Previous workers have reported that Rubus chromosomes are too small for karyotype analyses at mitosis, and also that meiotic studies indicate no major structural differences between Rubus genomes. However, it was found possible to identify the seven chromosomes of Glen Clova, a cultivar of R. idaeus, and of R. coreanus. The chromosomes of R. idaeus differed from those of R. coreanus, four of them appreciably, and it was possible to identify each of the 14 chromosomes of four F1hybrids between the two species. In spite of these differences, meiosis and pollen formation in the hybrids appeared normal. It is suggested that genome differentiation in the genus is greater than realised, and that further karyotype analyses may aid studies of species relationships.

In order to appropriately and quickly handle a security incident, ones may need Incident Tracking System (ITS) that records facts: what happens, when happens, who handles and how. It may be, however, difficult for a person in charge of incident handling to input all detailed information to ITS, and ITS should have minimal but enough information for further incident handling. In addition, a person in charge should be able to operate ITS intuitively since an incident does not happen so often. It is, however, unclear what information ITS should hold and how ITS navigates a person in charge to complete incident handling. This paper discusses these issues, and introduces our implementation and usage of ITS using Redmine within Computer Security Incident Response Team (CSIRT).

Although the claim has been repeated that some version of &ldquo;sound hierarchy&rdquo; is indispensable in the field of phonology, no one has so far offered enough data to prove it.<BR>I conducted the statistical investigations to support explicitly the order of &ldquo;Japanese sound hierarchy&rdquo; using the artificial onomatopoetic words of AB-type. 582 college students who were mainly from Western Japan were asked if they could find a preferred order in&ldquo; pira-pura vs. pura-pira, &rdquo; for example. Chi-square test was used to certify the significance levels of all the minimally contrastive pairs that were grouped into 87 terms. Then, the results were combined to obtain the following.<BR>Vowel Hierarchy: i<u<e<a<o<BR>Consonant Hierarchy: glides<liquids<nanals<fricatives<stops<affricates<BR>In addition, the double-function system was introduced to some exceptional sounds in the consonant hierarchy.

The Coffee Shop called Kopi Tiam in Malaysia is an interesting system of eating house as assembly of hawkers. The independent hawkers with each special meal are assembled by the shop's owner, and the owner provides drink stall and tables for eat. It is similar to Hawker Centre in Singapore or modern food court, but It seems to became a spontaneous system to sustain the quality of foods. The Coffee Shop in Malaysia is analyzed by compared with Hawker Centre in Singapore to clarify the system and know a type of the plan.

For treatment of severe bimaxillary protrusion in adults, a condition known to be among the most difficult to manage, both the maxillary and mandibular anterior teeth must be fully retracted using all the extraction space available. This article reports the treatment of an adult with severe high-angle bimaxillary protrusion. To correct the protrusion of the anterior teeth, orthodontic anchor screws (OASs) were used to provide absolute anchorage during anterior retraction. Acceptable occlusion, facial profile, and balance were achieved. OASs appear to be very useful for treatment of severe bimaxillary protrusion in adults.

The castability, mechanical properties, and fracture characteristics of Ti-15Mo-5Zr-3Al alloy were compared with those of Ti-6Al-7Nb alloy and pure titanium (CP Ti) for application of this β-type titanium alloy in cast dental prostheses. Cast specimens were prepared with a centrifugal casting machine. A tensile test was performed according to ISO standard 22674. The castability index for Ti-15Mo-5Zr-3Al was lower than those for Ti-6Al-7Nb and CP Ti. The tensile strength of Ti-15Mo-5Zr-3Al was 852 MPa, which was lower than that of Ti-6Al-7Nb and higher than that of CP Ti. The proof strength of Ti-15Mo-5Zr-3Al was 799 MPa, which was comparable to that of Ti-6Al-7Nb and higher than that of CP Ti. The elastic modulus of Ti-15Mo-5Zr-3Al was 81.0 GPa, which was lower than the values for Ti-6Al-7Nb and CP Ti. Elongation of Ti-15Mo-5Zr-3Al was 5.1%, which was comparable to that of Ti-6Al-7Nb and less than that of CP Ti. The shape of the fractured segment was narrower for Ti-15Mo-5Zr-3Al than for Ti-6Al-7Nb and CP Ti. The deformation characteristics of Ti-15Mo-5Zr-3Al may result in decreased stress relative to increased strain during plastic deformation in the stress-strain diagram. In conclusion, Ti-15Mo-5Zr-3Al alloy has a low elastic modulus and exhibits limited ductile plastic deformation in cast dental prostheses.

Acrylamide, a probable human carcinogen, is found in a wide range of high-temperature processed and/or cooked foods. Acrylamide is formed mainly from asparagine in Maillard reaction in the presence of reducing sugar such as fructose and glucose. While this compound can be metabolized to glutathione conjugates, it is also oxidized to glycidamide, a genotoxic compound. Glycidamide forms DNA adducts. Acrylamide is also known to have genotoxicity, neurotoxicity, and reproductive and developmental toxicity. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) evaluated health risk of acrylamide in food. The major contributing foods to total intake of acrylamide were found to be French fries, potato chips, coffee, pastry and sweet biscuits, and bread and rolls/toasts. The committee concluded based on national estimates that an intake of 1μg/kg bw per day of acrylamide could be taken to represent the average for the general population. The Committee selected 0.18mg/kg body weight per day as the most sensitive carcinogenicity estimate from animal study data. The margin of exposure (MOE) for the general population was thus calculated to be ca. 200, which is low for carcinogen and indicates human health concern. The Code of Practice for the Reduction of Acrylamide in Foods was published by Codex Alimentarius Commission in 2009 based on scientific analytical data obtained worldwide. Although acrylamide level in foods is decreasing owing to mitigation measures taken by food industry, the MOE is considered to be still staying less than 1000.

