Hyunsook Lee, Kiyo Kurisu, Keisuke Hanaki
Low Carbon Economy (LCE) , 2013, DOI: 10.4236/lce.2013.43011

To develop the low-carbon society, in addition to the efforts by industrial and commercial sectors, promotion of people’s pro-environmental behaviors (PEBs) has become one of the key issues. Some PEBs have been investigated in previous studies, however, the targets were limited to particular behaviors (i.e., recycling, water saving, electricity saving). The holistic view of understanding the characteristics of PEBs has remained insufficient. In this study, we selected 58 daily PEBs from various fields and investigated people’s practice rates and attitudes in Seoul and Tokyo. The questionnaire surveys were conducted and 2393 (Seoul) and 2220 (Tokyo) valid responses were analyzed. Most PEBs had significantly different practice rates between Seoul and Tokyo. It can be concluded that the surrounding conditions, such as policy and infrastructure, have some influences on these differences. The positions of the reasons to practice or not to practice PEBs were visualized using multiple correspondence analyses. The results indicated that the monetary reason was the common factor for many PEBs, while some PEBs showed different reasons. The socio-demographic effects were not significantly

Application of LCA by Using Midpoint and Endpoint Interpretations for Urban Solid Waste Management  [PDF]
Sora Yi, Kiyo H. Kurisu, Keisuke Hanaki
Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.512107
Abstract: Life cycle assessment (LCA) is one of the most widely used methods of decision support. However, few studies have examined whether stakeholders prefer midpoint or endpoint approaches. In this regard, the present study examines the attitudes toward urban solid waste management, environmental issues, and scenario evaluations by using midpoint and endpoint interpretations of LCA results. This study introduces three types of social groups that typically respond to environmental conflicts: the individualist, hierarchist, and egalitarian groups. Although residents are likely to recognize global impacts as the most important issue, their view is likely to change depending on system and avoided emissions. Consistent with the Seoul Metropolitan Area’s new policy designed to increase the incineration ratio, almost half of all respondents preferred the scenario. Noteworthy is that the respondents’ preference for midpoint and endpoint decision-making tools is not consistent with that in previous studies. Most of the respondents indicated that the midpoint approach would be better in evaluating environmental systems.
The Effect of Information Provision on Pro-Environmental Behaviors  [PDF]
Hyunsook Lee, Kiyo Kurisu, Keisuke Hanaki
Low Carbon Economy (LCE) , 2015, DOI: 10.4236/lce.2015.62005
Abstract: To reduce the environmental load of the household sector, it is important to enhance people’s pro-environmental behaviors (PEBs). Information provision has been considered as one of the possible methods for fostering PEBs. However, previous studies have seldom discussed what type of information is most appropriate for the target behavior. Effective media through which to provide such information should be also discussed. In order to identify the most effective such information, as well as the effectiveness of free papers as media through which to disseminate it, environmental information regarding two behaviors—“My Cup” and “Carbon Cashbag”—was provided through online questionnaires and free papers. Even though the same information was provided in both sources, it was found that the effectiveness of the content depended on the target behavior and region. As lack of information was one of the barriers to “Carbon Cashbag” behavior, it was found that the provision of very basic information improved the intention and practice of the behavior. Higher scores for intention and practice were observed when information was provided through free papers, which could therefore be considered as effective media through which to deliver information about PEBs.

To process biomass energy successfully, it is necessary to incorporate a number of criteria that can be assessed either quantitatively or qualitatively for various biomass scenarios. It is also important to take into account the local people’s preferences and interests in the decision-making process. In this study, preferences of various stakeholders on rice husk use, such as urban households, rural households, rice mill owners, brick kiln owners, government officials, and scientists, were investigated using the Analytic Hierarchy Process. The results were incorporated with objective evaluation that was derived from Life Cycle Assessment. A holistic evaluation of rice-husk use scenarios was conducted. The results showed that rural households, rice mill owners, and brick kiln owners still want to use rice husk in conventional ways, while urban households, government officials, and scientists prefer to use rice husk with new technologies. The results reveal the aspects that each stakeholder thinks important and the conflicts between stakeholders. These can help government officials grasp the preferences of the local people which is important information for decision-making.

Spillover Effect on Families Derived from Environmental Education for Children  [PDF]
Ai Hiramatsu, Kiyo Kurisu, Hiroshi Nakamura, Shuichi Teraki, Keisuke Hanaki
Low Carbon Economy (LCE) , 2014, DOI: 10.4236/lce.2014.52005

Facing the challenge of global warming, greater importance has been placed on learning energy and environment in schools and the energy-saving behaviors of children and their families are encouraged. The authors implemented energy environmental education programs with visualization in elementary and junior high schools, and surveyed changes in the awareness and behavior of children and their families. As for children, the results showed that the programs increased the awareness of effectiveness, while almost no change was observed in other factors. The psychological factors impacting intention and behavior in children were attitude, expectations from parents and expansion of interest. Indicating spillover effect on families derived from education of children, psychological factors and behavior of parents were improved. Awareness of effectiveness and behavior of children had significant effects to the most psychological factors of parents, leading to intentional and behavioral change. Furthermore, behavior of parents got influenced by expectations from children. It was also indicated that the higher the awareness of the child is, the greater the spillover effect on the family as a result of education is.

