This study aimed to investigate oral health disparities in older adults according to household income and residential area. Data was obtained from the seventh Korean National Health and Nutrition Examination Survey (KNHANES). The final sample consisted of 3,405 older adults aged 65 years or older. Oral health disparities were assessed in terms of the average number of teeth, having 20 teeth or more, and edentulism. Main findings are as follows. First, oral health disparities by income level were confirmed. Older adults belong to 5th quintile income group had 5 more teeth on average compared to 1st quintile income group and had higher odds to have 20 or more teeth that are needed for normal chewing ability. Second, oral health disparities by residential area were also confirmed. Older adults living in the metropolitan areas had higher number of teeth on average and had lower odds to have less than 20 teeth or become edentulism compared to older adults in mid-size city or rural area. Follow-up studies focusing community factors associated with oral health and community-based programs to improve dental care access for vulnerable groups were suggested. 본 연구의 목적은 소득수준과 거주지역에 따른 노인의 구강건강 격차를 분석하는 것이다. 제7기 국민건강영양조사(Korean National Health and Nutrition Examination Survey) 자료에 포함된 65세 이상 노인 3,405명의 자료를 이용하여 자연치아 보유 개수, 20개 이상 치아보유 여부, 무치악과 관련된 현황을 분석하고 가구소득과 지역거주에 따른 차이를 검증하였다. 연구결과는 다음과 같다. 첫째, 소득수준에 따른 구강건강 격차를 확인하였다. 고소득층인 5분위 노인은 1분위 노인에 비하여 평균 치아 수가 5개 많았으며, 정상적인 저작기능을 위하여 필요한 20개 이상의 치아를 보유할 가능성이 현저히 높은 것으로 나타났다. 둘째, 거주지역에 따른 구강건강 격차를 확인하였다. 대도시 거주 노인은 중소도시 혹은 농어촌 지역 노인과 비교할 때 평균 치아 수가 많았으며 치아상실을 경험할 가능성은 낮은 것으로 나타났다. 이상의 결과를 바탕으로 구강건강과 관련한 지역사회 요인의 영향을 분석하는 후속연구를 제시하였고, 취약계층의 치과서비스 접근성을 향상시킬 지역사회 프로그램을 제안하였다.

Objectives: This study aimed to investigate the factors associated with unmet dental needs among adults with activity limitations. Methods: Data were obtained from the seventh Korean National Health and Nutrition Examination Survey (KNHANES). The final sample consisted of 945 adults aged 20 years or older with limited activity. Logistic regression analysis was used to examine the influence of predisposing, enabling, and need factors on unmet dental needs. Results: The proportion of adults with unmet dental needs during the last year was 52.2% in the middle-aged group and 45.5% in the older adult group. Higher household income was associated with fewer unmet dental needs in both groups. In the older adult group, married people were less likely to have unmet dental needs. In the middle-aged group, adults who perceived their oral health as poor were more likely to have unmet dental needs. Conclusions: All three factors (predisposing, enabling, and need) were found to be associated with unmet dental needs among adults with activity limitations. Special efforts should be made to improve access to dental care services for middle-aged adults with activity limitations.

As of the 2021 survey, the domestic coffee market is approximately $4.3 billion in size, which makes it the third largest in the world. The domestic coffee market has matured, and it is presently divided into price and quality competition. The purpose of this study is to determine if high-end coffee can be defined by establishing standards that can categorize the highest quality coffee within different grades of specialty coffee. Additionally, it aims to assess whether the introduction of high-end coffee is necessary in the domestic market. The research method applied the Delphi method on a group of coffee experts, and the results were derived using systematic inference, qualitative analysis, and SWOT analysis methods. The research results confirmed the positive perception of defining high-end coffee by the group of coffee experts. Additionally, it was confirmed that there was a perception that the introduction of high-end coffee was necessary. The domestic high-quality coffee market has been divided into specialty coffee and high-end coffee, and it has been confirmed that they share a complementary relationship rather than a competitive one. The limitation of this study is that it is focused on a small group of only eight coffee experts, thus its results may not be broadly applicable. In future studies, there is a need to expand quantitative research and conduct detailed studies on consumer awareness and acceptance of high-end coffee.

