This study was conducted to investigate the effect of addition levels of coffee and green tea by products extract including polyphenols through hot water extraction on rumen fermentation. The treatment groups consisted of coffee extract (CO), green tea extract (GR) and mixed extract (MIX), and the addition level was 10 μL, 20 μL and 30 μL of three levels. The experiment consisted of a total of 10 experimental groups including the control group, and a full factorial design was used. The effect of polyphenol addition in coffee and green tea by-products was analyzed through main and interaction effect of statistical analysis. The total polyphenol content of the extracts was 106.15, 79.10 and 185.25 μg GAE/g DM for coffee by-product, green tea by-product and mixture, respectively. Total gas production was significantly lower in the treatment groups than in the control (114.00 mL/gDM) (p<0.05). Methane emission tended to decrease as the polyphenol addition level increased. Moreover, the MIX showed the lowest methane emission when 30 μL was added (p<0.05). Volatile fatty acids showed a significant difference compared to the treatment group as a control (98.06 mM) (p<0.05), but there was no change according to the level of polyphenols. As a result of the main effect and interaction, it is thought that the effect on methane reduction and improvement of rumen fermentation in MIX20 can be expected. In a series of studies, the addition of 20 μL of a blended extract of coffee and green tea by-products is thought to reduce methane to levels that do not inhibit rumen fermentation.

경기도 지자체 도시브랜드 이미지 제고를 위한 CI, BI, VI 차별화에 관한 연구

류미영 ( Ryu¸ Miyoung ),장영호 ( Jang¸ Youngho ),김주연 ( Kim¸ Jooyun ) 한국공간디자인학회 2021 한국공간디자인학회논문집 Vol.16 No.7

(연구배경 및 목적) 경제 구조와 사회 변화로 도시의 중요성이 강조되자 지자체는 도시를 인식하고 기억하기 위해 CI나 BI, 캐릭터, 마스코트 등 도시브랜드를 만들어 상징물로 관리하고 있다. 다른 지자체와 차별화된 도시정체성이 잘 반영된 상징물은 지자체의 큰 자산이므로 다투어 상징물을 개발하고 있으나, 경계가 모호한 CI. BI, VI 개발로 지자체 안에서도 차별화되지 않는 실정이다. 본 연구는 지자체 상징물 중 CI와 BI, VI 등의 현황 분석을 통해 수요자의 아이덴티티 혼동 가능성과 지자체 간 비차별화의 문제점을 밝힘으로 향후 지자체가 상징물을 개선하거나 새롭게 개발할 때 고려해야 할 관점을 제시하는 데 목적이 있다. (연구방법) 시, 군 등의 경기도 지자체 31곳 홈페이지에 게시된 CI, BI, VI 현황을 조사해 CI와 함께 BI나 VI가 있는 지자체는 심벌, 심벌마크와 로고타입, 워드마크 등 시각 아이덴티티 구성 요소를 비교 분석하였다. 이와 함께 적용 범위, 관리부서를 정보 공개 요청해 지자체 상징물이 실제로 어떻게 활용되는지 조사하고, 혼동의 개념과 혼동 이론, 브랜드 혼동을 지자체와 연관해 시각 구성 요소가 혼동을 일으키는 이유를 고찰하였다. (결과) 경기도 지자체는 CI, BI, VI 등의 상징물이 있으며 시각 아이덴티티 구성 요소가 다양하다. CI, BI, VI를 같은 부서에서 관리하거나 다른 부서에서 관리하기도 하며, 적용 대상이 같거나 다르고 그 경계가 명확하지 않으며 각 지자체 마다 적용 범위가 다르다. (결론) CI, BI의 시각 아이덴티티 구성 요소인 로고타입은 특정 글 자체로 만들어 상표 기능을 겸한 상징적 형태임에도 불구하고 서로 다른 글자체로 만들어 상표의 상징적인 기능이 낮아지는 경향이 있다. BI가 지자체 명칭이거나 다른 수식어가 붙는 워드마크인 경우는 CI와 시각적으로 구분되지만, CI와 같은 심벌 및 심벌마크와 로고타입의 시각 구성 요소인 경우에는 CI와 혼동될 가능성이 높다. 각 지자체마다 CI, BI의 적용 범위가 다르고 한 지자체 안에서 CI와 BI, VI가 범위 경계 없이 같이 적용하는 경우도 있어 혼동될 가능성이 있다. 이러한 문제점을 바탕으로 지자체가 상징물을 개선하거나 새롭게 개발할 때 고려해야 할 관점은 다음과 같다. 첫째, 도시브랜드의 이미지 제고를 위해서는 지자체를 대표하는 상징으로 정체성을 확립해야 한다. 둘째, CI와 BI, VI의 적용 범위 등을 구분할 필요가 있다. 셋째, CI가 있는 지자체가 BI를 새롭게 개발할 경우 수요자가 CI와 시각적으로 혼동하지 않도록 고려해야한다. 이는 다른 지자체와의 차별화된 정체성을 확립하기 위해 만든 상징물이 한 지자체 안에서도 혼동된다면 타 지자체와 차별화를 기대하기 어렵기 때문이다. (Background and Purpose) As cities’ importance is emphasized because of economic structure and social change, local governments create city brands such as CI, BI, characters, and mascots, to recognize and remember the city and manage them as symbols. Differentiated symbols reflecting city identity are competitively developed as large assets of local governments; however, they are not differentiated within local governments because of the development of CI, BI, and VI, whose boundaries remain unclear. This study proposes perspectives to be considered for future symbols renewal or development by identity confusion in user perspective and non-differentiation among local governments through CI, BI, and VI analysis. (Method) To survey the status of CI, BI, and VI posted on homepages of 31 local governments in Gyeonggi-do, comprising cities and counties, and to compare and analyze visual identity components, such as symbol, symbol mark, logotype, and wordmark, when BI and VI are with CI. Furthermore, information on coverage and management to investigate actual usage was sought; additionally, the reasons why visual components are unclear, concerning the concept of confusion, confusion theory, and brand confusion, were considered. (Results) Gyeonggi-do local government has symbols such as CI, BI, and VI, and there are various elements of visual identity managed by the same or different departments, that are governed by the same or different coverage, with unclear boundaries, and different local governments. (Conclusions) Logotype, a component of CI and BI visual identity, is created in a particular typeface and acts as a trademark, but is made in different typeface, resulting in less symbolic functionality. If BI is the name of a local government or a wordmark with other modifiers, it is visually distinguished from CI; however, in the case of symbols such as CI and visual components of symbol mark and logotype, it is highly likely to be confused with CI. Whereas the scope of application of CI and BI is different for each local government, CI, BI, and VI are not differentiated and are sometimes applied together, thus causing confusion. Based on these problems, local governments should consider the following perspectives when renewing or developing new symbols. First, enhancing the image of the city brand, the identity as a symbol representing the local government should be established. Second, it is necessary to distinguish the scope of application of CI, BI, and VI. Finally, local governments with CI should not be visually confused with CI by users when developing a new BI. This is because it is difficult to expect differentiation from other local governments if symbols created to establish differentiated identity from other local governments are confused even within one local government.

