Purpose: Agent Orange (AO) is a herbicide and defoliant used by the United States and its military allies during the Vietnam War. Pneumonia is a common cause of death among Vietnam veterans in our hospital. There have been no previous studies researching any association between AO exposure and the prognosis for pneumonia. The primary objective of this study was to investigate associations between AO exposure and 30-day mortality due to pneumonia. The secondary objective was to examine the clinical factors associated with therapeutic outcomes in veterans with pneumonia, and to assess the prevalence of combined diseases in AO-exposed veterans. Methods: This study retrospectively included veteran patients diagnosed with pneumonia in the emergency department and hospitalized between February 2014 and March 2018. The enrolled patients were grouped according to their defoliant exposure history, and the clinical information of defoliant-exposed and non-defoliant-exposed groups were compared. Patients were divided according to 30-day mortality, and significant factors influencing mortality were evaluated by using univariate analysis and multivariate analysis. The final multivariate model revealed the effect of AO exposure on therapeutic outcomes of pneumonia. Results: A total of 1006 patients were analyzed. Of these, 276 patients had a history of AO exposure, whereas 730 patients had not been exposed. Factors positively associated with 30-day mortality were malignancy, respiratory rate, blood urea nitrogen, and albumin which was negatively associated with mortality. Conclusion: Exposure to defoliant is not associated with 30-day mortality in patients with pneumonia. However, veterans with defoliant exposure are associated with a high prevalence of diabetes mellitus, hypertension, cerebrovascular accident, malignancy, and chronic kidney disease.

It is almost impossible to keep the exact documentations of veterans' works due to the fastidious and convoluted nature of this particular field. The histrorical recordings of Korean Theater in general has been improved due to growing educations of staffs and actors through theatre associated universities But the need of preserving the recordings of veteran actors has not been recognized enough, therefore their precious assets has been lost, which is such a regretful truth. However, with the necessity in mind, the following study is focused on Gil-ho Kim, an actor, playwright, director, and his works on 'Namdo-Mokpo-Plays'. Comparisons will be made, focusing on these plays, between his life as an actor and the meaning of documenting a veteran actor's assets.

The purpose of this study was to investigate teaching anxiety and the professional development of beginning secondary science teachers. For this study, a survey was conducted among beginning science teachers (N=83) with under five years of experience, and in-depth interviews with these five teachers were carried out. The survey tackled beginning secondary science teachers' anxiety levels by asking about their difficulties in teaching science classes, and results showed that the teachers' levels of teaching anxiety marked high. Levels of teaching anxiety in physics among subjects and in chemistry among experiments marked highest. To overcome teaching anxiety, teachers searched for information on the Internet or received help from their colleagues and veteran teachers. They revealed that plans for professional development as science teachers included receiving in-service training and joining teacher communities. In addition, the best type of required training program for professional development appeared to be lectures about teaching know-how from veteran teachers.

To design protection coordination for an electric power distribution system, an expert system is developed, using both the veteran expert's heuristics and the guide book for the distribution facility operation considering feeder configuration, service route, load characteristics fault current and load current. The expert system developed in this papaer determines the type of protective device(clearing current and sequence). The location and rating change of protective device in the old feeder is realized by using old database. Current(T-C) curves of various kinds of protective devices are stored in Knowledge Base (KB). The expert system is developed on a 32 bit personal computer using PROLOG, AutoCAD,dBASEIIIPLUS and FORTRAN. To compute the fault current and loadflow, FORTRAN is used.

A manufacturing environment without a computerized system causes numerous problems, since many important decisions are made based on the experience of veteran staffs. Especially, when a strategy for the improvement of manufacturing efficiency is considered, it is hard to predict the effect of the strategy. A solution to the problem without large investment of the computerized system is the simulation study. This paper shows the modeling and simulation based on DEVS(Discrete Event System Specification). Two types of models are implemented, one for representing the current production strategy and the other for the new strategy. The new strategy is expressed as priority rules within the model. The process in concern is the metal grating production process in which the size of the group, for applying a specific cutting and scheduling strategies, is one of the important factors in improving the production efficiency. Some reliable criteria for the evaluation related to the production effeciency are established from the simulation study.

The purpose of this paper is to investigate the attitudes and practices of life demanded for authentic existence in adversity, focusing on Toni Morrison's Home which was published in 2012. Home portrays the journey of Frank Money, an African-American veteran of the Korean War who strives to extricate his sister Cee from inhumane violence. Through this work, Morrison criticizes prevalent racism in the 1950s which is regarded as a time of affluence and peace through this sibling's agony. In this paper, firstly I attempt to examine the aspects of racism which Frank and Cee face and their distorted survival strategies. Secondly I try to find the right direction of brother and sister relationship based on Frank and Cee who are compared to Hansel and Gretel. Thirdly I try to point out the importance of self-reflection required for the healing process of Frank and Cee who overcome adversity and restore their identity with the help of Samaritans. And I investigate the possibility of ethical practice going beyond my family to strangers.
