血縁主義の弊害 : 日本の同族企業のデータを用いた実証分析

本稿では能力の有無にも関らず血縁関係で新規経営者になるという意味での血縁主義がどのような結果をもたらすかについて，日本の同族企業のデータを用いて実証分析した。学歴を能力の代理変数として，エリートか非エリートかを区分して，非エリート親族承継をその他の様々な事業承継のタイプと比較した。単純なDD (Difference-in-Differences)分析，幾つかの要因を制御したDD分析の結果，非エリート親族承継は婿・婿養子承継及び非同族企業の専門経営者承継に比べて経営者交代前後で業績の悪化が生じていた。このような業績の違いが能力の不足からではなく，新規経営者になるまでの経験の差異からくる可能性を探るため，経験の経路を制御した回帰分析を行いDD分析と同じ結果を得た。よって，業績の差異は経験の違いからではなく低い能力から生じたと判断される。最後に，事業承継がランダムイベントではないので因果関係を強く主張できない問題点を解決するために，操作変数法を用いた分析を行った。操作変数法の結果はDD分析の結果とほぼ同じ結果を示し，より明確な因果関係として血縁主義によって経営者交代前後で企業業績の悪化が生じていた。同族企業, 事業承継, 血縁主義

METHODS The differences of Amomum villosum and Jian Amomum villosum were discussed from several aspects, such as ancient records, source, geographical distribution, appearance, microstructure,chemical composition and uhraviolet spectrum. RESULTS Amomum villosum and the construction of Jian Amomum viUosum in the source, the geographical distribution, appearance, microstructure, chemical composi- tion and medicinal efficacy and other aspects are different. CONCLUSION According to the characteristics of plants, microscopic physical and chemical identification and UV spectroscopy, it is possible to identify Amomum villo- sum and Jian Amomum villosum

差示扫描量热法对5种硫酸盐类矿物药的分析鉴别研究

目的:采用差示扫描量热法(differential scanning calorimetry,DSC)对芒硝、生石膏、玄明粉、白矾及寒水石等5种硫酸盐类矿物药进行分析鉴别,以探讨DSC法快速鉴别硫酸盐类矿物药的可行性。方法:收集不同来源的芒硝、生石膏、玄明粉、白矾及寒水石,共30批样品,考察升温范围、升温速率2个因素对DSC的影响,并在最佳条件下通过DSC图谱区分5种硫酸盐类矿物药。结果:升温范围30～400℃,升温速率40℃/min为DSC法快速鉴别5种硫酸盐类矿物药的最佳条件。芒硝有4个明显吸热峰,峰形拐点分别为(41±1)、(111±4)、(219±4)及(255±1)℃;生石膏有2个明显特征峰,(185±3)℃为吸热峰温,(381±2)℃为放热峰温;玄明粉有2个明显吸热峰,峰形拐点分别为(227±5)、(257±2)℃,与芒硝后2个峰接近;白矾有3个明显吸热峰,峰形拐点分别为(100±1)、(121±2)及(249±1)℃;寒水石在400℃范围内无明显特征峰。结论:DSC法具有操作简便、测量快速、重现性好、谱图易解析和样品用量少等优点,可快速鉴别硫酸盐类矿物药

Analysis of 3 291 Outpatient Prescriptions of Traditional Chinese Medicine in Our Hospital

目的:了解我院门诊中药处方用药情况,找出处方用药规律及存在问题,为中药房工作和中医临床用药提供参考。方法:抽取我院门诊2013年每月3个工作日的中药处方共3 291张,从处方书写规范性、用药合理性、中药使用情况等方面进行统计分析。结果:我院中药处方在临床诊断、用药疗程、用法用量等方面存在问题,平均处方金额为76.21元、平均药味为10.14种,甘草使用率最高,补益药使用量最大。结论:我院中药处方合理性存在一定问题,单方剂量偏大、药味偏多,但金额适中。亟需国家相关管理部门和医院重视和加强对中药处方的管理,制订切实有效的管理办法,促进中药临床合理应用。OBJECTIVE:To investigate the outpatient use of traditional Chinese medicine so as to find out the regularity and the problems in drug use in our hospital for references of pharmacy and clinical medication of traditional Chinese medicine.METHODS:3 291 outpatient prescriptions of traditional Chinese medicine collected in every 3 working days in each month of 2013 in our hospital were analyzed statistically with regard to the standardization in prescription writing,rationality in drug use and the utilization data of traditional Chinese medicine.RESULTS:The outpatient use of traditional Chinese medicine in our hospital had problems in clinical diagnosis,course of treatment,dosage & administration etc.The average consumption sum was 76.21 yuan per prescription and an average of 10.14 drugs were prescribed with licorice used most frequently and reinforcing drugs ranked the first in terms of consumption amount.CONCLUSIONS:The use of traditional Chinese medicine in our hospital was irrational in that the dosage of simple recipe and the number of drugs per prescription were on the high side although with rational consumption sum.It is urgent for the related management departments of our country and hospital to attach great importance to strengthen management on the prescriptions of traditional Chinese medicine and formulate effective administrative measures management to promote clinical rational use of traditional Chinese medicine
