Purpose: The purpose of this study was to determine the effect of preoperative guidance and operating room environment experience using virtual reality on increasing satisfaction with information and reducing anxiety in preoperative patients undergoing general anesthesia and local anesthesia. Methods: A non-equivalent control group quasi-experimental design was employed. The participants were 80 surgical patients from 4 wards (40 experimental group and 40 control group) of the general hospital located in Gyeonggi-do. Data collection was conducted from June to November 2023 after completing the control group survey in January 2023. Data were analyzed using Chi-square, t-test, and Mann-Whitney U test using SPSS 23.0 program. Results: Satisfaction with preoperative information was higher in the experimental group than that of the control group. Additionally, anxiety related to surgery in the experimental group was significantly lower than that of the control group. The preoperative state anxiety score in the experimental group was not significantly lower than that of the control group. Conclusions: These results suggest that providing patient education and information using virtual reality technology can not only alleviate patients' anxiety related to surgery, but also have the potential to be used as an effective intervention to improve positive patient experiences.

협업과 소통하는 업무 분위기가 중시되면서 개방형 사무실이나 공유사무실이 나타나고 있다. 기존에는 사용자가 공간 유지보수의 주체가 되었으나 정해진 자리가 없어지면서 실내공간의 유지관리가 어렵게 되었다. ICBM 프레임워크를 활용한다면 실내 공간에 대한 정보를 수집하고, 공간유지보수에 활용 할 수 있을 것이다. 따라서, 본 연구에서는 ICBM(Internet of Things, Cloud, Big Data, Mobile) 기반의 프레임워크를 제안하고 이를 활용한 실내공간 유지관리 시스템의 가능성을 검토 하였다. IoT(Internet of Things, 사물인터넷)기술을 이용하여 실내의 온도, 상대습도, 재실 여부, 밝기를 지속적으로 측정하고 WiFi를 통해 Web API 에 제공한다. 온습도센서, 조도센서, 초음파 거리센서와 와이파이 모듈로 구성된 IoT 디바이스를 설계하고 프로토타입을 제작하였다. IoT를 통해 자동으로 취득된 데이터와 기존 유지보수 데이터, 공간정보가 Cloud(클라우드)를 통해 통합된다. 센서로 수집한 Big Data(빅데이터)는 유지보수용으로 의미 있는 공간 정보로 가공할 수 있을 것이다. 실내 공간 정보 및 유지관리 사항을 모바일(Mobile)을 통해 관리자에게 전달할 수 있다. 데이터 수집결과, 사용된 초음파센서의 측정범위 한계로 인해 재실여부의 파악은 제한적이었다. 하지만 밝기 정보는 공간의 활용 행태를 충분히 나타내어, 조명의 켜짐/꺼짐여부와 주말, 주중의 차이를 확인할 수 있었다. 온도와 상대습도 정보 또한 안정적으로 수집되어 공간의 쾌적성을 평가할 수 있었다.

Purpose: This study was done to describe utilization status of emergency medical service for children at one university affiliated hospital located in Seoul. Data were obtained from the medical records of patients under 13 years of age who visited the ER from January 1 to December 31, 2006. Method: Medical records missing the time of discharge were excluded in the analysis of waiting time, which resulted in 19,766 cases. Data were analyzed using SPSS WIN 14.0 version. Result: There were slightly more boys (58.4%), average age of the children was 3.97 years of age. More children at the aged 1 to 3 years (51.3%) visited the ER. Fever was the most frequent complaint: 5,180 cases (24.38%). The other complaints were head or facial laceration (10.55%), vomiting (9.63%), abdominal pain (8.06%), cough (7.67%), and painful limb swelling (6.34%). Average waiting time before the first medical examination was 17 minutes, and average ER stay time was 3 hours and 23 minutes. Conclusion: The results suggest the need to assign a nurse specialist for pediatric ER to provide more efficient care for the children. Also, extra staff assignment during the evening shift or extending office hours of local pediatricians should be considered.

