Objective : As the average lifespan of human increases, osteoporosis and osteoporosis-related fractures have become major health care problems. Despite recent advances in medical treatment, few studies have assessed the recognition of osteoporosis in general adults. This study examined the recognition of osteoporosis and analyzed the relating factors. Method : A population-based sample of 1086 adults in Asan-city, Korea was investigated with questionnaires and height, weight, Information regarding the general characteristics(gender, age, economic state), lifestylef exercise, smoking, alcohol),medical history(progestin, GH, steroid, calcitonin, PTH), demographic parameter, obesity, stress, and family history was collected through an interview using a structural questionnaire. The level of obesity was measured by the body mass index(BMI). BMD(Bone mineral density) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry. Osteoporosis was considered to be T-score below -2.5. Results : The prevalence of osteoporosis increased progressively with age, decreased with BMI and predominant in women by the result of x^(2) -test, T-test. Age, weight, BMI were significantly correlated with osteoporosis by the result of Pearson correlation ana1ysis(P<0.05). And age, gender, BMI, family history of osteoporosis were proved to be significant risk factors of osteoporosis by the result of multiple logistic regression(P<0.05). Conclusion : These results suggest that age, gender, BMI might be the most important risk factors of osteoporosis. And the history taking about family history of osteoporosis is helpful for diagnosing osteoporosis.

In order to obtain an useful information for health management and biological monitoring of lead exposed workers, Authors tried to investigate air lead level and the lead exposed level of workers in lead industry according to occupational category. The subjects in our study were 2074 workers in 7 lead-using industries, and study subjects were divided into 4 occupational categories such as storage battery industry (type 1), primary smelting industry (type 2), secondary smelting industry (type 3) and litharge making industry (type 4). Blood zincprotoporphyrin concentration (ZPP), blood lead concentration (PbB) and urinary δ -aminolevulinic acid (ALAU), hemoglobin (Hb), hematocrit (Hct) were selected as the indices of lead exposure. Personal variables such as age, work duration were also collected. The results were as follows. 1. The geometric mean air lead in 9 lead-using industry was 0.1133±4.3120 ㎎/㎥, and that in type 1, 2, 3 and 4 was 0.1038±3.4952 ㎎/㎥, 0.0429±3.4329 ㎎/㎥, 0.1877±2.5123 ㎎/㎥ and 0.9961±5.2910 ㎎/㎥, respectively. 2. The mean ZPP in 9 lead-using industry was 53.1±28.0 ㎍/㎗, and that in type 1, 2, 3 and 4 was 52.0±24.8 ㎍/㎗, 48.0±16.4 ㎍/㎗, 109.8±85.6 ㎍/㎗ and 74.3±37.8 ㎍/㎗, respectively. There was significant difference in ZPP according to occupational category (P<0.01). The percents of lead workers whose ZPP were above 100 ㎍/㎗ in type 1, 2, 3 and 4 were 4.0%, 1.7%, 34.3% and 21.6%, respectively. 3. The mean PbB in lead-using industry was 26.0±11.2 ㎍/㎗, and that in type 1, 2, 3 and 4 was 25.3±11.1 ㎍/㎗, 26.7±8.8 ㎍/㎗, 50.3±15.2 ㎍/㎗ and 36.4±11.0 ㎍/㎗, respectively. There was significant difference in PbB according to occupational category (P<0.01). The percents of lead workers whose PbB were above 40 ㎍/㎗ in type 1, 2, 3 and 4 were 10.4%, 7.7% 71.9% and 43.2%, respectively. 4. While the correlation of Hb corrected PbB with ZPP was higher than non corrected PbB, the correlation of log-transformed ZPP with PbB was higher than non corrected ZPP. 5. Simple linear regressions of PbB and corrected PbB as independent variable with ZPP, log-transformed ZPP and ALAU as dependent variable were statistically significant (P0.01). Coefficient of determination of corrected PbB with other variables was higher than non corrected PbB. As the result of this study, it was suggested that reconsideration of environmental and biological monitoring program was highly recommended for secondary smelting and litharge making industry.

