현재까지 국내의 학자들에 의해 소, 돼지, 닭 등 일반가축에 대한 연구는 상당한 수준까지 진척되어 왔으나 양록업이 상업화된지 약 30년이 지난 현재까지 국내에서 사육되고 있는 사슴에 대해서는 사양표준은 커녕 일반 연구조차 수행된 적이 없고 더우기 국내 양록업에 대한 정확한 통계자료마저 조사된 것이 없어 1989년 말 현재 국내에서 사육되고 있는 8만여두에 이른 사슴을 각 사육농가에서는 연구기관의 기술적 지원이나 정부당국의 양록에 대한 정책 배려도 없이 사육농가 나름대로의 기술에 의해 실패를 거듭하면서 사육해 오고 있는 실정이다. 1980년대 초반까지만 해도 일반의 인식은 양록업이 부유층의 사치산업으로 인식되어 왔고 사슴의 생산물이라 할 수 있는 녹용도 부유층의 전유물로 생각된 적도 있으나 최근에 와서는 사슴사육농가도 늘고 사육두수도 증가함에 따라 특별한 가축으로 인식되어지기 보다는 축산으로서의 비중이 증가되고 있는 것이 현실인데 양록협회(1998)의 보고에 의하면 1995년에는 사슴사육두수가 35만두로 증가될 것을 예상하고 있어 이에 대한 기초적인 연구와 함께 축산으로서의 양록에 대한 장기적인 안목에서의 정책배려가 이루어져야 할 것으로 생각된다. 본 조사에서는 앞으로 이루어질 사슴사육에 관한 연구의 기초방향을 제시하는데 목적을 두고 현재 국내 양록농가에서의 수엽류 이용실태를 조사하여 이에 대한 기초연구를 수행하는데 도움을 얻고자 본 조사를 수행하였다. 아울러 본 조사에 성의껏 응해주신 양록인들께 깊은감사를 드리며 지면으로 인사드리게 된 것을 죄송하게 생각합니다.

2021년에 발생한 일련의 소프트웨어 공급망 공격으로 미국 연방 정부의 사이버보안 개선 정책이 가속됐다. 이중 소프트웨어 구성 정보를 유통하는 SBOM 정책은 SW 구성요소의 투명성을 강화하여, 이를 활용하는 공급자와 수요자의 보안 인식 개선에도 도움을 줄 것이 기대된다. 다만 SBOM으로 공급망 보안 위협을 완화하려면 해결해야 할 기술적 이슈가 있고, SBOM 수집자를 위한 구체적인 가이드도 마련되지 않아 제도 정착에는 시간이 걸린다. SW 공급망 문제는 SW 개발 관행에 대한 지속적인 개선이 요구되며, 글로벌 연쇄 위험으로 결코 혼자서는 해결할 수 없다. 따라서 우리는 실태조사, 실증사업 등을 시작으로 현실에 맞는 정책을 먼저 적용하고, 제도적 조화를 위한 국제협력에도 힘써야 한다.

Sequence-to-sequence deep neural networks with attention mechanisms have shown superior performance across various domains, where the sizes of the input and the output sequences may differ. However, if the input sequences are much longer than the output sequences, and the characteristic of the input sequence changes within a single output token, the conventional attention mechanisms are inappropriate, because only a single context vector is used for each output token. In this paper, we propose a double-attention mechanism to handle this problem by using two context vectors that cover the left and the right parts of the input focus separately. The effectiveness of the proposed method is evaluated using speech recognition experiments on the TIMIT corpus.

During meiosis, genetic recombinants are formed by homologous recombination accompanying with the programmed double-strand breaks (DSBs) and strand exchanges between homologous chromosomes. The mechanism is generated by recombination intermediates such as single-end invasions (SEIs) and double-Holliday junctions (dHJs), and followed by crossover (CO) or non-crossover (NCO) products. Our study was focused on the analysis of meiotic recombination intermediates (DSBs, SEIs, and dHJs) and final recombination products (CO and NCO). We identified these meiotic recombination intermediates using DNA physical analysis under HIS4LEU2 "hot spot" system in budding yeast, Saccharomyces cerevisiae. For DNA physical analysis, when the hot spot locus is recognized by restriction enzyme from synchronous meiotic cells, the fragmented DNA that are forming recombination intermediates can be detected and quantified through Southern hybridization analysis. Our study suggests that this system can analyze the structural change of recombination intermediates during DSB-SEI transition, double-Holiday junctions and crossover/non-crossover products in meiosis.

컴퓨터의 보편화와 멀티미디어의 발전으로 많은 인공지능의 분야들이 실생활에 응용되고 있다. 이중에서 얼굴 인식은 최근에 연구가 활발한 분야 중의 하나이며 인터넷 또는 멀티미디어를 통한 보안 시스템 등에서 많은 응용이 기대되고 있다. 이러한 이유로 향후 얼굴인식이 차지하는 비중은 더욱 커질 것으로 예상된다. 본 논문에서는 조명에 대한 환경 변화에 덜 민감한 시스템을 구현하기 위하여 주성분 분석(PCA: Principal Component Analysis)과 가보 제트(Gabor jet)에 환경 파라미터를 추가하여 병렬적으로 수행하는 얼굴 인증시스템을 구형 하였다. 실험을 통하여 기존의 주성분 분석이나 가보 제트 만을 이용한 얼굴인식 알고리즘 보다 환경 변화에 덜 민감하고 오 인증률이 저하된 결과를 나타낸 것을 알 수 있다.

