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.

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.

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.

Most theories of war have paid too much attention to preventive attack cases between major powers, but paid too little attention to ones between major and minor powers and ones between minor powers.Taking this problem into account, the purpose of this paper is to offer a better theory, a complementary theory, than other theories of war, such as power transition theory and the existing version of offense-defense theory, in order to explain not only the probabilities of victory and deterrence related to preventive attack cases between great powers and minor powers but ones between minor powers. This paper argues that offense-defense theory of military strategy and technology is a better theory to explain effectively than the probabilities of victory and deterrence by preventive attack. In particular, this revised version of offense-defense theory suggested in this paper provides military strategy as another important factor because understanding offensive and defensive action and probabilities of victory and deterrence between opponents is not possible by looking only at offensive or defensive military technology, that is, the offensive or defensive character of particular weapons systems; it should be comprehensively analyzed by taking into account the combination of military strategy and military technology. As a new variable supplementing the existing version of offense-defense theory, military strategy is important especially in a weaker target state"s defense because an effective defensive strategy can offset the target state"s weaker defensive capability, which has inferior military technologies, compared to those of a stronger potential attacking state; it increases the probabilities of deterrence of preventive attack. On the other hand, an effective offensive strategy can increase a potential attacking state"s ability to successfully execute a preventive attack on a target state, even though it lacks advanced offensive military technologies; it increases the probabilities of preventive attack, including its possibilities of victory.

차량 ECU 소프트웨어 개발 표준인 AUTOSAR(AUTomotive Open System ARchitecture)는 MDSE(Model Driven Software Engineering)방법론을 따른다. AUTOSAR 는 MDSE 를 위해 VFB(Virtual Functional Bus)모델로 소프트웨어 구조를 표현하고, IB(Internal Behavior)모델로 행위를 표현한다. AUTOSAR 는 IB 모델과 ECU Configuration Definition 의 RE(Runnable Entity)-TASK Mapping 정보를 바탕으로 TASK 소스코드를 생성하는데, IB 모델의 한 RE 가 복수의 TASK 에 사용될 수 있어 RE 및 TASK 의 실행 흐름을 파악하는 것이 어렵다. 본 연구에서는 이러한 AUTOSAR RE 및 TASK 구조에서 기인한 모델 검증의 어려움을 해소하기 위해, AUTOSAR IB 모델과 ECU Configuration Definition 으로부터 프로그램 그래프를 작성하여 구체적인 TASK 와 RE 의 실행 흐름을 시뮬레이션 할 수 있는 시뮬레이터 매카니즘을 제안한다.

박준혁(Jun-Hyuk Park),김정범(Jung-Bum Kim),류설영(Seol-Young Ryu) 대한생물치료정신의학회 2006 생물치료정신의학 Vol.12 No.1

본 연구의 목적은 대학생들에서 인터넷 중독 발병과 연관이 있는 개인의 특성, 특히 기질성격(temperament and character)과 스트레스 반응에 대해 알아보고자 하였다. 연구대상은 부산 소재 남녀 대학생 212명이었고 한국판 인터넷 중독 척도(KIAS, 2001), 기질성격검사(TCI, 1994), 스트레스 반응척도(SRI, 2000)로 구성된 설문지를 사용하여 조사하였다. 인터넷 중독 여부 판단을 위해 인터넷 중독 척도의 평균 점수를 기준으로 25%ile이하의 점수를 얻은 집단을 대조군으로 하고, 75%ile 이상의 점수를 얻은 집단을 중독경향군으로 나누어, 인터넷 중독 여부에 따른 기질성격의 차이와 스트레스 반응양상에 대해 알아보았다. 기질성격검사 결과 기질차원에서는 인터넷 중독경향군과 대조군과의 유의한 차이는 없었으나, 성격차원의 하위요인에서는 인터넷 중독경향군이 대조군에 비해 자기지향성과 협조성이 유의하게 낮았으며 자기초월성은 유의하게 높았다. 스트레스 반응 검사 결과 인터넷 중독경향군이 대조군에 비해 스트레스 반응 전체 점수가 유의하게 높았고 하위요인으로는 우울과 좌절이 유의하게 높았다. 결론적으로 인터넷 중독은 기질 특성보다는 성격 특성과 더 관련이 있는 것으로 추정되며 치료적 측면에서도 성격 특성을 고려하여 이를 개선할 수 있는 정신 치료적 접근도 치료의 한 부분으로 필요할 것으로 예상된다. 또한 인터넷 중독은 스트레스 반응이 선행할 수 있으며 특히 우울과 좌절 반응양상이 선행될 가능성이 큰 것으로 추정된다. Object : The purpose of the study was to examine an individual characters related to internet addiction, in particular, temperament-character, and stress response in college students. Method : The subjects consisted of 212 college students in Pusan. To assess personality dimensions, stress response, and the degree of internet addiction, Temperament and Character Inventory(TCI), Korean Internet Addiction Scale(KIAS), Stress Response Inventory(SRI) was completed. Subjects were divided into two group depending on internet addiction ; subjects with less than 25%ile of internet scores in KIAS were grouping as 'control group' , and subjects with more than 75%ile of internet scores in KIAS were grouping as 'addiction tendency group'. Result : Current finding are as follows: 1) Among the score of TCI, two groups showed no significant difference on temperament dimension. However the score of self-directedness(SD) and cooperativeness(C) were significantly lower, the score of self-transcendence(ST) were higher in the addiction tendency group than in the control group on character dimension. 2) In the SRI, the score of total stress response were higher in the addiction tendency group than in the control group. Among the subfactor of SRI, depression score and frustration score were higher in the addiction tendency group than in the control group. Conclusion : These results suggest that internet addiction are related to character dimension that are affected by environment than the hereditary temperament dimension. Thus, the psychotherapeutic approach which could improve the character dimension would be considered in treatment of internet addiction. Also in stress response, especially depression and frustration are preceded internet addiction, there is a necessity for intervention.
