Recently, both the integration of product data during design and production and the effective management of information during full lifecycles have attracted attention from shipyards and ship owners as a result of recycling regulations and a desire for efficient operations. Generally, PLM (Product Lifecycle Management) supports a collaborative environment during the BOL (Beginning of Life) stage, while an ALM (Asset Lifecycle Management) system provides all of the information required to maintain, overhaul, and discard/recycle all or part of a vessel during the MOL (Middle of Life) and EOL (End of Life) stages. The main goal of this paper is to suggest the fundamental configuration of a PALM (Product Asset Lifecylce Management) system and a method that can be used to utilize a marine vessel's lifecycle information during the MOL, emphasizing the maintenance information during the middle of life. The authors also suggest a PALM system configuration in which lifecycle information can be collected by a PEID (Product Embedded Information Device) integrating a microcomputer, sensors, and wireless network communication. Through a prototype PALM system, the suggested features and PALM system configuration are implemented.

Hong, You-Son($1452{\sim}1529$) overcame his suffering, caused by his low social standing, through Taoism. Hong, You-Son could be infatuated with Taoism because Taoism was still spread all over the country in early Chosun dynasty and in more permissive atmosphere than the atmosphere after the Japanese invasion of Korea in 1592. Therefore, Taoist health prevention, not religion, reflecting theory of Taoist hermit and wishing for perennial youth and long life was prevalent among the intellectual class in that period. In addition, it was very fascinating idea for Chosun intellectual class to prevent health with practice because medicine was not developed in that period. The importance of his health prevention was vitality ; he insisted that people can get health and long life with it and need mind practice to discard greed of this life. His advocacy was agreed with Kim, Si-Seup, and Chung, Ryum, the members of Danhak School, and his health prevention became a base for medicine developments preventive medicine. Hong, You-Son seemed to use Taoism not to avoid temporally, but to overcome his suffering, and furthermore, find out self identity. He became one of major members of Danhak School because the ideas of Taoism such as accomplishing health and long life with self practice and achieving self satisfaction with discarding utilitarianism was fitted for conflict mind of Hong, You-Son. Taoist ideas were reflected in his poetry and his everyday life ; he identified a Taoist hermit with Himself in his poetry and acted like a hermit in his everyday life.

In this paper, we implement a high-speed swatch tilth the function for label integration to enhance the expansion of networks using the label space of routers efficiently on MPLS over ATM networks. We propose an appropriate hardware structure to support the VC-merge function and differentiated services simultaneously. In this paper, we use the adaptive congestion control method such as EPD algorithm in carte that there is a possibility of network congestion in output buffers of each core LSR. In addition, we justify the validity of the proposed VC-merge method through simulation and comparison to conventional Non VC-merge methods. The proposed VC-merge capable switch is modeled in VHDL. synthesized, and fabricated using the SAMSUNG 0.5um SOG process.

This paper proposes a method for detecting edge using an evolutionary programming and a momentum back-propagation algorithm. The evolutionary programming does not perform crossover operation as to consider reduction of capability of algorithm and calculation cost, but uses selection operator and mutation operator. The momentum back-propagation algorithm uses assistant to weight of learning step when weight is changed at learning step. Because learning rate o is settled as less in last back-propagation algorithm the momentum back-propagation algorithm discard the problem that learning is slow as relative reduction because change rate of weight at each learning step. The method using EP-MBP is batter than GA-BP method in both learning time and detection rate and showed the decreasing learning time and effective edge detection, in consequence.

Background: The development of diagnostic techniques and an awareness of health examinations can bring about an early diagnosis of lung cancer. However, appropriate postoperative management and adjuvant chemotherapy remain under debate in postoperative therapeutic strategy. The present study was conducted to assess the clinicopathologic factors that influence recurrence and prognosis after complete resection of lung cancer. Methods: The present study analyzed 62 patients with lung cancer who underwent complete resection of diagnosed adenocarcinoma between 1994 and 2007. In addition to conventional factors, which include staging factor and histological evaluation, the present study also performed univariate and multivariate analyses to consider claudin, a cell adhesion molecule, as a prognostic factor by immunohistochemical staining. Results: There was no correlation between conventional factors, including lymphatic and vascular invasion, and recurrence. However, there was a significant correlation between high expression of claudin 4 and cancer recurrence. In particular, there was a correlation between high expressions of claudin 1, 4, and 5 and a reduction of disease-free survival. Conclusion: Increased expressions of claudin 4 were negative prognostic factors in adenocarcinoma of the lung and thus could be used to identify high-risk patients for adjuvant chemotherapy, even if they had early-stage lung cancer. The present findings collectively suggest that consideration of claudin as a prognostic factor in the active postoperative treatment in patients at high risk will lead to better therapeutic outcomes with fewer side effects.

