Effects of High­Caffeine Energy Drink on Concentration, Anxiety, and Vital Signs in High School Female Students

정미현 인문사회 21 2023 인문사회 21 Vol.14 No.2

This study aimed to investigate the effects of high­caffeine energy drink consumption on concentration, anxiety, and vital signs among adolescents. A pretest­posttest design for a single group was employed, and a total of 30 high school female students were recruited. The Learning Immersion Scale for concentration and the Korean State­Trait Anxiety Inventory for anxiety were used. Vital signs, including blood pressure, pulse rate, respiration rate, and body temperature, were assessed. Descriptive statistics were conducted to describe pre­ and post­tests of concentration, anxiety, and vital signs. Paired t tests and Wilcoxon signed rank tests were used to compare differences in pre­ versus post­energy drink consumption for concentration, anxiety, and vital signs in the study. The results indicated that there were significant differences in state anxiety, pulse rate, and body temperature before and after consuming the energy drink. However, there were no significant differences observed in concentration, trait anxiety, systolic and diastolic blood pressure, and respiration rate. This study suggests that high­caffeine energy drinks can increase anxiety but do not have a significant effect on concentration. These findings emphasize the importance of further research to fully understand the potential risks and benefits of energy drinks.

아이리스 마리온 영의 정의론의관점에서 본 츠빙글리 연구

정미현 한국기독교사회윤리학회 2016 기독교사회윤리 Vol.34 No.-

본 논문의 목적은 여성정치 철학자 아이리스 마리온 영의 정의를 향한 책임적정치론의 관점에서 종교개혁자 훌드리히 츠빙글리의 윤리에 대하여 고찰하는 것이다. 이러한 연구의 한 접근 방법으로 시민 공동체의 정치적 책임의식과 공동체적 의식을 고양시키는 사회윤리적 관점에서 영과 훌드리히 츠빙글리와의 대화를시도해 보고자 하였다. 21세기에 미국에서 살았던 한 여성 정치철학자와 16세기에 스위스에서 살았던 한 남성 종교인과의 대화가 가능하다고 보는 이유는 다음과 같다. 이들에게서 첫째 정의를 향한 기본 의식이 강하게 자리매김 되었고, 둘째 정치적 책임과 공동체성이라는 기본적 화두를 접촉점으로 설정할 수 있기때문이다. 이러한 교집합의 가능성을 바탕으로 본 논문의 본론에서는 첫째 영과츠빙글리의 특성을 제시하는 억압과 정의에 대한 개념이해와 프레임을 제시하였다. 영은 억압과 지배의 다섯 가지 유형의 틀을 제시하고 그 안에서 정의론을펼치는데, 그녀는 분배 패러다임으로 설명될 수 없는 부정의를 포함하여 분배부정의 뿐 아니라, 다각적인 억압이 분배 문제를 넘어서 존재함에 주목하게 한다. 둘째 사회구조와 정의, 그리고 죄와 책임성의 문제를 츠빙글리 시대의 용병문제를 둘러싼 상황과 금식규정문제와 영의 논리 전개의 틀에서 교차적으로 살펴보았다. 그녀의 접근법은 지금까지의 남성 중심적 정의론이 제시한 분배 정의이론의편협성을 수정하고, 사회부정의와 억압의 복합적 현상을 젠더담론에서 보완하였으며 민주적 협치 체제를 강화하도록 촉구하는 의의를 가져왔다. 정의와 공공의책임성을 강화하고자 했던 츠빙글리의 사회윤리는 단순히 이론으로 그친 것이아니라, 종교개혁을 통하여 실제 스위스 사회의 변화를 가져오게 했었다는 점에서 영의 이론적 한계를 신학적으로 보완하고 또한 극복할 수 있는 단초를 제공한다고 보겠다. 본 논문은 영의 대안적 해법인 이상적 도시이론의 적용 한계성을츠빙글리가 짚어낸 당시 도시화의 한계와 지구화적으로 현재적으로 드러나는 도시화의 문제성을 중심으로 간략히 비판적으로 검토하며 마무리 되었으나, 향후이 부분에 대한 별도의 심도 깊은 연구주제로 발전될 수 있겠다. The aim of this article is to inquire into the ethical perception of Huldrych Zwingli utilizing the view point of Iris Marion Young regarding the political responsibility for Justice. In order to make a kind of dialogue between Iris M. Young and Huldrych Zwingli the author has focused on the social ethic for political responsibility and the goodness of community which have common grounds. The reason why this kind of comparison is possible between a Swiss reformer of the 16th century and a US American female scholar of the 21st century is that they share a common interest regarding the consciousness of justice and social political responsibility. This article is composed by two major parts: firstly, it introduces the perception of I. M. Young regarding five faces of oppression and H. Zwingli regarding oppression and justice. Young considers not only the injustice of distribution, but also the whole complexity of oppression and injustice. Secondly, it deals with issues of social structure, justice, sin and responsibility regarding mercenaries, the incident of breaking the fast by Zwingli and the frame of oppression of Young. Her approach corrects male dominant understanding of discourse about justice and includes the aspect of gender for examining injustice in society. This is her achievement of seeking social justice in a democratic government. The efforts of Zwingli who sought justice and public responsibility resulted not only in an idealistic theory, but also brought about the example of transformation for Swiss society through reformation. Thus it can offer useful clues for correcting and overcoming flaws in Young’s theory. Her option of and ideal City Life has certain limitations for application to reality. Even though the article concludes with a short critical comments including Zwingli’s point of view and the contemporary global problem of urbanization, it requires further research in order to provide an optional solution.

