김명철,이시훈,김종택 한국화학공학회 1989 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.27 No.5

양이온 교환된 faujasite에 대하여 적외선 분광법, X선 회절분석 및 X선 형광분석법을 이용하여 연구하였다. 적외선 흡수띠의 이동이나 Si/Al비 및 결정성의 정도를 고찰하였다. 양이온 교환된 faujasite에 대한 적외선 흡수띠를 분해하먼 T-O(T : Al 또는 Si)의 진동파수가 940-1051㎝^(-1)(띠 A), 1000-1100㎝^(-1)(띠 B), 1097-1190㎝^(-1)(띠 C), 680-730㎝^(-1)(띠 D), 748-780㎝^(-1)(띠 E) 영역에서 나타났다. 띠 A와 E는 각각 Al-O의 비대칭 신축진동(υ_1) 및 대칭 신축진동(υ_2)에 의한 것으로 볼 수 있다. 띠 C와 D는 Si-O의 비대칭 신측진동(υ_3)과 대칭 신축진동(υ_2)에 의한 것으로 각각 보여진다. 띠 B는 Si-O의 비대칭 신축진동(υ_1)과 Al-O의 비대칭 신축진동(υ_3)의 띠가 겹쳐져서 나타난 것으로 볼 수 있다. The cation-exchanged faujasite were characterized and studied by infrared spectrometer, X-ray fluorescence spectrometer and X-ray diffractometer. The shift of i.r. absorption band, Si/Al ratio and degree of crystallinity were studied respectively. The deconvoluted bands of spectra for the cation-exchanged faujasite corresponding T-O vibration frequency appeared at 940-1050 ㎝^(-1) (band A), 1000-1100 ㎝^-1 (band B), 1097-1190 ㎝^-1 (band C), 680-730 ㎝^-1 (band D), and 748-780 ㎝^-1 (band E). The bands A and E were assigned to the asymmetric stretching(υ_1) and symmetric stretching (υ_2) of Al-O respectively. The bands C and D were assigned to the asymmetric stretching (υ_3) and symmetric stretching (υ_2) of Si-O respectively. The band B was assigned to the overlapping of asymmetric stretching (υ_1) of Si-O and asymmetric stretching (υ_3) of Al-O.

이시훈,홍창선 한국방송광고공사 2004 광고연구 Vol.0 No.62

본 연구에서는 위협의 강도와 불안수준, 위협의 발생가능성, 대처반응을 중심으로 위협 소구가 광고효과에 영향을 미치는 구체적인 과정을 살펴보고자 하였다. 구체적으로 위협 소구의 강도(고/저)에 따라 금연캠페인을 주제로 한 두 개의 칼라 인쇄광고물을 제작한 후 사전조사를 통해 실험처치물의 위협의 강도를 구분하였다. 그리고 본 실험은 위협의 강도(고/저)×수용자들의 불안수준(고/저)에 의한 영향을 살펴보기 위해 2×2요인방안으로 설계하였다. 고위협 광고물과 저위협 광고물을 240명의 대학생들에게 보여준 후 위협의 발생가능성, 대처반응, 광고효과를 각각 측정하였다. 연구결과 위협소구의 강도와 불안수준 정도에 따른 위협의 발생가능성에 대한 차이는 나타나지 않았지만, 위협의 발생가능성이 높을수록 문제 회피반응은 낮아지는 것으로 나타났다. 또 문제회피반응은 광고태도, 금연태도와 같은 태도차원의 광고효과에 영향을 미치는 것으로 나타났다. This study aims to examine detailed process that fear appeal has an influence on the advertisement effects focusing on the strength of fear, the level of anxiety, the occurrence probability of fear and coping response. That is, it aims to contribute to establishing proper fear effect strategy by examining the effects of fear appeal through detailed cause and effect process. As a result of verifying the hypothesiss, the follows found; Firstly it was found that the difference in the probability of occurrence according to the level of anxiety and the strength of fear appeal was insignificant. Secondly it was found that the problem solving response did not become higher as the probability of occurrence becomes higher, but problem avoiding response did not become lower as the probability of occurrence becomes higher, and this hypothesis was partially adopted. Lastly the problem solving response did not affect the advertisement effect. However, problem avoiding response was found to affect the advertisement effect of attitude such as advertisement attitude and antismoking attitude.

