This study has been performed to come up with any rational way for responding to the functions of fire-fighting spaces newly required by the changing social paradigms and to seek for the approach to designing fire-fighting spaces by taking into account the psychological and behavioral factors of fire-fighters who are exposed stress of operations. In particular, it is to satisfy any physical and functional requirements as special working-spaces and to reflect the psychological and behavioral approach to the workers who are forced to be at standby for a long time, which is the characteristic of their operation, to designing. Accordingly, for fundamental appreciation of whether or not such space programs as space organization needed for operational function are being practiced actively, the fire-fighting headquarters of Incheon City has been selected for the research. First, in the process of assessing the trend of organizing the space at safety centers for the recent 20 years, those built more than 20 years ago were left out from the space selection for the research. Second, those with less than 20 operators also were excluded. Third, among those completed in the same year, only one was selected, which was to avoid overlapping, with the consideration its regional representative nature for applying the safety centers in the jurisdiction of the headquarters equally. The study was performed through the visits to and the actual inspections by surveys at the selected 119 Safety Centers as well as the reviews of literature based on case studies. And for the assessment of significance, surveys and analysis of reliability and factors were carried out. The actual users of Safety Centers were picked as objects for the assessment of significance of space factors at 119 Safety Centers, which revealed that there are five types of dimensions for factor-analyzing standard with which users estimate any significance, which are "Area of Mobilization Preparation and Return" "Area of Standby" "Area of Working Activities" "Area of Employ Welfare" and "Area of Support".

건설공사시 발생하는 환경부하 관리를 위해서는 시공시 실제 투입되는 물량을 면밀히 파악할 필요가 있다. 현재 건설공사에서는 2D도면을 활용한 설계의 경우에는 실제 설계 도서간 물량산출 값의 오차, 설계항목의 누락이 발생하고 있으며 건설 공사의 경우 불확실한 요소들로 인하여 시공 중에도 빈번히 설계변경 및 오류가 발생하고 있다. 또한 2D 설계를 바탕으로 하는 LCA평가의 경우 도면, 내역서 등을 이용하여 작업자가 수기로 작업공종에 투입되는 자재를 산출해야하는 어려움이 있다. 본 연구에서는 2D 설계를 바탕으로한 물량산출과 BIM기반의 물량산출을 바탕으로 LCA 분석을 비교하여 시공과정에서 활용 할 수 있는 신뢰도 높은 환경부하평가 방법을 검증하고자 한다. 또한 설계도서를 활용한 내역기반의 2D설계의 물량산출 및 LCA 평가 방법을 제시하고, 3D 기반의 평가 프로세스를 비교 분석하여 BIM 설계기법 도입에 따른 LCA 평가 활용 가능성을 제시하고자 한다.

유기랭킨사이클의 열역학적 효율에 큰 영향을 미치는 구성요소는 터빈이다. 일반적으로 유기랭킨사이클에서 팽창과정은 작동유체의 급격한 물성치 변화를 수반하므로 터빈의 설계에 많은 어려움이 따른다. 그러므로 효율이 우수한 터빈의 개발을 위해서는 정밀한 터빈의 예비설계가 요구된다. 반경류터빈의 효율은 loading과 flow 계수에 큰 영향을 받으므로 터빈의 예비설계에서 이러한 변수의 선정이 매우 중요하다. 그러나 기존의 성능곡선으로부터 loading과 flow 계수를 선정하는 고전적인 방법을 이용할 경우 정밀한 예비설계를 기대하기 힘들다. 그러므로 본 연구에서는 로터 깃의 개수와 열역학적 설계조건으로부터 loading과 flow 계수를 산출하는 방법을 제시하였다. 본 연구에서 제시한 예비설계모델을 이용하여 예비설계를 수행한 결과는 공신력 있는 상용예비설계프로그램을 이용한 결과와 비교하여 만족스러운 것을 확인하였다. 또한 예비설계모델의 정확성을 검증하기 위해 예비설계한 반경류터빈에 대한 수치해석을 수행하였으며 효율을 제외한 대부분의 변수들이 예비설계조건을 비교적 충족하는 것을 확인하였다.

