Purpose: This study was conducted to identify the quality of life (QOL) of adolescents who have inflammatory bowel disease. Methods: This was a descriptive comparative study, and participants were 58 adolescents with inflammatory bowel disease and 55 healthy adolescents. The Korean version of PedsQLTM 4.0 scale was used. Ten adolescents with inflammatory bowel disease were also interviewed. Data were analyzed with SPSS Win. Results: Average score on QOL for these adolescents was statistically lower (p<.001) than healthy adolescents, especially for physical and school functioning. QOL of the adolescents who had the disease for more than 4 years, and were taking 3 or more medications was lower QOL than other adolescents with this disease. In interviews, adolescents complained of physical malfunctioning. In emotional functioning, they worried about the reoccurrence of bloody diarrhea, and mood changes. As for social functioning, dietary restrictions, gastrointestinal symptoms, and poor peer relationships were primary concerns. Lastly, in school functioning, frequent absences and lower academic performance were problems. Conclusion: Considering these results, adolescents with inflammatory bowel disease felt anxious because of the uncertain origin of their disease and unpredictable course of the illness. Interventions should include diaries on food, along with education and counseling as nursing interventions.

Colon cancer is a leading cause of cancer-related deaths worldwide. Effects of walnut (Juglans regia L.) lipid extracts (WLEs) on the self-renewal capacity of cancer stem cells (CSCs) in colon cancer were investigated. The dominant component of WLEs was α-linoleic acid (64.6%), followed by α-linolenic acid (14.6%), and oleic acid (12.6%). A higher concentration of γ-tocopherol (37.1%) was also present than of α-tocopherol (0.6%). CD133+CD44+CSCs treated with WLEs showed inhibition of colony formation and sphere formation, indicating a decrease in the self-renewal capacity. Treatment with WLEs also resulted in down-regulation of protein levels, including Notch1, phospho-GSK3β (p- GSK3β), and β-catenin, which are associated with CSCs and the self-renewing capacity. WLEs rich in essential fatty acids and γ-tocopherol can exert therapeutic actions on colon cancer via targeting of CSCs.

With external air pollution forcing many people indoors, new methods of facilitating healthier indoor life are necessary. This study, therefore, investigates the effects of indoor oxygen concentration and respiration methods on biosignals and cognitive ability. The study included twenty healthy subjects who inhaled air through a mask from a gas delivery system. All subjects were asked to perform three types of breathing (nasal, oral, and oral breathing with high oxygenation) and respond to cognitive stimuli (rest close eye, rest open eye, 1-back and 2-back working memory tasks). The changes in cognitive load according to respiration were analyzed by measuring response time, accuracy, and biosignals to stimuli. The result showed that, in all three respirations, heart rate significantly increased with the increase in cognitive load. Also, in oral respiration, the airway respiration rate significantly increased according to the increase in cognitive load. The change appeared to compensate for insufficient oxygen supply in oral respiration during cognitive activity. Conversely, there was no significant change in airway respiration rate during oral respiration with a high concentration oxygen supply as in nasal respiration. This result suggests that a high concentration oxygen supply might play a role in compensating for insufficient oxygen concentration or inefficient oxygen inhalation, such as oral respiration. Based on the results of this study, a follow-up study is necessary to determine the impact of changes in the autonomic nervous system, such as stress and emotions, to find out more precise and comprehensive effects of oxygen concentration and breathing type. 대기오염 등의 영향으로 실내 활동 시간이 증가하는 상황에서 뇌기능과 신체활동 측면에서 보다 건강한 실내 생활 을 위한 다양한 방안에 대한 고려가 절실한 실정이다. 본 연구는 실내 산소의 농도와 호흡의 방법에 따라 인지능력과 생체신호에 어떤 영향을 미치는지에 대해 연구하여 보다 건강한 실내 일상생활을 제안하고자 한다. 건강한 성인 20 명을 대상으로 공기 전달 시스템을 통해 공급된 공기를 산소마스크를 통해 흡입하도록 하였다. 호흡 방법과 산소 농도에 따른 변화를 확인하기 위해 모든 피험자는 3가지 호흡(비강, 구강, 및 고농도 산소공급과 함께 구강 호흡)을 인지부하자극(눈 감은 휴식기, 눈 뜬 휴식기, 1-back 및 2-back 작업기억 과제) 별로 각각 수행하였다. 자극에 대한 반응시간, 정확도 및 생체신호를 측정하여 호흡에 따른 인지부하별 변화를 분석하였다. 그 결과, 3가지 호흡에서 모 두 인지부하의 증가에 따라 심박동수는 유의하게 증가하면서 인지부하와 높은 상관성이 있는 생체신호임을 확인하 였다. 또한 구강호흡에서는 분당 호흡 횟수가 인지부하증가에 따라 유의하게 증가하는 변화가 나타났으며, 인지활동 시 구강호흡에서 부족한 산소공급을 보완하기 위한 생체신호의 변화를 확인하게 되었다. 반면 고농도 산소공급과 함께 수행한 구강호흡에서는 비강호흡과 같이 분당 호흡 횟수의 유의한 변화는 없는 것으로 나타났다. 이는 고농도 산소공급이 구강호흡과 같이 비효율적인 산소 흡입이나 산소 농도가 부족한 환경에서 이를 보완해 주는 역할을 할 가능성이 있음을 시사한다. 본 연구 결과를 기반으로 후속 연구에서는 자율신경계 변화까지 분석하여 인지 뿐만 아 니라 심리에 미치는 영향까지 종합적으로 규명하고자 한다.