방사선 조사 망상골이 외방형 골형성에 미치는 영향

정미현,허익,권영혁,박준봉,정종혁,Chung, Mi-Hyun,Herr, Yeek,Kwon, Young-Hyuk,Park, Joon-Bong,Chung, Jong-Hyuk 대한치주과학회 2007 Journal of Periodontal & Implant Science Vol.37 No.4

The purpose of this study was to evaluate exophytically vertical bone formation in residual ridge of the beagle dog by the concept of guided bone regeneration with a titanium reinforced e-PTFE membrane combined with irradiated cancellous human bone. Twelve male beagle dogs(mean age 1.5 years and mean weight 12kg) were used for this study. The alveolar ridges after extraction of all mandibular premolars were surgically and horizontally removed. At 8 weeks after extractions, full-thickness flap was reflected and cortical bone was removed with round bur and copious irrigation. Rectangular parallelepiped(10mm in length, 5mm in width, and 4mm in height) bended with titanium-reinforced e-PTFE(TR e-PTFE) membrane was placed on the decorticated alveolar ridge, fixed with metal pins and covered with full-thickness flap and assigned as a control group. Test groups ere treated with TR e-PTFE membrane filled with irradiated cancellous human bone. Of twelve beagle dogs, four control dogs and four test dogs without membrane exposure to oral cavity were sacrificed at 8 and 16 weeks respectively. The surgical sites were dissected out, fixed in 4% buffered formaldehyde, dyed using a Villanueva staining technique, and processed for embedding in plastic resin. The cutting and grinding methods were routinely processed for histologic and histomophometric analyis of exophytic bone formation as well as statistical analysis. The results of this study were as follows: 1. Exophytic bone formation in the both of experimental groups was increased respectively after surgery from 23.40% at 8 weeks to 46.26% at 16 weeks in the control groups, from 40.23% at 8 weeks to 47.11% at 16 weeks in the test groups(p<0.05). 2. At 8 weeks after surgery, exophytic bone formation was made 40.23% in the test groups and 33.40% in the control groups. Exophytic bone formation was significantly made in the test group more than in the control group. At 16 weeks after surgery, exophytic bone formation was made 44.11% in the test groups and 46.26% in the control groups. Exophytic bone formation was made in the test groups more than in the control groups, but there was no statistically significant differences. 3. The membrane was fixed with metal pins to closely contact it to the bone surface. So, collapse and deviation of the membrane could be prevented and in growth of connective tissue also could be blocked from the periphery of the membrane. On the basis of these findings, wee suggest that intraoral experimental model for exophytic bone formation may be effective to evaluate the effect of bone graft material. And it indicates that combined use of membrane and ICB graft material is more effective than use of membrane only for exophytic bone formation.

Minocycline 국소 약물 방출 제제의 치주질환 치료 효과

정미현,권영혁,허익,이만섭,박준봉,Chung, Mi-Hyun,Kwon, Young-Hyuk,Herr, Yeek,Lee, Man-Sup,Park, Joon-Bong 대한치주과학회 1998 Journal of Periodontal & Implant Science Vol.28 No.1

