Purpose: The purpose of this study was to review our experience with the use of self-expandable metallic stents as the initial interventional management for acute malignant large-bowel obstruction. Methods: The records of 35 patients who underwent placement of a colonic stent for acute malignant obstruction at our institution between January 2003 and December 2004 were reviewed. Results: Stents were placed for palliation in 19 patients and as bridge to surgery in 16 patients. Technical success of stent placement was achieved in all patients (100%), but clinical failure occurred in two patients due to limited expansion of the metallic stent. One of them who had clinical failure underwent an emergency operation, and the other needed no further procedure because of his death. Complications occurred in 4 patients (12%), including one pelvic abscess associated with colon perforation, two minor bleedings, and one anal pain. All the patients in the bridge-to-surgery group underwent an elective colon resection without stoma. In the palliative group, stent reocclusion was observed in three patients during the follow-up (median: 65 days; range: 27~440 days), two of which were managed by reinsertion of a stent. In the remaining patients, the stent was patent until death or the last follow up date (median: 65 days). Conclusions: Placement of a self- expandable metallic stent is a safe and effective procedure for immediate decompression of acute malignant large- bowel obstruction. It provides a chance of elective surgery for patients with resectable disease, as well as relief of symptoms for those with unresectable disease.

With the recent increase in the demand for electric vehicles, it is necessary to identify the high current safety of automobile parts. Among the automobile parts, the EPDM parts required colored parts from the existing black; therefore, it was necessary to change the basic filler from carbon black to silica. The rubber used in automobile parts is flexible and exhibits basic characteristics of high strength and elongation. However, as the filler is changed to silica, its physical properties, such as tensile strength and elongation, are lower than those of the existing carbon black base. Therefore, it is necessary to evaluate the mechanical properties with the addition of the EPDM compound using silica as a base without degrading the physical properties of EPDM. In this study, an experiment based on the additive content was performed using the mixture experimental planning method to analyze the mechanical properties according to the additive type and mixing ratio of silica-based EPDM. The mixing ratio of the four additives was set using a simplex lattice design, and the tensile strength, elongation, modulus 300%, and permanent compression reduction rate were analyzed for mechanical characteristics, and rheometer experiments were performed for vulcanization characteristics. Through statistical analysis of the measured data, the main effects and interactions of the EPDM-blended rubber additives were analyzed. These results can be used to derive a mixing ratio of additives that satisfies the required characteristics of the EPDM compound.

장덕조 소설에 나타난 ‘문학소녀’와 ‘여류’ – 「해바라기」(1937)와 「여류 예술가」(1940)를 중심으로

박윤아 한국여성문학학회 2022 여성문학연구 Vol.56 No.-

This paper examines the relationship between the birth of a literary girl and female writers through an analysis of Jang Deok-jo’s short novels Sunflower and Female Artists. The new representation of “literature girls” is the result of the discipline surrounding the daily lives and emotions of female writers. Jang Dukjo’s early short stories effectively reproduce the social identity and on to logical anxiety of “literary woman” as “hysteria.” In particular, these representations are important in that they reveal the possibility of discipline of male-dominated power and there location of gendered emotions. The subject of “literary woman” is born in a pathological state, and women’s resistance and voices are sutured. Colonial literature’s strategy of limiting women’s literary enjoyment and artistic achievement reveals the oppression of the ruling powers that created an environment in which female writers could not grow. This paper is meaningful in that it specifically re-evaluates women writers’ methods of survival, which are inherent in the process of calling summoning “literature girls.” Moreover, it reveals the authoritarian attitudes adopted by colonial women writers in their oppressive daily lives, where, subject to the pressures of dominant discourse, they were forced to awaken. 이 논문은 장덕조의 단편소설 「해바라기」와 「여류 예술가」를 중심으로 문학소녀의 탄생과 여류 작가의 상관성을 고찰했다. 문학소녀라는 새로운 표상은 여성 작가의 일상과 정서를 둘러싼 규율화의 결과다. 장덕조의 두 편의 소설은 ‘문학 하는 여성’의 사회적 정체성과 존재론적 불안의 감정을 히스테리로 효과적으로 재현한다. 특히 남성 중심적 권력의 규율화와 젠더화된 감정의 재배치 가능성을 드러냈다는 점에서 중요하다. ‘문학 하는 여성’ 주체는 병리적 상태에서 탄생하며 여성의 저항과 목소리는 봉합된다. 여성의 문학적 향유와 예술적 성취를 제한하는 식민지 문단의 전략은 여성 작가가 성장할 수 없도록 환경을 조성해 나간 지배권력의 억압성을 드러낸다. 이 논문은 문학소녀의 호명 과정에 내재한 여류 작가의 존재 방식을 구체적으로 재평가하고 식민지 여성 작가들이 지배 담론에 의해 각성을 강요당한 억압적인 일상 속에서 취한 작가적 태도를 드러내고 있다는 점에서 의의가 있다.

