Radionuclide analysis methods must be secured in the event of emergencies such as the discovery of unknown nuclear material or nuclear accidents in neighboring countries or Korea. Most institutions in Korea are in their early stages of radionuclide analysis method development and do not even have Radiation Controlled Areas where they can handle the samples safely. Some institutions such as the Korea Atomic Energy Research Institute have the ability to perform radionuclide analysis for nuclear facilities or verification of nuclear activities. In Korea, it is necessary to secure nuclide analysis technology to enable independent verification in times of emergency or need. This paper analyzes uranium as the target nuclide using alpha spectrometer and TIMS. Alpha spectrometer detects alpha particles emitted from uranium samples and measures the concentration of uranium isotopes. This method has a high selectivity that distinguishes it from other elements, and accurate measurements can be made even when uranium samples are mixed with other elements. In addition, there is minimal interference from other radioactive isotopes in the sample, and the sample preparation is simple, resulting in relatively short analysis times. In contrast, TIMS detects ionized uranium ions by heating the uranium sample. This method may have potential interference from other elements and may take relatively longer analysis times. However, TIMS has high sensitivity and accuracy and can detect various elements other than uranium, making it suitable for various analyses. Therefore, when analyzing uranium, it is recommended to select and use the appropriate device according to the purpose, as both alpha spectrometer and TIMS have their pros and cons. Furthermore, by using both devices in parallel, more accurate and reliable results can be obtained. This paper aims to compare the analysis methods of alpha spectrometer and thermal ionization mass spectrometry, which are widely used for nuclide analysis in unknown nuclear materials.

As fashion has concentrated increasingly on inner values, it has become more directly connected with human life and society. This study analyzed anti-fashion, a movement that resists mainstream society and culture, which it views as causing inner conflicts such as competition, mammonism, consumerism, and egoism by fixating solely on the pursuit of growth and improvement. The study examined Kinfolk, an independent lifestyle magazine, to determine the essential values and principles that comprise this movement’s refusal of mainstream modern society. The analysis of Kinfolk identified the following characteristics of, the Kinfolk lifestyle: essentialism, nature-friendliness, retro sensibilities, socio-ethical awareness, and diversity. Essentialism refers to the pursuit of essence, brevity, innovation based on tradition and slow life. Nature-friendliness involves communion with nature and humanity, animal-friendliness, de-industrialization, de-urbanization, and nomadic behavior. The components of the retro sensibility include nostalgia, and interests in vintage culture, and handcrafts. Diversity encompasses commonplaceness, various subcultures, agelessness, genderlessness, acceptance of other cultures, and new understanding. The analysis identified the tendencies of anti-fashion in Kinfolk magazine as simplicity, naturalism, resistance to novelty, ethics, and inclusiveness. Anti-fashion pursues the essential values of human life that have been lost or forgotten in modern society. It is important to pay constant attention to the values of minority, non-mainstream and indie cultures that represent anti-fashion. It exerts considerable influence and has great potential as an area for the development of various style-based paradigms rather than as a single fashion direction.
