This study was conducted to investigate the risk of chronic disease as predicted by abdominal obesity in Korean adult females. Data on 2,738 adult females aged 40~64 yrs was obtained from the 2013~2014 Korean National Health Nutrition Examination Survey. The subjects were divided into normal (n=1,835), abdominal obesity (AO, n=73), and BMI-diagnosed abdominal obesity (BMI-AO, n=505) groups based on the NCEP-ATP III guidelines and by applying the KSSO definition regarding waist circumference. Triglyceride blood levels, fasting blood sugar levels, systolic blood pressure, and diastolic blood pressure were higher in the AO and BMI-AO groups than in the normal group. The HDL-cholesterol levels of subjects in the two abdominal groups were lower as compared to those of subjects in the normal group. The mean adequacy ratio was lower among subjects in the AO and BMI-AO groups than among those in the normal group. Moreover, the NAR and INQ scores of some micro-nutrients in both of the abdominal obesity groups were lower than those in the normal group. Both the AO and BMI-AO groups showed significantly higher risks of hypertriglycemia, hyperglycemia, hypertension, hypoHDL-cholesterolemia, and metabolic syndrome than were shown by the normal group. Notably, as compared to the normal group, the AO group showed higher risk of hypercholesterolemia, hyperLDL-cholesterolemia, hypertriglycemia, and metabolic syndrome than did the BMI-AO group. This finding suggests that it is essential to develop prevention programs including programs for those with abdominal obesity despite their having a BMI within the normal range.

Social needs are increasing due to the increase of degenerative brain diseases because of the aging society. The most common type of degenerative brain diseases is Alzheimer's disease and Parkinson's disease, which makes most of cases. New scientific challenges indicate that gut microbiota are directly associated with the progress of degenerative brain diseases through triggering metabolic diseases, modulating immune response, and changing diversity of microbial community. A high-valuable strategy is proposed for the management of these disorders and as an adjuvant for psychiatric treatment of degenerative brain diseases and other related metabolic diseases through modulation of the gut microbiota including probiotics.

This study tried to identify the problems associated with the posture to be analyzed and tried to suggest guidelines for MSDs(Musculoskeletal Disorders) evaluation based on working posture. A total of 50 jobs from 3 different types of industries(electronics, hospitals, automobiles) were used for MSDs evaluation study which was done by 6 observers. Two indexes were applied to identify the problem in this study which were percentage of agreement and counter-time-error rate. Specifically, ‘counter-time-error rate’ represented a degree of consistency in terms of selecting the posture to be analyzed time after time. Main results of the study were as follows; 1) The average percentage of agreement for representative posture for whole body was relatively higher than that for representative postures for individual body parts, 2) The counter-time-error rate(%) has been reduced as the evaluation process has repeated for the same job. 3) The counter-time-error rate(%) for electronics, hospitals, and automobiles were 63.4%, 61.2%, and 67.3% respectively. 4) The counter-time-error rate(%) for the job with the work cycle of 0.5 to 2 minutes were lower than that of the jobs with the work cycles less than 0.5 minute or greater than 2 minute. 5) The work cycles and the number of trials had significant effects on counter-time-error rate while the types of industries did not have significant effects on counter-time-error rate. Some guidelines could be prepared from the results of the study. Probably, there should have an extension in terms of form and matter for this study in order to have more practical output.

Objective : This study is a descriptive examination related to musculoskeletal disorders and the risk factors between pediatric and adult occupational therapists as a way to provide basic information for the purpose of preventing musculoskeletal disorders.Methods : This study surveyed 101 occupational therapists who are employed at ten general hospitals and social welfare centers in Seoul and Gyeonggi-do, South Korea. A questionnaire was used as the research tool for determining their socio-demographic characteristics, job satisfaction, workload, task frequency, and symptoms of musculoskeletal disorders. The data were analyzed using the SPSS Version 17.0.Results : The waist and back are the areas that pediatric and adult therapists complain about being the most painful. The next problem areas are the shoulders followed by the neck. When reviewing the occurrence of factors that influence musculoskeletal disorders according to the body area, the results show that these factors increased 4 to 15 times depending on the therapist's posture while treating patients, conducting their workload, and frequently doing tasks.Conclusion : The results show that the prevalence rate of musculoskeletal disorders of occupational therapists is significantly higher. To enhance the posture and physical task environment for therapists working in a diverse range of departments, further studies are needed.

