이현지,이상한,Lee, Hyun-Ji,Lee, Sang-Han 대한수사과학회 2008 대한수사과학회지 Vol.3 No.1

사망진단서의 상당수가 부적절하게 기록되고 있다. 이의 원인으로는 사망진단서 작성에 관한 교육의 부족과 사망진단서 작성자의 무관심 등에서 비롯된 것으로 보인다. 사망진단서 오류는 우리나라의 사망 환자 통계의 신빙성을 떨어뜨리고, 보건 정책 등에 올바르게 반영되지 못하는 결과를 가져오게 된다. 2005년 1월 1일부터 12월 31일까지 1년간 대구 소재 A병원에서 발급된 사망진단서 298건을 연구 대상으로 사망진단서의 오류를 조사하였다. 주오류중 사망기전만 기입한 경우 26건(8.7%), 경쟁 원인 기입은 28건(9.4%), 부적절한 진단은 34건(11.4%)이었다. 1개 이상의 주오류를 가진 경우는 88건(29.5%)이었다. 부오류는 시간 간격을 기입하지 않은 경우가 296건(99.3%), 직접사인과 선행사인은 기록하고 중간선행사인을 제외하였거나 직접, 중간선행, 선행사인에 같은 진단을 기입한 경우는 58건(19.5%), 한 칸에 2개 이상의 진단을 기입한 이중진단인 경우가 56건(18.8%) 등이었다. 오류가 없는 사망진단서는 88건으로, 전체 진단서 298건 중 29.5%밖에 되지 않았다. 사망진단서 작성의 정확성을 기하기 위하여 올바른 교육 프로그램 마련 및 교육의 강화가 절실히 요구된다. This study was conducted to analyze the current problems in completing death certificates and to identify the correct method for completing death certificates. Total 298 death certificates in A hospital from January to December in 2005 were reviewed. There was only 88 death certificates (29.5%) without an error. The frequency of the major errors were 8.7% in 'mechanism of death listed instead of cause of death', 9.4% in 'competing causes', and 11.4% in 'improper sequencing'. The frequency of minor errors were 99.3% in 'absence of time intervals', 19.5% in 'repetition of same cause', 18.8% in "more than 2 causes listed in same space". Errors were common in the completion of death certificates in the middle sized hospital setting. It is very important to complete death certificate accurately in practice. Education in undergraduate course and persistent training in internship and residency program will be needed.

이현지,김종덕,Lee Hyun-Ji,Kim Jong-Deok 한국통신학회 2006 韓國通信學會論文誌 Vol.31 No.4A

RFID 다중 태그 인식이란 하나의 RFID 리더 영역 내에 있는 다수의 태그를 태그 간의 통신 간섭에 의한 충돌을 피하며 고속으로 인식하는 기술이다. 다중 태그 인식 기술은 RFID 시스템의 성능과 안정성을 결정하는 핵심 기술로 중요성이 높다. 논문은 대표적 다중 태그 인식 기술인 QT(Query Tree) 알고리즘의 충돌 비트 위치를 활용하여 개선된 QT-CBP(Query Tree with Collision-Bit Positioning) 알고리즘을 제안한다. 시뮬레이션을 통한 검증 결과 QT-CBP는 태그 정보 비트의 중복성이 높고, 태그 수가 많을 때 QT에 비해 뚜렷한 성능 개선이 있었다. RFID Anti-Collision technique is needed to avoid collision problem caused by Radio interference between tags in the same RFID Reader area. It affects the performance and reliability of the RFID System. This paper propose the QT-CBP(Query Tree with Collision-Bit Positioning) Algorithm based on the QT(Query Tree) algorithm. QT-CBP Algorithm use precise collision bit position to improve the performance. We demonstrated the proposed algorithm by simulation. Our algorithm outperformed when each tag bit streams are the more duplicate and the number of tags is increased, compared with QT.

