  • Mezzanine products are financial investment products with both bond and stock characteristics, which are mainly issued by low-grade companies in the financial market to secure liquidity. Therefore, bondholders investing in mezzanine products must make decisions about when they want to convert to stocks, along with whether they invest in mezzanine products issued by the company. Therefore, in this paper, a total of 2,000 learning data and 200 predictive experimental data with stock conversion events completed by major industries are divided, and mezzanine event algorithms are designed and performance analyzed through artificial neural network models. This topic is meaningful in that it proposed a methodology to scientifically solve the difficulties of exercising mezzanine products, which are of high interest in the financial field, by applying artificial neural network technology.

  • This paper applies a structural technique with uniform parallel switch characteristics in gates and power loops to minimize the ringing and current imbalance that occurs when a general discrete package (TO-247)-based power semiconductor device is operated in parallel. Also, this propose a heat sink integrated switching module with heat sink design flexibility and high power density. The developed heat dissipation-integrated switching module verifies the symmetry of the parasitic inductance of the parallel switch through Q3D by ansys and the validity of the structural technique of the parallel switch using the LLC resonant converter experiment operating at a rated capacity of 7.5 kW.

  • The aims of this study are to analyze the current states and problems of development finance in the regional development projects, and to examine new sources and techniques of development finance for activating regional development projects. Analyzing the current states of development finance in regional development project, the problems such as the poorness of development function, the low accessibility to formal financial market, especially capital market, and the dominant use of corporate financing can be seen. In these context, four alternatives are proposed in order to activate development finance. First alternative is to use the funds which invest the equity of real estate, such as REITs. The second is to activate project financing. The third is to use asset backed securities. The forth is using mezzanine capitals as the means of protecting investors.

  • Except the time when relics of a museum are exhibited or loaned to the public, they are stored in a storage. In addition, it is common view that collections are exhibited a few of total stored collections in a museum. Therefore, the environmental condition of a storage is an important factor. Hereby, the purpose of this study is to suggest the design guidelines of a storage for conservation of relics in a museum. The results from this study are as follows briefly. First, location of storages has to be located and centralized above ground against preservation environment and additional renovation. Second, for storage size, It is reasonable to secure long-term experimental data after planning about 20% of whole section in present domestic situation. Third, in order to prevent environmental deterioration due to short storage floor space, adequate storage height has to be secured against a mezzanine deck and spare storages need to be planned. Where a mezzanine deck is designed, detailed plans have to be supported for equal micro climate in a storage. Fourth, in respect of environmental control of storages, finish materials with adjustment ability on relative humidity have to be used after the system is installed jointly direct and indirect way by air chamber, considering domestic condition for management of intermittent ventilation.

  • The purpose of this study is to provide the guidelines for the planning and design of officetels, meeting the requirements of life in one-person household which is a new type in housing market. Literature survey is used as a research method. We analyzed the needs of officetel residents, by reviewing researches and by examining internet homepages and catalogs of 20 officetels sold since 2000. Case study analysis method is used as a qualitative analysis. The major findings of this study are as follows; 1) In dwelling unit space, it lacks the independence of working space and the privacy of living space. Therefore, the provision of various unit plans, such as 2-bay plan, unit with mezzanine floor or movable walls, layout of kitchen and dining area in window side, is proposed. 2) In communal space, it lacks the consideration of natural environments and the systematic maintenance. Therefore, the introduction of communal workshop and conference rooms and of various types of garden space, is proposed.

  • The aim of the present contribution is to consider and underline the essential interactions among the historical knowledge, the seismic vulnerability assessment, the investigation experimental tools, the preservation of the architectural quality and the strengthening design in regard to architectural heritage conservation. These topics are argued in relation to Palazzo Murena in Perugia, designed in the eighteenth century by the famous Architect Luigi Vanvitelli, and currently headquarters of the city's University. Based on the surveys and the visual inspections, a preliminary a priori global analysis has been performed by means of the FME method. The obtained results permitted to plan an experimental tests campaign inclusive of structural health monitoring. The new achieved "knowledge" of the building allowed to refine the seismic safety assessment. In particular it was highlighted that the "mezzanine floor" can be a vulnerable element of the building with the collapse of its masonry walls. Preserving the architectural characteristics, a local reinforcement intervention is proposed for the above-mentioned level; this consists of the application of plaster with FRCM, assuring an adequate strength, without burden the masonry structure with additional weight, and therefore a decreasing of the seismic vulnerability. The necessity to consider, in this ongoing research, other local mechanisms is highlighted in the unfolding of the last part of work.

  • The purpose of this study is to propose the unit plan for home office which can substitute the existing unvaried unit plan in housing and homogeneous working space in office building through the recognition of necessity and possibility about whether home-basedworkandhomeofficecanbeformedornot. Based on the above contents of a research, the following conclusions were summarized; 1. The unit plan of home office was divided into 'jointly-used type' and 'independent-separated type' in accordance with the relationship between housing and working space, 'dwelling-emphasis type' and 'working-emphasis type' in accordance with the grade of ranks between housing and working space. And the universal validity which could accept properly the dweller's characteristics was drawn by the above classification of unit types. 2. The required characteristics in a unit plan for home office were classified into flexibility, privacy, efficiency, identity, amenity. And the analyzing system of planning methodology was assigned according to dividing interior components into space-functional, space-designing interior facts. The planning methodology would have to be considered on the correlation with each required characteristic. As a result of the study, through a planning of independent-separated type, In especial, 'vertical-separated type', it was certificated that vertical-separated type could satisfy a variety of required characteristic in space-designing as well as space-functional aspect.

  • I examine the relationship between values and security designs of MBS(mortgage-backed securities), using four different types of them. To this end I consider a pass-through and three different kinds of CMOs(collateralized mortgage obligations). It turns out that the pass-through has the lowest value and that, among CMOs, that of a senior-mezzanine-subordinate design has the highest value. This implies that CMOs of a simple and extreme design, like that of a senior-subordinate design, are not likely to be the best CMOs for risk averse buyers. Another critical finding is that the optimal security design of CMOs or MBS does exist in the form of an interior solution. This indicates that MBS issuers could charge higher prices of MBS given their underlying mortgages by tailoring MBS security designs to the needs or utilities of MBS buyers, usually by removing and combining risks of component tranches of MBS. Accordingly a thorough study of realistic utility functions of MBA buyers could enhance the values or prices of MBS to be issued.
