수중 센서 네트워크에서는 물 속이라는 환경적 특성으로 인해 네트워크 구성에 있어서 많은 어려움이 있다. 무엇보다도 배터리를 지속적으로 공급받거나 충전시킬 수 없기 때문에 배터리 고갈로 인한 센서노드의 손실이 발생하고 이는 전체 센서 네트워크 연결을 방해하는 요소로 작용하게 된다. 따라서 본 논문에서는 지역적으로 소스 라우팅 기법을 적용하여 에너지 소비를 줄이는 라우팅 기법을 제안하였다. 먼저 수중 통신에 사용되는 음파와 에너지와의 관계식을 유도한 뒤에 에너지 소비에 중요하게 작용하는 변수들을 이끌어 냈다. 깊은 바다에 설치된 센서 네트워크에서는 깊이에 따른 환경 변수들의 값이 달라질 수 있기 때문에 링크 메트릭에 영향을 줄 수 있음을 확인했고 이를 바탕으로 에너지 소비에 미치는 환경변수들의 영향도와 제안된 라우팅 기법이 에너지 소비에 미치는 영향을 시뮬레이션을 통해 확인하였다.

미디어 기술의 발전으로 스마트미디어의 대표적인 OTT서비스와 일인방송 규모가 급격히 확대되고 있다. 이로써 Z세대나 밀레니얼세대들은 더 이상 레가시미디어에 종속되지 않고 동기화, 개인화, 직관화, 실감화가 특성인 스마트미디어를 일상생활에서 향유하고 있다. 따라서 미디어 소비 행태도 급격히 변화하여 레가시 미디어인 지상파방송, 유료방송은 광고 매출, 콘텐츠 소비 등에서 디지털 인터넷 플랫폼과 경쟁에 어려움을 겪으며 성장에 어려움을 겪고 있다. 본 논문에서는 OTT와 일인방송이 중심이 되는 스마트미디어에서의 미디어 소비 행태의 변화를 알아보고 이에 따른 스마트미디어의 성장과 교육환경과의 상관성에 대해 고찰하고자 한다.

Although the concept of the elderly varies depending on scholars and laws, as consumption expenditure is deeply associated with income due to the nature of this study, 55 years old was set as the low limit standard for the elderly according to Prohibition of Discrimination on Age in Employment and Employment Promotion for the Aged Act and the elderly households were limited to single-elderly person household and an elderly couple family household for this study. It is considered consumption characteristics as a significant analysis subject in terms of social welfare because it could be understood as an expressed need which was a reflection of desire. Therefore, the present study aimed to investigate the consumption characteristics of the elderly households by stereotyping the consumption pattern of the elderly households, and find the determining factors for consumption patterns and thus contribute to the establishment of related policies through the expressed needs of the elderly households. K-means of cluster analysis was performed by putting the consumption expenditure of the elderly households to investigate inherent structural type of consumption pattern of the elderly households, which were the investigation subjects. As a result, four groups were stereotyped and named as below: 'health care-centered type', 'saving-centered type', 'livelihood-centered type', and 'food expenses-centered type' Binary Logistic Regression analysis was used to identify the factors that influence the decision of consumption pattern of the elderly households. The result of study showed that the elderly households faced all different needs and problems and thus there is a need for various approach plans to solve this situation. In particular, although the elderly have been viewed as economically poor people so far, the study showed that there were also kind of prepared households through saving. Overall, livelihoodcentered type accounted for the highest portion and, as a factor that influenced this, marital state and household income played an important role. Therefore, it is considered that more active efforts to increase the income of the elderly households are needed. In addition, age, owning of house and subjective health state were found to also have significant influence. Through these results of the study, the elderly's own improvement of awareness on health, presentation of overall standard for health state of the elderly, securement of the elderly's access to cultural life, and financial management coordination for improvement of quality of life, development and dissemination of jobs suitable for the elderly, and dissemination of communal life household, which is a cooperation residential type, were presented as institutional task in the conclusion.

This study is intended to explore an income level necessart for the old-age by income Status. Firstly, it is verified whether there is significant difference between old-age and working age or not. Secondly, if their difference is found, it will be identified that it is determined by certain factors. Thirdly, it is brought out needful income level for the old-age living through analysing old-age consumption expenditure level over working age. The results in this research are as follows. Firstly, there is a significant difference between old-age and working age. Secondly, the major factors which generated difference between old-age and working age consumption expenditure are income, household size, and age. Thirdly, the income level necessary for oldage living is on average 61 %. By income status, it is 90-100% for low income status, 60-70% for middle income status, 50-60% for high income status.

The purpose of this study is to critically interpret generational trends in contemporary Korea through understanding the consumer experiences of luxury bag purchases of women in their late 20s and early 30s. Previous studies on luxury consumption tend to focus on an analysis of the value of luxury products as a sign and a symbol, the characteristics or class identity of luxury consumers, or expressive behavior in terms of ideal self-image. While including these factors, this study also expands the scope to a reflexive understanding of the social structural context behind the phenomenon of personal consumption. This was achieved by considering consumption in terms of the style and practice of everyday life, as well as its opportunities and limitations. In particular, we pay attention to how luxury bags are reproduced as media, which is a process that is circulated back to consumption, and through this process, this study reflects on capitalist life and subjects.

This study was carried out to analyze the consumption expenditure condition of elderly persons with and without physical disabilities by social economic status and sociodemographic characteristics and to compare the results of those two groups for making an offer the basic materials to provide political support for elderly persons with physical disabilities. The statistical analysis of collected data was enforced through T-test, ANOVA and Crosstabs with SPSS 19.0 program. The results of this study are summarized as follows. First, the group with disabilities has presumed to be in relative poverty given that disposable income, academic career and total living expenses showed lower than the other group. Second, the component ratios of domestic foods and housing expenses of disabled group showed higher but those of specific spending items of expenditure such as social activities, reserving fund of social security for economic safety net, clothing and eating out expenses showed lower than the other group.

Lead isotope ratios in horse-shaped bronze buckles excavated from the Songjeol-dong site in Cheongju and the mid-western region of the Korean Peninsula have been determined by thermal ionization mass spectrometry. The lead isotope ratios of the samples with data provenance were plotted in zone 3 of the South Korean galena map. The results indicated that the horse-shaped bronze buckles could be made using galena located in the same area as the archaeological site. These results can be used as basic data for comparison purposes in future studies on the manufacturing technology and provenance of bronze artifacts.
