Objectives: The aims of study were developing cut-off value of Yin-deficiency questionnaire (YDQ) for diagnosis of Yin-deficiency (YD) and compare diagnostic ability between YDQ and Yin-deficiency scale score (YDS) in xerostomia patients. Methods: We recruited 58 xerostomia patients. They were diagnosed YD or non-YD by 3 Korean medicine doctors (KMD). We assessed YD using YDQ and YDS. We evaluated xerostomia using VAS, Dry Mouth Symptom Questionnaire (DMSQ), Salivary Flow Rate (SFR), oral moisture on buccal mucosa and tongue surface (OMB and OMT). We surveyed tongue coatings using Winkel Tongue Coating Index (WTCI). Results: We diagnosed 23 patients YD and 35 patients non-YD. There were no significant differences of age, sex and body mass index between the YD and non-YD groups. Using receiver operating characteristic curve analysis, the optimal cut-off value of YDQ was defined as 304. Sensitivity, specificity and Youden index of YDQ were 86.96%, 71.43% and 1.5839 respectively. Using Cohen's coefficient of agreement, we found that degree of agreement between KMD and YDQ diagnosis was moderate (${\kappa}$=0.524, p<0.001). Using Pearson's correlation analysis, we found concurrent validity of YDQ and YDS were significant correlated. Using area under curve value, we found diagnostic ability between YDQ and YDS were not significantly different (p=0.505), but there were more strong correlations between DMSQ-symptoms and YDQ (r=0.731, p<0.001) than correlations between DMSQ-symptoms and YDS (r=0.418, p<0.01). Conclusions: The cut-off value of YDQ can diagnose YD in xerostomia and diagnostic ability of YDQ in xerostomia is better than YDS.

Objectives : This study was designed to investigate the difference between genuine and pseudo halitosis about qi stagnation and stress. Methods : We recruited 63 halitosis patients who visited the halitosis clinic in the Kyung Hee University Korean Medicine Hospital from June 2012 to August 2013. We classified the halitosis patients into two groups, genuine and pseudo halitosis based on organoleptic assesment (OLT) score and evaluated the severity of self-reported halitosis using visual analog scale (VAS), amount of sulfide compounds using Halimeter, qi stagnation level using qi stagnation questionnaire and stress levels using heart rate variability (HRV) parameters. Results : Comparing the genuine halitosis group and the pseudo halitosis group, there was no significant difference in VAS of halitosis but significant difference in halimeter score. Distribution of qi stagnation and non-qi stagnation groups was significantly different between genuine and pseudo halitosis. Compared to the genuine halitosis group, the pseudo halitosis group showed a significant higher value of low frequency/high frequency ratio (LF/HF ratio). Conclusions : The result of this study suggest that there is significant difference about qi stagnation and stress level between genuine halitosis and pseudo halitosis patients, so when approaching pseudo halitosis patients, we should consider their psychological and emotional status.

A starch degrading fungi was isolated from nuruk, a Korean traditional starter culture made with wheat flour. This newly isolated fungi was identified as Rhizopus oryzae WCS-1 via internal transcribed spacer region sequencing. Enzymatic assays for starch degradation activities indicated an optimum temperature and pH of 55oC and pH 4.0, respectively, using partially purified enzymes from R. oryzae WCS-1. Mixed cultures with S. cerevisiae CEN-PK 2-1D, L2612, BY4742, and D452-2 were performed. S. cerevisiae CEN-PK 2-1D has a maltose utilization pathway and showed the highest ethanol production rate with low maltose concentrations. Addition of 5 mM NaCl to mixed cultures of R. oryzae WCS-1 and S. cerevisiae CEN-PK 2-1D resulted in 21 and 33% improvements in the starch consumption rate and the ethanol production rate, respectively, because Na+ stimulated the starch degradation activity of partially purified enzymes from R. oryzae WCS-1.

We report a case of intracranial foreign body granuloma that showed features of a high grade tumor on magnetic resonance (MR) imaging. However, the relative cerebral blood volume was not increased in the enhancing mass on perfusion MRI and the choline/creatine ratio only slightly increased on MR spectroscopy. The results suggest that the lesion is benign in nature. Perfusion MRI and MR spectroscopy may be helpful to differentiate a foreign body granuloma from a neoplastic condition.

An intrahepatic pseudoaneurysm is a rare complication following transjugular liver biopsy. Transarterial embolization is considered a safe and effective treatment for treating pseudoaneurysms. Herein we report three cases of intrahepatic pseudoaneurysms following transjugular liver biopsies. The three pseudoaneurysms were managed by the following methods: transarterial embolization, percutaneous transhepatic embolization, and close observation.

The purpose of this thesis is to define the relationship between sports desire, study satisfaction and intention to exercise adherence in students, who learn dance sports in cultural physical curriculum. This exercise set students for population, who learned dance sports in cultural physical curriculum at university and used 293 samples for the final study by convenience sampling method and derived some conclusions as following First, sports desire impacts study satisfaction. Namely ostentation desireimpacts mental factor and social factor Enjoyment desire impacts physical factor, educational factor and social factor Desire of body figure impacts mental factor, physical factor, educational factor and social factor Second, sports desire impacts continue intention of exercise Namely, enjoyment desire and desire of body figure impact possibility to exercise adherence and intention to exercise adherence Third, study satisfaction impacts intention to exercise adherence Namely, mental factor impacts possibility to exercise adherence and intention to exercise adherence Physical factor impacts intention to exercise adherence and social factor impacts possibility to exercise adherence and intention to exercise adherence
