| Abstract | In Indonesia, municipal solid waste (MSW) is becoming increasing complex due to variety of reasons like the increasing quantity of MSW, rising public awareness and municipal administration policies in different cities and surrounding regencies. After the landslide accident at Bandung city disposal site, most of related agencies are trying their level best to improve the situation. Against this backdrop, this paper attempts to analyze the present system of MSW addressing variety of aspects such as quantity and composition of MSW being generated, operational management, legal system as well as financial aspect. The systematic assessment has revealed the problem like lack of legal framework, low coverage, improper waste storage, less encouragement for composting, and lack of proper disposal practices. Finally, an action plan is presenting suggestion for immediate and future addressing the issues like the operational management, institutional, financial aspect, public participation & environmental education. |

| Abstract | Regional development and regional planning subjects are very closely linked with the development projects in Turkey as much as in the world. The main applications and studies are usually based on the elimination of disparities among regions. Within this framework, this study has firstly aimed to set out the regional development objectives in Turkey. Secondly, we tried to find out the effect of new regional approaches on Turkish regional structure. Hence, as an approach different from other studies, we focused on NUTS (Nomenclature of Territorial Units for Statistics) regions instead of geographical units (regions) studies. In the following parts of the study, thirdly, the efforts of Turkey about the regional development have been discussed and assessed by using Neoclassic Growth Model in terms of per capita income distributions for new region groups. To compare the results of analysis among regional units, the most important development projects for Turkey were also taken as a different approach unlike other sudies. Previous studies based on geographic regions showed that the basic tendency of per capita income distribution is 'Divergence' unlike expected 'Convergence' in Turkey, but in our study, we found more optimistic results for Turkey, in which per capita income distributions have a tendency to converge after 1997. |

| Abstract | The homogenization method is used to model steel fiber reinforced concrete SFRC by converting the random distribution of fibers to a periodic one. The periodic distribution is chosen to hold similar properties of the composite material in both perpendicular directions to represent an average approximation for the random distribution. The material is modeled as a composite with brittle matrix and elastic fibers. Two patterns of the unit cell are examined to establish the homogenized stiffiness matrix in elastic and plastic stages. A rigid plastic bonding is considered between matrix and fibers. The smeared crack model is used to represent the nonlinearity of concrete. The validity of the homogenized model is examined by comparing the numerical results with the experimental results. The results show good agreement with the experimental work when a suitable pattern of the unit cell is used. |

| Abstract | This study aims to examine the Southeastern Anatolia Project in Turkey, which contains irrigation, energy and drinking water development schemes. The project is the biggest regional development effort ever undertaken by Turkish Government and has influenced the sustainable economic and human development targets. With the completion of each step of the project, it has been expected that there have been many important economic and social changes in Turkish regions, especially the southeast part of Turkey (called as "Southeastern Anatolia Region") and its surrounding areas. The project also interests in both Turkey and its related regions and sustainability is a major issue of concern. Following a brief introduction of the project, the paper examines the type of recent social-economic changes in the region and Turkey in terms of sustainable development components. Under the light of our investigations from different perspectives, it is observed that GAP region with its development project is very far from expectations in the point of sustainability. |

| Abstract | The Asahi River Dam reservoir is one of the important fresh water resources in Okayama, Japan, and its eutrophication has been noted since the 1980s. Therefore, aeration has been applied to control the growth of phytoplankton. In this study, we discussed the effect of aeration and water-intake depth on the water quality distribution in the reservoir, based on numerical simulation and observation. The principal conclusions were as follows:(1) The numerical simulation models applied here reproduced observations fairly well. (2) Water intake from the surfacce layer reduced the concentration of chlorophyll a in the surface layers. Water intake from the middle or bottom layer improved the deficit of dissolved oxygen in the bottom layers. (3) Aeration together with water intake from the middle or bottom layer improved the deficit of dissolved oxygen in the bottom layers. |

