A New Method for Improving the Quality of the College Scholastic Ability Test(CSAT)

Myunghwa Kim(김명화) 한국산학기술학회 2014 한국산학기술학회 학술대회 Vol.2014 No.2

In Korea, The College Scholastic Ability Test(CSAT) has an enormous influence on the goals and contents of high school courses, as well as the methods of teaching and learning. Since the CSAT was introduced in 1993, the English listening portion has had fixed types of items. The items are multiple-choices and the questions are given in written Korean. Some multiple-choices are in written Korean whereas others are in written English. As a result, students do not study to improve their communication ability but for the purpose of being able to answer the several fixed types of questions to attain a higher score. In this study, a new type of item is proposed for the English listening portion of the CSAT. There were two groups of participants: The experimental group was given questions and multiple-choices in spoken English, and the control group was given questions and multiple-choices in written English. A comparison of their test results shows that the two groups were slightly different in terms of their average score, the item discrimination index, and item difficulty level. The results suggest that it is the more appropriate to give items in spoken English compared to written English.

최근 한 · 중 · 일 및 한 · 미 FTA가 발효되면 농축산업에 큰 타격을 줄 것으로 예상된다. 수입자유화 이후 외국에서 생산된 농수축산물의 수입이 급증하고 있다. 그러나 질이 낮은 수입산이 국산으로 둔갑하는 일이 자주 발생하면서 농수축산물의 신뢰도 및 판로에 부정적인 영향을 미쳐왔다. 이에 생산이력 관리에 대한 필요성이 많이 요구되어지고 있다. 본 논문에서는 농산물의 유통이력은 물론 기존 시스템에서 제공하지 못한 생장환경이력정보와 시설재배에 따른 자동제어 및 저장고 모니터링 정보를 추가하여 RFID/USN 기반 농산물 이력관리시스템을 설계 및 구현하였다. 본 논문에서 설계 및 구현한 농산물 이력관리시스템은 생장환경모니터링과 이력관리로 구성된다. 첫째, 생장환경모니터링은 USN을 활용하여 농산물이 생산되는 재배지의 환경을 모니터링하고 저장고 및 재배시설의 자동제어기를 모니터링 한다. 생장환경모니터링 정보는 농산물의 생장환경에 대한 상세한 정보를 제공해 줄 수 있으며, 생산자가 영농일지를 자동으로 작성할 수 있도록 정보를 제공한다. 둘째, 이력관리는 농산물의 생산, 출하, 유통, 소비까지 모든 유통단계에서 발생된 이력정보를 소비자에게 제공할 수 있다. 본 논문에서 설계 및 구현한 RFID/USN 기반 농산물 이력관리시스템은 생산자에게 u-IT 농업을 제공하고, 소비자에게 농산물에 대한 신뢰도를 높여줄 수 있다. 또한, 본 시스템을 적용하여 정부의 우수농산물관리제도와 위해요소중점관리기준을 시행하는데 기초자료를 제공할 수 있고, 국내 농산물의 고급화 및 선진화를 달성할 수 있다. Recently, it is expected that the agricultural and stockbreeding industry are damaged by the China-Japan-South Korea FTA and FTA between the United States and South Korea. After free trade, it is increasing to import crops, aquatic products, and livestock which are produced in a foreign land. But it is affected negatively to the trust relationships and markets, because of breaking it out that low grade foreign products are turned into domestic products. For this reason, we need the traceability management system. In this paper, it designs and implements the traceability management system using RFID and USN providing distribution traceability information as well as the traceability information of the growth environment, automatic control according to the facility growing and monitoring of the storehouse. The implemented whole systems consist of the growth environment monitoring and the traceability management. First, the growth environment monitoring shows the environment of plantation and automatic controller of the storehouse and growing facility. This growth environment monitoring information provides the detailed information about growth environment and writing the farming diary automatically by producer. Second, the traceability management provides all of the traceability information such as production, shipment and consumption to consumers. The traceability management system that has been designed and implemented using RFID and USN in this paper, provides the u-IT agriculture to producer and the reliability about agricultural products. In addition, this system provides the foundation data to operate GAP and HACCP, and becomes the advantaged agricultural products of the interior of a country by application of this system.

