  • The purpose of this study was to analyze high schools' general and special subject required to successfully complete same stream curriculum which is identical to their major from agricultural high school, and to offer basic data on strategies of organizing agricultural high schools' curriculum for improving universities' major basic competencies. Using purposeful sampling technique, the professors of 116 universities professors in 8 agricultural university were analyzed through the survey research. The result was as follows. first, it appeared that for successful completion of major subjects of the same stream university, the basic science subject such as biology and chemistry has high relation with major basic ability, however math and physics are related highly in agricultural machine and agricultural civil engineering department, economics and math are in agricultural produce distribution department. Second, the basic ability such as linguistic competence and foreign language ability are essential to complete major subject. Third, if we look into relation of agriculture and life science industry stream specialized subject with major basic competencies, we can find considerable similarity between major field of university and subject name of specialized high school. Fourth, the main opinion is that basic concept and principle, laws of nature are should be main contents which is able to be practical, however experiment and practice is in food processing department, and academic theory is in biotechnology department.

  • This study was conducted to expand the distribution of new technology efficiently by analyzing the structure relationship based on the innovation resistance model and partial least square structural equation model (PLS-SEM). This study selected innovative propensity, relative advantage, compatibility, complexity, trialability, risk, and extension service consisting of educational, technical, and funding services as factors affecting innovation resistance. This study constructed a questionnaire that measured 11 factors including acceptance intention of new technology using 33 indicators. Data was from April to October, 2017, targeting 180 farmers who did not join in projects to spread new technologies of the Rural Development Administration. Results showed the factors positively and significantly affecting innovation resistance include complexity and risk. Innovative propensity did not have any effect on innovation resistance. However, it positively affected acceptance intention of new technology. The service of the extension organizations had a negative effect on innovation resistance, but did not affect acceptance intention of new technology. This study suggests that extension services should promote activities such as education, consulting, publicity and pilot projects related with new technologies in order to minimize the antipathy toward new agricultural technologies.

  • The purpose of this study was to investigate the relationship between self-esteem and differentiation of self, and to identify the degree of self-esteem and differentiation of self. Data were collected from 151 elementary school students using community child center. Factor analysis, reliability analysis, correlation analysis, regression analysis, and cluster analysis were performed. The results of the study are as follows: First, as a result of factor analysis, differentiation of self was classified into differentiation of internal mind, other's and self oriented. Self-esteem was classified into isolation, achievement, relation, and daunted. Second, regression analysis indicated that there was obvious relationship between self-esteem and the differentiation of self. Third, cluster analysis showed that 37.6% of children belonged to cluster 2 with achievement and relation patterns and self-oriented differentiation. Forty-three percent were belonged to cluster 1 with isolated and daunted self-esteem as well as internal mind and other's oriented differentiation. In cluster 3, 19.4% were belonged and their levels of self-esteem and the differentiation of self were very low. Findings indicate that for those children belonged to cluster 1 and 3, programs to raise the self-esteem of children and parental education are needed.

  • Focusing on the potential impact of information and communication technology (ICT) on older adults' quality of life, this study empirically examined the influence of smartphone use in old age on life satisfaction, depression, social activity and social support of Korean older adults. In order to examine the effects of smartphone use, this study analyzed data from 630 questionnaire surveys from older adults aged 65 and over living in Seoul. The effects of smartphone use were tested using hierarchical multiple regression analysis, controlling for socio-demographic variables such as age, sex, spouse, education and income. Results showed that the effects of smartphone use on life satisfaction, depression and social activity of older adults were statistically significant. However, the effects of smartphone use on social support of older adults was not statistically significant. This study suggests that ICT such as smartphones in old age plays generally positive roles in enhancing psychological, mental and social aspects of quality of life. This implies that further practical efforts to expand the distribution and use of ICT in old age are required to improve quality of life and successful aging of older adults.

  • From January 2 to December 30, 2017, out of 691 children diagnosed with dermatophytoses infection, 179 children had infections caused by Trichophyton among the total 13,093 patients who visited the Dermatology department. According to a survey, the patients included 317 adolescents, 203 elementary school age children, and 171 infants. In seasonal variation, the diagnosis was higher in summer (195 cases, 28%) and winter (191, 28%) and comparatively lower in spring (165, 24%) and autumn (140, 20%). The infection among the patients was caused by, from maximum to minimum, T. pedis (351, 51%), T. corporis (91, 13%), and T. unguinum (77, 11%). In all age groups, the highest number of patients were infected with T. pedis. After T. pedis, in descending order, the infection was caused by T. corporis, T. unguinum, T. manus and Tinea capitis in the infants and elementary school age children and by T. corporis, T. unguinum and T. cruris in adolescents. Among infections caused by Trichophyton, T. rubrum was the highest isolated causative agent. This data analysis confirmed the distribution of dermatophytoses and the different species according to paediatric age and will aid the study of paediatric dermatomycosis through continuous research.

