목 적 : 정 신분열병 환자의 자기만입 정도에 영향을 미치는 인구학적 변인들 및 질병연관 변인들을 규명해 보고자 하였다. 또한. 환자들의 자기만입과 병식 사이의 연관성. 자기만입과 자존심 사이의 연관성을 알아보고자 하였다. 방 법 : 정신과 의사가 병록지와 면담을 통하여 대상 정신분열병 환자들의 인구학적 변인들 및 질병연관 변인들에 관한 자료를 얻고 환자들의 병식 정도를 평가한 후, 환자들로 하여금 자기보고형의 자기만입 척도와 자존심 척도를 시행하게 하였다. 총 111명의 환자가 연구대상으로 선택되었다. 결과: . 1) 여자가 남자보다 유의하게 높은 자기만입 척도 점수를 나타내었다 2) 질병연관 변인들 중 하위집단 사이에 자기만입 척도 점수의 유의한 차이를 보이는 변은 없었다. 3) 자기만입 척도 점수와 병식 점수 사이에 유의한 상관관계가 없었다. 4) 자기만입 척도 점수와 자존심 척도 점수 사이에 유의한 역상관 관계를 보였다. 결 론 : 본 예비 연구의 결과로 보아 정신분열 병 환자의 병식이 부족한 상태에서도 자기만입이 진행될 수 있으며. 자기만입이 심할수록 환자의 자존심이 저하되는 것으로 생각된다. 또한 여자 환자들이 남자 환자들보다 자기만입에 더 취약한 것으로 생각된다. 따라서 정신분열 병 환자의 이해와 치료를 위하여 자기만입에 관한 지속적인 연구가 필요할 것으로 생각된다. objective : This study was conducted to identify demographic variables and illness related variables which may affect the severity of self-engulfment in the patients with schizophrenia. We also studied the relationship between self-engulfment and insight, and the relationship between self-engulfment and self-esteem. Methods : Data on demographic variables and illness related variables for the subjects were gathered from hospital records and clinical interviews by the psychiatrists. Degree of insight for the subjects was assessed through clinical interviews by the psychiatrists. Degree of self-engulfment and self-esteem for the subjects was assessed from the self-engulfment scale and the self-esteem scale respectively. A total of 111 patients with schizophrenia were selected for statistical analysis. Results 1) The females exhibited significantly higher scores than the males on the self-engulfment scale. 2) There was no illness related variable, which exhibited a significant difference among subgroups on the self-engulfment scale. 3) There was no significant correlation between the self-engulfment scores and the insight 4) There was a significantly inverse correlation between the self-engulfment scores and the self-esteem scores. Conclusion : The results of this preliminary study suggest that self-engulfment may develop despite lack of insight and that there was inverse relationship between self-engulfment and self-esteem in the patients with schizophrenia. It also suggests that females are more subject to self-engulfment than males. So, authors suggest that it is valuable to do further studies of self-engulfment in the patients with schizophrenia.

Morphological studies on larval hemocytes of varioius insects were performed in two ways of research. Ⅰ. Finestructures. An electron microscopical study on hemocytes of last instar larvae of 12 species of Lepidoptera was performed to observe cell types, structrues, raions, relationships and their origins. The results are as follows; 1) Prohemocytes are the smallest round cells with large numlesus, poorly developed cytoplasmic organelles and lower composition ratio, accounting for less than 5% of all cell types. Little remarked differences were revealed among prohemocytes of varous insects and they are thought to be the origins of other cell types. 2) Palsmatocytes are relatively large cells with higher composition ration, accounting for about 40%. They could be subdivided into two forms, oval and spindle. Oval cells are rich in cytoplasmic projections and organelles. But the spindle cells include few of them, while nearly all of the spindle cells possess some microtubules as their cytoskeletons. Some marked difference were revealed among different insects. The most exceptional structure was the fibrous bundles located in both nucleus and cytoplasm in Sericinus telamon Donovan. 3) Granular cells are characterized by various granules in cytoplasm, and by higher composition ration, accounting for about 50% of all numbers. They could be subdivided into three forms, oval, round and spindle with fully developed cytoplasmic organelles and Projections. Cellular fractions were often noticed to be enclosed by granular cells, indicating some activities of phagocytosis. Granular cells are the most pleomo rphous of all cell types, and the most exceptional structures are the bundles of microfibrils in Phalerodonta manleyi Leech. 4) Adipohemocyte were found only in Plodia interpunctella Hubner. They are somewhat oval with few cytoplamic projections and less developed organelles. Some granular cells were found to accumulate lipid droplets into the cytoplasm by trapping floating lipid droplets, adn the adipohemocytes are believed to be originated from formers. 5) Sperule cells were found nearly in all specimens and characterized by sperules composed of flocculent materials. They are round or oval with few cytoplasmic organelles. The most conspicuous spherulesof all sperule cells were radial arrangement of sperules in Adristyrannus amurensis Staudinger and presence of the specific granules in Mamestra illoba Butler. Young sperule cells resembled the granular cells and it is possible that they originate from granular cells. 6) Oenocytoids are large cells and were found nearly in all specimens. They could be subdivided into 3 types according to their inclusions, such as microfibrils, microtubules and none of them. Young Oenocytoids resemble the giant plasmatocytes, perhaps in dicating to be originated from the latters. Ⅱ. Composition ratios of cell types from mid 5-instar to late prepupa. Composition ratios of cell types were investigated in phalerodonta manley; Leech and could be summarized as follows; 1) Prohemocytes disappeared from the stage of early prepupa. 2) Plasmatocytes increased in number at mid stages of each inster and decreased nearing to pupal stage. 3) Granular cells reached peak at early prepupal stage. 4) Adipohemocytes heavily increased at late prepupal stage. 5) Sperule cells increased at late stage of each instar and reached peak at late prepupal stage. 6) Oenocytoids increased at late stage of each instar and reached peak at early prepupal stage.

