BACKGROUND/OBJECTIVES: Association between the consumption of sugar-sweetened beverages (SSBs) and obesity is universally a controversial issue. This study was undertaken to examine the beverage consumption pattern of Korean adolescents. SUBJECTS/METHODS: Data was collected from the 2016 Korea Youth Risk Behavior Survey involving 65,528 adolescent respondents. A list of the most frequently consumed beverages was analyzed, and the consumption frequency of carbonated beverages, SSBs, and energy drinks during the past seven-days was assessed. The main reasons for the adolescents to consume the beverages were also determined. RESULTS: The beverage preference of adolescents were carbonated beverages (31.0%), 'fruit and vegetable beverages (17.7%)', 'milk (13.6%)', and 'coffee (12.7%)'. Carbonated beverages and SSBs were consumed more than three times a week by 27.1% and 41.1% of the respondents, respectively. About 86.2% of adolescents did not take of any energy drinks during the last seven-days. Taste was the most common reason that adolescents considered when choosing a drink. Carbonated beverages consumed more frequently by boys than girls, and high school students drank coffee more frequently than middle school students. CONCLUSIONS: Boys had a higher preference for unhealthy beverages than girls, whereas consumption of high-caffeine drinks was greater amongst high-school students than middle school students.

A site survey was conducted on 30 parties (15 in Jeju City and 15 in Seogwipo City) concerning with the use of fishing ports in Jeju to review the appropriate conditions for selecting fishing ports as control subjects. The survey determined size of pleasure craft mooring within fishing port (20%), size of fishing boat mooring (20%), and accessibility of fishing port (20%) under on-site survey factors as well as willingness to form a consultative group between fishing boat and pleasure craft users (20%). Upon the request of the survey, positive and negative opinions were collected on the establishment of a safety control center in the fish port. Based on the survey results, the factors mentioned above were applied to each and every fishing port within Jeju. The bottom five fishing ports in Jeju with the lowest total factor scores were identified and selected as control subjects for review and study. Of the five fishing ports selected as control subjects amidst the 99 fishing ports in Jeju, Dodu Fishing Port had the lowest score of 22% among the national fishing harbors. Among the local fishing ports, Hwabuk Fishing Port had the lowest score of 18%, followed by Sagae Fishing Port with a score of 22%.

Objectives : To figure out the status of infection control (IC) in dental healthcare field and to propose the way for improvements through assessment about cognition of the clients. Methods : Study subjects were 151 patients who visited H dental health organization (DHO) of the four DHO in Busan city. The questionnaire survey performed from November 10 to December 7, 2010. Results : 1. 43.0% of consumers were interested in perception and experience in the infection control, and 38.4% were related behavioral changes in the infection control. 2. In the clients survey, the major considerations about the performance for IC were hand washing(73.5%). 3. There was significantly higher in middle-aged to think for ages infection prevention behaviors recognized as important to wear safety glasses. 4.

This study was performed to provide sources of nutrition education for female adolescents by identifying eating disorder patterns and their relationships with self-body image, weight control, and eating behavior. A total of 329 female middle school students were recruited and completed a general characteristics survey, the Eating Attitudes Test(EAT-26), a perception of self-body image survey, a concern for weight control survey, an eating behavior survey, and the Mini Dietary Assessment Index(MDA). Eating disorder patterns were identified to be obesity stress and weight control(OW), risk of binge eating(RB), and dietary restraint(DR) by factor analysis. OW pattern was related with stout body shape, body dissatisfaction, experience of weight control, skipping of dinner, and low MDA score. RB pattern was associated with lean body shape, body satisfaction, indiscreet snack behavior, and the eating time of snacks. The DR pattern was associated with normal body shape, regular meal times, desirable snack behavior, and high MDA scores. The results indicated that the eating patterns of adolescent were not identical to existing diagnostic categories. Furthermore, each eating pattern displayed different characteristics of perception on self-body image, concern for weight control, and eating behavior. In conclusion, nutrition education for female middle school students could reflect the different characteristics of each eating disorder pattern.

This study aims to offer base line data for efficient conflicts control measures by first, analyzing the current situation of the regional comprehensive development project and second, identifying level, type and cause of the conflicts appeared during the development business promotion. For this purpose, theoretical side of this study establishes a basic frame by reviewing the existing researches in order to analyze the characteristics of the conflicts between the participation subjects in the development business, and the empirical side conducts survey and analysis on the awareness on these conflicts. As a result of the analysis, the survey revealed the followings. First, the respondents were aware of the overall promotions of the business quite positively, second, the conflicts were considered as a major obstacle against the development project promotion just as the other negative factors, third, majority of the responses on the seriousness of the conflicts were neutral which meant that the conflicts could be deepened by situations, fourth, most respondents had positive recognition on the needs of conflict control training and its effectiveness, and last but not least, most respondents of the survey revealed their intentions to take parts in trouble shooting from the conflicts. Based on the results above, we were able to extract several elements to consider preparing the countermeasures for the conflicts. First, specific plan should be arranged and institutionalized in order to control the conflicts between the residents at the initial stage of the development business or even before. Second, the specific plan must lower its threshold for easy participation of the residents in that region and make the residents main body of the conflict control. Third, enhanced conflict control education must be provided to the residents of the region where comprehensive development plan is in progress or being prepared.

측량 기준점은 국민의 재산권 설정과 밀접한 연관이 있는 국가 중요시설물로 국가 또는 지자체에서 관리하고 있다. 따라서 이와 같은 측량 기준점은 측량성과는 물론 데이터베이스 및 표지의 관리에 이르기까지 중요한 국가 자료임에도 그동안 방대한 물량에 따른 인력, 시스템, 관련 제도 등 관리적 측면에서 각종 문제점들이 지속적으로 제기되어 왔다. 현재, 지자체마다 지리정보시스템이 개별적으로 구축 및 운영되고 있으나, 통합, 연계 및 활용 측면에서는 미흡한 실정이다. 따라서 본 연구에서는 지리정보시스템을 기반으로 한 측량 기준점 관련 정보 제공 및 관리를 위한 관리시스템의 기능 개선 방안과 기준점 이전 경비의 선납부제도 정착방안을 제시하였다. 이를 통해 관리자와 사용자 중심의 One-stop 기준점 관리 통합 시스템 구축의 근간을 마련하고, 기준점 망실 원인자 불명에 따른 기준점 복구비 부과 문제를 해결할 수 있을 것이다.

While the engine dynamics is, in nature, a uncertain nonlinear system, practical control methods for nonlinear systems are presently limited. This paper discusses important issues of engine control such as fuel economy, exhaust emission control, and driveability. Recent development in engine control technologies is reviewed. New control methods which appear to be useful for engine control are introduced.

Normal Operation Safety Survey (NOSS) is a safety management tool used by air traffic control organizations to measure data related to threats and errors to proactively prevent accidents before they occur. NOSS was developed to be applied to the air traffic control field according to the concept of Line Operation Safety Audit (LOSA) conducted by airlines to reduce human errors in the cockpits. Safety management based on data is crucial for the prevention of control-related accidents, and the competency of observers for this is important for the successful implementation of NOSS. Based on LOSA implementation experiences and expert interviews, this paper introduces the international NOSS methods and discusses the key factors required for effective observation and the implementation methods and implications of NOSS observer training.
