  • 자기주도적 학습에서는 학습자가 학습과정을 구성할 수 있다. 그러나 학습자가 방대한 학습 콘텐츠의 특성을 이해하고 학습과정을 구성하기는 매우 어렵다. 본 연구에서는 학습자가 학습을 계획할 때 학습자의 학습 선호도를 산출하여 학습자에게 맞는 학습 콘텐츠 유형 정보를 학습자에게 제공하는 방법을 제시하였다. 학습 선호도 산출방식은 토픽 맵의 선호도 벡터값을 이용하였다. 제안방법의 적용을 위해 학습 모집단 20명을 대상으로 테스트 하였으며, 전체적인 학습 만족도가 높게 나타남으로서 제안방법이 학습자의 학습구성에 도움이 되고 있음을 제시하였다.

  • Background: In Iran, breast cancer is the most prevalent cancer in women and a major public health problem. Methods: A cross sectional study was carried out to determine knowledge on breast cancer and breast self-examination (BSE) practices of 384 females living in the city of Hamadan, Iran. A purposive sampling method was adopted and data were collected via face-to-face interviews based on a validated questionnaire developed for this study. Results: Among respondents 268 (69.8%) were married and 144 (37.5%) of the respondents reported having a family history of breast cancer. One hundred respondents (26.0%) claimed they practiced BSE. Level of breast cancer knowledge was significantly associated with BSE practice (p=0.000). There was no association with demographic details (p<0.05). Conclusion: The findings showed that Iranian women's knowledge regarding breast cancer and the practice of BSE is inadequate. Targeted education should be implemented to improve early detection of breast cancer.

  • 본 논문에서는 여유 자유도를 이용한 두 팔 로봇 매니퓰레이터의 충돌 회피 알고리즘을 제안한다. 여유 자유도를 갖는 각 로봇 팔의 엔드-이펙터는 서로의 충돌을 회피하면서 주어진 작업을 수행하기 위하여 각각 미리 정의된 직선 경로를 따라 이동해야 한다. 이 문제를 풀기 위해서 엔드-이펙터의 위치와 방향을 변화시키지 않는 각 축의 동작인 자체동작을 이용한다. 매 샘플링 시간마다 각 팔의 링크들이 서로 멀어지는 방향으로 자체 동작을 수행함으로써 엔드-이펙터가 주어진 작업도 성공적으로 수행하고, 동시에 서로의 충돌도 회피할 수 있다. 제안한 알고리즘의 성능을 분석하기 위하여 각각 9자유도의 팔을 갖는 두 팔 로봇 매니퓰레이터에 대한 모의실험을 수행하고 그 결과를 제시한다.

  • Purpose: This study was to predict the stage of exercise behavior change in undergraduate students and to identify the factors affecting exercise behavior change by using the trans theoretical Model. Method: The subjects were 193 undergraduate students at K and D university in D city. Data were collected by questionnaire surveys using convenience sampling and analyzed by SPSS 12.0 program. Results: 77.7% of 193 nursing students do not exercise or they exercise irregularly. Exercise self-efficacy score and exercise benefits score were decreased with advancing exercise stage, on the other hand exercise barriers score and the process of exercise behavior change score were increased. In addition to this, the results revealed that stage of exercise behavior was significantly correlated with the process of exercise behavior change, exercise benefits, exercise barriers and exercise self-efficacy. Conclusion: These results suggested that the process of exercise behavior change, exercise decisional balance and exercise self-efficacy can be potential affecting factors for the stages of behavior change in university students. Therefore, these findings give useful information for educating nurse to construct nursing service programs focused on the stage of behavior change.

  • This study aims to investigate relationships between benefit sought and selection attributes of green tea consumers. For data collection, a total of 595 copies of questionnaires were collected by convenience sampling in the Seoul and Gyeonggi-do area. The data were analyzed by using SPSS 15.0. The factor analysis identified four dimensions of the benefit sought : health benefit, sensory, sociality, and self-esteem. Six dimensions of selection attributes were identified as manufacturing, design, sensory appeal, recommendation, utility and brand. The results of the canonical correlation analysis indicated that health benefit, sensory, sociality of benefit sought and manufacturing, design, sensory appeal, recommendation, utility, brand of selection attributes were highly correlated, and the self-esteem of benefit sought and recommendation of selection attribute were highly correlated. This means it is important to place an emphasis on safety production, package design, sensory characteristics, product description, utility and brand for consumers who seek health benefit, flavor and sociality. It is also important to place an emphasis on product description for consumers who pursue self-esteem benefits. Green tea marketers should consider benefit sought aspects as the most important factors affecting selection attributes on green tea purchasing.

