The purpose of this study was to find out the problems of P ­ A cephalometric measurements used in the facial asymmetry analysis and to show the necessity of using three ­ dimensional morphometry. Steel ball (1.2㎜ in diameter) were attached in twenty seven landmarks of symmetrical artificial human skull, and eighty seven different asymmetrical artificial human skulls were formed by enlarging gradually remus height, mandibular body length, and gonial angle of the hemiface. From the P ­ A cephalometry and three ­ dimensional morphometry of each skull types, three linear measurements (representing ramus height, mandibular body length, mandibular length) and two angle measurements (representing gonial angle, menton deviation) and two area measurements (representing mandibular area, lower facial area) were acquired and made into asymmetry index. Menton deviation itself was used as asymmetry index while left ­ right differences were used in the other measurements. These asymmetry index were compared with each other to show the different aspect of the seven asymmetry index according to the degree of actual facial asymmetry. Through the statistical analysis, following results were obtained. 1. When actual ramus height difference becomes large, menton deviation and lower facial area asymmetry index of P ­ A cephalometry were reduced significantly more than those of three ­ dimensional morphometry (p<0.001). 2. When actual mandibular body length difference becomes large, ramus height, lower facial area asymmetry index of P ­ A cephalometry were reduced significantly (p<0.001) while mandibular body length, mandibular length, gonial angle, and mandibular area asymmetry index of P ­ A cephalomentry were magnified significantly more than those of three ­ dimensional morphometry (p<0.01). 3. When actual gonial angle difference becomes large, gonial angle asymmetry index of P ­ A cephalometry was reduced significantly (p<0.001) while lower facial area, mandibular body length, and mandibular area asymmetry index were magnified significantly more than those of three ­ dimensional morphometry (p<0.01). 4. When the correlation between actual ramus height difference and seven asymmetry index of P ­ A cephalometry and three ­ dimensional morphometry was analysed, no difference between P ­ A cephalometry and three ­ dimensional morphometry was found (p<0.01). 5. When the correlation between actual mandibular body length difference and seven asymmetry index of P ­ A cephalometry and three ­ dimensional morphometry was analysed, significance was found in mandibular body length, mandibular length, menton deviation, mandibular area, and lower facial area (p<0.001) while significance was found only in gonial angle of three ­ dimensional morphometry (p<0.01). 6. When the correlation between actual gonial angle difference and seven asymmetry index of P ­ A cephalometry and three ­ dimensional morphometry was analysed, significance was found in gonial angle (p<0.001) while significance was found only in lower facial area of three ­ dimensional morphometry (p<0.01). The above results suggest that three ­ dimensional morphometry show to be necessary for the accurate facial asymmetry analysis.

경상운동은 다른 쪽의 신체에서 일어나는 의도된 움직임의 경상 반전으로 발생하는 한 쪽 신체의 무의식적인 운동이다. 본 연구는 뇌졸중으로 인한 편마비 환자에게서 나타나는 경상운동이 상지기능에 미치는 영향에 대해 알아보고자 하였다. 65명의 뇌졸중 환자를 대상으로 연구한 결과, 경상운동이 나타나지 않은 환자군의 상지기능은 경상운동이 나타난 환자군의 상지기능과 통계학적으로 유의한 차이를 보였으며, 경상운동이 나타난 환자군에 비해 상지기능이 좋은 것으로 나타났다. 또한, 경상운동이 나타나지 않은 환자군과 경상운동이 경한 환자군, 경상운동이 중한 환자군의 상지기능을 비교한 결과 경사운동이 적게 나타날수록 상지기능이 좋은 것으로 나타났다. 연구의 결과를 종합하여 볼 때, 뇌졸중으로 인한 편마비 환자에게서 나타나는 경상운동은 상지기능을 감소시키는 요인 될 수 있는 것으로 나타났다. The purpose of this study was to compare upper extremity's motor function according to the mirror movements in hemiparetic patients with stroke. Mirror movements are involuntary movements in one side of the body that occur as mirror reversals of the intended movement on the other side of the body. The subjects of the study were 65 stroke patients who were admitted from May, 2004 to April, 2005 in the Y University medical center. This study used the Manual Function Test(MFT) and the Purdue pegboard test to evaluate upper extremity‘s motor function. The severity of mirror movements were assessed according to the criteria of Woods and Teuber. The results of the study was as follow; First, The upper extremity‘s motor function in hemiparetic patients without mirror movements was significantly different in hemiparetic patients with mirror movements(p< .05). Second, The upper extremity's motor function in hemiparetic patients with mild mirror movements was significantly different in hemiparetic patients with severe mirror movements(p< .05). The result showed that the mirror movements in hemiparetic stroke patients are correlated with upper extremity's motor function and the severity of mirror movements affected upper extremity's motor function. 경상운동은 다른 쪽의 신체에서 일어나는 의도된 움직임의 경상 반전으로 발생하는 한 쪽 신체의 무의식적인 운동이다. 본 연구는 뇌졸중으로 인한 편마비 환자에게서 나타나는 경상운동이 상지기능에 미치는 영향에 대해 알아보고자 하였다. 65명의 뇌졸중 환자를 대상으로 연구한 결과, 경상운동이 나타나지 않은 환자군의 상지기능은 경상운동이 나타난 환자군의 상지기능과 통계학적으로 유의한 차이를 보였으며, 경상운동이 나타난 환자군에 비해 상지기능이 좋은 것으로 나타났다. 또한, 경상운동이 나타나지 않은 환자군과 경상운동이 경한 환자군, 경상운동이 중한 환자군의 상지기능을 비교한 결과 경사운동이 적게 나타날수록 상지기능이 좋은 것으로 나타났다. 연구의 결과를 종합하여 볼 때, 뇌졸중으로 인한 편마비 환자에게서 나타나는 경상운동은 상지기능을 감소시키는 요인 될 수 있는 것으로 나타났다.