Immunoglobulin G4 (IgG4)-related disease is a newly named fibroinflammatory condition characterized by tumefactive lesions that contain dense lymphoplasmacytic infiltrates rich in IgG4-positive cells. Elevated serum IgG4 concentrations also often accompany IgG4-related disease. Many medical conditions that were long viewed as diseases confined to single organs (e.g., Mikulicz disease, type 1 autoimmune pancreatitis, Riedel’s thyroiditis, multifocal fibrosclerosis, inflammatory pseudotumor, mediastinal fibrosis, retroperitoneal fibrosis, and etc.) are now designated as part of the spectrum of IgG4-related disease. The preferred nomenclature suggested by a committee of international experts uses the prefix “IgG4-related-” for individual organ involvement, regardless of the organ system affected. One exception is type 1 autoimmune pancreatitis (IgG4-related pancreatitis). Comprehensive diagnostic criteria for IgG4-related disease and organ-specific diagnostic criteria (e.g., IgG4- related dacryoadenitis and sialadenitis, type 1 autoimmune pancreatitis, IgG4-related kidney disease and IgG4-related sclerosing cholangitis) can aid clinicians in the diagnosis of this erratic condition.

Objective: The aim of this study was to analyze factors indicating preventive removal of mandibular third molars by determining associated symptoms, pathologies, eruption state, position and angulation types of mandibular third molars. Study design: A retrospective study was made of 436 patients(200 females, 236 males), aged between 12 and 81 years (mean: 29.93 years) undergoing panoramic radiographic examinations. Total 700 mandibular third molars were analyzed. They were divided by age, sex, position and angulation of mandibular third molars, bony coverage, and associated pathologies- caries, pericoronitis, periodontitis, cyst, root resorption of adjacent teeth. Results: Among 409 pathologies associated with mandibular third molars, pericoronitis accounted for 34.2%(140 cases), which was the most common lesion, caries in the second and third molars for 28.9%, caries in the second molars for 11%(45 cases). Periodontitis showed in 7%(29 cases). In 4 cases, root resorption of adjecent tooth showed. The position which showed predominant pathologic lesion according to the Pell and Gregory classification was ⅡA(86.5%), followed by ⅡB(71.6%). Mandibular third molars without bony coverage(64.8%) showed pathologies frequently. Conclusions: The removal of mandibular third molars must be determined by the perceived risk if the teeth are not removed. The position and inclination of the third molars, bony coverage, age and sex of patients can be the important evidence in the decision making process.

The purpose of this study was to synthetically examine the relationship between systemic diseases and periodontal diseases. The data of the Fifth Korea National Health and Nutrition Examination Survey were used. SPSS 18.0 for Windows was applied for statistical analysis. The surveyed data were analyzed by using independent sample t-test for the difference between Body Mass Index and clinical test according to the existence of periodontal disease, and X2test for the relationship between periodontal disease and systemic disease. Multiple logistic regression analysis was used in order to figure out the influence upon the existence of periodontal disease prevalence among general characteristics and relevant factors to systemic disease. As results, the value of high density lipoprotein (HDL) and HBA1C were statistically significant, depending on the presence of periodontal disease. As for the relationship between periodontal disease and systemic disease, hypertension (odds ratio 1.362, p<.05), cardiovascular disease (odds ratio 2.118, p<.05), arthritis (odds ratio 1.289, p<.05) and cirrhosis (odds ratio 6.124, p<.05) were statistically significant. In conclusion, the majority of the systemic diseases such as cardiovascular system, diabetes, and liver diseases have been considered to have relationship with periodontal disease. To strengthen oral health education is needed to enhance systemic health as well as oral health. Moreover, basic biological research should be followed to support this surveyed study.

The study targeted Japanese employees who have visited hospital for spinal disorder. The study analyzed work environment and pain relief methods of work-related back pain patients, and the relationship between back pain and other body parts. The purpose of this study was to provide draw up measures for patients with back pain and to provide basic data for the sustainable prevention program. The study result of back pain, in other words, employees suffering from lumbago, had disparity between occupations; the highest number of patients were made up of 16-years or above long-serving employees, and below 5-years of short-serving employees. There were more patients complaining of chronic lumbago than acute lumbago, and patients recognized poor posture as the primary cause of lumbago. Furthermore, 99.5% of spinal disorder patients complain back pain, 23.2% use only alternative therapy, and 15.2% visit clinic and hospital with alternative therapy. Patients showed pain reduction and high satisfaction after using alternative therapy. The study targeted Japanese employees where complement therapy is more generalized than that of Korea, and thus there should be multilateral management programs provided in Korea as well.

