위에서 살펴본 바와 같이 나는 급성 턱관절장애의 경우, 첫번째 유형은 주로 턱관절 디스크공간의 문제와 하악의 위치를 바로잡아주는 근육의 문제가 주 원인일 것으로 추정하고 있다. 만약 턱관절 디스크공간이 정상공간이라면 턱의 지그재그 움직임이나 턱관절잡음, 턱통증, 턱탈구, 그리고 개구장애 등이 발생할 수 없기 때문이다. 그리고 근육의 문제 중에서는 턱관절 디스크원판을 양측에서 잡아주는 내외측 익돌근의 문제가 가장 많은 영향을 미치고 있다. 특히 내측 익돌근의 긴장 및 수축이 디스크 원판을 내측으로 빠져나가게 함으로써 하악의 좌우 지그재그 움직임을 야기시키고 턱관절잡음이나 턱통증 및 개구장애를 유발하기 때문이다. 나머지는 저작에 관여하는 근육들이 그 다음으로 영향을 미치는 것으로 예측하고 있다. 그러나 제2형 급성 턱관절장애의 경우는 제1형 급성 턱관절장애가 한단계 더 발전하여 이와 연관된 근육이나 인대의 긴장수축이 오랜 시간 진행되어, 이들이 다시 상부 경추의 아탈구와 두개골의 비정상적 움직임에까지 영향을 미쳐 나타나는 것으로 생각된다. 그렇게 되면 뇌에서 필요 충분한 뇌혈액공급이나 뇌척수액순환의 문제를 일으킬 수 있기 때문이다. 그리고 제1형 만성 턱관절장애의 경우는 제2형 급성 턱관절장애가 좀 더 진행되면서 척추 및 근골격계의 구조변화, 교합 및 턱의 구조변화 그리고 안면구조의 변화에 이르기까지 점점 진행되어 나타나는 것으로 보인다. 따라서 각종 척추 디스크질환, 관절질환을 비롯해서 두개천골계의 순환문제, 부정교합 및 턱 비대칭, 안면 비대칭의 문제를 유발하게 된다고 추정된다. 그러나 두번째 유형의 만성 턱관절장애는, 턱에서 지속적이고 반복적인 그리고 과다한 부정적 자극들이 오랜 기간 누적되면서 턱에 분포된 C 섬유를 비롯한 3차신경의 가소성변화를 유발하면서 결국 중추신경계를 포함하여 전체신경계의 회로망에까지 파급되어 다양한 만성질환 또는 난치성 질환들이 양산되는 것으로 추정하고 있다. 아마도 지금까지 서양의학에서 아직 밝혀내지 못한 대부분의 질병들이 여기에 포함되지 않을까 하는 것이 나의 생각이다.

The purpose of this study is to investigate patient satisfaction for the spacial environment of the rehabilitative facilities, and by this to examine areas of patients' needs to develop patient-friendly improvement in spacial environment. 308 patients were surveyed at physical therapy centers of 6 hospitals or rehabilitative institutions in Daejeon with patient satisfaction questionnaire. The spatial environment satisfaction was categorized into 7 constructs and the data were statistically analyzed and compared by t-test and ANOVA according to the patient characteristics. As a result, inter-floor transfer was found to be the area with the least satisfaction, especially in the in-patient group. Locating floor level was the second lowest satisfied construct. Comfort was relatively highly satisfied construct overall, but patients with neurological disease had less satisfaction than with musculoskeletal disease. Patients in 20's were less satisfied in wayfinding than 60's. Satisfaction for interior design was lower in subject in 50's than 70's. These findings can be used as evidences to improve spacial environment design for rehabilitative facilities to the better patient satisfaction.

Family films with insight of the society are now recognized as significant texts to communicate with audience from the beginning of the history of film and to reflect various viewpoints on changes of the times and socio-cultural context. In such aspect, the films of Hirokazu Kore-eda are very significant in that they suggest very sharp view on modern society through family narrative. His family narratives not only presented a profound reflection on the modern society and human relations through themes on death, loss, severance, and alienation, but also formed a public sympathy based on success in the box-office numbers despite his heavy subjects. His such achievement is closely related to the format of spatial representation to record 'time' and 'daily life' as well as the family film as a narrative form to draw the meaning of a family. Therefore, this study analyzes the family narrative and the format of spatial representation in the films of Hirokazu Kore-eda, and could find the film form where life and space closely communicate each other to reach the topic. This study, concentrating on the spatial representation and the roles and meanings of formal factors in family narrative, can find its own value in its expansion out of the previous studies which adopted macro perspectives on the trend of the times.

In cases of densely occluded urban scenes, it is effective to determine the visibility of scenes, since only small parts of the scene are visible from a given cell. In this paper, we introduce a new visibility preprocessing method that efficiently computes potentially visible objects for volumetric cells. The proposed method deals with general 3D polygonal models and invisible objects jointly blocked by multiple occluders. The proposed approach decomposes volume visibility into a set of point visibilities, and then computes point visibility using hardware visibility queries, in particular HP_occlusion_test and NV_occlusion_query. We carry out experiments on various large-scale scenes, and show the performance of our algorithm.

