Objectives: This study aimed to examine the difference of external appearance measurements in subjects of different regional lineages as subgroups within the Tae-eumin Sasang grouping. Methods: We chose 51 Tae-eumin subjects diagnosed by Korean Sasang constitutional medical doctors aided by voice analysis. The subjects were divided into two groups, the northern and southern lineages, by an expert on facial characteristics of the two lineages. We took pictures of their frontal and lateral views by Martin's method, measured projected length of face with the Facial Feature Measurement Program, and analyzed anthropometric facial differences between the northern and southern types. Results: Results show differences between the northern and southern types. First, the northern type of face has bigger measurements than the southern type on the frontal face. Second, the northern type of face has higher measurements of "height", which means distance from pupil to a specific measurement point, than the southern type on the frontal face. Third, on the frontal face, the northern and southern types have differences with respect to eyebrow, point of sellion, and eye. Fourth, on the side face, the northern and southern types have differences in lip, mandible and ear. Conclusions: We found our anthropometric facial measurements of the northern and southern lineages to be in accordance with previous literature. Knowledge of the differences between the northern and southern lineages can be a hint in constitutional diagnosis when differentiation is clinically confusing.

Introduction: The characteristics of oral tongue squamous cell carcinomas (SCC) and the treatment results were reviewed to determine the appropriate treatment strategies. Materials and Methods: The medical records of 140 patients diagnosed and treated for oral tongue SCC at Yonsei University Health System from January 1995 to December 2004 were reviewed. For statistic analysis, the survival rate was determined using the Kaplan-Meier method with SPSS version 12.0, and the difference in survival rates was evaluated using a log-rank test. Results: The mean age of the patients with oral tongue SCC patients was 55 (19-85 years old). According to the T, N and pathologic stage, the patients were distributed from a higher to a lower incidence of cases, as follows: T2 (46.4%), T1 (37.9%), T4 (8.5%), and T3 (7.1%); N0 (65%), N1 (20.7%), N2 (13.6%), and N3 (0.7%); and stage I (31.4%), stage II(25.7%), stage IV (22.2%), and stage III (20.7%). Local and regional recurrence and distant metastasis was present in 13.6%, 5% and 4.2% of patients, respectively. The five-year survival rate was 72.2%, and the prognostic factors for oral tongue SCC included neck metastasis, pathologic stage of the disease, cell differentiation, treatment modality, neck dissection as part of the treatment plan, and neck node recurrence. Discussion: It is suggested that ipsilateral neck dissection or bilateral neck dissection should be selected as a treatment of tongue SCC patients with advanced stage.

Objectives : Mori Follium (Morus alba L. leaf) has been cultivated in many Asian countries. Especially, mulberry leaf has been used as an anti-diabetic remedy in oriental medicine. However, anti-obesity effect of mulberry has not been unknown. In this study, our objectives of study is to investigate the anti-adipogenic effect of mulberry water extract (MLE) and to reveal potential molecular anti-obesity mechanism in 3T3-L1 adipocytes differentiation model.Methods : The cytotoxicity of MLE in 3T3-L1 was examined by MTT assay. Anti-adipogenic effect of MLE was evaluated by Oil Red O (ORO) staining. To elucidate the molecular mechanism, inhibitor assay was employed. The mRNA expression levels of adipogenic transcriptional factors such as PPARγ and fatty acid synthase (FAS) were analyzed by reverse transcription-polymer chain reaction (RT-PCR) analysis.Results : The MLE treatment for 24 h did not affect to the 3T3-L1 cells at concentrations of 1, 10, 100, 200, 400, 800 and 1,000 ㎍/㎖. Thus, non-toxic concentration rages of MLE were used during adipogenesis period (day -2 to 7). Intracellular lipid accumulation in MLE-treated 3T3-L1 adipocytes (day 6) were quantitatively evaluated by ORO staining. The MLE treatment significantly and dose-dependently suppressed 3T3-L1 adipogenesis by 60.42%, 38.24%, and 5.97% at 10, 100, and 200 ㎍/㎖, respectively. In addition, our inhibitor assay and RT-PCR analysis revealed that the MLE-inhibited 3T3-L1 adipogenesis through inhibition of PPARγ mediated by Wnt/β-catenin signaling pathway.Conclusions : In conclusion, these findings indicate that the MLE could be used in prevent and/or treatment of obesity-related diseases.