This study investigated the epidemiological characteristics of adult patients diagnosed with attention deficit hyperactivity disorder in mental health outpatient clinic from 2012. Through the collection and analysis the data of 189 outpatients initially diagnosed with adult ADHD by DSM-IV criteria, sociodemographic data, and diagnostic data (school record, ASRS:Adult ADHD Self-Report Scale, CPT: Continuous Performance Test, Emotional dysregulation scale, BAI:Beck Anxiety Inventory, BDI:Beck Depression Inventory, self esteem scale) since January 1, 2012, we confirmed the sociodemographic characteristics of patients diagnosed with adult ADHD, and identified the changes in the demographic characteristics by comparing the previous epidemiological study (Journal of Society of Korean Women Psychiatrists, Volume 11, No. 1, 2013). The results showed that the first diagnosed with ADHD in adulthood age was 29.8 year and the first diagnosed with ADHD in adulthood age of 183 participants except for 6 diagnosed ADHD prior to adulthood was 29.97 year, therefore the age of first diagnosed with ADHD in adulthood was slower than the 27.5 years of previous research and showed the delay compared to 28.1 years of age, except for people who were diagnosed prior to adulthood. However, there was no significant difference in first diagnosed age between the two studies. In the age groups, there was significantly increased the 30 age group, and the education level also significantly increased over University Student group. In this study, there was significantly high proportion of married status. The proportion of main complaining with ADHD-related problem was 33.3% (n=63), it showed significantly elevated compared to 13.3% in the previous study. In accordance with ADHD subtype, Inattentive type was 36.8%, Combined type and Hyperactive/Impulsive type was 61.4%, it showed that the proportion of Combined type significantly elevated compared with previous study. However, the history of ADHD diagnosis in the study group was significantly lower than in previous research group. Through this research, especially, the raising of public perception about adult ADHD was judged by the significant elevation of the proportion of main complaining with ADHD-related problem at first psychiatric clinic visit. Since the extension of national insurance to cover adult ADHD patients began from September 1, 2016, we will compare the future changes in the epidemiological characteristics through further research. In addition, because it is possible to apply the DSM-5 criteria much more relaxed than rigid DSM-IV criteria, the more changes in the epidemiological characteristics will be expected. Through this, it will be able to compare the epidemiological characteristics of adult ADHD patients in the present and future policy changes, and we expect to provide the future direction of health policy and practice.

A single coronary artery is a rare coronary anomaly. A 66-year-old man arrived at our emergency department with progressive dyspnea of 4 days duration. ST segment elevation,a Q wave in precordial leads, and elevated myocardial enzymes suggested recent myocardial necrosis. Coronary angiography revealed a single coronary artery that originated from the left coronary sinus and showed normal morphology of the left coronary system without a significant stenotic lesion;a distal left circumflex artery traveled to the right ventricle and right atrium as a functional right coronary artery. We report a case of a single coronary artery from a left coronary sinus with a brief review of the literature.

This research conducted a preliminary study of 23 adult attention deficit hyperactivity disorder patients who visited psychiatric outpatient department. The research contains their responses after six-month treatment of methylphenidate Osmotic-controlled Release Oral delivery System (OROS), and the correlation among the adult attention deficit hyperactivity disorder subtypes. Both before and after the six-month treatment, we conducted continuous performance test (CPT) test on the subject group to estimate the alternation of their attention. As a result, the general improvement of attention was reported. Also, regarding the high correlation between the Eysenck's personality trait and the subtypes, the necessity of additional research on a large number of patients was suggested.

Acoustic scene classification (ASC) categorizes an audio file based on the environment in which it has been recorded. This has long been studied in the detection and classification of acoustic scenes and events (DCASE). In this study, we considered the problem that ASC faces in real-world applications that the model used should have low-complexity. We compared several models that apply light-weight techniques. First, a base CNN model was proposed using log mel-spectrogram, deltas, and delta-deltas features. Second, depthwise separable convolution, linear bottleneck inverted residual block was applied to the convolutional layer, and Quantization was applied to the models to develop a low-complexity model. The model considering low-complexity was similar or slightly inferior to the performance of the base model, but the model size was significantly reduced from 503 KB to 42.76 KB. 음향 장면 분류는 오디오 파일이 녹음된 환경이 어디인지 분류하는 문제이다. 이는 음향 장면 분류와 관련한 대회인 DCASE 대회에서 꾸준하게 연구되었던 분야이다. 실제 응용 분야에 음향 장면 분류 문제를 적용할 때, 모델의 복잡도를 고려하여야 한다. 특히 경량 기기에 적용하기 위해서는 경량 딥러닝 모델이 필요하다. 우리는 경량 기술이 적용된 여러 모델을 비교하였다. 먼저 log mel-spectrogram, deltas, delta-deltas 피쳐를 사용한 합성곱 신경망(CNN) 기반의 기본 모델을 제안하였다. 그리고 원래의 합성곱 층을 depthwise separable convolution block, linear bottleneck inverted residual block과 같은 효율적인 합성곱 블록으로 대체하고, 각 모델에 대하여 Quantization를 적용하여 경량 모델을 제안하였다. 경량화 기술을 고려한 모델은 기본 모델에 대비하여 성능이 비슷하거나 조금 낮은 성능을 보였지만, 모델 사이즈는 503KB에서 42.76KB로 작아진 것을 확인하였다.
