Purpose The radiopharmaceutical used in the nuclear medicine department is used only for the specific patient according to the prescription or instruction of the doctor without selling, so it is dispensed and it is distributed and used for the examination. Radiopharmaceuticals administered to patients should be managed appropriately as well as radiation safety management during dispensation. The purpose of this study is to investigate microbial contamination during dispensation of radiopharmaceuticals Materials and Methods This study distinguished between general workbench and clean workbench and performed three tests. First, microbial cultivation test of radiopharmaceutical prepared and dispensed in general workbenches and sterile workbenches were carried out five times, respectively. The second test was performed settle plate method three times before and after the use of the exhaust filter. Finally, Adenosine Triphosphate (ATP) measurement was performed in each workbench to measure bacterial counts. In addition, ATP measurement were carried out by designating locations and items that may be contaminated during dispensation. Results In the microbial culture test, no microorganisms were detected in both samples. In the settle plate method, it was detected without using of the exhaust filter in a general workbench once. In the ATP measurement test, it was measured at the level of 400 RLU or less, which is the standard value of contamination, in both workbenches surface. In additional ATP measurement test, the refrigerator handle in the distribution room was measured above the reference value of 1217 RLU, the vacuum vial shield of the Tech Generator at 435 RLU, and the syringe holder at 1357 RLU. After environmental disinfection, the results were reduced to 311 RLU, 136 RLU, and 291 RLU. Conclusion No contamination by bacteria was found in both workbenches. However, microbial contamination may occur if the use of an exhaust filter or proper hand hygiene is not achieved. Regular inspections and management for aseptic processing themselves will be necessary.

Teachers play a key role in designing a students' learning experience. Teachers are asked to interpret the context in which they are located and to adjust their practice to fit circumstantial needs based on their teacher agency. In this study, we explore the emergence of teacher agency in distance learning caused by COVID-19 and we analyze factors shaping the teacher agency. For this purpose, we interviewed six secondary science teachers who practiced distance learning in 2020. Semi-constructed interviews and their artifacts were collected and analyzed. This study shows that teacher agency is captured when they respond to circumstantial change and modify their practice to achieve their professional purpose or adjust their practice in space for maneuvering or keep their practice consistent. This study also analyzes the factors that affect the emergence of teacher agency in two dimensions. One is individual and the other is contextual. In the individual dimension, educational values shaped by his/her experiences and short/long-term goals for the future support the emergence of teacher agency. In the contextual dimension, there are collaborative and flexible culture shared by the community, co-operation within the teacher community, and material support. On the other hand, in the individual dimension, the teachers' sense of their role, and no reflection for own practice constrain the emergence of teacher agency, and in the contextual dimension, performativity discourse and strong requirement without guidance constrain the emergence of teacher agency. We suggest an effective lens for establishing a strategy that support teachers' professional practice and the emergence of teacher agency.

This paper is to examine philosophy of Jurye(周禮, national rituals) described on GyeongJeMunGam and GyeongJeMunGamByeolJip. As it is widely known, Sambong Jeong Do-Jeon (三峯 鄭道傳), regardless of evaluation by posterity, is definitely a figure who established 500 years of Joseon with almost everything handled by his own hands from presenting founding principle of Joseon to organizing the bureaucratic system. In the third year of King Taejo (1394) with Jurye as an ideological model for social innovation, Jeong Do-Jeon wrote Joseongyeonggukjeon and offered it to the king. Joseongyeonggukjeon is a sort of guide for new codes written by Jeong Do-Jeon as a part of defining culture and institutions of the new dynasty, which is based on Confucianism, the ruling idea of the new dynasty. GyeongJeMunGam supplements the section ChiJeon(治典: Articles for Governing) of JoSeonGyeongGukJeon(the first constitution of Joseon Dynasty) mainly to specify the duties and jobs of the prime minister; and also the duties and jobs of the highest secretaries of the kings, and provincial and county governors, whereas GyeongJeMunGamByeolJip consists of the section GunDo specifying the duties and jobs of the kings and the section Euiron additionally explaining about the kings' duties and jobs in the viewpoint of the philosophy of the Book of Change. That is, GyeongJeMunGam finely describes not only the changes, advantages and disadvantages of prime minister system of every dynasty of China and Korea but also the prime minister's duties/jobs and attitude for kings; and it also specifies the duties and jobs of the kings' highest secretaries, guards, provincial and county governors; on the other hand, GyeongJeMunGamByeolJip says that the king should play the symbolic figure setting their mind in right ways and train themselves with virtue through the idea of GunJuSuShin (君主修身: ) to point out a good and capable prime minister and make him govern the country without using their power fully.

