The purpose of this study was to identify the factors influencing the level of nursing needs of a long-term care service user at home and the care giving burden of a primary caregiver. For this study, data were collected from 152 primary caregivers in J City with self-administered questionnaires and analyzed using multiple regression technique. Among the nursing needs of long-term care giving service users, the level of psychological and social requests was the highest. This study found that two characteristics variables(long-term care insurance benefit level and long-term care giving grade) had difference was statistically significant in physical nursing needs and psychological nursing needs. Out of care giving burden of primary caregivers, physical care giving burden was found to be the highest. Out of factors influencing care giving burden, daily care giving hours was the factor which had strongest influence. Basic living recipients and female primary caregivers showed higher care giving burden. The more care givers there were, the less care giving burden became.

In this study, ultraviolet protection factor (Sun Protection Factor, SPF) was investigated to provide basic data for subject safety and research of ultraviolet (UV) irradiation test in the future. Trial subjects (395 people) of skin type I, II, and III were evaluated according to skin type standard table. After measuring the skin color using a colorimeter, ITA (Individual Typology Angle) value was calculated. Subjects with 28 and above ITA value were positioned comfortably to be UV irradiated for 60 s and erythema was evaluated 24 hours after application. MED (Minimal Erythema Dose) was investigated where the minimal amount of erythema existed among UVB irradiated area. Statistical analysis was investigated using Statistical Package the Social Sciences program. As a result, the darker skin color results in the higher MED value since the higher skin type number results increased MED value and female has higher MED value than male since female has darker skin type than male. There was no relation between MED difference by ages in all different ages. However, it is hard to draw a conclusion as above since the number of subjects were not sufficient to support statistical significance for MED values by different ages. However, MED values by skin types obtained through this study can be used as a standard when MED value is expected to evaluate efficacy of sunscreen product and as basic data for further safety of clinical researches.

최근 노인인구의 증가와 함께 식생활의 변화에 의해 사망원인의 변화가 일어나고 있다 한국인의 주요 사망원인 중 뇌혈관 및 심장질환 등 순환기계 질환에 의한 사망이 증가하고 있는 추세이며, 심장순환계 질환의 위험요인인 고혈압의 이환률도 65세 이상 노인에게서 증가하고 있다. 고혈압은 만성질환으로 산화적 스트레스를 증가시키는 질환이므로 본 연구에서는 건강한 노인과 고혈압 노인의 체내 항산화 영양상태를 비교하기 위해 울산지역 50세 이상 노인을 대상으로 하였다. 대조군은 질환이 없거나 골다공증, 위장질환과 같은 기타 질환을 가진 사람 96명이었으며, 고혈압환자군은 고혈압을 가진 모든 질환자 118명이었고, 항산화 영양소 섭취나 혈장내 항산화 영양상태에 영향을 미치는 성별, 연령, 흡연 및 음주상태를 보정하여 비교하였다. 고혈압환자의 평균 유병기간은 6.1년이었으며, 항산화 비타민 섭취량은 비타민 A, retinol, $\beta$-carotene과 비타민 C 섭취량 모두 고혈압 유무에 따른 유의적인 차이가 나타나지 않았으나 고혈압환자의 섭취량이 높은 경향을 보였다. 한국인영양권장량과 비교한 결과 대조군의 비타민 A 섭취는 권장량의 86.2%, 고혈압환자군은 권장량의 103.0%를 섭취하여 고혈압군에서 유의적으로 높았고, 권장량의 75% 이하 섭취자의 비율은 대조군에서 46.9%, 고혈압군에서 41.5%로 조사되었다. 비타민 C 섭취는 대조군에서 권장량의 176.6%, 고혈압군에서는 189.0%로 나타나 질환의 유무에 관계없이 두 군 모두 권장량의 170%이상을 섭취하고 있었으나 권장량의 75% 이하를 섭취하는 사람의 비율이 대조군에서 13.5%, 고혈압군에서 17.0%로 고혈압군에서 높게 나타났다. 혈장 비타민 C의 농도는 대조군 15.3 mg/L, 고혈압환자 15.9mg/L, 혈장 $\beta$-carotene 농도는 대조군 0.21mg/L, 고혈압환자 0.22 mg/L로 나타나 고혈압 유무에 따른 차이가 없었고, 혈장 비타민 A,E 농도 및 총 항산화능력은 대조군에 비해 고혈압환자에게서 유의적으로 높게 나타났다. 또한 혈장 지질과산화물의 농도도 유의적이지는 않지만 고혈압환자에게서 높은 경향이 나타났다. 따라서 고혈압에 따른 항산화 영양상태를 비교한 결과 전반적인 항산화 비타민의 섭취량, 혈중 비타민 농도 및 총 항산화능력이 예상과 달리 대조군 보다 고혈압환자에게서 유의적으로 높게 나타났다. 이런 결과는 질환자들이 자신이 가진 질병의 진전을 막거나 치료의 목적으로 치료제를 복용하고, 식이요법을 실시하고 있기 때문으로 사료되며, 고혈압과 같이 산화적 스트레스가 증가하는 질환의 경우 체내 항산화 체계 반응이 이러한 변화에 효율적으로 대처하기 위한 방향으로 증가되었을 가능성이 있을 것으로 사료된다. 특히, 본 연구의 대상자들의 유병기간이 6.1년으로 비교적 길기 때문에 질환의 진행정도에 따른 항산화 상태를 측정하거나 비교적 질환으로 판정된 직후의 사람들의 대상으로 한 연구 등 더 많은 연구가 필요하다.

