Purpose: Continuous renal replacement therapy (CRRT) has been used widely for treating critically ill patients with acute renal failure (ARF). We performed this study to identify predictors of mortality in critically ill ARF patients treated with CRRT. Methods: We analyzed the data of 128 patients who were treated with continuous veno-venous he-mofiltration (CVVH) or continuous veno-venous hemodiafiltration (CVVHDF) from May, 2002 to March, 2008. We compared the clinical data of survivors with non-survivors. Results: On univariate analyses of prognostic factors of patients treated with CVVHDF, APACHE II scores (p=0.004), prothrombin time (INR) (p=0.033) and the number of inotropics used (p=0.005) were significantly lower in survivors than those of non-survivors. MAP (p=0.027), diastolic BP (p=0.015) and fibrinogen level (p=0.007) were significantly higher in survivors than those of non-survivors. Multivariate analysis revealed that APACHE II scores and fibrinogen level were the independent factors for the prediction of mortality. And on univariate analyses of prognostic factors of patients treated with CVVH, APACHE II scores (p=0.002) and the number of inotropics used (p=0.006) were significantly lower in survivors than in non-survivors. MAP (p=0.03), systolic BP (p=0.02) and diastolic BP (p=0.03) were significantly higher in survivors than in non-survivors. Multivariate analysis also revealed that APACHE II scores was the only independent factor for the prediction of mortality. Conclusion: This study showed that the independent prognostic factor for mortality in ARF patients treated with CRRT was the APACHE II score.

Mantle cell lymphoma (MCL) is an uncommon type of gastrointestinal lymphoma. MCL is a distinct subtype of B-cell non-Hodgkin lymphomas. The major subtype of MCL is characterized by the presence of multiple lymphomatous polyposis (MLP), in which multiple polyps are observed along the gastrointestinal tract. The malignant cells express pan B-cell marker and the T-cell marker cluster of differentiation 5. The chromosomal translocation t(11;14)(q13;q32) that causes cyclin D1 overexpression is commonly observed on the cytogenetic analysis of MCL. Survival improvement has recently been achieved for patient with MCL by the successful introduction of monoclonal antibodies and dose-intensified approaches for treatment, including autologous stem cell transplantation strategies. Some reports suggest that there is an increased incidence of second malignancies in patients with MCL or lymphoma. We report a case of MCL involving the colon; the patient was a 60-year-old man who complained of low abdominal discomfort during defecation. During the workup, a meningioma was unexpectedly discovered. On analysis, the tumor was found to be a t(11;14)-negative and non-MLP-type MCL. (Korean J Gastroenterol 2012;60:56-60)

CuO catalyst was prepared by surfactant-templated method using CTAB. The influence of calcination temperature on the catalytic performance of CuO catalysts for CO oxidation has been studied and their physicochemical properties were characterized by XRD, N2 sorption, and H2-TPR techniques. H2-TPR showed the existence of several forms of CuO species which were the highlydispersed CuOx species and the bulk-like CuO or larger CuO particles. The increase of calcination temperature of CuO catalyst could be directly correlated with the decrease of textural properties as surface area and pore volume and crystallite particle size. Also, CuO catalyst calcined at 300oC exhibits the highest catalytic activity, and the CO conversion achieves 100% at 175oC. Water vapor has a prohibiting effect on the efficiency of the catalyst for it competes directly with CO for the active sites on the catalyst.