  • Purpose: Recently as couples have only one or two children, they concern about their children's optimal health. Furthermore, as the basic principles of Korean traditional prenatal education (Taegyo) are supported by scientific evidence, and as increasing numbers of pregnant women are recognizing Taegyo refresh, the practice of Taegyo is growing. The purpose of this study was to identify the factors associated with the practice of Taegyo among pregnant Korean women. Methods: This was a cross-sectional, survey study of 228 pregnant women recruited at a health center in South Korea using a convenience sampling method. The instruments included the perception of Taegyo scale, the spouse's support scale, the self-confidence for infant care scale, and the practice of Taegyo scale. The data were analyzed using descriptive statistics and multiple regression analyses. Results: The results of the stepwise multiple regression analysis indicated that the following factors accounted for 26.5% of the variance in the practice of Taegyo: the perception of Taegyo, family income. Conclusion: Consequently, this result showed that the pregnant women were influenced by family income, spouses' support as requisite factors, and also they developed the level of self-confidence for infant care and the perception of Taegyo as self-care agency for the practice of Taegyo. The present study findings will add to the accumulated knowledge of health care professionals about the cultural factors involved in the practice of Taegyo and the traditional cultural beliefs and culture-specific health promoting behaviors of ethnic minority pregnant women to provide culturally competent care for them.

  • Purpose: This study aimed to identify related factors of prenatal depression by stress-vulnerability and stress-coping models for pregnant women. Methods: A cross-sectional survey design with a convenience sampling was used. A total of 107 pregnant women who visited a general hospital in a metropolitan city were recruited from August to October, 2013. A structured questionnaire included the Korean version of Beck Depression Inventory II, and the instruments measuring Self-Esteem, Marital Satisfaction, Pregnancy Stress, Stressful Life Events, and Coping. The data were analyzed using descriptive statistics, t-test, Parson's correlation analysis, and stepwise multiple regression. Results: The mean score of prenatal depression was $11.95{\pm}6.2$, then showing 19.6% with mild depression, 15.0% with moderate depression, and 0.9% with severe depression on BDI II scale. Prenatal depression had positive correlation with pregnancy stress (r=.55, p<.01), stressful life events (r=.26, p<.01) and negative correlation with self- esteem (r=-.38, p<.01), marital satisfaction (r=-.40, p<.01), and coping (r=-.21, p<.05). Factors of pregnancy stress, self-esteem, stressful life events, and planned pregnancy explained 38% of the total variance of prenatal depression. Conclusion: These findings show that health providers need to assess prenatal depression and to control the influencing factors.

  • Purpose: This study determines the effect of spending distribution, namely experiential, impulsive, self-expressive, prosocial, and conspicuous spending, on the financial well-being of young working women in Malaysia. Research design, data and methodology: This study employed a quantitative and deductive approach. A sample of 400 young working women was selected using a systematic sampling technique. Data were collected using a self-administered questionnaire and analysed using Structural Equation Modelling (CB-SEM). Results: The findings revealed prosocial and impulsive spending as the significant spending distribution to affect financial well-being. The effect of prosocial spending is positive on financial well-being, while the effect of impulsive spending is a negative predictor of financial well-being. All other spending distribution - experiential, self-expressive, and conspicuous spending - do not have a significant effect on financial well-being. Conclusion: To achieve financial well-being, young working women need to distribute the spending budget for the happiness of others and reduce impulse buying. The findings provide useful insights on the significant role of spending distribution in influencing, how to fuel young working women to develop good spending habits that consequently improve their financial well-being, for themselves and Malaysian economics, as well as the plausible solution to overcome financial problems and high indebtedness.
