Identity crafts for migration and citizenship purposes require the assistance of brokerage actors that help secure documents, advise on self-presentations, and vouch for relevant credentials. While recognizing the contradictory roles these intermediaries play in both facilitating and controlling migration and the porous boundary between for-profit and non-profit actors, scholars have yet to explore what challenges these characteristics pose to the organization of a particular brokerage transaction. How do these intermediaries reconcile their roles as migration facilitators and surrogate gatekeepers? Does it matter to present the transaction as driven by financial rewards or other loftier goals? How are the boundaries between different types of intermediaries enacted and contested? I explore these questions through the case of a religious organization that helps migrants establish their religious identities for asylum claims-making on religious grounds. Combining insights from the “relational work” approach with ethnographic research in Korean evangelical congregations in the U.S., I show how the template of gift giving allows the church to focus on making the faithful as God’s intermediary, instead of screening them as the state’s private deputy, and avoid an accusation that its trade with asylum-seekers turns the Christian persona into a quasi-commodity. The boundary between the church and commercial brokers, between gift giving and market exchange, however, is constantly contested and renegotiated through the interaction between the transaction parties. In conclusion, I discuss how the relational work approach can advance our comparative inquiry into the brokerage transactions facilitating the “profane” exchange of “sacred” identities for migration and citizenship purposes.

This article examines how ethnic capital operates in ethnic affinity migration and external citizenship. Criticizing the “methodological nationalism”, inadequate theorization of the state, and “gro...

This paper presents the bidirectional flow of reactive power between the Electric Vehicle (EV) and the grid using bidirectional charger. In addition to the battery charge and the Vehicle-to-Grid functions (V2G), the reactive power can be compensated according to an established reactive power reference. The single-phase and three-phase bidirectional power factor correction (PFC) with a DC link is connected to an isolated DC/DC bidirectional converter is utilized in the topology. The virtual flux control algorithm used in assigning the amount of the injected reactive power is presented in this paper. The required mitigation for this functionality does not require any additional hardware, and it can be implemented on the existing electric vehicles with only a firmware update. Simulation results demonstrate how the reactive power is being compensated and the saturation of the reactive current is used to keep the power under predefined limits.

Despite the centrality of the notion of “capital,” scholarship on international migration has yet to fully explore the generative potential of Bourdieu’s theory. This article “thinks with” Bourdieu to theorize how states, aspiring migrants, and migration brokers interact over the valorization, conversion, and legitimization of various types of capital for migration purposes. Drawing on Bourdieu’s theorization on the state, I identify the variegated ways in which state policies and their enactment by frontline gatekeepers constitute migration-facilitating capital. I show how migration brokers help migrants acquire adequate capital—or the semblance of possession of such capital—to contest the state’s monopolistic claim over the governance of identity, qualification, and mobility. Drawing on Bourdieu’s conceptualization of field, habitus, illusio, and symbolic violence, I analyze how migrants partake in “organized striving” for migration-facilitating capital, the uneven distribution of which produces material and symbolic stratification.

Objective: This was a correlation study for predicting the power to improve the distance of golf players and developing an effective power program. Design: Cross-sectional study. Methods: The subjects of this study were 24 healthy males and females in their 20s and 30s who were golf athletes living in Seoul and Gyeonggi-do. In the Titleist Performance Institute (TPI) Level 1 test, the twelve swing characteristics include components of stability, mobility, body conditioning ability, and balance. The power test consisted of a vertical jump (VJ) in order to examine the power of the lower body, the seated chest pass (SCP) was used to examine upper body power, and the sit up and throw (SUAT) was used to examine the power of the upper body and core for the TPI Level 2 test. Results: The results of this study showed that the 90/90 was correlated with VJ, SUAT, and SCP scores (p

Objective: The purpose of this study was to investigate the immediate effect of applying self-myofascial release (SMR) to the plantar fascia using a foam roller on hamstring and lumbar spine superficial back line (SBL). Design: Randomized controlled trial. Methods: Thirty-one healthy adults agreed to the method and purpose of the study. Selection and exclusion criteria were screened, and baseline measurements for the Toe Touch test and passive straight leg raise (PSLR) test were obtained. The participants were then randomly assigned to the SMR group or the sham group. After group assignment, the SMR group rolled the surface of the foot from the heel to the metatarsal head using a foam roller for 5 minutes. The sham group received passive mobilization of the ankle joint in the supine position. Afterwards, the Toe Touch test and the passive straight leg-raise test were re-assessed. Results: In the SMR group, the Toe Touch test results showed significant improvement (p

