  • The statistics of Korean Maritime Safety Tribunal and Japan Marine Accidents Inquiry Agency shows that the major muses of collision at sea are Improper lookout and Non-compliance with marine traffic rules. Those two muses are occupying more than 70% of collision, and it's clear that those muses are undoubtedly closely related to simple human error. In this paper we tried to find out the root muses of this kind of human error of OOWs(officers on watch) through risk identification method and studied how to tackle them via risk control theory. In conclusion, the measures studied in this paper could be applied to help OOWs avoid their own human error as well as be used in shipping company for their fleets' safety management.

  • The purpose of this study was to examine the effects of applying a program to enhance social information processing ability in schizophrenic patients. We confirmed the positive effects of the program on the theories of mind and attribution style, which are the social information elements of patients, and confirmed the effect of decreasing paranoid ideation. We used the theory of mind(hinting task, the false belief task), the attributional style questionnaire(external bias, personal bias), and the paranoia scale to test the effectiveness of the program. Specifically, in theory of mind, hinting task performance was improved(t=4.14, p=.000),. The scores of personal bias(t=-7.9, p=.000) and paranoid ideation(t=-2.98, p=.004) decreased. Further research is needed to verify the effectiveness of meta - cognitive training to enhance social information processing.

  • 디지털 디바이스와 네트워크의 발전에 의해 커뮤니케이션 기술은 용이해졌지만, 반대로 광고에 대한 소비자의 인식은 가장 부정적인 모습이다. 이런 배경에서 소셜 미디어를 이용한 브랜드 스토리텔링은 효율적인 마케팅 수단으로 주목받고 있다. 하지만 빠르게 성장하고 있는 VR(가상현실), AR(증강현실), 그리고 MR(혼합현실) 미디어 환경은 브랜드 스토리텔링 마케터들에게 새로운 가능성을 제공하고 있다. 본 연구는 서사몰입 이론을 중심으로 MR 미디어 서비스에 대한 논의를 통해 브랜드 마케팅의 방향과 시사점들을 제시하는데 목적을 가지고 있다.

  • This paper focuses on the analysis of the Chinese transliterations of English place names in the Optimality Theory (OT) [1]. Three groups of monosyllabic, disyllabic and multisyllabic English place names are analyzed to represent the hierarchical ranking of both Markedness and Faithfulness constraints in terms of sound epenthesis, which is one of the most important repair strategies named the Preservation Principle [2] devised to "preserve" every source segment (or sound) of the target place names. By doing so, this paper tries to answer the question of why sound epenthesis takes place in transliterating words between languages. With the help of the established ranking of the relevant constraints, this paper explains the process of sound epenthesis formally.

  • This study intends to examine gender differences in predictors of Human Papilloma Virus (HPV) vaccination intention based on the Theory of Planned Behavior (TPB). Specifically, this study investigated whether the variables constituting TPB might show differential effects on college men and women's HPV vaccination intention. The current study also examined which specific subjective norms are more influential in explaining HPV vaccination intention of men and women. The results of an online survey revealed that females showed significantly higher intention to get the HPV vaccine and perceived behavioral control than male students. Female students' vaccination intention was best predicted by perceived behavioral control whereas friend norm was the most influential predictor of male students' intention to get the HPV vaccine. The results of this study provide implications for persuasive strategies required to appeal to college men and women to increase HPV vaccination rate.

  • Smartphone security threat has become an important issue in Information Science field following the wide distribution of smartphones. However, there are few studies related to such. Therefore, this study examined the factors affecting the intention of smartphone users to use the mobile vaccine against malware with the Protection Motivation Theory. To secure the reliability of the study, a surveying agency was commissioned. A total of 263 respondents, excluding 37 respondents who are users of iOS, which does not have mobile vaccine in the smart phone, or who gave invalid responses, were surveyed. The results showed that perception of the installed mobile vaccine significantly affected the Response Efficacy and Self-efficacy, and that the Perceived Severity, Perceived Vulnerability, Response Efficacy, and Self-efficacy significantly influenced the intention to use the mobile vaccine. On the other hand, Installation Perception of mobile vaccine itself did not affect the Perceived Severity and Perceived Vulnerability. This study is significant since it presented the new evaluation model of threat evaluation and response evaluation in the Protection Motivation Theory in accepting the security technology and raised the need for the promotion and exposure of mobile vaccine, since perception of mobile vaccine installation affects the response evaluation. It also found that the promotion must consider the seriousness of smartphone security, outstanding attribute of mobile vaccine, and user-friendliness of mobile vaccine above all.

