The Bubble sort graph is node symmetric, and can be used in the data sorting algorithm. In this research we propose and analyze that Half Bubble sort graph that improved the network cost of Bubble sort graph. The Half Bubble sort graph's number of node is n!, and its degree is ${\lfloor}n/2{\rfloor}+1$. The Half Bubble sort graph's degree is $${\sim_=}0.5$$ times of the Bubble sort, and diameter is $${\sim_=}0.9$$ times of the Bubble sort. The network cost of the Bubble sort graph is $${\sim_=}0.5n^3$$, and the network cost of the half Bubble sort graph is $${\sim_=}0.2n^3$$. We have proved that half bubble sort graph is a sub graph of the bubble sort graph. In addition, we proposed a routing algorithm and analyzed the diameter. Finally, network cost is compared with the bubble sort graph.

"Journal of Korean Academy of Adult Nursing" has been published since 1989 and more than 330 articles have been published up 2000. We reviewed all the articles published in this journal to analyze the contents and trend of published articles and to find out the way of improvement both in quantity and quality of studies in this area. The results are as follows : 1) Ninety percent of articles were quantitative studies. Experimental design was used in 16.1% and quasi-experimental design was adapted in 73.6% of articles. Qualitative research were 10.3% of total articles reviewed. 2) Only 5.1% of articles described theoretical framework and 73.6% of experimentally designed articles included research hypotheses. 3) Among experimental studies, only one was true experimental studie design. Eighty nine point three persent had descriptive survey method among non-experimental studies. Amog the thirty four qualitative studies, phenomenologic(73.5%), grounded theory(14.7%), and ethnographic (11.8%) design were used. 4) Most of research subject were patients and few healthy people, healthcare worker, and patient family. 5) Psychosocial data collection method which used questionnaire were 53.7% and interview. physical measurement, observation were used in 22.8%. 8.2% 5.4% of articles respectively. 6) Total number of keywords were 692, and average number of key words per article was 2.2. Health-related keyword was the most frequently used according to four metaparadigm of nursing (human, health, nursing, and environment). Environment related keyword was rarely appeared. The number and quality of nursing research in "Journal of Korean Academy of Adult Nursing" have been improved continuously. It is difficult to find out special trend or characteristics which is unique in this journal because of relatively short history of adult nursing studies. This review study was performed to analyze adult nursing studies only in the view of quantitative aspect, but it is needed to analyse qualitatively to find philosophical or theoretical trend in nursing.

Purpose: Purposes of this study were to understand the current trends on complementary therapy in relieving chemotherapy-induced nausea and vomiting and to suggest the future research direction. Method: Subjects were selected on CINAHL, MEDLINE, Korean Academy Data Base from 1980 to 2001 which used nausea, vomiting, chemotherapy and complementary therapy as key words in experimental studies. Eight korean articles and twenty-one international articles were analyzed in terms of general characteristics, research methods, and types of complementary therapy. Data were analyzed by using descriptive statistical methods. Result: Since 2000, researchers have more actively used complementary therapy. In subject characteristics, mean age was 35.5 years old, 45% of the researchers were performed with high level of incidence of chemotherapy induced vomiting, 14% of them set limit of consecutive cycle during research, and 65% of them did not comment the selecting criteria of sample. About 60% of them were designed post-test only control group: 35% used INV by Rhodes, 31% used Likert scale, and 24% used VAS for dependent variable. Muscle relaxation therapy was mostly applied for relief of nausea and vomiting. Conclusion: Further studies will be needed to control extrinsic variables affecting nausea and vomiting in research design and to accumulate evidence with studies applying various complementary therapies.

Anti-inflammatory and antioxidant effects of umbelliferone in chronic alcohol-fed rats

Sim, Mi-Ok,Lee, Hae-In,Ham, Ju Ri,Seo, Kwon-Il,Kim, Myung-Joo,Lee, Mi-Kyung The Korean Nutrition Society 2015 Nutrition Research and Practice Vol.9 No.4

BACKGROUND/OBJECTIVES: Inflammation is associated with various types of acute and chronic alcohol liver diseases. In this study, we examined whether umbelliferone (7-hydroxycoumarin, UF) ameliorates chronic alcohol-induced liver damage by modulating inflammatory response and the antioxidant system. METHODS: Rats were fed a Liber-Decarli liquid diet containing 5% alcohol with or without UF (0.05 g/L) for 8 weeks, while normal rats received an isocaloric carbohydrate liquid diet. RESULTS: Chronic alcohol intake significantly increased serum tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin 6 levels and decreased interleukin 10 level; however, UF supplementation reversed the cytokines related to liver damage. UF significantly suppressed hepatic lipopolysaccharide binding protein, toll-like receptor 4 (TLR4), nuclear factor kappa B, and TNF-${\alpha}$ gene expression increases in response to chronic alcohol intake. Masson's trichrome staining revealed that UF improved mild hepatic fibrosis caused by alcohol, and UF also significantly increased the mRNA expressions and activities of superoxide dismutase and catalase in liver, and thus, decreased lipid peroxide and mitochondrial hydrogen peroxide levels. CONCLUSIONS: The findings of this study indicate that UF protects against alcohol-induced liver damage by inhibiting the TLR4 signaling pathway and activating the antioxidant system.

