  • Background: A physically active lifestyle and regular exercise training incurs many health benefits. One recently recognized benefit of regular moderate exercise is stress reduction and immune enhancement. Thus, a physical stress such as exercise may act at any number of points in the complex sequence of events collectively termed the immune response. Although exercise causes many propound changes in parameters of immune function, the nature and magnitude of such changes rely on several factors including the immune parameters of interest; type, intensity, and duration of exercise; fitness level or exercise history of the subject; environmental factors such as ambient temperature and humidity. Methods: This study was undertaken to investigate the effect of different type of exercise on superoxide dismutase (SOD), neutrophils, and T lymphocytes of Sprague-Dawley rats. Sprague-Dawley rats were randomly divided into three groups; a non-Trained group (NTG, n=6), a swim-Trained group (STG), and a treadmill-Trained group (TTG). The exercise regimen was designed in a treadmill (5 times/5 days/week) during 8-weeks for TTG, and swim training (5 times/5 days/week) during 8-weeks for STG, and the volume of exercise training was the same in both groups. Results: 8 weeks of regular swim and treadmill training significantly increased liver SOD concentration however, muscle SOD concentration was not statistically significant. In the level of neutrophils, TTG and STG showed significant difference, compared to NTG. TTG was the highest level of neutrophils. In the level of immune cell counts, there was significant difference among TTG, STG, and NTG both in the spleen and thymus. Conculsion: In conclusion, it can be stated that eight weeks swim and treadmill exercise training has beneficial effect in improving immune response and antioxidant defence capacity by augmenting immune cells and SOD activities of SD rats.

  • 최근 1600년 경 예수회 아리스토텔레스주의자들 사이에서 벌어졌던 수학의 과학으로서의 지위에 관한 논쟁에 대한 관심이 급증하고 있다. 필자는 월러스, 디어, 그리고 만코수를 좇아 이 논쟁을 조금 더 자세히 살펴보고자 한다. 이를 위해 필자는 비앙카니가 수학의 본성에 관한 논고에서 중간과학을 논의한 바에 초점을 맞출 것이다. 디어와 월러스의 논의로부터 우리는 수학의 과학적 지위를 옹호한 이들과 부인한 이들 사이의 논쟁에 관한 비교적 훌륭한 조감도를 얻을 수 있다. 그러나 그 논쟁의 일반적 동기를 이해하는 일과 그 안에 내포된 변증적 전략과 전술의 정교함을 감식하는 일은 전혀 별개의 문제이다. 바로 이 단계에서 우리는 중간과학에 관한 비앙카니의 견해의 요점을 이해하는 데에서 어려움에 봉착한다. 비록 중간과학의 문제에 관해서는 침묵을 지켰지만, 만코수가 완벽한 증명, 수학적 설명, 그리고 원인의 문제에 관한 예수회 아리스토텔레스주의자들의 입장을 논의한 바는 역사적으로나 철학적으로나 모두 최고의 중요성을 지닌다. 필자는 그 논쟁에서 진실로 무엇이 쟁점이었는지를 보다 심도 있게 이해하기 위하여 피콜로미니와 비앙카니의 견해에 대한 만코수의 해석을 주의 깊게 검토하고 비판할 것이다.

  • Background and Purpose: To analyze $^{18}F-THK5351$ positron emission tomography (PET) scans of patients with clinically diagnosed nonfluent/agrammatic variant primary progressive aphasia (navPPA). Methods: Thirty-one participants, including those with Alzheimer's disease (AD, n=13), navPPA (n=3), and those with normal control (NC, n=15) who completed 3 Tesla magnetic resonance imaging, $^{18}F-THK5351$ PET scans, and detailed neuropsychological tests, were included. Voxel-based and region of interest (ROI)-based analyses were performed to evaluate retention of $^{18}F-THK5351$ in navPPA patients. Results: In ROI-based analysis, patients with navPPA had higher levels of THK retention in the Broca's area, bilateral inferior frontal lobes, bilateral precentral gyri, and bilateral basal ganglia. Patients with navPPA showed higher levels of THK retention in bilateral frontal lobes (mainly left side) compared than NC in voxel-wise analysis. Conclusions: In our study, THK retention in navPPA patients was mainly distributed at the frontal region which was well correlated with functional-radiological distribution of navPPA. Our results suggest that tau PET imaging could be a supportive tool for diagnosis of navPPA in combination with a clinical history.

  • 본고는 비디오아트의 초기 역사에서 비디오가 내재하고 있는 사회 변형적 가치를 문화적 실천으로 구체화하고 학제 융합적인 학습과 연구의 방법론을 제시함으로써, 사회의 관계적 회로의 심미화를 고안한 폴 라이언(1943-2013)의 예술 세계의 역사성과 미학적 함의를 검토한다. 이를 위하여 제2장에서는 1969년에 폴 라이언이 처음으로 참여했던 미술갤러리 전시 "창조적 미디어로서의 텔레비전"에 출품한 작품을 분석한다. 이 비디오설치 작품에서 라이언은 비디오를 하나의 커뮤니케이션 시스템으로서 제안하며 사이버네틱스의 '피드백' 개념을 실험한다. 이어서 제3장에서는 예술가 콜렉티브 '레인댄스 코퍼레이션'과 잡지 "래디컬 소프트웨어"에 참여한 라이언의 커뮤니케이션 테크놀로지에 대한 담론적 활동에 주목하였다. 이 시기 라이언은 비디오를 사이버네틱스의 확장을 위한 도구로 간주하였다. 마지막으로 제4장에서는 '환경적 현실에 대한 공유된 지각'에 기초한 생태적 접근법의 개발을 주로 다루었으며, 비디오 미디어가 사회의 변화와 커뮤니케이션을 위한 가장 효과적인 수단이 될 수 있다는 라이언의 인식을 확인하였다.

