Concrete, which is the most widely used building material in modern times, has been improved not only in strength but also in structural performance such as increase in toughness and ductility, weight reduction, and improvement in quality of human life. Due to the surge in demand for the building, there is a tendency to be used variously from architectural panel and architecture to interior accessories. In Korea, a light-transmitting concrete, LEFC(Light Emotion Friendly Concrete), that insert plastic rods to stimulate emotional sensation through the combination of light and concrete has developed. In previous research, it was confirmed that the use of a synthetic foam agent rather than an animal foam agent did not cause a fogging phenomenon. In this study, lightweight by applying foaming agent to LEFC and two types of fiber (Nylon Fiber, Polyvinyl Alcohol) were compared to achieve to investigate the fiber to be applied in future. An equation that can predict the loss and adhesion reduction of the concrete section according to the diameter of the rod (5mm, 10mm) and the interval (10mm, 15mm, 20mm) was proposed.

There are many different job skill evaluation scales, but the development of the job skill scale for the workers in the local child care centers has much to be improved. The purpose of this study is to develop and validate the job skill scales for the workers of local child care centers. It is also the purpose of this study to specify the scope of work for such workers and define the job skills to develop a tool to evaluate the job skills of them, eventually. As for the study method, the researcher conducted literature review and Delphi survey to extract the job skill factors. Then, after going through a discussion with an expert, the researcher developed the preliminary questions to verify the validity of the contents and the certification validity. For this, a survey was conducted with the workers in local child care centers across the country, and a total of 221 questionnaires have been used for analysis. With this, a total of five job skill factors for such workers were identified, based on which 20 questions were developed to constitute the scale. The sub-factors identified were student supervision, program planning, child education, administrative works, and link-up with the local community. The confidence level of the scale developed in this study was Cronbach ${\alpha}=.940$(N=221). With the scale of the job skills of the workers in local child care centers, it would be possible to develop various job skill programs. And, this would be able to be used for evaluating the job skill levels of not only the workers in the local child care centers but also other child-care service providers.

This study aimed at developing an accelerated collection method that reduces measurement and collection time by improving and complementing the desiccator method, which is mainly used for quality control in wood-based panels and furniture production sites. First, this study measured the formaldehyde emissions from the wood-based panels by grade using the desiccator method. Further, this study compared the desiccator method with the developed process and analyzed the correlation in optimal temperature, time, and exposed area. The results showed that the developed process resulted in relatively similar outcomes in comparison to the desiccator method when the temperature was $100^{\circ}C$, the time was 1 h, and two specimens were used, at which the correlation was high. To verify the developed process, this study commissioned Korea Conformity Laboratories with the standardized temperature, time, and the number of specimens to compare them with the specimen that was not used in the actual test. As a result, the correlation to the desiccator method was shown to be very high. However, the formaldehyde emission measured by the accelerated collection process was mostly higher than that measured by the desiccator method. The formaldehyde emission grades from several specimens were one level higher. However, from the perspectives of quality control, it was determined that the accelerated collection method developed in this study could be sufficiently used.

In order to identify the characteristics of sea surface temperature (SST) differences between microwave SST from GCOM-W1/AMSR2 and in-situ measurements in the western coast of Korea, a total of 6,457 collocated matchup data were produced using the in-situ temperature measurements from marine buoy stations (Deokjeokdo, Chilbaldo, and Oeyeondo) from July 2012 to December 2017. The accuracy of satellite microwave SSTs was presented by comparing the ocean buoy data of Deokjeokdo, Chilbaldo, and Oeyeondo stations with the AMSR2 SST data more than five years. The SST differences between the microwave SST and the in-situ temperature measurements showed some dependence on environmental factors, such as wind speed and water temperature. The AMSR2 SSTs were tended to be higher than the in-situ temperature measurements during the daytime when the wind speed was low ($<6ms^{-1}$). On the other hand, they showed positive deviation increasingly as the wind speed increased for nighttime. In addition, increasing tendency of SST differences was related to decreasing sensitivity of microwave sensors at low temperatures and data contamination by land. A monthly analysis of the SST difference showed that unlike the previous trend, which was known to be the largest in winter when strong winds were blowing, the SST difference was largest in summer in Deokjeokdo and Chilbaldo buoy stations. This seemed to be induced by differential tidal mixing at the collocated matchup points. This study presented problems and limitations of the use of microwave SSTs with high contribution to the SST composites in the western coastal region off the Korean peninsula.

