When Web-based special retrieval systems for scientific field extremely restrict the expression of user's information request, the process of the information content analysis and that of the information acquisition become inconsistent. Accordingly, this study suggests the re-ranking retrieval model which reflects the content based similarity between user's inquiry terms and index words by grasping the document knowledge structure. In order to accomplish this, the former constructs a thesaurus and similarity relation matrix to provide the subject analysis mechanism and the latter propose the algorithm which establishes a search model such as query expansion in order to analyze the user's demands. Therefore, the algorithm that this study suggests as retrieval utilizing the information structure of a retrieval system can be content-based retrieval mechanism to establish a 2-step search model for the preservation of recall and improvement of accuracy which was a weak point of the previous fuzzy retrieval model.

Poor project performance has been noted as the bane in the construction industry globally. This paper sought to investigate, by way of literature, the performance patterns of construction projects in Kenya since independence (1963-2018). This was informed by reports of undesirable project performance in the industry. This descriptive study used available studies previously done in this subject area. In sum, literature is replete with evidence on a myriad of challenges facing the execution of projects. The study established that generally, the project performance is poor and has assumed a chronic trajectory spanning over five decades. On average, the findings reveal that 35-60% of projects initiated in Kenya face cost overruns while time overrun is most severe with 35-73% projects overrunning their schedule. In addition, the findings problematize the issue of plurality of performance measurement regimes in the construction industry. Here, it was observed that no singular construct exists to objectively measure the various facets that constitute the 'health' of a project. This paper has contributed to the body of knowledge by examining the performance patterns in Kenya for over fifty years while at the same time identifying the bottlenecks inherent in projects execution. Importantly, the conceptual performance efficiency framework derived in the current study presents a paradigm shift in the monitoring and evaluation of projects. To this end, an in-depth analysis is recommended on the interaction of efficiency enablers in the buildup of performance efficiency index (PEI). Similarly, a further inquiry is recommended on the integration and impact of the proposed framework in the management of projects.

By taking the form of a fictional autobiography, a Japanese American woman writer Lydia Minatoya tries to solve the inexpressible confliction which Japanese Americans experience in their living in America. In her first published fiction, Talking to High Monks in the Snow, the writer faithfully tries to follow the Japanese I-story tradition where meandering of personal petit histories and frequent self-pities are constructed without solid action, characters and plot. Here appear many accidental others whom function as significant yet fleeting subalterns. In contrast, in the second fiction, The Strangeness of Beauty published seven years later, the I-narratives undergoes some drastic transformations by authorial intrusion, dramatic and haiku styles, and appearances of actorial agents. Just working as an invisible yet important stagehand (kuroko in Japanese) behind the stage of life, the author now handles her own self-inquiry through more controllable distance and maturity as directors or photographers often do. However, despite achieving dramatic actions and artistic elegance mainly thanks to her adoption of western masterpieces's grand narratives, Minatoya seems to stop in the midway in her tallying work of fiction with fact by delaying the larger imaginable conflict through which the temporarily gained autonomy can be turned into a disaster anytime. Nonetheless, the reader feels relieved and encouraged after recognizing the fragile Asian female self's transformation as a new, flexible and autonomous self by her unwavering contact with two contrasting cultures and providing silent minority female characters with gradually stronger and uncannier voices.

Prestressed composite steel-concrete beams are still a technology restricted to repair sites of large-scale structures and spans. One of the reasons for that is the absence of standard frameworks and publications regarding their design and implementation. In addition, the primary normative codes do not address this subject directly, which might be related to a scarcity of papers indicating methods of design that would align the two technics, composite beams and external prestressing. In this context, this paper proposes methods to analyze the sizing of prestressed composite beams submitted to pre-tension and post-tension with a straight or polynomial layout cable. This inquiry inspected a hundred and twenty models of prestressed composite beams according to its prestressing technology and the eccentricity and value of the prestressing force. The evaluation also included the ratio between span and height of the steel profile, thickness and typology of the concrete slab, and layout of the prestressing cables. As for the results, it was observed that the eccentricity of the prestressing force doesn't significantly influence the bending resistance. In prestressed composite beams subjected to a sagging moment, the ratio L/d can reach 35 and 30 for steel-concrete composite slabs and solid concrete slabs, respectively. Considering the negative bending moment resistance, the value of the L/d ratio must be less than or equal to 25, regardless of the type of slab. When it comes to the value of the prestressing force, a variation greater than 10% causes a 2.6% increase in the positive bending moment resistance and a 4% decrease in the negative bending moment resistance. The pre-tensioned composite beams showed a superior response to flexural-compression and excessive compression limit states than the post-tensioned ones.

