안수미 세종대학교 대학원 2008 국내석사

Perfluorosulfonic acid membrane (NafionⓇ), which is most widely used for polymer electrolyte membranes fuel cell (PEMFC), discovers low thermal stability and low proton conductivity at high temperature. The acid-base polymer membranes, molecularly blended each other due to the formation of ionic interaction between the acid polymer and base polymer, was known to be achieved to overcome the disadvantage. In this study, we prepared acid-base polymer blend using sulfated dextran, as an acid polymer and polyethyleneimine or poly(vinyl pyrrolidone), as a base polymer. The membranes were prepared by solution casting method. The prepared membranes were characterized by Fourier transform infrared to verify the formation of the ionic interaction, thermogravimetric analysis and differential scanning calorimeter to assess the thermal stability. Surface morphology of membrane was observed using scanning electron microscopy. Proton conductivity of the membrane increased the more content of acid polymer at high temperature.

The efficacy of pine nut, which is a Korean traditional food, is widely acknowledged not only in Korea but also in other countries. As a result, the use of pine nuts has been widened, and foods utilizing various nuts have been developed. Studies on the supercritical fluid extraction process have been actively carried out as an extraction technique to replace the problem of nutrient destruction and impurity residue in high temperature squeeze extraction, which is a method of extracting existing pine oil. Supercritical fluid extraction is a technique of using a fluid under a double-sided condition with a density (solvent effect) similar to that of a liquid phase, having a transmission property such as a diffusion coefficient and a viscosity similar to those of a gas phase at a pressure and a temperature higher than a critical point, Food industry, medicine, environment industry, and the like. Pine nuts, which are waste resources after the extraction of nuts, are rarely studied. The purpose of this study was to compare the lipid oxidation stability, storage temperature and color change of supernatant with supercritical fluid extraction method and to investigate antioxidant effect and antioxidant activity of nuts. Lipid oxidation stability of pine oil showed that supercritical fluid pine nut oil was stable at room temperature rather than high temperature compressed pine oil. However, high temperature storage of supercritical. As a result of measuring the color of pine nut oil, the difference in color difference between the high temperature pressed noodle oil and the supercritical fluid noodle oil was small in the room temperature storage, and the high temperature pressed noodle oil showed a large chromaticity change compared to the supercritical fluid noodle oil.

The purpose of this study was to examine the pathways of mothers' inappropriate smart device usage habits, the children's immersion tendency and self-regulation ability on children's cognitive ability. The subjects of the study were 308 four- and five-year-olds and their mothers who are attending in 11 public and private daycare centers and 12 private and public kindergartens located in Seoul, Gyeonggi-do, Incheon, Gangwon-do, Daejeon, Busan, and Mokpo. The mother's inappropriate smart device usage habit was assessed by the questionnaire modified by Lee(2014). The smart phone immersion tendency of the children's was assessed by the questionnaire modified by Lee(2017). The children's self-regulation was assessed by the questionnaire developed by Lee and Yang(2003). Children's cognitive ability was assessed by the ‘4-6 year old child development level test’ developed by the National Institute of Education and Evaluation(1996). A path analysis was conducted to examine the effects of mothers' inappropriate smart device usage habits on children’s cognitive ability and the mediating pathways of the child’s immersion tendency of smart devices and self-regulation. The control variables were child’s age, gender, private education and mother’s final education. To verify the significance of the mediating effect, the Bias Corrected Bootstrapping method was performed. The summary of