Purpose: The purpose of this study was to examine the awareness of alcohol use during pregnancy and factors influencing the intention to abstain from alcohol during pregnancy by drinking levels. Methods: Utilizing a comparative descriptive design, a total of 359 female college students were recruited. Measurements were Theory of Planned Behavior (TPB) variables related awareness of alcohol use during pregnancy, Korean Version of the Alcohol Use Disorders Identification Test, knowledge about alcohol use during pregnancy, and socio-demographic factors. Main variables were compared by drinking levels. The factors influencing the intention to abstain from alcohol during pregnancy were identified using hierarchical regression analysis. Results: Non-problematic alcohol behavior group (n=185) had higher the intention to abstain from alcohol during pregnancy than problematic alcohol behavior group (n=174) (t=3.13, p=.002). The significant TPB variables influencing the intention to abstain from alcohol during pregnancy were that attitudes (β =-.44, p<.001), subjective norms (β =.14, p=.026), and perceived behavior control (β =.19, p=.002) in non-problematic alcohol behavior group, whereas the corresponding variables in the problematic alcohol behavior group were attitudes (β =-.51, p<.001) and subjective norms (β =.21, p=.006). Conclusion: It is necessary to increase the intention to abstain from alcohol during pregnancy for the female college students having problematic alcohol behavior. The following strategies are recommended for them; decreasing acceptable attitudes toward alcohol use during pregnancy and reinforcing the influence of social pressure toward to abstain from alcohol during pregnancy.

Purpose: The purpose of this study was to review health-related interventions in nursing studies for low-income school-age children and adolescents. Methods: Searches among CINAHL, MEDLINE, PubMed, EMBASE, DBpia, and RISS identified 27 intervention studies published from January 2000 to April 2018. Results: Twenty-seven intervention studies were identified: 12 included psychosocial adaptations and 15 included the healthy lifestyle promotion and disease prevention. The settings were mainly schools and community welfare centers. Many studies were based on social cognitive theory and interventions were provided in a group format. Depression, self-esteem, resilience, self-efficacy for vegetable and fruit consumption, physical activity, and health-related knowledge improved significantly after the health-related interventions. However, the findings were inconsistent with regard to anxiety, peer relationships, body mass index (BMI), blood pressure, cholesterol, and glucose. Conclusion: There is potential for enhancing outcomes for psychosocial, physical health, and health-related knowledge among low-income school-age children and adolescents. Integrated interventions addressing the physical as well as psychological health of low-income children and adolescents should be conducted. It would be prudent to consider the ethnicity and family background of the child or adolescent. However, rigorous study designs and scientific validation are needed for further evidence.

세계 인구의 고령화가 진행되는 오늘날 노인들을 위한 의료 서비스의 수요는 점차 증가할 것으로 보인다. 특히, 응급실을 방문하는 노인 환자는 일반 환자보다 다양한 질병을 갖고 있거나, 특이한 증상을 호소하는 등 복잡한 의학적, 사회적 및 신체적 문제를 가지고 있는 경우가 많다. 우리는 65세 이상의 응급실을 방문한 노인 환자의 사망률 예측을 위해 연령, 성별, 혈압, 체온, 혈액검사, 주증상명 등의 의료 데이터를 사용하였다. Feed Forward 신경망과 지지벡터기계를 각각 학습하여 사망률을 예측하고 그 성능을 비교하였다. 1개의 은닉층을 사용한 Feed Forward 신경망의 실험결과가 가장 좋았으며, 이 때 F1 점수는 52.0%, AUC는 88.6%이다. 좀 더 좋은 의료 자질을 추출하여 제안 시스템의 성능을 향상시킨다면 응급실에 방문한 노인 환자들을 위한 효과적이고 신속한 의료 자원 배분을 통해 더 좋은 의료 서비스를 제공할 수 있을 것이다.

Background: Recently obesity has become a social problem in all over the world including Korea. It is known that obesity is closely related with cardiovascular disease. Many studies are carrying out in the relation between several obesity indices, such as body mass index(BMI), waist-circumference(WC), body fat percent and risk factors of cardiovascular disease. Objective: This study was done in order to investigate correlation of obesity and cardiovascular risk factors. Method: We gathered totally 138 subjects who have taken health screening test in university hospital. With the exception of 40 abnormal cases on current illness and laboratory study, 98 healthy cases were analysed. We divided the groups as normal, overweight, obese group according to body mass index $(22.9kg/m^2\;and\;below\;/\;23{\sim}24.9kg/m^2\;/\;25kg/m^2\;and\;above)$and investigated the relationship between obesity based on body mass index(BMI) and cardiovascular risk factors. And investigated the relationship between each cardiovascular risk factor and body mass index, waist-hip ratio, body fat percent. Results: With the exception of blood pressure, other lab data such as total cholesterol, triglycerid, glucose were significantly different between the three groups divided by body mass index$(22.9kg/m^2\;and\;below\;/\;23{\sim}24.9kg/m^2\;/\;25kg/m^2\;and\;above)$. And Correlation coefficient of cardiovascular risk factors with body mass index, waist-hip ratio, body fat precent were acquired. Conclusion: We have concluded that the body mass index and waist-hip ratio body fat precent were predictive factors cardiovascular disease.

