이 연구의 목적은 한국의 알츠하이머 질환 사망에 사회경제적인 요인이 어떻게 영향을 미치는지 파악하고 사망에서 사회적 불평등이 존재하는지를 분석하는 것이다. 이 연구는 한국의 사망통계 자료(통계청, 1995-2009년)과 인구센서스자료(통계청, 1995년, 2000년, 2005년)를 이용하여 65세 이상 노인의 사회경제적 상태가 알츠하이머 사망에 미치는 영향을 분석하였다. 사회경제적 상태 변수로 교육수준, 경제활동상태, 결혼상태를 선정했고, 종속변수로 65세 이상 노인의 알츠하이머 사망으로 정하여, 로지스틱 회귀분석을 실시했다. 연구 결과, 65세 이상 집단에서 남, 녀 모두 낮은 사회계급집단에서 알츠하이머질환 사망위험이 더 높았다. 특히 65-74세의 경우 초등학교 졸업 집단, 비경제활동집단에서, 결혼하지 않았거나 이혼, 사별 등으로 배우자가 없는 집단에서 알츠하이머 질환 사망위험이 더 높았다. 알츠하이머 사망 추이를 보면, 2000년-2004년 기간에 비해 2005년-2009기간에서 대학졸업집단과 초등학교 졸업 집단의 사망 격차가 커졌으며, 비경제 활동집단, 비결혼집단, 이혼 및 사별한 집단의 사망이 크게 증가했다. 이 연구는 65세-74세의 교육수준이 낮은 집단, 물질적 결핍 지수가 높은 집단, 그리고 배우자가 없는 집단에서 알츠하이머질환의 사회적 불평등이 크고, 불평등이 심화되는 경향을 보이고 있어, 국가적으로 65세이상 노인의 사회적불평등을 줄이는 정책이 필요하다는 것을 시사해주고 있다. This study examined the association between socioeconomic factors and Alzheimer s disease mortality and identified social inequality in the mortality among over 65 years old in Korea. Data were consisted of population census data in 1995, 2000, and 2005 and death registration data in 1995-2014 from the Korea National Statistical Office. The results showed that the death rate from Alzheimer s disease was increased in men aged 65-74 years with a high school diploma or less compared to those with a college diploma or more. The higher risk of mortality was found among those who are non-married, divorced, and widowed. So the mortality was higher for old adults living without spouse than for those living with spouse in adults over the age of 65. We found that the death rate from Alzheimer s disease was increased in adults aged 65-74 years with low education attainment, and that socioeconomic inequalities in mortality are apparent. Therefore, this study suggests that being physically active and building high social relationships will help old adults to reduce Alzheimer s disease prevalence and mortality. In addition, A public health policy for old adults living without spouse is necessary to improve social inequality in mortality from Alzheimer s disease.

Nowadays. the development of Microfluidic chip (i.e. Biochip. Micro-total analysis system (μ-TAS) and LOC (Lab on a Chip)) becomes more active. and the microchannels to deliver fluid by pressure or electroosmotic forces tend to be more complex like electronic circuits or networks. For a simple network of channels. we may calculate the pressure and the flow rate easily by using suitable formula. But for complex network, it is not handy to obtain those information with such a simple way. For this reason. Graphic User Interface program which can rapidly give required information should be necessary for microchip designers. In this paper, we present a GUI program named 'MFNS: Micro Fluidic Network System' developed in our laboratory including simple theoretical formula. We applied our program to simple case and could get a result compared well with other numerical result. Further. we applied our program to several complex cases and obtained reasonable results.

Perilla frutescens var. japonica Hara was collected from farmland in Seongju-gun. Fifteen endophytic fungal strains with different colony morphologies were isolated from roots of P. frutescens. Waito-c rice seedlings were treated with the concentrated culture filtrates (CF) of endophytic fungi for observation of their plant growth-promoting activities. In the results, the CF of Y2H001 fungal strain promoted the growth of the waito-c rice seedlings. The phylogenetic tree of Y2H001 strain was analyzed by the combined sequences of the partial internal transcribed spacer region (ITS) and partial betatubulin gene. Molecular and morphological studies identified the Y2H001 strain as belonging to Aspergillus flavus. In gas chromatography mass spectrometry (GC/MS) analysis of the CF of Y2H001 strain, gibberellic acid (GA) was detected and quantified. Therefore, we describe Y2H001 strain as a new GA3-producing A. flavus based on morphological, molecular characteristics and analysis of secondary metabolite.

This study was to intend to examine the effects of the online coaching program on the improvement of procrastination habit behaviors. The subjects of the study were adults living in the metropolitan area who wish to improve their procrastination habits. The final 20 people were selected through a pre-interview and randomly assigned 10 people to the experimental group and the control group, respectively. As dependent variables, procrastination behavior, general self-efficacy, self-regulation, and life satisfaction were measured before and after the program. A two-way mixed variance analysis (Mixed ANOVA) was conducted to analyze the interaction effects between time periods(pre vs post) and groups(experimental vs control). The results showed that there were no significant differences in the control group, but in the experimental group, the differences between pre- and post-tests for procrastination behavior, general self-efficacy, self-regulation, and life satisfaction were all statistically significant, confirming the effects of the online coaching program. Based on the results, the significance and limitations of this study were discussed.
