  • 무선 센서 네트워크에는 한정된 배터리 자원과 네트워크의 라이프타임(lifetime)으로 인해 멀티레벨 커버리지 문제가 이슈가 되어 왔다. 하지만, 대부분의 연구에서는 멀티레벨 커버리지 문제를 해결할 때 센싱 범위는 고정적이며 변경할 수 없음을 가정하고 있으며, 이로 인해 센싱 범위와 커버리지 범위와의 관계에 대해서 고려하고 않고 있다. 본 연구에서는 센싱 범위와 커버리지 범위와의 관계를 이용하여 유동 센싱 범위(DSR, Dynamic Sensing Range) 배치에 대하여 연구하였다.

  • Purpose: This study aimed to investigate inequalities in colorectal cancer (CRC) screening rates in Korea and trends therein using the slope index of inequality (SII) and relative index of inequality (RII) across income and education groups. Materials and Methods: Data from the Korean National Cancer Screening Survey, an annually conducted, nationwide cross-sectional survey, were utilized. A total of 17174 men and women aged 50 to 74 years were included for analysis. Prior experience with CRC screening was defined as having either a fecal occult blood test within the past year or a lifetime colonoscopy. CRC screening rates and annual percentage changes (APCs) were evaluated. Then, SII and RII were calculated to assess inequality in CRC screening for each survey year. Results: CRC screening rates increased from 23.4% in 2005 to 50.9% in 2015 (APC, 7.8%; 95% CI, 6.0 to 9.6). Upward trends in CRC screening rates were observed for all age, education, and household income groups. Education inequalities were noted in 2009, 2014, and overall pooled estimates in both indices. Income inequalities were inconsistent among survey years, and overall estimates did not reach statistical significance. Conclusion: Education inequalities in CRC screening among men and women aged 50 to 74 years were observed in Korea. No apparent pattern, however, was found for income inequalities. Further studies are needed to thoroughly outline socio-economic inequalities in CRC screening.

  • Background: Chemical emissions in the environment have rapidly increased with the accelerated industrialization taking place in recent decades. Residents of industrial complexes are concerned about the health risks posed by chemical exposure. Objectives: This study was performed to suggest modeling methods that take into account multimedia and multi-pathways in human exposure and risk assessment. Methods: The concentration of benzene emitted at industrial complexes in Daesan, South Korea and the exposure of local residents was estimated using the Caltox model. The amount of human exposure based on inhalation rate was stochastically predicted for various activity stages such as resting, normal walking, and fast walking. Results: The coefficient of determination (R2) for the CalTOX model efficiency was 0.9676 and the root-mean-square error (RMSE) was 0.0035, indicating good agreement between predictions and measurements. However, the efficiency index (EI) appeared to be a negative value at -1094.4997. This can be explained as the atmospheric concentration being calculated only from the emissions from industrial facilities in the study area. In the human exposure assessment, the higher the inhalation rate percentile value, the higher the inhalation rate and lifetime average daily dose (LADD) at each activity step. Conclusions: Prediction using the Caltox model might be appropriate for comparing with actual measurements. The LADD of females was higher ratio with an increase in inhalation rate than those of males. This finding would imply that females may be more susceptible to benzene as their inhalation rate increases.

  • Nutrition education should be an important component of ongoing health promotion for older adults and their caregivers. This is because prevention through sound nutrition and food hygiene practices and regular excercise is the most cost-effective way to reduce risks for and deal with their major health problems. nutritions education services should effectively promote optimum intake and successful self-care. Unfortunately, however relative to other vulnerable groups, nutrition education for older adults has not been systematically developed or evaluated. Usually oder adults care a lot about their health, so this should be a relatively easy group to teach - but their increasing numbers, longevity and great diversity with respect to health, physical, and economic status and educational level present challenges. Some older adults may not perceive they would benefit from nutrition education, so interesting and motivating them is a challenge. The food and nutrition knowledge of older people has been acquired through a lifetime of experience. For most older adults in the Asian region, their sources are restricted by their restricted education, so that their major sources of information have been informal sources, such as television, radio, friends, family, and perhaps newspapers and magazines if they are literature. Nonetheless, dietary advice for older people should build on their existing knowledge and ingrained values. It should provide information useful in daily food selection, and focus on food, not nutrients - the same foods and groups considered appropriate for younger people, with consistent messages as given throughout the population. Attention must also be paid to discovering learning styles in older people. When we teach in schools, the young students are a captive audience resigned to their learning role. Learning by an older adult, however, reflects an effort to meet his or her perceived needs. Therefore, nutrition education should be a positive experience in a non-threatening environment, relaxed and non-competitive, and perhaps even social environment. The messages also need to be practical and achievable. A needs assessment is essential, because our ability to provide the most effective nutrition education will depend on our success in matching the needs, both perceived and unperceived. of this vulnerable group. Therefore, go to the potential older learners to assess their interest and preferences. Nutrition education activities for older adults are widespread, but few have been evaluated. Evaluation is therefore also recommended, particularly when new methods are used. Tips from other countries for giving successful nutrition education will be given, including some examples of applications as attempted in Hong Kong. Research needs will also be described. In conclusion, successful nutrition education for older adults depends on positive needs-based messages. This is may be hard to do, as few good examples are available to illustrate these principles.

