목적 : 급성하벽심근경색증 환자에서 심전도상 흔히 동반되는 전흉부유도 ST절 하강의 의의를 알아보았다. 방법 : 심근경색후 24시간에서 48시간에 얻은 심전도를 기준으로 52명의 급성하벽심근경색증 환자를 전흉부유도에서 ST절의 하강이 있는 군과 없는 군으로 나누었으며 심도자, 관상동맥조영술, 심초음파도 및 방사성 핵종을 이용한 좌심구혈율 측정 등을 시행하였다. 결과 : 1) 좌심실확장기말압은 전흉부유도에서 ST절의 하강이 있는 경우에서 16.9±5.33mmHg로 없는 경우의 11.0±4.02mmHg보다 유의하게 높았다(p<0.05). 그러나 운동량 및 좌심구혈을은 흥부 유도상 ST절의 하강이 있는 경우 7.6±3.0 METs 및 53.9±9.1%로 없는 경우의 9.1±2.7 METs 및 54.6±9.5%보다 낮았으나 통계적 유의성은 없었다(p=0.180, p=0.823). 2) 관상동맥조영술상 전흉부 ST절의 하강이 동반된 군에서는 유의한 좌전하행지나 좌회선지의 협착이 있는 경우가 60.9% 및 57.9%로 ST절의 하강이 없는 군에서의 34.5% 및 7.7%와 비교해 좌관상동맥에 협착이 동반된 경우가 많았다(p=0.050, p=0.001). 3) 관상동맥조영술상 세 혈관질환의 빈도는 흉부유도상 ST절의 하강을 보인 23예에서 10예로 ST절 하강이 없었던 29예중 2예에 비하여 유의하게 많았고(P=0.007), 단 혈관질환의 빈도는 ST절의 하강을 보인 군에서 23예중 5예로 ST절 하강이 없었던 29예중 17예에 비하여 유의하게 적었다(P=0.002). 두 혈관질환의 경우에는 각각 8예와 10예로 양군간에 유의한 차이가 없었다. 4) 흉부유도상 ST절 하강의 빈도는 단 혈관질환 22예 중 5예에서, 두 혈관질환 18예중 8예, 세 혈관질환 12예 중 10예에서 관찰되어 협착이 있는 관상동맥의 수가 많을수록 ST절의 하강이 나타나는 빈도가 많음을 보였다(p=0.00308). 그러나 흉부유도상 나타난 ST절의 하강을 모두 합하여 구한 ST절 하강의 합은 협착이 있는 관상동맥의 수와 통계적인 유의성이 없었다. 5) 심초음파도상 좌심실 하벽의 벽운동은 ST절 하강을 보인 군에서는 akinesia가 83.3%, hypokinesia가 11.1%, 정상 벽운동이 5.6%로, ST절 하강이 없었던 군에서의 dyskinesia가 3.6%, akinesia가 39.3%, hypokinesia가 25.0%, 정상 벽운동이 32.1%와 비교하여 ST절의 하강이 있는 군에서 유의하게 벽운동의 장애가 빈번함을 보였다(p=0.03891). 그러나 좌심실전벽, 측벽 및 중격부위에서는 유의한 벽운동의 차이가 없었다. 결론 : 급성하벽심근경색증 환자의 전흉부유도에서 ST절의 하강이 동반되는 경우 다혈관 질환의 가능성이 높으며 좌심실확장기말압이 상승되었고 운동능력은 감소되어 있었다. 또한 심초음파도상 좌심실하벽의 벽운동장애도 심하였다. 따라서 전흉부 ST절의 하강을 동반한 급성하벽심근경색증 환자는 전흉부유도에 ST절 하강이 없는 경우보다 예후가 불량할 것으로 생각되며, 보다 적극적인 치료가 필요할 것으로 생각된다. The purpose of this study was to determine the significance of precordial ST segment depression appearing during acute inferior myocardial infarction and to assess the correlation of that with angiographic finding. 52 patients were allocated into two groups based on the existence of precordial ST segment depression : 23 patients with ST segment depression and 29 patients without ST segment depression. The extent of coronary artery disease as well as the prevalence of significant stenosis (≥70%) in left anterior descending artery were more frequent in patients showing precordial ST segment depression than in patients not showing them (p=0.050) and the result were similar in cases of left circumplex artery (p=0.001). On echocrdiographic examination of left ventricular (LV) wall motion, it showed more severely decreased inferior LV wall motion in patients showing precordial ST segment depression than in patients not showing them (p=0.03891) even though the other segment of LV wall motion didn't show the statistical difference between both groups. The other cardiac parameters such as LVEDP, exercise amount (METs) and ejection fraction were tend to showing bad profile in patients with precordial ST segment depression. From the above results, we could deduce that patients with precordial ST segment depression have relatively large infarction or concomitant left coronary artery disease, so they need more caution and intensive theraphy.

