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.

Korean Oriental Medicine has experienced the fluctuation of its status since modernization started. At the beginning of the modernization, Korean Oriental Medicine faced the crisis of disappearance and, nowadays, its status has risen to the very important position in the medical system of Korea. Korean Oriental Medical doctors have obtained the position of medical profession and enjoyed the exclusive privileges. The study on the status of Korean Oriental Medicine is an interesting subject field in the sense that the empirical research on the social factors concerning the status fluctuation of medical profession in non-western world can be done. Few studies on the social status of Korean Oriental Medicine have been found so far in spite of its ample implication of the subject. This paper conducted the questionnaire survey in order to investigate the views of Korean Oriental Medical doctors about the status of Korean Oriental medicine, factors for the improvement of its status, and the cultivating methods of Korean Oriental Medicine. Depending on the demographic features of Korean Oriental Medical doctors, first, the attitude toward the status of Korean Oriental Medicine was analyzed. The criteria to be investigated were the present and future status of Korean Oriental Medicine. Second, the items for the status improvement of Korean Oriental Medicine was analyzed under the criteria of specialization and scientific movement of Korean Oriental Medicine. Third, the stance of Korean Oriental Medical doctors on the cultivating methods of Korean Oriental Medicine was analyzed under the criteria of the level of awareness of and attitude toward Korean Oriental Medicine.

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.

사망진단서 작성에 있어서 부적절성

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.

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.

현대사회 노인 위기의 진상과 극복 방안

이현지(Lee Hyun Ji) 동양사회사상학회 2015 사회사상과 문화 Vol.18 No.4

최근 한국인의 자살통계를 보면, 2013년 인구 10만 명 당 65세 이상 노인 자살자 수는 64.2명이며, 이는 15~24세의 자살자 수가 11.1명,25~44세가 28명, 45~64세가 37명인 것에 비해 월등히 높은 수치이다(통계청, 2015). 또한 노인 인구 중에서도 연령이 높을수록 자살률이 더 높게 나타난다. 자살통계는 현대사회에서 노인이 가장 소외된 집단이 되었음을 분명하게 보여준다. 현대사회에서 노인은 왜 가장 불행한 집단이 되었을까? 노인이 가장 불행한 집단이 된 것에는 다양한 원인이 있겠지만, 이 글에서는 현대문명의 한계와 관련해서 노인문제의 근본 원인을 규명해 보고자 한다. 현대 인간관의 영향으로, 현대문명은 젊은이가 우월함을 갖는 이성, 욕망, 육체 등과 같은 인간의 세속적인 측면들을 인간으로 전제하게 되었다. 그리고 이것은 노인을 열등한 존재로 인식하는 관점을 내포한다. 이에 따라서 현대문명 건설이 진행될수록, 노인 위기 역시 심화될 수밖에 없는 구조를 갖게 되는데, 오늘날 현대문명이 그 한계를 분명히 노정하면서 노인 위기도 그 극점에 달하고 있는 것이다. 이 논문에서는 현대문명에서 드러나는 노인의 위기가 어떠한지를 살펴보고, 이러한 상황을 해소하기 위한 대안을 모색해 보고자 한다. By the recent Korean suicide statistics, the number of suicide is 64.2 of 100,000 people aged 65 and over. This is much higher than 11.1 persons aged from 15 to 24, 28 persons aged from 25 to 44, and 37 persons aged from 45 to 64. And suicide rate of more aged is higher than that of less aged among the aged. The suicide statistics shows that the aged are the most alienated group in modern society. Why the aged became the most alienated group in modern society? There are many reasons why it became the most alienated group. In this paper, we want to discuss of the fundamental reason related to the limitation of modern society. In modern society, we regard the secular aspects of human being like reason, desire, body and so on which the young can be better by the impact of the modern view of human being. And this makes to regard the aged as the worse. Therefore, the crisis of the aged is deepening by the modernization. Nowadays the crisis of the aged reach the limit. In this paper, we will discuss the crisis of the aged at this time, and explore the way to solve the crisis.

