  • Background Various shapes and designs of the gluteal artery perforator flap have been used for treating sacral pressure sores and reconstructing breasts. To establish the ideal fasciocutaneous flap design for use in the gluteal area, the soft tissue thickness distribution was measured. Methods Twenty-one buttocks of adult Korean cadavers were analyzed through rectangular subfascial dissection. Each buttock was divided horizontally into 10 sections and vertically into 10 sections, and then, the thickness at the corners of the sections was measured. For the sake of comparison and statistical verification with living bodies, computed tomography (CT) images of 120 buttocks of patients were randomly selected. Five horizontal sections and 4 vertical sections were made, and the thickness at each corner was recorded. Results According to the dissection and the CT images, the area with the thinnest soft tissues in the buttock was around the posterior superior iliac spine, close to the sacral area. The thickest area was the superolateral area of the buttock, which was 3.24 times and 2.15 times thicker than the thinnest area in the studies on cadaver anatomy and the CT images, respectively. Conclusions The thickness of the soft tissues in the buttocks differed by area. The superolateral area had the thickest soft tissues, and the superomedial area had the thinnest. This study includes information on the distribution of the thickness of the gluteal soft tissues of Koreans. The outcome of this study may contribute to the design of effective local flaps for pressure sore reconstruction and free flaps for breast reconstruction.

  • Background: Fibromyalgia (FM) is a complex disorder characterized by widespread chronic pain and tenderness in the muscles, ligaments, and soft tissues. It is a chronic pain condition often accompanied by other symptoms and comorbidities. To effectively manage FM, it is crucial to obtain fundamental epidemiological data pertaining to the target population. Therefore, this study was conducted to elucidate the epidemiological characteristics of FM in the Korean population. Methods: Population-based medical data of 51,276,314 subscribers to the National Health Insurance Service of Korea from 2014 to 2018 were used in this study. Results: The overall incidence of FM ranged from 441 (2014) to 541 (2018) cases per 100,000 person-years, with a higher prevalence observed among female patients compared to male patients. The incidence gradually increased until middle age, followed by a decrease. The highest incidence rates were observed in the fifth decade of life for females and the sixth decade of life for males. When categorizing the affected parts of the body, the shoulder region was observed to be the most frequently affected. A comparison of the drug prescriptions based on medical specialty showed that antidepressants were the most commonly prescribed medications. The management of FM leads to consistent increases in medical expenses, regional disparities, and variations in prescription patterns across different medical specialties. Conclusions: The findings of this study will not only contribute to the understanding of FM characteristics but also provide a vital foundation for efficient management of FM in Korea.

  • To clarify the clinical utility of the calvarial bone graft in the maxillofacial reconstruction, we performed on anatomical study by measuring the regional thickness of the parietal bone on 17 Korean adult dry skulls. Before the sectioning the calvarium, the anatomical landmarks were marked on each specimens. And then we measured the total thickness of the parietal bone, the thickness of the outer and inner cortical plates on various points in each sections of parietal bones using a digital caliper under the stereomicroscope. The total thickness of the parietal bone was ranged from 5.17mm to 7.50mm, and there were no statistical difference in the total thickness of the parietal bone on the same points bilaterally. But there was a tendency that the thickness of the parietal bone was thicker toward to the lambda point than the coronal suture area. At the other hand, the thickness of the outer and inner plate of the parietal bone was the thickest at the first point of the right aspect on the line 1, the first point of the left aspect on the line 5, respectively. In conclusion, this study showed that the donor site of the parietal bone for the maxillofacial reconstruction should be located at more posterior and medial area of the parietal bone than the prevalent known donor site.

  • Waste disposal problem is one of the most important social welfare indicators in urban area, because the volume of waste generated from urban area is remarkable. So far most waste of Seoul has been disposed at landfills. However, this landifill disposal method is confronted with several difficulties in recent. As public concern on environmental problem increases and autonomy system is settled down, local community people of the landfills refuse to receive the waste produced other places any more. It brought reginal confliction problem between waste sending and receiving by refusing to accept waste from certain region. Furthermore, it is difficult to find another place to fill up the waste, while the existing landfiis is reached at the limit in the near future. In terms of environmental aspects landfill method is not the best way to dispose waste. It contaminates the soil and ground/underground water by leaking water containing many serious pollutants as well as offensive oder. In terms of equity, this waste disposal method is not fair. Environmental pollution causes damage to residence near to the landfills, while the waste produced other places. In order to satisfy the equity aspect, the waste generated a region should be disposed within the region. Incineration of Waste has been provided as the alternative. Government plans to construct waste incinerator in every anatomy, so the waste produced by local community is disposed within their local autonomous area. However, the location decision is not easy, since waste incinerator is one of the facilities to the community people. We can not apply the existing location models for this problem, because they show strong NIMBY phenomenon for the location. The location of waste incinerator should be determined very carefully with consideration of various location factors and criteria. This study proposes a methodology for determining the location of the waste incinerators by utilizing GIS, which is a power research tool for location decision where various geographical factors related. We drive the location factors which should be considered in the determination of waste incinerators. They involve environmental, socio-economic, and institutional factors. In first, we eliminate the area which is located within the environmental location criteria such as slope, fault line, distance to river, and then eliminate ares which is conflict with the social and institutional criteria.

