  • Objectives : The evaluation of academic achievement is pivotal for establishing accurate direction and adequate level of medical education. The purpose of this study was to firstly establish innovative item analysis technique of Item Response Theory (IRT) for analyzing multiple-choice test of herbology in the traditional Korean medicine education which has not been available for the difficulty of test theory and statistical calculation. Methods : The answers of 390 students (2012-2018) to the 14 item herbology test in college of Korean medicine were used for the item analysis. As for the multidimensional analysis of item characteristics, difficulty, discrimination, and guessing parameters along with item-total correlation and percentage of correct answer were calculated using Classical Test Theory (CTT) and IRT. Results : The validity parameters of strong and weak items were illustrated in multiple perspectives. There were 4 items with six acceptable index scores, and 5 items with only one acceptable index score. The item discrimination of IRT was found to have no significant correlation with difficulty and discrimination indices of CTT emphasizing attention of professionals of medical education as for the test credibility. Conclusion : The critical suggestions for the development, utilization and revision of test items in the e-learning and evidence-based Teaching era were made based on the results of item analysis using IRT. The current study would firstly provide foundation for upgrading the quality of Korean medicine education using test theory.

  • Purpose: This study was conducted to identify factors that influence on self-determination for withdrawal of life-sustaining treatment in the community dwelling elderly. Methods: This study used a descriptive correlational design. A convenience sample of 201 elderly were recruited from a welfare center located in Seoul, Korea. Data collection was done from September 1 to September 18, 2015. Four survey questionnaires were used: Multidimensional Scale of Perceived Social Support (MSPSS), Life Satisfaction Index-Z (LSI-Z), Attitude on Do Not Resuscitate (DNR), and Self-determination for Withdrawing Life-sustaining Treatment. Data analysis was done by t-test, ANOVA, Pearson's correlation, and hierrarchical multiple regression. Results: Hierarchial multiple regression showed that the factors predicting the level of self-determination for withdrawing life-sustaining treatment were educational level, DNR experience in family, life satisfaction, and DNR attitude. These factors explained 44% of the self-determination for withdrawing life-sustaining treatment in community dwelling elderly. Conclusion: The results of this study suggest developing educational programs aiming at changing elderly's DNR attitude positive ways so that they can enhance self-determination for withdrawing life-sustaining treatment. Further study is needed with more elderly population in extended areas.

  • Purpose: The purpose of this study was to investigate the influencing factors on Posttraumatic Growth(PTG) in patients with colorectal cancer. Methods: Eighty patients who were diagnosed with colorectal cancer at least twelve months ago were recruited from the oncology outpatient clinic of university hospital in Y city. Participants completed four survey questionnaires: Korean versions of PTG Index, Korean versions of Cancer Coping Questionnaire, Multidimensional Scale of Perceived Social Support, and a Resilience Scale. The data were analyzed by ANOVA, Pearson-correlation coefficient, and multiple regression analysis. Results: The mean score of PTG in these patients was 51.16 indicating relatively high growth. Posttraumatic Growth had significant correlations with coping, social support, and resiliency. In addition to the variables of age and education that are found to be associated with the PTG, the PTG was significantly influenced by resilience, coping, and importance of religion. Forty-nine percent of the variations in the PTG were explained by these three variables. Conclusion: The identified factors influencing colorectal cancer related to PTG could be considered in developing nursing interventions to promote positive psychological changes in response to adversity which colorectal cancer survivors might experience.

  • Background: The negative effects of gynecologic cancer on women's health is multidimensional. Sexual problems arising after chemotherapy are decreased interest and vaginal lubrication, lack of orgasm and dyspareunia and sense of reduction in sexual attractiveness in general. The purpose of this study was to evaluate changes that patients who receive chemotherapy for a gynecologic oncology disorder experience in their sexual functions. Materials and Methods: A descriptive/cross-sectional and qualitative study was performed. The Female Sexual Function Index (FSFI) was used in order to collect data on sexual capacity. The quantitative data obtained were evaluated with frequency and percentage calculations while content analysis was performed for the qualitative data. Results: All of the information related to sexuality was provided by the physician. Chemotherapy treatment affected sexuality negatively in 55.9%. Since receiving the diagnosis, 52.9% of women had experienced no sexual intercourse at all. Those who had an FSFI score of 30 and below made up 75% of the women. After the content analysis of data obtained during in in-depth interviewing, we focused on three main themes: desire for sexual intercourse, problems experienced during sexual intercourse, and coping with problems. Conclusions: An integrated system where sexual problems can be handled professionally should be present during gynecological cancer treatment.

  • Purpose: This review aimed to integrate the results of studies related to job embeddedness of clinical nurses and suggest directions for future research. Methods: A search for relevant studies was conducted using six databases according to the predetermined index terms "nurse" and "job embeddedness." A total of 28 studies that met the inclusion criteria were selected and analyzed. Results: The definition of job embeddedness was consistent in the articles, but the terms, scope, and use of tools to determine job embeddedness were not. In addition, no article suggested a theoretical framework. In all the studies except one, the tool used to measure job embeddedness was one revised from Mitchell et al. (2001). In 15 articles, a negative correlation was found between job turnover and turnover intention. Job embeddedness was also found to be associated with nurses' work environment, organizational citizenship behavior, and organizational commitment, and it had a positive impact on these variables. Conclusion: Job embeddedness can be used as a major variable to explain nurses's turnover intention. Job embeddedness is multidimensional, and a theoretical framework is needed to explain the job embeddedness of clinical nurses. Tools specific to Korea should be developed to measure the job embeddedness of Korean clinical nurses.

