  • Artificial intelligence, which is in the spotlight as the core driving force of the 4th industrial revolution, is expanding its scope to various industrial fields such as smart factories and autonomous driving with the development of high-performance hardware, big data, data processing technology, learning methods and algorithms. In the field of defense, as the security environment has changed due to decreasing defense budget, reducing military service resources, and universalizing unmanned combat systems, advanced countries are also conducting technical and policy research to incorporate artificial intelligence into their work by including recognition systems, decision support, simplification of the work processes, and efficient resource utilization. For this reason, the importance of technology-driven planning and investigation is also increasing to discover and research potential defense future technologies. In this study, based on the research data that was collected to derive future defense technologies, we analyzed the characteristic evaluation indicators for future technologies in the field of artificial intelligence and conducted empirical studies. The study results confirmed that in the future technologies of the defense AI field, the applicability of the weapon system and the economic ripple effect will show a significant relationship with the prospect.

  • The experiment attempts to find out the effect of the mixture of the antimicrobial agent and insecticide on metallic material including Silver(99.9%), Copper(99.9%), Lead(99.9%) and Iron(99.5%) by Oddy test. The mixtures of the antimicrobial agent and insecticide were prepared in 60ml; with the standard concentration of 17.5% in B77 Essential oil mixture, one for mixture of concentration of ${\pm}1{\sim}2%$ and insect repellent material; the other for mixture of low concentration and antimicrobial agent(BS-2 and BS-3) material. After Oddy test, we investigated the variation in the surface of the samples by visual inspection, weighing, color measurement and SEM-EDS analysis. The result showed that Lead had the biggest change in the surface, and Copper had the biggest change in the color. In addition, changes in the samples before and after the experiment were found to be greatest at concentration of 19% of Essential oil mixture of the antimicrobial agent and insecticide. Also, B78 Essential oil mixture produce change in samples. It means when the concentration of oil mixture rises, the variation of the samples gets bigger. And, the low concentration of mixture including B77 Essential oil mixture and B78 Essential oil mixture also produce big change in the samples. However, the low concentration of B77 Essential oil mixture that do not contain B78 Essential oil mixture was able to confirm that the change of the surface is not large.

  • This is the result of the study on the temporary fortifier using sublimation type Consolidate is Cyclododecane to prepare plan for reinforcement of the surface part that can be damaged during the dismantling of stone cultural heritages. To supplement the disadvantages of the existing reinforcement methods using intumescent urethane foam, Cyclododecane was diluted in solvent to reinforce the surface and inside desquamation, and after dismantling the framework, it sublimated by imposing heat of about $60^{\circ}C$. Such method can guarantee the strength needed for reinforcement of the damaged surface with outstanding reversibility of Cyclododecane being entirely sublimated. But, it shows big difference of effect according to the solvent, so it shall be diluted in petroleum ether or heated in a double boiler. Therefore, considering the working conditions at the site, it seems the most appropriate to use petroleum ether double boiler heating method for injection and filling of the desquamation part and temporary reinforcement processing with Cyclododecane diluted in petroleum ether for surface spraying.

  • This study analyzed domestic media articles from 1920 to 2017 using R 3.4, a big data analysis tool. In addition, it examines the sexual minority discourse reproduced through the media for about 100 years, focused on the role of the film as an art of struggling with the projective aversion to sexual minorities. sexual minorities in movies are not abominable. They are people we already know in our daily lives, and they are just different in sexual orientation. In general, sexual minorities are less likely to encounter in everyday life, so they are experienced and perceived through what the media present. It is noteworthy that the representation of sexual minorities in the media is formed as a major agenda of our society by publicizing the problems underlying society on the surface. It causes social issues to be raised by revealing and highlighting the problems that are regarded as alienated and avoided from the mainstream's gaze. The content provided by the media enables a three-dimensional experience of subjects who have not experienced it by themselves, and has a decisive influence in correctly recognizing and judging society. Media content suggests that it can be a powerful weapon of recognition struggle that can naturally fight against social hatred without using methods such as demonstrations or protests.

