The purpose of this study is to identify the value of global citizenship and cooperative learning, and one of the effective ways to educate citizens around the world is to present a Co-op Co-op model for cooperation, which can be used in social studies class in secondary schools. While the need and importance of global citizenship education is emerging as a way to respond to the rapid globalization, there is still a lack of research on the teaching programs available at secondary schools. Therefore, through theoretical discussions, this paper identified diversity, cooperation with others, respect for democratic processes, active participation, and responsibility for global issues as key values of global citizenship. Based on this, class programs were developed and presented based on the first unit of social studies in secondary school 『Human rights and constitutional』 unit using Co-op Co-op among various cooperative learning models. The contents to be modified and supplemented by asking a group of experts from current teachers to review the program to ensure the validity and reliability of the class program developed in this study.

The purpose of this study was to develop instructional programs aimed at enhancing middle school students' understanding of evolutionary concepts using a step-by-step writing strategies and an applicable evaluation rubric for evolutionary concepts. To achieve this, a step-by-step writing instructional model (PEECE) was devised as a method for scientific writing, and essential evolutionary core concepts were selected considering the middle school curriculum's coverage of biological evolution. Six evolutionary core concepts-variation, inheritance of variation, differential survival and reproduction, microevolution, and macroevolution-were chosen, with each serving as the focus of a lesson in a four-lesson program following the PEECE lesson model. The program was implemented with 16 students in a co-curricular middle school class. Pre- and post-lesson evolutionary concept checklists were administered to diagnose and compare the level of evolutionary concept understanding. Additionally, students' writing materials for each evolutionary core concept were collected, scored using an evolutionary concept evaluation rubric, and thoroughly analyzed. The results indicated that the step-by-step writing strategy effectively enhanced understanding of the six evolutionary core concepts and reduced cognitive biases and misconceptions about evolution. Contrasted with the optional evolution concept test, the descriptive writing activity provided a more tangible insight into students' scientific concepts, biases, and misconceptions, facilitating teachers' assessment of understanding and feedback provision. Moreover, the jointly developed evaluation rubric offered specific scoring criteria, enabling objective assessment without subjective influence, allowing analysis and scoring of students' writing materials across evaluation areas for collecting fundamental data.

This study aimed to examine the impact of grit and problem-solving skills on clinical competency among fourth-year nursing students who had experienced clinical practice. This descriptive survey research was conducted from March 1, 2024, to March 31, 2024. The collected data were analyzed using the SPSS/WIN 24.0 statistical program. Out of a total of 130 respondents, 124 participated, yielding a response rate of 95.4%. The results showed that grit scored 3.11, problem-solving skills scored 3.07, and clinical competency scored 3.27. There were significant positive correlations between grit and problem-solving skills (r=.510, p<.01), clinical competency and problem-solving skills (r=.381, p<.01), and clinical competency and grit (r=.522, p<.01). Factors influencing clinical competency included grade point average (𝛽=.240, p=.002), motivation for further study (𝛽=-.149, p=.041), satisfaction with clinical practice (𝛽=-.199, p=.011), and grit (𝛽=.329, p<.001), with these factors explaining 24.4% of the variance. Therefore, based on the findings of this study, it is necessary to develop tailored educational programs considering various characteristics to enhance students' grit within the nursing curriculum.

