Background: The purpose of this study was to investigate the current status of medication compliance of outpatients and to analyze the factors contributing to mediation non-compliance. Methods: Telephone survey was conducted to the 1,000 outpatients who visited medical institution during the period from January 2002 to April 2002. Subjects were randomly selected from the telephone directories of the nation, and the socio-demographic characteristics of the respondents such as age, gender and region were matched based of those of outpatients in 2001. Results : The results of survey reveals that those who complied with doctors' regimen in the right way accounted for 82.4%. The compliance increased with the strong belief in the medication, less unwanted side effects and inconvenience, more severity of disease, and lower perceived health status. Compliance rate was also higher in the patients group who experienced the drug education by the pharmacists than those who did not. Conclusion: In order to improve drug compliance, drug information on efficacy, adverse reaction, drug interactions, and basic disease information are to be provided to the patients. Drug education needs to be focused not only on providing knowledge of drugs and diseases but also changing attitude on drug use of the patients.

자본구조이론에서의 현금흐름재정거래

이의경 한국경영교육학회 2004 경영교육연구 Vol.36 No.-

M & M in their classic capital structure article focus on using homemade leverage to show that similar companies must have the same value according to the law of one price. In this article focus is shifted to the investors’ cash flow. By keeping the cash flow to the investor constant, an arbitrage profit can be identified. Again, according to the law of one price the value of the similar firms must become equal. 완전시장에서의 MM이론은 동일레버리지수준을 유지하는 방법으로 재정거래를 설명하고 있다. 이를 통해서 미래현금흐름이 동일한 두 기업의 가치가 똑같게 평가되어 일물일가법칙이 성립한다는 것을 보이고 있다. 그러나 그 내용이 어려워서 재무이론을 처음 접하는 학생들이 이 방법을 쉽게 이해할 것이라고 기대하는 교육자는 별로 없는 실정이다. 본 논문은 분석의 초점을 투자자의 레버리지 대신에 현금흐름에 두고 재정거래를 설명하는 방법(현금흐름재정거래)을 제시한 것이다. 이 방법은 종전의 MM방법과 동일한 결과를 얻으면서도 수식에 크게 의존하지 않는 직관적 방법이다. 따라서 교육현장에서 MM이론을 보다 쉽게 이해시킬 수 있는 방법이 될 것이라고 생각한다.

不完全市場에서의 分散投資와 企業價値 : 代理費用을 中心으로

李義景,李相雨 대진대학교 1995 大眞論叢 Vol.3 No.-

The advantages of diversification are considered in two respects : operational and financial diversification effects. The first caused by ① reduction of production cost through producing technologically related products ② enhancing competitive sales position through producing various kinds of products ③ synergy effect in R&D. This opreational effect certainly increases firm value. But as for the financial diversification, under perfect market, it has no effect on firm value. The purpose of this paper is to explain the relation of financial synergy effect and firm value under imperfect market. In first half, traditional imperfect factors(asset indivisibility, bankruptcy cost and tax) are considered. Considering these factors, financial synergy effect proved to be positive on firm value. In latter half, financial synergy effect is analyzed under asymmetric information between firm and investors. The analysis focused on agency cost between the principal and agent, comes to the conclusion that diversification increases firm value.

