This study investigates how 'multi-perspective' can be utilized in animation. For this goal, 1 used the traditional techniques of Korean folk paintings called 'Minhwa.' Most 'Minhwa' works, employ 'multi-perspectives', instead of linear perspective of the Western tradition that has been only taught to students under the formal education system. In Minhwa parts of reality are not only stylized but also fragmented and combined within the same frame. Other common techniques of 'Minhwa' include frontal view, bird's eye view, and inverse-perspective, which are of ien combined in one single work. The purpose of this study is to develop a working principle and practically apply it to , an animation piece based on the Korean folktale of the same title. In doing so, I have proposed a way to reconstruct and revitalize the traditional art form in the age of digital technology and have concluded that 'Multi-perspective' in 'Minhwa' can be utilized in other contents such as animation.'Multi-perspective' in 'Minhwa' is a rich source that has numerous cultural applications.

In a digital environment that is keep in change content from smart phones to tablet PC are a social network service is holding deep place in our lives. Social networking applications has building a network and communication with others than other application, it means that Social networking applications are sharing not only personal purpose in that trend of variety and competition of these social networks can be expected to trend and be developed thru analysis of user certification. this study of social network service application is proposed to developing of application thru analyze the two-effective application which is high ranked in google store. the theoretical foundation was set based on the seven elements of the social network service of the information structures designed by Jean Smith. This study proceeded analysis is for the functional elements of Facebook and Instagram, and the advantages and disadvantages through survey research. As a result of the empirical analysis to user of Instagram and face book of communication, identity, satisfaction for the group are equally. Instagram is about the presence, reputation, and Facebook has had a high level of satisfaction for each sharing and relationship. Facebook got high satisfaction from sharing features, but user feel of discomfort in the randomly showing advertising content. Instagram is not showing off advertise on common page of content, it is good point to be complementary to facebook. And, Instagram hashtag is good for convenience, but satisfaction is high with Facebook. in order to increase the satisfaction of Instagram, it is necessary to consider the main advantage of the communication and the functional aspects of the share from facebook.

Dowel bars in the jointed concrete pavement are used to both provide load transfer across pavements joints and prevent the joint faulting leading to longer service life. On the contrary, the misplacement of dowel bar can provide negative results including the joint freezing(locking) that may cause the joint spatting and unexpected mid-slab cracking. The dowel bar can be placed using the assembly or dowel bar inserter (DBI) during the concrete pavement construction. In the domestic practice of the concrete pavement construction, the dowel bar is placed using the assembly method. This study primarily focuses on the comparison of these two dowel placement methods using the field data from the KHC test road in which both dowel placement methods have been applied to a certain length of the concrete pavement. The field data regarding the alignment of the dowel bars placed by both methods was collected using MIT-SCAN2, a nondestructive measuring equipment, and processed to compute Joint Score and Running Ave. Joint Score which are used as indicators of the dowel bar performance. The comparison of the methods for the dowel bar placement using these indicators shows that the DBI method provided much better alignment of the dowel bars reducing the risk of joint freezing than the assembly method. In order to improve the quality of the dowel bar placement using the assembly method, the current weak points of the assembly method including the fabrication, storage, and installation of dowel bar assembly were investigated and the solution was suggested. The improved dowel bar sets based on the suggested solution have been applied to an actual practice of the concrete pavement construction. The field data shows that the improved assembly method suggested in this study can highly reduce the risk of joint freezing.

The 4 bank mico-MLC (mMLC; Acculeaf, Direx, Isral) has been commissioned for clinical use of linac based stereotactic radiosurgery. The geometrical parameters to control the leaves were determined and comparisons between measured and calculated by the calculation model were performed in terms of absolute dose (cGy/100 MU). As a result of evaluating calculated dose for various field sizes and depths of 5 and 10 cm in water in the geometric condition of fixed SSD (source to surface distance) and fixed SCD (source to chamber distance), most of differences were within 1% for 6 MV and 15 MV x-rays. The penumbral widths at the isocenter were approximately evaluated to 0.29~0.43 cm depending on the field size for 6 MV and 0.36~0.51 cm for 15 MV x-rays. The average transmission and leakage for 6 MV and 15 MV x-rays were 6.6% and 7.4% respectively in single level of leaves fully closed. In case of dual level of leaves fully closed the measured transmission is approximately 0.5% for both 6 MV and 15 MV x-rays. Through the commissiong procedure we could verify the dose characteristics of mMLC and approximately evaluate the error ranges for treatment planning system.

