Baba Mamoru,Ibaraki Masanobu,Miura Takako,Aoki Takao,Nakashima Hiroshi,Tanaka Shin-ichiro Meigo Susumu Korean Association for Radiation Protection 2001 방사선방어학회지 Vol.26 No.3

Experimental data have been obtained on the neutron elastic scattering cross sections for 55, 65 and 75 MeV neutrons, and non-elastic scattering cross sections for 40 to 80 MeV neutrons using the $^7Li(p,n)$ neutron source at TIARA of Japan Atomic Energy Research Institute and the TOF method. Data were obtained for C, Si, Fe, Zr, and Pb of natural elements. Elastic scattering data were obtained for 25 laboratory angles between 2.6 and 53.0 that clarified the angular distributions and angle integrated values. The data obtained were compared favorably with recent LA150 data library.

ION BEAM APPLICATION

Baba Mamoru Korean Nuclear Society 2006 Nuclear Engineering and Technology Vol.38 No.4

A brief review is presented on the ion beam application in science and technology. ion beams are used very effectively in various fields of science and technology, on the basis of advance in accelerator technology and experimental techniques for ion beam utilization. Recent progress in this field is reviewed in terms of the direct ion beam utilization like ion beam analysis, and the utilization of neutrons as secondary particles.

SURFACES OF REVOLUTION SATISFYING Δ^IIG = f(G + C)

Baba-Hamed, Chahrazede,Bekkar, Mohammed Korean Mathematical Society 2013 대한수학회보 Vol.50 No.4

In this paper, we study surfaces of revolution without parabolic points in 3-Euclidean space $\mathbb{R}^3$, satisfying the condition ${\Delta}^{II}G=f(G+C)$, where ${\Delta}^{II}$ is the Laplace operator with respect to the second fundamental form, $f$ is a smooth function on the surface and C is a constant vector. Our main results state that surfaces of revolution without parabolic points in $\mathbb{R}^3$ which satisfy the condition ${\Delta}^{II}G=fG$, coincide with surfaces of revolution with non-zero constant Gaussian curvature.

Evaluation of Car Seat Using Reliable and Valid Vehicle Seat Discomfort Survey

Baba Md. Deros,Dian Darina Indah Daruis,Mohd Jailani Mohd Nor 대한산업공학회 2009 Industrial Engineeering & Management Systems Vol.8 No.2

Subjective evaluation has always been regarded as a branch of social science research. Hence, in scientific and especially engineering points of view, its development is always taken for granted despite the importance of its effects on the design and development decisions. In the past, at least two automotive seat survey questionnaires have been developed with high statistical validity and reliability. Nonetheless, both were not local while subjective perception very much depends on demographic background factors. It is felt that since vehicle seat comfort is an important aspect in a seat design, a local sense should be put into the survey that is used as the subjective tool. The proposed vehicle seat discomfort survey questionnaire was developed in dual languages; English and Malay. Malay language is the national language of Malaysia, where the survey was tested. Beside inputs from literatures, key informant interviews helped in establishing the appropriate terms used as survey items. Three experimental runs on two different seats by 22 paid subjects showed that the developed questionnaire is reliable and valid. Furthermore, criterion validity analysis on the survey and previously developed survey showed significant correlation at 0.01 significance level.

Characteristics of spider assemblages of subtropical rice paddy fields in the Yaeyama Islands, Japan

Baba Yuki G.,Ohno Suguru 한국응용곤충학회 2024 Journal of Asia-Pacific Entomology Vol.27 No.1

Spiders are important natural enemies of rice pests in paddy fields. To estimate their roles, it is essential to understand their functional diversity. However, little is known about the spider fauna of paddy fields in sub tropical regions. Here, we investigated spider diversity and species composition in paddy fields in the Yaeyama Islands, in subtropical Japan. We collected 1489 individuals of at least 42 species in 13 families and 7 guilds from rice paddies on Ishigaki, Iriomote, and Yonaguni islands by net sweeping during the first and second crops from 2013 to 2015. The Tetragnathidae (39%), Araneidae (35%), and Thomisidae (18%) were the most abundant families, comprising > 90% of total abundance. Orb web weavers (73%) and ambush hunters (19%) were the most abundant guilds. The most common species were Neoscona theisi (Walckenaer, 1841) (Araneidae) (n = 352), Tetragnatha javana (Thorell, 1890) (Tetragnathidae) (n = 294), and Tetragnatha nitens (Audouin, 1826) (Tet ragnathidae) (n = 94). The results show that the species composition of spiders in subtropical paddy fields is more similar to that in tropical paddy fields in Asia than to that in temperate paddy fields in mainland Japan. Ordination analysis showed that the composition of spiders on Ishigaki island varies greatly with season and year. This study makes a valuable contribution to knowledge of the comprehensive diversity of subtropical spiders associated with rice paddy fields in Japan.

