To inspect how the different sensitivities in BAS(or BIS) modulate on the HRV pattern stimulated by positive or negative affective sound, we measured the electrocardiogram(ECG) of 25 students(male : 14), consisted of 4 groups depending on the BAS(or BIS) sensitivity, during listening meditation music or being exposed to noise. The power spectral density(PSD) of HRV was derived from the ECG, and the power of HRV was calculated for 3 major frequency ranges(low frequency[LF], medium frequency[MF], and high frequency[HF]). We found that the index of MF/(LF+HF), during listening music, was higher significantly in the individuals with a low BIS but high BAS than in the individuals with a low sensitivity in both BIS and BAS. Especially in the former group, there was a tendency that the index was higher during listening music than during being exposed to noise. For individuals with a high BIS, regardless of the BAS sensitivity, the difference of this index values was not significant. From these results we suggest that individuals with a low BIS but high BAS are more sensitive to positive affective stimuli than other groups, and the index of MF/(LF+HF) is applicable to evaluate positive and negative affects.

This article considered generally gradational change aspect, character of community for the tombs of the Three kingdoms prepared by some certain homogenous groups. It was completed by tracing the transfering process to grasp character of social structure and organizing System in the community. For this reason, it's analyzed that Wooden chamber tomb was formed in some certain Time-Space of the Yaksadong Buk-dong archaeological site in the Three Kingdom Period. Constructed group was distinguished by the five classes. So perhaps scale of Wooden chamber and sort, material of burial relics, the top layer and the upper layer were established two status those are active the ruling class led the Wooden chamber tomb's society, the general public hold a large majority from the middle class to the lowest class. And it depends on age(nonage-adult) that differed in relation of arrangement, character. It's changed with function or roles, property, purpose etc. of social community in accordance with these individual position, age. Received signification, value of social status were considered with social worth, faith. Members in a community had been conducted under premeditated, organised system for common target, relatedness. Also it seems to attempt organization's own maintenance, persistiveness in norms that given at common law. To do that, relation for combination between members who consisted systems had to be organic. The relation for combination was considered to form relation for the much larger community in based on blood relationship that most vital part. One social structure had established family(house, household) community in based on individual blood relationship, family communities gather up to develop into relative(blood relative, same race) community gradually. Furthermore, relative(blood relative, same race) communities, that focus on the public good gather up to develop into social community in based on regionalism. It's considered to go through the Development Process of family(house, household) community - relative(blood relative, same race) community - social community.

디지털 기술의 발달로 기존의 콘텐츠를 소비하는 역할을 했던 대중들이 손쉽게 콘텐츠를 제작하고 향유할 수 있게 되었다. 이러한 현상으로 최근 디지털 스토리텔링이 큰 화제가 되어 많은 곳에서 공모전 등을 통해 웹 환경에서 콘텐츠를 생산하고 있다. 디지털 스토리텔링은 디지털 기술을 활용하여 만들어진 스토리텔링 콘텐츠로 웹 환경에서 다양한 형태로 제작되고 있다. 하지만 현실은 단순한 저작 도구의 환경이 아날로그에서 디지털로의 변화일 뿐 집단지성을 표방한 웹 2.0 환경에는 동 떨어져 있다. 따라서 본 논문에서는 웹 환경에서 집단지성을 적용하여 협업적으로 제작되는 디지털 스토리텔링 콘텐츠에서 나타나는 절차 및 필요한 요소를 분석하고 이에 맞는 플랫폼을 제안한다.

