任庸淳,李根泳 성균관대학교 1998 학술회의지원논문목록집 Vol.1998 No.-

MPEG-2 TM5의 비트율 제어 방법에서는 현재 매크로 블록의 Q₁, N_act₁및 mquant₁값은 바로 이전 매크로블록으로부터 예측하여 현재 매크로블록의 양자화값으로 사용함으로써, 현재 매크로블록의 급격한 변화가 초래하여 영상의 질을 떨어뜨린다. 제안한 방법은 현재 매크로블록과 인접한 매크로블록들의 Q₁, N_act₁및 mquant₁값 각각에 대하여 평균을 취하여 적용하였다. 그렇게 함으로써 제안한 비트율 제어 방법은 현재 매크로블록이 인접 매크로블록과 비교하여 급격하게 변하지 않게됨에 따라 개선된 PSNR을 나타내었다. In bitrate control of MPEG-2 TM5, Q, N_act₁, and mquant,₁ of present macroblock are predicted from those of previous macroblock. It results in poor image quality because of abrupt change of them. We proposed a method predicting Q₁, N_act₁and mquant, of present macroblock by averaging those parameters of adjacent previous macroblocks. As a results, it shows improved PSNR compared to bitrate control of MPEG-2 TM5.

Ovarian pregnancy is an uncommon form of the ectopic pregnancies. The ovarian vascularity results in maternal hemorrhage early in the first trimester, which disrupts the pregnancy and usually ruptures the ovary with sufficient hemoperitoneum to require emergency operation. This report presents 10 cases of ovarian pregnancy by retrospective review between January 1986 and December 1995 at the Department of Obstetrics and Gynecology, Soonchunhyang University Hospital. There was 19,849 deliveries and 637 ectopic pregnancies during same period. It showed that the incidence of ovarian pregnancy was 3.21 % of all ectopic pregnancies. The clinical features of ovarian pregnancy revealed that abdominal pain was the major symptom, and history of amenorrhea was obscure. Because of life-threatening course, the early diagnosis and treatment of ovarian pregnancy is important. The clinical diagnosis of ovarian pregnancy was more difficult than that of tubal pregnancy.

This paper focused on the application at actual teaching field in the way of performance assessment that lately entered the stage as an alternative plan traditional way of evaluation at the 5th grade social studies economic area in elementary school. This paper presented the ground of an argument of performance assessment introduction based on a developmental evaluation view, cognitive psychology and multi-intelligence theory. Constantly to be feed back the goal of social studies economic education, guidance content, evaluation, we established the goal of social studies economic education and analyzed the content of economic education by ten pieces of basic concept in the 5th grade social studies elementary school. On the basic of these, we reconstructed by 8 pieces of basic concept against being guide at the 5th social studies curriculum now in use. One hand for the development of performance assessment of economic area, this paper utilized the existing techniques of performance assessment and made a criterion plan of the performance assessment . on the basic of this. We projected the way of performance assessment by basic concept. The result is as follows First, The production of a criterion plan of performance assessment can be a suitable tool of performance assessment. Second, if we used compound numbers technique of performance assessment, the result of evaluation would bring along the synergy effect. Third, we extracted the economic basic concept against being guided to the 5th grade in the elementary school. For further more studies, this paper suggests that the test way of performance assessment must be exploited as possible as early to know how much contribute to make progress higher order thinking like originality and problem solving capacity to information-oriented society and knowledge foundation society in the coming up.

We have analyzed this influence base on survey of central government administration officers and local officers which were taken on 2001 and 2003. Also, we anticipates that this result would help actual field adjustment as well as preparation of speciality of officers. The results are summarized as follows : First, a survey in 2001 shows 68.8 percent of local administration officers answered that their expertise about environmental services were above average. Then, the result was increased to 82 percent of officers responsed that they have more than average expertise and experience in 2003 survey. Secondly, government have to increase effectiveness on regulation or restriction duty. Nonetheless, the survey shows that significant decrease of effectiveness from 2001 to 2003 in both central and local goveniment officers. It means that they spent more effort on local community environmental regulation program other than restriction duty to requisited from central government. Third, moreover, local government do not want to faculty of environmental administration and insists that governments need to set the regulation for particularity of regions.

