This study examined the impact of a sand-play therapy program that uses mindful play to facilitate the ego-identity re-formation in middle-aged women. This study involves 12 middle-aged women, with six participants assigned to an experimental group and the other six to a control group. The experimental group participated in a total of 8 sessions, meeting once a week for 90 minutes. To assess the effectiveness of the program, a questionnaire on mid-life crisis, ego-identity, mentalization, and mindfulness was given to both groups at the beginning and end of the therapy program. The study also analyzed the changes in the sandbox made by the participants in the experimental group. The data was analyzed using non-parametric statistical tests, including the Mann-Whitney U test and the Wilcoxon signed-rank test. The main findings of this study are as follows. First, the sand-play therapy was effective in reducing the impact of mid-life crisis. Second, the therapy was helpful in improving ego-identity and mentalization. Lastly, the therapy brought about positive changes in the sandbox which observed by the participants in the experimental group. This study makes an important contribution to this area by supporting the use of structured sand-therapy in analytical psychology and the generalization of sand-play therapy.

Background: Pilomatricoma is a benign, appendageal tumor differentiating towards the normal hair follicles and is characterized by basaloid, transitional, and shadow cells. It is most frequently seen in children; however, a bimodal onset distribution is observed in the first and sixth decades. Objective: The purpose of this study was to analyze the clinical and histopathological features of pilomatricomas in patients over 50 years of age, and to compare these features with those occurring in patients under 20 years of age. Methods: We retrospectively reviewed the medical records and histopathological findings of 73 patients under 20 years and above 50 years of age. The morphological stages of the tumors were analyzed through histopathological findings. Results: The age of patients in the over 50-year age group ranged from 50 to 82 years, with a mean age of 60 years. The male-to-female ratio was 1.1:1. The duration of lesions was from 1 month to several years, with half of the patients having the tumors for over 12 months. The predilection sites were the head (51%), followed by the upper extremities (21%), neck (15%), trunk (6%), and lower extremities (6%). In 73% of the patients over 50 years of age, pilomatricoma was less likely the suspected diagnosis compared with that in the under 20-year age group. Epidermal cysts were most likely suspected in patients over 50 years of age. Histopathologically, half of the tumors were located in the subcutis, which was not significantly different when compared with pilomatricomas in the under 20-year age group. The most common evolutional stage of tumors was early regressive (52%), followed by late regressive (27%), fully developed (15%), and early stage (6%). Capsulation (9%), inflammatory cell infiltration (60%), multinucleated giant cells (36%), calcification (33%), and ossification (12%) were observed. With the exception of capsulation, there were no significant differences in these histopathological features in pilomatricomas in patients over 50 years of age compared with those in patients under 20 years of age. Conclusion: Pilomatrichomas in patients over 50 years of age show no pain, are located in the head and neck, are present for a long duration, and have various clinical presentations when compared with those in patients under 20 years of age. However, they are not rare tumors in adults. Accordingly, pilomatricomas should be included in the clinical differential diagnosis of a solitary, deep skin tumors presenting in adults, especially when they occur on the head.

Kaposi sarcoma (KS) is a multifocal proliferative vascular tumor often caused by human herpes virus 8. Among the four subtypes of KS, classic KS (CKS) is usually chronic, persisting over many years, but is not life threatening. Because the natural history of KS varies, many kinds of therapeutic option for CKS are available and their assessment may be difficult. We experienced three cases of CKS showing HHV-8 positive in biopsy, no history of immunosuppression and HIV infection, normal chest X-ray, no metastasis, and successfully treated with intralesional injection of Pegylated Interferon-α2a (Peg-IFN-α2a). After an intralesional Peg-IFN-α2a injection of 180 mcg/0.5 ml was administered once a week for 4 months, the size and induration of the lesions reduced greatly and the colors faded away. Histopathological examination of the resolved lesions did not show any evidence of KS with negative HHV-8 results. To the best of our knowledge, this is the first report in the literature for the treatment of CKS with intralesional Peg-IFN-α2a injection. (Korean J Dermatol 2014;52(9):646∼650)

