The purpose of this study is to establish a crime prevention system through the Crime Prevention Through Environmental Design (CPTED). The research method went through the double diamond process and discovered the user's needs through the persona analysis. The most representative features are the functions that informs users of the safe and optimal route, checks the presence of streetlights or cctvs in real time to update them, and allows people with similar routs to return home together. It is a function to help safe return home with the help of an autonomous method, and a self-defense function to protect themselves. Therefore, the application presented in this study was intended to be of great help when actually returning home by adding these new functions. In particular, we help users to return home most safely by recommending the best safe route. Through the persona analysis, research method which we had chosen, the needs of users were discovered and implemented in a design that reflected those needs and requirements.

The safe return home system automatically tracks and makes a video-recording the client by selecting and controlling CCTV cameras near the client using GPS location information received from the smart device possessed by the service client. This service helps clients to return home safely when there is a crime-ridden district on their late night return home route. If the CCTV cameras that can capture the client are already occupied and used by other clients, concession of occupied CCTV cameras is required to capture the new client. To tackle the limitation, we developed an extended method that considered both the average distances between the client and CCTV cameras and the service rates. As a result, the average distance between CCTV cameras and clients is kept close, and service rates are improved.

When user wants to receive a smart safe return service, user sends a service request using a smart device to support GPS location data. After the smart safe return system receives the location of user, it selects the neighboring CCTV cameras based on user's location information, and controls the selected CCTV cameras to take a picture of the user, and to chase the user automatically. This service can be useful when there is a crime-ridden district on the path to return home late at night. Previous systems can't provide the smart safe return service to multiple user simultaneously. In this paper, we propose the smart safe return system which can provide the service to multiple users simultaneously.

Background: Promoting patients' safe return home at discharge and reducing length of stay in hospital is key for Restorative Rehabilitation Institution (RMI). Objects: This study was designed to identify the factors influencing the return to home and length of stay among various factors. Methods: A total of 120 stroke patients (76 males and 44 females) who were hospitalized in an adult inpatient unit of a RMI for more than 2 months were retrospectively analyzed for this study (multivariate logistic regression analyses, p < 0.001). As predictor variables for assessing the return to home and length of stay, demographic data (sex, age, duration between onset and admission, length of stay, caregiver after discharge, occupation after discharge, reason for discharge, and household type after discharge) were collected. Additionally, following measurements were selectively collected from patient's medical records: scores of Mini-Mental State Examination Korean version (K-MMSE), modified Barthel Index Korean version (K-MBI), Berg Balance Scale and Functional Ambulation Category were obtained at admission and discharge. Results: The K-MMSE at admission and K-MBI at discharge were found to be the predictors of return to home. Additionally, K-MBI at admission influenced the length of stay. Conclusion: This study suggests cognitive functioning at admission and the level of activities of daily living at discharge predicted the return to home and length of stay.

현재 안심 귀가 서비스는 주로 여성, 자녀, 택시를 대상으로 하지만 단체를 위한 귀가 서비스는 존재하지 않는다. 현재 서비스되고 있는 안심 귀가 어플들은 1:1이며 이 경우 인원수만큼 연락을 해야 하는 문제가 있다. 본 논문에서는 이동하기 전 그룹을 설정하여 사람들의 귀가 여부, 집까지 소요시간, 이동 수단 정보를 알 수 있고 목적지에 도착하지 않았을 때 그룹원들에게 알림을 줌으로써 범죄의 가능성을 줄이고 안전하게 귀가하는 서비스를 제안하고자 한다.

Purpose: This study was conducted to compare three discharge criteria; 1) discharge criteria of S Hospital determined by nurses, 2) discharge readiness determined by patients, and 3) the Modified Post-Anesthetic Discharge Scoring System (MPADSS). The usefulness of MPADSS as a discharge criteria for the patients'safe return to home after ambulatory surgery was also evaluated. Methods: A total of 370 day surgery cases were investigated. The MPADSS was employed in every 30 min. in parallel with discharge readiness assessment by nurses and patients. The percentage of the patients who were categorized as being ready to discharge were compared according to three discharge criteria. Results: The percentage of patients scored to be as MPADSS > 9 in 30 min, 60 min, 90 min were 96.5%, 99.5%, 100%respectively. Whereas 11.1%, 44.3%, 71.1%of patients rated themselves as being ready to discharge and 2.7%, 23.5%, 54.3% of patients actually discharged by nurses according to discharge criteria of S Hospital. Conclusion: Nurses tend to keep patients longer in the hospital when compared to the patient's own assessment about their readiness to home and to that of MPADSS. Faster discharge in the evening than day time suggests patient discharge can be influenced by nursing factors. This brings out the importance of scoring system to determine the safe discharge. The MPADSS could be a useful tool in evaluating patients for safe discharge.

Recently, interest in living safety and crime prevention is increasing. The reality is that most women have anxiety about social safety and ultimately want a safe return to home. As a result of these issues, the Seoul Metropolitan Government and the National Police Agency are implementing various services to alleviate them. However, there are limitations such as that the service can be used only during a limited time or the process of checking whether the patrol is really completed is complicated. Therefore, in this paper, we propose a service platform that overcomes these limitations and suggests the best and shortest patrol route to the police based on the desired patrol location applied by citizens. It is designed based on the MVC pattern, and the functions are divided for each user. It is hoped that the platform will reduce crime rates and allow citizens to ultimately return home with peace of mind. Also we expect that the police will ablet to find places where they did not know about or need to patrol with more attention through the recommended route of the platform, which will be helpful in their task.

최근 학교폭력 및 묻지마 범죄가 꾸준히 증가추세에 있다. 2011년 12월 학교폭력에 의한 대구중학생 자살사건, 2010년 2월 김길태 사건과 6월 김수철 사건, 2016년 5월 강남역 노래방 살인사건과 6월 섬마을 여교사 사건 등 사회적 약자인 소년, 여성 대상범죄 및 묻지마 범죄가 사회문제로 대두되고 있다. 이에 따라 범죄예방 도구이자 전략으로써 CPTED가 하나의 대안으로 부각되고 있다. 국토교통부는 건축물, 건축설비 및 대지에 관한 범죄예방 기준인 '범죄예방 건축기준 고시'를 2015년부터 시행하고 있는데 적용대상 건물 등은 이 기준에 따라 설계하고 건축해야 한다. 현대 위험사회에서 강력범죄 및 경범죄의 사전예방을 위해서는 사회 안전시스템 구축이 요구되며 그 대안으로 환경설계를 통해 범행기회를 심리적, 물리적으로 차단하는 정책을 모색함으로써 환경범죄학 입장에서 범죄예방에 접근할 필요가 있다.

This study has focused on the transfer of infants and Toddlers-protecting responsibilities from families to infants and Toddlers education agencies due to an increase of a double-income family and nuclear family. It is because there is insufficient safe play space from the moment when infants and Toddlers return from infants and Toddlers education agencies to home due to a high crowding of housing and increase of vehicle, and there can be difficulties to take responsibilities of infants and Toddlers safety with a mere recognition and effort of parent. Thus, to suggest a safety education through mutual contact between the communities and agencies supporting parent role in a level of social welfare, its potential has been identified through a frequency analysis on 60 participants of experimental group who have trained a safety education and 60 participants of control group who have not trained a safety education. As a result of frequency analysis, the increase in safety condition in Korea, safety and development of infants and Toddlers, safety of play materials, and safety knowledge on general part of facility safety has detected and the practice of safety and safety consciousness has also identified to be more effective. The results of this study has shown a potential to verify its efficacy if it is verified through an elaborative model of safety education based on parents of young infants and Toddlers family.
