Objectives This study aimed to evaluate the effect of Samryungbaekchul-san on childhood anorexia. Methods We searched 11 English, Korean, Chinese, and Japanese databases for studies published up to May 30, 2022. Randomized controlled trials (RCTs) assessing the effect of Samryungbaekchul-san on childhood anorexia were included. In the meta-analysis, relative risk (RR) and 95% confidence intervals (CI) were indicated as dichotomous variables, and mean difference (MD) or standardized mean difference (SMD) and 95% CIs were indicated as continuous variables. Results We included 12 RCTs with 1345 participants. The Samryungbaekchul-san treatment group had a significantly higher total effective rate (TER) than that of the western medicine control group (RR 1.42, 95% CI 1.23-1.64, I² = 0%). The combined Samryungbaekchul-san and western medicine treatment group had significantly higher TER (RR 1.31, 95% CI 1.23 to 1.40, I² = 0%) and levels of neuropeptide Y (SMD 0.93, 95% CI 0.47-1.39, I² = 70%) and ghrelin (SMD 1.45, 95% CI 1.14-1.76, I² = 0%) than those of the western medicine alone group. Additionally, leptin levels were significantly lower in the combined treatment group (SMD -1.19, 95% CI -1.88 to -0.51, I² = 86%) compared with the western medicine alone group, although statistical heterogeneity was substantial. Conclusions Samryungbaekchul-san may be effective for childhood anorexia. However, owing to limitations such as high clinical heterogeneity between the studies, unclear risks of biases, and insufficient reports of adverse events and follow-ups, well-designed RCTs with a low risk of bias are needed in the future.

Objectives: This study aimed to assess the clinical evidence supporting the use of acupuncture (AC) for premenstrual syndrome (PMS). Methods: We searched randomized controlled trials (RCTs) that used AC for PMS in 9 databases (PubMed, EMBASE, Cochrane Library, CINAHL, CNKI, CiNii, SCIENCE ON, KoreaMed, OASIS) from their inception to July 2022. Results: We identified 1,168 studies, of which 15 RCTs met the inclusion criteria. The risk of bias in the included studies was relatively unclear or high. Meta-analysis of 3 RCTs showed that the AC group had a significantly higher effective rate than the Medroxyprogesterone group (RR 1.48, 95% CI (1.23, 1.78), p<0.0001). Meta-analysis of 2 RCTs showed that there was no statistically significant difference between the AC group and the Sham AC group in the effective rate (RR 4.72, 95% CI (0.88, 25.36), p=0.07). In a review of individual studies, the AC group was more effective than the control group in terms of the effective rate, symptom scale, quality of life, adverse events, and recurrence rate. Conclusions: The AC group was more effective than general treatments groups such as sham AC, western medicine, and dietary supplements, and there were no serious adverse events. However, the evidence on the effectiveness and safety of acupuncture for PMS was inconclusive due to the small number of included studies and low quality. Therefore, systematic reviews based on more rigorously designed randomized clinical trials are needed in the future to properly evaluate the effect of AC on PMS.

This study aims to develop and apply a metaverse-based instructional design model for the education in science and technology. It analyzed the concept and characteristics of metaverse, existing non-contact education models, and major teaching strategies systematically. Based on the prior researches, an instructional design model using metaverse is developed that presents metaverse-related teaching strategies and design principles for the before-, during-, and after-lesson phases. Then, this model was applied to a project-based learning program, conducted a perception survey on instructors and learners, and revised the metaverse instructional design model based on the results of the survey. In the Metaverse Instructional Design Model, before-lesson phase is a physical and psychological preparation stage for class participation, which includes familiarization with the Metaverse learning environment, formation of expectations for education, and self-directed pre-learning. During the lesson, to effectively deliver the lesson content, it is necessary to build confidence in the learning environment, promote learning participation, provide reference materials, perform team projects and provide feedback, digest learning content, and transfer learning content. The after-lesson phase provides strategies for ongoing interaction between learners and mentors. This study introduces a new instructional design model that utilizes metaverse and shows the potential of metaverse-based education in science and technology. It also has important implications in that it provides practical guidelines for the effective design and implementation of metaverse-based education.

River estuaries are dynamic and productive ecosystems with high regional biodiversity. Environmental DNA (eDNA) has become a useful approach to assessing biodiversity in aquatic ecosystems. This study was conducted to investigate fish community characteristics and species diversity in two river estuary ecosystems, the Taehwa River and Changwon Stream. We further compared conventional and eDNA metabarcoding analyses of the fish communities. The conventional survey was performed in May, July, and October 2022, while the eDNA analysis was conducted only in May. We observed various fish species with different life histories, including carp, goby, and marine fish. We also found that migratory fish, such as dace Tribolodon hakonensis, sweetfish Plecoglossus altivelis, and eel Auguilla japonica, occurred in the Taehwa River, suggesting high river connectivity. Marine fish species were predominant in the Changwon Stream, as this river is located close to the sea. The diversity indices showed that the Taehwa River generally had higher species richness, evenness, and diversity values than the Changwon Stream. A total of 9-19 species were detected in the conventional survey for the three sites, whereas 11-18 species were found from eDNA analysis. The findings indicate that the sensitivity of eDNA was similar to or higher than that of the conventional method. Our study findings suggest the efficiency and efficacy of eDNA-based fish community monitoring, although with some shortcomings in applying the genetic marker to Korean fish, including no clear-cut distinction for Korean endemic species and/or genetically closely related species groups.

