  • This paper presents a conceptual approach to convert customer requirements expressed in ordinary language into a form of qualitative and quantitative functions for developing new products. This approach attempts to combine the concepts of the value engineering and the Kansei engineering. It emphasizes that customer require- ments should be interpreted and reflected on the design of new product. Specific are discussed for extracting subjective requirements and transforming them into qualitative and quantitative functions for product design. This approach is expected to provide the product designer with a systematic efficient tool for incorporating subjective requirements into a product design.

  • Bareboat Charter Register or Dual Registration under a Demise Charter scheme, does not in fact sanc-tion the alternative use of flags of different states, but rather it authorises the use of the flag of the coun-try where the ship is temporarily flagged only. Bareboat Charter Register is not intended to miselead third party states or persons dealing with the ship in respect of its nationality. Bareboat Charter Register gives a shipwner a more flexible and attractive package, for example mortga-ging facilities might be more attractive in one state because of its stronger laws relating to recovery of liens, whereas the manning requirements might be attractive in another state. By using Bareboat Charter Register, a shipwner/manager can avail himself of both advantage instead of settling for a compro-mise. Ships on a Bareboat charter Register would be subject to the safety, manning and anti-pollution require-ments of the second flag state and would carry that state's right to fly a flag of the original state be withd-rawn and the effect is to suspend the registration during the period of demise charter except in so far as relates to Title transactions.

  • With research data generation on the rise, Institutional Repositories (IR) are one of the tools to manage it. However, the variety of data practices across institutions, domains, communities, etc., often requires dedicated studies in order to identify the research data management (RDM) require- ments and mapping them to IR features to support them. In this study, we investigated the data practices for a few national universities in North Macedonia, including 110 participants from different departments. The methodology we adopted to this end enabled us to derive some of the key RDM requirements for a variety of data-related activities. Finally, we mapped these requirements to 6 features that our participants asked for in an IR solution: (1) create (meta)data and documentation, (2) distribute, share, and promote data, (3) provide access control, (4) store, (5) backup, and (6) archive. This list of IR features could prove useful for any university that has not yet established an IR solution.

  • We developed a polyclonal antibody (PAh) based- ELISA system to accurately and rapidly monitor inocula on plant surface before onset of anthracnose. Titer of mouse antisera against conidia of Colletotrichum gloeosporioides was determined by using indirect ELISA. It was high enough to be detectable up to ${\times}$ 12,800 dilutions. Absorbance readings exceeded (1.5even at a 10$^{-5}$ dilution. Sensitivity of PAb was precise enough to detect spore concentration as low as 50 conidia/well by indirect ELISA. PAb1 and PAb2 proved to be very sensitive and highly specific to the target pathogen, C. gloeosporioides, apparently discriminating other unrelated pathogens, or epiphytes. Absorbance values for original isolate exceeded 1.0, but no reaction was detected with other isolates, except three other anthracnose fungi: C. gloeosporioides (pepper strain), Glomerella cingulata (apple strain) and C. lagenarium. Our data suggest that PAb1 and PAb2 bind with the protein epitope that partially contains residues of amino acid, arginine, and Iysine. This kit fulfills the require-ments for detecting inoculums before infection and during onset of anthracnose on sweet persimmon.

  • Information system gradually increases the complexity and scale of the project, while if the project fails to occur. To analyze the causes of failure of the project a lack of understanding of your project, unclear requirements and requirements change, etc. of the software development life cycle from requirements analysis phase is to find the source of most. In this paper, a software development project needs analysis derived from the traceability between features and functionality, and development needs throughout the life cycle requirements during the ongoing change management tool was designed to allow. And among those related to the project through consultation with a sufficient consensus to build a common understanding of effective communication will discuss the features required to support.

  • In this study, it is to verify the applicability for a simplified model(IEC61400-2, Design Require-ments for Small Wind Turbines, 2006-03) is the international standard is used to the structural design. In the design process of a wind turbine, the safety of a designed wind turbine is one of the most important factors. The simplified model can be used to determine the design load for small wind turbines. So, this paper has been re-evaluated a small wind turbine design loads that produced already. As a result, the material characteristic value(Rchar) of Blade, Rotor shaft and the tower are $90E6[N/m^2]$, $441E6[N/m^2]$ and $94E6[N/m^2]$. Therefore, the value of the applied safety factor to each part of the survival probability of 95% are satisfied.

  • Pericarp and seedcoat removal treatments were tested to determine their effectiveness in the hard-to-germinate botanical seeds of jerusalem artichoke. Fresh seed of five Helianthus tuberosus L.varieties were (A)untreated (B)water soaked overnight (C) soaked overnight followed by renoval of pericarp or (D) soaked overnight followed by renoval of pericarp and seedcoat. The results indicate that treatments which removed the pericarp and seedcoat were the very effective, giving germination of over 90%. A considerable increase in germination did not follow only the peri-carp removal treatments. The factors inhibitory to germination of fresh jerusalem artichoke seed is associated withthe seedcoat. The removal treatment of pericarp and seed-cost is recommended despite its complexity because it givesa high germination percentage and varies least from varietyto variety. Heliarthus tuberosus L., a biomass potential crop, is a member of the family compositae. The genus Helianthushas provided man with two food plants, the sunflower (H.annus) and the jerusalem artichoke or topinambour (H. tube-rosus) . (3) The jerusalem artichoke grown for its tubers, has always been an extremely minor crop, but it is stillgrown in many places as a food for man or livestock and forthe production of alcohoL. Though tubers are used for pro-pagation jerusalem artichoke also flower and produce seedin head-like in florescences. Flowers are developed acro-petaLly on flattened receptacles such that outermost flowers are oldest. Each of these epigynous flowers may develop an achene-type fruit in which outer layers of the overy wallpersist, while inner layers become disorganized. Insidethe ovary wall of mature fruit, there is a papery seedcoat, probably composed of compact cells from endosperm, integu-ments, and nucellus.In general, the efforts to improving this crop havebeen hampered by the hard-to-germinate botanical seed.Seeds did not germinate for at least IL months after harvest.Fresh seeds of some varieties require one year more to gar-minate. (5) Since the time factor between generations isof concern in a prospective breeding program of jerusalemartichoke , these observations led to investigation of thenature of delayed seed germination in jerusalem artichokeas a biomass potential crop.

  • There are various methods to trace output in software development to verify the consistency and completeness of requirements. Existing studies do present the trace meta-model or automated tools, but fail to list specifically traced output or traced items. Also, in regards to trace tables, which contain traced items, existing studies don‘t consider the whole software development process but merely its sub-process. Given this, the present study suggests an extended requirements tracetable that tracks output from the inception of the project through the architectural design phase to the application delivery, following up on the researcher’s previous study on a tracetable that considered only a sub-process of the whole development process. In addition, in order to address the problem of the tracking process becoming complicated with increased tracefields due to an extended trace table, the researcher suggests a method for normalizing a requirements tracetable that can integrate and separate by development process phase. Apply it to theH system development project of a D company, and this study caseverified application possibility of study, confirmed an effect of a chase to easily find out an error of requirements. Improve precision of a traceto verify consistency of requirements and completeness through this study, and will minimize failure of a software development.
