이 글은 한국에서 뇌신 신앙과 술법이 전개된 역사적 양상과 특징에 대한 종교사적 연구로서, 역동적 종교문화의 이해를 위해 뇌신 신화를 통해 정치 권력을 초월적으로 정당화하거나 백성의 민생을 의례적으로 주관하는 국가권력 혹은 관방도교의 종교적 관심, 무교나 도교와 연관된 민간신앙 혹은 민족종교의 가능성 및 가뭄, 전쟁, 질병 등의 위기 혹은 문제상황에서 뇌신이 호출되고 신앙되는 다양한 종교적 관심의 유형을 파악하여 설명했다. 고조선을 비롯한 고대 국가의 신화에서 뇌신은 삼계를 다스리는 하늘의 지고한 주재자로 등장하고 지신 혹은 수신과 결합하는 신성혼을 통해 지상의 권력을 정당화했으며, 뇌신과 연관된 태일은 주변화되어 민간 도교 속에서 원시부려천존, 구천응원뇌성보화천존, 옥황상제 등의 종교적 상상력의 근간이 되었다. 고려부터 조선 중기까지는 도교적 재초와 농경사회의 기우제를 해결하는 의례적 차원에서 뇌성보화천존이 국가적으로 주목받았으나, 조선 전기에는 선사시대의 돌도끼가 뇌신의 벼락 도끼인 뇌부로 인식되면서 다양한 병 치료에 효험이 있다는 신앙이 전개되었다. 조선 후기에는 뇌신이 전쟁 극복과 치병을 위한 존재로 부각되었는데, 전쟁 극복을 위한 다양한 도교 술법이 수용되기도 했고, 칠성검이나 사인검 등의 도검이 애호되었으며, 민간에서는 『옥추경』을 활용한 앉은 굿을 통해 면면히 영향력을 유지했다. 대순진리회를 비롯한 근대 민족종교에서는 후천개벽과 해원상생의 관점에서 뇌신의 위상이 초월적 주재자로서 조명되는 민간종교 혹은 민족 종교로서 새롭게 재전유하는 양상이 나타났다.

The aim of this study is to explain characteristics of Maitreya and Maitreya belief from a point of view that 'Jeungsan is the very Maitreya(甑山卽彌勒)'. In 『Jeon-gyeong』, Maitreya is mentioned several times. Thus, new religions of Jeungsan of Daesoonjinrihoe take 'Jeungsan is the very Maitreya' belief for truth. Due to the fact that characteristics of Maitreya are so multi-layered and complicated, it is necessary to explain clearly what kind of feature Maitreya has in 『Jeon-gyeong』. If believing and following 'Jeungsan is the very Maitreya' without clarifying it, they will be faced with a problem that they regard Jeungsan of Supreme being of the Ninth Heaven as one of Maitreya and take its belief for truth. Furthermore, with respect to the characteristics of 'Jeungsan is the very Maitreya' belief, while believing in Mireukasaeng, longed-for Millenarian movement by people through Messianism and Mireukasaeng belief is found in Daesoon Thought, whereas there is a need how to understand the point that we cannot finped Messianism and Millenarian movement in Daesoon Thought. To solve this problem, I draw a conclusion that 'Jeungsan is the very Maitreya' in 『Jeon-gyeong』 has to be understood with two meanings by four demonstrations. First of all, the people perceived late Joseon dynasty as the age of decadence but Maitreya's divinity which is desired by the people is not divinity of Maitreya Sutra(Mileuggyeong). Maitreya's divinity is reflected in the people's cherished desire and it is newly created as the Messiah. Thus, the idea of Jeungsan being the very Maitreya was developed in a way that the people desired the Messiah, encompassing this inclination. That is the Messiah of the people and the divinity of Jeungsan. Although Jeungsan as Supreme being of the Ninth Heaven satisfied the people's desire, it shows a different way to salvation from the way in Maitreya Sutra(Mileuggyeong). It is 'the Great Reordering of the Universe' and 'the Great Reordering of the Three Realms'. Reordering in Jeungsan shows that divinity of Jeungsan is not limited to the people's Messiah. In other words, divinity of Jeungsan is established as The Messiah, surpassing divinity of Maitreya Sutra(Mileuggyeong). And following statements prove this divinity of Jeungsan. Jeungsan's emphasis is not only the people's desire and the Gods' appeal. Jeungsan's emphasis is that only does Supreme being of the Ninth Heaven correct heaven and earth, which is the Gods' appeal. Therefore, 'Jeungsan is the very Maitreya' belief embraces the people's Messianism and at the same time it runs with he Gods' appeal. Thus, Reordering through the Great Reordering of the Universe and the Great Reordering of the Three Realms builds up a new ideal world.

In this study, we have evaluated the effect of amplitude and frequency perturbation of EGG signal during single vowels associated with laryngeal pathology. The normal EGG signal is properly characterized by an autoregressive model which has the optimal order of ninth using the parametric method. This can be analyzed by determining the transfer function. Perturbations in the fundamental pitch and in the peak amplitude of EGG signal derived with a four-electrode system using the modulation/demodulation techniques were investigated for the purpose of developing a decision criteria for the laryngeal function identification.

