  • Objectives: The study was evaluated exposure variation and daily absorption level of cadmium, lead concentration of ambient air of monthly data from 1999 to 2017 for main exposure factor in outdoor workers. Methods: Based on the monthly data from 'The annual report of air quality in Korea from 1999 to 2018' in 'Air Korea' website in the Korean Ministry of Environment. The monthly data of PM2.5, PM10, cadmium, lead concentration of ambient air were recalculated to average, minimum, and maximum. And these data were combined to Asian-dust exposure data from 'The annual report of Asian-dust·smog in 2017' of National Institute of Meteorological Sciences in Korea. Results: Geometric mean(minimum-maximum) concentration in ambient air of monthly data were 0.0017 (ND-0.2015) mg/㎥ in cadmium and 0.0467(ND-0.8554) mg/㎥ in Pb from 1999 to 2017. Both of Cd and Pb concentration in ambient air showed the highest concentration in January and the lowest in August among annual variation from 1999 to 2017. PM10 and PM2.5 level showed the highest in March(PM10) and February (PM2.5) the lowest in August both of PM10 and PM2.5. Discussion: Based on exposure data and prior reports, daily Cd absorption was estimated to 0.013(ND-1.511) mg/day from respiration and 1.89 mg/day from daily food(25.2 mg/day of daily Cd intake). In case of Pb, daily absorption was estimated to 0.350(ND-6.416) mg/day from respiration and 1.38-1.71 mg/day from daily food intake. Conclusion: Cd and Pb with Asian-dust have high influential factor to increase the Cd and Pb exposure at Winter and Spring season in outdoor workers.

  • MMD의 외과적 치료에서 소아에서는 직접 및 간접적인 혈관문합술을 병합하거나 아니면 간접적인 혈관문합술들을 병합하여 시행하는 경향이 있고, 성인에서는 혈관의 직경이나 MMD의 진행속도로 보아 STA-MCA 문합술과 같은 직접적인 수술이 많이 활용되고 있으나, 소아나 성인에서나 모두 공통적으로 보다 넓은 뇌표면에 여러 가지 수술방법을 병합하는 것이 좀더 광범위한 범위에 뇌혈류 공급을 증가 시키는데 도움이 된다고 보는 경향이다. 수술의 적응증은 혈관조영상에서의 나타난 질병의 정도보다는 acetazolamide를 이용한 PET 나 SPECT 검사로서 뇌혈류 예비량에 기준을 두고 있는 현상이 혈류 역학적으로도 합리적인 것으로 보인다. 수술후 합병증을 줄이려면 수술중에 정상탄산, 정상체온, 정상혈압을 유지 시킴과 동시에, 수술직후 통증관리도 철저히 하는 것이 매우 중요하다.

  • Background: Ovarian cancer is an important cause of mortality in women. The aim of this study was to evaluate the incidence and mortality rates and trends in the Iranian population and make predictions. Materials and Methods: National incidence from Iranian annual of National Cancer Registration report from 2003 to 2009 and National Death Statistics reported by the Ministry of Health and Medical Education from 1999 to 2004 were included in this study. A time series model (autoregressive) was used to predict the mortality for the years 2007, 2008, 2012 and 2013, with results expressed as annual mortality rates per 100,000. Results: The general mortality rate of ovarian cancer slightly increased during the years under study from 0.01 to 0.75 and reaching plateau according to the prediction model. Mortality was higher for older age. The incidence also increased during the period of the study. Conclusions: Our study indicated remarkable increasing trends in ovarian cancer mortality and incidence. Therefore, attention to high risk groups and setting awareness programs for women are needed to reduce the associated burden in the future.

