郭東日,洪聖均,李祥淵 최신의학사 1975 最新醫學 Vol.18 No.2

This study is intended to investigate the various factors of three hundred five adolescents of outpatients who visited the department of neuropsychiatry, Woo Sok Hospital, Korea University during the period from Jan. 1970 to Dec. 1972. The result were as follows: 1. As to age and sex distribution, the most frequent age group was 18 year old patients (18.0% of the study group). The male patient was highly distributed at the age of 18 and 20, and the female patient was highly distributed at the age of 16. 2. As to the diagnostic categories according to age groups, it was revealed that neuroses was the most common at the age of 12, 13, 16, 19 and 20, and schizophrenia was the most common at the age of 14. 15, 17 and 18. As a whole, male patient had a higher rate than female patient in schizophrenics and female patient had a higher rate than male patient in neurotics. And it was revealed that neuroses was the highest rate of 36. 1%, and schizophreia(35.7%), psychophysiologic disorders(12.5%), affective psychoses(9.8%) were the higher rate in this order(305 of the study group). 3. As to yearly diagnostic distribution, it was the author's impression that the psychiatric disorders of adolescence was on the increase in Seoul area. 4. As to the socio-economic status according to diagnostic categories, the middle upper classes tend to have relatively more affective psychoses or personality disorder and the middle lowers classes tend to have neuroses or schizophrenia. As a whole,' the most patients came from the middle lower classes families. 5. As to the number of previous psychiatric consultation, the cases of none-previous psychiatric consultation were 80.3%.

김승현,정인과,곽동일 大韓神經精神醫學會 1986 신경정신의학 Vol.25 No.4

In this study the authors observed changes in response to the dexamethasone suppression test (DST) in depressed patients receiving antidepressants. Among 20 subjects.15 were major depression and 5 were bipolar depression. The 8 of 20 subjects showed psychotic features, and 12 of them did not show any psychotic features at all. All subjects underwent weekly DSTs with simultaneous clinical ratings (Hamilton Rating Scale for Depression-HRSD), both at the day of admission and during treatment. Dexamethasone (Decadron. 1㎎)was administered orally at 11 PM on the day of admission and every Wednesday during subsequent weeks. The results of this study were as follows: 1) The 7 of 20 subjects (35%) were categorized as nonsuppressors and 13 (65%) were as suppressors. 2) There were no significant differences in age, sex, body weight, depressive subtype (unipolar vbipolar), length of admission, HRSD scores at admission and discharge, and clinical outcome between nonsuppressors and suppressors. 3) The results of DST were higher predictably among nonsuppressors than suppressors at the time of admission, but not significant difference at the time of discharge between these subgroups 4) The result of DST were higher among subjects with psychotic features at the time of admission. However, there were no significant differences in DST results at the time of discharge and frequency of nonsuppressive response for DST between these subgroups. 5) There was significant correlation statistically between weekly post-DST cortisol levels in plasma and simultaneous HRSD scores among nonsuppressors, but no significant correlation among suppressors.

憂鬱症에 關한 臨床的 硏究

郭東日 우석대학교 의과대학 1967 우석의대잡지 Vol.4 No.1

This paper is made of a study of 150 patients of depression treated in the Department of Neuropsychiatry, Soo Do Medical College Hospital during the period from April, 1962 through March, 1966. Cases covered in this paper of 56 males and 94 females. They were comprised from the following diagnostic categories; involutional depression, manic-depressive reaction, psychotic depression and neurotic depression. In order to distinguish neurotic depression from psychotic depression, the author applied a clinical scale of items to individual case to get either a bimodal distribution which would be taken as evidence for the two type concept, or a normal distribution which would be taken as evidence that two types do not exist. The results obtained were as follows: 1. In the pretesting study, the interrater relability on the 20 cases scored by two raters was 0.74 (Spearman β) which is significant at the 0.001 level confidence. 2. This study showed a positively skewed distribution but not a sharp division between two types in the distribution of category scale scores. 3. Eleven items out of 16 used in this study showed excellent and good predictors are course independent, though disorder, depressive mood, somatization, guilt, "quality" different, retardation, previous attack of mania and previous attack of depression, and the good predictors are precipitating factor and late insomnia. 4. The correlation between severity and category scale score is much significant (p<0.001). 5. The correlation between the category scale score and age is much significant (p<0.001), and the author found that clinically severe depression are common before the age of 40.

