  • Purpose: The purpose of this study was to examine the effects of light therapy on sleep disturbance and depression in climacteric women with menopausal symptoms. Methods: The research design was a nonequivalent control group pre test-post test design. Data were collected from September 29, 2013 to November 11, 2013. Participants included 17 climacteric women in an artificial light therapy group, 17 climacteric women in a sun light therapy group and 16 climacteric women in a control group. Measures consisted of the sleep disturbance, depression, melatonin, and serotonin. Results: There was a statistically significant difference of Korean Sleep Scale A (F=53.87, p<.001), and melatonin (F=31.19, p<.001) among three groups. There was a statistically significant difference of Self-Rating Depression Scale (F=121.86, p<.001), and serotonin (F=102.37, p<.001) among three groups. Conclusion: Artificial and sun light therapy can be applied as a supportive nursing intervention to subjects with sleep disturbance and depression in climacteric women with menopausal symptoms. Artificial and sun light therapy is expected to be a complementary alternative intervention for health management of the subjects with sleep disturbance and depression in climacteric women with menopausal symptoms.

  • This paper has two primary objectives: (1) to propose a comprehensive theoretical model that incorporates valuable insights from two complementary streams of research, and (2) to empirically test the model that explain the task-media fit and satisfaction of customer contact center users. The comprehensive model was tested using LISREL analysis on the sample of 232 users who have experience with the customer contact center. The model was supported in customer contact center context, accounting for 29% of the variance in the task-media fit, 53% of the variance in the perceived ease of use, 61% of the variance in the perceived usefulness, and 52% of the variance in the user satisfaction. The results showed that the task-media fit, the perceived ease of use, and the perceived usefulness play a significant role in influencing the user satisfaction of the customer contact center. In addition, task analyzability, media richness, media interactivity, and self-efficacy were found to influence the task-media fit. The paper concludes with discussions and implications for researchers and practitioners.

  • This study investigated an effective countermeasure of each restaurant under the present market conditions by grasping consumers‘ brand recognition and preferences over six restaurants in the metropolitan area centering around Seoul and comparing and analyzing selection properties that satisfy customers. The survey used a self-recording method that respondents write in the answers in person, and its subjects were the customers of restaurants in the metropolitan area from July to August, 2006. We made the MDS(multidimensional scaling) analysis of the available data from 408 respondents, using the SPSS statistical analysis program. The result was as follows. First, there were intensely competitive relationships between Nolboo Bossam and Wonhalmeoni Bossam, and between Outback Steakhouse and TGIF. Marche and Bennigan’s, however, didn‘t have a competitive relationship but kept a complementary one. Second, Wonhalmeoni Bossam was most favorably commented upon in its facilities, atmosphere, location, services, convenience(business hours, parking, transportation), recognition(popularity, fame, advertisement), sanitation and cleanliness, reasonable prices (food and drinks), etc., and then came Nolboo Bossam, TGIF, Outback Steakhouse, Bennigan’s, and Marche in that order. Third, in case of selection properties on taste of food, TGIF was estimated as the best, and then came Outback Steakhouse, Bennigan's, Marche, Wonhalmeoni Bossam, and Nolboo Bossam.

  • Furnace slag powder used currently in Korea needs to add special functions in response to the increase of large-scale projects. In addition, it is advantageous in that it has a lower hydration heat emission rate than ordinary Portland cement and improves properties such as the inhibition of alkali aggregate reaction, watertightness, salt proofness, seawater resistance and chemical resistance. However, furnace slag powder is not self -hardening, and requires activators such as alkali for hydration. Accordingly, if recycled fine aggregate, from which calcium hydroxide is generated, and furnace slag, which requires alkali stimulation, are used together they play mutually complementary roles, so we expect to use the mixture as a resource-recycling construction material. Thus the present study purposed to examine the properties and characteristics of furnace slag powder and recycled aggregate, to manufacture recycled fine aggregate concrete using furnace slag and analyze its performance based on the results of an experiment, to provide materials on concrete using furnace slag as a cement additive and recycled fine aggregate as a substitute of aggregate, and ultimately to provide basic materials on the manufacturing of resource-recycled construction materials using binder and fine aggregate as recycled resources.