New technology plays a role of stimulator in releasing the constraints on growth imposed by resource endowment in any society. In an economy with high population pressures and limited land, increases in output depend on the development of land-saving technology, that can release the constraints imposed by the inelastic supply of land. The development of fertilizer-responsive crop varieties, which is identified as biological technology, can essentially be a new technology designed to facilitate the substitution of fertilizer (or pesticides) for scare land and to raise yield per Ha. In an economy characterized by a relative scarcity of labour, the improvement of agricultural machinery that can save labour and raise labour productivity may reduce the problem of labour shortage. The constraints imposed by an inelastic supply of labour may be offset by advances in so called mechanical technology. The Technology of Direct-Seeding in paddy rice cultivation (TDS), which has rapidly diffused among individual farmers in recent years, may be the same scale-neutral technology as Tong-il HYVs. It may be said that the TDS has been designed to solve the problem that results from the bottlenecks of labour shortage and high labour cost. It is also assumed that the TDS may be the technical innovation that is induced by changes in factor endowments in market economy while Tong-il HYVs may be the technological development that is leaded by the government's incentives to attain self-sufficiency of staple food. In the area of agricultural policy, the study has a crucial role in establishing a desirable direction for agricultural reconstruction-policy for improving agricultural infrastructure and in providing information for the scientific technology-policy for attaining more efficient resource allocation in agricultural research.

Objectives : In the present study, we investigate the association between homozygosity of the 4-repeat allele (4/4) at the DRD4 and the response to the treatment with MPH in Korean children with ADHD. Methods : The present study included 71 children with ADHD (8.231.78 years) from two children's psychiatric clinics in South Korea. All drug-naive children with ADHD were treated with MPH for about 8 weeks. The subjects who showed improvement of over 50% compared with the baseline ARS score after 8 weeks of treatment were termed as the 'good response' group. The subjects who showed an improvement of less than 50% were considered as the 'poor response' group. After genotyping for DRD4 were performed, we investigated correlation between homozygosity for 4-repeat allele at DRD4 and the response to MPH treatment. Results : We found that while 79.5% (31/39) of the subjects with homozygosity of 4-repeat allele at DRD4 showed good response to MPH treatment, 68.8% (22/32) of the subjects without homozygosity of 4-repeat allele at DRD4 showed poor response to MPH treatment according to ARS scores assessed by their parents (χ²= 16.762, df= 1, p<0.01). We also found that while 61.5% (24/39) of the subjects with homozygosity of 4-repeat allele at DRD4 showed good response to MPH treatment, 87.5% (28/32) of the subjects without homozygosity of the 4-repeat allele at DRD4 showed poor response to MPH treatment according to ARS scores assessed by their teachers (χ²= 17.698, df= 1, P<0.01). Conclusion : Our findings support an association between the homozygosity of 4-repeat allele and a good response to MPH in ADHD of Koreans.

