Due to recent growth in IT industry along with the expansion of smartphone, we came to connect to the Internet wherever and whenever we are. However, this causes negative side effects, though. One of them is a rapid increase of the financial crimes such as the Phishing and the SMishing. There have been many on-going researches about crimes such as Phishing and SMishing to protect users. However, the study about sharing knowledge on SNS to prevent such a crime can be hardly found. Based on social identity theory, we conduct the research about factors on SNS users' intention to share the information security knowledge on SNS. As a result, we found that knowledge provision self-efficacy has a significant impact on self-expression. In addition, it also found out self-expression, awareness about information security and the sense of belonging have a significant impact respectively on the intention to share the information security knowledge on SNS. On the other hand, the altruism didn't have a significant impact to the intention to share information security knowledge on SNS. With this research as a starting point, it seems necessary to expand its range to all types of online community in the future for the generalization of the hypotheses.

This study investigated how many and which articles readers read in daily newspapers. Distinguished from previous research that measured readers' perception of their reading habits, this study picked up readers who read the newspaper in the morning, showed them every article in the newspaper, and asked them whether they read each article. This method enhanced the accuracy of measuring subjects‘ reading behavior. According to the results, 6.2% of the readers read at least half of the articles of the general section in the newspaper. Fewer readers went over the economic section of the newspaper. It was 4.1% of the readers. There were only 1.1% of readers who did not read any article of the general section, but the rate soared to 26.5% for the economic section. Many newspaper readers did not skip the first five pages of the newspaper, however the highest readership pages were found in the national coverage located in the middle of the general section. On the other hand, few readers read the articles on pages covering culture, international issues, and people. Readership of the top stories showed some unexpected results. The top stories of national coverage located in the middle of the general section were read by more readers than the top stories of the front pages. This study also investigated the difference between young and old readers. The readers of twenties and thirties did not read as many top stories on major pages and editorials as the readers of forties and older.

Motor imagery based Brain-computer Interface(BCI), which has recently attracted attention, is the technique for decoding the user's voluntary motor intention using Electroencephalography(EEG). For classifying the motor imagery, event-related desynchronization(ERD), which is the phenomenon of EEG voltage drop at sensorimotor area in ${\mu}$-band(8-13Hz), has been generally used but this method are not free from the performance degradation of the BCI system because EEG has low spatial resolution and shows different ERD-appearing band according to users. Common spatial pattern(CSP) was proposed to solve the low spatial resolution problem but it has a disadvantage of being very sensitive to frequency-band selection. Discriminative filter bank common spatial pattern(DFBCSP) tried to solve the frequency-band selection problem by using the Fisher ratio of the averaged EEG signal power and establishing discriminative filter bank(DFB) which only includes the feature frequency-band. However, we found that DFB might not include the proper filters showing the spatial pattern of ERD. To solve this problem, we apply a band-selection process using CSP feature vectors and linear discriminant analysis to DFBCSP instead of the averaged EEG signal power. The filter selection results and the classification accuracies of the existing and the proposed methods show that the CSP feature is more effective than signal power feature.

This study aimed to identify the effects of using storytelling techniques in sex education, in which students are encouraged to talk about their experiences with sex and love and helps them form their own sex values and decision-making skills related to sex. A five-period teaching-learning plan covering issues including safe, considerate and responsible sex was developed using the storytelling technique for 134 first-year students in 4 classes. 134 questionnaires were administrated through pre-and post-test and 38 worksheets applying a variety of storytelling activities were analyzed using content analysis. Students were found to have gained a more positive outlook on relationships and a considerate attitude towards others in sex. There was also a significant increase in items considering safe sex, including perceptions on contraception methods and selection of safe contraception methods. The students' sense of sexual responsibility was also enhanced. Results of content analysis found students to have shifted to sex focusing on love and responsibility, and to have grown a stronger sense of responsibility in their relationships. Furthermore, the respondents expressed interest in selecting proper contraception methods and held strongly negative perceptions about abortion.

