김진희,한근식,이윤환,Kim, Jin-Hee,Han, Geun-Shik,Lee, Yun-Hwan 대한예방의학회 2004 예방의학회지 Vol.37 No.2

Objective : To examine the association between dietary factors and cognitive impairment in older Korean women living in the community. Methods : Wave 2 data, from the Suwon Longitudinal Aging Study (SLAS), of 365 women aged 65 years or over, were used. The Korean version of the 30-point Mini-Mental State Examination (MMSE-K) was used to assess cognitive impairment (score$\geq$19). Dietary habits and frequencies of food group consumption were also examined. Results : A total of 67 women (18.4%) were found to be cognitively impaired. In bivariate analyses, nondietary factors, such as age, marital status, education, income, self-rated health, depression, emotional support, social activity, exercise, and dietary factors, such as self-rated nutritional status, frequency of beans and bean products and milk and dairy products consumption were associated with cognitive impairment. In the multivariate analysis, a higher frequency ($\geq$1 vs. <1 time/day) of beans and bean products (OR=0.48, 95% CI: 0.23-0.99) and milk and dairy products (OR=0.25, 95% CI: 0.10-0.61) consumption was inversely associated with cognitive impairment, after adjustment for non-dietary factors. Conclusion : These results suggest that dietary factors may play a significant role in cognitive impairment of older Korean women.

Objectives : To develop a physical functioning instrument for older adults living in the community. Methods : A representative sample of 979 people aged 65 years or over were interviewed in-person. Of these, 199 people also completed a detailed in-hospital examination. The scale items were selected based on the frequency of endorsement, along with the item-total and inter-item correlations. The associations of the scale with their physical performance and clinical examination were analyzed to evaluate the criterion-related validity. Construct validity was assessed using factor analysis, and internal consistency through Cronbach's alpha and item-total correlations. Test-retest reliability was measured by agreement between the household survey and the repeat survey at the in-hospital examination. Results : Initially, 23 items on the level of difficulty, ranging from no difficulty to an inability to complete a task, with the specific mobility and self-care tasks were included. Those with a high frequency of endorsement and a low inter-item or item-total correlations were excluded, resulting in a 10-item Physical Functioning (PT) scale. Equal weights were given to each item and a summated score was calculated. Significant associations were found between the PF scores and the physical performance, surrey and clinical data. The scale revealed a 2-factor (mobility and self-care) structure. Cronbach's alpha was 0.92 and the item-total correlations were in the 0.63 to 0.78 range. Pearson's correlations for the test-retest ranged between 0.56 and 0.61. Conclusions : The newly developed Physical Functioning (PF) scale showed good psychometric properties in older people. Further work, however, is needed to improve its sensitivity to discriminate higher levels of functioning, in addition to assessing its predictive value in detecting changes in health.

본 연구에서는 공장용지 면적을 예측하기 위한 통계적 추정을 다루었다. 공장용지에 대해서는 1981년부터 2003년까지 자료가 존재하며, 2004년 이후에는 공장용지보다 좁은 개념인 산업단지 면적에 대한 조사 자료만 존재한다. 한국산업단지공단에서는 2009년 10월 표본조사를 실시하여 당해의 공장용지 면적을 추정하였으며, 동 조사 시 향후 5개년의 공장용지면적에 대한 수요를 조사한 바 있다. 본 연구에서는 과거 절단된 자료를 여러 통계모형을 사용하여 적절히 대체할 수 있는 수요예측모형을 도출하고, 표본조사에 의한 추정치와 통계적 모형에 의한 대체값들을 융합하는 평활기법으로 향후 공장용지 수요를 예측하는 방법을 다루었다. In this paper, we have considered the problems of the estimation of the gross areas of a factory site relating to the areas of industrial complex lands based on a statistical forecasting model and the results of a sampling survey. In respect to the data of a gross areas of a factory site, we have only the sizes from 1981-2003. In 2009, the Korea Industrial Complex Corp. conducted a sampling survey to estimate its bulk size, and investigate the demands of its sizes for the next five years. In this study, we have adopted the sampling survey results, and have created a statistical growth model for the gross areas of a factory site to improve the prediction for the areas of a factory site. The three-different parts of data: the results of areas of a factory site by Korea National Statistical Office, imputation results by the statistical forecasting model, and sampling survey results have used as the basis for analysis. The combination of the three-different parts of data has created a new forecasting value of the areas of a factory site through the spline smoothing method.

It is very hard to estimate the number of total words in a language. Recently large corpus which is the body of written, spoken or other material and which is thought as the representative of a language is under construction. So, it is possible to estimate the number of words in a language based on the corpus. In this paper we propose the method for estimating the number of Korean words using Korean corpus and estimate the number of words. We also estimate the number of Korean names which occupy the large part of proper nouns. To estimate the number of total different Korean words and names we applied a generalized linear estimation method. 1,062,392 is the number of estimated Korean words using the corpus of 10 million phrases and 1,493,003 is the estimated number of Korean names.

