Taurine is an abundant amino acid in many animals, including humans. Relatively large amounts of taurine are found in leukocytes, heart, muscles, retinas, kidneys, bones, and liver. Taurine has antioxidant effects; it reacts with hydrogen peroxide to prevent oxidation of the cell membrane. Taurine enhances the effects of anticancer drugs, while also reducing side effects, and taurolidine, a taurine derivative, has been shown to exhibit anti-cancer effects without notable side effects in several types of cancer. Taurine aids in cholesterol metabolism by increasing the rate of synthesis of bile acids, and, thus, reduces triglyceride levels. In addition, taurine is involved in the growth and differentiation of nerve cells and is associated with some neurological disorders. Taurine aids in bone formation and prevents bone dissolution. Moreover, taurine prevents liver damage from a variety of drugs and, thus, protects the liver. Taurine is involved in the development and function of the retina and lens. It also has anti-atherosclerotic and anti-thrombotic effects that protect against cardiovascular disease. Taurine may have additional physiological functions, and warrants further investigation.

This paper defines the common features of synbiotics based on the definition of probiotics and prebiotics, and reviews the effectiveness of synbiotic food. The concept of synbiotics is defined as 'a mixture of prebiotics and probiotics that have a beneficial effect on the host, as a dietary supplement that alters living organisms in the gastrointestinal tract and improves their survival.' Synbiotic food contains ingredients with beneficial microbes that are expected to improve interactions between microbial and useful substances. Synbiotic foods may have anti-cancer and immune system-boosting effects. Improved digestion, healthier bowel movements, and overall increased intestinal health has been reported were reported after increasing the healthy microorganisms within the intestinal tract. In addition, depending on the type of food containing the symbiotic ingredients, more consistent weight control, improvement of cardiovascular health, and lower blood glucose levels may also be expected. Unlike previous studies, this review of synbiotics has shown that it is necessary for synergistic effects to take place among microorganisms and components to be further studied. Further research is needed on the safety and ingestion of microorganisms contained in synbiotics.

윤진아,강훈식,Yoon, Jin-A,Kang, Hun-Sik 대한화학회 2011 대한화학회지 Vol.55 No.3

이 연구에서는 초등 과학영재교육에서 소집단 비유 만들기의 효과를 학생들이 만든 비유의 유형과 대응 오류, 소집단 비유 만들기에 대한 인식 측면에서 조사했다. 2개 초등학교의 2개 과학영재학급에 소속된 5학년 학생 37명을 선정하여 각각 개별 비유 만들기(IA) 집단(n=19)과 2인 1조의 소집단 비유 만들기(PA) 집단(n=18)으로 배치했다. 두 집단 학생들에게 첫 번째 시간에 포화용액 개념에 대한 실험과 개념 학습을 실시한 후, 두 번째 시간에 그 개념에 대한 비유 만들기 검사를 실시했다. 또한 PA 집단 학생들에게는 소집단 비유 만들기에 대한 인식 검사를 실시했으며, 일부 학생들을 대상으로 이에 대한 심층 면담도 실시했다. 연구 결과, IA 집단보다 PA 집단의 학생들이 글/그림 비유, 구조적/기능적 비유, 부연 비유, 고체계성 비유를 더 많이 만드는 경향이 있었으나, 상황의 작위성(작위적, 일상적)과 추상도(추상적, 구체적) 항목에서는 두 집단 간에 차이가 거의 없었다. IA 집단보다 PA 집단의 학생들이 대응 오류를 더 적게 범했다. PA 집단의 많은 학생들이 소집단 비유 만들기에 대해 다양한 인지적 동기적 측면에서 긍정적으로 인식했으나, 몇 가지 단점을 지적하기도 했다. 이에 대한 교육적 함의를 논했다. In this study, we investigated the effects of analogy-generating in small group in elementary science-gifted education upon the types and the mapping errors of student-generated analogies, and the perceptions of the instruction. Fifth graders (N=37) at two science-gifted classes in two elementary schools were selected and assigned to individualistic analogygenerating (IA, n=19) and pair analogy-generating (PA, n=18) groups. After the students of each group performed the experiment and were taught about 'saturated solution' concept in the first class, they administered the test on the self-generating analogies on the concept in the second class. The students in the PA group also administered the test on perceptions of analogy-generating in small group and some of them were interviewed deeply. The results revealed that the students in the PA group made more verbal/pictorial, structural/functional, enriched, and higher systematic analogies than those in the IA group. However, there were little difference between the two groups in the subcategories of artificiality (artificial and everyday) and abstraction (abstract and concrete). The students in the PA group fewer mapping errors than those in the IA group. Many students in PA group perceived the analogy-generating in small group positively upon various cognitive and motivational aspects. However, they also pointed a few disadvantages of the activity. Educational implications of these findings are discussed.

