이 연구는 Morphine을 이용한 저작근통증의 조절 효과를 확인하기 위해서 시행되었으며, 경희대학교 치과대학병원 구강내과에 내원한 환자 중 RDC/TMD로 진단된 지원자를 saline 주사군, lidocaine 주사군, morphine 주사군 각각 10명씩 배정하였다. 통증부위에 주사 전, 주사 후 10분, 30분, 60분에 각각 주관적인 통증 평가인 시각유추척도검사, 맥길통증설문지검사 그리고 통증부위표시검사와 객관적인 통증 평가인 압력통증역치검사와 압력통증한계검사를 실시하였다. 검사 후 평가된 자료를 통계 처리하여 다음과 같은 결과를 얻었다. 1. 주관적인 통증 평가와 객관적인 통증 평가 모두 집단 내 효과가 있었다. (p<0.001) 2. 주관적인 통증 평가인 통증부위표시검사(p<0.001)에서 집단 간 효과가 있었다. 3. 객관적인 통증 평가인 압력통증역치검사(p=0.025)에서 집단 간 효과가 있었다. 4. 주관적인 통증 평가인 통증부위표시검사는 morphine 주사군(p=0.001)이 saline 주사군에 비해서 효과가 있었다. 이상의 연구결과로 저작근에 통증이 있는 환자에게 morphine 주사 시 60분 이내에는 주관적인 평가에서 통증 조절 효과가 있었으며, 향후 시간 연장에 따른 지속적인 추가 연구가 필요 할 것으로 생각된다. This study was designed to evaluate the pain control effect by morphine injection to masticatory muscle pain patients. Patients with masticatory muscle pain visited the Department of Oral Medicine, Kyung Hee University Dental Hospital were recruited to this study and diagnosed by RDC/TMD. Experimental group were divided into three group; saline injection group(n=10), lidocaine injection group(n=10) and morphine injection group(n=10). Evaluation list was the subjective pain evaluation(visual analogue scale, Mc Gill pain questionnaire, pain drawing) and the objective pain evaluation(pressure pain threshold, pressure pain tolerance) and evaluation time was injection before, after 10min, 30min, 60min and then it was analyzed statistically. The results were as follows : 1. The subjective pain evaluation and the objective pain evaluation were significantly different statistically in within subject effects(p<0.001). 2. The subjective pain drawing evaluation(p<0.001) were significantly different statistically in between subject effects. 3. The objective pressure pain threshold evaluation(p=0.025) were significantly different statistically in between subject effects. 4. The morphine injection group(p=0.001) were more significantly different than the saline injection group statistically in the subject pain drawing evaluation. Therefore, it was considered that the morphine injection was effective to pain control for masticatory muscle pain patients within 60 minute.

유상훈,이상협 경성대학교 산업개발연구소 2022 산업혁신연구 Vol.38 No.3

The purpose of this study was to analyze the opportunities for tourists to participate in domestic and foreign food festivals. In addition, we explored whether tourists who have participated in the food festival are willing to recommend it to people around them or visit the food festival together in the future. This study used interview techniques during qualitative research and a total of 12 tourists participated in this study. We found that tourists wanted to eat various and distinctive foods through food festivals. In addition, we found that tourists were preciously aware of obtaining information and knowledge about local culture and ingredients learned through food festivals. In addition, tourists who participated in overseas food festivals were found to be highly satisfied because they not only experience food festivals but also partake in visiting tourist attractions. The more famous tourist destinations that host food festivals become, the more tourists intend to visit, which are contributors to the development of the local economy. Tourists participating in the food festival have a high rate of revisiting because they can eat freshly prepared food and purchase regional food or ingredients during the festival. In addition, tourists prefer to experience the local food culture and various hands-on tourism programs through food festivals. In addition, tourists visiting food festivals such as family and friends were found to feel positive emotions while experiencing these hands-on tourism programs.

중력자료를 이용한 북극 스발바드 군도의 지각구조연구

유상훈,이성숙,민경덕,Yu, Sang-Hoon,Yi, Song-Suk,Min, Kyung-Duck 한국석유지질학회 2007 한국석유지질학회지 Vol.13 No.1

ArcGP 중력자료를 이용하여 다산과학기지가 위치한 북극 스발바드 군도의 중력특성을 파악하였다. 지형자료와 유사한 형태로 분포하는 free-air 중력이상에서 보이던 대륙 연변부의 가장자리 효과는 부게보정 후 보이지 않고, 육상지역의 CTOPO30 지형자료를 이용한 지형보정을 거친 완전 부게 중력이상에서 육상지역에서 해양지역으로 갈수록 중력이상이 증가하는 즉, 모호면의 상승과 관련이 깊은 특성이 관찰된다. 파워스펙트럼 분석을 통해 결정된 절단파수를 이용할 필터링 후 계산된 고주파 영역의 잔여이상에서 육상지역의 단층대를 따라 발달하는 특징적인 고이상대와 두꺼운 퇴적층에서 기인한 저이상대가 나타나며 해양지역 대륙사면의 최하부에서 기반 함몰 내지는 기반암 상부의 두꺼운 퇴적층과 관련이 있는 저이상대가 발달하고 있다. 역산 모델링을 통해 저주파 영역 성분에서 계산된 모호면의 기복은 스발바드 군도에서 유라시안 판 경계인 Knipovich ridge쪽으로 갈수록 상승하는 즉, 대륙주변부에서의 전형적인 특성을 보여준다. Gravity characteristics are investigated in the vicinity of the DASAN scientific station, located at the Svalbard Archipelago, the Arctic using ArcGP data. Boundary effects of free-air gravity anomalies, which appeared generally at the continental margin, are erased after Bouguer correction was applied. Complete Bouguer anomalies produced after terrain correction by GrOPO30 show that gravity anomalies increase from continent to marine. This phenomena seem to be related to the rise of Moho discontinuity. The cut-off frequency of 0.16 was decided after power spectrum analysis and the gravity anomalies were divided into two parts. Residual anomalies in high frequency part show that characteristics of high values along the faults and of low values related to thick sediments in the continent. Characteristic is low values from basement subsidence of continental slope or thick sediments in the marine. The undulation of Moho discontinuity from 3-D inversion modeling show typical characteristics of continental margin that become higher from Svalbard archipelago to Knipovich ridge bordering Eurasian plate.

