하였다. 연구방법으로는 문헌연구와 휴리스틱 평가 방법(heuristic evaluation)을 통하여 평균 점수를 통계화하였다. 또한 사용자의 사용행태 측정을 위해 태스크(task)평가 항목을 설계하여 공통점과 차이점을 측정해 문제점을 도출하였으며 애플리케이션 화면 구성요소에 대한 만족도 설문조사와 인뎁스 인터뷰를 실시하였다. 이러한 사용성 평가로 분석된 데이원과 모멘토 애플리케이션의 개선점을 다음과 같이 제언하였다. 첫째, 라이프로깅의 특성을 고려하여 사용자화가 가능한 인터페이스 디자인이 가능하도록 한다. 둘째, 두 애플리케이션에서 드러난 문제점인 사용자의 흐름을 방해하고 시간을 지체하게 되는 깊은 뎁스와 불필요한 단계는 줄인다. 셋째, 아날로그 감성과 디지털의 장점을 적절히 융합시켜 다른 유사한 애플리케이션과 차별화를 시킨다. 본 연구의 결과는 추후 진행되는 신뢰성 높은 연구 분석결과와 함께 참고 되어 현존하고 있는 라이프로깅 애플리케이션의 사용성을 높이고 서비스의 질적 향상에 기여할 수 있을 것으로 기대한다. With the digital technology development, users desire to record their own lives have been increased. With this, lifelogging trend has become widespread. More recently, reflecting these trends, the dedicated terminal and the applications available in smart device and study to improve the quality of service have been actively appeared. In this paper, in order to evaluate usability of lifelog application, Dayone and Momento application have been selected for evaluation. From the result of usability evaluation and understanding the usage patterns of users, we provided guidelines which can improve the related service and the utilization of functions. I performed literature research and the heuristic evaluation. Further more, I experimented the task to measure the usage pattern of the user and problem by measuring the similarities and differences and completed survey and in-depth interview. From the result, I have suggested as follows improvements of both applications. First, to allow the design of interface can be customized in consideration of the characteristics of the life log. Second, deep depths and needless steps could be reduced which are problems founded in both applications. Third, provide a service with both the advantages of digital and analog’s sensibility to allow differentiation from other similar applications. From the results of this study, I expected the improvement of the usability of lifelog applications and contribution to improve the quality of lifelog service.

항 EPO 항체에 의한 PRCA는 매우 드물지만 적절한 치료를 하지 않으면 지속적인 적혈구 수혈이 필요하게 되므로 문제가 된다. PRCA가 진단되면 ESA 투여를 중단하고 면역억제 치료를 하는 것이 필요하다. 특히 항 EPO 항체는 모든 종류의 ESA 제제와 교차반응을 하므로, 어떤 ESA 제제로도 교체 투여하지 않아야 한다. 국내에서는 3예의 증례가 보고되었는데, 면역억제 치료를 시행하였으나 모든 예에서 치료에 성공하지 못하였다. 저자들은 EPO-α를 피하 주사하던 환자에서 발생한 PRCA를 면역억제 치료 후에 darbepoetin-α로 교체 투여하여 성공적으로 치료한 예를 경험하였기에 문헌고찰과 함께 보고한다. Patients with erythropoiesis-stimulating agent (ESA)-induced pure red cell aplasia (PRCA) should not routinely be switched to an alternative ESA or to darbepoetin-α because anti-erythropoietin (anti-EPO) antibodies cross-react with all kinds of recombinant ESAs. We present a case of ESA-induced PRCA in a 69-year-old man on hemodialysis whose anemia improved with reintroduction of darbepoetin-α following immunosuppressive therapy. The patient developed severe anemia after 15 months of subcutaneous administration of erythropoietin-α. After the diagnosis of PRCA, erythropoietin-α was discontinued and immunosuppressive therapy with a combination of prednisolone and oral cyclophosphamide was initiated. After 4 months of immunosuppressive therapy, the anti-EPO antibody titer was markedly decreased; however, esophageal candidiasis developed. Additional therapy with cyclosporine alone instead of prednisone and cyclophosphamide was performed, and anti-EPO antibody was subsequently not detected. Darbepoetin-α was then reintroduced, and the patient`s anemia improved without red cell transfusion. In conclusion, ESA-induced PRCA was successfully treated with reintroduction of darbepoetin-α following immunosuppressive therapy. (Korean J Med 2013; 84:742-746)