  • Objectives : This study aimed to evaluate the anti-stress effects of Guibi-tang and Yisiungyojae-dan on the contents of monoamines in the regional brain of mice immobilized stress. Methods : The experimental animals were immobilized in stress cylinder(height: 15cm, diameter: 3cm) for 15 minutes, and administered of Guibi-tang(6.0mg/10g) and Yishingyojae-dan(9.3mg/10g) water extracts for 7 days before stress. The monoamines contents were measured by HPLC method in various part(frontal cortex, hypothalamus, corpus striatum and hippocampus) of mice brain. Results: 1. In frontal cortex, the contents of norepinephrine were decreased with statistical significantly in Yishingyojae-dan administered group compared to control group. The contents of serotonin were decreased with statistical significance in all of the administered group compared to control group. 2. In hypothalamus, the contents of norepinephrine were decreased with statistical significantly in Yishingyojae-dan administered group compared to control group. The contents of serotonin were decreased with statistical significance in all of the administered group compared to control group. 3. In corpus striatum, the contents of dopamine were decreased with statistical significantly in Yishingyojae-dan administered group compared to control group. The contents of serotonin were decreased with statistical significance in all of the administered group compared to control group. 4. In hippocampus, the contents of serotonin decreased with statistical significantly in Yishingyojae-dan administered group compared to control group. Conclusions: This study shows that Guibitang and Yishingyojae-don are significantly effective on reducing and preventing stress in mice. In addition, Yishingyojae-dan is more clear effective than Guibi-tang on the monoamines change in the mice brain.

  • 해양심층수(deep seawater, DSW)는 청정성과 무기물질의 풍부함 때문에 여러 분야에 응용하기 위하여 최근 많은 관심을 받고있다. 본 연구에서는 동해 양양 부근의 해저 1,100 m에서 취수하여 역삼투압 시스템으로 탈염과 농축을 한 심층수가 배양한 흰쥐해마신경세포의 형태적 분화에 미치는 영향을 조사하였다. 10%(v/v) fetal bovine serum이 첨가된 MEM 배지에서 키운 세포와 비교할 때 25%(v/v) DSW이 포함될 경우 배양 17시간째에는 차이가 없었다. 그러나 DIV3, 7, 14, 및 17에 관찰하면 경도 0 및 200의 DSW가 포함된 배지에서 자란 신경세포는 가지돌기의 수가 현저히 줄었다. 반면에 경도 600의 DSW에서 자란 신경세포는 그 가지돌기의 수가 대조군과 비슷하였으며, 경도 1000의 경우는 대조군에 비하여 거의 2배 증가하였다. 이 결과는 적당한 경도의 DSW는 신경세포의 성장 및 건강을 돕는 것으로 해석된다.

  • The present study describes histochemical properties of the mucosubstances in the pedal sole of abalone, in relation to two main additional functions known to date. Only neutral mucosubstances were demonstrated in the lateral epithelium of the pedal sole of the abalone, however, two distinct types of cells, one containing neutral and the other containing acidic mucosubstances, were identified in the ventral epithelium. The epithelial mucocytes distributed throughout both epithelial and subepithelial glands located in the ventral subepithelial region showed a mixture of neutral and acidic mucosubstances. However, acidic mucosubstances were found in larger amounts than neutral ones in epithelial mucocytes, and vice versa in subepithelial glands. Among these acidic mucosubstances, sulphated substances were dominant. Lesser amounts of carboxylated substances also occurred together with low levels of neuramic and sialic acid. Collectively, the notable morphological differences between abalone and other gastropoda were observed in the ventral surface of the foot, which showed a tall columnar epithelium, peripherally concentrated mucocytes, and subepithelial glands. Mucosubstances are presumably produced by these cells and may also play a role in clinging to some substances to support abalones in addition to the main functions of lubrication and protection.

  • The functional deformity following removal of the maxilla is considerable, especially following maxilla cancer excision. Rehabilitation of oral and maxillofacial region used to be very difficult with prosthesis or traditional flaps. Temporal muscle and fascia flaps have been described for immediate reconstruction following hemi-maxillectomy, but not total maxillectomy. The muscle and superficial fascia of the temporal area differ in their physical characteristics, vascular supply and clinical applications. Both can be employed independently or simultaneously as regional flaps in the reconstruction of a variety of complex craniofacial defects. Four case is presented in which 3 case maxilla cancer, one case non-union after maxilla fracture, and all case showed successful use of this flap. Only one patient developed partial necrosis of the flap ; significant necrosis did not occur in any other patient. This present paper reviews the anatomy, surgical technique and utilisation of temporal muscle and fascia flaps.

  • Detailed human gross anatomic structures have been characterized. No similar data are available in nonhuman primate species in spite of close phylogenic similarity found between man and nonhuman primates. The ever increasing incidence of lung cancer and air pollution related respiratory ailments found in man emphasizes the need for an ideal animal model for studying pathogenesis of these various human pulmonary diseases. Thus, detailed investigation of pulmonary structures found in various species of nonhuman primates is warranted. For determining primate gross pulmonary anatomic structure, published works concerning the number of tracheal cartilage, angle of tracheal bifurcation, caliber of trachea, lung lobe and bifurcation position of trachea recorded for several species of nonhuman pimates, were reviewed. Limited information is available concerning the number of tracheal cartilage, width of tracheal cartilage, angle of bronchus, caliber of trachea and bronchus, and the bifurcation position of the trachea including the length of bronchus on nonhuman primates. Since scanty data have been gathered with no specific reference to their age, sex and body weight, they have no comparative values.