Song Joon Kil(宋浚吉, 1606-1672) intended to establish the subjectivity of people as a "Great Justice". He declared that at that time "Great Justice" was meant to respect 'Ming(明)' and reject 'Ching'(淸). He understood 'Ching' as a country which destroyed the human community and reasoned that if we put Ching's uncivilized behavior out of our mind in favor of the pursuit of present existence and merits, a temporary peace may be got but eternal peace and stability would not be achieved. 'Ming' doesn't refer only to the name of a country, but a country with the capacity to perform 'humanity and justice' with a human culture. On the other hand, he considered 'Ching' to signify the uncivilised country that destroyed or repressed the humanity and peaceful order of the world. He thought the international order can only be maintained under the organization respectful and protective of humanity. He believed a country should act to unify the whole world guaranteeing life and stability. He possessed this cultivated spirit which acted to protect the civilised world from the perils of an uncivilised world. But because of the great famine for a lot of years and the international state(Ming was regressing, and Ching was continuing to make rapid strides) was timely unsuitable to revenge and to wash the shame off. So Song propeled to stabilize the government and to strengthen the national ethics. Song focused on administering the domestic affairs. To him a high priority was a internal affairs, and a low priority was a external affairs[military aggression]. Song considered 'providing for the welfare of the people'(安民) before 'pushing ahead with military aggression'(外攘). And a high priority was 'restoring the people'(養民), a low priority was 'the military affairs'(治兵). Song regarded 'domestic affairs'(內治) as a fundamental affairs. He putted 'to nurse people'(養民) and 'to straighten King's mind'(格君心) first, than 'to buildup military'. His foreign policy was 'respecting Ming' and 'rejecting Ching'. Song was bothered about defining Chosun dynasty's moral obligations to the southern Ming government(1644~46) at Nanjing at that time.

The purpose of this study was to compare Gwonbeop motions among "Gihyosinseo", "Mubiji", "Muyejaebobunyuksokjib" and to analysis catalogue of books on Gwonbeop for comprehensive interpretation in "Muyedobotongji". the conclusion through literature review was as follows. First, There were total 16 references which were composed of 14 references of China and 2 references of Korea. In particular there was no reference of Japan for Gwonbeop. In detail, unrepresentative references of China were "Hanseo", "Gihyosinseo", "Mubiji" and unrepresentative reference of Korea was Muyejaebobunyuksokjib". Second, We compared motions of Gwonbeop between China and Korea. There were located 5 motions such as Gyungakguheese(False Prey Posture), Gigose(Flag Beating Posture), Ahnshichukshinse(Goose Wing Posture), Jumjoose(Picking Elbow Posture), Pogase(Throwing Shelf Postere). In other three references unmentioned "Mubiji" there were located 8 motions such as Jungranse(Spring Railing Posture), Gichukgakse(Ghost Kicking and Leg Striking Postere), Jidangse(Open Finger Attacking Posture), Soodoose(Beast Head Shield Posture) Shingwon(Heavenly Fist Posture), Il-jopyunse(Whipping Lunging Posture), Jakjiryongse(Dragon Prey Snatching Posture), Joyangsoose(Slanting Hero Hand Posture), In two references of Korea there were located 2 unique motions such as Nachaluichoolmun Gakabyunhase(Low Encountering Posture), Gumgyedongnipse(Single Leg Throwing Postere). Third, Most of all we found two kinds of unique motions such as Chukcheonse and Eungswaeik on "Muyejaebobunyuksokjib" and such as Nachaluichoolmun Gakabyunhase(Low Encountering Posture), Gumgyedongnipse (Single Leg Throwing Postere) on "Muyedobotongji". Based on chronological table although "Gihyosinseo" is the longest literature, there was begun changing techniques in details on literatures of Korea. Transformed into techniques of Gwonbeop on Korea could be supposed that those skills were reflected in society and culture of the Joseon Dynasty. To sum it up, Gwonbeop of "Muyedobotongji" was written by "Gihyosinseo", "Mubiji", "Muyejaebobunyuksokjib" but most motions of Gwonbeop were begun to change gradually except 5 motions of "Gihyosinseo". Especially, there were 8 unique motions which could not be found in references of China. Those unique motions of Korea literatures were living proof of attempting transfiguration from motions of China. The significance of this study was to be able to put stepping-stone to interpretate history of Taekwondo which takes center stage on bare hands martial arts and analyzed the meaning of historical martial arts on Gwonbeop in Joseon Dynasty.

