The Japan National Committee for the Union for International Cancer Control (UICC) and UICC-Asia Regional Office (ARO) organized a Roundtable Discussion as part of the official program of the UICC World Cancer Congress 2014 in Melbourne, Australia. The theme for the Roundtable Discussion was "Looking Toward the Realization of Universal Health Care 'UHC' for Cancer in Asia" and it was held on December 5, 2014. The meeting was held based on the recognition that although each country may take a different path towards the realization of UHC, one point that is common to all is that cancer is projected to be the most difficult disease to address under the goals of UHC and that there is, therefore, an urgent and pressing need to come to a common understanding and awareness with regard to UHC concepts that are a priority component of a post-MDG development agenda. The presenters and participants addressed the issue of UHC for cancer in Asia from their various perspectives in academia and international organizations. Discussions covered the challenges to UHC in Asia, collaborative approaches by international organizations, the need for uniform and relevant data, ways to create an Asia Cancer Barometer that could be applied to all countries in Asia. The session concluded with the recognition that research on UHC in Asia should continue to be used as a tool for cancer cooperation in Asia and that the achievement of UHC would require research and input not only from the medical community, but from a broad sector of society in a multidisciplinary approach. Discussions on this issue will continue towards the Asia-Pacific Cancer Conference in Indonesia in August 2015.

Eupatilin, one of representative medical components of mugwort, can be efficiently extracted from the 'Gangwha Sajabalssuk'. The Eupatilin content may depend on environmental factors such as soil and regional climate in addition to a genetic factor and Gangwha region has a profitable environmental condition for the mugwort growth. In this study, the climatological characteristics of Gangwha was analyzed in order to find the environmental condition of mugwort containing high Eupatilin in term of atmospheric, oceanographic and land variables. The climate of Gangwha is characterized by the relatively low daily temperature and large diurnal variation with plenty of solar radiation, long sunshine duration and less cloudiness. According to our correlation analysis, the long sunshine duration and the large diurnal temperature variation are highly correlated with the Eupatilin contents. The result implies that Gangwha has the favorable conditions for the cultivation and the habitat of the high-Eupatilin concentrated mugwort. Because of the sea surrounding Gangwha Island with low salinity and moderate wind, the salt contained in sea breeze is relatively low compared to other regions. Furthermore, Gangwha has clean atmospheric environment compared to other regions because the concentrations of toxic gases harmful to crop growth such as nitrogen dioxide ($NO_2$), sulfite gas ($SO_2$) and fine dust (PM-10) are lower in the air. The ozone ($O_3$) concentration is moderate and within the level of natural production. It is also found that moderately coarse texture or fine loamy soils known as good for water drainage and for the growth and cultivation of the 'Gangwha-mugwort' are distributed throughout the areas around mountainous districts in Gangwha, coinciding with those of mugwort habitat.

Purpose: $^{123}I$-labeled fatty acids have been used in the evaluation of regional myocardial energy metabolism. This study aimed to evaluate the usefulness of $^{123}I$-BMIPP as a liposarcoma-imaging agent. Materials and Methods: We compared in vitro uptakes between liposarcoma(SW872) and glioma(9L) cell lines, and examined biodistribution and in vivo images of $^{123}I$-BMIPP in liposarcoma-bearing nude mice. Cold-BMIPP was labeled with $^{123}I\;using\;Cu^{2+}$ as catalyst. After purification by Sep-pak, radiochemical purity was determined by TLC. We compared cellular uptake between glioma and liposarcoma after incubation of 5, 10, 15, 30, 60, 120, and 180 mins with culture medium containing $^{123}I$-BMIPP. The difference in biodistribution was determined between non-feeding (water only) group for 18 hr and feeding group in normal mice (n=6/group) at 0.5, 2, and 24 hr. In liposarcoma-hearing nude mice model, liposarcoma, SW872, ceil lines were injected subcutaneously into the felt thigh of nude mice. The biodistribution of $^{123}I$-BMIPP was evaluated at 0.5, 2, and 24 hr (n:5 / group) and in vivo Image of $^{123}I$-BMIPP was obtained with gamma camera at 2 and 24 hr in liposarcoma-hearing nude mice. Results: Radiolabeling yield and radiochemical purity were 95% and above 99%, respectively. SW872 cell line showed more increased uptake than 9L with 1.5 times at 180 mins. The clearance of $^{123}I$-BMIPP in various tissues was more delayed in the non-feeding group than in the feeding group, especially at delayed time (24 hr) in normal mice, and the major excreting organ was the gastrointestinal tract. In liposarcoma-bearing nude mice, tumor/blood ratio of $^{123}I$-BMIPP was 0.94, 0.75, and 1.38 and tumor/muscle ratio was 0.66, 1.53, and 1.11 at 0.5, 2, and 24hr, respectively. $^{123}I$-BMIPP was selectively localized in liposarcoma at 24 hr image. Conclusions: These results suggest that $^{123}I$-BMIPP can be used as a liposarcoma-imaging agent.

