The purpose of this study is to analyze the relationship between the self-leadership and the cognitive flexibility of the university students who are majoring in dance to provide useful information in the field of dance instruction. Participants were the students majoring in dance who are enrolled in the dance department of the four-year universities nationwide and 282 data have been used for the final analysis. The analytical method for verification of hypothesis was multiple regression analysis to be performed at a significance level of ${\alpha}$=.05. As the result, the following conclusions have been gained. First, the constructive thinking pattern among the sub-factors of self-leadership had a positive influence on the flexibility of preferred varieties which is a sub-factor of cognitive flexibility. However, the behavior-oriented and natural reward self-leadership did not have influence on the diversity preferred flexibility. Second, the natural reward and constructive thinking pattern among the sub-factors of self-leadership have positive influence on the flexibility of preferred complexity which is a sub-factor of cognitive flexibility while the constructive thinking pattern flexibility was shown as exercising a very powerful influence. But the behavior-oriented self-leadership did not have influence on the flexibility of preferred complexity.

There are varieties of severe malocclusions, which can be treated orthodontically, but with a great deal of effort. Anterior openbite, in particular, is one malocclusion thought to be more difficult to treat, and therefore, most of them have to be corrected by means of surgical intervention. To solve these problems, numerous studies pertinent to treatment modalities have been introduced with controversies on the effectiveness of treatment. Suggested treatment modalities for anterior openbite are based directly or indirectly on the neuromuscular and morphological features and on the etiologic and/or the environmental factors. Even though the vertical relationship of the face is increased due to the growth variation, the normal occlusal relationship can be achieved by the adequate dentoalveolar compensatory mechanism, but in the case of inadequate or negative dentoalveolar compensation, openbite is likely to be present. If the skeletal dysplasia is too severe to be solved by orthodontic treatment alone, combined treatment with surgery should be done to restore the function and the esthetics of the orofacial complex. In many cases, however, orthodontic alteration of the dentition pertinent to the given skeletal pattern with the proper diagnosis and treatment planning can bring satisfactory results. The treatment changes with the Multiloop Edgewise Archwire(MEAW) therapy occurred mainly in the dentoalveolar region and showed a considerable similarity to the natural dentoalveolar compensatory mechanism. In other words, the MEAW technique allows orthodontists to produce the natural dentoalveolar compensation orthodontically. Even if an openbite is corrected by the orthodontic dentoalveolar compensation suitable for the skeletal pattern, relapse may still occur by the persisting etiologic factors which originally prohibited the natural dentoalveolar compensation. The etiologic factors should be determined at the time of initial diagnosis and should be controlled during treatment and retention.

The purpose of this study is to investigate the relationship between self leadership and empowerment and organization innovation action in private security guard. This study established private security guards who is being located in Seoul, 2011 and work in the private security company by population. Using purposive sampling method, 293 samples were drawn and were used for the final analysis. Using SPSSWIN 18.0, frequency analysis, factor analysis, reliability analysis, multiple regression analysis and path analysis were performed. Cronbach's ${\alpha}$ value which shows the reliability of the questionnaire came out to be over .831. The conclusion is following. First, private security guard's self leadership affects to empowerment. That is, influence and semanticity are enlarged as action center strategy, natural compensation strategy is attained well. Also, capacity, self decision power is enlarged as constructive thinking strategy, natural compensation strategy is attained well. Second, private security guard's self leadership affects to organization innovation action. In other words, innovation action is increased as action center strategy is attained well. Also, organization's innovation result is enlarged as constructive thinking strategy, action center strategy, natural compensation strategy are attained well. Third, private security guard's empowerment affects on organization innovation action. That is, innovation action, innovation result appears high in case of influence, semanticity is enlarged. Fourth, private security guard's self leadership exerts direction indirect effect in empowerment and organization innovation action. Thus, empowerment is an important variable that mediate self leadership and organization innovation action.

This study aims to investigate the hierarchical stepwise migration and its influences on regions (metropolitan areas, cities and counties of Korea administrative district) through analyzing the city rank-size and the changes of natural increase of population. The result shows that the inter-regional migration has been associated to the decrease of the population and the decline of NIR in the regions where outflows have been persisted. Also, theses demographic events have sequentially occurred through the hierarchy of settlement system: gradually from rural (gun) and lower ranked regions in the system of city rank-size, to urban (si) and regions in the high ranks in the system. Based on the result of this study, it is possible to understand and expect the major origins of inter-regional migration, the presence of the hierarchical stepwise migration and most significantly, the spatial expansion of depopulation problems.

