Objective : The aim of this study was to identify the validity of recruiting medical checkup participants of Vietnam veterans using a mail survey, and to identify the 'Vietnam service related characteristics' and 'general characteristics' of Vietnam veterans groups, Method : In this study, a total 900 veterans were randomly selected from the list of Vietnam veterans from f964 to 1973. The veterans were classified into 5 groups, taking into consideration their registered status in the Ministry of Patriots and Veterans Affairs: the VRD (veterans who have agent orange-related diseases), VSD (veterans who have agent orange-suspected disease), VM (veterans who peformed meritorious deeds during the war), VR (veterans who were registered with the Ministry of Patriots and Veterans Affair) and OV (other veterans) groups. By means of postal surveys, the veterans' intention to participate in the medical checkup for our research, and their socioeconomic and general characteristics were investigated. 52 surveys were returned due to the subjects not residing at the listed address, and were excluded from the analysis. Result : 699 of the 848 veterans (82.4%) responded to the survey, of which 619 (88.6%) intended to participate in the medical checkup for our research. The S veterans groups all had similar ages, Vietnam service period, Agent Orange exposure, troop characteristic and wartime class, with the exception of VM, who were older, and with a greater number of officers than the other 4 groups, There was a big difference in the health statius among the Vietnam veterans group. The VM and OV were much healthier than VRD, VSD and VR groups, The socioeconomic stati of the VRD, VSD and VR groups were lower than those of the VM and OV groups. Conclusion : Although there were some limitations, the recruitment, by mail, of medical checkup participants from Vietnam veterans is a valid and feasible method. The VM and OV groups were much healthier, and with higher socioeconomic stati, than the VRD, VSD, and VR groups.

본 연구에서는 천연 항균제인 광귤 추출물의 항균 활성과 항균 메커니즘을 조사해 즉석섭취식품인 샐러드에서 Salmonella Typhimurium을 제어하기 위한 세척수로써 적용 가능성을 평가하였다. 액체배지희석법으로 S. Typhimurium에 대한 광귤 추출물의 최소 억제 농도(MIC)를 구했다. 그런 다음 다양한 농도(1/16 MIC-2 MIC)에 해당하는 광귤 추출물에 S. Typhimurium을 접종하고 성장곡선을 분석해 대조군과 성장값을 비교하여 항균 활성을 확인하였다. 광귤 추출물을 처리한 후, S. Typhimurium의 세포 내 활성산소종 수준과 막 전위 및 손상도의 변화, 핵산 누출량을 측정하여 광귤 추출물의 항균 메커니즘을 확인하였다. 최종적으로 S. Typhimurium을 인위적으로 접종한 샐러드에 다양한 농도의 광귤 추출물을 다양한 시간 동안 침지 방법으로 항균 처리하여 저감화 효과를 확인했다. S. Typhimurium에 대한 광귤 추출물의 MIC는 195.313 mg/L으로, 1 MIC와 2 MIC의 광귤 추출물은 S. Typhimurium의 성장을 완전히 억제하였다. 광귤 추출물의 처리농도가 높아질수록, 세포 내 ROS 수준과 막 전위, 막 손상도 그리고 핵산 방출량은 증가하였다. 마지막으로, 세척수인 광귤 추출물의 농도가 높고 처리 시간이 길수록 샐러드의 S. Typhimurium의 수가 감소하였다. 따라서 광귤 추출물은 S. Typhimurium를 효과적으로 제어할 수 있음을 입증했다. 광귤 추출물은 차아염소산나트륨과 비교하였을 때 효과적인 항균 활성을 보이며 안전한 샐러드 세척수로 사용될 수 있다. 이는 샐러드와 같은 식품에서 광귤 추출물이 식중독 발생을 미연에 방지하는데 기여할 수 있음을 시사한다.

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.

