정보제시유형에 의한 개인투자자들의 주식투자의도

이재은(Lee, Jae-eun) 한국상품학회 2019 商品學硏究 Vol.37 No.3

본 연구는 정보제시유형에 따라 나타나는 개인투자자들의 반응을 살펴보기 위해 개인투자자들의 투자성향과 주식투자의도와의 관계를 검증하였다. 개인투자 자유형은 Goldberg and Nitzsch (2001)의 의해 논의되어지고 이재은 (2015)에 의해 본능적/감정적/이성적 투자자집단으로 분류되어 사용되었던 변수를 이용하였 다. 연구결과 ‘메시지정보제시형태에 따라 개인투자자들의 주식투자의도는 다르게 나타날 것이다’라는 가설은 모두 긍정적인 것으로 나타났다(F=5.12, p= .00, F=20.63, p= .00). 그러나 개인투자자유형과 정보제시유형 간의 상호작용은 발생되지 않았다(F= .63, p= .54). 이러한 결과는 소비를 목적으로 하는 소비재와는 달리 재무적 위험을 수반하는 주식은 이익을 통해 부를 증가시키기 위한 수단으로 위험부담을 줄여 손실을 최소화하는데 목적을 두기 때문인 것으로 해석된다. 또한 주식투자의도에 관한 개인투자자들의 유형별 차이를 살펴보면, 감정적 투자자들은 부정적(손실) 정보보다는 긍정적(이익) 정보에 더 긍정적인 것으로 나타났다(M= .05<M= .43). 본능적 투자자는 부정적(손실) 정보보다 긍정적(이익) 정보에 매우 민감하게 반응(M=- .37< .34)하였으며, 이성적 투자자들 또한 부정적(손 실) 정보보다 긍정적(이익) 정보에 긍정적인 반응을 나타냈으나(M=- .49< .04) 이익에 대한 기대감을 크게 나타내지는 않았다. 투자의도에 관한 투자자유형간의 차이는 전반적으로 유의미하였으나 큰 차이를 보이지 않은 것으로 연구결과 나타났다. 본 연구는 개인투자자들의 인지 행위적 측면을 실증적으로 검증해 보았다는 점에서 연구의 의의가 있다. This article verified the differences in the relationship between investment propensity and stock investment intention of private investors based on stock items according to the method of information presentation. Private investor types were divided into gut, emotional and rational investor groups, as discussed by Goldberg and Nitzsch (2001) and classified by Jae-eun Lee (2015). The results positively supported the hypothesis that ‘Stock investment intention of private investors varies with the method of message information presentation’ (F=5.12, p= .00, F=20.63, p= .00). However, there was no interaction between the private investor type and the method of information presentation (F= .63, p= .54). This is because stocks are financial instruments that accompany financial risks and the purpose is to minimize loss by reducing risk factors, unlike ordinary consumption goods that are intended to be consumed. Looking at the average difference in stock investment intention among private investor types, emotional investors were found to be more positive toward positive (profit) information than negative (loss) information (M= .05<M= .43). Gut investors reacted more sensitively to positive (profit) information than negative (loss) information (M=- .37 < .34). Rational investors also showed more positive response to positive (profit) information than negative (loss) information (M=- .49< .04), but they did not show great expectation of profit. Based on the results of this study, the differences in investment intention among different investor types were generally insignificant. A study is meaningful in that it examines the cognitive behavioral aspect of individual investors.