  • The Korean Astronomical Society (KAS) Education & Public Outreach Committee has provided education services for children and school teachers in Cambodia over the past three years from 2016 to 2018. In the first year, 2016, one KAS member visited Pusat to teach astronomy to about 50 children, and in the following two years of 2017 and 2018, three and six KAS members, respectively, executed education workshops for ~ 20 (per each year) local school teachers in Sisophon. It turned out that it is desirable to include both teaching of astronomical knowledge and making experiments and observations in the education in order for the program to be more effective. Language barrier was the main obstacle in conveying concepts and knowledge, and having a good interpreter was very important. It happens that some languages, such as the Khmer of Cambodia, do not have astronomical terminologies, so that lecturers and even the education participants together are needed to communicate and create appropriate words. Handout hard-copies of the education materials (presentation files, lecture/experiment summaries, terminologies, etc.) are extremely helpful for the participants. Actual performing of assembling and using astronomical telescopes for night sky observations has been lifetime experience for some of the participants, which might promote zeal for knowledge and education. It is hoped that these education services for developing countries like Cambodia can be regularly continued in the future, and further extended to other countries such as Laos and Myanmar.

  • 본 논문에서는 노드의 위치 정보와 유효성 경로에 따라 클러스터링내의 헤드 노드를 선출하는 방법 중 하나로 에너지 효율성을 고려한 ECOPS(Energy Conserving Optimal path Schedule) 알고리즘을 제안한다. 기존 LEACH 알고리즘은 헤드 노드를 선출할 때 노드의 에너지 확률적 분포 함수에 기반 하여 헤드 노드의 주기를 선택적으로 관리하게 된다. 그러나 이 경우 중계노드의 거리 정보 등 상황 정보 인자가 반영되지 않아 위치적으로 또는 중계노드로 적당하지 않은 노드들이 확률분포에 포함되어 헤드노드로 선택 되는 경우가 발생한다. 따라서 본 논문에서는 기존의 LEACH 기반에서 계층적인 클러스터 구조의 토폴로지로부터 헤드 노드를 선택함에 있어 인접한 노드와의 위치상황 정보인자 및 잔존에너지의 상황정보를 이용하는 ECOPS 알고리즘을 제안 한다. 제안된 ECOPS 알고리즘은 헤드 노드 교체 상황에서 후보 헤드노드 중 최적의 효율적인 에너지 보존 경로를 가지는 멤버 노드가 새로운 헤드 노드로 선출됨으로써 전체 노드 수명 및 네트워크의 관리를 향상시키는 것으로 모의실험 결과를 나타내었다.

  • Objectives: The purpose of this study is to analyze how the different lifestyles between Koreans and Korean Americans have significant effects on their health. Despite being the same race, Koreans and Korean Americans have different health conditions and health attitudes due to the acquired environmental factors such as social-economic factors, lifestyle risk factors, healthcare systems, and medical utilization. It is crucial to examine how the different lifestyle habits between Koreans and Korean Americans lead to various health conditions for establishing an effective health promotion policy. Methods: In this study, a comparative analysis was conducted using the National Health and Nutrition Survey of Korea and CHIS data of the United States in 2005 and 2015 to provide valuable insights when establishing such a policy. Results: The specific research purpose is as follows: First, socioeconomic factors, such as (1)living habits risk factors, (2)health satisfaction levels, (3)disease outbreaks, and (4)medical uses, are analyzed to find the distinct characteristics among Koreans, Korean Americans, and Americans. Second, the three groups --Koreans, Korean Americans, and Americans-- were compared based on their exposure to disease-related lifestyle risk factors related to their body mass index and their general health condition. The research results are as follows: First, all three groups improved health conditions in 2015 better than in 2005. Koreans maintained relatively higher general health conditions compared to other groups: their prevalence rate of chronic diseases such as diabetes, high blood pressure, heart disease, and asthma was lower than that of U.S. residents. Second, in regards to health behavior factors, the lifetime smoking experience for Koreans and Americans both decreased in 2015 compared to 2005, while the lifetime smoking experience for Korean Americans increased slightly. The number of smokers for Koreans has greatly decreased over a decade while that of Americans has moderately increased. Third, according to the results of the multiple regression, the general health conditions, which is a dependent variable, suggests that the number of men who answered they are healthy is greater than that of women in Korea, compared to the United States. Conclusions: In conclusion, the acquired environmental factors had more significant impacts on health than the racial factors did. Compared to 2005, the health behaviors and health levels of Korean Americans in 2015 gradually became more similar to those of Americans.

