Recently, because of COVID-19 cases emerging due to the air conditioning system of buildings, the spread of infectious bacteria through indoor airflow is receiving continuous attention. Since the Outpatient Department maintains general air-conditioning operation conditions 20% outdoor-air and 80% recycled air, the exhaustion of infectious air currents is not fast enough at times when the number of visitors increases, which might lead to the nth infection. Due to this, in preceding research, the number of infectious bacteria depending on the number of visitors was predicted using ML algorithms. In this research, the characteristics and behavioral variables of visitors were applied to the algorithm used in the preceding research to predict once more the number of infectious bacteria based on the behavior of visitors. Also, the predicted number of infectious bacteria was used to analyze airborne infectious bacteria by room and by time of the day after categorizing the number of visitors into days of the week in which it is at its maximum, and days of the week in which it is at its minimum. This research results are expected to be used as baseline data on air-conditioning system control algorithms that respond to changes in the number of visitors and infectious bacteria by room in the Outpatient Department.

Purpose: The purpose of the study is to find out the effect of objeciteifd body consciousness & body esteem on self-compassion & self-efficacy for female Yoga participants. Method: To do this, 462 effective sample data were selected using purposeful sampling of participants who live in G, B, G-do, J-do. Exploratory factor analysis, Cronbac’hs α, correlation analysis, and simple regression analysis in SPSS 23.0 FOR Windows statistical package was used. Results: The results of this study are follows. 1) The sub factors of bojectified body consciousness, body shame, positively influenced the negative self-compassion, which is a sub factor of self-compassion. Body surveillant, which is sub factors of objectified body consciousness, negatively influenced the negative selfcompassion. 2) Body shame, which is a sub factor of objectifie dbody consciousness, negatively influenced self-confidence, which is a sub factor of self-efficacy. Body hsame and control belief which are sub factor s of objectified body consciousness, positively influenced self-regulatory efficacy. 3) The sub factor of selfcompassion and appearance esteem, which are sub factors of bod yesteem, positively affected the positive self-compassion which is a sub factor of self-compassion. 4) Teh sub factor of body esteem, bodily function esteem had a positive effect on self-confidence and appearance esteem which is a sub factor of body esteem positively affected the self-regulatory efficacy which is a sub factor of self-efficacy. Conclusion: In summary, as a way to improve the self-mercy and self-efficacy of women participating in yoga practice, it is necessary to raise positive thinking about the objectivity and body consciousness of objectified body consciousness.

Yuzu (Citrus junos) undergoes traditional processing to create preserved yuzu with a sugar content of 50%. This study aimed to produce low-sugar yuzu syrup using artificial or natural sweeteners instead of sugar. Among artificial sweeteners, maltitol showed minimal browning and lack of deposition at high temperatures. The addition of xanthan gum (0.2%) and carboxymethyl cellulose (0.2%) resolved the issue of layer separation and viscosity decrease of yuzu syrup. Alternatively, grain syrup, a natural sweetener, improved viscosity and homogeneity without the additives. Yuzu syrups were developed using yuzu juice and preserved yuzu, with maltitol (20~40%) or grain syrup (50~70%) as the sweetener. Yuzu syrups containing 35% maltitol (M35) or 55% grain syrup (G55) had less than 5% and 10% free sugar, respectively. These syrups exhibited taste patterns similar to commercial yuzu syrup in analysis using an electronic tongue. Furthermore, M35 and G55 contained yuzu flavonoids at concentrations of 19.82 mg/g and 24.09 mg/g, respectively. Antioxidant activity (DPPH, ABTS radical scavenging) of M35 and G55 was equivalent to 10.55, 17.59 mg/100 g of Vitamin C and 97.39, 33.92 mg/100 g of Vitamin C, respectively. Consequently, M35 and G55 offer promising alternatives to preserved yuzu, providing low-sugar yuzu syrups enriched with functional ingredients.

