Purpose: The objective of this study was to examine the affected period and the amount of bone formation during osteogenesis of intramembranous bone using low-intensity pulsed ultrasound (LPUS) $in$ $vivo$. Methods: Xeno-bone (Bio-oss) and autogenous bone were grafted bilaterally into mini-pig mandibles. The left mandible served as the control and the other mandible was treated with 3 MHz, 160 mW (output, 0.8 mW) ultrasound stimulation for 7 days 15 minutes per day. The mini-pigs were sacrificed at 1, 2, 4, and 8 weeks, and micro computed tomography (${\mu}CT$), a microscopic examination, and a statistical analysis were performed on the specimens. Results: Based on a computerized image analysis of the ${\mu}CT$ scans, the experimental group had an average 150% more new bone formation than that in the control group. The effect of LPUS continued during the post operative 2 weeks. The histomorphological microscopic examination showed similar results. Conclusion: Our results suggest the LPUS had an effect on early intramembranous bone formation in vivo.

Barley sprouts contain various secondary metabolites such as polyphenol, policosanol, and γ-aminobutyricacid (GABA). In particular, saponarin, which accounts for about 72% of polyphenols, is well known for anti oxidant, anti-inflammatory, and liver function protection effects. Saponarin is greatly affected by environmentalconditions such as light, temperature, and moisture. However, there is a lack of studies about the effect of themicroclimatic environment on saponarin content in barley sprouts. This study was conducted to evaluate theinfluence of daily temperature range, light intensity, and light period on saponarin, water-soluble vitamins, andminerals content in barley sprouts. Seeds of Hordeum vulgare L. were sown on a plastic box and cultivated ingrowth chambers with different conditions by adjusting daily temperature range (DT, 0 → 10°C), light intensity(LI, 120 → 180 µmol m-2 s-1), and light period (LP, day 12 hours → day 18 hours). The plants were harvestedwhen the leaf length reach 15 cm. The fresh weight was not significantly different between each treatment, yetthe growth period was highest in barley sprouts cultivated with DT. Saponarin content was higher in DT, LIand LP than control, and highest saponarin content in DT. In contrast, vitamin C content was highest in controland lowest in DT. Similarly, vitamin B1 and B5 content showed the highest in control. Changes in light andtemperature elevated saponarin content in barley sprouts, especially daily temperature range showed adramatic increase. However, the change in daily temperature range affects an increase in growth period and adecrease in vitamin C content. In conclusion, daily temperature range is the predominant environmental factorto produce saponarin-enriched barley sprouts.

A variety of organic materials has been currently used for the nutrient management in agricultural land. However, there is little study to understand the impact of organic materials for crop production with soil bio-chemical properties. The aim of this research was to investigate the effect of organic materials using pepper crop (Capsicum annuum). Using oil-cake and amino acid fertilizer as organic materials, both soil characteristics such as bio-chemical properties and microbial community and pepper yield were tested for three years. The pepper was cultivated with four different treatments; Control (No fertilizer), NPK (inorganic fertilizer), OCF (Oil-cake), and (OCF+AAF) (Oil-cake with amino acid fertilizer). The result of soil properties showed that available phosphate content and microbial biomass were the highest in NPK and organic matter content was higher in OCF and OCF+AAF than NPK. Biochemical properties including activities of β -glucosidase, acid phosphatase, alkaline phosphatase and arylsulfatase were not different among all treated samples. For pepper yield, OCF and OCF+AAF showed 10 - 40% less than NPK. Therefore, this study concludes that organic materials affect microbial biomass linked with organic matter contents and alter the soil microbial community.

Connecting irony and humor with witticism and lightheartedness

윤영은 경희대학교 언어정보연구소 2014 언어연구 Vol.31 No.1

Irony and humor have long been studied as two closely related phenomena by numerous researchers. Some, including Hänninen (1989) and Dews et al. (1995), have argued that humor derives from irony, while others, including Hay (2001), have regarded irony as a variety of humor. Recently, Hirsch (2008; 2011a, b) proposes a comparative model that differentiates irony from humor in the literary texts by means of some cues for irony and humor. Reyes et al. (2012) also propose a set of features that represent humor and irony. In this context, the purpose of this paper is to reexamine the relationship between irony and humor, and to provide an answer to the long-lasting question of why these two phenomena appear to be closely related. In order to answer this question, the works of an anonymous feminist artist group, the Guerrilla Girls, from 1985 to 2013, which are effectively utilizing both irony and humor, will be analyzed. It will be observed that uncommon wordings and phrasings in a witty and clever way involved in the irony examples induce humor, and that the situation where any seriousness or intensity is relieved works as a precondition for generating humor from the irony examples. Based on these observations, it will be proposed that the ‘witticism’ involved in most irony examples derives humor, and that the so-called ‘lightheartedness’ also plays a role in generating humor. It will further be proposed that GG’s works clearly show that ‘witticism’ and ‘lightheartedness’ are two essential components of most effective ironic utterances.