The purpose of this study was to evaluate the clinical and microbiological outcomes following the use of 30% minocycline-loaded polycaprolacton film and 2% minocycline-loaded gel that was applied locally into pockets combined with scaling and root planing. 25 human subjects who were non-pregnant, non-lactating, aged 20-50 and diagnosed as moderate to advanced adult periodontitis were enrolled. Subjects were excluded if they had a history of severe acute or chronic systemic disease, if they required antibiotic prophylaxis for dental treatment for any reason, or if they reported a history suggestive of hypersensitivity reactions to minocycline or tetracycline. 4quadrants that had several teeth with a 5-8mm probing pocket depth and radiographic evidence of alveolar bone loss for each patient were selected and divided into test sites and control sites according to the split-mouth design. Scaling and root planing was done for each site at baseline(0week). Test sites received the minocycline gel and strip and control sites had saline irrigation. The patients received both treatments simyltaneously. Subgingival irrigation of sterile saline was applied to the control sites for approximately 30 seconds. Minocycline strip and gel was applied into the periodontal pocket at 1, 2, 3, 4 weeks each after scaling and root planing in the test sites. The clinical and microbiological measurements were made at baseline and at the follow-up visits 6, 10, 14, 20 weeks. The results of this study were as follows; 1. The sulcular bleeding index, probing pocket depth and Periocheck test was significantly reduced and the relative proportions of spirochetes and motile rods were significantly reduced and the proportion of cocci was correspondingly increased, in locally delivered minocycline strip group compared to saline irrigation group. 2. In locally delivered minocycline gel group, The effect was the same with minocycline strip group as compared with saline irrigation therapy. 3. There was no significant differences between minocycline strip group and minocycline gelgroup. In conclusion, minocycline HCl local drug delivery combined with scaling and root planing may provide added improvement of clinical and microbiological responses by inhibiting bacterial recolonization of treated sites. It is suggested that the local administration of minocycline-HCl in the periodontal pocket is effective when combined with subgingival mechanical debridement.

Revisiting the Issue of US Military Prostitution and Culture of Militarism in Post Korean War

정미현 한국민중신학회 2017 Madang: Journal of Contextual Theology Vol.- No.27

This article describes three subjects: first, exclusive culture relating to prostitution on US military camps, second, indigenization of militaristic culture and gender bias, third, overcoming hostility within Christianity. Due to a lack of awareness and information about mechanism of prostitution on US camps, it is important to draw the attention of the public to this subject. It shows how indigenization of militarism and gender bias in Korea increase hostility and exclusivism. The article stresses the necessity of pursuing a culture of life-centered hospitality within Christianity as well as in society. In order to break down barriers toward the other and to promote awareness of peace and reconciliation with each other and to increase hospitality and to decrease hostility, we need an alternative climate and to transform the culture of militarism. It warns against militarism driven by right wing nationalistic orientation and the capitalistic interest of a minority group. Performance of gender justice in an intersectional way is important to create a new perception of masculinity and femininity by militarism driven culture in Korea. It concludes with a look ahead to what the study of militaristic culture may still bring, and seeks a permanent peace treaty and reconciliation within the Korean peninsula.

Seeking the Lost Threefold Thoughts: Relationships with God, Earth and Human beings

정미현 한국민중신학회 2014 Madang: Journal of Contextual Theology Vol.0 No.22

This article is composed of three parts. The first part is an introduction ofKorean threefold thought. The second illustrates the marginalized Christiantradition which has some commonality with this threefold thought. Thethird and last part is an attempt to apply these lost traditions in order torestore the Korean sprit in this neo-liberalism affected era and to practice itin daily life. Korean culture is based on the threefold thought and principal regardingto God, Earth and Human. In this culture, myth and religious elements arewidely observed showing threefold thought’s motive and harmony. Thepurpose of this article is to explore these components in various areas. This basic overall traditional Korean principal has some commonalitywith marginalized Christian traditions. A combination of Korean thoughtand this Christian tradition could contribute to understanding the Christianspirit fully because it is a comprehensive approach to a threefoldrelationship with God, human beings and Nature. The last part of this essay demonstrates some examples from recentKorean history regarding environmental issues which are also connectedwith patriarchal masculinity in militarism, boundless greed in neoliberalismand mass spiritual destruction on behalf of material richness andexternal growth. This article ends with the suggestion of changing thedemilitarized zone to a dream making zone toward transforming oursociety.

SNS의 교육적 활용에 관한 국내 연구동향 분석

정미현,김재현 이러닝학회 2016 이러닝학회 학술발표대회논문집 Vol.7 No.1

본 연구는 SNS의 교육적 활용에 관련된 연구가 어떻게 전개되어 왔는지를 살펴보기 위해 진행되었다. 이를 위해 2011년부터 2015년까지 최근 5년 간 KCI에 등재된 총 43편의 논문을 대상으로 분석하였다. 그 결과 SNS의 종류 중 페이스북을 활용하고, 대학생을 대상으로 하는 관련변인연구가 가장 활발한 것으로 나타났다. 하지만 최근 SNS 사용자의 실제 이용량이 줄어들고 있는 추세와 같이 2014년을 기점으로 논문 수가 줄어들고 있어 향후 관련 연구 시 학습자의 SNS 이용 지속가능성에 대해 충분히 고려해야 함을 시사한다.
