  • This study is an attempt to quantify rainwater utilization and miscellaneous water demand in Tokyo's 23 special wards, the core of the urban area in Tokyo, Japan, in order to elucidate the potential of further rainwater utilization. The rainwater utilization for miscellaneous appropriate water demands, including toilet flushing, air conditioning, and garden irrigation, were calculated for six different types of building: residential house, office, department store, supermarket, restaurant, and accommodation. Miscellaneous water demands in these different types of building were expressed in terms of equivalent rainfall of 767, 1,133, 3,318, 1,887, 16,574, and 2,227 (mm/yr), respectively, compared with 1,528 mm of Tokyo's average annual precipitation. Building types, numbers and its height were considered in this study area using geographic information system data to quantify miscellaneous water demands and the amount of rainwater utilization in each ward. Area precipitation-demand ratio was used to measure rainwater utilization potential for miscellaneous water demands. Office and commercial areas, such as Chiyoda ward, showed rainwater utilization potentials of <0.3, which was relatively low compared to those wards where many residential houses are located. This is attributed to the relatively high miscellaneous water demand. In light of rainwater utilization based on building level, the introduction of rainwater storage mechanisms with a storage depth of 50 mm for six different types of buildings was considered, and calculated as rainfall of 573, 679, 819, 766, 930, and 787 (mm), respectively. Total rainwater utilization using such storage facilities in each building from 23 wards resulted in the retention of 102,760,000 $m^3$ of water for use in miscellaneous applications annually, and this volume corresponded to 26.3% of annual miscellaneous water demand.

  • Environmental conditions and expected profit are the major criteria to select crops to be cultivated in any region. Traditionally, miscellaneous crops have been cultivated as alternative crop in case of unfavorable climate or supplementary crop in marginal lands. Since the successful breeding of high yielding varieties of staple crops and development of cultural techniques in 1970s in Korea, production of miscellaneous crops decreased markedly due to the rapid commercialization of agriculture and increased productions of horticultural crops, although yields have been doubled during the last $2\~3$ decades. On the other hand, animal husbandry has been developing remarkably parallel with national economic development and the increased consumption of animal products. As a result, imports of feed grains such as corn have increased rapidly, while roughage production became lower than demand. Among miscellaneous crops, corn production increased markedly through the development of hybrids and due to its importance as silage crops. Acreage of corn production including grains, fresh corns and feeding is about 120,000 ha, while acreage of buckwheat is about 5,000 ha and those of other miscellaneous crops decreased to a level of about 1,000 ha. Although miscellaneous crops have low yield potential and are unprofitable due to low price and imports of cheap foreign products, they should be kept to cultivate. Miscellaneous crops are important components that maintain diversity among upland crops as well as alternative crops in case of unfavorable climate. The low yield potential of miscellaneous crops might be due to lack of efforts to breed high yielding varieties and to develope cultural techniques. Continuous investment in research, exploitation of new utilization for miscellaneous crops as sustainable crop, honey crop and sightseeing crop, and development of healthy and special foods will promote their cultivation. Animal feeding in Korea depends mainly on formula feeds. As the number of animals increases to meet demand of animal products, there is no alternative way but to import grains to feed them. But roughage production, which is necessary for normal growth of ruminant animals, should be increased. However, lack of arable land and pasture land limits the production of good roughages. It is estimated that number of course for meat and milk production will be $2.5{\~}2.6$ million and total of $6.2{\~}7.5$ million tons of roughages should be produced. This implies that more than 1 million tons of roughage are needed, although pasture land, upland for forage crops, forage crops after rice cultivation and rice straw are utilized. Therefore, new reclamation of pasture land, increased roughage production in cultivating land, increased cultivation of forage crops after rice, more utilization of rice straw and active exploration of indigenous plant species as roughage resources should be promoted

  • Pseudonoise sequences of period 2$^{m}$ -1 with idel autocorrelation have been researched such as m-sequences, GMW sequences, Legendre sequences, and extended sequences. The m-sequences, the GMW sequences, the Legendre sequences, and the extended sequences are best described in terms of the trace function by previous works. Besides, there are Hall's sextic residue sequences and miscellaneous sequences with ideal autocorrelation, whose general constructions are not known so far. However, are are no explicit descripton of the Hall's sextic residue sequences and the miscellaneous sequences in terms of the trace function. In this paper, the Hall's sextic residue sequences and the miscellaneous sequences of period 2$^{m}$ -1 are expressed as a sum of trace functions. The miscellaneous sequences with ideal autocorrelation, which are newly found by computer search, are also expressed as a sum of trace functions.

