This study was performed in part with the task to find measures to improve the defining characteristics of feelings, value, interest, self-efficacy, and others aspects in regards to learning math among elementary and middle school students. For this study, it was essential to understand the appropriate questions that are needed to be asked during a consultation at a math clinic, for students that are having a hard time learning math. As a method for performing this study, the content of scheduled counseling over 2 years from a math clinic were collected and the questions that were given and taken were analyzed in order to figure out the types of questions needed in order to effectively examine students that are facing difficulty with learning math. The analysis was performed using Grounded theory analysis by Strauss & Corbin(1998) and went through the process of open coding, axial coding, and selective coding. For the paradigm in the categorical analysis stage, 'attitude towards learning math' was set as the casual condition, 'feelings towards learning math' was set as the contextual condition, 'confidence in one's ability to learn math' was set as the phenomenon, 'individual tendencies when learning math' was set as the intervening condition, 'self-management of learning math' was set as the action/interaction strategy, and 'method of learning' was set as the consequence. Through this, the questions that appeared during counseling were linked into categories and subcategories. Through this process, 81 concepts were deducted, which were grouped into 31 categories. I believe that this data can be used as grounded theory for standardization of consultation in clinics.

Objectives : The aim of this study was to draw attention toward so called 'behavioral variant frontotemporal dementia(bvFTD) phenocopy syndrome', which is difficult to discriminate with the primary psychiatric disorders, showing poor response to conventional therapeutic drugs, leading to higher risk to misdiagnoses and legal problems. Furthermore, the author insisted that our interest and study on them must be continued. Methods : English articles published during 2000 thru 2016 had been searched by internet with the combination of words such as 'frontotemporal', 'phenocopy' and 'behavioral', and reviewed. Besides, two clinical vignettes were described. Results : Precise diagnosis is important because patients' behavioral symptoms can influence on their families and community. However, disease-modifying treatment for bvFTD are not developed until now, and recent therapeutic drugs are only good for specific symptoms, while deterioration progresses in spite of proper psychiatric management. The possible bvFTD patients are not progressed into probable bvFTD clinically, showing no decline of cogntive and social function, no decrease of activity function, longer survival time, and normal neuroimaging for several years. Conclusions : Rather than expected, there are much more patients having clinical symptoms, course and diagnostic findings including neuroimaging, which are atypical to classical frontotemporal dementia and primary psychiatric disorders. If our knowledge and discriminating ability is improved, discovery rate of that cases will be increased. However, the identity of these atypical features are not clarified until now, it must be further actively investigated.

As the necessity of humanistic education has recently been socially emphasized, aptitude and character test has been conducted in the stage of training instructors to focus on making them equipped with proper ability of humanistic education. Especially, considering characteristics of students in specialized high schools with stronger negative concept of ego along with higher proportion of students looking for job in early ages compared to regular high schools, instructors in specialized high schools need to pay more attention on humanistic education of students compared to those in regular high schools. Therefore, this study has developed social emotion learning (SEL) of preliminary teachers in specialized high schools and analyzed the influence of developed programs on characters in teaching positions of preliminary instructors in specialized high schools. In this study, ADDIE model has been used developing SEL programs, and developed programs were comprised of total six sessions. Social emotion learning has been performed on 27 preliminary teachers in experiment group, and regular academic education courses were given on 30 preliminary teachers in control group. At this time, as for class contents, 'self-recognition' has been dealt with in the first and second sessions followed by 'self-management' in the second and third sessions, 'adjustment in relationship' in the fourth session, 'responsible decision making' in the fifth session, and 'personal relationship' in the sixth session. Classes have been conducted for 90 minutes in average. Since intentional sampling method has been used in this study, difference of pre-scores between groups might influence on the difference on post-scores. Therefore, ANCOVA that adjusted the pre-scores to be consistent has been utilized. As a result, there was a significant difference on the post-scores in characters in teaching positions between experiment group and control group.

Volatile organic compounds (VOCs) are widely used in both industrial and domestic activities. VOCs are one of the most unpleasant, frequently complaint-rousing factors of pollution around the world. It is now necessary to research and develop an alternative technology that could overcome the problems of the existing odor-control and VOC-eliminating techniques. In this study, essential oil and photocatalytic process was applied in the removal of benzene and toluene, typical VOCs in petrochemistry plant. therefore, this study conducted experiments on the selection of appropriate essential oil, photodegradation, hydroxyl radical generation capacity. The removal efficiency and reaction rate were performed to selecte the type and concentration of essential oil. As a result, removal efficiency of Hinoki Cypress oil was approximately 70% and reaction rate of Hinoki Cypress was high. The results of photolysis experiment, photocatalytic oxidation process showed that the decomposition efficiency of VOCs increased considerably with increasing UV lamp power. In addition, the conversion of VOCs was increased up to $0.1gL^{-1}$ photocatalysts. The hydroxyl radicals measure was performed to determine the ability to generate hydroxyl radicals. The analytical result showed that high $TiO_2$ concentration and lamp power was produced many hydroxyl radical. Experiments of the removal efficiency and reaction rate were performed using essential oil and photooxidation. As a result, the removal efficiency showed that the removal efficiency was increased high temperature and reaction time. The activation energy was calculated from the reaction rate equation at various temperature condition. Activation energy was approximately $18kJmol^{-1}$.

