이명은ㆍ정재우(Myoung Eun LeeㆍJae Woo Chung) 유기성자원학회 2016 유기물자원화 Vol.24 No.1

질산과 염산에 의한 대나무활성탄(bamboo-based activated carbon, BAC)의 개질이 Pb(Ⅱ)와 Cu(Ⅱ)의 흡착특성에 미치는 영향을 규명하기 위해 회분식 흡착실험을 수행하였다. 산 개질에 의해 BAC의 탄소함량은 감소하고 산소함량은 증가하며 pH는 감소하는 것으로 나타났다. 염산에 의한 개질은 BAC에 뚜렷한 표면 작용기를 첨가시키지 않았으나 질산에 의한 개질은 카르복실기와 OH 작용기를 첨가시키는 것으로 나타났다. BAC와 산으로 개질된 BAC의 중금속 이온 흡착속도는 2차 속도모델에 의해 적절하게 설명될 수 있는 것으로 나타나 흡착반응의 속도가 물리적 흡착보다는 흡착제와 금속이온들 사이의 전자들의 공유나 교환을 포함하는 화학적 흡착에 의해 결정되는 것으로 나타났다. 실험에 사용된 모든 흡착소재의 등온흡착특성은 Langmuir와 Freundlich 모델에 의해 적절하게 설명될 수 있으며 BAC의 염산에 의한 개질은 중금속 이온의 흡착용량에 큰 영향을 미치지 않으나 표면작용기를 첨가시킨 질산에 의한 개질은 Pb(Ⅱ)와 Cu(Ⅱ)의 흡착용량을 각각 36.0%와 27.3% 증가시키는 것으로 나타났다. Effects of acid (HNO3 and HCl) modification on the adsorption properties of Pb(Ⅱ) and Cu(Ⅱ) onto bamboo-based activated carbon (BAC) were investigated through a series of batch experiments. The carbon content increased and oxygen content decreased with acid treatment. HNO3 induced carboxylic acids and hydroxyl functional groups while HCl added no functional group onto BAC. The pseudo-second order model better described the kinetics of Pb(Ⅱ) and Cu(Ⅱ) adsorption onto experimented adsorbents, indicating that the rate-limiting step of the heavy metal sorption is chemical sorption involving valency forces through sharing or exchange of electrons between the adsorbate and the adsorbent. The equilibrium sorption data followed both Langmuir and Freundlich isotherm models. The adsorption capacities of BAC were affected by the surface functional groups added by acid modification. The adsorption capacities were enhanced up to 36.0% and 27.3% for Pb(Ⅱ) and Cu(Ⅱ), respectively by the HNO3 modification, however, negligibly affected by HCl.

Ho-Chang Lee1, Seung-Myoung Son, Yong-Moon Lee, Ji Hae Koo, Song-Yi Choi, Ok-Jun Lee, Eun-Hwan Jeong 충북대학교 동물의학연구소 2012 Journal of Biomedical and Translational Research Vol.13 No.2

Malignant transformation of mature cystic teratoma (MCT) is rare. Sarcomatoid carcinoma is a neoplasm comprising malignant mesenchymal cells and a conventional carcinomatous area. Here, we report on a case of sarcomatoid carcinoma arising from an MCT in the left ovary of a 45-year-old female. A unilocular cyst consistent with MCT was observed; however, a nodule within the cyst was confirmed from the resected ovary. Microscopically, the nodule showed both squamous cell carcinoma and pleomorphic sarcomatous components admixing with each other. Lining epithelial cells at the periphery of the main tumor showed squamous metaplasia. When a sarcomatous component is observed in the ovary tumor, it is important to find a squamous cell component, either benign or malignant.

안동시민과 하류 지역민의 식수원과 농,공업 용수로 중요한 길안천의 저서성 대형무척추동물의 분포상을 파악하고 수질등급에 따른 지표생물군을 이용하여 길안천 수계의 수질을 종합적으로 평가하였다. 조사결과 길안천에는 절지동물문, 편형동물문, 환형동물문, 연체동물문, 대형동물문등 총 5문 14목 27과 38속 45종의 다양한 종이 서식하고 있는 것으로 나타났다. 빈부수성 수역의 지표군인 하루살이는 길안천 전 수계에 널리 분포하고 있으며, 우점종으로 나타났다. 그 외에 빈부수성과 β-중부수성을 지표하는 횐색 깔다구가 높은 출현도를 보였다. 그러나 길안천이 유속이 빠르고, 주변식생이 빈약하며 하상구조가 단일형의 암석구조로만 이루어져 있는 중상류 하천 특유의 자연환경을 나타내고 있어, 잠자리류와 딱정벌레류, 노린재류등 이에 적응하지 못한 종들의 출현은 저조하게 나타났다. 지표생물군을 이용한 길안천 수계의 수질평가는 β-중부수성으로 판정되었다. We investigated the water Quality in the Kilan stream which has important roles of the use for drinking, irrigation and industry In the Andong area. The research has been performed one time in each month from January to July In 1995. The research was focused on the comprehensive evaluation of water quality in the Kilan stream using a benthic macroinvertebrate as index organisms whose distribution is related to the water quality. The total number of benthic macroinvertebrate taxa were composed of 45 species, 38 genera, 27 families, 14 orders and 5 phyla. Ephemeroptera was the dominant species. Subsequently, Trichoptera and Chironomidae (white) were the second dominant species. Several organisms such as Odonata, Coleoptera, and Hemiptera were found less number because the water speed in the river is a little fast, and simple bottom. Finally, we determined the water quality as β-mesosaprobic using a index organisms in the Kilan stream.

