Nutritional assessment for the elderly can identify health status and morbidity. However, development of Nutritional Risk Index (NRI) remains limited for elderly because of difficulties in understanding physiological mechanism of elderly. This study was performed to analyze and develop Nutritional Risk Index for Korean elderly Women (Geriatric Nutritional Risk Index, GNRI). Based on literature review, factors for NRI were identified and indices were assessed by a cross-sectional survey. The survey involved Korean elderly women (${\geq}$60, n = 94) in Gwangju area, and sociodemographics, lifestyle characteristics, health conditions, dietary intakes based on 24h- recall, anthropometric measures (wt, ht, BMI, waist, hip, WHR, body protein, body fat, abdominal fat, and triceps skinfold thickness), and clinical biochemistry parameters (systolic blood pressure, diastolic blood pressure, cholesterol, HDL-cholesterol, triglyceride, total protein, albumin, prealbumin, hemoglobin, hematocrit, fasting blood glucose, HbAlc, ferritin, Zn, Ca, Na, K, Vit E, Vit $B_{12}$, folate, C-reactive protein) were examined relation to nutritional risk index. Based on literature review and data analyses, three NRIs were categorized (NRI I, NRI II, NRI III) and used for further analysis. NRI I was related to having metabolic syndrome, NRI II was related to serum albumin and body weight, and NRI III was related to food habit and health concerns. Abdominal fat (%) of elderly was correlated with each NRIs. NRI II was correlated with nutritional deficiency and higher tendency of inflammatory response, and NRI III was correlated with nutritional status which tend to be lower on aging (protein, folate, Vit $B_{12}$). NRI can serve as a useful tools in assessing health risk and nutritional status. Some modification of items in NRI and validity study are need to apply to Korean elderly.

Purpose: Obstructive sleep apnea (OSA) is a common medical disorder with serious complications if untreated. Dentists play a vital role in the early diagnosis of this condition, thereby improving patients' prognoses. The purpose of this study was to identify patients with a high risk of OSA using simple cephalometric measurements in patients receiving routine dental care. Materials and Methods: The present study was conducted on 206 patients divided into a high-risk group and a control group after answering the Berlin questionnaire. Cephalometric analysis of a digital cephalogram was performed to measure the upper airway diameter (UAD) and mandibular-to-hyoid bone distance (MP-H) by 2 observers at 2 different times. Results: Among 206 patients, 93 (45%) were included in the high-risk group and 113 (55%) were in the control group. No significant difference was present between the groups with regard to gender, and the patients ranged in age from 18 to 65 years. The UAD measurements in the high-risk group were significantly lower than in the control group, and the MP-H measurements were significantly higher in the high-risk group than in the control group. The UAD was lower in middle-aged patients in both groups. Conclusion: Our study found that the UAD was lower in individuals with a high risk of OSA. Also, we found that middle-aged individuals of both genders were more likely to develop OSA. Dentists play a vital role in diagnosing patients at a high risk for OSA via thorough clinical examinations, risk factor analyses, and simple cephalometric analyses.

The objective of this study was to evaluate the risk of illness from Campylobacter spp. on ham. To identify the hazards of Campylobacter spp. on ham, the general characteristics and microbial criteria for Campylobacter spp., and campylobacteriosis outbreaks were investigated. In the exposure assessment, the prevalence of Campylobacter spp. on ham was evaluated, and the probabilistic distributions for the temperature of ham surfaces in retail markets and home refrigerators were prepared. In addition, the raw data from the Korea National Health and Nutrition Examination Survey (KNHNES) 2012 were used to estimate the consumption amount and frequency of ham. In the hazard characterization, the Beta-Poisson model for Campylobacter spp. infection was used. For risk characterization, a simulation model was developed using the collected data, and the risk of Campylobacter spp. on ham was estimated with @RISK. The Campylobacter spp. cell counts on ham samples were below the detection limit (<0.70 Log CFU/g). The daily consumption of ham was 23.93 g per person, and the consumption frequency was 11.57%. The simulated mean value of the initial contamination level of Campylobacter spp. on ham was −3.95 Log CFU/g, and the mean value of ham for probable risk per person per day was 2.20×10⁻¹². It is considered that the risk of foodborne illness for Campylobacter spp. was low. Furthermore, these results indicate that the microbial risk assessment of Campylobacter spp. in this study should be useful in providing scientific evidence to set up the criteria of Campylobacter spp..

