Background Mastectomy in male transgender patients is an important (and often the first) step toward physical manhood. At our department, mastectomies in transgender patients have been performed for several decades. Methods Recorded data were collected and analyzed for all male transgender patients undergoing mastectomy over a period of 24 years at our department. Results In total, 268 gender-reassigning mastectomies were performed. Several different mastectomy techniques (areolar incision, n=172; sub-mammary incision, n=96) were used according to patients' habitus and breast features. Corresponding to algorithms presented in the current literature, certain breast qualities were matched with a particular mastectomy technique. Overall, small breasts with marginal ptosis and good skin elasticity allowed small areolar incisions as a method of access for glandular removal. In contrast, large breasts and those with heavy ptosis or poor skin elasticity often required larger incisions for breast amputation. The secondary correction rate (38%) was high for gender reassignment mastectomy, as is also reflected by data in the current literature. Secondary correction frequently involved revision of chest wall recontouring, suggesting inadequate removal of the mammary tissue, as well as scar revision, which may reflect intense traction during wound healing (36%). Secondary corrections were performed more often after using small areolar incision techniques (48%) than after using large sub-mammary incisions (21%). Conclusions Choosing the suitable mastectomy technique for each patient requires careful individual evaluation of breast features such as size, degree of ptosis, and skin elasticity in order to maximize patient satisfaction and minimize secondary revisions.

Dermatomyositis is characterized by progressive, symmetric, proximal muscle weakness and a nonsuppurative inflammatory myopathy of unknown etiology involving predominantly skeletal muscles. It is also characterized by typical skin lesions. Interstitial lung disease has a poor prognosis when it is associated with dermatomyositis. Organizing pneumonia is a disease in which granulation tissue fills the lumina of terminal and respiratory bronchioles and extends into the distal airspaces. The cryptogenic nature of the process is appreciated in that organizing pneumonia patterns of injury can be seen in secondary forms of the disease (secondary organizing pneumonia). Organizing pneumonia has been reported to occur in 5~10% in dermatomyositis-polymyositis patients. Anti-histidyl tRNA synthetase antibody (anti-Jo-1) is a predictive disease marker that is reported to occur in up to 70% of patients. We describe a 49-year-old male dermatomyositis patient who presented with organizing pneumonia and was found to have negative anti-Jo-1 antibody.

본 연구는 사전압밀재하공법에 의해 연약지반을 개량시 재하-제하-재재하와 같은 다양한 응력변화에 의한 2차압밀량을 추정하고자, 일정변형률 압밀시험기(CRS)를 응용한 일정재하시험장치(CLR)와 표준압밀시험기를 이용한 단계 재하시험(IL)에 의해 군산점토의 압밀특성을 비교 고찰하였다. 또한 CRS시험 후 임의 팽창시점에서 재재하시 유효과압밀비에 따른 2차압밀특성과 간극비-유효응력-시간관계 등을 파악하였다. 군산점토는 유효 과압밀비가 클수록 팽창량은 크고 2차압밀 침하량은 작게 발생하고 있으며, 일시에 하중 제거 후, 재하하는 경우에서 2차압밀계수 $C'_{\alpha}$ 는 완속제거시 보다 작게 평가되고, 유효 과압밀비가 1.4이상인 경우는 유사한 값을 제시하고 있다. 재재하시 발생되는 전체침하량을 기준으로 한 2차압밀계수 $C"_{\alpha}$는 경과시간에 따라 비선형적으로 증가하나 최종값은 급속제거시와 비교하여 유사한 값을 제시하고 있다. 간극비 변형속도는 재하시간이 증가할수록 유효 과압밀비에 관계없이 2개의 시험 모두 일정한 선형관계이고, 유효 과압밀비가 증가할수록 작게 나타나고 있다.고 있다.

BACKGROUND/OBJECTIVES: The study objectives were to examine the participation rate in food assistance programs and explore the factors that contribute to such participation among the Korean elderly population. SUBJECTS/METHODS: The study sample comprised 3,932 respondents aged 65 years or older who were selected from a secondary data set, the fourth Korean Welfare Panel Study (KoWePS). The factors, related to participation in programs were examined based on the predisposing, enabling and need factors of the help-seeking behavior model. Multiple logistic regression analysis was used to select the best contributors among the factors related to program participation. RESULTS: The predisposing rate in food assistance programs was 8.5% (7.1% for men and 10.4% for women). When all variables were included in the model, living without spouse, no formal education, low income, having social security benefits and food insecurity in elderly men, and age, low income, having social security benefits and feeling poor in elderly women were significantly related to a higher tendency to program participation. CONCLUSIONS: The predisposing and need factors, such as living without spouse, low education level, food insecurity and feeling poor were important for program participation, as well as enabling factors, such as household income and social security benefits. A comprehensive approach considering these factors to identify the target population for food assistance programs is needed to increase the effectiveness and target population penetration of these programs.

Purpose: The purpose of this study was to explore unmet healthcare needs among low-income overweight and obese women and to identify the factors affecting unmet healthcare needs. Methods: The study was a secondary analysis of data from the 2017 Korea National Health and Nutrition Examination Survey. A final sample of 388 out of 8,127 participants was analyzed using complex descriptive statistics, the chi-square test, the independent t-test, and logistic regression. Results: The mean age of the participants was 66.51±1.05 years. Unmet healthcare needs were experienced by 19.4% of low-income overweight and obese women. Women with depression, stress, and poor self-reported health status were significantly more likely than their counterparts to experience unmet healthcare needs. Poor self-reported health status was confirmed to be related to unmet health needs in low-income overweight and obese women (odds ratio, 2.65; p=.011). Conclusion: The study provides the novel insight that the unmet healthcare needs of low-income overweight and obese women were influenced by self-reported health status. Healthcare providers should make efforts to develop strategies to reduce unmet healthcare needs among low-income overweight and obese women, who constitute a vulnerable population.