조류 독감바이러스(avian influenza virus, AIV)는 사람에게서 발생하는 인플루엔자 대유행에 중요한 역할을 한다. 특히 최근 AIV H9N2형에 의한 가금류 감염이 빈번히 나타나고 있어 인체 감염이 상당히 우려되는 실정이다. 본 연구에서는 최종적으로 AIV의 HA와 NA 단백질에 특이적으로 반응하는 항혈청을 생산하고자 하였다. 먼저 감염된 닭에서 분리된 AIV H9N2 한국분리주 A/Ck/Kr/MS96/96의 게놈RNA로부터 RT-PCR 방법으로 HA와 NA 단백질 N-말단부위에 해당하는 염기서열을 증폭하였다. 이렇게 증폭된 DNA단편은 E. coli 발현벡터 pGEX4T-1에 삽입한 후, BL21 세포에서 각각의 GST fusion protein (GST-HAln와 GST-NAn) 형태로 발현하였다. GST-HAln와 GST-NAn은 모두 glutathione sepharose column을 사용하여 분리 및 정제하였으며, 정제된 단배질을 항원으로 사용하여 토끼 항혈청을 생산하였다. 생산된 항혈청의 항원특이성은 AIV H9N2 한국분리주 A/Ck/Kr/MS96/96로 감염된 MDCK 세포의 cell extract를 사용하여 immunoblotting을 수행함으로써 확인하였다. 본 실험결과AIV H9N2의 HA와 NA단백질 N-말단부위에 해당하는 재조합GST fusion protein과, 이들 각각의 단백질에 특이적으로 반응하는 항혈청은 앞으로AIV 감염의 진단 뿐만 아니라, AIV에 대한 기초연구에 중요한 재료로 사용될 것으로 기대한다. Avian influenza virus (AIV) is recognized as key to the emergence of pandemic influenza for humans; there are growing concerns that AIV H9N2 may become more efficient to transmit to humans in the near future, since the infection of poultry with AIV H9N2 has been common in recent years. In this study, we aimed to produce antisera recognizing the HA and NA proteins of AIV H9N2. Initially, coding sequences corresponding to the N-terminal regions of the HA and NA proteins of the Korean AIV H9N2 (A/Ck/Kr/MS96/96) isolated from a domestic chicken were amplified from the genomic RNA. Following cloning of the amplified cDNA fragments into pGEX4T-1 vector, two GST-fusion proteins (GST-HAln and GST-NAn) were expressed in E. coli BL21 and purified with glutathione sepharose columns; the recombinant GST-HAln and GST-NAn proteins were both used as immunogens in rabbits. The antigenicity of the rabbit antisera was analyzed by immunoblotting of the cell lysates prepared from AIV H9N2-infected MDCK cells. Overall, the recombinant HAln and NAn proteins fused to the C-terminus of GST and the rabbit antisera raised against the corresponding recombinant proteins would provide a valuable reagent for AIV diagnosis and basic research.

Background: Oral propranolol has recently been introduced as a successful treatment for infantile hemangioma (IH). Though, there are limited reports on this treatment including large number of Korean patients with IH covering a long-term powder and solution formulation period. Objective: We investigated the effectiveness and side effects of two different formulations of oral propranolol treatment in patients with IH at a Korean tertiary university hospital. Methods: From June 2011 to October 2019, 375 patients were treated with powder- or solution-type oral propranolol starting at 1 mg/kg/day and increasing up to 3 mg/kg/day. Drug effectiveness was evaluated on four scales through sequential photographs by two dermatologists. Side effects were recorded on a medical chart. Results: Overall, the mean improvement scale was 2.61±0.73 at 3 months after treatment initiation. The scale was higher for solution-type than for powder-type oral propranolol at the 3-month follow-up (2.71±0.79 vs. 2.54±0.67, p<0.05). The patients’ mean duration of treatment was 8.56±5.85 months, which was shorter for solution-type than for powder-type oral propranolol (6.0 vs. 10.69 months, p<0.05). Among the total number of patients, 22 reported mild side effects, including loose stools and noticeable sleep disturbance, and few serious side effects such as grunting, while two patients required medical intervention. Conclusion: The patients in our study were effectively treated for IH with oral propranolol without significant side effects and had a shorter treatment duration with solution-type oral propranolol than with powder-type oral propranolol.

