Purpose: This study investigated the association between the objective indicator of masticatory function assessment and the masseter muscle thickness (MMT) using ultrasound imaging. Methods: A total of 99 subjects (males: 24, females: 75, mean age: 76) were analyzed. The maximum bite force (MBF) was measured with a pressure-sensitive sheet and an image scanner. The mixing ability index (MAI) was calculated by image analysis after asking the subjects to chew a wax specimen. The MMT during rest and clenching were obtained with a diagnostic ultrasound system, and the difference in MMT during rest and MMT during clenching was defined as the difference in masseter muscle thickness (DMMT). Multiple regression analysis was performed to determine the independent variables affecting MBF and MAI. Results: The MBF showed correlation with the number of remaining teeth (β=0.346, p=0.002) and DMMT (β=0.251, p=0.011). The MAI correlated with only the number of remaining teeth (β=0.476, p<0.001). Conclusions: The DMMT reflects the state of masseter muscle contraction, and can be used as a predictor as well as the number of teeth when assessing masticatory function.
Objectives : This report intended to estimate effects of Jung-an acupuncture on the acquired torticollis caused by muscle contraction. Methods : The patients were treated by Jung-an acupuncture, herb medication and Physical treatment daily. The improvement of the patients was judged by Toronto Western Spasmodic Torticollis Rating Scale(TWSTRS), Tsui's score and Visual Analogue Scale(VAS). Results : After 7 days of treatment, the 2 patients' neck pain and cervical movement were improved. Also, TWSTRS score, Tsui's score and VAS were all reduced. Conclusions : As the Jung-an acupuncture's theological base is organized with meridian theory and myofacial release therapy, We considered the Jung-an acupuncture is effective not only for the skin disease but also for the muscle problem such as torticollis.

Disorders of sex development (DSD) are congenital conditions characterized by atypical development of chromosomal, gonadal, and phenotypic sex. 46, XY DSD can result from disorders of testicular development or disorders of androgen synthesis/action. Prophylactic gonadectomy should be considered in patients with 46, XY DSD because of the increased risk of gonadal malignancy. We report two rare cases of 46, XY DSD, including XY pure gonadal dysgenesis and complete androgen insensitivity syndrome, who underwent a prophylactic gonadectomy.
Objectives: The purpose of the study was to investigate factors affecting the assessment of objective and subjective masticatory ability in the elderly, and to evaluate masticatory ability assessment more accurately. Methods: A total of 112 participants were recruited after oral examination in senior citizen welfare facilities. The participants' masticatory ability was evaluated objectively (Mixing ability index; MAI), and subjectively (Key food intake ability; KFIA). Participants' general characteristics and oral health-related variables were also recorded. Based on masticatory ability assessment, participants were classified as either high or low. IBM SPSS Statistics Ver.23.0 was used for all analyses, including descriptive statistics, Chi-square test, Mann-Whitney U test, Spearman rank correlation, and Logistic regression analysis. Results: Higher masticatory ability was positively correlated with higher scores on MAI and KFIA. Additionally, there was a significant positive correlation between MAI and KFIA. When analyzing factors affecting objective and subjective masticatory ability assessments, Functional tooth units (FTUs) were revealed as a related factor. In subjective masticatory ability assessment, oral moisture, difficulty in chewing, and the Geriatric Oral Health Assessment Index (GOHAI) were also influential factors. Conclusions: In order to accurately assess masticatory ability, it is necessary to use both objective and subjective measures. Additionally, to improve the masticatory ability in the elderly, treatment should be provided to improve overall oral health and satisfaction.
On october 26 1909, An Jung-geun killed Ito Hirobumi in Harbin. This study examined making public opinion of Daehan Mseil Sinbo about that ‘Harbin incident'. Daehan Maeil Sinbo was paid attention to the following : 1) Daehan Mseil Sinbo informed of ‘Harbin incident' in detail, 2) in addition, presented Korean the future tasks. First, Daehan Maeil Sinbo described ‘Harbin incident' not asssasination but justified deed for Korea independence. In addition, aroused public opinion in this direction. Second, Daehan Mseil Sinbo described An Jung-geun as Hero who devoted himself for Korean independence. Moreover Daehan Maeil Sinbo showed him as role model of Korean. That is, He was not an assassin. Third, Daehan Maeil Sinbo drew the present task from the deed of An Jung-geun. Daehan Maeil Sinbo presented the War of Independence as method for Korean independence. And Daehan Maeil Sinbo made aware of the necessity of the preparations for the War of Independence to the mass of people. At the same time, Daehan Maeil Sinbo called attention to the unified action of Korean. Finally, Daehan Maeil Sinbo sympathized with against imperialictic region uinfication, which An Jung-geun presented in the theory of Oriental Peace. In according to, Daehan Maeil Sinbo aroused public opinion against annexation of Korea by Japan.
Curled dock (Rumex crispus L.) is known to have several health benefits including antioxidant, antifungal,and anti-inflammatory effects. The potential to induce phase 2 detoxifying enzymes of butanol extract of curled dock (BECD) seeds was investigated. BECD increased the activity of NAD(P)H:quinone oxidoreductase and expression of phase 2 detoxifying enzymes such as heme oxygenase 1, γ-glutamylcysteine synthetase, NAD(P)H:quinone oxidoreductase,and glutathione reductase, in both hepa1c1c7 and its mutant BPRc1 cells. The translocation of transcription factor nuclear factor-erythroid 2 p45-related factor 2 (Nrf2) and binding to antioxidant response element (ARE) in the promoter region of phase 2 detoxifying/antioxidant enzymes were promoted by BECD in HepG2-C8 cells. Furthermore,BECD enhanced phosphorylation of Akt in hepatoma cell lines while Nrf2 activation induced by BECD was suppressed by an inhibitor of Akt. This result suggests that BECD induces phase 2 detoxifying enzymes through the Akt/Nrf2/ARE signaling pathway. BECD merits further study to be developed as detoxification agent.
The purpose of this study is to assess the associations among person-environment fit, organizational citizenship behavior, organizational commitment and turnover intent in the foodservice industry. The study was administered to 306 Korean employees. The results indicated a positive relationship between person-environment fit, employees' organizational citizenship behavior and organizational commitment. However, person-environment fit did not have a significant, direct impact on their turnover intent. Thus, this study found an indirect influence via organizational citizenship behavior and organizational commitment. In addition, organizational citizenship behavior and organizational commitment were negatively associated with employees' intention to leave the organization. Limitations and future research directions are also discussed.
For the agile development methodology that repeats the frequent releases and the short development periods, there are some value practices that we have to keep. Among them, three typical practices were selected: use of Web 2.0 collaboration tool, adoption of the test driven development (TDD) and refactoring. The agile practice that forces the communication between team members was defined with the use of Web 2.0 collaboration tool. When this is applied to the development method of open-source projects which are dispersed geographically, temporally and culturally, it is expected to raise the satisfaction of OS project users and to contribute the maturity of community. It was applied to the study models that were drawn out from the precedent studies. Today, OS project users are adopting diverse tools for the online communication. But the degree of communication that is emphasized in the agile methodology can be satisfied only with the use of two-way, open and communicable tools reflecting the characteristics of Web 2.0 rather than with the conventional one-way information transmitting tool. In this situation, it was examined how the conventional and the improved tools have influence on the users' satisfaction. This paper is focusing on the communication factor among 3 factors.