( Miyoung Jang ),( Dal Lae Ju ),( Meera Kweon ),( Misun Park ) 한국임상영양학회 2016 Clinical Nutrition Research Vol.5 No.4

Diabetes in pregnancy is associated with higher rates of miscarriage, pre-eclampsia, preterm labor, and fetal malformation. To prevent these obstetric and perinatal complications, women with diabetes have to control levels of blood sugar, both prior to and during pregnancy. Thus, individualized medical nutrition therapy for each stage of pregnancy is essential. We provided in-depth medical nutrition therapy to a 38-year-old pregnant woman with diabetes at all stages of pregnancy up to delivery. She underwent radiation therapy after surgery for breast cancer and was diagnosed with diabetes. At the time of diagnosis, her glycated hemoglobin level was 8.3% and she was planning her pregnancy. She started taking an oral hypoglycemic agent and received education regarding the management of diabetes and preconception care. She became pregnant while maintaining a glycated hemoglobin level of less than 6%. We provided education program for diabetes management during the pregnancy, together with insulin therapy. She experienced weight loss and ketones were detected; furthermore, she was taking in less than the recommended amount of foods for the regulation of blood sugar levels. By giving emotional support, we continued the counseling and achieved not only glycemic control but also instilled an appreciation of the importance of appropriate weight gain and coping with difficulties. Through careful diabetes management, the woman had a successful outcome for her pregnancy, other than entering preterm labor at 34 weeks. This study implicated that the important things in medical nutrition therapy for pregnant women with diabetes are frequent follow-up care and emotional approach through the pregnancy process.

With the recent increase in the number of social robots, expectations from robot technology are increasing daily. In particular, the development of cognition technology using deep learning has enabled various services, leading to the expansion of the robot market. However, in a dynamic real environment, robot object recognition requires the concept of intelligence rather than performance. In this study, we constructed an object recognition intelligence evaluation model based on the visual perception of humans. Then, we evaluated the object recognition intelligence of a social robot using a scenario based on this model.

A New Query Integrity Verification Method with Cluster-based Data Transformation in Cloud Computing Environment

Miyoung Jang,Min Yoon,Jae-Woo Chang 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.4

Due to advancement in cloud computing technology, the research on the outsourced database has been spotlighted. In database outsourcing, because the service provider might be untrusted or compromised, two issues of data security emerge: data confidentiality and data integrity. Many data transformation schemes were widely studied for preserving data confidentiality, but they are vulnerable to data leakage problem because they do not consider data distribution when encrypting original data. Meanwhile, several query authentication schemes were proposed to verity data integrity, but they suffer from transmission overhead of verification data. Motivated by these problems, we propose a privacy-aware query authentication scheme which guarantees the data confidentiality and the query result integrity of sensitive data. To solve the original data leakage problem, our clustering-based data transformation scheme is designed to select anchors based on data distribution. To verify the query result, we propose a query result authentication index that stores an encrypted signature for each anchor, which is a concatenated hash digest of cluster data. A user compares the verification information with the cluster signatures stored in the verification index. Through performance evaluation, we show that our method outperforms the existing method in terms of query processing time and verification data size.

