The recent expansion of large cities for economic benefits has worsened cultural inequalities within urban areas, eroding unique cultural identities and social values and deepening mistrust between regions. To tackle this, the idea of creating cultural cities is gaining traction, involving urban branding and cultural elements to foster balanced local cultural development. Current research primarily concentrates on case analysis in cultural cities, lacking sufficient studies examining the interplay of factors through empirical analysis, This study investigated whether Cultural City Formation Factors, which are resources of a cultural city, have a positive effect on City Brand Equity, City Innovativeness, Brand Personality, and Behavior Intention. For this study, questionnaires were collected from 310 people who continuously experience culture and arts in Seoul, and empirical analysis was conducted on 292 copies of them. Consequently, a significant impact was observed among the factors influencing cultural city formation, city brand equity, city innovativeness, brand personality, and behavioral intention. Moreover, it was verified that city brand equity, city innovativeness, and brand personality positively contributed to mediating effects as well as sequential mediating effects. It is expected that the results of this study will be used to establish the foundation for effective urban management and the development of strategies for creating cultural cities.

Social networking services (SNSs) serve to strengthen people's social relationships by providing ways for people to utilize such relationships especially like workplace. With the development of the internet worldwide, the number of SNS users is rapidly growing and a wider range of service types have become available. In this study, we designed a research model with a focus on what makes people use SNSs at workplace and how it is associated with changes in relationship quality and their intention to continue using the services and analyzed data collected for the research model. Theoretically, intrinsic and extrinsic motivation was invoked and measured, in terms of hedonic and utilitarian values, and satisfaction and trust were adopted as variables of relationship quality. Data were collected from Facebook users using workplace, and a partial least squares (PLS) analysis was made on 188 data points. The analysis results showed that two forms of motivation-hedonic and utilitarian-are separated from each other in their influence and that utilitarian value is more important than hedonic value, especially when it comes to users' satisfaction. In addition, the analysis found a weak relationship between satisfaction and trust in SNS environments; this was a little different from the results of previous studies.

국내 컨설팅산업이 성숙해지면서 컨설턴트에게는 고객의 비즈니스와 컨설팅 비즈니스에 대한 통찰력이 필수적으로 요구된다. 이러한 통찰력은 해당 비즈니스 도메인에 대한 깊은 이해와 고도의 역량을 필요로 하며, 날로 치열해지는 컨설팅 시장에서 지속적인 경쟁우위를 유지하기 위해 반드시 갖추어야 할 역량 요소로 평가된다. 본 연구는 소규모 컨설팅사에 소속되거나 개인적으로 활동하는 컨설턴트가 갖추어야 할 모든 요소를 담고 있는 ICMCI 역량모델을 국내 컨설턴트에게 적용해 보고자 하였으며, 설문조사로 수집된 데이터를 실증적으로 분석하였다. 연구결과, 비즈니스역량과 기술역량은 프로젝트성과에 긍정적인 영향을 미치는 것으로 나타났으나 가치 및 행동역량은 통계적으로 유의하지 않았다. 반면에, 사회관계역량에는 기술역량과 가치 및 행동역량만이 긍정적인 영향을 미치는 것으로 나타났다. 프로젝트성과와 사회관계역량에 미치는 역량의 요소와 영향의 크기가 정반대로 나타나 프로젝트성과가 우수한 컨설턴트는 사회관계를 소홀히 하고 프로젝트성과가 약한 컨설턴트는 사회관계에 더 집중한다는 의미로 해석된다. 본 연구를 통해 전문적인 컨설턴트로 성장하기 위해서는 컨설팅 비즈니스에 대한 깊은 이해와 지각이 필요하다는 것을 확인하였으나, 적은 표본으로 모집단의 특성을 충분히 반영하지 못해 연구결과를 일반화 하는데는 한계가 있다.

The purpose of this study is to develop and apply a make-a-thon program based on engineering problem solving for science high school students and to analyze the changes of participating students. Through the consultation of teachers and experts, a team-based and student-driven engineering problem-solving-oriented make-a-thon program was developed. And, the program operated using KAIST's human and material resources for 51 students. Students composed of 12 teams studied 12 topics through an engineering problem-solving process, and the overall program satisfaction was very high, on average 4.62. Through this program, students' creative leader competency have been positively changed, especially in cognitive characteristics (diffusion thinking, problem solving ability) and social characteristics (pursuit of social values). Attitudes toward engineering also changed positively, especially in terms of difficulty of engineering, interest in engineering, gender role in engineering, and engineering and occupational factors. In conclusion, it was confirmed that this program is very effective for science high school students with high demand for engineering education.

Receiving 100 citations from indexed journals is not a common occurrence, although it does happen very rarely, and it is even more uncommon for a non-indexed article. Given this, the purpose of this present study is to perform a bibliometric analysis of 100 cited Scopus articles to a non-Scopus indexed article, using a case study of the article titled "Authorship trends and collaboration pattern in the marine sciences literature: A scientometric study" which was published by Elango and Rajendran in the International Journal of Information Dissemination and Technology in 2012. On October 15, 2022, the Scopus database was searched with the article title in the references field, and the resulting bibliographic data was exported as a comma-separated values file. The tools utilized for this analysis were ScientoPy, the Bibliometrix R Package, and VOSviewer. Based on the findings, most of the cited articles were published within the last three years, and international researchers have given more recognition compared to Indian researchers. The most popular topics were found to be bibliometrics, bibliometric analysis, and bibliometrix. The fact that all 100 cited articles were published across various subject disciplines used by Scopus to categorise sources demonstrates how well-established the citing article is within the scientific community.

