  • Penetrating wounds to the face are cosmetically devastating and can be life-threatening. If the foreign body causing the penetrating wound is a piece of wood, small remnants might be left behind after the initial treatment. A 33-year-old male patient presented to the emergency center after a piece of lumber pierced his face as a passenger in a traffic accident. The patient's vital signs were stable, and emergency surgery was performed to remove the foreign body and repair the soft tissue. No noteworthy complications were seen after open reduction and internal fixation of the facial bone fractures. Seven months after the accident, the patient underwent scar revision along with full-thickness skin grafting for post-traumatic scars. After the surgery, pus-like discharge which was not previously present was observed, and the graft did not take well. A residual foreign body, which was the cause of graft failure, was found on computed tomography and the remaining foreign body was removed through revision surgery. The patient is receiving outpatient follow-up without any complications 6 months after surgery. This case demonstrates the importance of performing a careful evaluation to avoid missing a residual foreign body, especially if it is of wooden nature.

  • Ergosterol is an indicator chemical of fungi and involves in fungal cell growth as a major component in fungal cell membranes. Thus, this chemical can be used to estimate live fungal biomass within various solid substrates. Ergosterol content in liquid culture of Lentinula edodes had a linear relationship (r=0.98) with the hyphal mass of the fungus. This chemical content differed depending on the fungal strains, age of culture and water content levels of sawdust substrate. Ergosterol content was 0.13% in the 10 weeks old liquid culture while it was 0.10% in 20 weeks old one. The chemical content in the sawdust cultures of the fungus varied 0.015% to 0.042% depending upon strains and water content levels within sawdust substrate. Ergosterol content in the culture of a L. edodes strain, Sanrim 4, was higher by $20{\mu}g$ to $140{\mu}g$/g dry substrate than those of strains, Mok-H and Sanrim 6. And the chemical contents in the sawdust cultures with 125% or 175% water, 297 to 425 ${\mu}g$/g dry substrate, were higher than those with 75% or 225% water, 148 to $286{\mu}g$/g dry substrate. We conclude that ergosterol analysis can estimate the fungal biomass within solid substrate such as logs and sawdust.

  • Recently many scientists have tried to synthesize biodegradable polymers due to durable and non-biodegradable products of conventional synthetic plastics when these were wasted in nature. So to reuse the wastepapers for biodegradable polymer resources, ONP (old newsprint), OCC (old corrugated containerbpard) were carried out by the pretreatment of chlorinite, hypochlorite and oxygen-alkali treatment conditions. For manufacturing of biodegradable polymer with wastepaper, this study performed to investigate change of chemical components and optimal pretreatment condition. The summarized results in this study were as follows: Lignin content in ONP and OCC was was higher than in MOW and ash content was the highest in MOW. More amount of ash components were reduced by wet defiberation than by dry defiberation. Wet defiberation fiber are better than dry defiberated fiber in chemical pretreatment condition for wastepapers, and the best result was obtained in the condition of sodium chlorite at $70^{\circ}C$, because it has high delignification ratio, ${\alpha}$-cellulose contents and degree of polymerization in this treatment condition. Oxygen-alkali treatment condition is the worst method because of low yield, low degree of polymerization in this pretreatments.

  • This study is for species identification for each structure member such as Pillar, Bo, Changbang, Dori, Jangyeo, Judu, Donjaju, Chunyeo, Guitle, and Jongdae, of Pungnammun Gate (Treasure 308). Jeonju is the birthplace of Joseon Dynasty and Pungnammun Gate was the southern gate of old Jeonjueupseong which was walled town. Provincial Governor of Koryeo Dynasty, Yu Gyeong Choi built Jeonjubuseong and four gates at all cardinal points in 1388. And the gate was burnt down by Jeongyujaeran (war with Japan in 1597). It was rebuilt by King Yeongjo (Joseon Dynasty) in 1734 and renamed 'Pungnammun' after 34 years. It was designated for Treasure 308 for its unique style of architecture and historic values in 1963. In this study, all of wooden structure members were Pinus spp.. This result was matched for the result of major species for wooden building of late Joseon Dynasty. It can be used to complete database for architecture of Castle's Gate and help for restoration of cultural heritage in the future.

