The anti-oxidant activities of Acanthopanax senticosus stems were investigated. The n-BuOH fraction of A. senticosus stems exhibited a significant decrease in serum transaminase activities elevated by hepatic damage induced by CCl$_4$-intoxication in rats. The n-BuOH fraction inhibited the sGPT activities by 65.79%. The n-BuOH fraction showed the increase in the anti-oxidant enzymes such as hepatic cytoso1ic superoxide dismutase, catalase and glutathione peroxidase activities by 30.31, 19.82 and 155%, respectively, in CCl$_4$-intoxicated rats. These results suggest that the stems of A. senticosus possess not only the hepatoprotective, but also the anti-oxidant activities in rats.

Purpose: Developmental disabilities (DDs) are a global childhood problem whose prevalence is rising, with a disproportionate impact on individuals in low-and middle-income countries. However, data on the prevalence of DDs in the Arab world are limited. This review highlights what is currently known about the prevalence and risk factors of DDs in preschool children in the Arab world. Methods: PubMed, Cochrane Library, Scopus, CINAHL, Science Direct, and Google Scholar were searched for publications on DDs among preschool children in the Arab world. Only 14 studies were identified in the literature, from 12 Arab countries. Results: The overall estimated prevalence of DDs among preschool children in the Arab world is 27.5%. An analysis of risk factors for DDs showed that child-related, maternal, and family-related factors account for a significant cumulative risk of developing DDs in preschool children. Maternal factors, such as antenatal and perinatal complications, were the most common risk factors. Conclusion: The prevalence of DDs among preschoolers is significantly high in the Arab world, which emphasizes the importance of the early detection and diagnosis of DD, as well as its associated risk factors.

The purpose of this study is to suggest that activities consisting of sympathy and gratitude are the way to healing. In our team's Hope World (希望世上), we changed the lyrics of GunbamTaryeong, which Koreans know the most, to create a healing Taryeong. The iterative refrain changed to "It's nice, it's hope, it's a good world for everyone." "The Wind Blows, Spring Has Come, The Moon Is Bright" will be the beginning of each chapter in GunbamTaryeong. It looks like a bright lyric, but it also shows both sides. All members participated in changing the lyrics, harmonizing the lyrics and rhythm, preparing props, playing musical instruments, and exciting performances. Therefore, it can be said that it is the story of healing where everyone is together. The song of Hope World is a real Taryeong that heals those who plan together, sing together, play musical instruments together. It's a "hope-Taryeong (希望打令)" who dreams of a "everyone good world." It's a Taryeong that lingers in my mouth and comes to mind. In this way, activities consisting of mutual cooperation and love doubled gratitude and sympathy for each other, and we think healing was achieved in the process. In this study, we suggest that sympathy and gratitude are perhaps the first steps towards healing. The Hope World Song (希望世上歌) is available on our channel YouTube (https://youtu.be/hgPiD4g2-iM).

Lactobacillus johnsonii 7409N31 was isolated from the feces of a healthy 11-day-old Hanwoo calf from a farm in Geochang-gun, Gyeongsangnam-do, Korea. The genome of the strain was completely sequenced using the PacBio RSII sequencing system, and it was confirmed that it was composed of one circular chromosome. The size of the entire genome was 2,198,442 bp, and it had 35.01 mol% guanine + cytosine (G + C) content and 2,222 protein-coding sequences, 24 rRNA, 3 ncRNA, and 112 tRNA genes. Strain 7409N31 possessed genes encoding enzymes involved in the hydrolysis of both fibrous and non-fibrous carbohydrates. These data provide a comprehensive theoretical understanding for developing industrial probiotic feed additives that improve nutrient digestibility.

가상 공간의 익명성으로 인하여 개인들은 물리적 세계와 다른 자기를 가상 세계에서 창조한다. 본 연구의 목적은 물리적 세계의 자기와 가상 세계의 자기 사이에 존재하는 차이가 개인의 온라인 커뮤니티 활동에 어떠한 영향을 미치는지 고찰하는 것이다. 먼저, 자기차이이론(Self discrepancy theory)을 기반으로 자기차이에 대한 개념적 정의를 도출하고 자기차이를 가상 세계 내에 존재하는 자기차이(Self-discrepancy in virtual world)와 물리적 세계와 가상 세계 사이에서 존재하는 자기차이(Cross-world self-discrepancy)로 세분화 하였다. 또한 각각의 자기차이를 요인 분석을 통하여 개인적 자기차이(Personal self-discrepancy)와 사회적 자기차이(Social self-discrepancy)로 구분하였다. 도출된 서로 다른 유형의 자기차이가 개인의 커뮤니티 지속사용 및 지식 기여 사이에 어떠한 영향을 미치는지 이론적 모형을 개발하고, 수집된 300개의 설문자료를 바탕으로 이를 검증하였다. 분석 결과, 가상 세계 내에서 존재하는 자기차이는 지각된 자기표현 유용성에 부의 영향을 미치는 반면, 가상 세계와 물리적 세계 사이에 존재하는 자기차이는 자기표현 유용성에 정의 영향을 미치는 것으로 나타났다. 또한 지각된 자기표현 유용성과 사용 용이성은 커뮤니티 지속 사용과 지식기여에 모두 정의 영향을 미치는 것으로 나타났다. 본 연구는 전통적인 자가차이 이론에서 논의되어온 자기에 대한 개념을 가상세계의 자기로 확장하였으며, 서로 다른 유형의 자기차이가 개인의 행위에 미치는 영향을 온라인 커뮤니티 정황에 적용함으로써 자기 개념에 대한 이론적 발전에 기여하였다.

Ginsenosides, which are the active materials of ginseng, have biological functions that include anti-osteoporotic effects. Aqueous ginseng extract inhibits osteoclast differentiation induced by receptor activator of NF-${\kappa}B$ ligand (RANKL). Aqueous ginseng extract produces chromatography peaks characteristic of ginsenosides. Among these peaks, ginsenoside Re is a major component. However, the preventive effects of ginsenoside Re against osteoclast differentiation are not known. We studied the effect of ginsenoside Re on osteoclast differentiation, RANKL-induced tartrate-resistant acid phosphatase (TRAP) activity, and formation of multinucleated osteoclasts in vitro. Ginsenoside Re hampered osteoclast differentiation in a dose-dependent manner. In an in vivo zebrafish model, aqueous ginseng extract and ginsenoside Re had anti-osteoclastogenesis effects. These findings suggest that both aqueous ginseng extract and ginsenoside Re prevent bone resorption by inhibiting osteoclast differentiation. Ginsenoside Re could be important for promoting bone health.

Tabriz under Mongol Ilkhanate rule commanded a global reach in the thirteenth-century Afro-Eurasian world. Tabriz functioned during this period not only as a commercial emporium and diplomatic center but as a seat of innovative artistic and intellectual activity. Consideration of Tabriz as a world historical city offers insight into the economic and social dynamics that shaped a critical passage in Eurasia's history including regions of the Mediterranean and East Asian zones.

In this paper, a programming system for robot-based manufacturing cell which can control and simulate manufacturing devices as well as robots in workcell is proposed and developed. The system is based on world model, and modem textual and object-level robot programming language and interactive graphic world modeler are used to construct and exploit world model. Graphic simulation is used as an efficient and easy to use debugging or verifying tool for user written robot programs. Machine dependency is minimized by adopting the hierarchical control structure and by assuming all the workcell components as virtual ones.