Individuals gather information online to resolve problems in their daily lives and make various decisions about the purchase of products or services. With the revolutionary development of information technology, Web 2.0 has allowed more people to easily generate and use online reviews such that the volume of information is rapidly increasing, and the usefulness and significance of analyzing the unstructured data have also increased. This paper presents an analysis on the lexical features of expert product reviews to determine their influence on consumers' purchasing decisions. The focus was on how unstructured data can be organized and used in diverse contexts through text mining. In addition, diverse lexical features of expert reviews of contents provided by a third-party review site were extracted and defined. Expert reviews are defined as evaluations by people who have expert knowledge about specific products or services in newspapers or magazines; this type of review is also called a critic review. Consumers who purchased products before the widespread use of the Internet were able to access expert reviews through newspapers or magazines; thus, they were not able to access many of them. Recently, however, major media also now provide online services so that people can more easily and affordably access expert reviews compared to the past. The reason why diverse reviews from experts in several fields are important is that there is an information asymmetry where some information is not shared among consumers and sellers. The information asymmetry can be resolved with information provided by third parties with expertise to consumers. Then, consumers can read expert reviews and make purchasing decisions by considering the abundant information on products or services. Therefore, expert reviews play an important role in consumers' purchasing decisions and the performance of companies across diverse industries. If the influence of qualitative data such as reviews or assessment after the purchase of products can be separately identified from the quantitative data resources, such as the actual quality of products or price, it is possible to identify which aspects of product reviews hamper or promote product sales. Previous studies have focused on the characteristics of the experts themselves, such as the expertise and credibility of sources regarding expert reviews; however, these studies did not suggest the influence of the linguistic features of experts' product reviews on consumers' overall evaluation. However, this study focused on experts' recommendations and evaluations to reveal the lexical features of expert reviews and whether such features influence consumers' overall evaluations and purchasing decisions. Real expert product reviews were analyzed based on the suggested methodology, and five lexical features of expert reviews were ultimately determined. Specifically, the "review depth" (i.e., degree of detail of the expert's product analysis), and "lack of assurance" (i.e., degree of confidence that the expert has in the evaluation) have statistically significant effects on consumers' product evaluations. In contrast, the "positive polarity" (i.e., the degree of positivity of an expert's evaluations) has an insignificant effect, while the "negative polarity" (i.e., the degree of negativity of an expert's evaluations) has a significant negative effect on consumers' product evaluations. Finally, the "social orientation" (i.e., the degree of how many social expressions experts include in their reviews) does not have a significant effect on consumers' product evaluations. In summary, the lexical properties of the product reviews were defined according to each relevant factor. Then, the influence of each linguistic factor of expert reviews on the consumers' final evaluations was tested. In addition, a test was performed on whether each linguistic factor influencing consumers' product evaluations differs depending on the lexical features. The results of these analyses should provide guidelines on how individuals process massive volumes of unstructured data depending on lexical features in various contexts and how companies can use this mechanism from their perspective. This paper provides several theoretical and practical contributions, such as the proposal of a new methodology and its application to real data.

Kim, Yong-Hwan is a one of the South Korean major cartoonists between 1940s and 1960s. Kim, Yong-Hwan drew a variety of genres from children's cartoon to current-affair cartoon. Furthermore, Kim, Yong-Hwan took the lead in publishing cartoon magazine and newspaper after the Independence, and has been highly appreciated as a pioneer of Korean cartoon. Kim, Yong-Hwan created many works in the fields of illustrations, Oriental painting, history painting, caricature, etc. After going study for painting to Japan, Kim, Yong-Hwan made his debut as an illustrator called Kita Koji in Japan. However, not much is known about his works in Japan, only there is a simple data about his Japan period and some pieces of illustration during Japan years. In this paper, I examined in detail about Kim, Yong-Hwan's work activity in Japan which has been little known in Korea for a long time. I studied on illustrations in magazines and books which he drew in the name of Kita Koji, on the basis of the data of the National Diet Library of Japan. I could know that Kim, Yong-Hwan worked actively in a diversity of publishers and magazines. In addition, I could realize that many magazines in which Kim, Yong-Hwan drew illustrations were very popular ones. This demonstrates that Kim, Yong-Hwan was much recognized in Japan for his talent. However, a large number of Kim, Yong-Hwan's illustrations were published from late 1930s to mid-1940s. This period was the years that Japan concentrated all her energy for World War II. All the publishing were severely censored during this period. A majority of publishing in this period supported Japanese militarism, and glorified Japan's war policy. Kim, Yong-Hwan's illustrations were no exception, too. It was really sorry about his activity during his Japan period. This essay means a lot to a field of cartoon studies in terms of a collection of materials during Kim, Yong-Hwan's Japan period. Besides, I think that henceforth, this paper can contribute to a follow-up study on Kim, Yong-Hwan' work and his broad background.

