Japan's military research and development: A high technology deterrent

Abstract

This article examines the increased linkage between domestic and foreign policy that has been a consequence of democratization and globalization in Korea. It argues that while prior to 1987 foreign policy-making saw very little public input, and while democratization did not lead to a weakening of domestic political institutions nor a rise in nationalism, it did open up domestic political space where foreign policy-making increasingly became part of the contentious electoral competition. The globalization policy, initiated with the purpose of raising Korea's international status, which has remained a goal of succeeding administrations, created a complex interdependency which led to a breakdown in the separation between the domestic and international, and that often brought with it a domestic backlash. As a consequence foreign policy-making, in the absence of a tradition of political compromise, increasingly runs the risk of either inconsistency, or even deadlock.     

Analysis of AmpFlSTR MiniFiler™ loci and its forensic application

The allele frequencies of eight MiniFiler™ loci have been analyzed in 101 Japanese individuals living in Kanagawa with informed consent by means of ABI 310 Genetic Analyzer. A total of 7 alleles for D13S317, 8 alleles for D7S820, 11 alleles for D2S1338, 11 alleles for D21S11, 5 alleles for D16S539, 14 alleles for D18S51, 8 alleles for CSF1PO, and 13 alleles for FGA were observed. The polymorphic profiles of these MiniFiler™ loci in the present study were essentially the same as those obtained by using the AmpFlSTR^® Identifiler^® PCR Amplification kit. The combined matching probability of eight MiniFiler™ loci and cumulative probability of paternity exclusion were estimated as 1.97 × 10⁻¹⁰ and 0.9996, respectively. The MiniFiler™ kit was useful for individual identification in forensic analysis.     

Case report: Etizolam and its major metabolites in two unnatural death cases

A simultaneous analytical method for etizolam and its main metabolites (alpha-hydroxyetizolam and 8-hydroxyetizolam) in whole blood was developed using solid-phase extraction, TMS derivatization and ion trap gas chromatography tandem mass spectrometry (GC-MS/MS). Separation of etizolam, TMS derivatives of alpha-hydroxyetizolam and 8-hydroxyetizolam and fludiazepam as internal standard was performed within about 17 min. The inter-day precision evaluated at the concentration of 50 ng/mL etizolam, alpha-hydroxyetizolam and 8-hydroxyetizolam was evaluated 8.6, 6.4 and 8.0% respectively. Linearity occurred over the range in 5-50 ng/mL. This method is satisfactory for clinical and forensic purposes. This method was applied to two unnatural death cases suspected to involve etizolam. Etizolam and its two metabolites were detected in these cases.     

Amplification of a variable number of tandem repeats (VNTR) locus (pMCT118) by the polymerase chain reaction (PCR) and its application to forensic science

A genetic locus (D1S58, defined by DNA probe pMCT118) that contains a variable number of tandem repeats (VNTR) has been successfully amplified from a very small amount of genomic deoxyribonucleic acid (DNA) by the polymerase chain reaction (PCR). The DNA sequence of the locus was determined and was found to consist of a 16-base consensus sequence and flanking sequences. Oligonucleotide primers complementary to the flanking sequences were synthesized to serve as primers for amplification of MCT118 by the PCR method. Human genomic DNA isolated from blood (2 ng from each sample) was successfully amplified at the MCT118 locus, and polymorphic bands were detectable by ethidium bromide staining after electrophoresis on polyacrylamide gels. Determination of genotypes at this VNTR locus can now be routinely achieved within 24 h, without the need for Southern blots or radioactive materials. Furthermore, the small size (387 to 723 base pairs) of the DNA fragments produced in the PCR amplification permits good resolution of individual alleles that differ by only one repeat unit. The precise specification of the number of tandem repeats present in each allelic fragment is reproducible from one analysis to another.     