For many years, engineers in the field of acoustics have used the A-weighted sound pressure level (SPL). Since they were interested just in a reduction of noise, the A-weighted SPL was considered good enough to quantify noise problems. This is reasonable because loudness is usually the most important parameter for most noise problems and A-weighted SPL is often reasonably well correlated with loudness. As the overall noise levels drop, however, other parameters become more important and must be considered, Advent of sound quality came from an understanding that A-weighted SPL only reflects the loudness of a sound. It is obviously impossible to characterize a complex sound with a single number. Although product mostly has revealed physical quantities created by the standpoint of engineers, consumers perceive and evaluate products on the non-physical characteristics, such as feelings, emotions, and experiences in different social and cultural situations. Especially, for the household appliances for instance air-conditioner or refrigerator, the sound is heavily related to the satisfaction of a customer who is a real user of the product and is very important factor to decide purchasing as well as visual design. Therefore, in this research, the general tendency of consumer's psychology was investigated for the appliances. And also, in order to obtain clear guidelines fur sound manipulation, the characteristics of the sound of air-conditioning systems and refrigerators were compared with competitors'. since it is important to overcome the discrepancy between engineering and marketing, the relevance of sound manipulation must be documented from the consumer's perspective. That is the reason why we conducted a consumer and marketing oriented study.

Purpose: The aim of this study was to investigate the effects of metal artifacts on the accurate diagnosis of root fractures using cone-beam computed tomography (CBCT) images with large and small/limited fields of view (FOVs). Materials and Methods: Forty extracted molar and premolar teeth were collected. Access canals were made in all teeth using a rotary system. In half of the teeth, fractures were created by the application of mild pressure with a hammer. The teeth were then randomly put into a wax rim on an acryl base designed in the shape of a mandible. CBCT scans were obtained using a Newtom 5G system with FOVs of $18cm{\times}16cm$ and $6cm{\times}6cm$. A metal pin was then placed into each tooth, and CBCT imaging was again performed using the same fields of view. All scans were evaluated by two oral and maxillofacial radiologists. The specificity, sensitivity, positive predictive value, negative predictive value, and likelihood ratios (positive and negative) were calculated. Result: The maximum levels of sensitivity and specificity (100% and 100%, respectively) were observed in small-volume CBCT scans of teeth without pins. The highest negative predictive value was found in the small-volume group without pins, whereas the positive predictive value was 100% in all groups except the large-volume group with pins. Conclusion: The specificity of CBCT decreased with the presence of a pin in the large-volume group, but not in the small-volume group.

Stroke patient needs rehabilitation after receiving an acute treatment in a hospital. When stroke patient gets involved in an early discharge program, home care nurse plays a pivotal role to make them to gain a full strength and to come back to his/her prior life before he/she is sick. In spite of the importance of home care nursing intervention protocol for home care nurses to perform home care nursing autonomously, home care nursing intervention protocol for stroke patient is rarely developed. Therefore this study was conducted to develop home care nursing protocol that is applicable for stroke patients in home care nursing area. 41 home care nursing charts for stroke patients registered in home care nursing agencies from December 1st 1994 to August 31st 1999 at Y hospitals in Seoul and Won-Ju city were analyzed. 44 home care nurses who were having over three years' experience on stroke patients were participated in this study as a user validity validation group. The results of this study are as follows. 1. 28 nursing diagnoses were selected on the basis of evaluation of nursing diagnoses of stroke patients presented in a previous literature and case studies on home care nursing. 2. 17 nursing diagnoses were classified through the frequency analysis of home care nursing charts for 41 stroke patients who had received home care nursing. The order of sequence was like these: impaired skin integrity, risk for infection, nutritional deficit, impaired physical mobility, constipation, knowledge deficit, ineffective airway clearance, anxiety in family members, risk for aspiration, self care deficit, altered urinary elimination, ineffective individual coping, social isolation, risk for injury, self-esteem disturbance, impaired verbal communication, fatigue of family caregiver. 3. Based on validation on expert and user validities, 44 nursing interventions which were above ICV=.80 were chosen. 4. Nursing intervention protocols which showed above ICV=.90 were developed and were like these; pressure ulcer care, position change, preventive care for circulatory dysfunction, tube care : catheter, vital sign monitor, constipation/impaction management, artificial airway management, suction of airway secretion, environmental management : safety, and fall prevention.
