Data from 3.982 adults participating in a health examination in a university hospital were analysed to determine the reference values of hyperlipidemia and hypolipidemia, and those were compared with American data. Also health related behaviors affecting hypocholesterolemia were investigated. 29.3% of the males diseased subjects, and as were 25.6% of the females in their twenties, 69.5% of the males in their 60s and 78.6% of the females in their 50s. The rate of diseased subjects tended increase with increasing age. The rates of the diseased were 60.1% for males and 55.2% for females. Among cardiovascular risk factors, the proportion of hyperlipidemia was 46.6%, fat liver 42.2%, hypertension 21.8%, glucose intolerance 13.7%, abnormal EKG 11. 0%, obesity 2.9% and anemia 1.7% for male subjects and hyperlipidemia was 31.2%, fat liver 29. 5%, anemia 27.5%, hypertension 21.1%, abnormal EKG 15.7%, obesity 7.3% for females in that order. The rates of cardiovascular risk factors were higher in males than in females except for anemia, abnormal EKG and obesity. The total cholesterol levels of 95 percentile for males and females were 227.0 mgldl, 226.0 mg/dl and the 5 percentile levels for males and females were 134.0 rag/dl, 131.0 mgldl, respectively. The LDL cholesterol level of 95 percentile for males and females were 150.0 mg/dl, 147.0 mgldl, and the 5 percentile were 53.0 mgldl, 51.0 mg/dl, respectively. The HDL cholesterol 95 percentile levels for males and females were 82.0 mg/dl, 83. 0 mg/dl, and those of 5 percentile were 36.0 mg/dl and 39.0 mg/dl, respectively. These data show that the mean levels of total cholesterol, triglyceride, LDL cholesterol were related to increased age in both sexes, and were slightly higher in the females than in the males over all ages, but those of HDL cholesterol decreased. The high cholesterol level group was associated with age, the amount of alcohol consumption, smoking and body mass index. But that was not associated with meat intake and regular exercise. No significant difference were found among the rates of all diseases except for diseases and anemia up to 160 mg/dl of cholesterol level in both sexes. Sex, regular exercise and glucose intolerance were revealed as influencing factors in the low serum cholesterol levels, but disease and abnormal EKG had a lowing effect for the low cholesterol risks. In conclusion, the reference values of Korean serum lipids were 5-25 mg/dl lower than Americans. The cut-off value to diagnosis hypolipidemia for the Korean is recommended as below 140 mg/dl of serum total cholesterol. The hyperlipidemia cut-off value should above 220 mg/dl of serum total cholesterol.

The aim of this study was to evaluate exposure to dust and endotoxin produced while working at swine confinement buildings. The dusts and endotoxin may cause adverse health effects on humans. Fourteen swine farms located at Yong-In, I-Cheon and Yeo-Ju of onggi-do were investigated. Husbandry workers form the farms were requested to wear personal sampler to measure respirable dust levels. Area samplings for total and respirable dust were also conducted at swine confinements buildings by season (summer under window open, winter under window close.) Gravimetric analyses and Limulus Amebocyte Lysate assay for measu- rement of dust level and endotoxin, respectively. The highest geometric mean (GM) concentration of airbome dusts was 7.47mg/㎡ for area respirable dust. and 10.35mg/㎡ for personal respirable dust. For respirable dust levels, seven farmers exceeded level of ACGIH, 3mg/㎥. The highest GM of endo- toxin was 5745.40 EU/㎥ for personal respirable dust. Significantly increased level of total dust (p〈0.001) and endotoxin in area total dust was observe with winter samples compared with those of summer. Area total dust and area respirable dust (r-0.622, p〈0.0001) was very significantly correlated in winter. Swine husbandry worker may have a considerable risk of ill health whenexposed to level of dust or endotoxin demonstrated at this study.

With the increased use of lasers in industrial welding applications, techniques for monitoring and controlling these processes become increasingly important. It is very important that we understand the dynamic behaviors of the laser induced plume in welding because the laser induced plume has considerable effects on welding efficiency and the quality of materials. As the plume fluctuation was associated with keyhole instability, unstable vapor plume indicated the process was unstable and would result in poor welds. An Infrared Themal-vision Camera can be utilized compensate for incurracies encountered in real-time monitoring during laser welding. We have results that instabilities of plume are closely dated with hot cracking and defect of laser welding.

