The aim of this study is to report 2 cases of acute promyelocytic leukemia who died from intracranial hemorrhage following leukapheresis and to provide proper preventive measures against hemorrhage following leukapheresis. From 1994 to 1997, a total of twenty-six patients with leukemia underwent leukapheresis to control hyperleukocytosis at Ajou University Hospital. Two patients with acute promyelocytic leukemia received all-trans retinoic acid but developed drug-induced hyperleukocytosis. Shortly after leukapheresis, they died from intracranial hemorrhage. The risk factors for fatal hemorrhage are thought to be coexisting disseminated intravascular coagulation(DIC), thrombocytopenia aggravated by leukapheresis, exacerbated coagulopathy related to mechanical trauma through leukapheresis and the excess use of citrate during leukapheresis. To reduce the risk of the bleeding associated with leukapheresis, it is necessary to replace platelet sufficiently before and after leukapheresis and to give calcium to correct coagulopathy induced by excess citrate which is used as anticoagulant as well as the correction of disseminated intravascular coagulation.

색시톡신에 의한 마비독성 패류 중독 2예

최상천,박종석,정윤석 대한응급의학회 2001 대한응급의학회지 Vol.12 No.4

Paralytic shellfish poisoning results from consumption of mollusks that have fed on dinoflagellates capable of producing neurotoxins such as saxitoxin. The saxitoxin is concentrated in the shellfish and acts by decreasing sodium-channel permeability, thereby blocking neuronal transmission in skeletal muscles. Symptoms including paresthesia, perioral numbness, perioral tingling, nausea, vomiting, extremity numbness, extremity tingling, dizziness, ataxia, dysphagia, and weakness have been reported. In serious cases, respiratory hold may occur up to 6∼24 hours after ingestion. Generally, the treatment for paralytic shellfish poisoning is supportive care, but mechanical ventilation is needed in serious cases acompanied by respiratory hold. We experienced two cases of paralytic shellfish poisoning. Respiratory hold was presented in one case and only mild paresthesia in the other case. After supportive management, including mechanical ventilation in former case, both patients were discharged without sequalae.

How Young Consumers Perceive Firms’ Environment, Social, and Governance (ESG)

Choi,Woo Jin,Yoon,Ho-Jung 한국상품학회 2021 商品學硏究 Vol.39 No.6

Demand for ESG is surging. However, not many are known regarding how consumers perceive firms’ ESG. To fill this gap in the literature, the current research seeks to explore how firms’ ESG is perceived by the young generation as well as to explore how the young generation perceive South Korean firms from the ethical perspective. For this purpose, we surveyed ninety-two respondents (35.8% male; Mage=23.5) and they completed the survey. In the survey, respondents indicated their perception regarding South Korean firms’ ethical business management and South Korean firms’ ESG management. Most respondents said ESG would be important (88%) and helpful to achieve competitive advantage (81.5%). However, interestingly, almost of respondents (46.7%) said that ESG would be helpful to maximize productivity. Rather, 92.4% of respondents perceived that ESG would be helpful to enhance firms’ images. In addition, they also perceived that the importance of ESG would become great in the future (85.9%) enough to make a significantly positive impact on firms’ productivity (72.8%). In addition to these findings about ESG, we further investigated how this young generation perceived the ethical business climate among South Korean companies. The results show that only 17.3% of respondents said South Korean business is ethical and 70.6% thought ethical problems would be a problem in the future. While the investigation for South Korean consumers’ perception of ESG and ethical business is not many, our work makes a significant theoretical contribution by providing empirical evidence on this issue. Our results are also managerially meaningful by being a reference to South Korean companies as well as global companies who are interested in the Korean market.

