정성태,손주태,최승호,윤명하 대한마취통증의학회 2011 Anesthesia and pain medicine Vol.6 No.4

Background: There is increasing evidence that more aggressive pain management is needed in patients undergoing craniotomy in Korea. However, no consensus or standardized analgesic regimen has been established to date. To achieve this consensus, we undertook a survey of the current state of post-craniotomy pain management in Korea. Methods: A postal questionnaire was sent to anesthesiologists,neurosurgeons and nurses of neurosurgical departments at 44university hospitals in Korea. Of the 44 centers that were sent questionnaires, 35 centers returned these from their anesthesiology department resulting in a response rate of 73%, and 25 returned the questionnaires from their neurosurgery department (response rate: 57%). Results: Fifty-three percent of neurosurgeons answered that current postoperative pain management was adequate after craniotomy,whereas only 8% of anesthesiologists agreed. However, 72% of neurosurgeons also agreed that a more aggressive pain management was needed for post-craniotomy patients. Fifty-two percent and 23% of neurosurgeons used non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen as a first-line analgesic,respectively. Twenty-five percent of neurosurgeons used opioids as a first-line analgesic. Fifty percent of anesthesiologists used strong opioids alone or with NSAIDs as a first-line analgesic. About 10% of both groups used weak opioids as a first-line drug. Conclusions: Many clinicians agree that post-craniotomy pain is not adequately managed and more aggressive strategies are needed. Nevertheless, opioid analgesics are still avoided because of the concern of side effects despite no evidence to suggest increased risk when use carefully.

The purpose of paper is to investigate the characteristics of regulations on landscape management of historic city of Kyongju in Korea, compared with those of Nara in japan to answer the research question that what is the regulative characteristics of landscape management of historic city in Korea. We have analyzed the three laws of the two country - Urban Planning Law, Cultural Assets Protection law, and Building Law. This research has been done in terms of regulative systems of the two country and articles, ordinances, and bylaws on landscape managements of historic city Major components of urban historic landscape management are goals and devices of preservation, preserving actor, authorized actor permitting major planning change, regulatory power on landscape development, and backgrounds of enacting regulations. From this research, we have fond the fact that 1) Kyongju City has general and implicit objectives of landscape management based on conservation of natural environment while Nara City has concrete objectives of lansdscape management, 2) Kyongju City has no regulations on landscape planning while Nara City has systematic planning measures such as designation of landscape management district, planning for preservation of historic landscape, and planning for establishing urban landscape, 3) In an application of landscape management district, Kyongju City designate the district based on the general principle of urban planning district while nara City designate it in a more detailed manner such as district of preservation of historic landscape, district of landscape establishment, and district of building agreement. 4) Kyongju has no legal actor in implementation and management of historic landscape plan while Nara City has administrative organization and procedures, including citizen participation, public hearing, and voluntary participation, and 5) Kyongju City does not operate the consultation committee on landscape management just like Nara City operating. This research results will provide us the remedial insights for landscape preservation of such Korean historic city as Kongju, Puyo, and Chunju. Since our research is focused on the limited area of preserving landscape in historic cities in korea and Japan we need to study sociocultural issues on preserving urban historic landscape more in depth in the future.

