Purpose: The purpose of this study was to study Complementary and Alternative Medicine (CAM) used among degenerative arthritis patients in Korea. Method: This study used a descriptive survey method. Study subjects of the study were 278 degenerative arthritics selected from hospitals located in Kyungpook province and Daegu city. Data were collected between February 15, 2007 and March 31, 2007. Results: 62.6% of degenerative arthritics had used CAM. Manipulative Methods has shown to be one of the most effective methods on CAM. The utilization of CAM may be interpreted mainly due to the desperate need find therapeutics of their disease by all possible means (57.5%). Major factors that affect the decision of the patient include family, relatives, friends(42%), and the other patients who were in the similar circumstance (32.8%). Effectiveness of CAM has shown the following result "for complete cure of symptoms(77.0%), for health promotion (42.0%) and for psychological stabilization (29.9%)". 43.7% of the patients answered that they stopped of using CAM because of non-effectiveness. Conclusion: This study found that CAM among degenerative arthritic patients was a popular alternative method. Therefore, some nursing-oriented intervention method is needed together with a systematic guidelines of CAM usage is required.

Purpose: Home health nurses could affect patients' choice of alternative therapy. This study was carried out to investigate home health nurses' attitudes and cognition toward alternative therapy. Method: The subjects were 92 nurses who preparing the home health nurses at 2 university in Seoul and Suwon. Using the questionnaire. we measured the subjects' attitudes and cognition toward alternative therapy. Result: The mean score of attitudes about application was 3.14. and the score of attitudes about therapeutic effect was 2.57. The score of attitudes about therapeutic effect were significantly positive correlation to the score of cognition about alternative therapy. The attitudes about therapeutic effect were different significantly according to number of working years. But they commonly wanted to apply the soojichim. aroma-therapy. massage. danjon breathing. music therapy. plant therapy. and foot reflexology to their home health care subjects. Conclusion: Alternative therapies became a popular source of health care in Korea. This study showed pre-home health nurses had positive attitudes toward alternative therapies and they had wide variations of knowledge in how to use each therapy. But they acknowledge the value of alternative therapies as useful nursing interventions. so we all nurses should pay attention to develope the nursing intervention using alternative therapy.

The purpose of this study is to define the altenative assessment and to suggest the method of scoring system. Alternative assessment includes any type of assessment in which student create reponses to a question rather than choosing a responses form given list( as for multiple choice, true/false, or matching). Alternative assessment can includes short answer questions, essay, performances, oral presentation, demonstrations, exhibitions, portfolios, and etc. To evaluate the each type of assessment, we can apply the method of holistic scoring and analytic scoring system. Also we have to concern the type of scoring mechanism directly relate to what we want to assess, our purpose for assessment fitting into the educational enterprise. Before applying the alternative assessment in our classroom, we need to step back and reconsider all our design features and teachers' responsibility.

In case that any jobs in a Job Shop can be scheduled on more than one machine and may have flexible operation sequences, with considering such case it is very difficult and complex to make the optimal process plans and scheduling. But they should be considered for an integrated model to perform more effective process planning and scheduling in this job shop problem. In this paper, we propose GA-based scheduling method to integrate effectively the problem of alternative machines, alternative operation sequences and scheduling. The performance of proposed GA is evaluated through comparing integrated scheduling with not integrated scheduling in molding company with alternative machines and operation sequences. Also, we use benchmark problems to evaluate performance. The scheduling method in this research will apply usefully to real world scheduling problems.

Present study is undertaken to optimize the lubrication reliability and frictional loss of the dynamically-loaded journal bearing in hermetic reciprocating compressor with alternative refrigerant R600a application. Thermodynamic and dynamic analysis has been conducted to investigate cylinder pressure variations by substitution alternative refrigerant R600a for R12. The modeling of the dynamics of the compressor mechanism has been performed with lumped mass method. A mathematical model is developed for analyzing the dynamics of the journal bearing system with the mobility method. It takes into account the effects of the refrigerant species, aspect ratio, clearance ratio and surface roughness. A corresponding computer program is described which enables to obtain the minimum film thickness and frictional loss. Design optimization is graphically performed by parametric studies of the aspect ratio and clearance ratio.

