Purpose: Malignant hyperthermia is hypermetabolic disorder of skeletal muscle that manifests during general anesthesia. Strabismus and ptosis are important risk factors in ophthalmology field for malignant hyperthermia. We report a case of malignant hyperthermia in patient with partially accommodative esotropia. Case summary: A 6-year-old patient was supposed to undergo a surgical correction for 20 prism diopters of right esotropia after correction of hypermetropia. Because the patient showed tachycardia and hyperthermia just after inhalation of sevoflurane, we interrupted general anesthesia and cancelled the surgery. The patient was transferred to the intensive care unit. In this case, no significant familial and past histories were found. Intractable tachycardia and hyperthermia that had not responded to conservative management improved after two administration of dantrolene sodium. The patient was returned to the ward three days later. As the patient showed no other complication, he was discharged. Conclusions: In malignant hyperthermia, early diagnosis, appropriate management, and prompt administration of dantrolene sodium are important factors for better prognosis. Preoperatively, full explanation of possible complication and history taking are needed. Careful observation is necessary during anesthesia and surgery. J Korean Ophthalmol Soc 49(8):1356-1359, 2008

Purpose: To evaluate the effect of the mixed solution of hyaluronate and sodium carboxymethylcellulose (HACMC, Guardix-sol®) in reducing postoperative adhesion following strabismus surgery. Methods: In 16 rabbits out of 20 rabbits, 3 mm recession of the superior rectus muscle was performed on both eyes and HACMC solution was applied only to one eye which was randomly chosen. The rabbits were divided into a surgery-HACMC group and a surgery-no HACMC group. As a control group, the remaining 4 rabbits had no procedures performed. After 3 weeks, both eyes of 8 rabbits with surgery and 2 rabbits of the control group were enucleated. After staining with hematoxylin-eosin and Masson\'s trichrome, a histologic examination was performed. In the remaining 10 rabbits, the severity of adhesion in muscle and adjacent tissues was observed by blunt dissection. A researcher blind to the experiments performed all the examinations. Results: A significant reduction in the degree of adhesion (P=0.005) as well as decreased fibrosis (P=0.015) was observed in the surgery-HACMC group. Conclusions: The mixed solution of HACMC was effective in reducing postoperative adhesion after strabismus surgery in rabbits.

권성욱(Sung Wook Kwon),송종길(Jong Gil Song) 한국휴먼이미지디자인학회 2023 한국휴먼이미지디자인 Vol.5 No.1

본 연구는 언론의 이념적 성향의 차이가 나타나는 북한 관련 보도의 내용을파악하기 위해 문재인 정부와 윤석열 정부 출범 초기 빅카인즈(BIGKinds)의 뉴스 데이터에서 추출한 주요 키워드를 바탕으로 정량적인 분석을 시행하였다. 연구결과, 첫째, 북한 관련 언론보도는 한․미․중․일 등 주변국과의 외교나 협력,주변국들의 대응에 관한 언급이 많았으며, 모든 언론사의 주요 의제로 설정되었다. 둘째, 문재인 정부 시기 보수신문은 미사일과 대북 제제, 진보신문은 한반도의 평화 등에 대한 언급이 많았다. 셋째, 윤석열 정부 출범 초기 보수신문은 미사일 발사 도발에 대한 강력한 대응, 진보신문은 한반도 평화를 위한 윤석열 대통령과 정부에 대한 적절한 대응을 언급한 것으로 파악되었다. 결과적으로 보수신문은 일관되게 대북제제와 도발에 대한 강력한 대응을, 진보신문은 한반도의평화를 위한 온건한 대응을 주문한 것으로 파악되었다. 본 연구는 언론사의 정치적 지향점에 따라 각기 다른 입장으로 북한에 대한 인식을 유지하고 있는 것으로 파악되었으며, 언론사의 정치적 지향에 따라 달라지는 특정 이슈에 대한 인식이 다르다는 주장을 재차 확인하였다는 데 그 의미가 있다. This study conducted a quantitative analysis based on key keywords extracted from news data from the Moon Jae-In government and BIGKinds in the early days of the Yoon Suk-yeol government's launch to understand the contents of North Korea-related reports that show differences in media. As a result of the study, First, media reports related to North Korea were often mentioned about diplomacy or cooperation with neighboring countries such as South Korea, the U.S., China, and Japan, and the response of neighboring countries, and were set as the main agenda of all media companies. Second, during the Moon Jae-In government, conservative newspapers mentioned missiles, sanctions against North Korea, and progressive newspapers mentioned a lot about peace on the Korean Peninsula. Third, it was found that the conservative newspaper in the early days of the Yoon Suk-yeol government mentioned a strong response to the missile launch provocation, and the progressive newspaper mentioned an appropriate response to the Yoon Suk-yeol president and the government for peace on the Korean Peninsula. As a result, it was found that the conservative newspaper consistently ordered a strong response to sanctions and provocations against North Korea, and the progressive newspaper ordered a moderate response to peace on the Korean Peninsula. This study was found to maintain the perception of North Korea from different positions according to the political orientation of the media, and it is meaningful to reaffirm the claim that the perception of specific issues that vary according to the political orientation of the media.

