The Association between myofascial pain syndrome and some tests was assessed in a cross-sectional study of 904 female telephone operators using video display terminals(VDTs). 105 cases were diagnosed as Myofascial pain syndrome with symptom questionnaire, laboratory examination and physician's physical examination and 550 controls were defined to show only musculoskeletal symptoms using NIOSH symptom criteria. Data on demographics, musculoskeletal symptom and visual analogue scale(VAS) were obtained by questionnaire. Anthropometric measurements, pressure pain threshold, Grip & Pinch strength and laboratory test were conducted. No significant difference between case and control at comparing of demographics, occupational history and body measurements were observed. But, Grip strength, pressure pain threshold and VAS showed the statistical difference between case and controt. Age, pressure pain threshold of Rt. Upper trapezius and VAS were associated with myofascial pain syndrome in multivariate logistic regression analysis. This results suggest that, to diagnose of myofascial pain syndrome, the consideration of the objective aspects among patients' subjective symptom complaints through the VAS and pressure pain threshold is required.

This article describers the field testing of the task-centered case management model for practice with the elderly clients in the community. Six social workers in three community center applied task centered. model to 12 elderly in community. The model tested in the field trial led to positive results. The results of task completion and problem change indicate that including elderly clients in all steps from identifying problems to suggesting and implementing tasks are important. Target problems and tasks which clients indicate gained high accomplishment. Task-centered interventions provided an intensive period of service that helped clients work on immediate problems. Moreover, they helped clients actively participate in decision making processes and in problem solving activities. Although the task centered approach is a short tenn intervention, the analysis of the field trial suggests that it can be integrated with an approach that is a long tenn in nature through re contract for different problems or unresolved problems. Several suggestion can be made to apply task-centered model for elderly in Korea. First, since one social worker handles over 60 cases, this approach can be used more effectively for new case or the elderly who needs intensive help. Second, preparing and sharing contract with client should be encouraged to help both client and social workers. Also until the social workers are familiar with this approach, there should be an intensive supervision to monitor their activities. Third, it is important to make task planner for Social workers who is working with elderly in community. Task planner is the guide line books to show steps to solve similar problems. Fourth, more efforts should be made to make resource directory in the community as well as in Korea. Fifth, case managers who handle family problems and other personal conflicts should be more trained to be confident to deal with these problems.

The main purpose of this study is to understand the socio-cultural adaptation and life-styles of the Chinese and Korean immigrants in Vancouver, Canada. Of interest are the immigration policies of the Canadian government and formation of the Chinese and Korean minority societies in Vancouver. Attention is given to estimating the size of the Korean population in Vancouver, utilizing the listings of telephone directory and the proportion of surname Kims in the Korean population. This paper focuses on explaining the distinctive adaptation patterns and socio-cultural characteristics of the Chinese and Korean immigrants. A conceptual scheme of socio-cultual adaptation of the minority immigrants, which is hypothesized as a function of the participation to the host society and the cultural identity, is also developed in this paper. Findings of the analysis suggest that the Chinese and Korean population in Vancouver witnessed a rapid growth since the mid 1980s, when the Canadian government launched the immigration programs for investors and entrepreneurs. It appears that the Chinese and Korean immigrants hold strong ethnic identity and maintain cultural traditions and life-styles of their own. While Chinese immigrants are characterized by active participation to the host society, Korean immigrants tend to confine themselves to the Korean enclave, and thus keep a certain distance from the host society. This appears to be particularly true for the Koreans who immigrated with a status of investor or entrepreneur. As the key force behind the ethnic differences in their adaptation, the role of voluntary associations is stressed. Finally, the future prospects of the Chinese and Korean societies and their acculturation are discussed in this study.

Since most CAD tool companies are carrying out very expensive license policies, designers are sharing CAD tools with a limited number of licenses within a design working or research group. It is important to share and use them efficiently, because CAD tool licenses are very valuable resources. Designers should know CAD tool license information such as available number of licenses, types, and configuration methods to use CAD tools properly in their group. Usually, this information is provided by managers who administrate CAD tool license servers in the specific design group. In the previous CAD tool licenses sharing methods, designers have to get CAD tool license information manually and setup the environments with their own hands, If a new designer comes into the design working group, the designer wastes unnecessary time and effort due to these manual processes. As a result, designer's productivity and utilization of CAD tools will decrease. Besides, managers also waste their time and effort, since they should provide CAD tool license information manually to each desiEner. In this paper, we present a more efficient scheme to share CAD tool licenses based on directory service. The proposed method automates not only the communication processes between managers and designers, but also the license configuration steps. We expect this scheme will reduce time and effort of designers and managers as well as enhance the utilization of CAD tools.

The Semantic Web and its related technologies have been opening the era of information sharing via the Web. There are, however, several huddles still to overcome in the new era, and one of the major huddles is the issue of information integration, unless a single unified and huge ontology could be built and used which could address everything in the world. Particularly in the e-business area, the problem of information integration is of a great concern for product search and comparison at various Internet shopping sites and e-marketplaces. To overcome this problem, we proposed an ontology-driven mapping algorithm between heterogeneous product classification and description frameworks. We also peformed a comparative evaluation of the proposed mapping algorithm against a well-Down ontology mapping tool, PROMPT.

