A new algorithm for speech signal segmentation is proposed. This algorithm is based on finding successive similar frames belonging to a segment and represents it by an average spectrum. The speech signal is a slowly time varying signal in the sense that, when examined over a sufficiently short period of time (between 10 and 100 ms), its characteristics are fairly stationary. Generally this approach is based on finding these fairly stationary periods. Advantages of the. algorithm are accurate border decision of segments and simple computation. The automatic segmentations using frame averaging show as much as $82.20\%$ coincided with manually verified segmentation of CMU ARCTIC corpus within time range 16 ms. More than $90\%$ segment boundaries are coincided within a range of 32 ms. Also it can be combined with many types of automatic segmentations (HMM based, acoustic cues or feature based etc.).

The mumps virus is a single-stranded, non-segmented, negative-sense RNA virus belonging to the $Paramyxoviridae$ family. Mumps is characterized by bilateral or unilateral swelling of the parotid gland. Aseptic meningitis is a common complication, and orchitis is also common in adolescents and adult men. Diagnosis is based on clinical findings, but because of high vaccination coverage, clinical findings alone are not sufficient for diagnosis, and laboratory confirmation is needed. Mumps is preventable by vaccination, but despite high vaccination coverage, epidemics occur in several countries, including Korea. Many hypotheses are suggested for these phenomena. In this review, we investigate the reason for the epidemics, optimal methods of diagnosis, and surveillance of immunization status for the prevention of future epidemics.

The aim of the current study was to suggest priorities needed to be considered by university instructors when designing online learning. Based on three types of interactions (learner-content, learner-instructor, and learner-learner interactions) for effective online learning (Moore, 1989), draft questionnaires representing each type of interaction were written. After examining content validity by two Ph.D. experts, the survey was constructed with an Importance-Performance Analysis (IPA) form. Data of 133 university instructors were collected online. Results showed that support for designing learner-learner interaction was the priority for improving online learning. In terms of learner-instructor interaction, instructors needed to provide social-emotional support to learners so that learners could have a sense of belonging. For learner-instructor interaction, supporting instructors to monitor the level of understanding was the most highly demanding strategy for online learning. Limitations and suggestions for further studies were discussed.

Purpose .This study aims to assess the influence factors on the level of satisfaction with hospital training and to provide basic data for more efficient hospital practice of students' public health administration . Methods . We have conducted a survey on students satisfaction with their hands on practice against 200 students in Busan, Kyeongnam and Kyungbook area, who have completed their practice in public health administration. We have identified the general characteristics of the target respondents, the current training status of the department for the hospital practice and training venue; also analyzed the characteristics composed of the apprentice student's attitude before the practice, satisfaction with the department training program and hospital for practice, as well as their practice at hospital. The general characteristics of the target respondents and clinic practice status at the hospital were measured in percentage and frequency analysis; the average and standard deviations of hospital size were also measured; and the correlations between satisfaction with the department, attitude towards the practice and satisfaction with the hospital were analyzed. Results . Most public health administration students experienced their practice at the hospital after the first semester on the $2^{nd}$year and they have received the foundation training for the practice. The survey allowed multiple responses and the results are as follows: medical terminology 49.5%, medical coordinator 36.7%, Hospital administration 26.5%, Health insurance 17.3%, and medical recording and practice 13.8% respectively. In terms of each individual student's attitude towards the practice at the hospital, the respondents answered as follows: I have completed the obligatory subjects for the practice before the practice 89.5%; I have been fully informed on the hospital for my practice. 74.5%; I responsibly practiced and worked with professionalism and sense of belonging to the hospital as a member of staff 90%; I have actively learned and adopted 95%; My knowledge and skills from the practice was relevant to the theory and practice from my course 83.5%. The findings of satisfaction by size of hospital were in order of a small clinic($3.24{\pm}0.63$), medium sized clinic($3.27{\pm}0.65$), hospital ($3.20{\pm}0.61$), and large sized comprehensive hospital ($2.93{\pm}0.74$). Consequently the satisfaction rate shows no significant difference by size of hospital. In relations between practice attitude and satisfaction with subject, the matter of acquiring information and fully understanding of the hospital for practice before practice(p=0.04), the matter of a sense of belonging and responsibility at hospital during practice(p=0.33). the matter of active adaptation attitude during practice (p=0.42), and the matter of correlations with school curriculum during practice(p=0.00) showed significant results. In relations between practice attitude and satisfaction with the hospital for practice, the matter of acquiring information and fully understanding of the hospital for practice before practice(p=0.01), the matter of a sense of belonging and responsibility at hospital during practice(p=0.04), and the matter of correlations with school curriculum during practice(p=0.00) showed significant results. Conclusion . The most essential subject for the practice in public health administration is medical terminology and there is no significance in satisfaction with the practice by size of hospital. Students were content with the hospital where they can experience as much as possible. Students content with their major show positive attitude towards the practice and so do those content with the hospital. Those with the positive attitude towards the practice show the high correlation of satisfaction with both the major and hospital. As a result, the satisfaction with the major is the significant attribute to the practice in the hospital.

