The purpose of this study was try to check the change of a subjective evaluation about the life function fitness and health-related quality of life by executing the home support exercise program three times a week for total 16 weeks with elderly women that are order than 70 years old. The experiment group(total : 17 people, mean age : 79.4) and the control group(total : 17 people, mean age : 80.7) live Yeonje-gu in Busan city, and they don't have any physical injury and any inconvenience to move. and they are all composed of elderly women who agree to participate in this study. We carried out an analysis of covariance with SAS 9.2 statistics package. These are the results from it. First, the experiment group showed statistically significant increase(p<.001) in lifting dumbbells, repeatedly standing up and sitting down, 2.24m shuttle running, walking at the same place for 2 minutes. Second, there was no particular effect with the experiment group in flexibility(catching hands with their backs leaned against each other). This result point out that there is a need of supplementation like adding exercise item which can improve flexibility to home support exercise program. Third, there was no particular difference between the experiment group and the control group in 8 sub-factors with the subjective evaluation about health-related quality of life through SF-36. However, there the bodily pain and vitality sub-factors of experiment group was better than that of the control group with p<.10 level, so we considered this result showed us the positive effect slightly.

In an effort to resolve the burden of patients hiring patient sitters, this study sought to review the Ministry-of-Health-and-Welfare-initiated pilot program of running hospitals without patient-sitter to identify its background, operation method, performance results, and limitations. Based on the review, the study derived the necessity of introducing a hospital system without patient-sitter as well as its operation and systemization methods. The ministry-initiated pilot programs were conducted twice: in 2007, and in 2010. A review of the 2007 pilot program revealed that the patients and families' satisfaction score with nursing services was 9.1 points (on a 10-point scale), their intention to reuse the service was 97.8%, and their intention to recommend the service was 98.0%, all high scores. Appropriate nursing manpower, derived from the 2007 pilot project, indicated 2.3 patients per nurse and 4.0 patients per nurse aid. The 2010 pilot project results indicated that the patients and families' satisfaction was high at 8.0-9.1 points (on a 10-point scale), and that the intention to reuse and recommend the service was also high. Compared with the 2007 pilot project, however, the types of medical institutions and the nurse to patient ratios were diverse, offering limitations. In conclusion, to systemize hospitals without patient-sitter, it is necessary to develop policies designed to establish criteria for the appropriate nurse to patient ratio and skill-mix, to standardize the work, to prepare finances for securing nursing staff, to evaluate the nursing demands, and to monitor the quality management.

This research was focused on the distribution of Uranium-238 concentration in the Han River. Also, six water treatment plants in Seoul have been investigated to find out the behaviour and the removal capability of uranium. The uranium concentrations were ranged $0.02{\sim}0.54{\mu}g/L$ in the Han River. The relationship between conductivity and total dissolved solids shows that uranium concentration is positively related with conductivity and total dissolved solids. In addition, it has been founded that there was no relevance between uranium concentration and geological structure, because most of the sampling area are Banded Gneiss. The average uranium concentration in six water treatment plants was determined to $0.134\;{\mu}g/L$ in raw water, $0.050\;{\mu}g/L$ in coagulated water, $0.029\;{\mu}g/L$ in settled water, $0.020\;{\mu}g/L$ in filtered water, $0.019\;{\mu}g/L$ in finished water. After filtration in the treatment process, uranium concentration level was maintained lower than $0.029\;{\mu}g/L$. The average uranium removal efficiency compared to the raw water was 63% after coagulation, 15% after sedimentation, 8% after filtration and disinfection. The analysis shows that 78% of uranium in the raw water was removed during coagulation and sedimentation processes. However, 8% of that was removed through filtration and chlorination processes.

In the recent years, coaching leadership has been in the spotlight as being an essential human resources management strategy for improving organizational effectiveness in addition to strengthening the capacity of organizational members. Therefore, this study empirical analyses the effect of sales coaching on motivation and organizational effectiveness and the moderating effect of achievement needs. As a result, First, sales manager coaching appeared to have positive effect on the motivation and organizational effectiveness (job satisfaction, organizational commitment, job performance). Second, motivation appeared to have positive effect on organizational effectiveness. Third, achievement need appeared to have moderating effect in the relationship between sales manager coaching and organizational commitment. According to the study results, sales managers' coaching has positive effects on improving salespeople's performance as well as their levels of motivation, job satisfaction, and organizational commitment. In addition, this study proves that depending on the level of salespeople's need for achievement, the purpose and approach of coaching styles must be different to maximize the positive effects. This empirical study contributes to the theoretical as well as practical improvements of leadership coaching by verifying the conditional attributes for implementing effective sales managers' coaching for improving organizational effectiveness.

The purpose of this study is to develop a nursing activity cost calculation program based on Lee's doctoral dissertation using TD-ABC. The developed program has been supplemented with data storage, print out, and graph conversion functions to expand the application possibility. The development of the program consisted of three steps: program requirements analysis, program design and development, and program validation. This program was designed not only to do the cost calculation, but also to compare the cost-effectiveness and cost consumption trends. Consequently, this program is meaningful in that the nursing manager can obtain the cost information necessary for nursing unit management and extend the utilization so that the cost management strategy can be established based on the cost information. Therefore, we propose that the cost-management capacity of clinical nurses should be strengthened and the nursing performance measurement research should be expanded by applying it to various actual clinical nursing management settings. It is suggested that this program should be used as a training medium to strengthen nurse cost management capacity by combining nursing management curriculum at undergraduate level.

