Recently, many scholars have emphasized the importance of English listening ability for smoother communication. Most audio materials, however, were recorded in a quiet sound-proof booth. Therefore, students who have spent so much time listening to the ideal audio materials are expected to have difficulty communicating with native speakers in the real life. In this study, we examined how well thirty three Korean university students and five native speakers will repeat the recorded English sentences under noise and speed conditions. The subjects' production was scored by listening to each recorded sentence and counting the number of words correctly produced and determined the percent ratios of correctly produced words to the total words in each sentence. Results showed that the student group correctly repeated around 65% of all the words in each sentence while the native speakers demonstrated almost perfect match. It seemed that the students had difficulty perceiving and repeating function words in various conditions. Also, high-proficiency student group outperformed the low-proficiency student group particularly in their repetition of function words. In addition, the student subjects' accuracy of repetition remarkably dropped when the normal sentences were both sped up and mixed with noise. Finally, it was observed that the Korean students' percent correct ratio fell down as the stimulus sentence became longer.

This study aims to determine the correlation between the apartment resident community and housing satisfaction and suggest which factors can contribute to improving the local community's housing environment and satisfaction by means of the local inhabitants and apartment residents participating in co-managing the community. The study results are as follows. Firstly, the apartment resident community had a positive effect on housing satisfaction but the effects were insignificant. This revealed that residents' interest in communicating with the resident community was low due to various organizations such as the women's association, election committee, and autonomous society being used as means to pursue personal gain rather than the development of the entire apartment. Secondly, the vitalization of the apartment resident community had a positive effect on housing satisfaction. The analysis results showed that the higher the level of unity and volunteering activities of residents, the more improved the resident vitalization programs are being managed, and the higher the level of resident participation, the higher the housing satisfaction. Lastly, this study suggests the supplementation and upgrading of apartment community facilities into complex community facilities as a means to unify the residents and vitalize the resident community. To vitalize the resident community and strengthen the community spirit, the residents will need to voluntarily create a community hub by forming community-tailored associations and programs through connections with local governments and businesses.

Authentication mechanisms coupled with strong encryption techniques are used for network security purposes; however, given sufficient time, well-equipped intruders are successful for compromising system security. The authentication protocols often fail when they are analysed critically. Formal approaches have emerged to analyse protocol failures. In this study, Communicating Sequential Processes (CSP) which is an abstract language designed especially for the description of communication patterns is employed. Rank functions are also used for verification and analysis which are helpful to establish that some critical information is not available to the intruder. In order to establish this, by assigning a value or rank to each critical information, it is shown that all the critical information that can be generated within the network have a particular characterizing property. This paper presents an application of rank functions approach to an authentication protocol that combines delaying the decryption process with timed authentication while keys are dynamically renewed under pseudo-secure situations. The analysis and verification of authentication properties and results are presented and discussed.

The purpose of this study is to investigate the various expressions in fashion design using logo. For this study, fashion magazines such as Vogue, Elle, WWD, Hi Fashion, Mode et Mode, Fashion News, Collezioni were analyzed. A corporate identity consists of the logo and name owned by a company together with the rules and guidance on how these are to be used, for example in printed material such as letterheads, catalogues and reports, in advertising, marketing and promotion, and on produsts and services. Logos provide the bedrock for the development of corporate identities, for the evolution of commercial brands, and for the nurturing of corporate culture. Logo is a primary means of communicating corporate values to customers and designers. It represents an asset of incalculable value, because it has been consistently maintained and protected over the years. The logo is the cornerstone of the company‘s image and the style of a logo or products name must harmonize with the feeling of the product or brand image. Fashion designers today are using their logos in different forms of communication. It is common to see a brand’s logo proudly emblazoned the classic chic garments as well as accessories such as bags, shoes, caps. The consumer, then becomes a ‘walking ad’ for the brand.