Top quark mass determination near t\bar{t} threshold at lepton colliders
Y. Kiyo
Physics , 2001,
Abstract: Future e^+ e^- linear colliders will enable us to determine the top quark mass with high accuracy from the measurement of the 1S peak position of (remnant of) toponium. The estimated statistical error in this measurement is about 50 MeV with integrated luminosity of 30 ${\rm fb^{-1}}$. We calculate ${\cal O}(\alpha_s^5 m)$ corrections to the quarkonium 1S energy spectrum in the large-$\beta_0$ approximation to reduce theoretical uncertainties below the corresponding experimental error. We discuss the significance of the ${\cal O}(\alpha_s^5 m)$ corrections and estimate theoretical uncertainties of our prediction.
The WASP and WAVE family proteins
Shusaku Kurisu, Tadaomi Takenawa
Genome Biology , 2009, DOI: 10.1186/gb-2009-10-6-226
Abstract: The human Wiskott-Aldrich syndrome protein (WASP) gene was the first of the WASP and WAVE family genes to be isolated, in 1994, as a mutated gene associated with Wiskott-Aldrich syndrome (WAS), an X-linked recessive disease characterized by immunodeficiency, thrombocytopenia and eczema, clinical features caused by complex defects in lymphocyte and platelet function [1]. Another WASP family member, neural (N-) WASP, was then identified from a proteomic search for mammalian proteins that interact with the Src homology 3 (SH3) domain of growth factor receptor binding protein 2 (Grb2, also known as Ash) [2]. Although expressed ubiquitously, N-WASP is most abundant in the brain - hence its name. The first WAVE protein was identified in humans by our group and another group independently as a WASP-like molecule and was named WAVE and SCAR1, respectively [3,4]. Currently, it is agreed that mammals possess five genes for the WASP and WAVE family, WASP, N-WASP, WAVE1/SCAR1, WAVE2, and WAVE3 [5-9]. Human WASP and WAVE family genes are located on different chromosomes, with each gene showing a unique expression pattern (Figure 1). The human WASP gene is carried on the X chromosome and is expressed exclusively in hematopoietic cells, which explains the inheritance pattern and the immunodeficiency and platelet deficiency characteristic of WAS. WAVE1 and WAVE3 are strongly enriched in the brain and are moderately expressed in some hematopoietic lineages, whereas WAVE2 appears to be ubiquitous.Human WASP and WAVE proteins are between 498 and 559 amino acids long and are encoded by 9 to 12 exons. The length of the genes is relatively similar, ranging from 67.1 kb for N-WASP to 131.2 kb for WAVE3, with the exception of WASP, which is a compact 7.6 kb. The restricted expression of WASP in hematopoietic cells is dependent on a 137-bp region upstream of the transcription start site [10]. It is unclear how brain-specific expression of WAVE1 and WAVE3 is regulated, but the proximal promo
More on Large $Q^2$ Events with Polarized Beams
J. Hashida,Y. Kiyo
Physics , 1998, DOI: 10.1143/PTP.101.775
Abstract: We discuss polarized proton-positron scattering in the context of the excess of large $Q^2$ events at HERA. We define and estimate a polarized asymmetry to examine two scenarios, the contact interaction and the stop scenario with broken R-parity. This asymmetry exhibits a characteristic behavior depending on the scenarios. Thus the polarized experiment at HERA will provide with a good test for these models.
Perturbative heavy quarkonium spectrum at next-to-next-to-next-to-leading order
Y. Kiyo,Y. Sumino
Physics , 2013, DOI: 10.1016/j.physletb.2014.01.030
Abstract: We compute the energy levels of some of the lower-lying heavy quarkonium states perturbatively up to O(alpha_s^5*m) and O(alpha_s^5*m*log[alpha_s]). Stability of the predictions depends crucially on the unknown 4-loop pole-MSbar mass relation. We discuss the current status of the predictions with respect to the observed bottomonium spectrum.
Corrections to quarkonium 1S energy level at O(alpha_S^4 m) from non-instantaneous Coulomb vacuum polarization
Y. Kiyo,Y. Sumino
Physics , 2001,
Abstract: We calculate O(alpha_S^4 m) and O(alpha_S^4 m log(alpha_S)) corrections to the quarkonium 1S energy level analytically, which have been overlooked in recent studies. These are the contributions from one Coulomb-gluon exchange with the 1-loop vacuum polarization insertion. A part of the corrections was computed numerically some time ago; we correct its error.