  • Objectives: Medical students represent a primary target for tobacco cessation training. This study assessed the prevalence of medical students' tobacco use, attitudes, clinical skills, and tobacco-related curricula in two countries, the US and Italy, with known baseline disparities in hopes of identifying potential corrective interventions. Methods: From September to December 2013, medical students enrolled at the University of Bologna and at Brown University were recruited via email to answer survey questions assessing the prevalence of medical students' tobacco use, attitudes and clinical skills related to patients' smoking, and elements of medical school curricula related to tobacco use. Results: Of the 449 medical students enrolled at Brown and the 1426 enrolled at Bologna, 174 Brown students (38.7%) and 527 Bologna students (36.9%) participated in this study. Italian students were more likely to smoke (29.5% vs. 6.1%; p<0.001) and less likely to receive smoking cessation training (9.4% vs. 80.3%; p<0.001) than their American counterparts, even though the majority of students in both countries desired smoking cessation training (98.6% at Brown, 85.4% at Bologna; p<0.001). Additionally, negative beliefs regarding tobacco usage, the absence of formal training in smoking cessation counseling, and a negative interest in receiving specific training on smoking cessation were associated with a higher risk of not investigating a patient's smoking status during a routine history and not offering tobacco cessation treatment to patients. Conclusions: Medical curricula on tobacco-related health hazards and on smoking cessation should be mandatory in order to reduce smoking among medical students, physicians, and patients, thereby improving tobacco-related global health.

  • In recent years, leisure time has received increasing attention in Korean society. Despite the growing interest, however, there are very few studies that explored shared leisure time, especially among married couples. In this light, the present study examined variations in shared leisure time by demographic characteristics and associations between shared leisure time and quality of marital relationship. We used the third wave of the national data KLoWF (Korean Longitudinal Survey of Women and Families, 9,997 19-64 years old women). The study sample included 5,965 married women with no prior history of divorce. Results showed that Korean wives reported very little shared leisure time with their husbands. Given that the mean of the shared leisure time reported by employed women was significantly lower than that of the un-employed, we speculated that the time constraint may be one of the major barriers to having leisure time with one's spouse among Korean married couples. Married women in their 30's had the most frequent couple leisure time. The younger wives in their 20s had more cultural leisure time with their husbands, but sharing outdoor leisure time was not related to their age. The higher level of education for women was associated with greater shared active leisure time. However, visiting a husband's family often took place regardless of the wives' education level. After controlling for age, years of education, job status and annual family income, shared active leisure time (i.e., cultural activity and exercise) was positively related to marital satisfaction. Visiting one's own family, however, was not considered a leisure activity for Korean wives. Rather, frequent family visits were related to lower marital satisfaction. Findings shed light on how leisure life of married women with spouses are intertwined with not only their socioeconomic status and but also marital relationship in culturally unique ways.

  • Why did Kim Jong Un turn his foreign policy upside down in a sudden? US naval blockade became one of candidates for the reason since it had been threatened by Trump administration for the first time in December 2017. Has the blockades worked well like that in the international politic history? This paper reveals the effectiveness of naval blockade on sanctioning in the peacetime. This research analyzes three hypothetical arguments about the naval blockade based on the result of empirical tests with TIES Dataset. First, sanctions by blockading are more effective in gaining political benefits than the other economic sanctions. It was ranked the 4th effective way of sanction out of 9. And 56.3% of pacific naval blockades without packaged economic sanctions were succeeded, whereas the possibility of success increase up to 61.2% when blockade has been imposed in accordance with the other type of economic sanctions. Second, blockades deter military collisions, even war. When it comes to military provocation issue, blockading sanctions gain political interest far more than the other type of economic sanctions. The possibility of the success reaches up to 74%. Also, there wasn't any historical cases of war incurred by blockading sanctions within 5 years after the blockade end. Third, policy makers just need 1.2 years on average to see the end of sanctions when they choose the naval blockade as the method of imposing sanction on the adversary. It is impressively short span of time in achieving political goal compared to the other types of sanctions which are need 9 years on average. North East Asia sea could be the next stage for a naval blockade sooner or later. Because China and Japan not only possess capabilities of blockade but also have will to impose blockades to the others if conditions are set. And even the North Korea with lots of submerging forces could be a blockading threat in the specific area. So, the Republic of Korea has to pay more attention and be prepared for naval blockading sanction.

  • 에듀테크에 대한 관심은 팬데믹 시기를 거치면서 급증하였다. 대면 교육이 불가한 상황에서 에듀테크는 교육현장을 중심으로 담론 확산의 장(場)이 되었고, 대중들의 주요 관심사가 되었다. 이에 본 연구는 전국 주요 일간지의 에듀테크 기사를 검토하여 주요 담론의 내용과 특징, 쟁점을 분석하고 이에 따른 교육현장의 과제를 밝혔다. 에듀테크 담론은 초기에는 교육적 도구로써의 유용성을 강조한 담론이 대부분이었으나, 팬데믹 시기를 거치면서 새로운 쟁점이 부각되었다. 테크놀로지의 활용을 넘어서, 학습자의 의지를 어떻게 유도하고 지속시킬 것인가가 쟁점이 되었고 과제가 되었다. 또한 공교육의 장으로써 학교현장의 기록과 평가에 대한 공정성의 확보, 이와 관련된 사람들의 개인 정보 보호의 문제 등도 민감한 쟁점이 되었다. 에듀테크의 적용 과정에서 특정 기술 기업과 관련된 특혜 논쟁 또한 쟁점이 되었다. 이것은 기술의 확산 과정에서 불가피한 것으로, 에듀테크 적용 과정에서 해결해야 할 또 다른 과제로 남았다.
