The purpose of this study was to contribute to the medical treatment of subdural effusion through clinical sequence analysis of patients who experienced improvement of subdural drainage and had a second operation for subdural drainage or subduroperitoneal shunt. Sixteen cases of the whole patients who have been underwent subdural effusion and subdural drainage were analyzed during the period from 2006 July to 2012 June. The study gave us a result that all of patients, who was taking aspirin, have been under the second operation(p<0.001) and these group have had a subduraoperitoneal shunt(p=0.014)). According to the comparative analysis for the patients group that divided into two; one had subduroperitoneal shunt and the other had no subduroperitoneal shunt, the outcomes of this study were shown as follows. First, their median line deviation was serious in their brain CT. In addition, their subdural effusion increased or did not change with a headache, vomiting, fever and dyspnea. As a result of those symptoms. subduraoperitoneal shunt was carried out(p=0.006). The surgical method for patients who were taken asprin must be cautiously selected and the prevention of sudden disappearance of cerebrospinal fluid and excessive change of intracranial pressure is very important in operation craniectomy.

Recently, the invasion of privacy in medical information has been issued following the interest in the secondary use of mass medical information. The mass medical information is very useful information that can be used in various fields such as disease research and prevention. However, due to privacy laws such as the Privacy Act and Medical Law, this information, including patients' or health professionals' personal information, is difficult to utilize as a secondary use of mass information. To do these problem, various methods such as k-anonymity, l-diversity and differential-privacy that can be utilized while protecting privacy have been developed and utilized in this field. In this paper, we discuss the differential privacy processing of the various methods that have been studied so far, and discuss the problems of differential privacy using Laplace noise and the previously proposed differential privacy. Finally, we propose a new scheme to solve the existing problem by adding a 1-bit status field to the last column of a given data set to confirm the response to queries from analysts.

This study aimed to identify the effect of resilience and positive psychological capital on hospital nurses' professional quality of life. A cross-sectional survey design was utilized to investigate 221 general hospital nurses from June 1 to 30, 2021. Professional quality of life (ProQOL), which is conceptualized with three sub-dimensions (compassion satisfaction, burnout, and secondary traumatic stress), resilience, and positive psychological capital variables were measured. There was a positive relationship between compassion satisfaction and resilience, positive psychological capital, and a negative relationship among burnout, secondary traumatic stress, and the other variables in this study. The main factors influencing compassion satisfaction were resilience, and positive psychological capital, which explained about 47% of compassion satisfaction. Burnout was influenced by resilience, positive psychological capital, and work pattern, and these variables explained about 37% of burnout. Notably, it was found that resilience was the most crucial factor in nurses' compassion satisfaction, and positive psychological capital was the most crucial factor in nurses' burnout. Thus, it is suggested to develop and verify the effectiveness of a resilience improvement program and positive psychological intervention program to strengthen the internal resources of hospital nurses.

Recently invasion of privacy problem in medical information have been issued following the interest in secondary use of large medical information. These large medical information is very useful information that can be used in various fields such as disease research and prevention. However, due to the privacy laws such as Privacy Act and Medical Law, these informations including patients or health professionals' personal information are difficult to utilize secondary. Accordingly, various methods such as k-anonymity, l-diversity and differential-privacy that can be utilized while protecting privacy have been developed and utilized in this field. In this paper, we study differential privacy processing procedure, one of various methods, and find out about the differential privacy problem using Laplace noise.

콩은 중요한 식량 작물로 단백질, 기름 및 이차대사산물인 이소플라본을 다량으로 함유하고 있다. 이소플라본은 폴리페놀의 일종으로 일부 암을 예방하며 심혈관 질환을 완화하는 데에도 도움을 준다고 알려져 있다. 콩에 인위적으로 식물호르몬인 ABA를 처리할 때 이차대사산물인 kaempferol의 함량이 증가한다고 보고 되었다. 따라서 이 연구는 식물 생장조정제 처리가 콩잎의 이소플라본 함량에 미치는 영향을 알아보기 위해 수행되었다. 연구는 밀양 남부작물부 유리온실에서 수행되었으며, 콩(품종:선풍)은 와그너포트 1/2000에 1주 2본 파종하여 재배하였다. Ethephone(500, 1000, 2000 ppm)과 ABA(100, 200, 400 ppm)를 사용하였으며 각각 R2, R5, R7기에 처리하였다. 처리 후 잎을 5일 간격으로 3회 채취하여 이소플라본 6종과 쿠메스트롤의 함량을 분석하였다. 초고성능 액체 크로마토그래피(Acquity UPLC H-Class system, Waters)를 사용하여 분석하였다. 이소플라본 함량은 R5 단계에서 전반적으로 높게 나타났으며, R2 및 R7 단계에서는 무처리와 유사한 수준을 보였다. ABA를 처리하였을 때 생장조정제 간의 차이가 에테폰보다 더 큰 것으로 나타났다. 쿠메스트롤 함량은 처리시간에 따라 R7, R5, R2 순으로 높은 것으로 확인되었으며, 처리시간이 지날수록 함량이 증가함을 알 수 있었다. 생장조정제 처리에 쿠메스트롤 함량은 ABA보다 에세폰 처리 시 더 높은 경향을 보였다.