A multiresidue method(MRM) for insecticides is an efficient way to screen a large number of samples for multiple pesticides in a relatively short time period. There are numerous MRMs testing for a single class of compounds such as organophophorus(OP), organochlorine(OC), n-methyl carbamate(MC) insecticides, but few screen for these insecticides with a single sample extraction. The main objective of the use of MRMs is to determine as many pesticides of different chemical structure as possible in various types of samples of known or more often of unknown origin in a single procedure. The proper application of MRMs requres knowledge of extractability of different compounds from various types of samples, the distribution properties in solvent systems of different polarity, elution patterns in column chromatographic systems, the loadability and selectivity of chromatographic separation and the specificity and sensitivity of detection. For the determination of pesticide residues such a multitude of methods has been described that a complete survey of literature is very difficult for the analyst. However, by far the majority of these methods consist of a few working steps such as extraction with a limited number of solvents, liquid-liquid partitioning, adsorbent column chromatography or gel permeation chromatography and the determination, mostly with GLC, TLC, or HPLC. For the various pesticides groups they differ only in some details (e.g. amount and activity of obsorbents, composition and polarity of solvent mixtures) selected according to the attributes of the residues to be analysed and the co-extractives to be separated. The objective of this paper is to give some guidance on the application of the various processes used in the general scheme of MRMs by comparing some well established methods covering a wide range of pesticides.

Using modified self-report questionaire composed by Dr. Oh, Dong Won and his associates(1986), the concept and attidtude of the schizophrenic outpatients toward antipsychotic medication was investigated. The subjects were 151 chronic schizoprhenic outpatients in Seoul National Mental Hospital during the time from July 1. to Aug 31., 1987. The significant results were as follows. 1) 80.2% of the subjects responded as "drug can help improve their illness" but only 45.6% of them reported to take drug voluntarily. 2) Regarding to the greatest benifits of antipsychotics, "to improve insomnia" was most popular response(53.2%). 3) The favored method of medication was "by oral"(97.2%), its frequency was "once a day in the evening"(50.0%) and the number of drugs taken was "less than 5 per day"(69.2%) 4) 79.9% of the subjects had some experiences of "unwillingness to take drugs" which was mainly accounted by "unpleasant side effects"(30.9%) 5) 48.2% of the subjects reported that antipsychotics might have "habituation potential" and 60.9% reported that antipsychotics would have "adverse effect on the body" 6) 61.5% of the subjects accepted the necessity of drug continuation ordered by doctor and the main reason of drug continuation was "to help treatment"(44.2%), while the main reason of drug discontinuation was "unnecessary because of being cured of disease"(50.0%) 7) It was reported that the most unpleasant side effect of antipsychotics was tremor, followed by sedation and constipation. 8) Demographic variables(ie ; duration of illness, number of previous admission, educataion) were compared in two groups using χ²-test. The statistically significant results were as follows. (1) The number of patients answering that they world take medication "voluntarily" and world take "more than 3yrs" was higher in the longterm patients. The number of patients answering that they are "dissatisfactory" on medication was higher for short-term patients. (2) The rate of "complete effectiveness" regarding to the concept on the value of antipsychotics was higher in the group who had less frequent number of previous admission. (3) The rate of "pharmacotherapy"(the proposed treatment method) was higher in the high education group.

