Purpose: To understand the essentials of rearing conflict experience by three shift nurses in advanced general hospitals. Methods: The design was a qualitative research of phenomenology. Participants were 7 shift nurses working in advanced general hospitals who were rearing young children. Data were collected individually through in-depth interview on their life experiences. Data were analyzed by Colaizzi’s phenomenological methodology. Results: Eighteen themes were drawn from 256 meaningful experiences and these themes were integrated to six theme clusters. The most influencing themes were ‘Regret that I cannot satisfy even the slightest wish’, ‘Fail to care for kids’, and ‘Mutual feeling to care giver between appreciation and inconvenience’. Other themes were as follows: ‘Body and mind are broken’, ‘The need for a three-shift system to support nurses who are rearing children’, ‘Doing my best for work and child rearing’. Conclusion: The nature of three-shift nurses working in advanced hospital and caring kids is explained as ‘lives with conflict’ between work and home. This study suggests it is necessary to establish a 24-hour care center for 3-shift nurses to keep working while rearing their children.

By using the concept of 'Resonance' in benzene which stems from a unit dealing with the carbocyclic compounds which is in a text 'Chemistry I', I developed teaching methods based on the history of science. This study was executed to analyze the effect by applying these methods. Seventy 3rd grade male students, who are attending a high school located in the Pohang area were used in this study. I investigated the level of the relative difficulty and the degree of scholastic achievement from each treatment group and controlled group using the concept of Resonance from the preceeding study. In this study, these 70 students divided into two classes- a traditional lecture group consisting of male 35 student, and a group using the history of chemistry consisting of the remaining 35 student and after a specified period, their scholastic achievement was analyzed. As a result of this study, the treatment group scored much higher (50.143) than the controlled group(25.429) in average score and showed significant difference between two groups. Through this study was based on the history of chemistry, after scientists let them realize the process of improving science attitude, and think like scientists, giving conceptual class can get much more efficiency and durability for learning. 본 연구는 화학 I 교과의 탄소 화합물 단원에서 벤젠의 '공명(共鳴)' 개념을 화학사에 기초한 교수 학습자료를 개발해 이를 이용한 수업과 전통적 강의식 수업과의 학습 효과를 비교, 분석할 목적으로 수행되었다. 연구 대상은 포항시에 소재한 일반계 고등학교 3학년 남학생 70명(2개 학반)이다. 선행 연구를 통하여 실험반과 통제반의 공명 개념 수업의 학업 성취도와 체감 난이도를 조사하였다. 본 연구에서, 전통적 강의식 수업 집단(35명)에게는 공명 개념의 변천 과정을 주입식으로 전달하였고, 화학사를 이용한 수업 집단(35명)에게는 화학사에 기초한 벤젠 구조와 공명 개념의 도출 과정을 학생들이 직접 경험하게 하였다. 두 집단 모두 학생 스스로가 개념 정리를 할 수 있는 시간을 동일하게 준 후, 학업 성취도를 분석하였다. 연구 결과, 실험 집단(50.143점)이 통제 집단(25.429점)보다 평균 점수가 높게 나타났으며, 그에 따른 유의미한 차이가 나타났다. 본 연구를 통하여 공명 개념 수업은 일방적인 강의식 수업보다는 화학사에 기초하여 과학자의 입장에서 생각하고 과학하는 과정을 깨닫게 한 후, 개념 수업을 하는 것이 학습의 효율성과 지속성에 효과가 더 크다.

This paper reports the results of the research on the effects of probiotic yogurt on the microbiological quality, pH, and sensorial characteristics of fresh chicken meat when packed with probiotic yogurt. The chicken meat pieces were packed with yogurt and were stored at $10^{\circ}C$ for 7 days. Samples were taken after 0, 2, 4, and 7 days of storage, and were analyzed for total bacterial count, E. coli, and coliform, and for the chemical parameters, including the pH. In the control group (packed without yogurt), the Pseudomonas species predominated when the spoilage was obvious after 4-day storage at $10^{\circ}C$. The yogurt-mixed chicken meat package was found to have a significantly lower total viable count and significantly fewer coliform bacteria during storage. Furthermore, the yogurt package showed a growth-inhibiting effect on the Salmonella typhimurium, which were inoculated into the chicken meat pieces for the study. The study findings indicate that probiotic yogurt can be used in packing fresh chicken meat to decrease the population of spoilage bacteria therein and to extend its shelf life.