This study was aimed to determine influenza vaccination coverage in 2004 in Korean and investigate the factors associated with vaccination. Documentation of vaccination status and baseline data was conducted by a survey using questionnaire sheets. Baseline data and vaccination status were documented on 1465 people out of whom 60.1% received the influenza vaccine. Forth-seven percent of the responders were male; 4% were aged 1-12, 32% were aged 13-39, 32% were aged 40-64 and 32% were aged 65 or older. Twenty-three percent reported a chronic illness, increasing their risk for complications from influenza. Predictors of influenza vaccination were: older age (OR=11.7, 95% CI 5.1-26.8), the presence of chronic illness (OR=2.3, 95% CI 1.1-4.7), previous vaccination(OR=1.8, 95% CI 1.1-2.8), belief that influenza vaccine is effective in preventing influenza (OR=2.5, 95% CI 1.1-5.7) and education level (OR=1.7, 95% CI 1.0-2.7). Immunization rates were much higher in those who will take immunization again (OR=10.4 95% CI 5.5-19.6). Factors affecting the decision on immunization were self-determination (43.6%), public relations (24.1%), recommendation from family members or friends (22.4%) and consulting with health professionals (5.8%). The main reason not to take influenza vaccine was the thought that they are healthy (50.1%). Overall, influenza vaccine coverage was high in those aged 65 or older. Immunization against influenza was influenced more by existing medical problem and belief about th vaccine's effectiveness, rather than sex or residence.

This survey was carried out to investigate kinds and origins of flower languages of common flowering plants and standardize them. A flowering plant has about 5 kinds of flower languages. Differnt literatures have different flower languages for the same flowering plant. So differnt flower languages need to have standard flower languages. Flower languages originate from shape(8.0%) > color(7.5%) > characteristics(4.4%) > mythology and legend(4.9%) > scientific name(2.3%) > flowering time(1.8%) > perfume(0.9%) > and others(1.7%). The origin of 68.5% of flower languages was found to be obscure.

Changing Frames: China’s Media Strategy for Environmental Protests

정주연,Ming Zeng 경남대학교 극동문제연구소 2022 ASIAN PERSPECTIVE Vol.46 No.3

In the People’s Republic of China (PRC), the Chinese Communist Party (CCP) has remained stable despite frequent popular protests. Focusing on environmental protests, we attempt to explain how the CCP has utilized domestic news media to deal with protests and ensure regime stability. We chose five major protests against Para-Xylene (PX) and analyzed all of the People’s Daily Online (PDO) articles thereon since 2007. From the Hu Jintao to Xi Jinping governments, PDO’s collective portrayal of the anti-PX protests has dramatically changed from a symbol of democratic progress to an impediment to national industrialization and social stability. The systematically orchestrated media framing demonstrates that, instead of indiscriminately suppressing information on protests, the party has deliberately chosen when and what to permit and what images to project onto the protests. This article provides new insights into the CCP’s media strategy for popular protest and sheds light on how China’s authoritarian regime has maintained political legitimacy and social stability despite a considerable level of public discontent and deepening political oppression.

Still a Valid Unit of Analysis?: Globalization and the State in Comparative Political Analysis

정주연 고려대학교 일민국제관계연구원 2012 국제관계연구 Vol.17 No.1

Globalization poses potential challenges to comparative political analysis based on the state as the primary unit of analysis. When the diffusion of universal political and economic institutions, ideas, and norms across borders occurs the basis for comparison might be lost because the units being compared are not separate instances of the phenomenon we wish to study. Nor is it reasonable to make the conventional assumption that a country’s political institutions and policy outputs result primarily from the interplay of forces within that country. Under the pressures of neoliberal marketization, the state's policymaking autonomy and command over its territory is asserted to be considerably undermined as well. This paper analyzes the methodological and empirical challenges that globalization has posed on the state as a unit of analysis, and argues that the "challenges" are neither new nor fatal. The challenges have enabled the state to reinforce its capacity and brought the comparative scholarly interest back to the state.

‘어쩐지’의 의미 고찰

정주연 민족어문학회 2023 어문논집 Vol.- No.97

‘어쩐지’는 텍스트의 다양한 맥락에서 쓰인다. 문장을 수식하는 문장 부사의 용법 이외에도 문장과 문장 사이에서 관계 의미를 나타내는 문장 접속 기능을 하기도 한다. 문장과 문장의 접속에서 문장의 의미 층위를 구분하여 적용하면 ‘어쩐지’는 화자가 믿거나 판단한 명제와 그에 대한 근거를 연결시키는 기능을 하는 것으로 설명할 수 있다. 이는 Maat & Degand에서 제시한 인식 층위 인과 관계의 두 유형과도 일치하는 것이다. ‘어쩐지’의 양태 의미는 ‘의외성’, ‘기대논리’ 등으로 다루어졌다. 이러한 의미들은 ‘어쩐지’ 구문에서 화자에게 새로운 정보가 두 사태 간의 인과적 관계라는 점, 그 관계가 실재 세계의 관계가 아닌 화자의 인식적 관계라는 점에서 접속 의미와 관련하여 해석할 수 있을 것이다.
