  • The aim of this paper was to review the biomechanics of knife injuries, including those that occur during stabbing rampages. In knife stab attacks, axial force and energy were found to be 1,885 N and 69 J, respectively. The mean velocity of a stabbing motion has been reported to range from 5 to 10 m/sec, with knife motions occurring between 0.62 and 1.07 seconds. This speed appears to surpass the defensive capabilities of unarmed, ordinarily trained law enforcement officers. Therefore, it is advisable to maintain a minimum distance of more than an arm's length from an individual visibly armed with a knife. In training for knife defense, particularly in preparation for close-quarter knife attacks, this timing should be kept in mind. Self-inflicted stab wounds exhibited a higher proportion of wounds to the neck and abdomen than assault wounds. Injuries from assault wounds presented a higher Injury Severity Score, but more procedures were performed on self-inflicted stab wounds. Wound characteristics are not different between nonsuicidal self-injury and suicidal self-wrist cutting injuries. Consequently, trauma surgeons cannot determine a patient's suicidal intent based solely on the characteristics of the wound. In Korea, percent of usage of lethal weapon is increasing. In violence as well as murders, the most frequently used weapon is knife. In the crimes using knife, 4.8% of victims are killed. Therefore, the provision of prehospital care by an emergency medical technician is crucial.

  • The purpose of this article is to propose an alternative viewpoint on medical education, known as the Erudition paradigm. This study aims to confirm the essence of erudition rather than teaching and learning through discussing the foundations of self-directed learning principles in medical education. By reactivating the meaning of self-directed learning, this study debates the proprieties of the erudition paradigm beyond pedagogy; that is to say, the school-oriented educational paradigm. After all, this study reveals that all humans are Homo Eruditio, born with an erudite instinct, and it is necessary to inspire his/her encouragement in erudition by using self-directed learning.

  • Recently, self-efficacy is one of the critical constructs that have been found to influence human decisions about behavior selection and the performance associated with the selected behavior. The construct has been widely adopted and tested In the fields of social psychology and/or other behavioral sciences. In information systems field, however, it has been hardly studied, although computer self-efficacy could have been an important factor explaining and predicting human computer usage behaviors. From this perspective, main purposes of the study is to understand causal relation among the factors influencing computer self- efficacy, computer usage behavior and computer self-efficacy. The research reported in this study have several objectives; 1) to develop a measure of computer self-efficacy, 2) to Identify the factors influencing self-efficacy, and 3) to reveal the relationship between self-efficacy and computer usage behavior and then 4) to explain the causal model of computer self-efficacy. By reviewing the literature, past experience, others' use, encouragement by others, and anxiety are selected as the factors influencing computer self-efficacy. Four hypotheses concerning the relationship between each of the variables and computer self-efficacy are tested by LISREL. One more hypothesis about the relationship between computer self-efficacy and computer usage is also tested. The results show that computer self-efficacy is significantly influence by computer anxiety, encouragement by others, and computer experience, and that it is closely correlated with computer usage behavior.

  • While feeling anxious about the risk of exposure of personal information and privacy, users of microblogs and social network services are continuously using them. This study aims to develop a model to investigate this phenomenon. Specifically, this study explores the relationship between personal characteristics (represented by privacy concern and self-presentation) and an individual's self-disclosure. An individual's personal belief (represented by perceived risk and perceived trust) is also tested as an mediator between the relationship. Through a questionnaire survey to 183 twitter users in Korea, the results indicate that self-presentation has a direct influence on self-disclosure as well as an indirect influence through perceived trust. In contrast, privacy concern has not a direct but an indirect negative influence on self-disclosure through perceived risk. In conclusion, self-presentation has a stronger influence on self-disclosure then privacy concern to Twitter users. An individual who has a higher propensity for self-presentation will form a stronger perceived trust on Twitter, which in turn, affects the individual's self-disclosure. On the other hand, an individual who is more concerned with personal privacy will feel more serious about perceived risk, which in turn, negatively influences one's perception of the trust in Twitter as well as his desire for self-disclosure.

  • The purpose of this study was to elucidate to what extent the goals of the leadership training program implemented in a medical college were achieved. Study subjects consisted of 74 first-year premedical students at the College of Medicine of The Catholic University of Korea. All participants completed two questionnaires: an 18-item self-leadership questionnaire asking self-expectation, rehearsal, goal setting, self-rewards, self-judgment and constructive thinking, and a 28-item self-efficacy questionnaire asking preference toward difficult work, efficacy of self-control, and confidence before and after the leadership training program. Students also competed a program satisfaction survey after the program. The collected data were analyzed with a paired t-test, descriptive statistics by IBM SPSS ver. 20.0 (IBM Co., Armonk, NY, USA). Students' overall satisfaction with the program scored 4.06 out of 5. The scores of self-leadership and self-efficacy increased after the leadership training program except for 'confidence' in self-efficacy. The results indicate that an intensive leadership program in a short period of time could help to enhance social competencies such as communication skills, empathy, self-reflection, and teamwork of premedical students.

  • Purpose: This review examined literature relevant to adolescent's health behavior in order to identify key behaviors and factors related to health behaviors for targeting health promotion interventions. Method: A critical review of 29 research articles was carried out using the guidelines suggested by Cooper. Result: The majority of the studies were descriptive and cross-sectional. Generally. the study includes sub-dimensions such as general hygiene and daily life habit, safety and accident prevention, nutrition and eating (tobacco, drinking), exercise, mental health and stress management, health duty (drug, health examination, disease prevention). Factors highly related to health behaviors were age, living areas, economic status, parent health behaviors, parent health concern, social support, friends influence, self-efficacy, self-esteem, locus of control, and the perceived health status. Sex, parent education and health knowledge were not related to health behaviors of adolescents. Conclusion: Several conceptual and methodological problems were identified in the studies review, such as restricted conceptualization of health behaviors and sampling issues which limit the generalizability of the study outcomes. Further research is needed to enhance the concept clarification and generalizablity of the study results.

  • This study aims to explore ways to improve self-censorship tendency in teacher librarians by identifying factors that influence the self-censorship which appears during collection development in elementary school libraries. For this purpose, first, we examined the concept of self-censorship through a review of related literature, then carried out a series of in-depth interviews as a pilot study to develop a questionnaire, which was used for a questionnaire survey. Finally, the survey data was analyzed statistically with SPSS 21.0, a statistical package. As a result, we have discovered statistically significant relationships between self-censorship and the characteristics in collection development policies, school library committees, and the complaints related with the library collections. Based on these results, the factors on the self-censorship were identified in the perception of the school librarians. Based on these results, we suggest to reinforce the function of review and approval of book selection in the school library committee, developed and approved a collection development policy include guidelines for dealing with users' complaints related to library collection, and stipulated a regulation for school library operation to remove inappropriate books from the library collection.

  • This study performed to identify the relationship between job stress and self-efficacy based on the related research review and text network analysis. For the literature review, we performed the search process at three domestic and one foreign database using key words, 'nurse', 'stress', 'self-efficacy'. A total of 18 papers were selected as the target literature. Nine of these studies reported a statistically significant negative correlation between nurses' job stress and self-efficacy. It was difficult to compare between studies' results because of the optional usage of the questionnaires. In addition, a text network analysis was conducted by extracting keywords from the 18 papers. The keyword with the highest frequency of appearance was job stress, and the main words with high frequency of emergence were self-efficacy, hospital, and correlation. To clarify the relationship between the keywords, it is proposed to perform a survey on the influence factors through the development of Korean version measurement.
