This study is to examine how survivors' perceived variables concerning layoff affects organizational effectiveness, and this study has the following major objectives. 1. To examine how perception of survivors about layoff(perceived justice, perceived co-workers' reactions, perceived identity feelings with layoff victims, perceived job insecurity) would affects in job satisfaction and organizational commitment. 2. To find if survivors' perception of concerning layoff affects the change of job satisfaction and organizational commitment, demographic factors will operate as moderate variables. To examine the above objectives, empirical study is conducted: seven companies were selected as samples for this study and 743 questionnaires were analysed. The findings show that job satisfaction and organizational commitment decreased after layoff. The perceived of co-workers reactions influence job satisfaction and organizational commitment. The perceived of identity with layoff victims negatively influence job organizational commitment. The relations between perceived job insecurity and job satisfaction and organizational commitment are not significantly correlated. The moderating effects of demographic variables were found in union membership, and marital status. Finally, the implications of this study are that employees' job satisfaction and organizational commitment as job attitude variables are decreased after layoffs. Therefore, human resources manager are required to consider the survivor's perception and try to maintain their psychological stability in jobs. Perceived justice of layoff has a positive influence on organizational effectiveness, do personnel manager should consider the procedural and distributive justice about layoff.

This study is on the development of a monitoring system which can be applied for not only large vessels but also small vessels less than 20 gross tonnage. The Monitoring system consists of many LMU(Local Monitoring Unit)s that collect data from local machinery, a host computer that controls LMU and a stable communication system. In this paper, the industrial computer is used as host computer and that is compotable to IBM PC. GUI(Graphic User Interface) for main program is constructed by the use of HANGUL library and BOLAND C??, so this software package is easy to access to beginners. The LMU is made up from 80C196KC, which consists of CPU, interface, digital input/output, analog input/output and communication. Communication system between the host computer and LMUs is the multidrop configuration using RS-485 method. One master device of industrial computer has the role of host computer and LMUs acts as slave devices. And, more efficient communication system is practicable by the aid of polling method as well as carrier sense multiple access with collision detection(CSMA/CD) protocol.

본 연구는 Brown과 Leigh가 개발한 Adaptive Behavior Inventory(ABI)의 한국판 표준화를 위한 예비연구로서, 본 검사의 신뢰도와 타당도를 검증함으로써 그 유용성을 입증하고자 하였다. 정신지체학생 124명과 정상학생 82명을 대상으로 교사로 하여금 5개 하위척도(자조능력, 의사소통능력, 사회능력, 학업능력, 작업능력)에 4점 척도로 평정하도록 하였다. 신뢰도를 알아보기 위하여 먼저 내적 일치도(Cronbach' α)를 산출하였는데, 정신지체집단에서는 .85~.93이었고, 정상집단에서는 .89~.94로 모두 통계적으로 유의미하였다(p<.05). 검사-재검사는 정신지체집단에서 .88~.91이었고, 정상집단에서 .88~.92로 모두 통계적으로 유의미하였다(p<.01). 한편, 교사의 전문적 판단과 각 하위척도와의 준거관련타당도는 정신지체집단에서 .71~.78이었고, 정상집단에서 .72~.81로 나타나 비교적 높은 정적 상관을 보였으며, 사회성숙도와 각 하위척도와의 피어슨 적률상관계수는 정신지체집단에서 .39~.47이었고, 정상집단에서 .38~.45로 만족할만한 수준으로 나타났다. 또 구성타당도는 각 하위척도들간의 상호상관계수가 정신지체집단에서 .51~.75이었고, 정상집단에서 .61~.80으로 나타나 모두 통계적으로 유의미하였다(p<.05). 본 연구에서 나타난 결과를 종합해 볼 때, 이 적응행동검사는 정신지체집단과 정상집단 모두의 적응행동을 평가할 수 있는 유용한 도구가 될 수 있음을 시사해 준다. This study was preliminarily executed to develop the Korean Version of ABI(Adaptive Behavior Inventory) for identifying the abilities of self-help, communication, social interaction, academic tasks, and occupation tasks.Subjects were 124 students with mental retardation and 91 normal students. The internal consistency of the items on the Korean Version of ABI was investigated using Cronbach's α. The coefficient alpha for the subtests ranged from .85 to .93 in MR students, .89~.94 in normal students and were statistically significant(p<.05). Also, test-retest correlation coefficients ranged .88~.91 in MR students, .88~.92 in normal students, and were statistically significant(p<.01). In addition, criterion-reference validity coefficients for teacher's judgement and subtests ranged .70~.78 in MR students, .72~.81 in normal students and were highly correlated. In Social Maturity Scale and subtests,the Pearson product-moment coefficients of correlation ranged .38~.47 in MR students, .38~.45 in normal students and were accepted statistically significant. Also, construct validity coefficients ranged .51~.75 in MR students, .63~.80 in normal students and were statistically significant(p<.05). As a result, this study suggest the scale can be used for identifyingthe abilities of social adaptation of persons with mental retardation and other disabilities.

3,4-Diphenylsydnone에 조건을 변화시켜가면서 니트로화반응을 시켰다. 반응은 4위치의 phenyl에서만 일어났으며, CH_3COOH-HNO_3조건하에서는 para에 그리고 H_2SO_4-HNO_3조건하에서는 ortho와 para에 진행하여 각각 니트로화합물을 얻었다. 생물학적으로 활성을 갖을 것으로 기대되는 아미노기를 갖는 sydnone유도체를 얻기 위하여, 이 니트로화합물을 Fe와 2%초산수용액에 의해 환원시켰다. 이들 생성물의 확인은 IR과 NMR로 검토하였으며 원소분석으로 확정지었다. Nitration of 3,4-diphenylsydnone was examined under various conditions. Reaction took place only at phenyl which was at 4-position of sydnone ring, and it was found that para-substituent was obtained under CH_3COOH-HNO_3 condition, whereas under H_2SO_4-HNO_3 condition ortho-and para-substituent was obtained. In order to obtain amino group containing sydnone derivative which was expected to be biologically active, this nitro compound was reduced by iron and 2% aqueous acetic acid. The products thus obtained were identified by IR and NMR spectroscopy and confirmed by elemental analysis.

