Objectives : Placebo phenomena have been considered as a confounding factor of clinical trial. Expectancy and belief of acupuncture have not been evaluated quantitatively. The present study was performed to analyze the emotional and cognitive factor of acupuncture and investigate whether the expectancy of acupuncture treatment is associated with the cognition of acupuncture. Methods : The expectancy and the perception of bodily sensation (PBS) of 22 participants were assessed using self-reported questionnaire. The subjects used the self assessment manikin (SAM) to rate each of the standard affective image of the international affective picture system (IAPS) and other acupuncture-related image. Based on the degree of expectancy, the high expectant (HE) and the low expectant (LE) group were classified. The thermal and pressure pain threshold was objectively evaluated using radiant-heat device and algometer. The degree of expected pain of acupuncture and the actual pain of painful stimulation was subjectively evaluated using facial pain scales (FPS).Results : Using SAM analysis, we identified the negative correlation between hedonic valence and arousal dimension on acupuncture-related visual cue. The degree of the PBS and general pain threshold did not show any significant difference between the HE and the LE group. The HE group rated the acupuncture images as more pleasant, more arousing, than the LE group. In addition, we also found that the higher expectancy marked the lower FPS of the expected pain of acupuncture, but not of the actual pain of painful stimulation. Conclusions : Our preliminary study identified the psychological dimensions of acupuncture-related visual cue. These findings indicate that the expectancy of acupuncture could affect the cognition of acupuncture.

Objectives: Clinical improvements can be observed following placebo administrations in clinical trials. Randomized controlled trials have been conducted to disentangle the specific effects of therapeutic interventions over the past decade. In acupuncture trials, non-penetrating placebo needles offer the opportunity to determine the specific effects of needling. Methods: The present review provides an overview of the concept of the placebo effect and the characteristics of the placebo needles. Results: Placebo control can contribute to minimize for bias and the contextual and psychological components of therapeutic interventions. Placebo control should meet two criteria: blinding efficacy (indistinguishable from active treatment) and physiological inertness. In the case of acupuncture, however, it is difficult to meet both criteria simultaneously. The dilemma of placebo needles suggests that placebo needles do not constitute proper control in acupuncture research. Considering the characteristics of placebo needles, patients are more likely to perceive placebo needles as active treatment in acupuncture trials compared to placebo pills in pharmaceutical trials. Placebo response might be observed more frequently to placebo needles than to placebo pills. When acupuncture treatments are utilized in clinical use, placebo effects can be enhanced by exploiting patients' expectations in the contextual or environmental cues that surround medical intervention. Conclusions: We have to consider these unique characteristics of placebo needles in order to avoid drawing premature conclusions that acupuncture itself is just a placebo.

This study proposes an enhanced structural health monitoring method for an automatic gauge changeover system (AGCS) using digital image correlation (DIC) analysis. Due to the difference in gauge width by country, railway vehicle operation between continents is limited. As a remedy, AGCSs have been developed and have shown advantages in transition speed and operational cost, compared with the traditionally used freight trans-shipment and bogie exchange. Following a simplified operational test, we identified that strict regulation is required for gauge width before a vehicle enters the gauge changing section. To monitor the potential deformation in the railroad track, damage identification based on DIC was introduced. A testbed for the AGCS and monitoring system was then constructed at the Osong vehicle depot. For the establishment of an effective monitoring system, shadows in images and camera location effects were investigated. The proposed monitoring technique was validated by analyzing images before and after the reciprocating operation of an AGCS bogie vehicle and used to determine the presence of damage.

Objectives : DongUiBoGam is one of the representative medical literatures in Korea. We used text mining methods and analyzed the characteristics of the indications of each meridian in the second chapter of DongUiBoGam, WaeHyeong, which addresses external body elements. We also visualized the relationships between the meridians and the disease sites. Methods : Using the term frequency-inverse document frequency (TF-IDF) method, we quantified values regarding the indications of each meridian according to the frequency of the occurrences of 14 meridians and 14 disease sites. The spatial patterns of the indications of each meridian were visualized on a human body template according to the TF-IDF values. Using hierarchical clustering methods, twelve meridians were clustered into four groups based on the TF-IDF distributions of each meridian. Results : TF-IDF values of each meridian showed different constellation patterns at different disease sites. The spatial patterns of the indications of each meridian were similar to the route of the corresponding meridian. Conclusions : The present study identified spatial patterns between meridians and disease sites. These findings suggest that the constellations of the indications of meridians are primarily associated with the lines of the meridian system. We strongly believe that these findings will further the current understanding of indications of acupoints and meridians.

Purpose: Prostate biopsy is a conventional method for the detection of prostate cancer in men with suspicious findings. However, there is no universal agreement on which method is the better approach to the prostate, with regard to cancer detection rate and complication rate. In this prospective randomized study, we compared cancer detection rates and complication rates between transperineal (TP) and transrectal (TR) prostate biopsy. Materials and Methods: Between March 2006 and December 2007, we analyzed 200 Korean men. One hundred patients underwent randomized TP prostate biopsy and 100 patients underwent TR prostate biopsy. All biopsies were extended 12-core biopsies. With both approaches, 12 biopsy specimens were obtained systematically from the peripheral and transitional zones, including the apex, base, and transitional zone. The patient’s subjective pain scale was measured by use of visual analogue scales. Immediately after the biopsy, the pain score was independently recorded by the patients. One week later, various complications were measured by answer note. Results: The overall cancer detection rate was 22% (22 of 100 patients) with TR prostate biopsy and 29% (29 of 100 patients) with TP prostate biopsy. Considering the prostate cancer detection rate, there were no significant differences between the groups for prostate-specific antigen (PSA), age, body mass index (BMI), and prostate volume. Apart from the cancer detection rate and complication rate, the pain scale, in each different approach, was statistically meaningful. Conclusions: There were no significant differences in the cancer detection rate or complication rate between TP and TR prostate needle biopsy. However, with regard to pain relief and complication rates, TR prostate needle biopsy is preferable.

Oriental cosmetics is based on oriental medical theory. In oriental medicine, skin reflects the condition of internal organ(臟腑) and qi-hyul(氣血). The oriental dermatology and aesthetics aim at the development of health and beauty using herbal medicine, acupuncture, chuna(推拿), qigong(氣功), and diet. And the oriental dermatology and aesthetics are related the branch of oriental medicine, such as oriental gynecology and oriental internal medicine.
