Purpose: The purpose of this study was to determine the effects of auricular acupressure on menstrual pain, dysmenorrhea and academic stress among college students. Methods: A non-equivalent pretest-posttest design was used. Participants were 57 female students recruited from one college. The treatment group (n=30) received an auricular acupressure on a valid zone and the control group (n=27) received an auricular acupressure on an invalid zone (placebo). The independent t-test and ${\chi}^2$-test were used to examine group differences by using SPSS/Win18.0. Results: Subjects in the treatment group reported much less menstrual pain of premenstrual day (p=.001), 1st day (p<.001), 2nd day (p=.003), and dysmenorrhea (p=.003). Of significance, participants in the treatment group reported much less academic stress (p=.049) following auricular acupressure. Conclusion: The findings support that auricular acupressure is effective in controlling menstrual pain and academic stress related to menstruation. As the method is simple it would be useful for women students to be taught and encouraged to utilize this method to mitigate the symptoms related to menstruation through self care.

Studies on some biodegradable polymers and other materials such as hydrogels have shown the promising potential for a variety of surgical applications. Postoperative adhesion caused by the natural consequence of surgical wound healing results in problems of the repeated surgery. Recently, scientists have developed absorbable anti-adhesion barriers that can protect a tissue from adhesion in case they are in use; however, they are dissolved when no longer needed. Although these approaches have been attempted to fulfill the criteria for adhesion prevention, none can perfectly prevent adhesions in all situations. Overall of this work, a new method to fabricate an anti-adhesion membrane using biodegradable polymer and hydrogel has been developed. The ideal barrier for preventing postoperative adhesion would have the following properties; it should be (i) resorbable (ii) non-reactive (iii) easy to apply (iv) capable of being fixed in position. In order to fulfill these properties, we adopted solid freeform fabrication method combined with surface modification which includes the hydrogel coating, therefore, inner or outer structure can be controlled and the property of anti adhesion can be improved.

In order to study the effects of Jengjengamiyjintang on the duodenal ulcer induced by HCl-aspirin in rats, the changes of histological profiles, goblet cells(PAS-positive cells), and the distribution and frequency of cholecystokinin(CCK)-8 and serotonin-producing gastro-entero-endocrine cells were observed after oral administration of Jengjengamiyjintang. Histologically, very severe injury to duodenal epithelium were observed in control groups and these injuries were increased with time intervals. But in the Jengjengamiyjintang administrated groups, no gross lesion of ulcer were demonstrated and histologically minor injury to the mucosal epithelium were observed. PAS-positive cells were increased in the Jengjengamiyjintang administrated groups compared to that of control groups. Severe degranulation of CCK-8- and serotonin-immunoreactive cells were observed in control groups but these phenomenon was seldom in the Jengjengamiyjintang administrated groups. Serotonin-immunoreactive cells were significantly decreased in control groups but increased in Jengjengamiyjintang administrated groups compared with control groups. According to these result, it is suggested that Jengjengamiyjintang would accelerat the healing of the duodenal ulcer but the functional mechanisms were unknown.

The maxillary posterior edentulous region presents unique and challenging conditions in implant dentistry. The height of the posterior maxilla is reduced greatly as a result of dual resorption from the crest of the ridge and pneumatization of the maxillary sinus after the loss of teeth. Materials previously used for sinus floor grafting include autogenous bone, allogeneic bone, xenogenic bone and alloplastic materials. Autogenous bone is the material of choice, but its use is limited by donor-site morbidity, complications, sparse availability, uncontrolled resorption and marked volume loss. One way to overcome this problem would be to use bone substitutes alone as a osteoconductive scaffold for bone regeneration from the residual bone or in combination with allogeneic bone, which also has osteoinductive properties. The purpose of this article is to describe a double layers technique of demineralized and mineralized bone graft materials instead of autogenous bone in sinus floor augmentation of deficient posterior maxillary alveolar process and to report our experience with this technique. Our results show that maxillary sinus augmentation using mineralized and demineralized bone materials, when installed simultaneously with the implant or not, is good results for bone healing.

The primary stability of implants is an important factor to predict the osseointegration. Recently, the resonance frequency analysis has been used to measure the primary stability. It is an objective method to monitor the stability of implants during healing phase. This study is to validate the differences in the effect of the osteotome method according to the bone quality as well the thickness of cortical bone. Two hundred seventy implants of 3.75mm in diameter(Neoplant, Neobiotech, Korea) were placed in 135 bovine ribs. The bone quality is classified into 3 classes according to the number of bone marrow spaces which implants would be placed, and then classified into 9 subclasses after the ribs were trimmed. Two implants were placed in 15 specimens of each class. The conclusion were as follows: 1. In case of less dense cancellous bone, the oseotome method is more effective in primary stability rather than the drilling method(p <0.05). 2. If there was cortical bone, it is more advantagous to get stronger primary stability. 3. If cancellous bone is more dense or if cortical bone exists, there is no statistical significance between drilling and osteotome method(p <0.05).

