Objectives: Cannabis root is a medicinal plant that has been used in traditional medicine around the world. However, in previous studies using simple extracts, the biological activity was not relatively prominent compared to other herbal medicines. The aim of the present study is to confirm the enhancement of anti-inflammatory activity and bioactive compound of Cannabis root extract prepared by combined processing process. Methods: A series of processes including repeated steam and dry, fermentation, hydrothermal extraction and ethanol extraction was applied to Cannabis root. The antioxidant content of cannabis root extracts obtained through a combined processing process was investigated by analyzing the total phenolic, tannin, and flavonoid contents. Anti-inflammatory effects were tested in LPS-treated RAW264.7 cells. The anti-inflammatory mechanism was examined by western blot. Finally, the component profile of Cannabis root extract was analyzed using High Performance Liquid Chromatography (HPLC) and Thin layer chromatography (TLC). Results: The cannabis root extract prepared by complex processing process had higher antioxidant and anti-inflammatory effects than simple extract. Total phenolic and tannin contents were significantly increased, and DPPH free radical inhibition activity was strengthened by combined processing process. Increased NO production and iNOS expression in LPS-treated RAW264.7 cells were decreased in a concentration-dependent manner upon extract treatment by complex processing process. Additionally, the Stigmasterol content of Cannabis root extract was increased through a complex processing process. Conclusions: Further research is needed on the mechanisms and substances that exhibit the anti-inflammatory effects of Cannabis roots extract prepared by complex processing process.

Purpose: This study aimed to investigate the influence of fall risk, fear of falling, and social support on older inpatients’ fall prevention behaviors. Methods: The participants were 105 older inpatients. Data were analyzed using descriptive statistics, independent t-test, One-way ANOVA, Pearson’s correlation coefficients, and multiple regression analysis using the SPSS program. Results: The mean fall risk, fear of falling, social support, and all prevention behaviors were 58.05±28.27, 2.47±0.67, 3.58±0.63, and 2.93±0.48, respectively. There were significant differences in fall prevention behaviors by sex, and fall related to education experience. Fall prevention behaviors were associated with fall risk, and fear of falling. The factors influencing the fall prevention behaviors of the older inpatients were sex, fall related to educational experience, fall risk, and fear of falling. It was found that 21% could explain fall prevention behaviors. Conclusion: The results indicate a need to develop a fall prevention education program, including intervention, to reduce the fear of falling among older inpatients. .

인스타그래머블 전시 관람의 지속적 이용 의사에 영향을 미치는 요인에 관한 연구: <우연히 웨스 앤더슨> 전시 사례를 중심으로

유가람,이보아 한국컴퓨터정보학회 2022 韓國컴퓨터情報學會論文誌 Vol.27 No.12

This study sheds light on the Instagrammable features and viewing experiences of <Accidentally Wes Anderson (AWA)>. A research model and hypotheses are formulated using variables including Experience Quality (EQ), Perceived Value (PV), Attitude toward AWA (ATAWA) and Behavioral Intention toward AWA (BITAWA). Although AWA has strong the Instagrammable features in terms of PV, it provides aesthetic or healing experience rather than a pleasure. PV has a significant correlation with DOS and DOI, but it does not influence on BITAWA. In addition, DOS has a positive impact on the increase in DOI, length of viewing time and intention to upload and share photos on Instagram. 본 연구는 <우연히 웨스 엔더슨(Accidentally Wes Anderson, 이하 AWA)> 전시의 인스타그래머블 특성과 관람 경험을 실증적으로 접근하기 위해 경험 품질, 인지된 가치, 이용 태도, 지속적 행동적 이용 의사 등의 변인을 중심으로 연구 모형과 가설을 설정했다. 인지된 가치의 관점에서 상기 전시의 인스타그래머블적 특성은 강했지만, 경험 품질 측면에서 전시는 유희적이기 보다는 심미적이거나 치유적 특성이 높게 나타났다. 상술한 인지된 가치는 전시만족도 및 전시몰입도와 상관관계를 가졌지만, 행동적 이용의사에는 영향을 미치지 못했다. 또한 전시만족도는 전시몰입도, 관람소요시간, 인스타그램에 사진 게시 및 공유 의사의 증가에 긍정적인 영향을 미쳤다.

