The first dental visit is recommended at the time of the eruption of the first tooth and no later than 12 months of age. However, even before the age of 1, children can visit the dental hospital for various reasons. The purpose of this study was to analyze the reasons for the dental visit of infant. From January 2006 to December 2015, medical records of infants who visited the Department of Pediatric Dentistry of Kyung Hee University were analyzed. The total number of patients was 419 (238 males and 181 females). The reasons for the dental visits were trauma (47.5%), natal/neonatal tooth (19.8%), dental caries (8.1%), teething problem (4.3%), abnormal frenum (3.6%), soft tissue swelling (3.6%), Bohn's nodule (3.3%), cleft lip and palate (2.9%), gingival neoplasm (1.9%), tongue ulceration (1.7%), oral examination (1.4%), enamel hypoplasia (1.2%) and abnormal temporomandibular joint sound (0.7%). According to this study, there were various oral diseases that could occur in infants. Since infants are usually cared by caregivers, pediatricians, and obstetricians, education of oral diseases of infants is needed to manage the oral symptoms properly.

This study aims to identify effects of welfare-to-work programs that helped welfare recipients promote emotional and social self-sufficiency, focused on social adaptation program for the hardest-to-employ poor with psychological and social work barriers. This study relied on data from mandatory social adaptation program participants among community self-sufficiency organizations in nationwide from December 2010 to January 2011 in South Korea. Hierarchical regression was used to analyze for this study. As a result, among participants, there were slightly than moderate level on emotional and social self-Sufficiency effects. The satisfaction of education program had positive effect both emotional and social self-sufficiency whereas that of health service only had positive effect on social self-sufficiency. Also, these emotional and social self-sufficiency effects differed between the number of needy family in household, type of organization and degree of satisfaction of life. This study suggests that discussion of implications for the development of welfare-to-work program and intervention that target psychological, emotional and social needs for recipients with work barriers.

To increase knowledge regarding the ecotourism market in Korea, this study conducted a market segmentation based on tourists' motivations and attitudes. An onsite survey of visitors to Daebu Haesol 1 gil, Gyeonggi Province, was conducted from late November 2016 to early January 2017. An exploratory factor analysis and K-means cluster analysis were employed to identify market segments by using data collected from 434 respondents. The results showed three distinct segments labelled 'Nature Seeking Responsible Tourists', 'Passive Nature Seeking Tourists' and 'Nature/Cohesion Seeking Responsible Tourists.' All three segments had different levels of 'escape', 'health' and 'cohesion' motivations but commonly they all had a relatively high level of 'nature' motivation. As they also differed from each other in terms of sociodemographic and travel related characteristics as well as satisfaction level, it was concluded that motivation and attitudes of responsibility can be used for ecotourism market segmentation. A significant implication is that this research confirmed that the indicators on tourists' attitude of responsibility toward local communities are useful in segmenting visitors to ecotourism sites, which have been rarely studied in previous ecotourism market studies.

The purpose of this study is to examine whether there is a difference in the awareness of death based on happiness (since attitude or way of life differs among the general public, depending on the perception of death), and to investigate whether there is a difference in the interest in hospices between a group with a high happiness index and a group with a low happiness index. A survey was conducted on 200 men and women aged over 20 who participated in a walking event held in a metropolitan city on April 22, 2017. The survey consisted of eight demographic items: gender, age, education, occupation, marital status, family cohabitation, religion, and health status. It included 29 questions regarding happiness and nine questions regarding the perception of death. For the statistical tests, a chi-square test, an independent sample t-test, correlation analysis, and canonical correlation analysis were performed on the items of the survey based on a happiness index. The results of the study showed that, for a suitable place for death, medical institutions was the highest score (46.3%) for the group with a low happiness index, and own house was highest (59.4%) for the group with a high happiness index. This was a significant difference. It is thought that management systems should be supplemented by professional manpower, educating people so as to increase the utilization rates of home-based hospice as a way for patients to die in a comfortable and familiar place because, for Korea, death is much more common in hospitals. It is also necessary to increase the awareness of death and to make effective use of hospices through individual and various other approaches, considering the demographics of the subjects.

