Objectives Haenyeo are Korean professional women breath-hold divers in Jeju island. The aim of this study was to investigate the clinical characteristics of depressed Haenyeo group, compared to non-Haenyeo depressed group. Methods This study included 75 Haenyeo and 340 non-Haenyeo with depressive disorders recruited from the Dementia Early Detection Program in Jeju island. Structural diagnostic interviews were performed using the Korean version of Mini International Neuropsychiatric Interview. All patients completed the questionnaires, including the Subjective Memory Complaints Questionnaire (SMCQ), the Patient Health Questionnaire-15 (PHQ-15), and the Blessed dementia scale. Depression was evaluated by the Korean version of short form the Geriatric Depression Scale (K-SGDS) and cognition was assessed by the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) assessment packet. Results Although the mean scores of the K-SGDS were similar between Haenyeo and non-Haenyeo depressed groups, the Haenyeo group showed a higher mean score on the PSQ-15 (p < 0.001, ANCOVA adjusting for age, the K-SGDS and education). The Haenyeo group showed poorer performance on the Korean Version of Frontal Assessment Batter (p < 0.001), the Mini-Mental State Examination in the Korean version of the CERAD Assessment Packet (p < 0.018), the word fluency test (p < 0.001), and the word list memory test (p = 0.012) in ANCOVA adjusting for age and education. The mean SMCQ score was higher in the Haenyeo depressed group than in the non-Haenyeo depressed group. Conclusions The Haenyeo depressed group shows cognitive dysfunction, especially frontal lobe dysfunction, compared to the non-Haenyeo depressed group, indicating the Haenyeo depressed group may have more severe frontolimbic dysfunction due to chronic exposure to hypoxia. The Haenyeo depressed group suffers more somatic symptoms than the non-Haenyeo depressed group.

테러와의 전쟁에 관한 미국 내 신문의 이념적 편향 연구: 2006년 이스라엘-헤즈볼라 전쟁을 중심으로

박준혁 ( Jun Hyuk Park ) 국방대학교 안보문제연구소 2011 국방연구 Vol.54 No.1

본 논문의 연구목적은 미국이 직접적으로 개입되지 않은 테러와의 전쟁과 관련한 사례들 중 테러 및 이에 대한 피해 당사국의 대응에 대해 미국 내 주요 신문들이 어떠한 형태의 이념적 편향 틀을 가지고 보도하였는가를 분석하고자 한다. 가령, 테러단체를 비이성적, 비합리적 조직으로 묘사하면서 군사력을 사용해서라도 반드시 일망타 진해야 함을 시사하는 언론이 있을 수 있는가 하면, 테러리즘의 근본적인 발생원인과 테러와의 전쟁으로 인해 참상을 겪는 무고한 시민들에 초점을 맞춤으로써 이들 테러 단체에 대한 무력응징이 바람직하지 않음을 시사하는 언론이 있을 수도 있다. 본 논문은 2006년에 발생한 이스라엘과 헤즈볼라 간 전쟁을 테러와의 전쟁사례로 선정하였다. 연구대상 신문으로는 자유주의적 성향의 뉴욕타임즈와 워싱턴포스트, 보수주의적 성향의 워싱턴타임즈와 시카고트리뷴을 선정하여 이들 신문들이 이스라엘-헤즈볼라 전쟁을 어떠한 형태의 이념적 편향 틀을 가지고 보도하였는가를 비교분석하고자 한다. The research focus of this paper is to analyze what kinds of frames of ideological bias major American newspapers have, in order to report the response of a victim nation to terrorist actions against it, particularly in cases of the War on Terror that do not directly involve the United States. For example, there would be some press that suggests a terrorist organization should be destroyed by the use of military force depicting that it is unreasonable and irrational, while there would be other press that implies a military retaliation is not desirable by focusing on the causes of a terrorism and innocent people who have gone through the disastrous scenes triggered by the war on this terror. This paper selects the 2006 Israel-Hezbollah War as a research case of the War on Terror. Liberal-leaning newspapers such as the New York Times and the Washington Post and conservative-leaning newspapers like the Washington Times and the Chicago Tribune are chosen for this investigation. This paper compares and analyzes what kinds of frames of ideological bias these newspapers have in reporting the Israel-Hezbollah War.

사상자 회피 혹은 사상자 용인?: 이라크 전쟁에 대한 미국민 지지도 재평가

박준혁 ( Jun Hyuk Park ) 연세대학교 사회과학연구소 2011 社會科學論集 Vol.42 No.1

Scholars have long debated the validity of the casualty-aversion hypothesis suggested by Mueller (1973), meaning that military casualties in war increase, the public`s support for war decreases. Despite significant advancement in understanding the connection between public attitudes and war, numerous studies fail to recognize that terrorist incidents beyond the given war zone under investigation-defined as external incidents -can pose a new problem for the casualty-aversion hypothesis. However, Burk`s (1999) meaningful study shows that casualties suffered from terrorist attacks in Lebanon reinforce the public`s support for the War on Terror. Burk`s finding directly opposes the casualty-aversion hypothesis, which can newly be defined as casualty-acceptance hypothesis. Based on Burk`s finding, the central question in this study is as follows: Do external incidents such as Al-Qaeda`s terrorist attacks in Madrid and London reinforce the U.S. public`s will and therefore, they reduce public disapproval for the Iraq War, aligned with the casualty-acceptance hypothesis? The War in Afghanistan can also be associated with the Iraq War. Therefore, this paper attempts to investigate the impacts of these three external incidents on U.S. public support for the Iraq War in relation to the casualty-aversion and casualty-acceptance hypotheses.

스러스트 래버린스 실을 배면에 갖는 원심형 임펠러의 축력 해석

박준혁(Jun Hyuk Park),김태호(Tae Ho Kim) 한국트라이볼로지학회 2021 한국트라이볼로지학회지 (Tribol. Lubr.) Vol.37 No.1

This study describes the effects of a thrust labyrinth seal applied to the backside of a centrifugal impeller on the axial thrust force for high speed turbomachinery. The bulk flow model using Neumann’s equation calculates the seal cavity pressures and leakage flow rate of the thrust labyrinth seal based on three configurations: teeth-on-rotor (TOR), teeth-on-stator (TOS), and interlocking labyrinth seal (ILS). Prediction results show that the ILS is superior to the TOR and TOS in terms of leakage flow rate. A mathematical model of a centrifugal impeller with a thrust labyrinth seal on its backside calculates the force components corresponding to the impeller inlet, shroud, impeller backside outer, backside seal, and backside inner pressures. A summation of the force components renders the total axial thrust force acting on the centrifugal impeller. The Newton-Raphson numerical scheme iteratively calculates the pressures and leakage flow rate through the impeller wall gap. The prediction results reveal that the leakage flow rate and total axial thrust force increase with rotor speed, and the ILS significantly decreases the leakage flow rate, whereas it slightly increases the axial thrust force when compared to TOR and TOS. Increasing the seal clearance causes an increase in the leakage flow rate and a slight decrease in the axial thrust force with the ILS.
