A higher frequency of family meals is associated with good dietary habits in young people. This study focused on the relationships meal food neophobia and personality traits adolescents.For this purpose, we administered a survey to 495 middle school students Seoul metropolitan city, after which data were analyzed using SPSS (18.0) program. Pearson correlation was used determine among habits, traits, according meals.Dietary all showed significant differences meals. Further, eating regular (P...
The "Lomonosov" space project is lead by Lomonosov Moscow State University in collaboration with the following key partners: Joint Institute for Nuclear Research, Russia, of California, Los Angeles (USA), Pueblo (Mexico), Sungkyunkwan (Republic Korea) and Russian industry organizations to study some extreme phenomena related astrophysics, astroparticle physics, biology. primary goals this experiment are study: This paper directed towards general description both scientific equipment on board...
Abstract This paper presents data on the simultaneous and complementary observations of gamma-ray burst (GRB) GRB 161017A for optical, X-ray, gamma wavelengths obtained by Russian multi-messenger Lomonosov space observatory supplemented additional from Swift satellite as well ground-based MASTER Global Robotic Net 10 m Gran Telescopio Canarias. Multifrequency spectra this very powerful explosion indicate that it originated at a distance billion light years Earth. Here, we present results...
The study of GRB prompt emissions (PE) is one the main goals Lomonosov space mission. payloads monitor (BDRG) with wide-field optical cameras (SHOK) and ultra-fast flash observatory (UFFO) onboard satellite are intended for observation GRBs, in particular, their emissions. BDRG gamma-ray spectrometer designed to obtain temporal spectral information GRBs energy range 10–3000 keV as well provide triggers on several time scales (10 ms, 1 s 20 s) ground telescopes, including UFFO SHOK....
The Ultra-Fast Flash Observatory (UFFO) Burst Alert and Trigger Telescope (UBAT) has been designed built for the localization of transient X-ray sources such as Gamma Ray Bursts (GRBs). As one main instruments in UFFO payload onboard Lomonosov satellite (hereafter UFFO/Lomonosov), UBAT's roles are to monitor sky, rapidly locate track sources, trigger slewing a UV/optical telescope, namely Slewing Mirror (SMT). SMT, pioneering application rapid mirror technology line sight parallel UBAT,...
The Slewing Mirror Telescope (SMT) was proposed for rapid response to prompt UV/optical photons from Gamma-Ray Bursts (GRBs). SMT is a key component of the Ultra-Fast Flash Observatory (UFFO)-pathfinder, which will be launched aboard Lomonosov spacecraft at end 2013. utilizes motorized mirror that slews rapidly forward its target within second after triggering by an X-ray coded mask camera, makes unnecessary reorientation entire spacecraft. Subsequent measurement accomplished 10 cm aperture...
The payload of the UFFO (Ultra-Fast Flash Observatory)-pathfinder now onboard Lomonosov spacecraft (hereafter UFFO/Lomonosov) is a dedicated instrument for observation GRBs. Its primary aim to capture rise phase optical light curve, one least known aspects Fast response measurements emission GRB will be made by Slewing Mirror Telescope (SMT), key payload, which open new frontier in transient studies probing early GRBs with time seconds first time. SMT employs rapidly slewing mirror redirect...
To observe the early optical emissions from gamma ray bursts (GRBs), we built Slew Mirror Telescope.It utilizes a 150 mm motorized mirror to redirect incoming photons astrophysical objects within seconds and track them as compensating satellite movements.The SMT is major component of UFFO-pathfinder payload, which was launched on April 28, 2016, onboard Lomonosov satellite.For first time, slewing system has been proven for precision tracking during space operation.We confirmed that 1.4...
인구 고령화 및 평균기대수명 연장과 더불어 만성질환자의 수가 크게 증가하였다. 고통스러운 불치병을 앓는 환자의 경우, 그에게 고통을 멈추고 '존엄한 죽음'을 선택할 권리가 있는지가 사회적 쟁점으로 부상하였다. 이 연구는 존엄사에 대한 사람들의 태도가 그들이 인지한 가족관계 만족과 대인신뢰에 따라 어떻게 차이가 있는지를 분석하였다. 자료는 성균관대학교 서베이리서치센터에서 실시한 2018년도 한국종합사회조사(Korean General Social Survey)를 활용하였으며, 총 853명을 대상으로 이항 로짓분석을 실시하였다. 분석은 주요 독립변수인 대인신뢰 외에도 배경변수인 성, 연령, 교육수준, 소득, 주관적 건강수준, 가구형태, 종교를 고려하였다. 배경변수만을 투입한 모형에서는 소득수준이 높은 사람일수록 동의할 가능성이 높았고, 불교나 개신교를 믿는 사람이 종교가 없는 사람에 비해 동의하지 않을 높았다. 배경변수를 통제한 후에도 변수는 태도와 유의한 관계가 있는 것으로...
Operating rooms (ORs) are healthcare areas that high-risk regarding patient safety (PS). The prevention of PS errors such as wrong-site surgery, medication errors, and falls is important in the OR. Causes having insufficient information, not taking enough care precautions, inattention may lead to errors. Ensuring an organization depends on composition a culture. This study, equivalent-control-group pretest-posttest research, aimed develop apply simulation-based education program for...

One of the unexplored domains in study gamma-ray bursts (GRBs) is early time phase optical light curve. We have proposed Ultra-Fast Flash Observatory (UFFO) to address this question through extraordinary opportunities presented by a series small space missions. The UFFO equipped with fast-response Slewing Mirror Telescope that uses rapidly moving mirror or array redirect beam rather than slewing entire spacecraft telescope aim instrument at GRB position. will probe rise GRBs sub-second...
Ultra-Fast Flash Observatory pathfinder(UFFO-p) was launched onboard Lomonosov on 28th of April, 2016, and now is under various types calibration for detection Gamma Ray Bursts (GRBs). Since last September UFFO-p has taken X-ray data in space with UFFO Burst Alert & Trigger telescope (UBAT), those X-rays are mostly diffused backgrounds however, the rate turns out to be higher than expected by a factor three. We assumed cosmic rays can contribute making count higher. did such simulation...
