길찾기 실험은 가상현실기법과 함께 다양하게 연구되어져 왔으며, 가상현실기법의 추이는 대중화와 상업화에 의해 비몰입형에서 몰입형으로 변화하고 있다. 이러한 측면에서 본 연구에서는 기존의 길찾기 실험연구에서 가상환경기법이 실제환경의 유사한 대체조건의 환경으로 활용된 것과는 달리 시지각의 차이가 존재함을 전제로 실제환경과 가상환경에 어떤 시지각 차이가 발생하는지를 확인하고자 하였다. 연구는 코엑스 스타필드의 전시홀로 향하는 경로 시작점을 선정하였으며, ETG와 VR실험은 각각 20명을 대상으로 길찾기 난이도로 분류하여 주어진 실험장소에서 ETG와 VR의 Attention Start Time(시선고정 시작 시간), High Attention Start Time(시각적 주의집중 시작 시간)의 시각정보를 확인하였다. 본 실험을 통하여 실제공간에서는 가상공간보다 길찾기를 위하여 시선집중의 시작 시간차이가 다르게 나타났으며, 시각적 주의집중을 하는 시간은 몰입된 가상공간에서 차이가 많은 것을 확인할 수가 있었다. 또한 시선고정의 시작은 새로운 시각적 자극이 많은 실제공간에서 차이를 많이 가지지만, 시각적 주의 집중으로 시각정보를 획득하는 것은 몰입된 가상공간에서 차이를 가져 가상공간에서의 정보획득이 실제공간보다 쉬움을 가정할 수 있었다. 가상현실기반 콘텐츠의 발전과 함께 가상환경의 정보를 어떻게 활용하는가가 중요한 시점에, 가상현실에서 실제와의 시지각 차이는 상호작용에서 경험의 차이를 발생시킬 수 있다. 따라서 본 연구는 추후 가상공간의 디자인 설계에서 가상공간에서 사용자의 시지각 정보의 이해도를 높이고 실제환경과 VR의 상호성을 극대화하기 위한 기초적인 자료로써 활용될 수 있다고 본다. Wayfinding experiments have been studied diversely along with virtual reality techniques, and the trend of virtual reality techniques is changing from non-immersive to immersive types due to popularization and commercialization. In this regard, unlike existing wayfinding experimental studies where virtual environment techniques were used as environments with similar alternate conditions for real environments, this study was conducted to identify what differences in visual perception occur between real environments and virtual environments based on the premise that there are differences in visual perception. In this study, starting points of paths to the exhibition hall of COEX Starfield were selected, and ETG and VR experiments were conducted with 20 experimental subjects each. The visual information at the attention start time and high attention start time of ETG and VR was identified at the experimental places given after being classified with difficulties in wayfinding. Through these experiments, it could be seen that the attention start time in real spaces was different from that in virtual spaces and that the time of high attention was longer in the immersed virtual spaces. In addition, although the start of attention was earlier in real spaces where there are many new visual stimuli, the acquisition of visual information with high attention was faster in virtual spaces so that it could be assumed that the acquisition of information in virtual spaces is easier than that in real spaces. With the development of virtual reality-based content, at this time when how to utilize information in virtual environments is important, the differences in visual perception between virtual reality and real environments can cause differences in experience in interactions. Therefore, it is believed that this study can be used as basic data to enhance users’ understanding of visual perception information in virtual spaces and maximize the reciprocity between real environments and VR in the design of the virtual spaces in the future.

