With the development of VR technology, the visual immersion of VR games has been greatly enhanced nowadays. There has been an issue that has been troubling players in previous VR games, which is motion sickness. Therefore, VR games have been limited in terms of game mechanics, game duration, and game scale, greatly reducing the immersive experience of visual immersion. However, <Half-Life: Alyx> is different from previous VR games in that players can actually perform spatial displacement in the game scene, rather than being fixed in one place for 360-degree observation and interaction. At the same time, compared to traditional games, VR games no longer need to rely on screens, and the complete visual immersion enhances the fun and playability of the game. This research focuses on the VR game <Half-Life: Alyx> to explore its immersive factors in terms of visual perception. Through in-depth analysis of elements such as color, texture mapping, lighting, etc. in VR games, it was found that the game creates a strong sense of visual immersion in these aspects. Through analysis, it is helpful to gain a deeper understanding of the factors that contribute to visual immersion in VR games, which has certain reference value for game developers and related professionals.

The study aimed to perform the qualitative analysis of food and nutrition informations offered in TV program by monitoring newscastings, health-related programs giving food and nutrition information, dramas for family, education programs for children, and information programs for elderly in major TV broadcasting station(KBS, MBC, SBS, EBS). In this study, statistical analysis were done for numbers of information items related to health or food and nutrition informations. Duration of program the main, subject, sources, evaluation criteria of the contents. Results of qualitative monitoring for TV program are as follows. For health-related informations major propotions of subjects for the newscastings were about diseases. Those for health information programs were about foods. Those for children-education programs were about groceries. Those for seniors’ information programs were about eating habits. The analysis of food and nutrition information sources for most of programs were interviews with specialist and normal person, and on-the-spot-investingations. For food and nutrition informations those were evaluated as inappropriate, the propotion of news was increased to 72.2% in 2003 from 49.3% in 2002. For health information programs, it was increased to 67.7% in 2003 from 54.0% in 2002. But, in drama the propotion of inappropriate scenes were decreased to 16.2% in 2003 from 63.2% in 2002. In children-education programs, it was 40.0%. In seniors’ information programs, it was 17.9% in 2002. The propotion of cases that the quantity of foods is inappropriate in the food scene of serial drama, decreased to 15.8% in 2003 from 28.6% in 2002. The rate of drinking scenes increased to 11.5% from 10.7%. The rate of smoking scenes decreased to 0.2% from 1.6% due to the broadcasting self-regulation of smoking scenes in dramas. In the newscatings and information programs, reasons of being evaluated as inappropriate was that they didn’t have any practical suggestions and proper intakes. There were also insufficient explanation for technical terminology, different comparison standard of nutritive value, and exaggeration for physiological effect of food. The drama contained a lot of unnecessary scenes of alcohol drinking, coffee drinking, midnight meal, and had more quantity of foods than the quantity needed for persons to the scene. As the result of this study, the rate of food and nutrition information were high, but the rate of information which was evaluate as appropriate was not sufficient. There are need to improve contents of information and to moniter the contents for consumer.

Purpose: This study aims to assess the influencing factors on the level of satisfaction with clinical training and to provide basic data for more efficient clinical training. Method: The study was conducted on 402 paramedic students who have experienced clinical training from September 6 until October 12 in 2011. The questionnaires consisted of 40 questions. We used SPSS 18.0 frequency analysis, technical statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression analysis. Result: 1. The level of satisfaction with clinical training showed significant difference between the frequency (F=8.837, p=.000) and clinical training managers (F=5.418, p=.001). 2. The level of satisfaction with clinical training showed the strongest positive correlation with the satisfaction of clinical training hospitals (r=.694, p=.000). 3. Multiple regression analysis revealed the most powerful predictor for satisfaction with clinical training was the satisfaction level of clinical training hospitals(48.2%) and the frequency of clinical training experiences(.8%), the preparation before the clinical training(5.4%), the total duration of clinical training(.7%), and the satisfaction of emergency department education(1.0%). These five variables accounted for 56.1% of the satisfaction of clinical training among paramedic students. Conclusion: As student's satisfaction of the clinical training increases, the quality of paramedics is expected to improve in the future. As a result, the future paramedics can be nurtured to be highly skilled in on-the-scene emergency situations after graduation.

Purpose: We aimed to improve the survival rates of out-of-hospital cardiac arrest patients. Methods: We analyzed data regarding cardiopulmonary resuscitation (CPR) outcomes and clinical characteristics of out-of-hospital cardiac arrest patients. The data included prehospital emergency medical service reports of 207 patients, 135 patients of Heart Saver, who survived over 72 hours after return of spontaneous circulation (ROSC) in Gyeonggi-do from January, 2012 to December, 2013. Data were analyzed using SPSS 18.0 descriptive statistics. Results: Among patients who achieved ROSC, 87.6% were men and 73.6% were aged 41-70 years; 86.7% were cases of witnessed cardiac arrest, and cardiopulmonary resuscitation was performed by bystanders in 65.9% of cases. The initial electrocardiogram showed ventricular fibrillation or pulseless ventricular tachycardia in 96.3% of patients. The call time was 1.0 minutes, arrival time was 6.3 minutes, time spent at the scene was 8.0 minutes, hospital arrival time was 10.0 minutes, and total CPR duration was 9.6 minutes. The certificate of them was paramedics in 89.6%. Conclusion: To improve the survival rates of out-of-hospital cardiac arrest patients, standard prehospital care for these patients and educational programs regarding CPR for lay rescues should be developed.

