          On the Performance of Multi-User 2PPM-TH-UWB SIMO Systems in Multipath Channels

          백선영,강윤정,김상준 한국정보통신학회 2009 Journal of information and communication convergen Vol.7 No.3

          In this paper, the performance of ultra-wideband (UWB) single input multiple output (SIMO) systems to achieve high data rate communications is studied in dense multipath environments. The effects of spatial and temporal diversities on the performance of multi-user time-hopping UWB systems using binary pulse position modulation (2PPM) are analyzed. The reduced-complexity Rake receivers based on the selective combining (called SRake) and partial combining (called PRake) are considered. The theoretical and simulation results show that the BER performance of the UWB system can be enhanced as the number of array elements and/or Rake fingers increases. Moreover, we observe that SRake is more effective for the IR-UWB systems to achieve a good BER performance, as compared with PRake

        • 영화에서 나타난 동ㆍ서양 의복색의 상징성에 관한 연구

          백선영 한국패션뷰티학회 2005 한국패션뷰티학회지 Vol.3 No.2

          This study is to research the symbolism of the Eastern and Western costumes' color in films. Therefore, I chose movies about colors, which are 'Trzy Kolory', a Western movie directed by Krzysztof Kieslowski and 'Hero', an Eastern movie directed by Zhang Yimou. The purpose of this study is to figure out the symbolism of the common colors shown in both movie which are red, blue and white. Also, by comparing the eastern and western color symbols I studied the ambivalence of colors. Therefore, the comparison of the eastern and western color symbolisms are as the followings. The color red symbols charity in the movie and jealous, hatless, lies, expansion, self esteem, resist, struggle and sadness in the movie . The color blue symbols freedom, lost, gloomy and sadness in the movie and sacrifice and sadness in the movie . The color white symbols equality and emptiness in the movie and true love, sadness and sacrificed love in the movie . Consequently, it appears that the colors symbolize differently in the East and the West. Three series of which is the West movie has more positive meanings than the Eastern movie. Therefore, the meanings of symbols of the costumes' color are different in the East and West as they have different cultures, and also they could be expressed differently by the directors intention.

          Corynebacterium세균의 이종간 원형질체 융합에 의한 재조합주의 유전학적 분석과 L-glutamate 와 L-glutamine 생성

          백선영,이혜경,최순영,김종욱,이세배,임번삼,민경희 한국산업미생물학회 1990 한국미생물·생명공학회지 Vol.18 No.3

          자외선 조사와 NTG를 처리하여 Brevibacterium flavum 10AHR(arg his Rif^r)과 Corynebacterium glutamicum 11TS(trp Sm^r)의 돌연변이주를 분리하였다. B. flavum 10AHR과 C. glutamicum 11TS를 300㎍/㎖의 lysozyme으로 18시간 처리하여 원형질체를 형성하고, 융합시 30%의 PEG 6,000으로 처리하였을 때 가장 높은 3.7×10 exp(-6)의 융합빈도를 나타내었다. 재조합주의 유전적 분석결과 재조합주들은 FMM(Rif^r Sm^r), FA(Rif^r Sm^r arg), FH(Rif^r Sm^r his), FT(Rif^r Sm^r trp), FAH(Rif^r Sm^r arg his), FAT(Rif^r Sm^r arg trp), FAHT(Rif^r Sm^r arg his trp)으로 분류되었다. FAH에 속하는 균주들은 대부분 모균주에 비해 glutamate와 glutamine의 생산성이 월등히 증가하였으며, FAH1의 경우 glutamate 생성에 있어 모균주인 B. flavum 10AHR에 비해 12배, glutamine은 모균주인 C. glutamicum 11TS에 비해 2.6배 정도 생성이 현저히 증가하였다. 재조합주들의 효소활성을 측정해본 결과 glutamate와 glutamine의 생성량은 GDH와 GS의 활성도와 각각 관련이 있음을 알 수 있었다. For interspecific portoplast fusion, Brevibacterium flavum 10AHR(Rif^r arg his) and Corynebacterium glutamicum 11TS(Sm^r trp) were induced by UV and NTG treatment. The protoplast fusion frequency between B. flavum 10AHR and C. glutamicum 11TS was 3.7×10 exp(-6) with the lysozyme treatment(300㎍/㎖) for 18 hrs. Genotypes of recombinants were analized as FMM(Rif^r Sm^r), FA (Rif^r Sm^r arg), FH(Rif^r Sm^r his), FT(Rif^r Sm^r trp), FAH(Rif^r Sm^r arg trp), FAT(Rif^r Sm^r arg trp), and FAHT(Rif^r Sm^r arg his trp). FAH 1 produced 12 fold of glutamate production compared to parental type, B. flavum 10AHR. In glutamine productivity, it produced 2.6 fold to parental type, C. glutamicum 11TS. Production of glutamate or glutamine by recombinants was involved in the specific activities of glutamate dehydrogenase(GDH) and glutamine synthetase(GS), respectively.