Korean income data obtained from Korea Labor Panel Survey shows excessive zeros, which may not be properly explained by the Tobit model. In this paper, we analyze the data using a zero-inflated Tobit model to incorporate excessive zeros. A zero-inflated Tobit model consists of two stages. In the first stage, individuals with 0 income are divided into two groups: genuine zero group and random zero group. Individuals in the genuine zero group did not participate labor market since they have no intention to do so. Individuals in the random zero group participated labor market but their incomes are very low and truncated at 0. In the second stage, the Tobit model is assumed to a subset of data combining random zeros and positive observations. Regression models are employed in both stages to obtain the effect of explanatory variables on the participation of labor market and the income amount. Markov chain Monte Carlo methods are applied for the Bayesian analysis of the data. The proposed zero-inflated Tobit model outperforms the Tobit model in model fit and prediction of zero frequency. The analysis results show strong evidence that the probability of participating in the labor market increases with age, decreases with education, and women tend to have stronger intentions on participating in the labor market than men. There also exists moderate evidence that the probability of participating in the labor market decreases with socio-economic status and reserved wage. However, the amount of monthly wage increases with age and education, and it is larger for married than unmarried and for men than women.

A passively fitting prosthesis is an essential prerequisite to attain long-lasting success and maintenance of osseointegration. However, true "passive fit" can not be achieved with the present implant-supported prosthesis fabrication protocol. Many clinical situations are suitably treated with cantilevered implant-supported fixed restorations. The purpose of this study was to compare the stress distribution pattern and magnitude in supporting tissues around ITI implants with cantilevered, implant-supported, screw-retained fixed prosthesis according to the fitness of superstructures. Photoelastic model was made with PL-2 resin (Measurements, Raleigh, USA) and three ITI implants (${\phi}4.1{\times}10mm$) were placed in the mandibular posterior edentulous area distal to the canine. Anterior and posterior extended 4-unit cantilevered FPDs were made with different misfit in the superstructures. 4 types of prosthesis were made by placing a $100{\mu}m$ gap between the abutment and the crown on the second premolar and/or the first molar. Photoelastic stress analysis were carried out to measure the fringe order around the implant supporting structure under simulated loading conditions (30 lb).

The purpose of this study is to compare the perception on family of social workers and clients. Perception of family concept, family function is changing as times passes. But social worker is facing a dilemma because of differences of the perception on family. In order to compare between social worker and client concepts on family, this study compare family concept, familism, gender egalitarianism. Data for analysis were collected from 131 social workers and 134 clients who were purposive sampled. Social worker's recognition of family concept is more acceptable than client's family typology, functional family concept. Analysis shows that client group more higher familism and clients have a low opinion of gender egalitarianism. Thus, social worker may have conflicted with client's family while social worker practices case management or prograss family welfare services. In order to examine the influencing factors on family perception, the defined factors were self-efficacy, family of orgin perception. Controlling for sex, old, marriage on family perception were examined. There were significant effect of old, family-orgin perception to the client's family concept, familism, gender egalitarianism. On the contrary there were significant effect of sex, self-efficacy to the social worker's familism, gender egalitarianism. In conclusion, this study confirmed the difference of family perceptions between social worker and client. But the result of this study suggest that family social work procession or intervention will be investigated concretely.

