Purpose: This study was undertaken to evaluate the prognostic factors for patients suffering with alcoholic ketoacidosis. Methods: We retrospectively evaluated and categorized 55 alcoholic ketoacidosis patients into two groups: the survivors (group 1) and non-survivors (group 2). We compared the general characteristics and the laboratory results, including the arterial blood gas analysis (ABGA) and the complications of the two groups, and we assessed the severity of the between the two groups by using the Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score and the Simplified Acute Physiology Score (SAPS). Results: There were 50 male patients (90%) and 5 female patients (10%). On laboratory testing, the levels of arterial HCO₃ -, total protein, albumin and serum glucose were significantly lower in group 2 than that in group 1. The levels of total bilirubin and BUN (blood urea nitrogen), the PT (prothrombin time) and the aPTT (activated partial thromboplastin time) were significantly higher in group 2 than that in group 1. Serial ABGA follow-up showed that unimproved ABGA results meant a poor prognosis. The SAPS was significantly higher for group 2 than that for group 1 (p<0.001) but the APACHE Ⅱ was not significantly different. The incidence of hepatic encephalopathy, hepatic failure and acute respiratory distress syndrome (ARDS) were higher in group 2 than that in group 1. The total bilirubin, arterial HCO₃ - and albumin were found to be significant prognostic factors by logistic regression analysis. Conclusion: The poor prognostic factors for alcoholic ketoacidosis were low levels of arterial HCO₃ -, impaired hepatic function, the incidence of ARDS and unimproved ABGA results.

이중목적어구문의 구조와 LF 복사본 삭제 제약

이제원 한국중앙영어영문학회 2014 영어영문학연구 Vol.56 No.1

The aim of this study is to represent the structure of English Double Object Constructions. To meet the goal, however, it is attempted to avoid using ad-hoc DOC-specific grammatical apparatus or functional category. Once it is permitted, we encounter another problem why we are not able to meet a verb construction which has three or more nominals complements. To meet the constraint, IO is forced to bear two theta roles in the course of its DOC derivation. However, once an argument, IO in DOC, is allowed to have more than one theta-role, it can be explained the peculiarity DOC has shown compared to other alternating 3-place verb constructions just only with grammatical apparatus and grammatical categories widely accepted in the field. Also the property of IO which has been proposed in the filed can help explain why IO has had shown different syntactic properties compared to other nominal complements. Furthermore, from this property it can be derived a constraint on deletion of copies at LF. However, it has to be clarified in further studies that what happens when an argument gets more than one theta-role between the theta roles in the same argument. It has stated that IO is able to bear creator role as well as possessor role depending on the nature of DO.

A reusable and efficient photo-catalyst based on halloysites (HNTs) and La3+ ion-doped TiO2nanoparticles was prepared using a sol-gel process and a sonochemical method for decomposingorganic dyes. As a support, the HNTs increased the adsorption efficiency of substrates, improving thephotocatalytic activity of TiO2 nanoparticles by3 times. The La3+ ion doping of TiO2 decreased thebandgap from 3.25 eV to 3.01 eV, expanding the spectral response to the visible region and enhancing thephotocatalytic activity under the sunlight by 1.5 times. Through the integration of the halloysite supportand the La3+ ion doping of TiO2, the synergistic enhancement of photocatalytic activity was observed andsystematically investigated using XRD, Raman spectroscopy, FT-IR, FE-SEM, EDX-TEM, and zeta potential. In this research, we used Rhodamine B molecules as a model pollutant. During the decomposing process,the HNTs enhanced the local dye concentration nearby the photo-catalyst through the electrostaticinteraction, thereby boosting the photocatalytic activity by3 times. Additionally, the catalyst can beseparated by simple centrifugation and reused at leastfive recycles without any activity decrease. Thehalloysite support, the La3+ ion doping of TiO2 and their simple synthesis approach could provide apractical tool for environmental purification in wastewater using sunlight.

