Promotion of brand-related sustainability initiatives (BSI) is a modern managerial issue, as BSI seems to impact not only sustainability but also consumer psychology toward a brand. In this regard, the author has extended self-congruity theory and suggested the concept of brand-sustainability-self-congruence (BSSC) as the image congruence of the triad comprising brand, BSI, and self-concept. Former surveys report predictive effects of BSSC on consumers’ brand evaluation, leading to increased brand equity (Kumagai, 2022, 2023).

Adaptive Responses to Electrophilic Stress and Reactive Sulfur Species as their Regulator Molecules
Kumagai, Yoshito,Akiyama, Masahiro,Unoki, Takamitsu Korean Society of ToxicologyKorea Environmental Mu 2019 Toxicological Research Vol.35 No.4
We are exposed to numerous xenobiotic electrophiles on a daily basis through the environment, lifestyle, and dietary habits. Although such reactive species have been associated with detrimental effects, recent accumulated evidence indicates that xenobiotic electrophiles appear to act as signaling molecules. In this review, we introduce our findings on 1) activation of various redox signaling pathways involved in cell proliferation, detoxification/excretion of electrophiles, quality control of cellular proteins, and cell survival during exposure to xenobiotic electrophiles at low concentrations through covalent modification of thiol groups in sensor proteins, and 2) negative regulation of reactive sulfur species (RSS) in the modulation of redox signaling and toxicity caused by xenobiotic electrophiles.

The nutritional status of trace minerals in cattle of Java in Indonesia was investigated by evaluating Cu, Fe, Mo, Zn and Mn concentrations in diets and livers, and Cu and Zn concentrations in blood plasma. Investigations were conducted on Jonggol (West Java), Malang (East Java) and Mojokerto (East Java) in both the rainy and the dry seasons in 1988. In Jonggol, low Cu concentrations in diets showing 7.1 mg/kg in the rainy season and 10.9 mg/kg in the dry season were observed and all plasma samples showed Cu concentrations below the critical level ($0.65{\mu}g/ml$). Thirty percent of the liver samples in Malang and 54% of those in Mojokerto showed lower Cu concentrations than the critical level (75 mg/kg on a dry matter basis). Fe concentrations in diets from the three regions showed a wide variation of values ranging from 249 to 30,000 mg/kg. A large amount of Fe was accumulated in livers from Malang and Mojokerto, giving average concentrations of 498 mg/kg. Zn concentration in diet and plasma samples were close to the borderline and some Zn concentration in these samples showed deficient levels. Mo and Mn concentrations in diets and livers showed normal levels.

The study examines consumers’ brand evaluation when a sustainable polyester based on new bottle recycling technology is used in the fashion sector. Additionally, the study assesses the luxury value priorly perceived from a brand and its effect on con- sumers’ brand evaluations based on this sustainable development type. According to 440 samples collected in Japan, structural equa- tion modeling reveals that the use of sustainable polyester increases perceived quality risk toward a product. The data also show that perceived luxury brand value complementarily reduces this risk perception and increases brand trust, thereby contributing to consumers’ brand attitude and purchase intention. Additionally, these effects of perceived luxury value on brand trust and perceived risk are found even in the case of low-luxury brands. According to the data, by building/enhancing luxury brand attributes prior to launching sustainable projects, companies are likely to increase the desirable consumers’ brand evaluation based on brand-related sustainable development thereafter. The results imply that luxury firms can play a leading role in sustainable development because their brand attributes inhibit consumers’ risk perceptions of this new industrial product. Meanwhile, the data imply that companies cannot instantly increase brand trust through the launch of sustain- able products, although environmental sustainability is socially desirable.

