Purpose: The researchers reviewed the previous studies on the psychological anxiety and economic damage during the recent COVID-19 pandemic to understand the satisfaction, awareness and attitude of the residents in Jeju, Korea. Research design, data and methodology: 215 samples based on self-reported survey were collected for path analysis focused on controlling variables in demographic characteristics in PLS-SEM using Smart PLS 3.0. Results: The researchers found the Satisfaction with COVID-19 Prevention Measures and the Awareness of Tourism Crisis affect Attitude toward Tourism of the residents with the explanatory power (R² = 0.209). Age was found to be the only significant controlling variable in this model for the Awareness of Tourism Crisis to Attitude toward Tourism. Conclusions: The attitude toward tourism is influenced by the level of satisfaction of the prevention service for COVID-19 as well as the awareness of the crisis. Residents have different level of the tourism crisis awareness by the status of their economic activities while there is no differences in all age groups for satisfaction in the quarantine service. The study suggests that the importance of the public health service should be preferentially concerned for residents to have stable economic activities where the tourism is the major industry.

To set the estimated energy requirement (EER) in Dietary Reference Intakes for Koreans (KDRI), we need the coefficient by physical activity stage, as determined by the physical activity level(PAL). Thus, there has been demand for a tool to calculate PAL based on the physical activity diary. This study was undertaken to develop a physical activity (PA) classification table for Koreans, using the 2011 Compendium of physical activities in the United States. The PA classification table for Koreans contains 262 codes, and values of the metabolic equivalent of task (MET) for specific activities. Of these, 243 PAs which do not have Korean specific data or information, were selected from the 2011 Compendium of PAs that originated in the United States; another 19 PAs were selected from the previous research data of Koreans. The PA classification table is codified to facilitate the selection of energy values corresponding to each PA. The code for each PA consists of a single letter alphabet (activity category) and four numeric codes that display the activity type (2 digit number), activity intensity (1 digit number), and specific activities (1 digit number). In addition, the intensity (sedentary behavior, low, middle and high) of specific PA and its rate of energy expenditure in MET are presented together. The activity categories are divided into 4 areas: Daily Activity (A), Movement (B), Occupation (C), and Exercise and Sports (D). The developed PA classification table can be applied to quantify the energy cost of PA for adults in research or practice, and to assess energy expenditure and physical activity levels based on self-reported PA.

Purpose: The aim of this study was to evaluate and compare the accuracy performance of dental professionals in the classification of different types of dental implant systems (DISs) using panoramic radiographic images with and without the assistance of a deep learning (DL) algorithm. Methods: Using a self-reported questionnaire, the classification accuracy of dental professionals (including 5 board-certified periodontists, 8 periodontology residents, and 31 dentists not specialized in implantology working at 3 dental hospitals) with and without the assistance of an automated DL algorithm were determined and compared. The accuracy, sensitivity, specificity, confusion matrix, receiver operating characteristic (ROC) curves, and area under the ROC curves were calculated to evaluate the classification performance of the DL algorithm and dental professionals. Results: Using the DL algorithm led to a statistically significant improvement in the average classification accuracy of DISs (mean accuracy: 78.88%) compared to that without the assistance of the DL algorithm (mean accuracy: 63.13%, P<0.05). In particular, when assisted by the DL algorithm, board-certified periodontists (mean accuracy: 88.56%) showed higher average accuracy than did the DL algorithm, and dentists not specialized in implantology (mean accuracy: 77.83%) showed the largest improvement, reaching an average accuracy similar to that of the algorithm (mean accuracy: 80.56%). Conclusions: The automated DL algorithm classified DISs with accuracy and performance comparable to those of board-certified periodontists, and it may be useful for dental professionals for the classification of various types of DISs encountered in clinical practice.

