콘크리트 포장 표면처리 방법에 따른 소음 감소 방안 연구

문준범,조윤호 중앙대학교 기술과학연구소 2003 기술과학연구소 논문집 Vol.33 No.-

본 연구는 다양한 표면처리 공법에 따른 소음도를 비교 · 분석하여 소음 감소효과에 적합한 타이닝 방법을 제안하였다. 기존 문헌조사 결과 종방향 타이닝이 소음감소 효과에 우수한 결과를 보인다는 것을 바탕으로 국내 시험도로 일부구간에 표면처리 방법을 적용한 결과는 다음과 같다. 일정간격 18㎜종방향 타이닝이 다른 비교구간보다 약 2~3dB(A) 소음 감소 호과가 있다. 특히, 덤프트럭(100㎞/hr)으로 외부소음 측정시 6.3dB(A)로서 가장 크게 차이가 났다. 반면에 임의간격 횡방향 타이닝이 소음감소 효과가 가장 미비한 것으로 나타났다. 덤프트럭으로 외부소음을 측정하여 주파수 분석한 결과 250~500Hz사이에서 peak frequency point가 발생하는 것을 알 수 있었다. 또한, 승용차의 경우 1000Hz부근에서 소음 발생이 가장 큰 것으로 나타났다. 차량 내부 소음 측정결과 표면처리 방법에 따라 소음 정도가 큰 폭으로 변화하지 않았으나. 차량 외부에서는 크게 변화하였다. 그러므로, 차량 외부의 타이어/포장면에서 발생되는 음이 소음값을 측정하기에 적합하다고 판단된다. 분산 분석결과 표면처리 방법에 따라 소음발생에 크게 영향을 미치는 것으로 나타났다. 따라서 표면처리 방법은 소음도에 중요한 영향을 미치는 인자로 고려가 가능하다고 판단된다. This study tries to compare and analyze the noise effect by various surface treatments, and to propose appropriate tinning methods to reduce noise. As literature reviews, longitudinal tinning is effective to reduce noise made between vehicle tire and pavement surface. The results of this study, which applies surface treatment methods to some sections of test road. Noise 2~3dB is reduced in the section of uniform space 18㎜ longitudinal tinning, while random transverse tinning is ineffective. Especially, the difference of noise reduction is the greatest as 6.3dB(A) at out side noise measured by a dump truck (100㎞/h). As a result of test that measures outside noise and analyzes frequency, the peak frequency point happens between 150 and 500 Hz. The maximum noise of car is measured at about 1000Hz. The interior noise of vehicle is little changed in accordance with surface treatment methods; however, the outside noise is affected by treatment methods. Therefore, it is proved that the outside noise of tire/pavement surface is appropriate to be a standard of noise measurement. As a result of variance analysis, the treatment method could be considered a factor to reduce noise made between vehicle tire and pavement surface because various surface treatments influence noise occurrence.

Plasma fibronectin is an α₂-glyoprotein, which is produced by vascular endothelial cells. Raised level of plasma fibronectin has been observed in diabetic patients particularly in the presence of microvascular complications. However, no available data exist about urine level of this glycoprotein in diabetic patients. We measured urine fibronectin level by ELISA methods in 54 diabetic patients who have microvascular comlications or not. The following results were obtained. 1) Urine fibronectin level(㎍/g creatinine) in diabetic group(1740.0±678.0) is increased compaired with those in normal control group(471.0±59.0). but this results were not significantly different among two groups(P>0.05). 2) Urine fibronectin level(㎍/g creatinine) was significantly increased in patients with nephropathy (6188.0±3144.0) compared with those in normal control group(471.0±59.0) and patients without nephropathy(645.0±251.0)(P<0.001). 3) There were a significant correlation between BUN, creatinine, creatinine clearance, 24hr urine total protein and urine fibronectin level in diabetic patients. Our data suggest that urine fibronectin excretion level might be used as a sensitive guide for diabectic nephropathy.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

