과정철학의 관점에서 고찰한 아인슈타인의 상대성이론

임진아 한국화이트헤드학회 2012 화이트헤드 연구 Vol.0 No.23

It examined how you could interpret a principle of relativity of Einstein in a concept of the process philosophy of white head. We can get three kinds of conclusions. It is the point that recognized the magnitude of the 'relation' with both for an essential figure naturally first. When it is an element of the true ultimate, Whitehead insists on 'event' and 'actual entity' that it cannot think about itself when it right leaves the meaning significance. Einstein was limited in a physical field, his special theory of relativity tied up the time-space, energy-mass. It went step further and proved that mass (energy) had influence that it could not separate on the time-space in the general theory of relativity. In other words, it can tell you that it is to have formed a structure of the universe that seems to be today through space, energy, an end between the mass of relationships at time. The second, thing about the different point that a relativity concept of Whitehead has with Einstein. It was certain that Einstein recognized the magnitude of relations, but it completely wiped out a thought for 'absoluteness' and was not able to leave. It gave absoluteness to velocity of 'light' in the special theory of relativity and 'mass' in the general theory of relativity. It expanded an extended claim to the area of so-called philosophy (ontology) to speak by insisting on the theory of relativity to have a meaning because white head got away from the limitation called the scientific field called the physics in the magnitude of relations, and all things had relations each other. The third, two people have a difference of the point of view for the substance of nature. Though Einstein recognized the magnitude of relations and completely changed a way of thinking of the universe for the structure of the universe, the substance of nature was not able to get away from what way of thinking that had a material as ever. Whitehead showed a concept innovative (the whole area) to an entity concept in a lifetime. It is 'event' and 'actual entity' immediately. He did a claim that substance was inherent in a different subject. This is the claim that cannot be possibly understood in the concept called continuing substance having a material. 1905년과 1915년에 발표된 아인슈타인의 특수 상대성이론과 일반 상대성이론이 가져온 변혁은 인류가 생각해왔던 시간과 공간에 대해 가지고 있던 사고방식을 완전히 혁신하게 했고, 태초와 우주에 대한 인류의 관점을 완전히 재정립하도록 만들었다. 뉴턴역학에서는 불변하는 기준으로 시간과 공간을 상정해 놓고, 시간과 공간을 무대로 삼아 변화하는 물체에 대한 논의를 하였다면, 아인슈타인은 시간과 공간은 절대적인 기준이 아닌 관찰자에 의해 변화하는 상대적인 개념이라고 말한다. 또한 화이트헤드 역시이 글에서는 첫째, 아인슈타인의 상대성이론에서 말하는 상대성이란 과연 무엇인가를 상세히 살펴본 결과, 아인슈타인의 상대성은 엄밀하게 말하면 ‘상대성’이라 말할 수 없다는 것을 알 수 있다. 그는 ‘절대’개념을 결코 포기하지 않았음을 알 수 있다. 그의 이론에서는 ‘빛’과 ‘질량’이 새로운 절대를 위한 초석으로 등장한다. 둘 째, 아인슈타인의 상대성이론과 화이트헤드의 상대성원리의 관계에 대한 것이다. 화이트헤드의 상대성원리는 존재론적인 영역으로 확장된 것이다. 그러므로 화이트헤드는 아인슈타인의 이론을 충분히 포괄하고 있으며, 나아가 우주의 모든 사물이 존재의 근거 역시 관계성 속에 놓여있음을 역설한다.