  • The following is the study result of herbal tea roasted at different temperatures between $80{\sim}140^{\circ}C$. Depending on treatment temperature the water content decreased, some carbonization occurred and crude ash content relatively increased. Also crude protein and crude fat changed little. Benzopyrene content (0.17~0.35ppb) showed a tendency to increase with higher treating temperature. From this result, the $B({\alpha})P$ content differed depending on the treatment temperature and raw materials. In case of roasting, the actual inside temperature is around $200^{\circ}C$ but since the surface temperature of the roaster reaches around $2,000^{\circ}C$ some portion of $B({\alpha})P$ content was presumed to be produced from the area that came in contact with this surface. Solid elution rate of herbal tea showed 0.18~0.35%(w/w) and the rate of solid elution decreased with higher roasting temperature. There was no big change in $80{\sim}110^{\circ}C$ treatment section but the solid elution decreased rapidly in $110{\sim}140^{\circ}C$ section. The reason for decreasing solid elution rate at higher treatment temperature is because the compact inner tissue makes elution difficult.

  • The acupuncture and moxibustion documentary characteristics of "Chimgujasaenggyeong" can be summarized into 6 parts such as the follwing 1. "Chimgujasaenggyeong" was written at about 1180-1195 during the Southern Song period. It contains 7 volumes in all. The acupuncture points and their variations in volume 1 were all directly recorded from Wang-yuil(王維一)'s "Dong-insuhyeolchimgudogyeong(銅人腧穴鍼灸圖經)" and 11 points were added from volumes 99 and 100 of "Taepyeongseonghyebang(太平聖惠方)", bringing the total to 365 points, which was different from the 360 that the people knew. Volume 2 is the actual collection of theses on acupuncture and moxibustion by Wangjipjung(王執中) and shows his unique views on the basic problems of acupuncture and moxibustion such as selection of points[取穴], application of moxas[施灸], aftercare of moxibustion[灸後護理] and acupuncture and moxibustion contraindications[鍼灸禁忌]. Volumes 3${\sim}$7 mostly divide the indications(主治) from "Dong-insuhyeolchimgudogyeong", "Taepyeongseonghyebang", "Cheon-geumyobang(千金要方)" by disease into chapters. 2. Of the remaining editions the 'Cheonryeok Guanggeunseodang Inbon(天曆 廣勤書堂 印本)' of the Won dynasty is the first, and the Jeongtong(正統) new edition is a reprint based on the Cheonryeok(天曆) edition, and the Jeongtong edition reprinted in the 9th year of Guanmun(寬文) of Japan has many missing and wrong characters compared to the original copy. 3. The big letters[大字] under the line in the current editions are all postscripts[按語] of Wangjipjung and the 5 verses quoted from other books that do not have their origin listed and have the qualities of rules for treatment in the first chapter of volume 3 'Heoson(虛損)' were put together by Wang. 4. In the annotations in small print of the current edition of "Jasaenggyeong" there are Wisegeol(衛世傑)'s added annotations in addition to Wangjipjung's original ones. 5. Some of the many medical books quoted by the "Jasaenggyeong" that are from before the Song dynasty have been lost completely and only can be seen here in this important text. 6. The quotations said to be from 'Myeongdanggyeong(明堂經)'(or 'Myeongdang(明堂)', 'Myeong(明)') in "Jasaenggyeong" are directly from volume 77 'Chimgyeong(鍼經)' and volume 100 'Myeongdang' of "Taepyeongseonghyebang" and not another book. The quotes from 'Myeongdang' in accupuncture and moxibustion books after the Song dynasty were directly or indirectly copied from "Jasaenggyeong".

