최근 국내 erythromycin 내성률이 증가하는 추세임을 보고하였고 erythromycin의 경우 내성의 증가는 항생제 사용량의 증가와 일치하고 있음을 보고하였다. 그래서 macrolide에 의한 내성균주의 확산을 막고 임상에서 보고되는 penicillin에 의한 치료 실패를 줄이기 위해 A군 연쇄구균 치료에 제일차 약물로 cephalosporin을 고려할 수 있다. Cefdinir의 A군 연쇄구균에 대한 항균력과 인두 편도염에 대한 우수한 임상효과 및 높은 안전성을 미루어 볼 때, Cefdinir는 A군 연쇄구균에 의한 소아 인두 편도염에 유효한 항생제로 사용될 수 있다. Objective : To determine the clinical and bacteriologic efficacy and safety of Cefdinir in acute pharyngitis and pharyngotonsillitis caused by group A beta hemolytic streptococci in pediatric patients. Methods : Children aged 3 through 12 years who visited the hospitals enrolled in this study with signs and symptoms of pharyngitis or pharyngotonsillitis since May to December 2002, were taken throat culture and given Cefdinir(12 mg/kg/day, in three divided doses) for 7 days. Two hundred thirty five patients were enrolled and 90 patients who showed positive culture results were followed up for the signs and symptoms during the treatment to determine clinical efficacy. Follow-up culture were done at the end of the study and bacteriologic efficacy was determined Results : Ninety out of 235 patients who visited the hospitals with the signs and symptoms of pharyngitis showed positive growth on throat culture. Seventy nine patients were clinically and microbiologically assessable. The bacteriologic eradication rates of S. pyogenes were 100% in all the children treated with Cefdinir. Clinical cure rates were not different between less than 7 days-treated group(75%) and just 7 days-treated group(98.6%)(P=0.077). Two patients reported adverse reaction during Cefdinir treatment. Antimicrobial sensitivity of Cefdinir against S. pyogenes was 100% with range of MIC being less than 0.5 ${\mu}g/mL$. Conclusion : It seems that Cefdinir is one of reliable and well-tolerated drugs for the treatment of group A beta hemolytic streptococcal pharyngotonsillitis in children. It needs to be investigated short term efficacy in terms of improving drug compliance and impact of economic point of view. We can recognized that still high rate of the erythromycin resistant group A streptococci in our community should be monitored every year.

정지영,문순정,조병수,차성호,이희주,Chung, Ji-Young,Moon, Soon-Chung,Cho, Byoung-Su,Cha, Seong-Ho,Lee, Hee-Joo 대한소아감염학회 2002 Pediatric Infection and Vaccine Vol.9 No.1
Streptococcus milleri Group Bacteria(SMG)는 인간의 정상 세균총이면서 농양 형성을 잘 하는 병원균으로도 작용하지만 그 병원성에 대해서는 잘 알려져 있지 않다. 따라서 SMG 감염시 경각심을 갖고, 적절한 치료에도 증상이 지속될 때에는 병변 이외의 다른 곳에 농양이 형성되어 있는지 반드시 살펴보아야 한다. Streptococcus milleri Goup Bacteria(SMG) comprise three species, Streptococcus anginosus, Streptococcus intermedius, Streptococcus constellatus. Although they are commensal organism, they can be pathogenic. SMG can be aggressive pathogen in the head and neck with a propensity for abscess formation and local extension of the infection. SMG is culturally and biochemically variable, which makes it hard for the clinicians to recognize it. Hence, it seems that this organism has been relatively neglected. Most of the Lancefield F streptococci are SMG. We report one patient who had Group F streptococcal bacteremia and subdural abscess. According to his medical history, he was diagnosed as membranoproliperative glomerulonephritis three years ago. He complained headache although he was treated by appropiate antibiotics. Brain CT was used as a tool to identify the brain abscess. He had surgical drainage and was treated with IV antibiotics postoperatively.

OTT 플랫폼의 스포츠 콘텐츠 서비스 특성이 충성도 및 지속사용의도에 미치는 영향 : 만족도 매개효과
정지영(Chung, Ji-Young),황동규(Hwang, Dong-Kyu) 한국체육과학회 2023 한국체육과학회지 Vol.32 No.3
The purpose of this study is to investigate the mediating effect of satisfaction on the relationship between the characteristics of sports content service on OTT platforms and loyalty and intention to continue using the service. An online survey link was distributed to individuals who had used OTT platforms for sports content services from March 4 to 14, 2023. Out of the 335 respondents, 313 were included in the final analysis after excluding those who provided unreliable or incomplete responses on 22 survey. The collected data were analyzed using frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis, multiple regression analysis, and mediation analysis using the Process Macro. First, the characteristics of sports content service on OTT platforms (usefulness, information quality, and service quality) had a significant impact on loyalty and intention to continue using the service. Second, the mediating effect of satisfaction was verified in the relationship between the characteristics of sports content service on OTT platforms and loyalty and intention to continue using the service, with satisfaction partially mediating the relationship between the characteristics of sports content service on OTT platforms and loyalty and intention to continue using the service. This study aims to establish a theoretical and practical basis for further research by examining the mediating effect of satisfaction on the relationship between the characteristics of sports content service on OTT platforms and loyalty and intention to continue using the service.

