Artificial reefs are structures installed to protect marine life and cultivate marine resources. After installa-tion, the effects need to be reassessed. However, despite the installation of a staggering 1,435,618 artifi-cial reefs, long-term post-installation surveys have not been conducted. The vicious cycle of artificial reefs losing their original functions due to marine debris entanglement is also frequently recognized. To address this issue, we investigated marine debris around artificial reefs by integrating leisure activities and citizen science. We conducted surveys at a total of 18 locations using three methods: Underwater Debris Survey (UDS), Common Underwater Photography (CUP), and Side Scan Sonar (SSS). The marine debris on four artificial reefs surveyed using UDS ranged from 4 to 15 items per 30 m2, weighing from 0.02 to 21 kg, with a significant proportion being plastic leisure fishing gears and discarded commercial fishing gears. By combining scuba diving, Underwater Debris Survey (UDS), and citizen science, a new type of scientific data collection, it is possible to achieve long-term monitoring of artificial reefs, obtain scientific data, and pursue marine environmental protection and sustainable development of the marine leisure industry.

Purpose: This descriptive correlational study was done to analyze the relationship between social support and self-care in hypertensive patients aged 30 years or older. Methods: Data were collected from April 09 to April 16, 2020 through an online survey (Naver Form) at Internet cafes and SNS Eighty 80 adults aged 30 or older who had been diagnosed with high blood pressure at a medical institution participated in the study. Data were analyzed using t-test, one-way ANOVA, Scheffé’s test and Pearson correlation coefficients with SPSS statistics 26.0. Results: The study results showed that social support for hypertensive patients was significantly higher for men (t=-2.17, p=.033), according to religious status (t=-2.33, p=.023), and the number of people in the household (F=6.05, p=.001). In addition, there was a significant positive correlation between social support and hypertensive self-care (r=.24, p=.036). Conclusion: The results confirm that the social support of patients with hypertension is related to self care for hypertension management. As the number of elders and single-person households who cannot manage their health well increases, it is necessary to establish a long-term and continuous social support system for these clients.

This paper presents the main method to analyze the dynamic characteristics of power transmission system using the multi-body dynamics, which is based on the concept of subsystem equation, subsystem assembling, and the self-determination technique for the system degree of freedom. We can model the mechanical components of power transmission system easily with the advantage of multi-body dynamics. Based on the theory, a dynamic simulation program was developed to analyze system performances, transient phenomena, and other dynamic problems. The driving performance of automatic transmission was simulated with using the multi-body dynamics and Newtonian method, and the validity of program was proved by comparing the two kinds of result.
인공어초 단지 주변 해양쓰레기 피해 시민모니터링과 수중 레저활동 접목 방안