As the electronic medical records systems (EMRs) are introduced into the hospitals in Korea and the needs of chief stakehoders of medical records are changed, the environments related to creating and managing medical records has been changed dynamically. At this moment it might be meaningful to examine medical records based on records management principles rather than information management principles. The purpose of this paper is to apply the KS X ISO 1549 standards, which covers the principles of records management, to hospital medical records management and assess the current quality of medical records management, and define a few tasks of improvement for hospitals. To achieve this goal, this study has performed following activities: Firstly, principles that could be applied to medical records management were prepared for each record management steps described in the standards, such as capture, registration, classification, storage, access, trace and disposition, and 22 principles were selected from those 7 steps of the record management. Secondly, the Y hospital, which is affiliated with a medical school in Seoul, was chosen to evaluate the current situation regarding medical records management. The department head of the medical records management team in Y hospital was interviewed and the present status was evaluated according to each principle. Thirdly, tasks for improvement were suggested, in such stages as access, trace and disposition. With this study as a cornerstone, useful implications are expected to be gathered from future studies that apply standards for metadata of records, management systems for records, and record management systems to medical record management in hospitals.

중등 교육의 질을 확보하기 위한 가장 핵심적인 변인은 교사이며 교사의 자질 향상과 전문성 개발은 교육에 있어 중요한 화두이다. 교사의 전문성은 무엇보다도 교사의 가르치는 능력에서 확보되어야 하며 교과 내용 지식의 확보가 이를 위한 첫걸음이라고 할 수 있다. 본 연구에서는 수업과 심층면담에서 드러나는 초임 교사의 내용 지식(knowledge), 실천 행위(practice), 의미 이해 전략(sense-making strategy)을 분석하여 교사의 과학 내용에 대한 전문성을 파악하는 것을 목적으로 한다. 이를 위해 수도권의 중등학교에서 근무하는 여섯 명의 중등 초임 과학교사를 대상으로 각각 두 차례의 수업 관찰과 구조화된 면담, 한 차례의 우선순위 면담을 실시하였으며, 미시건 주립대학의 Knowles팀에서 개발한 분석틀을 사용하여 질적으로 분석하였다. 본 연구의 결과는 다음과 같다. 첫째, 초임 교사들은 그들이 지향하는 교사상에 따라 과학 교수 활동에 대해 다양한 의도를 가지고 있었으며 비전공 교과의 과학 내용 지식에 대해서는 다소 어려움을 표현하고 있었다. 둘째, 연구에 참여한 교사들은 대체로 교과서에 의존하여 교육과정에서 제시한 내용과 교과서에 제시된 지도 방법에 크게 의존하여 수업을 진행하고 있었으며 교과서 수준의 개념을 중심으로 나열하는 방식을 주로 사용하였다. 다만, 교사가 스스로 재구성한 내용을 바탕으로 자신의 내러티브로 이끌어가려는 시도가 드러나기도 하였다. 셋째, 학생들의 내용 이해를 돕기 위하여 중요한 과학적 개념을 강조하고 그러한 개념을 반복하는 전략을 주로 사용하였다. 그러나 일부 초임 교사의 사례에서는 적절한 비유와 예시를 도입하려는 시도가 발견되기도 하였다. 한편, 연구에 참여한 초임 교사들은 모두 전문성 개발을 위한 노력이 필요하다고 인식하였으며 교사 양성 과정에서 교직과 관련하여 실제적인 도움을 줄 수 있는 프로그램 개발의 필요성을 주장하였다.주로 나타났으며 우리나라 교육과정수업에서는 DC-DP DP-AD맥락의 반성적 탐구가 나타났다. 정리활동에서 우리나라 교육과정은 반성적 교육과정보다 자료 맥락의 영역개념을 더 자주 이용하고 다양한 맥락의 반성적 탐구가 나오고 있으며, 이는 우리나라 교육과정의 학습지의 활동이나 문제는 학생들에게 익숙하고, 자료 패턴을 가지고 행동결정으로 연결짓는 활동이 명확히 제시되었기 때문이라고 판단된다. 두 그룹의 상호작용 특징에 따른 반성적 탐구의 성향의 차이는 도입단계에서 그룹의 특징과 상관없이 A-AD, AD-SR맥락의 반성적 탐구가 나왔으며 전개와 정리단계에서는 N그룹에서는 DP와 관련된 의미 있는 반성적 탐구가 나오는 반면 M그룹에서는 이러한 맥락의 반성적 탐구는 아주 드물게 나타나며, GN과 관련된 행동결정이 자주 보이고 있었다. 정리활동시 주로 하는 기록 활동에서 N그룹에서는 다양한 맥락에서 반성적 탐구를 하고 있는 것에 비해 비교 그룹에서는 서로 견제하고 확인하는 상호작용의 특징에서 나타나는 AD-SR맥락의 반성적 탐구가 자주 나타났다. 반성적 탐구 척도 두 그룹을 비교 했을 때 CON 상호작용의 특징이 낮게 나타나는 N그룹이 양적으로 그리고 내용적으로 더 의미 있는 반성적 탐구를 했다용을 지원하는 홈페이지를 만들어 자료 제공 사이트에 대한 메타 자료를 데이터베이스화했으며 이를 통해 학생들이 원하는 실시간 자료를 검색하여 찾을 수 있고 홈페이지를 방분했을 때 이해하기 어려운 그래프나 각 홈페이지가 제공하는 자료들에 대한 처리 방법을 도움말로 제공받을 수 있게 했다. 실시간 자료들을 이용한 학습은 학생들의 학습 의욕과 탐구 능력을 향상시켰으며 컴퓨터 활용 능력과 외국어 자료 활용 능력을 향상 시키는데도 도움을 주었다.지역산업 발전을 위한 기술역량이 강화될 것이다.정 ${\rightarrow}$ 분배 ${\rightarrow}$ 최대다수의 최

