The purpose of this study is to examine whether family relationships of elderly single-person households affect community participation and whether these relationships differ by gender. Based on Baltes and Baltes (1990) 's selection, optimization, and compensation theory (SOC) and the argument that family members are a social capital by Prandini (2014), we test whether family relationships can affect community participation in old age. In order to verify this, single-person households were extracted from the 2017 National Survey of Living Conditions and Welfare Needs conducted by the Korea Institute for Health and Social Affairs (Male sample=370, Female sample=1770), multiple regression analysis were conducted with the dependent variables of friends·neighbors and the participation at Kyungrodang·welfare centers for the elderly. The results are as follows. In the case of men, family relations showed no significant effect on their participation in friends·neighbors, or Kyungrodang·welfare centers. However, in the case of women, the frequency of contact with family had a positive effect on the frequency of meeting friends·neighbors. Family contact frequency and child relationship satisfaction had a positive (+) effect on Kyungrodang·welfare center participation, while family meeting frequency had a negative effect on participation in Kyungrodang·welfare centers. For women, although Prandini's (2014) claim that family members are a social capital seems to be supported, it was found that the impact could vary depending on the type of community participation. In addition, practical discussions and suggestions were presented.

Call centers have become the prevalent contact points between companies and their customers. By virtue of recent advances in communication technology, the number and size of call centers have grown dramatically. As a large portion of the operating costs are related to the labor costs, efficient design and workforce staffing are crucial for the economic success of call centers. Therefore it is very important to determine the adequate number of agents. In this context, the workforce staffing level can be modeled as mathematical optimization problem using queueing theory. In this paper, we deal with an approximate analysis of an N-design call center with two finite queues and two types of reneging customers by using the state decomposition method. We also represent some numerical examples and show the impact of the system parameters on the performance measures of the call center.

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.

This study identifies 164 Korean medicine practitioners among the independence activists and describes the types and characteristics of their independence movements. Their occupations included apothecary pharmacist, herbalist, and medicine dealer. They originated from Gyeongbuk, Hamnam, Pyeongnam, and Gyeongnam, with a higher proportion of Hamnams compared to independence fighters. Their ages are concentrated in the 30s and 40s. Their movements are similar to those of independence heroes, in the order of domestic resistance, the March 1 Movement, and Manchurian resistance. The crimes are Security Law, Exorcism No. 7 of the 8th Reign of Daejeong, Public Order Maintenance Law, and attempted murder. In terms of sentences, the proportion of those sentenced to five years or more in prison is higher, and the proportion of those sentenced to less is lower. The above independence movements in Korean medicine practitioners are characterized by (1) the use of direct force, (2) long-term and planned struggle, (3) the provision of contact points and funding sources, (4) a nationalist line, and (5) low socialist-communist share.

Purposes: Prompt evaluation of routes and contact tracing are very important for epidemiological investigations of coronavirus disease 2019 (COVID-19). To ensure better adoption of contact tracing apps, it is necessary to understand users' expectations, preferences, and concerns. This study aimed to identify main reasons why people use the apps, appropriate services, and basis for voluntary app services that can improve app participation rates and data sharing. Methodology/Approach: This study conducted an online survey from November 11 to December 6, 2020, and received a total of 1,048 survey responses. This study analyzed the questionnaire survey findings of 883 respondents in areas with many confirmed cases of COVID-19. This study used a multiple regression analysis. Findings: Respondents who had experience of using related apps showed a high intention to use contact-tracing apps. Participants wished for the contact tracking apps to be provided by the government or public health centers (74%) and preferred free apps (93.88%). The factors affecting the participants' intention to use these apps were their preventive value, performance expectancy, perceived risk, facilitative ability, and effort expectancy. The results highlighted the need to ensure voluntary participation to address participants' concerns regarding privacy protection and personal information exposure. Practical Implications: The results can be used to accurately identify user needs and appropriate services and thereby improve the development of contact tracking apps. The findings provide the basis for voluntary app that can enhance app participation rates and data sharing. The results will also serve as the basis for developing trusted apps that can facilitate epidemiological investigations.

The purpose of this dissertation is to positively analyze the characteristics of job center consultants' interorganizational relations and factors that influence this linkage in order to better understand the employment service of South Korea. The material utilized for analysis was collected by surveying consultants and managers of 38 job centers and 364 middle managers while applying the method of hierarchical regression. The following is the summary of the research results. First, there is a difference in the influence factor between the number of consultant's organization linkage and frequency of contact. As seen from this result, if the number of organizations a consultant links is affected by the organization's objective working conditions such as the organization structure, position, and primary responsibilities, then the frequency of contact which indicates intimacy by frequent contact depends on the professional ability of the person in charge rather than objective conditions. Second, the analysis result of influence factors according to the type of organization also displayed different influence factors based on the type. Public organizations and economics related organizations are existent in all areas in the form of municipal offices, public corporation, the Chamber of Commerce and Industry, and labor organizations. Therefore, rather than the personal ability of the person in charge or the influence of other work environments, information of the organization and the actual activities of the head are more influential. On the other hand, private organizations embrace service organizations, employment target related organizations, corporations; they are differentially distributed, which is why they are more influential in organizational reform, decentralization, communication, and the professional ability of the person in charge is significantly influential.

In a contact-free society, online services are becoming more important than classic offline services. At the same time, the role of a contact center, which executes customer relation management (CRM), is increasingly essential. For supporting the CRM tasks and their effectiveness, techniques of process automation need to be applied. Quality assurance (QA) is one of the time and resource consuming, and typical processes that are suitable for automation. In this paper, a method of automatic quality evaluation for voice based consultations is proposed. Firstly, the speech in consultations is transformed into a text by speech recognition. Then quantitative evaluation based on the QA metrics, including checking the elements in opening and closing mention, the existence of asking the mandatory information, the attitude of listening and speaking, is executed. 92.7% of the automated evaluations are the same to the result done by human experts. It was found that the non matching cases of the automated evaluations were mainly caused from the mistranslated Speech-to-Text (STT) result. With the confidence of STT result, this proposed method can be employed for enhancing the efficiency of QA process in contact centers.

Ferrule is widely used as fiber optic connecters. In fiber-optic communications, the shape accuracy such as coaxiality and cylindricity of ferrule affects insertion loss. When coaxial grinding of ferrule supported by two pin, pin alignment and chucking accuracy are very important. In this research, the kinematic behavior of the ferrule center is investigated in the case where cone-shaped center pins and round circle hales which make contact with each other near the edge of the holes, using homeogenous coordinate transformation and numerical analysis. The obtained results are as follows: The alignment errors between center pins alone do not affect the rotation accuracy of ferrule. The alignment errors between center holes cause a sinusoidal displacement of ferrule. And the maximum displacement of ferrule centers increase in proportion to the center pin angle in the case of a fixed alignment errors

The orthogonal trajectories of the first tangents of the curve are called the involutes of x. The hyperspheres which have higher order contact with a curve x are known osculating hyperspheres of x. The centers of osculating hyperspheres form a curve which is called generalized evolute of the given curve x in n-dimensional Euclidean space ${\mathbb{E}}^n$. In the present study, we give a characterization of involute curves of order k (resp. evolute curves) of the given curve x in n-dimensional Euclidean space ${\mathbb{E}}^n$. Further, we obtain some results on these type of curves in ${\mathbb{E}}^3$ and ${\mathbb{E}}^4$, respectively.
