This study investigated the key factors affecting online relational intimacy in the context of SNS. Based on the use and gratification theory, self-presentation, relationship formation and information searching were identified as the main needs of SNS usage. These needs were expected to influence online relational intimacy through user satisfaction, subjective well-being, and disclosing information behaviors. The theoretical framework was validated by a longitudinal method. Hypotheses were tested by using the partial least squares to data from 199 Facebook users. Self-presentation and information searching had a significant impact on both user satisfaction and subjective well-being. However, relationship formation did not significantly affect both user satisfaction and subjective well-being. User satisfaction had a significant direct effect only on online relational intimacy. Subjective well-beings played a significant role in enhancing both disclosing information behaviors and online relational intimacy. Finally, it has been found that disclosing information behaviors are a key factor in enhancing online relational intimacy. The results of this study are expected to provide academic and practical implications for the key antecedents of online relational intimacy.

To support advanced collaboration among knowledge workers distributed geographically, there have been extensive researches under the scope of ubiquitous computing environments. Especially, to cope with several known problems in traditional room-based collaboration environments such as uncomfortable sharing of visuals and documents and difficult operation of collaboration tools, several conceptual frameworks are designed and prototyped. Focusing on practical and interactive collaboration with remote nodes, in this paper, we conceptually design an agent-based service composition model for multi-party collaboration environments. The proposed model is designed to automatically discover and combine services to achieve given tasks in a collaboration environment by using high-level user commands (without the knowledge of internal architecture). Based on the service composition model, we develop a multi-agent-based management toolkit for multi-party collaboration environments. It provides easy-to-use GUI to operate various services in an environment and perform service composition algorithm to discover appropriate services and combine them. To explore the possibility of the toolkit we implement collaboration services to support video conference by using the toolkit.

In this paper, I try to help the business operation so that they could continue the desirable operation despite the unfavorable conditions. It is important to reinforce for corporate growth various support measures to generate profits. However, if they are involved in criminal activities such as slush fund creation, they will have to deal with them separately. As a result, To raise awareness helps to keep the company running. Recently, the companies are in a poor condition due to overseas migration. If a company does not create profits by doing business, it is a burden to continue operating and it will eventually be hard to support and destroy. The corporate crime and white-collar crime are mostly similar types, mainly because they occur in the industry. The corporate crime proceeds throughout the company and ultimately translates into corporate profits. The white-collar crime, on the other hand, is a profitable part of the individual. In the process of generating profits, the purpose and management method of slush funds is an important issue in judging whether illegal immorality of business is intended or not. In addition, in the case of the corporate crime, it seems necessary to identify the types of slush fund raising activities in addition to the investigations of the accomplices and clinical investigations, and to apply efficient investigation methods on a case-by-case basis. At present, many companies frequently migrate overseas due to the influence of domestic regulations. In this process, if it is involved in crime such as a borrowing accounts or the purpose of slush fund creation should be treated separately.

Objectives: The purpose of this study was to develop new meal planning tools for a nutritionally balanced diet. Methods: Based on the food exchange list for diabetes, we adjusted the food group classification system to reflect the suggested nutritional factors for chronic disease prevention and health promotion. We developed a nutritionally balanced dietary profile for adults and compared it with the dietary reference intakes for Koreans (KDRIs) and the food pattern recommended by the Korean Diabetes Association. Results: The newly developed menu planning tools are the LOHAS food exchange table and the LOHAS food pattern. Our recommended daily 1,800 kcal dietary composition for adults is as follows: The carbohydrate food group consists of 4 'whole grains', 3 'refined grains', 2 'sugars', 9 'vegetables', 3 'starchy vegetables', 2 'fruits' and 1 'high sugar fruits'. The protein food group includes 3 'plant protein foods', 3 'animal protein foods (low-fat)', and 1 'animal protein foods (high-fat)'. The fat food group consists of 2 'oils and nuts' and 1 'solid fats'. The total number of calories is estimated at 1,840 kcal and the energy ratio is 62% carbohydrate, 18% protein, 20% fat, 6.8% saturated fat and 13.2% sugars. Using the LOHAS food exchange table, it is possible to estimate values of saturated fat, unsaturated fat, dietary fiber, and sugars besides carbohydrate, protein and fat. It is also possible to compose a dietary design considering carbohydrate, sugars, saturated fat and dietary fiber. The LOHAS food pattern provides benefits for the management of both institutional food services and individual meals, as it can help reduce the levels of saturated fat and sugar intake and help develop healthy meals rich in unsaturated fats and dietary fiber. Conclusions: The LOHAS food exchange table and LOHAS food pattern are expected to be practical tools for designing and evaluating nutritionally balanced diets.

