The purpose of this study is to explore and describe the health and welfare needs experienced by old parents living with disabled adult children, and to help generate research interest and public policy attention on this critical issue. For the purpose of this study, the survey was conducted with older parents who are living with dependent adult children with physical or mental disability. Among collected data for this study, data for 105 older parents were analyzed. The results showed that older parents have suffered with care responsibilities for their disabled adult children as well as special needs resulted from their old age. And older parents have little or even nothing prepared for later life because of lifetime economic, physical and social difficulties related to their disabled children. Also these difficulties had a significant impact on their idea of health and welfare needs in later life. It showed that older parents had mainly concerned and wanted to have the direct cash benefits and medical provisions but hardly recognised the importance of other services such as leisure activities. Preliminary suggestions of this study therefore may be helpful to improve the public policy approach in order to better serve older parents with disabled adult children in the coming aging society.

This paper proposes an integrated management system for products of game software development. Those products generated over software life-cycle are generally huge in numbers, various in kinds and interconnected in relationships among them. Especially they are highly complex and tightly coupled each other because they are used to build another world which is composed of multi-modal data such as graphics, sound, logics and so on. Therefore it is critical to manage development products in an integrated manner to guarantee the quality of software. The proposed system is designed to provide project/requirement/configuration/traceability management capabilities and interfacing to CASE standards. To achieve the objective, it is based on data warehouse technologies which provide central repositories of heterogeneous data, multi-aspect reporting&analysis capabilities, traceability, verification, etc.

Cyclooxygenase (COX)-2 is generally known as an inducible enzyme, and it produces arachidonic acid to prostaglandin $E_2$ ($PGE_2$), which has been demonstrated to play a critical role in inflammation. In the present study, we investigated the effects of the extracts of fermented beans including soybean (FS), black agabean (FBA) and yellow agabean (FYA), on the expression of COXs and production of $PGE_2$ in U937 human promonocytic cells. Treatment of phorbol 12-myristate 13-acetate (PMA) significantly induced pro-inflammatory mediators such as COX-2 expression and $PGE_2$ production, whereas the levels of COX-1 remained unchanged. However, pre-treatment with FS, FBA and FYA significantly decreased PMA-induced COX-2 protein as well as mRNA, which is associated with inhibition of $PGE_2$ production. Moreover, FS, FBA and FYA markedly prevented the increase of nuclear translocation of nuclear factor kappa B (NF-${\kappa}B$) p65 by PMA. Our data indicate that the extracts of fermented beans exhibits anti-inflammatory properties by suppressing the transcription of pro-inflammatory cytokine genes through the NF-${\kappa}B$ signaling pathway.

The purpose of this study is to pave the way to promote the institutional commitment of the students enrolled by identifying the factors that affects on their institutional commitment. The data collection was conducted starting from November 19, 2020 until November 26, 2020 by using online questionnaires and 220 participants were from C-university students in Chang-won, Kyung-nam Province. As a result of analysis, the average score for institutional commitment was 3.30, the average level of satisfaction of university life was 3.62, the cultural climate was 3.39 and the level of satisfaction for extracurricular program was 3.48, which was in high range. Institutional commitment has a positive correlation between the level of satisfaction of university life, the level of satisfaction for extracurricular programs(p<.001). The most critical factor that affects the institutional commitment was the level of satisfaction of university life and the level of satisfaction for extracurricular programs, the cultural climate in order. The result can be interpreted that institutional commitment is influenced by students' major and the level of satisfaction of university life and the level of satisfaction for extracurricular programs, and the level of satisfaction of university life has relatively high level of influence out of other factors, indicating that the effort to improve the institutional commitment of the students is needed at the collegiate level.

