Improvement in Growth in Adolescents with Average Height Using A Massage Chair: A Prospective Single Arm Pre-Post and National Standard Data Comparison Study

Background: This study aimed to examine the changes in height, weight, and bone age between pre- and post-intervention when using a BEG-100 massage chair daily.Methods: Thirty-five children aged 11 years who were close to the average height (145-155 cm) were included in the study. There were 34 participants who used the BEG-100 massage chair for 24 weeks. Daily intervention consisted of 20 minutes of lower body massage and 10 minutes of whole-body massage. Height, weight, and adverse events were checked every five visits, while a hand X-ray was used before and after massages. The height percentile and height standard deviation score (SDS) were calculated using the 2017 Korean growth chart. The bone age and predicted adult height using radiographs were computed using the Tanner-Whitehouse method. The paired t-test or Wilcoxon signed-rank test was used according to normality of data to determine statistical significance.Results: A total of 31 children were included in the final analysis. The height percentile and height SDS significantly increased after BEG-100 massage chair use (2.39; <i>p</i> = 0.032, and 0.07; <i>p</i> = 0.036, respectively). However, these changes were not significant in children whose baseline height was shorter than the average. There were no significant differences in bone age, height for bone age, predicted adult height, or sitting height/height ratio. None of the participants complained of adverse events.Conclusion: The height percentile and SDS of teenagers increased after use of massage chair therefore, it is necessary to perform larger randomized controlled clinical studies.

965 INTEGRATED CARE HOME OWNERSHIP AND FINANCIAL VULNERABILITY

Abstract Introduction Lack of home ownership is associated higher rates of mental and physical ill-health and death1. According to longitudinal data in Ireland, 92% of persons aged 75 and over own their homes outright with approximately 8% living in rented accommodation2. We sought to compare characteristics of a cohort of patients open to our Integrated Care for Older Persons (ICOP) team with this national Irish dataset. Method A convenience sample of 50 patients reviewed by the ICOP team in a University Teaching Hospital was analysed. Data was anonymised and stored via encrypted key. Analysis was performed using SPSS v.27. Results The average age was 82.5 (±8.1) with 70% women in the sample. There was a lower prevalence of home ownership in this group of patients than the national norm (66% vs 92%) ie 34% were living in rental accommodation, majority Local Authorities. Those living in Local Authority accommodation had lower overall time spent in full time education than those who owned their own home (9.3 ± 3.1 vs 11.5 ± 3.3 p = 0.013), they were more likely to require external assistance with finances (54.5% v 88.2% p = 0.026) and less likely to have a Will (63.6% vs 35.2% p = NS) or EPOA (33.3% vs 23.5% p = 0.053) established. There was no significant difference in age, CFS, MMSE, Waterlow or polypharmacy rates between these groups. Discussion This report highlights a divergence between community dwelling older adults referred to ICOP teams and national standard data. Targeted social work interventions should be operationalised to assist financially vulnerable older adults. 1: Marmot M, Geddes I, Bloomer E, Allen J, Goldblatt P.

Structural Embeddedness and Firms’ Impact on the Technology Standard Setting Process

The extant literatures often focus on the efficiency of standard committees to coordinate conflicts between members and how regulatory capture occurs, thus neglecting the impact of cooperation behaviour on the technology standard setting process. This paper aims to explore how structural embeddedness affects firms’ impact on the technology standard setting process. We construct a network with the national standard data in China's communications industry in 2000-2017. With 326 firms participating in the standard formulation as the research sample, we use the negative binomial regression method to explore the relationship between structural embeddedness of technology sponsors and the impacts on the technology standard setting process. We find that while there is an inverted U-shaped relationship between the number of direct collaborators and firms’ impacts on the technology standard setting process, the structural holes positively affect firms’ impacts on the technology standard setting process. The conclusions obtained from this paper have important managerial implications for firms participating the technology standard setting processes.

Pediatric emergency care capabilities of Indian Health Service emergency medical service agencies serving American Indians/Alaska Natives in rural and frontier areas

In the USA, the emergency medical services (EMS) system is vital for American Indians and Alaska Natives, who are disproportionately burdened by injuries and diseases and often live in rural areas geographically far from hospitals. In rural areas, where significant health disparities exist, EMS is often a primary source of healthcare providing a safety net for uninsured individuals or families who otherwise lack access to health-related services. EMS is frequently the first entry point for children and their families into the healthcare system. The Indian Health Service (IHS) supports the federally funded, tribally operated EMS agencies to help meet the affiliated American Indian and Alaska Natives' pre-hospital needs. While periodic assessments of state EMS agencies capabilities to care for children occur, it appears a systematic assessment of IHS EMS agencies in regards to children had not been previously conducted. A consensus process, involving stakeholders, was used to identify topic areas for a survey for assessing the pediatric capabilities of IHS EMS. The survey was sent to 75 of 88 IHS EMS agency contacts. Sixty-one agencies (81%) responded. Nine agencies (15%) did not have a medical director. Agencies without a medical director were less likely to report the availability of online (p=0.1) or offline (p<0.01) pediatric medical direction. Half (51%) of the agencies had a mass casualties plan; however, 29% reported responding to a mass casualty incident, involving a large number of pediatric patients, that overwhelmed their service. Most agencies were well integrated with their state EMS system with almost all (95%) collecting EMS patient care data and 47% using national standard data elements. In some areas, IHS EMS agencies did not have the infrastructure to treat pediatric patients during day-to-day operations as well as disasters. Similar to operational challenges faced by rural EMS agencies, the IHS agencies lacked a medical director, were unable to provide pediatric continuing education, and were overwhelmed during mass casualty incidents. Moreover, the overall ratio of IHS EMS to service population is almost double that for other EMS agencies. In other areas, agencies were well integrated with their state EMS system. One possible solution to increase capabilities to care for pediatric patients is combining and sharing of common resources including medical directors with their state EMS systems and authorities.

