This study aims to develop a solution to inter-floor noise complaints by exploring cases of noise complaints between floors and by identifying the demands and needs of the residents. For this purpose, a survey was conducted targeting residents who were sorted into groups depending on their experiences with inter-floor noise. This survey was carried out from June 11, 2014 to June 16, 2014. A total of 100 copies of the questionnaire was distributed to the residents, of which 98 were completed and collected. Data were statistically processed in accordance with SPSS WIN 18.0. The results showed that the leading causes of inter-floor noise complaints were residents' differences in schedules and their inconsideration in behavior. Thus, the solution to this issue is three-fold: first, to take social measures in order to improve communication and understanding between residents so they can be mindful of their noise levels; second, to reinforce noise control regulation; and third, to improve noise reduction design within the building architecture.

본 연구의 목적은 실제적 지식 및 기술, 반성적 숙의를 강조한 특수교육관련 교과목 수강에 따른 예비유아교사들의 장애 및 통합교육에 대한 경험적 표상의 변화가 어떠한지를 분석하는데 있다. 연구 참여자는 C대학교 유아교육과 3학년 학생 총 106 명이었으며, 이들을 대상으로 2016년 9월 1일부터 12월 15일까지 장애 및 통합교육에 대한 이미지 및 단어 표상 자료를 수집하였다. 연구 결과, 특수교육관련 교과목 수강에 따른 예비유아교사의 장애에 대한 경험적 표상 변화는 ‘타자화를 벗어나기’ 로 나타났다. 구체적 하위범주로는 첫째, ‘물화된 구분에서 가치의 보편성으로’, 둘째, ‘감정적 연민에서 존재에 대한 인정으로’, 셋째, ‘나와 무관한 사람에서 서로 다가가야 하는 사람으로’로 나타났다. 둘째, 특수교육관련 교과목 수강에 따른 예비유아교사의 통합교육에 대한 경험적 표상 변화는 ‘공존과 상생을 위한 의식적 노력’으로 나타났다. 구체적 하위범주로는 첫째, ‘꺼려지는 것에서 함께여서 발휘되는 가치의 추구’로, 둘째, 단순한 배치에서 본연의 다양성을 위해 준비되어야 하는 환경으로’, 셋째, ‘막연한 두려움에서 실천에 대한 자신감과 의지’로 나타났다. 이러한 연구결과는 유아교육현장에서의 통합교육의 확대 및 보다 바람직한 통합교육 실행을 위한 교사 교육의 방향을 제시하기 위한 기초적 자료를 제공할 수 있을 것이다. The purpose of this study was to examine what changes pre-service early childhood teachers underwent in empirical representation on disabilities and inclusive education by taking courses that were related to special education and put emphasis on practical knowledge, skills and reflective deliberation. The subjects in this study were 106 selected early childhood education students who were in their third year at a college. Data were collected from September 1 to December 15, 2016. Their images of disabilities and inclusive education were collected, and words that they used to represent disabilities and inclusive education were gathered as well. As a result of analyzing the collected data, the change that the pre-service early childhood teachers experienced in empirical representation on disabilities after taking the courses related to special education was escaping from otherness . And there were three subcategories: From reified discrimination to the universality of value , from pity to recognition , and from someone who doesn t concern me to someone to whom I should reach out . The change in their empirical representation on inclusive education after taking the courses related to special education was intentional endeavor for coexistence and co-living . And there were three subcategories: From something to mind to seeking value that can be embodied by coming together , from simple arrangement to environments that should be prepared to ensure diversity , and from vague fear to confidence and will for practice . The findings of the study are expected to provide information on how to provide teacher education to guarantee the successful spread and fulfillment of inclusive early childhood education.