영어와 한국어의 비유정성 주어 타동사 구문 재고

It is generally observed that transitive constructions with inanimate subjects are not usually preferred either in English or Korean. However, Korean exhibits a much stronger nonpreference for those constructions than English. To account for this difference between English and Korean, Kim et al.(2009) resort to ‘animacy,’ whereas Jang(2009) employs ‘agentivity.’ However, since these concepts, ‘animacy’ and ‘agentivity,’ serve as primary factors in determining the subject of a transitive construction both in English and Korean, neither Kim et al.’s or Jang’s analysis effectively explains the strong tendency of avoiding inanimate subjects in Korean transitive constructions. In this context, we analyze both literary and nonliterary English-Korean translation data and discuss the strategies to avoid inanimate subjects in transitive sentences observed in the data. We attempt to account for this avoidance in terms of the difference in the ‘subject hierarchies’ of English and Korean. (Ewha Womans University)

Epidermolysis bullosa (EB) represents a spectrum of conditions that are characterized by blistering and mechanical fragility of the skin. There is genetic heterogeneity and marked variation in clinical phenotypes in the multiple EB disorders. The most recent classification recognizes four major EB grouping and over 30 EB subtypes. The severity of EB ranges from mild to severe skin involvement, and it can be localized or generalized. Oral features include repeated occurrence of blisters, erosions, and scars, which lead to limited mouth opening, ankyloglossia, elimination of buccal vestibule, and increased risk of oral carcinoma. Routine dental care or even normal tooth brushing might cause bullae on the oral mucosa. Occasionally, the clinician will be called upon to treat patients with EB and should therefore be aware of specific treatment modifications. we present a reviews of the literature with a case providing adequate anesthetic and surgical care.

Purpose: Recent studies have reported the association between metabolic syndrome and benign prostatic hyperplasia. This study was conducted to evaluate the relation between metabolic syndrome and prostate-specific antigen (PSA). Materials and Methods: From January 2004 to December 2007, a total of 4,115 male outpatients (aged 40 to 79 years) who visited the health care center at our medical center were examined. Eligible men were classified according to the presence or absence of metabolic syndrome and the number of components of the metabolic syndrome. The association between the sum of metabolic syndrome components and PSA level was evaluated. The association between each metabolic syndrome component and PSA level was also evaluated. Results: The PSA level of metabolic syndrome patients was lower than that of the control group (p=0.022). An increased number of metabolic syndrome components was significantly associated with a linear, decreasing trend in PSA levels (p-trend=0.040). When a Pearson's correlation was performed, only obesity was inversely associated with PSA level in the metabolic syndrome group. There was no significant factor that was related to having a PSA level greater than or equal to 2.5 ng/ml. Conclusions: Metabolic syndrome should be considered as a factor associated with reduced PSA levels. If the patient with metabolic syndrome is obese, the PSA cutoff value should be lower than 4 ng/ml.

Building Equipment field is getting important recently which satisfies the requirement for pleasant living environment. But, the noise generated in the machinery room often violates the pleasant living environment of residents in complicated form of airborne noise and soild sound, its seriousness is increasing so that damage of noise can take large percentage of environmental complaints. So, soundproofing and insulation of sound which can minimize such noise and effective countermeasure in case of civil appeal are required, but research materials regarding building equipment are definitely insufficient domestically. In this respect, this study used Zwicker parameter which is applied by psychological and acoustic reactions according to sound quality, analyzed sound quality of 32 kinds of building equipment used in machine room, and analyzed correlation between dB(A) and PSIL which are items of Zwicker parameter and noise valuation based on that. As the results, if valuates altogether loudness and unbiased annoyance which have high correlation with other existing suggested valuating methods, it is considered that it can be utilized as basic data for more reasonable and accurate grasping characteristics of noise from building equipment and for building effective countermeasure in case of civil appeal.

Purpose: We performed this study to investigate the predictive factors that are related to recovery from acute urinary retention after non-urogenital surgery. Materials and Methods: We retrospectively analyzed the records of 160 patients who were referred to the department of urology because of lasting acute urinary retention after non-urogenital surgery at our institution between January 2004 and December 2006. Patients were divided into two groups: a transient retention group, which included patients who recovered voiding capability after urinary catheterization for 7 days, and the unresponsive retention group, which included patients who did not recover voiding capability. Surgical factors, patient factors, use of patient- controlled analgesia (PCA), amount of residual urine, and medications during catheterization were analyzed. Results: In the chi-square analysis, gender (female, p=0.006), age (≥60 years old, p<0.001), preoperative voiding difficulty (p=0.028), comorbidity with hypertension (p=0.001), diabetes mellitus (p=0.003), location of surgery (pelvic cavity, p=0.005), amount of intraoperative fluid (≥4,000 ml, p=0.002), and intraoperative indwelling of Foley catheter (p=0.026) were found to differ significantly between the two groups. In the multivariate logistic regression analysis, gender (female, p=0.002; OR=5.6), age (≥60 years old, p=0.001; OR=5.9), hypertension (p=0.049; OR=2.6), location of surgery (pelvic cavity, p<0.001; OR=20.125), and amount of intraoperative fluid (≥4,000 ml, p=0.001; OR=8.5) were found to increase the risk of unresponsive urinary retention. The residual urine volume of the unresponsive urinary retention group was larger than that of the transient urinary retention group (741±306 ml vs. 614±222 ml, p=0.003). Conclusions: Use of a preoperative indwelling catheter and careful management of urination is necessary to prevent unresponsive urinary retention in patients with risk factors such as female gender, old age, hypertension, surgery in the pelvic cavity, and a large amount of intraoperative fluid injection.
