Recently hydrogen fuel cell buses have been deployed for the public transportations. In order to introduce buses fueled by hydrogen successfully, the research results of hydrogen bus safety should be discussed and investigated significantly. Especially, Korean government drives research in terms of various applications of hydrogen energy to replace the conventional fuel energy resources and to improve the safety evaluation. Thus it is necessary to examine vehicle crashworthiness under side impact loadings. This study was focused on the simulation result evaluation of full bus model and simplified bus model with hydrogen fuel tank module and mounting system located below floor structure due to the significance of bus side impact accidents. The finite element models of hydrogen bus, fuel tank system and side impact moving barrier were set up and simulation results reported model performance and result comparison of two side impact models. Computational results and research discussion showed the conceptual side impact framework to evaluate hydrogen bus crashworthiness.

목적: 본 연구는 암환자를 돌보는 간호사들을 대상으로 간호사의 영성, 죽음불안 및 소진 정도를 확인하고, 세 변수들간의 관계를 파악하고자 한 서술적 조사 연구이다. 방법: 대상자는 서울에 소재하는 일개 암 전문 종합병원에서 근무하는 간호사 210명을 대상으로 하였다. 자료는 2012년 4월부터 6월까지 수집하였으며, 수집한자료는 SPSS 19.0 program을 사용하여 t-test, one-way ANOVA, Scheff'e test, Pearson's correlation coefficient로 분석하였다. 결과: 영성은 6점 만점에 평균 3.51점이었으며, 하위영역별로는 삶의 의미와 목적, 관계성, 내적 자원, 초월성 순으로 높았다. 죽음불안은 5점 만점에 평균 3.22점이었으며, 하위영역별로는 죽음의 부인, 짧은 시간 지각, 죽음에 대한 두려움, 죽음 연관 문제에 대한 두려움 순으로 높았다. 소진 정도는 7점 만점에 평균 4.10점이었으며, 하위영역별로는 정서적 소모, 비 인간화, 개인적 성취감 감소 순으로 높았다. 영성은 죽음불안(r=-0.327, P=0.01)과 소진 정도(r=-0.690, P=0.01)에 역상관관계가 있었으며, 소진은 죽음불안(r=0.550, P=0.01)과 정상관 관계가 있었다. 결론: 본 연구 결과를 바탕으로 간호사들의 영성을 높이고, 그들의 죽음불안과 소진 정도를 낮출 수 있는 영적 중재를 제공하는 것을 제안한다. Purpose: This study is to explore the relationships among spirituality, death anxiety and burnout level of nurses caring for cancer patients. Methods: Participants were 210 nurses from a cancer hospital in Seoul. Data were collected from April until June 2012 and analyzed using t-test, one-way ANOVA, Scheffe's test, and Pearson's correlation coefficient. Results: The mean score for spirituality was 3.51 out of six. Among sub-categories, the one that scored the highest was the purpose and meaning of life, followed by unifying interconnectedness, inner resources and transcendence. The mean score for death anxiety was 3.22, and the sub-categories in the order of high score were denial of death, awareness of the shortness of time, pure death anxiety and fear of matters related to death. For the burnout, the mean was 4.10. Among sub-categories, highest mark was found with emotional exhaustion, followed by depersonalization and personal accomplishment. The spirituality level was negatively correlated with those of death anxiety and burnout. Death anxiety was positively correlated with burnout levels. Nurses with the higher spirituality level also had a higher level of education and experience of spiritual education, believed in the existence of God. In contrast, death anxiety and burnout levels were higher among those with a lower level of education, atheists, and for those who answered that religion has little influence on life. Conclusion: Thus, it is necessary to provide spiritual interventions for nurses who care for cancer patients to develop their spirituality, reduce death anxiety and prevent them from burning out easily.

마태복음의 제자도 연구

김경진(Kim, Kyungjin) 한국복음주의신약학회 2010 신약연구 Vol.9 No.4

The disciples of Jesus in the gospels are depicted as very important figures, though they are a foil to Jesus' earthly ministry. However it is pretty interesting to see that they are described differently in each gospel, although they are same people, doing same things along with Jesus their Master. Thus this article launches to delve deeply into this question, particularly in the gospel of Matthew. It is now generally acknowledged that the disciples in Mark's gospel are described badly, so that they appear as deterrent model who is not to be followed but avoided in the community of Mark's gospel. On the contrary, the disciples in Luke's gospel are depicted positively, so that they function as ideal model whom the christians in the Luke's community should imitate in their way of being followers of Jesus Christ. As for Matthew's gospels, the disciples are introduced neither good nor bad, but just in between, which makes the disciples in Matthew's gospel to be a representative of common christians who are sometimes not only applauded for their good works but also scolded for their unfaithfulness. The features of discipleship in each gospel appear also different; in Mark's gospel it is heroic discipleship that means that the christians in Mark's community should risk their lives in order to keep their faith on the verge of death and suffering. Regarding Luke's gospel it turns out to be ethical discipleship, which means that Luke's contemporaries should take heed of Jesus' admonitions for the sake of the poor and needy in their community. In Matthew's gospel, however, learning or education is regarded as a crucial element of discipleship which dictates that the christians in Matthew's community are supposed to learn ardently Jesus' teachings introduced in 5 volumes of sermon, i.e., the sermon on the mount (chs. 5-7), the sermon in sending them out for evangelism (ch. 10), the sermon of the parables about the kingdom of God (ch. 13), the sermon for church's life(ch. 18), the sermon on eschatology (chs. 24-25). The reason why Matthew accentuated learning as a feature of discipleship is because Matthew's church was expelled out of Jewish synagogues due to their faith in Jesus Christ, so they needed to ascertain their christian identity which they recently acquired as they came to believe Jesus as their Lord and Saviour.