Objectives: The purpose of this study was to investigate the level of health promoting behaviors and the significant factors in rural elderly(young-old vs old-old). Methods: The data was collected using structured questionnaires from June 22th to Sep. 18th, 2009. A total of 556 elderly aged 65 years or over were selected from 14 rural districts in C province, South Korea. Age was divided into two groups as below 65-74 and 75 or older. A structured questionnaire was used to obtain information on the demographic characteristics, their perceived health status, the difficulty of activities of daily living, quality of life, self-efficacy and health promoting behaviors. The health promoting behaviors included nutrition, stress management, interpersonal support, exercise, health responsibility and self-actualization. The scores for health promoting behaviors were used mean and standard deviation. The data was analyzed using SPSS Win 12.0. Results: Of the 556 subjects, we found that the young-old(65-74 aged) were 359 and the old-old elderly(over 75 aged) were 197. We found that the level of health promoting behavior was higher for young-old ($2.75{\pm}0.374$) compared to old-old elderly people ($2.67{\pm}0.399$). In multiple linear regression, quality of life, self-efficacy, living with spouse, and number of generation living together for the young-old, and quality of life for old-old elderly were significantly associated with health promoting behaviors. Conclusions: The study findings indicate that there are age differences in associated factor of health promoting behaviors. Therefore our findings may provide useful assistance in developing effective intervention programs to improve health promoting behavior of the elderly in rural areas according to their age differences.

Objective : The purpose of this study was to investigate establishment status of the mandatory courses designated by Ministry of Health & Welfare for qualification of sensory developmental rehabilitation specialist(SDRS), within curriculum of baccalaureate occupational therapy(BOT) programs in Korea Methods : This is a narrative study to investigate and analyze certain courses established in curriculums of all 4-years occupational therapy(OT) programs, which is 32 schools. Results : 1) The shared mandatory subject, 'Understanding Children with Disabilities(UDC)', has been established at 9 schools. For the branch mandatory subjects, 'Neuroscience(NS) or Neuroanatomy' has been established at all 32 schools, 'Sensory Processing Dysfunctions and Intervention(SPDI)' or 'Sensory Integration' has been established at 31 schools, and each of 'Assessment & Evaluation for Children(AEC)' and 'Practicum of Sensory Rehabilitation(PSR)' has been established 7 schools for same. 2) For the mandatory courses, all 32 schools were offering designated- and alternative courses of NS, SPDI, AEC, but there was no change in the number of schools offering the practicum course since there was no case of alterative for it. 3) In terms of general provision score, there were 4 schools for score 7, 4 schools for score 6, 2 schools for score 5, 1 schools for score 4, 2 schools for score 3, and 19 schools for score 2. Conclusion : Establishment of the mandatory courses required to the qualification of SDRS among the BOT programs in nation were investigated. Including alternative courses, all the branch mandatory courses except practicum course are established in all the 32 schools. However, the shared mandatory subject, UDC and the practicum subject were established in only few schools. In the provision level evaluation of BOT programs for the SDRS qualification, it is shown that many schools has been started the provision already but still many schools' curriculum did not reflect the willingness and accuracy well. For the schools planning successful accreditation in near future, it is recommended that they prioritize the establishment of the shared mandatory course and the practicum course since these two subjects are recognized as critical factors for that. In addition, it is also needed of comparative inspections for course title and syllabi based on the guideline provided by Ministry of Health & Welfare.

