Nineteen non-insulin dependent diabetic (NIDD) and 19 healthy control women participated in this study of the relationship between glycemic control and the level of zinc and copper in the serum and urine. Urinary zinc level in the NIDD women was significantly higher(P<0.01) than that of the controls. There was no difference in serum zinc level between the two groups. All of the serum and urinary copper levels were significantly higher(P<0.05) in the NIDD women compare to control women. In the NIDD women, urinary protein was related to serum zinc(r=0.515, P<0.05) and to 24-hr urine zinc(r=0.623, P<0.01). However, serum albumin was related to urinary zinc(r=0.570, P<0.01) in the NIDD women. In the NIDD women, glucose control by measuring fasting blood sugar, urinary glucose and urinary protein was correlated with the urinary copper level(r=0.455, P<0.05 and r=0.515, P<0.05, r=0.511, P<0.05, respectively). Nutrients intake were unrelated to glycemic index but, dietary fiber intake was negatively correlated with age (r=-0.593, P<0.01) in the NIDD women.

The growth patern and the seasonal changes in nutrient contents of Humulus japonicus wereinvestigated. Stem length of H. japonicus reached the maximum from 240 to 260 Julian date and the median value was found at 255 Julian date. The maximum leaf area was observed from 235 to 248 Julian date and the median value was at 240 Julian date. The maximum growth rate of the stem length ranged from 205 to date in the growth rate of the stem length and leaf area was 212 and 205 Julian date, respectively. The growth rate of H. japonicus was related to rainy season and precipitation. Phosphorus and sodium contents of H. japonicus were correlated with maximum potential rate of relative growth. Although stem biomas of H. japo-nicus was 1.5∼3.5 times larger than that of leaf, N content of the leaf (4.48∼5.27%) was about 2 times higher than that of the stem (2.0∼ H. japonicus in sumer. This result provides valuable information for apropriate timing for the removal of H. japonicus.

회화 방법에 따른 뇨중의 칼슘, 마그네슘 및 아연의 함량 비교연구

주은정 又石大學校 1992 論文集 Vol.14 No.-

뇨중 무기질 함량의 분석방법중에서 가장 정확하고 바람직한 회화방법을 모색하고자 뇨와 원심분리한 뇨를 사용하여 low temperature ashing, no ashing 및 습식회화 방법으로 칼슘, 마그네슘 및 아연의 함량을 측정하였다. 1. 뇨와 원심분리한 뇨의 Ca, Mg 및 Zn함량에는 유의적인 차이는 없었다. 2. 뇨중 칼슘과 아연함량은 LTA와 no ashing dilution방법으로 측정한 수치가 습식회화 Ⅰ에 비하여 유의적으로 높으며(P<0.001), standard를 0.1N HNO_3에 희석한 습식회화 Ⅱ와는 유사하게 나타났다. 3. 뇨중 마그네슘 함량은 LTA, no ashing 및 습식회화 Ⅰ사이에 유의적인 차이는 없었으며, no ashing dilution방법이 습식회화 Ⅱ에 비하여 유의적으로 낮았다(P<0.0254). 4. 실험방법 중에서 no ashing dilution방법이 LTA와 습식회화 Ⅱ에 비하여 CV가 낮았다. 따라서 뇨중 무기질 함량의 분석은 회화하지 않고, 묽은 산에 희석하여 측정하는 것이 바람직한 방법으로 나타났으며, 앞으로 영양학 실험에서 많이 이용되고 있는 식이 및 대변의 분석에서도 회화방법에 따른 연구가 필요하다고 생각된다. This study was performed to investigate the influence of ashing techniques on the analysis of calcium, magnesium and zinc in urine. The results obtained were as follows; 1. There were no different in calcium, magnesium and zinc contents of whole urine and centrifuged urine. 2. Urinary calcium and zinc contents were significantly higher (P<0.001) LTA and no ashing dilution than wet ashing Ⅰ. 3. There were no significantly different in magnesium contents of LTA, no ashing dilution and wet ashing I methods. 4. Coefficient of variation was lower no ashing dilution than LTA and wet ashing Ⅱ.

