This study investigate the influence of resilience on organizational commitment using social support as a mediating variable for kindergarten and childcare teathers. The subjects were 630 kindergarten and childcare teathers. The collected data were analyzed by Pearson's correlation as well as single and multiple regressions that used SPSS Win 19.0. The results were as follows: (1) The resilience was significantly associated with organizational commitment of kindergarten and childcare teachers. (2) The resilience was significantly associated with social support of kindergarten and childcare teachers. (3) The resilience was not significantly associated with organizational commitment of kindergarten and childcare teachers, controlled by social support. The results showed the social support was more important variable affecting organizational commitment of kindergarten and childcare teachers than the resilience. As a result, teachers have to be strengthened for support of social emotion that helps to control of their emotional condition and social evaluation that estimates their role positive under administration system.

An automatic titration was performed by a home-made automatic control system adopting a micro pH electrode as its sensing part in microdiffusion-based volatile basic nitrogen (VBN) analysis. The micro electrode was considered to be adequate for automatic VBN analysis because of its small sensor size, low immersion depth and unbreakable body. Six pork samples in different degree of freshness were analyzed both manually and automatically. The data from automatic titration were not significantly different from those taken by manual titration even at 15% significance level. The correlation coefficient was 1.000.

Smart home is one of the ubiquitous environment platforms with various complex sensor-and-control network. In this paper, a now learning methodology for learning user's behavior preference pattern is proposed in the sense of reductive user's cognitive load to access complex interfaces and providing personalized services. We propose a fuzzy inductive learning methodology based on life-long learning paradigm for knowledge discovery, which tries to construct efficient fuzzy partition for each input space and to extract fuzzy association rules from the numerical data pattern.

Recently, a cryptographic construct, called fuzzy vault, has been proposed for crypto-biometric systems, and some implementations for fingerprint have been reported to protect the stored fingerprint template by hiding the fingerprint features. In this paper, we implement the fuzzy fingerprint vault, combining fingerprint verification and fuzzy vault scheme to protect fingerprint templates. To implement the fuzzy fingerprint vault as a complete system, we have to consider several practical issues such as automatic fingerprint alignment, verification accuracy, execution time, error correcting code, etc. In addition, to protect the fuzzy fingerprint vault from the correlation attack, we propose an approach to insert chaffs in a structured way such that distinguishing the fingerprint minutiae and the chaff points obtained from two applications is computationally hard. Based on the experimental results, we confirm that the proposed approach provides higher security than inserting chaffs randomly without a significant degradation of the verification accuracy, and our implementation can be used for real applications.

The purpose of this study is to structure finance management education programme and to provide basic data orienting finance service system by means of analyzing the level of financial problem and its influential variables. The following is the result of this study: First, the level of financial problem perceived by housewife in urban areas is in the following order ; property which is perceived the least. Second, the level of financial problem perceived by housewife in urban areas is dependant on housewife age, husband education level, husband occupation, the degree of property, the degree of debts, tendency of fortune control, tendency of materialism, feeling of appropriate resource. It is especially noting that housewife in forties shows high level of financial of financial problem recognition than housewife in twenties does. This indicates needs for middle for middle-aged home management in which happens house moving to larger size, education of children, marriage of children, preparation for stabilization basis after children’s marriage, and shortage of surplus money. Third, variables which affect all sub-areas are family property sum, tendency of materialism, feeding of appropriate resources. The less family property sum, the stronger tendency of materialism, and the more perceive feeling of appropriate resources, the more perceive they financial problems.

This study was performed to provide basic data that predict the application of Saengmaegsan(SMS) as medicinal food. SMS has been used in oriental medicine for many years as a therapeutic agent for cerebral disease. We examined the effects of SMS on physiological function in isolated abdominal aorta and femoral artery from rabbit and measured the changes of regional cerebral hood flow(rCBF), which was continually monitored by laser-doppler flowmeter and pressure transducer in anesthetized adult Spargue-Dawley rats through the data acquisition system composed of MacLab and Macintosh computer. The contraction forces by injection of norephinephrine in isolated abdominal aorta and femoral artery were significantly decreased in each concentration of SMS treatment compared with control. rCBF was increased by SMS in a dose-dependent manner. These results suggest that SMS causes a diverse response of rCBF and arterial diameter. These mechanism in rCBF increase may be mediated by prostaglandis, cyclic GMP and adrenergic $\beta-receptor$. Also mechanism in artery contraction decrease is also mediated by prostaglandis and cyclic GMP. These results indicate that SMS can be nsed as a safe and clinically applicable as a supplementation of diet therapy for cerebral cardiovascular disease patients.