the results of this study is as follows. First, it was found that mother's inappropriate smart device usage habits increased children's tendency to immerse themselves in smart devices. Second, the higher tendency of smart device immersion was related to lower self-regulation. Third, self-regulation had a positive effect on children's cognitive ability. In conclusion, mother's inappropriate smart device usage habits negatively affected the children's self-regulation and this association was partially mediated by the children's smart device immersion tendency. These findings show the mechanisms of how mother’s inapropriate smart device usage habits negatively affect on children's smart device immersion and self-regulation which in turn have negative effect on children's cognitive ability. 본 연구에서는 어머니의 부적절한 스마트기기 이용습관, 유아의 스마트기기 몰입 경향성 및 유아의 자기조절력이 유아의 인지능력에 미치는 경로에 대한 메커니즘을 살펴보고자 하였다. 연구대상은 서울시, 경기도, 인천시, 강원도, 대전시, 부산시, 목포시에 위치한 국공립 및 민간 어린이집 11곳과 사립 유치원 및 국공립 유치원 12곳에 재원 중인 만 4, 5세(4세 111명, 5세 197명) 유아와 해당 유아의 어머니 308쌍을 대상으로 하였다. 어머니의 부적절한 스마트기기 이용습관은 이윤미(2014)의 도구에서 스마트폰을 스마트기기로 수정하여 사용하였으며, 유아의 스마트기기 몰입경향성은 한국정보화진흥원에서 개발한 ‘유·아동 인터넷 중독 진단 척도(2011)’를 이명숙(2017)이 스마트기기에 맞게 수정한 도구를 사용하였다. 유아의 자기조절력은 이정란, 양옥승(2003)이 부모용으로 개발한 유아의 자기조절력 검사 도구를 사용하였으며, 유아의 인지능력은 국립교육평가원(1996)에서 부모용으로 개발한 ‘만 4∼6세 유아 발달 수준 검사’ 중 학습에 대한 관심 및 창의성과 수·과학 하위영역만을 사용하여 측정하였다. 수집된 자료는 차이검증 결과 통제변인을 성별, 연령, 외부 교육프로그램 이용시간, 어머니의 최종학력으로 최종 선정하였다. 어머니의 부적절한 스마트기기 이용습관이 유아의 스마트기기 몰입경향성, 유아의 자기조절력을 거쳐 인지능력에 미치는 영향을 살펴보기 위해 경로분석(path analysis)을 실시하였으며, 유아의 스마트기기 몰입경향성의 매개효과 유의성 검증을 위해서 부트스트래핑(Bias Corrected Bootstrapping)방법을 실시하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 어머니의 부적절한 스마트기기 이용습관이 유아의 자기조절력에 미치는 영향에서 유아의 스마트기기 몰입경향성의 매개효과는 유의한 것으로 나타났다. 즉, 어머니의 부적절한 스마트기기 이용습관은 유아의 스마트기기 몰입경향성을 높이고, 유아의 스마트기기 몰입경향성이 높을수록 유아의 자기조절력은 낮게 나타났다. 둘째, 어머니의 부적절한 스마트기기 이용습관 및 유아의 스마트기기 몰입경향성은 유아의 인지능력에 유의한 영향이 나타나지 않았으나, 유아의 자기조절력은 유아의 인지능력에 유의한 정적 영향이 나타났다. 결론적으로, 어머니의 부적절한 스마트기기기 사용습관이 유아의 스마트기기 몰입경향성을 매개로 유아의 자기조절력을 거쳐 유아의 인지능력에 영향을 미치는 메커니즘을 제시하였다.

This study aims to use of medicinal and edible ramie leaf(Boehmeria nivea L.) as a material for functional foods. The fresh ramie leaf was dried with hot-air, cold-air and freeze drying methods. They were powdered and analyzed their physicochemical compositions including proximate composition, vitamin C, amino acid, fatty acid, mineral, and color. The antioxidant activities of the powered ramie leaf were also analyzed by DPPH radical scavenging activity, ABTS radical scavenging activity, total polyphenol. In addition, quality characterization of pork patties added with varying amounts of freeze-dried ramie leaf powder were also investigated in this research. Crude protein, crude fat, crude ash contents were highest in freeze-dried ramie leaf powder, while moisture content was highest in cold-air dried ramie leaf powder. Vitamin C content was higher in freeze-dried ramie leaf powder. The total and essential amino acid were higher in freeze-dried ramie leaf powder and the major amino acids were glutamic acid, aspartic acid, and leucine. The ratio of essential amino acid was highest in cold-air dried ramie leaf powder. The major fatty acids in ramie leaf powder were linolenic acid, linoleic acid, palmitic acid, oleic acid, palmitic acid, and stearic acid. The contents of unsaturated fatty acids was higher than that of saturated fatty acids, and unsaturated fatty acid contents were higher in freeze-dried ramie leaf powder. In mineral contents, Ca was the highest followered by K, Mg, P and Na. Brightness(L*) and yellowness(b*) of chromaticity was the highest, while redness(a*) was lowest in the freeze-dried ramie leaf powder. The freeze-dried ramie leaf powder showed the highest DPPH radical scavenging activity, ABTS radical scavenging activity and total polyphenol content followed by hot-air dried powder and cold-air dried ramie leaf powder. The moisture contents of pork patties containing freeze-dried ramie leaf powder were lower than that of control patty, but there was no significant difference in moisture and pH values between the patties. With increasing amounts of freeze-dried ramie leaf powder in pork patties, chromaticity decreased in brightness(L*) and