According to the Korean National Statistics Office(KNSO), more than 90% of Korean adolescents aged from 15 to 19 use a computer for more than 10 hours per week. The KNSO also reveals that this age group mostly uses a computer in their own room, followed by a commercial place. It is also found that the house for the adolescent is not simply a physical environment, but is rather a center of their personal lives where their personal and social developments are formed. Therefore, the physical environment where computers are used is very important. The purpose of this study was to investigate the characteristics and needs of computer furniture for the adolescent. Data were collected through self-administered questionnaires and 414 adolescents participated. The results of this study are as follows: (1) Most of the respondents(42%) used the internet for less than one hour per day and it was used for community visits and operations, game, and chat rooms. (2) The desks where computers were used were specially designed and made of wood. Chairs were typically height adjustable with armrests and there was no task lighting for computer use. (3) The preferences of computer furniture were chairs with a high back, casters and armrests. The overall satisfaction of individual computer rooms was low. However, it is important for an adolescent to be provided with a user friendly environment for sound growth and development. Further study is therefore needed regarding environmental variables through empirical study.

청소로봇이나 경비로봇과 같이 실내에서 이동하며 작업하는 로봇에서는 센서를 통한 환경의 인식이 필수적이다. 사무실 빌딩이나 공동주택의 경우 기본적인 환경이 동일하므로 설계도와 같은 공통된 지도를 이용하면 개별 환경마다 지도를 재작성하는 것보다 유리한 점이 있다. 이때 가구나 장애물 등 위치가 바뀔 수 있는 대상의 정보는 제거하고, 벽, 문, 창 등 불변의 대상을 인식하는 것이 중요하다. 이 논문에서는 사무실이나 가정환경에서 사용할 수 있는 실험용 이동로봇을 구현하고, 레이저스캐너의 정보와 세그먼트의 방향, 위치에 의한 히스토그램 방법을 이용하여 이와 같은 불변의 특징을 추출한다. 로봇에는 레이저스캐너, 자이로 센서, 초음파 센서, 적외선 센서 등이 탑재되며 제어프로그램은 C 프로그램으로 작성되었다.

The purpose of this study was to identify school dieticians' perceptions on the Potentially Hazardous Food (PHF) and the inspection of food safety and sanitation conducted by Provincial Office of Education. Questionnaires were distributed to 400 school dieticians in elementary schools in Seoul and Gyeonggi Province, and 217 responses were collected. The majority of respondents (64%) defined PHF as food that easily decays at room temperature and over half of the respondents considered Korean cooked vegetables as a PHF. In addition, 4% of respondents completely excluded PHFs from their menus. Forty five percent of the respondents selected CCP rule 7 (delivery and distribution process) and 34% selected CCP rule 6 as the most difficult of the CCP rules to follow. Also, perceptions concerning food safety inspection and sanitation were not high in terms of validity, objectivity, and reliability among the evaluation criteria. The study results suggest that PHF as well as Potentially Hazardous Menu (PHM) definitions and guidelines should be re-established in consideration of traditional Korean food culture and the preparation of Korean foods.

The purpose of this study is to investigate and analyze the actual conditions of consumer damage occuring in the use of clothing products. The data used for analysis included 470 cases, which were deliberated by requesting consumer disputes deliberation at the consumer consultation room of Masan YWCA at the Kyeongsangnamdo Consumer Life Center belonging to the Kyeongnam provincial office. The disputes regarding the clothing products insisted that consumers suffered damage for the period from March, 2011 to June, 2013. The data processing was carried out by SPSS 14 and the statistics techniques used went through a cross tabulation analysis and ${\chi}^2$-test. The results are as follows. The difference in the analysis result of purchase path and material as to kinds of clothing products showed a significant difference. The damage types of clothing products were classified into five types: change of color, change of style, change of surface and touch, breakage of subsidiary materials, and others. The damaged clothing products showed a difference for damage frequency according to the items of clothing products; in particular, damage frequency for change of color appeared high. The damage contents of change of color were identified as metachromatism, discoloration and yellowing, stain occurrence, and decolorization. The damage responsibility for these clothing products appeared to be various as to clothing items, but was higher at dry cleaners and manufacturers.

본 논문에서는 서로 다른 종류 또는 다수의 동일 가전기기를 그룹별로 관리할 수 있는 HBS(Home Bus System)을 분석하고, 기존의 독립된 제어시스템으로 중앙제어기를 구축하던 방식을 PC로 대체한 새로운 방식의 HBS 시스템을 설계하였다. 설계한 시스템은 빌딩에 설치된 에어컨을 통제실 또는 사무실에서 모니터링 및 제어할 수 있어 에너지를 효율적으로 관리할 수 있게 되었으며, 향후 유사 대규모 가전기기 통합 및 개별관리에 적용할 수 있어 홈오토메이션 구축에 크게 기여할 것으로 기대된다.