  • Human body fluid and humor include not only sweat, joint fluid but also every fluids, for example, blood, essence, kidney essence and marrow. Historically, in the oriental medicine, there are a lot of efforts in order to preserve fluid and humor. In "Treatise on Cold Damage and Miscellaneous Disease (傷寒雜病論)", when treating cold damage, preservation of fluid and humor is put first. I tried to find out the relation about fluid and humor and pain treatment in "Treatise on Cold Damage and Miscellaneous Disease". So, I investigated sentences related to pains in "Treatise on Cold Damage and Miscellaneous Disease" "greater yang disease part" and commentaries of several chinese medical doctors. And I divide pain treatments into four categories. (fluid and humor sufficiency-exterior pattern, fluid and humor sufficiency-interior pattern, fluid and humor deficiency-exterior pattern, fluid and humor deficiency-interior pattern) At first, when treating pains of cold damage, there are many considerations about deficiency and sufficiency of fluid and humor through pulse condition and symptoms. Second, in pain-cases of fluid and humor sufficiency, purge methods is chosen. And in pain-cases of fluid and humor deficiency, tonifying methods is chosen. Finally, one of the main objects of "Treatise on Cold Damage and Miscellaneous Disease" is preservation and supply of fluid and humor.

  • Purpose: The aim of this study is to develop a small combine for harvesting miscellaneous cereal crops. Methods: A prototype small combine was designed and constructed. Its specifications and basic performance were investigated. Results: The prototype small combine for harvesting miscellaneous cereal crops was designed and constructed to reflect similar specifications as those of the conventional combine. The prototype small combine comprises a diesel engine with the rated power/speed of 22.0 kW/2,600 rpm, three-stage primary and two-stage speed range transmission shifts, and a double acting threshing part. The maximum travel speeds of the prototype combine are approximately 0.72 m/s, 2.50 m/s, 0.30 m/s at the low, high speed range shifts in the forward direction, and while traversing in the reverse direction, respectively. The minimum radius of turning was approximately 1.50 m. In a static lateral overturning test, the prototype combine overturned neither to the right nor to left on a $30^{\circ}$ slope. The results of an oilseed rape harvesting test included the maximum operating speed of 0.32 m/s, the grain loss ratio of approximately 9.0%, and the effective field capacity of approximately 10.3 a/h. Additionally, among the outputs in grain outlet, the whole grains, damage grains, and materials other than grain (MOG) ratios accounted for 97.4%, 0.0%, and 2.6%, respectively. Conclusions: The prototype small combine for harvesting miscellaneous cereal crops indicates good driving ability and stability. The results of the oilseed rape harvesting test reveal that the harvesting performance must be enhanced such that the separating and cleaning parts are more suitable for each type of crop, thus reducing grain loss and foreign substances among the outputs in grain outlet. An improved small prototype combine could be used effectively to mechanize the harvesting of miscellaneous cereal crops in small family farms or semi-mountainous areas.

  • "Treatise on cold damage and miscellaneous disease" is a ancient formula records on keeping in good health, provided "Internal classic" is a ancient codes on keep in good health. It can be inferred that Zhang Zhongjing was a first inheritor of academic ideology from "formula followed by establishment of the therapeutic principles". Before writing and compiling the "Treatise on cold damage and miscellaneous disease", Zhang zhongjing got the essence of "Internal classic" after composing and utilizing "Plain Questions", "Miraculous pivot and classic of difficult issues", so all the theory foundations of "Treatise on cold damage and miscellaneous disease" came from "Internal classic". The keynote of internal classic lies in obeying the Yin and Yang in natural world and preserving and maintaining the yang-qi of human body to attain the longest life-span. Zhang assimilated the essence of "Internal classic" and then generated a new ideological system - "Treatise on cold damage and miscellaneous disease" when studying it. This article is to expound ideology inheritance of keeping in good health by protecting Yang in "Internal classic" from analyzing the usage of Guizhi in "treatise on cold damage diseases".
