Tuberculosis Notification Completeness and Timeliness in the Republic of Korea During 2012-2014.

Objectives: Completeness and timeliness are key attributes of accurate disease surveillance. This study aimed to evaluate the completeness and timeliness of tuberculosis (TB) notification in the Republic of Korea, by comparing notification data from the Korean National Tuberculosis Surveillance System and reimbursement data from the National Health Insurance.

Methods: We evaluated reimbursement data from 103,075 cases (2012-2014) and surveillance data from 215,055 cases (2011-2015); cases were matched using Resident Registration Numbers.

Synthesis of TiO2 nanorod-decorated graphene sheets and their highly efficient photocatalytic activities under visible-light irradiation.

The titanium dioxide (TiO(2)) nanorod-decorated graphene sheets photocatalysts with different TiO(2) nanorods population have been synthesized by a simple non-hydrolytic sol-gel approach. Electron microscopy and X-ray diffraction analysis indicated that the TiO(2) nanorods are well-dispersed and successfully anchored on the graphene sheet surface through the formation of covalent bonds between Ti and C atoms. The photocatalytic activities are evaluated in terms of the efficiencies of photodecomposition and adsorption of methylene blue (MB) in aqueous solution under visible-light irradiation.

Aqueous synthesis of silver nanoparticle embedded cationic polymer nanofibers and their antibacterial activity.

This paper describes the one-pot, aqueous synthesis of cationic polymer nanofibers with embedded silver nanoparticles. Poly[2-(tert-butylaminoethyl) methacrylate] (PTBAM) was used as a cationic polymer substrate to reinforce the antimicrobial activity of the embedded silver nanoparticles. Electron microscope analyses revealed that the as-synthesized nanofibers had diameters of approximately 40 nm and lengths up to about 10 μm.

A strategy for fabricating single layer graphene sheets based on a layer-by-layer self-assembly.

A novel approach to synthesize graphene nanosheet is explored on the basis of the layer-by-layer (LbL) self-assembly of polyallylamine (PAA) and poly(styrene-sulfonate) (PSS) multi-layer with a metallic dopant.

[Health pattern of elderly according to age group who living alone in an urban area].

Purpose: This study was conducted to identify the differences of health patterns; health-related characteristics, health behaviors, health problems, and self-care levels of elderly, living alone in an urban area according to age group.

Method: The study design was a descriptive survey and the subjects were 1,800 elderly consisting of 937 young old, 704 middle old, and 159 old old. Data was collected from May to July 2003 using the structured questionnaire and analyzed by descriptive statistics, chi(2)-test, Fisher's exact probability test, ANOVA and Scheffe test using SPSS/PC.

[Comparison of nursing activities reflected in nursing notes and in-depth interviews of nurses in an acute hospital].

Purpose: The purpose of this study was to compare the nursing activities delineated by interview of nurses with those on nursing notes.

Method: The participants of interview were 18 nurses working in medical and surgical units of a large hospital in Seoul. Each nurse was asked to choose one patient who demand most nursing care among her patients.

[Nurses' image perceived by academic and vocational high school teachers in Korea].

Purpose: The purpose of this study was to identify nurses' image and its related factors to make nurses' image among academic and vocational high school teachers in Korea.

Method: Study samples were composed of 470 teachers who were from 12 high schools in G and J city located in southwestern part of Korea. Data were collected from August 26 to October 4, 2002.
