The purpose of this study was to investigate the relationship of time pressure, discretionary time, and subjective well-being(SWB) of university students. In order to achieve it, 493 university students(220 male, 232 female) completed a set of questionnaires about time pressure, discretionary time, subjective well-being. The t-test, multiple regression analysis were performed to analyze the data. The results are as follows. First, There were significant differences among the positive emotion, the negative emotion and time pressure. However, there was no statistically significant difference between the satisfaction of life and discretionary time according to gender. Second, time pressure was negatively correlated with the satisfaction of life of university students but positively correlated with the negative emotion. The discretionary time was positively correlated with the satisfaction of life of university students but negatively correlated with the negative emotion. Time pressure and discretionary time were not correlated with the positive emotion. Finally time pressure significantly correlated with the satisfaction of life, the negative emotion. And It seems that time pressure had an especially strong effect on the negative emotion. Such results imply that time pressure is important for reducing university students's the negative emotion, a subfactor of subjective wellbeing.

In this study, TiC/steel metal matrix composites were fabricated by powder metallurgy process using Fealloy powders with 3 wt.% Cr and 10 wt.% Cr, respectively, as matrix material. Subsequently, the composite samples were heat treated by the annealing and quenching-tempering(Q-T), respectively, to understand the effect of heat treatment on the mechanical properties of the composites. The correlation between microstructure and structural strength depending on the chromium content and the heat treatment conditions was studied through tensile, compressive, and transverse rupture test and microstructural analysis. In the case of TiC/steel composite containing 10 wt.% Cr, the tensile strength and transverse rupture strength at room temperature were significantly lowered by the influence of coarse chromium carbide formed at the TiC/steel interface. On the other hand, both TiC/steel composites containing 3 wt.% Cr and 10 wt.% Cr showed much higher compressive strength of about 4 GP after quenching-tempering compared to the annealed specimens regardless of the presence of the chromium carbide.

Objectives : The purpose of this study is to investigate the characteristics of the perception of the somatic symptoms and the cognitive emotion regulation strategies in patients with posttraumatic stress disorder (PTSD). Methods : A total of 48 patients meeting DSM-5 criteria for PTSD and 48 normal controls were recruited for participation in this study. We evaluated subjects using Clinician-Administered PTSD Scale (CAPS), Somato-Sensory Amplification Scale (SSAS), Hamilton Anxiety Scale (HAM-A) and Cognitive Emotion Regulation Questionnaire (CERQ). We analyzed data using an independent t-test and Pearson's correlation analysis. Results : In terms of SSAS, PTSD patients presented higher average SSAS scores than normal controls but the result is not statistically significant. In PTSD patients, the severity of PTSD is significantly correlated with CERQ-rumination and CERQ-catastrophizing. The SSAS scores of PTSD patients show the significant positive correlation with PTSD hyperarousal symptoms, CERQ-catastrophizing and CERQ-blaming others. Conclusions : These results reveal that patients with PTSD have maladaptive cognitive emotion regulation strategies such as rumination and catastrophizing. Somato-sensory amplification seems to be related with PTSD hyperarousal, CERQ-catastrophizing and CERQ-blaming others. Therefore, reducing somato-sensory amplification, rumination and catastrophizing can be helpful to reduce PTSD symptoms and somatic symptoms in PTSD patients.

The major purpose of this study is to see the effects of medical students' self-regulated learning on career adaptability. Therefore, we carried out self-regulated learning and career adaptability tests for the 252 medical students belong to the K university to examine the above subject. Then the respondents were divided into two groups according to the level of career adaptability to see the group differences on self-regulated learning. The results of this research are as follows. The group of high career adaptability was scored higher than the lower scored group in every domains of self-regulated learning except test anxiety. And also the result of regression analysis to see the effects of self-regulated learning on sub-domains of the career adaptability like responsibility, interpersonal relationship, proactivity, positive attitude showed statistically significant differences to the total score of career adaptability except motivation controlling. Based on the above results, this study suggest the need of mediation related with self-regulation, and also the need of counselling and education to help the medical students suffering from adaptability. Furthermore, suggest following studies searching the multiple variables affecting career adaptability.

As the popularity of single-person media content increases, We investigated the causal relationship between perceived value and intention to recommend to others. Individuality was studied on the tendency to sensation seeking and novelty seeking, which is a tendency to take boredom sensitive to monotonous and repetitive daily routines, and novelty seeking refers to new information and stimuli. The hypothesis was that high sensation seeking and high novelty seeking would perceived emotional value, epistemic value, and economic value for a single person 's media content. Hypothesis testing was performed using multiple regression analysis using SPSS21. As a result of the hypothesis test, The novelty seeking has a positive effect on emotional value, epistemic value, and economic value. Users who want to explore and enjoy new things could perceived the emotional value of having fun, fun, and sadness through single-person content, perceived a epistemic value and enjoy new information and situations as a tool to recognize new stimuli and know what they didn't know. And it could be seen that users perceive the economic value that they can enjoy at low cost or free service. The sensation seeking has a significant effect on epistemic value, but it did not affect emotional value and economic value significantly. Those who have a high tendency to sensation seeking can perceive curiosity about one-person media contents, so that they can perceive epistemic value. However, those who feel that they have not significant influence on economic value and emotional value can easily understand that expecting one's content does not feel bored by paying for a low cost or free service.
