  • This study was performed in part with the task to find measures to improve the defining characteristics of feelings, value, interest, self-efficacy, and others aspects in regards to learning math among elementary and middle school students. For this study, it was essential to understand the appropriate questions that are needed to be asked during a consultation at a math clinic, for students that are having a hard time learning math. As a method for performing this study, the content of scheduled counseling over 2 years from a math clinic were collected and the questions that were given and taken were analyzed in order to figure out the types of questions needed in order to effectively examine students that are facing difficulty with learning math. The analysis was performed using Grounded theory analysis by Strauss & Corbin(1998) and went through the process of open coding, axial coding, and selective coding. For the paradigm in the categorical analysis stage, 'attitude towards learning math' was set as the casual condition, 'feelings towards learning math' was set as the contextual condition, 'confidence in one's ability to learn math' was set as the phenomenon, 'individual tendencies when learning math' was set as the intervening condition, 'self-management of learning math' was set as the action/interaction strategy, and 'method of learning' was set as the consequence. Through this, the questions that appeared during counseling were linked into categories and subcategories. Through this process, 81 concepts were deducted, which were grouped into 31 categories. I believe that this data can be used as grounded theory for standardization of consultation in clinics.

  • In recent years, Korean public libraries, placed under changing circumstances, require that some new and positive financial policies be formulated for the improvement of their services. T he purpose of this study is to propose a scheme to ensure the revenues of Korean public libraries. The main contents of this study are as follows : (1) Public finance theory is applied to the question of why the public library is publicly supported. The public library does not contribute to stabilization, but it does playa role in each of the other public sector functions : allocation of resources and redistribution of income. In public finance terms there is justification for at least partial subsidy of public library services, which have the attributes of public goods, merit goods and externalities. (2) Public libraries in Korea find themselves suffering from limited budgets. They are neglected in national and local budgets. The lack of adequate funding for library collections prevents libraries from rendering efficient services. (3) In order to put the finances of the Korean public library system on a firm basis, the following proposals are made: 1) It is proposed that the parallel administration under which public libraries are organized be unified to be directly under the local governments. 2) It is proposed that the legislative and administrative system for public library finance be strengthened. (1) Library expenses should be itemized independently in the calculation of general grants-in-aid to local governments. (2) A fixed portion of the total municipal revenue should be appropriated for public library services. It can be executed by making provisions expressly in the annual guidelines for budgeting, municipal ordinances, or in the Library Promotion Law. The rate of allocation should be specified as a part of the national public library development plan. (3) Library tax as a local tax can be imposed. An indirect tax is preferable in order to avoid public misunderstanding and antagonism. 3) The augmentation of the specific grants-in-aid for the public library is proposed. The Library Promotion Law and the Law on Budget and Administration of Grants should be amended to oblige the central government to give financial assistance to local public libraries. 4) It is proposed that strategies to encourage private endowments be worked out. Revision of the Law on Tax Reduction and Exemption and the activation of an advisory library committee at each public library are recommended. 5) Funding and utilization of the envisioned Library Promotion Foundation is proposed. Government contributions, contributions from the Culture and Arts Foundation, and donations from individuals, corporations, and enterprises can be considered as the financial resources of the Foundation. 6) It is proposed that the structure of the Korean Library Association be consolidated to exercise greater influence over the formation of national policy on the public library system. 7) It is proposed as an ultimate guarantee of the health of the public libraries that the citizenry be educated to strongly support library services in responce to the active services provided by the public libraries.

  • In this study, skin friction evaluation methods developed f3r deep foundation system were investigated and a method that can properly evaluate the skin friction of large size pneumatic caisson was proposed. Especially, based on Hong Won-Pyo's method, new technique (Kn parameter method) was suggested for estimation of the skin friction. The $\lambda$ method used widely to pile foundation was also investigated fur the applicability of estimation of the skin friction of large size pneumatic caisson. To do this, the data measured from the pneumatic caissons installed as a substructure of main tower in the suspension bridge part of Youngjong Grand Bridge were utilized. The data show that the skin friction is proportional to the rate of sinking, and the skin friction distribution with depth is similar to parabolic type rather straight line, which is a type generally observed in pile foundation. The skin frictions predicted by the Kn and $\lambda$ methods were plotted with the measured data for comparisons. It is cleary shown that the skin frictions estimated by the proposed Kn parameter method are well matched with the measured data. That is, for the large size pneumatic caisson having wide base, the new technique developed from Hong Won-Pyo's method is more suitable for estimation of the skin friction rather than the $\lambda$ method.

  • In this study, the characteristics of support behavior according to the change of ground condition of the cast-in-place pile and the large Caisson foundation, which are increasingly used as foundations of large structures and bridges. the allowable bearing capacity calculated using the yield load analysis method was analyzed to calculate similar allowable bearing capacity for each method. In addition, the allowable bearing capacity calculated by the ultimate load analysis method was found to have a large difference in bearing capacity for each method. Through this point, it can be usefully used as an empirical formula for evaluating the settlement characteristics of piles in future design and construction. In addition, as a result of examining the ground force distribution during sedimentation of large caissons, the section of the weathered rock layer showed almost constant ground force distribution as ground forces decreased after yield occurred at the base corner. And in the bed rock layer section, the foundation's center was transformed into a ground force in the form of a convex downward due to an increase in the ground resistance of the central part. Using these results, the theory previously presented by Fang (1991) and Kőgler (1936) was proved.

