소프트웨어 프로덕트라인에서 가변성은 프로덕트라인의 멤버제품들을 차별화하는 특성으로, 가변성의 기술은 의미가 명확하고 선택이 용이하도록 가시화되어야 하며 관리하기 용이하여야 한다. 가변성 기술은 크게 개발 모델에 통합하는 방법과 개발 모델과는 독립적으로 기술하는 방법으로 나눌 수 있다. OVDL (Orthogonal Variability Description Language)은 독립적 가변성 기술 방법이면서 타 방법들의 가지는 의미의 모호성을 개선하기 위하여 제안된 가변성 표현 언어이다. 이 논문은 독립적 가변성 기술 방법의 기반을 제공한 OVM (Orthogonal Variability Model)으로 기술된 IWF (Inter-Working Function) 프로덕트라인의 가변성이 OVDL로 번역될 수 있는지 확인하는 방식으로 OVDL의 가변성 기술 역량을 검증한다.

This study examined the effects of closeness of peer relationships on intersubjectivity in young children's joint story making of wordless picture books. The joint story making activity of 32 five-year-old children was videotaped and transcribed, and the structure and negotiation types of interaction were examined by Goncu's (1993a) measure of intersubjectivity. Results showed (1) closeness of peer relationship was related to the structure of intersubjectivity children working with very close peers exhibited more turns. (2) Children working with very close peers used more extension and acceptance negotiation types, whereas the children working with non-close peers used more building-on of own ideas and irrelevant acts of negotiation.

In this paper we consider the multi-robot system that collects target objects spread in an unexplored environment. The robots cooperate each other to improve the capability and the efficiency. The robots attract or intimidate each other as behaviors of bacterial swarms or particles with electrical moments. The interactions would increase the working efficiency in some environments but it would decrease the efficiency in some other environments. Therefore, the system needs to adapt to the working environment by adjusting the strengths of the interactions. The strengths of the interactions are expressed as sets of gene codes that mean the weights of each kind of attracting or intimidating vectors. The proposed system adjusts the gene codes using evolutional strategy. The proposed approach has been validated by computer simulation. The results of this paper show that our inter-swarm interacting strategy and optimizing algorithm improves the working efficiency, adaptively to the characteristics of environments.

Promotion of the line no.2 in Seoul Metro was changing from the existing signaling facilities for ATS(Automatic Train Stop) vehicles to the up-to-date signaling facilities for ATO(Automatic Train Operation). But, in consequence of conducting a trial run after being equipped with the ATO signaling facilities, the matter related to mix-operation with the existing ATS signaling facilities appeared. The operation of the existing ATS signaling system in combination with the ATO signaling system has made improper working related to frequency recognition of the ATS On-board Computerized Equipment. This obstructs operation of a working ATS vehicle. That is, as barring operation of an ATS vehicle that should proceed, it may make the proceeding ATS vehicle stop suddenly and after all, it will cause safety concerns. In this paper, we designed a wayside track occupancy detector that previously prevents improper working related to frequency recognition of the ATS On-board Computerized Equipment by gripping classification and working processes of operating trains throughout transmission of local signaling information from the existing facilities, which does not need to change or replace the existing signaling facilities. Furthermore, we described general characteristics of the wayside track occupancy detector and modeled the IFC(InterFace Contrivance) device and the logical circuit recognizing signal information. Then, we made an application program of PLC(programmable Logic Computer) based on the stated model. We, in relation to data transfer method, used the frame in TCP/IP transfer mode as the standard, and we demonstrated that ATO transmission frequency is intercepted.

Aiming at studying the plastic hinge (PH) evolution regularities and failure mode of rocking wall moment frame (RWMF) structure in earthquakes, the whole-working history analysis of seismic performance state of RWMF structure based on co-operation performance and PH evolution was carried out. Building upon the theoretical analysis of the elastic internal forces and deformations of RWMF structures, nonlinear finite element analysis (FEA) methods were employed to perform both Pushover analysis and seismic response time history analysis under different seismic coefficients (δ). The relationships among PH occurrence ratios (R_ph), inter-story drifts and δ were established. Based on the plotted curve of the seismic performance states, evaluation limits for the R_ph and inter-story drifts were provided for different performance states of RWMF structures. The results indicate that the R_ph of RWMF structures exhibits a nonlinear evolution trend of "fast at first, then slow" with the increasing of δ. The general pattern is characterized by the initial development of beam hinges in the middle stories, followed by the development towards the top and bottom stories until the beam hinges are fully formed. Subsequently, the development of column hinges shifts from the bottom and top stories towards the middle stories of the structure, ultimately leading to the loss of seismic lateral capacity with a failure mode of partial beam yield, demonstrating a global yielding pattern. Moreover, the limits for the R_ph and inter-story drifts effectively evaluate the five different performance states of RWMF structures.

