The purposes of this study were to reevaluate urban traditional houses and to propose direction for the conservation and utilization of urban traditional houses in a way of maintaining historical landscape rather than the value of urban traditional houses as components in expanded urban structure. For these purposes, we identified the characteristics of conservation and utilization of urban traditional houses by representative cases and analyzing them exhaustively, and suggested problems in the cinservation and utilization of traditional houses and solution for them. The current conservation system for Urban Traditional House in the Bukchon area is applied to non-residential Urban Traditional House differently according to the owner's consciousness of conservation because there is no support system for non-residential Urban Traditional House. Accordingly, there should be standardized criteria to maintain the landscape of the Bukchon area in terms of beauty formed by the elevation of Urban Traditional House and the continuity of roofs while accommodating various functions. As in total conservation or partial conservation, the interior remodeling of individual houses may be allowed but the three-dimensional external appearance composed of the outer walls, fences and roofs of Korean-style houses should be repaired and improved in a way of maintaining the image. In order to utilize Urban Traditional House in the Bukchon area, plans should be made in consideration of its location, historicity and tradition. We may expect the utilization of traditional cultural facilities and their surrounding areas as alternative cultural spaces. Such use of individual Urban Traditional House should be extended by linearly and areally and suggest the direction of conservation and utilization.

Due to the potential growing capability that reflects future value, the market value of internet business companies (IB) are still evaluated high although major players like Amazon continuously suffer losses. Then, how do investors valuate the potential growing capabilities given that traditional financial/accounting based valuation approaches seem to be inappropriate for IB. This study attempts to provide an answer to this issue. We, therefore, analyzed the predictability of various accounting and non-accounting variables for IB value. These include book value, net income, unique visitors, page view, reach rate, public float and institutional holdings. Because of being in infant stage and difficulties in obtaining necessary web traffic data, sample of 20 pure IB were selected from Korea Stock Exchange Market, KOSDAQ, and informal market. The results of this study showed that web traffic date had the strongest relationship with IB value. In particular, unique visitors and reach rate were found to be best predictors for IB value while page view was reasonable indicator. Interestingly, net income was not found to related to IB value. This calls for an attention to the typical characteristics of IB that my hinder the usage of traditional valuation approaches for IB. Another results revealed that none of both public float and institutional holdings was significantly associated with IB value, indicating market’s supply-demand factors were less important than traffic information.

Unlike the traditional displacement type vessels, the high speed planing crafts are supported by the lift forces which are highly non-linear. This non-linear phenomenon causes their motions in an irregular seaway to be non-Gaussian. In general, it may not be possible to express the probability distribution of such processes by an analytical formula. Also the process might not be stationary or ergodic in which case the statistical behavior of the motion to be constantly changing with time. Therefore the extreme values of such a process can no longer be calculated using the analytical formulae applicable to Gaussian processes. Since closed form analytical solutions do not exist, recourse is taken to fitting a distribution to the data and estimating the statistical properties of the process from this fitted probability distribution. The peaks over threshold analysis and fitting of the Generalized Pareto Distribution are explored in this paper as an alternative to Weibull, Generalized Gamma and Rayleigh distributions in predicting the short term extreme value of a random process.

Traditional intermediaries refer to service providers such as travel agents, real estate brokers, job agencies and insurance agents which matching services for buyers and suppliers in a traditional market. The introduction of Electronic commerce resulted in the automation of many tasks provided by intermediaries and seemed to eliminate the role of many traditional intermediaries, which is called disintermediation. However, depending on their market power, traditional intermediaries either will be disintermediated or fill new roles by providing added value and assistance, which is called reintermediation. According to the research of Alina M. Chircu et al. there are three conditions for reintermediation for traditional intermediaries. Three conditions are weak appropriability of EC innovations, ownership of co-specialized assets for both market intermediation and EC innovations and economies of scale. Besides these three reintermediation conditions, we hypothesize that leveraging BPO can be a suitable strategy for traditional intermediaries to be transformed into reintermediaries. Business Process Outsourcing (BPO) is the leveraging of technology or specialist process vendors to provide and manage an organization's critical and/or non-critical enterprise processes and applications. This paper will investigate the relationship between above reintermediation conditions including BPO and reintermediation.

