Trauma Of Empire: Violence, Minor Affect, And The Cold War Transpacific

This dissertation turns to contemporary Asian American literature to examine how the aftereffects of U.S. Cold War violence and trauma manifest themselves in minor subjectivities. In the texts I explore, peripheral subjects, whose physical and psychic dislocations stem from Cold War dynamics between Asia and the United States, develop affective modes of reciprocity and intimacy and thereby collectively act out and work through historical damage. In these sites of wounded sociality, trauma appears not just as catastrophic but also as ordinary; rather than displaying itself as an individual psychic pathology, trauma is reconfigured as a collective affective labor that produces a set of minor historiographies. In rewriting the dominant U.S. Cold War historiography through a traumatic genealogy of American empire in Asia, the cultural productions this project discusses create an aesthetics of the periphery and reveal the forgotten historical sites that the progressive temporality of U.S. imperialism has occluded. The writers I explore, including Jessica Hagedorn, Jane Jeong Trenka, Aimee Phan, and Ruth Ozeki, engage multiple historical scenes of the Cold War across the Pacific, from the metropolitanization of Manila and the refugees and transnational adoptees produced by the Cold War\u27s hot wars in Korea and Vietnam to the economic alliance between Japan and the United States. This dissertation proposes that these historically, geographically broad and diverse sites are interlinked not simply through the shared experience of U.S. Cold War dominance and neoliberal governance, but also through literary mediations establishing an affective transnational zone: an alternative historical space that at once reveals the contradictions of liberal empire and produces an eccentric temporality disrupting its linear forms of progress

CULTURAL COMPETENCE LEVEL, ITS IMPORTANCE, AND EDUCATIONAL NEEDS FOR CULTURAL COMPETENCE AMONG NURSES CARING FOR FOREIGNERS IN KOREA

Purpose: This study aimed to identify cultural competency, importance, and educational requirements by analyzing nurses who were experienced in nursing foreigners in secondary hospitals and hospitals all over Korea. Methodology: A cross-sectional survey was conducted with 210 nurses from 39 hospitals in Korea. The collected data were analyzed by t-test, ANOVA, and Scheffe test. Main Findings: Satisfaction with nursing care averaged 2.48 ± 0.45. Perceived level of cultural competence averaged 2.69 ± 0.45. Cultural nursing behavior was at the highest level with 3.05±0.62; otherwise, cultural knowledge was the lowest among the subcategories (2.27±0.55). The level of importance of cultural competency was 3.69 ± 0.53. For the subcategories, cultural nursing behavior was at the highest level (3.77±0.63) and cultural awareness was at the lowest level (3.58±0.62). Training requirements had 6.83 ± 1.32, followed by cultural communication (7.34±1.50), attitudes and skills (7.04±1.50), knowledge of basics (6.83±1.33), knowledge of key concepts (6.73±1.53), and knowledge of theory and research (6.28±1.54). Implications/Applications: We suggest developing educational programs for clinical nurses to provide high-quality care to the subjects from various cultural backgrounds by strengthening cultural competency. In addition, the active support of the medical and health care institutions in improving cultural competency of nursing nurses should be emphasized

A Lightweight Block Cipher Algorithm for Secure SDN Environment

Software Defined Network is a next-generation networking technology that transforms a closed network environment based on existing network vendors into a flexible, software-based, centralized management environment that can be simplified by abstracting and programming. Although these advantages can be applied to some security problems rather than existing networks, most of the security problems and vulnerabilities of existing networks are present and various attacks are taking place. In this paper, we propose a structure to enhance the security function of SDN by checking how to implement the network security function using SDN technology and lightening the existing block cipher algorithm for this security problem. Lightweight-AES algorithm, which is a lightweight block cipher algorithm based on the AES-256 algorithm, which can simultaneously satisfy the quality of high level of security. In the case of simply reducing the number of round operations of the AES algorithm, the difference diffusion effect of the KeySchedule function generating the round key is reduced, and the security of the encryption algorithm is degraded due to the related key attack using the related key difference characteristic. The Lightweight-AES algorithm proposed in this paper improves the rate of cancellation and decryption by reducing the number of round operations, and the round internal function is supplemented to increase the differential diffusion effect of the KeySchedule function. In order to evaluate the performance of the Lightweight-AES algorithm proposed in this paper, a comparison simulation is performed with the existing AES algorithm. As a result, we confirmed that the Lightweight-AES algorithm can provide SDN content security equal to the encryption / decryption rate and algorithm security strength of the AES-128 algorithm. Therefore, it is considered that the proposed Lightweight-AES algorithm can provide better security service in SDN environment quality and security than the existing AES-128 algorithm

Infrared and Radio observations of a small group of protostellar objects in the molecular core, L1251-C

We present a multi-wavelength observational study of a low-mass star-forming region, L1251-C, with observational results at wavelengths from the near-infrared to the millimeter. Spitzer Space Telescope observations confirmed that IRAS 22343+7501 is a small group of protostellar objects. The extended emission to east-west direction with its intensity peak at the center of L1251A has been detected at 350 and 850 micron with the CSO and JCMT telescopes, tracing dense envelope materials around L1251A. The single-dish data from the KVN and TRAO telescopes show inconsistencies between the intensity peaks of several molecular line emission and that of the continuum emission, suggesting complex distributions of molecular abundances around L1251A. The SMA interferometer data, however, show intensity peaks of CO 2-1 and 13CO 2-1 located at the position of IRS 1, which is both the brightest source in IRAC image and the weakest source in the 1.3 mm dust continuum map. IRS 1 is the strongest candidate for the driving source of the newly detected compact CO 2-1 outflow. Over the whole region (14' by 14') of L125l-C, 3 Class I and 16 Class II sources have been detected, including three YSOs in L1251A. A comparison with the average projected distance among 19 YSOs in L1251-C and that among 3 YSOs in L1251A suggests L1251-C is an example of low-mass cluster formation, where protostellar objects are forming in a small group.Comment: 53 pages, 19 figures, accepted for publication in ApJ