양방향 TV 광고의 효과에 관한 실험연구 : 상호작용 행동의 영향변인과 결과변인을 중심으로

이시훈,탁진영 한국방송광고공사 2006 광고연구 Vol.0 No.71

디지털 방송의 도입으로 여유 주파수를 이용한 데이터 방송이 도입 되었고, 광고에 있어서는 양방향 TV 광고가 가능하게 되었다. 이러한 양방향 TV 광고에 대한 학문적 논의가 활발하였지만 주로 정책제도 연구와 의견조사 연구들의 주류였다. 이러한 점에서 본 연구는 정교화 가능성 모델, 플로우 이론, 역할수행 이론을 토대로, 양방향 TV 광고의 가장 큰 특징인 상호작용 행동을 시청자들의 TV 시청과 유사한 환경에서 실제 측정하여 상호작용 행동의 영향변인과 결과변인과의 관계를 규명하고자 하였다. 연구결과, 상호작용 행동에 영향을 미치는 선행변인중 제품관여도는 통계적으로 유의한 영향을 미치지 못하는 것으로 나타난 반면에 인지욕구와 통제성 인식은 정적인 영향을 미치는 것으로 나타났다. 또 상호작용 행동은 광고회상, 광고태도, 브랜드태도, 구매의도 등 전통적인 광고효과 측정의 종속변인들 모두에 통계적으로 유의하게 정적인 영향을 미치는 것으로 나타났다. 이러한 결과는 양방향 TV 광고에서 상호작용 행동은 단순히 회원가입이나 쿠폰요청, 구매 등과 같은 행동 차원의 효과 이전에 인지적 그리고 평가적 차원에서도 큰 효과를 발휘함을 의미하는 것이다. As the Korean broadcasting system introduce digital broadcasting system relying on data broadcasting using surplus broadcasting frequencies, we can experience the interactive TV advertising. Although many academic interests focused upon interactive TV advertising, most studies concerned only with policy issues and expert opinion survey matters. For this reason, this study tried to reveal the relationship between influencing variables and consequent variables of the interactivity based upon Elaboration Likelihood Model, Flow Model, and Role Playing Theory with the measurement of the interactivity on real TV viewing situation. As a result, the need for cognition and recognition of control, unlike the product involvement, showed statistically significant influences on the interactivity. The results also revealed that the interactivity proved to be the significant predicting variable of Aad, Ab, Ad recall, and the intention to buy. These results meant that the interactivity showed the influences not only on the cognitive and affective levels of interactive TV advertising, but also on the behavioral levels of interactive TV advertising including membership subscription, coupon requests, and purchase.

이상훈,윤하나,심봉석,이시내 이화여자대학교 의과대학 2003 EMJ (Ewha medical journal) Vol.26 No.2

Purpose : Ureteral stent is commonly used after ureterscopic stone removal(URS). However, there is no definitive clinical criteria in inserting the ureteral stent after URS. Patients often complain of bladder irritative symptoms, hematuria. flank pain and additive endoscopic prodedure is neces-sary to remove the ureteral stent. Therefore, we studied the clinical epicacy of selective ureteral stenting only when it is required. Materials and Methods : Of the patients who was taken URS, the following patients were exclu-ded from stent insertion ; 1) Patients who have mild hydronephrosis or symptoms less than 1week. 2) Patients who were able to insert the ureteroscope through the ureteral orifice without difficulty. 3) Patients who hardly have ureteral mucosal damage seen through the ureteroscopic field after the removal of ureteral stone. 4) Patients who did not need the additional lithoclast during the remo-val of ureteral stone. Other than the above patients and those with stones above the mid-ureter, a 6Fr. ureteral stent was inserted and kept for 3weeks. There were 29 unstented patients and 38 stented patients. Results : The average age of the non-stenting and stenting group were 37.5years old and 39.7years old and the average stone size were 0.68cm and 0.80cm. The average operation time was 3 minutes in the non-stenting and 8minutes(including ureteral stent insertion time) in the stenting group. Hos-pital stay was 3days in both groups. Intermittent gross hematuria and irritative symptoms of the bladder was shown for 3weeks after operation in most of the patients(32cases, 84.2%) of the sten-ting group while those in the unstenting group, the symptoms were relieved after2days after operation. Although mild flank pain was shown in few patients(4cases, 13.8%) of the non-stenting group, severe pain requiring intravenous analgesics was not seen in both groups. There were no specific findings in the intravenous urography which was done at 6weeks after operation, and no hematuria and pyuria was found in both groups. Conclusion : The selective placement of ureteral stent following the ureteroscopic removal of stone did not bring specfic complications. We believe that ureteral stent insertion will minimize the inconvenience especially in patients who need to return to their everyday living immediately after operation. Thus ureteral stent insertion should be used in limited situations. 요관경하배석술 후 많은 경우에 있어서 요관부목을 유치하고 잇지만 선별적으로 판단하여 설치할 경우 특별한 문제점이 없었으며, 수술 수 바로 일상생활에 복귀하여야 하는 환자들의 불편함을 최소화할 수 잇을 것으로 생각되며, 요관부목 설치는 제한적인 상황하에서 시행되어야 할 것으로 사료된다.