배암차즈기 메탄올 추출물의 항산화 활성 및 아질산염 소거능

임진아,윤보원,백승화 한국약용작물학회 2007 한국약용작물학회지 Vol.15 No.3

본 연구는 배암차즈기 메탄을 추출물의 생리활성 및 기능성을 검토하기 위해서 항산화효과 및 아질산염 소거능을 측정하였다. 그 결과, 배암차즈기 메탄을 추출물의 전자공여능(RC50)은 51.10 μg/ml로 나타났고 SOD 유사활성은 추출물(0.92mg/ml)을 첨가하였을때 62.11%로 가장 높게 관찰되었으며, linoleic acid에 대한 항산화력은 추출물 (0.2mg/ml)을 첨가하여 지질과산화물을 측정한 결과 배양시간 1, 2, 4일 경과후 각각 72.86%, 77.18%, 78.32% 감소율을 보임으로써 효과적인 항산화 효과를 나타내었다. 총 페놀함량은 gallic acid equivalents (GAE)로 측정되었고, 202.35± 1.26 GAE μ extract으로 조사되었다. 아질산염 소거능은 복합 생약추출물(0.2mg/ml)을 첨가하였을 때 pH 1.2조건에서 44.29%로 가장 높게 나타났으며 pH가 증가할수록 감소하였다. 이상의 결과로 배암차즈기 메탄을 추출물은 우수한 항산화 효과와 아질산염 소거능을 나타냄으로써 기능성 식품 소재 및 식품 첨가물로써 사용가능 하리라 사료된다. Efficacy of antioxidative activity and nitrite scavenging ability of methanol extract from Salvia plebeia was investigated. Electron-donating ability of extract at RC50 was 51.10 μg/ml. After addition of 0.92 mg/ml extract, autooxidation of pyrogallol decreased to 62.11% by superoxide dismutase-like activity. In antioxidative activity of extract against linoleic acid during incubation times of 1,2, and 4 days at 40˚, lipid peroxidation values significantly decreased by 72.86%, 77.18%, and 78.32% with addition of 0.2 mg/ml, respectively. Total phenolic content was determined as gallic acid equivalents (GAE) and values revealed as 202.35± 1.26 GAE μg/ml of extract. Nitrite scavenging ability showed the most remark-able effect at pH 1.2, exhibited to 44.29% by addition of 0.2 mg/ml. These results suggest that methanol extract from Salvia plebeia can be used as bioactive and functional materials.

임진아,WANGXIA 한국벤처창업학회 2024 벤처창업연구 Vol.19 No.2

This study examines the impact of university graduate Startup rates on economic growth in the regions where universities are located, using panel data from 35 universities in 17 regions in Korea and 21 universities in 13 cities in China over a six-year period from 2016 to 2021. In Korea, a total of 35 universities were selected as part of the Ministry of Education's "University-initiated Startup" policy, including Startup-oriented universities, leading universities in Startup education innovation, Startup education bases, and excellent universities in Startup education, while in China, 21 universities were selected as part of the pilot bases established as part of the "Mass Entrepreneurship, Mass Innovation" policy. To analyze the economic impact of the universities on the regions where they are located, we aimed to conduct an empirical analysis of the economic impact using economic indicators of the economic growth rate of the regions where they are located. The results of the empirical analysis show that the Startup rate of university graduates in Korea and China both have a positive impact on the regional economic growth rate, but the Startup rate of local university graduates in Korea has a greater impact on the regional economy than in China. Based on the findings that the number of entrepreneurs produced by universities has a positive impact on the economic growth of their regions, this study draws implications for the role of universities and regions in revitalizing local economies and the establishment of systems to resolve the imbalance between metropolitan and non-metropolitan areas.

Acoustic Cues of Korean Stops: With Respect to Regional Dialect, Generation, and Gender

임진아 현대문법학회 2024 현대문법연구 Vol.122 No.-

The purpose of this study is to investigate the ranking of Voice Onset Time (VOT) and Fundamental Frequency (F0) according to regional, generational, and gender differences. Specifically, we examined whether VOT and F0 are uniformly applicable across regional dialects, generations, and genders in dis- tinguishing between Korean lenis and aspirated stops. A total of 120 participants took part in this study, with five participants from each regional dialect, gender, and age group. The results of this study indicate: firstly, across all regions, F0 serves as the primary cue for distinguishing between lenis and aspirated stops. Secondly, the phenomenon of VOT merging, where the VOT of lenis and fortis stops becomes similar, is more frequent among younger generations and female speakers. Thirdly, speakers aged 50-60 still rely on VOT to distinguish between lenis and aspirated stops. Fourthly, Gyeongnam dialect speakers, notably, particularly those in the 10-20 age group, exhibit a pronounced VOT merging phenomenon, relying solely on F0 to distinguish between lenis and aspirated stops, whereas speakers aged 30-40 and older continue to distinguish based on VOT. These findings suggest that the significance of this study in demonstrating that the phenomenon of VOT merging in Korean lenis and aspirated stops does not occur uniformly across all regional dialects, generations, and genders.

