The objective of this study is to find out the relation between infant teacher attachment or infant gesture and infant language development. The study was conducted with infants aged between 18 and 24 months and their 84 teachers of 63 home day care centers and infant day care centers in J city, Jeollabukdo. The results of the study are as follows. First, there was positive correlation between infant teacher attachment and infant language development. Looking at the types of infant teacher attachment showed that positive emotion, contact-seeking, self-sacrifice genialities, approach-seeking, solidarity, and expectation had positive correlation with receptive and expressive language, protection had positive correlation with receptive language, and only indifference had negative correlation with receptive language. Second, of sub-factors of infant gesture, directive gesture had negative correlation with receptive language, and customary and representational gesture had positive correlation with expressive language. Third, according to the results of the study of the effects of infant teacher attachment and infant gesture on infant language development, contact-seeking had the largest effect. Looking at the types of infant language development showed that contact-seeking had the largest effect on receptive language, and solidarity had the largest effect on expressive language. The results of the study showed that infant teacher attachment had larger effects on infant language development than infant gesture. It is expected to be used as useful materials to improve communicative abilities of infant teachers interacting with infants for infant language development.

An object oriented programming(OOP) framework is presented to solve plane elastostatic contact problems by means of the boundary element method(BEM). Unified modeling language(UML) is chosen to describe the structure of the program without loss of generality, even though all implemented codes are written with C++. The implementation is based on computational abstractions of both mathematical and physical concepts associated with contact mechanics involving geometrical nonlinearities and the corner node problems for multi-valued traction. The overall class organization for contact analysis is discussed in detail. Numerical examples are also presented to verify the accuracy of the developed BEM program.

No language can be separated from other languages and exist independently. When a language comes in contact with a foreign culture, they continuously affect each other and bring changes. Hallyu boom(Korean wave), which was derived from the emergence of K-drama and K-pop due to rapid developments in global scientific technologies and digitization after the 90's, affected the Chinese language. As a result, neologisms that are derived from the Korean language are being commonly used for making exchanges and becoming social buzzwords. Neologisms derived from Korean reflect the effects and results of language contact between the two languages. We examined the background and cause of Chinese neologisms derived from Korean based on the sociocultural factors and psychological necessity, and explained neologisms by using four categories of transliteration, liberal translation, borrowing Korean-Chinese characters and others. Despite having the issue of being anti-normative during the process of coining new words, neologism enriches Chinese expressions and is a mirror for social culture that reflects the opinions and understandings of young Chinese people who pursue novelty, change, innovation and creativity in linguistic aspects. We hope that it will serve as an opportunity for the young people in Korea and China to change their perceptions and become more friendly by understanding each other's language, culture and by communicating. We also expect to provide assistance in regard to teaching and learning the applications of Korean-Chinese language fusion at Chinese education fields.

This paper investigates the load sharing of double circular arc helical gears considering the influence of assembly errors. Based on a load sharing formulae, a three-dimensional finite element tooth contact analysis (TCA) is implemented with commercial software package ANSYS. The finite element grid for the double circular arc gear contact model is automatically generated by using the APDL (ANSYS Parameter Design Language) embedded in ANSYS. The realistic rotation of gears is achieved by using a coupling degree-of-freedom method. Numerical simulations are carried out to exemplify the proposed approach. The distribution of contact stress and bending stress under specific loading conditions are computed and compared with those obtained from Hertz contact theory and empirical formulae to demonstrate the efficiency of the proposed load sharing calculation formulae and TCA approach.

This study aims to examine the relationship between mothers' attachment levels, types of verbal control, and infants' language development. The selected participants comprised 224 infants, aged 24-35 months and their mothers (224) at 25 long day care centers located Goyang-si, Gimpo-si in Gyeonggi-do, Incheon and Seoul. The major findings of this study were as follows. First, there were significant differences in mothers' attachment levels, types of verbal control, and infants' language development depending on the mothers' employment status. Secondly, to assess the relative influences of two variables which were significantly associated with infants' language development, the sociodemographic variables of mothers and infants, including infants' age and mothers' employment status, were controlled in order to conduct hierarchical regression analysis. The results revealed that imperative-oriented verbal controls, person-oriented verbal controls, and contact seeking all influenced infants' overall language development.

The geographical characteristics of Yeongdong(永同) the southernmost part of the Chungcheongbukdo province, has attracted attention among the academic circle as one of the dialectal contact regions since it adjoins the Gyeongsang and Jeolla dialects. Unlike the local language in Mooju (Jellado dialect) adjacent to the Southwest part, the local language in Yeongdong is quite different from that of Kimcheon (Gyeongsang dialect). More specifically, it is noteworthy that the boundary line of the Gyeongsang dialect is found in this region, which is different from the administrative division. In other words, the local language in Yeongdong is divided into the Chungcheong dialect and the Gyeongsang dialect, and furthermore each dialect region still has the characteristics of the other region's dialect. For example, the phonological structure of Yeongdong Chungcheongdo dialect has very unique characteristics of the fudged dialect, which is seemingly influenced by the Gyeongsang dialect. The present study is to define the bottom boundary line of the southeast area of the Chungcheong dialect by identifying the boundary line between the Gyeongsang dialect and the Chungcheong dialect, and to clarify its specific sound system generated by the contact of these two dialects. For this, the author collected and analyzed data of the local language around Yeongdong and adjacent areas. It was found that Cheongwha-ri, Deokjin-ri, and Sanjeo-ri at Yeongsan-myeon, and Mugeunjeom, Sangga-ri, and Jungga-ri at Yeongdong-eup, among the regions that belongs to Chungcheong dialect within the local language of Yeongdong, show the characteristics of the Gyeongsang dialect. Accordingly, the western areas of these villages become the southeast boundary line of the Chungcheong dialect. Also, the unique phonological characteristics of the Yeongdong Chungcheong dialect is affected by the Gyeongsang dialect, among which "rhythms, y deletion, nasal phoneme deletion, and w deletion" appeared. It is thought to be the unique fudged dialectal phenomenon that appeared only in this region. The research result is expected to be of some help in finding out various aspects of dialectal contacts as well as clarifying the phonological features of the local language in Yeongdong, and thereby contributing to exact divisioning of the Chungcheong dialect.

This paper aims to investigate a novel affix prevalently and productively used in social media, which is assumed to be borrowed from English into Korean loanblens. The novel affix is composed of a prefix-like and a suffix-like elements, but it seems to be distinguished from other regular combinations of a prefix and a suffix. In analyzing the affix, we attempt to highlight its peculiarities of the affix with empirical data. First, the seemingly borrowed affix does not behave like affixes found in the donor language (English) or the recipient language (Korean) from a linguistic point of view. Both languages have circumfixation rarely available in productive word-formation processes. Second, no regular assimilation rules of Korean apply to the affix boundary, which would otherwise be mandatory to such syllable contact contexts. Last but not least, the affix form has no correspondence to the donor language, and therefore it is claimed to be derived through secretion and taken as a case of pseudo-anglicisms.
