We develop a multi-purpose cockpit system which enables an operator to control various robots remotely. The system consists of multiple screens, a multi-purpose haptic device, and a touch screen interface. The screens provide the states of robot, the image captured by a camera on the robot, and a virtual 3D environment constructed by using the robot controlled remotely. The multi-purpose haptic is a control stick which enables the operator to control the robot with various operation manners by deforming its configuration. Although the operation manner can be changed by using the touch screen interface, the manner is desirable to be selected in a popup menu which appears on the screen. In this paper, a position determination of the popup menu using a low cost head tracker is introduced. A fixation point of the operator on the screen is estimated by use of the head tracker. The popup menu appears in the place which the operator is looking at, and can be operated by switches added on the grip of the haptic-device. Usability of the implemented functions are confirmed in simple experiments.

Lasso peptides are ribosomally synthesized and posttranslationally modified peptides with diverse biological functions. Recent genome mining has revealed that many species of actinomycetes possibly contain biosynthetic gene clusters of lasso peptides. With genome mining for lasso peptide biosynthesis, we screened several actinomycetes for lasso peptide production using high-performance liquid chromatography and electrospray ionization– mass spectrometry. Consequently, Streptomyces cattleya was identified as a producer of a new lasso peptide named cattlecin. Analysis of amino acid content on cattlecin indicated the presence of four moles each of Asp and His, three moles each of Gly and Tyr, and one mole of Ser. Tandem mass spectrometry (MS/MS) analysis of cattlecin revealed C-terminal sequence of WHHGWYGWWDD. The peptide sequence (SYHWGDYHDWHHGWYGW WDD) was the expected amino acid sequence of cattlecin based on genome mining. As a result of MS/MS analysis, the amine residue of the first Ser was proposed to form a macrolactam ring with the b-carboxyl residue of the ninth Asp. The biosynthetic gene cluster of cattlecin comprised four genes: catA, catC, catB1, and catB2, which is typical of a lasso peptide biosynthetic gene cluster in actinomycetes.

The aim of this paper is to analyze the structural differences between the TOPIK and the Hangul Language Proficiency Test, which is administered in Japan. In this paper, we confined our attention to the beginner`s level of these two tests and analyzed their test items in terms of pronunciation, vocabulary, grammar, and discourse. As a result, although they have the same name "beginner`s level", these proficiency tests revealed many differences in their distribution of grammatical items. Furthermore, the TOPIK doesn`t have test items concerning pronunciation. Such differences reflect how the two test systems interpret the "beginner`s level", and how they decide what learners need to study at the beginner`s level. From a contrastive linguistic point of view, these proficiency tests have different characteristics because the Hangul Language Proficiency Test introduced such contrastive viewpoints into their test items, while the TOPIK didn`t. We should recognize these differences appropriately for effective use of these two tests. (Tokyo University of Foreign Studies)
대격조사의 유무와 문장의 계층구조 : 《釋譜詳節》·《三綱行實圖》를 중심으로
요시노리, 스가이 국어학회 2004 국어학 Vol.0 No.43
본고는 중세한국어 문헌인 ≪釋譜詳節≫, ≪三綱行實圖≫에서 대격조사가 나타나지 않는 환경을 밝히고자 하는 것이다. ≪釋譜詳節≫에서 수집한 용례(대격으로 간주되는 명사구) 2255개 중, 대격조사가 있는 용례가 1537예, 대격조사가 없는 용례가 718예 있었다. 본고에서는 문장의 계층구조(階層構造)라는 관점을 도입하여 수집한 용례들을 검토·분석하였다. 그 결과, 종속절(從屬節) 중 명사절(名詞節)이나 관형절(冠形節)과 같이 절(節)의 계층에서 하위에 속하는 절의 경우 그 내부에 있는 명사구에 대격조사가 나타나지 않는다는 사실을 밝혔다. 또한 부사절(副詞節)의 경우도 마찬가지로 양태절(樣態節)과 같이 다른 절에 포섭(包攝)되는 절에서는 대격조사가 없는 명사구가 많이 나타났다. The aim of this paper is to study the environment that the accusative case markers appear or not in Middle Korean texts. As a result, 1537 examples (68.2%) have the accusative case markers and the rest, 718 examples (31.8%) don't have the accusative case markers in a total of 2,255 examples. From the viewpoint of the structure of sentences, the objects in subordinate clauses, especially in nominal clauses (verbs combined with nominalization endings) and adnominal clauses (verbs combined with adnominal endings) generally appear without the accusative case markers. These clauses can be grouped in the lower stratum of the sentences. So this paper concludes the appearance of accusative case markers has a relationship with the structure of sentences.

The baculovirus ChaB proteins are conservedin all completely sequenced Lepidopteran NPVs and areannotated as putative DNA binding proteins. In our previousstudy, ORF51, a ChaB homologue from Helicoverpaarmigera single nucleocapsid nucleopolyhedrovirus(HearNPV) was found to be involved in budded virusproduction and DNA replication. In the present study, wecharacterized ORF52 (Ha52), the other ChaB homologousgene in HearNPV. 50-RACE revealed that Ha52 was transcribedfrom a conventional late promoter transcriptionalinitiator motif (TAAG) located 25 nucleotides upstream ofATG. Expression analysis demonstrated that HA52 proteinwas expressed from 48 to 96 h post infection. Western blotanalysis of virions from both budded viruses (BVs) andocclusion-derived viruses (ODVs) indicated that HA52 wasa structural component of nucleocapsid from ODV. Tostudy the function of Ha52 in the life cycle of HearNPV,Ha52-knockout and Ha52-restored viruses were generatedby the Bac-to-Bac system. Growth curve analyses showedthat the level of BV production in cells infected with Ha52null virus was similar to those infected with wild-typebacmid derived virus. However, bioassay showed thatdeletion of Ha52 significantly decreased the per os infectivityof HearNPV. Taken together, our results indicatedthat, unlike the previously characterized baculovirual ChaBgenes, Ha52 may be involved in HearNPV per os infection.