The purpose of this study is to provide some architectural characteristics of recycled school facilities. To achieve this purpose literature review and case study are performed. In addition this study research the sphere of recycling abolished school facilities and the transformation of space. Because the abolished school is recycling with mostly new functions, composition of the space has to be consisted in order to perform the function sufficiently. Techniques and plans by renovation method must be searched to express the part of new function and characteristic.

단감빵을 개발하기 위하여 강력분을 단감가루로 대체할 수 있는 적정 비율을 결정하고, 단감가루 대체 비율별 단감빵의 물리적, 관능적 검사를 통하여 단감빵의 품질 특성을 살펴본 결과는 다음과 같다. 강력분 대신 단감가루를 5, 10, 15, 20% 대체했을 때 단감가루의 비율이 증가함에 따라 수분 흡수율과 빵의 부피는 감소하고 빵의 무게는 증가하였다. 식이섬유나 비타민 A, β-카로틴, 비타민 C 함량은 밀빵보다 단감빵에 훨씬 많았으며 단감가루 대체율이 증가할수록 증가하였다. 색도는 단감가루의 비율이 증가할수록 빵 껍질색에서 L, b값은 감소하였지만 a값은 증가하였고, 빵 내부색에서는 L값만 감소하고 a, b값은 증가하였다. 기호도 검사에서 외관을 제외한 풍미, 조직감, 전반적인 기호도에서는 10% 단감빵이 밀빵보다 선호되었고, 맛에서는 5% 단감빵이 가장 점수가 높았고, 10% 단감빵이 그 다음으로 나타났다. 관능검사 QDA 결과 단감가루 대체 비율이 증가할수록 껍질색, 내부색, 단감향, 갈변취, 단맛, 뒷맛, 탄력성, 점착성은 증가하였다. 단단함은 단감빵보다 밀빵이 높은 반면 촉촉함은 단감빵이 높았다. 전반적인 기호도는 단감가루를 10% 대체한 경우가 가장 높고 그 다음이 5% 대체한 단감빵, 대조구 밀빵 순으로, 대조구 밀빵보다 단감빵의 기호도가 좋다고 평가되었다. To develop sweet persimmon bread, the proper ratio of the sweet persimmon powder substituted for strong flour was decided. When 5%, 10%, 15% and 20% of sweet persimmon powder was substituted as much amount of strong flour, the ratio of moisture absorption and loaf volume decreased while its weight increased. The contents of vitamin A, β-carotene and vitamin C increased as the substitute ratio of sweet persimmon powder increased. In color values, as sweet persimmon powder was added more, L and b values decreased and a value increased in the crust while in the crumb bread L value decreased and a, b values increased. In the sensory evaluation, the bread added with 10% persimmon powder was preferred to control in flavor, texture and overall acceptability but not in appearance.

마늘종의 조리법으로 빈번이 사용되고 있는 데치기, 볶음처리, 간장 절임 마늘종장아찌, 고추장 절임 마늘종장아찌를 선택하여 마늘종을 조리한 후에 항산화관련 물질의 함량과 항산화 효능을 생마늘종과 비교 측정하여 마늘종을 활용한 응용식품 개발에 기초자료를 제공하고자 하였다. 생마늘종은 생마늘에 비해 알리신이나 페놀화합물 함량이 낮게 함유되었으나 클로로필, β-카로틴, 비타민 C는 현저히 높은 것으로 나타났다. 조리 후 마늘종에 함유된 클로로필과 β-카로틴 함량은 증가하였으나 비타민 C, 페놀화합물, 알리신 함량은 감소하였다. 측정된 항산화 효능은 생마늘이 EDA와 NSA가 생마늘종에 비해 현저히 높았으나 SOD는 유의적으로 낮았다. 조리 후 마늘종의 항산화 효능은 감소하여 생마늘종, 볶음 처리, 데치기, 간장 절임 마늘종장아찌, 고추장절임 마늘종장아찌 순으로 낮아졌다. 조리 후에도 마늘종의 EDA와 NSA는 마늘보다 낮게 나타났으나, 생것에 비해 그 차이가 적어져 EDA는 마늘의 약 70%, NSA는 약 65% 정도였으며, SOD 유사활성은 마늘과 유사하였다. 조리 전, 후에 나타난 항산화 효능은 한지형이 난지형보다 높았다. 따라서 항산화 효능 면에서 마늘종을 생으로 먹는 것이 가장 좋고, 기호에 따라 단시간 볶거나 데친 후에도 상당한 항산화 효능을 가지는 것으로 나타나 이를 더욱 다양하게 이용할 수 있는 방안들도 추후 연구되어져야 할 것이다. Antioxidant compounds and activities of raw and cooked (blanching, pan-frying, soy sauce pickle, Kochugang pickle) domestic garlic stems were investigated. The contents of chlorophyll, carotenoid, vitamin C, phenolic compounds and allicin in raw and cooked garlic stems were measured. Various cooking process increased significantly chlorophyll and β-carotene contents of garlic stem, but decreased vitamin C, phenolic compounds and allicin contents (p<0.05). Antioxidant activities of methanol extracts from raw and cooked garlic stem such as electronic donating ability (EDA), superoxide dismutase (SOD)-like activity and nitrite scavenging ability (NSA) were compared. The antioxidant activities were found to have lowered in the order of raw> pan-frying> blanching> garlic stem soy sauce pickle> garlic stem Kochujang pickle. Antioxidant activities of cooked garlic stems were more than 65% of cooked garlic bulbs.