Utilizing a qualitative multimethod approach, this study was to discover and improve the understanding of occupational socialization process of librarians. Through theoretical sampling, 42 participants were in-deathly interviewed at three studies, i.e phenomenological, ethnographic, and grounded theory approach. Analyzed data were finally integrated using grounded theory approach. 'Acquiring Social Recognition as an Information Professional' was emerged as the core category for describing and guiding the occupational socialization process. A seven-stage process was discovered: 'Adapting', 'Experiencing being the Periphery', 'Perceiving the Role', 'Pursuing the advancement', 'Realizing the professionality', 'Rediscovering the Value', and 'Showing the Professionality'. Especially, 'Experiencing being the Periphery' was identified as a critical and unique process, reflected the perceived status of librarians in Korea. Also, it discussed characteristics and socialization strategies of the process.

This study is a basic research to apply ESD linked to SDGs to pre-service teachers majoring in earth science education. The purpose of this study is to evaluate carbon literacy by analyzing the awareness, attitude and knowledge, subjective norms, and behavioral control of the carbon footprint internalized by pre-service teachers. Pre-service teachers recognize the carbon footprint as their responsibility, but are not willing to pay the cost and accept inconveniences of the actions to reduce carbon footprint. They also support actions to reduce carbon footprint, but do not demand the actions from others. While they have sufficient knowledge about carbon mitigation actions, their conception of causes and effects of global warming is unstable. Pre-service teachers will go out to school sites and teach millions of students about global warming. It is essential to educate these teachers on the economic cost and social responsibility of reducing their carbon footprints. It is also important to find ways to bridge the gap between their thought and action. It is hoped that this study on pre-service teachers' carbon literacy will lead to realizing ESD.

This paper proposes a novel recognition model, a recurrent fuzzy associative memory(RFAM), for recognizing time-series patterns contained an ambiguity. RFAM is basically extended from FAM(Fuzzy Associative memory) by adding a recurrent layer which can be used to deal with sequential input patterns and to characterize their temporal relations. RFAM provides a Hebbian-style learning method which establishes the degree of association between input and output. The error back-propagation algorithm is also adopted to train the weights of the recurrent layer of RFAM. To evaluate the performance of the proposed model, we applied it to a word boundary detection problem of speech signal.

This study analyzed a total of 37 studies about bi-lingulism and English education as a foreign language published in 8 academic journals in early childhood education or child development fields. Research topics, participants, methods, and variables in the studies were categorized and descriptively analyzed. The research findings which had been statistically investigated were also summarized. The most frequently studied research topics were children's development and English education program exposure, actual conditions of English education in preschool settings and effectiveness of specific English programs for preschool children. However, children's home characteristics were seldom included as research variables and no research investigated so called English preschools. Several studies reported that bi-lingual children may have different language development paths from mono-lingual children but they eventually have comparable language abilities to mono-lingual children. Also some studies reported that, when learning English as a foreign language in school settings, older children can handle more information regarding English than younger children, resulting in better outcomes of older children. Exposure to two languages in early childhood seems to contribute to young children's meta linguistic awareness but the long term effect of English education in early childhood should be further studied. Several English education programs for preschool settings were developed and the effectiveness were investigated. Even though most of them reported that their programs were effective to children's English ability or interests, the results should be carefully interpreted because their research designs and methods were not rigorous.

This paper suggests how Korean housemaids, called Sikmo, and Korean-Chinese migrant domestic workers have similar class positions and therefore form a dual identity in their interactions with female employers. rough spoken stories of the experiences of 27 females from Seoul, including Korean-Chinese domestic workers, Korean housemaids, and their employers, this research effectively overcomes the dichotomous discourse of natives versus foreigners. Instead it suggests the new interpretation that it is not foreignness but class inferiority of the domestic workers that plays a key role in establishing relationships with employers. Korean housemaids and Korean-Chinese domestic workers, both groups of whom are migrant workers, have developed coping strategies to enhance their labor value by spatially relocating themselves from their home society to a new society. They possess a similar labor status in women's history, being of low income, low education, and rural births. Consequently, these women experience 'translocal anchoring,' meaning their identities are intertwined with that of their home societies, and employers perceive them based on the characteristics of these places. The Korean employers perceive that the domestic workers' morality and intellectuality are inferior based on their class differences. This stigmatizing process leads employers to regard domestic workers as ambivalent people, not only threatening outsiders but also objects of pity, needing love and protection of their employers. The employers educate them culturally, teaching them skills to survive in the urban environment. These skills include cooking and language, in addition to advice on long-term plans to blend into society.
