There exists a major impediment to learning electricity which may illuminate why direct presentation of scientists' ideas is too aggressive a strategy. This impediment lies in thinking that electricity is used up and in envisaging the light bulb as a consumer. This view is based on a powerful idea which summarises much of our experience; it declares that 'things get used up', 'you cannot get something for nothing', and 'intuitive thinking'. To replace this view with scientific view, we made the analogy model. It is suggested that the analogy model is more effective in teaching electricity circuits than conventional teaching method.

Public libraries need to raise their quality of reference service to a higher degree by answering from the questions in order to make a contribution as a social service institution. Therefore, in this study, the present situation and users' recognition level about reference service were analyzed according to age groups of public libraries in Pusan. The purpose of this study is to build a framework for improving the system and planning and performing the service of public libraries. To achieve this goal, a theoretical approach was tried through the previous studies and the verification study was performed with the subject of the 487 users who are using the 16 public libraries in Pusan.

CIDI-Alcohol의 한국어 판 개발을 위해 이를 우리말로 번역, 수정하고, 정신병원에 입원한 환자 90명과 일반인 50명에게 시행한 후 임상 진단과 비교하여 일치도를 봄으로써 그 신뢰도 및 타당도를 조사하였다. 결과는 다음과 같다. 1) 주정 사용 각 진단 범주에 대한 한국어 판 CIDI-Alcohol의 일반 면담자간 진단 일치도는 97%∼100%의 높은 일치도를 보였다. 2) 임상 진단을 기준으로 한 한국어 판CIDI-Alcohol의 주정 사용 장애의 진단 일치도는 각 진단 범주별로 kappa치가 0.43∼0.55로 기존의 연구에 비해 비교적 낮았다. 3) CIDI-Alcohol의 진단 기준을 변화시켜, 각 진단 범주에 대한 임상 진단과의 일치도를 알아본 결과 ICD-10/harmful use는 진단 기준 항목의 수를 2개 이상으로 하였을 때, DSM-Ⅲ-R/주정 의존은 진단 기준 항목의 수를 4개 이상으로 하였을 때 임상 진단과 가장 일치하였다. 이런 결과는 한국어 판 CIDI-Alcohol의 진단 기준이 대체적으로 민감도는 높으나, 특이도가 떨어지는 것으로 생각할 수 있으며, 따라서 본 연구자들에 의해 작성된 한국어 판 CIDI-Alcohol는 일반인구 집단을 대상으로 하는 역학 조사보다는 주정 사용 장애로 이루어진 순수한 실험군의 연구에 적합하다고 생각된다. he authors translated a CIDI-Alcohol, a highly structured diagnostic interview, into Korean and examined the validity and reliability of the Korean version of CIDI-Alcohol. In order to examine the validity and reliability of CIDI-Alcohol, the authors calculated the degree of agreement of CIDI-Alcohol diagnoses between the two lay interviewers and sensitivity, specificity, kappa coefficient between clinical and lay CIDI-Alcohol diagnoses. The results were as follows: 1) Agreement rates of CIDI-Alcohol diagnoses between the two lay interviewers ranged from 97% to 100%. The kappa coefficient for each diagnosis was quite high(0.96-1.0). 2) The kappa value of agreement between clinical and lay CIDI-Alcohol diagnoses ranged from 0.43 to 0.55, which was lower than those of other studies. 3) With canging the diagnostic criteria of CIDI-Alcohol, The highest agreement rate between clinical and CIDI-Alcohol diagnoses was acquired when the authors used two or more diagnostic criteria of ICD-10/harmful use and four or more diagnostic criteria of DSM-Ⅲ-R/ alcohol dependence.

