모바일 디바이스의 발달은 사용자가 언제 어디서나 원하는 서비스에 접근하고, 정보를 소비할 수 있는 환경을 마련했다. 이에 맞춰 다양한 연구들이 모바일 사용자의 정보 접근성을 향상 시키기 위한 개인화 방법을 제안해 왔다. 하지만, 이와 같은 개인화는 사용자 개인과 관련된 정보를 요구하기에, 사용자 정보에 대한 보안과 관련된 우려를 낳고 있다. 이를 해결할 수 있는 효과적인 방법 중 하나로 사용자 정보를 사용자의 온라인 혹은 오프라인 상의 행동 패턴으로부터 추정하는 것을 들 수 있다. 본 논문에서는 SNS(Social Network Service) 상에서의 사용자 패턴과 사용자 간 물리적인 근접성 패턴을 분석하여 사용자 개인의 정보와 타 사용자와의 사회 관계정보를 식별하는 사용자 정보 식별 시스템을 제안하고자 한다. 제안한 시스템은 SNS 텍스트와 GPS 데이터에 기반한 POI(Point of Interest) 패턴으로부터 사용자의 나이, 성별 등 개인정보를 식별하고, 사용자 GPS 데이터를 이용하여 얻어진 사용자 간 근접성 패턴을 이용하여 두 사용자 간의 가족, 동료 등 관계 정보를 추정한다. 각각의 사용자 식별 모듈은 해당 데이터의 특성을 고려하여 SNS 데이터의 노이즈와 사용자 GPS 데이터의 손실을 감안함으로써 더 정확한 사용자 식별 성능을 보이도록 설계되었다. 이를 검증하기 위한 실험에서 제안한 시스템은 기존의 방법에 비해 더 나은 성능을 보였으며, 이는 본 논문에서 제안하는 방법이 사용자 데이터의 특성을 효과적으로 반영하고 있음을 의미한다.

1. Objectives As a basic trial for identification of Sasang constitutional gene marker, we genotyped and analysed statistical relationships of STR(short tandem repeat) alleles and its distribution in each constitution. 2. Methods After obtaining basic constitutional data with questionnaire (QSCC II), decision of constitution was made by 3 different constitution specialists' diagnosis, and only the samples of specialists' agreement of each constitution by discussion were taken into this research. Using multiplex PCR kit, total 146 constitutional samples were amplified in 16 autosomal STR marker, genotyped, and analysed statistically. Among 16 markers, 15 were analysed in this study excluding the amelogenin marker is used for in gender identification. 3. Results and Conclusions It is difficult to determine the relationship between constitution and STR marker as the sample size is small, however, Penta D and vWA were shown to be related statistically with constitution. It has been know that STRs has no genetic informations, however there are some recent research results showing STRs as a regulatory element, relationship between microsatellite instability and repeat number and size, and post-transcriptional sigualing. STRs which is not known about its function currently, are proposed to have function and/or regulatory activities anyhow with Sasang constitution. It is believed that the results of this study can halp determine and deatify the markers related to Sasang Constitutional Medicien.

Purpose: The purpose of this study was to investigate the effects of general, health, and alcohol-related characteristics on blood pressure and stress according to the Alcohol Use Disorders Identification Test (AUDIT). Methods: This was a descriptive study. From participants in the 2013 Korea National Health and Nutrition Examination Survey, 319 participants who responded to the survey when they were attending college or university were selected. Data were analyzed using the SPSS Win 23.0 program for composite sample data reflecting the composite design elements of stratification, colonization, and weighting. Results: Mean age of onset of alcohol drinking was $17.91{\pm}0.16$ years, the average AUDIT score was $7.56{\pm}0.41$, and 25 (9.1%) participants fell into the high-risk drinking group. In the high-risk AUDIT group, systolic blood pressure was influenced by age, gender, institution, health status, body mass index, and suicidal ideation, and the explanatory power of the model ($R^2$) was 75.0%. For diastolic blood pressure, institution and health status were the influential factors, and $R^2$ was 66.2%. Predictors of stress were health status, depression, and the age of onset of drinking, and $R^2$ was 57.2%. Conclusion: It was confirmed that the explanatory power of the variables in models of systolic and diastolic blood pressure and stress is greater in those with higher scores on AUDIT.

This paper describes effectiveness of accident reduction on vehicles equipped with AEB using accident data occurring in Korea. During the statistical period, we used the number of vehicles which are covered by auto insurance and the number of accidents. To maximize the reduction effect of accidents caused by the driver's carelessness, the analysis was limited to Physical Damage Coverage that covers the cost of repairing or replacing the damaged vehicle caused by the driver's fault. Due to Personal Information Protection Law, it was not capable of comparing the same vehicle using Vehicle Identification Number in this study. Instead of that, we used it as a similar vehicle, so there are limits to the comparison and analysis results. As a result of this study, we have found that the effect of reducing accidents was different depending on the vehicle class, but it was generally concluded that the number of accidents decreased when the vehicle was equipped with an AEB system. Domestic research on the AEB effect of reducing accidents is not active yet. Therefore, it is absolutely essential to analyze the effects according to various conditions such as driver's age, occupation and gender as well as expanding the study models in the future.

The discovery of biomarkers related to pattern identification (PI), the core diagnostic theory of Korean medicine (KM), is one of the methods that can provide objective and reliable evidence by applying PI to clinical practice. In this study, 40 diabetic patients and 41 healthy control subjects recruited from the Korean medicine clinic were examined to determine the human electrical response related to the deficiency pattern, a representative pattern of diabetes. Qi-Blood-Yin-Yang deficiency pattern scores, which are representative deficiency patterns for diabetes mellitus, were obtained through a questionnaire with verified reliability and validity, and the human electrical response was measured non-invasively using a bioimpedance meter. In ANCOVA analysis using gender as a covariate, the 5 kHz frequency resistance and 5-250 kHz frequency reactance were significantly lower in the diabetic group than in non-diabetic control group. In addition, the multiple regression analysis showed a positive correlation (R2=0.11~0.19) between the Yang deficiency pattern score and resistance value for the diabetic group; the correlation was higher at higher frequencies of 50kHz (R2=0.18) and 250kHz (R2=0.19) compared to 5kHz(R2=0.11). In contrast, there was no such significant association in the control group. It implies that bioimpedance resistance measured at finite frequencies may be useful in predicting Yang deficiency, which is closely related to diabetic complications by reflecting the decrease in body water content and metabolism. In the future, large-scale planned clinical studies will be needed to identify biomarkers associated with different types of PI in diabetes.
