As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

고온 초전도체 Y₁Ba₂Cu₃O에서 Y의 Sm 치환 효과

김채옥,김필수,김의훈,김재욱 漢陽大學校 基礎科學硏究所 1992 基礎科學論文集 Vol.11 No.-

고온 초전도체 Y₁Ba₂Cu₃O??에서 Y를 Sm으로 치환시켰을 때의 수송 임계 전류밀도와 저항의 측정은 각각 77K와 80-160K범위의 온도에서 조사되었다. 그리고 X-선 회절 분석 및 적외선 투과율 측정은 실온에서 수행되었으며, 시료들은 고상 반응법에 의해서 제조되었다. 한편 치환양이 증가함에 따라서 정상상태에서의 저항값은 증가하는 경향을 보였고, 93K 근처에서 초전도 전이온도 Tc를 갖고 있으며, 치환양에 따라 거의 변화지 않았다. 적외선 투과율 측정결과 날카로운 peak들은 472.78~618.53㎝-1범위에 있었다. 이것은 특이할 정도로의 low-lying plasmalike edge와 낮은 에너지의 전자적인 여기가 존재함을 나타내는 것이다. 수송임계 전류밀도는 43.3~123.9A/㎠ 범위에 있었다. 전이온도 Tc에 상자성 불순물의 영향이 거의 없는 것으로 보아 123phase에서 Y가 고온 초전도성에 주된 역할을 하지 않음을 알 수 있었다. The measurements of the transport critical current density and resistivity of high Tc superconductor Y₁Ba₂Cu₃O?? were made at 77K and in the range of 80~160K. X-ray pellet diffraction and IR transmittance measurements were carried out at room tempemature. The samples in which Y is replaced by Sm were prepared by solid state reaction. As substitution content increased, the normal state resistivity was increased and the superconducting transition temperature Tc near 93K did not change significantly with the substitution content. From the infrared transmittance measurements many sharp peaks were observed in the range of 472.78~618.53㎝?. It indicates that unusual low-lying plasmalike edge and low energy electronic excitation exist. The values of transport critical current densities were in the range of 43.3~123.9A/㎠. From the observation of no significant change in Tc with mangetic rare earth impurities, it could be concluded that Y plays no crucial role in the high Tc superconduction mechanisms at the 123 phase.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

김성철,진병문,김재형,김정배,조진욱,전계록,이승진,김건우 동의대학교 기초과학연구소 1999 基礎科學硏究論文集 Vol.9 No.1

The spectroscopic properties of 9 pads in a urine strip were studied to develop a urine analysis system. From the present work, we determined the wavelength range which could accurately distinguish the degrees of 9 test items. A computer simulation was performed to distinguish the primary color reaction in the urine strips by using the reflectance of the urine strips, the iuminous intensity of light-emitting diodes, and the spectral sensitivity of photodiodes. The simulation results agree well with the experimental results obtained by using a UV-Visible spectrophotometer.

Jae-Wook Kim. 2002. A Study on the Development and Layout Principles of Korean Conversation Textbooks for Overseas Korean children learners. Journal of Korean Language Education 13-2: 67∼85. The existing Korean conversation textbooks were aimed for non-heritage learners(i.e. foreigners) who have no background knowledge of Korea. They were unsuitable for heritage learners(i.e. overseas Koreans) who have some knowledge of Korea. In this paper, it claims that we must reflect the characteristic of overseas Korean children, that they are not absolutely ignorant of Korea, in textbooks for overseas Korean children. It also points out that unlike the existing textbooks that emphasize the four functions of language, we must integrate the teaching of both Korean language and Korean culture from elementary stages. In addition, we have considered the fact that language education for children is less systematic and analytic than the education for adults in presenting the layout principles for Korean conversation textbooks for overseas Korean children. The textbooks emphasize that the heritage students maximally use their background knowledge in Korean and focus on building their fluency. We believe that Korean conversation textbooks that are made considering the characteristics of overseas will increase the pride in one's homeland and improve the Korean skills of overseas Korean children that attend Korean schools.

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.

