The purpose of this study is to research on the professional development of pre-service chemistry teachers in terms of personal practical knowledge(PPK), and draw a discussion for pre-chemistry teacher education. A reflective discussion through a Community of Practice(CoP) activity has been conducted with 5 pre-service chemistry teachers studying in a college of education located in Seoul. The analysis of the results reveals that 'Subject-matter knowledge' is leaning toward massive chemical contents, 'Curriculum knowledge' is below the level of selecting, analyzing, and applying curriculum materials. 'Instruction knowledge', especially the knowledge of chemistry experiment and research, is not enough to lead secondary students' scientific experiment. 'Milieu of school knowledge' is stunted in growth for the reason of communication-deficiency between a college of education and a community, and among education- related groups. 'Self-knowledge' has been diminished not only because there is a bad influence from college classmates not wanting to be a teacher, but also a lack of communication in the chemistry-education department which can make pre-teachers' belief strong. In conclusion, it is especially needed for the chemistry-education department to strengthen pre-teachers' 'Self-knowledge' in order to develop PPK. This study suggests operating 'a professional community' that has a periodic meeting with pre-service teachers, teachers, professors, community people, education practitioners, and researchers. In addition, it would be effective for increasing pre-teachers' PPK to reconsider depth and direction of 'Subject-matter knowledge', to give an opportunity to examine curriculum materials critically and reorganize them, to improve the course of chemistry experimental subject to the way of improving pre-teachers' leadership in chemistry inquiry experiment, and to raise the quality of educational service activities.

This study analyzes the spatial characteristics of knowledge industry which has shown relatively rapid growth in the low-growth economy situation in recent years. In particular, we catch hold of the locational characteristics of the knowledge service industry which occupies the highest ratio by professional-expert jobs favoured by young generations, as well as estimate their occupational employment opportunities. By applying Location Quotient(LQ) and LISA, we reveal the spatial distribution patterns of publishing business, information service business and education service business in the Seoul Metropolitan area, and examine the changes in the spatial patterns during the last ten years. In order to understand the socio-economic factors which explain their locations, we apply the stepwise multiple regression analysis. Furthermore, we predict the changes distribution of Knowledge service industrial employment by applying Markov Chain Model. As the result, we found their clusters at the specific locations, while there is the significant variations in the socio-economic variables related their locations respectively. The related job opportunities of the knowledge service businesses in the Seoul Metropolitan area are predicted steady growth trend for the next four years, even though dull or stagnant trend is expected for other industries. This study provides basic resources to the planning for young generation employment problem.

PMO(Project Management Office) has been considered as a general approach for the successful operation of IT project. The previous studies tended to emphasize on the roles and functions of PMO in a normative way. However, in practice, since PMO is operated as a joint structure in which client firms and professional PMOs work together, it seems to be important that the implementation system of PMO should be properly formed. In this paper, it is examined whether the competence of client firms and professional PMO influence on the setup of implementation system of PMO, and also whether implementation system of PMO influence of the performance of IT project. In addition, it is also analyzed if the competence of client firms and professional PMO influence differently on the setup of implementation system of PMO, according to the degree of knowledge complementarity. As a result of this study, it is found that the competence of client firms and professional PMO influence positively on the setup of implementation system of PMO, and governance factors such as clear definition of organizational roles, responsibility, and setup of standardized processes are also important in performance of IT project. It is also shown that, if knowledge complementarity is formed with a common knowledge base between client firms and professional PMOs, Project Management Office functions effectively. In summary, for the successful performance of IT project, it seems that it is required to approach from the view point of governance in forming the implementation system of PMO and it is also important to form knowledge complementarity between client firms and professional PMOs.

When buoyant objects appear in contents, it is helpful in developing contents to express their attributes such as their length, width, weight, and velocity, and the magnitude and direction of regular waves dynamically. Therefore, we verify how the attributes of buoyant objects and the characteristics of waves cause the heaving motion of buoyant objects to change by using the equation of motion used in the naval architecture and ocean engineering. Our research results may help contents developers to develop contents with buoyant objects even if they do not understand the naval architecture and ocean engineering well. We show that we can calculate the motion of buoyant objects dynamically even if the velocity of buoyant objects or the characteristics of waves change dynamically. In the future, we will study how buoyant objects move on the irregular waves, and develop engines for buoyant objects on the real sea.

This study conducted a systematic review of mathematics teacher learning communities, especially the characteristics of teacher collaboration in community activities. Our review includes 14 research papers published in national academic journals indexed in KCI and 24 research papers in international academic journals indexed in SSCI from 2003 to 2019. Results show that the literature varied in research design, research topics, and patterns relating to teacher collaboration. While both international and national papers report teacher community activities concerning the organization, management, and participation, there were different levels of involvement, visions, and activities across the communities of practice. For example, research in national journals has presented teacher community as professional development while papers in international journals have focused on documenting teacher community becoming a reflective community of practice. This study contributes to understanding the interplay of context, conflicting epistemic culture, and professional agency in fostering collaboration in teacher communities. This paper also discusses relevant research methods to investigate mathematics teacher communities and insights into the policy and practice of mathematics teacher education.

