Application of Volume‐of‐Fluid Method to Analyze the Viscosity Effect on the Spine Formation of Bloodstains

In bloodstain pattern analysis, the blood droplet volume and surface impact velocity play an important role, and many related experimental studies have been carried out. If an appropriate computational fluid dynamics (CFD) model that could solve bloodstain patterns, especially spine formation bloodstain patterns, can be obtained, the blood droplet volume and impact speeds at various crime scenes can be predicted more accurately. For this purpose, Flow‐3D software using the volume‐of‐fluid method was applied to analyze the behavior of human blood droplets during an impact event, especially focusing on the viscous effect on splashing, which forms the spine which can be used to predict the impact velocity. To obtain a non‐Newtonian viscosity model of blood for a computational fluid dynamic analysis, the venous blood samples of 163 people were tested using a hemorheology instrument. Among the venous blood samples of 163 people, 37 samples for which all blood test results were in a normal range were selected for the non‐Newtonian viscosity modeling. From the CFD analysis, it could be concluded that a non‐Newtonian viscosity model is more appropriate than a constant viscosity model for predicting splashing that forms the spine. The gradient of the non‐Newtonian model at a high shear rate has more of an effect on spine formation than that at a low shear rate. The lowest viscosity with a high velocity at the outer front of the radiating flow plays an important role in forming the splashing pattern.     

Single Outcome Agreements and Partnership Working in Scottish Local Government – Year One

Single Outcome Agreements (SOAs) are a mechanism that it is argued will deliver key national and local priorities based on a new relationship between central and local government in Scotland. SOAs are to be developed and implemented through partnership working exercised by Community Planning Partnerships (CPPs). A survey of the first (2008) SOA participants from local authorities and their Community Planning partners was conducted in 2008, with a particular focus on the interrelationships between the 2008 SOA development process and partnership working at the local level. Findings of this study suggest that there was a positive link between the strength of existing CPPs and partner engagement in the 2008 SOA development. However, partner engagement in the 2008 SOA development process did not affect survey respondents' confidence that the ongoing SOA development and implementation will strengthen partnership working in the long -term. This study also suggests that in addition to the practical difficulties such as limited time and staff resources, mistrust between local partners, and local players' scepticism about the central government's intention to free up local government may be barriers to the success of the SOA. Overall, respondents in this study showed realistic but hopeful attitudes to what the SOA was about and what could be achieved through it over time. The information gathered through this study should be merited as baseline data which captured the SOA participants' early experience and expectations.     

A Comparative Institutional Analysis of Korean and Japanese Clientelism

Clientele networks are differently structured across nations, depending on the political institutional setup and the configuration of political and social forces. The political institutional setup, which is cross-nationally different, determines where clientele networks are formed, how extensive they are and how long they can persist. The configuration of political and social forces, which varies over time, defines who takes the lead in clientele networks and how effective they are for producing policy effects. A comparison of Korean and Japanese clientelism suggests that the Korean case represents a form of national-level, defensive, non-cumulative and high political-risk clientelism, while the Japanese case illustrates a form of local-level, cumulative and low political-risk clientelism. Korean clientelism is not a copy of the Japanese variant. Based on this analysis, the author suggests that not every social organisation is functional for democratic governance. He also points out that the gradual process of disintegrating clientele networks is on the move.     

Group size does matter: differences among sexual assaults committed by lone,double, and groups of three or more perpetrators

ABSTRACT

We compared a total of 340 sexual assault cases based on offender characteristics, victim characteristics, and offence behaviours to identify differences among sexual assaults committed by lone, double, and groups of three or more perpetrators in South Korea. Several differences were found among sexual assaults committed by varying numbers of offenders. First, lone, double, and groups of three or more perpetrators differed with respect to age, marital status, and employment status. Second, substantial differences in victim characteristics were observed with respect to age and the victim–offender (v–o) relationship. Third, significant differences in offence behaviours, including offence type, planning, method of approach, knife possession, and stealing property, were found. Furthermore, we identified several variables that significantly predict group size using logistic regression analyses. The study has theoretical implications for understanding how group dynamics influence the behaviours of rape perpetrators, and practical implications for victim treatment and offender intervention.     

