Ten species of herbae, which have been used to treat cancers in Chinese medicine, were tested to investigate their mutagenieity or antimutagenicity in S. typhimurium TA97, TA98, TA100, TA1S35, and TA1538. Scolopendra centipede was weakly active in reversion of the frameshift mutation in S. typhimurium TA97 strain and the base-pair substitution in TA100 and TA1535 strains. Other herbae such as Coix lachryma, Dianthus superbus, Tricanthoshse kirilowii, Eupatorium formo- sanum, Lithospermum erythrorliizon, Arisaema japonicum, Curcuma aedoaria, Helicteres angustifolia, and Euonymus sieboldianus did not show any of the mutagenic potential, regardless of the metabolic activation with rat hepatic microsomal fraction. Dianthus superbus, Eupatorium formosanum, and Euonymus sieboMianus exhibited suppressive activities on microbial mutagenesis of N-methyl-N-nitrosoguanidine, a basepair substitution mutagen, in TA1535 and TA10G tester strains. The antimutagenic activities of Dianthus superbus and Euonymus sie- boldianus appeared to be dose-dependant.

In deramped synthetic aperture radar (SAR) equipment that utilizes two or more different bands (different center frequencies), if different pulse repetition frequencies (PRFs) are employed when using a single receiver, owing to its economic feasibility, images of other bands may appear and become ghost images. In this study, to determine the exact location of a ghost image illustrated in inverse SAR images, mathematical formulas are adopted to determine the location of the ghost image in the multiband. Even if the bandwidth and PRF are the same, if Tu (unprocessed time interval) is different, we can observe that a ghost image appears near the actual image. If a time delay is noted, the ghost image appears at the same position as that in the absence of a delay. Thus, the effect of ghost images should be minimized by changing Tu.

‘상관적 사유’의 관점에서 본 타로의 ‘순서체계’에 관한 연구-웨이트 덱의 인물카드 1, 2, 3을 중심으로

As a counseling tool, tarot’s “projective techniques” are used by counselors to interpret the inner realm of the client projected on the tarot image. Counselors should be fully aware of the original meaning or intention of the painting drawn on the tarot card. This is because the seriousness of the problem that the client is currently facing is shown by the gap between the picture drawn in the tarot and the picture viewed by the client. An in-depth study of i mages is e ssential to p inpoint the gap b etween t he o riginal drawings and interpretations. However, the tarot is veiled from its origin and original intention of production due to its mystical tendency. Therefore, this study aims at exploring the factors that determine the order of 3 out of the 22 Major cards of the very popular “Waite Deck.” The three cards are “The Magician,” “The High Priestess,” and “The Empress.” To carry out the study, the author first focuses on the unique characteristics of tarot, the “Synchronicity” of “divination,” and the “Correlative thinking” of the “symbol.” Next, based on the original text of the book referred to by the author of the “Waite Deck,” the symbolism of the tarot image and that of the numbers given to tarot are correlatively compared, from the perspective of the East (China) and the West. Studies have shown that the order of card numbers 1-2-3 of the character cards of the “Waite Deck” is intrinsically related to that of the Chinese mythical, cultural, and philosophical symbol of the “Yang-Yin-Yin-Yang hybridization.”

