This study aimed to identify the effects of death education programs among Korean aged on death anxiety and attitudes toward death in the convergence era. The searched kew words were included aged, death education program, death anxiety, and attitudes to death in the research papers published in Korea. Finally, 11 studies were selected and the effect size was calculated. Death anxiety and death attitude were selected as dependent variables, and publication type, total duration of intervention, and frequency of intervention were selected as moderator variables. The total of 11 papers were selected to estimate the effect sizes of interventions. As a result, the overall effect size of the death education program for the aged was 1.07. The overall effect size showed death education program was able to lower death anxiety (Hedges' g=1.30, 95% Cl=0.80~1.80, p<.01) and improve attitudes to death (Hedges' g=0.93, 95% Cl=0.49~1.37, p<.01) compared with the no intervention group. In the moderator analysis to identify the cause of heterogeneity, significant results were found in the frequency of intervention. We propose a study that repeatedly verifies the effect of related studies in the future by providing the theoretical basis and basic data for the development of the death education program.

Digital-Twin are recognized as an important core technology for the realization of Smart Factories by simulating and optimizing the monitoring and predictive maintenance of manufacturing equipment and the operation of production lines in a digital space. To implement this system, we adopt the IEC62541-based OPC-UA (Open Platform Communications Unified-Architecture) Protocol, which has strengths in interoperability and connectivity between heterogeneous platforms. Therefore, In this paper, We designed and implemented an IIoT(Industry Internet of Things) system that connects heterogeneous platforms, and developed an OPC-UA simulator based on IEC 62541. We will present whether the data will be applied to the Digital-Twin Platform and whether it will work, and proceed with performance tests and evaluations. We evaluate the operation performance and OPC-UA performance of the Digital-Twin platform lightened by the proposed device, and present the optimal IEC62514-based simulator system. We proceeded with the performance evaluation of sending and receiving data with OPC-UA wrapping with the proposed simulator, and found that a lightweight Digital-Twin platform can be operated. This research can apply the OPC-UA protocol for implementing smart factory and meta-factory in the manufacturing shop floor with limited resources, avoiding the waste of time and space on the shop floor through the OPC-UA simulator. We expect that this will contribute to a significant improvement in efficiency by minimizing.

The purpose of this research is to analyze the effect of an autobiography writing program as a method of education for older adults. The authors participated in the processes of all 10 sessions of the autobiography writing program as instructors or program assistants at a senior welfare center in Seoul, 2007. Data used for analysis were learners' narrations in class, written autobiographies by learners, and researchers' memo-notes. We analyzed their narrative flows using Haenninen(2000)'s theory of narrative flow and reconstructed their categories of activities as life histories. 'The innen narration' constructed by learners was a spiritual process in which they have imbued their life and living conditions with meaning. The learners reminisced their lives as 'unreflective narration' in the beginning of education. However, as the class went on, they gradually reminisced them as "reflective narration" and finally developed them as 'meta-reflective narration' through the intentional reflection. Likewise, we could interpret the transition of learners into meta-reflecter as the completion of ego-integration. As a conclusion, we found the effects of the autobiography writing education for older adults in educational, social, and psychological aspects.

Objectives The aim of this study was to analyze the trends of researches on oriental medicine treatments for supraspinatus tendinopathy. Methods We used five databases for searching researches; Korean studies Information Service System, Oriental Medicine Advanced Searching Integrated System, Research Information Sharing Service, PubMed, and China National Knowledge Infrastructure. Only randomized controlled trials suitable for the subject were selected. The methodological quality of included randomized controlled trials (RCTs) was assessed by the Cochrane risk of bias tool. Results Twenty randomized controlled trials were analyzed. There were 9 types of treatment interventions; acupuncture, acupotomy, pharmacopuncture, electroacupuncture, fire needling, warming needle, catgut-embedding therapy, herbal medicine, cupping. The most frequently used treatment intervention was acupuncture and acupotomy. There were 9 outcome measurements including visual analog scale (VAS), Constant-Murley Score (CMS), and range of motion. The most used measurement was VAS. As a result of meta-analysis, acupuncture was more effective than control group in VAS. Additionally, acupotomy was clinically significant compared to control groups in VAS and CMS. Conclusions In this review, we analyzed researches on effectiveness of oriental medicine for supraspinatus tendinopathy. A provisional conclusion can be produced that acupuncture and acupotomy showed beneficial effect to supraspinatus tendinopathy. Although there were some RCT studies, many of them had a high risk of bias, so it is hard to conclude that our study can include overall clinical status. Further well-designed trials are needed.