In modern distributed enterprise applications that have multilayered architecture, business entities are a kind of crosscutting concerns running through service components that implements business logic in each layer. When business entities are modified, service components related to them should also be modified so that they can deal with those business entities with new types, even though their functionality remains the same. Our previous paper proposed what we call the DTT (Data Type-Tolerant) component model to efficiently process the variability of business entities, which are data externalized from service components. While the DTT component model, by removing direct coupling between service components and business entities, exempts the need to rewrite service components when business entities are modified, it incurs the burden of implementing data type converters that mediate between them. To solve this problem, this paper proposes a method to use ontology as the metadata of both SCDTs (Self-Contained Data Types) in service components and business entities, and a method to generate data type converter code using the ontology. This ontology-based DTT component model greatly enhances the reusability of service components and the efficiency in processing data variability by allowing the computer to automatically generate data type converters without error.

This study examined research data management practices from the perspectives of university researchers. A survey was conducted for principal investigators of projects in universities selected to be funded by National Research Foundation in 2010 and 2011. Predicated on the analysis of 131 survey responses, there was a great difference in types of research data between Humanities & Social Science fields and Science, Medicine and Engineering fields. Most respondents added value of their data by linking to other types of information or combining data from other sources. For storing data, PC or portable media were generally employed, and around 80% of respondents saw their data having a useful life under 10 years. Data was shared within research team and with outside researchers who requested data. The percentage of respondents who have reused data was higher than that of respondents who have shared data. In order to obtain data for reuse, the majority of respondents drew data from published articles, or contacted data creators. In most cases, mechanisms for managing data did not exist in projects or universities where respondents belong. Since the level of satisfaction with long-term preservation and metadata description of research data was found to be low, it was necessary to develop data archiving services to support the data management procedures.

3D animation production has had a pivotal position in current animation industry and the necessity of professional management tool for 3D animation production has claimed due to its sophisticated pipeline from advance of technology and global production partnership trend. Shotgun and Ftrack are providing the most appropriate management toolset for 3D animation management among the extant management tools and the efficiency of Shotgun & Ftrack is identified compared with the traditional document oriented management style. The biggest strength of production management using Shotgun is that all of the production staff can directly participate in the communication on the tools therefore they can share the information on Shotgun & Ftrack in real time without constraint of time and location. Moreover, all the process of the production and the history of the discussion on certain production issues are systematically accrue on the tool so that the production history can be easily tracked. Finally, the production management using tools contributes collecting and analysing the production information for the production management team in studios. However, Shotgun & Ftrack has metadata based retrieval method which cost huge amount of effort by human's manual annotation and it also has the limitation of accuracy. In addition, the fact that studios has to have technical professionals first in order to institute the tools into their studios is the actual difficulty of Korean studios when they want to use management tools for their project. Thus, this paper suggests adopting the content-based retrieval system on the tools and tools' expanded technical service for the studios as the solution of the identified issues.

The extant research literature is scant in telling us how organizations actually implement lifelong learning practices and policies. Hence, the purpose of this paper is to describe how lifelong learning is grounded in practice. We do this by introducing a new conceptual framework that was developed on the basis of interviews with a number of leading edge corporations from Canada, the USA, India and Korea. At the heart of our model, and any effective lifelong learning system, is a performance management system. The performance management system allows for an ongoing interaction between managers and employees whereby challenging performance and learning goals are set, and concrete plans are made to achieve them. Those plans involve three types of learning activities. First, employees may be encouraged to engage in formal learning. This could be provided in-house, or the employee may take a leave of absence and return to school. Second, managers may deploy their subordinates to different departments or teams, so that they can take part in new work-based learning opportunities. Finally, employees may be encouraged to learn on their own time. By this we mean learning after organizational hours through firm-sponsored 5 programs, such as e-learning courses. Fueled by the performance management system, we posit that these three learning outlets lead to effective lifelong learning in organizations.
