Wireless Internet, created through the merging of mobile communication with Internet technology, provides the advantage of mobility, but the restrictions of the mobile environment are deterring it from growing into a mass public service. Of the restricting factors of the wireless environment, narrow memory space creates the disadvantage of not being able to manage resources in mobile devices efficiently Because there is a limit to obtaining sufficient memory space from hardware made with consideration of portability, future devices will need to have a platform design with storage area extended from internal storage to external storage space. In this paper, we present a mobile agent that extends the memory space from only the inside of a mobile device to an external server making it possible to use data by on-line Run-time, and can also manage internal files efficiently. We have designed and implemented a RMS(Resources Management System) as a realization. Devices using the proposed RMS will be able to apply extended processes with the 'Mobile Space Extension' and will be benefited with optimal memory space through efficient internal file management.

Ethernet has been given a greater attention recently due to tendency of unifying most of transmission technique to ethernet. This paper studied the design of MAC which contains high layer interface, transmit engine, flow control block, receive engine, reconciliation sublayer, configuration block, statistics block, and XGMll interface block. Performance evaluation was performed using C language for 10cbps ethernet Data Link to design the optimum hardware, then internal FIFO and initial parameters were evaluated. When offered load is $95\%$, the size of the internal FIFO is required 512-word. When offered load is $97\%$, the size of the internal FIFO is required 1024-word. Based on the result of performance evaluation, MAC was designed in VHDL Language and verified using simulator. MAC core that processes 64-bit data, operates at 168.549MHz and hence supports the maximum 10.78Gbps. The designed MAC core is applicable to an area that needs a high-speed data processing of 10Gbps or more.

In order to investigate the meanings and bases of transforming theories of diseases(病傳論), several relevant theories were collected from medical books since . The outside-to-inside changing process(pyoree jeon) was the fundamental pattern in febrile diseases regardless of slang han and wen bing after Han dynasty. But in case of numb disease the three exogenous pathogenic factors of wind, cold and dampness got into each viscera through five tissues like skin, vessesl, flesh, tendons, bones respectively. It was called corresponding changing process(sanghap jeon) here. The pathogenic changing process(byungsa jeon) had complicated details to explain pathologic processes, but could give useful informations on evaluating relative strength of pathogens and tendency ahead. The changing process of diseases of internal injuries were explained in case of emotional distress which is outbroken abruptly didn't follow regular order of viscera-emotion relations. So it was named random changing process(bulcha jeon) after 's usage. And marasmus and asthenic disease followed top-to-down or down-to-top changing process(sangha jeon) based on . There are many types of changing process of diseases between viscera and viscera or viscera and bowels like generation changing process, restriction changing process, changing process between couple, changing process of mutual transmission based on attributions of each element by the theory of 5 phases(五行論). And changing process to a neighbor doesn't have any special relations within two organs but has anatomical contiguity and physiological continuity between them. The transforming theories of diseases bring forth useful understanding on comings and goings of pathogenic factors and tendency and prognosis of disease, so they are needed to be taught in the course of pathology class.

This paper presents inference methods for inner operations of a multi-server queue when historical data are limited or system observation is restricted. In a queueing system analysis, autocorrelated arrival and service processes increase the complexity of modeling. Accordingly, numerous analysis methods have been developed. In this paper, we introduce an inference method for specific situations when external observations exhibit autocorrelated structure and and observations of internal operations are difficult. We release an assumption of the previous method and provide lemma and theorem to guarantee the correctness of our proposed inference method. Using only external observations, our proposed method deduces the internal operation of a multi-server queue via non-parametric approach even when the service times are autocorrelated. The main internal inference measures are waiting times and service times of respective customers. We provide some numerical results to verify that our method performs as intended.

This study explored the internal world through sandplay therapy for an elementary school boy who had social and emotional difficulties of poor peer relations, anxiety and withdrawal. This study examined the changing processes of sandboxes, how a boy expressed his internal world by the content themes in sandplay according to Turner (2009) based on analytical psychology and sandplay theories. There were 72 sessions. The initial phase was 1-6 (The beginning of war) expressing confusing wars as the start of a long internal journey. The intermediate phase was 7-55 (Struggle), dividing by phase I 7-18 (Hero's fight I), phase II 19-36 (Hero's fight II), phase III 37-48 (Seeking for a male identity), and phase IV 49-55 (Centering). The client identified himself as a teenaged hero and expressed the conflict between good and bad, between death and rebirth and struggled for seeking treasures in the fight of heroes. He found identity as a male by finding a sense of existence, establishing order in the middle of confusion, and expressing strong and rational masculinity. The final phase was 56-72 (The winner of the struggle). In the fights repeating, he expressed an adventurous and positive male energy such as racing, speed contests and a union in the opposites of hero and heroine as well as the birth of a new conscious. This study provides a basic knowledge of educational guidance in school and counseling fields by expanding the understanding of a boy's unconsciousness.

