  • Today, information technologies have been applied to operations in container terminals, and it is possible to collect operational log data due to development of equipment and operations technology. Terminal operators are collecting event log data and try to figure out the way of resolving operations problems. Operators want to analyze event logs to determine the causes of the operation problems, but it can hardly be done manually. In this paper, we suggest a formal framework to evaluate performance measures using the collected log data of operations in container terminals. The proposed formal framework supports different container terminal layout, operational processes, and equipment. Our formal framework is composed of specification of terminal layout, log data, workflow, statistics, and report, based on the concept of container handling objects. For validation of our framework, we have implemented a terminal performance analysis system based on the proposed framework.

  • This study aims to measure stretch rate of standard weight in the $2{\times}1$ rib stitch and $2{\times}2$ rib stitch, and to apply features of rib stitch to the knit pattern. The reviewer examined the sample knit for test with 100% wool, $2/48's{\times}2$, 12 gauge, and then made knit patterns and sample clothes for test considering stretch rate of standard weight of 10gf, 15gf, 20gf, 25gf based on the results from the former test, and finally estimated the try-outs for sample clothes. This study came out with the following results: From the functional estimate of knit patterns made by standard stretch rate of each stitch, the 20gf weight sample clothes of $2{\times}1$ and $2{\times}2$ rib stitchs were in high estimate. For the bust, B/4~ -4.6cm knit pattern was made of $2{\times}1$ rib stitch, B/4~5.3cm of $2{\times}2$ rib stitch. In conclusion, because $2{\times}1$ and $2{\times}2$ rib stitchs has the much higher stretch rate in the direction of the course than $0{\times}0$ ad $1{\times}1$ rib stitchs, high stretch rate of standard weight should be applied to the case of making knit wear. It is expected that this will lead stable sizing and measurement system when used in making knit patterns, and satisfy knit wearers' various needs.

  • This study aims to measure stretch rate of standard weight in the direction of the knit stitch course by the difference in the way of weaving rib stitch, the most elastic stitch of all the knit stitches and to apply features of rib stitch to the knit pattern. The reviewer examined the sample knit for test with 100% wool, 2/48's 2, 12 gauge, and then made knit patterns and sample clothes for test considering stretch rate of standard weight of 10gf, l5gf, 20gf, 25gf based on the results from the former test, and finally estimated the try-outs for sample clothes. This study came out with the following results. From the functional estimate of knit patterns made by standard stretch rate of each stitch, the l5gf weight sample clothes of 0×0 and 1×1 rib stitches looking similar to plain stitch. For the bust, B/4-1.0㎝ knit pattern was made of 0×0 stitch, B/4-1.2㎝ of 1×1 rib stitch. In conclusion, because rib stitch has the much higher stretch rate in the direction of the course than other stitches, low stretch rate of standard weight should be applied to the case of making knit wear. It is expected that this will lead stable sizing and measurement system when used in making knit patterns, and satisfy knit wearers' various needs.

  • This study is to investigate the previous cases of plural eclecticism through the works of Vivienne Westwood, who contributed to the spread of innovative and eclectic English fashion out to the world as well as to review plurality and its phenomena since the 20th century more systematically. In terms of research methodology, the phenomena of plural eclecticism were examined from social and cultural perspectives, whereas bibliographic research and case study were performed for the phenomena of eclecticism in fashion. From the perspective of plural eclecticism, the results from analyzing the works of Vivienne Westwood by the divisions of temporal eclecticism, spatial eclecticism, and contingent eclecticism are described in the following. First, Vivienne Westwood emphasized historicism tendency of temporal eclecticism. Her efforts to try to modernize history went beyond ages and social classes including men's clothing, prostitutes' costumes, craft items, and dresses for royal family. Second, her spatial eclecticism was reflected on the first collection themes inspired by the American Indians or borrowed from the names of Voodoo in the Tropics. Finally, infra-fashion as an expression of contingent eclecticism of Vivienne Westwood's works can be interpreted as plural eclecticism which shows contingent eclecticism and historic eclecticism at the same time. This study aimed at proving preceding implications concerning recent plural eclecticism through the analysis of the works of Vivienne Westwood who tried a radical design of plural eclecticism in an effort to modernize the tradition of England in the circumstances where a number of trends and styles exist together, with their own uniqueness and values.