Standard combination chemotherapy including isoniazid, rifampin, pyrazinamide, and ethambutol is very effective against tuberculosis. But, these medicines can cause hepatotoxicity which is the main reason for treatment interruption or change in drug regimen. In order to identify risk factors associated with hepatotoxcity in Koreans and assess elevated baseline LFTs' contributions to hepatotoxicity, a retrospective case control study was performed. The medical records of 277 patients who diagnosed with tuberculosis at a community hospital from January 1st, 2007 to June 30th, 2010 were reviewed. Patients were categorized into 3 groups (non toxic group, patients without increase in LFT levels; mild to moderate hepatotoxic group and severe hepatotoxic group). And the correlation between risk factors and hepatotoxicity was analyzed by using SPSS program. The overall incidence of hepatotoxicity was 18% and 8.7% of patients developed severe toxicity. Patients in the severe toxic group had the longest treatment period among the three groups. In 75% of severe toxic group, hepatotoxicity occurred within 18.3 days after starting medication. Hypoalbuminemia (serum albumin <3 g/dl) was a significant risk factor for development of severe toxicity. Elevated baseline transaminase (except ALT), total bilirubin, and preexisting hepatitis were also risk factors which were more than twice as likely to increase risk of severe hepatotoxicity (p>0.05). In conclusion, hypoalbuminemia (serum albumin level <3 g/dl) was a significant risk factor for anti-tuberculosis druginduced severe toxicity. Therefore, before starting antituberculosis chemotherapy, serum albumin level should be assessed at baseline. In high-risk patients (hypoalbuminemia, elevated LFTs) for hepatotoxicty, liver function should be closely monitored up to at least 21 days after taking medication.

Objectives: The purpose of this study was to identify the factors which affect risk perception and attitude on government risk management over medications containing asbestos among parents of elementary school students. Methods: This research design was cross-sectional study using self-administered questionnaire. The survey subjects were parents of elementary school students in Seoul, total of 1,051 subjects. The survey period was from June through July of 2011. The collected data were analyzed using the SPSS 20.0. Results: The subjects perceived high risk regarding medications containing asbestos. About 83.6% of the subjects perceived that the result taking of medications containing asbestos was fatal, 82.8% felt that medications containing asbestos was a very serious social problem, 79.5% agreed that medications containing asbestos was a new type of threat. The risk perception for medications containing asbestos was related to political affiliation, attitudes of dealing medicines, main use of media, and personal communication credibility. Those who did not believe that the current government policy was correct and the government was working toward the public's benefit and not its own had the higher level of negative attitudes towards the government's risk management over the case of medications containing asbestos. Conclusion: In implementing government policy, all information should be efficiently and accurately communicated through a transparent implementation process. Also, the government must have plans for countermeasures in case of an emergency and respond efficiently in order to maintain their credibility. Moreover, this highlights the need for health authorities to exert more effort in increasing public education/awareness, especially those concerning drug and dug-taking behavior, in order to harness positive attitude and trust towards the government's policy. For a more effective risk communication, the media, health experts, government representatives, and related industries should work together.

PURPOSE: The purpose of this study is to identify the incidence of chronic obstructive pulmonary disease (COPD) and risk factors for diseases in adults over 40 years of age in Korea, and to provide basic data for the prevention of COPD incidence through management. METHODS: Based on the 2019 data of the Korea National Health and Nutrition Examination Survey (KNHANES), 1,788 adults over the age of 40 who participated in pulmonary function test and health survey were selected as subjects. COPD incidence risk factors were analyzed using complex sample multiple logistic regression analysis. RESULTS: As a result of the analysis, the incidence of COPD in Korea was 11.5%, and the risk of developing COPD was higher in men, age, and current smokers. Compared to women, men had an increased risk of developing COPD by 2.369 times (95% CI 1.289-4.355). In age, the risk of COPD incidence increased by 3.702-fold (95% CI 1.923-7.124) in their 50s, 11.238-fold (95% CI 6.009-21.017) in their 60s, and 28.320-fold (95% CI 14.328-55.977) in their 70s compared to those in their 40s. In the smoking state, 2.302 times (95% CI 1.373-3.860) of past smokers and 4.542 times (95% CI 2.694-7.658) of current smokers were found to have a higher risk of developing COPD than non-smokers. CONCLUSION: To reduce the incidence of COPD, interventions are required to prevent disease development through lifestyle and smoking cessation education in subjects with COPD risk factors.