Fecal microbiota transplantation (FMT) is a treatment designed to correct gut dysbiosis by administration of feces from a healthy volunteer. It is still unclear whether FMT for children with ulcerative colitis (UC) is effective or hazardous. Here we describe a young patient to have received FMT for UC. A three-year-old girl was admitted to our hospital with severe active UC, and treated with aminosalicylates and various immunosuppressive drugs. As remission was not achieved, we decided to try FMT before colectomy. We administered donor fecal material a total of six times by retention enema (${\times}2$) and via a nasoduodenal tube (${\times}4$) within 10 days. The patient developed abdominal pain and pyrexia after each FMT session. Analyses revealed the transferred donor fecal microbiota had not been retained by the patient, who ultimately underwent colectomy. The severity of the UC and/or timing of FMT may have partly accounted for the poor outcome.
A STUDY ON THE MINERAL STATUS OF BEEF AND DAIRY CATTLE AND BUFFALO IN CENTRAL THAILAND
Kumagai, H.,Swasdiphanich, S.,Prucsasri, P.,Yimmongkol, S.,Rengsirikul, B.,Thammageeratiwong, P. Asian Australasian Association of Animal Productio 1996 Animal Bioscience Vol.9 No.5
Nutritional status of minerals of beef and dairy cattle and buffalo in central Thailand were investigated by evaluating the mineral concentrations in feedstuff and blood plasma of animals. Three crossbred beef cow herds, a native cow herd, a buffalo female herd and 3 dairy cattle herds which consisted of the herds of lactating cows, dry cows and heifers were studied in both rainy and hot seasons. Low Na concentrations (<0.07% on a dry matter basis) in pasture samples from the fields for a cross bred beef cow were observed. Copper concentrations in all the pasture samples ranged from 3.7 to 13.5 mg/kg. Iron and Se concentration in pasture samples had a wide variety ranging from 185 to 1,345 and 0.033 to 1.127 mg/kg, respectively. The concentrations of K, Ca, Mg, P, Zn and Mn in total diets were higher than the requirements for beef and dairy cattle. Some animals with subnormal plasma Cu concentrations(< $0.65{\mu}g/ml$) existed in each herd. The animals which showed subnormal plasma Se concentrations(< $0.03{\mu}g/ml$) were observed in beef cow herds. The concentrations of Ca, Mg and Zn in plasma of animals were normal. Attention should be paid to the deficiencies in Na, Cu and Se of the animals in central Thailand.
A STUDY ON NUTRITIONAL STATUS OF MACRO MINERALS OF CATTLE IN JAVA IN INDONESIA

Nutritional status of cattle in Java in Indonesia was investigated by evaluating P, Ca, Mg, K and Na concentrations in forage and plasma inorganic phosphorus (Pi), Ca and Mg, hematocrit and hemoglobin concentrations of cattle during both rainy and dry seasons in 1988. Investigations were conducted at Jonggol (West Java), Malang (East Java) and Majokerto (East Java). Low P content in forage averaging 0.11% on a dry matter basis, high Ca:P ratio in forage in the rainy season (7.7:1) and low plasma Pi concentrations averaging 4.71 mg/dl were observed in Jonggol. In all three places, Ca content in forages was higher than the requirement according to the NRC standard and plasma Ca concentrations were above the critical level. During the rainy season forty percent of cattle in Malang and Mahokerto showed plasma Mg concentrations below 2mg/dl in spite of normal Mg and K content in forage. Forage samples from each place showed a wide variety in Na content, and Na content of two thirds of forage samples was lower than the requirement according to the NRC standard. Hematocrit and hemoglobin concentrations in Malang and Majokerto showed higher values than the normal range.
Layered $LiCo_{x}Mn_{1-x}O_2$ as Cathode Materials for Li-Ion Batteries
Kumagai, Naoaki,Myung, Seung-Taek,Komaba, Shinichi The Korean Institute of Electrical and Electronic 2001 전기전자재료 Vol.14 No.12
Orthorhombic type LiCo$_{x}$Mn$_{1-x}$ O$_2$(0$\leq$x$\leq$0.14) oxides have been synthesized by hydrothermal treatment of (Co$_{x}$Mn$_{1-x}$ )$_3$O$_4$precursors and LiOH aqueous solution at 17$0^{\circ}C$. As-synthesized powders showed well-ordered $\beta$-MaMnO$_2$structures, and the products were single crystalline particle oxides from TEM observations. The particle size decreased with increasing the amount of Co substituent. Much more improved capacity upon 100 cyclings was clearly seen in orthorhombic LiCo$_{0.1}$Mn$_{0.9}$O$_2$, comparing to orthorhombic LiMnO$_2$..EX>.
