근감소증은 노인들 사이에서 점점 더 흔하게 발생하고 있어, 최근 주목을 받고 있는 질병이다. 근감소증의 원인은 매우 다양하게 나타나지만, 노화, 식습관, 운동 부족등이 주요한 원인들 중 하나이다. 근감소증은 원인이 다양한 만큼 예방 및 치료에 전략을 개발하는 것이 중요하다. 하지만 요인이 다양한 만큼 사람이 근감소증을 정확하게 예측하기는 어렵다. 여기서 기계학습을 이용해 근감소증 예측의 정확도와 편의를 크게 높일 수 있다. 그러나 생활습관과 생체 데이터의 양은 방대한 만큼, 전처리 없이 데이터를 쓰기에는 시간복잡도와 정확성 측면에서 부적절할 수 있다. 본 논문에서는 근감소증과 그 원인에 대한 최신 문헌을 검토하고, 그에 맞게 기계학습 기만 근감소증 예측에 활용할 데이터를 전처리하는데 초점을 맞춘다.

The study analyzed the body shape perception, weight control attitude, nutrition knowledge, and dietary habits of 529 high school students in Jeju surveyed from January 14-18, 2008 according to students' body shape satisfaction, with the aim of providing basic nutritional education data to aid in appropriate weight control for high school students. The data were analyzed by descriptive analysis, T-test, Chi-square test, ANOVA, and Pearson's correlation coefficients, using the SPSS Win 12.0 program. The body mass index (BMI) of subjects was in the normal range. With regard to weight distribution, 59.4% of subjects showed normal weight and girls were significantly more underweight than boys. More girls considered themselves to be fatter than boys and tended to be increasingly dissatisfied with their body shape. Both boys and girls were more interested in weight control for obesity and were significantly less satisfied with their body shape. Efforts at weight control and reduction had occurred significantly more often for girls than for boys. Dietary attitude scores were significantly higher in girls than boys. BMI positively correlated to weight control concern and nutrition knowledge positively correlated to dietary attitude. BMI negatively correlated to the body shape satisfaction, which in turn negatively correlated to food ingestion disorders. Therefore, it is necessary to develop a systematic nutrition educational program that can induce changes in dietary behavior and increase accurate perception and satisfaction of body shape.

[Purpose] Effective nutritional intervention can help reduce the risk of nutritional problems and improve athletic performance in adolescents. The five A's (assess, advise, agree, assist, and arrange) model is widely used as the theoretical framework for advice on nutrition, smoking, drinking, and physical activity and it recommends that practitioners in primary health care promote behavior change to facilitate positive outcomes. This model has also been useful in understanding the underlying processes of behavior change. This study aimed to develop both a novel evidence-based nutritional intervention protocol, rooted in sound nutritional theory, and a customizable nutritional intervention program to support sustainable healthy eating, enhance nutrient intake, and improve athletic performance in adolescent athletes. [Methods] In this study, we adapted the 5 A's behavioral change model and motivational interview to develop a theoretical framework to help adolescent athletes change their behavior and achieve their goals. [Results] During each step of the 5 A's protocol, a customized nutritional intervention protocol was developed by nutrition experts for each of adolescent athletes. Each plan was developed to improve the eating habits of adolescent athletes through group education and counseling. All nutritional counseling sessions were designed to enable participants to apply nutritional knowledge and practical action plans to their training and competition conditions to enable each of them to achieve individual athletic goals and facilitate self-management. [Conclusion] A theoretical and evidence-based nutritional intervention protocol was developed to identify and address obstacles to healthy dietary habits in adolescent athletes. This could be used as the basis for further studies aimed at improving nutrient intake and athletic performance in adolescent athletes.

Objectives: This study was conducted to evaluate perceptions of safety and risk among Korean industrial hygienists and the change between before and after the Sewol Ferry Disaster in 2014. Two surveys with questionnaires composed of 51 questions were completed by attendees of the Korea Industrial Hygiene Association(KIHA) conference. Methods: One was conducted at the 2013 KIHA Fall Conference(N=181) and the other was from the 2014 KIHA Summer Conference(N=123). Between these two surveys was the Sewol Ferry Disaster on April 14, 2014, which was believed to seriously affect safety and risk perceptions in Korea. Results: It was revealed that industrial hygienists' awareness of safety rules strengthened after the Sewol Ferry Disaster(p<0.05). It was apparent that people over the age of 30 were more sensitive to social safety. There was no significant difference in the evaluation and attitude regarding governmental safety policy between the years of 2013 and 2014. The credibility of public organizations responsible for the disaster management system decreased. The self-evaluation of respondents' safety level also decreased. This trend shows mainly in the younger generation. It was evaluated that the overall social safety level decreased and the anxiety level increased. The score on social safety on a ±5 Likert scale was 0.68 in the 2013 survey and -0.33 in the 2014 survey(p<0.05). It was reported that the most serious threat factors for accident or disaster were 'building collapse > illegalities and corruption > side effects of radiation therapy >accidents in normal activity > occupational disease,' in order. They picked 'safety ignorance > hurry-up habits and culture > focusing on short-term benefit > easy-going attitude > insufficient safety education' for the causes of low social safety levels in 2013. In 2014, they were 'safety ignorance > easy-going attitude > focusing on short-term benefit > insufficient safety education > hurry-up habits and culture'. Conclusions: This study has some limitations because it was originally not designed to survey attitudes prior to the Sewol Ferry disaster in 2013. In addition, the survey targets are industrial hygienists who are familiar with occupational disease and injury.

This study analyzed the degree of demand for genetically modified organisms(GMOs) to provide the basic information for consumers' reasonable purchase decision making and their right to know about GMOs. Based on the (Ed-there are no study results above) study results, the following suggestion were made. First, throughout the survey, it was found that those consumers who participated had a high level of perception on the harm of GMOs. Therefore, reliable organizations such as government agencies are required to present the results of safety tests and formulate plans related to the safety of GMOs. Second, the average score on consumers' level of consumer knowledge on GMOs was very low, being 1.68 out of a possible 8 points. Third, since women and housewives engaged in dietary habits and food had high demand for information on GMOs, it is necessary to provide women with information on GMOs. Fourth, since it is difficult to confirm the presence or absence of GMOs. in rapidly increasing demand for fast-food, it is necessary that consumers be provided with relevant information and make a reasonable judgement in purchasing food. Fifth, it is necessary to provide detailed regulations and measures for concrete contents and directions of information on GMOs. Sixth, it is necessary to provid information on GMOs from the commercial sources of information that are most preferred by consumers.
