Hair care products include shampoo, conditioner, treatment, hairstyling product, perm agent, coloring agent, and hair growing agent. The products other than shampoo and hair growing agent are used for scalp hair shaft, which is a dead part. Therefore, unlike skin care products, it is characteristic for hair care products that some of them act with a chemical reaction, like permanent wave lotions and oxidation hair dyes. In this article, I explain hair care products except in-bath products (shampoo, conditioner, and treatment) with a focus on their functions, product types, purposes, ingredients, and usages. Hairstyling can be performed by rearranging hydrogen bonds in hair. In other cases, hairstyles are made by fixing hair fibers with fixative ingredients. Hairstyling products assisting hairstyling or fixing hairstyles include hair sprays, hair water or lotions, hair foams, hair creams or milks, gels, liquids, tonics, oils, waxes, etc. The characteristics of their forms and components are explained. Perm agent is intended to change hair shape permanently by cleavage and recombination of disulfide bonds in the hair. In addition to the perm agent of quasi-drug from the past, there has been extending recently curling agents of the cosmetic category, of which curling mechanism is based on the reduction and oxidation of disulfide bonds, same as quasi-drugs. As for hair coloring agent, there are also quasi-drugs and cosmetic products. In the quasi-drug category, there are oxidation hair dyes and bleaching agents. There are semi-permanent hair color and temporary hair color in cosmetic products. Their coloring mechanisms and including components are described. As for hair growing agents, many effective ingredients have been proposed in accordance with the mechanism of thinning hair. I explain briefly products in the categories of medicine and quasi-drug.

Uniform temperature throughout a greenhouse is recommended, as the present climate control method and many other studies have shown that the temperature gradient decreases vertically and horizontally in a greenhouse. However, recent research revealed that roots, fruits, flowers, and shoot-tips are more sensitive to temperature changes than leaves and stems, indicating that uniform temperature control may not be necessary. In addition, energy-saving techniques that do not lead to yield loss are desirable to reduce energy costs and ensure sustainable greenhouse production. In this paper, we review current studies on local temperature control methods in greenhouse vegetable production, primarily focusing on the tomato, and compare them with novel climate-control techniques. Roots, fruits, shoot-tips and flowers are sensitive to temperature changes, showing negative symptoms under extreme temperature conditions. Therefore, the temperature of these plant organs should be controlled locally. Root zone temperature control enhances root growth and its associated physiological activities, promoting uptake of water and mineral nutrients. This subsequently leads to enhanced growth of shoots. Fruit temperature control may not be effective for tomato plants, but it promotes fruit growth and fruit sugar accumulation in melons and watermelons. Shoot-tip temperature control promotes the differentiation of leaf and flower buds. Flower temperature control enhances pollen viability and promotes fruit set. The combination of shoot-tip and flower heating enables low energy consumption compared with conventional heating, without loss of yield. Local temperature control techniques (except roots) have been studied in recent years; however, there is a distinct lack of research on the physiological mechanisms and practical approaches to develop a better local temperature control system. Thus, further studies are required on this area in the future.

To clarify the effect of ultrafine bubbles (UFBs) on the growth of tomato seedlings, we investigated elongation growth and dry matter production by analysing growth under different assimilation conditions and by modelling. The leaf area enlargement rate of plants grown with UFB nutrient solution increased and the specific leaf area (SLA) decreased at 18 days after sowing (DAS) relative to those grown without UFB solution. Thus, UFBs increased both leaf area and leaf thickness. UFB significantly increased the relative growth rate (RGR) and net assimilation rate (NAR) at 18 DAS, but there was no significant difference in SLA, RGR, and NAR between treatments at 25 DAS. These results were used to model plant growth with and without UFB treatment. In a second experiment, UFB treatment increased aboveground dry weight under a low-assimilation condition, but had no significant effect under a high-assimilation condition. Our model supported these results. It was also implied that UFB treatment affected leaf area expansion, but not dry matter production. Although the values predicted by the model were slightly lower than observed, it was possible to predict the effect of UFB treatment on plant growth with high accuracy.

