DEREGULATION AND JAPAN'S INDUSTRY : THE CASE OF THE PETROLEUM INDUSTRY
Takeo Kikkawa 연세대학교 동서문제연구원 2000 Global economic review Vol.29 No.3
Currently, most of Japan's regulated industries are in a bottleneck situation characterized by the combination of on-going deregulation with no progress being witnessed in the series of radical reform. In trying to break away from this bottleneck situation neither calling off the on-going deregulation, Policy A, nor continuing to endorse the common assumption that 'it is sufficient if a semblance of deregulation is achieved,' Policy B, is desirable. Policy A ignores the aspect of industrial regulation causing the industry's fragility, the mutually amplifying effect while Policy B makes light of the aspect of industry fragility conversely generating government involvement.
Study on operation and disposed wastes in hazardous waste landfill
( Rintaro Kikkawa ),( Yasumasatojo ),( Toshihiko Matsuto ),( Takayuki Matsuo ) 한국폐기물자원순환학회(구 한국폐기물학회) 2019 한국폐기물자원순환학회 심포지움 Vol.2019 No.1
In Japan, industrial waste landfill is classified into three types and the one is hazardous waste landfill. This type of landfill accepts hazardous industrial waste (e.g. sludge or dust which exceeds the leaching criteria on hazardous substances) and isolates the waste from external environment by rigid structure with impervious thick concrete walls (over 35cm). It was reported that at present there are 24 sites in Japan according to a report by Ministry of the Environment (MOE). However, there are many unknowns, since few researches had been performed up to now. Thus, in this study, the objective was set to identify the current situation of these hazardous waste landfills, especially regarding the kinds of waste disposed of into such sites. The paths from generators to the landfills were supposed to be like Fig. 1. Therefore, at first, situation of the generation sources of industrial hazardous waste were surveyed based on the reports published by MOE. The types of hazardous waste generated and their amount can be found. The amount of hazardous waste generated annually in nationwide was approximately three million ton and major categories were waste acid, waste alkali and waste oil. The amount of their final disposal varied widely with the year and predominant categories were waste alkali and waste oil. However, the amount of hazardous waste which was disposed of into the hazardous waste landfill couldn’t be made clear due to no clear description on the landfill type used. Thus, reports submitted by waste generators to prefectures were investigated next. As a result, the number of generators was 2231 in total, which was too many to investigated them individually. In addition, most waste generators entrust their hazardous waste treatment to the private waste treatment companies. Considering these facts, records of waste treatment companies should be investigated. The reports submitted by waste treatment companies to the regulatory authority (prefectures) were not published officially. Thus, we made disclosure request on the reports to a prefecture in which hazardous waste landfill exists. According to the reports, it was found that there were five facilities treating hazardous waste and only one facility operated hazardous waste landfill in Hokkaido. Since 19 waste generators were identified as the clients of final disposal to the site, interview and questionnaire survey for them were conducted. As a result, the kind and amount of waste in the site were known as indicated in Fig. 2. The largest fraction of the waste, which was disposed of as “sludge” or “slag”, was the waste caster materials used in thermal waste treatment plant. They became hazardous waste because they contained much Cr (VI) to resist to high temperature inside the furnaces. Besides, CRT glasses (containing Pb), waste sand coming from sand blast (Pb), and sludge from hot spring drainage (As) were disposed of as “sludge”. And dust from electric furnaces (Pb/Cd) and dust from crematories (Cr) were disposed of as “dust”.

A method of improving the resolution of the detected blood glucose level by using the microwave detection technique is proposed in this paper. In this proposed method, the matrix pencil method and the artifi cial neural network are combined to help improve the resolution of the detected blood glucose level. The matrix pencil method is applied to extract the poles of the received microwave signals. And the artifi cial neural network which is very popular in the artifi cial intelligence fi eld in recent years is also utilized to help distinguish the blood glucose level by training the poles extracted from the received signals. The reliability of the method is checked by establishing an earlobe model which is more realistic than it is in the former research. The mean error between the real blood glucose level and the detected blood glucose can be 0.09957% which is minor than 0.1%. The correctness of the method is testifi ed by successfully detecting the blood glucose level with the precision of 1 mg/dl. The UWB microwave detection system can satisfy the detection of the normal range of the plasma glucose level 70–240 mg/dl.
Spalling of the Oxide Scales Foemed on Stainless Steels During Cooling
Saeki, Isao,Ogama, Tetsuro,Furuichi, Ryusaburo,Kikkawa, Shinichi 한국부식방식학회 2003 Corrosion Science and Technology Vol.2 No.5
High temperature oxidation of SUS430 and SUS304 stainless steels in 16.7 kPa O₂ - 20.3 kPa H₂O- balanced N2 atmosphere at 1273 K was studied focused on the scale spalling during cooling after an isothermal oxidation. Spalling of the oxide scale during cooling occurred only for SUS304 stainless steel. The oxide scale was composed of two layers and they detached at the interface between them. The reason for the spalling could not be explained only by thermal stresses applied to the specimen during heating and cooling. A new mechanism for scale spalling was proposed based on combination of thermal stresses and thermal shock caused by a fast Martensite transformation of substrate metal.
