The tidal flat area of south and west coast consists of 2.4% of total land area of Korea. About 83% of tidal flat is located at the west coast, and the remaining tidal flat is located at the south coast. This tidal flat is also divided for administrative regions which are Gyeonggi Province(35.1%), Chungnam Province(12.7%) Jeonbuk Province(4.7%), Jeonnam Province(44.0%) and Gyeongnam Province(3.5%). The tidal flat of west coast of Korea is one of the most important stopover site for shorebirds on the East Asia-Australia Flyway. The tidal flat is used for feeding and resting place by migratory shorebirds. Generally, waterbirds including migratory shorebirds are considered as key species to show the superiority of wetland. By the criteria of Lamsar Convention in the basis of waterbird, at least 14 coastal wetlands in Korea have to be internationally important wetlands. The factors to affect the distribution of shorebirds at the certain tidal flat are closely related with 1) the distribution of benthic invertebrates, potential prey of shorebirds 2) the availability of roosting site 3) the size of tidal flat 4) the intensity of human disturbance. In this paper, we summarized the regional status of tidal flat of Korea and its conservation methods related with migratory waterbirds.

In this paper, we analyze the quality of life of children and adolescents with cancer. Separated children and adolescents to treat more than 293 patients myeongreul quit two years to analyze the quality of life. In most previous studies it was to compare the quality of life of the patient to feel the parent to evaluate the quality of life in children and adolescents with cancer. Or It was common practice to evaluate Pediatrics as a group. However, to evaluate a wide range of ages of children and adolescents cancer patients as a basis, there is a problem. Therefore, in the paper according to the degree language understanding and 10 to 12 years old and 13-20 years old classified as two groups. In addition, we use KMMQL-AF questionnaires written in korean. Accurate across the 10 local hospital the experts have described the extraction accompanied by an in-depth interview research surveys for data collection (15.07.2011 - 01.31.2012).

This study evaluated tidal stream energy resources according to tidal flow properties around Uido off the west coast of, Jeollanam-do, South Korea. A feasibility study was first carried out through the collection of bathymetry data and tidal phase information. For this simulation, a depth-averaged 2D ADCIRC (Advanced Circulation) model for real sea situations was applied to a Finite Element Method (FEM) approach for tides given the variation of tidal current speed. Hydrodynamics were simulated with 4 major tidal constituents (M2, S2, K1, and O1) after setting up 4 observation points. From the real depth-averaged model simulation results, it was found that the spring tide Higher High Water (HHW) and tidal current speed values at the 4 observation points were about 2.2 m and 1.33 m/s, respectively. The ADCIRC model results were analyzed with reference to the Korea Hydrographic and Oceanographic Agency's (KHOA) observed data for verification. Furthermore, using topographical characteristics via the Tidal Flux Method (TFM), tidal energy density distribution was calculated, indicating a maximum tidal energy density of about $1.75kW/m^2$ for the 5 assessment areas around Uido. The tidal energy density was evaluated with consideration given to topographical characteristics as well as tidal elevation and tidal current speed to determine an optimum tidal farm candidate.

To prevent and mitigate damage to farms due to heavy snowfall, snow weight information should be provided in addition to snow depth. This study reviews four formulae regarding snow density and weight used in extant studies and applies them in Suwon area to estimate snow weight in Korea. We investigated the observed snow depth of 94 meteorological stations and automatic weather stations (AWS) data over the past 30 years (1988-2017). Based on the spatial distribution of snow depth by area in Korea, much of the fresh snow cover, due to heavy snowfall, occurred in Jeollabuk-do and Gangwon-do. Record snowfalls occurred in Gyeongsangbuk-do and Gangwon-do. However, the most recent heavy snowfall in winter occurred in Gyeonggi-do, Gyeongsangbuk-do, and Jeollanam-do. This implies that even if the snow depth is high, there is no significant damage unless the snow weight is high. The estimation of snow weight in Suwon area yielded different results based on the calculation method of snow density. In general, high snow depth is associated with heavy snow weight. However, maximum snow weight and maximum snow depth do not necessarily occur on the same day. The result of this study can be utilized to estimate the snow weight at other locations in Korea and to carry out snow weight prediction based on a numerical model. Snow weight information is expected to aid in establishing standards for greenhouse design and to reduce the economic losses incurred by farms.

This study examined the relationships among levels of knowledge, attitude and preventive behavior regarding tuberculosis in service workers. The survey period was 1 - 7 October, 2015 with service workers who work in large scale stores in Jeonnam. The collected data were analyzed using an independent t-test, ANOVA, and Pearson's correlation coefficients using the SPSS WIN 12.0 program. The mean score for knowledge about tuberculosis was $14.05{\pm}6.39$, the mean score of attitude toward tuberculosis was $29.87{\pm}4.89$ and the mean score of preventive behavior for tuberculosis was $31.44{\pm}4.86$. Preventive behavior was found to have significant relationships with gender, marital status, smoking, job satisfaction, and subjective health status. A slightly positive correlation was observed between the knowledge of tuberculosis and the attitudes toward tuberculosis. A positive correlation was noted between the attitude toward tuberculosis and preventive behavior for tuberculosis, while there was a negative correlation between the preventive behavior and age. Therefore, is necessary to consider the related factors for the development and implementation of systematic education programs that can encourage and promote preventive behavior for tuberculosis among service workers.