윤진아(Yoon Jin-Ah),우희정(Woo Hee-Jeung) 한복문화학회 2011 韓服文化 Vol.14 No.1

The purpose of this study is to research the modern fashion design applying the characteristic of Hanbok. The aesthetic characteristics of Hanbok shown in modern fashion are as follows. The traditional beauty is emphasized by using soft curve shown in silhouette of Korean dress as design point. In addition, natural beauty is expressed by using primary color contrast on the basis of white color and using traditional natural materials such as cotton, wool, silk and linen. By exposing shoulder and emphasizing abundance of layered skirt, Hanbok shows the decorating beauty with various changes and patterns of rhythm, which come from overlapped cloth. The elements of Hanbok applied to modern dress are as follows. For silhouette, hour glass silhouette and straight silhouette are frequent and for material, new materials such as wool, leather, fur and polyester are frequent. For detail, Hanbok-style collar, sleeve, goreum(breast tie) and skirt hem are applied to modern dress. On the basis of the theory above, 3 actual works were manufactured. Through the study, following results were achieved. It was possible to express retro image of new style suitable to the sense of current age by harmonizing elements such as silhouette, material and decoration factor with modern fashion. In addition, it was possible to manufacture the type considering the function of modern life. Especially, by emphasizing function, traditional pattern and material were applied to one side and existing western material and silhouette were applied to another side to enable one dress to give the effect of two dresses. By harmonizing traditional dress and western dress, aesthetic factors such as natural beauty, traditional beauty and decorating beauty were displayed.

연구논문 : 손바닥선인장 복합물이 Streptozotocin으로 유발된 당뇨 쥐의 지질대사에 미치는 효과

윤진아 ( Jin A Yoon ) 한국식품영양학회 2013 韓國食品營養學會誌 Vol.26 No.3

This study was conducted to examine the effects of Opuntia ficus-indica complex (OF) on the lipid metabolism, bile acid in feces, alanine aminotransferase (ALT) activity, aspatate aminotransferase (AST) activity, composition of urine and expression of cholesterol related mRNA in streptozotocin (STZ)-induced diabetic rats. Thirty two male Sprague-Dawley rats were randomly divided into non-diabetic control (NC), diabetic control (DC), diabetic OF of 2% (OF-2) and diabetic OF of 5% (OF-5), then each group was fed for 3 weeks. Plasma total cholesterol, non-esterified fatty acids (NEFA), total cholesterol, low density lipoprotein (LDL), very low density lipoprotein (VLDL) were decreased significantly (p<0.05) in OF-5 group compared to DC, but high density lipoprotein (HDL) was not changed. AST and ALT were also reduced and bile acid excretion was improved. Composition of urine in OF-5 was almost same in NC. The expression of cholesterol 7α-hydroxylase (CYP7A1), 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA-R), Low density lipoprotein receptor (LDL-R) mRNA indicated that feeding OF have the effects of cholesterol decreation in plasma by synthesis of bile acid from cholesterol. These results provide experimental evidence about improved lipid metabolism of the OF feeding in the STZ-induced diabetic rats.