Objectives: The aim of this study was to review the studies published over the last ten years on risk factors for suicidal ideation among the Korean elderly. Methods: A literature search was conducted using the major medical and health-related databases (PubMed, DBpia, RISS, KISS, KMbase, and National Assembly Library of Korea) with a set of keywords. A total of 41 articles published from 2000 to 2010 were selected for the review. The risk factors of suicidal ideation in the literature were categorized into physical, psychological, and social factor (life stressors and demographic factors). Their associations with suicidal ideation were reviewed and summarized. The instruments used to measure suicidal ideation were also examined. Results: Depression was the most significant risk factor for and a mediator of suicidal ideation among the Korean elderly. Demographic factors and self-reported health and their relationships with suicidal ideation were often examined, but the findings were inconsistent across studies. Stress level as well as family and social support were significant risk factors for suicidal ideation, while perceived economic status and actual income level were not. The Scale for Suicidal Ideation (SSI) and the Scale Suicidal Ideation Scale (SIS) were the two most widely used instruments, but they were modified in various ways across studies. Most existing studies on the topic of interest used cross-sectional and convenient samples. Conclusion: The existing studies support the need for early detection and management of depressive symptoms and stress, the key risk factors, to decrease suicidal ideation among the Korean elderly. Further studies with stronger research designs are necessary to obtain better evidence on whether physical health and social support can prevent suicidal ideation directly or by improving mental health. Necessary are consistent uses of measures for suicidal ideation across studies and further examination of cultural equivalence of the translated measures in Korean.

Pseudoxanthoma elasticum is a multiorgan disorder, characterized by ectopic mineralization of elastic fibers of skin, eyes, and cardiovascular system. The dermatologic manifestations include laxity of skin, as well as cutis laxa-like wrinkling especially on both axillae. The classic forms of pseudoxanthoma elasticum are due to mutations in the ATP-binding cassette subfamily C member 6 (ABCC6) gene, a presumed transmembrane transporter expressed primarily in the liver and the kidneys. Recent case reports of mutations of gamma-glutamyl carboxylase (GGCX) gene describe associations with vitamin K-dependent coagulation factor deficiency and pseudoxanthoma elasticum as well. A 23-year old woman presented with laxity on both axillae and trunk and a history of vitamin K-dependent coagulation factor deficiency, diagnosed 2 years ago. Fragmented and markedly degenerated elastic fibers with calcium deposition were identified on biopsy specimens. Herein, we report a case of autosomal recessive pseudoxanthoma elasticum combined with vitamin K-dependent coagulation factor deficiency. (Korean J Dermatol 2013;51(2):131∼134)

워크플로우는 컴퓨터에 의해서 자동으로 실행되고 관리되는 업무 프로세스이다. 워크플로우 기술은 기업 환경의 변화와 함께, 비즈니스 프로세스 관리(BPM:Business Process Management)의 개념과 함께 발전해 왔다. 또한 비즈니스를 수행하기 원하는 기업의 거래파트너간, 고객, 공급자들의 분리된 비즈니스 환경을 제거하고, 향상된 e-비즈니스를 수행하기 위한 통합 환경을 제공해주는 웹 서비스는 워크플로우를 구성하는 매우 중요한 개념이 되었고, 이러한 웹 서비스의 흐름을 정의하는 워크플로우 설계 언어가 많이 등장하였다. 그 중 가장 표준이 될 가능성이 유력한 BPEL4WS는 비즈니스 프로세스에 필요한 트랜잭션, 보상 등의 개념을 포함하여, 효율적으로 비즈니스 프로스세스를 구성할 수 있게 해 준다. 그러나 BPEL4WS는 1)고정된 WSDL파일을 참조하여, 그 흐름을 정적으로만 구성할 수 있다는 단점이 있고, 2)제한된 자원만을 갖고 있기 때문에, 의미를 부여할 수 없어 대체 서비스를 찾을 수 없다는 단점이 있다. 따라서 본 논문에서는 이러한 단점을 해결하기 위하여 기존의 WSDL에 의미(Semantic)을 부여하는 방법으로 이를 해결하고자 한다.