Ecklonia cava is a common edible brown algae that is plentiful in Jeju Island of Republic of Korea. Polyphenols from E. cava have strong anti-inflammatory activity. However, a large number of the by-products from E. cava processing are discarded. In the present study, to utilize these by-products, we assessed the anti-inflammatory activity of the polyphenol-rich fraction (PRF) from E. cava processing by-product (EPB) in lipopolysaccharide (LPS)-induced RAW264.7 macrophage cells. Four compounds, namely eckol, eckstolonol, dieckol, and phlorofucofuroeckol-A, were isolated and identified from PRF. We found that PRF suppressed the production of nitric oxide (NO), inducible nitric oxide synthase, and cyclooxygenase-2 in the LPS-induced cells. Furthermore, the protective effect of PRF was investigated in vivo in LPS-stimulated inflammation zebrafish model. PRF had a protective effect against LPS-stimulated toxicity in zebrafish embryos. In addition, PRF inhibited LPS-stimulated reactive oxygen species and NO generation. According to the results, PRF isolated from EPB could be used as a beneficial anti-inflammatory agent, instead of discard.

NIPS(Network Intrusion Prevention System) is in line at the end of the external and internal networks which performed two kinds of action: Signature-based filtering and anomaly detection and prevention-based on self-learning. Among them, a signature-based filtering is well known to defend against attacks. By using signature-based filtering, intrusion prevention system passing a payload of packets is compared with attack patterns which are signature. If match, the packet is discard. However, when there is packet delay, it will increase the required pattern matching time as the number of signature is increasing whenever there is delay occur. Therefore, to ensure the performance of IPS, we needed more efficient pattern matching algorithm for high-performance ISP. To improve the performance of pattern matching the most important part is to reduce the number of comparisons signature rules and the packet whenever the packets arrive. In this paper, we propose an improve signature hashing-based pattern matching method. We use tuple pruning algorithm with Bloom filters, which effectively remove unnecessary tuples. Unlike other existing signature hashing-based IPS, our proposed method to improve the performance of IPS.

This study aimed to investigate the evaluation of firefighting gloves and the behavior regarding their usage, of firefighting officials in Seoul, using a questionnaire. Responses from a total of 270 firefighters who are responsible for putting out fires or undertaking rescue works in Seoul were analyzed. As per the findings, the firefighters considered ease of hand operation and fire/flame protection as the most important performance factors for firefighting gloves, and they were satisfied with the supply status of the gloves. The average number of firefighting gloves currently owned by the firefighters was 2.6 ± 0.8 pairs. Thirty-nine percent of the respondents said that their firefighting gloves lasted, with maintained performance, for more than six months and less than a year, and when asked how they handled the gloves with degraded performance, 46% of them said that they would discard them. Sixty-eight percent of the respondents said that they used the most recently developed and supplied gloves, which they considered as the most satisfying gloves and which they mainly used these days. Respondents were highly satisfied with the fire/flame protection performance of their firefighting gloves, but were less satisfied, however, with the glove fit. These results suggest that there has been a significant improvement in the overall performance level and supply status of the firefighting gloves. Given the current situation, careful considerations with flexible approaches are needed on the current firefighting gloves size system as well as on the personal protective equipment maintenance and management scheme.

With the advent of multicultural society, many countries have come to the point of considering a fundamental revision or review of their previously established national identity and social constitution principles. This situation often generates conflicts and controversies between advocates of tradition and promotors of multiculturalism. In this article we will look at the case of France and Brazil and discuss how these two countries maintain, discard or fundamentally modify their traditional social integration model in the face of the multicultural challenges(racism, racial discrimination and integration/coexistence of immigrants of different cultural backgrounds), and examine the controversial aspects surrounding it. In particular, focusing our eyes on racial/ethnic statistics debates in both countries, we will try to compare the cases between that of adoption of multicultural alternative model(Brazil) and the case of rejection/retention(France) to find out some political meanings imbedded in those cases.

This study aimed to investigate the influence of fashion lifestyles and consumption values on the difficulty of discarding unused fashion products. To achieve this purpose, this study surveyed female consumers aged 20s-50s to gain empirical analysis in July 2018. Data were analyzed for 236 subjects who were selected through online and offline sampling. The results were as follows. First, consumers tend to have difficulties discarding unused fashion goods. Consumers that have a higher income tend to have greater difficulty when choosing to discard items. Factors influencing the difficulty in discarding items were emotional attachment, usefulness in the future, economic value, and the lack of organizing skills. Usefulness in the future and the lack of organizing skills are the most significant factors influencing the discarding difficulty. Second, discarding difficulty had a significant relationship with fashion lifestyle, indicating that consumers seeking a fashion lifestyle that purchase more expensive brands tend to have more difficulty when discarding items. Third, each factor had a meaningful relationship with fashion goods consumption values. Those pursuing conspicuous value showed a greater difficulty discarding items due to emotional attachment, economic value, and lack of organizing skills. Pursuance of situational value showed a higher discarding difficulty than economic value factors. Pursuance of practical value showed a higher difficulty than both usefulness in future situations and economic value factors. Pursuance of differentiation value showed a higher discarding difficulty than emotional attachment and usefulness in the future factor. This study will help understanding consumers psychological mechanisms that experience difficulty in terms of the discarding of unused fashion goods.
