  • This study examined the effects of short and long term playing of video gamer on children's visual parallel processing. All of the 64 fourth grade subjects were above average in IQ. They were classified into high and low video game users. Instruments were a visual parallel processing task consisting of imagery integration items, computers, and the arcade video game, Pac-Man. Subjects were pre-tested with a visual parallel processing task. After one week, the experimental group played video games for 15 minutes, but the control group didn't play. Immediately following this, all children were post-tested by the same task used on the pretest. The data was analyzed by ANCOVA and repeated measures ANOVA. The results showed that relaying short-term video games improved visual parallel processing and that long term experience with video games also affected visual parallel processing. there were no differences between high and low users in visual parallel processing after playing short term video games.

  • This study analyzes the effect of the capital structure of Korean manufacturing firms on default risk based on Moody's KMV option pricing model where the probability of default is obtained by measuring the distance to default as a covariant in logit model developed by Merton (1974). Based on the panel data of manufacturing firms, this study achieves its primary objective, using a fixed effect regression model and examines the effect of a firm's capital structure on default risk amongst publicly listed firms on Korea exchange during 2005-2016. Empirical results obtained suggest that the rise in short-term debt to assets leads to increase the risk of default whereas the increase in long-term debt to assets leads to decrease the default risk. The benefits of short-term debt financing over a short-term period fade out in the presence of information asymmetry. However, long-term debt financing overcomes the information asymmetry and enjoys the paybacks of tax advantage associated with long-term debt. Additionally, size, tangibility and interest coverage ratio are also the important determinants of default risk. Findings support the trade-off theory of capital structure and recommend the optimal use of long-term debt in a firm's capital structure.

  • Using the Standard Precipitation Index (SPI), this study analyzed the drought characteristics of ten weather stations in Gyeongbuk, South Korea, that precipitation data over a period of 30 years. For the number of months that had a SPI of -1.0 or less, the drought occurrence index was calculated and a maximum shortage months, resilience and vulnerability in each weather station were analyzed. According to the analysis, in terms of vulnerability, the weather stations with acute short-term drought were Andong, Bonghwa, Moongyeong, and Gumi. The weather stations with acute medium-term drought were Daegu and Uljin. Finally the weather stations with acute long-term drought were Pohang, Youngdeok, and Youngju. In terms of severe drought frequency, the stations with relatively high frequency of mid-term droughts were Andong, Bonghwa, Daegu, Uiseong, Uljin, and Youngju. Gumi station had high frequency of short-term droughts. Pohang station had severe short-term ad long-term droughts. Youngdeok had severe droughts during all the terms. Based on the analysis results, it is inferred that the size of the drought should be evaluated depending on how serious vulnerability, resilience, and drought index are. Through proper evaluation of drought, it is possible to take systematic measures for the duration of the drought.

  • Purpose - In terms of human resource management, many Korean enterprises in China have experienced problems such as frequent resignations of Chinese employees and labor disputes. This can be mainly attributed to the fact that Chinese employees are not consistent with Korean vertical management methods, which is closely related to the national culture theory proposed by Hofstede, specifically the dimension of power distance and long- versus short-term orientation (LTO). Therefore, this research aims to investigate cultural differences between Korea and China from these two dimensions, and the impact on the human resource management of Korean-invested enterprises in China. Design/methodology - This research first utilizes the latest data (Wave 7) of the World Values Survey (WVS) to verify the difference in power distance and long- versus short-term orientation between Korean and Chinese cultures using responses from Korea and China, and then uses case analysis to analyze the impact of this cultural difference on the human resource management of Korean enterprises in China. Findings - Our main findings can be summarized as follows. Korea and China have significant differences in power distance and long- versus short-term orientation. In terms of power distance, Korean respondents show higher power distance compared to Chinese respondents. In the dimension of long- versus short-term orientation, it was found that Chinese respondents showed a shorter-term orientation, whereas Korean respondents showed a longer-term orientation. Originality/value - Previous studies put focus on the power distance and individualism-collectivism dimensions to explain cultural differences between Korea and China, and generated contradictory results. This research further confirms the cultural differences between Korea and China from the dimensions of power distance and long-versus short-term orientation using secondary data. The comparative studies from this perspective have long been underexplored and lack empirical confirmation.

  • Purpose: This study was done to evaluate the effects of a short-term life review on spiritual well-being, depression, and anxiety in patients with terminal cancer. Methods: The study used a pre posttest quasi experimental design with a nonequivalent control group. Measurement instruments included the Functional Assessment of Chronic Illness Therapy-Spiritual scale (FACIT-Sp12) and the Hospital Anxiety and Depression Scale (HADS). Participants were 32 patients with terminal cancer who were receiving chemotherapy or palliative care at hospitals or at home. Eighteen patients were assigned to the experimental group and 14 to the control group. A sixty minute short-term life review session was held twice a week as the intervention with the experimental group. Results: There was a statistically significant increase in spiritual well-being in the experimental group compared to the control group. There were also significant decreases in depression and anxiety in the experimental group compared to the control group. Conclusion: The results indicate that a short-term life review can be used as a nursing intervention for enhancing the spiritual well-being of patients with terminal cancer.

  • Background: The purpose is to investigate the immediate effects of kinesio taping on quadriceps induced fatigue by short-term squat. Methods: This research is cross-over designed study and conducted as a single-blind. Eleven students (Age: $18.91{\pm}0.49yrs$, height: $167.09{\pm}8.46cm$, $62.55{\pm}11.32kg$) were participated in this study. All the participants were applied short-term squat for inducing fatigue, and then intervented all three conditions (kinesio taping applied condition, placebo taping applied condition, non-taping applied condition). The interval of each intervention was at least a seven days to prevent carry-over effects. The participants were tested peak torque (isometric contracture) and active joint position sense (active JPS) pre-post intervention. A paired t-test was used to find the significance of pre-post intervention results and one-way ANOVA was used to find the significance between interventions with significant level as .05. Results: Peak torque was significantly increased on KT condition (p<.05). But there were no significant effects on active JPS. Because kinesio taping facilitates Ia afferent by tactile stimulation with stretched skin, reduced muscle power by short term squat which induce muscle fatigue was increased. But kinesio taping does not affect mechanoreceptor in muscles, induced active JPS by short-term squat had no changes.