Purpose: This study aimed to analyze the impact of increasing the supply of newly licensed nurses on improving the hospital nurse staffing grades for the period of 2009~2014. Methods: Using public administrative data, we analyzed the effect of newly licensed nurses on staffing in 1,594 hospitals using Generalized Estimating Equation (GEE) ordered logistic regression, and of supply variation on improving staffing grades in 1,042 hospitals using GEE logistic regression. Results: An increase of one newly licensed nurse per 100 beds in general units had significantly lower odds of improving staffing grades (grades 6~0 vs. 7) (odds ratio=0.95, p=.005). The supply of newly licensed nurses increased by 32% from 2009 to 2014, and proportion of hospitals whose staffing grade had improved, not changed, and worsened was 19.1%, 70.1%, and 10.8% respectively. Compared to 2009, the supply variation of newly licensed nurses in 2014 was not significantly related to the increased odds of improving staffing grades in the region (OR=1.02, p=.870). Conclusion: To achieve a balance in the regional supply and demand for hospital nurses, compliance with nurse staffing legislation and revisions in the nursing fee differentiation policy are needed. Rather than relying on increasing nurse supply, retention policies for new graduate nurses are required to build and sustain competent nurse workforce in the future.

The Yeongju granitoid batholith is a plutonic complex of huge area (1180km2) intruding the metamorphic rocks of the Yeongnam massif. The batholith, which is divided into fivelithofacies, consists of three separate plutons. The oldest Buseok pluton comprises four lithofacies: hornblende biotite tonalite, porphyrotoc biotite granodiorite, equigranular biotite grandiorite and biotite granite. The middle Chunyang pluton has been called as Chunyang granite that ranges in compostion from granodiorite to granite. The youngest Jangsu pluton is intrusions that has lithofacies of two mica granite. The contact between Buseok pluton and the rest two plutons shows obvious intrusive relations, but relation between the Chunyang and the Jangsu pluton is far away, so gives no indication of relative ages. Changes in nextures and micristructures, as well as in the mineral contents, take place between rock types og the plutons. only the Buseok pluton shows faliations of two type: magmatic foliation and regional mylonal foliation. K-Ar age deteminations fall into 171.7$\pm$3.2~162.3$\pm$3.1 Ma in the Buseok pluton, 153.9$\pm$2.9 Ma in the Chunyang pluton and 145.3$\pm$2.7 Ma in the jangsu Pluton. The batholith presents three separate intrusive phases which range in composition from tonalite to granite to granite. Each intrusive phase apperars to have been intruded in a pulse from an underlying, differentiating magma. The petrochemical data showthat three plutons are within the diagnostic range for continental arc orogenic tectonic setting, whereas Jangsu pluton approaches postorogenic setting. The data suggest that three plutons are calc-aclkalline series, and that temporal compositional variations change progerssively from tonalite through grandiorite to granite between the intrusive phases. so we consider that the magmas for all the phases were probably derived from a differentiation by fractional crystallization of a parental magma. The tonalite magma of the Buseok phase was tapped was tapped from a chamber deep in the crust, and then would have to rise at a rapid rate to its final level of emplacement. The tonalite magma in the chamber was gradually enolved through granodiorite magma into granite magma by fractional crystallization. The magmas of the younger phases were respectively tapped with temporal interval from a evolved magma of the chamber that rose into a shallower lever in the crust, and rose to their present level of emplacement.

This study was conducted on 3,418 cases of cardiopulmonary arrest patients' detailed status table (2020, raw data) collected in 2020. Also, it is a retrospective narrative research that investigates and examines related laws and guidelines. The main findings are as follows. First, the implementation rate of 'bystander CPR' was 30.66% (1047 cases) and it was a remarkable result. It can be inferred the quality of the relevant laws and guidelines. Second, 'Public access defibrillation (shock)' accounted for only 0.10%(5 cases). it is considered that the relevant laws and guidelines are weighted towards 'stock and obligation.' Strategic differentiation of response by region is needed. Third, out-of-hospital cardiac arrest occurred at house was 71.97%(2,640 cases). To operate the 'special ambulance team' efficiently, it is necessary to analyze regional data more closely and develop an efficient strategy in the future.