본 연구는 확장된 기술수용모델을 기반으로 VR 게임 사전 경험이 있는 모집단(n=70)을 대상으로 몰입형 VR 엑서게이밍의 사용자 경험을 정량적으로 분석했다. 연구 결과, 설문참여자들은 VR 엑서게이밍 콘텐츠가 흥미도와 스트레스 해소 기능이 높을수록 콘텐츠가 운동에 유용하다고 평가했다. 이러한 유용성은 특정한 이용 태도와도 상관성이 나타났는데, VR 엑서게이밍이 여가 활동과 체력 증진에 유용하다고 인지할수록 사용자들의 만족도와 콘텐츠에 대한 몰입도가 높아졌다. 사용자가 콘텐츠를 통해 강한 즐거움을 느낄수록, 자신이 헤비 유저라고 생각할수록 몰입도가 증가하였다. 또한, 조작 방법 및 게임 이용 방법에 익숙하다고 생각할 때도 몰입도가 높아졌다. 사용자가 운동 시간을 자유롭게 조절할수록, 콘텐츠 내용의 난도가 낮을수록 현실에서 운동하는 것과 같은 운동감을 느꼈다. 마지막으로 만족도와 몰입도가 높을수록 향후 헤비 유저로의 발전 가능성이 큰 것으로 도출되었다. Based on an extended technology acceptance model, this study quantitatively analyzed the user experience of immersive virtual reality (VR) exergaming among a sample of people (n=70) with prior experience of VR gaming. The results showed that the more enjoyable and stress-relieving the VR exergaming content was, the more useful it was perceived to be for exercise. This usefulness also correlated with specific usage attitudes: the more users perceived VR exergaming as useful for leisure and exercise, the more satisfied and immersed they were in the content. The degree of immersion increased when users perceived a pleasurable feature of the VR content, when they considered themselves heavy users, and when they perceived ease of use with the controls and how to engage in the game. The more self-control they had over their exercise time and the less challenging the content, the more they experienced a sense of physical exercise. Finally, the more satisfied and immersed users were, the more likely they were to say they would become heavy users in the future.

코로나19로 촉발한 비대면 사회에서 메타버스(Metaverse)가 주목받기 시작하면서 개방, 참여, 공유의 특징을 바탕으로 한 적극적인 소통의 매개로 이용률이 증가하고 있다. 이에 따라 다양한 브랜드들이 제품 및 서비스를 비롯해 시스템 등의 직 · 간접적인 경험의 기회를 제공하고 있다. 미디어의 다양화는 소비자의 라이프스타일과 인구학적 속성에 따라 구분되는데, 본 연구에서는 라이프스타일의 유형을 가족중심 외향개인형, 내향적 자유주의형, 내향적소비자형으로 구분하고 이들의 라이프스타일에 따라 광고효과 인식의 차이가 유의하다는 것을 검증하였다. 또한 광고 관심도, 광고 이해도, 광고 기억도의 긍정적인 광고효과 인식과 광고 침입성과 광고 회피의 부정적인 광고효과 인식이 광고태도, 브랜드 태도, 구매의도에서 차이가 있음을 확인하였다. 이러한 연구는 라이프스타일 유형에 따른 소비자의 가치관과 구매습관을 파악하고 이들의 소비행동을 분석하여 시장 세분화를 통한 광고 및 마케팅 전략 수립이 가능하다는 점에서 연구의 의의가 있을 것이다. 또한 라이프스타일 유형별 광고효과 차이를 검증함으로써 향후 가상세계 내에서의 광고효과를 향상할 수 있는 방안을 제시한다는 점에서 실무적, 학술적 시사점이 있다. As Metaverse begins to attract attention in a non-face-to-face society triggered by COVID-19, the utilization rate is increasing through active communication based on the characteristics of opening, participation, and sharing. Accordingly, various brands are providing opportunities for direct and indirect experiences such as products and services and systems. The diversification of media is classified according to consumers lifestyles and demographic attributes, and in this study, the types of lifestyles were classified into three types: creation-oriented, self-centered responsibility, and introverted consumers, and it was verified that the difference in perception of advertising effects was significant according to their lifestyles. In addition, it was confirmed that there were differences in advertising attitude, brand attitude, and purchase intention between perceived positive advertising effects of advertisement interest, advertisement understanding, and advertisement memory, and perceived negative advertising effects of advertisement intrusion and advertisement avoidance. Research will be meaningful in that it is possible to establish advertising and marketing strategies through market segmentation by identifying consumer values and purchasing habits according to lifestyle types and analyzing their consumption behavior. In addition, there are practical and academic implications in that it presents a plan to improve advertising effects within the virtual world in the future by verifying the difference in advertising effects by lifestyle type.

