Through the 2014 Donbas conflict and the 2022 Ukraine-Russia war, we are experiencing that the command of the air is no longer only secured by the Air Force. Long-range surveillance reconnaissance and strikes carried out by the Air Force could be replaced by drones and missiles, and the enemy’s aerial attacks could be controlled by air defense systems such as Panchir and portable anti-aircraft missiles, allowing ground forces to carry out maneuvers freely. In other words, it is much more advantageous for the air force and the navy to take control of the air through long-distance operations, and the ground forces should support them. Therefore, this study aims to consider the cost-effectiveness aspect of the delivery command of the air; it provides implications for quickly responding to enemy air attacks by developing the air defense weapon system, drones, missiles, precision-guided munitions, etc rather than focusing on expensive fighter jets. 2014년 돈바스 분쟁과 2022년 우크라이나-러시아 전쟁 사례를 통해 제공권은 더 이상 공군에 의해서만 확보할 수 있는 것이 아님을 경험하고 있다. 기존의 공군이 수행하던 원거리 감시정찰과 타격은 드론과 미사일로 대체할 수 있으며 적의 공중공격은 판치르와 휴대형 대공미사일 같은 방공무기체계로 국지제공권을 장악하여 지상군의 자유로운 기동 작전을 수행할 수 있다. 즉, 지금처럼 공군과 해군이 원거리 작전을 통해 제공권을 장악하는 것이 훨씬 유리하며 지상군은 이들을 지원해주는 작전개념이 더욱 적절하다. 따라서 본 연구는 이러한 제공권 작전 수행체계에 대해 값비싼 전투기에 집중하기보다 비용 대 효과성 측면을 고려하여 방공무기체계, 드론, 미사일, 정밀유도 포탄 등을 병행 발전시켜 적의 공중공격에 신속히 역공할 수 있도록 제공권 작전 수행체계에 대한 시사점을 제공하는 것이다.

단일 고선량 방사선 조사 후 발생한 백서의 척수세포 자멸사에 대한 Nimodipine 의 효과

이창인,정용구,김한겸,김철용,조태형 대한신경외과학회 2003 Journal of Korean neurosurgical society Vol.34 No.5

Objective:Radiation injury includes radiation necrosis and apoptosis. Though some of its mechanism in brain are reported, those in spinal cord are not determined yet. The purpose of this study is to see whether nimodipine, one of calcium channel blockers, is effective for the prevention of high dose irradiation-induced apoptosis in the rat spinal cord. Methods : Forty eight Sprague-Dawley rats were divided into four experimental groups, such as non-treated group(control group) after 5Gy and 10Gy irradiation(n=24), and nimodipine-treated group after 5Gy and 10Gy irradiation(n=24). Each group was divided by irradiation doses. After the drug was administered, the spinal cord was exposed to 5Gy and 10Gy dose of gamma rays using Ir-192. All spinal cord underwent histological examination at 4 hours, 8 hours, 12 hours after irradiation to evaluate the number of apoptotic cells. Apoptotic cells were detected by TUNEL assay, and determined by direct visual counting at×200, magnification Results : In nimodipine-treated group, apoptotic cell counts were reduced significantly, compared to that of control group after irradiation(p<0.05). Conclusion : These results suggest that nimodipine treatment may have effects on the prevention of radiationinduced apoptosis. If it could be established that calcium channel blockers inhibit radiation injury, they might be useful in radiation therapy. Key words:Radiation;Apoptosis;Nimodipine;Spinal cord;Rat.

Inferencing Strategy for Vocabulary Learning and Listening Comprehension

이창인 대한언어학회 2008 언어학 Vol.16 No.4

The Linguistic Association of Korea Journal, 16(4), 25-42. This research attempts to investigate the effect of teaching inferencing strategy in listening comprehension. The participants in the audio class studied "News & Media" class with MP3 voice files only, and the participants in the video class, on the other hand, were given the MP3 voice files and the video files related to the content of the selected news items. With these participants, two research questions were set up:1) Is teaching inferencing strategy effective in a fifteen week period? and 2) Is there any difference in learning inferencing strategy between higher-proficiency learners and lower-proficiency learners? Regarding the first question, two kinds of measurement were given: a vocabulary test and a listening comprehension test. Generally speaking, the video class who had multimedia visual information performed better than the audio class in both tests, which implies that the better performance of the participants in the video class was due to the inferencing strategy. Regarding the second question, the finding that more proficient learners performed better than less proficient learners empirically supports the assumption that in the high cognitive load condition, which exist in treatments with visual information in this study, low-verbal ability learners did not have sufficient cognitive resources available to process the aural and visual information while high-verbal ability learners had sufficient resources. This finding positively affirms Mayer's generative theory of multimedia instruction and cognitive load theory.

