All living things including human being consist of soul(spirit) and body. Soul is the root of a life and body frames it. I wrote this paper to tell how internal injury due to endogenous etiological factors and affection due to exogenous pathogenic factors, affect the internal organs and the external bodily from. This paper begins with description of the patterns of disharmony of the internal organs. General disorders of each Five-Jang(五藏) an be classified into two types of soul and body. The Liver and the Heart which lead changing to Yang(陽) of vital energy, have close relationship with spiritual symptoms because spirit is related to Yang. The Lung, Kidneys, the Spleen which lead changing to m(陰) of vital energy, mainly connected with physical disorders because body is relatively close to m. The Five-Jang are ruled by the Five-Phases(五行) system and cause troubles with Oche(五體) and the nine body orifice. Otherwise the main function of the Six-Bu(六府) is to receive food, absorb the usable portions, and transmit and excrete waste. Therefore they can cause such problems as abdominal pain, distention, difficulty in urination, and constipation. The spleen is responsible for sending Grain-Ki(穀氣) so that is closely connected with the six-Bu. The Gall bladder takes care of control of giving out spirit. That's why it presents many symptoms related to the spirit that is ruled by the Five-Jang. Patterns of disharmony of external bodily form is influenced by the state of Meridians. Bodily forms get divided into many parts by the function of six-meridians(六經) to which they belong. Six-meridians have their own function related to excretion, related to excretion, retention, and balance(開闔樞). If local bodily forms get affected by pernicious influences, the Meridians to which they are attached will lose harmony and cannot fulfil their own functions. Because the meridian system unifies all parts of the body, the whole body will be under the influence of the affection although local parts of the bodily forms get affected. Therefore the symptoms of disharmony should be considered in a synthetic view. There are however, also cases which should be focused on the very meridian channels affected. Disorder within a Meridian generates derangement in the pathway make it not to benefit the muscles and skin belong to it. Because the meridians connect the interior organs with the exterior bodily form, they are influenced by each other.

As the foods and household manufacturing technology is developed, the packaging method of products is being changed from single to multi materials and layers. This study were focused on EPR carton packaging, economic and environmental expected effects were predicted by the improvements of packaging materials and structures to reduce effective packaging waste. Especially expected effects were predicted when improving the structure and material of aluminum laminated material was difficult to recycle. Thus, it was assumed the aseptic carton packaging laminated aluminum were replaced with silica laminated films. In conclusion, analysis of economic expected effects were undervalued in this study because of the limitation of assumptions, though this study has significance about a new approach by calculating the data different from the past that the conventional methods like predictive value of government's guidelines or goals.

In this paper, an adaptive range aggregation spatial index method is proposed for spatial range query in ubiquitous sensor networks. As the ubiquitous sensor networks are the new information-oriented paradigm, many energy efficient spatial range query methods in ubiquitous sensor networks environment are studied vigorously. In sensor networks, users can monitor environment scalar data such as temperature and humidity during user defined time and spatial ranges. In order to execute spatial range query efficiently, rectangle based index methods are proposed, such as SPIX. But they define the return path as the opposite of its query transmit path. However, the sensor nodes in queried ranges are closed to each other, they can't aggregate the sensed value in a queried range because their query transmission paths are different. As a result, the previous methods waste energy unnecessarily to aggregate sensing data out of the queried range. In this paper, an adaptive aggregation index method is proposed that can aggregate values in a user defined range adaptively by using its neighbor information. It is shown that sensor power is saved efficiently by using the proposed method over the performance evaluation.

Various concepts and practices of public deliberation have been exercised over the last three decades in western countries for science and technology (ST) governance. There has been a general social consensus for the need of such new governance notwithstanding, ends and means to achieve it varied. Among various rationales, while normative and substantive perspectives are explicitly claimed in public as reasons for public engagement in ST policy making, instrumental perspectives tend to be implicitly arranged by interested parties and still affecting policy significantly. This paper therefore, examines the implications of such instrumental perspectives in public engaged ST governance. To do so, this paper analyses the discourses and practices of public deliberation for ST governance in the UK from the late 1990's until the mid 2000's. It examines the proposals made by various policy institutions and two real public deliberations- the GM Dialogue for commercialization of genetically modified crops and the Committee on Radioactive Waste Management(CoRWM)'s programme. This study finds that policy institutions tried to employ public deliberation as strategic instrument for their policy interest, which contrasted with their outwardly claimed rationales of democratic policy making and better quality in decision for ST governance.

The purpose of this paper was to identify the effects of elimination of entrance fee (EEF) affecting visitor's satisfaction (VS) and management sectors such as natural resources (NRs), park facilities, transportation, visitor service, visitor atmosphere (VA) in national parks (NPs). This research had obtained data through a questionnaire, which surveyed 336 visitors at Gayasan NP in 2006. The data were analyzed the data using descriptive statistical methods, Pearson's correlation analysis, and multiple linear regression method. It was found that 1) About EEF, 72.6% of respondents agreed. 2) As entrance fee was abolished, respondents predicted that degree of VA such as crowding, waste throwing, disorder etc. grew worse most. On the other hands, respondents predicted number and quality of commercial lodging facilities, festival, and local products would improved. 3) Respondents predicted that degree of VS would worse. 4) in multiple regression analysis, the relative contribution of the VA on VS have been determined to have respectively 1.84 times more important than that of the change degree of NRs. The results suggested that the management of VA in NP was the most important factor to prevent decline of VS. This paper would be helpful to establish national park management policy after EEF.

