본 연구는 지방공무원들의 셀프리더십이 직무만족과 고객지향성에 미치는 영향을 경험적으로 파악하여 정책적 시사점을 도출할 목적으로 수행되었다. 그동안 행정서비스를 국민의 필요와 욕구에 맞춰 제공하기 위한 다양한 제도적 방법이 도입되어 왔지만 만족할 만한 얻지 못했다. 제도적 접근만으로는 관료들이 직무수행 행태를 고객지향적 행동으로 바꾸는데 한계가 있기 때문이다. 오랜 공무원들의 서비스 공급자 중심의 역할인식과 직무수행방식을 수요자 중심으로 바뀌는 데는 많은 시간이 필요한 것이다. 셀프리더십은 조직구성원의 자발적이고 능동적 행동을 통한 내적에너지를 업무수행에 활용하는 능력으로 조직목표달성에 긍정적 영향을 미치는 요인이다. 본 연구의 분석 결과 셀프리더십이 공무원의 고객지향성에 긍정적으로 영향을 미치는 것으로 확인되었으며 직무만족도가 매개적 역할을 수행하고 있음도 제시하였다. 행정서비스의 고객지향성을 강화하기 위해서는 제도적 통제를 받지 않아도 자기 스스로 자신의 태도와 행동을 긍정적 방향으로 바꿀 수 있도록 셀프리더십을 향상시키는 정책적 접근을 제안하였다.

This study examined what meaning East Asian women showed in their costume history through a discourse of hair adornments such as wigs and that Gache was not just a luxury decoration. In addition, we examined Gache hair trends with Eonjeun-meori (braid wraps around the entire head) in the Joseon dynasty (Korea), Gigye(旗?) hair in the Quing dynasty (China) and Mage(?) hair in the Edo period (Japan) during the $18^{th}$ and $19^{th}$ centuries. The significance of the phenomenon of East Asian Gache culture in the $18^{th}$ and $19^{th}$ centuries was analyzed from the internal desires of women. The details are as follows. First, the magnification by the hair decoration was identified with self-authority and used as a sign to express self-respect or a desire for self-esteem. The extended Gache was an external body extension to raise self-authority and increase activeness. Second, self-satisfaction through showing off was associated with a women's search for identity. There was excessive consumption to boast status, wealth and femininity, but the mania continued because women obtained psychological satisfaction by feeling that their sacrifices for the Confucian order were compensated. Third, the frenzy of Gache was accepted as a way for women to resist social regulations and find themselves as main participants in social activities. Showing their appearance in East Asian Gache culture was a way of inner self-searching and a process for women to find themselves as a social entity.

The hotel industry needs to make the competitive advantage difficult to be imitated in order to remain sustainable in competitive business circumstances. Front-line employees' service-oriented citizenship behaviors(OCBs) can be such a strength from the perspective of organizational system. With an aim of investigating the antecedents of the hotel front-line employees' service-oriented OCBs, this study proposed a theoretical framework linking authentic leadership to service-oriented OCBs with goal commitment as a mediator. A total of 260 cases without missing values have been used for the final analysis and structural equation modeling (SEM) is employed using the SPSS and AMOS 7. It was first found that self-awareness and relational transparency of authentic leadership made a significant impact on their goal commitment while balanced processing and moral perspective failed to influence them. Second. goal commitment influenced all sub-factors of service-oriented OCBs. Third, moral perspective and relational transparency of authentic leadership significantly influenced service-oriented OCBs while self-awareness and relational transparency failed to make it. Finally, goal commitment significantly makes an intervening effect for the relationship between self-awareness & service-oriented OCBs and relational transparency & service-oriented OCBs but failed to intervene the other relationships. The results provide theoretical and practical implications regarding directions of leadership styles and HR management in the hotel industry and suggestions for the further extended studies.

