A blazed $GxL^{TM}$ device is described as having high optical efficiency (> 70% for RGB lasers), and high contrast ratio (> 10,000:1), and that is highly reliable when used in a large-area laser projection system. It has a robust design and precise stress control technology to maintain a uniform shape (bow and tilt) of more than 6,000 ribbons, a $0.25-{\mu}m$ CMOS compatible fabrication processing and planarization techniques to reduce fluctuation of the ribbons, and a reliable Al-Cu reflective film that provided protection against a high-power laser. No degradation in characteristics of the GxL device is observed after operating a 5,000- lumen projector for 2,000 hours and conducting 2,000 temperature cycling tests at $-20^{\circ}C$ and $+80^{\circ}C$. At the 2005 World Exposition in Aichi, Japan the world's largest laser projection screen with a size of 2005 inches (10 m ${\times}$ 50 m) and 6 million pixels (1,080 ${\times}$ 5,760) was demonstrated.

1. Objectives This study is for discovering the characteristics of the sleep in ordinary symptoms based on the Sasang Constitution. The result of this study could be helpful to understand and to identify the patients as Taeumin by contrast with non-Taeumin. 2. Methods There were 1,229 patients(529 men), who answered the questionnaire about their ordinary sleep patterns. They had been diagnosed, including their Sasang Constitution, by the Sasang Constitution specialist at Bundang Oriental Hospital of Dongguk university. Applying the binary logistic regression analysis to each item about ordinary sleep patterns and the diagnosed Sasang Constitution, we can measure the characteristics and influence of ordinary sleep patterns to the dependent variable(Sasang Constitution). 3. Results As a result of the binary logistic analysis on the observed questionnaire, we found the similar features of the ordinary sleep patterns on Taeumin by contrast with non-Taeumin. In order of influence that identify Taeumin or non-Taeumin, first, Taeumin has a tendency that he will snore well or frequently. Second, Taeumin has a tendency that he will not dream, when he sleeps by contrast with non-Taeumin. 4. Conclusions This study will be used to identify patients as Taeumin or non-Taeumin by means of a reference tool.

We have attached importance to the values of spirit and immateriality. As the age of modernism of rationality ended, human being began to emphasize spiritual and immaterial while accepting multiplicity and diversification in the whole areas of society and culture. Hence interests have increased in another side of human spirit that was oppressed by rational, analytic, reasonable and scientific thinking, which has expanded the inner world of human being to the world of the unconscious. According to these paradigm changes, steady efforts to improve our lives better both materially and spiritually have been made in the areas of art and design. Therefore, the current study aims to examine the meaning of object expressed in space from the viewpoint of the unconscious, focusing on works of designer Philippe Starck after 2000 in which unique, preferential and liking characteristics are expressed well. Philippe Starck is a designer who connects design with our daily lives and formalizes it with creative ideas. Also the study theoretically explored the theory of the unconscious, a concept of Freudianism, based on 'Meaning of Dreams' of Freud, and explained the expressional characteristics and meaning of unconscious desire through his works by putting object in Philippe Starck's space. It aims to grope for the meaning of object as another possibility that can function as a spatial ruling element by analyzing object through expanding the extent of correlation and interpretation between human containing spiritual things and object which is the recognition subject in space of the present time, not a mere concept as substance like in the past, and expression of Starck's unconscious desire based on unconscious theory.

Purpose: This study investigated the effects of virtual reality-based task training (VRBTT) using a smart glove on upper extremity function and activity of daily living in stroke patients. Methods: Twenty-nine patients with chronic stroke disease were randomly allocated to two groups: the VRBTT group (n=14) and the control group (n=15). All patients received 30 minutes of standard occupational therapy, 5 times a week, for 8 weeks. The VRBTT group performed an additional 30 minutes of virtual reality-based rehabilitation training, 5 times a week, for 8 weeks. Results: Both groups showed significant improvements in upper extremity function, yielding an increase in FMA and K-WMFT (p<0.05). There was a more significant increase in the VRBTT group before and after interventions (p<0.05). There was no significant difference in MAS for the control group (p>0.05); however, there was a significant increase for the VRBTT group (p<0.05). In the activities of daily living, there was a significant difference in the values for K-MBI (p<0.05). In addition, both groups showed a significant increase for K-MBI and K-RNLI (p<0.05). Conclusion: This study showed that VRBTT using smart gloves can have a more positive effect on upper extremity function and activities of daily living in stroke patients than conventional intervention methods. A variety of virtual reality-based contents and glove-shaped wearable devices will help stroke patients in rehabilitation clinics recover and return to society.