이 글은 1970년대 한국 영화에 재현된 타자들의 존재 방식에 대해 분석했다. 당대의 사회 변화들, 가령 급속한 산업 근대화로 인한 도시화 속에서 수많은 사람들이 근대화의 열매를 얻기 위해 산업 역군으로서의 주체 구성을 해 나갔지만, 이러한 주체 구성의 과정에서 필연적으로 양산되었던 타자들의 풍경은 그동안 젠더 및 청년 담론 속에서 제한적으로 분석되어 왔다. 이러한 점에 착안하여 이 글은 시각을 달리하여 1970년대적 타자들의 풍경을 추출해내는 데 목적을 두었다. 타자들의 존재 방식은 다음의 두 가지 구분 속에서 발견할 수 있다. 첫째, 1970년대 영화에서 가족 공동체는 1960년대의 그것과는 달리 해체되고 균열된 상태로 존재하는데, 이는 타자들이 그 공동체에 진입할 수 없거나 이탈함으로써 발생한다. 가족 공동체는 더 이상 주체 구성의 안정된 토대 혹은 구심점으로 작용하지 못하는데, 안정감과 소속감을 가질 수 없다는 공동체에 대한 절망적 인식은 공동체 안팎을 배회하는 타자들의 존재 방식을 통해 잘 드러난다. 둘째, '죽음'은 1970년대 국가 이데올로기의 폭력과 일상화된 예외 상태 속에서 사회적 삶의 한 양태를 보여 주는 요소이다. 국가가 요청한 정상적 주체성에서 완벽하게 배제되고 추방된 타자들이 영화 안에서 죽는 방식은 일상화된 죽음 혹은 잠재적 죽음의 상태가 1970년대의 삶이라는 점을 보여 준다. 급격한 도시화와 산업화를 통해 추구된 정상적 삶은 타자화된 존재들을 죽음에 이르도록 하지만, 실제 타자들의 존재 방식은 안정감과 소속감을 부여하는 국가의 경계를 무너뜨리고 삶과 죽음의 경계가 무색해진 1970년대 절망적 현실을 고발하는 것이다. 결과적으로 1970년대 타자들의 풍경은 1970년대 산업 근대화가 그토록 지향했던 완벽한 중산층 가족 담론을 파괴하고 그것이 오히려 수많은 죽음을 초래하는 타자들을 양산하는 폭력적 현실을 드러낸다. 한국영화는 정권의 검열에도 불구하고, 재현의 우회로를 따라 1970년대가 가져온 삶의 폭력성을 대중적으로 폭로하고 있었던 것이다.

The principal objective of this study was to analyze Swede's perceptions of Asian food using a means-end chain method, which may contribute to our understanding of new markets for a food industry interested in globalizing Korean food. With the Means-end chain method, one can determine the cognitive structures built in consumer's minds, which are developed by connecting attributes of product, consequences, and values. The attributes of Asian food that are most positively perceived by Swedes are 'fresh vegetables', 'low-fat', 'light meat and seafood', 'exotic ingredients', 'not expensive' and 'unknown food'. The consequences of eating Asian food connected to these attributes are 'healthy', 'tasty', 'good way to save money' and 'curious'. Finally, Swedes expect to enjoy a value of 'achievement' at the end. Based on the result that 'unknown food' attribute is connected to 'achievement' value, Swedes are assumed to be attracted by the fact that Korean food is 'unknown food'. However, the effect of the 'unknown food' attribute will fade away with time; therefore, stressing Korean food's status as a 'healthy' food, which can be attributed to its use of 'fresh vegetable' and 'light meat and seafood' ingredients and 'low fat' cooking method may be effective as a long-term strategy for making Korean food attractive. The 'healthy' consequence is connected to Swedes' perception of the value 'achievement' and simultaneously to their perception of the value 'belonging and love/sense of belonging'.

Objectives : The purpose of this study was to measure the effect of factors analyes the associated by the dental treatment fear of level dental hygiene and non-dental hygiene students, and then to provide basic material which can help to improveoral health and effective dental treatment. Methods : The subject in this study were 275 students in Jeolla region. The data were collected from March through April 2010, by way of the self-reported questionnaire. Results : 1. Subjects, who correspond to 'high fear level' which is more than 60 points in the scale of Dental Fear Survey, were indicated to be larger in collegians of general-related departments(38.9%) than collegians of health-related department(36.3%).2. Among three detailed factors, the treatment-stimulator response factor showed the higher fear sense than other 2 factors. In the physiological response, 'muscular tension' was 2.72 points, there by having been indicated to be the highest.3. The more belonging to the group with high fear was indicated to lead to the more in direct pain experience, in non-anesthesia pain experience, and in indirect pain experience through brothers and sisters. Even the symptom and syndrome in oral disease were indicated to be much. 4. As a result of comparing difference in dental fear level depending on pain experience, it was indicated that the more belonging to the group with high fear leads to the more in direct pain experience, in non-anesthesia pain experience, and in indirect pain experience through brothers and sisters. Conclusions : Dental fear must be controlled carefully in order to promote oral health and effective dental treatment.
