This study was conducted to compare the unmet needs and quality of life of permanent and temporary ostomates. The research subjects were 128 ostomates with colorectal cancer or other advanced cancers. Data were collected by self-reported completion of the Comprehensive Needs Assessment Tool in Cancer (CNAT) and the City of Hope Quality of Life (COH-QOL) Ostomy Questionnaire from February 1 to April 5, 2018. Collected data were analyzed by chi-squared and independent t-tests using IBM SPSS 21.0. The results showed that the unmet need for temporary ostomates was significantly higher than that of permanent ostomates (t=-2.284, P=0.024). Moreover, temporary ostomates showed a higher unmet need for information and education (t=-2.747, p=0.007), psychological problems (t=-2.578, p=0.011), and physicians (t=-2.599, p=0.010). Although quality of life of temporary ostomates seems lower than that of permanent ostomates, there was no significant difference between groups (t=-1.364, P=0.0175). Therefore, it is necessary to develop a self-management program to provide appropriate information and psychological support for temporary ostomates.

Objective : The purpose of study is to validate the clinical utility and usability of the Korean version of the Life Space Assessment(K-LSA) which is an assessment tool of community mobility of older adults. Methods : Surveys on the clinical utility and usability of the K-LSA are carried out with a total of aoaa60 occupational and physical therapists. The surveys included the multiple choice questions on the clinical utility and open questions on the usability. Responses to multiple questions are post processed by frequency analysis and technical statistics, and responses to the open questions are categorized by common factors in each questions. Results : Average value of clinical utility ranges from 3.6 to 4.0 with positive responses of 'fair (3 point)', 'agree (4 point)' and 'strongly agree (5 point)' being 95~100%. Average value for clinical usability ranges from 3.6 to 4 with positive answers of 'fair (3 point)', 'easy (4 point)' and 'very easy (5 point)' being 88.3~100%. Additionally out of open-type questions of clinical usability, it was pointed out that the concept of 'neighborhood' for the life space level 3 and 4 is unclear. Conclusion : The current study and research outcomes showed that the K-LSA is a validated tool in Korean health care system for the clinical utility and usability in measuring community mobility, and that it is straightforward in practical use. It will help clinicians and therapists promote the social participation of older adults, and set an intervention goal for enhancing community mobility. It will further help clinicians and researchers in education and research for medical intervention and goal-setting.

The silkworm performs sexual reproduction for the production of its healthy offsprings from generations to generations. Parthenogenesis in the silkworm, Bombyx mori acquires immense use in the development of outstanding homozygouse lines with higher viability, hybrid vigour, combining ability and less phenotypic variability, and it can serve as a powerful tool in controlling sex of the offsprings as well as a useful tool in selection of breeding schemes. However, naturally occuring parthenogenesis in silkworm could not be found so far. Fortunately, artificial induction of parthenogenesis is possible in silkworm. So, it is very important to find out novel methods for induction of parthenogenesis. We investigated to attempt to get a novel parthenogenetic method. Accordingly, parthenogenetic studies on between unfertilized in vivo ovarian eggs of live silkworm moth(novel) and unfertilized in vitro ovarian eggs(conventional) taken out from live silkworm moth were investigated by hot water ($46^{\circ}C$), hot air ($46^{\circ}C$) and low temperature ($0^{\circ}C$ and $-20^{\circ}C$) treatments. The best ratio of parthenogenetic eggs was obtained with in vivo ovarian eggs of live silkworm moth rather than with in vitro ovarian eggs taken out from live silkworm moth in all the treatments. The optimum exposure time absolutely depended upon the temperatures of treatments and the forms of in vivo or in vitro ovarian eggs. From these results, we expect that in vivo artificial parthenogenetic treatments on live silkworm moth will be useful for the higher induction of parthenogenesis in the silkworm, B. mori.

These days sex has become a tool of interest, a constant stream of sex crimes occurs and it brings the age of population cliffs to an age of low birth rates. As an alternative to overcome these problems, we should establish the praying for a child, which has been our ancestors' way of life, as a sacred culture that holds the mystery of life-birth with a new awareness. Therefore, the purpose of this study is not to re-enact the Zhaungam area as a fun and interesting place, but as a sacred place to pray for the nobility, longevity and wealth of life. Based on the spirit of natural love, meeting, healing, and love based on the spirit of traditional culture, Doridori was chosen as the main theme of the project based on the spirit of natural love and life-respect, and the name "Doridori Secret Garden" was given out of 10 medals in Dandong for tourism storytelling. Cultural content becomes a marketing tool for the region and acts as a force for tourists to visit the area. In this context, it was confirmed that the creation of "Doridori Secret Garden" could lead to a high value-added industry that attracts tourists by enhancing the brand value of Andong and showing sufficient significance to become a new attraction. This study is intended to re-create the Zhaungam area as a sacred place to pray for the nobility of life and longevity and wealth of life, noting that people still pray for the birth of their children in Zhaungam and Zhagungam.

