This study was conducted to identify the level of work stress (School Violence Processing process, teacher role, daily life) and experiences of infringement of teacher authority of elementary and secondary school violence teachers in A city, and to find countermeasures for this. First of all, we produced a stress measure for school violence work based on prior research and derived the investigation process (4 factors, 15 questions), teacher role (3 questions), and daily life (3 questions) through verification and exploratory factor analysis. The analysis results of 125 elementary and middle school teachers showed stress levels in the order of teacher role (4.0), daily life (3.7) and case investigation process (2.9) and secondary teachers were higher. 72.8% (91 people) of elementary and middle school teachers experienced violations of teachers' rights, and middle school teachers experienced more serious violations of teachers' rights. The suggestions of this study are as follows. First, the personnel system needs to be reorganized to create conditions where teachers in charge of school violence can focus on the role of teachers and policy support to resolve difficulties in the issue process. Second, it is necessary to prepare and formalize personnel placement and work guidelines for daily life. Third, legal countermeasures should be taken to prevent infringement of teachers' rights in the school violence process. Fourth, restorative life education should be provided to revive the educational function of the school.

Iron is critical for almost all living organisms because it serves as a cofactor for many proteins and enzymes necessary for oxygen and energy metabolism. Disruption of iron homeostasis is associated with a wide range of diseases. Thus mammals have developed sophisticated mechanisms to maintain optimal range of iron concentration. Iron regulation involves processes at the systemic and cellular levels. These processes are regulated by hepcidin and iron regulatory proteins. Hepcidin modulates systemic iron homeostasis with ability to impede cellular iron export via interaction with the iron export protein, ferroportin. Whereas, iron regulatory proteins control cellular iron homeostasis by translational regulation of proteins which involve iron metabolism. Recent advances in the study of iron metabolism have shown promising results that hepcidin-targeted strategies may help to improve the diagnosis and treatment of iron related diseases. Although these strategies are now under development, ongoing studies can help to elucidate its application possibilities.

