연쇄알구균에 의한 급성 인후염 후 발생한 반응성 관절염은 급성 류마티스열의 개정된 진단기준을 충족하지 못하면서, 지속적 혹은 재발성의 비이동성 관절염과 발열, 홍반성 결절, 일시적 간기능 이상 등을 보이면서 심장염과 무도증을 드물게 동반하는 질환이다. 따라서, 발열을 동반한 급성 관절염 환자에서 감별해야 할 질환 중의 하나이며, 심근염 예방을 위한 페니실린 요법의 적응증 및 기간에 대해서는 아직 이론이 많은 상황으로, 보다 광범위한 연구가 필요하다. 저자들은 연쇄알구균에 의한 급성 인후염 1주 후에 발생한 하지의 다발성 비이동성 관절염과 함께 결절홍반 및 일시적 간기능 이상을 보인 환자에서 PSRA로 진단하고 비스테로이드성 항염증제 및 스테로이드로 성공적인 치료를 하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Poststreptococcal reactive arthritis (PSRA) is associated with recent streptococcal infections. However, PSRA is distinct from acute rheumatic fever by its clinical manifestations: non-migrating arthritis, erythema nodosum or erythema multiforme, and transient elevation of serum transaminases. We experienced a 33-year-old man who presented with fever, arthritis of both knees and ankles, and erythema nodosums on extensor surfaces of lower legs which developed 6 days after the onset of pharyngitis symptoms. Blood and urine cultures were negative. Throat culture was negative for group A β-hemolytic streptococcus. The ASO titers increased up to 2080 IU/mL in sequential monitoring. The result of bone scan was compatible to arthritis of both knees and ankles. There were no signs or symptom of carditis. He showed clinical improvement with anti-inflammatory drugs (naproxen 1,000 mg/day and prednisolone 7.5 mg/d). PSRA should be included in the differential diagnosis of patients presenting with arthritis combined with fever.

씨감자를 사용할 때 발생하는 수량감소는 씨감자의 퇴화에 그 원인이 있는데 이는 PLRV, PVY와 같은 virus 감염에 의한 병리적 원인, 비정상적인 물질대사에 의해 강엽 내 성분량의 변화가 씨감자의 생산력을 저하시키는 생리적 원인 및 기상조건과 같은 환경요인이 주로 관여한다. 이에 따라 생장점 배양에 의해 무병주를 획득하고 이를 기내에서 대량으로 증식시킨 후 격리 온실에서 씨감자를 생산하는 방법이 널리 이용되고 있고 기내 괴경형성에 대한 실험도 많이 이루어지고 있다. 기내에서의 shoot 증식에는 여러 가지 생장조절물질, 특히 kinetin, BAP, zeatin등이 효과적으로 이용되며 shoot로 부터의 기내 소괴경의 유도는 배지 내 당 농도의 증가, ancimidol과 같은 생장억제제, 암 배양이나 단일조건의 부여에 의해 쉽게 이루어진다. 기내 줄기의 삽목 증식 후 이를 노지에 이식하여 소괴경을 형성시키는 방법의 경우, 현재까지는 주로 배지조건에 치중하여 왔으며 광 조건, 온도, 배양용기의 환기 등에 관한 연구는 많이 되어 있지 않은 상태이다. 따라서 노지에서의 순화율 및 이후의 생장 저하 등 많은 문제점이 발생하고 있다. 또한 한정된 크기의 배양용기를 이용함에 따라 신초의 길이 생장이 억제되고 이에 따라 마디의 수도 감소하여 증식 효율이 낮아지게 된다. 따라서 포장에서의 원활한 순화와 식물체 생율을 위해서는 배양환경, 즉 광도, 광 주기, 배양용기의 환기방안, 기내 광합성 유도 등에 대한 연구와 함께 새로운 배양용기의 개발이 필요하다. 한편, 기내 괴경을 이용한 씨감자 생산은 시간, 노동력 및 생산비용이 많이 소요되는 것에 비해 생산 효율은 높지 않은 등 여러 문제점들이 지적되고 있다 .최근 많이 연구되고 있는 양액 재배에 의한 무병 종서 생산은 기내 소 괴경 이용 방식에 비해 괴경 크기가 크고 식물체 당 괴경 수가 월등히 많아 직접 씨감자로 이용할 수 있는 장점을 가지고 있다. 본 실험에서는 생물 반응기에서의 배양 방식이 감자 shoot의 기내 생장에 미치는 영향과 양액 재배 시스템에 따른 식물체 생육 및 괴경 형성 정도를 비교하였다.

This study aimed to provide useful information by investigating the relationships between the results of teacher evaluation for professional development, teachers’ demographic characteristics, and their perception of expertise. Among those who participated in the survey asking teachers’ perception of the 2014 teacher evaluation for professional development, the data from 1,622 teachers in the upper and lower limits of one standard deviation of teacher peer evaluation and student satisfaction were used. Study findings were as follows. First, statistically significant and positive correlations existed between teacher evaluation results and teachers’perception of expertise. Second, female teachers, those whose career spanned 5-15 years, elementary teachers perceived their expertise higher than those of male teachers, those whose careers did not span 5-15 years, and middle and high school teachers. Third, mean scores of expertise perception of teachers who had high scores on peer evaluation and student satisfaction were higher than those of other groups. Last, providing information to parents and appropriate evaluation were the key factors distinguishing those who had high scores on teacher evaluation and student satisfaction from those had high scores on teacher evaluation and low scores on student satisfaction. In addition, providing information to parents was the key factor differentiating those who had high scores on teacher evaluation and student satisfaction from those who had low scores on both teacher evaluation and student satisfaction. The significance of these study results was discussed along with limitations and suggestions for future research studies.