This study attempted to identify the entrance exam stress levels in high school students and analyze the relationship this entrance exam stress and perceived oral health status. Self-administered survey was conducted in total 304 students attending in academic high schools in Bucheon. For analysis, SPSS was used to perform t-test and one-way ANOVA. As a result of the study, the entrance exam stress level of academic high school students was 2.71. The level of sub-factors were that tension for exam/poor result was highest by 3.08 and the next were future uncertainty (2.81), parents pressure (2.56), and insufficient free time (2.52). The group with high entrance exam stress showed significantly high perceived degrees of temporomandibular disorder, oral mucosal disease and xerostama. Among sub-factors of stress, the group with high tension for exam/poor result stress had significantly high perceived degrees of dental caries, teporomandibular disorder, oral mucosal disease and xerostama. Because perception on oral health issues increased with high entrance exam stress in high school students, it is necessary to seek some ways to decrease oral health problems even though entrance exam stress is intensified. To do so, it is inferred that it will be very important to promote oral health education to develop ability of high school students to practice correct oral management method.

Soils are the basis for plant rooting and ecosystem creation, the site of life for humankind, and require much time for their creation, so there will be no disagreement about the importance and necessity of soil conservation and management. Soil resilience is the ability of soils to maintain their original structure and function (resistance and recovery) from various kinds of disturbances, and is an indispensable field of study that prepares for a future with high uncertainty and unpredictability. Therefore, this study summarizes the concept and necessity of soil resilience, which is not yet widely known in Korea, and the contents of previous studies were reviewed. This study was carried out with the aim of contributing to lowering the threshold for entry into resilience research for domestic and foreign researchers who are new to soil resilience. In the first part of this study, we introduced resilience and soil resilience, and in the second part, we summarized the main causes of stress or disturbance that have been studied by many soil resilience researches. This makes it easy to find the references authors need. It is virtually impossible to find the same soil environment because there is no same area on the earth with all the same rock, climate, human activity, and culture, suggesting that each soil has its own uniqueness. Therefore, the researcher who wants to utilize the results of this study should take into consideration the specificity of the soil and the region to which the soil resilience is introduced, and modify it if necessary. In addition, efforts should be made to strengthen the network of soil resilience researchers to create a basis for sharing and actively utilizing the research results.

It is said that stress is the threat of peace and excess of resources which man has from special relationship between individual and environment. This study is for suggesting the method of intervention of the clinical social work service concerning stress for the adolescents who can conceive looking into the relationship between adolescent pregnancy and stress through the sundry records for them. When the change of making into parents from pregnancy overlapped with stress in the cycle of life as an adolescent period itself, the accumulated stress grows much bigger. The repeated change causes an obscurity of individual role and worsens stress and brings confusion on a priority ranking of developmental task. The pregnancy of adolescence has a demoralizing influence upon the adolescents themselves who are going to be adults, their children, and society. These negative effects won't be end in a short period so the effort of intervention in necessary to improve the coping skills and adaptability of pregnant adolescents. In case of pregnant adolescents, the approach of personal counsel is not just enough and effective prevention program can be better alternative and purpose at the same time. This intervention protects adolescents from the distress which can be easily disclosed after delivery and contribute to promote a good mental health of adolescents who will grow to be adults later. After all it implies the necessity of stress management program which can improve the coping ability against stress and develop positive recognition for the pregnant adolescents. Therefore much profounder study for practical intervention program, implementation, and evaluation is necessary with the conclusion which has the results of this literature study.

Water quality is affected by the pollutants flowing into rivers since the interaction between water bodies and sediments in various environmental conditions. Especially, accumulation of sediments increases in the stagnant water areas due to a relative long hydrological retention time in the water bodies. Therefore, it is an important factor of water quality to understand characterization of the material behavior in water bodies and sediments. In this study, the objective of the conditional experiments was small and medium sized streams located in Gyeonggi-do. To estimate how the changes of fluoride behavior, depending on the pH, ion type, concentration, and clay contents. The pH results showed a trend that adsorption amount of fluorine decreased and the dissolution of fluorine increased following by pH increasing. The concentration and type of ions results showed that $Cl^-$ and $SO{_4}^{2-}$ ions had no significant effect on the adsorption ability of fluorine, the amount of dissolution was increased because $OH^-$ ion had active competition with fluorine in the reaction. The ingredient of sediment results showed that the amounts of fluoride adsorption and dissolution were reduced in samples, which contain relatively large amounts of Silt and Clay components. This means that the environmental conditions of water bodies greatly affect the adsorption and dissolution of fluoride in the sediments, so that proper management of fluoride in the sediments must precede an understanding of the environmental conditions of the water bodies.

Nowaday, beyond the time of wellbeing and LOHAS, many people have great interest in self therapy, so it is called healing era. As the folk medicine fields are actively industrialized and the interest in health improvement, not disease cure, is increased, many researches about the alternative medicine and therapy in various fields are being performed. In the times of the interest in health improvement and spontaneous, natural healing ability of human body is getting increase, it is very meaningful to search the factors which consist of recognition to folk medicine. So in this study, we developed the questionaries on the basis of previous studies, researched the factors affecting the recognition to folk medicine using factor analysis, and tested statistically the difference of recognition character according to demo-statistical traits. As the result, the twenty-four measurable variables related to folk medicine are sorted to four factors, ie, health improvement factor, safety factor, psycholocial factor, and substitutional factor. And overall, the middle and senior ages, the forties to sixties, and higher-educated peoples have more experiences in folk medicine than the younger ages, below thirties and lower-educated peoples. The distiction of sex makes little differences.
