Effects of wood vinegar (WV) on red mites, safety test for chicks, and egg production performance were examined. In the counting of red mite numbers at cage knots using RGB color range of red mites by the image analyzer, the red mite were decreased after spraying (P<0.01). In a WV safety test for 8-day-old chicks, one ml of water, original WV, or WV diluted 500 and 1,000 times were tube-fed twice daily for 6 days. The rate of body weight gain was decreased in original WV group than that in the control (P<0.05), but it was not different in both WV dilution groups compared with that in the water-only group. In spraying one ml WV to the hen’s face twice per day for 8 days, the egg production performances of WV group did not changed so much compared with those of the control and initial day. These results suggest that the WV did not reduced production performance.From these results, WV could exterminate red mites, and did not reduce egg production, suggesting that WV is a useful natural substance to exterminate red mites without harmful effect.

It is the object of this paper to make clear the reason of the formation of the Settan type which is the characteristic plan type among many types of the farm houses in the Edo period. Settan type is featured by having the entrance on the gable side. Judging from some of the oldest ermains in the seventeenth century, the plan of this type consisted of three chanmbers arranged in single file and dirty floor to parallel with them. Each of the chambers is called 'Zashiki' (parlor), 'Daidokoro' (living and dinning), and 'Nando' (bed room) from the front to the back. Zashiki has a wide veranda in frant of itself. Conseqently, Settan type constitutes the formalized fasade for the farm house. Settan type is distributed over three provinces, Yamashiro, Settsu, and Tanba (equal to Kyoto, Osaka, and Hyogo Prefecture at present time). What does this distribution mean? After many researches, I was aware of the correspondence of this distribution with the dominant area of the Hosokawa who was substantially the execter of the Muromachi Shogunate from the middle of the fifteenth century to the middle of the sixteenth century. In this period, the upper-most class farmers were given the political privelege and played the part of the official ruler of thier villages. On the other hand, it is thought that the residents in the houses belonging to this type in the seventeenth century were the desendants of them. It is conjectured, therefore, that Settan type was formed as the result of emphasizing the social parts in planning, that is a parlor and a wide veranda, in front. In addition to this tendency, probably, the privelege of using 'Hafu' (the triangle board on the gable side of the roof) which had been only used by the upper-class in the Middle Ages, might have been permited to them in return for their special position. As the result, the gable side of their houses might have been put in the front to exaggrate it. The older type planning was re-organized in accompany with these occurrences. Thus, Settan type had been formed in this region by the first half of the sixteenth century.

During the repair of double-strand breaks (DSBs) in DNA, active mobilizations for conformational changes in chromosomes have been widely observed in eukaryotes, from yeast to animal and plant cells. DSB-damaged loci in the yeast genome showed increased mobility and relocation to the nuclear periphery. However, the driving forces behind DSB-induced chromatin dynamics remain unclear. In this study, mathematical models of normal and DSB-damaged yeast chromosomes were developed to simulate their structural dynamics. The effects of histone degradation in the whole nucleus and the change in the physical properties of damaged loci due to the binding of SUMOylated repair proteins were considered in the model of DSB-induced chromosomes based on recent experimental results. The simulation results reproduced DSB-induced changes to structural and dynamical features by which the combination of whole nuclear histone degradation and the rigid structure formation of repair protein accumulations on damaged loci were suggested to be primary contributors to the process by which damaged loci are relocated to the nuclear periphery.

マイナンバーカードの利用で懸念されることは、マイナンバーカードの裏面に記載された個人番号による国民総背番号化と、個人番号とともに収集される特定個人情報の漏えいである。これらを防止するために、マイナンバーカードの裏面に記載された個人番号の利用を法律で定めた場合のみに限定している。しかし、マイナンバーカードのおもて面は公的な身分証明書として使用できることが政府や地方自治体から広報されており、個人番号が記載された裏面のような制限はない。ところが、マイナンバーカードのおもて面には氏名、住所、生年月日、顔写真などが記載されており、これらをスキャンしてデジタル情報にすればコンピュータで個人情報管理に利用できる。この情報は運用次第では個人を特定する情報として利用できる。そこで本論では、マイナンバーカードのおもて面の情報を利用した個人情報管理のリスクと影響を検証してその対応について提言した。

This report presents the computer simulation of a self-organizing system of mutually locked oscillators. It indicates that this many-oscillator system behaves like an amoeboid cell. This result suggests the organization of the amoeboid movement is related to the function of the oscillation induced by mitochondoria.

We investigated the risk factors for vertigo from the results of health checkups conducted in Yakumo town. The subjects of this investigation included 525 persons (299 women and 226 men), aged 40 to 88 years (average 63.78 years). Among these, 397 persons (75.6%) had no vertigo, 116 persons (22.1%) had vertigo sometimes, and 12 persons (2.3%) suffered from vertigo frequently. Ninety-four women (31.4%) and 34 men (15.0%) had vertigo. Twenty-one (51.2%) of the 41 women in their 40s had vertigo. Logistic regression analysis revealed that subjective hearing loss, a low value of the mean corpuscular hemoglobin concentration (MCHC), headache, high level of serum creatinine and frequent urination were significantly associated with the risk of vertigo, after adjustments for age and sex. Listening difficulties in conversations between four or five people were reported more frequently than those in one-to-one conversations. Anemia should be considered in the differential diagnosis of vertigo. In the diagnosis of vertigo, information about the presence/absence of headache and the status of the headache, if any, may be necessary. In our study, migraine and headache on the ipsilateral side were associated with vertigo, but bilateral headache was not associated with vertigo. Our analysis, did not reveal smoking, drinking, exercise habit, sleep time, body mass index (BMI), body fat percentage, hemoglobin A1c, blood glucose, serum triglyceride, serum LDL cholesterol, or serum HDL cholesterol as being significantly associated with the risk of occurrence of vertigo, after adjustments for age and sex.

