  • This comparative study attempts to explore in what politico-social context 'Education Welfare Invest Priority Zone Plan' has been developed and to find politico-social implications of Korean EWIPZP through critically comparing the cases of UK and France. Korean financial crisis brought up the importance of 'Education Welfare' turning into a concrete system, 'EWIPZP' in 2003. This educational welfare policy has expanded since 2005 up to now by the changed name of 'Education Welfare Priority Plan' in 2008, that is structurally different from the original framework which was to support schools in educationally disadvantaged areas. Even the cases of EAZ in UK and ZEP in France started by progressive political parties and established on the ground of 'equity' philosophy, turned into the excellence-based equality policy confronting with the harsh condition of neo-liberalistic global economy under the conservative regime. So does Korea under the critics against this tendency. Comparing Korean case with the cases in UK and France, the current Education Welfare Priority Policy in Korea should be back to the original principle of educational equity and transform into the bottom-up bilateral cooperation model from the top-down model by the authorized party itself in order not to be manipulated politically.

  • In this paper, a minimum rotation radius was designed and fabricated to overcome the threshold so that elderly or disabled people who have difficulty moving can move and transfer safely and conveniently in a narrow room. In the indoor environment, where the sedentary culture develops, this study aimed to provide convenience for passengers with fracture diseases, geriatric diseases, and other knee and waist diseases. First, links, seats, armrests, covers, motors, batteries, chargers, controllers, etc. were attached to the frame so that they could be moved and lifted indoors. The product design and structure were designed considering the user's environment and physical characteristics, and IoT functions were added. A driving experiment was performed to confirm the operating performance of the manufactured indoor moving and lifting wheelchair. The performance tests, such as continuous running time, turning radius, maximum actuator load, maximum lift height, sound pressure level, minimum sensing distance of the driving aid sensor, interworking of server and app programs, device compatibility, and duty cycle error rate, were performed. As a result of the test, the built-in wheelchair could achieve the performance test target of each item and operate successfully.

  • This paper comparatively considered how Korea and Japan address the concept of 'postwar' in descriptions of their literary history. In Japan, 'postwar' refers to the period after World War II (Asia-Pacific War). This word implies a variety of contexts such as collapse, poverty, confusion, calendar reform, reconstruction and restoration as well as a series of historical events such as war, war defeat, and American occupation; and so it has been treated in Japanese society a significant period. In the history of Korean literature, it is after national liberation that the word 'postwar' appeared; however, it has usually indicated 'the period after the Korean War.' The question is that although the term of postwar refers to periods after different wars, Koreans used the term of postwar also in the same way as Japan, and their concept of postwar overlaps with the concept of prewar or postwar used in Japan, and accordingly, side effects are produced that fail to grasp properly the independent characteristics and significance of the Korean War. In conclusion, the Korean War brought about contrasting effects on the history of Korean and Japanese literature. While the Korean War meant a start after the war in Korean literature, it became a turning point marking the end of postwar in Japanese literature. Such different perceptions on postwar also have major implications in that perceptions represent postwar discourses in today's Korea and Japan.

  • This research suggests video solutions and efficient implementations for low-budget performances. This study adopts Millumin as a mapping server, which reflects the character of small theatres with a lower budget that doesn't use more than four projectors in a show. By comparing pros and cons of media servers, the study discovers how to employ an appropriate server as well as to participate in a pre-video production stage, which increases the artistry of directing and reduces unnecessary graphics. Meanwhile, with the participation of an interpretive programmer, this study suggests a way to manage the rehearsal time and to increase the artistry of directing. In addition, this study analyses the relationship between the video's visual motive source in the story's development, crisis, climax, twist and the provided narrative based on "Trace U the musical (2018)", by this analyzation, the relationship between storytelling and the video is fully shown. A visual motive is related to the action of actors, the movement of dancers, the music, the lyrics and the lines. Furthermore, the provided narrative confirms that the existence of an actual relationship with the turning point of the plots, characters' emotion, suggestions of sub-plot and the twists of own story. In conclusion, it implies a video of small theatres can not be separated from the probability of the narrative.sh an efficient ad execution strategy that reflected the characteristics of mobile devices.

