본 논문에서는 SGR(software-based Global Positioning System receiver)에서 GPS(Global Positioning System)의 자료처리과정을 분석하기 위해서, GPS 신호의 수신방법을 심도있게 분석했다. 그리고 이 처리과정을 Matlab를 사용해서 모의실험을 했다. 실험결과, 이 분석방법의 타당성을 찾을 수 있었고, 이 실험은 실제 환경조건에서와 일치함을 확인할 수 있었다. 또 SGR의 성능을 향상시키기 위해서는 수신기의 성능을 향상시켜야 한다는 사실을 확인 할 수 있었는데, 동조되는 최적의 주파수는 수십 Hertz내에서 위상을 비교해서 찾을 수 있었다.

Because a logo is a medium that connects between consumers and corporations or brands, designing memorable logo images is vital. Although predicting logo's memorability for brand marketing is essential, there have been only few researches that deal with memorability of logo images. In this paper, we analyze the memorability characteristics in logo images by performing experiments based upon our proposed prediction method for logo image's memorability. Our proposed research consists of three phases: crowdsourcing for memorability computing, computational phase for logo image's memorability, and development of a prediction model. Using computed memorability of logo images by "Visual Memory Game," we analyze the different characteristics of logo's memorability. We first developed a novel computational method that reflects logo image's color and shape. Each computational method on color and shape are selected by comparing the correlations between result values and ground truth memorability. Selected computational value is then converged with generic image feature descriptors such as SIFT and HoG to make a prediction model of logo's memorability. Using our method, we obtain reasonable performances in predicting logo image's memorability.

Cystic hygroma, a cystic subtype of lymphangioma, is relatively rare tumor of lymphatic origin. The lesion is a benign, painless, soft, compressible malformation of the lymphatic system. They can arise anywhere along the lymphatic system, however they are usually located in the head and neck regions and in most cases appear by the age of 2 years. The cases in the adult is rarely occurred and a few cases are described in the literature. Surgical excision remains the treatment of choice. But complete extirpation of these lesion is often impossible, because the tumor tends to spread along vital structures. Therefore recurrence rates are accordingly high. This is a case report about 19 year old male patient with cystic hygro a on right retromandibular area. We obtained the successful, functional and esthetic result by surgical excision of the mass. Therefore, we report the case with a review of literatures.

음의 생성은 성문하의 기류가 성대에서 조절되고 성대상부의 Vocal tract에서 modulation되어 생성되므로 후두에 이상이 생기면 발성시 후두를 통과하는 기류에 변화가 오게된다. 타국에서는 Dohne(1944)과 Arnold(1955, 1958)등 여러학자들이 후두질환에 따른 공기역학적 변화를 측정하여 후두질환의 진단에 기여한 바 크다. 본 저자들은 후두질환에 따른 공기역학적 측정에 앞서 이에 대한 정상역치를 측정하여 그 기준치로 하고자 21∼30세의 정상인 남녀 각각 20명을 대상으로 Collins회사제 Respirometer를 이용하여 평균 기류유출률, 최대 밭성량, 최대발성시간 및 발성속력치 등을 측정하였기에 제 1보로서 보고하는 바이다.

Livestock is considered as one of the most important segments in agriculture since animal husbandry was practiced for centuries as a backyard system by rural families. Livestock plays as a powerful tool in rural development where meat industry contributes a dominant part. Meat and meat products become a vital component in the diet, which had been one of the main protein sources traditionally as well. The development in the livestock and meat industry of Sri Lanka basically depends upon religious, cultural, and economic factors. There is a growing demand for processed meat products in Sri Lankan urban culture and several large scale processors entered the business during the past few decades. The consumption of meat and meat products shows an upward trend in Sri Lanka during the last decade and is anticipated to increase further in future. The growth potential of the local meat industry is considerably high owing to the improvement of the market and consumer perception. The present status, trends, and future prospects for the Sri Lankan meat industry with respect to production, consumption, processing, marketing, and improvement are discussed in this review.

The objective of this research was to identify the factors that affects the customer's satisfaction and dissatisfaction of theme parks. This research focused on Sunway Lagoon. The reason Sunway Lagoon was selected was because of the vast number of visitors in Sunway Lagoon for the last few years. It enables the researchers to acquire sufficient amount of information to conduct a research. The factors which affects the customers' satisfaction are the behavior of the generation Y; service experience evaluation, perceived price, emotions, and servicescape. The limitation of this research was inadequate time to perform in-depth investigation on the research. The research study implemented qualitative research, thus the interview was used as a data collection. Since Sunway Lagoon was selected as the research setting, the face-to-face interview with 10 participants was conducted in the setting. This research is vital because it enables the organizations to determine factors that influence the customer's satisfaction and future behavioral intentions. As a result, organizations are able to achieve higher levels of customer satisfaction as well as promoting customer loyalty.

Fractures of the styloid process of the temporal bone may occur with or without an obvious relation to trauma. The incidence of either isolated styloid process fracture or in combination with mandibular fractures is rare, and such occurrences are often misdiagnosed or neglected. A fractured styloid when displaced may impinge on adjacent vital structures, leading to neurological or vascular symptoms that vary according to the anatomical structure compressed. Styloid process fractures associated with atlas/C1 fractures have also been rarely reported in the literature. In this review of literature, the majority of patients was treated conservatively, as few demonstrated the necessity of surgical intervention. There is a definitive need for a protocol to recognize and classify styloid fractures to plan for further treatment. The aim of this review was to achieve a comprehensive understanding of all types of styloid fractures, determine the clinical severity of symptoms, and to consider management and prognosis. In addition, a new classification of cervico-stylo-mandibular fractures is proposed based on important evidence in the literature regarding clinical and radiographic factors that might influence the treatment and prognosis of such fractures.

Faculty advisors play a vital role in a learning and adjustment process of doctoral students at their work, department, university and discipline by sharing and exchanging relevant information and knowledge in the profession. Despite the important role of information practice in doctoral advising, few studies have investigated the informational aspects of faculty advisors and their students. Thus, this study aims to consider the distribution of information exchanged between faculty advisors and their doctoral students and relate them to doctoral students' demographic characteristics (gender, age, race and/or ethnicity, degree, and stage of doctoral work). The findings of this study show that overall information exchange is most frequent at the work level followed by the discipline, school/department, and university levels. In particular, information exchange at the work and discipline levels explains the characteristics of doctoral education, socializing students into both student and professional roles. In addition, there are statistically significant differences in information exchange along certain dimensions according to the advisee's gender, age, race and/or ethnicity, degree, and stage of doctoral study, suggesting that information needs and seeking behavior may vary according to the demographic characteristics of advisees.