Purpose: This study aimed to identify the relationship between the experiences of workplace violence and post-traumatic stress disorder and the moderating effect of resilience and social support at work on the relationship in tertiary hospital nurses. Methods: This was a descriptive correlation study to confirm the moderating effect of resilience and social support at work on the factors affecting post-traumatic stress disorder for nurses who have experienced violence. A total of 146 registered nurses were recruited from a tertiary hospital from March to July 2020. The Participants who worked for more than one year and experienced violence at work completed self-reported questionnaires that measured the experiences of workplace violence and post-traumatic stress disorder, resilience, social support at work, and demographic information. The collected data were analyzed using t-test, ANOVA, Pearson's correlation coefficient, and hierarchical regression analysis. Results: The nurses experienced verbal abuse an average of 3.70±2.06 times a week, physical threat an average of 2.30±1.71 times a month, and physical assault an average of 0.76±0.82 times a year. The Experiences of workplace violence were significantly increased post-traumatic stress disorder. The result also showed that resilience moderated the relationship between the experience of verbal abuse and post-traumatic stress disorder in hospital nurses. However, there was no significant moderating effect of social support between workplace violence and post-traumatic stress disorder. Conclusion: The experiences of workplace violence influenced post-traumatic stress disorder in nurses and were moderated by resilience. Therefore, hospital administrators need to develop and provide a workplace violence prevention and resilience reinforcement program to reduce post-traumatic stress disorder in nurses. In addition, we suggest further research on the effect of social support in a workplace on the experiences of violence.

It is known that chronic pain and injury of upper limb joint tissue in manual wheelchair users is usually caused by muscle imbalance, and the propulsion speed is reported to increase this muscle imbalance. In this study, kinematic variables, electromyography, and ultrasonographic images of the upper limb were measured and analyzed at two different propulsion speeds to provide a quantitative basis for the risk of upper extremity joint injury. Eleven patients with spinal cord injury for the experimental group (G_E) and 27 healthy adults for the control group (G_C) participated in this study. Joint angles and electromyography were measured while subjects performed self-selected comfortable and fast-speed wheelchair propulsion. Ultrasound images were recorded before and after each propulsion task to measure the acromiohumeral distance (AHD). The range of motion of the shoulder (14.35 deg in G_E; 20.24 deg in G_C) and elbow (5.25 deg in G_E; 2.57 deg in G_C) joints were significantly decreased (p<0.001). Muscle activation levels of the anterior deltoid, posterior deltoid, biceps brachii, and triceps brachii increased at fast propulsion. Specifically, triceps brachii showed a significant increase in muscle activation at fast propulsion. AHD decreased at fast propulsion. Moreover, the AHD of G_E was already narrowed by about 60% compared to the G_C from the pre-tests. Increased load on wheelchair propulsion, such as fast propulsion, is considered to cause upper limb joint impingement and soft tissue injury due to overuse of the extensor muscles in a narrow joint space. It is expected that the results of this study can be a quantitative and objective basis for training and rehabilitation for manual wheelchair users to prevent joint pain and damage.