  • Radiation dose enhancement is a method of increasing the cross section of interaction, thus increasing the deposited dose. This can contribute to linear energy transfer, LET and relative biological effectiveness, RBE. Previous studies on dose enhancement have been mainly focused on X, ${\gamma}-rays$, but in this study, the dose enhancement was analyzed for proton using Monte Carlo simulation using MCNP6. Based on the mathematical modeling method, energy spectrum and relative intensity of spread out Bragg-peak were calculated, and evaluated dose enhancement factor and dose distribution of dose enhancement material, such as aurum and gadolinium. Dose enhancement factor of 1.085-1.120 folds in aurum, 1.047-1.091 folds in gadolinium was shown. In addition, it showed a decrease of 95% modulation range and practical range. This may lead to an uncertain dose in the tumor tissue as well as dose enhancement. Therefore, it is necessary to make appropriate corrections for spread out Bragg-peak and practical range from mass stopping power. It is expected that Monte Carlo simulation for dose enhancement will be used as basic data for in-vivo and in-vitro experiments.

  • The companion animal related businesses are rapidly growing as the pet population increases in Korea. In this study, we analyzed the market trends of companion animal food and products to offer basic information that can be used in related policies and industries. The data were collected using Nielsen Korea's wholesale/retail distribution channels. As a result, in the case of companion dog food, PB products of domestic companies showed the highest market share with 24.6%, and the ratio of domestic companies(54.8%) was higher than that of import companies(45.2%). Domestic PB products also had the highest market share(16.5%) in companion cat food, however, the ratio of import companies(71.6%) was higher than that of domestic companies(28.4%). In the case of the market share of the companion animal products(toys, oral and bath supplies), Nosework mats from domestic companies were top ranked in the toy category(28.0%). Oral products(62.5%) and bath products(59.5%) from domestic companies were also having a higher market share than import companies. Our research may help domestic companion animal product companies to steadily increase market share and the amount of their export.

  • In rural areas, composting is a source of non-point pollutants. However, as the quantitative distribution and loading have not been estimated, it is difficult to determine the effect of composting on stream water quality. In this study, composting datum acquired by unmanned aerial vehicle(UAV) was verified by using terrestrial LiDAR, and the management status and load change of the composting was investigated by UAV with manual control flight, thereby obtaining the basic data to determine the effect on the water system. As a result of the comparative accuracy assessment based on terrestrial LiDAR, the difference in the digital surface model(DSM) was within 0.21m and the accuracy of the volume was 93.24%. We expect that the accuracy is sufficient to calculate and utilize the composting load acquired by UAV. Thus, the management status of composting can be investigated by UAV. As the total load change of composting were determined to be $1,172.16m^3$, $1,461.66m^3$, and $1,350.53m^3$, respectively, the load change of composting could be confirmed. We expect that the results of this study can contribute to efficient management of non-point source pollution by UAV.

  • In the Jirisan area of the Yeongnam Massif, Korea, several ductile shear zones are developed within Precambrian gneiss complex (Jirisan metamorphic rock complex). The ductile shear zones have a general NS- and NNE-striking foliation with westward dipping directions. The foliation developed in the shear zones cut the foliation in gneiss complex. The stretching lineations are well developed in the foliated plane of the shear zone, showing ENE-trend with gentle plunging angle to the ESE direction. Within shear zone, several millimetric to centimetric size of porphyroclasts are deformed strongly as a sigmoid form by ductile shearing. The sigmoid patterns of porphyroclasts in the shear zones indicate the dextral shearing. The spatial distribution of ductile shear zone is characterized by the dominant NS- and NNE-striking dextral sense in the central and eastern regions respectively. In the western part, it develops in NE-striking dextral sense which is the general direction of the Honam shear zone. The U-Pb concordant ages obtained from the two samples, the strongly sheared leucocratic gneiss, are $1,868{\pm}3.8Ma$ and $1,867{\pm}4.0Ma$, respectively, which are consistent with the U-Pb ages reported around the study area. We supposed that the ductile shearing in the study area is occurred about 230~220 Ma during late stage of the continental collision around Korea and is preceded by granitic intrusion related to subduction during 260~230 Ma, which are supported by compiling the age data from sheared gneiss, deformed mafic dyke intruded gneiss complex, and non-deformed igneous rocks.

  • This study compared the characteristics of the optimization technique and the water supply and demand forecast using K-WEAP (Korea-Water Evaluation and Planning System) model and MODSIM (Modified SIMYLD) model considering wtaer supply priority. Currently, The national water resources plan applied same priority for municipal, industrial and agricultural demand. the K-WEAP model performs the ratio allocation to satisfy the maximum satisfaction rate, whereas the MODSIM model should be applied to the water supply priority of demands. As a result of applying the priority, water shortage decreased by an average of $1,035,000m^3$ than same prioritized results. It is due to the increase of the return flow rate as the distribution of Municipal and industrial water increases. Comparing the analysis results of K-WEAP and MODSIM applying the priorities, the relative error was within 5.3% and the coefficient of determination ($R^2$) was 0.9999. In addition, if both models provide reasonable water balance analysis results, K-WEAP is superior to GUI convenience for model construction and data processing. However, MODSIM is more effective in simulation time efficiency. It is expected that it will be able to carry out analysis according to various scenarios using the model.