국내산 해조류로부터 항혈전 제제의 개발을 위하여 해조류 열수추출물에 대하여 항응고 활성의 검색과정에서 높은 활성을 보였던 톳(Hizikia fusiforme)에서 항응고 활성 다당류를 분리, 정제하고 이 다당류의 화학적 특성과 항응고 활성 기작을 조사하였다. 분리, 정제는 톳(Hizikia fusiforme)의 열수추출물(HF-0)을 ethanol 농도별 침전을 실시한 결과 70% ethanol 온도에서 침전한 HF-2 획분이 가장 활성이 높았다. HF-2를 pronase와 periodate를 이용하여 단백질과 탄수화물을 선택 분해하여 활성을 비교한 결과 활성의 본체는 다당이었다. DEAE-Toyopearl 650C(Cl form)의 이온교환 크로마토그래프를 실시하여 5개의 획분으로 나누었으며 1.0M의 NaCl 농도에서 용출된 HF-2-3 획분이 가장 활성이 높았다. HF-2-3 획분을 Sephadex G-75(HF-2-3-1)와 Sepharose CL-6B(HF-2-3-1a)로 겔여과 크로마토그래피를 실시하여 최종적으로 정제된 다당류 HF-2-3-1a 획분을 얻어 그 순도를 GPC와 HPLC를 이용하여 확인하였다. 정제다당(HF-2-3-1a)의 분자량은 5.3×10^5 Da이었으며 주구성당은 fucose(51.92%), galactose(19.34%), mannose(13.92%), xylose(7.14%), arabinose(3.95%) 및 rhamnose(3.78%) 등으로 정제된 다당은 29.7%의 황산기를 함유하는 함황성 fucoidan이었다. HF-2-3-1a의 항응고 활성은 내인성 경로를 억제하며 fibrin 형성능을 측정한 결과 직접적으로 thrombin에 작용하지는 못하고 antithrombin Ⅲ의 활성을 증폭시켜 항응고 활성을 나타내며 농도 의존성 항응고 활성을 나타내었다. 톳 열수 추출물의 항응고 활성을 in vivo에서 측정한 결과 100㎎/㎏의 농도에서부터 활성이 나타나기 시작하여 250㎎/㎏의 농도에서는 100%의 항응고 활성이 나다났다. This study was focused on the purification, characterization and promotion mode of an anticoagulant polysaccharide from Hizikia fusiforme. The anticoagulant crude polysaccharide(HF-0) was obtained by using hot water extraction at 100℃ for 3 hrs after homogenizing desalted Hizikia fusiforme. The anticoagulant polysaccharide(HF-2-3-1a) was purified from the crude extract(HF-0) through stepwise gradient ethanol precipitation(HF-2), DEAE-Toyopearl 650C(HF-2-3), Sephadex G-75(HF-2-3-1), Sepharose CL-6B(HF-2-3-1a) chromatography and HPLC to homogeneity. HF-2-3-1a was estimated at 5.3×10^5 Da molecular weight and composed of fucose(51.92%), galactose(19.34%), mannose(13.92%), xylose(7.14%), arabinose(3.95%) and rhamnose(3.78%), and comprimised 29.7% sulfate residue. The sulfated anticoagulant polysaccharide from HF-2-3-1a was proposed to inhibit via the intrinsic pathway and common pathway in the blood coagulation. The HF-2-3-1a exhibited the anticoagulant activity by activating an antithrombin Ⅲ and the activity depended on the concentration of HF-2-3-1a. Acute toxicity of HF-2 in mice was not detected. Only 14 of 33 control mice(11.4%) that had taken saline survived for 30 min after injecting thrombin(100 NIH unit/ml).

심아밀로이드증의 궁극적 치료는 아밀로이드 침착의 병인에 달려 있으므로 증상치료와 함께 초기에 아밀로이드증의 원인을 밝히는 것이 무엇보다 중요하다. 강직성 척추염에서 AA형 아밀로이드증이 심장을 침범하는 경우는 흔치 않으며, 특히 본 증례는 동반질환인 MGUS와 연관된 AL형 심아밀로이드증이 심장 조직검사를 통해 함께 진단되어 치료를 시행한 경우로, 이와 같은 예는 국내 보고된 사례가 없어 저자들이 경험한 1예를 문헌고찰과 함께 보고한다. Amyloidosis is a clinical disorder caused by extracellular deposition of proteinaceous insoluble fibrils in various tissues, resulting in organ compromise. Amyloid L (AL) amyloidosis is the most common type of systemic amyloidosis, which occurs in association with multiple myeloma or monoclonal gammopathy of undetermined significance (MGUS). Secondary amyloid A (AA) amyloidosis is a complication of chronic inflammatory conditions, such as rheumatoid arthritis or ankylosing spondylitis. We report a case of a 49-year-old manwith a 11-year history of ankylosing spondylitis, who was recently diagnosed with MGUS presented with cardiac amyloidosis of both the AA and AL types. We report this case along with a review of relevant literature.
