This study focused on Issey Miyake’s 14 womenswear collections from spring 2018 to fall 2024. Reviews and reports on these collections and the designer were collected from the American Vogue and the Women’s Wear Daily websites using the keyword “Issey Miyake.” Drawing upon the dress criticism model, this study analyzed the form of Miyake’s fashion designs identifying styles, descriptive features, and aesthetic values through the collection photographs. Implicit evaluations were derived through external interpretations and sociocultural analysis based on reviews and reports of Miyake’s collections and designs. The results were as follows: Miyake’s fashion design is avant-garde in style. Descriptively, Miyake introduced variations in silhouette through the three-dimensionality of pleats, exploring a new sculptural order. The aesthetic values of Miyake’s works extend beyond the fashion show realm, embodying natural beauty wearable in daily life, artistic beauty through the three-dimensionality of pleats, and a pursuit of new aesthetic values challenging existing systems and traditional norms. Externally interpreted, Issey Miyake is recognized for his diverse, practical, and innovative designs, and as the first Japanese designer to present shows in Paris. Sociocultural interpretations characterize of Issey Miyake’s works as a blend of tradition and modernity, an expansion of form through pleats and three-dimensional sculptural qualities, the result of ongoing research and development, possessing timeless qualities transcending eras, and a pursuit of practicality and artistic excellence.

기후변화로 인해 국내에서의 기온, 강수량, 호우일수가 증가 할 것으로 예측됨에 따라, 토양 답압과 높은 불투수면적 비율이 나타나는 도심지를 중심으로 정원과 공공녹지에 활용되는 식물 소재에 있어 내침수성이 중요한 특성으로 부각될 가능성이 높 다. 그러나 내침수성 식물소재에 대한 대다수의 문헌은 재배경 험이나 각 종의 서식지 환경에 기반하고 있는 경우가 많아 실험 적 검증이 필요하다. 따라서 본 연구는 토양수분함량이 높은 서식지에서 기원한 골등골나물(Eupatorium lindleyanum DC.), 새등골나물(E. fortunei Turcz.), 좀개미취(Aster maackii Regel) 3개 종과 중간인 서식지에서 기원한 까실쑥부쟁이 (A. ageratoides Turcz.) 1개 종의 침수조건에 대한 생육반응 비교로 서식지 환경이 내침수성 평가의 유효한 지표인지 알아보 고자 하였다. 실험대상 종을 6주간 무처리(대조구), 5일 침수처리, 7일 침수처리한 결과, 골등골나물과 새등골나물은 대조구와 처리구간 생육반응에서 유의한 차이가 관찰되지 않아 높은 수준 의 내침수성을 지니는 것으로 나타났다. 좀개미취는 생장반응이 처리구에서 대조구 대비 유의하게 감소하여 내침수성은 제한적 인 것으로 보였으나, 5일 침수처리구에서 광계 II의 최대양자효 율(Fv/Fm)이, 두 처리구 모두에서 지상부 대비 지하부의 비율 (R/S율)이 대조구와 유의한 차이를 보이지 않아 침수조건의 해 소 후 회복 가능성을 지니는 것으로 나타났다. 까실쑥부쟁이는 처리 4 주차에 모든 처리구에서 100%의 고사율을 보여 내침수 성을 갖추지 못한 것으로 판단되었다. 결론적으로, 서식지 환경 은 내침수성과 관련이 있다 할 수 있었으나, 내침수성의 정확한 평가를 위해서는 토양수분함량 외 다양한 환경요소들을 함께 고려해야할 필요성이 있을 것으로 보인다.

