Regulatory reform in the era of new technological development: The role of organizational factors in the public sector

What is the role of organizational factors in fostering regulatory reform in response to new technological development? Existing studies provide useful frameworks to understand regulatory reform in rapidly changing circumstances but still lack a systematic analysis of how organizational factors affect regulatory reform in the public sector. To fill this gap, we examine the impact of several institutional elements that are central to defining organizational characteristics, such as job tasks, bureaucratic autonomy, and organizational culture. We theorize that regulatory reform is more likely when public sector organizations are more receptive to external changes, which are determined by these characteristics. We leverage original surveys from over 1,000 civil servants in Korea, one of the front runners in new technological development, and find support for our prediction. We find that the implementation of regulatory reforms is more likely when (i) organizational tasks are relevant to scientific and technological development, (ii) higher levels of bureaucratic autonomy are granted, (iii) agency heads demonstrate stronger leadership, and (iv) organizational culture is less authoritarian. Our study makes clear contributions to the literature on public management and regulation theory, and has important implications for regulatory reform in the face of new technological development.     

Distribution of methamphetamine and amphetamine in drug abusers’ head hair

In order to aid the interpretation of hair results from methamphetamine (MA) abusers the MA and amphetamine (AP) concentrations in 2070 hair samples were statistically evaluated. The MA and AP concentrations in hair were put into three groups arbitrarily representing low, medium and high ranges and the metabolite-to-parent drug ratios of each group were examined. The concentration ranges proposed here were also applied to the interpretation of five authentic cases. The low, medium and high ranges of MA were 0.5–4.2, 4.2–24.5 and 24.5–608.9 ng/mg and those of AP were 0.1–0.4, 0.4–1.7 and 1.7–41.4 ng/mg. The AP-to-MA ratios showed large variation but a tendency that it decreased as the MA ranges increased. This evaluation was very useful to presume the severity of individuals’ MA abuse and to provide law enforcement agencies more understandable information. It could also facilitate the court's decision regarding specific circumstances surrounding the drug-related crimes.     

Sequences of the Cytochrome C Oxidase Subunit I (COI) Gene are Suitable for Species Identification of Korean Calliphorinae Flies of Forensic Importance (Diptera: Calliphoridae)

Abstract:  Calliphorinae fly species are important indicators of the postmortem interval especially during early spring and late fall in Korea. Although nucleotide sequences of various Calliphorinae fly species are available, there has been no research on the cytochrome c oxidase subunit I (COI) nucleotide sequences of Korean Calliphorinae flies. Here, we report the full-length sequences of the COI gene of four Calliphorinae fly species collected in Korea (five individuals of Calliphora vicina , five Calliphora lata , four Triceratopyga calliphoroides and three Aldrichina grahami ). Each COI gene was amplified by polymerase chain reaction and directly sequenced and the resulting nucleotide sequences were aligned and analyzed by MEGA4 software. The results indicate that COI nucleotide sequences can be used to distinguish between these four species. Our phylogenetic result coincides with recent taxonomic views on the subfamily Calliphorinae in that the genera Aldrichina and Triceratopyga are nested within the genus Calliphora .     

Age estimation of Korean children based on dental maturity

The aim of this study was to evaluate the relationship between age and dental maturity and to establish the standard database of dental maturity based on the Demirjian's stages, which can be used for the age estimation of Korean children. For this purpose, dental maturity was measured by the Demirjian's stages on a randomly selected sample of panoramic radiographs taken from 2706 patients between 1 and 20 years of age and analyzed by multiple linear regression analysis based on the method of least squares. The results showed that, except for the third molars, the development of permanent teeth in Korean children was more advanced in females. The Demirjian's stage G of the second molar appeared last in both male and female subjects by age 18, showing 95th percentile at age in the male and female subjects between 16.7-17.4 years and 17.1-17.3 years, respectively. Coefficients of determination (r(2)) of the Demirjian's stages relative to age in regression analysis were 0.9721 in male and 0.9740 in female subjects. The standard error was 0.63 years in male and 0.62 years in female subjects. The estimated age according to regression analysis was within +/-1.0 year of the actual age in 92.0% of male and 92.5% of female subjects. Collectively, the data of the present study can be used as a reference for dental maturity and a standard for age estimation of Korean children.     

Mortgage Choice in Rural Housing

Rural homeownership is promoted in the United States by mortgage insurance programs administered by the federal government. We analyze the choice between assistance offered by two such agencies: the Federal Housing Administration and the Rural Housing Service (RHS). We find applicants are sensitive to the relative annual mortgage insurance premiums and guarantee fees. However, there are also persistent racial differences as well as institutional effects. We also find the application and origination process is substantially longer in the RHS program, but variation in closing times does not clearly impact mortgage choice.     

“参与式政府”的构筑——韩国卢武铉政府行政改革综述

行政改革曾经是卢武铉政府执政伊始即推出的众多雄心勃勃的施政目标之一。早在2003年2月25日的总统就职演说中,卢武铉即提出了建立"参与式政府"的愿望,为此新政府将严格奉行"原则与信任、公正与透明、对话与妥协、分权和自律"四大原则进行施政。为了将"参与式政府"的愿景转化为现实,卢武铉政府设立了五大行政改革目标,即效率的行政、服务的行政、透明的行政、清廉的行政和参与的行政。构筑参与式政府实质是卢武铉政府在新世纪初通过对国内政治、经济、社会环境的通盘考量,将民众要求完善民主、参与国家政治、获得更多优质公共服务的要求与政府提高自身能力、增强国家综合实力的目标相结合的一次创新尝试。