The purpose of this study is to review empirical research on Form-focused instruction (FFI) in Korean language education from a critical perspective to better understand the effectiveness of FFI. To achieve this goal, several databases were searched to locate relevant experimental and quasi experimental studies published in peer-reviewed journals. Out of 66 studies collected, 12 studies met the inclusion criteria. The studies were then analyzed in terms of subjects, target grammar, treatment, measurement, and the learning outcomes of different techniques. In general, several types of FFI techniques had positive effects on helping learners acquire Korean as a second or foreign language. The results of the study will provide a conceptual framework which identifies the major factors affecting the effectiveness of FFI. The results will also be able to inform future meta-analytical research of existing studies.

Artificially-engineered materials, whose electromagnetic properties are not available in nature, such as negative reflective index, are called metamaterials (MMs). Although many scientists have investigated MMs for negative-reflective-index properties at the beginning, their interests have been extended to many other fields comprising perfect lenses. Among various kinds of MMs, metamaterial absorbers (MM-As) mimic the blackbody through minimizing transmission and reflection. In order to maximize absorption, the real and the imaginary parts of the permittivity and permeability of MM-As should be adjusted to possess the same impedance as that of free space. We propose a dual-wide-band and polarization-independent MM-A. It is basically a triple-layer structure made of metal/dielectric multilayered truncated cones. The multilayered truncated cones are periodically arranged and play a role of meta-atoms. We realize not only a wide-band absorption, which utilizes the fundamental magnetic resonances, but also another wide-band absorption in the high-frequency range based on the third-harmonic resonances, in both simulation and experiment. In simulation, the absorption bands with absorption higher than 90% are 3.93 - 6.05 GHz and 11.64 - 14.55 GHz, while the experimental absorption bands are in 3.88 - 6.08 GHz and 9.95 - 13.84 GHz. The physical origins of these absorption bands are elucidated. Additionally, it is also polarization-independent because of its circularly symmetric structures. Our design is scalable to smaller size for the infrared and the visible ranges.

This study is to be used for research material for pastoral counseling, by analyzing grounded-theoretically how substance abusers' awareness of self and experience of relations affects problems in abusing drugs. The subject of this study was chosen as 9 prisoners who were able to participate in group counseling, among those who were in prison for substance abuse and had more than 6 months of penal servitude left. In addition, in order to indicate counseling research methods through this study, 12 group counselings were carried out during October 24th. 2002 and February 14th. 2003 and verbatim were written out to be used as original material. After the research material was analyzed, they could be categorized into 60 concepts on the whole from 'conflict' and 'constraining thinking' to 'rationalization' and 'avoidance'. When these concepts were organized into groups of similarity, there were all together 20 categories. From this study, it can be found that substance abusers had "problems about self" and "problems about relations". The factor which affected their use of drugs was the area of relations, where as henceforth their use of drugs, the situation in which they could not escape from the use of substances was affected by problems within the area of self. When facing such problems as substance abuse, the pastoral counselor must create a holding environment through counseling, and perform good enough mothering by being insightful and providing active support on the problem. They must also help one's growth into "an empathizing self", "an accepting self", "a trusting self", "a hopeful self", who can empathize, accept, trust and hope, through experience in separation from the problem, conversion, meta-communication, self-rumination, relations and inspiration of hope. Likewise, the church must be able to act as a "place of growth and skill" which aids in the forming of relations and helps to be aware of self through experience in, and understanding of, relations.

Although research has shown a significant amount of work identifying various dimensions of relevance along with exhaustive lists of relevance criteria, there seem to have been less effort to apply the findings to improve actual systems design. Based on this assumption, this paper investigates to what extent those relevance criteria have been incorporated into the interface features of major commercial Web search engines, suggesting what can/should be done more. Before stepping into the actual system features, this paper compares recent relevance research in Information Science with other human factor studies both in Information Science and its neighboring discipline (HCI), as an attempt to identify studies that are conceptually similar to the relevance research, but not named as such way. Similarities and differences between these studies are presented. Recommendations suggested to support applicable interface features include: 1) further personalization of interface designs; 2) author-supplied meta tags for the Web contents; and 3) extensions of beyond-topical representations based on link structure.

If Industrial state-of-the-art technology that made through IT convergence should be to build safely environment that can protect then IT technology and manufacturing industry become convergence and a growth engine become stable positioning. In each industry, there has been a steady effort for the industrial security. However, they introduced only managerial/technical/physical countermeasures. Therefore, it is difficult to find a reference point as industrial security necessity, protecting coverage and things and so on. It is to lack that academic research in industrial security for protecting industrial technology. In detail, a clear definition lack for industrial security. And target range classification lack for industrial security studies. In this study, we redefined the concept of industry security through previous studies. Academic classification designed industrial security studies through delphi method. we analyzed industry security trends based industrial security studies classification and presented domestic industry research orientations.
