The purpose of this study is to provide basic data for the development of the anger provoking situation scale using the mixed research method. For this purpose, three research methods were used: content analysis of domestic and international anger-inducing situation scale, NAS-PI factor and reliability analysis of youth anger-provoking scale, and FGI with youth expert. In the results of NAS-PI, there were four categories of 'unrespectful treatment', 'unfairness', 'annoying traits of others', and 'irritation' except 'frustration' among five categories. The results of the FGI consisted of seven categories: 'rejection', 'physical and verbal violence', 'ignorance', 'frustration', 'control and restraint', 'rumination', and 'interpersonal relationship'. As a result of integrating these contents, it is finally possible to reconstruction in to seven categories such as 'unfairness', 'injustice', 'ignorance', 'control and restraint', 'ignorance', 'frustration' 'interpersonal relationship'. The meaning of this study is to provide the basic data for the development of the anger provoking situation scale for domestic adolescents by integrating the contents analysis and quantitative and qualitative researches of domestic and international anger provoking situation scale. The results of this study are as follows. First, it is necessary to study the anger provoking situations reflecting sociocultural context, and to develop the reliability and validity of the anger provoking situation scale.

비닐하우스의 골조를 구성하는 파이프는 부식을 방지할 목적으로 아연도강관을 사용한다. 그러나 시간이 지남에 따라 아연도금량 감소와 여러 외부 환경인자 등에 의하여 부식이나 침식이 진행되어, 외관상 녹이 생기고 강도와 연신율 등이 감소하게 된다. 이는 비닐하우스 전체의 내구성을 저하시키는 요인으로 작용하게 되는데, 이를 평가하기 위한 방법이나 기준은 미비한 실정이다. 이에 본 연구에서는 농업시설의 내구성을 평가하기 위한 방법의 하나로 각기 다른 경과년수를 갖는 비닐하우스로부터 채취한 서까래 파이프의 인장 시험을 실시하였다. 인장 시험에 사용된 서까래 파이프는 (구)시설원예시험장에 설치되어 있는 비닐하우스에서 경과년별로 채취하였으며, 지중매설부와 지상노출부로 구분하여 시편을 제작하였다. 인장 실험 결과 서까래 파이프의 경과년이 오래될수록 시편의 인장 강도는 작아지는 경향을 보이고 있으나, 파단연신율은 경과년과 연관성을 찾아보기 어려운 것으로 나타났다. 그리고 동일한 경과년을 갖는 서까래 파이프 시편에서 지중매설부의 인장 강도와 파단연신율이 지상노출부에 비해 대체로 작게 측정되었으며, 경과년이 증가할수록 인장 강도의 감소폭이 커지는 경향을 보이는 것으로 나타났다.

As the dependency to network system and demands of efficient storage systems rapidly grows in every networking filed, the current trends initiated by explosive networked data grow due to the wide-spread of internet multimedia data and internet requires a paradigm shift from computing-centric to data-centric in storagesystems. Furthermore, the new environment of file systems such as NAS(Network Attached Storage) and SAN(Storage Area Network) is adopted to the existing storage paradigm for Providing high availability and efficient data access. We describe the design issues and system components of SANiqueTM, which is the cluster file system based on SAN environment. SANiqueTM has the capability of transferring the user data from the network-attached SAN disk to client applications directly We, especially, present the protocol and functionality of the global buffer manager in our cluster file system.

In this paper, the authors propose a multi-transmission mechanism of heterogeneous network environment which is applicable to the SMART screen services over wire and wireless convergence network. This paper presents study results including a SMART screen handover algorithm among multiple collaborative devices under wire and wireless convergence and heterogeneous network environment, and a service operation and management system and a NAS system providing SMART services of AV streaming and contents files. These validate implementation feasibility of a call processing engine for seamless SMART screen collaborative services, AV streaming services and SMART screen collaborative services supporting mobility management and multiple users/multiple streams.

The rapid growth of high speed multimedia services demands the large capacity of the server's storage that maintains the multimedia contents. Among the server's devices, the low I/O speed and physical or logical failure of storage device decrease the total performance of system. The continuous increase of multimedia contents require the flexibility of storage capacity. In order to solve the these problems, we propose the uses of software RAID and LVM techniques that provide the performance improvement and reliability of storage device and the flexibility of storage device respectively. In the LINUX 2.4 kernel, we implemented the reliable and flexible storage device and evaluated the performance of it.

High temperature sodium/sulfur battery(Na/S battery) has good electrochemical properties, but, the battery has some problems such as explosion and corrosion at al. because of using the liquid electrodes at high temperature and production of high corrosion. Room temperature sodium/sulfur batteries (NAS batteries) is developed to resolve of the battery problem. To recently, room temperature sodium/sulfur batteries has higher discharge capacity than its of lithium ion battery, however, cycle life of the battery is shorter. Because, the sulfur electrode and electrolyte have some problem such as polysulfide resolution in electrolyte and reaction of anode material and polysulfide. Cycle life of the battery is improved by decrease of polysulfide resolution in electrolyte and block of reaction between anode material and polysulfide. If room temperature sodium/sulfur batteries (NAS batteries) with low cost and high capacity improves cycle life, the batteries will be commercialized batteries for electric storage, electric vehicle, and mobile electric items.

The random V(D)J recombination process ensures the diversity of the primary immunoglobulin (Ig) repertoire. In two thirds of cases, imprecise recombination between variable (V), diversity (D), and joining (J) segments induces a frameshift in the open reading frame that leads to the appearance of premature termination codons (PTCs). Thus, many B lineage cells harbour biallelic V(D)J-rearrangements of Ig heavy or light chain genes, with a productively-recombined allele encoding the functional Ig chain and a nonproductive allele potentially encoding truncated Ig polypeptides. Since the pattern of Ig gene expression is mostly biallelic, transcription initiated from nonproductive Ig alleles generates considerable amounts of primary transcripts with out-of-frame V(D)J junctions. How RNA surveillance pathways cooperate to control the noise from nonproductive Ig genes will be discussed in this review, focusing on the benefits of nonsense- mediated mRNA decay (NMD) activation during B-cell development and detrimental effects of nonsense-associated altered splicing (NAS) in terminally differentiated plasma cells.