음천간(陰天干)의 처세와 천(天)의 상관관계 연구 − [滴天髓闡微] 「通神論」을 중심으로 −

이현철 온지학회 2025 온지논총 Vol.- No.82

본 연구는 적천수천미(滴天髓闡微) 의 「통신론(通神論)」에서 언급된 비도덕적인 음천간(陰天干)의 처세를 분석하고, 이를 통해 명리학에서 나타나는 양존음비(陽尊陰卑)와 남존여비(男尊女卑)의 왜곡된 도덕관을 규명하며, 현대적 재해석의 필요성을 제기한다. 적천수천미 의 주석에서 임철초는 “음간은 세력을 보면 천박하고 인색하며, 처세에 교만하고 아첨하는 성향이 많다”라며 음간의 비도덕적 처세를 강조하였다. 이에 대해 유성의는 기(氣)의 순수함과 리(理)의 올바름을 통해 음간의 부도덕성을 극복할 수 있다고 제안했으며, 임철초는 이를 선(善)의 실천으로 해결해야 한다고 제안하였다. 본 연구의 주요 문제의식은 첫째, “세상만물 중 왜 인간에게만 도덕적 기준이 요구되는가?” 둘째, “왜 음간이 양간보다, 여성이 남성보다 더 열등하다고 여겨지는가?”에 있다. 이 문제를 해소하기 위해 천(天) 관념의 역사적 변천 과정을 살펴본다. 또한 음양 관념을 다룬 동중서의 춘추번로(春秋繁露) 그리고 삼종지도(三從之道)의 사상을 천간지지(天干地支)에 투영한 소길의 오행대의(五行大義) 도 고찰하였다. 연구 결과, 십천간(十天干)의 도덕적 규정은 주재천(主帝天)과 깊이 연관되어 있으며, 동중서는 주재천의 시각에서 음양과 남녀를 차별적으로 대했다는 것을 알 수 있었다. 또한 소길 역시 오행대의(五行大義) 에 춘추번로 와 삼종지도(三從之道)의 사상을 반영하여 남녀를 차별적으로 대했음을 확인하였다. 결론적으로, 음양의 본질은 상호대립과 상호의존의 평등한 가치에 있다. 그러므로 본고에서는 현대 사회에 부합하는 십천간의 새로운 재해석을 위한 몇 가지 예를 제시하였다. The study analyzes the immoral attributes of Yin Heavenly Stems (陰天干) mentioned in the 「Tong Shen Lun (通神論)」 chapter of Ditiansui Chanwei (滴天髓闡微) , exploring the origins of distorted moral perspectives such as ‘Yang superiority and Yin inferiority (陽尊陰卑)’ and ‘male superiority and female inferiority (男尊女卑)’ in Chinese metaphysics, advocating for their modern reinterpretation. Ren Tieqiao (任鐵樵), in his commentary, emphasizes the immoral traits of Yin Stems, stating, “Once Yin Heavenly Stems gain power, they appear stingy and superficial, often showing arrogance and flattery in social interactions.” In response, You Chengyi (遊誠意) suggests overcoming this immorality through purity of Qi (氣) and correctness of Li (理), while Ren proposes resolving the issue through the practice of Shan (善). The main research questions are: “Why are moral standards uniquely applied to humans among all beings? Why are Yin Heavenly Stems deemed inferior to Yang Heavenly Stems, and females to males?” To address these, this study explores the historical evolution of the Tian (天) concept, examining Dong Zhongshu’s (董仲舒) Chunqiu Fanlu (春秋繁露) on Yin-Yang, and Xiao Ji’s (蕭吉) Wuxing Dayi (五行大義) , integrating Chunqiu Fanlu and the “Three Forms of Subordination (三從之道)” into the Heavenly Stems and Earthly Branches (天干地支). The findings reveal that moral regulations in Chinese metaphysics relate to Zhudi Tian (主帝天, Heaven as Sovereign Deity). Dong Zhongshu differentiated Yin and Yang, men and women, through Zhudi Tian, assigning Yang superior virtue (德) and Yin punitive nature (刑). Similarly, Xiao Ji reflected the ideology of Chunqiu Fanlu and “Three Forms of Subordination” in Wuxing Dayi , reinforcing gender inequality. Consequently, the essence of Yin and Yang lies in their equal value as mutually opposing and interdependent principles. Therefore, this study has presented several examples aimed at the modern reinterpretation of the Ten Heavenly Stems (十天干) in alignment with contemporary society.

Gestalt means shape, pattern, etc., but Gestalt’s theory has a great meaning in that the whole means more than the sum of its parts. In other words, Gestalt psychology is largely based on perceptual experiments, and emphasizes the concept of “organism as a whole”, as opposed to the “atomic” construct that attempts to disassemble everything. The goal of Gestalt Counseling, therefore, is to enable one person to explore, discover, and experience his or her own appearance, behavioral patterns, and his wholeness. The end goal is to integrate all the separate parts and to realize the unexpressed self. In tarot counseling, the interpreter usually interprets the meaning of each of several selected tarot images, accompanied by the principle of perception for interpretation. Therefore, in order to judge whether the client has a ‘organic and integrated healthy perceptual cognitive system’ in recognizing several fragmented tarot pictures, I induced the test subjects to tarot interpretation from the standpoint of the six trends (Figure-ground, Figure-background, Completion, Simplification, Similarity, Proximity, Continuity). As a result, it was found that most of the test subjects were following Gestalt’s ‘Principle of Perception’ in interpreting tarot cards, but it was found some opposite cases as well. This shows that tarot cards can be meaningful as Gestalt’s psychological evaluation tool.
