The concept of virtual water has been largely applied in the study of regional, national, and global water flows with particular emphasis on water scarcity. Despite water traditionally being managed locally, certain global forces influence the local water resource scarcity/availability and hence virtual water exchanges worldwide. It is therefore of necessity that the significant forces be examined to understand the relationship between available water in a region and the variability and trends in environmental, social, and economic factors that are of utmost importance in the formulation of water resources management policies. This study therefore reviewed recent literature from 2003 - 2019 to determine the significant indicators of virtual water trade at different spatiotemporal levels. The study examined and compared the major approaches to virtual water trade flows accounting, and also identified and discussed policy implications and future research options concerning the analysis of virtual water trade. Available information has shown that virtual water trade is significantly influenced by economic (GDP, Demand-Supply of goods and services), geographical (Distance), institutional (population) and environmental (water availability, arable land, precipitation) factors. Reports further show that the selection of a given approach for virtual water trade flows accounting will depend on the scope of the study, the available datasets, and other research preferences. Accordingly, this study suggests that the adoption of multidisciplinary approaches to virtual water trade, taking into consideration the spatial and temporal variations in water resources availability and the complexity of environmental and socioeconomic factors will be pivotal for establishing the basis for the conservation of water resources worldwide.

Objective : Owing to advances in critical care treatment, the overall survival rate of preterm infants born at a gestational age (GA) <32 weeks has consistently improved. However, the incidence of severe intraventricular hemorrhage (IVH) has persisted, and there are few reports on in-hospital morbidity and mortality. Therefore, the aim of the present study was to investigate trends surrounding in-hospital morbidity and mortality of preterm infants with severe IVH over a 14-year period. Methods : This single-center retrospective study included 620 infants born at a GA <32 weeks, admitted between January 2007 and December 2020. After applying exclusion criteria, 596 patients were included in this study. Infants were grouped based on the most severe IVH grade documented on brain ultrasonography during their admission, with grades 3 and 4 defined as severe. We compared in-hospital mortality and clinical outcomes of preterm infants with severe IVH for two time periods : 2007-2013 (phase I) and 2014-2020 (phase II). Baseline characteristics of infants who died and survived during hospitalization were analyzed. Results : A total of 54 infants (9.0%) were diagnosed with severe IVH over a 14-year period; overall in-hospital mortality rate was 29.6%. Late in-hospital mortality rate (>7 days after birth) for infants with severe IVH significantly improved over time, decreasing from 39.1% in phase I to 14.3% in phase II (p=0.043). A history of hypotension treated with vasoactive medication within 1 week after birth (adjusted odds ratio, 7.39; p=0.025) was found to be an independent risk factor for mortality. When comparing major morbidities of surviving infants, those in phase II were significantly more likely to have undergone surgery for necrotizing enterocolitis (NEC) (29.2% vs. 0.0%; p=0.027). Additionally, rates of late-onset sepsis (45.8% vs. 14.3%; p=0.049) and central nervous system infection (25.0% vs. 0.0%; p=0.049) were significantly higher in phase II survivors than in phase I survivors. Conclusion : In-hospital mortality in preterm infants with severe IVH decreased over the last decade, whereas major neonatal morbidities increased, particularly surgical NEC and sepsis. This study suggests the importance of multidisciplinary specialized medical and surgical neonatal intensive care in preterm infants with severe IVH.

Philippines is the second world supplier of coconut by-products. As its first major genomics project, the Philippine Genome Center program for Agriculture (PGC-Agriculture) took the challenge to sequence and assemble the whole coconut genome. The project aims to provide advance genetics tools for our collaborating coconut researchers while taking the opportunity to initiate local capacity. Combination of different NGS platforms was explored and the Philippine 'Catigan Green Dwarf' (CATD) variety was selected with the breeders to be the crop's reference genome. A high quality genome assembly of CATD was generated and used to characterize important genes of coconut towards the development of resilient and outstanding varieties especially for added high-value traits. The talk will present the significant results of the project as published in various papers including the first report of whole genome sequence of a dwarf coconut variety. Updates will include the challenges hurdled and specific applications such as gene mining for host insect resistance and screening for least damaged coconuts (thus potentially insect resistant varieties). Genome-wide DNA markers as published and genes related to coconut oil qualitative/quantitative traits will also be presented, including initial molecular/biochemical studies that support nutritional and medicinal claims. A web-based genome database is currently built for ease access and wider utility of these genomics tools. Indeed, a major milestone accomplished by the coconut genomics research team, which was facilitated with the all-out government support and strong collaboration among multidisciplinary experts and partnership with advance research institutes.

