This study examined whether game usage would alleviate players' aggressive tendencies. Other game-related variables, psychological care factors (adaptive game use tendency, game self-efficacy, and life self-efficacy), and psychological problem factors (loneliness and depression) were controlled for determination of the effect. We drew on the catharsis theory from therapeutic psychology literature to explain how game usage contributes to the alleviation of aggressive tendencies. Over two weeks data were collected from 918 participants online. The results indicated that gaming activity had a significant effect on aggression. Higher levels of game and life self-efficacy, as well as adaptive game use tendencies, decreased the degree of aggression. Likewise, higher levels of loneliness and depression reduced the degree of aggression. Results and implications are discussed.

In order to investigate territorial behaviour, Pungitius sinensis kaibarae were collected from Sacheon-river, Kangwon-do, Korea. They are reared in aquarium with designed experimental region from March to May 1996. In this study, territorial behaviour was divided into 1) pre-territorial movements of a shoal under varying water-weeds position 2) individual ranking patterns in connection with total length of fish 3) the change in size of territorial maps during the parental stage. The movements of a shoal tend to prefer regions with water-weeds and the lower half of the aquarium. Competition for territory was fierce, and fish that are longer in total length dominate smaller one in occupying territory. Both males and females developed territorial behaviour as they grew. However, male's territory was enlarged according to the hatching and dispersion of fry. At this time, aggressive tendencies reached their peak.

Adenoid cystic carcinoma is a distinctive neoplasm of the salivary gland and is the most common malignant tumor of submandibular gland. Although adenoid cystic carcinoma grows slowly, it shows aggressive tendencies with the ability to invade peripheral nerves. This ability enables an adenoid cystic carcinoma to extend along the nerves and spread long distances, resulting in high incidence of distant metastasis and recurrence. Therefore, radical resection is the treatment of choice for this carcinoma. We performed partial mandibulectomy, neck dissection and immediate reconstruction using a radial forearm free flap on a 54 year-old man with adenoid cystic carcinoma on the right submandibular gland. And as an adjunctive therapy, chemotherapy with cisplatin and 5-fluorouracil was used. We report our case along with a literature review.

Corrosion is of greatest concern for metallic materials exposed to corrosive seawater or aggressive marine atmospheres. Marine structures and components made of metallic materials incur an initial cost and additional large costs for corrosion control and maintenance. There have been worldwide efforts to minimize marine corrosion and extend service life of the materials. It is believed that various factors are associated with corrosion of marine grade metallic materials, particularly the temperature of the solution affecting the corrosion rate by changing dissolved oxygen solubility and concentrations of chloride. In the present study, the electrochemical characteristics of S355ML steel are investigated to identify corrosion acceleration tendencies with changes in solution temperature under marine environments. It was found that increasing seawater temperature, promoted not only activation of chloride ion transfer, but also the formation of porous $Fe(OH)_3$ or $Fe_2O_3$, leading to the acceleration of corrosion.

This paper examined gender differences in a rate, type, relevant variables of delinquent behavior, and a gender differences regarding the relative influence of family, personality, academic achievement, sexual abuse and alcohol .drug abuse on delinquent behavior among Korean adolescents. Method: Data were collected by self-report questionnaires. Subjects consisted of 2,100 adolescents (male 1,396, female 704) in Korea, using proportional stratified random sampling method. Statistical methods were Chi-square, t-test and path analysis. Result: Male adolescents had higher rate of delinquent behavior, and more all types of delinquent behavior (antisocial, aggressive, and psychopathic) than female. Male adolescents showed more dysfunctional family dynamic environments, higher antisocial personality and sociability than female adolescents. Female adolescents had higher depressive tendencies than male. The most powerful contributing variables on male delinquent behavior were age, antisocial personality, parent-child relationship, isolation feelings, and sexual abuse in this order named. Drug abuse, isolation feelings, antisocial personality and parent-child relationship tended to be contributing variables for female delinquent behaviors in this order named. Conclusion: This investigation will provides a foundation for theory that addresses the complexities of both gender-specific and gender influences on delinquent behavior and development of preventive strategies for female delinquency.

The significance of this study lies in the fact that it looks into the function of games as one of the important leisure activities at the moment when negative perception on overall game industry is becoming an obstacle in settlement of sound game culture. Game is one of the activities enjoyed in leisure time. The main positive effects of game were analyzed classifying them into 10 types including the stress relief and alleviation of tension, diverse identity experience and positive socialization experience, strengthening of self-respect and ideal self-realization, strengthening of independent thinking and problem-solving capacity, motivation for learning, enhancement in physical capacity, decrease in aggressive tendencies, cultivation of awareness on equality, increase in familiarity with the civilization of technology, and strengthening of individuality based on diversity.

Financial Accounting Standards Board (FASB) Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes: An interpretation of FASB Statement No. 109, requires firms to evaluate uncertain tax positions and disclose information on their liabilities for these positions, unrecognized tax benefits (UTBs). We analyze the FIN 48 disclosures for calendar-year-end Korean companies listed on NYSE and NASDAQ and examine the Korean firms' tax aggressiveness utilizing the UTBs. The results suggest that stock exchange and firm size do not play a role in the Korean firms' tax aggressiveness, contrary to the matched U.S. firms and that the Korean firm in the miscellaneous retail industry is more tax aggressive than the firms in the communications, depository institutions and business services. In addition, we find evidence that the Korean firms are less tax aggressive than the matched U.S. firms. We also examine the Korean firms' tax avoidance tendencies using other measures of avoidance, leading to mixed results. Finally, we examine the association between the UTBs and other measures of tax avoidance and find a significant and negative association between the UTBs and the long-run cash effective tax rate.

To ensure safer road conditions, understanding the human factors influencing driving behavior is crucial. However, there are many difficulties in deriving the characteristics of individual human factors that affect actual driving behaviors. Therefore, this study analyzes self-reported dangerous-driving propensities in order to explore potential correlations with drivers' behaviors. The goal is to propose a method for assessing driving tendencies based on varying traffic scenarios. The study employed a questionnaire to gauge participants' propensity to drive dangerously, utilizing a simulator to analyze their driving behaviors. The aim is to determine any notable connections between dangerous-driving propensity and specific driving behaviors. Results indicate that individuals exhibiting a high propensity for reckless driving, as identified by the Korean DBQ, tend to drive at higher speeds and display more aggressive acceleration patterns. These findings contribute to a potential method for assessing reckless driving drivers.
