본 연구는 보건계열 대학생을 대상으로 취업역량강화 프로그램 수행 후 만족도가 대학생활 적응과 학업성취도에 어떠한 영향이 있는지를 실증분석하기 위해 수행하였다. 충북 소재 1개 대학교의 보건계열 전공자를 대상으로 취업역량강화 프로그램 수행 후 만족도 및 대학생활 적응과 학업성취도를 자기기입식 설문조사를 통하여 수집하였다. 분석결과 취업역량강화 프로그램 만족도가 높을수록 대학생활 적응이 좋은 것으로 나타났으며, 높아진 대학생활 적응은 학업성취도에 영향을 미치게 됨을 알 수 있었다. 비록 취업역량강화 프로그램 만족도가 학업성취도에는 직접적인 영향관계가 없었으나 대학생활 적응을 통해 학업성취도가 높아져 향후 취업에도 긍정적인 영향이 있음을 시사한다. 대학 적응을 높이고 취업 활성화를 위한 환경 마련을 위해 학과 특성에 맞는 취업관련 프로그램을 활성화하는 적극적인 노력이 필요하다.

Capacitor-run single-phase induction motor is cheaper than motors that use permanent magnets and is widely used in home appliances and industries based on relatively high durability and productivity. It can also be operated by line. However speed cannot be controlled because the line frequency is free. In this paper we dealt pole change method one of the method controlling speed of capacitor-run single-phase induction motor. The conventional pole change method is difficult to improve the power and efficiency of the motor because the composition of the pole change device is complex and do not have enough area of the windings because of windings not used according to the driving conditions. In this paper, we proposed the pole change method that is used main windings and auxiliary windings at 4 poles operation and used auxiliary windings as compensation windings at 2 poles operation. The proposed method was verified through finite element analysis.

Recently Manipulation capability is important for a robot. Interaction between a robot hand and objects can be properly controlled only is suitable sensors are available. Recently the tendency is to create robot hands more compact and high integrated sensors system, in order to increase the grasping capability and in order to reduce cabling through the finger, the palm and the arm. As a matter of fact, miniaturization and cabling harness represents a significant limitation to the design of small sized embedded sensor. Ongoing work is focusing on a flexible manipulation system, which consists of a dual flexible multi-fingered hand-arm system, and a dual active vision system.

This Paper analyses characteristics of the numerical controller industry in market formation and the flow of information between users and producers and the characteristic of knowledge base of the industry and discusses the difficulties derived, from the characteristics, in accumulation of technological capability In market formation between users and producers, the multi-layered market is not favorable to domestic producers in that lower end market is not large enough to provide cradle market to them which produce inferior quality and lower price than imported products. The credibility of the performance of a product is difficult to prove until a critical mass of products are sold. Therefore gaining market share is deterred by unproven credibility of the performance of the product. The flow of information between users and producers is limited. The flow of information on users environment through mass market to producers is essential for improving credibility of a product. The nature of knowledge base is tacit and the means of knowledge transmission is limited. Technological licensing and reverse engineering, which have been conventional means of knowledge transmission, are not useful in the numerical controller industry. These characteristics provide conditions of vicious circle in accumulation of technological capability of the numerical controller industry. It is conjectured that these characteristics are derived from the fact that the numerical controller is the result of IT based technological convergence in controlling machining process. This paper argues that these characteristics of the industry challenges existing approach to R&D management and framework of science and technology Policy.

최근 정보통신기술의 발전에 따라 디지털 정보를 포함한 다양한 데이터들이 기하급수적으로 증가하였으며 이러한 데이터의 활용이 보편화된 최근의 사회는 수사와 재판과정에도 많은 변화를 주었다. 하지만 기하급수적으로 늘어나고 있는 디지털 증거에 대한 기술력과 분석력의 진보에 비해 디지털 포렌식 관련 법과 제도의 확립은 아직 부족한 실정이다. 그러므로 디지털 증거의 법적인정을 위해서는 균형 잡힌 연구의 활성화가 필요하다. 따라서 본 연구에서는 디지털 포렌식 관련 연구동향을 파악하고, 연구 활성화를 위한 객관적 데이터를 제공하기 위하여 메타분석을 진행하였다.

