Objectives : The aim of this study is to assess the career paths and practice patterns of child and adolescent psychiatrists in South Korea. Methods : A survey on demographic data, work environment, opinion on fellowship training program, and current practice patterns was conducted in 76/223 (34.0%) of all child and adolescent psychiatrists (N=223) were from 1980 to 2008. The survey data from the responders were analyzed. Results : More than half of those surveyed were women. The mean age of survey participants was 40.8 years; most were married, and lived in the Seoul National Capital Area. In general, the responders were very satisfied with their work. They worked in private practice, public sector, group practice, and as consultants. Up to 87% of the patients treated were children and adolescents. The most common treatment modalities were medication and parent psychoeducation. Social skills training and play therapy were applied mainly for children aged 4 to 12 years old. Cognitive behavioral therapy and counseling were preferred in adolescents. Conclusion : The current study used a database approach in order to define current practice patterns. These data may be helpful in consideration of future training programs, workforce issues in child and adolescent psychiatry in South Korea, and also in collaboration with other mental health providers.

All living organisms have a biological clock that orchestrates every biological process and function, and this internal clock operates following a circadian rhythm. This biological clock is known to influence various clinical indicators such as blood pressure and body temperature. Also, the fluctuation of signs and symptoms of diseases including pain disorders are affected by circadian rhythm. It has been reported that the pain intensity of various somatic and neuropathic pain disorders show unique pain patterns that depend on the passage of time. The generation of pain patterns could be explained by extrinsic (e.g., physical activity, tactile stimulation, ambient temperature) and also intrinsic factors (neural and neuroendocrine modulation) that are related to the circadian rhythm. It is important to recognize and identify the individual pain pattern in pain therapy to approve treatment outcome. Moreover, chronotherapeutics which considers pain patterns and pharmacokinetics in context of the circadian rhythm could produce greater analgesia in response to medication. However, only a limited number of studies handle the issue of pain patterns according to circadian rhythm and chronotherapeutics in the orofacial region. The present review intends to reflect on the most recent and relevant data concerning the bidirectional relation between pain disorders of the orofacial region and circadian patterns.

Objectives : This study was performed to investigate the research trends of hypertension in Traditional Chinese Medicine(TCM), and it aims to promote hypertension research in Korean Medicine. Methods : We first collected more than 1,900 papers about hypertension research, and finally selected 108 papers related to this study. They were analyzed by the annul situation, the subject of the study, the perspective of TCM, the study stream, the research fields, the diagnostic patterns, and the distinguishing treatments of TCM. Results : The first review about hypertension in TCM was performed in 1963, and the number of studies has increased since 2000s. Doctors and researchers in China tried various diagnostic patterns to treat the patient because the diagnostic patterns were not unified. For this reason, most researches were reported to the diagnostic patterns and the treatments. Also we have discovered the diversity in treatments methods such as not only the typical herbal medicine, acupuncture, and Qigong but also specific treatments like Chuna, herbal acupoints stimulation, footbath, and pillow. Conclusions : Based on the results of this study, it can be proposed as follows : First, the various approach about hypertension in Korean Medicine is required. Second, the domestic research is needed to be extended to the external treatments as the distinguishing treatments of TCM.

Background: Absorbable plates are widely used in open reduction and internal fixation surgeries for facial bone fractures. Absorbable plates are made of polyglycolic acid (PGA), polylactic acid (PLA), polydioxane (PDS), or various combinations of these polymers. The degradation patterns of absorbable plates made from different polymers and clinical courses of patients treated with such plates have not been fully identified. This study aimed to confirm the clinical courses of facial bone fracture patients using absorbable plates and compare the degradation patterns of the plates. Methods: A retrospective chart review was conducted for 47 cases in 46 patients who underwent open reduction and internal fixation surgery using absorbable plates to repair facial bone fractures. All surgeries used either PLA/PGA composite-based or poly-L-lactic acid (PLLA)/hydroxyapatite (HA) composite-based absorbable plates and screws. Clinical courses were confirmed and comparisons were conducted based on direct observation. Results: There were no naturally occurring foreign body reactions. Post-traumatic inflammatory responses occurred in eight patients (nine cases), in which six recovered naturally with conservative treatment. The absorbable plates were removed from two patients. PLA/PGA compositebased absorbable plates degraded into fragments with non-uniform, sharp surfaces whereas PLLA/HA composite-based absorbable plates degraded into a soft powder. Conclusion: PLA/PGA composite-based and PLLA/HA composite-based absorbable plates showed no naturally occurring foreign body reactions and showed different degradation patterns. The absorbable plate used for facial bone fracture surgery needs to be selected in consideration of its degradation patterns.