한국군 병사들의 자율성과 책임성 향상 방안 연구

김의식 ( Eui-sik Kim ) 한일군사문화학회 2016 한일군사문화연구 Vol.21 No.-

한국군이 당면하고 있는 안보상황하에서 국민들로부터 잃어버린 신뢰를 되찾고, 정예화 된 선진강군으로 거듭나기 위해서는 적과 싸워 이길 수 있는 강한 전투병을 육성해야 한다. 일반적으로 강한 전투병이라고 하면 체격과 체력이 우수하고 총을 잘 쏘는 병사로 생각하기 쉽지만, 실제로 전투에서 승리할 수 있는 강한 전투병이 되려면, 우수한 체력과 숙달된 전투기술 뿐만 아니라 다양한 전장상황에 맞춰 끝까지 임무를 완수할 수 있는 자율성과 책임성도 동시에 갖추고 있어야 한다. 그러나 한국군의 현실은 그렇지 못하다. 지휘관을 비롯한 군 간부들은 겉으로는 강한 전투병 육성을 강조하고 있지만, 실제로는 병사들을 ‘관리’하는데 모든 노력을 기울이고 있다. 병사들을 체계적으로 교육훈련 시키고 스스로 임무를 완수할 수 있도록 자율성과 책임성을 키워줘야 하는데, 실제로는 사고예방에 초점을 맞추고 병사들에게는 시키는 일만 잘 하도록 강조하고 있는 것이다. 따라서 부대 내에서 반복적으로 이루어지는 일상적인 부분조차도 병사들에게는 자율과 책임을 부과하지 않고, 오로지 지휘관과 간부들의 통제에만 따르도록 하면서 모든 책임도 지휘관과 간부들에게만 부과한다. 병사들을 탁월한 체력과 전투기량, 높은 자율성과 책임성을 갖춘 강한 전투병으로 육성하기 위해서는 대체복무제를 폐지하고 전환복무요원 선발제도를 변경하는 등 현역병 획득제도를 개선해서 우수한 자원을 입대시켜야 한다. 우수한 자원이 입대하면 신병훈련소에서부터 자율활동 기회를 다양하게 부여하고, 소속대로 배치된 이후에는 팀단위 훈련, 단체활동시간, 대표병사제도 등을 통해 자율성을 향상시켜야 한다. 병사들에게 자율성을 충분히 부과한 다음에는, 자율에 따르는 책임도 부과해야 한다. 지금처럼 모든 책임을 지휘관과 간부들에게만 부과하는 잘못된 관행을 고쳐 서 행위자 중심의 처벌문화를 정착시키고, 지휘관들이 교육훈련에 매진 할 수 있도록 지휘책임 부담을 경감시켜줘야 한다.자율성과 책임성을 갖춘 강한 전투병은 단기간에 육성되는 것이 아니므로 병영 환경과 제도를 개선하고 법령을 정비하는 등 다양한 노력을 꾸준히 추진해야 한다. Given the circumstances it is presently facing, the Korean military needs to foster strong combat troops so that it can restore the public`s trust and become the respected institution that it once was. When one thinks of “strong” combat troops, one generally thinks of soldiers with physical strength and the ability to shoot accurately; however, for the institution as a whole to be strong it is necessary for the troops to be accountable and be able to carry out their tasks autonomously in addition to having adequate combat skills.But that ideal is not a reality. Although military leaders, including commanding officers, emphasize the need for strong combat forces, they use their energy mainly to manage and control soldiers. Policies are focused on accident prevention and soldiers do what they are told to do. It is the military leaders and commanding officers who bear nearly all the responsibility.A sense of autonomy and responsibility at all levels is necessary to build a strong military that can cope with the uncertainty that is inherent in battle situations.To do this, the military authorities should attract outstanding human resources into the armed forces by modifying the recruitment system and abolishing alternative service. Also, the authorities should give soldiers various opportunities to cultivate autonomy while they are at the training centre; after that, they should increase autonomy through team activities and by rewarding exemplary soldiers. Accountability, which goes hand in hand with autonomy, has to be emphasized as well. The military must rectify its current practice of holding only commanding officers accountable and must reflect accountability in its training for enlisted men and women. In conclusion, it is important to foster not only commanding officers but also combat troops who understand and accept the consequences of their actions. Because it takes a long time to train combat troops with a high level of ability, the authorities concerned should become aware of this need and reform systems accordingly.