본 연구는 국내에서 실내 관상용으로 많이 활용되는 스킨답 서스의 실내재배 시 적정 인공광원, 수경재배 전기전도도 농 도 및 용토를 선발하기 위하여 수행하였다. 실내재배 시 인공 광원은 형광등, 적청 LED, 백색 LED로 처리하였다. 수경재배 시 양액 농도는 EC 1.2, 1.6, 2.0ds·m-1 수준으로 하였고, 재 배용토는 제올라이트, 코코피트, 펄라이트, 황토볼 4가지로 달리하였다. 스킨답서스의 실내 재배 시 줄기 길이는 형광등 과 적청 LED 처리보다 백색 LED 처리에서 길어졌다. 잎의 크기는 적청 LED 처리에서 형광등과 백색 LED 처리보다 커 지는 경향이었다. 엽록소 지수값은 백색 LED>적청 LED>형광 등 순으로 높았다. 수경재배 시 스킨답서스의 줄기길이는 EC 농도가 높아질수록 길어지는 경향이었고, 용토별로 비교하면 제올라이트와 코코피트에서 높은 경향이었다. 엽록소 지수값 도 EC 농도와 비례하여 높아졌고, 용토별로는 제올라이트와 코코피트에서 높았다. 스킨답서스의 생체중도 EC 농도가 높 을수록 높았고, 제올라이트와 코코피트에 높은 경향이었다. 상기 결과들을 종합할 때, 스킨답서스의 NFT를 이용한 실내 재배 시 적정 인공광원으로는 백색 LED를, 수경재배 양액의 농도는 EC 1.6∼2.0ds·m-1를, 그리고 NFT 용토는 제올라이 트나 코코피트가 적합하다는 것을 알 수 있었다.

To investigate the effect of the catalyst and metal–support interaction on the methane decomposition behavior and physical properties of the produced carbon, catalytic decomposition of methane (CDM) was studied using Ni/SiO2 catalysts with different metal–support interactions (synthesized based on the presence or absence of urea). During catalyst synthesis, the addition of urea led to uniform and stable precipitation of the Ni metal precursor on the SiO2 support to produce Ni-phyllosilicates that enhanced the metal–support interaction. The resulting catalyst upon reduction showed the formation of uniform Ni0 particles (< 10 nm) that were smaller than those of a catalyst prepared using a conventional impregnation method (~ 80 nm). The growth mechanisms of methane-decomposition-derived carbon nanotubes was base growth or tip growth according to the metal–support interaction of the catalysts synthesized with and without urea, respectively. As a result, the catalyst with Ni-phyllosilicates resulting from the addition of urea induced highly dispersed and strongly interacting Ni0 active sites and produced carbon nanotubes with a small and uniform diameter via the base-growth mechanism. Considering the results, such a Ni-phyllosilicate-based catalyst are expected to be suitable for industrial base grown carbon nanotube production and application since as-synthesized carbon nanotubes can be easily harvested and the catalyst can be regenerated without being consumed during carbon nanotube extraction process.

Intermuscular fat is essential for enhancing the flavor and texture of cultured meat. Mesenchymal stem cells derived from intermuscular adipose tissues are a source of intermuscular fat. Therefore, as a step towards developing a platform to derive intermuscular fat from mesenchymal stem cells (MSCs) for insertion between myofibrils in cultured beef, an advanced protocol of intermuscular adipose tissue dissociation effective to the isolation of MSCs from intermuscular adipose tissues was developed in cattle. To accomplish this, physical steps were added to the enzymatic dissociation of intermuscular adipose tissues, and the MSCs were established from primary cells dissociated with physical step-free and step-added enzymatic dissociation protocols. The application of a physical step (intensive shaking up) at 5 minutes intervals during enzymatic dissociation resulted in the greatest number of primary cells derived from intermuscular adipose tissues, showed effective formation of colony forming units-fibroblasts (CFU-Fs) from the retrieved primary cells, and generated MSCs with no increase in doubling time. Thus, this protocol will contribute to the stable supply of good quality adipose-derived mesenchymal stem cells (ADMSCs) as a fat source for the production of marbled cultured beef.

Doublesex and mab-3 related transcription factor (dmrt) play crucial roles in sex determination and sex differentiation in vertebrates and invertebrates. Although dmrt genes have been identified in vertebrates, little is known about aquatic invertebrates. In this study, two dmrt genes, namely, Dc_dmrt93B and Dc_dmrt99B, were identified from brackish water flea, Diaphanosoma celebensis. Transcriptional changes were observed in the dmrt genes when the flea was exposed to bisphenol (BP), an endocrine disruptor. Sequence and phylogenetic analyses showed that both dmrt genes contained two conserved domains, namely, DM and DMA, closely clustered with those of Daphnia spp. Additionally, a significant increase in the Dc_dmrt99B mRNA expression level was observed upon exposure to intermediate concentrations of BP (bisphenol A>bisphenol S=bisphenol F, p<0.05), while the expression of Dc_dmrt93B mRNA was slightly modulated. These findings imply that the two dmrt genes may be involved in sex differentiation of D. celebensis. Furthermore, it was found that the ability of BP to modulate dmrt genes could affect development and reproduction. This study provides a basis for understanding the function of the dmrt genes and the molecular mode of action of BP in small crustaceans.

