近年の汎用パーソナルコンピュータに多く使われているIA-32プロセッサは過去との互換性のために命令体系はCISC的である.しかし内部動作はRISCマイクロ命令への変換,ハイパーパイプライン,アウトオブオーダ,などRISC的アーキテクチャが多数取り入れられている.さらにSIMD的演算命令の搭載によりデータ並列処理を実現している.とはいえその新しい機構に応じたコードを生成するコンパイラはまだまだ少数であり,また対応していたとしてもコンパイラ独自の拡張C言語による記述が必要であることが多い.そのため通常のC言語による記述を主体としたベンチマークではプロセッサの正当な評価を行いにくい.そこで我々は実用的なアプリケーションとしてMP3エンコーダを選択しコード全般にわたってアセンブリ言語による最適化処理を行った.その結果C言語によるコードに対し2倍から3倍の高速化を達成した.

Background Parent training (PT) is a promising support for improving parents’ mental health, and behavior in children with autism spectrum disorders (ASD). In recent years, there has been an increase in online PT studies. We developed a prototype for the on-demand PT. In this study, we examined changes in the program implementation, accomplishment of homework, parents’ mental health, and behavior of children among parents of children with ASD.Methods This study participated two mothers of children with ASD. The first was the mother of a child aged three years and eight months with ASD and intellectual disability; the second was the mother of a child aged four years and 5 months who had a diagnosis of ASD. An on-demand PT consisting of six sessions was provided online. The program was structured so that the participants watched lecture videos for each session, answered a confirmation test, and submitted homework to advance to the next session. Feedback for the submitted homework and questions was provided via email by the researchers.Results Both participants watched the program on a schedule for all sessions and submitted all tests and homework assignments. The percentage of correct responses to the tests per session was 100% for both participants. Two of the four target behaviors of the children changed significantly. Pre- and post-questionnaires also showed improvements in the scores of parental depression and parenting stress, as well as overall behavior of the child.Conclusion The program in this study was developed as a prototype for on-demand PT, and two case studies showed positive results. Although this program was on-demand, changes in parent and child behaviors were confirmed by the scale and actual behavior records. Further demonstration is needed to increase the number of cases and to compare the results between the groups.

Geothermal potential area in Japan has been depopulated recently, and there have been distances between the geothermal potentials and most energy consumers living in urban areas. Since 2020, working from home (home-based telework) has spread rapidly due to the influence of the COVID-19. If some of the energy consumers work from the geothermal potential area, namely onsen areas, it would help to reduce the extra fossil fuel consumption, to reduce the environmental impact, and to save commuting costs and time. In this study, we quantitatively evaluated the advantages and feasibility of working from onsen in Naruko area, Osaki City, Miyagi Prefecture, as a case study. The environmental effects were analyzed by using the annual CO2 emissions and the costs, based on the perspective of the form of stay and the life-cycle assessments with four scenario conditions ((a) base system, (b) home-based telework in a city, (c) onsen-based telework (using hot spring only for bathing), and (d) onsen-based telework (using hot spring for bathing and heating)). Compared to the base system, the use of public baths in the onsen area can reduce CO2 emissions by about 1/3, and the use of bathing and heating by hot springs can reduce CO2 emissions by about 1/4. In the case of a short-term stay in the onsen area, the effects of reducing CO2 emission differed depending on the area where the worker is based and the season. The results indicates that some conditions of the short-term stay may results in higher CO2 emission than when nothing is done. Therefore, we expect that each of urban workers, companies, and onsen areas will change their awareness and take actions to be able to stay in the onsen area for a mid- to long-term.

A 67-year-old Japanese woman with a history of contact with a COVID-19 patient presented with a one-day history of fever, malaise, and dyspnea, and was hospitalized with a positive nasopharyngeal swab test for SARS-CoV-2 LAMP. Chest CT revealed bilateral patchy infiltrates. The patient was treated with remdesivir and dexamethasone and supplemental oxygen supplied via a nasal cannula. The supplemental oxygen therapy was continued for 6 days, and the drug administration was completed on the 10th day of hospitalization. The patient was then scheduled to be discharged, when she developed severe hyponatremia with a serum Na level of 110 mEq/L, but no consciousness disorder.The patient was diagnosed as having SIADH after several examinations suggesting higher levels of secretion of antidiuretic hormone, with a higher specific gravity of the urine than that of the serum, in addition to evidence of normal functioning of the thyroid, adrenal, and pituitary glands, and of the liver and kidneys. Whole-body CT showed no evidence of any tumors. The hospitalization was extended for correcting the serum sodium levels by restriction of water intake. It was assumed that the SIADH was caused by COVID-19, presumably by the elevated serum IL-6 levels inducing secretion of ADH, similar to the phenomenon reported in other inflammatory diseases associated with elevated serum IL-6 levels.COVID-19 could lead to SIADH due of unresolved systemic inflammation even in the absence of worsening of the findings of chest imaging after the completion of antiviral treatments. Further studies are required to evaluate the correlation between the inflammatory state (e.g., serum concentration of IL-6) and serum ADH level causing hyponatremia during the clinical course of COVID-19.

Two distinctive species of Amphipoda are described from the Ariake Sea in Japan. Scutischyrocerus japonicus sp. nov. (Family Ischyroceridae) is characterized by the cylindrical shape and the shield-like coxae 2–5. This new species differs from S. scutatus Myers, 1995 in the uropods with peduncles bearing many plumose setae. In the second species, Ledoyerella clavata (Hirayama, 1984) comb. nov. (Family Kamakidae), the lateral cephalic lobe is strongly produced, and the gnathopods 1, 2 of both sexes are the same size, with the propodus being almost as long as the carpus. This species can be distinguished from its congeners by the heavily setose posterior margins of pereopods 6, 7 bases. Ledoyerella spinosa Ren, 2006 is synonymized with this species.