This study is intended to investigate if the standard of vocational rehabilitation service could be solely determined by medical standard for disability definement and to find out what alternatives are available to resolve practical problems for those who are not identified as the severely disabled by the disability definement but do experience severe handicaps at work. Through the literature review, the researcher argued that the concept of 'functional limitation' would be a criteria, and thereby applied Modified Barthel Index to measure the degree of functional limitation. In view of researching the relationship among physical impairment, functional limitation, and job status based on 381 cerebral palsied, variables such as the type of cerebral palsy and the part of paralysis, have neither direct nor indirect influence to the job status; however, the pain and the mobility have indirect effects, and the ability of self-management has direct effect on the job status. The researcher concluded that future research about disabilities needs to provide a serious thought on what it is to be defined as 'disabilities', as well as to focus on further research conceptualizing the degree of physical 'functional limitation'.

This article reviews 20 empirical studies that have focused on the organizational effectiveness of social welfare organizations since 1980. The purposes of this study were to understand the organizational phenomena of social welfare organizations, to offer practical implications for organizational management and to propose direction for the further researches. Special attention has been paid to identify 1) subjects of research 2) approach and criteria of organizational effectivess and 3) critical factors that impact on organizational effectiveness. The results showed that 1) most of researches utilized samples from social welfare community centers and assisted-living facility, 2) many researches focused on internal process approach and used diverse criteria of organizational effectiveness 3) collective developmental culture, decentralized structure, transformational leadership, open relationship between organization and external environment were critical factors of organizational effectiveness. The review suggests that social welfare managers should practice diverse approach based on vision, purpose and developmental stage of each organization. The managers also should implement more conscious efforts to make supportive and fair work environment where all employees feel valued and can demonstrate their maximum potential and to respond to task environments more proactively. Further research should be conducted from diverse organizations using various research methods. More comprehensive empirical model and multidimensional measure of organizational effectiveness need to be developed.

When the number of items of same type of industrial property is quite large, calculating depreciation for a group of such item may be more efficient than depreciating each item separately. Also, predicting the service life of a specific individual unit is very difficult to do with any degree of accuracy. Estimating the probable average service life (PASL) of many units (or dollars) is not an easy task; however, an average life of many units can probably be predicted with a much higher degree of accuracy than the life of some particular unit. Using the average of many units allows for some units having relatively short lives and some units having relatively long lives without specifying whether a particular unit will have a short or a long life. If the life of each vintage in an account are not estimated, then the broad group procedure can be used. The broad group procedure depreciates the several vintage in an account as a single group. The PASL for this procedure is the estimate of the average of lives of the individual dollars in the group. If the estimated PASL's of the vintages are not the same, then a weighted average PASL would have to be calculated for each calendar year. In this paper, we illustrate the calculations of accrual rates and the annual depreciation charge for each of the calendar years by the broad group depreciation procedure.

This paper has focused on the middle term process planning around quays based on the prefixed long-term plan of the product mixed ships. Recently, the order rate of high add-value ships in domestic shipyards has been sharply increased and the spending time at quays is accordingly on an increasing trend. For proper and practical process planning related to quays, it has to be closely connected with a long-term plan and product calendar, erection network and result of ship allocation around quays. Moreover, it is also required to include the integrated consideration of the whole process of a yard, each ship, and each team respectively. The most distinguishing feature of this study is that it would run on the ship allocation simulator and GIS framework in order not to be limited to the specific one yard and the readers can figure out the optimization formulation containing the work load leveling and a different approach from PERT/CPM. The proposed approach reflected all requirements from the department of process planning and management in a shipyard, and the analysis of the results has explained its performance of the optimization result with the examples of total 43 ships under construction from 2008 to 2013.