Rockbursts are mainly caused by a sudden release or the stored strain energy in the rock mass. They have been the major hazard in deep hard rock mines but rarely occur in tunnels. Due to the short history and limited information on rockbursts, the topic has rarely been studied in Korea. Some cases of rockbursts, however, have been reported during construction of a mountain tunnel for waterway. This study focuses on analyzing data on rockbursts obtained from a TBM (Tunnel Boring Machine) tunnel and suggests methods for a comprehensive understanding on rockbursts. From the analysis of the field data of rockbursts, it was found that most rockbursts mainly occurred at the section between the tunnel face and the TBM operating room, and the rock bursting phenomena lasted up to 20 days after excavation in certain areas. The data also show that the bursting spots are located all around the tunnel surface including the face, the wall, and the roof, The maximum size of bursting spots is usually less than 100cm. This study also suggests new scale systems of brittleness and uniaxial compressive strength to evaluate the possible tendency for a rockburst. These systems are scaled based on the scale system of strain energy density. In addition, with these scale systems, this research shows that there are potentially higher tendencies for rockbursts in this specific tunnel. Moreover this research suggests that properties of rock and rock mass, RMR (Rock Mass Rating) value, tunneling method, excavating speed, and depth of tunnel have a strong correlation with rockbursts.

Thanks to mass production and provision of smartphones and the HMD (head mounted display), VR (virtual reality) is now being applied to various areas. The VR HMD is the interface equipment which allows users to have realistic experiences through human sensory organs such as vision and auditory sense. Since the majority of VR equipment is operated by the display for both eyes, 360-degree video content and the depth information, the VR mechanism is closely related to human senses, especially vision. Previous studies have focused on how to minimize negative impact such as motion sickness or visual fatigue. Little attention has been paid on research about the visual treatment. Therefore, the focus of this study is to develop technical elements for utilization of vision therapy with the VR HMD and explore possible areas to apply it. To this end, we analyzed the past case studies and technical elements to identify 16 areas for vision therapy. We also developed the optical parameters for utilization of the VR HMD visual targets. The result of this study is expected to be utilized for development of visual targets for vision therapy based on the VR HMD.

액체/고체 경계면에 레일레이각으로 초음파 pulse를 입사시키면 입사된 에너지의 상당 부분이 고체쪽으로 침투여 표면으로부터 약 1.5 파장 깊이 정도까지 에너지 분포를 가지고 고체 표면을 따라 전파하는 레일레 이파로 전환되며, 이러한 입사각에서는 기하학적인 거울 반사가 일어나지 않고 반사파의 중심이 Schoch 변위만큼 전방으로 이동되고, 또 입사 방향으로 후반 산란되는 초음파의 신호가 급격히 증가하는 현상이 관찰된다. 만일 고체에서 초음파의 감쇠가 산란에 의해 크게 영향을 받고, 레일레이각에서 고체 쪽으로 침투한 에너지의크기를 $E_0$라고 하면, 고체 표면과 표면 근처를 전파하는 레일레이파의 산란파 에너지, $E_S$는 Schoch 변위, ${\Delta}_S$와 산란에 의한 감쇠계수 ${\alpha}_S$에 비례하는 관계가 있음을 이론적으로 구하였다. 입사 방향으로 후방산란되는 초음파는 산란파의 일부이므로 후방산란 초음파 에너지, E_{Bs}도 이와 같은 관계를 가진다. 그러므로, 레일레이각으로 입사된 초음파의 후방산란 에너지, $E_{B_S}$ 산란체(e.g. grain)의 평균 크기, D와 주파수 f와는 레일레이 산란 영역과 Stochastic 산란 영역에 대해 각각 $E_{B_S}\;\propto\;D^{3}f^{3}$와 $E_{B_S}\;\propto\;D\;f$인 관계를 가지는 것으로 얻어졌다. 이것은 액체/고체 경계면에서 레일레이각으로 입사되어 레일레이파로 전환된 초음파가 다시 액체로 그 에너지를 누설하여 그 산란 영역이 Schoch 변위 내에서 일어나기 때문이며, 이러한 영향에 의해서일반적인 산란에서의 주파수 의존성과는 달리 각 산란 영역에서 그 지수는 1씩 작은 값을 갖는다.향에 따라 음장변화가 크게 다를 것이 예상되므로 이를 규명하기 위해서는 궁극적으로 3차원적인 음장분포 연구가 필요하다. 음향센서를 해저면에 매설할 경우 수충의 수온변화와 센서 주변의 수온변화 사이에는 어느 정도의 시간지연이 존재하게 되므로 이에 대한 영향을 규명하는 것도 센서의 성능예측을 위해서 필요하리라 사료된다.가지는 심부 가스의 개발 성공률을 증가시키기 위하여 심부 가스가 존재하는 지역의 지질학적 부존 환경 및 조성상의 특성과 생산시 소요되는 생산비용을 심도에 따라 분석하고 생산에 수반되는 기술적 문제점들을 정리하였으며 마지막으로 향후 요구되는 연구 분야들을 제시하였다. 또한 참고로 현재 심부 가스의 경우 미국이 연구 개발 측면에서 가장 활발한 활동을 전개하고 있으며 그 결과 다수의 신뢰성 있는 자료들을 확보하고 있으므로 본 논문은 USGS와 Gas Research Institute(GRI)에서 제시한 자료에 근거하였다.ऀĀ耀Ā삱?⨀؀Ā Ā?⨀ጀĀ耀Ā?돀ꢘ?⨀硩?⨀ႎ?⨀?⨀넆돐쁖잖⨀쁖잖⨀／ࠐ?⨀焆덐瀆倆Āⶇ퍟ⶇ퍟ĀĀĀĀ磀鲕좗?⨀肤?⨀⁅Ⴅ?⨀쀃잖⨀䣙熸ጁ↏?⨀