The purpose of this study was to investigate the change of related factors in cardiovascular function variables after long duration regular exercise programs. The subjects of this study were 40 older man and women residing Seoul-Seniors-Tower. All of subjects divided to four groups, exercise group 20(man = 10, women = 10) was participating in an exercise program for 3 years, and the other group or non-exercise group 20(man = 10, women = 10) was not in that program. In the results, Changes of cardiovascular function were significantly improved in peak oxygen uptake, ventilation, rest blood pressure of cardiovascular function variables in male or female exercise groups after 3 years' exercise program. Also, we have been known to the facts that although the cardiopulmonary variables of men are superior to those of women, if being exercised for a long time, the women's cardiopulmonary variables(e.g. Endurance time, HRrest, SBPrest, SBPmax, DBPrest, RPPrest, and RPPmax) would not different from those of the men especially in old ages. As a conclusion, we could know that not only the regular exercise might increase or change almost the cardiovascular function variables except for V ˙O2max, Ventilation, and HRmax of elderly people, but also the sex's differences were vanished in endurance time, HRrest, SBPrest, SBPmax, DBPrest, RPPrest and RPPmax between males and females. Therefore, we might tell that exercise programs could provide an excellent parameters for enforcing or keeping the cardiovascular functions of elderly people.

발달장애학생을 위한 웹기반 의사소통능력신장 프로그램의 개발과 적용 사례

김동현,유영환,김좌중,천경철,이청용,김봉수 국립특수교육원 2005 연구보고서 Vol.- No.10

발달장애학생의 의사소통능력은 단순한 언어문제 이상의 의미를 지닌다. 의사소통능력은 모든 학습의 기초가 되고 결국 인간의 삶의 질을 좌우하게 하는 중요한 요소가 되고 있기 때문에 의사소통능력에 문제가 많은 발달장애학생에게 있어서 의사소통능력 신장은 매우 중요하다. 발달장애학생의 언어 및 의사소통능력의 결함은 사회적 결함과 인지적 결함에 상호 관련성이 있어 다른 사람으로부터의 의사소통을 이해하는 능력과 자신의 생각을 표현하는 능력이 제한되어 다른 사람과의 상호관계를 맺는데 어려움이 많았다. 따라서 발달장애학생의 언어지도는 생활 장면에서 교수하는 것이 가장 바람직하다고 하겠다. 그러나 지금까지 주로 활용된 전통적인 언어지도 방법은 어휘를 증가시키고, 발화의 길이를 널리는 데는 효과가 있었지만, 학습된 내용을 생활 장면에서의 일반화에는 문제점이 있는 것으로 지적되고 있다. 발달장애학생의 언어지도 방법은 일상생활 속에서 학습 내용을 선정하고 이를 실생활 장면 혹은 이와 유사한 환경에서 효과적으로 지도할 수 있는 적절한 교수 방법이 필요하다. 그래서 발달장애학생의 의사소통능력 신장을 위한 환경중심 언어지도 방법을 활용한 웹(Web)기반 언어지도 프로그램을 개발하였다. 웹(Web)기반 언어지도 프로그램은 제7차 특수학교 기본교육과정과 국립특수교육원에서 발간한 ‘발달장애학생의 언어교육 프로그램(1998)’ 분석을 통하여 개인 · 가정생활, 학교 · 사회생활, 경제 · 여가생활 등의 6개 영역으로 구분하여 각 영역별 학습주제를 선정하였으며, 학습주제에 대한 학습의 진행 형태는 학습목표, 낱말학습, 상황학습, 평가로 진행할 수 있도록 하였으나, 학습자의 현재 수행 능력을 고려하여 능력에 따른 진행의 절차를 학습자가 선택할 수 있게 하였다. 본 프로그램을 적용해본 결과 다음과 같은 교육적인 효과를 얻을 수 있었다. 첫째, 웹을 활용한 가상체험을 통하여 적극적이고 흥미 있는 참여를 유도하며, 학습자 중심의 주도적인 학습과 안내자, 촉진자로서의 교사의 역할을 통해 발달장애학생의 의사소통 능력을 신장시킬 수 있었다. 둘째, 교실에서 이루어지는 지금까지의 수업방식을 탈피하여 학습자가 언제, 어디서나, 누구든지 학습할 수 있는 열린 학습체제의 교육환경을 조성할 수 있었다. 셋째, 문자정보, 그래픽, 애니메이션, 사진, 음성, 비디오 등 다양한 형태의 정보가 상호대화 형식으로 활용되며, 수준별 반복학습을 실시함으로써 교수-학습 방법의 개선뿐만 아니라 양질의 수업을 진행하는데 도움을 줄 수 있었다. 본 프로그램을 활용한 언어지도가 발달장애학생의 의사소통능력 신장을 위한 최선의 방법이라고 말할 수는 없으며, 언어지도의 한 가지 방법이라고 말할 수 있다. 따라서 본 프로그램의 활용한 언어지도는 학교에서 교사가 학생의 능력과 흥미를 고려하여 지도한다면 발달장애 학생의 의사소통능력 신장에 많은 도움이 될 것이다. The developmental disability of the metal handicapped children means more than simple linguistic problem. The developmental disability is the base of all the learning and important factor which decides the happiness of the human being finally, so the extension of mutual understanding ability is so important, in the case of the metal handicapped children who have a problem of the mutual understanding ability. In the case of the metal handicapped children, the defects of the mutual understanding and linguistic ability are related with the social defect and the defect of recognition, and the ability of understanding about mutual relations with other people and self-expression ability are