The Korean government has been promoting the establishment of comprehensive information systems as one of supports for preschools' administration. This support is expected to enhance the efficiency of preschool education support systems and to improve the quality of educational services. The gap between government's expectation on an introduction of the information system and preschool educators' expectations has also been an issue in deploying this new system. This study identifies user resistance factors for comprehensive preschool administration assistance systems' deployment. We find that the performance expectancy, social influence, effort expectancy, and the psychological cost of user resistance have impacts on the user resistance. When these factors related resistance are resolved in the process of systems' deployment, active participation in these systems by preschool educators would be increased.

Most of flood protection walls built on the impingement in mountain rivers have been made of concrete. It may cause flood disasters because the smooth wall surface could increase flow velocity. In this study the hydraulic experiments was carried out to evaluate the effect of one side wall with rectangular vertical ribs on flow resistance in open channel. The ratio of the pitch between vertical ribs to its depth, ${\lambda}_{nv}$, was designed so that it include the so-called d type and k type roughness. The range of Froude number, $F_r$, based on hydraulic radius is 0.81~1.12. Flow resistance in the open channel with a rib sidewall depends on the interval length of each ribs and the flow discharge. Maximum flow resistance occurred when ${\lambda}_{nv}$ is 9. In the d type roughness which ${\lambda}_{nv}$ is less than 3, the flow resistance decreases with increase of flow discharge. In the k type roughness which ${\lambda}_{nv}$ is greater than 3, the flow resistance increases with increase of flow discharge. The increments of flow resistance are especially great when ${\lambda}_{nv}$ are 9 and 12. The resistance due to vertical rib is mostly by the shape resistance and the vertical rib on one sidewall of open channel affects on the flow resistance so that the equivalent roughness heights of vertical rib may occur in scale of flow depth. Therefore the vertical ribs may be used to reduce the flow velocity and to move the location of maximum flow velocity from the rib sidewall to the centerward in a cross section of channels.

Schedule-based public transit routing algorithm computes a single route that calculated minimum travel time using the departure and arrival times for each stop according to vehicle operation plan. However, additional factors such as transfer resistance and alternative route choice are not reflected in the path finding process. Therefore, this paper proposes a improved RAPTOR that reflected transfer resistance and multi-path searching. Transfer resistance is applied at the time of transfer and different values can be set according to type of transit mode. In this study, we analyzed the algorithm's before and after results compared with actual route of passengers. It is confirmed that the proposed algorithm reflects the various route selection criteria of passengers.

식민지하 동남아 천년왕국 운동에 대한 오늘날의 해석들은 그 주체인 농민들을 식민주의를 개념화하고 저항하는 동기와 조건 그리고 상징을 제공하는 토착 지식의 전수자로 간주한다. 종말론과 저항에 대한 관심의 대부분은 농민연구나 지역연구 학자들로부터 유래하며, 이들은 봉기에 대한 과거의 묘사들이 토착의 정신세계를 간과했거나 국가이념을 저항세력들의 결집원리로 과대 포장한 것에 주의를 기울인다. 천년왕국 봉기에 관한 글들에서 제공하는 해석들은 동남아 신념 체계에 관한 독립적인 관점을 제공할 뿐만 아니라, 인식론적 측면에서 식민지국가들을 이와 같은 전통에서 단절시키고 있다. 영국 식민지하에서 최대의 농민반란인 서야쌍 봉기(1930-1932)는 오늘날 이와 같은 천년왕국 운동의 정수를 보여주는 사례로 간주된다. 학자들은 수천 명의 농민들로 하여금 버마인의 권위를 되찾고, 불교를 회복시키며, 식민통치로 인해 낳은 사회-경제적 부조리를 일소시킬 그들의 왕으로 믿게 만든 한 농부의 흥미로운 이야기를 묘사하고 있다. 일련의 반란이 미신에 의해 추동되었다고 간주한 식민지 관찰자들과는 달리 이후의 역사가들은 그 반란이 불교를 재건하고 태평성대로 인도할 미래부처인 미륵불의 현신에 대한 믿음의 표현이라고 해석했다. 이러한 학자들에게 서야쌍 봉기는 어떻게 동남아 사람들의 감수성이 식민지의 사회-경제적 압력 속에서도 지속되었으며, 상좌불교의 예언이 토착의 문화적 토양에 얼마나 깊이 내재해 있는지를 말해주는 사례였다. 경험적 관점에서 본 글은 서야쌍 봉기의 근원을 재해석함으로써 천년왕국 봉기에 관한 글들이 대부분 식민지적 문서화 작업과 종교를 과장되고 세속화된 화술로 믿게 하려고 지역연구자들의 산물임을 밝히고 있다. 개념적 관점에서 본고는 버마에서 일어난 천년왕국 운동의 역사적 구성에 대한 식민주의의 역할을 보다 면밀히 관찰하였다. 또한 식민지법, 학문, 그리고 식민지하 버마 농촌에서 발생한 종교적 저항에 대한 우리들의 이해를 상호 연결하는 인식론적 관계를 탐구했다. 그리하여 본고는 천년왕국 해석이 이 시기에 공존했던 다른 유형의 불교정치적 형태를 어떻게 왜곡했는가를 밝히고 있다.

