The China has opened the distribution market completely since it joined the World Trade Organization on Dec 11 2001. The notable features of Chinese distribution market are the transition from the consumers' monolithic demand to diversification for the luxury goods, well-being products. The regional characteristics of consumers are smart, conservative, optimistic and advanced. and the open door policy has prompted the capitalistic economy gradually. We analyzed the Chinese distribution markets and came up with the following strategies. First, we recommend the setting of the key regional market not covering the whole chinese markets. then we can extend the main market step by step. Second, we need to cooperate and advance with the Korean distribution companies which entered into markets already. Third, we need to acquire the competitive and stable distribution channel in China. Fourth, we need to implement the localization strategy in terms of human resources and procurement. Fifth, the consignment management can be another strategy. I hope this research can be a little help to those who wish to expand to the Chinese markets.

After the Kyoto Protocol has been ratitied in Feb. 16 2005, the developed countries which is involved in Annex-1 have tried to mitigate GHG to the reduction objective. To accomplish this objective, EU developed EU-ETS, CDM project, and so on. Korea has faced pressure to be a member of Annex-1, because Korea and Mexico are only non-Annex-1 countries in the OECD nations. This study is intended to examine unfolding transition on negotiations of Conference of Parties(COP), the Kyoto Mechanism referred as a cost-effective tool to meet a targeted level of greenhouse gas decrease, and trends in responses of developed countries to the Kyoto Protocol, and finally suggests legal and politic counterplans responding to the United Nations Framework Convention on Climate Change(hereafter, UNFCCC).

We discuss scheduling analysis for a discrete event system with time windows of which firing or holding time delays are subject to random variation within some finite range. To do this, we propose a modified p-lime Petri net, named p+-time Petri net. We develop a condition for which a synchronized transition does not have a dead token, that is, the firing epochs do not violate the time window constraints. We propose a method of computing the feasible range of the token sojourn time at each place based on a time difference graph. We also discuss an application for analyzing wafer residency times within the process chambers for a dual-armed cluster tool for chemical vapor deposition.

Recently, Internet Telephony has become increasingly popular in telecommunication industry. However, previous research on Internet Telephony has focused on analyzing specific Internet Telephonysolutions, identifyingthe Internet Telephony movement itself. The research on prediction models about Internet Telephony adoption has been minimal. The main propose of this study is to develop models for predicting transition intention from using traditional telephones to using Internet Telephony. To do so, this study uses data mining methods to analyze demands in the IT communications market and to provide management strategies for Internet telephony providers. Especially this study uses discriminant analysis, logistic regression, classification tree, and neural nets to develop those prediction models toward Internet Telephony adoption. The models are compared with each other and a superior model is chosen.

We in this paper propose a prognosis graph, analyzing prognoses of each pattern described in the Korean medicine literatures. This graph is represented as the integrated graphs about knowledge of patterns and their transitions in the prognoses, where a node becomes a pattern name and a edge becomes a transition between patterns, along with a condition with respect to cause or mechanism of the pattern. The knowledge of prognoses which a pattern is transit into another pattern can be identified at a glance by using this model. We also construct a upper-level prognosis graph, excluding five viscera and six entrails from the model. This upper-level prognosis graph contains the conceptual knowledge than clinical one so that it may be helpful to students and researchers in the Korean medicine fields.

The transition from fossil to renewable energy is inevitable due to fossil depletion. So, Renewable energy is very important for energy security and economic growth although it's R&D is long-term and high risky project. We propose new valuation method which combined system dynamics and compound real option method for long-term and high risk projects such as renewable energy. This method can show dynamic valuation results for the complex causal interaction and be easy for Monte-Carlo simulation to estimate volatility. And it can reflect the value of flexible decision for uncertainty. We applied the empirical analysis for Korea's photovoltaic industry by using this method. As results by empirical analysis, photovoltaic's R&D has high valuation using this method compared by traditional valuation methods such as DCF.

Application software is delivered to customers as a form of service at cloud environment. A cloud service provider is a marketplace between supply side (application providers) and demand side (customers). Cloud service providers have to validate applications to be included in their service portfolio. Not only performance, security, networking, compliances should be checked but also business contract, authentication should be provided. Organization customers are more sensitive to these validation criteria and process. We study the Internet2 NET+, which is a successful cloud marketplace of applications for research and education organizations. This case study shows us three things : (i) a cloud marketplace's application management process : selection, validation, transition to service, customization of applications (ii) what a cloud marketplace has for its infrastructure like authentication, security, access control etc. (iii) what a cloud marketplace has as its governance structure. This case study will provide informative analysis of Internet2 NET, a profit-making vertical and buyer's marketplace (education industry). And we will get some strategic implications for planning and implementing cloud marketplaces.

The Slaughterhouse is the place where animals are butchered for food. This study is to investigate the establishment and transition of slaughterhouse operated in Busanbu(釜山府) as public facilities during Japanese Colonial Period. It was established in relation to the application of hygienics which the idea of modern natural science and technology produced at that time. The establishment of slaughterhouse was based on the leading knowledge of public health. It also provided important revenues for the local government and became one of the techniques of Japanese Colonial Rule. The slaughterhouse was turned into the public management in 1921 and had to be shifted twice. Eventually, it had an effect on the culture of food greatly.

In this study, S food manufacturing business located in Chungbuk was selected as the subject, and the transition in insulation resistance in major electrical equipment used in this food manufacturing business was analyzed for 4 years (2018-2021). It was confirmed that the insulation resistance decreased over time for all 18 electrical facilities. Insulation resistance changed due to environmental influences such as load characteristics and ambient temperature. Particularly in the case of the food manufacturing industry, it was confirmed that the decrease started after 2 years, although it varied depending on equipment and environmental influences. Furthermore, it was confirmed that management through predicting the management cycle of electrical equipment is possible by deriving a regression equation through regression analysis of insulation resistance measurement values.

본 논문에서는 역추적 비터비 디코더의 순서적 역방향 상태천이 제어에 의한 새로운 생존 메모리 제어와 복호기법을 제안한다. 비터비 알고리즘은 채널오류의 검출과 정정을 위한 부호기의 상태를 추정해서 복호하는 최우추정 복호기법이다. 이 알고리즘은 심볼간 간섭의 제거나 채널등화 등 디지털 통신의 광범위한 분야에 응용되고 있다. 반복연산의 과정을 내포하고 있는 비터비 디코더에서 처리속도의 향상과 함께 VLSI 칩 설계시 점유면적의 삭감을 통한 칩 사이즈의 축소 및 소비전력의 저감 등을 달성하기 위해서는 새로운 구조의 ACS 및 생존 메모리 제어에 관한 연구가 요구되고 있다. 이를 해결하기 위한 하나의 방안으로, 본 논문에서는 역추적 기법에 의한 복호과정에서 역방향 상태천이의 연속적인 제어에 의한 자동 복호 알고리즘을 제안한다. 제안방식은 기존의 방법에 비해 전체 메모리 사용량이 적을 뿐만 아니라 구조가 간단하다. 또한, 메모리 억세스 제어를 위한 주변 회로구성이 필요 없고, 메모리 억세스를 위한 대역폭을 줄일 수 있어 칩 설계시 area-efficiency가 높고 소비전력이 적어지는 특성이 있다 시스톨릭 어레이 구조 형태를 갖는 병렬처리 구성과, 채널잡음을 포함한 수신 데이터로부터의 복호와 구체적인 응용 시스템에 적용한 결과를 제시한다.
