Background: The purpose of this research was to investigate the factors affecting the low back pain of workers in hospital. 214 subjects waking at two general hospitals in Yosu city participated in this survey. Subjects consisted of doctors, nurses, medical engineers, officers and general laborers. The survey data were collected by a written questionnaire which made out by themselves for 25 days, from fourth August to 29th August, 2008. Methods: The questionnaire consisted of four categories, general, occupational, working habitual and the daily living characteristics. The collected data were analyzed by Chi-square test based on the present or absent of low back pain. Results: 1. In the general characteristics, low back pain had no significant relationship to all factors, sex, ago, body mass index, weight and height. 2. In the occupational characteristics, the phase of distribution of low back pain had statistical significant differences in the working hours a week, satisfaction of pay, satisfaction of occupation(p<0.05). However low back pain did not significantly related to the kind of occupation, period of work and degree of stress. 3. In the habitual characteristics, low back pain was significantly influenced by working posture, frequency of using lumbar and heavy material lifting, monotonous repetition of working operation and noise(p<0.05). No significant difference was shown in the factor of convenience of chair. 4. In the daily living characteristics, low back pain shown the significant differences in walking time a day, status of health and smoking pattern(p<0.05). there were, however, no significant differences in the aspect of the kind of house and bed, sleeping attitude, driving, riding time on the vehicle, exercising, frequency of cultural life and drinking alcohol. Conclusion: when I see above resultants totally, it appears a higher incidence caused by working environment rather than living habit and then consequently compared to hospital workers, they also have high incidence like others. In order to reduce incidence of low back pain and enjoy the our life we need to educate ourselves preventing program for low back pain and try to effort for preventing of low back pain on each department and individual.

Objectives : To estimate the awareness, treatment and control rate, as well as to identify the awareness-related factors for hypertension. Methods : The study participants were 482 adults (men 206, women 276), aged 45 or over, diagnosed with hypertension and living in Chuncheon. The awareness rate was defined as the proportion of persons among those with hypertension who had previously been diagnosed by a physician. The treatment rate was defined as the proportion of persons who had used anti-hypertensive medication, among those who were aware of their hypertension. The control rate was defined as the proportion of persons who kept blood pressure normal, among those who had been treated for their hypertension. Multivariable logistic regression analysis was carried out for the awareness-related factors using SAS VER 8.1. Results : The awareness, treatment, and control rate were 55,8% (53.4% for men; 57.6% for women), 89.6% (87,2% for men; 91.2% for women), and 34.4% (28.1 % for men; 38.6% for women), respectively. The awareness-related factors included a family history of hypertension (odds ratio[OR], 5.63; 95% confidence interval[95% CI]=1.53-20.72), smoking([Ex; OR 0.38, 95% CI= 0.15-0.96)], [Current; OR 0.28, 95% CI=0.10-0.80]), and alcohol intake ([Ex; OR 3.22, 95% CI 1.03-10.09],[Current; OR 3.36, 95% CI=1.30-8.71]) for men, and education(OR 2.23, 95% CI=1.10-4.53), body mass index(OR 2.72, 95% CI=1.13-6.53), and self-rated health(OR 2.38, 95% CI=1.07-5.30) for women. Conclusions : The awareness rate of hypertension among the middle aged and elderly in Chuncheon was 55.8%. The related factors of awareness were gender specific. Further studies are needed to elucidate the putative reasons for these gender differences.

정진영,Jeong, Jin-Young 대한정형외과스포츠의학회 2011 대한정형외과스포츠의학회지 Vol.10 No.1

Rotator cuff disease is one of the most common shoulder problems. When dealing with patients suffering from rotator cuff disease, whether to perform surgery or not is the most common difficulty faced by the outpatient clinic. Choosing the adequate operation time as well as the method of operation is important when deciding to perform surgery. Selecting the type of non-surgical treatment is an important issue when opting not to perform surgery. This review article will focus on the decision-making process involved in the treatment of rotator cuff disease. 회전근 개 질환은 임상에서 대하는 가장 흔한 견관절 질환이다. 증상을 호소하는 회전근 개 파열 환자를 대하게 되면 수술을 시행할 것인지, 아니면 비수술적 치료를 시행할 것인지의 결정은 진료실에서 당면하는 가장 흔한 과제이다. 그리고 수술적 치료를 선택한다면, 언제 할 것인지, 어떤 수술방법을 선택할 것인지의 결정도 중요하며, 수술을 시행하지 않는 경우는 어떤 치료를 해야 할 것인지 또한 흔히 겪는 문제이다. 본 종설에서는 회전근 개 파열의 경우 언제 수술하나에 해당하는 수술의 적응증과, 수술하지 않는 경우는 어떻게 치료할 것인가? 라고 하는 비수술적 치료의 적응증에 관하여 기술하고자 한다.

