Lee,Yoonjeong(이윤정 ) 한국교육학회 2024 敎育學硏究 Vol.62 No.3

This study aims to investigate the formulation, development, and achievement of the motivation of aspiring headteachers in secondary schools in the Republic of Korea (hereafter, Korea). Because it is a sought-after position, aspiring headteachers undertake highly competitive and time-consuming processes to become headteachers. Educational leadership is important for school effectiveness and improvement. Understanding the motivation of aspiring headteachers will be useful to support educational leadership preparation. Thus, a qualitative study was conducted, and thirty-three headteachers were invited to semi-structured interviews to share their motivation from the start until they were appointed. In the findings, leadership capability was revealed as the inevitable reason for formulating motivation. When leadership capability was recognized, the participants were recommended to apply for the educational specialist role or to become the head of the education and research department, which are the typical pathways to becoming a headteacher in the Korean education system. In the development process, firstly, high social status was regarded as the extrinsic motivation (receiving), while financial rewards were not considered as extrinsic motivation. Secondly, being able to have a voice in the school and the education system emerged as a main intrinsic motivation (achieving). Lastly, most aspiring headteachers wanted to contribute to the improvement of the school and the education system; this motivation was linked to transcendent motivation (giving). Extrinsic motivation was easily shown on the surface, but intrinsic (achieving) and transcendent (giving) motivations were revealed as more meaningful motivations under the surface. Even though these motivations were genuine, educational leadership skills are considered essential to achieving transcendent motivations. This study suggests that it would be helpful for educational leadership preparation programs to be designed with an understanding of aspiring headteachers’ motivation. 본 질적 연구는 대한민국(이하 한국)의 중등학교 교장 지원자들의 동기를 연구하는 것을 목적으로 한다. 한국에서 교장의 지위는 모두가 원하는 자리 중 하나이므로, 교장이 되기 위해서 교장 지원자들은 오랜 시간에 걸친 치열한 경쟁의 과정을 통과해야만 한다. 교장 지원자들의 동기 연구는 이들이 효과적으로 리더십 역량을 개발하는 것에 꼭 필요하다. 이를 위해 질적 연구가 계획되었고, 33명의 교장 선생님들이 반구조화된 인터뷰에 참여하였는데, 이 참가자들은 교장 지원자들이 처음 동기를 형성하는 단계부터, 발전을 거쳐 성취하는 단계를 직접 경험하였기에, 본 연구에서 필요한 각 단계의 질문에 대해 유의미한 답변들을 제공할 수 있었다. 연구 결과, 동기 형성의 과정에 리더십 역량은 교장 지원자들이 교장이 되는 길로 들어서는데, 하나의 뚜렷한 원인이 되었다는 것을 알 수 있었다. 리더십 역량이 인정되었을 때, 지원자들은 교육 전문직 또는 교육연구 부장직을 맡게 됨으로써 교장 지원자의 길로 들어섰다. 교장이 되겠다는 동기는 이 과정에서 점차적으로 개발되어 나간 것으로 보인다. 외재적 요인으로 높은 사회적 지위는 동기를 강화하는 요인으로 나타났고, 반면, 금전적 보상은 교장 지원자들에게 동기로서 고려되지 않았다. 다음으로, 학교에서 교과과정을 구성하고, 교육청에서 정책을 입안하고 시행하는 업무 등을 통해 자신의 의견을 학교 교육과 교육정책에 반영하고 싶다는 내재적 동기와 학생, 학교 및 교육 시스템을 개선하고 발전시키는 것에 적극적으로 기여하기를 원하는 초월적 동기가 주요 동기로 드러났다. 표면적으로는 외재적 요인이 동기로 드러났지만, 내재적 요인과 초월적 요인이 한국의 교장준비 과정을 수행할 수 있는 더욱 중요한 동기가 됨을 알 수 있었다. 교장 지원자들이 진정성 있는 초월적인 동기를 가지고 있더라도, 이를 달성하기 위해서는 교육 리더십의 역량이 필수적이다. 이는 또한 교장들의 동기를 이해하는 것은 적절한 교육 리더십 준비과정을 설계하고 지원하는 것에 도움이 될 것이다.

Background: To examine the incidence of traumatic spinal cord injury (TSCI) from all etiologies, we measured and compared the incidence of TSCI from three national or quasinational databases in South Korea, namely, the National Health Insurance Service (NHIS), automobile insurance (AUI), and Industrial Accident Compensation Insurance (IACI). Methods: We reviewed patients with TSCI reported in the NHIS database between 2009 and 2018, and in the AUI and IACI databases between 2014 and 2018. TSCI patients were defined as those first admitted to the hospital with a diagnosis of TSCI according to the International Classification of Diseases (10th revision) criteria. Age-adjusted incidence was calculated using direct standardization using the 2005 South Korean population or the 2000 US population as the standard population. The annual percentage changes (APC) of TSCI incidence were calculated. The Cochrane–Armitage trend test was performed according to the injured body region. Results: In the NHIS database, age-adjusted TSCI incidence using the Korean standard population increased significantly from 2009 to 2018 (from 33.73 per million in 2009 to 38.14 per million in 2018, APC = 1.2%, P = 0.014). Contrarily, age-adjusted incidence in the AUI database significantly decreased from 13.88 per million in 2014 to 11.57 per million in 2018 (APC = – 5.1%, P = 0.009). In the IACI database, the age-adjusted incidence showed no significant difference, while crude incidence showed a significant increase (from 22.02 per million in 2014 to 28.92 per million in 2018, APC = 6.1%, P = 0.038). According to the age group, all the three databases showed high incidences of TSCI in those in their 60s and 70s or older. Among those in their 70s or older, the incidence of TSCI increased dramatically in the NHIS and IACI databases, while no significant trend was found in AUI database. In 2018, the number of TSCI patients was the highest among those over 70 years of age in the NHIS, whereas among those in their 50s were the highest in both AUI and IACI. The proportion of patients with cervical spinal cord injury was the most common in all these databases. Conclusions: The differences in trends in the incidence of TSCI may be due to the different etiologies and different characteristics of subjects depending on insurance type. These results imply the need for tailored medical strategies for the different injury mechanisms represented by three national insurance services in South Korea.