The aim of this study was to determine the effect of selective functional movement assessment (SFMA)-based therapeutic corrective exercise on knee joint pain in a patient with patellofemoral pain syndrome (PFPS) after pregnancy. PFPS is one of the most common causes of knee pain. The present study was conducted in a 35-year-old woman with chronic PFPS following pregnancy. She was seen every other day, 3 times a week for 8 weeks. Physical therapy was performed for tight muscles and fascia in the front, rear, left, and right following mat relaxation, with use of a form roller and corrective exercises suitable for SFMA after simple manual therapy. Corrective exercises were performed with pattern assist, unload, pattern assist with load, and load, based on a 4 × 4 matrix and the patient's status and exercise capacity. For each corrective exercise, photographic materials were also provided so that the patient could carry out the corrective exercises at home. The treatment time per session was 50 minutes. Multi-Segmental Flexion showed improvement from Dysfunctional Non-painful (DN) to Functional Non-painful (FN), Multi-Segmental Extension showed improvement from DP to FN, Single Leg Stance (both right and left) showed improvement from DN to FN, and Overhead Deep Squat showed improvement from DP to FN. The Straight Leg Raising (SLR) test showed an increase on the right from 82° to 90° and from 63° to 81° on the left. The Kujala questionnaire score increased from 63 to 94. The visual analogue scale (VAS) score decreased from 8 to 3. SFMA-based therapeutic corrective exercise was effective for chronic PFPS after pregnancy in this patient

Speaking across disciplines is always easier said than done. Engseng Ho's thought-provoking article strives to do just that (and achieves the goal nicely), with its broad overview of the literature, the numerous examples that it draws on, and the ambitious conceptual innovations it proposes. As the only sociologist invited to comment on Ho's article, I see my task as bringing Ho's article into fruitful conversation with my own discipline, which is known to be indifferent (if not hostile) to area studies and which (unfortunately) remains largely missing in Ho's imagined audience. I do so by drawing on my own work and some of the theoretical developments in the broader discipline in the past two decades or so. To make intelligible where my comments are coming from, let me begin by briefly introducing what sorts of questions interest me as a sociologist.

(1) Background: The cervical rotation-flexion test is one method of measuring the range of motion of the upper cervical spine, however, this test has not been investigated in detail. The aim of this study was to investigate the reliability and concurrent validity of the upper cervical rotation-flexion test. (2) Methods: Twenty-five healthy individuals (13 women and 12 men) participated in this study. The participants underwent radiography, the upper cervical flexion-extension test, and the upper cervical rotation-flexion test in a sitting position while wearing a cervical goniometer to measure the upper cervical flexion angle. Three experienced physical therapists administered the upper cervical rotation-flexion test using the cervical device, twice for each participant. Inter-rater and intra-rater reliabilities were evaluated using the intraclass correlation coefficient (95% confidence interval). (3) Results: The inter-rater and intra-rater reliability values of the total scores were excellent. The results of the upper cervical rotation-flexion test significantly correlated with those of the radiographic evaluation of the upper cervical flexion angle (r = 0.80, p &lt, 0.001) and those of the upper cervical flexion-extension test (r = 0.77, p &lt, 0.001). Significant correlations among the three test results were observed. (4) Conclusions: The findings of this study suggest that the upper cervical rotation-flexion test is meaningful for independently measuring the upper cervical flexion angle.

An efficient synthetic method of fluorenes having an enamine moiety at C-9 methylene bridge is developed from N-sulfonyl-4-biaryl-1,2,3-triazole derivatives via Rh-catalyzed denitrogenative cyclization in a 5-exo mode. Rh-catalyzed denitrogenative cyclization followed by catalytic hydrogenation produces N-tosylaminomethyl-substituted fluorenes in one pot. Moreover, fluorenes are synthesized via tandem Cu-catalyzed [3 + 2] cycloaddition and Rh-catalyzed denitrogenative cyclization in a 5-exo mode starting from 2-ethynylbiaryls and N-sulfonyl azides in one pot.

We report aza-[4+3] annulation through sequential [3+2]-[2+1] cycloadditions-aza-Cope rearrangement for the synthesis of dihydroazepines. Aza-[3+2] annulation was achieved through [3+2]-[2+1]-aza-Cope rearrangement-1,3-migration or [3+2]-[2+1]-Clock rearrangement, leading to the formation of dihydropyrroles. In addition, dihydroazepines thermally 1,3-migrated to give dihydropyrroles. This method affords a straightforward synthetic pathway from simple triazoles to produce dihydroazepines and dihydropyrroles together with N2 as the single byproduct. This procedure can be successfully applied to a one-pot process starting from terminal alkynes, azides, and dienes.