This paper focuses on the concept and purpose of borders or frontiers in ancient Egypt from a geographical view.Egypt is surrounded by desert on both sides of the Nile. The natural environment and isolated geographical location formed a natural barrier from foreign invasions, as well as providing very effective internal communications through the Nile.The borders or frontiers of ancient Egypt were not consistent throughout history. They were not easily distinguishable by the lines of demarcation. Particularly away from the Nile, aecumene regions or ‘empty lands’ were geographically stretched out very wide.The Definition of a border or frontier in ancient Egypt is diverse and sometimes contradictory. Historically they represent delineations of geographical, political, administrative, religious and cosmological order: aspects different from the modern borders or frontiers. Two terms which may be recognized as an expression of the borders and frontiers are in hieroglyphics: t3š expresses the actual geographical borders, and drw expresses the end of the cosmos, and frontiers far beyond the range of t3š.When considering either the borders or frontiers of ancient Egypt from a functional point of view, at least five types can be considered: natural, administrative, political, religious, and ethnic borders or frontiers. Each had its own function and geographical range.Natural borders were very stable geographically and geomorphologically only limited to the Nile Valley down to the First Cataract and the desert margins to the both sides of the Nile in the Delta regions. Administrative borders delineated by the margins of the frontier nomes were almost equal to the natural borders during the Dynastic era. The administrative borders extended much further than the natural borders at the Greco-Roman era by the establishment of new nomes outside of the traditional range of Egypt. Political borders, de facto limits of the state, were rather dynamic in its expansion, according to the foreign affairs. Guarding the borders from the foreign invaders and bedouins was recognized as one of the most important tasks for the pharaohs to undertake as lords of not only Upper and Lower Egypt, but also of foreign lands, beyond the borders of Egypt. Ethnic frontiers were not clearly distinguishable expect through their difference in faith, language and customs.The activities of the agricultural production were not typically in the frontier regions. The temples, military parks, custom posts and fortresses were scattered and placed in strategic points in the frontier zones, near trading centers with the neighboring countries. Their location represented the geographical distance of the frontier as well as their position with respect to their neighbors.

The present paper is the report of a part of the investigation on the Chin-shu-yin-i (the Phonetic Glosses to the Chronide of the Chin Dynasty) by Ho Ch’ao 何超 (ca. 740 A. D.). This investigation forms a part of the writer’s main study on the phonology of Chinese of the T’ang Dynasty together with the previous studies of the writer on the phonetic glosses in the Han-shu 漢書, the Chi-chiu-p’ien 急就篇, and both the So-yin 索隠, and the Chêng-i 正義 Commentaries of the Shih-chi 史記 which were already published, including a study on the Hou-han-shu-yin-i 後漢書音義 (the Phonetic Glosses to the Chronicle of the Later Han Dynasty) which will appear soon.After having made clear the phonological peculiarities on the basis of the analysis of the phonetic glosses, the writer has pointed out in this paper that the Chin-shu-yin-i has incorporated some phonetic modifications which had been produced or were in progress during the T’ang Dynasty into the basic system of the Ch’ieh-yün 切韻 (601 A. D.) that is supposed to have remained as the authority of the reading of the Chinese characters throughout the reign of the T’ang Dynasty. Further,the writer corroborates his hypothesis that besides the norm of the Ch’ieh-yün another tradition of reading was maintained exclusively among the T’ang scholars (cf. S. ȎSHIMA, “A Phonological Study on the So-yin and the Chêng-i Commentaries to the Shih-chi”, the Tōyō Gakuhō Vol. 55, No. 3, 1972), since the phon6logical peculiarities reflected in the Chin-shu-yin-i are identical in nature with those found in the So-yin Commentary (between 719 and 736 A. D.) and the Chêng-i Commentary (736 A. D.), both of which were compiled practically at the same time as the Chin-shu-yin-yi was written. It can be added that the phonological peculiarities reflected in Yen Shih-ku 顔師古’s Han-shu-yin-i 漢書音義 (641 A. D.) and Chi-chiu p’ien-chu 急就篇注 (between 627 and 644 A. D.) support this supposition. (cf. S. ȎSHIMA, “A Study on the Finals of Yen Shih-ku’s Phonetic Glosses to the Han-shu”, the Gengo-Kenkyū, Vol. 59, 1971; S. ȎSHIMA, “A Study on the Phonetic Glosses in Yen Shih-ku’s Commentary on the Chi-chiu-p’ien”, the Memoirs of the Faculty of Letters of the Hokkaidō University, Vol. 22, No. 1, 1974).The writer also touches in this paper on the methodology of a phonetic history based on fragmentary sources like the phonetic glosses. According to the writer, aberrant readings appearing in fragmentary sources such as found in the phonetic glosses do not always reflect the results of real phonetic changes, but may show the traditional readings as they were orally transmitted from teachers to their disciples. Therefore, these two should be clearly distinguished for a careful observation. For the purpose, the writer believes, a comparative study between all the phonetic commentaries is necessary besides the “projection” method in the treatment of phonetic glosses in one phonetic commentary, (i. e. the method intended to find out divergences between the system of the Ch’ieh-yü and that of the phonetic commentary in question, by projecting the reading of a certain character on the system of the Ch’ieh-yün). The writer pays attention to this idea by citing concrete examples and waits for a further study in future.
