This study is to examine the impact of spatial characteristics of cities on homicide based on spatial econometric model. It selects housing types, racial heterogeneity, residential instability, overcrowding, commercial area, rate of 15 to 29 ages, and rate of the elderly as variables for spatial characteristics of cities. This study employs spatial regression analysis applying the spatial error model to analyze the data from 229 locals collected from Korean Statistical Information Service and Statistical Year Book of local governments. As a result, it shows that homicide has close relationships with apartment and multi-housing as housing types, racial heterogeneity, residential instability, and overcrowding, but not with the commercial area, rate of 15 to 29 ages, and rate of the elderly. The study contributes to expanding understanding and explanation on the causes of homicide focusing on social-structure approach for criminology by analyzing a more advanced model in applying variables than one of existing literature. This study suggests follow-up research on homicide based on both social-behavior approach and social-structure approach in the near future for the development of criminological theory.

Purpose: The purpose of this study is to examine the new drugs that recently have shown rapid increase and provide solutions to eradicate them. Method: This study used the relevant preceding studies, statistics, and overseas materials to identify the new drug problems and suggest solutions. Result: Compared to the past, the numbers of criminals detected for the administration, distribution, and production of drugs are rapidly increasing. According to the statistical data on drugs in 2021, the number of drug-related cases decreased compared to the previous year. However, there are concerns because the amount of detected drugs increased more than three times, and the age group of drugrelated criminals are getting younger. Such results are largely affected by the spread of new drugs. In particular, it is deemed to be affected by the spread of new drugs, such as fentanyl, yaba, khat, kratom, etc., as well as the new psychoactive drugs and hemp-related materials. Conclusion: In response to spread of new drugs, this study suggests simplifying the temporary classification of drugs, enforcing control of foreign drug users, strengthening the cooperation with relevant institutions, such as Korea Customs Service and the Ministry of Food and Drug Safety, and intensifying the punishment on the drug users in order to strengthen the countermeasure against the new drugs.

Speaker verification is becoming popular as a method of non-face-to-face identity authentication. It involves determining whether two voice data belong to the same speaker. In cases where the criminal's voice remains at the crime scene, it is vital to establish a speaker verification system that can accurately compare the two voice evidence. In this study, to achieve this, a new speaker verification system was built using a deep learning model for Korean language. High-dimensional voice data with a high variability like background noise made it necessary to use deep learning-based methods for speaker matching. To construct the matching algorithm, the ECAPA-TDNN model, known as the most famous deep learning system for speaker verification, was selected. A large dataset of the voice data, Voxceleb, collected from people of various nationalities without Korean. To study the appropriate form of datasets necessary for learning the Korean language, experiments were carried out to find out how Korean voice data affects the matching performance. The results showed that when comparing models learned only with Voxceleb and models learned with datasets combining Voxceleb and Korean datasets to maximize language and speaker diversity, the performance of learning data, including Korean, is improved for all test sets.

The court in Korea values evidence justice, and also demands justification for the process of collecting evidence. Therefore, it is necessary to raise the level of organizational commitment, which means that the police investigators performing these tasks feel attached to the police organization they belong to, and that they feel united about the goals of the organization. Based on this recognition, the study analyzed the effects of the police's perception of organizational Justice on organizational commitment, and classified organizational Justice into distributive Justice, procedure Justice and interaction Justice. Therefore, this study analyzes the effect of the police's perception of organizational Justice on organizational commitment and verifies the effect through multiple regression analysis by injecting the trust of Supervisors into a mediating variable. The study was also conducted on the assumption that the trust of Supervisors is important in carrying out the field investigators work in the South Korean police. To achieve the purpose of this research, a total of three surveys were conducted from May 2017 to October 2019 at the National Police Agency using the selection process of investigators and job training courses for the national police, and a total of 500 copies were used as analysis data. Looking at the results analysis of this study, first, it was found that there was a statistically significant static (+) effect on organizational commitment, where the organizational Justice of police officers was a independent variable. Second, the relationship between organizational Justice and organizational commitment has shown that the trust of Supervisors has a mediating effect in korean police organization.

This study aims to understand the background and characteristics of receiving Hallyu based on the cognitions and attitudes toward Korea and Korean culture in the Philippines. With the background of Business Hallyu and Cultural Hallyu between the two countries, this study conducted the Focus Group Discussion(FGI) research, literature research and analyzed the statistical resources. The economic and cultural exchanges between Korea and the Philippines have been increased by the effect of Hallyu, but the socio-cultural conflicts, such as Kopino issue, crimes related to Koreans have been also grown. Thus, the Hallyu research focused on the Philippines is necessary, and it will be a cruical variable to forecast the socio-cultural relationship between Korea and the Philippines. The FGI research recruited participants in both undergraduates in the Phillippines and the Filippino migrants in Korea. The FGI participants of each group shows the differences of cognitions, attitudes, and actions to consume Hallyu, and the participants of both groups agrees that experiences of contacting Koreans influence on understanding Korea and its culture. The FGI participants have tried to watching Korean dramas, learning Korean languages, and building relationships with Koreans in order to adjust Korean culture. In order to improve the relations between Korea and the Philipines, Hallyu needs to promote its values as the unique culture and also universal culture in the world. Korea should increase understanding of the Filippino culture to overcome cultural differences and make efforts on localize the Hallyu 3.0 in the Phillippines.

