This study examined the psychological and social factors of middle-aged conglomerate executives in Korea for successful adaptation after their involuntary retirement. For this, in-depth interviews on 13 retired executives (male, average age 58.2) including changes over time and their assessment or interpretation on them were conducted, and the contents were analyzed in phenomenological methods. As a result, 'financial preparation' and 'spousal support' were predisposing factors of adaptation. The starting point of adaptation was 'acceptance of reality', which consisted of subfactors such as reevaluating the past life, acknowledging various changes and deviating from the past, accepting themselves as common retiree in the 50s, living with anxiety, and the need of proper time. Next, they made cognitive and emotional reevaluations and reevaluated the value of life, and reestablished 'psychological reconstruction' and 'ego identity' through new activities that they chose. Their retirement and adaptation processes after retirement are the conflicting process from their experience as a conglomerate executive that satisfied psychological and social capital and the consequent story on maladaptive coping style, as well as a narration in cognitive, emotional and behavioral perspectives to overcome such disharmony. Results of this study provides implications for corporations, nation and retirees on handling retirement.

This study examined the meaning of the experiences of university students majoring in occupational therapy, where their practice was discontinued due to COVID-19, and to provide basic data for future measures. This study was a phenomenological study. The subjects of this study were seven students. Interviews were analyzed according to Colaizzi data analysis. As a result of an interview, it was organized into 17 themes, six themes clusters, and two categories. The themes clusters were indifference, problem recognition, wandering, coping, aftermath, and anticipation for coping. The students experienced a confused and frustrating situation after recognizing the problem of COVID-19 and experienced anxiety and regret as they experienced the interruption of their fieldwork. The students expected all universities to implement a batch and quick response at the same time. In the future, a systematic communication and delivery system is needed to quickly prepare and implement countermeasures at the same time as institutions, associations, and universities.

This study researched methods for coping with safety accidents by university students, after considering the situation of safety education by universities in Korea. For this study, a survey of 411 students of universities in the cities of Gwangju and Daejeon was conducted. According to the results, the ratio was high for answers such as willingness to participate in safety education beginning with the departments of engineering, art and physical training, education, art and humanity, social sciences and natural sciences, and medical sciences. It was found that university students most preferred first aid among the contents of safety education. University students of all departments answered that they had experienced safety education, but were afraid to be embarrassed in the case of actual safety accidents, as was found through the results of investigations of their awareness of coping methods with safety accidents. It was verified that many times their suffered skin and other wound in an earlier safety accident that they had experienced. This study suggests that safety education needs to be accomplished in the university curriculum, predicting and practicing for causes and factors of danger in advance, in order to improve the level of safety awareness and safety competence among university students.

During root canal preparation procedures, the potential for instrument separation is always present. Files, a lentulo, a Gates-Glidden (GG) bur or any manufactured obstruction can be left behind in the canal Nickel-titanium (NiTi) rotary files are in common usage in these days. Despite their undeniable advantages, there is a potential risk of separation within the canals. It is very rapid, unpredictable, and creates a great deal of stress for the practitioner. When an endodontic instrument separates, the best option is to remove it. Ultrasonic instruments and microscopes have improved the success rate for removing separated instruments. But It is difficult and not always possible. Therefore prevention is the key. In this case report, several management methods of separated file in the canal are presented.

The development of smart devices has affected employees' working environments and their lives. However, using smart devices is causing employees to experience technostress. This study aims to investigate the effects of technostress in using smart devices on usage intention in an organization. Moreover, the study investigates the effect of employees' stress-coping methods on the intention to use smart devices. This study posits familiarity, use innovativeness, role ambiguity, system vulnerability, technological limitation, and ubiquity as the antecedents of technostress. Data collected from 317 users who have experience in using smart devices in organizations are empirically tested against a research model using the PLS graph. Analysis results show that role ambiguity, system vulnerability, and technological limitation significantly influence technostress. Moreover, users take up emotion-focused coping behaviors because of technostress. Emotion-focused coping behaviors affect usage intention in organizations. However, technostress and problem-focused coping behaviors do not directly affect usage intention in organizations.

댐은 우리사회에 다양한 이익을 제공하는 반면 과거의 댐 붕괴 사례에 비추어 볼 때 붕괴로 인한 피해 규모는 막대하다. 세계 각국에서는 기존 댐들에 대한 잠재적 붕괴에 대비하기 위해 비상대처계획(Emergency Action Plan, EAP)과 같은 대책을 수립하여 붕괴로 인한 피해를 최소화하기 위한 노력을 기울이고 있다. 댐붕괴 모델링은 크게 댐 결괴부에 대한 예측과정과 댐 붕괴로 인한 하류부 홍수추적 과정으로 분류할 수 있다. 결괴부 예측과정은 댐붕괴로 인한 저수지 유출량에 가장 큰 영향을 미치는 부분이며 하류부 영향지역의 평가에도 매우 중요한 요소이다. 댐붕괴 예측모형은 결괴부에 대한 예측에 따라 매개변수 기반 모형과 물리기반 모형으로 분류된다. 매개변수 기반모형은 결괴형성과정을 단순 시간에 의한 함수로 고려하고 있으며 결괴부를 통한 흐름은 위어흐름으로 가정하고 있다. 이 모형은 현재 댐 붕괴 실무에서 가장 널리 이용되고 있으며 대표적인 모형은 FLDWAV/ DAMBRK 모형, HEC-RAS 모형 등이 있다. 물리기반 모형은 댐 붕괴진행 과정의 상세한 이해를 위해 시작되었으며 결괴부 흐름상황, 제체 침식, 제체가 불안정해지는 과정을 수리실험과 수리학, 토질역학, 구조역학 등의 이론을 통합하여 예측하는 기법으로 댐붕괴 과정을 좀 더 현실적으로 예측할 수 있으며 기존 붕괴된 댐들에 대한 붕괴 원인 및 진행과정을 규명할 수 있는 장점을 가진다. 최근 개발된 물리기반 댐 붕괴 모형은 HR-BREACH 모형, WINDAM 모형, FIREBIRD 모형 등이 있으며 지속적으로 연구되고 있다. 본 연구에서는 현재 진행 중에 있는 물리기반 댐 붕괴 모형들을 검토하고 현재 USDA, ARS에서 개발 중에 있는 WINDAM 모형을 이용하여 물리기반 모형의 수행에 요구되는 입력변수, 수행과정, 결과물에 대한 검토를 통해 댐 붕괴 관련 연구의 발전 방향을 모색하고 국내에서 물리기반 댐 붕괴 모형을 적용하기 위해 요구되는 사항과 한계점을 파악하여 댐 붕괴 실무로의 적용 방안을 마련하는 데 그 목적이 있다.

The maintenance of the osmolality of body fluids within a very narrow physiologic range is possible by water balance mechanisms that control the intake and excretion of water. Main factors of this process are the thirst and antidiuretic hormon arginine vasopressin (AVP), secretion regulated by osmoreceptors in the hypothalamus. Body water is the primary determinant of the osmolality of the extracellular fluid (ECF), disorders of body water homeostasis can be divided into hypo-osmolar disorders, in which there is an excess of body water relative to body solute, and hyperosmolar disorders, in which there is a deficiency of body water relative to body solute. The sodium is the predominant cation in ECF and the volume of ECF is directly proportional to the content of sodium in the body. Disorders of sodium balance, therefore, may be viewed as disorders of ECF volume. This reviews addresses the regulatory mechanisms underlying water and sodium metabolism, the two major determinants of body fluid homeostasis for a good understanding of the pathophysiology and proper management of disorders with disruption of water and sodium balance.
