In recent years the development of high-speed metropolitan networks has exploded, more and more households have access to such a network. In the case of IPTV there exits a need for an efficient way of transporting digital video over an Internet like network in a broadcast fashion. IP multicast is proven way to efficiently transmit multimedia content to a selected set of receiver. An IPTV stream consists of video, audio, and additional information. In this paper we present the method of improving the session protocol and The HGW(home gateway)'s buffer scheduling strategy for an apartment authenticate the highest FTTH class in EPON system.

In generally, water quality of eutrophic zone in lake must decrease nutrients for example phosphorous and nitrogen. This paper is concerned with limnological survey and several field experiment were done for estimating the effect of artificial circulation. Internal nitrogen loading was estimated by the loaboratiory corer method. Sedimentation of nitrogen and suspended solid were determined using sediment traps at bottom. NH₄-N release concentrations of surface on bottom were large more than removed sediment from 5mm to 20mm, However, after cover oxidized sedimentation by artificial circulation decreased NH₄-N release concentration, and nutrients concentrations of interstitical water in sediment were the reverse of the change NH₄-N release concentration by nitrification. TIN release fluxes from sediment lowered from 15.3㎎/㎡/day by 10.7㎎/㎡/day by artificial circulation in Masuma lake.

Objectives: The purpose of this study was to develop evidence-based recommendations on public drinking restriction in alcohol accessibility policies in order to bring about changes in the alcohol consumption norm. Methods: Nationwide cross-sectional data collected in 2018 was used. A total of 3,015 subjects (1,546 men and 1,469 women) aged 19 to 60 years were included in this study. Data were analyzed using SPSS, version 25.0. The association between drinking alcohol in public places and its harmful effects was analyzed in monthly drinkers. Results: About 71.2% of participants (73.6% men and 67.6% women) had drunk alcohol in public places. Unmarried men in their twenties who had full-time jobs were more likely to drink alcohol in public places (leisure facilities or spaces). Individuals who had experience drinking alcohol in public places drank more frequently and consumed a significantly larger quantity of alcohol. Drinking alcohol in public places was associated with higher risks of alcohol-related harm. Conclusions: The results of this study provide evidence-based data on public drinking restriction to minimize harm due to alcohol consumption.

This study aimed to verify the effect involving the improvement in quality of life, applying a music therapy to chronic hemiparetic patients due to a stroke. The subjects of our study were 25 stroke hemiparetic patients being registered with N Day Welfare Center located in Nowon-gu, from March 21st to September 21st, 2007, and we classified them into music therapy group with 13 patients and control group with 12 patients. Then we carried out a music therapy and physical therapy side by side in music therapy group for 6 months, and only physical therapy in control group for 6 months. In this study, with a result that we compared the total scores of general quality of life in stroke hemiparetic patients, the quality of life in music therapy group which has been placed under a music therapy and physical therapy side by side, appeared to made progress meaningfully, in comparison with control group which has been placed under only physical therapy (p<0.01). As the result shows that a music therapy generally improves mental and physical function of a stroke hemiparetic patient, and finally has an effect on the improvement in quality of life, it will be applied as a useful rehabilitation therapy mediation in the clinic field. 본 연구는 뇌졸중으로 인한 만성 편마비 환자의 삶의 질 향상을 위해 음악치료를 적용하여 그 효과를 검증하고 이를 토대로 향후 음악치료 프로그램이 편마비 노인들의 삶의 질 향상을 위한 기초 자료를 마련하기 위해서 시도되었다. 연구대상은 2007년 3월21일부터 9월21일까지 서울시 N복지관에 등록되어있는 뇌졸중 편마비 환자 25명을 실험집단 13명과 통제집단 12명으로 분류하여 실험집단은 6개월 동안 음악치료와 물리치료를 병행하여 실시하였고, 통제집단은 6개월 동안 물리치료만 실시하였다. 연구결과, 전체적인 삶의 질 총 점수는 물리치료만 실시한 통제집단에 비해 음악치료와 물리치료를 함께 실시한 실험집단에서 삶의 질이 유의하게 향상된 것으로 나타났다(p<0.01). 이와 같은 결과는 6개월 동안 실시한 음악치료가 전반적으로 뇌졸중 편마비 노인들의 정신적, 신체적인 기능을 향상시켜서 결과적으로 그들의 삶의 질을 높이는데 효과적이라고 할 수 있으므로 임상현장에서 유용한 재활치료 중재로 활용될 수 있을 것으로 사료된다.