작업관련 근골격계 질환은 중요한 직업병 중 하나이며, 이는 치과의료 직종도 예외일수는 없다. 치과위생사는 주로 장시간 서서 진료를 하거나 머리와 목을 구부리고 어깨와 손을 많이 틀면서 움직이거나 부적절한 자세로 진료하는 경우가 많기 때문에 더욱 더 근골격계 질환에 대한 위험에 대한 노출도 크다. 따라서 본 연구는 작업과 관련하여 근골격계의 부위별 통증의 유무와 업무분야별 통증의 차이가 있는지를 알아보기 위하여 수도권 지역의 치과위생사 300명을 대상으로 설문조사를 하였고 이 중 268명이 설문에 응하였다. 본 연구의 결과는 다음과 같이 요약될 수 있다. 1. 연구대상자들의 신체부위별 근골격계 통증 정도를 분석해 본 결과, 어깨 90.3%, 목 89.2%, 다리 83.6%, 허리 81.7%, 손/손목/손가락 75.7%, 팔/팔꿈치 52.8%로 나타났다. 2. 연구대상자들의 업무영역에 따라서 근골격계 질환이 다르게 나타났으며 연구결과, 외과업무의 경우 목, 허리, 다리, 어깨, 손, 팔로 나타났으며 보철업무의 경우 어깨, 다리, 손, 목, 허리, 팔로 나타났다. 교정업무의 경우 목, 어깨, 손, 허리, 다리, 팔로 나타났고 접수의 경우 목, 어깨, 허리, 다리, 손, 팔로 나타났다. 모든 치료의 경우 어깨, 허리, 목, 다리, 손, 팔로 나타났다. 여기서 나타난 것처럼 연구대상자들이 주로 하는 진료에 대한 근골격계 통증이 신체부위별로 다르다는 연구결과가 나왔다. 3. 근골격계 질환의 주요변인에 대한 연구결과, 일반적 특성은 통계적으로 유의하지는 않았지만 신장이 큰 연구대상자들에게 허리와 어깨의 통증이 많았고 체중이 적게 나가는 연구대상자들은 목과 팔의 통증이 높았다. 연령은 29~33세는 어깨, 34세 이상에서는 팔/팔꿈치가 높았으며 이는 통계적으로 유의하였다(p<0.05). 근무환경은 경력이 높아질수록 손/손목/손가락은 통증이 증가하였고(p<0.05) 목과 어깨(p<0.05), 팔(p<0.01), 허리는 3~4년의 경력에서 가장 높았다. 그리고 다리/발은 1~2년의 경력에서 통증경험이 높았다. 근무시간은 시간이 증가함에 따라 목에 대한 통증이 높아진다고 하였으나 유의한 차이는 없었다. 그러나 손/손목/손가락에서는 근무시간이 적을 때 높은 통증경험을 나타냈으며 통계적으로 더욱 유의한 차이를 보였다(p<0.01). 근무처에 따라서 분과병원에서는 손/손목/손가락에서 높은 통증경험율을 나타냈고(p<0.05) 중소치과에서는 다리/발에서 높은 통증경험률을 나타냈다(p<0.05). 이와 같은 결과는 치과위생사의 근골격계 질환은 평균이상으로 많으며 이 질환에 대한 위험성을 인식하고 경각심을 느껴야 한다고 보여진다. 근골격계 질환은 초기에 발생되면 간단하게 치료받을 수 있지만 누적되어서 오랫동안 방치되었을 때는 이미 정상으로 되돌릴 수 없기 때문에 올바른 자세를 유지하고 통증이 나타나거나 피로가 쌓일 경우 즉시 치료를 하고 적극적인 자세로 응대하고 지속적인 노력이 필요하다고 보여진다.

This study aims at examining perception of body weight control and lifestyles and food habits of under-weight, normal-weight and over-weight female college students. The data analysis were conducted by a body fat analyzer and questionnaires. The subjects were 368 female college students divided into three groups: the under-weight(UW), the normal-weight(NW), and the over-weight(OW), according to the guidelines of the Korean Society for the Study of Obesity(2000). Among the subjects, 18.2% were under-weight, 63.6% normal-weight, and 18.2% over-weight. Mean of body weights were 45.4kg, 53.3kg, and 63.7kg, and BMIs were $17.5kg/m^2$, $20.5kg/m^2$ and $24.6kg/m^2$ in the UW, NW, and OW groups, respectively. 'Self assessment of body weight' was significant at the level of p<0.001 according to the Obesity Index. Of the UW group, 41.8% considered their weight to be normal and 4.5% believed they are over-weight. In the NW group, 43.2% thought they are over-weight, 1.5% believed they are under-weight. 57.1 % of the UW group and 98.6% of the NW group had ever tried to reduce their weight. Their 'exercise frequency and exercise time' were not significant by the 01. 'Regularity in the daily life' of the subjects was significant at the level of p<0.05. 43.3 % of the OW group answered that they don't live regular daily lives. 'Sleeping time' of the subjects was significant at the level of p<0.05 by the 01. 41.8% of the OW group reported that they sleep 'between 7 and 8 hours a day' which was the highest rate among the three groups. 'Frequency of meals per day' was not significant by the OI. 'The speed of eating meals' was significant at p<0.01, 23.9% of the UW group, 31.2% of NW group, and 38.8% of OW group reported that they have meals 'in a very fast speed'. Concludingly, most of female college students conceive themselves as having inappropriate body image, which means that they need to be given additional education about nutrition and diet.