  • This is qualitative research using grounded theory to examine the experiences that mothers of children with epilepsy can have. Data were collected through in-depth interviews, observation, and memo-taking with a total of 13 participants in this study-10 mothers taking care of children with epilepsy and 3 principal informants-and the data were analyzed using the method developed by Strauss and Corbin (1998). As a result of data analysis, 163 concepts, 26 subcategories and 8 categories were formed through open coding. Such categories were analyzed by the paradigm of the grounded theory, and as a result the experiences of the mothers of epileptic children were based on a causal condition of 'confrontation' and the central phenomenon of 'Wandering around the forest under a yoke'. The contextual conditions, which exerted influence on phenomena, were 'stigma cognition', 'personality traits' and 'health of children.' The action/interaction strategy selected by participants was 'Quietly pulling through: Bracing myself, Getting to know my enemy and myself, Taking care while hiding, Putting out one step at a time, Establishing a foothold. The intervening condition affecting action/interaction was 'the support system', and its result was 'watching.'

  • 저해상도 3D 해저 디지털 지형 모형(Digital terrain model: DTM)의 이미지를 컴퓨터 화면에 확대 표시할 때 데이터가 없는 픽셀은 인위적으로 보간해서 표시할 수밖에 없다. 따라서 본 연구에서는 기존의 선형 보간법의 문제점을 개선하기 위해 저해상도 DTM으로부터 지형정보를 추출하고 이로부터 보간하는 방법을 다룬다. 이를 위해 DTM을 다수의 패치로 분할하고 프랙탈 이론(Fractal theory)를 이용하여 프랙탈 차원을 추정하고, 추정 정보와 원래의 데이터를 근간으로 패치 지형을 Midpoint Displacement법으로 보간하고, 보간된 이미지의 국부적인 기복을 완화해 자연스런 해저지형을 만들기 위해 미디언 필터(Median filter)를 이용한다. 가상의 프랙탈 지형 맵을 이용하여 제안된 알고리즘의 그 유효성을 검정한다.

  • This paper investigates the determinants on decision to conduct seasoned equity offerings (SEOs) of listed companies on the Ho Chi Minh Stock Exchange in Vietnam. Seasoned equity offerings (SEOs) are defined as the issue of more stocks by a firm to raise more capital after a primary issue. Using panel data collected from audited financial statements of 99 listed companies on the Ho Chi Minh Stock Exchange during 2014-2018, the study employs a logit regression model by fixed effects method to examine factors that affect the decision to implement seasoned equity offerings of those companies. The findings of this study show that profit, revenue growth and company's size have a positively significant impact on the decision, while dividend pay-out ratio negatively significantly influences the equity issuing decision. Furthermore, these results are robust after controlling for the forms of equity offerings, i.e. bonus stocks, stock dividends and rights to buy shares. These findings are consistent with economic theories such as agency theory, pecking order theory, and growth opportunity theory, and also could be explained by the real situations of the Vietnamese stock exchange. This study has important implications for corporate managers, policy makers and investors.

  • The Extraposition phenomenon in English has been analyzed mainly through two approaches: a derivational approach under the Principles & Parameters framework (P&P) and a representational approach under the early Minimalist framework (MP). The first one tries to understand the phenomenon as a result of the movement of a Big Subject first to the end of a sentence which is then followed by the insertion of an expletive 'it' to the empty Subject position. On the other hand, the second one tries to understand it by way of assuming a Big Subject originally base-generated at the end of a sentence which is followed by the insertion of an expletive 'it' to the empty Subject position. The two approaches, however, are not free from theoretical defects at all: the full derivational approach was under controversy in terms of (1) the failure of the Binding Theory and (2) its inability to suggest anything about the marginal reading issue. On the while, the representational approach has been argued (1) to violate the thematic hierarchy that should be kept in D-structure, and (2) to be also unable to suggest the slightest difference in marginal reading issue as the first one. In this paper I focus mainly on analyzing the 'It'-Extraposition phenomenon in the Optimality Theory. I will show that by way of (i) some newly developed constraints such as Subj., and AHSubj. and (ii) a constraint hierarchy of Subj.>>AHSubj., the controversies of 'It-Extraposition' such as (1) the analysis of construction and (2) the very closely related issue of 'marginal reading issue' can be explained properly.