An anorthite-based traditional ceramic was developed by adding secondary flux materials to a mixture of kaolin and $CaCO_3$ in order to minimize the deformation during the sintering process. Three flux materials, feldspar, talc, and frit, were evaluated by comparison with two commercial chinaware bodies. Anorthite body with glass frit exhibited poor firing shrinkage. Poor mechanical properties (modulus of rupture, MOR < 30 MPa) was observed for the bodies with feldspar. Another anorthite body was formulated with wollastonite as a Ca source. The fired body showed a MOR of 81 MPa and a shrinkage rate of 6% when wollastonite was added up to 50%. In the XRD analysis, the phase ratio between anorthite and quartz was the highest in the specimen with 50% wollastonite addition. Homogeneous and relatively small closed pores were observed in the microstructural analysis. These results suggest that a ceramic body formulated with 50% kaolin and 50% wollastonite can be fired at $1200^{\circ}C$ with a 6% firing shrinkage rate, giving rise to minimal sintering deformation.

Purpose: The purpose of this study was to investigate the relationships between psychosocial working conditions and psychological well-being depending on the gender among Korean interactive service workers. Methods: This study was a secondary analysis of the data extracted from the 2011 Korean Working Conditions Survey. For the present analysis, 15,669 workers who interact with others at work were selected. Based on the existing literature, a set of variables was chosen from the KWCS. Psychological well-being was measured using the WHO-5 well-being index. Results: The prevalence of poor psychological well-being was significantly higher among men (43.1%) than women (39.6%). Women were more likely to be exposed to demands for hiding emotions, bullying, and discrimination, whereas men were more likely to be exposed to psychological job demands, cognitive demands, demands for responsibility, role conflict and long working hours. Most factors were associated with poor well-being among women and men except demands for hiding emotions, skill discretion and development, physical violence, and sexual harassment. Conclusion: Based on these results, some practical suggestions are offered to help interactive service workers adjust to their duties.

The testicular volume measured by a Prader orchidometer was compared with sperm count in semen, the levels of serum FSH, LH, testosterone, prolactin, estradiol and progesterone in 59 nonobstructive infertile men. 1. The causes of infertility were primary hypogonadisms in 50 patients (35 unknown, 9 Klinefelter syndromes, 6 varicocels) and secondary hypogonadism in 9 (5 isolated FSH deficiencies, 1 hyperprolactinerriia, 3 pituitary hypogonadisms). 2. Decreased levels of serum FSH (less than 4 mIU/ml) did not correlate with testis volume but increased level of serum FSH (more than 20 mIU/ml) were mostly noted in the testis less than 10ml. 3. Decreased level of serum testosterone (less than 3 ng/ml) were distinguishably noted in the atrophied testis less than 5 ml. 4. There was no correlation between the testicular volume and the levels of serum prolactin, estradiol, and progesterone. Coclusively, testicular volume less than 11 ml suggests poor spermatogenesis, but normal testicular volume dose not nessarily rule out poor spermatogenesis. Function of Leydig cell is relatively well preserved in atrophied testis of 5 to 10 ml comparing with that of seminiferous tubule.

본 연구는 저소득 모자가구주의 대부분이 일을 하고 있음에도 불구하고 경제적으로 여전히 어려운 노동빈민(working poor)으로서의 위치에서 벗어나지 못하고 있다는 문제의식 속에서 비롯되었으며, 저소득모자가구의 생활실태를 최근 사회과학 내에서 논의되고 있는 사회적 배제 개념을 이용하여 분석하고 이의 극복방안으로서 사회적 통합과 연대모색을 제안하였다. 구체적으로 본 연구는 남성가장을 중심으로 한 일반가구, 일반 모자가구, 사회적 빈곤선 이하에 놓인 저소득모자가구를 대상으로 각 가구유형별 특성과 생활실태를 비교분석하고 이를 통해 전반적인 모자가구의 사회적 배제과정을 살펴보았다. 본 연구는 2000년 지역사회복지협의회의 "사회복지욕구조사" 원자료를 이차분석(secondary analysis) 하였으며 총 3,182가구가 최종적으로 분석에 포함되었다. 연구결과에 의하면 전반적으로 모자가구는 일반모자가구, 저소득모자가구에 상관없이 고용형태, 주거형태, 소득, 소비생활 측면에서 일반(남성가장)가구에 비해 어려움을 겪고 있었다. 일반가구에 비해 모자가구는 가족으로부터 자원을 제공받기보다는 오히려 장애, 만성질환 등의 가족원을 보호해야 하는 상당한 부담을 안고 있었으며, 사회적 안전망에서도 모자가구는 전반적으로 제외되어 있는 것으로 나타났다. 이것은 모자가구가 일반가구에 비하여 전반적으로 사회적으로 취약해지거나 고립될 가능성이 매우 높은 현실을 반영하며, 현재 공식적으로 빈곤층, 혹은 저소득층으로 분류되지는 않았지만 일반모자가구도 포괄적인 사회적 안전 망이 확립되지 않는다면 향후 저소득층으로 배제될 가능성이 매우 높다는 사실을 확인시켰다. 마지막으로 연구결과에 기초하여, 전체 모자가족의 사회적 배제를 극복할 수 있는 사회적 통합방안이 모색되었다.
