The aim of this study was to investigate the effect of Fructus Forsythiae on the melanogenesis. To determine whether Fructus Forsythiae methanol extract suppress melanin synthesis in cellular level, HM3KO human melanoma cells were cultured in the presence of various concentrations of Fructus Forsythiae methanol extract and the effects on cell proliferation, tyrosinase activity and melanin contents were examined. Treatment with Fructus Forsythiae methanol extract inhibited tyrosinase activity, regulate melanin biosynthesis as the key enzyme in melanogenesis, in a dose-dependent manner. And also suppressed melanin contents as a dose dependent manner without cytotoxicity morphological change. It was observed that the color of cell pellets was totally different from the control. These results suggest that the inhibitory effect of Fructus Forsythiae methanol extract on melanogenesis is due to the suppression of tyrosinase in HM3KO cells and Fructus Forsythiae is a candidate for an efficient whitening agent.

Purpose: This study is a descriptive research study to determine the level of professional autonomy, professional self-concept, and job satisfaction of emergency nurses, and to investigate their correlations and verify the effects of professional autonomy and professional self-concept on job satisfaction. Method: The subjects were 189 emergency nurses with a work experience of 1 year or more, in 14 hospitals located in B and U Metropolitan Cities. The study was conducted from July 20, 2014, to August 30, 2014. The measurement instruments for professional autonomy, professional self-concept, and job satisfaction were used as the measurement tools. The collected data were analyzed using the t-test, analysis of variance, Scheffe's test, Pearson's correlation coefficient, and multiple linear regression. Results: Job satisfaction among emergency nurses showed a significant positive correlation with professional autonomy (r=.28, p <.001), and with professional selfconcept (r=.50, p <.001) with sub-areas of professional practice (r=.79, p <.001), satisfaction (r=.64, p <.001), and communication (r=.25, p <.001). Factors affecting job satisfaction were satisfaction (${\beta}$=0.60, p <.001), followed by low professional autonomy (${\beta}$=-0.24, p <.001) and communication (${\beta}$=0.14, p =.008), which accounted in total for 48.3% of the effect. Conclusion: This study suggests that enhancing professional satisfaction, maintaining proper communication, and securing autonomy are required to improve the job satisfaction among emergency nurses.

Medical education departments or offices are established in response to public expectations relating to health care, societal trends towards increased accountability, educational developments, increased interest in what to teach and how to educate doctors. However, heavy workloads and mixed feelings towards medical education departments or offices by the other members of a medical school can threaten job satisfaction and increase burnout. The authors investigated the prevalence of burnout among medical education specialists and related issues. Individual in-depth interviews with four medical education specialists were conducted to develop a questionnaire. After content analysis of the interview, the authors generated a survey form with 28 items including 6 categories: motivation to choose medical education as a career, job satisfaction, intention to leave their current position in medical education, the frequency and causes of burnout, and demographics. In September 2013, an email survey was administered to 43 faculty including non-tenure staff who were working in the department/office of medical education in 41 medical colleges in Korea. Of 43 medical education specialists, 25 (60%) returned surveys. Forty three-point-three percent of them felt encouraged when their endeavors generated a visible educational improvement in the medical school. A majority (87%) reported feeling burned out. Fifty percent of them experienced the feeling once or twice a year. The extent of burnout tended to be greater in women, those in their forties, those with non-medical doctor degrees, and in non-tenured staff. To reduce and prevent burnout among medical education specialists, the participants suggested that leadership of medical schools and a systematic approach to medical education should be established. A majority of the medical education specialists reported experiencing burnout, although they were satisfied with their jobs. To reduce their burnout and allow them to focus on their own work in medical education, the following factors are needed: perceptual changes of other members of the college about medical education; more systematic institutional strategies; networking among medical education specialists; and personal efforts for professional development.

Lavandula vera is indispensable member of the herb family, used for perfumes and potpourri. Androgens have profound effects on the physiology of the sebaceous gland. Sebum is secreted due to the effect of androgen, which starts to be secreted at puberty. Using the human sebocyte cell line SZ95. the author investigated the inhibitory effect of Lavandula vera on the lipid production. Light microscopic finding were examined numerous cytoplasmic lipid droplets SZ95 cells by Oil red staining and lipid droplets were increased markedly by testosterone. On the other hand, combined treatment with Lavandula vera and testosterone resulted in a lower lipid droplets than with testosterone alone in a dose-dependent manner. These findings indicate that Lavandula vera acts antagonistically to testosterone and inhibits the lipid synthesis of SZ95 cells at the cellular level.