The purpose of this study is to investigate the relationship between vertical leadership and shared leadership, organizational trust and innovation resistance. For this purpose, a regression analysis was conducted based on data from 286 questionnaires completed by employees working in IT companies. As a result of the analysis, both shared leadership and vertical leadership showed a negative relationship with innovation resistance. For organizational trust, it was confirmed that there was a mediating effect in the relationship with innovation resistance. Shared leadership seems to form a stronger negative relationship with innovation resistance than vertical leadership, it was found that shared leadership is more effective in lowering innovation resistance. Therefore, if the strengths of vertical leadership and shared leadership are applied complementary to each other on the basis of organizational trust in promoting innovation, it will be a good way to overcome innovation resistance, which is a barrier to innovation success. To overcome innovation resistance, especially in IT startups, we propose the complementary application of vertical leadership and shared leadership based on organizational trust.

The purpose of this study was to compare the effect of changing the order of exercise types on body composition and blood lipid in obese women. The subjects were 40-years obese women. They were trained during the 12 weeks by combined exercise program which included aerobic and resistant exercises. 1. In the cases of weight, A group(aerobics and resistance training)more decreased than B group(resistance training and aerobics). There was not statistically significant difference before and after 12-week combined exercise program between the groups. In the case of body fat mass, A group more decreased than B group. There was a statistically significant difference between the groups(p<0.01). Lean body mass, A group more increased than B group but there was a statistically significant difference between the groups. A and B groups were decreased in abdominal percent fat and there was a not statistically significant difference between the groups. 2. There were not any significant differences between two groups after 12-week combined exercise program at total cholesterol(TC), triglyceride, and high density lipo-protein(HDL) cholesterol. 3. In the case of blood glucose, group A showed more decreased than group B after 12-week combined exercise program. The difference before and after exercise program of A and B groups was statistically significant(p<0.01). In conclusion, the combined training which include resistant and aerobic exercise may use selectively to induce change of body composition and blood lipid for weight loss in 40-aged obese wome

This study aimed to investigate the effects of scaffolding on creativity in Wiki-based collaborative learning. Wiki-based collaborative learning was implemented over three sessions among 67 sixth graders in an elementary school, and subjects were divided into three groups: Group 1 had a teachers' scaffolding and self-questioning script; Group 2 had a teachers' scaffolding; and Group 3, the control group, had no scaffolding. Results showed a significant difference in creativity among the groups with different types of scaffolding(Wilks' Lambda=.238, F=8.678, p < .001). Group 1, had significantly higher performance compared to the Group in creativity. However, when self-questoning script and a teachers' scaffolding were offered, self-scaffolding was not found to have a significant effect on learners' Originality of creativity. Group 2 showed higher performance in Originality of creativity when only a teachers' scaffolding was offered in the collaborative learning. The results of this study suggest that teachers' scaffolding and self-scaffolding have positive effects on creativity, but the need for a differentiated self-scaffolding strategy to identify the factors that influence creativity in wiki-based collaborative learning.

This study investigeted secondary math teachers' difficulties of technology in geometry class with grounded theory by Strauss and Corbin. 178 secondary math teachers attending the professional development program on technology-based geometry teaching at eight locations in January 2014, participated in this study with informed consents. Data was collected with an open-ended questionnaire survey. In line with grounded theory, open, axial and selective coding were applied to data analysis. According to the results of this study, teachers were found to experience resistance in using technology due to new learning and changes, with knowledge and awareness of technology effectively interacting to lessen such resistance. In using technology, teachers were found to go through the 'access-resistance-unaccepted use-acceptance' stages. Teachers having difficulties in using technology included the following four types: 'inaccessible, denial of acceptance, discontinuation of use, and acceptance 'These findings suggest novel perspectives towards teachers having difficulties in using technology, providing implications for teachers' professional development.