The purpose of this study was to analyze the spatial distribution and location factors of startups by generation (young and middle-aged) in Seoul. To this end, a research model was established that included factors of industry, population, and startup institutions by generation in 424 administrative districts using the Seoul Business Enterprise Survey(2018), which includes data on the age group of entrepreneurs. As an analysis method, descriptive statistics were conducted to confirm the frequency, average and standard deviation of startups by generation and major variables in the administrative districts of Seoul, and spatial distribution and characteristics of startups by generation were analyzed through global and local spatial autocorrelation analysis. In particular, the spatial distribution of startups in Seoul was confirmed in-depth by categorizing and analyzing startups by major industries. Afterwards, an appropriate spatial regression analysis model was selected through the Lagrange test, and based on this, the location factors affecting startups by generation were analyzed. The main results derived from the research results are as follows. First, there was a significant difference in the spatial distribution of young and middle-aged startups. The young people started to startups in the belt-shaped area that connects Seocho·Gangnam-Yongsan-Mapo-Gangseo, while middle-aged people were relatively active in the southeastern region represented by Seocho, Gangnam, Songpa, and Gangdong. Second, startups by generation in Seoul showed various spatial distributions according to the type of business. In the knowledge high-tech industries(ICT, professional services) in common, Seocho, Gangnam, Mapo, Guro, and Geumcheon were the centers, and the manufacturing industry was focused on existing clusters. On the other hand, in the case of the life service industry, young people were active in startups near universities and cultural centers, while middle-aged people were concentrated on new towns. Third, there was a difference in factors that influenced the startup location of each generation in Seoul. For young people, high-tech industries, universities, cultural capital, and densely populated areas were significant factors for startup, and for middle-aged people, professional service areas, low average age, and the level of concentration of start-up support institutions had a significant influence on startup. Also, these location factors had different influences for each industry. The implications suggested through the study are as follows. First, it is necessary to support systematic startups considering the characteristics of each region, industry, and generation in Seoul. As there are significant differences in startup regions and industries by generation, it is necessary to strengthen a customized startup support system that takes into account these regional and industrial characteristics. Second, in terms of research methods, a follow-up study is needed that comprehensively considers culture and finance at the large districts(Gu) level through data accumulation.

This study was carried out to acquire basic data for a long-term hydroponic culture through investigating water and inorganic ion uptake characteristics at different EC level of nutrient solution of three tomato varieties. Three different tomato varieties, the European type(cv. Daphnis), the Asian type(cv. Super Doterang) and cherry type(cv. Minichal), were used for the investigation. Also, the deep flow technique(DFT) was applied. The three different electrical conductivity(EC) level(1.0, 2.0, 3.0, and 4.0 dS·m-1) of hydroponic nutrient solution were used as variable. At a high EC level of nutrient solution, the leaf area and fresh weight decreased in the early stage, and its growth(plant height, leaf number, leaf area, fresh-weight) was poor with salt stress. Result showed that the higher the EC level of the nutrient solution, the lesser was water uptake. The water uptake was not significantly different from varieties in the first survey, but In the second survey, the 'Daphnis' did not show a significant decrease in water uptake in the EC level higher than 2.0 dS·m-1., on the other hand, 'Super Doterang' presented very low water uptake. At a low EC level, N, P, and K, were absorbed more than the concentration of the irrigation water, while Ca, Mg, S uptake were low. At a high EC level, almost ions absorbed less than 50% of the initial concentration of irrigation water. Thus, imbalance among ions was severe at low EC level compared to high EC level. 'Daphnis' was a variety that effectively utilize nutrients under nutrient stress, showing high absorption at low concentration condition and low absorption at high concentration condition. However, 'Daphnis' suffered most seriously by absorbing nutrients excessively.

