Peres, Marize Terezinha Lopes Pereira;Mapeli, Ana Maria;Faccenda, Odival;Gomes, Alcir Teixeira;Honda, Neli Kika;
Brazilian Archives of Biology and Technology , 2009, DOI: 10.1590/S1516-89132009000400027
Abstract: environmental degradation caused by the excessive use of pesticides has motivated studies aimed at the discovery of new formulations for pest control. the bioassays carried out under laboratory conditions for the present study involved the germination and seedling growth of lactuca sativa cv. grand rapids and allium cepa cv. baia periforme treated with lecanoric acid or one of seven esters obtained from the alcoholysis of the acid. each substance was tested at concentrations of 10-3, 10-5, 10-7 m, and 10-9 m. the results revealed that, except for lecanoric acid and methyl orsellinate, all other compounds exhibited significant differences in their action when compared with the controls. also, a. cepa was more sensitive to the compounds assayed, at the concentrations tested. nearly all the esters exhibited significant effects, a feature that could makes them promising for the development of new natural herbicides.

Gomes, Alcir Teixeira;Smania Júnior, Artur;Seidel, Cintia;Smania, Elza de Fátima Albino;Honda, Neli Kika;Roese, Fernanda Mesquita;Muzzi, Rozanna Marques;
Brazilian Journal of Microbiology , 2003, DOI: 10.1590/S1517-83822003000300002
Abstract: in order to obtain new compounds with antibacterial activity, the derivatives 2,4-dihydroxy-6-methylbenzoic acid (orsellinic acid) and 2,4-dihydroxy-6-methylbenzoates (orsellinates) were obtained through alcoholyses of lecanoric acid. all these substances were tested against gram-positive and gram-negative bacteria by a microdilution method. staphylococcus aureus, xanthomonas campestris var. vesicatoria and ralstonia solanacearum were most sensitive to n-propyl 2,4-dihydroxy-6-methylbenzoate, n-pentyl 2,4-dihydroxy-6-methylbenzoate and n-hexyl 2,4-dihydroxy-6-methylbenzoate with mic (minimal inhibitory concentration) values ranging from 62.5 to 7.8 μg×ml1. these results showed that homologation in carbon chain may lead to compounds with more pronunced activities.

Acta Scientiarum : Technology , 2006,
Abstract: Neste trabalho avaliou-se o desempenho de um microtrator equipado com três diferentes tipos de acionamento. Um mesmo chassi de um microtrator foi instalado, alternadamente, com um motor elétrico trifásico (MCA), um motor elétrico de corrente contínua (MCC) e com um motor de combust o interna (MCI). Os ensaios do microtrator com cada um dos motores permitiram a determina o da for a de tra o máxima, da velocidade de deslocamento, do consumo de combustível e a patinagem dos rodados. O MCC desenvolveu maior for a de tra o, sendo 22% superior aos demais. O consumo específico de energia para os microtratores decresceu com o aumento da patinagem. This study evaluated the performance of a microtractor implemented in three different operational types. A microtractor chassis was alternately operated with a three-phase electric engine (MCA), a direct-current electric engine (MCC) and an internal combustion engine (MCI). The rehearsals of the microtractor implemented in each one of the engines allowed determinations of the maximum tractive force, the forward speed and the fuel consumption in wheel skiddings. The MCC developed greater snatch force, being 22% superior to the others. The specific consumption on energy for the microtractors decreased as the skiddings increased.
Empirical Analysis for High Quality Software Development  [PDF]

Abstract: It remains important for a development organization to configure a software process that enables it to develop software products with the least possible number of defects after shipment. A development organization of CMMI level 5 has, over three years, been strived to improve those software projects that had been noted as having many defects after shipment. In this paper, we discuss our organization’s improvement (Kaizen) activities, to analyze the important matters of software process to be considered when developing a software product with the least possible number of defects after shipment. Our results are identified by three important points; 1) early ensured quality by defect detection during design or code review; 2) quality assurance for both process quality and product one; and 3) quantitative management by which data of the appropriate resolution can be collected at an appropriate timing.
Concept Development and Implementation of Family Care/Caring Theory in Concentric Sphere Family Environment Theory  [PDF]
Naohiro Hohashi, Junko Honda
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.59078
Abstract: Caring is directed toward a variety of things. One of them is thought to be the concept of “family caring” aimed at families. This study attempts to clarify family caring and develop Family Care/ Caring Theory (FCCT), with the aim of implementing it in conjunction with an existing family nursing theory, the Concentric Sphere Family Environment Theory (CSFET). In Japan and in Hong Kong, family ethnography (including formal interviews) was conducted. As a result, the item “family health care nurses and their colleagues” was added to the family external environment of the CSFET. In the family environment, evidence was obtained to the effect that the family system unit is cared for by the nursing professional, and conversely the family system unit cares for the nursing professional, in a circular transaction. Observing the two-dimensional plane formed by the structural distance and functional distance, family caring assumes a structure of concentric circles, and according to transactions, the structural distance and functional distance between the nursing professional and family system unit are gradually approached, and through deepening of mutual trust maintain an appropriate distance. Moreover observing the three-dimensional space-time continuum which is created through addition of the temporal distance, family caring forms a helical structure. As transactions are repeated along the temporal axis, the family system unit’s self-actualization of other individuals and the self-actualization of the nursing professional are realized. Through these processes, a family care/caring relationship is reinforced and established. This is the concept of FCCT. Through future utilization in clinical settings this will be empirically substantiated, and it will be necessary to continue making creative corrections and revisions.

Abstract: In the neck meridian test, the examinee stretches his or her neck in four directions and rates the intensity of pain and/or symptoms on a four point Likert scale. The four responses are summed to calculate the test score. This study conducted secondary analyses of data from a randomized controlled trial of self-administered acupressure. The study aimed to examine the change of the neck meridian test score induced by self-administered acupressure. The data of 54 (male, n = 34; female, n = 20) students, who were randomly assigned to an intervention group (IG) and a control group (CG), were subjected to secondary analyses. The IG participants were asked to complete a self-administered acupressure intervention for two weeks; the CG participants were not. In the IG, the perceived stress decreased significantly over time, while the neck meridian test score decreased significantly; in contrast, this score increased in the CG. A significant positive correlation was found between the changes in the perceived stress and neck meridian test scores. These results supported validity of the neck meridian test as a tool for assessing perceived stress.

Abstract: in the current view of globalized industrialization, it has become fundamental to manage essential costs effectively. conventional programs for reducing costs, do no consider the value agregation grade of routine activities because of the distortion of current accounting systems. this study, presents the main reasons for the lack of relevance of the cost information, commenting on the problem of the reduction of forest waste and its consequences. using a case study in a company from the forest sector, a simulation of activity based costing (abc) is demonstrated in a determined area of the company it is concluded that the adoption of a more refined cost system, such as the abc, should be included in programs, that seek to increase the competitiveness of the forest sector.
O conceito freudiano de puls?o (Trieb) e algumas de suas implica??es epistemológicas
Honda, Helio;
Fractal : Revista de Psicologia , 2011, DOI: 10.1590/S1984-02922011000200012
Abstract: the article analyzes the concept of instinct [trieb] and discusses some of the epistemological implications to the status of psychoanalysis. such implications would be directly related to 1) the demarcation of a field of study, the psychoanalytic field itself, 2) the nature of the phenomena that inhabit the land so marked, and which therefore has to do 3) with the epistemological status of psychoanalysis as a scientific and autonomous discipline, including independent of other psychologies. the analysis is focused on the meaning of the instinct as a psychical representative of the stimuli that comes from inside the body, in order to highlight the main erogenous nature of psychic reality.
