비주얼 노블은 여러 멀티미디어적 요소를 결합한 연출과 게임성이 돋보이는 수행성을 살리고 하이퍼텍스트 구조를 살린 서사를 도입하면서 플레이어인 독자에게 텍스트 읽기의 즐거움을 다양한 방면으로 전하는 데에 그 목적이 있다. 본 분석은 게임성과 서사성을 함께 추구하려고 한 비주얼 노블 컨텐츠가 멀티 시나리오를 구축하는데 있어 어떤 경향으로 제작해 왔는지 수행성이 서사에 담긴 시나리오와, 캐릭터별로 멀티 시타리오를 구축한 두 가지 유형으로 나누어 분석한다. 비주얼 노블은 서사와 게임성을 추구하는 컨텐츠로, 입체적 서사구성에 방점을 두고 있으며 이러한 멀티 시나리오의 구조를 알아가는 것은 앞으로의 컨텐츠 창작에 있어 실제적인 도움이 될 것이라 기대한다.

A methodology to assess seismic fragility of a nuclear power plant (NPP) using a conditional mean spectrum is proposed as an alternative to using a uniform hazard response spectrum. Rather than the single-scenario conditional mean spectrum, which is the conventional conditional mean spectrum based on a single scenario, a multi-scenario conditional mean spectrum is proposed for the case in which no single scenario is dominant. The multi-scenario conditional mean spectrum is defined as the weighted average of different conditional mean spectra, each one of which corresponds to an individual scenario. The weighting factors for scenarios are obtained from a deaggregation of seismic hazards. As a validation example, a seismic fragility assessment of an NPP containment structure is performed using a uniform hazard response spectrum and different single-scenario conditional mean spectra and multi-scenario conditional mean spectra. In the example, the number of scenarios primarily influences the median capacity of the evaluated structure. Meanwhile, the control frequency, a key parameter of a conditional mean spectrum, plays an important role in reducing logarithmic standard deviation of the corresponding fragility curves and corresponding high confidence of low probability of failure (HCLPF) capacity.

게임에서 시나리오는 매우 중요한 요소이다. 그러나 아직까지 게임 시나리오 제작을 위한 범용적인 툴은 개발되어 있지 않다. 이를 해결하기 위해서 게임 시나리오와 일반적인 시나리오의 차이점을 알아보고 시나리오 UCC를 분석하여 게임 시나리오에 적합한 구조를 설계하였다. 또한 OSMU의 적용을 쉽게 하기 위해 XML로 게임 시나리오 구조를 정의 하였다. 정의한 시나리오 구조의 활용 가능성을 확인하기 위하여 시나리오 편집기를 만들어 게임 시나리오를 작성한 후 시나리오 기반 게임 "필온라인"에 적용하였다.

The importance of performing Level 3 probabilistic safety assessments (PSA) along with a general interest in assessing multi-unit risk has been sharply increasing after the Fukushima Daiichi nuclear power plant (NPP) accident. However, relatively few studies on multi-unit Level 3 PSA have been performed to date, reflecting limited scenarios of multi-unit accidents with higher priority. The major difficulty to carry out a multi-unit Level 3 PSA lies in the exponentially increasing number of multi-unit accident combinations, as different source terms can be released from each NPP unit; indeed, building consequence models for the astronomical number of accident scenarios is simply impractical. In this study, a new approach has been developed that employs the look-up table method to cover every multi-unit accident scenario. Consequence results for each scenario can be found on the table, established with a practical amount of effort, and can be matched to the frequency of the scenario. Preliminary application to a six-unit NPP site was carried out, where it was found that the difference between full-coverage and cut-off cases could be considerably high and therefore influence the total risk. Additional studies should be performed to fine tune the details and overcome the limitations of the approach.

BIM 과 ICT 기술이 도입됨에 따라 '클라우드 기반 협업 설계 지원 시스템'에 관한 연구가 활발히 진행되고 있으며 이를 지원하기 위한 새로운 사용자 인터페이스가 필요하게 되었다. 사용자 인터페이스를 개발할 때 실제 사용 시나리오를 기반으로 사용 상황을 예상하고 사용자의 요구사항을 반영할 수 있는 시나리오 기반 디자인 기법을 선택하였다. 하지만 기존의 시나리오 기반 디자인 기법은 귀납적인 방식이기 때문에 이를 통해 사용 시나리오를 작성할 경우에는 모든 사용자의 사용 상황에 대한 대응이 현실적으로 어렵다. 이러한 이유로 귀납적 방식이 아닌 체계적으로 시나리오를 작성하고 수정할 수 있는 새로운 시나리오 작성 기법이 필요하다. 본 연구에서는 기존의 방식을 보완한 다중 시나리오 기반의 디자인 기법을 제안하였고 이를 '클라우드 BIM 기반 협업 설계 지원 시스템'의 사용자 인터페이스 개발 과정에 적용하여 사용성을 검증하였다.