언어경관은 특정 장소의 공공 표지판, 간판 등에 쓰인 언어가 주는 시각적 인상으로, 해당 지역의 인구 구성 및 각 언어 집단 간 사회문화적 지위를 반영한다. 서울은 대부분의 장소에서 한국어와 영어가 지배적인 언어경관이 나타나지만, 상대적으로 외국인이 밀집한 일부 지역에서는 중국어를 비롯한 다른 언어의 비중도 비교적 높게 나타난다. 본 연구에서는 서울 여러 지역의 언어경관을 수집하여 정량적으로 기록하고, 언어경관에 나타난 중국어 비율이 연도별, 지역별로 어떻게 다른지 살펴봄으로써 서울시 중국어 사용 인구의 공간적 분리 수준을 간접적으로 살펴보고자 한다. 지금까지 조선족을 비롯한 중국 국적인의 공간적 분리에 관한 연구는 대부분 거주지 중심으로 이루어져 왔다는 점에서 다소 한계가 있었다. 언어경관의 변화는 거주지뿐만 아니라, 이들이 일상적으로 방문하고 활동하는 상업공간에서도 나타나기 때문에 공간적 분리를 다각도로 살펴보는 데 보다 유용할 수 있다. 분석 결과, 본 연구에서는 서울에서 중국어 사용 인구의 공간적 분리가 지속적으로 감소했음을 확인했으며, 이는 언어경관에 반영된 지리적 현상을 실증적으로 연구한 사례로 학문적 의미가 있다. Linguistic landscape refers to a visual impression of the languages used in public signs and advertisements in a particular area. As it reflects the population composition and the socio-cultural status among language groups in the society, the linguistic landscape of Seoul has been dominated by Korean and English in most places. However, other languages, such as Chinese, also appears in certain parts of the city, where the foreign population is concentrated, and their proportions are increasing in recent years. In this work, we examine the levels of segregation between the Chinese language and other languages in Seoul"s linguistic landscape. Over 10 thousand street-level images were collected and analyzed, and it was found that the levels of the linguistic isolation have decreased over the years between 2008 and 2018. This result implies that the overall degree of segregation between Chinese and non-Chinese people has also moderated, not only in residential neighborhoods but also in their daily activity spaces.

Micro-algae are unicellular photosynthetic organisms and produce pigments such as chlorophyll and carotenoid. Chlorella containsa lot of protein and functional components like lipids, chlorophyll and carotenoids. In this study we induced mutants of Chlorella vulgaris (C. vulgaris) through ultraviolet radiation (UV-B) and selected two mutants by pigment (chlorophyll and carotenoids) content. We named the mutants ‘UBM1-2’, ‘UBM2-57’ and they were cultivated for 21-days. Cell growth, dry cell weight, protein content, lipid and pigments content were measured. The results indicated that the mutants displayed slower cell growth, lower dry cell weight and protein content than the wild type. However, for UBM1-2 the lipid content was 21% higher than the wild type. In addition, the mutants’ chlorophyll content was 37% and 89% higher than the wild type and the carotenoids content was 27% and 70% higher than the wild type, respectively.

This study used a questionnaire survey to investigate the leisure lifestyle and fashion consumption of Korean women in the baby boomers generation (born from 1955 to 1963) living in Changwon city. The Survey period was from October 23 to December 5, 2020. The questionnaire items asked about demographic characteristics, interested in leisure lifestyle, fashion consciousness, and fashion consumption. Data from 250 respondents were analyzed using IBM SPSS Statistics26 to identify the mean, standard deviation, and frequency of the item responses, which were given on a 5-point scale. The participants were involved in economic activity and have a high level of education. They reported having active lifestyle in sports, religious, and social gatherings. The main survey results are as follows; First, many participants were active in economic activities, and their leisure activities were characterized by a high proportion of health-related outdoor activities such as walking, trekking, and mountain climbing. Second, they were more likely to make purchases in-person than online i.e., the number of fashion product purchases made through the Internet and mobile phones was very low. Third, although the women were passive in following and expressing themselves in fashion, they show a conservative tendency due to the large influence of purchases made on the advice of family and acquaintances. Fourth, they considered practicality and quality very important when purchasing clothes. The survey results are expected to help the fashion industries with production planning and to contribute to local research on Korean active senior women.