최보가,張允玉,金貞姬 慶北大學校 師範大學 1987 敎育硏究誌 Vol.29 No.-

Sex-role development is one of the essential tasks of child development and a part of one's personality. Many studies have been undertaken to examine the children's sex-role preference and verified the difference between boys and girls. There are many factors that effect on the children's sex-role preference. For example, there is home environment that is included parents, -family structure, home's social level, brothers and sisters' formation and birth-rank,... etc. Also, there is social environment that is included peer, teacher and mass media. But we can expect that preschool children are most effected by parents. Thus the present study was undertaken to examine the influences of father dominance on preschool children's sex-role preference. This study is aimed to find out the follows facts. 1. Degree of father dominance that is perceived by child. 2. To find out father dominance has any influence on the boy's sex-role preference. To find out father dominance has any influence on the boy's sex-role preference under each of four lowranking domains, that is, decision-making, competence, nurture and limit setting. 3. To find out father dominance has any influence on the girl's sex-role preference. To find out father dominance has any influence on the girl's sex-role preference under each of four lowranking domains, that is, decision-making, competence, nurture and limit setting. The dependent measures are 1. Toy Preference Test. 2. Father dominance examination used Father Dominance Test (Henry, B. H.) Subjects were obtained from 100 boys and 100 girls, that they were all preschool children in Daegu. For statistical analysis, Mean, the Standard Deviation, t-test, one way ANOVA and Scheffe's test were used. The levels of significant were established at 0.05 and 0.01. The results were as follows 1. Generally, both boys and girls have perceived father dominant more than mother. In case of boys, they perceived father dominant more than mother in domains of decision-making and competence. In case of girls, they perceived father dominant more than mother in domains of decision-making, competence and nurture. 2. Father dominance perceived by young children had effects on boy's sex-role preference. In general, the higher father dominance was, the higher boy's masculinity was. In domains of decision-making, competence and nurture, father dominance have significant influences to boy's sex-role preference, but in domain of limit-setting, father dominance have no significant influence. 3. Father dominance perceived by young children had effects on girl's sex-role preference. In general, the higher father dominance was, the higher girl's feminity was. In domains of decision-making and limit-setting, father dominance have significant influences to girl's sex-role preference, but in domains of nurture and competence, father dominance have no significant influence on the girl's sex-role preference.

최정윤,정규림 대한치과교정학회 1998 대한치과교정학회지 Vol.28 No.4

본 연구는 교정치료를 목적으로 발치가 예정된 치아를 대상으로 임상적으로 매우 중요한 치료과정 중의 한 부분인 초기치아배열단계에서 다양한 기간과 크기의 교정력을 가하여 치아배열기간, 교정력의 크기, 치아이동방향에 따라 치근표면에 일어나는 흡수와 회복 양상에 대한 정보를 얻기 위하여 시행되었다. 치료받지 않은 13개의 치아를 대조군으로 하고 교정치료계획상 제1소구치를 발거하기로 예정된 37개의 치아를 실험군으로 하여 20-450gm의 초기교정력을 가한 후 주사전자현미경적 관찰을 통하여 다음과 같은 결과를 얻었다. 1. 실험군 37개 중 22개의 치아(59.5%)에서 치근흡수가 발견되었다. 치근흡수는 최소실험기간인 3주군부터 나타났으며 흡수부위의 회복은 3개월군부터 나타났다. 2. 교정력의 기간 증가에 따라 치근흡수의 발생빈도가 증가하는 경향을 보였다. 3. 교정력이 클수록 상아질을 포함하는 흡수가 증가하는 경향을 보였다. 4. 치근 흡수의 부위는 하중 받는 부위와 일치하는 경향을 보였다. 5. 치근 흡수 부위는 면적과 가장 상관성이 높은 변수는 교정력의 크기였다. The purpose of this study was to investigate the root resorption and repair pattern of human teeth according to the force magnitude, direction and duration during the initial leveling and alignment phase. 40gms to 500gms of force applied to the 37 experimental teeth with duration of 3 weeks to 7 months. Then, the experimental teeth were extracted. 13 control teeth were extracted without treatment. The results are as follows: 1. 59.5% of 37 teeth exhibited root resorption. The initial resorption site was visible at the apex within 3 weeks with 100 gms samples, and the initial repair site was visible at the apex within 3 months with 400 gms samples. 2. Number of resorbed teeth increased with the duration of the force. 3. The depth of the resorption increased with the magnitude of the force. 4. The areas of resorbed root corresponded with the loading pattern. 5. The areas of resorbed root were highly correlated with the magnitude of the force. The result of this study suggest that root resorption could occur during the initial leveling and alignment phase. These initial injuries are all small and insignificant. It is the extensive type of apical root resorption that must be regarded as deleterious to the function and stability of the tooth moved. During the initial leveling and alignment phase lighter force of the interrupted type and short treatment period would be favorable with regard to avoidance of root resorption and repair of resorbed root surface.

Excretory urography is a type of contrast study used to verify and localize upper urinary tract disease. It is an inexpensive and easy way to visualize of anatomic and functional status of the kidney and has been used as a primary imaging modality for the evaluation of urinary tract abnormalities. We describe urological signs of 7 dogs who examined with excretory urography and ultrasonography. Six cases were referred to veterinary medical teaching hospital. Chungnam national university (VMTH, CNU) to evaluate renal function after the treatment for renal failure and one case was referred showing hematuria. In case 1, 2 and 4, blood test and urinalysis was normal and the results of excretory urography presented that renal function were normal range. In case 3, the results of urinalysis, ultrasonography, and excretory urography except blood test presented abnormal kidney and hydronephrosis was diagnosed. In case 5 and 6, blood test, urinalysis, ultrasonography and excretory urography indicated renal failure. In case 7, blood test, urinalysis and ultrasonography presented partially abnormal signs, however, the results of excretory urography was normal range.
