많은 조직들이 여전히 정보보안 수준을 향상시키기 위해 공식적/비공식적 통제 메커니즘(예. 정책, 절차, 조직 문화)의 향상에 상당한 노력을 쏟고 있으나, 이러한 메커니즘의 영향과 효과에 대한 연구는 아직 초기 수준이다. 보안 정책의 실행가능성을 높이기 위한 가장 확실한 방법 중 하나는 준수자들로 하여금 정책을 이해하고 필수요소로 받아들이게 하는 것이다. 하지만 조직 구성원들의 보안에 관한 지식 및 인지의 부족은 여전히 주요한 문제이다. 그동안 많은 연구에서 보안 지식과 인지를 높이기 위해 보안인식 교육의 수행을 주장하였으나 많은 연구에서 제시된 결과는 일관되지 않는다. 따라서 본 연구는 왜 보안인식 교육이 효과적이지 못한지 그 의문에 대한 해답을 찾기 위해 수행되었다.

In accident analysis, it is essential to understand the causal pathways of the accident. Although numerous accident models have been developed to help analysts understand how and why an accident occurs, most of them do not include all elements related to the accident in various fields. Thus analysis of human error accidents in railway operations using these existing models may be possible, but inevitably incomplete. For a more thorough analysis of the accidents in railway operations, a more exhaustive model of accident causation is needed. This paper briefly reviews four recent accident causation models, and proposes a new model that overcomes the limitations of the existing models for the analysis of human error accidents in railway operations. In addition, the usefulness and comprehensiveness of the proposed model is briefly tested by explaining 12 railway accident cases with the model. The proposed accident causation model is expected to improve understanding of how and why an accident/incident occurs, and help prevent analysts from missing any important aspect of human error accidents in railway operations

Due to the low conversion rate of social commerce, its sustainability is questioned. To solve this problem, this study aims to verify the different antecedents between visit intention and purchase intention. For a visit intention, this study employs the concept of the scarcity heuristic and its momentary characteristic. The scarcity heuristic is created by a scarcity of time and quantity, and provisional coupons. In previous studies, the scarcity heuristic has often been treated as a major factor in which to influence purchase intention. However, this study examines the scarcity heuristic only as an antecedent of the visit intention, not of the purchase intention, because of its momentary characteristic. Contrary to previous studies, as this study expected, the attributes of the scarcity heuristic had a significant relationship only with the visit intention in social commerce. Additionally, the results suggest that there are two distinct intentions in social commerce: visit intention and purchase intention. This study verified that the antecedents of the two distinct intentions are different from one another. This study helps to understand why people visit social commerce sites regularly but do not buy.

In the school mathematics, the negative numbers have been instructed by means of intuitive models(concrete situation models, number line model, colour counter model), inductive-extrapolation approach, and the formal approach using the inverse operation relations. These instructions on the negative numbers have caused students to have the difficulty in understanding especially why the rules of signs hold. It is due to the fact that those models are complicated, inconsistent, and incomplete. So, students usually should memorize the sign rules. In this study we studied on the didactical phenomenology of the negative numbers as a foundational study for the improvement of teaching negative numbers. First, we analysed the formal nature of the negative numbers and the cognitive obstructions which have showed up in the historic-genetic process of them. Second, we investigated what the middle school students know about the negative numbers and their operations, which they have learned according to the current national curriculum. The results showed that the degree they understand the reasons why the sign rules hold was low Third, we instructed the middle school students about the negative number and its operations using the formal approach as Freudenthal suggest ed. And we investigated whether students understand the formal approach or not. And we analysed the validity of the new teaching method of the negative numbers. The results showed that students didn't understand the formal approach well. And finally we discussed the directions for improving the instruction of the negative numbers on the ground of these didactical phenomenological analysis.

Particles existing in a hard disk drive are known as a major source of TA(thermal asperity). Researchers have investigated how particles induce the TA phenomena, but have not verified yet the reason why and how particles are generated in a HDD. The objective of this study is to investigate why and how particles are generated, and in what condition, the largest number of particles is generated. The number of particles generated in a HDD was measured over the landing zone after various rest times of slider and during various motions and positions of slider. It is found that the large number of particles was generated when the HDD was turned on after a long rest time of slider and that a few of particles were continuously generated when the slider flied over the disk surface. It is thought that the number of particles generated in a HDD was related to the rest time of slider because the rest time of slider increased stiction, and that there were intermittent contacts between the slider and the disk surface when the slider flied over the disk surface.