이현지 ( Hyun-ji Lee ) 한국미용학회 2017 한국미용학회지 Vol.23 No.4

The purpose of this study was to analyze whether color identity of domestic low-price cosmetic brands have an effect on brand awareness, brand attitude and purchase intention. The data were collected via a self?administered questionnaire from 432 female living in seoul and the capital region. Using SPSS 20.0 and AMOS 20.0 package, Cronbach`s α, a confirmatory factor analysis and a structural equation modeling analysis were performed. The results were as follows. First, color identity factors of the domestic lowprice cosmetic brands were differention, symbolism, association and attention. Second, differenition, symbolism and association of color identity factors had an effect on Brand Awareness. but attention of color identity factors didn`t have an effect on Brand Awareness. Therefore, to increase the attention of color identity, it is necessary to develop a unique color identity strategy that is different from other brands by tone and color variation. Third, the brand awareness didn`t have an effect on the brand attitude. Forth, the brand awareness had an effect on purchase intention. Therefore, it is necessary to develop strategies to strengthen the brand identity of consumers by promotion unified color identity strategy such as brand logo, product container and package, store interior and homepage. Finally, the brand attitude had an effect on purchase intention. But, in this study, the color identity didn`t have an effect on the brand attitude. Therefore, it is necessary to find out the factor of color identity has a positive influence on the brand attitude.

이현지(Hyun-Ji Lee),김창업(Chang-Eob Kim) 한국조명·전기설비학회 2020 조명·전기설비학회논문지 Vol.34 No.5

In this paper, we analyzed the characteristics of 200W hollow shafted BLDC motor using a FEM(Finite Element Method) based software, and compared it with a BLDC motor with an existing shaft. For the hollow shafted motor, the flow efficiency increase, but the motor output, efficiency, and other characteristics are decreased due to the loss increase by magnetic saturation compared with the conventional shafted motor. In this paper, we analyzed the characteristics of the conventional 200W BLDC motor and designed the hollow size of the hollow shafted BLDC motor, which had almost same characteristics as the conventional BLDC motor. Then we had CFD(Computational Fluid Dynamics) analysis for the fluid efficiency of two kind of BLDC motors. The results showed the fluid flow rate of the hollow shafted BLDC motor was about improved 11[%] compared with the conventional shafted BLDC motor. The verification of the design and the characteristics of the hollow shafted BLDC motor was certified by the experiments.

