As many precedent studies have shown, most children grow receiving influence from their parents. The purpose of this study was to serve as a basis for better preventive approach by finding out the relationship between the attention-deficit hyperactivity disorder(ADHD) of elementary school children and maternal behavior characteristics. Moreover, the purpose of this study was to present basic materials for developing program of children and create good relationship between child and parents for better education. For the purposes, two hypotheses were posed. Hypothesis 1： There would be a significant disparity in maternal behavior between the ADHD group and the non-ADHD group. Hypothesis 2： The environment could have an influence on maternal behavior characteristics. The subjects in this study were 71 mothers who had children with ADHD and 69 mothers who had non-ADHD, who selected from mothers of third to sixth graders in elementary school in Kyonggi, Suwon. The instruments used for the diagnosis of ADHD was DSA-IV. The data were analyzed with ANOVA(Analysis of Variance) by SPSSWIN Program. The findings of this study were as fellows： First, Hypothesis 1 was accepted. The mothers who had ADHD children had rejective behavior characteristics in while the mothers group who had non-ADHD children had controling behavior characteristics but there was no significant difference in affectionate attitude and autonomic attitude. Second, hypothesis 2 was accepted generally. The psychological and physical environment had correlation with maternal behavior characteristics. Especially, there was a significant correlational relationship between the maternal satisfaction for their life and rejection of maternal behavior. The following conclusion could be made from the above mentioned findings. First, The maternal behavior characteristics resulted in severe ADHD for children which justified the need of proper education for mothers to care children wellbeing. Second, The environment of psychology had an influence on maternal behavior. This showed that it is essential to develope educational program and counselling system for mothers

Theileria (T.) buffeli (formerly T. sergenti/T. orientalis) is the major hemo-protozoan distributed in the Far East Asian countries such as Korea, China and Japan. It is responsible for the clinical symptoms of anorexia, ateliosis, anemia, fever and icterus. It also causes abortion and sudden death under severe cases, resulting in economic losses for many livestock farms. The objective of this study was to analyze the genetic diversity of the major surface protein (Msp) gene in T. buffeli in Holstein in Korea, and we characterized the association of the diversification of the Msp gene and its relationship with the pathogenicity of Theileria. For this, complete blood counts and Theileria PCR sequence analysis were performed from 57 Holstein in Jeju Island. A total of 26 PCR positive Holstein (16 anemic and 10 non-anemic) were then randomly selected based on 18s rRNA sequence typing of the Theileria Msp gene. The DNA sequence of the T. buffeli Msp gene in Holstein showed 99.0%, 99.2%, 99.9%, 99.5%, 98.7%, 98.4% and 98.4% homology with T. sergenti, Theileria spp., T. sergenti, Theileria spp., Theileria spp., Theileria spp. and Theileria spp., respectively. The result showed a genetic variation of 57.7% (type I), 3.8% (type II), 15.4% (type III), 7.7% (type IV), 13.5% (type V) and 1.9% (type VI). Type I is the most frequent type in both anemic and non-anemic Holstein while type II was found in only non-anemic Holstein. This results of our study help confirm the diversity of Msp gene types and demonstrate that the gene type distribution of Msp genes varies among Theileria-infected Holstein in Jeju Island.

The purpose of study was to examine and compare the self-esteem, interpersonal relationship, happiness, and college adjustment between Type D and non-Type D personality among nursing students. Subjects included a total 181 nursing students (Type D personality: n=53, non-Type D personality: n=128). Data were collected through personal interviews using a questionnaire. The collected date were analyzed using a ${\chi}^2$-test, Fisher's exact test, and independent t-test. There were significant differences on self-esteem, interpersonal relationship, happiness, and college adjustment between Type D and non-Type D personality among nursing students. Self-esteem showed significant differences in degree of adaption, interpersonal relationship in religion, happiness in economic status, college adjustment in religion and degree of adaption (Type D personality subjects). Type D personality lowered self-esteem, interpersonal relationship, happiness, and college adjustment in nursing students. Strategies for Type D personality in nursing students are needed to increase self-esteem, interpersonal relationship, happiness, and college adjustment.

Objectives We aimed to investigate the effectiveness of the Korean medical critical pathway (CP) in treating childhood anorexia. Methods In total, 21 patients who met the criteria and agreed to provide information were assigned to the CP group, while 24 patients who met the criteria, agreed to provide information, but disagreed with CP application were assigned to the non-CP group. Demographic, clinical, and economic indices were compared between the two groups. Clinical indices before and after treatment were also compared between the two groups. Results In the CP group, height, weight, body mass index (BMI), BMI percentile, and food approach (FAP) increased significantly after treatment, and numeric rating scale (NRS) and food avoidance (FAV) scores decreased significantly. In the non-CP group, height, weight, weight percentile, BMI, BMI percentile, and FAP increased significantly, whereas NRS and FAV decreased significantly after treatment. Compared to the non-CP group, CP application increased FAP and decreased FAV, medical expenses per consultation, and the total treatment period. Conclusions The application of the Korean medical critical pathway for childhood anorexia is an effective cure system that decreases overall medical expenses with good-quality treatment by means of the standardization of medical practices.

It was found that there was no problem in recycling by-products (waste rock and tailings) from Yangyang iron mine themselves through matter conversion because they are not hazardous according to results of KSLT method. In case of using tailings as sub-materials of cement, it recommended the use of less than 3% tailings dosage not to exceed 0.6% of total alkali ($R_2O$) content based on standard quality of portland cement (KS L 5201). Non sintered eco-brick corresponding to class 1 quality of recycled clay brick (KS I 3013) can replace 15% of cement with tailings and 100% of general fine aggregate with waste rock from iron mine. As mentioned above, recycling the by-products (waste rock and tailings) as sub-materials of cement and non sintered eco-brick could gain both environmental and economic benefits, that is, reduction of scale and maintenance cost of tailing ponds, decrease of energy use and $CO_2$ emission.