Purpose: This study researched the comparison of oral care methods between the wet gauze and the water gargling for nasal surgery patients. It executed to find out more effective method to relieve thirst. Method: We divided two groups; the wet gauze and the cold water garaling. We assessed patient's oral cavity state and sebjective oral dryness for three times; firstly before the intervention, secondly 15 minutes after 1st intervention and thirdly 15 minutes afrer 2nd intervention. Result: As the intervention, there was no difference on oral condition subhectvely, but there was a difference on thirsty reduction objectively. As the aral dryness has relieved through both methods. It showed the repeated gargling helps more to relieve oral dryness effectively than the wet gauge. At PACU, post nasal surgery patient's oral dryness was decreased with gauze more than two times, patient's oral dryness was relieved. Whereas the dryness was relieved after applying the cold water gargling for just one time. Conclusion: The water gargling is more effective intervention than the wet gauze. Especially, oral dryness was improved in the section of objetive oral assessment index.

In the head and neck area, there are so many sensory nerves, which are sometimes injuried iatrogenically or inadvertently so that involved patients complained of the loss of sensations. In such cases, it is important to judge the degree of injuries and regeneration of nerve for better diagnosis and treatment. Seddon and Sunderland's classification, which is commomly used, is focused on histological change and nerve conduction. As times goes by, it is difficult to access patient's sensory disturbance by this method. Until now, so many methods such as contract threshold, direction, two-point discrimination, pin prick, thermal discrimination and current perception threshold have been introduced for sensory evaluation. However, there hasn't been enough information regarding each methodology nor integrated standard methodology for the measurement. the purpose of this study is to get Korean adult normative sensory values of lower lip,chin and tongue using modified methods of contact thershold, ditection, two point discrimination, pin prick, thermal discrimination and assess degree of regeneration of sensory nerve damage.

The surgery of oral and maxillofacial area poses the risk of cranial nerve damage such as trigeminal nerve or facial nerve. Inferior alveolar nerve is prone to damage in the third molar extraction, implant installation, orthognathic surgery, open reduction and rigid fixation, and tumor ablation surgery. On the other hands,facial nerve is likely to be damaged or sacrificed with trauma or parotidectomy. In case of inferior alveolar nerve injury, the incidence is reported to be about 1.3%. The nerve function will almost recover in minimal damage, but it won't recover at last in total damage of a part of nerve unit. In latter cases, nerve regeneration in intended by allograft as nerve substitute or various route of merve condit. But the recovery with autograft is believed to be most relialbe mrthod in the rapair of long-span(longer than 15㎜)nerve defect. We have performed autologous sural nerve graft in the repair of nerve defect, which is caused by resection of benign or malignant tumor. Hereby we report the method of nerve harvesting, recovery of defected peripheral nerve and the complications of donor site with the discussion of sural nerve anatomy.

The purpose of this study was to examine the influence of stress, body satisfaction, academic record, and demographic variables on the normative conformity toward clothing and clothing satisfaction of high school students. The subjects were 389 high school students(boys: 169, girls: 220) in Seoul, Korea. The normative conformity toward clothing measured by the degree of wearing of unsuitable clothes for school clothing and private clothing norm of students. The school clothing was influenced by allowance, gender, stress of home fife, academic record(-), mothers education(R^=.270). The private clothes was influenced by allowance, gender, stress of home life, body satisfaction, and geographical region (R^2=.200). The clothing satisfaction was influenced by body satisfaction, gender, allowance, geographical region, and stress of home life(-) (R^2=.325). The present findings provide that stress of home life, gender, and allowance had effect on the normative conformity toward clothing, and the higher the stress of home life, the lower the degree of clothing satisfaction.

The purpose of this study was to determine the effect of DHEA with dexamethasone on body weight and wet weight and relative weight of atrophied hindlimb muscles induced by dexamethasone treatment. 200~225g Wistar rats were divided into control(C), dexamethasone(D), dexamethasone and DHEA(DDH) groups. Dexamethasone was injected daily at a dose of 5mg/kg. DHEA was administered daily at a dose of 5mg/kg by oral ingestion during 7days. The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. Body weight and muscle weight of plantaris and gastrocnemius of dexamethasone group decreased significantly compared with that of control group. Muscle weight of plantaris of DDH group increased significantly compared with dexamethasone group. Body weight of DDH group decreased significantly compared to control group, but relative weight of plantaris and gastrocnemius of DDH group increased significantly compared to control group. Based on these results, it can be suggested that DHEA administration during dexamethasone treatment can increase weight of atrophied plantaris muscle induced by dexamethasone treatment.
