  • 골프경기에서 상금이나 평균타수와 같은 척도에는 명확한 기록이 정의되어 있지만 누가 우승을 할 것인가 하는 관점에서는 Tiger Woods나 Phil Mickelson 그리고 Steve Stricker 등 2009년에 3승 이상을 한 선수를 제외하면 과연 누구일까 하는 의문을 갖게 될 것이다. 왜냐하면 워낙 선수층이 두터워 백지한창 차이의 실력을 갖춘 우승후보 선수들이 많고, 다른 종목보다 정신력이 결과에 많은 영향을 미치기 때문이다. 본 연구에서는 복잡한 비선형 형태의 자료를 파악하는데 아주 유용한 도구인 신경망을 이용하여 2009년 PGA자료를 바탕으로 우승자 예측모형에 대하여 연구를 하였다.

  • Recently, the ground-based laser profiler is used for acquisition of 3D spatial information of a rchaeological objects. However, it is very difficult to measure complicated objects, because of a relatively low-resolution. On the other hand, texture mapping can be a solution to complement the low resolution, and to generate 3D model with higher fidelity. But, a huge cost is required for the construction of textured 3D model, because huge labor is demanded, and the work depends on editor's experiences and skills . Moreover, the accuracy of data would be lost during the editing works. In this research, using the laser profiler and a non-calibrated digital camera, a method is proposed for the automatic generation of 3D model by integrating these data. At first, region segmentation is applied to laser range data to extract geometric features of an object in the laser range data. Various information such as normal vectors of planes, distances from a sensor and a sun-direction are used in this processing. Next, an image segmentation is also applied to the digital camera images, which include the same object. Then, geometrical relations are determined by corresponding the features extracted in the laser range data and digital camera’ images. By projecting digital camera image onto the surface data reconstructed from laser range image, the 3D texture model was generated automatically.

  • The effective management of R&D employees is critical for a small or medium sized firm's sustainable growth. R&D employees have professional skills and choose expertise-oriented or management-oriented careers in the process of organizational socialization. This study synthetically verifies the direct and indirect effects of R&D employees' social network and self-esteem on their career orientation by organizational commitment based on social network theory and social recognition theory. The research model has been analyzed through structural equation modeling using survey responses from 220 R&D employees at small- and medium-sized firms in Korea. The analysis results show that internal network activities have direct and indirect impacts on organizational commitment and career orientation, but external network activities do not have significant effects on self-esteem, organizational commitment, or career orientation. There is no consensus in prior studies on whether expert orientation and management orientation are distinct concepts. In this study, these two types of orientation are verified as distinct concepts. It is also found that R&D employees' internal network activities are significant factors for a company's growth. A company should implement an educational system of roles and duties using which individuals can pursue career progression. In addition, it is necessary to provide career development programs such as job rotation, mentoring, and career counseling.

  • TOF(Time of Flight) 기술은 물체의 3차원 깊이 정보 추출을 가능케 하는 기술 중의 하나이다. 하지만, TOF의 카메라의 출력인 깊이 영상을 이용한 물체의 3차원 위치 추출은 몸이나 손 등 크기가 큰 물체의 경우에는 비교적 신뢰성 있는 결과를 얻을 수 있는데 비하여 크기가 작은 손 끝의 경우에는 신뢰할 수 있는 값을 얻기 힘들다. 본 논문에서는 TOF 카메라에서 육면체 손 모델을 이용하여 수정된 손의 영상에서의 위치 정보와 팔 모델을 이용하여 손 끝의 3차원 좌표를 추정한다. 제안된 방법으로 실험을 한 결과 TOF 카메라의 깊이 영상만을 사용하여 인식한 손 끝의 3차원 위치정보와 비교하여 훨씬 더 향상된 결과를 얻을 수 있었다.

  • This paper presents a new colonoscopy training simulator that includes a specialized haptic device and graphics algorithms to transfer haptic sensation through a long and flexible tube, and manage large number of polygons. The developed haptic device makes the colonoscope tube move along the two guiding rods in the translational direction. The torque of the roll motion is transferred by a timing belt and pulleys. A special guide is developed, which allows the force and torque from the motors to be transmitted to the user without loss. The haptic device is evaluated by physicians. One of the important skills of the colonoscopy, jiggling is incorporated for the first time by the developed sensor mechanism using photo-sensors. A colonoscope handle that shares the look, feel, and functions with the actual colonoscope, is developed with the necessary electronics inside. The number of polygons is reduced by an edge-collapse algorithm for real-time simulation. The algorithms to import CT data, to segment the colon image, to extract centerline of the colon, and to construct the colon surface, are integrated into a Colon Modeling Kit system that performs all these processes in real-time.

  • The purpose of this study is to identify various predictors of smoking behavior among female adolescents. Data for this study was collected from 357 students enrolled in a female high school, a coeducational high school, and a vocational high school in Seoul from 1st to 20th July 1999 and this data was analysed based on descriptive statistics and logistic regression with the SAS program. The results were as follows: 1. The proportion of current smokers was 17.9% and experienced smokers was 34.2% in girl high schools. 2. According to the factors family, school, peer, social learning, and psychological factors, the predictable variables are lack of family attachment and function in family factors, school involvement in school factors, associating with smokers among peers and modeling and differential reinforcement of smoking in social learning factors, self-assertiveness, self-esteem, and depression in psychological factors. 3. According to all the factors, the main predictors were peer association, differential reinforcement of smoking, and lack of family attachment. These variables cause 48.4% of smoking behavior. To prohibit smoking among female students, this society should develop a program to focus on peer leadership about quitting smoking, acquirement of skills of refusal for smoking, counter conditioning, reinforcement management, and support system about nonsmoking.

  • 시험 불안은 인지적인 worry와 정서적인 emotionality 2요소를 갖고 있으며 상황에 특정한 인격 성향으로 정의되어 왔다. 정서적, 인지적 요소를 수정하려는 정도에 있어서 여러 치료가 다르고, 여러 치료가 치료적 기술의 영향이 예상된 궤적에 근거해서 인지-정서 연속선상에 따라서 놓여질 수 있게 되었다. 인지-정서 연속선상에 놓여진 여러 치료들과 학습 습관, 시험 치루는 기술과 모델링등이 검토되었다. 최근 시험 불안 치료 연구를 고찰하여 본 결과, 대부분 인지적 치료가 정서적 치료보다 시험 불안을 감소시키고 worry와 emotionality를 감소시키는데 더 효과적이라는 것이다.

  • This research investigates the relationship among product quality, service quality, perceived value, customer satisfaction, and behavior intentions. Validated measurements were identified from a literature review. The measurement model and the conceptual model depicting hypothesized relationships were evaluated based on responses from 220 customers using confirmatory factor analysis and structural equation modeling. The testing results show that, for the direct path, product quality has a significant, positive influence on customer satisfaction, and behavioral intentions. Also, perceived value directly influences customer satisfaction and behavioral intentions and satisfaction is an antecedent of behavioral intentions. For the indirect path, service quality has a significant, positive influence on behavioral intentions through the customer satisfaction. The major finding of this study suggest that service quality easily attract more customers, especially the young consumers. About the sale personnel, communication skills, knowledge and ways of treatment to customers are crucial to retailers to gain competitive advantage over competitors. Therefore, it should have clear and consistent processes, procedures with criteria that create the best condition for organization and individual to open this kind of retailing store. Furthermore, product quality improvement is essential; all products must have clear originality; and diversifying products and services is also the way to appeal more consumers.