In mobile cellular network the ever-changing location of a mobile host necessitates the continuous tracking of its current position and efficient management of location information. A database called Home Location Register(HLR) plays a major role in location management in this distributed environment, providing table management, index management, and backup management facilities. The objectives of this paper are to identify the p개blems of the current HLR system through rigorous analysis, to suggest solutions to them, and to propose a new architecture for the HLR system. In the HLR system, a main memory database system is used to provide real-time accesses and updates of subscriber's information. Thus it is suggested that the improvement bemade to support better real-time facilities, to manage subscriber's information more reliably, and to accommodate more subscribers. In this paper, I propose an efficient backup method that takes into account the characteristics of HLR database transactions. The retrieval speed and the memory usage of the two-level index method are better than those of the T-tree index method. Insertion md deletion overhead of the chained bucket hashing method is less than that of modified linear hashing method. In the proposed backup method, I use two kinds of dirty flags in order to solve the performance degradation problem caused by frequent registration-location operations. Performance analysis has been performed to evaluate the proposed techniques based on a system with subscribers. The results show that, in comparison with the current techniques, the memory requirement is reduced by more than 62%,directory operations, and backup operation by more than 80%.

In order to prevent the national wide spread of the COVID-19 virus, the government enforces to use an electronic access registration system for public facilities to effectively track and manage the spread. Initially, there was a lot of hassle to write a directory, but recently a system for creating an electronic access list using QR codes, what is called KI-Pass, is mainly used. However, the procedure for generating a QR code is somewhat cumbersome. In this paper, we propose a new electronic access registration system that does not require QR code. This system effectively controls the suspicious visitor by using a mask wearing discriminator which has been implemented using deep learning technology, and a non-contact thermometer package. In addition, by linking the beacon, a short-range wireless communication technology, and the visitor's smartphone application, basic information of the facility visitor is automatically registered to KDCA through the server. On the other hand, the user access information registered in the server is encrypted and stored, and is automatically destroyed after up to 4 weeks. This system is expected to be very effective in preventing the spread of other new infectious diseases as well as responding to the coronavirus which is recording a high spread worldwide.

Social enterprise has moved from periphery to take center stage. Social enterprises are a truly global phenomenon and associated with solving social problems with business approaches. While the numbers of social enterprises have grown and their impact is likely to continue to do so, it would be dangerous to assume that the revolutionary momentum will automatically continue, because social enterprise faced sustainability challenges. This study collected the data from directory of Korean Social Enterprise to conduct a quantitative research on the growth of social enterprise in South Korea. This study conducted longitudinal analysis of 491 social enterprise certified between 2007 and 2010, of economic performance with financial index and social impact with employment structure. Though global financial crisis, Korean social enterprises show that there is a considerable increase in all of quantitative and qualitative aspects. Korean social enterprises have provided meaningful work to those normally excluded from the labour market and tried to raise their life of working. In the future, Korean social enterprises should find a way to balance social and financial performance and ensure the sustainability of the business.

ENUM(tElephon NUmbering Mapping) is protocol that brings convergence between PSTN Networks and IP Networks using a unique worldwide E.164 telephone number as an identifier between different communication infrastructure. The mechanism provides a bridge between two completely different environments with E.164 number; IP based application services used in PSTN networks, and PSTN based application services used in IP networks. We propose a new way to organize and handle ENUM Tier 2 name servers to improve performance at the name resolution process in ENUM based application service. We build an ENUM based network model when NAPTR(Naming Authority PoinTeR) resource record is registered and managed by area code at the initial registration step. ENUM promises convenience and flexibility to both PSTN and IP users, yet there is no evidence how much patience is required when users decide to use ENUM instead of non-ENUM based applications. We have estimated ENUM response time, and proved how to improve performance up to 3 times when resources are managed by the proposed mechanism. The proposition of this thesis favorably influences users and helps to establish the policy for Tier 2 name server management.

The purpose of this study is to analyze the first edition of Brown's Subject Classification and to understand the implications of today's library classification. For this purpose, the first edition of the Subject Classification published in 1906 was analyzed. The analysis results are divided into three main areas. First, SC is divided into eleven main classes and each class is subdivided into enumerated subdivisions from 000 to 999. Second, As a method of synthesizing the classification numbers, there were three methods of synthesis. There was a flexibility to insert a new classification number at the appropriate location when a new topic that does not appear in the main table appeared. Implications for classification studies can be divided into four main categories. First, SC proposed a method of classification number synthesis for composite topics, which is an innovative method that was not available in previous library classification. Second, the subject matter was explained in various aspects through the operation of auxiliary tables supporting the facets. Third, it is possible to easily insert a new topic into the classification system by using the SC that can have a flexible classification system for each library, or to use a short classification number according to the size of the library collection. Fourth, it provided a directory that can be considered as access points for digital materials.
