This study aimed at an evaluation of the reliability and validity of Ewha Defense Mechanism Test(EDMT) for standardization during the period from June 25 to July 10 with nationalwide sample which was standardized by Rhee Kun Hoo. Kin Jae Un. Kim Jung Kyu. and Park Young Sook. The number of subjects were 1.323 who were sampled by the method of proportional stratification on age. sex. education. local area variables. This test is composed of 20 defense mechanism subscales and total items of the test are 200. The results were as follows : 1) The range of means of each scales were from 2.70 to 3.34 and the range of items standard deviation was from .71 to 1.28. 2) The corrected item-total correlation coefficients were than .10 for all items except two items which was the index of internal consistancy. 3) The spearman-Brown split-half reliability coefficients were more than .66 and the retest reliability coefficients were more than .72 for all scales. 4) By the evaluation of the cross validation with “16 Personality Factor Inventory”. it was found that 11 factors were consistent with expectation among 16 factors so that the result of cross validity was moderately sufficient. 5) By the factor analysis. four factors were extracted. Factor 1 was “unstable sensitization defense mechanisms”which were acting out, displacement, somatization. dissociation. projection. and passive-aggressive behavior. Factor 2 was “ego-expansive defense mechanisms” which were composed of controlling. distortion. altruism. humor. and sublimation. Factor 3 was “ego-denial defense mechanisms” which were reaction formation. bragging identification. and regressin. Factor 4 was “reality evasive defense mechanisms” which were denial rationalization. suppression. anticipation. and evasion.

營農類型別 農業所得의 隔差要因分析 : 河東部 3 個 部落을 중심으로 A Survey of Three Villages in Hadong-gun

金永暾,金厚根 慶尙大學校 1985 論文集 Vol.24 No.2

The present study has been performed postulating that we are able to increase income in a limited area of crop land by improving the type of farming and making use of family labor time. In an attempt to test the my hypothesis, three typical villages with the similar farm size but different type of farming have been selected. The results obtained in the survey are summarized as follows. 1) There are no differences between the size of crop land and numbers of farmers in the selected three villages. In addition, the farms have similar economic background and farming conditions. 2) Though the general food grain village still keep growing only rice and barley with the traditional type of farming, the other farms(villages) have changed to livestock farm by importing beef cattles since 1970. Improving the old style of farming the present major portion of job was livestock farming and minor, crop farming. Further a third type of farming, has been observed that have improved the old type of farming by employing both the multi-culture farming system and vinyl house. .3) Food grain village farmers cultivate rice and barley. But livestock farm village grow the rice and forage crops. Advanced horticulture farming farmer cultivate rice and horticulture instead of cultivating barley in the winter and spring season. 4) The cropping systems on non-paddy land in food grain village are crops and barley but livestock farmers produce mainly forage during the seasons. Vinyl house farmers regard horticulture farming as their main income source but summer crops only their family requirements. 5) It was found that the size of crop land surveyed on the three villages appeared similar in each other, but its labor input was shown to be remarkly different by their type of farming. The average labor input an livestock village and those an vinyl house farmer have been increased 60 percent and 70 percent, respectively, comapring with food grain village. 6) The ratio of fixed capital turned out to be the highest in livestock village. 7) The component-ratio of farm expenses is very different. In crop-major the component ratio of farm expenses shows the high figure of 44. 1 percent. It shows the lower in the other villages. 8) The farms with similar size of crop land but being improved in type of farming brought about a great differences in average farm income.. The average income of 350,000 Won in food grain village have been in comparison with that of 870,000 Won in livestock village and that of 760,000 Won in vinyl house village. 9) The factors of increasing farm income prove to be as follows. 1. To cultivate economic crops. 2. To use more labor hour. 3. Utilization of by-products. 4. To promote efficiency of land utility, such as 168 percent in food grain village, 180 percent in livestock village, 360 percent in vinyl house village. 10) From the result of determinant for increasing farm income by type of farming, crop land is measured as a critical factor of increasing farm income at the food grain village, and farm land, farm labor hours and other capital inputs have equally contributed to increase farm income at livestock village. Farm labor hours is measured as a important factor to improve farm income at the vinyl house village.