limited. So they have many problems in mutual relations with other people. Therefore, the linguistic instruction of the metal handicapped children is recommended to be done in the living. But, the traditional linguistic instruction which's used mainly as yet, is effective in increase of a vocabulary and the length of a locutionary act, but it has a problem in the popularization of the learning in the real life. The method of the linguistic instruction for the metal handicapped children, should be selected as contents in the real life, and the right learning method which can be done under the real life or the similar environment with it, is needed. Because of the above realities, the linguistic teaching web-based program is developed, using the linguistic instruction which is focused on the environment, for the extension of the mutual understanding ability of the metal handicapped children. In the linguistic teaching web-based program, it is divided with 6 field (personal · home life, school · social life, economical · leisure life) and the educational subject classified by each field is selected, by the analysis of 'The linguistic educational program for the children who have developmental disability' published by the 7th basic education course of special school and the national special education organization. Besides, the progress form of learning about the educational subject is directed by educational goal, word learning, situation learning and valuation, but a learner can choose a procedure followed by ability, regarding to his accomplishment ability. As the result of the application of this program, the educational effects that we could get are the following : 1. We could lead a positive and interesting participation by virtual experience through WEB, and the communication ability of the metal handicapped children was extended by a role of a teacher, as a guide and promoter and a leading learning focused on a learner. 2. The teaching method which is done in school now, is dismissed and we could form the educational environment of the learning system that a learner could learn, without distinction of time, a place and a person. 3. The various form of information, like text, graphic, animation, photo, sound, video and so on, is applied as a form of communication. Therefore, the program was useful in not only the improvement of the teaching-learning method, but also the proceeding of the effective lesson. The linguistic teaching which use this program, can not be the best method of the extension of the mutual understanding ability and it's just one method of linguistic teaching. if the linguistic teaching which use this program is conducted, regarding to a ability and a interest of a student, it will be so useful in the extension of the mutual understanding ability, for the children who have developmental disability.

To study the correlation between virulence and Congo red binding capacity of Shigella, 2 invasive strains of Shigella flexneri to HeLa cell were subjected to investigate the regulation of levels of membrane proteins mediated by Congo red. Two tested strains were pigmented on the agar plate containing Congo red. Virulent S. flexneri grown in the presence of Congo red at 37℃ showed increased levels of three proteins with molecular weight of 43,000, 58,000, 63,000 daltons in the sodium lauryl sarcosinate(SLS) soluble membrane fractions and those proteins were also found in the total membrane fractions. But those proteins were not found in the SLS insoluble fractions. At 32℃ or 42℃, the protein levels in the SLS soluble fractions or SLS insoluble fractions unaffected by the presence of Congo red. The expression of these proteins was dependent to the incubation temperature.