"Boram" is a new $F_1$ hybrid of rapeseed (Brassica napus L.) with early maturing, high yield and high oleic acid. This cultivar was developed from the cross between Mokpo-CGMS (male steile line) and 8634-B-1-3-1-8 (restore line) for the production of edible oil and biodiesel in 2006. Yield trials were conducted from 2007 to 2008 and regional adaptation trials were examined at four locations in 2008. "Boram" has green and parted leaf, yellowish flower, and black seed coat. The ripening period of "Boram" is similar to "Sunmang", but 3 days faster than "Tammiyuchae". The average seed yield of the regional adaptation trials was 424 kg/10a, which was 11 and 48% higher than "Sunmang" and "Tammiyuchae" variety. Total oil content of "Boram" was 44.2%. In fatty acid composition, "Boram" has no erucic acid. However, oleic acid content is 68.5%, which is 3.7 and 5.4% higher than "Tammiyuchae" and "Sunmang". And total glucosinolate content was 2.27mg/g. Therefore this variety is recommended as a leading variety at southwestern areas including Jeonnam, Jeonbuk and Kyeongnam provinces and Jeju island of Korea.

The characteristics of deposits formed by the Daejon-cheon and Soobuk-cheon, dissecting the mountains such as Byungpung Mt. and Samin Mt. in western part of Damyang county, Jeonmam province. Results from field survey and bore hole logging by KIGAM are used in interpreting depositional environment, in this study. By the result of deposits near of the channels Daejon-cheon and Soobuk-cheon, and main channel of Youngsan River, the depth of sediment layers in this area is 4~7m, far thinner than formerly estimated. Weathered material of local rocks forms the base of the sedimentary layers. It can be assumed that the location channel of the Youngsan river has been stable ever since the start of the sedimentary events. Sediment particles of tributaries are angular than those of Youngsan River. Particles are larger and sorting is poor. It is interpreted as mount flash flood deposits. Main sources of sediments at the valley bottom or deposition dominated area are the terrace deposits or slope deposits over the gentle foot-slope or front of surrounding mountains. Some particles show polygonal cracking on the surface originated from the strong chemical weathering, while most of these has high angularity. It means various geomorphic processes operate to produce and transport the particles in this area.Isolated hills within the sedimentary plains are made with weathered materials of local bedrock. In the case of foot-slope of the hills, thin sedimentary layers are found. So it can be concluded that surface features of deposition zone of the Daejon-cheon and Soobuk-cheon is formed by the filling of lower part of the valley and its feature partly controlled by the relief of the weathering front.

The role and ratio of national vessels in the global container shipping market have reduced significantly due to the bankruptcy of Hanjin Shipping in early 2017. All import-export companies, as well as container ports in Korea, are facing a crisis. The Trump's tariff and trade battles have had a negative impact on the increase in the North American cargo. However, Chinese and Japanese container shipping companies, which merged with domestic container shipping companies, and mega carriers such as Maersk and CMA CGM have benefited from the decline in shipping supplies due to the collapse of Hanjin Shipping, the world's 10th largest container carrier in Korea. The import/export freight trade in Korea is witnessing the increasing stronghold of foreign carriers. This scenario is expected to weaken Korea's negotiation powers with overseas shipping companies in domestic ports, such as Busan and Kwangyang, thereby making it more challenging to attract shipping carriers. This study compares the global container-shipping network in 2007 and 2017 by combining the network topology of the social network analysis and the economics of the liner shipping connectivity index (LSCI) and the container port connectivity index (CPCI) analysis. The findings of this study are that the role of the ports across the world can be identified, and CPCI has a high correlation with the centrality index and freight volume data. These findings can contribute toward the utilization of the meaning of the necessary centrality index without an additional centrality analysis. This study can be applied not only to the call strategy of container carriers but also to the alliance and development strategy of Korean ports.

This study analyzed the status of tuberculosis patients in Korea by collecting data from the Statistics Korea and the KDCA's GLOBAL Tuberculosis Report from 2010 to 2018 to find ways to manage tuberculosis patients in Korea and provide basic data on tuberculosis policies. The results are as follows. First, the results of tuberculosis patients in Korea decreased by about 21.3% to 33,796 (65.9%) in 2018 and 26,433 (51.5%) in 2018. Second, the status of tuberculosis patient treatment in Korea was found to be 655 in 2018, an increase of about 160% compared to 2014. Third, the incidence of tuberculosis among adolescents was 1.8% in 2018 for those aged 10 to 14 and 15.0% for those aged 15 to 19, the highest rate of tuberculosis among high school students, Fourth, looking at the incidence of tuberculosis patients by age, subjects in their 60s or older showed a prevalence of tuberculosis by 60% or more, especially elderly tuberculosis patients over 80 years of age. Fifth, the status of the incidence of tuberculosis patients by gender was found to be 1.4 times higher in men than in women in 2018 compared to 2010. Sixth, 1,419 people (75.6%) in Jeollanam-do had the highest prevalence of tuberculosis nationwide, and 99 people (33.4%) in Sejong had the lowest prevalence. Seventh, the number of foreign patients in Korea continued to increase to 1,510 in 2012, increasing to 2,569 in 2016. The results this study indicate the need for rapid and accurate early tuberculosis screening policies and management for tuberculosis relapse patients, high school student, age groups over 60, a group of men such as the military, the elderly over 80, and foreigners.