  • Korean traditional markets have been struggling of late as big-sized superstores and SSM(Super Supermarkets) are thriving in the market. They have therefore upgraded their facilities and undertaken management modernization actively to overcome the threat to traditional markets and ensure their competitiveness; however, the effect does not appear to be verifiable. The purpose of this study is to analyze the impact of the organizational characteristics of the traditional market merchant association on social capital and organizational performance. In other words, this paper investigates a merchant association's organizational characteristics in terms of the modernization of business activities of the traditional markets and the influence on their social capital and organizational performance. This study analyzes the traditional market by evaluating the impact of these factors. This study consists of four hypotheses: The first hypothesis relates to the causal relationship between the characteristics of a merchant association and social capital. The second and third hypotheses, respectively, relate to the causal relationships between the social capital of a merchant association and the merchant's satisfaction and that between the social capital of a merchant association and organizational commitment. The last hypothesis relates to the relationship between the organizational commitment of a merchant association and the merchant's satisfaction. This study conducts a reliability and validity analysis of the above factors and analyzes the causal relationships between them by using the PLS(Partial Least Squares) path model as one of the structural equation models. The results of the empirical analysis are summarized as follows: First, the organizational characteristics of the traditional market merchant association have a significant influence on social capital. However, only two sub-hypotheses are not significant; these insignificant hypotheses relate to the relationship between a merchant's entrepreneurship and structural capital and that between a merchant's entrepreneurship and cognitive capital. Second, the social capital of a merchant association influences organizational commitment significantly. Third, the relationship between the social capital of a merchant association and the merchant's satisfaction is mostly significant. However, one of the sub-hypotheses, that is, the relationship between relational capital and a merchant's satisfaction is not exceptionally significant. Lastly, the organizational commitment of a merchant association affect the merchant's satisfaction significantly. Through our extensive study, this paper found that a merchant association's organizational characteristics of the traditional market significantly affect social capital, organizational commitment, and satisfaction through the mediation of social capital. Therefore, in order to activate the key traditional market, an understanding of organizational characteristics and social capital is primarily required. Systematic management and investment pertaining to these two factors will be the first consideration for revitalizing traditional markets.

  • This study was performed from March to June 1994 in ANsung Medical Center. We investigated serum components of 78 diabetics in the center, in addition to the nutrient intake status and anthrophometric status of 60 diabetics among them. We separated the latter into 2 groups(ⅰ) less tan 5 years of diabetic duration and ⅱ) more than 6 years of diabetic duration) and analyzed the clinical characteristics of each group. The results are as follows : \circled1 The average ages of male and female subjects were 57.1 and 58.9 years, respectively. The average diabetic duration of male subjects was 4.8 years and that of female subjects was 5.9 . The major occupational field of both male and female subjects was agriculture(33.3%, 36.1%). 50% of male and 75% of female subject's monthly incomes were less than 600, 000 won and 75% of male and 94.4% of female subjects had weekly food expense less than 40, 000 won. The nutrient intake status of the subjects was lower than RDA on the whole. There was no big differences between 2 the male groups of different diabetic duration , but calorie, protein , fat carbohydrate, phosphorus, iron and Vit B$_1$intakes of the above 6 year female group were appearently higher than those of the under 5 year female group (p<0.05). There were different intake tendencies between male and female subjects . For females. the longer the diabetic duration, the less intakes of calorie, protein , fat carbohydrate, phosphorus, iron Vit B$_1$, Vit B$_2$, and niacin were observed. Furthermore, the longer the diabetic duration in females , the more intakes of energy and nutrients, except Vit C were observed. Fasting blood glucose levels were 155mg/dl and 164mg/dl and Postprandial glucose levels were 242mg/dl and 247mg/dl for males and females respectively. Hb of both males and females , and Ht of males met the lower limit of normal status, The serum TG level was higher than normal , so that they seemed to suffer from hyperlipidemia ; their high HbAIC status indicated that the management of diabetes mellitus was poor. The total protein level of female subject was higher when compared with that of males(p<0.05). All subjects blood pressure were higher than normal , and the longer the diabetic duration, the higher was the blood pressure. The serum HDL-cholesterol levels of the above 6 year group male subjects were lower(p<0.05) than those of the under 5 year male group subjects, and the former group's systolic and diastolic blood pressures were higher than those of the latter(p<0.05). Levels of serum total protein, albumin and TG of the above 6 year female group were lower than those of the under 5 year female group(p<0.05). As the diabetic duration was extended, HDL-cholesterol and LDL-cholesterol levels showed a tendency to increase, while Hb, Ht, total protein, albumin, and A/G, which represent the nutrients state of iron and protein, were inclined to decrease. This result showed that serum lipid components went bad. To summarize the results, the longer the diabetic duration, the worse were the male subjects nutrient intake status, but those of the female subjects were good. With respect to serum components and serum lipid subjects Fe, protein, nutrition status and serum lipid component got worse as the diabetic duration was extended , implying the possibility of diabetes mellitus complication grows.