Studies of European colonialism have long documented how colonial states served as incubators of nationhood, yet the literature has limited its analytic scope largely to the encounters and ethnic mixings that took place within the territorial boundaries of colonies. This article examines a hitherto understudied phenomenon, the colonial state's trans-border engagement with its subjects who left the territorial unit of the colony and its impact on the contested development of diasporic nationhood. My empirical focus is the shifting trajectories of the classification struggles over Korean migrants in Manchuria during Japan's occupation of Korea. I identify the tumultuous and uneven development of specific legal, organizational, and bureaucratic infrastructures that helped the colonial state extend its trans-border reach and define and identify these migrants as “its own,” often against suspicion, sabotage, hostility, and resistance on the part of other states, indigenous populations, or migrants themselves. I argue that the colonial state's extensive and intensive transborder engagement provided a critical institutional scaffolding for the imagined community of the Korean nation, which came to be conceived as transcending the geographical boundary of the colony. This article contributes to the comparative studies of empire, migration, diaspora, and nationhood formation by challenging the prevalent sedentary bias of the existing literature, by elucidating the critical infrastructural underpinning of the formation of diasporic nationhood, and by extending the horizon of comparison to the political dynamics and long-term ramifications engendered by the migration of, not only metropolitan settlers, but also colonial subjects, within and beyond the ambit of the empire.

This study tries to investigate the functional movement of orthopedic patients with lumbar and shoulder disorders. The study subjects were 192 patients in orthopedics who were divided into the group of patients with lumbar disorders (stenosis and herniation of lumbar disk) and the group of patients with shoulder disorders (impingement syndrome and adhesive capsulitis). The functional movement test was conducted to find the difference between the two groups. In the case of lumbar disorders, out of 10 movements, cervical spinal flexion, shoulder medial rotation, shoulder lateral rotation, multi-segmental rotation, single leg stance, and over-head-deep-squat were significantly different, and the two groups had different total points. In the case of shoulder disorders, there was the significant difference only in multi-segmental flexion. Given the study results, it is effective to take into account the above movements in the course of intervening in or assessing stenosis and herniation of lumbar disk. In the future study, it will be necessary to develop an intervention program for functional movement of other disorders.

This paper examines changing German and Korean policies towards transborder coethnics (Germans in Eastern Europe and the former Soviet Union, and Koreans in Japan and China) during the high Cold War and post-Cold War eras. The paper contributes to the emerging literature on transborder forms of membership and belonging by highlighting and explaining the selective, variable, contingent, contested, and revocable nature of states’ embrace of transborder coethnics. The explanation highlights the relationship of transborder populations to predecessor polities; changing geopolitical contexts and domestic political conjunctures; the constitutive, group-making – and group-unmaking – power of state categorization practices; and the enduring institutional legacies and unintended consequences of such practices.

This article explores the politics of identification in immigration proceedings by examining the struggles over family-based immigration in South Korea in the context of ethnic Korean “return” migration from China. It focuses on micropolitical struggles in bureaucratic settings, analyzing how migrants and immigration bureaucrats struggle to establish kinship and marital status in order to secure or limit migrants' access to the labor market and citizenship. Drawing on fieldwork in both the sending and receiving communities, it shows how migrants and bureaucrats use various types of “identity tags” (official documents, performance, and biometric information) to establish the authenticity of family relations and to accept or reject particular understandings of personhood, belonging, and entitlement. It also highlights the multiple normative orderings that inform migrants' strategies (including their use of “fraudulent” identity) and their implicit or explicit challenge to the criminalizing and stigmatizing view of the immigration state.

The burgeoning literature on transborder membership, largely focused on the thickening relationship between emigration states in the South and the postwar labor migrant populations and their descendants in North America or Western Europe, has not paid due attention to the long-term macroregional transformations that shape transborder national membership politics or to the bureaucratic practices of the state that undergird transborder claims-making. By comparing contentious transborder national membership politics in South Korea during the Cold War and Post-Cold War eras, this article seeks to overcome these limitations. In both periods, the membership status of colonial-era ethnic Korean migrants in Japan and northeast China and their descendants was the focus of contestation. The distinctiveness of the case—involving both a sustained period of colonial rule and a period of belated and divided nation-state building interwoven with the Cold War—highlights the crucial importance of three factors: (1) the dynamically evolving macro-regional context, which has shaped transborder national membership politics in the region in distinctive ways; (2) the essentially political, performative, and constitutive nature of transborder nation-building; and (3) the role of state registration and documentation practices in shaping the contours of transborder national membership politics in the long run. By incorporating Korea—and East Asia more broadly—into the comparative study of transborder nation-building, this article also lays the groundwork for future cross-regional comparative historical studies.

N-Imidoylation of sulfoximines is developed from a Cu-catalyzed three-component reaction from 1-alkynes, N-sulfonyl azides, and sulfoximines in THF at room temperature under air. In addition, N-oxoimidoylation of sulfoximines is accessed from a Cu-catalyzed three-component reaction from 1-alkynes, N-sulfonyl azides, and sulfoximines in THF at room temperature followed by a Cu-catalyzed oxidative reaction at 50 °C under air, producing N-oxoimidoyl sulfoximines.
