홍성주,윤창륙,유지원,안종모 대한안면통증∙구강내과학회 2010 Journal of Oral Medicine and Pain Vol.35 No.3

The aim of this study is to determine a relationship between the smoking and the gustation. For that purpose, the survey is about the subjective taste change after smoking compared the electrical taste thresholds by EGM on healthy young Korean men before and after smoking. The results of the electrogustometry showed significant differences between smokers and non-smokers, also between before smoking and directly after smoking in smokers showed significant differences which indicated the immediate, but temporary effects of smoking on the taste thresholds. There were no difference of gustatory function by the amount of smoking and the degree of addiction. Based on the results of this study, further studies will be focused on the difference of gustatory function between before and after smoking using the chemical taste test, and the relationship between change of olfactory and gustation by smoking.

The global changes in protein expression ofSynechocystis sp. PCC6803, a photosynthetic bacteriumfor the production of secondary metabolites as a green cellfactory, were investigated by proteome separation and asubsequent tandem mass spectrometry. Two differentproteome separation techniques, strong cation exchangechromatography and off-gel electrophoresis, were applied. The combination of the two proteome separation techniquesenabled the comparative analysis of the differential regulationof the Synechocystis proteome in response to two differentenvironmental factors, temperature and light. A total of1,483 proteins were identified, which represent over 40%of the genes in Synechocystis. Our data showed that fattyacid metabolism was inhibited by (3R)-hydroxymyristol acylcarrier protein dehydrase (Sll1605) under low temperatureconditions. The expression of UDP-N-acetylglucosamineacyltransferase (Sll0379) and 3-O-[3-hydroxymyristoyl]glucosamine N-acyltransferase (Slr0776), which is involvedin lipopolysaccharide metabolism, was not observed underhigh light conditions. Under high light exposure, proteinsrelated to iron-sulfur metabolism were detected, whichmay be responsible for maintaining the redox potential ofthe photosystem. High light under low temperature causedsevere damage to the photosystem. Some of the responsesto these stresses were similar to those previously reportedfor other photosynthetic organisms. Notably, this studyrevealed the followings: (i) low temperature inhibits fattyacid synthesis; (ii) high light inhibits lipopolysaccharidessynthesis and stimulates the expression of iron-sulfurrelated proteins; and (iii) high light under low temperatureinduces the photorespiratory cycle. The global proteomicanalysis clearly showed that stress conditions such as lowtemperature and/or high light induce cellular metabolismsrelated with the protection of their photosystems in themodel microalga Synechocystis sp. PCC6803.

In most cases, it is difficult to diagnose ulcerative diseases of the mouth, because they have many similar clinical appearance. For the diagnosis of oral ulcerative lesions, the clinician should check a detailed history of the patient and consider the relation with systemic diseases. In this case report, we introduced two patients with erythematous multiforme, phemphigus, lichenoid reaction and aphthous stomatitis as clinical diagnosis. The lesions were improved by medication.

데이비드 구터슨의 『삼나무에 내리는 눈』: 타자를 대변하는 서사전략 비판

홍성주 한국중앙영어영문학회 2014 영어영문학연구 Vol.56 No.1

David Guterson’s Snow Falling on Cedars describes Japanese immigrant history with the internment and examines the racial bias towards people of Japanese origin after World War Ⅱ. Presenting the irrational trial of Kabuo Miyamoto, Guterson shows the anti-Japanese attitude of the white majority community which originated from the war as well as the prevalent racism. Guterson also devotes himself to explaining the cultural differences between Japanese and white people and promotes mutual understanding. In spite of Guterson’s effort on revealing racial prejudice in the white American society and urging reconciliation between two groups, however, his description serves to prove the limitations when signifying Japanese American’s experience and their voices because Japanese are only represented within the West discourses, only through the white characters. According to Gayatri Chakravorty Spivak, it is unattainable to speak for the subaltern within the West discourses due to an inability to translate the subaltern’s consciousness and experience. Thus, this article explores Guterson’s narrative strategy to represent the other’s experience and criticizes the limitations of the narrative strategy.

한국 주식시장에서 시장 베타와 수익률 간의 관계에 대한 실증 분석

홍성주,임상수 예금보험공사 2019 金融安定硏究 Vol.20 No.2

The purpose of this study is to analyze the relationship between risk and return in the Korean stock market. And it uses market beta proposed by the CAPM(Capital Asset Pricing Model) as measure of risk. After estimating the beta for the stocks and grouping the stocks by the size of the beta, we found that the larger the market beta in the Korean stock market, the lower the return. In order to analyze this more precisely, this study divides the returns into returns that is not related to market excess returns and those that are related to market excess returns. As a result, in the case of a return that is not related to market excess return, it is found that the stocks with a low market beta have a higher return than stocks with a high market beta. In contrast, in the case of returns related to market excess return, the returns on the stocks with low beta are lower than those on the stocks with high beta. In addition, as a result dividing return into a bull market and a bear market, in case of returns that is not related to market excess return, as the beta increased, return declined. On the other hand, return associated with the market excess return increases as the market beta increases in both rising and falling markets. 본 연구는 한국 주식 시장에서 위험과 수익률 간의 관계를 분석하는 것이 목적이다. 또한 본 연구는 위험에 대한 측정 지표로 CAPM에서 제안하고 있는 시장 베타를 활용한다. 베타를 추정한 후 베타의 크기로 그룹화한 결과 한국 주식 시장에서 베타가 클수록 수익률이 하락하는 현상이 발견되었다. 이를 좀 더 정밀하게 분석하기 위해 수익률을 시장초과수익률과 관련 없는 수익률과 시장초과수익률과 관련 있는 수익률로 구분하여 분석했다. 그 결과 시장초과수익률과 관련 없는 수익률의 경우, 낮은 베타를 갖는 종목이 높은 베타를 갖는 종목보다 수익률이 높은 현상이 발견되었다. 반대로 시장초과수익률과 관련 있는 수익률의 경우, 낮은 베타를 갖는 종목이 높은 베타를 갖는 종목보다 수익률이 낮았다. 또한 수익률을 상승장과 하락장으로 구분하여 분석한 결과, 시장초과수익률과 관련 없는 수익률의 경우에는 하락장에서 베타가 증가할수록 수익률은 하락하는 것으로 나타났다. 반면, 시장초과수익률과 관련 있는 수익률은 상승장과 하락장에 관계없이 베타가 증가할수록 수익률은 상승하는 것으로 나타났다.

