Social Confluence Theory, as Applied to Cases of Disability Status and Korean Identity
Alex Lubet,김향은 한국학중앙연구원 한국학중앙연구원 2015 THE REVIEW OF KOREAN STUDIES Vol.18 No.2
This paper presents an exposition of social confluence theory, a concept of identity formation first introduced by Alex Lubet. The theory posits that the fundamental unit of identity in globalized, high technology, information-oriented societies such as the United States and South Korea is no longer a relatively stable unit such as the nation-state, ethnic group, faith community, nuclear or extended family, or individual. Rather, it is the status of the individual or group within the sociocultural or psychosocial encounter of the moment, which we call the social confluence. We first demonstrate the application of the theory with examples from the intersection of disability and music. To further illustrate the theory’s potential, we apply it to Korean identity, demonstrating the great mutability of that identity across different contexts or social confluences, using examples from South Korea and the United States, including international Korean adoptees, North Korean refugees, and Korean and other Asian-Americans in pan-Asian arts organizations. We conclude by proposing research topics in disability studies and Korean studies for which social confluence theory seems particularly apt, in particular the categorizations of people with Autistic Spectrum Conditions, while proposing extended research applications for the theory, with particular attention toward South Korea.
A new approach to design of RF energy harvesting system to enslave wireless sensor networks
Alex Mouapi,Nadir Hakem,Gilles Y. Delisle 한국통신학회 2018 ICT Express Vol.4 No.4
In trying to reach the goal of controlling the environment, recent years have seen the rapid emergence of Wireless Sensors Networks (WSN). Nevertheless, the lifetime of sensor nodes shows a strong dependence on battery capacity. Recently energy harvesting techniques have been considered to allow the use of WSN in the ”deploy and forget” mode. This paper proposes an assessment of the performance of a WSN enslaved to an optimized Radiofrequency Energy Harvesting System (REHS). The energy budget of a sensor node in a Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol is quantified and used to evaluate the performance of the WSN.

This study evaluated the species composition, diversity and phorophyte preference of epiphytes at the University of Port Harcourt located in southern part of Nigeria. Purposive sampling technique was used to select sites representing major avenues in the three campuses (Abuja, Choba and Delta) of the University. Data were collected on species name of phorophytes, number of individuals, diameter at breast height (dbh) and height, and species/number of epiphytes present on them. The points/sections of attachment of epiphytes on phorophytes were also recorded. A total of eight species of epiphyte belonging to six families were recorded in the study. Species diversity was higher in Abuja campus (Simpson 1-D=0.81; Shannon H=1.79), followed by Choba campus (Simpson 1-D=0.73; Shannon H=1.09) and Delta campus (Simpson 1-D=0.56; Shannon H=0.93). Species richness was highest in Abuja campus (n=8) followed by Delta campus (n=4) and Choba campus (n=3). Similarity in epiphyte species composition was highest between Choba and Delta campuses (85.71%), followed by Delta and Abuja campuses (66.67%) and lowest between Choba and Abuja campuses (54.55%). The family-Polypodiaceae, had the highest number of species (n=3). Microgramma owariensis had the highest relative abundance (27%) followed by Platycerium bifurcatum (26%) while Tillandsia utriculata and Peperomia pellucida had the least relative abundance (3%). Epiphyte abundance was weakly correlated with both the dbh and height of phorophytes. However, epiphytes were more abundant on phorophytes with rough/scaly/corky/flaky barks than on those with smooth barks. The planting of avenue tree species with rough barks is recommended to enhance the diversity of epiphytes in the study area.
Management of Malignancies Developing in AYA

Adolescent and young adult (AYA) with cancers have distinct spectrum of cancers as compared to younger and older age groups. The definition of age limits of AYA varies among countries, from 15-25 years to 12-39 years. The differences in age definition lead to variation in report of incidence, types of cancers and survival. In younger AYA patients, hematological malignancies are leading cause of cancers. In older AYA patients, testicular cancers are common in males while breast cancers and cervical cancers are predominant types in females. There is increasing incidence of AYA cancers worldwide in the past two decades. Overall survival and treatment outcome of AYA cancer has been improving in the last few decades. Specialized centers for AYA with cancers provide more comprehensive care and have been reported to have superior outcome. About 80% of AYA with cancers survive at 5 years after diagnosis but they are higher risk of developing second malignancies. Barriers to AYA cancer treatment included social economic status, insurance system and accessibility to clinical trials. Survivors of AYA cancers are also at higher risk dying from cardiovascular diseases and respiratory diseases. Survivorship program should be in place to enhance education and surveillance.
Effect of a through-building gap on wind-induced loading and dynamic responses of a tall building
Alex P. To,K.M. Lam,S.Y. Wong,Z.N. Xie 한국풍공학회 2012 Wind and Structures, An International Journal (WAS Vol.15 No.6
Many tall buildings possess through-building gaps at middle levels of the building elevation. Some of these floors are used as sky gardens, or refuge floors, through which wind can flow with limited blockage. It has been reported in the literature that through-building gaps can be effective in reducing across-wind excitation of tall buildings. This paper systematically examines the effectiveness of two configurations of a through-building gap, at the mid-height of a tall building, in reducing the windinduced dynamic responses of the building. The two configurations differ in the pattern of throughbuilding opening on the gap floor, one with opening through the central portion of the floor and the other with opening on the perimeter of the floor around a central core. Wind forces and moments on the building models were measured with a high-frequency force balance from which dynamic building responses were computed. The results show that both configurations of a through-building gap are effective in reducing the across-wind excitation with the one with opening around the perimeter of the floor being significantly more effective. Wind pressures were measured on the building faces with electronic pressure scanners to help understand the generation of wind excitation loading. The data suggest that the through-building gap reduces the fluctuating across-wind forces through a disturbance of the coherence and phase-alignment of vortex excitation.

Lipid droplets consist of a core of neutral lipids surrounded by a phospholipid monolayer with bound proteins. Much of the information on lipid droplet function comes from proteomic and lipodomic studies that identify the components of droplets isolated from organisms throughout the phylogenetic tree. Here, we add to that important inventory by reporting lipid droplet factors from the fission yeast, Schizosaccharomyces pombe. Unique to this study was the fact that cells were cultured in three different environments: 1) late log growth phase in glucose-based media, 2) stationary phase in glucosebased media, and 3) late log growth phase in media containing oleic acid. We confirmed colocalization of major factors with lipid droplets using live-cell fluorescent microscopy. We also analyzed droplets from each of the three conditions for sterol ester (SE) and triacylglycerol (TAG) content, along with their respective fatty acid compositions. We identified a previously undiscovered lipid droplet protein, Vip1p, which affects droplet size distribution. The results provide further insight into the workings of these ubiquitous organelles.