최근 국민소득수준의 향상을 따라 여름철 전력 수요가 폭증하므로 전력안정 공급을 위한 특별 대책이 필요한 실정이고 환경적인 측면이나 수용가 입장에서 만족스러운 새로운 냉·난방, 전기 공급시스템의 개발·적용이 필요하다. 선진국의 경우, 소규모의 집단에너지 공급이 주류를 이루고 있으며 특히 소규모 열병합 발전시 생산되는 전기, 지역난방열 이외에 냉방에 필요한 냉수를 중앙열원에서 동빌딩을 중심으로하는 구역형 집단에너지 시스템(Community Energy Supply System)등 소규모지역 난냉방 공급방식이 활성화되어 있으므로, 우리나라에서도 냉방/난방/전기부하 패턴 및 하절기 피크부하 경감에 대한 기여도 등을 고려한 경제성있는 최적시스템 구성이 가능한지 검토할 필요가 있다. 소규모 집단에너지사업은 대규모 사업과는 달리 적정 수요예측이 가능하므로 효율적인 초기 투자가 이루어질 수 있으며, 상업용 및 사업용 빌딩 등을 중심으로 부하밀도가 높은 구역을 대상으로 하명서 해당 부하패턴에 적합한 효율적인 시스템의 구성을 통해 수익성이 확보된다면 국가 에너지절약 및 한전의 여름철 전력 피크부하 경감, 대기 환경공해 감소, 도심 도시미관 향상 등의 사업효과가 기대된다. 본문에서는 이러한 소규모 집단에너지시스템 개요 및 국내외 공급 현황, 국내 적용환경, 적용 가능에너지 검토 열원시스템의 기본방향 등에 대하여 언급하고자 한다.

The aims of this study were to identify the significant predictors of the sexual behavior of middle school students. The subjects consisted of 603 middle school students (male 344, female 259). The data was collected through self-report questionnaires, which were constructed to include the attitudes to sexual behavior, sexual permissiveness, perceived behavioral control, sexual behavioral intention, father's child-rearing attitudes, mother's child-rearing attitudes, friends' attitudes to sex, exposure to pornography, and sexual behavior. The data was analyzed using the SPSS 19.0 program. The significant predictors of sexual behavior of middle school students that explained 51.0% of the variance in sexual behavior were the friends' attitudes to sex, alcohol drinking experience, experience of sexual abuse, sexual permissiveness, exposure to pornography, sexual behavioral intention, perceived behavioral control, father's child-rearing attitudes, and mother's child-rearing attitudes. These findings suggest that the approach to a sexual education promotion program for middle school students should consider multisystemic predictors.

본 연구는 중학교 1학년 함수 학습을 위해 패턴 활동으로 구성된 함수 지도 프로그램을 개발하고, 개발한 프로그램을 적용한 실험 집단(85명)과 교과서를 적용한 비교 집단(85명)간의 함수 학습에서의 효과를 분석하였다. 함수 지도 프로그램은 학생들이 패턴 활동을 동해 함수적 사고를 기르며, 활동적으로 수업에 참여하여 수학에 대한 자신감과 실생활의 연계성을 가질 수 있도록 구성하였으며, 적용 결과, 수학 수준별 수업을 하는 상반에서는 유의미한 차이를 보였고, 중반에서는 유의미한 차이는 없었으나 수업 시간에 흥미가 매우 높았다는 긍정적 평가를 할 수 있다.

The genetic variabilities of second chromosomes of Drosophila melanogaster concealed in Busan natural and experimental populations have been analyzed by the Cy//Pm method. The experimental population was composed of D. melanogaster which had the lethal-free second chromosome, collected Sasang natural population in 1982. The frequencies of deleterious genes were estimated to be 14.3∼25.4% in Busan natural population and 26.5∼27.2% in experimental population. The allelism rates in lethal genes isolated from the natural and experimental populations were calculated to be about 0.76% and 9.76∼14.17%, respectively. The value of elimination by the frequencies of deleterious genes and allelism rate was 0.0106and the effective population size estimated to be about 430 flies at the 6570 days population.

The late 18C Malthus studied population growth for the first time, Verhulst the logistic model in 19C and, after that, the study of the predation competition between two species resulted in the appearance of Lotka-Volterra model and modified model supported by Gause's experiment with bacteria. Instable coexistence equilibrium being found, Solomon and Holling proposed functional and numerical response considering limited abilities of predator on prey, which applied to Lotka Volterra model. Nicholson and Baily, considering the predation between host and parasitoid in discrete time, made a model. In 20C there were developed various models of disease dynamics with the help of mathematics and real data and named SIS, SIR or SEIR on the basis of dynamical phenomena.
