<P><B>Abstract</B></P> <P>As Function Block Diagram (FBD) programs are used to implement safety-critical systems such as nuclear reactor protection systems, it is crucial to generate effective test cases. FBD programs are running on programmable logic controllers (PLCs) that execute the programs repeatedly within a particular scan time. Among the elements of FBD programs, function blocks and feedback variables save the inputs or outputs of the previous scan cycle into internal memories. The data stored in the internal memory are used to operate the function blocks of the next scan cycle. Researchers have recently developed an automated test generation technique aiming to satisfy several structural test coverage criteria for FBD programs. Among them, Jee et al.'s approach has an advantage of generating tests from FBD programs without requiring any intermediate models. However, test sequence generation for FBD programs with internal memory states was not fully automated in Jee et al.'s approach. This paper extends Jee et al.'s work by generating test sequences from FBD programs with internal memory states in a fully automated manner. The key technique involves explicitly unwinding FBD programs and solving the test requirements using an SMT solver. We conduct experiments on increasing the coverage of test requirements by unwinding cycles and evaluating the effectiveness of the test set using mutation analysis with several subject programs, including a real-world reactor protection system. The experimental results show that the proposed approach is able to generate effective test sequences for FBD programs. To demonstrate the efficiency of the proposed approach, we compared the test sequence generation time required for our approach with those for other approaches. The comparison results show that even excluding the generation time of test models of other approaches, the proposed approach increased the time-efficiency by more than 11 times.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Developing algorithms to generate test sets for Function Block Diagram programs. </LI> <LI> Defining Function Block Conditions for all the standard function blocks. </LI> <LI> Implementing an automated test sequence generation tool using Yices SMT solver. </LI> <LI> Demonstrating improved fault-detection effectiveness and time efficiency. </LI> </UL> </P>
이전 연구(Jee & Park, 2013)에서, 일반 가정에서 가족활동을 통해 과학 창의성을 향상시키기 위한 활동자료를 개발하고 적용하였다. 이를 위해 12 가족을 두 구룹으로 나누어 각각 6개의 과학 창의성 프로그램으로 제공하여 주당 한 개 프로그램씩 6주간 실시하도록 하였다. 그 결과 참가자들로부터 다양한 긍정적인 반응을 얻을 수 있었다. 본 연구에서는 이전 연구에 이어서, 가정에서의 가족활동을 통해서 과학 창의성이 향상되는지를 정량적으로 검증해 보고자 하였고, 가정에서의 창의성 지도 가능성에 대한 학부모의 의견을 알아보고자 하였다. 이를 위해, 사전 및 사후조사에서 사용할 각각 3개 문항으로 구성된 과학 창의성 조사 도구를 개발하여 적용하였다. 이 도구에는 Park(2011)이 정의한 다양한 과학 창의성 요소들이 포함되도록 하였다. 학부모 의견을 알아보기 위해서는 설문지를 개발하여 적용하였다. 실시 결과, 학부모들은 기본적인 방법만 습득하면 누구나 과학 창의성 활동을 수행할 수 있으며, 효과적인 프로그램만 있다면 가정에서도 수행할 수 있다는 인식으로 변화된 것으로 나타났다. 또 창의성 평가를 통해서도 실험집단이 통제집단에 비해 통계적으로 유의미하고 효과의 크기도 매우 크게 창의성이 향상된 것으로 나타났다. 이를 통해 앞으로 과학 창의성 활동을 가정 내에서 뿐 아니라, 캠프나 여가활동 중 또는 과학관 등에서 가족형 프로그램으로 확대 적용될 수 있을 것으로 기대되었다. In the previous study (Jee & Park, 2013), family activities, which can be utilized to improve scientific creativity at home have been developed and used. In that study, 12 families fell into two groups, received 6 programs for scientific creativity respectively, and conducted the program for six weeks. As consequences, various positive responses from participants have been received. This survey has been conducted to test whether scientific creativity could be improved quantitatively through family activity at home, and to examine parents` recognition of the feasibility of teaching creativity as well. To answer this, a scientific creativity test consisting of three items in the pre- and post-test respectively have been developed and carried out. The test includes various elements of scientific creativity defined by Park (2011). For obtaining parents` responses, a questionnaire has been developed and applied. The results reveal that parents have changed their thought to ‘everyone can conduct scientific creativity activity at home if effective programs are provided and they learn the basic skills to do it.' And, through the scientific creativity test, the experimental group has indicated an improvement in scientific creativity with statistical significance and a large effect size. Therefore, we suggest that family activity for scientific creativity can be applied to family activity in various situations such as camp, leasure or science museum.
