  • This paper deals with the standard logic symbols with which the engineer will design the control strategy and loop for the utility boiler of the next generation thermal power plant For this purpose, we review the existing international standards for logic symbols. which include ISO, ANSI, and older SAMA. From this review, it is possible to design the standard logic symbol that will be used in the following design phase. The designed standard logic symbols are supposed to provide the logic design with independence from the specific hardware that will be employed in the phase of construction.

  • Well known and widely used in urban area and limited installation condition, a low noise and vibration piling method which has being called Bored Prefabricated Piling Method was reviewed in terms of design guide, and introduced a few case as well. Among the areas being applied of that method, a structural guide of architectural foundation was reviewed and compared to civil engineering foundation area to provide wider information for the foundation engineers. With introducing a few case application including pile load testing review especially dynamic testing in normal building foundation work, engineers may have a useful information on the design and construction of the piling method even different engineering area. It may also make enhancement a view of foundation engineering knowledge to various pile foundation area.

  • This paper summarizes available literature on the optimization of reinforced concrete (RC) beams. The objective of optimization (e.g. minimum cost or weight), the design variables and the constraints considered by different studies vary widely and therefore, different optimization methods have been employed to provide the optimal design of RC beams, whether as isolated structural components or as part of a structural frame. The review of literature suggests that nonlinear deterministic approaches can be efficiently employed to provide optimal design of RC beams, given the small number of variables. This paper also presents spreadsheet implementation of cost optimization of RC beams in the familiar MS Excel environment to illustrate the efficiency of the exhaustive enumeration method for such small discrete search spaces and to promote its use by engineers and researchers. Furthermore, a sensitivity analysis is performed on the contribution of various design parameters to the variability of the overall cost of RC beams.

  • Purpose: This study aims to investigate how the online review usefulness affect consumers' shopping behavior in non-face-to-face shopping, which is now very common format of shopping environment after COVID-19 pandemic. Factors influencing online reviews were determined as quantity of review, agreement of review and characteristic of review based on research by existing researchers. Research design, data, and methodology: Customers in their teens to 60s who had experience of checking online reviews and purchasing products were surveyed using a Google questionnaire form from January 15, 2022 to February 19, 2022. To verify the validity and reliability of the research model, confirmatory factor analysis and discriminant validity analysis were conducted. In addition, the causal relationship between factors was verified through path analysis. Results: As a result, quantity of review and agreement of review had a statistically significant effect on review usefulness. However, characteristic of review did not have a statistically significant influence on review usefulness. And review usefulness had a statistically significant effect on attitude and purchase intention. Conclusions: This study investigated the factors affecting usefulness of online reviews and empirically analyzed the effects of online reviews on consumer attitudes and purchase intentions providing practical and theoretical implications for corporate online review management.

  • Purpose: The purpose of this study was to compare similarities and differences in research trends for community health nursing between Korea and Japan. Methods: Comparison was made in terms of research design, data collection and sampling method, and key concepts from community health nursing research by literature review. We analyzed original articles from representative Journals covering community health nursing research from 2004 to 2008. Results: We found that research design was quite different between the two countries. Quantitative research design was dominant in Korea, while qualitative and qualitative research designs were used equally in Japan. In particular, outcome research was found only in Korean papers. Conclusion: Based on the comparison, the following recommendations are suggested related to the strengths and weaknesses of research concepts and methods observed in each country. It is suggested that future collaboration should be undertaken especially to improve the diversity of research design and method. More diverse research designs should be used in both countries. Particularly in today‘s aged society, evidence-based research and outcome research are needed for community health nursing in both countries.

  • Since Industry 4.0, there is a growing interest in smart manufacturing across all industries. However, there are few studies on this topic in the garment industry despite the growing interest in implementing smart manufacturing. This paper presents the feasibility and essential considerations for implementing smart manufacturing in the garment industry. A systematic review analysis was conducted. Studies on garment manufacturing and smart manufacturing were searched separately in the Scopus database. Key technologies for each manufacturing were derived by keyword analysis. Studies on key technologies in each manufacturing were selected; in addition, bibliographic analysis and cluster analysis were conducted to understand the progress of technological development in the garment industry. In garment manufacturing, technology studies are rare as well as locally biased. In addition, there are technological gaps compared to other manufacturing. However, smart manufacturing studies are still in their infancy and the direction of garment manufacturing studies are toward smart manufacturing. More studies are needed to apply the key technologies of smart manufacturing to garment manufacturing. In this case, the progress of technology development, the difference in the industrial environment, and the level of implementation should be considered. Human components should be integrated into smart manufacturing systems in a labor-intensive garment manufacturing process.