Styela clava tunic is generated in large amounts as a waste from S. clava processing plants and leads to environmental problems. It destroys the beach scenery and causes a bad smell and pollution by trashing on the seashore. Therefore, purpose of this study was to investigate antioxidant and antihypertensive activities of different solvent extracts from S. clava tunic for recycling of fishery waste. Antioxidant and antihypertensive activities of all extracts were concentration-dependent. Of extracts, hot water extract showed the highest DPPH radical scavenging activity with the lowest effective concentration (EC50) value (0.733 mg/ml). Chloroform extract exhibited the highest metal chelation activity with the lowest EC50 value (2.696 mg/ml). Autoclaved water extract showed the highest NO radical scavenging activity with the lowest EC50 value (0.491 mg/ml) and n-hexane extract showed the highest reducing power (A700=1.897 at 100 mg/ml). And n-butanol extract showed the highest SOD-like activity with the lowest EC50 value (19.116 mg/ml) and ACE inhibition activity with the lowest inhibitory concentration(IC50) value (0.149 mg/ml). These results indicate that extracts obtained from S. clava tunic may potential candidate to reduce diseases caused by various oxidative stresses and hypertension.

Ankylosing spondylitis (AS) is a chronic inflammatory disorder, commonly characterized by inflammation of axial skeleton and development of enthesopathies. Tumor necrosis factor inhibitors (TNFi) shows good therapeutic responses in AS patients without good response to non-steroidal anti-inflammatory drugs. Although TNFi are relatively safe for AS patients, serious opportunistic infections, including tuberculosis and fungal infection, could develop. Here, according to our knowledge, we report a first Korean case of pulmonary cryptococcosis in a patient with AS treated with etanercept. A 64 year-old man with AS visited due to a newly appeared pulmonary nodule on a routine chest radiography. He had been administered etanercept for 5 months. Histologic findings of the lung nodule showed characteristic features of cryptococcosis. Etanercept was discontinued and oral fluconazole was administrated, as there was no evidence of central nervous system involvement. After 7 months of treatment, chest CT showed an improvement of the pulmonary lesion.

저자들은 급성회색질척수염과거력이 있는 환자에서 새로 발생한 근육 위약이 소아마비후증후군으로 진단되었다가, 근육위약과 피부발진의 증상이 진행하여 피부근염으로 최종진단 후 고용량의 스테로이드와 면역억제제 사용으로 증상과 검사실 소견이 호전되었던 예를 경험하여 문헌고찰과 함께 보고하는 바이다. Dermatomyositis (DM) is an idiopathic inflammatory myopathy, characterized by inflammation of the proximal skeletal muscles and typical skin manifestations, which results in symmetric muscle weakness. A 43- year-old man was presented with skin rash and left leg weakness, and he had a history of poliomyelitis. Initially, he was diagnosed as having post-polio syndrome (PPS) due to unilateral muscle weakness and a result of an the electromyography (EMG), which had shown patterns of PPS. After 4 months with conservative therapy for PPS, weakness of bilateral upper arms had developed and skin rashes on his entire body had aggravated and progressed. He was diagnosed as having dermatomyositis, based on elevated muscle enzyme levels, typical skin rashes, and typical EMG findings, which indicated muscle disease. When a patient with previous poliomyelitis has a newly developed muscle weakness or pain, we should consider various possible causes other than PPS.

