New limits are presented on the cross section for weakly interacting massive particle (WIMP) nucleon scattering in KIMS $\mathrm{CsI}(\mathrm{T}\ensuremath{\ell})$ detector array at Yangyang Underground Laboratory. The exposure used these results is $24\text{ }524.3\text{ }\text{ }\mathrm{kg}\ifmmode\cdot\else\textperiodcentered\fi{}\mathrm{days}$. Nuclei recoiling from WIMP interactions identified by a pulse shape discrimination method. A low energy background due to alpha emitters crystal...

This study was conducted to evaluate the effects of foam dressing with human recombinant epidermal growth factor (rhEGF) on healing process in head and neck cancer patients who experience radiation-induced dermatitis (RID). Seven patients, including three oropharyngeal, two nasopharyngeal one each hypopharyngeal laryngeal carcinoma, underwent radiotherapy (RT) for at Asan Medical Center from March December 2008 were prospectively included this study. Patients showed severe RID (more than wet...

This paper presents new zero-voltage/zero-current-switching (ZVZCS) PWM DC-DC converters. The proposed soft-switching technique achieves ZVS and ZCS simultaneously at both turn-on turn-off of the main switch diode by using only one auxiliary switch. Also, this is suitable for not minority but also majority carrier semiconductor devices. circuit topologies placed out power path, therefore, there are no voltage/current stresses on diode. operating principle illustrated a detailed study with...

Background: Surveillance of healthcare-associated infection (HAI) is the basis prevention programs. However, manual review medical records a labor-intensive and time-consuming process. We evaluated diagnostic performance automated surveillance HAI using electronic screening algorithms. Methods: Between April June 2022, we conducted manually automatically algorithm on 75 units (general surgical wards ICUs) in 2,700-bed, tertiary-care hospital South Korea. Algorithms for were developed...

KIMS is a dark matter search experiment using low background CsI(TB) crystals at Yangyang Underground Laboratory in Korea. With total exposure of 3409 kg⋅d data, we set new limit on WIMP‐nucleon cross section. We achieved the most stringent spin‐dependent interaction for pure proton case. were able to exclude DAMA signal region both and spin‐independent WIMP mass greater than 20 GeV/c2. upgraded with 12 corresponding 104 kg accumulating data since Jan. 2008.