Objectives: This study examined the effects of hostile attribution bias and justice sensitivity (victim and perpetrator sensitivity) on cyberbullying perpetration in middle school students and investigated whether justice sensitivity moderated the relationship between hostile attribution bias and cyberbullying perpetration. Methods: The participants comprised 664 middle school students (309 boys and 355 girls) from five middle schools in Seoul and Gyeonggi-do. Cyberbullying perpetration, hostile attribution bias, and justice sensitivity were measured using the Bullying/Victimization Questionnaire (BVQ), a hypothetical-situation instrument, and the justice sensitivity inventory for children and adolescents, respectively. The data were analyzed by means of descriptive statistics, a multiple regression analysis, and PROCESS MACRO methods (model 2) by Hayes (2013). Results: Hostile attribution bias and victim sensitivity had a positive influence on cyberbullying perpetration. Victim sensitivity was also found to moderate the relationship between hostile attribution bias and cyberbullying perpetration. Conclusion: Hostile attribution bias and victim sensitivity increased cyberbullying perpetration; the effect of hostile attribution bias on cyberbullying perpetration differed depending on the level of victim sensitivity.

조선후기의 문헌 『사의당지』에 나타난 고택의 입지 및 공간구성에 관한 고찰

This study has focused on analysis of the location and spatial composition about a traditional house recorded on the book, 『Saeudangzi』, which was written by Hong, Kyungmo(1774-1851). Saeudang(四宜堂), the Hong’s Seoul mansion[京邸], recorded on 『Saeudangzi(四宜堂志)』, was one of the most typical house of Sadaebo(士大夫: nobleman) in Chosun dynasty and unfortunately it does not exist at this time. It can be just imagined and analyzed through the record.「Saeudnagzi」, one of 『Gwanamjunseo』 which has 32 different writings, has respectively contents such as Wonseo(原書: preface), Dangwoo(堂宇: house), Hyungseung(形勝: landscape), Jomang(眺望: perspective), Hwasuk(花石: flowers and stones), Seohwa(書畵: writings and paintings), and Giwan(器玩: ceramics). In this research, I try to represent visual ground plans and analyze the spatial composition of the mansion based on Dangwoo(堂宇), Hyungseung(形勝), Jomang(眺望), Hwasuk(花石) among these contents. The spatial composition, location, garden landscape and so on of Saeudang are as below. 1. The building was consisted of about 100 rooms, which was sort of a big mansion. At first, it was princess Jungmyung's house bestowed from King Injo and was considered to be the scale of a castle house. After 150 years from that time, it was recorded on the book by Hong, Kyungmo. 2. The surrounding area of Saeudang as the location was a hermitage in a big city and a view point to see various mountains, hills, and stream. 3. The inner quarter of Saeudang had a two-story pavilion and was nearly opposite ‘ㄴ’ -shaped, which was adjoined the beneath of one was opposite ‘ㄱ’ -shapred. The 1st floor used as two servants’ quarters and two warehouses. The 2nd floor was a Ru-meru like a loft. 4. The records about building composition, placement, and the number of rooms in a building were very detail, whereas there are no clues which I can estimate of respectively distances between buildings. The book-Saeudangzi just tell us a garden's scale in the abstract like that garden's width is about twice of length and the garden is as wide as carts can pass the yard of one. 5. There are a Tai Hu-stone, 5 oddly-shaped stone, and 23 species of plants on flower stairs and yards. In addition, many potted plants(bonsai) of small trees, flowers, and stones were also on the stairs, which were consisted 17 bonsais with flowers and 4 bonsais with stones. 6. Flower stairs were respectively located on the back yards of Sooyarkdang and Jungdang. Moreover, the south yard of Saeudang had a flower bed and a pine-stair. According to 「Saeudangzi」, it just recorded a Tai-hu stone was on a yard, so I couldn't figure out where the stone was. 7. The fact that there were 3 stables in the servants’ quarters, which were in front of Saeudang, reveals a number of people often attended some poetry parties in the mansion. Furthermore, a floor at outer servants’ quarters were provided to guests as the rest place. 8. The meaning of Terms, Gye(階), Gye(堦), and Che(砌), are almost same as ‘stairs with stone’. Especially, Gye(階) and Gye(堦) have the exactly same meaning, but chinese character is different between both. The meaning of Che(砌) is also included that lots of stones are deposited in heaps.
