Galactosemia is an inborn error disorder of carbohydrate metabolism, caused by metabolic disturbances at various stages of the Leloir pathway. In patients with galactosemia, accurate diagnosis and appropriate care are essential to avoid complications and unnecessary treatments. And a careful differential diagnosis of the type of galactosemia is crucial. Even with an appropriate galactose-restricted diet, long-term complications may occur, especially in patients with classic galactosemia. So new treatment options are being developed. In this review, we will review the new symptoms of each subtype that have been reported recently and GALM (Galactose mutarotase) deficiency, a new form of galactosemia, and treatment policies according to recent guidelines.

Androgyny of Sword Dance Costumes in the Joseon Dynasty

박가영 대한가정학회 2014 International Journal of Human Ecology Vol.15 No.2

Neo-Confucianism was the dominant ideology of the Joseon Dynasty Korea. Male and female costumesreflected a clear distinction in male and female sex roles. This study analyzes cross-dressing in sword danceperformances. The research method examines relics, paintings, pictures, and documents relevant to sword dancecostumes as well as for the military. The results are: First, the composition of sword dance costume was jeogori(upper garment), skirt, and shoes with military costume of jeollip (hat), jeonbok (long vest), and jeondae (belt). Second, the sword dance costume and military costume are very similar except for the basic inner wear, shoes,some details and methods of wearing. Third, the sword dance costume gradually adopted military items andfeatures. The sword dance costume was basically female, with overall additions of a male costume, to expressan androgynous image; however, the cross-dressing phenomena in the sword dance were not intended for thepursuit of sexual pleasure.

BaZr_0.85-xPd_xY_0.15O_3-_δ/ Carbonates 복합전도체 전기적 특성 연구

박가영,백승석,박준영,Park, Ka-Young,Baek, Seung-Seok,Park, Jun-Young 한국세라믹학회 2014 한국세라믹학회지 Vol.51 No.4

PdO-doped $BaZr_{0.85}Y_{0.15}O_{3-\delta}$ (BZPY) proton conductors have been proposed as applicable for intermediate temperature electrolytes for protonic ceramic fuel cells (PCFCs) because the PdO doping is effective for improving the proton conductivity of $BaZr_{0.85}Y_{0.15}O_{3-\delta}$ (BZY) with high affinity for hydrogen. In order to further improve the conductivity of BZPY, two-phase composite electrolytes consisting of a BZPY and molten carbonate were designed. Dense BZPY-based composite electrolytes were fabricated after sintering at $670^{\circ}C$ for 4 h, since molten carbonates fill the grain boundary of the porous BZPY matrix. Furthermore, BZPY/$(Li-0.5Na)_2CO_3$ composites show a significantly enhanced protonic conductivity at intermediate temperatures. This may be because easy proton transport is possible through the interface of the carbonate and oxide phase.

친군영(親軍營)과 청나라 양식의 군복

박가영 한복문화학회 2022 韓服文化 Vol.25 No.4

This study is on military clothing influenced by the Qing dynasty during the transition period when the traditional military uniforms of Joseon were changed to Western-style. During the enlightenment period, Japan, China, Russia, the United States, Europe, and other countries introduced military training methods and reorganized their military systems, and each country also influenced clothing. Chingunyeong(親軍營) was operated as a three-way system in which the military systems of the Qing dynasty, Japan, and Joseon coexisted. Among them, the two units formed in the Qing dynasty system were called ShingeonChingunyeong(新建親軍營). A military uniform jacket of the ShingeonChingunjwayeong(新建親軍左營) was measured and investigated. It is a jacket with a round collar and long sleeves. The blue jacket has a red edging, and an ocher-colored round insignia is attached to the chest and back. The front insignia is the original, but the back insignia is a photo-printed replica. The insignia was marked with the military camp, rank, and name of the soldier wearing the military uniform. The letters were divided into three types: a red stamp, a black stamp, and black ink. This relic is very similar to the military clothing of the Qing dynasty. It is a daegeum(大襟) magwae(馬褂) that is fastened with an oblique line, and has four slits on the front, back, left, and right sides. Moreover, according to the system of the Qing dynasty, a round insignia was attached to the chest and back. The Yeoui(如意) pattern decoration is also characteristic of Qing dynasty clothing. As a result, the military uniform of a soldier belonging to Chingunyeong who had been trained by Yuan Shikai(袁世凱) and the characteristics of Qing dynasty clothing was clearly shown. Therefore, it was possible to confirm the adoption and wearing of the Qing dynasty military uniform. .

