Most of the soundproof tunnels generate significant discharge noise through their inlets and outlets so that the length of the tunnel has been extended frequently than required to minimize the effect on such discharge noise. Thus, in this paper, we investigate reduction capability of discharge noise from the sound proof tunnel installed with lateral sound-absorbing panels on the partitioned truss members in the longitudinal direction of the tunnel. In conclusion, noise field analysis results shows that the sound proof tunnels with lateral sound-absorbing panels have an effect on discharge noise abatement and thereby tunnel``s length reduction.

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)

Annular elastolytic giant cell granuloma is a rare form of granulomatous dermatosis, characterized clinically by annular plaques with slightly elevated margins, and histopathologically by the phagocytosis of elastic fibers by multinucleated giant cells. It typically occurs in sun-exposed areas of the skin in middle-aged women. However, some cases involving unexposed areas have been described. A 57-year-old man had erythematous plaques on both palms accompanied by a sensation of heat for 2 weeks. Histopathological examination revealed granulomatous infiltration with multinucleated giant cells and elastophagocytosis, which is consistent with annular elastolytic giant cell granuloma. Herein we report an interesting case of annular elastolytic giant cell granuloma that occurred on non-sun-exposed skin, palms. (Korean J Dermatol 2016;54(2):133∼135)

In Korea, physician assistants (PAs) have emerged owing to the shortage of medical residents, especially in the surgical departments of tertiary hospitals. In addition, the Korean Ministry of Health and Welfare has been planning to reduce the number of medical residents. Hence, training hospitals decided to hire PAs to replace medical residents. PAs can perform a large part of residents’ time-consuming job. However, PAs are not a common type of workforce in the field of dermatology. The aim of this study is to compare the roles of dermatology specialist, resident, PAs, and registered nurse (RN), and discuss the limitations and futures of PAs in the field of dermatology. Moreover, in Korea, the legal definition and status of PAs are absent or, if present, inconsistent. Between PAs and other positions such as residents, registered nurses, and nurse specialists, lies an unsettled conflict. Therefore, if PAs are employed, a more precise complement is needed.

In the case of steel railway bridges passing through the urban area, many civil complaints are being raised due to such a structure borne noise. A method of attaching a high-efficiency damping panel to a steel plate is proposed as a solution to the structure borne noise, but the behavior according to the exact adhesion rate is not shown. Therefore, in this paper, a basic study for applying a high efficiency damping panel to a steel railway bridges is to measure the mobility according to the adhesion rate of a high efficiency damping panel on a 1m × 1m steel plate.

In the age of Edo, from 17th century to 19th century, for about 260 years, Japanese people had to live under the feudal system of the Tokukawas, As there was no war in Japan in that times, the Chounin class throve, their living conditions got better, so various popular cultures became prosperous. But as it was a male-dominated society and females in the middle of their history were hardly seen, it can't be emphasized that the view of Japanese modem times researched so far with males as the central figure has been half completed. So, to research historical documents to find out Japanese females' interests, thoughts, senses for things, doings and so on could be a way to understand a new side of Japanese modem society and Japanese females who held out the half of the Japan. This research is especially focusing on 〈Tabi〉 of various lives, and show modem-times females' lives and ideologies and females who wrote travel books such poor times. Females in the age of Edo, what did they see and experience in their travels, and how did they change after their travels and live the rest of their lives? To solve these questions, 『AKIKAZENOKI』 written by Shokyuni who was born in Kyushu, leaving her home not getting over current thought, lived a new life with Haikai and traveled in Oushu like Matuo Bashou(a famous poet in Japan), one of 133 travel books and letters collected and analyzed by Siba Keiko of 'Inquiring into modern-times females with their travel books and letters' in the collection of learned papers 'Females in the age of Edo' could be one of the best ways to understand her lives in modem times.