최근 산업 플랜트의 공정제어 시스템은 복잡하고 대규모화되어 고장 발생시 경제적 손실과 위험성이 증폭되어 규정된 안정서와 신뢰성 확보가 필수적이라 할 수 있다. 고장검출 및 진단기법은 시스템의 신뢰성을 높이기 위한 효과적인 방안을 연구하는 것으로 현대에 들어서 많은 학자들의 관심을 끌고 있으며 실제 계통에 점차적으로 응용되고 있다. 현재까지 개발된 고장검출 및 진단기법은 사용된 프로세스 모델의 형태, 고장검출 진단 알고리즘에 따라 다양하게 분류 될 수 있으며 일반적으로 사용된 모델에 따라 크게 1) 정량적 모델에 근거한 해석적 기법, 2) 정성적 모델에 근거한 기법, 3) 지식기반 진단 기법으로 구분 할 수 있다. 이중 정량적 모델 기법은 대상계통의 수학적 모델에 근거하여 운전 데이터를 분석함으로서 고장검출 진단을 수행하는 해석적 기법으로서 근본적으로 계통의 정확한 수학적 모델을 요구하므로 불확실성을 포함한 계통 및 비선형성이 강한 계통등에는 적용이 곤란하다. 정성적 모델 및 지식기반 기법은 정량적 진단 기법과는 달리 대상 프로세스에 대한 수학적 모델 대신에 운전자의 경험과 프로세스 변수간의 상호 작용 및 고장의 전파과정, 고장원인과 증상과의 직접적인 관계에 대한 구조적 지식에 근거한 것으로 고장원인에 대한 계통의 동작을 추론 할 수 있으며, 상황 변화에 따른 영향을 예측할 수 있다. 본 논문에서는 정성적 모델 및 지식기반 기법에 근거한 고장검출 및 진단 기술을 화력 발전소 보일로 프로세스에 적용하여 정성적 시뮬레이션에 의한 설비의 고장을 조기에 발견하여 고장 파급으로 인한 발전 정지 및 설비의 손상 확대를 방지하고 고장 발생시 신속한 원인 규명 및 후속 조치관련 정보들을 운전원에게 제공할 목적으로 현재 전력원에서 개발중인 지능형 경보시스템에 대하여 기술하고자 한다.음과 같이 설명하였다. 서로 상반되는 것들이 다음과 같이 설명하였다. 서로 상반되는 것들이 부딛힘이 없이 공존하고 일상의 논리가 무시된다. 부정, 의심이 없고 확실한 것이 없다. 한 대상에 가졌던 생각이 다른 대상에 옮겨간다(displacement). 한 대상이 여러 대상이 갖고 있는 의미를 함축하고 있다(condensation). 시각적인 순서가 무시된다. 마음속의 생각과 외부의 실제적인 일을 구분하지 못한다. 시간 상의 순서가 있다가 없다가 한다. 차례로 일어나야 할 일이 동시에 한꺼번에 일어난다. 대상들이 서로 비슷해지고 동시에 있을 수 없는 대상들이 함께 나타난다. 사고의 정상적인 구조가 와해된다.

This paper is to address the consonance between Confucianism and Christianity, focusing on the first-generation clergy in Andong, North Gyeongsang Province, Korea. Andong has turned out many Confucian scholars since Yi Hwang, and thus founded the school of Togye (Yi Hwang's nom de plume). Meanwhile, some of Confucians in Andong converted to Christianity after reading the Bible. Thus, their religious activities and their interpretation of the Bible Confucian factors smacked of Confucianism, which suggests a need to reestablish the relationship between Confucianism and Christianity. This study produced the following results: First, the converts did not aspire to Christianity itself but to saving their country. The first-generation clergy in Andong wanted to sublimate their patriotic and Confucian spirits into Christianity, which is backed up by the independence movement planned jointly by Confucians and Christians in Andong. As for Confucians in Andong, their devotion to their country was a cause of the conversion to Christianity. Second, it was small wonder that Christianity was harmonious with Confucianism at least for early Christianity in Andong. In those days, Confucians in Andong had to achieve their realistic goals and thus did not need to deny Christianity. To relieve the national suffering, they had more need of Christian religiosity than Confucian morality. Likewise, missionaries wanted to propagate Christianity, and therefore did not deny the worldliness of Confucianism. On this wise, the two kept their identities and at the same time could compensate for their shortcomings from each other. This study names such Korean Christianity a 'humanistic religion.'
