三重県における農業所得の低位性とその原因に関する研究 : 農家1戸当り農業所得に低位性をもたらす農家経済の構造

application/pdfFarm Household Economy Survey shows that agricural income per farm household of Mie Prefecture in the lowest in Japan. Why does the stagnation of agriculture occur in this region? In spite of the fact that this is a frequent subject of debate, we still can not discover the true reason. The authors discuss this topical question and attempt to provide an insight into this problem. After giving some basic figures concerning the performance of Japanese agriculture from 1957 to 1979，the authors point out that agricultural production other than rice production has been decreasing in Mie, compared with other prefectures in Japan. This fact implies that Mie has been defeated in a competition amongst regions for farm products other than rice during this period. Therefore, Mie agriculture is characterized by its heavy dependence on rice. This is the reason why it is stagnating. No remedies are offered, but the authors are able to provide possibilities which should encourage the regional agriculture. In short, the strategic areas for expansion of production are vegetables, flowers, and ornamental trees and shrubs．departmental bulletin pape

4次元超曲面の曲率を用いた3次元濃淡画像に対する追跡型細線化の一手法

本論文では3次元濃淡画像に対する尾根線追跡型の細線化手法を提案する。本手法は、入力画像の3次元濃淡画像に対して2値化や背景の分離などの前処理を適用することなく直接に適用できる点に特徴がある。本手法は、局所的に濃度値が極大になる点を追跡開始点として、その点から尾根線を追跡していく、という追跡型の細線化手法である。追跡を続ける条件として、4次元超曲面の曲率の三つの主曲率の組合せを用いる。提案手法を人口画像、及び実画像に適用したところ、ほぼ、尾根線と思われる部分を抽出できることが確認できた。journal articl

Temperature dependence of the optical gap of diamond-like carbon films investigated by piezoelectric photothermal and photoluminescence spectroscopies

Since the optical energy gap (Eog) of the diamond-like carbon (DLC) varies over a wide range with the ratio of sp3 (diamond like) to sp2 (graphite like) bonds, it is expected to fabricate the high-efficiency multi-junction solar cells that consists of a single material. In the present study, we investigated the temperature dependence of the Eog of the DLC thin films by using the piezoelectric photothermal (PPT) and photoluminescence (PL) techniques. Because the PPT signal intensity of the present DLC thin film was expected to be proportional to its optical absorption coefficient, Eog was estimated by using a Tauc plot. The values of Eog of the 44%-sp3 ratio sample were estimated to 1.31 and 1.33 eV at 300 and 100 K, respectively. The temperature coefficient then became -6.5 × 10-5 eV/K, and was very smaller than that of Si. This implies that by using the DLC films for solar cell materials, the device performance is expected to be very stable by temperature change.departmental bulletin pape

Rotavirus Genotypes and Vaccine Effectiveness from a Sentinel, Hospital-Based, Surveillance Study for Three Consecutive Rotavirus Seasons in Lebanon

<div><p>Introduction</p><p>Globally, rotavirus (RV) is the leading cause of gastroenteritis (GE) in children. Longitudinal data about changes in RV genotype distribution and vaccine effectiveness (VE) are scarce. This study was conducted in Lebanon over 3 consecutive RV seasons to estimate the rate of RVGE hospitalization, identify RV genotypes, determine the seasonal and geographical variations, and calculate RV VE.</p><p>Materials and Methods</p><p>This prospective, multicenter, hospital-based surveillance study was conducted between 2011 and 2013 and enrolled children (<5 years) admitted for GE. Socio-demographic and clinical data about the current episode of GE at admission were collected. Genotypes were determined from stool samples testing positive for RV by PCR.</p><p>Results</p><p>Of 1,414 cases included in the final analysis, 83% were <2 years old and 55.6% were boys. Median duration of hospitalization was 4 days and 91.6% of GE cases were severe (Vesikari score ≥11). PCR testing showed that 30.3% of subjects were RV-positive of which 62.1% had fever <i>versus</i> 71.1% of RV-negative subjects (<i>P</i> = 0.001). RV was predominantly detected in the cold season from November till March (69.9%). G and P genotype pairs for all RV-positive stool specimens showed a predominance of G1P[8] in 36% (n = 154) of specimens, G9P[8] in 26.4% (n = 113), and G2P[4] in 17.8% (n = 76). RV-negative subjects were more likely to be RV-vaccinated (21%) compared to the RV-positive subjects (11.3%) (<i>P</i><0.001), with a vaccine breakthrough rate of 18.8%. The ratio of RV1-vaccinated for each RV5-vaccinated subject was 7.8 and VE against RV disease was 68.4% (95%CI, 49.6%-80.2%).</p><p>Conclusion</p><p>RV is a major cause of GE requiring hospitalization of children under 5 years of age in Lebanon. A few genotypes predominated over the three RV seasons studied. Mass RV vaccination will likely decrease the burden of hospitalization due to RV. VE is similar to what has been observed for other middle-income countries.</p></div