협동학습 전략에서 소집단 구성 방법의 효과

노태희,임희준,박수연,차정호 한국과학교육학회 1998 한국과학교육학회지 Vol.18 No.1

본 연구에서는 소집단 구성 방법을 달리한 두 가지 협동학습-HML 협동학습과 HL/MM 협동학습-교수 방법이 학생의 학업 성취도, 과학 수업에 대한 태도, 수업 환경에 대한 인식, 자아존중감에 미치는 효과를 조사하였다. HML(High-Medium-Low ability grouping) 협동학습은 상·중 ·하위 수준의 학습자를 고루 포함하도록 소집단을 구성한 방식이고,HL/MM(High-Low/Medium-Medium ability grouping) 협동학습은 상위 ·하위 수준의 학습자로 구성된 소집단/중위 ·중위 수준의 학습자로 구성된 소집단이 공존하는 방식이다. 본 연구는 중학생 3개 학급(통제 집단 1학급, HML협동학습 집단 1학급, HL /MM 협동학습 집단 1학급)을 대상으로 물질의 특성 단원에 대하여 약 5주간 실시되었다. 수업 처치 전에 논리적 사고력, 과학 수업에 대한 태도, 수업 환경에 대한 인식과 자아 존중감 검사를 실시하였고, 수업 처치 후에 학업 성취도, 과학 수업에 대한 태도, 수업 환경에 대한 인식과 자아 존중감 검사를 실시하였다. 연구 결과, 전체 학업 성취도에서 수업 처치의 주효과는 나타나지 않았으나, 수업 처치와 사전 성취 수준 사이에 상호작용 효과가 있었다. 상위 수준 학습자의 경우 HL/MM 협동학습 집단의 성취도가 가장 높게 나타났다. 중위 수준 학습자의 경우에 이질적으로 구성된 HML 협동학습 집단의 성취도가 가장 높게 나타났으며, 중위 수준 학습자들로만 소집단을 구성한 HL/MM 협동학습 집단의 성취도는 통제 집단과 거의 차이가 없었다. 반면, 하위 수준 학습자의 경우에는 상 ·중 · 하위 수준 학습자들로 구성된 HML 협동학습 집단의 성취도는 다른 두 집단에 비하여 낮게 나타났으며, HL/MM 협동학습 집단의 성취도는 통제 집단과 거의 유사하였다. 과학 수업에 대한 태도와 자아 존중감에서는 수업 처치의 주효과 및 사전 성취 수준과의 상호작용 효과가 없었다. 그러나, 수업 환경에 대한 인식에서는 두 가지 협동학습 집단의 점수가 통제 집단에 비해 유의미하게 높았다. This study investigated the effects of grouping (group composition) in cooperative learning strategy upon students' achievement, the attitude toward science instruction, the perception of learning environment, and the self-esteem. Three different groups were used in this study. For the two treatment groups with cooperative learning strategies, High-Medium-Low ability grouping (HML) and High-Low/Medium-Medium ability grouping (HL/MM) were used. For the control group, traditional instruction was used. Before the instructions, the short-version Group Assessment of Logical Thinking, the test of attitudes toward science instruction, the perception questionnaire of learning environment, and the questionnaire of self-esteem were administered, and their scores were used as covariates. Mid-term examination score was used as a blocking variable. After the instructions, a researcher-made achievement test consisting of three subtests (knowledge, understanding, and application), the test of attitude toward science instruction, the perception questionnaire of learning environment, and the questionnaire of self-esteem were administered. The ANCOVA results revealed that there were significant interactions between the instruction and the level of prior achievement although there were no significant differences in all subtest scores of the achievement test. The high-level students in the HL /MM cooperative group performed better than those in the control group and the HML cooperative group. The low-level students in the HL/MM cooperative group also performed better in the subtest of knowledge than those in the other groups. However, the medium-level students in the HML cooperative group scored better than those in the control group and the HL/MM cooperative group. Significant main effect was also found in the perception of learning environment but not in the attitude toward science instruction and self-esteem. The cooperative groups, regardless of grouping, exhibited more positive perception than the control group.
