There is a need to develop a data quality management algorithm in order to improve the quality of health care data. In this study, we developed a data quality control algorithms associated diseases related to diabetes in patients with hypertension. To make a data quality algorithm, we extracted hypertension patients from 2011 and 2012 discharge damage survey data. As the result of developing Data quality management algorithm, significant factors in hypertension patients with diabetes are gender, age, Glomerular disorders in diabetes mellitus, Diabetic retinopathy, Diabetic polyneuropathy, Closed [percutaneous] [needle] biopsy of kidney. Depending on the decision tree results, we defined Outlier which was probability values associated with a patient having diabetes corporal with hypertension or more than 80%, or not more than 20%, and found six groups with extreme values for diabetes accompanying hypertension patients. Thus there is a need to check the actual data contained in the Outlier(extreme value) groups to improve the quality of the data.
Reflecting the reality that 70% of Korea's population lives in apartment, many studies have been conducted on CPTED's perspective on crime in apartment, but crime and CPTED studies in public rental housing are very insufficient and CPTED certification is mainly applied to private construction apartment. Therefore, this study analyzes the perception and physical status of crime safety of residents of public rental housing and private apartments certified by the Korean Cpted Association, and seeks ways to prevent crime and reduce fear in public rental housing in the future. The study focused on field and drawing analysis (number of households, type and layout, outdoor space composition and facilities), questionnaire analysis(socio-demographic factors, psycho-behavioral factors, fear of crime factors, recognition of crime prevention environment, etc.), and crime analysis (5 major crimes). To summarize the research results, in the case of the physical environment, the mainstay of private apartments is the cascade structure, and the complex consists of various outdoor spaces and community facilities. On the other hand, the main building of public rental housing was a corridor-type structure, and the degree of facilities was somewhat insufficient compared to the size of the outdoor space, and there was a difference between underground parking lots and community facilities. From a socio-demographic point of view, public rental housing were the most inhabited by single-person households in their 20s, which was found to have high demand for housing for young single-person households due to the concentration of public institutions relocated to base national universities and innovative cities. From a psycho-behavioral point of view, public rental housing were most frequently selected as reasons for low life satisfaction, including unsafe environments from crime and apartment design, which is believed to reflect the fundamental problems of public housing. From the perspective of crime safety, private apartments had high satisfaction with the visibility and number of installations such as surveillance cameras and emergency bells, but public rental housing had low satisfaction or negative perceptions. In the comparison of overall crime awareness and fear of crime by type, apartment residents who received CPTED certification had high satisfaction and low fear. The high response that it will contribute to the expected effect of reducing fear of crime and the improvement of apartment brand value is believed to provide implications for the expansion of CPTED certification in the future. This study was conducted based on the survey, and it is factors by identifying the differences in resident perception by item and confirming the positive effect on CPTED. However, since statistical analysis according to variable factors is insufficient, subsequent studies will need to supplement this.
It is most effective to apply CPTED in the architectural design stage. On the other hand, the use of BIM is increasing in the construction field. BIM is used for information linkage and performance analysis simulation by building life-cycle. In particular, BIM-based legality review can be conducted at Construction Consult. In line with these changes in the architectural field, it is necessary to conduct research to use BIM in the CPTED field. It will be possible to supplement various limitations that have appeared in the application of CPTED for each building life-cycle stage. Therefore, in this study, the legal system for applying BIM and CPTED in the Construction Consent stage is considered. Next, this study examines BIM-related studies that appeared in 1) the architectural design stage, 2) the architectural construction consultation stage, and 3) the CPTED design certification stage. The purpose of this is to derive future research directions.
Experimental research is a method suitable for intentionally creating the environment desired by the researcher and revealing the causal relationship between variables. The characteristics of these experimental studies are being utilized in the CPTED field to overcome the survey's limitations. However, there are few cases of experimental research conducted in domestic CPTED experimental research compared to other fields. And most of the simple experimental designs(pre-experimental design) are performed, so the design is insufficient. In addition, some studies have limitations that are difficult for subsequent researchers to apply because the experimental design and process do not appear in detail. Therefore, this study recognized the necessity of an effective experimental research system, and the concept of experimental research and the experimental design of previous studies were considered. Finally, the experimental design of the previous study was supplemented through the analysis results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