This study aimed to investigate the association between the microbial characteristics of farrowing in pig farms and the growth performance of piglets. To compare the microbial characteristics of farrowing houses with different piglet growth rates, samples were collected from the floor, walls, and water troughs of conventional (Group A) and animal welfare-oriented (Group B) farrowing houses. Microbial samples were collected weekly, starting from immediately after piglet birth until the 21st day, spanning three weeks. The results revealed that microbial abundance and evenness were higher in the Group A farrowing houses compared to Group B. Microbial composition analysis indicated that pathogenic microbes such as the Christensenellaceae R-7 group, Staphylococcus, Actinobacillus, and Escherichia-Shigella were more prevalent in the Group A farrowing houses than in Group B. Predicted microbial metabolic functions showed increased metabolism related to infections associated with Mycobacterium, and the pathogenic microbes Staphylococcus aureus and Salmonella, and degradation metabolism of chlorocyclohexane, chlorobenzenes, and dioxins in Group A. In contrast, Group B exhibited a higher metabolism related to protein synthesis, vitamin, amino acid biosynthesis, and methane metabolism. The piglets in Group B showed significantly higher weight gain by the 21st day. These results suggest that the environmental microbes in pig farm farrowing houses may influence piglet growth performance. Further research is needed to explore the interactions between the farrowing house environmental microbes and piglet fecal microbes to better understand their impact on the formation of piglet gut microbiota.

만 5세 유아의 부모참여에 영향을 미치는 생태학적 관련변인 탐색

임진아,오재연 한국열린유아교육학회 2008 열린유아교육연구 Vol.13 No.4

The purpose of this study is to examine the actual participation pattern of parents whose children are ready to join elementary school in children's education from the aspect of ecological and other externalities. In addition, this study will determine the external causes and the ecological system, which has a significant influence on the actual participation behaviors and activities of both mothers and fathers. This study is based on revised and supplemented survey of questionnaires composed of ecological questions as well as FIQs. It was conducted on 156 set of parents, both mothers and fathers, with children of 5 years of age attending either kindergarten or nursery homes in Kwangju and Yeosu province. The analytical tool applied in this survey includes frequency, average, percentiles, independent sample distribution of t-testing, Hierarchical Recurrence Analysis and Multiple Regression Analysis using the stepwise methodology. External elements having influence on the level of participation in fathers included, in order of significance, employment/unemployment status (41%), level of devotion in education, level of employment satisfaction, and the level of satisfaction in the kindergarten and nursery homes. Meanwhile, the external factors which influence the level of participation of mothers differed from those of fathers. Mothers valued their level of satisfaction in the kindergarten and nursery homes (37%) as the most important fact in deciding on their actual participation, which was then followed by factors like level of devotion in education, the education level institutional classifications and employment/ unemployment status. Therefore, when devising a scheme to promote active parental participation, we must first understand the ecological reasons influencing the sub-categories of parental participation of both mother and father, and establish strategic programs which can have strong influence on elements like the level of devotion in education, which are comparatively easier to control and change, compared to other ecological elements, which are very difficult, or even impossible to influence. 본 연구는 초등학교 입학을 앞둔 유아기 자녀 부모의 생태학적 관련변인들과 다양한 측면의 부모참여 실제가 어떠한지 파악하고, 부모 참여 실제의 양상을 생태학적 접근방법으로 규명하여 아버지와 어머니의 참여활동에 영향을 미치는 주요변인 및 생태학적 체계를 밝혀내는 것을 목적으로 한다. 만 5세 유아의 아버지와 어머니 156쌍을 대상으로 하여 자료를 수집하였으며 빈도, 평균, 백분율, 독립표본 t검증, 위계적 회귀분석과 stepwise방식에 의한 중다 회귀분석을 통해 분석하였다. 그 결과, 아버지의 참여활동에 영향을 주는 변인으로는 취업상태, 교육열, 직장만족도, 유치원만족도였으며, 어머니의 참여활동에 영향을 주는 변인으로는 유치원만족도, 교육열, 부모의 학력, 기관유형, 취업상태로 나타났다. 따라서 부모참여를 강화시키기 위한 전략을 세우고자 할 때 각각의 부모참여 하위영역에 영향을 미치는 생태학적 변인들을 파악하고, 다른 생태학적 변인들에 비해 조정 가능한 ‘교육열’ 변인을 변화시키기 위한 프로그램 전략을 계획할 필요가 있다.
