권준호,김은경,곽진영,윤정현,김민정,문희정 대한초음파의학회 2011 ULTRASONOGRAPHY Vol.30 No.3

Metastasis of signet ring cell gastric carcinoma to the breast is extremely rare. The common clinical findings are redness, edematous skin and pain, and these findings are similar to those of inflammatory breast cancer. We describe here a case of metastatic signet ring cell gastric carcinoma to the bilateral breasts, and this presented as bilateral palpable breast lumps after the patient had undergone radical total gastrectomy two years previously.

권준호,전연수,염춘호 한국정보통신학회 2022 한국정보통신학회논문지 Vol.26 No.2

With the development of technology, driving simulators have been used in various ways. In driving simulator experiments, scenario creation is essential to increase fidelity, achieve research aims, and provide an immersive experience to the driver. However, challenges remain when creating realistic scenarios, such as developing a database and the execution of scenarios in real-time. Therefore, to create realistic scenarios, it is necessary to acquire real-time data. This study intends to develop a method of acquiring real-time weather and traffic speed information for actual, specific roads. To this end, this study suggests the concatenator for dynamic data obtained from Arduino sensors and public open APIs. Field tests are then performed on actual roads to evaluate the performance of the proposed solution. Such results may give meaningful information for driving simulator studies and for creating realistic scenarios. 기술발전에 따라 드라이빙 시뮬레이터는 다양한 용도로 활용되고 있다. 드라이빙 시뮬레이터 실험에서 시나리오 개발은 실험결과의 신뢰를 높이고 연구목표를 달성하며 운전자에게 보다 실제같은 경험을 제공하는데 필수적이다. 그러나 시나리오를 개발하는데 데이터베이스 형성과 실시간 시나리오 운영 등에는 아직도 제약이 많다. 본 연구는 이러한 환경에서 실제 도로에서 실시간 주행속도와 기상데이터를 수집하고 활용하는데 가능성을 확인하고자 한다. 또한 본 연구를 통해 아두이노 센서 데이터와 공공API 데이터를 연계하는 방안도 제시하고자 한다. 연구결과의 검증을 위해 실제도로에서 시험을 실시했으며 본 연구를 통해 드라이빙 시뮬레이터에서 실시간 데이터를 활용한 시나리오 개발에 도움이 될 것으로 기대한다.

자전거 이용자를 위한 일회용 미세먼지 마스크 디자인 연구

권준호 한국디지털정책학회 2018 디지털융복합연구 Vol.16 No.12

Bicycle riders complain of many inconveniences when wearing glasses, sunglasses and masks. The disposable fine dust mask has been developed to resolve such inconveniences of bicycle riders. The scope of research is limited to the fiber which generates one-time static electricity and the shape of the mask due to the characteristic of fine dust mask. The purpose is to design and make the fine dust mask with a simple production process. The new disposable fine dust mask has secured enough space of the mask in front of the mouth by longitudinal folding and minimized stuffiness by maintaining the shape of the folded part to prevent touching the mouth even by heavy breathing. The streamlined sponge is attached at the part of nose support and the area of the cheek has been expanded to be about 2.5cm wider than ordinary masks to improve tight seal at the side. In addition, a new disposable fine dust scarf mask has been developed to block ultraviolet rays for the face and neck while filtering fine dust with the tight fine dust mask. 자전거 이용자가 안경 및 선글라스를 쓴 상태에서 마스크를 착용 할 때 여러 가지 불편함을 호소한다. 본 논문은 이러한 불편함을 보완하여 자전거 라이더들에게 필요한 일회용 미세먼지 마스크를 개발하는데 그 목적이 있다. 미세먼지 마스크의 특성상 일회성 정전기 발생 섬유와 마스크의 형태적 문제로 연구범위를 제한하고 기존 미세먼지 마스크를 간결한 제작공정으로 디자인한다. 이렇게 개발된 일회용 미세먼지 마스크는 세로방향 접힘으로 입 앞 마스크 내 공간을 충분히 확보하였고 거친 숨에도 입에 닿지 않게 접힘 부위형태가 유지 되게 하여 답답함을 최소화 하였다. 코지지대에 유선형 스폰지를 부착하고 안면 볼 부위를 일반마스크 보다 2.5cm 정도의 확장하여 측면 밀착성을 높였다. 또한 기존에 없던 일회용 미세먼지 스카프 마스크를 제작하여 안면과 목 부위 자외선을 차단하고 밀착성 높은 미세먼지 마스크를 개발하였다.