  • Fifty-three isolates of Fusarium graminearum were obtained from corn and barley samples in several provinces of Korea. Gas chromatography-mass spectrometric analysis of trichothecenes produced by these isolates revealed that 37 and 16 isolates were nivalenol (NIV)- and deoxynivalenol (DON)-chemotypes, respectively. Two hundred and seventy-five nitrate-nonutilizing (nit) mutants were obtained from the isolates. Of these mutants, 187 were identified as nit1, nit3, or NitM, but 88 could not be identified as one of these classes. The highest frequency of nit mutant was nit1 (65%), followed by nit3 (20%) and NitM (15%). Higher frequency of NitM was observed in DON-chemotypes than in NIV-chemotypes. The mutants were used for vegetative compatibility group (VCG) analysis by examining heterokaryosis using complementary mutant pairs. No heterokaryon formation was observed among all 1,248 pairwise combinations, suggesting that all isolates tested belong to different VCGs. Higher frequency of self-incompatibility was observed in NIV-chemotypes than in DON-chemotypes. These results suggest that the like-lihood of asexual genetic recombination may be very low I F. graminearum under the field condition.

  • During the screening of material which has the antimicrobial activity against aminoglycoside-resistant bacteria, A new material ${\varepsilon}-(L-{\beta}-lysine)$ polypeptide from a culture medium of Streptomyces sp.(DWGS2) was isolated, and the structure and the physicochemical properties of the new material were elucidated. The new material was separated by column chromatography of the culture medium using Dowex $1{\times}2$, Silica gel, and Sephadex LH20 etc. The structure and molecular weight were determined with the data of NMR, MALDI mass, and ESI mass experiments. And the monomer obtained by hydrolysis of the new material with 6N-HCI was identified as a $L-{\beta}-lysine(T_2)$, which is a tail of bleomycin. As tail-region analogy, $T_2({\beta}-lysine$ derivatives from streptomyces) interactions with a self-complementary oligonucleotides, $d(CGCTTCGAAGCG)_2$, was investigated by NMR.

  • This paper describes trends in conventional scaling compared with advanced technologies such as 3D integration (3DI) and bumpless through-silicon via (TSV) processes, as well as the characteristics of CMOS (Complementary Metal Oxide Semiconductor) Logic device after thinning the wafers to less than $10{\mu}m$. Each module process including thinning, stacking, and TSV, is optimized for 3D Wafer-on-Wafer (WOW) application. Optimization results are discussed with valuable data in detail. Since vertical wiring of bumpless TSV can be connected directly to the upper and lower substrates by self-alignment, bumps are not necessary when TSV interconnects are used.

  • Purpose: This study aimed to examine the effect of auricular acupressure therapy on reducing the ocular symptoms and signs for dry eye syndrome. Methods: The participants who were aged ≥ 40 years old and met the inclusion criteria of the ocular surface disease index score ≥ 13 and a tear film break-up time ≤ 10 seconds were enrolled into the two groups: experimental group (n=29) and control group (n=27). Experimental group received auricular acupressure therapy for 8 weeks. Seed stickers were applied to the eye, liver and tubercle point of each ear once a week. Data were collected at pre and 4 and 8 weeks after the treatment and analysed the efficacy of intervention by repeated measures ANOVA. Results: There were significant differences in the ocular surface disease index, standard patient evaluation of eye dryness and a tear film break-up time in both eyes at 8 weeks after the treatment between the two groups. Conclusion: The findings indicate that the auricular acupressure therapy may be helpful for relieving symptoms of dry eye as a nursing intervention. In addition, it could also be utilized as a self-care practice using proper education and training.

  • The complementary DNA (cDNA) of potato virus Y- vein necrosis strain (PVY-VN) replicase gene (Nlb) was transformed into tobacco (Nicotiana tabacum cv. Burley 21) plants. Out of 25 putative transformants regenerated, 3 were resistant to PVY-VN, one highly resistant plant with no symptom until seed harvest time and the other two with mild chlorotic spot symptoms at late stages after infection. No symptom was observed in the highly resistant plant, while mild vein necrotic symptoms were developed on suckers of the moderately resistant plants after seed harvest time, In the first generation (T1) via self fertilization, resistance to susceptibility frequency in transgenic plants from the highly resistant transformant was about 3 : 1, while it was lowered much (about 1:2 and 1:19) in T1 of the moderately resistant transformants. In the second generation (T2) of the highly resistant plant, resistance frequencies were similar to T1, but resistance levels varied greatly and appeared to be decreased. Key words : potato virus Y, viral replicate gene, transgenic tobacco plants, resistance.