  • Purpose: This review aimed to integrate the results of studies related to presenteeism in clinical nurses and to suggest directions for future research. Methods: The search for relevant studies was conducted using six data bases according to predetermined index terms, "$nurs^*$" and "presenteeism." Thirteen studies that met the inclusion criteria were selected and analyzed. Results: This review found that the conceptual use and scope of presenteeism were not consistent among the studies. Most studies investigated the nurses' health-related variables as the most important factors and reported their positive association with presenteeism. Presenteeism was also found to be associated with job stress, job satisfaction, social support, and organizational culture and had a negative impact on nursing outcomes such as patient safety. Conclusion: The research on presenteeism can be used as a way to explain outcomes in the field of nursing where direct measurement of productivity is difficult. Presenteeism is a multidimensional problem, and a theoretical foundation is needed to explain the presenteeism of clinical nurses.

  • Purpose: The purpose of this study was to explore the reported good service experiences from the perspective of elderly residents of long-term care facilities. Methods: Of those residents who are 65 years old or older, 14 residents whose length of stay were one month or longer and scores of the K-Mini Mental State Examination were 15 or higher were interviewed. The interview data formed the basis for the empirical statements about the reported nature of patients' experiences as residents of long-term care facilities. These data were used in concept mapping. Results: Through multidimensional scaling analysis and hierarchical cluster analysis, 62 core statements, two dimensions, and six clusters of good service experiences were derived. The two dimensions were classified as 'care centered-participation centered services' and as 'physical-emotional services.' Six cluster themes emerged as good service experiences: 'safety of care and treatment', 'responsible and supportive staff', 'comfort of living environment', 'mental well-being', and 'respect and communication'. Conclusion: The result of the study provides information about what experiences are important to older adults with cognitive impairment. The concept map can be used to develop a patient experience index for the elderly residents of long-term care facilities.

  • Purpose: The purpose of this study was to develop an instrument to assess nursing professional pride. Methods: Fifty-six preliminary items were identified through literature review and focus group interview of nurses working in a hospital. Of these, 45 preliminary instruments were completed over 0.80 of content validity index. To verify the reliability and validity of the preliminary instrument, data were collected from 294 nurses. The data were analyzed using factor analysis and multidimensional scaling analysis. Results: From the factor analysis, 27 significant items were divided into 5 subscales. These subscales were as follows: feeling of vocation, role satisfaction, role of problem solver, self-achievement, and willingness to stay. The nursing professional pride also established criterion-related validity, discriminant validity, and group validity. Cronbach's α of the instrument was .92, and the subscales ranged from .74 to .85. Conclusion: The developed scale for nursing professional pride shows validity and reliability. The significance of this study is the development of an instrument capable of measuring nursing professional pride. To verify the relevance of this instrument, conducting comparative studies is suggested.

  • With the continuous development of LBS (Location Based Service) applications, privacy protection has become an urgent problem to be solved. Differential privacy technology is based on strict mathematical theory that provides strong privacy guarantees where it supposes that the attacker has the worst-case background knowledge and that knowledge has been applied to different research directions such as data query, release, and mining. The difficulty of this research is how to ensure data availability while protecting privacy. Spatial multidimensional data are usually released by partitioning the domain into disjointed subsets, then generating a hierarchical index. The traditional data-dependent partition methods need to allocate a part of the privacy budgets for the partitioning process and split the budget among all the steps, which is inefficient. To address such issues, a novel two-step partition algorithm is proposed. First, we partition the original dataset into fixed grids, inject noise and synthesize a dataset according to the noisy count. Second, we perform IH-Tree (Improved H-Tree) partition on the synthetic dataset and use the resulting partition keys to split the original dataset. The algorithm can save the privacy budget allocated to the partitioning process and obtain a more accurate release. The algorithm has been tested on three real-world datasets and compares the accuracy with the state-of-the-art algorithms. The experimental results show that the relative errors of the range query are considerably reduced, especially on the large scale dataset.

  • The study identifies gender stereotypes, examines the level of women's economic empowerment at the household level and explores the influence of factors on it. Data were collected from 159 randomly selected farm women using both qualitative and quantitative survey methods between January and March 2007 from three villages of the Mymensingh District of Bangladesh. Four key informants (2 local leaders and 2 development personnel) were questioned to elicit views in the light of boosting women's empowerment. Five constructs of empowerment covering 30 indicators were aggregated together to develop a cumulative economic empowerment index (CEEI) to obtain multidimensional views of women's empowerment. The findings show that there were some prejudices against women in allocating divisions of labour and access to education, food, property, decision-making and institutions. The distribution of the CEEI demonstrates that the majority of the respondents (86%) had a low to moderate level of empowerment. A multiple regression analysis showed positive significant effects of education, training, media contact and freedom of mobility on women's CEEI, while domestic abuse restrained it. It is concluded that interventions by development agencies in co-ordination with the local community was necessary to attain women's self-reliance in the study area. Development actors can undertake some core strategies to enhance women's level of awarencess, knowledge, skills, and productive resources through providing training, loans, and information. To change traditional beliefs, it is important to create awareness of various gender issues amongst rural people through different methods and media.
