Decision Factors in Purchasing Denim Jeans: Comparison of Teens and College Students

A pair of denim jeans is a daily fashion item that almost every teen and college-age individual owns and wears on a regular basis. The population of teens born between 1994 and 2010 is estimated to be more than 23 million and is the fastest growing segment in the apparel industry (Schrorer, 2012). Recent research (Setlow, 2000) has shown that apparel companies are targeting this growing population as they have large discretionary spending power

Insect Fauna of Mt. Jang-san, Yeongwol-gun, Gangwon-do, Korea

AbstractAn entomofauna study of Jangsan Mountain (1,408.8 m) in Yeongwol-gun, Gangwon-do was carried out from April to September, 2010. The distribution of 384 species, 91 families and 12 orders was confirmed from the study area

Refinement treatment of nasal bone fracture: A 6-year study of 329 patients

SummaryBackgroundThe reliability of X-ray radiography for diagnosing nasal bone fractures (NBFs) remains controversial. Recent studies show that, for determining the orientation and location of the displaced/depressed fracture, nasal sonography is as accurate as facial computed tomography. This retrospective study compared conductor-assisted nasal sonography (CANS) to conventional diagnostic tools and reported subjective patient satisfaction and discomfort after closed reduction combined with tube technique.MethodsThis retrospective study reports the results of 329 refinement treatments for nasal bone fracture (including 199 men and 130 women) performed from 2005 to 2011. All patients were assessed with CANS and completed a survey immediately prior to removing the packing. Questionnaires were adapted from the nasal obstruction symptom evaluation (NOSE) scale.ResultsThe study found that CANS has a 97.2% rate of accuracy in diagnosing NBF. The visual analog scale scores of nasal obstruction, nasal congestion, sleep disturbance, trouble breathing, and inability to move air through the nose were analyzed. The experimental group scores were significantly different from the control group for all scores (p < 0.001).ConclusionCompared to conventional methods, CANS is more accurate for detecting NBF. We recommend its use as an alternative tool for diagnosing a nasal fracture. Because the tube technique balances pressure between the nasopharynx and middle ear during swallowing, patient comfort is enhanced. Application of these modifications can improve accuracy in diagnosing NBF and can improve the quality of NBF treatment

Thin cell fringe-field-switching liquid crystal display with a chiral dopant

A fringe-field-switching (FFS) liquid crystal display (LCD) using a thin cell doped with a reverse-handed chiral compound is proposed. Such a FFS LCD exhibits a fast response time (similar to 8 ms), high transmittance ( \u3e 90%), low operating voltage (5 V(rms)), and intrinsically wide viewing angle. Its application for LCD televisions in order to reduce image blurring is emphasized. (C) 2008 American Institute of Physics

A facility for mass production of ultra-pure NaI powder for the COSINE-200 experiment

COSINE-200 is the next phase of the ongoing COSINE-100 experiment. The main purpose of the experiment is the performance of an unambiguous verification of the annual modulation signals observed by the DAMA experiment. The success of the experiment critically depends on the production of a 200 kg array of ultra-pure NaI(Tl) crystal detectors that have lower backgrounds than the DAMA crystals. The purification of raw powder is the initial but important step toward the production of ultra-pure NaI(Tl) detectors. We have already demonstrated that fractional recrystallization from water solutions is an effective method for the removal of the problematic K and Pb elements. For the mass production of purified powder, a clean facility for the fractional recrystallization had been constructed at the Institute for Basic Science (IBS), Korea. Here, we report the design of the purification process, material recovery, and performance of the NaI powder purification facility.Comment: Proceeding for INSTR20, accepted in JINS
