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.

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.

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)

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.

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 과정에서의 언어적 행동과 학업 성취도와의 관계

노태희,임희준,박수연 한국과학교육학회 1999 한국과학교육학회지 Vol.19 No.3

본 연구에서는 중학교 1학년 37명을 대상으로 과학 수업에서 협동학습을 실시하고 소집단 협동학습 과정을 녹음/녹화하였다. 이를 토대로 협동학습 과정에서 발생하는 언어적 행동 유형을 범주화하고 이들과 학업 성취도 사이의 관계를 조사하였다. 학생들의 언어적 행동은 크게 학습 내용과 관련된 행동 및 조활동 관리와 관련된 행동으로 구분되었다. 학습 내용과 관련된 행동은 도움 주기, 문제 읽기, 도움 요청하기로 세분되었으며, 이 중 도움 주기 행동이 가장 많았다. 학생들의 언어적 행동과 학업 성취도 사이의 단순 상관 관계를 조사한 결과, 도움 주기와 문제 읽기 행동이 학업 성취도와 정적인 상관이 있었다. 도움 주기 중 구체적인 내용을 제공하는 행동은 학업 성취도와 매우 밀접한 관계가 있었다. 한편, 부분 상관을 통하여 언어적 행동과 학업 성취도 향상과의 관계를 조사한 결과, 상위 수준의 사고를 요하는 적용 영역 성취도의 향상만이 구체적인 내용 제공하기를 비롯한 일부 언어적 행동과 정적인 상관이 있었다. When 37 7th-graders learned science in cooperative learning environments, their small-group processes were audio/video taped. The verbal behaviors that appeared in cooperative learning processes were categorized, and the relationships between verbal behaviors and academic achievement were investigated. Students' verbal behaviors were classified into learning behaviors and management behaviors. Learning behaviors were further coded into giving help, reading problem, and asking help. Giving help was the most frequent behavior among the categories. In studying zero-order correlation between verbal behaviors and academic achievement, giving help and reading problem were found to have positive relationships with academic achievement. Giving specific content, which is a subcategory of giving help, showed the closest correlation with academic achievement. In studying partial correlation between verbal behaviors and the improvement of academic achievement, only application subtest score, which demands higher-order thinking, was positively related with some verbal behaviors including giving specific content.
