The connection of police strategies for coping with workplace problems to stress in two countries

This research examined the direct effects of coping strategies on stress and the moderating effects of coping strategies on the associations between workplace problems experienced by police and stress in South Korea and the United States. Data revealed that coping strategies did not change the strength of connections between workplace problems and stress. Especially in the United States, the use of escape as a coping strategy was related to high stress. Findings were most consistent with the use of organizational-level interventions to increase police officers' job control and advancement opportunities, and pointed to the need to consider support as a way to limit stress.     

Autosomal short tandem repeat analysis of ancient DNA by coupled use of mini- and conventional STR kits

Abstract: Multiplex autosomal short tandem repeat (STR) genotyping enables researchers to obtain genetic information from ancient human samples. In this study, we tested newly developed AmpF?STR^® MiniFiler? kit for autosomal STR analysis of ancient DNA (aDNA), using human femurs (n = 8) collected from medieval Korean tombs. After extracting aDNA from the bones, autosomal STR analyses were repeated for each sample using the AmpF?STR^® MiniFiler? and Identifiler? kits. Whereas only 21.87% of larger‐sized loci profiles could be obtained with the Identifiler? kit, 75% of the same loci profiles were determined by MiniFiler? kit analysis. This very successful amplification of large‐sized STR markers from highly degraded aDNA suggests that the MiniFiler? kit could be a useful complement to conventional STR kit analysis of ancient samples.     

Work-Family Conflict and Intimate Partner Violence in the South Korean Military: Mediating Role of Aggression and Buffering Effect of a Counseling Resource

The objective of the current study was to identify the relationship between work-family conflict (WFC) and intimate partner violence (IPV) among military personnel, and verify the mediating role of aggression and buffering effect of a counseling resource. A total of 293 married Korean Air Force personnel were surveyed using a self-administered questionnaire; their responses were analyzed with a structural equation model. The major findings were that 36.9 % of respondents have perpetrated IPV, the prevalence of verbal violence was 33.4 % and physical violence was 16.0 %. Aggression mediated the important part of the association between WFC and IPV. Also, presence of a counseling resource attenuated the relationship between WFC and aggression. The findings suggest that it is necessary for the military to build a personnel counseling system to prevent spouse abuse, develop professional counseling services, and accurately identify aggression tendencies among military personnel.     

Allele frequencies of 15 STR loci using AmpF/STR Identifiler kit in a Korean population

The genetic variations for 15 short tandem repeat (STR) loci D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA were performed on 231 unrelated Korean population using commercially available AmpF/STR Identifiler kit.     

Validity of Demirjian's and modified Demirjian's methods in age estimation for Korean juveniles and adolescents

In estimating age of juveniles and adolescents, the teeth are employed primarily because of its low variability and less affection by endocrine and nutritional status in development. Demirjian established criteria for evaluating maturity of teeth and his method has been used throughout the world. However, several studies showed the inappropriateness of Demirjian's method on populations other than the one it is based on. Consequently some researchers modified Demirjian's method using data of several different populations. Demirjian himself also published a revised method to overcome other shortcomings of his original method. The aim of this study was to test the validity of Demirjian's and the modified methods (Demirjian's revised, Willems', Chaillet's and new Korean methods) for Korean juveniles and adolescents. 1483 digital orthopantomograms which consist of 754 males and 729 females in the age range of 3-16 years were collected. New age estimation method based on Korean population data was calculated. Dental age was estimated according to each method and the validity was evaluated using the differences between chronological and dental age. The inter- and intra-observer reliability was evaluated to be excellent. Statistically significant difference was observed between chronological and dental age in all the methods for both sexes except new Korean method for both sexes and Demirjian's revised method for males. However, when analyzing absolute and squared value of difference, Willems' method was found to be most accurate followed by new Korean method with slight difference for Korean population for both sexes. In conclusion, both Willems' method and new Korean method conducted by present study were proven to be suitable for Korean population.     

Measuring the crime displacement and diffusion of benefit effects of open-street CCTV in South Korea

Crime prevention strategies are implemented to reduce the damage caused by crimes with CCTV (Closed-Circuit Television) being broadly accepted as one of the main strategies. However, along with CCTV's perceived high expectations as crime deterrent, there is also a growing controversy over CCTV's potentially unexpected limitations. For example, the crime displacement (the presence of CCTV will change the locations of crime and its total number will not change) and the diffusion effects of crime control benefits (the crime prevention effect of CCTV may filter through to neighboring areas) are the representative controversial issues. In this study, we aimed to verify the crime displacement and the diffusion of benefit of open-street CCTV by analyzing the crime tendencies empirically.Gwang Myeong City in Gyeonggi Province, South Korea was chosen to analyze the crime displacement using the WDQ (Weighted Displacement Quotient) which compares the crime tendency of a location with that of its neighboring areas. The results showed that the crime prevention effect of the CCTV was significant. The number of robberies and thefts in the areas with CCTV installed reduced by 47.4%, while the areas without CCTV showed practically no change in the number of crimes. The crime displacement caused by the CCTV was not either found or inconsequential, and the crime rates in the neighboring areas also decreased slightly. Of major cause for concern was the fact that CCTV was marginally effective in deterring violence and as such, there should be a more detailed scientific analysis of the pattern and type of crimes committed in an area where CCTV's are being installed.     

The Impact of Management Capacity on Government Innovation in Korea: An Empirical Study

ABSTRACT

A common assertion within public management is that management capacity drives policy outcomes. This study tests that argument, focusing on an important policy outcome—innovation. Data were drawn from the Korean government to examine the impact of government's management capacity for the adoption and implementation of innovation. The results confirm that both managerial behaviors and structures are drivers of government innovation. The adoption and implementation of innovative projects require full-scale management capacity, encompassing innovative leadership, a quality workforce, appropriate structures/systems, and the ability to manage external influences. These results suggest that public management capacity drives innovation in government by changing managerial behaviors and structures. Implications of these results for managing government innovation are discussed.