In this study, the symbols and visual expressions employed in the food culture content of official website designed to promote three cities in Korea, Seoul, Jeonju and Jeju, were subjected to semiotic analysis. In this study, it was assumed that these websites reflected the varying perspectives of the people behind the development and management of these routes of Internet communication, and the semiotic choices made in order to exemplify each city's food cultural image. The aim of the study was to analyze the communication strategies of food cultural branding in the terms of the online content regarding Seoul, Jeonju, and Jeju with a focus on the comparative points in these cities' official websites. This study included conducting semiotic content analyses of the aforementioned cities' official web pages in an attempt to determine the food branding strategies used to differentiation and produce more favorable perceptions of these three cities. Building upon the findings drawn from this comparative study, the present work can be used to determine more effective ways of strategically differentiating the images of local food culture associated with these cities from the view of brand communications. This study also demonstrates viable directions for designing web content for a city where the food cultural messages can be delivered in a thoughtful and effective manner.

The compulsory beef labelling system has launched from January 1st 2007 by the amended Food Hygiene Law, we were checked the actual conditions of beef origin with a nationwide scale by the Hanwoo differentiation specific test method which was developed by Korea FDA using 90 SNP biomarkers. The test method is useful tool to differentiate the beef origin carrying out the mission of KFDA's annual food safety management guidance. Also we have technically transferred the Hanwoo differentiation specific test method to other institutes as well regional KFDA and established the training program as a regular course in Korea Human Resource Development Institute for Health and Welfare. The beef used in this study were collected according to the 2009 Food safety guidance in roast beef restaurants where business site area greater than 100 $m^2$. Total 216 samples were consisted of 48 samples of the Seoul area and 168 of the region. The monitoring result from restaurants in all the region of Korea showed that 3 of 216 Hanwoo-labelled beefs were found out as a non-Hanwoo (1.3%). This results are gradually deceasing trend compared with 34.0% in 2005, 30.1% in 2006, 3.2% in 2007 and 5.14% in 2008. From these data, the Hanwoo differentiation specific test method on the settlement of the compulsory beef labelling system has an important role. As a outcome of this project, we might be considered the early settlement of the compulsory beef labelling system, technically transferred to other institutes and the establishment of regular training program of the test method.

Purpose: Stomach cancer is one of the most common malignancies in Korea, but there is no report on FDG PET in patients with stomach cancer. We observed findings of FDG PET in patients with stomach cancer. Materials and Methods: In 13 patients with pre-operative stomach cancer, PET and CT were performed. Primary lesion and regional lymph nodes detection were aualyzed. Correlation between FDG uptake ratio and each prognostic factor of primary lesion was analyzed. In 19 patients diagnosed as recurrence or displaying suspicious symptoms, conventional work up including tumor marker and PET were performed. Recurrence detection of anastomotic site, distant metastasis, and tumor marker elevation were analyzed. Results: Sensitivity for primary lesion detection was 83.3% (CT 71.4%) and two submucosal lesions were undetected. FDG uptake ratio was variable and had no correlation with invasion-depth, size, Borrmann type, staging and differentiation. Sensitivity for regional lymph node detection was 58.3% (CT 58.3%) and the lesions less than 1cm were undetected. Sensitivity for recurrence detection was 100% but there were three false positives. Sensitivity for distant metastasis detection was 64.3% and significantly higher than that of conventional work-up (21.4%). Average of tumor marker level in patients who were confirmed as recurrence was higher than false positive. Conclusion: PET is more useful than conventional work up in distant metastasis detection when recurrence is suspected. In pre-operative stomach cancer, PET is comparable to CT for detection of primary lesion and regional lymph node metastasis and detection of distant metastasis requires further study.

The purpose of this study was to suggest the improvement of the Mountainous Landscape Impact Review(MLIR) system for the conservation and eco-friendly use of mountain scenery. In order to understand the status of the MLIR system, a comparative analysis was conducted of the MLIR official guidelines and the 100 MLIR reports submitted to the Korea Forest Service from 2011 to 2013. In addition, an Importance-Performance Analysis(IPA) was conducted to take into account stakeholder opinions and to determine the first priorities to be improved upon in operation and functions of the MLIR system. The results of the IPA in evaluating the MLIR system showed that the components in the MLIR system that should be primarily improved are mountainous landscape resource inventory, objective and quantitative selection of viewpoints, and a checklist for examining the damage expected in mountainous lands. To Revitalize the Mountainous Landscape Impact Review system, the professional knowledge and experience of the stakeholders should be enhanced by education and training in the MLIR system over the short-term, while the effective functioning of the MLIR system should be reinforced by differentiation and connectivity of the MLIR system with similar institutions, and by emphasizing the uniqueness and properties of mountainous landscapes over the long-term.