『高麗再雕大藏經』の日本流通と活用 -琉球國を中心として-

( Baba Hisayu Ki ) 東亞大學校附設 石堂傳統文化硏究院 2014 石堂論叢 Vol.0 No.58

14세기 후반부터 16세기 초기에 걸쳐 일본 각지의 권력자들이 조선에 대장경을 요청하여 모두 50질을 하사받으면서 대장경이 일본에 전래되었다. 당시 일본 각지의 권력자들이 어떤 이유로 대장경을 요청하여 그것을 어떻게 활용하였는가를 자세히 알 수 없으나 아시카가(足利)가에서는 사찰에서 행해졌던 장군의 생일기도에서 대장경을 전독하였던 사례가 있었다. 유구국(琉球國)도 일본 각지의 권력자와 마찬가지로 조선에 대장경을 요청하여 하사받았다. 그런데 유구국왕였던 쇼타이큐(尙泰久)는 불교를 신앙하여 가이인 쇼코(芥穩承琥)라는 일본 교토(京都)에서 온 선승(禪僧)에게 귀의하고 있었다. 가이인이 유구불교계의 융성에 큰 영향을 미친 사람이기도 한다. 그래서 이 글에서는 유구국의 대장경 요청 이유와 그 활용에 대해서 교토 선종계(禪宗界)와 가이인의 관계로부터 고찰하였다. 유구국의 대장경 요청 이유는 사찰 건립에 즈음하여 법보인 대장경이 없었기 때문이었으나 실제로는 이것을 전독함으로써 진호국가를 기원하려고 했던 것이다. 이와 같은 사례는 일본 교토의 선종 사찰에서도 있었다. 즉 이것이 장군 생일에 생일기도이다. 생일기도는 장군 개인의 생일을 축하할 뿐만 아니라 사해청평(四海淸平)과 만민안락(萬民安樂)을 기원하기 위해서 행해졌고 이른바 호국기도였다. 이와 같은 기도가 유구국에서도 행해지게 되었다고 추측됨은 일본 교토에서 온 가이인의 영향이 크다. 가이인은 교토 선종 사찰을 모델로 삼아 유구국에서 불교를 융성시키고 나아가 대장경을 전독하여 국가 안녕을 기원하려고 한 것이라 생각된다. From the late 14th century to the early 16th century, Japanese Shogunate and Daimyos imported block books of the Koryo-Tripitaka(고려대장경) at Haein Temple in the Chosen Dynasty period. As a result, 50 sets of printing blocks was granted by the Chosen Dynasty and brought in Japan. But, Ashikaga family(足利家) allowed the Koryo-Tripitaka to be completely released as a prayer for a general`s birthday(生日祈禱). Ryukyu country(琉球國) also required the Chosen Dynasty to send her the Koryo-Tripitaka, and was granted. Shou Taikyu(尙泰久) who was the King of Ryukyu at that time, believed in Buddhism and converted to the Zen Buddhism by a priest called Kaiin-Shoko(芥穩承琥) who came from Kyoto. Kaiin had some kind of influence on the prosperity of the Ryukyu`s Buddhism. Therefore, I considered the reason Ryukyu country required the Tripitaka is directly related to Zen Buddhism world and Kaiin in Kyoto. The Tripitaka was installed in a temple. But, the Rulers of Ryukyu country wished to pray for making a country safe by reciting sutras of the Tripitaka. Such an example is the same as a prayer for a general`s birthday generally performed at a Zen Buddhism temple in Kyoto. It was not only a prayer of congratulating on a general`s birthday, but also further the defense of the fatherland. This prayer came to be carried out in Ryukyu country. Kaiin that came from Kyoto, had great influence with Ryukyu country. I think that he let Buddhism in Ryukyu prosper as Zen Buddhism temples in Kyoto, and let priests recite the sutras of the Tripitaka for national tranquility.
