The purchase of business services is a growing activity among finns but with little appreciation that the purchase of a service requires a modification of the decision process developed for the purchase of material goods. A taxonomy for purchasing business services is developed to create a matrix with company involvement and focus of service as dimensions. Business services are classified according to their focus on three aspects of the finn: property, people, and core business. Business services are also classified according to the degree of company involvement: high company involvement and low company involvement. A number of propositions are formulated based on insights derived from this taxonomy. The taxonomy results in six business service cells: facility support, equipment support, employee support, employee development, core business facilitator, and professional. Implications for managers considering a purchase in each category are explored. This study tests the research hypotheses delineated from the classification model and the purchasing process of business services. The strategic implications are suggested based on the findings for each cell of the classification model. This study concludes with a research agenda for further studies.

This study aimed to explore the moderating effect of social support resources on the life satisfaction and caregiving burden of family caregivers taking care of the elderly in long-term care services. The study participants were selected from among the family caregivers utilizing 30 home care centers in Seoul, Korea. Of the candidates who agreed to participate in the study, 250 caregivers who had supported the elderly at home for at least 6 months were selected. The data collected were analyzed using SPSS ver. 21.0. The study findings were as follows. First, the whole family caregivers' caregiving burden of family caregivers was found to be slightly higher than the median value. More specifically, the physical burden was the heaviest, followed by the family relationship burden, the social activity burden, the emotional burden, and the financial burden. Social support resources and life satisfaction were found to be a little bit higher than the median value. Second, the variables that statistically significantly increased life satisfaction, starting with the strongest effect, were a lower psycho emotional burden, greater informational support resources, a lower economical burden, greater emotional support, a younger caregiver age, a higher monthly income, and a shorter care period. Third, informational support resources were found to have a moderating effect on the relationship between the support burden and life satisfaction. The more the participants used the informational support resource subcategory of the social support resources, the narrower the life satisfaction decrease, even though the caregivers felt a support burden. Informational support resources appear to have a statistically significant buffering effect.

Enzymatic catalysis has been pursued extensively in a wide range of important chemical processes for their unparalleled selectivity and mild reaction conditions. However, enzymes are usually costly and easy to inactivate in their free forms. Immobilization is the key to optimizing the in-service performance of an enzyme in industrial processes, particularly in the field of non-aqueous phase catalysis. Since the immobilization process for enzymes will inevitably result in some loss of activity, improving the activity retention of the immobilized enzyme is critical. To some extent, the performance of an immobilized enzyme is mainly governed by the supports used for immobilization, thus it is important to fully understand the properties of supporting materials and immobilization processes. In recent years, there has been growing concern in using polymeric materials as supports for their good mechanical and easily adjustable properties. Furthermore, a great many work has been done in order to improve the activity retention and stabilities of immobilized enzymes. Some introduce a spacer arm onto the support surface to improve the enzyme mobility. The support surface is also modified towards biocompatibility to reduce non-biospecific interactions between the enzyme and support. Besides, natural materials can be used directly as supporting materials owning to their inert and biocompatible properties. This review is focused on recent advances in using polymeric materials as hosts for lipase immobilization by two different methods, surface attachment and encapsulation. Polymeric materials of different forms, such as particles, membranes and nanofibers, are discussed in detail. The prospective applications of immobilized enzymes, especially the enzyme-immobilized membrane bioreactors (EMBR) are also discussed.

