For the better knowledge to find out the possible causes of high industrial accident rate in small-scale manufacturing industries, questionnaire study was conducted with the workers who worked in the factories with high industrial accident rates and those with no accident rates in a defined period. Three hundred and seven workers(male:271, female:36) classified as industrial accident group who selected from factories which showed higher industrial accident rate that average rate of manufacturing industries. One hundred and fifty eight workers(male:145. female:13) were selected from factories without any accident rate during the same time period of industrial accident group. 27 items of questionnaire concerning to the knowledge and attitude on industrial safety and health were provided to all 465 workers and the comparison results of questionnaires between two groups are as follows; 1. While 50.6% of control group understood well the regulation about health and safety, only 35.8% industrial accident group understood well about the regulation and the rate of understanding of regulation was particularly low in workers whose age were young or whose work duration was short. 2. While most control workers (86.7%)thought that worker’s own fault was the primary cause of industrial accident, 63.2% of industrial accident group answered their own fault as primary cause of industrial accident and significantly differed from control group. 3. The control group showed high percentage of happy feeling during their work(42.7%) than industrial accident group(27.4%). The main cause of unhappy feeling during their works was overload in both group. 4. To the question about most important concerning topic for industrial safety and health in their factories, accident prevention was highest in both group ( control group: 67.1% and industrial accident group:42.0%) as a overall but the achievement of desired goal was highest percentage in industrial accident group workers whose work duration were less than 3 years. 5. The non-wearing rate of proper personal protective equipment was differed between two group(control:8.1% and industrial accident group:26.9%). The main reason for non-wearing of personal proctective equipment was inconvenient.

최현주,성병우,최흥국,서재현 인제대학교기초과학연구소 1998 자연과학 Vol.2 No.-

본 논문에서는 DCT(discrete consine transform)를 이용하여 영상 데이터를 공간 영역에서 주파수 영역으로 변환하여 주파수 영역별로 분해한 뒤, 윤곽선 추출과 압축을 동시에 하기 위한 여러 양자화 테이블을 적용하고, IDCT(Inverse DCT)를 이용하여 복원한 결과를 비교 분석함으로써, 보다 정확한 윤곽선을 가진 영상을 추출할 수 있는 양자화 테이블을 구했다. 이 양자화 테이블을 DCT 처리된 영상에 적용했을 때 윤곽선과 압축 효과를 가진 영상을 얻을 수 있었다. In this paper, we transform image data from spatial domain to frequency domain using DCT, decompose it into each frequency band. We apply various quantization table for edge detection and compression simultaneously. We researched a quantization table for extracting image with exact edge, as compare and analyze restored images using IDCT. When we applied this quantization table to the DCT transformed image, acquired the image with edge and compression effect.

To determine the factors affecting development and recovery of symptomatic vasospasm. the author analysed the results of patients with ruptured intracranial aneurysms treated by nimodipine and prophylactic “triple0H” therapy. From January 1991 to December 1995. 199 patients underwent surgery for ruptured intracerebral aneurysms. Combined hypervolemic hemodilution was initiated at the time of admission. Induced hypertension was added immediately after surgery(aneurysmal neck clipping). All patients received nimodipine intravenously or orally until the 14th day of SAH Sixty patients underwent surgery on Day 0 through 2 after attacks of subarachnoid hemorrhage(Goup A) 105 patients on Day 3 through 14(Group B). and 35 patients after Day 14(Group C). Of 199 patients. 76(38%) patients suffered from symtomatic vasospasm. Symptomatic vasospasm occured in 34% of Group A patients. 33% of Group B patients. and 5% of Group C patients. Symtomatic vasospasm occured more frequently in the older age group. the Fisher group 3 and Hunt & Hess grades 3, 4 and 5 groups. Of 76 patients who suffered from symptomatic vasospasm. 47(62%) patients recovered completely. The author analysed the relationship between recovery rate and sex, age. Hunt & Hess agrde and Fisher group among these 76 patients. Recovery rates between these groups were not significantly different. Based on this experience the author believes that Hunt-Hess grade. Fisher group and age are important factors affecting symptomatic vasospasm development.

