Purpose: The purpose of this study is to determine the different pattern of movement in children aged between 4-6 regarding to their motor development level. Twenty participants were selected and ranked into a high(n=9) or low(n=11) group based on MABC-2 score. Participants were asked to lie down on the mat and stand up on the signal “Go” as quickly as possible. Each trial repeated for ten times total. We analyzed body movement(upper extremity, axial region, lower extremity) pattern and measured total task time. As a result, there were significant differences in the movement time getting up from the supine posture and the movement pattern between high and low groups. Upper extremity (UE) show greater difference rather than the lower extremity (LE) and axial region (AX). The high ranked group used symmetrical movement pattern to get up, whereas most participants from the low group showed asymmetrical movement pattern. The high ranked group could perform more advanced level of movement pattern and took less time to get up overall. In addition, there was a positive correlation between the MABC-2 total score(%) and the movement patterns from UE, AX and LE regions. In conclusion, the STS task will be a useful tool to assess children motor development levels. Also, STS task can be usefully applied in education field.

A construction project is a complex process consisting of interdependent tasks. If one task has variation, other tasks will be affected additionally and it is difficult to reach consensus on task variation due to the characteristics of the construction site that is going on quickly and complicatedly. Therefore, this study identified the root cause of task variation in construction process. Adjacent matrix was created with the tasks corresponding to major causes of variation, and the network analysis was performed. The results of social network analysis in the construction process can stabilize the work flow in the complex process and improve the reliability of the process plan and the project performance.

In this study, experimental and analytical studies were conducted on the structural performance of permanent steel formed wide beams in construction stage. Four specimens were fabricated with different rib spacings of the side steel formwork and fixing plate depths, and experimental tests were performed to investigate the effects of variables on the structural performance. Also, an finite element analysis model of the steel permanent formwork wide beam was proposed based on the test results. Using the proposed model, parametric studies were performed with variables including rib spacing of the bottom and side steel formwork, spacing, depth, and thickness of the fixing plate to derive optimized details. Furthermore, an artificial neural network model was developed to easily estimate the deformation of the steel permanent formwork wide beam with various details.

The purpose of this study is to examine the changes in the audience’s participatory characteristics inSong Joo-won’s performance using virtual reality technology, 「20▲△」(2023), in response to theconcept of ‘emancipated spectator’ as mentioned by Jacques Rancière. As a result, on the unfamiliar and uncomfortable stage of ‘discord’ where dancers, audience,performance assistants, and different times and spaces coexist, a process of ‘re-division of senses’ wasdiscovered. In addition, a new way of sensory perception of appreciating work emerged, and theaudience was able to experience new ways of appreciating work. I was able to discover the form of‘free play’ that explores the work, recognizes its presence, and re-choreographs it. In this way, we were able to find the possibility of the emancipated spectator becoming an activeinterpreter, liberated through individual experience and intellectual adventure in a dance performanceusing VR.

