통계적 공정 모니터링에서 관리 상태일 때 품질 특성치의 모수값은 하나의 값으로 지정하는 경우가 대부분이다. 그러나 관리 상태로부터 공정 모수의 작은 변화는 실제적으로 크게 중요하지 않은 경우, 품질 특성치의 모수 영역은 관리 상태, 무관심, 그리고 이상 상태의 세 영역으로 구성될 수 있다. 이 논문에서는 3개의 모수 영역이 있는 공정에 적용할 수 있는 두 가지 지수가중 이동평균(exponentially weighted moving average; EWMA) 관리도 절차를 제안하고, 제안된 절차의 성능을 Shewhart 관리도 및 누적합(cumulative sum; CUSUM) 관리도와 비교하여 그 효율을 평가하였다.

This study examined green consumption behavior according to the lifestyles of college students. The data were collected from 314 college students in Yeungnam region by a self-administered questionnaire. Frequencies, Cronbach's alpha, factor analysis, cluster analysis, chi-square tests, one-way analysis of variance, Duncan's multiple range tests, Pearson's correlation analysis, and multiple regression analyses were conducted by SPSS Windows V.18.0. According to the result of factor analysis, lifestyles were categorized into six factors: thrift-saving type, enthusiastic activity type, brand ostentation type, freedom-seeking type, material oriented type, and practice-seeking type.

Purpose: The aim of this study was to identify the factors related with the intention of smoking abstinence among elementary students in a metropolitan city in Korea. Methods: All the elementary schools in the city were stratified by region, and then schools as a primary sampling units (PSU) were selected by probability proportional to size (PPS) sampling. One class per grade was sampled randomly from 5th and 6th grade in the sampled schools from October to December in 2004. The students completed a standardized self-administered questionnaire anonymously. A total number of 1,712 respondents who did not smoke was included in the final analysis. The dependent variable was an intention of smoking in the future, and it was dichotomized into 'absolutely confident in smoking abstinence' and 'others'. The risk of non-absolute confidence in smoking abstinence was calculated with simple and multiple logistic regression, which were conducted with STATA 9.0 by a design-based analysis considering strata variable, PSU, and sampling weight. Results: In the final model of multiple logistic regression analysis, those who were more likely to have non-absolute confidence in smoking abstinence were male students (OR=2.66, p<0.001); barely attending religious services (OR=3.32, p=0.002) or having no religion (OR=1.95, p=0.027); exposure to environmental tobacco smoke outside home 1${\sim}$2 days per week (OR=1.60, p=0.013); having friends who smoked (OR=1.93, p=0.011); non-absolute confidence in refusing to smoke (OR=5.35, p<0.001); having relatively less negative attitude (OR=2.88, p<0.001), positive attitude (OR=2.35, p<0.001), and indifference (OR=4.05, p=0.034) toward peer smoking; not good relationship with mother (OR=1.52, p=0.016). Conclusion: The factors related with non-absolute confidence in smoking abstinence were coincided with those of smoking among children. The results of this study suggest the smoking prevention education should be applied to the children more actively, especially who are not confident in smoking abstinence in the future.

공중보건 일반의사들의 업무수행 정도와 진료, 예방 및 보건증진 사업 수행에 필요한 기본적인 수기의 수행능력을 평가하고 그들의 업무 수행능력을 향상시키기 위한 교육 개선 방안을 마련하기 위하여 1982년과 1983년에 배치된 공중보건 일반의사들 가운데 남부 4개도(경북, 경남, 전북, 전남)에서 출신학교별로 비슷한 비율로 120명을 무작위로 뽑아 1984년 1월 9일에서 2월 10일 사이에 설문지를 이용한 집단면담을 하였다. 면담에 응한 97명 가운데 본 조사에 필요한 자료를 제시할 수 있었는 86명으로 부터 얻은 자료를 분석하였다. 보건지소의 진료실적은 2종 보험실시 지역이 1일 평균 $30{\sim}40$명으로 환자가 많으나 그외 지역은 $3{\sim}4$명으로 매우 저조하였다. 또한 예방 및 보건증진사업을 적극적으로 추진한다고 답한 사람은 조사대상자의 2%에 불과했다. 63가지 기본적인 임상수기 가운데서 자신있게 할 수 있다고 한 사람이 50%이상인 것은 근육주사, 정맥주사, 외상치료와 같이 간단한 것으로 12가지에 불과했고 임산부관리, 응급환자처치, 예방 및 보건증진 사업등에 필요한 수기에 자신이 있는 사람은 10%도 못 되었다. 국립보건원에서 실시하고 있는 공중보건 일반의사들의 실무교육이 현지 사정과 맞지 않는것이 많아 실무에 큰 도움이 안 된다고 했으며, 도립병원이나 지방 종합병원에서 받은 임상수련이 실무에 많은 도움이 된다고 한 사람은 38.8%였으며, 별도움이 안된 이유 가운데 전문의가 없거나 있어도 무관심하여 수련지도가 부족한 탓이라고 한 사람이 48.4%로 가장 많았다. 공중보건일반의 실무교육은 교육내용을 실무종사자들의 의견을 수렴하여 현지 사정에 맞도록 개선해야할 것이며, 실무종사자들 가운데 유능한 사람을 강사로 활용하고, 국립보건원에 모아 교육시키는 것보다 전국을 몇개의 지역으로 나누어 지방에서 교육을 시키는것이 효과적일 것이다. 임상실습은 4개월이 적당할 것으로 생각되며, 수련기간 동안에 필수적으로 익혀야 할 수기를 수첩으로 만들어 실습사실을 지도전문의에게 확인 받게하며, 보건사회부에서는 수련지도에 관한 지침을 마련하여 수련병원에 배부하고 수련상황을 평가하도록 한다. 최소한 기본 4과에 전문의를 갖춘 병원을 수련병원으로 선정하여야 할 것이다. 공중보건 일반의사들이 현지에서 당면하는 문제해결을 도우고 사업추진을 위한 동기를 유발하기 위해 보수교육이 필요하며 이를 위해 보건사회부는 재정 및 행정적 지원을 하는 것이 좋겠다. 도를 몇개지역으로 나누어 지역마다 지도위원회를 구성하여 공중보건 일반의사들을 순회지도 하고 자문에 응하도록 하는 것이 좋을 것으로 생각된다.