This paper proposes a heuristic method for job shop scheduling with alternative machines. Our heuristic suggests four machine-selecting rules and two priority dispatching rules for modifying existent ones considering alternative machines, and then it extends existing nondelay/active job shop schedule generation. This heuristic provides good criteria(rules) in the selection of a proper machine among those performing a specific operation and for the dispatch of an operation to a selected machine and thus these rules permit the efficient job shop scheduling with alternative machines. The performances of our four machine-selecting rules in addition to the two priority dispatching rules, applied together with the existing 17 rules, are experimented and evaluated, respectively.

Purpose: This study proposed an improved method of teaching cardiopulmonary resuscitation (CPR). Methods: A teaching method for CPR using a song was evaluated. To validate the effect of this teaching method, we performed a comparative reference test against a traditional CPR lecture-oriented education method. A total of 202 study participants were enrolled in this project. Half were taught by the traditional CPR education method, and the other half were taught by the alternative educational method using a song. Results: The results for those educated by the traditional lecture-oriented method showed scores of 4.84 / 6.00 (Mean of knowledge) and 70.22 / 100 (Mean of practice ability for CPR). The results for those educated by the alternative method showed scores of 5.26 / 6.00 (Mean of knowledge) and 74.13 / 100 (Mean of practice ability for CPR). The alternative educational method utilizing a song improved the results on written and practical examinations. This improvement could be attributed to the effect of music on memory circuits in the brain. Conclusion: We believe that the results of this study will help to improve the success rates of CPR.

The purpose of this study was to validate alternative method by using non-carcinogenic, and less toxic solvents than NIOSH analytical method 5524 for measuring the airborne MWFs in workplaces. In laboratory tests, the ETM solvents(mixture of same volume for ethyl ether, toluene, and ethanol) were selected. The alternative method of analyzing MWFs, referred to as the ETM solvent extraction method, showed 0.04 mg/sample as LOD, and 0.15 mg/sample as LOQ. The analytical precision (pooled CV, coefficient of variation) of the ETM solvent extraction method for analyzing the straight, soluble, semisynthetic, and synthetic metalworking fluid was 1.5%, 2.0%, 2.6%, 1.6%, respectively, which was similar to the precision (2.6%) of NIOSH analytical method (NIOSH 0500) for total dust. The analytical accuracy by recovery test, spiked mass calculated as extractable mass, was almost 100%. As the result of storage stability test, metalworking fluid samples should be stored in refrigerated condition, and be analyzed in two weeks after sampling. The 95% confidence limit of the estimated total standard error for the ETM solvent extraction method for analyzing the straight, soluble, semisynthetic, and synthetic metalworking fluid was ${\pm}12.6%$, ${\pm}12.5%$, ${\pm}14.0%$, and ${\pm}13.6%$, respectively, which satisfied the OSHA sampling and analytical criteria.

Land suitability assessment(LSA) is a useful method to assess land characteristics according to its physical, locational, and environmental characteristics, and then to classify it into several categories based on its usability and the necessity for conservation. Therefore, the credibility of this assessment result depends on the rationality of assessment method such as computation of suitability values and the criteria of ranking the land grade. This study focused on identifying problems in current LSA method by critically reviewing it, and aimed to suggest a suitable method for the assessment of land suitability. As a alternative method in this study, linear transformation method was used for scoring factors instead of critical values and the weight for each assessment factor. and all values of those factors were added to produce comprehensive suitability values. Those values were ordered and categorizied with suitability level based on the ratio of square measure. After comparing existing LSA method to the suggested alternative method, it is concluded that the alternative method was more suitable to assess the characteristics of lands than existing LSA method. This method was also suitable to represent the characteristics of various assessment factors. Field survey using satellite image clearly revealed the suitability of the alternative method compared to an existing method of land assessment. Furthermore, the alternative method of grading the land suitability improves the problem of using standardiZiation method and gives more flexibility, which makes this method very rational.