Baby boomers who have rebuilt the Korean economy over the last half a century are now transitioning into a silver generation who are over 65 years of age. New silver consumers are qualitatively and quantitatively different from the previous generation and are considered to be 'the single most consumption-leading generation.' The number of new silver consumers using department stores and traditional markets has increased. SPSS ver. 21.0 was used with the methods of frequency analysis, t-test, one-way analysis of variance (ANOVA), device master record test, and regression analysis. This research studies consumer satisfaction of new silver consumers on department stores and traditional markets among retailing. The improvement of the parking environment is the most urgent issue for traditional markets because the long-term assessments of parking areas indicate that it is necessary to provide improved convenience for consumers. Salesman satisfaction has improved and consumer satisfaction ranks salesman satisfaction high for traditional markets; however, price satisfaction is low and the distribution system should be improved to supply products at a lower price. Salesman and price satisfaction should be improved at depart stores. Traditional markets should also promote consumer satisfaction through consistent management to make consumers trust information in regards to quality control and production and distribution; in addition, department stores should increase consumer satisfaction by maintaining store systems such as product diversification and display, cleanness, and atmosphere.

In accordance with global energy conservation policies such as MEPS (Minimum Energy Performance Standard), electric motor industry is moving to super-high-efficiency machines and research to develop IE4 (International Energy Efficiency Class 4) motors has been launched. In this situation, SynRM (Synchronous Reluctance Motor) has been attracting attention in place of induction motor which hardly provides super premium efficiency. As a result, much research on SynRM is being performed at home and abroad. Also, some products have already been appearing in the market. Compared to induction motor, SynRM has better efficiency per unit area and wider operating range. Although the utilization of control system in synchronous motor results in higher prices, we still need to concentrate on developments of SynRM so as to comply with the new policies. This study demonstrated the electromagnetic design methods of super premium SynRM while maintaining the frame of existing IE3 induction motor. We documented the design procedures for generating high saliency which is the most essential and mechanical stress anlaysis is also treated. In conclusion, we proved the validity of our design by manufacturing and testing our 3 models.

Nowadays, to realize ubiquitous computing environment, many research activities have been going on within various kinds of research domains including automatic identification sensor network, home network, telematics and so on. Especially, RFID middleware that supports the aggregation of RFID tag data, control and management, and the integration with legacy systems has recently gained a lot of attention. Meanwhile, EPCglobal defined an ALE(Application Level Events) standard specification, which exists between RFID readers and applications, and substitutes the previous systems called Savant. In the specification internal structures and implementation technologies of ALE are not mentioned and only external interfaces are defined. This approach easies the verification of standard compliance and inter-operability of the layer. In this paper, we present the design of ALE-compliant RFID middleware systems that process RFID tag data efficiently.

최근에는 LED 조명으로 인해 조명 제어의 유연성이 높아짐에 따라 가정이나 사무공간에서 해당 공간의 목표 조도를 설정하고 현재 내부조도의 상황에 따라 자동으로 조명을 디밍하는 형태로 연구가 이루어지고 있다. 그러나 이러한 제어방식이 현재 주택용 요금제도로 운영 중인 고정요금제에서는 에너지 비용을 감소시키나, 스마트그리드에서 운영될 RTP(Real Time Pricing)에서는 요금 단계에 따라 오히려 에너지 비용이 증가될 수 있다. 이에 본 논문은 실시간 요금 단계에 따라 LED 조명의 목표 조도를 가변적으로 변화시켜 조명 에너지 비용을 최소화하고 사용자의 작업에 적합한 상황별 조도를 자동으로 제어하여 작업자에게 편리함을 제공하고자 한다. 이때 요금 단계에 따른 상황별 최저 및 최고 조도기준은 KSA 3011 및 IES를 참조하며, 최소한의 조명 에너지 사용을 위해 외부 광량을 최대한 활용하여 현재의 시간에 따라 블라인드의 Open/Close를 자동으로 서비스한다. 사용자의 상황은 PIR, Electric Powermeter, Piezoelectric 센서로부터 사용자의 위치, 가전기기 사용 유무, 착석 여부 등을 파악하고, RTP 요금에 따라 하루동안의 조명에 사용된 전력요금을 시뮬레이션한다.
