Purpose: This study was done to develop a school-based anger management program (SAMP) of 4 sessions and examine its effects on the anger, anger expression, psychosomatic responses, psychosocial responses, and immunologic responses in adolescents. Methods: A quasi-experimental study using a nonequivalent control group, pre-post design with repeated measures was used. Chi-square test, t-test, paired t-test, and Fisher's exact test were used to analyze the data. Results: There were no differences between the experimental and control groups in outcome variables except for lymphocytes. However, following additional analyses, statistically significant differences by time point were observed for pain sensitivity, T cell, Helper T (Th) cell, Suppressor (Ts) cell and Natural Killer (NK) cell post-treatment, entrapment and psychosomatic symptoms at the 4-week follow-up, and resilience at the 10-week follow-up for the experimental group. Conclusion: Although some modifications in contents and administration will be required to increase the effectiveness of the program for anger management, SAMP can be used to promote anger management ability in adolescents.

Background: Tarsal tunnel syndrome (TTS) is an entrapment neuropathy of the tibial nerve within fibrous tunnel on the medial side of the ankle. The most common cause of TTS is idiopathic. This is a retrospective study to define the electrophysiological characteristics of idiopathic TTS. Methods: We reviewed the medical and electrophysiological records of consecutive patients with foot sensory symptoms referred to electromyography laboratory. Inclusion of patients was based on clinical findings suggestive of TTS. Among them, patients with any other possible causes of sensory symptoms on the foot were excluded. Control data were obtained from 19 age-matched people with no sensory symptoms or signs. Routine motor and sensory nerve conduction study (NCS) including medial plantar nerve (MPN) using surface electrodes were performed. Result: Twenty one patients (13 women, 8 men, 9 unilateral, 12 bilateral) were enrolled to have idiopathic TTS (total 31 feet). Tinel's sign was positive in 16 feet (51.6%) of TTS and four feet (10.5%) in control group. The statistically significant electrophysiological parameter was difference of sensory conduction velocity (SCV) between sural nerve and MPN. Amplitude of sensory nerve action potential and SCV of MPN were not different significantly between idiopathic TTS feet and controls. Conclusion: Bilateral development in idiopathic TTS was more common. Tinel's sign and difference of SCV between sural nerve and MPN may be helpful for the diagnosis of idiopathic TTS.

직경자동제어장치를 이용한 초크라스키법에 의해 대형 TeO2 단결정을 공기 중에서 성장시켰다. 온도구배를 가능한 한 적게 한 성장조건 하에서 단결정과 도가니의 직경비율을 60-70% 범위에서 양질의 단결정 성장이 가능하였다. 이 때 결정의 품질을 좌우하는 주요 요인은 인상 및 회전 속도였다. 무색 투명한 고품질 단결정을 육성하기 위한 인상속도는 1.2mm/hr 이하였고, 고액계면은 10-23 rpm 이하일 때 볼록하였으며, 25 rpm 이상일 때 오목하였다. 단결정의 성장은 {110} 방향의 종자결정을 사용하였다. 용융체 내의 백금 함량이 증가하면 조성적 과냉이 발생하여, 성장되는 결정 내에 기포가 포획되므로 성장된 단결정의 질이 저하된다. 적외선 측정결과 파수 2,000cm-1 이상에서 완전 투명하였고, 전위밀도를 측정 결과 직경자동제어를 이용한 경우 3×103/cm2 - 2×104/cm2로 양호하였으며 수동성장인 경우도 결정과 도가니의 직경비율이 40-45%의 범위에서는 매우 양호하였다. 또한 포유물 등 불순물에 혼입 원인에 대하여 논하였다.

Objectives : The purpose of this case is to report the improvement after treatment about a patient with meralgia paresthetica. Methods : We treated the patient with acupucture therapy, cupping therapy, electroacupuncture therapy, percutaneous radiofrequency thermoablation and myofascial release technique by Turbo SASO from $26^{th}$ June 2015 to $3^{rd}$ July 2015 by evaluating femoral function with VAS score. Results : After 5 times of treatment, this patient achieved excellent outcome following the technique, showing that clinical symptom as able to walked and pain was disappeared, VAS changed from 10 to 3 and the result of patrick test came out negative. Conclusions : The various symptoms appear in the Meralgia paresthetica such as numbness, paresthesia, and pain in the anterolateral thigh, which may result from either an entrapment neuropathy or a neuroma of the lateral femoral cutaneous nerve(LFCN). Oriental medical treatment for meralgia paresthetica resulted in satisfactory results by diminishing the symptoms progressively during the five days of treatment. Differential diagnosis was based on careful physical examination. More research of meralgia paresthetica is needed.

