본 연구는 2011년 산불피해지인 울진과 영덕지역 산불피해지를 대상으로 산불 피해강도의 공간 자기상관성 검증에 목표를 두고 수행되었다. 자기상관성은 산불 피해지의 현장조사, 피해지 모니터링 등 샘플링의 적정 이격거리 설정과 자료의 독립성 검증 측면에서 매우 중요하다. 산불 피해강도 측정을 위해 SPOT영상을 이용하여 NDVI 값을 계산하였으며, 5000개의 지점들을 GIS상에서 랜덤으로 대상지에 분산 배치시키고 지점별 NDVI 값을 샘플링하였다. 공간 자기상관도는 Moran's I값과 Variogram 모형을 이용하여 분석하였다. 분석결과 Moran's I 값이 울진의 경우 0.7745, 영덕의 경우 0.7968로 나타나 강한 공간 자기상관이 존재하는 것으로 분석되었다. Variogram 및 Lag class 별 Moran's I값 변화에 기초하여 도출된 적정한 샘플링 이격거리는 울진의 경우 566-2,151 m, 영덕의 경우 272-402 m 범위에서 상관도의 정도에 따라 다른 이격거리를 적용하여야 할 것으로 분석되었다. 이격거리를 획일적으로 적용하는 것 보다 Anisotropic 분석결과를 기초로 하여 상관도가 높은 지역에서는 크게, 반면 낮은 지역은 상대적으로 작게 유동적으로 적용하여야 효과적일 것으로 판단된다.

The purpose of the research is to analyze damages of TYLCV (Tomato Yellow Leaf Curl Virus) in the context of climate changes and to find the spatial distribution of the damages and characteristics of regions. A TYLCV is generally known for a plant disease related to temperature. Its occurrence rate increases when temperature rises. This disease first occurred in 2008 and rapidly spread nationwide. Due to the spread of a TYLCV, a number of Tomato farms in Korea were damaged severely. To analyze damages of the pest in the context of climate changes, this research estimated production loss under the current situation and RCP scenarios. Additionally, Hot Spot Analysis, LISA, and Cluster analysis were conducted to find spatial distribution and properties of largely damaged regions under RCP scenarios. The results explained that additional production loss was estimated differently by regions with the same temperature rising scenario. Also, largely damaged regions are spatially clustered and factors causing large damages were different across regional cluster groups. It means that certain regions can be damaged more than others by diseases and pests. Furthermore, pest management policy should reflect the properties of each region such as climate conditions, cultivate environment and production technologies. The findings from this research can be utilized for developing rural management plans and pest protection policies.

Purpose: To assess real-world treatment patterns, health care utilization, costs, and survival among Medicare enrollees with locally advanced/unresectable or metastatic gastric cancer receiving standard first-line chemotherapy. Materials and Methods: This was a retrospective analysis of the Surveillance, Epidemiology, and End Results-Medicare linked database (2000~2009). The inclusion criteria were as follows: (1) first diagnosed with locally advanced/unresectable or metastatic gastric cancer between July 1, 2000 and December 31, 2007 (first diagnosis defined the index date); (2) ${\geq}65$ years of age at index; (3) continuously enrolled in Medicare Part A and B from 6 months before index through the end of follow-up, defined by death or the database end date (December 31, 2009), whichever occurred first; and (4) received first-line treatment with fluoropyrimidine and/or a platinum chemotherapy agent. Results: In total, 2,583 patients met the inclusion criteria. The mean age at index was $74.8{\pm}6.0years$. Over 90% of patients died during follow-up, with a median survival of 361 days for the overall post-index period and 167 days for the period after the completion of first-line chemotherapy. The mean total gastric cancer-related cost per patient over the entire post-index follow-up period was United States dollar (USD) $70,808{\pm}56,620$. Following the completion of first-line chemotherapy, patients receiving further cancer-directed treatment had USD 25,216 additional disease-related costs versus patients receiving supportive care only (P<0.001). Conclusions: The economic burden of advanced gastric cancer is substantial. Extrapolating based on published incidence estimates and staging distributions, the estimated total disease-related lifetime cost to Medicare for the roughly 22,200 patients expected to be diagnosed with this disease in 2014 approaches USD 300 millions.