김일룡,김재영,박종태,최재욱,김해준,염용태 대한산업의학회 2001 대한직업환경의학회지 Vol.13 No.3

목적 : 이 연구는 자동차 조립라인 근로자들의 사회·심리적 스트레스와 작업관련 근골격계 자각증상간의 연관성을 확인하는 데에 있다. 방법 : 경인지역 소재 자동차 회사 두곳의 조립라인에 근무하는 근로자 636명을 대상으로 하여, 근골격계 자각증상에 대해서는 목과 어깨, 팔과 팔꿈치,. 손목과 손, 허리부위에서의 통증, 쑤심, 뻣뻣함, 화끈거림, 무감각 또는 저림 등을 묻는 표준화된 설문지로 질문하였고, 스트레스 정도는 4개 분야, 45개 항목으로 이루어진 Psychosocial Well-being Index 설문지를 배포후 3점 척도를 적용하였다. 이들간에는 카이자승법, ANOVA rm리고 로짓회귀분석을 사용하여 통계적으로 유의한 연관성을 알고자 하였다. 결과 : 1. 수면시간을 제외하고 연령, 근속기간, 결혼여부, 학력수준, 흡연력, 음주력에 따른 상지근골격계 증상의 빈도 차이는 없었다. 2. 30세 미만의 작업자군에서 사회 심리적 스트레스 점수(p-value: 0.0461)와 스트레스 Factor 3 (p-value: 0.0368), Factor 4 (p-value: 0.0053)의 점수가 높았다. 3. 11∼15년의 근속기간을 가진 작업자의 경우 Factor 1을 제외한 PWI(p-value: 0.0001), Factor 2(p-value:0.0001), Factor 3(p-value: 0.0004), Factor 4(p-value: 0.0001)에서 기타의 근속기간을 갖는 동료에 비해 높은 스트레스 점수를 보였다. 4. 미혼자는 Factor 4에서 기혼자보다 높은 스트레스 점수를 보였다(p-value: 0.0068). 5. 수면시간이 6시간 이하인 작업자군은 6시간을 초과하는 작업자보다 PWI(p-value: 0.0087), Factor 2(p-value: 0.0194), Factor 3(p-value: 0.0048), Factor 4(p-value: 0.0314) 등에서 높은 스트레스 점수를 보였다. 6. 스트레스 점수는 정규분포를 이루었으며 정상군과 스트레스위험군간에 증상의 빈도 차이는 없었다. 7. 근골격계 증상이 있는 작업자군은 무증상군과 비교하여 기타 스트레스 점수는 두 군간에 유의한 차이가 없었으나, Factor 2에서 통계적으로 유의하게 높은 스트레스 점수를 보였고(p-value: 0.028), 단변량(OR: 1.02) 및 다변량(OR: 1.04) 로짓 회귀분석에서도 Factor 2가 양의 회귀계수(0.0226; 0.0352)를 보여 증상에 영향을 주는 것으로 나타났다. 결론 : 근골격계 자각 증상이 있는 조립작업자군은 증상이 없는 군에 비해 우울증 항목에서 높은 스트레스 점수를 보였으나 기타 사회적 역할 수행 및 자기신뢰도, 수면장애 및 불안, 일반건강 및 생명력등의 사회심리적 스트레스 항목에서는 두 군간에 유의한 차이를 보이지 않았다. 로짓회귀분석예서도 우울증이 근골격계 증상에 영향을 주는 것으로 나타나서 비록 제한적이지만 우울증에 해당하는 항목인 Factor 2와 증상간의 연관성을 일부 확인할 수 있었다. 그러나 근골격계 증상발현에는 스트레스 이외에도 인간공학적 혹은 알려지지 않은 요인들 중요하게 작용하므로 이들을 통제한 후의 추가적인 조사를 해야 할 것으로 생각된다. Objectives : To determine the relationship between stress Factors and work-related muscul-loskeletal symptoms of assembly line workers in the automobile industry. Methods : A cross-sectional study was conducted in two Factories of automobile manufacturing companies where inappropriate posture and repetitive motions were required. The total number of subjects was 636, and consisted entirely of men. The Age, length of work duration, marital status, education level, smoking status, drinking status, sleeping time and stress scores were investigated according to subgroups of general characteristics. We divided the subjects into a Reference group and a Stress risk group to compare the frequency of the variables between them. The stress scores of the Positive symptom group were compared with the Symptom free group by the t-test. To measure the stress level, the PWI(Psychosocial Well being Index) which consists of 4 Factors, totaling 45 items, was used. A standardized self-reported questionnaire was used to assess the symptoms in workers. The criteria for positive symptoms were based on Operational Definition of Work-related Musculoskeletal Disorders of the NIOSH. Results : 1) The subgroups of Age, Work duration, Marital status, Education level, Smoking status, Drinking status and Sleeping time revealed no differences in frequencies in musculoskeletal symptoms. 2) Higher PWI(p<0.05), Factor 3(p>0.05) and Factor 4(p<0.01) scores were observed in younger workers compared with older workers. 3) The workers who had work durations betwen 11-15 years showed higher PWI(p<0.01), Factor 2(p<0.01), Factor 3(p<0.01), and Factor 4(p<0.01), compared with other work duration subgroups. 4) Singles had higher Factor 4 scores(p<0.01). 5) The sleeping time of less than 6 hours a day expressed a higher PWI(p<0.01), Factor 2(p<0.05), and Factor 3(p<0.01), Factor 4(p<0.05). 6) There was no difference in the prevalence of musculoskeletal symptoms between the Reference group and Stress risk group. 7) The subjects who had Positive musculoskeletal symptoms showed a significant difference in Factor 2 scores compared with the Symptom free groups. 8) According to a univariate logistic regression analysis, Factor 2(OR: 1.02, 95% CI:1.00-1.04, p-value: 0.0291) expressed significant but mild effects on the musculoskeletal symptoms and a multivariate logistic regression showed a statistically significant effect on musculoskeletal symptoms(OR:1.04, 95% CI: 1.01-1.07, p-value: 0.0170). Conclusion : Psychosocial stress scores were not higher in symptomatic subjects compared with those who had no symptoms. Sleeping longer showed a protective effect on symptoms but this was not statistically significant. There was no relationship between the stress scores and musculoskeletal symptoms in social performance and self-confidence, general well-being and vitality. Factor 2(Depression) was statistically significant though its effect was mild. Limited to this study, We could find partial relationship between psychosocial stress(Depression) and musculoskeletal symptoms. So it could therefore be suspected that ergonomic or other unknown factors may be more significant causes of musculoskeletal symptoms but we did not investigate these.