The effects of flesh color, season, and test cross on carotenoid, sugar, and ascorbic acid contents of 20watermelon genotypes with red, pink, orange, and yellow flesh were examined. Red- and pink-fleshed watermelons contained lycopene (4.8-47.8 μg・g-1 fresh weight), β-carotene (< 3.7 μg・g-1), and lutein (< 0.9 μg・g-1) as the major carotenoids. The orange and yellow watermelons contained complex mixtures of prolycopene, lycopene, and β-carotene with levels less than 7.4, 1.5, and 8.5 μg・g-1, respectively. There were also minor carotenoids, such as violaxanthin,lutein, neurosporene, and zeacarotene in the range of 0-1.4 μg・g-1. Total sugar contents ranged from 24 to 91 mg・g-1,with sucrose, glucose, and fructose as the major sugars. The sugar profiles were divided into sucrose-, fructose-, and non-dominant groups. Higher percentages of glucose and fructose were negatively correlated with the total sugar content. Fairly-low levels of ascorbic acid, less than 28.2 μg・g-1, were measured, and some genotypes had nearly no ascorbic acid. There were only slight differences in ascorbic acid, sugar, soluble-solid, and total-carotenoid contents among 11 genotypes harvested in June and November. Five sets of test crosses showed various trends of heritability of carotenoids, sugars, and ascorbic acid in F1 hybrids. In general, carotenoids and total sugar content tended to be inherited from the parent with lower carotenoid and sugar contents, respectively. Paralleled chemical analyses will be beneficial for efficient progress in breeding efforts and genetic research.

Plant pigments such as anthocyanins and carotenoids have been shown to be benefi cial to human health. Therefore, carrotlines of diff erent colors have been recently developed. This study aimed to characterize terpenoid, carotene, anthocyanin,and soluble solids content and antioxidant activity levels in orange, yellow, black, and purple carrots to develop new colorcarrot cultivars with more nutrients, health benefi ts, and consumer acceptance. Both individual and total terpenoid contentgreatly varied among breeding lines. Each line had a unique composition, and there was no general pattern between color andterpenoid content. Orange carrot roots had high levels of α-carotene, β-carotene, and total carotenoids compared with yellow. Red carrots were characterized by high lycopene content, and black carrots exhibited identical levels of lycopene content toyellow carrots. Leaf tissues contained lutein as the main carotenoid followed by β-carotene. There was no clear relationshipbetween leaf and root carotene profi les and content. Black and purple root colors were determined by composition and amountof anthocyanin compounds, and about fi ve major compounds were detected in this study. Total anthocyanin content was highin solid black carrots and decreased as the interior root color contained more yellow, with low and trace levels in purple andorange carrots, respectively. Soluble solid content ranged between 4.0 and 9.5 °Brix among lines. Anthocyanin content washighly correlated with antioxidant activity. Each color of carrot contained diff erent levels of the tested compounds and mayrequire extensive breeding to obtain desired levels.
Pathological Fracture of the Femoral Neck due to Tophaceous Gout: An Unusual Case of Gout
Yoo-Sun Jeon,황득수,황정모,Jeong-Kil Lee,박용철 대한고관절학회 2019 Hip and Pelvis Vol.31 No.4
A 48-year-old man visited the emergency room with right hip pain that started abruptly while walking out of the bathroom. Computed tomography showed an intraosseous mass in the femoral neck. The patient had a 15-year history of gout and had numerous bilateral tophi in his hands, feet, knees, and elbows. After operation, we diagnosed a pathological fracture due to intraosseous tophi. Patients with hip pain who have many subcutaneous tophi and long-standing gout should be diagnosed carefully. Peri-hip joint pain caused by gout is uncommon, however, if a patient complains of pain, a simple X-ray may be required. If intraosseous tophi are present, appropriate treatment (e.g., strict hyperuricemia control with or without prophylactic internal fixation), may be required before fracture occurs.

40명의 만성정신분열증 환자를 대상으로 Haloperdiol에 대한 Cyproheptadine 병용치료 효과를 검증하기 위하여 6주간의 위약-대조, 이중맹검 연구를 시행하였다. 6주간의 이중맹검 Cyproheptadine 병용치료는 양성 및 음성증상 모두에서 임상적인 증상의 호전을 보였으나 위약과 Haloperidol 이 병용 투여된 대조군과 비교한 임상적 정신증상에서는 두군 간의 유의한 통계적 차이는 보이지 않았다. 그러나 Cyproheptadine 병용치료는 대조군에 비해 추체외로 증상의 유의한 감소를 보임으로써 항정신병 약물의 비정형적인 특성이 있음을 지지해주고 있다. 신경 내분비학적 검사에서는 Cyproheptadine 병용치료가 혈청내 prolactine치를 감소시키지는 않았으나 혈청내 cortisol 치를 유의하게 감소시켰다. 비록 보다 장기간의 추적 연구가 필요하겠으나 본 연구의 결과는 Cyproheptadine 병용치료가 기존전형적인 항정신병 약물로 인한 추체외로 부작용으로 지속적인 약물치료가 힘든 만성정신분열증 환자의 치료에 효과적일 수 있음을 제시한다.