정보화근로사업으로 인한 관련산업의 고용유발효과 분석 : 산업연관분석 (Input-Output Analysis)기법의 적용 An Application of the Input-Output Analysis

박광국,주효진,최병기 한국정책학회 2002 韓國政策學會報 Vol.11 No.3

본 연구는 정보화근로사업으로 인한 관련산업의 고용유발효과가 어느 정도인가를 알아보기 위해 산업연관분석(I/O) 기법을 적용하여 그 효과를 추정하였다. 이를 위해 1998년부터 2000년까지 한국전산원에 정보화근로사업 예산지출내역서를 보고한 7개 중앙행정기관(행정자치부. 외교통상부, 건설교통부, 보건복지부. 법제처, 대검찰청, 기상청)을 대상으로 하였으며, 정확한 추정을 위해 한국은행에서 1998년을 기준으로 작성하여 2001년 7월에 발간한 산업연관표(인장표)를 이용하였다. 산업연관분석을 위해 먼저 정보화근로사업의 예산지출내역을 정보화기반조성 예산지출부분과 인건비 지출부분으로 구분한 다음 각 부문별 예산지출내역을 산업연관표의 분류기준에 맞추어 재분류하였다. 또한 산업연관분석에 필요한 산업부문별 생산유발계수와 고용유발계수를 도출하였다. 분석결과, 정보화기반조성 예산지출로 인해 45,999명의 고용유발효과가 있었으며. 인건비 예산지출로 인해 2,020명의 고용유발효과가 있는 것으로 나타났다. 따라서 전체적으로 정보화근로사업으로 1998년부터 2000년까지 약 307억원의 예산지출을 통해 약 48.019명의 고용유발효과가 관련산업에서 발생한 것으로 추정되었다. The purpose of this study is to estimate employment induced effects produced by the IT New Deal by introducing the method of the input-output analysis. The seven central governmental agencies were sampled because they reported the whole budget data related to the IT New Deal from 1998 to 2000. For the elaborate estimate, the 「1998 Input-Output Table: Extended Version」 released by the Bank of Korea on July, 2001 was used. The analysis was conducted according to the following steps. First, the budget outlays of the IT New Deal Program were reconstructed based on the classification system of the input-output table. Second, the coefficients of production and employment induced by the industrial sector were drawn in order to estimate the whole effects resulting from the IT New Deal. The analytic results showed that employment induced effect of 45,999 persons was estimated with the budget expenditure invested in purchasing infrastructure equipments and employment induced effect of 2,020 persons was produced with the budget expenditure used in hiring manpower for the IT New Deal.

AMPS 시스템과 주파수를 공유하는 CDMA시스템의 링크 해석

문병현,손병국,최정희 대구대학교 과학기술연구소 1999 科學技術硏究 Vol.5 No.5

In this paper, the forward and reverse link cellular capacities analysis of code division multiple access (CDMA) is performed when the systems are sharing the same frequency band. It is assumed that the frequency reuse pattern K=5 is used for the analysis. Formule that describe the relationship between the number of CDMA and AMPS users for a given carrier to interference ratio (GI) of each are presented. In the comparison of the forward and reverse link analysis, forward link is smaller than reverse link. Therefore, the system capacity depends on the forward link rather than the reverse link.

정부혁신의 길 : 레드테이프에서 결과중심으로 From Red Tape to Result-Oriented Perforrnance

김병섭,박광국,조경호,최외출 영남대학교 지역발전연구소 1997 새마을지역개발연구 Vol.21 No.-

After the adoption of local autonomy, local governments have tried to enhance the local competitive power by eliminating the bureaucratic dysfunction, such as red tapes, formalism, and so on. This study, however, investigates to find out the eufunction as well as the malfunction of red tape. With the research hypotheses which are drawn from the literature review, the survey was conducted with the sample of 1,023 subjects. Our analysis shows three interesting findings. First, the level of fomalization and red tape is higher in the public rather than the private sector. Second, the level of goal ambiguity which is highly correlated with that of formalization is higher in government organizations rather than private ones. Finally, the level of both organizational commitment and organizational loyalty is higher in the public sector, compared with the private sector. Therefore, these findings suggest that the chief executive of government organization should pay more attention to enhance the morale of government employees. Otherwise, the bureaucratic pathology which decreases the organizational productivity may be prevalent in the public sector.