redness(a*), but increased in yellowness(b*) in the raw and cooked patties. In texture analysis, hardness, springiness, cohesiveness, and chewiness of the pork patties increased as more freeze-dried ramie leaf powder was added to the pork patties. Cooking loss had a tendency to decrease in pork patties containing ramie leaf powder compared with the control group. Thiobarbituric acid reactive substances (TBARS) values increased during storage in pork patties without freeze-dried ramie leaf powder, but those formulated with freeze-dried ramie leaf powder showed lower TBARS values than those in the control groups. Sensory panels determined that pork patties containing 0.5%(w/w) freeze-dried ramie leaf powder had higher scores for overall acceptability.

This paper compared two languages that have different way of thought and codes in different cultures. Through this comparison, it examined the meaning of translation, standard, and the difference of thought, involving translation. Chapter 2 investigated the concept and standard of translation in terms of theory. Translation is to express from one language to another and match the meaning. So, the first thing that we should do in translation is to be faithful to the original text, secondly, translation should be natural, and thirdly, it needs not to lose the characteristics and dignity of the original text. Chapter 3 divided the difference of thought in translation, appeared in some aspects such as history and culture, custom and culture, and language habit, and then explored the cause of thought's gap. First of all, in regard to types of thought, there are shape-centered thought and abstract thought. Chinese expresses the shape, which is seen in our sight, but Korean expresses abstractly by selecting out the common attribution of things and synthesize it. Secondly, there are curvilinear thought and straight linear thought. Generally, because in Chinese, predicates, which belong to the core of sentence, are ahead, it expresses the meaning in a straight way. However, in Korean, modifiers are ahead and predicates are behind of them in order, it leads curvilinear thought. Thirdly, there are objective thought and subjective thought. On the account that there is no change of form in Chinese, when we see the same word that has same form in other sentence, we interpret it subjectively in the process of understanding the word, suitable for the sentence. On the other hand, in Korean, on the account that the element of word is clearly revealed in the sentence by the postpositional particle, the difference of thought is existed as subjective thought and objective thought in terms of objective understanding. Fourth, there are formal logic and dialectical thought. Generally, the words in Korean are changed according to the role of sentence. In contrast to this, because Chinese is the isolated word, the form of word is remained without change in the sentence, and it can be thought and expressed dialectically according to the whole meaning of the sentence. In the part of grammar feature, Chapter 4 tried to explain the difference between Chinese and Korean through the word order of Chinese and the postpositional particle of Korean. Therefore, we need to keep in mind that the flow of sentence can be natural by using the appropriate postpositional particle and thereby the thought and emotion of original text are kept alive in translation. Chapter 5 revealed that even though the figurative object of these two races have similarities in the feature of expression way, it is represented differently according to their different way of life, thought way, the view for the beautiful, and so on. Accordingly, we need to put to practical use the figurative method for the vigorousness, clarity, simplicity, and easiness in accordance with our language habit, along with strenuous effort for the exact representation of custom's condition and expression way of other race. To sum up, different way of thought is likely to give birth to another language. Therefore, translators should be careful in the language difference, caused by the way of thought and they need to be faithful to the accurate understanding and translation of the original text.

