  • Material degradation such as high temperature oxidation of metallic material is a severe problem in energy generation systems or manufacturing industries. The metallic materials are oxidized to form oxide films in high temperature environments. The oxide films act as diffusion barriers of oxygen and metal ions and thereafter decrease oxidation rates of metals. The metal oxidation is, however, accelerated by mechanical fracture and spalling of the oxide films caused by thermal stresses by repetition of temperature change, vibration and by the impact of solid particles. It is therefore very important to investigate mechanical properties and adhesion of oxide films in high temperature environments, as well as the properties in a room temperature environment. The oxidation tests were conducted for Ni and Ni-Co alloy under high temperature corrosive environments. The hardness distributions against the indentation depth from the top surface were examined at room temperature. Dynamic indentation tests were performed on Ni oxide films formed on Ni surfaces at room and high temperature to observe fractures or cracks generated around impact craters. As a result, it was found that the mechanical property as hardness of the oxide films were different between Ni and Ni-Co alloy, and between room and high temperatures, and that the adhesion of Ni oxide films was relatively stronger than that of Co oxide films.

  • This experiment was carried out to investigate the changes of egg qualify during storage in order to find out the proper storage condition. Fresh eggs were stored at cold condition ($5^{\circ}C$, relative humidity ; RH :$65\pm$3%) and room condition($25^{\circ}C$, RH :$40\pm$3%) during 10 weeks and examined microbiological quality, weight loss and interior quality periodically. Weight loss was indicated 17.93% at room condition and 2.56% at cold condition. The pH of egg white and yolk were increased from 7.94 to 9.03(average 13.72%) and from 6.16 to 6.57(average 6.65%) at cold condition and from 7.94 to 9.54(average 20.15%) and from 6.16 to 6.90(average 12.01%) at room condition respectively. But pH of egg white and yolk did not showed significant difference between before molting and after molting. Haugh unit was decreased from 82.0 to <30 at room condition after 3 weeks. The most frequent bacteria isolated were E coli, Staphylococcus leutus, S saprophyticus, Citrobacter freundii, Klebsiella oxytoca, Providencia rettgeri, and Pontoea spp. It was recommended that shelf life of unrefrigerated eggs would not be longer than 21 days at room temperature in summer.

  • The aim of this study is to offer the basic data concerning the architectural characteristics of the recently constructed farmhouses built by the residents’ self-planning after 1987, compared with the standard housing plan, for the desirable farmhouse planning. The 77 farmhouses, scattered in Milyang-gun, Yangsan-gun and Ulsan-gun near Ulsan city, were selected for the field measurement and the data, compared with the 14 standard housing plans, were analysed by the qualitative method. The farmhouses studied here showed average size of 25-pyongs(82.5m2) and took the flat slab type of roof by the masonry construction of the red blicks. The characteristics in planning were \circled1 the Anbang placed adjacent above the living room, \circled2 a pare of double-sliding doers for the Anbang. \circled3 a pare of double-sliding doors between the living room and the yard for the openness of the living room, \circled4 a door between the living room and the kitchen, \circled5 the multiuse-room by the kicthen for supplemental use, and \circled6 the storage space as attics secured indoor. The standard housing plans, different from these of the recently constructed farmhouses, placed emphasis on the separativeness of each space using the one hinged doors. The farmhouses built recently therefore were not affected by the characteristics of the standard housing plans.

  • The purpose of this study is to examine the awareness of apartment residents on their using tendency of community facilities established in apartment complex in order to verify a role that such facilities play in making contributions to lives of apartment dwellers and to analyze their using tendency of the facilities and subsequent problems. The study produced the important findings as follows. First, the level of exchange among residents and their satisfaction were raised high in the apartment complex that offered substantial community facilities. Second, in regard to physical aspect, community activities among dwellers were brisk in the apartment complex where community facilities were organically connected. Third, fitness center, shower room and golf course were excessive in terms of space provided while the space alloted for G.X room, a place used exclusively for class, was insufficient. Fourth, the analysis of using tendency and preference level showed that fitness center, shower room and G.X room were the required facilities. The rooms for using PCs and watching DVDs and the singing room were found to be unnecessary because such facilities were low in the effectiveness when the operating cost was considered.

  • High temperature sodium/sulfur battery(Na/S battery) has good electrochemical properties, but, the battery has some problems such as explosion and corrosion at al. because of using the liquid electrodes at high temperature and production of high corrosion. Room temperature sodium/sulfur batteries (NAS batteries) is developed to resolve of the battery problem. To recently, room temperature sodium/sulfur batteries has higher discharge capacity than its of lithium ion battery, however, cycle life of the battery is shorter. Because, the sulfur electrode and electrolyte have some problem such as polysulfide resolution in electrolyte and reaction of anode material and polysulfide. Cycle life of the battery is improved by decrease of polysulfide resolution in electrolyte and block of reaction between anode material and polysulfide. If room temperature sodium/sulfur batteries (NAS batteries) with low cost and high capacity improves cycle life, the batteries will be commercialized batteries for electric storage, electric vehicle, and mobile electric items.
