As foreign tourists visiting Korea increase and Koreans traveling overseas become more frequent, a study on the level of domestic consumers' acceptance of different cultures and the perception towards products from different cultures is needed. In this study, a perceptual curiosity, which is an individual personality, was divided into Diverse perceptual curiosity and Specific perceptual curiosity, and effects of perceptual curiosity on an attitude towards different cultures and an intention to recommend products from different cultures were examined. To prove validity of measurement items and reliability of data, SPSS and LISREL were used and to prove a hypothesis, a structural equation model was used. The study results showed that the Diverse perceptual curiosity, which is Hypothesis 1, had a positive effect on the attitude towards different cultures while the Specific perceptual curiosity, which is Hypothesis 2, did not have a significant effect on the attitude towards different cultures. In addition, it was shown that the attitude towards different cultures, which is Hypothesis 3, had a significant positive effect on the intention to recommend the products from different cultures.

다국적 선원으로 구성된 선박환경에서 근무하는 선원들에게는 원활한 의사소통을 위한 영어구사능력뿐만 아니라 서로 다른 문화에 적절히 대응하고 융합하는 이문화 커뮤니케이션 능력함양이 절대적으로 요구된다 할 것이다. 특히 필리핀, 중국, 인도, 일본, 인도네시아, 한국, 미얀마를 비롯한 아시아 선원들이 전 세계 선원시장에서 차지하는 비중이 50%에 달하는 점과, 이들 국가들이 영어를 모국어로 사용하고 있지 않은 점을 고려할 때, 아시아 지역 선원들에 대한 해사영어 교육훈련의 중요성은 아무리 강조하여도 지나치지 않을 것이다. 따라서 이 연구에서는 아시아해사영어교육센터에 대한 구성과 역할 및 향후 추진방향 등을 제시하고자 한다.

Online recruitment services have emerged as one of the most popular Internet services, providing job seekers with a comprehensive list of jobs and a search engine. But many recruitment services suffer from shortcomings due to their reliance on traditional client-pull information access model, in manay cases resulting in unfocused search results. Worldjob+, being operated by The Human Resources Development Service of Korea, addresses these problems and uses Splunk, a platform for analyzing machine data, to provide a more proactive and personalised services. It focuses on enhancing the existing system in two different ways: (a) using personalised automated matching techniques to proactively recommend most preferrable profile or specification information for each job opening announcement or recruiting company, (b) and to recommend most preferrable or desirable job opening announcement for each job-seeker. This approach is a feature-free recommendation technique that recommends information items to a given user based on what similar users have previously liked. A brief discussion about the potential benefit is also provided as a conclusion.

As a recent cyber attack has a characteristic that is intellectual, advanced, and complicated attack against precise purpose and specified object, it becomes extremely hard to recognize or respond when accidents happen. Since a scale of damage is very large, a corresponding system about this situation is urgent in national aspect. Existing data center or integration security framework of computer lab is evaluated to be a behind system when it corresponds to cyber attack. Therefore, this study suggests a better sophisticated next generation convergence security framework in order to prevent from attacks based on advanced persistent threat. Suggested next generation convergence security framework is designed to have preemptive responses possibly against APT attack consisting of five hierarchical steps in domain security layer, domain connection layer, action visibility layer, action control layer and convergence correspondence layer. In domain connection layer suggests security instruction and direction in domain of administration, physical and technical security. Domain security layer have consistency of status information among security domain. A visibility layer of Intellectual attack action consists of data gathering, comparison, decision, lifespan cycle. Action visibility layer is a layer to control visibility action. Lastly, convergence correspond layer suggests a corresponding system of before and after APT attack. An introduction of suggested next generation convergence security framework will execute a better improved security control about continuous, intellectual security threat.

This paper proposes a resource management and allocation algorithm to guarantee QoS continuity of realtime multimedia services and to maximize the resource utilization in heterogeneous wireless networks simultaneously. This scheme reserves the appropriate resources to be used by real-time multimedia services and allocates those resources left unused due to decreased transmission rate of realtime services to non-realtime services. Those resources can be preempted by the need of realtime services later. Performances are analyzed by simulation.

관상동맥은 전기적으로 자극하여도 활동전위가 쉽게 유발되지 않는 조직인데, 이는 세포내의 $Ca^{2+}$에 의해서 활성화되는 $K^{+}$통로때문이라고 여겨지고 있다. 저자들은 단일 이온통로 수준에서 이러한 관상동맥 $K^{+}$ 통로의 성질을 조사하고, 아울러 $K^{+}$ 통로 개방제를 포함한 몇가지 약물이 $K^{+}$ 통로에 미치는 영향을 알아보고자 본 연구를 수행하였다. 막소포는 돼지의 심장에서 관상동맥을 분리하여 균질화 및 원심분리하여 준비하였으며, sucrose 20/30%에 있는 층을 취하여 분주한 후 -7$0^{\circ}C$로 보관하여 사용하였다. 평지방막은 1-palmitoyl, 2-oleoyl-phosphatidyl ethanolamine과 1-palmitoyl, 2-oleoyl phosphatidylcholine (4:1)을 n-decane에 녹인지방액(25mg/m1)을 200 $\mu\textrm{m}$의 구멍에 칠하여 만들었다. 단일 $K^{+}$ 통로는 막소포 (1-5$\mu\textrm{g}$/ml)를 평지방막의한쪽에 추가하고 자석으로 저어 융합이 되도록 하였으며, 통로의 활성은 막의 양쪽에 150 mM KCI, 10 mM HEPES-KOH, 0.5 mM EGTA, 0.6 mM $CaCl_2$ (pH 7.2)로 된용액이 존재하는 상태에서 막전압을 다르게 하며 기록하였다. 단일 이온 통로 전류는 amplifier를 통하여 VCR tape에 녹화하여 후에 분석에 이용하였으며, 동시에 종이기록지에 기록하였다. 단일이온통로 활성의 분석은 pClamp (Ver5.5)를 이용하여 수행하였다. 관상동맥에서 가장 흔히 기록되는 이온통로는 막전압과 $Ca^{2+}$의 농도에 의하여 변하는 $K^{+}$ 통로이었는데 pCa 4.0과 -10 mV에서 초기 활성도(Po)는 0.1에서 0.8까지 다양하였다. 전류와 전압과의 관계는 -60 - +60mV의 전압범위에서 직선형이었다.

Recently, the artificial intelligence deep learning field has been hard to commercialize due to the high computing power and the price problem of computing resources. In this paper, we apply a double pruning techniques to evaluate the performance of the in-depth neural network and various datasets. Double pruning combines basic Network-slimming and Parameter-prunning. Our proposed technique has the advantage of reducing the parameters that are not important to the existing learning and improving the speed without compromising the learning accuracy. After training various datasets, the pruning ratio was increased to reduce the size of the model.We confirmed that MobileNet-V3 showed the highest performance as a result of NetScore performance analysis. We confirmed that the performance after pruning was the highest in MobileNet-V3 consisting of depthwise seperable convolution neural networks in the Cifar 10 dataset, and VGGNet and ResNet in traditional convolutional neural networks also increased significantly.