Mesenchymal stem cells (MSCs) are capable of differentiating into mesenchymal tissue such as bone, cartilage, muscle, and adipose, and have been isolated and characterized from various species. Deer adipose tissue-derived MSCs (dAD-MSCs) have not been studied and deer bone marrow-derived MSCs (dBM-MSCs) have not been fully characterized. In this study, we firstly isolated MSCs from deer tissues and then compared characteristics of dAD-MSCs and dBM-MSCs. dAD-MSCs and dBM-MSCs exhibited significant increase in proliferation under low-glucose DMEM culture condition during 20 and 10 passages consecutive passages, respectively. Both cells expressed cell surface markers such as CD73, CD90, and CD105, but did not express CD34 and CD45. Two types of cells expressed stemness markers (Oct4, Sox2, and Nanog) and exhibited differentiation potential into mesodermal lineages. Both cells exhibited osteogenic and chondrogenic differentiation potential, but poor adipogenic differentiation potential. Specifically, dAD-MSCs have a greater capacity for chondrogenic differentiation potential compared to dBM-MSCs. Collectively, we successfully isolated dAD-MSCs from deer for the first time. This study suggests that adipose tissue of deer could be used as a source of deer MSCs.

The black pine bast scale are the main insects of the Japanese black pine forest in Korea, and the distribution is spreading around the Japanese black pine forest in the east and west coast. However, after the nationwide survey in 2010, there has been no investigation on the distribution and spread of these, so we conducted the 2017 and 2018 surveys to determine the extent of the northern area inland or east and west. In the 2017 survey, outbreaks were observed in 35 areas from 47 dong or myeon of 14 cities or counties, mainly in areas not previously located in the outbreak area. In the 2018 survey, additional outbreaks were confirmed at 14 out of 23 areas in the East Coast region, and damage was detected at 27 out of 28 points in the inland area of the South Sea and distribution was found at 16 out of 17 in the west coast.

Both Nilaparvata lugens Stål and Laodelphax striatellus Fallén has been known as the major rice pests which were irregularly migrated into Korea by wind current from China. We re-arranged and compared the resistance profiles to detect the existence convergent adaptation by using the previously published dataset (N. lugens at 2014, 17:711-716 and L. Striatellus at 2016, 19:247-252 in J. Asia Pac. Entomol., respectively). Both species commonly exhibited the high level of resistance to imidacloprids. Especially, the immigrant populations of L. Striatellus exhibited higher resistance level to indigenous populations, suggesting that they would settle down in Korea with insecticide resistance traits being predisposed. To detect the convergent adaptation to insecticide, pearson correlation analysis were employed by comparing mean dosage of LD50 and resistance ratio to nine insecticides. Strikingly, high and similar dosage responses were observed between the two species with high correlation coefficients of 0.928 (df=7, P <0.001) and 0.950 (df=7, P <0.001), respectively, in the comparison of LD50 vs. resistance ratio. This finding indicates that convergent adaption has occurred in both species through consistent selection by insecticides with similar usage patterns.

Entomopathogenic fungus is a useful control agent to sucking type insect such as whitefly and aphid. The fungi are influenced by some environmental factors such as relative humidity, temperature and UV and cause slow and fluctuation in pest control efficacy. Especially, UV kills conidia or spores of entomopathogenic fungi and a mycopesticide using fungi has short control period in field. UV intensity changes from season to season. Survival rate of entomopathognic fungi treated may differ from seasons and will show different control efficacy. Therefore, we conducted a study to estimate the persistence of an Isaria javanica isolate, which was already reported as sweet potato whitefly control agent, in potted greenhouse soil planted different crops. The number of survival spore decreased gradually and differ from seasons.
