본 연구는 기존 구도심부 상업지역의 공동화로 인한 쇠퇴현상이 나타나고 있어 현 시점에서 진주시의 도시공간구조를 살펴보고자 하였다. 도시공간구조 분석의 범위는 구득자료의 한계와 연구의 목적을 감안하여 진주시의 동지역으로 한정하였다. 진주의 도시공간구조를 밝히기 위하여 다변량해석(Multivariate Analysis)을 사용하여 분석한 결과 7개의 지역(중심지, 공업지, 일반주거지 등)으로 유형화할 수 있었다. 진주시는 장래 낙후된 도시이미지의 쇄신, 서부경남의 중심도시로의 부활을 위해서는 앞서 지역별 현상을 감안하여 도심 노후지역의 전면적인 도심재개발, 재건축사업 및 재정비촉진사업 등이 필요할 것으로 보이며, 상평공단 이전 및 초장동 일원과 연계한 신도시 건설, 현재 계획 중인 혁신도시의 차질 없는 추진이 필요할 것으로 판단된다.

The purpose of this study is to examine the effect of personal psychological variables(cognitive flexibility, emotion dysregulation, subjective health condition), family variables(marital satisfaction, father-adolescent communication) and job satisfaction on the psychological well-being of middle-aged men. For this research, questionnaires were administered to 550 middle-aged men residing in Seoul, Gyeonggi and Incheon. Among 352 questionnaires collected, 327 were selected and statistically analyzed by average, standard deviation, frequency analysis, t-test, one-way ANOVA, and hierarchical regression analysis using SPSS Win 21.0. The main results of the study are as follows: First, according to middle-aged men's social-demographic variables, the level of their psychological well-being differed significantly. Second, cognitive flexibility was the most significant predictor of their psychological well-being. In addition, emotion dysregulation, job satisfaction, father-adolescent communication, and subjective health condition were significant predictors. These results suggest that cognitive reconstruction training or problem-solving intervention could be useful for the psychological well-being of middle-aged men.

The filamentous Ascomycota Colletotrichum gloeosporioides sensu lato is a fungus that has been reported worldwide as a causal agent of anthracnose disease in avocado and other crops. In Mexico, this species affects fruits from an early stage of development in the orchard until the post-harvest stage. Although fungicides are continuously applied to control Colletotrichum species, pericarp cankers and soft rot mesocarp in fruits are still frequently observed. Considering the lack of a precise description of the causative agent, the aim of the current study was to determine the pathogens involved in this symptomatology. Twenty-four isolates were consistently obtained from the pericarp of avocado fruits cv. "Hass" collected in the central avocado-producing area of Mexico. Morphological features such as colony growth, conidia size, and mycelial appressorium were assessed. Bayesian multilocus phylogenetic analyses were performed using amplified sequences of the internal transcribed spacer region of the nuclear ribosomal DNA; actin, chitin synthase, glyceraldehyde-3-phosphate dehydrogenase partial genes; and APn2-Mat1-2 intergenic spacer and mating type Mat1-2 partial gene from the nine selected isolates. In addition, fruits were inoculated with a conidial suspension and reproducible symptoms confirmed the presence of Colletotrichum fructicola in this area. This pathogenic species can now be added to those previously reported in the country, such as C. acutatum, C. boninense, C. godetiae, C. gloeosporioides, and C. karstii. Disease management programs to reduce the incidence of anthracnose should include C. fructicola to determine its response to fungicides that are routinely applied, considering that the appearance of new species is affecting the commercial quality of the fruits and shifting the original population structure.