정진영,Jeong, Jin-Young 대한관절경학회 2009 대한관절경학회지 Vol.13 No.2

외상성 슬관절 탈구 중 도수 정복되지 않는 경우는 매우 드물며 대개는 관혈적 정복술을 요한다. 본 증례는 도수 정복되지않는 슬관절 탈구에 대한 관절경적 치료 경험으로 자기공명 영상에서 정복을 방해하는 내측 인대 및 관절낭 구조물을 관찰하고 관절경 검사로 확인한 후 대퇴골 내측와가 완전히 관찰되고 관절이 정복 될 때까지 끼어있는 조직을 제거하였으며 인대 봉합이나 재건술은 시행하지 않았다. 술 후 약 4주간의 신전상태에서 고정 후 점진적인 관절운동 및 체중부하 보행을 허용하였다. 3년 추시 관찰에서 경도의 슬관절 불안정성은 있었으나 일상생활에 지장 없었으며 정상범위의 관절운동범위를 회복하였다. Irreducible knee dislocation is a rare injury and often need an open procedure with ligaments reconstruction. This report describes a case of arthroscopic treatment of a patient with traumatic knee dislocation unable to reduce in a closed method. MRI revealed incarceration of the medial collateral ligament and capsule in the medial compartment. And arthroscopic examination confirmed incarcerated medial capsuloligamentous structures which prevented the knee from reduction. Arthroscopic procedure without ligaments reconstruction was complete when the medial condyle was well visualized and the knee reduced. After 4 weeks of immobilization in extension, range of motion exercise and gradual increases in weight bearing was allowed. At the 3- year follow-up, mild laxity was remained but the patient did not have any discomfort of doing ADL activity and showed full range of motion of the knee.

정진영(Jin-Young Jeong),손창환(Chang-Hwan Son),이휘종(Hwijong Yi) 한국정보기술학회 2022 Proceedings of KIIT Conference Vol.2022 No.6

해충 분석을 위해 현장에서 수집되는 영상은 원거리 촬영, 저해상도 센서 사용, 작은 객체 크기 등의 다양한 요인으로 인해 저해상도의 열화 영상이 수집될 수 있다. 이러한 열화 영상은 생성적 적대 신경망 기반의 기존 초해상화 기법으로 인간에게 인지 가능한 수준의 고해상도 영상으로 복원할 수 있지만, 여전히 남아있는 텍스처 정보 부족의 문제로 인해 해충 분석을 위한 딥러닝 모델들의 인식률 저하를 초래한다. 본 논문에서는 텍스처 정보를 개선하기 위해 해충의 부류별 지각 특징을 추출하는 네트워크를 활용한 지각 손실을 모델을 제안한다. 이를 통해서 보다 정확한 정답과의 텍스처 특징 오차를 측정하도록 하고자 한다. For the images collected in the field for pest analysis, low-resolution degradation images may be collected due to various factors such as long-distance shooting, use of low-resolution sensors, and small object sizes. These degraded images can be restored to a high-resolution image that humans can recognize without difficulty using the existing super-resolution method based on a generative adversarial neural network. However, the problem of lack of texture information still remains, which causes a decrease in the recognition rate of deep learning models for pest analysis. In this paper, we propose a perceptual loss model using a network that extracts perceptual features for each pest class to improve texture information. Through this, we want to measure the texture characteristic error with the correct answer more accurately.