A total of 48 dust samples were collected from large shopping mall parking lots in Daegu metropolitan city in March 2011. Samples were sieved through a 100 ${\mu}m$ mesh and the concentration of 14 elements have been determined using by ICP after acid extraction. Results showed that Ca, Fe, K, Mg, Mn, Na and V were affected by natural sources while Cd, Cr, Cu, Ni, Pb and Zn were affected by anthropogenic sources. The measured values were remarkably higher in components from natural sources than in components from anthropogenic sources. Anthropogenic trace element concentrations of ground roof dust were higher than those of ground and underground indoor dust. A large percentage of trace elements came from natural sources rather than anthropogenic sources. The percentage composition of chemicals of ground roof dust were higher than those of ground and underground indoor dust. This study showed that investigated parking lots were rarely contaminated with hazardous heavy metals. The heavy metal pollution of ground roof were higher than those of ground and underground indoors. The correlation analysis among trace elements suggest that components in ground roof were more highly correlated than those in ground and underground indoor. Also anthropogenic trace element levels were well correlated with parking lot age and parking density.

유전자 알고리즘(Genetic Algorithm, GA)은 자연적 진화과정에서 생존 경쟁 측면의 가장 적합한 메커니즘이다. GA를 소프트웨어로 수행하는데 큰 지연시간은 필수적이기 때문에 하드웨어 설계를 이용하여 알고리즘 실행 속도를 증가시키기 위한 많은 연구가 진행되어 왔다. 본 논문에서는 염색체의 임의의 유전인자를 기준으로 입력 받은 염색체에 대하여 GA 연산을 수행하는 유전 연산자를 설계한다. 설계된 디자인을 ARM 코어와 PLD로 구성된 Altera사의 Excalibur칩에 구현하여 동작을 검증하였다.

실세계에서의 바람은 크게 자연 현상으로서의 바람과, 사람의 입, 선풍기, 에어컨, 환풍기 등에서 생성되는 인위적인 바람으로 나눌 수 있다. 본 논문에서는 인위적으로 생성되는 바람을 컴퓨터 그래픽스 분야에서 사용하기 위한 모델을 제안한다. 또, 가상환경에서 이 모델을 이용하여 생성된 바람이 물체와 부딪쳐서 만들어내는 힘을 효과적으로 반영하는 방법을 제시한다. 새로 제안한 방법은 가상 현실 환경과 같이, 실시간 처리를 필요로 하는 분야들에서도 적용 가능하도록 설계되었으며, 자연적인 바람에 대한 기존 연구 결과들과 통합되면 종합적인 가상 바람 생성 시스템으로 사용될 수 있을 것으로 기대된다.

대기를 통해 물질과 에너지가 순환한다는 것은 이미 잘 알려진 지구화학적 과정이다. 즉, 대기를 통해 자연적 혹은 인위적인 원인으로부터 배출되는 여러 가지 물질들이 인근지역이나 때로는 광범위한 지역으로 이동되고, 태양으로부터 오는 빛을 가스나 입자상 물질들이 흡수, 산란시키거나, 일부 미세한 입자상 물질들은 구름의 응결핵으로 작용함으로써 지구의 에너지 균형에도 관여한다. 에너지나 물질의 순환이라는 측면에 더하여 가스나 입자상 물질들은 대기 중에 머무는 동안 인체나 주변 생태계에도 영향을 미치게 된다. (중략)

최근 환경오염에 대한 인식과 규제가 증가하고 쾌적한 주변환경에 대한 관심이 높아짐에 따라 대기, 물, 토양, 생물 등과 같은 여러가지 환경시료의 분석을 통하여 오염의 정도를 파악하고 오염원을 규명하여 환경관리정책에 반영하려는 노력이 추진되고 있다. 여러 가지 환경시료중 대기분진은 자연적 또는 인위적 발생원에 따라 다양한 원소들을 함유하고 있기 때문에 대기환경지표시료로 이용되고 있다. 오염원의 규명을 위한 소량의 휠터상 분진시료로부터 원소의 정확한 분석은 필수적이고 중요한 선행작업이며 적합한 측정분석법의 이용이 요구된다. (중략)
