The use of relaxing cosmetic products is more and more widespread on the self care market, since stress is considered as a major cause of discomfort in modem life. Cortisol, the stress hormone, helps the human body to regulate itself by acting on carbonhydrate, proteins and fat metabolisms. IgA are immune molecules involved in the stress response of the human body. The less the human body is stressed, the more the salivary IgA rate increases. Salivary cortisol and IgA have the advantage of being easily assessed with non invasive methods. Finally, conductance is the measurement of the modification in the electrical resistance of the skin. By this means, the measurement of the conductance enable the assessment of somebody's stress.(omitted)

Objective : We assessed the effectiveness of a mindfulness-based intervention in improving positive psychological resources in older people who were affected by the Jeju 4·3 incident. Methods : This study included 25 older people recruited from the Jeju 4·3 Trauma Center. The intervention was conducted on a once-a-week basis for six weeks. All participants completed self-report questionnaires, including the Five Facet Mindfulness Questionnaire Short Form (FFMQ) and Positive Resources Test (POREST). Results : This intervention significantly improved the total score and the nonreactivity, observing, acting with awareness, describing, and nonjudging of inner experience FFMQ scores. The interventions also significantly improved the POREST subscale scores. Conclusion : The mindfulness-based intervention significantly improved positive psychological resources in older people exposed to the Jeju 4·3 incident.

자동차의 자율주행 기술이 확대되면서 '눈'의 역할을 하는 센서가 점차 중요시되고 있다. 최근 차량에 장착되는 라이다 센서는 채널이 많을수록 피사체에 반사된 신호 또한 풍부해짐에 따라 장애물, 지형, 차량 등 주변 환경 탐색의 정확도가 높아진다. 하지만, 라이다 센서는 채널 증가에 따른 열배 이상 가격의 차이가 있으며, 이러한 가격적인 문제로 보급형 차량보다는 고가의 차량에만 부분적으로 사용되고 있다. 본 연구는 저 가격의 16 채널의 라이다를 복수개로 구성하여 동시에 신호를 수집 처리하여 하나의 입체공간으로 융합하고 이를 나타낼 수 있게 함으로써 64 채널의 라이더와 같은 효과를 나타낼 수 있게 하였다. 이를 통해서 차량 심미성의 개선과 함께 보급화를 위한 기반을 제공할 수 있다.

This thesis examines the term a performer's sincerity taking into consideration issues of the bodily engagement and specifically addressing the place of a performer's respiration. The main emphasis in this research will be on the tendency to a performer's anticipation in contrast to a state of being in the moment on stage. Exploring and reconsidering the process of training the performer's body reminds us the significance of rigorous training in an appropriate way(s) within which the performer's body enables to meet the principles of acting with the nature of theatre as his/her body is responding and subordinating to the moment on stage. Here, this thesis argues that we need to acknowledge that initiating any bodily movement has to understood and then inhabited by negating a performer's active willingness where the source of energy, breathing roots, then transfers through the entire body rather than the mere use of the external forms or muscles. To be precise, maintaining the internal energy through the moment informs how the performer interrogates where and what s/he is in a state of whole body engagement preventing the performer's self-doubt about what s/he is doing in the next moment(s). The process should be considered as a qualitative bodily shift gazing into his/her inner territory to reach behind a linguistic and/or an intellectual sense. The research finding suggests that a performer's art is to allow the animating respiration in order to facilitate and enliven his/her entire body as oneness which in turn moves his/her scene partner(s) as well as the spectator in the here and now.

This thesis explores the embodiment of a performer and a character/role specifically by examining what the term character is associated with and implies in a sense of the performer's bodily training through which what happens to their body. First of all, this research begins to investigate the relationship between a performer and a character centred on the performer's bodily experience through training and/or studio work. From a perspective of a performer, the concept and practical approach of a character itself essentially includes and signifies all the given circumstance of a specific play which has to be acknowledged then inhabited through the performer's body. That is, the internal structure of the text parallels with articulating and developing the spine of a specific character which take place as the substance leads the performer's body to an organic action and/or that of way corresponding to what the character needs and wants to obtain through a series of moment on stage. Here, we argue that the purposeful action as a process and result of applying/inhabiting the substance enhances the performer's body as the whole being participates in the given environment within which his/her body can also work or function by means of the integrated oneness. Second, in a manner of the most fundamental level, both the ethic of acting and the central task of a performer remind us the significance of allowing therefore experiencing subtle bodily movement, namely, responses to stimulus from in/outside of his/her body either visible or invisible on the one hand. At the same time, such a journey of self-discovery empowers the performer to explore new potential possibilities on the other. Finally, as the research finding suggests that these practical insights are necessarily need to be acknowledged as a point of the departure through which the quality of a performer's body is also cultivated by means of the changeable wholeness in order to being on stage.