          1930년대 김종량의 H자형 한일절충식 도시주택

          백선영,전봉희 한국건축역사학회 2009 건축역사연구 Vol.18 No.5

          This study investigates H-shaped houses in 1930s and examines the characters and meanings of Kim, Jong-Ryang`s H-shaped houses as a new trial to urban Hanok of those days. He, who was concerned about the housing problem of Seoul, made an attempt to make various types of dwellings. Among them, this study focuses on Japanese-Korean Style H-shaped houses in Samcheong-dong. As the alternative housing type against other urban Hanok of Seoul in 1930s, the H-shaped houses of Kim, Jong-Ryang had characters as follows : 1) H-shaped house has two special characters. First, the whole space of a single house can be divided into a left region and a right region. Second, it can be divided to a front region and a rear region. In his H-shaped houses, the left/right division was expressed as folding of space-layers in parallel with urban streets. The front/rear division was used as classification of main-living space and sub-living space. 2) KJR`s H-shaped Japanese-Korean Style houses were proved to be designed as urban housing against the extreme housing shortage of Seoul in 1930s. 3) His houses however were not accepted broadly as a urban house type because the construction cost of those was higher than an average and the element of Japanese style house was not adapted to Korea. Kim, Jong-Ryang`s trial is valuable because it was the rare case of realization of many discourses as defects of existing house type. With more rigorous investigations on KJR`s experiment in modern house type, we could understand the housing condition of Seoul in 1930s and modern urban houses more than before.

          Potential use of transgenic domestic pigs expressing recombinant human erythropoietin in diabetes translation research

          백선영,정학재,김경운,조규호,최인철,이훈택 한국통합생물학회 2019 Animal cells and systems Vol.23 No.1

          Recently, diabetes mellitus (DM) has shown rapid global increases with about five million deaths annually. Animal models are imperative to understand disease mechanisms and develop diagnostic, preventive, and therapeutic interventions in translational research. Rodent and minipig models have been established and widely used for DM research. However, domestic pig models are limited in spite of advantages such as pharmacokinetic and physiopathological availability. This study examines the potential use of domestic pigs expressing recombinant human erythropoietin (rhEPO) as disease and therapeutic response models for DM. We previously generated transgenic pigs (n = 16, EPO Tg) in which rhEPO was expressed and circulated in all organs. Thirty-two pigs, including 16 controls, were fed high fat (HF) diets for 42 weeks. Subsequently, blood samples for chemical and metabolic analysis were collected after fasting for 24 h and glucose loading for oral glucose tolerance tests (OGTTs). We found increased activation of the PI3 K/Akt signaling pathway under hypoxic conditions after rhEPO treatment, and HF diet-inducible-obesity in the EPO Tg and control pigs. OGTTs showed lower fasting glucose levels in the EPO Tg pigs than in controls before and after the HF diet, suggesting that rhEPO may affect glucose concentrations. Insulin and C-peptide concentrations responded slowly to glucose administration and returned to initial levels after 2 h. The blood test results suggest that EPO might affect metabolic and chemical components such as glucose, high-density lipoprotein, glucagon, triglyceride, and free fatty acid. Our findings support the use of rhEPO transgenic domestic pigs as model animals for translational DM research.