Surgical resection is the best treatment for operable metastatic liver cancer. Large metastatic cancer usually has low operability, so a debulking modality of mass is needed to increase operability. Chemotherapy and radiotherapy were commonly used as neoadjuvant treatments. Cyberknife stereotactic radiosurgery systems were only considered as one of the palliative treatment modalities for inoperable or surgically complex tumors. But, in this case, we applied Cyberknife as the preoperative debulking modality for large hepatic metastasis of adrenocortical carcinoma. After Cyberknife treatment 3 cycle×2,700 cGY, tumor size decreased (metastatic liver mass decreased to 15×9 ㎝ from 19×12.5 ㎝, adrenal mass decreased to 5×3 ㎝ from 7.4×4.5 ㎝). We could then resect the tumor completely by extended right hemihepatectomy & right adrenalectomy. A preoperative multidisciplinary approach, including chemotherapy and radiation therapy can be considered to increase operability. So, cyberknife can be considered an additional modality as a neoadjuvant radiotherapy.

스플린터(splinter) 및 판상(plate shape) 형상을 가지는 티탄산칼륨염(K₂O·nTiO₂, PT)을 합성하고 브레이크 마찰재의 보강재로 이용하여 마찰 특성을 평가하였다. 스플린터형 티탄산칼륨염을 합성하기 위하여 먼저 판상 형상을 가지는 사티탄산칼륨염(K₂O·4TiO₂, PT4)을 합성하고 칼륨 이온(K⁺)을 일부 산침출(acid leaching)하여 육티탄산칼륨염(K₂O·6TiO₂, PT6)으로 변환시킨 후, 800℃에서 열처리하여 스플린터 형상의 입자를 얻었다. 판상형 티탄산칼륨염을 합성하기 위해서 염화칼륨을 융제로 사용하고 마그네슘(Mg)을 일부 첨가하여 판상의 형상을 가지는 마그네슘티탄산칼륨염(K_0.8Mg_0.4Ti_1.6O₄, PMT)을 합성하였다. 얻어진 육티탄산칼륨염 및 마그네슘티탄산칼륨염 입자를 보강재로 이용하여 브레이크 패드 마찰재를 제작하고 1/ 5-스케일 다이나모미터(scale dynamometer)를 이용하여 마찰 마모 특성을 평가하였다. 평가 결과, 두 종류의 보강재가 유사한 마찰계수 및 Fade & recovery 특성을 보였으며 판상형 마그네슘티탄산칼륨염의 경우, 스플린터형 육티탄산칼륨염보다 우수한 내마모성을 보이는 것을 알 수 있었다. We synthesized potassium titanates having splinter and plate shape and evaluated frictional and wear properties of brake pad using them as reinforcements in friction materials. For splinter-shaped potassium titanates, potassium tetratitanate (K₂O·4TiO₂, PT4) with plate shape was prepared, then K ion of the titanate was leached by acid to make potassium hexatitanate (K₂O·6TiO₂, PT6), which was transformed to splinter-shaped PT6 by thermal treatment at 800℃. Plate-shaped potassium magnesium titanate (K_0.8Mg_0.4Ti_1.6O₄, PMT) was prepared by adding Mg in the potassium titanate using KCl as a flux. Using PT6 and PMT as reinforcements in friction materials of brake pad, we evaluated frictional and wear properties using 1/5-scale dynamometer. According to dynamometer test results, both reinforcements shows similar friction coefficient and fade & recovery behavior to conventional material and plate-shaped PMT exhibits higher wear resistance than splinter-shaped PT6.

各種(각종) 알코올 용매에서 Benzyl Benzenesulfonate와 Pyridine의 四次化(사차화) 反應(반응)

여수동 ( Soo Dong Yoh ),권성욱 ( Sung Wook Kwon ) 경북대학교 과학교육연구소 1989 科學敎育硏究誌 Vol.13 No.-

The reaction rate of Benzylbenzenesulfonate with pyridine was measured in various solvents by conductivity method. The reaction rate was increased by the increment of dielectric constant of aliphatic alcohols. On the while, in acetonitrile, the reaction rates were slow in contrast to dielectric constant. It has been known that the reaction rate is more affected by dissociation of leaving-group rather than bond-fromation of the nuclophile in the transition state. The results suggest that the reaction has dissociative SN2 transition state in aliphatic alcohols.

The Established local government committees are necessary to be examined in local government dimension as well as central government. In this article, the study is continued on two committees, the KwanAk-Ku Traffic Inconvenience Civil Appealing Practical Discussion Committee and the Rural Bus Route Mediation Screening Committee. Most of korean local government committees have nominal roles, but these two committees, the KwanAk-Ku Traffic Inconvenience Civil Appealing Practical Discussion Committee and the Rural Bus Route Mediation Screening Committee can suggest that citizen participation can be achieved during this participation procedure. And citizen participation in decision making can affect on policy making. In spite of positive side, it can be said that it also has some problems of representative problem, professionalism, committee member's ratio problem etc. All these problems should be cured ultimately because, citizen growth can be acquired these kind of lots of participation.