  • The purpose of this study was to compare the eating habit, food intake frequency and preferred food and taste of juvenile delinquents (100 numbers) and male high school students (100 numbers), using questionnaires from August to October 2004. 1) It was shown that the juvenile delinquents took more unbalanced diet (p<0.05), smoking (p<0.001) and drinking (p<0.001) than general students, while general students had more eating between meals (p<0.01). 2) The intake of food was a significant difference in white rices (p<0.01), bibimbab (p<0.001), kimbab (p<0.001), fried rice (p<0.001), ramen (p<0.001), jajangmyun (p<0.001), jambong (p<0.001), hamburger (p<0.001), pizza (p<0.001) and breads (p<0.05). The juvenile delinquents took more major food than that of general students in all the items except for white rice. It was observed, then, that the juvenile delinquents showed more intake of such subsidiary foods as bulgoki (p<0.001), roasted thin pork chops (p<0.001), grilled pork belly (p<0.001), pork cutlet (p<0.01), sweet and sour pork (p<0.001), chicken with ginseng (p<0.001), fried chicken (p<0.001), kimchi pot stew (p<0.01) and zucchini (p<0.05) than general students, with general students taking more kimchi (p<0.01) and fried or boiled soybean curd (p<0.01). The intake of dessert was a significant difference in yogurt (p<0.01), orange juice (p<0.001), cola (p<0.001), soft drinks (p<0.001), ion drinks (p<0.001), coffee (p<0.001), apple (p<0.01), banana (p<0.001), orange (p<0.001), cake (p<0.001), hot dog (p<0.001), ddokbokgi (p<0.01), mandu (p<0.001), fried fish paste (p<0.05), steamed korean sausage (p<0.001), fried foods (p<0.05), hem & sausage (p<0.001), cheese (p<0.001), ice-cream (p<0.001), candy (p<0.01), chocolate (p<0.001), mayonnaise (p<0.05), jam (p<0.01) and butter & margarine (p<0.01). Then, the juvenile delinquents were shown to entirely have more intake of all the desserts than those of general students. 3) Regarding preference of foods, it was shown that the juvenile delinquents preferred cereals (p<0.05), grilled pork belly (p<0.001), chicken with ginseng (p<0.01), anchovies and small fish (p<0.05), chicken with ginseng (p<0.05), seasoned spinach (p<0.001), seasoned zucchini (p<0.001), milk (p<0.05), coffee (p<0.001) and butter & margarine (p<0.05) while general students did egg (p<0.01), soybean sprout soup (p<0.001), boiled or fried potato (p<0.05), seasoned soybean sprout (p<0.05), boiled or fried soybean curd (p<0.01), fried foods (p<0.01) and snack (p<0.05). For their preference of tastes, hot taste (p<0.01) was higher in the juvenile delinquents. 4) Under general environments there was a change of the difference in their behaviour of pork cutlet (p<0.01) intake in accordance with other family and of milk (p<0.001) and butter & margarine (p<0.05) preference in accordance with growth in a big city between the two groups.

  • This study will show the determinants of research productivity by fields in science and engineering. However, we present the differences between fields by personal attributes, research resources, and research productivities. The data includes 1,383 researchers who participated in the BK21 PLUS program during 2010-2012. The fields are physics, chemistry, biology, mechanics, electricity and electronics and chemical engineering. As for research productivity, 3 indices are used such as the number of papers publicized, patents and combination of papers and patents. As for explanation factors, two kinds of variables are used. The personal factors include sex, age, academic rank, location of affiliation, and country of PhD acquisition, and the resource factors are the number of graduate students, 3 types of research funds such as government fund, industrial fund and overseas fund. This study is unique in several aspects; Dealing with 3 productivity indices, and using massive official data, 6 different fields, and determinants of research productivity. The results are as follows; 1) there is a big difference in determinants by fields. 2) No variables affect the research productivity of all the fields at the same time. 3) In science, the number of determinants are quite low than engineering. 4) The ratio between papers and patents are different by fields. 5) The correlations between paper and patent by fields are different; no relationship in the field of physics and chemistry and positive relationship in the other 4 fields.
