Volatile Organic Compounds in Ambient Air at Four Residential Locations in Seoul, Korea.

To investigate the environmental behavior of volatile organic compounds (VOCs) in urban areas, their concentrations were measured at four urban monitoring sites (namely, N, S, E, and W) in Seoul, Korea (February to December 2009). A total of 27 compounds were quantified that consist of four chemical groups: aromatic (AR), halogenated aromatic, halogenated paraffin, and halogenated olefin. Results were evaluated by focusing on these four functional groups just mentioned and their summation term as total VOC (TVOC) along with several individual species (mainly AR species, that is, benzene, toluene, ethylbenzene, and xylene).

1-(2-Hy-droxy-2-phenyl-eth-yl)-3-(4-meth-oxy-phen-yl)urea.

In the title compound, C(16)H(18)N(2)O(3), the dihedral angle between the 4-meth-oxy-phenyl ring and the urea group is 35.6 (2) °. The H atoms of the urea NH groups are positioned syn to each other.

[Certificate education for geriatric physician: satisfaction and feasibility].

Objectives: Korea faces a number of challenges to meet demands in the area of geriatric professional medicine in a country with a rapidly ageing population. We evaluated the satisfaction and feasibility of the current education certification for geriatric physicians.

Methods: Geriatric physicians who were deemed qualified by the Korean Geriatrics Society during the period of 2001 to 2005 (n=2,200) were asked to complete structured questionnaires sent to them by mail about their satisfaction of and need for certificates of education, as well as their opinions on their geriatric specialty training.