As the population over the age of 65 increases, the demand for nurses who care for this group also continues to grow. Well-prepared nurses who are knowledgeable and skilled for the elderly can be prepared through systematic gerontological nursing curricula. This study was carried out to identify the needs for gerontological nursing curricular contents. The subjects for this study were two participant groups the educators who teach gerontological nursing in three-year and four-year baccalaureate nursing programs, and the nurses who are working with the elderly in hospitals, community health centers, social welfare agencies, and community health practioner's posts. The major findings of the study are as follows : 1. The differences between actual contents and essential contents of the educators : Concerning the actual contents that is actually taught, the educators showed the highest scores on the demographics of older adults and the lowest scores on the cultural variations affecting health care. Regarding the essential contents, the educators showed the highest scores on the demographics and the lowest scores on the economics of aging. Aside from the demographics, all of the items were found to have significant differences between essential and actual contents. This implies that all the content areas except demographics should be emphasized. 2. The differences between actual knowledge and essential knowledge of the nurses : Concerning the nurses' actual knowledge, the nurses showed the highest scores on the common health problems and their treatment and the lowest scores on the politics of aging. Regarding the essential knowledge, nurses showed the highest scores on the chronic illness and common health problems and the lowest scores on their roles and functions. However, they thought all the items to be essential. All of the items were found to have significant differences between actual and essential knowledge. The nurses who studied gerontological nursing in their school years and after graduating had more knowledge. However, they felt more knowledge was needed. This implies that the nurses need more education in all content areas of gerontological nursing. 3. The differences between educators and nurses : Concerning the essential contents, the educators showed higher scores on the demographics and growth and development than the nurses. Whereas, the nurses showed higher scores on the cultural variations, long-term care, economics of aging, politics of aging, legal and ethical issues, and common health problems than the educators. 4. Activities of nursing care for the elderly : Most common activities were related to direct nursing care such as giving physical care, counseling/teaching clients, and assessing and planning care for the clients. Nurses thought that all the items were critical, but they showed relatively low scores on the following :'serve on multidisciplinary committee', 'preparing reports', 'evaluation of outcomes of care', 'determine policy for nursing service', 'set patient care standards', and 'participate in nursing research' The constraints in providing better nursing service were time constraints, administrative restraints, social restraints, and inadequate knowledge.

Purpose: Cervical necrotizing fasciitis tends to involve the deep soft tissues and spread caudally to the anterior chest and mediastinum, often resulting in major complications and death. It may rapidly spread into the thorax along fascial planes, and the associated diagnostic delay results in this descending necrotizing mediastinitis. So, aggressive multidisciplinary therapy with surgical drainage is mandatory. We present a very rare case of descending necrotizing mediastinitis with literature review. Methods: A 53 years old male visited our department 7 days after trauma in neck. His premorbid conditions and risk factors of necrotizing fasciitis were concealed hepatoma, trauma history, chronic liver disease, and nutrition deficit. Computed tomographic scans of the head and neck region were performed in this patient : signs of necrotizing fasciitis, were seen in the platysma, sternocleidomastoid, trapezius muscle and strap muscles of the neck. Fluid accumulations involved multiple neck spaces and mediastinum. At the time, he diagnosed as necrotizing fasciitis on his neck and anterior chest. Necrotic wound was excised serially and we treated this with the Vacuum - assisted closure(VAC, Kinetics Concepts International, San Antonio, Texas) system device. After appropriately shaping the sponge and achieving additional 3 pieces drainage tubes in the pockets, continuous negative pressure of 125 mmHg was applied. The VAC therapy was utilized for a period of 12 days. Results: We obtained satisfactory results from wide excision, abscess drainage with the VAC system, and then split thickness skin graft. The postoperative course was uneventful. Conclusion: The refined technique using the VAC system can provide a means of simple and effective management for the descending necrotizing mediastinitis, with better cosmetic and functional results. Finally, the VAC system has been adopted as the standard treatment for deep cervical and mediastinal wound infections as a result of the excellent clinical outcome.

본 연구에서는 이제까지의 말더듬에 대한 여러 이론들을 살피고 말더듬 치료의 임상 경험을 보고하고자 하였다. 말더듬의 원인이나 치료법에 관한 수많은 연구가 있어왔으나 아직도 이에 대한 한마디의 명확한 답을 내리기는 어렵다 다만 말더듬에 대한 이해를 점차 넓혀가고 있고, 보다 효과적인 치료에 접근하고 있다고 본다. 말더듬의 원인을 기질적 요인으로 보는 주장, 심리적 요인으로 보는 주장, 학습적 요인으로 보는 주장, 환경적 요인으로 보는 주장들이 있어왔다. 이에 따라 치료법도 다양한데 크게는 말더듬 수정법과 단계적 유창성 완성법으로 나누어진다. 본 연구자는 말더듬 치료에 각 아동이 갖을 수 있는 복합적 요인을 살피고 치료에서도 한가지를 고수하기 보다는 통합적으로 접근해야 한다는 입장을 취하였다. 이에 따라 대상이된 아동들의 문제는 다각적으로 살펴졌고 각 아동은 개별 언어 치료를 받고 이어서 그룹치료를 받았다. 그룹치료의 목표는 좀더 어려운 언어 상황으로까지 유창성을 높이고 유창성의 일반화를 유지하는 것이었다. 대상이된 세 아동은 모두 ‘읽기’ 그리고 ‘대화’, 상황에서 유창성을 높였고 전체 말더듬 행동에도 호전을 보였는데 그룹치료에서는 특히 ‘대화’에서 유창성을 높일 수 있었다. 말더듬의 각 요인들을 살필 수 있는 민감한 진단 도구의 개발과 말더듬 이론이 반영된 보다 진보적인 치료 프로그램의 개발이 계속되어야 함이 토의되었다.

