Abstract Background and study aims Ultrathin endoscopes are commonly used for surveillance esophagogastroduodenoscopy (EGD) to reduce discomfort associated with scope insertion. However, the flexibility of an ultrathin endoscope is a trade-off between reducing discomfort and lengthening examination time. Patients and methods The EG17-J10 (EG17) is a novel ultrathin endoscope characterized by its tapering body stiffness; however, the flexibility of its tip is comparable to that of the traditional ultrathin endoscope EG16-K10 (EG16). We compared EGD examination time between EG17 and EG16. A total of 319 examinees who underwent EGD from November 2019 to January 2020 at the Chiba-Nishi General Hospital were enrolled. Six examinees were excluded due to past history of surgical resection of the upper gastrointestinal tract or too much food residues; 313 examinees (EG17, 209; EG16,104) were retrospectively analyzed. The examination time was divided into three periods: esophageal insertion time (ET), gastroduodenal insertion time (GDT), and surveillance time of the stomach (ST). The total amount of ET, GDT, and ST was defined as total examination time (TT). Results TT of EGD using EG17 was significantly shorter compared to EGD using EG16 (222.7 ± 68.9 vs. 245.7 ± 78.5 seconds) (P = 0.004). Among the three periods of examination time, ET (66.7 ± 24.1 vs. 76.0 ± 24.1 seconds) (P = 0.001) and GDT (47.9 ± 17.4 vs. 55.2 ± 35.2 seconds) (P = 0.007) of EGD using EG17 were significantly shorter compared to EGD using EG16, except for ST (108.1 ± 51.5.1 vs. 114.5 ± 50.1 seconds) (P = 0.148). Conclusion An ultrathin endoscope with tapering body stiffness can shorten EGD examination time, mainly due to the shortening of insertion time.

<p>In Haruki Murakami’s Hard-Boiled Wonderland and the End of the World, reality and imagination are infused in an interplay of narratives. The story is about discovering the identity of Self, using a walled city as a metaphor for the subconscious. The novel weaves the stories of two characters, the external self and the internal self, each chapter flicking between the real and the dream, from conscious to unconscious. Murakami provides the reader with a contemplation on the nature of existence, being versus non-being. Dr William S Haney, Professor of Literary Theory and specialist on culture and consciousness, argues that the shadow in Murakami’s allegory is a representation of the mind. As the narrative unfolds, the shadow—stripped from its owner—slowly dies, causing loss of memory, emotion and desire. The relinquishing of one’s shadow in the allegory suggests a loss of the metaphysical aspect of Self. The Shadow is not merely seen as an immaterial entity; rather it is the sign of full corporeality. The Shadow grants meaning to existence, illuminating the reality that we cannot perceive the light without the darkness.  This thesis is born out of a concern for the dearth of meaning in architecture in an age of uncertainty. In the modern contemporary sphere, we have become obsessed with the image, with rationalistic tendencies; with evermore light and luminosity, architecture has primarily been caught up in trying to order and rationalise the world. In this condition of objectification and reduction, architecture risks falling into a trap of homogeneity, thereby limiting itself to an empty datum of quantification. Thus, the unhygienic, the disorder and the chaos, the darkness that grants life its pungency, have been ‘relegated to the shadows’. Roberto Casati, senior researcher and Professor of Philosophy at the Centre National de la Recherche Scientique and an authority on shadow perception, argues that shadows avoid direct reading: “[t]he interaction of the two unequal brothers has been described in different ways, from the notion that shadows are ‘holes in the light’ through to the opposite idea that they are ‘the remaining representatives on earth of the cosmic darkness, otherwise torn apart by light’”. Viewed in this sense, Shadows can be seen as both corporeal operation—bound to the physical cycles of earth, moon and sun—and metaphysical entity, alluding to the primordial darkness before the birth of light and matter.  The allegory of the Shadow in Hard-Boiled Wonderland can be seen as a rumination on the loss of the metaphysical aspect of Self in a contemporary cybernetic age. In Murakami’s novel, the shadow cannot enter the walled Town; it must be left behind in the Shadow Grounds, the threshold between inner and outer realms. The Gateway, as described in Murakami’s novel, becomes the provocateur for this thesis. Interpreting Murakami’s architectural and allegorical program of the Gateway and Shadow Grounds in relation to Penelope Haralambidou’s seminal article “The Allegorical Project: Architecture as Figurative Theory”, this design-led research investigation interrogates the use of the Allegorical Architectural Project as a critical method. Allegory provides a structure of thought whereby meaning is not grasped immediately, but rather through progressive discovery and continual interpretation of its ambiguous traits. Ambiguity in architecture has the ability to appear ever-changing, resist resolution and remain open to interpretation.  The methodology of the investigation explores the spatial realm of the shadow through the critical and creative process of drawing. The principal aim of this thesis is to journey into the darkness, to embrace the shadow of the unknown, searching for a space in-between—between light and shadow, architecture and art, reality and fiction, the constructed and the imagined. Using Haruki Murakami’s Hard Boiled Wonderland and The End of the World as a generator and provocateur, the research employs the notion of the shadow as both mythological entity and corporeal signifying process. Rather than seeking concrete conclusions, it posits a speculative allegorical architectural project that invites critical engagement and interpretation. It argues that architecture occupies the liminal position between darkness and light, the true place of human existence, and as such, the design of Shadow is essential to the meaningful design of architecture.  The thesis investigation asks: how can the speculative architectural drawing be used as a means of interrogating the realm, and enhancing our awareness of, the shadow in architecture?</p>

Architecture and light are to that extent dependent on each other which body and spirits are.One for living and the other for physical presence in this world needs the other and while light is flown on the body of the space both two perceptible worlds become “ existed “.Since long ago, bright and shimmering materials which remind something living in the mind of individual were respectable and adorable. Being aware of the process of exploitation of sunlight is of importance as much as the process of materials formation or different fundamental forms of construction in order to design. Almost in all religions, light is the symbol of Devine wisdom and the Essene of all beneficence and purities and mobility from darkness to light, was considered as the main objective. Islamic Mosques which are ornamented with light are perfectly able to transmit this divine and moral sense. In such spaces which are lighten up with a shimmering light and by observance of the imprecise shadows of substances and masses, individual starts to complete the pictures in his mind and by such an activity gets in to an ecstasy and as a result a feeling of getting close to the source of existence and reality wakens up inner inside him. The present survey by depending on descriptive-analytic methods, studies light in Islamic and traditional architecture. This paper by case study of Sheikh Lotfollah Mosque, aims to find out whether the presence of light and specifically natural light in architecture might have further meaning rather than brightness, and whether accessing an accurate pattern of application of light is possible or there is basically no compulsion in it ?

"The architecture of Markus Wespi, Jérôme de Meuron and Luca Romeo generally seeks a close connection to its surroundings and the local building culture; the architects look for clues in the existing culture and tradition. They are interested in the combination of traditional and modern elements, which together form a new unity and push the historical development forward. In their projects, they seek to achieve a certain timelessness; the combination of traditional materials with new elements creates a natural self-evidence that integrates the familiar and the new, thus being able to continue to develop and survive in the future. In mountainous and sloping locations, buildings have an enormous impact on the landscape and should therefore be integrated carefully with it in both form and materials, rather than simply benefitting from it thanks to large viewing windows. We like the concept of a new building which seems to have been there for a long time, whose natural materials have developed a patina which makes them even more beautiful. We are particularly fascinated by its atmosphere, light and shadow."