The tax-welfare mix: explaining Japan's weak extractive capacity

Abstract

Despite having the highest level of public debt in the Organisation for Economic Co-operation and Development (OECD), higher than Greece or Italy, Japan has one of the lowest aggregate tax burdens of the advanced industrial democracies. This paper asks why Japan, once described as a strong developmental state, has had such a weak extractive capacity, an inability to raise revenues to confront deficits and public debt? In contrast to the existing explanations that focus on political institutions, partisan preferences, or economic globalization, this article argues that Japan's ‘tax–welfare mix’ – the combination of taxes and redistributive welfare polices – undermined the state's long-term capacity to secure adequate tax revenue. More than just a source of revenue, taxes can be used directly to achieve redistributive goals, such as targeting low taxes and exemptions to specific groups. This study shows how Japan's tax–welfare mix diminished its extractive capacity through three mechanisms: the political lock-in of a redistributive social bargain struck around low taxes, the timing and sequencing of its tax policy and welfare development, and the erosion of public trust, which undermined tax consent. Beyond offering a new theory of extractive capacity, the tax–welfare mix explains aspects of Japan's tax structure that defy existing explanations and contributes to our understanding of the capitalist development state by highlighting the redistributive political function of tax policy and its long-term impact on state capacity.     

Nationalism,Confucianism, work ethic and industrialization in South Korea

The “economic miracle” of South Korea has been well documented by many scholars, but most studies have focused on the cooperative relations between the state and entrepreneurial elites, with little attention being given to the accomplishments and contribution of Korean labor to industrial development. To date there has been no comprehensive sociological study as to how workers in South Korea were “ideologically” mobilized and motivated to commit their labor power to the process of industrialization. In an attempt to redress this imbalance, this article offers an analysis of the role of Confucianism and nationalism in the state-sponsored ideology of work in South Korea during its economic boom of the 1960s and 1970s. It is argued here that both the workers' voluntary participation in industrial work and the harmony in the workplace, which were two of the most essential factors in the nation's remarkable economic success during the 1960s and 1970s, were intimately linked to a new ideology of work and entrepreneurship which combined nationalism and pro-growth Confucian precepts. The article will thus sociologically examine ways in which ideas about work in South Korea have incorporated nationalist ideals and Confucianism, and analyze the relevance of this ideology of work to the nation's phenomenal economic growth.     

Political suicide among Korean youth

Abstract

A striking aspect of the South Korean political protest movement of the 1970s, 1980s, and early 1990s was the frequent self-immolation of young Korean activists. This trend toward political suicide—politically motivated voluntary death—began with the laborer Chun Tae-il's suicide in 1970 and increased dramatically in the late 1980s and early 1990s. It is estimated that in the 1980s alone nearly one hundred young Koreans put an end to their lives as a form of antigovernment protest! This article explores why so many young people in Korea have chosen to take their own lives in this way.     

Relation of Kinetic Energy to Contact Wounds of the Head by Centerfire Rifles and Shotgun Slugs

Wounds of high‐energy centerfire rifles and shotguns represent distinctive injuries of forensic importance. Previous studies of contact wounds have shown variability in the potential of these weapons to produce bursting wounds of the head. The present study analyzed contact head wounds owing to 26 centerfire rifles and nine shotgun slugs and compared them with respect to weapon, ammunition, entry wound site, and projectile kinetic energy. The bursting effect, defined for this study as disruption of at least 50% of the head, occurred in 25/35 of cases and was related to kinetic energy. Bursting was associated with energies <2700 ft‐lbs in 12/22 cases and energies >2700 ft‐lbs in 13/13 cases. The volume of gunpowder gas injected into the wound was considered as contributing to the bursting phenomenon. There was no relation of bursting to the specific entrance wound site, type of ammunition, or projectile fragmentation.     

A Ferris Wheel Accident at a Movable Amusement Park

This study presented a Ferris wheel accident case. A Ferris wheel is composed of many parts, and the outmost ring of it is assembled using a lock pin. This accident occurred because the lock pin caught the door of a gondola and the gondola overturned. Five of the seven passengers in the gondola fell to the ground, along with the gondola's viewing window. The investigation revealed that the gondola became stuck when its door was caught by a lock pin at the Ferris wheel's three o'clock position. The contact between the door and the lock pin was due to a structural problem: There was not enough space allotted between the door and the lock pin. Therefore, if a passenger pushed on the gondola's door, the potential existed for contact between the door and the lock pin.     

Population data of nine miniSTR loci in Koreans

For highly degraded DNA samples of forensic casework, new miniSTR systems have been developed to supplement the current STR systems. In the present study, nine miniSTR loci were analyzed in 300 unrelated Koreans using three multiplex PCR systems (multiplex I: D10S1248, D14S1434 and D22S1045; multiplex II: D1S1677, D2S441 and D4S2364; and multiplex III: D3S3053, D6S474 and D20S482), and allele frequencies and forensic parameters were calculated. These data demonstrated that D10S1248, D2S441, D22S1045, D14S1434, and D6S474 are as highly informative as the CODIS STRs suggesting that the miniSTRs could be useful for forensic analysis of degraded DNA.