Objectives: The purpose of the research is understand the priorities of national competency standards vocational key competence factors in nurse who is work in Seoul and Incheon. Methods: The design of this study is descriptive investigation research, and the subjects were 144 nurse. we establish the vocational key competency defined in national competency standards as analytic hierarchy analysis model. The vocational key competency has 10 categories and 34 sub-categories. And based on the survey in nurse, the weight representing relative importance of each factor were calculated by using analytic hierarchy process method. Results: The analytic hierarchy process analysis on 10 categories showed that professional ethics(0.149) was higher than any other categories while that of numeracy(0.040) was at the bottom. And the analysis on sub-categories revealed that the most important factors in each categories included the Ethical community(Professional ethics), Conflict management skills(Interpersonal skills), Problem solving capability(Problem-solving skills), Listening skills(Communication skills), Applicable technical skills(Technical skills), Ability to understand business(Ability to understand organizational structures), Information processing capabilities(Information capacity), Self-management skills(Self-development capability), Ability to manage time(Resource management capabilities), Basic math skills(Numeracy). Conclusions: The results in this study can be used as basic data for the development of liberal arts curriculum for Nursing.

Borescopes facilitate the inspection of areas inside machines and systems that are not directly accessible for visual inspection. They offer real-time, up-close access to confined and hard-to-access spaces without having to dismantle or destructure the object under inspection. Borescopes are ideal instruments for routine maintenance, quality inspection and monitoring of systems and structures. The main application being fault or defect detection, it is useful to have measuring capability to quantify object dimensions in a target area. High-end borescopes use multi-optic solutions to provide measurement information of viewed objects. Multi-optic solutions can provide accurate measurements at the expense of structural complexity and cost increase. Measuring functionality is often unavailable in low-end, single camera borescopes. In this paper, a single camera measurement solution that enables the size estimation of viewed objects is proposed. The proposed solution computes and overlays a scaled grid of known spacing value over the screen view, enabling the human inspector to estimate the size of the objects in view. The proposed method provides a simple means of measurement that is applicable to low-end borescopes with no built-in measurement capability.

미래전의 양상은 첨단과학기술의 발전에 따라 다양한 유·무인 전투체계들이 전투를 수행하는 것으로 변화하고 있다. 미래의 무기체계들은 대량의 정보를 생성하고 송·수신하게 되며, 이에 따라 현재의 전술정보통신체계는 미래의 기반 통신체계로 운용하기에 제한된다. 또한 군단급 이상의 대규모 제대의 정보유통량을 분석하기 위해서는 전장에서 발생할 수 있는 다양한 상황들을 고려하여야 한다. 이에 본 논문에서는 Army TIGER 군단의 정보유통량을 분석하기 위해 지상망 단독 운용, 통합망 운용, 부하 분산, 장애 극복 시나리오 등 네 가지 시나리오를 기반으로 한 M&S 결과를 분석한다. 또한 지상·공중·우주망이 통합된 다계층 통합 전술통신망의 운용을 통해 네트워크의 신뢰성과 안정성을 향상할 수 있음을 제시한다.

As the DT of micro businesses emerges as an important task, the government is also promoting support projects such as policy establishment and micro business education. This study aims to develop a new index (checklist) that can objectively measure the level of digital literacy required for DT in the tertiary industry, which accounts for the largest share of micro business owners. In this study, indicators were derived through review of existing studies and FGI, and the validity and reliability of Likert 5 were measured for decision makers in the tertiary industry. In the field of digital literacy for micro business owners, a total of 22 indicators were developed, largely composed of basic technology environment competency, information utilization competency, information dissemination and production capability, and mind recognition capability. This study has academic significance in that it can contribute to accurately understanding the digital capabilities of micro business owners by developing a digital literacy index for micro business owners, a specific group lacking in research.
