The purpose of the study is to explore and understand the product development through the theory of evolution. For the purpose of the study, an evolution mechanism was set up in which the products were applied with. The results showed three distinguishable types of product evolution 'the evolution of functions','the evolution of forms'and 'the evolution of symbols what the products represent'. In order to answer the research questions, , , , the research was carried out in three ways: firstly, some ideas of product evolution were looked closely through existing researches; secondly, the study explored the idea of evolution mechanism being a natural process like an organic system; finally by applying various products with the evolution mechanism, different patterns of product evolution were classified. The results of the study can be summarised as follows: ${\bullet}$ The evolution mechanism in this study can be defined as an 'organic system'that consists of the causes of evolution'(based on the needs and the willingness to have pleasure), 'the point of evolving'(based on a degree of imperfection) and 'the motive of evolution'(based on the readiness to make profit). ${\bullet}$ The evolution mechanism seems to suggest three different patterns in product evolution,'the evolution of functions', 'the evolution of forms' and 'the evolution of symbols'

The KSLV-II project with high difficulties technically requires thorough technical management during long-term life cycle more than 10 years for launching into space. The TRL is a quantitative indicator developed by NASA widely used all over the world to measure technology maturity of a system development objectively and consistently. The TRL is also used to make sure technology level and to establish a future direction in the KSLV-II project. The TRL has advantage enable to identify a technology level through quantitative indicators. However, it takes a lot of efforts such as trials and errors, time and cost to apply it to the project considering the project environments, and stakeholder needs. These include not only to establish TRL management plan from ideal, conceptual and abstractive standards/guidelines such as NASA's, but also to construct TRL management environment enable to apply and manage harmoniously. In the KSLV-II project, it is required to figure out current technology level and technology development trend in the future, to access conveniently, to share related data in real time, and to update periodically for the comprehensive TRL management. From the reason above, the TRL management environment was built by using the systems engineering tool already has been used for other system management data such as requirements in the project. It also could be accomplished a practical management basis of systems engineering from the traceability among system management data including TRL. In this paper, case study results are introduced to manage the TRL for the space launch vehicle using the systems engineering tool in the KSLV-II project.

The nature of school mathematics has not been asked from the epistemological perspective. In this paper, I compare two dominant perspectives of school mathematics: ethnomathematics and didactical transposition theory. Then, I show that there exist some examples from Old Babylonian (OB) mathematics, which is considered as the oldest school mathematics by the recent contextualized anthropological research, cannot be explained by above two perspectives. From this, I argue that the nature of school mathematics needs to be understand from new perspective and its meaning needs to be extended to include students' and teachers' products emergent from the process of teaching and learning. From my investigation about OB school mathematics, I assume that there exist an intrinsic function of school mathematics: Linking scholarly Mathematics(M) and everyday mathematics(m). Based on my assumption, I suggest the chain of ESMPR(Educational Setting for Mathematics Practice and Readiness) and ESMCE(Educational Setting For Mathematical Creativity and Errors) as a mechanism of the function of school mathematics.

The purpose of this study is to examine the effect of the psychiatric nursing simulation practicum, which was developed for the therapeutic relationship forming and communication, psychiatric nursing assessment training utilizing simulated patients, on self-directed learning, learning self-efficacy and learning satisfaction. As a one group pre-test and post-test design, this test conducted 8 hours of intervention on 119 senior nursing students as study subjects. As a result, self-directed learning and learning self-efficacy were seen to be significantly improved after the program compared to before the program, and these variables displayed a moderate-level static correlation with learning satisfaction. These results can be deemed representative of the fact that, concerning psychiatric nursing practicum, a simulation teaching using simulated patients is effective. The results of this study are expected to contribute to improving field-centered psychiatric nursing practicum and the quality of psychiatric clinical work.

The fact that one of the parties to the sale contract has had to pay demurrage to the shipowner under LD clauses in the charterparty does not of itself mean that he can recover that loss from his sale counter party under the sale contract: the route to such recovery is through express clauses in the sale contract itself. LD clauses in a sale contract stand free and independent of their counterparts in the relevant charterparty. LD clauses in a sale contract should be construed and applied as clauses in sale contracts, not as adjuncts to charterparties. Their interpretation should therefore be coloured not by decisions on laytime and demurrage in charterparties, but by their relationship to the contractual duties of CIF and FOB sellers and buyers. The results discussed here have implications for the drafting of LD clauses in sale contracts. If unwelcome surprises are to be avoided, it seems to advisable to start from the principle: what exactly do traders want or need in LD clauses. They need a clause which covers them against charterparty losses where those losses are the result of dealy caused by the counterparty to the sale contract. The parties to the sale contracts are well advised to prepare LD clauses concentrating on that purpose and bearing in mind the followiing questions. First, should the loading and discharge code in the sale contract appear in traders' or trade associations' standard terms and conditions or should they be left to ad hoc negotiation in contract sheets? Second, should that code be as complete as possible, covering loading or discharge periods or rates, demurrage and despatch, or is it enough for only some of those matters to be covered explicitly, leaving other matters to be governed" as per charterparty"? Third, does the introduction or incorporation of a stipulation for the giving of a notice of readiness make the start of laytime more or less predictable as between seller and buyer? Finally should a loading and discharge code in a sale contract actully be called a "laytime and demmurrage clauses"?

The primary aim for using a Korean Condition Based Maintenance (CBM) system is to maintain military operational readiness using Interactive Collection Analysis Systems (ICAS) installed on naval vessels. Other aims are to preemptively provision maintenance and supply functions, to guarantee economical management of logistical assets, and to implement data driven equipment life cycle management. In order to accomplish these aims, it is necessary to establish standard system conditions. However, because manufacturers do not provide the technology necessary for maintenance management, it is required to retain component performance maps for each piece of equipment, and to accumulate data about frequently occurring fault patterns. This study confirms the validity of component performance maps using micro gas turbines and provides accumulated data on machine break downs. This would allow real time equipment performance checks and present performance trends. Then analysis would provide solutions for maintaining the best machine operating conditions with detailed maintenance manuals for operators. This study is a basis for further research to investigate additional ways to develop CBM using data obtained from naval vessels used in actual military operations.