Background: Core stabilization exercise is an intervention frequently used in the treatment of low back pain. Recently, core stabilization exercises with a sling and vibration stimulation have been attracting attention. Objective: This study was conducted to investigate the effects of a 3-week core stabilization exercise program with a sling and sonic vibrator on pain, muscular endurance, balance ability, and range of motion in patients in their twenties with low back pain. Method: This case series study included two students enrolled at D University. The experiment was performed three times a week for 3 weeks. In the pre-evaluation,contraction time was measured using a pressure biofeedback unit (PBU), and balance, range of motion, and pain were evaluated. The core stabilization exercise program, consisting of warm-up exercises, the main workout, and cooldown exercises, was conducted for 3 weeks. Afterward, a post-exercise evaluation wasperformed using the same method as that in the pre-evaluation. Measurements before and after exercise were analyzed and compared. Results: None of the patients had a significant change in pain. In two patients, contraction time, measured using a PBU, showed a significant difference, confirming the improvement of the muscular endurance of the core muscles. Balance ability, assessed using one-leg stand, and balance ability duration increased after the exercise program. Active range of motion increased in Subject 1 but decreased in Subject 2. Conclusion: This study provides information on core stabilization exercises using a sling and sonic vibrator, which is expected to be useful as an intervention method for muscular endurance and balance ability in patients with low back pain, and can be used as a reference for future studies

시민들의 경찰에 대한 협력의지에 영향을 미치는 요인에 관한 비교연구 : 한국과 우크라이나 간 경찰 신뢰도의 매개효과를 중심으로

홍성주,황의갑,Robert P. Peacock 한국경호경비학회 2021 시큐리티연구 Vol.- No.69

현대 사회의 복잡다기한 치안환경에서 경찰의 목적 달성을 위해 시민들의 협력이 요구됨은 주지의 사실이다. 이에 따라 오늘날 민경 협력치안의 중요성이 강조되고 있으며 학계에서도 시민의 협력의지를 제고하기 위한 연구가 증가하고 있다. 시민들 은 경찰을 신뢰하는 정도에 따라 협력여부를 결정한다고 한다. 이러한 경찰신뢰도는 전통적인 시각의 도구적 모형과 지역사회 구성원간의 유대와 비공식적 통제, 그리고 지역의 도덕수준 등이 신뢰도로 표출된다는 표현적 모형으로 설명된다. 본 연구는 위 두 시각의 요인이 경찰신뢰도의 매개에 의하여 시민의 경찰에 대한 협력의지에 어떠한 차별적인 영향을 주는지 알아보고자 하였다. 이를 위해, 상이한 정치·경제·사회·문화·경찰조직을 가지고 있는 동아시아의 한국과 동유럽의 우크라이 나를 비교·검증 하였다. 그 결과, 양국의 경찰신뢰도와 협력의지에 유의미한 차이는 발견되지 않았다. 또한, 양국 모두 사회적 유대의 인식이 경찰에 대한 협력의지에 대해 일관되게 강한 영향을 주는 것으로 나타났다. 이러한 분석결과를 바탕으로 시 민의 협력의지를 제고하기 위해서 해외 사례 및 정책에 관해 논의하였다 It is a well-known fact that citizens' cooperation with the police is urgently required in the complex and diverse security environment of modern society. For this reason, the importance of voluntary cooperation with the police of citizens to overcome the limitations of the recent response to the crime problem and meet the safety needs of citizens has been emphasized. It is said that citizens decide whether to cooperate or not according to the degree to which they trust the police. The police reliability can be explained by the instrumental model of the traditional perspective and the expressive model that social cohesion, informal social control and the level of morality in the communities are expressed. The purpose of this study was to find out how the factors of the above two models have a discriminatory effect on citizens' willingness to cooperate with the police through the mediation of the confidence of police.In particular, this paper compared and verified Ukraine in Eastern Europe, which have different political, economic, social, cultural, and police organizations from South Korea and South Korea. As a result, there was no difference in the confidence of police and willingness to cooperate between the two countries. This means that in diagnosing citizens' willingness to cooperate with the police, not only official national indicators but also social backgrounds of each country should be considered. In addition, the influence of social cohesion on the willingness to cooperate in the two countries was consistently high. Based on these analysis results, overseas cases and policies were discussed to enhance citizens' willingness to cooperate.