  • Purpose : The purpose of this study was to examine the degrees of turnover intention among Korean staff nurses(N=175) and to identify discriminating factors of their turnover intention. Method : The data were driven from a larger study and staff nurses who had worked more than 1 year as nurses were included in the analyses. The original data were collected from May 1999 to March 2000. Descriptive and discriminant analyses were utilized. Results : 87% of the participants reported turnover intention. Nurses were grouped into three group(GP)s depending on the frequencies of turnover intention: Never GP(N=23), Sometimes GP(N=107), Frequent GP(N=43). With three GPs, two functions were produced and only function 1 was significant that significantly discriminated Never and Frequent GPs. Additional discriminant analysis with only Never and Frequent GPs produced function classified 93% of the participants correctly into two GPs. Sub-dimensions of work satisfaction were significant discriminating factors. Nurses who are satisfied with doctor and nurse relationship, pay, and hospital administration tend to report no intention in turnover. Conclusion : Based on the findings of this study, possible managemental intervention for increasing interpersonal skills and assertiveness of nurses, inviting medical residents in ward team meeting, increasing incentives or baseline adjustment of annual income for registered nurses were suggested.

  • This paper is based on the records of researching the patients with cancer in the Chunnam National University Hospital from January 1990 to December 1999 and referred to the Korea Cancer Center Hospital's annual report. The results are as the following : 1. Along the total O.P.D 5,680,284, the patients of therapeutic radiology are 201,367 in $3.55\%$ 2. Among the 12,404 cancer patients, stomach cancer patients are $2,048(16.51\%),\;liver\;cancer\;patients\;are\;1,490(12.01\%),\;lung\;cancer\;patients\;are\;1,418(11.43\%)\;cervix\;and\;uterus\;cancer\;patients\;are\;1,102(8.88\%)$ and sexual ratio of male to female appeared 1.38 : 1 Therefore, male cancer patients are more than female patients. 3. The age distribution of cancer was $2,791(22.50\%)\;by\;55{\sim}64\;age,\;2,582(20.82\%)\;by\;45{\sim}54\;age,\;and\;2,530(20.40\%)\;by\;65{\sim}74\;age.\;Therefore,\;the\;60\%\;of\;all\;cancer\;patients\;were\;45{\sim}75$ ages. 4. Among the 9,815 therapeutic radiology patients, $1,755(17.89\%)\;are\;in\;the\;uterus\;system,\;1,534(15.63\%)\;are\;in\;the\;head\;and\;neck,\;1,519(15.48\%)$ are in the lung. Therefore, the proportion of three kinds of therapeutic radiology patients is about $50\%$. 5. The occupational distributions of 12,404 cancer patients$(90{\sim}99\;year)\;are\;2,795(22.53\%)\;by\;orderly\;farmers,\;2,763(22.28\%)\;by\;house\;wives,\;586(4.71\%)\;by\;businessmen,\;and\;391(3.15\%)$ by public service personnel. Industrial, miners, forest men, soldiers didn't nearly appear. 6. The number of patients of cancer diagnosis was $9,431(76.03\%)\;by\;the\;biopsy\;of\;primary\;region,\;and\;2,201(17.74\%)$ by clinical examination Therefore, those two kinds of methods took a propertion of about $94\%.\;The\;number\;of\;deceases\;on\;departments\;was\;153(32.42\%)\;in\;PD,\;133(28.18\%)\;in\;GI,\;63(13.35\%)$ in GS. Therefore, those three kinds of deceases took a proportion of about $74\%$.

  • Objectives: The study evaluated correlations among monthly PM2.5, PM10, Cd, Pb concentrations and the number of Asian dust days. Methods: Based on data from 'The annual report on air quality in Korea from 1999 to 2017', concentrations of PM10, PM2.5, Cd, Pb, and the number of Asian dust days were recalculated to mean, standard deviation, minimum, and maximum. Correlation coefficients were calculated among PM2.5, PM10, Cd, Pb, and Asian dust days. Results: Asian dust days were correlated only with PM10 among the four factors of PM10, PM2.5, Cd, and Pb. The four factors of PM10, PM2.5, Cd, and Pb were very significantly correlated with each other (p<0.01). Their correlation coefficients for PM10 were 0.800 for PM2.5, 0.823 for Cd, and 0.892 for Pb. PM2.5 was also correlated strongly with Cd (0.845) and Pb (0.830). Cd had a correlation with Pb of 0.971. The maximums of PM2.5, PM10, and Pb were shown to exceed the atmospheric environmental standard of Korea, which necessitates national continuous exposure control. Based on exposure data, Asian dust days were thought to be an exposure factor for Cd and Pb. Conclusion: Asian dust might be a factor in Cd and Pb exposure. National exposure controls are required for exposure to PM2.5, PM10, Cd, and Pb.