율곡사상과 초등사회과 공동체교육

이현지 ( Lee¸ Hyun-ji ) 동양사회사상학회 2021 사회사상과 문화 Vol.24 No.1

현대사회가 발달하면서 사회구성원들은 개인적인 삶의 영역을 확보하고 자유롭게 영위하는 방식에 더 깊은 관심을 가지는 경향이 나타나고 있다. 이러한 경향이 거대한 트렌드로 나타나고 있는 반면에 여전히 공동체를 형성하고 함께 공존하는 능력을 갖춘 사회구성원에 대한 요구는 커지고 있다. ‘개인’ 대 ‘공동체’의 관계는 어느 사회에서나 어느 쪽에 더 많은 의미를 부여해야 할 것인지에 대한 논란의 중심에 있다. 최근 코로나19 팬데믹의 위기상황에서 부딪치는 문제 가운데 하나는 개인의 자유에 대한 보장과 공동체 안녕을 위한 사회적 통제의 문제이다. 강제적인 통제로 인해서 발생할 수 있는 다양한 사회문제를 간과할 수 없으며, 공동체 구성원의 자발적이고 자율적인 통제가 중요한 변수로 부각되고 있다. 높은 시민의식을 바탕으로 하는 공동체 정신은 엄격하고 강제적인 사회적 통제를 작동하지 않더라도 자발적이고 자율적인 통제력을 발휘하여 사회적 위기로부터 자신과 공동체를 보호할 수 있다. 이러한 문제의식을 바탕으로 율곡사상이 오늘날 현대사회가 직면하고 있는 공동체의 문제에 대해 어떤 지혜를 제공하고 있는지를 탐색해 보고자 한다. 율곡사상은 폭넓은 철학적 쟁점을 포함하고 있을 뿐만 아니라, 사회과교육의 관점에서 볼 때에도 그 의미가 풍부한 사회이론이다. 여기서는 율곡사상의 현대 사회과교육에서 활용가능성과 의미를 살펴볼 것이다. 본 논문은 율곡사상이 공동체교육에서 가지는 의미를 발굴하고, 그를 토대로 하여 초등사회과 교육에서 활용방안을 모색해보고자 한다. 이를 위해서, 먼저 현대사회와 공동체교육의 현주소를 분석하고, 다음으로 초등사회과 공동체교육에서 율곡사상을 활용하는 방안을 모색한 후, 마지막으로 율곡사상을 초등사회과 공동체교육에서 활용하는 의미를 밝히고자 한다. With the development of modern society, members of society tend to be more interested in the way in which they secure a personal sphere of life and operate freely. While this trend is emerging as a huge trend, the demand for members of society who still have the ability to form a community and coexist together is growing. The relationship between ‘individual’ and ‘community’ is at the center of controversy over whether more meaning should be attached to either side in any society. One of the problems encountered in the recent crisis of the Corona 19 Pandemics is the issue of ensuring individual freedom and social control for community well-being. Various social problems that may arise from compulsory control cannot be overlooked, and voluntary and autonomous control of community members is being highlighted as an important variable. The spirit of community based on high civic awareness can protect itself and the community from social crisis by exercising voluntary and autonomous control even if strict and compulsory social control is not in operation. Based on this sense of problem, I would like to explore what wisdom Yulgok thought provides about the problems of the community that modern society faces today. Yulgok thought not only contains a wide range of philosophical issues, but is also a rich social theory in terms of social studies education. Here we will look at the usability and meaning of Yulgok thought in social studies education. This paper seeks to discover the meaning of Yulgok thought in community education, and to explore ways to utilize it in elementary social studies education based on it. To this end, we will first analyze the current status of modern society and community education, then explore ways to utilize Yulgok thought in elementary social studies community education, and finally reveal the meaning of utilizing Yulgok thought in elementary social studies community education.

중학생들의 여성 정체성에 관한 연구

이현지 ( Hyun Ji Lee ) 경북대학교 중등교육연구소 2004 중등교육연구 Vol.52 No.1

In modern society, how does the identity of female is defined? How does feminity is described? How does the identity of female affect to her life? In current culture, there is a tendency that the distinction of gender is disappeared. Sometimes this tendency is regarded as an evidence of equality between genders. But I doubt the idea that weakening of the distinction of gender can provide the real identity of gender. This is a case study of the identity of female. The middle school students of Daegu City and Kyungbuk Province are the study object. This study investigates that ``what kind of the identity of female they have``, ``how they culture the identity of female``, and ``what is the difference of the identity of female between boy and girl students``. Middle school students evaluated that good mother is most womanly woman. Mass media affected greatly to the formation of the identity of female. And boy students gave higher score to ``lovely wife`` and ``sexy woman`` than girl students. The difference of scores was statistically significant.(Kyungpook National Univ.)

Nowadays, family Life is changing very rapidly. But the study on the view of family is not much. Especially, the study to high school students is very few. This study focuses on the high school students' view of family. What kind of image on the family they have? How the view of family has been formed? What is the most important factor in the formation of the view of family? This study also researches the gender identity of high school students. Our main concern is how they confine the manly life and the womanly life. How they evaluate the gender role is another research concern. This study also investigates the ideology about marriage. This study will be a basis to form a healthy value of family life. Especially, through the understanding of high school students' view of family, marriage, and divorce, this study will contribute to improvement of the contents of family culture in the high school.
