As the more web contents are available through the internet, relative importance of electronic resources in the library collection has gradually increased. While several measurement criteria are used for the effective collection development, the usage statistics is generally accepted as the key factor to assess the retention and cancellation of electronic resources. In this paper it was examined the roles and problems inherent in the electronic journals usage statistics, and then the quality of electronic journal usage reporting services provided by several publishers were evaluated, following the ICOLC and COUNTER guidelines. To apply the usage statistics of electronic journal on the library collection development, it is necessary that libraries, related association and publishers accomplish more consistent and practical usage statistics components. And it is recommended that publisher and aggregator accommodate the guideline for electronic journal usage report.

Patents are an up-to-date and reliable source of technological knowledge, and thus patent analysis has been considered to be a necessary step for identifying evolving technological trends and planning technology strategies. Although there exist many research papers and technical reports concerning patent analysis, few empirical studies on planning technology strategies for uncertain futures from a national or company perspective have been rarely conducted. Therefore, this paper aims presenting a procedure and its practical case of planning future technology strategies by incorporating patent analysis and scenario planning. Using patents related to polymer electrolyte membrane fuel cells, this paper developed technology strategies corresponding to future scenarios. We expect that the proposed method and case study can assist knowledge services of experts in the long-term technology strategy planning process.

The purpose of this study is to establish more rational and practical planning theory for amusementpark. It analyze and considerate the fluctuation of the people who come and use a Tong-Ch'on amusementpark. The results drawn from this research work are as follows ; There are considerable correlation between use fluctuation and some factors. The factors are season (spring, summer, autumn) as a time, temperature, cloud amount, duration of sunshine, weather (rainy day) as a climate and date (weekday, holiday) as a social system. The important variables are temperature, cloud amount, duration of sunshine and date (week day, holiday) to estimate the user of amusementpark. I can reduce the following two types of regression models. 1.${\log}_eY1=6.9114+0.1135TEM+0.00002_eSUM-0.4068WI+0.4316W3$ ($R^2=0.94$) 2. ${\log}_eY2=7.2069+0.1177TEM-0.0990CLO+0.488W3$ ($R^2=0.95$) Y ; Number of User TEM ; Temperature CLO ; Amount of cloud SUN ; Duration of Sunshine WI ; Weekday W3 ; Holiday Those model is inorder to estimate the user for management of Tong-Ch'on amusementpark and use on the computation of facility size for reconstruction. Besides the amusementpark, city park and outdoor recreation area could estimate of user throuth this method. But, I am not sure about the regression models because I didn't apply the regression models to the other amusementpark, city park or outdoor recreation area. Therefore, I think that this problem needs to study in the future.

Successful project planning relies on a good estimation of the effort required to complete a project, together with the schedule options that may be available. Despite the extensive research done developing new and better models, existing software effort estimation models are present only the total effort and instantaneous effort function for the software life-cycle. Also, Putnam presents constant effort rate in each phase. However, the size of total effort are variable according to the software projects under the influence of its size, complexity and operational environment. As a result, the allocated effort in each phase also differ from project to project. This paper suggests the criteria for effort allocation in planning, specifying, building, testing and implementing phase followed by the project total effort. These criteria are derived from 183 different projects. This result can be considered as a practical guideline in management of project schedule and effort allocation.

Data multicasting from a source to multiple sinks in wireless sensor networks is used to achieve both reducing communication costs and energy efficiency. Almost all existing schemes for the multicasting might be effectively performed by optimal construction of a multicasting tree between a source and multiple stationary sinks. However, in practical sensor applications, sinks could move around on the wireless sensor networks for own missions, such as scouting of soldiers and saving lives of victims by firefighters. Unfortunately, the sink mobility causes frequent entire reconstruction of the multicasting tree and thus it leads to exhaustion of battery power of sensors. Hence, we propose an energy-efficient multicast protocol to support multiple mobile sinks by the local multicast tree reconstruction, called Local Update-based geographic Multicasting for Mobile sinks (LUMM) for wireless sensor networks. Our simulation results show that our scheme for mobile sinks is more efficient in terms of energy resource management than other exist works.

Purpose: This study aims to determine obstetrics nurses knowledge, attitude, and practice about breast cancer and breast self-examination (BSE), and to contribute to the early detection of breast cancer during breastfeeding periods. Methods: For the survey, 163 individuals (obstetric nurses) were chosen by convenience sampling and agreed to participate in the study. Their knowledge, attitude, and practice about breast cancer and BSE. Results: Knowledge and attitude averaged $70.45{\pm}10.90$ (of 100) and $3.64{\pm}0.27$ (of 5), respectively. While most nurses (99%) recognized the importance of BSE, only 58.9% experienced BSE. BSE practice level averaged $8.35{\pm}1.96$ (of 12). Only 20.2% had recommended BSE to their clients. Practice level varied significantly for different marital status, breastfeeding experience, and education, while knowledge and attitude remained independent. Nurses who had experienced mammogram or breast ultrasonogram themselves scored higher in knowledge. Attitude was higher for nurses who received recommendation for BSE, performed BSE, received BSE education, or recommended BSE to clients. Practice level was higher for nurses who received BSE education or willing to perform BSE in future. Practice level had a positive correlation with attitude but no correlation to knowledge. Conclusion: Obstetric nurses need continuing education for practicing BSE. Practical BSE education can not only promote preventive behavior of nurses, but it can also improve the breast health management of obstetrical clients.

Purpose: Postpartum fatigue can impact maternal well-being and has been associated with levels of perceived self-care. This study aimed to examine the relationship among fatigue, depressive mood, self-care agency, and self-care action among postpartum women in Bangladesh. Methods: A descriptive cross sectional survey was done with 124 first-time mothers from two tertiary hospitals in Dhaka, Bangladesh. The Modified Fatigue Symptoms checklist, Denyes' Self Care Instrument, the Edinburgh Postnatal Depression Scale, and items on sociodemographic and delivery-related characteristics, were used in Bengali via translation and back-translation process. Results: High fatigue levels were found in 18.5% (n=23) and 73.4% had possible depression (n=91). There was a significant negative relationship between fatigue and self-care agency (r=-.31, p<.001), and self-care action (r=-.21, p<.05). Fatigue differed by level of self-care agency (t=4.06, p<.001), self-care action (t=2.36, p=.023), newborn's APGAR score (t=-2.93, p=.004), parental preparation class participation (F=15.53, p<.001), and postpartum depressive mood (t=-4.64, p<.001). Conclusion: Findings suggest that high level of self-care efficacy and behaviors can contribute to fatigue management, and highlight the need for practical interventions to better prepare mothers for postpartum self-care, which may, in turn, alleviate postpartum fatigue.

This study aimed to explore and understand the meaning and essence of their experiences in the context of Vietnamese daughter-in-law and rural elderly women's lives. Van Manen's hermeneutics phenomenological method was used. Participants of the study were 8 people who live with a Vietnamese Daughter-in-law. Data was collected through individual in-depth interviews. 8 essential themes and 28 themes were derived from the data analysis. The rural elderly women who had Vietnamese Daughter-in-law had to continuously provide support for their son's family and were subject to a high level of stress due to the differences between Korean culture and Vietnamese culture. The findings can be used to develop a practical and comprehensive community nursing intervention based on the perspectives of all family members. For further study, exploratory study on the grandson who has a Vietnamese mother or the son who has a Vietnamese wife is recommanded.