鼻茸患者에 있어서 IgE値 및 末梢血液好酸球의 變化

權俊浩,池東夏,曺恩卿,曺台煥,성창섭 慶北大學校 醫科大學 1985 慶北醫大誌 Vol.26 No.1

1983年 7月부터 1984年 6月까지 慶北大學校 醫科大學 附屬病院 耳鼻咽喉科에서 手術을 받은 鼻茸患者 60例 및 慢性副鼻洞炎患者 30例에서 알레르기 檢査, 血淸 IgE値, 鼻茸液 IgE値, 末梢血液好酸球値를 檢査하여 이들의 相互關係를 比較 檢討한 結果 다음과 같은 結果를 얻었다. 鼻茸液 IgE値는 상당히 增加되어 있었으며 특히 알레르기 집단에서 더욱 높았다. 血淸 IgE値는 鼻茸患者群이 대조군인 副鼻洞炎患群보다 약간 높았으며 알레르기 집단과 非알레르기 집단간에도 약간의 차이가 있었다. 鼻茸患者群중에서 병해 病歷 및 알레르기 皮膚反應檢査陽性인 患者는 10名(16.7%)이었다. 末梢血液好酸球增多는 鼻茸患者群에서 조금 높았다. 이상의 結果를 종합하여 볼 때 鼻茸의 발생기전에 알레르기가 여러 요인중 일부를 담당한다고 사료된다. From the survey of relationship between nasal polyposis and nasal allergy the IgE content was measured in serum and nasal polyp fluid of 60 patients with nasal polyp who had admitted to Kyungpook medical hospital during last one year. The IgE content in serum was also measured in patients with chronic paranasal sinusitis who had chosen as control group. In addition, all patients were studied for peripheral blood eosinophil counts. The results were as follows: The level of IgE in polyp fluid was higher than serum level. The IgE content of serum was somewhat higher in nasal polyp patient especially in allergic group than paranasal sinusitis group. Nasal polup patients with allergic history and positive skin test were obtained in 10 cases(16.7%) which was higher than the levels of chronic paranasal sinusitis. Peripheral blood eosinophil was higher in patient with nasal polyp than patient without nasal polyp. As above results it seems that allergy is one of factors which contribute to the development of nasal polyp.

Synthesis and Characterization of Dialkoxynaphthalene-based New π-Conjugated Copolymer for Photovoltaic Solar Cell

권준호,여현동,이민정,박현태,박진희,박찬언,김윤희 한국고분자학회 2011 Macromolecular Research Vol.19 No.2

A π-conjugated dialkoxynaphthalene-based donor-acceptor copolymer was synthesized by a Suzuki coupling reaction, and its photophysical, thermal and electrochemical properties and photovoltaic characteristics were characterized. The copolymer showed good solubility and a weight average molecular weight of 11,500. The new copolymer was characterized by two absorption bands at 315 and 403 nm in the dilute solution, which were assigned to the π→π* transition and an intramolecular charge transfer band, respectively. The wide band gap of the donor-acceptor copolymer was explained by the 3-dimensional structure and tortional angle between the dialkoxynaphthalene and benzothiadiazole of the model compound. The PCE of the photovoltaic solar cell device fabricated using this copolymer reached 0.06% with a Voc, Jsc, and FF of 0.59, 0.3, and 33%, respectively.

Photo-Crosslinked Polymer Cubosomes as Recyclable Nanoreactor in Organic Solvents

권준호,김경택 한국고분자학회 2021 한국고분자학회 학술대회 연구논문 초록집 Vol.46 No.1

Polymer cubosomes are an emerging class of porous structures formed by the self-assembly of BCP with asymmetric block ratio. The internal nanochannel networks of a cubosome provide a large surface area and internal volume to tether catalysts, which makes this porous structure a promising candidate for nanoreactors. Herein, we report the synthesis of BCPs composed of PEG hydrophilic and p(pFS-co-Sty) hydrophobic block. The pFS groups in the hydrophobic block could be easily functionalized with N3 groups by post-polymerization modification. The binary mixture of branched-linear and catalyst-functionalized linear BCP self-assembled into polymer cubosomes having surface-tethered catalysts, which was crosslinked by UV. We show that the resulting nanoreactors could catalyze the asymmetric aldol reaction at an enhanced rate compared to the homogeneous catalysts. These robust nanoreactors performed the catalysis repeatedly after multiple recycling without losing their efficiency and integrity.