This study would present a risk analysis method to evaluate stable tap water supply in a multi-regional water supply system and propose a measure for the evaluation of the effect of the conjunctive operation of the multi-regional water supply system using this. Judging from the vulnerability for the crisis response of the entire N. multi-regional water supply system, as compared to the result of Scenario 1 in which no conjunctive pipes were operated, it was found that in Scenario 2, in which conjunctive pipes were partially operated, the vulnerability of crisis response decreased by about 30.6%, and as compared to Scenario 3, the vulnerability of crisis response decreased by 86.2%. In setting a plan for stable tap water supply in N multi-regional water supply system, using the estimated value and the method for the evaluation of the vulnerability of crisis response by pipe, by interval and by line, it is judged that this can be utilized as a basis for the judgment of the evaluation of the operation or the additional installation of conjunctive pipes.

The positive and negative opinion to cargo demand of Incheon's SAMT in the near future remains cloudy. Considering port and shipping environmental changes and the logistics situation of China which explains the lack of facilities in Chinese airports, the creating of SAMT cargoes of the Incheon region could catches a favorable opportunity to be a logistics hub in the North-East Asia. On the other hand, as open-sky policy and direct-call service has been carried out between China and N.A.(North America), Incheon could cause a loss of competitiveness in SAMT because the enhancement in the aspect of the connectivity of Chinese airlines and shipping lines makes customer sent to last destination their cargoes whenever they want. In the same context, this paper analyses on conditions of domestic and international SAMT and proposes in this uncertainty future forecasting of SAMT of Incheon by scenario planning according to changes in integrated SAMT, measuring the likelihood of final scenario. This study shows the Sea & Air multi-transport volume will have either slight increase or decrease from the current condition. Consequently, RFS expansion and system & service improvement through strong ties with major cities in China will be required in a short run aspect. Nonetheless, we also need to take domestic & international transportation environment into account in the long run.

The multi-scenario topology of multi-channel hybrid ubiquitous sensor networks (USNs) is studied and a novel link auto-diversity cross-layer cooperative scheduling scheme is proposed in this paper. The proposed scheme integrates the attributes of the new performance evaluation link auto-diversity air-time metric and the topology space in the given multi-scenario. The proposed scheme is compared with other schemes, and its superiority is demonstrated through simulations. The simulation results show that relative energy consumption, link reception probability, and end-to-end blocking probability are improved. The addressing ratio of success with unchanged parameters and external information can be increased. The network can tolerate more hops to support reliable transportation when the proposed scheme is implemented. Moreover, the scheme can make the network stable. Therefore, the proposed scheme can enhance the average rate performance of the hybrid USN and stabilize the outage probability.

Since there is currently no commercial protocol simulator for CDMA mobile communication system, we need to develop a General-Purposed Protocol Test Simulator (G-PTS). This paper is concerned with the design and implementation of this G-PTS contains the multi-scenario generating functions, multi-tasking kernel and multiple interface functions. Thus it can be utilized in the test category using multiple base-stations such as soft-handoff, 3-way handoff and mulit-party call features. G-PTS is verified using the model of CDMA soft handoff scenario and the result shows its reliable operations.

Since the Fukushima Daiichi accident, there has been an emphasis on the risk resulting from multi-unit accidents. Human reliability analysis (HRA) is one of the important issues in multi-unit probabilistic safety assessment (MUPSA). Hence, there is a need to properly identify all the human and organizational factors relevant to a multi-unit incident scenario in a nuclear power plant (NPP). This study identifies and categorizes the human and organizational factors relevant to a multi-unit incident scenario of NPPs based on a review of relevant literature. These factors are then analyzed to ascertain all possible unit-to-unit interactions that need to be considered in the multi-unit HRA and the pattern of interactions. The human and organizational factors are classified into five categories: organization, work device, task, performance shaping factors, and environmental factors. The identification and classification of these factors will significantly contribute to the development of adequate strategies and guidelines for managing multi-unit accidents. This study is a necessary initial step in developing an effective HRA method for multiple NPP units in a site.