만성 폐쇄성 폐질환은 비가역적, 점진적 기도 폐쇄가 특징인 주요 사망 원인중의 하나이다. 말기 폐쇄성 폐질환 환자는 다양한 신체적, 정서적, 사회적, 기능적 문제로 인해 호스피스 완화의료가 필요하다. 따라서, 완화의료의 목적은 증상 조절, 운동 능력 및 삶의 질 향상이며, 아울러 급성 악화 빈도를 줄이고 질병의 진행을 늦추는 효과를 기대할 수 있다. 다양한 진행 과정 때문에 말기 시점을 예측하기 어렵다. 호흡곤란 정도, 폐기능, 혈액학적 임상 지표를 이용하여 대상자를 선정하는 기준을 마련하고 적용시점을 논의해야 한다. 질환의 특성상 진단 후 초기에는 완치 목적의 치료가 중심이 되어 완화의료가 이를 보완하는 방식으로 적용되다가, 완치 목적의 치료를 위해 입 퇴원을 반복하거나 치료의 반응이 낮고 나쁜 예후가 예상될 때 완화의료 비중이 확대되는 것이 바람직하겠다. 폐쇄성 폐질환 환자에게 적극적으로 호흡재활을 적용하고, 환자의 의사결정을 존중하여 증상 악화 이전에 미리 대책을 마련하고 앞으로의 치료 목표를 논의하기 위한 완화의료 팀을 구성하고, 국내 현실에 맞는 진료 연계 체계를 마련하는 것이 필요하다. 제도가 잘 정착하기 위해서는 일차 의료 및 암환자 대상의 완화의료 전문 팀과의 협업이 중요하며, 우선 고려되어야 할 것이다.

Background : To save out-of-hospital cardiac arrest cases is a major concern for Korea. Cardiac arrest is a very common problem, with > 18,000 cases dying each year in Korea. Overall, survival to hospital discharge remains poor. Resuscitation has become an important multidisciplinary branch of medicine, demanding a spectrum of skills and attracting a plethora of specialities and organizations. Since the "Utstein Style" was advocated in 1991, many reports about out-of-hospital cardiac arrest have been published based on this guideline. These differences prevent valid inter-hospital and international comparisons. However, we do not know the true effectiveness of resuscitation. There are no guideline for reviewing, reporting, conducting research on resuscitation in Korea. This study evaluated the out-of-hospital factor associated with survival discharge of out-of-hospital cardiac arrest, was especially to provide basic data for the unified reporting guideline of resuscitation in Korea. Methods : From January 1990 to July 2004, we collected data about out-of-hospital cardiac arrest at Wonju Christian Hospital(WCH-CAD), Ewha Women University Mokdong Hospital(Ewha-CAD), I used same record form based on the "Utstein Style". The "Utstein Style" is internationally recommended guidelines for reporting outcome data from resuscitation events. Results : Resuscitation was performed in 1443 out-of-hospital cardiac arrest patients at 2 hospitals. Five hundred eighty(40.25%) patients recovered the spontaneous circulation at least once and One hundred sixty eight(11.66%) patients discharged alive. Initial EKG showed Ventricular Tachycardia/Ventricular Fibrillation in One hundred thirty five(9.33%) patients, asystole in one thousand nine(69.73%) patients and other rhythms in one hundred thirty nine(20.94%) patients. Among one hundred two cardiogenic cardiac arrest patients, two(2.0%) patients was discharged alive. Conclusion : Overall survival rate of out-of-hospital cardiac arrest patients was 11.66% which was poorer than that of the western country. The proportion of the cardiogenic cause was 33.38% which was only half of the western country. VT/VF is relatively not common ac a initial EKG rhythm. These differences might be to due difference in the prevalence pattern of out-of-hospital cardiac arrest as well as prematurity of the EMSS. It is needed that the best survival can be achieved if all following links have been optimized : rapid access, early CPR, early defibrillation, early ACLS.
