범부채 (Belamcanda chinensis)의 기내 식물체 재분화 체계를 확립하기 위하여, 생장조절물질이 자엽, 뿌리줄기, 뿌리 절편체로부터 캘러스 유도와 식물체 재분화에 미치는 영향을 조사하였다. 조직별 캘러스 유도율은 자엽절 편체 보다 뿌리절편체에서 더 왕성하게 관찰되었으며, 3.0 mg/L 2,4-D의 단독처리와 1.0 mg/L 2,4-D와 3.0 mg/L BA의 혼합처리에서 캘러스가 가장 효과적으로 유도되었다. 또한, 3.0 mg/L 2,4-D를 단독처리 한 배지에서 유도된 캘러스를 치상하여 4주간 배양하였을 때 가장 많은 신초가 유도되었으며, BA를 혼합 처리한 배지에서는 다발성 신초가 유도되었고 신초의 생장이 양호하였다. 2,4-D와 BA를 혼합처리 한 배지로부터 유도된 신초를 생장조절 물질을 첨가하지 않은 MS 배지로 옮겨 주었을 때 보다 더 정상적이며 성장이 양호한 뿌리의 분화가 관찰되었다. 재분화 식물체는 순화처리를 위하여 당과 식물생장 조절물질이 첨가되지 않은 MS배지로 계대배양 한 후 인공토양의 화분으로 옮겨 이식하여 관찰한 결과 100%의 생존률을 보였으며 정상적인 재분화 식물체를 대량으로 획득하였다. To establish the optimum conditions of in vitro plant regeneration, the leaf, rhizome, and root explants of Belamcanda chinensis were cultured on the MS medium supplemented with different concentration of 2,4-D and BA. The callus induction was more effective in the root explants than the leaf and rhizome explants, and was the best on MS medium containing 3.0 mg/L 2,4-D or 1.0 mg/L 2,4-D and 3.0 mg/L BA. The highest numbers of shoots were regenerated when callus were cultured on MS medium containing 3.0 mg/L 2,4-D for 4 weeks. However, the multiple shoots were induced on MS medium supplemented with the combination of 2,4-D and BA. The normal root formation from shoot was effective on the MS medium lacking any plant growth regulators. For acclimatization, the regenerated plantlets were cultured on MS medium without sucrose and plant growth regulators for 2 weeks, and then transferred to the pot.

Objectives: This study was conducted as descriptive correlation research in order to survey healthcare personnel(HCP)'s awareness of patient safety culture and their recognition of standard precautions, and to examine the correlation between the two factors. Methods: The subjects were 400 HCPs including 80 doctors, 240 nurses, and 80 medical technicians from two general hospitals. The questionnaire used in the survey consisted of 9 questions on general characteristics, 44 on the perception of patient safety culture, and 21 on the recognition of standard precautions. Results: According to the subjects' general characteristics, the score was significantly higher in those aged over 40 than in those aged 30-39. In addition, it was significantly higher in managers than in practitioners, in those with work experience of less than a year than in those with 5-9 years. The score was also significantly higher in those working 8 hours a day than in those working over 10 hour a day. The number of medical accident reports according to the subjects' general characteristics was significantly larger in nurses than in doctors, in managers than in practitioners, and in those with 10 years' or longer experiences than in those with less than a year. In the awareness of standard precautions according to the subjects' general characteristics, the score was significantly higher in female workers than in male workers, and in managers than in practitioners. As a whole, the subjects' awareness of patient safety culture and their recognition of standard precautions showed a significant correlation with each other. Conclusion: From the result of this study, sufficient work force and the promotion of organizational culture for safety is needed in order to guarantee patient safety. Likewise, these results suggest that experience, job skill, and adequate working hours have a positive effect on the awareness of patient safety culture and the recognition of standard precautions.