수질모델링 지원을 위한 GIS 기반 한국형 Reach File 설계

수질모델링에 필요한 다양한 입력데이터는 관련 정보의 확보방안 및 표준화가 되어 있지 않아 수질모델링 결과 및 수질분석에 많은 영향을 주고 있다. 이에 본 연구에서는 효율적인 수질 모델링을 위해 정확한 수리 수문 데이터를 기반으로 한 수질모델링의 기초자료 데이터베이스인 한국형 Reach File을 설계하였다. 한국형 Reach File은 동일한 수리학적 특색을 가지는 구간(Reach)에 대한위치정보 기반의 수리학 데이터베이스로써, 각 구간을 대표할 수있는 Reach 코드와 Catalog Unit, Segment, Marker Index의 위상정보를 갖고 있으며 하천명이나 하천코드와 같은 기존 코드와의 연계를 고려하여 설계되었다. 설계방안을 토대로 경기도 광주시의 경안천을 대상으로 시범 구축을 통하여 본 설계안을 검토한 결과, 수질모델링에 필요한 기초데이터를 하나의 기준으로 체계화하여 하천정보를 데이터베이스화하고 기 구축 데이터베이스와의 연계 및 활용방안도 마련할 수 있었다. 또한, 각 구간별로 정의된 Reach 코드를 이용하여 수질기초시설, 오염원데이터, 관리기관 등 기존 데이터베이스와 연계를 통해 보다 체계적인 수질의 관리가 가능함을 알 수 있었다. 향후 연구에서는 Reach 코드를 하천공간데이터의 국가표준데이터로 선정할 수 있도록 하천 정보 표준화에 관한 연구가 필요하며, 전국 모든 하천에 Reach 코드를 부여하여 보다 많은 데이터베이스와의 연계할 수 있는 방안을 마련해야 할 것이다. Various input data required for water quality modeling have considerable impacts on modeling results and relevant analysis due to the absence of data standardization and lack of data accuracy. With this in mind, this study mainly focused on the designing Korean Reach File for more effective water quality modeling through the supply of database composed with accurate hydraulic and hydrologic data. The Korean Reach File is the hydraulic database with the locational information of individual reaches, and each reach represents the stream reach of homogeneous hydraulic characteristics. In detail, it has reach code designating each stream reach, and topological information including catalog unit, segment, marker and index. It was also designed considering linkage of existing codes such as stream name and stream code. The devised reach code was implemented to Kyungan River at the City of Gwangju of Kyunggi Province and the results showed that the reach code could effectively support the input database integrating basic numerous data required for water quality modeling based on a criterion as well as easier linkage and utilization with existing database. In addition, more systematic water quality management was enabled through the linkage of existing data such as treatment facilities, pollutant data, and management institutes using the reach codes defined for each stream section. In the future, more efforts need to be made to adopt the reach code as the national standard data thereby enabling utilization of numerous relevant database through the assigning of reach code to individual stream reaches nationwide.

Phenolic Molding Compound Filled with Nonmetals of Waste PCBs

Nonmetals reclaimed from waste phenolic cellulose paper printed circuit boards (PCBs) are used to replace wood flour in the production of phenolic molding compound (PMC). The results indicate that filling of nonmetals in PMC improves the charpy notched impact strength and heat deflection temperature (HDT) and reduces flexural strength and rasching fluidity. Rasching fluidity decreases dramatically with the increase of the content of nonmetals. To ensure sufficient properties of PMC, the optimal added content of nonmetals is 20 wt %, which results in a flexural strength of 70 MPa, a charpy notched impact strength of 2.4 KJ/m2, a HDT of 168 degrees C, a dielectric strength of 3.9 MV/m, and a rasching fluidity of 103 mm, all of which meet the national standard data. When the added content of nonmetals is 20%, the charpy notched impact strength, HDT, and rasching fluidity of PMC decrease, and the flexural and dielectric strengths decrease at first and then increase with decreasing particle sizes. All the results indicate that making PMC with nonmetals of waste PCBs can resolve environmental pollution, reuse nonmetals in different fields, and provide a new method for resource utilization of nonmetals from waste PCBs.