김종인,박종영,이병후,김현중,노정관,공영토 한국목재공학회 2002 목재공학 Vol.30 No.2

본 연구에서는 MDF와 잣나무 판재에 대한 난연처리 및 난연도장 처리 시험편에 대한 난연 효과에 대해 고찰하였다. 무처리 MDF와 잣나무판재에 대한 tdθ은 각각 279.5, 182.5로 나타났으나 난연침지 처리된 무늬단판을 오버레이한 MDF를 난연도장 처리 한 경우 높은 난연성능을 나타냈다. 난연처리한 잣나무판재에 난연도장처리를 할 경우 tdθ가 90으로 나타났고, 난연침지 처리 된 무늬단판이 오버레이 된 MDF에 난연도장처리 한 경우에는 tdθ가 0으로 나타난 가장 뛰어난 난연성능을 나타냈다. 전체적으로 난연처리 및 난연도장처리를 한 경우 tdθ가 감소하는 것으로 나타나 난연성능이 개선되는 것으로 나타났다. 또한 연소도 시험결과 시험편의 중량감소율은 난연처리와 난연도장처리에 의해 감소함으로써 난연성능이 개선되는 것으로 나타났다. 또한 착화시간과 잔염시간의 측정결과도 유사하게 나타났으며 난연침지 처리 된 무늬단판이 오퍼레이 된 MDF 및 난연처리된 잣나무판재에 난연도장 처리한 경우 무처리된 경우에 비해 착화시간은 증가되고, 잔염시간은 감소하는 것으로 나타났다. In this study, two materials treated with a flame retardant were examined for their fire resistance. The first, MDF(medium density fiberboard) was overlaid by an oak sliced veneer, which was either treated by soaking in a 6wt.% solution of flame retardant chemicals (pentabromine-chlorinated paraffin) or non-treated and then was coated with either a flame retardant polyurethane coating or with a common polyurethane coating. The second material, Pinus koraiensis penal was either treated by a spray treatment using a flame retardant solution or non-treated and then was coated with either a flame retardant polyurethane coating or with a common polyurethane coating. Pentabromine-chorinated paraffin chemicals were added (6 part of urethane resin) as the flame retardant chemicals in the polyurethane coatings. In the fire resistance test, the tdθ(℃·min.) decreased with the flame retardant treatment or/and the flame retardant coatings, compared to the untreated sample. Weight loss (%) decreased with the flame retardant treatment or/and the flame retardant coatings. The ignition time (sec.) increased and the residual flame time (sec.) decreased with the flame retardant treatment or/and flame retardant coatings. Therefore, the flame retardant treatment or/and flame retardant polyurethane coatings have excellent incombustibility.

목적 : 고관절 전치환 수술시 소위 ‘최소절개술’을 이용한 수술법이 여러가지 장점을 가지고 있다고 알려져 있다. 연부 조직의 외상을 줄이고, 수술 시 출혈양을 줄일 수 있으며, 수술 후 통증, 입원기간을 줄일 수 있다. 수술 후 회복을 빠르게 하고 미용상 수술 창상을 줄일 수 있다. 이 논문에서는 최소절개술과 표준절개술을 이용한 고관절 전치환술에서 수술적 측정요소와 삽입물 위치와 안전성의 차이를 전향적으로 비교연구 하였다. 방법 : 60명의 환자 79예에서 표준절개술(절개길이 12~15cm)로, 58명의 환자 78예에서 최소절개술(10cm 이하)로 일차 고관절 전치환술을 시행하였다. 두 군에서 모두 후외측 도달법으로 시행하였다. 결과 : 수술 중 출혈양, 헤모백 배출량, 입원기간, 주합병증의 비율, 방사선학적 측정요소 등 두 군간의 의미있는 차이가 없었다(p>0.05). 이에 비해 평균 수술시간, 헤모백 유지기간은 최소절개군에서 의미있게 짧았다(p>0.05). 또한 입원기간 중 평군 수혈량도 최소절개 군에서 의미있게 적었다.(p>0.05). 피부 절개의 연장은 최소절개군에서 의미있게 높았다(p>0.001). 결론 : 두 군사이에 대부분의 측정요서에서 차이가 없었지만, 환자의 대부분은 작은 수술창상을 선호하였다. 따라서 인공관절 삽입물의 위치, 피부와 연부조직의 치유에 문제가 없다면 최소절개술을 시행하는 것이 좋을 것으로 제의한다.