The human heart is a complex organ in which many complicated congenital defects may happen and some of them require surgical intervention. Due to the vast complexity of varied anatomical presentations, establishing an accurate and consistent nomenclature system is utmost important to facilitate effective communication among pediatric cardiologists, cardiothoracic surgeons and radiologists. The Van Praagh segmental approach to the complex congenital heart disease (CHD) was developed in the 1960s and has been used widely as the language for describing complex anatomy of CHD over the decades. It utilizes a systematic and sequential method to describe the cardiac segments and connections which in turn allows accurate, comprehensive and unambiguous description of CHD. It can also be applied to multiple imaging modalities such as echocardiogram, cardiac CT and MRI. The Van Praagh notation demonstrates a group of three letters, with each letter representative for a key embryologic region of cardiac anatomy: the atria, ventricles and great vessels. By using a 3-steps approach, we can evaluate complex CHD precisely and have no difficulties in communicating with other medial colleague. This pictorial essay revisits the logical steps of segmental approach, followed by a pictorial illustration of its application.

The study of Web MGIS(Marine Geographic Information System) based on the SVG(Scalable Vector Graphics) is mainly performed on effective methodologies which transform real world data to computing world data. Web GUI system has its own target on reliable data service by acquisition of geometric information using HYCOM(HYbrid Coordinate Ocean Model), accurate measurement and graphical visualization. This type of raw data visualization can be built without software tools, yet is incredibly useful for interpreting and communicating data. Even simple visualizations can aid in the interpretation of complex hydrodynamic relationships that are frequently encountered in the marine environment. The Web MGIS provides an easy way for hydrodynamic geoscientists to construct complex visualizations that can be viewed with free software. This study proposes a Web GUI MGIS using FVCOM(Finite Volume Coastal Ocean Model). Finally, we design a Marine Web GUI system of Kosrae Coastal Waters integrating above data models. It must adds more ecological information and the various service item for approach more easily in order to user.

Examination with medical radiography is the most significant advances in medicine in the 21st century. Diagnostic imaging occupies an important position in all medical subjects, surgical and internal medicine, including radiology, orthopedics, and neurosurgery. However, the invention associated with conventional radiography devices has focused only on emphasizing the efficient aspects of the examination or obtaining clearer images without considering the age and disease-induced constraints of the patient's posture. The newly developed X-ray aids to solve this problem can effectively perform X-ray imaging of children's who have difficulty communicating and controlling. It is also thought to be a good way to provide accurate imaging information and minimize radiation exposure for children.

A smart dust monitoring system is useful for obtaining information on rough terrain that is difficult for humans to access. One of ways to deploy sensors to gather information in smart dust environment is to use an aircraft in the Amazon rainforest to scatter an enormous amount of small and cheap sensors (or smart dust devices), or to use an unmanned spacecraft to throw the sensors on the moon's surface. However, scattering an enormous amount of smart dust devices creates the difficulty of managing such devices as they can be scattered into inaccessible areas, and also causes problems such as bottlenecks, device failure, and high/low density of devices. Of the various problems that may occur in the smart dust environment, this paper is focused on solving the bottleneck problem. To address this, we propose and construct a three-layered hierarchical smart dust monitoring system that includes relay dust devices (RDDs). An RDD is a smart dust device with relatively higher computing/communicating power than a normal smart dust device. RDDs play a crucial role in reducing traffic load for the system. To validate the proposed system, we use climate data obtained from authorized portals to compare the system with other systems (i.e., non-hierarchical system and simple hierarchical system). Through this comparison, we determined that the transmission processing time is reduced by 49%-50% compared to other systems, and the maximum number of connectable devices can be increased by 16-32 times without compromising the system's operations.

We report a case of a patient with cystic subdural hygroma who underwent pre-operative Tc-99m DTPA cistrenoscintigraphy to determine the course of operation. A 68-year-old female was admitted to the department of neurosurgery because of acute subarachnoid hemorrhage. After emergency ventricular drainage, the hydrocephalus and cystic subdural hygroma in the right fronto-temporal area developed. She underwent Tc-99m DTPA cisternoscintigraphy to evaluate the type of hydrocephalus, which revealed obstructive communicating hydrocephalus and the communication between the subdural hygroma and the subarachnoid space. As a result of these findings, she underwent the ventriculo-peritoneal shunt operation without removal of the subdural hygroma. Post-operative brain CT showed nearly normalized shape and size of the right ventricle and disappearance of subdural hygroma. We recommend the pre-operative cisternoscintigraphy in patients with complex hygroma to evaluate the communication between subdural hygroma and the subarachnoid space.
