This study analyzed readers' responses of children of families with immigration background on children's literature that describes similar life experiences with the readers, based on Brooks & Browne's Culturally Situated Reader Response Theory. Six children between 10 and 16 met the researcher three times each, and read along four different texts about multiculturalism in Korea. The texts include On the Road Together, a picture book, and three short stories in The Black Egg. Participating children showed various ethnic identities - identity as a Korean; identity as a foreigner; identity between a Korean and a foreigner; identity as a child of a multicultural (bicultural) family. The children empathized with the characters or showed their frustrations against racism portrayed in the texts. The four texts used in this study worked as a mirror that reflects each child's own self, and further allowed the children to contemplate their own identities and speak out about their deepest thoughts and feelings. The children were dissatisfied with the main characters' powerlessness and depressing endings of the stories. They wanted the characters with immigration background to be positive and bright, and expected stories about peaceful relationship between children of families with immigration background and children with non-immigration background.

The purpose of this study was to confirm how the students have responded to their class according to STEB (science teaching efficacy belief) of secondary science teacher in astronomy classes. Middle school teachers in charge of 'The Solar System' and 'The Exosphere and Space Development' in the 2009 Revision Science Curriculum content system is selected as an object of study through random sampling method. Twenty-nine teachers were taken STEB questionnaire and asked to make it out. Twenty-seven completed a questionnaire of them is selected for this study. In addition, the top and bottom 5% selected through frequency analysis with the total score from the questionnaire were regarded as high and low STEB teachers. For data collection, this study was used methods such as semi-structured interviews, recording, participant observation. The results were as follows: First, science teachers of high STEB had a high accessibility about excellent professional knowledge and content of the curriculum relating to astronomical field. Second, high STEB teachers were prepared by the appropriate teaching strategies adequate to student-centered learning, whereas the low STEB teachers totally have had teacher-centered learning. Third, high STEB teachers had been provided as the idea that you can take advantage of a variety of instruments, as well as scientific knowledge through the Astronomical Society. Therefore, confidence in astronomical class and teaching strategies through content of the curriculum were very important variables to predict the STEB as well as astronomy-related class activities such as astronomical observations.

The purpose of this study was to develop a school violence prevention program featuring the Practical Action Teaching Model(hereafter, PATM) for middle school students to prevent school violence by Home Economics Education. To accomplish this purpose, the processes of analysis, design, development, and evaluation based on ADDIE were conducted. The validity of the program was evaluated twice by Home Economics education experts(36 experts for the first group and 10 experts for the second group) and the contents of the program were modified according to the comments from the evaluators. The school violence prevention program in Home Economics classes consisted of 5 topics such as changing perception on school violence, enhancing self-esteem, relating with others, practicing consideration and sharing, and strengthening the will of preventing school violence. Twenty-four units were developed with 7 practical problems(What should I do to make friends to help with each other?, What should I do to establish positive self-concept?, What should I do to communicate to build good relationship?, What should I do to solve the conflicts peacefully?, What should I do to practice consideration and sharing in food consumption?, and What should I do to practice consideration and sharing in clothing?) in 5 topic areas. Teaching-learning plans included four steps such as problem perception, practical reasoning, action, and evaluation that comprise PATM to solve the practical problems. Every step of the teaching-learning plan consisted of questions for practical reasoning and activity assignments. Materials for students and teachers were developed. Materials for students comprised 80 pieces in total including student activity, reading, movie, and clips to make students enhance understanding and interest. Materials for teachers comprised 35 pieces in total such as rationales, newspaper articles, and movies that make teachers that lesson teaching loads and were helpful for teachers. The PATM was incorporated into developing the program and a Likert-scale was used to assess usefulness, applicability, appropriateness, fidelity, substantiality, and validity of this program. This program gained more than 4.00 on a 1-5 Likert scale. This result indicated that program is expected to be effective and useful to school violence prevention.

In this study, the flexural test for reinforced high performance fiber reinforced cementitious composites (R/HPFRCC) members has been conducted in order to investigate the flexural behavior including the effect of an ordinary tensile reinforcing bar. Through the test, it was observed that the flexural strength increased due to the stable tensile stress transfer of HPFRCC, even up to the ultimate state. In addition, no localized crack appeared until the yielding of the reinforcement. From the layered section analysis of the tested members, it was found that the analysis with the tensile model obtained from the tension stiffening test showed better agreement with the flexural test results, whereas the analysis with direct tension test results overestimated the flexural capacity. Through the experimental and analytical studies, two flexural failure modes have been defined in this paper; concrete crushing at the top compression layer or tensile failure at the bottom tensile layer of the beam section. Based on these two flexural failure modes, a simple formula that estimates the ultimate flexural strength of the member has been proposed in this paper. The proposed equations can be useful in a design and an analysis of R/HPFRCC members.

