      • 합성곱 신경망 기반 미세한 책 소리 분류 및 활용

        김혜주(Hye-Ju Kim),김승찬(Seung-Chan Kim) 한국HCI학회 2020 한국HCI학회 학술대회 Vol.2020 No.2

        소비자들은 도서 구매를 할 때 여러 책을 훑어보면서 관심이 가는 책은 좀 더 꼼꼼히 살펴보는 행동을 하게 된다. 책에 대한 소비자의 관심 정도를 파악하는 방법은 대부분 설문조사를 통해서 이루어진다. 만약 주관적인 설문조사 방식이 아닌 소비자가 책을 어떠한 방식으로 읽고 있는지 정량적으로 파악할 수 있다면 어떤 책이 관심을 끌었는지 쉽게 파악할 수 있을 것이다. 이러한 맥락에서 본 논문에서는 책을 다룰 때 발생하는 미세한 소리에 근거하여 사용자가 책을 다루는 방법을 정량화하고자 한다. 본 연구에서는 예비 연구 (preliminary work)로서 합성곱 신경망 (Convolutional Neural Network)을 이용하여 사용자의 책을 읽는 동작을 미세한 소리에 근거하여 분류 및 예측하는 방법을 제안한다. 타당성 검토를 위해 본 연구에서는 발생된 소리의 시간-주파수 특성을 분석하고자 스펙트로그램으로 표현하고, 이를 합성곱 신경망을 이용하여 학습해 사전 정의된 동작을 예측해냈다. 실험을 통해 책을 통한 8 가지 동작에 대한 분석을 시도하여 소리만으로 사용자의 동작을 정교하게 예측해 냄을 확인하였다.

        단전호흡 수련 전 , 후 혈장내 질소화합물의 생화학적 변화

        김갑수(Kab Soo Kim),조석주(Jo Suk Ju) 한국사회체육학회 2001 한국사회체육학회지 Vol.16 No.-

        The purpose of this study is to comparatively analyze the biochemical changes of the in-plasma non-nitrogen compounds between before and after the dahnjeon respiration training and thereby, determine the value of the dahnjeon respiration as aerobic exercise and its physiological effects. The results of this study can be summarized as follows; First, as a result of comparing the in-plasma glucose concentration between before and after the program, it was found that the concentrations were 121.38±10.06 mg/dl and 119.25±9.75 mg/dl, respectively, which was insignificant statistically. Nevertheless, the glucose concentration was lowered by the training program, although insignificantly. Second, as a result of comparing the triglyceride concentration between before and after the program, it was found that the concentrations were 154.63±7.61 mg/dl and 153.25±8.03 mg/dl, respectively, which was significant statistically. Third, as a consequence of comparing the total cholesterol concentration between before and after the training program, it was found that the concentrations were 197.00±11.75 mg/dl and 193.63±11.25 mg/dl, respectively, which was also significant statistically. Fourth, as a result of comparing the HDL-C concentration between before and after the program, it was found that the concentrations were 53.25±7.09 mg/dl and 54.50±6.95 mg/dl, respectively, which was significant statistically, too. Fifth, as a result of comparing the LDL-C concentration between before and after the training program, it was found that the concentrations were 117.50±6.93 mg/dl and 115.50±6.82 mg/dl, respectively, which was also significant statistically. In conclusion, it was found through this study that after the dahnjeon respiration training, the in-body non-nitrogen compound concentrations has conspicuously lowered, which seemed to be very desirable to health. All these findings suggests that although the dahnjeon respiration training seems to be very static, it has an aerobic exercise effect. All in all, the dahnjeon respiration training which seems to be at once static and dynamic may be a good sports recommendable for the aging people.

        급성위장관염 환자에서 검출된 노로 바이러스 Genogroup-I과 Genogroup-II의 분자생물학적 특성

        함희진,오세아,김창규,장정임,조석주,최성민,Ham, Hee-Jin,Oh, Se-Ah,Kim, Chang-Kyu,Jang, Jung-Im,Jo, Suk-Ju,Choi, Sung-Min 한국환경보건학회 2012 한국환경보건학회지 Vol.38 No.1

        Objectives: For our survey of the incidence of norovirus infections and the genogroup distribution of norovirus in Seoul, Republic of Korea, we evaluated through regular surveillance the prevalence of norovirus infections in patients with acute gastroenteritis occurring in Seoul from January 2007 to July 2011. Methods: For norovirus detection, we conducted epidemiological analyses on the basis of the junction of ORF1 and ORF2 (approximately 314 bp). 11,202 fecal specimens were collected from patients in Seoul with acute gastroenteritis between January 2007 and July 2011 and then tested for the presence of NoV via reverse transcription (RT) - polymerase chain reaction (PCR). Results: 16.6% (1,861/11,202) of the fecal specimens were determined to be positive for noroviruses. The incidences of norovirus infection in Seoul in the case of acute gastroenteritis with regular surveillance were 28.0% in 2007, 14.6% in 2008, 9.1% in 2009, 14.1% in 2010, and 12.9% in 2011, which shows that noroviruses constituted a major causative agent of acute gastroenteritis. Also, the incidence of noroviral infection in patients with acute gastroenteritis increased after the large-scale new influenza in 2009. Conclusions: The genetic characteristics of norovirus and the epidemiologic patterns of a viral pathogen in acute gastroenteritis patients may provide potentially effective data for epidemiological studies in Seoul, Korea.

        부산지역 의과대학생을 대상으로 한 응급처치 및 심폐소생술 교육 경험

        Purpose: The aim of this study was to describe the experience of teaching emergency management and cardiopulmonary resuscitation to medical students in Busan. Methods: Study participants were 59 medical students in Busan. An eight-day curriculum in the emergency management and cardiopulmonary resuscitation was developed. They completed all class sessions and two drill/practical examinations taught by our interdisciplinary team from July 21 through 30, 2003. Each class is approximately 2 hours and reading assignments are given at the end of each class. Also included are practical, table-top and team-building exercises. The participants completed self-reported questionnaires for the education. Results: About establishment and environment of the education, respondents answered with `very good were 14%. About overall theoretical lecture, respondents answered with `very helpful were lower than 40%. Especially, favorable evaluation for the medical lectures was lower than that of other lectures. Students generally enjoyed their emergency medicine experience as it is often their first opportunity to assume primary responsibility for patient care. About overall practices, respondents answered with very helpful were higher than 60%. Conclusion: The authors found that medical students prefer opportunities to hone procedural skills than to hear theoretical lectures. Also, medical students are welcome to hear theoretical lectures that consists of emergency management related contents, not academically medical contents. This curriculum should be tailored to fulfill learner s requirements.
