항공기의 플러터 및 진통소음 특성은 장기간에 걸친 다양한 비행시험을 통해서만 획득 가능하며, 생성된 방대한 양의 데이터를 효율적으로 축적하기 위해서는 특별히 설계된 데이터베이스 시스템이 필요하다. 이에 따라 MS-Access를 기반으로 하여 T-50 고등훈련기 비행시험 시 측정된 플러터/진동소음 환경 데이터를 처리하는 데이터베이스 시스템을 개발하였다. 개발된 시스템은 항공기 비행시험과 관련된 자료 항목, 관련 항목으로 구성된 테이블, 그리고 작성된 테이블들을 논리적으로 연결한 관계형 데이터베이스로 구성되며, 비쥬얼 베이직과 구조적 질의어를 이용한 데이터 검색 GUI(Graphic User Interface)를 구현하여 직관적인 검색이 가능하도록 되어 있다. 개발된 시스템을 이용하여 플러터/진동소음 데이터의 축적 및 요구도 검중에 효과적으로 활용하였다. The flutter/vibroacoustic characteristics can be acquired by conducting flight tests with various conditions for a long period of test. Accordingly it is indispensable to build a specially designed database system to efficiently accumulate the enormous data obtained from flight tests. Hence, T-50 Flight Test Database System(FTDS) based on MS-Access is developed to handle the flutter/vibroacoustic environment data obtained from flight tests. The developed system is structured with the items related to aircraft flight test, the tables composed of the relevant items and a relational database logically connecting the tables. The T-50 FTDS is implemented with data searching GUI(Graphic User Interface) programed with Visual Basic and Structured Query Language to make intuitive searches over the stored data. The developed system has been used for accumulating the flutter /vibroacoustic data and verifying vibroacoustic Specifications.

In this review article, the author tried to discuss how to become old in way of being respectable and dignified aged man in 'Neo-Elderly Model' in 21st century. Accordingly fa-mily principle of traditional Korean society, a senior of goodness, and filial thought as being Korean faith were explained. As one sees dishonor of leadership, a true picture of elderly and res-pectable aged person in needed. For problem areas, future plan for elderly welfare, support, and mandatory retirement age in Korea is suggested. As mean age of population is extend and elderly with specialty is growing, activity and life style of elderly need to be changed. Finally, for 'Neo-Elderly Model', harmony between old and young can be considered, and author suggested 10 life style for Neo-elderly.

The mental health of medical students deserves attention because the problems in students may negatively influence learning ability and create consequences for later adjustment to doctor s role. The purpose of this study is to understand the stress, copying, self-esteem and subjective general well-being of medical students and compare them with other students group (students of law, science and humanities). The results was as follows : First, medical students did not report more stress but they use less copying strategy than other students group. Second, there was no differences in stress, copying, self-esteem and general well-being between high and low academic achievement group in medical students. Futhermore, study-related stress had more close relationship with self-esteem, general well-being. Third, the preparatory course students showed lower score in general well-being, especially health, cheerful-depressive mood domain. These results imply that mental health promotion programmes focused in guiding adjustment for the preparatory course students are helpful. And psychiatric, academic counseling should be made available to them. It can lead to an improvement in our health care delivery system. The need of additional longitudinal research is discussed.

As a founding president of the Korean Association for Geriatric Psychiatry, I would like to look back on not only the quickening period of the association that was thirteen years ago but also on its early works and activities. This association was founded in 1994 in order to improve mental health of the aged in Korea and to help them live with dreams and ambitions. Starting with forty two members, the association has developed as one of the biggest associations, where approximately four hundred out of 2,221 psychiatrists in Korea are enrolled as regular members. In addition, it has made an eye-opening progress in terms of education, research and treatment. I hope that with the advent of an aged society, our association will play an influential role in helping the aged live creatively with hope and dignity by carrying out a psychogeriatric subspecialist system and by paying endless attention to their mental health.

Objective : Dementia is major neuropsychiatic disorder in the elderly. This study was aimed to investigate the prevalence of dementia and provide fundamental data for community mental health programs. Method : 500 elderly people aged 65 years and over in Kwachon were interviewed according to DSM-Ⅳ and examined MMSE-K, Korea-Dementia Rating Scale (K-DRS), Clinical Dementia Rating (CDR), Modified Hatchinski Ischemic Scale (MHIS) by trained research assistants. Results : Prevalence of dementia is 10.6% (Alzheimer type 8.0%;vascular type 2.6%). Old age, lower education, cardiovascular disease, head trauma and heavy smoking seem to be risk factors for developing dementia but sex difference is non significant. Conclusion : The results showed similar prevalence rates compared to other epidemiological studies. Demented group showed more cognitive disturbances than non-demented one. For patients of dementia, appropriate treatment and management by family members, other caregivers and mental health professionals are needed.

The population of the elderly and neuropsychiatric elderly patients increases radically, but realistic management in the welfare and medical dimensions are not adequate. Especially, the treatment and care for the neuropsychiatric geriatric patients have not been achieved properly for the lack of good medical facilities and heavy economic burden. Therefore, this paper will propose a model of specialized neuropsychiatric geriatric hospital suited to our reality for the welfare of the elderly themselves and their families. For this, we investigated the needs of medical consumers through surveys. Our subjects are 41 families of neuropsychiatric elderly patients in admission and 51 caregivers. In these surveys, patrons expect the establishment of specialized geriatric hospital proper to the characteristics of neuropsychiatric elderly patients. In addition, they hope patients adminssion fee to be reduced as difficulty and specialty of neuropsychiatric geriatric patient treatment are actively applied to the medical insurance fee and national support system. According to our examination of the caregeivers for the neuropsychiatric elderly patients, caregivers didn't receive systematized training, but only brief care-giving education. Their status is also unstable and their pay is low. These issues are very important for the quality of care-giving work. Therefore, specialized neuropsychiatric geriatric hospitals should be established properly to our social reality and request, and national and social supports for the training and education of medical staffs and quite necessary.

Dementia has emerged as a major health challenge, not only for clinicians but for a society as a whole. The explosion of research aimed at exploring dementia in the past 20 years has produced a great deal of knowledge concerning not only Alzheimer's disease but also other conditions referred to non-Alzheimer's diseases. Recently the advance of neuroimaging, neuropsychology, and molecular genetics has offered our best hope to trace the causal chain about Alzheimer's and non-Alzheimer's disease. Our under-standing of the pathogenesis of dementia is improving, and new research will allow more effective preclinical screening of potential therapeutic compounds. The core of treatment of demented patients is psychiatric management, which must be based on a solid alliance with the patient and family and thorough psychiatric, neurological, and general medical evaluations of the nature and cause of the cognitive deficits and associated noncognitive symptoms. Dementia is often progressive and thus, treatment must evolve with time in order to address newly emerging issue. New medications will need to be incorporated with innovative psychoso-cial therapies and health system changes to improve the quality of life of patients and caregivers. Management inv-olves psychosocial and community resources as well. To date, the status of our management of demented patients is on the beginning stage. Ulti-mately, we will need to build a management model on demented patients as long-term coun-terplan.