          초등교사에게 사회 교과서란 무엇인가? -세 교사의 사회 교과서 이야기

          백선영 한국사회과교육학회 2019 시민교육연구 Vol.51 No.4

          This study is a narratives study on the meaning of elementary school social textbooks. The problems with textbook-centered lessons have long been pointed out by researchers. To improve this, the national curriculum has been gradually revised from the 7th curriculum so that teachers' expertise in the curriculum can be realized in the class, but the classes have not changed significantly even now when the 2015 revision was introduced. The local education office also require teachers through training to break away from textbook-centered lessons. Such efforts highlighted the negative aspects of the textbook-centered lessons and emphasized the need for curriculum reconstruction. There is not enough discussion about what textbooks are for teachers. Therefore, I tried to find out the meaning of social textbooks by telling the story of the experiences of elementary school teachers. As a result, three meanings were derived. The meaning of social textbooks was likened to ‘shameful inside clothes', ‘menu boards rather than recipe books' and ‘sound words'. There are limits to the generalization of the meaning based on personal experience, but it will help teachers better understand their experiences in social studies textbooks and classes. 본 연구는 초등학교 교사 3인의 내러티브를 통해 사회 교과서의 의미를 탐구하였다. 전통적인 교과서 중심 수업이 우리 교육에 끼치는 문제점들은 오래전부터 지적되어 왔다. 이를 개선하기 위해 제7차 교육과정부터 점차 교사의 교육과정 전문성이 수업에서 실현될 수 있도록 국가 교육과정이 개정되고 있으나, 학교 현장은 2015 개정이 도입된 지금도 크게 변화하지 않고 있다. 시·도 교육청에서도 연수를 통해 교사에게 교과서에 탈피한 수업을 적극적으로 요구하고 있다. 이러한 노력으로 교과서 중심 수업의 부정적인 측면이 부각되고 교육과정 전문성의 필요성이 강조되기는 하였으나, 정작 교사에게 교과서가 무엇인가에 대한 논의는 부족하다. 따라서 초등학교 교사의 이야기를 내러티브 탐구방법을 통해 분석하고, 사회 교과서가 교사들에게 어떤 의미가 있는지 알아보고자 하였다. 그 결과 세 가지 의미를 도출하였다. 초등교사에게 사회 교과서의 의미는 ‘내보이기 부끄러운 빨간 내복', ‘레시피 북이라기보다는 메뉴판', ‘교과서라는 동음이의어'로 비유되었다. 개인적인 경험에 근거를 두어 그 의미를 일반화하기 어렵다는 한계가 있으나, 사회 교과서와 수업에 대한 교사들의 생각을 좀 더 생생하게 이해하는 데 도움을 줄 것이다. 이를 바탕으로 향후 교과서 개발에 고려해야 할 점과 지역교육청의 사회 교과교육 지원 방안을 제안하였다.

          The purpose of this study was to discover the experiences and changes of the violin student's in the ‘El Sistema Korea' orchestra program. Participating observations, classroom observations, activity journals, group interviews and in-depth interviews with participants in the study, and recordings were taken in order to collect data for this research. The conclusions of this study are as follows. First, ‘El Sistema Korea' orchestra education has allowed students to experience a variety of activities that they have never experienced in a more practical way before, which has contributed to expanding there artistic experience. Second, the ‘El Sistema Korea' orchestra education has improved the students' self-confidence and self-esteem, and these personal changes have produced positive improvements in their social skills. Finally, the students' interest to enjoy music in life, to major in music, and to enjoy art in life improved consistently through the ‘El Sistema Korea' orchestra education. However, despite these positive factors, the opportunity costs to study was a decisive factor in forcing them to abandon their orchestra education. 본 연구는 꿈의 오케스트라 교육을 받은 바이올린 단원의 경험과 변화를 탐색하는 것을 목적으로 하였다. 이를 위해 참여 관찰, 관찰 일지, 활동지, 인터뷰 등의 자료들을 분석한 본 연구의 결과는 다음과 같다. 첫째, 꿈의 오케스트라 교육을 통해 연구 참여자들은 실제적인 방법으로 이전에는 경험하지 못했던 다양한 예술 활동을 경험할 수 있었고, 이는 예술적인 면을 확장시키는 요인이 되었다. 둘째, 꿈의 오케스트라 교육을 통해 단원들은 자신감 및 자존감이 향상되었고, 이러한 개인적 변화를 통해 사회성에도 긍정적인 변화가 나타났다. 셋째, 꿈의 오케스트라 교육을 통해 연구 참여자들은 삶에서 예술을 향유하고자 하는 변화가 나타남을 확인할 수 있었다. 그러나 이러한 긍정적인 요인들과는 달리, 단원들에게 학업의 기회비용은 꿈의 오케스트라 교육을 포기하게 하는 결정적인 요인이 되고 있었다.