  • The purpose of this study was to provide fundamental information for success factors of techniques through kinematic analysis including coordination of lower extremities and landing stability according to the success and failure of $540^{\circ}$ Dwihuryeochagi in Taekwondo. Twenty Taekwondo athletes: ten success group (S, age: $22.3{\pm}1.8$ yrs, height: $172.1{\pm}5.4$ cm, body mass: $64.4{\pm}4.2$ kg) and ten failure group (F, age: $22.3{\pm}1.8$ yrs, height: $172.1{\pm}5.4$ cm, body mass: $64.4{\pm}4.2$ kg) participated in this study. Three-dimensional motion analysis using a system of 3 video cameras with a sampling of 60 fields/s was performed during the competition of $540^{\circ}$ Dwihuryeochagi. Motions were divided into five events: pivot foot landing (E1), pivot foot toe off (E2), COM max height (E3), kick impact (E4) and landing (E5). At E1, the stride width was greater for S than for F (p<.05) while the time was greater for S than for F during P4 (p<.05). At E4, knee angle was greater for S than for F (p<.05). At E5, hip angle was greater for S than for F (p<.05) while kick distance was greater for S than for F (p<.05). Furthermore, at P3, the time would be related to kicking velocity (p<.05), while at P4, the time, range of hip angle and knee angle would be related to kick distance (p<.05). At P1, COM horizontal velocity would be related to COM vertical velocity of P1 and P2 (p<.05). Based on the findings, success factors of $540^{\circ}\acute{y}$ Dwihuryeochagi were COM horizontal velocity of P1, COM vertical velocity of P2, the time, kick distance, velocity, angle of lower extremities and coordination of P3-P4.

  • This research was conducted to understand and analyze the health-related behaviors of middle school students and get fundamental research data essential to provide efficient student guidance and public health service at school. The interview using Youth Risk Behavior Surveillance System(YRBSS). Translation and modification for Korean students of the YRBS. The Korean version of YRBS(Youth Risk Behavior Surveillance System) that translation and modification for Korean students of the YRBS developed by the Centers for Disease Control and Prevention(CDC)was used to assessment to health-related behaviors of youth. The interviewees were 1040 enrolled students at middle school in Daegu metropolitan city. YRBSS monitors six categories of priority health behaviors among youth and young adults behaviors that contribute to unintentional and intentional injuries; tobacco use; alcohol and other drug use, sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases(STDs)(including human immunodeficiency virus infection); unhealthy dietary behaviors; and physical activity. The result shows that over 30% of students rarely or never used safety belt and almost students were rarely or never wore a bicycle helmet. During the 12 months preceding the survey, 21.9% female students had felt so sad or hopeless almost every day for $\geq$ 2weeks in a row that they stopped doing some usually activities 20.5% of male middle school students have ever tried cigarette smoking. 26.2% of male students and 27.2% do female students had had over one drinks of alcohol during their lifetime(lifetime alcohol use). 47% of male students had had over one drinks of alcohol on $\geq$ 1 of the 30 days preceding the survey(current alcohol use). Over one half of female student were thought they were overweight. These results suggest that some risk behaviors be very prevalent in a korean middle school students and priority health-risk behaviors, which contribute to the leading cause of mortality and morbidity among youth and adult, often are establish during middle school age, extend into adulthood, are interrelated. Among both children and adults, the leading causes of death are closely linked to these behaviors. Among adults, chronic diseases such as cardiovascular disease, cancer, and diabetes are the national leading killers. Practicing healthy behaviors, such as eating low-fat, high-fruit-and-vegetable diets, getting regular physical activity, and refraining from tobacco use, would prevent many premature deaths. Because health-related behaviors are usually established in childhood, positive choices need to be promoted before damaging behaviors are initiated or become ingrained.