유상훈,이재하,유광하,정기석,이진국 대한결핵및호흡기학회 2018 Tuberculosis and Respiratory Diseases Vol.81 No.3

Background: Chronic bronchitis (CB) is an important phenotype in chronic obstructive pulmonary disease (COPD). The purpose of this study is to evaluate different pattern of COPD assessment test (CAT) score between CB and non-CB patients. Methods: Patients were recruited from 45 centers in Korea, as part of the Korean COPD Subgroup Study cohort. CB was defined when sputum continued for at least 3 months. Results: Total 958 patients with COPD were eligible for analysis. Among enrolled patients, 328 (34.2%) were compatible with CB. The CAT score was significantly higher in patients with CB than non-CB, and each component of CAT score showed a similar result. CB was significantly associated with CAT score when adjusted with age, sex, modified Medical Research Council, and post-bronchodilator forced expiratory volume in 1 second. Each component of CAT score between patients with CB and non-CB showed different pattern according to Global Initiative for Chronic Obstructive Lung Disease grade. Conclusion: CAT score is significantly higher in patients with CB than non-CB. Each component of CAT score was significantly different between two groups.

중력자료를 이용한 한반도 중부 대륙-해양 지역의 지각구조 연구

유상훈,민경덕,박찬홍,원중선 대한자원환경지질학회 2002 자원환경지질 Vol.35 No.5

자료의 부족 및 육.해양을 동시에 감안해야 하는 상황으로 인하여 아직까지 한반도 중부 대륙에서 해양지역으로 이어지는 대륙연변부에서의 심부지각구조에 관한 심층적인 지구물리학적 연구는 이루어지지 못하였다. 본 연구에서는 중력자료를 이용하여 대륙과 해양을 잇는 대륙연변부 북위37$^{\circ}$~38$^{\circ}$, 동경128$^{\circ}$~132$^{\circ}$지역에 대한 심부지각구조를 해석하였다. WCA보정을 이용하여 해상지역의 선상중력자료에 나타나는 탐사측선상의 잡음으로 판단되는 고주파성분을 제거하고, 보정된 해상지역의 free-air 중력이상을 동일한 고도 기준면을 갖는 육상지역의 부게 중력이상과 결합하였다. 연구지역의 중력이상을 4개 지역으로 나누고, 각각의 지역에 대한 파워스펙트림 분석에 의해 산출한 모호면으로 판단되는 밀도 경계면은 한반도 내륙 부에서 대륙주변부를 지나 동해 울릉분지 쪽으로 갈수록 심도가 점점 얕아지는 양상을 보인다. 파워스펙트럼 결과에 의해 기초 모델로 설정하고 모델링을 실시한 결과, 모호면의 심도는 한반도 내륙지역에서는 약 33~35 km로 나타나고, 대륙주변부에서의 모호면의 심도는 18~28 km로서 한반도 내륙지역에 비해 얕아진다. 이와 같은 구조적 특성은 울릉분지의 주변부를 따라 나타나고 있는 중력변화에서도 잘 나타나고 있다. 울릉도 남쪽 해역에서의 모호면은 약 16~17 km로 대륙 쪽의 모호면 깊이보다 훨씬 얕다. 이와 같이 중력자료로부터 구한 지각모델의 결과는 인근 지역에서 이루어진 탄성파탐사를 통한 지각모델링 결과와 매우 유사하게 나타났다. There have been few geophysical studies on the crustal structure of the continent-ocean zone around the middle eastern part of Korean peninsula, because of the lack of database in both land and ocean. The area for the study on the internal crustal structure using gravity data is bounded by the latitude of 37$^{\circ}$-38"N and longitude of 128$^{\circ}$-132$^{\circ}$E. WCA correction is applied to shipborne gravity data to integrate with gravity anomalies obtained on land. The high frequency components of the shipborne gravity data which are considered as the noise on survey track are effectively removed by means of correlating with satellite gravity data. The corrected shipborne free-air gravity anomaly is integrated with the Bouguer gravity anomaly on land under the same condition. The integrated gravity anomaly is divided into four areas for power spectrum analysis. The depths of Moho discontinuity increases gradually from inland to Ulleung basin. As the result of modeling based on power spectrum analysis, Moho discontinuity depth is about 33-35 km in the continental zone of Korea and 18-28 km at the continental margin. Such structural character is well elucidated in changing gravity data around Ulleung basin. The depths of Moho discontinuity in the southern ocean of Ulleung-island is 16--17 km, which is much lower than in the land. The result of crustal structure modeling in this study is similar to that computed by prior seismic exploration around this area.