21세기는 과학적 물질문명의 발달로 인하여, 과거에는 느껴보지 못했던 물질문명의 풍요를 이끌어 냈으며, 컴퓨터, 메스미디어의 발달로 인하여, 인간 문명의 관심은 지구계를 벗어나 우주론적으로 확장되어 마침내 우주시대를 열었다. 하지만 인간의 이성과 함께 영원하리라 믿었던 과학적 합리성은 20세기 초두에 제국주의적 전쟁을 일으키게 되었으며, 그로 말미암아 이성 파괴 현상이 드러나게 되었다. 급기야 20세기말에 이르러 다원주의라 칭하기도 하는 후기산업사회의 병적 증후군들, 국가간의 경제전쟁, 컴퓨터 및 각종 정보매체를 통한 신속한 정보교환의 이면에는 인간의 자기정체성의 혼돈을 아울러 초래하게 되었다. 과학기술의 발달로 생태계 및 환경은 오염되고 파괴되었다. 20세기말에는 산성비, 엘니뇨, 라니냐 현상으로 인하며, 환경의 재앙을 초래하면서 이제 인간은 문명에 대하여 여태껏 가져왔던 확고한 믿음에 회의를 갖게 된 것이다. 이와 같은 현상은 인간의 주체적 인식과 과학적 믿음의 지나친 숭배로 인하며 자연도 인간에 의하여 지배되고 인간을 위해서만 존재하는, 인간과 자연의 이원론적인 생각 즉, 인간의 이성에 의해서만 가능하다고 생각한 "근대적 주체"에 대한 맹신의 결과인 것이다. 이렇듯 20세기의 문제점은 21세기로 전가되어 여전히 계속되고 있으며, 세계내의 가장 큰 문제점은 전쟁, 기아 등 보다 이제는 오히려 환경. 생태문제로 귀결되어 지구의 생존권 자체가 위협을 받게 되었다. 미술도 서구문명의 근대주의적 영향에 의해서 모더니즘 등 이성위주의 미술인 "근대 주체적 미술"로 발전하였지만 포스터모더니즘에서 보여 지듯 이미 인간의 순수한 이성을 근간으로 한 미술에 있어서의 주체성 주장은 상당부분 무너졌으며, 이제는 장르의 해체와 다원화 현상으로 나아가게 되었다. 환경파괴에 직면하여 이제 주체는 자연이라는 타자를 새롭게 등장시킨다. 그리하여 생명중심주의, 전체론, 감각 중심주의 등 인간과 자연이 함께 공생하는 자연을 향한 생태적인 미술이 절실히 요구되는 것이다. 이에 본 연구논문은 무비판적 서구미술에 동요되지 않고, 지극히 자연적이고 동양적이기도 한 끊임없이 생명력을 창출해 내는 자연에 관심을 같게 되었으며, 환경의 중요성과 함께 생태학적 미술, 즉 생태미술에 본인의 작업을 관계시키고자 한다. 근대적 문명사에 의해 매장된 생태적 유기성의 흔적을 고고학적 탐사방법을 통하며 발굴해 내며, 환경윤리와 생태학, 심층 생태학, 북친의 '사회 생태학'을 수용하여 물질성의 생태적 복원과 함께 조형공간의 다원성에 대한 생태 미술의 일단을 규명코자 하였다.

Creative environment for sales that a company's image can be effectively delivered to consumers increases consumption desirability and puts confidence in products. Thus, it can be resulted in increasing company's profit. However, nowadays commercial spaces do not show their differences from others due to an excessive competition. Therefore, groping a differentiated composition for commercial spaces should be importantly considered because consumers wants to meet their own individuality in the fashion speciality store. The purpose of this paper is in present the way of differentiating images for commercial spaces. In order to investigate, the role of a wall in commercial spaces should be reconsidered. The concept of a wall in fashion store in the past was understood as one of the structures in the building and a place that displays commodities for sales. However, this paper introduces a new concept of a wall as an important visual function in the fashion store. In other words, the new concept emphasized functions and compositions of a wall in the perspective of symbolic and visual sides, instead of a physical side. Moreover, this paper presents the relationship between the internal side of a wall which has a high frequency of visually and the external side of a wall which has a signaling effect to the consumers. Finally, this paper shows effective way of expressing company's image in the fashion store by adopting the new concept of a wall composition.

Convergence Confinement Method (CCM) makes a more simple judgement in a ground-support reaction than numerical method. Also this method is good for the applicability of construction feedback and the analysis of field measurement. However, there has been little research with respect to the application of CCM in tunnel construction. One of the problems in CCM is a decision of the time to support installation. To decide a reasonable supporting installation time, support characteristic curve and displacement characteristic curve considering construction stage are proposed. In addition, to predict displacement distribution ratio and load distribution ratio, the time dependent support reaction curve is used. Finally, through a comparison of the result between CCM and numerical analysis, the trust of this study is proved and the practical application is proposed to control resonable tunnel construction management.

The most significant difference of embedded systems from general purpose systems is that embedded systems are allowed to use only limited resources including battery and memory. Especially, the number of applications increases which deal with multimedia data. In those systems with high data computations, the delay of memory access is one of the major bottlenecks hurting the system performance. As a result, many researchers have investigated various techniques to reduce the memory access cost. Most programs generally have locality in memory references. Temporal locality of references means that a resource accessed at one point will be used again in the near future. Spatial locality of references is that likelihood of using a resource gets higher if resources near it were just accessed. The latest embedded processors usually adapt cache memory to exploit these two types of localities. Processors access faster cache memory than off-chip memory, reducing the latency. In this paper we will propose the enhanced dynamic allocation technique for structure-type data in order to eliminate unused memory space and to reduce both the cache miss rate and the application execution time. The proposed approach aggregates fields from multiple records dynamically allocated and consecutively remaps them on the memory space. Experiments on Olden benchmarks show $13.9\%$ L1 cache miss rate drop and $15.9\%$ L2 cache miss drop on average, compared to the previously proposed techniques. We also find execution time reduced by $10.9\%$ on average, compared to the previous work.
