  • This paper introduces a systems engineering approach to reliability centered maintenance to address some of the weaknesses. Reliability centered maintenance is a systematic, disciplined process that produces an efficient equipment management strategy to reduce the probability of failure [1]. The study identifies the need for RCM, requirements analysis, design for RCM implementation. Value modeling is used to evaluate the value measures of RCM. The system boundary for the study has been selected as containment spray pump and its motor drive. Failure Mode and Criticality Effects analysis is applied to evaluate the failure modes while the logic tree diagram used to determine the optimum maintenance strategy. It is concluded that condition based maintenance tasks should be enhanced to reduce component degradation and thus improve reliability and availability of the component. It is recommended to apply time directed tasks to age related failures and failure finding tasks to hidden failures.

  • 21st century has different characters from 20th century which was an era of machine and rationality based on the industrial revolution. With the advent of the digital revolution, it became an era of pluralism, culture, and emotion. The digital technology made it possible to connect the whole world together in real time and brought about the entirely new notion of time and space. It also dramatically altered the world view. Now we have a different set of social and cultural values from the past. This paper researched the influences of these social and cultural changes on public designs. The leading trends of public designs were analyzed and the successful cases were studied. The main research methodologies were the document review and the instrumental case study. The major social & cultural paradigms of a present era were classified as 'pluralism', 'digital & information revolution', 'human-centered value (against machine-centered value of 20th century)', and 'organic world view'. Each of the classified paradigms was analyzed more to find out the influences on the various trends of public designs. 'Pluralism' has influence on 'experiential public design', 'community art', and 'public design of local values'. 'Digital & information revolution' has influence on 'content-centered public design', 'smart public design', 'immaterial public design', and 'performance in public design'. 'Human-centered value' has influence on 'universal design approach in public design', and 'emotional public design'. 'Organic world view' has influence on 'sustainable public design', and 'ecological public design'.

  • We propose a modified mid P-value method to reduce the conservativeness for the inference of conditional associations in three-way contingency tables. This improves the ordinary mfd P-value method. For $2{\times} 2${\times} K$ tables, we propose confidence intervals for an assumed common odds ratio based on inverting two separate one-sided tests using the modified mid P-value. Also, an alternative and usually even better ways of constructing intervals, based on Inverting a two-sided test, are presented. The actual probability of coverage of a 100($1-\alpha$)% confidence interval is centered about the nominal level, but the modified mid P-value approach gives actual coverage probability even closer to the nominal level than the ordinary mid P-value approach.

  • The tripartite mission of 'academic medicine' is education, research, and patient care. Academic medical centers (AMCs) are carrying out the mission and ultimately aiming to improve the health of people and communities. Globally, AMCs are facing a tremendous financial risk stemming from the changes in health insurance reimbursement plans and a shortage of human resources. Innovative AMCs in the United States are trying to transform their physician-centered, and siloed structure into a patient-centered, and integrated structure. They are also building integrated systems with primary healthcare groups to provide continuous patient care from primary to tertiary levels and making strategic networks based on value-based payment and the patient-centered model. These changes have been proven to improve outcomes of patient care and increase fiscal revenues, which are both crucial in supporting education and research. To address the shortage of human resources, programs are being built to develop newly appointed faculty for the future. AMCs have different approaches to bringing changes into their organizations; however, there is a common emphasis on 'a patient-centered approach,' which helps them set more explicit organizational values and make strategic decisions based on their values. Korean AMCs are facing similar challenges to AMCs in the United States in spite of many differences between the countries' healthcare systems. The innovative efforts of AMCs in the United States to address the challenges will be helpful, well-worked examples for Korean AMCs with similar challenges.

  • This study was designed to investigate differences in some aspects of value conceptions in fundamentals of nursing functions between nursing service personnel and nurse-educators. The purpose of the study was to identify the difference of value conceptions between the hospital nurses and school instructors, to contribute as a reference in strengthening the educational program in establishing nay hinder professional growth. The questionaries of this study were focused in the following aspects: 1) establishment of nursing service management system, 2) strengthening of the professionalization of nursing service, 3) hindrance in accomplishment of independent nursing functions, 4) communication skills in nurse-patient relationship, 5) activities directly related to nursing care planning, 6) communication skills in nurse-doctor relationship, 7) attitude towards taking responsibilities for patient- centered nursing approach, and 8) nursing educational approach towards preparation of professional competence in practicing independent nursing functions. 265 graduate nurses from 14 general hospitals and 88 nursing instructors from 18 schools, collegiate and diploma, were sampled. The main findings of the study were as follows; 1. Both groups responded highly in the lack of public recognition of nursing profession and hospital administrators support in establishment of nursing service management system. Further investigation is needed to define some relationship between the intrinsic and extrinsic factors which might give influence to the professional development. 2. while hospital nursing personnel responded on environmental pressure such as a heavy nursing load as the factor giving hindrance to independent nursing functions, the nurse educators responded highly on lack of nursing competence of individual nurses. An emphasis should be placed on the development of nursing interaction through professional education. If the professional model is not well established, nursing function will be limited to medical assistance. 3. 3. The patient-centered approach for nurse-patient communication had given positive respond for both group, tut lacks in team concept in problem solving process. There exist a social distance between nurses and other professional co-workers in the hospital hierarchy. 4. It was indicated that, as an intrinsic factor in the development of nursing service and nursing education, building up a philosophical basis is an utmost importance. This question is opened for further and extensive study to clarify whether existence of philosophical absence or philosophical stasis in nursing profession hinders the development.