A life-cycle assessment (LCA) is based on the attention given to the environmental protection and concerning the possible impact while producing, making, and consuming products. It includes all environmental concerns and the potential impact of a product's life cycle from raw material procurement, manufacturing, usage, and disposal (that is, from cradle to grave). This study assesses the environmental impact of the ultra pure water process of semiconductor manufacturing by a life-cycle assessment in order to point out the heavy environmental impact process for industry when attempting a balanced point between production and environmental protection. The main purpose of this research is studying the development and application of this technology by setting the ultra pure water of semiconductor manufacturing as a target. We evaluate the environmental impact of the Precoat filter process and the Cation/Anion (C/A) filter process of an ultra pure water manufacturing process. The difference is filter material used produces different water quality and waste material, and has a significant, different environmental influence. Finally, we calculate the cost by engineering economics so as to analyze deeply the minimized environmental impact and suitable process that can be accepted by industry. The structure of this study is mainly combined with a life-cycle assessment by implementing analysis software, using SimaPro as a tool. We clearly understand the environmental impact of ultra pure water of semiconductor used and provide a promotion alternative to the heavy environmental impact items by calculating the environmental impact during a life cycle. At the same time, we specify the cost of reducing the environmental impact by a life-cycle cost analysis.

An attempt was made to link rice embryo proteins to DNA sequences and to understand their functions. One hundred of the 700 spots detected on the embryo 2-DE gels were microsequenced. Of these, 28% of the embryo proteins were matched to DNA sequences with known functions, but 72% of the proteins were unknown in functions as previously reported (Woo et al. 2002). In addition, twenty-four protein spots with 100% of homology and nine with over 80% were matched to ESTs (expressed sequence tags) after expanding the amino acid sequences of the protein spots by Database searches using the available rice EST databases at the NCBI (http://www/ncbi.nlm.nih.gov/) and DDBJ (http://www.ddbj.nig.ac.jp/). The chromosomal location of some proteins were also obtained from the rice genetic map provided by Japanese Rice Genome Research Program (http://rgp.dna.affrc.go.jp). The DNA sequence databases including EST have been reported for rice (Oryza sativa L.) now provides whole or partial gene sequence, and recent advances in protein characterization allow the linking proteins to DNA sequences in the functional analysis. This work shows that proteome analysis could be a useful tool strategy to link sequence information and to functional genomics.

Purpose: The purpose of this study is to present basic data that can be used as a program to improve emotional stability and daily life ability by reducing depression and improving the quality of life of the elderly using day care facilities. Research design, data and methodology: Changes in each stage of the study subjects were observed and interviewed, and pre- and post-tests were conducted on the depression and quality of life of the elderly in the group program. The measurement tool was designed for pre-and post-test using the tools of the Korean Elderly Depression Test (K-GDS) and the elderly's quality of life test. Results: As a result of observing and interviewing participants, and examining attitudes and reactions to each session, the pre-test showed a negative attitude, but then communicated with each other to form a positive relationship. As a result of pre- and post-test on the depression and quality of life of the elderly in the group art program, it was found that depression decreased and quality of life improved after participating in the program. Conclusions: This study was conducted by dividing the physically and psychologically deteriorated elderly into a control group and an experimental group. Sharing stories from past experiences had a positive effect on relationships with group members, and the elderly who have difficulty expressing their inner feelings through art, a non-verbal medium, had a positive effect on their satisfaction with their quality of life as they felt a sense of achievement after seeing the work.

The meta-analysis has become a widely used tool for many applications in bioinformatics, including genome-wide association studies. A commonly used approach for meta-analysis is the fixed effects model approach, for which there are two popular methods: the inverse variance-weighted average method and weighted sum of z-scores method. Although previous studies have shown that the two methods perform similarly, their characteristics and their relationship have not been thoroughly investigated. In this paper, we investigate the optimal characteristics of the two methods and show the connection between the two methods. We demonstrate that the each method is optimized for a unique goal, which gives us insight into the optimal weights for the weighted sum of z-scores method. We examine the connection between the two methods both analytically and empirically and show that their resulting statistics become equivalent under certain assumptions. Finally, we apply both methods to the Wellcome Trust Case Control Consortium data and demonstrate that the two methods can give distinct results in certain study designs.

The genetic diversity and phylogenetic relationships of eleven herbaceous peonies grown in Korea were analyzed by random amplified polymorphic DNA (RAPD). Twenty-four decamer RAPD primers were used in a comparative analysis of these Korean peony species. Of the 142 total RAPD fragments amplified, 124 (87.3%) were found to be polymorphic. The remaining 18 fragments were found to be monomorphic (12.7%) shared by individuals of all 11 peony species. Cluster analysis based on the presence or absence of bands was performed by Jaccard's similarity coefficient, based on Unweighted Pair Group Method with Arithmetic Averages. Genetic similarity range was 0.39 to 0.90 with a mean of 0.64. This study offered a rapid and reliable method for the estimation of variability among different peony species which could be utilized by the breeders for further improvement of the local peony species. Also, the results propose that the RAPD marker technique is a useful tool for evaluation of genetic diversity and relationship amongst different peony species.
