  • Objective: The purpose of this study was to identify the type and frequency of chemotherapy-related prescribing errors and assess the pharmacist intervention in preventing potential harm. Methods: This study was performed in satellite pharmacy of oncology/hematology unit in tertiary teaching hospital from April to September, 2009. All chemotherapy prescribing errors detected by pharmacists were recorded. Frequency and characteristics of prescribing errors were analyzed. Pharmacists reviewed 28, 495 chemotherapy orders from 12,719 patients during 6-month periods. Results: A total of 835 prescription errors (2.93%) in 734 patients (5.77%) were detected by pharmacists. Alkylating agents (37.6%) followed by antimetabolite (23.35%), and mitotic inhibitors (21.44%) were the most prevalent classes in which errors occurs. The most common types of error detected were incorrect dose (34%), incorrect solution (33%), incorrect route (9%) and omission errors (8%). Changes in chemotherapy order due to pharmacists' intervention occurred in all error cases. Conclusion: Pharmacists' intervention in reviewing chemotherapy and drug orders intercepted potential harm due to prescribing errors. The current study provided strategies for reduction of medication errors.

  • Biomarkers could be critical and useful tools for assessing the biological effects of smoking and detecting differences between potentially reduced exposure product (PREP) and conventional cigarettes. Smoking-related biomarkers can be classified into three categories as biomarkers of exposure, biomarkers of effects, and biomarkers of potential harm. When compared with the biomarkers of effects or harm, the biomarkers of exposure for chemical constituents of cigarette smoke are well established and characterized. In addition, they could offer the important information in understanding how cigarette smoke interacts with biological molecules and causes the disease to human. Therefore, we provide an overview of 6 biomarkers of exposure (Nicotine and nicotine metabolites, Carboxyhaemoglobin, NNAL (4-(methylnitrosoamino)-1-(3-pyridyl)-1-butanol) and NNAL - glucuronide, 3-Hydroxypropyl-mercapturic acid, and Monohydroxy-butenyl-mercapturic acids, and Urine mutagenicity) which were validated through extensive research and clinical experience. These reliable biomarkers could help identify the efficacy of PREP by predicting early toxicological effects and lead to improve it.

  • Purpose: This study was done to examine levels of temperament, parent-child attachment and depression of adolescents and verify its effects. Methods: Surveys were conducted with 500 students from two middle schools, one located in Seoul and one in Gyeonggi Province. Adolescent temperament was measured using the Junior Temperament and Character Inventory, parent-child attachment using the Revised Inventory of Parent and Peer Attachment and depression using the Children's Depression Inventory. Cluster, t-test, correlation and logistic regression were used for data analysis. Results: Characteristics of temperament were classified into 2 groups. The 'Adaptation vulnerable group' showed high Harm Avoidance and the 'Adaptation protective group' showed high Reward Dependence, and Patience. The 'Adaptation vulnerable group' showed lower attachment and higher depression than the 'Adaptation protective group'. Novelty Seeking and Harm Avoidance correlated positively with depression and negatively with attachment. Students with higher levels of attachment reported lower levels of depression. The logistic regression analysis showed that the 'Adaptation vulnerable group' was 2.16 times more likely to be affected by depression than 'Adaptation protective group'. Conclusion: Results of this study can be used to develop depression intervention programs for adolescent psychological health and provide encouragement in the development of parent-child attachment.

  • This study investigates the performance of four Bayesian methods, Random Walk Metropolis (RWM), Hit-And-Run Metropolis (HARM), Adaptive Mixture Metropolis (AMM), and Population Monte Carlo (PMC), for estimating the parameters and uncertainties of probability rainfall distribution, and the results are compared with those of conventional parameter estimation methods; namely, the Method Of Moment (MOM), Maximum Likelihood Method (MLM), and Probability Weighted Method (PWM). As a result, Bayesian methods yield similar or slightly better results in parameter estimations compared with conventional methods. In particular, PMC can reduce parameter uncertainty greatly compared with RWM, HARM, and AMM methods although the Bayesian methods produce similar results in parameter estimations. Overall, the Bayesian methods produce better accuracy for scale parameters compared with the conventional methods and this characteristic improves the accuracy of probability rainfall. Therefore, Bayesian methods can be effective tools for estimating the parameters and uncertainties of probability rainfall distribution in hydrological practices, flood risk assessment, and decision-making support.