유통 콘셉트 및 소비자의 독특성에 따른 AI 서비스 선호 차이에 관한 연구

김경진 ( Kyungjin Kim ) 한국유통경영학회(구 한국유통정보학회) 2021 유통경영학회지 Vol.24 No.1

Purpose: This study seeks to explore whether artificial intelligence services would be unpopular if the concept or brand image of distribution stores are unique. Research design, data, and methodology: The first study utilizes a 3×2 design. The major variables of Study 1 were consumer need for uniqueness (high vs. low), brand uniqueness (high vs. low), and the service provider (AI vs. human expert). The second study utilizes a 2×2 design. The major variables for Study 2 were the priming concept (uniqueness vs. conformity) and the service provider (AI vs. human doctor). The third study utilizes a 2×2 design. The major variables for Study 3 were the user (self vs. other) and the service provider (AI chatbot vs. film critic). The number of respondents were 278 for Study 1, 164 for Study 2, and 138 for Study 3. Results: In Study 1, respondents with a high need for uniqueness preferred the touch of experts to AI in skin diagnostic services. This pattern was more pronounced in stores with unique brand image, compared to stores with non-unique brand image. The mediation test revealed that the uniqueness-seeking respondents expected experts to better understand and consider their uniqueness than statistical AI. In Study 2, respondents whose concept of uniqueness had been primed trusted doctors more than AI in medical services compared to those whose concept of conformity had been primed. In Study 3, respondents under the “self” category preferred chatting with film critics over AI chatbots in movie recommendations compared to the respondents in the “other” category. Implications: This research suggests that uniqueness can impede AI acceptance in various contexts. Perhaps the reason why AI is spreading slower than expected is not because of technological problems, but rather because of the human fear that individual uniqueness or human character may be lost.

이 연구는 기후 변화에 대응하는 사람들의 예방 행동 의도에 영향을 미칠 수 있는 변인들의 효과에 대해 살펴보고자 하였다. 메시지 프레이밍과 메시지 불확실성 인식이 예방행동 의도에 미치는 영향에 있어서 이슈 관여도와 불확실성 회피 성향에 따른 조절 효과가 존재하는지, 집단적 효능감에 의해 매개되어 예방 행동 의도에 영향을 미치는지, 집단적 효능감의 매개 효과가 이슈 관여도와 불확실성 회피 성향에 의해서 조절되는 효과가 존재하는지에 대해 알아보고자 하였다. 예방 행동 의도는 거시적 차원과 미시적 차원으로 구분하여 분석하였으며, 그 결과 거시적 차원의 행동 의도에 있어서 이슈 관여도와 불확실성 회피 성향이 높을 때 메시지 프레이밍과 메시지 불확실성의 상호작용 효과가 나타났고, 불확실한 메시지가 주어질 때 손실 프레임이 효과적이며 확실한 메시지가 주어질 때 이익 프레임이 효과적이라는 것이 나타났다. 반면 메시지효과와 상관없이 집단적 효능감은 행동 의도에 영향을 미치는 것으로 나타났다. 집단적 효능감의 매개효과가 이슈 관여도와 불확실성 회피 성향에 의해 조절되는지 알아보기 위해 조절된 매개 효과를 검증하고자 하였으며, 불확실한 메시지에 대해 불확실성 회피 성향이 낮을수록 집단적 효능감을 매개하여 거시적 행동 의도에 영향을 미치는 것으로 나타났다. 결론적으로, 기후 변화 이슈와 관련한 설득 효과는 메시지 유형뿐만 아니라 심리적 요인, 개인적 특성을 고려한 다차원적 접근이 필요하다는 것을 확인할 수 있었다. This study aims to examine the effects of message types on preventive behavioral intention with reference to climate change. In this process, moderating effects of issue involvement and uncertainty avoidance, and mediating effects of collective efficacy were tested while moderated mediation effects were considered at the same time. Two message types including message frames (gain-loss frames) and message uncertainty were manipulated in regard to the climate change issue. Experimental samples were divided into four groups by two dimensions (gain/loss framing and high/low uncertainty). The results showed that the micro-level preventive behavioral intention became stronger when involvement and uncertainty avoidance were high respectively. However, in the macro-level behavioral intention, the results indicated the interaction effect between message framing and message uncertainty. The loss frame was more effective than the gain frame when message uncertainty was high, but the gain frame was more effective when message uncertainty was low. Collective efficacy had a significant effect on preventive behavioral intention in a general fashion. To test moderated mediating effects, the moderating variables of involvement and uncertainty avoidance were categorized by high and low group. In the group of the low-level uncertainty avoidance, collective efficacy fully mediated between message uncertainty and preventive behavioral intention. In conclusion, message effects on preventing climate change need to be reinforced by incorporating psychological factors, individual characteristics and cultural specifics. Based on the results, theoretical ramifications and practical applications were discussed.
