인터넷의 폭발적인 확산은 다양한 서비스를 지원하는 웹사이트를 활성화시켰고 구매나 콘텐츠의 이용과 같은 다양한 인터넷 기반의 비즈니스 활동이 일어나고 있다. 또한 사용자들에 대한 경쟁적인 서비스는 웹사이트 운영의 차별화 된 전략을 필요로 하게 만들었고, 개인화 된 서비스의 필요성을 대두시켰다. 개인화를 지원하는 서비스는 주로 고객의 개별적인 특성이나 선호도를 기반으로 정량적인 자료를 통해 이루어지고 있다. 본 연구는 인터넷 감성 커뮤니티에 로그인하는 사용자의 사용자 정보를 이용하여 생체리듬을 파악하고, 사용자의 생체리듬에 따라 로그인한 사용자의 생체리듬에 가장 적합한 사용자 인터페이스를 제공하는 인터넷 감성 커뮤니티 서비스 방법 및 시스템의 설계에 초점을 두고 있다. 제안한 시스템을 한 사용자 감성 기반의 개인화 된 서비스의 제공은 고객의 충성도의 향상을 통해 웹사이트 가치를 높일 수 있을 것이다.

본 논문에서는 대용량 음성인식 시스템의 인식시간을 감축하기 위하여 후보단어를 선정하는 효과적인 방법을 제안하고 이 방법의 성능을 향상시키기 위하여 spectral smoothing과 temporal smoothing을 사용하는 것에 관하여 연구하였다. 제안된 방법은 사전내의 각 단어에 대하여 음성인식 단위의 음성 spectrum관찰확률과 길이정보를 이용하여 대강의 관찰확률을 계산하여 후보단어를 선정한다. 제안된 방법을 음소단위의 HMM을 이용하는 1160단어 인식 시스템에 적용한 결과, 전체 계산량의 74% 가량을 감축할 수 있었으며 이때 인식율의 감소는 매우 작았다. 또한 제안된 대감의 likelihood점수 계산방법은 Viterbi방법에 의하여 계산되는 likelihood 점수를 잘 추정함을 알 수 있었다.

Purpose: This study was aimed to identify the factors that related the dietary behavior in coronary artery disease patients and to made the data for nursing which is thought to improve the dietary behavior. Method: The study population was the coronary artery disease patients who were treated at outpatient base. The study method was the dietary behavior, diet self-efficacy, perceived-healthy behavior, social support measurement & characteristics. All of the above tool was validated for its composition propriety and confidence. The statistical analysis was done by SPSS PC 11.0 program. and frequency, percentage, mean, standard deviation, Pearson's correlation was used for analysis. Results: The score of dietary behavior in the coronary artery disease patients was 4.57 point. The score of perceived-benefits was the highest among the association factor(point) and the score of perceived-barriers(m=2.78), diet self-efficacy(m=5.12), social support(m=4.86 point), exercise and chest pain. Conclusion: The development of the program for the efficient dietary education that prevents the progression of the coronary artery disease is needed.

This paper is about applying efficient data mining method which improves the score calculation and proper building performance of credit ranking score system. The main idea of this data mining technique is accomplishing such objectives by applying Correlation based Feature Selection which could also be used to verify the properness of existing rank scores quickly. This study selected 2047 manufacturing companies on KOSPI market during the period of 2009 to 2013, which have their own credit rank scores given by NICE information service agency. Regarding the relevant financial variables, total 80 variables were collected from KIS-Value and DART (Data Analysis, Retrieval and Transfer System). If correlation based feature selection could select more important variables, then required information and cost would be reduced significantly. Through analysis, this study show that the proposed correlation based feature selection method improves selection and classification process of credit rank system so that the accuracy and credibility would be increased while the cost for building system would be decreased.