권정생 초기 단편동화의 서사 양상 고찰

권혜경(Kwon, Hye-kyung) 한국아동문학학회 2017 한국아동문학연구 Vol.- No.32

권정생은 한평생 병고와 싸우면서도 동화작가로서 치열하게 작품 활동을 했다. 이와 같은 강한 의지력과 치열한 작가 정신 때문인지 당대 다른 동화 작가들에 비해 그의 삶과 문학에 대한 연구가 비교적 많이 이뤄진 편이다. 하지만 양적으로 방대한 연구 결과에 비해 상대적으로 그의 작품에 대한 깊이 있는 연구가 아직까지 제대로 이뤄지지 않고 있다는 비판도 제기되고 있다. 그런 점에 착안하여 권정생의 첫 번째 동화집, 강아지똥(1974)에 수록된 그의 초기 단편동화들에 나타난 문학 형식적 특징 중에서 지금까지의 기존 연구들에서 상대적으로 간과되었던 플롯과 서사 양상에 대해 구체적으로 살펴보고자 하였다. 우선, 권정생은 초기 단편동화들에서 일상에서 흔히 지나치기 쉬운 하찮은 존재들에게까지 미치는 생명 존중의 의식을 나타내기 위해 ‘비극적 플롯’을 선택하였다. ‘비극적 플롯’이야말로 원죄적 존재를 자각하며 자기희생을 통해 ‘죽음’을 극복하는 실천적 사랑의 삶을 지향한다는 점에서 그의 주제의식을 구현할 수 있는 가장 효과적인 서사 방식이기 때문일 것이다. 한편, 권정생은 초기 단편동화들에서 그의 주요 작중 등장인물들을 대체로 ‘고아’로 설정하였다. 이러한 그의 ‘고아 유형’을 세분화시키면 ‘태어나자마자 고아가 된 유형’, ‘한시적 고아 유형’, ‘중간에 고아가 되는 유형’ 등 크게 세 유형으로 나눌 수 있다. 이 중에서 특히 ‘중간에 고아가 되는 유형’과 ‘태어나자마자 고아가 된 유형’이 자주 등장하는데, 이것은 일제강점기와 한국전쟁을 직접 겪은 작가의 개인사와 일맥상통한다는 점에서 당대 시대적 현실을 반영한 결과라 할 수 있다. 또한, 권정생의 초기 동화들에는 주제의식을 확장시키고 깊이 있게 표출하기 위해 ‘상호텍스트성’의 서사 방식이 자주 활용되고 있다. 주로 옛이야기, 전래동요, 성서에 나오는 이야기 등을 액자식 구성으로 보여주었다. 그중에서 특히 성서에 나오는 이야기를 동화속에서 자주 제시한 것은 평생 기독교인으로 살아온 그의 삶과 깊은 관련성이 있다고 할 수 있다. 끝으로 권정생은 다양한 알레고리를 활용하여 비참한 현실과 함께 이상적이며 영원한 삶을 나타낸 작가이다. 그의 초기 동화들에서 ‘별’, ‘하늘’, ‘달나라’를 통해 영원한 삶을 나타낸 반면, ‘시궁창’, ‘눈길’, ‘땅’을 통해 비참한 현실을 형상화하였음을 알 수 있었다. Despite a serious lifelong illness, Kwon Jeong Saeng tried intensely to write fairy stories for children literature before he died in 2007. More studies have been conducted on his life and work than those of other contemporary writers, perhaps as a result of his strong will and intense struggle to be a good writer. However, some critics say that the quality of studies on his works is not adequate. This paper aims to study narrative elements such as plot, intertextuality, and allegory in early short fairy stories from Kwon Jeong Saeng’s first anthology, Puppy Poo(1974), which has not been well researched by previous studies. Kwon Jeong Saeng used the tragic plot to show his respect for the lives of insignificant characters whose existence could be easily ignored. The tragic plot is the most effective narrative mode to realize the theme of practical love to overcome death through the self-sacrifice and the consciousness of original sin. Most of the main characters in Kwon Jeong Saeng’s early short fairy stories are orphans. They fall into three types: born orphans, temporary orphans, and orphans who lost their parents during their lives. Among these types, orphans who lost their parents during their lives appeared most frequently. They represent his tragic life, since he had similar experiences during the period of Japanese colonial rule and the Korean War. In other words, we can say that his early short fairy stories reflect the spirit of the age and his personal experience. Kwon Jeong Saeng also used intertextuality frequently in his early stories, using folk tales, traditional folk songs, and stories from the Bible. His usage of many bible stories in his fairy stories reflects his Christianity. Finally, he used allegory to represent both the tragic reality on earth and the idealistic eternal life in heaven. Eternal life is represented by words like “star,” “sky” and “moon,” while the tragic reality is represented by words like “ditch,” “snowy road,” and “land.”

N/A Objectives : Amniocentesis is the most commonly used invasive method for prenatal diagnosis of genetic disorders. But this invasive study may induce preterm labor, endanger both the mother and the fetus, cause infection and abortion. This study was performed to clarify the safety and confidency of amniocentesis. Material and methods : 1,500 amniocentesis cases were performed from 1987 to 1996 at Severance hospital for prenatal diagnosis of genetic disorders. Of 1,500 cases, 499 cases whose pregnancy outcomes were proven were finally analized. We compared incidence of complications such as spontaneous abortion, vaginal spotting, premature rupture of membranes, preterm labor or chorioamnionitis according to placental location, frequency of needle insertion and amniotic fluid color. Results : 1) Indications for amniocentesis were ① advanced maternal age - 47.3%, ② positive maternal serum triple test - 13.8%, ③ fetal chromosomal anomaly suspected in ultrasonography - 10.0%. 2) 6.6% of the amniocentesis samples had color changes due to bleedng or meconium passing. 3) 18.8% of the cases were performed at 16th gestational weeks followed by 20th, 18th and 17th weeks. 4) 2.2% had complications such as spontaneous abortion, vaginal bleeding, premature rupture of membranes, preterm labor and chorioamnionitis in 4 weeks after amniocentesis. 5) No correlation was found between the placental location, frequency of needle insertion(below 3 times) and complication rate. The spontaneous abortion rate in the group with amniotic fluid discolorization was 6.1% whose only 0.4% had spontaneous abortion to the group with clear amniotic fluid. 6) Median value of amniotic fluid alphafetoprotein(αFP) of pregnant women in midtrimester were 15,769.4ng/ml at 15 weeks, 13,160.3ng/ml at 16 weeks, 11,539.3ng/ml at 17 weeks, 9,569.8 mg/ml at 18 weeks, 8,423.4mg/ml at 19 weeks, 6,527.1ng/ml at 20 weeks, 5,979.3ng/ml at 21 weeks, 4,363.2ng/ml at 22 weeks, 3,555.2ng/ml at 23weeks, respectively. In midtrimester amniotic fluid αFP declined gradually as gestational weeks increase. Conclusions : Fetal loss rate of midtrimester amniocentesis was 0.8%, proving that it outstanding in the aspects of safty and confidency. Since the fetal loss rate significantly increases in case with amniotic fluid discoloration, it is needless to mention the importance of close follow-up.
