  • Explosive bolts are reliable and efficient mechanical fastening devices having the special feature of a built-in release. The disadvantage of explosive bolt lies in that it is based on the high explosive effect of a pyrotechnic charge. The aim of the present work is to propose a pyrotechnically releasable mechanical linking device for two mechanical elements that does not suffer from such drawbacks. The pyro-lock using the pressure cartridge has the release characteristic without fragmentation and minimum pyro-shock. The present work is focused on the design, the interpretation of structure, the separation mechanism, separation force, and the results of various tests.

  • The purposes of this study were to : a) examine the current foodservice management practices of twenty-one seniors centers in charge of hoke-delivered meal programs, b) evaluate the attitudes of one hundred and ten recipients of meal service program, and c) provide feedback for the efficient and effective foodservice management for the elderly. Statistical data analysis was completed using the SAS package program for descriptive analysis, T-test, and ANOVA. The results of quantitative analysis indicated that the costs of meals, containers and special foods were mostly dependent on the support from local government(Seoul city). The centers where the volunteers were over seventy five p ercent of the workers were frtty-eight percent and sixty-seven percent of the subjects in food preparation and food delivery to the homebound clients, respectively. Meal preparation and food purchasing were mainly practiced by social welfare worker. Standardized recipes were not developed and meal preparation was controlled under the cook' and volunteers' experiences. The survey results of recipients who participated the home-delivered meals program showed that the mean of meal satisfaction score was rated over three point five in the five-point scale. There were significant differences between dependent variables(volunteer's kindness, plate waste, menu variety) and independent variables(sex, receiving periods and family type of the subjects).

  • The purpose of this study has its meaning to indicate the direction on collection and preservation of national literature which is one of the must important functions of the Central National Library. The Central National Library is, however, a representative library of our country and collect every kind of literature and to meet the requests of its users, the present situation of The Central National Library can't be performed sufficiently on these actions. According to studies of this paper, it have suggested the following five methods as a method of collecting national literature. First, the method by registering copyright endowing the number of copyright like ISBN. Second, the method a n.0, pplied by revising and su n.0, pplementing present legal deposit system. Thirdly, the method that the central one institution secure national budget collect literature of nation i.e., central intensive collection one. Fouthly , method of collecting literature by partial charge through local library networks. Fifthly, method by subject intensive collecting. As the preserving method of national literature, this research has indicated the following two ways. First, to keep the literatures forever, the method of The Central National Library keeps records as a limited volume. Second, The method of dispersing records as the local libraries. To put these methods into practice, it must be preceded that not only national helps, budget secures are needed but special committee must be organized to keep and preserve national literatures and material range also be extended and bibliographies for information data issuing must be worked out.

  • As of 2016, the cremation rates in the capital area are 91.2% in Incheon Metropolitan City, 87.5% in Seoul Special City, and 87.1% in Gyeonggi-do Province, of which Incheon has the highest rate, and cremation of general corpses through the online cremation reservation service of the funeral information system is continuously increasing every year. And as of 2017, the ratio of the cremation for those outside the jurisdiction (residents of other regions) among the users of public cremation establishment in Incheon, is about 32%. As the supply capacity is expected to reach the limit within several years due to the increase in demand for such a cremation facility, I would like to suggest a policy as follows. The expansion of cremation supply capacity by increasing the number of operations in the cremation furnace; The attractions of operating funds through contracts for joint use of the cremation facility with other local governments and investment funds for the expansion of cremation facilities; The plan for controlling the demand in cremation such as an increase in cremation charge for those outside the jurisdiction(residents of other regions), should be considered.

  • Lots of audience turn their eyes upon musical to satisfy various cultural desire. It is popular culture that was watched in culture contents industry. The stage costume which turn audience's eyes in musical the most is the sight art of stage to express visually actor(actress)'s personality, mental state, administrative position, age and the distinction of sex. This study researches designed stage costume which was based on time backgrounds and historical facts of reinvented clothes and its ornaments in Egypt by 'Sonia Rykiel' through musical, 'ten commandments' with special times. We collected home and abroad documentary records, Internet data. Moreover we viewed performance to analyze stage costume and brochure photograph data to study. In consequence the stage costume of musical 'ten commandments' found its way out of traditional clothes and its ornaments largely. We can recognize the stage costume as the most important part in drama by explaining the content on drama as costume through reinvented shape with modern sense and by taking charge of the principal part to lead atmosphere. In addition, thanks to the creative work of designer for stage costume, we can realize important intermediation to make higher artistic value of musical.

  • Antimicrobial peptides (AMPs) have been isolated and characterized from tissues and organisms representing virtually every kingdom and phylum. Their amino acid composition, amphipathicity, cationic charge, and size allow them to attach to and insert into membrane bilayers to form pores by 'barrel-stave', 'carpet' or 'toroidal-pore' mechanisms. Although these models are helpful for defining mechanisms of AMP activity, their relevance to resolving how peptides damage and kill microorganisms still needs to be clarified. Moreover, many AMPs employ sophisticated and dynamic mechanisms of action to carry out their likely roles in antimicrobial host defense. Recently, it has been speculated that transmembrane pore formation is not the only mechanism of microbial killing by AMPs. In fact, several observations suggest that translocated AMPs can alter cytoplasmic membrane septum formation, reduce cell-wall, nucleic acid, and protein synthesis, and inhibit enzymatic activity. In this review, we present the structures of several AMPs as well as models of how AMPs induce pore formation. AMPs have received special attention as a possible alternative way to combat antibiotic-resistant bacterial strains. It may be possible to design synthetic AMPs with enhanced activity for microbial cells, especially those with antibiotic resistance, as well as synergistic effects with conventional antibiotic agents that lack cytotoxic or hemolytic activity.