Regional Metabolic Changes Influencing Three-Dimensional Perception in Parkinson’s Disease

박윤아,박건우,이찬녕 대한신경과학회 2022 Journal of Clinical Neurology Vol.18 No.4

Background and Purpose Stereopsis refers to the perception of depth and awareness of the distance of an object from the observer that results from the brain receiving visual stimuli from both eyes in combination. Patients with idiopathic Parkinson’s disease (PD patients) typically experience problems with vision, eyeball movements, and visual perception due to degeneration of the cells that generate dopamine in the brain. We therefore hypothesized that stereopsis is affected more by visual cortical dysfunction in idiopathic PD than by retina and subcortical structural dysfunction. Methods We analyzed stereopsis in 12 PD patients and 7 healthy controls using a three-dimensional (3D) television (TV). Before allowing patients to watch TV, we examined their visual acuity and strabismus using the Titmus Stereo Fly Test, and evaluated their cognitive function using cognitive tests. The patients watched 3D and two-dimensional (2D) versions of a movie with an approximate duration of 17 minutes, and then completed a questionnaire about stereopsis. All subjects underwent brain F-18 fluorodeoxyglucose (FDG) positronemission tomography after watching the 3D version of the movie. One week later, subjects watched the 2D version of the same movie under the same conditions. Each scan was analyzed using statistical parametric mapping (version 8) software. Results The visual cortex was activated less in the PD patients than in the healthy controls when watching the 2D or 3D movie. However, there was no significant difference between watching 2D and 3D movies in the PD patients or healthy controls. Conclusions The lower activation of the primary visual cortex in PD patients suggests the presence of dysfunction of the visual cortex. In addition, there was less activation of the visual association cortex in PD patients when watching a 3D movie than in controls under the same conditions. This might be one reason why PD patients do not recognize real and dynamic stereopsis. These findings have clinical significance since they suggest that safety needs to be considered when making devices or programs using 3D or virtual reality for use by patients with various cerebral degenerative diseases

A renal cell carcinoma (RCC) is known for its high propensity for early metastasis. Among the metastatic cancers of the head and neck, RCC is the third most common disease after breast cancer and lung cancer. Head and neck metastasis of RCC occurs mainly in the thyroid gland (36.6%), nose and sinus (9.1%), and lesions in the ear canal and temporal bone are very rare. Although extremely rare, metastatic malignancy in the breast, lung, prostate, kidney to the external auditory canal have been reported in the literature. We report a case of metastatic RCC of the left external auditory canal in a 78-year-old male patient who had experienced multiple organ metastasis after nephrectomy due to renal cell carcinoma.

박윤아,박건우,이찬녕 대한치매학회 2017 Dementia and Neurocognitive Disorders Vol.16 No.4

Background Alzheimer’s disease is a chronic neurodegenerative condition, mostly affecting the medial temporal lobe and associated neocortical structures. In this report, we present a rare clinical manifestation of this disease. Case Report A 61-year-old female with word finding difficulty and memory disturbances was diagnosed with Alzheimer’s disease. Two years later, she complained of right homonymous hemianopia without optic ataxia, ocular apraxia, and simultagnosia. No findings other than parenchymal disease were apparent in magnetic resonance imaging and laboratory tests. Conclusions In this case, in a patient initially diagnosed with Alzheimer’s dementia with progressive disease, we found only homonymous hemianopia, without signs of Balint’s syndrome or Gerstmann’s syndrome. After careful investigation showing that Alzheimer’s dementia with visual symptom was not associated with parenchymal disease, we concluded a case of atypical variant of Alzheimer’s disease.

Optimism as a Mediator of the Relationship between Adolescents’ Stress and Intelligence: Using the K-WISC-V

박윤아,김연수,곽금주 한국인간발달학회 2023 人間發達硏究 Vol.30 No.1

The current study focuses on adolescent intelligence and its relationship with stress and optimism. We aim to examine the mediating role of optimism in the association between stress and intelligence. We conducted a cross-sectional study among 665 South Korean adolescents aged 12-16 years (M = 14.3; SD = 1.4; 47.4% female). Intelligence was assessed by K-WISC-V subtests, and we derived Full-Scale Intelligence Quotient (FSIQ) and five primary index scores (e.g., VCI, VSI, FRI, WMI, PSI) for analyses. Stress and optimism were also measured by self-report questionnaires. Through correlation and mediation analysis, we attained the following results. Stress did not significantly predict intelligence in general, while optimism positively predicted intelligence. Also, optimism mediated the association between stress and FSIQ and the association between stress and primary index scores except for PSI, after controlling for sex and region. The current study is the first empirical attempt to clarify the pathway from stress to intelligence among adolescents by revealing that stress indirectly affects intelligence through optimism. In this way, we provide direction for further discussions on how to protect and enhance adolescent intelligence.