본 연구에서는 대한민국 해군 함정의 하절기 운용 및 적도지병 파병 간 발생하고 있는 VRTU 과열로 인한 고온경보 발생과 장비정지 발생현상을 해결하기 위하여 해군 군수사령부 함정기술연구소와 공동연구를 수행하였다. 열전소자 냉각장치 설치에 따른 냉각효과를 확인하고, 전산 열 유동해석을 수행하여 VRTU 내부 열 유동특성을 분석하였다. 또 해석을 통해 기관실(디젤엔진룸) 내부의 온도분포를 살펴보고 VRTU 과열방지를 위한 최적의 설치위치를 알아보았다. 분석결과, 냉각장치를 설치함에 따라 VRTU 내부 평균 체적온도가 약 10 °C 감소하는 것을 확인하였으며 냉각장치에 설치된 Fan은 열 순환을 원활하게 하여 냉각효과를 높였다. 기관실 내부는 디젤엔진 상부에서 높은 온도분포를 나타냈고 통풍관 디퓨저 하부에서 가장 낮은 온도분포를 보였다. 열전소자 냉각장치는 높은 냉각성능을 나타내었으며, VRTU는 과열방지를 위하여 기관실의 통풍관 디퓨저 하부에 설치하는 것이 적절할 것으로 판단된다. This study conducted joint research with the Navy logistics command ship technology research institute to resolve the occurrence of naval vessel"s high-temperature warning and equipment shutdown caused by VRTU overheating during summer operation and the dispatch of troops to equatorial regions. The cooling effect was checked according to the installation of a thermoelectric device cooling system, and heat flow and heat transfer characteristics inside VRTU was analyzed using Computational Fluid Dynamics. In addition, the temperature distribution inside the engine room was assessed through interpretation, and the optimal installation location to prevent VRTU overheating was identified. As a result, the average volume temperature inside the VRTU decreased by approximately 10 °C with the installation of the cooling system, and the fan installed in the cooling system made the heat circulation smooth, enhancing the cooling effect. The inside of the engine room showed a high-temperature distribution at the top of the engine room, and the end of the HVAC duct diffuser showed the lowest temperature distribution.

덕트는 FCU에서 생산된 냉난방 공기를 각 함 내 격실로 수송하기 위한 통로로 이용되는 통풍관을 의마한다. 덕트는 일반적으로 금속재질로 제작되고 있으나, 최근 함정에서는 금속 덕트의 단점을 보완하기 위하여 전투지휘실, 조타실, 음탐기, 조종실 등 주요 격실에 대하여 소음감소효과가 뛰어나고 격실 내에 공기를 골고루 전달할 수 있는 장점을 가진 천 덕트가 대체재로 사용되고 있다. 그러나 함정용 천 덕트는 성능요구조건이 엄격하여 국내에서 생산하지 못하고 있으며 해외에서 전량 수입하고 있는 실정이다. 이 연구에서는 천 덕트는 국산화를 통해 경제적 효과를 창출하기 위하여 국내 업체에서 개발한 천 덕트에 대하여 주요성능 요구조건을 검증하여 보았다. 소음감쇄성능에 대한 자체 검증이 완료된 국산화 천 덕트에 대하여 현재 건조중인 함정에 적용 가능여부를 확인하기 위해 공기투과성능과 방화성능 시험을 수행하여 구매요구사양서에 제시된 성능요구조건 충족여부를 검증하여 보았다. 시험결과 국산화 개발된 천 덕트는 공기투과성능 요구조건과 방화성능 요구조건을 모두 만족하여 건조함정에 적용하기 위한 주요 성능조건을 충족하는 것으로 확인되었다. Metal ducts for transporting air conditioning and heating inside ships have recently been replaced by cloth ducts that have the advantage of delivering air evenly to the compartments, with excellent noise reduction in major compartments, such as combat command rooms, steering rooms, and sound detector cabins. Since the performance requirements of fabric ducts for vessels are strict, and the entire length of the ducts was imported from Korea, the government wants to create economic effects through localization of fabric ducts. Air permeability and fire prevention performance tests verified the applicability to naval vessels of fabric ducts developed by Hyundai Heavy Industries and HiDact, and performance requirements presented in the POS were verified. As a result of the tests, the fabric ducts met the requirements for air permeability and fireproof performance.

Eczematid-like purpura of Doucas and Kapetanakis is a type of pigmented purpuric dermatoses. It is clinically characterizedby pruritic seasonal eruptions occurring in the spring and summer, and histopathologically characterized byspongiosis and parakeratosis in the epidermis and by the lymphocyte-mediated leakage of erythrocytes from capillariesin the papillary dermis. We report a case of eczematid-like purpura of Doucas and Kapetanakis that showedclinical improvement with narrowband UVB (NB-UVB). The patient was a 66-year-old man with pruritic,well-demarcated scaly purpuric patches on his feet that appeared 2 months prior. A histopathological study showedmild superficial perivascular lymphocytic infiltration, focal spongiosis with exocytosis, and erythrocyte leakage. Weinitiated treatment with an oral antihistamine, ascorbic acid, and a topical steroid, but the lesion was aggravated. Wetherefore treated the patient with NB-UVB for 6 months, and the lesions regressed progressively with residual postinflammatoryhyperpigmentation.
