成耆昌,崔喜慶,金溶聲 성균관대학교 기초과학연구소 1989 論文集 Vol.40 No.1

Isofemale lines of Drosophila melanogaster were established from Daejon in Korea and were examined in order to investigate the changes of cytotype or strain type by P-M system through 1∼15 generations. The results are as follows: 1. Using π_2 (strong P) strains and bw;st (true M) strains as standard strains, the mean sterility frequencies from Cross A were 20.8%∼34.6% for each generations and the mean sterility frequencies from Cross B were 0.0%∼0.3%. 2. Frequency of strain with P cytotype for each generation was analyzed to be 44.8%(G₁), 59.2%(G₂), 43.7%(G₄), 36.7%(G_7), 29.2%(G_10) and 36.7%(G_15). Therefore it was tend to be low as increased with generation number, but the differencies in percentage of GD sterility between each generation are non-significant statistically. 3. Among the isofemale lines, type conversions were observed. Q→M', M'→Q and M'→M changes have occured with frequency of 18.4%, 8.2% and 4.1%, respectively. The remaining lines (69.3%) were unchanged through several generations. 4. The results suggest that Drosophila melanogaster are appeared temporally as a certain strain type in natural population, but the type conversions were represented by interactions between P elements in each genome and cytoplasm for each generation.

In housing design, the possession of many kinds of electric home appliances EHA and the supply of home automation(HA) are considered as new additional design criteria to develop the shape and area of kitchen and working space. This study attempts to findout the character of the possessins and usage of EHA and the HA. For this purpose, the field survey with the questionnaire and observation has been carried out based on 77 households by housing types (apartment and detached house). Findings are as follows : (1) The households have many kinds of EHA and the possession rate of them is very high. Also, the user preference for larger size of EHA such as refrigerater and washing machine is one of the usage characters of EHA. But, these characters of the possession and usage of EHA have not been considered on the design of kitchen and working area, so the misfits have many problems which are the narrow working space, the lack of storage space, the dead space and the inefficient working circulation in those areas. (2) The households require and recognize the HA as the important home equipment for the home security, the home control and the home management. But the practical usage rate is very low because of the supply system that the HA has been furnished by housing developer not user. So, the user education to give the information and instruction about HA is needed.

결절성경화증 환자에서의 SPECT 뇌영상 : 예비적 연구 A preliminary report

한설희,이상수,정승연 충북대학교 의과대학 충북대학교 의학연구소 1991 忠北醫大學術誌 Vol.1 No.1

간질발작을 포함한 전형적인 삼징후가 동반된 결절성경화증 환자를 대상으로 뇌파검사, 뇌전산화단층촬영술 및 단일광자방출단층촬영술을 시행하였다. 뇌전산화단층촬영술에서는 상의하석회화병소와 조영제증강이 뚜렷하지 않은 피질에 연한 저음영 소견이 관찰되었으며 이어서 시행한 단일광자방출단층촬영술에서는 뇌전산화단층촬영술 소견보다 더 광범위한 부위에 관류결손이 관찰되었다. 단일광자방출단층촬영술은 결절성경화증 환자에서 간질발현 병소인 피질결절을 발견하는데 있어서 전산화단층촬영술 및 뇌파검사보다 더 유용한 방법이며 치료방침 결정이나 예후판정에 있어서도 큰 도움을 줄 것으로 기대된다. Two patients with a well-established diagnosis of tuberous sclerosis and epilepsies as their principal clinical symptom were examined by conventional surface electroencephalography(EEG), computed tomography, and single photon emission computed tomography(SPECT) using the 99mTc hexamethyl prophyleneamine oxime(99mTc-HMPAO). The interictal EEG showed various abnormalities of poor localizing value. Brain computed tomography surely demonstrated subependymal calcifications, although the cortical lesions were not so conspicuous. However, the SPECT images of each patient clearly demonstrated decreased cerebral perfusion in cortical areas. It may be assumed that such perfusion defect areas represent the epileptic cortical tubers or those of altered myelination, which are characteristics of the disease.

