This paper focuses on the impacts of waste dumping on inorganic nutrients in the dumping area of the Yellow Sea, and the effect of an governmental regulation of pollution in dumping areas. The environmental variables and parameters of the dumping and reference areas in the Yellow Sea were measured during July 2009 and analyzed. In addition, the analyzed data for inorganic nutrients over the last 10 years were obtained from the Korea Coast Guard (KCG) and the National Fisheries Research and Development Institute (NFRDI). The chemical environment of the study area revealed increases in concentrations of inorganic nutrients, Chemical Oxygen Demand (COD), and Volatile Suspended Solids (VSS) in the bottom layer. On the contrary, the pH level was decreased. Most notably, the time series data of inorganic nutrients showed gradual increase over time in the dumping area, and thus, the oligotrophic waters trend toward eutrophic waters. The increases appears to be due to the disposal of large amounts of organic waste. In recent times, the wastes disposed at the area were largely comprised of livestock wastewater, and food processing waste water. The liquefied waste, which contains an abundance of nutrients, causes a sharp increase in concentrations of inorganic nitrogen in the dumping area. On the one hand, the dumping sites have been deteriorated to such an extent that pollution has become a social problem. Consequentially, the government had a regulatory policy for improvement of marine environmental since 2007 in the dumping area. Hence, the quality of marine water in the dumping site has improved.

Background: Breast cancer accounted for almost 25% of all cancers in women globally in 2012. Although breast cancer is the most prevalent cancer in India, there is no organised national breast cancer screening programme. Local studies on the burden of breast cancer are essential to develop effective context-specific strategies for an early detection breast cancer programme, considering the cultural and ethnic heterogeneity in India. This study examined the knowledge, attitudes, and practices about breast cancer in rural women in Central India. Materials and Methods: This community-based cross sectional study was conducted in Wardha district, located in Maharashtra state in Central India in 2013. The sample included 1000 women (609 rural, 391 urban) aged 13-50 years, selected as representative from each of the eight development blocks in the district, using stratified cluster sampling. Trained social workers interviewed women and collected demographic and socio-economic data. The instrument also assessed respondents' knowledge about breast cancer and its symptoms, risks, methods of screening, diagnosis and treatment, as well as their attitudes towards breast cancer and selfreported practices of breast cancer screening. Chi-square and t-test were applied to assess differences in the levels of knowledge, attitude, and practice (the outcome variables) between urban and rural respondents. Multivariable linear regression was conducted to analyse the relationship between socio-demographic factors and the outcome variables. Results: While about two-thirds of rural and urban women were aware of breast cancer, less than 7% in rural and urban areas had heard about breast self-examination. Knowledge about breast cancer, its symptoms, risk factors, diagnostic modalities, and treatment was similarly poor in both rural and urban women. Urban women demonstrated more positive attitudes towards breast cancer screening practices than their rural counterparts. Better knowledge of breast cancer symptoms, risk factors, diagnosis, and treatment correlated significantly with older age, higher levels of education, and being office workers or in business. Conclusions: Women in rural Central India have poor knowledge about breast cancer, its symptoms and risk factors. Breast self-examination is hardly practiced, though the willingness to learn is high. Positive attitudes towards screening provide an opportunity to promote breast self-examination.

Objectives: This study was performed to identify the current barriers of obesity management for children using Community Child Care Centers and their caregivers (parents and teachers working in the Centers). Further, this study explored the possibility of utilizing a mobile phone application for tailored obesity prevention and management programs to overcome the current difficulties associated with children's obesity management. Methods: The qualitative data were collected through in-depth interviews with 20 obese and overweight children or children who wanted to participate in this study using Community Child Care Centers, 12 teachers working at the Centers, and a focus group interview with five parents of children using the Centers. Data were analyzed with a thematic approach categorizing themes and sub-themes based on the transcripts. Results: The current barriers of obesity management of obese and overweight children using Community Child Care Centers were lack of self-directed motivation regarding obesity management (chronic obesity-induced lifestyles and reduced self-confidence due to stigma) and lack of support from households and Community Child Care Centers (latchkey child, inconsistency in dietary guidance between the Center and household, repetitive pressure to eat, and absence of regular nutrition education). Mobile phone applications may have potential to overcome the current barriers by providing handy and interesting obesity management based on visual media (real-time tracking of lifestyles using behavior records and social support using gamification), environmental support (supplementation of parental care and network-based education between the Community Child Care Center and household), and individualized intervention (encouragement of tailored and gradual changes in eating habits and tailored goal setting). It is predicted that the real-time mobile phone program will provide information for improving nutritional knowledge and behavioral skills as well as lead to sustainable children's coping strategies regarding obesity management. In addition, it is expected that environmental factors may be improved by network-based education between the Community Child Care Centers and households using the characteristics of mobile phones, which are free from space and time constraints. Conclusions: The tailored education program for children using Community Child Care Centers based on mobile phones may prevent and reduce childhood obesity by overcoming the current barriers of obesity management for children, providing environmental and individualized support to promote healthy lifestyles and quality of life in the future.