Objectives: Corticosteroids, usually as an inhaled form, are usually used to treat narrowed airway in the treatment of asthma. However, the use of corticosteroid commonly associated with the development of osteoporosis. In this study, we studied the association of asthma and osteoporosis in the residents of the local community. Methods: As a part of the Local Community Health Study Chungnam 2008, the residents are surveyed with the formal questionnaire. We analyzed the association between asthma and osteoporosis data with the questionnaire. Results: We analyzed total 6,348 data from the residents in Chungnam province. Of them, 203(3.2%) were asthma patients and 465(7.3%) were osteoporosis patients. Patients with asthma have more advanced age(p<0.001), higher incidence of hypertension(p<0.001) and diabetes(p=0.001), lower incidence of exercise(p=0.002) and economic activity(p<0.001). Patients with osteoporosis have more advanced age (p<0.001), female predominance(p<0.001), higher incidence of hypertension (p<0.001), diabetes(p=0.001), and fractures (p<0.001), lower incidence of exercise (p=0.002) and economic activity (p<0.001). In total population, asthma is associated with the increased incidence of osteoporosis, especially in patients treated with anti-asthmatic medications. Conclusions: Through this study, we demonstrated the presence of asthma is closely associated with the increased incidence of osteoporosis, especially in patients treated with anti-asthmatic medications. Therefore, further and broad study will be needed to evaluate the association of asthma and the types of anti-asthmatic medications in the development of osteoporosis.

Aims: This study was carried out to find the prevalence of human clonorchiasis and to know epidemiological features in a Clonorchis sinensis-endemic area in Korea. Methods and materials: The EHSA was applied for the serodiagnosis of clonorchiasis. A total of 2,591 inhabitants at Soonchang-gun county adjacent to the Sumjin River were screened through the assay. The questionnaire survey was performed for several epidemiological points related to C. sinensis infection. Data from 95 inhabitants were processed for the statistical analysis. Results: The prevalence of human clonorchiasis in Soonchang-gun was 16.1% in average from 33.6% to 7.0% according to the villages of the survey. In the riverside villages to the Sumjin River the prevalences were higher than those in other villages located far from the river. The odd ratio (OR) between men and women was 2.76, indicating that the clonorchiasis was 2.76 times more prevalent in man than woman. The ORs were 2.14 in alcoholic group, 2.40 in the group of raw-eating of fresh-water fishes, 2.44 in the people who thought they were healthy, 5.23 in the people who knew well about the clonorchiasis, and 3.32 in the people who had again raw-eating of the fishes following medication. Conclusions: These results suggested that human clonorchiasis was still highly endemic in riverside area of the Sumjin River and some predisposing factors such as raw-eating of fresh-water fishes were significantly related to the human clonorchiasis.

The aim of this study is to investigate the optimal algorithm to extract medical radiation induced pixel signal from complementary metal-oxide semiconductor (CMOS) sensors of smartphones camera. The pixel intensity and pixel number of smartphone camera were measured as the X-ray dose was increased. The front camera of the smartphone camera has low noise property and excellent dose response as compared to the back camera of the smartphone. The indirect method which uses scintillation crystal in front of the smartphone camera, couldn't improve the X-ray detection efficiency as compared to the direct method which does not use any scintillator in front of the smartphone camera. When we used the algorithm which employing threshold level on the pixel intensity and pixel number, the dose linearity was more higher for the pixel intensity rather for the pixel number. The use of pixel intensity of Y color component which represents the grey scale, would be efficient in terms of the radiation detection efficiency and reducing the complexity of the image processing. We expect that the radiation dose monitoring can be managed effectively and systematically by using the proposed radiation detection algorithm, thus eventually will contribute to the public healthcare.