우수한 심미성 수복재료로서 복합레진은 그 사용 빈도가 증가하고 있다. 이런 증가 추세에도 불구하고 복합레진의 부적절한 마모저항성 때문에 구치부 수복에서의 사용이 제한되어왔다. 이와 관련된 인자로 수복물의 표면하 분해가 고려되고 있다. 본 연구에서는 복합레진의 마모에 미치는 환경적 분해의 효과를 알기 위해 알카리성 용액(0.1 N NaOH)에 현재 많이 사용되는 Definite(Degussa-Hu¨ls AG, Germany), Prodigy(Kerr, USA), Pyramid(Bisco, USA) 및 Synergy(Coltene, Swiss)등 4종의 복합레진을 보관하였을 때 각 제품의 분해과정을 평가하고자 하였다. 각 제품 당 3개의 시편을 제작한 후 0.1N NaOH 용액에 저장하여 60℃에서 보관하였다. 2주 후 제거하여 HCI로 중화, 세척 후 60℃에서 건조하였다. 무게 손실, 분해층 깊이, Si 농도 등을 기준으로 분해저항성을 평가하여 다음과 같은 결과를 얻었다. 1. 무게 손실은 Synergy에서 1.24±0.002%로 가장 높은 값을 보였으나 각 제품간 유의한 차이는 보이지 않았다. 2. 분해층 깊이는 Synergy에서 107.83±2.52㎛로 가장 높은 값을 보였고, Synergy를 제외한 다른 제품에서는 유의한 차이를 보이지 않았다. 3. Si 용출량에 있어서는 4가지 제품 모두 차이를 보이지 않았다. 4. 무게 손실과 분해층 깊이 사이에는 높은 상관 관계를 보였다(r=0.6127, p<0.05). 5. 무게 손실과 Si 용출량, 분해층 깊이와 Si 용출량 사이에 상관 관계는 없는 것으로 나타났다. 6. 주사전자현미경 관찰시 NaOH 용액에 보관한 후 레진 기질과 필러 사이의 결합 파괴를 관찰할 수 있었다. The use of resin composites has continued to increase over the last several years. In spite of their growing popularity, composites continue to exhibit a number of undesirable characteristics. One of the major deficiencies of composite restorative resins is their inadequate resistance to wear. Of the multitude of factors that have been associated with wear, subsurface degradation within the restoration is considered to be one. The aim of this study was to evaluate the resistance to degradation of four commercial composite resins in an alkaline solution. This solution with a high concentration of hydroxyl ions is a convenient medium for accelerated degradation of silane coupling and filler particles. The brands studies were Definite(Degussa-Hu¨ls AG, Germany), Prodigy(Kerr, USA), Pyramid(Bisco, USA) and Synergy(Coltene, Swiss). Preweighed discs of each brand were exposed to 0.1N NaOH solution at 60℃. After 14 days they were removed, neutralized with HCI, washed with water and dried. Resistance to degradation was evaluated on the basis of following parameters: (a) mass loss(%)-determined from pre-and post-exposed specimen weights; (b) Si loss(ppm)-obtained from ICP-AE analysis of solution exposed to specimens; and (c) degradation depth(㎛)-measured microscopically (SEM) from polished circular sections of exposed specimens. The results were follows: 1. Mass loss of Synergy was 1.24±0.002%. it was the highest, there was no significant difference among the materials. 2. The degree of degradation layer depth of Synergy was 107.83±2.52㎛, it was the highest, there was no significant difference among any other materials than Synergy. 3. There was no difference among the four materials in Si loss. 4. The correlation coefficient between mass loss and degradation depth was relatively high(r=0.06, p<0.05). 5. There was no coefficient correlation between Si loss and mass loss, the degree of degradation layer depth and Si loss. 6. When observed with SEM, destruction of bonding is observed between resin matrix and filler.

The purposes of this study were: (1) to investigate the relation of 4 aspects of clothing behavior to locus of control, (2) to ascertain whether differences exist between males and females on clothing behaviors, and (3) to develop measures of attitudes toward Korean traditional clothing and clothing appropriateness. Locus of control was assessed by Rotter's Internal-External Locus of Control Scale as modified by Jeho Cha and others. The existing clothing interest measures were slightly modified to assess interest in fashion, modesty and clothing importance. Additional measures of attitudes toward Korean traditional clothing (Ⅰ)&(Ⅱ), clothing appropriateness, and attitudes toward the latest male and female fashion styles were developed. The sample consisted of 627 male and 453 female students in Yonsei University in Seoul, Korea. The data were collected by means of self-administered questionnaires and were analyzed by correlation, Z-tests, and X^2 tests. The results indicated that: 1) Locus of control was significantly related to attitudes toward Korean traditional clothing (Ⅰ)&(Ⅱ), fashion interest, and 2 aspects of clothing appropriateness: those who were high on internal reinforcement had more positive attitudes to various aspects of Korean traditional clothing and they also accepted more varied male outfits for campus wear. They also considered Korean clothing as more suitable to more varied social occasions. On the other hand, those who were high on external reinforcement were more interested in fashion. 2) As for sex differences on clothing behavior, females scored significantly higher on interest in fashion, modesty, and clothing importance. Compared with males they preferred the latest fashion style of clothing for both sexes. There were no significant differences between males and females on clothing appropriateness scores and attitudes toward Korean traditional clothing. 3) Attitudes toward Korean traditional clothing were related negatively to fashion interest, whereas it was related positively to modesty in clothing. 4) Fashion interest was related positively to clothing importance and negatively to modesty in clothing. 5) The measures developed for this study had high reliability, thus, these could be of use for further clothing behavior studies.