이 논문에서는 비접근 지역의 작물 분류를 목적으로 준감독 학습에 인접 화소의 공간 유사성 정보를 결합하는 분류 방법론을 제안하였다. 적은 수의 훈련 자료를 이용한 초기 분류 결과로부터 신뢰성 높은 훈련 자료의 추출을 위해 준감독 학습 기반의 반복 분류를 적용하였으며, 새롭게 훈련 자료 추출시 인접한 화소의 분류 항목을 고려함으로써 불확실성이 낮은 훈련 자료를 추출하고자 하였다. 북한 대홍단에서 수집된 다중시기 Landsat-8 OLI 영상을 이용한 밭작물 구분의 사례 연구를 통해 제안된 분류 방법론의 적용 가능성을 검토하였다. 사례 연구 결과, 초기 분류 결과에서 나타난 작물과 산림의 오분류와 고립된 화소가 제안 분류 방법론에서 완화되었다. 또한 인접 화소의 분류 결과를 고려한 훈련 자료 추출을 통해 이러한 오분류 완화 효과가 더욱 두드러지게 나타났으며, 초기 분류 결과와 기존 준감독 학습에 비해 고립된 화소도 감소되었다. 따라서 비접근 지역으로 인해 훈련 자료의 확보가 어려울 경우 이 연구에서 제안된 방법론이 작물 분류에 유용하게 적용될 수 있을 것으로 기대된다.

행동경제학은(Behavior Economics)은 인간이 합리적인 의사결정을 한다고 가정하는 전통경제학을 부정하고, 경제학에 심리학 기반의 인지적 원리를 적용하여 개인의 의사결정이 어떻게 이루어지는지 설명하기 위해 발전해 왔다. 개인은 의사결정에 있어서 효용을 극대화하기 위한 정보와 시간이 부족하며, 정보를 처리하기 위한 인지적 능력에도 한계가 있다. 따라서 인간의 합리성이란 제한된 합리성일 수밖에 없다. 제한된 합리성으로 인해 인간은 최선의 선택을 하지 못하고 자신이 충분하다고 생각하는 만족할 만한 수준에서 사고를 멈추고 단순한 모형이나 대략적인 추측에 의존하여 의사결정을 하게 된다. 이 단순화되는 의사결정 과정에 작용하는 것이 바로 휴리스틱(Heuristic)이다. 휴리스틱은 기존 경험이나 특정 정보만을 이용하기 때문에 의사결정이나 행동에 편향(Bias)이 생기게 된다. 구비문학은 언어 대중의 어림짐작과 사고의 편향성에 기반을 두고 전승되어 온 특징이 있기에, 행동경제학의 휴리스틱과 편향의 개념을 구비문학에 접합해 논의할 여지는 충분하다. 이 글은 대중의 사고유형과 행동양식을 단문으로 표현한 속담, 민속적인 언어 놀이인 수수께끼를 휴리스틱에 기반한 편향의 관점에서 논의했다. 그 결과 속담은 인간 행동에서 드러나는 편향의 문제점을 지적하는 측면이 강했던 반면, 수수께끼는 편향을 적극적으로 이용하는 면이 더 우세한 것을 알 수 있었다.

Objectives: This study evaluated the virucidal efficacy against avian influenza virus (AIV) of a disinfectant spray containing 0.25% grapefruit seed extract, 0.2% citric acid, 0.0625% malic acid and 0.0125% benzalkonium chloride. Methods: The disinfectant spray was diluted several times with hard water (HW) and organic matter (OM). Two point five mL of each diluent was added into each test tube, and 2.5 mL of AIV suspension was inserted into each test tube. After 30 minutes of virus-disinfectant contact reaction at $4^{\circ}C$, 2.5 mL of 10% inactivated fetal bovine serum was added into each test tube to neutralize the sanitizer efficacy. The neutralized solutions were serial 10-fold dilutions with phosphate buffer solution, and 0.2 mL of the diluents was injected into the allantoic cavity of five ten-day-old-chickens per dilution time. After incubation of the embryos for five days, the viability of the AIV was examined by hemagglutination titer. The valid dilution of the disinfectant spray was estimated according to the dilution time that the virus titer was inactivated more than $10^4$ 50% egg-infective dose (EID50)/mL compared with pathogen control. Results: In HW and OM conditions, the valid dilutions of the disinfectant spray against AIV were seven- and three-fold dilutions, respectively. The AIV titer of the pathogen control was more than 6.1 log10EID50/mL, and there was no embryonic toxicity. Conclusion: The present study showed that this disinfectant spray has effective virucidal activity against AIV.
