It is a well-known fact that most of the Korean school buildings has been adjusted by the standard plan according to the united and unified teaching method ever since the modern education started. However, seeing the recent growth of care for the open education, the effort to improve the teaching method in school fileds, the practice of the 6th education plan and the education reformation, it can be said that it is high time to change. As the number of schools which practice the open education has been increasing since in 1985 in this atmosphere, there have also appeared elementary schools with the open school building. But the general understanding of the school building and the open space is not enough. Therefore, this study aims to analyze the general spacial conditions, such as the fresh and diverse types of learning method and their development and the concept of the open space along with its types, application, size, and constition by studying, from the standpoint of the building plan, the elimentary schools of a new type in Japan which adopted the open space 20years earlier than in Korean. This study can offer helpful suggestions as to the Korean school building because our situation is very similar to the early stage where the open space is adopted to the school building.

Objective: This study aimed to examine the moderating effect of elementary school students' perception of open communication with their parents in relationship to smartphone dependency and school adjustment. Methods: Participants included 300 fifth and sixth graders attending P and A elementary schools in Gyeonggi Province. Descriptive analysis, correlation analysis, and hierarchical regression analysis were performed to analyze data. The level of significance was set at p < .05 for all analyses. Results: The results of the present study are as follows: First, male students showed higher levels of smartphone dependency than female students, and students' smartphone dependency increased according to age. The students' smartphone dependency was negatively associated with their school adjustment and their perception of open communication with their parents. Second, the students' perception of open communication with their fathers was found to moderate the relationship between smartphone dependency and school adjustment. Conclusion/Implications: These findings indicate that open communication between parents and their elementary school-aged children can buffer the adverse effects of smartphone dependency on school adjustment. This study provides implications for parent education and counseling to improve parent-child communication and subsequently build strong, positive family relationships.

Background: The purpose of this study was to identify demographics and risk factors associated with unplanned 30-day readmission and reoperation following open procedures for shoulder instability and examine recent trends in open shoulder instability procedures. Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried using current procedural terminology (CPT) codes 23455, 23460, and 23462 to find patients who underwent shoulder instability surgery from 2015 to 2019. Independent sample Student t-tests and chi-square tests were used in univariate analyses to identify demographic, lifestyle, and perioperative variables related to 30-day readmission following repair for shoulder instability. Multivariate logistic regression modeling was subsequently performed. Results: In total, 1,942 cases of open surgical procedures for shoulder instability were identified. Within our study sample, 1.27% of patients were readmitted within 30 days of surgery, and 0.85% required reoperation. Multivariate logistic regression modeling confirmed that the following patient variables were associated with a statistically significant increase in the odds of readmission: open anterior bone block/Latarjet-Bristow procedure, being a current smoker, and a long hospital stay (all P<0.05). Multivariate logistic regression modeling confirmed statistically significant increased odds of reoperation with an open anterior bone block or Latarjet-Bristow procedure (P<0.05). Conclusions: Unplanned 30-day readmission and reoperation after open shoulder instability surgery is infrequent. Patients who are current smokers, have an open anterior bone block or Latarjet-Bristow procedure, or a longer than average hospital stay have higher odds of readmission than others. Patients who undergo an open anterior bone block or Latarjet-Bristow procedure have higher odds of reoperation than those who undergo an open soft-tissue procedure. Level of evidence: III.

멀티프로세서 환경에서 OpenMP는 MPI 에 비해 병렬 프로그래밍을 쉽게 할 수 있다는 장점을 가지고 있고, OpenMP는 표준이 없는 병렬 프로그래밍 세계에서 실질적인 표준으로써 인정받고 있다. OPenMP는 대상 플랫폼에 따라 OpenMP 구현을 다르게 해야 하기 때문에 새로운 프로세서가 등장하면 그에 맞는 OpenMP구현을 만들어야 한다. 이 논문에선 다중 프로세서 시스템-온-칩 시스템인 ARM11MPCore 시스템 위에 POSIX 쓰레드에 기반하여 OpenMP 환경을 구축하고 그 성능을 측정한다.