  • 19C was a chaotic time of Chosun dynasty, in order to make society stable, the scholas of Chosun wanted to define themselves as a little China on the east", to understand themselves as part of China and somehow they thought it will help for Koreans to understand who they really are. This "Chosun as a little China" idea is their spritual foundation and also the to understand who they are. From 16 C, Chosun had idea of "being a little China, so when Hwaseo talked about this idea, it was not new to the people and scholars in Chosun, however in Hwaseo's theory, the idea was more defined and realistic. In 19 C Chosun dynasty, the chaos caused by absece of fundimental principle was great, the scholars agreed Hwaseo's "Chosun as a little China" theory should be the foundational principle. Therefore, the problem of understanding and communicating about the west has to be reconcidered, because that was what they wanted to have as foundation before the comunication with west. Scholas of Chosun wanted to set their foundation before they often up their country to the west so they needed time to discuss this. In 19 C Japan on the other hand, they faced same chaos that Chosun experienced, however they went totally different way, because Japan unerstood the reallity and accepted western civilization. Specially, the latter period Mito study influenced to make that decision by changing the west from what they have to defeat to what they have to respect and copy. Both Chosun and Japan focused on making thier countries stronger, but Chosun found the answer in focusing on orthodox confucianism and Japan found the answer in making the military stronger. That is why these two countries went totally different ways in the history of 19-20 C North-east Asia.

  • As the economic, social, and environmental problems of the local community reach a serious level, our society is realizing the need to foster young talents who discover opportunities in local issues through entrepreneurship education and create social values through creative challenges. However, entrepreneurship education programs are generally focused on commerciality, so customized education programs to solve regional problems are insufficient. Therefore, this study aimed to develop a community problem-solving entrepreneurship curriculum. In this study, a competency based curriculum model was applied to develop the curriculum, and regional problem-solving entrepreneurship competencies were derived through expert advice from a total of 10 people. In the process, the Delphi methodology was additionally used to reduce the possibility of errors in the competency model. As a result of the study, a total of 23 regional problem-solving entrepreneurship competencies were confirmed, and knowledge(K) - skill(S) - attitude(A) by competency consisted of 5, 9, and 9, respectively. By applying this to Dunham's problem-solving six-step model, modular learning support measures were developed in the order of phase 1(problem discovery), phase 2(problem analysis), phase 3(plan), phase 4(measure), and phase 5(evaluation). This study is meaningful in that it integrated theory and practice by developing specific entrepreneurship curriculum and learning support measures based on the theoretical model devised in social welfare. In addition, it has implications in that it developed a regional problem-solving entrepreneurship competency model based on expert advice and proposed a specific curriculum based on this.

  • Bumblebees are widely used to pollinate crops in greenhouses and fields. Here we firstly developed an apparatus for the oviposition induction of the bumblebee Bombus ignitus using electricity. The apparatus consists of boxes for colony initiation, part of temperature control, part of heat transfer, and moving shelf. The result shows that the rates of oviposition and colony foundation in the newly developed apparatus are respectively 3.9% and 5.2% higher than in the existing apparatus using hot water. More importantly, the newly developed apparatus is 75% cheaper in costs and can more save energy than existing apparatus. These results indicate that the newly developed apparatus could serve as an effective apparatus for the oviposition induction of B. ignitus.

  • The purpose of this study is to make suggestions for the infectious disease surveillance systems as part of the government's healthcare policy intended to minimize damage by implementing an appropriate and swift crisis management in the event of future infectious disease outbreaks. To that end, this descriptive study analyzes the infectious disease outbreaks and the management and control thereof in Korea and other countries, so as to suggest some approaches to infectious disease surveillance systems applicable to affected regions. The analysis results shed light on the causes of the spread of future infectious diseases over the past years, and the management systems that could possibly deal with the trial and error in the response policy. It seems crucial to roll out appropriate information, training and promotion programs as part of the national disaster response systems to prevent infectious diseases in relation to the roles of multiple relevant government agencies in the event of disasters especially amid the COVID-19 pandemic.

  • Over-break, which is excavated larger than planned line at tunnel excavation, is inevitable due to the nature of blasting. But regarding the bottom of the foundation, most of the domestic ordering organizations pay only 10 cm thick filled concrete when pouring concrete due to over-break. In accordance, the construction cost will increase greatly if all the depths of the designed over-break are filled only with concrete. When tunnel excavation occurs, concrete filling of 18 MPa(T = 100 mm) and 150 mm~237 mm auxiliary concrete layer and 240 mm concrete track(TCL) are applied to the upper part. The concrete is installed in an excessive amount of about 600 mm between the lower part of the rail and the tunnel rock bed. Therefore, in this study, it is necessary to analyze the concrete crack structure according to the depth of the existing tunnel and the modified tunnel section, and to evaluate the adequacy of the required thickness of the tunnel floor concrete for securing the crack stability of the concrete.

  • Since western mathematics and astronomy had been introduced in Chosun dynasty in the 17th century, most of Chosun mathematicians studied Shu li jing yun(數理精蘊) for the western mathematics. In the last two decades of the 19th century, Chosun scholars have studied them which were introduced by Japanese text books and western missionaries. The former dealt mostly with elementary arithmetic and the latter established schools and taught mathematics. Lee Sang Seol(1870~1917) is well known in Korea as a Confucian scholar, government official, educator and foremost Korean independence movement activist in the 20th century. He was very eager to acquire western civilizations and studied them with the minister H. B. Hulbert(1863~1949). He wrote a mathematics book Su Ri(數理, 1898-1899) which has two parts. The first one deals with the linear part(線部) and geometry in Shu li jing yun and the second part with algebra. Using Su Ri, we investigate the process of transmission of western mathematics into Chosun in the century and show that Lee Sang Seol built a firm foundation for the study of algebra in Chosun.