In the present study, the authors hoped to determine whether the children with Attention Deficit Hyperactivity Disorder differed from normals in Auditory Event Related Potential study. The study was performed by selective attentional tasks. Study subjects were grouped into attention deficit hyperactivity disorder group(N=9) and normal control group(N=8) according to clinical information, DSM-III-R diagnostic criteria, several psychological tests. During the selective attentional tasks, subject were submitted to odd-ball test with auditory stimuli of the two different frequencies, under the two conditions of attention or ignorance. Test was performed twice, the first under the condition that should be attend to auditory stimuli and count the target sound, the second condition with reading. The results are as follows : 1) Considering the average value of auditory event related potential wave components over all conditions, the amplitude of wave components at each electrode site was different. Amplitude of N2 wave was larger at anterior portion of the brain and the amplitude of P3b was larger at posterior portion of the brain. 2) At Pz electrode site, amplitude of N2 wave to target and non-target sound was different between boys with attention deficit hyperactivity disorder and normal controls. Amplitude of N2 wave in attention deficit hyperactivity disorder was smaller than normal controls. 3) At Fz, Cz, Pz electrode site, amplitude of P3b wave elicited by target sound was larger than by non-target sound. This discrepancy was not interrelated with subjects group factor or attentiation factor. 4) Amplitude of N2 wave at Fz, Cz electrode site was different according to attend condition. Amplitude of N2 wave under the condition attended to auditory stimuli was larger than under the ignore condition. This discrepancy was not interrelated with subject group factor or stimulus factor. 5) Amplitude of P3b wave at Pz was significantly different according to attention. Amplitude of P3b was greater at attend condition. This discrepancy was not influenced by subject group factor or stimulus type factor. In conclusion, some findings of this study were suggestive there are differences in brain auditory event related potential between the two groups(ADHD vs controls). Further study is necessary to prove and conclude it.

주은정,정성훈,김미재,구영진,배승오,안용민,이규영,김용식 大韓神經精神醫學會 2005 신경정신의학 Vol.44 No.6

Objectives : Previous studies on N0TCH4 gene and schizophrenia have not produced consistent results, and more studies with various ethnicities and populations were warranted. This study was performed with Korean population to find the role of the N0TCH4 gene in the development of schizophrenia. Methods : 235 schizophrenics and 236 normal controls participated in the study. Two SNPs (-1725 A/G and -25 T/C) on the N0TCH4 gene were investigated. Genotyping was done by Taqman assay, and statistical analysis was done by contingency chi-square test for the allele and genotype frequencies and PowerMarker V3.0 for the haplotype. Results : The two SNPs did not deviate from Hardy-Weinberg equilibrium in neither schizophrenics or normal controls. Two groups were not different in terms of allele and genotype distribution for both SNPs. Two SNPs were found to be in linkage disequilibrium. Haplotype analysis could not find an association between schizophrenia and these two SNPs. There was no association between the age at onset and the genotypes for both SNPs. Conclusion : We could not find any significant association between schizophrenia and the N0TCH4 gene in this Korean population. Although there are limitations in this study, this result supports the conclusion that the N0TCH4 gene is less likely to play a major role on the development of schizophrenia in the Asian population.

食餌蛋白質의 種類와 含量이 칼슘代謝에 미치는 影響

朱殷廷 숙명여자대학교 대학원원우회 1988 원우논총 Vol.6 No.-

This article has summarized up-to-dately reported results of experimentation of what effects various sources and levels of dietary protein have on Ca metabolism. 1. When protein intake increases, glomerua Alteration rate becomes remarkably higher but fractional renal tubular reabsorption of Ca decreases. At this time, the balance of Ca shows a negative balance as a result of the increase of urinary Ca excretion. When protein intake increases at the same time with the increase of phosphorus intake, urinary Ca excretion decreases. 2. As for the sources of protein, Ca absorption increases in a high quality protein, and its absorption rate becomes higher when there is an increase of protein intake. Especially, urinary Ca excretion increases more remarkably in animal protein than in vegetable protein. This indicates that sulfur amino acid much contained in the meat helps to increase urinary Ca excretion. 3. Fecal Ca excretion does not change much according to sources and levels of dietary protein. Ca metabolism is affected by the complex interplay of protein, phosphorus, Ca and dietary factors. In addition Ca metabolism can change according to periods of experimentation. Conssquently, it is important to study of effects that we Koreans usually take in dietary protein source and levels on Ca metabolism. And than long-term Ca metabolic studies are to be encouraged and supported in various ways.