Preserved Hippocampal Glucose Metabolism on 18F-FDG PET after Transplantation of Human Umbilical Cord Blood-derived Mesenchymal Stem Cells in Chronic Epileptic Rats

박가영,이은미,서민수,오정수,손우찬,김기수,김재승,강중구,서유진,강경선 대한의학회 2015 Journal of Korean medical science Vol.30 No.9

Human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) may be a promising modality for treating medial temporal lobe epilepsy. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a noninvasive method for monitoring in vivo glucose metabolism. We evaluated the efficacy of hUCB-MSCs transplantation in chronic epileptic rats using FDG-PET. Rats with recurrent seizures were randomly assigned into three groups: the stem cell treatment (SCT) group received hUCB-MSCs transplantation into the right hippocampus, the sham control (ShC) group received same procedure with saline, and the positive control (PC) group consisted of treatment-negative epileptic rats. Normal rats received hUCB-MSCs transplantation acted as the negative control (NC). FDGPET was performed at pre-treatment baseline and 1- and 8-week posttreatment. Hippocampal volume was evaluated and histological examination was done. In the SCT group, bilateral hippocampi at 8-week after transplantation showed significantly higher glucose metabolism (0.990 ± 0.032) than the ShC (0.873 ± 0.087; P < 0.001) and PC groups (0.858 ± 0.093; P < 0.001). Histological examination resulted that the transplanted hUCB-MSCs survived in the ipsilateral hippocampus and migrated to the contralateral hippocampus but did not differentiate. In spite of successful engraftment, seizure frequency among the groups was not significantly different. Transplanted hUCBMSCs can engraft and migrate, thereby partially restoring bilateral hippocampal glucose metabolism. The results suggest encouraging effect of hUCB-MSCs on restoring epileptic networks.

박가영,변하영,문일준,홍성화,조양선,정원호,김명희 대한이비인후과학회 2012 Clinical and Experimental Otorhinolaryngology Vol.5 No.2

Objectives. Treatment of traumatic perilymph fistula (PLF) remains controversial between surgical repair and conservative therapy. The aim of this study is to analyze the outcomes of early surgical exploration in suspected barotraumatic PLF. Methods. Nine patients (10 cases) who developed sudden sensorineural hearing loss and dizziness following barotrauma and underwent surgical exploration with the clinical impression of PLF were enrolled. Types of antecedent trauma,operative findings, control of dizziness after surgery, postoperative hearing outcomes, and relations to the time interval between traumatic event and surgery were assessed retrospectively. Results. All patients had sudden or progressive hearing loss and dizziness following trauma. Types of barotrauma were classified by the origin of the trauma: 4 external (car accident, slap injury) and 6 internal traumas (lifting, nasal blowing,straining). Surgical exploration was performed whenever PLF was suspected with the time interval of 2 to 47 days after the trauma. The possible evidence of PLF was found during surgery in 9 cases: a fibrous web around the oval window (n=3), fluid collection in the round window (RW; n=6) and bulging of the RW pseudomembrane (n=1). In every patient, vestibular symptoms disappeared immediately after surgery. The hearing was improved with a mean gain of 27.0±14.9 dB. When the surgical exploration was performed as early as less than 10 days after the trauma,serviceable hearing (≤40 dB) was obtained in 4 out of 7 cases (57.1%). Conclusion. Sudden or progressive sensorineural hearing loss accompanied by dizziness following barotrauma should prompt consideration of PLF. Early surgical exploration is recommended to improve hearing and vestibular symptoms.