To assess the total cost with all stages of facilities, the feasibility of Life Cycle Cost (LCC) analysis was examined in this study to estimate the livestock manure treatment system and optimal decision making process. For the economic evaluation, the plant/equipment investment and annual operation cost of four Public Livestock Recycling Facilities, whose treatment capacity is 100 ton piggery manure per day, was compared. The initial cost was in the range of 2,699 million won to 3,202 million won, where T and E methods were highest and lowest, respectively. The annual operation cost was in the level of 378 million to 498 million won, which decreased in the following order : T method > J method > E method > B method. For the LCC analysis, 4.7% of interest rate, 3.13% of inflation rate, and 1.52% of net discount rate was considered by the data received from Bank of Korea and Statics Korea in the period of 2000 to 2009. Also, for the calculation of present value factor, the durable years of civil engineering & construction, machinery and electric instrument was 30 years, 10 years and 15 years, respectively. Based on these consideration, operation cost was in the range of 17,570 won/ton to 20,661 won/ton, and E method (17,570 won/ton) was economical and B method (20,661 won/ton) was non-economical. Though initial cost of T method was higher than that of B method, LCC analysis of T method was lower than that of T method due to the lower operation cost. Therefore, LCC analysis, which considers both initial cost and operation cost, is more reasonable evaluation method than either initial cost or annual operation cost. For the change of LCC analysis according to the uncertainty, the sensitivity analysis was carried out using fluctuation magnitude of discount rate in the period of 2000 to 2009. As a result, LCC analysis evaluated by discount rate was stable for the uncertain factors since the cost leadership did not change even though the sensitivity analysis varied. In summary, the economic evaluation using LCC analysis could be an efficient reference to choose the suitable livestock manure treatment plants. Furthermore, standardization of statement calculation for the actual cost analysis should be conducted and more detailed study is necessary to validate this summary. Therefore, the application of comprehensive technology evaluation, which considers LCC analysis, should contribute in obtaining objectivity and enhancing reliability for the 'Evaluation of Livestock Manure Treatment System and its Technology'.

Recently, in the domestic amount of materials,curtailment and economic efficiency security by purpose, tapered beam application is achieved, but the architectural design technology of today based on the material non-linear method does not consider solutions to problems such as brittle fracture. So, geometric non-linear evaluation thatincludes initial deformation, width-thickness ratio, web stiffener and unbraced length is required. Therefore, in this study, we used ANSYS, a proven finite elementanalysis program,and material and geometric non-linear analysis to study existing and completed tapered H-section as deep beam's analysis model. Main parameters include the width-thickness ratio of web, stiffener, and flange brace, with the experimental result obtained by main variable buckling and limit strength evaluation. We made certain that a large width-thickness ratio of the web decreases the buckling strength and short unbraced web significantly improves ductility.

After the announcement of Moon Jae-in Government's plan (Moon's Care) for Benefit Expansion in National Health Insurance in August 2017, it is necessary to monitor the effects of the policy, especially household out-of-pocket payments (OOP). This paper aims to observe the current status and trend of OOP in Korea. Current health expenditure (CHE) was 144.4 trillion won in 2018, which accounts for 8.1% of gross domestic product (GDP) increased 9.7% from the previous year. Although GDP's share of CHE has been close to the average of the Organization for Economic Cooperation and Development (OECD) countries, the public fund's share was 59.8% of the total in 2018, which was lower than the OECD average of 73.5%. OOP's share was 32.9% in 2018, which decreased from 37.4% in 2008. The share of OOP of non-covered services was 20.0% in 2018, which decreased from 22.9% in 2008. The share of cost-sharing with third-party payers was 12.9% in 2018, which decreased from 14.5% in 2008. The OOP of non-covered services was significantly decreased in hospital and inpatient curative care, but the OOP of non-covered services was significantly increased in the medical clinic. The effect of Moon's Care was not showed in OOP through the results of 2017 and 2018, but further monitoring is needed because the Moon's Care is progressing and the observational period is short.

Background: The purpose of this study is to provide the data for discussions related to oral health promotion policies for single-person households by analyzing the status of unmet dental needs and related factors in single-person households in Korea, based on the Anderson model. Methods: The data, obtained from 544 single-person households of those over 20 years old who were targeted for the 6th Korea National Health and Nutrition Examination Survey, were analyzed through a complex sample frequency analysis, complex sample cross analysis (Rao-Scott chi-square test), and complex sample binary logistic regression analysis on a complex sampling design. Results: The most frequently given reason for an unmet dental need among single-person households was economic (52.4%). Factors related to the unmet dental needs of single-person households are smoking, which is a predisposing factor; personal income levels, which are an enabling factor; chewing discomfort; and limited daily activities, which are need factors. Smokers, the high-income group, the chewing-discomfort group, and the limited activity group showed high unmet dental care experience. Smokers had a 2.75 times higher rate of unmet dental care than non-smokers, and the high-income group had a 5.29 times higher rate of unmet dental needs than the median group. The rate of unmet dental needs for the chewing discomfort group was 3.27 times higher than the non-chewing discomfort group, and the limited activity group had a 7.87 times higher rate of unmet dental needs than the non-limited activity group. Conclusion: It is necessary to map out policies designed to help maintain and promote met dental needs considered to be internally heterogeneous to single-person householders, based on the Anderson model.