Obesity is presently one of the main social health problems in many developed countries due to the development of major chronic disease, including cardiovascular disease, diabetes, and cancer. One of the obesity therapeutic approaches for preventing obesity is to retard the absorption of fatty acid through the inhibition of lipase in the digestive organs. In the present study, to develop functional food and anti-obesity drug through the inhibition of dietary lipid absorption, we investigated the inhibitory effects of extracts from Opuntia ficus-indica (L.) Mill on pancreatic lipase. Opuntia ficus-indica (L.) Mill is widely used as folk medicine for burned wound, edema and indigestion. Many studies on biological activities of Opuntia ficus-indica (L.) Mill have been reported, but inhibitory effects of this are not clarified not yet. Opuntia ficus-indica (L.) Mill was extracted with 80% methanol. Various concentrations (100ng/ml, 1ug/ml, 10ug/ml, 100ug/ml) of exract were added to 3T3-L1 preadipocytes and adipocytes induced differentiation with hormone mixture (insulin, dexamethasone and 3-isobutyl0methoxyxanthin) to estimate the effects on proliferation and differentiation. Methanol extract of Opuntia ficus-indica (L.) Mill inhibits proliferation compared with PBS treated control on 3T3-L1 preadipocytes in 100ng/ml, 1ug/ml, 10ug/ml, 100ug/ml. 3T3-L1 adipocytes treated with Opuntia ficus-indica (L.) Mill extracts accumulated 94.62%, 108.02%, 104.54%, 91.62% of intracellular lipid droplets by Oil Red staining. Five week-old ICR twenty-five mice were divided into 2 groups by dietary fat source, normal diet containing 7%(w/w) fat and high fat diet containing 40%(w/w) fat, and then high fat groups were subdivided into 4 treatment groups depending on Opuntia ficus-indica (L.) Mill high fat diet control(HFC), high fat diet containing 0.1% Opuntia ficus-indica (L.) Mill (HF1), high fat diet containing 0.5% Opuntia ficus-indica (L.) Mill (HF2) and high fat diet containing 1% Opuntia ficus-indica (L.) Mill (HF3). ICR mice fed for 3 weeks and the daily body weight of Opuntia ficus-indica (L.) Mill treatment groups(HF1 ; 0.36±0.04g, HF2 ; 0.34±0.07g, HF3 ; 0.34±0.04g) were significantly(p<0.05) lower than those of the control group(0.67±0.04g). Intake of Opuntia ficus-indica (L.) Mill decreased serum triglyceride. Especially Serum triglyceride of HF2(10.5±2.5mg/dl) and HF3(8.6±2mg/dl) groups is significantly(p<0.05) different from those of HFC(44.0±16.0mg/dl). Total cholesterol and HDL-cholesterol of HF groups is different from those of HFC. Serum GOT content of HF2 is significantly decreased compared with those of control group(p<0.05). The present study assessed the effects of Opuntia ficus-indica (L.) Mill on the activity of pancreatic lipase in vitro and on the degree of fat excretion in faces of mice by the oral administration of a high-fat diet for three weeks. Although methanol extract of Opuntia ficus-indica (L.) Mill is shown to have strong inhibitory effect against pancreatic lipase in vitro, fat excretion in faces of groups fed Opuntia ficus-indica (L.) Mill is lower than those of the HF group. The anti-obesity effects of Opuntia ficus-indica (L.) Mill in high fat diet-treated mice be partly due to the inhibition of intestinal absorption of dietary fat and adipogenesis by suppression on accumulating lipid droplet in 3T3-L1 adipocytes.

물체의 위치 검출은 산업 현장에서 부품가공, 부품제작, 자동검사에 있어서 nano-technology가 적응되면서 그 필요성이 더욱 부각되고 있다. 이에 본 연구에서는 궁극적으로 sub-micrometer 위치 분해능을 가지면서 실시간으로 위치 정보와 경사각 정보를 획득할 수 있는 광센서 제작 연구를 수행하였다. 레이저광을 물체에 경사지게 조사하고 반사된 광을 position sensitive detector(PSD)로 검출하여 물체의 상대위치를 산출하였으며, 또 다른 레이저광을 수직 방향으로 물체에 조사하여 반사된 광을 PSD로 검출하여 상대경사각을 산출하였다. 이 두 개의 정보를 이용하여 물체의 절대위치와 절대경사각을 산출하였다. Searching for the location of an object has became more important as nanotechnology has adjusted to the manufacturing and production of components and automatic inspection in the field of industry. In this study, we accomplished the research of an optical sensor that acquires the information of location and angle of inclination in real time with the disjointing function of the sub-micrometer. By irradiating the laser diagonally to the object, we yield the information of object’s location by detecting the reflected light by position sensitive detector(PSD). Furthermore, irradiating another laser vertically to the object will yield another angle of inclination through the reflected light. Through the two points of data, we yield the absolute location and angle of inclination of the objects.

