Memory measures are classified into two kinds of tasks : Explicit memory tests are those whose instructions make explicit reference to an prior learning episode and require conscious recollection of that experience, but implicit memory tests are those where instructions make no explicit reference to an learning episode and require no conscious recollection. Based on task comparison methodology examining interrelationships among different memory measures, a number of striking dissociations and similarities between implicit and explicit memory measures have been found and several theoretical accounts have been advanced to explain these phenomena. This article presents a historical survey and related areas concerning implicit memory, reviews the empirical findings of recent experimental researches, outlines several major theoretical views of implicit memory, and evaluates those theoretical positions.

Pseudomyxoma peritonei is a relatively rare and poorly understood condition in which mucus accumulate within the peritoneal cavity. The presence of cells in the mucin, either inflammatory or neoplastic, distinguishes it from simple acellular mucus ascites caused by mucinous spillage. There are widespread seedings on the peritoneal and omental surfaces with a heavy cancerous glaze. This is principally a complication of borderline or malignant neoplasm of the ovary and/or appendix. We report one female case with pseudomyxoma peritonei from mucinous adenocarcinoma of appendix which was diagnosed incidentally during laparoscopic cholecystectomy.

Resistance syndrome to thyroid hormone (RTH) is a rare autosomal dominant disease that is characterized by decreased tissue responsiveness to thyroid hormone, and it is mainly due to mutations of the thyroid hormone receptor β (THRB) gene. We report here on a 36-years old male who had mild thyroid goiter and general weakness. The thyroid function test showed elevated levels of total T3 and free T4. The levels of TSH and the free α subunit were in normal ranges. Mutation analysis of the THRB gene revealed the missense mutation G345D. We report here on the clinical features and THRB gene mutation analysis of a case of RTH. 본 증례는 다발성 갑상선 결절이 있으면서 갑상선 기능 검사에서 혈청 총 T3, 유리 T4가 증가되었고 갑상선자극호르몬 및 갑상선자극호르몬 유리 알파 아단위의 농도는 정상 소견을 보여 갑상선호르몬 저항성 증후군을 의심할 수 있었고, PCR-direct sequencing에 의한 유전자 검사 결과 THRB 유전자의 exon 9번에서 과오돌연변이(G345D)를 확인함으로써 갑상선호르몬 저항성 증후군을 진단할 수 있었다.

Purpose: Enolase is a cytoplasmic enzyme that catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate in the glycolytic pathway. The aim of this study was to investigate whether the overexpression of neuron-specific enolase (NSE) can serve as a prognostic factor in patients with gastric cancer (GC). Materials and Methods: To assess its prognostic value in GC, NSE expression was measured by immunohistochemistry in a clinically annotated tissue microarray comprising of 327 human GC specimens. Cytoplasmic NSE expression was scored from 0 to 4, reflecting the percentage of NSE-positive cells. Results: In terms of histology as per the World Health Organization criteria (P=0.34), there were no differences between the NSE overexpression (NSE-OE) and NSE underexpression (NSE-UE) groups. The NSE-OE group showed a significantly lower rate of advanced GC (P<0.01), lymph node metastasis (P=0.01), advanced stage group (P<0.01), cancer-related death (P<0.01), and cancer recurrence (P<0.01). Additionally, a Kaplan-Meier survival analysis revealed that the NSE-OE group had longer cumulative survival times than the NSE-UE group (log-rank test, P<0.01). However, there were no significant differences in the serum levels of NSE expression in patients with GC and healthy volunteers (P=0.28). Conclusions: Patients with NSE overexpressing GC tissues showed better prognostic results, implying that NSE could be a candidate biomarker of GC.

국산화는 설계나 제조 단계에서만이 아니라 무기 수명의 전체에 걸쳐 소요된느 비용과 장비의 가용시간의 개념에서 파악되어야 한다. 따라서 현재의 국산화율도 관리 항목으로 설정해야 한다. 그래서 국내 개발 뿐만 아니라 기술도입 생산시에도 수리/정비에 대한 요구 수준을 정의하고 그에 맞는 예산을 수립하지 않으면 안 된다. 국내개발이야말로 비용 대 효과가 가장 큰 국산화 방법이며 이 때는 가격대비 국산화율만이 아니라 기수리종속률 개념의 도입으로 기술자립의 대상을 구체적으로 파악하고 국산화의 방향을 정립할 필요가 있다.
LSTM 학습모델의 성능 향상을 위한 디지털 신호 필터의 비교연구 (학습 모델 예측 성능 향상에 영향을 미치는 비트코인 시계열 데이터 전처리 및 스무딩 기법 적용)

본 연구논문에서는 LSTM 기반의 학습 모델 적용과 그 효용성을 높일 수 있도록 몇 가지 평활 기법을비교, 적용하고자 한다. 적용된 평활 기법은 Savitky-Golay, 지수 평활법, 가중치 이동 평균 등이다. 본연구를 통해 비트코인 데이터에 LSTM모델 적용 시 보여준 결과 값보다 전처리 과정에서 적용된Savitky-Golay 필터가 적용된 LSTM 알고리즘이 예측 성능에 유의미한 좋은 결과를 보였다. 예측 성능결과를 확인하기 위해 비트코인 가격 예측에 따른 복잡 요인을 제거하는데 사용된 LSTM의 경우와Savitzky-Golay LSTM 모델에 따른 학습 손실율과 검증 손실율을 비교하고 그 신뢰성을 높일 수 있도록20회 평균값으로 실험하였다. 그 결과 (3.0556, 0.00005), (1.4659, 0.00002)의 값을 얻을 수 있었다. 결과적으로는 비트코인과 같은 암호화폐가 주식보다 더한 변동성을 가지는 만큼 데이터 전처리 과정에서평활 기법(Savitzky-Golay)을 적용하여 잡음(Noise)을 제거하였으며, 전처리 후의 데이터는 LSTM 신경망 학습을 통해서 비트코인 예측률을 높이는데 가장 유의미한 결과를 얻을 수 있었다.

This study was conducted to determine the main effects of breed, farrowing year, season, parity and generation on gestation length, litter size at birth, and pig weight at birth, 21 days and weaning in swine. The least square means were estimated on the basis of the data obtained from 1,728 litters of Landrace, Large Yorkshire, Hampshire., and Duroc breeds raised at National Animal Breeding Institute from 1975 to 1980. The results are summarized as follows. 1. Large Yorkshire and Duroc were superior in Utter size at birth and Landrace was heavier in the preweaing weight than in the other breeds. 2. The effect of breed for the little size at birth and pig weight at birth, 21 days and weaning was highly significant at 1% level. 3. The effect of farrowing year on the litter size and pig weight at birth was significant at 5% level and there was highly significant difference at 1% level for pig weight at 21 days and weaning. 4. The effect of farrowing season was highly significant at 1% level for pig weight at 21 days and weaning. 5. The effect of parity was highly significant at 1% level for all traits studied except gestation length. The litter size at birth was superior in the groups of the 5th to 6th parity than in the other groups and pig weight at weaning was heavier in the groups of the 2nd to 4th parity than in the other groups. 6. The effect of generation was significant at 5% level for pig weight at birth and was highly significant at 1% level for pig weight at 21 days and weaning.
