The physical and mechanical characteristics of 10 Indonesian wood species were investigated. Mangium, Gandaria and Rambutan showed higher density. Mangium, Gandaria and Mangga appeared lower in shrinkage, and the ratio of tangential/radial was low in Albizia, Kupa and Mangga. The compression strength parallel to the grain and hardness 김종호⋅장재혁⋅류재윤⋅Fauzi Febrianto⋅황원중⋅김남훈 -468 -were high in Mangium and Nangka. Gmelina, Mangium, Gandaria, Kupa, Nangka and Rambutan had valuable properties for commercial wood materials. Consequently, it is considered that the results of this study could be useful basic data for the improved use of planted and promising species in Indonesia.
Anatomical characteristics of White Jabon (Arthocephalus cadamba) and Red Jabon (Arthocephalus macrophyllus) were investigated by IAWA hardwood feature list. Both species were diffuse-porous, and radial multiple pore with 2∼3 rows was mostly observed. Tangential diameter of vessel lumina was 100 to 200 µm, and vessels per square millimeter were 5 to 20. White Jabon has more vessels than Red Jabon. The number of solitary pore per square millimeter in both species was similar, but more pore multiple was observed in White Jabon. Axial parenchyma diffuse was observed in both species, but axial parenchyma of White Jabon was hardly identified on the cross section. Rays were classified into "body ray cells procumbent with over 4 rows of upright/square marginal cells" type and partly "all ray cells upright and/or square" type on radial section. Ray width 1 to 3 cells and 1 to 2 cells observed in White Jabon and Red Jabon, respectively. Ray height of White Jabon was 420 µm and Red Jabon 474 µm. Fiber length was the range of 900 to 1,600 µm in both species, and it showed a tendency to increase from pith to bark. Consequently, it is considered that pore multiple, ray width and axial parenchyma are to be suggested the keys for identification of both species.
The study was carried out to investigate the characteristics of pellets manufactured with morphologically different Larix Kaemferi Carr sawdust. The pellet characteristics included mois-
Korean wood preservation standards require deep penetration, which precludes the use of many refractory species. However, such treatments of refractory species have been shown to be effective in other parts of the world. A field test was therefore initiated to evaluate the performance of western hemlock, a moderately refractory species, and white spruce, a highly refractory species, pressure treated with either copper azole or alkaline copper quaternary under Korean field conditions that included both decay and termite hazards. After 10 years of exposure in a ground proximity and field stake test in Jinju, Korea, the treated materials remained largely sound, while untreated controls failed much earlier, largely due to termite attack. These data suggest that material that does not meet current Korean penetration requirements could still provide effective protection against biodegradation under Korean conditions. Decay was more advanced in matched treated stakes exposed at a test site in Canada than at the site in Korea.
This study attempted to provide data and implications for establishing a competent care network system through implementing community-based integrated care policies by examining the network between the district office, the SOS care center, and social welfare institutions within the local community. The target area was S District in Seoul, and in all twenty-six general social welfare centers, institutions and organizations for the elderly and the disabled were analyzed for social networking among private institutions.
The structure and characteristics of the network between the district office and social welfare organization were examined through sociogram and centrality. The network between organizations carrying out integrated care in S District of the Seoul, was led by the local government, and the district office had a great influence. In addition, by confirming the role of the SOS care center as a central institution in the network in discovery and request of subjects, the basis for promoting an integrated care policy centered on local governments was presented. This study confirmed the importance of a public-private network in establishing a community-based advanced care service delivery system by revealing the characteristics of private central institutions participating in the network. Finally, this study proposed practical implications for the expansion and development of community-based integrated care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
