This paper deals with providing theoretical bases for the development of gift merchandising strategies for the department store. History of the department store shows that gift merchandising can be a powerful response to changing retail environment. Our empirical survey shows that the behavioral characteristics of gift purchasers are explained and predicted with their value system and their perception of the functions of gift giving. Gift merchandising and other management areas in the department store should use these and other relations found in our survey.

계산 에너지 함수 분석을 통한 궤환성을 갖는 단층신경회로망의 성능개선

고경희,강민제 濟州大學校工科大學産業技術硏究所 1997 尖端技術硏究所論文集 Vol.8 No.1

In this paper, a new method to neglect the third term of the computational energy expression in the single-layer neural network with feedback is introduced. The system often converges to local minima instead of to global minima, because the computational energy is not matched exactly with the cost function being optimized. This system always converges to the way decreasing the computational energy function. Therefore, this system often converges to local minima because of discrepancy between the cost function and the computational function. There are two factors causing these two functions different. One of these two factors is an additionary term to help the system being expressed in binary form, another one is this third term of computational energy expression. Regarding this third term energy very small, it is always ignored in designing the system(¹˙²). However, as the system growing, this third term energy is also growing and this grown term makes the computational energy function much different from the cost function. In results of differency between two functions. system converges to local minima more than before. In this paper, a new method to neglect the third term energy is introduced. Therefore, it is shown that the system with this new method has been improved converging to local minima less than without this method this method eventhough in the big system.

XML 문서의 검색 성능 평가

신인혜,선경희,강순철,박경린 濟州大學校 基礎科學硏究所 2003 基礎科學硏究 Vol.16 No.1

대부분의 사용자들은 자료를 저장하고 검색하기 위하여 관계형 데이터베이스를 사용하여 왔는데, 최근에 차세대 웹문서의 표준으로 주목받고 있는 XML은 데이터베이스와 같이 자료를 표현, 저장, 검색할 수 있는 기능을 가지고 있다. 본 논문에서는 임의로 생성한 검색대상 자료를 데이터베이스에 테이블로 저장하여 검색하는 방법과 XML 문서로 저장하여 검색하는 방법의 검색시간이 성능비교를 행하였다. 성능평가 결과, 검색 파일의 레코드 수가 약 1만개 이하인 경우에는 XML 문서를 이용한 검색이 빨랐고, 그 이상인 경우는 데이터베이스를 이용한 검색 시간이 월등히 빨랐다. XML 관련 검색 파일들을 세부적으로 XML 문서를 저장하는 방법(어트리뷰트로 혹은 엘리먼트)과 C#에서 XML 문서를 읽어드리는 방법(XPath을 혹은 DOM)에 따라 성능평가를 하였는데 XML 문서 작성시 어트리뷰트로 구성하고 마이크로소프트 닷넴 프레임워크에서 제공하는 XPath를 이용하여 XML 문서를 검색하는 방법이 가장 효율적이었다. While most of users have used relational databases to store and search data. XML documents also can represent, store, and search these data like database systems. This paper compares the search time of data in the XML documents with those in database systems. The performance comparison shows that the search time using the XML document is faster than that using database when the number of records is less than then thousand. However, the latter is much faster than the former when the number of records is more than ten thousand. The XML documents can be consist of either using Attributes of Elements. Also, the document can be read either using DOM or XPath. The performance comparison shows that the XML document made up of Attributes and being read using XPath in Microsoft Net Framework provides the fastest search time.