書寫道具의 발달과 漢字字形의 변천

The Chinese Character was made about 3,000years ago. During these 3,000years, the character style has been changed several times, based on writing tool change and political reasons. At first they wrote the character on turtle bone using sharp bone or sharp stone etc. This kind of character is called 甲骨文. In the 周 dynasty, people began to use bronze; they wrote characters on the bronze, and these kinds o characters are called 鐘鼎文 or 金文. In 秦 dynasty, the emperor 秦始皇 decided to consolidate characters, so he let 李斯 make 小篆, which is more simplified than 鐘鼎文. And from 秦 dynasty people invented brush and ink. At that time they often wrote on bamboo or silk. In 秦 dynasty there were many slaves in prison, the court needed more simple characters that could be written quickly and easily for their records, so they made 隸書. In Han(漢) dynasty, they invented paper, so it became more easier to write. Since Han dynasty the character style became more various; there are 草書, 行書, 楷書. The Chinese character not only is used in China, but also used in several neighbouring countries like Korea, Japan and Vietnam, so these areas are called Chinese character sulture zones. Synthetically speaking, the Chinese character has been changed as following: 甲骨文(殷) →種鼎文(周) 주文(周) →小篆(秦) →隸書(秦~漢) →草書 (漢) →行書 (漢) →楷書 (漢)

반일의 비판지정학 : 유니클로 광고 사태와 불매운동

박윤하 한국공간환경학회 2021 공간과 사회 Vol.31 No.3

이 논문은 비판지정학에 대한 논의를 기반으로 ‘위안부 모독’ 의혹을 불러일으킨 유니클로 광고를 둘러싼 사회적 논란에 대한 고찰을 통해 한국사회에서 일본에 대한 특정한 담론과 실천이 어떻게 발전하였는지 살펴보았다. 구체적으로 유니클로 광고를 둘러싼 논란이 발생한 사회적·지정학적 맥락을 살펴보고, 유니클로 광고가 생산한 담론이 불매운동, 시위 등 다양한 사회적 실천으로 확장되는 과정을 분석하였다. 그리고 이렇게 아래로부터 나타난 지정·지경학적 담론과 실천이 대항 담론 및 실천과 경합하고, 사회의 다른 갈등 지형과 접목되는 과정을 살펴보았다. 이를 통해 이 연구에서는 민족주의를 국가의 기획으로 단순화하는 접근을 비판하고, 비정부 주체인 기업이 광고를 통해 국가 간 갈등에 상당한 영향을 미칠 수 있는 유의미한 지정학적 행위자임을 강조하였다. 또한 기존의 비판지정학이 텍스트 해석에 초점을 둔 것에 대해 비판을 받았던 것에 반해, 이 연구에서는 담론의 생산, 다양한 실천으로의 확장, 그리고 정치적 경합 등의 역동적인 과정에 대한 분석을 통해 비판지정학 연구의 지평을 넓히는 데에도 일조하였다. Based upon the discussions of critical geopolitics, we explore how particular discourses and practices on Japan emerged and developed in South Korea through social issues sparked by the Japanese clothing brand Uniqlo’s controversial commercial that was accused of mocking South Korea’s victims under Japan’s colonial rule. Specifically, we examine the social and geopolitical context in which the controversies around the Uniqlo commercial erupted and how the discourses caused by this ad evolved into various social practices such as boycotts and protests. In addition, we investigate how bottom-up geopolitical and geoeconomic discourses and practices intensely contested counter-discourses and practices and were grafted onto another social conflict. Through this analysis, we criticize the approach to naturalize nationalism as a tool for strengthening state legitimacy and note private companies (non-state actors) as a significant geopolitical player who can bear on inter-state conflict. While existing critical geopolitical approaches have been criticized for textualism, we expect that our analysis can enrich critical geopolitics through shedding light on dynamic processes of production of discourses, expansion into various practices and political contestations.
