이상의 결과를 통하여 볼 때, 1년간의 규칙적인 운동은 남성 치매환자의 일상생활도 향상에 매우 효과적임을 알 수 있었고, TC, TC, LDL-C을 감소시키고 HDL-C을 증가시킴으로써 결과적으로 동맥경화와 심장병을 방지할 뿐만 아니라 독립적이고도 책임 있는 일상생활을 통해 치매환자의 삶의 질을 높이는데 큰 도움을 줄 것으로 기대된다. The purpose of this study was to investigate effects of regular exercise on ADL (activities of daily living) and lipid profiles (total cholesterol, triglyceride, HDL-C, LDL-C) in male patients with dementia. The subjects were consisted of 24 male patients with dementia, they were divided into two groups. the exercise group (EC, n=12) and the control group (CG, n=12). The exercise group participated in regular exercise program, and their ADL, lipid profiles levels were evaluated at baseline (pre, 0 mo), after 6 months (mid, 6 mo), and after 12 months (post, 12 mo). The subjects carried on exercising $30\∼60$ minutes a day, $2\∼3$ times per week for 12 months. Statistical techniques for data analysis was paired samples t-test. The level of statistical significance was $p\leq.0.5$. The results of this study were summarized as follows: In the case of EG, mid and post ADL values significantly higher than that of pre value, whereas there was no significant difference in the CG. Mid and post values of TC, TG, and LDL-C were significantly lower than that of pre value in the EG. However, mid and post HDL-C values were higher in the EG compared to pre value. In conclusion, these results suggest that regular exercise have an positive effect on ADL and lipid profiles in male patient with dementia. In addition, regular exercise may be helpful to reduce the incidence of heart disease and coronary sclerosis.
Paravalvular leaks (PVLs) often occur after surgical valve replacement. Surgical reoperation has been the gold standard of therapy forPVLs, but it carries a higher operative risk and an increased incidence of re-leaks compared to the initial surgery. In high surgical risk pa-tients with appropriate geometries, transcatheter closure of PVLs could be an alternative to redo-surgery. Here, we report a case of success-ful staged transcatheter closures of a fistula tract between the aorta and right atrium, and mitral PVLs after mitral valve replacement andtricuspid annuloplasty.
This study aims to find key factors that increase the important factor and the user satisfaction of the event information web-sites. The results of the collected data reveal that information quality, system quality, perceived usefulness, playfulness and community affect on the important factors of the event information web sites. However, community do not affect on the important factor of the event information web sites. This result shows that "community" which is an affecting factor in a commerce web site, are not interesting to user who access event information web sites. Moreover, they consider the quality of information more than community. Based on this research, we can see that the most important factor for the user satisfaction of the event information web site is the information quality. .

In this research, the fire mistaken dispatch records for the past 11 years have been analyzed by using a statistic technique. Fire mistaken dispatch occurred yearly average 48,371±5,763 time at 95 % confidence level. This is 1.2 times more than the dispatch for extinguishing the fire. Fire mistaken dispatch has been increased mainly by malfunctioning alarm among other various reasons and the reason of mistaken dispatch is different depending on the population of the region. In big cities, the burning smell accounts for the most of mistaken dispatch but in rural areas, the garbage incineration is the major reason for mistaken dispatch. As a result of calculating the mean time between fire mistaken dispatches (MTBFmd)by region, MTBFmd of Daejeon is 20.61 hr/time and its reliability is 95.26 % at t=1 hr. On the other hand, the MTBFmd of Gyeonggi is 0.58 hr/time and its reliability is 17.91 % at t=1 hr. 과거 11년간의 국내 화재 오인출동 자료를 통계적 기법을 활용하여 분석하였다. 오인출동은 95 % 신뢰수준에서 연평균 48,371±5,763건이 발생하였고, 이는 화재진압을 위한 출동보다 약 1.2배 높은 수준이다. 여러 원인 중 경보오동작에의한 오인출동이 증가하고 있으며, 오인출동의 원인은 시·도별 인구수에 따라 다른 양상을 보이는데 대도시에서는 타는 냄새에 의한 오인출동이 많은 반면 농어촌에서는 쓰레기 소각에 의한 오인출동이 많았다. 지역별 평균오인출동간격을계산한 결과 대전은 20.61 hr/회로 t=1 hr 일 때 95.26 %의 신뢰도를 보이는 반면, 경기도의 경우 평균오인출동간격은0.58 hr/회로 t=1 hr 일 때 신뢰도가 17.91 %에 불과하였다.

Combustion characteristics of outdoor advertisement materials were evaluated for fire risk assessment about fire expanding. At this study, the flame retardancy and the limiting oxygen index (LOI) was measured by UL 94 and ASTM D 2863 respectively. At the result of flame retardancy, foamex was V-0 grade and those of others were out of grade. LOI measurement showed that the LOI of foamex was highest in the samples. The cone calorimeter test was done by ISO 5660-1 to find the combustion characteristics. The cone calorimeter test showed that the outdoor advertisement materials were not good to prevent of fire expanding. The time to ignition (TTI) of flex was the fastest and the peak heat release rate (PHRR) as well as the total heat release (THR) of acrylic panel was higher than those of others. 상층 및 인접건물로의 연소확대 위험성이 있는 옥외 광고물 소재의 연소특성을 평가하였다. 본 연구에서는 UL 94와ASTM D 2863에 따라 난연성과 한계산소지수를 평가하였다. 난연성 평가결과, 포멕스가 V-0의 높은 난연성을 보이는반면 다른 시료들에서는 등급외의 난연성을 보였다. 한계산소지수 평가 결과에서도 포멕스의 한계산소지수가 가장 높았다. ISO 5660-1에 따라 콘칼로리미터를 이용하여 연소특성을 평가하였으며, 콘칼로리미터 시험결과 옥외 광고물 소재들은 화재확대 예방에 취약하다는 것을 알 수 있었다. 플렉스의 착화시간이 가장 빨랐으며, 특히 아크릴판은 최대 열방출율 뿐만 아니라 총 방출열량 또한 다른 소재들에 비해 높았다.
This study was performed to select single nucleotide polymorphisms (SNPs) related to the body burden of heavy metals in Koreans, to provide Korean allele frequencies of selected SNPs, and to assess the difference in allele frequencies with other ethnicities. The candidate-gene approach method and genome-wide association screening were used to select SNPs related to the body burden of heavy metals. Genotyping analysis of the final 192 SNPs selected was performed on 1,483 subjects using the VeraCode Goldengate assay. Allele frequencies differences and genetic differentiations between the Korean population and Chinese (CHB), Japanese (JPT), Caucasian (CEU), and African (YIR) populations were tested by Fisher’s exact test and fixation index (FST), respectively. The Korean population was genetically similar to the CHB and JPT populations (FST < 0.05, for all SNPs in both populations). However, a significant difference in the allele frequencies between the Korean and CEU and YIR populations were observed in 99 SNPs (60.7%) and 120 SNPs (73.6%), respectively. Ten (6.1%) and 26 (16.0%) SNPs had genetic differentiation (FST > 0.05) among the Korean-CEU and Korean-YIR comparisons, respectively. The SNP with the largest FST value between the Korean and African populations was cystathionine-β-synthase rs234709 (FST: KOR-YIR, 0.309; KOR-CEU, 0.064). Our study suggests that interethnic differences exist in SNPs associated with heavy metals of Koreans, and it should be considered in future studies that address ethnic differences in heavy-metal concentrations in the body and genetic susceptibility to the body burden of heavy metals.