인공어초는 대상 해양생물을 정착시키거나 끌어모으고, 그에 대한 배양과 보호의 목적으로 해저나 해중에 시설하는 인공구조물로 해양생물의 서식환경과 특성을 활용한 대표적인 수산자원 조성 방법이다. 2019년 해양수산부에서 발표한 ‘해양레저관광 활성화 대책’ 중 하나로 인공어초를 포함한 해중 경관이 우수한 해역을 스쿠버다이빙 포인트로 지정하여 운영하고 있다. 그러나 일부 인공어초의 경우 폐어구와 같은 해양쓰레기로 인해 원래의 기능을 상실하고, 어초에 걸린 폐어구는 유령어업을 계속하게 되는 악순환이 이어진다. 현재 해양폐기물 수거 사업은 지자체 중심으로 진행되고 있고, 인공어초 관리에 관한 통합적 자료는 미흡하다. 또한 수거에만 집중되어 발생 시기 및 원인 등과 같은 과학적 자료 역시 부족하다. 해양의 시공간적 특성상 소수의 인력으로 모든 지역을 조사하는 것은 사실상 불가능하며, 이를 보완하기 위한 방법의 하나로 시민과학과의 접목을 제안한다. 최근 스쿠버다이빙과 같은 해양레저스포츠 인구의 증가와 함께 환경보호에 대한 시민의식이 높아지고 있고, 해양의 환경문제에 직접적으로 활동하기를 원하는 사람들이 많아지고 있다. 하지만 현재 국내 해양레저스포츠 인구는 1회성 단순 체험 빈도가 높고 국외 유출 수요가 많다. 이런 스쿠버다이버들에게 수중 쓰레기 밀도 조사 방법인 UDS(Underwater Debris Survey)를 소개하고 인공어초 주변 및 다양한 해양생태계에 오염도를 조사함으로써 시민과학자로서의 역할을 부여하고 지자체에서는 지속적인 해양레저스포츠 인구를 확보하고 인공어초의 관리를 유용하게 할 뿐 아니라 전문연구인력과의 연결을 통해 인공어초 효과 및 관리에 대한 비용효율적인 대안이 될 수 있을 것이라 기대한다. As one of the Marine Leisure Tourism Revitalization Measures announced by the Ministry of Oceans and Fisheries in 2019, underwater areas with excellent scenery, including artificial reefs, have been designated and operated as scuba diving points. However, the original function of reefs is occasionally lost due to marine debris such as abandoned fishing gears, and derelict gears continue a vicious cycle of ghost fishing. Currently, the marine debris collection project is being carried out mainly by local governments, and the integrated data on the management of artificial reefs are insufficient. In addition, scientific data such as the types and cause of marine debris are also lacking. Due to the spatial and temporal characteristics of the ocean, it is virtually impossible to investigate all areas with a small number of people. Recently, along with the increase in the population of marine leisure sports such as scuba diving, public awareness about environmental protection is increasing, and people tend to be directly involved in marine environmental protection activities. However, the current population of domestic marine leisure sports has a high frequency of one-time simple experiences and a high demand for diving tour abroad. The UDS (Underwater Debris Survey), a method of surveying the density of debris deposited or sunken on the sea bottom can give scuba divers a role as citizen scientists by investigating pollution levels around artificial reefs and various marine ecosystems. It is expected that it will be a cost-effective alternative to the effectiveness and management of artificial reefs through the connection of professional researchers and scuba divers as citizen scientists.

Collision warning/avoidance systems have the potential to substantially reduce the frequency and severity of accidents. The collision warning/avoidance systems, and adaptive cruise control systems are currently under development by most automotive manufacturers around the world. This paper presents a brake control for a collision avoidance(CA) system. The proposed brake control has been compared to a simple CA algorithm which use on/off binary brake control. Nonlinear control techniques have been used to minimize driver discomfort during braking in a CA system.<br/>

Purpose: This study aimed to describe clinical nurses’ lived experiences of workplace verbal violence through qualitative research using descriptive phenomenology. Methods: Six female Korean nurses who had less than 5 years of clinical experience and had experienced verbal violence in the workplace within the past year participated in the study. Data were collected through one-on-one in-depth interviews with the participants and analyzed using Colaizzi’s phenomenological method. Results: A total of 27 codes, eight themes, and four theme clusters were derived from the participants’ statements. The four theme clusters of the clinical nurses’ experiences of verbal violence in the workplace were as follows: “tip of the iceberg,” “beyond me and my control,” “fear and resignation,” and “personal burden.” The participants recognized that nurses experienced verbal violence daily, and that the causes of and responses to verbal violence were determined by external situational factors rather than nurses’ individual problems. This suggests that nurses felt that they had no choice but to personally cope with verbal violence and bear the consequences due to systematic indifference and silence about verbal violence experienced by clinical nurses. Conclusion: The findings show that verbal violence was pervasive and unmerited, yet often endured at the cost of a personal burden to nurses. A clear definition of verbal violence and education for employees are needed, and a reporting system should be established to report all forms of violence regardless of the severity of the incident.