Recently, Police integrity has been issued on the media, which cause discredit of police organization. Although high level of morality and integrity are required compared to other occupational groups due to their authority to exert legal force to the citizens and a variety of policies have been enforced by the National Police Agency for the purpose of uplifting the integrity of the officers, in reality, corruption had not yet been eradicated. At this point in time, this study attempted to draw implications for uplifting integrity by utilizing domestic and foreign preceding studies and statistical data related to police corruption and uplifting integrity. The inspection system through whistle-blowing was pointed out as a problem in the institutional framework that hinders uplifting integrity of the police officers and the perception in which police officers are regarded as potential criminals was also pointed out as a problem. Also, vague standards of disciplinary action in examining an offense of a police officer and lack of care for those who were disciplined in the past which affects loyalty to the organization were presented as problems. Based on such suggested concerns, policies for uplifting integrity and restoring citizens' trust in the policies officers were proposed. The proposed agenda were warning the police officers by presenting clear and specific category of corruptive behaviors, expressing the necessity of devising a system that prevents the officers from committing serious crimes by discovering problematic officers earlier through introduction of Early Warning System(EWS) of US and Australian police in order to break away from exposure-oriented inspection system, and reinforcing the testing of integrity in the new employment process.

The authenticity of a document is recognized only when sealing on the document can be recognized to be the same as the original seal of a person who drew up the document. But forge in various ways is prevalent; forge through stamp-copy, forge through photocopying, forge through computer seal sculpture machine, forge through photosensitive resin, etc. Among the methods above, a method of making a forged seal with photosensitive resin panels, which is one of the easiest forging methods, enables making a forged seal the same as the original seal through the work of projecting ultraviolet rays on a resin panel on which negative film is stuck after making it using the original seal. But as research into this reality has not been sufficiently carried on, it is difficult to identify forged sealing through photosensitive resin seals, indeed. For this reason, unless regulations about making forged seals using resin machine for print are enforced, crimes related to forged seals using photosensitive resin are expected to increase in the future. Thus, after stamping 10 resin seals made based on an original seal carved of thick and thin strokes of characters, this paper intends to clarify that there are differences between original sealing and forged sealing through sealing identification method. Consequently, we verified the significant difference in the statistics between original sealing and forged sealing.

A self-administered questionnaire survey and face-to-face interviews were conducted on 150 local residents belonging to seven villages, 160 visitors and 86 experts in order to analyze the attitudes of groups of local residents, visitors as well as experts toward the development plan of Sobaeksan Jarak-gil. Reliability analysis and one-way ANOVA were performed on the data collected by a questionnaire survey using IBM SPSS Statistics 20.0 after coding. The Duncan Test was conducted as a post-hoc test. Based on the analytical results, in economic terms, the expert group expected an increase in income, improvement in living standards and increase in expenditure for the maintenance of local infrastructure. In environmental terms, the visitor group was highly concerned about the disruption of the local natural environment and ecosystem, destruction of local properties and landscape, increase in water/soil/air pollution and increase in solid waste and noise. In social and cultural terms, the expert group had higher expectation for excavation of traditional cultural properties, instillation of local patriotism and pride, and the visitor group was highly concerned about a rise in crime, destruction of indigenous culture/increase in imitations, and induction of conflicts between residents. It is estimated that these results will be used as basic data for establishing the development plan of the mountainous ecological trail reflecting opinions of various groups.

This study was conducted to find out the difference in judgment of murder cases by participants' generation according to the type of murder. 196 adults in their 20s and older were randomly assigned to one of the scenarios of parricide, filicide, and murder, then responded to the judgment(ex. judgment of the perpetrator, degree of deviation from social norms, and judgment of victim responsibility). Finally, 128 responses were used in the analysis. As a result, it was found that the main effect of the murder type and the interaction effect of the generation and the murder type were not shown in all dependent variables. However, the difference between generations was statistically significant in the judgment of the perpetrator (e.g., perpetrator blame, perpetrator responsibility, intentional crime, etc.), indicating that millennials made unfavorable judgments to the perpetrator. Especially, in the case of parricide, it was found that millennials made unfavorable judgments to perpetrators than older generations. Also, it was found that the participants of the older generation tended to make unfavorable judgments toward the perpetrator of murder rather than the perpetrator of parricide. Finally, based on these results, this study proposed the need to reconsider the 'victim of survivors' factor, which is considered as a weighing of an offense for special sentencing factors.

We investigated the influences of positive thought about social capital on social participation of the elderly Koreans. The study design was cross-sectional analysis of the National Statistic Office Study of Korean Society Statistics Survey 2003. Participants were total of 8,586 representative samples. Two types of social participation were investigated: meeting attendance and volunteer obligations. The base model included five thoughts about social capital that must be settled as a priority in Korea, i.e., reducing the differences between the rich and the poor, reducing the crime rate, reducing regulations and corruption, improving the moral level, eliminating environmental pollution. Social participation was influenced by positive thoughts about social capital, and different kinds of thoughts had different influences on different types of social participation. The elderly who responded positively to 'reducing the differences between the rich and the poor' attended all two types of social participation more. Along with education and health status, positive thought about social capital is another important factor that influences increased social participation. It may also compensate for deteriorating health with increasing age by promoting social participation. Encouraging social participation is a good way to improve the health of the elderly, as are efforts to change thought about social capital positively.
