This study was conducted to investigate the taxonomic composition and diversity of fecal microbiota between birth and weaning stages of Halla horses using 16S rRNA gene amplicon sequencing analysis. Proteobacteria (35.7%) and Firmicutes (45.6%) were identified as the most common phylum in birth and weaning, respectively. Escherichia (19.7%) and Clostridium (14.0%) were observed as the most dominant genus in birth, and Fibrobacter (6.6%) was the highest in weaning. The results of α-diversity showed that the richness and evenness in microbial communities were statistically significant (p<0.001) in birth and weaning. The results of β-diversity indicated that the birth and weaning stages were clearly divided into two groups at the genus and species levels. Permutational multivariate analysis of variance (PERMANOVA) showed that the microbiota composition differences between birth and weaning were statistically significant (q<0.001). A linear discriminant analysis effect (LEfSe) was performed to select taxonomic makers between the birth and weaning stages. On the genus level, Escherichia, Bacteroides, Clostridium, and Methylobacterium were relatively abundant at birth, whereas Fibrobacter was more abundant at weaning. We expect that this research can be utilized as basic data in the identification of microbial communities involved in disease prevention and nutrient absorption in Halla horses.

1) A process was described for the preparation of drum-dried weaning food containing about 20% protein and based on a blend of sweet potato, full-fat soy flour, minerals, vitamins and methionine. 2) The protein efficiency ratio of this product was 2.63 as compared to 3.30 for the blend containing corn starch in place of sweet potato. This is attributed to the partial destruction of available lysine in the presence of sweet potato during the drum-drying process. 3) Overall nutritive value of the weaning food was comparable to milk food and control food based on corn starch and soy flour in terms of feed efficiency, body composition and protein retention.

This research explores the current situation and determinants of induced abortion in Korea. Using 2000 National fertility Survey by Korea Institute of Health and Social Affairs, this study finds that induced abortion rate is rapidly declining so that the role of induced abortion in determining the level of fertility has disappeared. The fundamental reason for resorting to an induced abortion for Korean women is to avoid unwanted birth. Thus, we find that induced abortion is usually taken by Korean women for the purpose of limiting family size and spacing births as in any other countries. Premarital pregnancy and economic hardship are also important reason for taking an induced abortioin, especially for the first time abortion.

'-느라고'의 후행절 부정 의미 제약에 대하여 연구자들마다 의견을 달리하고 있지만 대부분의 교육 교재는 다수의 연구 내용을 반영하여 '-느라고'의 후행절에 부정 의미 제약이 있다고 제시하고 있다. 하지만 교육 교재에서 후행절에 부정 의미의 제약이 없다는 연구 내용이 배제되어야 한다면 이를 위한 심층적인 논의가 필요하며 타당한 근거가 있음을 밝혀야 한다. 본 연구는 '-느라고'의 후행절 부정 의미 제약에 대해 상반된 주장이 나오게 된 것에 주목하여 실제로 '-느라고'가 후행절 부정 의미 제약을 갖는지, 만약 제약을 갖지 않는다면 그 이유는 무엇인지 밝히고자 하였다. 이를 위해 세종 문어 원시 말뭉치에서 '-느라고'의 문장 1,601개를 추출하고 혹시 있을지 모를 통시적 변화를 제거하기 위해 교육 교재들이 집필된 2000년대의 문장만 선별하여 후행절의 의미를 확인하였다. 그 결과 323개의 문장 중 98개 문장, 33.3%가 후행절에 부정적인 의미를 갖지 않고 있는 것을 확인되었다. 이는 '-느라고'가 단순히 후행절 부정 의미 제약을 갖는다고 할 수 있는 수치가 아니었다. 부정 제약의 범위를 파악하기 위해 문장의 의미를 살펴 목적의 의미를 갖는 '-느라고'와 이유의 의미를 갖는 '-느라고'로 분류하였다. 이렇게 분류한 '-느라고'의 후행절을 다시 분석한 결과 이유의 '-느라고'에서는 후행절 부정 제약이 실현되고 있었지만 목적의 '-느라고'에서는 부정 제약이 발견되지 않았다. 따라서 '-느라고'가 이유와 목적의 의미를 가지며 이유의 '-느라고'로 실현될 때에만 부정 의미 제약을 갖는다는 보다 심층적이고 구체적인 연구 결과 얻어 냈다.

Recently, as the non-face-to-face environment has developed due to COVID-19 and environmental pollution, the importance of online digital healthcare is increasing, and venture start-ups and activities such as health care, telemedicine, and digital treatments are also actively underway. This study conducted the impact on the acceptability of digital healthcare smartwatches with an integrated approach of the expanded integrated technology acceptance model (UTAUT2) and the behavioral inference model (BRT). The most advanced integrated technology acceptance model for innovative technology acceptance research was used to identify major factors such as utility expectations, social effects, convenience, price barriers, lack of alternatives, and behavioral intentions. For the study, about 410 responses from ordinary people in their teens to 60s across the country were collected, and based on this, the hypothesis was verified using structural equations after testing reliability and validity of the data. SPSS 23 and AMOS 23 were used for research analysis. Studies have shown that personal innovation has a significant impact on the reasons for acceptance (use value, social impact, convenience of use), attitude, and non-use (price barriers, lack of alternatives, and barriers to use). These results are the same as the results of previous studies that confirmed the influence of the main value of innovative ICT on user acceptance intention. In addition, the reason for acceptance had a significant effect on attitude, but the effect of the reason for non-acceptance was not significant. It can be analyzed that consumers are interested in new ICT products and new services, but purchase them more carefully and selectively. This study has evolved from the acceptance analysis of general-purpose consumer innovation technology to the acceptance analysis of consumer value in smartwatch digital healthcare, which is a new and important area in the future. Industrially, it can contribute to the product's purchase and marketing. It is hoped that this study will contribute to increasing research in the digital healthcare sector, which will play an important role in our lives in the future, and that it will develop into in-depth factors that are more suitable for consumer value through integrated approach models and integrated analysis of consumer acceptance and non-acceptance.

지난해 하반기부터 최근까지 양천구 목동 신시가지 단지를 중심으로 집값이 크게 올랐다. 지난 8 · 31 대책의 후폭풍으로 강남을 비롯해 전국의 아파트 시장이 꽁꽁 얼어붙었던 가운데 유독 목동의 집값만 상승 곡선을 그렸다. 그동안 목동의 아파트 값이 강세를 보인 이유와 수요자들의 선호도가 높은 이유등을 분석해보았다.
