차량 운전자는 안전을 위해 항상 자신의 차량의 상태를 점검하고 파악하는 것이 필수이다. 하지만 운전자가 차량의 상태를 알고자 한다면 전문 업체에게 의뢰하기 때문에 운전자는 시간과 금전적인 비용이 지불되어야 한다. IT 기술의 발달로 인해 스마트폰의 다양한 기능을 이용하여 차량의 상태 점검을 할 수 있게 되었지만, 기존 스마트폰 자동차 진단 시스템은 자동차의 전문적인 지식을 학습해야 차량 상태를 알 수 있기 때문에 사용자들에게 진단기의 필요성이 부각되지 않는다. 본 논문에서는 OBD-II 프로토콜 변환 WiFi 커넥터를 통해 받아오는 OBD-II 정보를 차량 운전자에게 필요한 차량 소모품 교체 주기의 점검, 차량 문제점 진단 정보를 사용자에게 실시간으로 보여주며 손쉽게 사용할 수 있는 자동차 소모품 구현을 iPhone에서 구현 하였다.

The Purpose of this study was to investigate the dietary intake of nutrients and the use of vitamin and mineral supplements by Korean college students attending Web class and the socioeconomic, dietary and health-related factors involved. The subjects were 137 male and 115 female students amending a health and nutrition-related Web class at a cycler university. This cross-sectional survey was conducted by self-administered questionnaire and the data were analyzed by SAS and SPSS PC package programs. Nutrient intake data collected using three-day recall method were analyzed by the Computer Aided Nutritional Analysis Program. Average intake by male students of most nutrients except energy, vitamin B$_2$ and calcium and intake by female students of those except energy, vitamin $B_2$, calcium and iron was higher than Korean RDA. Nutrient intake of male students was significantly influenced by the mother s job, skipping meals, exercise, vitamin and mineral supplement use, flood supplement use and self-evaluated anemia. Skipping meals and flood supplement use significantly influenced the nutrient intake of female students. A total of 47.4% of male students and 53.9% of female students were vitamin and mineral supplement users. In female students, socioeconomic characteristics such as the father s education level and household income were significantly different between vitamin and mineral supplement users and non-users. In both male and female students, there were significant differences in cross analysis between vitamin and mineral supplement use and flood supplement use. As for the self-reported health status of male and female students, vitamin and mineral supplement users perceived their health status to be worse compared to non-users. Therefore, nutrition education via the Internet is necessary in order to encourage college students to practice optimal nutrition strategies, including maintaining well-balanced diets by choosing various floods wisely.

When modeling event times in biomedical studies, the outcome might be incompletely observed. In this paper, we assume that the outcome is recorded as current status failure time data. Despite well-developed literature the routine practical use of many current status data modeling methods remains infrequent due to the lack of specialized statistical software, the difficulty to assess model goodness-of-fit, as well as the possible loss of information caused by covariate grouping or discretization. We propose a model based on pseudo-observations that is convenient to implement and that allows for flexibility in the choice of the outcome. Parameter estimates are obtained based on generalized estimating equations. Examples from studies in bile duct hyperplasia and breast cancer in conjunction with simulated data illustrate the practical advantages of this model.

This study aims to provide basic data to suggest guidelines for re-education and work improvement of modelists based on the analysis of the current status of modelist work and education. A survey was conducted from January 4 to May 15, 2020, targeting 44 people working in pattern, pattern CAD, and grading in domestic apparel companies. Descriptive statistical analysis and frequency analysis using SPSS 25 were employed to analyze the status of work type, work difficulties, and re-education. For pattern production, the rate of using pattern CAD for business was high. It was found that companies mainly use YUKA CAD (63.8%), and branded companies use pattern CAD (100%). It was found that 3D CAD is mostly employed by vendors (88.9%), and CLO (90%) is mainly used. Regarding difficulties in pattern making, it was found that they experienced difficulties with stretchable materials owing to the amount of shrinkage and sagging of the fabric. The work problem was the lack of requisite working hours owing to the volume of work. Regarding future re-education, 63.6% of the total respondents indicated that they required a course related to pattern correction and material. Moreover, it was found that re-education was necessary to upgrade technology and acquire new knowledge, however, information on re-education was insufficient.

Background: Nursing college students are exposed to information about diseases or drugs, and are likely to have a distorted perception of drug knowledge or behavior. The study aimed to identify knowledge and attitude about drugs and current status of self-medication among nursing students. Methods: The subjects were 172 nursing students from a university in Busan. Data were collected with structured questionnaires and analyzed using descriptive analysis, t-test, and one-way ANOVA using SPSS 23.0. Results: Nursing students had a high level of knowledge about drugs, but attitudes toward drugs were relatively low. 83.7% of patients had experience of self-medication. The methods to acquire information for self-administration were 29.9% by smart phone and 27.1% by internet. The use of nonsteroidal anti-inflammatory drugs (NSAIDs) among self-medication drugs was the highest. The most common reason for self-medication was 'I thought it to be a mild disease', and the pharmacists were the most affected by choice of self-medication. The knowledge about drugs was statistically significant according to grade, school life satisfaction and subjective health status. The attitudes about medication were statistically significant according to grade and self-medication experience. Conclusion: Nursing college students need drug safety education to improve awareness and practice of correct drug use.

Background: Depression is a comorbid disabling problem and potentially affects patient likelihood of survival. The aims of this study were to recognize the characteristics of depression and investigate associated predictor factors in patients with oral cancers. Methods: A cross-sectional and correlational design was used to collect data for this study conducted in northern Taiwan. A set of questionnaires was used to measure depression, symptom distress, performance status, social support, and demographic and disease-related information. Logistic regression was conducted to determine important factors predicting depression. Results: A total of 132 oral cancer patients participated in this study. Of these, 18.2% were identified as depression cases. The patient average performance status score was 90 or higher. Patients reported mild-to-moderate levels of symptom distress. The majority of social support was from families. Religious belief, alcohol use, symptom distress, and social support from family were found to be important factors predicting depression. Patients with religious belief with alcohol use reported greater symptom distress, and those with lower levels of social support from families were significantly more likely to develop depression. Conclusions: Clinicians should assess patient emotional status and manage symptoms in a timely manner to enhance coping abilities. Supportive care provides assurance during the acute survivor phase.
