Objective : The objectives of this study was to determine the incidence and outcomes of procedural rupture (PR) during coil embolization of unruptured intracranial aneurysm (UIA) and to explore potential risk factors. Methods : This retrospective study evaluated 1038 patients treated with coil embolization between January 2001 and May 2013 in a single tertiary medical institute. PR was defined as evidence of rupture during coil embolization or post procedural imaging. The patient's medical records were reviewed including procedure description, image findings and clinical outcomes. Results : Twelve of 1038 (1.1%) patients showed PR. Points and time of rupture were parent artery rupture during stent delivery (n=2), aneurysm rupture during filling stage (n=9) and unknown (n=1). Two parent artery rupture and one aneurysm neck rupture showed poor clinical outcomes [modified Rankin Scale (mRs) >2] Nine aneurysm dome rupture cases showed favorable outcomes ($mRS{\leq}2$). Location (anterior cerebral artery) of aneurysm was associated with high procedural rupture rate (p<0.05). Conclusion : The clinical course of a patientwith procedural aneurysm rupture during filling stage seemed benign. Parent artery and aneurysm neck rupture seemed relatively urgent, serious and life threatening. Although the permanent morbidity rate was low, clinicians should pay attention to prevent PR, especially when confronting the anterior cerebral artery aneurysm.

The researcher worked with 1001 middle and high school students so as to inquire into family-related variables affecting adolescents' school life maladjustment, relying on average, standard deviation and hierarchical regression. The following are the major findings. 1) The research shows that to look into school life maladjustment on the basis of analysis models including family environment variables and family relationship variables in addition to family background variables offers more explanatory power. 2) Of all the variables, parent relationship variables turned out to have the greatest influences on maladjustment to teacher relationship and teaming activity areas among the subordinate areas of school life maladjustment. 3) Of all the variables, family's physical variables have the greatest influence on maladjustment to regulation-keeping relationship and opposite sex relationship among the subordinate areas of school life maladjustment. 4) Of all the variables, sibling relationship variables have the greatest influence on maladjustment to friendship among the subordinate areas of school life maladjustment. 5) Parent relationship variables have the greatest influence on total school life maladjustment followed by family physical environment, structural environment, the number of family members, cultural environment and residential variables in the right order.

Streptomyces fradiae로부터 Tylosin을 효율적으로 생산하기 위해 지방산 내성균주을 분리 했다. 여러 지방산중에서 oleic acid 1.6 g/l 이상이 첨가될 때 세포 성장이 완전히 저해 되었다. 그러나 oleic arid 1.2 g/l에서 얻어진 TM-224-1 균주는 최대 균체농도와 tylosin 생산이 얻어졌다. 또한 oleic acid 소비속도는 parent strain 비해 3.8배 증가했다. Oleic acid 내성균주, TM-224-1 균주와 parent strain을 이용해서 jar fermentor에서 균체농도, tylosin 생산, 그리고 rapeseed oil 소비를 표준조건하에 5일동안 비교하였다. TM-224-1 균주을 이용할 경우 균체 농도는 초기에 parent strain비해 증가했으나 배양중반부터는 감소하기 시작했다. rapeseed oil 소비의 경우는 거의 비슷했다. 그러나 Tylosin 생산 수율은 parent strain 비해 약 3.2배 증가했다.

본 연구는 학부모의 수학에 대한 인식이 자녀의 수학학습에 영향을 미치는 근원적 요소가 될 수 있다는 선행 연구들을 바탕으로 학부모의 수학 교과에 대한 가치인식과 만족도 등에 관한 내용을 조사하였으며, 그 결과를 바탕으로 학교 수학교육 및 자녀 교육과 학부모 교육에 대한 시사점을 도출하고자 하였다. 본 연구의 연구방법은 전국의 학부모를 대상으로 무작위 추출하였으며, 초등학생 학부모 133명, 중·고등학생 학부모 411명에 따른 학부모의 응답 결과를 비교 분석 하였다. 설문 결과 초등학생과 중·고등학생 모두 학부모가 수학 교과의 가치 인식이 긍정적일수록 자녀의 수학 교과에 대한 가치 인식도 긍정적이고, 학부모의 수학 관련 교육 참여도가 높은 것으로 나타났다. 교수학습 활동에 대한 인식 측면에서 교육 프로그램 참여 의지는 중·고등학생 학부모가 초등학생 학부모보다 낮은 것으로 나타났으며, 수학 교과 전반에 대한 만족도 또한 초등학생 학부모가 더 높은 것으로 나타났다. 또한 학부모들은 미래 신기술을 활용한 수업 및 인공지능이나 데이터 분석 능력을 함양하기 위한 수학교육의 필요성을 인식하고 있는 것으로 판단할 수 있었다. 이는 교육전문가들이 향후 진지하게 고민해보아야 할 과제로서 학부모가 참여하는 수학교육의 확대, 미래 수학학습을 위한 수학 학습 환경의 조성, 수학교육 관련하여 다양한 학부모 교육의 필요성을 제안하였다.