  • Algal organic matters (AOMs) are challenging to remove using traditional water treatment methods. Additionally, they are recognized as disinfection by product (DBP) precursors during the chlorination process. These compounds have the potential to seriously harm aquatic creatures. Despite the fact that AOMs and DBPs formed from algae can harm aquatic species by impairing their cognitive function and causing behavioral problems, only a few studies on the effects of AOMs and associated DBPs have been conducted. To assess the impact of extracellular organic materials (EOMs) produced by three different hazardous algal species and the chlorinated EOMs on zebrafish, this study used fish acute embryo toxicity (FET) and cognitive function tests. With rising EOM concentrations, the embryo's survival rate and mental capacity both declined. Of the three algal species, the embryo exposed to Microcystis aeruginosa EOM exhibited the lowest survival rate. On the other hand, the embryo exposed to EOMs following chlorination demonstrated a drop in CT values in both the survival rate and cognitive ability. These findings imply that EOMs and EOMs treated with chlorine may have detrimental effects on aquatic life. Therefore, an effective EOM management is needed in aquatic environment.

  • 연구목적: 고등학생을 대상으로 계절성 평가 도구인 계절성 양상 평가 설문지(Seasonal Pattern Assessment Questionnaire, SPAQ)와 인격 성향을 평가하는 기질과 성격 검사(Temperament and Character Inventory, TCI)와의 상관관계에 대해 조사하여 계절성과 인격 구조와의 유전적 요인과의 관계에 대해 알아보고자 하였다. 방법: 서울에 거주하는 600명의 고등학생을 대상으로 Rosenthal의 SPAQ와 Cloninger의 TCI 한국어판을 사용하였다. 결과 : 여학생은 harm avoidance, reward dependence, cooperativeness에서 높은 점수가 나온 반면 남학생에서는 persistence, self-transcendence에서 높은 점수가 나왔다. 총계절성 점수(Global seasonality score)와 TCI의 하부척도를 비교한 결과 harm avoidance, self-transcendence와는 정적 상관관계가 나타났으며, self-directedness, cooperativeness와는 부적 상관관계가 나타났다. 로지스틱 회귀분석 결과, SAD의 경우 회귀계수는 self-directedness와 유의한 부적 상관관계가 나타났으며 self-transcendence와는 정적 상관관계가 나타났다. S-SAD의 경우에는 cooperativeness와 부적 상관관계를 보였으며 self-transcendence와는 정적 상관관계를 보였다. GSS가 11점 이상일 경우에는 그렇지 않은 경우에 비해 self-transcendence 점수가 높게 나타났으며, 겨울에 가장 기분이 저하되는 경우에는 그렇지 않은 경우에 비해 더 낮은 cooperativeness 점수를 보였다. 계절성 변동이 중등도 이상의 문제를 일으키는 경우에는 높은 harm avoidance, self-transcendence 점수를 보였다. 결론: 계절성과 성격 및 기질적인 부분이 서로 연관성을 보였다. 이 연구가 우리나라에서 고등학생을 대상으로 한 최초의 연구로서 여기에서 보인 결과들은 임상적 적용에 도움을 줄 수 있을 것으로 보인다.