李儀卿,孫仁子,趙南春,金洛斗,兪炳卨 한국병원약사회 1987 병원약사회지 Vol.4 No.1

藥劑部의 業務는 전통적인 散劑·調劑業務로부터 調劑·製劑·醫藥品 情報·品質管理·注射劑 混合 및 藥物 動態學的 硏究등 다양한 내용으로 發展되고 있다. 그러나 現 醫療法에서의 藥劑部 人力 算定 基準은 調劑業務에 국한된 실정이다. 따라서 現在 서울대病院 藥劑部 각 부서의 業務에 所要되고 있는 業務量 및 人力의 現況을 分析함으로써, 藥劑部 適正人力 算出의 根據를 提示해 보고자 하였다. 産業工學 硏究方法論 中 하나인 WORK-SAMLLING法을 서울大 病院 藥劑部 業務에 適用하여, 細分된 各 業務를 處理하는데 所要되는, 時間 百分率을 구했다. 대상으로는 外來藥局·病室藥局 調劑室을 各 2週間, 實驗情報室·藥務課·在庫 管理課를 各 1週間, 10分 間隔으로 觀察하여 總 30414回의 觀察資料를 統計處理했다. 그 結果, 서울大 病院 藥劑部 藥師의 業務 比率은. 調劑(64.5%), 製劑(7.3%), 實驗情報(19.9%), 藥務(2.8%), 在庫管理(5.4%)로 나타났다. 處方箋 한枚를 處理하는데 所要되는 平均時間은, 調劑 System의 影響을 받아서 錠散劑의 境遇, 一人一處方制로 調劑하는 外來藥局에서는 7분 54초, 分擔式인 病室藥局에서는 5분 51초였는데, 이를 根據로 適正人力을 算出할 수 있다. 또한 하루동안 接受된 處方箋을 處理하기 위하여, 調劑室 藥師만으로는 1人當 183.74件, 本院 全藥師로는 125.03件의 業務가 割當되는데, 이는 醫療法 基準보다 過多한 業務量이라고 할 수 있다. The roles of hospital pharmacy are expanded from traditional dispensing services into manufacturing, drug information, quality control, Ⅳ admixture, and kinetic studies. By current medical law, manpower requirement standards of hospital pharmacy are limited to dispensing services. So the original objective of this study was to develop a tool to evaluate, quantitiate, and document the manpower requirements necessary to adequately staff the pharmacy department. One of the industrial engineering study techniques, worksampling study, was applied to the workload and staffing patterns of a pharmacy in 1497-bed hospital, Seoul National University Hospital Pharmacy. Twenty-five defined activities of pharmacists and aids were observed. Observations were taken and categorized every 10 minutes. No attempt was made to disguise data collection. A total of 30414 observations were made. Percentages of total time spent dy pharmacists were : ⑴ dispensing activities, 64.5%; ⑵ manufacturing activities, 7.3%; (3) drug information activities, 19.9%; ⑷ administration activities, 2.8%: ⑸ inventory activities, 5.4%. Dispensing system had an effect on the mean time required to perform one prescription. The mean time for the outpatient pharmacy by one pharmacist-one prescription dispensing system was 7 minutes 54 seconds, while for the inpatient pharmacy by division dispensing system was 5 minutes 54 seconds. These data provided a basis for determining manpower requirements. To perform prescription processed during day, 183.74 cases were assigned per pharmacist in dispensing area, and 125.03cases per pharmacist in whole pharmacy. These results seemed to be heavier than current medical law standards. (1 sheet of prescription=2.03cases of prescription)

負債의 옵션條項이 代理問題에 미치는 效果

李義景 대진대학교 1995 大眞論叢 Vol.3 No.-

Information economics consists of two major fields : agency theory and signalling theory. Agency theory deals with goal incongruency as well as information asymmetry between the principal and agent. Agency cost, measured by welfare loss in agency problem, is defined in various agency relationship aspects. For instance, perquisite consumption, risk incentive, underinvestment incentive, bankruptcy cost and so forth. The main theme of this paper is risk incentive. And the primary purpose is to explain the effect of the option provisions in debt on the risk incentive. For this purpose, Black-Scholes OPM is used in analysing option provisions of various derivative debts. Because option provisions in debt are basically contingent claims and OPM is a general pricing model of the contingent claims. Using OPM, this paper describes the effects of option provisions in debt on the risk incentive by mathematical method. Analytical results show that conversion provision, call provision and stock warrant provision in debt reduce or eliminate the risk incentive, but stock right provision increases it.