Purpose: To quantify the effect of the crystallization process on lithium disilicate ceramic crowns that are fabricated using a computer-aided design/computer-aided manufacturing(CAD/CAM) system, and to determine whether they are clinically acceptable by comparing values before and after the crystallization process. Methods: The maxillary first molar was selected as the abutment for the experiments. Ten working models were prepared. Marginal and internal gap of 4 groups of lithium disilicate crowns(n=10) fabricated with conventional method. Comparison was performed using the silicone replica technique and 3D superimposition analysis. The marginal and internal gaps of the restoration were measured before and after the crystallization process of this prosthesis. The average value of each part(the average of values measured before and after the crystallization) was statistically analyzed using paired t-test(α=0.05). Results: The results from the second phase of this research, which compared the average value of the gap between the marginal and internal fits of the lithium disilicate single crown before and after the crystallization process, indicated that the marginal gap was larger and the internal gap was smaller after the crystallization process, and this difference was statistically significant (P<0.05) in all the parts evaluated. Conclusion: While the shrinkage that occurs during crystallization does affect the marginal and internal fit of the prosthesis, it cannot be concluded to be a major effect because the resultant distortion was within the clinically acceptable range.

This study analyzed the process of development and verification of standards through the competency analysis of fashion accessories products in the development of 'National Competency Standards'(NCS), which was carried out in 2013 for the fashion industry. The NCS for fashion accessories production was developed through three Focus Group Interviews (FGIs) and fashion accessories production was defined as "the process of design, development and manufacture intended to produce items that improve the degree of completion of fashion products that are produced from textile fabric, knitted fabric, leather and other materials such as bags, belts, hats, gloves, scarves, neckties and socks with the exception of clothes". The competency unit for fashion accessories production was analyzed in 11 categories: development of design; development of materials; production of prototype samples; calculation of cost; determination of mass production model and price; planning of main manufacture process; ordering of materials; planning for mass production; preparation for mass production; mass production; and inspection of completed products, and the verification was carried out on development outcomes through a survey carried out of on-site personnel. This study recommends the following direction for future improvements based on an analysis of the development process of the NCS for fashion accessories production. First, future development of standards should first provide a rational category system for each area of fashion good production based on the production process, which should be followed by a detailed competency survey. Second, in order to ensure a more efficient verification survey, an expert for each competency unit should be designated for the develop standard to induce a more sincere response. Also the questionnaire should require supplementation in order to collect the various additional opinions of experts of the field. Finally, this study concludes that it is urgent to procure an education infrastructure and specialized professors in order to apply the competency standard for fashion accessories production to the education sector. This study also concludes that the government will be required to provide systematic and consistent support aimed at supplementing development and forming a firm collaborative working environment for the industry and academia in order to improve the current education environment and build a more field-oriented education environment.

국내 게임산업현장에서 게임시스템 기획은 기획자가 게임컨셉을 만족하는 게임플레이가 이루어지는 게임메카닉스 시스템을 데이터구조적 설계방법으로 creative design 작업관점에서 초기적으로 설계하는 작업이다. 그러나 프로그래머는 구현을 위해 기획내용을 바탕으로 게임시스템을 객체지향적 방법으로 engineering design 작업관점에서 설계한다. 이러한 작업방식은 기획자와 프로그래머 사이에 의사소통 과정에서 다양한 오류들과 작업결과물의 미스매칭 오류들의 발생가능성이 높다. 이 문제를 해결하기 위해, 본 논문에서는 기획자가 객체지향적 설계방법으로 게임시스템을 기획하는 방법을 제안하였다. 제안하는 방법은 객체지향적 SW 개발 가이드라인인 GRAPPLE을 기반으로 기획자의 게임시스템 기획에 적합하도록 커스터마이징한 것이다. 본 논문에서 제안한 게임시스템 기획방법의 효용성을 조사하기 위해 국내 게임산업체에 근무하는 게임시스템 기획자 10명을 대상으로 설문조사하였다. 설문 조사결과는 거의 모든 대상자들이 제안한 방법의 효용성이 '조금 이상' 있음으로 나타났다.