일상적인 경험을 바탕으로 중학생들이 도구를 사용하지 않고 물리량의 치수를 어림하는 능력을 조사하였다. 이를 위하여 연구자들은 기본량에 해당하는 길이와 질량, 유도량에 해당하는 속력, 부피, 밀도에 대한 차수 어림 능력을 묻는 선택형 문항을 개발하였고, 서울지역 중학교 1학년과 3학년 학생 448명이 조사에 참가하였다. 전체적으로 반 이상의 학생들이 물리량의 치수를 참값과 다르게 어림하고 있었는데, 차원이 복잡한 유도량이거나 크기가 작을수록 차수 어림 능력이 낮아졌다. 학년에 따른 차이는 크지 않았으나 성별에 따라서 차수 어림 능력에 차이가 있었고 상대적으로 남학생이 길이 어림을 잘 하였다. 결론적으로 반수 이상의 학생들이 물리량이 차수를 제대로 어림하지 못한다는 점은 물리량과 단위에 대한 정성적인 이해가 부족함을 나타내며, 기능적인 측면을 강조하는 측정 교육이 가지는 한계점을 보여주었다. 따라서 실제 측정을 통하여 구한 물리량의 정성적인 의미를 이해할 수 있도록 하기 위하여 어림 교육이 필요함을 시사하고 있다.

The overall purpose of this study was to investigate the effects of level of isoflavones supplementation on bone metabolism in growing female rats. The effects of level of isoflavones supplementation on bone mineral density (BMD) and bone mineral content (BMC) were inspected in this study. Forty-five rats divided into three groups: Casein, $^1/{_2}IF$, IF. The serum and urine concentrations of calcium and phosphorus were determined. BMD and BMC were estimated by using PIXImus (GE Lunar Co, Wisconsin.) in spine and femur on 3, 6, 9 weeks after feeding. This study of results were as follows: The isoflavones supplementation level did not affect weight gain, mean food intake and food efficiency ratio. The serum concentration of calcium, phosphorus were not significantly different by different level of isoflavones supplementation. The urinary calcium and phosphorus excretion were not significantly different, too. Spine and femur BMD, BMC were not significantly increased by different level of isoflavones supplementation on 3 and 6 weeks after feeding. Spine BMD and spine BMC per weight, femur BMC per weight were significantly increased in the groups $^1/{_2}IF$ and IF at the ninth week after feeding, but there was no significant difference by different level of isoflavones supplementation. Spine BMD per weight and femur BMD per weight were significantly higher in the group of IF than in the group of Casein and $^1/{_2}IF$ at the ninth week after feeding. These results suggest that the group of IF with rich isoflavones supplementation was effective to the increase of BMD spine and femur in growing female rats, respectively.

What an individual values and regards as important has a significant impact on his or her learning. Classroom instruction would be even more effective if what the teacher regards as important in his or her pedagogical practice are aligned with what students regard as important too. Given this background, this study sought to find out what Korean students valued about mathematics and mathematics learning using a questionnaire developed by Seah (2005). The participants were 409 students from Grade 6 and 407 students from Grade 9 in Korea. The results of this study showed that students put the biggest emphasis on ideological aspects of mathematics, specifically rationalism, among mathematical values. The students also valued product, computation, process, exposition, and recalling among values related to the learning of mathematics. A comparative analysis between the two groups of students showed that sixth graders tended to think more positively with regards to each value than ninth graders. On the basis of these results, this paper raises some issues about students' values in mathematics learning. It also suggests that teachers need to consider what students value and regard as important in their mathematics learning to bring about even more effective instruction.

Background The aim of this investigation was to systematically review the current literature to provide the best data for indications, outcomes, survival, and complication rates of pedicled propeller perforator flaps for upper body defects. Methods A comprehensive literature review for articles published from January 1991 to December 2011 was performed using the PubMed, Medline, and Cochrane Databases. Articles without available full-text, single case reports or papers with excessive missing data were excluded. Papers reporting pedicle-perforator (propeller) flaps used for lower extremity reconstruction were excluded from meta-analysis. Results From the initial 1,736 studies our search yielded, 343 studies qualified for the second stage of selection. Of 117 full-text reports screened, 41 studies, met the definitive inclusion and exclusion criteria. Of the selected 41 articles, 26 were case series, original papers or retrospective reviews and were included, whereas 15 were case report papers and therefore were excluded. Two hundred ninety-five propeller flaps were reported to have been used in a total of 283 patients. Indications include repair of trauma-induced injuries, post-trauma revision surgery, cancer resection, chronic infection, pressure sores, and chronic ulcers with a major complication rate (3.3%) comparable to that of free flaps. No specific exclusion criteria for the procedure were presented in the studies reviewed. Conclusions Pedicled propeller flaps are a versatile and safe reconstructive option that are easy and quick to raise and that provide unlimited clinical solutions because of the theoretical possibility of harvesting them based on any perforator chosen among those classified in the body.

Objectives: The purpose of the study is to investigate the relationship between dental caries and oral health behaviors in middle and high school students by web-based survey of the ninth(2013) Korean youth risk behavior. Methods: The subjects were 75,149 students from 400 middle schools and 400 high schools. Finally, the survey participation rate was 96.4%(72,435 students from 799 schools) by complex sample design. The questionnaire consisted of general characteristics of the subjects, oral health behaviors, and oral health status. General characteristics included gender, types of schools, economic condition, and residential types. Oral health behaviors included subjective oral health condition, frequency of tooth brushing, tooth brushing after meal within recent 7 days, sealant within 12 months, fluoride application within 12 months, scaling within 12 months, and oral health education experience within 12 months. Oral health condition included dental caries incidence within 12 months. Results: Oral health behavior influenced on dental caries in the middle and high school students in Korea. This study showed the relationship between the sociodemographic characteristics, tooth brushing frequency, sealant experience, dental caries and halitosis experience, and scaling within 12 months. Scaling is the best prevention method for dental caries and halitosis in the students. Conclusions: The study showed the necessity for practical oral health education and the effect of fluoride application for dental caries prevention.
