Purpose: In response to the surge in coronavirus disease 2019 (COVID-19) omicron variant cases, we have implemented preemptive testing for preschool and school. The purpose is to quickly detect COVID-19 cases using a rapid antigen test (RAT) kit so that normal school activities can continue. Methods: The results entered in The Healthcare Self-Test App were merged with the information on the status of confirmed cases in the COVID-19 Information Management System by Korea Disease Control and Prevention Agency (KDCA) for preschool and school of students and staffs March 2 to May 1, 2022 to analyze the RAT positive rate and positive predictive value of RAT. Results: In preschool and school 19,458,575 people were tested, weekly RAT positive rate ranged from 1.10% to 5.90%, positive predictive value of RAT ranged from 86.42% to 93.18%. By status, RAT positive rate ranged from 1.13% to 6.16% for students, 0.99% to 3.93% for staffs, positive predictive value of RAT ranged from 87.19% to 94.03% for students, 77.55% to 83.10% for staffs. RAT positive rate by symptoms ranged from 76.32% to 88.02% for those with symptoms and 0.34% to 1.11% for those without symptoms. As a result of preschool and school RAT, 943,342 confirmed cases were preemptively detected, before infection spread in preschool and school. Conclusions: RAT was well utilized to detect confirmed cases at an early stage, reducing the risk of transmission to minimize the educational gap in preschool and school. To compensate for the limitations of RAT, further research should continue to reevaluate the performance of RAT as new strains of viruses continue to emerge. We will have to come up with various ways to utilize it, such as performing periodic and repeated RAT and parallel polymerase chain reaction.

지난 20여년 동안 미국의 건강식품 시장은 건강한 사람들을 대상으로 연간 430억 달러에 이르는 시장으로 크게 성장했다. 지금까지 취급해온 건강식품은 대개 저 지방, 저 칼로리, 저 콜레스테롤 정도의 범주에 속하는 식품들이었다. 나이가 든 소비자들은 질병을 예방하거나 치료하는데 있어서 건강과 식품 사이의 연관성에 대해 그들이 알고 있는 지식을 바탕으로 건강을 유지하는 노력을 계속하고 있기 때문에, 다음 단계는 건강하지 못한 소비자들을 위한 식품시장으로 눈을 돌려야할때인 것이다. 즉, 건강상의 중대한 문제점들을 안고 있는 많은 어린이나 성인들을 대상으로 한 식품을 개발하는 것이다. 건강상의 문제는 이미 질병으로 진단되었거나 자가 치료를 해야할 단계등으로서 비교적 간단한 의료적 처치를 꾸준하게 오랫동안 실시해야만 하는 상태이다. 이 시장은 지난 10여년간 잠재성은 있었으나 아직 미개발 상태로 있었다.

1895년에 독일 뢴트겐에 의해 발견된 이후 X선은 1896년부터 의료목적으로 사용된 기록이 있으며, 한국에 도입되어 진단용X선발생장치로서 환자 진료에 사용하기 시작한 역사는 1911년경부터 조선총독부의원과 세브란스의원에 도입되어 사용하게 되었다. 최근 의학 및 의용공학의 발전으로 방사선을 이용한 진단 기술의 발전과 건강에 대한 국민의 의료욕구가 증가함에 따라 방사선을 이용한 질병의 진단과 치료 방법에서 새로운 기법이 개발되고 그 이용은 지속적으로 증가되고 있는 추세이다. 방사선의 이용은 진단 및 치료에 중대한 이득을 제공하고 있으나 그 이면에는 최적화 및 정당화 되지 않은 방사선의 피폭으로 장애 및 유해요인이 초래되는 것은 부인할 수 없다. 이와 관련하여 방사선을 이용하여 검사 및 치료를 시행함에 있어 피폭선량 최적화를 위한 기술적 노력은 방사선 관계자의 막중한 의무이다.