Miyoung Yang, Hyosun Jang, Hae-June Lee, Changjong Moon, Jong-Choon Kim, Jong-Sik Jang, Uhee Jung, Sung-Kee Jo, Sung-Ho Kim 충북대학교 동물의학연구소 2014 Journal of Biomedical and Translational Research Vol.15 No.1

Panax ginseng, also known as Korean ginseng, has long been used as a broad tonic in Oriental medicine to augment vitality, health, and longevity, particularly in older people. This study investigated the effects of Korean red ginseng (RG) on bone loss in ovariectomized (OVX) mice. C3H/HeN mice (10-weeks-old) were divided into sham and OVX groups. OVX mice were treated with vehicle, 17β-estradiol (E2), RG (oral administration, 250 mg/kg/day), or RG (intraperitoneal administration, 50 mg/kg/every other day) for 6 weeks. Serum E2 concentration and alkaline phosphatase (ALP) activity were measured. Tibiae were analyzed using microcomputed tomography. Biomechanical properties and osteoclast surface level were measured. There was no significant difference in the degree of grip strength, body weight, uterine weight, mechanical property, tibiae length, or tibiae weight between the OVX and RG-treated groups. Compared with the OVX group, the serum ALP level was significantly lower in the RG-treated groups. Serum E2 levels and osteoclast surface levels did not change between the OVX and RG-treated groups. RG could not preserve trabecular bone volume, trabecular bone number, trabecular separation, trabecular thickness, structure model index, or bone mineral density of the proximal tibiae metaphysic. In conclusion, there was no definite effect of RG on OVX-induced bone loss in C3H/HeN mice.

장미영 ( Miyoung Jang ) 시학과 언어학회 2015 시학과 언어학 Vol.31 No.-

본 연구는 대학생 학습자의 쓰기 지도를 위해 제공되어야 할 매체텍스트 중 전략적으로 내용 생성을 극대화 하고, 사고력을 향상시킬 수 있는 다중매체텍스트 활용방안을 모색하는 것을 목적으로 한다. 대학생들이 대학에서 학습하는 글쓰기 갈래와 주제는 다양하다. 글쓰기 수업 중 학습자가 느끼는 어려움은 글쓰기에 관한 이론의 부족이나 형식을 이해하지 못한 경우 각 형식에 맞는 글쓰기 절차와 서술방법을 실습하는 가운데 원리를 터득할 수 있다. 그러나 내용 생성하기의 경우 주어진 텍스트 분석과 주제에 대한 이해는 물론 본문의 내용 생성 어려움을 호소하는 경우가 많다. 수업 중 제시되는 주제나 갈래에 맞는 글쓰기를 효과적으로 수행하기 위해서는 학생이 알고 있는 배경지식과 다양한 관점의 정보가 추가되어야 한다.본 연구는 글쓰기 교육에서 다중매체텍스트를 활용할 경우 유효한 정보와 다양한 관점의 지식을 학습자에게 제공할 수 있고, 직접적으로 내용생성 뿐만 아니라 학습자가 타당한 판단을 내리는데 도움이 된다는 전제에서 출발하였다. 수업과정에서 교수,학습 매체의 활용은 학습자에게 글쓰기에 대한 흥미를 고양하고, 교수자의 교육 목표를 직접적으로 전달 할 수 있는 효과적인 교수법 중 하나이다. 그러므로 다중매체텍스트의 활용은 텍스트 사이의 상호텍스트성을 통해 주제를 좀 더 폭넓고 깊이 있게 이해할 수 있는 토대를 제공하게 된다. 한 가지 주제에 대한 다양한 텍스트의 제공은 지식, 정보전달의 목적을 넘어 교수자와 학습자, 학습자와 학습자, 학습자와 매체 사이에서 빈번히 이루어지는 의사소통과정을 포함하게 된다. 학습자는 수업의 객체가 아닌 주체로서 능동적으로 참여하게 되고 교수자와 학습자 사이의 상호작용은 타인을 이해하고 공감하는 경험을 제공하게 된다.다중매체텍스트를 활용한 글쓰기 교육은 글쓰기 수업 시간은 물론 대학생이 느끼는글쓰기 관련 문제점을 개선하고 학습자의 사회에 대한 이해의 폭과 깊이를 확대할 것으로 기대한다. The purpose of this study is to examine intertextuality model,which maximizes textual resources and activates ability of thinking,as an instruction for college students to write texts. Whereas college students have been offered variable writing subjects and theories,they have problems in creating texts. It is necessary for students to be provided new knowledge in order to connect prior knowledge on a topic. In this study, intertextuality is introduced as an approach which is beneficial to provide students with useful information and knowledge as well as allow students to construct text. In the class,the effects of teaching-learning media is various, and also method and scope of utilization is being used differently according to objection. In this regard, intertextuality is not only provides knowledge and information but also binds instructors with learners,learners with media and among learners as a process of communication. It helps learners to engage in writing class as an agent, interact with instructors which influences the way learners perceive the world around them.As a result, it is expected that intertextuality approach in writing both improves problems in writing class and offers learners an opportunity to broaden understanding in the community.