메타버스 상호작용성이 경험가치와 지속이용의도에 미치는 영향

이제원 한국유통경영학회 2022 유통경영학회지 Vol.25 No.4

Purpose: Contrary to the growth of Metaverse expanding through the generation MZ, research on the continuous use intention of consumer behavior is limited. This study aims to reveal the relation between the impact and the continuous use intention the interactivities among humans in the Metaverse has in terms of a consumer experiential value(economic, service, and educational). Through this study, we analyze consumer behavior within Metaverse and expand the theory. Research design, data, and methodology: This study had conducted an exploratory factor analysis and confirmatory factor analysis to analyze the reliability and validity of the measurement items through SPSS21.0 and AMOS20.0. For verifying the research hypothesis, the goodness of fit test and hypothesis of the research model were verified using AMOS20.0 and presented the results. Results: The result showed that the interaction within the Metaverse has a positive(+) impact in terms of an experience value and also offered the extent of its influence through economic value and educational value. The experience value with the highest positive(+) impact on the continuous use intention of Metaverse was identified as an economic value. At the same time, the service value also significantly affected it. However, the educational value does not influence the intention to continuous using the Metaverse, reconfirming previous research findings that there is a limit to expect on the educational value in the Metaverse. Finally, the study also revealed that the interactivity within the metaverse affects the continuous use intention. Implications: As a result, confirmed the influence and relationship between the interactivity and experience value of consumers who are participating in the newly introduced environment, or the Metaverse, and suggested ways to enhance the economic value and service value in order to amplify the continuous use intention the Metaverse.

고려 江都 長峯宮의 위치 비정 - 발굴 사례를 중심으로 -

이제원 숭실사학회 2021 숭실사학 Vol.- No.47

강도(江都)는 1232년부터 1270년까지 고려의 수도였지만 발굴조사를 통해 그 성격이 명확히 강도시대의 건물이라고 밝혀진 건축 유적은 얼마 없다. 하지만 발견된 몇몇 유적중에서 인화-강화 도로구간 문화유적 M지점에서 발굴된 고려시대 가 건물지가 장봉궁일 가능성이 제기되었다. 장봉궁(長峯宮)은 강도시기의 별궁 중 하나이며, 장봉신궁(長峯新宮)은 장봉궁과 같은 장소 에 세워진 궁이었다. 두 별궁의 명칭이 다르게 기록된 이유는 건물의 개축으로 장봉신궁이 새로 지 은 건물이었기 때문이다. 장봉궁으로 비정되는 건물지가 위치한 갑곶(甲串) 일대는 강도 성곽 체 계에서 몽골군을 방어하는데 중요한 전략 거점이었다. 육지에서 강화도로 들어가는 나루는 제포 와 갑곶 두 곳이었다. 몽골 사신과 같은 귀한 손님들은 주로 제포를 이용하였다. 그러나 대부분 의 사람들이 이용하고, 전국에서 올라오는 생산품이 들어오는 중요한 곳은 갑곶이었다. 또한 강 도 도성 내의 중요 거점을 모두 조망할 수 있는 곳에 위치한 가 건물지는 사찰이나 귀족의 사저 보다는 왕의 별궁일 가능성이 높다. 개경의 육요(六窯)와 관련된 <월개(月蓋)명 인장와>가 가 건물지와 같은 유적의 다 건물지에서 출토된 것으로 보아 가 건물지는 왕실과 연관된 건물지일 가능성이 높다. 가 건물지에서 12세기 후반에서 14세기 전반까지의 유물이 출토된 점은 왕의 장봉궁 행차 기록을 통해 본 건물지의 연대 와도 일치하여 그 연관성을 높여준다. 또한 ‘장봉’과 관련된 지명을 검토한 결과, ‘장봉’과 ‘동 산’, ‘장령’, ‘만수산’이 모두 오늘날 갑곶의 ‘당산’과 같은 곳을 지칭하는 것을 확인하였다. 비록 장봉궁을 직접적으로 지칭하는 유물과 기록은 확인되지 않았지만 건물지가 강도의 중요 한 곳에 위치한 점, 건물지의 초축 개축 폐기 양상, 그리고 역사 사료를 검토한 결과 장봉궁일 가능성이 높다. Gangdo capital was the captial city of the Goryo Dynasty bewteen 1232 and 1270, but only a few architectural remains unearthed by the excavations were specifically identified as being built during that period. But, recently, the possibility was raised that, among those historical remains, the makeshfit building site found in M point on the road between Gang’hwa and Inhwa might be Jang-bong P alace. Jang-bong Palace was built as one of the attached palace buildings of Gangdo capital era, and, some time later, this structure was remodeled and called Jang-bong new Palace. This is why the same building had two different names. Gapgot area where Jang-bong Palace was assumed to be located was a strategically important point in defending Mongol army. Gapgot and Jepo was the only two docks connecting Gang’hwa Island to the mainland. While important guests, such as foreign envoys from the Mongol Empire, used a boat in Jepo port to visit Gang’hwa Island, most oridnary people as well as products from all over the country traveled and transported to Gang’hwa Island via Gapgot port. The fact that all imporant locations in Gangdo capital fortress could be observed from the makeshift building also increases the likelihood that it could be the king’s attached building rather than a temple or a private residence of the aristocratic class. In addition, there are two more evidences that supports the argument that the builing could belong to the royal family. To begin with, given that <月蓋 Stamped roof tiles>, which was closely associated with Six kiln in Gaegyeong, was found in another makeshift palace built in the same historic site, this building is more likely to be related to the royal family. On top of that, the period, roughly between late 12th century and eary 14th century, when the historic remains was assumed to be built, exactly corresponds with the time when the king was recorded to have marched around the Jang-bong Palace. Also, the research on the origin of the names of the places associated with ‘Jang-bong’ indicated that ‘Jang-bong’, ‘Dong-san’, ‘Jangryeong’, and ‘Mansu-san’ all r efered to the same place as ‘Dang-san’ toda y. Although no historical relics and artifacts, and written documents confirmed it is Jang-bong Palace, there are three possible reasons that strongly support that it could be Jang-bong Palace; the building was located in a crucual site in Gangdo capital, how the building was first built, remodeled, and demolished, and finally, a thorough analysis of historical records.