The development of Science and Technology and the social change require new paradigm in Education. In a traditional paradigm, learners have been regarded as a passive being and knowledge could be transmitted to learner. But within this paradigm, it is difficult to confront the social change and to develop problem solving skills in various context. This results in a new, alternative perspective, Constructive paradigm. As an alternative to the traditional settings, Constructive paradigm emphasizes the learner centered instruction. The reform movement in mathematics education including NCTM's standards revolves around this paradigm and the open education movement in our educational system is based on it. Open education values learner's interest, autonomy and internal motivation in learning. However, open education has been misunderstood by most of the teachers. It should be understood as the change of paradigm. In this study, as a way of helping students connect mathematics to their everyday lives and construct meaningful mathematical knowledge and concept, mathematical modelling is suggested. It consists of posing and specifying the real problem, formulation and constructing a mathematical model, analyzing and solving a mathematical problem. interpreting the solution and comparing with reality and communicating results. In this process, technology like computer can be a powerful tool. It can help students explore various problems more easily and concretely.

This paper provides two case studies of environmental impacts with socio-economic values. The first case is on flood protection levees conducted from 2003 to 2004 in Phu Tan district, An Giang province. The impacts were found by comparing full flood protection levees area (FFPL) to non-full flood protection levees area (NFFPL). Participatory Rural Appraisal (PRA) tools per each group of rich, middle, and poor people were used to list the impacts. Then, major impacts were selected by ranking and interviewing 60 households per site, and assessed by Cost Benefit Analysis (CBA) in rice production from 1996 to 2002 between two areas. The tested research indicated moving system of NFFPL to that of FFPL lost about 11 million VND/ha/year. The second case is on impacts of Penaeid shrimp farming conducted in Duyen Hai District, Tra Vinh Province in 2004-2005. Ninety households and 12 local officials were interviewed. Four PRAs were conducted and 36 water samples were taken inside and outside shrimp pond to measure values of DO, COD, Fe total, TSS, N-$NO_3{^-}$, N-$NH_4{^+}$, P-$PO{_4}^{3-}$, and Chlorophyll-a. Research results showed only 36.7% of the households got profit from shrimp farming. Highest financial efficiency was 0.72 for the semi-intensive system. Tested water indicators showed surface water quality did not match Vietnamese standard for surface water in coastal area (TCVN 5943-1995) and in rain. The water was very muddy and contaminated by organic aluminum. Summarily, the impacts were clarified more obviously via adding socio-economic values to assessment. Importantly, the values were transformed to household's income which is an indicator for policy-makers to consider the impacts obviously. Besides, data of different group of people impacted are cases contributing to consideration of the impacts in an appropriate social level.

중년여성들은 여성성의 상실과 함께 신체적, 정신적 변화를 겪게 되며, 자녀의 성장과 독립으로 돌봄과 양육의 역할이 감소되면서 심리적으로 공허함을 느끼기도 한다. 이 여성들은 자신의 역할감소에 따른 상실감과 공허함을 자신의 여가생활을 위해 자신의 가치관과 신념을 유지하는 계기로 이해하고 있다. 이에 중년여성들은 공예활동체험을 통하여 인간과 인간의 소통을 통한 사회적 관계에서 이루어지는 관계형성과 자아실현의 기회로 인식하여 우울감이나 공허한 마음과 같은 중년의 위기에 나타나는 부정적 감정을 극복하고 자아존중감과 사회적 지지를 확립하고 있다. 우리는 이 연구에서 공예활동의 체험요소가 중년여성의 자아존중감과 사회적 지지에 미치는 영향을 분석하기 위하여 공예활동의 체험요소를 독립변수로, 자아존중감과 사회적 지지를 종속변수로 하는 연구모형을 설정하였다. 연구결과 교육적 체험, 오락적 체험, 일탈적 체험은 자아존중감에 유의한 영향을 미치고 있으나 심미적 체험은 유의한 영향을 미치지 못하고 있다. 그리고 오락적 체험, 심미적 체험은 사회적 지지에 유의한 영향을 주지만 교육적 체험, 일탈적 체험에는 유의한 영향을 주지 못하였다. 따라서 중년여성의 감각과 감성의 변화에 영향을 줄 수 있는 체험공간의 환경적 특성인 미학적 요소와 시각적 요소를 살릴 수 있는 콘텐츠와 교류할 수 할 수 있는 출발에서 접근할 수 있도록 공예체험에 대하여 제도적으로 지원하는 방안이 제공되어야 한다. 그리고 공예활동으로 궁극적인 삶에 변화를 주는 요인을 고려하지 않은 한계가 있어 웰빙과 관련된 변수 등을 도출하여 새로운 모형을 제시할 것을 제안하고자 한다.