공공 공간을 위한 서비스 시스템 디자인 전략 연구: 인천국제공항 입국 심사장을 중심으로

공공 공간은 물리적 환경의 특징과 장소의 이미지 측면에서 연구되던 기존의 연구 범위에서 확장하여, 최근 사용자 경험이 중요해지면서, 서비스 차원의 개념이 새롭게 부각되고 있다. 그러나 아직 서비스 디자인을 적용한 심도 있는 연구는 미흡한 실정이다. 본 연구는 공공 공간으로서 인천국제공항 입국 심사장으로 연구 범위를 제한하고, 향후 효과적인 서비스 시스템 디자인 전략과 방향성을 제안하고자 한다. 우선 인천국제공항의 진단에 앞서, 서비스 시스템 디자인의 개념 및 구성요소와 프로세스를 살펴보고, 해외 사례 분석을 통해 시사점을 도출하였다. 그리고 공항 이용객과 전문가 조사를 통해 핵심 가치를 도출하였으며, 이를 바탕으로 인천국제공항 입국 심사장을 위한 서비스 시스템 디자인 전략의 기본 콘셉트로 ``신속한 경험 2.0(Agility with Empathy)``을 도출하였다. 기본 콘셉트를 기준으로 서비스 디자인, 장소 브랜딩 디자인, 인테리어 디자인의 세 가지 차원으로 디자인 기본 지침을 제시하였다. 이는 향후 인천국제공항의 입국 심사장의 디자인 실행을 위한 기초연구 및 가이드라인으로서 활용될 수 있으며, 아직 연구가 미비한 서비스 시스템 디자인의 기초적 연구로서도 의의를 가질 것으로 기대된다. The public space is extended from the existing study range in the aspect of physical environmental feature and the image of place, the concept of service is being magnified as a new concept because the experience of recent user is becoming important. However, the in-depth study applied with service design is inadequate yet. This study was to limit the research range into the port of entry at Incheon International Airport as a public place and suggest effective strategies and directions of service system design in the future. Before the diagnosis of Incheon International Airport, we looked carefully into the concept, component and process of service system design and drew an implications through international case studies. The core value was drawn through the investigation from users and professionals. Based on it, the quickest experience 2.0 (Agility with Empathy) was drawn as a basic concept of service system design strategy for the port of entry. Based on the basic concept, we suggested design primers for three different level of service design, place blending design and interior design. It definitely can be used as a basic research and a guideline for making design for the port of entry at Incheon International Airport in the future and it is expected to have significance as a basic study of service system design which the study is still inadequate.

Purpose: Intense multidisciplinary team effort is required for the intestinal rehabilitation of patients afflicted with the short bowel syndrome (SBS). These include enteral and parenteral nutrition (PN) support, monitoring of complications related to treatment, and considering further medical or surgical options for intestinal adaptation. Methods: In the Intestinal Rehabilitation Team (IRT) at the Samsung Medical Center, we have experienced 20 cases of adult SBS requiring multidisciplinary intestinal rehabilitation. This study is a retrospective review of the collected medical records. Results: Of the 20 subjects treated, 12 patients were male and 8 patients were female. At the time of referral to the IRT, the mean age was 51.5 years, and the mean body weight was 50.1 kg, which was 90% of the usual body weight. The diseases or operative managements preceding massive bowel resection were malignancy in 11 cases, cardiac surgery in 2 cases, trauma in 2 cases and one case, each of tuberculosis, corrosive esophagitis, atrial fibrillation, simultaneous pancreas and kidney transplantation, and perforated appendicitis. Of these, there were 14 survivals and 6 mortalities. The fatalities were attributed to progression of disease, intestinal failure-associated liver disease, and sepsis (unrelated to intestinal failure) (2 cases each). Among the 14 surviving patients, 8 patients have been weaned off PN, whereas 6 are still dependent on PN (mean PN dependence 36%). Conclusion: This paper reports the results of multidisciplinary intestinal rehabilitation of adult short bowel patients treated at the Samsung Medical Center. Further studies are required to improve survival and enteral tolerance of these patients.

Purpose: Intestinal failure (IF) is a complex clinical condition requiring a multi-disciplinary team approach. Our objective was to set up the treatment protocols and education documents for IF patients for development of intestinal rehabilitation programs in our hospital. Methods: We compared the number of inpatients, length of hospital stay, mode of nutrition and calorie supply at discharge, and the frequency of blood transfusions before and after quality improvement of multidisciplinary activities, in order to evaluate the indirect effects of new protocols and training materials and for development of the intestinal rehabilitation system. Results: We integrated eleven protocols for treatment and monitoring and seven educational materials for patients and caregivers. We compared indirect effects before and after the quality improvement activities. The number of IF patients hospitalized was reduced from 12 to 9. The mean days of hospital stay was decreased from 322 days to 73 days, the average number of monthly blood transfusions was also reduced from 1.8 to 0.3. In addition, the percentage of patients administered enteral nutrition and calories supplied was increased at discharge. Conclusion: By integrating IF protocols and education materials for IF patients, we found possible indirect effects of intestinal rehabilitation using a multidisciplinary team approach.