The purpose of this study was to examine relationships among disease-related characteristics, symptom stress, quality of life in women with endometriosis, and then to identify predictors of quality of life in them. The self-reported questionnaires were administered to 99 women in one general hospital. As results of multiple regression analysis, the factors affecting quality of life in women with endometriosis were sick leave (${\beta}=-.27$, p=.000) and symptom stress (${\beta}=.59$, p=.000), explained women's quality of life with 57.0% (F=11.39, p<.001). Based on the findings, there is a need to develop a self-care program for chronic pain and a nursing intervention for enhancing a quality of life in women with endometriosis.

Purpose: This study was conducted to better understand the illness experiences and palliative care needs in community-dwelling persons with cardiometabolic diseases. Methods: This qualitative descriptive study was conducted with 11 patients (and three family members) among 28 patients contacted. Interviews were led by the principal investigator in her office or at participants' home depending on their preference. All interviews were digitally recorded and transcribed by a research assistant. The interviews were analyzed by two independent researchers using a conventional method. Results: Participants' ages ranged from 42 to 82 years (nine men and two women). Three themes were identified: (1) same disease, but different illness experiences; (2) I am in charge of my disease(s); (3) preparation for disease progression. Participants were informed of the name of their disease when they were diagnosed, but not provided with explanation of the diagnosis or meant or how to do self-care to delay the disease progression, which increased the feelings of uncertainty, hopelessness and anxiety. Taking medication was considered to be the primary treatment option and self-care a supplemental one. Advanced care plans were considered when they felt the progression of their disease(s) while refraining from sharing it with their family or health care professionals to save their concerns. All participants were willing to withhold life-sustaining treatment without making any preparation in writing. Conclusion: Education on self-care and advanced care planning should be provided to community-dwelling persons with cardiometabolic diseases. A patient-centered education program needs to be developed for this population.

To investigate the factors influencing workers' perception and attitude toward special periodic health screening test for workers, a survey with self-administered questionnaires was performed on 779 workers who had special periodic health screening test from September 1 to October 15, 1994. A study model was developed by modifying the health belief model. The end and intermediate response variables of the model were the voluntary participation and necessity perception on the special screening for workers. The result of analysis was consistent with the study model. Rates for the necessity perception and voluntary participation on the special screening for workers were 77.2%, 79.2%, respectively. Factors influencing on the voluntary participation were necessity perception, benefit of special screening for workers, and cue to action. And on the necessity perception were susceptibility and severity to occupational disease, knowledge to special screening for workers, and support of company. General and occupational characteristics influencing on the susceptibility and severity to occupational disease were sex, age, educational level, work duration, and health education. On the knowledge to special screening for workers were age, educational level, work duration, and locus-of-control. On the benefit of special screening for workers were age, locus-of-control, pride on health, and health education. Therefore, to increase the voluntary participation and necessity perception on the special periodic health screening for workers, 1) if a worker is judged as occupational disease, the judgment should be widely known in his workplace, 2) the screening result forms should be directly sent to the workers themselves, 3) for the positivity of employers, the campaign and education program subjected to them should be planned, 4) health education should give the first consideration to the younger, lower educational level, and newly employed women, and its frequency should be increased and it should be more frequently dealt with occupation-related subjects, and 5) the employers should have a careful concern in not being disadvantageous to workers due to result of screening.

NMR spectroscopy enables us to measure the molar concentration of the metabolites in the organisms, and this technique is the only method to measure the concentration non-invasively. The proton NMR spectroscopy has been used to study the biochemical changes in human as well as in animal brain. MRI uses the proton densities and its relaxation times for reconstructing images, but MRS gives the biochemical changes inside the body. NMR spectroscopy could provide the information which MRI and CT could not, and this makes NMR spectroscopy more useful in diagnosing diseases. This study was tried to develop the quantitation of the molar concentration of the metabolites in the brain using the proton MR spectroscopy. The spectra of each metabolites was obtained, and the proton MR spectra was obtained from the insula gray matter areas of the 16 volunteers. And this spectra was analyzed to estimated the molar concentrations of the metabolites in the region. The results showed the very similar to those of the others.