In this paper, we present a serious game that can prevent elderly people from brain illness using natural finger interaction and Fumanet exercise. As population of elderly people has continually grown in our society, brain illness like dementia can be naturally observed, which makes treatment cost up rapidly. Hence, we propose Leap-Motion based serious game for elderly people, which uses natural finger motions to interact with game contents. In our approach, we enhance finger motion recognition rate by adding auxiliary conditions that is superior to ordinary Leap-Motion APIs. Finally, we have also carried out user study and quantitative analysis to verify our methods.

목 적 : 확산강조영상은 골격근 손상이 있을 때 조기에 근육의 신호강도 변화를 알 수 있고 양성과 악성 척추 압박골절의 감별 진단에 유용하다고 보고 되고 있지만 질환에 따른 현성확산계수(Apparent Diffusion Coefficient:ADC)의 연구는 많이 보고 되고 있지 않다. 이에 단순 압박 골절과 전이성 척추암이 b value에 따라서 어떠한 변화가 있는지를 알아보고자 본원에서 시행하고 있는 b value 0 400,1400(s/mm²)를 이용하여 각각의 Signal Intensity의 표준화된 값과 물 분자의 확산 정도를 수치화 하는 ADC, 그리고 신호대 잡음비(Signal to Noise:SNR)를 비교하였다. 대상 및 방법 : 2013년 3월부터 2013년 12월까지 MR판독에서 단순복합골절과 전이성 척추암을 의심하는 환자 중 전자의무기록상 확정된 환자로 두 질환 별로 11명씩 총 22명을 대상으로 하였고 평균연령은 각 질환 별로71.2, 56.6세다. 검사장비는 1.5 Tesla Achieva MRI시스템과 Syn-Spine Coil를 사용하였다. Sequence는 DWI SE-EPI Sagittal(Diffusion Weighted Imaging Spin Echo-Echo Planar Imaging Sagittal)영상으로 TR(ms) 1988, TE(ms) 68, FOV(mm) 300, Mat. 128×128, Thk.(mm) 4, Gap(mm) 0.4, Slice 13, b-factor(s/mm²) 0,400,1400의 Parameter를 이용하였다. 데이터 분석은 확산강조영상 b value 0(s/mm²) 영상에서 SI(Signal Intensity)가 높은 질환 부위에 ROI(Region of Interest)를 잡았고 정상부위는 질환부위 바로 위에서 측정하였다. MRIcro Program을 사용하여 b-value 0, 400, 1400(s/mm²)의 영상으로 각각의 SI를 구하였고 b-value의 각 영상을 가지고 Metlab Software를 이용하여 ADC map을 구하여 이 영상을 가지고 MRIcro Program을 사용해 동일한 위치에 ROI를 적용하여 ADC를 구하였다. 데이터 분석은 첫째 두 질환 별로 b value 0 기준으로 400, 1400(s/mm²)의 SI를 표준화하여 비교 분석하였고(SI400/SI0, SI400/SI0) 둘째 두 질환의 정상부위와 질환부위의 ADC와 SNR를 비교 분석하였다. 통계의 유의성은 MS Excel 의 T-Test를 이용하였다. 결 과 : 단순압박골절의 표준화 값(SI400/SI0, SI400/SI0)은 0.47±0.04, 0.23±0.03이고 전이성 척추암의 표준화 값 (SI400/SI0, SI400/SI0)은 0.57±0.07, 0.32±0.08로 나왔고 두 질환 별 표준화 값은 통계적으로 유의하게 나왔다 (p<0.05). 단순압박골절 질환부위의 b value 400(s/mm²)과1400(s/mm²)에 대한 ADC(mm²/s)는 1.70±0.16, 0.93±0.28이고 전이성 척추암은 1.24±0.21, 0.80±0.15로 측정되었다. 두 질환에서 b value 400(s/mm²)에 대한 ADC(mm²/s)는 통계적으로 유의하게 나왔으나(p<0.05) b value 1400(s/mm²)에 대한 ADC(mm²/s)는 유의하지 않았다(p>0.05). 단순압박골절과 전이성 척추암 질환부위의 b value(0/400/1400(s/mm²) 에 따른 SNR 보면 65.61±2.61/36.32±2.92/20.22±2.16, 48.40±2.72/39.27±7.51/23.02±6.25로 측정되었다. 결 론 : 위 연구는 본원에서 검사하고 있는 b value 0,400,1400(s/mm²)을 이용하여 연구를 하였으며 b value 400(s/mm²)에서 두 질환에서의 표준화 된 값과 현성확산계수의 확연한 차이가 있었다. 결론적으로 일반적인 척추 자기공명영상 검사와 병행하여 확산강조영상의 현성확산계수를 가지고 다양한 척추 질환에 적용시킨다면 보다 정확한 진단에 도움이 될 거라 사료된다. 본 연구의 제한점으로 다양한 b value를 적용하지 못했고 성별, 나이, 각 질환의 병기 및 시기, 전이암의 최초 발병 부위를 정립하지 않았으며 측정 부위를 조영제를 사용한 영상이 아닌 단순히 b value 0(s/mm²)에서 고신호 강도가 나오는 곳의 데이터로 결론을 도출한 점은 앞으로 보완해야 할 것이다.