발작성 운동유발 운동이상증에 대한 임상적 고찰

서진경,문혜현,권순학 대한소아신경학회 2012 대한소아신경학회지 Vol.20 No.2

목 적 : 발작성 운동유발 운동이상증은 긴장상태 또는 스트레스를 받는 상황에서나 휴식후 갑자기 움직이려고 할 때 신체의 일부분에서 운동이상증을 보이는 경우에 진단할 수 있으며 대부분 항경련제에 반응을 잘하는 양성질환이다. 본 연구는 한국인 소아청소년에서 발작성 운동유발 운동이상증의 임상양상 및 치료에 대한 반응을 분석하기 위해 시행되었다. 방 법 : 2000년 1월부터 2011년 9월까지 경북대학교병원 소아청소년과에 긴장이상증 또는 무도증을 주소로 방문한 25명 중 발작성 운동유발 운동이상증으로 진단받고 약물치료 중인 총 7명의 환아를 대상으로 후향적 조사를 시행하였다. 결 과 : 총 7명의 환아의 평균연령은 15.7(10.0-21.4)세였으며 평균발병연령은 13.5(10.2-16.8)세였고 성별은 6명이 남자, 1명이 여자로 남자가 많았다. 모든 환아에게서 증상은 긴장이상증으로 나타났으며 증상지속시간은 평균 초로 10.5(3.5-17.5)1분 미만이었고 동반이환은 없는 상태로 가족력에도 특이소견이 없었다. 기본적인 혈액검사 및 신경학적 진찰, 뇌파검사에서는 모두 정상소견을 보였고, 1명에게 시행한 근전도검사 및 신경전도검사에서도 정상소견을 보였다. 약물치료를 거부한 1명의 환아를 제외한 6명의 환아에서 약물치료에 반응을 보여 현재는 증상이 없는 상태로 지내고 있었으며 약물치료에 반응하기까지의 시간은 평균 주 3.4(0.95-7.81)가 걸렸다. 치료는 4명의 환아에게 oxcarbazepine를 사용하였고 4명의 환아에게는 lamotrigine을 사용하였으며 두 환자군을 비교 분석한 결과 두 집단간 연령, 발병연령, 증상이 조절되는데 걸린 시간에는 차이가 없었으나 평균 투여용량에서 lamotrigine은 1.5±0.9 mg/kg/day, oxcarbazepine은 14.9±5.8 mg/kg/day로 lamotrigine을 사용했을 때도 비슷한 효과를 얻을 수 있다는 결론을 얻었다. 결 론 : 본 연구를 토대로 한국인 소아청소년에서의 운동유발 운동이상증은 외국에서 선행된 연구들 에서와 큰 차이가 없음을 알 수 있었고 또한 통상적 으로 사용하는 외에도 oxcarbazepine lamotrigine이 적은 용량으로 비슷한 치료효과를 얻을 수 있다는 결과를 확인하여 치료약제 선택의 폭을 넓힐 수 있었다. Purpose : Paroxysmal kinesigenic dyskinesia (PKD) is one of the movement disorders in which dyskinesia occurs in a part of the body by a sudden movement after a rest under a tension or a stress. This study was aimed to evaluate the clinical features of children and adolescents with PKD in Korea via analysing the patients who have treated in Department of Pediatrics, Kyungpook National University Hospital. Methods : A total of seven children with PKD was involved in the study and their medial records were retrospectively evaluated. Results : The mean age of the 7 subjects was 15.7 years (10.0-21.4 years old). The male to female ratio was 6:1. They presented with dystonia with the average duration of 10.5 seconds (3.5-17.5 seconds), which triggered by various sudden movements. No accompanying cormorbidities were noted. Their laboratory findings were unremarkable. Six of the patients, except one who refused treatment with medicine, responded well to medication and remained symptom free. The average time response to medication was 3.4 weeks (0.95-7.81 weeks). They were of treated with either oxcarbazepine (n=4, 14.9±5.8 mg/kg/day) or lamotrigine (n=2, 1.5±0.9 mg/kg/day). There was no significant difference between two groups in terms of age, response, adverse events, and so on. Conclusion : This study showed that clinical features of Korean children with PKD are quite similar to those of other countries. They responded well to the medication. In addition, lamotrigine can be an alternative choice for the treatment.

Background and Objectives Overexposure to intense sound can cause temporary or permanent hearing loss. Post-exposure recovery of thresholds has been assumed to indicate reversal of damage to the inner ear without persistent consequences for auditory function. However, there was a report that acoustic overexposures causing moderate temporary threshold shift caused acute loss of afferent nerve terminals and delayed degeneration of the cochlear ganglion cells while cochlear sensory cells were intact. The purpose of the study was to evaluate the numerical changes of ribbon synapses and efferents to the outer hair cells in ears with temporary noise-induced threshold shifts. Materials and Methods Four-week old CBA mice with normal Preyer’s reflexes were used. Mice were exposed to white noise of 110 dB SPL for one hour. Auditory brainstem response (ABR) and distortion-product otoacoustic emission (DPOAE) were recorded before exposure and at four different post-exposure times, 1, 3, 5, and 7 days after noise exposure. Ribbon synapses and efferents near cochlear nerve terminals were stained and calculated in the control group mice at two post-exposure times, 3 and 5 days after the exposure. Results In the noise-exposed ears, there was no loss of hair cells, in either inner hair cells or outer hair cells. ABR and DPOAE showed maximum threshold shifts after noise-exposure; they returned to the normal pre-exposure values by at day 5. The number of ribbon synapses tended to decrease at 3 days after noise-exposure, but the number of efferent fibers was not statistically different from those of the control mice. Conclusion Our results suggest that the loss of ribbon synapses could be related with the recovery course of temporary threshold shift, even to the point of full hearing recovery.