Purpose: This study was aimed to investigate the effect of an education program on inter-rater agreement of Neonatal/Infant Braden Q Scale for clinical nurses working at a neonatal intensive care unit (NICU). Methods: This was single-arm pre and post experimental study. The participants were 12 nurses and 128 hospitalized neonates at a NICU from December, 2012 to March, 2013. Twelve nurses were divided into four different groups; for two groups were assigned nurses with 3 to 5 years of clinical experiences, and for the others with less than 1 year of clinical experience. The interventions were given by one wound ostomy specialist and two NICU nurses with over 5 years of clinical experiences for 1 hour twice. The inter-rater agreement was measured by intraclass-correlation coefficient. Results: Overall inter-rater agreement was improved from .87(95% CI: .80~.92) at the pre-test to .94(.91~.96) at post-test. Each inter-rater agreement except moisture and nutrition was also improved. Conclusion: The developed education program on scoring for Neonatal/Infant Braden Q scale was effective to improve the inter-rater agreement among clinical nurses. We suggest to privide an education for NICU nurse before using the Neonatal/Infant Braden Q scale in clinical settings.

현재 남북관계는 그동안의 교착상태에서 벗어나 교류협력의 핵심적인 실무 협상단계를 진행하고 있으며 향후 남북한 당국간 회담은 더욱 증가될 것으로 예상된다. 이에 대한 체계적이고 효율적인 협상대책이 필요한 시점이다. 사회과학의 목적이 사회현상의 설명과 예측에 있다고 본다면 현 시점에서 1953년 7월 27일 정전협정이 체결된 이후 한국의 군사대표단으로 구성된 인원들이 북한 군부 대표들과 군사문제를 논의한 군사협상의 대표적인 남북국방장관회담, 남북장성급군사회담, 남북군사실무회담을 분석해보면 향후 협상에 대한 새로운 정보를 획득할 수 있는 사항이다. 본 연구는 김정일 시대 북한의 대남 군사협상행태에 대해 총체적 차원에서 분석, 평가하였다. 북한 김일성의 회고록 '세기와 더불어'에 제시된 항일유격대 시절 각종 협상을 분석하여 군사협상에 대한 "항일유격대식 협상모델"의 분석틀을 제시하여 김정일시대 군사협상의 행태가 협상모델의 틀속에서 진행되고 있음을 증명하고자 하였다. 증명 결과를 바탕으로 항일유격대식 협상모델의 특성을 활용하여 향후 예상되는 각종 남북회담, 특히 남북관계 개선과 한반도의 평화를 제고 시킬 수 있는 남북 군사회담에 대한 효율적인 대책과 방안을 제시하고자 한다. 이와 같은 결과를 근거로 2013년 김정은시대에 실시되었던 경제분야의 개성공단 실무협상에서도 항일유격대식 협상모델의 적용 여부를 분석해 보았다. 이것은 군사협상의 모델인 항일유격대식 협상모델이 일반협상에서도 적용할 수 있음을 증명하여 북한과의 제반 협상에 대비하고자 함이다. 즉 북한과의 각종 경제협상에 대비한 통상정보의 활용측면과 개성공단 실무협상 분석을 통하여 경제협력 실천방안을 찾아보고자 한다.

Phytochromes (with gene family members phyA, B, C, D, and E) are a wavelength-dependent light sensor or switch for gene regulation that underscore a number of photo responsive developmental and morphogenic processes in plants. Recently, phytochrome-like pigment proteins have also been discovered in prokaryotes, possibly functioning as an auto-phosphorylating/phosphate-relaying two-component signaling system (Yeh et al., 1997). Phytochromes are photochromically convertible between the light sensing Pr and regulatory active Pfr forms. Red light converts Pr to Pfr, the latter having a "switch-on" conformation. The Pfr form triggers signal transduction pathways to the downstream responses including the expression of photosynthetic and other growth-regulating genes. The components involved in and the molecular mechanisms of the light signal transduction pathways are largely unknown, although G-proteins, protein kinases, and secondary messengers such as $Ca^{2+}$ ions and cGMP are implicated. The 124-127 kDa phytochromes form homodimeric structures. The N-terminal half contains the tetrapyrrolic phytochromobilin for red/far-red light absorption. The C-terminal half includes both a dimerization motif and regulatory box where the red light signal perceived by the chromophore-domain is recognized and transduced to initiate the signal transduction cascade. A working model for the inter-domain signal communication within the phytochrome molecule is proposed in this Review.

Prostatic adenocarcinoma is the commonest solid malignancy seen in Omani elderly males 60-80 years of age. The Gleason grade is the most widely used grading system for prostatic carcinoma and is recommended by the World Health Organization. A peer review was carried out at the Pathology Department of Sultan Qaboos University Hospital (SQUH), Oman, to assess the quality of reporting at the center. The aim of this study was to determine inter-observer variation among 7 pathologists working at a tertiary care center in Oman. A total of 47 consecutive prostatic biopsies were interdependently reviewed by seven pathologists and the results obtained were compared with each other and the original diagnosis. This peer review indicated a fair inter-observer agreement (0.482) among 7 pathologists in the department, with fair to moderate agreement when the results were compared to the reported diagnosis, comparable to the published literature. Dual and sub-specialty reporting are being instituted to improve the performance in this vital aspect of pathology.
