초등 실과 바느질 단원의 모듈 수업이 학업 성취도에 미치는 영향
최염숙 韓國實科敎育硏究學會 1999 實科敎育硏究 Vol.5 No.2
For this study to determine the effect of modules instruction of sewing in elementary schools, two fifth-grade classes were selected: one as the experimental group receiving modular sewing lessons, and the other as the control group receiving conventional sewing lessons, for a period of four weeks. The cognitive, functional, and definitive aptitudes of each student from both groups wee assessed right before and after the experiment. The result showed that functional and definitive achievements were higher in the experimental group while cognitive achievement did not indicate any significant difference. In conclusion, a modular sewing lesson, coping with difference in individual learning abilities, was found to be a better educational method in functional and definitive areas, but not in cognitive area.

저자들은 1977년 1월 1일부터 1980년 12월 31일까지 카톨릭의과대학 부속 여의도 성모병원 신경정신과 입원환자중 전기충격요법을 받은 272명을 대상으로 임상적 고찰을 하여 다음과 같은 결과를 얻었다. 1. 총 입원환자 1,709명중 272명(15.9%)이 전기충격요법을 받았으며 정신분열증이 75.7%, 주요정동장애가 15.5%, 기타질환이 8.8%이었다. 2. 진단별로 보면 정신분열증의 30.4%, 주요정동장애의 22.5%, 기타질환의 2.8%가 전기충격요법을 받았다. 3. 전기충격요법의 시행횟수는 1인당 평균 8.3회(정신분열증, 8.9회;주요정동장애, 6.3회;기타질환, 7회)이었다. 4. 치료의 대상이 되었던 증상은 정신분열증의 경우 피해망상(20.3%)이 가장 많았으며 주요정동장애의 경우 정신운동성지체 혹은 초조(23.0%)가 가장 많았다. The authors performed this preliminary study to investigate the effect of ECT. The 272 psychiatric inpatients who received ECT atthe Department of Neuropsychiatry of Catholic Medical College from 1977 to 1980 were evaluated for clinical features. The results were as follows; 1. ECT was performed in 15.9% of a total of 1,709 inpatients who were admitted during the study period. Of them, 75.7% were diagnosed as schizophrenia, 15.5% as major affective disorder and 8.8% as others. 2. ECT was performed in 30.4% of the schizophrenics, 22.5% of those with major affective disorder and 2.8% of others. 3. Mean number of ECT was 8.3 times a patient. 4. The most common target symptom was persecutory delusion in schizophrenia and psychomotor retardation or agitation in major affective disorder.
고 아밀라아제 혈증을 보인 급성 Lithium Carbonate 중독증 1례

Lithium carbonate is a widely used and invaluable drug in the treatment and prevention of manic-depressive illness. However, lithium cardonate may induce multisystemic adverse effects and toxic effects that, when not recognized, may lead to severe, life-threatening complications. The authors experienced a manic patient who showed severe lithium toxic reactions with hyperamylasemia. The patient was 41-year-old woman who had received lithium carbonate treatment for 3 months. The patient's symptoms and signs of toxic reaction had disappeared after hydration, insulin therapy, and hemodialysis.

목적: To evaluate whether ectopic pregnancy rates differ between natural and hormone replacement endometrial preparation in frozen embryo transfer. 방법: Meta-analysis was performed on the 3 selected studies in the statistical framework R using ‘meta’ package (random effects model: DerSimonian-Laird estimator). The outcome considered in this study was the ectopic pregnancy rates. 결과: The ectopic pregnancy rates were not different between natural and hormone replacement endometrial preparation in frozen embryo transfer (odds ratio [OR] 0.91, 95% confidence interval [CI] 0.40-2.06). 결론: The data presented in this meta-analysis do not support a different risk in ectopic pregnancy between natural and hormone replacement endometrial preparation in frozen embryo transfer.
Transgenic potato expressing Aβ reduce Aβ burden in Alzheimer’s disease mouse model

<P><B>Abstract</B></P><P>Beta amyloid (Aβ) is believed one of the major pathogens of Alzheimer’s disease (AD), and the reduction of Aβ is considered a primary therapeutic target. Immunization with Aβ can reduce Aβ burden and pathological features in transgenic AD model mice. Transgenic potato plants were made using genes encoding 5 tandem repeats of Aβ1–42 peptides with an ER retention signal. Amyloid precursor protein transgenic mice (Tg2576) fed with transgenic potato tubers with adjuvant showed a primary immune response and a partial reduction of Aβ burden in the brain. Thus, Aβ tandem repeats can be expressed in transgenic potato plants to form immunologically functional Aβ, and these potatoes has a potential to be used for the prevention and treatment of AD.</P>

The catalytic conversions of methanol, ethanol, dimethyl ether and diethyl ether to aromatic hydrocarbons (especially benzene, toluene and xylene) were achieved over 0.8%Zn/0.6%La/HZSM-5catalyst with a BTX selectivity as high as over 50% at reaction conditions of 710 K, WHSV 0.8 h1. The selectivity of BTX hydrocarbons in methanol aromatization reaction could remain 35% in 40 h. 2010 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.

Reliability-Based Iterative Proportionality-logic Decoding of LDPC Codes with Adaptive Decision
Youming Sun,Haiqiang Chen,Xiangcheng Li,Lingshan Luo,Tuanfa Qin 한국통신학회 2015 Journal of communications and networks Vol.17 No.3
In this paper, we present a reliability-based iterative proportionality-logic decoding algorithm for two classes of structured low-density parity-check (LDPC) codes. The main contributions of this paper include: 1) Syndromemessages instead of extrinsic messages are processed and exchanged between variable nodes and check nodes, which can reduce the decoding complexity; 2) a more flexible decision mechanism is developed in which the decision threshold can be self-adjusted during the iterative process. Such decision mechanism is particularly effective for decoding the majority-logic decodable codes; 3) only part of the variable nodes satisfying the pre-designed criterion are involved for the presented algorithm, which is in the proportionality-logic sense and can further reduce the computational complexity. Simulation results show that, when combined with factor correction techniques and appropriate proportionality parameter, the presented algorithm performs well and can achieve fast decoding convergence rate while maintaining relative low decoding complexity, especially for small quantized levels (3–4 bits). The presented algorithm provides a candidate for those application scenarios where the memory load and the energy consumption are extremely constrained.