Traumatic rupture of the basilar artery: report of two cases and review of the literature

Two cases of traumatic rupture of the basilar artery are reported. In the first case, severe basal subarachnoid hemorrhage (SAH) due to a complete transverse tear of the basilar artery was observed in a 53-year-old restrained male driver who was involved in a head-on collision while intoxicated and drowsy. He lost consciousness shortly after the accident and was admitted to hospital in cardiopulmonary arrest. Intensive resuscitative therapies produced cardiac response, but he died 50 minutes after the accident. The ethanol concentration in his blood and urine was 0.35 and 0.55 mg/ml, respectively. In the second case, SAH due to a similar tear of the basilar artery was observed in a 47-year-old man who received several fist blows to the face while intoxicated. He suddenly lost consciousness after the final blow and was admitted to hospital in cardiopulmonary arrest. Intensive resuscitative therapies produced cardiac response, but he died 6 hours after the event. In these cases, the mechanism of the traumatic rupture of the basilar artery is thought to be overstretching due to hyperextension of the head, and intoxication, drowsiness, or both may have interfered with the decedents' ability to protect themselves; thus, the hyperextension of the head may have been rather forceful.     

The provision of public services by government funded decentralized agencies

Public services are often provided by lower level agencies that are funded by higher level government. Since markets for such services do not exist, normal pressures to minimize costs do not operate; indeed, usually these costs are unobservable. We study a principal-agent model which emphasizes the distinction between the financing and provision of public services. Two broad situations are analyzed: (i) the agencies are induced to reveal true costs; and (ii) in addition, to minimize costs, agencies must be induced to exert effort. The characteristics of the optimal funding contract and the marginal cost of public funds are derived in each case.     

Genetic polymorphism of human C1R subcomponent of the first complement component in the Japanese population

Genetic polymorphism of the C1R subcomponent of human complement component C1 has been investigated in neuraminidase treated EDTA plasma samples of 440 healthy Japanese individuals living in Tokyo by means of thin-layer polyacrylamide gel isoelectric focusing (PAGIEF) at pH 3.5-9.5 in the presence of 8.0 M urea followed by an electroblotting with enzyme immunoassay. Three common and three rare alleles were detected in the Japanese population. Of these, two common alleles were identical to C1R*1 and C1R*2 and other new alleles were tentatively designated C1R*3, C1R*4, C1R*5 and C1R*6, respectively. The results of the family studies suggested that the genetic model for C1R polymorphism assumed autosomal codominant Mendelian inheritance. The allele frequencies were estimated as C1R*1 = 0.4216, C1R*2 = 0.3602, C1R*3 = 0.2068, C1R*4 = 0.0091 and C1R*R(C1R*5 and C1R*6) = 0.0023, respectively. The distribution of allotypes fitted the Hardy-Weinberg equilibrium. The C1R system provides a useful genetic marker for human genetics, anthropologic studies and forensic science.     

Molecular analysis of the human esterase D gene ESD(*)Q0(yonago) responsible for incompatibility in a Japanese paternity case

In a Japanese paternity test, an alleged father was excluded only by reverse homozygosity of esterase D (ESD) phenotypes (mother, ESD 1; child, ESD 1; alleged father, ESD 2) out of 43 classical and DNA markers investigated. To solve the aberrant inheritance of the ESD phenotypes observed between them, fragments for all eight coding exons amplified by polymerase chain reaction (PCR) were subjected to DNA analysis. The child and alleged father shared a null allele, originating from ESD(*)1. It was characterized by having TGA for the stop codon instead of TCA for serine at codon 63. Thus, the sharing of a rare null gene, ESD(*)Q0(yonago), increased the probability of paternity.     

Anomalous origin of the right coronary artery from the left sinus of Valsalva: report of two cases.

Anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva (LSV) is rare and has only recently been recognized as a cause of sudden cardiac death in otherwise healthy individuals. In this report, we describe two cases of anomalous origin of the RCA from the LSV. In the first case, a previously healthy 11-year-old girl died suddenly and unexpectedly. An autopsy revealed no abnormalities, except for anomalous origin of the RCA from the LSV. In the second case, a 21-year-old woman died by drowning in a bath, probably after an episode of syncope brought about by anomalous origin of the RCA from the LSV.