As a major growth limitation, low temperature-induced injuries may adversely affect grape production in many areas. Ten-year-old grapevines ‘Thompson Seedless’ were sprayed with calcium chloride (CaCl2) three times at 10-day intervals from 19th September to 8th October 2015 and again in 2016 in a commercial vineyard. Bud samples were collected in December 2015 and 2016, January 2015 and 2016 and February 2016 and 2017. The buds were exposed to freezing treatments: −12, −16, −20, −24, and −28°C for 3 hours, to assess their low temperature tolerance. Moreover, the relationships among freezing tolerance and changes in antioxidant enzyme activity, soluble carbohydrates, proline and total proteins were investigated. Irrespective of foliar spray treatments, the freezing tolerance of buds increased from December to January and decreased in February. Application of CaCl2 at a 1% concentration resulted in increased bud freezing tolerance compared to the control plants. Application of 1% CaCl2 considerably increased the concentrations of soluble carbohydrates and total proteins in buds, but had subtle and inconsistent effects on proline. Activities of superoxide dismutase (SOD) and ascorbate peroxidase (APX) were increased in response to foliar application of CaCl2; however, inconsistent changes were found in the activities of catalase and peroxidase following CaCl2 application. The results showed that application of 1% CaCl2 increased freezing tolerance of grapevines predominantly via upregulating soluble carbohydrates and total proteins.

The purpose of the present study was to examine the relationships between three factors (physique, motor ability and intelligence quotient) of the 57 mentally retarded boys and girls from 8 to 17 years old in 1989. The physique factor was composed of standing height and body weight. The motor ability factor was composed of 50m dash run, standing broad jump and softball throw for distance. Their intelligence quotients were rated by Tanaka-Binet intelligence test. Their z-scores of physique and motor ability were computed by the means and standard deviations of physique and motor ability in the Japanese normal children.The following results were obtained.1) The mentally retarded boys and girls had significantly moderate correlation coeffients between z-scores of 50m dash run, standing broad jump, softball throw and intelligence quotients.2) There were no relationships between z-scores of physique and intelligence quotients in both sexes with the exception of body weight in girls. The mentally retarded girls had significantly negative correlation coefficient between body weight and intelligence quotients.3) There were no relationships between z-scores of standing height and motor ability in both sexes. The mentally retarded boys had significantly positive correlation coefficients between the z-scores of body weight and the z-scores of standing broad jump, softball throw.

A questionnaire concerning the putting on and taking off of clothes, socks and shoes of children with intellectual disabilities was given to their parents or guardians, mainly their mothers. The authors aimed to find ways of providing effective support through continual observation and case studies. The results of this study are as follows: (1) With regards to support, the surveyed children were classified into 5 groups according to the time they entered the school and the type of disability they had; (2) The parents or guardians have been able to teach their children to correctly identify the front or back of shirts, the top or bottom of socks and the difference between a left shoe and a right shoe; (3) Some visual effects were recognized in the case studies, namely the colored buttons on the bottom of a shirt, the colored heel or toe of socks and the colored elastic strings attached on the same side of shoes and the wrist; (4) The authors considered the necessity of developing effective support programs to help children with intellectual disabilities put on and take off clothes through joint studies and exchanges between specialists, teachers in charge of special classes for children with intellectual disabilities and clothing science scholars.

This paper presents a natural language processing tool, called CONV, which can translate Japanese sentences to well-formed formulas on an extended predicate logic, focusing on the knowledge representation scheme and the translating method to the scheme. This tool has been developed aiming to apply to several intelligent systems such as semantic information retrievers, dialogue systems and so on. In this tool, both a simple sentence and a complex sentence are represented by a single atomic formula, using ordinary words as predicate symbol and terms. Subordinate clauses in complex sentence are represented by embedded in the predicate or terms of the atomic formula for main clause, using the same form as main clause. Sentences are parsed using existent natural language processing tools and electronic dictionaries, and then are translated to logic formulas by newly developed rules.