The Lionese are an ethnolinguistic group numbering approximately150,000 who inhabit the central part of Flores,Eastern Indonesia. The population of this region is dividedinto numerous traditional domains (tans). These were autonomouspolitical units until early in this century. The dataon which the present study is based were collected during myfield research conducted from May 1983 to March 1985 inTana Lise, one of these traditional Lionese domains.The Lionese economy remains a subsistence one, dependenton the slash-and-burn or swidden cultivation of rice, maize,cassava, sweet potatoes, and various vegetables. Recently cashcrops such as coffee, cloves, and cacao have been introduced inmountainous areas, and irrigated paddy fields are found inflatland in the mountains and near the coast.It is only the swidden agriculture with which multiple andcomplex agricultural rituals are interwoven. These rituals appearto be symbolic behavior apparently related to a cosmologyor world view. But the Lionese people do not know and cannotexplain the symbolic meaning paired with the rituals by asemiological code. They answered my questions about themeaning or purpose of the rituals in a general way by saying'It is our custom' or 'We must perform it that way.' Accordingly,these agricultural rituals are rule-following behaviorrather than symbolic behavior. If this is the case, is it thenimpossible to advance the scientific study of these rituals beyonda mere description of them?My answer is 'no,' because in many cases the Lionese agriculturalrituals can be interpreted relevantly. Therefore wecan proceed from simple description to a fairly detailed interpretationof these rituals. The aim of this study is to describe theLionese agricultural rituals in detail and to investigate the culturalrepresentation of agricultural rituals (i.e. interpretations devisedby the Lionese themselves concerning their agricultural rituals)by means of the concept of relevance developed by Dan Sperberand Deirdre Wilson [SPERBER and WILSON 1986].After the exposition of a theoretical framework in the introductionof this study, three sections follow. In section one,there is undertaken a description and analysis of the knowledgeand beliefs concerning social organization, crops, deities, and thesettings for these agricultural rituals such as the ceremonial house,the village and the garden. These will furnish the backgroundknowledge or 'context' for interpreting the agricultural rituals.In section two, an exhaustive description is presented of allthe agricultural rituals, together with the agricultural practice,seasonal changes in natural phenomena, and the annual cycleof 'seasonal beliefs,' such as the visitation of moro nggele (mysterioushead hunters from overseas) and mitleik e (dreadful witchesfrom the east end of Flores), the coming of balu re' e (season ofdisease and death), and the occurrence of tana watu gaka (MotherEarth crying for the golden treasure kept in the ceremonialhouse).In part one of section three, by amplifying the discussionof section one, the agricultural rituals are interpreted by meansof investigating the contexts that make them relevant. Accordingto the cultural representation of the agricultural rituals thatemerges from this investigation, the crops are the wives given to(male) human beings from Mother Earth and Father Heaven,while the agricultural cycle is the life cycle of the daughters ofthese deities. In the next part of this section, it is shown thatthe seasonal beliefs are a set of images implied by the culturalrepresentation of the agricultural rituals.In parts three and four of section three, the followingproblems are discussed.The people of Tana Lise are not given equal status in thecultural representation of the agricultural rituals. Or, more correctly,through participating in the agricultural rituals, they aredifferentiated into chiefs near to the deities and those far fromthem.Tana Lise is subdivided into a number of semi-autonomoussubdomains (maki) ruled by a chief. The chief, as the personnear to the deities in each maki, exercises various powers, andsome of these chiefs do the same thing at the domain level.Accordingly, the rules of agricultural rituals (i.e. the ruleswhich the people obey when performing the agricultural rituals)or the agricultural rituals themselves as rule-following behavior,work in the same way as the 'power-conferring rules' or the'secondary rules' defined by H. L. A. Hart [HART 1961].Finally, in the conclusion of this study, a brief discussioncenters on the reason why the Lionese people restrict their commentsto the rules of the agricultural rituals and are silent on thecultural representation of the agricultural rituals. As Ivo Streckerpointed out, no anthropological theory has so far answeredthis problem satisfactorily [STRECKER 1988:203].In my view, it is important to recognize that the Lioneseagricultural rituals are rule-following behavior in order to understandthis problem. The rules of these agricultural ritualsare simply accepted by the people holding to an 'internal pointof view' (the viewpoint of 'the group which accepts and uses rulesas guides to conduct' [HART 1961:86]). I suggest as a possiblehypothesis that their silence on the cultural representation of theiragricultural rituals is derived from holding to an internal pointof view, and maintaining silence on the cultural representationof them has the effect of making the rules of these agriculturalrituals function in the same way as the 'representations in quotes'defined by Sperber [SPERBER 1975:99-106].