독일에서의 자율주행자동차에 관한 법적 논의

윤진아 ( Yoon Jin-ah ),김상태 ( Kim Sang-tae ) 한양대학교 법학연구소 2017 법학논총 Vol.34 No.1

자율주행자동차 관련하여 입법행위를 적극적으로 하고 있는 미국과는 달리 독일에서는 보다 신중한 입장에서 법적 논의를 진행하고 있다. 자율주행자동차가 도입되었을 경우 현행법 하에서 어떠한 문제가 제기될 수 있는지, 그 해결을 위한 논의는 어떻게 진행되어야 하는지 등 방향성에 대해서만 논의하고 있는 것이다. 그러한 법적 논의를 정리하면 다음과 같다. 첫째, “자동차를 운전하는 사람은 차량을 계속 통제할 수 있는 속도로 운행해야한다”고 규정하고 있는 도로교통규칙(StVO) 제3조 제1항을 비롯한 다수의 법령들이 운전자를 전제로 하고 있어서 독일 내에서의 자율주행자동차의 운행은 현행법상 허용되지 않는다. 따라서 독일에서도 자율주행자동차가 운행되기 위해 가장 먼저, 그리고 가장 근본적으로 논의해야 할 부분이 `운전자`에 관한 규정이라고 보고 이에 대한 논의를 진행하고 있다. 둘째, 독일도 우리나라와 마찬가지로 자동차의 운행 중에 생긴 사고에 대한 책임은 1차적으로 운전자에게 있다. 그러나, 자율주행자동차의 운전자는 본인은 실제로 자동차를 운행하지 않았기 때문에, 법적 책임이 없다고 주장할 수 있다. 운전자는 오히려 `제조물책임법(ProdHaftG)`에 근거하여 자동차 제조자가 법적 책임을 부담하여야 한다고 주장할 수 있다. 하지만, 제조물책임법은 제조물의 결함에 대한 입증책임을 손해를 입은 자에게 부담시키고 있기 때문에, 피해자가 제조물의 결함을 입증하지 못하는 경우 제조자에게 손해배상을 청구할 수는 없다. 결국 이러한 규정들은 자율주행자동차의 소유자, 운전자, 제조자 간의 책임 분배 문제를 매우 모호하게 할 수 있다. 따라서 독일에서도 법적 책임을 보다 명확히 하기 위해 자율주행시스템이 얼마만큼 운전자의 의지와 무관하게 작동하고 있는지, 운전자가 어떤 조치를 취하고 있는지, 그리고 운전자에게 어떠한 주의의무가 있는지 등의 판단기준을 통해 주체별 책임을 배분해야 한다는 논의가 있다. Unlike the United States, actively promoting legislations concerning autonomous cars, Germany is undergoing legal discussions with a more cautious view. The discussions include the range of issues under the current law when autonomous cars are commercialized and the direction of the discussions regarding applicable solutions of the issues. Such legal discussions are as the followings. First, since the majority of the legislations including Article 3, Section 1 of the `Highway Code (StVO)` in which stipulates that “A driver must drive the vehicle at a controllable speed” assumes a `human driver`, autonomous driving is not permitted under the current law in Germany. Therefore, to let autonomous vehicles to drive around Germany, ongoing discussions are on the regulations that concerns the `driver` since those are the most essential and fundamental issues to be addressed. Second, like Korea, Germany also deems the driver take primary responsibility in accidents while driving. However, since the person does not actually drive the autonomous car, it can be argued that one cannot place legal responsibility on the person thereof. Instead, the driver has the legal basis to argue that the car manufacturer should hold legal responsibility for the accident under the Product Liability Law (ProdHaftG). However, since the Product Liability Law imposes the burden of proof on the injured party, the party thereof cannot claim for the damages to the manufacturer unless they can prove the defect of the product. Ultimately, these regulations can lead to very ambiguous distribution of responsibility among owners of autonomous cars, drivers, and the manufacturers. Therefore, to clarify legal responsibility, arguments are underway in Germany on the distribution of liabilities of subjects. They insist that the distribution should be judged by the following standards; the range of the ability of an autonomous system on how much it can function regardless of the willingness of the driver, whether the driver carried out any measures, and the duty of care of the driver, etc.