The present article deals with the concept 'ekayāna' as the spirit of the times in the period of Unifying War in Shilla, which is embodied in the thought of Wonhyo and Euisang. This article is divided into five sections. Section I introduces the background of research history regarding the spirit of the age during the Unifying War, and explaines the reason why we adopted two thinkers such as Wonhyo and Euisang, especially the concept 'ekayāna' of the two as a subject for inquiry. Section II discusses on the hermeneutical difference between the Chinese Faxiang sect and Wonhyo regarding the interpretation of one passage from Saṃdhinirmocana-Sūtra, in which the relation between ekayāna and triyāna is explained. It is noteworthy that Faxiang sect places emphasis on the differentiation of triyāna, but Wonhyo gives emphasis to equality of ekayāna. Section III refers to the hermeneutical horizons of Wonhyo which is connoted in the interpretation of Saṃdhinirmocana-Sūtra, especially focusing on the concept 'ekayāna'. Here we can make a conclusion as follows; Firstly, the 'ekayāna' in Wonhyo is immanent in 'triyāna' and at the same time transcendental from 'triyāna', so to speak 'com-transcendetal' with 'triyāna'. Secondly, there is inseparable and unmixable relation between 'ekayāna' and beings. In another words, 'ekayāna' is śūnyatā. Thirdly, 'ekayāna' is a kind of universal truth(普法 pŭ fă) in that it offers the benefit to open and develop the immanent buddhadhātu of all living lives. In addition to Wonhyo's thought on ekayāna, section IV refers to the concept 'ekayāna' of Euisang. On Euisang, 'ekayāna' is 'the perfect teaching(圓敎 yuán jiào)' and 'pratītyasamutpāda'. From this point of view, we can conclude that the thought on ekayāna between the two, Wonhyo and Euisang is not different, and completely coherent. As a result, as it is concluded in section V, it is also clear that ekayāna has 'com-transcendental' relation to triyāna. Therefore we can safely make a conclusion that the spirit of the times in the period of Unifying War in Shilla among the leading thinkers is the vision for 'com-transcendency'.

Article 79 of the Occupational Safety and Health Act mandates franchise headquarters with over 200 franchises to implement industrial accident prevention measures. Notably, the franchise business information provision system designates restaurants and wholesale/retail as the primary categories for information disclosure, with convenience stores classified as secondary. This study aims to identify law-regulated franchise headquarters and franchises and analyze industrial accidents within these sectors. Furthermore, it seeks to investigate adverse risk factors for individual processes across major industries. Pertinent franchise headquarters and franchises were discerned using the Fair Trade Commission's business information system. Data regarding the status of industrial accidents, as published by the Ministry of Employment and Labor, was leveraged in the analysis of industrial accidents. Additionally, a survey was conducted to derive detrimental factors for each process in major industries. The inquiry revealed a total of 7 wholesale and retail franchise headquarters subject to the law, along with 126 within the restaurant industry. Overall, there were 50,488 franchises in the wholesale and retail sector, and 71,283 in the restaurant business. Risk factors and improvement measures for industrial processes were determined for five industries: convenience stores, Korean food restaurants, coffee places, pizza eateries, and chicken vendors. Locating the currently developed safety and health program establishment guide proves to be challenging. Moreover, utilizing it can be difficult due to the industry-specific content, further complicated by the prevalence of franchise stores featuring numerous small businesses. Therefore, this study highlights the imperative need to develop guidelines that incorporate preventive measures tailored to each industry.

The study aimed to investigate a research trend in science gifted education of six years from 2010 to 2015 by utilizing literature analysis and Social Network Analysis (SNA) methods. In this study, 275 papers published in eight major academic journals of science education and gifted education were selected as research subjects. First, through the literature analysis, it was found that the most frequent research topics were cognitive characteristics (25.8%), curriculum/programs (22.6%), and social and emotional characteristics (20.2%). For the research method employed in research papers, the survey research (46.5%) was appeared as the most frequently employed method, and followed by experimental (18.8%), program development (10.6%), correlation (10.3%), and qualitative (6.4%) research methods. The most frequent research subject was appeared as middle school students (33.7%) and followed by elementary school (30.6%), and high school (12.7%) students. Second, the SNA method was utilized for producing keyword frequency, degree centrality and network analyses. It was appeared that the most common keywords over six years included 'science gifted', 'gifted education', and 'creativity' and frequent keywords were science gifted, gifted education, gifted, creativity, science inquiry, perception, (creative) problem solving, science high school, scientific attitude, and STEAM. Third, through 2-mode network analysis, it was found that the research papers about cognitive characteristics were mainly related to perceptions, thinking ability, scientific argumentation, science inquiry and so on. It was also found that the research papers about social and emotional characteristics were related to correlation, motivation, creativity-character, self-efficiency and so on. It was concluded that the SNA method can be performed with literature analysis together for better understandings and interpretations of the research trend of science gifted education in-depth.

Students' perception on a science program for gifted was investigated. The whole program was designed in consistency and integrity based on the Autonomous Learner Model suggested by Betts & Kercher(1999). 7th, 8th and 9th grade students were enrolled in this program, offered by G Education Institute for Gifted(GEI) located in Seoul. A survey was done to ask students' perception regarding the effect of the program. The survey consisted of statements about the expected effects of the program and students were asked if they agreed with the statements. Most students strongly agreed that GEI's program has positive effects. Students replied that they learned useful and interesting science contents, enjoyed meaningful experience of cooperating with members in small groups, and were challenged by the inquiry tasks. They recognized that they were being trained to become autonomous learners. They also said that their choices and decisions were respected, which resulted in positive effects on their ability to negotiate or to inquire actively. These implies that Autonomous Learner Model had been successfully applied. Although it was not clear autonomy of students was fully grown, the possibility of becoming an autonomous learner was evident. Satisfaction level is higher for the older students, implying that the integrity in the program gave accumulating effect. Students response showed that three sub-programs of GEI, the classes of each subject, conference at the end of the year and autonomous learner training played equally important role for students to learn the process of scientific inquiry and autonomous learning. This was a positive sign that the strategies for scientific inquiry and autonomous learning were embedded and integrated deeply in the program. The results of current research suggests that the integrity of a program based on a specific education model for the gifted could provide better education environment for the gifted students.
