  • 본 연구는 맞춤형 착석장치를 통한 자세지지가 뇌성마비 아동의 상지 마우스 사용 능력에 미치는 영향을 알아보고자 실시하였다. 단일대상 연구방법의 하나인 ABAB 설계를 실시하였고, 경직성 사지마비로 진단받은 13세 뇌성마비 남아가 참여하였다. 대상자의 중재 전 휠체어 앉기 자세와 자세지지를 통한 중재 자세에서 마우스 클릭을 위한 반응시간과 정확도를 비교하였다. 중재 자세는 현행 임상지침과 상지 운동을 촉진하는 것으로 밝혀진 연구결과를 참고하였고, 대상자의 전형적인 휠체어 앉기 자세에서 도수 평가 후 맞춤형 착석장치를 통해 교정하였다. 연구 결과는 기초선 자세보다 중재 자세에서 마우스 클릭을 위한 반응시간이 감소한 것으로 나타났다. 마우스클릭의 정확도는 모든 단계에서 높게 나타나 분석을 실시하지 않았다. 이는 맞춤형 착석장치를 통한 기능적인 앉기 자세가 뇌성마비 아동의 상지 마우스 사용 능력에 긍정적인 영향을 미친다는 경험적 증거를 제공한다. 향후에는 다른 장애 유형과 더 많은 대상자를 상대로 맞춤형 착석장치가 사용자의 컴퓨터 접근성 향상 등 상지 기능에 효과적이라는 결과를 일반화할 수 있는 연구가 필요하다.

  • Most high efficiency silicon solar cells use a passivated selective emitter. It have been an important research subject for crystalline silicon solar cells for decades. It is being used in production for high efficiency solar cells. Most of the selective emitter process require expensive extra masking, etching steps, and a double diffusion process making selective emitters not cost effective. In this paper, we study method for single diffusion step selective emitter process as an alternative to not cost effective double diffusion process. Cost effective selective emitter that the efficiency should be increased significantly (mare than 0.2%) and that the process should simple, robust and cheap.

  • The purpose of this single subject care study was to evaluate the effectiveness of a functional electrical stimulation(FES) treatment program designed to prevent glenohumeral pint stretching and subsequent subluxation and shoulder pain in hemiplegic patients. The subject was a 43-year-old male who had left side hemiparesis with shoulder pain and subluxation on affected side. He received conventional physical therapy and additional FES therapy where two flaccid shoulder muscles, supraspinatus and posterior deltoid. were induced to contract repetitively up to 20 minutes for 2 weeks. As a result. the patient showed improvements in hemiplegic arm function, reduction in subluxation(as indicated by Jig test) and range of motion(SLROM). But it was difficult to generalize. We concluded that the FES program was effective in reducing the severity of shoulder subluxation and pain. Further study must be evaluated its statistical significance.

  • Purpose - Studies of mechanism as a competitive strategy, a relatively new field in the study of strategic management research, has recently drawn the attention of the business management scholars. The literature has so far proposed the subjective-based view, environment-based view, and the resource-based view in its analyses of firm management. Hence, it is highly likely for the firm management to be reasonably thought of as a combination of and interaction among the three key elements of subject, environment, and resources this is the mechanism-based view (MBV). It is reasonable to consider firm management to be the combination of and interaction among the three key elements of subject, environment, and resources. The overall dynamic process that integrates these three elements and creates functional harmony is identified as the mechanism, the principle of firm management. Much of the extant literatures on MBV has mainly focused on case studies, a qualitative approach prone to subjectivity of the researcher, although the intuition from the study may lead to meaningful insights into a firm-specific mechanism. This study's focus is also on case analysis, but it still attempts a quantitative approach in order to reach a scientific and systematic understanding of the MBV. Research design, data, and methodology - I used both a qualitative and quantitative approach to a single model, given the complexity of the innovation processes. I conducted in-depth interviews with POSCO employees-20 from general management, two from human resources, eight from information technology, five from finance and accounting, and five from production and logistics management. Once the innovative events were selected, the interview results were double-checked by the interviewees themselves to ensure the accuracy of the answers recorded. Based on the interview, I then conducted statistical validation using the survey results as well. Results - This study analyzes the building process of innovation and the effect of the mechanism pattern on innovation by examining the case of POSCO, which has survived over the past 21 years. I apply a new analytical tool to study mechanism innovation types, perform a new classification, and describe the interrelationships among the mechanism factors. This process allows me to see how the "Subject"factor interacts with the other factors. I found that, in the innovation process of the adoption stage, Subject had a mediating effect but that the mediating effect of resource and performance was smaller than the effect of Subject on performance alone. During the implementation stage, the mediating effect of Subject increased. Conclusion - Therefore, I have confirmed that the subject utilizes resources reasonably and efficiently. I have also advanced mechanism studies: whereas the field's research methods have been largely confined to single case studies, I have used both qualitative and quantitative methods to examine the relationships among mechanisms.

  • The purpose of this study is (1) to design and test a database which can be automatically classified, and (2) to generate automatic classification number by processing the keywords in titles using the code combination method of Colon Classification(CC) as well as an automatic recognition of subjects in order to develop an automatic classification system (Auto BC System) based on CC which can be applied to any research library. To conduct this study, 1,510 words in the fields of agricultrue and medicine were selected, analized in terms of [P], [M], [E], [S], [T] employed in CC, and included in a database for classification. For the above-mentioned subject fields, the principle of an automatic classification was specified in order to generate automatic classification codes as well as to perform an automatic subject recognition of the titles included. Whenever necessary, editing, deleting, appending and reindexing of a database can be made in this automatic classification system. Appendix 1 shows the result of the automatic classification of books in the fields of agriculture and medicine. The results of the study are summarized below. 1. The classification number for the title of a book can be automatically generated by using the facet principles of Colon Classification. 2. The automatic subject recognition of a book is achieved by designing a database making use of a globe-principle, and by specifying the subject field for each word. 3. The automatic subject-recognition of input data is achieved by measuring the number of searched words by each subject field. 4. The combination of classification numbers is achieved by flowcharting of classification formular of each subject field. 5. The efficient control of classification numbers is achieved by designing control codes on the database for classification. 6. The automatic classification by means of Auto BC has been proved to be successful in the research library concentrating on a Single field. The general library may have some problem in employing this system. The automatic classification through Auto BC has the following advantages: 1. Speed of the classification process can be improve. 2. The revision or updating of classification schemes can be facilitated. 3. Multiple concepts can be expressed in a single classification code. 4. The consistency of classification can be achieved with the classification formular rather than the classifier's subjective judgement. 5. A user's retrieving process can be made after combining the classification numbers through keywords relating to the material to be searched. 6. The materials can be classified by a librarian without subject backgrounds. 7. The large body of materials can be quickly classified by means of a machine processing. 8. This automatic classification is expected to make a good contribution to design of the total system for library operations. 9. The information flow among libraries can be promoted owing to the use of the same program for the automatic classification.

  • In this study we developed monosyllable lists for articulation test for Korean. We sampled 103,581 colloquial monosyllables, applied them to five selection rules that based on Korean linguistic characteristics, and finally constructed five different lists with fifty monosyllables. The validity test using the monaural impairment factors such as S/N ratio and cut-off frequency showed that articulation scores were chanted systematically according to the level of impairment factors. In addition, we investigated the effect of azimuth of a single competing sound upon articulation scores. The syllables were always reproduced by the loudspeaker in front of the subject, while Hoth noise were reproduced by the loudspeaker with varying azimuth around subject. The result indicated that the articulation depended on the azimuth of competing sound sources. Finally, no significant differences among lists were found in all experimental conditions.