1920년대를 다룬 피츠제럴드의 소설 "위대한 개츠비"를 루어먼은 2013년 영화로 재현하고 있다. 소설에서는 독자가 플롯을 통해 자신의 상상력으로 이야기의 흐름을 파악해야 하지만, 영화 는 소설의 요소에 시청각적인 효과를 융합시키고 있다. 데이지는 패션의 아이콘으로 그녀가 입고 있는 프라다, 샤넬, 그리고 티파니 같은 보석은 재즈 시대의 의상을 현대적인 감각으로 재현하여 관객들에게 볼거리를 제공하면서, 내용을 더욱 잘 이해할 수 있도록 도와주고 있다. 또한 영화에서 시사하고 있는 "재의 계곡", "초록 불빛", "이스트 에그", "웨스트에그"와 같은 그 지역이 주는 상징들은 좀 더 직접적이다. 컴퓨터 그래픽으로 만들어진 개츠비 대저택에서 주말마다 열리는 광란의 파티는 정신적인 혼란과 물질적인 풍요라는 시대적인 분위기를 잘 반영해 주고 있다. 여기에 배우들의 명연기가 소설의 주제를 잘 부각시켜줌으로서 영화로의 융합은 소설을 좀 더 대중적인 예술로 승화시키고 있다. 이러한 것들을 인터넷 자료를 통해 좀 더 체계적으로 살펴본다.

본 연구의 목적은 남자 대학생들의 스포츠토토 도박을 통해 겪게 되는 경험과 그들이 당면하고 있는 문제를 파악하여 남자 대학생 도박중독의 예방 및 회복 프로그램에 기초자료를 제공하고자 시도하였다. 본연구의 참여자들은 8명의 남자 대학생으로 심층 인터뷰 한 자료를 Colaizzi의 현상학적 연구방법에 따라 분석하였다. 연구결과 경험의 범주는 4개로 바다로 달려가는 바람처럼, 회한으로 흐르는 눈물, 수면 아래로 잠긴 삶, 꿈을 꾸는 날엔 으로 도출되었다. 본 연구를 통해 스포츠토토는 접근성이 용이하고 흥미 유발적인 요소가 많지만, 일반 도박자들과 마찬가지로 자기 통제력을 상실한 채 중독에 빠질 위험이 크다는 것이 드러났다. 그렇지만 도박 기간이 짧은 대학생이 경제적 자금 조달의 한계점으로 현실을 자각할 경우 도박중독 위험으로부터 비교적 빠르게 격리될 수 있다고 본다. 따라서 스포츠를 좋아하는 대학생들을 위한 도박 예방교육과 상담이 필요할 것으로 생각된다.

The introduction of checkpoint inhibitors revolutionized immuno-oncology. The efficacy of traditional immunotherapeutics, like vaccines and immunostimulants was very limited due to persistent immune-escape strategies of cancer cells. Checkpoint inhibitors target these escape mechanisms and re-direct the immune system to anti-tumor toxicity. Phenomenal results have been reported in entities like melanoma, where no other therapy was able to demonstrate survival benefit, before the introduction of immunotherapeutics. The first experience in ovarian cancer (OC) was reported for nivolumab, a fully human anti-programmed cell death protein 1 (PD1) antibody, in 2015. While the data are extraordinary for a mono-immunotherapeutic agent and very promising, they do not match up to the revolutionary results in entities like melanoma. The key to exceptional treatment response in OC, could be the identification of the most immunogenic patients. We hypothyse that BRCA mutation could be a predictor of improved response in OC. The underlying DNA-repair-deficiancy should result in increased immunogenicity because of higher mutational load and more neoantigen presentation. This hypothesis was not tested to date and should be subject to future trials. The present article gives an overview of the immunologic background of checkpoint inhibition (CI). It presents current data on nivolumab and other checkpoint-inhibitors in solid tumors and OC specifically and depicts important topics in the management of this novel substance group, such as side effect control, diagnostic PD-1/programmed cell death-ligand 1 (PD-L1) expression assessment and management of pseudoprogression.
