エッジ抽出は,画像処理における特徴抽出処理の手法として,根本的かつ重要な問題である.一般にエッジ抽出法では,雑音除去,勾配強度計算,エッジの追跡などのアルゴリズムを段階的に適用することによって高精度な処理を実現してきた.しかし,それぞれのアルゴリズムには種々のパラメータが存在し,それらのパラメータ値は一般に入力画像を参照して対話的に決定されているため,適切なパラメータ値の決定は困難である.本研究では輝度画像を対象として,雑音の抑止と勾配強度計算をともに行うことが可能な回帰面を利用した新しいエッジ抽出法を提案する.提案手法では,エッジ抽出結果を制御するパラメータは非エッジの割合を示す一つであり,簡易に設定が可能である.基本図形と自然画像を用いた実験の結果,固定したパラメータ値を用いた提案手法は,適応的にパラメータを設定したCannyオペレータより高精度なエッジ抽出を実現できることを確認した.

Background: The counterfactual definition of confounding is often explained in the context of exchangeability between the exposed and unexposed groups. One recent approach is to examine whether the measures of association (e.g., associational risk difference) are exchangeable when exposure status is flipped in the population of interest. We discuss the meaning and utility of this approach, showing their relationships with the concept of confounding in the counterfactual framework.Methods: Three hypothetical cohort studies are used, in which the target population is the total population. After providing an overview of the notions of confounding in distribution and in measure, we discuss the approach from the perspective of exchangeability of measures of association (e.g., factual associational risk difference vs. counterfactual associational risk difference).Results: In general, if the measures of association are non-exchangeable when exposure status is flipped, confounding in distribution is always present, although confounding in measure may or may not be present. Even if the measures of association are exchangeable when exposure status is flipped, there could be confounding both in distribution and in measure. When we use risk difference or risk ratio as a measure of interest and the exposure prevalence in the population is 0.5, testing the exchangeability of measures of association is equivalent to testing the absence of confounding in the corresponding measures.Conclusions: The approach based on exchangeability of measures of association essentially does not provide a definition of confounding in the counterfactual framework. Subtly differing notions of confounding should be distinguished carefully.

This paper deals with the measured data obtained through the at-sea measurement of the TLP “EHIME”, an offshore nursery pilot firm station of Marino-Forum 21, of which tendons are parallel wire strands (PWS) protected by polyethylen sheath with specially manufactured cushion rubber rings at each ends and connected to a gravity type template through a belimouth shape structure. The measured data of the TLP dynamic responses are compared with theoretical estimation, and the strength performance of PWS as TLP tendons are discussed.The main results are as follows; 1) the TLP with the PWS mooring system has the same dynamic response characteristics as the conventional TLP with the steel pipe mooring system, 2) the mooring system by use of PWS type tendons adopted for the TLP “EHIME” exhibits sufficient strength and durability characteristics.

C-C chemokine receptor 7 (CCR7) contributes to cell homing to lymph nodes (LNs). Recent studies reported that CCR7 is also expressed in tumor cells, which correlates with LN metastasis in various cancers. However, the expression of CCR7 in tumor cells is unknown in dogs due to the lack of appropriate antibodies. In the present study, a fusion protein of C-C chemokine ligand 19 (CCL19) was employed as an alternative method to CCR7 antibodies. The fusion CCL19 protein specifically detected CCR7 expressed in canine lymphoma cell lines, which showed active chemotaxis to both canine and mouse ligands. The present study will help further research on the involvement of canine CCR7 in LN metastasis.

Indoor radon and thoron concentration measurements have been intensively carried out since the 1980s for assessment of radiation doses to workers and the general public. For example, the European Union countries established reference levels for indoor radon concentration in relation to national action plans to address long-term risk from radon exposures. Measurements done using a reliable method are the only way to investigate radon concentration levels. In order to ensure the quality of measurements, intercomparisons among laboratories are performed, as one verification method. The primary purpose of this paper is to provide a concise review of intercomparisons of radon and thoron monitors carried out by four institutions: NIRS (Japan), PHE (UK), BfS (Germany) and SURO (Czech Republic). The different measurement set-ups, evaluation methods and statistical treatments utilized by those institutions are described.

This paper describes the analysis of amino acid sequence as well as the denaturation experiment of soluble globular and membrane proteins. The two kinds of proteins were discriminated by amino acid sequence almost completely, using only the hydrophobicity. The denaturation measurements lead to the conclusion that the hydrophobic interaction determines the form of proteins (i.e. globular or membrane proteins), while the polar interactions play major role in the tertiary structure formation.