Viscosities of dilute acrylonitrile polymer solution containing various kinds of non-solvent were measured at 30°C and 50°C (in the case of acetone 30°C and 40°C). Intrinsic viscosity [η] and Huggins' constant were calculated and viscosity change with time of concentrated polymer solution were measured.The results obtained are as follows:A) In the case of dilute solution, 1) Nitromethane, acetone, n-hexane and tetrahydrofuran (THF) increase [η] but k′ decreases with increasing amount of them and temperature rises. They behave as poor solvents.2) Dioxane does not change [η] and k′ below 5 volume % benzene behaves as good solvent below 10 volume %, however, it behaves as poor solvent above that content.B) In the case of concentrated solution, Concentrated solution containing n-hexane increases viscosity with time and with the increasing amount. Benzene, THF and dioxane do not cause viscosity increase below a certain amount, however, they increase viscosity with time.

「も」に関しては従来,意味による分類が行われていたが,この論文では構文のタイプが学習者の母語に存在するかしないかによって習得難易度に差があるのではないかという仮説を立て,JFL環境の中国語話者を対象に,3種の調査によってそれを検証した。理解について調べた文法性判断課題においては構文タイプによる差は見られなかった。しかし,産出について調べた翻訳課題ならびに作文課題においては,通常の「AもP」構文の使用に全く問題ない学習者であっても,「AもBもP」構文や「AもP,BもP」構文の使用は難しいという,母語の干渉の存在を支持する結果が得られた。この結果は,産出のための文法を考える際には,日本語学の視点のみから記述された文法では不十分で,学習者の母語についても考慮する必要があること,またJFL環境における検証調査の重要性を示している。

天然資源を持たない小国シンガポールにとって「人」の問題は国の死活問題である.そのために,複線型教育制度の導入などを通じて「人の質」を保証しつつ,結婚・出産・子育てへの手厚い支援や外国人労働者の受け入れなどの制度を中心に「人の量」も確保することは,国力を維持・発展させる礎となる.その一方で,人材の質量確保が競争を促し,学校教育段階を終えても「勝ち」にこだわるレースは続く.本稿では,シンガポールの公的統計および現地の若者を対象とした個別面接質問紙調査の結果をもとに,小学校から始まる学歴競争がいかに強固な「トーナメント競争マインドセット」を国民の間に浸透させ,そのことが晩婚化,未婚化,そして少子化といった社会問題につながる可能性があるのかを考察する.

沖縄におけるギャンブルの機会と背景については,以下の知見を提示する。可視化できるギャンブルとしては,パチンコ,宝くじ,スポーツ振興くじのみであるが,リモート投票が進展している公営競技については相当数の会員がいることが推察される。他方,47 都道府県で唯一,公営競技や公営競技施設が未導入の背景としては,1)沖縄が占領下にあった(機会喪失),2)失業率など社会環境の特異性,3)沖縄振興策や地方交付税など沖縄への手厚い経済政策,4)米 軍基地の存在,5)琉球競馬という金銭を伴わない競馬が行われていた実績,6)住民運動に代表される市民力の高さなどが要因として考えられた。

This study aims to clarify the particularity of Land Readjustment Project on the site of U.S. military in Okinawa by tracing the changes and discussions of Master Plan, Land readjustment Plan of the pre-returned area “Shintoshin”. “Shintoshin” is a newly and the biggest case in Okinawa. The methods are hearing to key persons and document analysis. The consequences are followings; 1) Because landowners had high demand of income from own real estate, the Total Floor Area Ratio was pushed up higher than usual, and the Land Use Plan had been converted its concept into a new center district with a big commercial zone. 2) Despite of high popularity in the real-estate market, the central area evaluated extremely low, it was around 70% lower than market price, by roadside land price assessment before Land Readjustment Project. To early success of land acquisition for public institution, the local government has to offer a reasonable price.

The two-storey wooden houses in Naha city played an important role in the urban formation after W. W. II. The concentration of these houses indicates the process of rebuilding of Naha city in early post-war period. As one of the typical urban dwellings, the two-storey wooden houses formed high-density residential communities and were used multifunctionaly. The first floor was usually for shops and the second floor was for residential uses. The renewals of these houses are difficult because of the complication of tenure for the land and for the buildings.

This paper aims to investigate the formative process and the forms of various sales places at postwar Naha public market and surrounding shopping streets. There were various forms of sales such as public market, shopping street, stand, trade under the eaves, street peddler. Each trade reflected their formative process and component and did business under peculiar rights. They developed as a whole significantly although they include various social classes and adversarial relation. Especially, the distinctive feature of postwar Naha is that Shopping street newly generated after the war amalgamated public market as a traditional form since the prewar.