In the context of the global pandemic caused by COVID-19, emergency alert text messages can violate the privacy of confirmed corona positive cases. This study used conjoint analysis to identify the essential information factors and the privacy invasion information factors of local government initiated safety notices. As a result of this study, we found eight essential information factors, including all routes of the confirmed case and ten privacy invasion factors of safety notices. In addition, we found that there is a similarity between the combinations of information perceived to be the most essential and perceived as the most significant privacy invasion; both combinations include the confirmed case's personal and route information. This study ultimately tried to suggest a way to lower the concern about privacy invasion of the confirmed cases without damaging the emergency alert text messages' essential information. We expect that this study will provide researchers and policymakers interested in disaster communication with valuable theoretical and practical implications.

Electroencephalography (EEG) is used for the diagnosis of epilepsy and testing the brain function. Clinical technologists are responsible for recording EEG without artifacts in accordance with the international 10~20 electrode system. Training on these techniques requires practical education. In the case of EEG, however, it is difficult for trainees to find the correct location of the electrode. Therefore, this study compared the time spent to locate the electrode attachment between traditional tape and the newly developed band. The time spent for sitting position patients using the band (196.7±61.8s) was 1084.3 s faster than the tape (1,281.0±457.4s) (P<0.001). Furthermore, the spend time spent for lying position patients using the band (200.2±49.3s) was 1217.7s faster than the tape (1417.9±482.3s) (P<0.001). Measurements using the band showed fewer differences due to various factors, such as position, practical experience, and gender. The newly developed band can locate the correct electrode attachment position quickly and efficiently, which has been a difficult problem in EEG practical education. In addition, this band is expected to be applied widely by new clinical technologists in the clinical field. Nevertheless, more study will be required to verify the accuracy of the location of the attaching electrode.

Selenium is an important trace mineral that plays an essential role in maintaining the body's immunity with oxidative stress defense and antioxidant activity, immunity, thyroid hormone control, defense against drug or heavy metal harm, and reducing the risk of chronic diseases. A selenium deficiency increases the risk of various chronic diseases, such as cancer, cardiovascular disease, diabetes, neurological disease, osteoarthritis, muscle necrosis and weakness, thyroid disease, and inflammatory diseases. This paper explains the criteria for establishing and revising selenium in the 2020 Dietary Reference Intake for Koreans (KDRIs) and reviews the current status of the selenium database and suggestions for setting the 2025 KDRIs in the future. In the 2020 KDRIs, the selenium intake with the maximum plasma selenoprotein P level was used as the criteria. The weight and coefficient of the variation were applied to the Chinese' reported values. Compared to 2015 KDRIs, there were some revisions in the selenium dietary reference intakes by gender and age according to the change in reference weight. To improve and revise selenium dietary reference intakes in the future, a selenium intervention study is needed to determine the maximum level of plasma selenoprotein P in Koreans. In addition, a revision of the selenium database of the nutritional assessment program (CAN-Pro 5.0) is needed. An analysis of the selenium content of foods should be expanded to assess the selenium intake accurately. In addition, research on the relationship between selenium intake and the biological indicators in the body is required for healthy people and subjects of special environments, such as patients and athletes with various oxidative stress.

