새롭게 등장하고 있는 플렉서블 디스플레이 인터페이스는 형태의 물리적 변화가 일어나는 인터페이스로써, 인터페이스의 물리적 형태는 핵심적인 사용자 경험 디자인 요소가 된다. 이에 본 연구는 플렉서블 디스플레이의 물리적 특성을 드러내는 형태 요인을 도출하고자 하였으며, 이를 위해 기존의 디자인 문헌과 플렉서블 디스플레이 인터페이스 문헌연구에 나타난 형태요인을 정리하였다. 또한 본 연구에서는 형태 요인의 수준에 따라 사용자 경험에 영향을 미칠 것으로 보고, 문헌에 나타난 수준의 분류를 통해 사용 용도나 사용 경험에 차이를 가져올 것으로 판단되는 요인 값을 인용하여 사례와 함께 제시하였다. 본 연구에서 도출된 플렉서블 디스플레이 형태요인은 모양(Shape), 유연성(Flexibility), 크기(Size), 다중 표면(Multi-Surface), 질감(Texture), 투명(Transparency)의 6가지이다. 이때 모양의 요인 값은 2.5D와 3D의 기하학적 원형을 중심으로 한 8가지 수준의 값, 유연성은 곡률반경을 중심으로 5가지 수준의 값, 크기는 휴대할 수 있는 정도의 초소형에서부터 공공장소에서 사용할 수 있을 만한 대형까지 4가지 수준의 값, 다중표면은 연속된 경우와 불연속된 경우로 나누고 이것을 분리된 면의 수로 나눈 5가지 수준의 값, 질감은 시각, 촉각, 시촉각의 3가지 수준의 값, 그리고 마지막으로 투명은 배경 사물을 인지하는 수준과 관련하여 3가지 수준의 값으로 정리되었다. 본 연구에서 제시된 형태 요인과 값들은 향후 사용자 경험과의 관계에 대한 실증적 연구의 기초자료로 활용될 것이다. The newly emerging flexible display is the interface of which physical form could be chanced. This paper shows the form factors of the flexible display interface and their factor values on the basis of understanding that the physical form is one of the most important parts that could affect user experiences. The form factors of the flexible display interface shown in this paper are Shape, Flexibility, Size, Multi-Surface, Texture and Transparency. Shape is divided into 8 factor values based on the geometric primitive. Flexibility is divided into 5 factor values based on the Rbending value. Size is divided into 4 factor values based on not only size itself but also the user context. Multi-Surface is divided into 5 factor values based on the number of the divide surfaces and their continuity. Texture is divided into 3 factor values based on the tactility and visuality. Finally, transparency is divided into 3 factor values based on the clarity of object through the display.

Little human tissue data are available for slow waves and migrating motor complexes, which are the main components of small bowel motility. We investigated the electrophysiological and mechanical characteristics of human ileal motility, in vitro. Ileum was obtained from patients undergoing bowel resection. Electrophysiological microelectrode recordings for membrane potential changes and mechanical tension recordings for contraction from smooth muscle strips and ileal segments were performed. Drugs affecting the enteric nervous system were applied to measure the changes in activity. Slow waves were detected with a frequency of 9~10/min. There were no cross-sectional differences in resting membrane potential (RMP), amplitude or frequency between outer and inner circular muscle (CM), suggesting that electrical activities could be effectively transmitted from outer to inner CM. The presence of the interstitial cell of Cajal (ICC) at the linia septa was verified by immunohistochemistry. Contractions of strips and segments occurred at a frequency of 3~4/min and 1~2/min, respectively. The frequency, amplitude and area under the curve were similar between CM and LM. In segments, contractions of CM were associated with LM, but propagation varied with antegrade and retrograde directions. Atropine, $N^W$-oxide-L-arginine, and sodium nitroprusside exhibited different effects on RMP and contractions. There were no cross-sectional differences with regard to the characteristics of slow waves in CM. The frequency of contractions in smooth muscle strips and ileal segments was lower than slow waves. The directions of propagation were diverse, indicating both mixing and transport functions of the ileum.

Gastrointestinal motility consists of phasic slow-wave contractions and the migrating motor complex (MMC). Eupatilin (Stillen<sup>Ⓡ</sup>) has been widely used to treat gastritis and peptic ulcers, and various cytokines and neuropeptides are thought to be involved, which can affect gastrointestinal motility. We performed a study to identify the effects of eupatilin on lower gastrointestinal motility with electromechanical recordings of smooth muscles in the human ileum and colon. Ileum and colon samples were obtained from patients undergoing bowel resection. The tissues were immediately stored in oxygenated Krebs-Ringer s bicarbonate solution, and conventional microelectrode recordings from muscle cells and tension recordings from muscle strips and ileal or colonic segments were performed. Eupatilin was perfused into the tissue chamber, and changes in membrane potentials and contractions were measured. Hyperpolarization of resting membrane potential (RMP) was observed after administration of eupatilin. The amplitude, AUC, and frequency of tension recordings from circular and longitudinal smooth muscle strips and bowel segments of the ileum and colon were significantly decreased after admission of eupatilin. Eupatilin elicited dose-dependent decreases during segmental tension recordings. In conclusion, eupatilin (Stillen<sup>Ⓡ</sup>) showed inhibitory effects on the human ileum and colon. We propose that this drug may be useful for treating diseases that increase bowel motility, but further studies are necessary.

It is expected that the flexible display will provide various physical forms of the interface through its bendable, rollable or foldable characteristics without any damage and these forms are considered as the core factors to deliver user experiences in the interface. In this study, we determined the ways of utilization of the form factors in the design phase of the user experience by analyzing the effectiveness of the flexible display’s form factors to each and every user experience type through a survey. The analyzed user experiences are Functionality, Understandability, Pleasure, Convenience, Familiarity, Stimulation, Adaptability, Collectivity, Reality, and Aesthetic; the results showed that each user experience type has a different level of effectiveness of the form factors. This indicated that particular user experiences and certain form factors are related and implies that the designer can use certain form factors to express particular user experiences.

Purpose: Rectovaginal fistula can result from various causes and diverse surgical procedures have developed as a result. We investigated the outcomes of surgical treatments for rectovaginal fistula according to causes and procedures. Methods: Between 1998 and 2016, 92 patients underwent 128 operations for rectovaginal fistula. Prospectively collected data were recorded, and a retrospective review was conducted. Results: The median age was 49 years, and low fistula occurred in 58 patients (63.0%). The most common cause was radiation therapy, followed by pelvic operation, birth injury, perineal operation, cancer invasion, and trauma. The most common procedure during the first operation was diverting ostomy alone, followed by transanal rectal advancement flap, sphincteroplasty with perineoplasty, bowel resection, fistulectomy with seton placement, and Martius flap. Thirtyone patients (33.7%) experienced successful closure after the first operation. Repeated operations were performed in 16 patients (17.4%), including gracilis muscle transpositions, stem cell injections, and Martius flaps. The overall success rate was 42.4% (n = 39). Radiation therapy and pelvic operation as cause of fistula were significantly poor prognostic factors (P = 0.010, P = 0.045) and Crohn disease had a tendency for poor prognostic factors (P = 0.058). Conclusion: Radiation therapy and pelvic operation for cancer were more common causes than birth injury, and these causes of rectovaginal fistula were the most important prognostic factors. An individualized approach and repeated surgeries with complex or newly developed procedures, even among high-risk causes of fistula, may be necessary to achieve successful closure.