The activated sludge obtained from wastewater coke oven plant was immobilized by entrapment with polyethylene glycol (PEG). The effects of several factors on the biodegradation of $CN^-$ from. synthetic wastewater were investigated using batch and continuous reactors. The degradation rate of $CN^-$ increased with increasing of the immobilized bead volume in the reactor. Approximately 7.65mg/L of $NH_4-N$ was produced upon the degradation of 35mg/L of $CN^-$. When high concentrations of the toxic cyanide complex were used in the testing of cyanide degradation, the free activated sludge could be inhibited more than that of the immobilized activated sludge. When the phenol concentration was higher than 400mg/L in the synthetic wastewater, approximately 98.4% of $CN^-$ was removed within 42 hours by the immobilized activated sludge. However, the cyanide was not completely degraded by the tree activated sludge. This indicates that high phenol concentrations can act as a toxic factor for the free activated sludge. A $CN^-$ concentration of less than 1mg/L was achieved by the immobilized sludge at the loading rate of 0.025kg $CN^-/m^3-d$. Moreover, it was found that the HRT should be kept for 48 hours in order to obtain stable treatment conditions.

Biofilm 내부의 항생제 내성 박테리아의 성장형태는 만성감염과 질병을 발생한다. 인위적 형성한 biofilm의 체외실험 모델 시스템 통한 항생제 침투 실험을 수행하였다. 항생제 내성 균주 (E. coli, S. aureus)는 항생제 내성균주 은행으로부터 획득하였다 Ca-alginate bead를 인위적 biofilm으로 사용하였고, 세포 생존률을 향상시키기 위해 공기 압축을 이용한 세포 포획 실험도 측정되었다. biofilm의 항생제 감수성은 항생제의 농도 따라 최저 저해 농도 (MIC)를 이용하여 측정되었다. bead생성에 따른 안정성은 bead를 형성하지 않은 세포와 비교하여 감소하였다. 항생제에 민감한 E. coli의 경우 시간이 지남에 따라 균체수도 감소하였으나, 항생제 내성 E. coli는 일정한 균체수를 유지하였다. bead형성 후 항생제 투여 효과는 항생제 내성이 있고, 낮은 농도의 항생제를 처리할수록 더 높은 생존률을 보였다.

Fexofenadine HCl is non-sedating histamine H1 receptor antagonist that can be used for the treatment of seasonal allergic rhinitis. The objective of this study was to investigate whether the carriers of deformable liposomes can enhance the transepithelial permeability of fexofenadine HCl across the in vitro ALI human nasal monolayer model. Characterization of this model was achieved by bioelectric measurements and morphological studies. The passage 2 and 3 of cell monolayers exhibited the TEER value of $2852\;{\pm}\;482\;ohm\;{\times}\;cm^2$ on 11 days of seeding and maintained high TEER value for 5 days. The deformable liposome of fexofenadine HCl was prepared with phosphatidylcholine (PC) and cholic acid using extruder method. The mean particle size was about 200 nm and the maximum entrapment efficiency of 33.0% was obtained in the formulation of 1% PC and $100\;{\mu}g/ml$ fexofenadine HCl. The toxicity of the deformable liposome to human nasal monolayers was evaluated by MTT assay and TEER value change. MTT assay showed that it has no toxic effect on the nasal epithelial cells in 2-hour incubation when the PC concentration was below 1%. However, deformable liposome could not enhance the transepithelial permeability $(P_{app})$ and cellular uptake of fexofenadine HCl. In conclusion, the in vitro model could be used in nasal drug transport studies and evaluation of transepithelial permeability of formulations.

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy in clinical practice, with a 0.1% life time risk in the general population. Conventional neurophysiological studies have been useful in the diagnosis of this condition, as have a number of more specialized procedures. Therefore, we evaluated the diagnostic sensitivities of several parameters in nerve conduction technique for CTS patients. We analyzed 100 patients (159 hands) who were diagnosed with CTS clinically and electrophysiolosically. Median motor and sensory nerve conduction velocities (MCV and SCV) with wrist, palm, and finger stimulation were performed in traditional methods. Sensitivities of each test were calculated and compared to normal control data. The sensitivities of existing nerve conduction method were noted in terminal latency on median nerve, 2nd finger-wrist segment, 3rd finger-wrist segment, palm-wrist segment and distoproximal ratio, as 72.96%, 92.45%, 94.34%, 94.97%, and 97.48%, respectively. In the early course of CTS, sensory nerve conductions in the median nerve are more valuable than motor nerve conduction. Sensory nerve conductions are usually affected before motor nerve conductions in CTS. In this study, we detected that slowing of median SCV was the most frequent in the distoproximal ratio.