The 15,389-bp long complete mitogenome of the endangered red-spotted apollo butterfly, Parnassius bremeri (Lepidoptera: Papilionidae) was determined. This genome has a gene arrangement identical to those of all other sequenced lepidopteran insects, which have the gene order of tRNAMet, tRNAIle, and tRNAGln at the beginning. Due to the uncertainty the start codon for COI gene in insect has been discussed extensively. We propose the CGA sequence as the start codon for COI gene in lepidopteran insects, based on complete mitogenome sequences of lepidopteran insects including our P. bremerii and additional sequences of the COI start region from a diverse taxonomic range of lepidopteran species (a total of 51 species belonging to 15 families). As has been suggested in other sequenced lepidopteran insects the 18 bp-long poly-T stretch and the downstream conserved motif ATAGA that were previously suggested to serve as a structural signal for minor-strand mtDNA replication also was found at the 3'-end region of the P. bremerii A+T-rich region. In an extensive search to find out tRNA-like structure in the A+T-rich region, each one tRNATrp-like sequence and tRNALeu (UUR)-like sequence were found in the P. bremeri A+T-rich region, and most of other sequenced lepidopteran insects were shown to have tRNA-like structure within the A+T-rich region, thereby indicating that such feature is frequent in the lepidopteran A+T-rich region. Phylogenetic analysis using the concatenated 13 amino acid sequences and nucleotide sequences of PCGs of the four macrolepidopteran suferfamilies together with Tortricoidea and Pyraloidea well recovered a monophyly of Papilionoidea and a monophyly of Bombycoidea. However, Geometroidea and Noctuoidea were unexpectedly clustered as one group and placed this group to the sister group to Bombycoidea, instead of Papilionoidea in most analyses.
Purpose: Renal colic is a common disorder with a high rate of recurrence, resulting in a large number of emergency department visits. The aim of this study was to investigate the seasonal variation in renal colic attacks and the association with climatic parameters. Methods: The time of onset, monthly incidence, and effects of climatic parameters of renal colic were evaluated. Data on climatic parameters were obtained from the Korea Meteorological Administration. Correlation between the number of monthly episodes and climatic parameters was assessed using Pearson`s correlation coefficient. Results: A total of 5060 renal colic episodes were retrieved during a period of 84 months (from May 2006 to April 2013). Episodes of renal colic were more common in men (67.4%) than in women(32.6%). The incidence of renal colic showed a circadian variation, with a morning peak (500~1000 h) and an afternoon dip (1500~1900 h). Findings of the current study showed a higher number of renal colic episodes during summer compared with other seasons. Significant positive correlations were observed between the mean monthly temperature and the monthly incidence of renal colic, but not between other climatic parameters (relative humidity, rainfall, sunshine hours, and atmospheric pressure) and incidence of renal colic. Conclusion: We conclude that the incidence of renal colic has significant seasonal variation, and only mean monthly temperature showed any consistent association with monthly attack rates.
Objective: To determine whether animal age impacts in vitro preantral follicle growth. Effects of hCG, stem cell factor (SCF), and/or insulin-like growth factor (IGF) supplementation in growth medium were also investigated. Methods: Intact preantral follicles were mechanically isolated from fresh ovaries of BDF1 mice and cultured in growth medium for 9 to 11 days. Surviving follicles with antrum formation were transferred to maturation medium for 14 to 18 hours. Follicle survival, antrum formation, and retrieval of metaphase II (MII) oocytes were compared among three age categories (4-5, 7-8, and 10-11 week-old). By using 7- to 8-week-old mice, preantral follicles were cultured in growth medium supplemented with hCG (0, 5, or 10 mIU/mL), SCF (50 ng/mL), IGF-1 (50 ng/mL), and SCF+IGF-1. Results: Seven- to eight-week-old mice showed a higher follicle survival and antrum formation and produced more MII oocytes compared to other groups. In the 7- to 8-week-old mice, supplementation of 5 mIU/mL hCG significantly enhanced the antrum formation but the percentage of MII oocytes was similar to that of the control. Supplementation of SCF+IGF-1 did not enhance follicle survival or antrum formation but the percentage of MII oocytes increased modestly (39.1%) than in the control (28.6%, p>0.05, statistically not significant). Conclusion: Seven- to eight-week-old mice showed better outcomes in growth of preantral follicles in vitro than 4- to 5- or 10- to 11-week-old mice. Supplementation of hCG enhanced antrum formation and supplementation of SCF+IGF-1 yielded more mature oocytes; hence, these should be considered in the growth of preantral follicles in vitro.

Hyun-jee Kang and Myungki Oh. 2018. A Study on Joke Misinterpretation in L2 Settings: Viewed from The Benign-Violation Theory. Studies in Modern Grammar 99, 161-176. This paper examines cases in which Korean college students might misinterpret superiority, incongruity, and sarcastic English jokes. In parallel the writer tries to bring to light possible background reasons for their misinterpretation from the perspective of the Benign-Violation Theory' concepts of norm violation, commitment, and psychological distance. Arguably Korean college students are likely to misinterpret English humor codes influenced by their ingrained belief system of strict moral standard as well as insufficient exposure to particular genres of English jokes.
