Purpose: To understand the meaning of the lived experience with Person under train (PUT) for train or subway operators. Methods: The study was built on hermeneutic phenomenological themes from individual interviews of present-day train or subway operators in South Korea. Eight participants were selected to participate in the study. All qualitative data were analyzed using the heuristic guides of Van Manen. Results: Four fundamental lifeworld themes and eight sub themes emerged in the findings. The first theme of spatiality had'the place pressed by the darkness' and 'the train drags me there'. The second theme, corporeality had 'a foreboding fear', and 'debris of death that gets stuck in the whole body'. The temporality theme had'distorted time in chaos', and 'memory trapped in time'. Finally the last existential theme of relationality had 'intrapersonal encounter' and 'resentment and guilt'. Conclusion: The four existential lifeworld themes provided a framework for in-depth investigation of the operator's "lived experience." This leads to clear understanding of effects of PUT experience on related individuals. The findings imply that specific active nursing intervention strategies are necessary in order to treat affected train operators, and to prevent further issues in their work and private life.

An average of two to three typhoons that occur in the Philippines or Taiwan pass through Korea each year owing to the influence of the geographical location and western winds. Because Jinhae Bay is known as Korea's representative typhoon refuge, it is filled with ships during typhoons and later becomes saturated with ships anchored to the surrounding routes. If a strong wind drags an anchored ship, a collision accident may occur because of the short distance between the ships. Therefore, a systematic anchoring safety management of Jinhae Bay is required. In this study, the minimum wind speeds of a dragging anchor based on the water depths of Jinhae Bay anchorages were investigated. When 7-9 shackles were given, the minimum wind speeds were 48-63, 46-61, and 39-54 knots at depths of 20, 35, and 50 m, respectively. As the water depth increased, the length of the cable laid on the sea bed became shorter than 5 m owing to the external force, and the minimum wind speed showed a significant difference of 4-8 knots. In addition, ships with high holding power anchors (AC-14 type) had higher minimum wind speeds than ships with conventional anchors (ASS type). Finally, it was confirmed that at a depth of 50 m, dragging easily occurred even when a high holding power anchor was applied.

Objectives: The successful implementation of the Port Safety Special Act is a very important matter. Now that one year has passed since its introduction, this study aims to review the achievements so far and identify future tasks. Methods: The provisions of the Special Act on Port Safety were analyzed and the latest literature related to port safety management was reviewed. In addition, an in-depth interview was conducted with a business owner. Results: The achievements over the past year are as follows. As business operators took greater responsibility for safety management, blind spots in safety were resolved to an extent. Specialized training for the port unloading industry was provided, and a safety management system was established for unloading docks. In addition, the Ministry of Oceans and Fisheries was able to intervene in the prevention of safety accidents at ports through the deployment of port safety inspectors. In 2022, the port industry accident frequency and death rate declined compared to the previous year. Conclusions: The "Port Safety Special Act" has become relatively well established in the port industry over the past year. However, since the Serious Disaster Punishment Act was implemented in January of the same year, there is a limit on determining what is necessarily the effect of the Special Act. Future tasks include unifying contracts centered on cargo handling companies, supporting safety management costs, increasing the number of port safety inspectors, producing reliable port disaster statistics, and cooperating between the Ministry of Oceans and Fisheries and the Ministry of Employment and Labor.

The importance of safety culture has been emphasized to achieve a high level of safety. In this light, a systematic method to more properly deal with safety culture is necessary. Here, a decision-making tool that can apply a graded approach to the analysis of safety culture is proposed, called the F-D matrix, which determines the frequency and the difficulty of safety culture attributes recently defined by the IAEA. A hierarchical model of difficulty contributors was developed as a scoring standard, and its elements were weighted via expert evaluation using the analytic hierarchy process. The frequency of the attributes was derived by analyzing reported events from nuclear power plants in the Republic of Korea. Period-by-period comparisons with the F-D matrix can show trends in the change of the maturity level of an organization's safety culture and help to evaluate the effectiveness of previously implemented measures. In the evaluating the difficulty of the attributes in the recently developed harmonized safety culture model, the difficulties of Trending, Benchmarking, Resilience, and Documentation and Procedures were found to be relatively high, while the difficulties of Conflicts are Resolved, Ownership, Collaboration, and Respect is Evident were found to be relatively low. A case study was conducted with an analysis period of 10 years to attempt to reflect the many changes in safety culture that have been made following the Fukushima accident in March 2011. As a result of comparing two periods following the Fukushima accident, the overall frequency decreased by about 40%, providing evidence for the effects of the various improvements and measures taken following the increased emphasis on safety culture. The proposed F-D matrix provides a new analytical perspective and enables an in-depth analysis of safety culture.

Acupuncture and moxibustion play an important role not only in the medical service and health care of Korea, China and japan but also in those of many western countries such as Germany, France, United States of America. An unexpected results induced by careless acupuncture and moxibustion treatments may be mild or severe, and are due to practitioner's mistake and particular body condition of a patient. This study was performed to establish a preventive measures against medical accident induced by acupuncture therapy. Total 23 acupuncture points which are included in a J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ were selected as prohibited acupuncture points. Although the records in J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ are an important data historically which show dangerous acupuncture points, there are few a full investigation on J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ up to the present. So present study was done for literature review to understand a feasibility of the records in J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ in association with dangerous acupuncture points. Based upon the locations of these acupuncture points, the dangerous region were classified three categories, head, soma and limb. And abnormal signs related to the improperly performed acupuncture treatment on each point were investigated by using historical reference books on acupuncture and moxibustion. And then names, locations, depth of insertion, operation methods and side effects of each point were investigated.

Purpose: This research was for understanding the attitudinal difference by gender towards emotional design through questionnaire survey with female and male inpatients on environmental characteristics of wards in general hospitals. Methods: The survey was conducted by questioning inpatients at two general hospitals on the importance rating on emotional design elements of patient rooms, lounges, and hallways. Eighty questionnaires were returned and used for data analyses through SPSS windows version 15.0 statistic package program. Results: 1) In general, female patients considered emotional design of wards as more important than male patients and the most outstanding difference was indicated for patient rooms among patient rooms, lounges, and hallways. For patient rooms the comfortability index was rated as the most important to both female and male inpatient groups, and for lounges and hallways the safety index was evaluated as the most important to both gender groups. 2)For lounges, while male patients rated 'prevention of infection' important among safety relating items, women considered 'accident prevention' more important. It is inferred that female patients have more safety needs and anxiety about physical injury or accidents than male ones do. Implications: It is considered that there need to be further succeeding in-depth studies, e.g. research interviews with inpatient;s family members or other caregivers as well as patients themselves.
