In the $21^{st}$ century, technology is a tool for the expansion of the five senses and physical ability that works as an element for posthuman identity. This study analyzes and theorizes on the characteristics of the posthuman body in fashion illustration. The method of this study analyzes documentaries about posthuman and fashion illustration. The results are as follow. Posthuman body types are classed as hybrid body, plastic surgery body, and digital body. The characteristics of the posthuman body are categorized as ultra- functional prosthetic, mythical undifferentiated, radical plastic surgery type and post-physical digitization type. The ultra-functional prosthetic type shows a restored body and upgraded functional body through a machine hybrid, cyborg suit and mannequin hybrid. It is a break from classical gender identity to form a nerve sense extension that displays physical and abstract power. The mythical undifferentiated type shows a therianthropic form, parts of an animal body, radical skin and gender bending. It represents the return to an undifferentiated world, the desire of a powerful being and the possibility of radical transformation. The radical plastic surgery type shows a photomontage of an ideal body, transgendered body, grotesque body marking, absence of partial or overall face organ and the expansion of abnormal body organs. It represents the expression of narcissism, unconscious desire, fantasy, fear and suggests an alternative ideality, sexual attachment and ambiguous gender identity. The post-physical digitization type shows an imperfect form or duplicated ego image through the omission of the body silhouette or detailed form, fragmented image using net, representative self like optical illusion using typography, an imperfect vague silhouette and immaterial body outline through the use of virtual light. It represents the lack of desire, narcissism, fluidity in a virtual space, the continued creation of a new self, ambiguous gender identity and the liberation of environment, sex, and race. Likewise, the posthuman in fashion illustration shows the absence of a species boundary, destruction of classical gender identity, a new personality and virtual self image.

Near-rings considered are right near-rings and R is a near-ring. $J_0^r(R)$, the right Jacobson radical of R of type-0, was introduced and studied by the present authors. In this paper $J_1^r(R)$ and $J_2^r(R)$, the right Jacobson radicals of R of type-1 and type-2 are introduced. It is proved that both $J_1^r$ and $J_2^r$ are radicals for near-rings and $J_0^r(R){\subseteq}J_1^r(R){\subseteq}J_2^r(R)$. Unlike the left Jacobson radical classes, the right Jacobson radical class of type-2 contains $M_0(G)$ for many of the finite groups G. Depending on the structure of G, $M_0(G)$ belongs to different right Jacobson radical classes of near-rings. Also unlike left Jacobson-type radicals, the constant part of R is contained in every right 1-modular (2-modular) right ideal of R. For any family of near-rings $R_i$, $i{\in}I$, $J_{\nu}^r({\oplus}_{i{\in}I}R_i)={\oplus}_{i{\in}I}J_{\nu}^r(R_i)$, ${\nu}{\in}\{1,2\}$. Moreover, under certain conditions, for an invariant subnear-ring S of a d.g. near-ring R it is shown that $J_2^r(S)=S{\cap}J_2^r(R)$.

The purpose of this paper is to introduce a new class of rings containing the class of m-formally Noetherian rings and contained in the class of nonnil-SFT rings introduced and investigated by Benhissi and Dabbabi in 2023 [4]. Let A be a commutative ring with a unit. The ring A is said to be nonnil-m-formally Noetherian, where m ≥ 1 is an integer, if for each increasing sequence of nonnil ideals (I_n)_n≥0 of A the (increasing) sequence (∑_i1+⋯+im=nI_i1I_i2⋯I_im)_n≥0 is stationnary. We investigate the nonnil-m-formally Noetherian variant of some well known theorems on Noetherian and m-formally Noetherian rings. Also we study the transfer of this property to the trivial extension and the amalgamation algebra along an ideal. Among other results, it is shown that A is a nonnil-m-formally Noetherian ring if and only if the m-power of each nonnil radical ideal is finitely generated. Also, we prove that a flat overring of a nonnil-m-formally Noetherian ring is a nonnil-m-formally Noetherian. In addition, several characterizations are given. We establish some other results concerning m-formally Noetherian rings.

Paint Spray is developed as a direct sampling ionisation method for mass spectrometric analysis of additives in polymer-based surface coatings. The technique simply involves applying an external high voltage (5 kV) to the wetted sample placed in front of the mass spectrometer inlet and represents a much simpler ionisation technique compared to those currently available. The capabilities of Paint Spray are demonstrated herein with the detection of four commercially available hindered amine light stabilisers; TINUVIN${(R)}$770, TINUVIN${(R)}$292, TINUVIN${(R)}$123 and TINUVIN${(R)}$152 directly from thermoset polyester-based coil coatings. Paint Spray requires no sample preparation or pre-treatment and combined with its simplicity requiring no specialised equipment makes it ideal for use by non-specialists. The application of Paint Spray for industrial use has significant potential as sample collection from a coil coating production line and Paint Spray ionisation could enable fast quality control screening at high sensitivity.

