A single subject experimental design (alternating treatment design) was used to compare the effects of Mulligan method and electrotherapy on the pain and limitation of range of motion in patients with frozen shoulder. In the Mulligan method sessions, the physiotherapist performed a posterior and caudal glide on the patient while the patient was performing shoulder flexion and abduction. In the electrotherapy sessions, the patient received ultrasound and interference current treatments. Mulligan method and electrotherapy were alternately performed on each patient. Pain was measured by visual analogue scale (VAS) and range of motion (ROM) was measured by modified finger ladder. The results showed that both Mulligan method and electrotherapy were effective in pain reduce and ROM increase, but Mulligan method was superior to electrotherapy in ROM increase while electrotherapy was superior to Mulligan method in pain reduce.

Pierre Robin syndrome is characterized by micrognathia, glossoptosis, and cleft palate. Infants with Pierre Robin syndrome causes feeding difficulty, upper airway obstruction, and other symptoms. This study aims to examine the effects of applying dysphagia treatment to infants with Pierre Robin syndrome. The study participant was an infant who was born four weeks premature and referred for dysphagia treatment approximately 100 days after birth. At the initial assessment, the infant showed oral sensory sensitivity, a high level of facial and masticatory muscle tension, and a low stability of the chin and cheeks with almost no normal "sucking-swallowing-breathing" pattern. We set the baseline period and intervention period using the AB design. During the baseline period, non-nutritive sucking training using a rubber nipple was conducted without implementing an oral stimulation intervention. During the intervention period, non-nutritive sucking training and an oral stimulation intervention were performed. After the intervention period, the infant's daily oral intake and oral intake per time significantly increased compared to that during the baseline period. We observed that the oral intake time of the infant decreased during the intervention period compared to that in the baseline period, which indicated an improvement in control over the chin, tongue, and lip movements, a change in muscular tension, and stabilization of the "sucking-swallowing-breathing" pattern. We provided dysphagia treatment before breastfeeding, it was positive effects such as normal development of the infant, transition from tube feeding to bottle feeding, and enhancement of overall oral motor function.

The study of bacterial flagellar swimming motion remains an interesting and challenging research subject in the fields of hydrodynamics and bio-locomotion. This swimming motion is characterized by very low Reynolds numbers, which is unique and time reversible. In particular, the effect of rotation of helical flagella of bacterium on swimming motion requires detailed multi-disciplinary analysis. Clear understanding of such swimming motion will not only be beneficial for biologists but also to engineers interested in developing nanorobots mimicking bacterial swimming. In this paper, computational fluid dynamics (CFD) simulation of a three dimensional single flagellated bacteria has been developed and the fluid flow around the flagellum is investigated. CFD-based modeling studies were conducted to find the variables that affect the forward thrust experienced by the swimming bacterium. It is found that the propulsive force increases with increase in rotational velocity of flagellum and viscosity of surrounding fluid. It is also deduced from the study that the forward force depends on the geometry of helical flagella (directly proportional to square of the helical radius and inversely proportional to pitch).

최근에 이르러 뇌에 대한 연구가 체계적으로 이루어지고 있으며 뇌파를 활용하기 위한 Brain-Computer Interface(BCI) 기술에 대한 연구가 활발히 진행되고 있다. 특히, BCI 기기를 활용한 기능성 게임 기술이 관심의 대상이 되고 있다. 본 논문에서는 미국 뉴로 스카이사의 마인드셋 SDK(System Development Kit)를 이용하여 집중도과평정도에 따라 협동심과 사회성을 길러주는 기능성 게임으로 기존의 1인용 게임과 차별을 둔 "2인용 협동 댄스게임" 구현을 제안한다. 이 게임은 일반인의 뇌 활성화 및 ADHD 아동과 경도인지장애를 보이는 노인 치료에 도움을 주고 청소년들의 게임문화에 대한 사회적 순기능 역할을 할 것으로 기대한다.