기근홍,조국형,범진선 朝鮮大學校 附設 醫學硏究所 1992 The Medical Journal of Chosun University Vol.17 No.2

Glial fibrillary acidic protein (GFAP) is one of the intermediate filament proteins, It is avaUable for identification of tumors glial cell origin in central nervous system. The specialized cells of the peripheral nervous system could express GFAP. The materials for our study consisted of 25 neurofibroma and 15 neurilemmoma, that resected for diagnosis or definite treatment at Chosun University Hospital from January, 1989 to December, 1991. All cases were performed of immunohistochemical stain for GFAP, vimentin and S-100 protein by ABC method. Immunoreactivity was evaluated and compared with the reactivity of GFAP, vimentin and S-100 protein. All cases of neurofibroma and neurilemmoma was positively stained in the neoplastic cells to the vimentin and S-100 protein. GFAP were positively stained in 10 of 25 neurofibroma (40%) and 11 of 15 neurilemmoma (73%). In the neurilemmoma, the positive cells were found primarily in cellular area, rarely in verocay bodies. Dermal neurofibromas were negative for GFAP, except of deeply located plexiform neurofibromas. Positive tumor cells were usually bipolar and spindle-shaped. The GFAP positive tumor cells were appeared around in hyalinized vessels in many cases.

급성 복통을 주소로 진단된 자발성 양측 부신 출혈에 의한 부신피질부전

Thomas Addison은 1855년 발표된 그의 논문에 일차성 부신피질부전에 의하여 발생한 근력 약화, 피로, 식욕부진, 복통, 체중감소, 색소침착 등에 대하여 처음으로 기술하였다[1,2]. 부신피질부전은 부신피질의 파괴에 의해 발생하는 당질 코르티코이드 결핍과 관련된 일차성과 뇌하수체에서 혈청 부신피질자극 호르몬(adrenocorticotropic hormone, ACTH)의 분비장애에 의해 발생하는 이차성으로 구분할 수 있다. 일차성과 이차성의 중요한 차이는 무기질 코르티코이드의 결핍이 일차성에는 있고 이차성에 는 없다는 점이다. 일차성 부신피질부전의 원인으로 이전에는 결핵에 의한 양측 부신 파괴가 가장 흔한 원인이었으나, 결핵 진단율 및 치료약제 보급률이 좋아진 20세기 후반부터는 감소 추세를 보이고 있으며, 선진국에서는 자가면역성 부신염에 의한 일차성 부신피질 부전이 80~90%로 가장 흔한 것으로 보고되었다[3]. 이외에 다른 감염성 질환, 전이성 암, 림프종, 부신출혈 또는 경색, 약물 등의 원인을 들 수 있다. 일차성 부신피질부전의 임상 증상과 징후로는 전신무력감, 식욕부진, 피로감, 체중감소, 과다한 색소침착, 오심, 복통, 기립성 저혈압, 저혈당, 전해질 장애 등이 올 수 있고, 심하면 탈수, 저혈압, 의식장애 및 쇼크가 동반될 수 있다. 일차성 부신피질부전은 본 증례와 같이 드물게 양측 부신 출혈성 경색으로 인해 발생되는 경우가 보고되었는데, 위험인자로는 항응고제 또는 헤파린 투여, 혈전성 질환, 항인지질 증후군과 같은 과응고 상태, 물리적 외상, 감염, 심한 스트레스와 관련되어 발생할 수 있으며 드물게 임신, 부신 종양, 쇼크 등이 원인이 되고 있다[4,5]. 그러나 본 증례와 같이 원인 없이 발생한 자발성 출혈에 의한 부신피질부전의 보고는 매우 드물다. 양측 부신 출혈의 임상 증상과 징후로는 저혈압, 쇼크, 복부, 등, 옆구리, 흉부의 통증, 발열, 의식저하, 복부 강직, 반발 압통 등이 있다[6]. 적절한 치료를 시행하지 않으면 쇼크가 진행하여 혼수와 사망에 이를 수 있어 정확하고 빠른 진단과 치료가 필요하다. 환자가 생존한다면 부신 기능은 드물게 수개월 후 정상으로 회복될 수 있다[7]. 저자들은 상복부 통증을 주소로 내원한 환자에서 매우 드물게 원인 없이 발생한 자발성 양측 부신 출혈에 의한 급성 부신피질부전 1예를 경험하였기에 보고하는 바이다.