이 연구의 목적은 부정행위방지 검사 제작 시스템(Cheeting Proof Testing System: CPTS)을 설명하고 그 타당성을 검토하는 것이다. CPTS는 선택형 문항의 경우 선택지 순서를 시스템 내에서 임의로 변경함으로써 각각의 개별 피험자에게 개별화된 검사지를 제작하여 제공하는 컴퓨터 시스템이다. 즉, 개별화된 검사지를 받은 피험자는 같은 문항이라도 선택지의 순서와 위치가 다르기 때문에 다른 피험자의 시험지나 답안지를 보고 베끼는 부정행위를 할 수 없게 된다. CPTS의 타당성을 검토하기 위해 공변량 분석과 고전검사이론, 문항반응이론의 기법들이 사용되었다. 공변량 분석 결과 CPTS가 제공하는 개별화된 검사지를 시행한 실험집단과 피험자 모두 동일한 검사지를 시행한 통제집단 사이에 검사 점수에 있어서 통계적으로 유의미한 차이가 없는 것으로 나타났다. 고전검사이론과 문항반응이론을 이용한 문항 분석 결과, 문항난이도, 변별도와 같은 문항 특성 지수에 있어서 실험집단과 통제집단 사이에 유사한 결과를 산출하였고, 문항반응이론을 적용하여 산출한 검사특성곡선과 문항특성곡선도 유사하게 나타났다. 시험 감독교사와 참여했던 학생 피험자를 대상으로 한 설문 조사 결과, 감독 교사와 학생 모두 CPTS가 실제 검사 상황에서 학생들의 부정행위를 방지할 수 있는 효과적인 수단이 될 수 있을 것으로 인식하고 있었다. 결론적으로 CPTS는 검사특성 상 큰 변화는 일으키지 않으면서 선택형 문항 검사의 경우 학생들의 부정행위를 방지할 수 있는 하나의 방법으로 고려될 수 있을 것이다. The purpose of this study was to describe the Cheating Proof Testing System (CPTS), which was designed to prevent cheating on tests, and to evaluate its validity. The CPTS is a testing system that allows for the individualization of a test form given to an examinee by randomly arranging choice options. In this way, students taking the individualized test forms with randomly arranged choice options are discouraged from copying other students’ answers. To investigate the validity of the CPTS, several analyses were conducted utilizing both the analysis of covariance (ANCOVA) and classical test and item response theory approaches. The ANCOVA analysis revealed no significant differences between groups that either adopted or did not adopt the CPTS. Item characteristic indices such as item discrimination or item difficulty were similar in both CPTS tests and non-CPTS tests. Item and test characteristic curves were also very similar between the CPTS and non-CPTS tests. Survey research given to both teachers (or proctors) and students who have experienced the CPTS indicated that both teachers and students believed that the CPTS could be an effective way to prevent student cheating on tests. In conclusion, the CPTS should be considered a method to prevent student cheating without introducing significant psychometric changes in test characteristics.

Proliferative myositis is a rare, benign, probably pseudosarcomatous fibroblastic proliferation that typically presents as a rapidly growing soft tissue mass. Its relative rarity, fast growth rate, and unique histopathologic findings may lead to misdiagnosis as a malignant lesion and unnecessary radical surgical excision. A 57-year-old female presented with a non-tender, well-defined, indurated, solitary, hard papule on the median sulcus of the tongue for 2 weeks. Histologic examination revealed numerous fibroblastic or myofibroblastic spindle cells and large ganglion-like cells infiltrating between and around the muscle fascicles. Immunohistochemical staining showed positivity for vimentin, smooth muscle actin, and CD68 and negativity for S-100. Based on these characteristic clinical findings and histopathologic features, the patient was diagnosed with proliferative myositis. Here, we report a rare case of proliferative myositis on the tongue and recommend considering proliferative myositis in the differential diagnosis when a physician encounters a rapidly grown soft tissue mass.