In the context of knowledge sharing, network position has been a controversial subject. A central position in the network provides access to non-redundant knowledge, leading to more opportunities of knowledge sharing. On the other hand, as "bridging" relationships, its characteristics as a "weak tie" suggest innate lack of trust and reciprocity which is considered an impediment to share knowledge. This paper attempts to enlighten the underlying dynamic by examining the interaction between network centrality, motivation and ability in knowledge sharing. Furthermore, this paper examines the concept of knowledge sharing ability in depth by operationalizing the construct into three aspects: extensive and diverse knowledge, social media utilization ability and self-efficacy. The results show a partially supported three-way interaction, where the highest level of knowledge provision is reported when the employee has low network centrality, high autonomous motivation and high knowledge sharing ability, i.e. extensive and diverse prior knowledge. Though all models indicate strong associations between network centrality and knowledge sharing, this suggests an even greater power of motivation and ability that gives the strength to overcome unfavorable environments of peripheral position. Therefore, this paper offers an alternative explanation to the existing debate whether network centrality positively or negatively influences knowledge sharing.

The purpose of this study was to investigate how to develop of pre-service childcare teachers' perception about the image of childcare center teachers and self-image. In this study, participants' self-analysis method and in-depth interview were adopted to analyze the aspects of pre-service teachers' teacher image. Also, the narrative of pre-service teachers' a famous painting analysis were reported. The results of this study were divided into nine categories. Findings indicated that participants' self-image analysis work made pre-service teachers more enabled them to expend the significance of teacher's image of role in relation to their career decision and future their teacher's job. Moreover, through the experience of self-analysis work the pre-service teachers recognize their own ability to build up unique and healthy image. To foster the ability of pre-service teachers' self- image, special class teaching methods for pre-service teachers should be developed focusing on evoking them to have more positive self-image. This study suggested that self-image analysis work experiences should be emphasized in university class for pre-service teachers.

본 논문은 불어 명사의 의미 통사적 분류와 관련된 '대상부류(classes d'objets)' 이론을 바탕으로 한국어의 "크기" 명사 부류에 대한 의미적, 형식적 기준을 설정함으로써 자연언어 처리에의 활용 방안을 모색하고자 한다. 한국어의 일부 명사들은 어떤 대상 혹은 현상의 다양한 속성이 특정 차원에서 갖는 규모의 의미를 표현한다 예를 들어, '길이', '깊이', '넓이', '높이', '키', '무게', '온도', '기온' 등이 이에 해당하는데, 이들은 측정의 개념과도 밀접한 연관을 가지며, 통사적으로도 일정한 속성을 공유한다. 즉 '측정하다', '재다' 등 측정의 개념을 나타내는 동사 및 수량 표현과 더불어 일정한 통사 형식으로 실현된다는 점이다. 본 논문에서는 이러한 조건을 만족시키는 한국어 명사들을 "크기" 명사라 명명하며, "크기" 명사와 특징적으로 결합하는 '측정하다', '재다' 등의 동사를 "크기" 명사 부류에 대한 적정술어라 부른다. 또한 "크기" 명사는 결합 가능한 단위명사의 종류 및 호응 가능한 정도 형용사의 종류 등에 따라 세부 하위유형으로 분류할 수도 있다. 따라서 주로 술어와의 통사적 결합관계를 기준으로 "크기" 명사 부류를 외형적으로 한정하고, 이 부류에 속하는 개개 명사들의 통사적 세부 속성을 전자사전의 체계로 구축한다면 한국어 "크기" 명사에 대한 전반적이고 총체적인 의미적 통사적 분류와 기술이 가능해질 것이다. 한편 "크기" 명사에 대한 연구는 반드시 이들 명사를 특징지어주는 단위명사 부류의 연구와 병행되어야 한다. 본 연구는 한국어 "크기" 명사를 한정하고 분류하는 보다 엄밀하고 형식적인 기준과 그 의미 통사 정보를 체계적으로 제시해 줄 것이다. 이러한 정보들은 한국어 자동처리에 활용되어 "크기" 명사를 포함하는 구문의 자동분석 및 산출 과정에 즉각적으로 활용될 수 있을 것이다. 또한, 이러한 정보들은 현재 구축중인 세종 전자사전에도 직접 반영되고 있다.teness)은 언화행위가 성공적이라는 것이다.[J.