VIP患者

郭東日 大韓神經精神醫學會 1990 신경정신의학 Vol.29 No.3

In clinical practice, we encountered many difficult situations, especially we have strain of dealing with the entitled person. Current knowledges on the very important person(VIP) as psychiatric patient and VIP syndromee were briefly reviewed respect to the concept, the dynamic formulation(splitting and entitlemeent), the contributing factors(patient factors, therapist factors, treatment system factors and pathogenic social system factors) and the treatment strategies of the VIP synd-rome with discussion of clinical example. VIP syndrome result from dysfunctional intersection of personality and social system fac-tor in which a patient identified as VIP is able to convey and exaggerated sense of entitle-ment onto the social field in which the treatment occurs. For treating the VIP psychiatric patient, when attitudes of entitlemeent and reality-based importance do not interfere with the assumption by the VIP of the patient role, and when the psychiatrist and treatment team are in touch with potential difficulties that attend VIP treatment, then treatment has a good chance for success.

곽동일,정세운,김도형,황유상 한국항공우주학회 2014 한국항공우주학회 학술발표회 논문집 Vol.2014 No.11

헬리콥터 진동의 주요 가진원은 주로터이며 조종사와 승객들의 안락함을 위해 주로터에 의한 진동에 대응하는 것은 아주 중요한 문제이다. 대부분의 헬리콥터에는 수동형 또는 능동형 진동억제장치가 적용되어 있다. 국외선진업체들은 수동형 대비 적은 중량으로 고효율이면서 주기적 유지 보수가 불필요한 능동진동제어시스템으로 수동형 진동저감장치를 대체하는 추세에 있다. 또한 능동진동제어시스템은 모든 비행조건에서 만족할만한 성능을 발휘하기 때문에 만족도가 아주 높다. 수리온에서 이러한 성능이 발휘 되는지 확인하고자 능동진동제어시스템의 성능 시연 비행시험을 수행하였다. 본 논문에서는 수리온에 대한 능동진동제어시스템 성능 시연 시험의 수행과정, 수행기법 그리고 시험결과를 제시한다. The main source of vibration for the Helicopter is the main rotor and the main rotor-induced vibration is one of the main challenges for pilot and passenger comfortable in cockpit and cabin. Most helicopters have passive or active anti-vibration devices. There is a growing tendency for foreign advanced helicopter manufactures to replace passive with Active Vibration Control System(AVCS) which has the benefit of higher performance with lower weight and periodic maintenance unnecessary compared to passive. Also, AVCS is high satisfactory for its high performance overall maneuvers. Surion AVCS flight test campaign was performed in order to demonstrate a performance of AVCS for Surion. This paper shows procedure, technique and flight test results for AVCS performance demonstration flight testing.

AD는 노년기의 대표적인 퇴행성 중추신경계 질환으로서 다양한 인지기능 장애, 정신적 증상, 그리고 기능 장애를 초래하는 만성적 질병이다. 인지기능 장애로서는 기억 장애, 실어증, 실인증, 실행증, 시공간 구성 능력의 장애 등이 있다. 기분 장애, 망상, 환각, 수면 장애, 공격적 행동 등은 정신 증상에 속한다. 아직까지 원인적 치료는 불가능하므로 사망에 이르기까지 계속 진행한다. 임상증상이 발현한 이후의 평균 수명은 7-10년으로, 대부분은 폐렴으로 사망한다. AD is one of the most prevalent degenerative CNS diseases among the elderly. It is characterized by the insidious onset and relentless gradual progression of symptoms and is manifested with a variety of impairments in neurocognitive functions, mental symptoms and functions. There is no causative treatment for the condition. Average survival is estimated 7 to 10 years, ranging from 2 to 25 years, from the onset of clinical symptoms. Pneumonia is the most frequent cause of death in the late stage.