수자원 분야에서 가장 기본적이면서 중요한 과업 중의 하나는 고품질의 유량측정 자료를 확보하여 신뢰성 있는 수위-유량관계곡선식을 개발하는 것이다. 이는 수공구조물 설계, 친수 하천공간 조성, 친환경적인 하천의 설계, 하천 관리수량 산정, 홍수 예 경보 운영 등에 기본적인 자료를 제공하게 된다. 신뢰성 있는 곡선식은 계측장비의 개량과 유량관측 기준의 강화 등을 통하여 축적된 양질의 유량측정 자료로부터 개발될 수 있으며, 또한 수위관측소 지점의 하도특성과 통제구조물의 특성 등을 고려하는 것도 곡선식의 신뢰도를 높일 수 있다. 본 연구는 통제단면의 가장 낮은 부분의 수위로 정의되는 흐름이 0인 수위인 GZF(Gauge Height of Zero Flow) 평가에 관한 연구이다. 이와 같은 연구를 수행하기 위해서 GZF의 변화에 따라 곡선식의 신뢰도를 분석할 수 있는 시스템을 개발하였으며, 이 시스템은 사용자들이 쉽게 이용할 수 있는 엑셀 VBA(Visual Basic for Applications)를 이용하여 개발하였다. GZF 평가 시스템은 입력자료 구축 모듈, 수위관측소 지점의 하도 단면 입력 모듈, GZF 설정 모듈, GZF 평가 모듈의 4개 모듈로 구성되었다. 입력자료 구축 모듈은 기 개발된 곡선식의 GZF 적정성을 파악할 수 있도록 자료를 구축하는 모듈이며, 하도 단면 입력 모듈은 수위관측소 지점의 하상의 변화 유무와 구간분리, 기간분리 등의 필요성을 파악할 수 있도록 구성하였다. GZF 설정 모듈은 GZF의 변화가 곡선식의 신뢰도를 파악할 수 있도록 구성되었다. 마지막으로 GZF 평가 모듈은 기 개발된 곡선식의 GZF와 금회 개발될 곡선식의 GZF를 비교 분석할 수 있도록 구성되었다. 본 연구의 성과는 향후 수위-유량관계곡선식을 개발할 때 GZF 산정의 오류를 감소시켜 앞으로 개발될 곡선식의 신뢰도 향상에 기여를 할 것으로 판단된다.소를 파악해야한다. 7. 부아 유대에 대한 위협요소 확인을 위한 도구개발과 그들에 대한 효과적인 간호전략이 필요 된다. 8. 가족에 있어서 모든 부모행위가 하나의 독립변수로서 연구되어야 하고 부아유대 증진에 관한 연구가 시도되어야겠다. 오늘날 부모들은 임신기간동안 많은 정보에 접하기를 원한다. 산전, 산후의 교육과 지식은 긍정적인 부아 관계를 증진시키고, 이것은 아동의 발달에 크게 기여할 수 있다. 긍정적으로 이러한 관계는 가족단위를 강하게 통합시키게 되므로 건강관리자(Health care workers)들은 애착에 대해 높은 관심을 갖어야 하겠다.2유수지는 BTL사업을 통해 주변공단으로부터의 오폐수를 원천적으로 차단하도록 하였으며 2유수지를 매립하여 지하는 강우시 유출수 저류가 가능한 화물차주차장으로 활용하고 지상은 녹지공간으로 조성하여 공단근로자 및 지역주민을 위한 휴식공간으로 활용될 수 있도록 제안하였다. 본 연구는 남동유수지 환경 개선 사업 실행을 위한 정책 연구로 연구결과를 인천시가 적극 수용하기로 결정함에 따라 인천시의 환경 현안 문제인 남동유수지의 수질개선을 통해 시민의 휴식 및 여가선용 공간으로 활용하기 위한 사업의 기초자료로 활용되며 이미 설계검토가 시작되었다. 본 연구결과는 유수지 및 저수지의 환경개선 사업의 선두적인 성공사례로 국내 타 지역의 유사한 사업에 있어 벤치마킹을 할 수 있는 훌륭한 사례가 될 것이다.요 생산이 증가하자 군신의 변별(辨別)과 사치를 이유로 강력하게 규제하여 백자의 확대와 발전에 걸림돌이 되었다. 둘째, 동기(銅器)의 대체품으로 자기를 만들어 충당해야할 강제성 당위성 상실로 인한 자기수요 감소를 초래하였을 것으로 사료된다. 셋째, 경기도 광주에서 백자관요가 운영되었으므로 지방인 상주지역에도 더 이상 백자를 조달받을 필요가 없이, 일반 지방관아와 서민들의 일상용기 생산으로 전락하여 소규모화 되었을 것이라고 사료

Stream ecosystems are highly valued natural resources, however, stream environments are currently under threat in several respects. We evaluated vegetation and ecological characteristics according to different revetment types. The distribution of vegetation differed with revetment type, with a 42~45 taxa found in natural revetments, and 23~38 taxa in vertical revetments. Thus, natural revetments host more diverse vegetation than vertical revetments. We also found more plants belonging to the families Labiatae and Cyperaceae growing in natural revetments than in vertical revetments. We proposed that habitat space be apportioned to introduce annual plants as part of stream restoration projects. And, we identified 7 families and 18 taxa of naturalized plants, majority taxa were either biennial or perennial. Moreover, naturalized ratio was higher in vertical(14.3%) than natural(12.1%), we proposed a plan to promote and improve natural streams and revetments. Furthermore, we applied a waterfront evaluation method developed by the Natural Resources Conservation Service of the USDA-NRCS, which confirmed that stream health can be improved in most regions by controlling naturalized plants and ensuring shrub and tree growth. We adopted a new method to remove naturalized plants and establish natural revetments to ensure shrub and tree growth to aid in small-stream restoration and improvement. In future studies, we hope to develop methods for small-stream restoration projects in rural areas.