Background : Recently, two commercialized whole-blood assays, $QuantiFERON^{(R)}-TB$ Gold (QFT) and T $SPOT-TB^{(R)}$ (SPOT), which measure the $IFN-{\gamma}$ released in the whole blood after being incubation with mycobacterial antigens, were approved for the diagnosis of a latent tuberculosis infection (LTBI). However, there is data on whether or not the previously used PPD skin tests (TST) have any influence on the diagnostic ability of these ex-vivo $IFN-{\gamma}$ assays. Methods : Forty-six 15 year-old students who did not appear to be infected with Mycobacterium tuberculosis were enrolled in this study. The peripheral blood was collected and used for two $IFN-{\gamma}$ assays. The $IFN-{\gamma}$ assays and TST were performed at the baseline ($1^{st}$). The TST was repeated two months later ($2^{nd}$), and the $IFN-{\gamma}$ assays were repeated two ($2^{nd}$) and four months ($3^{rd}$) later only in those subjects who had negative results at the baseline in both the $IFN-{\gamma}$ assays and TST. An induration size > 10 mm was considered to be positive in the TST. Results : The mean TST value was $3.1{\pm}5.4mm$ (range: 0-20). Of the 46 subjects examined, 13 subjects (28.3%) showed positive results in the two-step TST. Nine (19.6%) were SPOT-positive and only one (2.2%) was QFT-positive. The $2^{nd}$ and $3^{rd}$ QFT were carried out in 23 and 25 all-negative subjects, respectively, and all showed negative results. The $2^{nd}$ SPOT was performed in 23 subjects and only one (4.3%) showed a weak-positive result. Conclusion : Even though there were some discrepancies in the results of the two ex-vivo $IFN-{\gamma}$ assays, it appears that their results were not influenced by a previous TST carried out in two or four months earlier.

The study was intended to identify the nurses' experiences, understanding, and attitudes on DNR. Also, the study was to provide the data base for a standard of DNR decision-making and practice. The sample consisted of 347 nurses in eight general hospitals. The data were collected between August 1 and August 31, 2000. The data were analyzed using descriptive statistics and $x^2-test$. The results of the study were as follows : 1. Regarding DNR-related experience, 74.6 percent of the participants experienced DNR situations. Eleven percent of the participants received DNR education. DNR was most frequently (81.5%) requested by family members and relatives of patients. The decision-making on DNR was most frequently (76.8%) made by agreement between family members and medical staff. The DNR order was recorded at 81.9 percent on charts. Problems after DNR order were negligence in treatment and nursing care (30.6%) and guilty feelings due to doing the best (22.1%). CPR (cardiopulmonary resuscitation) was performed about 49.8 percent of DNR cases. 2. Regarding understanding and attitude on DNR, most of the participants (93.1%) thought DNR was necessary. The major reasons for the necessity of DNR were impossible recovery (44.4%) and death with dignity (41.1%). The decision-making on DNR was most frequently made by patient and family members (47.8%) and followed by agreement between family members and medical staff (25.6%), and patients themselves (16.4%). Most of the participants thought that medical staff must explain DNR to critical and end-of-life patients and their family members. Forty four percent of the participants thought that the most appropriate time for DNR explanation was when patients with critical disease were admitted to hospitals. Most of the participants (90.2%) thought a guide book for DNR is necessary to be made in hospitals. 3. There were significant differences in the participants' understanding and attitudes on DNR according to religion career education and experience of DNR. Of the participants those who have religions and education experience on DNR thought that there would be more DNR requests after DNR is explained to patients and family members (p<.05). In addition, there was higher understanding on the necessity of DNR in those who have more career and DNR experience(p<.01). The findings of the study suggest that a guide book for DNR need to be made with inclusion of legal, ethical, and cultural aspects. Also, there needs to be more education on DNR in medical ethics to health care professional and to provide more information on DNR to the general public.