If any of the set parameters such as the environment temperature, mold temperature are not maintained at a consistent level, the fail rate of injection molding products is increased. The price of the injection molding machine is very high, so in order to maximize the utilization of the machine that is required the production of a number of different products with minimum fail rate using a single machine. To prevent the defect products by an inspection process with perfect quality is very important to minimizing production of defect products in the molding process. Vision inspection systems are widely utilized in various manufacturing industries for quality assurance purposes. The vision inspection system consists of CCD camera and lighting system to capture the image of the subject of inspection, an image comparison algorithm using to determine the pass/fail of the products, and mechanical devices for the operation of the whole system. This research focuses on the development of the vision inspection system to process the inspection of an automobile parts. We developed a mechanical devices for the inspection of the injection molding products and an image comparison algorithm to determine the pass/fail result of the inspection based on the molding image and the accepted product image.

정보환경의 변화에 따라 도서관과 웹 검색엔진의 차별성이 있음에도 불구하고 이용자들은 인터넷의 자원과 학술데이터베이스의 자원을 혼동하고 있다. 특히 구글스칼라와 같은 상업용 검색엔진의 검색속도 와 조작 편의성이라는 상대적 장점 때문에 학술데이터베이스가 갖고 있는 학술적 가치와 신뢰성에도 불구하고 이용자는 구글스칼라를 선호하고 있는 실정이다. 이 연구에서는 구글스칼라가 갖는 장점을 반영한 메타서치시스템의 특성과 가치를 인터페이스 측면과 전자정보원 측면에서 분석하였다. 또한 이러한 새로운 검색채널로서 메타서치시스템과 이와 연계된 링크리졸버를 이용하는 대학도서관의 이용통계를 분석하였다. 이를 바탕으로 구글스칼라와 차별화될 수 있는 도서관만의 특징인 이용자 이용행태 패턴과 주제별 전자정보 이용행태를 도출하여 전자정보 서비스의 방안으로 활용할 수 있음을 조사하였다.

인간의 피부를 사실적으로 렌더링하는 것은 그 동안 컴퓨터 그래픽스 분야에서 난제로 여겨져 왔으며 지금까지도 중요한 연구 과제로서 남아있다. 피부와 같은 반투명성 물질은 표면하 산란을 포함한 복잡한 광학 특성을 가진다. 본 논문에서는 사실적인 피부 렌더링을 위해 표면하 산란을 고려한 쉐이더를 제안하고 3D 패키지, 마야의 플러그인 형태로 구현하였다. 구현된 피부 쉐이더를 적용한 렌더링 이미지는 기존의 전통적인 쉐이딩 기법을 이용한 이미지에 비해 보다 더 사실적인 피부의 표현이 가능하였고 피부의 피지, 표피, 진피 층을 각각 정반사, 다중 산란, 단일 산란으로 모델링할 수 있었다.

A single subject experimental design (alternating treatment design) was used to compare the effects of only ultrasound and ultrasound combined with stretching of the joint capsule on the ROM increase and pain reduction in patients with frozen shoulder. Two subjects were included in each group. In the only ultrasound treatment sessions, ultrasound was applied at the pain point of the shoulder joint in supine position. In the ultrasound combined with stretching treatment sessions, ultrasound was applied at the pain point of the shoulder joint positioned in external rotation and abduction in sitting position. Only ultrasound treatment and ultrasound combined with stretching treatment were alternately performed on each patient. Pain and disability was measured by shoulder pain and disability index (SPADI), and range of motion (ROM) was measured by scratch test. The results of this study showed that ultrasound combined with stretching treatment were more effective than only ultrasound treatment in ROM increase and pain reduction. However, disability score was not significantly different.

While the cognitive aspects of customer behavior have been a main subject of research, some researchers are now focusing on the emotional aspects. The influence of emotion on attitude and judgement has been accepted by many researchers, and most studies regarding emotion have focused on physical surroundings and emotional responses, based on Mehrabian & Russell's 1974 model. This study aimed to expand the scope of the model by including employee service. Here we examined the structural relationships between the physical surroundings and employee service of upscale restaurants, along with emotional response, and service loyalty. Physical surroundings and employee service were used as single factors, and we composed four different emotional responses: positive, negative, positive arousal, and negative arousal. While physical surroundings had impact on 'positive emotion' and 'positive arousal', Employee service had influence on 'negative emotion', and 'negative arousal' as well as 'positive emotion'. And 'positive emotion' and 'positive arousal' influenced service loyalty. Lastly, there was also a correlation between physical surroundings and employee service.