In this research, the preparation processes for making a series of $\omega$-mercapto alkylamine 1 and $\omega$-mercapto alkanoic acid 2 useful for studying of the self-assembled monolayer(SAM) are described. The preparation methods of the first goal materials, $\omega$-mercapto alkylamines 1 were carried out as follows: First, $\omega$-phthalimide alkanol 3 was synthesized from commercially available potassium phthalimide derivatives and $\omega$-bromoalkanol in DMF at $80{^{\circ}C}$ via substitution reaction. After refluxing $\omega$-phthalimide alkanol 3 with hydrazine hydrate in ethanol followed by treating with c-HCl, $\omega$-aminoalkanol 4 was obtained in 76-98% yield, accompanied with side-product 5. Bromination of hydroxyl moiety of $\omega$-aminoalkanol 4 using aqueous hydrobromic acid furnished $\omega$-bromoamine 6 in 34-97% yields. Substitution reaction 6 with thiourea in 95% ethanol gave $\omega$-aminoalkanthiuronium 7, which was treated with aqueous strong base and aqueous strong sulfuric acid gave desired products, $\omega$-mercapto alkylamines 1 through overall 5 steps. The second target material, $\omega$-mercapto alkanoic acid 2 was prepared via 2 steps. $\omega$-bromo alkanoic acid was reacted with thiourea to give $\omega$-thiourea alkanoic acid 7 in 69-85%, which was treated with aqueous strong base and strong acid to furnish $\omega$-mercapto alkanoic acid 2 in 50-98%. The fabricated long-chain alkylthiol(LCAT) can be used as linkers to immobilize protein, enzyme and various kinds of biomolecules on the surface of metallic materials(Au, Pt, Ti) by SAM, and can be useful chemical tools for the application study on the surface modification of metallic materials.

The Seoul metropolitan government announced an open design competition for reconfiguring the annex building of the National Tax Service Building site on Sejong-daero as a space for citizens to commemorate the 70th anniversary of Korea's liberation. The site, built during the Japanese colonial period, has been in use ever since. This study, as one of the entries for the competition, described the strategy and design contents by drawing the concept and main points of the design through an analysis of the historical context of the site. As the guidelines instructed to consider the value of the Sejong-daero area and the cultural heritage through a comprehensive analysis, this study specified the site as a place connecting the past, present and future. Since the foundation of the Joseon dynasty, the Korean Empire and the Japanese colonial period, Sejong-daero has been a main site for important events and activities along with the change of the city structure. Jungdong, to the rear of the site, was a place for adopting new culture during the beginnings of modern Korea, while adjacent places like Duksugung, the Anglican church, and the Seoul City Council building have also been historic urban landscapes of the historical layers of time as the city has changed. When Gojong announced the Korean Empire, the city structure was remodeled with this site as the center along with Sogong-ro, Wongudan and so forth. In this study, public interest stated in the guidelines was focused and the relevance of the road and the plaza was considered from the view of an historic urban landscape by a comprehensive analysis with Sejong-daero as the center. The restoration of public interest was to be drawn as the concept of the object site by considering the current status and the change around the site and Jungdong at the rear. Returning the site to the public is ambiguous with the relevance of the restoration of public interest and as the symbol of the idea of the Korean Empire by Gojong's announcement. The object site, having the characteristic of being returned to the public, must ensure public interest and therefore the design strategy has been established with the keywords of openness, connection and void. As a result of a review of the alternatives, a plan for a square has an 8% slope, just as the original site does, and provides ramps for convenient access for all, including the disabled and the elderly, and is connected to the grounds adjacent. No construction is allowed at the terrace square of the Anglican church level and the main square connected to the pedestrian street, so a variety of modern city utilization can be done. The value of the site at which this design is aimed shall be given back to the public with the concepts of modern democracy, independence, and the vision of Gojong by reinterpreting the space from a modern viewpoint. This study focused on the processes of establishing a main concept and strategy rather than the content of the design details, and the suggestion is meaningful in that the design for the object site with historic backgrounds and the layers of time can continue to be grown.