In this paper, the way that input voltage and input line current as a control variable is provided as one unit is projected. Till now, have dealed with three phase balanced load. But, in that case, total power factor compensation is difficult, for to control each phase at unbalanced load. Therefore, in this paper suggest of the scheme that three phase unbalanced load is controlled by each phase and input total power factor is compensated unit input factor. Therefore, in this paper suggest that three phase unbalanced load is controlled and the method in compensation of unit input factor to be attended by unbalanced load. Besides, the object of control is calculating quantity for input voltage and input line current for the point at issues make to improve of control method at unbalanced load. As a result, control system of each phase could maintain as unit input total power factor has been state diviation error of 2% with unbalanced load.

안봉영,김영주,김영길,이승석 한국비파괴검사학회 2000 한국비파괴검사학회지 Vol.20 No.1

석유화학 설비 등과 같은 노출 배관의 결함을 검출하는데 효율적으로 이용될 수 있는 자왜형 초음파 센서를 제작하였다. 최대의 초음파 발생 효율을 얻기 위한 최적 조건을 설정하였으며, 실험에 사용된 배관의 경우 250~350Oe의 정자기장이 최적이었으며, 180kHz의 주파수를 갖는 초음파를 발생시키기 위해서는 15mm 폭의 코일을 사용하는 것이 가장 좋았다. 최적의 조건에서 발생된 초음파는 50m 이상을 충분히 진행할 수 있으며, 결함의 단면적이 증가함에 따라 수신된 결함 신호는 직선적으로 증가함을 확인하였다. Magnetostrictive sensors which can be used effectively to detect flaws in pipe were fabricated. The optimal conditions to obtain the maximum generation efficiency of the ultrasonic wave were established. In case of the used steel pipe the optimal magnetic field was 250~350Oe and the coil width of 15mm showed the best efficiency for generating a wave with the frequency of 180 kHz. In the best condition, the wave can propagate further than 50m without serious attenuation. The amplitude of the ultrasonic wave reflected from artificial flaw had a good linear relationship to the cross-sectional area of the flaw.

This study was carried out for the purpose of knowing the effect from anti-allergic action of B cells and the IC-2 mast cells the extraction from Xanthii Fructus(EXF). In order to know the effect of the cytotoxicity from extraction of Xanthii Fructus, we had to examine the safe density of EXF on lung fibroblast cells of the mouse (mLPCs). We also attempted to resolve the relationship cytotoxicity. The effect was on the organization of cytokine gene expression from the increas and divorce of the B cells and allergic acting by EXF, we found it necessary to examine the IC-2 cells and B cells. We examined the histamine release of IC-2 cells by ELISA method, we also examined the effect of EXF on the increase and divorce of the B cells by ^3H-thymidine uptake method. We then analyzed the release of IL-4, IgE and nitric oxide (NO). The results are as follows : 1. EXF did not show cytotoxicity against mLFCs. 2. According to the inspection on the effect on IC-2 cells gene expression by EXF, we found out the following results: EXF reduced IL-4, IL-6, GM-CSF, TNF-α gene expression and histamine release of IC-2 cells. The EXF inhibited signs of inflammation IC-2 cells.