이지은(Lee, Ji-Eun),이재완(Lee, Jae-Wan) 한국지방정부학회 2014 지방정부연구 Vol.18 No.1

이지은(Lee, Ji-Eun), 이재완(Lee, Jae-Wan) 본 연구의 목적은'삶의 질'에 대한 지역주민의 인식을 유형화하고 분석하는 데 있다. 지역주민의 삶의 질에 관한 주관적 인식을 분석하기 위해 Q방법론을 활용하였다. 지역주민을 대상으로 한 인터뷰 및 선행연구 검토를 통해 Q진술문을 작성하였고, P샘플은 서울시에 거주하고 있는 지역주민 40명을 대상으로 하였다. 분석 결과, 삶의 질에 대한 주민인식은 ① 기본적 요건 지향, ② 물질적 요건 지향, ③ 비물질적 요건 지향으로 유형화되는 것으로 나타났다. 본 연구는 삶의 질에 관한 인식이 지역주민마다 다를 수 있으므로, 지방자치 수준에서 숙의민주주의를 실현할 수 있는 공론의 장을 마련할 필요가 있다는 점을 시사한다. 지방정부가 지역주민들의 삶의 질을 향상시키는 정책을 수립할 때 다양한 주민들의 인식과 의견이 반영될 수 있도록 하여야 할 것이다. The objective of this study is to classify and analyze citizens' perceptions on 'quality of life'. In order to examine quality of life as perceived by citizens, Q-methodology was used. A set of Q-statements was constructed with reference to field interviews of citizens and literature review of the precedent study, and it was rated by 40 citizens residing in Seoul. The results of this study revealed that citizens' perceptions of quality of life could be classified in terms of three perspectives: 1. Basic conditions orientation, 2. Material conditions orientation, and 3. Non-material conditions orientation. Based on the analysis results, this study suggests that as citizens' perceptions of quality of life can be diverse, there is a need to develop a public sphere where deliberative democracy would be realized and advanced at local government level. By creating and developing public spheres, local governments would be able to take citizens' perceptions and opinions into account better when establishing policies for improving citizens' quality of life.

Eun-Do Kim,Jin-Kwon Lee,Jin-Kyu Cho,Jae-Myung Kim,Ji-Ho Park,Ju-Yeon Kim,Sang-Ho Jeong,Young-Tae Ju,Chi-Young Jeong,Eun-Jung Jung,Young-Joon Lee1,Soon-Chan Hong,곽승진 대한종양외과학회 2019 Korean Journal of Clinical Oncology Vol.15 No.2

Purpose: Whether subtotal or total colectomy with primary anastomosis (PA) is safer than Hartmann procedure (HP) for left-sided colon cancer obstruction or perforation remains controversial. The purpose of this study was to compare postoperative morbidity, mortality, and defecation frequency between PA and HP for left-sided colon cancer obstruction or perforation. Methods: This retrospective study enrolled 54 patients from January 2014 to February 2018 who underwent emergency surgery due to left-sided colon cancer obstruction or perforation. Results: PA was carried out in 20 patients while HP was performed for 34 patients. Thirty-day mortality did not show significant difference between the two groups (15.0% vs. 14.7%, P=1.000). No anastomotic leakage occurred in PA group while three (8.8%) cases of stump leakage occurred in HP group. Stoma repair was performed for 13 cases (44.8%) and stoma reformation was performed for one case in HP group (7.7%). Stoma related complications occurred in five cases (17.24%). For patients after stoma repair, defecation frequency at 3 months after operation was 2.91±2.88 times per day in PA group and 2.86±2.63 times per day in HP group. At 1 year after operation, defecation frequency was changed to 1.40±1.12 times per day in PA group and 1.17±0.39 times per day in HP group. Conclusion: Primary ileosigmoid or ileorectal anastomosis for left-sided colon cancer obstruction or perforation is safe, and shows similar outcome of defecation frequency compared to H

Maximizing Tendency, Purchase Involvement, and Perceptions of Online Bookstores

Lee,Gyudong,Kim,Jang-Hyun,Lee,Jae-Eun 韓國商品學會 2011 商品學硏究 Vol.29 No.6

This paper investigates the effects of the maximizing tendency (i.e., individual differences in pursuing the best option) on purchase involvement and the perceptions of Web sites. By using survey data collected from South Korea and the United States, we analyze the differences in purchase involvement, perceptions of Web sites, and intention to use between satisficers (those with low maximizing tendency) and maximizers (those with high maximizing tendency). In both samples, maximizers show higher purchase involvement than their counterparts. While the perceptions of usefulness and ease of use are significantly different between the two groups in the United States sample, we do not confirm the same pattern in the South Korean sample. We conclude with a discussion of the results and implications.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