Background: We analysed simple chest PA and high-resolution CT findings in patients with spontaneous pneumothorax in order to help selecting the kind of treatment, provide a guidline during surgical treatment, and to recognize the bulla which may not be detected by simple radiographs or may be a potential cause of recurrence. Material and Method: We retrospectively analysed the presence and number of bulla in each side, combined pulmonary disease on simple chest films and high-resolution CT, and methods and frequency of the treatment in 70 patients with spontaneous pneumothorax excluing traumatic origin. Result: 45 patients were revealed primary spontaneous pneumothorax, and the remaining 25 patients were revealed secondary spontaneous pneumothorax. All secondary spontaneous pneumothorax were from the longstanding sequelle of pulmonary tuberculosis. The patients with primary spontaneous pneumothorax group was younger(mean:26.0 years old) than secondary group (mean: 44.1 years old). On simple radiography, bulla was detected in 16 patients(30.2%). On HRCT, the bulla was detected in 53 patients(75.7%) of the total 70 patients. In 48 patients(68.6%), the bulla or bleb was noted in ipsilateral side to the pneumothorax, and 34 patients(48.6%) of them showed bulla or bleb bilaterally. 39 patients(55.7%) showed bulla or bleb in contralateral side. The number of bulla or bleb was variable. In secondary spontaneous pneumothorax group, the incidence of multiple(more than 10) bulla or bleb was higher than primary type. Most of the patients were treated by thoracostomy(36 patients) or bullectomy( 7 patients). Conclusion: HRCT was superior to detect bulla and analyse the combined pulmonary disease than simple radiography. Therefore, HRCT can help to determine the mothod of treatment, provide a guidline during surgical treatment, and notify the bulla as a possible cause of recurrent pneumothorax.

This study investigated the effects of silver diamine fluoride (SDF) and potassium iodide (KI) treatments on the acid resistance of dentin exposed to secondary caries. Sixteen bovine dentin specimens with artificially induced caries were assigned to the following four groups: untreated negative control, untreated positive control, SDF-treated (SDF), and SDF and KI-treated (SDFKI). Multispecies cariogenic biofilms containing Streptococcus mutans, Lactobacillus casei, and Candida albicans were cultured on the specimens for 28 days, except for the negative control group. Specimens from the negative control group were stored in phosphate-buffered saline for that period. After a cariogenic biofilm challenge, the degree of demineralization was evaluated using micro-computed tomography (micro-CT). As a result of data analysis using micro-CT, the demineralization depths of the negative control, positive control, SDF, and SDFKI groups were 149.0 ± 7 ㎛, 392.0 ± 11 ㎛, 206.0 ± 20 ㎛, and 230.0 ± 31 ㎛, respectively. The degree of demineralization was significantly reduced in the SDF and SDFKI groups compared with that in the untreated positive control group. There were no significant differences between the SDF and SDFKI groups. This study confirmed that SDF and SDFKI treatments increase the acid resistance of dentin to secondary caries. KI did not significantly affect the caries-arresting effect of the SDF.

The purpose of this study was to obtain available data concerning tuberculosis control at health center and to recommend more effective measures to government and antituberculosis agencies. The study showed following results: Registration of tuberculosis patients should be allowed all patients regardless the extension of lesions. It is necessary that those patients who have not response to primary anti-tuberculosis drugs should be treated by secondary drugs. Control measure should be applied to those patients who discharged from health center in the past because more than 50 percent of them were still active situation. Meaningless mass X-ray survey should be abandoned and limited to family-contacts.

A person with neurological disorder is defined as a person with limitation of ambulation or basic life activity due to the cerebral palsy or traumatic brain damage, stroke. Recently, the DMFT of the children with neurological disorders is similar or lower than the DMFT of the children with no disability. But, this article is about the severe-early childhood caries in children with grade 1 neurological disorder. It is supposed that the primary motor impairment and secondary physical weakness, frequent hospitalization, sugar- rich food and drugs, lack of oral care, delayed dental visit made high caries susceptibility. In case of treatment of the children with severe neurological disorders, dentists should make a thorough caries preventive plan based on individualized caries risk assessment. Also parents and medical doctors should recognize the importance of oral care and do the early dental visit and home care.