국방비전 2050 구현을 위한 군(軍) 인사법 개정방향 연구

이창인,박상혁 국제문화기술진흥원 2023 The Journal of the Convergence on Culture Technolo Vol.9 No.1

From a phenomenological perspective on military human resources to carry out the government's "Defense Vision 2050" project, this study presents the direction of revision of the military pension along with the age and continuous retirement age system under Article 8 of the Military Personnel Act and the promotion criteria under Article 33 of the Enforcement Decree of the Military Act. The Military Personnel Act and the Enforcement Decree of the Military Personnel Act, which was created 60 years ago, are contrary to the equity of the current situation in 2022, and the conflicts continue to be drawn in terms of internal and external aspects of military human resources carrying out the "Defense Vision 2050" project, which is the keynote of the government's policy. In addition, this is linked to the national financial burden of military pension finances. Therefore, this study began with the need to revise the Military Personnel Act so that excellent human resources can continue to be introduced into a military system and perform stable duties through retirement age guarantee systems rather than class retirement. 본 연구는 정부정책 기조인 ‘국방비전 2050’ 프로젝트를 수행할 군(軍) 인적자원에 대한 현상학 적인 관점에서 군(軍) 인사법 8조의 연령 및 근속 정년제도와 군인사법 시행령 33조의 진급 기준과 더불어 군인연금에 대한 개정 방향을 제시하는 연구이다. 즉, 지난 60년 전 만들어진 ‘군인사법’과 ‘군인사법’ 시행령은 2022년 현재 상황에서 본 제도는 시대적 환경에 따른 형평성에 어긋나며 특히, 정부정책 기조인 ‘국방비전 2050’ 프로젝트를 수행하는 군(軍) 인적자원들에 대한 내재적·외재적 측면에서 지속적으로 모순점이 도출되는 현상이기 때문이며 이는 군인연금 재정에 따른 국가재정 부담까지 연계되고 있다. 따라서 본 연구는 군(軍) 조직에 우수한 인재가 지속적으로 유입되고 더 나아가 우수한 인적자원들이 군(軍) 조직에서 계급정년이 아닌 정년보장 제도를 통해 국가 최후 보루인 군(軍) 조직에서 안정적인 임무를 수행할 수 있도록 군(軍) 인사법을 개정해야 하는 필요성에 출발한 연구이다.

Purpose: To determine the prevalence of severe distress and its correlates among Cheju medical college students. Methods: Data were gathered in December 2005, and all medical college students were included. Of a total of 170 medical college students, 52(30.6%), 41(24.1%), 37(21.8%), and 40(23.5%) were 1st, 2nd, 3rd, and 4th year students, respectively. The questionnaire for sociodemographic information included age, sex, year, hometown, accommodation, education level of parents, socioeconomic status of parents, GPA(grade point average), and standing. Subjective sense of health status, level of health concern, smoking habit, drinking habit(CAGE), sleep pattern, degree of obesity, and body image satisfaction were included to reveal health habits and health behaviors of the subjects. CES-D for depression, Psychosocial Well-being Index(PWI) for stress level, State-Trait Anxiety Inventory(STAI) for level of anxiety, and SCL-90-R(Symptom Checklist 90 revised) for level of general psychopathology were used Results: 1st year students were 4.338 times(95% CI; 1.412-13.324) more likely than other years to experience severe distress. Students who felt that they had insufficient time for relaxation showed 5.027 times(95% CI; 1.489-16.969) higher prevalence of severe distress than those who felt they had sufficient time for relaxation. Those with poor self-esteem were 18.347 times(95% CI; 5.484-61.382) more likely to experience severe distress than those with ‘good’ self-esteem. Conclusion: Offering various programs for improving coping skills, advanced counseling program, or tutoring system and providing sufficient relaxation timeby various methods, such as modifying curriculum, are needed to ameliorate severe distress.