韓國人의 恐怖 對象

郭東日,李丙允 고려대학교 의과대학 1973 고려대 의대 잡지 Vol.10 No.1

It is attempted to clarify the fear objects of normal Korean people. One thousand and one hundred seventy one subjects out of about 3,500 subjects who satisfactorily answered the questionnaire of fear objects were selected in order to asses the fear objects. These subjects were assessed according to their levels of ages, sexes and residential (cultural and educational) backgrounds. In the questionnaire the subjects were requested that they describe 5 feared objects in the order of intensity of fearfulness. According to the intensity of fearfulness each levels of objects were given 5 points, 4 points, 3 points, 2 points and 1 point respectively. The results of this study were as follows: 1. The number of feared objects were most extensively expressed by the puberty and early adult groups except urban female puberty group. 2. As to the categories of the feared objects, the findings were as follows: 1) The feared objects of human category occupied more than 10% among all age groups, and there was no significant difference between each of the age groups. 2) The socio-economical fears were increased according to advancing age groups. 3) The feared objects of human relation were occurred about 20% from the beginning of puberty and early adulthood, then declined from adulthood. 4) The feared objects of nature and of circumstantial ones were highly expressed in childhood, then slowly declined with increasing age and these feared objects were occurred more in rural groups than urban groups. 5) The feared objects of atmosphere and of circumstantial ones were occurred less than 5% in all groups. 6) The fears of illness were occurred more than 10% in all groups except rural child group and most highly expressed by urban pre-puberty group. These fears steadily increased in mild degree with advancing ages. 7) The fears of accident were expressed more highly in the urban groups than the rural groups though it occupied below 7% in each urban groups except the urban adulthood group, in which it occupied 12.6%. 8) The fears of inanimate objects occurred less than 10% in all age groups. 9) The fears of unreal objects occurred more than 12.8% in all childhood, and then remarkably declined with increasing age but in rural male adult group it occupied 6.4% and in rural female adult group it occupied 16.9%. 10) The fears of animal objects occurred more than 13.0% in all childhood groups and then remarkably declined with increasing age but in rural adult group increased up to 16.9% and generally more highly expressed by rural groups than urban ones. 3. As to the common fear objects of each age group, the findings were as follows: 1) In the childhood, "demon", "snake" and "night" were dominantly expressed. 2) In the pre-puberty, "thief and burglar", "agent", "hoodlum", "teacher" and "corpse" were dominantly expressed. 3) In the puberty, "female", "examination", "changes of social situation", "social rejection" and "pollution" were dominantly expressed and differences of the feared objects between sexes began to manifest in this period. 4) In the early adulthood, "ambiguous future", "personal relation", "feeling of inferiority", "social corruption", "misunderstanding", "love" and "one's own self" were dominantly expressed and there was no significant difference between urban and rural as well as among the other age groups. 5) In the adulthood, "money", "poverty", "financial panic", "crime", "unexpected accident", "betrayal" and "education of children" were dominantly expressed, and the rural groups dominantly expressed "demon", "bugbear", "snake" and "tiger" which were also dominant in rural childhood. As a summary of this study it is suggested that the fear objects of normal Korean people varies according to their ages, educational and cultural backgrounds. In addition it was revealed that the most commonly expressed fear objects of Korean were "war", "night", "darkness", "death", "illness" and "demon". From these common fear objects of Korean people it is supposed that more primitive modes of thinking still prevails especially among rural groups.

한국형 기동헬기(KUH)는 국내 최초로 개발된 헬기로서, 2010년 3월 초도 비행을 시작으로 2012년 6월 체계 개발을 성공적으로 종료하였다. 비행시험 단계에서 다양한 진동문제가 발생하였으며 이를 제어하기 위해 적절한 진동저감장치를 설계하고 적용하였다. 한국형 기동헬기의 주요 진동 성분인 4Ω 주파수 진동 저감을 위해 주로터 블레이드, 주기어박스 지지부, 조종실, 승객실 그리고 조종좌석에 진동저감장치를 적용하였다. 본 논문에서는 한국형 기동헬기에 적용된 진동저감장치들의 해석 및 설계 기법과 비행시험 결과를 제시한다. Korean Utility Helicopter(KUH) is the first korean-developed helicopter. Its first flight was performed in March 2010 and then its development was completed successfully by June 2012. During flight test phase, KUH faced various vibration problems and appropriate vibration-reduction devices were designed and applied to solve the problems. The vibration-reduction devices were applied to main rotor blades, main gear box(MGB) supporting structure, cockpit, cabin and pilot seats to reduce rotor-induced 4/rev vibration. This paper shows design technique and flight test results for vibration-reduction devices that have been incorporated into KUH.