We investigated the carbon monoxide (CO) gas-sensing properties of nanostructured Al-doped zinc oxide thin films deposited on self-assembled Au nanodots (ZnO/Au thin films). The Al-doped ZnO thin film was deposited onto the structure by rf sputtering, resulting in a gas-sensing element comprising a ZnO-based active layer with an embedded Pt/Ti electrode covered by the self-assembled Au nanodots. Prior to the growth of the active ZnO layer, the Au nanodots were formed via annealing a thin Au layer with a thickness of 2 nm at a moderate temperature of $500^{\circ}C$. It was found that the ZnO/Au nanostructured thin film gas sensors showed a high maximum sensitivity to CO gas at $250^{\circ}C$ and a low CO detection limit of 5 ppm in dry air. Furthermore, the ZnO/Au thin film CO gas sensors exhibited fast response and recovery behaviors. The observed excellent CO gas-sensing properties of the nanostructured ZnO/Au thin films can be ascribed to the Au nanodots, acting as both a nucleation layer for the formation of the ZnO nanostructure and a catalyst in the CO surface reaction. These results suggest that the ZnO thin films deposited on self-assembled Au nanodots are promising for practical high-performance CO gas sensors.

Injectable chitosan hydrogels have attracted great potential due to sustained-release property and safety. Here, palmityl-acylated glycol chitosan (Pal-GC) was used to generate physically cross-linked hydrogels by virtue of hydrophobic attraction of linear fatty carbons. Glycol chitosan was chemically modified with N-hydroxysuccinimide-activated palmitic acid in dimethylsulfoxide (DMSO) containing dimethylaminopyridine. Through a series of preparation steps of (i) dialysis with DMSO, (ii) addition of palmityl-acylated exendin-4 (Ex4-C16), and (iii) dialysis with water, Pal-GC was self-assembled to form physically cross-linked hydrogels entrapped with Ex4-C16. The Pal-GC derivative was analyzed by using 1H NMR, and the surface morphology of Pal-GC hydrogels formed was examined by scanning electron microscopy. Also, the hypoglycemic effect induced by Pal-GC hydrogels containing Ex4-C16 (250 nmol/kg) was evaluated in non-fasted type 2 diabetic db/db mice and compared with GC hydrogels containing native Ex4 at the same dose. Results showed that palmityl group was successfully conjugated with the amines of glycol chitosan, and that Pal-GC efficiently generated the hydrogels formation. Moreover, Pal-GC hydrogels containing Ex4-C16 was found to greatly prolong the hypoglycemia duration (~ 4 days). This was due to the dual-functions of the palmityl groups present in both GC and exendin-4 such as hydrophobic attraction and plasma albumin-binding. We consider this new type of self-assembled GC hydrogels loaded with Ex4-C16 would be a promising long-acting sustained-release system with anti-diabetic property.

본 연구에서는 CADMAS-SURF 모형을 사용하여 케이슨 직립제의 상부에 패러핏의 설치 위치에 따라서 규칙파에 의한 파압과 파력의 특성을 분석하였고, 파력결과를 사용하여 방파제 및 지반 안정성 평가를 수행하였다. 수치해석결과, 후부 패러핏을 채택하면 전면 최대 파압 및 파력을 저감시킬 수 있으며, 패러핏에 작용하는 최대 파압은 전면에 있는 경우에 비하여 다소 증가하나 전면 최대 파압과의 위상차에 의해 방파제의 안정성에는 거의 영향을 미치지 못함을 확인하였다. 그리고 Yamamoto et al.(2013)이 후부 패러핏의 문제점으로 지적한 바 있는 충격파압은 발생하지 않았다. 활동, 전도에 대한 안정성 검토 결과, 후부 패러핏 구조를 채택하면 항외측에 패러핏을 설치한 경우에 비하여 13% 적은 자중으로도 목표 안전율인 1.2를 확보할 수 있는 것으로 평가되었다. 이때 최대 지반지지력도 30% 감소되는 것으로 확인되어 후부 패러핏 구조의 실제 현장에서의 적용성이 높은 것으로 평가되었다.

얕은 터널의 개착식 터널 라이닝에 발생하는 과잉토압은 라이닝의 변형과 손상을 유발하는 역학적 주요인자들 중의 하나이며(Kim, 2000), 과잉토압은 되메움토의 다짐불량, 자중에 의한 압밀, 강우의 침투에 의한 다짐, 차량에 의한 진동 등에 의해 발생할 수 있다(Komiya et al., 2000; Taylor et al., 1984; Yoo, 1997). 터널 라이닝에 발생하는 토압을 구하기 위한 많은 시험이 행해졌지만, 부등침하와 과잉토압을 줄일 수 있는 보강대책을 수립하기 위한 사례는 없다. 본 연구는 모래 지반에 $1.0D\sim1.5D$ 깊이에 개착식으로 시공하는 원형의 강성 터널에 작용하는 토압에 관한 것으로 진동다짐의 영향을 모형실험에서 충분히 반영하기 위하여 100Hz의 진동주파수를 사용하였다. 본 연구에서는 개착식 터널 라이링에 작용하는 부등침하와 과잉토압을 줄이기 위해서 지오텍스타일 매트를 설치하였다. 지오텍스타일 매트의 보강에 의한 부등침하와 토압의 감소효과를 확인하기 위해 실내모형실험을 수행하였다. 실내모형실험에서 토피, 매트 보강형태, 절취면의 거칠기 등을 달리하여 가장효과적인 방법을 구하였다. 절취면의 거칠기 달리하기 위해 사면에 사포#100, 사포#400과 acetate 부착하였습니다. 무보강과 매트 보강에 대한 모형실험을 실시하여 구한 토압을 비교하여 매트 보강효과를 살펴보았으며, 사진분석법(Park, 2003)을 이용하여 지반의 변형을 분석하였다.