Objective: Infection is very common in the elderly, so there is a high prevalence of antibiotics use among this population. Especially, due to the emergence of resistant bacteria, the use of vancomycin is growing. The purpose of this study was to evaluate risk factors associated with vancomycin-induced nephrotoxicity in elderly patients. Methods: The subjects of this study were patients over 18 years old who received intravenous vancomycin in a general hospital located in Gangneung-si, Korea between August 1, 2013 and July 31, 2015. Data collection regarding vancomycin use and baseline characteristics was conducted using computerized hospital database. Logistic regression analysis was used to identify risk factors associated with vancomycin-induced nephrotoxicity. Results: A total of 290 patients were finally included, and 191(66%) out of these patients were age 65 or older. The incidence of vancomycin-induced nephrotoxicity was 11.0%, 12.6%, and 7.0% in the all adult patients, the elderly patients, and the non-elderly patients, respectively. There were significant differences in comorbidities between patients with nephrotoxicity and patients without nephrotoxicity in the all adult patients, and there were significant differences in vancomycin duration, comorbidities, and number of nephrotoxic agents between patients with nephrotoxicity and patients without nephrotoxicity in the elderly patients. However, according to the logistic regression analysis, there was no significant risk factor that increases the incidence of vancomycin-induced nephrotoxicity in all three age groups. Conclusion: There were no differences in risk factors that increase the incidence of vancomycin-induced nephrotoxicity between all adult patients, elderly patients, and non-elderly patients. Further studies with larger sample sizes to identify risk factors associated with vancomycin-induced nephrotoxicity in the elderly to improve the outcome of pharmacotherapy are required.

본 연구에서는 위험과 안전에 대해 실존심리학적 관점의 고찰을 실시하였다. 실존주의 철학과 실존주의 심리학적 논의들을 통해서 실존적 과제로서 '위험'을 파악하였으며, 실존적 욕구로서 '안전'을 규정하였다. 나아가 실존적 과제의 미해결성과 실존적 욕구의 비충족성으로 인해 발생되는 실존적 불안으로서 '주관적 위험'을 파악할 수 있음을 제시하였다. 또한, 실존적 불안으로서 '주관적 위험'은 '위험'과 '안전'에 대한 실존적 직면과 완성으로 나아가게 하는 나침판으로서 역할을 하고 있음과 발현된 현상적 상태를 통해 문제적 고착 상태에 놓여 있음을 파악할 수 있는 신호로서의 기능을 수행하고 있음을 밝혔다. 그리고 실존적 불안으로서 '주관적 위험'의 문제적 고착 양상은 발현된 현상에 대칭적인 특성과 상태로 인식될 수 있는 경험과 정보를 공급하는 방법을 통해서 조절할 수 있음을 제안하였다. 실존심리학적 관점으로 '위험'과 '안전'을 파악하려는 시도는 세월호 참사를 비롯한 한국 사회의 인재형 사고에 대해 보다 근원적인 원인 분석과 대책을 마련해 줄 수 있을 것이라고 생각한다. 이를 통해 향후 위험 감소와 안전 향상을 위한 심리학적인 접근을 보다 다양한 방면에서 효과적으로 적용할 수 있는 시사점을 제시해 줄 수 있을 것이다. 또한, 본 연구를 통해 제시된 여러 견해들을 종합해서 다양한 실존적 주제들의 상태를 조절하는 방법[주제상태조절이론(Theme Condition Adjustment Theory: TCAT)]에 대한 이론적 토대를 마련할 수 있을 것이라고 기대한다.