  • This experiment investigates the characteristics of microorganisms isolated from a medium during cultivation process and reveals the relationship between these microorganisms and the growth of Agaricus bisporus. The domestically grown strains of Agaricus bisporus displayed a higher inhibition growth rate against microorganisms isolated from straw, chicken manure, and medium than imported strains. As for inhibition of mycelial growth among mushroom cultivars of the microorganisms separated by each fermentation step from the mushroom medium, the domestic cultivar, 'Saedo,' grew more vigorously among other cultivars. As the fermentation progressed, it was confirmed that inhibitation of microorganisms against Agaricus bisporus was weakened. A total of 21 strains of microorganisms that promote mushroom growth were isolated in the 4th turning process, and the microorganisms isolated from the mushroom medium affect the growth and as yield of the mushroom through secretory substances.

  • As robot technology advances, research on the driving system of mobile robots is actively being conducted. The driving system of a mobile robot configured based on two-wheels and four-wheels has an advantage in unidirectional driving such as a straight line, but has disadvantages in turning direction and rotating in place. A ball robot using a ball as a wheel has an advantage in omnidirectional movement, but due to its structurally unstable characteristics, balancing control to maintain attitude and driving control for movement are required. By estimating the position from an encoder attached to the motor, conventional ball robots have a limitation, which causes the accumulation of errors during driving control. In this study, a driving control system was proposed that estimates the position coordinates of a ball robot through image processing and uses it for driving control. A driving control system including an image processing unit, a communication unit, a display unit, and a control unit for estimating the position of the ball robot was designed and manufactured. Through the driving control experiment applying the driving control system of the ball robot, it was confirmed that the ball robot was controlled within the error range of ±50.3mm in the x-axis direction and ±53.9mm in the y-axis direction without accumulating errors.

  • This paper describes the production methods that were originally used for an arrow bundle excavated from a Bronze Age residential area in Auraji in Jeongseon, Gangwon-do Province and the conservation treatment process that it subsequently underwent. An arrow conventionally consists of an arrowhead and a shaft. It is rare to excavate a shaft along with an arrowhead in a complete form since the shaft is made of organic materials. Notably, the arrow bundle from the Auraji site is of great significance as it shows traces of tangless stone arrowheads attached to charred shafts and offers an important case of the split end of a piece of a tree being inserted into an arrowhead. For a further examination of the characteristics of the arrows from Auraji, microscopic investigation was conducted and the type of wood used for the arrow shafts was examined. The sequence and direction of processing and the particle sizes of the grinding tools were revealed through the analysis of traces of grinding on the stone arrowheads. The shaft is presumed to have been made from a green length of three-year-old willow (Salix spp.). A curing agent with a high degree of waterproofing and reversibility was used during the on-site curing process according to demands of the surrounding environment, and a technique that the authors call the "Bridge" method was used for emergency collection of the relics. Once the bundle was transferred to the conservation treatment lab, reinforcing materials were carefully chosen as it was important not to damage the relics during the process of turning them for the repair of their reverse sides. For this purpose, artificial clay was selected since it can safely bear a load and has excellent physical properties. Finally, detached parts were rejoined, the relics and their surrounding materials were cleaned, and the bottom sides were finished with epoxy resin prior to the display of the relics at the museum.

