  • 이 연구의 목적은 존엄사에 대한 한국 중년층의 인식유형을 파악하고 그 특성을 분석함으로써 존엄사에 대한 제도마련 및 정책을 구성하는데 필요한 기초적인 자료를 제공하고자 하는 것이다. 존엄사에 관한 30개의 진술문을 가지고, 32명의 중년층을 대상으로 Q 분류를 하였다. 분석결과 존엄사에 대한 주관적인 인식유형과 그 특성은 허용형, 반대형, 제한적 허용형으로 나타났다. 허용형은 환자의 자기결정권에 의한 존엄사는 수용되어야 하며, 극심한 고통을 동반하는 환자에게 존엄사는 필요하다고 생각한다. 반대형은 존엄사가 허용되면 부당하게 죽음을 맞이하는 이들이 늘어나며, 인간의 생명경시 풍조가 만연해질 것이라고 생각한다. 제한적 허용형은 존엄사를 허용하기에 앞서 구체적인 법과 제도가 마련되어야 한다고 생각한다. 존엄사라는 주제 자체가 국민들의 온전한 합의를 이끌어낼 수 없는 것일 수 있지만, 존엄사제도 추진과정에서 국민의 의견이 반영되어야 할 것이다.

  • Generation Expansion Planning (GEP) is one of the most important decision-making activities in electric utilities. Least-cost GEP is to determine the minimum-cost capacity addition plan (i.e., the type and number of candidate plants) that meets forecasted demand within a pre specified reliability criterion over a planning horizon. In this paper, Differential Evolution (DE), and Opposition-based Differential Evolution (ODE) algorithms have been applied to the GEP problem. The original GEP problem has been modified by incorporating Virtual Mapping Procedure (VMP). The GEP problem of a synthetic test systems for 6-year, 14-year and 24-year planning horizons having five types of candidate units have been considered. The results have been compared with Dynamic Programming (DP) method. The ODE performs well and converges faster than DE.

  • Common-mode voltage (CMV) causes overvoltage stress to winding insulation and damages AC motors. CMV with high dv/dt causes leakage currents, which create noise problems for equipment installed near the converter. This study proposes a new pulse-width modulation (PWM) strategy for three-level T-type NPC inverters. This strategy substantially eliminates CMV. The principle for selecting suitable triangle carrier signals for the three-level T-type NPC is described. The proposed method can mitigate the peak value of CMV by 50% compared with the phase disposition pulse-width modulation method. Furthermore, the proposed method exhibits better harmonic spectrum and lower root mean square value for the CMV than those of the reduced-CMV method on the basis of the phase opposition disposition PWM scheme with modulation index higher than 0.5. The proposed modulation can easily be implemented using software without any additional hardware modifications. Both simulation and experimental results demonstrate that the proposed carrier phase-shift PWM method has good output waveform performance and reduces CMV.

  • Hayabusa is the JAXA's space mission that succeeded in sample-return from S-type asteroid (25143) Itokawa. During the rendezvous phase, more than a thousand of images were taken with the Asteroid Multi-band Imaging Camera (AMICA). It is valuable to study the regional variation of the optical properties on the asteroid using these images to know the generality and uniqueness of the returned samples. In addition, AMICA images are important in that they provide unique data set at low phase angle (i.e Sun-Itokawa-AMICA's angle) that have not been explored in the previous asteroidal missions. At the previous conference (2015 KAS spring meeting), we introduced our preliminary data analysis of AMICA data without considering the shape model of Itokawa and mentioned. In this study, we present a new result obtained through further analysis, taking account of the shape model of the asteroid. We thus utilized "plate_renderer" tool to derive Hapke model parameters at different terrains. It is found that the opposition amplitude (parameter B0) is consistent with those of the other S-type asteroids while the opposition width (parameter h) is significantly narrower than those of the other S-type asteroids. At this conference, we plan to describe the regional variation of photometric properties on Itokawa.

  • A historical investigation reveals that English preposition with underwent a change from OPPOSITION to ASSOCIATION and further to ACCOMPANIMENT, where the first stage shows peculiarity in that the two concepts involved comprise an unusual set to form an extensional chain. Intrigued by this oddity, this paper aims to investigate the semantic structure of English preposition with from a grammaticalization perspective. We review mechanisms and models of semantic change and evaluate their adequacy with the semantic structure and change shown by with. Drawing upon the observed fact that with underwent the apparent antonymic semantic change, it is argued that such semantic change mechanisms as metaphor, metonymy, subjectification, and generalization have difficulties explaining the change, and that only the Frame-of-Focus Variation can effectively account for this peculiar change type. In terms of semantic change models, we argue that the Bleaching Model cannot effectively provide an explanation; that the Loss and Gain Model has problems in explaining the motivation of change directions; that the Metonymic-Metaphoric Model cannot be assessed at the current level of investigation; and that the Overlap Model and the Prototype Extension Model excellently account for the macro-level changes.

  • In the Sci-Fi movie, with future scene in its setting, how images are shown in the film is very important. Sci-Fi movie is supposed to be expressed In different way of its set design. This study suggests various types of expression in Sci-Fi movies. Sci-Fi movies construct the narrative upon the binary opposition of nature vs. culture, human vs. nonhuman. Sci-Fi movie is a contested terrain where conservative, liberal and radical ideologies are competing. While liberal Sci-Fi movies consider the opposition compatible, conservative texts show the paranoid towards science and nonhumans. And, Sci-Fi movies are expressed as utopian and dystopian. Utopian and dystopian elements are found in the history of architecture. Utopian element is often found in the religious architecture, and those buildings are geometric, orderly, and gorgeous. Dystopian element is often found in modern architecture, and those are asymmetric, distorted, and incompleted. Conservative movie, which developing of science is expressed negatively, retains both utopian and dystopian elements evenly. Liberal movie, such as Space Opera which science is expressed positively, is changed from futurist and mechanical type into more simple, geometric and orderly shrine type. Radical movie, which the boundary of human and science is expressed darkly, retains dark, complex, and incomplete dystopian expression elements.

