Even though automakers have actively been conducting studies on autonomous navigation thanks to the development and application of wireless Internet technology, the traffic accident has been kept unsolved. The causes of the accident are drowsy driving, a mistake of a driver, environmental factors, and a wrong road structure; Driving manner and characteristics of a driver among the causes are significantly influential for the accident. In this paper, a study to measure characteristics of zigzag driving that can be seen before an occurrence of an accident regarding traffic accidents that can be incurred while driving manually or autonomously was conducted. While existing studies measured zigzag driving based on characteristics of the change of lateral angular velocity by imaging techniques or driving manner on the first and second lane, this study proceeded to measure zigzag driving by setting a lateral moving distance and a critical value range by utilizing the value of a sensor.

As livestock diseases such as foot-and-mouth disease are highly infectious and likely to inflict nationwide damage, it is important to detect such diseases in advance. Infection of foot-and-mouth disease is determined in the field through examination of external symptoms such as rise in body temperature. However, as the disease is carried around initially by travelling veterinarians in some cases, it is critical to measure the body temperature of livestock to detect abnormal temperature pattern early on and transmit temperature reading data remotely to a veterinarian remotely to expedite decision. In this study, we have developed a telemedicine system designed to connect veterinarians and livestock farmers and measure the body temperature of Korean beef cattle with IR sensor module linked to ubiquitous ICT platform as a solution for controlling health conditions of Korean beef cattle and improving the efficiency of livestock farming operations at individual farm, regional, and national level by converging ubiquitous ICT platform and livestock farming practices. Successfully employing the state-of-the-art IT technologies of Korea, the system proposed herein is expected to make Korea's livestock farming industry more sustainable and help the nation to secure technological preeminence in the global livestock products market.

It has been reported that more than 10 percent of Korean elementary students are classified into ADHD (Attention Deficit / Hyperactivity Disorder). Major treatment of ADHD is medication. However, medication brings various kinds of side effects. Therefore, we need a way to improve attention leve, and lead children to voluntarily participate in it. With this purpose, we tried to develop a 3D tangible game to improve the children's attention level. To measure the level of attention enhancement, firstly we measured both the group average and the standard deviation of the measurement variables from the raw data gathered during the game play time. The measured value can be effectively used to measure the level of attention improvement of the children who might need treatment.

The growth of the older population is expected to further increase social problems associated with population aging, such as isolation, poverty, and depression. The emerging issues associated with the older population are also expected to provide further momentum on studies about the dwelling environment as factors that ensure the health of older people as well as improve their quality of life. Therefore, approaches for explaining the issues of the older age group should be diversified using a variety of factors and appropriate analytic tools. Studies on measuring depression have principally focused on assessing an objective self-report questionnaire, usually in a highly structured, textual form which may not reflect the cognitive impairment of older adults. The aim of this study was to define and measure dwelling depression among older adults in Korea. There are two specific hypotheses in this study as follows: (a) there will be statistically significant relationships with dwelling dissatisfaction and depression, and (b) dwelling depression tools containing text and images will be, respectively, assessment tools that have a good construct with content validity and reliability. In the first experiment, to define and measure dwelling depression, 301 people over 65 years old living in single and two-person households were surveyed using a text-based dwelling depression questionnaires from September 1-30, 2017. In the second experiment, to examine whether the projective image questionnaire could serve as a suitable replacement for the text-based questionnaires, the same participants were surveyed from January 22 to February 2, 2018. The results show that depression has a close correlation with dwelling dissatisfaction. In addition, the geriatric dwelling depression index (GDDI) based on the projective image was refined. Additionally, the projective image questionnaire has a close correlation with the text-based questionnaire. Finally, through ROC curve analysis, it was found that the projective image questionnaire can accurately predict a depression group. To this end, this preliminary study examined the validity of the projective image questionnaire in older adults to make this instrument feasible for older populations and to contribute to a profound understanding of geriatric depression due to the living environment. We hope they will provide a basis for further research on psychological diagnoses using projective images.

An index that evaluates the health level of a population group considering both death and loss of function due to disease is called a summary measure of population health (SMPH). SMPHs are broadly divided into life year indices and life expectancy indices, the latter of which comprise healthy life expectancy (HLE). HLE is included as a policy target in various national and regional level healthcare plans, and the term "HLE" is commonly used in academia and by the public. However, the overall level of understanding of HLE-such as the precise definition of HLE and methods of calculating HLE-still seems to be low. As discussed in this study, the types of HLE are classified into disability-free life expectancy, disease-free life expectancy, quality-adjusted life expectancy, self-rated HLE, and disability-adjusted life expectancy. Their characteristics are examined to facilitate a correct understanding and appropriate utilization of HLE. In addition, the Sullivan method, as a representative method for calculating HLE, is presented in detail, and major issues in the process of calculating HLE, such as selection of the population group and age group, estimation of death probability, calculation of life years, and incorporation of health weights, are reviewed. This study will help researchers to select an appropriate HLE type and evaluate the validity of HLE research results, and it is expected to contribute to the vitalization of HLE research.

The purpose of this study is to observe and analyze the Beijing dialect from the perspective of the lexicon. It sought to determine the lexical differences between the Beijing dialect and Putonghua. In the first part, it introduces the connection between the Beijing dialect and Putonghua and describes in details their individual developments in different historical stages. These imprints of the evolution of language in history have made distinctions between the Beijing dialect and Putonghua. The second part of this paper analyzes the lexical features of the Beijing dialect based on four aspects: the characteristic of word-formation, variant pronunciations of mono-syllabic words, usage of Measure words, and loanword from the Mongolian and Manchu language. First, in the basic Chinese vocabulary, there are about 47.11% of words that are different between the Beijing dialect and Putonghua. The differences between these words are mainly due to differences in partial morphemes, differences in the number of syllables, and the presence or absence of retroflex ending. Second, for the pronunciation of mono-syllabic words, the differences mainly occurs in tone sandhi, changes in finals or initials and dissimilation of the phoneme. Third, the characteristics of Measure words in the Beijing dialect use nouns indicating body parts. Fourth, most loanwords from the Mongolian or Manchu language are written in the way of phonetic loan characters. Some of the phonetic loan characters are associated with the meaning of the borrowing words, but some are not. The third part of this paper expounds on the direction of development of the Beijing dialect and Mandarin from the aspects of urban population structure; the people's attitudes toward language and the language environment in the Beijing dialect and Putonghua; and government policy intervention. In general, the vocabulary of the Beijing dialect is gradually losing its characteristics and becoming more and more like Putonghua.