The valve of the human being is evidenced historically by the physical strength rather than mental capability. But, it was not until the 1960's that an awakening to the real value of human capital actually occurred. Theodore W. Schultz observed the heterogeneity of capital and he caw that the human being was a form of capital which could be developed. Schultz's important contribution is the assertion that skills and knowledge are a form of capital. Education in one of the many elements which influence economic growth and it does in serveral ways. So, the purpose of this study was to consider the correlation between education and economic growth, to estimate educational contribution to the economic growth by preceding study. The conclusions of this study were as follows : 1. Education and economic development are a very close relationship. 2. Educational development is prerequiste and independent to economic development 3. Education directly anti indirectly contributes to economic growth. 4. So, Educational investment should be expanded to support educational development constantly.

When we classily the supervisory patterns as traditional scientific management, human relations, and neoscientific management, these days, supervisory practices in schools are based on one, or a combination, of three general supervisory theories. Traditional scientific management represents the classical autocratic philosophy of supervision in which teachers are viewed as appendages of management and such are hired to carry out prespecified dulies in accordance with the wishes of management. Human relations supervision has its origins in the democratic administration movement advocated in the 1930's and is still widely preached and practiced, and superrisor works to create a felling of satisfaction among teachers by showing interest in them as people. But, human relations supervision is still widely advocated and practiced today, though its support has diminished because of being delivered little. And, neoscientific management supervision is in large part a reaction against human relations supervision, but, it is impersonal, technical, rational control mechanisns. The three images of supervision share a lack of faith and trust in the teacher's ability and willingness to display much intermit in the welfare of the school and its educational programs, and these three images of supervision are judged inadeguate as models to meet present conditions. Se, the purpose of this study was to consider the features, and the grope the fature's views of new approach of human resources supervision that views people as having the potentiality, the desire and potential for motivation, responsibility, sucess at work and is based on the McGregor's Y theory. The features of the human resources supervision in different from that of the human relations supervision. Whereas human relations and human resources supervision are both concerned with teacher's satisfaction, human relations views satisfaction as a means to a smoother and more effective school. The human resources supervisor, by contrast, views satisfaction as a desirable and toward which to teachers win work, and it suggests that designated group leaders (teaches, chairpersons, supervisors, consultants, principals, and so on) come to conceive of their role primarly as one of providing service rather than direction to the group, and human resources supervision work to help the group accomplish its tasks, on believing the ability of group members. In this point, human resources supervision in not only humane and fitting for educational organizations with their people intensive characteristics and distinctively human undertakings but that this view is supported by a formidable body of theory and research and enjoys claims of success from practitioners in many fields. But, human resources supervision is not an elixir to be administered indiscriminately to all. It is a powerful conception of supervision that, by using a concepts of motivation and job enrichment, can markedly improve the identity, commitment, and performance of most teachers and the effectiveness of schools.

The hazard factors in building construction project are various and their bad effects with regard to project's efficiency are increasing due to its enlargement and complexity. However. the assessment of the construction safety is commonly dependent upon the statistical and historical information. since the existing systematic tool assisting to the effective decision making for estimating the safety prior to construction phase is inaccurate. In addition. it is true that there are the various difficulties to analyze and diagnosis the construction safety with the probabilistic approach. because there are the many vague factors and limited resources. Therefore. the purpose of this research is to provide the way to establish the efficient preventable countermeasure against the hazard factors. corresponding to the category of the hazard characteristic. by using non-structural fuzzy decision support system for diagnosing effectively the construction project safety.