  • 제품 성능의 고도화, 구조의 복잡화에 따라서 고객이 요구하는 품질특성도 다양화하고 있다. 따라서 가격, 코스트, 외관, 구조, 기능, 안전성, 신뢰성, 보전성, 사용의 용이성 등을 종합적인 관점에서 검토ㆍ설계하여 생산계획을 세우지 않으면 안 되는데, 한편 기술혁신은 점점 급속히 진척하고 제품개발 기간단축의 필요성에 쫓기고 있다. 제품의 품질은 대부분이 설계시에 만들어지게 되는데, 설계의 초기단계로 넘어가는 시점에서는 평가결과를 종합해서 설계품질의 객관적인 확인을 조직적으로 실시하는 것이 결국은 그 후의 공정단축, 품질 및 코스트 유효성의 확보에 대한 지름길이라고 생각하게 되었다. DR이란 제품의 설계품질 및 그것을 구현하기 위하여 계획된 제조 수송 설치 사용 보전 등의 프로세스에 대해서, 객관적으로 지식을 모아 평가하고 개선점을 제안하며 다음 단계로 나아갈 수 있는 상태에 있다는 것을 확인하는 조직적 활동의 체계라고 할 수 있다. DR의 주된 목적은 설계내용의 검토에 의한 그 자체의 문제점에 대한 해결뿐만 아니라 개발 프로그램 전체의 문제점, 진행상황 등을 모니터함으로써 개발관리를 합리적으로 진척시킨다고 하는 목표도 가지고 있다. 또 이것 이외에도 각 기업의 체질과 상황에 맞춰서 실시되고 있는 DR은 여러 가지의 목표를 가지고 있다.

  • 함정은 다양한 탑재장비들과 함정 플랫폼이 통합되어 성능을 발휘해야 하는 복합 무기체계이면서, 장기간의 획득기간이 소요되고 시제품이 바로 전력화 되어야 하는 특징으로 인해 독자적인 개발프로세스를 적용해 왔다. 그러나 최근 기술의 발전과 탑재장비의 복잡화에 따라 함정 획득 분야에도 시스템공학(SE) 절차의 적용이 필수불가결하게 되었다. 그럼에도 불구하고 함정 설계에서 아직까지 SE 절차는 기존의 절차와 융합되지 못하고 별도의 체계로 관리되고 있는데, SE 절차를 반영한 실질적인 통합 프로세스가 아직 정립되어 있지 않기 때문이다. 다양한 함정에 대해 SE 절차의 적용 및 설계 방법 개선 연구가 수행되었으나 통합 측면에서 성과는 부족하였다. 따라서 함정을 설계할 때 적용할 수 있는 SE 기반 통합 프로세스 연구가 필요하다. 본 논문에서는 기존 기본설계 프로세스와 SE 기반 프로세스의 통합을 통해 잠수함 기본설계 프로세스를 정립하였다. 이를 위해 함정 기본설계와 병행하여 SE 기반의 기술검토인 체계요구조건검토(SRR), 체계기능검토(SFR), 기본설계검토(PDR)을 수행하는 방법론을 제시하였다. 그리고 체계요구사항명세서(SSRS), 체계/부체계규격서(SSS), 체계/부체계설계기술서(SSDD) 등의 요구사항 문서들의 생성 및 관리를 위한 효율적인 프로세스를 연구하였다. 이러한 2가지의 프로세스를 통합하여 개선된 SE 기반 기본설계 프로세스를 구축하였다. 구축된 프로세스의 적용성을 평가하기 위하여 현재 기본설계를 진행중인 잠수함에 적용한 결과를 제시하였다. 이를 통해 잠수함의 효과적인 요구사항 관리, 산출물 작성 및 설계반영이 가능하였고, 요구사항과 추적성을 가진 각각의 산출물은 기본설계 시험평가 자료로도 즉각적으로 활용이 가능함을 확인하였다. 잠수함 이외에도 건조중인 다양한 함정 설계에서도 본 연구의 SE 기반 함정 기본설계 프로세스의 유용성이 기대된다.
