Purpose : The purpose of this study was to identify the extent to which nurses' death perceptions, death anxiety, and stress associated with terminal care affects their attitudes toward terminal care. Method : A total of 214 nurses were asked questions about characteristics, death perceptions, death anxiety, stress associated with end-of-life care, and terminal care attitudes, using structured questionnaires. The data were analyzed using descriptive analysis, t-test, ANOVA, Scheffé's test, Pearson's correlation coefficients, and stepwise multiple regression. Results : Factors influencing terminal care attitudes in participants were positive meaning associated with death, respect for life, final education, end-of-life nursing education experiences, stress associated with end-of-life care, death anxiety, and position. These factors explained 38.7% of variance in participants' terminal care attitudes (F=20.18, p<.001). Conclusion : In order for nurses to have a positive attitude toward terminal care, it is necessary to raise positive awareness about death and respect for life, and it is necessary to develop various educational programs and strengthen their capacity through continuous education.

A bacterial strain, 13-$25^T$ with xylanolytic activity isolated from a single soil sample, was characterized with respect to its phenetic and phylogenetic characteristics. The cells of the isolate are Gram-staining variable rods, but spore formation was not observed. This strain is catalase- and oxidase-positive, and able to degrade starch and xylan. The predominant fatty acids are anteiso-$C_{15:0}$, $C_{16:0}$, and iso-$C_{16:0}$. The major respiratory quinone is menaquinone 7(MK-7), with a polar lipid profile consistent with the genus Cohnella. The DNA G+C content is 54.3 mol%. The 168 rRNA gene sequence analysis indicates that this organism belongs to the genus Cohnella, with Cohnella panacarvi as the closest phylogenetic neighbor. Low levels of 168 rRNA gene sequence similarity (<97.0%) with respect to other taxa with published names and the identification of distinctive phenetic features in the isolate indicate that the strain 13-$25^T$ represents a novel species of the genus Cohnella, for which the name Cohnella damensis sp. novo is proposed. The type strain is 13-$25^T$ (=CCTCC AB $208103^T$=KCTC $13422^T$).

본 총설은 음식윤리의 개요를 식품과학과 산업 분야의 전문인에게 설명하고자 한 것이다. 음식윤리는 음식과 관련된 윤리 또는 윤리적 고려이고, 음식윤리의 핵심어는 생명, 행복, 지혜이다. 음식윤리의 제1원리이자 궁극적인 목적은 인류의 지속가능한 생존이다. 그 목적을 달성하기 위해서는 자연과의 공생, 인간과의 공생, 그리고 음식의 본질적 요소의 충족이 필요하다. 그 필요로부터 생명존중, 자연보전, 속임수나 가짜가 없는 분배의 정의, 소비자 최우선 고려, 절제와 균형, 그리고 안전성 확보의 여섯 가지 정언명령이 산출된다. 정언명령에 상응하는 핵심원리는 생명존중, 환경보전, 정의, 소비자 최우선, 동적 평형, 안전성 최우선이다. 핵심원리 접근법은 윤리문제의 해결에 간단하고 명료하며 실질적인 방법이다. 음식윤리강령 역시 핵심원리를 기반으로 한다.

Respect for human life and respect for human rights are basic values which the organized nursing profession has urged its members to adhere to in their service to human beings. This study was designed and carried out to identify ways to reconcile often conflicting basic values in practice. This study focused on ethical dilema experienced by nurses who were caring for political offenders in prison. Concrete case study was presected to show solutions to the problems.