  • Various housing measures are needed for the rapidly aging society of Korea. In particular, the welfare policy for the elderly has changed towards the community care. Taking this fact into consideration, it is necessary to have the establishment of a system that offers the elderly appropriate welfare services at their appropriate residence (ageing in place) for the effectiveness of the community care. In this aspect, there are a number of implications to Korea to study merits and demerits of the Health Facilities for the Aged (HFA) in Japan. The society of Japan has been rapidly aging since 1970, and Korea is to face the same situation. As for the data of this study, a total of 2,393 facilities (as of November 1999) mentioned in the annual report of the Japanese Ministry of Health, Labor and Welfare were classified based on types of their establishment: (1) free-standing structures (603 facilities); (2) annexes to hospitals (981 facilities); (3) annexes to welfare facilities (511 facilities); and (4) annexes to clinics (298 facilities). Next, 239 facilities were selected through taking a sample of 10 percent from each type of the HFA mentioned above. This was done through the random sampling method with the computer program of MS EXCEL. The Implications of the results of analyses are as follows. First, most of the health facilities were planned with the scale that was larger than the scale of standard special nursing homes in terms of the total floor area. Precise equations that were to obtain precise results of the scale of the HFA and the appropriate number of residents were obtained through the method of the regression analysis. Korea and Japan have similarities in terms of culture, society and family relations; however, the two countries also have differences in terms of the application of laws on the establishment of houses, hospitals, and welfare facilities. As for planning the scale of the HFA, the realities of Korea should be considered. Second, as for the functional aspect of the HFA with a condition of returning home, the place before and after the HFA showed the pattern of 'from a residential place to a residential place' and 'from a hospital to a hospital.' This reveals a close correlation with the types of the HFAs and operational ways of the facilities. Its cause is considered to be the aspect of the operation and management of the HFA rather than the aspect of its function of providing services in association with medical and health facilities. Therefore, when intermediate welfare facilities are considered in Korea, it is strongly advised to consider the problem of annexes to other facilities and efficiency of sharing of the facilities in terms of its operation and management.

  • 통계청에서 최근에 발표한 한국인 인구통계 자료와 미국 학술원 산하 '방사선의 생물학적 영향 위원회'의 최근 보고서(BEIR-V)의 수정 상대위험 투사모델을 적용하여 한국인의 방사선 피폭에 의한 초과 암발생 위험도를 평가하였다. 인구통계 자료로부터 유도한 사소위험도(trivial risk) 및 계산된 방사선유발 초과 암 위험도를 비교한 후 사소위험도의 수준으로 개인의 피폭선량을 유지하기 위한 국내 원전의 안전운영 목표치를 유도하였다. 방사선 피폭 유발 초과 암 위험도는 0.1 Gy의 단일피폭의 경우에는 $5.5{\times}10^{-3}$, 1.0 mGy/y로 생애연속 피폭 시엔 $3.7{\times}10^{-3}$인 것으로 평가되었다. 한국인의 모든 원인에 의한 기저사망 위험도 및 사소위험도는 각각 $5.2{\times}10^{-3}$$5.2{\times}10^{-6}$인 것으로 예상되었다. 한국인의 사소위험도 및 방사선 위험도 평가 결과로부터 유도한 국내 원전운영의 안전목표치는 대략 0.05 mSv/y로, 이 값은 미국 원자력규제위원회(USNRC)가 연방규제법 10CFR50 부록 I에서 제시하고 있는 ALARA 지침값과 거의 동일한 값으로 밝혀졌다.