Purpose: This study was done to examine factors influencing cell phone addiction for middle school students by gender. Methods: The participants were 228 male students and 228 female students in two middle schools. Data were collected through self-report questionnaires, and analyzed using the SPSS/WIN 19.0 program. Results: Cell phone addictions of female students are higher than those of male students. Factors influencing cell phone addiction for male students were mimicry, sending text message on weekdays, immediate self-control, grade, syntony, and monthly call charge, explaining 42.2% of variance in cell phone addiction. Factors influencing cell phone addiction for female students were internet addiction, sending and receiving text message on weekends, immediate self-control, long-term self-control, use time, main use, syntony, and monthly call charge, explaining 46.8% of variance in cell phone addiction. Conclusion: The results indicated that cell phone addiction and its influencing factors differed by gender. Therefore the approach to effective cell phone addiction management program for middle school students should consider gender differences.

This study examined variables that affect parent practices and volunteerism, specifically : beliefs of parents about children's education and family-school collaboration, relationships between parent practices and volunteerism, and teacher practices regarding family-school collaboration. Subjects were 651 parents who had children in K-grade 3. Data were analyzed using One-Way Analysis of Variance, Multiple Regression, and Stepwise Regression. Findings were that parents who thought they should be involved actually participated more in their children's education, and parents who reported a greater frequency of receiving information about their children's education and more invitations to volunteer actually were more involved.

Purpose: The Purpose of this study was to investigate the relationships between resourcefulness and the health promoting behavior of high school girls. Methods: The subjects of this study consisted of 117 high school girls on S girls' high school. The data was analyzed with the SPSS computer program that includes descriptive statistics, mean, standard deviation, t-test, ANOVA, Pearson correlation coefficient and multiple regression analysis. Results: The mean age of subjects was 18.0 years old. The mean score of resourcefulness was 114.2. The most frequently practiced resourcefulness item was "By changing my way of thinking, I am often able to change my feelings about almost anything". The next most frequently practiced resourcefulness item was "My self-esteem increases when I am able to overcome a bad habit". There was no difference in the degree of resourcefulness with respect to the general characteristics. The mean score of health promoting behavior was 115.2. The group whose concerns over health was shown high health promoting behavior. The health education class group was shown high health promoting behavior. There was statistically significant positive correlation between resourcefulness and health promoting behavior of high school girls. Conclusion: The findings of this study provides promising evidence to construct further studies on the increasing health promoting behavior programs relating to high school girls. To increase health promoting behavior for high school girls, it is necessary to continue or possibly expand on existing health education programs.

Purpose: The purpose of this study is to compare the mother's rearing attitude and communication between mobile phone addiction group and non-addiction group in middle school students. Methods: A cross-sectional descriptive study was performed with 574 students from 3 middle schools (1 boy school, 1 girl school, 1 coeducation school) at G-city in Gangwon Province. The data was collected from the 10th to 24th of July in 2010. Statistical analysis of the results was carried out by means, frequencies, chi-square, t-test and multiple regression with SPSS/WIN 18.0 program. Results: There were significant differences in mobile phone addiction group and non-addiction group in regard to sex, school year, grades, mother' age, purpose of mobile phone use, activity after school, phone bill per month. Also There were significant differences in mother's rearing attitude and mother's communication between two groups. Conclusion: Mobile phone addiction among students is not serious, however, possibility of becoming an addict still remains. This study suggests that we have to educate them about proper mobile phone use in advance to prevent them from becoming a mobile phone addict in early stage. Therefore, we need to develop an educational program to prevent mobile phone addiction.