This paper presents the use of an Artificial Neural Network (ANN) as a viable means of forecasting Inundation Damage Area (IDA) in many watersheds. In order to develop the forecasting model with various environmental factors, we selected 108 watershed areas in South Korea and collected 49 damage data sets from 1990 to 2000, of which each set is composed of 27 parameters including the IDA, rainfall amount, and land use. After successful training processes of the ANN, a good agreement (R=0.92) is obtained (under present conditions) between the measured values of the IDA and those predicted by the developed ANN using the remaining 26 data sets as input parameters. The results indicate that the inundation damage is affected by not only meteorological information such as the rainfall amount, but also various environmental characteristics of the watersheds. So, the ANN proves its present ability to predict the IDA caused by an event of complex factors in a specific watershed area using accumulated temporal-spatial information, and it also shows a potential capability to handle complex non-linear dynamic phenomena of environmental changes. In this light, the ANN can be further harnessed to estimate the importance of certain input parameters to an output (e.g., the IDA in this study), quantify the significance of parameters involved in pre-existing models, and contribute to the presumption, selection, and calibration of input parameters of conventional models.

This paper presents a semantic vector space retrieval model incorporating a word sense disambiguation algorithm in an attempt to improve retrieval effectiveness. Nine Korean homonyms are selected for the sense disambiguation and retrieval experiments. The total of approximately 120,000 news articles comprise the raw test collection and 18 queries including homonyms as query words are used for the retrieval experiments. A Naive Bayes classifier and EM algorithm representing supervised and unsupervised learning algorithms respectively are used for the disambiguation process. The Naive Bayes classifier achieved $92\%$ disambiguation accuracy. while the clustering performance of the EM algorithm is $67\%$ on the average. The retrieval effectiveness of the semantic vector space model incorporating the Naive Bayes classifier showed $39.6\%$ precision achieving about $7.4\%$ improvement. However, the retrieval effectiveness of the EM algorithm-based semantic retrieval is $3\%$ lower than the baseline retrieval without disambiguation. It is worth noting that the performances of disambiguation and retrieval depend on the distribution patterns of homonyms to be disambiguated as well as the characteristics of queries.

The aim of this study is to evaluate the governance system involved in the policy of upgrading the Seongseo industrial complex in Daegu city. The governance system was evaluated by four indicators; social legitimacy, reliability, expertness, and transparency. The major findings of this study are summarized as follows. It is expected that the Seongseo industrial complex upgrading policy would accelerate to upgrade the industry structure and competitiveness of the cluster. However, the firms of the cluster have a Question of reliability to the actors of initiating the policy. In this context, to raise the trust level the policy needs to turn towards making the communication channel among the stake-holders of the cluster more democratically and horizontally. It is also problematic to reveal the low degree of expertness of the policy's decision makers, the fragmented system of policy operation and a lack of information. Consequently, the policy is required to improve the transparency on the policy-making process, and to activate the participation of professional groups and civil society.

We investigated the whether endurance exercise and MitoQ intake mediated neuroprotection are associated with mitochondrial function in 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine(MPTP) -induced mice model of Parkinson's disease. C57BL/6 male mice were randomly assigned to five groups: Normal Conrol(NC, n=10), MPTP Control(MC, n=10), MPTP +MitoQ(MQ, n=10), MPTP + Exercise(ME, n=10) and MPTP + MitoQ + Exercise(MQE, n=10). Exercise intervention groups performed the treadmill exercise for 5days/week for 5 weeks with gradual increase of intensity. MitoQ intake groups consumed the MitoQ at a concentration of 250μmol by dissolving with water during experiment period. Our data demonstrated that ME and MQE group restored MPTP-induced motor dysfunction. In addition, treatment groups(MQ, ME and MQE) increased tyrosine hydroxylase levels, and suppressed the accumulation of α-synuclein levels. Futhermore, treatment groups modulated the mitochondrial function such as upregulated mitochondrial biogenesis, increased antioxidant enzyme, enhanced a anti-apoptotic protein(e.g., BCL2), and reduced a pro-apoptotic protein(e.g., BAX). Taken together, these results suggested that endurance exercise and MitoQ intake-mediated increase in mitochondrial function contributes to improvement of aggravated dopaminergic neuronal, resulting in attenuation of motor function of Parkinson's disease.

According to the secondary data, private brand(PB)'s share of retail sales is 25-30% in the USA, but about 45 in Korea. In Korea PB's average price is 23.3% less than manufacturer brand. It is very interest that PB's price advantage doesn't have a good effect on it's share of retail sales. This research's objective is to study why Korean consumers don't purchase private brand cheaper than manufacturer brand. A theoretical reasoning depends on information cue theory and means-ends model of perceived value. A unit of analysis is consumers who purchase private brand at E-mart in Pusan city, one of largest discount store in Korea. Hypothesis tested by Lisrel's structural equation model and interesting results as follows: First, favorable brand image among extrinsic cues is most positively correlated with perceived quality/sacrifice and intrinsic cues is also statistically significant. This fact imply that intrinsic cues; package, logo, country of origin are very important in the adoption of private brand in Korea. Second, compared with manufacturer's brand, PB's perceived price is positively correlated with perceived quality/sacrifice. This fact imply a assimilation effect between manufacturer's brand and private brand. Finally, a correlation between perceived sacrifice and PB proneness is satistically insignificant, but perceived quality has a significant effect on its proneness. this fact imply that innovators(about 4% of potential consumer) are risk-taker.