연구목적 : 본 연구는 치매와 우울증을 다차원적으로 평가할 수 있는 도구인 Psychogeriatric Assessment Scale(PAS)의 한국판(PAS-K)을 개발하기 위한 것이다. 방 법 : 번역, 역번역, 그리고 세차례의 예비조사를 통하여 PAS-K를 제작하였다. 60세 이상의 노인 291명(임상환자군 : 58명, 지역사회노인군 : 168명, 수용시설 거주자 : 67명)과 그들의 정보제공자들을 대상으로 PAS-K, Geriatric Depression Scale(GDS), Korean version of Mini-Mental State Examination(MMSE-K), Hamilton Rating Scale for Depression(HRSD), 그리고 Hachinski Ischemic Score 를 적용하고, Diagnostic Interview chedule(DIS-Ⅲ-R)을 사용하여 치매와 우울증을 진단하였다. PAS-K의 신뢰도와 타당도를 평가하고, 예민도와 특이도, Kappa값, 그리고 ROC커브 분석법을 이용하여 PAS-K의 6개의 소척도들(피검자면접 : 인지기능 장애척도, 우울척도, 뇌졸중척도, 정보제공자면접 : 인지기능 저하척도, 행동변화척도, 뇌졸중척도)의 최적 절단점을 구하였다. 결 과 : PAS-K는 높은 내적 일관성을 보였고, 검사자간 신뢰도도 만족할 만한 수준이었다. PAS-K의 소척도들을 다른 표준화된 검사도구들과 비교하였을 때 인지기능 장애척도와 인지기능 저하척도는 MMSE-K와, 우울척도는 GDS 및 HRSD와 유의한 상관관계를 보였으며, 뇌졸중척도는 Hachinski Ischemic Score와 통계적으로 의미있는 상관관계를 보였다. 최적절단점은 인지기능 장애척도 10점, 인지기능 저하척도 3점, 우울척도 5점, 피검자면접과 정보제공자 뇌졸중척도 모두 1점, 그리고 행동변화척도 2점으로 추정하였다. 결 론 : 본 연구를 통해 PAS-K의 신뢰도와 타당도가 검증되었고, 노인정신의학 역학연구나 보건분야에서 치매와 우울증의 임상경과관찰 및 일차 선별도구로서 유용하게 사용될 수 있게 되었다. Objectives : This study was designed to develop the Korean version of the Psychogeriatric Assessment Scale(PAS-K), a multidimensional screening tool for the dementia and depression. Methods : Through three times preliminary trials, the authors translated PAS into Korean. The PAS-K, Geriatric Depression Scale, Hamilton Depression Rating Scale, Hachinski Ischemic Scale and Mini-Mental State Examination-Korean version were administered to 291 subjects over the age of 60 and the same number of their informants(67 subjects were institutionalized, 168 subjects were in community, 58 subjects were psychiatric hospital patients). And the Diagnostic Interview Schedule(DSM-Ⅲ-R) was independently administered to exactly diagnose dementia and depression. The reliability and validity test, optimal cut-off point estimation for six each scale and ROC curve analyses were done to investigate the diagnostic validity of PAS-K. Results : Internal consistency and interrater reliability of the PAS-K were high. Concurrent validity of each scales of PAS-K was good in being measured with other standardized scales. The optimal cut-off points of each scale of the PAS-K were estimated as follows : 1) Stroke Scale of subject interview : 1, 2) Cognitive Impairment Scale of subject interview: 10, 3) Depression Scale of subject interview : 5, 4) Stroke Scale of informant interview : 1, 5) Cognitive Decline Scale of informant interview : 3, and 6) Behavioral Change Scale of informant : 2. conclusions : The PAS-K was valid and reliable screening tools for detecting dementia and depression. Therefore the PAS-K could be widely and extensively used in psychogeriatric epidemiological research or clinical setting of primary screening for dementia and depression.

Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

Encystation of Giardia lamblia by High Bile and Alkaline pH and Its Ultrastructural Changes during Encystation

YONG, TAI-SOON,YANG, HYE-WON,IM, KYUNG-IL,PARK, SOON-JUNG 한국미생물 · 생명공학회 2000 Journal of microbiology and biotechnology Vol.10 No.3

Giardia lamblia, a human pathogen causing outbreaks of diarrhea, recently became a focus of great concerns in the fields of both medical and environmental microbiology. To develop the experimental tools to study giardiasis, encystation, one of the major processes in its life cycle, was reconstituted by inducing an axenic culture of a flagellated form of G. lamblia into a cyst form under high concentration of bile and alkaline pH condition. The successful induction was confirmed by Northern analysis of resulting increased expression of the CWP1 gene encoding the cyst wall protein 1. An examination of the encystation process with SEM (scanning electron microscopy) and TEM (transmission electron microscopy) revealed that the trophozoite, a flagellate with a bilateral symmetry, was transformed to a cyst form with an oval-shape and defined filamentous wall. The encystation was found to cause a disappearance of the flagella and an invagination of the adhesive disc. An extensive formation of rER (rough endoplasmic reticulum) was observed after 24h of induction, indicating an active synthesis and export of proteins during this process. The vital staining of the in vitro-induced cysts showed that most cysts maintained their viability.
