Consider a stuffing process where sausage-casings are filled with sausage-kneading. One of the most important factors in the stuffing process is weights of stuffed sausages. Sausages weighting above the specified limit are sold in a regular market price for a fixed price, and underfilled sausages are reworked at the expense of reprocessing cost. In this paper, the sausage stuffing process is inspected for improving productivity and quality levels. Several statistical process control tools are suggested by using real data obtained from a Korean Vienna sausage company.

The challenges China is facing in energy security are briefly discussed. Then, the development of nuclear power in China in the first half of 21 st century is envisioned, and it is expected that Generation-3 PWR nuclear power plants (NPPs) would be the leading units of nuclear power in the coming $30\~40$ years. As part of the nuclear power program, the R&D work on nuclear fuel cycle is generally proposed.

Two conceptual flowsheets were developed for recycling used nuclear fuel. One flowsheet was developed for recycling used oxide nuclear fuel from light water reactors while the other was developed for recycling used metal fuel from fast spectrum reactors. Both flowsheets were developed from a set of design principles including efficient actinide recovery, nonproliferation, waste minimization and commercial viability. Process chemistry is discussed for each unit operation in the flowsheet.

The denuclearization of North Korea was unpredictable and resulted in radical changes. Despite the skepticism and disappointment surrounding denuclearization, it is important for certain verification technologies to establish what is technically possible or practically impossible, and how reliable these technical means are. This article presents the technical hurdles in nuclear verification by systematically categorizing them into issues of correctness and completeness. Moreover, it addresses the safety and security risks during the denuclearization process, including the radiological impact on humans, environmental effects, and the illegal transfer of material, information, and technologies.

본고는 최근 미국의 911 사태이후 정신의학 분야에서 관심사로 떠오르고 있는 재해정신의학 (Disaster Psychiatry)에대한 고찰을 통해 국내에서 대형재해 발생시 소아청소년 정신과 의사로서의 일정역할을 모색코자하는 목적의 일환이다. 우선 성인과 달리 소아청소년 재해환자에대한 치료를 다룰 때 어떤점을 고려하여야하는가에대한 연령 발달적 특이성를 살펴보고, 예방프로그램과 소아청소년 특유의 치료법은 무엇인가에대해 살펴보았다. 이를 요약하면 1) 소아는 타인에게 의존해야하는 존재로 부모 혹은 가족의 아이에대한 태도와 지지가 예후 결정에 가장 중요한 요소임으로 가족치료 부모교육의 중요성이 강조되며, 2) 개인치료에서는 인지행동적 요소가 여러 연구 문헌을 통해 가장 효과가 입증된 치료기법이고, 3) 놀이면담치료, fellow victim으로 구성된 집단치료 역시 효과적이며, 4) 1회성 재해를 당한 공포환자의 경우 특수기법인 EMDR(Eye Movement Desensitization and Reprocessing)의 시도가 추천되고, 5) 약물치료의 경우 2차적 혹은 보조치료수단이 되는데 성인에서 시도되는 다양한 약물의 적용이 가능하지만 부작용에대한 주의가 필요하다.

Objective : Disaster causes psychological distress to a large number of people in a short period of time, by both direct and indirect exposure to traumatic events embedded in various realms of disaster experience. Optimal, well-planned treatment interventions should follow from the early acute period to recovery phase, extending up to several months later. In this context, there is an increasing need for systemic review to gain comprehensive insights for disaster interventions. These need to be added to public policy, and for the prevention and treatment of disaster-related psychopathology. Here, we review the published studies on psychological interventions for disaster-related posttraumatic stress disorder. Methods : Specific psychological interventions regarded as effective treatments for have been selected for this review, such as CBT (Cognitive-Behavior Therapy), Exposure Therapy, EMDR (Eye Movement Desensitization & Reprocessing), SIT (Stress Inoculation Therapy) and Psychoeducation. In addition, natural disasters, industrial disasters, and accidents involving aircraft and ships were also categorized as disasters, along with war and combat trauma. Results : Cognitive behavior therapy and exposure therapy had the strongest research support for effectiveness, and could be considered as the first-choice treatment for disaster-related PTSD. The second line of treatment is EMDR, although this treatment modality has the advantage of reaching certain treatment improvements in fewer sessions. However, the effects of SIT and psychoeducation to the survivors of disasters, remains unclear at this point. Additionally, we propose the possibilities of using virtual reality component and imagery rescripting as modified forms of traditional cognitive behavior therapy and exposure therapy. Conclusion : Cognitive behavior therapy and exposure therapy, deemed effective treatments for various trauma, are considered to be effective for survivors from disasters. However, the efficacy of other interventions has not yet been examined methodologically in well-designed studies, such as randomized controlled trials. In particular, future empirical studies are needed, since it is difficult to conclude that psychological interventions have similar effects on different types of disasters.