저자들은 정신분열병의 일부에서는 태생기 동안 유전 외적인 환경적 요인이 크게 작용할 것이라는 가정 하에 형제 정신분열병 환자군(남 15. 여 7)과 산발성 정신분열병 환자군(남 16, 여 7) 및 정상 대조군(남 16, 여 7)을 대상으로 가족력에 따른 산과적 합병증과 신체 미세 기형을 비교하였다. 산과적 합병증은 Lewis 척도를 이용하여 연구 대상의 어머니와 면담하여 평가하였고 신체미세기형은 Waldrop 척도를 이용하여 측정하였다. 또한 산과적 합병증 및 신체 미세기형과 가족력에에 따라 발병 연령 등의 임상 양상들이 차이를 보이는지 비교함으로써 정신분열병을 좀 더 동질적인 아형으로 나눌 수 있는지를 검토하였다. 1) 형제 환자군, 산발성 환자군 및 정상 대조군의 세균에서 산과적 합병증의 개개의 항목 및 전체 점수의 유의한 차이는 없었다. 신체 미세기형의 경우 입의 미세기 형에서 유의한 차이가 있었으나 그 외에 각 부위별 점수 및 전체 점수에서는 세 군간에 유의한 차이가 없었다. 그러나 대부분의 신체 미세기형 세부 항목 및 전체점수에서 산발성 환자군이 형제 환자군에 비해 높은 신체 미세기형의 점수를 보이는 경향이 있었다. 2) 산과적 합병증의 전체 점수와 신체 미세기형의 전체 점수 사이에 상호 연관성을 찾아볼 수 없었다. 3) 발병연령·정신병리·약물에 대한 반응·병전 기능수준·지연성 운동장애 유무 등의 임상 양상들을 비교하였을때 산발성 환자군과 형제 환자군간에 유의한 차이가 없었다. 4) 산과적 합병증 및 신체 미세기형과 임상 양상들을 비교하였을 때, 형제 환자군에서 분만시간과 회복시 전반적 기능수준간에, 산발성 환자군에서 산과적 합병증의 전체 점수와 발병 연령간에 상관관계가 있었으나 전체적으로 일관된 결과가 도출되지는 못하였다. 위와 같은 결과를 종합하여 볼 때, 산과적 합병증이나 신체 미세기형이 정신분열병의 원인을 밝히는데 유익한 도구가 될 수는 있지만, 가족력 유무에 따라 정신분열병을 보다 동질적인 아형으로 구분하기 힘들다고 생각되었다. In order to test the hypothesis that familial schizophrenics have fewer chances of receiving organic insults during the fetal neural development than sporadic schizophrenics, the authors compared obstetric complications, minor physical anomalies, and other clinical features in sibling schizophrenics, sporadic schizophrenics and controls. Obstetric complications were evaluated by the scale of Lewis, and minor physical anomalies were measured by the Waldrop scale. Sporadic schizophrenics had a significantly higher Waldrop score for mouth than sibling schizophrenics. Although there was some tendency of higher total scores for minor physical anomalies in sporadic schizophrenics, there were no statistically significant differences in obstetric complications and the other minor physical anomalies among three groups. There was no significant correlation between obstetric complications and minor physical anomalies. The clinical features such as age of onset, psychopathology, response to drugs, premorbid functioning, and tardive dyskinesia were not significantly different between sibling and sporadic scizophrenics. In conclusion, while the obstetric complications and minor physical anomalies were suggested to be useful in the search for the cause of schizophrenia, it was difficult to categorize schizophrenics into more homogeneous groups according to family history of schizophrenia using the parameter of obstetric complications and/ or minor physical anomalies.

초등 예비교사의 생물에 대한 특정 공포증 실태 및 생물 교수 효능감과의 관계

주은정 韓國生物敎育學會 2014 생물교육 Vol.42 No.3

In this study, pre-service elementary teacher's specific phobia and its relationship to biology teaching self-efficacy were investigated. For the study, I surveyed 90 pre-service elementary teachers' SUD (subjective Units of Distress level) and biology teaching self-efficacy. Then, several pre-service teachers having specific phobia were interviewed in-depth to explore their concern about specific animal phobias and alternative teaching methods about living things. The result showd that the animals which many pre-service elementary teachers had specific phobias about were; centipedes, snakes, spiders, and insects. Pre-service teachers' SUD had a negative correlation with science and biology teaching self-efficacy. They were concerned about how student would thing them as teacher. Some had been willing to teach living thing units disregarding their fear. Other pre-service teachers said they would teach in using model or media about living things instead of hands-on activity. The others didn't have any alternative teaching method. The pre-service elementary teacher's specific animal phobia can effect negatively on teaching biology with living organism, because their phobia had negative relationship with the biology teaching self-efficacy.
