RESUMO
OBJECTIVE: The purpose of this study was to compare current awareness of the "On a Code of Conduct for Scientists" (OCCS) among members of the Japanese Society for Hygiene (JSH). METHOD: An anonymous self-administered questionnaire was mailed to JSH members, including 439 councilors and 376 junior members (who were under 50 years of age with a membership of 3 years or longer, excluding councilors). Councilors were surveyed from November to December 2007, while junior members were surveyed from November to December 2008. RESULTS: The overall response rate was 40.6% (n = 331/815), with responses from 46.7% of the councilors (n = 205/439) and 33.5% of the junior members (n = 126/376). Among the respondents, 36.0% of councilors (n = 68) and 59.8% of junior members (n = 73) did not know the contents of "On the Code of Conduct for Scientists" (P < 0.01), while 76.3% of councilors (n = 145) and 61.4% of junior members (n = 75) had not heard of it (P < 0.05). However, a majority of the respondents reported interest in the Code [70.0% of councilors (n = 133), 68.6% of junior members (n = 83)] (P < 0.05) and a favorable attitude towards research ethics education [69.3% of councilors (n = 133), 68.9% of junior members (n = 84)] (P < 0.54). In addition, 24.3% of the responding councilors (n = 46) and 15.7% of the responding junior members (n = 19) believe it necessary for JSH to formulate its own code of conduct for scientists (P < 0.01). CONCLUSION: We clarified the current state of awareness of the OCCS among JSH members as well as the opinion of members for the JSH to have its own Code of Conduct for Scientists. This result provides important information that should be considered during the formulation of an individual code of conduct for scientists in the JSH.

OBJECTIVES: To investigate the impact of information on foodborne disease on consumers, we quantified consumers' anxiety, purchasing behaviors, and willingness-to-pay (WTP) in response to the reading of newspaper articles published in 2001 that documented the first cow in Japan to be infected with bovine spongiform encephalopathy (BSE). METHODS: An online questionnaire survey of 993 females aged 20-59 years was conducted in 2007. The participants were randomly selected from the general population via the Internet and were divided into three groups. Each group was assigned a different number of BSE-related articles to read, namely, two, four, and six articles, respectively. Each participant described her personal level of anxiety, underlying reasons for her anxiety, and changes in purchasing behavior after reading the articles. The respondents who wanted to buy guaranteed-safe beef were asked to state their maximal WTP. RESULTS: The level of anxiety was significantly lower and distrust of the relevant administration significantly greater in the group asked to read six articles than in the other groups. The WTP value for guaranteed beef was approximately 1.3-fold higher than the regular purchase price, with significant differences between groups. In the 'six-article' group, the ratio between WTP and the regular purchase price was significantly less than that in the 'four-article' group. CONCLUSIONS: These findings suggest that the anxiety of consumers can be reduced if they receive an appropriate amount of published information. WTP may be linked to the contents of the articles.
RESUMO
OBJECTIVES: The aim of this study was to clarify the attitudes towards the code of conduct for scientists among council members of the Japanese Society for Hygiene (JSH). We also aimed to collect information to be used as baseline data for future studies. METHODS: From November to December 2007, 439 Council members of the Japanese Society for Hygiene completed a self-administered questionnaire. RESULTS: The valid response rate was 43.7% (n=192/439). The mean ages of the subjects were 56.2 years for males (n=171), and 53.0 years for females (n=19). Many council members were unfamiliar with the "Code of Conduct for Scientists" established by the Science Council of Japan, suggesting that most of the regular members were also unfamiliar with these guidelines. However, the high level of interest in the "Code of Conduct for Scientists" established by the Science Council of Japan indicated a positive attitude towards learning about research ethics. Moreover, one-half of the subjects responded that JSH should establish a code of conduct for scientists. Below are some of the reasons for requiring JSH to establish a code of conduct: 1. Private information is prevalent in the field of hygiene. 2. The overall stance as an academic society would be established and would encourage individuality in academic societies. 3. Members have various backgrounds within the field of hygiene, and they should have a code of conduct different from that of their institution of affiliation. CONCLUSION: We clarified attitudes towards the Code of Conduct for Scientists among council members of the Japanese Society for Hygiene.

OBJECTIVES: The resignation rate of nurses working in hospitals is extremely high. This study aims to identify both the factors related to the resignation of nurses and the empowerment factors supporting their job retention. METHODS: In 2011 we conducted a Web-based questionnaire survey of nurses with less than 10 years of working experience. There were 25 survey items including the following reasons for choosing the current employment position, intention of continuing work, sense of fulfillment and the presence or absence of problems in the current workplace. In addition, nurses who previously had resigned were asked why they left their last workplace. RESULTS: The reasons why they chose the current workplace were markedly different between the not-resigned (A group) and previously resigned (B group) nurses. As a result of cluster analysis, the reasons for resignation were classified into six clusters; "overwork", "burnout", "bad atmosphere", "work life balance factors", "working conditions" and "marriage". CONCLUSIONS: In this study, it is shown that there is a positive correlation between the sense of fulfillment at work and the intention to do research work. It is suggested that encouragement of nurses to undertake research work is one of the empowerment factors supporting their job retention.