Medium-chain triglycerides (MCT) are useful for increasing fat utilization during exercise. The highest rate of fat oxidation during submaximal exercise tends to precede the lactate threshold in untrained adults. In our previous study, blood lactate concentration was more than 4 mmol/L (onset of blood lactate) in recreational athletes during exercise at a workload corresponding to 60% peak O2 uptake (V・o2), which was below ventilation threshold. In the present study, we investigated the effect of 2 week of ingestion of food containing 6 g MCT on substrate oxidation during moderate-intensity (50% peak V・o2) exercise and high-intensity (70% peak V・o2) exercise in recreational athletes. For comparison, two experimental trials were conducted after participants had been administered isoenergic test foods (MCT-supplemented food with mainly maltodextrin-containing carbohydrate (MCT + CHO) or CHO) for 2 weeks, with a washout period between trials. Participants were instructed to perform cycle ergometer exercise at a workload corresponding to 50% peak V・o2 for 40 min followed by a workload corresponding to 70% peak V・o2 until exhaustion. Fat oxidation was significantly increased in the MCT + CHO trial (13.3 ± 2.7 g/40 min, mean ± SD, p < 0.05) during moderate-intensity exercise and the duration was extended significantly (23.5 ± 19.4 min, p < 0.05) during subsequent high-intensity exercise, compared with that observed in the CHO trial (fat oxidation; 11.7 ± 2.8 g/40 min, duration; 17.6 ± 16.1 min). In conclusion, continuous ingestion of 6 g MCT with maltodextrin could increase fat oxidation during moderate-intensity exercise and extend the duration of subsequent high-intensity exercise in recreational athletes, compared with the ingestion of isoenergic maltodextrin alone.

In 1985, an interesting report that helps understand the relation between the population and the labor market was published. This report, 21 Seiki no Sarari-man Shakai, made forecasts on changes in the Japanese employment system toward the year 2000 by forecasting the manpower requirements in various occupations and analyzing the impact of the baby boomers on the labor market.Looking back over this past forecast and learning from its experience, this paper makes projections in the following two areas.The first is a forecast of the manpower requirements by industry and occupation in 2015. The report, based on a consideration of both the change of population by age and structural changes in industry, makes clear that there will be a large mismatch of supply and demand in the labor force. In particular, the service industry sector will experience a shortage of 2.34 million workers and the there will be a shortage of 1.67 million professionals. Conversely there will be too many manufacturing and technical workers. These dramatic changes will accelerate mobility in employment, it projects, to a level above the figure projected in the report in 1985.The second is an analysis of the relation between the number of workers and wages, an indicator of the quality of labor, during three decades of 1976-2006. The main results are as follows.1) Based on an analysis of relative wages by age group, the ratio of wages of the group in their fifties divided by that of those in their twenties, and of the number of workers in same age groups, it is possible to conclude that the shock of increasing numbers of seniors has been absorbed and that the seniority management system has been maintained through a decline in the wages of seniors relative to the young.2) Based on the same approach, looking at the relative wages and number of workers by educational background, the relative wage of university graduates to high school graduates has been rising among workers in their thirties and forties even as the number of university educated graduates has increased. This suggests the important policy implication that university is never an over-investment in education because the labor demand for university graduates is rising compared to that for high school graduates within the changing labor market.

The relationship between mindfulness, psychological competitive abilities and mood states were investigated among Japanese university athletes.Athletes (N=233, 169 men and 64 women, mean age 18.51 years, SD=1.16) responded to a questionnaire package comprising the Athletes Mindfulness Questionnaire, the Diagnostic Inventory of Psychological Competitive Ability for Athletes 3 (DIPCA. 3), and the Japanese version of the Profile of Moods States short version (POMS).Results indicated that athletes with high compared to low mindfulness scores had higher scores for self-control, ability to relax, concentration, confidence, decision, judgment, as well as higher total DIPCA. 3, and lower score for total POMS scores. Furthermore, mediation analyses indicated direct and indirect associations between mindfulness and total mood disturbance through self-control and ability to relax skills of the DIPCA. 3.These results suggest that mindfulness is one predictor of psychological aspects of performance and mental health of athletes.

Researchers have hypothesized that narcissists mask their implicit sense of self-dislike by constructing a grandiose self-representation. Several studies have tested this “mask model” using measures of implicit self-esteem, but no study has been done with a Japanese sample. In this study, the Implicit Association Test (Study 1; n=62) and a name letter task (Study 2; n=102) were administrated to measure the implicit self-esteem of Japanese undergraduates. The relationship between implicit self-esteem and narcissism was examined, and the results did not support the mask model. This result is similar to recent findings from a meta-analysis of the mask model of narcissism.