Purpose: This study was conducted to examine the relationship among cognitive function, nutrition screening initiative (NSI) score, and food intake status. Methods: A total of 409 subjects aged over 60 years were recruited from the Yongin dementia prevention and control center. Mini Mental State Examination Dementia Screening (MMSE-DS) method was used to assess the cognitive function of the subjects. Information on health related behaviors and food intake was collected by face to face interview using a structured questionnaire. The questionnaires included the NSI DETERMINE checklist, food intake sheets by 24 hr recall method and by semi-quantified food frequency questionnaire. Results: Subjects were divided into low cognitive or normal groups according to the MMSE-DS result. The prevalence of low cognitive function in the subjects was 25.7%. The low cognitive group exercised less and had higher nutritional health risk than the normal group. The low cognitive group had lower consumption of polyunsaturated fatty acid and higher tendency of thiamin, riboflavin, and iron deficiency. The low cognitive group had less frequency of eating mackerel, pepper, tangerine, and watermelon and higher frequency of eating white rice and cookies than the normal group. Conclusion: The results of this study imply that the cognitive function of elderly is related to exercise behavior, nutritional health risk, and food and nutrient intake status.

Background : Diagnosing a pulmonary embolism is difficult because its presenting symptoms are nonspecific and there are limitations with all of the objective tests. The D-dimer is known to be a marker of the lysis of intravascular cross-linked fibrin as a result of the activation of the endogenous fibrinolytic pathways, and the D-dimer assay is these an objective method for diagnosing a pulmonary embolism. This study assessed the benefits of the D-dimer test for diagnosing a pulmonary embolism using semiquantitative latex agglutination. Methods : The latex agglutination results of 185 patients were retrospectively reviewed. The D-dimer test was performed at the time a pulmonary embolism was suspected. Ninety patients(group I) were diagnosis with PE through spiral chest CT or a chest CT angiogram, perfusion/ventilation scans, and/or pulmonary angiogram. Ninety-five patients (group II) were found not to have a pulmonary embolism through the above tests. Results : The male to female ratio and mean age in groups I and II was 37:55, and 57 years old to 50:45 and 52 years old, respectively. When the cut off value for a positive D-dimer assay was set to $500{\mu}g$, the sensitivity, positive predictive value, negative predictive value and specificity was 86.7%, 61.4%, 79.3%, and 48.4%, respectively. Conclusion : The semiquantitative latex agglutination method in the D-dimer test has a lower sensitivity and negative predictive value than the well known ELISA test particularly for small emboli. Therefore, this test is not a suitable screening test for excluding a pulmonary embolism.

Purpose : The reinfection rate of H. pylori reported before $^{13}C$-urea breath test($^{13}C$-UBT) era was higher than that of the post $^{13}C$-UBT era. Children are usually reluctant to receive invasive endoscopic evaluation for the reinfection of H. pylori, particularly when they are asymptomatic. The aim of the study is to discover the reinfection rate by different diagnostic tests, and to find out what causes the difference. Methods : Children confirmed to be eradicated from H. pylori were included in the study. Reinfection was evaluated by endoscopic biopsy based tests(n=34, mean age $11.5{\pm}3.7$ years) and/or a $^{13}C$-UBT(n=38, mean age $10.0{\pm}3.6$ years) at the time of 18 months after eradication. At first visit, H. pylori infection had been diagnosed by positive results from a rapid urease test, Giemsa stain and Warthin-Starry stain and/or a positive culture. Eradication was defined as negative results from all above tests 1-3 months after eradication therapy. Results : Reinfection rate by endoscopic biopsy based tests was 35.3 percent(12/34). All patients had abdominal symptoms(P=0.000). Reinfection rate was 13.2 percent(5/38) by a $^{13}C$-UBT. Reinfection rate was higher in children with abdominal symptoms(P=0.008). There was no evidence that reinfection rate depended on the sex(P=0.694), age(P=0.827), diseases(peptic ulcers vs gastritis, P=0.730) and eradication regimen(P=0.087). Conclusion : Helocibacter pylori reinfection rate in Korean children was 13.2 percent per 18 months by a non-invasive test or $^{13}C$-UBT. Accurate determinations of the reinfection rate in children is affected by the compliance of the diagnostic tests. Non-invasive tests should be considered to investigate the reinfection rate in children.