약물 투여 후 약효의 출현은 흡수, 분포 등의 약동학적 단계(pharmacokinetic phase)를 거쳐 수용체 부위에서 약물과 수용체 사이의 약력학적(pharmacodynamic) 상호작용에 의해 나타난다. 따라서 약물요법 시 약효나 독성 발현의 큰 개인차는 약동학적 또는 약력학적 개인차에 의해 나타나며, 많은 약물에서 약효의 개인차는 흔히 약동학적 차이가 주역할을 함이 알려져 있고, 약물의 특성에 따라 약물의 대사 및 배설과 관련 있는 신장, 간장 및 심장 질환자에서는 현저한 약동학적 변화로 용법 조정이 필수적으로 요구되는 경우가 많다. 약동학적 개인차는 안전역이 좁은 약물에서 더욱 문제가 되며 이러한 약물의 적정 요법을 위해서는 수용체 부위와 평형을 이루고 있는 혈장약물농도를 적정 유지하는 것이 약동학적 개체차를 배제할 수 있는 한 방안이다. 근자에 이르러 체액내 약물 및 이의 대사물을 측정하는 분석 화학의 발전과, 임상 약물 동태학(clinical pharmacokinetics)의 도입 등으로 개개 환자에서의 적정 약물요법을 위한 TDM (Therapeutic Drug Monitoring)이 구미에서는 이미 보편화되어 있다 또한 국내에서도 이러한 새로운 의료분야의 연구 및 임상응용의 필요성이 점차 증가하고 있으므로, 이러한 시대적 요구에 발맞추어 본 지면을 통하여 임상약리학적 지식을 이용한 혈장 농도 데이터의 분석을 통하여 개개인에서의 적정 약물요법을 제시하는 TDM에 관하여 소개하고자 한다.

The purpose of this study is to examine the sanitation knowledge level in culinary employees for institutional food service and to examine influential relationship of their sanitation knowledge upon sanitation management performance, in order to qualitatively enhance sanitation and food safety in institutional food service. In addition, it was to examine the moderating effect of necessity, understanding, satisfaction, and application levels of sanitation education in the relationship between sanitation knowledge and sanitation management performance. 100 copies of questionnaire were widely distributed to 36 institutional food service centers(middle-high schools, universities, enterprises, and hospitals) in the Daegu Gyeongbuk areas. Among them, 361 copies were used for the final analysis. As a result, the sanitation knowledge of culinary employees was indicated to be the highest in individual sanitation knowledge. A significant relationship was shown between sanitation knowledge and sanitation management performance. Also, a positive moderating effect was indicated in the necessity of sanitation education considering individual sanitation knowledge and sanitation management performance. However, understanding, satisfaction, and application levels of sanitation education didn't show significant moderating effect. Nevertheless, four moderating variables show significant moderating effect in the influence of food storage knowledge, food handling knowledge and utensils and tools knowledge except for individual sanitation knowledge on sanitation management performance.

This study introduces strengths theory, a core subject of career development and job-getting, and discusses about the factors of strengths(namely talents, knowledge and skills), the processes of strengths personalization, and generating employability. It searches for opportunities to apply the concept of employability to the field of Library and Information Science now thrown under hard pressure from information and communication technology. Employability is defined here as competence to make oneself employable as needed by discovering or creating work opportunities using one's own tested personalized strengths. Employability is a package of systematically organized information about the essential abilities and productive personalities of a person, and it is essential to be duly cognitive of one's employability if one seriously intends to succeed in jobs and career. Since generation of employability heavily involves complex processes of information and knowledge-making, expertise from LIS, particularly from areas of personal information management(PIM) and personal knowledge management(PKM), is expected to help for process facilitation.

This research took an interpretive approach to investigate professional mathematicians' conception of mathematics, particularly focusing on their beliefs about the nature of mathematics as a discipline, and the relation between the discipline and themselves as knowers. The analysis shows that the professional mathematicians consider mathematics as human practice. For mathematicians, mathematics as a product is considered as a crystalization of practice that emerges in the dialogical relation between the discipline and its practitioners. This dialogical nature of mathematics suggests that professional mathematicians consider mathematics not as isolated fixed knowledge but as something they are playfully engaged with. The results of this research extend our understanding of what mathematics is and provide an alternative perspective on mathematics to make the learning of mathematics more accessible by dismantling the myth of the rationalist pure objectivity in mathematics.
