The study aims to define the career competency of HRD practitioners based on an intelligent career framework. This intelligent career framework has been described as having been achieved by the accumulation of career capital through the three ways of knowing, including knowing why, knowing how, and knowing with whom. The data were collected from the interviews with 15 HRD practitioners. Semi-structured interviews were used to collect data from the HRD practitioners. For the orientation about the interview, the researcher explained the importance of gathering data about the personal experiences of the respondents on their work and career. After that explanation, the researcher asked several questions based on the pre-structured interview guide. The data collected were qualitatively analyzed on the basis of the intelligent career framework. Based on the analysis of the interviews, the subcategories of each way of knowing competency were identified. For the knowing why, identity, credibility, and career clarity were identified. The subcategories of knowing how are remaining updates, hard skills, and soft skills, while the subcategories of knowing with whom are personal networking and professional networking. The interdependency among the three career competencies was found. The findings provide theoretical implications of applying an intelligent career framework.

Purpose: This study was conducted to define the concept of stress in siblings of childhood cancer patients. Methods: The hybrid model was used to perform the concept analysis of stress in childhood cancer patients' siblings. Through reviews of 16 studies in the theoretical phase and interviews with 20 siblings in the field phase, the derived results were brought together in the integration phase. Results: The concept of stress in siblings of patients with childhood cancer was found to have 6 attributes and 28 indicators in 3 domains. Personal factors included 2 attributes (fear about childhood cancer and immature coping skills), and family factors had 2 attributes (changes in relationships with family and changes in family environment), social factors had 2 attributes (changes in relationships with friends and in the school experience, and insufficient social support). Conclusion: The stress of siblings of childhood cancer patients was defined as a state of tension associated with personal, family, social factors that can be related to their siblings' childhood cancer. The findings in this study provide the base for the development of a tool for measuring siblings' stress and/or the development of nursing programs for these siblings.

Information technology has economic, social and cultural impacts is closely linked to our lives. This information technology is becoming a key to the change of human civilization through connecting people and objects on the earth. In addition, future information technology is becoming more intelligent and personalized with the development of computing technology, and due to the rapid development of alcohol, environment without time and space constraint is realized, Is spreading. Since existing portable storage media are made of physical form, there is a limit to usage due to the risk of loss and limitation of capacity. Cloud services can overcome these limitations. Due to the problems of existing storage media, it is possible to overcome the limitations of storing, managing and reusing information through cloud services. Despite the large number of cloud service users, the existing research has focused mainly on the concept of cloud service and the effect of introduction on the companies. This study aims to conduct a study on individual characteristics that affect the degree of cloud use. We will conduct research on the causes of IT knowledge, personal perception of security, convenience, innovation, economical trust, and platform dependency affecting the intention to use the cloud. These results show that the variables affecting individual 's use of cloud service are influenced by individuals, and this study can be used as a basic data for individuals to use cloud service.

The Denver Developmental Screening Test was devised to provide a simple method of evaluating the developmental status of infants and preschool children. To assess the development of Korean children, 667 children (390 boys and 277 girls) between the ages of 2 weeks and 6 years who live in Kwangju city and rural areas in Chonnam were examined according to the DDST. The ages at which 25%, 50%, 75%, and 90% of the children performed each item were calculated for the entire sample. The results of these were compared with the norms of Denver children and other related previous studies in Korea. The development of the boys was also compared with that of the girls, and further the test results of city children and country children were also compared. Girls performed the DDST items in personal-social, fine motor-adaptive and gross motor sectors slightly earlier than boys. In general, however, there were no significant differences in the developmental rate between boys and girls. In all four sectors of the DDST, urban children performed the items significantly earlier than rural children. In comparing Korean children and Denver children, Korean children tended to perform gross motor and personal-social items at a slightly earlier age than Denver children. In the language sector, Denver children tended to perform a little earlier than Korean children. But on the whole there were no significant differences in developmental status between Korean and Denver children. It should be noted that a few items, such as“Uses plurals”, needed to be changed due to the structure of Korean language.

Through the rapid development in personal computer technology, it has recently become possible to make a radar become possible to make a radar simulator based on the PC. Althougth such a technology has already been developed in the advanced countries like Japan, U.K., and U.S.A., our country has not been able to make such a simulator so far. In addition, revised STCW convention requires the maritime training institution to be equipped with the ARPA simulator satisfying the performance standard specified in the convention. In this thesis therefore, an attempt was made to developed the software of the ARPA radar simulation system using Visual Basic 4.0, with which we can finally make a Mockup style ARPA simulator satisfying the performance standard specified in the convention. In this thesis therefore, and attempt was made to developed the software of the ARPA radar simulation system using Visual Basic 4.0, with which we can finally make a Mockup style ARPA radar simulator. The system developed through the research has been found to run successfully on the desk top personal computer(586PC). A Mockup style ARPA radar simulator will be able to be made by simply installing this software on the PC which will be placed inside a ARPA radar Mockup, and this is one of the future research subjects.

It was orginally thought that runaway adolescents needed to improve their ability to cope with personal problems based on their own understanding of them. As a result we exchanged theoretical background on the matter as follows: 1. Generally, adolescency is a transitional period from childhood to adulthood and characterized by a dramatic conversion period with unique phenomena relative to other periods. Futhermore, it is the key transitional moment in the development of an adult personality. 2, Runaway adolescents are defined as 'adolescents who leave impulsively or intentionally their homes without permission of their parents for at least 24 hours.' 3. The reasons for this behavior are generally regarded as complex, interdependent and dynamic including a cast-away factor. seducing factors, and other action-provoking factors. There is also another view to explain the adolescent run-away as a combination of personal. domestic, academic, peer, or socal factors. 4. We found that adolescent runaways have different attitudes dependent on the reasons and procedures of runaways, lifestyles of adolescents. and results of their runaway experience. In conclusion, runaway adolescents are in a very important period in their development and growth of bodies and minds, but are in a great crisis for various complex reasons. Therefore, we propose that nursing should provide effective nursing interventions to improve the ability of the runaway adolescents address theses problems by themselves.

Recently many administrative institutes try to improve the viability of rural villages. For increasing the viability, not only infrastructures but internal vitality is necessary in rural villages. Nonetheless, most of governmental projects have been focused on infrastructures. For this reason, RDA(Rural Development Administration) designed and performed the RHL(Rural Healthy and Longevity village) project. This RHL project is not easy to evaluate the outcome because it consists of very intangible project items. In this paper, we developed a scoring model to evaluate the result of the RHL project. The scoring model based on DEA(Data Envelopment Analysis) was suggested to evaluate the quantity of personal activities in each village. Personal activities are classified into five categories: regional life, social life, productive life, outdoor life and indoor life. Evaluating indices of each category are developed and weighting values are evaluated by AHP(Analytic Hierarchy Process). The developed model was applied to Kumsan village and examined its applicability.