Spectral survey of a Hot core with an Eruptive Accretion in S255IR NIRS3 (SHEA): The discovery of class I and class II millimeter methanol maser transitions

We report the detection of the millimeter CH$_3$OH masers including a new detection of class I (11$_{0,11}$-10$_{1,10}$A) and class II (6$_{1,5}$-5$_{2,4}$E) maser transitions toward the high-mass protostar S255IR NIRS3 in post-burst phase. The CH$_3$OH emissions were detected as a mixture of maser and thermal characteristics. We examine the detected transitions using an excitation diagram and LTE model spectra and compare the observed properties with those of thermal lines. Class II CH$_3$OH maser transitions showed distinctive intensity and velocity distributions from those of thermal transitions. Bright distinct emission components in addition to the fragmented and arc-shaped emissions are only detected in class I CH$_3$OH maser transitions toward southern and western directions from the protostellar position, implying the presence of the slow outflow shocks.Comment: 9 pages, 4 Figures, 1 Table, Accepted for publication in ApJ

The Risk Factors of COVID-19 Infection and Mortality among Older Adults in South Korea

Background This study aimed to identify the risk factors associated with coronavirus disease 2019 (COVID-19) infection and mortality among older adults in South Korea. Methods Using Korean National Health Insurance data from January 1, 2020, to March 31, 2022, we analyzed the impact of various factors, including age, comorbidity burden, and insurance type, on COVID-19 infection and mortality rates. Results Age was the most significant risk factor for mortality in older adults. A higher comorbidity burden was also associated with increased infection (odds ratio [OR]=1.33 for Charlson Comorbidity Index [CCI] ≥2, 95% confidence interval [CI] 1.321–1.339) and mortality (OR=1.537 for CCI ≥2, 95% CI 1.459–1.618) rates. While Medical Aid recipients exhibited lower infection rates (OR=0.898, 95% CI 0.89–0.906) than National Health Insurance beneficiaries, they had higher mortality rates (OR=1.692, 95% CI 1.623–1.763). Conclusion These results emphasized the need to prioritize vaccination and allocate healthcare resources for older adults, particularly those with multiple comorbidities. Addressing socioeconomic disparities and ensuring equitable access to testing and healthcare services are crucial for mitigating the impact of COVID-19 on older adults

Impact of very preterm birth and post-discharge growth on cardiometabolic outcomes at school age: a retrospective cohort study

Background Adverse metabolic outcomes later in life have been reported among children or young adults who were born as preterm infants. This study was conducted to examine the impact of very preterm/very low birth weight (VP/VLBW) birth and subsequent growth after hospital discharge on cardiometabolic outcomes such as insulin resistance, fasting glucose, and systolic and diastolic blood pressure (BP) among children at 6–8 years of age. Methods This retrospective cohort study included children aged 6–8 years and compared those who were born at < 32 weeks of gestation or weighing < 1,500 g at birth (n = 60) with those born at term (n = 110). Body size, fat mass, BP, glucose, insulin, leptin, adiponectin, and lipid profiles were measured. Weight-for-age z-score changes between discharge and early school-age period were also calculated, and factors associated with BP, fasting glucose, and insulin resistance were analyzed. Results Children who were born VP/VLBW had significantly lower fat masses, higher systolic BP and diastolic BP, and significantly higher values of fasting glucose, insulin, and homeostatic model assessment of insulin resistance (HOMA-IR), compared to children born at term. VP/VLBW was correlated with HOMA-IR and BPs after adjusting for various factors, including fat mass index and weight-for-age z-score changes. Weight-for-age z-score changes were associated with HOMA-IR, but not with BPs. Conclusions Although children aged 6–8 years who were born VP/VLBW showed significantly lower weight and fat mass, they had significantly higher BPs, fasting glucose, HOMA-IR, and leptin levels. The associations of VP/VLBW with cardiometabolic factors were independent of fat mass and weight gain velocity.This research was supported by a grant from the Korea Health Technology R&D Project through the Korea Health Industry Development Institute (KHID I), funded by the Ministry of Health & Welfare, Republic of Korea (HI14C3451)

Molecular Cloud Cores with a High Deuterium Fraction : Nobeyama Single-pointing Survey

We present the results of a single-pointing survey of 207 dense cores embedded in Planck Galactic Cold Clumps distributed in five different environments (lambda Orionis, Orion A, Orion B, the Galactic plane, and high latitudes) to identify dense cores on the verge of star formation for the study of the initial conditions of star formation. We observed these cores in eight molecular lines at 76-94 GHz using the Nobeyama 45 m telescope. We find that early-type molecules (e.g., CCS) have low detection rates and that late-type molecules (e.g., N(2)H(+)and c-C3H2) and deuterated molecules (e.g., N(2)D(+)and DNC) have high detection rates, suggesting that most of the cores are chemically evolved. The deuterium fraction (D/H) is found to decrease with increasing distance, indicating that it suffers from differential beam dilution between the D/H pair of lines for distant cores (>1 kpc). For lambda Orionis, Orion A, and Orion B located at similar distances, D/H is not significantly different, suggesting that there is no systematic difference in the observed chemical properties among these three regions. We identify at least eight high-D/H cores in the Orion region and two at high latitudes, which are most likely to be close to the onset of star formation. There is no clear evidence of the evolutionary change in turbulence during the starless phase, suggesting that the dissipation of turbulence is not a major mechanism for the beginning of star formation as judged from observations with a beam size of 0.04 pc.Peer reviewe