The purpose of this study was to compare biomechanical factors on badminton shoes between anti-slip outsole and non anti-slip outsole. Six subjects participated in this experiment. For three-dimensional analysis, eight cameras (Oqus 3series, Qualisys) were used to acquire raw data, and then the parameters were calculated and analyzed with Visual-3D. In conclusion, the patterns of spent time during side step, and maximum velocities of CoGs were consistent without joint angles of lower extremities in spite of small differences. Those of GRFs, and moment of lower extremities were absolutely consistent. This trend of biomechanical factors was that Y shoe (ante-treatment) was much greater and PS shoe (treatment) was greater than Y shoe (treatment). (That was, Y shoe (ante-treatment) > PS shoe (treatment) >Y shoe (treatment)). The findings of this study showed that anti-slip outsole was effective and brought increasing performance and decreasing injuries. It is suggested that further study of these phenomena will help understand many aspects of human locomotion, including work, performance, fatigue and possible injuries.

To enhance the functionalities of ginseng, an acid impregnation pre-treatment was applied during red ginseng processing. Acetic, ascorbic, citric, malic, lactic, and oxalic acid were used for the acid impregnation treatment, and total and crude saponin concentrations and ginsenoside patterns were evaluated. Total and crude saponin contents of red ginseng pre-treated by acetic, ascorbic, and citric acid were similar to those of red ginseng without pre-treatment, whereas lactic, malic, and oxalic acid pre-treatment caused a reduction of total and crude saponin in red ginseng. From the high performance liquid chromatography analysis of ginsenosides, increased $Rg_3$ density was shown in red ginseng pre-treated by acetic, ascorbic, and citric acid impregnation. In the case of lactic, malic, and oxalic acid pre-treatment, increased $Rg_1$ density was observed in red ginseng. Increased $Rg_1$ and $Rg_3$ contents due to acid impregnation during red ginseng processing may contribute to improving bioactive functionalities of red ginseng.

Background and Objectives : Though voice therapy is proven to be effective in academia, treatment results and satisfaction level are inconsistent in clinics. The inconsistency may rise from diverse vocal cords misuse patterns in patient population as they suffer from different diseases or have bad phonation habits. In order to overcome the limitation, we uniformized patients' vocal cords with injection laryngoplasty prior to voice therapy. The efficacy of voice therapy and consistency in treatment results after injection laryngoplasty were assessed. Materials and Methods : Patients diagnosed with vocal nodules were either treated with injection laryngoplasty followed by voice therapy (combined treatment group) or voice therapy only (voice therapy group). Each group consisted of 15 patients. Acoustic measures (jitter, shimmer, NHR), aerodynamic measures (MPT, Psub, MAFR), and subjective auditory conscious measures (K-VHI, K-VRQOL) between two groups were analyzed. Results : After treatments, both groups improved in terms of acoustic, aerodynamic, and subjective auditory conscious measures compared to pre-treatment. Combined treatment group had statistically significantly greater improvement in shimmer, P in K-VHI, and PF in K-VRQOL compared to voice therapy group. Conclusion : Injection laryngoplasty treatment prior to voice therapy synergizes in treating patients compared to voice therapy only.

Sludge production from water treatment plants is increasing each year because water resources deterioration is proceeding and water supply facilities are growing due to water demand increase. Water treatment plant sludges can be modified to soil cover in sanitary landfilling site through the lime treatment and other alternatives. The compression strength of $1.0kg/cm^2$ is necessary for the dozer operation on soft son cover material at municipal landfilling site. Modified sludge was experimentally produced in this study with lime, bentonite, loess, and activated loess dosing. X-ray diffraction patterns of the limed water treatment plant sludge confirmed the presence of calcium carbonate and ettringite. Unconfined compression strength properties of modified sludges showed material property improvement applicable for soil cover alternatives. When adding 20-30% activated loess to water treatment plant sludges. the modified sludges could reach the compression strength for cover soil after 7 days solidification reaction, but decrease of compression strength was intentioned in 28 days reaction period. Solidification effect of the modified sludge with activated loess was observed through the scanning electron microscope.