초등사회과 공동체 교육의 해법으로서 인仁

이현지(Lee, Hyun-Ji) 동양사회사상학회 2018 사회사상과 문화 Vol.21 No.2

인공지능 시대의 도래로 급격하게 변화하는 사회구조 아래에서 이 시대가 요구하는 인재상은 공동체의 일원으로서 협력하고 공감하는 능력을 가진 사람이다. 따라서 인공지능 시대를 맞이하는 이 시대 교육의 화두는 공동체 교육이라고 해도 무방하다. 이러한 사회변화에 어떻게 적응하고, 변화에 따라 대두되는 공동체의 삶을 위해서 어떤 가치를 추구해야 할 것인지에 대한 성찰이 요구되고 있다. 이와 같이 사회구조적으로는 공동체적 삶을 위한 지혜와 가치 부여에 대한 요구가 높은 반면, 현대를 살아가는 사회구성원들은 공동체의 일원으로서 삶의 의미를 발견하지 못하고 있으며 공동체의 일원으로서 책무에 대한 인식도낮다. 이러한 문제의 해법을 유가사상의 인仁이 내포하고 있는 진정한 사랑으로서의 지혜에서 모색해 보고자 한다. 이 논문의 목적은 초등사회과 공동체 교육의 해법으로서 인仁의 의미를 살펴보는 것이다. 이 목적을 달성하기 위해서 먼저, 초등사회과 공동체 교육의 실태를 분석할 것이다. 그 다음에는 인仁이 공동체 교육의 사랑이론으로서 가지고 있는 특징을 살펴보고자 한다. 마지막으로 공동체 교육의 해법으로서 인仁의 의미를 고찰할 것이다. Under the rapidly changing social structure with the advent of the artificial intelligence era, the talent awards required by this era are those who have the ability to cooperate and sympathize as members of the community. Therefore, it is safe to say that community education is the hot topic of education in this era, which is the era of artificial intelligence. A reflection is required on how to adapt to these social changes and what values to pursue in the life of the community as they arise. As such, members of society living in modern times can not find the meaning of life as members of the community, while the need for wisdom and values for the collective life is high. The solution to this problem will be sought from the wisdom of Confucian Ren(仁). The purpose of this paper is to examine Confucian Ren(仁) as a solution to community education of elementary social studies. To achieve this goal, we will analyze the status of community education in elementary social studies first. Next, we will look at the characteristics of Confucian Ren(仁) as the theory of love in community education. Lastly, we will consider the meaning of Confucian Ren(仁) as a solution to community education.

연구목적: 신생아실에 있는 무증상 만삭아를 대상으로 대변 내 로타바이러스 항원검사를 시행하여 병원 내로타바이러스 감염을 평가하고 전파경로를 알아보고자 하였다. 방법: 2001년 11월부터 12월까지 이대 목동병원 신생아실에서 만삭아 88명을 대상으로 대변 내 로타바이러스 항원검사를 시행하여 로타바이러스 양성군과 음성군으로 나누어 임상적 특징을 비교하였으며 퇴원 2주 내에 외래와 전화로 추적관찰을 시행하였다. 결과: 총 88명 중 17명(19%)이 로타바이러스 양성이었다. 두 군간 성별, 분만방법, 재태기간, 출생체중, 출생지에서 통계학적 유의한 차이는 없었다. 로타바이러스 양성군에서 혼합수유를 한 경우가 많았다(94% vs 63%. p=0.01). 외래추적관찰 중 로타바이러스 음성군에서 3명이 장염으로 재입원 하였으나 재입원율과 임상 증상에서 두 군간 통계적 차이는 없었다. 결론: 신생아실에서 만삭신생아의 대변 내 로타바이러스 양성률(19%)은 다소 높았으나 대부분 무증상이었다. 따라서 무증상 정상 신생아에서 로타바이러스 선별검사는 불필요할 것으로 보인다. 또한 대변-경구경로의 바이러스 전파를 막기 위해 환아의 격리와 개별적 처리가 필요할 것으로 보인다. Objective : The purpose of this study is to investigate the transmission route and determine the clinical characteristics of rotavirus infection in asymptomatic neonate in the nursery. Methods : From November to December 2001, 88 term neonates in the nursery of Ewha Womans University Hospital were evaluated for the screening of rotavirus infection. Fecal specimens of neonate were tested for rotavirus by latex agglutination. The clinical characteristics were compared between the rotavirus positive and negative group and follow up was done by OPD visiting or by telephone Results : Among the 88 neonates, 17 cases (19%) were rotavirus positive result. There were no difference in sex, delivery method, gestational age, birth weight, birth place between the rotavirus positive group and negative group, but mixed feeding was more common in the rotavirus positive group (p=0.01). Only 3 neonates in the rotavirus negative group were readmitted because of diarrhea. Readmission rate and clinical symptoms were not different in the two groups during follow up. Conclusion : The positive rate of rotavirus in nursery is high, but most of all were asymptomatic. Routine rotavirus screening test among asymptomatic neonate seems to be unnecessary. The neonate with rotavirus have to be isolated for preventing the spreading.