| Abstract | Liquid phase oxidation of benzene to phenol was carried out with O(2) using carbon-based Fe-Pd and Cu-Pd catalysts at 40℃. The carbon-based Fe-Pd and Cu-Pd catalyst were prepared by modified carbothermal reduction of metal ion exchange method using cation exchange resin as a source of carbon. Fe/carbon, Cu/carbon and Pd/carbon were not effective for the oxidation of benzene to phenol with O(2) when H(2) was used as a catalyst reducing agent, however both Fe/carbon and Cu/carbon catalysts revealed activities when ascorbic acid was used as a reducing agent. Bimetallic catalysts such as Fe-Pd/carbon and Cu-Pd/carbon showed much higher activity for phenol production than the monometallic catalysts even when H(2) was used a reducing agent. Catalytic activity of Fe-Pd catalyst was much (ca. 2.5 times) higher than the Cu-Pd/catalyst. A physical mixture of the single component catalysts such as Fe and Pd or Cu and Pd were not effective in the oxidation of benzene to phenol, suggesting that an intimate contact between Fe or Cu species with Pd species is necessary to formulate an active catalyst. |

| Abstract | Recently, thermo-responsive polymer gels have been studied in various research fields such as drug delivery system. One of represetative thermo-responsive polymer gels is poly(N-isopropylacrylamide) gel (PNIPAAm) that has a rapid and reversible volume phase transition. However, PNIPAAm is not biodegradable, resulting in limitation of its use in medical fields. Novel thermo-responsive polymer gel was prepared by closslinking of isopropylamine modified poly(succinimide) (IPA-PSI) (Poly[α,β -(DL-aspartate isopropyl amide)-co-(succinimide)]) with hexamethylenediamine. Because of peptide bonds in backbone, therefore, it is expected to possess biodegradability and biocompatibility. These gels changed their volume in response to change of environment such as temperature, pH and concentration of salt in water. Crosslinkage density and substitution degree of IPA-PSI affected volume phase transition bahavior of the gel. |

| Abstract | Homo-and copolymers of poly(lactic acid) have gathered much attention because of their biodegradability and biocompatibility. They have numerous applications in the biomedical field due to their potential. In their polymers, we are interested in poly(lactic acid)-poly(ethylene glycol) block polymers. The amphiphilic triblock copolymers, poly(DL-lactic acid)-poly(ethylene glycol)-poly(DL-lactic acid)(PLEL), have known to be surface-active ability. Therefore, we have studied emulsification properties with the polymers. PLEL were prepared by ring-opening copolymerization of DL-lactide and poly(ethylene glycol) catalyzed by stannous 2-ethylhexanoate. We prepared ethyl acetate-water-PLEL emulsion and applied this emulsion to biodegradable polymer scaffolds. PLA scaffolds were prepared by an emulsion freeze-drying method. These scaffolds were made by varying water weight fraction. Their surface pore size became larger with increasing water weight fraction. |

| Abstract | Let A/R be a ring extension and P a subset of Hom(A(R),A(R)). In his paper [5], K. Kishimoto introduced the notion of a P-Galois extension and gave several basic properties of these extensions. The author showed that these extensions are closely related to Hopf Galois extensions and the structure of quadratic or cubic P-Galois extensions over a field were given in [9] and [10]. Recently,the author classify commutative quartic P-Galois extensions over a field of characteristic not 2 in [11]. Continuing [11], we treat commutative quartic P-Galois extensions over a field of characteristic 2. |

| Abstract | There have been proposed so far many methods of statistical diagnostics in Cox regression for checking the goodness of the estimated model or checking the adequacy of the data. The former type contains the checking of the overall goodness of fit, the validity of the assumption of proportional hazards and the proper functional forms of the effects of covariates. While the latter type contains the checking whether there exist singly and/or jointly influential observations in the data set. In the present paper we study numerically the performances of various methods of diagnostics including our method of influence analysis for multiple-case diagnostics (Sung and Tanaka, 2003) by analyzing a real data set of lung cancer patients. |