This paper presents a unique study of Structural Health Monitoring (SHM) for the maintenance decision making about a real life movable bridge. The mechanical components of movable bridges are maintained on a scheduled basis. However, it is desired to have a condition-based maintenance by taking advantage of SHM. The main objective is to track the operation of a gearbox and a rack-pinion/open gear assembly, which are critical parts of bascule type movable bridges. Maintenance needs that may lead to major damage to these components needs to be identified and diagnosed timely since an early detection of faults may help avoid unexpected bridge closures or costly repairs. The fault prediction of the gearbox and rack-pinion/open gear is carried out using two types of Artificial Neural Networks (ANNs): 1) Multi-Layer Perceptron Neural Networks (MLP-NNs) and 2) Fuzzy Neural Networks (FNNs). Monitoring data is collected during regular opening and closing of the bridge as well as during artificially induced reversible damage conditions. Several statistical parameters are extracted from the time-domain vibration signals as characteristic features to be fed to the ANNs for constructing the MLP-NNs and FNNs independently. The required training and testing sets are obtained by processing the acceleration data for both damaged and undamaged condition of the aforementioned mechanical components. The performances of the developed ANNs are first evaluated using unseen test sets. Second, the selected networks are used for long-term condition evaluation of the rack-pinion/open gear of the movable bridge. It is shown that the vibration monitoring data with selected statistical parameters and particular network architectures give successful results to predict the undamaged and damaged condition of the bridge. It is also observed that the MLP-NNs performed better than the FNNs in the presented case. The successful results indicate that ANNs are promising tools for maintenance monitoring of movable bridge components and it is also shown that the ANN results can be employed in simple approach for day-to-day operation and maintenance of movable bridges.

Oral history research is carried out through collecting information about a living person. The data collected from an oral history project is not a mere fact or a mass of information but accounts of persons who reveal their own personalities. For this reason, oral history research and data collection and the use of such data must be based on rigorous ethical standards. The Bioethics and Safety Law shares a similar view on human subject research, and the Institutional Review Boards includes human subject research as a subject of review and management. However, the Bioethics and Safety Law's protection of personalities and human rights focuses on life sciences methodologies, which are not suitable for qualitative research, such as an oral history of a value oriented and critical approach to human beings. This study examines the details of the Bioethics and Safety Law related to human subject research and the problems that may arise when this law is applied to subjects in humanities and social sciences such as oral history. Through this study, alternative methodologies, which can be used for oral history research, while maintaining academic autonomy, are suggested.

Purpose: This study aims to provide primary data for policy alternatives by identifying the problem of the nursing workforce shortage. Methods: For quantitative data, 446 questionnaires were analyzed. The mean and standard deviation were used for content description. ANOVA analysis and Scheffe? test were used to compare the differences according to the hospital level. For qualitative data, 1:1 in-depth and group interviews were conducted for six participants. Results: The factors nurses prioritized when choosing a workplace were salary, commuting distance, and work-life balance. Clinical nurses cited low wages, heavy workloads, and burnout as the most considerable difficulties in performing their duties. Factors influencing nurse's turnover intention were low wages, unmanageable workload, and rotation to unwanted departments in that order. New nurses tend not to apply to small-medium-sized hospitals, experienced nurses in their 30s-40s leave hospitals due to childcare and shift work difficulties, and nurses in their 50s and older tend to move to nursing homes rather than acute hospital settings. Conclusion: In this study, wage and workload were mentioned as the most critical factors in nurses' workplace selection, job performance difficulties, and turnover intention, so it is necessary to pay attention to this aspect when improving treatment for nurses.

This review focuses on the nutritional effects from birth until age at first calving on growth, mammary developmental changes, and first-lactation milk yield in heifer calves. The advancement in the genetic potential and the nutritional requirements of the animals has hastened the growth rate. Genetic selection for high milk yield has suggested higher growth capacity and hence increasing nutritional inputs are required. Rapid rearing by feeding high energy or high concentrate diets not only reduces the age of sexual maturity but also lowers the time period of attaining the age of first calving. However, high energy diets may cause undesirable fat deposition thereby affecting future milk yield potential. Discrepancies exist whether overfed or overweight heifers at puberty can influence the mammary development and future milk yield potential and performance. The data on post-pubertal nutritional management suggested that body weight at calving and post-pubertal growth rate is important in first lactation milk yield. There is a continuous research need for strategic feeding that accelerates growth of dairy heifers without reduction in subsequent production. Nutritional management from birth, across puberty and during pregnancy is critical for mammary growth and for producing a successful cow. This review will mostly highlight studies carried out on dairy breeds and possible available opportunities to manipulate nutritional status from birth until age at first calving.