김남수,최성우,김진호,함정오,박해윤,안규동,이병국 大韓産業醫學會 2007 대한직업환경의학회지 Vol.19 No.4

목적: 우리나라에서 납에 직업적으로 노출되지 않은 일부 중년 성인들의 골중납량과 혈중납량의 수준과 상호관련성을 알아보기 위하여 40세 이상 남자 86명 여자 51명 총 137명을 대상으로 본 연구를 시도하였다. 방법: 연구변수로 골중납량인 경골납량,혈중납량을 택하였다. 경골납량은 K-shell XRF를 이용하여 각 대상 자들을 30분간 측정하였고,혈중납량은 원자흡광광도계법으로 분석하였다. 결과: 총대상자 137명의 경골납량의 평균±표준편차는 3.49±4.99 μg/g이었으며, 남자와 여자는 각각 3.90± 4.88 μg/g 및 2.80±5.14 μg/g이었으나 양군 평균의 통계적 차이는 없었다. 한편 총대상자 137명의 혈중납량의 평균±표준편차는 3.70±1.35 μg/dl이었으며,남자와 여자는 각각 3.93±1.25 μg/dl 및 3.30±1.42 μg/dl이었으나 양군 평균의 통계적 차이는 없었다. 음주,흡연 및 BMI를 통제한 후 혈중납량을 종속변수로 한 중 회귀분석에서 연령은 양의 영향을 주는 변수로 나타났다. 여자대상자만을 대상으로 한 중 회귀분석에서 교란변수를 통제한 후 연령은 경골납량에 경계수준의 양의영향을 나타내었다. 결론: 40세 이상의 우리나라 중년성인의 경골납량의 평균±표준편차는 3.49±4.99 μg/g이었으며,혈중납량의 평균±표준편차는 3.70±1.35 μg/dl이었다 혈중납량은 연령과 성과 유의한 양의 관련성이 있었으나,골중납량은 여자에서만 연령과 경계수준의 유의한 관련을 나타냈다. Objectives: In order to investigate the level and the association between bone lead and blood lead levels of non-occupationally, lead-exposed Koreans, the authors studied the lead biomarkers of 137 middle aged Koreans (86 males and 51 females) older than whose age were above 40 years. Methods: The tibia lead level was selected as the bone lead indicator of cortical bone, and the blood lead level was also measured. The tibia lead level was measured by K-shell XRF with 30-minute measurement of each subjects. The blood lead level was analyzed by AAS method. Results: The mean (SD) of the tibia lead level of the 137 study subjects was 3.49 (4.99) ,㎍/g, and tended to be higher. The mean (SD) of tibia lead level in male subjects (was 3.90 (4.88) ㎍/g) and larger than in that of female subjects (2.80 (5.14) ㎍/g), but without no statistical significance was observed. The mean (SD) of blood lead level of all total subjects was 3.70 (1.35) ,㎍/dl, and tended to be higher. The mean (SD) of blood lead level in male subjects (was 3.93 (1.25) ㎍/dl) and larger than in that of female subjects (3.30 (1.42) ㎍/dl), but without no statistical significance was observed. In multiple regression analysis of blood lead levels after adjusting for covariates, age was a significant independent variable. A weak association of age with tibia lead in female subjects was also observed in multiple regression analysis. Conclusion: The mean (SD) of tibia and blood lead levels of middle aged Koreans whose ages were over 40 years old were 3.49 (4.99) ㎍/g and 3.70 (1.35) ㎍/dl, respectively. Age and sex were positive predictors of blood lead level in multiple regression analysis after controlling for the covariates. However, in multiple regression analysis whereas age was weakly association with tibia lead level only in female subjects in multiple regression analysis.
