유상훈,김성안,홍용의,문성웅 한국화재감식학회 2013 한국화재감식학회 학회지 Vol.4 No.1

The Steiner Tunnel Test is a widely used method of testing building interior wall and ceiling finishes for their ability to support and propagate fire, and for their tendency to emit smoke. The test was developed in 1944 by Al Steiner of Underwriters Laboratories, and has been incorporated as a reference into North American standards for materials testing as tests ASTM E84, NFPA 262, NFPA 255, UL 723 and ULC S102. These standards govern the regulation and selection of materials for interior building construction throughout North America. This research compares ASTM E84 with NFPA 262 and can help to design the Steiner Tunnel Furnace. In ASTM E 84, test specimens are Building materials, test time is 10 minutes, supporter is steel mesh, exhaust duct type is U-shaped, measurement is hot wire or pitot tube and test results are Light Absorption, Flame Spread Index, Smoke Developed Index. In NFPA 262, test specimens are Wires and cables, test time is 20 minutes, supporter is ladder, exhaust duct type is straight, measurement is Bi-Directional Probe and test results are Optical density of smoke (peak optical density, average optical density), Linear duct velocity, Smoke Release Rate, Heat Release Rate, Flame travel distance/time.

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.

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 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.

Investigation of Success Factors in Global Cafe Market

유상훈,이상협 경성대학교 산업개발연구소 2023 산업혁신연구 Vol.39 No.1

This study investigates the factors of satisfaction with cafes frequently visited by consumers. Meeting the needs of consumers who visit cafes often plays a vital role in continuously and stably operating cafes. Making consumers visit the same cafes regularly is necessary for running the cafe because having many regular customers is beneficial to making a significant profit. A total of 14 interviewees participated in the interview of this study and expressed the following opinions. Customers who visit the cafe are essential in recognizing the location of the cafe and the type and taste of food and beverage. In other words, it was found that consumers prefer cafes located at a convenient distance to visit. In addition, regular customers have been found to select the high-quality taste of food and beverage served at cafes and various menus because they quickly get tired of the same menu and often visit the cafes. Factors such as the unusual interior of cafes and large parking lots have also been shown to be necessary to customers, so differentiated interiors must be considered to satisfy customers' needs. It was also found that customers want to visit cafes to relax, read, and enjoy hobbies. Therefore, it is more efficient for cafe owners and consumers to create a cafe culture together because they can create a style of cafe that consumers prefer.

Effects of Extraction Methods on In Vitro Biological Capacities and Rheological Properties of Polysaccharides from Red Pepper Stems

유상훈,장윤혁 한국식품영양과학회 2017 Preventive Nutrition and Food Science Vol.22 No.3

The purposes of this study were to produce polysaccharides from red pepper stems using different extraction methods and evaluate their chemical composition, in vitro biological capacities, and rheological properties. Two polysaccharides were extracted from red pepper stems using an autoclave and alkali treatments, and the extracts were named PAU and PAL, respectively. The contents of total phenolics and flavonoids were significantly higher in PAU than those in PAL. PAU exhibited greater scavenging activities on 2,2-diphenyl-1-picrylhydrazyl radicals, 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radicals, superoxide radicals, and nitrite compared to PAL, suggesting that PAU served as better antioxidants. Similarly, in vitro inhibitory abilities against carbohydrate hydrolyzing enzymes of PAU were higher than those of PAL. Steady shear rheological analysis demonstrated that PAU showed higher psuedoplastic shear-thinning behavior compared to PAL. Based on the results from dynamic shear rheological properties, it was found that both samples had predominantly viscous behavior rather than elastic behavior.

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.