Objectives: This study aimed to explore whether there are differences in smoking status between two regions of Wonju-City and Chuncheon-City, Gangwon State, and to determine whether the experience of smoking cessation programs in the region affects quit attempts. Methods: The study design was a cross-sectional study in which adults aged 19 and older living in two cities were surveyed using a pre-developed mobile app to investigate social capital for smoking cessation, and a total of 600 citizens were participated, including 310 in Wonju-City and 290 in Chuncheon-City. The statistical analysis was conducted using chi-square test and logistic regression analysis. Results: Wonju-City had a higher prevalence of current smoking than Chuncheon-City. Among smoking cessation programs operated by local public health centers, Wonju-City had a lower odds ratio for experience with smoking cessation education than Chuncheon-City (OR=0.52, 95% CI=0.33 to 0.81). When examining the effect of smoking cessation program experience on quit attempts, in Wonju-City, citizens who had completed smoking cessation education and used a smoking cessation clinic were more likely to attempt to quit than those who had not (OR=2.31 and OR=2.29, respectively). In Chuncheon-City, citizens who were aware of smoking cessation support services were 2.26 times more likely to attempt to quit smoking than those who were not, but statistical significance was not reached due to the small sample size. Conclusion: Therefore, healthcare organizations in both regions should develop more practical intervention strategies to increase smokers' quit attempts, reduce smoking rates in the community, and address regional disparities.

Purpose: The aim of this study was to evaluate the normal values of regional cerebral blood flow (rCBF) and cerebrovascular reserve (CVR) in normal children to aged volunteers using Tc-99m HMPAO, Materials and Methods: Thirty four right-handed normal volunteers (20 males, 14 females, mean age $40.3{\pm}24.9$ years, range 4 to 82 years) were underwent rost/acetazolamide (ACZ) brain SPECT using Tc-99m HMPAO and the sequential injection and subtraction method. rCBF was estimated on the basis of a semiquantitative approach by means of right/left ratio, region/cerebellum and region to whole brain ratios in (rental, parietal, temporal, and occipital lobes, basal ganglia, thalami, and cerebellum. CVR was measured by means of % perfusion increase calculated as % mean count change compared to rest rCBF in each regions. Results: Mean values of right to left ratios range from 1.004 to 1.018, rCBF was highest in cerebellum and lowest in basal ganglia and thalami. Frontal and temporal rCBF decreased while occipital and thalamic rCBF increased according to age. No sexual difference of rCBF was noted. Mean CVR was $29.9{\pm}12.9%$. Mean CVR significantly increased to late teens, and declined thereafter. After 6th decade, CVR in both frontal lobes, left parietal lobe and right basal ganglia decreased significantly with advancing age. There was no sexual difference of CVR. Conclusion: Quantitative assessment of CVR was possible by ACZ Tc-99m HMPAO brain SPECT. It revealed that rCBF and CVR changed according to age in normal Korean volunteers. There was no sexual difference.

Gray leaf spot (GLS) is a serious fungal disease caused by Pyricularia oryzae Cavara, recently reported on the important turf and forage species, perennial ryegrass (Lolium perenneL.). This fungus also causes rice blast, which is usually controlled by host resistance, but durability of resistance is a problem. Few instances of GLS resistance have been reported in perennial ryegrass. However, two major QTL for GLS resistance have been detected on linkage groups 3 and 6 in an Italian x perennial ryegrass mapping population. To confirm that those QTL are still detectable in the next generation and can function in a different genetic background, a resistant segregant from this population has been crossed with an unrelated susceptible perennial clone, to form a new mapping population segregating for GLS resistance. QTL analysis has been performed in the new population, using two different ryegrass field isolates and RAPD, RFLP, and SSR marker-based linkage maps for each parent. Results indicate the previously identified QTL on linkage group 3 is still significant in the new population, with LOD and percent of phenotypic variance explained ranging from 2.0 to 3.5 and 5% to 10%, respectively. Also two QTL were detected in the susceptible parent, with similar LOD and phenotypic variance explained. Although the linkage group 6 QTL was not detected, the major QTL on linkage group 3 appears to beconfirmed. These results will add to our understanding of the genetic architecture of GLS resistance in ryegrass, which will facilitate its use in perennial ryegrass breeding programs.