인터넷산업 매출액 추정

민경현(Min, Kyung Hyun),한근식(Han Geun Shik) 한국IT서비스학회 2016 한국IT서비스학회 학술대회 논문집 Vol.2016 No.춘계

인터넷산업의 경제적 규모가 최근 들어 급격히 증가하고 있으며 이와 관련된 산업에의 영향도 커지고 있다. 이러한 인터넷산업의 급속한 변화와 발전은 인터넷 산업의 범위와 정의에 대한 질문에 이르게 된다. 이에 한국인터넷진흥원에서는 2009년과 2010년에 인터넷산업분류체계에 대한 연구를 진행하였으며 본 연구에서는 2010년 개발된 한국인터넷진흥원의 신인터넷산업분류에 당해연도 공표된 국가승인통계 중에서 필요한 분류 및 품목을 가공하여 인터넷산업의 매출액을 추정하였다. 일반적으로 통계생산 비용의 대부분은 조사비용에 할애된다. 그러나 현재 국내에서 생산되고 있는 다수의 ICT관련 국가승인통계를 기반으로 해당부문의 분류와 품목을 분석하여 인터넷산업의 매출을 가공생산 할 수 있다는 것을 보여주었으며, 인터넷산업의 급속한 변화를 반영한 인터넷산업분류의 부분적인 개편도 제안 하였다.

본 연구는 노인에서 치매 또는 우울증의 관련요인에 대하여 알아보기 위한 것으로 부천시 재가노인을 대상으로 설문조사를 실시하였다. 부천시 원미구에 거주하는 65세 이상 노인을 연령군과 성에 따라 이원층화 무작위 추출을 실시한 후, 최종응답자 1,015명을 대상으로 2000년 2월 23일부터 3월 31일까지 38일 동안 가구 방문하여 직접 면접 조사하였다. 치매와 우울에 대한 선별검사도구로는 Mini-Mental State Exam(MMSE-K)과 Center for Epidemiolgic Studies Depression Scale(CES-D)을 각각 사용하였다. 연구결과 조사대상자들은 치매(11.5%), 우울(13.3%), 치매ㆍ우울(5.2%), 정상(70.0%)의 분포를 보였다. 치매와 우울의 이환에 영향을 주는 요인들을 파악하기 위하여 정상군을 기준으로 다항분포 로지스틱 회귀분석을 실시한 결과, 고령이고 여성인 경우, 수입이 낮고, 도구적 일상생활 수행능력 장애가 많고, 자기 건강인식 수준이 나쁘며, 친구ㆍ이웃 만남이 적은 경우, 상대적으로 치매군의 비차비가 유의하게 높았다. 한편, 우울군에 있어서는 요통, 직업, 도구적 일상생활 수행능력 장애, 부정적 자기건강수준 인식이 유의한 관련이 있었다. 치매와 우울에 복합적으로 이환된 노인의 경우는 배우자가 없고 도구적 일상생활의 지장이 많으며, 요통이 있을 확률이 유의하게 높았다. 치매 또는 우울증 노인환자의 평가 및 관리에 있어 본 연구 결과 유의한 변수들을 고려할 필요가 있으며, 사회경제적으로 취약하고 신체기능이 저하된 노인환자들이 치매와 우울증과의 관련성이 높은 것으로 드러남에 따라 이에 대한 대책이 요망된다. The purpose of this study was to identify factors associated with dementia and depression among the community-dwelling elderly. This study was based on the survey of elderly residents of Buchon City that was conducted from February 23 to March 31, 2000. A total of 1,015 older persons responded to the in-person household interviews. We used the Mini-Mental State Examination, Korean version(MMSE-K) and the Center for the Epidemiologic Studies Depression Scale (CES-D) to assess the person's level of cognitive and depressive states. The respondents were identified as having dementia only (11.5%), depression only (13.3%), dementia and depression combined (5.2%), or none (70.0%). Multinomial logistic regression analyses were carried out, using those without any mental conditions as the reference category. Older age, females, low income, higher number of IADL limitations, poor self-rated health, rarely meeting friends were significantly associated with dementia. For depression, back pain, occupation, IADL disability, poor self-rated health were found to be significant factors. Having bark pain, not married, higher number of IADL disability were independently associated with comorbid mental conditions. It is important to consider diverse factors associated with depression and dementia among older adults to enhance and promote their mental health and well-being. The findings of low socioeconomic status and poor physical health being associated with mental health states, especially raise attention to the need for targeting these vulnerable segments within the older community.