  • The present study investigated the effect of perch material type (wood and steel) on performance, blood characteristics, and feather pecking. A total of 1,700, one-day-old female Hy-Line brown chicks were evenly assigned to two treatments (wood and steel). The body weight and uniformity of birds were investigated over a 10-week experimental period. Blood characteristics and feather pecking was conducted at week 10. The wood perch treatment (WP) and steel perch treatment (SP) did not differ in their body weight, uniformity, and serum biochemical profile (except inorganic phosphorus) of pullets. Inorganic phosphorus on serum in WP significantly higher than that in SP (P<0.05). Blood corpuscle composition (leukocyte, erythrocyte, and Heterophil / Lymphocyte ratio) of pullets did not show any significant differences among treatments at week 10. Serum corticosterone and feather score that is stress and welfare indices were not affected by the type of perch material. In conclusion, our results suggest that performance, blood characteristics, and feather pecking of pullets were not affected by the perch material type. The results of this study can serve as basic data for investigating the effects of perch type on layer pullets.

  • In oriental medicine, from old times, psychological therapy has been regarded as physical therapy that has been inseparable from psychological therapy. The major objects for oriental psychological therapy is human emotions. Human emotions can be put in the seven feelings(七精) that include Joy(善), Anger(怒), Grief(思), Pity(悲), Fear(恐), Surprise(驚). The seven feelings are connected with human physiology. If each of the seven feelings if excessive, human physiology loses its valance. So the seven feelings are major causes of diseases. The specific character of oriental neuropsychiatry is to make use of the seven feelings in clinical treatment. These oriental neuropsychiatry therapies are performed through consultation with the patient. Of these therapies, Oh-Ji-Sang-Seung(五志相勝療法) is based on the theo교 of interrelation in five elements(metal, wood, water, fire, and earth) in oriental medicine. Specially the sequential subjugations of the five emotions are applied. The contents of Oh-Ji-Sang-Seung(五志相勝療法) include five subjugations of five emotions. Anxiety subjugates fear(思勝恐), fear subjugates joy(恐勝喜), joy subjugates pity(喜勝悲), pity subjugates anger(悲勝怒) and anger subjugates anxiety(怒勝思). The psychological therapy of Oh-Ji-Sang-Seung(五志相勝療法) can be applied in all area of neuropsychiatry. These days, many mental diseases such as Panic Disorder, Depression Somatoform disorders, and negative symptoms of Schizophrenia have been improved by Oh-Ji-Sang-Seung(五志相勝療法) therapy. Here, we present the treatment cases applied Oh-Ji-Sang-Seung(五志相勝療法) therapy in oriental medicine quoted from old oriental books and the latest treatment cases. Moreover, we hope that many oriental therapist will treat many different patients with mental disorders by Oh-Ji-Sang-Seung(五志相勝療法) therapy.

  • Micro-climate measurements and computational fluid analysis were conducted to use it as basic data for the preservation and management of the old house of Kim Myung-kwan, a traditional building that is National Folk Cultural Property No. 26. As a result of the actual measurement, the temperature and humidity are relatively evenly distributed indoors unlike outdoors, but the temperature and humidity vary depending on the time change and the installation location in the outdoors. It was found that the temperature increases after dawn and the temperature varies depending on the installation position around 14:00-15:00, when the temperature becomes the highest. In particular, the temperature was high at the outdoor measurement point adjacent to the building and the fence. As a result of the computational fluid analysis, the temperature was high in the buildings and fences in the old house or in the area adjacent to the building, and it was about 1℃ higher than the surrounding area. In this area, it is judged that the thickening of wood will occur more severely than in other locations, and special preservation management is required.
