Black Ginseng
Black ginseng is a processed ginseng which prepared by  steaming and drying of white or red ginseng  for several times (usually 9). This process resulting in extensive changes in types and amounts of several secondary metabolites. Thus, primary ginsenosides (the main active inredients in ginseng) were transformed into less polar derivatives by steaming. In addition, apparent changes happened to other secondary metabolites such as the increasing  of phenolic compounds, reducing sugars and acidic polysaccharides as well as the decrease in concentrations of free amino acids and total polysaccharides. Furthermore, the presence of some Maillard reaction products like maltol was also engaged. These obvious chemical changes were associated with a noticeable superiority for black ginseng over white and red ginseng in most of the comparative biological studies including anticarcinogenic, immunomodulatory, anti-Inflammatory, antidiabetic, hepatoprotective, antioxidant and tonic effects.

Kangiten
Kangi-ten (Japanese: 歓喜天, "God of Bliss") is a god (deva or ten) in Shingon and Tendai schools of Japanese Buddhism. He is generally considered the Japanese Buddhist form of the Hindu god of wisdom, Ganesha and is sometimes also identified with the bodhisattva Avalokiteshvara. He is also known as Kanki-ten, Shō-ten (聖天, "sacred god" or "noble god"), Daishō-ten ("great noble god"), Daishō Kangi-ten (大聖歓喜天), Tenson (天尊, "venerable god"), Kangi Jizai-ten (歓喜自在天), Shōden-sama, Vinayaka-ten, Binayaka-ten (毘那夜迦天), Ganapatei (誐那缽底) and Zōbi-ten (象鼻天). Kangiten has many aspects and names, associated with Vajrayana (Esoteric Buddhist, Tantric, mantrayana) schools, Shingon being one of them. Although Kangiten is depicted with an elephant's head like Ganesha as a single male deity, his most popular aspect is the Dual(-bodied) Kangiten or the Embracing Kangiten depicted as an elephant-headed male-female human couple standing in an embrace.

Duchy
A duchy is a medieval country, territory, fief, or domain ruled by a duke or duchess, a high-ranking nobleman hierarchically second to the king or queen in European tradition. The term is used almost exclusively in Europe, where in the present day there is no sovereign duchy (i.e. with the status of a nation state) left. The term "duke" (like the corresponding "duchy") should not be confused with the title Grand Duke (or Grand Duchy, such as the present-day Grand Duchy of Luxembourg), as there exists a significant difference of rank between the two. In common European cultural heritage, a grand duke is the third highest monarchic rank, after emperor and king. Its synonym in many Slavic and Baltic European languages (Russian, Lithuanian, etc.) is translated as Grand Prince, whereas most Germanic and Romance European languages (English, French, Spanish, Italian etc.) use expressions corresponding to Grand Duke. Unlike a duke, the sovereign grand duke is considered royalty (or in German, 'royal nobility', Königsadel). The proper form of address for a grand duke is His Royal Highness (HRH), whereas for a non-royal duke in the United Kingdom it is His Grace. In contrast to this, the rank of a duke differs from one country to the next. In Germany, for example, a duke is listed in the aristocratic hierarchy below an emperor (Kaiser), king (König), grand duke (Großherzog), and elector (Kurfürst) – in that order – whereas in Britain the duke comes third after king/queen and prince (there are no British grand dukes or electors). In all countries, there existed an important difference between "sovereign dukes" and dukes subordinate to a king or emperor. Some historic duchies were sovereign in areas that would become part of nation-states only during the modern era, such as Germany (a federal empire) and Italy (a unified kingdom). In contrast, others were subordinate districts of those kingdoms that had unified either partially or completely during the medieval era, such as France, Spain, Sicily, Naples, and the Papal States. In England, the term is used in respect of non-territorial entities.

Smart Textile Materials
In the last three decades, the development of new kinds of textiles, so-called smart and interactive textiles, has continued unabated. Smart textile materials and their applications are set to drastically boom as the demand for these textiles have been increasing with the emergence of new fibers, new fabrics, and innovative processing technologies. Moreover, people are eagerly demanding washable, flexible, lightweight, and robust e-textiles. These features depend on the properties of the starting material, the post-treatment, and the integration techniques. In this work, a comprehensive review has been conducted on the integration techniques of conductive materials in and onto a textile structure. The review showed that an e-textile can be developed by applying a conductive component on the surface of a textile substrate via plating, printing, coating, and other surface techniques, or by producing a textile substrate from metals and inherently conductive polymers via the creation of fibers and construction of yarns and fabrics with these. In addition, conductive filament fibers or yarns can be also integrated into conventional textile substrates during the fabrication like braiding, weaving, and knitting or as a post-fabrication of the textile fabric via embroidering. Additionally, layer-by-layer 3D printing of the entire smart textile components is possible, and the concept of 4D could play a significant role in advancing the status of smart textiles to a new level.

Understanding Sexual Agency
Debates on human agency, not least female and sexual agency, have permeated the social scientific literature and health educational practice during multiple decades now. This article provides a review of recent agency debates, illustrating how criticisms of traditional conceptions of (sexual) agency have led to a notable diversification of the concept. We propose a comprehensive, inclusive description of sexual agency, focusing on the navigation of goals and desires in the wider structural context, and acknowledging the many forms sexual agency may take. We argue there is no simple relation between sexual agency and sexual health. We propose the following description: Sexual agency refers to a continuum of dynamic, everyday, situated modalities of action related to sexuality in which agents navigate (contrarieties between) personal goals, desires and preferences on the one, and personal living conditions, normative expectations and the wider structural context on the other hand. A diversity of internal (e.g. self-identification) and/or external goals (e.g. maintain social relationships or challenge the status quo) motivate and direct sexually agentic behavior. Sexual agency may aim for change as well as for endurance, continuity and stability. It may be overt or tacit. It varies with individual (e.g. temporal orientation) as well as situational variables (e.g. novelty). Sexual agency may reproduce but also resist and renegotiate (aspects of) prevailing norms and the status quo. There is no simple relation between sexual agency and sexual health or well-being. Modalities of action as well as the constructiveness of their (multiple) effects always depend on personal frames of reference as well as on the opportunities and restrictions provided by the (immediate and distant) personal and structural context, including moral and ideological frameworks and dominant sexual stories.

Shallow Affect
Reduced affect display, sometimes referred to as emotional blunting, is a condition of reduced emotional reactivity in an individual. It manifests as a failure to express feelings (affect display) either verbally or nonverbally, especially when talking about issues that would normally be expected to engage the emotions. Expressive gestures are rare and there is little animation in facial expression or vocal inflection. Reduced affect can be symptomatic of autism, schizophrenia, depression, posttraumatic stress disorder, depersonalization disorder, schizoid personality disorder or brain damage. It may also be a side effect of certain medications (e.g., antipsychotics and antidepressants). Reduced affect should be distinguished from apathy and anhedonia, which explicitly refer to a lack of emotion, whereas reduced affect is a lack of emotional expression (affect display) regardless of whether emotion (underlying affect) is actually reduced or not.

Interfaith Marriage
Interfaith marriage, sometimes called a "mixed marriage", is marriage between spouses professing different religions. Although interfaith marriages are most often contracted as civil marriages, in some instances they may be contracted as a religious marriage. This depends on religious doctrine of the two party's religions; some of which prohibit interfaith marriage, but others allow it in limited circumstances. Several major religions are mute on the issue, and still others allow it with requirements for ceremony and custom. For ethno-religious groups, resistance to interfaith marriage may be a form of self-segregation. In an interfaith marriage, each partner typically adheres to their own religion, but an important point is in what faith the children will be raised.