유세포분석법으로 조사한 Orientia tsutsugamushi Boryong주의 항균제 감수성

김은실,김미경,이혜명,정문현,이진수,박재은,강재승 대한감염학회 2008 감염과 화학요법 Vol.40 No.4

Background : Scrub typhus, an infectious disease caused by Orientia tsutsugamushi, is endemic in Korea. With the introduction of tetracycline and chloramphenicol in clinical practice, the mortality due to scrub typhus has markedly decreased, In 1995, scrub typhus poorly responsive to doxycycline was reported in Thailand; the need for safe antibiotics for the treatment of scrub typhus acquired during pregnancy or for children is emerging; also, broader spectrum antibiotics having anti-Orientia activity may be preferred for empirical therapy of enteric fever syndrome and for complicated scrub typhus. The anti-Orientia activities of various antibiotics, including recently licensed antibiotics, were investigated by flow cytometry. Materials and Methods : O. tsutsugamushi strain Boryong was inoculated into the ECV304 cell line. The infected cells were stained with FS15, a monoclonal antibody reacting against a linear epitope on 56-kDa major outer membrane protein of 0. tsutsugamushi. Then the antimicrobial susceptibilities were measured by flow cytometry and expressed as a growth index (total mass of Orientia). A concentration at which no further decrease in growth index occurred was defined as the minimal inhibitory concentration (MIC). Microbial susceptibilities to the following antibiotics were measured: quinupristin-dalfopristin (Synercid), levofloxacin, ciprofloxacin, moxifloxacin, metronidazole, linezolid, clindamycin, chloramphenicol, doxycycline, azithromycin, and rifampin. Results : Considering the usual serum concentrations of rifampin (M1C=0.025-0.05 ug/mL), azithromycin (M1C=0.05-0.5 ug/mL) and doxycycline (MIC=0.05-0.1 ug/mL), these antibiotics exhibited very low MICs. Synercid (MIC=0.2-1.0 ug/mL), clindamycin (MIC=1.0 ug/mL) and chloramphenicol (MIC=1-2 ug/mL) exhibited moderately low MICs; moxifloxacin (MIC=8 ug/mL), ciprofloxacin (M1C=25.6 ug/mL or more) and levofloxacin (M1C=30 ug/mL) exhibited relatively high MICs; and cefotaxime (MIC>50 ug/mL), metronidazole (MIC>30 ug/mL) and linezolid (>30 ug/mL) exhibited high MICs. Conclusions : Among the new antibiotics, none was superior to doxycycline, azithromycin or rifampin with respect to anti-Orientia activity. Synercid, clindamycin, and moxifloxacin may show moderate therapeutic efficacies in human.

Nitric Oxide (NO), derived from L-arginine, is produced by two types (constitutive and inducible) of nitric oxide synthase (NOS: cNOS and iNOS). The NO produced in large amounts by the iNOS is known to be responsible for the vasodilation and hypotension observed in septic shock and inflammation. The inhibitors of iNOS, thus, may be useful candidate for the treatment of inflammatory diseases accompanied by the overproduction of NO. We prepared alcoholic extracts of herbal drugs which have been used for the treatment of inflammation in oriental medicine. We have screened the inhibitory activity of NO production in lipopolysaccharide (LPS)-activated macrophages after the treatment of these extracts. Among the 81 kinds of extracts of herbal drugs, 34 extracts showed potent inhibitory activity of NO production above 50% at the concentration of 50 (μg/ml. The inhibitory activities of NO production were also evaluated for several solvent fractions at three different concentrations. Especially, hexane soluble fractions of Agrimonia pilosa, Hydrangea serrata, Machilus thunbergii, Prunella vulgaris, Saussurea lappa, Tussilago farfara, and ethyl acetate soluble fractions of Angelica gigas, Ostericum koreanum, Torilis japonica, Perilla frutescence showed moderate activity at 10 and/ or 25 (μg/ml. These fractions are promising candidates for the study of the activity-guided chromatographic purification of active compounds.

The present studies were undertaken to evaluate the effect of vitamin E, CCl_4 on the change of hepatic triglyceride, hepatic cholesterol, hepatic phospholipid in male rat. The result obtained from this study were summarised as follows: 1. Hepatic phospholipid of CCl_4 treated rat was increased in proportion to CCl_4 dosage but after concomitant injection(I.P) of vitamin E and CCl_4, hepatic phospholipid was significantly decreased in comparison to that of CCl_4 alone injection. 2. There was no effect on hepatic cholesterol concentration either CCl_4 alone injection(I.P) or concomitant injecton(I.P) of vitamin E and CCl_4. 3. Hepatic triglyceride of CCl_4-treated rat was significantly increased in comparison to that of normal rat but hepatic triglyceride of rat concomitant injection of vitamin E and CCl_4 was significantly decreased in comparison to that of CCl_4 alone injection.