Cucumber green mottle mosaic virus (CGMMV) is one of major plant viruses infecting cucurbitaceous crops via soil or infected seeds. This study investigate ecology of infection of CGMMV in soil, and control tactics of this virus with soil hygiene and crop rotation. This virus was survival to 50% in soil without host plants for 17 months and had high vitality in debris of infected plant over 1 year. Infection rate of CGMMV was 1.0~3.6% in control soil and 12~36% in soil transplanted with wounded root of watermelon. It showed that wounded root may affect severity of soil infection. Rotation between rice and watermelon caused dramatical reduction from 76.8% in repeated cultivation to 7.3% of progeny infection by CGMMV. Therefore, it is suggested that crop rotation be effective for control of CGMMV.

Purpose: Hemorrhagic shock is the leading cause of death in trauma patients worldwide. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique used to improve the hemodynamic stability of patients with traumatic shock and to temporarily control arterial hemorrhage. However, further research is required to determine whether REBOA with cardiopulmonary resuscitation (CPR) in near-arrest or arrest trauma patients can help resuscitation. We analyzed trauma patients who underwent REBOA according to their CPR status and evaluated the effects of REBOA in arrest situations. Methods: This study was a retrospective single-regional trauma center study conducted at a tertiary medical institution from February 2017 to November 2019. We evaluated the mortality of severely injured patients who underwent REBOA and analyzed the factors that influenced the outcome. Patients were divided into CPR and non-CPR groups. Results: We reviewed 1,596 trauma patients with shock, of whom 23 patients underwent REBOA (1.4%). Two patients were excluded due to failure and a repeated attempt of REBOA. The Glasgow Coma Scale score was lower in the CPR group than in the non-CPR group (p=0.009). Blood pressure readings at the emergency room were lower in the CPR group than in the non-CPR group, including systolic blood pressure (p=0.012), diastolic blood pressure (p=0.002), and mean arterial pressure (p=0.008). In addition, the mortality rate was higher in the CPR group (100%) than in the non-CPR group (50%) (p=0.012). The overall mortality rate was 76.2%. Conclusions: Our study suggests that if REBOA is deemed necessary in a timely manner, it is better to perform REBOA before an arrest occurs. Therefore, appropriate protocols, including pre-hospital REBOA, should be constructed to demonstrate the effectiveness of REBOA in reducing mortality in arrest or impending arrest patients.

Background: Surgical resection is the standad therapy for the stage I lung cancer. We analysed the risk facturs of stage I lung cancer patent and tryed to establish more effective and aggressive treatment modality. Materials and methods: A detailed analysis was undertaken to evaluate the surgical results and to define the risk factors associated with the recurrence and the survival time in 146 consecutive patients with stage I lung cancer who were diagnosed, and resected at Yonsei Medical Center from January 1990 to December 1996. Results: There were 115 males and 31 females. Their ages ranged from 27 to 79 years(mean age:58.9$\pm$9.3 years). The histologic types were squamous carcinoma in 72 cases(49.3%) and adenocarcinoma in 45 cases(30.8%). A pulmonary resection and mediastinal lymph node dissection were done in all cases. A lobectomy was performed in 96 cases(65.7%) and a pneumonectomy in 48 cases(32.9%). There were 5 operative mortalities(3.4%) and complications occured in 24 cases(16.5%). The overall 5-year survival was 64.1%, and survival time did not depend on the type of operation or histologic type. Significant predictors of decreased survival were visceral pleural invasion(p=0.0079), T2 lesion(p=0.0462), and tumor size($\geq$5 cm) in adenocarcinoma(p=0.0472). The overall incidence of recurrence was 33.3%(47 cases; local or regional 6.4%, distant 26.9%). Almost all recurrences(44cases) occurred in T2 lesions. The distant organs that failed were the contralateral lung in 13 patients, the brain in 12, the bone in 10, and other organs in 3. Conclusions: even in stage I lung cancer, we suggest that postoperative adjuvant therapy is recommended in patients with poor prognostic factors such as visceral pleural invasion, T2 lesions, and a tumor size($\geq$5 cm) in the adenocarcinoma.

This study examined the prevalence of an impaired fasting glucose and related factors in normal non-diabetic adults. This study used the raw data (general characteristics, health behavior, obesity, impaired fasting glucose etc.) from the 6th Korea National Health & Nutrition Examination Survey (NHANES) in the second year (2014), and out of all 7,550 survey participants, 1,341 were selected as the final research subjects. After stratifying according to obesity, a logistic regression model was used to analyze the factors related to an impaired fasting glucose level. The older subjects were more likely to have an impaired fasting glucose in both the obesity group and normal weight group (p<.001). The obesity group showed a higher impaired fasting glucose rate when they drank more alcohol (p<.05) and consumed less fruit (p<.05). Therefore, balanced nutrients and control of the blood sugar level through proper education and public health policies of fruit intake and alcohol are needed.