Purpose: The aim of this study was to evaluate the efficiency of nursing units in a hospital using DEA. Methods: Data were collected using the medical information system of a general hospital in a city. Input variables were number of nurses, number of nurse-aides, number of beds, and overhead costs. Output variables included number of admitted patients, rate of bed utilization, satisfaction of discharged patients, and prevention rate of safety accidents and sores. EMS Window version 3.1 was used to measure the efficiency score and descriptive statistics were applied to analyze the general characteristics of variables. Results: The average efficiency score of 18 general nursing units was approximately .99. Nine nursing units had a 1.00 efficiency score. Conclusion: Our findings reveal that nursing units operated very efficiently. To increase efficiency of inefficient nursing units, we recommend results of the DEA slack analysis as a benchmark of the most efficient nursing unit.

The Chinese outward foreign direct investment (OFDI) involves various bilateral trade agreements and regional agreements signed between China and other countries. This study examines the impact of Chinese OFDI in ASEAN-5 countries through ASEAN-China Free Trade Agreement (ACFTA) namely Indonesia, Malaysia, Philippines, Singapore, and Thailand from 2000 to 2016. This study attempts to address three research objectives. The first is to examine the motives for China's investment in ASEAN-5. The second is to explore the different impacts of China's investment across countries. The third is to investigate whether the OFDI conducted by state-owned enterprises (SOEs) will produce different impacts on the firm's efficiency score. Using the DEA approach, this study finds evidence that the overall Chinese OFDI is relatively efficient. We find that the estimated efficiency score of this OFDI has improved in pre- and post ACFTA where a higher overall efficiency score was reported when comparing pre- and post ACFTA signing for both SOEs and NSOEs. Finally, China's parent firms' efficiencies showed higher scores among NSOEs compared to SOEs after the signing of ACFTA for all ASEAN countries except Malaysia. We highlight that the country's institutional infrastructure, earlier investment presence, and diplomatic ties help in shaping an effective trade agreement.

Purpose: The purpose of this study aims to provide a fundamental basis for more efficient human resource management of hospitals through career development and through lowering the rate of turnover of nurses. Method: The target group was 370 nurses who are currently employed at four general hospitals. Three hundred and twenty-nine documents were collected, and the statistical results were generated by the SAS program. Result: The average mean score of organizational commitment, career commitment and turnover intention were: 3.13 points for affective commitment, 3.09 points for continuance commitment and 2.92 points for normative commitment, out of a five point scale. The average mean score of career commitment and turnover intention was 2.89 and 3.28 points. The most influential variable in turnover intention was affective commitment out of organizational commitment. Conclusions: This study verified that organizational commitment and career commitment are key variables that could decrease turnover intentions.

Deterioration of the educational facilities built before 1985 is a serious situation. The purpose of this study is to present the efficient remodeling method of old educational facilities. This paper, part II, presents the systemic and synthetic judgment method of deterioration grade of structural components. Deterioration grade of the whole structural components are judged by synthetic evaluation score which is the total of the score of ten evaluation items. And we added the importance coefficient of the viewpoint of four performance to each evaluation item.

In this thesis. we estimated the good reliability coefficient ${\beta}$$\sub$k/ that is unbiased, consistent and more efficient than Cronbach's ${\alpha}$$\sub$k/ in splitting of a test into several formats of subtests and several properties of ${\beta}$$\sub$k/ are also represented. The tables of coefficients of skewness and kurtosis are represented to test the significance of departures from normality. We got the cumulative normal plots of z'from the distribution which is departed from normality using the Bock's approximation procedure and we finally enumerated the transformed standardized scores z'and a new raw score X' which enable us to proceed further evaluation procedures depending on our assessment policy.

This paper presents two adaptive fingerprint matching methods. First, we experiment an adaptive threshold selection of 1:N matching system in order to raise the reliability of the matching score. Second, we propose a adaptive threshold selection using fitting algorithm for high speed matching. The experiment was conducted on the NITZEN database, which has 5247 samples. Consequently, this paper shows that our suggested method can perform 1.88 times faster matching speed than the bidirectional matching speed. And, we prove that FRR of our suggested method decreases 1.43 % than that of the unidirectional matching.