연구목적 : 본 연구는 지역사회건강조사를 통해 파악된 우리나라 주요 건강행태(흡연, 음주, 신체활동, 구강건강) 및 건강수준(고혈압 및 당뇨병, 심뇌혈관질환 사망률)의 시군구별 변이를 초래하는 관련요인을 규명하고자 수행하였다. 연구방법 : 연구단위는 2009년 기준 보건소가 설치된 253개 시군구이며, 지역사회건강조사, 통계청, 지방자치단체 기초통계연보 등 2차 자료를 통해 지역특성 DB를 구축하였다. 지역간 변이요인에 대한 규명은 생태학적 분석(선형회귀분석)을 통해 수행하였다. 연구결과 : `남자현재흡연율`은 `지역박탈지수`, `조이혼율`, `인구천명당주점수`, `체질량지수`, `월간음주율`과 양의 관련성을 `고교졸업률`, `주민대상금연교육수`와 음의 관련성을 보였다. `월간음주율`은 `현재흡연율`, `비만율`, `우울감경험률`, `월소득`이 높을수록, `인구천명당주점수`와 `인구1인당공원면적`이 낮을수록 높았다. `1인당자동자등록대수`가 많을수록 `걷기실천율`이 낮았다. 노인의 `저작불편호소율`은 `지역박탈지수`, `주관적구강건강상태`, `경제적이유로인한 치과진료미수진율`, `인구 십만명당치과병원수`로 나타났다. `고위험음주율`, `비만율`, `스트레스인지율`, `노인인구비율`이 높은 지역에서, 그리고 `기초생활수급자율`, `중등도신체활동실천율`이 높을수록 `고혈압평생의사진단경험률`이 낮았다. 또한 `당뇨병평생의사진단경험률`은 `기초생활수급자율`, `고혈압평생의사진단경험률`과 양의 관련성을, `검강검진수검률`과는 음의 관련성을 보였다. `현재흡연률`, `재정자주도`, `실업률`은 `심장질환사망률` 및 `뇌혈관질환사망률`과 모두 관련성이 있었고, 그 밖에 `고혈압평생의사진단 경험률`과 `당뇨병평생의사진단경험률`은 `심장질환사망률`과 `성비`는 `뇌혈관질환사망률`과 관련성을 보였다. 마지막으로 `사고손상경험률`은 도시지역은 `가구균등화소득`, `필요의료서비스미치료율`, `비만율`, 농촌지역은 `노인인구비율`, `투표율`, `우울감경험률`과 관련이 있었다. 특히 `지역박탈지수`는 관련요인을 통제 후 도시지역에서만 `사고손상경험률`과 관련성을 나타냈다. 결론 : 본 연구는 주요 건강행태 및 건강수준의 지역간 변이를 줄이는 정책 마련에 근거자료로 활용할 수 있을 것이다. Objective : This study was performed to investigate the magnitude and pattern of small area variations defined by Si-gun-gu and to explore the factors related to these variations in the prevalences of smoking, drinking, physical activity, oral health, hypertension and diabetes mellitus (DM) management, and cardiovascular death rates, using 2009 Community health survey (CHS) data. Methods : The unit of analysis was 253 counties surveyed at 2009 CHS. Analysis dataset was constructed of secondary data extracted from Korean Statistical Information Service (KOSIS) and data from CHS. Magnitude and pattern of area variations in the given health behaviors and health status were examined with Extremal Quotient (EQ) and Coefficients of Variation (CV) of Small Area Variation Analysis (SAVA). Ecologic analysis using linear regression model was used to explore the related factors with these variations. Results : In all dependent variables, the variations between areas were statistically significant. Variations in smoking rates appear to be positively related with several variables, such as regional deprivation index, crude divorce rate, obesity rate, and number of bars per 1,000 person, and negatively with level of educational attainment, number of smoking cessation program in that area. The variables related with high monthly drinking rate were number of bars per 1,000 person, higher budget for welfare, and less park area (m2) per person. As the number of registered motor vehicles per person increases, the obesity rates became higher and rates of walking exercise decreased. The related factors with rates of physician diagnosed hypertension were proportion of elderly people aged 65 or over and of those with basic needs. Age-standardized cardiovascular disease death rates were found to be related with unemployment rate and low financial independence of that area. The variables related with total injury experience rate were monthly household equalization income, Unmeet health care need, obesity in urban, and Elderly percent, Vote rate, Depressive symptom in rural. In particular, regional deprivation index was associated only in urban after adjusting related factors. Conclusions : These results will help us to set up policy development for population-based health promotion through reducing the gap of health-related indices between area. Further researches are needed to maximize academic value of CHS data.

Objectives : This study was undertaken to examine the metabolomic changes due to gender and diurnal variation at sampling time and to identify an appropriate time point for urine sampling in epidemiologic studies using metabolomic profiles. Methods : Urine samples were collected twice a day (morning and afternoon) from 20 healthy Korean adults after fasting for 8 hours. The metabolomic assay was investigated using H NMR spectroscopy coupled with the principal components analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The metabolites responsible for differentiation between groups were identified through the loading plot of PLS-DA and quantified using Chenomx NMR Suite with a 600 ㎒ library. Results : Metabolites responsible for differentiation in gender and sampling time were creatinine, trimethyl anine oxide (TMAO), hippurate, mannitol, citrate and acetoacetate. Dimethylamine showed difference only as a factor of diurnal time. The level of creatinine was higher in men compared to women, and the levels of citrate, TMAO, hippurate, mannitol, and acetoacetate were higher in women compared to men. The levels of creatinine, TMAO, hippurate, dimethylamine and mannitol were higher in the morning rather than the afternoon while those of citrate and acetoacetate were higher in the afternoon rather than the morning. Conclusions : Since urinary metabolomic profiles varied by gender and diurnal cycle, urine sampling should be performed at the same time point for all participants in epidemiologic studies using metabolomic profiles.