Let M and N be modules over a ring R. The purpose of this paper is to study modules M, N for which the bi-module [M, N] is regular or pi. It is proved that the bi-module [M, N] is regular if and only if a module N is semi M-projective and $Im({\alpha}){\subseteq}^{\oplus}N$ for all ${\alpha}{\in}[M,N]$, if and only if a module M is semi N-injective and $Ker({\alpha}){\subseteq}^{\oplus}N$ for all ${\alpha}{\in}[M,N]$. Also, it is proved that the bi-module [M, N] is pi if and only if a module N is direct M-projective and for any ${\alpha}{\in}[M,N]$ there exists ${\beta}{\in}[M,N]$ such that $Im({\alpha}{\beta}){\subseteq}^{\oplus}N$, if and only if a module M is direct N-injective and for any ${\alpha}{\in}[M,N]$ there exists ${\beta}{\in}[M,N]$ such that $Ker({\beta}{\alpha}){\subseteq}^{\oplus}M$. The relationship between the Jacobson radical and the (co)singular ideal of [M, N] is described.

본 연구는 청나래고사리 성엽 추출물의 항산화물질의 함량과 항산화능을 향상시킬 수 있는 효과적인 추출방법을 개발하기 위하여 시행하였다. 동결건조한 청나래고사리 성엽의 분쇄시료 1 g을 메탄올, 80% 에탄올 및 물 등 3가지 용매와 섞은 후 6시간 동안 상온 침지, $60^{\circ}C$ 가열 및 200 rpm에서 교반하여 추출하거나 42 kHz의 초음파 수조에서 15, 30, 45분 동안 추출하였다. 추출물은 여과한 다음 가용성고형분, 총 폴리페놀 및 총 플라보노이드의 함량을 측정하였으며, 항산화활성은 DPPH와 ABTS radical 소거활성을 $RC_{50}$으로 환산하여 측정하였다. 80% 에탄올을 용매로 하여 30분 동안 초음파추출 하였을 때 가용성고형분(0.317 $g{\cdot}g^{-1}$ db), 총 폴리페놀(70.90 $mg{\cdot}g^{-1}$ db) 및 총 플라보노이드(41.53 $mg{\cdot}g^{-1}$ db)의 추출수율이 가장 우수하였으며, DPPH와 ABTS radical 소거활성 또한 가장 우수하였다(각 $RC_{50}$=0.14 $mg{\cdot}ml^{-1}$와 0.09 $mg{\cdot}ml^{-1}$). 상기의 연구결과에 따라 청나래고사리의 성엽은 천연항산화소재로 활용가능하며, 80% 에탄올을 용매로 15-30분 동안 초음파추출하는 것이 추출물의 항산화효과를 증가시키며 추출에 소요되는 시간을 줄일 수 있는 효과적인 추출방법으로 생각되었다.

The move from steel tubes to bent wood and the 'laboratory experiments' with wood which Aalto carried out in order to create furniture gave him vital impulses as he sought and found his own architecture style in the 1930s. Like his architecture Aalto's chair designs represent a 'humanized' interpretation of the severe aesthetic and radical technological experimentation of the Modern Movement. The purpose of this study is to find what is the result of the form of his works on the basis of main idea and tend of his works, to search the element and principle of formal composition, to establish the relation-ship between the architect's philosophy and the form of his works. Aalto's furniture, constructed of laminate bent wood or moulded plywood, is not only functionalistic, but also ideal for the psychological need of the people, which is the special quality that complements the Factionalism that features mostly on the metal tube furniture. It shows that Aalto is a humanist dealing with mechanized age.

Let R be a 2-torsion free prime ring with center Z, U be the Utumi quotient ring, Q be the Martindale quotient ring of R, d be a derivation of R and L be a Lie ideal of R. If $d(uv)^n=d(u)^md(v)^l$ or $d(uv)^n=d(v)^ld(u)^m$ for all $u,v{\in}L$, where m, n, l are xed positive integers, then $L{\subseteq}Z$. We also examine the case when R is a semiprime ring. Finally, as an application we apply our result to the continuous derivations on non-commutative Banach algebras. This result simultaneously generalizes a number of results in the literature.

This study examined the quality characteristics of cookies comprised of various amounts of barley-sprout powder by analyzing the physico-chemical characteristics of the cookies and investigating a sensory evaluation. For the study, the cookies were cooked with the following levels of barley-sprout powder: 0%, 3%, 6%, 9%, and 12%. The results show that the moisture content of the cookies was increased in accordance with the level of barley-sprout powder and this result is the same as the spreadability factor of the cookies (p<0.001). Also, the pH and brix values of the samples decreased in accordance with the level of barley-sprout powder (p<0.001). Regarding hunter's colors, the values of L (lightness), a (redness), and b (yellowness) are significantly decreased, increasing the quantity of barley-sprout powder (p<0.001). For the textural characteristics, the results show that the hardness of the cookies decreased in accordance with the addition of the barley-sprout powder; furthermore, the results indicate a tendency whereby the DPPH-radical-scavenging activity and the total polyphenol content of the cookies were increased, thereby increasing the quantity of the barley-sprout powder (p<0.001). For the sensory evaluation, the cookies that were made with 6 % barley-sprout powder received the highest scores in terms of appearance, taste, and overall preference (p<0.05, p<0.001). This study suggests that barley-sprout powder is an excellent ingredient for improving the acceptability and functionality of cookies, and that, in relation to the flour quantity the ideal proportion of barley-sprout powder is 6%.