The importance of home-environment evaluation has been increased in terms of user comfort and needs. The design principles of architectural color for home environments are needed for the planning of exterior color of apartments. This study attempts to find out the evaluation criteria and their characteristics for the exterior color of apartments. For this purpose, the field survey has been carried out to investigate the exterior color and usage patterns and user's satisfaction for exterior color of apartments based on 369 households living in 12 apartment compounds built in Pusan according to environmental settings (mountain area, seaside area, and mass building area). The evaluation criteria for exterior color of apartments such as the fitness of the home, the harmony with settings and the aesthetic were developed and analyzed based on the ratings of 369 subjects. Therefore, this study as an empirical assessment of the evaluation criteria developed for home environmental color as appropriate concepts for exterior color of home environment can contribute to color planning for apartment exteriors.

박승희,남상길,성낙도 충남대학교 농업과학연구소 1995 농업과학연구 Vol.22 No.2

A Series of meta and para-substituted phenyl N-methylcarbamate derivatives were synthesized and influence of substituents(X) on the molecular orbital(MO) quantities of carbonyl group, carbamylation reaction center, and insecticidal activities(pI_50) were discussed quantitatively. From these findings, the most stable streo conformer(Z) shows that the planer phenyl group occupies vertical(θ=90˚) position on the plane of the N-methylcarbamyl group. The carbamylation mechanism was proposed that the carbamylation process of acetylcholinesterase(ACh.E) by m-methyl substituted phenyl N-methylcarbamate derivatives proceeds via hyperconjugation of m-methyl group and carbonyl oxygene protonation, theromodynamically control reaction with acidic site of ACh.E.

본 연구는 한국 재래산양의 β-lactoglobulin(β- LG) 유전자 발현조절부위의 특성을 구명하기 위하여 PCR기법으로 specific primer를 이용하여 β-LG 발현조절부위를 증폭한 후 염기서열을 분석하여 Sheep종의 β-LG유전자 발현조절부위의 염기서열상의 차이를 분석하였다. 한국 재래산양의 genomic DNA로부터 PCR기법을 이용하여 β-LG 유전자 발현조절 부위를 증폭한 결과 Sheep종에서 보고된 바와 같이 1,077bp의 단편크기로 증폭되었음을 확인 할 수 있었다, Sheep종에서 보고된 β-LG 발현조절 부위의 염기서열과 한국재래산양에서 분석된 염기서열간의 차이는 총 897개의 염기중 46개의 nucleotide에서 차이를 나타내어 94.9%의 상동성을 보였다. 특히 한국재래산양과 Sheep종간 염기서열상의 차이는 Sheep종의 T염기가 재래산양의 C염기로 치환되었거나 반대로 Sheep종의 C염기가 재래산양에서 T염기로 치환되어 있음을 확인할 수 있었다. 이상의 결과에서 β-LG유전자 발현조절부위의 염기서열은 재래산양과 Sheep 종간에 높은 상동성을 보였으나 이들 종간의 발현조절부위의 염기서열상의 차이에 대한 유전자 발현조절 관계와 전사요소는 앞으로 연구가 더 진행되어야 할 것으로 사료된다. This study was analyzed by PCR technique with specific primer in order to investigate the characteristics of β-lactoglobulin (β-LG) gene 5'flanking region in Korean native goat. This work confirmed amplified product of 1,077 bp fragments obtained from the amplification of β-LG promoter from genomic DNA using PCR in Korean native goat. The nucleotide sequence of β-LG gene 5'flanking region in Korean native goat as compared with that of sheep β-LG were different at 46 base of 897 nucleotides, and showed high homology as about 94.9% each breed. Especially we confirmed that the difference of nucleotide sequences between Korean native goat and sheep were consisted of T→C substitution and C→T substitution reversely. As a consequences, the sequences of β-LG gene 5'flanking region showed a high homology between Korean native goat and sheep. Furthermore we should be studied that relationships between the control of gene expression and nucleotide sequences of transcription factor in Korean native goat.