참전명예수당 인상 및 배우자 승계문제 개선방안 연구

김의식(Eui-sik Kim) 한국보훈학회 2020 한국보훈논총 Vol.19 No.1

세계 각국은 국제평화유지 혹은 자국의 안보를 지키기 위해 전투현장에 참가했던 군인들의 희생을 기리고 그들의 명예를 고양시키기 위해 다양한 보상과 보훈제도를 운영하고 있다. 우리나라도 6․25전쟁과 월남전에 참전하여 희생되었거나 임무를 완수하고 생존한 군인들을 위해 국가차원에서 각종 보훈제도를 시행하고 있다. 그러나 우리나라의 보훈정책은 기본적으로 일제치하에서 독립운동을 하거나 6․25전쟁 기간 중 사망하거나 부상을 입으신 분들에게 중점을 두고 시행하고 있으므로, 전쟁에 참전하였으나 무사히 귀향했던 참전 군인들을 위한 국가 보훈정책은 매우 미흡한 실태이다. 군복무기간 중 전쟁이 발생하거나 국가정책에 따라 해외로 파병된다면, 본인의 의사와 무관하게 전투임무를 수행하다가 전사하거나 부상을 입을 수도 있고, 전역이후에도 참전당시 전투현장에 대한 기억으로 인해 상당기간동안 외상 후 스트레스와 같은 각종 후유증에 시달릴 수도 있다. 따라서 국가의 명령으로 참전했던 군인들에 대한 보상은 국가차원에서 충분히 이루어져야 함에도 불구하고, 전쟁터에서 무사히 귀향했던 참전 군인들에게는 국가에서 참전명예수당으로 30만원을 지급하고, 일부 지방자치단체가 자체예산으로 소액의 수당을 추가로 주고 있는 것이 현실이다. 이것은 국가를 위해 공헌했던 것에 비하면 너무나 미흡한 수준이라고 볼 수 있다. 국가보훈처에서 관리하는 여러 가지 유형의 다른 국가유공자들과 비교하더라도 턱없이 미흡한 수준의 보상을 받고 있는 것이다. 특히, 6․25참전 군인들은 전쟁으로 인해 경제활동 기회를 잃어버렸거나 축소된 가운데 지금은 대부분이 고령화되면서 힘들게 살아가는 사람들이 많다. 그리고 참전 군인들의 곁에서 참전 군인들의 외상 후 스트레스를 치유하며 살아온 배우자들은 참전 군인이 사망하면 30만원에 불과한 참전수당조차 못 받게 되므로 심각한 생계문제를 겪어야 한다. 이것은 다른 유형의 국가유공자들과 형평성의 문제가 될 수 있다. 국가가 안보위기 상황을 해소하거나, 국제평화유지 활동에 기여하기 위해서는 국민들로 하여금 자신들의 희생에 대해 국가가 충분히 보상해준다는 믿음을 가지도록 해야 한다. 그렇게 하기위해서는 국가가 위기에 처했을 때 혹은 국가의 명령으로 참전했던 군인들을 위한 참전명예수당을 다른 유형의 국가유공자들과 균형을 맞춰서 대폭 인상해야 하며, 참전 군인이 사망한 이후 남겨지는 배우자를 위해서 일정부분이 승계되도록 국가보훈제도가 개선되어야 한다. Countries around the world operate various rewards and reward systems to honor the sacrifices of soldiers who took part in combat sites to maintain international peace or protect their own security. South Korea also implements various military service systems at the national level for soldiers who were sacrificed or completed their duties during the Korean War and the Vietnam War. However, since the Korean veterans policy focuses on those who fought for independence, and died or were injured during the Korean War under Japanese colonial rule, the veterans policy for those who returned home safely after participating in the war is very insufficient. If a war breaks out during the military service of a young man or woman, or they are dispatched overseas according to national policy, he/she may be killed or injured in performing combat duties regardless of his/her will, and even after his/her discharge from the military, he/she may suffer from various aftereffects such as post-traumatic stress for a considerable period of time due to memories of the combat sites during the war. Therefore, the compensation for soldiers who enlisted and fought in the military under the orders of the nation should be made at the national level. However, the Korean government pays 300,000 won to veterans who returned home safely, and some local governments offer them a small amount of additional benefits in their own budget, which is far less than what they have contributed for the nation. Even when compared with various types of national merit, they are receiving far less compensation. In particular, most of the Korean War veterans are now very old and struggling for life, with losing or diminished their economic opportunities by the war. In addition, spouses who have lived by the veterans side to heal their post-traumatic stress will have to face serious livelihood problems as they will not be able to receive even a war allowance of 300,000 won upon the death of the veterans. This could be a matter of equity with other types of national merit. In order for the nation to resolve the security crisis or contribute to international peace-keeping efforts, the people must have the belief that the nation will fully compensate them for their sacrifice. To do so, the state should drastically increase the allowance for war veterans, who sacrificed themselves at the time of national crisis or answered for the order of the state, to balance with other types of national merit. The system of national veterans also should be improved so that some portion will be succeeded to their spouses left after the war veteran s death.