Objective: To evaluate the active-treatment effects of the Forsus fatigue resistant device (Forsus) during comprehensive correction of Class II malocclusion in growing patients. Methods: Fifty-four patients (mean age, $12.5{\pm}1.2$ years) with Class II division 1 malocclusion were consecutively treated with fixed app-liances in combination with Forsus. Lateral cephalograms were analyzed at the beginning of the fixed treatment (T1), Forsus insertion (T2), its removal (T3), and end of the comprehensive therapy (T4). Statistical comparisons were carried out by repeated-measures ANOVA with Tukey's post-hoc test (p < 0.05). Results: The overall therapeutic effects were mainly dentoalveolar and occurred mostly during the active treatment with Forsus (T2-T3, mean duration = $0.5{\pm}0.1$ years). The overjet and overbite decreased significantly (-3.5 and -1.5 mm, respectively) and the molar relationship improved by 4.3 mm. These changes were associated with significant retroclination of the maxillary incisors ($-3.1^{\circ}$), proclination and intrusion of the mandibular incisors ($+5.0^{\circ}$ and -1.5 mm, respectively), and mesialization of the mandibular molars (+2.0 mm). Conclusions: Forsus had mainly dentoalveolar effects and contributed largely to the overall therapeutic outcome.

Purpose: The aim of this study is to analyze the characteristics of family interventions based on a philosophy of family-centered care conducted in neonatal intensive care units through an integrative literature review. Methods: We searched the PubMed, CINAHL, RISS, KISS, and DBpia databases; a total of 20 studies, published between January 2013 and May 2018, was selected according to our criteria. Results: Mothers accounted for a greater proportion of participants in family interventions than did fathers. Family interventions described in the studies were categorized into four educational and sixteen non-educational interventions. Among non-educational interventions, skin-to-skin-contact interventions, such as kangaroo care, accounted for the highest proportion. Only one paper employed a theoretical framework. Conclusion: More family interventions based on theoretical frameworks should be conducted as these frameworks serve as guidelines for nursing research. As the stress patterns experienced by parents in neonatal intensive care units showed gender differences, more programs tailored for fathers are needed. Moreover, further research should be conducted to evaluate feasibility as an outcome variable, and studies of family interventions based on a philosophy of family-centered care should be performed more actively in the neonatal intensive care units in Korea.

Objective: Ozone is considered a strong antimicrobial agent with numerous potential applications in the food industry. However, its high oxidizing potential can induce alterations in foods by acting on the unsaturated fatty acids. The aim of this study was to investigate the effect of ozonation on the oxidative stability of chicken breast meat obtained from animals subjected to different feeding strategies. Methods: Samples were obtained from commercial hybrid chickens (ROSS 508), some of which were nourished with a feed enriched with fats of animal origin, while the lipid source was vegetal for the remaining birds. Samples of meat belonging to both groups were treated with ozone and then analysis was performed to evaluate alterations in physical properties, lipid content, fatty acid profile, and oxidation stability. Results: Ozone induced a significant reduction in drip loss in meat samples obtained from animals nourished with vegetable fats; this nutritional strategy also produced meats leaner and richer in polyunsaturated fatty acids. Thiobarbituric acid reactive substances, useful for the assessment of lipid oxidation, were higher in samples obtained from animals fed with vegetable fats with respect to diet based on the addition of animal fats. Conclusion: The ozone treatment improved the physical parameters of meat samples obtained from animals fed with vegetable fats, however the same samples showed a higher lipid oxidation compared to what observed in the case of the dietary intake of animal fats, probably as a consequence of the marked increase in polyunsaturated fatty acids which are more susceptible to peroxidation.