  • 이 글은 황윤석(1729-1791)을 사례로 삼아 18세기 조선 지식인들에게서 천인관계 문제가 어떻게 변화해 가고 있었는가를 검토하는 데 목표를 둔다. 천인관계 문제는 유학의 변화를 가늠하는 중요한 지표로서, 전통적으로 유학사의 핵심 주제 가운데 하나로 자리 잡아왔다. 황윤석은 주자학의 바탕 위에서 서학(Western Learning)을 수용한 인물이라는 점에서 이 문제를 검토하기 위한 좋은 사례의 하나이다. 황윤석의 학문은 주자학의 범위를 거의 벗어나지 않았지만, 어려서부터 고학(古學)에 심취했고, 이를 바탕으로 서학(西學)에 관심을 가졌다. 이수(理數)는 고학과 서학을 관통하는 핵심 개념으로서, 종래의 선험적이고 신비적인 진리에서 부분적이나마 경험적이고 실용적인 지식을 함축하는 개념으로 확장되었다. 황윤석은 천문 현상에 대한 이해에서 사실중심적 접근법과 가치중심적 접근법을 병행하였다. 서양 천문학은 그로 하여금 사실중심적 접근법의 측면에서 많은 진전을 이루도록 해 주었지만, 그럼에도 불구하고 그는 가치중심적 접근법을 통해 일 월식을 비롯한 천문의 변리(變異)에 대해 재리논적(災異論的) 관점을 유지할 수 있었다. 사실 가치의 이분법은 당시 주자학이 새로운 지식의 유입에 맞서 스스로의 정체성을 고수하기 위한 방법의 하나였다고 할 수 있다. 그것은 '천도(자연) 인사(인간)' 방향의 간섭을 배제하는 것일 뿐, '인사(인간) 천도(자연)' 방향의 관심까지 부정하는 것은 아니었다. 자연의 감계적 기능을 긍정적으로 강조하는 그가 보기에 천인관계론은 여전히 중요한 논제였다.

  • 본 연구는 경제적 가치와 환경가치를 유기적으로 결합시키는 행복경제학적 접근을 적용하여 자연관과 효용의 관계를 비교하고자 한다. 회귀분석을 수행한 결과 다음과 같은 사항을 발견할 수 있었다. 첫째, 본 분석에서는 자연관에 따라 행복함수 형태가 다르다는 것을 실증적으로 확인하였다. '인간중심적 자연관'의 가치체계는 경제가치중심이며 환경, 신뢰와 같은 비 물질가치 요소가 무시할 정도로 낮은 것임을 통계적 유의도를 통하여 알 수 있다. 둘째, '생태중심적 자연관'은 경제를 포함한 환경, 사람신뢰를 동시에 고려하는 중층적 가치체계를 가지고 있다고 할 수 있다. 그들의 가치체계에 따르면 인간의 편의와 경제적 가치에 치우친 행위는 행복극대화 관점에서 합리적이지 않다는 점을 분석 결과에서 알 수 있다.

  • Future-oriented train design should be able to provide highly refined traffic culture and public transportation service by achieving 'higher value addition, sensitization, and humanization' and then securing safety, convenience, and amenity. Therefore, design of FRT, as a means of environment-friendly public transportation, should have new concepts achieving harmony between design and technology. Consequently, when designing interior of trains for public transportation, it should aim for user-centered strategies. This approach is essentially applied to vehicle design and inducement to new concepts by design aesthetics and their verification become requirements for train Interior design, which should be equipped with sensitivity and functional images. Accordingly, a study on the correlation between constituents in order to implement design is essential to design planning and realization of strategies.

  • The Bigyeokjincheolloe (bomb shell), a scientific cultural heritage, has outstanding historical value for sustaining a gunpowder weapon of Joseon. In this study, the bomb shell was modeled through three-dimensional (3D) scanning centered on the external shape and 𝛾-ray radiography-based on the internal shape. In particular, to improve the contrast in the radiographic image, optimization and image processing were performed. After these processes, the thickness of the inner wall (2.5 cm on average) and the positions of the three mold chaplets were clearly revealed. For exhibition purposes, the 3D model of the bomb shell was output to a 3D printer and the output was rendered realistic by coloring. In addition, the internal functional elements, such as Mokgok, fuse, mud, gunpowder, and caltrops, were reproduced through handwork. The results will contribute to the study of digital heritages in two ways. First, the internal and external shapes of the bomb shell were modeled by fusing two different technologies, namely, 3D scanning and 𝛾-ray radiography. Second, the internal shape of the bomb shell was constructed from the original form data and the reproduction was utilized for museum exhibitions. The developed modeling approach will greatly expand the scope of museum exhibitions, from those centered on historical content to those centered on scientific content.

  • 최근에는 증강현실, 가상현실을 활용한 IPTV 등 TV 관련 기술이 빠르게 발전하고 있다. 이러한 새로운 기술은 공급자 중심의 관점을 넘어설 수 있는 좋은 기회를 제공해 준다. 지금까지 많은 교육용 TV 프로그램은 프로그램 제공자의 관점, 즉 제품중심 논리에 중점을 두었기 때문에, 내용 전달 수준을 넘지 못하였다. 따라서 학습자와 TV 프로그램이 협력하여 새로운 가치를 창출하기 위해 프로그램 제공자의 관점을 넘어 가치공동창출이라는 새로운 관점이 요구된다. 이 논문은 가치의 공동창출을 위한 교육용 IPTV 프로그램 설계 세 가지 원칙(교육서비스디자인 원리로서의 서비스중심논리, 교수설계로서의 목적기반시나리오, 기술혁신으로서의 첨단 기술 접목 IPTV)을 제시하였다. 이는 세계적인 감염병으로 인해 비대면 교육을 위해 IPTV를 교육서비스관점에서 설계할 수 있는 새로운 안목을 제공해 줄 수 있을 것이다.