Purpose The presentations and geographic incidence of pediatric non-Hodgkin lymphoma (NHL) differ from those of adults. This study delineated the characteristics and outcomes of pediatric NHL in East Asia. Materials and Methods Medical records of 749 pediatric patients with NHL treated at participating institutions in mainland China, Japan, Korea, and Taiwan from January 2008 to December 2013 were reviewed. Demographic and clinical features, survival outcomes, and putative prognostic factors were analyzed. Results Five hundred thirty patients (71%) were male. The most common pathologic subtypes were Burkitt lymphoma (BL) (36%). Six hundred seven patients (81%) had advanced diseases at diagnosis. The 5-year overall survival and event-free survival (EFS) rates were 89% and 84%. The 5-year EFS rates of BL, lymphoblastic lymphoma, and diffuse large B-cell lymphoma were 88%, 88%, and 89%, and those of anaplastic large cell lymphoma (ALCL) and peripheral T-cell lymphoma (PTCL) were 71% and 56% (p < 0.001). Central nervous system involvement, high lactate dehydrogenase level (> 250 IU/mL), and advanced disease at diagnosis ( stage III) were associated with poor outcomes (p < 0.05). ALCL and PTCL relapsed more frequently than other pathologic subtypes (p < 0.001). Conclusion In East Asia, PTCL was more frequent than in Western countries, and bone marrow involvement did not affect treatment outcome. This international study should motivate future collaborative study on NHL in East Asia.

날씨 데이터를 활용한 쌀 생산량 예측모델의 특성 선택 및 최적시기탐색 연구

서진경(Jin-Kyeong Seo),최다정(Da-Jeong Choi),백주련(Juryon Paik) 한국컴퓨터정보학회 2023 韓國컴퓨터情報學會論文誌 Vol.28 No.7

쌀 생산량 예측의 정확성을 높이기 위한 대다수의 연구는 모델의 정확도 증진에 초점이 맞춰져 있다. 이에 비해, 예측 모델을 적용할 대상 데이터 자체에 관한 연구는 상대적으로 미흡하다. 쌀 생산량 데이터에 동일한 종속변수와 예측 모델을 사용하여 다른 특성들로 구성된 두 부류의 데이터에 적용하면, 결과의 차이가 발생하는데 이때 어느 데이터 셋이 더 우수한지 판단하기는 어려운 일이다. 이러한 문제를 해결하기 위해, 예측 모델 적용 전에 데이터 내에서 예측 결과에 큰 영향을 미칠 가능성이 있는 특성들을 선별하고, 이를 중심으로 모델링을 수행하면, 데이터의 구성이 다르더라도 안정적인 예측 결과를 얻을 수 있을 것이다. 본 연구에서는 기상청의 종관기상관측(ASOS) 데이터를 활용하여, 쌀 생산량의 안정적이고 일관된 예측을 위해 데이터 구성 특성들의 조정을 통해 최적의 기반 변수를 선별하는 방법에 대해 제안한다. 본 연구의 결과는 향후 다른 연구에서 성능평가의 유용성을 높이는 데 기여할 것으로 기대한다. Various studies to enhance the accuracy of rice production forecasting are focused on improving the accuracy of the models. In contrast, there is a relative lack of research regarding the data itself, which the prediction models are applied to. When applying the same dependent variable and prediction model to two different sets of rice production data composed of distinct features, discrepancies in results can occur. It is challenging to determine which dataset yields superior results under such circumstances. To address this issue, by identifying potential influential features within the data before applying the prediction model and centering the modeling around these, it is possible to achieve stable prediction results regardless of the composition of the data. In this study, we propose a method to adjust the composition of the datas features in order to select optimal base variables, aiding in achieving stable and consistent predictions for rice production. This method makes use of the Korea Meteorological Administrations ASOS data. The findings of this study are expected to make a substantial contribution towards enhancing the utility of performance evaluations in future research endeavors.