In this paper, we propose a new architecture of Self-Organizing Fuzzy Polynomial Neural Networks(SOFPNN) by means of genetically optimized fuzzy polynomial neuron(FPN) and discuss its comprehensive design methodology involving mechanisms of genetic optimization, especially genetic algorithms(GAs). The conventional SOFPNNs hinges on an extended Group Method of Data Handling(GMDH) and exploits a fixed fuzzy inference type in each FPN of the SOFPNN as well as considers a fixed number of input nodes located in each layer. The design procedure applied in the construction of each layer of a SOFPNN deals with its structural optimization involving the selection of preferred nodes (or FPNs) with specific local characteristics (such as the number of input variables, the order of the polynomial of the consequent part of fuzzy rules, a collection of the specific subset of input variables, and the number of membership function) and addresses specific aspects of parametric optimization. Therefore, the proposed SOFPNN gives rise to a structurally optimized structure and comes with a substantial level of flexibility in comparison to the one we encounter in conventional SOFPNNs. To evaluate the performance of the genetically optimized SOFPNN, the model is experimented with using two time series data(gas furnace and chaotic time series).

Real time fractal coding for successive QCIF 144*176 luminance images has been implemented on a 50MHz IBM 486 personal computer. To satisfy the frame encoding speed and data compression ratio, following algorithms are adopted. In order to minimize encoding time, extension SAS being not searching of domain blocks is used. for reducing the bits per pixel, conventioal 4*4 range block is extended to 8*8 range block. and range block extension decrease quality of decoded image. For improvement quality of decoded image, the paper apply quad-tree partition mothod. In order to divide **8 range block, self-simiarity is compared 8*8 range block with spatial contractive transformed 8*8 domain block. According to self-simiarity, the block is partitioned and owing to block partition, increased encoding time is minimized. According to self-simiarity of 8*8 range block and spatial contractive transformed 8*8 domain block, number of fractal factor is varied. Simultaneously with minimizing the decrement of decoded image's quality, transmittion rate and encoding time is shorted. The results enable us to process the real-time fractal coding. For the claire test image, the average PSNR was 32.4dB, 0.12 bit rates and 33ms coding time per frame.

As National Education Information Systems (NEIS) is supposed to broadly introduced all over the country, we need to understand factors that would affect its successful use. Studies regarding the NEIS have been made in terms of a social issue according to its introduction and use, however there has been only little research made in terms of the use of the system so far. Therefore, this study aims to investigate the factors that would have effect on a successful use of the NEIS. A research model of the study is based on the extended DeLone and McLean's information systems success model with two characteristics of computer self-efficacy and perceived fairness. Based on the survey data from 168 subjects, the present study performs SEM analysis with PLS. The results show that perceived usefulness and computer self-efficacy improves the user satisfaction. However, the user' satisfaction does not cause system characteristics- system quality, information quality, service quality -and perceived fairness not effect. The study provides characteristics which can effectively and smoothly introduce the NEIS for its successful use on the upcoming full scale execution on the NEIS.

The focus of this paper is given to the investigation of mechanical properties of steel fibre reinforced self-compacting concrete after being exposed to fire. The research programme covered tests of two sets of beams: specimens subjected to fire and specimens not subjected to fire. The fire test was conducted in an environment mirroring one of possible real fire situations where concrete surface for an extended period of time is directly exposed to flames. Micro-cracking of concrete surface after tests was digitally catalogued. Compressive strength was tested on cube specimens. Flexural strength and equivalent flexural strength were tested according to RILEM specifications. Damages of specimens caused by spalling were assessed on a volumetric basis. A comparison of results of both sets of specimens was performed. Significant differences of all tested properties between two sets of specimens were noted and analysed. It was proved that the limit of proportionality method should not be used for testing fire damaged beams. Flexural characteristics of steel fibre reinforced self-compacting concrete were significantly influenced by fire. The influence of fire on properties of steel fibre reinforced self-compacting concrete was discussed.