본 연구에서는 베트남전 참전 군인 중 고엽제 후유(의)증 환자와 한국전쟁 참전 상이군인을 대상으로 전반적인 심리적 특성을 파악하기 위해 로샤 검사를 실시하고 반응결과를 한국전 참전 재향 군인 집단과 비교분석하였다. 이를 위해 베트남 참전 군인 중 고엽제 후유의증 환자 20명과 한국전쟁 참전 재향군인 21명을 대상으로 개별적으로 로샤 검사를 실시했다. 각각의 변인들을 Exner 종합체계(2006)의 구조적 요약의 대표적 군집들을 중심으로 비교분석하였다. 즉 핵심영역, 반응결정인, 결정적 특수지표에서의 차이를 비교분석하였다. 그 결과 베트남 참전 집단은 6.25 참전집단에 비해 (1)인지적 경직성 (2) 문제해결에 있어서의 비효율성, (3)정서억압 (4)과잉경계 (5)불안 (6)우울 등의 가능성이 더 높은 것으로 나타내었다. 이러한 결과들은 베트남전쟁 참전 재향군인에서 과거 전쟁 경험에서의 정신적 외상과 관련된 후유증이 지속되고 있을 가능성을 보여주는 것이다. 마지막으로 본 연구의 제한점과 시사점에 대해 논의하였다.

A technique for detection of Xanthomonas axonopodis pv. citri, a causal bacterium of canker on Unshiu orange fruits, was developed using bacteriophage. Procedure for the detection was designed on the basis of the previous reports that one group(CPI) of X. axonopodis pv. citri bacteriophage and corresponding two Iysotypes distributed in Korea. First, fruit surface was washed with sterile distilled water and pellet was obtained from centrifugation. The pellet was resuspended in Wakimoto's potato semi-synthetic broth medium and divided equally into two parts. One part was heated in boiling water to kill bacterial cells. Bacteriophages(CP$_1$) were respectively added into two parts and 0.1 ml from each part was mixed with soft agar medium. After incubation for 18 hrs at 25$^{\circ}C$, the causal bacterium of canker was determined based on plaques formed on the medium. This procedure can be effectively used for detection of living bacterial pathogen on fruit surfaces of Unshiu orange.

During the Viet Nam war, A Luoi located in Thua Thien Hue Province was heavily sprayed herbicides by the Ranch Hand Operation of U.S.A force (549.274 gallons). After 30 years of knocking the operation off, Dioxin has still contaminated on environment and human body in A Luoi valley. The results of the study show that there is an epidemiological relationship between AO/Dioxin exposure and increasing rate of reproductive anomalies and birth defects (the rate of reproductive anomalies including congenital deformities after the war during 10-year and 25-year is higher than that before the war from 1.5 to 4 times). The study found that the highest rate of reproductive anomalies is spontaneous abortion. The average is premature death and congenital deformities, and the lowest rate is dead foetus and hydratidiform mole. The results of the primary assessment suggested that Dioxin transport from environment to human body through the food chain exposed by Dioxin such as fish, chicken, duck. A mitigation plan for residual dioxin contamination from Agent Orange Hervicides is requeste indispensable to inhabitants in Aluoi District.

Coloring agents in food materials plays important roles in the development of attractive products as well as in the functionality of food such as antioxidant or vitamin supplementation. Carrot has been used as an orange coloring agent in the decoration of food but also a major source of vitamin A complex. Though orange has been considered a typical color of carrot, the Rainbow carrot has been developed recently, which exhibit the various colors such as red, pale yellow, purple, orange or their mixtures. After categorization onto 8 groups by their colors, vitamin A complex (${\beta}$-carotene, lycopene and lutein) and soluble sugars (glucose, fructose, and sucrose) have been analyzed in carrots. The ${\beta}$-carotene was abundant in the groups of orange (Group-O) or groups with the orange color (group-OP, and group-YOP). The content of lycopene content was exclusively high in the red color carrot (group-R). The highest lutein contents were observed from the yellow-purple (group-YP) group. Meanwhile, little amounts of lycopene and ${\beta}$-carotene were observed in yellow-purple (group-YP) nor yellow (group-Y) on yellow (group-Y). Among the reducing sugars in 'rainbow carrots', the amount of sucrose was two times higher than those of fructose and glucose. However, the content of glucose, fructose and sucrose as well as the total reducing sugars did not differ between color groups suggesting little variations on their tastes.
