The market penetration of the smart phones has brought significant changes to the related industries. As the mobile phone market as well as the smart phone application market are growing rapidly, competition among small-size application developers has become severe. However, due to the severe competition and expensive market entry costs, the developers argue that it is necessary to develope the applications from the perspective of the users. However, studies on application development from the users' perspectives are still in the early stages and they have not provided various approaches. Therefore, based on the Open Coding method of Ground Theory, this study collected data on applications review from related communities and blogs of Korean web portal sites, and identified indices which users consider important when they use the applications. In addition, we conduct a comparative analysis between those indices by calculating their frequency of exposure. As a result, a total of 30 sub-categories of indicators such as amusement, controllability, versatility and ease of use appeared to be predominant to users and those lower categories were grouped into five categories; sensibility, design, technology, price, and social skills. The results of this study suggest to the application developers the guidelines of user oriented design and development. It can be used to develop the evaluation tool for application usability.

This is a case study with the objectives of performing an in-depth investigation of the development process, outcome, and the factors related to the development process of Jinggomdari-the self-help group for divorced single parents at Wolgye social welfare center. Document review, in-depth interviews of the member/practitioner/middle manager, and participatory observations were performed and qualitatively analyzed. The results showed that the development process of Jinggomdari consisted of 4 phases including initiation, formation of basis, growth, and expansion/independence. Two categories including 'nurturing abilities and growth as an individual or within families or communities' and 'beyond Jinggomdari, into society', 6 subcategories, and 31 concepts were derived as the outcome. In terms of the factors related to the development process and outcome, 6 categories including 'members participating with sympathy despite various issues', 'outstanding and stabilized leadership', 'commitment of the practitioners showing utmost efforts despite shortcomings', 'effective functions as the hub supporting the low-income divorced single parents families based on the institution's firm determination', 'mixed group showing cautious but synergistic effects', 'dilemma of managing the low-income divorced single parents self-help group and lack of manual for management', 20 subcategories, and 61 concepts were derived. Management issues concerning low-income divorced single parents' self-help group was discussed based on these results.

Categorization is very important for product design. Consumer's emotion become different according to a type of categorization, so design concept and design elements must be combined differently with difference of the emotion. Specially, categorization process is necessary if nowadays product line is enlarged, and a product differentiation is not clear. That is, designers decide on correct categories and a design concept based on similarity of emotion and have to provide to consumer-oriented design. The purpose of this study is to provide a design direction for Korean traditional sauce products after extracting consumers' sensitivity from the whole image of Korean traditional sauce and each images of the sauces-korean hot pepper paste, soybean paste, fermented soybeans paste, SsamJang, and soy sauce- and deciding categories of the each sauces based on the extracted sensitivities' similarity. In the result of this study, we knew that Korean traditional sauces didn't differentiate from consumers' preference images. In our empirical research, the research - emotional image survey on sauces - have conclusion that emotional image of "well-being", "tasty" have positive influence, but emotional image of "messy and dirty", "smelly" have negative influence. Therefore, we suggest that positive emotional images like "tasty" should be emphasized, but negative emotional images like "messy" should be eliminated for design and marketing strategy of Korean traditional sauces. This research will suggest the guideline for product design with respect to academic aspects and working-level aspects.

A super ensemble model was developed for the seasonal prediction of regional precipitation in Korea using the lag correlated large scale predictors, based on the empirical orthogonal function (EOF) analysis and multiple linear regression model. The predictability of this model was also evaluated by cross-validation. Correlation between the predicted and the observed value obtained from the super ensemble model showed 0.73 in spring, 0.61 in summer, 0.69 in autumn and 0.75 in winter. The predictability of categorical forecasting was also evaluated based on the three classes such as above normal, near normal and below normal that are clearly defined in terms of a priori specified by threshold values. Categorical forecasting by the super ensemble model has a hit rate with a range from 0.42 to 0.74 in seasonal precipitation.

The purpose of this study is to explore the subjective perception of college students' Internet addiction by applying photovoice method, a participatory research method. The subjects of the study were nine university students at G University. The data were analyzed by orientation, photo collection, photo selection, contextualizing and codifying according to the general photo voice research procedure.As a result, 15 sub-categories were derived based on the meaning of Internet addiction, the effects of Internet addiction on life, and how to get out of Internet addiction. The perception of the meaning of Internet addiction was divided into five categories: 'loss of self-regulation', 'habit without exit', 'disconnection from the world', 'loss of me', and 'voluntary prison'. The effects of Internet addiction on life were 5 categories: 'health deterioration', 'social isolation', 'broken daily life', 'anonymous violence' and 'my discovery and life extension'. In terms of how to get out of internet addiction, 'self-looking', 'new hobbies', 'nearby', 'reality meetings', and 'forced blocking' were derived. It suggested the discussion about Internet addiction viewed by college students and the implications of constructing a counseling program that can help to use the Internet correctly.

This study is designed to investigate social worker's experience in community practice at community welfare centers. Especially this study is conducted to identify the question; how do social workers experience community practice? For the study, data is collected from 11 social workers by depth interview. Using the Grounded theory, the data is analysed by open coding, axial coding, and selective coding. Finally the core category is become known that community practice is the piled up process of developmental experience throw willful efforts and various strategies under poor circumstances. The findings are as follows: (1) the experienced social workers seriously consider residents, community, social workers, and community welfare centers as the core participant in community practice. (2) the experienced community practitioners use various strategies on the whole process. (3) a system needs to be built to train community practitioners based on the cooperation of universities and community centers.

The purpose of this study is to examine the recovering gambling addicts' overcoming process on their hardships of life which hamper their recovery. For this study, we had one to one depth interview with 10 participants who had overcome their hardships of life after stopping gambling. The data gathered from the interviews were analysed following the grounded theory process suggested by Strauss and Corbin. As a result, 131 concepts were constructed, and they were classified into 32 subcategories and 14 category. We presented "overcoming of the hardships of life through the acceptance of reality and re-determination" as a core subject which connects the whole concepts. Based on the research outcomes, we proposed some policy and practice intervention methods such as economic self-support program, social security service, and triangle support system by counselor-family-peer recovering addicts.

The purpose of this study was to identify factors that affect the optimal selection of rehabilitation therapy and explore a processing model of rehabilitation decision-making for parents of children with cerebral palsy. A ground theory of Strauss and Corbin(1988)was used. Thus, collecting data was classified into open coding 140 concepts, 29 sub-categories and 8 categories. As a result of analysis, we identified that the main phenomenon was 'finding optimal therapy in trial and error' and parents experienced 6 stages including 'embarrassment', 'confusion', 'maximization', 'wandering', 'strategy', and 'balance'. Furthermore, 'rehabilitation-daily life balance' was a key category for continuation of treatment. This qualitative study discribed factors influencing determination of treatment and its continuation, and suggested a processing model of parents' decision- making for rehabilitation of their children.
