Internal dosimetry is a discipline which brings together a set of knowledge, tools and procedures for calculating the dose received after incorporation of radionuclides into the body. Several steps are necessary to calculate the committed effective dose (CED) for workers or members of the public. Each step uses the best available knowledge in the field of radionuclide biokinetics, energy deposition in organs and tissues, the efficiency of radiation to cause a stochastic effect, or in the contributions of individual organs and tissues to overall detriment from radiation. In all these fields, knowledge is abundant and supported by many works initiated several decades ago. That makes the CED a very robust quantity, representing exposure for reference persons in reference situation of exposure and to be used for optimization and assessment of compliance with dose limits. However, the CED suffers from certain limitations, accepted by the International Commission on Radiological Protection (ICRP) for reasons of simplification. Some of its limitations deserve to be overcome and the ICRP is continuously working on this. Beyond the efforts to make the CED an even more reliable and precise tool, there is an increasing demand for personalized dosimetry, particularly in the medical field. To respond to this demand, currently available tools in dosimetry can be adjusted. However, this would require coupling these efforts with a better assessment of the individual risk, which would then have to consider the physiology of the persons concerned but also their lifestyle and medical history. Dosimetry and risk assessment are closely linked and can only be developed in parallel. This paper presents the state of the art of internal dosimetry knowledge and the limitations to be overcome both to make the CED more precise and to develop other dosimetric quantities, which would make it possible to better approximate the individual dose.

Scant attention has been given to analyzing how knowledge sourcing strategies affect firm performance in SMEs and what are the differences between SMEs and large firms in the patterns of knowledge sourcing strategies adoption. This study attempts to advance the current literature by examining the impact of knowledge sourcing strategies on SMEs performance. The empirical segment of our work is based on data on knowledge sourcing strategies of SMEs and organizational performance from a sample of 166 Korean firms. Our results indicate knowledge sourcing adoption patterns of SMEs are different from large firms. In addition, the results confirm that substitutability between internal- and external-oriented, person- and external-oriented sourcing strategies. This study sheds new light on knowledge management (KM) research by identifying the relationship between knowledge sourcing strategies and SMEs performance.

Multinational Corporations (MNCs) are establishing globally-distributed R&D centers around the world. Firms can overcome resource constraints and achieve superior innovative performance not only by using internal resources but also acquiring knowledge from oversea R&D centers. This paper explores the key factors that have been cited as significant influences on the ability to transfer knowledge, an important area of knowledge management of MNCs. Also, we identify the emerging outcomes in terms of R&D transfer and for the education, employment, and retention of knowledge works in MNCs. The result will be helpful for both MNC's managers and governments' decision makers with respect to R&D centers.

Knowledge and technology resources are the most crucial sources for the achievement of sustainable development in competitive advantage. Meanwhile, few empirical studies have clarified the types of knowledge and technology resources that nonprofit organizations (NPOs) use and develop. This study aims to categorize knowledge and technology resources in NPOs that both researchers and practitioners can use to develop the nonprofit sector further. A qualitative research method was used for the study. Data were collected from 31 interviews with senior and founding members of NPOs in Thailand. Analysis of qualitative data identified five critical categories of knowledge resources: human resources, organizational practices, partnership or stakeholder involvement, operational practices, and other resources. This study also illustrates both internal and external technology resources, which are used in sample organizations. The study's findings contribute to developing a body of knowledge management literature related to the knowledge and technology resources of NPOs.

The purpose of this study was to investigate the internal factors whether teachers execute experiments at the science classes in the elementary school. Semi-structured in-depth interviews were performed with 9 elementary school teachers who have served for more than three years. In-depth interviews were performed individually and all the interviews were recorded. Data sources were analyzed by grounded theory. The results were as follows: The internal factors that they did experiments at the science classes were science teaching faiths in experiment, self confidence in experiment, interest in science. and the internal factors that they did not experiment at the science classes were lack of science content knowledge, lack of science education knowledge, memory of failure at experiment, and so on. The investigation results imply inquiry activities should be more strengthened in elementary teacher education program and pre-service teacher curriculum. And it needs to give a materials of receiving information and guidance detailed about the experiments.

Objective: The purpose of this study was to provide data for the development of Korean medicine (KM) clinical practice guidelines (CPG) for gastric cancer (GC) by identifying the awareness and knowledge needs of KM doctors (KMD) through an online survey. Methods: A survey questionnaire was produced by referring to the previous recognition survey studies for clinical KMDs. The survey questionnaire was composed of questions regarding the current status of clinical care for GC, the knowledge level of clinicians about GC, and other details that clinicians use during practice. The survey was conducted from September 20 to October 22, 2021. An online survey was conducted with 195 KMDs from the Society of Korean Medicine and the Korean Association of Traditional Oncology of KM. Results: A total of 195 respondents participated in the online survey regarding the current status of GC treatment. Of this number, 10.3% of the respondents specialize in GC, but even if they do not currently specialize in GC, they are more likely to treat patients with GC in the future. In terms of the specifics of KM treatment, there was a demand for information on comprehensive KM treatment methods, such as herbal medicine, acupuncture, moxibustion, cupping, and chuna, as well as on analyzing the effectiveness of combined treatment with chemotherapy and radiation. Conclusion: In this study, we were able to understand the clinical KMDs' perception of GC, knowledge level, and requirements in the CPG. The results of this study will provide the basic data for the development of CPG for GC.
