As a first step for improvement of breeding and productivity of Epimedii Herba, the patterns of components and the difference in icariin, a main component of this plant, in compliance with seasons and places of collection were evaluated by HPLC. As a result, the patterns of components in samples collected in July-September were shown to be markedly increased compared to those collected in May. Corresponding to the alternations of the pattern, the amount of icariin, which was estimated to be 0.017% in May was found to be increased markedly up to 0.82% in September. The samples collected at Chul-won district showed the highest icariin contents (0.94%), however, those collected in China was only 50% level (0.4%) of domestic ones. These results strongly suggest that the quality of Epimedii Herba might be quite different with respect to the seasons and places of the collection.

Background: The objective of the present study was to examine the status of patients who had received dental treatment under intravenous (IV) sedation at Chungnam Dental Clinic for the Disabled in Korea from its inception to the present time, and to review the analysis results. Methods: Retrospective analysis was performed on 305 cases of patients who had received dental treatments under IV sedation between January 2011 and May 2016. The analysis examined the patient's sex, age, primary reason for IV sedation, duration of anesthesia and dental treatment, type of dental treatment performed, number of clinical departments involved in the dental treatment and level of multidisciplinary cooperation, and annual trends. Results: Most dental treatments using intravenous sedation were performed on medically disabled patients or dentally disabled patients with an extreme gag reflex or dental phobia. The mean duration of IV sedation was 72.5 min, while the mean duration of treatment was 58.0 min. The types of dental treatments included surgical treatment (n = 209), periodontal treatment (n = 28), prosthodontic treatment (n = 28), restorative treatment (n = 23), implant surgery (n = 22), endodontic treatment (n = 9), reduction of temporomandibular joint dislocation (n = 1), and treatment of traumatic injuries (n = 1), with treatments mostly performed on adult patients. Conclusions: With increasing demand for minimally painful treatment, cases using IV sedation are on an upward trend and are expected to continue to increase.

Purpose: This study is performed to measure the level of nursing and medical service satisfaction according to consumer's demographic and hospital using behavior characteristics, and investigate the relationship among the nursing service satisfaction and the medical service satisfaction and the hospital revisiting intent. Method: The questionnaire is distributed to 300 patients at the six general hospitals in provincial city, Korea. For data analysis, SPSS/PC program is used. Result: The characteristics of consumer's demographics and hospitals using behavior that make difference in nursing and medical service satisfaction are education, the average number of the visiting(by month) and hospitals. Nursing service satisfaction correlated with medical service satisfaction(r=.677) and hospital revisiting intent(r=.570), and medical service satisfaction correlated with hospital revisiting intent(r=.680). Nursing service satisfaction explained medical service satisfaction(45.9%) and hospital revisiting intent(32.5%), and medical service satisfaction explained hospital revisiting intent(54%). Conclusion: It is concluded that education, the average number of the visiting(by month) and hospitals make difference in nursing and medical service satisfaction, and there are very close relationship among nursing service satisfaction and medical service satisfaction and hospital revisiting intent. Nursing service is a very important factor to improve medical service satisfaction and hospital revisiting intent.

This study aims to reveal the capacity of impacts that the diffusion of networked computer in rural areas, or so-called rural telematics, has on regional development schemes. It is accomplished mainly by a case study of a small rural village near the city of Weonju, Korea, which has been recently designated as an information model village by the provincial government and given supports for information infrastructure. The case study shows that although the residents'computer use is confined to a very elementary level in every respect of using internet, e-mails, and visiting village portal site, there is high potential that extended use of networked computer would bring positive changes in life-styles and community formulation, and hence new possibilities of regional development. These positive moves will be possible by increasing economic, social and cultural benefits that the residents receive from using computer facilities. One of the important prerequisites is to transform external motivation to internal one and to lead the residents to a more active use of computers.

Wind measurements were made on the Canton Tower at a height of 461 m above ground during the Typhoon Vincente, the wind-induced accelerations and displacements of the tower were recorded as well. Comparisons of measured wind parameters at upper level of atmospheric boundary layer with those adopted in wind tunnel testing were presented. The measured turbulence intensity can be smaller than the design value, indicating that the wind tunnel testing may underestimate the crosswind structural responses for certain lock-in velocity range of vortex shedding. Analyses of peak factors and power spectral density for acceleration response shows that the crosswind responses are a combination of gust-induced buffeting and vortex-induced vibrations in the certain range of wind directions. The identified modal frequencies and mode shapes from acceleration data are found to be in good agreement with existing experimental results and the prediction from the finite element model. The damping ratios increase with amplitude of vibration or equivalently wind velocity which may be attributed to aerodynamic damping. In addition, the natural frequencies determined from the measured displacement are very close to those determined from the acceleration data for the first two modes. Finally, the relation between displacement responses and wind speed/direction was investigated.