The purpose of this study is to find out why Whitney Houston gave healing to people around the world based on Shin Jae-hyo's gwangdaeron (clown theory). In Korean music, gwangdae (廣大, the title of clown) is a nickname dedicated to outstanding artists. Not only is it a clown that cannot be a person, but it does not give a clown a nickname for doing art activities. This is why Shin Jae-hyo, a pansori (Pansori epic chant) theorist and critic in the late 19th century of the Joseon Dynasty, presented the virtues of outstanding artists. There are four outstanding clown conditions claimed by Shin Jae-hyo: appearance (人物), words (辭說), perfect vocal music (得音) and wonderful movements (neoreumsae). These conditions show how difficult it is to be a gwangdae (a prominent artist), or an accomplished artist. We think Whitney Houston is a famous singer who fits these conditions. In her heyday, she was optimized for Shin Jae-hyo's clown theory, while her post-2007 moves are regrettable. However, it is clear that he is a singer who fits well with the title of America's greatest clown. In conclusion, I felt that the best emotion through music was the best healing, and that the best singer was becoming the best healer.

The study aims to define the career competency of HRD practitioners based on an intelligent career framework. This intelligent career framework has been described as having been achieved by the accumulation of career capital through the three ways of knowing, including knowing why, knowing how, and knowing with whom. The data were collected from the interviews with 15 HRD practitioners. Semi-structured interviews were used to collect data from the HRD practitioners. For the orientation about the interview, the researcher explained the importance of gathering data about the personal experiences of the respondents on their work and career. After that explanation, the researcher asked several questions based on the pre-structured interview guide. The data collected were qualitatively analyzed on the basis of the intelligent career framework. Based on the analysis of the interviews, the subcategories of each way of knowing competency were identified. For the knowing why, identity, credibility, and career clarity were identified. The subcategories of knowing how are remaining updates, hard skills, and soft skills, while the subcategories of knowing with whom are personal networking and professional networking. The interdependency among the three career competencies was found. The findings provide theoretical implications of applying an intelligent career framework.

Purpose: This study attempts to explain why online luxury shopping malls have implemented a difficult registration process and membership fees. These features weaken online shopping convenience, one of the major reasons why people shop online instead of offline. Therefore, this study scrutinizes the effects of membership features on trust, focusing on the moderating effects of registration difficulty and membership fees. Research design, data and methodology: A survey method with a total of 296 survey data was used. A 2 × 2 × 2 factorial design was employed. The three independent variables are price discount rate (20% vs. 70%), registration difficulty (low vs. high), and membership fees (yes vs. no). Results: The results reveal that a price discount rate has a negative effect on trust, whereas membership fees and registration difficulty moderate its negative effect on trust. Conclusions: A high price discount rate lowers trust for online luxury shopping malls. Meanwhile, registration difficulty and membership fees can be used to prevent consumers from losing trust caused by the high price discount rate. Therefore, registration difficulty and membership fees are signals implying that not everyone can use these private online shopping malls, which provide low prices for luxury items.

Purpose While new versions of mobile applications could offer users better computing environment, users are not always comfortable with them for various reasons. Considering making update decisions is important task for users, it is crucial for us to understand users' behavior and attitude on app updates. The purpose of this study is to explain why mobile users succumb to both reactance toward the update and satisfaction to the current version, ultimately leading them to feel the regret by employing three theoretical perspectives including regret theory, status quo bias theory and the dual model. Design/methodology/approach Survey data collected from 204 mobile users was used to test the research model using partial least squares analysis. The results have shown that both reactance toward the update and satisfaction to the current version have negative impacts on individuals' decisions to update, which leading to their regret after updating the applications Findings By integrating both status quo bias and regret theory in the model, this study tried to explain why mobile users feel regret in application update settings. More specifically, this study has proposed a novel framework that introduces an individual's update decision on mobile applications.

This study classifies black fashion-mania by each type based on their motivation for wearing black fashion as well as verifies how they express their style. To achieve the objectives of this study, the research questions are as follows. First, the images of black fashion-manias are classified. Second, each type of black fashion enthusiasts' motivations for wearing black fashion are verified. Last, black fashion-mania style are analyzed according to image types. In order to answer the research questions, a literature review and in-depth interviews (total 30 respondents (male 15, female 15) were executed. As a result, black fashion-manias use black fashion for self protection, their self-images such as charismatic professional image, modern sophisticated image, body-conscious sexy image, avant garde image which is an anti-fashion norm and unique image. The strong reason why black fashion-manias insist on black fashion is to 'look cooler'. The expressions could be articulated from sophisticated styling techniques that appear to be undecorated rather than an overt decorated styling. It is helpful information to plan black fashion products and to establish a design direction that requires an understanding of why black fashion is pursued, while promoting an understanding of groups of black fashion-mania.
