  • 기업은 조직내에서 공유되고 사용되는 지식을 경쟁우위와 직결된 지적자본으로 인식하고 있다. 이에 따라 많은 선행연구에서 지식근로자 사이에 공유되는 지식을 파악하고자 노력하였다. 선행 연구의 한 가지 접근법은 정보기술을 이용하여 자동화되고 효율적으로 명시적인 지식을 공유하는 기술적인 방법을 강조하는 접근법이며 다른 접근법은 지식근로자간 휴먼 네트워크를 이용하여 암묵적인 지식의 흐름을 파악하고자 하는 연구이다. 두 번째 접근법의 경우 지식공유를 위해 실행공동체의 역할이 강조되고 있으나 자발적인 참여가 아닌 경우 실행공동체를 파악하기 힘들다는 단점이 있다. 본 연구에서는 휴먼 네트워크를 사회연결망 관점에서 파악하여 지식의 전파를 분석하고 실행공동체에 참여할 수 있는 지식근로자를 찾아내는 방법을 제안하고자 한다. 이를 위해 두 가지 사회연결망 관련 지표를 이용하여 지식 근로자를 분류하는 프레임워크를 제시하고 실무적용 가능성을 확인한 결과를 제시하고자 한다.

  • Statement of problem: A tenderness of the dentin after tapering of teeth for dental prosthesis is a common phenomenon. In practice, the alternative desensitizer may be used for minor pain after tapering of teeth. Purpose: In this study, the desensitizers were used to investigate the affect decreasing of shear bond strength according to the use of various cement, such as resin, Glass Ionomer, and phosphate cement. Material and method: Three different desensitizers were used on this study Compositions of two dentin desensitizers were HEMA(hydroxyethylmethacrylate) and glutaraldehyde. The other one is oxalic acid. Three dentin desensitizers applied on 12 degrees taper teeth. Then, Ni-Cr crowns were bonded with Resin cement, Zinc Phosphate (ZPC) cement and Glass Ionomer (GIC) cement. 120 human premolar teeth were used for specimens. The specimens were divided into four group as the reference and the empirical each with thirty specimens, then further divided into 12 group according to type of desensitizers and cement types. The shear bond strength were measured by Instron multi task instrument. Results: According to the result, the measured shear bond strength in order from the weakest to the strongest in general was ZPC, Resin, and GIC. And it is found that the application of desensitizers on dentin surface does not affect the shear bond strength. Conclusion: Dentin desensitizers that alleviate or prevent a dentin tenderness, usually contains HEMA and glutaraldehyde compounds. Such desensitizers are widely used in clinical studies. By applying the dentin desensitizer on the exposed dentin surface, the dentin capillary are blocked and periodontal membrane and cementum can not be drawn in pulp cavity. Since HEMA and glutaraldehyde may cause harm to the pulp cavity, an alternative desensitizer was developed.

  • This article a little bit lack of elements for the basis of study of health care in the respect of taking a certain expert group as the sample. However researcher chose people who is in same situation with himself and tried to make clear how to do for their behavior of health care to know that how the experts groups are taking care of their health. For the study, the main aim of this article is studying the health care situation of experts group which is taking crucial role in the economy, society and cultural field. When it comes to the experts group's health care by eating habits and exercise related program is, first, it indicates that most people are eating for their health, lives and work through the analysis of responds; they eat food for their health and their health, lives or task.(Surely they family-centered structure. Third, 78% of 40s group responded that they enjoy finding good restaurants while 20s to 30s are enjoying fastfood and instant food instead of Korean traditional foods. fourth, health care by the exercise is done in one or half one hour and the dependant exercises like jogging or swimming which can be done whenever they have time are perferred to group exercise. It's desirable that one has to take care of himself with systematic and effective way. But it's very difficult and care for most people to take care of themselves, so they have to make the program and practice it systematically. The result from this study shows that practicing the health related program rationally, at the same time increasing leisure time and doing dependant or group exercise, taking a walk, and various kind of exercise considered spending money are more common than eating foods for health care. These are regarded as a desirable phenomenon in terms of the health care.

  • The purpose of this descriptive study was to identify problems and solving strategies on student evaluation of clinical nursing education. Subjects were 239 nurses in 18 hospitals from February to July, 1999. Content analysis using qualitative research method was used to analyze data taking into account the semi-structured questionnaire. The results of this study were as follows: Four categories about problems and solving strategies on the evaluation of clinical nursing education were identified: 'The environment of the clinical nursing education'; 'contents and items of evaluation tool'; 'criteria of evaluation tool'; and 'problems with evaluators in clinical settings'. The problems of the environment of the clinical nursing education were due to the lack of co-ordination between nursing schools and hospitals. In order to solve these problems, the following strategies were suggested: 'initiate a joint meeting between nursing schools and hospitals'; 'do not change the clinical settings frequently'; 'evaluate students after being familiar with them'; and 'evaluate them immediately after clinical practice was ended'. In the problems of contents and items of the evaluation tool, the contents of the tool were very abstract and general. The strategies for treating these problems were to evaluate student using the concrete evaluation items'; refrain from evaluation of nursing knowledge', develop the evaluation tools that are fit for a specific clinical setting'; develop the evaluation tools in line with students' knowledge level; and 'carry out evaluation using the proper contents of tool. The problems of criteria of the evaluation tools were the results of the lack of the clear criteria. The strategies for treating these problems were 'develop the criteria of the evaluation tool'; simplify the range of the cores or evaluate students using check-list'; to evaluate students in objective manner'. The problem of evaluators in clinical settings was due to the failure by evaluators who were not prepared for the task. The strategies were 'to educate and prepare the evaluators before evaluation'.