온/오프라인 유통경로 서비스품질 평가요인이 만족과 재이용의도에 미치는 영향에 관한 연구

이제원,이주호,오태현 한국상업교육학회 2008 상업교육연구 Vol.22 No.-

본 연구의 목적은 실증자료 분석을 통하여 온/오프라인 유통경로 구매의존도에 따라 유통경로 서비스품질에 대한 평가가 유통경로상의 특성을 비교하여 평가하는 것인지, 온라인 상의 경쟁업체간 쇼핑몰이나 오프라인의 경쟁업체 점포 간의 비교에 의해 평가되는지, 그리고 어떠한 유의적 차이가 있는지에 대한 가설검증과 이러한 온/오프라인 서비스 품질에 대한 상대적 비교평가 정도가 유통서비스 만족과 재이용의도에 어떤 영향을 주는 가에 대한 연구가설을 검증하는데 있다. 가설검증 결과, 온라인 구매의존도가 높은 이용자들이 온라인의 서비스품질과 오프라인 서비스 품질의 비교정도에 있어서 오프라인에 대한 구매의존도가 높은 이용자 보다 유의성이 높게 나타났으며, 온라인상의 경쟁 쇼핑몰 서로 간의 서비스품질 비교정도에 있어서는 온라인 구매의존도가 높은 이용자들의 경우 유의성이 높게 나타났지만 오프라인 구매의존도가 높은 이용자들의 경우는 유의성이 없는 것으로 나타났다. 또한 전자의 경우와 후자의 경우 중 유통서비스 만족과 재이용의도와의 관계에 있어서는 후자의 경우는 유통서비스 만족과 재이용의도에는 유의성이 높게 나타난 반면 전자의 경우는 유의성이 없는 것으로 나타났다. 따라서 본 연구결과의 시사점은 향후 온/오프라인 유통경로를 운영하는 기업들의 마케터들은 소비자들의 온/오프라인 유통경로 선택속성 파악과 이에 대한 서비스개선노력에 있어서 온/오프라인 유통채널이 가지고 있는 고유의 차이점에 대하여 주안점을 두고 차별화를 통한 경쟁력 제고에 주력하기 보다는 온라인상(웹망)에서의 경쟁업체 쇼핑몰 간 유통경로 선택속성들의 서비스 차별화를 통한 경쟁력 제고에 지속적인 노력을 기울여야 될 것으로 생각된다.