급성 구강감염부위에서 Staphylococcus lugunensis 의 특성

Staphylococcus lugdunensis (S. lugdunensis) is a newly identified pathogenic species of coagulase negative staphylococci and an occasional but not rare cause of severe infections, such as infective endocarditis after dental extraction, bacteremia, osteomyelitis, peritonitis, and soft tissue infections. As antibiotic use increased, resistance rapidly developed. Some strains have plasmids related to antibiotic resistance. To characterize S. lugdunensis in acute oral infection, S. lugdunensis was isolated from the patients with acute oral abscess, osteomyelitis, and normal persons. Antibiotic resistance, in vitro cellular toxicity, in vivo virulence, δ-like hemolysin activity, and synergistic hemolysis on sheep blood agar plates were investigated. The dot blot analysis and Southern blot analysis of staphylococcal DNA was performed with δ-hemolysin gene probe of Staphylococcus aureus. (S. aureus) Staphylococcal DNA was cloned, nucleotide sequence was analysed, and homology was compared with other sequence in Gene Bank. S. aureus, S. lugdunensis, Staphylococcus cohnii (S. cohnii), and other coagulase negative staphylococci (CNS) were isolated from the patients with acute oral infection. The isolation ratio of S. lugdunensis in the patients with infection was higher than that of healthy persons, but the isolation ratio of S. aureus in the patients with infection was similar to that of healthy persons. S. lugdunensis from the patients with acute oral infection showed the resistance to penicillin, methicillin, cephalothin, and clindamycin. S. lugdunensis in the patients had cellular toxicity in vitro and virulence in vivo. All strains of S. lugdunensis had δ-like hemolysin activity against rabbit erythrocytes. Four of the six strains of S. lugdunensis gave synergistic hemolysis with S. aureus on sheep blood agar plates. In dot blot analysis, all strains of S. lugdunensis showed the positive reaction with the probe of δ-hemolysin gene in S. aureus, but a 7.3 kb HindⅢ fragment was observed in the DNA of S. lugdunensis that gave synergistic hemolysis in a Southern blot analysis. The molecular size of partially purified δ-hemolysin was about 50 kd. The cloned fragments from the chromosomal DNA of S. lugdunensis showed the partial homology with the insulin receptor-related and dopamine receptor of humans. These results suggest that S. lugdunensis might be an important pathogen in acute oral infection and show some homology with eukaryotes.

Background: Chronic kidney disease (CKD) has a negative impact on growth and development in children and is a risk factor for neurocognitive impairment; however, there is limited research on the cognitive function of children and adolescents with CKD. This study therefore aimed to investigate the mean intelligence and risk factors for low intelligence in children and adolescents with CKD. Methods: Eighty-one patients with CKD under 18 years old were included in the KoreaN cohort study for Outcomes in patients With Pediatric Chronic Kidney Disease (KNOW-Ped CKD). Participants completed either the Wechsler Intelligence Scale for Children (6–16 years), or Wechsler Adult Intelligence Scale (> 16 years). Results: The mean full-scale intelligence quotient (IQ) was 91 ± 19; 24.7% of participants scored a full-scale IQ below 80. Participants with a short stature (height Z scores < −1.88), failure to thrive (weight Z scores < −1.65), more severe CKD stage (≥ IIIb), longer duration of CKD (≥ 5 years), and those who were Medicare or Medicaid beneficiaries, had significantly lower mean full-scale IQs. Conclusion: On linear regression analysis, the association between the full-scale IQ, and longer duration of CKD and growth failure, remained significant after controlling for demographic and clinical variables. It is therefore necessary to investigate cognitive impairment in pediatric patients with CKD who exhibit growth failure or for a longer postmorbid period. It is believed that early interventions, such as kidney transplantation, will have a positive effect on IQ in children with CKD, as the disease negatively affects IQ due to poor glomerular filtration rate over time.

Recurrence and Treatment after Renal Transplantation in Children with FSGS

Kang, Hee Gyung,Ha, Il-Soo,Cheong, Hae Il Hindawi Publishing Corporation 2016 BioMed research international Vol.2016 No.-

<P>Focal segmental glomerulosclerosis (FSGS) is a common cause of end-stage renal disease and a common pathologic diagnosis of idiopathic nephrotic syndrome (NS), especially in steroid-resistant cases. FSGS is known to recur after kidney transplantation, frequently followed by graft loss. However, not all patients with FSGS suffer from recurrence after kidney transplantation, and genetic and secondary FSGS have a negligible risk of recurrence. Furthermore, many cases of recurrence achieve remission with the current management of recurrence (intensive plasmapheresis/immunosuppression, including rituximab), and other promising agents are being evaluated. Therefore, a pathologic diagnosis of FSGS itself should not cause postponement of allograft kidney transplantation. For patients with a high risk of recurrence who presented with classical symptoms of NS, that is, severe edema, proteinuria, and hypoalbuminemia, close monitoring of proteinuria is necessary, followed by immediate, intensive treatment for recurrence.</P>