Purposes: Lung cancer is prevalent worldwide and improvements in timely and effective diagnosis are need. Pentraxin-3 as a novel serum marker for lung cancer (LC) has not been validated in large cohort studies. The aim of the study was to assess its clinical value in diagnosis and prognosis. Methods: We analyzed serum PTX-3 levels in a total of 1,605 patients with LC, benign lung diseases and healthy controls, as well as 493 non-lung cancer patients including 12 different types of cancers. Preoperative and postoperative data were further assessed in patients undergoing LC resection. The diagnostic performance of PTX-3 for LC and early-stage LC was assessed using receiver operating characteristics (ROC) by comparing with serum carcinoembryonic antigen (CEA), cytokeratin 19 fragments (CYFRA 21-1). Results: Levels of PTX-3 in serum were significantly higher in patients with LC than all controls. ROC curves showed the optimum diagnostic cutoff was 8.03ng/mL (AUC 0.823, [95%CI 0.789-0.856], sensitivity 72.8%, and specificity 77.3% in the test cohort; 0.802, [95%CI 0.762-0.843], sensitivity 69.7%, and specificity 76.4% in the validate cohort). Similar diagnostic performance of PTX-3 was observed for early-stage LC. PTX-3 decreased following surgical resection of LC and increased with tumor recurrence. Significantly elevated PTX-3 levels were also seen in patients with non-lung cancers. Conclusions: The present data revealed that PTX-3 was significantly increased in both tissue and serum samples in LC patients. PTX-3 is a valuable biomarker for LC and improved identification of patients with LC and early-stage LC from those with non-malignant lung diseases.

In construction industry, the term 'procurement' is considered as a project based job where clients and contractors are always keen to observe performance indicators. These indicators represent financial and non-financial efficiency of project activities. Among these, the monitoring of financial indicators such as cost monitoring is an ongoing process and its importance cannot be undermined during the project life cycle. It can be monitored by using traditional approach of direct reporting of actual cost against budget. However, the comparison of budget versus actual spending does not indicate the worth of the work which is completed at any given time. This approach does not represent the true cost performance of the project. Because of these limitations, this paper discusses the applications of Earned Value Analysis (EVA) for cost monitoring of construction projects in Malaysia. Besides traditional approach, EVA is a three-dimensional approach that compares three cost indicators i.e. the budgeted value of work scheduled with the earned value of physical work completed and the actual cost of work completed. Therefore, cost monitoring by EVA is an objective measure of actual work performed. This paper uses a case study, an example application of EVA as a cost monitoring tool. This case study reaffirms the benefits of using EVA for project cash flow analysis and forecasting.

Meat contains high-value protein compounds that might degrade as a result of oxidation and microbial contamination. Additionally, various pathogenic and spoilage microorganisms can grow in meat. Moreover, contamination with pathogenic microorganisms above the infectious dose has caused foodborne illness outbreaks. To decrease the microbial population, traditional meat preservation methods such as thermal treatment and chemical disinfectants are used, but it may have limitations for the maintenance of meat quality or the consumers acceptance. Thus, non-thermal technologies (e.g., high-pressure processing, pulsed electric field, non-thermal plasma, pulsed light, supercritical carbon dioxide technology, ozone, irradiation, ultraviolet light, and ultrasound) have emerged to improve the shelf life and meat safety. Non-thermal technologies are becoming increasingly important because of their advantages in maintaining low temperature, meat nutrition, and short processing time. Especially, pulsed light and pulsed electric field treatment induce few sensory and physiological changes in high fat and protein meat products, making them suitable for the application. Many research results showed that these non-thermal technologies may keep meat fresh and maintain heat-sensitive elements in meat products.

Traditional Korean Medicine and Taoism think of the importance of a life nurturing for one's health and longevity. However, for a life nurturing, Traditional Korean Medicine aims at a person living up to one's natural life span. Taoism lays importance on ascending up to the sky to be a Taoist hermit with supernatural powers. Therefore, they both differ in the pursuit of their goals and their methods in doing respectively. In this study we have shown similarities and differences in the meaning and ways to practice su-seung-hwa-gang (body water rising and heat falling) which Traditional Korean Medicine and Taoism regard highly as a means of the practice of a life nurturing. Su-seung-hwa-gang is a concept that both Traditional Korean Medicine and Taoism set a high value on and at the same time it is a concrete method of a life nurturing demonstrating the possibility of 'non-disease treatment' through the active efforts of Traditional Korean Medicine.

The rapid development of the fashion industry in contemporary society has also caused various problems such as environmental pollution, material excess, and spiritual poverty. Accordingly, traditional Chinese Taoist aesthetics can solve the spiritual poverty that people are facing today, and the spiritual pursuit of returning to innocence. This study focuses on the works of first generation Chinese designer Ma Ke as an example to discuss the embodiment and application of Taoist aesthetics. The results are as follows: First, Ma Ke's works emphasize the value of handicraft through traditional handcrafting and natural fibers, which reflect the beauty of simplicity and the non-action of Taoist aesthetics. Second, the works acknowledge nature by using natural materials and retaining their original appearance, which embodies Taoist aesthetics of the beauty in non-action and living in harmony with nature. Third, the collections reflect a critical attitude toward the fashion industry and consumer culture by rethinking consumerism and advocating environmental protection, thus propagating the beauty in simplicity and the harmonious life with nature in Taoism aesthetics. In conclusion, Ma Ke's designs incorporating sustainability and handicraft exhibit the core features of Taoist aesthetics, including the beauty in simplicity, non-action, and living in harmony with nature while exploring the relationship between modernity and tradition, man and nature, and handicraft and fashion. This research can contribute to understanding Ma Ke's works in promoting critical thinking about the fashion industry through Taoist aesthetics.