Background: Instrument players are exposed to occupational musculoskeletal symptoms due to constant movement and strain to meet the needs of their audience. This can cause dissonance between the player and the instrument and can cause medical problems in the musculoskeletal system such as pain, tendinitis, muscle spasms, and joint hyperextension from overuse of body parts. Objective: The purpose of this study is to comparatively analyze the characteristics and occurrence of musculoskeletal symptoms in professional and student players, and to find out the awareness of the need for health care professionals and special exercise programs for orchestra players. Methods: The subjects were professional orchestral musicians 191 from the three symphony orchestras and music students 209 from the four universities volunteered to participate in this study; 393 subjects (98.25%) completed the questionnaire. symptom prevalence and related factors of playing-related musculoskeletal disorders (PRMDs) were surveyed with a self-administered questionnaire. Standardized Nordic Questionnaire was complemented by adding a visual-among scale and used to diagnose PRMD. Results: High prevalence of musculoskeletal complaints in both professional musicians (85.30%) and student musicians (82.30%). Professional musicians and student musicians also suffered the highest problem in shoulder and neck complaints. Significant differences were found between groups that recognized of necessity for specialized health professionals, professional organizations, and special programs for musicians. Conclusions: Professional musicians and student musicians, like orchestra players, are already exposed to overuse syndrome. However, student musicians lack awareness of the risk of injury compared to orchestra players. We suggest that an appropriate treatment management program for the prevention and early treatment of musculoskeletal system damage should be provided to performers at an early stage.

It is the most important thing at present for physicians to posses the qualification of medical professionalism. A lot of medical schools have made all-out efforts to develop leaders of medicine, who will be able to meet the needs of medical professionalism in this complex medical environment. The purpose of this study is to review the cognitive base of medical professionalism leading the curriculum development of medical professionalism. The discussion of medical professionalism started in the 20th century. During the 1960s, there were attempts to reshape the concepts and attributes of medical professionalism. The government began to intervene in the autonomy of physician and the self regulation policy of medical society in 1970s. Physician may be asked to play as a healer and professional (what?) during their medical practice. The fundamental role of healer such as care, compassion, honesty, integrity, confidentiality, ethical behaviors, and respect with patients were nothing fresh to tell even though the age was changed. The attributes of professional which are physician's autonomy, self regulation, teamwork, and responsibility to society has been changed dramatically over the past five decades. In general, medical educators agreed that professionalism is demonstrated through a foundation of clinical competence, communication skills, and ethical and legal understanding, upon which is built application of the principles of professionalism: excellence, accountability, altruism, and humanism. If physicians fail to show professionalism in society, they will confront the crisis which can be under the government control. The only way to keep their autonomy is to practice medical professionalism. So far today, medical schools have laid more stress on competence than value standards in educational systems and it was restricted for medical students to learn the value standards for medical practice. To understand and practice the medical professionalism, it is the most realistic way to solve the complicated medical problems.

An Epidemic disease is regarded as warm disease by Korean Medicine. Warm disease is highly contagious and shows an unfavorable condition, and that is characteristic of being widely prevalent. Warm disease study cope with this epidemic disease opportunely. In the Myeong[明] and Cheong[淸] Dynasty, warm disease study got into the region of Korean medicine of today and "The Sections of Warm Disease(溫病條辨)" contributed to the cause of the study was really great. "The Sections of Warm Disease" written by Ohguktong(吳鞠通) in the Cheong Dynasty are divided into the three sections of Upper burner[上焦], Middle burner[中焦] and Lower burner[下焦]. Ohguktong, dealing with the contents of Defense-aspect[衛分], Gi-aspect[氣分], Construction-aspect[營分], Blood-aspect[血分], and so forth in all "Sections of Warm Disease", made use of Seopcheonsa(葉天士)'s Defense Gi[衛氣], Construction, and Blood pattern identification with Triple burner[三焦] pattern identification and six channel pattern identification. And he, having a correct understanding of the nature of medicine, suggested in detail that the directions of medicine and described the processing according to method and the method to take medicine. To conclude, Ohguktong(吳鞠通) Tong in "The Sections of Warm Disease" not only formulated the system of the practical theory of warm disease but also solidified the foundation covering warm disease and its treatment as well, He established the new method of treatment and formula related to warm disease and made a definite distinction between cold damage[傷寒] and warm disease[溫病].