| Author | Luo, Yanjuan| Ichiminami, Fumikazu| |
| Abstract | The aim of the study is to explain the present condition of the rows-of-houses preservation policy of Okayama Prefecture and to examine the samples in Maniwa city, Katsuyama area. Besides, the interview investigation was mainly conducted for residents in the rows-of-houses of preservation area in Katsuyama for giving the concluding remarks about the findings. The traditional private houses in Katsuyama preservation area were partially restored in the 1985-89 and 1993-97 fiscal years by the subsidy from the prefecture. Furthermore, Katsuyamacho at that time founded the subsidy system for maintaining rows-of-houses preservation area (about 25.3 ha) independently in 1993, restored 9 private houses, and made and updated the shop curtains; "Noren". In the point of the observable items, the ground warehouse of structures with gable tile-roofing is visible and it is also in use. Moreover, a latticed window structure, a white wall, and a sea cucumber wall constitute the charm of new rows-of-houses. A stone pavement follows on the riverside at the site facing the Asahi River. There are the remains of an arrival-and-departure place of a flat boat and a brewery, etc. According to our investigation in 2002, the residents were satisfied with "It is easy to live quietly", "the beauty of a natural landscape", "harmony of rows-of-houses and a shop curtain", and "a historical atmosphere", but the recognition of "the creation of active rows-of-houses" was unexpectedly low. Therefore, cooperation between residents and informational sharing are much more required. Consequently, since both the visitors and the residents are satisfied very much with each facilities, such as the whole rows-of-houses, a samurai residence, a brewery, and a restaurant etc., town planning is well organized and attained the priority targets. |

| Abstract | The study addresses the influence of bumpers as reduction measures at the bridge decks. The considered devices are steel spring, steel spring with additional viscous damper or steel spring with additional friction element. Gap between bridge decks remains. The reduction measure is placed at one end of the neighbouring girders. The considered earthquakes are the 1994 Northridge earthquake and the 1995 Kobe earthquake. For the nonlinear analysis a finite element method is used. The investigation shows that compared to the other measures the best reduction of the pounding force can be achieved with a friction device. |

| Abstract | In this paper, diversity of agricultural production and its change was examined for some 45 years in Japan and for 1960, 1980, and 2000 in Tottori prefecture. The concept of entropy was used in order to measure the diversity of the agricultural production which consists of some sections. Agricultural production section in Japan has been diversified in the long run. The ratio of rice has been decreasing gradually for a policy of cutting back on the acreage under cultivation. Although the ratio of stock raising and fruits has increased, it tends in recent years to stagnate. The rate of vegetables has increased remarkably. Combination type for every municipalities was determined with the standard value A method, and complemented examination of agricultural diversity. |

| Abstract | More than billions of years, Earth activity and earthquakes have functioned as the most important part in shaping the physical features of our Earth, on both social life and environment. Its unavoidable results always change life styles and city's structures with its positive and negative effects. To diminish those negative effects or avoid precise earthquake hazard, informing society is very crucial that the strong awareness decreases the risk as seen from past experiences all around the world. The research technique is functioned as questionnaire and applied in the area to achieve more realistic information and to maintain the essential arguments. All along the study, it is tried to think up the earthquake phenomena well known and straightforwardly recognized by a considerable quantity of people. Consequently, it is observed in this study that; firstly, telecommunication is most selected item both before and after earthquake in the point of its effectiveness. Secondly, telecommunication tools more preferable though, public announcement more trusting for society as power of affection on personal decision mechanisms. Thirdly, as a new tendency after earthquake, internet preference increased by means of information source about earthquake. |

| Abstract | While dredged soil is increasing, the processing problem isn't solved. So it is expected to use effectively as the soil material. Although, to use dredged soil, the chemical characteristic must be grasped. It is because acidification cause material (pyrite) can be contained in dredged soil. It causes sulfulic ions when it touches air and has the possibility to become acidification. In this experiment, dredged soil in Kojima Lake was made clear that it contained in pyrite and acidified under the oxidation condition. Accordingly, when using dredged soil as ground resources, it is necessary to use as the soil material such as filling-up reclamation under the deoxidization condition. |

| Abstract | In this decade, 3-dimensional topographic survey has been developed by using the UAV as like drones. With the technique, the complete topographies of the geo-structures can be measured. Although the accurate shapes of the geo-structures can be obtained, the numerical methods as like the finite element method is are not related to the 3-dimensional survey directly. In this research, the finite mesh modelling technique with use of the 3-D topographic survey is developed. The models of the earth-fill embankments formed from measured 3-D data are introduced as the examples. |