  • This paper describes a hybrid QoS guarantee scheme for high quality audio streaming services on the Internet. The continuous playback of the audio data requires the isochronous transmission of the audio data packet through the Internet. In order to retain the QoS at the ultimate destination (client) as the same as servers provide, the transmission protocols should consider the error conditions such as packet loss, and out of order delivery. Generally, the protocols supporting the transmission of continuous media data do not try to recover the errors. The protocols are working somehow for the toll quality multimedia streaming services, but rot for the high quality streaming services, such as the DVD sound/music payback. The hybrid QoS guarantee scheme includes the three mechanisms to overcome the problem. The selective retransmission for the lost packet, the adaptive buffering at client-side, and the adaptive transmission rate at server-side are totally adopted to recover the packet loss with the minimal overhead, to prevent from the buffer starvation during the retransmission, and to maintain the isochronous transmission even after the retransmission. The experiments have shown good results for the high Quality audio streaming services on the Internet.

  • It is generally known that handoff delay degrades the QoS by packet drop, packet delay and jitter. Moreover. handoff highly effects on QoS in beyond 3G system because not only micro cells for achieving high capacity and fast moving nodes induce the frequent handoff but also hard handoff must be carried out in OFDM system. Therefore, study on a handoff algorithm for guaranteeing QoS is required. Related works on handoff for beyond 3G system mainly focused on reducing the L3 handoff delay or packet loss. That is, these schemes try to compensate L2 delay rather directly eliminate it. However, remained 1.2 delay degrades QoS, especially delay-sensitive realtime traffic. Therefore, we proposed the seamless handoff algorithmwhich can minimize the L2 handoff delay.

  • Recently, client requirements concept is an important issue related to many effects of firms. Especially, if we think that apartment is given a great deal of national construction industry, it is requested that we should try to improve apartment quality with various methods of client requirements survey and reflecting those on apartment project. The technique searching and applying client requirements to apartment project is requested for that and ROQ(Return On Quality) process connected to QFD(Quality Function Deployment) is a technique which is used in manufacturing industry and help to make money by rising client satisfaction with searching clients requirements, and applying this to quality improvement program. In this study apartment quality management development is suggested through using ROQ process. For this customer interview research and FGI(Focus Group Interview) was carried out and clients requirement was analyzed with this. Then quality improvement program applicable to developing a new apartment product was established with specialist monitoring. A new apartment quality management development plan is prosed with this process.

  • The 8-VSB modulation, the transmission standard for the terrestrial digital television(DTV) of the Advanced Television Systems Committee(ATSC), suffers from multipath fading because it conveys information on the amplitude. To solve this problem, decision feedback equalizers(DFE's) have been commonly used in terrestrial DTV receivers. However, under severe channels, such as a 0 dB ghost channel or a single frequency network (SFN) channel, the DFE shows unstable convergence due to the error propagation caused by decision errors. Instead of unstable time-domain DFE schemes, by proposing a frequency-domain direct-inversion equalization method, we try to guarantee stable equalization and achieve low symbol error rates. To secure the existence of a channel inverse, channel-matched filtering and noncausal filtering are carried out prior to equalization. Simulation results show that the proposed method performs much better than existing DFE schemes in terms of both the stability and the symbol error rate.

  • Recently, the long-term care insurance for the elderly was carried out according to the elderly is increased rapidly and the formation of sympathy that a nation and society try commonly to share health and welfare promotion of the elderly. The purpose of this study is to analyze the present status of nursing home after that the long-term care insurance is enforced in chungcheongbuk-do and to utilize as basic data. The study limited its survey to those facilities that refer to the Ministry of Health and Welfare data, that had the capacity of more than 50 people. The result are as followings. Firstly, most of the nursing home were located on the outskirts of the city. But it must be constructed in the city center if the recent deinstitutionalization trend is reflected. Secondly, notwithstanding the provisions of the Elderly Welfare Law, if the Livability and amenity are considered, the plan of a single or a twin room is needed. The ondol(溫突) system bedroom for the safety of the elderly had to be planned and for the color planning of a bedroom, a heating, the furniture, the form of a door, corridors, etc. should be partly improved. The fastener in which it is appropriate for the main exit, a stair, an elevator, the lighting device, and etc. is needed and the installation of a wandering path for the dementia patient and etc. is required. Thirdly, most of the dining room arranged on the first floor but it is not nearly used and it used for employee or the other use. Therefore, we have to consider the system in which it can deliver the meal to a bedroom. If the smell of the elderly and etc. is considered, the sufficient height of the floor should be reflected for the ventilation equipment. Lastly, The improvement of the existing law are required.