이시훈,송기인 한국방송광고공사 2008 광고연구 Vol.0 No.78

본 연구는 양방향 광고를 통한 구매행동의 구매 후 영향과 향후 구매의사에 영향을 미치는 영향을 미디어 대체가 설과 확산이론을 토대로 조사하고자 하였다. 실제 T-commerce를 경험한 소비자 200명을 대상으로 전화조사를 실시한 결과, T-commerce 경험 후에는 TV홈쇼핑과 인터넷 쇼핑 구매건수가 감소하는 것으로 나타났다. Tcommerce 이용 만족도와 데이터 방송 이용 시간이 향후 T-commerce를 통한 구매의사에 정적인 영향을 미치는 것으로 나타났다. T-commerce에 대한 평가(긍정적, 부정적 평가), TV 시청시간, 인구통계적 특성은 향후 Tcommerce를 통한 구매의사에 미치는 영향이 발견되지 않았다. The purpose of this study is to research the effects of decision making on buying and buying behavior after buying on the basis of media substitution hypothesis and diffusion theory. The method of research was telephone survey and 200 consumers who have experienced Tcommerce was surveyed. In a result of this research, the number of buying in TV home shopping and internet shopping after experiencing T-commerce was declined. The Tcommerce satisfaction and the time using data broadcasting was in positive relation with decision making of buying with T-commerce. The evaluation of T-commerce, the time viewing TV, and the demographic factors were not related with decision making of buying with future’s T-commerce.

이기현,박시훈,신길자,이우형 梨花女子大學校 醫科大學 醫科學硏究所 1995 EMJ (Ewha medical journal) Vol.18 No.4

본 저자들은 고혈압이나 지지조직의 병변, 선천성 심장질환등의 유발 인자 없이 지내던 환자가 갑작스런 신체적긴장으로 흉통이 유발된 후 진행성 애성이 발생하여 애성의 원인 진단 및 치료를 목적으로 내원한 후 대동맥 박리를 진단받은 사례를 경험하였기에 이에 보고하는 바이다 Aortic dissection is caused by a circumferential or transverse tear of the intima by a discrepancy between the strength of the aortic wall and the intraluminal pressure. Arterial hypertension seems clearly to be a factor in the genesis of aortic dissection. An elevated blood pressure or evidence of its existence can be found in 70-80 percent of patients. Other factors predisposing to aortic dissection are congenital disorder of connective tissue, vasculitis, etc. But trauma or physical strain is unusual cause of classic dissection. Diagnosis is confirmed by computed tomography, aortography or echocardiography. A 62-year-old man without a history of hypertension, emphysema or congestive heart failure visited our hospital because of hoarseness which developed suddenly during the physical strain. A contrast material-enhanced computed tomographic (CT) scan was performed at an other hospital due to hoarseness, mild fever and general weakness. Then he visited to our ENT department and performed laryngeal CT due to hoarseness. The CT shows somewhat mass-like soft tissue, so he was transferred to our internal medical department. The chest CT scan and simple chest PA was done and we found a dissecting aneurysm. This case developed by Physical strain and diagnosed by hoarseness is unusual and rare.