연구목적 본 연구의 목적은 조현병 외래 환자를 대상으로 야간식이증후군(night eating syndrome : NES)의 유병률과 이와 관련된 임상적 요인들에 대해 살펴보는 것이다. 방 법 정신건강의학과 외래를 방문한 201명의 조현병 환자들을 14 문항의 자기보고 형식인 야간식이증후군 설문지(Night Eating Questionnaire : NEQ)로 평가하였다. 인구학적, 임상적 특징과 체 질량 지수(BMI)을 조사하였고, 주관적인 기분과 수면, 폭식과 체중 관련 삶의 질에 대해서는 각각 Beck's Depression Inventory(BDI), Pittsburgh Sleep Quality Index(PSQI), Binge Eating Scale(BES)와 Korean version of Obesity-Related Quality of Life Scale(KOQoL)를 이용하여 평가하였다. 결 과 조현병 외래 환자에서 야간 식이 증후군의 유병률은 10.4%(201명 중 21명)이었다. NES 군과 non-NES 군간에 나이를 제외하면 인구사회학적 및 임상적 특성, BMI에서는 유의한 차이를 보이지 않았다. NES 군이 Non-NES 군에 비해 보다 우울했고, 수면과 폭식 양상, 체중 관련 삶의 질에 있어서 의미 있는 장애를 나타냈다. '아침 식욕부진'과 '지연된 아침식사'(NEQ에서 NES 핵심 항목 5개 중 2개)는 두 군간에 차이가 없었으나, '야간 섭식', '야간 식욕항진' 그리고 '기분/수면'은 NES 군에서 더 손상되어 있는 것으로 나타났다. 결 론 본 연구는 조현병 외래 환자를 대상으로 NES의 유병률과 관련 요인에 대해 기술한 최초의시도이다. 비록 NES와 비만과의 연관성은 밝히지 못했지만, 본 연구의 결과는 NES가 정신 건강에 부정적 영향을 준다는 사실을 보여주었다. 향후 이러한 결과를 뒷받침할 수 있는 추가 연구가 필요할 것이다.

Background: The objective of this study is to determine knowledge about lung cancer among secondary school male teachers in Kudat, Sabah, Malaysia. Materials and Methods: A cross-sectional study was conducted among three secondary schools located in Kudat district, Sabah, Malaysia during the period from June until September 2012. The protocol of this study was approved by ethics committee of Management and Science University, Malaysia. The aims were explained and a consent form was signed by each participant. Respondents were chosen randomly from each school with the help of the headmasters. Self-administrated questionnaires, covering socio-demographic characteristics and general knowledge of lung cancer, were distributed. Once all 150 respondents completed the questionnaire, they passed it to their head master for collecting and recording. All the data were analyzed using Statistical Package for the Social Sciences (SPSS) version 13. ANOVA and t-test were applied for univariate analysis; and multiple linear regression for multivariate analysis. Results: A total of 150 male secondary school teachers participated in this study. Their mean age was $35.6{\pm}6.5$ (SD); maximum 50 and minimum 23 years old. More than half of the participants were Malay and married (52%, 79%; respectively). Regarding the knowledge about lung cancer, 57.3% of the participants mentioned that only males are affected by lung cancer. Some 70.7% mentioned that lung cancer can be transmitted from one person to another. More than half (56.7%) reported that lung cancer is not the leading cause of death in Malaysian males. As for risk factors, the majority reported that family history of lung cancer is not involved. However, 91.3% were aware that cigarettes are the main risk factor of lung cancer and more than half (52%) believed that second-hand smoking is one of the risk factor of lung cancer. More than half (51.3%) were not aware that asbestos, ionizing radiation and other cancer causing substances are risk factors for lung cancer. Quitting smoking, avoiding second-hand smoking and avoiding unnecessary x-ray image of the chest (53.3%, 96.0%, 87.3%; respectively) are the main preventive measures mentioned by the participants. For the factors that influence the participants knowledge, univariate and multivariate analysis showed that only race was significant. Conclusions: Overall, the knowledge of school male teachers about lung cancer was low. However, few items were scored high: cigarettes are the main risk factor; avoiding second-hand smoking; and avoiding x-rays. Interventions to increase lung cancer awareness are needed to improve early detection behavior. Increase the price of pack of cigarettes to RM 20 and banning smoking in public places such as restaurants are highly recommended as primary preventive measures.