Presented in this paper are the experimental results that measure rapid prototyping (RP) errors in 3D medical models. We identified various factors that can cause dimensional errors when producing RP models, specifically in maxillofacial areas. For the experiment, we used a human dry skull. A number of linear measurements based on landmarks were first obtained on the skull. This was followed by CT scanning, 3D model reconstruction, and RP model fabrication. The landmarks were measured again on both the reconstructed models and the physical RP models, and these were compared with those on dry skull. We focused on major sources of errors, such as CT scanning, conversion from CT data to STL models, and RP model fabrication. The results show that the overall error from skull to RP is $0.64{\times}0.36mm(0.71{\times}0.66%)$ in absolute value. This indicates that the RP technology can be acceptable in the real clinical applications. A clinical case that has applied RP models successfully for treatment planning and surgical rehearsal is presented. Although the use of RP models is rare in the medical area yet, we believe RP is promising in that it has a great potential in developing new tools which can aid diagnosis, treatment planning, surgical rehearsal, education, and so on.

Intermaxillary fixation is routine procedure to oral and maxillofacial area in jaw bone fracture, surgical correction of jaw deformity, osseus reconstruction of jaw. After transoral surgery, accompanied by intermaxillary fixation, dysphagia or airway obstruction may be followed due to blood clot, vomitus, or laryngeal spasm resulting from irritation by blood or secretions. Lingual or pharyngeal edema is other contributing factors of airway obstruction. In addition, intermaxillary fixation itself may cause obstruction of airway. In this study, pulmonary function test and arterial blood gas analysis were evaluated before and after intermaxillary fixation in 30 patients suffered from mandibular fractures. Comparative analysis was performed by estimated values. The results were as followed. 1. The spirometric values of FEV1, FEV1/FVC and FEF25-75% without intermaxillary fixation were reduced from 97.57%, 85.1%, 98.3,% to 71.7%, 66.5%, 61.2% with intermaxillary fixation, indicating the presence of obstructive pulmonary impairment. 2. Spirometric value of MVV, as the most influencing value of sensitive to extrapulmonary factors, was changed from 84.5% to 46.48%. 3. After intermaxillary fixation, the spirometric value of FVC, as indicator of restrictive pattern of pulmonary function, was not reduced significantly as measured from 94.47% to 89.97%. 4. $O_2$ saturation of arterial blood gas analysis without intermaxillary fixation was 97.86%. While intermaxillary fixation, $O_2$ saturation was 97.47%. The results indicate that careful airway management is mandatory undergoing intermaxillary fixation of various oral and maxillofacial surgery.

사지에 발생한 골육종에서의 사지구제술은 광범위 절제술을 기본으로 한다. 수술 전 항암 치료를 한 뒤에 시행하는 경우가 대부분이라 수술전에 빈혈인 경우가 많고 수술로 인한 출혈이 많아서 수술 전 후 빈혈 교정의 필요성이 대부분 존재한다. 수혈이 암 환자의 예후와 합병증 및 수술 후 치료 결과에 나쁜 영향을 미친다는 다양한 보고들이 있음에도 불구하고 사지 구제술에서 빈혈을 교정하기 위한 방편으로 수혈은 여전히 통상적인 치료로 간주되고 있다. 이에 저자들은 대퇴골 원위부에 발생한 골육종 환자의 사지구제술을 무수혈로 시행하였기에 문헌 고찰과 함께 증례 보고 한다.

This study developed a band-pass filter based artificial filter bank(BAFB) based on that in order to efficiently obtain the significant dynamic responses. The BAFB was then optimized about the El-centro earthquake wave which was often used in the construction research, and the software implementation of BAFB was finally embedded in the wireless unified management system(WiUMS). For the evaluation of the developed BAFB, a real time dynamic response experiment was performed on a cable-stayed bridge model, and the response of the cable-stayed bridge model was measured using both the traditional wired system and the developed BAFB-based WiUMS. The experiment results showed that the compressed dynamic response acquired by the BAFB-based WiUMS matched significantly with that of the traditional wired system while still carrying sufficient modal information of the cable-stayed bridge. Finally, the developed BAFB was able to reconstruct or re-sample the dynamic response wholly from the compressed response signal, and it can be applied as a new kind of measurement system for a wireless sensor networks based structural health monitoring system that secures both economy and efficiency.