김영기,박정후 부산대학교 생산기술연구소 2000 生産技術硏究所論文集 Vol.59 No.-

플라즈마 디스플레이 패널(Plasma Display Panels, PDP)에서 투명전극으로 사용되고 있는 ITO 박막을 불평형 마그네트론 스파트링법으로 제작하여 그 공정 변수에 따른 ITO 박막의 전기적 · 광학적 특성 변화를 고찰하였다. 기판에 인가한 bias 전압에 따른 ITO 박막의 면저항 및 광투과율은 bias 전압 -20V에서 -30V인 경우가 가장 우수하게 나타났으며 ITO 박막의 특성을 결정하는 결정성장방향은 (400)방향이 지배적인 것으로 나타났다 ITO thin fi1ms, as transparent electrodes in ac-PDP, should have low resistivity and high transparency. In this study, ITO thin films have been deposited on glass substrates using rf unbalanced magnetron sputtering(UBMS) with an oxide target(90wt.%In2O3-l0wt.%SnO2) as a parameter of substrate bias voltage. ITO films prepared by unbalanced magnetron sputtering were characterized by electrical resistivity, optical transmission, X-ray diffraction Films with low sheet resistances(Rs=16Ω at film thicknesses of 2000Å) and high visible transmission(~90%) have been achieved by -20[V]~ -30[V] of substrate bias voltages. Also, films with (400) plane have low sheet resistances.

김성걸,김주영,정호동,김재호 한국공작기계학회 2009 한국공작기계학회 춘계학술대회논문집 Vol.2009 No.-

This paper describes in detail the life prediction models, and simulation of thermal fatigue under different mold compounds and chip sizes for wafer level embedded SiP. A 3D Finite element model was built to simulate the viscoplastic behaviors for mold compounds and chip sizes. Especially, bonding parts between mold and Silicon Nitride(Si₃N₄) were carefully modelled and distribution of strains was studied. Three different chip sizes were used and the effects of mold compounds were observed. Consequently, this numerical study shows that type-A has better fatigue life than other mold compounds. Also, 4×4 size chip has a shorter life than 6×6 and 8×8 size.

The object of this paper is to evaluate the relationsip of the mothers' Psychopathological characteristics with their children's schizophrenic morbidity. Psychopathological characteristics of the cases were measured by SCL-90-R. Above mentioned relationship was tested by the difference between SCL-90-R scales of 77 cases of the mothers of the in-and out-patients of the National Seoul Mental Hospital and the SCL-90-R scales of normal control group. The results of the test are as follows; 1) Total schizophrenic mothers, as compared with the control, showed significantly higher scores on hostility, psychoticism, depression, and anxiety. On the contrary, the normal mothers shcwed higher score on somatization than the schizophrenec mothers group. 2) Female schizophrenic mothers showed higher scores on hostility, anxiety, and paranoid ideation than the male schizophrenic mothers group. 3) Female schizophrenic mothers showed higher scores on hostility, psychoticism, anxiety, depression and phobic-anxiety than the control group. However, male schizophrenic mothers showed significantly higher scores on depression and psychoticism than the control group.

김영삼,박중후 漢陽大學校 工學技術硏究所 2002 工學技術論文集 Vol.11 No.-

본 논문에서는 기존의 DS-CDMA 시스템의 성능분석을 위해 사용되는 표준 가우시안 근사법(Standard Gaussian Approximation)을 이용하여 3세대 이동통신 시스템인 WCDMA(Wideband Code Division Multiple Access) 시스템의 상향링크에 대한 성능을 분석하였다. 수신된 신호의 신호대 잡음비를 이용하여 시스템의 성능을 분석하는 표준 가우시안 근사법을 사용하여 대역이 제한되지 않은 경우와 대역이 제한된 경우에 대하여 각각 성능을 분석하고 백색 가우시안 채널을 가진 다중 사용자 간섭 상황하에서 모의실험을 실시하였다. 모의실험 결과를 통해 표준 가우시안 근사법을 이용한 WCDMA 시스템의 성능 분석이 타당함을 확인할 수 있었다. In this paper, the performance of uplink WCDMA systems was analyzed using the SGA(Standard Gaussian Approximation) method which is used for the performance analysis in conventional DS-CDMA systems. The system performance for the bandlimited case and the case having infinite bandwidth was analyzed using the SGA method and simulation were performed in an AWGN channel. It was shown that the SGA method can be used for analyzing the performance of uplink WCDMA system through simulation results.