To investigate the effect of smoking and drinking habit on the health status of lead workers, 220 male workers in lead using industries and 210 male controls were selected for this study. Selected study variables were lead in blood (PbB), zinc protoporphyrin in blood (ZPP), delta-aminolevulinic acid in urine(DALA), hemoglobin (Hb), and hematocrit (Hct). Questionnaire for lead related symptoms (15 symptoms) and smoking and drinking habit was provided to all the workers and filled up by themselves and reconfirmed by physician. The results obtained were as follows; 1. While smoking and drinking rate of lead exposed group were 77.7% and 75.8%, respectively, those of control group were 53.3% and 35.7%, respectively. 2. Mean values of lead exposed indices of lead workers was significantly different from other group. 3. In exposed workers, there was significant differences of DALA between smoker and non-smoker. 4. The neuromuscular symptom prevalence of lead exposure was higher in lead exposed group than non-exposed group. 5. Symptom prealence of lead exposure were higher in drinking and smoking group than non-drinking and non-smoking group. 6. While logistic analysis of positive neuromuscular symptom with categorized blood lead and age, smoking, drinking as categorized independent variables indicated that only blood lead (>40㎍/㎗) was significantly contributed to dependent variable with 95% significant odd ratio confidence interval, logistic analysis of positive constitutional symptom with same categorized independent variables indicated that only age (>40years) was significantly contributed to dependent variable. And logistic analysis of total symptom with same categorized independent variables indicated that blood lead (>40㎍/㎗) and age (>40years) were significantly contributed to dependent variable.

형상기억복합재료를 제조하기 위하여 핫프레스 방법을 이용하여 최적의 제조조건을 도출하였으며 냉간압연에 의해 기지재와 강화재의 계면접합을 강화하여 강도를 증가시켰다. 이러한 방법에 의해 제조된 형상기억복합재료에 대하여 외부 하중에 의한 손상정도와 균열의 발생을 감지하여 균열 발생 및 진전을 억제하는 온라인 모니터링 시스템을 개발하고자 한다. 이를 위하여 음향방출 신호의 파라미터를 이용하여 손상에 따른 최적의 AE 파라미터를 도출하였으며 가열시스템을 이용하여 형상기억합금을 가열함으로써 형상기억합금의 수축에 의한 복합재료 내부에 균열진전을 억제시키는 시스템을 개발하였다. A hot press method was use for the optimal manufacturing condition for a shape memory alloy(SMA) composite. The bonding between the matrix and the reinforcement within the SMA composite by the hot press mothod was strengthened by cold rolling. In this study, the objective was to develop an on-line monitoring system for the prevention of the crack initiation and propagation by shape memory effect of SMA composite. Shape memory effect was used to prevent the SMA composite from cracking. For the system to be developed, an optimal AE parameter should be determined based on the degree of damage and crack initiation. When the SMA composite was heated by the plate heater attached at the composite, the propagating cracks appeared to be controlled by the compressive force of SMA.

( Dong-woo Lee ),( Hwa-kyung Shin ) 한국감성과학회 2019 한국감성과학회 국제학술대회(ICES) Vol.2019 No.-

Purpose: Dynamic Myofascial Release(DMFR) was conducted as it was expected to be effective improving body movements and Chronic Low Back Pain when the MFR and joint mobility were mobilized in a direct or indirect manner to approach the problematic area. Methods: 30 patients with non-specific low back pain were selected and randomly divided into DMFR group (N = 15) and control group (N = 15). The control group was received treatment with limited of trunk's ROM and DMFR group was received DMFR. Dynamic Myofascial Release is a separate therapeutic area from joint mobilization. Because Dynamic Myofascial Release is a therapeutic method for myofascial that is the connective tissue that connects the whole human body. And because the patient and the therapist are involved in the treatment at the same time, and the patient's active posture or participation includes low intensity movements that can be released only by breathing. The other is that the therapeutic action that causes movement around the fixed axis is extremely restrained as if it reminds of slow video and static energy therapy Results: The results showed that the mobility and standing balance of the trunk increased significantly compared to the control group (Lee Dong-woo et al, 2019). Dynamic Myofascial Release is expected to help improve trunk movement and non-specific low back pain, and should be used properly with Myofascial Release (P<.05) Conclusions: Dynamic Myofascial Release(DMFR) was effective. These of direct or indirect methods to access problematic areas, including MFR and joint mobility, was effective in improving body movements and lumbar pain.