연구목적: 정신장애의 정확한 진단과 평가는 임상에서뿐만 아니라 신뢰성 있는 연구를 위해서도 매우 중요하다. Structured Clinical Interview for DSM-IV(SCID)는 임상전문가들이 사용하는 진단도구로서, 비교적 짧은 시간에 정확한 진단을 내릴 수 있다. 본 연구는 한국어판SCID를 개발하고 그 신뢰도를 평가하기 위해 수행되었다. 방법: 국문학자가 포함된 번역위원회를 통하여 연구용판 SCID를 번역한 후, 정신과 의사 2인과 임상심리학자 1인에게 한국어판SCID 실시방법을 교육시킨 뒤 한국어판SCID를 이용한 면담의 평가자간 신뢰도 (interrater reliability)를 검증하였다. 면담 대상은 1999년 2월에서 3월까지 2개 병원 정신과에 치료중인 환자 90명(남:41명, 여:29명)이었다. 결과: 현재 장애(current disorder) 평가에서 주요 우울장애, 기분부전장애, 정신분열병, 알코올 남용 및 의존, 기타 물질 남용 또는 의존, 여러 불안장애들 및 섭식장애 등과 같은 대부분 장애의 kappa값은 .70이상으로 매우 높았다. 그 이외의 양극성 장애, 망상장애, 광장공포증, 감별 불능 신체화 장애 및 건강염려증의 kappa값도 .69에서 .40사이로 수용할 수 있는 정도였다. 평생 장애(lifetime disorder)에서는 양극성 장애(k=.69)와 감별 불능 신체화장애(k=.59)를 제외한 다른 모든 장애의 kappa값이 .70이상이었다. K-SCID 면담시 Ⅰ축 질환에 대하여 흔하게 다중 진단이 내려졌으며, 평균 진단 수는 1.5∼1.7개로 나타났다. 결론: 한국어판 SCID는 신뢰도가 높은 진단도구로 생각되며, 향후 정신질환의 정확한 진단과 임상연구에 유용하게 사용될 수 있다. Objectives: Accurate diagnosis and assessment for psychiatric disorders is crucial for research, as well as for clinical practice. Structured Clinical Interview for DSM-Ⅳ(SCID-RV) is a less time-consumimg and more accurate structured diagnostic interview form. It can be used by clinical professions and is known for a reliable diagnostic tool. Present study was conducted to develop Korean version of SCID-RV and to test the inter-rater reliability. Methods: The authors have translated original SCID-RV into Korean, and revised in parallel with sociocultural background of Korea. Ninety patients from two psychiatric hospitals, both outpatient and inpatient, were interviewed and rated independently by three raters. Results: The kappa coefficients for most of illnesses, such as major depressive disorder, dysthymia, schizophrenia, alcohol abuse and dependency, anxiety disorder and eating disorder were excellent(>0.70) in the evaluation of current disorders. And the kappa coefficients for bipolar disorder, delusional disorder, agoraphobia, undifferentiated somatoform disorder, and hypochondriasis were acceptable(>0.40) in the evaluation of current disorders. In the evalua-tion of lifetime disorders, the concordant rates of all the diagnoses except bipolar disorder and undifferentiated somatoform disorder were excellent. Lack of hierarchy in DSM-Ⅳ allows for multiple Axis I diagnoses. Mean numbers of Axis I diagnoses per subject assigned by the three raters were 1.5-1.7. Conclusions: Our findings confirm that SCID-RV yields highly reliable diagnoses. SCID-RV is recommended for accurate diagnosis in clinical practice and research on psychiatric disorders.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Cho, Jun-Beom,Cho, Ki-Hong,Kim, Se-Hyuk,Shin, Yong-Sam,Lee, Won-Chung,Yoon, Soo-Han The Korean Neurosurgical Society 2005 Journal of Korean neurosurgical society Vol.38 No.4

Objective : There is no acceptable indication and treatment of choice for infantile and child subdural hygroma and there are only a few reports about that in Korea. So the authors studied the clinical findings of infantile and child patients with subdural hygroma to improve the understanding and to suggest a standard treatment method. Methods : The authors retrospectively evaluated the causes, preoperative symptoms, radiological thicknesses, and postoperative results of 25patients with subdural hygroma who received surgical therapy. Results : There were 16boys and 9girls whose median age was 6months[range $2{\sim}120months$]. The main clinical manifestations were seizures, increased intracranial pressure, macrocrania and alteration of consciousness. Radiological thicknesses of the subdural hygroma varied from 7mm to 42mm and postoperative changes of thickness[y] could be expressed with the factor of month[x]: $y\;=\;-1.32\;{\times}\;+11.8$ in subdural drainage, and $y\;=\;-1.52\;{\times}\;+14.9$ in subduroperitoneal shunts. Of the 25patients, 2 [50%] were successfully treated by aspiration, 13 [59%] by subdural drainage, and 9 [69%] by subduroperitoneal shunt. Conclusion : It is suggested that the diagnosis and treatment of subdural hygroma in infants and children should be carefully addressed because of its high prevalence in children, and especially in infants. It is also suggested that the subdural drainage could be primary initial treatment method because it is simpler than a shunt, and since our data show that there is no statistical difference in postoperative recovery duration between the two operative methods.

Purposes: The purpose of this study was to examine the association between risk behaviors and smoking in Korean adolescents. Methods: This study used data from online survey of youth health behavior in 2017. Data from a total of 54,411 people (27,139 male, 27,272 female) were included in the analysis. chi-square test, simple logistic regression, multiple logistic regression were performed using SAS 9.4. Findings: Multiple logistic regression analysis showed that risk behaviors such as drinking alcohol experience, sexual experience, drug use experience and high caffeine energy drinks intake experience had a significant effect on smoking. Adolescents with drinking experience were more likely to smoking than those who had no experience(OR=8.58, 95% CI: 7.67~9.60). Adolescents with sexual experience were more likely to smoking than those who had no experience(OR=4.47, 95% CI: 3.91~5.11). Adolescents with drug use experience were more likely to smoking than those who had no experience(OR=2.32, 95% CI: 1.63~3.32). Also, adolescents with high-caffeine energy drinks intake experience were more likely to smoking than those who had no experience(OR=1.37, 95% CI: 1.23~1.53). Practical Implications: All the risk behaviors were significantly associated with smoking rates. Results of this study suggest that physicians and health workers in medical institutions and health centers should simultaneously serve education and consultation for the smoking cessation as well as for the prevention of risk behaviors.