Since the beginning of 2015, corporate social responsibility (CSR) models have been changing in connection with the trend towards the transition of joint value creation of corporate activities and consideration of stakeholders' interests. The purpose of the academic paper lies in empirically studying the current practice of social responsibility of transnational corporations (TNCs). The research methodology has combined the method of qualitative analysis, the method of cases of agricultural holdings in emerging markets within the framework of resource theory, institutional theory and stakeholders' theory. The results show that the practice of CSR is integrated into the strategy of sustainable development of TNCs, which determine the methods, techniques and forms of communication, as well as areas of stakeholders' responsibility. The internal practice of CSR is aimed at developing norms and standards of moral behaviour with stakeholders in order to maximize economic and social goals. Economic goals are focused not only on making a profit, but also on minimizing costs due to the potential risks of corruption, fraud, conflict of interest. The system of corporate social responsibility of modern TNCs is clearly regulated by internal documents that define the list of interested parties and stakeholders, their areas of responsibility, greatly simplifying the processes of cooperation and responsibility. As a result, corporations form their own internal institutional environment. Ethical norms help to avoid the risks of opportunistic behaviour of personnel, conflicts of interest, cases of bribery, corruption, and fraud. The theoretical value of the research lies in supplementing the theory of CSR in the context of the importance of a complex, systematic approach to integrating the theory of resources, institutional theory, theory of stakeholders in the development of strategies for sustainable development of TNCs, the practice of corporate governance and social responsibility.

This study was designed to investigate the protective effect of Bojungmyunyuk-dan(BJMY-Dan) on the cisplatin-induced cytotoxicity of primary rat astrocytes. BJMY-Dan is an oriental herbal prescription for its ability to recover protective effects against anti-cancer chemotherapies. After astrocytes were treated cisplatin, MTT assay was performed for cell viability test. To explore the mechanism of cytotoxicity, I used the several measures of apoptosis to determine whether this processes was involved in cisplatin-induced cell damage in astrocytes. Also, astrocytes were treated with BJMY-Dan and then, followed by the addition of cisplatin. Cisplatin decreased the viability of astrocytes in a dose and time-dependent manner. BJMY-Dan increased the viability of astrocytes treated cisplatin. Astrocytes treated cisplatin were revealed as apoptosis characterized by nuclear staining and flow cytometry. BJMY-Dan protected astrocytes from cisplatin-induced nuclear fragmentation and chromatin condensation. Also, caspase-3 and caspase-9 proteases were activated in astrocytes by cisplatin. BJMY-Dan inhibited the activation of caspase proteases in cisplatin-treated astrocytes. Cleavage of [poly(ADP-ribose) polymerase](PARP) was occurred at 12hr after treatment of cisplatin in astrocytes. BJMY-Dan recovered the cleavage of PARP in cisplatin-treated astrocytes. Also, BJMY-Dan inhibited the activation of pro-apoptotic factor, Bak by cisplatin. Lastly, astrocytes stained with JC-1 and Rhodamine 123 were photographed by fluorescence microscope to visualize changes of mitochondrial membrane permeability transition(MPT) during treatment with cisplatin for 24hr. BJMY-Dan recovered the change of MPT by cisplatin in astrocytes. According to above results, BJMY-Dan may protect astrocytes from cytotoxicity induced by chemotherapeutic agents, including cisplatin.

The question-"How fast a electron tunnels a potential barrier?" looks like simple, but is controversy for more than 40 years. Because "tunneling" involves complicated internal processes and its definition is ambiguous. Recent experiments showed that the phase time is the best model of tunneling time among other times-for example, dwell time, Larmor clock time etc. In this paper, we simulated the tunneling time for Gaussian wave packet by program InterQuanta and compared with the phase time. In particular we focused on the effect of wave packet spreading in momentum space(or real space) which is not expressed by the phase time formula.

Logistics in a supply chain network has become an important operational strategy in a competitive market. A number of internal and external risks involved in the logistics operations in a company tend to create problems in fulfilling customer orders. This research presents how ERM (enterprise risk management) can be used to identify, assess, and control logistics risks. An electronic company's logistics activities were used as an industry case to demonstrate a way to identify and assess risks surrounding global logistics function. This paper has further presented action plans to mitigate the impact of the risks that occur.