Sim, In Ok,Bae, Ok Yeon,Kim, Tae Hoon Korean Academy of Child Health Nursing 2021 Child Health Nursing Research Vol.27 No.1

Purpose: While clinical practice is crucial for nursing students to acquire the skills needed to provide professional, high-quality nursing care, further studies on improving undergraduate nursing programs are needed to provide a supportive clinical learning environment for student nurses. This study aimed to understand nursing students' clinical experiences in newborn nurseries and neonatal intensive care units and to provide basic data for the establishment of strategies to promote effective clinical education. Methods: Interviews were held with 15 nursing students at J University who had clinical practice experience in the newborn nursery and neonatal intensive care unit. The collected data were analyzed using the phenomenological analysis method developed by Colaizzi (1978). Results: The nursing students' experiences were grouped into four categories: "expectations for and anxiety about clinical practice", "acquisition of a wide range of knowledge regarding neonatal nursing", "challenges faced in clinical practice", and "experiencing interpersonal changes". Conclusion: The current neonatal practice nursing education system provides students with positive learning experiences. However, the lack of practice opportunities, insufficient instruction, and the theory-practice gap were identified as major issues hindering students' learning needs. These study results are expected to provide basic data for curriculum development to improve undergraduate nursing education.

본 연구는 서울시 소재 데이케어센터를 이용하는 노인을 대상으로 이들의 삶의질 개선과 복지수를 높일 수 있도록 인지력과 감각력을 융합하는 미술프로그램을개발ㆍ적용한 후 그 효과성을 검증한 것이다. 본 연구의 미술 활동은 데이케어센터를이용하는 노인들이 대부분 장기요양 등급판정 기준에 따라 등급을 판정받은 노인이지만, 이들을 병리적 치료의 목적이 아닌 유년시절을 기억하고, 생활에서 흥미를느낄 수 있도록 구안한 것이다. 더불어 기억력을 회생시키고 양손 활용을 통해 좌, 우뇌 발달을 도모할 수도 있다. 미술프로그램은 실생활 중심과 순수미술 중심의미술 활동인데 실시한 결과 사회복지사, 노인참여자, 수업진행 교사들 모두 만족도높았다. 특히 노인참여자들의 만족도는 상당했다. 다만 이러한 미술활동이 많은데이케어센터의 주요 활동이 되길 기대한다. The present study aimed at verifying the effects after developing and applying an art program which fuses perceptivity and sensibility in order to develop the quality of life and to boost the happiness index with the subjects of the senior citizens who use senior citizens’ day and night care centers located in the city of Seoul. The art activities of the present study were designed not for their pathological treatment, but for letting the elderly to remember their childhood and feel interests in their daily life, although most of them have senile dementia. Moreover, it can revive their memory and the development of both left and right side of brain can be planned through the use of both hands. The art program has real life- oriented and pure art-oriented activities. The results of the activities showed that the social workers, the elderly participants, and the teachers who proceeded the classes were highly satisfied. Especially, it was revealed that the satisfaction of the elderly participants were quite significant. It is expected that this kind of art program would become the major activities of many senior citizens’ day and night care centers.

The study aims to restore Korean traditional pattern-weaving technology and gold thread-manufacturing technology that were cut off. For this research, the blue Jik-geum Neung with mandarin ducks which was found in the National Treasure No. 1572 Gilt-Bronze Amitabha inside Buddhist Statue Enshrinement in Munsusa Temple in 1346 was selected as a subject relic. Because it has proved that manufacturing gold threads and weaving with supplementary gold wefts that were done in Korea in the past. The characteristics of its textile, patterns, weaving and gold threads are analyzed by microscope and examine the naked eye. Based on these analytical data of the subject relics, Korean traditional gold threads are reconstructed under professional technique. Also, warp thread, end thread, patterns and weaving are reproduced based on these data. In addition, a Korean traditional draw loom with a dual structure (top and bottom) is reproduced to restore weaving Korean traditional gold wefts that have the same characteristics of the subject. This study is expected to be used in various ways such as representation and restoration of Korean traditional gold-in-woven textile and costume, and modern crafts. For succession of tradition and utilization of the restored weaving techniques, transmission education of the technology is needed to inherit and develop cultural traditions.
