GPU 상에서의 효율적인 암호 구현을 위해서는 GPU 내부의 자원인 메모리와 명령어셋을 구현하고자 하는 암호 구조에 맞추어 사용하는 것이 중요하다. 본 논문에서는 Blowfish와 RC4를 최신 GPU 프로세서 상에서 최적 구현해 보고 성능을 저하시키는 요인들과 향상시키는 요인들을 비교 분석한다. 특히 파일암호화와 패스워드 크래킹에서 발생하는 암호화 구현 고려 사항에 대해 확인하며 해당 특징이 GPU 암호 구현 상에서 미치는 영향에 대해 확인해 보도록 한다. 마지막으로 앞에서 구현한 결과물의 성능을 저하시키는 요소에 대한 분석을 기반으로하여 높은 GPU 내성을 가지는 암호 설계를 위해 필요한 구조에 대해 확인해 보도록 한다.

The purpose of this study was to compare special education teacher with fellow workers in which skills and skill categories were judged critical to job success for individuals with intellectual disabilities. The results obtained from the study were as follows: First, both groups ranked work-related skill category most relevant for job success. Special education teachers deemed 'following instruction' and 'interest in the job' as critical to job success. And fellow workers ranked 'following instruction' and 'neatness' most important factors. The results of this study give us suggestions as to develop the vocational curriculum for individuals with intellectual disabilities.

This study is to find out what are the factors influencing upon the convergent TV viewing experiences. Socio-demographic variables are identified as the most influential ones. Viewing modes are more influential than the media utilization factors. Comparing the detailed dimensions of TV viewing experiences, time and content selectivity are more influenced by TV viewing modes, while sociability and interactivity are more affected by socio-demographic variables relatively. This study has academic significance in that it is an exploratory empirical study on factors influencing on the TV viewing experiences.

This study is empirical research to understand degree of social support and to analysis influence of social support on life's satisfaction of the marriage immigrant women. By precedent study, social support was classified by emotional support factor, evaluating support factor, material support factor and informational support factor. To achieve oblectives of study, it was sampling, aurvey and statistical anlysis. According to result of study, only evaluating support factor was appeared to attentional influence statistically on life's satisfaction of them. Therefore for life's satisfaction of the marriage immigrant women, it have to evaluating support, for example acceptance of valuation and personality, praise, and encouragement on them.

The purpose of this study was to analyze the effects of middle school students' health factors and eating behaviors on their oral symptoms using the data from 30,885 students in the 13th Korea Youth Risk Behavior Web-Based Survey in 2017. The logistic regression for the effects of the health factors and eating behaviors on the oral symptoms were analyzed using a logistic regression method. The results showed that the groups of higher levels of achievement, and stress, lower daily frequency of tooth-brushing, and no intake of processing meat led to significantly higher levels for toothache and gingival pain recognition. Also, the higher halitosis recognizers had significantly higher levels of stress and the lower daily frequency of tooth-brushing. In conclusion, adolescents' health factors and eating behaviors affected their oral symptoms. This study is expected to help development of a oral health education program that can prevent these oral symptoms.

The purpose of this study was to explore convergence on the theory of unpleasant symptom, and factors affecting quality of life of liver cirrhosis patients. A total of 198 liver cirrhosis patients were recruited symptom experiences, physiologic factors, psychological factors, situational factors, and quality of life. Data were collected from March, to May, 2014 and analyzed using one-way ANOVA, Pearson correlations, multiple regressions analysis with PASW (SPSS) 21.0. Variables such as duration of liver cirrhosis(${\beta}=.19$, p<.001), symptom experiences(${\beta}=.19$, p=.032), physical(${\beta}=.15$, p=.008), psychological(${\beta}=.39$, p<.001) and situational factors(${\beta}=.32$, p<.001) explained 51.8% of variance in quality of life(F=15.57, p<.001). The symptom experiences, physiological, psychological and situational factors should be considered for caring liver cirrhosis patients. Symptoms of postmyocardial infarction (post-MI) patients at risk for progression to heart.

