본 연구에서는 컴퓨팅 사고력 평가 도구 중 자기보고식 설문과 지필형 검사지인 비버 챌린지 간의 상관관계를 분석하고자 하였다. 두 평가 도구를 사용한 결과 간의 상관관계는 통계적으로 유의하지 않았다. 따라서 객관적인 측정을 위하여 자기보고식 설문에 대한 수정 및 보완이 필요하며, 비버 챌린지의 점수에 영향을 주는 난이도에 대한 고찰이 필요하다. 덧붙여 산출물 평가와 자기보고식 설문, 지필형 검사지 간의 상관관계를 분석할 필요가 있다.

The purpose of this study is to develop and validate assessment tools and to analyze their applicability in problem solving programming education for college students of teacher training college. For this purpose, we have redefined the area of computational thinking and detail elements from the viewpoint of problem solving programming, and developed paper type inspection and self - report questionnaires to evaluate them. The reliability and validity were analyzed by applying the evaluation tool developed for the actual college students of teacher training college. Through this study, it was confirmed that the paper type inspection and self - report questionnaires developed in this study can be used as a tool to computational thinking assessment.

The most of discoid meniscus is located in lateral side. Medial discoid meniscus is rare. The medial discoid meniscus was reported by Cave and Staples at first in 1941 but rarely reported since then. A 8 year's old boy was diagnosed as having a complete medial discoid meniscus by means of MRI and arthroscopy. Authors performed the arthroscopic partial menisectomy for medial discoid meniscus. For confirmation of the bilaterality, arthroscopic examination on contralateral knee was performed but we did not find a medial discoid meniscus. We report 1 case of a medial discoid meniscus with a brief review of literatures.

Although the lateral discoid meniscus has been observed frequently, the medial discoid meniscus is an extremely rare anomaly. The incidence of lateral discoid menisci ranges from 1.4% to 15.5% and the incidence of medial discoid menisci ranges from 0.06% to 0.3%. We present 1 patient of bilateral medial discoid menisci with tear on left side and 1 patient of unilateral medial discoid meniscus with tear, that were diagnosed by magnetic resonance imaging (MRI) and arthroscopy. We performed partial meniscectomy on 2 cases of symptomatic medial discoid menisci under arthroscopy and meniscus-related symptoms were relieved. We report 3 cases of 2 patients with medial discoid meniscus.

A discoid medial meniscus is a relatively rare pathology of the knee joint, and we recently encountered a patient with discoid medial meniscus, and this report is a case of therapeutic experience in this patient. The patient was twenty years old man who had a persistent dull pain for several years without specific trauma history. He was presumptively diagnosed as discoid medial meniscus by MRI, and arthroscopic examination confirmed the presence of the complete type of discoid medial meniscus with horizontal tear. We performed arthroscopic partial meniscectomy, and the patient could get free from symptom.

The meniscal cyst of knee joint is a rare disease, and the discoid meniscal cyst has not been reported in Korea. We report 3 cases of the discoid meniscal cyst confirmed by MRI and arthroscopy. In physical examination, all cases have tenderness of the knee joint. One has palpable mass of knee joint and the other one has limitation of knee motion with knee flexion contracture of 10 degrees and positive McMurray test at external rotation of the knee. All cases are complete discoid meniscus, which are, one medial discoid meniscus and two lateral discoid meniscus through MRI. We confirmed horizontal tear of meniscus in all cases and the location of meniscal cysts are anterior hem of meniscus in one and body of meniscus in two. We could get excellent results in all 3 cases that return to normal knee range of motion.

The lateral meniscus is morphologically more variable than the medial meniscus. An abnormal lateral meniscus also varies with respect to its size, shape and stability, and such variations can occur in any patient of any age. The most common variant is a discoid lateral meniscus. We recently encountered a patient with a discoid lateral meniscus for which the anterior horn of the meniscus was anomalously inserted into the anterior ACL. The patient was forty five years old women who had persistent pain for three to four years without any specific trauma history. She was preoperatively diagnosed as having discoid lateral meniscus by MRI, and was confirmed the presence of the complex tear and anomalous insertion of the anterior horn of the discoid lateral meniscus into the anterior ACL by arthroscopic examination. Arthroscopic subtotal meniscectomy was performed and the symptoms were improved after surgery.

Most of bucket handle meniscal tears are associated with anterior cruciate ligament (ACL) deficiency. Lateral meniscus lesions are more common with acute ACL deficiency, where medial meniscus lesions are more associated with chronic ACL deficiency. We reported an ACL deficient knee with bucket handle tears of medial and lateral meniscus of the same knee. The report suggests the need for increased awareness of the possible presence of this. Additionally, we discuss injury mechanism, clinical symptoms, specific signs on Magnetic Resonance Imaging (MRI), and treatment options.

Rupture of the adductor longus muscle of the thigh is a rare muscular injury. It is produced by several causes, such as trauma. Ultrasonography and magnetic resonance imaging need to differential diagnosis to other disease. Successful results by conservative management, surgical repair is indicated in the fresh rupture. 18-year-old, 17-year-old, and 20-year-old male patient were diagnosed as having a adductor longus rupture by means of physical examination, ultrasonography, and magnetic resonance imaging. One patient was treated by physical treatment, the other patients were treated by surgical excision. We report three cases of adductor longus rupture with a brief review of literature.

The purpose of this study is to examine the effects of a singing program on withdrawal behaviors of children in low-income families. To measure the effects of the singing program, the researcher compared the results of K-YSR and TRF withdrawal scales before and after the program. Finally, the researcher did research on the subjects' musical and non-musical behaviors related to withdrawal through a record of behavior observation. The results of this study were asfollows: First, after comparing the results of K-YSR and TRF withdrawal scales conducted before and after the singing program, the mean of the scores was decreased by 6.4 and 3.6 points respectively (p = .042). Second, an analysis of withdrawal-related behavioral changes in music activities after the program showed an increase in frequency of eye contact, as well as tone and volume of subjects' voices. The results of this study indicate that the singing program has positive effects on withdrawal behaviors of children in low-income familiesin addition, it is effective in alleviating withdrawal-related behaviors.
