In this paper, we implement a digital content that visualizes 33 Avalokitesvara-Bodhisattva according to the wishes of the public. The 33 Avalokitesvara-Bodhisattva is described in the Avalokitesvara-Bodhisattva tale that is found in the ancient literature "Memorabilia of the Three Kingdoms" as Tangible Cultural Heritage. Also, it is easily found in a wall painting of traditional Buddhist temples. The 33 Avalokitesvara-Bodhisattva is the saint of mercy that transforms into 33 various forms according to the wishes of the public. The Avalokitesvara-Bodhisattva tales deal with differences in the types of wishes of the public, and the tales have been speeded like wildfire among the people. So, in this paper, we classify them into 4 groups by the wishes (healing, security, academic achievement, disaster relief) of the public, and then analyze its symbolism and activity of the 33 Avalokitesvara-Bodhisattva. Also, we implement a 2D digital content that represents visually it according to the wishes of the public. Applications of the implemented visual content are as follows; development of character, game, and digital storytelling associated with traditional culture, education service for Buddhist doctrines, etc.

In recent years, the VR-interactive action contents industry, which utilizes five senses of human bodies, has continued to grow through areas such as games, tourism, movies, performances and exhibitions, but it has reached to breaking point by unrealistic visual elements. Therefore, the purpose of this study is to analyze the effect of each evaluation factor based on visual immersion of interactive type of VR action contents to overcome the limitations. For this study, firstly, prior research is reviewed. Secondly, the evaluation factors of visual immersion of interactive type of VR action contents and hypothesis are to be derived. Research finding is that there is no difference to recognize proximity, three-dimensionality, visibility and immersion by gender. Also, in order to influence visual immersion, it is important that 3D modeling of characters and objects must be sophisticated to be fit in with their surroundings and lighting. This makes user to be confused where they are actually in.

Creating controllable, responsive avatars is an important problem in computer games and virtual environments. Recently, large collections of motion capture data have been exploited for increased realism in avatar animation and control. Large motion sets have the advantage of accommodating a broad variety of natural human motion. However, when a motion set is large, the time required to identify an appropriate sequence of motions is the bottleneck for achieving interactive avatar control. In this paper, we present a novel method for training avatar behaviors from unlabelled motion data in order to animate and control avatars at minimal runtime cost. Based on machine learning technique, called Q-teaming, our training method allows the avatar to learn how to act in any given situation through trial-and-error interactions with a dynamic environment. We demonstrate the effectiveness of our approach through examples that include avatars interacting with each other and with the user.

수자원과 관련된 많은 분쟁 및 갈등들은 국내뿐만 아니라 전 세계적으로 발생하고 있다. 따라서 분쟁 및 갈등해결을 위한 많은 연구들이 진행되고 있지만 수자원과 관련된 분쟁들은 대부분 원활한 해결을 이루지 못하고 있으며, 특히 국내의 경우에는 더욱 심각하다 할 수 있다. 따라서 제한된 자원인 수자원을 둘러싸고 수자원분쟁이 일어나는 것은 당연한 일이라 할 수 있으며, 분쟁의 양상도 다양하다. 댐 건설로 인한 상류지역과 하류지역의 갈등, 수로의 건설로 인해 수자원을 빼앗기는 지역과 수자원을 얻게 되는 지역 간의 갈등, 새로운 공단이나 개발로 인하여 하류지역에서 수질악화를 우려하여 반대하는 경우 등 여러 종류의 수자원으로 인한 분쟁이 있다. 수자원을 둘러싼 갈등이 쉽게 해결이 되지 않고, 또한 갈등 및 분쟁이 쉽게 발생되는 이유도 주체자들간 입장 차이에서 오는 성격이라 할 수 있겠다. 수자원과 관련된 분쟁에서 오는 여러 가지 갈등들은 사회적으로 많은 문제들을 발생시켜 수자원의 원활한 공급이 저해될 수 있다. 이로 인해 사회적으로 수자원과 관련된 분쟁 해결에 들어가는 많은 시간과 노력, 비용을 생각해 볼 때, 효과적인 갈등 및 분쟁의 해결은 국가적 발전에 있어서 영향을 줄 수 있다. 그러므로 갈등 및 분쟁의 원활한 해결이 국가적 발전에 많은 비중을 차지 한다고 할 수 있다는 것은 이런 이유들 때문이라 할 수 있다. 본 연구에서는 국내 수자원과 관련된 분쟁사례들을 하천의 기능에 따른 분류, 발생 원인에 따른 분류, 분쟁주체에 따른 분류 등을 유형별로 구분하여 수자원분쟁의 여러 가지 사례들을 조사하였다. 또한 분쟁 및 갈등을 해결하기 위한 방안으로 거버넌스 시스템을 적용하였고 분쟁의 원활한 합의 조정방안 및 문제점을 제시하기 위한 외국의 시민참여 모델을 특징 및 특성을 분석하였다. 또한, 공영시각모형, 게임이론, 제도설계이론의 공학적 모형을 바탕으로 물분쟁의 해결을 위한 대안을 모색할 수 있는 과학적 접근 방안을 제시하여 향후 여러 가지형태의 국책사업 시행 시 발생 할 수 있는 분쟁의 해결 및 조정을 위한 방안으로 활용할 수 있는 토대를 마련하고자 한다.

The purpose of this study was to develop a multimedia game program as a strategy for teaching alien species and to examine the effect of the program on recognition, motivation and achievement about alien species. In order to find the effect of developed program, 62 students among 6th graders at S Elementary School located in Gyeonggi-do were divided into two groups. Lesson with multimedia game was given to the experimental group, and the control group received traditional lesson. The results were as follows. First, the experimental and control groups showed significant difference in recognition of alien species. Second, the two groups showed statistically significant difference in learning motivation. For the subdomains of the recognition, significant results were obtained at the significance in attentiveness, relevance, confidence and satisfaction. Third, the two groups showed significant difference in academic achievement. Lastly as a result of interviewing subjects of the experimental group about lesson based on game, subjects generally had positive opinions that the new learning method is interesting and has helpful influence on the lesson.

A 3D laser scanner is widely used in various fields such as games, movies, medicines, art, design, etc. Many studies for utilizing the 3D laser scanner in the fields of civil engineering have also been carried out, for example, for systematically managing tunnel and/or bridge construction. However, since a software which is directly applicable to Korean construction system does not exist, the amount of data obtained from existing the 3D laser scanner is too much to handle in a systematic way. Therefore, in this paper, a new data processing technique was established which can rapidly and effectively treat the 3D laser scanning data. Moreover, a software that can systematically manage the tunnel construction was developed. The developed software can assess the construction quality of tunnel excavation such as under-break, over-break, cracks, leakage and efflorescence, etc. A 3D laser scanner and the developed software was applied to an in-situ tunnelling site, and verified usefulness of the 3D laser scanner. The developed software may be useful for tunnel maintenance as well as for systematic management of tunnel construction.