  • In this paper, factors affecting intra-organizational diffusion of Big Data systems from the perspective of the Big Data system vendors have been analyzed. In particular, the theory of resistance against innovation that exists in some form before the adoption or rejection of innovation has been focused on. In order to do that, the resistance has been divided into three categories : postponement, rejection and opposition. The variables affecting each type are also divided into four independent variables : perceived risk, innovation characteristics, user attributes, and organizational attributes. As a result of the survey, it was confirmed that the influences of each variable are different according to the type of resistance. As the strength of the resistance was increased, the influence of the trialability was increased as well. As the strength of the resistance was decreased, the satisfaction with the existing system became more influential on the resistance. The time risk and the satisfaction with the existing system were found to affect all types of resistance. From the vendor's point of view, strategic implications are presented in terms of marketing or system development for diffusion, depending on the degree of resistance of the adopter.

  • Objectives: The study investigated health professionals working in the metropolitan area and Jeolla-bukdo, South Korea, from April 30 to May 17, 2017 to understand their views on the issue of including dental hygienists in the scope of medical personnel of South Korea. Methods:A total of 270 surveys were analyzed in this study. The survey consists of 5 questions on general issues; 10 on the awareness of present work of dental hygienist; and 1 on opposition or approval about including dental hygienist in medical personnel. The collected data were analyzed using SPSS for Windows 18.0, as well as frequency analysis, cross analysis and logistic regression analysis. Statistical significance level (${\alpha}$) is 0.05. Results: 1. Broken down by gender, male subjects showed more oppositions against including dental hygienists in the category of medical personnel while female subjects showed more favorable opinions (p<0.05). In terms of academic background, those who had graduated from graduate school or higher showed a higher propensity for opposition while those who had graduated from a 3-year college showed a higher tendency for approval on the idea (p<0.05), In terms of occupational type, health professionals showed more opposing views whereas medical technologists showed more approvals than others (p<0.001). 2. With respect to the awareness of work specialty and proficiency of dental hygienist according to general characteristics, the higher the age, the higher the awareness level was. In terms of the occupational type, medical technologists were found to have higher awareness level than health professionals (p<0.001). 3. With respect to the relationship between general characteristics and view on including dental hygienists in medical personnel, the occupational type of health professional was found to have 6.33 times more oppositions than medical technologists. When the awareness level on proficiency of dental hygienist was low, opposition was 6.52 times more frequent (p<0.05). Conclusions: Based on the findings above, the inclusion of dental hygienists in medical personnel seems necessary in properly establishing the specialty and role of dental hygienist in the dentist medical environment of the country in order to enhance national oral health related preventive dental service and expand the demand. To this end, it is necessary to provide nationwide promotion, work to change the awareness of health professionals in other occupational types, and facilitate public promotion for legal ground establishment.

  • The Opposition Effect (OE) is an enhancement of the brightness of a reflecting light as the phase angle (the Sun-target-observer angle) approaches zero. The mechanisms have been studied both theoretically and experimentally and nowadays recognized that there are two major mechanisms, namely, coherent backscattering OE (CBOE) and shadow hiding OE (SHOE). From data analyses of an S-type asteroid Itokawa taken with the Hayabusa spacecraft onboard camera, it is suggested that the CBOE would be dominant at phase angle smaller than ~ 1.4 deg, while SHOE dominates at larger phase angles (M. Lee & M. Ishiguro, under review). The study on the physical parameters which affect the OE, such as size and composition, will lead us to find a way to disentangle each of them from observation. The experiments in lab, however, faces two major difficulties: (a) the detector blocks the incident light if phase angle is nearly zero and (b) incident and emission angles must be controlled with high angular resolution to prevent blurring of OEs at different phase angles in one measurement. In this presentation, we introduce a new apparatus which has been installed at Seoul National University to investigate the OE in our lab, and summarize the initial results. It will be a valuable starting point to establish infrastructure in Korea, and will shed light on the investigation of OE physics using laboratory simulants.

  • In recent years, various studies about 'Biomorphic design' have been conducted and accelerated among many recent design concepts and methodology. Therefore, this study classifies the types of biomorphic fashion design based on literature review, and select biomorphic fashion designs in the latest fashion designer's collection. This study aimed to determine the types and characteristics of the biomorphic design in fashion design, and analyze the characteristics and the interpreted intrinsic meanings through Greimas Semiotic rectangle model based on the Binary-Opposition of meaning and Isotophy. As the result of analysis, biomorphic designs in fashion are classified as three types: 'representational imitation of form', 'technical imitation of functional features', and 'imitation of symbolic attribute'. 'Representational imitation of form' was derived from an organic design through atypical forms, repetition and extension of figurative forms of nature, and 'the functionalities of the nature' are interpreted as the feature to maintain the condition of the life itself and to attempt to regulate the status of self-autonomy. Lastly, 'the imitation of symbolic attributes' is designing the process of creation, growth, expansion and destruction from circulation of nature.
