RESUMO

PURPOSE: This study tries to analyze the concept of Yangsaeng in the Korean aged, with focus on nursing. METHODS: Rodgers'evolutionary approach was used to identify the common definitions, attributes, antecedents, and consequences of the Yangsaeng concept for the aged. Literature search was conducted at the NAL, NDSL, RISS, ProQuest, PubMed, AMED, and MEDLINE databases from 2004 to 2016, using the keywords “Yangsaeng,” “health promotion,” “health management,” “traditional oriental methods,” and “traditional oriental nursing.”Finally, 20 relevant articles were selected and thoroughly reviewed. RESULTS: The analysis shows that the model of Yangsaeng for the Korean aged is that of personal adaptive-capacity, totality, challenging, and coping resource and includes physical, social and psychological health and wellness. CONCLUSION: This work provides some implications on the development of nursing intervention related with Yangsaeng for the Korean aged, and suggests the implementation of such intervention in the practice of Yangsaeng for the Korean aged. Therefore, a better understanding of the Korean aged and Yangsaeng within the context of nursing can be achieved.

RESUMO

We have studied the characteristics of longitudinal-optical-phonon-plasmon coupled (LOPC) mode by using the ultrashort pulsed laser with 45 THz bandwidth as a function of thickness in InAs epilayers, ranging from 10 to 900 nm. We have observed the LOPC modes split into the upper (L(+) mode) and the lower (L(-) mode) branches only in the classical scale, but the longitudinal-optical (LO) phonon peak was persistently observed. The shorter decay time of the plasmon-like L(+) modes rather than the phonon-like L(-) modes should be associated with carrier-carrier scattering which is further considered with diffusion properties in the low-gap semiconductors. This result leads to that the absence of the LOPC modes in a scale less than exciton Bohr radius manifests the role of electron diffusion rather than the carrier screening via drift motion in surface depletion region.
