Objective: Despite government efforts to increase participation in gastric cancer screening, the rate is still suboptimal in Korea. Therefore, we explored barriers to and predictors of gastric cancer screening participation among a nationally representative sample. Methods: We used the Health Interview Survey sub-dataset derived from the Fourth Korean National Health and Nutrition Examination Survey 2008 (KNHANES IV) to evaluate participation in gastric cancer screening and factors associated with attendance in individuals age ${\geq}40$ years. We enrolled 4,464 subjects who completed the questionnaire and were not previously diagnosed with gastric cancer. Four groups of factors were considered potential predictors of gastric cancer screening in a multivariate analysis: sociodemographic, health behavior, psychological and cognitive, and dietary factors. Results: Overall, 41.3% complied with the gastric cancer screening recommendations. Younger age, lower education level, living without a spouse, frequent binge drinker, and current smoker were significantly associated with less participation in gastric cancer screening. Conclusions: To improve participation in gastric cancer screening, more focused interventions should be directed to vulnerable populations, such as groups with low socioeconomic status or unhealthy behavior. In addition, there should be new promotional campaigns and health education to provide information targeting these vulnerable populations.

For fishery stock assessment and optimum sustainable yield of anchovy in Korea, surplus production(SP) models and a maximum entropy(ME) model are employed in this paper. For determining appropriate models, five traditional SP models-Schaefer model, Schnute model, Walters and Hilborn model, Fox model, and Clarke, Yoshimoto and Pooley (CYP) model- are tested for effort and catch data of anchovy that occupies 7% in the total fisheries landings of Korea. Only CYP model of five SP models fits statistically significant at the 10% level. Estimated intrinsic growth rates are similar in both CYP and ME models, while environmental carrying capacity of the ME model is quite greater than that of the CYP model. In addition, the estimated maximum sustainable yield(MSY), 213,287 tons in the ME model is slightly higher than that of CYP model (198,364 tons). Biomass for MSY in the ME model, however, is calculated 651,000 tons which is considerably greater than that of the CYP model (322,881 tons). It is meaningful in that two models are compared for noting some implications about any significant difference of stock assessment and their potential strength and weakness.

Hazard Analysis and Critical Control Points (HACCP) is a systematic preventative approach for food safety and is generally used in food industry to identify potential food safety hazards. Recently, the Korean Ministry for Food, Agriculture, Forestry and Fisheries planed to applicate HACCP programs as an effective approach to food safety and protecting public health at the aquaculture farm of rainbow trout, Oncorhynchus mykiss. For the purpose, it need to identify what kinds of hazards are in the aquaculture farm. In the present study, we established Sanitation Standard Operating Procedures (SSOP), which addresses sanitation conditions and practices in the aquaculture farm. SSOP is essential prerequisite programs of HACCP to reduce or eliminate the risk of the hazards being realized. We anticipate that the HACCP programs of aquaculture farm will contribute to supply foods in safety to consumers.

The egg Positive rate of Enterobius vermicularis and Clonorchis sinensis of school children in the rural area was studied in Hamyang-gun, Gyeongsangnam-do in Korea. Cellotape anal swab and formalin ether concentration methods were performed one time to 720 Primary school children. The total egg Positive rate of E. vermicularis was 12.6% in two schools (Baekjeon and Wiseong). In the Baekjeon and Wiseong primary school, the egg Positive rate of E. vermicularis was 4.6% and 13.4%, respectively Pinworm egg Positive rate was 17.6% in the lower grades (1st, 2nd and 3rd), and 7.7% in higher grades (4th, 5th and 6th). The total egg Positive rate of male and female was 12.6% and 12.7%, respectively. The egg Positive rate of C. sinensis of Baekjeon and Wiseong Primary school was 1.5% and 0.46%, respectively The total e99 Positive rate of C. sinesis was 0.56%. This survey showed that continuous education and chemotherapy is necessary to treat and prevent reinfection of E. vermicularis. In the case of C. sinensis, health education for school children is recommended to prevent potential infection of adolescents.

As a dental technician, the aim of the present study on maxillofacial prosthesis was to research its relation with dental technology and further development aspects by looking into its history, kinds, production materials and process. Dental technicians are to expect a great potential to work as maxillofacial prosthetist if having an interest in education of maxillofacial prosthesis field, and developing and operating the education process by expanding the range of dental technology. This article is to present overall history of maxillofacial prosthesis and some background information on the materials which have been used from the past. The maxillofacial field plays essential functions of mastication and speech, as well as performs appearance, which evokes good or bad feelings as an instant and instinctive response. The use of maxillofacial prostheses is not merely the replacement of a missing part of the face, resulted from injuries, but a rehabilitation process to help individuals come back to society. Rehabilitation includes both patient's physical and psychological recovery, such as self-esteem and selfconfidence. There has been a rapid development in application potentials of maxillofacial prosthesis technology which include implant, which can penetrate skin, and new materials. In order to produce maxillofacial prosthesis, general procedures of maxillofacial laboratory work should be understood first. Maxillofacial prosthesis and the dental prosthesis have many similarities in its academic perspective and originality. Maxillofacial prosthesis should be added into the curriculum for dental technology to achieve co-enhancement of the two fields.

Even though many researchers have reported that everyday contexts can arouse students' interests and improve their science learning, the connection between everyday context and physics learning is not yet clearly discussed. In our study, at first, we assumed five guidelines for helping the development of teaching materials for physics learning in everyday context. Based on these guidelines, we developed teaching materials for understanding basic optics and applied these materials to ninth grade students. From the positive responses of students and science teachers about the developed materials, we could confirm that the guidelines were reflected well in the materials. And also, it was found that students and teachers wanted to learn or teach context-based physics in future classroom learning. However, all students do not receive benefits from learning physics in everyday context. By analyzing students' actual learning processes and interviews with them, we found five potential impeding factors which could hinder students' successful learning of physics in everyday context. As a result, we suggested five recommendations for overcoming these impeding factors.

Purpose: Depression is a common sign of suffering among the patients with Parkinson's disease (PD). Frequent and severe neuropsychiatric symptoms lead to high levels of distress in patients and their caregivers, which results in the high levels of caregiver burden. The aim of this study was to determine the predictors of caregiver burden in caregivers of the patients with Parkinson's disease (PD). Methods: The study included 183 consecutive PD patients and their caregivers. Patients were assessed using the Hoehn and Yahr scale, Mini Mental State Examination (MMSE), Beck Depression Inventory (BDI), and Schwab and England Activities of Daily Living Scale. Caregivers' depressive symptoms were evaluated using the Caregiver Burden Inventor (CBI), BDI, and World Health Organization Quality of Life Scale. Results: All of the patients reported one or more neuropsychiatric symptoms. Patients' and caregivers' depressive symptoms, caregivers' age and education, time for caregiving, and quality of life were significantly associated with the increased caregiver burden. After controlling the level of education as a potential confounding variable, depression in both patients and caregivers, time for caregiving, and quality of life explained 45.6% of the variance in caregiver burden. Conclusion: Substantial attention needs to be given to the early identification of depression in PD patients and their caregivers to improve caregivers' quality of life and burden.