아버지의 자녀양육에 대한 관심이 높아지고 아버지의 역할에 변화가 나타나고 있음에도 불구하고 아버지가 자녀양육에 보내는 시간은 크게 증가하지 않고 있는 것으로 나타나고 있다. 이에 본 연구는 자녀양육시간에 관한 다양한 관점과 아버지의 양육행동의 특성을 반영하여 자녀양육시간을 측정하고자 자녀양육시간을 자녀돌보기시간, 가사공유시간, 여가공유시간으로 구성하고, 아버지의 자녀양육시간의 경향과 아버지의 자녀양육참여에 영향을 미치는 요인을 실증적으로 분석하고자 하였다.연구의 주요 결과는 다음과 같다. 첫째, 아버지의 자녀양육시간은 아버지의 자녀양육시간을 주행동으로 행해진 자녀돌보기시간으로 측정할 경우 평일 17분, 일요일 32분으로 나타나지만, 동시행동으로 이루어진 자녀돌보기시간과 자녀와 가사노동을 함께 한 가사공유시간과 여가활동을 함께한 공유시간으로 확대하여 측정할 경우 평일 44분, 일요일 166분의 시간을 자녀양육에 사용하는 것으로 나타났다. 둘째, 아버지는 아버지의 노동시간이 적을수록, 막내자녀가 어릴수록, 배우자의 월평균소득이 높을수록, 아버지의 교육수준이 대학원이상일 때 자녀돌보기에 참여할 가능성이 높은 것으로 나타났다.아버지의 가사공유참여에 영향을 미치는 변수는 평일에는 노동시간인 것으로 나타났으며, 일요일에는 아버지의 노동시간, 아버지의 직업, 막내자녀 연령이 영향을 미치는 것으로 나타났다. 아버지의 여가공유참여는 평일에 아버지의 노동시간, 아버지의 직업, 자녀의 수, 막내자녀의 연령의 영향을 받는 것으로 나타났으며, 일요일에는 아버지의 노동시간과 막내자녀연령의 영향을 받는 것으로 나타났다. 셋째, 자녀의 취학여부에 따라 아버지의 자녀양육시간이 차이가 있는지를 살펴본 결과, 평일과 일요일 모두에서 미취학, 미취학과 취학, 취학의 순으로 자녀가 성장함에 따라 자녀돌보기시간이 크게 감소하는 것으로 나타났으며, 가사공유시간과 여가공유시간은 미취학과 취학자녀를 둔 아버지가 자녀가 모두 미취학이거나 모두 취학인 아버지에 비해 자녀와 함께 공유하는 시간이 더 많은 것으로 나타났다. 아버지의 자녀양육참여유형은 자녀가 모두 미취학인 아버지는 평일에는 돌보기형이 39.1%로 자녀돌보기에 집중적으로 시간을 사용하고 있으며, 미취학과 취학자녀가 있는 아버지는 자녀가 모두 미취학인 아버지에 비해 돌보기형이 적고 시간공유형의 비율이 많았다. 자녀가 모두 취학인 아버지는 53.3%가 자녀양육시간에 전혀 참여하지 않는 비참여형인 것으로 나타났으며 자녀가 성장할수록 직접적인 자녀돌보기에 참여하지 않고 자녀와의 공유시간에의 참여만 이루어지는 것으로 파악되었다. 일요일의 경우 자녀가 모두 미취학인 아버지의 대부분이 자녀양육에 참여하며, 미취학과 취학자녀가 있는 아버지 역시 평일에 비해 일요일에 병행형이 크게 증가하고 돌보기형이 감소하는 것으로 나타나 평일에 자녀돌보기에만 참여하던 아버지들이 일요일에 자녀와 시간을 공유하는 것으로 파악된다. 자녀가 모두 취학인 아버지는 일요일에 시간공유형이 58.0%로 과반수가 넘는 아버지가 이 유형에 속하는 것으로 나타났다.