정성태,김연수,이왕록,박익렬,강현주 서울대학교 체육연구소 2001 서울大學校 體育硏究所論集 Vol.22 No.1

The purpose of this present study was to investigate the effect of maximal exercise and a long-term antioxidants supplementation on antioxidant enzyme(GPx and GR) activity of gastrocnemius muscle in rats. Twenty four male Sprague-Dawley rats(4 weeks old) were used as subjects. The subjects were divided into 4 groups such as, CON(n=6 in control group), NAE(n=6 in non antioxidants exercise group), AC(n=6 in antioxidants control group) or AE(n=6 in antioxidants exercise group). Non-antioxidants group(CON & NAE) fed general food(Samyang, Inc., Korea) for 16 weeks. Antioxidants group(AC & AE) fed the general food and the mixed antioxidants which were consist of vitamin E(200 lu/kg/day), vitamin C(50 mg/rat/day), vitamin B6(250 ug/kg/day), β carotene(300 mg/kg/day) and selenomethionine(0.1 mg/mg/day), The weight of each subject group was weighed 2-3 times per week. After the diet experiment for 16 weeks, exercise groups(NAE & AE) completed acute treadmill running(speed increased gradually to 25 m/min, 15% uphill grade, ∼50±10 min) until exhaustion. Immediately after exhaustive treadmill exercise, all the subjects were sacrificed for the isolation of gastrocnemius. Then, GPx(Glutathione Peroxidase) and GR(Glutathione Reductase) of the gastrocnemlus muscle were assayed. The protein concentration in the muscle and heart was determined by the Lowry method. After finishing the analysis of antioxidant activity, statistical analysis was carried out by two-way ANOVA and independant t-test. The results of this study can be summarized as follows: Maximal exercise increased the GPx and GR activity of gastrocnemius muscle, Further, a long-term antioxidants supplementation more significantly increased the GPx and GR activity of gastrocnemius muscle than those of non-antioxidants group. In conclusion, the present results clearly show that the exhaustive maximal exercise gave rise to increase oxidative stress which led to oxidative damage so that the antioxidant enzyme activity of gastrocnemius muscle were increased. Further, it has been found that the long-term antioxidants supplementation could decrease oxidative stress in the tissues so that the antioxidant enzyme activity of skeletal muscles was more increased.

정성태,송지아,이성헌,최정일,이형곤,박수연,황정연,박상희 대한마취통증의학회 2019 Anesthesia and pain medicine Vol.14 No.2

Background: Postoperative sore throat (POST) is a common adverse event after general anesthesia. The aim of this study was to evaluate the effectiveness of 2% lidocaine jelly applied on the single-lumen endotracheal tube (ETT) and thermal softening of the ETT, and a combination of both interventions on the development of POST. Methods: Patients (n = 144) undergoing general anesthesia were randomly assigned to one of four groups: Control group (un-softened ETT lubricated with saline); Lidocaine group (un-softened ETT lubricated with 2% lidocaine jelly); Softened group (thermally softened ETT lubricated with saline); and Combined group (thermally softened ETT lubricated with 2% lidocaine jelly). Sore throat was evaluated at 0, 1, 6, 24, and 48 h after extubation. The occurrence of any postoperative complication was also assessed including hoarseness and coughing. Results: No significant difference was observed in the severity of POST at all time points. However, the incidences of POST for overall (0–48 h) and the immediately following period (0 h) were significantly lower in the Combined group (52.9% and 47.1%) than in the Control group (79.4% and 76.5%), Lidocaine group (81.8% and 78.8%), and Softened group (82.9% and 74.3%). The overall incidence of hoarseness did not differ among the groups. No other postoperative complication was observed in any of the patients. Conclusions: No differences were observed in the severity of POST. However, 2% lidocaine jelly applied on thermally softened ETT reduced the overall incidence of POST. Therefore, this combined intervention could be considered as an alleviating strategy for POST.

저 전력 비동기 가산기의 설계

정성태 圓光大學校 1996 論文集 Vol.32 No.2

본 논문에서는 Differential Cascade Voltage Switch Logic(DCVSL)에 의거한 비동기가산기를 제안한다. 기존의 동기 가산기는 산술 연산의 데이터 종속성을 이용하지 못하고 모든 연산에 같은 시간, 즉 연산의 경우 중에서 가장 긴 시간을 소요하지만 본 논문에서 제안하는 가산기는 산술 연산의 데이터 종속성을 효과적으로 이용함으로써 평균속도로 동작한다. 또한 본 가산기를 구성하는 소자들은 필요한 경우에만 동작하므로 필요 유무에 관계없이 항상 동작하는 동기 회로에 비하여 전력 소모량을 줄일 수 있다. This paper presents a design of an asynchronous adder based on differential cascode voltage switch logic. Synchronous adders operate on the worst-case time because they can't utilize the data dependency. In contrast, the suggested adder operates on the average-case time by utilizing the data dependency effectively. Also, the transistors of the suggested adder consume power only when it is necessary because the adder is asynchronous. Therefore the power consumptions is very lower than the synchronous adders.