OBJECTIVE: Kathmandu tricycle taxi drivers, whose environmental lead (Pb) exposure is ascribable mainly to vehicular exhaust, were studied to examine a dose-response relationship between blood Pb (Pb-B) and serum erythropoietin (sEPO) concentrations. METHODS: Subjects were 27 drivers and 9 non-drivers. They were non-anemic healthy men with normal renal function. Pb-B was measured by an atomic absorption spectrometer with a graphite furnace, and sEPO was determined with a sandwich-type enzyme-linked immunosorbent assay. RESULTS: sEPO levels in drivers were lower than those of non-drivers, while Pb-B levels in drivers were higher than those of non-drivers. There was an inverse relationship between Pb-B and sEPO. CONCLUSIONS: The data suggest that Pb inhibits renal EPO production in a dose-dependent manner in persons with subclinical Pb toxicity. sEPO may serve as an early biochemical marker of subclinical Pb toxicity.

OBJECTIVE: The food consumption and serum nutritional status of people living in the Kathmandu valley, Nepal, were examined to obtain actual data for comparison with our previous findings. METHODS: A dietary survey of 45 males and 60 females was carried out in March 1997 by the 24-hr dietary recall method and nutrient intake was calculated from food tables of India and Japan. Fasting venous blood samples were obtained and serum biochemical parameters were measured using clinical kits. RESULTS: The mean body mass index values was at about the same level in both sexes, although the mean percentage body fat of females was higher than that of males, and vice versa for packed red cell volume. The main foods consumed by both sexes, were rice, potatoes, meats, milk & dairy products and vegetables, with a difference in the amounts consumed. Females did not drink alcoholic beverages. The mean daily intakes of energy, protein, lipids, iron and vitamin B group for the males were higher than those for the females, while those of vitamins A and C for the males were lower than those for the females. The mean values of serum biochemical parameters for both sexes were generally at the normal levels, but those of ALT and TG were at the higher end of the normal range. Differences of correlation between food groups and between serum parameters were observed depending on the sex, however, no clear relationship between food and nutrient intake and serum biochemical parameters were observed. CONCLUSIONS: The present food intake study revealed that the amounts of food consumption for both sexes, especially for the females, were mostly insufficient although the serum parameters were at the normal levels. The energy intake of both sexes was lower than that of estimated requirements and those in Terai region. The relatively high serum TG level of the subjects may be due to the consumption of large amounts of cereals containing much carbohydrate. Our findings suggested a marked influence on food consumption by food price and income in spite of the easier food availability in the city, and also lack of knowledge about nutrients and health, thus there is need for improvement of the nutritional status of this group of people.
RESUMO
Brief focal ischemia leading to temporary neurological deficits induces delayed hyperintensity on T1-weighted magnetic resonance imaging (MRI) in the striatum of humans and rats. The T1 hyperintensity may stem from biochemical alterations including manganese (Mn) accumulation after ischemia. To clarify the significance of this MRI modification, we investigated the changes in the dorsolateral striatum of rats from 4 hours through 16 weeks after a 15-minute period of middle cerebral artery occlusion (MCAO), for MRI changes, Mn concentration, neuronal number, reactivities of astrocytes and microglia/macrophages, mitochondrial Mn-superoxide dismutase (Mn-SOD), glutamine synthetase (GS), and amyloid precursor protein. The cognitive and behavioral studies were performed in patients and rats and compared with striatal T1 hyperintensity to show whether alteration in brain function correlated with MRI and histological changes. The T1-weighted MRI signal intensity of the dorsolateral striatum increased from 5 days to 4 weeks after 15-minute MCAO, and subsequently decreased until 16 weeks. The Mn concentration of the dorsolateral striatum increased after ischemia in concert with induction of Mn-SOD and GS in reactive astrocytes. The neuronal survival ratio in the dorsolateral striatum decreased significantly from 4 hours through 16 weeks, accompanied by extracellular amyloid precursor protein accumulation and chronic glial/inflammatory responses. The patients and rats with neuroradiological striatal degeneration had late-onset cognitive and/or behavioral declines after brief focal ischemia. This study suggests that (1) the hyperintensity on T1-weighted MRI after mild ischemia may involve tissue Mn accumulation accompanied by Mn-SOD and GS induction in reactive astrocytes, (2) the MRI changes correspond to striatal neurodegeneration with a chronic inflammatory response and signs of oxidative stress, and (3) the subjects with these MRI changes are at risk for showing a late impairment of brain function even though the transient ischemia is followed by total neurological recovery.