This paper is to reclassify systematically the functions of urban river: that is, water supply, land management, transportation and energy source as social and economic function; formation of geomorphic surface, water-side landscape, community constitution and boundary and separation between regions as spatial function; and drainage of waste water, purification, habitation, and weather regulation as ecological function. On the basis of this reclassification, it can be argued that the socio-economic functions (eg. water supply) of the river among the functions of the river have been strongly mobilized in the process of modernization, while the spatial function and ecological function of urban river have been ignored. The Kumho river which flows through Daegu and the adjacent area has made a great contribution to the modem development process of the river basin area, but as a result of a selective development of a specific function of the river, that is the social and economic function, it now suffers from the lack of instream flow and is deprived of its original functions with the water pollution and degradation. Moreover the Daegu region seems no longer possible to develop on the dependence of the river. In order to overcome this kind of social and environmental crisis, this paper is to suggest both some principles and main evaluating indicators to restore the original and comprehensive functions of the river, and important measures to make the co-evolution of the city and the river possible.

A new online routing algerian is proposed in this paper, which use the interference-prediction to solve the network congestion originated from extension of Internet scope and increasing amount of traffic. The end-to-end QoS has to be guaranteed in order to satisfy service level agreements (SLAs) in the integrated networks of next generation. For this purpose, bandwidth is allocated dynamically and effectively, moreover the path selection algorithm is required while considering the network performance. The proposed algorithm predicts the level of how much the amount of current demand interferes the future potential traffic, and then minimizes it. The proposed algorithm considers the bandwidth on demand, link state, and the information about ingress-egress pairs to maximize the network performance and to prevent the waste of the limited resources. In addition, the interference-prediction supports the bandwidth guarantee in dynamic network to accept more requests. In the result, the proposed algorithm performs the effective admission control and QoS routing. In this paper, we analyze the required conditions of routing algorithms, the aspect of recent research, and the representative algorithms to propose the optimized path selection algorithm adequate to Internet franc engineering. Based on these results, we analyze the problems of existing algorithms and propose our algorithm. The simulation shows improved performance by comparing with other algorithms and analyzing them.

A sunday system with a horizontal bin-type composter was constructed and operated to evaluate its composting performance for four days for each test in October, 1992. A sundry system is one of popular systems for composting livestock manure, of which main benefit is to utilize unlimited, clean, and free solar radiation. A rectangular concrete bin(composter) with dimension of 300cm(length) X90cm(width) X60cm(height) was bedded alternatively with four lanes of aeration pipes and heating pipes, and was insulated at three walls with 50mm styrofoam. Each aeration pipe of a diameter of 25mm had 4mm perforated holes at every 15cm longitudinally, and supplied air of about 2m$^3$/min to the composter to maintain aerobic condition . A stirrer rotating at 1 rpm made one round trip every 20 minutes on the conveying chain along the the length of the composter. Five tests (Test 1~Test 5) were implemented to evaluate the composting effectiveness of a sundry system with a horizontal bin-type composter. Treatments of two levels of the mixture ratio of swine manure and paper sludge cakes(manure : paper sludge cakes= 1 : 4 and 1 : 2) and two levels of the water content(W/C ; 70% and 50%) were made to test the significance of the physicochemical properties for decomposition of the mixture materials. Temperature, C/N ratio, water content, microbial activity of the composting materials were taken measurements to evaluate its performance with the lapse of composting time for tests. A small-scale sundry system with a bin-type composter did not appear to be an appropriate system for composting livestock manure. Since heat generation by the composting materials could not overcome heat loss due to areation in a small-scale composter, a proper thermal enviroment could not be maintained to propagate massively thermopilic microorganism relatively in a short period of time. Different from the result of Chol et al.(1992) 6), a temperature variation of the composting materials did not show the peak clearly and C/N ratio didn't lower with time as expected. Mesophilic microoragnism seemed to play an important role for decomposition of the mixture materials. A sundry system with a bin-type composter may be good for a large-scale livestock farm household which may produce enough animal manure. Therefore a decision should be made very carefully to choose a system for composting livestock waste.

In this paper, we present an application layer protocol to support secure wireless Internet services, called Application Layer Security(ALS). The drawbacks of the two traditional approaches to secure wireless applications motivated the development of ALS. One is that in the conventional application-specific security protocol such as Secure HyperText Transfer Protocol(S-HTTP), security mechanism is included in the application itself. This gives a disadvantage that the security services are available only to that particular application. The other is that a separate protocol layer is inserted between the application and transport layers, as in the Secure Sockets Layer(SSL)/Transport Layer Security(TLS). In this case, all channel data are encrypted regardless of the specific application's requirements, resulting in much waste of network resources. To overcome these problems, ALS is proposed to be implemented on top of HTTP so that it is independent of the various transport layer protocols, and provides a common security interface with security applications so that it greatly improves the portability of security applications. In addition, since ALS takes advantages of well-known TLS mechanism, it eliminates the danger of malicious attack and provides applications with various security services such as authentication, confidentiality integrity and digital signature, and partial encryption. We conclude this paper with an example of applying ALS to the solution of end-to-end security in a present commercial wireless protocol stack, Wireless Application Protocol.