안용민,권용실,권준수,민성호,박두병,양문정,소형석,송종호,신윤식,우행원,유범희,이홍석,정한용,한창환,김용식 大韓神經精神醫學會 2002 신경정신의학 Vol.41 No.5

연구목적: 이 다기관 공동임상연구는 사용 중인 항정신병약물을 ’직접 교체 방법’또는 ’시작-감량 교체 방법’중 한 가지 방법으로 올란자핀으로 교체한 후, 안정성 측면에서 두 교체 방법 간의 비교와 교체후의 변화를 관찰하기 위한 것이다. 방법: 국내 13개 병원의 입원 및 외래에 내원한 환자들 중 ICD-10 지단기준으로 정신분열병에 해당되며, 임상적으로 항정신병약물 교체가 필요한 환자를 대상으로 하였다. 두 가지 교체 방법 중 한 가지를 무작위로 피험자에 적용하였으며, ’직접 교체 방법’에 배정된 경우에는 사용중인 항정신병약물을 일시에 중단하고 10㎎의 올란자핀을 바로 투여하였고, ’시작-감량 교체 방법’에 배정된 경우는 10㎎의 올란자핀 투여하고 2주에 걸쳐서 기존 약물을 감량하여 중단하였다. 올란자핀 사용기간은 총 6주이며, 용량은 5∼20㎎ 범위로 제한하였다. 한정성 평가를 위해서 체중, 생명징후, 자발적인 이상반응 복, 실험실 검사 그리고 Simpson-Angus Scale(SAS), Barnes akathisia rating scale(BARS), Abnormal involuntary movement scale(AIMS). Liverpool University neuroleptic side effect rating scale(LUNSERS)등을 이용하였다. 결과: 총 103명의 정신분열병 환자를 대상으로 하였다. 사용한 올란자핀의 용량, 벤조디아제핀의 병용률, 탈락률과 탈락 사유, 자발적인 이상반응 보고, 생명징후, 실험실 검사 그리고 대부분의 부작용 척도 상에서 임상적으로 의미 있는 차이를 두 교체 방법간에 발견하지 못하였다. 다만 AIMS의 감소는 ’직접 교체 방법’군에서 보다 적었고, 항콜린제의 병용률은 ’시작-감량 교체 방법’군에서 보다 많았다. 기저 상태에서 전체 피험자의 SAS와 BARS 점수는 각각 3.5점과 1.8점이었으며 70% 이상의 피험자가 고프로락틴 혈증을 보였다. 올란자핀으로 교체한 후, SAS, BARS, AIMS 점수의 유의한 감소가 있었으며 고프로락틴 혈증을 보인 피험자 분율도 약 30%이하로 감소하였다. 그러나 교체 방법과 상관없이 올란자핀 교체 후 유의한 체중 증가가 있었다. 결론: 이 연구를 통해 교체 방법에 관계없이 비교적 안전하고 용이하게 올란자핀으로 교체 할 수 있음을 알 수 있었다. 그리고 기존 항정신병약물을 올란자핀으로 교체함으로써 일부 부작용들을 줄일 수 있음을 간접적으로 관찰할 수 있었다. 하지만 이 연구는 여러 제한점과 문제점을 지니고 있기 때문에 보다 체계적인 연구를 통해 검정이 필요하리라 생각된다. Objectives: This multicenter clinical trial involving 13 hospital sites compared the safely of switching to olanzapine between ’direct switching method’ and ’start-tapering switching method’. Method: This study included both inpatients and outpatients who fulfilled the criteria for schizophrenia as defined in the ICD-10, and were in need to be appropriate for switching antipsychotics. Subjects were randomly assigned to one of the two switching methods. For ’direct switching method’group, previous antipsychotics were abruptly discontinued and 10㎎ of olanzapine was administered, and previous antipsychotics was gradually tapered for 2 weeks. Olanzapine was used for 6 weeks and the dose was adjusted within the range of 5-20㎎. The safety of switching to olanzapine was measured with vital sings including body weight, adverse events reported spontaneously, laboratory tests, and various scales such as Simpson-Angus Scale(SAS), Barnes Akathisia Rating Scale(BARS). Abnormal Involuntary Movement Scale(AIMS), and Liverpool University Neuroleptic Side Effect Rating Scale(LUNSERS). Results: 103 patients were switched to olanzapine in this study. The comparison between two switching methods did not show any significant difference in the dosage of olanzapine used, the concomitant use of benzodiazepine, the rate and reasons of drop-out, the adverse events, vital signs, laboratory tests, and most scales for measuring side-effects. However, the decrease in AIMS scores was significantly lower in ’direct switching method’ group, and the concomitant use of anticholinergics was comparatively greater in ’start-tapering switching method’ group. At baseline, SAS and BARS scores were 3.5 and 1.8 points respectively, and more than 70% of the subjects showed hyperprolactinemia. After switching to olanzapine, SAS, BARS, and AIMS scores were significantly decreased and the proportion of the patients with hyperprolactinemia was also decreased to less than 30%. However significant weight gain after the treatment of olanzapine was observed regardless of switching method. Conclusion: This study may suggest that switching to olanzapine can be done with relatively high safety regardless of switching methods and olanzapine can significantly decrease some side-effects induced by other antipsychotics.