Therapy with appropriate antimicrobial agents is an important component in the management of patients with liver, biliary and pancreatic infection. Acute cholangitis and cholecystitis are common conditions that may result in progressively severe infection. Infectious complications, both pancreatic (infected necrosis) and extrapancreatic (pneumonia, cholangitis, bacteremia, urinary tract infections, and so on), are a major cause of morbidity and mortality in patients with acute pancreatitis. Antimicrobial agents appropriate for initial therapy (empirical therapy or presumptive therapy) for various grades of severity of infections should be used. Local antimicrobial susceptibility patterns should be considered for use.

An 18 years old female patient suffered from cerebrovascular occlusive disease, moyamoya disease, showed a huge cyst in her left mandibular body in the radiological observation. The lesion was asymptomatic and found during routine dental check. She had no experience of traumatic injury on her jaw. The cystic lesion was ovoid with irregular scalloping margin and multilobular image, and occupied the whole marrow space of mandibular body with slight expansion of buccal cortical bone. During operation the lesion showed an empty space covered with grayish white fibrous tissue. The luminal fibrous tissue and underlying bony tissue were curettaged and examined pathologically. In the histological observation the lesion was a pseudocyst lined by thick fibrous tissue. Some large vessels underwent atherosclerotic change, exhibiting thickened vessel walls which were partly distorted with hemorrhage and thrombi, and some small capillaries were extremely dilated with hemorrhage and subsequently resulted in perivascular ischemic change with chronic vasculitis. This mandibular cystic lesion was finally diagnosed as simple bone cyst (SBC) associated with moyamoya disease differentially from aneurysmal bone cyst (ABC), traumatic bone cyst (TBC), periapical odontogenic keratocyst, and central giant cell granuloma. Therefore, it was presumed that the thromboembolic and atherosclerotic vessels of moyamoya disease might increase the hemodynamic pressure of mandibular bone marrow tissue and subsequently was able to induce SBC.

The purpose of this study was to compare the validity of obesity indices among the body mass index (BMI), waist circumference (WC), and body fat percentage (BF%), and to determine which is the most useful index to predict the risk of chronic diseases of elderly people. This study was conducted as a cross-sectional study at welfare centers in Seoul. The total number of subjects was 261 (68 men and 193 women) with age ≥60 years. The distribution of obesity using 3 obesity indices in the subjects with hypertension, diabetes, or arthritis was BF%>WC>BMI in elderly men and WC>BF%>BMI in elderly women. In elderly women, odds ratios (ORs) for hypertension in BMI and WC quartiles were significantly increased in quartile 2 and 3 (p<0.05). The ORs for hypertension, hyperlipidemia, and arthritis in BF% quartiles were significantly increased in quartile 3 and 4 (p<0.05). The BF% was sensitive obesity index for predicting the occurrence of chronic disease in men, and the WC was sensitive index in women. Our results suggested maintaining BMI less than 23.5 kg/m2, WC less than 82 cm, and BF less than 35% in order to prevent chronic diseases in elderly women.