  • In modern systems design and development, one of the key issues is considered to be related with how to reflect faithfully the stakeholder requirements including customer requirements therein, thereby successfully implementing the system functions derived from the requirements. On the other hand, the issue of safety management is also becoming greatly important these days, particularly in the operational phase of the systems under development. An approach to safety management can be based on the use of the failure mode effect and analysis (FMEA), which has been a core method adopted in automotive industry to reduce the potential failure. The fact that a successful development of cars needs to consider both the complexity and failure throughout the whole life cycle calls for the necessity of applying the systems engineering (SE) process. To meet such a need, in this paper a method of FMEA is developed based on the SE concept. To do so, a process model is derived first in order to identify the required activities that must be satisfied in automotive design while reducing the possibility of failure. Specifically, the stakeholder requirements were analyzed first to derive a set of functions, which subsequentially leads to the task of identifying necessary HW/SW components. Then the derived functions were allocated to appropriate HW/SW components. During this design process, the traceability between the functions and HW/SW components were generated. The traceability can play a key role when FMEA is performed to predict the potential failure that can be described with the routes from the components through the linked functions. As a case study, the developed process model has been applied in a project carried out in practice. The results turned out to demonstrate the usefulness of the approach.

  • 본 연구는 간호학생이 첫 임상실습을 경험한 후 달라진 전문직관, 직무만족, 역할갈등의 변화를 파악하며 간호학생의 임상 실습교육 향상을 위한 기초자료를 제공하자고 시도되었다. 첫 임상실습 후 간호학생의 전무직관(t=-2.184, p=.031), 직무만족(t=-2.068, p>.001)은 상승하였다. 그러나 부정적 요소인 역할갈등(t=-3.729, p>.001) 역시 상승하였다. 즉, 간호학생은 첫 임상실습을 통해 예비간호전문인으로서 바른 전문직관을 세우고 자신의 업무에 대해 만족감을 느꼈다. 그러나 간호학생은 첫 임상실습을 통해 임상에서의 현실적인 간호사 역할을 경험한 후, 오히려 심각하게 자신의 미래 직업에 대한 고민을 하는 것을 알 수 있었다. 특히 역할갈등의 하부영역 중 개인 내 갈등(t=-3.729, p>.001), 역할모호성(t=-5.720, p>.001)에서 심각한 갈등을 느끼므로, 간호학생을 위한 업무기준과 직준표준안 마련에 대해 간호교육계 및 임상실무 현장 전반에 걸쳐 논의가 필요할 것으로 사료된다.

  • Objectives : The Dongui Bogam in My Hand', which is an output of computerizing Donguibogam (Principles and Practice of Eastern Medicine), is an interim outcome of the research project led by the Korea Institute of Oriental Medicine. This study examined the process in which Donguibogam, a record in Chinese and a classic of Oriental medicine, expanded into a modern content. Methods : This study will classify the modernization of Donguibogam into three 'contents' that form Donguibogam, 'container' that will hold the contents, and 'community' that is the consumer of Donguibogam. Towards the end, this study will sketch out the status of computerizing Chinese records in Korea, and point out the reality faced by computerization of ancient documents on Oriental medicine as well as the direction for the future. Results : 'The Dongui Bogam in My Hand' has been downloaded more than 10,000 times for 4 months since it releases in August 2014, and is used for at least 6,000 times on average every month. This achievement can be due to the two following reasons. First, the application contains high-quality contents such as the original text of Donguibogam as well as Korean and English translations. Second, it satisfied the needs of Donguibogam users with (1) the Browse function that well displays the table of contents, (2) the Search function that separates the title from the main text, and (3) the Personalization function designed to link and share relevant knowledge. Conclusions : Computerization of Chinese records was triggered by the request of the academia, but it was accelerated after being selected as a public laboring project to overcome the IMF crisis. However, computerization of ancient documents is not a simple task but a field of study to modernize classical knowledge. The success or failure of computerization of Chinese records is determined by whether high-quality modern 'contents' are secured, whether the 'container' design adequately implements the search, browse and link functions, and how well it fulfills the needs of the consumer 'community'.

  • Public libraries provide information to all persons and its users are the inhabitants of the community it serves. This may not be the reality in some cases as some category of persons may not be properly served by the public library. This study assesses the provision of information materials in alternative format, in terms of its availability, access and level of use by the visually impaired in public libraries in southwestern Nigeria. The study adopted survey research design. Four (4) public libraries in four states were purposively selected because they are the ones that provide alternative format for the use of a sizable number of the visually impaired. Complete enumeration was used to capture all the 166 registered users of the libraries through the use of observations checklist and interview schedule. Data from 69.2% of the 166 visually impaired persons that were interviewed, and the observations made were analyzed. The result reveals that alternative formats availability were inadequate and, e-resources were not available while access to formats and information desired by the users were limited. Braille is the most utilized format; audio materials and large prints were seldom used. The demand for alternative formats is high but it is not related to level of use of materials. Provision of information materials in alternative formats for the visually impaired in public libraries cannot support the needs of the visually impaired; it requires intervention from all stakeholders. The study recommends improved investment and funding for public libraries and services to persons with disabilities.