Chronic expanding haematoma (CEH) is a rare type of haematoma that enlarges slowly and continuously without coagulation. It can occur following surgery because of shear stress-induced bleeding in the scar tissue between the subcutaneous fat and fascia. We present three cases of large chronic CEH that were successfully treated with triamcinolone injections. Three female patients developed large chronic CEH at 9 months, 5 years, and 6 years, respectively, after latissimus dorsi flap harvesting for breast reconstruction. Although the condition did not improve after multiple sessions of haematoma aspiration in the first two patients, it resolved following a single 40-mg triamcinolone injection along with appropriate compression dressing for several weeks. In the third patient, triamcinolone was injected immediately after the initial aspiration of the haematoma, and the condition improved considerably. There were no side effects in any of the patients. To the best of our knowledge, this is the first report of successful treatment of large CEH using triamcinolone. Therefore, we suggest that triamcinolone injections be considered for the treatment of CEH.

Background In this study, we characterize the morbidity at the donor-site of partial second toe pulp free flaps in terms of wound management as well as long-term outcomes. Methods A single-institutional retrospective review was performed for patients who had undergone partial second toe pulp free flap transfer to the fingertip. Patient charts were reviewed for infection, skin necrosis, wound dehiscence, and hematoma for the donor site. Additionally, a questionnaire survey was given to patients who had a follow-up of longer than 1 year to characterize long-term postoperative pain and appearance. Results The review identified a total of 246 cases. Early wound complications were significant for wound dehiscence (n=8) and hematoma (n=5) for a wound complication rate of 5.3%. The questionnaire was distributed to 109 patients, and 54 patients completed the survey. Out of these 54 patients, 15 patients continued to have donor-site pain (28%) at a mean follow-up period of 32.4 months. However, the pain intensity was relatively low in the range between 2 to 5, on a 0-10 scale. None of these patients felt this donor-site pain interfered significantly with daily activity, nor did any patient require pain medications of any type. Donor-site appearance was satisfactory to most patients. Conclusions The partial second toe pulp flap was associated with low rates of wound complications and favorable long-term outcomes. Given the functional and aesthetic gain in the recipient finger, donor-site morbidities appear acceptable in this patient population. This study can be helpful in counseling patients regarding donor-site morbidity during the informed consent process.

Purpose: Trochanteric pressure sores management has been improved through the development of musculocutaneous flaps. But it has many drawbacks such as donor site morbidity and functional muscle sacrifice. With the introduction of perforator flap, it is possible to use in every location where musculocutaneous perforators are present. We have reconstructed trochanteric pressure sores using perforator-based flaps from the ascending branch of lateral circumflex femoral artery. Methods: Between May of 2006 and April of 2008, we performed six cases of perforator-based flap from the ascending branch of lateral circumflex femoral artery for the coverage of trochanteric pressure sores. For identifying perforators, a line was drawn from the anterior superior iliac spine to the superolateral border of the patella as the vertical axis, from the pubis to the trochanteric prominence as the horizontal axis. In the lateral aspect of the intersection of these two axes, various flap were designed according to its defects. The flap was raised in the subcutaneous plane above the fascia and the pedicle was traced by doppler and identified. The pedicle was meticulously dissected not to injure the periadventitial tissues and transposed to the defect. The donor site was closed primarily. Results: The mean age of patients was 56.2 years. Four male and two female patients were studied. Five patients were paraplegic. The mean defect size was $6{\times}4\;cm$. The largest flap dimension was $14{\times}7\;cm$. Donor sites were closed primarily without any complications. All flaps survived completely without necrosis, hematoma or infection. There were no recurrence during the follow-up period. Conclusion: Trochanteric pressure sores using perforator-based flap from the ascending branch of lateral circumflex femoral artery can be performed safely and it would be a reliable option for coverage of trochanteric pressure sores with minimal donor site morbidity.