This study examined the protective effects of ginger and processed (Beopje) ginger extracts on gastritis induced by HCl-ethanol in SD-rats. Beopje (or Poje) is a branch of herbal medicines processed using a Korean traditional method to achieve specific pharmacological effects. Gastric lesions were induced in the rats by a treatment of 1 mL of HCl-ethanol (60% ethanol＋150 mM HCl). The rats were divided into seven groups: Normal (1 mL of saline without HCl-ethanol treated group), Control (HCl-ethanol treated group), GL (35 mg/kg of ginger treated group), BGL (35 mg/kg of Beopje ginger treated group), GH (350 mg/kg of ginger treated group), BGH (350 mg/kg of Beopje ginger treated group) and Cimetidine (80 mg/kg of cimetidine treated group). The gastric injury inhibition rate was 40.2% and 64.9% in GL and BGL and 68.4% and 99.6% in GH and BGH respectively, showing significantly lower rates than the control (p<0.05). The level of gastric juice secretion decreased significantly in all ginger administered groups. The pH of the gastric juices of BGH increased and the acidity of BGH and cimetidine decreased significantly (p<0.05) compared to the other groups. Beopje ginger had stronger inhibitory effects on gastritis than ginger without the Beopje process. The protective effect on gastritis by the ginger and Beopje ginger extracts increased in a dose-dependent manner (p<0.05). These results suggest that ginger has inhibitory effects on HCl-ethanol induced gastritis in rats that can be improved through the Beopje process.

The GIUH (Geomorphologic Instantaneous Unit Hydrograph) is to be applied to the ungauged or insufficiently gauged basins. For tIris purpose, an accurate estimation of the charactenstlc velocity is one very important part, but any proper method for this has not been developed yet. In case that we have enough rainfall and runoff clata, the estimation of the characteristic velocity may be an easy job, but it is out of the purpose of the GIUH. Remindmg that the purpose of GIUH the characterisbc veloclty should be estimated based on the geomorpholog1c analysis and also be snnple for easy apphcation. In tIris research analysis cmd application of the GruH was given to several sub-basins in Wi-stream river basin, Gono, Donggok and Hyoryung. After deriving the characteristic velocity througn a optimizatlOn process with real data, it is compared w1th several velOCIties der1ved from geOlnoI1Jhoclimatic instantaneous unit hydrograph theory and several other concentration time formulae. The estimated charactenstic velocities using Kerby, Kim, KInematic Wave, and Brasby- Williams formulae found to g1ve the appropriate results. Hmvever, as the Kerby, and the Kinematic Wave require user's decision of the IvIanning's n value, the K1m and the Braby-Williams seem to be more applicable and recommended as characteristic velocity formula.

Korean youth spend tremendous time in school for preparing for college admissions. Their academic achievement and overall satisfaction with their lives are affected by how well they adapt to life in school. Successful adaptation to school is important enough to affect a student's future social life. One of the factors that affect adaptation to school is the psychological condition of adolescent anxiety. Anxiety is one of the common mental disorders that appear in people who are not familiar with new environments. Anxiety is known to be related to behavioral problems, and problems with psychological and emotional adaptation. This condition is dramatically increased in adolescents.Parental conflict in particular is known to be a major factor in affecting youth anxiety. As parental conflict became more severe, children felt more negative emotions such as anger, sadness and worry. Moreover, when a child's issue caused the parental conflict, there were more side effects in the emotional condition of the child. This study shows how parental conflict affects a child's anxiety and a child's school life.This problem is analyzed through structural equation modeling.

Distributed Models have relative weak points due to the amount of computer memory and calculation time required for calculating water flow using a numerical analysis based on kinematic wave theory when compared to the conceptual models used so far. Typically, the distributed models have been mainly applied to small basins. It was necessary to decrease the resolution of the grid to make it applicable for large scale watersheds, and because it would take up too much time to calculate using a higher resolution. That has been one of the more difficult factors in applying the model for actual work. In this paper, MPI (Message Passing Interface) technique was applied to solve the problem of calculation time as it is one of the demerits of the distributed model for performing physical and complicated numerical calculations for large scale watersheds. The comparison studies were performed a single domain and a divided small domain in Yongdam Dam watershed in case of typoon 'Ewiniar' at 2006. They were compared to analyze the application effects of parallelization technique. As a result, a maximum of 10 times the amount of calculation time was saved but keeping the level of quality for discharge by using parallelization code rather than a single processor.

Over the past couple of decades, we can see the emergence of a new lex mercatoria. It consists of international conventions or treaty, model laws and international principles. And such new lex mercatoria is driven by the international institutions such as UNCITRAL, UNIDROIT and ICC. The international convention and international principles in the field of international commercial transaction are considered : UN Convention on Contracts for the International Sale of Goods(CISG) and The UNIDROIT Principles(PICC Principles). The former is the statue law for the latter, and the latter sometimes supports the former as an interpretation and supplementation of CISG. So, the purpose of this article is to evaluate and investigate the current status of CISG and PICC Principles in terms of application and interpretation principles. The results are as follows. First, PICC are used for the interpretation and supplementation of international law such as CISG, but CISG is a law, not a rule. Second, CISG and PICC Principles are not often chosen when parties chose the law governing their contract. The parties very often chose a national law ; the number of the parties choosing CISG and PICC Principles as a governing law was very low.