The umbilicus is an important aesthetic component of the abdomen; therefore, its absence is both cosmetically and psychologically distressing to the patient. However, loss of the umbilicus during abdominal surgical procedures is often unavoidable. Umbilical reconstruction is aimed at obtaining a natural, three-dimensional appearance. We propose a simple method for immediate umbilical reconstruction with good long-term results. This technique was used successfully on a patient who underwent tumor excision. A 49-year-old woman presented with a large mass, measuring 5.8×4.0 cm, on her umbilicus. The mass, an epidermal cyst, developed after laparoscopic uterine myomectomy 5 years earlier. Complete excision of the mass resulted in a large defect, and immediate umbilical reconstruction was planned. Our procedure involved apposing and anchoring two opposing flaps onto the abdominal wall, so that the umbilicus would retain its depth over a long period of time. Negative-pressure wound therapy was applied for 72 hours as a mild compressive dressing. No complications were encountered. The healing process was uneventful and the aesthetic outcome was pleasing; a natural-appearing navel was created. The patient was satisfied with the end result. This technique provides a permanent and sufficient depression for the umbilicus.

Purpose: The aim of this study was to assess the possible paracrine effect of bone morphogeneticprotein-2 (BMP-2) at the experimental site on the adjacent control site for validating a rabbit calvarial defect model as a means of verifying the effect of BMP-2. Methods: Sixteen rabbits were divided into two groups (n=8 in each) according to whether or not BMP-2 would be used. Two circular defects (8 mm in diameter) were created side by side, 2 mm apart, in the calvarium of all of the rabbits. In each animal, one of the defects was grafted with either BMP-2-loaded carrier or carrier material alone. The control defects adjacent to these grafted defects, designated CB (the nongrafted defect adjacent BMP-2-loaded carrier-grafted defect) and CC (the nongrafted defect adjacent to carrier only-grafted defect), respectively, were the focus of this study, and were filled only with a blood clot in all of the animals. Histologic observation and histomorphometric analysis were performed at 2 and 8 weeks (n=4 animals per point in time) after surgery. Results: There was no noteworthy difference in the healing pattern, and no statistically significant differences in histomorphometric parameters such as the defect closure, new bone area, or total augmented area between the CC and CB groups. Conclusions: The results of this study suggest that rabbit calvarial defects separated by a distance of 2 mm are suitable for evaluating the effects of BMP-2 and the control defect can be regarded not to be affected by BMP-2 applied defect.

This study seeks to identify the duties and tasks of a social welfare worker when developing a combined death education program for welfare workers using DACUM method. The program would adopt both a medical and humanistic perspective that can be applied to real life. The study period was between March 2 to March 10, 2015. The study was conducted on eight DACUM committee members who are professors in the field of healthcare or humanities and social sciences. Their medical, humanistic and social viewpoints were investigated. The results show that the focus of the education needs to be on 'the acceptance and understanding of death' and 'healing the stress from loss and suicide prevention'as tasks under the duty of 'loss and mourning'. The tasks for the duty 'the need for death education'were identified as 'death in traditional society and death in contemporary society' as well as 'understanding of issues related to death'. The results show that there is a need to develop death education programs that emphasize healing for the acceptance and understanding of death from a humanistic perspective.

Mineral trioxide aggregate (MTA) would influence healing of periapical tissues by modulating the production of growth factors and cytokines from PDL fibroblasts, however, the studies are insufficient. Therefore, the purpose of this study was to monitor the expression of transforming growth factor-beta1 $(TGF-\beta1)$, fibroblast growth factor-2 (FGF-2), and interleukin-6 (IL-6) from PDL fibroblasts in the presence of MTA. The human PDL fibroblasts were seeded onto the set MTA or IRM at a level of $1\times10^5$ cells per unit well, and further incubated for 6, 12, 24, and 48 hours. The levels of $TGF-\beta1$, FGF-2 and IL-6 from the supernatant were measured by enzyme-linked immunosorbent assay (ELISA) The data were analyzed using one-way ANOVA. The level of $TGF-\beta1$ was down-reg ulated when the cells were grown in the presence of MTA except at 6 hours. The levels of FGF-2 release were significantly suppressed when PDL fibroblasts were grown in the presence of MTA or IRM at all time intervals (p < 0.05). The expressions of IL-6 from MTA treated co)Is were comparable to those of untreated control cells throughout the observation periods. We presume that this material inhibits the stimulatory function of growth factors on granulation tissue formation and in turn, it promotes the healing process modulated by other bone-remodeling cells.