이용만,안규동,이성수,함정오,김화성,리갑수,이병국 순천향의학연구소 1996 Journal of Soonchunhyang Medical Science Vol.2 No.2

근접작업이 시력약화의 원인이 될 수 있는가를 알아보기 위하여 전자부품을 제조하는 2개 사업장에서 1991년에서 1993년까지 입사한 근로자들 중에서 근접작업으로 인정되는 마이크로칩을 조립하는 근접작업자 306명을 조사군으로, 대조군은 세탁기 타이머 및 일반 기계기구를 조립하는 작업자 154명, 계 460명을 선정하였다. 이들 대상자는 1991년 입사자는 1993, 1994, 1995년 시력을 조사하였으며, 1992년 입사자는 1993, 1994, 1995년 3년동안 조사를 하였으며, 1993년 입사자는 1994, 1995년 2년간 시력을 조사하였다. 대상자 중에서 입사시 안경을 착용한 근로자는 82명(17.8%)이었다. 따라서 남자 근로자와 안경착용자를 제외한 여성 근로자들 335명만을 추적 조사하여 다음과 같은 결론을 얻었다. 조사군에서 입사시 시력 1.0 이상이었던 근로자의 분포는 취업 1년 후 약 25-35% 정도 감소하였으며, 2년후에는 약 40-60% 정도의 감소를 나타내었고, 3년 후 약 50-65% 정도로 감소하였고 4년후에는 약 65% 이상 감소하였다. 그러나 대조군에서는 1.0 이상의 시력을 보였던 근로자들의 비율이 취업 1년 또는 2년 후 15-30%의 감소를 보이고 있으나 그 이후에는 큰 변동이 없었다. 이들의 시력변화를 근무년수에 따라 알아보기 위하여 조사된 시력을 순위변수로 하여 Kruskall-Wallis 검정을 시행한 결과 조사군, 대조군 모두에서 근속년수에 따른 순위의 합의 평균이 년차적으로 유의하게 감소하였으나, 입사시부터 근속년수에 따른 조사군과 대조군과의 순위합의 평균에 의한 시력차 비교에서 입사시 조사군의 순위합의 평균이 유의하게 높았던 것이 근무기간에 따라 대조군의 평균이 높아지면서 통계적 유의성이 없고 대체적으로 1년 이후부터 변화가 적은 것으로 나타나 근접작업으로 인한 시력약화를 추정할 수 있었다. This study was carried out to investigate that the close distance works were associated with decreased visual acuity. 306 workers were subjects who had been recruited from 1991 to 1993 in two electronic parts manufacturing factories, and 154 workers were controls who had been employed from 1991 to 1993 in launder machine timer and general machine assembly factories. Subjects who had been employed in 1991 and 1992 were follow up from 1993 to 1995, and subjects who had been employed in 1993 were from 1994 to 1995. The male workers as well as glasses wearing workers were excluded. Only 335 female workers were followed up to study the change of visual acuity. The results were as follows; The rate of workers with visual acuity over 1.0 at recruit year in subjects group was decreased about 25-35% after 1 year, 40-60% after 2 years, 50-65% after 3 years, and 65% after 4 years. While, the rate of workers with visual acuity over 1.0 at recruit year in control group was decreased about 15-30% after 1 or 2 years, and there was no more additional visual acuity reduction after then. Kruskall-Wallis test was performed to investigate the change of visual acuity in subject and control group by work duration. The means scores of ranks in both group were significantly decreased by work duration. The mean scores of ranks in subject group at recruit year were significantly higher than those in control group at recruit year, but these differences were disappeared after 1 year work. Therefore, this suggest that close distance workers may be affected their visual acuity.

이병국,이숙,김용배,리갑수,김화성,황규윤,장봉기,이성수,안규동 순천향대학교 산업의학연구소 1999 순천향산업의학 Vol.5 No.1

To clarify the effect of occupational lead exposure on renal function 241 lead workers working and 56 non lead workers were studied in 5 lead acid battery industries. Study variables for renal effect were urinary N-acetyl-β-D-glucosaminidase(NAG), urinary total protein(U-TP), blood urea nitrogen(BUN), serum creatinine(S-Cr), and serum uric acid(S-Ua). On the other hand, blood lead(PbB), zinc protoporphyrin in whole blood(ZPP), and delta-aminolevulinic acid in urine(δ-ALA) were selected for the variables of lead exposure. Information on age, work duration, smoking and drinking history were also obtained. The results obtained were as follows. While the mean values of lead exposure indicators of lead workers were significantly different from non-exposed ones, the mean values of BUN, U-TP and S-Cr of renal function indicators of exposed were also different from non-exposed. BUN, U-TP and NAG showed statistically significant correlation with PbB and ZPP, and NAG revealed also statistically strongly significant correlation with δ-ALA. On multiple regression using renal fuction indicators as a dependent variable and δ-ALA, age, work duration,lead exposure,smoking and drinking as independent variables, only δ-ALA contributed to NAG.