본 연구는 학교 밖 청소년의 자살 시도 예측 변수를 조사하기 위해 학업중단청소년 패널조사 1차년도 조사자료를 사용한 2차 데이터 분석 연구이다. 자료 분석은 SPSS 26.0 통계 프로그램을 사용하여 수행되었다. 연구에 포함된 776명의 참가자 중 62명(8%)에서 학업중단 이후 자살 시도가 보고되었다. 로지스틱 회귀분석 결과, 학업중단 이전의 자살시도 경험(OR=10.66), 폭력피해 경험(OR=6.97), 음주(OR=3.73), 우울(OR=2.62), 부모애착(OR=0.47), 또래와의 관계(OR=0.63)가 학업 중단 이후 자살 시도의 유의한 예측인자였다. 따라서 학교 밖 청소년의 자살 시도를 예방하기 위해서는 학업 중단 전의 자살 시도 경험을 확인해야 한다. 또한 심리적 상황, 대인관계, 폭력경험 등을 고려한 융합적 자살예방 프로그램의 수립이 필요하다. This study is a secondary data analysis study using the 1st Panel Survey of School Dropouts in Korea for investigating predictors of suicide attempts in out-of-school youths (OSYs). Data analysis were performed using the SPSS 26.0 statistical program. Suicide attempts were reported in 62 (8%) of the 776 participants included in the study. Logistic regression analysis revealed that suicide attempts before school dropout (OR=10.66), experience of violence victimization (OR=6.97), alcohol consumption (OR=3.73), depression (OR=2.62), parental attachment (OR=0.47), peer relationships (OR=0.63) before school dropout were significant predictors of suicide attempts. Prevention of suicide attempts by OSYs should be preceded by confirmation of their experience in suicide attempts before school dropout. In addition, it is required to establish a suicide prevention program considering psychological situations, interpersonal relationships, and violence experiences.

Acquired brain injury (ABI) is a leading cause of serious long-term disability resulting in substantial economic costs for post-ABI care. This study was conducted to estimate the socioeconomic burden of persons with ABI in Korea. We used a prevalence-based approach and societal perspective to estimate the direct medical, non-medical costs and indirect costs of ABI, including stroke, traumatic brain injury (TBI), and non-traumatic ABI (anoxia, brain tumor, encephalitis, meningitis, hydrocephalus, and other brain disorders) from 2015 to 2017. The study population included patients with ABI over 20 years of age and analyzed according to insurance types encompassing National Health Insurance and automobile insurance. The socioeconomic burden of ABI was 4.67, 5.18, and 5.73 trillion KRW (approximately 4,162, 4,612, and 5,106 million USD) from 2015 to 2017 and around 0.3% of Korea's GDP annually. Estimating by disease, the socioeconomic cost was 72.4% for stroke, 18.6% for TBI, and 9.0% for non-traumatic ABI. Calculated by cost component, medical costs and non-medical costs showed a slight increase every year. Through this study, establishment of rehabilitation systems maximizing the health and quality of life for injured persons remain the key public health strategy for ABI to reduce socioeconomic burden and financial policies to support patients should be needed

Pyruvate Dehydrogenase Kinase Protects Dopaminergic Neurons from Oxidative Stress in Drosophila DJ-1 Null Mutants

DJ-1 is one of the causative genes of early-onset familial Parkinson’s disease (PD). As a result, DJ-1 influences the pathogenesis of sporadic PD. DJ-1 has various physiological functions that converge to control the levels of intracellular reactive oxygen species (ROS). Based on genetic analyses that sought to investigate novel antioxidant DJ-1 downstream genes, pyruvate dehydrogenase (PDH) kinase (PDK) was demonstrated to increase survival rates and decrease dopaminergic (DA) neuron loss in DJ-1 mutant flies under oxidative stress. PDK phosphorylates and inhibits the PDH complex (PDC), subsequently downregulating glucose metabolism in the mitochondria, which is a major source of intracellular ROS. A loss-of-function mutation in PDK was not found to have a significant effect on fly development and reproduction, but severely ameliorated oxidative stress resistance. Thus, PDK plays a critical role in the protection against oxidative stress. Loss of PDH phosphatase (PDP), which dephosphorylates and activates PDH, was also shown to protect DJ-1 mutants from oxidative stress, ultimately supporting our findings. Further genetic analyses suggested that DJ-1 controls PDK expression through hypoxia-inducible factor 1 (HIF-1), a transcriptional regulator of the adaptive response to hypoxia and oxidative stress. Furthermore, CPI-613, an inhibitor of PDH, protected DJ-1 null flies from oxidative stress, suggesting that the genetic and pharmacological inhibition of PDH may be a novel treatment strategy for PD associated with DJ-1 dysfunction.