The purpose of this study is to develop a STEAM program for teaching climate change through CLAMP (Climate-Leaf Analysis Multivariate Program) paleoclimate inquiry in connection with high school 'Integrated Science' subject. In order to do so, we analyzed the 2015 revised national curriculum and science textbook in terms of the PDIE instructional design model, and developed the teaching-learning materials for 10 class hours through expert panel discussion and pilot test. According to the STEAM class procedure, in the situation presentation stage, the fossil leaves were collected from the dicotyledon plants near school, and the LMA (Leaf Margin Analysis) climate inquiry activity. was presented as the learning goal. During the creative design stage, students were taught about geology and leaf fossils in the study region, and CLAMP input data (31 characteristics of morphotype and leaf architectural of fossil leaves) were given. In the emotional experience and new challenge stage, we collected leaf fossils for outdoor learning, explored paleoclimate with CLAMP method, and promoted climatic literacy in the process of discussing tendencies and causes of Cenozoic's climate change. The validity of the development program was assessed (CVI .84) as being suitable for development purpose in all items through the process of establishing reliability among expert panel. In order to apply the program to the high school, a pilot test was conducted to supplement the discrepancies and to review the suitability. The satisfaction rate of the participants was 4.48, and the program was complemented with their opinions. This study will enable high school students to have practical knowledge and reacting volition for climate change, and contribute to fostering students' climate literacy.

The primary objective of this study is to examine differences between the persons with recent onset and chronic mental illness in their family function; and analyze factors influence on the family function. The independent variables are divided into four sets: socio-economic, clinical, familial, and social characteristics. The subjects of this study are the 628 with mental disorders, and the sample was selected in Pusan and Gyeong-nam area. The findings of this study can be summarized as followed: The family with chronic mental illness showed higher family function in comparison with recent onset. Result of hierarchical multiple regression analysis show that age of onset, difference between ideal and reality in family function variable only influenced family function for the recent onset group, and activities of daily living, difference between ideal and reality in family function, caregiver's health, community support variables influenced family function for the chronic group. The results suggest a need for using different treatment approaches for recent onset versus chronic mentally disabled families. Implications for mental health social work practice for family with disabled are suggested.

This study focuses on the sleep pattern of the elderly people living in the community and its relationship to the occurrences of the depression and deterioration of the cognitive function. Our primary data is the raw data gathered by the Korean Ministry of Health and Welfare in 2008 in the National Senior Living Conditions and Well-being Needs Assessment Survey. The survey contained data from 12,087 people over 65 years of age living in the community. We have used the secondary data analysis method on this raw data to see if there exists correlation between age, gender, soundness of the sleep, total sleep time and the depression and the cognitive difficulties. Our study finds that the older a person is, the more trouble she has in sleeping. It also shows that too much sleep (in excess of 9 hours) and too little sleep (less than 6 hours) can both be linked to more occurrence of depression. Lack of restful sleep could also be linked to more frequent occurrence of depression and cognitive difficulties. Changes in the sleep pattern is not always pathological in elderly people. However, our study shows that it is important the primary health-care givers understand the role of sleep in elderly person's daily life. They should examine the elderly person's sleep pattern focusing on the quantity and the quality of sleep and develop programs suited for individuals to prevent and intervene sleep disorder.

Detecting probable Alzheimer's disease (AD) at an early stage is crucial in slowing the progression of the disease and initiating drug therapy for more effective symptom management. Therefore, this study aimed to identify linguistic features that allow us to distinguish between patients with AD and normal controls. This paper reports on characteristics of spontaneous speech in subjects in three stages of AD (questionable, mild, moderate) compared with education- and age-matched normal controls. Four components of speech were measured in Korean native speakers with AD and normal aging: speech tempo, hesitation (measured in seconds), rate of articulation errors, and rate of grammatical errors. The results revealed significant differences in most of these speech components among the four groups, including significant differences between normal controls and the questionable AD group in the areas of speech tempo and rate of grammatical errors. Phonological? articulatory ability was preserved in questionable AD, and grammatical ability was preserved in questionable and mild AD. Subjects with moderate AD were severely impaired in grammatical ability. Prospective assessments of spontaneous speech skills using a dialogue and picture-description task are useful in detecting the subtle, spontaneous speech impairments that AD causes even in its early stage.