최근 디지털 기술의 발탈로 방송과 통신의 경계가 허물어지면서 지금까지 없었던 새로운 융합서비스들이 지속적으로 출현하고 있다. 그동안의 방송과 통신은 독자적인 영역을 고집하며 서로 독립적으로 발전해왔다. 하지만, 방송통신융합기술의 발전, 네트워크 성능 향상 그리고 스마트 기기의 폭발적인 증가 등 여러 가지 요인으로 인해 다양한 융합서비스들이 출현 하게 되었으며 빠른 속도로 발전, 확산되고 있다. 논문은 융합서비스의 대표주자인 IPTV 서비스 보안 이슈는 물론 스마트TV, N-Screen, OPEN IPTV 등 IPTV가 발전함에 따라 새롭게 등장하는 융합서비스에 대한 보안위협을 분석하고 그에 대한 대응방안을 제시한다.

세포융합방법을 사용하여 성장증인 포유동물의 난자에 들어있는 성숙억제요인(maturation inhibiting activity, 1연Al에 대해 조사하였다. 성장중인 생쥐난자와 성장한 미성숙난자를 1:1로 융합하여 배양했을 서 (14-17시간)에는 거의 모두 핵붕괴를 일으키었으나(90oyo), 2:1로 융합했을 때는 대부분(약 64%) 3개의 핵을 모두 간직하고 있었다. 돼지난자의 경우는 성장중인 것깎 성장한 것을 1:1로 융합하여 배양했을 때에도 융합체들은 모두 핵을 간직하고 있었으며 돼지의 성장중인 난자와 생쥐의 성장한 난자를 융합했을 때에도 모두 핵을 보존하고 있었다. 이에 반하여 돼지와 생쥐 모두에서 성장한 난자끼리 융합했을 때에는 예외없이 핵붕괴가 일어났다. 이러한 결과는 성장중인 생쥐나 돼지의 난자에 각IA가 존재한다는 열과 이종간에도 효과가 있다는 것을 보여주고 있다. 또한 이는 MIA와 성숙촉진요인(maturation promoting factor, MPH의 상대적인 양의 변화가 난자의 성숙조절에 증요한 9f할을 한다는 것을 시사해주고 있다.In an attempt to elucidate the nature of maturation inhibiting activity (MIA) in growing mamma-lian oocvtes, growing mouse and pig oocytes incompetent to resume meiosis were fused with fully grown immature oocvtes in various combinations and cultured for 14-17 hours. In slant cells composed of two mouse growing ooh임es and one large immature oocyte (2:기, their GVs remained well conserved (about 64%) after culture, but not in the ceils composed of one by one pairs. In giant cells of pig composed of one growing and onto large immature oocytes, both GVs remained conserved. In the cells composed of one pig growing and one mouse large oocytes, both GVs were also conserved. In contrast to this, pairs of large mouse oocvtes or those of large pig oocvtes had no CVs after culture. Thus, we could acertain the existEnce of MIA and none-pecificty of it in the mouse and pig growing oocvtes. The results also suggest that the relative amount of substances showlns MfA or MPF activity may be important in the regulation of oocyte amount of substances showing MIA or MPF activity may be important in the regulation of oocyte maturation.

In the construction industry, there is a growing demand for new programs incorporating IT applications. In construction, initiatives calling for changes ensuring the improvement of productivity, quality and safety, and for the strengthening of global competitiveness, have contributed to the increased need for exploring new markets. Moreover, the government's supportive policies have helped develop profit models. Meanwhile, the industry and the government have supported the efforts for identifying and disseminating successful case studies - as part of the strategy for evaluating and promoting the developed programs. However, the criteria for identifying/evaluating successful cases remain vague, and the viewpoints of participants differ depending on their disciplines. These discrepancies could lead to inconsistent results. Thus, it is imperative that a criterion be provided, upon which to judge the success or failure of implementation cases and to disseminate role models. It is also imperative that a direction of improvement be proposed. This study was conducted to propose the criteria for and process of evaluating the success of construction-IT convergence to help promote the construction industry incorporating IT applications. To that end, success factors for and the significance of IT-incorporated construction were identified.

The present study analyzes the main factor having an effect on the convergence dental hygienist's self-esteem through the survey to them. A self-leadership and professional self-conception show meaningful result with higher score in the group with higher self-respect than that of lower one(p<.001). Also the higher hygienist's self-esteem, the higher clinic practice ability(p<.01). There is negative correlation with self-esteem in emotional labor(p<.01) and exhaustion(p<.01). However, the positive correlations are presented in self-leadership(p<.01), professional self-conception(p<.01) and clinic practice ability(p<.01) with self-respect. The factors influenced on self-esteem are clinic practice ability(p<.05) and exhaustion(p<.01). In results, the organized convergence program and education considering self-esteem in the hospital should be accomplished systemically to enhance the clinic practice ability of each hygienist.
