Purpose: The purposes of this study were to develop a nursing assessment tool for senior center nurses, and to test its feasibility and content validity. Methods: The study utilized a psychometric test design. Preliminary items were developed based on geriatric health needs and Gordon's 11 domains of functioning health. Initially, the tool was evaluated for content validity and feasibility. Then, it was administered among 195 older adults in a senior center by a gerontological nurse practitioner. Data were analyzed to describe the nursing problems of the senior center older adults. Results: The final version of the nursing assessment tool consisted of 27 items. The internal consistency, measured with the Cronbach's ${\alpha}$, was .74. The result of the assessment showed that senior center older adults had high nursing needs in the area of management of chronic diseases (hypertension, diabetes, and lipids), dental care, community relations, safety, elder abuse, health behaviors (such as drinking), mental health (depression, suicide, and cognitive function), and health consultations. Conclusion: The new tool was feasible for use with senior center participants, and it was evaluated as having high content validity by senior center nurses.

Programming is very important subject in computer science and similar computer-related areas such as electronics engineering, etc. Programming is also important for information education for elementary, middle, and high school students since programming is one of the most basic subjects in computer science courses and other similar areas. In current information and knowledge society, raising programming ability is a key factor for everyone's competitiveness. With highly-competitive programming ability, one can enjoy his or her daily life abundantly. He or she also can get a highly-paid job, and make money using his or her programming ability. In this paper, a programming ability assessment tool is developed and introduced for the no-programming experienced. It is very difficult to test programming ability for the no-programming experienced with non-programming tools or activities. In this paper, a programming ability assessment tool is developed based on logical thinking ability. Especially the proposed tool consists of 15 questions for test one's logical thinking ability. The tool does not require any computer science or programming background. The proposed tool will be helpful as criteria for entrance examination or job screening examination for programming-related areas or subjects.

소프트웨어를 재사용하는 경우 부품의 품질은 새로 개발한 시스템의 품질에 매우 큰 영향을 미친다. 따라서 재사용 라이브러리를 구성할 때 품질에 대한 평가와 검증은 필수적이다. 여러번 다시 사용하는 재사용 소프트웨어는 일반적인 일회적 소프트웨어에 대한 품질 평가와는 다른 기준으로 평가할 필요가 있다. 사용자 인터페이스나 기능적인 측면보다는 확장성과 정확성 등이 더욱 중요한 품질 요소가 된다. 본 논문은 멀티미디어 재사용 부품 저장소 및 재사용 시스템(Reusable Software for Multimedia Objects)의 일부인 객체 부품화 및 품질 평가 기술 개발에 관한 것으로 C++및 IDL(Interface Definition Language)로 표현된 재사용 부품을 읽어 구문 형식, 구조, 객체 결합도, 객체 응집도, 객체 복잡도, 이해도 등의 관점에서 분석하고 품질 만족도를 출력하는 품질평가 도구를 다루었다. 또한 분산 환경에서 품질 검증 시스템을 사용할 수 있도록 CORBA기반에서 설계하였다.

The prediction for tool life is one of the most important factors for increasing reliability, stability, and productivity of manufacturing system. This paper deals with a tool life prediction method in view of reliability assessment for cutting tools. In this study, flank wear was focused among multi-factors deciding the tool wear state. First, tool life was predicted by correlation between flank wear and cutting time, based on the extended Taylor tool life equation of turning, including parameters of cutting speed, feed rate, and cutting depth. Second, each of cutting conditions of end-milling was equivalently converted to apply ball end-mill data to the extended Taylor equation. The web-based prediction program for tool life was developed as one of reliability assessment programs for machine tools.

The reference stations in a satellite-based augmentation system (SBAS) collect raw data from global navigation satellite system (GNSS) to generate correction and integrity information. The multipath signals degrade GNSS raw data quality and have adverse effects on the SBAS performance. The currently operating SBASs (WAAS and EGNOS, etc.) survey existing commercial equipment to perform multipath assessment around the antennas. For the multi-path assessment, signal power of GNSS and multipath at the MEDLL receiver of NovAtel were estimated and the results were replicated by a ratio of signal power estimated at NovAtel Multipath Assessment Tool (MAT). However, the same experiment environment used in existing systems cannot be configured in reference stations in Korean augmentation satellite system (KASS) due to the discontinued model of MAT and MEDLL receivers used in the existing systems. This paper proposes a test environment for multipath assessment around the antennas in KASS Multipath Assessment Tool (K-MAT) for multipath assessment. K-MAT estimates a multipath error contained in the code pseudorange using linear combination between the measurements and replicates the results through polar plot and histogram for multipath assessment using the estimated values.

This study tried to suggest the basic materials that can be efficiently applied in clinical cases by understanding problems through a content analysis of an adult nursing assessment tool and opinion agreement about nurse's practical usage presently used in the hospital. The study was carried out in 36 attached hospitals in nationwide universities from May to December, 1999, the two hundred and twenty five reports were for analysis. The contents of the collected nursing assessment tool were analyzed. It was found that the tool had been used with various names and content and there were instances of partial omission of a number of items, such as documentation and time records. Other results revealed that they mostly had a systematic classification of items, formation of details a form of a check list, and the effect of saving time. In spite of the adult nursing assessment tool, it was suggested that its style be subdivided according to the specialized of a department and that standardized style be amended and supplemented. The respondents also answered that there had to be education about continuous and sufficient health assessment skills on the physical examination record. The most frequently suggested items to be added were: past history, marital status, patient and caregiver's address and telephone number. It was found that a patient's education career, economic status, religion, hygienic practice, sexual life and hobby were the most frequently omitted items on record. The reason given wes because the items were associated with his/her privacy. These results highlight the importance of analyzing the content with an complete data collection, supplying basic content for a more accurate nursing record, computerization, sharing information and standardization of the form.

Purpose: The purpose of this study was to determine the significant factors for risk estimate of aspiration and to evaluate the efficiency of the dysphagia assessment tool. Methods: A consecutive series of 210 stroke patients with aspiration symptoms such as cough and dysphagia who had soft or regular diet without tube feeding were examined. The dysphagia assessment tool for aspiration was compared with videofluoroscopy using Classification and Regression Tree (CART) analysis. Results: In CART analysis, of 34 factors, the significant factors for estimating risk of aspiration were cough during swallowing, oral stasis, facial symmetry, salivary drooling, and cough after swallowing. The risk estimate error of the revised dysphagia assessment tool was 25.2%, equal to that of videofluoroscopy. Conclusion: The results indicate that the dysphagia assessment tool developed and examined in this study was potentially useful in the clinical field and the primary risk estimating factor was cough during swallowing. Oral stasis, facial symmetry, salivary drooling, cough after swallowing were other significant factors, and based on these results, the dysphagia assessment tool for aspiration was revised and complemented.