In this paper, we examine the roles, mutual relationships, and guidelines for a healthy life as exemplified by the characters Santiago and Manolin in Ernest Hemingway's novel "The Old Man and the Sea" and use this content to compare the happy home life of elderly couples in Korea. Through a metaphorical exploration of the lives of elderly husbands and wives in Korean society, the study examines their significance as the core of the family, particularly during their senior years. Ernest Hemingway's "The Old Man and the Sea" portrays Santiago as a unique embodiment of virtue and humanity. As an elderly male fisherman, he symbolizes a profound connection with the sea, as well as qualities such as courage, patience, and unwavering passion. His story underscores the importance of pursuing new goals and maintaining hope even in old age. The relationship between Santiago and Manolin provides insights into the dynamics of elderly husbands and wives in their domestic lives. Manolin's unwavering support for Santiago and his understanding of Santiago's dreams exemplify the significance of mutual support and the establishment of common goals for elderly couples. These characters serve as exemplary models for understanding and supporting one another within a family setting. Within the context of family life, applying these exemplary models and relationship dynamics fosters mutual respect, collaboration, emotional expression, and effective communication. Supporting each other and working towards common goals can enhance the family atmosphere, resolve conflicts, and enrich domestic life. Furthermore, when elderly couples share common goals and enjoy activities together, they strengthen their bond and create a more fulfilling family life. These shared activities deepen the affection between elderly husbands and wives and contribute to a thriving household. Through the characters of Santiago and Manolin in "The Old Man and the Sea," we present in this study a deeper understanding of the values and roles within the domestic lives and affection of elderly husbands and wives. Mutual respect, collaboration, emotional expression, communication, mutual support, common goals, hope, and shared domestic activities all play pivotal roles in maintaining a healthy family life and establishing happiness and well-being within the family. We expect this study to offer valuable insights into the fields of family studies, elderly welfare, and sociology.

The dressing time monitoring in cylindrical grinding is very important with respect to machining efficiency. Therefore, the purpose of this paper is to determine the wheel life by monitoring behavior of grinding power for Wa, 19A and GC. For this purpose, we investigated indirectly the attritious wear of grain edge, the loading of grinding wheel and the breakage of grain through the grinding power and the surface roughness under various grinding conditions. From obtained the results, the relationship between the wheel life and the average sectional chip area is examined to guide for the determination of dressing time.

Purpose. Professional nursing ethics is a living, dynamic set of standards for nurses' professional moral behavior. Furthermore, in daily clinical nursing training, nursing students are constantly confronted with decision-making that is moral in nature. The aim of this study was to identify the perceived ethical attitudes in the clinical training process of senior nursing students using Q-methodology to offer basic strategies for nursing ethics education and thereby improve patients' care. Methods. Q-methodology provides a scientific method for identifying perception structures that exist within certain individuals or groups. Thirty-seven participants in a university rated 38 selected Q-statements on a scale of 1-9. The collected data were analyzed using pc-QUNAL software. Results. Principal component analysis identified 3 types of ethical attitudes in nursing students in Korea. The categories were labeled Sacred-life, Science-realistic and Humane-life. Sacred-life individuals think that a life belongs to an absolute power (God), not a man, and a human life is a high and noble thing. Science-realistic individuals disagreed that allowing an induced abortion or embryo (human) duplication is unethical behavior that provokes a trend, which takes the value of a life lightly; most of them took a utilitarian position with respect to ethical decisions. Humane-life individuals exhibit a tendency toward human-centered thought with respect to ethical attitudes. Conclusion. This study will be of interest to educators of students of nursing and hospital nursing administrators. Also, the findings may provide the basis for the development of more appropriate strategies to improve nursing ethics education programs.

While many criminal studies have focused on the motivation of offenders and avoidance of victimization in the micro perspective, there have been a number of theoretical developments emphasizing space as a direct factor that influences the incidence of crime. The main purpose of this study is to analyze the effects of regional characteristics and violent crime incidence in Korea. Applying diverse spatial econometrics models that have less been utilized in the crime literature, this study finds an important association between spatial accessibility and crime incidence. The results suggest that the type of predominant business and the level of road accessibility affect the vulnerability of areas with respect to the incidence of violent crime. This study concludes with some important implications for urban planners and policymakers with respect to crime control and prevention.