The purpose of this study is to analyze the effects of the simulation-based professional cardiac resuscitation training on the performance of professional cardiac resuscitation performed by paramedics in the pre-hospital stage and to provide basic data for effective cardiac resuscitation. This study is an experimental study of the design before and after the control of non-equality. The subjects of this study were 16 newly recruited paramedics from K firefighting school. The simulation training program and evaluation papers used as the evaluation tool were reviewed and commented by 6 ACLS simulation experts (2 emergency medical doctor, 2 emergency medical professors, 2 KALS instructors)Respectively. The training consisted of 30 minutes of theory and 150 minutes of practical training. The lecturer first demonstrated for 5 minutes, and after training by individual debriefing after individual training, individual and team education was conductedThe evaluation scale was given a 5 - point Likert scale. The SPSS 22.0 program for Windows was used. The general characteristics of the subjects were analyzed for frequency, the examination of homogeneity between the experimental group and the control group wasfulfilled by t test, and the difference test between the groups of the two groups was performed using the paired t-test. The homogeneity test was able to confirm the homogeneity between experimental group and control group. In the evaluation of six ACLS techniques, it was proven that the experimental group that received the simulation training had better performance in all aspects than the non - training control group. The following are the technical items to be performed. 1. Electrocardiogram 2. Specialized instrument 3. Treatment of fluid 4. Leadership and teamwork 5. Medical guidance 6. Evaluation during transfer. It was proved that paramedics who received simulation training were improved on their job performance ability than general lecture and training group. Therefore, if simulation training and education are applied to a student in the synthetic course or an emergency resident who is engaged in clinical practice, he / she will be able to perform his / her duties more proficiently. It is expected that emergency services provided to patients with cardiac arrest will be improved. 본 연구는 시뮬레이션을 기반으로 한 전문심장소생술 교육이 병원 전 단계에 구급대원이 환자에게 시행하는 전문심장소생술 직무수행에 미치는 영향을 분석하고 효과적인 전문심장소생술을 시행하기 위한 기초자료를 제공하는데 그 목적이 있다. 비동등성 대조군 전후 설계를 기초하였으며 연구대상은 K소방학교의 신규 임용된 구급대원 16명이 참여하였다. 평가도구로 사용된 시뮬레이션 교육 프로그램과 평가지는 ACLS 시뮬레이션 전문가 6인(응급의학 전문의 2명, 전공교수 2명, 전문강사 2명)에게 사전 검토 및 의견을 받아 본 연구에 적합한 도구로 개발하였다. 교육은 이론 30분, 실습 150분으로 구성하여 4인 1조 1개팀으로 구성하였다. 강사가 5분간 시연을 한 후 개인별 실습 후 디브리핑(debriefing)을 통한 교정을 거친 후 개별, 팀별 교육을 실시하였다. 평가척도는 5점 리커트(Likert) 척도로 수행능력 평가 점수를 부여하였다. 자료분석은 Windows용 SPSS 22.0 프로그램을 사용하였으며, 대상자의 일반적 특성은 빈도분석을 하였으며, 실험군과 대조군의 동질성 검증은 t검정을 하였고 두 그룹의 집단의 차이 분석은 대응표본 t 검정(paired t-test)으로 분석하였다. 동질성 검사에 실험군과 대조군의 동질성을 확인 할 수 있었다. 전문심장소생술(ACLS) 수행기술 6가지에 대한 평가에서 시뮬레이션 교육을 받은 실험군이 교육을 받지않은 전통적 교육 방식의 대조군보다 모든 면에서 수행능력이 우수하였음을 증명하였다. 수행기술은 1. 심전도 2. 전문기기 3. 수액처치 4. 리더십과 팀워크 5. 의료지도 6. 이송중 평가 이상 6가지 이다. 일반적인 강의와 실습을 한 구급대원보다 시뮬레이션 교육을 받은 구급대원이 직무수행 능력이 향상된 것이 검증되었다 따라서 종합술기 과정에 있는 학생이나 임상에 종사하는 응급구조사에게 시뮬레이션 훈련과 교육이 확대 적용된다면 더 능숙하게 직무를 수행해 나갈 수 있을 것이며, 심정지 환자에게 제공되는 구급서비스가 향상될 것으로 기대한다.

Photodynamic Therapy에 의한 산화적 스트레스 조건에서 Helicobacter pylori의 Fur 단백질의 역할

박유나,김지훈,최성숙,Park, Yu-Na,Kim, Ji-Hoon,Choi, Sung-Sook 한국미생물학회 2011 미생물학회지 Vol.47 No.2

Helicobacter pylori균의 ferric uptake regulator (Fur) 단백질의 산화적 손상에 대한 역할을 연구하였다. H. pylori균의 fur 유전자를 제거한 돌연변이체를 만들고 wild type H. pylori균과 돌연변이체 균의 산화적 스트레스에 대한 반응을 비교하였다. 산화적 스트레스는 methylene blue와 660 nm 파장의 빛을 이용하는 광역학적 치료방법으로 유도하였다. 산화적 스트레스를 가한 실험조건에서 wt H. pylori와 돌연변이체의 생존력, DNA 손상의 정도를 비교 검토하였다. 그 결과 fur 유전자가 제거된 돌연변이체의 생균수가 wt에 비해 10,000배 가량 감소한 것을 알 수 있었으며 DNA의 산화적 손상의 marker인 8-hydroxy-2-deoxyguanosine (8-OHdG)의 양도 fur 유전자 제거된 돌연변이에서 wild type에 비해 3배 정도 더 생성됨을 확인하였다. 따라서 본 실험결과 H. pylori균의 fur 유전자가 PDT법으로 유도한 산화적 스트레스에 방어 기작을 하는 것으로 사료된다. The role of the ferric uptake regulator (Fur) of Helicobacter pylori in the oxidative stress was investigated in this study. A fur knockout mutant of H. pylori was constructed by replacing the fur gene with an aphA (kanamycin resistant marker) gene. Photodynamic therapy using methylene blue (MB) and 660 nm light was chosen to induce oxidative stress. The bactericidal effect of photodynamic therapy (PDT) was compared between wild type H. pylori and fur knockout mutant H. pylori. The degree of oxidative damage of DNA was confirmed using alkaline gel electrophoresis and an assay of 8-hydroxy-2-deoxyguanosine (8-OHdG). In control groups, the number of viable cells was maintained constantly during experiment. After PDT, the mutant H. pylori showed 10,000 times decreased viable cell number compared with wild type H. pylori. Depending on the exposure time of 660 nm light, the 3-fold increase in the concentration of 8-OHdG was observed in mutant H. pylori. The results of this study showed that H. pylori's Fur protein may play a role in oxidative stress induced by PDT.