Purpose: The Armed Forces Trauma Center of Korea was established in April 2022. This study was conducted to report our 1-year experience of treating soldiers with open fractures of the lower extremity. Methods: In this case series, we reviewed the medical records of 51 Korean soldiers with open fractures of the lower extremity between April 2022 and March 2023 at a trauma center. We analyzed patients with Gustilo-Anderson type II and III fractures and reported the duration of transportation, injury mechanisms, injured sites, and associated injuries. We also presented laboratory findings, surgery types, intensive care unit stays, hospital stays, rehabilitation results, and reasons for psychiatric consultation. Additionally, we described patients' mode of transport. Results: This study enrolled nine male patients who were between 21 and 26 years old. Six patients had type II and three had type III fractures. Transport from the accident scene to the emergency room ranged from 75 to 455 minutes, and from the emergency room to the operating room ranged from 35 to 200 minutes. Injury mechanisms included gunshot wounds, landmine explosions, grenade explosions, and entrapment by ship mooring ropes. One case had serious associated injuries (inhalation burn, open facial bone fractures, and hemopneumothorax). No cases with serious blood loss or coagulopathies were found, but most cases had a significant elevation of creatinine kinase. Two patients underwent vascular reconstruction, whereas four patients received flap surgery. After rehabilitation, six patients could walk, one patient could move their joints actively, and two patients performed active assistive movement. Eight patients were referred to the psychiatry department due to suicidal attempts and posttraumatic stress disorder. Conclusions: This study provides insights into how to improve treatment for patients with military trauma, as well as medical services such as the transport system, by revising treatment protocols and systematizing treatment.

영화학자 뱅상 아미엘은 자신의 저서 <몽타주의 미학>을 통해 몽타주의 타입을 크게 세 가지로 나누어 소개한다. 서사 몽타주(Montage narratif)와 담론 몽타주(Montage discursif), 대응 몽타주(Montage decorrespondances)가 그 구분법으로, 이 세 가지의 부류는 거의 대부분의 영화들이 속하는 미학적 부류를 포괄하는 개념이 된다. 초기의 영화들은 편집의 본질적이고 기본적인 기능을 추구했는데, 이러한 성향은 시간이 흐를수록 연출자의 목표를 강화하기 위한 방향으로 수정되었다. 이처럼 서사를 결합시키는 '방법론'으로서가 아니라 '목적'을 지향하는 몽타주의 방식을 본고는 표현적 몽타주(Montage expressif)로 지칭하고, 이를 진정한 몽타주의 개념으로 받아들이며 논의를 시작한다. 몽타주 단계에서 표현적 몽타주 작업은 총 세 단계의 결정을 통해서 이뤄진다. 일차적으로 러시 필름 중 필요한 부분만을 선정하는 '선별'의 과정을 거친 후, 이 선택된 필름들을 일정한 순서대로 결합시키는 '결합'의 과정, 그리고 쇼트의 지속 시간을 고려해 장면연결을 결정하는 '연결'이 몽타주의 마지막 단계가 된다. 물론 예외는 있다. 고전적 서사의 픽션 영화가 클로즈업을 사용할 때, 혹은 모델이나 중성적 동물의 오브제를 사용할 때 영화는 관객의 감정을 끌어당기는 '담론 몽타주'나 '서사 몽타주'가 아닌, '대응 몽타주'의 경향을 유도하고, 이는 몽타주의 일반적 의미를 거스르는 측면에서 예외라 할 수 있다. 본 연구는 이처럼 클로즈업이나 대응몽타주가 사용하는 '콜라주'를 통한 연결, 혹은 '불확실한 연관성'을 지닌 작품의 몽타주 경향을 '현대영화의 파편화(fragmentation) 경향'이라 명명하며 이를 분석하려 한다. 현대영화에서 몽타주의 파편화는 영화의 연속적이고 구조적인 속성들을 깨트리고, 영화의 표면에 가시적으로 드러나는 서사(narration)의 구조를 혼동시킨다. 이처럼 클로즈업에서 시작된 몽타주의 파편화의 경향은 현대적 이미지의 확장성에 관한 해답을 줄 수 있으리라 본고는 바라보고 있다.

Objectives: This study was conducted to investigate the emotional characteristics of the patients within one year after stroke using the Core Seven Emotions Inventory-Short Form. Methods: It analyzed the medical records of 39 stroke patients who had visited W University hospital and completed the Core Seven-Emotions Inventory-Short Form (CSEI-S), the K-MBI, the PWI-SF, and the HADS. Patients data were analyzed by descriptive analysis, frequency analysis, the Mann-Whitney U test, and the nonparametric test of the CSEI according to the period of stroke onset in patients and Spearman's correlation analysis using the SPSS (Statistical Package for the Social Science, IBM, United States of America) Version 23.0. Results: First, in the case of depression, all subjects were in the danger group, although more than half of the joy, anger, thinking, sadness and fear were included in the normal group in the shortening of the key seven-point scale. Secondly, in measuring the social and psychological stress and hospital anxiety and depression, social and psychological stress were indicated to be a potential danger group, while anxiety and depression were shown to be a healthy group. Thirdly, the emotional characteristics were explored according to the sub-factor of the shortening of the key seven-figure emotional scale after being classified within two months, between two and six months and over six months depending on the duration of the outbreak. As a result, statistically significant, Joy was the highest score over six months and the lowest score between two and six months. On the other hand, the case of depression was depicted to be significantly lower at over six months, and was highest between two and six months. Finally, the correlations on each scale were statistically significant. Conclusions: This study provided that the CSEI-S can be used to simply to measure the emotions of patients according to the period of the onset of stroke in the clinical scene.