This paper identifies what the theoretical similarities and differences are in the concept of Sangsaeng held by Zhuxi (1130~1200) and Jeungsan (1871~1909). Human beings cannot live alone. For humans to survive, they must live with others. However, humans have an infinite desire not only for survival but also for material things, honor, and power. In other words, humans, on the one hand, seek harmony and symbiosis for survival, and on the other, constantly confront, conflict and compete with one another to satisfy their infinite desires. Thus, human-to-human interrelationship is not a co-prosperity that creates partnerships for harmony but one of adversaries within competition that must be fought and defeated. At the same time, humans can achieve harmony and cooperation by overcoming their infinite desires and realizing morality. Therefore, various social problems that originate from competitive structure, which are dominated by confrontation and conflict, can be solved through human effort and reflection, so that humans can focus on solving social problems by mobilizing their own wisdom. Jeungsan emphasized Sangsaeng as mutual beneficence and it became one of the creeds of Daesoon Thought. In the Neo-Confucianism of Zhuxi, there is an ideology of Sangsaeng as co-prosperity and this is comparable to mutual beneficence in Daesoon Thought. In Zhuxi's terminology it is called 'In (仁), humanity.' In Neo-Confucianism, a harmonious world is achieved by loving people and caring for and nurturing all things when the principles of humanity are realized. This means that when the principle of co-prosperity is realized in Daesoon Thought, there will be no conflict or grudges, and only an acquired vision of reconciliation and mutual beneficence will be achieved. Zhuxi also emphasizes the realization of humanity (cheonli) by eliminating self-interest. At this time, the relationship between humanity and 'self-interest' is similar to the relationship between the mutual beneficence and grievances in Daesoon Thought. Just as the principle of 'In' fosters love among people and the benefit of things immediately after self-interest is removed, the principle of mutual beneficence is realized immediately after grudges are resolved. This achieves an endless of paradise on earth.

This paper examines a social and cultural history of horror films through the keyword "technology", focusing on The Spark of Fear: Technology, Society and the Horror Film (2015) written by Brian N. Duchaney. Science fiction film is closely connected with technology in film genres. On the other hand, horror films have been explained in terms of nature/supernatural. In this regard, The Spark of Fear, which accounts for horror film history as (re)actions to the development of technology, is remarkable. Early horror films which were produced under the influence of gothic novels reflected the fear of technology that had been caused by industrial capitalism. For example, in the film Frankenstein (1931), an angry crowd of people lynch the "monster", the creature of technology. This is the action which is aroused by the fear of technology. Furthermore, this mob behavior is suggestive of an uprising of people who have been alienated by industrial capitalism during the Great Depression. In science fiction horror films, which appeared in the post-war boom, the "other" that manifests as aliens is the entity that destroys the value of prosperity during post-war America. While this prosperity is closely related to the life of the middle class in accordance with the suburbanization, the people live conformist lives under the mantle of technologies such as the TV, refrigerator, etc. In the age of the Vietnam War, horror films demonize children, the counter-culture generation against a backdrop of the house that is the place of isolation and confinement. In this place, horror arises from the absolute absence of technology. While media such as videos, internet, and smartphones have reinforced interconnectedness with the outside world since the 1980s, it became another outside influence that we cannot control. "Found-footage" and "torture porn" which were rife in post-9/11 horror films show that the technologies of voyeurism/surveillance and exposure/exhibitionism are near to saturation. In this way, The Spark of Fear provides an opportune insight into the present day in which the expectation and fear of the progress of technology are increasingly becoming inseparable from our daily lives.