Background Applicants to integrated plastic and reconstructive surgery (PRS) residency in the United States spend exorbitant amounts of time and money throughout the interview process. Outside of first-hand experience through a visiting rotation, applicants utilize various resources in learning about a program. Today's applicants are "Millennials," the demographic cohort raised during the information age and proficient with digital technology. The authors evaluated whether programs have a presence on social media, and whether applicants are following these accounts. Methods An online survey was sent to applicants to a single integrated plastic surgery program evaluating basic demographics, social media utilization, and sources of information accessed throughout the residency application process. A manual search of popular social media platforms (Instagram, Facebook, and Twitter) was performed in October 2019. Accounts affiliated with integrated PRS programs were identified and analyzed. Results Eighty-four of 222 applicants (37.8%) completed the survey. Ninety-six percent of applicants were within the Millennial demographic. Ninety-six percent of applicants had some form of social media presence, with Facebook (90%) and Instagram (87%) being the most popular platforms. Seventy-three percent of applicants reported following a PRS residency social media account. As of October 2019, 59 integrated residency programs (73%) have active Instagram accounts. Conclusions Applicants still rely on the program website when researching potential residencies, but social media is being rapidly adopted by programs. Program social media accounts should be used as a dynamic form of communication to better inform applicants of program strengths and weaknesses.

This paper focuses on how Younghill Kang internalizes whiteness ideology through interracial romance to build himself as an oriental Yankee and recover his masculinity in his autobiographical novel East Goes West. This paper also focuses on Kang's strategy of racial and cultural hybridity presented in this novel. The theoretical basis of my argument is a mixture of Fanon's psychoanalysis in his Black Skin, White Masks, Bhabha's notion of mimicry in The Location of Culture, and notions related to race and gender of some Asian critics such as Patricia Chu, Jinqi Ling, and Lisa Lowe. In East Goes West, white women appear as "ladder of success" of successful assimilation and serve as cultural mediators and instructors and sometimes adversaries who Korean male immigrants have to win to establish identities in which Americanness, ethnicity, and masculinity are integrated. However, three Korean men, Chungpa Han, To Wan Kim, George Jum, who fall in love with white women fail to win their beloveds in marriage. George Jum fails to sustain a white dancer, Jun' interest. Kim wins the affection of Helen Hancock, a New England lady, but Kim commits suicide when he knows Helen killed herself because her family doesn't approve their relationship. Han's love for Trip remains vague, but Kang implies Han will continue his quest for "the spiritual home" as the name of "Trip." In East Goes West, Kang also attempts to challenge the imagining of a pure, monolithic, and naturalized white dominant U.S. Culture by exploring the cultural and racial hybridity shown by June and the various scenes of Halem in the 1920s. June who works for a Harlem cabaret is a white woman but she wears dark makeup. Kang questions the white face of America's self-understanding and racial constitution of a unified white American culture through June's racial masquerade. Kang shows that like Asian and black Americans, the white American also has an ambivalent racial identity through June's black mimicry and there is no natural and unchanging essence behind one's gender and race identity constitution.

Background: Correctional officers (COs) experience elevated rates of mental and physical ill-health as compared with other general industry and public safety occupations. The purpose of this study was to investigate demographic, mental health, job tenure, and work-family characteristics and their prospective association to burnout within and between jail officers during one year of new employment. Methods: In 2016, newly hired jail officers (N = 144) completed self-reported surveys across four time points in a one-year prospective study at a Midwestern United States urban jail. Linear mixed-effects and growth modeling examined how work-family conflict (W-FC) and depressive symptoms relate to perceptions of burnout over time. Results: Jail officer burnout increased and was related to rises in W-FC and depression symptoms. Within-person variance for W-FC (B_pooled = .52, p < .001) and depression symptoms (B_pooled = .06, p < .01) were significant predictors of burnout. Less time on the job remained a significant predictor of burnout across all analyses (B_pooled = .03, p < .001). Conclusions: Results from this study indicate that burnout increased during the first year of new employment; and increased W-FC, higher depression, and brief tenure were associated with burnout among jail COs. Future study of correctional workplace health is needed to identify tailored, multilevel interventions that address burnout and W-FC prevention and early intervention among COs.