Network virtualization enables us to make efficient use of resources in a physical network by embedding multiple virtual networks in the physical network. In this paper, we develop a prototype of a virtual network embedding system. Our system consists of OpenStack, which is an open source cloud service platform, and shell scripts. Because OpenStack does not provide a quality of service control function, we realize bandwidth reservation for virtual links by making use of the ingress policing function of Open vSwitch, which is a virtual switch used in OpenStack. The shell scripts in our system automatically construct the required virtual network on the physical network using the OpenStack command-line interface, and they reserve bandwidth for virtual links using the Open vSwitch command. Experimental evaluation confirms that our system constructs the requested virtual network and appropriately allocates node and link resources to it.

Skeletal anterior open bite is a difficult problem to correct in orthodontic treatment. To treat adult patients who have skeletal anterior open bite, we considered two methods. Combination treatment of orthodontics & surgery and camouflage orthodontic treatment. In adults, treatment of severe skeletal anterior open bite consists mainly of surgically repositioning the maxilla or the mandible. However, camouflage therapy is often the treatment of choice for skeletal open bite patients who have mild to moderate skeletal discrepancies when growth modification is no longer possible. But excellent results generally require careful coordination of the orthodontic and surgical phases of treatment. This is a case report of a skeletal anterior open bite patients who were treated with orthodontic treatment and orthognathic surgery. First case was diagnosed as skeletal class I malocclusion & bimaxillary protrusion with anterior open bite, and finally treatment ended for removal of open bite with orthodontic procedure and bimaxillary anterior segmental osteotomy surgery. Second case was diagnosed as skeletal class II malocclusion with open bite & mandibular retrusion, and was treated with only camouflage orthodontics because she feared to have a surgery. In a regular follow up visit after debonding we proposed to the patient advanced genioplasty, and in her agreement her facial esthetics was improved through the surgery.

The purpose of this research is to find the effect of the lesson using open-inquiry report Lubric on open-inquiry standard and science process skill; to find the change of cognition on open-inquiry for elementary school 5th grade students. Two classes (elementary school 5th grade) were selected which located in a small and medium-sized city for this research and they were separated as an experimental group and a comparative group. Open-inquiry lesson was done by referring teaching method which introduced through the curriculum. The procedure was understanding about open-inquiry, making open-inquiry subject, planning, and performing inquiry, mid-term, performing inquiry, making a report, presentation, and evaluation. Open-inquiry report Lubric which developed by Sook-Kyung Kim et al. (2010) was provided to the experimental group. Comparative group was instructed by using open-inquiry report which introduced to the elementary school 5th grade science text book. Interview paper was developed in order to check out the effect of the research by using a test paper of science process skill. The following could be found out through the research. After open-inquiry lesson, 10 open-inquiry reports(5 reports from experimental group, 5 reports from comparative group) have been drawn at random as samples from the total 62 sets (30 reports from experimental group, 32 reports from comparative group) and evaluated by a researcher and two elementary school teachers who have master degree. The reliability of the 3 scorers was 0.923 of mean correlation coefficient. And then the researcher evaluated all open-inquiry reports. The average score of open-inquiry report was 66.78 for experimental group, 54.27 for comparative group, respectively. And there was a significant difference at p<0.05 level as a result of the t-test. The experimental group rated high at p<0.05 level according to the analysis of post-science process skill test. According to the result of survey, both experimental group and comparative group had understood open-inquiry activity. It was especially rated high for experimental group on understanding scientific inquiry process, interest and satisfaction in open-inquiry and re-participation rate. By interviewing experimental group, it is recognized that the students utilized Lubric very well through the overall process. Finally, self-evaluation was done during open-inquiry activity and it was reported that the students gained more knowledge about science and changed to positive about science. As a result, the lesson using open-inquiry report Lubric was effective for students to improve writing skill of an open-inquiry report and science process skill and finally changed the cognition to positive about open-inquiry lesson.