The export of domestic public services to overseas markets contains many potential obstacles, stemming from different export procedures, the target services, and socio-economic environments. In order to alleviate these problems, the business incubation platform as an open business ecosystem can be a powerful instrument to support the decisions taken by participants and stakeholders. In this paper, we propose an ontology model and its implementation processes for the business incubation platform with an open and pervasive architecture to support public service exports. For the conceptual model of platform ontology, export case studies are used for requirements analysis. The conceptual model shows the basic structure, with vocabulary and its meaning, the relationship between ontologies, and key attributes. For the implementation and test of the ontology model, the logical structure is edited using Prot$\acute{e}$g$\acute{e}$ editor. The core engine of the business incubation platform is the simulator module, where the various contexts of export businesses should be captured, defined, and shared with other modules through ontologies. It is well-known that an ontology, with which concepts and their relationships are represented using a shared vocabulary, is an efficient and effective tool for organizing meta-information to develop structural frameworks in a particular domain. The proposed model consists of five ontologies derived from a requirements survey of major stakeholders and their operational scenarios: service, requirements, environment, enterprise, and county. The service ontology contains several components that can find and categorize public services through a case analysis of the public service export. Key attributes of the service ontology are composed of categories including objective, requirements, activity, and service. The objective category, which has sub-attributes including operational body (organization) and user, acts as a reference to search and classify public services. The requirements category relates to the functional needs at a particular phase of system (service) design or operation. Sub-attributes of requirements are user, application, platform, architecture, and social overhead. The activity category represents business processes during the operation and maintenance phase. The activity category also has sub-attributes including facility, software, and project unit. The service category, with sub-attributes such as target, time, and place, acts as a reference to sort and classify the public services. The requirements ontology is derived from the basic and common components of public services and target countries. The key attributes of the requirements ontology are business, technology, and constraints. Business requirements represent the needs of processes and activities for public service export; technology represents the technological requirements for the operation of public services; and constraints represent the business law, regulations, or cultural characteristics of the target country. The environment ontology is derived from case studies of target countries for public service operation. Key attributes of the environment ontology are user, requirements, and activity. A user includes stakeholders in public services, from citizens to operators and managers; the requirements attribute represents the managerial and physical needs during operation; the activity attribute represents business processes in detail. The enterprise ontology is introduced from a previous study, and its attributes are activity, organization, strategy, marketing, and time. The country ontology is derived from the demographic and geopolitical analysis of the target country, and its key attributes are economy, social infrastructure, law, regulation, customs, population, location, and development strategies. The priority list for target services for a certain country and/or the priority list for target countries for a certain public services are generated by a matching algorithm. These lists are used as input seeds to simulate the consortium partners, and government's policies and programs. In the simulation, the environmental differences between Korea and the target country can be customized through a gap analysis and work-flow optimization process. When the process gap between Korea and the target country is too large for a single corporation to cover, a consortium is considered an alternative choice, and various alternatives are derived from the capability index of enterprises. For financial packages, a mix of various foreign aid funds can be simulated during this stage. It is expected that the proposed ontology model and the business incubation platform can be used by various participants in the public service export market. It could be especially beneficial to small and medium businesses that have relatively fewer resources and experience with public service export. We also expect that the open and pervasive service architecture in a digital business ecosystem will help stakeholders find new opportunities through information sharing and collaboration on business processes.

Purpose: This study examined the perceived quality of life of families of individuals with developmental disabilities who regularly participate in physical activities. It also explored differences in the quality of family life based on variables such as family relationships, family income, gender, disability type, and age. Methods: A survey was administered to 69 family members of individuals with developmental disabilities who regularly participate in physical activities. The collected data were analyzed using descriptive statistics, independent samples t-test, and one-way analysis of variance. Results: The average overall quality of life for families of individuals with developmental disabilities who participate in continuous physical activities was 3.49. After analyzing each subtype, psychological health was found to be 3.91, the burden for people with developmental disabilities was 2.75, community participation was 3.76, cohesion was 3.83, and openness was 3.49. No statistically significant differences were found in family relationships or family classes, disability type, age, or gender of the individuals with developmental disabilities across the variables. Conclusion: When planning service development and support to improve the quality of life for families of individuals with developmental disabilities, it is necessary to develop systematic programs at the family level rather than providing support based on various variables.

The recent emergence of smart phones, wearable devices, and even the IoT concept made it possible for various objects to interact one another anytime and anywhere. Among many of such smart services, a smart home service typically requires a large number of sensors to recognize the residents' activities. For this reason, the ideas on activity recognition using the data obtained from those sensors are actively discussed and studied these days. Furthermore, plenty of sensors are installed in order to recognize activities and analyze their patterns via data mining techniques. However, if many of these sensors should be installed for IoT smart home service, it raises the issue of cost and energy consumption. In this paper, we proposed a new method for reducing the number of sensors for activity recognition in a smart environment, which utilizes the principal component analysis and clustering techniques, and also show the effect of improvement in terms of the activity recognition by the proposed method.