  • This paper took Jeonkyeong (典經) of Daesunjinrihoe(大巡眞理會) as the basic text and studied how Kangjeungsan(姜甑山), the Sangje (上帝), had embraced Chinese myth in process of formation of his religious thought focusing on Yan Emperor(炎帝) Shennong(神農) myth and Shanrangang(禪讓) myth (namely Danchu myth). First when we examine the myth surrounding Kangjeungsan's birth, it deeply emraced a feeling-birth myth(感生神話), we could realize that this is a universe motif through myth of hero birth in East Asia. Further judging from the analysis of geographic space of Kangjeungsan's activity, it included a variety of mythical and Daoist related place names. I think this is because of the fact that birth place of Kangjeungsan and the surrounding area is the locality of Xian(仙) tradition where major characters of Danhak sect(丹學派) have been turned out, and that Korean way of Xian suppressed by the regulatory system has been widely rooted in the public. Especially it's interesting that Jeungsan, the pen name of Kangjeungsan, ambiguously connotes Siru mountain(甑山), a place of his training, and the spiritual realm of the 『Zhouyicantongqi(周易參同契)』. Then I examined the God of fire Shennong myth which has been actively admitted and embraced by Kangjeungsan. Kangjeungsan put the root of his pedigree on Shennong and there is a close affinity between Shennong and Dongyi(東夷) such as Buyeo(夫餘), Goguryeo(高句麗), etc. These Dongyi spirits are losers against the Chinese major myth and beings of ressentiment. At the same time the predecessor of Jiutianyingyuanleishengpuhuatianzun(九天應元雷聲普化天尊) who shares mythical characteristics with the God of fire Shennong was a formerly Taishi(太師) Wenzhong(聞仲) of Yin(殷) dynasty. He was defeated and died by Zhou(周) dynasty, and was deified. The fact that Kangjeungsan regarded himself as a descendent of Shennong and possessed divinity of Jiutianyingyuanleishengpuhuatianzun connotes that he represents all beings of ressentiment such as family of Yin and Dongyi. However, Kangjeungsan set a religious milestone by turning revenge for such ressentiment at tribe level into religious sublimation. At the end Shanrang myth which has been critically embraced by Kangjeungsan was reviewed. According to the existing Shanrang myth, Danchu(丹朱) was unworthy and not succeeded in the succession to the throne. Then good natured Emperor Shun(舜) succeeded to the throne from Emperor Yao(堯). However, the reality of Shanrang myth was a violent change of sovereign power and Danchu was a victim in the process of such violent change. Kangjeungsan shrewdly grasped the reality of ancient China and cast light on presence of Danchu. And he emphasized the need of religious sublimation of revenge, Haewon(解冤). His such awareness of culture had a close relation with revisionist standpoint of independent Danhak sect expressing a skeptical glance at systematic, commensurate and authentic historical view of Chinese civilization. And further Kangjeungsan cosmologically and causationally reinterpreted revenge of Danchu. He established a universal salvation theology which has a corresponsive connotation in regard to embracement of Shennong myth. In conclusion, embracement of Chinese myth by Kangjeungsan was a creative work of reinterpretation resulting in an inherent religious connotation through a process of appropriation, that is independent and selective introjection.

  • This study was designed to look into whether there is any mediated effect of psychological well-being and empowerment on the path of the negative emotions of mothers from multi-cultural families turning into the life satisfaction and tried to demonstrate empirically factors to mitigate the decline in the life satisfaction due to negative emotions of mothers from multi-cultural families. In addition, we verified the differences of psychological factors according to the characteristics of the sociology of population of mothers from multi-cultural families. For this, the survey was conducted with 400 mothers from multi-cultural families across the nation. The results are as follows. First, in case of negative emotions, there were differences among groups depending on ages, years of marriage and educational background. In case of psychological well-being and empowerment, there were differences among groups with different age, years of marriage, their own or their spouse's educational background. Second, as a result of looking into the path through which negative emotions turned into life satisfaction, there were the path effects between negative emotions and empowerment, between negative emotions and life satisfaction, and between psychological well-being and life satisfaction. This means that dealing properly with negative emotions can have positive impacts on the three dimensions of psychological well-being, empowerment, and eventually the life satisfaction. This study is meaningful in that it took psychological factors of mothers from multi-cultural families into consideration and the results can be used as useful data to come up with political measures for mothers from multi-cultural families in the future.

  • Five commercially available edible sweeteners are used as diet products because they can replace sucrose. In studies on the effects on animals and the human body, stability has been proven by excreting-oriented studies with characteristics of animal cells, and accumulation in small amounts has been ignored. On the other hand, plants can absorb, degrade, and accumulate foreign substances, so the effect of degradability and accumulation potential can be studied using plants. Metabolic effects in plants of commercially available saccharin and acesulfame potassium (Ace K) were tested using germinated barley and bean sprouts. In germinated barley and bean sprouts, saccharin and ace K showed inhibitory effects on plant growth in all organs from low concentrations in leaves, stems and roots. In addition, it can be observed that the symptoms of death appear clearly over time, so it can be seen that they are accumulated in the body of the plant. As the accumulated amount increases, the toxic effect increases and the plant reaches a state where it is unable to metabolize, turning black from the tip of the leaf and reaching a state of death. In order to remove the accumulated artificial sweetener, recovery was attempted by culturing in distilled water, but it acts as a substance that is not degraded and dies without avoiding toxicity. Saccharin and ace K cannot be excreted from the cell. Its toxic effects are thought to be persistent, inhibiting growth and eventually leading to cell death.