Two types of diets, extruded pellet (EP) and raw-fish-based moist pellet (MP) were fed to compare growth, water quality and histology of olive flounder, Paralichthys olivaceus in Jeju fish farm. Two groups of 7000 fish per each tank (initial mean weight 51 g) were fed one of two diets for 7 months. At the end of the feeding trial, significant differences were found in weight gain and feed utilization. Dissolved oxygen (DO) level of the MP tank was decreased from 7.98 to 6.89 after feeding. There were no significant differences in hematocrit, hemoglobin, alanine aminotransferase and aspartate aminotransferase of fish fed the two diets. Whole body protein content of fish fed the EP was significantly higher than that of fish fed the MP. While the feeding rate by month indicated numerically decreased, fish fed the MP had higher feed intake than that of fish fed the EP. Histological examination of hepatopancreas, kidney, and anterior intestine of fish fed the EP did not show any negative effects compared to those of fish fed the MP. This study revealed that EP could substitute for MP in terms of growth performance, blood parameters, water quality and histology of olive flounder.

The purpose of this study was to examine the effects of alcohol use, depression, and self-esteem on suicidal ideation of older adults. Community-dwelling older adults aged 65 years and older were recruited from three welfare centers. A total of 245 older adults was assessed with the Alcohol Use Disorder Identification Test-Korean (AUDIT-K), Geriatric Depression Scale Short Form-Korea Version (GDSSF-K), Self-Esteem Scale (SES), and Scale for Suicidal Ideation (SSI). Descriptive statistics, Pearson's correlation, independent t-test, one-way ANOVA, and multiple regression analysis were performed using the SPSS WIN 19.0 program. Higher depression, lower self-esteem, no religion, and poorly perceived health were statistically significant determinants of higher level of suicidal ideation in older adults. To prevent or reduce suicidal ideation of older adults, health care providers should consider the determinants identified in this study.

This study aimed to examine the coping, self-disclosure, rumination, organizational culture and degree of Posttraumatic Growth(PTG) of firefighters who experienced trauma, and to identify the factors that influence PTG. Data collection was conducted for 103 firefighters working at three fire departments located in Gyeongsang-do. As a result of the study, 46(44.7%) PTGs of medium to high level averaged 58.07 points, and the total PTG average was 44.56 points. The influenced factors affecting PTG in firefighters were emotional-focused coping(EFC), self-disclosure(SD), deliberate rumination(DR) and innovative-oriented culture(IOC).The explanatory power of these factors PTG was 45.9%. In order to promote the firefighters 'PTG, it is necessary to approach of EFC, SE, and DR but also an organizational aspect as well as IOC construction, and these results can be used as an arbitration plan to improve the firefighters' PTG.

According to Formalist theory, form is not separate from content. Form does not merely convey or express content but can itself produce meaning. The close correlation of the narrative structure, more specifically the time structure of the narrative, and the narrative style of Kim Seung-Ok′s short story′"Travel in Mujin" provides a good example of this argument. The story opens with the first-person narrator, currently living in the bustling city of Seoul, back in his small provincial home town Mujin, where he brings up memories that had been hitherto suppressed. The revived memories are ordered into the narrator′s present thought structure, in effect bridging the vast psychological rift between the lost past and the present. The narrator′s travel in Mujin thus becomes a psychological journey, and Mujin becomes a psychological space where the narrator can experience the continuity of his own being. The "narrating I" excludes the principles of reality from his narrative, concentrating on the inner thoughts, recollections, psychological experience, and the level of consciousness of the "narrated I." This narrative attitude or style expresses the narrator-protagonist′s acceptance and affirmation of the thoughts and actions occur in Mujin (which he had till now been resistant to). It is also an affirmation of the narrative act itself. Before the travel back to Mujin, the narrator-protagonist′s thoughts about his home town was ambivalent-an attitude originating from nostalgia, together with the narrator-protagonist′s ambivalent attitude toward his youthful past. It is a reflection of the narrator-protagonist′s desire for purity intermingled with a disdain for his enervated existence in Seoul. This ambivalence is resolved by the "I" of the narrative present, and Mujin enables him to come to a renewed affirmation of his life.

Aberrant hypermethylation of Wnt antagonists has been observed in gastric cancer. A number of studies have focused on the hypermethylation of a single Wnt antagonist and its role in regulating the activation of signaling. However, how the Wnt antagonists interacted to regulate the signaling pathway has not been reported. In the present study, we systematically investigated the methylation of some Wnt antagonist genes (SFRP2, SFRP4, SFRP5, DKK1, DKK2, and APC) and their regulatory role in carcinogenesis. We found that aberrant promoter methylation of SFRP2, SFRP4, DKK1, and DKK2 was significantly increased in gastric cancer. Moreover, concurrent hypermethylation of SFRP2 and DKK2 was observed in gastric cancer and this was significantly associated with increased expression of ${\beta}-catenin$, indicating that the joint inactivation of these two genes promoted the activation of the Wnt signaling pathway. Further analysis using a multivariate Cox proportional hazards model showed that DKK2 methylation was an independent prognostic factor for poor overall survival, and the predictive value was markedly enhanced when the combined methylation status of SFRP2 and DKK2 was considered. In addition, the methylation level of SFRP4 and DKK2 was correlated with the patient's age and tumor differentiation, respectively. In conclusion, epigenetic silencing of Wnt antagonists was associated with gastric carcinogenesis, and concurrent hypermethylation of SFRP2 and DKK2 could be a potential marker for a prognosis of poor overall survival.