  • 阿拉伯人联合抵制丹麦产品, 澳大利亚人联合抵制法国产品, 而中国人厌恶日本产品, 这些是国家间的敌对行为影响消费行为的案例. 敌意文献中已考查过消费者对其他国家敌对行为的反应, 以及这种敌意如何影响消费者对敌对国家产品的态度和倾向. 例如, 中国消费者不愿购买日本产品, 是由于日本人在第二次世界大战中的暴行, 以及不平等的经济往来(Klein, Ettenson and Morris 1998). 然而在市场营销文献中, 却没有考查过那些对他国实施敌对行为的国家消费者的反应, 这些敌对行为是否会影响他们购买受害国产品的态度. 社会心理学文献认为, 消费者面对这样的敌对行为时, 会产生一种集体犯罪感. 集体犯罪感源于当组织成员认为组织要对伤害其他组织的行为负责时所产生的痛苦感(Branscombe, Slugoski, and Kappenn 2004). 案例包括美国人由于美军在Abu Ghraib监狱的暴行而产生犯罪感(Iyer, Schamder and Lickel 2007), 荷兰由于过去对印度尼西亚的占领而产生犯罪感(Doosje et al. 1998). 本研究的主要目的是考查当国家成员对他国有敌对行为时消费者的感知, 这种感知是否会影响他们对敌对国家产品的态度. 更准确的说, 本研究的目标之一是考查集体犯罪感的感知前提, 以及当国家成员对他国有敌对行为时, 人们的情绪反应. 另一个目标是考查集体犯罪感如何影响消费者对敌对国产品的感知和倾向. 如果集体犯罪感能起到明显的预言作用, 敌对国双方的公司可能会从这类不幸的事件中受益. 本研究利用了由Klein, Ettenson and Morris (1998)提出并经Klein (2002)发展的敌意模式. Klein发现美国消费者对日本人怀有敌意, 起因是二战期间的事件(如日军偷袭珍珠港)和近年来日本的经济威胁. 因此本研究认为, 二战间的事件(如广岛长崎的原子弹爆炸)可能导致美国消费者的集体犯罪感. 曾有过一系列的三个假设, 第一个假设关于集体犯罪感的前提. 之前有研究认为当消费者感知到侵害造成的非法伤害, 并且认为侵犯者来自的国家应为此负责, 集体犯罪感就产生了(Wohl, Branscombe, and Klar 2006). 因此提出下列假设: 假设1a: 感知到的伤害非法性越高, 集体犯罪感越强烈. 假设1b: 责任越大, 集体犯罪感也肯定越强烈. 第二个和第三个假设关于集体犯罪感对倾向日本产品的影响. Klein (2002)发现对日本的敌意越强, 相比较韩国产品对日本产品的倾向越小, 但相比较美国产品对日本产品的倾向并未变小. 这些结果说明集体犯罪感存在时, 消费者在购买日本产品和韩国产品时会更倾向于前者, 但在购买日本产品和美国产品时并未受影响. 假设2: 集体犯罪感与购买日本产品的倾向大于韩国产品有关, 但与购买日本产品的倾向大于美国产品无关. 假设3: 集体犯罪感与购买日本产品的倾向大于韩国产品有关, 并且对产品的判断和敌意保持不变. 有过一个实验测试这个假设. 使被调查者面临发生在二战中的敌对事件, 从而产生非法伤害和责任. 该实验由一家美国的消费者调查小组收集数据, 将调查对象随机分配到低等级责任和违法情况(n=259)或高等级责任和违法情况(n=268). 测试假设关系时, 运用到潜在变量结构方程模式(LVSEM). 第一个假设得到了支持, 美国人因二战中对日本人的伤害而产生的伤害非法性和责任都对集体犯罪感有积极影响. 第二个假设也得到了支持, 集体犯罪感与购买日本产品的倾向大于韩国产品有关, 但与购买日本产品的倾向大于美国产品无关. 最后, 第三个假设也得到了支持, 集体犯罪感与购买日本产品的倾向大于韩国产品有关, 同时还影响人们对日本产品的判断和敌意. 由这些研究的结果可得出结论. 第一, 伤害的非法性和责任是集体犯罪感的前提. 第二, 当消费者面临来自敌对行为目标国家的产品和其他外国产品之间的选择时, 会受到集体犯罪感的影响. 但当他们面临来自敌对行为目标国家的产品和本国产品时, 不受集体犯罪感的影响. 这一结果意味着当竞争对手来自国外时, 利用集体犯罪感对那些受到敌对行为的国家的公司是可行的, 但当竞争对手来自国内时则不可行.