본 논문에서는 국가자격종합관리시스템 구축 및 운영의 효율성을 향상시키기 위하여 외부위탁 관리시스템과 연계한 실시간 자료공유 시스템을 설계하고 개발하였다. 현재까지 대부분의 국가자격 종합관리시스템은 IT 전문기업에 개발, 구현, 운영에 대한 전반적인 사항을 위탁으로 수행한 후, 처리 결과에 대한 정보를 인수받아 업무를 처리하였다. 이러한 처리방식은 전체적인 정보에 대한 재처리, 기능추가, 시스템 안정성 등에 많은 문제점을 가지고 있다. 제안된 실시간 자료공유 시스템의 성능평가를 위하여 기본적 시뮬레이션으로 파일럿시스템에서 제안 기술을 적용하여 검증 한 후 대한상공회의소 실시간 국가기술자격 시험에 적용한 결과 안정성이 입증되어 지방상공회의소까지 지속적으로 확대 적용할 계획이다. 국가자격종합관리 실시간 자료공유 시스템은 정보재처리와 부가기능 추가시 발생되는 개발기간에 대한 문제를 근본적으로 해결하였으며 안정적 시스템운영 상태와 최대 효율성을 보여주었다. 특히 국가자격시스템 내부관리자와 운영자에 대한 관리체계와 편리성에서 최상의 평가를 도출하였다.

This technical paper deals the practical transformation algorithms between several lunar reference frames which will be used for Korea pathfinder lunar orbiter (KPLO) flight operation. Despite of various lunar reference frame definitions already exist, use of a common transformation algorithm while establishing lunar reference frame is very important for all members related to KPLO mission. This is because use of slight different parameters during frame transformation may result significant misleading while reprocessing data based on KPLO flight dynamics. Therefore, details of practical transformation algorithms for the KPLO mission specific lunar reference frames is presented with step by step implementation procedures. Examples of transformation results are also presented to support KPLO flight dynamics data user community which is expected to give practical guidelines while post processing the data as their needs. With this technical paper, common understandings of reference frames that will be used throughout not only the KPLO flight operation but also science data reprocessing can be established. It is expected to eliminate, or at least minimize, unnecessary confusion among all of the KPLO mission members including: Korea Aerospace Research Institute (KARI), National Aeronautics and Space Administration (NASA) as well as other organizations participating in KPLO payload development and operation, or further lunar science community world-wide who are interested in KPLO science data post processing.

As the use of smart devices is being increased rapidly by the development of internet and IT technology, the contents production and utilization rate are showing higher increase, too. In addition, the type of contents also shows very diverse forms such as education, game, video, UCC, etc. In the meantime, the contents are reproduced in diverse forms by reprocessing the original contents, and they are being serviced through the contents service platform. Therefore, the platform to make the contents reprocessing easy and fast is needed. As the diverse contents distribution channels such as YouTube, SNS, App Service, etc, easier contents distribution platform is needed, and the development of the relevant area is expected. In addition, as the selective consumption of the contents having easy accessibility through diverse smart devices is distinguished, the demand for the platform and service that can identify the contents consumption propensity by individual is being increased. Therefore, in this study, to vitalize the online contents distribution, the contents reproduction and publishing platform, was designed and materialized, which can reproduce and distribute the contents based on the real-time contents editing technology in URL unit and the consumer propensity analysis technology using the data management-based broadcasting contents distribution metadata technology and the edited image contents streaming technology. In addition, in the results of comparing with other platforms through the experiment, the performance superiority of the suggested platform was verified. If the suggested platform is applied to the areas of education, broadcasting, press, etc, the multi-media contents can be reproduced and distributed easily, through which the vitalization of contents-related industry is expected.