환경 스트레스는 식물의 성장을 저해하며 작물의 생산량을 감소시키는 주요 원인이다. 식물은 다양한 유전자의 발현 변화를 통해 스트레스에 대한 저항성을 나타낸다. 본 연구에서는 activation tagging system을 이용하여 기존에 밝혀지지 않은 새로운 고염 스트레스 반응 유전자들을 분리하였다. 애기장대의 발아 단계에서 고염 스트레스에 저항성을 보이는 9개의 activation tagging 라인을 선별하였다. 그 중 TAIL-PCR 방법을 이용하여 AT7508, AT7512, AT7527, AT7544, AT7548, AT7556의 6개 라인에서 T-DNA가 삽입된 위치를 확인하였으며 각 라인에서 T-DNA가 삽입된 주변 유전자의 발현을 RT-PCR로 분석하였는데 AT7508, AT7512, AT7527, AT7544, AT7556에서 각각 ClpC2/HSP93-III (At3g48870), plant thionin family (At2g20605), anti-muellerian hormone type-2 receptor (At3g50685), vacuolar iron transporter family protein (At4g27870), microtubule-associated protein (At5g16730)이 activation 된 것으로 밝혀졌다. 더불어 AT7548에서는 T-DNA가 삽입된 곳의 양쪽에 위치하는 두 유전자인 Arabinogalactan protein 13 (AGP13) (At4g26320)과 F-box/RNI-like/FBD-like domains-containing protein (At4g26340)이 모두 activation 되었다. Activation 된 7개 유전자는 기존에 고염 스트레스 저항성과 관련된 기능이 알려지지 않은 유전자로 본 연구를 통해 새롭게 고염 스트레스 반응에 대한 기능이 밝혀졌다. 7개의 activation된 유전자 중 ClpC2/HSP93-III, AGP13, F-box/RNI-like/FBD-like domains-containing protein의 3개 유전자는 고염 스트레스에 의해 발현이 증가하였다. 또한 AT7508과 AT7527, AT7544 라인은 발아 단계뿐만 아니라 유식물체발달 과정에서도 고염 스트레스 저항성을 보여 activation tagging 라인의 선별 결과의 타당성을 뒷받침 하였다. 본 연구의 결과를 통해 activation tagging system이 새로운 스트레스 반응 유전자를 찾아낼 수 있는 유용한 기술임을 확인할 수 있었다. Abiotic stresses limit the growth and productivity of plants. Cellular adaptation to abiotic stresses requires coordinated regulation in gene expression directed by complex mechanisms. This study used the activation tagging system to identify novel salt stress-responsive genes. The study selected 9 activation tagging lines that showed salt stress-tolerant phenotypes during their germination stages. Thermal asymmetric interlaced-PCR (TAIL-PCR) was used to identify the T-DNA tagging sites on the Arabidopsis genome in selected activation tagging lines, including AT7508, AT7512, AT7527, AT7544, AT7548, and AT7556. RT-PCR analysis showed that ClpC2/HSP93-III (At3g48870), plant thionin family (At2g20605), anti-muellerian hormone type-2 receptor (At3g50685), vacuolar iron transporter family protein (At4g27870), and microtubule-associated protein (At5g16730) were activated in AT7508, AT7512, AT7527, AT7544, and AT7556, respectively. Interestingly, in AT7548, both the genes adjacent to the T-DNA insertion site were activated: Arabinogalactan protein 13 (AGP13) (At4g26320) and F-box/RNI-like/FBD-like domains-containing protein (At4g26340). All of the seven genes were newly identified as salt stress-responsive genes from this study. Among them, the expression of ClpC2/HSP93-III, AGP13, F-box/RNI-like/FBD-like domains-containing protein gene, and microtubule-associated protein gene were increased under salt-stress condition. In addition, AT7508, AT7527, and AT7544 were more tolerant to salt stress than wild type at seedling development stage, functionally validating the screening results of the activation tagging lines. Taken together, our results demonstrate that the activation tagging system is useful for identifying novel stress-responsive genes.
